Description

【0001】
【発明の属する技術分野】
本発明は、衣類の洗濯をパルセーターの駆動によって生じる循環水流で行う洗濯機に関する。
【0002】
【従来の技術】
従来、洗濯機はパルセーター式が主流であり、洗濯兼脱水槽に衣類を投入した後、所定量の水と洗剤を投入し、パルセーターを回転させて衣類と水を撹拌し、洗剤を溶解しながら衣類の汚れに作用させるとともに、衣類相互間を摩擦させたり、または衣類と洗濯兼脱水槽の内壁面およびパルセーター表面とを摩擦させて汚れの除去を行っていた。
【0003】
しかし、この方式では洗濯物が傷むという問題や、水や洗剤を多量に使うなどの問題を有していた。発明者らは、これらの課題を解決するために、図5に示すような洗濯機を提案している。以下、その構成について説明する。
【0004】
図に示すように、水受け槽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に吊り下げている。送水路カバー6は、洗濯兼脱水槽3の内面に複数個設けてあり、洗濯兼脱水槽3との間で複数の送水路7を形成している。パルセーター2の裏面には裏羽根8を一体に形成し、裏羽根8の外周にはこれを覆うようにポンプ室9が形成され、複数の送水路7に連通している。
【0005】
複数の送水路7の上部には洗濯兼脱水槽3の内部に向けて開口した散水口10を複数設け、パルセーター2の上方部には多数の孔11を有する仕切り体12を着脱自在に設けている。モータ13は、Vベルト14および減速機構兼クラッチ15を介して、パルセーター2または洗濯兼脱水槽3を駆動する。排水弁16は洗濯兼脱水槽3内の洗濯水を排水し、給水弁17は洗濯兼脱水槽3内に給水するものである。洗濯兼脱水槽3には脱水時の振動を低減させるための流体バランサー18を設け、洗濯兼脱水槽3の上部を蓋19で覆っている。
【0006】
制御装置20は、モータ13、排水弁16、給水弁17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。洗濯物21は、仕切り体12の上に設置されており、パルセーター2と直接接触することはない。
【0007】
上記構成において、制御装置20によりモータ13を駆動してパルセーター2を回転すると、仕切り体12の略中央部に下方に向けての水流22が発生すると同時に、複数の散水口10から滝状に洗濯水23が散水されて洗濯水の循環が行われる。この循環される洗濯水は洗濯物21を通過するためこの循環の繰り返しによって洗濯物21の洗浄が行われる。
【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、洗濯水により衣類をまんべんなく濡らして衣類全面を洗濯水が通過することが要求される。しかし、洗濯する衣類がウールなどのはっ水性の高い繊維からなる場合には、洗濯水が浸透しにくく、そのため、衣類をまんべんなく濡らすことが困難で、循環される洗濯水が衣類の汚れに作用しない場合があり、洗浄性能が悪くなるという問題を有していた。
【0009】
また、洗濯する衣類がウールなどのはっ水性の高い繊維からなる場合には、洗濯水が浸透しにくいため、仕切り体12の上方に浮き上がり、パルセーター2の回転による水流によって仕切り体12の上方で回転し、洗濯兼脱水槽3の内壁面、仕切り体12の上面などに衝突することによる機械力を受け、フェルト化するという問題を有していた。
【0010】
また、粉末洗剤を使用したときは、粉末洗剤の溶け残りが発生しやすいため、溶け残りを含有した洗濯水を循環したとき、仕切り体12上の衣類の上面に残留し、衣類の有効に働く洗剤の量が少なくなり、洗浄性能が悪くなるという問題を有していた。
【0011】
また、洗濯液を滝状に散水して洗浄するため泡立ちやすく、かつ脱水時には衣類にしわや型くずれが生じないように低速脱水を行うので、洗濯兼脱水槽の壁面に付いた泡が脱水回転だけでは除去できないという問題を有していた。
【0012】
本発明は上記課題を解決するもので、ウールなどのはっ水性の高い繊維からなる衣類であっても衣類内部まで洗濯水を安定して浸透させ、循環する洗濯水が衣類の汚れに作用してきれいに洗えるようにすることを第1の目的としている。
【0013】
また、洗濯液を滝状に散水して洗浄することにより発生し洗濯兼脱水槽の壁面に付着した泡をすすぎ行程時の撹拌水流で除去することを第2の目的としている。
【0014】
【課題を解決するための手段】
本発明の洗濯機における第1の手段は、洗濯兼脱水槽の底部にパルセーターを回転自在に配設し、パルセーターの裏羽根の外周にポンプ室を形成し、ポンプ室によって洗濯兼脱水槽内の洗濯水を散水口を設けた送水路を通して洗濯兼脱水槽の上部に送水し、パルセーターの上方を覆うように仕切り体を配設するとともに、設定水位を入力する操作入力手段を備え、給水弁制御手段により、設定水位までの給水途中に水位検知手段が設定水位より低い複数の所定水位を検知した段階で給水弁を一時停止させ、パルセーター制御手段にて所定時間パルセーターを間欠駆動し、この給水開始時から設定水位に給水完了するまでの期間、設定水位変更の入力を禁止するよう構成したものである。
【0015】
これにより、高濃度の洗濯水が衣類の下面から徐々に浸透していくとともに、パルセーターの駆動によって生じる水の振動によって衣類間の空気だまりが排除されるため、ウールなどのはっ水性の高い繊維からなる衣類であっても衣類内部まで洗濯水を浸透させることができ、循環する洗濯水が衣類の汚れに作用し、きれいに洗うことができ、また、使用者が途中で設定水位を変更しようとしても、操作を受け付けて動作を変更することがないため、安定して洗濯水を浸透させることができる。
【0016】
本発明の洗濯機における第2の手段は、洗濯兼脱水槽の底部にパルセーターを回転自在に配設し、パルセーターの裏羽根の外周にポンプ室を形成し、ポンプ室によって洗濯兼脱水槽内の洗濯水を散水口を設けた送水路を通して洗濯兼脱水槽上部に送水し、パルセーター上方部を覆うように仕切り体を配設するとともに、水位検知手段を備え、すすぎ行程で、洗い行程の設定水位より高い所定水位まで給水し、すすぎ運転を行うよう構成したものである。
【0017】
これにより、洗い行程時に発生し洗濯兼脱水槽の壁面に付着した洗濯液の泡をすすぎ行程時の撹拌水流で除去することができる。
【0018】
【発明の実施の形態】
本発明の請求項1に記載の発明は、洗濯兼脱水槽の底部に回転自在に配設したパルセーターと、このパルセーターの裏羽根の外周に形成したポンプ室と、このポンプ室によって洗濯兼脱水槽内の洗濯水を洗濯兼脱水槽上部に送水する送水路と、この送水路に設けた散水口と、前記パルセーターの上方部を覆うように配設した仕切り体と、前記パルセーターの駆動を制御するパルセーター制御手段と、前記洗濯兼脱水槽内に給水する給水弁の開閉を制御する給水弁制御手段と、前記洗濯兼脱水槽内の水位を検知する水位検知手段と、操作入力手段を備え、前記給水弁制御手段は、設定水位までの給水中において前記水位検知手段が設定水位より低い複数の所定水位を検知した段階で給水弁を一時停止させるとともに、前記パルセーター制御手段にて所定時間パルセーターを間欠駆動し、前記操作入力手段は給水開始時から設定水位に給水完了するまでの期間、設定水位変更の入力を禁止するよう構成したものであり、洗濯水は衣類の下部から浸透していくとともに、衣類の間に空気だまりを巻き込むこともないため、ウールなどのはっ水性の高い繊維からなる衣類であっても、衣類内部まで洗濯水を浸透させることができ、循環する洗濯水が衣類の汚れに作用し、きれいに洗うことができ、また、使用者が途中で設定水位を変更しようとしても、操作を受け付けて動作を変更することがないため、安定して洗濯水を浸透させることができる
【0019】
【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。
【0020】
(実施例1)
図1に示すように、制御装置24は、パルセーター2の駆動を制御するパルセーター制御手段25、給水弁17の開閉を制御する給水弁制御手段26、洗濯時間を制御する洗濯時間制御手段27、脱水力を制御する脱水制御手段28を介してモータ13、排水弁16、給水弁17を制御し、洗濯、すすぎ、脱水の各行程を逐次制御する。また、水位検知手段29は洗濯兼脱水槽3内の水位を検知し、検知した情報を制御装置24に入力している。操作入力手段30は洗濯の各種設定等を入力するもので、図2に示すように、水位設定スイッチ30a、スタートスイッチ30b、洗い時間設定スイッチ30c、電源スイッチ30dなどを有し、それぞれの情報を制御装置24に入力している。
【0021】
水位設定スイッチ30aにより、設定される水位によって、(表1)および図3に示すように、1つもしくは複数の所定水位が同時に設定されように構成している。
【0022】
【表1】

Figure 0003787914
【0023】
給水弁制御手段26は、設定水位までの給水途中において、水位検知手段29が所定水位を検知した段階で給水弁17を一時停止させるとともに、パルセーター制御手段25にて所定時間パルセーターを間欠駆動するよう構成している。
【0024】
上記構成において図4を参照しながら動作を説明すると、まず、ステップ31で洗剤を洗濯兼脱水槽3に投入し、ステップ32で仕切り体12を洗濯兼脱水槽3内の所定の位置にセットした後、ステップ33で衣類21を仕切り体12の上部にセットする。つぎに、ステップ34で操作入力手段30に設けた水位設定スイッチ30aにより洗濯水位を設定し、ステップ35でスタートスイッチ30bを押し洗濯を開始する。なお、ここでは、設定水位が(表1)の「低」のように、2つの所定水位を有する場合について述べる。
【0025】
スタートスイッチ30bを押すことにより、ステップ36で制御装置24は給水弁制御手段26に信号を送り、給水弁17をオンにして洗濯兼脱水槽3内に給水する。ステップ37では水位検知手段29により洗濯兼脱水槽3内の水位を検知し、水位設定で設定された第1の所定水位に達したかを判定する。第1の所定水位に達していればステップ38で給水弁17をオフにし、ステップ39で所定時間パルセーター2を間欠駆動し、その後、ステップ40で給水弁17を再度オンにして給水を行う。
【0026】
ステップ41では水位検知手段29により第2の所定水位に達したかを判定する。第2の所定水位に達していればステップ42で給水弁17をオフにし、ステップ43で所定時間パルセーター2を間欠駆動し、その後、ステップ44で給水弁17を再度オンにして給水を行う。つぎに、ステップ45で水位検知手段29により設定水位に達したかを判定する。設定水位に達していればステップ46で給水弁17をオフにし、ステップ47で洗濯を開始する。
【0027】
以上のように、洗濯時の設定水位までに設けた複数の所定水位でパルセーター2を間欠駆動することにより、投入した洗剤と水を撹拌して均一な洗濯水としながら衣類の下部より洗濯水を浸透させることができ、また、間欠駆動による水の動きで衣類間の空気を追い出し、空気だまりが発生するのを防止することができ、循環する洗濯水を衣類にまんべんなく浸透させることができて衣類の汚れに作用し、きれいに洗うことができる。
【0028】
また、設定水位が「少量」や「極少」のように、所定水位が第1の所定水位だけであるときは、図4のステップ39からステップ42までが省略される。
【0029】
そして、ステップ36からステップ46までの期間に、使用者が設定水位を変更しようとした場合、たとえば、ステップ34で設定水位を「少量」にして、ステップ35でスタートした後、ステップ39で設定水位を「低」に切り替えた場合は、ステップ39のパルセーター駆動を中断して給水すると、衣類の下部より順に洗濯水を浸透させる効果が低減するし、水位を切り替えてもステップ39のパルセーター駆動を継続すると、使用者の操作に動作が対応しないため不信感を与える等の問題が発生するため、ステップ35でスタートした後、ステップ46まで、操作入力手段30は、水位設定スイッチ30aの受付けを禁止している。
【0030】
(実施例2)
図1の構成において、給水弁制御手段26は、すすぎ行程で洗い行程の設定水位より高い所定水位まで給水し、すすぎ運転を行うよう構成している。他の構成は上記実施例1と同じである。
【0031】
上記構成において、たとえば、設定水位を「低」に設定して洗濯する場合、図4に示すステップ45で水位検知手段29が洗濯行程の設定水位PS3を検知し、ステップ46にて給水弁制御手段26により給水を完了した後、ステップ47でパルセーター制御手段25によりパルセーター2を回転すると、仕切り体12の略中央部に下方に向けての水流22が発生すると同時に、複数の散水口10から滝状に洗濯水23が散水されて洗濯水の循環が行われる。
【0032】
この循環される洗濯水は洗濯物21を通過するため、この循環の繰り返しによって洗濯物21の洗浄が行われる。このとき、パルセーター2の回転による撹拌水流だけで洗う従来の洗濯方法に比べ、洗濯液が水面に散水されることにより、泡の発生は多くなる。
【0033】
所定時間の洗いを終えた後、制御装置24は排水弁16を駆動して水受け槽1内の洗濯液を排水し、脱水制御手段28にて洗濯兼脱水槽3の回転を制御し脱水する。洗い行程で発生し洗濯兼脱水槽3の壁面に付着した泡は、このときの脱水回転で飛ばされ除去される。しかし、仕切り体12の上に載ったウールなどの衣類21が脱水回転で偏ったり、傷んだりするのを防止するため、このときの脱水力は弱く設定しており、洗剤の種類によっては、泡の発生量が多い、泡の粘度が高いなどにより、泡が十分に除去できない場合がある。
【0034】
つぎに、給水弁制御手段26により、洗い行程時の設定水位PS3より、100mm程度高い所定水位PS5まで給水し、パルセーター制御手段25によりパルセーター2を回転し、すすぎを行う。このとき、前述の脱水行程で残った泡の内、洗濯兼脱水槽3の洗い行程時の水位面より上面に付着した泡も、水没するため、このすすぎの水流により除去することができる。
【0035】
(実施例3)
実施例2と同じ構成において、操作入力手段30で特殊操作を行ったときのみ、すすぎ行程時の水位を上げるように構成している。すなわち、操作入力手段30の水位設定スイッチ30aと洗い時間設定スイッチ30cを同時に押した状態で、電源スイッチ30dを押して電源を入れることにより、特殊モードに設定され、この状態で、さらに水位設定スイッチ30aを複数回押すと、すすぎ時の水位を洗い時より上昇させる設定を行うモードになるようにしている。他の構成は上記実施例1と同じである。
【0036】
上記構成において動作を説明すると、操作入力手段30の水位設定スイッチ30aと洗い時間設定スイッチ30cを同時に押した状態で、電源スイッチ30dを押して電源を入れることにより、サービスマンが洗濯機の点検などをする特殊モードに設定される。この状態で、さらに水位設定スイッチ30aを複数回押すと、すすぎ時の水位を洗い時より上昇させる設定を行うモードになり、ここで設定を行う。この設定により以後は、すすぎ行程の水位を、洗い行程時の設定水位PS3より、100mm程度高い所定水位PS5まで給水し、パルセーター制御手段25によりパルセーター2を回転し、すすぎを行う。
【0037】
したがって、すすぎ行程時の給水において、洗い行程後の脱水で泡が除去できる通常の場合は、給水弁制御手段26により洗い行程時と同じ設定水位PS3まで給水しすすぎを行い、洗い行程後の脱水で泡が除去できない場合は、あらかじめ操作入力手段30で特殊操作を行うことにより、すすぎ行程の水位を洗い行程と変更することができ、洗濯兼脱水槽3の洗い行程時の水位面より上面に付着した泡をすすぎの水流により除去することができる。
【0038】
【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、洗濯兼脱水槽の底部に回転自在に配設したパルセーターと、このパルセーターの裏羽根の外周に形成したポンプ室と、このポンプ室によって洗濯兼脱水槽内の洗濯水を洗濯兼脱水槽上部に送水する送水路と、この送水路に設けた散水口と、前記パルセーターの上方部を覆うように配設した仕切り体と、前記パルセーターの駆動を制御するパルセーター制御手段と、前記洗濯兼脱水槽内に給水する給水弁の開閉を制御する給水弁制御手段と、前記洗濯兼脱水槽内の水位を検知する水位検知手段と、操作入力手段を備え、前記給水弁制御手段は、設定水位までの給水中において前記水位検知手段が設定水位より低い複数の所定水位を検知した段階で給水弁を一時停止させるとともに、前記パルセーター制御手段にて所定時間パルセーターを間欠駆動し、前記操作入力手段は給水開始時から設定水位に給水完了するまでの期間、設定水位変更の入力を禁止するよう構成したから、洗濯水は衣類の下部から浸透していくとともに、衣類の間に空気だまりを巻き込むこともないため、ウールなどのはっ水性の高い繊維からなる衣類であっても、衣類内部まで洗濯水を浸透させることができ、循環する洗濯水が衣類の汚れに作用し、きれいに洗うことができ、また、使用者が途中で設定水位を変更しようとしても、操作を受け付けて動作を変更することがないため、安定して洗濯水を浸透させることができる

BACKGROUND OF THE INVENTION
The present invention relates to a washing machine that performs washing of clothes by a circulating water flow generated by driving a pulsator.
[0002]
[Prior art]
Conventionally, washing machines have been mainly pulsator type, and after putting clothes into the washing and dehydrating tub, add a certain amount of water and detergent, rotate the pulsator to stir the clothes and water, and dissolve the detergent While acting on the dirt of the clothes, the clothes are rubbed with each other, or the clothes and the inner wall surface of the washing and dewatering tank and the pulsator surface are rubbed to remove the dirt.
[0003]
However, this method has a problem that the laundry is damaged and uses a large amount of water and detergent. In order to solve these problems, the inventors have proposed a washing machine as shown in FIG. Hereinafter, the configuration will be described.
[0004]
As shown in the figure, the water receiving tub 1 includes a washing / dehydrating tub 3 in which a pulsator 2 is rotatably disposed at the bottom, and is suspended from a washing machine outer frame 5 by a suspension bar 4. A plurality of water passage covers 6 are provided on the inner surface of the washing and dewatering tub 3, and a plurality of water passages 7 are formed with the washing and dewatering tub 3. A back blade 8 is integrally formed on the back surface of the pulsator 2, and a pump chamber 9 is formed on the outer periphery of the back blade 8 so as to cover the back blade 8, and communicates with a plurality of water supply channels 7.
[0005]
A plurality of water spouts 10 opened toward the inside of the washing and dewatering tub 3 are provided in the upper part of the plurality of water supply channels 7, and a partition body 12 having a large number of holes 11 is detachably provided in the upper part of the pulsator 2. ing. The motor 13 drives the pulsator 2 or the washing and dewatering tub 3 via the V belt 14 and the speed reduction mechanism / clutch 15. The drain valve 16 drains the washing water in the washing / dehydrating tub 3, and the water supply valve 17 supplies water to the washing / dehydrating tub 3. The washing / dehydrating tub 3 is provided with a fluid balancer 18 for reducing vibration during dehydration, and the upper portion of the washing / dehydrating tub 3 is covered with a lid 19.
[0006]
The control device 20 controls the motor 13, the drain valve 16, the water supply valve 17, and the like to sequentially control each process of washing, rinsing, and dehydration. The laundry 21 is installed on the partition 12 and does not come into direct contact with the pulsator 2.
[0007]
In the above configuration, when the pulsator 2 is rotated by driving the motor 13 by the control device 20, a downward water flow 22 is generated at the substantially central portion of the partition 12, and at the same time, a plurality of water spouts 10 form a waterfall. The washing water 23 is sprinkled and the washing water is circulated. Since the circulated washing water passes through the laundry 21, the washing 21 is washed by repeating this circulation.
[0008]
[Problems to be solved by the invention]
In such a conventional configuration, it is required that the clothes are evenly wetted with the wash water and the wash water passes through the entire surface of the clothes. However, if the clothes to be washed are made of highly water-repellent fibers such as wool, it is difficult for the washing water to penetrate, so it is difficult to evenly wet the clothes, and the circulating washing water acts on the dirt on the clothes. In some cases, the cleaning performance deteriorates.
[0009]
In addition, when the clothes to be washed are made of highly water-repellent fibers such as wool, the washing water is difficult to permeate, so that it floats above the partition 12 and is moved upward by the water flow caused by the rotation of the pulsator 2. , And the mechanical force caused by the collision with the inner wall surface of the washing and dewatering tub 3 and the upper surface of the partitioning body 12 causes a problem of felting.
[0010]
In addition, when powder detergent is used, undissolved residue of the powder detergent is likely to occur. Therefore, when washing water containing undissolved residue is circulated, it remains on the upper surface of the clothing on the partition 12 and works effectively. There was a problem that the amount of the detergent was reduced and the cleaning performance was deteriorated.
[0011]
In addition, it is easy to foam because the washing liquid is sprinkled and washed in a waterfall shape, and at the time of dehydration, low-speed dehydration is performed so that wrinkles and deformation of the clothes do not occur. However, it has a problem that it cannot be removed.
[0012]
The present invention solves the above-mentioned problems, and even in clothing made of highly water-repellent fibers such as wool, washing water is stably permeated into the clothing, and the circulating washing water acts on clothing stains. The first purpose is to make it clean and washable.
[0013]
Another object of the present invention is to remove the foam generated by spraying the washing liquid in a waterfall shape and adhering to the wall surface of the washing and dewatering tank with a stirring water flow during the rinsing process.
[0014]
[Means for Solving the Problems]
The first means in the washing machine of the present invention is such that a pulsator is rotatably disposed at the bottom of the washing / dehydrating tub, a pump chamber is formed on the outer periphery of the back blade of the pulsator, and the washing / dehydrating tub is formed by the pump chamber. The inside of the washing water is fed to the upper part of the washing and dewatering tank through the water channel provided with the water spout, and the partition body is disposed so as to cover the top of the pulsator, and the operation input means for inputting the set water level is provided. The water supply valve control means temporarily stops the water supply valve when the water level detection means detects a plurality of predetermined water levels lower than the set water level during water supply to the set water level, and the pulsator control means intermittently drives the pulsator for a predetermined time The input of the set water level change is prohibited during the period from the start of the water supply to the completion of the water supply to the set water level.
[0015]
As a result, high-concentration washing water gradually permeates from the lower surface of the garment, and air stagnation between the garments is eliminated by the vibration of water generated by the driving of the pulsator. Washing water can penetrate into the clothing even if it is made of fiber, the circulating washing water acts on the dirt on the clothing and can be washed cleanly, and the user should change the set water level on the way Even so, since the operation is not changed by changing the operation, the washing water can be stably infiltrated.
[0016]
The second means in the washing machine of the present invention is such that a pulsator is rotatably disposed at the bottom of the washing and dewatering tank, a pump chamber is formed on the outer periphery of the back blade of the pulsator, and the washing and dewatering tank is formed by the pump chamber. The washing water inside is fed to the upper part of the washing and dewatering tank through a water supply channel provided with a water spout, and a partition body is disposed so as to cover the upper part of the pulsator and equipped with a water level detection means, and a washing process is performed in the rinsing process. The water is supplied to a predetermined water level higher than the set water level, and the rinsing operation is performed.
[0017]
Thereby, the foam of the washing | cleaning liquid which generate | occur | produced at the time of a washing process and adhered to the wall surface of a washing and dehydration tank can be removed with the stirring water flow at the time of a rinsing process.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
According to the first aspect of the present invention, there is provided a pulsator rotatably disposed at the bottom of the washing and dewatering tub, a pump chamber formed on the outer periphery of the back blade of the pulsator, and the washing and dehydration by the pump chamber. A water supply path for supplying the washing water in the dehydration tank to the upper part of the washing and dehydration tank, a water spray port provided in the water supply path, a partition disposed so as to cover an upper part of the pulsator, and the pulsator Pulsator control means for controlling driving, water supply valve control means for controlling opening / closing of a water supply valve for supplying water into the washing / dehydrating tub, water level detecting means for detecting the water level in the washing / dehydrating tub, and operation input The water supply valve control means temporarily stops the water supply valve when the water level detection means detects a plurality of predetermined water levels lower than the set water level during water supply up to a set water level, and the pulsator control means The pulsator is intermittently driven for a predetermined time, and the operation input means is configured to prohibit the input of the set water level change from the start of water supply to the completion of water supply to the set water level. Since it does not get trapped in the air between clothes, even clothes made of highly water-repellent fibers such as wool can infiltrate the wash water into the clothes and circulate. The washing water that acts on the dirt on the clothes can be washed cleanly, and even if the user tries to change the set water level in the middle, the operation is not accepted and the operation is not changed, so the washing water is stable Can penetrate .

The motor 13, the drain valve 16 and the water supply valve 17 are controlled via the dehydration control means 28 for controlling the dehydration force, and the respective steps of washing, rinsing and dehydration are sequentially controlled. Further, the water level detection means 29 detects the water level in the washing and dewatering tub 3 and inputs the detected information to the control device 24. As shown in FIG. 2, the operation input means 30 inputs various settings for washing and has a water level setting switch 30a, a start switch 30b, a washing time setting switch 30c, a power switch 30d, and the like. Input to the control device 24.
[0021]
According to the water level set by the water level setting switch 30a, as shown in Table 1 and FIG. 3, one or a plurality of predetermined water levels are set simultaneously.
[0022]
[Table 1]
Figure 0003787914
[0023]
During the water supply up to the set water level, the water supply valve control means 26 temporarily stops the water supply valve 17 when the water level detection means 29 detects the predetermined water level, and the pulsator control means 25 intermittently drives the pulsator for a predetermined time. It is configured to do.
[0024]
The operation will be described with reference to FIG. 4 in the above configuration. First, at step 31, the detergent is put into the washing / dehydrating tub 3, and the partition 12 is set at a predetermined position in the washing / dehydrating tub 3 at step 32. Thereafter, in step 33, the garment 21 is set on the partition 12. Next, in step 34, the washing water level is set by the water level setting switch 30a provided in the operation input means 30, and in step 35, the start switch 30b is pressed to start washing. Here, a case where the set water level has two predetermined water levels, such as “low” in (Table 1), will be described.
[0025]
By pressing the start switch 30b, the control device 24 sends a signal to the water supply valve control means 26 in step 36 to turn on the water supply valve 17 and supply water into the washing and dewatering tub 3. In step 37, the water level detection means 29 detects the water level in the washing and dewatering tub 3 to determine whether the first predetermined water level set by the water level setting has been reached. If the first predetermined water level has been reached, the water supply valve 17 is turned off in step 38, the pulsator 2 is intermittently driven for a predetermined time in step 39, and then the water supply valve 17 is turned on again in step 40 to supply water.
[0026]
In step 41, the water level detection means 29 determines whether the second predetermined water level has been reached. If the second predetermined water level has been reached, the water supply valve 17 is turned off in step 42, the pulsator 2 is intermittently driven for a predetermined time in step 43, and then the water supply valve 17 is turned on again in step 44 to supply water. Next, in step 45, the water level detection means 29 determines whether the set water level has been reached. If the set water level has been reached, the water supply valve 17 is turned off at step 46, and washing is started at step 47.
[0027]
As described above, the pulsator 2 is intermittently driven at a plurality of predetermined water levels provided up to the set water level at the time of washing, so that the washing water can be washed from the lower part of the clothing while stirring the detergent and water to make uniform washing water. In addition, the air between clothes can be expelled by the movement of water due to intermittent drive, and air accumulation can be prevented, and the washing water circulating can be evenly infiltrated into the clothes. Acts on dirt on clothes and can be washed cleanly.
[0028]
Further, when the predetermined water level is only the first predetermined water level, such as “low amount” or “very low”, the steps 39 to 42 in FIG. 4 are omitted.
[0029]
In the period from step 36 to step 46, when the user tries to change the set water level, for example, the set water level is set to “small amount” in step 34, and after starting in step 35, the set water level is set in step 39. Is switched to “low”, if the pulsator driving in step 39 is interrupted and water is supplied, the effect of infiltrating the washing water in order from the bottom of the clothing is reduced, and the pulsator driving in step 39 is performed even if the water level is switched. If the operation continues, the operation does not correspond to the user's operation and causes problems such as distrust. Therefore, after starting at step 35, the operation input means 30 accepts the water level setting switch 30a until step 46. It is prohibited.
[0030]
(Example 2)
In the configuration of FIG. 1, the water supply valve control means 26 is configured to supply water to a predetermined water level higher than the set water level of the washing process in the rinsing process, and perform the rinsing operation. Other configurations are the same as those of the first embodiment.
[0031]
In the above configuration, for example, when washing is performed with the set water level set to “low”, the water level detecting means 29 detects the set water level PS3 of the washing process in step 45 shown in FIG. When the pulsator 2 is rotated by the pulsator control means 25 in step 47 after the water supply is completed at 26, a downward water flow 22 is generated at the substantially central portion of the partition 12, and at the same time, from the plurality of water spray ports 10. The washing water 23 is sprinkled in a waterfall shape and the washing water is circulated.
[0032]
Since the circulated washing water passes through the laundry 21, the washing 21 is washed by repeating this circulation. At this time, compared with the conventional washing method which wash | cleans only with the stirring water flow by rotation of the pulsator 2, the generation | occurrence | production of foam increases by spraying a washing liquid on the water surface.
[0033]
After finishing the washing for a predetermined time, the control device 24 drives the drain valve 16 to drain the washing liquid in the water receiving tub 1, and the dehydration control means 28 controls the rotation of the washing / dehydrating tub 3 to dehydrate. . Foam generated in the washing process and adhering to the wall surface of the washing and dewatering tank 3 is blown off and removed by the dehydration rotation at this time. However, in order to prevent the clothes 21 such as wool placed on the partition body 12 from being biased or damaged due to the dehydration rotation, the dehydration power at this time is set to be weak. In some cases, the foam cannot be sufficiently removed due to a large amount of generation of bubbles or a high viscosity of the foam.
[0034]
Next, the water supply valve control means 26 supplies water to a predetermined water level PS5 that is about 100 mm higher than the set water level PS3 during the washing process, and the pulsator control means 25 rotates the pulsator 2 to perform rinsing. At this time, among the bubbles remaining in the above-described dehydration process, the bubbles adhering to the upper surface from the water level surface during the washing process of the washing and dewatering tank 3 are also submerged and can be removed by this rinsing water flow.
[0035]
Example 3
In the same configuration as that of the second embodiment, the water level during the rinsing process is raised only when a special operation is performed by the operation input means 30. That is, in the state where the water level setting switch 30a and the washing time setting switch 30c of the operation input means 30 are pressed at the same time, the power mode is set by pressing the power switch 30d, and in this state, the water level setting switch 30a is further set. When is pressed several times, the mode is set so that the water level at the time of rinsing is set higher than at the time of washing. Other configurations are the same as those of the first embodiment.
[0036]
The operation in the above configuration will be described. When the water level setting switch 30a and the washing time setting switch 30c of the operation input means 30 are pressed at the same time, the service person checks the washing machine by pressing the power switch 30d to turn on the power. Is set to the special mode. In this state, when the water level setting switch 30a is further pressed a plurality of times, a mode for setting the water level at the time of rinsing to be higher than that at the time of washing is set, and the setting is performed here. After this setting, the water level in the rinsing process is supplied to a predetermined water level PS5 that is about 100 mm higher than the set water level PS3 in the washing process, and the pulsator 2 is rotated by the pulsator control means 25 to perform rinsing.
[0037]
Therefore, in the normal case where bubbles can be removed by dewatering after the washing process in the water supply during the rinsing process, the water supply valve control means 26 supplies and rinses water to the same set water level PS3 as in the washing process, and then dewaters after the washing process. If the foam cannot be removed by the operation input means 30 in advance, the water level in the rinsing process can be changed to the washing process, and the water level surface during the washing process of the washing and dewatering tub 3 can be changed to the upper surface. Adhering foam can be removed by rinsing water flow.
[0038]
