An air purifier 20 is mounted on one side of a fan heater 110. The air purifier 20 includes an air inlet 22 And an inflow pipe 26 into which the unburned gas stagnated in the oil combustion section 24 flows and the indoor air and the unburned gas through the air intake port 22 and the inflow pipe 26 to the air cleaner And a dust collecting plate 32 for purifying indoor air and unburned gas sucked into the air purifier fan 28 and discharging the cleaned indoor air through the air clean outlet 30 .
한편, 팬히터(110)의 저면에는 오일연소부(24)에서 연소되는 연료의 연소열에 의해 가열된 공기를 실내로 토출하는 온풍토출구(34)가 형성되어 있으며, 오일연소부(24)의 후방에는 오일연소부(24)에서 연소되는 연료의 연소열에 의해 가열된 공기를 실내로 배출하는 송풍팬(36)이 장착되어 있다.On the bottom surface of the fan heater 110 is formed a hot air discharge port 34 for discharging the air heated by the combustion heat of the fuel burned in the oil combustion section 24 to the room, And an air blowing fan 36 for discharging the air heated by the combustion heat of the fuel burned in the oil burning section 24 to the room.
도2는 도1에 도시된 팬히터의 제어장치를 개략적으로 나타낸 블럭도로, 팬히터(110)를 구동시키는 점화스위치(50)가 제어부(60)에 접속되어 있으며, 제어부(60)는 점화스위치(50)의 스위칭 상태에 따라 전자펌프(12), 공기청정기팬(28)과 송풍팬(36) 및 점화트랜스(40)의 구동을 제어한다.2 is a block diagram schematically showing the control device of the fan heater shown in Fig. 1.

다음에는 상기와 같이 구성된 팬히터에 적용되는 본 발명에 따른 팬히터의 석유냄새 제거방법을 도3을 참조하여 상세히 설명한다.Next, a method of removing the petroleum odor of a fan heater according to the present invention applied to the fan heater constructed as above will be described in detail with reference to FIG.
사용자가 팬히터(110)를 구동시키기 위하여 점화스위치(50)를 온시키면(101), 제어부(60)는 전자펌프(12)를 구동시켜 연료탱크에 저장되어 있는 액체연료를 오일연소부(24)로 공급하는 동시에 점화트랜스(40)를 구동하여 오일연소부(24)로 공급된 기화가스를 착화시킨다(102).When the user turns on the ignition switch 50 to drive the fan heater 110, the control unit 60 drives the electromagnetic pump 12 to drive the liquid fuel stored in the fuel tank to the oil burner 24, And the ignition transformer 40 is driven to ignite the vaporized gas supplied to the oil combustion unit 24 (102).
이와 같이 오일연소부(24)로 공급된 기화가스가 착화되면(103), 제어부(60)는 오일연소부(24)내에 정체하고 있는 미연소 가스를 정화시키기 위해 공기청정기팬(28)을 구동한다. 따라서, 유입관(26)을 통해 흡입된 미연소 가스는 공기청정기(20)의 집진판(32)에 의해 정화되어 공기청정토출구(30)를 통해 실내로 배출된다(104).When the vaporized gas supplied to the oil burner 24 is ignited in step 103, the controller 60 drives the air cleaner fan 28 to purge the unburnt gas stagnated in the oil burner 24 do. Accordingly, the unburned gas sucked through the inflow pipe 26 is purified by the dust collecting plate 32 of the air cleaner 20 and discharged to the room through the air clean discharge opening 30 (104).
또한, 제어부(60)는 오일연소부(24)에서 연소되는 연료의 연소열에 의해 가열된 공기를 실내로 배출하기 위하여 송풍팬(36)을 동작시키는데, 이와 같이 송풍팬(36)이 구동되면 가열된 공기가 온풍토출구(34)를 통해 실내로 배출됨에 따라 실내의 난방작용이 이루어진다(105).The control unit 60 operates the blowing fan 36 to discharge the air heated by the combustion heat of the fuel burned in the oil burning unit 24 to the room. When the blowing fan 36 is driven, And the indoor air is heated (105) as the air is discharged to the room through the hot air discharge port (34).
한편, 제어부(60)는 기설정된 소정의 시간(약10분)이 경과하면 팬히터(110)의 초기착화시 발생된 미연소 가스의 공기청정기(20)에 의해 모두 정화된 것으로 판단하여 공기청정기팬(28)의 구동을 정지시키고(107), 송풍팬(36)만 지속적으로 동작시켜 온풍토출구(34)를 통해 가열된 공기를 실내로 배출하는 난방모드를 수행한다(108).When the predetermined time (about 10 minutes) elapses, the controller 60 determines that the unburned gas generated during the initial ignition of the fan heater 110 has been completely cleaned by the air cleaner 20, The driving of the air conditioner 28 is stopped 107 and only the air blowing fan 36 is continuously operated to perform the heating mode for discharging the heated air through the hot air discharge port 34 to the room.
또한, 제어부(60)는 팬히터(110)의 난방모드 수행중에 팬히터(110)의 점화스위치(50)가 오프되면(109), 전자펌프(12)의 구동을 중지시켜 연료의 공급을 차단하고(110), 공기청정기팬(28)을 구동시켜 오일연소부(24)에 남아있는 미연소 가스를 유입관(26)을 통해 공기청정기(20)의 내부로 흡입한다(111).When the ignition switch 50 of the fan heater 110 is turned off (109) during the heating mode of the fan heater 110, the control unit 60 stops the driving of the electromagnetic pump 12 to interrupt the supply of the fuel And the air cleaner fan 28 is driven to suck the unburned gas remaining in the oil combustion unit 24 through the inflow pipe 26 into the air cleaner 20 (111).
흡입된 미연소 가스가 집진판(32)을 통과하며 정화되어 공기청정토출구(30)를 통해 배출됨에 따라 미연소 가스의 배출로 인한 실내공기의 오염은 방지된다(111). 이와 같이 기설정된 소정의 시간동안(약5분) 미연소 가스의 정화동작을 수행한 후, 제어부(60)는 공기청정기팬(28)의 구동을 중지시킨다(112).As the unburned gas is passed through the dust collecting plate 32 and is purified and discharged through the air clean outlet 30, contamination of the room air due to discharge of the unburned gas is prevented 111. After performing the unburned gas purge operation for the preset predetermined time (about 5 minutes), the controller 60 stops driving the air purifier fan 28 (112).
상기와 같이 본 발명은, 팬히터의 초기착화 및 연소중지시에 발생되는 미연소 가스를 공기정화기를 통해 정화시켜 실내로 배출함에 따라 미연소 가스의 배출로 인한 석유냄새의 발생을 방지할 수 있다. 따라서, 사용자에게 보다 쾌적한 실내환경을 제공할 수 있다.As described above, according to the present invention, the unburned gas generated at the time of initial ignition of the fan heater and at the time of stopping combustion is purified through the air purifier and discharged to the room, so that the generation of petroleum odor due to discharge of unburned gas can be prevented. Therefore, a more comfortable indoor environment can be provided to the user.
