【発明の属する技術分野】
本発明は、洗剤泡の作用によって汚れの除去を効率的に行う洗濯機に関する。
【0002】
【従来の技術】
従来、代表的な洗濯機は、パルセータと呼ばれる撹拌翼を回転させて洗濯するものであり、この種の洗濯機の構成を図9を参照しながら説明する。
【0003】
図9に示すように、外槽1は、底部にパルセ−タ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。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、パルセ−タ2または洗濯兼脱水槽3を駆動する。排水弁9は洗濯兼脱水槽3内の洗濯液を排水し、給水弁10は洗濯兼脱水槽3内に給水するものである。
【0004】
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11を設け、洗濯兼脱水槽3の上部には蓋12を配設している。制御装置13は、モータ6、排水弁9、給水弁10などを制御して、洗濯、すすぎ、脱水の一連の行程を逐次制御するものである。
【0005】
上記構成において動作を説明すると、洗濯兼脱水槽3に洗濯物と所定量の洗剤を投入した後、運転を開始すると制御装置13により給水弁10を制御して洗濯兼脱水槽3内に所定量の水を給水し、その後制御装置13により、モータ6を制御してパルセ−タ2を駆動する。パルセ−タ2の回転によって洗濯兼脱水槽3内の洗濯物と水とを撹拌し、この撹拌によって洗剤を徐々に溶解して洗濯液となり、洗濯物の汚れに作用することとなる。
【0006】
【発明が解決しようとする課題】
しかしながら、この構成の洗濯機の場合、パルセ−タ2の回転によって洗濯兼脱水槽3内の洗濯物を撹拌するといった機械力のみによって洗浄力を確保しているため、洗濯兼脱水槽3の底部にある洗濯物には機械力が伝わりやすいため、高い洗浄力が得られるが、逆に洗濯兼脱水槽3の上部にある洗濯物には機械力が伝わりにくいため、洗浄力が得られず、洗いむらが大きくなるといった問題を有していた。
【0007】
本発明は上記課題を解決するもので、溶解した洗濯液を洗剤泡にして洗濯兼脱水槽内の洗濯物に上方からかけることで、洗浄力を確保し、洗いむらを低減することを目的としている。
【0008】
【課題を解決するための手段】
上記目的を達成するために本発明は、洗濯兼脱水槽の中央内底部にパルセータを回転自在に配設し、洗濯兼脱水槽を内包する外槽の上部開口部にカバー体を取り付け、洗濯兼脱水槽および撹拌翼を回転駆動するモータと、洗濯兼脱水槽内に給水する給水弁と、洗剤泡を発生させるための発泡体と、ホースを介して発泡体と連通するエアポンプと、モータ、給水弁およびエアポンプなどの動作を制御し、洗濯、すすぎ、脱水などの一連の行程を逐次制御する制御手段とを備え、外槽には、洗濯兼脱水槽との間に配し隔により一部を仕切って縦方向に長く上下端部に開口部を有する泡用通路を形成し、泡用通路の上端部の開口部は、カバー体に設けられ洗濯兼脱水槽の内方向に開口した泡吐出部と連通し、泡用通路の下端部の開口部は、外槽の内底部と連通し、発泡体は、泡用通路の内部に設られ、隔壁は、外槽に着脱自在に装着したものである。
【0009】
これにより、溶解した洗濯液を洗剤泡にして洗濯兼脱水槽内の洗濯物に上方からかけることにより、洗濯兼脱水槽の上にある洗濯物の汚れに作用させることができるため、洗浄力を確保し、洗いむらを低減することができるとともに、隔壁は、外槽に着脱自在に装着しているから、組立性に優れ、安価に洗浄力を高め、洗いむらを少なくすることができる
【0010】
【発明の実施の形態】
本発明の請求項1に記載の発明は、中央内底部にパルセータを回転自在に配設した洗濯兼脱水槽と、前記洗濯兼脱水槽を内包する外槽と、前記外槽の上部開口部に取り付けたカバー体と、前記洗濯兼脱水槽および撹拌翼を回転駆動するモータと、前記洗濯兼脱水槽内に給水する給水弁と、洗剤泡を発生させるための発泡体と、ホースを介して前記発泡体と連通するエアポンプと、前記モータ、給水弁およびエアポンプなどの動作を制御し、洗濯、すすぎ、脱水などの一連の行程を逐次制御する制御手段とを備え、前記外槽には、洗濯兼脱水槽との間に配置し隔壁により一部を仕切って縦方向に長く上下端部に開口部を有する泡用通路を形成し、前記泡用通路の上端部の開口部は、前記カバー体に設けられ前記洗濯兼脱水槽の内方向に開口した泡吐出部と連通し、前記泡用通路の下端部の開口部は、前記外槽の内底部と連通し、前記発泡体は、前記泡用通路の内部に設けられ、前記隔壁は、前記外槽に着脱自在に装着したものであり、溶解した洗濯液を泡発生機構部により洗剤泡にして、この洗剤泡を外槽と隔壁とこの隔壁の上下端部に設けた開口部とにより形成される泡用通路より洗濯兼脱水槽内の洗濯物に上方からかけることで、洗浄力を確保できて、洗いむらを低減することができるとともに、隔壁は、外槽に着脱自在に装着したものであり、組立性に優れ、安価に洗浄力を高め、洗いむらを少なくすることができる。
【0011】
請求項に記載の発明は、上記請求項1記載の発明において、隔壁は、上方から下方にスライドして挿入することで両側面を外槽に係止した後、上端部をカバ−体で押えて固定したものであり、より組立性に優れ、安価に洗浄力を高め、洗いむらを少なくすることができる。
【0012】
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、発泡体は、隔壁の泡用通路側面に設けた保持リブにより保持されるようにしたものであり、発泡体の取り付けがきわめて簡単な構成にでき、組立性に優れ安価に上から洗剤泡をかけて洗濯することができ、たくさんの洗剤成分を洗濯兼脱水槽内の洗濯物の汚れに作用させることができるため、洗浄力を高めることができる。
【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。
【0014】
(実施例1)
図1に示すように、外槽14は、回転自在に配設した洗濯兼脱水槽15を内包し、吊り棒16により洗濯機外枠17に吊り下げている。モータ18は、Vベルト19および減速機構20を介して洗濯兼脱水槽15および洗濯兼脱水槽15の内底部に回転自在に配設したパルセ−タ21を回転駆動する。
【0015】
カバー体22は、外槽14の上部開口部23に設け、泡吐出部24を形成するものであり、泡吐出部24は、洗濯兼脱水槽15内に向けて開口している。隔壁25は外槽14の一部を仕切って縦方向に長い、上下端部に開口部27を有する泡用通路26を形成している。この泡用通路26の下端の開口部27を外槽14の内底部と連通させ、泡用通路26の上端の開口部27は、泡吐出部24に連通している。泡用通路26内に発泡体28からなる泡発生機構部29を設け、この泡発生機構部29は、ホース30を介してエアポンプ31と連通している。
【0016】
発泡体28は、図2に示すように、略円筒形状をしており、両平面側の内部にそれぞれ第1の保持部32と第2の保持部33を挿入している。第1の保持部32は中空としており、発泡体28内部に挿入されていない端部は、ホース30に挿入されている。
【0017】
給水弁34は、洗濯兼脱水槽15内に水を給水するものであり、排水弁35は外槽14内の洗濯液を排水するものである。
【0018】
制御装置36は、図3に示すように構成しており、制御手段37は、マイクロコンピュータで構成し、パワースイッチング手段38を介してモータ18、エアポンプ31、給水弁34、排水弁35などの動作を制御し、洗濯、すすぎ、脱水などの一連の行程を逐次制御する。入力設定手段39は、運転コース等を設定するもので、制御手段37は入力設定手段39からの情報を入力して、その情報を基に表示手段40で表示して使用者に知らせる。記憶手段41は、制御手段37により制御するのに必要なデータを記憶している。なお、42は商用電源、43は電源スイッチである。
【0019】
上記構成において動作を説明すると、洗濯兼脱水槽15内に洗濯物と洗剤を投入した後、運転を開始すると、制御手段37は、給水弁34を作動させて給水を開始し、同時に、洗濯兼脱水槽15が回転を始める。洗濯兼脱水槽15内の水位が設定水位に達するまでの間、洗濯兼脱水槽15は回転する。このように洗濯兼脱水槽15を回転しながら給水を行った場合、洗濯兼脱水槽15の回転によって生じる撹拌力によって、投入された洗剤が溶解する。
【0020】
設定水位に達した時点で給水弁34の動作を停止し、洗濯兼脱水槽15の回転は継続する。制御手段37によってエアポンプ31が作動して、泡用通路26内に設け隔壁25の下端に設けた開口部27により侵入した洗濯液中の発泡体28にホース30、第1の保持部32を通して空気が送られる。
【0021】
この結果、図1に示すように、発泡体28に送られた空気は、発泡体28から出るときに気泡となって上昇し、洗濯液面に達して洗剤泡が発生する。洗剤泡は外槽14と隔壁25とにより形成される泡用通路26を通って上昇し、この泡用通路26の上端の開口部27と連通するカバー体22の泡吐出部24から洗濯兼脱水槽15内の洗濯物にかけられる。
【0022】
このようにして、洗剤泡を汚れた衣類の表面あるいは衣類を通過させることによって、泡に油および油に付着した粒子汚れが結合して持ち去ることになる。また、泡が衣類通過中に破泡すると、衣類に高濃度の洗剤液がしみ込むことになり、これによっても汚れが落ちやすい状態となる。このようにして衣類の洗浄が可能となる。
【0023】
このことにより、洗濯液を泡にすることで、泡を汚れた洗濯物の表面あるいは洗濯物を通過させることによって、油および油に付着した粒子汚れを結合して持ち去ることや、泡が洗濯物通過中に破泡すると洗濯物に高濃度の洗剤液がしみ込むことが可能となり、洗浄力を高めることができる。また、洗濯液を泡にすることにより、体積が増えるため、少ない洗濯液で洗濯物の汚れに洗剤成分を作用させることができるとともに、洗剤泡を上方よりかけることにより、洗濯兼脱水槽15の上にある機械力が伝わりにくい洗濯物の汚れに作用させることができるため、洗いむらを低減することができる。
【0024】
(実施例2)
図4および図5に示すように、隔壁44は外槽45と別体で、ねじ52により固定することにより着脱自在に形成しており、この隔壁44には、隔壁44に一体に設けた保持リブ46に発泡体47を第1の保持部48および第2の保持部49を介して保持するとともに、隔壁44に一体に複数個設けた爪部50にホ−ス51を保持している。他の構成は上記実施例1と同じである。
【0025】
上記構成において動作を説明すると、隔壁44は外槽45と別体で着脱自在に形成されているため、外槽45の製作が容易にできる。
【0026】
また、この隔壁44には、発泡体47とホ−ス51を保持しているため、発泡体47やホース51の取り付けがきわめて簡単な構成にでき、組立性に優れ安価に上から洗剤泡をかけて洗濯することができ、たくさんの洗剤成分を洗濯兼脱水槽15内の洗濯物の汚れに作用させることができるため、洗浄力を高めることができる。
【0027】
(実施例3)
図6から図8に示すように、隔壁70は、外槽71と別体で着脱自在で、両側面に略コ字状に凹部72を形成し、外槽71に設けた凸部73に上方より下方へスライドして挿入し、その後、カバー体74を外槽71に取り付け、隔壁70の上端をカバー体74で押さえて固定している。この状態で、隔壁70の上端はカバー体74の下面に当接し、隔壁70の下端は外槽71と当接している。他の構成は上記実施例1と同じである。
【0028】
上記構成において動作を説明すると、隔壁70は、外槽71と別体で着脱自在で、両側面に略コ字状に凹部72を形成し、外槽71に設けた凸部73に係止しているため、外槽71と隔壁70の両側面の放射方向の固定がなされ、また、泡漏れを防止できる。
【0029】
また、隔壁70の上端はカバー体74の下面に当接し、隔壁70の下端は外槽71と当接しているため、外槽71と隔壁70の上下方向の固定をすることができ、前述の両側面と合わせて、きわめて簡単な構成で隔壁70のがたを防止することができ、異常音の防止ができるとともに、安価に上から洗剤泡をかけて洗濯することができ、たくさんの洗剤成分を洗濯兼脱水槽15内の洗濯物の汚れに作用させることができるため、洗浄力を高めることができる。

[0013]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
Example 1
As shown in FIG. 1, the outer tub 14 encloses a washing and dewatering tub 15 that is rotatably arranged, and is suspended from a washing machine outer frame 17 by a suspension bar 16. The motor 18 rotationally drives the washing / dehydrating tub 15 and the pulsator 21 rotatably disposed on the inner bottom of the washing / dehydrating tub 15 via the V-belt 19 and the speed reduction mechanism 20.
[0015]
The cover body 22 is provided in the upper opening 23 of the outer tub 14 to form a foam discharge part 24, and the foam discharge part 24 opens toward the washing and dehydration tank 15. The partition wall 25 divides a part of the outer tub 14 and forms a foam passage 26 that is long in the vertical direction and has openings 27 at upper and lower ends. The opening 27 at the lower end of the foam passage 26 is communicated with the inner bottom of the outer tub 14, and the opening 27 at the upper end of the foam passage 26 is communicated with the foam discharge section 24. A foam generation mechanism 29 made of a foam 28 is provided in the foam passage 26, and the foam generation mechanism 29 communicates with the air pump 31 via a hose 30.
[0016]
As shown in FIG. 2, the foam 28 has a substantially cylindrical shape, and a first holding portion 32 and a second holding portion 33 are inserted into the insides of both planes. The first holding portion 32 is hollow, and the end portion that is not inserted into the foam 28 is inserted into the hose 30.
[0017]
The water supply valve 34 supplies water into the washing / dehydrating tub 15, and the drain valve 35 drains the washing liquid in the outer tub 14.
[0018]
The control device 36 is configured as shown in FIG. 3, and the control means 37 is constituted by a microcomputer, and the operation of the motor 18, the air pump 31, the water supply valve 34, the drain valve 35, etc. via the power switching means 38. And a series of processes such as washing, rinsing and dehydration are sequentially controlled. The input setting means 39 sets the driving course and the like, and the control means 37 inputs information from the input setting means 39 and displays it on the display means 40 based on the information to notify the user. The storage means 41 stores data necessary for control by the control means 37. Reference numeral 42 denotes a commercial power source and 43 denotes a power switch.
[0019]
The operation in the above configuration will be described. When the operation is started after the laundry and the detergent are put into the washing and dewatering tub 15, the control means 37 operates the water supply valve 34 to start the water supply. The dewatering tank 15 starts to rotate. The washing and dewatering tank 15 rotates until the water level in the washing and dewatering tank 15 reaches the set water level. When water is supplied while rotating the washing / dehydrating tub 15 as described above, the introduced detergent is dissolved by the stirring force generated by the rotation of the washing / dehydrating tub 15.
[0020]
When the set water level is reached, the operation of the water supply valve 34 is stopped, and the rotation of the washing and dewatering tub 15 is continued. The air pump 31 is actuated by the control means 37, and the air is passed through the hose 30 and the first holding part 32 to the foam 28 in the washing liquid which has entered through the opening 27 provided in the foam passage 26 and provided at the lower end of the partition wall 25. Will be sent.
[0021]
As a result, as shown in FIG. 1, the air sent to the foam 28 rises as bubbles when it leaves the foam 28, reaches the washing liquid surface, and detergent bubbles are generated. The detergent foam rises through the foam passage 26 formed by the outer tub 14 and the partition wall 25, and is washed and removed from the foam discharge portion 24 of the cover body 22 communicating with the opening 27 at the upper end of the foam passage 26. It is put on the laundry in the water tank 15.
[0022]
In this way, by passing the detergent foam through the soiled garment surface or the garment, the foam and the particulate soil adhering to the oil are bound and carried away. Further, when the foam breaks while passing through the clothes, a high-concentration detergent solution is soaked into the clothes, and this also makes it easy to remove dirt. In this way, the clothes can be washed.
[0023]
As a result, the washing liquid is made into foam, and the foam is allowed to pass through the surface of the laundry or the laundry, so that the oil and the particle dirt adhered to the oil can be combined and carried away, or the foam can be washed away. If bubbles are broken during the passage, it becomes possible for a detergent solution of high concentration to penetrate into the laundry, and the cleaning power can be increased. Moreover, since the volume is increased by making the washing liquid into foam, the detergent component can be made to act on the dirt of the laundry with a small amount of washing liquid. Uneven washing can be reduced because it can act on the soil of the laundry where the mechanical force on it is difficult to be transmitted.
