[0002] Currently, the various parts of the door assembly of cooking appliances are fixed together with screws. When disassembling the door assembly for cleaning, tools are required, making the cleaning of the door assembly quite cumbersome. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first aspect of the present invention provides a door assembly.

[0005] A second aspect of the invention also provides a cooking utensil.

[0006] In view of the above, a first aspect of the present invention provides a door assembly for a cooking appliance, the cooking appliance including a housing, the door assembly being movably connected to the housing for opening or closing the housing, the door assembly including: at least two supports, the at least two supports being arranged opposite to each other, the supports having a first limiting groove and a first engaging portion; a first door panel, disposed between the at least two supports, the first door panel including a first end and a second end arranged opposite to each other, and a third end and a fourth end arranged opposite to each other, the first end and the second end of the first door panel being respectively inserted into the first limiting groove of the at least two supports, the third end of the first door panel being limited and engaged with the supports; an end cap, disposed at the fourth end of the first door panel, and the end cap being respectively connected to the supports on both sides of the first door panel; wherein the end cap has at least two second engaging portions, the first engaging portion engaging with the second engaging portion to make the end cap detachably connected to the at least two supports.

[0007] The door assembly provided by this invention is used in a cooking appliance. The door assembly is movably connected to the appliance's housing, allowing the housing to be opened or closed. The door assembly includes at least two brackets, a first door panel, and an end cap. The at least two brackets are arranged opposite each other, and the first door panel is positioned between the at least two brackets. The first and second ends of the first door panel are respectively inserted into the first limiting grooves of the at least two brackets, enabling rapid assembly of the first door panel and the at least two brackets. Simultaneously, the third end of the first door panel engages with the bracket for limiting, and the end cap is positioned at the fourth end of the first door panel, fixing the first door panel and preventing it from shifting. The end cap engages with the first locking parts on the at least two brackets via a second locking part, allowing the brackets, the first door panel, and the end cap to be detachably connected. This enables rapid disassembly and assembly of the door assembly without the need for additional tools, improving the speed of disassembly and assembly and the cleanliness of the door assembly.

[0008] In some embodiments, the bracket may optionally include a third snap-fit ​​portion located at one end of the first limiting groove near the end cover, and the third snap-fit ​​portion snaps into the fourth end of the first door panel.

[0009] In this embodiment, the bracket is also provided with a third snap-fit ​​part, which is located at one end of the first limiting groove near the end cover. When the first door panel is installed in the first limiting groove, the third snap-fit ​​part snaps with the fourth end of the first door panel, so that the first door panel is fixed in the first limiting groove and the first door panel is prevented from moving.

[0010] In some embodiments, the third snap-fit ​​portion may optionally be an elastic structure.

[0011] In this embodiment, the third latching part is disposed at one end of the first limiting groove near the end cover, and the third latching part is an elastic structure, that is, the third latching part can elastically deform. In this way, when the first door panel is inserted into the first limiting groove from the end of the first limiting groove near the end cover, the third latching part elastically deforms to avoid the first door panel and avoids obstructing the first door panel. When the first door panel is installed in place, the third latching part restores its deformation to lock into the fourth end of the first door panel, thereby limiting the first door panel and preventing the first door panel from moving.

[0012] In some embodiments, the bracket may optionally include: a support portion located on one side of the first door panel, a first limiting groove disposed on the support portion, an opening provided at one end of the first limiting groove near the end cover, and the first door panel being inserted into the first limiting groove through the opening; and a limiting portion connected to the bottom of the support portion and blocking the end of the first limiting groove away from the end cover, with the third end of the first door panel supported by the limiting portion.

[0013] In this embodiment, the bracket includes a support portion and a limiting portion. The support portion is located on one side of the first door panel, and the first limiting groove is provided on the support portion. The end of the first limiting groove near the end cover is provided with an opening, and the end of the first limiting groove away from the end cover is blocked by the limiting portion. In this way, after the first door panel is inserted into the first limiting groove through the opening, the third end of the first door panel can be supported on the limiting portion, preventing the first door panel from continuing to move away from the end cover and ensuring the reliability of the installation position of the first door panel.

[0014] In some embodiments, the limiting part is optionally provided with a second limiting groove, the second limiting groove is connected to the first limiting groove, and the third end of the first door panel is disposed in the second limiting groove.

[0015] In this embodiment, the limiting part is provided with a second limiting groove, which is connected to the first limiting groove. In this way, when the third end of the first door panel is inserted into the second limiting groove, the first door panel can be limited in the front and rear directions through the second limiting groove, thereby improving the connection reliability between the first door panel and the bracket.

[0016] In some embodiments, the door assembly may optionally include a second door panel disposed on the side of at least two supports away from the housing, the second door panel being opposite to and spaced apart from the first door panel.

[0017] In this embodiment, the door assembly also includes a second door panel, which is disposed on the side of the bracket away from the housing. The second door panel is spaced apart from the first door panel, so that air insulation is formed between the second door panel and the first door panel to prevent heat from the housing from being transferred to the second door panel, thereby preventing the user from being burned when touching the door assembly.

[0018] In some embodiments, the second door panel is optionally bonded to the bracket.

[0019] In this embodiment, the second door panel is bonded to the bracket, so that the second door panel is connected to the brackets on both sides of the first door panel. On the one hand, this simplifies the installation process of the second door panel and makes the appearance of the door assembly more aesthetically pleasing. On the other hand, after the second door panel bonds at least two oppositely arranged brackets together, it also facilitates the installation of the first door panel and the bracket.

[0020] In some embodiments, the bracket may optionally include a limiting block located at one end of the bracket near the end cover and on the side of the second door panel facing the first door panel. The limiting block and the second door panel enclose a slot, and the side wall of the end cover is inserted into the slot.

[0021] In this embodiment, a limiting block is provided at one end of the bracket near the end cap. The limiting block is located on the side of the second door panel facing the first door panel, and the limiting block and the second door panel enclose a slot. The side wall of the end cap is inserted into the slot, so that the end cap is pressed against the end of the bracket, preventing the bracket from moving back and forth (e.g., along the front and back direction of the cooking appliance), thus fixing the end cap and the bracket.

[0022] In some embodiments, the door assembly may optionally include: a handle, a first through hole on the second door panel, a second through hole on the bracket, the first through hole and the second through hole being disposed opposite to each other, and the handle being connected to the bracket through the first through hole and the second through hole; and / or a door lock disposed on the bracket, wherein the door lock is locked to the cabinet when the door assembly is closed; and / or both the first door panel and the second door panel are glass door panels.

[0023] In this embodiment, the door assembly also includes a handle, which is fixed to the bracket via a first through hole on the second door panel and a second through hole on the bracket, facilitating the user to open or close the cabinet. Optionally, the door assembly also includes a door lock, which is mounted on the bracket. When the door assembly is closed, it locks the cabinet to prevent accidental opening. Optionally, both the first and second door panels are glass panels, allowing light to pass through and facilitating the user's observation of the cooking process inside the cabinet.

[0024] In some embodiments, the inner wall of the end cap is optionally provided with a limiting boss, and at least a portion of the limiting boss is located on the side of the first door panel near the housing along the thickness direction of the first door panel, and the limiting boss abuts against the first door panel.

[0025] In this embodiment, the limiting boss on the end cover is located on the side of the first door panel close to the box body along the thickness direction, and the limiting boss abuts against the first door panel, which can limit the back-and-forth shaking of the first door panel.

[0026] In some embodiments, the end cap may optionally have a recessed groove, which is located on the outer side wall of the end cap and on the side of the end cap closer to the housing along the thickness direction. The recessed groove is recessed towards the first door panel to form a limiting boss on the inner side wall of the end cap.

[0027] In this embodiment, a recessed groove is provided on the outer wall of the end cap, which is recessed towards the first door panel, thereby forming a limiting boss on the inner wall surface of the end cap, saving materials and reducing manufacturing costs.

[0028] In some embodiments, the first latching part is optionally a buckle, and the second latching part is a slot, the slot being disposed on the top wall of the end cap, and the buckle engaging with the slot.

[0029] In this embodiment, the first snap-fit ​​part is a buckle, and the second snap-fit ​​part is a slot. Through the snap-fit ​​cooperation of the buckle and the slot, the end cap and the bracket can be quickly disassembled and assembled.

[0030] In some embodiments, the top wall of the end cap is optionally provided with a groove, the groove is recessed towards the first door panel, a slot is provided on the bottom wall of the groove, a buckle passes through the slot and is engaged with the bottom wall of the groove; and / or the buckle is an elastic structure.

[0031] In this embodiment, the top wall of the end cap is provided with a groove, which is recessed towards the first door panel. A slot is provided on the bottom wall of the groove. This prevents the buckle from protruding from the top of the end cap after it extends into the slot and locks into the bottom wall of the groove, making the door assembly more aesthetically pleasing. Optionally, the buckle is an elastic structure, allowing it to deform elastically. When cleaning the door assembly, the brackets and end cap can be disassembled simply by prying the buckles on both sides of the bracket outward.

[0032] According to a second aspect of the invention, a cooking appliance is also provided, comprising: a housing; and a door assembly as described in any of the above embodiments, the door assembly being movably connected to the housing for opening or closing the housing.

[0033] The cooking appliance provided in the second aspect of the present invention, having included the door assembly proposed in any of the above embodiments, thus possesses all the beneficial effects of the door assembly.

[0056] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0057] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0058] The following reference Figures 1 to 18 This invention describes door components and cooking appliances proposed according to some embodiments of the present invention.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, according to an embodiment of the present invention, a door assembly is provided for a cooking appliance. The cooking appliance includes a housing, and the door assembly is movably connected to the housing for opening or closing the housing. The door assembly includes: at least two supports 1, which are arranged opposite to each other. Each support 1 has a first limiting groove 10 and a first engaging portion 11; a first door panel 2, disposed between the at least two supports 1, which includes a first end 20 and a second end 22 arranged opposite to each other, and a third end 24 and a fourth end 26 arranged opposite to each other. The first end 20 and the second end 22 of the first door panel 2 are respectively inserted into the first limiting groove 10 of the at least two supports 1, and the third end 24 of the first door panel 2 is limitedly engaged with the support 1; and an end cap 3, disposed at the fourth end 26 of the first door panel 2, and the end cap 3 is respectively connected to the supports 1 on both sides of the first door panel 2; wherein the end cap 3 has at least two second engaging portions 30, and the first engaging portion 11 engages with the second engaging portion 30 to make the end cap 3 detachably connected to the at least two supports 1.

[0060] The door assembly provided by this invention is used in a cooking appliance. The door assembly is movably connected to the appliance's housing, allowing the housing to be opened or closed. The door assembly includes at least two supports 1, a first door panel 2, and an end cap 3. The at least two supports 1 are arranged opposite each other, and the first door panel 2 is disposed between the at least two supports 1. The first end 20 and the second end 22 of the first door panel 2 are respectively inserted into the first limiting grooves 10 of the at least two supports 1, enabling rapid assembly of the first door panel 2 and the at least two supports 1. At the same time, the third end 24 of the first door panel 2 is limited and engaged with the support 1. The end cap 3 is disposed at the fourth end 26 of the first door panel 2, fixing the first door panel 2 and preventing it from shifting. The end cap 3 is engaged with the first engaging part 11 on at least two brackets 1 via the second engaging part 30, so that the bracket 1, the first door panel 2 and the end cap 3 are detachably connected, thereby enabling the quick disassembly and assembly of the door components. No additional tools are required when disassembling and assembling the door components, which improves the disassembly and assembly speed and the cleanliness of the door components.

[0061] Optionally, when assembling the door assembly, the first end 20 and the second end 22 of the first door panel 2 are aligned with the first limiting grooves 10 on the brackets 1 located on both sides of the first door panel 2, and the first door panel 2 is inserted into the first limiting grooves 10 to achieve quick assembly of the first door panel 2 and the first limiting grooves 10. At the same time, the third end 24 of the first door panel 2 is limited and engaged with the brackets 1 to prevent the first door panel 2 from moving. Then, the end cap 3 is engaged with the first snap-fit ​​parts 11 on the brackets 1 on both sides of the first door panel 2 to achieve assembly of the end cap 3 and the brackets 1. Correspondingly, when disassembling the door assembly, the first snap-fit ​​parts 11 and the second snap-fit ​​parts 30 between the end cap 3 and the brackets 1 are separated to separate the end cap 3 from the brackets 1. Then, the first door panel 2 is pulled out from the first limiting grooves 10 to achieve quick disassembly of the end cap 3, the brackets 1 and the first door panel 2. This allows the end cap 3, the first door panel 2 and the brackets 1 to be cleaned separately, improving the cleanability of the end cap 3, the first door panel 2 and the brackets 1.

[0062] Optionally, there are two brackets 1, located on opposite sides of the first door panel 2. The first end 20 of the first door panel 2 is inserted into the first limiting groove 10 of one bracket 1, and the second end 22 of the first door panel 2 is inserted into the first limiting groove 10 of the other bracket 1. The third end 24 of the first door panel 2 is supported by the two brackets 1, and the end cap 3 is pressed onto the fourth end 26 of the first door panel 2. The second snap-fit ​​portion 30 on the end cap 3 is respectively disposed opposite to the first snap-fit ​​portion 11 on the two brackets 1, so that the end cap 3 and the two brackets 1 are snapped together by the first snap-fit ​​portion 11 and the second snap-fit ​​portion 30.

[0063] like Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, optionally, the bracket 1 is further provided with a third snap-fit ​​part 12, which is located at one end of the first limiting groove 10 near the end cover 3, and the third snap-fit ​​part 12 is snapped into the fourth end 26 of the first door panel 2.

[0064] In this embodiment, the bracket 1 is also provided with a third snap-fit ​​part 12. The third snap-fit ​​part 12 is located at one end of the first limiting groove 10 near the end cover 3. When the first door panel 2 is installed in the first limiting groove 10, the third snap-fit ​​part 12 snaps into the fourth end 26 of the first door panel 2, so that the first door panel 2 is fixed in the first limiting groove 10, preventing the first door panel 2 from moving.

[0065] In some embodiments, the third snap-fit ​​portion 12 is optionally an elastic structure.

[0066] In this embodiment, the third latching part 12 is disposed at one end of the first limiting groove 10 near the end cover 3, and the third latching part 12 is an elastic structure, that is, the third latching part 12 can elastically deform. In this way, when the first door panel 2 is inserted into the first limiting groove 10 from the end of the first limiting groove 10 near the end cover 3, the third latching part 12 elastically deforms to avoid the first door panel 2 and avoids obstructing the first door panel 2. When the first door panel 2 is installed in place, the third latching part 12 restores its deformation to lock into the fourth end 26 of the first door panel 2, thereby limiting the first door panel 2 and preventing the first door panel 2 from moving.

[0067] It is understandable that when the first door panel 2 needs to be disassembled, after the end cover 3 is separated from the bracket 1, the third latching part 12 is pushed to deform the third latching part 12 away from the first door panel 2, thereby separating the third latching part 12 from the fourth end 26 of the first door panel 2 and realizing the disassembly of the first door panel 2.

[0068] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, the bracket 1 includes: a support portion 13 located on one side of the first door panel 2, a first limiting groove 10 disposed on the support portion 13, an opening 102 provided at one end of the first limiting groove 10 near the end cover 3, the first door panel 2 being inserted into the first limiting groove 10 through the opening 102; and a limiting portion 14 connected to the bottom of the support portion 13 and blocking the end of the first limiting groove 10 away from the end cover 3, the third end 24 of the first door panel 2 being supported by the limiting portion 14.

[0069] In this embodiment, the bracket 1 includes a support portion 13 and a limiting portion 14. The support portion 13 is located on one side of the first door panel 2. A first limiting groove 10 is provided on the support portion 13. An opening 102 is provided at one end of the first limiting groove 10 near the end cover 3. The end of the first limiting groove 10 away from the end cover 3 is blocked by the limiting portion 14. In this way, after the first door panel 2 is inserted into the first limiting groove 10 through the opening 102, the third end 24 of the first door panel 2 can be supported on the limiting portion 14, preventing the first door panel 2 from continuing to move away from the end cover 3 and ensuring the reliability of the installation position of the first door panel 2.

[0070] Optionally, the limiting portions 14 of the two opposing brackets 1 on both sides of the first door panel 2 are spaced apart to reduce material usage, manufacturing costs, and the overall weight of the door assembly. Alternatively, the limiting portions 14 of the two opposing brackets 1 on both sides of the first door panel 2 are connected, so that at least two brackets 1 are connected as one unit, further improving assembly speed and reducing assembly difficulty.

[0071] like Figure 2 and Figure 3As shown, in some embodiments, optionally, the limiting part 14 is provided with a second limiting groove 140, the second limiting groove 140 is connected to the first limiting groove 10, and the third end 24 of the first door panel 2 is provided in the second limiting groove 140.

[0072] In this embodiment, the limiting part 14 is provided with a second limiting groove 140, which is connected to the first limiting groove 10. In this way, when the third end 24 of the first door panel 2 is inserted into the second limiting groove 140, the first door panel 2 can be limited in the front and rear directions through the second limiting groove 140, thereby improving the connection reliability between the first door panel 2 and the bracket 1.

[0073] It is understandable that the second limiting groove 140 extends along the direction from the first end 20 to the second end 22 of the first door panel 2.

[0074] like Figure 2 , Figure 10 and Figure 17 As shown, in some embodiments, the door assembly may optionally include a second door panel 4, disposed on the side of at least two supports 1 away from the housing, the second door panel 4 being opposite to and spaced apart from the first door panel 2.

[0075] In this embodiment, the door assembly also includes a second door panel 4, which is disposed on the side of the bracket 1 away from the box body. The second door panel 4 is spaced apart from the first door panel 2, so that air insulation is formed between the second door panel 4 and the first door panel 2 to prevent heat from the box body from being transferred to the second door panel 4, thereby preventing the user from being burned when touching the door assembly.

[0076] In some embodiments, the second door panel 4 is optionally bonded to the bracket 1.

[0077] In this embodiment, the second door panel 4 is bonded to the bracket 1, so that the second door panel 4 is connected to the brackets 1 on both sides of the first door panel 2. On the one hand, this simplifies the installation process of the second door panel 4 and makes the appearance of the door assembly more beautiful. On the other hand, after the second door panel 4 bonds at least two oppositely arranged brackets 1 together, it also facilitates the installation of the first door panel 2 and the brackets 1.

[0078] like Figure 4 , Figure 5 , Figure 12 and Figure 13 As shown, in some embodiments, optionally, the bracket 1 is also provided with a limiting block 15. The limiting block 15 is located at one end of the bracket 1 near the end cover 3 and on the side of the second door panel 4 facing the first door panel 2. The limiting block 15 and the second door panel 4 enclose a slot 5, and the side wall of the end cover 3 is inserted into the slot 5.

[0079] In this embodiment, a limiting block 15 is provided at one end of the bracket 1 near the end cap 3. The limiting block 15 is located on the side of the second door panel 4 facing the first door panel 2, and the limiting block 15 and the second door panel 4 enclose a slot 5. The side wall of the end cap 3 is inserted into the slot 5, so that the end cap 3 is pressed against the end of the bracket 1, preventing the bracket 1 from moving back and forth (e.g., along the front and back direction of the cooking appliance), and thus fixing the end cap 3 and the bracket 1.

[0080] like Figure 2 , Figure 15 and Figure 18 As shown, in some embodiments, optionally, the door assembly further includes: a handle 6, a first through hole 40 on the second door panel 4, a second through hole 16 on the bracket 1, the first through hole 40 and the second through hole 16 being arranged opposite to each other, and the handle 6 being connected to the bracket 1 through the first through hole 40 and the second through hole 16; and / or a door lock 7, provided on the bracket 1, which locks the cabinet when the door assembly is closed; and / or both the first door panel 2 and the second door panel 4 are glass door panels.

[0081] In this embodiment, the door assembly further includes a handle 6, which is fixed to the bracket 1 via a first through hole 40 on the second door panel 4 and a second through hole 16 on the bracket 1, facilitating the user to open or close the cabinet. Optionally, the door assembly also includes a door lock 7, which is mounted on the bracket 1. When the door assembly is closed, it locks the cabinet to prevent accidental opening. Optionally, both the first door panel 2 and the second door panel 4 are glass panels, allowing light to pass through and facilitating the user's observation of the cooking process inside the cabinet.

[0082] like Figure 2 , Figure 12 and Figure 14 As shown, in some embodiments, optionally, the inner sidewall of the end cover 3 is provided with a limiting boss 32. Along the thickness direction of the first door panel 2, at least a portion of the limiting boss 32 is located on the side of the first door panel 2 near the box body, and the limiting boss 32 abuts against the first door panel 2.

[0083] In this embodiment, the limiting boss 32 on the end cover 3 is located on the side of the first door panel 2 close to the box body along the thickness direction, and the limiting boss 32 abuts against the first door panel 2, which can limit the back and forth swaying of the first door panel 2.

[0084] like Figure 2 , Figure 11 , Figure 12 and Figure 14 In some embodiments, the end cover 3 is optionally provided with a recessed groove 36, which is provided on the outer side wall of the end cover 3 and located on the side of the end cover 3 close to the box body along the thickness direction. The recessed groove 36 is recessed in the direction close to the first door panel 2 to form a limiting protrusion 32 on the inner side wall of the end cover 3.

[0085] In this embodiment, a recessed groove 36 is provided on the outer side wall of the end cover 3. The recessed groove 36 is recessed towards the first door panel 2, thereby forming a limiting boss 32 on the inner wall surface of the end cover 3, which saves materials and reduces manufacturing costs.

[0086] Along the thickness direction of the first door panel 2, the end cover 3 is provided with a limiting boss 32 on the side near the box body. The limiting boss 32 is recessed in the direction close to the first door panel 2 and abuts against the first door panel 2.

[0087] In this embodiment, along the thickness direction of the first door panel 2, the end cover 3 is provided with a limiting boss 32 on the side near the box body. The limiting boss 32 is recessed in the direction close to the first door panel 2, so that the outer wall of the limiting boss 32 abuts against the first door panel 2, which can limit the back-and-forth shaking of the first door panel 2.

[0088] It should be noted that the outer wall of the limiting boss 32 is the wall surface of the limiting boss 32 facing the first door panel 2.

[0089] Optionally, if the bracket 1 is provided with a third latching part 12, the third latching part 12 is located on the side of the first limiting groove 10 near the second door panel 4.

[0090] like Figure 15 and Figure 16 As shown, in some embodiments, optionally, the first snap-fit ​​part 11 is a snap buckle 110, and the second snap-fit ​​part 30 is a snap-fit ​​groove 300. The snap-fit ​​groove 300 is provided on the top wall of the end cover 3, and the snap buckle 110 is snapped into the snap-fit ​​groove 300.

[0091] In this embodiment, the first snap-fit ​​part 11 is a snap-fit ​​110, and the second snap-fit ​​part 30 is a snap-fit ​​groove 300. Through the snap-fit ​​cooperation of the snap-fit ​​110 and the snap-fit ​​groove 300, the end cover 3 and the bracket 1 can be quickly disassembled and assembled.

[0092] In some embodiments, the top wall of the end cap 3 is optionally provided with a groove 34, the groove 34 is recessed in the direction close to the first door panel 2, the slot 300 is provided on the bottom wall of the groove 34, the buckle 110 passes through the slot 300 and is engaged with the bottom wall of the groove 34; and / or the buckle 110 is an elastic structure.

[0093] In this embodiment, the top wall of the end cap 3 is provided with a groove 34, which is recessed towards the first door panel 2. A slot 300 is provided on the bottom wall of the groove 34. In this way, after the buckle 110 extends into the slot 300 and is locked in the bottom wall of the groove 34, the buckle 110 is prevented from protruding from the top of the end cap 3, making the door assembly more aesthetically pleasing. Optionally, the buckle 110 is an elastic structure, allowing it to deform elastically. When cleaning the door assembly, the buckles 110 on both sides of the bracket 1 can be pried outward to disassemble the bracket 1 and the end cap 3.

[0094] According to some embodiments of this application, this application proposes a quick-release structure for a freestanding large oven, wherein the door assembly consists of an outer door glass (e.g., a second door panel 4), an inner door glass (e.g., a first door panel 2), a door handle (e.g., a handle 6), a top cover (e.g., an end cover 3), a left bracket (e.g., a bracket 1), a right bracket (e.g., a bracket 1), and a door lock 7.

[0095] like Figure 2 , Figure 3 and Figure 4 As shown, the left and right brackets each have two latching structures: an inner glass latch (e.g., the third latching part 12) and an upper cover latch (e.g., the first latching part 11), a door handle fixing hole (e.g., the second through hole 16), and an inner glass limiting groove (e.g., the first limiting groove 10 and the second limiting groove 140). The left bracket also has two additional fixing holes for fixing the door lock 7.

[0096] like Figure 6 and Figure 7 As shown, the top of the cover has three door inner glass snaps (e.g., limiting protrusions 32) and snap slots on both sides of the front (e.g., second snap-fit ​​parts 30).

[0097] The specific installation and operation mode of the door assembly are as follows: First, the left and right brackets are glued together with the outer glass of the door. Then, the door handle and door lock 7 are fixed to the bracket 1 through the fixing holes on the bracket 1. Next, the inner glass is inserted into the bottom of the bracket 1 from the top along the limiting grooves (e.g., the first limiting groove 10) of the left and right brackets. After the inner glass is inserted into the bottom, the bracket buckle (e.g., the third snap-fit ​​part 12) pops up, clamping the inner glass between the left and right brackets. When the oven is working, the limiting grooves of the left and right brackets clamp the inner glass in the middle, restricting the deformation of the glass, thereby ensuring the sealing of the oven door. Finally, as Figure 12 and Figure 13As shown, the top cover is inserted along the gap (e.g., slot 5) between the outer glass, left bracket, and right bracket. One side of the top cover is pressed under the bracket 1 to prevent the bracket 1 from moving back and forth. At the same time, the inner glass is pressed tightly by the top cover's snap fastener (e.g., limiting boss 32). The front of the top cover is pressed into the buckle 110 (e.g., first snap-fit ​​part 11) of the bracket 1, and the top cover is fixed by the buckle 110. This achieves rapid installation of the furnace door.

[0098] When cleaning the door components, simply pry the buckles 110 of the left and right brackets on both sides outwards, and pull the top cover upwards. After removing the top cover, remove the inner glass, thus achieving quick disassembly of the furnace door. Then clean the inner glass and the inside of the furnace door. After cleaning, reinstall the inner glass and top cover according to the installation steps above, and you can repeat the installation and disassembly process.
