Description

Technical Field

[0001] The present invention relates to the field of household appliances, and particularly to a control method for a door body capable of automatically controlling the movement of the door body and a refrigeration device. Background Art

[0002] With the progress of society and the improvement of people's living standards, the placement position and placement method of various household appliances (such as refrigerators in refrigeration devices) in the family are increasingly valued by ordinary users. For the current home decoration styles, some families pursue integrated styles, and it is necessary to embed household appliances in external environmental components (such as cabinets, walls) to form so-called built-in household appliances.

[0003] For built-in household appliances, such as built-in refrigerators, generally include a box body, a door body, and a hinge device for rotatably connecting the door body to the box body. Generally, in order to avoid interference between the door body and the external environmental components when the door body rotates and opens, the door body is set to translate along a preset trajectory while rotating and opening. At this time, when the user manually opens / closes the door body, it is necessary to apply a force to rotate and open the door body and a force to translate along the preset trajectory direction to the door body at the same time, which is not conducive to the smoothness of opening and closing the door body and is not convenient for the user to operate. In addition, for built-in household appliances, if the user opens the door with great force and causes the opening angle to be too large, it is easy to collide with the external environmental components. Summary of the Invention

[0004] The purpose of the present invention is to provide a control method for a door body capable of automatically controlling the movement of the door body and a refrigeration device.

[0005] To achieve the above invention purpose, the present invention adopts the following technical solutions: A control method for a door body, the door body is used to open or close an opening of a box body; the control method for the door body includes the following steps: starting a rotation driving mechanism in the hinge device to drive the door body to rotate to open the opening or close the opening.

[0006] As a further improved technical solution of the present invention, while starting the rotation driving mechanism in the hinge device to drive the door body to rotate to open the opening or close the opening, the control method for the door body further includes the following steps: starting a translation driving mechanism in the hinge device to drive the door body to translate along a preset direction.

[0007] As a further improved technical solution of the present invention, the box body has a pivot side provided with the hinge device and an opening side opposite to the pivot side; while starting the rotation driving mechanism in the hinge device to drive the door body to rotate to open the opening, starting the translation driving mechanism in the hinge device to drive the door body to translate towards the opening side; while starting the rotation driving mechanism in the hinge device to drive the door body to rotate to close the opening, starting the translation driving mechanism in the hinge device to drive the door body to translate towards the pivot side.

[0008] As a further improved technical solution of the present invention, the door body includes a front wall of the door facing away from the box body when closed, and a side wall of the door located on the pivoting side. The front wall of the door and the side wall of the door intersect to form an outer edge of the door. During the process of the rotary drive mechanism driving the door body to rotate and open to 90°, or during the process of the rotary drive mechanism driving the door body to rotate and close from 90°, the outer edge of the door is located on the side of the plane where the pivoting side faces the opening side.

[0009] As a further improved technical solution of the present invention, the speed at which the translation drive mechanism drives the door body to translate Wherein, d1 is the distance between the side wall of the door and the rotation axis of the door body, d2 is the distance between the front wall of the door and the rotation axis of the door body, θ is the opening angle of the door body, the door body has an installation end face for installing the hinge device, the outer edge of the door intersects the installation end face at point N, θ1 is the included angle between the line connecting the rotation axis of the door body and point N and the vertical line passing through the rotation axis of the door body and perpendicular to the front wall of the door, and a is the preset safe distance between the outer edge of the door and the plane where the pivoting side is located.

[0010] As a further improved technical solution of the present invention, a is 3 mm.

[0011] As a further improved technical solution of the present invention, the door body includes an opposite first door body, a second door body, and a flipping beam rotatably connected to one end of the first door body close to the second door body. The flipping beam has a horizontal state parallel to the first door body and a vertical state perpendicular to the first door body;

[0012] When starting the rotary drive mechanism in the hinge device to drive the first door body to rotate and close the opening, when a signal that the first door body is blocked from closing is obtained, it is determined that the flipping beam is in the horizontal state.

[0013] As a further improved technical solution of the present invention, when starting the rotary drive mechanism in the hinge device to drive the first door body to rotate and close the opening, and after determining that the flipping beam is in the horizontal state, the control method of the door body further includes the following steps:

Then, the rotation driving mechanism corresponding to the first door body is activated to drive the first door body to rotate and close, and the rotation driving mechanism corresponding to the second door body is activated to drive the second door body to rotate and close until the turning beam is located on the side of the second door body facing the box body and the turning beam in the horizontal state is on the moving path of the second door body rotating and closing. Then, the rotation driving mechanism corresponding to the first door body is activated to drive the first door body to rotate and open, and at the same time, the rotation driving mechanism corresponding to the second door body is activated to drive the second door body to rotate and close. The end of the second door body close to the first door body pushes the turning beam to switch from the horizontal state to the vertical state; wherein, the second angle range is greater than the first angle range.

[0017] As a further improved technical solution of the present invention, the first preset angle is 15°.

[0018] To achieve the above-mentioned invention purpose, the present invention also provides a refrigeration device, which includes a box body with an opening, a door body for opening or closing the opening, and a hinge device for movably connecting the door body to the box body; the door body is controlled by the above-mentioned control method of the door body.

[0033] The present invention will be described in detail below in conjunction with the various implementation manners shown in the drawings. Please refer to Figures 1 to 13As shown, this is a preferred embodiment of the present invention. It should be noted, however, that these embodiments are not limitations on the present invention, and any equivalent transformation or substitution in function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present invention.

[0034] Spatial relative position terms used herein, such as "front", "rear", "upper", "lower", etc., are based on the side where the door body is located when the household appliance is in normal use. The other "rear", "upper", "lower" are all referenced with the front as the reference. These spatial relative position terms are used for the purpose of facilitating the description of the relationship of one unit or feature to another unit or feature as shown in the accompanying drawings. The spatial relative position terms may be intended to include different orientations of the device in addition to the orientation shown in the figures during use or operation. For example, if the device in the figure is flipped, the unit described as being "below" or "beneath" other units or features will be located "above" other units or features. Therefore, the exemplary term "upper" can encompass both the upper and lower orientations. The device can be oriented in other ways (rotated 90° or other orientations), and the spatially related descriptive terms used herein can be interpreted accordingly.

[0035] Moreover, it should be understood that although terms such as first, second, etc. may be used herein to describe various elements or structures, the objects described should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0036] In the illustration of the present invention, for the convenience of illustration, certain dimensions of the structure or part are exaggerated relative to other structures or parts. Therefore, it is only used to illustrate the basic structure of the subject matter of the present invention.

[0037] Please refer Figures 1 - 11 As shown, the present invention provides a household appliance 100, which includes a box body 1, a door body 2, a hinge device 3 connected between the door body 2 and the box body 1, and a control unit for controlling the operation of the household appliance 100. The box body 1 has an opening, and the door body 2 is used to open or close the opening.

[0038] In this embodiment, the household appliance 100 is a refrigeration device, especially an embedded refrigerator. Of course, it is not limited thereto. In other embodiments, the household appliance 100 may also be other household appliances such as a microwave oven or a non-embedded household appliance.

[0039] The specific model of the control unit is not limited in the present invention, and any control unit that can control the operation of the household appliance 100 according to a predetermined program shall fall within the protection scope of the present invention.

[0040] Combined with Figures 2 to 4As shown, the hinge device 3 includes a hinge plate 31 connected to the cabinet 1 and a rotary drive mechanism 36 provided on the hinge plate 31. The door body 2 is rotatably connected to the hinge plate 31 through the rotary drive mechanism 36. The rotary drive mechanism 36 is communicatively connected to the control unit to drive the door body 2 to rotate relative to the hinge plate 31, that is, relative to the cabinet 1. Thus, through the hinge device 3 in the present invention, automatic opening / closing of the door can be achieved, without the need for the user to manually operate the door, which is convenient for the user to use the household appliance. At the same time, the opening angle of the door body 2 can be accurately controlled through the rotary drive mechanism 36. Especially for built-in household appliances in built-in application scenarios, it can prevent the door body 2 from colliding with external environmental components due to an overly large opening angle.

[0041] Specifically, the hinge plate 31 has a perforation 316, and the hinge device 3 includes a rotating shaft 37 mounted on the door body 2 and rotatably connected to the perforation 316. The rotary drive mechanism 36 includes a rotary drive motor 361 mounted on the hinge plate 31, a rotary drive gear 362 mounted on the output end of the rotary drive motor 361, a shaft drive gear 363 connected to the rotating shaft 37, and at least one transmission gear 364 for transmitting the power of the rotary drive gear 362 to the shaft drive gear 363. The rotary drive gear 362 meshes with the starting gear of the at least one transmission gear 364, and the shaft drive gear 363 meshes with the end gear of the at least one transmission gear 364. When the rotary drive motor 361 starts to drive the rotary drive gear 362 to rotate, the driving force is transmitted to the shaft drive gear 363 through the transmission gear 364, driving the shaft drive gear 363 to rotate. The shaft drive gear 363 drives the rotating shaft 37 to rotate, and the rotating shaft 37 drives the door body 2 to rotate synchronously to achieve the rotary opening or rotary closing of the door body 2.

[0042] It can be understood that when there is only one transmission gear 364, both the rotary drive gear 362 and the shaft drive gear 363 mesh with this transmission gear 364.

[0043] In a specific embodiment, the rotary drive mechanism 36 is mounted on the side of the hinge plate 31 away from the door body 2, that is, the door body 2 and the shaft drive gear 363 are respectively located on opposite sides of the hinge plate 31. Of course, this is not the limit.

[0044] Further, a shaft hole 21 for installing the rotating shaft 37 is recessed in the door body 2, and the household appliance 100 further includes a limiting structure 4 disposed between the rotating shaft 37 and the shaft hole 21 to limit the rotation of the rotating shaft 37 relative to the shaft hole 21. Thus, setting the rotating shaft 37 to be detachably connected to the door body 2 is beneficial to the assembly between the hinge device 3 and the door body 2.

[0045] In a specific embodiment, the limiting structure 4 includes a plurality of limiting protrusions 41 protruding from the inner peripheral wall of the shaft hole 21 along the circumferential direction of the shaft hole 21, and a plurality of limiting grooves 42 recessed in the outer peripheral surface of the rotating shaft 37. The plurality of limiting grooves 42 correspond to the plurality of limiting protrusions 41 one by one. By the cooperation of the limiting groove 42 and the limiting protrusion 41, the rotation of the rotating shaft 37 relative to the shaft hole 21 is restricted, so that the door body 2 and the rotating shaft 37 can rotate synchronously.

[0046] Further, the shaft driving gear 363 and the rotating shaft 37 are integrally provided, which improves the stability of the shaft driving gear 363 driving the rotating shaft 37 to rotate, and simplifies the structure of the hinge device 3 and its assembly.

[0047] Further, the hinge device 3 further includes a support shaft sleeve 38 sleeved on the rotating shaft 37. The support shaft sleeve 38 is located between the hinge plate 31 and the door body 2, which can reduce the shaking during the rotation of the door body 2 and improve the stability of the rotation of the door body 2.

[0048] In this embodiment, in combination with Figure 1 as shown, the door body 2 is a vertical door body 2 extending in the vertical direction, and the hinge device 3 includes an upper hinge device 3a disposed on the upper side of the door body 2 and a lower hinge device 3b disposed on the lower side of the door body 2. The rotation driving mechanism 36 is provided in the upper hinge device 3a, and the rotation driving mechanism 36 is not provided in the lower hinge device 3b. For the lower hinge device 3b, the door body 2 is rotatably connected to a rotating shaft fixed to the hinge plate 31. Of course, this is not a limitation.

[0049] Further, the hinge plate 31 is slidably connected to the cabinet 1 in a preset direction. The hinge device 3 further includes a translation driving mechanism 32 disposed between the hinge plate 31 and the cabinet 1. The translation driving mechanism 32 is communicatively connected to the control unit to drive the hinge plate 31 to translate relative to the cabinet 1 in the preset direction. It can be known that when the hinge plate 31 translates relative to the cabinet 1 in the preset direction, the door body 2 is synchronously driven to translate in the preset direction. When the rotation driving mechanism 36 automatically drives the door body 2 to rotate to open / close the door body 2, the door body 2 is synchronously and automatically driven to translate in the preset direction by the translation driving mechanism 32. For the household appliance 100 in the present invention, when the door body 2 needs to translate and rotate, the opening / closing of the door body 2 can be fully automatically realized, that is, the door body 2 is automatically driven to rotate and simultaneously automatically driven to translate, without the need for the user to apply an additional driving force, which facilitates the user to operate the opening and closing of the door body 2 and can also improve the smoothness of the opening and closing of the door body 2.

[0050] Specifically, the cabinet 1 has a pivot side where the hinge device 3 is provided and an opening side opposite to the pivot side. The arrangement direction of the pivot side and the opening side is defined as the horizontal direction. The direction from the pivot side to the opening side is the first direction F1, and the direction from the opening side to the pivot side is the second direction F2. It can be known that the definitions of the first direction F1 and the second direction F2 correspond to the door body 2 one by one. For a side-by-side refrigerator, the first direction F1 and the second direction F2 of the two opposite door bodies 2 are opposite.

[0051] In this embodiment, the preset direction is the horizontal direction, that is, the hinge plate 31 is slidably connected to the cabinet 1 in the horizontal direction. In a specific embodiment, in combination with Figures 5 to 6As shown, during the process of the door body 2 rotating and opening, the translation driving mechanism 32 drives the hinge plate 31 to move along the first direction F1, so that the household appliance 100 is applicable to an embedded application scenario, such as an embedded refrigeration device, especially an embedded refrigerator. While the door body 2 rotates and opens, the translation driving mechanism 32 drives the hinge plate 31 to drive the door body 2 to move along the first direction F1 away from the external environmental component located on the pivoting side, thereby being able to avoid interference / collision between the door body 2 and the external environmental component, and enabling the door body 2 to open smoothly. Correspondingly, during the process of the door body 2 rotating and closing, the translation driving mechanism 32 drives the hinge plate 31 to drive the door body 2 to move in a reset manner along the second direction F2, so that the door body 2 can be reset to the initial closed state. For an embedded refrigeration device, it can enable the door body 2 to seal the opening and avoid leakage of cold. Of course, it is not limited thereto. In other embodiments, when the preset direction is the horizontal direction, according to specific requirements, it can also be set that when the door body 2 rotates and opens, the translation driving mechanism 32 drives the hinge plate 31 to drive the door body 2 to move along the second direction F2 to increase the opening degree of the door body 2 and avoid the door body 2 affecting the pulling out of the drawer / shelf in the cabinet 1; or during the stage when the door body 2 rotates and opens, the moving direction of the translation driving mechanism 32 driving the hinge plate 31 to drive the door body 2 is not limited to a single first direction F1 or second direction F2, such as it can first move along the first direction F1 and then move along the second direction F2, etc.; or the preset direction is not limited to the horizontal direction and can be set according to specific requirements, such as the direction perpendicular to the plane where the opening is located, that is, the front-back direction, etc.

[0052] Specifically, in combination with Figures 2 to 3 and Figures 7 to 8 As shown, the hinge plate 31 has a first side facing the cabinet 1; the hinge device 3 further includes a guiding groove 33 recessed in the first side and extending along the preset direction, and a guiding block 34 installed on the cabinet 1 and cooperating with the guiding groove 33. Through the cooperation of the guiding block 34 and the guiding groove 33, the hinge plate 31 is slidably connected to the cabinet 1 along the preset direction, with a simple structure and convenient assembly.

[0053] In combination with Figure 1 As shown, in the embodiment where the door body 2 is a vertical door body and the hinge device 3 includes an upper hinge device 3a and a lower hinge device 3b, in combination with Figures 2 to 3 As shown, the hinge plate 31a in the upper hinge device 3a is in a straight plate shape, and the first side is the lower surface of the hinge plate 31a. In combination with Figures 7 to 8As shown, the hinge plate 31b in the lower hinge device 3b is in a T shape. The hinge plate 31b includes a fixing plate 311 for fixing to the box body 1, and a connecting plate 312 connected to and perpendicular to the fixing plate 311. The door body 2 is rotatably connected to the connecting plate 312. The first side is the side where the fixing plate 311 faces the box body 1, that is, the rear surface of the fixing plate 311.

[0054] Further, in the direction away from the box body 1, the cross-section of the guiding block 34 is a trapezoid with a gradually increasing cross-section, and the cross-section of the guiding groove 33 is adapted to the cross-section of the guiding block 34. After the guiding groove 33 and the guiding block 34 are matched, the hinge plate 31 can be limited and fixed, avoiding the guiding groove 33 and the guiding block 34 from separating in the direction perpendicular to the first side. The structure is simple, and the sliding connection structure between the hinge plate 31 and the box body 1 is simplified.

[0055] Specifically, the cross-section of the guiding block 34 is a non-right-angled trapezoid, preferably an isosceles trapezoid. Of course, it is not limited thereto.

[0056] Further, the translation driving mechanism 32 includes a translation driving motor 321 provided on one of the box body 1 and the hinge plate 31, a translation driving gear 322 installed at the output end of the translation driving motor 321, and a rack 323 provided on the other and extending along the preset direction. The translation driving gear 322 meshes with the rack 323. By driving the translation driving gear 322 to rotate through the translation driving motor 321, the translation driving gear 322 meshes with the rack 323 and moves relatively, thereby driving the hinge plate 31 to translate along the preset direction.

[0057] Further, the translation driving mechanism 32 further includes a gear set 324 provided between the translation driving gear 322 and the rack 323. The translation driving gear 322 and the rack 323 are indirectly meshed through the gear set 324. The gear set 324 includes a large gear 3241 and a small gear 3242 coaxially arranged. The translation driving gear 322 meshes with the small gear 3242, and the rack 323 meshes with the large gear 3241. The driving force of the translation driving motor 321 can be amplified through the gear set 324. Thus, a smaller translation driving motor 321 can also provide the driving force for driving the door body 2 to translate, and the overall size of the hinge device 3 can be reduced.

[0058] When the hinge device 3 includes an upper hinge device 3a provided on the upper side of the door body 2 and a lower hinge device 3b provided on the lower side of the door body 2, in a specific embodiment, in combination with Figures 2 to 3As shown, the translation drive mechanism 32a in the upper hinge device 3a includes a translation drive motor 321 provided on one of the box body 1 and the hinge plate 31, a translation drive gear 322 mounted on the output end of the translation drive motor 321, a rack 323 provided on the other and extending along the preset direction, and a gear set 324 provided between the translation drive gear 322 and the rack 323. In combination Figures 7 to 8 As shown, the translation drive mechanism 32b in the lower hinge device 3b includes a translation drive motor 321 provided on one of the box body 1 and the fixing plate 311, a translation drive gear 322 mounted on the output end of the translation drive motor 321, and a rack 323 provided on the other and extending along the preset direction. That is, the translation drive mechanism 32a in the upper hinge device 3a includes the gear set 324 to provide a greater driving force for the translation of the door body 2. The translation drive mechanism 32b in the lower hinge device 3b does not include the gear set 324. At this time, during the process of the door body 2 rotating and opening, the driving force for the translation of the door body 2 is mainly provided by the translation drive mechanism 32a in the upper hinge device 3a. The translation drive mechanism 32b in the lower hinge device 3b only needs to be set to be able to move synchronously with the translation drive mechanism 32a in the upper hinge device 3a. At the same time, the translation drive mechanism 32b in the lower hinge device 3b does not include the gear set 324, which can reduce the installation space of the lower hinge device 3b and can also take into account the problem of limited installation space of the lower hinge device 3b. Of course, this is not a limitation. In other embodiments, the translation drive mechanisms 32 in the upper hinge device 3a and the lower hinge device 3b can also be set to be the same, that is, both have the gear set 324 or both do not have the gear set 324; or the translation drive mechanism 32a in the upper hinge device 3a does not have the gear set 324, and the translation drive mechanism 32b in the lower hinge device 3b has the gear set 324.

[0059] In a specific embodiment regarding the installation of the translation drive mechanism 32, the translation drive mechanism 32 is provided between the first side and the box body 1. That is, the translation drive mechanism 32 will not be exposed outward from the hinge plate 31. Specifically, the box body 1 has an installation port in the installation part for installing the translation drive mechanism 32, and a buried box 11 for installing the translation drive mechanism 32 is provided in the installation port.

[0060] In this embodiment, the translation driving motor 321 is installed in the embedded box 11, and the rack 323 is integrally provided with the hinge plate 31. It can be understood that a strip-shaped tooth-like structure meshing with the translation driving gear 322 is formed on the first side of the hinge plate 31. This can simplify the structure and installation of the translation driving mechanism 32.

[0061] In another specific embodiment regarding the installation of the translation driving mechanism 32, the hinge plate 31 has a second side facing away from the box body 1, a first installation groove 313 recessed from the first side towards the second side, a second installation groove 314 recessed from the second side towards the first side, and a communication portion 315 connecting the first installation groove 313 and the second installation groove 314; the translation driving motor 321 or the rack 323 installed in the hinge plate 31 is installed in the second installation groove 314, the translation driving motor 321 or the rack 323 installed in the box body 1 is received in the first installation groove 313, and the translation driving gear 322 meshes with the rack 323 at the communication portion 315. At this time, the translation driving motor 321 and the rack 323 are installed on opposite sides of the hinge plate 31, which can further reduce the thickness of the hinge plate 31 and is beneficial to the miniaturization of the hinge device 3.

[0062] In this embodiment, the rack 323 is installed on the box body 1, and the translation driving motor 321 is installed on the hinge plate 31, that is, the rack 323 is received in the first installation groove 313, and the translation driving motor 321 is installed in the second installation groove 314. In the embodiment where the translation driving mechanism 32 includes the gear set 324, the gear set 324 is rotatably connected in the second installation groove 314, and the large gear 3241 in the gear set 324 meshes with the rack 323 at the communication portion 315.

[0063] Furthermore, in the direction away from the box body 1, the cross-section of the first installation groove 313 is a trapezoid with a gradually increasing cross-section, and the cross-section of the rack 323 is adapted to the cross-section of the first installation groove 313. The cooperation between the first installation groove 313 and the rack 323 can further limit the hinge plate 31 and prevent the hinge plate 31 from disengaging from the rack 323 in the direction perpendicular to the plane of the first side. Of course, this is not limited thereto.

[0064] Specifically, the cross-section of the rack 323 is a right trapezoid, and the angle corresponding to the side of the rack 323 with the strip-shaped tooth-like structure is a right angle, and the angle corresponding to the other side opposite to the strip-shaped tooth-like structure is a non-right angle.

[0065] Further, the hinge device 3 further includes a shielding cover 35 covering the side of the hinge plate 31 away from the cabinet 1. The shielding cover 35 shields the translation driving structure, thereby improving the overall appearance effect of the household appliance 100.

[0066] Combined with Figures 7 to 9 As shown, in this embodiment, for the lower hinge device 3b, the translation driving mechanism 32b is disposed between the first side and the cabinet 1, that is, the translation driving mechanism 32b is disposed between the fixing plate 311 and the cabinet 1. Specifically, the rack 323 is integrally formed with the fixing plate 311, and the translation driving motor 321 is installed in the embedded box 11. At this time, the shielding cover 35 does not need to be provided, simplifying the structure of the lower hinge device 3b. Combined with Figures 2 to 3 As shown, for the upper hinge device 3a, the translation driving motor 321 and the rack 323 in the translation driving mechanism 32a are located on opposite sides of the hinge plate 31. Specifically, the translation driving motor 321 and the gear set 324 are located in the second installation groove 314, and the rack 323 is received in the first installation groove 313. It can be known that the shielding cover 35 will be provided for the upper hinge device 3a itself, thereby avoiding the external leakage of the translation driving mechanism 32. Of course, this is not a limitation.

[0067] Further, combined with Figure 10 As shown, the household appliance 100 further includes a door closing self-locking member 5 disposed between the door body 2 and the hinge device 3. The door closing self-locking member 5 is used to keep the door body 2 in a closed state, which can prevent the door body 2 from opening again due to inertia and improve the stability and sealing performance of the door body 2 in the closed state.

[0068] In a specific embodiment, the door closing self-locking member 5 includes a latch 51 disposed on the hinge plate 31 and a hook 52 disposed on the door body 2. After the hook 52 is engaged with the latch 51, the door body 2 is in a closed state. After the hook 52 disengages from the latch 51, the door body 2 is in an open state.

[0069] In this embodiment, the hinge device 3 includes an upper hinge device 3a disposed on the upper side of the door body 2 and a lower hinge device 3b disposed on the lower side of the door body 2. The door closing self-locking member 5 is disposed between the lower hinge device 3b and the door body 2, simplifying the structure of the upper hinge device 3a. Of course, this is not a limitation.

[0070] Further, the present invention also provides a control method for the door body 2 in the above-mentioned household appliance 100. The structure of the household appliance 100 is as shown above, and will not be elaborated here.

[0071] The control method of the door body 2 includes the following steps:

[0072] Start the rotary drive mechanism 36 in the hinge device 3 to drive the door body 2 to rotate to open or close the opening of the cabinet 1.

[0073] In the control method of the door body 2 in the present invention, automatic opening / closing of the door can be achieved, without the need for the user to manually operate the door, which is convenient for the user to use the household appliance 100; at the same time, the opening angle of the door body 2 can be accurately controlled. Especially for built-in household appliances in built-in application scenarios, it can prevent the door body 2 from colliding with external environmental components due to an overly large opening angle.

[0074] Further, as shown in Figures 12 to 13 In a specific embodiment, the household appliance 100 is a side-by-side refrigerator. That is, the door body 2 includes opposite first door body 25, second door body 26, and a flip beam 27 rotatably connected to one end of the first door body 25 close to the second door body 26. The flip beam 27 has a horizontal state parallel to the first door body 25 and a vertical state perpendicular to the first door body 25. One end of the flip beam 27 has a guide block, and a guide groove is provided in the cabinet 1 and is matched with the guide block. When the first door body 25 is in the closed state, the guide block is located in the guide groove, and the flip beam 27 is in the horizontal state to seal the gap between the first door body 25 and the second door body 26 to prevent cold leakage; when the first door body 25 rotates and opens from the closed state, the guide block moves outward along the guide groove, driving the flip beam 27 to switch from the horizontal state to the vertical state. When the first door body 25 rotates and closes from the open state until the guide block on the flip beam 27 enters the guide groove entrance and continues to close, the guide block moves inward along the guide groove, driving the flip beam 27 to switch from the vertical state to the horizontal state. At this time, during the process of starting the rotary drive mechanism 36 in the hinge device 3 to drive the first door body 25 to rotate to close the opening, the control method of the door body 2 further includes the following steps:

[0075] When a signal indicating that the closing of the first door body 25 is blocked is obtained, it is determined that the flip beam 27 is in the horizontal state.

[0076] It can be known that before the first door body 25 rotates and closes from the open state until the guide block on the flip beam 27 does not enter the guide groove, if the flip beam 27 is in the horizontal state, it will cause the closing of the first door body 25 to be blocked, that is, the first door body 25 cannot continue to rotate and close. Therefore, when the control unit obtains a signal indicating that the closing of the first door body 25 is blocked, it is determined that the flip beam 27 is in the horizontal state.

[0077] Specifically, when the control unit receives a signal fed back by the rotary drive motor 361 corresponding to the first door body 25 indicating that the rotation is blocked, it is determined that the closing of the first door body 25 is blocked.

[0078] Further, when starting the rotary drive mechanism 36 in the hinge device 3 to drive the first door body 25 to rotate and close the opening, and after determining that the turning beam 37 is in a horizontal state, the control method of the door body 2 further includes the following steps:

[0079] Obtain the opening angle of the first door body 25 when the closing of the first door body 25 is blocked;

[0080] As Figure 12 shown, when the opening angle of the first door body 25 is within the first angle range, it is determined that the second door body 26 is in an open state. Start the rotary drive mechanism 36 corresponding to the second door body 26 to drive the second door body 26 to close. After the end of the second door body 26 facing the first door body 25 reaches a first preset angle on the movement path of the turning beam 27 in a horizontal state, start the rotary drive mechanism 36 corresponding to the first door body 25 to drive the first door body 25 to rotate and open, and at the same time, start the rotary drive mechanism 36 corresponding to the second door body 26 to drive the second door body 26 to continue closing from the first preset angle. The end of the second door body 26 close to the first door body 25 pushes the turning beam 27 to switch from a horizontal state to a vertical state;

[0081] As Figure 13 shown, when the opening angle of the first door body 25 is within the second angle range, it is determined that the second door body 26 is in a closed state. Start the rotary drive mechanism 36 corresponding to the first door body 25 to drive the first door body 25 to rotate and open, and start the rotary drive mechanism 36 corresponding to the second door body 26 to drive the second door body 26 to rotate and open until the end of the second door body 26 facing the first door body 25 is away from the movement path of the turning beam 27. Then, start the rotary drive mechanism 36 corresponding to the first door body 25 to drive the first door body 25 to rotate and close, and start the rotary drive mechanism 36 corresponding to the second door body 26 to drive the second door body 26 to rotate and close until the turning beam 27 is located on the side of the second door body 26 facing the box body 1 and the turning beam 27 in a horizontal state is on the movement path of the rotation and closing of the second door body 26. Then, start the rotary drive mechanism 36 corresponding to the first door body 25 to drive the first door body 25 to rotate and open, and at the same time, start the rotary drive mechanism 36 corresponding to the second door body 26 to drive the second door body 26 to rotate and close. The end of the second door body 26 close to the first door body 25 pushes the turning beam 27 to switch from a horizontal state to a vertical state; wherein, the second angle range is greater than the first angle range.

[0082] In the control method of the door body 2 in the present invention, when the closing of the first door body 25 is blocked because the turning beam 27 is in a horizontal state, by driving the first door body 25 and the second door body 26 to move relative to each other, the turning beam 27 is pushed by the second door body 26 to switch to a vertical state. Thus, the state where the closing of the first door body 25 is blocked can be released, enabling the first door body 25 to close smoothly, and the state where the closing of the first door body 25 is blocked can be automatically released, improving the automatic control of the household appliance 100.

[0083] As Figure 12 shown, when the closing of the first door body 25 is blocked and the second door body 26 is in an open state, the turning beam 27 is located between the second door body 26 and the opening side of the cabinet 1. At this time, as long as the second door body 26 is first rotated and closed to a first preset angle, and then the first door body 25 and the second door body 26 are driven to rotate relative to each other, the turning beam 27 can be pushed to switch to a vertical state. As Figure 13 shown, when the closing of the first door body 25 is blocked and the second door body 26 is in a closed state, at this time, the turning beam 27 is located on the side of the second door body 26 away from the cabinet 1. Even if the first door body 25 and the second door body 26 are driven to rotate relative to each other, it is impossible to push the turning beam 27 to switch to a vertical state through the second door body 26. Therefore, it is necessary to first rotate and open the first door body 25 and the second door body 26, then rotate and close the first door body 25 so that the turning beam 27 is located between the second door body 26 and the cabinet 1, and then rotate and close the second door body 26 to the first preset angle so that the turning beam 27 in a horizontal state is located on the first-stage path of the rotation and closing of the second door body 26. Finally, driving the first door body 25 and the second door body 26 to rotate relative to each other can push the turning beam 27 to switch to a vertical state.

[0084] In a specific embodiment, the first preset angle is 15°. Of course, this is not a limitation.

[0085] Specifically, as shown in Figures 12 to 13 , when the second door body 26 is in an open state and the closing of the first door body 25 is blocked, the turning beam 27 contacts the opening side of the cabinet 1. When the second door body 26 is in a closed state and the closing of the first door body 25 is blocked, the turning beam 27 contacts the second door body 26. Thus, the second angle range is greater than the first angle range.

[0086] In a specific embodiment, the first angle range is not greater than 11°, and the second angle range is (11°, 15°). Of course, this is not a limitation.

[0087] Further, when the hinge device 3 further includes the translation driving mechanism 32, while starting the rotation driving mechanism 36 in the hinge device 3 to drive the door body 2 to rotate to open or close the opening, the control method of the door body 2 further includes the following steps: starting the translation driving mechanism 32 in the hinge device 3 to drive the door body 2 to translate in a preset direction.

[0088] In the control method of the door body 2 in the present invention, full-automatic door opening can be realized, liberating the user's hands and improving the automation of the household appliance 100.

[0089] In a specific embodiment, while starting the rotation driving mechanism 36 in the hinge device 3 to drive the door body 2 to rotate to open the opening, start the translation driving mechanism 32 in the hinge device 3 to drive the door body 2 to translate toward the opening side, that is, drive the door body 2 to move along the first direction F1, so that the household appliance 100 is suitable for an embedded application scenario, such as an embedded refrigeration device, especially an embedded refrigerator. While the door body 2 rotates and opens, the translation driving mechanism 32 drives the hinge plate 31 to drive the door body 2 to move away from the external environmental component located on the pivot side along the first direction F1. Thus, interference / collision between the door body 2 and the external environmental component can be avoided, enabling the door body 2 to open smoothly. While starting the rotation driving mechanism 36 in the hinge device 3 to drive the door body 2 to rotate to close the opening, start the translation driving mechanism 32 in the hinge device 3 to drive the door body 2 to translate toward the pivot side, that is, drive the door body 2 to move back along the second direction F2, so that the door body 2 can be reset to the initial closed state. For an embedded refrigeration device, the door body 2 can seal the opening to avoid leakage of cold. Of course, this is not limiting.

[0090] Specifically, in combination with Figure 11As shown, the door body 2 includes a front door wall 22 facing away from the box body 1 when closed, and a door side wall 23 located on the pivot side. The front door wall 22 and the door side wall 23 intersect to form an outer edge of the door. Further, during the process of the rotary drive mechanism 36 driving the door body 2 to rotate and open to 90°, or during the process of the rotary drive mechanism 36 driving the door body 2 to rotate and close from 90°, the outer edge of the door is located on the side of the plane where the pivot side is located facing the opening side. That is, during the process of the rotary drive mechanism 36 driving the door body 2 to rotate and open to 90°, or during the process of the rotary drive mechanism 36 driving the door body 2 to rotate and close from 90°, through the cooperation of the translation drive mechanism 32, the outer edge of the door will not exceed the plane where the pivot side of the box body 1 is located, so that the household appliance 100 is applicable to a zero-clearance embedded application scenario, such as a zero-clearance embedded refrigeration device, especially a zero-clearance embedded refrigerator, which can avoid interference / collision between the door body 2 and the external environmental components, and enable the door body 2 to open / close smoothly.

[0091] Specifically, as shown in the figure, while the rotary drive mechanism 36 drives the door body 2 to rotate and open / close, the translation drive mechanism 32 drives the door body 2 to translate at a speed wherein, d1 is the distance from the door side wall to the rotation axis of the door body 2, d2 is the distance from the front door wall to the rotation axis of the door body 2, and θ is the opening angle of the door body 2. The door body 2 has an installation end face 24 for installing the hinge device 3. The outer edge of the door intersects the installation end face 24 at point N. θ1 is the angle between the line connecting the rotation axis of the door body 2 and point N and the vertical line passing through the rotation axis 37 of the door body 2 and perpendicular to the front door wall. a is a preset safe distance from the outer edge of the door to the plane where the pivot side is located. It can ensure that the outer edge of the door will not exceed the plane where the pivot side of the box body 1 is located, so that the household appliance 100 is applicable to a zero-clearance embedded application scenario, can avoid interference / collision between the door body 2 and the external environmental components, and enable the door body 2 to open / close smoothly.

[0092] In a specific embodiment, the a is 3 mm. Of course, this is not a limitation.

[0093] In summary, in the control method of the door body 2 in the present invention, the rotary drive mechanism 36 automatically drives the door body 2 to rotate relative to the box body 1, which can realize automatic opening / closing of the door without manual operation by the user, facilitating the user to use the household appliance 100; at the same time, the rotary drive mechanism 36 can accurately control the opening angle of the door body. Especially for an embedded household appliance in an embedded application scenario, it can avoid collision between the door body 2 and external environmental components due to an excessive opening angle.
