Abstract

본 발명은 연소기에 입력되는 전압의 변동에 따른 연소불안 현상을 방지하기 위해 송풍모터의 회전수 변화에 대해 펌프의 연료공급 주파수를 조절하는 팬히터용 연소기의 연소조절방법에 관한 것이다.The present invention relates to a combustion control method of a combustor for a fan heater which adjusts a fuel supply frequency of a pump with respect to a change in rotational speed of a blower motor in order to prevent combustion instability caused by a change in voltage input to the combustor.

본 발명은 송풍모터와, 상기 송풍모터의 회전수를 감지하는 회전수감지센서와, 액체연료를 공급하는 전자펌프와, 시스템을 제어하는 마이컴으로 구성된 팬히터용 연소기의 연소조절 방법에 있어서, 상기 회전수감지센서의 감지결과에 따라 전자펌프의 연료공급 주파수를 조절하여 상기 송풍모터의 회전수에 대응되도록 하는 것을 특징으로 한다. 따라서 본 발병은 항상 정상적인 연소상태를 유지할 수 있게 되는 잇점이 있다.The present invention relates to a combustion control method of a combustor for a fan heater comprising a blower motor, a rotation speed sensor for sensing the rotational speed of the blower motor, an electronic pump for supplying liquid fuel, and a microcomputer to control the system. The fuel supply frequency of the electronic pump is adjusted according to the detection result of the water sensor so as to correspond to the rotational speed of the blower motor. Therefore, this attack has the advantage that it can always maintain a normal combustion state.
