Abstract

본 발명은 전기세탁기의 전압자동절환회로에 관한 것으로, 특히, 입력되는 전원전압의 범위에 따라 마이컴이 판단하여 릴레이스위치접점은 절환 혹은 유지되게 함으로써 변동될 전원전압이 인가되더라도 자동적으로 전압이 절환되게 됨으로 이에 따라 시스템이 파손되는 일이 방지되도록 한 전기세탁기의 전압자동전환회로에 관한 것으로서, 세탁조 구동용 회전모터(9)와 사용자의 동작지시을 키보드(12)를 통해 입력받도록 된 콘트롤 PCB부(10)등으로 구성된 전기세탁기의 시스템에 있어서, 인가되는 AC전압전원을 DC전압으로 변환시키는 전원공급부(1), 이 전원공급부(1)로 부터 공급되는 DC전압의 조건에 따라 하이신호 혹은 로우신호를 발생시키는 전압감지부(2), 그리고 이 전압감지부(2)로 부터 출력되는 하이 또는 로우신호를 판단하여 그 판단결과에 따라 시스템의 입력전압절환용 릴레이스위치(RY1,RY2)를 구동제어하는 제어부(3)로 이루어진 것을 특징으로 한 것이다.The present invention relates to a voltage automatic switching circuit of an electric washing machine. In particular, the microcomputer determines that the relay switch contact is switched or maintained according to the range of the input power supply voltage, so that the voltage is automatically switched even if the power supply voltage to be changed is applied. Accordingly, the present invention relates to a voltage automatic switching circuit of an electric washing machine, which prevents the system from being damaged. The control PCB unit 10 receives input of the washing motor driving rotary motor 9 and a user's operation instruction through the keyboard 12. In a system of an electric washing machine comprising a power supply, the power supply unit 1 converts an applied AC voltage power source into a DC voltage, and generates a high signal or a low signal depending on the condition of the DC voltage supplied from the power supply unit 1. The voltage sensing unit 2 and the high or low signal outputted from the voltage sensing unit 2 and Input voltage changeover relay switch of the LA system is characterized in that one made of a control unit 3 that controls the drive (RY 1, RY 2).
