【発明の属する技術分野】
本発明は、衣類などの洗濯を行う洗濯機に関するものである。
【０００２】
【従来の技術】
従来、この種の洗濯機は図６および図７に示すような構成が一般的であった。以下、その構成について説明する。
【０００３】
図６に示すように、洗濯機本体１は、上部に上部枠体２を設け、この上部枠体２には衣類投入時に開閉する蓋３を後方で軸支している。安全スイッチ４は上部枠体２の内部に装着し、少なくとも蓋２の閉開に応じてオン、オフするもので、蓋３の後辺壁に軸５と連結したてこ壁を有するスイッチ操作部６を設け、一方、安全スイッチ４に蓋開閉検知レバー７を設け、蓋３を閉じると、スイッチ操作部６によって蓋開閉検知レバー７をすくい上げるように配置し、スイッチ操作部６により安全スイッチ４をオン、オフして、脱水の動作をオン、オフさせるよう構成している。
【０００４】
上記構成において動作を説明すると、図６に示すように、蓋３が閉じたときにはスイッチ操作部６により安全スイッチ４の蓋開閉検知レバー７が押し上げられているが、図７に示すように、蓋３を徐々に開くと、スイッチ操作部６が徐々に下がるため、開閉検知レバー７も徐々に下がる。所定の位置まで蓋開閉検知レバー７が下がると安全スイッチ４がオフとなり、脱水の動作が止まる構造となっている。
【０００５】
さらに、安全スイッチ４は下方に水受け槽８内に回転自在に設けた脱水槽９の異常振動を検知する異常振動検知レバー１０を備えており、製品の移動や転倒などを事前に検知し、脱水動作を止める検知機能を有している。
【０００６】
【発明が解決しようとする課題】
このような従来の構成では、安全スイッチ４は下方に水受け槽８内に回転自在に設けた脱水槽９の異常振動を異常振動検知レバー１０で検知するため、取付け位置や取付け高さに制限があった。スイッチ操作部６で蓋開閉検知レバー７をすくい上げるため、スイッチ操作部６は安全スイッチ４とほぼ同等な高さ配置しなければならなかった。
【０００７】
しかし、最近の洗濯機の高機能化に伴い、新機能を搭載する際、上部枠体２内部に機能部品を配置したくても上部枠体２の高さＨの制限があり、機能の高度化に制限があった。
【０００８】
本発明は上記従来の課題を解決するもので、洗濯機の高機能化に伴い上部枠体内の内蔵部品が増えて上部枠体が高くなり、スイッチ操作部が安全スイッチの取付け高さより極端に高くなっても、蓋の開閉により安全スイッチを確実にオン、オフできるようにし、安全性を確保することを目的としている。
【０００９】
【課題を解決するための手段】
本発明は上記目的を達成するために、洗濯機本体の上部を上部枠体により覆い、この上部枠体の開口部を蓋により開閉自在に覆い、上部枠体の内方部に少なくとも蓋の閉開に応じてオン、オフする安全スイッチを設け、蓋の後方にスイッチ操作部を延設するよう構成し、安全スイッチに設けた蓋開閉検知レバーとスイッチ操作部とを連動部材を介して連動させ、連動部材の一端を蓋開閉検知レバーに係止するとともに、他端をスイッチ操作部に引っ掛け、連動部材は上部枠体より延設したリブにて動きを規制するよう構成したものである。
【００１０】
これにより、洗濯機の高機能化に伴い上部枠体内の内蔵部品が増えて上部枠体が高くなり、スイッチ操作部が安全スイッチの取付け高さより極端に高くなっても、蓋の開閉により安全スイッチを確実にオン、オフできるようにし、安全性を確保することができる。

【００１７】
【実施例】
以下、本発明の一実施例について、図面を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。
【００１８】
図１に示すように、上部枠体１１は、洗濯機本体１の上部を覆い、洗濯機の高機能化に伴い多数の内蔵部品（図示せず）を設けており、この上部枠体１０の開口部１２を蓋３により開閉自在に覆っている。安全スイッチ４は上部枠体１１の内方部に設け、この安全スイッチ４に設けた蓋開閉検知レバー７と蓋３の後方に延設したスイッチ操作部６とを、連動部材１３を介して連動させ、連動部材１３の一端を蓋開閉検知レバー７に係止するとともに、他端をスイッチ操作部６に引っ掛け、連動部材１３は上部枠体１１より延設したリブ１６にて動きを規制するよう構成している。
【００１９】
連動部材１３は、ばね用ステンレ鋼線などの線材で構成し、図２に示すように、直径２ｍｍ程度の金属棒材の両端を反対方向に折り曲げ、この連動部材１３の端部に略直角の第１の折曲部１４ａを形成し、この折曲部１４ａより先端側にスイッチ操作部６の上面に引っ掛ける引掛部１５を形成し、蓋開時においては引掛部１５と第１の折曲部１４ａの間の部分を上部枠体１１より延設された第１のリブ１６ａの上部に設けた凹溝１７にはめ込む構成とすることにより、第１の折曲部１４ａの軌跡は凹溝１７によって規制され、スイッチ操作部６によって、引掛部１５を確実にすくい上げるよう構成している。
【００２０】
また、連動部材１３の一端１３ａを蓋開閉検知レバー７に設けた孔部７ａに挿着し、この連動部材１３の一端１３ａに第２の折曲部１４ｂを形成し、この第２の折曲部１４ｂより先端側に下方に凸となる凸部１８を設け、この凸部１８が上部枠体１１より延設された第２のリブ１６ｂに当接することにより、連動部材１３の後方への動きを規制するよう構成している。
【００２１】
また、連結部材１３の第１の折曲部１４ａと第２の折曲部１４ｂ間の略直線部１９を上部枠体１１より延設された第３のリブ１６ｃに当接することにより連動部材１３の倒れを規制するよう構成している。
【００２２】
ここで、連動部材１３の引掛部１５をスイッチ操作部６の上面に引っ掛けるのは、図３に示すように、蓋閉状態から、蓋３が所定の角度開かれた状態までの間としている。
【００２３】
また、図４に示すように、連動部材１３の第１の折曲部１４ａは略直線部１９と略直角に折り曲げ、さらに蓋３の軸方向に向けて水平方向に角度αをつけて、連動部材１１がスイッチ操作部６の後方に外れるのを防止するよう構成している。
【００２４】
また、図５に示すように、上部枠体１１に延設した凹溝１７の開口部１７ａの高さは、連動部材１３の一端１３ａを蓋開閉検知レバー７に取付けた状態で、蓋開閉検知レバー７を最も高く上げたときに位置する連動部材１３の他端１１ｂ側の高さより高くしている。

上記構成において動作を説明する。図１に示すように、蓋３が閉じているときは、連動部材１３の引掛部１５はスイッチ操作部６の上面に引っ掛けられ、連動部材１３が上方に引っ張られるため、安全スイッチ４の蓋開閉検知レバー７が押し上げられ、安全スイッチ４はオン状態にある。
【００２６】
つぎに、図３に示すように、蓋３を徐々に開くと、スイッチ操作部６が徐々に下がるため、連動部材１３を介して、開閉検知レバー７も徐々に下がる。所定の位置まで蓋開閉検知レバー７が下がると安全スイッチ４がオフとなり、脱水の動作が止まる。
【００２７】
このとき、連動部材１３は、上部枠体１１より延設した第１のリブ１６ａの上部に設けた凹溝１７にはめ込み、第２のリブ１６ｂおよび第３のリブ１６ｃにより動きを規制することで、スイッチ操作部６と安全スイッチ４に設けた蓋開閉検知レバー７とを連動させることができる。
【００２８】
このように本実施例によれば、安全スイッチ４に設けた蓋開閉検知レバー７とスイッチ操作部６とを連動部材１３を介して連動させ、連動部材１３の一端を蓋開閉検知レバー７に係止するとともに、他端をスイッチ操作部６に引っ掛け、連動部材１３は上部枠体１１より延設したリブ１６にて動きを規制するよう構成しているので、洗濯機の高機能化に伴い、上部枠体１１内の内蔵部品が増えて上部枠体１１が高くなり、スイッチ操作部６が安全スイッチ４の取付け高さより極端に高くなって、安全スイッチ４に設けた蓋開閉検知レバー７とスイッチ操作部６との高さが違うようになっても、連動部材１３を介して、蓋３の開閉により確実に安全スイッチをオン、オフすることができ、安全性を確保することができる。
【００２９】
また、連動部材１３の他端は略直角に折り曲げた第１の折曲部１４ａを有し、この第１の折曲部１４ａより先端側をスイッチ操作部６の上面に引っ掛け、蓋開時に引掛部１５と第１の折曲部１４ａの間の部分を上部枠体１１より延設した第１のリブ１６ａの上部に設けた凹溝１７に係合するよう構成しているので、第１の折曲部１４ａの軌跡は凹溝１７に沿って規制され、スイッチ操作部６によって確実にすくい上げることができ、蓋３の開閉により確実に安全スイッチ４をオン、オフすることができる。
【００３０】
また、連動部材１３の一端１３ａは第２の折曲部１４ｂを有し、この第２の折曲部１４ｂより先端側に下方に凸となる凸部１８を設け、この凸部１８を上部枠体１１より延設した第２のリブ１６ｂに当接させ、連動部材１３の後方への部材の動きを規制するよう構成しているので、連動部材１３の後方への部材の動きを規制することができる。
【００３１】
また、連結部材１３の第１の折曲部１４ａと第２の折曲部１４ｂ間の略直線部１９を上部枠体１１より延設した第３のリブ１６ｃに当接させ、連動部材１３の横方向への動きを規制するよう構成しているので、連動部材１３の倒れを規制することができて、スイッチ操作部６から外れるのを防止することができる。
【００３２】
また、上部枠体１１に延設された凹溝１７の開口部１７ａの高さは、連動部材１３の一端を蓋開閉検知レバー７に取付けた状態で、蓋開閉検知レバー７を最も高く上げたときに位置する連動部材１３の他端側の高さより高くしているので、安全スイッチ４を上部枠体１１に螺結した後は連動部材１３が上部枠体１１から外れるのをなくすることができる。
【００３３】
また、連動部材１３の第１の折曲部１４ａは略直線部１９と略直角に折り曲げ、さらに蓋３の軸方向に向けて水平方向に角度をつけたので、連動部材１３がスイッチ操作部６の後方に外るのを防止でき、確実にすくい上げることができ、蓋３の開閉により確実に安全スイッチ４をオン、オフすることができる。
【００３４】
【発明の効果】
以上のように、本発明の請求項１に記載の発明によれば、安全スイッチに設けた蓋開閉検知レバーとスイッチ操作部とを連動部材を介して連動させ、連動部材の一端を蓋開閉検知レバーに係止するとともに、他端をスイッチ操作部に引っ掛け、連動部材は上部枠体より延設したリブにて動きを規制するよう構成したことにより、洗濯機の高機能化に伴い上部枠体内の内蔵部品が増えて上部枠体が高くなり、スイッチ操作部が安全スイッチの取付け高さより極端に高くなっても、蓋の開閉により安全スイッチを確実にオン、オフできるようにし、安全性を確保することができる。
