Description

【0001】
【発明の属する技術分野】
本発明は、ガス調理器具に搭載するこんろバーナに関する。
【0002】
【従来の技術】
従来、この種のこんろバーナは、図7に示されているように、バーナボディ1上面に、バーナキャップの環状炎口列の一部に点火用炎口及び失火検出用炎口を有する副燃焼室を嵌合させるための凹部2及び副燃焼室に円周方向にバーナキャップの凸部と嵌合する嵌合孔3を設けて、バーナキャップを嵌合載置する構成にしていた。
【0003】
【発明が解決しょうとする課題】
しかしながら、上記の構成では、バーナキャップをバーナボディ1に載せる際、バーナキャップの環状炎口列の一部に、点火用炎口及び失火検出用炎口を有する副燃焼室を嵌合させるための凹部及び副燃焼室に、円周方向にバーナキャップの凸部と嵌合する嵌合孔以外の位置で載せられて使用されることがあり、その為に燃焼不良になったり、他の部品が焼損したりして安全性の面で必ずしも十分とは言い難かった。
【0004】
本発明は、バーナキャップとバーナボディの嵌合が的確に、スムーズにおこなわれて、誤嵌合が生じない安全性の提供を目的とする。
【0005】
【課題を解決するための手段】
この課題を解決するために本発明は、バーナキャップをバーナボディに載せる際、バーナキャップの誤嵌合の状態を使用者が目視で明確に確認できるように、バーナキャップを載せて回して嵌合しやすいように、また、嵌合位置以外での嵌合が生じないように構成したものである。これにより、誤嵌合が生じない安全性が得られる。
【0006】
【発明の実施の形態】
本発明の請求項1に記載の発明は、上面に混合ガス供給用の開口を複数設け、その外側に段部を介して炎口載置面を設けた環状頭部を有するバーナボディに、環状に炎口列を設け環状炎口列の一部に点火用炎口及び失火検出用炎口を有するバーナキャップを載置して、前記バーボディとバーナキャップで副燃焼室及び主炎口を形成し、前記副燃焼室に配置した点火用電極により点火し、隣接した失火検出用炎口に火移りさせた後、環状に配列した主炎口に火移りさせて燃焼を行うようにしたこんろバーナであって、前記バーナキャップには円周方向に間隔をあけて形状の異なる複数個の凸部を設けるとともに、前記バーナボディの環状頭部上面には前記凸部が嵌合する嵌合孔を設け、前記嵌合孔は少なくとも外周の一部が前記混合ガス供給用開口の外周より外側に位置する箇所に配置したバーナである。そして、複数個の形状の異なる凸部にて誤嵌合を防止し、嵌合が正規に行われない状態は複数個の凸部にてバーナキャップがバーナボディの上面より黙視で確認できる。また、バーナキャップをバーナボディに載置する際、バーナキャップを回して嵌合位置決めを行うとき、段部が凸部の外周のガイドになり、スムーズに回して嵌合位置決めを行うことができる。
【0008】
請求項に記載の発明は、上面に混合ガス供給用の開口を複数設け、その外側に段部を介して炎口載置面を設けた環状頭部を有するバーナボディに、環状に炎口列を設け該環状炎口列の一部に点火用炎口及び失火検出用炎口を有するバーナキャップを載置して、前記バーボディとバーナキャップで副燃焼室及び主炎口を形成し、前記副燃焼室に配置した点火用電極により点火し、隣接した失火検出用炎口に火移りさせた後、環状に配列した主炎口に火移りさせて燃焼を行うようにしたこんろバーナであって、前記バーナキャップには円周方向に間隔をあけて形状の異なる複数個の凸部を設けるとともに、前記バーナボディの環状頭部上面には前記凸部が嵌合する嵌合孔を設け、前記嵌合孔は少なくとも周方向もしくは径方向に対して前記混合ガス供給用開口より大きくしたこんろバーナである。そして、バーナボディの上面のガス供給用の開口バーナキャップの凸部の先端形状よりも小さくしたものであり、バーナキャップの凸部が正規の位置の嵌合孔以外の場所にはいりこまないようにして、誤嵌合を防止したものである。
【0009】
以下、本発明の実施例について、図1から図6を用いて説明する。
(実施例1)
図1、図2、図3において、1aはプレス成形されたバーナボディで、ノズル4から供給されるガスは、混合管Mで空気と混合されて、バーナキャップ5aとバーナボディ1aとで形成された点火炎口部6で点火用電極7により点火され、さらに隣接された失火検出用炎口8に火移りし、さらに環状に配列された主炎口9に火移りする。
【0010】
バーナキャップ5aとバーナボディ1aの嵌合は、点火炎口部6および失火検出用炎口部8を、バーナキャップ5aの環状炎口部の突起形状10、11にてはさみ形成する副燃焼室12を、バーナボディ1aの上面の凹部2に嵌合している。
【0011】
さらに副燃焼室12より離れた円周方向に形状の異なる凸大部13、凸小部14にてバーナボディ1aの嵌合孔3a、3bと嵌合している。凸大部13と凸小部14の間隔は、バーナボディ1aの副燃焼室12の凹部2の空間2の幅2aよりも大きくしている。
【0012】
上記構成において、バーナキャップ5aとバーナボディ1aの嵌合は確実であり、しかも、副燃焼室12の嵌合部以外に複数の異なる凸部の凸大部13、凸小部14との嵌合のため、嵌合が正規に行われない場合でも、一つの嵌合用の凸部がバーナボディ1aの凹部2の空間2aにはまっても、複数の突起形状10、11および凸大部13、凸小部14のどれかがバーナボディ1aの上面より浮いて誤嵌合が目視にて明確にわかる。
【0013】
図3、図4において、バーナキャップ5aを載せるバーナボディ1aの炎口面15と上面16とで形成される段17をガイドとして、バーナキャップ5aの凸大部13と凸小部14が、バーナボディ1aの上面16のうえに載せられている状態を示している。
【0014】
ガス通過口の開口18の外周18aの中心からの長さRよりも、バーナキャップ5aの凸大部13と凸小部14の中心からの外周までの長さを大きくすることで、バーナキャップ4の凸大部13と凸小部14は、ガス通過口の開口18にはまりこむことがない。
【0015】
バーナボディ1aの上面を、段17をガイドにしてバーナキャップ5aを回して、嵌合の位置にくれば、簡単にバーナキャップ5aをバーナボディ1aに嵌合することができる。つまり、嵌合孔3a、3bは斜線を施した外側の部分が開口18の長さRより大のために、凸大部13と凸小部14は開口18にははいれない。
【0016】
(実施例2)
図5及び図6において、バーナボディ1bのガス通過口の開口18b等の形状は、バーナキャップ5bの凸大部13c、凸小部14dの大きさよりも嵌合的に小さくしたものである。開口18bは横に狭く、開口18dは縦に狭く、開口18eは嵌合孔3cに比べて斜線部がない。
【0017】
したがって、バーナキャップ5bの凸大部13c、凸小部14dは、バーナキャップ5bを嵌合するためにバーナボディ1bに載せて回してもバーナボディ1bのガス通過口の開口18b、18c、18d、18eにはまりこむことなく、バーナボディ1bの上面を回すことができ、嵌合の位置にくれば簡単に嵌合することができる。
【0018】
【発明の効果】
以上のように本発明によれば、バーナキャップをバーナボディに載せる際、バーナキャップの誤嵌合の状態を使用者が目視で明確に確認できるように、バーナキャップを載せて回して嵌合しやすいように、また、嵌合位置以外での嵌合が生じないように構成したものである。これにより、安全性が確保されるという有利な効果が得られる。
