Description

【0001】
【発明の属する技術分野】
本発明はガスバーナに関し、より詳しくはガスこんろに用いるガスバーナに関する。
【0002】
【従来の技術】
ガスこんろ用ガスバーナとしては、環状体の上面部又は上端外周部に多数の円形状炎口、又はスリット状炎口を形成したものが広く使用されている。環状体にはガス供給管に接続される接続部が設けられていて、環状体の内部に形成された環状の混合室にこの接続部から燃料ガスが供給され、この混合室内で燃料ガスは一次空気あるいは酸素と均一に混合されて燃焼可能な予混合燃料ガスとなる。形成された予混合燃料ガスは炎口から噴出されて2次空気の存在下で燃焼し、加熱用の火炎を形成する。
【0003】
【発明が解決しようとする課題】
ところで、ガスバーナの炎口は、ガス供給管からの供給量が小さくなっても混合室内の予混合燃料ガスの噴出速度があまり小さくならないように、十分小さくあるいは狭く形成される。したがって、ガスバーナの炎口は目詰まりしやすく、飲食店などで業務用に用いる場合には頻繁に、例えば業務終了時あるいは業務開始時のいずれかの時点で、炎口を清掃する必要がある。ところが、鍋等の被加熱体からの煮こぼれなどが炎口内に流れ込んで固まっていると簡単には清掃できない場合も多く、炎口内が汚れたままのガスバーナがそのまま使用されているケースも見受けられる。
【0004】
そこで、本発明は頻繁に清掃する必要がなく、また必要なときには容易に清掃することができ、その結果、常に適切な火炎を形成しておくことのできるガスバーナの提供を目的とする。
【0005】
【課題を解決するための手段】
この目的を達成するため、本発明のガスバーナは、炎口から噴出する混合燃料ガスを燃焼させて火炎を形成するガスバーナであって、燃料ガスと空気とを均一に混合するための混合室が内部に形成され、この混合室に連なるガス供給口が上側に設けられた環状のバーナ本体と、このバーナ本体に着脱可能に取り付けられた環状のカバー部材と、このカバー部材の内側に配置されている噴出口構成部と、を備え、前記カバー部材は前記バーナ本体の前記ガス供給口を覆う覆い部を有していて、前記カバー部材の前記覆い部の内端縁と前記噴出口構成部の上端との間には前記ガス供給口から供給された前記混合燃料ガスを外側に向かって噴出する(均一に噴出する)ための狭い又は細いガス噴出口が形成されているものである。カバー部材の覆い部(環状の覆い部)によってバーナ本体の上側が覆われて煮こぼれなどがバーナ本体のガス供給口に流れ込むことが防止される。覆い部の内端は少なくともガス供給口の内端位置まで延びていることが好ましく、より好ましくは覆い部をガス供給口を越える位置まで延ばしておく。バーナ本体にカバー部材を取り付けることのみによってガスバーナを構成すると、火炎はバーナ本体のガス供給口のすぐ外側から形成されるので、カバー部材が直接熱せられ、熱負荷によりカバー部材の寿命が極めて短くなるし、また被加熱体に伝達される熱量が減少するので加熱効率が悪くなる。本発明では噴出口構成部を形成しているので火炎はガス噴出口のすぐ外側に形成される。しかも、カバー部材をバーナ本体から取り外ずして清掃を行うことができるので、狭い又は細いガス噴出口の清掃に手間取ることがない。そして、ガス噴出口が汚れにくくなるように構成することも極めて容易である。
【0006】
本発明はより具体的には、バーナ本体の外周部に着脱可能に嵌め付けられた薄肉の金属製環状あるいは筒状外側カバー部材と、この環状外側カバー部材の内側に配置されている内側筒状部とを備え、環状外側カバー部材はバーナ本体のガス供給口を覆う覆い部を有していて、ガス供給口はこの内側筒状部と環状外側カバー部材との間に位置するように構成される。ガス噴出口は通常、全周に亘って、すなわちスリット状に又はほぼ全周に亘って形成される。バーナ本体は通常、鋳造によって厚肉に形成される。
【0007】
カバー部材の覆い部がガス供給口を越える位置まで延びていれば、ガス供給口を煮こぼれから保護できるだけでなく、ガス供給口を炎口とした場合よりも火炎を内側に集めることができる。したがって、被加熱体の外側に火炎が逃げてしまうことを効果的に防止できるので、加熱効率を高めることができる。さらに加熱効率を高めるためには、混合燃料ガスがガス噴出口から内側に向かって上方へ噴出されるように構成すべきである。したがって、覆い部を内側に向かって上方へ傾斜するように形成し、ガス供給口から供給された混合燃料ガスが覆い部に沿って流れ、ガス噴出口から内側上方に噴出されるように構成するのが効果的である。より好ましくは覆い部の内端を内側筒状部の上端よりも多少内側に位置するまで延ばしておく。さらに、混合室からガス供給口に至るガス供給路を内側に向かって上方に傾斜させておくことは効果的である。ここで、カバー部材の覆い部と噴出口構成部あるいは内側筒状部との間に比較的広い環状のガス溜めスペースを形成しておくことは、燃焼効率を高めるために得策である。ガス供給口から供給された混合燃料ガスはガス溜めスペース内でより均一に混合されて燃焼しやすい状態となる。すなわち、バーナ本体のガス供給口形成部、カバー部材及び噴出口構成部あるいは内側筒状部との間にマニホールドよりも十分容積が小さいガス溜めスペースを構成する。
【0008】
バーナー本体のガス供給口やガス噴出口構成部をより簡単に清掃できるようにするためには、内側筒状部もバーナ本体から取り外すことができるようにしておくべきである。すなわち、外側のカバー部材、内側筒状部及びバーナー本体をそれぞれ別体として形成し、これらを分解可能に組み立てることによりにガスバーナを構成する。内側筒状部は通常、薄肉の金属製筒状体として形成される。カバー部材及び内側筒状部のバーナ本体への取り付けは単なる嵌め付けにより行うのが好ましい。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【0010】
図1は本発明に係るガスバーナの分解斜視図、図2はガスバーナの断面図である。
【0011】
バーナ本体1は環状のドーナツ体に形成され、外周面に一体的に接続形成された接続部3を有している。接続部3の外端部分内周には雌ネジ部分5が形成されていて、この雌ネジ部分5に先端部外周に形成された雄ネジ部7をねじ込むことにより、接続部3にガス供給管9が接続される。ドーナツ状のバーナ本体1は接続部3のガス流路11に連通する環状の混合室13が形成されるように中空に構成されていて、ガス供給管9から接続部3に一次空気を引き込んで(矢印X参照)供給された都市ガス、プロパンガスあるいは天然ガス(燃料ガス:矢印Y参照)はガス流路11を通過して混合室13内に流れ込み、この混合室13内で一次空気と均一に混合されて燃焼可能な予混合ガスとなる(図2の矢印Z参照)。
【0012】
バーナ本体1の上側外周部は若干小径に、すなわち外径が多少小さく形成されて外側嵌め込み部15を構成し、上面17は幅方向やや内側よりを頂とする屋根状の断面形状を有している。上面17の外側傾斜面19は内側に向かって上方に大きな角度で、すなわち急に傾斜するカバー支持面を構成し、内側傾斜面21は内側に向かって下方に小さな角度で、すなわち緩く傾斜するガス供給面を構成していて、このガス供給面を構成する内側傾斜面21には、混合室13に連なるガス供給路23が全周にわたって周方向等間隔で多数個開口している。ガス供給路23は混合室13からガス供給面21までこのガス供給面21と直交する方向に延びている。また、バーナ本体1の上側内周部は若干大径に、すなわち内径が多少大きく形成されて内側嵌め込み部25を構成している(図3も参照:図3はバーナ本体1の上側部分の拡大図)。
【0013】
バーナ本体1の内側嵌め込み部25には、外径がこの内側嵌め込み部25の内径とほぼ同一に形成された薄肉の短い内側筒状体27(噴出口構成部又は内側筒状部)が嵌め込まれていて、この内側筒状体27の下端は内側嵌め込み部25の環状の段部面29上に載って支持され、内側筒状体27の上端はバーナ本体1の上面17の頂より若干高く位置している。バーナ本体1の外側嵌め込み部15には、薄肉のカバー部材31の下側筒状部33が嵌め付けられていて、このカバー部材31の下側筒状部33よりも上側の傾斜部35(覆い部:より詳しくは傾斜部35の内側部分が覆い部に該当する)は截頭円錐状に縮径し、上端縁37、すなわち開口縁はガス供給路23のガス供給口39形成位置を越えてバーナ本体1の内周面よりやや内側まで延びている。カバー部材31の傾斜部35の傾きはカバー支持面である外側傾斜面19の傾きと同一に形成されていて、カバー部材31は外側傾斜面19上に気密的に載置された状態で支持されている。なお、図3中41は外側嵌め込み部15の環状の段部面である。
【0014】
内側筒状体27の上端はカバー部材31の上端部あるいは内端部との間に狭い環状のガス噴出口43が構成される高さまで延びている。したがって、ガス供給口39からカバー部材31と内側筒状体27との間に供給された混合プロパンガスは、このカバー部材31と内側筒状体27との間に形成されている比較的広いガス溜めスペース45内でより均一に混合されてガス噴出口43から適当な流速で噴出し、カバー部材31の上端開口47位置に符号49で示すような環状の火炎を形成する。したがって、このガスバーナではガス噴出口43を炎口と捉えることができる。ここでは、カバー部材31の傾斜部35内端を内側筒状体27の上端よりも内側に位置させているので、混合プロパンガスを確実に内側に向かって上方に噴出させることができるし、また、ガス噴出口43が傾斜部35内端によって覆われることとなるので汚れにくい。
【0015】
ガス噴出口43は狭いために目詰まりする場合があるが、カバー部材31及び内側筒状体27を取り外してそれぞれを清掃することにより、ガス噴出口43の汚れ又は目詰まりを簡単に取り除くことができる。また、カバー部材31に覆われてバーナ本体1のガス供給口39には煮こぼれなどによる直接の強固な汚れが付着しないので頻繁に清掃する必要はなく、また必要な場合には簡単に清掃することができる。
【0016】
【発明の効果】
以上説明したように、本発明のガスバーナは、カバー部材をバーナ本体から取り外して簡単かつ迅速に清掃できるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a gas burner, and more particularly to a gas burner used for a gas stove.
[0002]
[Prior art]
As a gas burner for gas stoves, a gas burner in which a large number of circular flame openings or slit-like flame openings are formed on the upper surface portion or upper end outer peripheral portion of an annular body is widely used. The annular body is provided with a connection portion connected to the gas supply pipe, and fuel gas is supplied from the connection portion to the annular mixing chamber formed inside the annular body, and the fuel gas is primarily supplied in the mixing chamber. A premixed fuel gas that can be combusted by being uniformly mixed with air or oxygen. The formed premixed fuel gas is ejected from the flame opening and burned in the presence of secondary air to form a heating flame.
[0003]
[Problems to be solved by the invention]
By the way, the flame outlet of the gas burner is formed sufficiently small or narrow so that the injection speed of the premixed fuel gas in the mixing chamber does not become so small even if the supply amount from the gas supply pipe becomes small. Therefore, the flame burner of the gas burner is easily clogged, and when used for business purposes in restaurants and the like, it is necessary to clean the flame burner frequently, for example, at the end of the business or at the start of the business. However, there are many cases where it is not easy to clean if boiled spills from heated objects such as pans flow into the flame mouth and solidify, and there are cases where gas burners with the flame mouth dirty are used as they are .
[0004]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gas burner which does not need to be frequently cleaned and can be easily cleaned when necessary, and as a result, an appropriate flame can always be formed.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the gas burner of the present invention is a gas burner that forms a flame by burning a mixed fuel gas ejected from a flame opening, and has a mixing chamber for uniformly mixing the fuel gas and air. An annular burner body provided with a gas supply port connected to the mixing chamber on the upper side, an annular cover member detachably attached to the burner body, and an inner side of the cover member. The cover member has a cover portion that covers the gas supply port of the burner body, and an inner edge of the cover portion of the cover member and an upper end of the jet port configuration portion A narrow or narrow gas outlet for ejecting the mixed fuel gas supplied from the gas supply port toward the outside (uniformly ejected) is formed between the two. The upper part of the burner body is covered by the cover part (annular cover part) of the cover member, so that spills and the like are prevented from flowing into the gas supply port of the burner body. The inner end of the cover part preferably extends at least to the position of the inner end of the gas supply port, and more preferably the cover part extends to a position beyond the gas supply port. If the gas burner is configured only by attaching the cover member to the burner body, the flame is formed from just outside the gas supply port of the burner body, so the cover member is heated directly, and the life of the cover member becomes extremely short due to the thermal load. In addition, since the amount of heat transferred to the object to be heated is reduced, the heating efficiency is deteriorated. In the present invention, since the jet nozzle component is formed, the flame is formed just outside the gas jet nozzle. In addition, since the cleaning can be performed without removing the cover member from the burner body, it does not take time to clean the narrow or narrow gas outlet. And it is also very easy to comprise so that a gas jet nozzle may become difficult to get dirty.
[0006]
More specifically, the present invention is a thin metal annular or tubular outer cover member that is detachably fitted to the outer peripheral portion of the burner body, and an inner tubular member disposed inside the annular outer cover member. The annular outer cover member has a cover portion that covers the gas supply port of the burner body, and the gas supply port is configured to be positioned between the inner cylindrical portion and the annular outer cover member. The The gas outlet is usually formed over the entire circumference, that is, in a slit shape or substantially over the entire circumference. The burner body is usually formed thick by casting.
[0007]
If the cover part of the cover member extends to a position beyond the gas supply port, not only can the gas supply port be protected from being spilled, but also the flame can be collected on the inside as compared with the case where the gas supply port is used as a flame port. Therefore, it is possible to effectively prevent the flame from escaping to the outside of the heated object, so that the heating efficiency can be increased. In order to further increase the heating efficiency, the mixed fuel gas should be configured to be ejected upward from the gas ejection port toward the inside. Therefore, the cover part is formed so as to incline upward toward the inside, and the mixed fuel gas supplied from the gas supply port flows along the cover part and is jetted upward from the gas outlet. Is effective. More preferably, the inner end of the cover part is extended until it is located slightly inside the upper end of the inner cylindrical part. Furthermore, it is effective to incline the gas supply path from the mixing chamber to the gas supply port upward inward. Here, forming a relatively wide annular gas reservoir space between the cover portion of the cover member and the jet outlet constituting portion or the inner cylindrical portion is a good measure for improving the combustion efficiency. The mixed fuel gas supplied from the gas supply port is more uniformly mixed in the gas reservoir space and is in a state where it is easy to burn. That is, a gas reservoir space having a volume sufficiently smaller than that of the manifold is formed between the gas supply port forming portion, the cover member and the jet outlet constituting portion or the inner cylindrical portion of the burner body.
[0008]
In order to make it easier to clean the gas supply port and gas jet outlet component of the burner body, the inner cylindrical part should also be removable from the burner body. That is, the outer cover member, the inner cylindrical portion, and the burner main body are formed as separate bodies, and the gas burner is configured by assembling them so that they can be disassembled. The inner cylindrical portion is usually formed as a thin metal cylindrical body. The cover member and the inner cylindrical part are preferably attached to the burner body by simple fitting.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is an exploded perspective view of a gas burner according to the present invention, and FIG. 2 is a sectional view of the gas burner.
[0011]
The burner main body 1 is formed in an annular donut body and has a connection portion 3 that is integrally connected to the outer peripheral surface. A female screw portion 5 is formed on the inner periphery of the outer end portion of the connection portion 3, and a gas supply pipe is connected to the connection portion 3 by screwing a male screw portion 7 formed on the outer periphery of the distal end portion into the female screw portion 5. 9 is connected. The donut-shaped burner body 1 is hollow so that an annular mixing chamber 13 communicating with the gas flow path 11 of the connection portion 3 is formed, and primary air is drawn into the connection portion 3 from the gas supply pipe 9. (See arrow X) The supplied city gas, propane gas or natural gas (fuel gas: see arrow Y) flows into the mixing chamber 13 through the gas flow path 11 and is uniform with the primary air in the mixing chamber 13. To a combustible premixed gas (see arrow Z in FIG. 2).
[0012]
The upper outer peripheral portion of the burner body 1 has a slightly smaller diameter, that is, the outer diameter is slightly smaller to form the outer fitting portion 15, and the upper surface 17 has a roof-like cross-sectional shape with the width direction slightly above the inner side. Yes. The outer inclined surface 19 of the upper surface 17 constitutes a cover support surface that is inclined upward at a large angle, that is, a sudden inclination, and the inner inclined surface 21 is a gas that is inclined gently at a small angle downward, that is, a gently inclined gas. A plurality of gas supply passages 23 connected to the mixing chamber 13 are opened at equal intervals in the circumferential direction on the inner inclined surface 21 constituting the gas supply surface. The gas supply path 23 extends from the mixing chamber 13 to the gas supply surface 21 in a direction orthogonal to the gas supply surface 21. Further, the upper inner peripheral portion of the burner body 1 is formed to have a slightly larger diameter, that is, the inner diameter is slightly larger to constitute the inner fitting portion 25 (see also FIG. 3: FIG. 3 is an enlarged view of the upper portion of the burner body 1. Figure).
[0013]
The inner fitting portion 25 of the burner main body 1 is fitted with a thin short inner cylindrical body 27 (a jet outlet constituting portion or an inner cylindrical portion) whose outer diameter is substantially the same as the inner diameter of the inner fitting portion 25. The lower end of the inner cylindrical body 27 is supported on and supported on the annular step surface 29 of the inner fitting portion 25, and the upper end of the inner cylindrical body 27 is positioned slightly higher than the top of the upper surface 17 of the burner body 1. is doing. A lower tubular portion 33 of a thin cover member 31 is fitted to the outer fitting portion 15 of the burner body 1, and an inclined portion 35 (cover) is provided above the lower tubular portion 33 of the cover member 31. Portion: more specifically, the inner portion of the inclined portion 35 corresponds to the cover portion), and the upper end edge 37, that is, the opening edge extends beyond the position where the gas supply port 39 is formed in the gas supply path 23. The burner body 1 extends slightly inward from the inner peripheral surface. The inclination of the inclined portion 35 of the cover member 31 is formed to be the same as the inclination of the outer inclined surface 19 that is the cover support surface, and the cover member 31 is supported in an airtight state on the outer inclined surface 19. ing. In FIG. 3, reference numeral 41 denotes an annular step surface of the outer fitting portion 15.
[0014]
The upper end of the inner cylindrical body 27 extends to a height at which a narrow annular gas outlet 43 is formed between the upper end portion or the inner end portion of the cover member 31. Therefore, the mixed propane gas supplied from the gas supply port 39 between the cover member 31 and the inner cylindrical body 27 is a relatively wide gas formed between the cover member 31 and the inner cylindrical body 27. More uniformly mixed in the reservoir space 45 and ejected from the gas ejection port 43 at an appropriate flow rate, and an annular flame as indicated by reference numeral 49 is formed at the upper end opening 47 position of the cover member 31. Therefore, in this gas burner, the gas outlet 43 can be regarded as a flame outlet. Here, since the inner end of the inclined portion 35 of the cover member 31 is positioned on the inner side of the upper end of the inner cylindrical body 27, the mixed propane gas can be reliably jetted upward toward the inner side, and The gas outlet 43 is covered with the inner end of the inclined portion 35, so that it is difficult to get dirty.
[0015]
The gas outlet 43 may be clogged because it is narrow, but by removing the cover member 31 and the inner cylindrical body 27 and cleaning each of them, dirt or clogging of the gas outlet 43 can be easily removed. it can. Further, since the gas supply port 39 of the burner body 1 covered with the cover member 31 is not directly adhered to the gas supply port 39 due to spilling or the like, it is not necessary to clean frequently, and if necessary, it is easily cleaned. be able to.
[0016]
