Abstract

본 발명은 가스보일러의 착화시 가스압력제어방법에 관한 것으로서, 특히 착화시 역풍 또는 배기연도의 장애물등에 의한 배기팬의 회전수변동에 따라 버너에 공급하는 가스의 압력을 제어하고 배기팬의 회전수가 적정회전수에서 크게 벗어날 때에는 가스공급을 중지시킴으로써 안전하고 신속한 착화가 이루어지도록 하고 폭음발생등의 위험을 줄이는 가스보일러의 착화시 가스압력제어방법에 관한 것이다.The present invention relates to a gas pressure control method for ignition of a gas boiler, and more particularly, to control the pressure of the gas supplied to the burner according to the rotational speed of the exhaust fan caused by a back wind or an obstruction of the exhaust flue during ignition. The present invention relates to a method of controlling gas pressure when the gas boiler is ignited by stopping the gas supply when the engine is far out of the proper rotational speed, thereby enabling safe and rapid ignition and reducing the risk of explosion.

본 발명의 착화시 가스압력제어방법은 착화시 팬구동 및 회전수감지부(7)로부터의 신호에 의해서 배기팬(6)의 실제적인 현재회전수를 감지하여, 배기팬(6)의 현재회전수에 대응하는 최적의 가스압력이 되도록 가스밸브(2)를 제어하는 데이타를 설정하고, 배기팬(6)의 현재 회전수와 미리 설정된 착화시 적정회전수를 비교하여 현재회전수가 적정회전수에 대해서 일정허용오차범위내에 있는지를 판단하여, 배기팬(6)의 현재회전수가 적정회전수에 대해서 일정허용오차범위내에 있지 않을 경우에 가스공급을 하지 않도록 가스밸브(2)를 제어하고, 배기팬(6)의 현재회전수가 적정회전수에 대하여 일정허용오차범위내에 있을 경우에 상기 단계에서 설정된 데이타에 따라 현재회전수에 대응하는 최적의 가스압력이 되도록 가스밸브(2)를 제어하는 것을 특징으로 한다.The ignition gas pressure control method of the present invention detects the actual present rotational speed of the exhaust fan 6 by the signal from the fan driving and rotational speed sensing unit 7 at the ignition, and thus the present rotational speed of the exhaust fan 6. The data for controlling the gas valve 2 is set so that the optimum gas pressure corresponding to, and the present rotational speed of the exhaust fan 6 is compared with the preset rotational speed at the time of ignition, and the current rotational speed is It is judged whether or not it is within a certain allowable error range, and the gas valve 2 is controlled so as not to supply gas when the current rotational speed of the exhaust fan 6 is not within a certain allowable error range with respect to the proper rotational speed, and the exhaust fan ( When the current rotation speed of 6) is within a certain allowable error range with respect to the proper rotation speed, the gas valve 2 is controlled to be the optimum gas pressure corresponding to the current rotation speed according to the data set in the above step. The.
