Abstract

본 발명은 세탁수의 공급수압을 감지하여 세탁수의 급수시간을 산정하고, 이에 의거하여 정확한 세탁 소요시간을 산출, 표시할 수 있도록 한 세탁소요시간 산출회로 및 방법에 관한 것이다.The present invention relates to a washing time calculation circuit and method for detecting the water supply pressure of the washing water to calculate the water supply time of the washing water, and to calculate and display the required washing time based thereon.

본 발명에 따른 급수압감지부는 급수관의 내부의 적수에 축에 의하여 회동 및 복귀가능하도록 설치되고, 급수되는 세탁수의 수압에 비례하여 회동하는 칸막이부재와, 상기 급수관의 내부에 상기 칸막이 부재와 인접하여 일정간격으로 설치된 복수개의 발광다이오드 및 상기 급수관의 내부에 칸막이부재를 중심으로 상기 발광다이오드와 대향되는 위치에 설치된 복수개의 수광트랜지스터를 구비한다.The water supply pressure detecting unit according to the present invention is installed to be rotatable and returnable by the shaft to the water in the water supply pipe, the partition member rotating in proportion to the water pressure of the wash water being supplied, and adjacent to the partition member inside the water supply pipe. A plurality of light emitting diodes provided at regular intervals and a plurality of light receiving transistors installed in a position facing the light emitting diode centered on the partition member in the interior of the water supply pipe.
