Alternatively, the support is further provided with a containing cavity in communication with the opening, and the cooking appliance further comprises a liquid storage box, which is removably arranged in the containing cavity. Optionally, the door body structure is a water box glass door of an oven.

[0013] In addition, the door body structure according to the above technical scheme of the utility model further has the following additional technical features:

[0014] In some technical solutions, the buffer assembly comprises a first buffer member and a second buffer member, wherein the first buffer member is connected with the door body assembly, and the second buffer member is arranged on the support and is connected with the first buffer member in cooperation; based on the movement of the door body assembly relative to the support, the door body assembly can drive the first buffer member to move relative to the second buffer member.

[0015] In this technical solution, the buffer assembly comprises a first buffer member and a second buffer member, specifically, the first buffer member is connected with the door body assembly, and the second buffer member is arranged on the support and is connected with the first buffer member in cooperation, and specifically, during the movement of the door body assembly relative to the support to open or close the opening, the door body assembly can drive the first buffer member to move relative to the second buffer member to generate a buffer force.

[0016] Specifically, when the door body assembly moves relative to the support to open the opening, i.e. during the movement of the door body assembly to the open position, the first buffer member can be driven to move relative to the second buffer member to generate a buffer force, and the generated buffer force can overcome the gravity acting on the door body assembly, thereby providing a certain resistance to the door body assembly during the opening of the opening, so that the door body assembly is slowly opened, avoiding the impact noise generated by the door body assembly rapidly falling under the action of gravity and impacting the support.

[0017] In addition, when the door body assembly moves relative to the support to close the opening, i.e. during the movement of the door body assembly to the closed position, the first buffer member can be driven to move relative to the second buffer member to generate a buffer force, and the generated buffer force can hinder the movement of the door body assembly to the closed position, so that the door body assembly is slowly closed, avoiding the impact noise generated by the door body assembly impacting the support at a relatively large speed.

[0018] In some technical solutions, optionally, the second buffer member comprises a buffer cavity, one end of the first buffer member is connected with the door body assembly, and the other end of the first buffer member is located in the buffer cavity and can move in the buffer cavity to change the volume of the buffer cavity.

[0019] In this technical solution, it is specified that the second buffer member comprises a buffer cavity, specifically, one end of the first buffer member is connected with the door body assembly, and the other end of the first buffer member is located in the buffer cavity.

[0020] Specifically, when the door body assembly moves to the open position, the first buffer member moves relative to the second buffer member, and when the door body assembly moves to a certain position, the volume of the buffer cavity decreases, thereby generating a certain buffer force on the door body assembly, and the buffer force can overcome the gravity acting on the door body assembly, thereby providing a certain resistance to the door body assembly during the opening of the opening, so that the door body assembly is slowly opened.

[0021] In addition, when the door body assembly moves to the closed position, the first buffer member moves relative to the second buffer member, and when the door body assembly moves to a certain position, the volume of the buffer cavity decreases, thereby generating a certain buffer force on the door body assembly, and the buffer force can hinder the movement of the door body assembly to the closed position, so that the door body assembly is slowly closed, avoiding the impact noise generated by the door body assembly impacting the support at a relatively large speed.

[0022] Optionally, the buffer cavity has a buffer medium, wherein the buffer medium comprises a liquid, i.e. the first buffer member and the second buffer member constitute a hydraulic damper, or the buffer medium comprises a gas.

[0023] In some embodiments, the door body assembly is movable relative to the support between a first position and a second position, the opening is closed based on the door body assembly being in the first position, and the opening is opened based on the door body assembly being in the second position; the door body assembly is further movable to a third position between the first position and the second position, the first buffer member moves away from the second buffer member during movement of the door body assembly from the first position to the third position, the buffer cavity has a first volume, and the first buffer member moves towards the second buffer member during movement of the door body assembly from the third position to the second position, the buffer cavity has a second volume, and the second volume is smaller than the first volume.

[0024] In this embodiment, the opening is closed when the door body assembly is in the first position, i.e., the first position is a closed position, and the opening is opened when the door body assembly is in the second position, i.e., the second position is an open position. The third position is between the first position and the second position, and it can be understood that the door body assembly passes through the first position, the third position and the second position in sequence when the door body assembly moves towards the open position, and the door body assembly passes through the second position, the third position and the first position in sequence when the door body assembly moves towards the closed position, i.e., the third position is an intermediate position.

[0025] In detail, when the door body assembly moves towards the open position, the first buffer member moves away from the second buffer member during movement of the door body assembly from the first position to the third position, the volume of the buffer cavity increases, the resistance of the first buffer member is small or no resistance when the first buffer member moves, and the door body assembly can be quickly opened from the first position to the third position. The door body assembly continues to move, i.e., moves from the third position to the second position, the first buffer member moves towards the second buffer member, the volume of the buffer cavity decreases, and thus the resistance of the door body assembly to continue to move is significantly increased, the door body assembly is slowly opened, the door body assembly is effectively prevented from being quickly lowered and hitting the support due to gravity in the latter half of the opening (from the third position to the second position), vibration and noise generated when the door body assembly is opened are significantly improved, and the user's experience of opening and closing the door body is improved.

[0026] In some embodiments, the first buffer member moves away from the second buffer member during movement of the door body assembly from the second position to the third position, the buffer cavity has a third volume, the first buffer member moves towards the second buffer member during movement of the door body assembly from the third position to the first position, the buffer cavity has a fourth volume, and the fourth volume is smaller than the third volume.

[0027] In the technical solution, when the door body assembly moves to the closed position, in the process that the door body assembly moves from the second position to the third position, the first buffer moves away from the second buffer, the volume of the buffer cavity increases, the resistance of the first buffer is small or no resistance when the first buffer moves, and the door body assembly can quickly move from the second position to the third position. When the door body assembly continues to move, that is, in the process that the door body assembly moves from the third position to the first position, the first buffer moves towards the second buffer, the volume of the buffer cavity decreases, and the resistance of the door body assembly to continue to move is significantly increased, so that the door body assembly slowly closes, effectively avoids the door body assembly from impacting the support at a large speed due to the magnetic force in the latter half of the closing process (from the third position to the first position), significantly improves the vibration and noise generated when the door body assembly is closed, and is beneficial to improving the opening and closing experience of the user.

[0028] In some technical solutions, optionally, the door body assembly comprises a door body, a connecting piece and a third connecting shaft, wherein the door body comprises a first end and a second end, one end of the connecting piece is rotatably connected to the first buffer through the first connecting shaft, the other end of the connecting piece is rotatably connected to the door body through the second connecting shaft, and the first end or the second end is rotatably connected to the support through the third connecting shaft; based on the door body being located at the third position, the central axis of the first connecting shaft, the central axis of the second connecting shaft and the central axis of the third connecting shaft are located in the same plane.

[0029] In the technical solution, it is defined that the door body assembly comprises a door body, a connecting piece and a third connecting shaft, specifically, one end of the connecting piece is rotatably connected to the first buffer through the first connecting shaft, the other end of the connecting piece is rotatably connected to the door body through the second connecting shaft, and the door body is rotatably connected to the support through the third connecting shaft, when the central axis of the first connecting shaft, the central axis of the second connecting shaft and the central axis of the third connecting shaft are located in the same plane, the door body is located at the third position, that is, the middle position, and the plane is a critical surface.

[0030] It can be understood that, in the process that the door body assembly moves relative to the support to open or close the opening, when the second connecting shaft moves to the side close to the critical surface, the first buffer moves away from the second buffer, the volume of the buffer cavity increases, and the resistance of the first buffer when moving is small or no resistance. When the second connecting shaft moves to the position of the critical surface and continues to move away from the side where the critical surface is located, the first buffer moves towards the second buffer, the volume of the buffer cavity decreases, and the resistance of the first buffer when moving is significantly increased.

[0031] In some technical solutions, optionally, the first end is closer to the bottom of the support than the second end, and the first end is rotatably connected to the support through the third connecting shaft; wherein the door body is further provided with a connecting part, the connecting part is rotatably connected to the connecting piece through the second connecting shaft, and the connecting part is configured to be close to the first end.

[0032] In the technical solution, the first end is close to the bottom of the support, and the first end is rotationally connected with the support, that is, the door body assembly is a downward opening and closing door.

[0033] The door body is further provided with a connecting portion, which is rotationally connected with the other end of the connecting piece through a second connecting shaft. The connecting portion is close to the first end, that is, the connecting portion is close to the connecting end of the door body and the support, thereby ensuring smooth opening and closing of the door body assembly.

[0034] In some technical solutions, optionally, the first buffer member includes a sliding block, the second buffer member includes a guide rail and a compression portion, wherein the sliding block is slidingly connected with the guide rail, the compression portion is connected with the support, the compression portion includes a first elastic member, the first elastic member is located on the side of the sliding block away from the guide rail and in contact with the sliding block, and the first elastic member is compressed.

[0035] In the technical solution, another buffering mode is defined. Specifically, the second buffer member includes a guide rail and a compression portion, wherein the sliding block is slidingly connected with the guide rail, and the sliding block is connected with the door body assembly, that is, when the door body assembly moves relative to the support to open or close the opening, the door body assembly can drive the sliding block to move relative to the guide rail.

[0036] The compression portion includes a first elastic member, which is in contact with the side of the sliding block away from the guide rail. Since the first elastic member is compressed, the sliding block is pressed on the guide rail under the action of the elastic force of the first elastic member, and thus during the movement of the sliding block relative to the guide rail driven by the door body assembly, the sliding block and the guide rail have a large friction force, and under the action of the friction force, the door body assembly realizes slow opening and closing function, which is beneficial to improve the user's opening and closing experience.

[0037] In some technical solutions, optionally, the compression portion further includes a screw rod and a nut, wherein the screw rod is connected with the support, the first elastic member is arranged on the screw rod, and the nut is arranged on the screw rod and located on the side of the first elastic member away from the sliding block.

[0038] In the technical solution, the compression portion further includes a screw rod and a nut, specifically, the screw rod is connected with the support, the first elastic member is sleeved on the screw rod, and the nut is arranged on the screw rod and located on the side of the first elastic member away from the sliding block, that is, the first elastic member is located between the nut and the sliding block. The length of the first elastic member can be adjusted by the nut and the screw rod, so as to adjust the friction force between the sliding block and the guide rail.

[0039] Optionally, the first elastic member includes a spring.

[0040] In some technical solutions, optionally, the buffer assembly includes a second elastic member, which can be deformed based on the movement of the door body assembly relative to the support.

[0041] In the technical solution, another buffering mode is defined. Specifically, when the door body assembly moves to the opening position, and when the door body assembly moves to a certain position, the second elastic member is deformed (e.g., stretched) to generate a buffering force. It can be understood that the buffering force is an elastic force that can resist the gravity of the door body assembly, thereby providing a certain resistance to the door body assembly during the opening of the opening, allowing the door body assembly to open slowly, avoiding the impact noise generated by the door body assembly rapidly falling under the action of gravity and impacting the support.

[0042] In addition, when the door body assembly moves to the closing position, and when the door body assembly moves to a certain position, the second elastic member is deformed (e.g., compressed) to generate an elastic force that can resist the movement of the door body assembly to the closing position, allowing the door body assembly to close slowly, avoiding the impact noise generated by the door body assembly impacting the support at a high speed.

[0043] Optionally, the second elastic member includes a spring.

[0044] In some technical solutions, at least part of the buffering assembly extends in the height direction of the support; or at least part of the buffering assembly extends obliquely.

[0045] In the technical solution, at least part of the buffering assembly extends in the height direction of the support, that is, during the movement of the door body assembly relative to the support to open or close the opening, the door body assembly can drive at least part of the buffering assembly to move longitudinally, thereby generating a longitudinal buffering force. It can be understood that the longitudinal buffering force can effectively overcome the gravity of the door body assembly during the opening or closing process, achieving the effect of slow opening and slow closing.

[0046] At least part of the buffering assembly extends obliquely, that is, during the movement of the door body assembly relative to the support to open or close the opening, the door body assembly can drive at least part of the buffering assembly to move in an oblique direction, thereby generating an oblique buffering force. It can be understood that the oblique buffering force has a longitudinal component that can overcome the gravity of the door body assembly during the opening or closing process, achieving the effect of slow opening and slow closing.

[0047] In some technical solutions, the door body structure further includes a magnetic member and a cooperating member, wherein the magnetic member is arranged on one of the support and the door body assembly, and the cooperating member is arranged on the other one of the support and the door body assembly, and the cooperating member can be magnetically attracted or separated from the magnetic member.

[0048] In the technical solution, the door body structure further comprises a magnetic member and a cooperating member, specifically, the magnetic member is arranged on the support, and the cooperating member is arranged on the door body assembly. Alternatively, the magnetic member is arranged on the door body assembly, and the cooperating member is arranged on the support. Specifically, the arrangement can be made according to actual needs. Optionally, in the case where the magnetic member is arranged on the door body assembly, the magnetic member is arranged on the inner surface of the door body assembly. In the case where the cooperating member is arranged on the door body assembly, the cooperating member is arranged on the inner surface of the door body assembly, so as to ensure the closing effect of the door body assembly and realize the consistency of the appearance of the door body structure.

[0049] Since the magnetic member can be magnetically attracted to or separated from the cooperating member, specifically, when the opening needs to be opened, the door body assembly is operated to move to the opening position, the magnetic member and the cooperating member are separated from the adsorption, and are separated, the buffering force generated by the buffering assembly can overcome the gravity acting on the door body assembly, so as to provide a certain resistance for the door body assembly during the opening of the opening, and the door body assembly is slowly opened.

[0050] When the opening needs to be closed, the door body assembly is operated to move to the closing position, the buffering force generated by the buffering assembly can hinder the movement of the door body assembly to the closing position, so that the door body assembly is slowly closed, and the door body assembly is prevented from impacting the support at a large speed due to the attraction of the magnetic member and the cooperating member. When the door body assembly is located at the closing position, the magnetic member and the cooperating member are magnetically attracted to each other, so as to ensure the closing effect.

[0051] By arranging the magnetic member and the cooperating member, the effective opening and closing of the door body assembly are realized, and the appearance effect of the door body structure is ensured, which is beneficial to improving the overall quality of the product.

[0052] Optionally, in the case where the magnetic member is arranged on the door body assembly, the magnetic member is arranged close to the second end based on the first end being movably connected to the support, and the magnetic member is arranged close to the first end based on the second end being movably connected to the support, so as to ensure that the door body assembly completely closes the opening.

[0053] Optionally, one of the magnetic member and the cooperating member is a magnet, and the other is a magnetic sheet.

[0054] Optionally, one of the magnetic member and the cooperating member is a magnet, and the other is a metal member.

[0059] In the embodiments, the bracket further comprises a receiving cavity, and the receiving cavity is in communication with the opening, and the liquid storage box is detachably arranged in the receiving cavity.

[0060] Specifically, when the liquid storage box needs to be taken out, the door body assembly moves to the opening position to open the opening, and the door body assembly drives at least part of the buffer assembly to generate a buffer force, the buffer force can overcome the gravity acting on the door body assembly, so as to provide a certain resistance for the door body assembly during opening of the opening, and the door body assembly is slowly opened to avoid impact noise caused by the door body assembly rapidly falling under the action of gravity and impacting the bracket.

[0061] When the liquid storage box is filled with liquid and placed in the receiving cavity through the opening, the door body assembly moves to the closing position to close the opening, and the door body assembly drives at least part of the buffer assembly to generate a buffer force, the buffer force can hinder the movement of the door body assembly to the closing position, so as to slowly close the door body assembly to avoid impact noise caused by the door body assembly impacting the bracket at a high speed.

DETAILED DESCRIPTION

[0077] In order to more clearly understand the above purpose, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0078] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0079] The following description will be made with reference toFigures 1 to 9 The door body structure 100 and the cooking appliance provided according to some embodiments of the present application are described.

[0080] In an embodiment according to the present application, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 A door body structure 100 is provided, which comprises a support 110 provided with an opening 111; a door body assembly 120, along the height direction of the support 110, the door body assembly 120 comprises a first end 170 and a second end 180, the first end 170 is movably connected with the support 110, or the second end 180 is movably connected with the support 110, the door body assembly 120 can move relative to the support 110 to open or close the opening 111; a buffer assembly 210 is arranged on the support 110 and connected with the door body assembly 120; wherein, based on the movement of the door body assembly 120 relative to the support 110, the door body assembly 120 can drive at least part of the buffer assembly 210 to move.

[0081] The door body structure 100 provided by the embodiments of the present application comprises a support 110, a door body assembly 120 and a buffer assembly 210. Specifically, along the height direction of the support 110, the door body assembly 120 comprises a first end 170 and a second end 180. Optionally, the first end 170 is the bottom end and the second end 180 is the top end. The first end 170 is movably connected with the support 110, that is, the bottom end is movably connected with the support 110. Optionally, the door body assembly 120 is a downward opening and closing door. Alternatively, the second end 180 is movably connected with the support 110, that is, the top end is movably connected with the support 110. Optionally, the door body assembly 120 is an upward opening and closing door.

[0082] The buffer assembly 210 is arranged on the support 110 and connected with the door body assembly 120. During the movement of the door body assembly 120 relative to the support 110 to open or close the opening 111, the door body assembly 120 can drive at least part of the buffer assembly 210 to move. It can be understood that the movement of at least part of the buffer assembly 210 can generate a buffer force.

[0083] The following example of a switch door is a door body assembly 120 that is movably connected to the support 110 at the bottom end. Specifically, when the door body assembly 120 moves relative to the support 110 to open the opening 111, that is, during the movement of the door body assembly 120 to the open position, at least part of the buffer assembly 210 can be moved to generate a buffer force. The buffer force generated by the buffer assembly 210 can overcome the gravitational force acting on the door body assembly 120, thereby providing a certain resistance to the door body assembly 120 during the opening of the opening 111, allowing the door body assembly 120 to open slowly, avoiding the impact noise caused by the rapid descent of the door body assembly 120 under the action of gravity and the impact with the support 110.

[0084] In addition, when the door body assembly 120 moves relative to the support 110 to close the opening 111, that is, during the movement of the door body assembly 120 to the closed position, at least part of the buffer assembly 210 can be moved to generate a buffer force. The buffer force generated by the buffer assembly 210 can hinder the movement of the door body assembly 120 to the closed position, allowing the door body assembly 120 to close slowly, avoiding the impact noise caused by the impact of the door body assembly 120 on the support 110 at a relatively high speed.

[0085] By providing the buffer assembly 210, the slow opening and closing functions of the door body assembly 120 can be achieved, significantly improving the vibration and noise generated during the opening and closing of the door body assembly 120, and facilitating the improvement of the user's opening and closing experience of the door body structure 100.

Optionally, the door body structure 100 is the oven door of an oven. Alternatively, the support 110 is further provided with a receiving cavity 112 that is in communication with the opening 111, and the cooking appliance further includes a liquid storage box that is removably arranged in the receiving cavity 112. Optionally, the door body structure 100 is the water box glass door of an oven.

[0087] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 , in some embodiments, the buffer assembly 210 includes a first buffer member 130 and a second buffer member 140, wherein the first buffer member 130 is connected to the door body assembly 120, and the second buffer member 140 is arranged on the support 110 and is movably connected with the first buffer member 130; based on the movement of the door body assembly 120 relative to the support 110, the door body assembly 120 can drive the first buffer member 130 to move relative to the second buffer member 140.

[0088] In this embodiment, the buffer assembly 210 is defined to include the first buffer 130 and the second buffer 140, specifically, the first buffer 130 is connected with the door body assembly 120, and the second buffer 140 is arranged on the support 110 and cooperatively connected with the first buffer 130, specifically, during the movement of the door body assembly 120 relative to the support 110 to open or close the opening 111, the door body assembly 120 can drive the first buffer 130 to move relative to the second buffer 140 to generate a buffer force.

[0089] Specifically, during the movement of the door body assembly 120 relative to the support 110 to open the opening 111, i.e. the movement of the door body assembly 120 to the open position, the first buffer 130 can be driven to move relative to the second buffer 140 to generate a buffer force, and the generated buffer force can overcome the gravity acting on the door body assembly 120, thereby providing a certain resistance for the door body assembly 120 during the opening of the opening 111, so that the door body assembly 120 is slowly opened, avoiding the impact noise generated by the rapid falling of the door body assembly 120 under the action of gravity and the support 110.

[0090] In addition, during the movement of the door body assembly 120 relative to the support 110 to close the opening 111, i.e. the movement of the door body assembly 120 to the closed position, the first buffer 130 can be driven to move relative to the second buffer 140 to generate a buffer force, and the generated buffer force can hinder the movement of the door body assembly 120 to the closed position, so that the door body assembly 120 is slowly closed, avoiding the impact noise generated by the impact of the door body assembly 120 on the support 110 at a relatively large speed.

[0091] In some embodiments, optionally, the second buffer 140 includes a buffer cavity, one end of the first buffer 130 is connected with the door body assembly 120, and the other end of the first buffer 130 is located in the buffer cavity and can move in the buffer cavity to change the volume of the buffer cavity.

[0092] In this embodiment, the second buffer 140 is defined to include a buffer cavity, specifically, one end of the first buffer 130 is connected with the door body assembly 120, and the other end of the first buffer 130 is located in the buffer cavity.

[0093] Specifically, during the movement of the door body assembly 120 to the open position, the first buffer 130 moves relative to the second buffer 140, and when the door body assembly 120 moves to a certain position, the volume of the buffer cavity is reduced, thereby generating a certain buffer force on the door body assembly 120, and the buffer force can overcome the gravity acting on the door body assembly 120, thereby providing a certain resistance for the door body assembly 120 during the opening of the opening 111, so that the door body assembly 120 is slowly opened.

[0094] In addition, when the door assembly 120 moves towards the closed position, the first buffer 130 moves relative to the second buffer 140, and when the door assembly 120 moves to a certain position, the volume in the buffer cavity is reduced, thereby generating a certain buffer force on the door assembly 120, which can hinder the movement of the door assembly 120 towards the closed position, so that the door assembly 120 slowly closes, avoiding the impact noise generated by the door assembly 120 impacting the support 110 at a large speed.

[0095] Optionally, the buffer cavity has a buffer medium, wherein the buffer medium includes a liquid, that is, the first buffer 130 and the second buffer 140 constitute a hydraulic damper, or the buffer medium includes a gas.

[0096] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, the door assembly 120 can move relative to the support 110 between a first position and a second position, based on the door assembly 120 being in the first position, the opening 111 is closed, based on the door assembly 120 being in the second position, the opening 111 is opened; the door assembly 120 can also move to a third position between the first position and the second position, during the movement of the door assembly 120 from the first position to the third position, the first buffer 130 moves away from the second buffer 140, the buffer cavity has a first volume, during the movement of the door assembly 120 from the third position to the second position, the first buffer 130 moves towards the second buffer 140, the buffer cavity has a second volume, and the second volume is smaller than the first volume.

[0097] In this embodiment, when the door assembly 120 is in the first position, the opening 111 is closed, that is, the first position is the closed position, as shown in Figure 4 and Figure 5 , when the door assembly 120 is in the second position, the opening 111 is opened, that is, the second position is the open position, as shown in Figure 2 , Figure 3 , Figure 6 and Figure 7 . The third position is between the first position and the second position, and it can be understood that when the door assembly 120 moves towards the open position, the door assembly 120 passes through the first position, the third position and the second position in sequence, and when the door assembly 120 moves towards the closed position, the door assembly 120 passes through the second position, the third position and the first position in sequence, that is, the third position is an intermediate position, as shown in Figure 1 .

[0098] In detail, when the door body assembly 120 moves to the open position, during the movement of the door body assembly 120 from the first position to the third position, the first buffer 130 moves away from the second buffer 140, the volume of the buffer cavity increases, and the resistance of the first buffer 130 is small or no resistance when the first buffer 130 moves, so that the door body assembly 120 can quickly open from the first position to the third position. When the door body assembly 120 continues to move, i.e., during the movement of the door body assembly 120 from the third position to the second position, the first buffer 130 moves towards the second buffer 140, the volume of the buffer cavity decreases, thereby significantly increasing the resistance of the door body assembly 120 to continue to move, so that the door body assembly 120 slowly opens, effectively avoiding the door body assembly 120 from quickly falling and impacting the support 110 due to gravity during the latter half of the opening (from the third position to the second position), significantly improving the vibration and noise generated when the door body assembly 120 is opened, and being beneficial to improving the user's opening and closing experience.

[0099] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , in some embodiments, optionally, during the movement of the door body assembly 120 from the second position to the third position, the first buffer 130 moves away from the second buffer 140, the buffer cavity has a third volume, and during the movement of the door body assembly 120 from the third position to the first position, the first buffer 130 moves towards the second buffer 140, and the buffer cavity has a fourth volume, and the fourth volume is smaller than the third volume.

[0100] In this embodiment, when the door body assembly 120 moves to the closed position, during the movement of the door body assembly 120 from the second position to the third position, the first buffer 130 moves away from the second buffer 140, the volume of the buffer cavity increases, and the resistance of the first buffer 130 is small or no resistance when the first buffer 130 moves, so that the door body assembly 120 can quickly close from the second position to the third position. When the door body assembly 120 continues to move, i.e., during the movement of the door body assembly 120 from the third position to the first position, the first buffer 130 moves towards the second buffer 140, the volume of the buffer cavity decreases, thereby significantly increasing the resistance of the door body assembly 120 to continue to move, so that the door body assembly 120 slowly closes, effectively avoiding the door body assembly 120 from impacting the support 110 at a large speed due to the magnetic force during the latter half of the closing (from the third position to the first position), significantly improving the vibration and noise generated when the door body assembly 120 is closed, and being beneficial to improving the user's opening and closing experience.

[0101] As shown in Figure 1As shown, in some embodiments, optionally, the door assembly 120 includes a door body 121, a connector 122, and a third connecting shaft 125. The door body 121 includes a first end 170 and a second end 180. One end of the connector 122 is rotatably connected to the first buffer member 130 via the first connecting shaft 123, and the other end of the connector 122 is rotatably connected to the door body 121 via the second connecting shaft 124. The first end 170 or the second end 180 is rotatably connected to the bracket 110 via the third connecting shaft 125. Based on the door body 121 being located in the third position, the central axis of the first connecting shaft 123, the central axis of the second connecting shaft 124, and the central axis of the third connecting shaft 125 are located in the same plane.

[0102] In this embodiment, the door assembly 120 is defined as including a door 121, a connector 122, and a third connecting shaft 125. Specifically, one end of the connector 122 is rotatably connected to the first buffer 130 via the first connecting shaft 123, and the other end of the connector 122 is rotatably connected to the door 121 via the second connecting shaft 124. The door 121 is rotatably connected to the bracket 110 via the third connecting shaft 125. When the central axis of the first connecting shaft 123, the central axis of the second connecting shaft 124, and the central axis of the third connecting shaft 125 are located in the same plane, the door 121 is located in the third position, that is, the middle position. This plane is the critical plane 190.

[0103] Understandably, during the movement of the door assembly 120 relative to the bracket 110 to open or close the opening 111, when the second connecting shaft 124 moves towards the side where the critical surface 190 is located, the first buffer member 130 moves away from the second buffer member 140, increasing the volume of the buffer cavity and reducing or eliminating resistance during the movement of the first buffer member 130. When the second connecting shaft 124 moves to the position of the critical surface 190 and continues to move away from the side where the critical surface 190 is located, the first buffer member 130 moves towards the second buffer member 140, decreasing the volume of the buffer cavity and significantly increasing resistance during the movement of the first buffer member 130.

[0104] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the first end 170 is closer to the bottom of the bracket 110 than the second end 180, and the first end 170 is rotatably connected to the bracket 110 via a third connecting shaft 125; wherein, the door body 121 is also provided with a connecting part 126, the connecting part 126 is rotatably connected to the connector 122 via a second connecting shaft 124, and the connecting part 126 is configured to be close to the first end 170.

[0105] In this embodiment, the first end 170 is close to the bottom of the bracket 110, and the first end 170 is rotatably connected to the bracket 110, that is, the door assembly 120 is a flip-down door.

[0106] The door body 121 is also provided with a connecting part 126, which is rotatably connected to the other end of the connector 122 via a second connecting shaft 124. The connecting part 126 is close to the first end 170, that is, the connecting part 126 is close to the connection end between the door body 121 and the bracket 110, thereby ensuring that the door assembly 120 can be opened and closed smoothly.

[0107] like Figure 9 As shown, in some embodiments, optionally, the first buffer 130 includes a slider 131, and the second buffer 140 includes a guide rail 141 and a pressing part 142, wherein the slider 131 is slidably connected to the guide rail 141, the pressing part 142 is connected to the bracket 110, and the pressing part 142 includes a first elastic member 143, which is located on the side of the slider 131 away from the guide rail 141 and is in contact with the slider 131, and the first elastic member 143 is compressed.

[0108] In this embodiment, another buffering method is defined. Specifically, the second buffer 140 includes a guide rail 141 and a pressing part 142, wherein the slider 131 is slidably engaged with the guide rail 141, and the slider 131 is connected to the door assembly 120. That is, when the door assembly 120 moves relative to the bracket 110 to open or close the opening 111, the door assembly 120 can drive the slider 131 to move relative to the guide rail 141.

[0109] The pressing part 142 includes a first elastic element 143, which contacts the side of the slider 131 away from the guide rail 141. As the first elastic element 143 is compressed, the slider 131 is pressed against the guide rail 141 under the action of the elastic force of the first elastic element 143. As a result, during the process of the door assembly 120 driving the slider 131 to move relative to the guide rail 141, there is a large friction between the slider 131 and the guide rail 141. Under the action of the friction, the door assembly 120 realizes the function of slow opening and slow closing, which helps to improve the user's door opening and closing experience.

[0110] like Figure 9 As shown, in some embodiments, the clamping part 142 may optionally include a screw 144 and a nut 145, wherein the screw 144 is connected to the bracket 110, the first elastic member 143 is disposed on the screw 144, and the nut 145 is disposed on the screw 144 and located on the side of the first elastic member 143 away from the slider 131.

[0111] In this embodiment, the compression part 142 further comprises a screw rod 144 and a nut 145. Specifically, the screw rod 144 is connected to the bracket 110, the first elastic member 143 is sleeved on the screw rod 144, and the nut 145 is arranged on the screw rod 144 and located on the side of the first elastic member 143 away from the sliding block 131, that is, the first elastic member 143 is located between the nut 145 and the sliding block 131. The length of the first elastic member 143 can be adjusted by the nut 145 and the screw rod 144, so as to adjust the friction force between the sliding block 131 and the guide rail 141.

[0112] Optionally, the first elastic member 143 comprises a spring.

[0113] In some embodiments, the buffer assembly 210 comprises a second elastic member, which can be deformed based on the movement of the door body assembly 120 relative to the bracket 110.

[0114] In this embodiment, another buffering mode is defined. Specifically, when the door body assembly 120 moves to the opening position, and when the door body assembly 120 moves to a certain position, the second elastic member is deformed (e.g., stretched) to generate a buffering force. It can be understood that the buffering force is an elastic force, which can resist the gravity of the door body assembly 120, so as to provide a certain resistance to the door body assembly 120 during the opening of the opening 111, so that the door body assembly 120 is slowly opened, avoiding the impact noise generated by the door body assembly 120 rapidly falling under the action of gravity and impacting the bracket 110.

[0115] In addition, when the door body assembly 120 moves to the closing position, and when the door body assembly 120 moves to a certain position, the second elastic member is deformed (e.g., compressed) to generate an elastic force, which can resist the movement of the door body assembly 120 to the closing position, so that the door body assembly 120 is slowly closed, avoiding the impact noise generated by the door body assembly 120 impacting the bracket 110 at a relatively large speed.

[0116] Optionally, the second elastic member comprises a spring.

[0117] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 indicate that, in some embodiments, at least a part of the buffer assembly 210 extends along the height direction of the bracket 110; or at least a part of the buffer assembly 210 extends obliquely.

[0118] In this embodiment, at least part of the buffering assembly 210 extends along the height direction of the bracket 110, that is, during the movement of the door body assembly 120 relative to the bracket 110 to open or close the opening 111, the door body assembly 120 can drive at least part of the buffering assembly 210 to move in the longitudinal direction, thereby generating a buffering force in the longitudinal direction. It can be understood that the buffering force in the longitudinal direction can effectively overcome the gravity of the door body assembly 120 during the opening or closing process, thereby achieving the effects of slow opening and slow closing, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 .

[0119] As shown in Figure 6 and Figure 7 , at least part of the buffering assembly 210 extends obliquely, that is, during the movement of the door body assembly 120 relative to the bracket 110 to open or close the opening 111, the door body assembly 120 can drive at least part of the buffering assembly 210 to move in the oblique direction, thereby generating a buffering force in the oblique direction. It can be understood that the buffering force in the oblique direction has a component in the longitudinal direction, and the component in the longitudinal direction can overcome the gravity of the door body assembly 120 during the opening or closing process, thereby achieving the effects of slow opening and slow closing.

[0120] As shown in Figure 8 , in some embodiments, the door body structure 100 further comprises a magnetic member 150 and a cooperating member 160, wherein the magnetic member 150 is arranged on one of the bracket 110 and the door body assembly 120, and the cooperating member 160 is arranged on the other one of the bracket 110 and the door body assembly 120, and the cooperating member 160 can be magnetically attracted or separated from the magnetic member 150.

[0121] In this embodiment, it is defined that the door body structure 100 further comprises a magnetic member 150 and a cooperating member 160, specifically, the magnetic member 150 is arranged on the bracket 110, and the cooperating member 160 is arranged on the door body assembly 120. Alternatively, the magnetic member 150 is arranged on the door body assembly 120, and the cooperating member 160 is arranged on the bracket 110. Specifically, it can be arranged according to actual needs. Optionally, in the case where the magnetic member 150 is arranged on the door body assembly 120, the magnetic member 150 is arranged on the inner surface of the door body assembly 120. In the case where the cooperating member 160 is arranged on the door body assembly 120, the cooperating member 160 is arranged on the inner surface of the door body assembly 120, so as to ensure the closing effect of the door body assembly 120 while realizing the consistency of the appearance of the door body structure 100.

[0122] Since the magnetic member 150 can be magnetically attracted to or separated from the cooperating member 160, specifically, when it is required to open the opening 111, the door body assembly 120 is moved to the opening position, the magnetic member 150 and the cooperating member 160 are separated from the attraction, and are separated, the buffering force generated by the buffer assembly 210 can overcome the gravity acting on the door body assembly 120, thereby providing a certain resistance to the door body assembly 120 during the opening of the opening 111, so that the door body assembly 120 is slowly opened.

[0123] When it is required to close the opening 111, the door body assembly 120 is moved to the closing position, the buffering force generated by the buffer assembly 210 can hinder the movement of the door body assembly 120 to the closing position, so that the door body assembly 120 is slowly closed, avoiding the impact of the door body assembly 120 on the support 110 at a large speed due to the attraction of the magnetic member 150 and the cooperating member 160. When the door body assembly 120 is located at the closing position, the magnetic member 150 and the cooperating member 160 are magnetically attracted to each other, ensuring the closing effect.

[0124] By arranging the magnetic member 150 and the cooperating member 160, the effective opening and closing of the door body assembly 120 is realized, and the appearance effect of the door body structure 100 is ensured, which is beneficial to improve the overall quality of the product.

[0125] Optionally, in the case that the magnetic member 150 is arranged on the door body assembly 120, based on that the first end 170 is movably connected with the support 110, the magnetic member 150 is arranged close to the second end 180, based on that the second end 180 is movably connected with the support 110, the magnetic member 150 is arranged close to the first end 170, thereby ensuring that the door body assembly 120 completely closes the opening 111.

[0126] Optionally, one of the magnetic member 150 and the cooperating member 160 is a magnet, and the other is a magnetic sheet.

[0127] Optionally, one of the magnetic member 150 and the cooperating member 160 is a magnet, and the other is a metal member.

[0128] In a specific embodiment, a water box glass door is arranged on the control panel support (the support 110), the water box glass is fixed on the water box glass plastic support, and the water box glass door is composed of the water box glass and the water box glass plastic support. The water box glass door is connected to the control panel support through a hinged structure. The water box glass plastic support is provided with an axle hole. The buffer (the buffer assembly 210) is fixed on the control panel support, and the buffer (the first buffer member 130) and the water box glass plastic support are connected through a connecting rod (the connecting member 122), one end of the connecting rod (the second connecting shaft 124) is installed in the axle hole of the water box glass plastic support, and the other end of the connecting rod (the first connecting shaft 123) is installed in the axle hole of the buffer (the first buffer member 130).

[0129] When the damper (first buffer 130) moves upward, the resistance is small or nonexistent; when it moves downward, the resistance increases significantly. During the opening of the water tank glass door (door assembly 120), the shaft at the other end of the connecting rod (first connecting shaft 123) begins to move upward. The water tank glass door experiences little resistance; when it reaches… Figure 1 At the indicated position, the shaft at the other end of the connecting rod (first connecting shaft 123) rotates downwards, and the water tank glass door (door assembly 120) is resisted by the damper (buffer assembly 210), slowly opening to the end point. At the end point, since the direction of the damper's resistance is vertical, and the water tank glass door is mainly subjected to the direction of gravity, the damper (buffer assembly 210) can provide sufficient resistance for the water tank glass door (door assembly 120), allowing the water tank glass door to descend slowly. During the closing process of the water tank glass door, the buffer (first buffer 130) begins to move upwards, and the resistance experienced by the water tank glass door is small. When the water tank glass door moves to... Figure 1 When the position is shown, the shaft (first connecting shaft 123) at the other end of the linkage begins to move downward, preventing the water box glass door (door assembly 120) from closing, thus achieving a slow closing effect.

[0130] Through the special design of the damper (buffer assembly 210) and connecting rod, the water tank glass door (door assembly 120) achieves both slow opening and slow closing functions during opening and closing. During the opening process, the water tank glass door can open rapidly in the initial stage (first position) and the middle stage (third position). In the final stage (second position), the damper counteracts gravity, causing the water tank glass door to fall slowly, avoiding vibration and noise caused by impact. Similarly, during the closing process, the water tank glass door (door assembly 120) can close rapidly in the initial stage (second position) and the middle stage (third position), while in the final stage (first position), the damper counteracts magnetic force, causing the water tank glass door to close slowly, again avoiding vibration and noise caused by impact.

[0131] According to a second aspect of the present invention, a cooking appliance is provided, including a door structure 100 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the door structure 100, which will not be repeated here.

[0132] Alternatively, cooking appliances include ovens, air fryers, microwave ovens, steam ovens, or microwave-steam-grill combos.

[0133] The door body structure 100 comprises a support 110, a door body assembly 120 and a buffer assembly 210. Specifically, along the height direction of the support 110, the door body assembly 120 comprises a first end 170 and a second end 180. Optionally, the first end 170 is a bottom end, and the second end 180 is a top end. The first end 170 is movably connected to the support 110, that is, the bottom end is movably connected to the support 110. Optionally, the door body assembly 120 is a down-opening type door opening and closing device. Alternatively, the second end 180 is movably connected to the support 110, that is, the top end is movably connected to the support 110. Optionally, the door body assembly 120 is an up-opening type door opening and closing device.

[0134] The buffer assembly 210 is arranged on the support 110, and the buffer assembly 210 is connected to the door body assembly 120. During the movement of the door body assembly 120 relative to the support 110 to open or close the opening 111, the door body assembly 120 can drive at least part of the buffer assembly 210 to move. It can be understood that the movement of at least part of the buffer assembly 210 can generate a buffer force.

[0135] The following is an example of a down-opening type door opening and closing device, that is, the bottom end of the door body assembly 120 is movably connected to the support 110. Specifically, during the movement of the door body assembly 120 relative to the support 110 to open the opening 111, that is, during the movement of the door body assembly 120 to the opening position, at least part of the buffer assembly 210 can be driven to move to generate a buffer force. The buffer force generated by the buffer assembly 210 can overcome the gravity acting on the door body assembly 120, thereby providing a certain resistance to the door body assembly 120 during the opening of the opening 111, so that the door body assembly 120 is slowly opened, avoiding the impact noise generated by the rapid descent of the door body assembly 120 under the action of gravity and the impact with the support 110.

[0136] In addition, during the movement of the door body assembly 120 relative to the support 110 to close the opening 111, that is, during the movement of the door body assembly 120 to the closing position, at least part of the buffer assembly 210 can be driven to move to generate a buffer force. The buffer force generated by the buffer assembly 210 can hinder the movement of the door body assembly 120 to the closing position, so that the door body assembly 120 is slowly closed, avoiding the impact noise generated by the impact of the door body assembly 120 on the support 110 at a relatively large speed.

[0137] By arranging the buffer assembly 210, the slow opening and closing function of the door body assembly 120 can be achieved, and the vibration and noise generated during the opening and closing of the door body assembly 120 can be significantly improved, which is beneficial to improve the opening and closing experience of the user on the door body structure 100.

[0138] As shown in FIG. 1, Figure 8 In some embodiments, the support 110 further comprises a containing cavity 112, the containing cavity 112 is in communication with the opening 111, and the cooking appliance further comprises a liquid storage box, the liquid storage box is arranged in the containing cavity 112 in a removable manner.

[0139] In this embodiment, the bracket 110 is further provided with a receiving cavity 112, and specifically, the receiving cavity 112 is in communication with the opening 111, and the liquid storage box is removably arranged in the receiving cavity 112.

[0140] Specifically, when the liquid storage box needs to be taken out, the door body assembly 120 moves to the open position, so that the opening 111 is opened, and the door body assembly 120 drives at least part of the buffer assembly 210 to generate a buffer force, and the generated buffer force can overcome the gravity acting on the door body assembly 120, thereby providing a certain resistance for the door body assembly 120 in the process of opening the opening 111, so that the door body assembly 120 is slowly opened, and impact noise is avoided due to the rapid descent of the door body assembly 120 under the action of gravity and the impact with the bracket 110.
