Description

Technical Field

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

[0002] The doors of cooking appliances such as microwave-steam-grill combos typically adopt a multi-layer composite structure design to meet the requirements of sealing, heat insulation and safety. To facilitate users in opening and closing the door, handles are usually also provided on the door.

[0003] In related technologies, the door body includes an outer glass, a middle glass, an inner glass, a left bracket, a right bracket, an upper bracket, and a handle. During assembly, the handle is first fixed to the outer glass with screws. Then, the upper bracket is fixed to the side of the outer glass away from the handle with screws, covering the screws connecting the handle and the outer glass. Next, the left and right brackets are installed on the outer glass, located on both sides of the upper bracket and connected to the upper bracket with screws. Then, the middle glass and the inner glass are installed on the left and right brackets. Finally, left and right support blocks are fixed to the ends of the left and right brackets away from the upper bracket to fix and limit the middle and inner glass, completing the installation of the door body.

[0004] However, in the relevant technologies, when it is necessary to replace or repair the handle, the left and right support blocks, inner glass, middle glass, left and right brackets and upper bracket must all be removed in sequence before the handle can be removed. This results in the inconvenience of replacing or repairing the handle and the high maintenance cost. Utility Model Content

[0005] In view of the above problems, this application provides a door assembly and cooking equipment to solve the problem of inconvenience in removing or replacing handles, reduce the difficulty of disassembling handles, and thus reduce maintenance costs.

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

[0007] The first aspect of this application provides a door assembly, the bottom end of which is rotatably connected to a cooking device, comprising:

[0008] The first door body has mounting holes;

[0009] The handle has a connecting part, which passes through the mounting hole and is detachably connected to the first door body;

[0010] Two first brackets are disposed on the side of the first door body away from the handle. Along the first direction, the two first brackets are symmetrically distributed on both sides of the first door body, and each extends along the first door body and its corresponding side. The top of each first bracket has an upwardly extending extension.

[0011] The second bracket is removably disposed at the top of the two first brackets and covers the mounting hole and the connecting part. Both ends of the second bracket have bent portions that cooperate with the extension. Along the first direction, the bent portions and the extension are closely fitted to each other and detachably connected.

[0012] In the door assembly provided in this application embodiment, an extension is provided at one end of each of the two first brackets near the second bracket, and a bent portion matching the extension is provided on the second bracket. When the handle and the two first brackets are respectively fixed to the first door body, the second bracket is removably provided at the ends of the two first brackets and covers the connecting portion on the handle and the mounting hole on the first door body. The bent portions at both ends of the second bracket and their corresponding extensions fit together and are detachably connected. Since the second bracket and the first bracket are detachably connected laterally, and the mounting hole on the first door body and the connecting portion passing through the mounting hole are not covered by other components other than the second bracket, the mounting hole and connecting portion can be exposed by removing the second bracket, and the handle can be directly disassembled and replaced, which improves the convenience of handle disassembly, replacement and maintenance and reduces maintenance costs.

[0013] In some embodiments, the door assembly further includes a threaded connector, the extension having one of a through hole and a threaded fixing hole, the bend having the other of the through hole and the threaded fixing hole, and the threaded connector passing through the through hole and threadedly connected to the threaded fixing hole.

[0014] In this way, the detachable connection between the bent part and the extension part is achieved through threaded connectors, which improves the reliability of the connection and reduces the cost of detachable connection between the bent part and the extension part.

[0015] In some embodiments, the bent portion is located outside the corresponding extension portion, and the bent portion has the through hole, while the extension portion has the threaded fixing hole.

[0016] In this way, the second bracket is directly inserted into the top of the two first brackets, and is detachably connected to the extension on the first bracket from both sides of the second bracket through threaded connectors. This makes disassembly and assembly convenient and does not require disassembly of other parts of the door assembly.

[0017] In some embodiments, the bent portion is located inside the corresponding extension portion, and the extension portion has the through hole, while the bent portion is provided with the threaded fixing hole.

[0018] In this way, the second bracket is directly inserted between the extensions at the top of the two first brackets. The second bracket is confined between the two extensions in the first direction, which improves the positional reliability of the second bracket in the first direction. In addition, it is easy to assemble and disassemble without disassembling other parts of the door assembly.

[0019] In some embodiments, the outer edge of the via has a guide structure configured to guide the threaded connector as it passes through the via.

[0020] This improves the accuracy of the threaded connector passing through the through hole and the threaded fixing hole in sequence, thus enhancing the user's operating experience.

[0021] In some embodiments, the guide structure is a tapered hole coaxial with the through hole.

[0022] In this way, the guiding structure is simple, easy to implement, and low in cost.

[0023] In some embodiments, when the bent portion and the extended portion are connected by the threaded connector, the outer end face of the threaded connector is flush with the outer surface of the through hole; and / or,

[0024] The outer surface where the via is located is flush with the outer wall surface of the first bracket; and / or,

[0025] The surface where the threaded fixing hole is located has a recessed platform that is recessed to the side away from the structure where the through hole is located.

[0026] This can improve the overall aesthetics of the door assembly.

[0027] In some embodiments, the second bracket has a clearance notch on the side near the first door body, the clearance notch being configured to avoid the connection portion and the mounting hole.

[0028] This avoids interference between the second bracket and the mounting hole, which would affect the installation of the handle and the second bracket, while also ensuring the overall strength of the second bracket.

[0029] In some embodiments, the extension on each of the first brackets has a first limiting structure at least on the side near the first door body, the first limiting structure extending inward along the first direction, and a first gap forming between the first limiting structure and the surface of the first door body;

[0030] The second bracket has a second limiting structure on the side near the first door body. The second limiting structure is at least partially inserted into the first gap to limit and fix the second bracket in the second direction.

[0031] This allows the second bracket to be limited and fixed in the second direction, thereby improving the installation reliability of the second bracket.

[0032] In some embodiments, the end of the extension facing the first door body has a flange structure extending along the first direction, the flange structure being formed as the first limiting structure; and / or

[0033] The bent portion has a sidewall extending along the first direction on the side near the first door body, and the sidewall is formed as the second limiting structure.

[0034] This results in a simple structure, easy implementation, and low cost.

[0035] In some embodiments, at least one limiting bracket is provided on the side of the first door facing the second bracket, and the at least one limiting bracket is located between the two bent portions at both ends of the second bracket;

[0036] When the second bracket is installed on the first door, the limiting bracket is configured to limit and fix the second bracket in a second direction.

[0037] This design avoids gaps between the second bracket and the first door, thereby improving the overall aesthetics of the door assembly.

[0038] In some embodiments, the second bracket has a sidewall extending along the first direction on the side near the first door body, the limiting bracket has an assembly portion and a limiting portion, the assembly portion is configured to be fixedly connected to the first door body, the limiting portion has a second gap with the first door body, and the portion of the sidewall of the second bracket near the first door body is located within the second gap.

[0039] In this way, the limiting bracket can improve the limiting effect on the second bracket, while the limiting bracket has a simple structure and low cost.

[0040] In some embodiments, when there is only one limiting bracket, the limiting bracket is positioned near the center of the first door body along the first direction; or...

[0041] When there are at least two limiting brackets, the at least two limiting brackets are spaced apart in the first direction.

[0042] This further ensures the limiting effect of the second bracket in the second direction, avoids gaps between the second bracket and the first door body, and improves the aesthetics of the overall structure.

[0043] A second aspect of this application provides a cooking device, including a door assembly as described in the first aspect above.

[0044] The cooking device provided in this application embodiment has the same beneficial effects as the door assembly provided in the above embodiment, and will not be described again here.

[0045] 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 components and 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.

[0073] 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.

[0074] This application provides a cooking device, which includes, but is not limited to, a microwave-steam-grill combo. Taking a microwave-steam-grill combo as an example, the cooking device includes a device body and a door assembly. The device body has a cooking cavity with one side open, which is used to hold food to be cooked. The door assembly is movably disposed at the open side. For example, the bottom end of the door assembly is rotatably connected to the device body. In this way, the cooking cavity can be opened or closed by rotating the door assembly, thereby facilitating the user to take out and put in food. In order to facilitate the user to open and close the door assembly, the door assembly has a handle disposed on the outer wall surface, so as to open or close the door assembly by the handle.

[0075] The structure of the door assembly will be described in detail below with reference to the accompanying drawings. It should be noted that in this article, the orientation of each component in the door assembly is described with the door assembly in the closed state.

[0076] Please refer to Figures 1 to 3As shown, the door assembly 10 includes a first door 100, a second door 500, a third door 600, two first brackets 300, a second bracket 400, a handle 200, and two support members 700. The first door 100, second door 500, and third door 600 include, but are not limited to, glass doors. When the first door 100, second door 500, and third door 600 are all glass doors, they can be referred to as the outer glass, middle glass, and inner glass, respectively. During assembly, the handle 200 is first fixed to the first door 100 with screws. It is understood that the first door 100 has mounting holes 110, through which screws pass and connect to the first door 100. The handle 200... After the handle 200 is installed, the second bracket 400 (i.e., the upper bracket) is fixed to the inside of the first door body 100 (i.e., the side away from the handle 200). Then, two first brackets 300 (i.e., the left bracket and the right bracket) are installed sequentially. The two first brackets 300 are symmetrically arranged on both sides of the second bracket 400 along the width direction (i.e., the first direction) of the first door body 100, and the two first brackets 300 extend along the extension direction of the first door body 100 and its corresponding side, that is, they extend along the second direction, for example, the height direction of the first door body 100. The two first brackets 300 are connected to the corresponding positions of the second bracket 400 by screws, and the connection points between the second bracket 400 and the two first brackets 300 are located inside the two first brackets 300. Figure 2 In this design, the bottom of both ends of the second bracket 400 has fixing holes, and the inner ends of the two first brackets 300 are fixedly connected to the fixing holes with screws. Then, the second door body 500 and the third door body 600 are installed again, with the second door body 500 located between the first door body 100 and the third door body 600. Finally, two support members 700 are placed at the ends of the second door body 500 and the third door body 600 away from the second bracket 400 and fixedly connected to the first bracket 300, with one support member 700 corresponding to one first bracket 300. In this way, the second door body 500 and the third door body 600 are vertically confined between the second bracket 400 and the two support members 700.

[0077] When handle 200 needs to be replaced, since the second bracket 400 blocks the mounting hole 110, the second bracket 400 needs to be removed first. However, the second bracket 400 is internally connected to the first bracket 300. Therefore, to remove the second bracket 400, the support 700, the third door body 600 and the second door body 500 need to be removed in sequence to expose the fixing position of the second bracket 400 and the first bracket 300. After that, the two first brackets 300 can be removed before the second bracket 400 can be removed.

[0078] Therefore, in the above solution, if the handle 200 needs to be replaced or repaired, the left and right support blocks, inner glass, middle glass, left and right brackets and upper bracket must all be removed in sequence before the handle 200 can be removed. This makes it inconvenient to replace or repair the handle 200, which is not conducive to the quick removal, replacement and repair of the handle 200, thus increasing the maintenance cost.

[0079] To address the aforementioned issues, this application provides a door assembly 10, which aims to solve the problem of inconvenient removal, replacement, and repair of the handle 200, resulting in high maintenance costs. This improves the disassembly and assembly speed of the handle 200, reduces the difficulty of disassembly and assembly, and lowers maintenance costs.

[0080] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0081] The door assembly 10 provided in this application embodiment includes a first door body 100 and a handle 200. The first door body 100 has a mounting hole 110. The handle 200 has a connecting portion 210, which passes through the mounting hole 110 and is detachably connected to the first door body 100. For example, the connecting portion 210 includes, but is not limited to, a screw that is an independent structure from the handle 200. In this way, the handle 200 can be fixed to the outside of the first door body 100 through the connecting portion 210, so that the user can open or close the door assembly 10 through the handle 200.

[0082] Please refer to Figure 4 and Figure 5 As shown, the door assembly 10 also includes two first brackets 300 and a second bracket 400. The two first brackets 300 are symmetrically arranged on the side of the first door 100 away from the handle 200 along a first direction (e.g., the width direction of the door assembly 10). Each first bracket 300 has an upwardly extending extension 310 at its top end. That is, the top end of the first bracket 300 (the end opposite to the bottom end of the door assembly) has an extension 310 extending towards the top end of the door assembly 10 along a second direction. The second bracket 400 is removably arranged at the top end of the two first brackets 300 along the second direction and covers the mounting hole 110 and the connecting part 210. Both ends of the second bracket 400 have a bent part 410 that cooperates with the extension 310. Along the first direction, the bent part 410 and the extension 310 fit together and are detachably connected.

[0083] The second direction is the same as the extension direction of the first bracket 300, that is, the second direction is the height direction of the door assembly 10.

[0084] It is understandable that the fixed connection between the first bracket 300 and the second bracket 400 is not located inside the door assembly 10, but is set at the ends of both ends of the second bracket 400, and is connected to the first bracket 300 through both sides of the second bracket 400. In this way, the second door 500 and the third door 600 installed on the first bracket 300 will not block the connection between the first bracket 300 and the second bracket 400. Therefore, it is not necessary to completely remove the second door 500 and the third door 600. Only the connection between the extension 310 on the first bracket 300 and the bend 410 on the second bracket 400 needs to be removed to remove the second bracket 400 from the door assembly 10. After removing the second bracket 400, the mounting hole 110 and the connecting part 210 that are fixedly connected to the handle 200 and the first door 100 can be exposed, which facilitates the quick removal, replacement or repair of the handle 200, improves the convenience of disassembly, replacement and repair of the handle 200, and reduces maintenance costs.

[0085] like Figures 4 to 7 As shown, the extension 310 is disposed on the outer side wall of the corresponding first bracket 300 along a first direction (such as the left-right direction) and extends vertically, while the bending portion 410 is the two ends of the second bracket 400 extending vertically downwards respectively. In this way, when the first bracket 300 and the second bracket 400 are connected, the extension 310 of the first bracket 300 near the outside and the bending portion 410 at the end of the second bracket 400 fit together and are detachably connected. This connection is independent of the internal structure of the door assembly 10. Therefore, when disassembling the second bracket 400, it is not necessary to remove the first bracket 300, the second door 500, the third door 600 and the support member 700, etc. This allows for quick disassembly of the second bracket 400, facilitating the disassembly, replacement and maintenance of the handle 200, thereby solving the problem of difficult maintenance of the handle 200.

[0086] Both the extension 310 and the bending part 410 can be plate-like structures, as long as they have sufficient strength and rigidity, and there are no restrictions here.

[0087] In some embodiments, the door assembly 10 further includes a threaded connector. The extension 310 has one of a through hole 411 and a threaded fixing hole 311, and the bend 410 has the other of a through hole 411 and a threaded fixing hole 311. The threaded connector passes through the through hole 411 and is threadedly connected to the threaded fixing hole 311. In this way, the extension 310 and its corresponding bend 410 can be detachably connected by the threaded connector, which improves the reliability and convenience of the connection and reduces the cost of detachably connecting the bend 410 and the extension 310.

[0088] For example, the threaded connector is a screw, and the threaded fixing hole 311 has an internal thread that matches the screw, so that the screw can be screwed in and threaded into the internal thread.

[0089] like Figures 4 to 7 As shown, the bent portion 410 has a through hole 411, and the extension portion 310 has a threaded fixing hole 311. When the second bracket 400 and the first bracket 300 are installed, the bent portion 410 is located outside the extension portion 310. In this way, the threaded connector can pass through the through hole 411 on the bent portion 410 and be fixedly connected to the threaded fixing hole 311 on the extension portion 310.

[0090] like Figures 8 to 12 As shown, during installation of the second bracket 400 and the first bracket 300, the handle 200 is first connected to the first door body 100 through the connecting part 210 via the mounting hole 110. Then, the second bracket 400 can be fixed to the first door body 100, and the extension 310 of the first bracket 300 is inserted into the second bracket 400, so that the bent part 410 is located outside the extension 310 and at least partially conforms to the surface of the extension 310. Alternatively, after stretching installation, the first bracket 300 can be fixed to the first door body 100, and the second bracket 400 can be inserted from top to bottom into the top of the first bracket 300 (e.g., ...). Figure 11 and Figure 12 (As shown), then, screws are passed through the through hole 411 on the bent part 410 and the threaded fixing hole 311 on the extension part 310 to connect them. When disassembling, the screws connecting the bent part 410 and the extension part 310 can be removed from the side of the door assembly 10 to complete the disassembly of the second bracket 400. The disassembly method is convenient and quick, which makes it convenient to disassemble, replace or repair the handle 200.

[0091] In other embodiments, please refer to Figures 14 to 17 As shown, a through hole 411 is provided on the extension 310, and a threaded fixing hole 311 is provided on the bend 410. When the first bracket 300 and the second bracket 400 are connected, the extension 310 is located outside the bend 410. During installation, the second bracket 400 is located between the two opposite extensions 310 on the two first brackets 300, and the bends 410 at both ends of the second bracket 400 are respectively in contact with at least part of the surface of the corresponding extension 310. Then, the screw passes through the through hole 411 on the extension 310 and is fixedly connected to the threaded fixing hole 311 on the bend 410. During disassembly, the screw only needs to be removed from the side of the door assembly 10 to complete the disassembly of the second bracket 400. The disassembly is simple and quick. In addition, by setting the second bracket 400 between the two opposite extensions 310, the second bracket 400 can be limited in the first direction, thereby improving the positional reliability of the second bracket 400 in the first direction.

[0092] When the threaded connector connects the extension 310 and the bend 410, in order to improve the accuracy of the threaded connector passing through the through hole 411 and the threaded fixing hole 311, in this embodiment of the application, the outer edge of the through hole 411 has a guide structure 412. The guide structure 412 is configured to guide the threaded connector when it passes through the through hole 411. In this way, the accuracy of the threaded connector passing through the through hole 411 and the threaded fixing hole 311 in sequence is improved, and the user's operating experience is enhanced.

[0093] For example, such as Figure 4 and Figure 12 As shown, when the through hole 411 is provided on the bent portion 410, a guide structure 412 is provided on the outer wall of the bent portion 410 at the outer edge of the through hole 411; as Figure 17 As shown, when the through hole 411 is provided on the extension 310, a guide structure 412 is also provided on the outer edge of the through hole 411 on the outer side wall of the extension 310. In this way, whether the through hole 411 is provided on the bending part 410 or the extension 310, a guide structure 412 is provided on the outer edge of the through hole 411 to guide the threaded connector, so as to improve the accuracy of the threaded connector passing through the through hole 411 and thus improve the user's experience.

[0094] like Figure 4 , Figure 12 as well as Figure 17 As shown, the guide structure 412 can be a tapered hole coaxial with the through hole 411, so as to guide the threaded connector through the tapered surface of the tapered hole, so that the threaded connector can be accurately inserted into the through hole 411. The guide structure 412 is simple, easy to implement, and low in cost.

[0095] It is understandable that, along the first direction, from the outside to the inside of the door assembly 10, the diameter of the tapered hole decreases sequentially until it is equal to the diameter of the through hole 411, thereby facilitating the insertion of the threaded connector into the through hole 411.

[0096] In addition, whether the threaded fixing hole 311 is located on the extension 310 or the bend 410, the surface where the threaded fixing hole 311 is located has a countersunk platform 312 that is recessed toward the side away from the structure where the through hole 411 is located. The threaded fixing hole 311 is provided on the countersunk platform 312. It can be understood that the countersunk platform 312 can be used to avoid the nut of the threaded connector, or, by providing the countersunk platform 312, the position of the internal thread in the threaded fixing hole 311 in the first direction can be changed so that it corresponds to the position of the external thread on the threaded connector, thereby realizing the threaded connection.

[0097] An example, such as Figures 5 to 7In this example, a threaded fixing hole 311 is provided on the extension 310, and a countersunk plate 312 is provided on the outer surface of the extension 310, with the threaded fixing hole 311 disposed on the countersunk plate 312; another example is... Figure 16 As shown, the threaded fixing hole 311 is provided on the bent part 410, and a countersunk platform 312 is provided on the outer surface of the bent part 410, and the threaded fixing hole 311 is provided on the countersunk platform 312.

[0098] like Figure 9 As shown, the bent portion 410 is provided on the outside of the extension portion 310, and the threaded fixing hole 311 is provided on the extension portion 310. Since the thickness of the bent portion 410 in the first direction is small, in order to ensure the size of the guide structure 412 and the through hole 411, the bent portion 410 has a protrusion recessed towards one side of the extension portion 310. The guide structure 412 and the through hole 411 are provided on the protrusion. In this way, the countersunk platform 312 can also be used to avoid the protrusion on the bent portion 410, so as to avoid interference between the protrusion on the bent portion 410 and the extension portion 310.

[0099] Of course, when the via 411 is provided on the extension 310, a protrusion extending toward the side of the bend 410 may also be provided on the extension 310. Correspondingly, the guide structure 412 and the via 411 are provided on the protrusion, and the countersunk 312 on the bend 410 can also be used to avoid the protrusion on the extension 310.

[0100] In addition, whether the extension 310 is located outside the bend 410 or the bend 410 is located outside the extension 310, when the bend 410 and the extension 310 are connected, the outer end face of the threaded connector is flush with the outer surface of the through hole 411. For example, when the threaded connector is a screw, the end face of the screw nut is flush with the outer surface of the through hole 411, thereby improving the overall aesthetics of the door assembly 10. In addition, it can also prevent interference between the threaded connector and the door assembly 10 or other parts of the cooking equipment.

[0101] To further enhance the aesthetics of the overall structure of the door assembly 10, the outer surface where the through hole 411 is located is flush with the outermost surface of the first bracket 300.

[0102] Please refer to Figure 10 As shown, the second bracket 400 has a clearance notch 430 on the side near the first door body 100. The clearance notch 430 is configured to avoid the mounting hole 110. In this way, interference between the second bracket 400 and the mounting hole 110 is avoided, thereby avoiding interference with the connecting part 210 passing through the mounting hole 110, which would affect the installation of the handle 200 and the second bracket 400.

[0103] In addition, such as Figure 10As shown, the clearance notch 430 matches the mounting hole 110. In other words, the clearance notch 430 adopts a partial clearance, only clearing the mounting hole 110, rather than completely cutting off the lower end of the second bracket 400, thereby ensuring the overall strength of the second bracket 400.

[0104] Please return to the reference. Figure 7 As shown, the extension 310 on each first bracket 300 has a first limiting structure 320 on at least one side near the first door body 100. The first limiting structure 320 extends inward along a first direction, and a first gap is formed between the first limiting structure 320 and the surface of the first door body 100. The second bracket 400 has a second limiting structure 420 on one side near the first door body 100. The second limiting structure 420 is at least partially inserted into the first gap to limit and fix the second bracket 400 in a second direction. In this way, the second bracket 400 can be limited and fixed in a second direction to improve the installation reliability of the second bracket 400.

[0105] For example, in Figure 7 In the design, the extension 310 has a flange structure extending in a first direction at one end facing the first door 100, and the flange structure forms a first limiting structure 320; in addition, the bending portion 410 has a side wall extending in the first direction on the side near the first door 100, and the side wall forms a second limiting structure 420. Thus, when the second bracket 400 is connected to the first bracket 300, part of the side wall of the bending portion 410 is located in the first gap formed between the flange structure and the first door 100, so as to limit the second bracket 400 in the front-back direction. The flange structure can be integrated with the extension 310, and the second limiting structure 420 can be integrated with the bending portion 410. The structure is simple, easy to implement, and low in cost.

[0106] Please continue to refer to Figure 7 As shown, the extension 310 has flange structures extending in the first direction on both the front and rear sides. When the second bracket 400 is connected to the first bracket 300, the flange structures on both the front and rear sides of the extension 310 are inserted into the second bracket 400 to limit the front and rear direction of the first bracket 300. In this way, the first bracket 300 and the second bracket 400 limit each other in the front and rear direction, thereby improving the positional reliability of the first bracket 300 and the second bracket 400 in the front and rear direction.

[0107] like Figure 4 , Figure 10 , Figures 14 to 16As shown, the second bracket 400 is a long strip structure extending along the first direction. When the two ends of the second bracket 400 are fixedly connected to the corresponding first bracket 300, the area of ​​the second bracket 400 near the middle is prone to deformation, which causes a gap to form between the second bracket 400 and the first door body 100 bracket, affecting the overall appearance and refinement.

[0108] To address the above issues, please refer to the embodiments of this application. Figure 4 As shown, at least one limiting bracket 120 is provided on the side of the first door body 100 facing the second bracket 400. The at least one limiting bracket 120 is located between the two bent portions 410 at both ends of the second bracket 400. When the second bracket 400 is provided on the first door body 100, the limiting bracket 120 is configured to limit and fix the second bracket 400 in the second direction to avoid the formation of a gap between the second bracket 400 and the first door body 100, thereby improving the overall appearance of the door assembly 10.

[0109] Please refer to Figure 13 As shown, the second bracket 400 has a sidewall extending in a first direction on the side near the first door body 100. The limiting bracket 120 has an assembly part 121 and a limiting part 122. The assembly part 121 is configured to be fixedly connected to the first door body 100. There is a second gap between the limiting part 122 and the first door body 100. The part of the sidewall of the second bracket 400 near the first door body 100 is located in the second gap. In this way, the limiting bracket 120 enhances the limiting effect on the second bracket 400, while the limiting bracket 120 has a simple structure and low cost.

[0110] For example, when there is one limiting bracket 120, the limiting bracket 120 is disposed near the middle of the first door body 100 along the first direction; for other examples, when there are at least two limiting brackets 120, at least two limiting brackets 120 are disposed at intervals in the first direction, and the specific number can be selected according to the length of the second bracket 400. In this way, the limiting bracket 120 can further ensure the limiting effect of the second bracket 400 in the second direction, avoid deformation of the second bracket 400 near the middle and the formation of a gap between it and the first door body 100, and improve the aesthetics of the overall structure.

[0111] like Figure 13 As shown, the assembly part 121 has an assembly surface that matches the first door body 100. The assembly part 121 can be fixedly connected to the first door body 100 by means of screws or adhesives. The limiting part 122 is a limiting plate that matches the side wall of the second bracket 400, increasing the contact area with the side wall of the second bracket 400, thereby improving the limiting effect on the front and rear directions of the second bracket 400.

[0112] In the door assembly provided in this application embodiment, an extension is provided at one end of each of the two first brackets near the second bracket, and a bent portion matching the extension is provided on the second bracket. When the handle and the two first brackets are respectively fixed to the first door body, the second bracket is removably provided at the ends of the two first brackets and covers the connecting portion on the handle and the mounting hole on the first door body. The bent portions at both ends of the second bracket and their corresponding extensions fit together and are detachably connected. Since the second bracket and the first bracket are detachably connected laterally, and the mounting hole on the first door body and the connecting portion passing through the mounting hole are not covered by other components other than the second bracket, the mounting hole and connecting portion can be exposed by removing the second bracket, and the handle can be directly disassembled and replaced, which improves the convenience of handle disassembly, replacement and maintenance and reduces maintenance costs.
