Abstract

본 발명에 따른 팬히터의 솔레노이드 밸브 제어장치는 교류전원을 정류하는 정류브리지(14)와; 사용자가 팬히터를 작동시키면 초기에는 제1제어신호(P1)를 "하이"로, 제2제어신호(P2)를 "로우"로 출력한 후, 약 2초정도 시간이 경과되면 제1신호(P1)를 "로우"로 하고, 제2제어신호를(P2)를 소정의 듀티비를 제어하는 마이콤(11); 상기 마이콤(11)의 제1제어신호(P1)에 따라 온,오프되어 정류브리지(14)의 출력을 솔레노이드 벨브에 연결 혹은 차단시키는 릴레이(RL1); 상기 제2제어신호(P2)에 따라 온, 오프되는 스위칭부(18); 상기 스위칭부(18)를 통해 인가되는 정류된 전압을 소정 전압으로 안정화시키는 레귤레이터(16)로 구성되어 순간정전에 솔레노이드 밸브가 오프되지 않도록 한다.The solenoid valve control device of the fan heater according to the present invention includes a rectifying bridge 14 for rectifying an AC power source; When the user operates the fan heater, the first control signal P1 is initially output "high" and the second control signal P2 is output "low". After about 2 seconds, the first signal P1 is output. A microcomputer 11 for setting " low " and controlling the predetermined duty ratio with the second control signal P2; A relay RL1 that is turned on or off according to the first control signal P1 of the microcomputer 11 to connect or disconnect the output of the rectifying bridge 14 to a solenoid valve; A switching unit 18 that is turned on or off according to the second control signal P2; The regulator 16 is configured to stabilize the rectified voltage applied through the switching unit 18 to a predetermined voltage so that the solenoid valve is not turned off at the momentary power failure.
