Description

【０００１】
【発明の属する技術分野】
本発明は、洗濯、すすぎ、脱水の一連の行程を自動的に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１２および図１３に示すよう構成していた。以下、その構成について説明する。
【０００３】
図１２に示すように、外槽１は、底部にパルセーター２を回転自在に配設した洗濯兼脱水槽３を内包し、吊り棒４により洗濯機外枠５に防振支持されている。外槽１の底面には、洗濯兼脱水槽３とパルセーター２を駆動するモータ６を有し、また、上方には外槽１を覆う外槽カバー７を設けており、この外槽カバー７の下部に、図１３に示すように、洗濯液を散水させる整流部材８を配設している。
【０００４】
上記構成において動作を説明する。洗濯行程では、洗濯兼脱水槽３内に洗濯物（衣類）を入れ、洗濯液の中で洗濯兼脱水槽３を回転させると、この回転力による遠心力で外槽１の内面を洗濯液が競りあがる動きが発生し、上昇した洗濯液は上部の外槽カバー７に配設した整流部材８により方向を変えて、洗濯兼脱水槽３と外槽カバー７の間から洗濯兼脱水槽３内に向けて吐出する。
【０００５】
吐出された洗濯液は洗濯物を通過した後、再び遠心力によって外槽１の内面を競りあがる経路で循環し洗濯を行う。同様にしてすすぎ行程も行われる。このようにして、洗濯、すすぎ、脱水の各行程を自動的に行うことができる。
【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、外槽カバー７の下部に整流部材８を配設しているため、洗濯兼脱水槽３と外槽カバー７との間に所定の隙間が必要となる。また、昨今の洗濯容量の大容量化と洗濯機本体の小型化により、洗濯物が洗濯兼脱水槽３の上端部近傍まで投入され、さらに、洗濯物が脱水行程時の遠心力によって競りあがり、洗濯兼脱水槽３と外槽カバー７の隙間に入り込んで損傷するという問題があった。
【０００７】
また、整流部材８の近傍は洗濯液が吐出するために、洗濯物の侵入を防止する邪魔板などの設置が困難であった。
【０００８】
本発明は上記従来の課題を解決するもので、洗濯性能、すすぎ性能などに影響する整流部材からの洗濯液の吐出の妨害を最小限に押さえながら、整流部材近傍からの洗濯兼脱水槽と外槽カバーとの隙間への洗濯物の入り込みを防止することを第１の目的としている。
【０００９】
また、同様に整流部材近傍部以外においても、洗濯兼脱水槽と外槽カバーとの隙間への洗濯物の入り込みを防止することを第２の目的としている。
【００１０】
また、万一、洗濯物が洗濯兼脱水槽と外槽カバーとの隙間に入り込んだ場合でも、衣類が損傷することなく、洗濯兼脱水槽内へ戻すことを第３の目的としている。
【００１１】
【課題を解決するための手段】
本発明は第１の目的を達成するために、外槽内に回転自在に洗濯兼脱水槽を配設し、外槽の上方を外槽カバーにより覆い、洗濯兼脱水槽を駆動手段によって回転駆動させることによるポンプ作用で洗濯兼脱水槽と外槽の間の洗濯液を洗濯兼脱水槽と外槽カバーの間から洗濯兼脱水槽内に向けて吐出させる構成とし、外槽カバーには、洗濯液を洗濯兼脱水槽の略回転中心に向けて散水する整流部材を設け、洗濯兼脱水槽の回転中心側端部に、洗濯兼脱水槽の回転方向と逆方向へ略垂直に阻止板を配設したものである。
【００１２】
これにより、洗濯性能、すすぎ性能などに影響する整流部材からの洗濯液の吐出の妨害を最小限に押さえながら、整流部材近傍からの洗濯兼脱水槽と外槽カバーとの隙間への洗濯物の入り込みを阻止板によって防止することができる。
【００１３】
また、第２の目的を達成するために、外槽内に回転自在に洗濯兼脱水槽を配設し、外槽の上方を外槽カバーにより覆い、洗濯兼脱水槽を駆動手段によって回転駆動させることによるポンプ作用で洗濯兼脱水槽と外槽の間の洗濯液を洗濯兼脱水槽と外槽カバーの間から洗濯兼脱水槽内に向けて吐出させる構成とし、外槽カバーには、洗濯液を洗濯兼脱水槽の略回転中心に向けて散水する整流部材を設け、整流部材から洗濯兼脱水槽の回転中心側に所定の距離を隔てて略垂直に阻止板を設けたものである。
【００１４】
これにより、洗濯兼脱水槽と外槽カバーとの隙間を覆いかぶせるように阻止板を設けることができ、外槽カバー全周において、洗濯兼脱水槽と外槽カバーとの隙間への洗濯物の入り込みを防止することができる。また、整流部材から所定の距離を隔てているため、比較的洗濯液の吐出状態への影響を少なくすることができる。
【００１５】
また、第３の目的を達成するために、外槽内に回転自在に洗濯兼脱水槽を配設し、外槽の上方を外槽カバーにより覆い、洗濯兼脱水槽を駆動手段によって回転駆動させることによるポンプ作用で洗濯兼脱水槽と外槽の間の洗濯液を洗濯兼脱水槽と外槽カバーの間から洗濯兼脱水槽内に向けて吐出させる構成とし、外槽カバーには、洗濯液を洗濯兼脱水槽の略回転中心に向けて散水する整流部材を設け、洗濯兼脱水槽の回転方向と逆方向に進むにつれて、外槽カバーの外周側へ広がっていく阻止板を少なくとも一つ以上配設したものである。
【００１６】
これにより、万一、洗濯物が洗濯兼脱水槽と外槽カバーとの隙間に入り込んだ場合でも、阻止板に沿って洗濯兼脱水槽の回転中心側へと導かれる。この結果、衣類が損傷することなく、洗濯兼脱水槽内へ戻すことができる。
【００１７】

【００２７】
【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。
【００２８】
（実施例１）
図１および図２に示すように、洗濯機外枠１１は４本の吊り棒１２により外槽１３を防振支持している。洗濯兼脱水槽１４は外槽１３内に回転自在に配設し、洗濯兼脱水槽１４の底部にパルセータ１５を回転自在に配設している。また、洗濯兼脱水槽１４の上部には、液体を内封した液体バランサー１６を固定し、外槽１３の上面は外槽カバー１７によって覆われている。この外槽カバー１７の下面には、水流を整える整流部材１８を配設している。また、モータ（駆動手段）１９は、減速機構２０を介してパルセータ１５または洗濯兼脱水槽１４を駆動する。
【００２９】
ここで、外槽カバー１７には、整流部材１８の洗濯兼脱水槽１４の回転中心側端部に、洗濯兼脱水槽１４の回転方向と逆方向へ、略垂直に阻止板２１を配設している。
【００３０】
上記構成において動作を説明すると、洗濯兼脱水槽１４内に洗濯物を入れ、洗濯液の中で洗濯兼脱水槽１４を回転させると、この回転力による遠心力で外槽１３の内面を洗濯液が競りあがる動きが発生し、上昇した洗濯液は上部の外槽カバー１７に配設した整流部材１８により方向を変えて、洗濯兼脱水槽１４と外槽カバー１７の間から洗濯兼脱水槽１４内に向けて吐出する。吐出された洗濯液は洗濯物を通過した後、再び遠心力によって外槽１３の内面を競りあがる経路で循環し洗濯、すすぎを行う。
【００３１】
つぎに、脱水行程に入るが、ここで、外槽カバー１７の下部に整流部材１８を配設しているため、洗濯兼脱水槽１４と外槽カバー１７との間に所定の隙間が必要となる。そこで、洗濯物が脱水行程時の遠心力によって競りあがり、整流部材１８近傍の洗濯兼脱水槽１４と外槽カバー１７の隙間に入り込んで損傷してしまう場合がある。
【００３２】
このような場合、阻止板２１によって洗濯物の洗濯兼脱水槽１４と外槽カバー１７との隙間への入り込みを阻止することができる。また、吐出流量が多い場合においては、洗濯液の吐出状態への影響も比較的少なく抑えることができる。
【００３３】
（実施例２）
図３に示すように、阻止板２１ａは、外槽カバー１７ａに略垂直に設け、洗濯兼脱水槽１４の回転方向と逆方向の端部に所定角度θの傾斜部２２を設けている。他の構成は上記実施例１と同じである。
【００３４】
上記構成において動作を説明すると、脱水時の遠心力によって競り上がった洗濯物を洗濯兼脱水槽１４と外槽カバー１７ａとの隙間への入り込みを阻止するのは、上記実施例１と同じである。
【００３５】
一方、洗濯兼脱水槽１４の回転方向と逆方向の端部に所定角度θの傾斜部２２を設けているため、万一、洗濯物が洗濯兼脱水槽１４と外槽カバー１７ａの隙間に侵入した場合に、整流部材１８ａへ引っ掛からないようガイドの役割となり、洗濯物の損傷を軽減することができる。また、整流部材１８ａからの洗濯液の吐出状態も傾斜部２２によって整流され、阻止板２１ａの影響を大幅に低減できる。
【００３６】
（実施例３）
図４に示すように、阻止板２１ｂは、外槽カバー１７ｂに略垂直に設け、洗濯兼脱水槽１４の回転中心側の整流部材１８ｂの側壁面との間に隙間２３を設けている。他の構成は上記実施例１と同じである。
【００３７】
上記構成において動作を説明すると、脱水時の遠心力によって競り上がった洗濯物の洗濯兼脱水槽１４と外槽カバー１７ｂとの隙間への入り込みを阻止するのは、上記実施例１と同じである。
【００３８】
一方、洗濯兼脱水槽１４の回転中心側の整流部材１８ｂの側壁面との間に隙間２３を設けているため、吐出量の少ない場合（例えば回転数が低い場合や衣類量が多すぎる場合など）においても、隙間２３から吐出することにより阻止板２１ｂの影響を少なくすることができ、整流部材１８ｂからの洗濯液の吐出状態を良好にできる。
【００３９】
（実施例４）
図５に示すように、阻止板２１ｃは、整流部材１８ｃから洗濯兼脱水槽１４の回転中心側に、液体バランサー１６の内周上端部よりも内側となるよう所定の距離ｄを隔てて、外槽カバー１７ｃに略垂直に設けている。他の構成は上記実施例１と同じである。
【００４０】
上記構成において動作を説明すると、阻止板２１ｃが液体バランサー１６の内周上端部よりも内側となるように構成されているので、洗濯兼脱水槽１４と外槽カバー１７ｃとの隙間を覆いかぶせるように阻止板２１ｃを設けることができ、整流部材１８ｃ近傍だけでなく全周にわたり、洗濯兼脱水槽１４と外槽カバー１７ｃとの隙間への洗濯物の入り込みを一段と困難にすることができる。
【００４１】
さらに、阻止板２１ｃは整流部材１８ｃから所定の距離ｄを隔てているため、阻止板２１ｃによる洗濯液の吐出状態への影響を比較的少なくすることができる。
【００４２】
（実施例５）
図６に示すように、阻止板２１ｄ1、２１ｄ2は、整流部材１８ｄから洗濯兼脱水槽１４の回転中心側に、液体バランサー１６の内周上端部よりも内側となるよう所定の距離ｄ1を隔てて、外槽カバー１７ｄに設けている。他の構成は上記実施例１と同じである。
【００４３】
上記構成において動作を説明すると、脱水時の遠心力によって競り上がった洗濯物を阻止板２１ｄ1で侵入を阻止した後、阻止板２１ｄ2により、脱水の遠心力によりじわじわと再侵入してくる洗濯物に対しても阻止することができる。
【００４４】
なお、本実施例では、２つの阻止板２１ｄ1、２１ｄ2を配設しているが、２つ以上であれば、同様の作用効果を得ることができる。
【００４５】
（実施例６）
図７に示すように、外槽カバー１７ｅに開閉可能な蓋２４を設け、蓋２４に阻止板２１ｅを配設している。他の構成は上記実施例１と同じである。
【００４６】
上記構成において動作を説明すると、阻止板２１ｅを蓋２４に配設しているので、阻止板２１ｅが液体バランサー１６の内周上端部よりも内側となり、洗濯兼脱水槽１４と外槽カバー１７ｅとの隙間を覆いかぶせるように阻止板２１ｅを設けることができ、整流部材１８ｅ近傍だけでなく全周にわたり、洗濯兼脱水槽１４と外槽カバー１７ｅとの隙間への洗濯物の入り込みを一段と困難にすることができる。
【００４７】
さらに、阻止板２１ｅは整流部材１８ｅから所定の距離ｄ2を隔てることになり、阻止板２１ｅによる洗濯液の吐出状態への影響を比較的少なくすることができる。また、洗濯物を入れる時には蓋２４を開けるため、蓋２４に阻止板２１ｅを設けることで、洗濯物を入れる投入口を小さくすることがなくなる。
【００４８】
（実施例７）
図８に示すように、阻止板２１ｆは、外槽カバー１７ｆに設けた固定片２１ｆ1とこの固定片２１ｆ1の先端に可動自在に設けた可動片２１ｆ2とで構成し、可動片２１ｆ2を洗濯兼脱水槽１４の回転中心方向へのみ可動自在としている。他の構成は上記実施例１と同じである。
【００４９】
上記構成において動作を説明すると、可動片２１ｆ2を洗濯兼脱水槽１４の回転中心方向へのみ可動するよう構成することにより、洗濯兼脱水槽１４内からの洗濯物の侵入は阻止し、整流部材１８ｆからの洗濯液の吐出は妨害しないようにすることができ、整流部材１８ｆからの洗濯液の吐出状態へ影響することなく、洗濯兼脱水槽１４と外槽カバー１７ｆとの隙間を覆いかぶせるように阻止板２１ｆを設けることができ、洗濯兼脱水槽１４と外槽カバー１７ｆとの隙間への洗濯物の入り込みを一段と困難にすることができる。
【００５０】
（実施例８）
図９に示すように、阻止板２１ｇは、外槽カバー１７ｇに略垂直に設け、整流部材１８ｇの近傍に開口部２５を設けている。他の構成は上記実施例１と同じである。
【００５１】
上記構成において動作を説明すると、阻止板２１ｇに開口部２５を設けたことにより、容易にかつ低コストで、整流部材１８ｇからの洗濯液の吐出状態へ全く影響することなく、洗濯兼脱水槽１４と外槽カバー１７ｇとの隙間を覆いかぶせるように阻止板２１ｇを設けることができ、洗濯兼脱水槽１４と外槽カバー１７ｇとの隙間への洗濯物の入り込みを困難にすることができる。また、逆に開口部２５の形状を変化させることで、水圧や洗濯液の吐出状態を制御することができる。
【００５２】
（実施例９）
図１０に示すように、外槽カバー１７ｈに、矢印で示す洗濯兼脱水槽１４の回転方向と逆方向に進むにつれて、外槽カバー１７ｈの外周側に広がっていく阻止板２１ｈを、少なくとも１つ以上配設した構成としている。他の構成は上記実施例１と同じである。
【００５３】
上記構成において動作を説明すると、洗濯物の洗濯兼脱水槽１４と外槽カバー１７ｈとの隙間への入り込みを防止しつつ、万一、洗濯物が入り込んだ場合でも、阻止板２１ｈに沿って洗濯兼脱水槽１４の回転中心側へと導かれる。この結果、衣類が損傷することなく、洗濯兼脱水槽１４内へ戻すことができる。
【００５４】
（実施例１０）
図１１に示すように、阻止板２１ｉは、外槽カバー１７ｉに略垂直に設け、弾性体にて構成している。他の構成は上記実施例１と同じである。
【００５５】
上記構成において動作を説明すると、洗濯物の洗濯兼脱水槽１４と外槽カバー１７ｉとの隙間への入り込みの阻止は、他の上記実施例と同じである。万一、高温、多湿などの条件で、衣類アンバランス等により、例えば洗濯兼脱水槽１４が一時的に変形し、阻止板２１ｉと接触したとしても、阻止板２１ｉ０弾性体にて構成しているので、損傷を回避することができる。

The operation in the above configuration will be described. When the laundry is put in the washing / dehydrating tub 14 and the washing / dehydrating tub 14 is rotated in the washing liquid, the inner surface of the outer tub 13 is washed by the centrifugal force generated by the rotational force. The rising washing liquid changes its direction by the rectifying member 18 disposed on the upper outer tub cover 17, and the washing / dehydration tub 14 is interposed between the washing / dehydration tub 14 and the outer tub cover 17. Dispense inward. After the discharged washing liquid passes through the laundry, it is circulated along a path that competes with the inner surface of the outer tub 13 again by centrifugal force to perform washing and rinsing.
