Claims (4)
- (정정) 입력되는 전원전압을 강압한 다음 그 강압된 AC전압을 전파정류하도록 된 전원부(1)와, 이 전원부(1)의 정류전압을 전압분배작용에 따라 분압하도록 된 입력전압 검출부(2)와, 그리고 이 입력전압 검출부(2)의 분압된 전압값을 판단한 다음 그 판단결과에 따라 소정시간 지연된 동작제어신호를 출력하도록 된 마이컴(3)과, 이 마이컴(3)의 동작제어신호에 의해 상기 전원부(1)의 릴레이스위치(4)의 접점을 절환하도록 된 릴레이 절환부(5)와, 상기 마이컴(3)의 소정시간 지연된 동작제어신호에 의해 브러쉬모터(6)에 위상제어된 동작전압을 공급하도록 된 모터구동부(7)와, 상기 전원부(1)의 정류전압을 공급받아 그 위상이 제로인점에서만 출력한 다음 그 출력된 위상전압을 상기 마이컴(3)으로 입력시키도록 된 전원위상 검출부(8)를 포함하여 구성된 진공청소용 회전브러쉬의 전압자동 절환회로에 있어서, 상기 입력전압 검출부(2)는 전압분배 작용을 할 수 있도록 된 저항(Ra,Rb)과 입력전압의 위상이 제로가 되는 점만을 선택하도록 된 다이오드(D1)로 구성되고 상기 릴레이 절환부(5)는 마이컴(3)의 동작제어신호에 의해 릴레이스위치(4)의 접점을 절환토록 하는 트랜지스터(TR2)와 릴레이스위치(4)의 코일(L1)로 구성된 것을 특징으로하는 진공청소기용 회전브러쉬의 전압자동 절환회로.
