Abstract

본 발명은 세탁기의 급수중 단수시나 수도사정이 원활치 못함을 검출하여 세탁기에 적절하지 않다고 판단되면 급수를 중단하고, 경보를 울려주며, 급수이상 신호를 외부로 표시해 알려주되, 급수이상을 조기에 검출할 수 있도록 한 세탁기의 급수 이상 경보회로에 관한 것으로, 수위감지 센서를 채용하고 마이크로 컴퓨터의 제어로 구동되는 세탁기에 있어서, 급수개시시 수위감지수단(2)으로부터 입력되는 초기 주파수를 기억하고, 일정시간 경과후 수위감지수단(2)으로부터 입력되는 주파수를 상기 초기 주파수와 비교하여 급수의 이상 유무를 판단함을 특징으로 한다.The present invention detects the water shortage during the water supply of the washing machine or when the water is not smoothly determined to be unsuitable for the washing machine, stops the water supply, sounds an alarm, and displays the water supply abnormality signal to the outside to detect the water supply abnormality early. A water supply abnormality alarm circuit of a washing machine which enables the washing machine to be used, wherein the washing machine adopts a water level sensor and is driven by the control of a microcomputer. After the passage of time, the frequency input from the water level detecting means 2 is compared with the initial frequency to determine whether there is an abnormality of water supply.
