Abstract

본 발명은 전자레인지에 관한 것으로, 종래의 장치는 소자의 불량이나 쇼트등 이상이 발생하면 전자레인지의 동작을 오프시켜도 마그네트론 구동릴레이가 온되어 마그네트론이 발진작용을 하는 수가 있는데, 이와같이 이상동작을 하여도 이를 방지할 수 없는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 사용자의 조작에 따라 마그네트론을 구동하기 위한 제어신호를 출력하는 마이크로 컴퓨터와, 상기 마이크로 컴퓨터의 제어신호에 따라 마그네트론구동릴레이를 온오프시키는 릴레이구동부와, 상기 마이크로 컴퓨터의 제어신호와 릴레이구동부의 출력신호를 앤드조합하여 그에 따라 시스템 각 부의 전원공급을 차단하는 전원차단부로 구성한 전자레인지의 마그네트론 제어장치를 창안한 것으로, 이의 작용을 통해 즉, 마이크로 컴퓨터의 제어신호와 마그네트론구동릴레이의 온/오프상태를 검출하여 마그네트론이 비정상적으로 동작시에는 전원공급을 차단함으로써 제품을 보호할 수 있는 효과가 있다.The present invention relates to a microwave oven. In the conventional apparatus, when an element defect or short circuit occurs, the magnetron drive relay can be turned on to operate the magnetron even when the microwave oven is turned off. There was also a problem that can not be prevented. The present invention provides a microcomputer for outputting a control signal for driving the magnetron according to a user's operation, and a relay driver for turning on and off the magnetron driving relay according to the control signal of the microcomputer. Invented a magnetron control device for a microwave oven composed of a power cut-off unit which cuts the power supply of each part of the system according to the AND combination of the control signal of the microcomputer and the output signal of the relay driver. By detecting the on / off state of signal and magnetron driving relay, it can protect the product by shutting off the power supply when the magnetron is abnormally operated.
