제3도는 압력감지장치의 개략도,3 is a schematic diagram of a pressure sensing device,

제4도는 세탁기의 개략도,4 is a schematic view of a washing machine,

제6도는(가) 내지(마)는 일반적인 세탁기의 수위표시도,6 is a water level display of a general washing machine,

제7도는 본 발명에 적용되는 세탁기의 마이콤 주변회로도.7 is a microcomputer peripheral circuit diagram of a washing machine applied to the present invention.

Claims (1)

세탁조(22)의 수위 변화에 의한 에어챔버(25)의 공기압변화에 의해 콜피츠발진회로의 발진주파수(fosc) 변화되는 것을 마이콤(2)이 인지하여 입력값을 몇단계로 나누어 각 단계에 따른 표시소자를 구동하여 현재수위를 세분화 표시하되, 급수모드일때는 검출되는 수위에 대응하여 수위표시판(33)의 표시소자(LED1-LED10)를 순차적으로 점등시키고, 배수모드일때는 순차적으로 소등시키는 것을 특징으로 하는 세탁기의 수위세분화 표시방법.The microcomputer 2 recognizes that the oscillation frequency f osc of the Colpitts oscillation circuit is changed by the change in the air pressure of the air chamber 25 due to the change in the water level of the washing tank 22, and the input value is divided into several steps in each step. The display device is driven to display the present water level in subdivided mode. In the water supply mode, the display elements LED 1 to LED 10 of the water level display panel 33 are sequentially turned on in response to the detected water level. The water level subdivision display method of the washing machine characterized by turning off. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
