[0039] Example 1

[0040] In the prior art, the welding position of the stainless steel cover plate 22 is located on the surface of the side close to the cooking cavity. The cooking cavity will generate water vapor and condensation. The welding position will rust due to long-term contact with condensation.

[0041] To address the aforementioned technical problems, the applicant proposes a door component, such as... Figures 1-9 As shown, the door assembly is used in a cooking device, which includes a cooking cavity with an opening, that is, the cooking cavity has an opening to facilitate the taking and placing of items.

[0042] The gate assembly includes:

[0043] Door frame 1, the door frame 1 is used to fix door assembly 2, and the door frame 1 is disposed on the side of the door assembly 2 away from the cooking cavity;

[0044] Door assembly 2, which includes a door body 21 and a cover plate 22, wherein the cover plate 22 is welded to the door body 21 on the side near the cooking cavity;

[0045] A welding groove 214 is provided on the door body 21; the cover plate 22 is made of stainless steel and a welding pin 224 is provided on the cover plate 22, the welding pin 224 being embedded inside the welding groove 214; a cover plate 3 and a sealing structure 4 are provided on the side of the welding groove 214 near the cooking cavity.

[0046] In this embodiment, a door assembly is provided with welding pins 224 embedded inside a welding groove 214. A shield 3 and a sealing structure 4 are provided on the side of the welding groove 214 near the cooking cavity. The shield 3 and the sealing structure 4 form a multi-layer protective barrier, which effectively prevents condensation or moisture from contacting the welding position. This fundamentally solves the problem of rusting at the welding position due to long-term contact with condensation, and improves the durability and reliability of the door assembly.

[0047] As a preferred example of this utility model, such as Figure 3 As shown, the sealing structure 4 is interference-fitted between the cover plate 22 and the shield plate 3.

[0048] This design improves the sealing between the cover plate 22 and the shielding plate 3, further preventing the welding pins 224 from coming into contact with condensate or moisture, and effectively solving the problem of rust at the welding position.

[0049] As a preferred example of this utility model, a second protruding edge 222 is provided on the cover plate 22, and the second protruding edge 222 is embedded inside the welding groove 214; the welding pin 224 is provided on the second protruding edge 222.

[0050] The design of the second protruding edge 222 embedded in the welding groove 214 provides precise positioning for welding the cover plate 22 to the door body 21. During the welding process, the second protruding edge 222 and the welding groove 214 cooperate with each other to ensure that the cover plate 22 is accurately installed in the predetermined position of the door body 21, avoiding offset and misalignment during welding, and making the connection between the welding pin 224 and the welding groove 214 more precise. This ensures the stability and reliability of the welding, improves the welding quality, and reduces the occurrence of welding defects.

[0051] As a preferred example of this utility model, such as Figure 7 As shown, the welding pins 224 are configured in multiple ways, and the multiple welding pins 224 are evenly arranged on the second protruding edge 222.

[0052] This design increases the contact area for welding. A larger welding area means that a stronger weld can be formed during welding, making the connection between the cover plate 22 and the door body 21 tighter. It can withstand greater external forces and vibrations, and is less likely to loosen or fall off, thus improving the overall structural stability of the door assembly.

[0053] As a preferred example of this utility model, a reinforcing protrusion 211 and a first protruding edge 212 are provided on the door body 21. The reinforcing protrusion 211 and the first protruding edge 212 extend toward the side closer to the cover plate 22. The welding groove 214 is formed between the reinforcing protrusion 211 and the first protruding edge 212. An mounting protrusion 221 is provided on the cover plate 22. The mounting protrusion 221 and the second protruding edge 222 extend toward the side closer to the door body 21. A receiving groove 223 is formed between the mounting protrusion 221 and the second protruding edge 222. The receiving groove 223 cooperates with the reinforcing protrusion 211.

[0054] This design allows for precise welding positioning, with the reinforcing protrusion 211 engaging with the receiving groove 223. This design provides precise positioning for the cover plate 22 and the door body 21 during the welding process. When installing the cover plate 22, simply align the receiving groove 223 with the reinforcing protrusion 211 and insert it. This quickly and accurately determines the position of the cover plate 22 on the door body 21, ensuring accurate welding positioning, making the welding operation more standardized and stable, effectively reducing welding deviations, improving welding quality, and lowering the welding defect rate.

[0055] As a preferred example of this utility model, such as Figure 9 As shown, a first flange 213 is provided on the first protruding edge 212, and the first flange 213 extends toward the center of the door body 21.

[0056] The first flange 213 not only further prevents the second convex edge 222 from coming into contact with condensation or moisture, solving the problem of rust at the welding position, but also enhances the structural strength of the door body 21 from different directions, improving the overall stability of the door assembly.

[0057] As a preferred example of this utility model, such as Figure 9 As shown, a second flange 215 is provided on the first flange 213, and the second flange 215 extends toward the side away from the cooking cavity.

[0058] The second flange 215 not only further prevents the second convex edge 222 from coming into contact with condensation or moisture, solving the problem of rust at the welding position, but also enhances the structural strength of the door body 21 from different directions, improving the overall stability of the door assembly.

[0059] As a preferred example of this utility model, such as Figure 3 As shown, one side of the cover plate 3 is engaged with the door frame 1, and the other side of the cover plate 3 is engaged with the sealing structure 4.

[0062] This arrangement ensures a tight connection between the baffle 3 and the sealing structure 4, further improving the sealing effect and effectively preventing the intrusion of condensate or moisture.

[0063] As a preferred example of this utility model, such as Figure 4 As shown, a third locking block 32 is provided on the cover plate 3, and a fourth locking block 42 is provided on the sealing structure 4. The fourth locking block 42 cooperates with the third locking block 32 to engage.

[0064] This arrangement ensures a tight connection between the baffle 3 and the sealing structure 4, further improving the sealing effect and effectively preventing the intrusion of condensate or moisture.

[0065] As a preferred example of this utility model, such as Figure 4 As shown, the third locking block 32 is disposed on the first locking block 31, and the third locking block 32 extends in the opposite direction to the first locking block 31. The fourth locking block 42 and the second locking block 41 form a sealing groove 43. The first locking block 31 extends into the sealing groove 43 and engages with the second locking block 41. The third locking block 32 extends into the sealing groove 43 and engages with the fourth locking block 42.

[0066] This arrangement ensures a tight connection between the baffle 3 and the sealing structure 4, further improving the sealing effect and effectively preventing the intrusion of condensate or moisture.

[0067] As a preferred example of this utility model, such as Figure 6 As shown, a reinforcing structure 216 is provided between the door body 21 and the first protruding edge 212.

[0068] This design improves the structural strength of the door body 21, making it more robust and durable, and able to adapt to the complex usage environment of cooking equipment.

[0074] This arrangement improves the heat dissipation uniformity and heat dissipation effect of the door assembly.

[0075] As a preferred example of the present utility model, as Figure 6 shown, a second heat dissipation structure 2141 is provided on a side of the welding groove 214 away from the cooking cavity.

[0076] This arrangement further enhances the heat dissipation capability of the door assembly, ensures that the door assembly can maintain a good working state during long-term use, and reduces various problems caused by overheating.

[0077] Specifically, the second heat dissipation structure 2141 is configured as heat dissipation holes, and there are a plurality of heat dissipation holes.

[0078] This arrangement improves the heat dissipation uniformity and heat dissipation effect of the door assembly.
