COOKING APPARATUS USING MICROWAVE

摘要

A cooking apparatus using a microwave is provided to maintain a leakage blocking performance of the microwave stably in response to a gap variation of a main body and a door by enhancing an attenuation property. In a cooking apparatus using a microwave, a main body(10) includes a cooking space(11) inside, wherein one side of the cooking space(11) is opened. A microwave source mounted on the main body(10) supplies the microwave to the cooking space(11). A door(20) is coupled with the main body(10) to open/close the cooking space(11) selectively. A multi-layer choke seal(30) is formed at the door(20) for preventing the microwave from leaking between the main body(10) and the door(20) and is formed to have different resonant frequency and consists of different LC resonant circuits.
