본 고안은 팬히터의 연료분사소음 방지 유도관에 관한 것으로 특히 연소시에 기화된 연료를 노즐로 부터 연소기에 분사실킬때 발생되는 분사소음을 외부로부터 공기가 형성시킨 유도관을 통해 차폐시킴으로써 연료분사시 발생되는 분사소음을 최대한으로 방지할수 있도록 한 팬히터의 연료분사 소음방지 유도관에 관한것이다.The present invention relates to an induction pipe for preventing the fuel injection noise of a fan heater. In particular, the injection noise generated when the vaporized fuel is injected into the combustor from the nozzle during combustion is shielded through an induction pipe formed by air from the outside. It relates to a fuel injection noise prevention induction pipe of a fan heater to prevent the injection noise generated to the maximum.
종래의 팬히터에서는 기화된 연료를 분사시키는 노즐의 근접 부위에 외부의 공기가 유입되는 외부공기유입구가 형성되어 있어서 연소시에 기화기에서 기화된 연료를 연소기에 노즐로 분사시킬때 분사소음이 발생되고 이 분사소음은 상기 외부공기 유입구를 통해 직접 방출되므로 연소시에 분사소음이 크게 발생되는 문제점을 가지고 있었다.In the conventional fan heater, an external air inlet is formed in the vicinity of the nozzle for injecting the vaporized fuel, so that the injection noise is generated when the vaporized fuel is injected into the combustor through the nozzle at the time of combustion. Since the injection noise is directly discharged through the external air inlet, injection noise is greatly generated during combustion.
본 고안은 상기와 같은 문제점을 해결하기 위하여 외부 공기 유입구에 길에 연장시킨 유도관을 통해 유입되게하고 분사시 발생되는 분사소음은 이를 통해 차폐 및 소멸시키도록 함으로써 분사소음을 최대로 방지하도록 한 것이다.In order to solve the above problems, the present invention allows the outside air inlet to be introduced through the induction pipe extending on the road and the injection noise generated during the injection is shielded and extinguished through this to prevent the injection noise to the maximum. .
이하 첨부된 도면에 의거 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도 및 제2도에 도시한 바와같이 전면판(1)에 다수개의 외부공기유입공(2)이 천설되고 후판(3)일측에 외부공기유입구(4)가 형성된 연소통(5)내부에는 기화연료와 외부공기가 혼합된 가스를 연소시키는 연소기(6)가 지지체(7)에 의해 설치되고 이 지지체(7)의 측면에는 상부에 열전도관(8)과 내부에 전열히터(9), 연료분사관(10)이 내장되고 일측에 솔레노이드밸브(11)와 연동되게되는 노즐(12)을 상기 연소통(5)에 관통설치시킨 기와기(13)를 설치시켜서 된 것에 있어서, 상기 외부공기유입구(4)와 연소통(5)의 사이에 소정규격을 갖는 유도관(14)을 길게 연장되게 형성시켜서 된 것이다.As shown in FIGS. 1 and 2, inside the combustion cylinder 5 in which a plurality of external air inlet holes 2 are laid on the front plate 1 and an external air inlet 4 is formed on one side of the rear plate 3. There is a combustor 6 which burns gas mixed with vaporized fuel and external air by means of a support 7, and on the side of the support 7 there is a heat conduction tube 8 at the top and an electric heater 9 inside. The external air in which the fuel injection pipe 10 has a built-in tiler 13 through which the nozzle 12, which is interlocked with the solenoid valve 11, is installed on one side of the combustion cylinder 5, is provided. The induction pipe 14 having a predetermined standard is formed between the inlet port 4 and the combustion cylinder 5 to extend for a long time.
상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
팬히터의 전원을 온시키면 기화기(13)의 내부에 내장된 전열 히터(9)가 구동하면서 기화기(13)를 가열시킴과 동시에 연료펌프(도시되지 않음)가 가동하면서 펌핑된 연료를 연료분사관(10)을 통해 솔레노이드밸브(11)의 구동에 따라 조절된 상태로 노즐(12)을 통하여 기화기(13)에서 기화된 연료로 연소기(6)에 분사시키고 연소기(6)에서는 외부의 공기를 연소통(5)의 후판(3)에 길게 형성된 유도관(14)의 외부공기 유입구(4)로 유입하여 기화된 분사연료와 유입된 공기를 혼합하여 1차 연소시키게 되고, 연소기(6)에서는 연소통(5)의 전면에 형성된 다수개의 외부공기유입공(4)를 통해 외부공기를 받아 2차연소시켜 팬히터를 가열시켜주게 되는 것이다. 이와 같이 팬히터를 가열시키는 과정에서 노즐(12)로 부터 연소기(6)에 기화된 연료를 분사시킬때 분사소음이 발생되게 되는데 이 분사소음은 상기 외부공기유입구(4)상에 길게 연장형성시킨 유도관(14)에 의하여 일단 외부와 차폐시켜 주게되어 분사소음이 억제되는 동시에 유도관(14)을 통해서 빠져 나가는 소음은 길게 연장형성된 유도관(14)내에서 소멸되게 되므로 분사시 발생되는 소음이 최대로 방지시킬 수 있게 되는 것이다.When the fan heater is turned on, the electric heater 9 built in the vaporizer 13 is driven to heat the vaporizer 13 and at the same time the fuel pump (not shown) is operated to pump the fuel pumped into the fuel injection pipe ( 10 is injected to the combustor 6 with the fuel vaporized from the vaporizer 13 through the nozzle 12 in a state adjusted according to the operation of the solenoid valve 11 through the nozzle 12, the external air is injected into the combustor 6 (5) flows into the external air inlet (4) of the induction pipe (14) long formed in the rear plate (3) to mix the first injection of the vaporized injection fuel and the air, the combustor (6) in the combustion cylinder It receives secondary air through a plurality of external air inlet holes (4) formed on the front of (5) to heat the fan heater by secondary combustion. In the process of heating the fan heater as described above, injection noise is generated when injecting the vaporized fuel from the nozzle 12 to the combustor 6. The injection noise extends to the external air inlet 4. Once the pipe 14 is shielded from the outside and the injection noise is suppressed and the noise exiting through the induction pipe 14 is extinguished in the induction pipe 14 formed long, the noise generated during the injection is maximized. It will be possible to prevent.
이상에서 설명한 바와같이 본 고안은 기화된 연료를 분사 시키는 노즐의 일측부위에 외부공기유입구와 연통되는 길게 연장된 유도관을 형성시켜 연료분사시 발생되는 분사소음을 외부와 차폐시켜주는 동시에 유도관을 통해 소음을 소멸시켜 주게 되므로 소음이 최대로 방지된 팬히터를 제공해줄 수 있는 효과가 있는 것이다.As described above, the present invention forms an elongated induction pipe communicating with the external air inlet at one side of the nozzle for injecting the vaporized fuel to shield the injection noise generated during the fuel injection from the outside and at the same time. Since the noise is extinguished, the fan heater can be provided with the maximum noise.
