Abstract

본 발명은 전자레인지 리셋제어장치 및 그 제어방법에 관한 것으로, 종래의 전자레인지 리셋제어장차는 제어부에 대하 별도의 보호장치가 없기 때문에 외부에서 노이즈가 발생하면 이에 영향을 받아 오동작하기 쉬우므로 이를 해결하기 위해 데이타를 교환하여 상호 감시하는 2개의 제어부를 사용하여 외부로부더 잡음이 인가되어 하나의 제어부가 오동작하여도 이 오동작하는 제어부를 리셋시키고, 나머지 다른 정상적인 제어부로 리셋제어를 수행함으로써 제품의 질을 개선하고 제품에 대한 소비자의 신뢰도를 향상시킬 수 있는 효과가 있다.The present invention relates to a microwave reset control apparatus and a control method thereof. In the conventional microwave reset control apparatus, since there is no separate protection device for the control unit, when noise occurs from the outside, it is easy to be affected by the malfunction and thus solves this problem. In order to exchange data, two noise controllers are used to monitor each other to reset the malfunctioning controller even if one controller malfunctions, and then performs reset control with the other normal controllers. It has the effect of improving the quality of the product and improving the consumer's confidence in the product.
