Description

【０００１】
【発明の属する技術分野】
本発明は、洗濯機内に発生した黒かび等の異物を洗浄する洗濯機の洗浄方法に関する。
【０００２】
【従来の技術】
従来、洗濯機は図６に示すように構成していた。以下、その構成について説明する。
【０００３】
図６に示すように、外槽１は、底部に撹拌翼２を回転自在に配設した洗濯槽３を内包し、吊り棒４により洗濯機外枠５に吊り下げている。モータ６は、Ｖベルト７および減速機構兼クラッチ８を介して、撹拌翼２や洗濯槽３を駆動する。給水弁９は洗濯槽３内に給水するもので、排水弁１０は洗濯槽３内の洗濯水を排水するもので、水位検知手段１１は外槽１内の水位を検知するものである。
【０００４】
撹拌翼２の裏羽根１２の外周部にはポンプ室１３が形成されており、洗濯槽３内の洗濯水をポンプ室１３から循環水路１４を経由して糸くずフィルター１５に送水する。カバー体１６は、外槽１の上部に設けたもので、制御装置１７は、モータ６、給水弁９、排水弁１０などを制御して、洗濯、すすぎ、脱水の各行程を逐次制御するものである。
【０００５】
上記構成の洗濯機で洗濯を行うと、洗濯物から出る汚れ成分や、洗剤成分の一部が水道水中の金属イオンと結合し、金属石けんを生成し、外槽１や、洗濯槽３、撹拌翼２などに付着する。さらに、洗濯を繰り返すと、付着した金属石けんに洗濯物に含まれる微生物が作用し、洗濯槽３の外壁や外槽１の内壁、撹拌翼２の裏面等の隠れた部分に、バイオフィルムや黒かび等の異物が発生し、この異物が堆積したものが、洗濯中の水流で剥がれて、洗濯物を汚すことがあった。
【０００６】
この異物を除去する方法として、漂白成分を主体とする洗濯槽洗浄剤があるが、その使用方法は、給水弁９と水位検知手段１１を作動して、洗濯槽３内にできるだけ高い水位まで給水した後、洗浄剤を投入し、撹拌翼２を回転し、洗浄剤を溶かした後、数時間つけおいて、洗浄剤を異物に作用させて異物を剥がし、排水弁９を作動して排液する。その後、洗濯槽３をすすぐため、洗濯槽３内に設定水位まで給水し、撹拌翼２を回転させるためすすぎを行い、その後排水するのが、一般的である。
【０００７】
【発明が解決しようとする課題】
しかしながら、この方法の場合、洗浄行程である長時間のつけおき行程は手動で行い、その後自動ですすぎ行程を実施するため大変面倒であり、さらに、洗濯槽洗浄時の水位よりも下、すなわち数時間つけおき時の洗浄液に浸かった部分の異物しか除去できず、撹拌翼２の回転で発生する水位変動分の水位よりも上部に発生した異物が除去できないという問題があった。また、一旦、剥がれた異物が、すすぎ行程で十分に排出や回収ができず、洗濯機内に残留し、つぎの洗濯のときに、洗濯物に付着し汚すという問題があった。
【０００８】
本発明は上記課題を解決するもので、長時間のつけおき行程を有する洗い行程とすすぎ行程を自動で実施可能とし、洗濯機内に発生した異物を除去できるように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、洗濯槽およびこの洗濯槽の底部に回転自在に配設した撹拌翼とこれを内包した外槽内とを洗浄剤を含む洗浄液で洗う洗い行程と、この洗い行程の後に実行するすすぎ行程とを有し、洗い行程は所定の濃度の洗浄液を洗濯槽および外槽内で作る行程と、撹拌翼の間欠的な反転回転を伴うつけおき行程とを実行し、ついで洗濯槽内の洗浄液の排水行程を有するすすぎ行程をこの順序で実行する洗濯機の洗浄方法である。
【００１０】
これにより、従来の手動でのつけおきに比べ、つけおき行程中に撹拌翼を反転回転させるので水流が発生でき、洗濯槽の外壁や外槽の内壁に発生した異物をより多く剥がすことができ、自動化にすることで面倒な行程を容易に実施でき、洗濯機内に発生した異物を除去することができる。
【００１１】
【発明の実施の形態】
本発明の請求項１に記載の発明は、洗濯槽およびこの洗濯槽の底部に回転自在に配設した撹拌翼とこれを内包した外槽内とを洗浄剤を含む洗浄液で洗う洗い行程と、この洗い行程の後に実行するすすぎ行程とを有し、前記洗い行程は所定の濃度の洗浄液を洗濯槽および外槽内で作る行程と、前記撹拌翼の間欠的な反転回転を伴うつけおき行程とを実行し、ついで洗濯槽内の洗浄液の排水行程を有するすすぎ行程をこの順序で実行する洗濯機の洗浄方法であり、従来の手動でのつけおきに比べ、つけおき行程中に撹拌翼を反転回転させるので水流が発生でき、洗濯槽の外壁や外槽の内壁に発生した異物をより多く剥がすことができ、自動化にすることで面倒な行程を容易に実施でき、洗濯機内に発生した異物を除去することができる。
【００１２】
請求項２に記載の発明は、上記請求項１に記載の発明において、つけおき行程は、水位を通常洗濯水位より高い水位とし、撹拌翼の反転回転と回転停止とを交互に実行する洗濯機の洗浄方法であり、通常洗濯水位より高い水位にて、撹拌翼の反転回転と回転停止とを繰り返すので、洗浄液を撹拌して洗濯槽の水面中央部が下降するとともに、洗濯槽と外槽の間の水面が上昇するので、通常洗濯の水位よりも上部の洗濯槽の外壁や外槽の内壁に発生した異物にも洗浄液を作用させ、剥がすことができる。
【００１３】
請求項３に記載の発明は、上記請求項１または２に記載の発明において、つけおき行程の後に、撹拌翼で洗濯槽内の洗浄液を撹拌する撹拌行程を実行する洗濯機の洗浄方法であり、つけおき行程で剥がれた異物を、撹拌翼の回転により糸くずフィルター内に回収することができる。
【００１４】
請求項４に記載の発明は、上記請求項１に記載の発明において、すすぎ行程は、給水行程と排水行程を同時に作動させながら洗濯槽を低速回転させる槽回転すすぎ行程と、少量の水にて撹拌翼を撹拌する第１の撹拌すすぎ行程と、この第１の撹拌すすぎ行程よりも高いつけおき行程の水位で行う第２の撹拌すすぎ行程と、排水行程とをこの順序で少なくとも１回実行する洗濯機の洗浄方法であり、少量の水量で撹拌翼を回転させるので、強力な水流が起こり、剥がれた異物が細かく粉砕され、洗濯槽外に移動しやすくなり、ついで、第１の撹拌すすぎ行程よりも高いつけおき行程の水位で撹拌翼を回転させるので、糸くずフィルターを通過する水の量を多くすることができ、粉砕された多くの異物を糸くずフィルター内に回収しやすくなるので、剥がれた異物を洗濯機内に残留させないようにできる。
【００１５】
請求項５に記載の発明は、上記請求項４に記載の発明において、第２の撹拌すすぎ行程の前か後の少なくとも１回、槽回転すすぎ行程を実行する洗濯機の洗浄方法であり、洗濯槽の外壁上部や外槽の内壁上部に付着している剥がれた異物を洗濯槽および外槽外に排水として洗い流すことができる。
【００１６】
請求項６に記載の発明は、上記請求項４または５に記載の発明において、第２の撹拌すすぎ行程は、つけおき行程の水位より高い水位で実行する洗濯機の洗浄方法であり、洗濯槽の外壁上部や外槽の内壁上部に付着している剥がれた異物を洗濯槽内に洗い流すことができ、さらに、つけおき行程より水位を高くすることで、つけおき行程の水流により洗浄液が付いた洗濯槽や外槽の上部を綺麗にすすぐことができる。
【００１７】
請求項７に記載の発明は、上記請求項４〜６に記載の発明において、槽回転すすぎ行程に代えて、撹拌すすぎ行程に先立って、給水と排水をほぼ同時に行う給排水行程を実行する洗濯機の洗浄方法であり、洗い行程後、撹拌翼上に残留した異物を給水と同時に排水することにより洗濯槽および外槽外に排出し、その後のすすぎ行程を効率よく行うことができる。
【００１８】
請求項８に記載の発明は、上記請求項４〜７に記載の発明において、すすぎ行程の排水行程に先立って、注水すすぎを実行する洗濯機の洗浄方法であり、洗い行程やすすぎ行程で回収や排出できなかった異物を確実に排出することができる。
【００１９】
請求項９に記載の発明は、上記請求項４〜７に記載の発明において、すすぎ行程の第２の撹拌すすぎ行程に代えて、注水すすぎを実行する洗濯機の洗浄方法であり、洗い行程やすすぎ行程で回収や排出できなかった異物を確実に排出することができる。
【００２０】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。なお、従来例と同じものは、同一記号を付して説明を省略する。
【００２１】
（実施例１）
図１に示すように、制御装置１８は、モータ６、給水弁９、排水弁１０、などの動作を制御して、洗い、すすぎ、脱水行程を逐次制御するとともに、洗浄剤を含む洗浄液で洗う洗い行程と、この洗い行程の後にすすぎ行程を実行し、洗濯槽３およびこの洗濯槽３の底部に回転自在に配設した撹拌翼２とこれを内包した外槽１内とを洗浄するようにしている。
【００２２】
洗い行程は所定の濃度の洗浄液を洗濯槽３および外槽１内で作る洗浄液作成行程と、撹拌翼２の間欠的な反転回転を伴うつけおき行程とを実行し、ついで洗濯槽３内の洗浄液の排水行程を有するすすぎ行程をこの順序で実行するようにしている。
【００２３】
ここで、つけおき行程は、水位を通常洗濯水位より高い所定の水位Ｐ１とし、撹拌翼２の反転回転と回転停止とを交互に実行するようにしている。また、つけおき行程の後に、撹拌翼２で洗濯槽３内の洗浄液を撹拌する撹拌行程を実行するようにしている。
【００２４】
上記構成において図１および図２を参照しながら動作を説明する。ステップ２０でスタートスイッチ（図示せず）を押すと、洗い行程の洗浄液作成行程に入り、ステップ２１で給水弁９と水位検知手段１１により、洗濯槽３内に通常洗濯水位より高い所定水位Ｐ１まで給水し、給水弁９の作動を停止する。ステップ２２で洗浄剤を投入し、ステップ２３でモータ５により撹拌翼２を所定時間反転回転させ、洗浄剤の溶解を行うとともに、均一な濃度の洗浄液を作成する。
【００２５】
つづいて、撹拌翼２の間欠的な反転回転を伴うつけおき行程に入り、ステップ２４でモータ５により撹拌翼２をオン、オフ制御にて左右反転回転させる。撹拌翼２の左右反転回転により洗濯槽３の洗浄液を撹拌する力が増大し、撹拌翼２のオン時に洗濯槽３内の水面は中央部が下降し、外側、つまり、洗濯槽３と外槽１の間の水面が上昇する。
【００２６】
このとき、洗濯槽３と外槽１の間の水面は所定水位Ｐ１より若干上昇し、洗濯槽３の外壁や、外槽１の内壁にも洗浄剤が行きわたる。逆にオフ時には、洗濯槽３内の水面は戻り、洗濯槽３と外槽１の間の水面が若干下降する。
【００２７】
その後、ステップ２５で、つけおき行程の内の撹拌翼３の反転回転を停止するつけおきを所定時間実行し、洗浄液を異物に十分作用させる。ステップ２６にて、ステップ２４の動作とステップ２５の動作を所定回数繰り返すことにより、洗浄剤を行きわたらせるとともに、撹拌翼２の反転回転で形成する水流にて異物を剥がして行く。
【００２８】
その後の撹拌行程に入り、ステップ２７で、撹拌翼２を反転回転させ、洗濯兼脱水槽３内の洗浄液をポンプ室１３から循環水路１４を経由して、糸くずフィルター１５に送水し、洗浄液に含まれる異物を糸くずフィルター１５に回収する。このとき、同時に、洗浄液により、撹拌翼２の裏面、ポンプ室１３から循環水路１４などに堆積した異物を剥がし、糸くずフィルター１５に回収することができる。
【００２９】
ついで、排水行程に入り、ステップ２８で排水弁１０を作動させ、洗濯槽３内の洗浄液を排水し、その後、ステップ２９ですすぎ行程に移行する。
【００３０】
このように、つけおき行程で、撹拌翼２を間欠的に反転回転させることによって水流が発生でき、洗濯槽３の外壁や外槽１の内壁に発生した異物をより多く剥がすことができ、自動化することで面倒な行程を容易に実施でき、洗濯機内に発生した異物を除去することができる。
【００３１】
また、つけおき行程は、水位を通常洗濯水位より高い水位とし、撹拌翼２の反転回転と回転停止とを交互に実行することにより、洗浄液を撹拌して洗濯槽３の水面中央部が下降するとともに、洗濯槽３と外槽１の間の水面が上昇するので、通常洗濯の水位よりも上部の洗濯槽３の外壁や外槽１の内壁に発生した異物にも洗浄液を作用させることができ、高い面まで剥がすことができる。
【００３２】
また、つけおき行程の後に、撹拌翼２で洗濯槽３内の洗浄液を撹拌する撹拌行程を実行することにより、つけおき行程で剥がれた異物を、撹拌翼２の回転により糸くずフィルター１５内に回収することができる。
【００３３】
なお、本実施例では、洗浄液作成行程の水位とつけおき行程の水位とを同じにしているが、洗浄液作成行程の水位をたとえば通常洗濯水位とし、つけおき行程に入ったとき、通常洗濯水位より高い水位まで追加給水するようにしてもよく、この場合は、洗浄液作成行程にて短時間で洗浄剤を溶解することができる。
【００３４】
（実施例２）
図３に示すように、制御装置２９は、モータ６、給水弁９、排水弁１０などの動作を制御し、洗い、すすぎ、脱水行程を逐次制御するとともに、洗浄剤を含む洗浄液で洗う洗い行程と、この後にすすぎ行程を実行して、洗濯槽３およびこの洗濯槽３を内包した外槽１内を洗浄するようにし、すすぎ行程は、給水弁９と排水弁１０を同時に動作させながら洗濯槽３を低速回転させる槽回転すすぎ行程と、少量の水にて撹拌翼２を撹拌する第１の撹拌すすぎ行程と、この第１の撹拌すすぎ行程よりも高いつけおき行程の水位で行う第２の撹拌すすぎ行程と、排水行程とをこの順序で少なくとも１回実行するようにしている。
【００３５】
また、すすぎ行程の排水行程に先立って、注水すすぎを実行するようにしている。他の構成は上記実施例１と同じであり、同一符号を付して説明を省略する。
【００３６】
上記構成において図３および図４を参照しながら動作を説明する。洗い行程終了後、すすぎ行程に入り、ステップ３１で給水弁９と排水弁１０を同時に作動させながら洗濯槽３を低速回転させる槽回転すすぎ行程を実施し、洗い行程終了後に撹拌翼２上や洗濯槽３の外壁底部や外槽１の内壁底面に残留した異物を排水とともに排出する。このとき、槽回転すすぎの行程の代わりに、給水弁９と排水弁１０を動作させて、給水と排水をほぼ同時に行う給排水行程を実行してもよい。
【００３７】
つぎに、ステップ３２で、給水弁９と水位検知手段１１により、少量水位Ｐ２まで給水し、ステップ３３でモータ６により、撹拌翼２を所定時間反転回転させる第１の撹拌すすぎ行程を実行し、洗濯槽３と外槽１の間に残留している異物を洗浄液に拡散することができる。このとき、少量の水量で撹拌翼２を反転回転させるので、強力な水流が起り、剥がれた異物は細かく粉砕される。
【００３８】
つぎに、ステップ３４で、給水弁９と水位検知手段１１により、第１の撹拌すすぎ行程よりも高く、洗い行程のつけおき行程の水位Ｐ１まで給水し、ステップ３５でモータ６により、撹拌翼２を所定時間反転回転させる第２の撹拌すすぎ行程を実行し、少量水位Ｐ２よりも上の洗濯槽３と外槽１の間に残留している異物を洗い流すとともに洗浄液内に拡散する。
【００３９】
ここで、撹拌翼２を所定時間回転させるため、洗濯兼脱水槽３内の洗浄液をポンプ室１３から循環水路１４を経由して、糸くずフィルター１５に送水する。ステップ３３で異物は細かく粉砕されているので、水と一緒に糸くずフィルター１５に流入し、糸くずフィルター１５に回収される。また、このとき、高水位Ｐ１で撹拌翼２を反転回転しているので、糸くずフィルター１５を通過する水の量が多く、異物を回収しやすい。
【００４０】
つぎに、ステップ３６で給水弁９と排水弁１０を作動させながら、撹拌翼２を回転させ、注水すすぎを実行する。前行程までで、排出、回収できなかった異物を排水とともに確実に排出する。ステップ３７で、排水弁９を作動させ、外槽１内の水を排出する。
【００４１】
このように、洗い行程後、第１の撹拌すすぎ行程の前に給水弁９と排水弁１０を同時に動作させながら、洗濯槽３を低速回転する槽回転すすぎ行程を実行することにより、撹拌翼２上や洗濯槽３の外壁底部や外槽１の内壁底面に残留した異物を、給水と同時に排水することに外槽１外に排出することができるので、その後のすすぎ行程を効率よく行うことができる。
【００４２】
このとき、槽回転すすぎの行程の代わりに、給水弁９と排水弁１０を動作させて、給水と排水をほぼ同時に行う給排水行程を実行しても、同様の作用効果を得ることができる。
【００４３】
また、第１の撹拌すすぎ行程で、少量の水量で撹拌翼２を反転回転させるので、強力な水流が起こり、剥がれた異物が細かく粉砕され、洗浄液内に拡散され、外槽１外に移動しやすくなっており、つぎに、つけおき行程の水位Ｐ１まで給水し、撹拌翼２を所定時間反転回転させ、少量水位Ｐ２よりも上の洗濯槽３と外槽１の間に残留している異物を洗い流すとともに洗浄液内に拡散し、糸くずフィルター１５を通過する水の量を多くすることができ、異物を糸くずフィルター１５内に回収することができる。
【００４４】
また、注水すすぎを行うことにより、洗い行程やすすぎ行程で回収や排出できなかった異物を排出することができるので、洗濯機内に異物が残留するのを防止することができる。
【００４５】
なお、本実施例では、槽回転すすぎ行程、または槽回転すすぎの行程の代わりに実行する給排水行程は、第１の撹拌すすぎ行程の前で実行しているが、要は異物を外槽１外にうまく排出するのが目標であり、第２の撹拌すすぎ行程の前か後に実行するようにしても、同様の作用効果を得ることができる。
【００４６】
また、本実施例では、第２の撹拌すすぎ行程の後に、注水すすぎを実行しているが、第２の撹拌すすぎ行程に代えて、注水すすぎを実行してもよく、同様の作用効果を得ることができる。
【００４７】
（実施例３）
図５に示すように、制御装置３８は、モータ６、給水弁９、排水弁１０などの動作を制御し、洗い、すすぎ、脱水行程を逐次制御するとともに、洗浄剤を含む洗浄液で洗う洗い行程と、この後にすすぎ行程を実行して、洗濯槽３およびこの洗濯槽３を内包した外槽１内を洗浄するようにし、すすぎ行程は、少量の水にて撹拌翼２を撹拌する第１の撹拌すすぎ行程と、この第１の撹拌すすぎ行程よりも高く、洗い行程のつけおき行程の水位Ｐ１よりも高い水位Ｐ３にて第２の撹拌すすぎ行程を実行するようにし、つぎに排水行程を順次実行するようにしている。他の構成は上記実施例２と同じであり、同一符号を付して説明を省略する。
【００４８】
上記構成において動作を説明する。第１の撹拌すすぎ行程で、少量の水量で撹拌翼２を反転回転させるので、強力な水流が起こり、剥がれた異物が細かく粉砕され、洗浄液内に拡散されて外槽１外に移動しやすくなっている。
【００４９】
