【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4および図5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4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4に示すように、蓋3が閉じている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5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】

【0019】
【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。
【0020】
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を介して連動している。
【0021】
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。
【0022】
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。
【0023】
また、連部材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。
【0024】
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。
【0025】
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の開閉により安全スイッチ4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は、金属棒材にて構成しているので、強度を強くでき、安価でコンパクトに構成することができる。
【0030】
また、連動部材13の一端は、安全スイッチ4の蓋開閉検知レバー7の先端部近傍に係止するよう構成しているので、蓋開閉検知レバー7の回動角度の変化を連結部材13の上下の移動距離によって検知することができ、角度に対する移動距離が大きくなり、開閉角度を細かく検知することができる。
【0031】
また、連動部材13の一端は、開閉検知レバー7の先端部近傍に設けた孔部7aに挿着するよう構成しているので、連動部材13を確実に蓋開閉検知レバー7に連動することができる。
【0032】
また、連動部材13の他端は、スイッチ操作部6の上面に引っ掛けるよう構成しているので、簡単な構造で蓋3の回動を容易に検知することができる。
【0033】
また、連動部材13の他端は、蓋閉状態から蓋3が所定の角度開かれた状態までの間で、スイッチ操作部6の上面に引っ掛けるよう構成しているので、蓋3の開閉に伴う連動部材13の動きが単純になり、蓋3の開閉により安全スイッチ4を確実にオン、オフすることができ、安全性を確保することができる。
【0034】
また、連動部材13の第2の折曲部14bより先端側に下方に凸となる凸部18を設けているので、蓋3の上方など外部から水滴が浸入しても下方の凸部18で水滴は落下し、直接安全スイッチ4に付着するのを防止することができ、安全性を向上することができる。
【0035】
また、連動部材13はばね用ステンレス鋼の線材で構成しているので、使用者の激しい蓋3の開閉による連結部材13の変形を回避することができる。
【0036】
【発明の効果】
以上のように、本発明の請求項1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るようにし、また連動部材の動きを規制する凹溝を上部に有する第1のリブを上部枠体に設けたことから、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。
