Double-frequency microwave oven door and double-frequency microwave oven

Abstract

The invention provides a double-frequency microwave oven door and a double-frequency microwave oven. The double-frequency microwave oven comprises a panel, a door body and a cover board, wherein the door body comprises a door frame and a choke structure which is arranged at the periphery of the door frame and is used for shielding micro-wave leakage, wherein the choke structure comprises a choke groove, a first choke tooth and a second choke tooth. By adopting the double-frequency microwave oven door provided by the invention, a microwave with one wavelength is shielded by matching of the first choke tooth and the choke groove under the condition that an attenuating material is not additionally arranged, and the microwave with another wavelength is shielded by matching of the second choke tooth and the choke groove. Thus, the microwaves with the two different wavelengths can be shielded by the choke structure, and the leakage of the microwaves is avoided, so that the damage of the microwaves to a human body is effectively prevented, the double-frequency microwave oven door is simple in structure, and easy to process and manufacture, and the manufacturing cost is not increased.

Description

technical field [0001] The invention relates to a household appliance, in particular to a dual-frequency microwave oven door and a dual-frequency microwave oven provided with a dual-frequency microwave oven door. Background technique [0002] Domestic microwave ovens or industrial microwave heating equipment are devices that use magnetrons to convert external electrical energy into microwaves and heat them through the interaction of substances and microwave fields, which can simultaneously heat the surface and interior of food, thereby achieving rapid cooking of food . It generally includes a magnetron for generating microwaves, a furnace body, a power supply, a control circuit, and an outer cover. Wherein the part of the furnace body mainly includes a furnace chamber for storing food, and a furnace door is installed on the front of the furnace chamber. The function of the oven door is to facilitate taking and placing food and observing the cooking situation. The oven door...

AI Technical Summary

Problems solved by technology

[0003] Household microwave ovens or industrial microwave oven heating equipment generally use microwaves with a frequency of 2.45GHz to heat food, that is, microwaves with a single frequency are used to heat food. This heating method is prone to uneven heating; therefore, sometimes 2.45GHz is used It works at the same time as the two frequencies of 5.8GHz to make the food heated evenly. However, the oven door of this kind of microwave oven can only be used to shield the microwave of the 2.45GHz frequency, and has no inhibitory effect on the microwave of the 5.8GHz frequency. Therefore, when used as an effective When the microwave oven or microwave heating equipment with two frequencies working at the same time, there will be a safety problem of large microwave leakage
