Microwave shielding door body assembly and microwave cooking electric appliance

Abstract

The invention discloses a microwave shielding door body assembly and a microwave cooking electric appliance. The microwave shielding door body assembly comprises: a door body provided with a door plate; a door tooth structure arranged on the periphery of the door plate; and a door frame arranged on a cavity of the cooking electric appliance, wherein the door tooth structure comprises at least three layers of door teeth arranged in the thickness direction of the door plate, and the door frame is matched with the outer edge structure of the door teeth. The microwave cooking electric appliance is provided with the microwave shielding door body assembly. According to the microwave shielding door body assembly, two or more layers of door teeth are arranged on the periphery of the door plate, the microwave impedance effect can be improved, reflected waves and standing waves can be weakened, the power capacity of microwave transmission can be improved, the focusing phenomenon can be reduced, and the microwave shielding efficiency can be improved; and the door frame of the cavity is matched with the outer edge structure of the door tooth, and microwave leakage can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a microwave shielding door assembly with a microwave function cooking appliance and the microwave cooking appliance. Background technique [0002] With the improvement of people's living standards, the proportion of household cooking appliances is increasing year by year. The microwave function of microwave cooking appliances is to use the cooked food molecules to be subjected to the action of alternating electromagnetic fields in the cavity to generate high-frequency motion, and the molecules between molecules are high-speed and violent. The principle of frictional heat is used to heat food. When using the microwave function, if the microwave protection facilities are not in place, the generated microwave will leak radiation or the radiation exceeds the standard. The microwave shielding structure of the existing cooking appliance door body cannot completely and effect...

AI Technical Summary

Problems solved by technology

When using the microwave function, if the microwave protection facilities are not in place, the generated microwave will leak radiation or the radiation exceeds the standard. The microwave shielding structure of the existing cooking appliance door body cannot completely and effectively solve the situation of the microwave leakage radiation exceeding the standard. The incisor structure can only shield microwaves of a certain frequency, and cannot shield or reliably shield microwaves converted from frequency bands.
