Description

Technical Field

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

[0002] In traditional cooking appliances with steaming and baking functions, the front panel of the door is often made of tempered glass and fixed with adhesive, serving as the main load-bearing component to support the installation of other parts. This structure makes the front panel irreplaceable. When the appliance is embedded in a cabinet, the front panel looks significantly different from the surrounding cabinet doors, making it impossible to achieve a unified kitchen design style and personalization. At the same time, the lack of effective heat insulation design poses a risk of heat transfer and burns to users who touch it. Utility Model Content

[0003] Therefore, it is necessary to provide a door structure and cooking device to address the above problems. This door structure allows for easy replacement of the front panel, improving aesthetics.

[0004] This utility model provides a door structure, including: a panel assembly, including a panel and a positioning member, the positioning member being detachably disposed on one side of the panel; a door panel assembly, including a mounting bracket, the mounting bracket including a positioning part that can cooperate with the positioning member, the mounting bracket having a plurality of first mounting holes, the mounting bracket being detachably connected to the side of the panel with the positioning member at the first mounting holes by fasteners; and a heat insulation assembly, detachably disposed on the side of the mounting bracket opposite to the panel.

[0005] This design allows the positioning component and the positioning part to work together to pre-position the panel, reducing positional deviations during installation. The fasteners in the first mounting hole then complete the final fixation, ensuring accurate and reliable panel installation. The mounting bracket is connected to the panel through the first mounting hole and fasteners. This detachable connection method replaces the traditional adhesive fixation, allowing the panel to be easily replaced according to user needs. The heat insulation component is detachably mounted on the side of the mounting bracket away from the panel. This effectively blocks heat from the inside of the cooking equipment from being transferred to the outside of the door, reducing the surface temperature of the door and preventing users from being burned. It also facilitates disassembly for maintenance or replacement of internal components of the panel or door structure.

[0006] In one embodiment, the positioning element is a positioning bracket, and the positioning part is a positioning groove that can engage with the positioning bracket.

[0007] This design allows the positioning bracket and positioning groove to interlock, providing stable positioning support for the panel and door components. The interlocking method is simple to operate, requiring no tools for initial positioning, followed by securing with fasteners at the first mounting hole to ensure a firm connection. This structure makes panel replacement more convenient; simply disengage the interlocking mechanism and fasteners to remove the panel, and install it by reversing the process. This improves the efficiency of panel replacement for users. Simultaneously, the interlocking mechanism can withstand certain lateral and longitudinal forces, ensuring the stability of the door structure during use.

[0008] In one embodiment, the door structure further includes two sets of hinge fixing components, which are detachably disposed on both sides of the mounting bracket and extend along the height direction of the mounting bracket; the heat insulation component is located between the two sets of hinge fixing components.

[0009] This design, with two sets of hinge fixing components extending along the height of the mounting bracket, not only hinges the door structure to the cabinet of the cooking equipment, allowing the door to rotate around the hinges, but also limits the movement of the heat insulation component, fixing it between the two sets of hinge fixing components to prevent lateral movement within the door structure and ensuring its positional stability. Furthermore, the detachable connection between the hinge fixing components and the mounting bracket facilitates the overall installation and disassembly of the door structure, allowing for quick disassembly and replacement of the hinge fixing components during maintenance.

[0010] In one embodiment, the thermal insulation assembly includes a first glass assembly and a second glass assembly stacked on the side of the first glass assembly near the mounting bracket.

[0011] In this configuration, the first and second glass components are stacked, forming an air layer between them. This air layer provides excellent heat and sound insulation, effectively preventing heat from the inside of the cooking appliance from transferring to the outside of the door, while also reducing noise transmission during operation. Furthermore, the double-glazed design enhances the door's strength and safety, preventing the glass from breaking due to accidental impacts.

[0012] In one embodiment, the first glass assembly includes a first glass and a first bracket and a second bracket respectively disposed on the top edge and bottom edge of the first glass, the first bracket and the second bracket both extending along the length direction of the first glass; the first bracket is detachably connected to the door panel assembly or the hinge fixing assembly, and the second bracket is detachably connected to the door panel assembly or the hinge fixing assembly.

[0013] With this configuration, the first and second brackets are located at the top and bottom of the first glass panel, respectively, extending along its length to provide stable support. During installation, the first bracket is first connected to the door panel assembly or hinge fixing assembly, and then the second bracket is also connected to the door panel assembly or hinge fixing assembly, forming a stable frame structure that secures the first glass panel to the door. This structure not only enhances the overall strength of the first glass assembly, preventing breakage due to external forces during use, but also facilitates the installation and disassembly of the first glass assembly, improving the convenience of maintenance and replacement, and extending the service life of the door.

[0014] In one embodiment, the door panel assembly further includes a top bracket detachably disposed on top of the mounting bracket and extending along the length of the mounting bracket, wherein the first bracket is detachably connected to the top bracket.

[0015] This configuration, with the top bracket detachably mounted on the mounting bracket, increases the structural strength of the door panel assembly and provides a mounting support point for the first bracket. The detachable connection between the first bracket and the top bracket secures the top of the first glass assembly. Combined with the connection between the second bracket and the door panel assembly or hinge fixing assembly, this makes the first glass assembly more stable within the door structure. The top bracket can also be used to install other components, such as lighting components or camera components, expanding the functionality of the door panel assembly.

[0016] In one embodiment, the top and bottom edges of the second glass assembly abut against the top support and the second support, respectively.

[0017] This configuration ensures that the top edge of the second glass assembly abuts against the top support, and the bottom edge abuts against the second support, thus supporting the second glass assembly between the top and second supports and achieving both positioning and support. The top and second supports provide a stable support surface for the second glass assembly, preventing it from moving up and down or swaying within the door structure and ensuring its positional stability. Simultaneously, this structure maintains a uniform air gap between the second and first glass assemblies when they are stacked, guaranteeing effective heat and sound insulation.

[0018] In one embodiment, the second glass assembly includes a second glass and two sealing strips, which are respectively disposed between the two sides of the second glass and the corresponding hinge fixing assembly, and extend along the height direction of the second glass.

[0019] This design allows the sealing strip to fill the gap between the second glass and the hinge fixing components, effectively preventing the exchange of heat, gas, and impurities between the inside and outside of the door. The flexibility and elasticity of the sealing strip allow it to adapt to minor deformations and displacements of the door during opening and closing, maintaining excellent sealing performance. Simultaneously, the sealing strip extends along the height of the second glass, ensuring a uniform seal across the entire height range, improving the door's heat and sound insulation, and providing users with a more comfortable and efficient cooking environment.

[0020] In one embodiment, the sealing strip includes a hollow portion and an extension portion. The two ends of the hollow portion abut against the side of the second glass and the corresponding hinge fixing assembly, respectively, and the two ends of the extension portion abut against the second glass and the first glass assembly, respectively.

[0021] This design allows the two ends of the hollow section to abut against the sides of the second glass and the corresponding hinge fixing components, respectively. The elastic deformation of the hollow section absorbs the impact force between the hinge fixing components and the second glass component, providing a seal while reducing vibration and noise. The two ends of the extension section abut against both the second and first glass components, filling the gap between them and preventing heat and moisture leakage. The combined design of the hollow section and the extension section gives the sealing strip both buffering and sealing functions, improving the performance of the door structure and ensuring heat insulation, sound insulation, and structural stability. Furthermore, the two ends of the extension section abut against both the second and first glass components, limiting their relative position and ensuring stability. Simultaneously, the two ends of the hollow section abut against the sides of the second glass and the corresponding hinge fixing components, restricting the lateral displacement of the second glass.

[0022] In one embodiment, the door structure further includes a lighting assembly, the two ends of which abut against the mounting bracket and the second glass assembly, respectively.

[0023] With this setup, the lighting component can provide illumination to the inside of the door, making it easier for users to observe the food inside the oven. The two ends of the lighting component abut against the mounting bracket and the second glass component, respectively, ensuring that the lighting component and the second glass component are stably installed in the door structure and are not easily shaken.

[0024] This utility model also provides a cooking device, including the above-mentioned door structure.

[0025] With this design, the cooking appliance, through its replaceable front panel structure, allows for quick replacement and customization of the front panel, satisfying users' diverse aesthetic needs and pursuit of a unified kitchen style. Simultaneously, the design of the insulation components, sealing strips, and lighting components within the door structure improves the appliance's insulation, sealing performance, and safety, while reducing energy consumption and maintenance costs.

[0037] In traditional cooking appliances with steaming and baking functions, the front panel of the door is often made of tempered glass and fixed with adhesive, serving as the main load-bearing component to support the installation of other parts. This structure makes the front panel irreplaceable. When the appliance is embedded in a cabinet, the front panel looks significantly different from the surrounding cabinet doors, making it impossible to achieve a unified kitchen design style and personalization. At the same time, the lack of effective heat insulation design poses a risk of heat transfer and burns to users who touch it.

[0038] To solve the above problems, such as Figure 1 As shown, this application provides a door structure and cooking equipment. The door structure allows for easy replacement of the front panel, improving aesthetics.

[0039] like Figure 1 As shown, the positive Z-axis direction is the top of the door structure, the negative Z-axis direction is the bottom of the door structure, and the two sides of the door structure extend along the Y-axis direction.

[0040] like Figure 1 As shown, this application first provides a door structure, including a panel assembly 1, including a panel 11 and a positioning member 12, the positioning member 12 being detachably disposed on one side of the panel 11; the door panel assembly 2 includes a mounting bracket 21, the mounting bracket 21 including a positioning part 211 that can cooperate with the positioning member 12, the mounting bracket 21 having a plurality of first mounting holes 212, the mounting bracket 21 being detachably connected to the side of the panel 11 with the positioning member 12 at the first mounting holes 212 by fasteners such as screws and bolts; the heat insulation component 3 is detachably disposed on the side of the mounting bracket 21 away from the panel 11.

[0041] With this configuration, the mechanical cooperation between the positioning component 12 and the positioning part 211 achieves the pre-positioning of the panel 11, reducing positional deviations during installation. The final fixation is then completed through the fasteners in the first mounting hole 212, ensuring that the panel 11 is installed accurately and reliably. The mounting bracket 21 is connected to the panel 11 through the first mounting hole 212 and the fasteners. This detachable connection method replaces the traditional adhesive fixation, allowing the panel 11 to be easily replaced according to user needs. The heat insulation component 3 is detachably mounted on the side of the mounting bracket 21 away from the panel 11. It can effectively block the heat inside the cooking equipment from being transferred to the outside of the door, reduce the surface temperature of the door, and prevent users from being burned by touching it. It also facilitates the maintenance or replacement of the panel 11 or internal components of the door structure after disassembly.

[0042] Among them, panel 11 can be a wooden door panel that matches the cabinets, so as to achieve an integrated style of kitchen design.

[0043] Specifically, the multiple first mounting holes 212 are designed to be arranged at intervals along the circumference of the mounting bracket 21 to ensure a reliable connection between the panel 11 and the mounting bracket 21.

[0044] like Figures 1 to 2 As shown, in one embodiment, the positioning element 12 is a positioning bracket, and the positioning part 211 is a positioning groove that can engage with the positioning bracket. This configuration allows the positioning bracket and the positioning groove to engage, providing stable positioning support for the panel assembly 1 and the door panel assembly 2. The engagement method is simple to operate, requiring no tools for initial positioning, followed by fixation using fasteners at the first mounting hole 212 to ensure a secure connection. This structure makes replacing the panel 11 more convenient; simply disengaging the engagement and fastener connection allows for panel 11 removal, and installation is performed in reverse, improving the efficiency of panel 11 replacement. Simultaneously, the engagement can withstand certain lateral and longitudinal forces, ensuring the stability of the door structure during use.

[0045] Specifically, two sets of positioning components 12 and corresponding positioning parts 211 can be designed and symmetrically arranged along the extension direction of both sides of the door structure. When the panel 11 needs to be installed, the center line of the panel 11 in the Y-axis direction can be found by measuring tape. Then, the fixing fixture 200 of the positioning component 12 is precisely attached to the center line on one side, and the other side is attached to the bottom edge of the panel 11 by the limiting claw 201. At this time, the position of at least one small hole on the fixing fixture 200 is the fixing hole position of the positioning component 12 of the panel 11. Then, two positioning components 12 are fixed on the panel 11.

[0046] In another embodiment, the number of positioning elements 12 can be one, three, four or more, and the positioning parts 211 are arranged in a one-to-one correspondence with the positioning elements 12. The number and arrangement of the positioning elements 12 and the corresponding positioning parts 211 can be adjusted according to actual needs. This embodiment of the present invention does not impose specific limitations here.

[0047] In another embodiment, the positioning element 12 can be a positioning pin, and the positioning part 211 is a corresponding positioning hole. Positioning is achieved by inserting the positioning pin into the positioning hole.

[0048] In another embodiment, the positioning member 12 can be a threaded positioning post, and the positioning part 211 is a threaded hole that mates with it. The detachable connection between the panel assembly 1 and the door panel assembly 2 is achieved through the threaded connection.

[0049] In another embodiment, the positioning member 12 may be a magnetic structure, the positioning part 211 is a corresponding magnetic block, and the positioning member 12 and the positioning part 211 are positioned by magnetic force cooperation.

[0050] like Figure 1 As shown, in one embodiment, the door structure further includes two sets of hinge fixing components 5. These two sets of hinge fixing components 5 are detachably mounted on both sides of the mounting bracket 21 and extend along the height direction of the mounting bracket 21. The heat insulation component 3 is positioned between the two sets of hinge fixing components 5. This arrangement, with the two sets of hinge fixing components 5 extending along the height direction of the mounting bracket 21, not only hinges the door structure to the cabinet of the cooking equipment, allowing the door to rotate around the hinges, but also limits the heat insulation component 3, fixing it between the two sets of hinge fixing components 5 and preventing it from moving left or right within the door structure, ensuring the stability of its position. Simultaneously, the detachable connection between the hinge fixing components 5 and the mounting bracket 21 facilitates the overall installation and disassembly of the door structure. When maintenance or replacement of the hinge fixing components 5 is required, they can be quickly disassembled for operation.

[0051] The hinge fixing component 5 can be connected to the mounting bracket 21 by fasteners such as screws.

[0052] In another embodiment, the door structure may employ three or more sets of hinge fixing components 5 to enhance door stability, especially for larger and heavier doors.

[0053] like Figure 1 As shown, in one embodiment, the door panel assembly 2 further includes a top bracket 22, which is detachably disposed on top of the mounting bracket 21 and extends along the length of the mounting bracket 21.

[0054] The top bracket 22 can be nested with the mounting bracket 21 and the hinge fixing component 5, and is fixed to the two sets of hinge fixing components 5 by two screws respectively, thus improving the overall strength of the door structure and the precision of the assembly.

[0055] like Figure 1 As shown, in one embodiment, the heat insulation component 3 includes a first glass component 31 and a second glass component 32 stacked on the side of the first glass component 31 near the mounting bracket 21. This arrangement, with the first glass component 31 and the second glass component 32 stacked, forms an air layer between them. This air layer provides good heat and sound insulation, effectively preventing heat transfer from the inside of the cooking equipment to the outside of the door, while also reducing noise transmission during operation. Simultaneously, the double-glazed design can improve the strength and safety of the door to a certain extent, preventing the glass from breaking due to accidental impact.

[0056] In another embodiment, the heat insulation component 3 may include a three-layer glass component, stacked to form two air layers, further enhancing the heat insulation and sound insulation effects.

[0057] In another embodiment, the heat insulation component 3 can also be a layer of glass, provided that strength is guaranteed.

[0058] like Figure 1As shown, in one embodiment, the first glass assembly 31 includes a first glass 313 and a first bracket 311 and a second bracket 312 respectively disposed on the top and bottom edges of the first glass 313. Both the first bracket 311 and the second bracket 312 extend along the length of the first glass 313. The first bracket 311 is detachably connected to the door panel assembly 2 or the hinge fixing assembly 5, and the second bracket 312 is also detachably connected to the door panel assembly 2 or the hinge fixing assembly 5. With this configuration, the first bracket 311 and the second bracket 312 are located at the top and bottom of the first glass 313, respectively, extending along the length of the first glass 313, providing stable support for the first glass 313. During installation, the first bracket 311 is first connected to the door panel assembly 2 or the hinge fixing assembly 5, and then the second bracket 312 is also connected to the door panel assembly 2 or the hinge fixing assembly 5, forming a stable frame structure that secures the first glass 313 to the door. This structure not only enhances the overall strength of the first glass assembly 31, preventing the glass from breaking due to external forces during use, but also facilitates the installation and disassembly of the first glass assembly 31, improving the convenience of maintenance and replacement, and extending the service life of the door.

[0059] In one embodiment, the first bracket 311 and the second bracket 312 can be fixed to the first glass 313 by adhesive.

[0060] In another embodiment, the first bracket 311 and the second bracket 312 can be fixed to the first glass 313 by means of snap-fit ​​or other methods.

[0061] In one embodiment, the two ends of the second bracket 312 are respectively connected to the two hinge fixing components 5 by screws. In another embodiment, the two ends of the second bracket 312 can be connected to the two hinge fixing components 5 by means of adhesive snap-fit ​​or other methods.

[0062] like Figure 1 As shown, in one embodiment, the first bracket 311 is detachably connected to the top bracket 22. This arrangement allows the top bracket 22 to be detachably mounted on the mounting bracket 21, increasing the structural strength of the door panel assembly 2 and providing a mounting support point for the first bracket 311. The detachable connection between the first bracket 311 and the top bracket 22 secures the top of the first glass assembly 31. Combined with the connection of the second bracket 312 to the door panel assembly 2 or the hinge fixing assembly 5, this makes the first glass assembly 31 more stable within the door structure. The top bracket 22 can also be used to mount other components, such as the lighting assembly 4 or the camera assembly, expanding the functionality of the door panel assembly 2.

[0063] The top bracket 22 can be connected to the mounting bracket 21 by screws. The mounting bracket 21 has a threaded hole at its top, and the top bracket 22 has a through hole at a corresponding position. The screw passes through the through hole and is screwed into the threaded hole to achieve the connection. Specifically, the top bracket 22 can be designed to be made of plastic.

[0064] In another embodiment, the top bracket 22 can be designed as an adjustable structure, for example, by providing multiple mounting holes on the top bracket 22, and by selecting different holes to connect with the mounting bracket 21, the position of the top bracket 22 can be adjusted to accommodate the first glass assembly 31 with different thicknesses and sizes.

[0065] In another embodiment, the first bracket 311 can be connected to the mounting bracket 21 or the top bracket 22 by screws.

[0066] In another embodiment, the first bracket 311 and the second bracket 312 can be designed as an adjustable structure. For example, multiple mounting holes are provided on the first bracket 311 and the second bracket 312. By selecting different holes to connect with the door panel assembly 2 or the hinge fixing assembly 5, the position of the first bracket 311 and the second bracket 312 can be adjusted to adapt to different sizes of the first glass 313 or different installation requirements.

[0067] like Figure 1 As shown, in one embodiment, the top and bottom edges of the second glass assembly 32 abut against the top support 22 and the second support 312, respectively. This arrangement, with the top edge of the second glass assembly 32 abutting against the top support 22 and the bottom edge abutting against the second support 312, supports the second glass assembly 32 between the top support 22 and the second support 312, achieving positioning and support for the second glass assembly 32. The top support 22 and the second support 312 provide a stable support surface for the second glass assembly 32, preventing it from moving up and down or swaying within the door structure and ensuring its positional stability. Simultaneously, this structure ensures that when the second glass assembly 32 and the first glass assembly 31 are stacked, the air layer between them remains uniform, guaranteeing heat insulation and sound insulation effects.

[0068] like Figure 1As shown, in one embodiment, the second glass assembly 32 includes a second glass 321 and two sealing strips 33. The two sealing strips 33 are respectively disposed between the two sides of the second glass 321 and the corresponding hinge fixing assembly 5, and extend along the height direction of the second glass 321. This arrangement fills the gap between the second glass 321 and the hinge fixing assembly 5, effectively preventing the exchange of heat, gas, and impurities between the inside and outside of the door. The flexibility and elasticity of the sealing strips 33 allow them to adapt to the slight deformation and displacement of the door during opening and closing, maintaining good sealing performance. Simultaneously, the sealing strips 33 extend along the height direction of the second glass 321, ensuring a uniform sealing effect throughout the entire height range, improving the heat insulation and sound insulation of the door, and providing users with a more comfortable and efficient cooking environment.

[0069] like Figure 1 and Figure 4 As shown, in one embodiment, the sealing strip 33 includes a hollow portion 331 and an extension portion 332. The two ends of the hollow portion 331 abut against the side of the second glass 321 and the corresponding hinge fixing component 5, respectively. The two ends of the extension portion 332 abut against the second glass 321 and the first glass component 31, respectively. With this configuration, the two ends of the hollow portion 331 abut against the side of the second glass 321 and the corresponding hinge fixing component 5. The elastic deformation of the hollow portion 331 absorbs the impact force between the hinge fixing component 5 and the second glass component 32, sealing while reducing vibration and noise. Furthermore, the hollow portion 331 has an interference fit of approximately 0.3 mm, ensuring uniform force distribution on the second glass 321 in the lateral direction, ensuring centered fixation. The two ends of the extension portion 332 abut against the second glass 321 and the first glass component 31, respectively, filling the gap between the hinge fixing component 5 and the first glass component 31, thus providing a seal and preventing heat and moisture leakage. The combined design of the hollow section 331 and the extension section 332 enables the sealing strip 33 to simultaneously provide buffering and sealing functions, improving the performance of the door structure and ensuring heat insulation, sound insulation, and structural stability. Furthermore, the two ends of the extension section 332 abut against the second glass 321 and the first glass assembly 31, respectively, limiting their relative positions and ensuring stability. Simultaneously, the two ends of the hollow section 331 abut against the sides of the second glass 321 and the corresponding hinge fixing assembly 5, respectively, restricting the lateral displacement of the second glass 321.

[0070] Specifically, the hollow portion 331 has an elliptical cavity, which has good elastic deformation capability and can accommodate a large displacement. When relative movement occurs between the hinge fixing assembly 5 and the second glass assembly 32, the hollow portion 331 absorbs vibration energy through compression or stretching. The extension portion 332 is flat and perpendicularly connected to the hollow portion 331. The flat extension portion 332 can closely fit the surfaces of the second glass 321 and the first glass assembly 31, improving the sealing effect.

[0071] In another embodiment, the cavity shape of the hollow portion 331 can be adjusted according to design requirements.

[0072] like Figure 3 As shown, in one embodiment, the door structure further includes a lighting component 4, with both ends of the lighting component 4 abutting against the mounting bracket 21 and the second glass component 32, respectively. This arrangement allows the lighting component 4 to provide illumination to the interior of the door, facilitating user observation of the food inside the oven. The abutments of both ends of the lighting component 4 against the mounting bracket 21 and the second glass component 32 ensure stable installation of the lighting component 4 and the second glass component 32 within the door structure, preventing them from easily shaking.

[0073] The number and position of the lighting components 4 can be adjusted according to actual needs. For example, two sets of lighting components 4 extend along the Z-axis and are respectively set on both sides of the door structure. Specifically, one end of the lighting component 4 is bonded to the second glass component 32, and the other end abuts against the mounting bracket 21.

[0074] In the door structure provided by this utility model, the sides of the second glass 321 abut against the hollow part 331 and the corresponding hinge fixing component 5, thereby restricting the displacement of the second glass 321 in the left and right directions; the top edge of the second glass 321 abuts against the top bracket 22, and the bottom edge abuts against the second bracket 312, thereby restricting the displacement of the second glass 321 in the up and down directions; the two ends of the lighting component 4 abut against the mounting bracket 21 and the second glass 321, and the two ends of the extension 332 abut against the second glass 321 and the first glass component 31, thereby restricting the displacement of the second glass 321 in the front and back directions; with this arrangement, reliable positioning of the second glass 321 in all directions is achieved.

[0075] like Figure 1As shown, in one embodiment, the first glass assembly 31 further includes a water-retaining strip 314, which is disposed at the bottom edge of the first glass assembly 31 and extends along the width direction of the first glass 313. This arrangement allows the water-retaining strip 314 to effectively intercept condensation or steam droplets flowing down the glass surface during cooking, preventing liquid from seeping into the door body and contacting the camera assembly or heat dissipation assembly, thus avoiding problems such as short circuits and component corrosion caused by liquid erosion. Simultaneously, the water-retaining strip 314 can guide liquid to drip along the glass edge to the outside of the enclosure, reducing water accumulation inside the door. Combined with the detachable glass assembly design, it facilitates user cleaning of oil or scale adhering to the surface of the water-retaining strip 314, improving the waterproof reliability and maintenance convenience of the equipment.

[0076] This utility model also provides a cooking device including the aforementioned door structure. With this configuration, the cooking device, through the use of the replaceable panel 11 door structure, enables quick replacement and personalized customization of the panel 11, satisfying users' diverse needs for the appearance of kitchen appliances and their pursuit of an integrated kitchen style. Simultaneously, the design of the heat insulation component 3, sealing strip 33, and lighting component 4 in the door structure improves the heat insulation performance, sealing performance, and safety of the cooking device, while reducing energy consumption and maintenance costs.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
