본 발명은 가스렌지용 버너헤드에 관한 것으로서, 보다 상세하게는 화염공을 통해 외부의 역풍이 가스분출공으로 유입되는 것을 차단함으로써 혼합가스의 역화 발생을 방지할 수 있도록 하는 동시에 화염공으로 분출되는 혼합가스의 경로를 길게 형성하여 혼합가스가 보다 잘 혼합된 상태에서 화염공으로 분출되도록 함으로써 화염 형성이 양호하게 되도록 하는 가스렌지용 버너헤드에 관한 것이다.The present invention relates to a burner head for a gas stove, and more particularly, a mixed gas ejected into a flame hole at the same time to prevent backfire of the mixed gas by preventing external backwind from flowing into the gas ejection hole through the flame hole. It relates to a burner head for a gas stove to form a long path so that the mixture gas is ejected to the flame hole in a better mixed state to improve the flame formation.

일반적으로 가스버너는 가스연료를 효율적으로 연소시켜 열 및 고온을 이용하기 위한 장치로서, 가정용 풍로에 사용되는 소규모의 것에서부터 화력발전소의 보일러에 쓰이는 대규모의 공업용 버너에 이르기까지 여러 가지 형식이 있으나 연료와 공기를 혼합시키는 방식으로서 예혼합형(豫混合型)과 확산형(擴散型)의 2가지로 대별되며, 가스렌지는 이러한 가스버너를 이용한 가전제품을 말하는 것이다. In general, gas burners are devices for efficiently burning gas fuel to use heat and high temperature, and there are various types of fuels, ranging from small scales used in home furnaces to large scale industrial burners used in boilers of thermal power plants. As a method of mixing the air and air, it is classified into two types, a premixed type and a diffused type, and a gas stove refers to a home appliance using such a gas burner.

그리고, 일반적인 가스렌지는 중앙에 혼합기관로와 연결되는 가스분출공이 형성되고 상면 테두리 전체를 따라 화염공이 형성된 버너본체와, 이 버너본체의 상면을 덮어씌워 가스분출공을 통해 상향 분출된 가스가 화염공을 향해 방사상으로 퍼지도록 하는 버너헤드를 포함하여 구성된다.In addition, a general gas stove has a gas ejection hole connected to the mixing engine at the center and a burner body formed with flame holes along the entire upper edge thereof, and the gas ejected upward through the gas ejection hole by covering the upper surface of the burner body is flamed. And a burner head to radially spread toward the ball.

일례로 가스렌지의 버너본체(10)는 도 1에서 나타내듯이, 중앙에 가스분출공(12)이 관통 형성된 원판 형상으로, 그 상면 외주에는 테두리 전체를 따라 일정하게 형성된 복수의 화염공(14)이 형성되어 있으며, 이들 화염공 중 소정의 화염 공(14) 인접부에는 열전대(16)가 상향 돌출된 상태로 설치되어 있다.As an example, the burner body 10 of the gas stove has a disc shape in which a gas ejection hole 12 penetrates at the center thereof, and a plurality of flame holes 14 are formed uniformly along the entire rim of the upper surface outer periphery thereof. Is formed, and the thermocouple 16 is provided in the state which protrudes upward in the predetermined flame ball 14 adjacent part among these flame holes.

그리고, 도 2 및 도 3에서 나타내듯이, 종래 기술의 버너헤드(20)는 버너본체(10)의 상면에 얹혀지는 원판 형상으로, 그 저면은 상기 버너본체(10)의 상방이 개방된 화염공(14) 상면을 덮어씌워 사각형상의 통로를 형성시키도록 되어 있다. 2 and 3, the burner head 20 of the prior art has a disc shape that is placed on the upper surface of the burner body 10, the bottom surface of which is a flame hole in which the burner body 10 is opened upward. (14) The upper surface is covered to form a rectangular passage.

이러한 구성의 가스렌지는 가스밸브를 열어 가스를 가스분출공(12)을 통해 버너본체(10)의 상방으로 분출시키면 이 분출압에 의해 외부공기가 흡입되면서 가스와 혼합되어 혼합가스로 변하게 되고 이 혼합가스는 계속해서 상향 분출되다가 버너본체(10) 상면에 덮여있는 버너헤드(20)의 저면에 부딪친 후 화염공(14)을 향해 방사상으로 퍼지면서 이 화염공(14)을 통과하여 버너본체(10)의 외부로 분출되는 순간 점화플러그(미도시)의 스파크에 의해 화염으로 화하게 되는 것이다. The gas stove having such a configuration opens a gas valve and ejects the gas upwards through the gas ejection hole 12 to the burner main body 10, whereby external air is sucked by the ejection pressure, mixed with the gas, and changed into a mixed gas. The mixed gas is continuously blown upward and hits the bottom of the burner head 20 covered on the upper surface of the burner body 10, and then radially spreads toward the flame hole 14 and passes through the flame hole 14 to burner body ( As soon as it is ejected to the outside of 10), the spark is sparked by a spark of a spark plug (not shown).

그러나, 이러한 종래 기술의 버너헤드(20)는 그 저면이 편평하게 형성되어 있어 화염공(14) 외부와 곧바로 연통되어 있기 때문에 가스분출공(12)을 통해 화염공(14)으로 분출되는 혼합가스가 외부의 역풍에 의해 역화가 발생되는 문제점이 있었고, 또한, 혼합가스의 배출경로가 버너헤드(20)의 저면에서 화염공(14)으로 곧바로 이어지는 직선 경로여서 그만큼 혼합가스가 혼합되는 시간이 충분하지 않기 때문에 화염공(14)으로 분출되는 혼합가스의 화염 형성이 양호하지 못하게 되는 등의 문제점을 갖고 있었다. However, the burner head 20 according to the related art has a flat bottom surface and is directly in communication with the outside of the flame hole 14, so that the mixed gas ejected into the flame hole 14 through the gas blowing hole 12. There was a problem that backfire occurred due to external backwind, and the discharge path of the mixed gas was a straight path leading directly to the flame hole 14 from the bottom of the burner head 20, so that the time for mixing the mixed gas was sufficient. Because of this problem, there was a problem that the flame formation of the mixed gas ejected into the flame hole 14 was not good.

본 발명은 이러한 문제점을 해결하기 위해서 안출된 것으로서, 화염공을 통해 외부의 역풍이 가스분출공으로 유입되는 것을 차단함으로써 혼합가스의 역화 발 생을 방지할 수 있도록 하는 동시에 화염공으로 분출되는 혼합가스의 경로를 길게 형성하여 혼합가스가 보다 잘 혼합된 상태에서 화염공으로 분출되도록 함으로써 화염 형성이 양호하게 되도록 하는 가스렌지용 버너헤드를 제공하는데 그 목적이 있다. The present invention has been made in order to solve this problem, by preventing the external backwind flows into the gas ejection hole through the flame hole to prevent the backfire of the mixed gas and at the same time the path of the mixed gas ejected into the flame hole It is an object of the present invention to provide a burner head for a gas stove to form a long by making the mixed gas is ejected to the flame hole in a better mixed state to improve the flame formation.

이와 같은 상기 목적을 달성하기 위한 본 발명의 가스렌지용 버너헤드는 중앙에 가스분출공이 형성되고 이 가스분출공 주위가 하방으로 경사진 본체경사면을 가지며 상면 외주 테두리 전체를 따라 화염공이 형성된 버너본체의 상면에 얹혀지는 가스렌지용 버너헤드에 있어서, 상기 버너헤드의 저면에 화염공과 최소한 동일 높이가 되도록 하방으로 돌출되어 화염공으로부터의 역풍 유입을 차단하는 역풍차단벽이 형성된 것을 특징으로 한다.Gas burner burner head of the present invention for achieving the above object has a gas inlet hole is formed in the center of the burner body has a body inclined surface inclined downward and the flame hole along the entire outer peripheral edge In the burner head for a gas stove mounted on the upper surface, characterized in that the bottom of the burner head is projected downward so as to be at least the same height as the flame hole is formed with a reverse wind blocking wall for blocking the inflow of the reverse wind from the flame hole.
