More specifically, the exhaust gas discharged through the exhaust pipe can be prevented from being re-introduced into the supply pipe to improve combustion efficiency. The present invention relates to a radiator exhaust pipe.

일반적으로 난방기는 동절기 등에서 쾌적한 실내온도를 유지하기 위해 열을 공급하여 실내의 기온을 높이는 장치로서, 사용되는 열원에 따라 전기 난방기, 증기 난방기, 온수 난방기, 온풍 난방기 등으로 나누어진다.In general, a heater is a device that increases the temperature of the room by supplying heat to maintain a comfortable room temperature in winter, etc., is divided into electric heaters, steam heaters, hot water heaters, hot air heaters and the like according to the heat source used.

온풍 난방기는 실내에 고온풍을 불어 넣어 난방하는 장치로서, 전원스위치를 온시키면 버너(2)가 착화되어 연소실(4) 내부에서 연소되고, 이 연소열에 의해 연소실(4)과 열교환기(6)가 가열된다. 이러한 상태에서 송풍기구(10)를 작동시키면 연소실(4)과 열교환기(6)를 통과하는 공기가 가열되고, 이 가열된 공기는 송풍그릴(8)을 통해 실내로 공급된다.A warm air heater is a device that blows high temperature air into a room and heats it. When the power switch is turned on, the burner 2 is ignited and combusted in the combustion chamber 4, and the combustion heat causes the combustion chamber 4 and the heat exchanger 6 to heat up. Is heated. When the blower device 10 is operated in this state, the air passing through the combustion chamber 4 and the heat exchanger 6 is heated, and the heated air is supplied to the room through the blower grill 8.

이때, 외부공기가 급기관(12)을 통해 버너(2)로 공급되면 연료와 혼합되어 연소실(6)에서 연소가 이루어지고, 연소가 끝난 배기가스는 열교환기(6)를 거쳐 배기관(14)을 통해 외부로 배출되도록 이루어진다.At this time, when external air is supplied to the burner 2 through the air supply pipe 12, the fuel is mixed with the fuel to combust in the combustion chamber 6, and the exhaust gas after the combustion is exhausted through the heat exchanger 6 to the exhaust pipe 14.
