[0034] like Figure 1 to Figure 2 As shown, this embodiment provides a door structure, which includes a door frame structure 1, a door seal 2 and a metal interception layer 3. The door frame structure 1 is sleeved at the front end of the liner structure 4, and a door seal groove is provided between the door frame structure 1 and the liner structure 4. The door seal 2 is provided in the door seal groove, and the metal interception layer 3 is provided at the end of the door seal 2 inserted into the door seal groove. The metal interception layer 3 is used to intercept microwaves leaked between the door frame structure 1 and the liner structure 4.
[0035] By sealing the door frame structure 1 and the inner pot structure 4 with the door seal 2 set in the door sealing groove, leakage of steam from the inner pot can be avoided, thereby ensuring the heating efficiency of the inner pot. A metal interception layer 3 is set at the end of the door seal 2 inserted into the door sealing groove. The microwaves in the inner pot leak out from the top of the door seal 2, enter the door sealing groove and reach the gap on the connecting surface of the door seal 2. They will be intercepted by the metal interception layer 3 and reflected back into the inner pot. The microwaves leaked between the door frame structure 1 and the inner pot structure 4 are intercepted by the metal interception layer 3, thereby effectively avoiding harm to the human body caused by microwave leakage during food heating, thereby improving the safety of product use, meeting the safety needs of users, enhancing the market competitiveness of the product, and improving the user experience.
[0036] Optionally, the metal interception layer 3 includes a first interception layer 31 and a second interception layer 32, wherein the first interception layer 31 is sandwiched between the door seal 2 and the door frame structure 1, and the second interception layer 32 is sandwiched between the door seal 2 and the liner structure 4. When the microwaves in the liner leak out from the top of the door seal 2 and enter between the door seal 2 and the door frame structure 1, they will be intercepted by the first interception layer 31 and reflected back to the liner. When the microwaves in the liner leak out from the top of the door seal 2 and enter between the door seal 2 and the liner structure 4, they will be intercepted by the second interception layer 32 and reflected back to the liner, which effectively avoids the harm of microwave leakage to the human body during food heating. Optionally, the metal interception layer 3 also includes a transition layer 33, and the first interception layer 31 is connected to the second interception layer 32 through the transition layer 33. The first interception layer 31 and the second interception layer 32 are connected through the transition layer 33, so that the metal interception layer 3, as a whole, intercepts the microwaves leaked between the door frame structure 1 and the liner structure 4.
[0037] In some embodiments, the metal interception layer 3 is a metal coating coated on the door seal 2. The metal coating is coated on the surface of the door seal 2 by spraying, electroplating, oxidation, bluing, phosphate treatment or other methods.
[0038] In some embodiments, the metal interception layer 3 is a metal material wrapped on the door seal 2. Metal material refers to a material with properties such as gloss, ductility, easy conductivity, and heat transfer. The ductility of the metal material is relatively good, and it is convenient to wrap it on the door seal 2. The metal material can reflect microwaves and intercept microwaves leaked between the door frame structure 1 and the liner structure 4. In order to facilitate material acquisition and reduce costs, the metal interception layer 3 is optionally a tin foil wrapped on the door seal 2.
[0039] In some embodiments, the metal interception layer 3 is a metal mesh wrapped on the door seal 2. The metal mesh is a mesh structure, which can effectively reduce the weight of the metal interception layer 3, making the product lighter. At the same time, the metal mesh also has a certain microwave interception capability.
[0040] To facilitate the installation of the door seal 2, optionally, the door frame structure 1 includes a door frame body 11 and a folding structure 12 disposed on the door frame body 11, the liner structure 4 includes an liner body 41 and a flange structure 42 disposed on the liner body 41, and a door seal groove is formed between the folding structure 12 and the flange structure 42. Optionally, the flange structure 42 includes a first flange 421 and a second flange 422 connected to each other, the first flange 421 is in contact with the outer side of the liner body 41, and the second flange 422 is perpendicular to the first flange 421, the folding structure 12 includes a first flange 121 and a second flange 122 connected to each other, the first flange 121 is parallel to the first flange 421 and is spaced apart, and the second flange 122 is disposed at the front side of the second flange 422. The first interception layer 31 is sandwiched between the first folded edge 121 and the door seal 2 , the second interception layer 32 is sandwiched between the first flange 421 and the door seal 2 , and the transition layer 33 is located between the second side and the door seal 2 and is attached to the door seal 2 .
[0041] The present embodiment also provides a cooking utensil, including an inner pot structure 4 and the above-mentioned door body structure. The door frame structure 1 and the inner pot structure 4 are sealed by a door seal 2 arranged in the door sealing groove, which can prevent the steam in the inner pot from leaking out and ensure the heating efficiency of the inner pot. A metal interception layer 3 is arranged at the end of the door seal 2 inserted into the door sealing groove. The microwaves in the inner pot leak out from the top of the door seal 2, enter the door sealing groove and reach the gap on the connecting surface of the door seal 2. They will be intercepted by the metal interception layer 3 and reflected back into the inner pot. The microwaves leaked between the door frame structure 1 and the inner pot structure 4 are intercepted by the metal interception layer 3, which effectively prevents the leakage of microwaves from harming the human body during the heating of food, improves the safety of product use, meets the safety needs of users, enhances the market competitiveness of the product, and improves the user experience.
