DETAILED DESCRIPTION

[0038] For a better understanding and implementation, the technical solutions in the embodiments of the present disclosure are clearly and completely described below in conjunction with the attached drawings of the present disclosure.

[0039] In the description of the present disclosure, it is to be noted that the terms up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside and other orientation or position relationships are based on the orientation or position relationships shown in the attached drawings. It is only intended to facilitate description of the present disclosure and simplify description, but not to indicate or imply that the referred device or element has a specific orientation, or is constructed and operated in a specific orientation. Therefore, they should not be construed as a limitation of the present disclosure.

[0040] Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are used only to describe specific embodiments and are not intended as a limitation of the disclosure.

[0041] Referring to FIGS. 1 to 12 for details, disclosed in the present disclosure is a gas system, including: a valve switch member 1, provided with a mild-flame port and a functional port; an electromagnetic valve 2, connected to the functional port of the valve switch member 1; and a burner component 6, in which the mild-flame port of the valve switch member 1 is in communication with the burner component 6 in a mild-flame state, and the electromagnetic valve 2 is opened so that both the mild-flame port and the functional port of the valve switch member 1 are in communication with the burner component 6 in a high-flame state.

[0042] It should be noted that fluid fuel used in the present gas system is preferably gas, and the use of liquefied or liquid fuels are conventional replacements in the art.

[0043] In the present embodiment, referring to FIGS. 8 to 10, the valve switch member 1 is preferable a plug valve. The valve switch member 1 is configured with a closed gear, a mild-flame gear, a functional gear and a valve switch 13 configured to be switched among the closed gear, the mild-flame gear, and the functional gear. When the valve switch 13 is switched to the mild-flame gear, the mild-flame port of the valve switch member 1 is in communication with an input port of the valve switch member 1 through a first inner channel 11. When the valve switch 13 is switched to the functional gear, both of the mild-flame port and the functional port of the valve switch member 1 are in communication with the input port of the valve switch member 1. That is, the mild-flame port of the valve switch member 1 is in communication with the input port of the valve switch member 1 through the first inner channel 11, and the functional port of the valve switch member 1 is in communication with the input port of the valve switch member 1 through the second inner channel.

[0044] When the valve switch 13 is switched to the closed gear, the fluid fuel flows into the valve switch member 1 through the input port of the valve switch member 1 and fills with the first inner channel and the second inner channel inside the valve switch member 1. The fluid fuel is retained in the first inner channel 11 and the second inner channel within the valve switch member 1 by blockage of the valve switch member 1, thereby achieving a cut-off of the supply of the fluid fuel from the gas system to the burner component 6.

[0045] When the valve switch 13 is switched to the mild-flame gear, the fluid fuel supplies to the burner component 6 through the mild-flame port of the valve switch member 1, at which the burner component 6 is in the mild-flame state and generates heat. Further, the burner component 6 is further configured with a thermocouple 8, and the valve switch member 1 is preferably configured with a switch electromagnetic valve electrically connected to the thermocouple 8. Typically, the thermocouple 8 is configured on a mild-flame output end of the burner component 6, and thermocouple 8 is a sensor that connects the ends of two metals of different materials and detects the temperature using the thermoelectric effect. A metal end of the thermocouple 8 is connected to the electromagnetic valve 2, so that the heat generated by the burner component 6 induces the thermocouple 8 on the burner component 6 to generate a high electrical potential, creating a potential difference. The switch electromagnetic valve within the valve switch member 1 is caused to be attracted, which feedbacks that the burner component 6 and its gas system are in a normal use state, so as to achieve a self-locking of the gas path.

[0046] In such an arrangement, the switch electromagnetic valve within the valve switch member 1 is cooperated with the thermocouple 8, which ensures the stability of the flow supply of the fluid fuel. Also, the switch electromagnetic valve within the valve switch member 1 is unable to keep an attracted state and is reset to close when the burner component 6 is not ignited and heat is unable to be generated to from a potential difference, at which the fluid fuel is unable to flow through the valve switch member 1, so that the fluid fuel supply is cut off in time, thereby achieving double protection by cooperating with the valve switch 13.

[0047] When the valve switch 13 is switched to the functional gear, a part of the fluid fuel is supplied to the burner component 6 through the mild-flame port of the valve switch member 1 to ensure the burner component 6 produces a mild flame and generates heat, which induces the thermocouple 8 on the burner component 6 to generate a high electrical potential, creating a potential difference. In this way, the switch electromagnetic valve within the valve switch member 1 is caused to be attracted, which feedbacks that the burner component 6 and its gas system are in a normal use state. The other part of the fluid fuel flows to the electromagnetic valve 2 through the functional port of the valve switch member 1, and the electromagnetic valve 2 is opened after receiving a corresponding instruction, so that the fluid fuel is able to flow through the electromagnetic valve 2 and be supplied to the burner component 6, at which an amount of fluid fuel supplied to the burner component 6 is greatly increased, and the burner component 6 is in a high-flame state.

[0048] In such an arrangement, free switching can be achieved between a mild-flame state and a high-flame state, i.e., free switching can be achieved between keeping warm and rapid heating of the gas system, by only utilizing the cooperation of the burner component 6, the electromagnetic valve 2, and the valve switch member 1. Compared with the gas path of the existing gas water heater, it saves one of an independent switch on the main pipe and the branch pipe, as well as the mild-flame burner and the burner component, so as to greatly simplify the number of parts and the connection under the premise of retaining a mild-flame state and a high-flame state. Also, it reduces the risk of leaks from loose connections or aging piping connections. Furthermore, it is also conducive to subsequent troubleshooting and maintenance, achieving a reduction in manufacturing costs and subsequent maintenance costs.

[0049] As a preferable implementation of the present embodiment, referring to FIG. 7 for details, the gas system further includes a temperature control element 4, in which the temperature control element 4 is electrically connected to the electromagnetic valve 2, and the temperature control element 4 is configured to detect a temperature and feedback a control instruction to the electromagnetic valve 2. The temperature control element 4 is provided with a temperature monitoring circuit 42 configured to monitor the ambient temperature in real-time. Preferably, the temperature monitoring circuit 42 adopts an RC1 circuit including a thermistor and a capacitor in conjunction with a detection element (e.g., a temperature-sensitive probe), then the actual ambient temperature is simulated by the change in the current. A variation range of the RC1 circuit herein is 0 mA to 100 mA, and the temperature range detected by the temperature monitoring circuit 42 is 100 C. to 400 C. In such an arrangement, it is known from an equal-proportional formula that the temperature monitoring circuit 42 is able to infer a 1 C. change in the ambient temperature based on every 0.2 mA change.

[0050] It should be noted that the detecting temperature range is preferably in a temperature range of 0 C. to 36 C. The detecting temperature range is within the temperature range of 0 C. to 36 C., i.e., the ambient temperature is controlled to be within temperature range of 0 C. to 36 C., which effectively ensures that the human body feels relatively comfortable. When the ambient temperature exceeds 36 C., the human body may feel that the temperature is too high, and it is prone to lead to heat and discomfort problems. When the ambient temperature is below 0 C., the ambient temperature is too low, and it is prone to lead to the risk of frostbite in the human body. The detecting temperature range is further preferably in a temperature range of 18 C. to 23 C., so as to ensure that the ambient temperature is kept in the optimal temperature range of 18 C. to 23 C.

[0051] Further, referring to FIG. 7 for details, the temperature control element 4 further includes a wireless communication circuit 41. The wireless communication circuit 41 herein is preferably a Bluetooth WiFi two-in-one circuit. Admittedly, the wireless communication circuit 41 may also be a single Bluetooth circuit, or the wireless communication circuit 41 may also be a single Wi-Fi circuit. The thermocouple 8 is electrically connected to the wireless communication circuit 41, a corresponding temperature value is able to be calculated from the potential difference by the thermocouple 8, and the temperature value is formed into a first temperature signal to be transmitted to the wireless communication circuit 41. The wireless communication circuit 41 feedbacks the first temperature signal to a terminal device by radio signals, so that the terminal device is able to display the temperature value described above in time.

[0052] In addition, the wireless communication circuit 41 is electrically connected to the temperature monitoring circuit 42, and the actual temperature of the environment is simulated to be formed into a second temperature signal to be transmitted to the wireless communication circuit 41. The wireless communication circuit 41 feedbacks the second temperature signal to the terminal device by radio signals, so that the terminal device is also able to display the actual temperature of the environment in time.

[0053] In such an arrangement, the terminal device is able to synchronize the display of the temperature value detected by the thermocouple 8 and the actual temperature of the environment, so as to enable people to clearly grasp the information of both, thereby facilitating people to make timely responses and adjustments to the gas system. Admittedly, the terminal device is also able to compare and analyze the temperature value detected by the thermocouple 8 with the actual temperature of the environment, so as to more efficiently convert the signals into a control instruction and transmit them to the temperature control element 4, thereby ultimately achieving a timely and efficient control of the electromagnetic valve 2 being opened or closed, and achieving a real-time adjustment of the ambient temperature.

[0054] It should also be noted that, referring to FIG. 7 for details, the wireless communication circuit 41 described above is also able to receive control instructions sent by the terminal device. That is, the terminal device is usually preset with a temperature parameter value. A corresponding control instruction is transmitted to the wireless communication circuit 41 to control an operation of the electromagnetic valve 2 when the second temperature signal, received by the terminal device, is not higher or not lower than the temperature parameter value. The temperature parameter value may be any one of temperature value within a temperature range of 0 C. to 36 C., and the temperature parameter value may be freely adjusted according to one's needs.

[0055] Admittedly, besides the above comparison analysis of the temperature parameter value with the second temperature signal, it is also possible to perform a comprehensive analysis for a combination of the temperature parameter value, the first temperature signal, and the second temperature signal, so as to improve the intelligence degree of the gas system, thereby more comprehensively and effectively ensuring that the ambient temperature is in an optimal temperature range.

[0056] Further, referring to FIG. 7 for details, the temperature control element 4 further includes a control circuit 43 for being electrically connected to the electromagnetic valve 2, and the control circuit 43 may be adjusted or changed according to different types of the electromagnetic valve 2. Therefore, the control instruction is received by the wireless communication circuit 41 and is transmitted to the control circuit 43, is converted by the control circuit 43 to become an operating instruction adapted to the electromagnetic valve 2, and is finally transmitted to the electromagnetic valve 2 to control the on and off of the electromagnetic valve 2.

[0057] It should also be noted that, referring to FIG. 7 for details, the aforementioned temperature control element 4 further includes a power conversion circuit 44, and the power conversion circuit 44 is configure to convert the household electricity into the power supply required by the wireless communication circuit 41. The household electricity is bucked using capacitor bucking method, and then rectified, regulated and filtered, which is able to convert an alternating current of 220V or 110V into a direct current of 5V.

[0058] In some embodiment, referring to FIG. 7 for details, the aforementioned temperature control element 4 may further include a display module 45, and the display module 45 is preferably a display screen. The display module 45 is electrically connected to the wireless communication circuit 41, and both of the first temperature signal and the second temperature signal are able to be transmitted to the display module to be displayed synchronously. The current temperature value detected by the thermocouple 8 and the actual temperature of the environment are also able to be viewed through the display module 45 of the temperature control element 4 when one is away from the terminal device. It should also be noted herein that the display module 45 may also display the preset temperature parameter value according to different designs and requirements.

[0059] Admittedly, the display module 45 may also be a control screen or a touch screen, so that one may also be able to temporarily adjust the set parameters according to the temperature value detected by the thermocouple 8 currently displayed and the actual temperature of the environment when away from the terminal device, thereby improving the convenience of controlling the gas system.

[0060] In the aforementioned gas system, not only is it possible to achieve a free switching between the mild-flame state and the high-flame state by adopting relatively few parts, which is conducive to a free switching between heating and heat preservation of the gas system, but also it is possible to analyze the current ambient temperature and the temperature value detected by the thermocouple 8, and to automatically switch between the mild-flame state and the high-flame state of the gas system based on the current ambient temperature and the temperature value detected by the thermocouple 8 to ensure that people are in a relatively appropriate ambient temperature, thereby effectively improving the comfort of the environment.

[0061] However, in a relatively spacious environment, a large amount of fluid fuel is consumed leading to a significant waste if the gas system is left in a mild-flame or high-flame state for a long period of time. Moreover, when people are active or resting at a location in a spacious environment, the gas system is unable to target the localized location in the environment for effective and rapid warming and heating.

[0062] In view of the existing problems mentioned above, disclosed by the inventors is also a further preferable solution, referring to FIGS. 1 to 6, the gas system further includes a directional valve 3, in which the directional valve 3 is provided between the burner component 6 and the valve switch member 1, and the directional valve 3 is configured to change a flow of fluid fuel into the burner component 6.

[0063] It should be noted that, the directional valve 3 is of mature prior art in the field, is a directional control valve with two or more flow patterns and two or more inlet/outlet ports, and is a valve to achieve communication, cut-off, direction change, pressure unloading, and sequential action control of fluid fuel. Directional valve 3 is categorized into such as two-position directional valves and three-position directional valves according to the number of working positions where the directional valve core stays in the directional valve 3. Alternatively, the directional valve 3 is categorized into such as two-way directional valves, three-way directional valves, four-way directional valves, and six-way directional valves according to the number of inlet/outlet ports connected to the valve body. Alternatively, the directional valve 3 is categorized into such as manual directional valves, motorized directional valves, electric directional valves, hydraulic directional valves, electro-hydraulic directional valves, and other types according to the movement mode of the directional valve core. The specific type and model of the directional valve 3 are not limited herein, and the specific model corresponding to the directional valve 3 may be selected according to the actual claims and structural design.

[0064] Preferably, the directional valve 3 is configured between the burner component 6 and the electromagnetic valve 2, i.e., the fluid fuel flows to the directional valve 3 once the electromagnetic valve 2 is opened. Utilizing a redirection function of the directional valve 3, the flow direction of the fluid fuel may be changed at an appropriate timing, so that the fluid fuel enters the burner component 6 from different positions, so as to allow the fluid fuel to be combusted and heated in the different positions of the burner component 6, and achieve a flexible change in the position of heat generation according to the needs, thereby addressing the problem that the gas system is unable to target localized positions in the environment for effective and rapid warming and heating.

[0065] Specifically, referring to FIGS. 1 to 6 for details, the directional valve 4 is provided with a first primary outlet, a second primary outlet, a first secondary outlet, a second secondary outlet, a functional input, and a mild-flame input. The functional port of the valve switch member 1 is connected to the input port of the electromagnetic valve 2 through a first pipe 51, both of the first primary outlet and the second primary outlet are in communication with the mild-flame input, both of the first secondary outlet and the second secondary outlet are in communication with the functional input, the output port of the electromagnetic valve 2 is connected to the functional input of the directional valve 3 through a second pipe 52, and the mild-flame port of the valve switch member 1 is in communication with the mild-flame input of the directional valve 3 through a third pipe 53.

[0066] The burner component 6 is provided with an NG primary port 61, an LPG primary port 62, an NG secondary port 63 corresponding to the NG primary port 61, and an LPG secondary port 65 corresponding to the LPG primary port 62, in which the term of corresponding to should be interpreted as correspondingly conducted. That is, the area covered by the mild-flame outlet of the burner component 6 is defined as a mild-flame combustion zone, and the mild-flame combustion zone is divided into a first combustion zone and a second combustion zone according to the different combustion positions of the flames. Both of the NG primary port 61 and the NG secondary port 63 are able to direct the fluid fuel to be supplied to the first combustion zone of the burner component 6, and both of the LPG primary port 62 and the LPG secondary port 65 are able to direct the fluid fuel to be supplied to the second combustion zone of the burner component 6.

[0067] Referring to FIGS. 1 to 6 for details, the NG primary port 61 is in communication with the first primary outlet of the directional valve 3 through a fourth pipe 54, the LPG primary port 62 is in communication with the second primary outlet of the directional valve 3 through a fifth pipe 55, the NG secondary port 63 is in communication with the first secondary outlet of the directional valve 3 through a sixth pipe 56, and the LPG secondary port 65 is in communication with the second secondary outlet of the directional valve 3 through a seventh pipe 57.

[0068] In such an arrangement, the fluid fuel entering the directional valve 3 is transported to the NG primary port 61 of the burner component 6 guided by the fourth pipe 54 when the directional valve 3 is switched to the NG control gear, and the fluid fuel flows through the NG primary port 61 and is supplied to the first combustion zone of the burner component 6, at which the first combustion zone of the burner component 6 is in the mild-flame state. The fluid fuel entering the directional valve 3 is transported to the LPG primary port 62 of the burner component 6 guided by the fifth pipe 55 when the directional valve 3 is switched to the LPG control gear, and the fluid fuel flows through the LPG primary port 62 and is supplied to the second combustion zone of the burner component 6, at which the second combustion zone of the burner component 6 is in the mild-flame state.

[0069] The fluid fuel entering the directional valve 3 directed by the third pipe 53 is transported to the NG primary port 61 of the burner component 6 directed by the fourth pipe 54 when the valve switch 13 of the valve switch member 1 is switched from the mild-flame gear to the functional gear and the directional valve 3 is switched to the NG control gear. Synchronously, another part of the fluid fuel entering the directional valve 3 guided by the second pipe 52 is transported to the NG secondary port 63 of the burner component 6 guided by the sixth pipe 56. Two parts of the fluid fuel are pooled and supplied to the first combustion zone of the burner component 6, at which the first combustion zone of the burner component 6 is in the high-flame state.

[0070] The fluid fuel entering the directional valve 3 guided by the third pipe 53 is transported to the LPG primary port 62 of the burner component 6 guided by the fifth pipe 55 when the valve switch 13 of the valve switch member 1 is switched from the mild-flame gear to the functional gear and the directional valve 3 is switched to the LPG control gear. Synchronously, another part of the fluid fuel entering the directional valve 3 guided by the second pipe 52 is transported to the LPG secondary port 65 of the burner component 6 guided by the seventh pipe 57. Two parts of the fluid fuel are pooled and supplied to the second combustion zone of the burner component 6, at which the second combustion zone of the burner component 6 is in the high-flame state.

[0071] It is evident that, by means of the cooperation of the directional valve 3, the electromagnetic valve 2, and the valve switch member, it is not only possible to achieve targeted heating for different locations in the environment with mild flames, but also to achieve targeted rapid heating for different locations in the environment with high flames, thereby greatly improving flexibility and precision of the temperature regulation of the gas system.

[0072] It should be noted that, the two gears of the NG control gear and the LPG control gear of the directional valve 3 are not specifically limited, as a corresponding directional valve 3 may be selected according to the type of the burner component 6.

[0073] Additionally, in other embodiments, based on the experience of those skilled in the art, the directional valve 3 may also be configured between the valve switch member 1 and the electromagnetic valve 2, which is also able to achieve the aforementioned effect of targeted mild-flame heating and high-flame rapid heating for different locations in the environment.

[0074] As a further preferable implementation of the present embodiment, referring to FIGS. 1 to 6 and 8 to 10 for details, the gas system further includes a pressure regulating valve 7, and the pressure regulating valve 7 is connected to the input port of the valve switch member 1 through an eighth pipe 58. Specifically, the pressure regulating valve 7 serves as a throttling element whose local resistance is variable, i.e., by changing a throttling area, the flow rate and the kinetic energy of the fluid are altered, resulting in a different pressure loss, so as to achieve the purpose of pressure reduction. By means of the pressure-reducing and regulating property of the pressure regulating valve 7, the pressure of the fluid fuel flowing into the pressure regulating valve 7 is reduced to the pressure set by the output of the pressure regulating valve 7, and is maintained to be transported steadily to the input port of the valve switch member 1, so that the use stability of the gas system is effectively improved.

[0075] Preferably, referring to FIGS. 11 and 12, the electromagnetic valve 2 and the valve switch member 1 are integrally molded, and the integral molding herein may optionally be replaced with a detachable connection, such as a threaded connection and a snap-fit connection. Alternatively, the integral molding may also be replaced with a welded connection or injection molding, so that the gas system is simpler in structure and requires fewer pipes and fittings for connection, thereby reducing the risk of leakage and the difficulty of investigation, as well as facilitating the assembly of the connections.

[0076] Based on the structure and connection relationship of the aforementioned gas system, provided by the inventor is also a heating apparatus applying the aforementioned gas system, that is, the heating apparatus includes the aforementioned gas system. The heating apparatus herein is a gas heater, or may optionally be a gas cooling stove, a gas oven, a gas air conditioner, or a gas water heater.

[0077] Further, based on the structure and connection relationship of the aforementioned gas system, provided by the inventor is also a temperature regulating control method, including the following steps. [0078] In step S1, a valve switch 13 of the valve switch member 1 is switched to a mild-flame gear so as to allow the burner component 6 to be in the mild-flame state. [0079] In step S2: the valve switch 13 of the valve switch member 1 is switched to a functional gear, in which the burner component 6 is in the high-flame state if the electromagnetic valve 2 receives a control instruction and is in an open state.

[0080] In such an arrangement, the electromagnetic valve 2 is kept in the closed state without receiving a control instruction when the ambient temperature is relatively comfort, i.e., when the second temperature signal, compared by the terminal device, is not higher and/or not lower than the temperature parameter value, at which the burner component 6 is continuously in a mild-flame state when the valve switch 13 of the valve switch member 1 is switched to the functional gear. However, a corresponding control instruction is transmitted to the wireless communication circuit 41 of the temperature control element 4 when the ambient temperature is relative low, so as to control the electromagnetic valve 2 to drive the burner component 6 to switch to the high-flame state.

[0081] Further, the step S1 further includes the following step S11.

[0082] In step S11, the directional valve of the gas system from an NG control gear is switched to an LPG control gear, or the directional valve of the gas system is switched from an LPG control gear to an NG control gear, so that rapid heating and heat-supplying with targeted mild flames for different locations in the environment is achieved.

[0083] Alternatively, the step S2 further includes the following step S21.

[0084] In step S21, the directional valve 3 of the gas system is switched from an NG control gear to an LPG control gear, or the directional valve 3 of the gas system is switched from an LPG control gear to an NG control gear, so that rapid heating and warming with targeted high flames for different locations in the environment is achieved.
