[0034] like Figures 1 to 4 As shown, this embodiment provides a door structure, which includes a door frame structure 1 and a metal filling structure 3. The door frame structure 1 is sleeved on the front end of the liner structure 2. The door frame structure 1 includes a door frame body 11 and a folding structure 12 arranged on the door frame body 11. The liner structure 2 includes an liner body 21 and a flange structure 22 arranged on the liner body 21. The metal filling structure 3 is arranged between the folding structure 12 and the flange structure 22, and the metal filling structure 3 is used to intercept microwaves leaked between the door frame structure 1 and the liner structure 2.

[0035] A folding structure 12 is provided on the door frame body 11 of the door frame structure 1, and a flange structure 22 is provided on the inner tank body 21 of the inner tank structure 2, which is beneficial to the assembly and sealing of the door frame structure 1 and the inner tank structure 2. A metal filling structure 3 is provided between the folding structure 12 and the flange structure 22, and the microwaves leaked from the inner tank structure 2 will be intercepted by the metal filling structure 3 and reflected back into the inner tank. The microwaves leaked between the door frame structure 1 and the inner tank structure 2 are intercepted by the metal filling structure 3, which effectively avoids the harm of microwave leakage to the human body during food heating, improves the safety of product use, meets the user's safety needs, enhances the market competitiveness of the product, and improves the user's use experience.

[0036] To enhance the structural strength of the flange structure 22, optionally, the flange structure 22 includes a first flange 221 and a second flange 222 connected to each other, the first flange 221 is in contact with the outer side of the liner body 21, and the second flange 222 is perpendicular to the first flange 221. To enhance the structural strength of the folding structure 12, optionally, the folding structure 12 includes a first folding 121 and a second folding 122 connected to each other, the first folding 121 is parallel to the first flange 221 and is arranged at intervals, and the second folding 122 is arranged at the front side of the second flange 222. Microwaves in the liner are easily leaked from between the second folding 122 and the second flange 222, so it is necessary to fill the metal filling structure 3 between the second folding 122 and the second flange 222 to intercept the microwaves leaked between the door frame structure 1 and the liner structure 2, and effectively avoid the harm of microwave leakage to the human body during food heating.

[0037] In order to reduce the volume and weight of the metal filling structure 3, in some embodiments, the metal filling structure 3 is disposed between the end of the second flange 222 and the folding structure 12. In some embodiments, the metal filling structure 3 is disposed between the end of the second flange 122 and the folding structure 22. Of course, in some embodiments, a metal filling structure 3 is disposed between the end of the second flange 222 and the folding structure 12 and between the end of the second flange 122 and the folding structure 22 to improve the microwave interception capability and prevent microwave leakage from causing harm to the human body during food heating.

[0038] To ensure the interception capability of the metal filling structure 3 for leaked microwaves, the metal filling structure 3 is optionally arranged in a frame shape around the outer periphery of the inner liner structure 2. In other words, the metal filling structure 3 surrounds the outer periphery of the inner liner structure 2 in a circle to prevent microwave leakage from the inner liner.

[0039] To facilitate processing and manufacturing, in some embodiments, the metal filling structure 3 is a metal welding wire. The metal welding wire can be a solder wire, which is composed of a tin alloy and additives. Different types of welding wires will produce different fluxes. The welding wire part is to improve the auxiliary heat conduction of the welding wire during welding, remove oxidation, reduce the surface tension of the material to be welded, remove oil stains on the surface of the material to be welded, and increase the welding area. The solder wire can be soldered with an electric soldering iron or a laser. Under the welding action of the metal welding wire, the connection strength of the folding structure 12 and the flanging structure 22 is enhanced. The metal welding wire is a metal wire welding material used as a filler metal. The metal welding wire can be a carbon steel welding wire, a low alloy structural steel welding wire, an alloy structural steel welding wire, a stainless steel welding wire or a non-ferrous metal welding wire, etc.

[0040] There are two main welding methods for welding wire: fusion welding and pressure welding. Fusion welding is a method of heating the interface of the workpiece to a molten state during the welding process and completing the welding without applying pressure. During fusion welding, the heat source will quickly heat and melt the interface of the two parts to be welded to form a molten pool. The molten pool moves forward with the heat source and forms a continuous weld after cooling, connecting the two parts into one. Pressure welding is to achieve atomic bonding of two workpieces in a solid state under pressure, also known as solid-state welding.

[0041] In order to facilitate material acquisition and reduce costs, in some embodiments, the metal filling structure 3 is tin foil. The main components of tin foil are tin and aluminum, which is an alloy of tin and aluminum. Tin foil has good ductility and a certain microwave interception ability.

[0042] To ensure the sealing between the folded edge structure 12 and the flanged edge structure 22, the door structure may further include a door seal 4. A door seal groove is formed between the folded edge structure 12 and the flanged edge structure 22, and the door seal 4 is disposed in the door seal groove. The door frame structure 1 and the liner structure 2 are sealed by the door seal 4 disposed in the door seal groove, so that the steam in the liner can be prevented from leaking out, thereby ensuring the heating efficiency of the liner.

[0043] The present embodiment also provides a cooking utensil, comprising an inner pot structure 2 and the above-mentioned door body structure, a folding structure 12 is arranged on the door frame body 11 of the door frame structure 1, and a flange structure 22 is arranged on the inner pot body 21 of the inner pot structure 2, which is beneficial to the assembly and sealing of the door frame structure 1 and the inner pot structure 2, and a metal filling structure 3 is arranged between the folding structure 12 and the flange structure 22, and the microwaves leaked from the inner pot structure 2 will be intercepted by the metal filling structure 3 and reflected back into the inner pot, and the microwaves leaked between the door frame structure 1 and the inner pot structure 2 are intercepted by the metal filling structure 3, which effectively avoids the harm of microwave leakage to the human body during food heating, improves the safety of product use, meets the user's safety needs, enhances the market competitiveness of the product, and improves the user's use experience.
