Abstract

본 발명은 가스보일러의 역풍을 감지하고 제어하는 방법에 관한 것으로서, 더욱 구체적으로는 사용자가 시동 스위치를 눌러서 보일러를 작동시킬 때 가스보일러의 배기연도를 통하여 내부로 역풍이 유입되는 경우에 이것을 감지하고, 보일러의 동작을 정지시키는 제어방법에 관한 것이다.The present invention relates to a method of detecting and controlling a reverse wind of a gas boiler, and more particularly, to a method of detecting and controlling reverse wind when a user operates a boiler by pressing a start switch, , And a control method for stopping the operation of the boiler.

본 발명의 가스보일러의 역풍감지 제어방법은, 고속회전속으로 배기팬을 회전시켜 보일러 내부의 미배출된 연소가스를 제거하는 프리퍼지행정과, 상기 프리퍼지행정이 완료된 후에 저속으로 배기팬을 회전시키는 점화 행정을 포함하여 이루어지는 가스보일러의 연소제어방법에 있어서, 상기 점화행정에 사용되는 배기팬의 회전수를 측정하는 단계; 상기 측정된 배기팬의 회전수를 설정된 회전수와 비교하는 단계; 설정 회전수보다 측정 회전수가 적으면 점화행정을 수행하는 단계; 및 설정회전수보다 측정회전수가 크면 타이머를 작동시켜 시간의 경과를 측정하고, 소정시간이상 역풍이 감지되면 소화행정을 수행하는 단계로 구성되는 것을 특징으로 한다.The present invention provides a method for controlling the reverse flow of a gas boiler, comprising: a pre-purge stroke for rotating the exhaust fan to a high rotational speed to remove unburned combustion gas in the boiler; A method of controlling combustion of a gas boiler comprising an ignition step, comprising the steps of: measuring the number of revolutions of the exhaust fan used for the ignition stroke; Comparing the measured number of revolutions of the exhaust fan with the set number of revolutions; Performing an ignition stroke if the measured rotation speed is smaller than the set rotation speed; And if the measured rotation speed is greater than the set rotation speed, measuring the elapsed time of the timer by operating the timer, and performing a fire extinguishing process when a backward wind is detected for a predetermined time or more.
