Description

팬히터의 기화기내 잔유기름 회수장치Residual oil recovery unit in carburetor of fan heater

본 고안은 팬히터의 기화기에 관한 것으로서, 특히 팬히터가 소화된 이후 기화기내에 남아있는 잔유기름을 기름받이로 회수하므로써 기화기의 초기예열시 기화기내에 남아있는 잔유기름으로 인한 타르의 발생을 억제할 수 있는 팬히터의 기화기내 잔유기름 회수장치에 관한 것이다.The present invention relates to a carburetor of a fan heater, in particular, a fan heater that can suppress the generation of tar due to the residual oil remaining in the carburetor during the initial preheating of the carburetor by recovering the residual oil remaining in the carburetor after the fan heater is digested. It relates to a residual oil recovery device in the vaporizer.

일반적으로, 팬히터에는 연료탱크에서 공급된 연료를 기화시켜 버너로 공급하는 기화기가 장착되어 있다.In general, the fan heater is equipped with a carburetor for vaporizing the fuel supplied from the fuel tank to supply to the burner.

도 2는 일반적인 팬히터의 연료공급계통을 나타낸 도면으로, 연료탱크에서 공급된 연료를 기화시키는 기화기 파이프(10)와, 연료공급관(20)을 통해 상기 기화기 파이프(10)에서 공급된 연료를 버너로 분사시키는 연료공급부(30)로 구성되어 있는데, 상기 연료공급부(30)는 기화된 연료를 버너로 분사시키는 노즐(60)과 ,상기 노즐(60)을 개폐하여 버너로 연료를 공급 또는 차단시키는 니들샤프트(50)가 장착된 솔레노이드밸브(40)로 구성되어 있다.2 is a view illustrating a fuel supply system of a general fan heater, and a vaporizer pipe 10 for vaporizing fuel supplied from a fuel tank and a fuel supplied from the vaporizer pipe 10 through a fuel supply pipe 20 to a burner. It is composed of a fuel supply unit 30 for injecting, the fuel supply unit 30 is a nozzle for injecting the vaporized fuel to the burner, and a needle for supplying or blocking fuel to the burner by opening and closing the nozzle 60 It consists of the solenoid valve 40 with which the shaft 50 was attached.

상기와 같이 구성된 종래의 팬히터에서는, 연료탱크에 저장되어 있는 연료가 기화기 파이프(10)로 공급되면 공급된 연료는 기화기 예열히터(70)에 의해 기화되어 연료공급관(20)을 통해 연료공급부(30)로 공급된다.In the conventional fan heater configured as described above, when the fuel stored in the fuel tank is supplied to the carburetor pipe 10, the supplied fuel is vaporized by the carburetor preheating heater 70 and the fuel supply unit 30 through the fuel supply pipe 20. Is supplied.

기화된 연료가 연료공급부(30)로 공급되면 제어부의 제어신호에 따라 연료를 버너로 분사하는 노즐(60)을 개폐시키는 니들샤프트(50)가 장착된 솔레노이드밸브(40)가 구동되어 연료를 분사하게 된다.When the vaporized fuel is supplied to the fuel supply unit 30, the solenoid valve 40 equipped with the needle shaft 50 for opening and closing the nozzle 60 for injecting fuel to the burner is driven according to the control signal of the controller to inject fuel. Done.

그러나, 상기와 같은 종래의 연료공급계통에서는 팬히터의 소화시 기화기 파이프내에 남아있는 가스가 기화기 파이프내에 잔유하게 됨에 따라 팬히터의 재구동시 상기 잔유기름으로 인해 타르가 발생하여 기화기 파이프와 연료공급부를 연결하는 연료공급관을 막아 버너로의 연료공급이 원활하게 이루어지지 않는다는 문제점이 있었다.However, in the conventional fuel supply system as described above, since gas remaining in the carburetor pipe remains in the carburetor pipe when the fan heater is extinguished, tar is generated due to the residual oil when the fan heater is restarted, thereby connecting the carburetor pipe and the fuel supply unit. There was a problem that the fuel supply to the burner is not smoothly blocked by the fuel supply pipe.

상기와 같은 문제점을 해결하기 위해 종래에는 도 3에 도시된 바와같이 기화기 파이프(10)의 후단에 솔레노이드밸브(40)로 연통되는 별도의 회수관(110)을 설치하여 기화기 파이프(10)내에 남아있는 연료를 회수하였으나, 일반적으로 기화기 파이프(10)가 경사지게 팬히터에 장착되므로 기체상태의 연료만이 회수되고, 액화된 액체상태의 연료는 회수되지 않아 타르의 발생을 효과적으로 억제하지 못한다는 문제점이 있었다.In order to solve the above problems, conventionally, as shown in FIG. 3, a separate recovery pipe 110 connected to the solenoid valve 40 is installed at the rear end of the vaporizer pipe 10 to remain in the vaporizer pipe 10. Although recovering the existing fuel, in general, since the vaporizer pipe 10 is mounted on the fan heater inclined, only the gaseous fuel is recovered, and the liquefied liquid fuel is not recovered, thereby preventing the generation of tar effectively. .

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 팬히터가 소화되면 기화기 파이프의 하부 일측에 형성되어 있는 연료배출구를 통해 배출된 기름을 기름받이로 회송시킴에 따라 기화기 초기예열시 상기 기화기 파이프에 남아있는 잔유기름으로 인한 타르의 발생을 효과적으로 억제할 수 있는 팬히터의 기화기내 잔유기름 회수장치를 제공하는 것을 그 목적으로 한다.Therefore, the present invention was devised to solve the above problems, and when the fan heater is extinguished, the carburetor is initially preheated according to the oil discharged through the fuel outlet formed on the lower side of the carburetor pipe to the oil sump. It is an object of the present invention to provide a residual oil recovery device in a vaporizer of a fan heater which can effectively suppress the generation of tar due to residual oil remaining in a pipe.

상기와 같은 목적을 달성하기 위하여 본 고안은, 팬히터에 있어서, 연료탱크에서 공급된 연료를 기화시키는 기화기의 하부 일측에 형성되어 있으며 상기 기화기내에 잔유하고 있는 기름을 외부로 배출하는 연료배출구와, 상기 연료배출구를 통해 배출된 기름을 기름받이로 회송시키는 연료배출관과, 상기 연료배출관의 상단부에 장착되어 있으며 제어부의 제어신호에 따라 연료배출관을 개방 또는 폐쇄시키는 솔레노이드밸브를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the fan heater, formed on the lower side of the vaporizer for vaporizing the fuel supplied from the fuel tank and the fuel outlet for discharging the oil remaining in the vaporizer to the outside, and A fuel discharge pipe for returning the oil discharged through the fuel discharge port to the sump, and is mounted on the upper end of the fuel discharge pipe, characterized in that it comprises a solenoid valve for opening or closing the fuel discharge pipe in accordance with the control signal of the controller.

이하, 본 고안의 바람직한 일실시에를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in detail.

도 1은 본 고안에 따른 잔유기름 회수장치의 구성을 나타낸 도면으로, 연료탱크에서 공급된 연료를 기화시키는 기화기 파이프(10)의 하부 일측에 상기 기화기 파이프(10)내에 잔유하고 있는 기체 및 엑체 상태의 기름을 배출하기 위한 연료배출구(80)가 형성되어 있고, 상기 연료배출구(80)는 연료배출관(90)을 통해 기름받이에 연결되어 있다.1 is a view showing the configuration of a residual oil recovery apparatus according to the present invention, the gas and liquid state remaining in the vaporizer pipe 10 on the lower side of the vaporizer pipe 10 for vaporizing the fuel supplied from the fuel tank A fuel outlet port 80 for discharging oil of the fuel outlet port 80 is formed, and the fuel outlet port 80 is connected to the oil receiver through the fuel outlet pipe 90.

한편, 상기 연료배출관(90)의 상단부에는 팬히터 내부에 장착되어 있는 제어부의 제어신호에 따라 연료배출관(90)을 개방 또는 폐쇄시켜 기화기 파이프(10)내에 남아있는 기름을 기름받이로 배출시키는 솔레노이드밸브(100)가 장착되어 있다.On the other hand, the solenoid valve for discharging the oil remaining in the carburetor pipe 10 to the sump by opening or closing the fuel discharge pipe 90 in accordance with the control signal of the controller mounted inside the fan heater at the upper end of the fuel discharge pipe (90). 100 is mounted.

또한, 대부분의 기화기 파이프(10)가 팬히터 내부에 경사지게 장착됨에 따라 상기 연료배출구(80)는 기화기 파이프(10)의 하부 경사면 단부에 형성하는 것이 바람직하다.In addition, as most of the vaporizer pipe 10 is mounted inclined in the fan heater, the fuel outlet 80 is preferably formed at the lower inclined end of the vaporizer pipe 10.

상기와 같이 구성된 본 고안에 따른 기화기내 잔유기름 회수장치에서는, 팬히터가 소화되면 솔레노이드밸브(100)가 오프(off)되어 연료배출관(90)을 개방하게 된다. 따라서, 기화기 파이프(10)내에 잔유하고 있던 기체 및 액체 상태의 기름이 연료배출구(80)와 연료배출관(90)을 통해 기름받이로 회수된다.In the residual oil recovery apparatus in the vaporizer according to the present invention configured as described above, when the fan heater is extinguished, the solenoid valve 100 is turned off to open the fuel discharge pipe 90. Accordingly, gas and liquid oil remaining in the vaporizer pipe 10 are recovered to the sump via the fuel discharge port 80 and the fuel discharge pipe 90.

한편, 팬히터가 재구동되면 상기 솔레노이드밸브(100)가 온(of)되어 연료배출관(90)을 폐쇄시킨다. 따라서, 기화기 파이프(10)로 공급된 기름은 기화기 예열히터(70)에 의해 기화되어 연료공급관(20)을 통해 연료공급부(30)로 공급된다.On the other hand, when the fan heater is driven again, the solenoid valve 100 is turned on to close the fuel discharge pipe 90. Accordingly, the oil supplied to the vaporizer pipe 10 is vaporized by the vaporizer preheater 70 and supplied to the fuel supply unit 30 through the fuel supply pipe 20.

상기와 같이 본 고안은, 핸히터가 소화되면 기화기 파이프에 남아있는 기름을 상기 기화기 파이프의 하부 일측에 형성되어 있는 연료배출구를 통해 회수하여 기름받이로 회송시킴에 따라 기화기 초기예열시 기화기 파이프내에 남아있는 잔유기름으로 인한 타르의 발생을 억제할 수 있다. 따라서, 기화기 파이프와 연료공급부를 연결하는 연료공급관의 폐쇄를 방지할 수 있어 버너를 기름을 원활하게 공급할 수 있다.As described above, when the heater is extinguished, the oil remaining in the carburetor pipe is recovered through the fuel outlet formed at the lower side of the carburetor pipe and returned to the drip tray, so that it remains in the carburetor pipe during initial preheating. It is possible to suppress the generation of tar due to residual oil. Therefore, it is possible to prevent the closing of the fuel supply pipe connecting the carburetor pipe and the fuel supply unit, thereby smoothly supplying the burner with oil.

본 고안은 도면에 도시된 일실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에 통상의 지식을 지닌자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 고안의 진정한 기술적 보호범위는 첨부된 실용신안등록청구의 범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
