また、壁部１１には、下端から上下方向の中間位置まで側面を開放させる一対の切欠部１３，１３が、点対称に形成されており、その切欠部１３，１３の開口縁を含む壁部１１の下端全周には、フランジが形成されている。このうち切欠部１３，１３を除く最下端に位置する点対称部分は、器体側への取付フランジ１４，１４となり、取付フランジ１４，１４より上段となる切欠部１３，１３の上縁部分は、器体への取付状態で天板の裏面に当接する位置決めフランジ１５，１５となっている。なお、各取付フランジ１４には、等間隔で取付孔１６，１６・・が穿設されている。 Furthermore, a ring-shaped upper flange 10 is provided around the upper end of the outer cylinder 4, and the outer periphery of the upper flange 10 is located concentrically with the outer cylinder 4, and the lower end is below the lower end of the outer cylinder 4. And the cylindrical wall part 11 located above the lower end of the inner cylinder 5 is provided in the circumference. An ignition electrode and a thermocouple provided in a container such as a built-in stove are accommodated between the outer cylinder 4 and the wall portion 11, and the accommodated ignition electrode and thermocouple are accommodated in the upper flange 10. The through holes 12 and 12 are formed so as to protrude upward.
In addition, the wall portion 11 is formed with a pair of notches 13 and 13 that are open symmetrically from the lower end to the middle position in the vertical direction, and is formed symmetrically with the wall portion including the opening edge of the notches 13 and 13. A flange is formed on the entire circumference of the lower end of 11. Of these, the point-symmetrical portion located at the lowermost end excluding the notches 13 and 13 is the mounting flanges 14 and 14 on the body side, and the upper edge portions of the notches 13 and 13 that are higher than the mounting flanges 14 and 14 are The positioning flanges 15 and 15 are in contact with the back surface of the top plate when attached to the container. Each mounting flange 14 is provided with mounting holes 16, 16,.

１７，１７・・は、外筒４と壁部１１との間に設けられて両者を連結する平面視放射状の外リブで、外筒４の外面から取付フランジ１４，１４が形成される壁部１１部分に対して一対ずつ点対称に配置されている。各外リブ１７の下端は、最も高い外筒４の下端との連結部分と、最も低い壁部１１の下端との連結部分とが夫々水平面１７ａ，１７ｂとなり、両水平面１７ａ，１７ｂ間を傾斜面１７ｃで繋ぐ段差状となっている。
また、外筒４の下面で内周側には、下方へ突出するリング状の段部１８が周設されると共に、内周面には、段部１８と連続して段部１８よりも下方へ突出する３つの突起１９，１９・・が、周方向へ等間隔で形成されている。 Reference numerals 17, 17... Are radial ribs provided between the outer cylinder 4 and the wall portion 11 to connect the two, and are wall portions in which mounting flanges 14, 14 are formed from the outer surface of the outer cylinder 4. A pair of points is arranged symmetrically with respect to the 11 portions. At the lower end of each outer rib 17, the connecting portion with the lower end of the highest outer cylinder 4 and the connecting portion with the lower end of the lowest wall portion 11 become horizontal planes 17a and 17b, respectively, and an inclined surface is formed between both horizontal planes 17a and 17b. It has a stepped shape connected by 17c.
In addition, a ring-shaped step portion 18 projecting downward is provided on the inner peripheral side of the lower surface of the outer cylinder 4, and the inner peripheral surface is continuous with the step portion 18 and below the step portion 18. Three projections 19, 19,... Projecting in the circumferential direction are formed at equal intervals in the circumferential direction.

一方、混合管３は、ステンレス製の上板２０と下板２１とをプレス成形して外周縁同士をかしめ接合することで、図４にも示すように、燃料ガスと燃焼用空気とが供給されるすり鉢状のスロート部２２と、そのスロート部２２と同軸上に連設される混合部２３と、その混合部２３の端部に連設されてバーナ本体２と連結される先端部２４とを一体形成してなる。先端部２４を形成する上板２０には、バーナ本体２の外筒４がリング状のゴムパッキン２６を介して載置される平坦な載置面２５が形成され、載置面２５には、載置された外筒４の段部１８が嵌合可能な連通孔２７が形成されている。この載置状態で、先端部２４とバーナ本体２の混合室６とが連通することになる。 On the other hand, the mixing tube 3 is supplied with fuel gas and combustion air as shown in FIG. 4 by press-molding an upper plate 20 and a lower plate 21 made of stainless steel and caulking and joining the outer peripheral edges. A mortar-shaped throat portion 22, a mixing portion 23 provided coaxially with the throat portion 22, and a tip portion 24 connected to the burner body 2 connected to the end of the mixing portion 23. Are integrally formed. A flat placement surface 25 on which the outer cylinder 4 of the burner body 2 is placed via a ring-shaped rubber packing 26 is formed on the upper plate 20 that forms the distal end portion 24. A communication hole 27 into which the stepped portion 18 of the placed outer cylinder 4 can be fitted is formed. In this mounted state, the tip 24 and the mixing chamber 6 of the burner body 2 are communicated.

また、載置面２５への外筒４の載置状態で、内筒５は連通孔２７を貫通して下板２１に当接することになるが、下板２１には、内筒５のネジ孔９を含む下端開口に合わせた形状の貫通孔２８が形成され、その貫通孔２８の周縁に、ネジ孔９に対応した４つの透孔２９，２９・・が周方向で等間隔に形成されている。３０は、先端部２４における下板２１の下面に設けられ、貫通孔２８と同じ内周形状を有する取付リングで、同様にネジ孔９に対応した４つの透孔３１，３１・・が周方向で等間隔に形成されている。すなわち、取付リング３０の下方から透孔３１，２９を夫々貫通させて内筒５のネジ孔９にネジ３２，３２・・をねじ込むことで、下板２１を内筒５にネジ止めするものである。 Further, when the outer cylinder 4 is mounted on the mounting surface 25, the inner cylinder 5 passes through the communication hole 27 and comes into contact with the lower plate 21. A through hole 28 having a shape matching the lower end opening including the hole 9 is formed, and four through holes 29, 29... Corresponding to the screw holes 9 are formed at equal intervals in the circumferential direction on the periphery of the through hole 28. ing. Reference numeral 30 denotes a mounting ring provided on the lower surface of the lower plate 21 at the tip 24 and having the same inner peripheral shape as the through hole 28. Similarly, four through holes 31, 31,... Corresponding to the screw holes 9 are provided in the circumferential direction. Are formed at equal intervals. That is, the lower plate 21 is screwed to the inner cylinder 5 by passing through the through holes 31 and 29 from below the mounting ring 30 and screwing the screws 32, 32... Into the screw holes 9 of the inner cylinder 5, respectively. is there.

以上の如く構成されたコンロバーナ１においては、前述のように混合管３の先端部２４の載置面２５に、ゴムパッキン２６を介してバーナ本体２の外筒４を載置し、取付リング３０の下方から内筒５のネジ孔９へネジ３２をねじ込むことで、図２に示すようにバーナ本体２と混合管３とが連結されるが、この内筒５のネジ孔９に対する混合管３の透孔２９の位置を変えることで、バーナ本体２に対する混合管３の平面視での突出角度を９０°ごとに選択することができる。
従って、同じコンロバーナ１でも、混合管３の向きを変えることでコンロ側のレイアウトに対応した使用が可能となる。また、単一の混合管３でなく、先端部２４に設ける透孔２９の位相が異なるタイプを複数用意して、混合管３のみを交換しても、コンロ側のレイアウトに対応した使用が可能となる。 In the stove burner 1 configured as described above, the outer cylinder 4 of the burner body 2 is mounted on the mounting surface 25 of the distal end portion 24 of the mixing tube 3 through the rubber packing 26 as described above, and the mounting ring As shown in FIG. 2, the burner body 2 and the mixing tube 3 are connected by screwing the screw 32 into the screw hole 9 of the inner cylinder 5 from below, but the mixing tube for the screw hole 9 of the inner cylinder 5 is connected. By changing the position of the three through holes 29, the projection angle of the mixing tube 3 with respect to the burner body 2 in a plan view can be selected every 90 °.
Therefore, the same stove burner 1 can be used corresponding to the layout on the stove side by changing the direction of the mixing tube 3. In addition, a plurality of types with different phases of the through holes 29 provided in the tip 24 instead of a single mixing tube 3 can be prepared, and even if only the mixing tube 3 is replaced, it can be used corresponding to the layout on the stove side. It becomes.

なお、バーナヘッド３３は、図５に示すように、バーナ本体２の内筒５に嵌合可能な筒体３４の上端に、上方へ向かって拡開し、下面外周に放射状のリブ３６，３６・・を所定間隔で複数突設した拡開部３５を形成し、拡開部３５の上方に円盤状のキャップ３７をネジ止め支持した構成で、筒体３４を内筒５に差し込んで拡開部３５のリブ３６をバーナ本体２の外筒４の炎孔形成面７に載置させると、拡開部３５と外筒４との間に混合室６と連通する複数の炎孔３８，３８・・が放射状に形成される。３９は点火電極、４０は熱電対で、夫々外筒４と壁部１１との間に組み付けられて上端を透孔１２から突出させる。 As shown in FIG. 5, the burner head 33 expands upward at the upper end of a cylinder 34 that can be fitted to the inner cylinder 5 of the burner body 2, and radial ribs 36, 36 on the outer periphery of the lower surface. .. A configuration in which a plurality of widened portions 35 projecting at predetermined intervals is formed, and a disk-like cap 37 is screwed and supported above the widened portion 35 so that the cylindrical body 34 is inserted into the inner tube 5 and widened. When the rib 36 of the part 35 is placed on the flame hole forming surface 7 of the outer cylinder 4 of the burner body 2, a plurality of flame holes 38, 38 communicating with the mixing chamber 6 between the expanded part 35 and the outer cylinder 4. .. are formed radially. Reference numeral 39 denotes an ignition electrode, and reference numeral 40 denotes a thermocouple, which are assembled between the outer cylinder 4 and the wall portion 11 so that the upper end protrudes from the through hole 12.

図６，７は、３口のビルトインコンロ５０の手前側の左右に夫々コンロバーナ１，１を使用した例を示すものである。但しここでは、バーナ本体２側のネジ孔９及び混合管３側の透孔２９は、図５のように、図４で説明した位置から略４５°ずれた位相で形成されている。
器体５１内には、バーナ台５２が設けられて、コンロバーナ１はバーナ台５２に取り付けられる。しかし、器体５１内の制御回路に電気的接続される点火電極３９及び熱電対４０との位置が固定となるため、バーナ本体２の向きは左右とも一定となるが、前パネル５３側に設けられる点火機構部５４の位置が異なるため、バーナ本体２に対する混合管３の向きが左右で異なる。そこで、ここではバーナ本体２に対する混合管３の突出角度を互いに９０°変えることで、左右共に同じタイプのコンロバーナ１を使用可能としている。 FIGS. 6 and 7 show examples in which the stove burners 1 and 1 are used on the left and right sides of the three-side built-in stove 50, respectively. However, here, the screw hole 9 on the burner body 2 side and the through hole 29 on the mixing tube 3 side are formed with a phase shifted by approximately 45 ° from the position described with reference to FIG.
A burner base 52 is provided in the body 51, and the stove burner 1 is attached to the burner base 52. However, since the positions of the ignition electrode 39 and the thermocouple 40 that are electrically connected to the control circuit in the container 51 are fixed, the direction of the burner body 2 is fixed on both the left and right sides, but provided on the front panel 53 side. Since the position of the ignition mechanism 54 to be changed is different, the direction of the mixing tube 3 with respect to the burner body 2 is different on the left and right. Therefore, here, by changing the protrusion angle of the mixing tube 3 with respect to the burner body 2 by 90 °, the same type of the burner 1 can be used on the left and right.

また、このビルトインコンロ５０では、奥側のコンロバーナ１ａにおいても、図８に示すように、コンロバーナ１と同様に、アルミダイカストの成形品であるバーナ本体２ａと、アルミ製のプレス成形品である混合管３ａとを組み付けて形成している。よって、コンロバーナ１と同じ構成部には同一の符号を付して重複する説明は省略するが、ここでは内筒５に３つのネジ孔９を設けることによって１２０°ごとに混合管３ａの突出角度を変更可能としている点と、外リブ１７の下面における最も外周側の端部に、最下位置となる突起４１が設けられている点でコンロバーナ１と異なっている。 Further, in the built-in stove 50, as shown in FIG. 8, in the back-side stove burner 1a, as with the stove burner 1, a burner body 2a that is a molded product of aluminum die-casting and an aluminum press-molded product are used. It is formed by assembling a certain mixing tube 3a. Accordingly, the same components as those of the stove burner 1 are denoted by the same reference numerals and redundant description is omitted, but here, by providing three screw holes 9 in the inner cylinder 5, the mixing tube 3a protrudes every 120 °. It differs from the stove burner 1 in that the angle can be changed and a protrusion 41 that is the lowest position is provided at the outermost end of the lower surface of the outer rib 17.

このコンロバーナ１，１ａの組み付け状態では、天板５５に設けた透孔を貫通してバーナ本体２，２ａの上部が天板５５上に突出し、バーナ本体２，２ａの位置決めフランジ１５は、天板５５の裏側でバーナ本体２を位置決めする。天板５５の透孔の内縁には、シールリング５６が嵌着され、そのシールリング５６に、五徳５７と一体のカバーリング５８が被着されて、バーナ本体２，２ａの壁部１１と天板５５との間を覆っている。すなわち、背景技術で述べたように、バーナ本体と天板との間に受け皿を用いないタイプとなっている。５９は、バーナ本体２，２ａ及びバーナヘッド３３を貫通して五徳５７上の鍋底等に当接し、鍋底温度を検出する過熱防止センサである。 In the assembled state of the stove burners 1 and 1a, the upper portions of the burner main bodies 2 and 2a project through the top plate 55 through the through holes provided in the top plate 55, and the positioning flange 15 of the burner main bodies 2 and 2a The burner body 2 is positioned on the back side of the plate 55. A seal ring 56 is fitted to the inner edge of the through hole of the top plate 55, and a cover ring 58 integrated with the virtues 57 is attached to the seal ring 56, so that the wall 11 of the burner body 2, 2 a and the ceiling The space between the plate 55 is covered. That is, as described in the background art, it is a type that does not use a saucer between the burner body and the top plate. Reference numeral 59 denotes an overheat prevention sensor that passes through the burner main bodies 2 and 2a and the burner head 33 and comes into contact with a pan bottom or the like on the virtues 57 to detect the pan bottom temperature.

そして、このコンロバーナ１，１ａにおいては、外筒４の段部１８はゴムパッキン２６の内側及び連通孔２７に嵌合してゴムパッキン２６よりも下方へ突出し、突起１９も連通孔２７を貫通してゴムパッキン２６よりも下方へ突出する。同様に、外リブ１７の水平面１７ｂや突起４１も、ゴムパッキン２６よりも下方に位置している。
よって、噴きこぼれた煮汁等が外筒４の内壁を伝って下方へ垂れることがあっても、ゴムパッキン２６側へ浸入することなく段部１８及び突起１９の下端から混合室３内に落下する。同様に外筒４の外面側では、外筒４の外壁を伝った煮汁等は外リブ１７を介してさらに低い水平面１７ｂや突起４１側へ流れて落下し、ゴムパッキン２６の位置にとどまらない。
従って、煮汁等によるゴムパッキン２６の腐食を効果的に防止することができる。 In the stove burner 1, 1 a, the step portion 18 of the outer cylinder 4 is fitted to the inside of the rubber packing 26 and the communication hole 27 and protrudes downward from the rubber packing 26, and the protrusion 19 also penetrates the communication hole 27. Then, it protrudes downward from the rubber packing 26. Similarly, the horizontal surface 17 b and the protrusion 41 of the outer rib 17 are also located below the rubber packing 26.
Therefore, even if the spilled broth or the like hangs down along the inner wall of the outer cylinder 4, it falls into the mixing chamber 3 from the lower end of the step portion 18 and the protrusion 19 without entering the rubber packing 26 side. . Similarly, on the outer surface side of the outer cylinder 4, boiled juice or the like that has traveled along the outer wall of the outer cylinder 4 flows and falls to the lower horizontal surface 17 b or the protrusion 41 side via the outer rib 17, and does not stay at the position of the rubber packing 26.
Therefore, the corrosion of the rubber packing 26 due to the broth or the like can be effectively prevented.

さらに、炎孔３８にゴミが詰まったり、バーナヘッド３３をバーナ本体２上の誤った位置に組み付けたりすることで、バック燃焼を生じさせることがあっても、外リブ１７及び内リブ８によってバーナ本体２の表面積や剛性が増加しているため、バーナ本体２の温度上昇が抑えられ、変形したり溶融したりするおそれがなくなる。また、壁部１１と外筒４及び内筒５が外リブ１７と内リブ８とを介して連続状に繋がるため、ダイカスト成形の際のいわゆる湯流れが外リブ１７及び内リブ８を介して良好に行われる。 Furthermore, even if the flame hole 38 is clogged with dust or the burner head 33 is assembled at an incorrect position on the burner body 2 to cause back combustion, the outer rib 17 and the inner rib 8 can burn the burner. Since the surface area and rigidity of the main body 2 are increased, the temperature rise of the burner main body 2 is suppressed, and there is no possibility of deformation or melting. Further, since the wall portion 11 and the outer cylinder 4 and the inner cylinder 5 are continuously connected via the outer rib 17 and the inner rib 8, a so-called hot water flow at the time of die-casting is formed via the outer rib 17 and the inner rib 8. Done well.

このように、上記形態のコンロバーナ１，１ａによれば、バーナ本体２をダイカスト成形で作製すると共に、バーナ本体２に平面視放射状の外リブ１７を設けたことで、ダイカスト製であっても温度上昇による変形や溶融を効果的に防止でき、耐久性の高いコンロバーナ１，１ａが得られる。
特にここでは、外リブ１７を外筒４の外周と壁部１１の内周との間に設けているため、壁部１１を有したものであっても、ダイカスト成形時に外リブ１７を介して外筒４と壁部１１との間の湯流れが良好に行われる。
さらに、外筒４の内周と内筒５の外周との間に平面視放射状の内リブ８を設けているため、内筒５を有した場合でも同様に変形や溶融が効果的に抑えられ、良好な湯流れも維持できる。 Thus, according to the above-described stove burners 1 and 1a, the burner body 2 is produced by die casting, and the burner body 2 is provided with the outer ribs 17 that are radial in plan view. Deformation and melting due to temperature rise can be effectively prevented, and the durable burner 1, 1a can be obtained.
In particular, since the outer rib 17 is provided between the outer periphery of the outer cylinder 4 and the inner periphery of the wall portion 11, even if the wall portion 11 is provided, the outer rib 17 is interposed via the outer rib 17 during die casting. The hot water flow between the outer cylinder 4 and the wall portion 11 is favorably performed.
Further, since the radial ribs 8 are provided between the inner circumference of the outer cylinder 4 and the outer circumference of the inner cylinder 5, deformation and melting can be effectively suppressed even when the inner cylinder 5 is provided. Good hot water flow can be maintained.

なお、外リブ及び内リブの数や形状は上記形態に限らず、適宜変更可能である。また、バーナ本体に内筒が設けられず、混合管の先端部に内筒が設けられる形態であっても本発明の採用は可能である。
さらに、壁部の形態も上記形態に限らず、周方向や下方への長さ等は変更して差し支えない。
一方、混合管においても、プレス成形した上板と下板とで形成する形態に限らず、ダイカスト成形等によって一体に形成する等、適宜変更して差し支えない。 In addition, the number and shape of an outer rib and an inner rib are not restricted to the said form, It can change suitably. Moreover, even if the inner cylinder is not provided in the burner body and the inner cylinder is provided at the tip of the mixing tube, the present invention can be adopted.
Furthermore, the form of the wall portion is not limited to the above form, and the circumferential direction, the length in the downward direction, and the like may be changed .
On the other hand, the mixing tube is not limited to the form formed by the press-formed upper and lower plates, and may be appropriately changed, for example, integrally formed by die casting or the like.

そして、ダイカスト成形の材料も、アルミニウム合金以外に、亜鉛合金やマグネシウム合金、銅合金等が採用可能である。
In addition to the aluminum alloy, a zinc alloy, a magnesium alloy, a copper alloy, or the like can be employed as the material for die casting.
