TECHNICAL FIELD
[0001] The present application relates to the technical field of cooking devices, in particular to a cooking device with a sealing structure. BACKGROUND
[0002] At present, in the household cooking device, microwave heating is a common cooking method, and the microwave generated by the microwave assembly of the cooking device is used to heat and cook food. In order to effectively use the microwave and avoid leakage, the microwave assembly and the cooking chamber where the food is placed are separately arranged, and the microwave generated by the microwave assembly is injected into the cooking chamber through the microwave port on the cooking chamber.
[0003] The microwave port is generally provided with a microwave transmission plate made of mica material. The mica material does not shield microwaves, which can ensure that the microwaves penetrate the microwave transmission plate and enter the cooking chamber. At the same time, the microwave transmission plate can also block the smoke in the cooking chamber from flowing to the microwave assembly through the microwave duct, thereby preventing the microwave assembly from being polluted and damaged. Therefore, the microwave port must be provided with a corresponding sealing structure to ensure the sealing of the smoke. Generally, the heat of a microwave oven is generated inside the food and radiated outward, so during use, the cooking chamber rarely appears long-term high temperature. The sealing structure of the existing microwave port can achieve good sealing. However, in a cooking device with multiple cooking methods such as microwave baking and steaming, when baking and steaming, the heat generated by the external heat source heats the food from the outside to the inside, so during use, the cooking chamber often appears long-term high temperature, which causes the sealing structure of the microwave port to be in a high-temperature environment for a long time. The sealing elements such as the elastic sealing ring in the sealing structure are aged at high temperature, resulting in loss of elasticity and even damage, greatly reducing the sealing performance of the sealing structure, and the sealing effect of the sealing structure is lost.

[0037] The utility model discloses a cooking device with sealing structure provides a kind of, as shown in the drawing, Figures 1-4 It is set between microwave port 11 and microwave transmission plate 12 in microwave port 11, including: cooking cavity 1, microwave port 11 is set on its inner wall, and the microwave generated by cooking device is shot into cooking cavity 1 by microwave port 11 by microwave guide pipe 13;Sealing element 2 is set in microwave port 11;Cooling assembly 3 is located at the side of sealing element 2 towards cooking cavity 1, and cooling assembly 3 is attached to sealing element 2 to cool sealing element 2.
[0038] Compared with the prior art, the application has the following beneficial effects: the cooling assembly 3 is attached to the sealing element 2 of the sealing structure of the microwave opening 11, and when high temperature occurs in the cooking cavity 1, the cooling assembly 3 cools and reduces the surface temperature of the sealing element 2, avoids high-temperature aging of the sealing element 2, maintains the proper elasticity, and ensures that the sealing effect of the sealing structure is long-term effective.
[0039] In the technical solution of the embodiment, as shown in FIG. 1, the cooling assembly 3 includes a heat absorption part 31 and a conduction part 32. Figures 5-6 The heat absorption part 31 is attached to the sealing element 2, and at the same time, the heat absorption part 31 and the conduction part 32 are surrounded to form a refrigerant cavity 33, which is connected to the cooling pipeline of the cooking device. Under the action of the cooling pipeline of the cooking device, the cooling liquid circulating in the refrigerant cavity 33 continuously carries away the heat absorbed by the heat absorption part 31 attached to the sealing element 2, thereby reducing the surface temperature of the sealing element 2. In addition, the cooling assembly 3 not only reduces the surface temperature of the sealing element 2, but also improves the uniformity of the surface temperature of the sealing element 2, avoiding deformation and warping of the sealing element 2 caused by uneven heating.
[0040] Specifically, as shown in FIG. 2, a through groove 321 is provided on the conduction part 32, and the through groove 321 has a folded edge at the groove opening. Figures 7-8 The folded edge is sealed and connected to the heat absorption part 31 by welding, so that the through groove 321 is closed by the heat absorption part 31 to form the refrigerant cavity 33. The folded edge is sealed and connected to the heat absorption part 31 by welding, which can realize stable sealing of the heat absorption part 31 to the through groove 321 and ensure that the cooling liquid flowing in the refrigerant cavity 33 will not leak. At the same time, the welding method also has good long-term temperature resistance and is suitable for the long-term high-temperature environment of the cooking cavity 1.
[0041] In other preferred embodiments, the folded edge includes a first folded edge 322 and a second folded edge 323, and the first folded edge 322 and the second folded edge 323 are respectively located on both sides of the groove opening of the through groove 321. The first folded edge 322 and the second folded edge 323 increase the welding area with the heat absorption part 31, improve the welding strength and sealing performance, and at the same time, the first folded edge 322 and the second folded edge 323 are respectively located on both sides of the groove opening of the through groove 321, which is convenient for welding operation in the processing process and improves the production efficiency.

In order to realize that the heat absorbing part 31 fully absorbs the heat of the surface of the sealing element 2, the heat absorbing part 31 needs to be fully attached to the sealing element 2, and the heat absorbing part 31 can be accurately and stably installed and fixed at the microwave port 11 through the positioning hole 313. The fixed mode can be screws, rivets, etc. In addition, since the heat absorbing part 31 is installed and fixed first, the inlet port 311 and the outlet port 312 are arranged on the heat absorbing part 31, so that the connection with the cooling pipeline of the cooking device can be completed when the heat absorbing part 31 is installed and fixed, ensuring the stability and reliability of the connection. According to the actual situation of the cooking device, in order to meet the attachment of the heat absorbing part 31 and the sealing element, a through hole corresponding to the inlet port 311, the outlet port 312 and the positioning hole 313 can be formed on the sealing element 2 to facilitate the connection of the cooling pipeline and the installation and fixation.

The first sealing part 211, the second sealing part 212 and the attachment part 22 form a C-shaped groove 213, and the C-shaped groove 213 has an opening 214 facing the center of the microwave port 11. The sealing element 2 is placed in the microwave port 11, and then the edge of the microwave transmission plate 12 is clamped into the opening 214 to realize the sealing connection of the microwave transmission plate 12 on the sealing element 2. In this way, by clamping the edge of the microwave transmission plate 12 into the C-shaped groove 213, the sealing element 2 is attached to the edge of the microwave transmission plate 12, realizing the sealing connection of the microwave transmission plate 12 and the sealing element 2; after the sealing element 2 is installed in the microwave port 11, the sealing element 2 is also attached to the edge of the microwave port 11, realizing the sealing connection of the sealing element 2 and the microwave port 11, thereby realizing the sealing connection of the microwave port 11 and the microwave transmission plate 12.
[0045] In the technical scheme applied to the embodiment, the heat absorbing part 31 of the cooling assembly 3 not only attaches to the sealing element 2, but also plays a role in supporting and fixing the sealing element 2, because the microwave transmission plate 12 is also installed in the sealing element 2. Therefore, the size and shape of the heat absorbing part 31 and the attachment part 22 are matched, so that the heat absorbing part 31 can provide sufficient supporting force to the attachment part 22 to maintain the support and fixation of the sealing element 2 to the microwave transmission plate 12.
