【考案の詳細な説明】
本考案はガス燃焼器具例えば風呂釜などに用いて有効な
ガスバーナに関するものである。[Detailed Description of the Invention] The present invention relates to a gas burner that is effective for use in gas combustion appliances such as bathtubs.
従来都市ガスと天然ガスのように燃焼速度の異なる燃料
ガスを同一のガスバーナで燃焼しうるようにしたガスバ
ーナいわゆるユニバーサル化されたガスバーナに関して
は種々検討工夫が行なわれてきた。Conventionally, various studies have been made regarding so-called universal gas burners, which are capable of burning fuel gases with different combustion speeds, such as city gas and natural gas, in the same gas burner.
例えば天然ガスの燃焼時に最も問題となるリフティング
を防止するために主燃焼炎の基端部附近に補助火炎を形
式して保炎しうるようにした炎孔構造を有するガスバー
ナ、あるいは燃焼速度が速い都市ガスの場合には逆火を
防止するために主炎孔を2段炎孔形状に加工したガスバ
ーナなどが開発されている。For example, in order to prevent lifting, which is the most problematic issue when burning natural gas, there is a gas burner with a flame hole structure in which an auxiliary flame is placed near the base of the main combustion flame to stabilize the flame, or a gas burner with a high combustion speed. In the case of city gas, gas burners have been developed in which the main flame hole is shaped into a two-stage flame hole shape in order to prevent backfire.

スバーナは何れも構造が複雑であり製造加工に困難をと
もないしたがってコストも高くなるという欠点があった
。However, both the flame-holding type gas burner and the multi-stage flame hole type gas burner described above have a disadvantage in that they have a complicated structure and are difficult to manufacture, resulting in high costs.

スバーナにある。In order to solve the problem of tilting, the present invention has been developed to provide a stable system that does not cause backfire even when city gas with a high combustion rate is used, and does not cause lift without changing the flame load even when switching to natural gas. It was created with the purpose of providing a universal gas burner with a simple structure that can maintain combustion, and its gist is a slit-shaped central flame hole formed by a pair of partition plates, and stepped sections on both sides of the central flame hole. In a gas burner, a plurality of outer flame holes surrounded by a side plate having a plurality of outer flame holes are provided at a predetermined interval in the upper part of a mixing tube with a central flame hole oriented in the longitudinal direction,
A protrusion that curves outward is provided on the partition plate of the flame hole located outside the flame hole assembly located at the tip of the gas burner, and the above protrusion in the flame hole located on the mixing pipe inlet side is connected to the center part of the partition plate. The gas burner is characterized in that a notch is provided only in the central flame hole of adjacent flame hole portions, and further has a notch that connects the flame hole portions between the central flame holes of adjacent flame hole portions.
以下図面にもとづき本考案の実施例につき説明すると、
1はガスバーナの混合管3の上部にその長手方向に所定
の間隔を存して設けられた炎孔部である。Examples of the present invention will be described below based on the drawings.
Reference numeral 1 denotes flame holes provided at a predetermined interval in the longitudinal direction of the mixing tube 3 of the gas burner.
該炎孔部1の中央部には一対の仕切板2,2によって中
央炎孔1aが設けられている。A central flame hole 1a is provided in the center of the flame hole portion 1 by a pair of partition plates 2, 2.
6,6は中央炎孔1aの両側を囲った段押部を有する側
板でありこの段押部によって側面略W形の形状を有する
外側炎孔1b、lbが形成されている。Reference numerals 6 and 6 denote side plates having stepped portions surrounding both sides of the central flame hole 1a, and the stepped portions form outer flame holes 1b and lb each having a substantially W-shaped side surface.
さらに仕切板2,2の上方に外側に彎曲する突出部2a
、2aが設けられる。Furthermore, a protrusion 2a that curves outwardly above the partition plates 2, 2
, 2a are provided.
又ガスバーナの先端に位置する炎孔部5はその構成は炎
孔部1と同一であるが突出部は欠除している。Further, the flame hole portion 5 located at the tip of the gas burner has the same structure as the flame hole portion 1, but lacks the protruding portion.
さらに混合管の入口側に最も近く位置する炎孔部4は構
成は炎孔部1と同一であるが突出部2b、2bを仕切板
2,2上の中央部のみに設けている。Further, the flame hole section 4 located closest to the inlet side of the mixing tube has the same structure as the flame hole section 1, but has protrusions 2b, 2b provided only in the center part on the partition plates 2, 2.
9は隣接する炎孔部の中央炎孔間に形成され深さhでE
寸法だけ中央炎孔に入りこんだ炎孔部を連続する切欠部
である。9 is formed between the center flame holes of adjacent flame hole parts and is E at depth h.
This is a notch that continues the flame hole that extends into the center flame hole by the same dimension.
又7は炎孔部4に近接するパイロットバーナである。Further, 7 is a pilot burner located close to the flame hole portion 4.
本考案は上記の構成を有するので混合管3から混合ガス
が3分割された状態で噴出され中央火炎aと両側火炎す
、bとを形成するが、この場合中央炎孔1aから噴出す
る混合ガスは仕切板2,2の彎曲した突出部2a、2a
によって流速が低下し燃焼速度の遅いガスの場合にはリ
フトが防止される。Since the present invention has the above-mentioned configuration, the mixed gas is ejected from the mixing tube 3 in three parts, forming a central flame a and flames A and B on both sides.In this case, the mixed gas ejected from the central flame hole 1a. are the curved protrusions 2a, 2a of the partition plates 2, 2
This reduces the flow velocity and prevents lift in the case of gases with a slow combustion rate.
又外側炎孔1b、lbからの噴出混合ガスは先端で衝突
するとともに突出部2a、2aに当りやはり流速が低下
するのでリフトがおさえられる。Further, the mixed gas ejected from the outer flame holes 1b, 1b collides at the tips and hits the protrusions 2a, 2a, so that the flow velocity is also reduced, so that the lift is suppressed.
次に燃焼速度の速い混合ガスの場合には炎が短かくなり
このため仕切板2,2が過熱され炎孔郡全体の温度が上
昇して逆火を起す恐れがあるが、本考案においては仕切
板2,2間を流れる未燃焼ガスの冷却作用によって仕切
板2,2の過熱が防止されるので前記温度上昇による逆
火を完全に防止しうる。Next, in the case of a mixed gas with a high combustion speed, the flame becomes short and the partition plates 2 and 2 are overheated, raising the temperature of the entire flame hole group and causing a backfire. However, in the present invention, Since the partition plates 2, 2 are prevented from overheating due to the cooling effect of the unburned gas flowing between the partition plates 2, 2, backfire caused by the temperature rise can be completely prevented.
そしてこの未燃焼ガスによる冷却作用は混合管人口3a
から離れるほど燃焼による加熱によって小さくなるので
ガスバーナの最先端にある炎孔部5においては過熱され
易い突出部を欠除して逆火の発生を押えた。The cooling effect of this unburned gas is the mixing tube population 3a.
Since the farther away from the gas burner the smaller the flame becomes due to heating by combustion, the flame hole section 5 at the leading edge of the gas burner has no protruding section that is likely to be overheated to suppress the occurrence of backfire.
さらに混合管人口3aにもつとも近い炎孔部4はパイロ
ットバーナ7の火炎8を受けるので他の炎孔部よりも過
熱されしたがって上記冷却効果は大きくても逆火が発生
し易いが突出部2b、2bを仕切板2,2の中央部のみ
に設けたので炎口部の温度上昇が押えられて逆火は発生
しない。Furthermore, since the flame hole portion 4 closest to the mixing tube population 3a receives the flame 8 of the pilot burner 7, it is overheated more than the other flame hole portions, and therefore, even though the above-mentioned cooling effect is large, backfire is likely to occur, but the protrusion portion 2b, 2b is provided only at the center of the partition plates 2, 2, so that the temperature rise at the flame opening is suppressed and flashback does not occur.
この場合中央部のみではあるが突出部2b、2bがある
のでガスの噴出速度が低下し燃焼速度の遅いガスの場合
のリフトは防止される。In this case, since there are protrusions 2b, 2b, although only in the center, the gas ejection speed is reduced and lift is prevented in the case of gas with a slow combustion speed.
又切欠部9上にもガスが流れるので連続炎ができ火移り
性能も極めて良好である。Furthermore, since the gas flows over the notch 9, a continuous flame is generated and the flame transfer performance is extremely good.
本考案によるガスバーナは上記のように燃焼速度の異な
るガスを使用しても常に安定した燃焼状態を保持するこ
とができるとともに構造が簡単で製作が容易で経済的で
ありその効果は極めて大である。As mentioned above, the gas burner according to the present invention can always maintain a stable combustion state even when using gases with different combustion speeds, and is simple in structure, easy to manufacture, and economical, and its effects are extremely large. .
