Abstract

본 발명은 팬히터의 연소기 안전운전 제어 방법에 관한 것으로, 일반적인 팬히터 예열완료후 점화플럭의 구동에 의해 기화된 가스를 기화기에서 연소시키고 염검지기로 부터 검지된 전압에 따라 연소기를 제어하게 되는 바 이는 연소용 흡입공기의 습도량에 따라 산소농도 변화에 대한 염전압의 변화를 고려치 않기 때문에 이로 인해 측정 산소농도 염전압을 잘못 판정하여 계속 정상소화 시킴으로써 인면에 치명적인 악영향을 끼치게되는 문제점이 있었다.The present invention relates to a method for controlling the safe operation of the combustor of a fan heater, and after the general fan heater preheating is completed, the gas vaporized by driving the ignition flash is combusted in the vaporizer and the combustor is controlled according to the voltage detected by the salt detector Since the change in the salt voltage with respect to the oxygen concentration change is not taken into account according to the humidity of the inhalation air, this causes a fatal adverse effect on the human face by erroneously determining the measured oxygen concentration salt voltage and continuing to normalize it.

이를 보완하기 위한 본 발명은 연소용 송풍기의 흡기 3측의 습도센서를 검지한 연소용 흡입공기의 습도량에 따라 마이콤은 모드별로 설정된 습도량을 결정하고 그 습도량에 따른 산소농도 염전압 기준치를 염검지기로부터 검지된 산소농도 불꽃 전류치와 비교하여 산소농도 불꽃 전류치가 작으면 자동소화하고 크면 정상연소 동작을 수행하게 되는 효과가 있는 것이다.According to the present invention to compensate for this, according to the humidity amount of the combustion intake air detecting the humidity sensor of the intake three sides of the combustion blower, the microcomputer determines the humidity level set for each mode and the oxygen concentration salt voltage reference value according to the humidity amount. Compared with the oxygen concentration flame current value detected from the salt detector, if the oxygen concentration flame current value is small, the automatic extinguishing and the normal combustion operation is performed.
