Description

【０００１】
【発明の属する技術分野】
本発明は、家庭用の電動調理機の本体と調理容器の着脱の構成に関するものである。
【０００２】
【従来の技術】
従来の電動調理機は、例えば図７に示すように、電動機１を内蔵し調理容器取り付け部２を備えた本体３の上に調理容器４を台座５の部分により着脱自在に装着し駆動コネクタ６と従動コネクタ７を介して調理ツール８を回転させて食材を調理していた。調理容器４の台座５の側面には複数個の長円形の突起部９を配置し、調理容器取り付け部２の側面には突起部９に対応した複数個のＬ字形状のフック部１０を配置して調理容器４を本体３の台座５の部分に突起部９とフック部１０によりバイヨネット嵌合させていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、前記のような構成によると調理容器５を回転させて取り外すときに突起部９がフック部１０の側面に当接したところで一端動作が中断しその後に調理容器５を上に持ち上げるという２段階動作になっており取り外しにくいという課題を有していた。
【０００４】
本発明は、前記従来の課題を解決するもので、着脱がしやすいバイヨネット嵌合の調理容器を備えた電動調理機を提供することを目的とする。
【０００５】
【課題を解決するための手段】
前記従来の課題を解決するために本発明の電動調理機は、電動機を内蔵し調理容器取り付け部を備えた本体と、前記調理容器取り付け部に着脱自在に嵌合し前記電動機により回転駆動される調理ツールを備えた調理容器を有し、前記調理容器の台座と前記調理容器取り付け部のいずれか一方の側面に複数個の突起部を配置し、他方の側面に前記突起部に対応した複数個のフック部を配置して前記調理容器を前記本体にバイヨネット嵌合させる電動調理機において、前記フック部の反開口側背面を傾斜面とすると共に、前記突起部の反嵌合側背面を前記傾斜面と同方向の傾斜面としたものである。
【０００６】
これにより、調理容器を回転させて取り外すときに突起部がフック部の反開口側背面に当接してもここが傾斜面になっていることから動作が中断することなく調理容器は回転しながら上に持ち上がっていくため取り外しやすくすることができる。
【０００７】
【発明の実施の形態】
本発明の請求項１に記載の発明は、電動機を内蔵し調理容器取り付け部を備えた本体と、前記調理容器取り付け部に着脱自在に嵌合し前記電動機により回転駆動される調理ツールを備えた調理容器を有し、前記調理容器の台座と前記調理容器取り付け部のいずれか一方の側面に複数個の突起部を配置し、他方の側面に前記突起部に対応した複数個のフック部を配置して前記調理容器を前記本体にバイヨネット嵌合させる電動調理機において、前記フック部の反開口側背面を傾斜面とすると共に、前記突起部の反嵌合側背面を前記傾斜面と同方向の傾斜面としたものであり、調理容器を回転させて取り外すときに突起部がフック部の反開口側背面に当接してもここが傾斜面になっていることから動作が中断することなく調理容器は回転しながら上に持ち上がっていくため取り外しやすくすることができる。
【０００８】
そして、調理容器を回転させて取り外す場合に、突起部がフック部の反開口側背面の傾斜面に当接したとき突起部の反嵌合側背面も同方向の傾斜面となっているため接触面を大きくでき突起部の強度を増すことができる。
【０００９】
本発明の請求項２に記載の発明は、請求項１の構成において、フック部の開口外部面を傾斜面とすると共に、突起部の嵌合側面を前記フック部の開口外部面の傾斜面と同方向の傾斜面としたものである。
【００１０】
そして、フック部の反開口側背面と開口外部面の両方をを傾斜面とすることにより、フック部の反開口側背面だけを同じ傾斜角度の傾斜面とした場合に対してフック部の全高を低くコンパクトにすることができる。
【００１１】
また、調理容器を本体の調理容器取り付け部の任意の位置に入れたときも、調理容器はフック部の反開口側背面だけを傾斜面とした場合に対してより少ない回転角度で係止できる位置に、フック部の反開口側背面または開口外部面に沿って移動することができる。
【００１２】
そして、調理容器を本体の調理容器取り付け部に入れた場合に、突起部がフック部の開口外部面の傾斜面に当接したとき突起部の嵌合側面も同方向の傾斜面となっているため接触面を大きくでき突起部の強度を増すことができる。
【００１３】
本発明の請求項３に記載の発明は、請求項１又は２の構成において、調理ツールは一方向に回転し、調理容器は台座に前記調理ツールの回転方向と同方向にねじ込んで着脱自在に取り付け、前記台座は本体上の調理容器取り付け部にバイヨネット嵌合で前記調理ツールの回転方向と同方向に回して取り付けるようにしたものである。
【００１４】
そして、調理容器と台座をねじ込み式で分離可能にし調理ツールの洗浄を容易にした構成で、調理容器を回転させて取り外すときに突起部がフック部の反開口側背面に当接してもここが傾斜面になっていることから衝撃が小さいため、調理容器と台座のねじが緩みにくくなり調理物が漏れにくくなる。
【００１５】
また、調理容器を回転させて取り外すときに突起部がフック部の反開口側背面に当接してもここが傾斜面になっていることから動作が中断することなく調理容器は回転しながら上に持ち上がっていくため取り外しやすい。
【００１６】
本発明の請求項４に記載の発明は、請求項１〜３のいずれかの構成において、フック部の開口外部面とこれに隣接する他のフック部の反開口側背面との間隔を突起部の横幅の２倍以上としたものである。
【００１７】
そして、調理容器と台座をねじ込み式で分離可能にした構成で、調理容器を回転させて取り外すときに突起部がフック部の反開口側背面に当接するまでの距離が長くなり、当接したときの衝撃をさらに小さくできるため、調理容器と台座のねじがより緩みにくくなり調理物が漏れにくくなる。
【００１８】
