Abstract

본 발명은 세탁기나 또는 식기 세척기 등과 같이 물을 사용하는 가전 제품에 있어서, 물을 공급하는 급수 행정이 있으며 물을 순환시키는 드레인 펌프(drain pump)등과 같은 배수 펌프 사용시 소자의 고장에 의하여 발생되는 오버폴로우(overflow)를 방지하기 위한 안전회로에 관한 것이다.The present invention is a home appliance that uses water, such as a washing machine or a dishwasher, there is a water supply stroke for supplying water and the over-generation caused by the failure of the device when using a drain pump such as a drain pump (circulating water) The present invention relates to a safety circuit for preventing overflow.

더욱 구체적으로는 드레인 펌프, 급수 밸브, 수위 감지 센서, 트라이악등과 같은 제어 소자의 파손으로 인하여 발생되는 과다 급수를 방지하기 위한 오버플로우 방지용의 안전회로에 관한 것이다.More specifically, the present invention relates to a safety circuit for preventing overflow to prevent excessive water supply caused by damage to control elements such as a drain pump, a water supply valve, a water level sensor, and a triac.

본 발명의 오버플로우방지용 안전회로는, 물의 압력을 측정하는 압력 스위치, 상기 압력 스위치에서 전달되는 신호를 수신하여 행정을 제어하는 마이크로프러세서, 상기 마이크로프로세서의 제어 신호에 의하여 각각 급수 밸브와 배수 펌프를 작동시키는 제1 및 제2트라이악으로 구성되는 것을 특징으로 한다.An overflow prevention safety circuit of the present invention includes a pressure switch measuring water pressure, a microprocessor receiving a signal transmitted from the pressure switch to control the stroke, and a feed valve and a drain pump according to control signals of the microprocessor, respectively. It is characterized by consisting of the first and second triac to operate.
