이하 본 고안의 작용효과를 설명하면 다음과 같다.Hereinafter will be described the effect of the present invention.

상기한 바와 같은 본 고안은 연소에 필요한 공기를 버너모터(1)와 버너모터 블로우어(2)에 의해 오일버너(4) 안으로 빨아들이는 과정에서 폐가스토출구(9) 내의 일산화탄소의 량을 일산화탄소 감지센서(14)에 의해 감지하여 버너모터(1)의 알피엠(r.p.m)을 조절함으로써 오일버너(4) 내의 공기혼합비를 조절하고, 노즐(5)에서 분사되는 연로를 점화트랜스(6)에서 점화하며, 점화되어 연소된 연소가스는 챔버(7)와 방열기(8) 및 폐가스토출구(9)를 거쳐 실외로 토출된다. 그리고, 챔버(7)와 방열기(8)에 의해 데워진 공기는 팬모터(11)와 팬모터블로우어(12)의 회전에 의해 하우징(12)을 통해 공기토출구(13)로 토출됨으로서 실내의 난방이 이루어진다.The present invention as described above detects the amount of carbon monoxide in the waste gas outlet 9 in the process of sucking the air necessary for combustion into the oil burner 4 by the burner motor 1 and the burner motor blower 2. By sensing the sensor 14 to adjust the rpm of the burner motor 1 to adjust the air mixture ratio in the oil burner 4, the ignition transformer 6 to ignite the fuel injected from the nozzle (5) The combustion gas ignited and combusted is discharged to the outside through the chamber 7, the radiator 8, and the waste gas outlet 9.

AlpM (rpm) of the motor 1 is set to about to control the amount of air required for complete combustion.

이상에서 설명한 바와 같은 본 고안은 폐가스중에 함유된 일산화탄소의 량을 감지하여 자동적으로 연소공기 혼합비를 조절하므로 연료의 연소효율을 높여서 난방효율을 향상시키며, 불완전 연소시에 발생되는 일산화탄소의 량을 줄여 줌으로써 쾌적한 주위환경 및 공해방지에 기여하는 이점이 있다.As described above, the present invention senses the amount of carbon monoxide contained in the waste gas and automatically adjusts the combustion air mixing ratio, thereby improving the combustion efficiency of the fuel, thereby improving heating efficiency, and reducing the amount of carbon monoxide generated during incomplete combustion. There is an advantage that contributes to a pleasant environment and pollution prevention.
