Description

【０００１】
【発明の属する技術分野】
本発明は燃焼制御等の制御回路を備えた組込型加熱調理器に関するものである。
【０００２】
【従来の技術】
従来この種の組込型加熱調理器では図８に示すように本体６を上下に仕切る仕切板１３を設け、上部にコンロ４を備え、下部に制御回路７を位置させて、制御回路へのコンロの煮こぼれや水滴の侵入を防止していた。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来の構成ではグリル５を使用した際、グリルの輻射熱により本体６内部の温度が上昇して制御回路が高温になり、防熱板を何枚も設けて断熱しなければならないという課題や、制御回路７を交換する際に上部のコンロ４や仕切板１３を取り外さなければ交換できないという課題を有していた。
【０００４】
【課題を解決するための手段】
本発明は上記課題を解決するために、本体の後方で、かつ前記トッププレートの排気口が上方に位置する部分に制御回路を取り付けた制御回路取付板を垂直に設け、前記制御回路をカバーで覆う構成とし、前記制御回路取付板を略逆Ｌ字状に構成し、制御回路冷却用の穴を制御回路下方の前記制御回路取付板の底面に設けると共に、前記制御回路取付板の底面とその下方の後板との間に空間Ａを設けたものである。
【０００５】
上記発明によれば、制御回路の温度上昇の低減と制御回路の交換の際に他の部品を取り外さなくても交換が可能となる。さらに、制御回路取付板の底面と後板の空間Ａから冷却空気を取り入れ、前記制御回路取付板の底面に設けた制御回路冷却用の穴を通して上方の制御回路へ冷却空気を供給することによって断熱だけでなく、より積極的にカバー内の制御回路の温度上昇の低減を図ることができる。
【０００６】
【発明の実施の形態】
本発明はキッチンカウンターの開口部にコンロとグリルを備えた本体を設けると共に、その上部に、排気口を後方に有するトッププレートを配置し、本体の後方で、かつ前記トッププレートの排気口が位置する部分に制御回路を取付けた制御回路取付板を略垂直に設け、前記制御回路の正面、上面及び側面をカバーで覆ったものである。
【０００７】
そして、制御回路をカバーで覆うことによりコンロの煮こぼれやトッププレートの清掃時の水こぼしによる水の侵入を防止すると共に、制御回路を本体の後方に位置させることにより、制御回路の交換時に前記仕切板等を外さなくても交換ができる。また、グリルを使用した際でもグリルの輻射熱を受けにくく温度の低い本体の後方に制御回路を位置させたため、防熱板を何枚も設けて断熱する必要がなくなり、前記カバーだけで水の侵入防止と断熱の効果が得られる。
【０００８】
さらに、制御回路取付板を略」形に構成し、制御回路冷却用の穴を制御回路下方の前記制御回路取付板の底面に設けると共に、前記制御回路取付板の底面とその下方の後板との間に空間Ａを設けたものである。
【０００９】
そして、制御回路取付板の底面と後板の空間Ａから冷却空気を取り入れ、前記制御回路取付板の底面に設けた制御回路冷却用の穴を通して上方の制御回路へ冷却空気を供給することによって断熱だけでなく、より積極的にカバー内の制御回路の温度上昇の低減を図ることができる。
【００１０】
また、制御回路取付板の底面に、下方に向けて曲げ片あるいは凸状の突起を設けて、下方の後板との間に空間Ａを設けたものである。
【００１１】
そして、このような構成をとることによっても断熱だけでなく、より積極的にカバー内の制御回路の温度上昇の低減を図ることができる。
【００１２】
また、キッチンカウンターの開口部にコンロとグリルを備えた本体を設けると共に、その上部に、排気口を有するトッププレートを配置し、前記本体の後方で、かつ前記トッププレートの排気口が位置する部分に制御回路を取付けた制御回路取付板を略垂直に設け、前記制御回路の正面、上面及び側面をカバーで覆い、前記制御回路取付板を略逆Ｌ字状に構成し、制御回路冷却用の穴を制御回路下方の前記制御回路取付板の底面に設けると共に、前記制御回路取付板の底面に設けた制御回路冷却用の穴と連通して下方の後板に穴を設けたものである。
【００１３】
そして、このように制御回路冷却用の穴と連通して後板に穴を設けることによって本体外部の低温な冷却空気をカバー内へ供給することができ、より制御回路の冷却が促進される。
【００１４】
また、カバーの上面を制御回路取付板より高くして、上部に空間Ｂを設けたものである。
【００１５】
そして、上部に空間Ｂを設けることによって冷却空気は、カバー内を下から上へと制御回路を冷却しながら移動してカバー内の空気の対流がよりスムーズになり、カバー内の温度低減がさらに促進される。
【００１６】
さらに、カバーの上面を制御回路取付板より後方に伸ばすと共に下方に折り曲げて、制御回路取付板の後部に空間Ｃを設けたものである。
【００１７】
そして、カバー上面を制御回路取付板よりも後方に伸ばして折り曲げることにより、トッププレートの排気口から侵入した水のカバー内への侵入を防止すると共に、制御回路取付板の後部に空間Ｃを設けているため、カバー内の冷却空気は円滑に前記空間より排出されてカバー内の制御回路の温度低減が図れる。
【００１８】
また、制御回路取付板とカバーを係止させたものである。
そして、このように係止させることによって、カバーの前方への動きを防止して、本機器の荷扱い時落下した場合に、前記カバーが移動して制御回路が露出して水が浸入するといった現象を防止することができる。
【００１９】
以下、本発明の実施例について図面を参照して説明する。
（実施例１）
図１は、本発明の実施例１の組込型加熱調理器の縦断面図である。
【００２０】
図１において、キッチンカウンターの開口部１の上面に排気口２を有するトッププレート３を載置する。キッチンカウンターの開口部１からコンロ４、グリル５を備えた本体６を載下し、その本体６を上下に仕切る仕切板１３の後方に制御回路７を取り付けた制御回路取付板８を略垂直に設ける。そして、その制御回路７の正面、上面及び側面を覆うカバー１２を設ける。
【００２１】
次に作用を説明する。コンロ４の煮こぼれや清掃時の水がトッププレート３の排気口から本体６の内部へ侵入しても、カバー１２で制御回路７を覆っているため制御回路７への水の侵入を防止できると共に、制御回路７の交換に際してもコンロ４や仕切板１３を取り外さなくても交換ができる。さらに、グリル５使用時の輻射熱による温度上昇に対して制御回路７は、輻射熱を受けにくく温度の低い本体６の後方に位置させているため、制御回路７をカバー１２一枚だけで断熱することができる。
【００２２】
（実施例２）
図２は、本発明の実施例２の組込型加熱調理器の要部の縦断面図である。
【００２３】

【００２４】
次に作用を説明する。底面１４と後板１７の空間Ａ１８から冷却空気を取り入れ、底面１４に設けた制御回路冷却用の孔１５を通して上方の制御回路７へ冷却空気を供給することによって断熱だけでなく、より積極的に制御回路７の温度上昇の低減を図ることができる。

【００２９】
図４において、底面１４に設けた制御回路冷却用の孔１５と連通して、後板１７に穴２０をあけている。
【００３０】
その作用は、穴２０と制御回路冷却用の穴１５を通して、本体外部の低温な冷却空気を制御回路７へ供給することができて制御回路７の冷却が促進されることである。
【００３１】
（実施例５）

【００３２】
図５において、カバー１２の上面２１を制御回路取付板８より高くして、上部に空間Ｂ２２を設けている。
【００３３】
次に作用を説明する。制御回路冷却用の穴１５を通してカバー１２内へ侵入した冷却空気はカバー１２内を下から上へと制御回路７を冷却しながら移動して空間Ｂ２２から排出される。このことによって、カバー１２内の空気の対流が促進され、さらに制御回路の冷却が促進される。
【００３４】
（実施例６）
図６は、本発明の実施例６の組込型加熱調理器の要部の縦断面図である。
【００３５】
図６において、カバー１２の上面２１を制御回路取付板８より後方に伸ばすと共に下方に折り曲げて空間Ｃ２３を設けている。
【００３６】
その作用は、トッププレートの排気口から侵入した水がカバー１２の上面へ滴下しても上面を後方へ伸ばすと共に下方に折り曲げていることによって、水切り効果が得られ、表面張力を有する水滴が制御回路取付板８へと伝い制御回路７へ侵入するといった現象を防止することができることである。さらに、空間Ｃ２３を設けているためカバー１２内の冷却空気は円滑に排出されて、制御回路７の冷却を行うことができることである。
【００３７】
（実施例７）
図７は、本発明の組込型加熱調理器の要部の横断面図である。
【００３８】
図７において、制御回路取付板８にカバー１２の係止片２４を係止すると共に左側面のフランジをビス２５で後板１７に固定している。
【００３９】
次に作用を説明する。このように係止させることによってカバー１２の前方への動きを防止して、本機器の荷扱い時に落下した場合であってもカバー１２が前方へ移動して制御回路７が露出しトッププレートの排気口から侵入した水が制御回路を浸すといった不安全な現象を防止することができる。
【００４０】
【発明の効果】
以上の説明から明らかなように本発明の組込型加熱調理器によれば、次の効果が得られる。
【００４１】
制御回路をカバーで覆うことによりコンロの煮こぼれやトッププレートの清掃時の水こぼしによる水の侵入を防止すると共に、制御回路を本体の後方に位置させることにより、制御回路の交換時に仕切板等を外さなくても交換ができる。さらに、グリルを使用した際でもグリルの輻射熱を受けにくい低温な本体後方に制御回路を位置させたため、防熱板を何枚も設けて断熱する必要がなくなり、カバーだけで水の侵入防止と断熱の効果が得られる。
【００４２】
また、制御回路取付板の底面と後板の空間Ａから冷却空気を取り入れ、制御回路取付板の底面に設けた制御回路冷却用の穴を通して上方の制御回路へ冷却空気を供給することによって、断熱だけでなく、より積極的にカバー内の制御回路の温度上昇の低減を図ることができる。
【００４３】
また、制御回路冷却用の穴と連通して後板に穴を設けることによって本体外部の低温な冷却空気をカバー内へ供給することができ、より制御回路の冷却が促進できる。
【００４４】
また、制御回路取付板の上部に空間Ｂを設けることによって冷却空気は、カバー内を下から上へと制御回路を冷却しながら移動して前記空間Ｂから排出されるのでカバー内の温度低減をさらに促進できる。
【００４５】
また、カバー上面を制御回路取付板よりも後方に伸ばして折り曲げることにより、トッププレートの排気口から侵入した水のカバー内への侵入を水切り効果によって防止すると共に、制御回路取付板の後部に空間Ｃを設けているため、カバー内の冷却空気は円滑に前記空間Ｃから排出されてカバー内の制御回路の温度低減が図れる。
【００４６】
また、制御回路取付板とカバーを係止させることによって、カバーの前方への動きを防止してカバーの動きによる制御回路の露出、さらに浸水といった不安全な現象を防止できる。
