[0042] FIG. 1 partially shows a device 10 in a schematic perspective view. In the embodiment shown in FIG. 1, the device 10 is formed as a household appliance. In particular, the device 10 is formed as a dishwasher, which is also referred to as washer. The device 10 comprises a device body 12, which is a housing in the embodiment shown in FIG. 1. The housing is also referred to as appliance housing. The housing (device body 12) comprises a receiving space 14 also referred to as receiving area, wherein the receiving space 14 and thus the housing comprises an opening 16. The opening 16 opens into the receiving space 14 on the one hand and into an environment of the housing (device body 12) on the other hand. In the embodiment shown in FIG. 1, the receiving space 14 is a treatment chamber for washing dishes.
[0043] Furthermore, the device 10 includes a door 18 also referred to as flap as well as at least one hinge 20. The door 18 is connected to the device body 12 in articulated manner via the hinge 20, that is by means of the hinge 20, such that the door 18 is pivotable between a closed position and at least one open position in relation to the device body 12. In FIG. 1, the door 18 is in an intermediate position, which is between the open position and the closed position. In particular, the open position and the closed position are respective final positions of the door 18, the final positions of which are also referred to as final poses. Therein, the door 18 can be moved into the respective final position, but not be moved beyond the respective final position. In the closed position, the opening 16 and thus the receiving space 14 are, in particular completely, covered and thus closed by the door 18. In the open position, the door 18 uncovers at least a partial area of the opening 16 and thus of the receiving space 14 such that dishes can be moved from the environment into the receiving space 14 or dishes can be moved out of the receiving space 14 to or into the environment in the open position of the door 18. In particular, it is conceivable that the door 18 is connected to the device body 12 in articulated manner by means of at least or exactly one second hinge not apparent in the Figs., wherein the hinges are for example arranged on sides of the device body 12 opposing each other in transverse direction of the device 10. The transverse direction is illustrated by a double arrow 22 in FIG. 1 and runs horizontally in a use position of the device 10 shown in FIG. 1, that is in a horizontal plane. The device 10 takes its use position in its position, that is orientation, provided for its intended use. In particular, the door 18 can be pivoted around a door pivot axis in relation to the device body 12, wherein the door pivot axis runs in transverse direction of the device 10 in the use position of the device 10. The previous and following explanations to the hinge 20 can be readily transferred to the other hinge and vice versa. For example, a person staying in the environment can manually actuate the door 18 and thereby manually pivot it between the closed position and the open position in relation to the device body 12. As is explained in the following, a particularly advantageous actuation of the door 18 can be ensured by means of the hinge 20. Hereto, the hinge 20, as is particularly well apparent from FIG. 2, comprises a base element 24, which is also referred to as support element or support part and is for example formed as a base plate, which is also referred to as support plate. In the embodiment shown in the Figs., the base element 24 is formed separately from the device body 12 and therein at least indirectly, in particular directly, connected to the device body 12. The device body 12 comprises two sidewalls 26 and 28, which are spaced from each other in transverse direction of the device 10 and delimit the receiving space 14 in transverse direction of the device 10. Therein, the base element 24 is for example attached to the sidewall 26, in particular such that relative movements between the sidewall 26 and the base element 24 are prevented. It is apparent that the sidewall 26 is a component of the device body 12.
[0044] In addition, the hinge 20 comprises a hinge arm 30 simply also referred to as arm or pivot arm, which is connected to the base element 24 pivotably around a first pivot axis 32 in relation to the base element 24. In installation position of the hinge 20, the pivot axis 32 extends in transverse direction of the device 10, wherein the hinge 20 takes its installation position in completely produced state of the device 10 and if the device 10 is in its use position provided for its intended use, which is shown in FIG. 1. Therein, the device 10 comprises the hinge 20 in its completely produced state, which is attached to the sidewall 26 in the completely produced state of the device 10. In particular, the door pivot axis is defined by the hinge 20. Therein, it is conceivable that the first pivot axis 32 coincides with the door pivot axis or is the door pivot axis.
[0045] In addition, the hinge 20 comprises a transfer element 34, which is retained on the base element 24 rotatably around a rotational axis 36 in relation to the base element 24. In the embodiment shown in the Figs., the pivot axis 32 and the rotational axis 36 run parallel to each other, wherein the pivot axis 32 and the rotational axis 36 are spaced from each other, in particular in depth direction of the device 10. The depth direction of the device is illustrated by a double arrow 38 and runs perpendicularly to the transverse direction. In the use position of the device 10, the depth direction runs horizontally, hence in the previously mentioned, horizontal plane, such that the transverse direction and the depth direction extend in the common, horizontal plane in the use position of the device 10. Along the depth direction of the device 10, the receiving space 14 is delimited rearwards by a rear wall 40 of the device body 12. In the closed position of the door 18, the receiving space 14 is delimited frontwards by the door 18 in the depth direction of the device 10. In height direction of the device 10, the receiving space 14 is downwards delimited by a bottom of the device body 12 not apparent in the Figs. In height direction of the device upwards, the receiving space 14 is delimited by a ceiling of the device body 12 not apparent in the Figs. The height direction of the device 10 is illustrated by a double arrow 42 and runs perpendicularly to the depth direction and perpendicularly to the transverse direction, wherein the height direction runs in vertical direction, hence runs vertically, in the use position of the device 10.
[0046] Furthermore, the hinge 20 comprises a spring 44 partially apparent in FIG. 2. Presently, the spring 44 is a mechanical spring, hence formed as a solid body. The spring 44 can be formed as a tension spring or else as a compression spring, wherein the spring 44 is for example presently formed as a compression spring. The hinge 20 additionally comprises an actuation element 46, which is coupled to the spring 44. The spring 44 comprises two ends E1 and E2, which are spaced from each other in longitudinal extension direction of the spring 44. In installation position of the hinge 20, the longitudinal extension direction of the spring 44 runs in vertical direction. For example, the end E1 is at least indirectly, in particular directly, supportable or supported on a first stop 48 provided on the base element 24 in longitudinal extension direction of the spring 44, wherein the stop 48 is at least indirectly, in particular directly, provided on the base element 24, in particular such that relative movements between the base element 24 and the stop 48 are omitted. The second end E2 is for example at least indirectly, in particular directly, supportable or supported on the actuation element 46, in particular on a second stop 50 of the actuation element 46, in longitudinal extension direction of the spring 44. For example, the ends E1 and E2 and thus the spring 44 are arranged between the stops 48 and 50 in longitudinal extension direction of the spring 44. As will be explained in the following, the stop 50 is in particular translationally movable, hence displaceable, in longitudinal extension direction of the spring 44 in relation to the stop 48, whereby the spring 44 can be loaded and unloaded.
[0047] For example, if the stop 50 is moved towards the stop 48, thus, the end E2 is moved towards the end E1. Hereby, the spring 44 is compressed and thus loaded. If the stop 50 is, in particular thereupon, moved away from the stop 48, thus, the spring 44 can at least partially relax. In other words, the end E2 can move away from the end E1 such that the spring 44 can increase in its length and thus at least partially relax. By loading the spring 44, the spring 44 provides a spring force, which at least indirectly, in particular directly, acts on the actuation element 46, in particular via the stop 50 of the actuation element 46, in particular in longitudinal extension direction of the spring 44 and thus presently for example in vertical direction.
[0048] It is particularly well apparent in synopsis with FIG. 3b, that the base element 24 comprises a first guide 52. The base element 24 can be single-piece or integrally formed, hence from a single piece. Further, it is conceivable that the base element 24 is multi-part formed and thus comprises multiple components formed separately from each other and thus connected to each other. The actuation element 46 is coupled to the transfer element 34 in articulated manner and displaceable in guided manner along the first guide 52 of the base element 24, hence translationally movable in guided manner. This means that the actuation element 46 can be displaced in guided manner along the guide 52 of the base element 24 and thus in relation to the base element 24. The first guide 52 is or includes a first movement path, which is also referred to as first guide path. Therein, the actuation element 46 for example engages with the first movement path such that the actuation element 46 can be displaced in guided manner along the first movement path and thus in relation to the base element 24. The first movement path is or defines a first movement direction, along which the actuation element 46 can be displaced in guided manner in relation to the base element 24. In the embodiment shown in the Figs., the first guide 52 and thus the first movement path rectilinearly run in the first movement direction along a first straight line, which presently runs in vertical direction, hence runs vertically, in installation position of the hinge 20. Thus, the first guide 52 vertically extends such that the first guide 52 is a vertical guide, in particular a vertical sliding guide. By displacing the actuation element 46 effected along the first guide 52 and thus along the first movement path and along the first movement direction, the displacement of which is effected in vertical direction, in particular related to the installation position of the hinge 20, in that the first guide 52 vertically runs, the spring can be loaded and unloaded.
[0049] In FIG. 2, a first direction is illustrated by an arrow 54, which coincides with the first movement direction or runs parallel to the first movement direction. In addition, a second direction is illustrated by an arrow 56, which is opposite to the first direction and coincides with the first movement direction or extends parallel to the first movement direction.
[0050] In FIGS. 3a and 3b, the actuation element 46 is for example in a first actuation position. In FIG. 2, the actuation element 46 is for example in a second actuation position. The actuation element 46 can be moved from the first actuator position into the second actuation position in that the actuation element 46 is shifted or displaced along the first guide 52 in the first direction in relation to the base element 24. Hereby, the stop 50 is for example moved towards the stop 48, whereby the spring 44 is loaded, presently compressed and loaded. If the actuation element 46 is thereupon for example shifted or displaced along the first guide 52 in the second direction opposite to the first direction in relation to the base element 24, thus, the actuation element 46 is displaced or shifted from the second actuation position into the first actuation position hereby, that is for example shifted back. Hereby, the stop 50 is for example moved away from the stop 48, whereby the spring 44 can at least partially relax. It is apparent that the spring force of the spring 44 is opposed to the displacement of the actuation element 46 from the first actuation position into the second actuation position. For example, the spring force of the spring 44 can effect or at least support the displacement of the actuation element 46 from the second actuation position into the first actuation position.
[0051] In addition, the hinge 20 comprises a lever element 58, which is connected to the transfer element 34 pivotably around a second pivot axis 60 in relation to the transfer element 34. In addition, the lever element 58 is connected to the hinge arm 30 pivotably around a third pivot axis 62 in relation to the hinge arm 30. It is apparent that the pivot axes 60 and 62 run parallel to each other and are spaced from each other, wherein the pivot axes 60 and 62 run in transverse direction of the device 10, in particular in installation position of the hinge 20. Thus, it is provided in the embodiment shown in the Figs., that the pivot axes 32, 60 and 62 and the rotational axis 36 run parallel to each other and are spaced from each other, in particular considered in pairs. In addition, the pivot axes 32, 60 and 62 and the rotational axis 36 run in transverse direction of the device 10 in installation position of the hinge 20. It is apparent that the lever element 58 is connected both to the hinge arm 30 (pivot arm) in articulated manner and to the transfer element 34 in articulated manner. Hereby, by pivoting or swiveling the hinge arm 30 effected around the first pivot axis 32 and in relation to the base element 24, the transfer element 34 is drivable by the hinge arm 30 via the lever element 58 and thereby rotatable around the rotational axis 36 in relation to the base element 24, whereby the actuation element 46 is drivable by the transfer element 34 and thereby displaceable along the first guide 52 in relation to the base element 24 and the spring 44 can be loaded and unloaded. The hinge arm 30 is pivotable between a first pivot position shown in FIGS. 3a and 3b and a second pivot position shown in FIGS. 5a and 5b around the first pivot axis 32 in relation to the base element 24. In particular, the pivot positions of the hinge arm 30 are respective final positions of the hinge arm 30, which can be pivoted into the respective final position, but not pivoted beyond the respective final position. FIGS. 4a, b show an intermediate position of the hinge arm 30 also referred to as intermediate pose, wherein the intermediate position is between the first pivot position and the second pivot position.
[0052] For example, a first pivot direction is illustrated by an arrow 64 in FIG. 3a. In addition, a second pivot direction opposite to the first pivot direction is illustrated by an arrow 66 in FIG. 3a. In FIG. 3a, a first rotational direction of the transfer element 34 is illustrated by an arrow 68, and a second rotational direction of the transfer element 34 opposite to the first rotational direction is illustrated by an arrow 70. In the embodiment shown in the Figs., the first pivot position of the hinge arm 30 corresponds to the closed position of the door 18, and the second pivot position of the hinge arm 30 corresponds to the open position of the door 18. In addition, the intermediate position of the hinge arm 30 corresponds to the intermediate position of the door 18 shown in FIG. 1. Thus, if the door 18 is in the closed position, thus, the hinge arm 30, which is also referred to as pivot arm, is in the first pivot position. If the door 18 is opened, thus, the hinge arm 30 is hereby pivoted in the first pivot direction around the pivot axis 32 in relation to the base element 24, in particular such that the door 18 is pivoted from the closed position into the open position and thus the hinge arm 30 is pivoted from the first pivot position into the second pivot position. For example, if the door 18 is thereupon closed, that is pivoted from the open position into the closed position, thus, the hinge arm 30 is hereby pivoted or swiveled in the second pivot direction around the pivot axis 32 in relation to the base element 24 and therein from the second pivot position into the first pivot position. If the hinge arm 30 is pivoted in the first pivot direction, thus, the transfer element 34 is driven via the lever element 58 such that the transfer element 34 is rotated in the first rotational direction around the rotational axis 36 in relation to the base element 24. Hereby, the actuation element 46 is displaced along the first guide 52 such that the actuation element 46 is displaced in the first direction along the first guide 52 and therein displaced from the first actuation position into the second actuation position. Hereby, the spring 44 is loaded. If the transfer element 34 is rotated in the second rotational direction around the rotational axis 36 in relation to the base element 24, in particular in that the hinge arm 30 is pivoted in the second pivot direction, thus, the actuation element 46 is hereby displaced in the second direction along the first guide 52 in relation to the base element 24 and thereby displaced from the second actuation position into the first actuation position, whereby the spring 44 is unloaded.
[0053] It is particularly well apparent from FIGS. 3a, b that the first guide 52 extends in a plane, which runs perpendicularly to the rotational axis 36.
[0054] It is particularly well apparent from FIGS. 3b, 4b and 5b that the base element 24 comprises a second guide 72, which is for example formed as an elongated hole. The second guide 72 is or includes a second movement path, which is also referred to as second guide path. The second guide 72 defines or forms a second movement direction, along which the transfer element 34 and with it the rotational axis 36 are displaceable in guided manner in relation to the base element 24. This means that the transfer element 34 and with it the rotational axis 36 are displaceable in guided manner along the second guide 72 and thus along the second movement path and in relation to the base element 24. In the embodiment shown in the Figs., the second guide 72 and thus the second movement path and thus the second movement direction extend rectilinearly and thus along a second straight line, wherein the second straight line presently runs parallel to the first straight line. Thus, the second straight line and thus the second guide 72 and the second movement path run vertically in installation position of the hinge 20, that is in vertical direction. Therein, the guides 52 and 72 are spaced from each other and in particular separated from each other. Therein, the guides 52 and 72 extend in the same, previously mentioned plane.
[0055] It is particularly well apparent from FIGS. 3a, 4a and 5a that the hinge 20 comprises a brake surface 74, which, in particular directly, exerts a friction force as a brake force on the transfer element 34. The brake force is opposed to a rotation of the transfer element 34 effected around the rotational axis 36 and for example in the first rotational direction (arrow 68) and in relation to the base element 24. In other words, the transfer element 34 is braked by means of the brake force, that is by means of the brake surface 74, if the transfer element 34 is rotated around the rotational axis 36 in relation to the base element 24 in the first rotational direction and/or in the second rotational direction. Hereby, an excessively fast opening of the door 18 and an excessively hard impact of the door 18 in the open position can for example be avoided. In particular, the brake surface 74 is provided on the base element 24 such that relative movements between the brake surface 74 and the base element 24 are omitted. Therein, the brake surface 74 adjoins to the transfer element 34 along the second guide 72 and therein in particular in the second direction. In installation position of the hinge 20, the second direction (arrow 56) runs downwards in vertical direction and the first direction runs upwards (arrow 54) in vertical direction in installation position of the hinge 20.
[0056] The transfer element 34 comprises a contact surface 76, which is in, in particular direct, contact with the brake surface 74, whereby the brake force acts on the contact surface 76. Therein, the contact surface 76 points away from the rotational axis 36 in a direction running perpendicularly to the rotational axis 36, in particular in the second direction, and is for example formed by an outer circumferential lateral surface of the transfer element 34.
[0057] Preferably, it is provided that the brake surface 74 is formed of a first material and the transfer element 34 is formed of a second material different from the first material, whereby the transfer element 34 can be particularly advantageously braked.
[0058] In the embodiment shown in the Figs., it is provided that the brake surface 74 is formed by a brake element 78 formed separately from the base element 24, which is for example formed as a brake pad or also referred to as brake pad. Therein, the brake element 78 is attached to the base element 24, in particular such that relative movements between the brake element 78 and the base element 24 are omitted.
[0059] From a synopsis of FIG. 1 to FIG. 5b, it is apparent that at least a predominant part of the spring 44 is arranged in a lower area UB of the base element 24 in installation position of the hinge 20 or that at least the predominant part of the spring 44 adjoins to the base element 24 downwards in vertical direction in installation position of the hinge 20. In particular, it is conceivable that the spring 44 is arranged in and/or at a foot of the base element 24 for example formed as a support plate. Thereby, a particularly advantageous, in particular particularly compact, construction of the hinge 20 can be realized such that the hinge 20 can be particularly advantageously arranged in the device body 12.
[0060] For example, the actuation element 46 is coupled to the first guide 52 and thus displaceable in guided manner along the guide 52 such that a coupling element 80 (FIG. 3b) of the actuation element 46 engages with the guide 52, in particular with the first movement path thereof. In the embodiment shown in the Figs., the actuation element 46 is coupled to the transfer element 34 in articulated manner such that the actuation element 46, in particular the coupling element 80, (also) engages with a third guide path 82 of the transfer element 34 also referred to as third movement path. Therein, the coupling element 80 and thus the actuation element 46 are displaceable along the third guide path 82 in relation to the transfer element 34. In other words, if the transfer element 34 is rotated around the rotational axis 36 in relation to the base element 24, in particular then and/or in that the hinge arm 30 is pivoted around the pivot axis 32 in relation to the base element 24, thus, the actuation element 46 is displaced in the guide path 82, and the actuation element 46 is driven by the transfer element 34, in particular by at least one wall of the transfer element 34, in particular directly, delimiting the guide path 82, such that the actuation element 46 is displaced in and along the first guide 52. The guide path 82 is also referred to as cam and is arcuately, that is curvilinearly, formed in the embodiment shown in the Figs. Hereby, a respective rotational movement of the transfer element 34 effected around the rotational axis 36 and in relation to the base element 24 can be converted, that is redirected, to a translational movement effected along the first guide 52 and in relation to the base element 24, hence displacement of the actuation element 46. In particular, by configuring, that is constructively designing the cam, an advantageous transmission between the hinge arm 30 and the spring 44 can be adjusted or configured, whereby an advantageous torque in particular opposed to opening the door 18 and also referred to as hinge torque can for example be adjusted or configured.
[0061] For example, it is apparent from FIGS. 3a, 4a and 5a that the transfer element 34 is for example coupled to the lever element 58 in articulated manner such that the transfer element 34, in particular a coupling element 84 of the transfer element 34, engages with a fourth guide 86 of the lever element 58, wherein the coupling element 84 and thus the transfer element 34 are displaceable in guided manner along the guide 86 in relation to the lever element 58. In particular, the guide 86 can be formed as an elongated hole.
[0062] The previously mentioned spring force of the spring 44 is illustrated by a force arrow F1 in FIG. 6. A second force also referred to as lever force is illustrated by a force arrow F2 in FIG. 6. The second force for example results from the fact that it is pulled on the door 18 and on the hinge arm 30 via the door 18, in particular to open the door 18. Alternatively or additionally, the second force can result from the weight force of the door 18, in particular in the intermediate position and/or in the open position of the door 18. Components of the second force also referred to as force components are illustrated by force arrows F2a and F2b, wherein the force component of the second force illustrated by the force arrow F2a acts in vertical direction and therein downwards, hence is a vertical force component. The force component of the second force illustrated by the force arrow F2b acts in horizontal direction and is thus a horizontal force component of the second force. By a force arrow F3, a third force also referred to as sum force is illustrated, which presently acts in vertical direction downwards on the transfer element 34. The sum force results from the spring force (force arrow F1) and from the vertical force component (force arrow F2a), wherein the sum force is in particular the sum of the spring force (force arrow F1) and the vertical force component (force arrow F2a). The spring force and the vertical force component of the second force act in vertical direction downwards. By means of the third force (force arrow F3) acting downwards in vertical direction, the transfer element 34, in particular the contact surface 76 thereof, is pressed, that is squeezed, against the brake surface 74, whereby the brake force acts on the transfer element 34. The brake force is illustrated by a force arrow Fr in FIG. 6 and results from the third force multiplied by the friction value of the brake surface 74. Thereby, the transfer element 34 and thus the door 18 can be advantageously braked.
