Description

【０００１】
【発明の属する技術分野】
本発明は、システムキッチン等のワークトップに設けた開口に吊持して設置するドロップインコンロに関するものである。
【０００２】
【従来の技術】
従来より、調理台のワークトップにドロップインコンロを設置したシステムキッチンが知られている。このドロップインコンロは、ガスバーナを収容したコンロ本体の上面をガスバーナが臨む開口を有する天板で覆ってなっており、コンロ本体の周壁上端のフランジをワークトップの上面に係止することにより、ワークトップの開口に吊持される。
【０００３】
このようなドロップインコンロでも、コンロ本体の前面がワークトップの下方で使用者側に露出するものでは、その前面に操作部を設けると共に、前面に通気口などを形成することができるので、燃焼用空気や冷却用空気を取り入れることができる。
【０００４】
しかし、コンロ本体の前面がワークトップの下方で使用者側に露出せず、操作部を天板上に設けるものでは、操作部近傍に通気口を設けることはできない。また、コンロ本体内の熱が外部に及ぶことを極力防止するために、コンロ本体は、その密閉性を高めている。このためコンロ本体の周囲からの燃焼用一次空気の取り入れができない。
【０００５】
そこで下記特許文献１に見られるように、天板周囲の立ち下がり壁に開口を設けて、これを通気口とするドロップインコンロが知られている。特許文献１によれば、密閉性の高いコンロ本体でも通気口を介して燃焼用空気のコンロ本体への取り入れができる。しかし、このものでは、燃焼用空気を十分に確保するために、天板周囲の立ち下がり壁を高くして開口面積を十分に確保する必要があるが、天板を薄くしてデザイン性を高める場合には、天板の立ち下がり壁を小さくしなければならず、そこに通気口を設けても十分な通気量を確保することが困難となる不都合があった。

【発明が解決しようとする課題】
かかる不都合を解消して、本発明は、十分な燃焼用空気を確保することができると共に、外観の優れたドロップインコンロを提供することを目的とする。
【０００９】
【課題を解決するための手段】
かかる目的を達成するために、本発明は、ガスバーナを収容し上面に開口を備えるコンロ本体と、該コンロ本体の上面開口を覆う天板とからなり、該コンロ本体をワークトップに設けた開口に吊持させるドロップインコンロにおいて、前記天板の後部に、コンロ本体内部への通気口を設けると共に、該通気口の前縁側から通気口の上方直近を流れる気流を遮断するフードを設け、前記通気口は、該天板の上面に対して上向きに設けられ、前記フードは、通気口の前縁から後方に向けて上方に傾斜した傾斜部と、該傾斜部の前端部に形成されて通気口の前縁を閉じる垂直壁と、該傾斜部の後端部の下方を開放して通気口に連なる空気取り入れ部と、該傾斜部の両側端に形成された一対の側壁とを一体に備えて、前記天板の通気口に取り外し自在に設けられていることを特徴とする。
【００１０】
本発明では、通気口を天板の周囲の垂下壁ではなく天板の上面に設けるので、通気口を大きな面積に形成して設けることができる。しかし、ドロップインコンロは殆どの場合、台所の壁の前方に設置されるものであり、バーナの燃焼により後壁面に沿った風の流れが生じることにより、コンロ前方から通気口上を後方に流れる風の流れが生じ、このままでは、通気口上の直近を流れる空気の流れに邪魔されて、通気口からの燃焼用空気の取り入れが困難である。そこで、本発明では、通気口にフードを設けて、通気口上の直近を流れる空気の流れを遮蔽するので、コンロ前方から通気口上を後方に流れる風の流れがあっても影響されずに、空気を通気口から吸い込むことができて、十分な空気をコンロ本体内に供給することができるので、良好な燃焼を実現できる。また通気口およびそれを覆うフードは天板の後部にあるので、コンロを前方から見たときの見栄えが損なわれることがない。
また、前記フードは、通気口の前縁から後方に向けて上方に傾斜した傾斜部と、該傾斜部の前端部に形成されて通気口の前縁を閉じる垂直壁と、該傾斜部の後端部の下方を開放して通気口に連なる空気取り入れ部と、該傾斜部の両側端に形成された一対の側壁とを一体に備えて通気口の上方を覆うので、遮風効果および異物の通気口への落入防止効果上もよい。そして、フードは傾斜部が通気口の前縁から後方に向けて上方に傾斜する形状なので、形状も大きくならずよい。
【００１１】
また、本発明は、前記天板の後部に、コンロ本体内部への通気口を設けると共に、該通気口の前縁側から通気口の上方直近を流れる気流を遮断するフードを設け、該フードを後方に向けて上昇する傾斜状とし、該フードの傾斜角度を変えることができる角度可変装置を備えたことを特徴とする。コンロと後壁面との間隔によっては空気の流れが異なり、通気口からの空気の吸入状態が異なって十分な空気の吸入ができなくなることがあるが、フードの傾斜角度を変えられるようにしておけば、後壁面との間隔にあわせてフードの角度を調節することにより、十分な空気の吸入を行わせることができる。
【００１２】
本発明によれば、前記天板を金属板、例えば厚さ数ｍｍのアルミ板とすることができ、該金属板の後部に開口を設けて、それを前記通気口とすることができる。
【００１３】
また、本発明は、前記天板が金属板であるとき、該金属板の後端縁から所定距離を存した位置に該金属板の後端縁に沿って延びる切れ目を設け、該切れ目を介して前方側を折り起こした折り起こし片を前記フードとする。これにより、該金属板に前記通気口と前記フードとを同時に形成できる。この場合、具体的には、天板の後部側に方形の前側の辺を除く３辺の切れ目を形成し、該切れ目を介して天板の一部を折り起こす。あるいは天板の後部側に１辺の切れ目を形成して絞りつつ折り起こしてもよい。
また、天板の後縁の折り起こし片によって、天板の後部にフードを形成し、フードの下方に位置するコンロ本体後部を開放して通気口を形成してもよい。即ち、前記天板が金属板であるとき、該金属板の後辺を全幅にわたり折り起こすことにより天板の後端縁をコンロ本体から離間させてコンロ本体内部への通気口とすると共に、該折り起こして形成された折り起こし片によって該通気口の前縁側から通気口の上方直近を流れる気流を遮断するフードを形成することができる。
【００１４】
本発明において、前記天板を厚手の金属板としたとき、前記フードは他部より肉薄に形成されていることが好ましい。これにより、前記フードの折り起し等の加工を極めて容易とすることができる。また、該金属板におけるフードの折り起こし時の折り曲げ位置に沿って折り溝を設けてもよい。これによっても、前記フードの折り起こし等の加工を極めて容易とすることができる。
【００１５】
また、本発明においては、前記フードの後端縁に垂下形成された連結部を、前記コンロ本体の後部から前記通気口内に起立する被連結部に連結することが好ましく、更に、前記被連結部は、コンロ本体の周縁に備えるフランジの一部を切り起こして形成されていることが好ましい。こうすることによって、前記天板をコンロ本体に強固に連結することができる。そして、連結部材や連結部はフードの後ろ側に隠されてコンロの前方位置からは見えなくすることができるので、天板の外観を良好に保って天板とコンロ本体とを連結することができる。
【００１６】
また、本発明においては、前記天板を、板体と金属製の額縁状の枠体とによって構成してもよい。この場合には、該枠体は前記板体を設置する設置部と前記通気口とを画成する仕切枠材を備えて、該仕切枠材に前記フードを一体に形成することが好ましい。これにより、枠体に通気口とフードとを設けることができ、板体に対する曲げ加工等が不要となるので、例えば、ガラス製の板体や厚手の金属板を容易に採用することができる。そして、前記コンロ本体と前記枠体とを連結する連結部材を設け、該連結部材の下端部を前記コンロ本体の後部側に連結し、上端部を前記フードの下方又は後方において前記枠体に連結することが好ましい。こうすることによって、連結部材の上端部はフードの下方や後方に隠されるので、コンロの前方位置からは見えず、天板の外観を良好に保って天板とコンロ本体とを連結することができる。
【００１７】
また、本発明において、連結部をフードの後端縁に垂下形成してもよい。該連結部は、天板の後端縁を折り起こしてフードを形成した場合、枠体の一部にフードを形成した場合の何れにも採用することができる。
【００１８】
また、前記フードは、後方に向けて上昇する傾斜状とすることが好ましい。これにより、通気口の上方をフードにより覆うことができ、遮風効果および異物の通気口への落入防止効果上もよく、形状も大きくならずよい。
【００１９】
【発明の実施の形態】
先ず、本発明の第１の実施形態について図１乃至図５を参照して説明する。図１は本発明のドロップインコンロの第１の実施形態を示す斜視図、図２は図１のコンロのフードを取り除いて示す斜視図、図３は図１のコンロの一部の説明的断面図、図４は図１のコンロ本体の上面を覆うガラス天板の枠体を示す平面図、図５は図１のコンロ本体内のバーナ等の配置概要を示す平面図である。
【００２０】
図１に示すように、ドロップインコンロ１０は、ガスバーナ１１を収容するコンロ本体２０と、その上面を覆う天板３０とによって構成されている。天板３０は、板体としての耐熱性ガラス板（セラミックガラス）３１とその周囲のトップ枠３５からなり、ガラス板３１の前後方向略中央位置に設けた左右の窓穴３２に、コンロ本体２０内に収容した内炎式のガスバーナ１１が臨んでいる。窓穴３２の周囲の耐熱性ガラス板３１には五徳１２が載置される。ガラス板３１の前寄りの中央部位置には、左右のガスバーナ１１の点火、火力調整および消火操作を行う点火つまみ１３がそれぞれ設けられている。
【００２１】
本実施形態によれば、図２に示すように、天板３０の後部にその略全幅にわたって燃焼用一次空気を吸気可能とする通気口３３が設けれている。このように、通気口３３が天板３０の後部にあれば、コンロ１０を前方から見たときの見栄えが損なわれることが少なく、ここに格子状のガードを設ければ異物の落入もない。しかし、後述するように、ドロップインコンロは殆どの場合、台所の壁の前方に設置されるものであり、バーナの燃焼により壁に沿った上昇の風の流れが生じ、それにより天板上には前方から後方に風の流れが生じ、通気口３３上の直近を後方に流れる空気の流れに影響されて、通気口３３からの燃焼用空気の取り入れが困難である。そこで、図１に示すように、通気口３３の前縁にコンロ前方から通気口３３上の直近を後方に流れる空気の流れを妨げる遮風体としてのフード４０が設けられている。
【００２２】
コンロ本体２０は、前面がワークトップ２の下方で使用者側に露出することなくコンロ本体２０の全周で埋設される上面開放の薄型の矩形状の箱体からなり、操作部は天板上に設けられている。
【００２３】
そして、コンロ本体２０は、図３に示すように、システムキッチンのワークトップ２に設けられた開口３の周縁に、本体２０の周壁２１の上端に折曲形成されたフランジ２２をワークトップ２に係止させることにより、ワークトップ２の開口３に吊持して設置されている。コンロ本体２０の周壁２１には、ワークトップ２の開口３周囲の端面に当接してコンロ本体２０のガタ付きを防ぐために、突起２１ａが設けられている。またフランジ２２の先端には、ワークトップ２の上面からの水や煮汁等のコンロ本体２内への侵入を防止しするためにパッキン２２ａが取付けられている。
【００２４】
コンロ本体２０内には、図５に示すように、前後方向中央位置に前記のガスバーナ１１が左右に設置され、各ガスバーナ１１にはコンロ本体２０内前部に設けたそれぞれのコック１４からのガス配管１５ａが接続されている。コック１４には、コンロ本体２０底部のインレット１５ｂからガスを供給するマニホルド１５が接続され、またコック１４には、前記の点火つまみ１３を取り付ける操作軸１４ａが設けられている。図５において、１６はバーナ１１の失火を検出するサーモカップルで、リード線１６ａによりコック１４に接続されている。
【００２５】
前記トップ枠３５は、図４において、長尺の前後２本の枠材３６、３６と短尺の左右２本の枠材３７、３７とを矩形状に組み付けることで額縁状の枠を形成し、その後部寄りの位置には短尺の枠材３７、３７間に仕切枠材３８が差しわたされている。これにより、前側の枠材３６、左右の枠材３７、３７および仕切枠材３８の間にガラス板３１の設置領域が形成される。同時に、仕切枠材３８、左右の枠材３７、３７および後側の枠材３６の間に通気口３３が形成される。
【００２６】
前後左右の各枠材３６、３７は、垂直壁３６ａ、３７ａの下端から内側に水平に突出した縁部３６ｂ、３７ｂと垂直壁３６ａ、３７ａの上端から外側に下る向きにカールした上に凸のフランジ部３６ｃ、３７ｃとを有する断面構造に形成されている。仕切り枠材３８は、垂直壁３８ａの下端から前方に水平に突出した縁部３８ｂと後方に水平に突出する縁部３８ｃとを有する断面構造に形成されている。これら各枠材３６、３７、３８は、それぞれアルミニウムの押出し成形によって一体に形成されている。
【００２７】
長短の枠材３６と３７とは、前後の枠材３６の縁部３６ｂにおける両端に設けられた逆三角形状の頭部３６ｂ１と左右の枠材３７の縁部３７ｂにおける両端に設けれた三角形形状の凹部３７ｂ１とをかしめ嵌合することで連結されている。同様に、短尺の枠材３７の途中に設けられた三角形状の凹部３７ｂ２と仕切枠材３８の縁部３８ｂにおける両端に設けられた逆三角形形状の頭部３８ｂ１とをかしめ嵌合することにより、枠材３７と３８とが組み付けられている。
【００２８】
図２及び図４に示すように、ガラス板３１の支持部は、前側の枠材３６、左右の枠材３７、３７および仕切枠材３８の水平の縁部３６ｂ、３７ｂ、３７ｂ、３８ｂとで形成される矩形状の支持枠辺で構成され、この上にガラス板３１が載置される。載置されたガラス板３１と枠材３６、３７、３７、３８の垂直壁３６ａ、３７ａ、３７ａ、３８ａとの間にはシリコンコーキング材３９が充填され、ガラス板３１をトップ枠３５に位置ずれしないようにしっかりと保持すると共に水密性が確保される。天板３０の後の枠材３６には、互いに間隔を開けて２箇所のねじ穴３６ｄが形成されている。そして、該ねじ穴３６ｄを介してコンロ本体２０のフランジ２２に成形した螺着突起２２ｂにねじ３６ｅが螺着され、これによって天板３０がコンロ本体２０に位置決めされる。その状態で枠材３６、３７のフランジ部３６ｃ、３７ｃは、コンロ本体２０のフランジ２２を覆ってワークトップ２の上面に接地する。
【００２９】
通気口３３は、仕切枠材３８の垂直壁３８ａと、左右の枠材３７、３７および後側の枠材３６の水平の縁部３７ｂ、３７ｂおよび３６ｂとで形成される穴部として、天板３０の後部に天板３０の略幅方向一杯の長さに設けられている。天板３０の通気口３３の下には上面開放のコンロ本体２０の後部が位置して、通気口３３がコンロ本体２０内に連通する。本実施形態では、このように、通気口３３を天板３０の周囲の垂下壁ではなく、天板３０の上面に設けることにより、大面積の通気口３３が形成され、十分な燃焼用一次空気を取り入れることができる。
【００３０】
通気口３３には前記のフード４０が設けられている。フード４０は、図２および図３に示すように、通気口３３の前縁部から後方に向けて上方に傾斜した傾斜部４０ａを備えている。本実施形態では、フード４０の前端部４０ｂが垂直壁に形成され、仕切枠材３８の垂直壁３８ａの後面に接してフード４０の前端部４０ｂで通気口３３の前縁部３３ａを閉じ、フード４０の後端部４０ｄの下は開放されて通気口３３に連なる空気取り入れ部となっている。フード４０の後端部４０ｄは外側に水平に折曲されており、前記前端部４０ｂと共に長尺のフード４０が補強されている。
【００３１】
また傾斜部４０ａの両側端には側壁４０ｃが形成され、左右の枠材３７の水平の縁部３７ｂがこの側壁４０ｃの下端部の着座部として機能し、フード４０が通気口３３に取り外し自在に配設される。なお、図３のように、仕切枠材３８の垂直壁３８ａの後方に後方縁部３８ｃをフード４０の板厚より少し長めに突出させておけば、フード４０の前端部４０ｂの着座部として機能し、フード４０をより安定して通気口３３に配設できる。なお、このフード４０は傾斜部４０ａ、前端部４０ｂ、両側壁４０ｃをアルミ板で折り曲げ加工で一体的に形成した。
【００３２】
このフード４０の傾斜部４０ａの傾斜は、フード４０の空気吸入部となるフード４０の後端部４０ｄと後側の枠材３６の上端との間隔を十分に取ることができるようにすればよく、一般に２０度〜６０度程度がよい。傾斜角度が小さすぎると、空気吸入部の間隔を十分に取ることができず、傾斜角度が大きすぎると見栄えが悪くなる。本例では、傾斜部４０ａの傾斜角度を２５度として、後側の枠材３６の垂直壁３６ａ上端と後端部４０ｄとの間隔を１４ｍｍに確保した。
【００３３】
図３において、バーナ１１でのガスの燃焼時、ドロップインコンロ１０の上面での空気の流れは、後壁面４による上昇流のためコンロの前部から通気口３３上を後方に向う。このため、単に天板３０後部に通気口３３を大面積に設けても、コンロ前方から通気口３３上の直近を流れる空気の流れに邪魔されて、通気口３３の周囲から通気口３に向けて空気が入りづらく、コンロ本体２０内への燃焼用一次空気の吸入が困難になる。
【００３４】
これに対し、通気口３３にフード４０を設けておけば、コンロ前部から通気口３３上の直近を後方に流れる空気の流れをフード４０の前面で遮蔽し、乃至上方に反らして防ぐことができ、フード４０の背面では通気口３３上の直近を後壁面４に向けて流れる空気の流れがなくなる。したがって、後壁面４に向かう空気の流れに影響されずに空気が通気口３３から吸引されるので、大面積の通気口３３から十分な空気をコンロ本体２０内に供給することができ、良好な燃焼を行わせることができる。なお、フード４０の形態として、通気口３３の前縁に立壁状に設けてもよいが、特にフード４０を通気口３３を覆うような覆部を備える構成や、覆部を兼ねて前縁から後方に向けて上昇するように傾斜すれば、遮風効果および異物の通気口への落入防止効果上もよい。
【００３５】
次に、本発明の第２の実施形態について図６を参照して説明する。図６は第２の実施形態の要部を示す説明的断面図である。
【００３６】
ドロップインコンロ１０と後方の壁面４との間隔によっては空気の流れが異なり、その結果、通気口３３からの空気の吸入状態が異なって十分な空気を吸入できなくなることがある。そこで、本実施形態では、フード４２の傾き角度が調節可能とされている。フード４２はアルミニウム板からなっており、フード４２の前部両側に折曲形成した支持部４２ｂを左右の枠材３７に設けた軸４２ａに軸支することで、フード４２の角度可変装置が形成されている。
【００３７】
これにより、後壁面４との間隔にあわせてフード４２の角度を調節することにより、十分な空気の吸入を行わせることができる。なお、第２の実施形態におけるその他の構成は、図１乃至図５を参照して説明した第１の実施形態と基本的に同じである。
【００３８】
次に、本発明の第３の実施形態について図７乃至図１１に基づいて説明する。図７は第３の実施形態における天板を示す平面図、図８は図７のコンロ後半部を示す説明的断面図、図９はコンロ本体と天板との連結部材を示す説明的分解斜視図、図１０及び図１１は連結部材の変形例を示す説明的断面図である。
【００３９】
第３の実施形態におけるフード４５ｃは、トップ枠３５Ａの仕切枠材４５と一体とした。該フード４５ｃは、仕切枠材４５の垂直壁４５ａの上端から後方に向けて上方に湾曲して傾斜している。４５ｂは垂直壁４５ａの下端から水平に前方に突出した縁部である。４６は支え板で、フード４５ｃの両端部近くと中央部の３箇所に設けた。支え板４６は後の枠材３６の水平の縁部３６ｂに下端の折曲部４６ａをリベット４６ｂ（図７及び図９示）により連結する。トップ枠３５Ａの構成は図４のトップ枠３５と、その仕切枠材３８を除いて同じである。なお、仕切枠材４５とフード４５ｃが一体のため、仕切枠材４５は最後に両側の枠材３７に取り付けられる。また、図７においては図示を省略したが、図８及び図９に示すように、トップ枠３５Ａと本体２０とは連結部材２０ａ１によって連結されている。
【００４０】
連結部材２０ａ１は、支え板４６の後縁の一側に張出形成された舌片４６ｃと本体２０の底部とを連結している。即ち、連結部材２０ａ１の下端に水平に設けられた下部連結部２０ａ２が本体２０の底部に螺着され、連結部材２０ａ１の上端に起立して設けられた上部連結部２０ａ３がねじｎを介して支え板４６の舌片４６ｃに螺着されている。こうすることにより、コンロ前方からは連結部材２０ａ１の上部連結部２０ａ３と支え板４６の舌片４６ｃとの連結部分がフード４５ｃに隠されて見えず、天板の外観を損ねることがない。しかも、支え板４６の舌片４６ｃの後方にはねじｎが露出しているので、フード４５ｃが邪魔になることなく連結作業を容易に行なうことができる。
【００４１】
また、第３の実施形態においては、フード４５ｃによって後の枠材３６が前方から見えない位置にあるので、図１０に示すように、連結部材２０ｂ１の上部連結部２０ｂ２を後の枠材３６にねじｎにより連結するようにしてもよい。更にそれ以外には、図１１に示すように、後の枠材３６の水平の縁部３６ｂに連結板３６ｆを設け、この連結板３６ｆに連結部材２０ｃ１の上部連結部２０ｃ２をねじｎにより連結してもよい。連結板３６ｆのねじ止め部３６ｇは、フード４５ｃの後部側の開放方向に向って傾斜して形成されており、連結部材２０ｃ１の上部連結部２０ｃ２は、連結板３６ｆのねじ止め部３６ｇに対応してその裏面に当接する形状に形成されている。これにより、連結部材２０ｃ１の上部連結部２０ｃ２と連結板３６ｆのねじ止め部３６ｇとの連結部分がフード４５ｃによって隠されてコンロ１０の前方からは見えず天板の外観を損ねることがない。しかも、フード４５ｃの後方からねじｎの螺着作業が行なえるので、フード４５ｃが邪魔になることなくフード４５ｃの下方における連結作業を容易に行なうことができる。
【００４２】
なお、本例では、後の枠材３６と左右の枠材３７とは、これらの水平の縁部３６ｂ、３７ｂ間にＬ字金具４７をリベット止めして固定したが、もちろん、第１の実施形態と同様、これらの先端部の凹凸によるかしめで組み付けてもよい。
【００４３】
また、第３の実施形態では、フード４５ｃを仕切枠材４５と一体に形成したので、フード４５ｃの作製を省力化することができる。
【００４４】
以上の第１〜第３の実施の形態では、いずれも、内炎式のガスバーナ１１を備えたドロップインコンロについて説明したが、ガスバーナは外炎式であってもよい。また板体としてガラス板の代わりに、金属板例えば板厚数ｍｍのアルミ板を採用することもできる。
【００４５】
次に、本発明の第４の実施形態を図１２乃至図１４に基づいて説明する。図１２は本発明のドロップインコンロの第４の実施形態を示す斜視図、図１３は図１２のコンロのフードを取り除いて示す斜視図、図１４（ａ）は図１２のコンロ後半部を示す説明的断面図、図１４（ｂ）は図１２のコンロにおけるフードの一部の斜視図である。
【００４６】
第４の実施形態のドロップインコンロ１０は、金属板としてのアルミトップコンロであり、コンロ本体２０の上面を覆う天板５０が板厚数ｍｍのアルミニウムの一枚板からなっている。この天板５０の後部には、図１乃至図５で示した第１の実施の形態と同様なフード６０が設けられており、天板５０の後部に設けた通気口６３の上方を覆っている。第４の実施形態では、図１３に示すように、通気口６３は天板５０の後辺から１５ｍｍの後縁を残して切削加工により形成した。ガラス板で幅狭の後縁を残して開口を形成することは困難であるが、板厚数ｍｍのアルミニウム板であればガラス板と同様の重厚感を得ることができると共に、開口を形成する加工が容易である利点、及びトップ枠を不要とすることができる利点がある。
【００４７】
図天板５０には、図１２及び図１３に示すように、前後方向略中央位置とその間の後方寄りの位置との３箇所に窓穴５２が設けられ、その左右の窓穴５２に、コンロ本体２０内に収容した大バーナ５１ａとその内側の小バーナ５１ｂとを備える親子型の外炎式ガスバーナ５１が臨んで上方に露出され、後方寄りの窓穴５２に外炎式の中ガスバーナ５３が臨んで上方に露出されている。各バーナ５１、５１、５３の周囲にはそれぞれ五徳１２が天板５０に載置されている。また天板５０の前寄りの中央部位置には、これらガスバーナ５１、５１、５３の点火、火力調整および消火操作を行う点火つまみ１３がそれぞれ設けられている。
【００４８】
コンロ本体２０は、第１の実施形態と同様に、ワークトップ２の開口３に吊持される。天板５０は、コンロ本体２０のフランジ２２より外側に延出する天板５０の周縁部の下面にパッキン５４を固着して、該パッキン５４を介してワークトップ２の上面に着地される。図１４（ａ）において符号１７は点火プラグである。
【００４９】
フード６０は、通気口６３の前縁部から後方に向けて上方に傾斜した傾斜部６０ａと前端部６０ｂと後端部６０ｄと両側壁部６０ｃとからなるアルミニウム製のフードに形成している。フード６０は前端部６０ｂの係止部としての段部６０ｂ１を天板５０の通気口６３の前縁６３ａに係止し、両側壁６０ｃの係止部としての段部６０ｅを通気口６３の後縁６３ｂに係止して通気口６３に設置される。
【００５０】
なお、図１４（ｂ）に示すように、前端部、後端部に係止部６０ｅ１、６０ｅ２を有する脚部６０ｃ１を両側壁部６０ｃに設ければ、フード６０の傾斜角度を保つと共にフード６０を通気口６３の口縁に係止することができる。
【００５１】
本実施の形態の天板５０でも、天板の後部に通気口６３を設けるので、通気口６３を大面積に設けることができる。さらに通気口６３にフード６０（特に後方に向けて上昇する向きに傾斜させたフード）を設けたので、バーナ５１（５１ａ、５１）でのガス燃焼時の後壁面４に向かう空気の流れに影響されずに、空気を通気口６３から吸い込んで、大面積の通気口から十分な空気をコンロ本体２０内に供給することができ、良好な燃焼を実現できる。また通気口６３およびそれを覆うフード６０は天板５０の後部にあるので、コンロ１０を前方から見たときの見栄えが損なわれることがない。
【００５２】
図１５は、本発明の第５の実施形態を示す断面図で、本実施形態では、フード６５の前部両側端に折曲して支持部６５ａを形成し、金属板としてのアルミニウム板からなる天板５０の通気口６３の前側端面に取り付けられたＬ字状の各支持板５５に設けた軸５５ａを支持部６５ａの孔に挿入する構成の角度可変装置を設けたことにより、フード６５を傾き角度調節可能とした。
【００５３】
第５の実施形態によれば、第２の実施の形態と同様に空気の流れに応じてフード６５の角度を調節することにより、十分な空気の吸入を行わせることができる。
【００５４】
本発明の第６の実施形態は、図１６（ａ）及び図１６（ｂ）に示すように、金属板としてのアルミ板からなる天板５０の後端縁から所定距離を存した位置に該金属板の後端縁に沿って延びる切れ目を設け、該切れ目を介して前方側を折り起こした折り起こし片により形成されたフード６６と通気口６３とを備えている。即ち、天板５０に長方形の前側の長辺を除く３辺に切り込み５６ａ（切れ目）を設けて、該３辺の切り込み５６ａで囲まれた長方形の片５６ｂを傾斜姿勢に起こして、通気口６３を形成すると共に折り起こした長方形の片５６ｂ（折り起こし片）をフード６６とした。なお、片５６ｂは起立させて立壁としてもよいが、図示するように傾斜させることで異物の落入を防止する効果が得られる。これによって、天板５０の加工によってのみフード６６を形成することができ、部品点数を削減することができる。
【００５５】
なお、上記例では３辺に切り込みを設けてフード６６を切り起こして形成したが、この変形例として、図１６（ｃ）に示すように、天板５０の後部側に１辺の切り込みを設けて、フード６６と通気口６３とを切り絞り起こしにより成形することもできる。
【００５６】
また、第６の実施形態においては、図１６（ｂ）に示すように、フード６６を介して連結部材２０ｄ１によって天板５０とコンロ本体２０とを連結することができる。このとき、フード６６の下面側にＬ字状に折り曲げた金属板による連結部６６ａをスポット溶接等の手段により固設しておき、ここに連結部材２０ｄ１の上端連結部２０ｄ２をねじｎによって連結する。
【００５７】
また、これ以外に、図１７（ａ）及び図１７（ｂ）に示すように、フード６６の後端縁を下方に折り曲げて連結部６６ｂを形成し、該連結部６６ｂの所定位置にねじ穴６６ｃを設け、該連結部６６ｂに連結部材２０ｅ１の上端連結部２０ｅ２をねじ止めしてもよい。
【００５８】
また、連結部材２０ｅ１を用いない場合には、図１８（ａ）及び図１８（ｂ）に示すように、コンロ本体２０のフランジ２２の一部を切り起こして被連結部２２ｃを形成し、ここにフード６６の後端縁の連結部６６ｂをねじ止めしてもよい。
【００５９】
これまでの図１乃至図１６を参照して説明したドロップインコンロ１０では、いずれも、天板３０、５０の後部に通気口３３、６３を長穴状に設けたが、通気口は天板の後縁を残すことなく、天板後縁を長方形状に切り欠いた開口でもよい。
【００６０】
図１９乃至図２０に示す第７の実施形態では、金属板としてのアルミ板からなる天板５０の後辺を全幅にわたり折り起こして、天板後部に後部側が上昇する傾斜状態のフード６８を形成し、フード６８の下方にコンロ本体２０のフランジ２２との間に通気口６３Ａが形成される。この場合は、天板５０の後部では天板がワークトップ２の上面に接触しないので、コンロ本体２０のフランジ２２とワークトップ２との間には全周にわたって本体パッキン５８を介挿する。そして天板５０のフード６８以外の部分とワークトップ２との間に介挿するトッププレートパッキン５４は、本体パッキン５８を入れた分だけ厚くする。
【００６１】
また天板の後縁を折り起こして、コンロ本体２０のフランジ２２との間に通気口６３Ａを形成する他の例を図１９（ｃ）に示す。この例では、天板５０Ａの後縁の両側部５０Ｂを残して中間部を折り起こしてフード７０を形成した。
【００６２】
また、第７の実施形態においては、図１９（ｂ）に示すように、フード６８を介して連結部材２０ｆ１によって天板５０とコンロ本体２０とを連結することができる。即ち、フード６８の下面側にＬ字状に折り曲げた金属板による連結部６８ｂをスポット溶接等の手段により固設しておき、ここに連結部材２０ｆ１の上端連結部２０ｆ２をねじｎによって連結する。
【００６３】
また、これ以外に、図２１（ａ）及び図２１（ｂ）に示すように、フード６８の後端縁を下方に折り曲げ、更に一部を更に下方に延出させるようにして連結部６８ａを形成し、該連結部６８ａにねじ穴６８ｂを設け、該連結部６８ａに連結部材２０ｇ１の上部連結部２０ｇ２をねじ止めしてもよい。
【００６４】
また、連結部材２０ｇ１を用いない場合には、図１８（ａ）に示すように、コンロ本体２０のフランジ２２の一部を起立させて被連結部２２ｃを形成し、ここにフード６８の後端縁の連結部６８ａをねじ止めしてもよい。
【００６５】
なお、第６及び第７の実施形態において、天板５０の後縁を折り起こすとき、例えば図２２（ａ）に示すように、折り起こす部分、即ちフード６８が形成される部分を他部より肉薄に形成しておくことで、天板５０の曲げ加工が容易に行なえる。また、例えば図２２（ｂ）に示すように、天板５０を折り起こす際の折り曲げ位置に沿って折り溝６８ｃを形成しておくことによっても、天板５０の曲げ加工が容易に行なえる。
【００６６】
以上の第４〜第７の実施形態では、いずれも、外炎式のガスバーナ５１を備えたドロップインコンロについて説明したが、ガスバーナは内炎式であってもよい。なお、金属板として他の金属、例えばＳＵＳ板とすることができる。しかし、アルミ板は軽いので、板厚数ｍｍの板の天板とすることによって、ガラスと同様重量感のある天板とすることができる。
【００６７】
また、各実施形態において説明した天板とコンロ本体との連結構造はそれぞれの実施形態においてのみ採用されるものではなく、天板の寸法やコンロ本体の寸法の応じて何れの連結構造を選択してもよい。
【００６８】
また、この種のコンロには、図２３に示すように、コンロ本体２０の前面２０ｚがワークトップ２の下方で使用者側に露出し、この露出した前面２０ｚにコンロ本体２０に内装されたグリル庫６７の前面開口６７ｚが形成されると共に、この前面開口６７ｚをグリル扉６８が開閉するようになっているものがある。なお、天板３０は第３の実施形態の図８に示す天板３０と同じものである。
【００６９】
このように、コンロ本体２０の内部にグリル庫６７を備えたものにおいては、通気口３３を排気口とすることができる。即ち、グリル庫６７を備えることにより、前面側（前面開口６７ｚ等）からの燃焼用一次空気の取り入れが行なえるので、グリル庫６７からの排気を通気口３３を介して外部に排出することができる。このとき、通気口３３の上部が、仕切枠材４５に一体に設けられて垂直壁４５ａの上端から後方に向けて上方に湾曲して傾斜しているフード４５ｃにより覆われるので、通気口３３からコンロ本体２０の内部に異物が落入することが防止できる。なお、図２３においては天板３０をコンロ本体２０に連結する手段を図示しないが、先に示した天板の連結手段を採用することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a drop-in stove that is suspended and installed in an opening provided in a worktop such as a system kitchen.
[0002]
[Prior art]
Conventionally, a system kitchen in which a drop-in stove is installed on a worktop of a cooking table is known. In this drop-in stove, the top surface of the stove body containing the gas burner is covered with a top plate having an opening facing the gas burner, and the flange at the upper end of the peripheral wall of the stove body is locked to the top surface of the work top. It is suspended in the top opening.
[0003]
Even in such a drop-in stove, if the front surface of the stove body is exposed to the user side below the worktop, an operation part can be provided on the front surface, and a vent can be formed on the front surface. Air and cooling air can be taken in.
[0004]
However, in the case where the front surface of the stove body is not exposed to the user side below the work top and the operation portion is provided on the top plate, the vent hole cannot be provided in the vicinity of the operation portion. Moreover, in order to prevent the heat in the stove body from reaching the outside as much as possible, the stove body has improved its sealing performance. For this reason, the combustion primary air cannot be taken in from the periphery of the stove body.
[0005]
Therefore, as can be seen in Patent Document 1 below, a drop-in stove is known in which an opening is provided in a falling wall around the top plate and this is used as a vent. According to Patent Document 1, it is possible to take combustion air into a stove body through a vent even in a stove body having high sealing performance. However, in this case, in order to secure sufficient combustion air, it is necessary to increase the falling wall around the top plate to secure a sufficient opening area, but the top plate is thinned to improve the design. In such a case, the falling wall of the top plate has to be made small, and even if a vent hole is provided there, there is a disadvantage that it is difficult to ensure a sufficient amount of ventilation.
[0007]

[0008]
[Problems to be solved by the invention]
By eliminating such inconvenience, the present invention can secure sufficient combustion air.WhenBoth aims to provide a drop-in stove with an excellent appearance.
[0009]
[Means for Solving the Problems]
  In order to achieve such an object, the present invention comprises a stove body that contains a gas burner and has an opening on the upper surface thereof, and a top plate that covers the upper surface opening of the stove body. In the drop-in stove to be hung, a vent hole to the inside of the stove body is provided at the rear part of the top plate, and the vent holeFrom the leading edgeA hood is installed to block the airflow that flows immediately above the vent.The vent is provided upward with respect to the top surface of the top plate, and the hood is formed at an inclined portion that is inclined upward from the front edge of the vent to the rear, and a front end portion of the inclined portion. A vertical wall that closes the front edge of the vent, an air intake portion that opens below the rear end of the inclined portion and continues to the vent, and a pair of side walls formed on both side ends of the inclined portion. It is provided as a unit, and is detachably provided in the vent of the top plate.It is characterized by that.
[0010]
  In the present invention, since the vent is provided not on the hanging wall around the top plate but on the top surface of the top plate, the vent can be provided with a large area. However, in most cases, the drop-in stove is installed in front of the kitchen wall, and the flow of wind along the rear wall is generated by burning the burner. In this state, it is difficult to take in the combustion air from the air vent by being obstructed by the air flow that flows immediately above the air vent. Therefore, in the present invention,To ventA hood is provided to block the flow of air that flows immediately above the vent, so even if there is a wind flow that flows backward from the front of the stove to the vent, air can be sucked from the vent. Since sufficient air can be supplied into the stove body, good combustion can be realized. Moreover, since the vent and the hood that covers it are located at the rear of the top plate, the appearance when the stove is viewed from the front is not impaired.
  The hood includes an inclined portion inclined upward from the front edge of the vent to the rear, a vertical wall formed at a front end portion of the inclined portion and closing the front edge of the vent, and a rear portion of the inclined portion. An air intake portion that opens below the end portion and continues to the vent and a pair of side walls formed on both side ends of the inclined portion are integrally provided.Above the ventThecoverSoIt is also good in terms of wind shielding effect and preventing foreign matter from falling into the vent.And the hood has an inclined partFrom the front edge of the vent to the rearBecause the shape is inclined upwardThe shape does not have to be large.
[0011]
  The present invention also provides:In the rear part of the top plate, there is provided a vent to the inside of the stove main body, a hood for blocking the airflow flowing immediately above the vent from the front edge side of the vent is provided, and the hood is inclined upward And an angle varying device capable of changing the inclination angle of the hood.Depending on the distance between the stove and the rear wall, the air flow will be different, and the air intake state from the vents will be different, making it impossible to inhale sufficient air. For example, sufficient air can be inhaled by adjusting the angle of the hood according to the distance from the rear wall surface.
[0012]
  According to the present invention, the top plate can be a metal plate, for example, an aluminum plate having a thickness of several millimeters, and an opening can be provided in the rear part of the metal plate to make the vent..
[0013]
  In the present invention, when the top plate is a metal plate, a slit extending along the rear edge of the metal plate is provided at a position at a predetermined distance from the rear edge of the metal plate. The folded piece that is folded forward is used as the hood. Thereby, the said vent and the said food | hood can be simultaneously formed in this metal plate. In this case, specifically, a cut on three sides except for the front side of the square is formed on the rear side of the top plate, and a part of the top plate is folded through the cut. Alternatively, it may be folded while forming a cut on one side on the rear side of the top plate.
  Further, the hood may be formed at the rear portion of the top plate by the folded piece at the rear edge of the top plate, and the vent portion may be formed by opening the rear portion of the stove body located below the hood. That is, when the top plate is a metal plate, the rear edge of the top plate is separated from the stove body by folding up the rear side of the metal plate over the entire width, thereby forming a vent into the stove body. A hood that blocks airflow that flows from the front edge side of the vent to the position immediately above the vent can be formed by the folded piece formed by folding.
[0014]
  In the present invention, when the top plate is a thick metal plate, the hood is preferably formed thinner than other portions. Thereby, processing, such as folding of the said hood, can be made very easy. Further, a folding groove may be provided along the folding position of the metal plate when the hood is folded. Also by this, processing such as folding of the hood can be made extremely easy.
[0015]
  Further, in the present invention, it is preferable to connect the connecting portion that is suspended from the rear end edge of the hood to the connected portion that rises in the vent from the rear portion of the stove body, and further, the connected portion Is preferably formed by cutting and raising a part of the flange provided on the periphery of the stove body. By doing so, the top plate can be firmly connected to the stove body. And since the connecting member and the connecting part are hidden behind the hood and can not be seen from the front position of the stove, the top plate and the stove main body can be connected while keeping the appearance of the top plate good. it can.
[0016]
  In the present invention,The top plate may be constituted by a plate body and a metal frame-like frame body. In this case, it is preferable that the frame body includes a partition frame material that defines an installation portion for installing the plate body and the vent hole, and the hood is integrally formed on the partition frame material. Accordingly, the ventilation holes and the hood can be provided in the frame body, and a bending process or the like on the plate body is not necessary. Therefore, for example, a glass plate body or a thick metal plate can be easily employed. AndA connecting member for connecting the stove body and the frame is provided, a lower end portion of the connecting member is connected to a rear side of the stove body, and an upper end portion is connected to the frame body below or behind the hood. Is preferred. By doing so, the upper end portion of the connecting member is hidden under and behind the hood, so that it cannot be seen from the front position of the stove, and the top plate and the stove body can be connected while maintaining the appearance of the top plate well. it can.
[0017]
In the present invention, the connecting portion may be suspended from the rear edge of the hood. The connecting portion can be employed when either the hood is formed by folding the rear edge of the top plate or when the hood is formed on a part of the frame.
[0018]
  Moreover, it is preferable that the said food | hood is made into the inclined shape which raises toward back. Thereby, the upper part of a vent hole can be covered with a hood, and the effect of preventing wind and foreign matter from falling into the vent hole is good, and the shape does not have to be large.
[0019]

In the present embodiment, the front end portion 40b of the hood 40 is formed on the vertical wall, contacts the rear surface of the vertical wall 38a of the partition frame member 38, and the front edge portion 33a of the vent 33 is closed by the front end portion 40b of the hood 40. 40 under the rear end portion 40d is an air intake portion that opens to the vent 33. The rear end portion 40d of the hood 40 is horizontally bent outward, and the long hood 40 is reinforced with the front end portion 40b.
[0031]
Side walls 40c are formed at both ends of the inclined portion 40a, and the horizontal edges 37b of the left and right frame members 37 function as seating portions at the lower ends of the side walls 40c, so that the hood 40 can be detached from the vent 33. Arranged. As shown in FIG. 3, if the rear edge 38 c is protruded slightly longer than the plate thickness of the hood 40 behind the vertical wall 38 a of the partition frame member 38, it functions as a seating portion for the front end 40 b of the hood 40. In addition, the hood 40 can be disposed in the vent 33 more stably. In the hood 40, the inclined portion 40a, the front end portion 40b, and both side walls 40c are integrally formed by bending an aluminum plate.
[0032]
The inclination of the inclined portion 40a of the hood 40 may be such that a sufficient distance can be provided between the rear end portion 40d of the hood 40 serving as an air suction portion of the hood 40 and the upper end of the rear frame member 36. Generally, about 20 to 60 degrees is preferable. If the tilt angle is too small, the air suction portions cannot be sufficiently spaced, and if the tilt angle is too large, the appearance will deteriorate. In this example, the inclination angle of the inclined portion 40a is set to 25 degrees, and the interval between the upper end of the vertical wall 36a and the rear end portion 40d of the rear frame member 36 is secured to 14 mm.
[0033]
In FIG. 3, when the gas is burned in the burner 11, the air flow on the upper surface of the drop-in stove 10 faces rearward on the vent 33 from the front portion of the stove because of the upward flow caused by the rear wall surface 4. For this reason, even if the vent hole 33 is simply provided at the rear part of the top plate 30, it is obstructed by the flow of air flowing from the front of the stove to the most recent position on the vent hole 33, and from the periphery of the vent hole 33 toward the vent hole 3. Thus, it is difficult for air to enter, and it becomes difficult to suck the primary air for combustion into the stove body 20.
[0034]
On the other hand, if the hood 40 is provided in the vent 33, the flow of air flowing backward from the front of the stove to the immediate vicinity on the vent 33 is shielded by the front of the hood 40 or warped upward. On the back surface of the hood 40, there is no air flow flowing toward the rear wall surface 4 immediately above the vent hole 33. Therefore, since air is sucked from the vent 33 without being affected by the air flow toward the rear wall 4, sufficient air can be supplied from the large vent 33 into the stove body 20. Combustion can be performed. The form of the hood 40 may be provided on the front edge of the vent 33 in the form of a standing wall. In particular, the hood 40 may be provided with a cover portion that covers the vent hole 33, or from the front edge that also serves as the cover portion. If it inclines so that it may raise toward back, it is good also on the wind-shielding effect and the fall prevention effect to the ventilation hole of a foreign material.
[0035]
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is an explanatory cross-sectional view showing the main part of the second embodiment.
[0036]
Depending on the distance between the drop-in stove 10 and the rear wall surface 4, the air flow differs, and as a result, the intake state of air from the vent 33 may be different and sufficient air cannot be inhaled. Therefore, in this embodiment, the inclination angle of the hood 42 can be adjusted. The hood 42 is made of an aluminum plate, and an angle variable device for the hood 42 is formed by pivotally supporting a support portion 42b formed on both sides of the front portion of the hood 42 on a shaft 42a provided on the left and right frame members 37.

[0041]
Further, in the third embodiment, the rear frame member 36 is in a position where it cannot be seen from the front by the hood 45c, so that the upper connecting portion 20b2 of the connecting member 20b1 is attached to the rear frame member 36 as shown in FIG. You may make it connect with the screw n. In addition, as shown in FIG. 11, a connecting plate 36f is provided on the horizontal edge 36b of the rear frame member 36, and the upper connecting portion 20c2 of the connecting member 20c1 is connected to the connecting plate 36f with a screw n. May be. The screwing portion 36g of the connecting plate 36f is formed to be inclined toward the opening direction on the rear side of the hood 45c, and the upper connecting portion 20c2 of the connecting member 20c1 corresponds to the screwing portion 36g of the connecting plate 36f. It is formed in a shape that comes into contact with the back surface of the lever. As a result, the connecting portion between the upper connecting portion 20c2 of the connecting member 20c1 and the screwing portion 36g of the connecting plate 36f is hidden by the hood 45c and cannot be seen from the front of the stove 10, and the appearance of the top plate is not impaired. In addition, since the screw n can be screwed from the rear of the hood 45c, the connecting operation under the hood 45c can be easily performed without the hood 45c getting in the way.
[0042]
In this example, the rear frame member 36 and the left and right frame members 37 are fixed by riveting an L-shaped metal fitting 47 between the horizontal edge portions 36b and 37b. Similarly to the form, it may be assembled by caulking due to the unevenness of these tip portions.
