Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and in particular to a door assembly for a cooking device and the cooking device itself. Background Technology

[0002] Microwave ovens, steam ovens, ovens and other common cooking appliances mostly have a door structure located on one side of the cooking appliance body. The opening and closing of the door is used to open or close the inner cavity set on the cooking appliance body.

[0003] Existing door structures typically include an outer glass panel, an inner glass panel, an upper support member, and a lower support member. The lower support member has a slot with an opening facing the first bracket. The lower end of the inner glass panel is inserted into the slot, while the upper end of the inner glass panel is fixedly connected to the first bracket to fix the inner glass panel in the height direction of the door.

[0004] However, in order to form a slot, the lower support must have a portion located on the side of the inner glass facing away from the outer glass, which makes the lower support thicker in the thickness direction of the door assembly. As a result, when the door assembly closes the inner cavity of the cooking device, the lower support will occupy a large portion of the device body's space in the thickness direction, thus reducing the actual usable space in the inner cavity at the position of the lower support. Utility Model Content

[0005] In view of the above problems, this application provides a door assembly for a cooking device and a cooking device, aiming to solve the technical problem that existing door assemblies will reduce the actual usable space inside the device body.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a door assembly for a cooking device, including a first door, a first support, two abutments, a water guide, and a second door. The first door has a front and a back side disposed opposite to each other, wherein the back side is adjacent to the cooking device. The first support is adhered to the back side of the first door and close to the upper end of the first door, extending along the width direction of the first door, and has a support surface on the side of the first support facing away from the first door. The two abutments are symmetrically adhered to the back side of the first door and opposite sides of the lower end of the first door along the width direction of the first door, wherein the surface of each abutment facing away from the first door is not higher than the support surface. The water guide is used to collect condensate on the surface of the door assembly adjacent to the cooking device, and the water guide is connected between the two abutments. The water guide has a limiting groove with an opening on the side facing the first support. The surface of the second door facing the support surface is adhered to the support surface, and the end of the second door near the water guide is inserted into the limiting groove and adhered to the groove wall.

[0008] The door assembly for a cooking device provided by this utility model involves attaching two abutments to opposite sides of the back of a first door assembly near the lower end of the assembly. This positions a water guide between the two abutments on the back of the first door assembly, near the lower end, and the water guide is fixed relative to the first door assembly. A first bracket is attached to the back of the first door assembly near its upper end, with the water guide and the first bracket spaced apart along the height of the first door assembly. A limiting groove with an opening facing the first bracket and a supporting surface on the side of the first bracket facing away from the first door assembly are provided on the water guide. This allows the end of the second door assembly near the water guide to be inserted into the limiting groove and bonded to the groove wall. The surface of the second door assembly facing the supporting surface is also bonded to the supporting surface, thus achieving relative fixation between the second and first doors. Furthermore, by setting the side of the abutment facing away from the first door to be no higher than the support surface, the distance between the side of the abutment facing away from the first door and the back of the first door is smaller than the distance between the second door and the first door. The second door can completely cover the abutment and the first bracket, thereby reducing the thickness of the abutment in the thickness direction of the equipment body, reducing the space occupied by the abutment in the thickness direction of the equipment body, and increasing the actual usable space of the cooking cavity.

[0009] In some embodiments, the groove wall surface of the limiting groove near the first door body, the supporting surface, and the surface of the blocking member on the side away from the first door body are located on the same plane.

[0010] In this way, the blocking component can provide support for the second door, increase the support area for the second door, and improve the stability of the second door after it is relatively fixed to the first door.

[0011] In some embodiments, the water guide has connecting portions extending toward one side of the first door body at both ends, and each of the abutting members has an abutting portion extending toward one side of the water guide.

[0012] When the water guide is installed between the two abutments, the connecting part is located above the abutment, and the connecting part is detachably connected to the abutment.

[0013] In this way, on the one hand, the blocking part can provide support and limit for the connecting part and the water guide, so that the water guide can better support the second door after the connecting part and the blocking part are connected; on the other hand, it can also make it easier to install and fix the second door. For example, before the connecting part and the blocking part are connected, the second door can be inserted into and glued to the limiting groove of the water guide. Then, the second door and the water guide are treated as a whole, and the relative fixation of the second door and the blocking part is achieved by connecting the connecting part and the blocking part.

[0014] In some embodiments, the door assembly further includes a threaded connector, the abutment having a through hole extending along the height direction of the first door, the connecting portion having a threaded hole that matches the threaded connector, and the threaded connector passing through the through hole and being threadedly connected to the threaded hole.

[0015] In this way, the threaded connector passes through the through hole from bottom to top and is threaded into the threaded hole, so that the head of the threaded connector can be hidden below the stop part. The head of the threaded connector is closer to the lower edge of the door assembly, avoiding the head of the threaded connector occupying the space in the middle area of ​​the cooking cavity.

[0016] In some embodiments, the water guide further includes a water guide groove disposed on the side of the limiting groove opposite to the first door body and communicating with the surface of the second door body.

[0017] In this way, the water guide can collect the condensate dripping from the surface of the second door.

[0018] In some embodiments, the abutment is a plastic component.

[0019] By using plastic components for the stoppers, the weight of the stoppers can be reduced, which also lowers the cost of the door assembly.

[0020] In some embodiments, the door assembly further includes a second bracket, a third bracket, and a third door body. Along the width direction of the first door body, the second bracket and the third bracket are symmetrically arranged on the back side of the first door body and are bonded to the back side. The two abutments are respectively fixed below the second bracket and the third bracket.

[0021] Both the second and third supports have stepped surfaces on the side facing the other. The third door is located between the first and second door bodies and is fixed to the stepped surfaces of the second and third supports.

[0022] In this way, the stepped surfaces on the second and third supports can be fixedly connected to the third door body on both sides along the width direction of the first door body, thereby forming a support for the third door body and allowing a gap between the third door body and the first door body, which can improve the heat insulation effect of the door body assembly.

[0023] In some embodiments, each of the abutments has a first limiting structure extending toward one side of the first bracket on the side facing the first bracket; the first bracket has a second limiting structure extending toward the abutment on the side facing the abutment;

[0024] When the third door is disposed on the step surface, along the thickness direction of the door assembly, the end of the third door near the lower end of the door assembly is limited between the step surface and the first limiting structure, and the end of the third door near the upper end of the door assembly is limited between the step surface and the second limiting structure.

[0025] In this way, the first limiting structure, together with the step surface, can limit the relative two side surfaces of the third door body near the lower end of the door body assembly, and the second limiting structure, together with the step surface, can limit the relative two side surfaces of the third door body near the upper end of the door body assembly, thereby realizing the limiting and fixing of the third door body at both ends in the height direction of the door body assembly, making the installation of the third door body more stable.

[0026] In some embodiments, the door assembly further includes a seal located below the first bracket and wrapped around the outer periphery of the upper end of the third door, and the second limiting structure is located on the side of the seal opposite to the first door and abuts against the seal.

[0027] In this way, the seal can reduce the shaking of the end of the third door near the upper part of the door assembly, improve the sealing between the end of the third door near the upper part of the door assembly and the first bracket, and prevent steam from entering the gap between the first door and the third door from the end of the third door near the upper part of the door assembly.

[0028] In some embodiments, the abutment has a first limiting surface on the side facing the first bracket, and the seal has a second limiting surface on the side facing the abutment. Along the height direction of the door assembly, the third door is limited between the first limiting surface and the second limiting surface.

[0029] In this way, the first limiting surface and the second limiting surface can limit the end faces of the third door body at both ends in the height direction of the door body assembly, thereby further improving the stability of the installation of the third door body under the joint limiting of the first limiting surface and the second limiting surface.

[0030] In some embodiments, the first limiting structure is a limiting boss, and the side of the limiting boss facing the step surface has a guide slope, so that the bottom end of the third door body is limited between the limiting boss and the step surface along the guide slope.

[0031] In this way, guided by the inclined plane, the end of the third door body near the lower end of the door body assembly can be inserted more easily into the gap between the first limiting structure and the step surface.

[0032] In some embodiments, the second limiting structure is an elastic limiting plate, and the elastic limiting plate has a guide portion that is inclined away from the step surface, so that the top end of the third door is limited between the step surface and the elastic limiting plate along the guide portion.

[0033] In this way, the elastic limiting plate can undergo elastic deformation to increase the opening size between the second limiting structure and the step surface, and under the guidance of the guide part, the end of the third door body near the upper end of the door body assembly can easily enter the gap between the second limiting structure and the step surface.

[0034] In some embodiments, there are at least two second limiting structures, arranged sequentially at intervals along the width direction of the first door body.

[0035] In this way, at least two second limiting structures can limit the third door at at least two points, thus improving the limiting effect on the third door.

[0036] A second aspect of this application provides a cooking device, including a device body and a door assembly provided in the first aspect above. The device body has an inner pot, and the front side of the device body has an opening communicating with the inner pot. The door assembly is movably disposed at the opening to open or close the opening.

[0037] The cooking device provided in this application embodiment has the same beneficial effects as the door assembly for cooking device provided in the above embodiment, and will not be repeated here.

[0038] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the door assembly for cooking equipment and the cooking equipment provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0058] This application provides a cooking device, including but not limited to microwave ovens, steam ovens, and ovens. Taking an oven as an example, the cooking device includes a main body and a door assembly. The main body has a cooking cavity with one open side, which is used to hold food to be cooked. The door assembly is movably disposed at the open side to close or open the cooking cavity. When the cooking cavity is open, it is convenient for the user to take out or put in food; when the cooking cavity is closed, it helps to improve the cooking effect. Since the door assembly is one of the core safety components of the oven, it must take into account sealing, heat preservation, durability, and ease of maintenance.

[0059] In this article, the lower end of the door assembly is rotatably connected to the device body so that the door assembly can open or close the opening of the cooking cavity. The orientation of each component in the door assembly is described with reference to the orientation of the door assembly in the closed state.

[0060] Please refer to Figure 1 and Figure 2 As shown, in order to facilitate understanding of the technical solution of this application, in this embodiment, the width direction of the door assembly 10 is the X direction, the height direction is the Y direction, and the thickness direction of the door assembly 10 is the Y direction.

[0061] The door assembly 10 for cooking provided in this application includes a first door 100, a first support 200, two stoppers 300, and a second door 500.

[0062] The first door 100 has a front and a back side disposed opposite to each other. The front and back sides of the first door 100 are two opposite surfaces of the first door 100 along the thickness direction of the door assembly 10. When the door assembly 10 closes the cooking cavity, the front side of the first door 100 can be the side of the first door 100 facing away from the cooking cavity, and the back side of the first door 100 can be the side of the first door 100 facing the cooking cavity. The first door 100 provides a mounting base for at least some other components in the door assembly 10, so that at least some other components can be directly or indirectly mounted on the first door 100.

[0063] The first bracket 200 is adhered to the back of the first door body 100 and near the upper end of the first door body 100, extending along the width direction of the first door body 100. The side of the first bracket 200 facing away from the first door body 100 has a support surface 201, and the surface of the second door body 500 facing the support surface 201 is adhered to the support surface 201. Figure 2 As shown, the upper and lower ends of the first door body 100 are two opposite positions along the height direction of the door body assembly 10, and the width direction of the first door body 100 is the same as the width direction of the door body assembly 10. By using adhesive to fix the first bracket 200 to the first door body 100, the first bracket 200 will not cause damage to the first door body 100 such as openings or grooves, avoiding stress concentration at openings or grooves, and giving the first door body 100 higher strength. The first bracket 200 extends along the width direction of the first door body 100. It can be that both ends of the first bracket 200 extend along the width direction of the first door body 100. The extended first bracket 200 can provide a larger installation area for the second door body 500 and more optional installation positions for the second limiting structure 220. Furthermore, the two ends of the extension direction of the first bracket 200 do not exceed the width of the first door body 100, so that the first bracket 200 can be completely hidden on the back of the first door body 100, avoiding interference with the opening or closing of the door assembly 10. After the support surface 201 on the first bracket 200 is bonded to the second door body 500, the top end of the second door body 500 can be fixed on the support surface 201.

[0064] like Figure 1 and Figure 2As shown, two abutment members 300 are symmetrically adhered to the back of the first door body 100 and to opposite sides near the lower end of the door assembly, along the width direction of the first door body 100. The adhesion of the two abutment members 300 to the first door body 100 prevents damage such as drilling or slotting during installation, avoiding stress concentration at such locations and thus increasing the strength of the first door body 100. The two abutment members 300 can be directly or indirectly connected to the bottom end of the second door body 500, allowing them to secure the lower end of the second door body 500.

[0065] It should be noted that when the door assembly 10 is in the closed state, the second door 500 is vertically positioned and will be subjected to a downward vertical force. Therefore, in order to support and fix the second door 500, the prior art provides slots with openings facing the first bracket 200 on the two abutment members 300, so that the bottom end of the second door 500 can be inserted into the two slots of the two abutment members 300, thereby supporting and fixing the lower end of the second door 500 through the slots. This design results in the slot formed by the abutment 300 being higher than the side surface of the second door 500 facing away from the first door 100 along the thickness direction of the first door 100. This makes the thickness of the abutment 300 in the thickness direction of the door assembly 10 larger. Consequently, when the door assembly 10 closes the cooking cavity, the abutment 300 occupies a larger space in the thickness direction of the device body, resulting in a reduction in the actual usable space of the inner cavity at the position of the corresponding lower support member. The size of the actual usable space of the inner cavity determines the volume of food that the inner cavity can hold. A reduction in the actual usable space of the inner cavity will lead to a reduction in the volume of food that the inner cavity can hold.

[0066] To address the aforementioned issues, this application provides an improved door assembly 10, which aims to reduce the actual usable space of the inner cavity occupied by the support members of the door assembly 10.

[0067] The door assembly 10 provided in the embodiments of this application will be further described below with reference to the accompanying drawings, based on the above embodiments.

[0068] Please continue to refer to Figure 1 and Figure 2 As shown, in this embodiment, the side surface of the blocking member 300 facing away from the first door 100 is not higher than the support surface 201, so that when the side surface of the second door 500 close to the first door 100 is in contact with the support surface 201, the second door 500 will not be interfered with by the blocking member 300. At the same time, the thickness of the blocking member 300 is reduced, thereby reducing the space of the device body in the thickness direction occupied by the position corresponding to the blocking member 300, and increasing the actual usable space of the cooking cavity.

[0069] And, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the door assembly 10 for the cooking device also includes a water guide 400, which is disposed between the two abutments 300 and connected to the two abutments 300 respectively (e.g., Figure 2 As shown in the diagram, the water guide 400 has a limiting groove 401 with an opening on one side facing the first bracket 200 (as shown in the diagram). Figure 5 As shown in the diagram, the end of the second door 500 near the water guide 400 is inserted into the limiting groove 401 and bonded to the wall of the limiting groove 401. The end of the second door 500 near the water guide 400 is the bottom end of the second door 500. By inserting the second door 500 into the limiting groove 401, the opposite side walls and bottom of the limiting groove 401 can limit the bottom end of the second door 500, and the limiting groove 401 also provides support for the second door 500. Bonding the second door 500 to the wall of the limiting groove 401 further improves the stability of the connection between the second door 500 and the water guide 400, and allows the second door 500 to be relatively fixed to the first door 100 through the water guide 400 and the first bracket 200. By fixing both ends of the water guide 400 to the two abutment members 300 and setting a limiting groove 401 on the water guide 400, on the one hand, regardless of whether the abutment member 300 is provided with a slot, the limiting groove 401 can support and fix the bottom end of the second door 500. On the other hand, the water guide 400 can selectively be spaced apart from or in contact with the first door 100. When the water guide 400 is spaced apart from the first door 100, that is, when the water guide 400 is not in direct contact with the first door 100, the thickness of the water guide 400 in the thickness direction of the first door 100 can be reduced to a certain extent.

[0070] The water guide 400 is mainly used to guide the condensate on the second door 500. Specifically, when the door assembly 10 closes the cooking cavity and cooking begins, the temperature of the side of the second door 500 facing away from the first door 100 rises. When the door assembly 10 opens the cooking cavity, the side of the second door 500 facing away from the first door 100 comes into direct contact with the cooler ambient air, causing condensate to form on this side. Under gravity, the condensate drips towards the bottom of the second door 500. After flowing through the water guide 400, the condensate is guided to a location that facilitates drainage or collection. For example, the water guide 400 can guide the condensate into the water channel 410 on the water guide 400 (e.g., Figure 4 (as shown in the image).

[0071] like Figures 4 to 6As shown, the groove wall surface of the limiting groove 401 near the first door body 100, the supporting surface 201, and the surface of the abutment 300 away from the first door body 100 are all on the same plane. This allows this plane to form the mounting surface of the second door body 500. When the second door body 500 is fixed to the supporting surface 201, it can also simultaneously fit against the groove wall surface of the limiting groove 401 near the first door body 100 and the groove wall surface of the abutment 300 away from the first door body 100. This also facilitates the simultaneous bonding and fixing of the second door body 500 to the limiting groove 401, the supporting surface 201, and the abutment 300, thereby improving the relative stability of the fixed relationship between the second door body 500 and the first door body 100.

[0072] like Figure 4 and Figure 5 As shown, the water guide 400 has connecting portions 420 extending toward the first door body 100 at both ends, and each abutment 300 has an abutment portion 310 extending toward the water guide 400. When the water guide 400 is installed between two abutments 300, the connecting portion 420 is located above the abutment portion 310, and the connecting portion 420 and the abutment portion 310 are detachably connected.

[0073] By providing the connecting part 420 and the abutting part 310, when the door assembly 10 is in the closed position, the connecting part 420 is located above the abutting part 310. The connecting part 420 is abutted against the abutting part 310 by the downward gravity of the second door 500 and the water guide 400, thus enabling the abutting part 310 to provide support and fixation for the connecting part 420. Simultaneously, by providing the connecting part 420 and the abutting part 310, the connection or disassembly between the water guide 400 and the abutting part 300 can be achieved more conveniently. For example, before connecting the connecting part 420 and the abutting part 310, the second door 500 can be pre-inserted and glued into the limiting groove 401 of the water guide 400. Then, the second door 500 and the water guide 400 can be treated as a whole, and the relative fixation of the second door 500 and the abutting part 300 can be achieved by connecting the connecting part 420 and the abutting part 310.

[0074] like Figure 4 and Figure 5 As shown, the door assembly 10 also includes a threaded connector. The abutment portion 310 has a through hole 311 extending along the height direction of the first door 100. The connecting portion 420 has a threaded hole 421 that matches the threaded connector. The threaded connector passes through the through hole 311 and is threadedly connected to the threaded hole 421.

[0075] By using threaded connectors such as bolts and cooperating with through holes 311 and threaded holes 421, the connection or disassembly between the water guide 400 and the stop 300 can be quickly achieved by rotating the threaded connectors. The threaded hole 421 is located above the through hole 311, so that the threaded connector passes through the through hole 311 from bottom to top and is threaded into the threaded hole 421. This allows the head of the threaded connector, such as the bolt head, to be hidden below the stop 310, and the head of the threaded connector to be closer to the lower edge of the door assembly 10, avoiding the head of the threaded connector occupying space in the middle area of ​​the cooking cavity.

[0076] Hot condensate drips down from the door assembly 10. To reduce the risk of burns to the operator of the cooking equipment from the hot condensate dripping down during the opening of the door assembly 10, such as... Figure 4 and Figure 5 As shown, the water guide 400 also has a water guide groove 410, which is disposed on the side of the limiting groove 401 opposite to the first door body 100. After the door body assembly 10 is opened, condensate can drip downwards and enter the water guide groove 410, where it is collected.

[0077] The opening of the water guide trough 410 can be set on the wall of the water guide 400 on the side away from the first door 100. During the process of the door assembly 10 from closing to opening, the second door 500 is gradually adjusted from vertical to tilted. At this time, the opening of the water guide trough 410 is also tilted upward, so that the condensate can be collected and temporarily stored in the water guide trough 410.

[0078] The abutment 300 can be made of plastic to reduce its weight, thereby reducing the weight of the entire door assembly 10. Plastic is generally less expensive than metal, thus effectively reducing the production cost of the door assembly 10. Of course, in other embodiments, the abutment 300 can be made of metal; this embodiment does not specifically limit its use.

[0079] like Figure 1 , Figure 2 and Figure 5 As shown, the door assembly 10 also includes a second bracket 600, a third bracket 700, and a third door 800. Along the width direction of the first door 100, the second bracket 600 and the third bracket 700 are symmetrically arranged on the back side of the first door 100 and are bonded to the back side. Two abutments 300 are respectively fixed below the second bracket 600 and the third bracket 700. One of the second bracket 600 and the third bracket 700 has a stepped surface 610 on the side facing the other. The third door 800 is located between the first door 100 and the second door 500 and is fixed on the stepped surface 610 of the second bracket 600 and the third bracket 700.

[0080] The second bracket 600 and the third bracket 700 are bonded to the back of the first door body 100, preventing damage such as openings or slots, thus avoiding stress concentration at these locations and increasing the strength of the first door body 100. Along the thickness direction of the first door body 100, the stepped surfaces 610 on the second bracket 600 and the third bracket 700 are lower than the groove wall of the slot. The stepped surfaces 610 provide a mounting base for the third door body 800, allowing it to contact and be fixed with the two stepped surfaces 610, increasing the stability of the third door body 800 after connection. This design is simple and easy to implement. It also allows the third door body 800 to be positioned between the first door body 100 and the second door body 500. The third door body 800 divides the gap between the first door body 100 and the second door body 500 into two heat-insulating chambers, thereby reducing the heat dissipation efficiency between the second door body 500 and the first door body 100 and improving the heat insulation effect of the door assembly 10.

[0081] In some embodiments, the stepped surface 610 is parallel to the back surface of the first door body 100 so that the third door body 800 can be parallel to the first door body 100. This ensures that the distance between any position of the first door body 100 and the third door body 800 remains equal, thereby enabling the heat insulation cavity between the third door body 800 and the first door body 100 to achieve a uniform heat insulation effect.

[0082] Two abutment members 300 are respectively fixed below the second bracket 600 and the third bracket 700. The abutment member 300 fixed below the second bracket 600 can be pre-connected to the second bracket 600 to form the second bracket 600 assembly. Then, by bonding the second bracket 600 assembly to the back of the first door body 100, the second bracket 600 and its corresponding abutment member 300 can be quickly fixed to the first door body 100. Similarly, the abutment member 300 fixed below the third bracket 700 can be pre-connected to the third bracket 700 to form the third bracket 700 assembly. Then, by bonding the third bracket 700 assembly to the back of the first door body 100, the third bracket 700 and its corresponding abutment member 300 can be quickly fixed to the first door body 100.

[0083] like Figure 4 and Figure 5 As shown, each stopper 300 has a first limiting structure 320 extending toward the first support 200 on the side facing the first support 200. When the third door 800 is disposed on the step surface 610, along the thickness direction of the door assembly 10, the end of the third door 800 near the lower end of the door assembly is limited between the step surface 610 and the first limiting structure 320.

[0084] It is understood that the first limiting structure 320 and the support surface 201 are in contact with the relative surfaces of the bottom end of the third door body 800, so as to restrict the movement of the bottom end of the third door body 800 in the thickness direction of the third door body 800, reduce the probability of the bottom end of the third door body 800 detaching from the support surface 201, and increase the stability of the third door body 800 in the door assembly 10.

[0085] like Figure 6 As shown, the first bracket 200 has a second limiting structure 220 extending toward the blocking member 300 on the side facing the blocking member 300. When the third door body 800 is disposed on the step surface 610, the end of the third door body 800 near the upper end of the door body assembly 10 is limited between the step surface 610 and the second limiting structure 220.

[0086] The second limiting structure 220 and the support surface 201 respectively contact the relative surfaces of the top end of the third door body 800 to restrict the movement of the top end of the third door body 800 in the thickness direction of the third door body 800, reduce the probability of the top end of the third door body 800 detaching from the support surface 201, and increase the stability of the third door body 800 in the door assembly 10.

[0087] like Figure 6 As shown, the door assembly 10 also includes a seal 900, which is located below the first bracket 200 and wraps around the outer periphery of the upper end of the third door 800. The second limiting structure 220 is located on the side of the seal 900 away from the first door 100 and abuts against the seal 900.

[0088] The sealing element 900 is sealed to the upper end of the third door body 800. At the same time, when the second limiting structure 220 is an elastic limiting plate, the sealing element 900 can play a certain buffering role. When the second limiting structure 220 abuts against the sealing element 900, part of the abutting force provided by the second limiting structure 220 will be absorbed by the sealing element 900, thereby preventing the impact force when the second limiting structure 220 directly abuts against the third door body 800 from being too large and causing damage to the third door body 800. The sealing element 900 can reduce the shaking of the end of the third door body 800 near the upper end of the door body assembly 10, improve the sealing between the end of the third door body 800 near the upper end of the door body assembly 10 and the first bracket 200, and prevent steam from entering the gap between the first door body 100 and the third door body 800 from the end of the third door body 800 near the upper end of the door body assembly.

[0089] like Figure 4 As shown, the side of the abutment 300 facing the first bracket 200 has a first limiting surface 330, such as... Figure 6As shown, the sealing member 900 has a second limiting surface 910 on the side facing the blocking member 300, and the third door 800 is limited between the first limiting surface 330 and the second limiting surface 910 along the height direction of the door assembly 10.

[0090] The first limiting surface 330 on the abutment 300 can restrict the movement of the third door 800 towards the side opposite to the first bracket 200, that is, the first limiting surface 330 can restrict the downward movement of the third door 800. The second limiting surface 910 on the seal 900 can restrict the movement of the third door 800 towards the side opposite to the abutment 300, that is, the second limiting surface 910 can restrict the downward movement of the third door 800. Under the combined action of the first limiting surface 330 and the second limiting surface 910, the third door 800 can be limited at both ends in the height direction of the door assembly 10, avoiding the movement of the third door 800 in the height direction and improving the stability of the relative position of the third door 800 and the first door 100. At the same time, it can also reduce the probability of the third door 800 detaching from the adhesive position of the step surface 610.

[0091] For example Figure 4 and Figure 5 As shown, the first limiting structure 320 in this embodiment is a limiting boss. The side of the limiting boss facing the step surface 610 has a guide slope 321 so that the bottom end of the third door body 800 is limited between the limiting boss and the step surface 610 along the guide slope 321.

[0092] like Figure 2 and Figure 5 As shown, the second limiting structure 220 is an elastic limiting plate, and the elastic limiting plate has a guide portion 221 that is inclined to the side away from the step surface 610, so that the top end of the third door body 800 is limited between the step surface 610 and the elastic limiting plate along the guide portion 221.

[0093] A first groove is formed between the limiting boss and the step surface 610. The side of the limiting boss facing the step surface 610 and the step surface 610 respectively form the opposite groove walls of the first groove, so that the bottom end of the third door 800 can be placed between the first limiting structure 320 and the step surface 610 by inserting it into the first groove, making the installation of the bottom end of the third door 800 more convenient.

[0094] The guide ramp 321 is used to guide the bottom end of the third door 800 so that the bottom end of the third door 800 can be inserted into the first groove more easily. For example, the opening of the first groove is flared to facilitate the insertion of the bottom end of the third door 800.

[0095] like Figure 6As shown, a second groove is formed between the elastic limiting plate and the stepped surface 610. The side of the elastic limiting plate facing the stepped surface 610 and the stepped surface 610 respectively constitute the opposite groove walls of the second groove. Furthermore, the elastic limiting plate is elastic and can undergo elastic deformation under external force. For example, by manually moving the free end of the elastic limiting plate away from the stepped surface 610, the opening size of the second groove can be increased, and under the guidance of the guide part 221, the end of the third door 800 near the upper end of the door assembly 10 can easily enter the second groove. After the third door 800 is inserted into the second groove, by releasing the movement of the elastic limiting plate, the free end of the elastic limiting plate can abut against the third door 800 under the action of elastic force.

[0096] like Figure 2 As shown, there are at least two second limiting structures 220, arranged sequentially at intervals along the width direction of the first door body 100.

[0097] The width direction of the first door 100 is the same as that of the third door 800. At least two second limiting structures 220 can respectively cooperate with the step surface 610 at opposite positions to limit different positions of the third door 800 in the width direction, thereby improving the limiting effect of the third door 800.
