Abstract

본 발명은 세탁기 및 식기세척기의 인터럽트신호 발생장치에 관한 것으로, 종래에는 트랜스의 2차단교류전압을 이용하여 인터럽트신호를 발생시키므로 트랜스에 의한 위상지연으로 부하제어시 정확한 제로크로싱을 실현하기 어려운 문제점이 있었다. 따라서 본 발명은 인터럽트부에 전원전압을 신호원으로 인가시 여러부하를 구동하기 위한 트라이악의 출력단자에서 교류신호를 인가할 수 있도록 하므로서 외부에서 별도의 리드와이어를 사용하지 않고 기판상에서 간단하게 교류신호를 인가할 수 있도록 함으로써 정확한 제로크로싱을 실현할 수 있도록 하였다.The present invention relates to an interrupt signal generating device of a washing machine and a dishwasher. In the related art, an interrupt signal is generated by using a second-stage alternating voltage of a transformer. there was. Therefore, the present invention allows the AC signal to be applied from the output terminal of the triac for driving various loads when the power supply voltage is applied to the interrupt unit as a signal source, so that the AC signal is simply formed on the substrate without using a separate lead wire from the outside. It is possible to realize accurate zero crossing by applying.
