【発明の属する技術分野】
本発明は、洗濯兼脱水槽に液体洗剤を投入する洗剤投入装置を有する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９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９に示すように、洗濯兼脱水槽１は、底面に撹拌翼２を回転自在に配設し、この洗濯兼脱水槽１の外側に水受け槽３を設けている。水受け槽３の底面には洗濯兼脱水槽１と撹拌翼２を駆動するモータ４を取り付け、駆動部の切り替えを行うクラッチ装置５を介して洗濯兼脱水槽１または撹拌翼２を駆動するように構成している。また、水受け槽３は、外
郭６にサスペンション７を介して防振支持している。
【０００４】
洗濯兼脱水槽１の上部には、液体を内封した流体バランサー８を固定し、水受け槽３の上面は、水受け槽カバー９によって覆われている。水受け槽３を防振支持している外郭６の上部は、制御装置１０、給水弁１１、給水経路１２等を収納した外郭カバー１３によって覆われている。この外郭カバー１３内に、液体洗剤１４を収容した洗剤タンク１５を設けている。
【０００５】
洗剤タンク１５は、液体洗剤１４を補給する補給口１５ａを洗剤タンク蓋１６によりパッキング（図示せず）を介して閉じて、洗剤タンク１５内を密閉できるようにし、空気流入口１５ｂと液体排出口１５ｃとを有している。空気ポンプ１７は、洗剤タンク１５の空気流入口１５ａに連通し、この空気ポンプ１７によって、密閉した洗剤タンク１５内の空気圧を高めるようにしている。
【０００６】
逆止弁１８は、洗剤タンク１５の空気流入口１５ｂと空気ポンプ１７との間に、洗剤タンク１５内の液体洗剤１４が空気ポンプ１７に逆流しない方向に設けている。制御装置１０は、ユーザーの好みの水量、あるいは自動コース運転において自動設定された水量に合わせて、空気ポンプ１７を動作させ、液体洗剤１４を洗濯兼脱水槽１に投入するように構成している。
【０００７】
上記構成において、洗濯兼脱水槽１内に洗濯物を投入し、ユーザーがキー操作により好みの水量を設定するか、あるいは自動コースを選んで自動設定した水量で運転を開始すると、制御装置１０は、所定水量に対応して、空気ポンプ１７を所定時間動作させ、密閉した洗剤タンク１５内の空気圧を逆止弁１８を介して高め、洗剤タンク１５内の液体洗剤１４を液体排出口１５ｃより押し出し、洗濯兼脱水槽１内の洗濯物の量に応じた液体洗剤１４を洗濯兼脱水槽１に投入する。
【０００８】
【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、一度に投入される液体洗剤の量は、設定した水量に応じた空気ポンプ１７の動作時間で決まるため、逆止弁１８の形状ばらつきに大きく影響され、投入量がばらついて、少ないときは洗浄力が出なかったり、多いときはすすぎ性能が低下したり、洗剤を無駄にしてしまうという問題があった。
【０００９】
本発明は上記従来の課題を解決するもので、投入する液体洗剤量のばらつきを抑え、洗浄性能、すすぎ性能を向上させ、洗剤の無駄を防止することを目的としている。
【００１０】
【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、水受け槽内に回転自在に洗濯兼脱水槽を配設し、水受け槽を防振支持する外郭の上部に水受け槽を覆うように外郭カバーを設け、少なくとも２回の洗濯に使用できる量の液体洗剤を収容可能な洗剤タンクを外郭カバー内に設け、洗剤タンクの下部と連通して第１の所定高さに位置し洗剤タンク内の液体洗剤を排出する液体排出口を設け、洗剤タンク内に液体洗剤を補給する補給口を第１の所定高さより高い第２の所定高さの位置に設け、ポンプ装置により洗剤タンク内の空気室の空気圧を高めることで液体洗剤を液体排出口より排出して洗濯兼脱水槽内に投入し、洗剤タンクとポンプ装置とを密封管により連結し、密封管は、第１の所定高さより高い第３の所定高さの位置で洗剤タンクに連結され、洗剤タンク内に満水である第１の所定高さまで液体洗剤が入れられた場合においても、密封管が連結する洗剤タンクの内部に空気が残留し空気溜め部が形成されるとともに、洗濯機本体を前後左右のいずれかの真横に転倒させたとき、前後左右のいずれの転倒状態においても、密封管の少なくとも一部が洗剤タンク内の液体洗剤の水面より高い位置関係を維持するよう構成したものである。
【００１１】
これにより、投入する液体洗剤量のばらつきを抑え、洗浄性能、すすぎ性能を向上させることができ、洗剤の無駄を防止することができるとともに、ポンプ装置の故障が引き起こされる不具合を防止することができる。
【００１２】
【発明の実施の形態】
本発明の請求項１に記載の発明は、水受け槽内に回転自在に配設した洗濯兼脱水槽と、前記水受け槽を防振支持する外郭と、前記外郭の上部に前記水受け槽を覆うように設けた外郭カバーと、前記外郭カバー内に設けられ少なくとも２回の洗濯に使用できる量の液体洗剤を収容可能な洗剤タンクと、前記洗剤タンクの下部と連通して第１の所定高さに位置し前記洗剤タンク内の液体洗剤を排出する液体排出口と、前記第１の所定高さより高い第２の所定高さの位置に設けられ前記洗剤タンク内に液体洗剤を補給する補給口と、前記洗剤タンク内の空気室の空気圧を高めることで液体洗剤を前記液体排出口より排出して前記洗濯兼脱水槽内に投入するポンプ装置と、前記洗剤タンクと前記ポンプ装置を連結する密封管とを備え、前記密封管は、前記第１の所定高さより高い第３の所定高さの位置で前記洗剤タンクに連結され、前記洗剤タンク内に満水である前記第１の所定高さまで液体洗剤が入れられた場合においても、前記密封管が連結する前記洗剤タンクの内部に空気が残留し空気溜め部が形成されるとともに、洗濯機本体を前後左右のいずれかの真横に転倒させたとき、前記前後左右のいずれの転倒状態においても、前記密封管の少なくとも一部が前 記洗剤タンク内の液体洗剤の水面より高い位置関係を維持するように構成したものであり、洗剤タンク内の液体洗剤が空気ポンプに逆流しようとしても、密封管の内部に残留した空気により液体洗剤の流れを遮断することができて、逆止弁などを用いることなく空気ポンプへの液体洗剤の逆流を防止することができ、投入する液体洗剤量のばらつきを抑え、洗浄性能、すすぎ性能を向上させることができ、洗剤の無駄を防止することができるとともに、洗濯機本体の運搬時、設置時、補修時などで洗濯機本体を傾斜させたり、前後左右に転倒させても、ポンプ装置への液体洗剤の流入を防止することができるので、ポンプ装置の故障が引き起こされる不具合を防止することができる。
【００１３】
【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、従来例と同じ構成のものは同一符号を付して説明を省略する。
【００１４】
（実施例１）
図１に示すように、外郭カバー１９は、外郭６の上部を覆い、制御装置１０、給水弁１１、給水経路１２などを設けている。この外郭カバー１９内に、少なくとも２回の洗濯に使用できる量の液体洗剤２０を収容した洗剤タンク２１を設けている。洗剤タンク２１は、液体洗剤２０を補給する補給口２１ａを洗剤タンク蓋２２によりパッキング（図示せず）を介して閉じて、洗剤タンク２１内を密閉できるようにし、空気流入口２１ｂと液体排出口２１ｃとを有している。
【００１５】
空気ポンプ（ポンプ装置）２３は、洗剤タンク２１内の液体洗剤２０を洗濯兼脱水槽１内に投入するもので、ピストン式、弁式などで構成し、密封管２４により直結した洗剤タンク２１の空気流入口２１ａに連通して、この空気ポンプ２３によって、密閉した洗剤タンク２１内の空気圧を高めるようにしている。ここで、密封管２４は、洗剤タンク２１内の液体洗剤２０の液面より高くなる空気溜め部２４ａを形成し、内部に空気が残留するよう構成している。
【００１６】
制御装置１０は、洗濯兼脱水槽１に投入された洗濯物（衣類）の量を判定する布量判定手段（図示せず）を有しており、この布量判定手段により判定された判定結果に応じて、つまりは洗濯物の量、または洗濯物の量に合わせた水量の少なくとも一方に合わせて、空気ポンプ２３を動作させ、液体洗剤２０を洗濯兼脱水槽１に投入するように構成している。
【００１７】
上記構成において、洗濯兼脱水槽１内に洗濯物を投入し、運転を開始すると、制御装置１０はモータ４を駆動して撹拌翼２を回転させ、モータ４への通電をオフした後の惰性回転におけるモータ４の減速の度合いより、洗濯兼脱水槽１内の洗濯物の量を判定する。この判定結果に基づいて、空気ポンプ２３を所定時間動作させ、密閉した洗剤タンク２１内の空気圧を高め、洗剤タンク２１内の液体洗剤２０を液体排出口２１ｃより押し出し、洗濯兼脱水槽１内の洗濯物の量に応じた液体洗剤２０を洗濯兼脱水槽１に投入する。
【００１８】
液体洗剤２０を投入した後は、密封管２４内には、少なくとも空気溜め部２４ａに空気が残留しているため、洗剤タンク２１内の液体洗剤２０が空気ポンプ２３に逆流しようとしても、密封管２４の空気溜め部２４ａ内に残留した空気により液体洗剤２０の流れを遮断することができて、逆止弁などを用いることなく空気ポンプ２３への液体洗剤２０の逆流を防止することができる。
【００１９】
その後、制御装置１０によりモータ４、給水弁１１などの動作を制御し、洗濯、すすぎ、脱水の一連の行程を逐次制御し、洗濯物を洗濯した後、すすぎ、脱水する。
【００２０】
これによって、空気ポンプ２３と洗剤タンク２１は、途中介在物なく、密封管２４により直結し連通しているため、空気ポンプ２３の応答精度を高めて、投入する洗剤量のばらつきを抑えることができ、洗浄性能、すすぎ性能を向上させることができ、なおかつ洗剤の無駄を防止することができる。
【００２１】
（実施例２）
図２〜図４に示すように、洗剤タンク２５は、液体洗剤２０を補給する補給口２５ａを洗剤タンク蓋２２によりパッキング（図示せず）を介して閉じて、洗剤タンク２５内を密閉できるようにし、空気流入口２５ｂ、液体排出口２５ｃと空気室２５ｄとを有している。
【００２２】
空気ポンプ２３は、洗剤タンク２５内の液体洗剤２０を洗濯兼脱水槽１内に投入するもので、ピストン式、弁式等で構成し、密封管２６により直結した洗剤タンク２５の空気流入口２５ａに連通して矢印方向に空気を送り込み、この空気ポンプ２３によって、密閉した洗剤タンク２５内の空気圧を高めるようにしている。
【００２３】
密封管２６は、洗剤タンク２５の天面全体の略外形に沿って引き回し、洗濯機本体を前後左右に転倒させても、洗剤タンク２１内の液体洗剤２０の液面より少なくとも一部が高くなるように配設している。洗剤保持ケース２７は、予約時等直接衣類に洗剤原液を掛けないよう配慮している引き出し式のケースである。
【００２４】
２５ｅは洗剤タンク２５の基準面であり、この基準面２５ｅからの各々の高さは、補給口２５ａまでをｆ、空気流入口２５ｂまでをｇ、液体排出口２５ｃまでをｈ、空気ポンプ２３までをｉとすると、ｈ＜ｆ、ｈ＜ｇ、ｈ＜ｉの位置関係に構成しており、万一、補給口２５ａから液体洗剤２０を入れ過ぎても、その分は液体排出口２５ｃより自然に排出される。
【００２５】
空気室２５ｄは、洗剤タンク２５内に液体洗剤２０が満水で洗剤タンク蓋２２を閉めた状態を最小容積として洗剤タンク２５内に設けている。
【００２６】
上記構成において、洗剤タンク２５内の液体洗剤２０の満水時に洗濯機本体を矢印の鉛
直下方に対して、図５に示すように前面倒し、図６に示すように後面倒し、図７に示すように左側面倒し、図８に示すように右側面倒しを行っても、密閉管２６は、空気室２５ｄの最小容積により、液体洗剤２０（斜線部）の液面２０ａ（波線）より密封管２６の一部２６ａが高い位置関係を維持するように配設されている。
【００２７】
これによって、洗剤タンク２５内に液体洗剤２０を残したまま洗濯機本体の運搬時、設置時、補修時等で洗濯機本体を傾けたり、倒す場合や、液体洗剤２０の補給時に液体洗剤２０が空気ポンプ２３内に流入するのを防止でき、液体洗剤２０の有機成分や界面活性剤等によって空気ポンプ２３の故障が引き起こされる不具合を防止することができる。
【００２８】
