Abstract

본원 발명은 물의 부력을 이용하여 커패시턴스의 변화를 측정하여 수위를 판단하는 세탁기용 수위감지장치에 관한 것으로서, 세탁조의 하부와 튜브를 통해 연결되도록 하면에 돌출관이 형성된 용기와, 상기 용기의 상면에 장착되어 상기 용기의 내부와 외부를 차단하는 실링체와, 상기 실링체의 하면에 부착되고 전극을 띠는 고정체와, 상기 고정체와 대향되도록 상기 용기의 내부에 위치하고 전극을 띠는 부표와, 상기 고정체 및 부표 사이에 위치하는 유전체와, 상기 고정체 및 부표에 연결되어 커패시턴스를 체크하는 마이컴으로 구성되어 고정체와 부표의 간극 변화에 따라 변화되는 커패시턴스를 이용하여 수위를 감지하는 것을 특징으로 한다.The present invention relates to a water level sensor for a washing machine for measuring a change in capacitance by using a buoyancy force of water to determine a water level, the container having a protruding tube formed on a lower surface of the washing tank so as to be connected through a tube, and an upper surface of the container. A sealing body mounted to block the inside and the outside of the container, a fixing body attached to the bottom surface of the sealing body and having an electrode, a buoy placed inside the container so as to face the fixing body, and having an electrode buried therein; It is composed of a dielectric placed between the fixture and the buoy, and a microcomputer connected to the fixture and the buoy to check the capacitance to detect the water level by using the capacitance changed according to the gap change between the fixture and the buoy. do.
