Description

캐비넷 히터의 역화방지용 버너Burner to prevent backfire of cabinet heater

본 고안은 캐비넷 히터의 역화방지용 버너에 관한 것으로서, 구체적으로는 캐비넷 히터의 세라믹 버너 하측에 혼합관의 1차공기투입구의 전방을 막는 역화방지판을 설치하여 1차공기투입구로의 가스의 유입을 막아 역화를 방지하도록 하는 캐비넷 히터의 역화방지용 버너에 관한 것이다.The present invention relates to a burner for preventing the flashback of the cabinet heater, and specifically, to prevent the inflow of gas into the primary air inlet by installing a flashback prevention plate that blocks the front of the primary air inlet of the mixing pipe under the ceramic burner of the cabinet heater. It relates to a burner for preventing backfire of a cabinet heater to prevent backfire by preventing it.

일반적으로, 캐비넷 히터는 제4도에 도시한 바와 같이 전면판넬(2) 중앙에는 안전망(4)을 설치하고, 이 안전망(4)의 후방에는 세라믹 버너(6)를 장착하는 것이다. 상기 세라믹 버너(6) 하측에는 가스공급관(11)의 노즐(12)이 삽입되는 혼합관(8)을 설치하며, 이 혼합관(8)의 전방에는 1차공기를 투입하기 위한 1차공기투입구(10)를 설치하는 한편, 상기 세라믹 버너(6) 하측 전방에는 조작부(14)에서 이그나이터와 연결된 점화플러그(16)가 설치되어 진다.In general, as shown in FIG. 4, the cabinet heater is provided with a safety net 4 in the center of the front panel 2 and a ceramic burner 6 in the rear of the safety net 4. A mixing pipe 8 into which the nozzle 12 of the gas supply pipe 11 is inserted is provided below the ceramic burner 6, and a primary air inlet for introducing primary air into the front of the mixing pipe 8. While installing (10), the ignition plug (16) connected to the igniter in the operation unit (14) is installed at the lower front side of the ceramic burner (6).

이와 같이 구성되는 종래의 캐비넷 히터(1)의 사용연료는 부탄가스를 사용하게 되는 데, 부탄가스는 일반공기의 하중보다 무거워 조작부(14)에서 점화버튼을 동작시킬 경우에 가스통과 연결된 기구콕크가 열린 후 세라믹 버너(6)의 하측에 점화플러그(16)에서 불꽃이 튀어 세라믹 버너(6)를 착화시켜 주는 것이나, 이때 부탄가스는 점화플러그(16)에서 불꽃이 튀기전에 세라믹 버너(6)의 염공을 통해 분출된 상태로서 전면판넬(2)의 세라믹 버너(6) 하측의 공간부(3) 및 전면판넬(2)과 세라믹 버너(6)의 하측 틈새로 가라앉게 되어 세라믹 버너(6) 하측에 형성된 혼합관(8)의 1차공기투입구(10)로 부탄가스가 유입되어 점화플러그(16)의 착화와 동시에 역화현상이 발생되는 단점이 있었다.The fuel used in the conventional cabinet heater 1 configured as described above uses butane gas, but the butane gas is heavier than the load of general air, so that when the ignition button is operated on the operation unit 14, a mechanism cock connected to the gas cylinder is used. After opening, sparks are emitted from the spark plug 16 under the ceramic burner 6 to ignite the ceramic burner 6, but at this time, butane gas is discharged from the ceramic burner 6 before the spark is blown from the spark plug 16. It is ejected through the flame hole and sinks to the space portion 3 below the ceramic burner 6 of the front panel 2 and to the lower gap between the front panel 2 and the ceramic burner 6, thereby lowering the ceramic burner 6. Butane gas flowed into the primary air inlet 10 of the mixing tube 8 formed in the ignition of the spark plug 16 and at the same time there was a disadvantage that the backfire occurs.

이에, 본 고안은 상기와 같은 문제점을 해소하기 위한 것으로서, 본 고안의 목적은 세라믹 버너 하측에 형성된 혼합관의 1차공기투입구의 전면에 역화방지판을 설치하여 세라믹 버너의 점화 전 분출되는 부탄가스가 혼합관의 1차공기투입구로의 유입을 막아 역화를 방지하는 캐비넷 히터의 역화방지용 버너를 제공하는 것이다.Accordingly, the present invention is to solve the above problems, the object of the present invention is to install a flashback prevention plate on the front of the primary air inlet of the mixing tube formed on the bottom of the ceramic burner butane gas is ejected before ignition of the ceramic burner It is to provide a burner for preventing the back of the cabinet heater to prevent backfire by preventing the inlet to the primary air inlet of the mixing pipe.

상기와 같은 목적을 달성하기 위하여 본 고안은 전면에는 중앙에 안전망이 형성된 전면판넬을 설치하고, 상기 전면판넬 후방에는 세라믹 버너를 설치하여 세라믹 버너의 하측에는 전방에 1차공기투입구가 형성된 혼합관이 설치된 캐비넷 히터에 있어서, 상기 혼합관에 형성된 1차공기투입구의 전방으로 역화방지판을 설치하고, 이 역화방지판을 세라믹 버너의 하측에 형성된 다수의 홀에 스크류로 체결하여 고정하는 것을 특징으로 하는 것이다.In order to achieve the above object, the present invention is provided with a front panel having a safety net formed in the center of the front panel, a ceramic burner installed at the rear of the front panel, and a mixing pipe having a primary air inlet formed at the front side of the ceramic burner. In a cabinet heater provided, a flashback prevention plate is installed in front of the primary air inlet formed in the mixing pipe, and the flashback prevention plate is screwed into and fixed to a plurality of holes formed in the lower side of the ceramic burner. will be.

(6) The lower connection assembly is the same as the above, and shows a state in which the bent portion 26 is formed by bending the lower portion of the flashback prevention plate 20 forward.

상기와 같이 구성되어진 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention is configured as described above are as follows.

제1도 및 제2도에 도시된 바와 같이 캐비넷 히터(1)의 전면판넬(2) 후방에 세라믹 버너(6)를 장착하기 전 세라믹 버너(6)의 하측에 역화방지판(20)을 설치하여 캐비넷 히터(1) 상측에 조작부(14)에서 가스공급관(11)과 연결된 기구콕크를 열어주면 상기 세라믹 버너(6)의 염공에서 부탄가스가 밖으로 분출된 후, 점화버튼과 연결된 점화플러그(16)에서 불꽃을 튀겨 부탄가스를 착화시키게 된다. 이때 상기 세라믹 버너(6)에서 분출되는 부탄가스는 공기보다 무거워 점화플러그(16)의 착화전에 점화플러그(16)가 삽입되는 전면판넬(2)의 공간부(3) 및 전면판넬(2)과 세라믹 버너(6)의 틈새를 통해 아래로 가라앉게 되는 데, 이때 세라믹 버너(6) 하측에 설치된 역화방지판(20)으로 인하여 1차공기투입구(10)로 부탄가스가 유입되는 것이 방지되어 지는 것이다.As shown in FIGS. 1 and 2, a flashback prevention plate 20 is installed below the ceramic burner 6 before the ceramic burner 6 is mounted behind the front panel 2 of the cabinet heater 1. By opening the mechanism cock connected to the gas supply pipe 11 in the operation unit 14 above the cabinet heater 1, butane gas is blown out from the salt hole of the ceramic burner 6, and then the spark plug 16 connected to the ignition button 16. The flame is splashed at) to ignite butane gas. At this time, butane gas ejected from the ceramic burner 6 is heavier than air, and thus the space 3 and the front panel 2 of the front panel 2 into which the ignition plug 16 is inserted before the ignition plug 16 is ignited. It sinks down through the gap of the ceramic burner (6), but the butane gas is prevented from flowing into the primary air inlet (10) by the flashback prevention plate 20 installed below the ceramic burner (6). will be.

즉 세라믹 버너(6)의 염공으로 분출된 부탄가스는 착화되기 전에 분출되어지므로 이 분출된 가스는 하방으로 가라앉게 되고, 하방으로 가라앉은 부탄가스는 역화방지판(20)을 타고 아래로 흘러내리게 되므로 세라믹 버너(6)의 하측에 장착된 혼합관(8)의 1차공기투입구(10)의 유입을 막을 수 있는 것이다.That is, butane gas ejected by the flame holes of the ceramic burner 6 is ejected before being ignited, so that the ejected gas is sunk downward, and the butane gas sunk downward is allowed to flow down through the flashback preventing plate 20. Therefore, it is possible to prevent the inflow of the primary air inlet 10 of the mixing tube (8) mounted on the lower side of the ceramic burner (6).

또한 제3도에 도시한 바와 같이 상기 역화방지판(20)의 하부를 전방으로 돌출시켜 절곡부(26)를 형성하므로서 절곡부(26)의 배면과 혼합관(8)의 1차공기투입구(10) 사이의 폭을 확장하여 세라믹 버너(6)의 연소시 공기투입을 원활히 할 수 있는 것이다.In addition, as shown in FIG. 3, the lower portion of the flashback preventing plate 20 protrudes forward to form the bent portion 26, so that the rear surface of the bent portion 26 and the primary air inlet of the mixing tube 8 ( 10) by expanding the width between the can be smoothly the air input during the combustion of the ceramic burner (6).

상술한 바와 같이 본 고안은, 세라믹 버너의 하측 혼합관의 전방에 천공된 1차공기투입구로 착화전 부탄가스의 유입을 막는 역화방지판을 설치하므로서 점화플러그의 착화시 역화를 방지하는 효과가 있는 것이다.As described above, the present invention has an effect of preventing backfire during ignition of the spark plug by installing a flashback prevention plate which prevents inflow of butane gas before ignition to the primary air inlet perforated in front of the lower mixing pipe of the ceramic burner. will be.
