Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a cooking appliance and a cabinet. Background Technology

[0002] Currently, existing built-in cooking appliances are installed in custom-sized cabinets. The gaps between these appliances and the cabinets are 2.5mm on the sides, 6mm at the top, and 15.5mm at the bottom (the gap between the door and the cooktop legs is 5.5mm, and the cabinet is recessed by 10mm). This results in uneven gaps and an unsightly appearance. The large bottom gap is mainly due to the fixed hinge between the door and the cabinet. During opening and closing, the door rotates downwards around this hinge. To avoid interference between the door and the cabinet, the custom-made cabinet is recessed by 10mm. This also leads to a large gap between the cooking appliance and the cabinet, affecting aesthetics and causing dust accumulation and difficulty in cleaning. Summary of the Invention

[0003] The present invention aims to at least solve the technical problems existing in the prior art or related technologies, such as the large gap between cooking utensils and cabinets affecting aesthetics, and the ease with which dust accumulates and cleaning is difficult.

[0004] Therefore, a first aspect of the present invention provides a cooking utensil.

[0005] A second aspect of the invention also provides a cabinet.

[0006] In view of the above, a first aspect of the present invention provides a cooking appliance, comprising: a door; a housing having an opening; and a hinge mechanism including a sliding groove structure and a plurality of limiting members, wherein one of the limiting members and the sliding groove structure is disposed in the door, and the other is disposed in the housing and located on one side of the opening along a first direction; the sliding groove structure includes a plurality of sliding grooves spaced apart along the first direction; the plurality of limiting members are respectively located in the plurality of sliding grooves and are slidable within the sliding grooves; the door is rotatably connected to the housing through the sliding groove structure and the limiting members to open or close the opening; wherein each sliding groove extends along the first direction to the other side of the opening and along the second direction away from the opening.

[0007] The cooking appliance provided by the present invention includes a door, a housing, and a hinge mechanism. The hinge mechanism includes a sliding groove structure and a limiting member. The sliding groove structure includes a plurality of sliding grooves spaced apart along a first direction. The limiting member is disposed in the sliding groove and can slide within the sliding groove. One of the limiting member and the sliding groove structure is disposed on the door and the other is disposed on the housing. The one on the housing is located on one side of the opening along the first direction, so that the door can be flipped over by the cooperation of the limiting member and the sliding groove structure, thereby opening or closing the opening. The sliding groove extends along the first direction to the other side of the opening and along the second direction away from the opening. As the door opens, guided by multiple sliding grooves and multiple limiting components, the door moves along the first direction to the other side of the opening and along the second direction away from the opening. This avoids interference between the door and the cabinet where the cooking utensils are installed. Therefore, it is not necessary to lower the cabinet to provide the space required for the door to rotate in the first direction. This allows the gap between the door and the cabinet to be set relatively small, making it less prone to dust accumulation and easier to clean. This improves the overall integrity between the cooking utensils and the cabinet and ensures smooth door movement during opening and closing.

[0008] The cooking appliance provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, optionally, when the chute structure is provided in the housing, the chute structure is located at the bottom of the opening along the first direction.

[0010] In this embodiment, when the sliding groove structure is located at the bottom of the opening along the first direction, the limiting member is located on the door, and the door is connected to the bottom of the cabinet, making the door a pull-down door. In this way, when the door opens, the sliding groove and the limiting member cooperate to allow the door to move upward and to the front of the cabinet, thereby avoiding interference between the door and the bottom cabinet and eliminating the need to reserve a large space on the cabinet for the movement of the door.

[0011] In some embodiments, optionally, the slide includes: a first slide segment; and a second slide segment communicating with the first slide segment and disposed at one end of the first slide segment near the opening along a first direction. Both the first slide segment and the second slide segment extend along the first direction toward the top of the housing and along a second direction away from the housing. When the door is closed, a limiting member is located at the end of the first slide segment away from the second slide segment. When the door is at a first opening angle, the limiting member is located at the end of the second slide segment away from the first slide segment. The first slide segment is straight, and the second slide segment is arc-shaped; or both the first slide segment and the second slide segment are arc-shaped, and the arc of the second slide segment is greater than the arc of the first slide segment.

[0012] In this embodiment, the slide rail includes a first groove segment and a second groove segment. The second groove segment is connected to the first groove segment and is located at the end of the first groove segment closer to the opening along a first direction. When the door is closed, the limiting member is located at the end of the first groove segment away from the second groove segment. When the door is at a first opening angle, the limiting member is located at the end of the second groove segment away from the first groove segment. During the opening of the door, the limiting member moves from the first groove segment to the second groove segment. When the first groove segment is straight and the second groove segment is curved, the door rises rapidly while flipping during the opening process, avoiding interference between the door and the cabinet during the door's movement and ensuring the smoothness of the door's opening action. When both the first and second groove segments are curved, the door gradually flips during the rising process. Furthermore, since the curvature of the second groove segment is greater than that of the first groove segment, the outward flipping amplitude of the door increases after the limiting member moves to the second groove segment, allowing the door to open the cabinet.

[0013] In some embodiments, the hinge mechanism may optionally include a damping component disposed in the housing and hinged to the door, wherein the door is capable of moving the damping component to suspend the door at at least a second opening angle when the door is opened.

[0014] In this embodiment, the hinge mechanism further includes a damping component, which is disposed on the housing and hinged to the door. During the movement of the door, the door can drive the damping component to move, and when the damping force generated by the damping component is the same as the torque generated by the weight of the door, the door is suspended at the second opening angle.

[0015] In some embodiments, optionally, the damping component includes: a transmission member, one end of which is rotatably connected to the door body; and an elastic member, both ends of which are respectively connected to the other end of the transmission member and the housing, the transmission member and the elastic member being rotatably connected; during the opening process of the door body, the door body drives the transmission member to move, and the elastic member undergoes elastic deformation to make the door body hover at a second opening angle; during the closing process of the door body, the elastic member restores its deformation to drive the door body to close the opening.

[0016] In this embodiment, the damping component includes a transmission component and an elastic component. The transmission component is connected to the door body and is rotatably connected to the door body. When the door body moves, it can drive the transmission component to move. The two ends of the elastic component are connected to the transmission component and the housing, respectively. During the opening process of the door body, the door body pulls the elastic component through the transmission component, causing the elastic component to extend and generate an elastic force. When the elastic force of the elastic component is equal to the torque generated by the weight of the door body, the door body is suspended at a second opening angle. Correspondingly, during the closing process of the door body, the elastic component returns to its original deformation. When the elastic force of the elastic component is greater than the torque generated by the weight of the door body, the elastic force drives the door body, thereby achieving the effect of automatic door closing.

[0017] In some embodiments, the damping assembly may optionally include: a mounting block connected to the housing; and an adjusting member, one end of which is connected to the end of the elastic member away from the transmission member along the length direction of the elastic member, and the adjusting member and the mounting block are movably connected along the length direction of the elastic member to adjust the initial length of the elastic member.

[0018] In this embodiment, the damping assembly further includes a mounting block and an adjusting member. The mounting block is connected to the housing, and the adjusting member is movably connected to the mounting block and can move relative to the mounting block so that the length of the adjusting member extending out of the mounting block can be adjusted, thereby realizing the adjustment of the initial length of the elastic member, so that the elastic member has different preloads, in order to achieve the tightness of the door closing the housing and to achieve different angles of door suspension.

[0019] In some embodiments, the damping assembly may optionally include a slider, a transmission member and an elastic member connected by the slider, wherein the transmission member is rotatable relative to the slider, and the slider is slidable relative to the housing along the length direction of the elastic member.

[0020] In this embodiment, the damping assembly further includes a sliding member. The elastic member and the transmission member are connected through the sliding member, and the transmission member can rotate relative to the sliding member. The sliding member can slide relative to the housing along the length of the elastic member. The sliding member serves to limit and guide the movement of the damping assembly. During the opening of the door, the transmission member drives the sliding member to slide relative to the housing, and the sliding member drives the elastic member to stretch, thus suspending the door. During the closing of the door, the elastic member recovers its deformation, and the deformation force drives the sliding member to slide relative to the housing, which in turn drives the door to move through the transmission member, providing assistance for closing the door.

[0021] In some embodiments, optionally, the number of elastic elements is at least two, and the at least two elastic elements are connected sequentially along the length direction of the elastic elements.

[0022] In this embodiment, there are at least two elastic elements, which are connected sequentially along the length direction. This increases the stretchable length and rigidity of the elastic elements, enabling them to assist in closing the door and to allow the door to stop during opening.

[0023] In some embodiments, the hinge mechanism may optionally include: a first connector connected to the door body, a limiting member disposed on the first connector; a second connector connected to the housing, a sliding groove structure disposed on the second connector, and a damping assembly disposed on the second connector and rotatably connected to the first connector.

[0024] In this embodiment, the hinge mechanism further includes a first connecting member and a second connecting member. The first connecting member is connected to the door body, and the second connecting member is connected to the housing body. A limiting member is disposed on the first connecting member, and a sliding groove structure is disposed on the second connecting member. The first and second connecting members facilitate the connection between the hinge mechanism and the housing body and door body, simplifying the assembly process and reducing assembly difficulty. The damping component is disposed on the second connecting member, allowing it to be installed on the housing body via the second connecting member, thus facilitating the installation of the damping component.

[0025] In some embodiments, the second connector may optionally include a mounting housing, a damping component disposed within the mounting housing, and a component capable of sliding within the mounting housing.

[0026] In this embodiment, the second connector includes a mounting shell, and the damping component is disposed inside the mounting shell, which can prevent the damping component from being exposed and also provide space for the damping component to slide through the mounting shell.

[0027] In some embodiments, optionally, the slide structure includes: a first plate body disposed on one side of the mounting shell along a third direction; a second plate body disposed on the other side of the mounting shell along a third direction, both the first plate body and the second plate body being provided with a plurality of slide grooves, the slide grooves penetrating the first plate body and the second plate body along a third direction; the mounting shell being provided with a through hole, the through hole communicating with the slide groove; limiting members being disposed on both sides of the first connector along a third direction, a portion of the first connector being located between the first plate body and the second plate body, so that the limiting members on both sides of the first connector are respectively inserted into the slide grooves on the first plate body and the slide grooves on the second plate body.

[0028] In this embodiment, the slide structure includes a first plate and a second plate, which are located on opposite sides of the mounting shell along a third direction. Slides are provided on the first plate and the second plate, and the slides communicate with the through holes on the mounting shell. In this way, the limiting members on both sides of the first connector can be inserted into the slides on the first plate and the second plate, respectively, to achieve the limiting cooperation between the limiting members and the slide structure, thereby improving the reliability of the slide structure in guiding the movement trajectory of the limiting members.

[0029] In some embodiments, the hinge mechanism may optionally include an angle limiting block disposed on the first connector for limiting cooperation with the damping component when the door is at a third opening angle.

[0030] In this embodiment, the hinge mechanism also includes an angle limiting block. When the door is at the third opening angle, the angle limiting block cooperates with the damping component to limit the opening angle so that the first connector and the door are kept at the third opening angle. This allows for dehumidification or ventilation of the cabinet and also prevents the door from closing under the action of the damping component, thereby preventing the door from pinching the user.

[0031] Optionally, the third opening angle is less than the second opening angle, or the third opening angle is equal to the second opening angle.

[0032] In some embodiments, the door body is optionally detachably connected to the first connector.

[0033] In this embodiment, the door body is detachably connected to the first connecting member, allowing the door body to be removed for individual cleaning and improved cleaning efficiency. Specifically, when the door body is at the third opening angle, the angle limiting block and damping component work together to maintain the door body at the third opening angle. This allows for disassembly of the door body at this angle, preventing damage to the damping component and avoiding injury to the user due to movement of the first connecting member during disassembly.

[0034] According to a second aspect of the invention, a cabinet is also provided, comprising: a cabinet body; and a cooking appliance as described in any of the above embodiments, the cooking appliance being embedded in the cabinet body.

[0035] The cabinet provided by the second aspect of the present invention, having included the cooking appliances proposed in any of the above embodiments, thus possesses all the beneficial effects of cooking appliances.

[0049] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0051] The following reference Figures 1 to 9 A cooking appliance 100 and a cabinet are described according to some embodiments of the present invention.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 As shown, according to one embodiment of the present invention, the present invention provides a cooking appliance 100, comprising: a door 1, a housing 2, and a hinge mechanism 3.

[0053] Specifically, the box body 2 is provided with an opening 20; the hinge mechanism 3 includes a sliding groove structure 30 and a plurality of limiting members 32. One of the limiting members 32 and the sliding groove structure 30 is provided on the door body 1, and the other is provided on the box body 2 and located on one side of the opening 20 along the first direction. The sliding groove structure 30 includes a plurality of sliding grooves 301, which are spaced apart along the first direction. The plurality of limiting members 32 are respectively located in the plurality of sliding grooves 301 and can slide in the sliding grooves 301. The door body 1 is rotatably connected to the box body 2 through the sliding groove structure 30 and the limiting members 32 to open or close the opening 20. Each sliding groove 301 extends along the first direction to the other side of the opening 20 and along the second direction away from the opening 20.

[0054] The cooking appliance 100 provided by the present invention includes a door body 1, a housing 2, and a hinge mechanism 3. The hinge mechanism 3 includes a sliding groove structure 30 and a limiting member 32. The sliding groove structure 30 includes a plurality of sliding grooves 301 spaced apart along a first direction. The limiting member 32 is disposed in the sliding groove 301 and can slide within the sliding groove 301. One of the limiting member 32 and the sliding groove structure 30 is disposed on the door body 1, and the other is disposed on the housing 2. The one located on the housing 2 is located on one side of the opening 20 along the first direction, so that the door body 1 can be flipped over by the cooperation of the limiting member 32 and the sliding groove structure 30, thereby opening or closing the opening 20. The sliding groove 301 extends along the first direction to the other side of the opening 20 and along the second direction away from the opening 20. Thus, during the process of the door 1 opening the cabinet 2, under the guidance of multiple sliding grooves 301 and multiple limiting members 32, the door 1 moves along the first direction to the other side of the opening 20 and along the second direction away from the opening 20, avoiding interference between the door 1 and the cabinet where the cooking appliance 100 is installed. Therefore, it is not necessary to lower the cabinet to provide the space required for the door 1 to rotate in the first direction. As a result, the gap between the door 1 and the cabinet can be set relatively small, making it less likely for dust to accumulate in the gap between the door 1 and the cabinet, and making it easier to clean. This improves the integrity between the cooking appliance 100 and the cabinet and ensures the smoothness of the door 1's movement during opening and closing.

[0055] Optionally, the slide 301 includes a first end and a second end, and the slide 301 extends from the first end to the second end in a first direction toward the other side of the opening 20 and in a second direction away from the opening 20. When the door 1 closes the opening 20, the limiting member 32 is close to or located at the first end of the slide 301, and when the door 1 opens the opening 20, the limiting member 32 is close to or located at the second end of the slide 301.

[0056] Optionally, door 1 can be a pull-down door or a side-opening door. When door 1 is a pull-down door, the hinge mechanism 3 is connected to the bottom of the cabinet 2 and the bottom of door 1. The first direction is the height direction of the cabinet 2, and the second direction is the front-back direction of the cabinet 2. During the opening of door 1, the cooperation between multiple sliding grooves 301 and multiple limiting members 32 allows door 1 to move upwards and outwards from the cabinet 2, causing the bottom of door 1 to move upwards and outwards. This prevents interference between the bottom of door 1 and the cabinet during the opening process. During the closing of door 1, guided by the limiting members 32 and the sliding grooves 301, door 1 moves towards the bottom of the cabinet 2 in the first direction and towards the cabinet 2 in the second direction, closing the opening 20.

[0057] It is understandable that by setting multiple sliding grooves 301 and multiple limiting members 32, the door 1 can achieve upward and outward track-changing movement. The movement trajectory of the door 1 is no longer a trajectory around a fixed center, so there is no need to increase the distance between the bottom of the door 1 and the cabinet.

[0058] Optionally, when the door 1 is a side-opening door, the hinge mechanism 3 can be connected to one of the left or right sides of the housing 2.

[0059] Optionally, the contours of the multiple grooves 301 are identical.

[0060] Optionally, there are two slides 301 and two limiting members 32, with one limiting member 32 provided in each slide 301.

[0061] Optionally, the first direction and the second direction are perpendicular.

[0062] In some embodiments, optionally, when the chute structure 30 is provided in the housing 2, the chute structure 30 is located at the bottom of the opening 20 along the first direction.

[0063] In this embodiment, when the sliding groove structure 30 is provided on the cabinet 2, the sliding groove structure 30 is located at the bottom of the opening 20 along the first direction, and the limiting member 32 is provided on the door 1. Thus, the door 1 is connected to the bottom of the cabinet 2, making the door 1 a pull-down door 1. In this way, when the door 1 opens the opening 20, with the cooperation of the sliding groove 301 and the limiting member 32, the door 1 can move upward and to the front of the cabinet 2, thereby avoiding interference between the door 1 and the bottom cabinet, and there is no need to reserve a large space on the cabinet for the movement of the door 1.

[0064] It is understandable that when the chute structure 30 is provided in the housing 2 and is located at the bottom of the opening 20 along the first direction, the chute 301 extends from bottom to top to the outside of the opening 20.

[0065] Optionally, when the door 1 is closed and the opening 20 is closed, the limiting member 32 is located at one end of the slide 301 along the first direction near the bottom of the box 2, and when the door 1 is at the first opening angle, the limiting member 32 is located at one end of the slide 301 along the first direction away from the bottom of the box 2.

[0066] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the chute 301 may optionally include a first chute segment 302 and a second chute segment 303.

[0067] The second groove segment 303 is connected to the first groove segment 302 and is located at the end of the first groove segment 302 near the opening 20 along the first direction. Both the first groove segment 302 and the second groove segment 303 extend towards the top of the box body 2 along the first direction and away from the box body 2 along the second direction. When the door 1 closes the opening 20, the limiting member 32 is located at the end of the first groove segment 302 away from the second groove segment 303. When the door 1 is at the first opening angle, the limiting member 32 is located at the end of the second groove segment 303 away from the first groove segment 302. The first groove segment 302 is straight and the second groove segment 303 is arc-shaped; or both the first groove segment 302 and the second groove segment 303 are arc-shaped, and the arc of the second groove segment 303 is greater than the arc of the first groove segment 302.

[0068] In this embodiment, the slide 301 includes a first groove segment 302 and a second groove segment 303. The second groove segment 303 is connected to the first groove segment 302, and the second groove segment 303 is located at the end of the first groove segment 302 near the opening 20 along a first direction. When the door 1 closes the opening 20, the limiting member 32 is located at the end of the first groove segment 302 away from the second groove segment 303. When the door 1 is at a first opening angle, the limiting member 32 is located at the end of the second groove segment 303 away from the first groove segment 302. During the opening of the door 1, the limiting member 32 moves from the first groove segment 302 to the second groove segment 303. When section 302 is straight and section 303 is curved, the door 1 rises rapidly while flipping during the opening process, which avoids interference between the door 1 and the cabinet during the movement of the door 1 and ensures the smoothness of the opening action of the door 1. When both section 302 and section 303 are curved, the door 1 will gradually flip during the rising process when opening. Furthermore, since the curvature of section 303 is greater than that of section 302, the outward flipping range of the door 1 increases after the limiting member 32 moves to section 303, so that the door 1 opens the cabinet 2.

[0069] It is understandable that the first opening angle is the maximum opening angle of door 1.

[0070] Optionally, the first slot segment 302 and the second slot segment 303 are smoothly connected.

[0071] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the hinge mechanism 3 may optionally include a damping component 36, disposed on the housing 2 and hinged to the door 1, wherein the door 1 can drive the damping component 36 to move so that when the door 1 opens the opening 20, the door 1 is suspended at at least a second opening angle.

[0072] In this embodiment, the hinge mechanism 3 further includes a damping component 36, which is disposed on the housing 2 and hinged to the door 1. During the movement of the door 1, the door 1 can drive the damping component 36 to move. When the damping force generated by the damping component 36 is the same as the torque generated by the weight of the door 1, the door 1 is suspended at the second opening angle.

[0073] Optionally, when the door 1 opens the opening 20, the door 1 can be suspended at any angle when the damping force generated by the damping component 36 is the same as the torque generated by the weight of the door 1.

[0074] Optionally, there may be one or more second opening angles.

[0075] It is understandable that the second opening angle is smaller than the first opening angle.

[0076] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the damping assembly 36 optionally includes a transmission element 361 and an elastic element 362.

[0077] Specifically, one end of the transmission component 361 is rotatably connected to the door body 1; both ends of the elastic component 362 are respectively connected to the other end of the transmission component 361 and the housing 2, and the transmission component 361 and the elastic component 362 are rotatably connected; during the process of the door body 1 opening the opening 20, the door body 1 drives the transmission component 361 to move, and the elastic component 362 undergoes elastic deformation so that the door body 1 is suspended at the second opening angle; during the process of the door body 1 closing the opening 20, the elastic component 362 restores its deformation so that the door body 1 closes the opening 20.

[0078] In this embodiment, the damping component 36 includes a transmission component 361 and an elastic component 362. The transmission component 361 is connected to the door body 1 and is rotatably connected to the door body 1. When the door body 1 moves, it can drive the transmission component 361 to move. The two ends of the elastic component 362 are respectively connected to the transmission component 361 and the housing 2. During the process of the door body 1 opening the opening 20, the door body 1 pulls the elastic component 362 through the transmission component 361, causing the elastic component 362 to extend and generate an elastic force. When the elastic force of the elastic component 362 is equal to the torque generated by the weight of the door body 1, the door body 1 is suspended at the second opening angle. Correspondingly, during the process of the door body 1 closing the opening 20, the elastic component 362 recovers its deformation. Then, when the elastic force of the elastic component 362 is greater than the torque generated by the weight of the door body 1, the elastic force drives the door body 1, thereby achieving the effect of automatic door closing.

[0079] like Figure 4 As shown, in some embodiments, the damping assembly 36 may optionally include: a mounting block 363 connected to the housing 2; and an adjusting member 364, one end of which is connected to the end of the elastic member 362 away from the transmission member 361 along the length direction of the elastic member 362, and the adjusting member 364 and the mounting block 363 are movably connected along the length direction of the elastic member 362 to adjust the initial length of the elastic member 362.

[0080] In this embodiment, the damping assembly 36 further includes a mounting block 363 and an adjusting member 364. The mounting block 363 is connected to the housing 2, and the adjusting member 364 is movably connected to the mounting block 363 and can move relative to the mounting block 363 so that the length of the adjusting member 364 extending out of the mounting block 363 can be adjusted, thereby realizing the adjustment of the initial length of the elastic member 362, so that the elastic member 362 has different preloads, so as to achieve the tightness of the door 1 closing the housing 2, and to achieve different angles of suspension of the door 1.

[0081] Optionally, the adjusting member 364 is slidably connected to the mounting block 363. Specifically, the adjusting member 364 can slide relative to the mounting hole along the length direction of the elastic member 362, thereby allowing the length of the adjusting member 364 extending out of the mounting block 363 to be adjusted.

[0082] Optionally, the mounting block 363 is fixed on the housing 2. The mounting block 363 can be directly mounted on the housing 2 or indirectly mounted on the housing 2 through other structures.

[0083] Optionally, the length direction of the elastic element 362 is the second direction.

[0084] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the damping assembly 36 may optionally include a slider 365, a transmission member 361 and an elastic member 362 connected by the slider 365, and the transmission member 361 is rotatable relative to the slider 365, and the slider 365 is slidable relative to the housing 2 along the length direction of the elastic member 362.

[0085] In this embodiment, the damping assembly 36 further includes a slider 365. The elastic element 362 and the transmission element 361 are connected through the slider 365. The transmission element 361 can rotate relative to the slider 365, and the slider 365 can slide relative to the housing 2 along the length direction of the elastic element 362. The slider 365 serves to limit and guide the movement of the damping assembly 36. During the process of the door 1 opening the opening 20, the transmission element 361 can drive the slider 365 to slide relative to the housing 2, and the slider 365 drives the elastic element 362 to stretch, thus suspending the door 1. During the process of the door 1 closing the opening 20, the elastic element 362 recovers its deformation, and the deformation force drives the slider 365 to slide relative to the housing 2, thereby driving the door 1 to move through the transmission element 361, providing assistance for the closing of the door 1.

[0086] In some embodiments, the number of elastic members 362 is optionally at least two, and at least two elastic members 362 are connected sequentially along the length direction of the elastic members 362.

[0087] In this embodiment, there are at least two elastic elements 362, which are connected sequentially along the length direction. This increases the stretchable length and rigidity of the elastic elements 362, enabling them to assist in closing the door 1 during the closing process and to allow the door 1 to hover during the opening process.

[0088] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the hinge mechanism 3 may optionally include: a first connector 37 connected to the door body 1, a limiting member 32 disposed on the first connector 37; a second connector 38 connected to the housing 2, a sliding groove structure 30 disposed on the second connector 38, and a damping component 36 disposed on the second connector 38 and rotatably connected to the first connector 37.

[0089] In this embodiment, the hinge mechanism 3 further includes a first connecting member 37 and a second connecting member 38. The first connecting member 37 is connected to the door body 1, and the second connecting member 38 is connected to the housing 2. A limiting member 32 is disposed on the first connecting member 37, and a sliding groove structure 30 is disposed on the second connecting member 38. The first connecting member 37 and the second connecting member 38 facilitate the connection between the hinge mechanism 3 and the housing 2 and the door body 1, simplifying the assembly process and reducing assembly difficulty. The damping component 36 is disposed on the second connecting member 38, allowing the damping component 36 to be installed on the housing 2 via the second connecting member 38, thus facilitating the installation of the damping component 36.

[0090] like Figure 7 and Figure 8 As shown, during the opening of door 1, point B on the first connector 37 moves along trajectory L, causing door 1 to move upward and towards the front of the cabinet, thus avoiding interference with the cabinet.

[0091] In some embodiments, the second connector 38 may optionally include a mounting housing 380, a damping component 36 disposed within the mounting housing 380 and slidable within the mounting housing 380.

[0092] In this embodiment, the second connector 38 includes a mounting shell 380, and the damping component 36 is disposed inside the mounting shell 380, which can prevent the damping component 36 from being exposed, and can also provide sliding space for the damping component 36 through the mounting shell 380.

[0093] Optionally, the mounting housing 380 is provided with limiting grooves 384 on both sides, the limiting grooves 384 extending along the length direction of the elastic member 362, and the two ends of the sliding member 365 passing through the limiting grooves 384 on both sides of the mounting housing 380 and being able to slide within the limiting grooves 384 along the length direction of the elastic member 362.

[0094] like Figure 2 As shown, in some embodiments, optionally, the slide groove structure 30 includes: a first plate 304 disposed on one side of the mounting shell 380 along a third direction; a second plate 305 disposed on the other side of the mounting shell 380 along a third direction; both the first plate 304 and the second plate 305 are provided with a plurality of slide grooves 301, which penetrate the first plate 304 and the second plate 305 along a third direction; the mounting shell 380 is provided with a through hole 382, ​​which communicates with the slide groove 301; limiting members 32 are disposed on both sides of the first connecting member 37 along a third direction, and a portion of the first connecting member 37 is located between the first plate 304 and the second plate 305, so that the limiting members 32 on both sides of the first connecting member 37 are respectively inserted into the slide groove 301 on the first plate 304 and the slide groove 301 on the second plate 305.

[0095] In this embodiment, the slide structure 30 includes a first plate 304 and a second plate 305. The first plate 304 and the second plate 305 are respectively located on both sides of the mounting shell 380 along a third direction. The first plate 304 and the second plate 305 are respectively provided with slide grooves 301, and the slide grooves 301 are connected to the through holes 382 on the mounting shell 380. In this way, the limiting members 32 on both sides of the first connector 37 can be inserted into the slide grooves 301 on the first plate 304 and the second plate 305 respectively, realizing the limiting cooperation between the limiting members 32 and the slide structure 30, and improving the reliability of the slide structure 30 in guiding the movement trajectory of the limiting members 32.

[0096] It is understood that the sliding groove 301 on the first plate 304 and the sliding groove 301 on the second plate 305 are arranged opposite to each other along a third direction, and the first plate 304 is provided with a plurality of sliding grooves 301 spaced apart along the first direction, and the second plate 305 is provided with a plurality of sliding grooves 301 spaced apart along the first direction.

[0097] like Figure 4 As shown, in some embodiments, the hinge mechanism 3 may optionally include an angle limiting block 34 disposed on the first connector 37, for limiting and cooperating with the damping component 36 when the door 1 is at the third opening angle.

[0098] In this embodiment, the hinge mechanism 3 also includes an angle limiting block 34. When the door 1 is at the third opening angle, the angle limiting block 34 cooperates with the damping component 36 to limit the opening angle so that the first connector 37 and the door 1 are kept at the third opening angle. This allows for dehumidification or ventilation of the cabinet 2 and also prevents the door 1 from closing under the action of the damping component 36, thereby preventing the door 1 from pinching the user.

[0099] Optionally, the third opening angle is less than the second opening angle, or the third opening angle is equal to the second opening angle.

[0100] Optionally, the angle limiting block 34 is movably connected to the first connecting member 37, so that the angle limiting block 34 and the first connecting member 37 can switch between limiting engagement and unlocking. The user can manually drive the angle limiting block 34 to engage or unlock with the transmission member 361 of the damping assembly 36.

[0101] In some embodiments, the door 1 may be detachably connected to the first connector 37.

[0102] In this embodiment, the door body 1 is detachably connected to the first connecting member 37, allowing the door body 1 to be removed for individual cleaning, thus improving the cleaning effect. Specifically, when the door body 1 is at the third opening angle, the angle limiting block 34 and the damping component 36 engage to limit the door body 1, maintaining it at the third opening angle. This allows the door body 1 to be disassembled while at the third opening angle, preventing damage to the damping component 36 and avoiding injury to the user due to the movement of the first connecting member 37 during disassembly.

[0103] Optionally, the third opening angle includes any value among 5°, 6°, 7°, 8°, 9°, 10°, 15°, and 20°.

[0104] According to one embodiment of the present invention, a cabinet is also provided, comprising: a cabinet body; and a cooking appliance 100 as described in any of the above embodiments, the cooking appliance 100 being embedded in the cabinet body.

[0105] The cabinet provided by the present invention, because it includes the cooking appliance 100 proposed in any of the above embodiments, has all the beneficial effects of the cooking appliance 100.

[0106] Optionally, the cooking appliance 100 includes any one of an oven, a steam oven, a steam oven, a microwave oven, an air fryer, or a microwave air fryer.

[0107] In practical applications, the built-in oven proposed in this application features a sliding door where the bottom of the door 1 moves along a changing track during the opening and closing process, rather than rotating around a fixed axis. This ensures that the door 1 does not interfere with the cabinet body when the gap is small. Simultaneously, it also satisfies the requirements for door opening / closing and smooth door movement.

[0108] For the convenience of movement during the opening and closing of built-in ovens, this embodiment proposes a variable-track hinge mechanism (e.g., hinge mechanism 3) that allows the door 1 to remain suspended without interfering with the cabinet during opening and closing. The hinge mechanism 3 includes a hinge housing (second connecting member 38), a hinge arm (e.g., first connecting member 37), a transmission rod (e.g., transmission member 361), a first connecting pin (e.g., limiting member 32), a second connecting pin, an angle fixing block (e.g., angle limiting block 34), a linear slide groove (e.g., limiting groove 384 on the second connecting member 38), a tension spring (e.g., elastic member 362), a length adjusting rod for the tension spring (e.g., adjusting member 364), a fixing block for the tension spring (e.g., mounting block 363), a countersunk screw, a first track groove, and a second track groove (e.g., first plate 304 and second plate 305).

[0109] Hinged housing: fixed to housing 2 with screws.

[0110] Hinged arm: Connects to the pull-down door of the built-in oven and is fixed to the door body 1 with screws.

[0111] Transmission rod: The hinge arm and the tension spring are connected by a second connecting pin. When the hinge arm moves, it drives the transmission rod to move.

[0112] First connecting pin: connects the hinge arm to the first track groove and the second track groove.

[0113] Second connecting pin: connects the hinge arm and the angle fixing block, the hinge arm and the transmission rod, the transmission rod and the tension spring, and the tension spring and the adjusting rod.

[0114] Angle fixing block: restricts the rotation angle of the hinge arm when the door 1 is opened to a certain angle.

[0115] Linear slide: The sliding component 365 makes a linear limiting movement in the linear slide.

[0116] Tension spring: It is connected to the transmission rod and the length adjustment rod of the tension spring through the second connecting pin, and it extends or retracts as the sliding member 365 moves in the linear slide groove.

[0117] The spring length adjustment rod can adjust the end position and initial length of the spring and is fixed to the hinge housing by a fixing block.

[0118] The tension spring fixing block is fixed to the hinge housing and can adjust the length of the tension spring adjustment rod.

[0119] Countersunk screws: Used to fix the first track groove, the second track groove, and the tension spring fixing block to the hinge housing.

[0120] First track groove and second pair of base grooves: fixed on the hinge housing, and restricting the first connecting pin on the hinge arm to travel a prescribed path in the track groove.

[0121] In the embodiments proposed in this application, the hinge arm is fixed to the door body 1 by screws, and the hinge housing is fixed to the housing 2. The hinge arm moves along a predetermined path in the track groove via a first connecting pin. During the opening and closing of the door body 1, the hinge arm rotates around the second connecting pin and drives the transmission rod to move within the linear slide groove 301. At this time, the tension spring is extended or retracted. When the door body 1 is open, the spring tension provided by the extension spring is equal to the torque generated by the weight of the door body 1, enabling the door body 1 to hover at any angle. During the closing of the door body 1, the spring tension provided by the retraction spring is greater than the torque generated by the weight of the door body 1, enabling the door body 1 to close automatically.

[0122] Ultimately, the bottom of the door 1 moves upward and outward by the movement of the hinge arm in the double groove, instead of moving on a fixed pivot. This ensures that the door 1 does not interfere with the cabinet body during the opening and closing process, and also ensures the smooth movement of the door 1 during the opening and closing process.
