Abstract

본 발명은 전자레인지의 마그네트론 구동 제어장치 및 방법에 관한 것으로, 종래의 전자레인지의 마그네트로구동 제어장치는 마그네트론 구동부가 오직 마이크로 컴퓨터의 릴레이구동신호에 의해서 구동 되기 때문에 마이크로 컴퓨터의 폭주나 오동작이 발생한 경우에도 즉시, 마그네트론구동부는 마그네트론을 구동하는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 마이크로 컴퓨터의 릴레이구동신호만을 가지고 구동하는 것이 아니라 외부로부터 마그네트론 구동을 필요로 하는 기능이 선택되었는지를 판단하여 마그네트론을 구동 시킨다. 다시말해, 외부에서 마그네트론 구동이 필요한 기능의 키를 입력받아야만 마그네트론이 발진할 수 있기 때문에 마이크로 컴퓨터의 폭주나 오동작으로 인해 마그네트론이 자동발진하는 것을 방지할 수 있는 효과가 있는 전자레인지의 마그네트론 구동 제어장치 및 방법을 창안한 것이다.The present invention relates to a magnetron driving control apparatus and method of a microwave oven, and the magnetron driving control apparatus of a conventional microwave oven because the magnetron driving unit is driven only by the relay drive signal of the microcomputer, congestion or malfunction of the microcomputer has occurred. Even if immediately, the magnetron drive unit had a problem driving the magnetron. The present invention drives the magnetron by determining whether a function requiring the magnetron drive is selected from the outside, instead of driving with only the relay drive signal of the microcomputer to solve such a conventional problem. In other words, since the magnetron can be oscillated only when a key of a function that requires magnetron operation is input from the outside, the magnetron drive control device of the microwave oven, which is effective to prevent the magnetron from automatically oscillating due to the runaway or malfunction of the microcomputer. And the invention.
