Therefore, the opening / closing port (32) coupled to the shaft (31) of the solenoid valve (30) moves upward to close the oil pipeline in the fuel tank direction and open the oil pipeline in the direction of the vaporizer.

상기와 같이 기화기 방향의 송유관이 개방되면 전자펌프(60)에 의해 펌핑된 연료는 기화기를 통해 버너로 공급되어 점화트랜스970)에 의해 착화되고, 또한 송풍모터(80)가 제어부(40) 제어신호에 따라 구동되어 연료의 연소에 필요한 공기를 버너로 공급하게 된다(109 내지 110).The fuel pumped by the electromagnetic pump 60 is supplied to the burner through the vaporizer and is ignited by the ignition transformer 970. When the blower motor 80 is controlled by the control unit 40, To supply the air required for combustion of the fuel to the burner (109 to 110).

상기와 같이 본 발명은, 로터리히터의 초기점화시 전자펌프를 통해 버너로 공급되는 연료를 기설정된 시간동안 연료탱크로 귀환시킴에 따라 전자펌프내에 잔류하고 있는 공기를 연료와 함께 연료탱크로 드레인시킬 수 있어 오일연소기의 초기점화시 전자펌프내에 남아있는 공기가 연료와 함께 분사됨으로 인해 발생되는 도중실화를 방지할 수 있다.As described above, in the initial ignition of the rotary heater, the fuel supplied to the burner through the electromagnetic pump is returned to the fuel tank for a predetermined time, and the air remaining in the electromagnetic pump is drained to the fuel tank together with the fuel It is possible to prevent the misfire occurring during the initial ignition of the oil burner caused by the air remaining in the electromagnetic pump being injected together with the fuel.
