    DESCRIPTION OF THE EMBODIMENTS

    [0044] Some embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of embodiments of the present disclosure, not all of them. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those ordinarily skilled in the art fall within the scope of protection of the present disclosure.

    [0045] Unless otherwise specified in the context, throughout the description and the claims, the term comprise and other forms thereof, such as the third-person singular form comprises and the present participle form comprising are construed in an open and inclusive meaning, that is, comprising, but not limited to. In the description, the terms one embodiment, some embodiments, exemplary embodiments, example, specific example, or some examples, etc. are intended to indicate that a particular feature, structure, material, or characteristic related to the embodiment or example is included in at least one embodiment or example of the present disclosure. The schematic illustration of the above terms does not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be included in any one or more embodiments or examples in any suitable manner.

    [0046] Hereinafter, the terms first and second are for descriptive purposes only, and are not to be understood as indicating or implying relative importance or as implicitly indicating the number of technical features indicated. Thus, features limited by first and second may expressly or implicitly include one or more features. In the description of embodiments of the present disclosure, unless otherwise specified, a pluralitymeans two or more.

    [0047] In describing some embodiments, the expressions coupled and connected and extensions thereof may be used. The term connected is to be understood in a broad sense, for example, connected may refer to a fixed connection, may also refer to a detachable connection, or an integral connection; and it may refer to a direct connection or an indirect connected through an intermediate medium. The term coupled indicates that two or more components are in direct physical or electrical contact. The term coupled or communicatively coupled may also indicate that two or more components are not in direct contact with each other, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the contents herein.

    [0048] At least one of A, B, and C has the same meaning as at least one of A, B, or C, encompassing the following combinations of A, B, and C: only A, only B, only C, a combination of A and B, a combination of A and C, a combination of B and C, as well as a combination of A, B, and C.

    [0049] A and/or B includes three combinations of only A, only B, and a combination of A and B.

    [0050] The use of suitable for or configured to herein means open and inclusive language that does not exclude devices suitable for or configured to perform additional tasks or steps.

    [0051] As used herein, about, approximately, or approximately includes a stated value as well as an average within an acceptable range of deviation from a particular value, where the acceptable range of deviation is determined by one of ordinary skill in the art taking into account the measurement in question and the error associated with the measurement of a particular amount (i.e., limitations of the measurement system).

    [0052] As used herein, terms such as parallel, perpendicular, and equal encompass both the stated conditions and conditions that are approximate to the stated ones, with the range of approximation falling within an acceptable deviation, where the acceptable range of deviation is as determined by a person of ordinary skill in the art taking into account the measurement in question and the error associated with the measurement of a particular quantity (i.e., limitations of the measurement system). For example, parallel encompasses both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for instance, within 5 of deviation; similarly, perpendicular includes both absolute perpendicularity and approximate perpendicularity, with an acceptable deviation range for approximate perpendicularity that can also be, for example, within 5 of deviation. Equal encompasses both absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two quantities being compared that is less than or equal to 5% of either quantity.

    [0053] In related technologies, an electric control box and an electric reactor are typically connected together and then mounted in a case of a mobile air conditioner. However, the size is large after the electric control box and the electric reactor are connected together. Thus, a large space is occupied after the electric control box and the electric reactor are mounted in the case of the mobile air conditioner, which is adverse to the arrangement of components in the case, and affects the utilization of the space in the case.

    [0054] At present, a heat exchanger and a compressor of the mobile air conditioner are typically fixed to a base. In order to reduce the vibration transferred from the compressor to the base, the compressor is fixed to the base, and thus the vibration transferred from the compressor to the base during operation can be reduced. Moreover, due to the limited internal space of the mobile air conditioner, the distance between the compressor and the heat exchanger is short, and when the mobile air conditioner is being transported or the compressor shakes greatly, the situations that the compressor and the heat exchanger interfere with each other and the heat exchanger is extruded and deformed are easily caused by the inclination of the compressor. Besides, the problem that a condenser has a poor heat dissipation effect also exists.

    [0055] In order to solve the above technical problems, some embodiments of the present disclosure provide a mobile air conditioner 100.

    [0056] It should be noted that the difference between the mobile air conditioner and an ordinary air conditioner lies in the air duct circulation design, air volume circulation of the ordinary air conditioner aims at the indoor air circulation, and the mobile air conditioner sucks outdoor fresh air while reducing the indoor air temperature. Substantially, the ordinary air conditioner performs heat exchange for cooling and heating through an outdoor compressor, and the mobile air conditioner performs same only through an indoor unit.

    [0057] The mobile air conditioner 100 can adjust the temperature in a local range, has a small size, is convenient to move according to requirements, and is good in flexibility.

    [0058] With reference to FIG. 1, the mobile air conditioner 100 is an air conditioner integrating an indoor unit and an outdoor unit. According to the mobile air conditioner 100, components such as a compressor, a condenser and an evaporator are disposed in a case 1, and the outlet air temperature of the mobile air conditioner 100 is adjusted through an electric control board in an electric control box. Some mobile air conditioners having both cooling and heating functions often use four-way valves to switch between cooling and heating.

    [0059] With reference to FIG. 1, the mobile air conditioner 100 includes the case 1. The case 1 includes a base 11 and a first housing 12. A first cavity is formed in the case 1. For example, the first cavity is formed in the first housing 12, and the bottom of the first housing 12 is opened with a first opening in communication with the first cavity. The base 11 covers the first opening and is connected to the first housing 12.

    [0060] In some embodiments, with reference to FIG. 2, the mobile air conditioner 100 further includes a first air duct shell 2. The first air duct shell 2 is located in the first cavity and fixedly connected to the case 1. For example, the first air duct shell 2 can be fixed to the base 11 and can also be fixed to the first housing 12, and a mounting cross beam can also be disposed in the middle of the first cavity, and the first air duct shell 2 is fixed to the mounting cross beam.

    [0061] To facilitate the description, the first air duct shell 2 being disposed in the middle of the first cavity is mainly taken as an example for explanation.

    [0062] In some embodiments, with reference to FIG. 3, the first housing 12 further includes a first air inlet 121. With reference to FIG. 1, the first housing 12 further includes a first air outlet 122. With reference to FIG. 2, a first air duct 21 is formed in the first air duct shell 2, the mobile air conditioner further includes a first fan disposed in the first air duct 21, the first air inlet 121 is in communication with an inlet of the first air duct 21, and the first air outlet 122 is in communication with an outlet of the first air duct 21. Thus, the air outside the case 1 can be drawn into the first air duct 21 by the first fan through the first air inlet 121, and then be discharged out of the case 1 through the first air outlet 122.

    [0063] In some embodiments, with reference to FIG. 2, the mobile air conditioner further includes a first heat exchanger 3. The first heat exchanger 3 is located in the first cavity and fixed to the case 1. For example, the first heat exchanger 3 is fixed to the base 11 and can also be fixed to the first housing 12, and the first air duct shell 2 can also be fixed to the mounting cross beam. Besides, the first air duct shell 2 can also be disposed above the first heat exchanger 3 and a compressor 4.

    [0064] It should be noted that the first heat exchanger 3 being fixed to the base 11 is mainly taken as an example for explanation below. In this case, the first heat exchanger 3 is spaced apart from the first air duct shell 2, for example, the first air duct shell 2 is located on the side of the first heat exchanger 3 away from the base 11.

    [0065] In some embodiments, with reference to FIG. 2, the mobile air conditioner further includes the compressor 4 and a second heat exchanger 5. The compressor 4 and the second heat exchanger 5 are respectively disposed in the first cavity, and the compressor 4 is fixed to the base 11 and spaced apart from the first heat exchanger 3. The second heat exchanger 5 is disposed on the side of the first heat exchanger 3 away from the base 11, and is connected to the first air duct shell 2. In some embodiments, the compressor 4 is fixed to a support rod 125. The position of the first heat exchanger 3 and the position of the second heat exchanger 5 are interchangeable.

    [0066] The compressor 4, the first heat exchanger 3 and the second heat exchanger 5 are sequentially connected through pipelines. The mobile air conditioner further includes an electronic expansion valve disposed between the first heat exchanger 3 and the second heat exchanger 5, and the electronic expansion valve is configured to perform throttling and pressure reduction on a refrigerant flowing through. The refrigerant in the mobile air conditioner can flow among the compressor 4, the first heat exchanger 3 and the second heat exchanger 5, such that the refrigerant flowing through the second heat exchanger 5 exchanges heat with the air flowing through the first air duct 21, thereby adjusting the temperature of the air flowing through the first air duct 21. The air subjected to temperature adjustment is blown into a room outside the case 1 from the first air outlet 122, so as to adjust the indoor temperature.

    [0067] It should be noted that during cooling by the mobile air conditioner, the first heat exchanger 3 serves as a condenser, and the second heat exchanger 5 serves as an evaporator.

    [0068] The refrigerant in the mobile air conditioner is compressed into a high-temperature and high-pressure refrigerant by the compressor 4, the high-temperature and high-pressure refrigerant flows out of the compressor 4 to enter the first heat exchanger 3 and is condensed into a high-temperature and high-pressure liquid refrigerant by the first heat exchanger 3, the high-temperature and high-pressure liquid refrigerant flows out of the first heat exchanger 3 to enter the electronic expansion valve and is throttled and depressurized into a low-temperature and low-pressure liquid refrigerant by the electronic expansion valve, the low-temperature and low-pressure liquid refrigerant flows out of the electronic expansion valve to enter the second heat exchanger 5 and is evaporated into a low-temperature and low-pressure gaseous refrigerant by the second heat exchanger 5, and the low-temperature and low-pressure gaseous refrigerant flows out of the second heat exchanger 5 to enter the compressor 4 to be compressed again.

    [0069] The second heat exchanger 5 is connected to one side of the first air duct shell 2, and during the process that the refrigerant is evaporated by the second heat exchanger 5, the refrigerant can exchange heat with the air flowing through the first air duct 21, thereby cooling the air flowing through the first air duct 21. The cooled air is blown into the room outside the case 1 from the first air outlet 122, so as to cool the indoor air.

    [0070] During heating by the mobile air conditioner, the first heat exchanger 3 serves as the evaporator, and the second heat exchanger 5 serves as the condenser.

    [0071] The refrigerant in the mobile air conditioner is compressed into the high-temperature and high-pressure refrigerant by the compressor 4, the high-temperature and high-pressure refrigerant flows out of the compressor 4 to enter the second heat exchanger 5 and is condensed into the high-temperature and high-pressure liquid refrigerant by the second heat exchanger 5, the high-temperature and high-pressure liquid refrigerant flows out of the second heat exchanger 5 to enter the electronic expansion valve and is throttled and depressurized into the low-temperature and low-pressure liquid refrigerant by the electronic expansion valve, the low-temperature and low-pressure liquid refrigerant flows out of the electronic expansion valve to enter the first heat exchanger 3 and is evaporated into the low-temperature and low-pressure gaseous refrigerant by the first heat exchanger 3, and the low-temperature and low-pressure gaseous refrigerant flows out of the first heat exchanger 3 to enter the compressor 4 to be compressed again.

    [0072] The second heat exchanger 5 is connected to one side of the first air duct shell 2, during the process that the refrigerant is condensed by the second heat exchanger 5, the refrigerant can exchange heat with the air flowing through the first air duct 21, thereby heating the air flowing through the first air duct 21. The heated air is blown into the room outside the case 1 from the first air outlet 122, so as to heat the indoor air.

    [0073] The mobile air conditioner generates heat during the operation process. In order to prevent the heat generated by the mobile air conditioner from affecting the indoor temperature, in some embodiments, with reference to FIG. 4, the mobile air conditioner further includes a second air duct shell 6, and the second air duct shell 6 is fixed to the base 11 and connected to the side of the first heat exchanger 3 facing away from the compressor 4. In some embodiments, the second air duct shell 6 is not fixed to the base 11.

    [0074] A second air duct 61 is formed in the second air duct shell 6. The mobile air conditioner further includes a second fan disposed in the second air duct 61. With reference to FIG. 3, the first housing 12 includes a second air inlet 123 and a second air outlet 124, the second air inlet 123 is in communication with an inlet of the second air duct 61, and the second air outlet 124 is in communication with an outlet of the second air duct 61 and can be in communication with the outside of the room through a pipeline.

    [0075] Thus, the indoor air can be drawn into the second air duct 61 from the second air inlet 123 by the second fan, and the air can be discharged outdoors from the second air outlet 124 and the pipeline in communication with the second air outlet 124, thereby dissipating heat of the case 1.

    [0076] In some embodiments, to rationally utilize the space in the first cavity, with reference to FIG. 2, the mobile air conditioner further includes an electric control box 7 and an electric reactor assembly 8. The electric control box 7 is located on the side of the first heat exchanger 3 close to the first air duct shell 2, and is connected to the side wall of the first air duct shell 2 close to the first heat exchanger 3. Thus, at least part of the electric control box 7 can be disposed in a space (for example, a mounting space) between the first heat exchanger 3 and the first air duct shell 2, thereby utilizing the mounting space. In some embodiments, the electric control box 7 is not connected to the side wall of the first air duct shell 2.

    [0077] When the mobile air conditioner 100 is in an operating state, the change of the current of the mobile air conditioner needs to be limited by the electric reactor assembly 8, thereby protecting circuits of the mobile air conditioner. The operation of the mobile air conditioner 100 is also controlled by an electric control board 74, the electric control board 74 is disposed in the electric control box 7, and the electric control box 7 is configured to protect the electric control board 74.

    [0078] In some embodiments, the electric control box 7 and the electric reactor assembly 8 are respectively disposed in the first cavity and fixed to the case 1, and the electric reactor assembly 8 is spaced apart from the electric control box 7. Thus, the electric reactor assembly 8 and the electric control box 7 can be separately disposed, such that the electric reactor assembly 8 and the electric control box 7 can be disposed in different spaces in the first cavity, and the space in the first cavity can be rationally utilized. The electric control box 7 and the electric reactor assembly 8 can also be combined together to be designed into a combined component for use.

    [0079] In addition, the space individually occupied by the electric reactor assembly 8 and the space individually occupied by the electric control box 7 can be reduced, such that various components of the mobile air conditioner can be more conveniently disposed in the first cavity.

    [0080] For example, a fixing rod is disposed in the middle of the first cavity, and the electric reactor assembly 8 is fixed to the fixing rod.

    [0081] For another example, the electric reactor assembly 8 can also be fixed to the base 11 and spaced apart from the first heat exchanger 3, and the electric reactor assembly 8 is also located on the side of the electric control box 7 away from the first air duct shell 2.

    [0082] For another example, the electric reactor assembly 8 can also be located on the side of the first heat exchanger 3 away from the second air duct shell 6.

    [0083] For another example, the electric reactor assembly 8 can also be fixed to the first housing 12, and can also be fixedly connected to the components such as the first heat exchanger 3 or the first air duct shell 2.

    [0084] In some embodiments, the first heat exchanger 3 may be a tubular heat exchanger or a plate-type heat exchanger. The first heat exchanger 3 being the plate-type heat exchanger is mainly taken as an example for explanation below.

    [0085] In this case, a thickness direction of the first heat exchanger 3 can be perpendicular to a direction in which the first heat exchanger 3 and the first air duct shell 2 are arranged. For example, the thickness direction of the first heat exchanger 3 is consistent with a direction in which the first heat exchanger 3 and the electric reactor assembly 8 are arranged. Thus, the mounting space can be divided into two parts by the first heat exchanger 3, that is, the mounting space includes a first mounting sub-space and a second mounting sub-space, the first mounting sub-space is located on one side of the first heat exchanger 3 in the thickness direction, and the second mounting sub-space is located on the other side of the first heat exchanger 3 in the thickness direction, such that the space in the first cavity can be rationally divided, and the second air duct shell 6 and the electric reactor assembly 8 can be conveniently and separately disposed in the mounting space. For example, one of the second air duct shell 6 and the electric reactor assembly 8 is located in the first mounting sub-space, and the other one of the second air duct shell 6 and the electric reactor assembly 8 is located in the second mounting sub-space.

    [0086] In some embodiments, the thickness direction of the first heat exchanger 3 can be inclined relative to the direction in which the first heat exchanger 3 and the first air duct shell 2 are arranged.

    [0087] In some embodiments, with reference to FIG. 2 and FIG. 5, the mobile air conditioner further includes an electric motor 9 (for example, a water pumping electric motor). The electric motor 9 is fixed to the base 11 and located on the side of the first heat exchanger 3 away from the second air duct shell 6. An output shaft of the electric motor 9 is located above a water receiving pan of the mobile air conditioner, and the electric motor 9 is configured to drive a wind wheel disposed on the output shaft thereof to rotate, so as to spray condensate water generated by the mobile air conditioner to the first heat exchanger 3, thereby facilitating evaporation of the condensate water, increasing the humidity of the indoor air, and reducing the temperature in the first cavity. In some embodiments, the electric motor 9 is not fixed to the base 11, but is fixed to the support rod 125.

    [0088] In some embodiments, in order to rationally utilize the space in the first cavity, the electric reactor assembly 8 can be disposed on the side of the first heat exchanger 3 away from the second air duct shell 6, and the electric reactor assembly 8 can be disposed above the electric motor 9.

    [0089] For example, with reference to FIG. 6, the electric reactor assembly 8 includes a bracket 81 and an electric reactor body 82. The bracket 81 is fixed to the base 11, a first avoidance portion 811 (for example, an avoidance groove) is formed on one side of the bracket 81 close to the base 11, and at least part of the electric motor 9 is located in the avoidance groove; and the electric reactor body 82 is fixed to the bracket 81, thereby supporting the electric reactor body 82 by the bracket 81.

    [0090] It should be noted that in some embodiments, the base 11 includes an electric motor mounting groove, and the electric motor mounting groove is located on the side of the avoidance groove close to the base 11. The electric motor 9 is disposed in the electric motor mounting groove, and at least part of the electric motor 9 can be exposed out of the electric motor mounting groove, so that at least part of the electric motor is located in the first avoidance portion 811.

    [0091] Thus, the electric reactor assembly 8 can be disposed in the space above the electric motor 9 (that is, the side of the electric motor 9 close to the first air duct shell 2), thereby saving the space of the first cavity in a horizontal direction, facilitating the arrangement of other components, reducing the size of the mobile air conditioner 100, and improving the heat dissipation effect of the electric reactor assembly 8.

    [0092] It should be noted that the bracket 81 can be a blocky support seat and can also be a support structure formed by a plurality of components.

    [0093] For example, with reference to FIG. 5, FIG. 6 and FIG. 8, the bracket 81 includes a support 812 and a fixing portion 813 (for example, a fixing plate). The support 812 is disposed adjacent to the first heat exchanger 3, the support 812 is fixedly connected to the base 11, an opening of the avoidance groove faces the base 11, and the first avoidance portion 811 is formed on the side of the support 812 close to the base 11 and penetrates through the support 812 in a third penetrating direction (for example, a direction Y as shown in FIG. 2). Here, the penetrating direction refers to a direction perpendicular to a reference plane jointly defined by a first direction (for example, a direction X as shown in FIG. 2) and a second direction (for example, a direction Z as shown in FIG. 2, also referred to as the height direction).

    [0094] For example, the first direction can refer to the direction in which the first heat exchanger 3 and the second air duct shell 6 are arranged in FIG. 2, and the second direction can refer to the direction in which the first heat exchanger 3 and the first air duct shell 2 are arranged in FIG. 2. The third direction is perpendicular to the reference plane.

    [0095] In some embodiments, the fixing portion 813 is connected to the side of the support 812 away from the base 11, and the thickness direction of the fixing portion 813 is consistent with the penetrating direction. For example, the fixing portion 813 includes a connecting end 8131 and an extending end 8132 opposite each other, the fixing portion 813 is connected to the support 812 through the connecting end 8131, and the extending end 8132 is located on the side of the support 812 away from the base 11.

    [0096] It should be noted that the electric reactor body 82 can be disposed in various manners, for example, the electric reactor body 82 can be connected to the support 812 and can also be connected to the fixing portion 813, thereby improving the fixing flexibility of the electric reactor body 82.

    [0097] The electric reactor body 82 being fixed to the fixing portion 813 is mainly taken as an example for explanation below.

    [0098] For example, with reference to FIG. 7 and FIG. 16, the fixing portion 813 includes two bent portions 8133 spaced apart from each other, and the two bent portions 8133 are located on two opposite sides of the electric reactor body 82 and spaced apart in the first direction. For example, a direction in which the two bent portions 8133 are arranged is parallel to the side surface of the fixing portion 813 close to the electric reactor body 82, and is perpendicular to the direction of the support 812 away from the base 11.

    [0099] Each bent portion 8133 includes a second mounting portion 81331 (for example, a mounting groove) with an opening facing the electric reactor body 82, and in a direction in which the connecting end 8131 and the extending end 8132 are arranged, the second mounting portion 81331 penetrates through the bent portion 8133. A bottom plate of the electric reactor body 82 is snap-fitted in the two second mounting portions 81331.

    [0100] Thus, when the electric reactor body 82 is fixedly connected to the fixing portion 813, all that is needed is to enable the electric reactor body 82 to move next to the fixing portion 813 in the direction from the extending end 8132 to the connecting end 8131, such that the bottom plate of the electric reactor body 82 enters the two second mounting portions 81331, the bottom plate of the electric reactor body 82 is limited by the two second mounting portions 81331, and the electric reactor body 82 is fixedly connected to the fixing portion 813.

    [0101] It should be noted that the two bent portions 8133 can be located on the side surface of the fixing portion 813 close to the electric reactor body 82, and can also be located on two side surfaces of the fixing portion 813 in the direction in which the two bent portions 8133 are arranged. Besides, to fix the electric reactor body 82 to the fixing portion 813 more firmly, at least parts of the second mounting portions 81331 on the two side walls of the fixing portion 813 in the thickness direction abut against the bottom plate of the electric reactor body 82.

    [0102] In some embodiments, the bent portions 8133 can be protruding blocks fixed to the fixing portion 813. Alternatively, the bent portions 8133 can also be formed by stamping from the side of the fixing portion 813 away from the electric reactor body 82 toward the side of the fixing portion 813 close to the electric reactor body 82.

    [0103] On this basis, in order to fix the electric reactor body 82 to the fixing portion 813 more firmly to avoid damage of the electric reactor body 82 due to shaking of the electric reactor body 82 during the operation process, with reference to FIG. 7 and FIG. 14, the fixing portion 813 and the bottom plate of the electric reactor body 82 can be connected through second fasteners 814. For example, the second fasteners 814 can be bolts and nuts, screws and the like.

    [0104] In this case, the bottom plate of the electric reactor body 82 is limited by the two second mounting portions 81331, such that the electric reactor body 82 can be fixed to the fixing portion 813 by connecting each of a group of diagonal positions of the bottom plate of the electric reactor body 82 to the fixing portion 813 through one second fastener 814.

    [0105] Thus, when the electric reactor body 82 is connected to the fixing portion 813, the number of the used second fasteners 814 can be reduced, thereby saving the time for fastening the second fasteners 814, and then improving the connecting efficiency of the electric reactor body 82 and the fixing portion 813.

    [0106] In some embodiments, in order to conveniently clamp the bottom plate of the electric reactor body 82 into the second mounting portions 81331, in the direction from the extending end 8132 to the connecting end 8131, a distance between two side walls of each of the second mounting portions 81331 in the thickness direction of the fixing portion 813 can decrease. For example, an opening at the end of each second mounting portion 81331 close to the extending end 8132 is larger than an opening at the end of the second mounting portion 81331 close to the connecting end 8131.

    [0107] Thus, the bottom plate of the electric reactor body 82 can relatively easily enter the second mounting portions 81331 from the ends of the second mounting portions 81331 close to the extending end 8132, thereby increasing the clamping speed of the bottom plate of the electric reactor body 82 into the second mounting portions 81331, and then improving the connecting efficiency of the electric reactor body 82 and the fixing portion 813.

    [0108] In some embodiments, after the electric reactor body 82 is fixedly connected to the bracket 81, in order to protect the electric reactor body 82, with reference to FIG. 6, the electric reactor assembly 8 further includes a second housing 83. The second housing 83 is provided with a second cavity 831 and a second opening 832 (also referred to as the cavity opening) in communication with the second cavity 831, the bracket 81 covers the second opening 832, and the electric reactor body 82 is located in the second cavity 831. Thus, the electric reactor body 82 can be protected by the bracket 81 and the second housing 83.

    [0109] In some embodiments, the second opening 832 of the second cavity 831 can be formed in two adjacent side walls of the second housing 83.

    [0110] For example, the second housing 83 is located on the side of the support 812 away from the base 11, and is located on one side of the fixing portion 813 in the thickness direction. With reference to FIG. 6, the second opening 832 of the second housing 83 includes a first sub-opening 8321 and a second sub-opening 8322 which are in communication with each other, the first sub-opening 8321 is located on the side wall of the second housing 83 close to the support 812, and the second sub-opening 8322 is located on the side wall of the second housing 83 close to the fixing portion 813.

    [0111] The bracket 81 is configured to open or close the second opening 832. For example, by moving the second housing 83, the support 812 can close or open the first sub-opening 8321, and the fixing portion 813 can close or open the second sub-opening 8322.

    [0112] It should be noted that the first sub-opening 8321 penetrates through the second housing 83 in the direction (the second direction) from the extending end 8132 to the connecting end 8131, and the second sub-opening 8322 penetrates through the second housing 83 in the direction (the third direction) from the electric reactor body 82 to the fixing portion 813, such that the first sub-opening 8321 and the second sub-opening 8322 are in communication with each other to form the second opening 832.

    [0113] When the electric reactor body 82 is in the operating state, the second housing 83 needs to be fixedly connected to the bracket 81, such that the second housing 83 and the bracket 81 cooperate to jointly protect the electric reactor body 82. For example, the second housing 83 and the bracket 81 can be connected through fasteners such as bolts and screws, can also be connected in a snap-fitted manner, and can also be connected through the fasteners and in the snap-fitted manner. For example, with reference to FIG. 6, a second snap-fit portion 833 is formed on the side wall of the second housing 83 away from the support 812, and a second connecting portion 834 is formed on the side wall of the second housing 83 away from the fixing portion 813.

    [0114] With reference to FIG. 7, the support 812 includes a third connecting portion 8121. With reference to FIG. 6 and FIG. 13, a first hole 8134 is formed at the extending end 8132 of the fixing portion 813. The second snap-fit portion 833 is inserted into the first hole 8134 and can be in contact with the side of the fixing portion 813 away from the second housing 83, and the second connecting portion 834 is connected to the third connecting portion 8121 through first fasteners (for example, screws), such that one end of the second housing 83 can be fixedly connected to one end of the bracket 81.

    [0115] It should be noted that when the second snap-fit portion 833 is inserted into the first hole 8134, the second snap-fit portion 833 can be limited by the first hole 8134 in a direction perpendicular to an axial direction of the first hole 8134; besides, the second snap-fit portion 833 is in contact with the side of the bracket 81 away from the second housing 83, such that one side of the second snap-fit portion 833 in the axial direction of the first hole 8134 can be limited by the bracket 81, thereby preventing the other opposite end of the second housing 83 from being separated from the bracket 81, and connecting the other opposite end of the second housing 83 to the other opposite end of the bracket 81.

    [0116] Thus, when the second housing 83 and the bracket 81 are fixed, all that is needed is to insert the second snap-fit portion 833 into the first hole 8134 and connect the first fasteners between the second connecting portion 834 and the third connecting portion 8121, thereby reducing the number of the first fasteners, then shortening the time for fastening the first fasteners, simplifying the assembly process of the second housing 83 and the bracket 81, and improving the assembly efficiency.

    [0117] In some embodiments, the second snap-fit portion 833 can be an L-shaped rod-like inserting member or an L-shaped plate-like inserting member.

    [0118] The second snap-fit portion 833 being the L-shaped plate-like inserting member is mainly taken as an example for explanation below.

    [0119] For example, the second snap-fit portion 833 is disposed on the side wall of the second housing 83 away from the first sub-opening 8321. With reference to FIG. 9 and FIG. 10, the second snap-fit portion 833 includes a first sub-plate 8331 (for example, an inserting plate or an inserting sheet) and a blocking portion 8332 (for example, a blocking sheet). The first sub-plate 8331 is connected to the second housing 83; and one end of the blocking portion 8332 is connected to the first sub-plate 8331, and in a thickness direction of the first sub-plate 8331, the other opposite end of the blocking portion 8332 is located on the side of the first sub-plate 8331 away from the support 812.

    [0120] After the second housing 83 is mounted on the bracket 81, the first sub-plate 8331 passes through the first hole 8134, and the blocking portion 8332 is located on the side of the fixing portion 813 away from the second housing 83 and is in contact with the fixing portion 813, such that the first sub-plate 8331 can be limited by the first hole 8134, and the blocking portion 8332 can be limited by the fixing portion 813, thereby improving the connection reliability of the second housing 83 and the bracket 81.

    [0121] Besides, after the second connecting portion 834 is connected to the third connecting portion 8121, the second housing 83 can be fixed to the bracket 81.

    [0122] It should be noted that by providing the first sub-plate 8331 and the blocking portion 8332, during the process of opening or closing the second opening 832, the second snap-fit portion 833 can rotate in the first hole 8134 around a first axis (referring to the direction X as shown in FIG. 11), such that the second snap-fit portion 833 drives the second housing 83 to rotate between a first position and a second position.

    [0123] With reference to FIG. 11, in the first position, the bracket 81 closes the second opening 832, and the blocking portion 8332 is in contact with the side of the fixing portion 813 away from the second housing 83.

    [0124] With reference to FIG. 12, in the second position, the bracket 81 opens the second opening 832, and the blocking portion 8332 is separated from the side of the fixing portion 813 away from the second housing 83.

    [0125] Here, the direction of the first axis is perpendicular to the thickness direction of the fixing portion 813, and is parallel to a plane where the first sub-opening 8321 is located. In this way, when the electric reactor body 82 in the second cavity 831 is checked or repaired for a short time, the second housing 83 may not be separated from the bracket 81, and thus the second housing 83 can be quickly connected to the bracket 81 after the electric reactor body 82 is checked or repaired.

    [0126] For example, with reference to FIG. 6 and FIG. 11, the second connecting portion 834 and the third connecting portion 8121 can be connected through the first fasteners. When the second opening 832 needs to be opened, all that is needed is to loosen the first fasteners and pull the second housing 83 in a direction away from the fixing portion 813.

    [0127] With reference to FIG. 6 and FIG. 12, the position of the first sub-plate 8331 connected to the blocking portion 8332 can be in contact with and rotate relative to the side wall of the fixing portion 813 provided with the first hole 8134 and away from the support 812, such that the second snap-fit portion 833 rotates in the first hole 8134 around the first axis until the second housing 83 rotates to the second position.

    [0128] When the second housing 83 is in the second position, the bracket 81 opens the second opening 832, and the blocking portion 8332 is separated from the side of the fixing portion 813 away from the second housing 83.

    [0129] When the second opening 832 needs to be closed, all that is needed is to rotate the second housing 83 in a direction from the second housing 83 toward the fixing portion 813. The blocking portion 8332 is rotated to enable the blocking portion 8332 to be in contact with the side of the fixing portion 813 away from the second housing 83, at the same time, the first sub-plate 8331 extends into the first hole 8134 until the second connecting portion 834 is closely attached to the third connecting portion 8121, and then the second connecting portion 834 is connected to the third connecting portion 8121 through the first fasteners. It should be noted that the axial direction of the first hole 8134 is consistent with the thickness direction of the fixing portion 813, and the first hole 8134 extends in the direction of the first axis. The size of the first hole 8134 in the direction from the connecting end 8131 to the extending end 8132 needs to meet the requirement that the first sub-plate 8331, the blocking portion 8332 and the joint between the first sub-plate 8331 and the blocking portion 8332 can pass through the first hole 8134.

    [0130] In some embodiments, in order to improve the connection reliability of the second housing 83 and the bracket 81, with reference to FIG. 9, first matching portions 835 are respectively formed on two side walls of the second housing 83 in the first direction (the direction X as shown in FIG. 9).

    [0131] Here, the first direction is perpendicular to a direction in which the electric reactor body 82 and the fixing portion 813 are arranged, and is parallel to the plane where the first sub-opening 8321 is located.

    [0132] With reference to FIG. 7, the support 812 includes two first mounting portions 8122 spaced apart in the first direction, openings of the first mounting portions 8122 face the second housing 83, the two first mounting portions 8122 respectively correspond to the two first matching portions 835, and each first matching portion 835 is snap-fitted in the corresponding first mounting portion 8122.

    [0133] Thus, the two first matching portions 835 can be limited by the two first mounting portions 8122, thereby improving the connection firmness of the second housing 83 and the bracket 81.

    [0134] For example, the first matching portions 835 can be snap-fit sheets or snap-fit rods. The first mounting portions 8122 can be disposed on the side surface of a bottom wall of the support 812 away from the base 11.

    [0135] In some embodiments, the two first mounting portions 8122 can also be formed in other manners.

    [0136] For example, with reference to FIG. 15 and FIG. 17A, a third sub-plate 8123 (for example, a support plate) can be disposed on the bottom wall of the support 812. Then third snap-fit sub-portions (for example, protrusions and snap-fit blocks) 8124 are respectively disposed on the side surface of the third sub-plate 8123 close to the first heat exchanger 3 and an outer wall surface of the side wall of the support 812 away from the first heat exchanger 3.

    [0137] For another example, with reference to FIG. 17B, stamping can be performed on the bottom wall of the support 812 in a direction from the bracket 81 to the base 11, so as to form a third sub-plate 8123 on the side of the bottom wall of the support 812 close to the base 11. Then a third snap-fit sub-portion 8124 is disposed on the side surface of the third sub-plate 8123 close to the first heat exchanger 3, and a third snap-fit sub-portion 8124 is also disposed on the side surface of the support 812 away from the first heat exchanger 3. Thus, two third snap-fit sub-portions 8124 spaced apart in the first direction can be formed on the support 812.

    [0138] Then, the first mounting portions 8122 can be formed on the third snap-fit sub-portions 8124. In addition, in a direction from the fixing portion 813 to the electric reactor body 82, the first mounting portions 8122 can penetrate through the third snap-fit sub-portions 8124. Thus, when the second housing 83 rotates from the second position to the first position around the first axis, the first matching portions 835 can be conveniently snap-fitted into the first mounting portions 8122. It should be noted that with reference to FIG. 11, FIG. 13 and FIG. 15, to facilitate the snap-fitting of the first matching portions 835 into the first mounting portions 8122, in the direction from the fixing portion 813 to the electric reactor body 82, the distance between two wall surfaces of each first mounting portion 8122 increases. For example, the distance between the two wall surfaces at the end of each first mounting portion 8122 away from the fixing portion 813 is greater than the distance between the two wall surfaces at the end of the first mounting portion 8122 close to the fixing portion 813.

    [0139] Thus, the openings at the ends of the first mounting portions 8122 away from the fixing portion 813 can be large, and the first matching portions 835 can be more smoothly assembled into the first mounting portions 8122, thereby improving the assembly efficiency of the first matching portions 835 and the first mounting portions 8122.

    [0140] In some embodiments, the bracket 81 can be fixedly connected to the base 11 through fasteners such as screws, bolts and nuts, can also be fixedly connected to the base 11 in a snap-fitted manner, and can also be fixedly connected to the base 11 in the snap-fitted manner and through the fasteners.

    [0141] In some embodiments, with reference to FIG. 7, the bracket 81 includes a first connecting portion 815, and the first connecting portion 815 is located on the side of the support 812 close to the first heat exchanger 3. For example, the first connecting portion 815 is connected to the side wall of the support 812 close to the first heat exchanger 3.

    [0142] In some embodiments, with reference to FIG. 7, the bracket 81 further includes a fifth connecting portion 816, and the fifth connecting portion 816 is located on the side of the support 812 away from the first heat exchanger 3. For example, the fifth connecting portion 816 is connected to the side wall of the side of the support 812 away from the first heat exchanger 3.

    [0143] The fifth connecting portion 816 is connected to the base 11 through third fasteners. For example, the fifth connecting portion 816 can be a connecting plate, and the third fasteners can be bolts and nuts, screws and the like.

    [0144] In some embodiments, the mobile air conditioner further includes a first snap-fit portion 10, and the first snap-fit portion 10 is located between the electric motor 9 and the first heat exchanger 3.

    [0145] For example, with reference to FIG. 2, FIG. 17A and FIG. 18, the first snap-fit portion 10 is disposed on the base 11 and located between the support 812 and the first heat exchanger 3. At least part of the electric motor 9 is located in the first avoidance portion 811 of the support 812, such that the first snap-fit portion 10 is located between the electric motor 9 and the first heat exchanger 3.

    [0146] With reference to FIG. 19, the first snap-fit portion 10 includes an abutting portion 101 and an elastic portion 102. The abutting portion 101 and the elastic portion 102 are respectively disposed on the base 11, the elastic portion 102 includes a first limiting portion 1021, and the first limiting portion 1021 is located on the side of the abutting portion 101 away from the base 11.

    [0147] The abutting portion 101 abuts against the side of the first connecting portion 815 close to the base 11, and the first limiting portion 1021 abuts against the side of the first connecting portion 815 away from the base 11.

    [0148] It should be noted that the elastic portion 102 has elasticity, and under the action of the elasticity of the elastic portion 102 itself, the elastic portion 102 can move (for example, swing) between the first heat exchanger 3 and the support 812.

    [0149] During the process of mounting the support 812 to the base 11, the first connecting portion 815 can push the elastic portion 102 to move close to the first heat exchanger 3 until the side of the first connecting portion 815 close to the base 11 abuts against the abutting portion 101, and the elastic portion 102 resets under the action of its own elasticity, such that the first limiting portion 1021 abuts against the side of the first connecting portion 815 away from the base 11, thereby snap-fitting the first connecting portion 815 with the first snap-fit portion 10.

    [0150] Thus, by snap-fitting the first connecting portion 815 with the first snap-fit portion 10, the assembly efficiency of the first connecting portion 815 and the base 11 can be improved, thereby improving the assembly efficiency of the bracket 81 and the base 11. Besides, the situation that the bracket 81 is inconveniently connected to the base 11 due to the small space between the bracket 81 and the first heat exchanger 3 can also be avoided.

    [0151] It should be noted that the abutting portion 101 can be a plurality of abutting blocks or abutting plates spaced apart in a penetrating direction of the avoidance groove, and can also be an abutting rib extending in the penetrating direction of the avoidance groove.

    [0152] The first snap-fit portion 10 includes one or more elastic portions 102. Under the condition that the first snap-fit portion 10 includes a plurality of elastic portions 102, the plurality of elastic portions 102 can be spaced apart in the penetrating direction of the avoidance groove. The first connecting portion 815 can be a connecting plate or a connecting rod.

    [0153] In some embodiments, in order to improve the assembly reliability of the first connecting portion 815 and the first snap-fit portion 10, with reference to FIG. 7, the first connecting portion 815 includes second limiting portions 8151 (for example, limiting notches), and the elastic portions 102 pass through the second limiting portions 8151.

    [0154] With reference to FIG. 7 and FIG. 19, when the first limiting portion 1021 and the abutting portion 101 respectively abut against the first connecting portion 815, at least parts of the elastic portions 102 are located in the limiting notches 8151. Thus, the elastic portions 102 can be limited by the limiting notches 8151 in the first direction.

    [0155] Thus, the elastic portions 102 can be limited by the second limiting portions 8151 in the penetrating direction of the avoidance groove, thereby reducing the movement (for example, sliding) of the first connecting portion 815 and the support 812 in the penetrating direction of the first avoidance portion 811, and facilitating the improvement of the fixing reliability of the support 812 and the base 11.

    [0156] In some embodiments, with reference to FIG. 7, a first bent portion 8152 is formed at the end of the first connecting portion 815 close to the first heat exchanger 3, and the first bent portion 8152 is bent in a direction of the first connecting portion 815 away from the base 11.

    [0157] Thus, when the support 812 is mounted, if the support 812 collides with or scratches the first heat exchanger 3, by disposing the first bent portion 8152, the contact area between the first bent portion 8152 and the first heat exchanger 3 can be enlarged, thereby protecting the first heat exchanger 3.

    [0158] In some embodiments, by snap-fitting the first connecting portion 815 with the first snap-fit portion 10, and by fixing the fifth connecting portion 816 to the base 11, two ends of the bracket 81 in the direction in which the first heat exchanger 3 and the second air duct shell 6 are arranged can be fixed to the base 11, thereby fixing the bracket 81 to the base 11 more firmly. Besides, all that is needed is to mount the third fasteners on the fifth connecting portion 816, such that the number of the third fasteners can be reduced, thereby improving the fixing efficiency of the bracket 81.

    [0159] In addition, the fixing portion 813 can also be connected to the first housing 12, such that the fixing firmness of the support 812 can be improved, and the support strength of the fixing portion 813 for the electric reactor body 82 can also be improved.

    [0160] For example, with reference to FIG. 2, the mobile air conditioner further includes the support rod 125, the support rod 125 is disposed on the inner wall of the first housing 12, and the fixing portion 813 can be fixed to the support rod 125. For example, the fixing portion 813 can be connected to the support rod 125 in a manner such as welding, riveting or screw connection.

    [0161] In some embodiments, when the bracket 81 is connected to the base 11, in order to enable the elastic portion 102 of the first snap-fit portion 10 to quickly and accurately extend into the second limiting portion 8151, with reference to FIG. 7, the first connecting portion 815 includes first positioning holes 8153. With reference to FIG. 19, the base 11 includes first positioning columns 111.

    [0162] In some embodiments, the first positioning columns 111 are located between the electric motor 9 and the first heat exchanger 3 and pass through the first positioning holes 8153. Thus, by enabling the first positioning columns 111 to pass through the first positioning holes 8153, the elastic portion 102 can be quickly aligned with the second limiting portion 8151 on the first connecting portion 815, thereby increasing the snap-fitting speed of the first snap-fit portion 10 and the first connecting portion 815, and then improving the connection efficiency of the first snap-fit portion 10 and the first connecting portion 815.

    [0163] It should be noted that the first connecting portion 815 includes a plurality of first positioning columns 111, the base 11 includes a plurality of first positioning holes 8153, the plurality of first positioning columns 111 and the plurality of first positioning holes 8153 are respectively spaced apart in the penetrating direction (for example, the third direction) of the first avoidance portion 811, and each first positioning column 111 penetrates into the corresponding first positioning hole 8153.

    [0164] In addition, in order to enable mounting holes in the fifth connecting portion 816 allowing the third fasteners to pass through with to be quickly aligned with mounting holes in the base 11 allowing the third fasteners to pass through, with reference to FIG. 7, the fifth connecting portion 816 includes second positioning holes 8161. With reference to FIG. 18, the base 11 includes second positioning columns 112.

    [0165] In some embodiments, the second positioning columns 112 are located on the side of the first avoidance portion 811 away from the first heat exchanger 3 and pass through the second positioning holes 8161. Thus, by enabling the second positioning columns 112 to pass through the second positioning holes 8161, the mounting holes of the fifth connecting portion 816 can be quickly aligned with the mounting holes of the base 11, thereby conveniently passing the first fasteners into the mounting holes, and then improving the connection efficiency of the first matching portion 835 and the fifth connecting portion 816.

    [0166] The base 11 includes a plurality of second positioning columns 112, the fifth connecting portion 816 includes a plurality of second positioning holes 8161, the plurality of second positioning columns 112 and the plurality of second positioning holes 8161 are respectively spaced apart in the penetrating direction (for example, the third direction Y) of the first avoidance portion 811, and each second positioning column 112 penetrates into the corresponding second positioning hole 8161.

    [0167] In some embodiments, the electric control box 7 is disposed in the first housing, and the electric control board 74 is disposed in the electric control box 7, thereby protecting the electric control board 74 by the electric control box 7.

    [0168] With reference to FIG. 2, the electric control box 7 can be fixedly connected to the first air duct shell 2. For example, the electric control box 7 can be connected to the first air duct shell 2 through riveting, snap-fitting, or fasteners such as bolts and screws.

    [0169] For example, the mobile air conditioner further includes fourth fasteners. With reference to FIG. 20, connecting columns 22 are disposed on the side wall of the first air duct shell 2 close to the first heat exchanger 3, and a threaded hole is formed in each connecting column 22. With reference to FIG. 21, the electric control box 7 includes fourth holes 71 (for example, connecting holes), and the fourth fasteners pass through the fourth holes 71 so as to be in threaded connection with the connecting columns 22. For example, the fourth fasteners can be bolts, screws and the like.

    [0170] With reference to FIG. 22A and FIG. 26, the electric control box 7 includes a box body 72 and a cover 73. A box cavity 711 is formed in the box body 72, and one side of the box cavity 711 is open to form a third opening. The cover 73 is disposed at the third opening and configured to open or close the box cavity 711. With reference to FIG. 32, when the electric control board 74 is in an operating state, the cover 73 closes the third opening, such that the electric control board 74 can be protected by the cover 73 and the box body 72.

    [0171] Fifth connecting portions 722 (for example, connecting lugs) are disposed on the side of the box body 72 close to the first air duct shell 2, and each fifth connecting portion 722 includes a fourth hole 71.

    [0172] Thus, the electric control box 7 is fixedly connected to the first air duct shell 2 through the fourth fasteners, the connection firmness of the first air duct shell 2 can be ensured, and the electric control box 7 can be conveniently mounted and dismounted.

    [0173] In some embodiments, in order to fix the electric control box 7 more firmly, with reference to FIG. 20, a support portion 31 is disposed on the side of the first heat exchanger 3 close to the first air duct shell 2, and the support portion 31 is in contact with the side wall of the electric control box 7 away from the first air duct shell 2. Thus, after the electric control box 7 is connected to the first air duct shell 2, the electric control box 7 can be supported by the support portion 31, thereby reducing the shaking of the electric control box 7 caused by vibration of the mobile air conditioner during the operation process, and improving the connection stability between the electric control box 7 and the first air duct shell 2.

    [0174] Here, the support portion 31 can be a side wall on the side of the first heat exchanger 3 close to the first air duct shell 2, and can also be a platy support member, a blocky support member and a support frame disposed on the side of the first heat exchanger 3 close to the first air duct shell 2.

    [0175] In this case, when the electric control box 7 is mounted, the electric control box 7 needs to be placed on the support portion 31, and then the electric control box 7 is pushed between the first heat exchanger 3 and the first air duct shell 2 in the penetrating direction of the avoidance groove.

    [0176] During the above process, in order to push the electric control box 7 more conveniently, with reference to FIG. 23, the electric control box 7 further includes a plurality of second support ribs 723, and the plurality of second support ribs 723 can be spaced apart on an outer wall surface of the box body 72 of the electric control box 7.

    [0177] For example, the second support ribs 723 can be disposed on the outer wall surface of the electric control box 7 close to the support portion 31. Thus, during the process that the electric control box 7 is pushed to be mounted, the contact area between the second support ribs 723 and the support portion 31 can be reduced, thereby reducing the friction force between the electric control box 7 and the support portion 31, and improving the mounting efficiency of the electric control box 7.

    [0178] Besides, with reference to FIG. 20, the second air duct shell 6 is connected to the side of the first heat exchanger 3 away from the electric reactor assembly 8, and is located on the side of the first air duct shell 2 close to the base 11.

    [0179] In some embodiments, with reference to FIG. 21, a second limiting member 62 is disposed on the side wall of the second air duct shell 6 close to the first air duct shell 2, a first limiting member 23 is disposed on the side of the first air duct shell 2 close to the base 11, and the electric control box 7 is located between the second limiting member 62 and the first limiting member 23. For example, the second limiting member 62 and the first limiting member 23 can be platy limiting members, limiting rods or limiting blocks. Thus, the electric control box 7 can be limited, thereby reliably mounting the electric control box 7.

    [0180] It should be noted that during the process that the electric control box 7 is pushed, the second limiting member 62 and the first limiting member 23 can limit the two sides of the electric control box 7 in the direction in which the first heat exchanger 3 and the second air duct shell 6 are arranged, thereby mounting the electric control box 7.

    [0181] Besides, by limiting the electric control box 7 by the second limiting member 62 and the first limiting member 23, such that the fourth holes 71 of the electric control box 7 are conveniently aligned with threaded holes of the first air duct shell 2, thereby facilitating the connection of the electric control box 7 and the first air duct shell 2.

    [0182] In addition, after the electric control box 7 is mounted, the second limiting member 62 and the first limiting member 23 can also reduce the shaking of the electric control box 7 in the direction in which the first heat exchanger 3 and the second air duct shell 6 are arranged, thereby protecting the electric control box 7.

    [0183] In some embodiments, with reference to FIG. 21, a first guiding portion 231 is formed on the side surface of the first limiting member 23 close to the electric control box 7, and the first guiding portion 231 extends in the third direction (for example, the direction Y in FIG. 21). Here, the third direction is perpendicular to the reference plane.

    [0184] With reference to FIG. 22A, a sliding portion 75 is disposed on the side wall of the electric control box 7 close to the first limiting member 23, and the sliding portion 75 is located on the side surface of the first guiding portion 231 away from the base 11 and can slide on the first guiding portion 231 in the third direction. Thus, the sliding process of the electric control box 7 in the third direction can be guided, thereby enabling the electric control box 7 to smoothly enter between the first heat exchanger 3 and the first air duct shell 2, and also improving the mounting efficiency of the electric control box 7.

    [0185] For example, the first guiding portion 231 can be a guiding plate or a guiding rail. The sliding portion 75 can be a side wall of the electric control box 7, and can also be a protruding block or a sliding plate disposed on the side wall of the electric control box 7.

    [0186] In some embodiments, with reference to FIG. 22A and FIG. 26, when the cover 73 of the electric control box 7 closes the third opening of the box cavity 711, the cover 73 can be connected to the box body 72 through fasteners such as bolts and nuts, screws and the like.

    [0187] With reference to FIG. 22A, the electric control box 7 includes fourth connecting portions 724. The fourth connecting portions 724 are located on one side of the box body 72 in the second direction (for example, the direction Z in FIG. 22A). With reference to FIG. 22A and FIG. 23, the electric control box 7 further includes third snap-fit portions 725. The third snap-fit portions 725 are located on the other side of the box body 72 opposite to said side in the second direction. Here, the second direction is parallel to the plane where the third opening of the box cavity 711 is located.

    [0188] With reference to FIG. 22A, second holes 731 (for example, inserting holes) are formed at one end of the cover 73 in the second direction, and the fourth connecting portions 724 are matched with the second holes 731. With reference to FIG. 23 and FIG. 25, third holes 732 (for example, snap-fit holes) are formed at the other end of the cover 73 in the second direction.

    [0189] In some embodiments, the cover 73 can switch between a third position for closing the third opening and a fourth position for opening the third opening.

    [0190] In the third position, with reference to FIG. 22A and FIG. 28, under the condition that the cover 73 closes the third opening, the fourth connecting portions 724 pass through the second holes 731 and can prevent the cover 73 from moving in a direction away from the box body 72. Besides, with reference to FIG. 23, the third snap-fit portions 725 are snap-fitted with the third holes 732.

    [0191] Thus, when the third opening is closed, all that is needed is to place the cover 73 at the third opening, enable the fourth connecting portions 724 to pass through the second holes 731, and enable the third snap-fit portions 725 to be snap-fitted with the third holes 732. Such connection manner can avoid sequential fastening of a plurality of bolts, thereby simplifying the connecting process of the cover 73 and the box body 72, and improving the assembly efficiency of the electric control box 7.

    [0192] In the fourth position, with reference to FIG. 24, under the condition that the cover 73 opens the third opening, the third snap-fit portions 725 are separated from the third holes 732. In this case, the fourth connecting portions 724 can completely exit from the second holes 731, and can still be partially located in the second holes 731.

    [0193] For example, during the process that the cover 73 opens the third opening, the cover 73 can be pulled in a direction of the cover 73 away from the box body, such that the third snap-fit portions 725 exit from the third holes 732, in this case, the fourth connecting portions 724 can still extend into the second holes 731, and the second holes 731 rotate relative to the fourth connecting portions 724 around the first axis (the first axis can extend in the direction X in FIG. 24), thereby opening the cover 73. Here, in a direction perpendicular to the axes of the second holes 731, the sizes of the second holes 731 of the cover 73 need to be greater than the sizes of the fourth connecting portions 724. Thus, when the third snap-fit portions 725 exit from the third holes 732, the fourth connecting portions 724 can move in the second holes 731, such that the fourth connecting portions 724 can rotate relative to the second holes 731 around a second axis (for example, the direction X as shown in FIG. 24) within a predetermined range. The second axis is parallel to the first axis.

    [0194] Thus, when components in the box cavity 711 are checked or repaired for a short time, parts of the fourth connecting portions 724 can be located in the second holes 731, such that after the components in the box cavity 711 are checked or repaired, the cover 73 can be rotated in a direction of the cover 73 close to the box body 72, then the cover 73 can close the third opening (also referred to as the box opening) of the box cavity 711, and the cover 73 is connected to the box body 72. If the components in the box cavity 711 are repaired for a long time, the fourth connecting portions 724 can completely exit from the second holes 731, such that the cover 73 is disengaged from the box body 72, thereby conveniently repairing the components in the box cavity 711.

    [0195] In addition, the electric control box 7 includes a plurality of fourth connecting portions 724 (also referred to as the box connecting portions), and the cover 73 includes a plurality of second holes 731, in this case, the plurality of fourth connecting portions 724 and the plurality of second holes 731 (also referred to as through holes) are respectively spaced apart in the direction of the second axis, and each fourth connecting portion 724 can pass through the corresponding second hole 731.

    [0196] The electric control box 7 includes a plurality of third snap-fit portions 725 (also referred to as box snap-fit portions), and the cover 73 includes a plurality of third holes 732, in this case, the plurality of third snap-fit portions 725 and the plurality of third holes 732 (also referred to as snap-fit holes) are respectively spaced apart in the direction of the second axis, and each third snap-fit portion 725 can be snap-fitted into the corresponding third hole 732.

    [0197] In some embodiments, under the condition that the cover 73 closes the third opening, the axial directions of the second holes 731 can be perpendicular to the plane where the third opening of the box cavity is located. In this case, in order to enable the fourth connecting portions 724 to prevent the cover 73 from moving in the direction away from the box body 72, the fourth connecting portions 724 can be configured as L-shaped rods or L-shaped plates.

    [0198] For example, with reference to FIG. 37, each fourth connecting portion 724 includes a fourth sub-plate 7121 and a fifth sub-plate 7122, the fourth sub-plate 7121 is connected to the box body 72, the fifth sub-plate 7122 is connected to the fourth sub-plate 7121, and the fourth sub-plate 7121 is perpendicular to the fifth sub-plate 7122. When the cover 73 closes the third opening, the fourth sub-plates 7121 pass through the second holes 731, and the fifth sub-plates 7122 are located on the side of the cover 73 away from the box body 72, so as to prevent the cover 73 from moving in the direction away from the box body 72.

    [0199] In some embodiments, under the condition that the cover 73 closes the third opening, the axial directions of the second holes 731 can also be consistent with the second direction.

    [0200] For example, with reference to FIG. 29, the cover 73 includes a cover body 733 and a second sub-plate 734 (for example, an inserting plate). The cover body 733 is disposed at the third opening, one end of the second sub-plate 734 is connected to one end of the cover body 733 in the second direction, and the other opposite end of the second sub-plate 734 is located on the side of the cover body 733 close to the box body 72; and the second holes 731 are formed in the second sub-plate 734 and extend in the second direction.

    [0201] In this case, the fourth connecting portions 724 can be inserting rods, inserting plates or inserting blocks.

    [0202] The axial directions of the second holes 731 are consistent with the second direction, such that after the fourth connecting portions 724 pass through the second holes 731, the hole walls of the second holes 731 can be limited in the direction perpendicular to the axial directions of the second holes 731, thereby preventing the cover 73 from moving in the direction away from the box body 72, and connecting the cover 73 to the box body 72.

    [0203] Besides, the third holes 732 are formed in the other end of the cover body 733 in the second direction. After the fourth connecting portions 724 pass through the second holes 731 and the third snap-fit portions 725 are snap-fitted with the third holes 732, the cover 73 can be fixed to the box body 72, such that the cover 73 closes the third opening.

    [0204] In some embodiments, under the condition that the cover 73 closes the third opening, the axial directions of the third holes 732 can be perpendicular to the plane where the third opening is located. In this case, the third snap-fit portions 725 can be snap-fit blocks or snap-fit hooks having elasticity, such that the third snap-fit portions 725 can abut against the hole walls of the third holes 732 by means of the elasticity of the third snap-fit portions 725, thereby snap-fitting the third snap-fit portions 725 with the third holes 732.

    [0205] For example, the third snap-fit portions 725 are the snap-fit blocks, and in the direction perpendicular to the axial directions of the third holes 732, the sizes of the third snap-fit portions 725 are greater than the sizes of the third holes 732, such that when the third snap-fit portions 725 are snap-fitted with the third holes 732, the third snap-fit portions 725 extend into the third holes 732, then the hole walls of the third holes 732 extrude the third snap-fit portions 725, the third snap-fit portions 725 are elastically deformed, the third snap-fit portions 725 abut against the hole walls of the third holes 732 under the elastic action, and then the third snap-fit portions 725 are snap-fitted with the third holes 732.

    [0206] Under the condition that the cover 73 closes the third opening, the axial directions of the third holes 732 can also be consistent with the second direction.

    [0207] For example, with reference to FIG. 29 and FIG. 30, the cover body 733 includes a covering portion 7331 and a fourth snap-fit portion 7332 (also referred to as cover-body snap-fit portion). The covering portion 7331 is configured to open or close the third opening, and the second sub-plate 734 is connected to one end of the covering portion 7331 in the second direction; and one end of the fourth snap-fit portion 7332 is connected to the other end of the covering portion 7331 in the second direction, and the other opposite end of the fourth snap-fit portion 7332 is located on the side of the covering portion 7331 close to the box body 72.

    [0208] The third holes 732 are formed in the fourth snap-fit portion 7332, and the axial directions of the third holes 732 are consistent with the second direction. Thus, after the third snap-fit portions 725 are snap-fitted with the third holes 732, the cover 73 can be fixed to the box body 72, and the cover 73 can be further prevented from moving in the direction away from the box body 72, thereby enhancing the connection firmness of the third snap-fit portions 725 and the third holes 732, and then enhancing the connection firmness of the box body 72 and the cover 73.

    [0209] For example, the third snap-fit portions 725 can be snap-fit blocks, snap-fit rods or snap-fit sheets. The fourth snap-fit portion 7332 can be a snap-fit sheet.

    [0210] It should be noted that in order to facilitate the third snap-fit portions 725 to exit from the third holes 732, at least one of the third snap-fit portions 725 and the fourth snap-fit portion 7332 can be elastic. Thus, when the cover 73 opens the third opening, the fourth snap-fit portion 7332 can be pulled in the direction of the fourth snap-fit portion 7332 away from the second sub-plate 734, or the third snap-fit portions 725 are extruded in the direction of the fourth snap-fit portion 7332 close to the second sub-plate 734, such that the third snap-fit portions 725 exit from the third holes 732.

    [0211] The fourth snap-fit portion 7332 being elastic is mainly taken as an example for explanation below.

    [0212] On this basis, with reference to FIG. 27, each third snap-fit portion 725 includes a first snap-fit sub-portion 7251 (for example, a snap-fit block), and the end of the first snap-fit sub-portion 7251 away from the third opening extends into the third hole 732, so as to be snap-fitted with the third hole 732.

    [0213] A guiding inclined surface 72511 is formed on the side of the first snap-fit sub-portion 7251 away from the third opening, and in the direction from the cover 73 to the box body 72, a distance between the guiding inclined surface 72511 and the side surface of the fourth snap-fit portion 7332 away from the second sub-plate 734 decreases. That is, compared with the end of the guiding inclined surface 72511 away from the covering portion 7331, the end of the guiding inclined surface 72511 close to the covering portion 7331 is closer to the third opening of the box cavity 711.

    [0214] Thus, during the process that the third snap-fit portions 725 are snap-fitted with the third holes 732, the fourth snap-fit portion 7332 first comes into contact with the guiding inclined surface 72511 and gets close to the box body 72 along the guiding inclined surface 72511, thereby enabling the guiding inclined surface 72511 to play a role in guiding the assembly of the fourth snap-fit portion 7332, and then improving the assembly efficiency of the third snap-fit portions 725 and the third holes 732.

    [0215] It should be noted that during the process that the fourth snap-fit portion 7332 gets close to the box body 72 along the guiding inclined surface 72511, the snap-fit portion 7332 extrudes the guiding inclined surface 72511, such that under the reaction force of the guiding inclined surface 72511 and under the action of the elasticity of the fourth snap-fit portion 7332, the fourth snap-fit portion 7332 moves towards the third opening of the box cavity 711 until the third snap-fit portions 725 extend into the third holes 732, then the fourth snap-fit portion 7332 does not abut against the third snap-fit portions 725, the fourth snap-fit portion 7332 is reset, and the third snap-fit portions 725 are snap-fitted with the third holes 732.

    [0216] Besides, in order to enable the cover 73 to open the third opening of the box cavity 711 conveniently, in some embodiments, with reference to FIG. 29, the cover 73 further includes push-pull portions 735 (for example, push-pull members). The push-pull portions 735 are connected to the end of the cover body 733 away from the second sub-plate 734, such that the push-pull portions 735 are pulled or pushed to drive the cover 73 to rotate around the first axis, and the cover 73 can conveniently open or close the third opening.

    [0217] For example, with reference to FIG. 29 and FIG. 31, at least parts of the push-pull portions 735 are located on the side of the fourth snap-fit portion 7332 away from the second sub-plate 734, such that the push-pull portions 735 can be conveniently held.

    [0218] The push-pull portions 735 can be connected to the fourth snap-fit portion 7332, and can also be connected to the covering portion 7331. The push-pull portions 735 can be push-pull plates or push-pull rods.

    [0219] In some embodiments, with reference to FIG. 29, the push-pull portions 735 extend to the outer side of the cover body 733 in the first direction (for example, the direction X in FIG. 29). For example, the cover 73 further includes a plurality of push-pull portions 735, and the plurality of push-pull portions 735 are respectively fixedly connected to the fourth snap-fit portion 7332.

    [0220] With reference to FIG. 29, one push-pull portion 735 is connected to one side surface of the fourth snap-fit portion 7332 in the first direction, and the other push-pull portion 735 is connected to the other side surface of the fourth snap-fit portion 7332 in the first direction.

    [0221] Here, the first direction is perpendicular to the second direction and parallel to the plane where the third opening of the box cavity 711 is located.

    [0222] Thus, when the cover 73 opens the third opening of the box cavity 711, by pulling the two push-pull portions 735 in the direction of the fourth snap-fit portion 7332 away from the second sub-plate 734, the third snap-fit portions 725 can exit from the third holes 732, then at least one of the two push-pull portions 735 is pulled in the direction of the cover 73 away from the box body 72, and the cover 73 can be driven to rotate, thereby opening the third opening of the box cavity 711.

    [0223] Besides, by disposing the two push-pull portions 735 on the fourth snap-fit portion 7332, when the fourth snap-fit portion 7332 is pulled, the third snap-fit portions 725 can more conveniently exit from the third holes 732, thereby more conveniently rotating the cover 73. In addition, by means of the two push-pull portions, when the fourth snap-fit portion 7332 is pulled, the fourth snap-fit portion 7332 can be relatively uniformly stressed, such that the third snap-fit portions 725 can more smoothly exit from the third holes 732.

    [0224] In some embodiments, with reference to FIG. 32 and FIG. 33, the mobile air conditioner further includes a magnetic ring 20. The magnetic ring 20 is disposed in the box cavity 711. In order to facilitate wiring of connecting lines connected to the magnetic ring 20, a plurality of first support ribs 7211 spaced apart are formed on the side wall of the box cavity 711.

    [0225] For example, with reference to FIG. 34, the magnetic ring 20 is disposed on the sides of the plurality of first support ribs 7211 away from the side wall of the box cavity 711, and the connecting lines of the magnetic ring 20 are located among the plurality of first support ribs 7211.

    [0226] Thus, when the magnetic ring 20 is mounted, the magnetic ring 20 is supported through the plurality of first support ribs 7211, such that a gap exists between the magnetic ring 20 and the side wall of the box cavity 711, the connecting lines connected to the magnetic ring 20 can be arranged in the space between the magnetic ring 20 and the side wall of the box cavity 711, and the connecting lines are located among the plurality of first support ribs 7211.

    [0227] Thus, the mutual interference between the magnetic ring 20 and the connecting lines can be avoided, the connecting lines can be arranged relatively neatly, and the connecting lines can also be protected.

    [0228] Besides, in order to ensure the mounting stability of the magnetic ring 20 in the box cavity 711, with reference to FIG. 32 and FIG. 34, a plurality of limiting portions 7212 are formed in the box cavity 711. The plurality of limiting portions 7212 are spaced apart in the circumferential direction of the magnetic ring 20, and the magnetic ring 20 is located among the plurality of limiting portions 7212.

    [0229] The magnetic ring 20 is mounted in the position close to the electric control board 74, such that by means of the plurality of limiting portions 7212, the magnetic ring 20 can be limited among the plurality of limiting portions 7212, and the shaking of the magnetic ring 20 caused during the operating process of the mobile air conditioner can be reduced, thereby reducing the possibility of collisions of the magnetic ring 20 with the electric control board 74, and then facilitating the prolonging of the service life of the magnetic ring 20 and the electric control board 74.

    [0230] It should be noted that the magnetic ring 20 can be disposed on a corner of the box cavity 711, thus, with reference to FIG. 32, the plurality of limiting portions 7212 can be a first side wall 7213 and a second side wall 7214 of the box cavity 711, and arc-shaped plates or limiting rods spaced apart from the first side wall 7213 and the second side wall 7214. For example, the first side wall 7213 and the second side wall 7214 are adjacent to each other, and the plurality of limiting portions 7212 are respectively connected to one of the first side wall 7213 and the second side wall 7214 that is provided with the first support ribs 7211.

    [0231] The magnetic ring 20 can also be disposed at other positions of the box cavity 711, such that the plurality of limiting portions 7212 can also be a plurality of arc-shaped limiting plates and limiting rods spaced apart.

    [0232] In some embodiments, in order to conveniently mount the electric control board 74 and the magnetic ring 20 in the box cavity 711, with reference to FIG. 32, the box body 72 includes a third housing 726 and a fourth housing 727.

    [0233] With reference to FIG. 35 and FIG. 36, a first sub-cavity 7161 and a third sub-opening 7162 (also referred to as first sub-cavity opening) are formed in the third housing 726, and the third sub-opening 7162 is formed in the side wall of the third housing 726 close to the cover 73. A second sub-cavity 7171 and a fourth sub-opening 7172 (also referred to as second sub-cavity opening) are formed in the fourth housing 727, the fourth sub-opening 7172 is formed in the side wall of the fourth housing 727 close to the cover 73, and the third housing 726 is connected to the fourth housing 727, such that the third sub-opening 7162 and the fourth sub-opening 7172 form the third opening of the box cavity 711.

    [0234] The fourth housing 727 is located on one side of the third housing 726 in the first direction, communicating openings are respectively formed in the side walls of the third housing 726 and the fourth housing 727 close to each other, and the first sub-cavity 7161 and the second sub-cavity 7171 are in communication with each other through the corresponding communicating openings, thereby forming the box cavity 711.

    [0235] That is, the third housing 726 and the fourth housing 727 are connected to form the box body 72, and the first sub-cavity 7161 and the second sub-cavity 7171 are in communication with each other to form the box cavity 711.

    [0236] For example, the third housing 726 and the fourth housing 727 can be connected through fasteners such as bolts and nuts, screws and the like, and can also be connected in a snap-fitted manner.

    [0237] The third housing 726 and the fourth housing 727 being connected in the snap-fit manner is mainly taken as an example for explanation below.

    [0238] With reference to FIG. 22B, a plurality of sixth connecting portions 7273 (for example, snap-fit plates) spaced apart in the circumferential directions of the communicating openings of the third housing 726 and the fourth housing 727 are formed on one of the third housing 726 and the fourth housing 727, and the sixth connecting portions 7273 include a plurality of fifth holes 72731 (for example, snap-fit holes).

    [0239] A plurality of second snap-fit sub-portions 7263 (for example, snap-fit protrusions and snap-fit blocks) spaced apart in the circumferential directions of the communicating openings of the third housing 726 and the fourth housing 727 are formed on the other one of the third housing 726 and the fourth housing 727, and each second snap-fit sub-portion 7263 is snap-fitted in the corresponding fifth hole 72731. For example, the plurality of sixth connecting portions 7273 can be formed on the third housing 726, and the plurality of second snap-fit sub-portions 7263 can be formed on the fourth housing 727. Alternatively, the plurality of second snap-fit sub-portions 7263 can be formed on the third housing 726, and the plurality of sixth connecting portions 7273 can be formed on the fourth housing 727.

    [0240] The second snap-fit sub-portions 7263 are snap-fitted in the fifth holes 72731, that is, the second snap-fit sub-portions 7263 extend into the fifth holes 72731, thereby limiting the second snap-fit sub-portions 7263 through the fifth holes 72731, and limiting the movement of the third housing 726 and the fourth housing 727 in the direction away from each other, so as to connecting the third housing 726 to the fourth housing 727.

    [0241] Besides, by snap-fitting the second snap-fit sub-portions 7263 with the fifth holes 72731, the assembly and disassembly of the third housing 726 and the fourth housing 727 can be facilitated, thereby facilitating mounting, repair and replacement of the components such as the electric control board 74 and the magnetic ring 20 in the box cavity 711.

    [0242] For example, the sixth connecting portions 7273 can be disposed on the inner wall of one of the third housing 726 and the fourth housing 727, and the second snap-fit sub-portions 7263 can be disposed on the inner wall of the other one of the third housing 726 and the fourth housing 727. Alternatively, the sixth connecting portions 7273 can be disposed on the outer wall of one of the third housing 726 and the fourth housing 727, and the second snap-fit sub-portions 7263 can be disposed on the outer wall of the other one of the third housing 726 and the fourth housing 727.

    [0243] Here, the axial directions of the fifth holes 72731 can be consistent with the direction in which the third housing 726 and the fourth housing 727 are arranged, and can also be perpendicular to the direction in which the third housing 726 and the fourth housing 727 are arranged.

    [0244] Herein, the sixth connecting portions 7273 being formed on the third housing 726, the second snap-fit sub-portions 7263 being formed on the fourth housing 727, and the axial directions of the fifth holes 72731 being perpendicular to the direction in which the third housing 726 and the fourth housing 727 are arranged are taken as an example for explanation.

    [0245] Here, the sixth connecting portions 7273 are connected to the outer side wall of the third housing 726, and extend, in the direction of the third housing 726 close to the fourth housing 727, to the side of the communicating openings of the fourth housing 727 away from the communicating openings of the third housing 726, the second snap-fit sub-portions 7263 are connected to the outer side wall of the fourth housing 727, and the second snap-fit sub-portions 7263 extend into the fifth holes 72731 in the direction of the fourth housing 727 close to the sixth connecting portions 7273.

    [0246] In some embodiments, in order to more smoothly snap-fit the second snap-fit sub-portions 7263 into the fifth holes 72731, with reference to FIG. 22B, a plurality of second guiding portions 7264 (for example, guiding protrusions) spaced apart in the circumferential directions of the communicating openings of the third housing 726 and the fourth housing 727 are also formed on the other one of the third housing 726 and the fourth housing 727. For example, the third housing 726 includes the plurality of sixth connecting portions 7273, and the fourth housing 727 includes the plurality of second guiding portions 7264. Alternatively, the fourth housing 727 includes the plurality of sixth connecting portions 7273, and the third housing 726 includes the plurality of second guiding portions 7264.

    [0247] Each second guiding portion 7264 includes a sixth hole (for example, a guiding hole and a snap-fit hole) 72641, the axial direction of each sixth hole 72641 is consistent with the extension direction of the sixth connecting portion 7273, and each sixth connecting portion 7273 extends into the corresponding sixth hole 72641.

    [0248] Thus, during the process that the second snap-fit sub-portions 7263 are snap-fitted with the fifth holes 72731, the sixth connecting portions 7273 can first extend into the sixth holes 72641, under the guidance of the sixth holes 72641, the fifth holes 72731 of the sixth connecting portions 7273 can smoothly move to the second snap-fit sub-portions 7263, and the second snap-fit sub-portions 7263 are snap-fitted with the fifth holes 72731, such that the second snap-fit sub-portions 7263 can be quickly aligned with the fifth holes 72731, thereby improving the assembly efficiency of the third housing 726 and the fourth housing 727.
