The door body assembly provided by the utility model comprises an installation structure, a pull rod structure, a door body and a damping structure. The damping structure is arranged on the mounting structure, the head of the pull rod structure is connected with the door body, and the tail of the pull rod structure is provided with a folding edge structure. In the closing process of the door body, the edge folding structure is abutted to the damping structure, and a certain buffering effect is achieved through the damping structure, so that collision between the damping structure and the appliance body of the cooking appliance is avoided.

In particular, the utility model is provided with the edge folding structure directly at the tail part of the pull rod structure, and the damping structure is abutted through the edge folding structure. Therefore, on one hand, the manufacturing difficulty of the pull rod structure can be effectively reduced, and the pull rod structure is convenient to process and manufacture; on the other hand, the contact area of the damping structure can be increased, and the damping structure is prevented from being separated from the folding edge structure.

Specifically, in the case where the door body is in the open state, the door body is in the horizontal state; at this time, the folding edge structure is separated from the damping structure. In the process that the door body is switched from the opening state to the closing state, the edge folding structure moves towards the damping structure under the driving of the pull rod structure and is abutted to the damping structure. Like this, the damping structure can play certain cushioning effect to the door body, and then guarantees that the door body slowly closes. Moreover, the contact area of the edge folding structure and the damping structure can be ensured through the arrangement of the edge folding structure, and the risk of separation of the damping structure is further reduced.

In some possible designs, the damping structure includes opposite connection ends and abutting ends, the damping structure is obliquely arranged on the mounting structure, and the abutting ends are lower than the connection ends; wherein, the link is connected with mounting structure, and the butt end is used for butt hem structure.

In addition, the abutting end is arranged lower than the connecting end, so that the damping structure is in an inclined state (namely, the central line of the damping structure is arranged obliquely compared with the horizontal plane). Particularly, the abutting end of the damping structure is a stressed end in contact with the edge folding structure, the position of the damping structure is optimized, the damping structure is obliquely arranged, the stressed abutting end of the damping structure is relatively downward, and the force applied to the pull rod structure by the damping structure faces the bottom of the door body assembly, so that the risk of separation of the pull rod structure from the mounting structure is reduced, and the opening and closing stability of the door body is ensured.

In some possible designs, the hemming structure comprises an abutment face for detachably abutting the damping structure; under the condition that the door body is in a closed state, a first included angle formed between the central line of the damping structure and the abutting surface is smaller than 90 degrees, and an opening of the first included angle faces the bottom of the door body assembly.

In this design, the hemming structure includes an abutment surface for detachably abutting the damping structure. Wherein, under the condition that the door body is in the closed condition, the central line of damping structure sets up in the slope of horizontal plane relatively to be formed with first contained angle between the central line of damping structure and the butt face, the opening of first contained angle is towards the bottom of door body group spare, and first contained angle is less than 90. Like this, through the optimization to first contained angle, guaranteed that damping structure applies the bottom towards door body group spare for the power of pull rod structure, and then reduced the risk that pull rod structure breaks away from mounting structure, guaranteed the stability that the door body opened and closed.

In some possible designs, the hem structure comprises: the first folding edge is connected to the tail part of the pull rod structure; the second folding edge is connected to the first folding edge, the second folding edge and the first folding edge are different in bending direction compared with the pull rod structure, and the abutting surface is located on the second folding edge.

The first folding edge is connected to the tail part of the pull rod structure and is bent towards a first direction compared with the pull rod structure; the second folded edge is connected to the first folded edge, and the second folded edge is bent towards a second direction compared with the pull rod structure. That is, the first and second folds are bent in opposite directions and abut the damping structure via the second fold. In particular, the abutment surface is located on the second fold and is adapted to detachably abut the damping structure.

In this way, the second folded edge has a larger area by the arrangement of the first folded edge and the second folded edge, particularly by arranging the first folded edge and the second folded edge to have opposite bending directions. And the second flanging is used for being abutted to the damping structure, so that the damping structure is ensured to be stably abutted to the second flanging, and the situation that the damping structure is separated from the second flanging is avoided.

Specifically, the first folded edge may be bent toward the left side compared to the pull rod structure, and the second folded edge may be bent toward the right side compared to the pull rod structure; the first folded edge may be bent toward the right side compared to the pull rod structure, and the second folded edge may be bent toward the left side compared to the pull rod structure.

In some possible designs, the door body assembly further includes: the roller is arranged on the mounting structure; wherein, the middle part of the pull rod structure is provided with a bending part, and the pull rod structure moves towards the roller and is contacted with the roller in the process of closing the door body.

Furthermore, a bending part is arranged in the middle of the pull rod structure, and the head part and the tail part of the pull rod structure are positioned on two sides of the bending part. Under the condition that the door body is in a closed state, the part of the pull rod structure between the bent part and the tail part is inclined upwards compared with the horizontal plane. That is, the tail portion of the pull rod structure is higher than the bent portion of the pull rod structure. At the moment, the edge folding structure at the tail part of the pull rod structure is obliquely arranged relative to the horizontal plane, the abutting surface of the edge folding structure is obliquely arranged relative to the horizontal plane, and the abutting surface of the edge folding structure is matched with the abutting end of the damping structure in position.

In addition, in the process of closing the door body, the pull rod structure moves towards one side of the roller and is in contact with the roller to press the roller. At the moment, the roller can be compressed through the pull rod structure, so that the pull rod structure is prevented from being separated from the roller, and the door body is guaranteed to be smoothly closed.

In some possible designs, the door body assembly further includes: and the elastic piece is removably connected to the tail part of the pull rod structure and the mounting structure and is used for resetting the pull rod structure.

In this design, the door body assembly further includes an elastic member. Wherein, the elastic component can remove the afterbody that is connected with the pull rod knot and mounting structure to be used for realizing pull rod structure's resetting.

Specifically, in the process that the door body is switched from the closed state to the open state, the elastic piece is stretched, and the elasticity of the elastic piece can also improve the strength of opening the door, so that the hand feeling of a user when opening the door body is improved. In the process that the door body is switched from the opening state to the closing state, the elastic piece gradually restores to the original state, and the elasticity of the elastic piece can also reduce the door closing strength, so that a user can conveniently close the door body.

Thus, the opening direction of the card interface is optimized, the first assembling surface is obliquely arranged compared with the vertical surface when the door body is in the vertical state, and a second included angle formed between the first assembling surface and the vertical surface is larger than 0 degree and smaller than or equal to 10 degrees. Under this state, can guarantee that the pivot of door body is stable in the inside of joint interface to guarantee that first assembly face can effectively carry on spacingly to the intraoral pivot of joint, and then reduced the pivot and followed the intraoral possibility that drops of joint.

In some possible designs, the head of the pull rod structure is provided with a clamping portion, and the clamping interface is arranged on the clamping portion.

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.

Door body assemblies and cooking appliances provided according to some embodiments of the present invention are described below with reference to fig. 1 to 9.

As shown in fig. 1 and 2, a first embodiment of the present invention provides a door body assembly including a mounting structure 102, a pull rod structure 104, a door body 108, and a damping structure 110.

As shown in fig. 1 and 2, the damping structure 110 is disposed on the mounting structure 102, the head portion 142 of the pull rod structure 104 is connected to the door body 108, and the tail portion 144 of the pull rod structure 104 is provided with the folding structure 106. In the closing process of the door body 108, the edge folding structure 106 abuts against the damping structure 110, and a certain buffering effect is achieved through the damping structure 110, so that collision between the damping structure 110 and the appliance body of the cooking appliance is avoided.

In particular, as shown in fig. 4, 5 and 6, the present invention provides the hem structure 106 directly at the tail portion 144 of the drawbar structure 104 and abuts the damping structure 110 through the hem structure 106. Therefore, on one hand, the manufacturing difficulty of the pull rod structure 104 can be effectively reduced, and the pull rod structure 104 is convenient to process and manufacture; on the other hand, the contact area of the damping structure 110 can be increased, and the damping structure 110 is prevented from being separated from the folding structure 106.

Specifically, as shown in fig. 1 and 2, in the case where the door body 108 is in the open state, the door body 108 is in the horizontal state; the hem structure 106 is now separated from the damping structure 110. In the process of switching the door body 108 from the open state to the closed state, the hem structure 106 is driven by the pull rod structure 104 to move toward the damping structure 110 and abut against the damping structure 110. In this way, the damping structure 110 can play a certain buffering role on the door body 108, thereby ensuring that the door body 108 is slowly closed. Moreover, by arranging the folding edge structure 106, the contact area between the folding edge structure 106 and the damping structure 110 can be ensured, and the risk of separation of the damping structure 110 is reduced.

A second embodiment of the present invention provides a door assembly, further comprising, in addition to the first embodiment:

as shown in fig. 3, the damping structure 110 includes opposing connection ends 112 and abutment ends 114. Wherein the connecting end 112 is connected with the mounting structure 102 to ensure the stable mounting of the whole damping structure 110, and the abutting end 114 is used for abutting against the folding edge structure 106, thereby realizing the slow closing of the door body 108.

Furthermore, as shown in fig. 3, the abutting end 114 is disposed lower than the connecting end 112, so that the damping structure 110 is in an inclined state (i.e., the center line L1 of the damping structure 110 is disposed inclined with respect to the horizontal plane L2). In particular, the abutting end 114 of the damping structure 110 is the stressed end in contact with the hem structure 106.

According to the utility model, the position of the damping structure 110 is optimized, so that the damping structure 110 is obliquely arranged, and the stressed abutting end 114 of the damping structure 110 is relatively downward, so that the force applied to the pull rod structure 104 by the damping structure 110 faces the bottom of the door body assembly, the risk of the pull rod structure 104 separating from the mounting structure 102 is further reduced, and the stability of opening and closing of the door body 108 is ensured.

In addition, the door body assembly proposed in this embodiment has all the benefits of the door body assembly of the first embodiment, and directly abuts against the damping structure 110 through the folded edge structure 106 of the tail portion 144 of the pull rod structure 104, so as to reduce the risk of the pull rod structure 104 separating from the mounting structure 102, and simplify the overall structure of the door body assembly, and ensure that the door body 108 is smoothly opened and closed, which is not discussed in detail herein.

A third embodiment of the present invention provides a door assembly, further comprising:

as shown in fig. 3, the hem structure 106 includes an abutment surface 116 for abutting the damping structure 110. When the door body 108 is in the closed state, the center line L1 of the damping structure 110 is inclined with respect to the horizontal plane, a first included angle α 1 is formed between the center line L1 of the damping structure 110 and the abutting surface 116, an opening of the first included angle α 1 faces the bottom of the door body assembly, and the first included angle α 1 is smaller than 90 °.

Thus, as shown in fig. 3, by optimizing the first included angle α 1, it is ensured that the force applied to the pull rod structure 104 by the damping structure 110 is directed toward the bottom of the door body assembly, so as to reduce the risk of the pull rod structure 104 being separated from the mounting structure 102, and ensure the stability of opening and closing of the door body 108.

In this embodiment, further, as shown in fig. 3, the hem structure 106 includes an abutment face 116, the abutment face 116 for abutting the damping structure 110. When the door body 108 is in the closed state, the center line of the damping structure 110 is inclined with respect to the horizontal plane, a first included angle α 1 is formed between the center line L1 of the damping structure 110 and the abutting surface 116, an opening of the first included angle α 1 faces the bottom of the door body assembly, and the first included angle α 1 is smaller than 90 °.

In this way, through the optimization of the first included angle α 1, it is ensured that the force applied to the pull rod structure 104 by the damping structure 110 is directed toward the bottom of the door body assembly, so that the risk of the pull rod structure 104 breaking away from the mounting structure 102 is reduced, and the opening and closing stability of the door body 108 is ensured.

Specifically, the first included angle α 1 formed between the central line L1 of the damping structure 110 and the abutment surface 116 may be 45 °, 50 °, 55 °, 60 °, 65 °, 70 °, 75 °, 80 °, 85 °, 90 °, etc., which will not be discussed in detail herein.

A fourth embodiment of the present invention provides a door assembly, further comprising, in addition to the first, second and third embodiments:

the door body assembly also includes rollers 126. Wherein the roller 126 is rotatably disposed on the mounting structure 102, and the pull rod structure 104 is in contact with the roller 126, so as to make the opening and closing of the door body 108 smoother.

In addition, a bent portion 118 is disposed in the middle of the pull rod structure 104, and the head portion 142 and the tail portion 144 of the pull rod structure 104 are disposed on two sides of the bent portion 118. With the door body in the closed position, the portion of the drawbar arrangement 104 between the bent portion 118 and the tail portion 144 is inclined upward compared to the horizontal. That is, the tail portion 144 of the drawbar structure 104 is disposed higher than the bent portion 118 of the drawbar structure 104. At this time, the hem structure 106 at the tail portion 144 of the drawbar structure 104 is disposed obliquely with respect to the horizontal plane, so that the abutting surface 116 of the hem structure 106 is disposed obliquely with respect to the horizontal plane, and the abutting surface 116 of the hem structure 106 is ensured to match the position of the abutting end 114 of the damper structure 110.

Further, during the closing of the door body 108, the draw bar structure 104 moves toward the side of the roller 126 and contacts the roller 126 to press the roller 126. At this time, the roller 126 can be pressed by the pull rod structure 104, so as to prevent the pull rod structure 104 from being separated from the roller 126, thereby ensuring that the door body 108 is smoothly closed.

A fifth embodiment of the present invention provides a door body assembly, further comprising, in addition to the first, second, third and fourth embodiments:

as shown in fig. 6 and 9, the hem structure 106 includes a first hem 120 and a second hem 122. Wherein the first flange 120 is connected to the tail portion 144 of the pull rod structure 104, and the first flange 120 is bent toward a first direction compared with the pull rod structure 104; the second folded edge 122 is connected to the first folded edge 120, and the second folded edge 122 is bent toward the second direction compared to the pull rod structure 104, and the abutting surface 116 is located on the second folded edge 122. That is, the first fold 120 and the second fold 122 are bent in opposite directions and abut the damping structure 110 via the second fold 122.

Thus, as shown in fig. 6 and 9, the present invention allows the second folded edge 122 to have a larger area by the arrangement of the first folded edge 120 and the second folded edge 122, and particularly, by arranging the first folded edge 120 and the second folded edge 122 to be bent in opposite directions. The second folded edge 122 is used for abutting against the damping structure 110, which also ensures that the damping structure 110 and the second folded edge 122 can be stably abutted against each other, and avoids the situation that the damping structure 110 is separated from the second folded edge 122.

Specifically, as shown in fig. 6 and 9, the first folded edge 120 may be folded toward the left side compared to the pull rod structure 104, and the second folded edge 122 may be folded toward the right side compared to the pull rod structure 104; alternatively, the first folded edge 120 is folded toward the right side compared to the pull rod structure 104, and the second folded edge 122 is folded toward the left side compared to the pull rod structure 104.

Specifically, the abutment surface 116 of the hem structure 106 is disposed on the second hem 122.

as shown in fig. 1 and 2, the door body assembly further includes an elastic member 124. Wherein the resilient member 124 is coupled to the tail portion 144 of the drawbar knot and the mounting structure 102 and is configured to effect a return of the drawbar structure 104.

Specifically, as shown in fig. 1 and 2, in the process of switching the door body 108 from the closed state to the open state, the elastic member 124 is stretched, and the elastic force of the elastic member 124 can also improve the strength of the door opening, thereby improving the hand feeling of the user when opening the door body 108. In the process of switching the door body 108 from the open state to the closed state, the elastic element 124 gradually recovers to its original state, and the elastic force of the elastic element 124 can also reduce the strength of the door, thereby facilitating the user to close the door body 108.

Specifically, the elastic member 124 may employ a spring.

A seventh embodiment of the present invention provides a door body assembly, further comprising, in addition to the first, second, third, fourth, fifth and sixth embodiments:
