Abstract

본 발명은 세탁기의 용수를 배수하기 위하여 설치된 배수용 드레인 펌프를 제어하는 것에 관한 것이다.The present invention relates to controlling a drain pump for drainage installed to drain water from a washing machine.

더욱 구체적으로는 배수 행정시 드레인 펌프와 세탁조 사이에 잔류하는 공기에 의하여 펌프 임펠러 부근에 형성된 공동(cavity)을 제거하기 위한 드레인 펌프 제어회로에 관한 것이다.More specifically, the present invention relates to a drain pump control circuit for removing a cavity formed near the pump impeller by air remaining between the drain pump and the washing tank during the drain stroke.

본 발명의 배수펌프 제어회로는, 배수 행정에 맞추어 행정을 제어하는 마이크로프로세서, 상기 마이크로프로세서에 연결되어 있으며 제어 신호에 의하여 작동하는 트라이악으로 구성되며, 상기 트라이악의 타단부는 드레인 펌프의 모타에 연결되어 있으며 배수 행정중에 온/오프를 반복하는 것을 특징으로 한다.The drain pump control circuit of the present invention comprises a microprocessor for controlling the stroke according to the drain stroke, and a triac connected to the microprocessor and operating by a control signal, and the other end of the triac is connected to the motor of the drain pump. It is connected and characterized in that the on / off repeats during the drain stroke.
