Abstract

이 식기세정건조기는 대향하는 발광소자(20)와 수광소자(21)과를 갖는 광센서(18)에 의해 세정수의 광투과도를 검지하고, 검지된 세정수의 광투과도의 변화에 기초항 세정, 헹굼, 배수의 각 공정을 제어하는 세정기에 사용되는 것이며, 광센서(18)의 감도를 일정 감도가 되도록 보정해서 발광소자(20)에 흐르는 전류를 설정하고, 그후 세정동작을 개시하는 것으로서, 배수후 다음의 급수동작을 개시하고 나서, 일정시간 이내에 소정의 수위에 도달하면, 전회의 세정수가 남아있는 것으로 보고, 광센서(18)의 감도조정을 행하지 않고, 발광소자(20)에 표준 전류를 흘리도록 설정해서 세정동작을 개시하고 발광소자(20) 수광소자(20)의 특성의 불규일에 세정상태가 영향을 받지 않게 되어 있으며, 또 세정수의 남은 물이 있어도 세정효과는 영향을 받지 않는 세정기의 제어장치이다.
