Abstract

The present invention discloses a microwave oven screen door structure which includes a microwave oven cavity, a microwave oven door body is disposed on a front surface of the microwave oven cavity, aperiphery of the microwave oven door body and an opening flange of the microwave oven cavity body are provided with shielding layers, the shielding layers are disposed on the microwave oven door body, and a condition that microwave energy is sealed in the microwave oven cavity body is ensured. By setting multiple shielding structures, the microwave efficiency and shielding performance are ensuredin low frequency operation, and the size of the cavity body and the cost can be reduced by eliminating chute design.

Description

technical field [0001] The invention relates to the field of microwave ovens, in particular to a microwave shield door structure. Background technique [0002] Traditional microwave ovens use 2.45GHz magnetron as the microwave source, and the microwave oven door is generally designed with a 1 / 4 wavelength choke slot for 2.45GHz high frequency to guide the microwave to reverse the phase so that the microwave and the reflected wave at the oven door can be offset to prevent microwave leakage . However, if a low-frequency 900MHz microwave source is used, the choke groove needs to be designed with a wavelength of 1 / 4 of 82.5 mm, which is not practical in a miniaturized cavity. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies of the prior art above, the object of the present invention is to provide a microwave oven screen door structure, aiming at solving the problems of ensuring microwav...
