[0032] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Example 1

[0036] See Figures 1 to 3 This utility model discloses a door assembly, see details. Figure 3 The door assembly includes a mounting frame, a door seal assembly, and a door panel 10; wherein the door seal assembly is detachably installed within the mounting frame, and the door panel 10 is detachably installed on one side of the mounting frame.

[0037] Based on this structure, when using the door assembly of this utility model, during assembly, the door seal assembly can first be installed in the mounting frame using a detachable connection method, such as by fasteners 34 such as screws and bolts, or by a snap-fit ​​structure. Then, the door panel 10 is also installed on one side of the mounting frame using fasteners 34 such as screws and bolts, or by a detachable connection method such as a snap-fit ​​structure. The assembled door assembly is then connected to the cooking chamber of the cooking equipment, so that the door assembly can seal the cooking cavity during cooking, providing a sealed cooking environment.

[0038] When door components are damaged and require repair, such as scratches on the surface of the door panel 10 affecting its appearance, or a decrease in the sealing performance of the door seal assembly leading to temperature and odor leaks, or when a deep cleaning of the mounting frame and door seal assembly is needed, simple operations can be performed. For example, the screws, bolts, and other fasteners 34 can be removed, and then the door panel 10 can be removed from the mounting frame, followed by the removal of the door seal assembly within the mounting frame. Alternatively, the door panel 10 and door seal assembly can be pushed in the opposite direction to the snap-fit ​​direction to disengage the snap-fit ​​parts, thereby allowing the door panel 10 and door seal assembly to be removed separately. At this point, individual component replacement or cleaning can be easily performed.

[0039] The door seal assembly, installed within the mounting frame, provides a good seal when the door is closed. In cooking equipment, the door seal assembly effectively prevents heat, steam, and odor leakage from the cooking cavity, ensuring a stable cooking environment and improving cooking efficiency.

[0040] Therefore, by detachably connecting the mounting frame of the door assembly to the door seal assembly and the door panel 10, this utility model makes it particularly convenient to disassemble the mounting frame, door seal assembly, and door panel 10, thereby improving the ease of maintenance. At the same time, since it eliminates the need for a large-scale replacement of the entire door assembly, maintenance costs are reduced.

[0041] Furthermore, since the various components of the door assembly are detachable, they can be disassembled and packaged for transport, reducing packaging volume and lowering transportation costs. This also avoids the risk of component damage from collisions during transport, ensuring the integrity of the door assembly during transit. Assembly can then be completed upon arrival at the destination, making the process convenient and quick.

[0042] Further, see Figure 3 The mounting frame includes a first frame 20 and a second frame 30, and the first frame 20 and the second frame 30 are detachably connected, wherein the door panel 10 is mounted on one side of the first frame 20.

[0043] Based on this structure, when installing the door assembly, the door seal assembly can first be installed between the first frame 20 and the second frame 30. Then, the first frame 20 and the second frame 30 are assembled using methods such as slot and block engagement or bolt connection. If using a slot and block engagement method, the blocks on the first frame 20 can be aligned with the slots on the second frame 30, and then the two can be forcefully snapped together. If using a bolt connection, holes can be drilled at corresponding positions on the two frames, and then bolts can be used to tighten them. Then, the door panel 10 is installed on one side of the first frame 20 using bolts, clips, and other connecting components.

[0044] When either the first frame 20 or the second frame 30 is damaged, for example, if the edge of the first frame 20 is deformed, the damaged frame can be directly disassembled and replaced without replacing the entire mounting frame.

[0045] Therefore, by dividing the installation frame into a detachable first frame 20 and a second frame 30, the installation process of the door components becomes more modular. This not only saves material costs but also improves maintenance efficiency.

[0046] Furthermore, the first frame 20 includes a first side frame 21 and two side frames 22. Specifically, the two side frames 22 are arranged opposite to each other, and the two side frames 22 are detachably installed on the side of the first side frame 21 facing the door panel 10. The door panel 10 is detachably connected to the sides of the two side frames 22 respectively.

[0047] Furthermore, the second frame 30 includes a second border 31. Specifically, the second border 31 surrounds the outer periphery of the first frame 20, and the two opposite end faces of the second border 31 are respectively connected to the end faces of the two side frames 22 by fasteners 34. One side of the second border 31 extends inward to form a limiting frame 32, and the limiting frame 32 abuts against one side of the first border 21.

[0048] Based on this structure, during installation, the two side frames 22 are first installed onto the side of the first frame 21. Specifically, the side frames 22 and the first frame 21 can be connected using fasteners 34 such as bolts and screws, or through a snap-fit ​​structure. If bolts are used, holes are drilled at corresponding positions on the side frames 22 and the first frame 21, then bolts are passed through the holes and nuts are tightened, so that the two side frames 22 are fixed relative to each other on the side of the first frame 21 facing the door panel 10. If snap-fit ​​is used, the snaps on the side frames 22 are aligned with the slots on the first frame 21, and they are pressed firmly to engage. The door panel 10 is then installed onto the side frames 22, using the same connection method described above. Finally, the second frame 31 of the second frame 30 is fixed to the end face of the side frames 22 using fasteners 34.

[0049] When it is necessary to disassemble the door assembly, the fasteners 34 at both ends of the second frame 31 can be removed first, thereby removing the second frame 31 from the outer periphery of the first frame 20. Then, the door panel 10 can be removed from the side frame 22, and then the side frame 22 can be disassembled. This makes it convenient to conduct a comprehensive inspection and maintenance of each component.

[0050] The second frame 31 surrounds the outer periphery of the first frame 20 and is connected to the side frame 22 by fasteners 34, enhancing the overall structural integrity of the entire door assembly. The limiting frame 32 on the second frame 31 abuts against one side of the first frame 21, serving a positioning and fixing function, preventing the first frame 20 from shifting or shaking during use, and further improving the stability and sealing of the door assembly.

[0051] Therefore, by further dividing the first frame 20 into the first side frame 21 and the side frame 22, the installation process of the door assembly is made more modular, which facilitates the preparation and installation of each component, and finally the overall assembly, which greatly improves the installation efficiency and shortens the installation time.

[0052] Furthermore, the door sealing assembly includes a sealing assembly 40, wherein the sealing assembly 40 includes a cover plate 41 and a mounting bracket 42, see reference. Figure 7 The first frame 21 is provided with a first mounting groove 211, see reference. Figure 6 The mounting bracket 42 is installed in the first mounting slot 211, and the mounting bracket 42 is provided with a second mounting slot 421, see reference. Figure 5 The cover plate 41 is installed in the second mounting slot 421.

[0053] Based on this structure, during assembly, the mounting bracket 42 is first installed into the first mounting groove 211 of the first frame 21, and then the cover plate 41 is installed into the second mounting groove 421 of the mounting bracket 42. Specifically, both the first frame 21 and the mounting bracket 42 can be made of metal materials such as stainless steel or aluminum alloy, so that the mounting bracket 42 can be welded into the first mounting groove 211. The cover plate 41 can be a tempered glass plate, and the cover plate 41 can be attached to the mounting bracket 42 by adhesive.

[0054] Therefore, when the cover plate 41 is damaged, since it is glued to the mounting bracket 42, a new tempered glass cover plate 41 can be easily replaced simply by carefully removing the glue. If the mounting bracket 42 has a problem, although it is welded to the first frame 21, it can be replaced by cutting the weld points with professional tools during maintenance, which greatly reduces maintenance costs and time compared to replacing the entire door seal assembly.

[0055] Furthermore, the first frame 21 and the mounting bracket 42 are made of metal, both of which can withstand the impact and friction caused by frequent opening and closing of the door, and are not easily deformed or damaged. The cover plate 41 is made of tempered glass, which has good light transmission, allowing users to clearly observe the cooking status of the food inside the cooking device without having to frequently open the door, reducing heat loss and changes in the cooking environment, and helping to improve cooking quality.

[0056] In addition, the second frame 30 can be made of plastic material. The second side frame 31 of the second frame 30 surrounds the outer perimeter of the first side frame 21, and the two end faces of the second side frame 31 are connected to the side frame 22 of the first frame 20 by fasteners such as screws 34.

[0057] Furthermore, the sealing assembly 40 also includes a first seal 43 and a second seal 44, wherein the first seal 43 is sealingly disposed between the inner periphery of the first mounting groove 211 and the outer periphery of the mounting bracket 42. (See reference...) Figure 7 The first frame 21 is also provided with a third mounting groove 212, and the third mounting groove 212 surrounds the outer periphery of the first mounting groove 211, see reference. Figure 4 The inner end of the limiting frame 32 extends away from the limiting frame 32 to form a snap-fit ​​edge 33, and the snap-fit ​​edge 33 is installed in the third mounting groove 212. The second sealing member 44 is sealed between the snap-fit ​​edge 33 and the groove wall of the third mounting groove 212.

[0058] Based on this structure, during assembly, the mounting bracket 42 can be installed in the first mounting groove 211 first, and then the first sealing member 43 can be installed between the inner circumference of the first mounting groove 211 and the outer circumference of the mounting bracket 42. Furthermore, when connecting the first frame 20 and the second frame 30, the second sealing member 44 can be installed in the third mounting groove 212 first, and then the two ends of the second frame 31 can be connected to the end faces of the two side frames 22 using fasteners 34. Simultaneously, the snap-fit ​​edge 33 on the second frame 31 can be snapped into the third mounting groove 212 of the first frame 21 and connected to the second sealing member 44. Subsequently, the limiting frame 32 on the second frame 31 abuts against one side of the first frame 21.

[0059] Both the first sealing element 43 and the second sealing element 44 can be sealing rings made of elastic materials such as rubber and silicone. The first sealing element 43 deforms under the pressure of the inner circumference of the first mounting groove 211 and the outer circumference of the mounting bracket 42, thereby sealing the gap between the inner circumference of the first mounting groove 211 and the outer circumference of the mounting bracket 42, preventing odors and fumes from escaping from the inner gap to the outside of the door assembly during cooking. The second sealing element 44 deforms under the pressure of the snap-fit ​​edge 33 and the groove wall of the third mounting groove 212, thereby making the connection between the second frame 31 and the first frame 21 more secure.

[0060] When it is necessary to inspect or replace the seal, the two ends of the second frame 30 can be disassembled from the side frame 22, for example, by removing the fasteners 34 on it. Then, external force is applied to move the limiting frame 32 of the second frame 30 away from the first side frame 21, so that the snap-fit ​​edge 33 is disengaged from the third mounting groove 212. The second seal 44 can then be easily removed for inspection or replacement. For the first seal 43, external force can be applied to disassemble it directly.

[0061] In addition, when the door assembly is installed with the cooking chamber, the first seal 43 seals the connection between the door assembly and the cooking chamber, preventing heat, steam and odors in the cooking chamber from leaking from the connection between the door assembly and the cooking chamber.

[0062] Furthermore, the door sealing assembly also includes a heat insulation plate 50, specifically, the heat insulation plate 50 is disposed on the side of the first frame 21 facing the door panel 10, see reference. Figure 8 Two side frames 22 are positioned opposite each other at both ends of the heat insulation plate 50. A heat insulation cavity 51 is formed between the heat insulation plate 50 and the door panel 10. (See reference...) Figure 9 The side frame 22 includes a first side frame 23 and a second side frame 24. The first side frame 23 and the second side frame 24 are disposed opposite to each other on both sides of the heat insulation plate 50, and the first side frame 23 and the second side frame 24 are detachably connected and respectively supported on both sides of the heat insulation plate 50.

[0063] Based on this structure, during assembly, the heat insulation plate 50 is first placed at a predetermined position between the first frame 21 and the door panel 10. Then, the first side frame 23 and the second side frame 24 are installed from both sides of the heat insulation plate 50, and the two sets of first side frames 23 and second side frames 24 are installed at both ends of the heat insulation plate 50. The first side frame 23 and the second side frame 24 are supported on both sides of the heat insulation plate 50 by a detachable connection, such as using bolts, clips, or other connectors; the two side frames 22 are respectively supported at both ends of the heat insulation plate 50.

[0064] When the cooking appliance is in operation, high temperatures are generated inside the cooking cavity. At this time, the heat insulation plate 50 begins to function, effectively preventing heat from being transferred from the first frame 21 to the door panel 10. Since a heat insulation cavity 51 is formed between the heat insulation plate 50 and the door panel 10, the heat insulation effect is further enhanced. When the user operates the door, even if the inside of the cooking appliance is at a high temperature, the surface temperature of the door panel 10 will not be too high, thus avoiding the risk of burns to the user.

[0065] During the opening and closing of the door, the first side frame 23 and the second side frame 24 of the side frame 22 will move with the movement of the door. However, since their connection with the heat insulation board 50 is stable, they will not affect the position and heat insulation performance of the heat insulation board 50.

[0066] When the heat insulation panel 50 is damaged, such as when its heat insulation performance deteriorates, the first side frame 23 and the second side frame 24 can be disassembled to easily replace the heat insulation panel 50, ensuring that the heat insulation performance of the door assembly is always good.

[0067] Therefore, by setting up the heat insulation plate 50 and forming a heat insulation cavity 51 between the heat insulation plate 50 and the door panel 10, the heat transfer from the cooking cavity to the surface of the door panel 10 can be effectively reduced, improving the safety of using the cooking device. The detachable connection between the first side frame 23 and the second side frame 24 of the side frame 22 and the heat insulation plate 50 facilitates the maintenance and replacement of the heat insulation plate 50. When the heat insulation plate 50 is damaged or its performance deteriorates, it is not necessary to disassemble the entire door assembly; only the side frame 22 needs to be removed to repair or replace the heat insulation plate 50.

[0068] In addition, the first side frame 23 and the second side frame 24 are respectively supported on both sides of the heat insulation plate 50, which not only provides stable support for the heat insulation plate 50, but also enhances the overall structural stability of the door assembly.

[0069] Furthermore, the first side frame 23 includes a side plate, the top and bottom ends of which extend toward the second side frame 24 to form a connecting plate 25. The second side frame 24 includes a column, and the top and bottom of the column are provided with connecting portions 26, wherein the connecting plate 25 and the connecting portions 26 are connected by fasteners 34. In addition, the upper and lower ends of the column are respectively provided with guide hooks 27, which are detachably installed on the column, and the guide hooks 27 are provided with guide grooves, into which the edge of the heat insulation plate 50 is embedded.

[0070] Based on this structure, during assembly, the guide hooks 27 are first installed at the upper and lower ends of the columns. Specifically, the guide hooks 27 are equipped with connecting posts, and the columns are equipped with corresponding connecting holes, into which the connecting posts can be inserted. When installing the heat insulation plate 50, the lower edge of the heat insulation plate 50 is embedded into the guide grooves of the lower guide hooks 27 of the two columns, and the upper edge of the heat insulation plate 50 is embedded into the guide grooves of the upper guide hooks 27 of the two columns. Then, the side plate of the first side frame 23 is brought close to the other side of the heat insulation plate 50, and the connecting plate 25 of the first side frame 23 is connected to the connecting part 26 on the column of the second side frame 24 using fasteners 34 such as screws, so that the first side frame 23 and the second side plate are located on both sides of the heat insulation plate 50.

[0071] When it is necessary to repair or replace the side frame 22 or the heat insulation plate 50, first disassemble the connection between the connecting plate 25 and the column, and then the heat insulation plate 50 can be easily slid out along the guide groove.

[0072] Thus, the guide hook 27 limits the heat insulation plate 50 between the first side frame 23 and the second side frame 24, further enhancing the stability of the entire structure. When the heat insulation plate 50 is damaged or its performance deteriorates, the guide hook 27 and fastener 34 can be easily removed for individual repair or replacement of the heat insulation plate 50, the first side frame 23, or the second side frame 24, reducing maintenance and time costs.

[0073] Furthermore, it should be noted that the first side frame 23 and the second side frame 24 can be made of engineering plastics, aluminum alloys, or other materials. When the heat insulation plate 50 expands due to heat, the first side frame 23 and the second side frame 24, made of engineering plastics or aluminum alloys, can deform to a certain extent due to their elasticity. This deformation can absorb the stress generated by the expansion of the heat insulation plate 50, preventing stress concentration on the heat insulation plate 50 and thus avoiding its explosion.

[0074] Furthermore, a snap-fit ​​member 28 is provided between the first side frame 23 and the second side frame 24. Specifically, the snap-fit ​​member 28 includes a mounting part and a snap-fit ​​part. The mounting part is connected to the first side frame 23 by a fastener 34. The first side frame 23 is also provided with a first through hole 231, the first frame 21 is provided with a second through hole 213, and the second frame 31 is provided with a third through hole 35. The snap-fit ​​part passes through the first through hole 231, the second through hole 213, and the third through hole 35 in sequence, and the snap-fit ​​part is used to snap into the snap-fit ​​groove on the cooking equipment.

[0075] Based on this structure, when installing the door assembly onto the cooking equipment, the mounting part of the snap-fit ​​member 28 is first fixed to the first side frame 23 using fasteners 34 such as bolts and nuts, ensuring that the mounting part is securely connected to the first side frame 23. Next, the snap-fit ​​part of the snap-fit ​​member 28 is sequentially passed through the first through hole 231 of the first side frame 23, the second through hole 213 of the first frame 21, and the third through hole 35 of the second frame 31, and then snapped into the snap-fit ​​groove on the cooking equipment, thereby securely installing the door assembly onto the cooking equipment.

[0076] During normal use of the cooking equipment, the snap-fit ​​component 28 maintains a connection between the door assembly and the cooking equipment. Because the snap-fit ​​part fits tightly with the snap-fit ​​groove, the door assembly remains stably installed on the cooking equipment even with frequent opening and closing of the door, without shaking or falling off.

[0077] When it is necessary to disassemble the door assembly, simply remove the snap-fit ​​28 from the snap-fit ​​slot to easily remove the door assembly from the cooking equipment.

[0078] This ensures the stability of the connection between the door assembly and the cooking equipment, while also facilitating the installation and disassembly of the door assembly, thus improving the assembly and maintenance efficiency of the entire cooking device.

[0079] Furthermore, the mounting frame also includes a top plate 60. Specifically, the top plate 60 is disposed on the top of the first frame 20 and the second frame 30. The two ends of the top plate 60 are detachably connected to the first frame 20, and the bottom of the top plate 60 abuts against the top of the second frame 30.

[0080] Based on this structure, during the installation process, the first frame 20 and the second frame 30 are first assembled, then the top plate 60 is moved to the top position of the first frame 20 and the second frame 30, and the two ends of the top plate 60 are installed on the first frame 20 with fasteners 34 such as screws and bolts, so that its bottom is tightly against the top of the second frame 30.

[0081] When it is necessary to inspect or repair the door seal assembly inside the mounting frame, the top plate 60 can be removed first, and then the fasteners 34 at both ends of the second frame 30 can be removed to disconnect it from the side frame 22. At this time, the second frame 30 can be removed as a whole, and then the first frame 20 and the various parts of the door seal assembly can be disassembled.

[0082] Therefore, when the door is opened or closed, the top plate 60, the first frame 20, and the second frame 30 jointly bear the weight of the door and various forces generated during the opening and closing process.

[0083] In addition, the door panel 10 can be a glass panel, and the side of the door panel 10 away from the mounting frame is also provided with a handle 101, which can be locked onto the door panel 10 with screws.

[0084] Example 2

The door assembly is detachably hinged to the cooking chamber, the cooking chamber has a cooking cavity, and the door assembly is used to move closer to or further away from the cooking cavity during rotation relative to the cooking chamber to cover or open the cooking cavity.

[0086] Based on this structure, during the assembly of the cooking device, the assembled door assembly is installed onto the cooking box by means of hinges. Specifically, the door can be connected to the cooking box body by door hinges or hinges, or the rotation can be achieved by installing pivots at the top and bottom of one end of the door body and cooperating with the pivot holes of the box body.

[0087] In daily use, users can open or close the cooking cavity by rotating the door assembly. When the door assembly malfunctions and requires repair or deep cleaning, users can disassemble the hinge connector and remove the door assembly from the cooking oven for repair or cleaning.

[0088] Since all components of the door assembly are detachable, they can be easily disassembled for replacement, cleaning, and other tasks.
