本発明は、コンロ本体と、該コンロ本体の上面を覆う天板と、該天板に形成されたバーナ用開口を介して一部が露出するガスバーナとを備えるガスコンロに関する。 The present invention relates to a gas stove including a stove body, a top plate that covers an upper surface of the stove body, and a gas burner that is partially exposed through a burner opening formed in the top plate.
従来、ガスコンロにおいては、天板のバーナ用開口とガスバーナとの間からコンロ本体内部に吹きこぼれた煮汁や異物が侵入しないように、バーナ用開口とガスバーナとの間を閉塞する閉塞板を設けることが行われている（例えば、特許文献１参照）。 Conventionally, in a gas stove, a closing plate that closes between the burner opening and the gas burner is provided so that boiled juice and foreign matter spilled into the stove body from between the burner opening of the top plate and the gas burner do not enter. (For example, refer to Patent Document 1).
この種の閉塞板は、天板のバーナ用開口の周縁部にパッキンを介して載置され、取り外し自在に設けられている。 This type of closing plate is placed on the peripheral edge of the burner opening of the top plate via a packing and is detachably provided.
しかし、従来の閉塞板は、天板上に載置されている構成であるため、ガスバーナや天板に対して位置ずれも生じ易く、閉塞状態が不十分であるだけでなく、外観上も好ましくない。また、掃除等の手入れの際に容易に天板から容易に取り外すことができる反面、バーナ本体の掃除等の手入れの際にバーナ用開口が開放されるので、異物がコンロ本体内部に落下侵入するおそれがある。 However, since the conventional closing plate is configured to be mounted on the top plate, it is likely to be displaced with respect to the gas burner and the top plate, and not only the closed state is insufficient, but also the appearance is preferable. Absent. In addition, it can be easily removed from the top plate during cleaning such as cleaning, but the burner opening is opened during cleaning such as cleaning the burner body, so that foreign objects fall into the stove body. There is a fear.
上記の点に鑑み、本発明は、混合管の下流端部と天板のバーナ用開口との間を確実に閉塞することができ、良好な外観が得られて生産性も高いガスコンロを提供することを目的とする。 In view of the above points, the present invention provides a gas stove that can reliably block between the downstream end portion of the mixing tube and the burner opening of the top plate, has a good appearance, and has high productivity. For the purpose.
本発明は、コンロ本体と、該コンロ本体の上面を覆う天板と、該天板に形成されたバーナ用開口を介して一部が露出するガスバーナとを備えるガスコンロであって、
前記ガスバーナが、前記バーナ用開口に下流端部を臨ませた混合管と、前記天板上に露出するバーナ本体とを有し、バーナ本体の下面中央部に突設した筒状の混合気流入部を混合管の下流端に嵌合させて混合管からの混合気をバーナ本体に供給するように構成され、前記混合管の下流端部の外周壁とバーナ用開口の周縁との間に形成される環状の間隙を全周にわたり閉塞する閉塞板を、前記バーナ本体と同心となるように前記混合管に連結して設けたものにおいて、前記閉塞板は、その外周部下面がバーナ用開口の周縁に沿った天板上面にパッキンを介して当接され、前記パッキンは、前記閉塞板が非当接状態にあるとき、前記天板に対して移動自在に設けられていることを特徴とする。
The present invention is a gas stove comprising a stove body, a top plate that covers the top surface of the stove body, and a gas burner that is partially exposed through a burner opening formed in the top plate,
The gas burner has a mixing tube having a downstream end facing the burner opening, and a burner body exposed on the top plate, and has a cylindrical mixture inflow protruding from the center of the lower surface of the burner body the mixture from the mixing tube is fitted to the downstream end parts of the mixing tube is configured to supply to the burner body, between the peripheral edge of the outer peripheral wall and the burner opening of the downstream end portion of the front Stories mixing tube the closing plate for closing the annular gap formed over the entire circumference, in that provided coupled to said mixing tube so that the burner body and concentric, wherein the closure plate, the circumferential lower surface opening burner The packing is abutted on the top surface of the top plate along the periphery thereof, and the packing is provided so as to be movable with respect to the top plate when the closing plate is in a non-contact state. To do.
本発明によれば、閉塞板を混合管に連結したことにより、バーナ本体を混合管から取り外しても、閉塞板は混合管とバーナ用開口との間の閉塞状態を維持するので、バーナ本体の掃除等の手入れの際にバーナ用開口を介して異物がコンロ本体内部に落下侵入することを確実に防止することができる。 According to the present invention, by connecting the closing plate to the mixing tube, the closing plate maintains the closed state between the mixing tube and the burner opening even when the burner body is removed from the mixing tube. It is possible to reliably prevent foreign matter from falling into the stove body through the burner opening during cleaning such as cleaning.
また、閉塞板を混合管に連結したことにより、混合管に組み付けたバーナ本体と天板のバーナ用開口とに軸心ずれが生じても、閉塞板がバーナ用開口を確実に閉塞することができ、コンロ本体内部への異物や吹きこぼれた煮汁の侵入を防止することができる。しかも、閉塞板がバーナ用開口を閉塞していることによってコンロ本体とバーナ用開口との位置ずれは露出せず、外観の低下を防止することができる。更に、従来のように閉塞板を天板のバーナ用開口の内周縁に沿って固定するための手段が不要となり、部品点数も少なく、組み付け容易であるので生産性も高い。 In addition, by connecting the closing plate to the mixing tube, the closing plate can reliably block the burner opening even if the center of the burner body assembled to the mixing tube and the burner opening of the top plate are displaced. It is possible to prevent foreign matter and spilled broth from entering the stove body. In addition, since the closing plate closes the burner opening, the positional deviation between the stove body and the burner opening is not exposed, and the appearance can be prevented from deteriorating. Further, the conventional means for fixing the closing plate along the inner peripheral edge of the opening for the burner on the top plate becomes unnecessary, the number of parts is small, and assembly is easy, so that productivity is high.
また、本発明において、前記閉塞板は、その外周から混合管の下流端部に向って次第に高さが増加する形状に形成されていることが好ましい。これによれば、天板の上面に沿って流れる燃焼用の二次空気がバーナ本体に向うとき、閉塞板によって上昇方向に案内されるので、燃焼中のバーナ本体に二次空気を円滑に供給することができ、ガスバーナの良好な燃焼を得ることができる。また、吹きこぼれた煮汁が閉塞板上に溜まることがなく、閉塞板への汚れの付着による外観の低下が防止でき、汚れの拭き取り作業も容易であるため掃除等の手入れ性もよい。 Moreover, in this invention, it is preferable that the said obstruction | occlusion board is formed in the shape which height increases gradually toward the downstream end part of a mixing pipe | tube from the outer periphery. According to this, when the secondary air for combustion flowing along the upper surface of the top plate is directed to the burner main body in the upward direction by the closing plate, the secondary air is smoothly supplied to the burner main body during combustion. And good combustion of the gas burner can be obtained. In addition, since the spilled simmered juice does not accumulate on the blocking plate, the appearance can be prevented from being deteriorated due to the adhesion of dirt to the blocking plate, and the dirt can be easily wiped off.
また、本発明においては、前記天板から露出するバーナ本体の周囲に五徳が設けられ、該五徳は、その下部内側面が前記閉塞板の外周部に嵌合して位置決めされることが好ましい。五徳は、閉塞板により位置決めされた状態となっているので、バーナ本体の軸心と五徳の軸心を一致させることができ、バーナ本体に対する五徳の位置を良好な状態に維持することができる。 Further, in the present invention, it is preferable that virtues are provided around the burner body exposed from the top plate, and the virtues are positioned by fitting a lower inner surface thereof to an outer peripheral portion of the closing plate. Since the five virtues are positioned by the closing plate, the axis of the burner body can be aligned with the axis of the five virtues, and the position of the five virtues with respect to the burner body can be maintained in a good state.
更に、前記五徳は、前記閉塞板に載置されることが好ましい。これによれば、コンロ本体の歪みや天板の歪み等によりコンロ本体に支持されたガスバーナと天板との相対的な高さの変形に影響を受けることなく、バーナ本体に対する五徳の高さを一定に維持することができる。 Furthermore, it is preferable that the virtues are placed on the closing plate. According to this, without being affected by the deformation of the relative height of the gas burner supported on the stove body and the top plate due to distortion of the stove body or distortion of the top plate, the height of the five virtues with respect to the burner body is increased. Can be kept constant.
また、本発明の前記閉塞板は、その外周部下面がバーナ用開口の周縁に沿った天板上面にパッキンを介して当接され、前記パッキンは、前記閉塞板が非当接状態にあるとき、前記天板に対して移動自在に設けられている。 Further, the closing plate of the present invention is such that the lower surface of the outer peripheral portion is brought into contact with the top plate upper surface along the peripheral edge of the burner opening via a packing, and the packing is in a state where the closing plate is not in contact. , that provided movably relative to the top plate.
一般に、ガスバーナはコンロ本体に取り付け支持されるが、コンロ本体へのガスバーナの取り付け誤差により、天板のバーナ用開口に対してバーナ本体が軸心ずれを起こすことがある。このとき、バーナ用開口の内周縁にパッキンが嵌合して取り付けられている場合には、パッキンに対して閉塞板が位置ずれを起こす。このため、パッキンにより閉塞板とバーナ用開口との間を十分に封止できないだけでなく、閉塞板からパッキンの一部がはみ出して外観が低下するおそれがある。 Generally, the gas burner is attached to and supported by the stove body. However, due to an error in attaching the gas burner to the stove body, the burner body may be misaligned with respect to the burner opening of the top plate. At this time, when the packing is fitted and attached to the inner peripheral edge of the burner opening, the closing plate is displaced with respect to the packing. For this reason, not only cannot the seal between the closing plate and the burner opening be sufficiently sealed, but a part of the packing may protrude from the closing plate and the appearance may deteriorate.
そこで、本発明においては、閉塞板が非当接状態にあるときのパッキンを移動自在としたことにより、バーナ用開口とバーナ本体との軸心ずれが生じていても、そのずれ寸法に応じてパッキンが移動するので、軸心ずれの影響を受けることなく閉塞板とバーナ用開口との間を確実に密封することができ、外観の低下も防止することができる。 Therefore, in the present invention, by making the packing movable when the closing plate is in a non-contact state, even if an axial misalignment between the burner opening and the burner main body occurs, the packing size depends on the displacement dimension. Since the packing moves, the gap between the closing plate and the burner opening can be surely sealed without being affected by the axial misalignment, and the appearance can be prevented from being deteriorated.
以下、本発明の実施形態を図面を参照して説明する。本実施形態のガスコンロは、図１及び図２に要部を示すように、ガスバーナ１と、ガスバーナ１の周囲に設けられた五徳２とを備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The gas stove according to the present embodiment includes a gas burner 1 and five virtues 2 provided around the gas burner 1 as shown in FIG. 1 and FIG.
ガスバーナ１は、ガスコンロの一部を構成する天板３上に露出するバーナ本体４と、ガスコンロの他部を構成するコンロ本体５の内部で、底板６に台座部７を介して連結固定される混合管８とを備えている。混合管８の下流端部８ａは上向きに開口している。 The gas burner 1 is connected and fixed to a bottom plate 6 via a pedestal portion 7 inside a burner body 4 exposed on a top plate 3 constituting a part of the gas stove and a stove body 5 constituting the other part of the gas stove. And a mixing tube 8. The downstream end portion 8a of the mixing tube 8 opens upward.
図２に示すように、天板３は、コンロ本体５の上面を覆うように設けられ、バーナ本体４よりも大径のバーナ用開口９が形成された天板本体１０と、天板本体１０のバーナ用開口９を覆う閉塞板１１とで構成されている。天板本体１０は、金属板或いはガラス板により平坦に形成されており、閉塞板１１は、金属板により形成されている。 As shown in FIG. 2, the top plate 3 is provided so as to cover the upper surface of the stove body 5, and the top plate body 10 in which the burner opening 9 having a larger diameter than the burner body 4 is formed, and the top plate body 10. And a closing plate 11 that covers the burner opening 9. The top plate body 10 is formed flat by a metal plate or a glass plate, and the closing plate 11 is formed by a metal plate.
閉塞板１１には、中央部に混合管８の下流端部８ａが挿着される挿着孔１２が開設されている。また、閉塞板１１は、その外周から混合管８の下流端部８ａに向って段差を介して次第に高さが増加する形状に形成されている。 The closing plate 11 has an insertion hole 12 into which the downstream end 8a of the mixing tube 8 is inserted at the center. The blocking plate 11 is formed in a shape that gradually increases in height from the outer periphery toward the downstream end 8a of the mixing tube 8 through a step.
これによれば、調理の際に吹きこぼれた煮汁が溜まらずに外周に流すことができ、汚れが付着することによる外観の低下が防止でき、汚れの拭き取り作業も容易であるため掃除等の手入れ性もよい。 According to this, boiled juice that has been spilled during cooking can flow to the outer periphery without accumulating, can prevent deterioration of the appearance due to adhesion of dirt, and easy to wipe off dirt so that it can be easily cleaned, etc. Also good.
閉塞板１１は、天板３の一部を構成するものであるが、天板３には連結されていず、ガスバーナ１の混合管８にねじ部材１３により連結固定されている。閉塞板１１は、挿着孔１２に混合管８の下流端部８ａを挿着したとき、バーナ本体４と同心となる円形に形成されている。 The closing plate 11 constitutes a part of the top plate 3, but is not connected to the top plate 3, and is connected and fixed to the mixing tube 8 of the gas burner 1 by a screw member 13. The blocking plate 11 is formed in a circular shape that is concentric with the burner body 4 when the downstream end 8 a of the mixing tube 8 is inserted into the insertion hole 12.
閉塞板１１の外周部下面は、バーナ用開口９の周縁に沿った天板本体１０の上面にパッキン１４を介して当接されている。パッキン１４は、天板本体１０の上面に密着するシール部１４ａと、該シール部１４ａの外周に張り出して閉塞板１１の外周縁が当接する鍔部１４ｂと、シール部１４ａの内周から下方に延びる垂下部１４ｃとで構成されている。パッキン１４の垂下部１４ｃの外径は、バーナ用開口９の内径よりも少し小さく、閉塞板１１がシール部１４ａに非当接状態にあるとき（即ち、閉塞板１１の組み付け前の状態）には、前記天板本体１０に対して移動自在となっている。 The lower surface of the outer peripheral portion of the closing plate 11 is in contact with the upper surface of the top plate main body 10 along the periphery of the burner opening 9 via the packing 14. The packing 14 includes a seal portion 14a that is in close contact with the upper surface of the top plate body 10, a flange portion 14b that protrudes from the outer periphery of the seal portion 14a and contacts the outer peripheral edge of the closing plate 11, and a lower portion from the inner periphery of the seal portion 14a. The extending drooping part 14c is comprised. The outer diameter of the hanging portion 14c of the packing 14 is slightly smaller than the inner diameter of the burner opening 9, and when the closing plate 11 is not in contact with the seal portion 14a (that is, the state before the closing plate 11 is assembled). Is movable with respect to the top plate body 10.
これによれば、例えば、混合管８のコンロ本体５の底部６への取り付け位置の誤差により、混合管８に組み付けたバーナ本体４と天板３のバーナ用開口９との軸心ずれが生じても、バーナ用開口９の内周縁は、閉塞板１１の外周部により隠されるために、外観の低下が防止できる。また、前記パッキン１４は、その垂下部１４ｃの外径がバーナ用開口９の内径よりも少し小さく、天板本体１０に対して移動自在となっている。このため、混合管８に連結された閉塞板１１とバーナ用開口９とに軸心ずれが生じていても、そのずれ寸法に応じてパッキン１４が移動して、閉塞板１１の外周部下面とバーナ用開口９の周縁に沿った天板本体１０の上面との間を確実に密封することができる。 According to this, for example, due to an error in the attachment position of the mixing pipe 8 to the bottom portion 6 of the stove main body 5, an axial misalignment between the burner body 4 assembled to the mixing pipe 8 and the burner opening 9 of the top plate 3 occurs. However, since the inner peripheral edge of the burner opening 9 is concealed by the outer peripheral portion of the closing plate 11, the appearance can be prevented from being deteriorated. In addition, the outer diameter of the hanging portion 14 c of the packing 14 is slightly smaller than the inner diameter of the burner opening 9, and is movable with respect to the top plate body 10. For this reason, even if the axial center shift | offset | difference has arisen in the obstruction board 11 connected to the mixing pipe 8, and the opening 9 for burners, the packing 14 moves according to the deviation | shift dimension, and the outer peripheral part lower surface of the obstruction board 11 and The space between the top surface of the top plate body 10 along the periphery of the burner opening 9 can be reliably sealed.
五徳２は、環状の五徳枠２ａとこの五徳枠２ａの周方向に所定間隔を存してに固定支持された５つの五徳爪２ｂとからなる。五徳枠２ａは閉塞板１１の外周部に形成された段差に嵌合し、位置決めされた状態で閉塞板１１上に載置される。 The five virtues 2 are composed of an annular five virtue frame 2a and five five virtue claws 2b fixedly supported at predetermined intervals in the circumferential direction of the five virtue frame 2a. The five-virtual frame 2a is fitted on a step formed on the outer peripheral portion of the closing plate 11 and placed on the closing plate 11 in a positioned state.
即ち、五徳２は、閉塞板１１を介して混合管８に載置された状態となっている。これによれば、混合管８に組み付けられたバーナ本体４の軸心と五徳２の軸心を一致させることができる。更に、コンロ本体５に歪み等が発生して天板本体１０と底部６との距離が変化しても、五徳２は、混合管８に連結された閉塞板１１に載置されていることにより、バーナ本体４と五徳２上に載置した鍋底との間隔距離を一定に維持することができる。 That is, the virtues 2 are in a state of being placed on the mixing tube 8 via the closing plate 11. According to this, the axial center of the burner main body 4 assembled | attached to the mixing pipe 8 and the axial center of Gotoku 2 can be made to correspond. Furthermore, even if distortion or the like occurs in the stove body 5 and the distance between the top plate body 10 and the bottom 6 changes, the virtues 2 are placed on the closing plate 11 connected to the mixing tube 8. The distance between the burner body 4 and the bottom of the pan placed on the Gotoku 2 can be kept constant.
なお、図示しないが、五徳が天板本体１０上に載置される形状のものであっても、環状の五徳枠の内周面を閉塞板１１の外周部に嵌合させることにより、バーナ本体の軸心と五徳の軸心を一致させることができる。また、例えば、各五徳爪の下端縁が載置面となる五徳の場合には、各五徳爪の下部内側面を閉塞板１１の外周部に嵌合するようにしてもよい。 Although not shown, even if the virtues are shaped to be placed on the top plate main body 10, the burner main body can be obtained by fitting the inner peripheral surface of the annular virtuosity frame to the outer peripheral portion of the closing plate 11. Can be aligned with the axis of five virtues. Further, for example, in the case of five virtues in which the lower end edge of each virtuosity claw is a mounting surface, the lower inner surface of each virtuosity claw may be fitted to the outer peripheral portion of the closing plate 11.
バーナ本体４は、親バーナ部１５と子バーナ部１６とを備えて所謂親子バーナを構成している。混合管８は、図３に示すように、親バーナ部１５に混合ガスを供給する親バーナ用混合管部１７と、子バーナ部１６に混合ガスを供給する子バーナ用混合管部１８とを備えている。 The burner body 4 includes a parent burner portion 15 and a child burner portion 16 to constitute a so-called parent-child burner. As shown in FIG. 3, the mixing tube 8 includes a parent burner mixing tube portion 17 that supplies a mixed gas to the parent burner portion 15, and a child burner mixing tube portion 18 that supplies a mixed gas to the child burner portion 16. I have.
図２に示すように、混合管８の下流端部８ａは、親バーナ用混合管部１７の内側に子バーナ用混合管部１８が収容されて二重管構造とされる。 As shown in FIG. 2, the downstream end portion 8 a of the mixing tube 8 has a double tube structure in which the mixing tube portion 18 for child burners is accommodated inside the mixing tube portion 17 for parent burners.
図１及び図２に示すように、バーナ本体４は、バーナボディ１９と、一対のバーナヘッド（親バーナヘッド２０及び子バーナヘッド２１）とにより構成されている。バーナボディ１９には、その外側に親バーナ部１５の分布室２２が形成されており、内側に子バーナ部１６の分布室２３が形成されている。親バーナ部１５の分布室２２上に親バーナヘッド２０が載置されることにより、親バーナ部１５の外周に複数の親バーナ炎孔２４が形成され、子バーナ部１６の分布室２３上に子バーナヘッド２１が載置されることにより、子バーナ部１６の外周に複数の子バーナ炎孔２５が形成される。 As shown in FIGS. 1 and 2, the burner body 4 is composed of a burner body 19 and a pair of burner heads (a master burner head 20 and a child burner head 21). In the burner body 19, a distribution chamber 22 of the parent burner portion 15 is formed on the outer side, and a distribution chamber 23 of the child burner portion 16 is formed on the inner side. By placing the parent burner head 20 on the distribution chamber 22 of the parent burner portion 15, a plurality of parent burner flame holes 24 are formed on the outer periphery of the parent burner portion 15, and on the distribution chamber 23 of the child burner portion 16. By placing the child burner head 21, a plurality of child burner flame holes 25 are formed on the outer periphery of the child burner portion 16.
また、バーナボディ１９の下面中央部には、混合管８の下流端部８ａに対応して筒状の混合気流入部２６が設けられている。図２に示すように、混合気流入部２６は、外側に位置する親バーナ用通路２７と、その内側の子バーナ用通路２８とで構成されている。混合気流入部２６が混合管８の下流端部８ａに嵌合すると、親バーナ用通路２７が親バーナ用混合管部１７に連通すると同時に、子バーナ用通路２８が子バーナ用混合管部１８に連通する。なお、混合気流入部２６は、混合管８の下流端部８ａに着脱自在に嵌合し、掃除等の手入れの際にはバーナ本体４を混合管８から容易に取り外せるようになっている。 In addition, a cylindrical air-fuel mixture inflow portion 26 is provided at the center of the lower surface of the burner body 19 so as to correspond to the downstream end portion 8 a of the mixing pipe 8. As shown in FIG. 2, the air-fuel mixture inflow portion 26 includes a parent burner passage 27 located on the outer side and a child burner passage 28 on the inner side. When the air-fuel mixture inflow portion 26 is fitted to the downstream end portion 8a of the mixing tube 8, the parent burner passage 27 communicates with the parent burner mixing tube portion 17, and at the same time, the child burner passage 28 is connected to the child burner mixing tube portion 18. Communicate with. The air-fuel mixture inflow portion 26 is detachably fitted to the downstream end portion 8a of the mixing pipe 8 so that the burner body 4 can be easily detached from the mixing pipe 8 when cleaning or the like is maintained.
また、混合気流入部２６は、図２に示すように、バーナボディ１９の子バーナ部１６の下部位置に配置されているため、親バーナ用通路２７は、図１及び図２に示すように、子バーナ部１６の側から放射状に延びる連絡管部２９により親バーナ部１５の分布室２２に連通するようになっている。 Further, as shown in FIG. 2, the air-fuel mixture inflow portion 26 is disposed at a lower position of the child burner portion 16 of the burner body 19, so that the parent burner passage 27 is formed as shown in FIGS. 1 and 2. The communication tube portion 29 extending radially from the child burner portion 16 communicates with the distribution chamber 22 of the parent burner portion 15.
また、前記混合管８の親バーナ用混合管部１７と子バーナ用混合管部１８との夫々の上流端には、図示しないガスノズルが臨む。ガスノズルから燃料ガスが噴出されると、燃料ガスの噴出に伴い一次空気が吸引され、混合ガスが生成される。 A gas nozzle (not shown) faces the upstream ends of the mixing tube portion 17 for the parent burner and the mixing tube portion 18 for the child burner of the mixing tube 8. When the fuel gas is ejected from the gas nozzle, the primary air is sucked with the ejection of the fuel gas, and a mixed gas is generated.
図２に示すように、親バーナヘッド２０の一部には、点火ターゲット３０が形成されている。点火ターゲット３０は、支持部材３１を介して混合管８に支持された点火プラグ３２の先端に対向し、点火プラグ３２の放電を受けて親バーナ部１５に点火する。点火プラグ３２は、閉塞板１１を貫通して上方に延びている。なお、図１において符号３３で示すものは子バーナ部１６の着火を検知する熱電対である。図示しないが、熱電対３３も、点火プラグ３２と同様に混合管８に支持されており、閉塞板１１を貫通して上方に延びている。 As shown in FIG. 2, an ignition target 30 is formed on a part of the parent burner head 20. The ignition target 30 faces the tip of the spark plug 32 supported by the mixing tube 8 via the support member 31, receives the discharge of the spark plug 32, and ignites the parent burner unit 15. The spark plug 32 extends upward through the closing plate 11. In addition, what is shown with the code | symbol 33 in FIG. 1 is the thermocouple which detects the ignition of the child burner part 16. FIG. Although not shown, the thermocouple 33 is also supported by the mixing tube 8 like the spark plug 32 and extends upward through the blocking plate 11.
親バーナ部１５で形成される火炎は、図１及び図３に示すように、親バーナヘッド２０に形成された火移り用のスリット２０ａを介して子バーナ部１６に火移りし、これによって子バーナ部１６が点火される。子バーナ部１６で形成される火炎には前記連絡管部２９の間の空隙から二次空気が供給される。このとき、閉塞板１１は、その外周から混合管８の下流端部８ａに向って段差を介して次第に高さが増加する形状に形成されていることにより、天板の上面からバーナ本体４に向って上昇する二次空気流を形成する。このため、親バーナ部１５だけでなく子バーナ部１６にも十分な量の二次空気を供給することができ、良好な燃焼状態を得ることができる。 As shown in FIGS. 1 and 3, the flame formed in the parent burner portion 15 is transferred to the child burner portion 16 via the slit 20a for transferring fire formed in the parent burner head 20, thereby The burner part 16 is ignited. Secondary air is supplied to the flame formed by the sub burner portion 16 from the gap between the connecting pipe portions 29. At this time, the closing plate 11 is formed in a shape in which the height gradually increases from the outer periphery toward the downstream end portion 8a of the mixing tube 8 through a step, so that the burner body 4 extends from the top surface of the top plate. Creates a secondary air stream that rises towards it. Therefore, a sufficient amount of secondary air can be supplied not only to the parent burner part 15 but also to the child burner part 16, and a good combustion state can be obtained.
なお、本実施形態においては、ガスバーナ１が親バーナ部１５と子バーナ部１６とを備えるものを示したが、図示しないが、バーナ本体の中央部に混合管が嵌合する構成のガスバーナであれば、単一のバーナ部を備えるガスバーナであっても本発明を好適に採用することができる。 In this embodiment, the gas burner 1 includes the parent burner portion 15 and the child burner portion 16. However, although not shown, the gas burner may be configured so that the mixing tube is fitted to the center portion of the burner body. For example, even if it is a gas burner provided with a single burner part, this invention can be employ | adopted suitably.
