Description

【0001】
【発明の属する技術分野】
本発明は、泡発生装置及び泡発生機能付き洗濯機に関するものである。
【0002】
【従来の技術】
従来、洗濯機用などの泡発生装置としては、図16に示すように、槽100内に溜めた洗い水(洗浄水若しくは洗濯水)内に多数の連続通水孔を有する部材(以下、連続通水孔部材と称す)101を沈め、その連続通水孔部材101内にエアーポンプ102で空気を送る込むことによってその連続通水孔部材101から泡104を発生させるとともに、その泡104を、連続通水孔部材101に連結され、かつ、槽100の上部に向って細く伸びる細管103により、槽100の上方から槽100の内底に向って落下させるようにしたものが知られていた。
【0003】
さらに、泡発生機能付き洗濯機としては、洗濯槽の内底に設けたパルセーターの下側に、エアーポンプで空気を送り込んで泡(気泡)を発生させ、その泡を、パルセーターに設けた多数の気泡通過孔から噴出させて洗濯物の表面や洗濯物間に付着させるようにしたものが知られていた(例えば、特許文献1参照)。
【0004】
【特許文献1】
特開平5−200183号公報(3頁右段の31行〜46行)
【0005】
【発明が解決しようとする課題】
上記泡発生装置における槽100内に溜めた洗い水では、槽100に洗剤を投入し、その後、水道水などの水を流入させることによって得るようにしているため、洗剤が均一に溶けた状態になっていない。しかも、洗剤が粉状の場合には、洗剤が水に溶けていないことがある。そのために、連続通水孔部材101から発生した泡は、洗剤が均一に溶けた泡とならないとともに、洗剤が連続通水孔部材101の表面に付着してしまうという問題点があった。しかも、連続通水孔部材101から発生した泡を細管103に集めてその細管103の上端側から槽100の内底に向って落下させるようにしているために、必要量の泡を得るのに、時間がかかってしまうという問題点があった。
【0006】
さらに、上記特開平5−200183号公報の洗濯機では、洗濯槽の高水位まで洗濯水を溜めた状態で、パルセーターに設けた多数の気泡通過孔から泡を噴出させているため、その泡は高濃度の洗剤を含んだ泡ではなく、かつ、大量の泡が生じないため、泡洗浄の効果が十分に得られないという問題点があった。
【0007】
本発明の第一目的は、上記のような問題点に鑑みてなされたもので、高濃度の洗剤を均一に含んだ泡を効率よく大量に作ることのできる泡発生装置を提供することにある。
【0008】
本発明の第二目的は、上記のような問題点に鑑みてなされたもので、高濃度の洗剤を均一に含んでなるきめの細かい泡を効率よく作ることのできる泡発生装置を提供することにある。
【0009】
本発明の第三目的は、上記のような問題点に鑑みてなされたもので、高濃度の洗剤を均一に含んだ泡を効率よく作ることのできる泡発生機能付き洗濯機を提供することにある。
【0010】
本発明の第四目的は、上記のような問題点に鑑みてなされたもので、高濃度の洗剤を均一に含んでなるきめの細かい泡を効率よく作ることのできる泡発生機能付き洗濯機を提供することにある。
【0011】
【課題を解決するための手段】
本発明の第一目的は、少量の水と洗剤を混入させることによって得られる洗い水を溜める槽と、この槽内から吸込まれた前記洗い水に空気を混合させつつその洗い水及び空気を前記槽内に噴出させるポンプ手段を少なくとも備え、前記ポンプ手段を所定時間駆動させて前記洗い水及び空気を前記槽と前記ポンプ手段の間で繰り返し循環させることで、前記洗い水及び空気を繰り返し前記槽内に噴出させて前記槽内に泡を発生させる構成とすることにより、達成できる。
【0012】
この構成によれば、槽内に溜めた洗い水に洗剤が均一に溶けていなくとも、ポンプ手段により洗い水に混入されている洗剤及び空気とが十分に混合されるので、槽内から吸込まれた洗い水が、気泡を含む均一高濃度の洗剤液となってポンプ手段の吐出口側から噴出するため、槽内に、高濃度の洗剤を均一に含んだ泡が発生する。しかも、その気泡を含む均一高濃度の洗剤液が、繰り返し前記槽内に噴出するので、その槽内に、高濃度の洗剤を均一に含んだ泡が短時間に発生する。また、槽内に投入する洗剤が粉状であって固まっていても、ポンプ手段により、その固まった洗剤がポンプ手段により溶かされる。
【0013】
本発明の第二目的は、少量の水と洗剤を混入させることによって得られる洗い水を溜める槽と、この槽内から吸込まれた前記洗い水に空気を混合させつつその洗い水及び空気を前記槽内に噴出させるポンプ手段を少なくとも備え、前記ポンプ手段を所定時間駆動させて前記洗い水及び空気を前記槽と前記ポンプ手段の間で繰り返し循環させることで、前記洗い水及び空気を繰り返し前記槽内に噴出させて前記槽内に泡を発生させるようにした泡発生装置において、前記ポンプ手段を、ギヤポンプと、一端を前記ギヤポンプの入口側に連通させ、かつ、他端を前記槽内に連通させた吸込み通路手段と、前記ギヤポンプの入口側に配設した空気吸入手段と、前記ギヤポンプの出口側に連結した通路切換弁と、一端を前記通路切換弁の一方の出口に連結させ、かつ、他端を前記槽内に連通させた噴出通路手段と、一端を前記通路切換弁の他方の出口に連結させ、かつ、他端に通水抵抗体を設けた泡吐出流路手段から構成し、前記ギヤポンプの出口側と前記泡吐出流路手段が連通した状態となるように前記通路切換弁を切り換えて前記ギヤポンプを駆動させることにより、前記泡及び洗い水が前記通水抵抗体を通り抜けることで前記通水抵抗体の表面から泡を吐出させることによって、達成できる。
【0014】
この構成によれば、ギヤポンプにより、槽内から吸込まれた洗い水を、気泡を含む均一高濃度の洗剤液とし、その気泡を含む均一高濃度の洗剤液が槽内に噴出させられて、槽内に高濃度の洗剤を均一に含んだ泡が短時間で発生する。しかも、槽内に高濃度の洗剤を均一に含んだ泡を必要量、発生させたならば、通路切換弁を切り換えてギヤポンプの出口と泡吐出流路手段とを連通させた状態でギヤポンプを駆動させると、槽内に発生した高濃度の洗剤を均一に含んだ泡及び槽内に残っている洗い水に、さらに空気が混合させられて、気泡を含むより均一高濃度の洗剤液となって、ギヤポンプの出口から噴出する。この噴出した気泡を含むより均一高濃度となった洗剤液を、泡吐出流路手段の他端に設けた通水抵抗体から吐出させることで、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)として、短時間で取り出すことができる。
【0015】
本発明の第三目的は、少量の水と洗剤を混入させることによって得られる洗い水を溜める洗濯槽と、この洗濯槽内から吸込まれた前記洗い水に空気を混合させつつその洗い水及び空気を前記洗濯槽内に噴出させるポンプ手段と、前記洗濯槽内に投入した洗濯物を攪拌させる攪拌手段を少なくとも具備し、前記ポンプ手段を所定時間駆動させて前記洗い水及び空気を前記洗濯槽と前記ポンプ手段の間で繰り返し循環させることで、前記洗い水及び空気を繰り返し前記洗濯槽内に噴出させて前記洗濯槽内に泡を発生させることにより、達成できる。
【0016】
この構成によれば、洗濯槽内に溜めた洗い水に洗剤が均一に溶けていなくても、ポンプ手段により洗い水に混入されている洗剤及び空気が十分に混合されるので、洗濯槽から吸込んだ洗い水が、気泡を含む均一高濃度の洗剤液となってポンプ手段の出口側から噴出するため、洗濯槽内に、高濃度の洗剤を均一に含んだ泡が発生する。しかも、その気泡を含む均一高濃度の洗剤液が、繰り返し前記洗濯槽に噴出するので、その洗濯槽内に、高濃度の洗剤を均一に含んだ泡が短時間に発生する。また、洗濯槽内に投入する洗剤が粉状であって固まっていても、ポンプ手段により、その固まった洗剤がポンプ手段により溶かされる。しかも、その気泡を含む均一高濃度の洗剤液が、ポンプ手段の出口側から洗濯槽内に繰り返し噴出するので、その洗濯槽内に、高濃度の洗剤を均一に含んだ泡が短時間で大量に発生するため、その高濃度の洗剤を均一に含んだ泡で、洗濯槽内に投入した洗濯物全体を短時間に包み込むことができる。
【0017】
本発明の第四目的は、少量の水と洗剤を混入させることによって得られる洗い水を溜める洗濯槽と、この洗濯槽内から吸込まれた前記洗い水に空気を混合させつつその洗い水及び空気を前記洗濯槽内に噴出させるポンプ手段と、前記洗濯槽内に投入した洗濯物を攪拌させる攪拌手段を少なくとも具備し、前記ポンプ手段を所定時間駆動させて前記洗い水及び空気を前記洗濯槽と前記ポンプ手段の間で繰り返し循環させることで、前記洗い水及び空気を繰り返し前記洗濯槽内に噴出させて前記洗濯槽内に泡を発生させるようにした泡発生機能付き洗濯機において、前記ポンプ手段を、ギヤポンプと、一端を前記ギヤポンプの入口側に連通させ、かつ、他端を前記洗濯槽内に連通させた吸込み通路手段と、前記ギヤポンプの入口側に配設した空気吸入手段と、前記ギヤポンプの出口側に連結した通路切換弁と、一端を前記通路切換弁の一方の出口に連結させ、かつ、他端を前記洗濯槽内に連通させた噴出通路手段と、一端を前記通路切換弁の他方の出口に連結させ、かつ、他端に通水抵抗体を設けた泡吐出流路手段から構成し、前記ギヤポンプの出口側と前記泡吐出流路手段が連通した状態となるように前記通路切換弁を切り換えて前記ギヤポンプを駆動させることにより、前記泡及び洗い水が前記通水抵抗体を通り抜けることで前記通水抵抗体の表面から泡を吐出させることによって、達成できる。
【0018】
この構成によれば、ギヤポンプにより、洗濯槽から吸込まれた洗い水を、気泡を含む均一高濃度の洗剤液とし、その洗剤液を洗濯槽内に吐出させることにより短時間で得られた高濃度の洗剤を均一に含んだ泡が、洗濯槽内に投入した洗濯物に浸透させられる。その後、通路切換弁を切り換えてギヤポンプの出口側と泡吐出流路手段とを連通させた状態でギヤポンプを駆動させれば、洗濯槽内に噴出させて短時間で得られた高濃度の洗剤を均一に含んだ泡及び洗濯槽内に残っている洗い水が、その泡及び洗い水にさらに空気が混合させられることで、気泡を含むより均一高濃度の洗剤液となって、ギヤポンプの出口から噴出する。この噴出した気泡を含むより均一高濃度となった洗剤液を、泡吐出流路手段の他端に設けた通水抵抗体から吐出させることで、泡吐出流路手段の他端に設けた通水抵抗体から高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)にし、そのきめの細かい泡(クリーミィな泡)を洗濯槽内の洗濯物上に短時間で落下させることができる。したがって、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)によって、洗濯物全体が短時間に包み込まれるので、その高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)が洗濯物全体に浸透するため、洗濯物の汚れが円滑に取り除かれるようになる。
【0019】
【発明の実施の形態】
以下、本発明の泡発生装置の一実施形態を、図1〜図9に基づいて説明する。図1において、泡発生装置1は、洗い水W1を溜める上端開放の槽2と、この槽2から吸込まれた洗い水W1に空気Zを混合させつつその洗い水W1及び空気Zを槽2に噴出させるためのポンプ手段となるギヤポンプ3と、一端4A側をギヤポンプ3の入口3A側に連通させ、かつ、他端4B側を槽2内に連通させた吸込み通路手段となる吸込みホース4と、ギヤポンプ3の出口3B側に連結された通路切換弁5と、一端6Aを通路切換弁5の一方の出口5Aに連結させ、かつ、他端6Bを槽2内に連通させた噴出通路手段となる噴出通路ホース6と、一端8Aを通路切換弁5の他方の出口5Bに連結させ、かつ、他端8Bに通水抵抗体7を設けた泡吐出流路手段となる吐出通路ホース8を少なくとも備えている。
【0020】
洗い水W1は、例えば、約1リットルの水W0に、市販されている洗剤のうち粉末洗剤の場合には約15グラムの粉末洗剤Sを、また、市販されている洗剤のうち液体洗剤の場合には約50グラムを、それぞれ投入することにより得られる。水W0は、水道水でもよいが、軟水であれば、より好ましい。
【0021】
槽2は、水及び洗剤を投入することができ、かつ投入させた水及び洗剤により得られた洗い水W1を溜めることができものであれば、材質は合成樹脂製でも金属製でもよく、形は円筒でも角筒でもよい。槽2には、その槽2の上端開放部を覆う蓋体2Aを着脱可能に設け、その蓋体2Aに設けた投入口(図示せず)から水及び粉末洗剤若しくは液体洗剤を、槽2内に投入できる構造としてある。
【0022】
ギヤポンプ3は、図2に示すように、合成樹脂からなるモータケーシング9と、耐摩耗性に優れた合成樹脂からなる中間ケーシング10と、耐摩耗性に優れた合成樹脂からなる歯車ポンプケーシング11を有している。中間ケーシング10と歯車ポンプケーシング11とは、水密的に取り付けられている。モータケーシング9には、図2に示すように、モータ12が収納されている。モータケーシング9の開放端面には、合成樹脂からなるカバー9Aが着脱自在に取り付けられている。カバー9Aには、モータ12を電源に電気的に接続するための一対の端子12Aを突出させている。モータ12としては、整流子モータやブラシレスモータなどが採用されている。
【0023】
歯車ポンプケーシング11内には、駆動歯車13及びこの駆動歯車13に噛合うところの従動歯車14が収納されている。歯車ポンプケーシング11の外周壁には、駆動歯車13と従動歯車14の噛合い部分を挟んで対向するように、円筒状の入口3Aと円筒状の出口3Bとが一体成形されている。
【0024】
モータ12の回転は、減速機構15を介して駆動歯車13に伝達されるようにしてある。減速機構15は、モータ12の回転軸12Bに取り付けられた減速用駆動歯車15Aと、この減速用駆動歯車15Aと噛合い、かつ、駆動歯車13の回転軸13Aに取り付けられた減速用従動歯車15Bからなっている。駆動歯車13の回転軸13Aは、図2に示すように、中間ケーシング10を貫通してモータケーシング9側に延在させてある。中間ケーシング10における回転軸13Aの貫通部分には、軸封部材13Bが設けられている。従動歯車14は、歯車ポンプケーシング11の内側壁とこの内側壁と対向する中間ケーシング10の側壁とに固定した固定心棒16に、回転自在に取り付けられている。駆動歯車13及び従動歯車14は、駆動歯車13の回転軸心となる回転軸13Aと従動歯車14の回転軸心となる固定心棒16が平行となるように、歯車ポンプケーシング11内に配置されている。
【0025】
歯車ポンプケーシング11の内壁と駆動歯車13の外周との間のクリアランス及び歯車ポンプケーシング11の内壁と従動歯車14の外周との間のクリアランスは、例えば、0.05mm程度に設定してある。駆動歯車13と従動歯車14は、耐磨耗性に優れた合成樹脂や硬質ゴムなどからなり、同じ大きさのものが用いられる。駆動歯車13及び従動歯車14は、歯数を例えば、16に、最大歯先円直径を例えば、31.505mmに、最大歯底円直径を例えば、23.625mmに、最大厚さを例えば、18.425mmに、それぞれ設定されている。減速機構15の減速用駆動歯車15A及び減速用従動歯車15Bの、歯数、最大歯先円直径及び最大歯底円直径は、モータ12の高速回転を減速させて駆動歯車13及び従動歯車14の回転数が約2500回/分以上となるように、設定されている。
【0026】
吸込みホース4は、可撓性の管体からなり、図1などに示すように、一端4Aが気水混合部材17を介してギヤポンプ3の入口3Aに連通され、かつ、他端4Bが槽2に溜まる水に没するように設置されている。吸込みホース4の他端4Bには、ストレーナー18が設けられている。ストレーナー18は、槽2内に溜めた洗い水W1に混入した髪の毛、衣類片、紙片などの比較的大きな粗塵が吸込みホース4内に流入するのを阻止するものである。なお、槽2内に溜めた洗い水W1に粗塵が含まれていない場合には、吸込みホース4の他端4Bにストレーナー18を設けなくともよい。
【0027】
空気吸入手段となる気水混合部材17は、図3〜図5に示すように、筒体本体17Aと、この筒体本体17Aに設けた吸気口17A‐1に設けられたダックビル方式などの空気補給弁17Bとからなっている。筒体本体17Aの一端は、吸込みホース4の一端4Aに水密的に取り付けられる。筒体本体17Aの他端は、ギヤポンプ3の入口3Aに水密的に取り付けられる。吸込みホース4の一端4Aと筒体本体17Aの一端との取り付け及びギヤポンプ3の入口3Aと筒体本体17Aの他端との取り付けは、接着剤で固定するようにしてもよいし、ホースバンドやクリップ止めを用いて取り外し可能に取り付けるようにしてもよい。
【0028】
筒体本体17Aの吸気口17A‐1に設けた空気補給弁17Bは、ギヤポンプ3が作動して筒体本体17Aを槽2から吸込まれた洗い水W1がギヤポンプ3に向って流れている状態(ギヤポンプ運転状態)になると、図4に示すように、開いて筒体本体17A外方の空気Zを筒体本体17A内に取り込み、しかも、ギヤポンプ3が停止して筒体本体17Aを槽2から吸込まれた洗い水W1が流れない状態(ギヤポンプ停止状態)になると、図5に示すように、閉じて筒体本体17A外方の空気Zが筒体本体17A内に取り込まれなくなるという機能を有している。
【0029】
ギヤポンプ3と通路切換弁5は、図1などに示すように、連結管19により連結されている。すなわち、連結管19の一端をギヤポンプ3の出口3Bに水密的に取り付け、かつ、連結管19の他端を通路切換弁5の入口5Cに水密的に取り付けることで、ギヤポンプ3の出口3Bと通路切換弁5の入口5Cとが連結される。連結管19の一端とギヤポンプ3の出口3Bとの取り付け及び連結管19の他端と通路切換弁5の入口5Cとの取り付けは、接着剤で固定するようにしてもよいし、ホースバンドやクリップ止めを用いて取り外し可能に取り付けるようにしてもよい。
【0030】
可撓性の管体からなる噴出通路ホース6は、図1などに示すように、その一端6Aが通路切換弁5の一方の出口5Aに、かつ、その他端6Bが槽2の側壁に設けた連通筒体2Bに、それぞれ水密的に取り付けられる。連通筒体2Bは、噴出通路ホース6の他端6Bから噴出するところの、気泡を含む均一高濃度の洗剤液W2が、槽2の内底に沿って噴流するように、槽2の側壁の、可能なかぎり下方に位置させてある。
【0031】
通路切換弁5の他方の出口5Bには、可撓性の管体からなる吐出通路ホース8の入口8A側が水密的に取り付けられている。吐出通路ホース8の出口8B側には、通水抵抗体7が取り外し自在に設けられている。通水抵抗体7は、多数の連続通水孔を有する部材、例えば、スポンジ材、ネット材、フイルター材などからなっており、シャワーヘッド状に構成してある。ギヤポンプ3の出口3Bから吐出通路ホース8に流入してくるところの、気泡を含むより均一高濃度となった洗剤液W4を、通水抵抗体7を通して通水抵抗体7表面に吐出させることで、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5とする。
【0032】
上記構成の泡発生装置1により、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5を得るには、最初に、図6に示すように、洗い水W1となる水道水などの水W0と粉末洗剤Sを槽2内に投入する。
【0033】
その後、図7に示すように、ギヤポンプ3の出口3Bに噴出通路ホース6が連通し、かつ、ギヤポンプ3の出口3Bに吐出通路ホース8が連通しないように、通路切換弁5をセットした状態で、ギヤポンプ3のモータ12を駆動させて駆動歯車13及び従動歯車14を回転させる。すると、吸込みホース4に吸込まれた洗い水W1に、気水混合部材17の空気補給弁17Bが開いてその空気補給弁17Bから流入してきた空気Zが混入するようになる。そして、洗い水W1とこの洗い水W1に混入した空気Zは、ギヤポンプ3により十分に混合されることで、気泡を含む均一高濃度の洗剤液W2となって、図7に示すように、噴出通路ホース6の他端6Bから槽2内に噴出するようになる。
【0034】
気泡を含む均一高濃度の洗剤液W2が噴出通路ホース6の他端6Bから槽2内に噴出すると、槽2内に高濃度の洗剤を均一に含んだ泡W3が発生する。この泡W3と気泡を含む均一高濃度の洗剤液W2とを、ギヤポンプ3を駆動させて、槽2とギヤポンプ3の間で所定時間連続して循環させることにより、図8に示すように、槽2内に高濃度の洗剤を均一に含んだ泡W3が大量に発生する。
【0035】
槽2内に高濃度の洗剤を均一に含んだ泡W3が大量に発生したならば、図9に示すように、通路切換弁5を切り換えて、ギヤポンプ3の出口3B側と吐出通路ホース8とを連通させた状態でギヤポンプ6を駆動させることにより、高濃度の洗剤を均一に含んだ泡W3及び気泡を含む均一高濃度の洗剤液W2にさらに空気Zが混合させられて、気泡を含むより均一高濃度となった洗剤液W4となってギヤポンプ3の出口3Bから吐出通路ホース8に流入してくる。その気泡を含むより均一高濃度となった洗剤液W4を、通水抵抗体7の表面から吐出させることで、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5が得られる。
【0036】
実験によると、容積1リットルの槽2に、水道水1リットルに粉末洗剤15グラムを溶かして得られる洗い水W1を溜めるとともに、ギヤポンプ3の出口3B側と噴出通路ホース6を連通させた状態で、ギヤポンプ3を約1分間作動させると、気泡を含む均一高濃度の洗剤液W2が噴出通路ホース6の他端6Bから槽2内に噴出して、高濃度の洗剤を均一に含んだ泡W3が、槽2内全体に発生した。その状態を約2分継続させた後、通路切換弁5を切り換えてギヤポンプ3の出口3B側と吐出通路ホース8とを連通させると、通水抵抗体7の表面から高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5を吐出させることができた。また、通水抵抗体7を吐出通路ホース8から取り除くことにより、吐出通路ホース8の他端8Bから気泡を含むより均一高濃度となった洗剤液W4を得ることができた。
【0037】
上記構成の泡発生装置1の最適な使用方法は、次の(1)から(5)のとおりである。
【0038】
(1)まず、図6に示すように、洗い水W1となる水道水などの水W0と粉末洗剤Sを槽2内に投入するとともに、ギヤポンプ3の出口3Bに噴出通路ホース6が連通し、かつ、ギヤポンプ3の出口3Bに吐出通路ホース8が連通しないように、通路切換弁5をセットする。
【0039】
(2)次に、図7に示すように、ギヤポンプ3のモータ12を駆動させて駆動歯車13及び従動歯車14を回転させる。
【0040】
(3)次に、駆動歯車13及び従動歯車14を所定時間駆動させて、槽2内に高濃度の洗剤を均一に含んだ泡W3を、必要量、発生させたならば、ギヤポンプ3のモータ12を停止させて駆動歯車13及び従動歯車14の回転を止める。
【0041】
(4)その後、ギヤポンプ3の出口3Bに吐出通路ホース8が連通し、かつ、ギヤポンプ3の出口3Bに噴出通路ホース6が連通しないように、通路切換弁5を切り換えて、再度、ギヤポンプ3のモータ12を駆動させて駆動歯車13及び従動歯車14を回転させることにより、吐出通路ホース8の出口に設けた通水抵抗体7から高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5を吐出させる。
【0042】
(5)通水抵抗体7から高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5を、必要量、吐出させたならば、ギヤポンプ3のモータ12を停止させて駆動歯車13及び従動歯車14の回転を止める。
【0043】
上記(1)から(5)の使用方法により得られた泡(クリーミィな泡)W5は、そのまま手にとって洗顔に利用してもよい。また、泡(クリーミィな泡)W5を、被洗浄物の入った他の洗浄容器内に移すことにより、被洗浄物の泡洗浄に利用するようにしてもよい。
【0044】
上記構成の泡発生装置1によれば、水W0に溶かす洗剤が、粉末状の洗剤であっても、ギヤポンプ3の駆動歯車13及び従動歯車14によって水W0に十分に溶かされるので、洗剤滓の発生を阻止することができる。また、ギヤポンプ3の駆動歯車13及び従動歯車14によって、気泡を含む均一高濃度の洗剤液W2が噴出通路ホース6の他端6Bから槽2内に噴出させられるので、槽2内に高濃度の洗剤を均一に含んだ泡W3を短時間で大量に発生させることができる。また、通路切換弁5を切り換えることで、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5を簡単に得ることができる。また、気泡を含む均一高濃度の洗剤液W2が噴出通路ホース6の他端6Bから槽2内に噴出させられるので、その気泡を含む均一高濃度の洗剤液W2と一緒に槽2内に残っていた洗い水W1が槽2内で強く掻き回される状態になるため、粉末洗剤Sがより均一に溶かされる。
【0045】
図10は、泡発生装置の他実施形態その1を示す。図10において、図1と同一符号は、同一内容を表している。図10の他実施形態その1では、通路切換弁5と吐出通路ホース8と通水抵抗体7とを削除して、ギヤポンプ3の出口3Bに噴出通路ホース6の一端6Aを、直に連結させる構造にしている。この構造の場合には、槽2内に発生させた高濃度の洗剤を均一に含んだ泡W3を、手などにより取り出して洗浄等に利用する。
【0046】
図11は、泡発生装置の他実施形態その2を示す。図11において、図1と同一符号は、同一内容を表している。図11の他実施形態その2では、吐出通路ホース8の出口から上記一実施形態の泡発生装置1における通水抵抗体7を取り除いた構造にしている。この構造の場合には、気泡を含むより均一高濃度の洗剤液W4を、直接、吐出通路ホース8の出口から取り出して利用するようにすることで、泡発生装置1を、気泡を含むより均一高濃度の洗剤液W4の洗剤液製造装置として利用することができる。
【0047】
さらに、上記本実施形態の泡発生装置1において、槽2に投入する水を軟水にしたい場合には、水道水を軟水にするための軟水製造装置(図示せず)を設けて、この軟水製造装置で得られた軟水を槽2に内に投入するようにすればよい。
【0048】
さらに、上記本実施形態の泡発生装置1では、槽2は、その槽2の上端開放部を蓋体2Aで覆う構造にしているが、これに限定されない。槽2は、水及び洗剤を投入する投入口を有するタンク状(容器状)のものであってもよい。また、槽2に透明窓を設け、その透明窓から高濃度の洗剤を均一に含んだ泡W3の発生状況を確認できるようにしてもよい。

(ハ)次に、ギヤポンプ26を駆動させると、洗濯槽22内の洗い水W1が吸込み通路手段27に流入してその洗い水W1に空気Zがギヤポンプ26の入口の手前で混入された後、その洗い水W1及びこの洗い水W1に混入した空気Zが、ギヤポンプ26内で十分に混合されることで、気泡を含む均一高濃度の洗剤液W2となり、しかも、その気泡を含む均一高濃度の洗剤液W2が噴出通路手段29の他端から洗濯槽22内に噴出することによって、洗濯槽22内底から高濃度の洗剤を均一に含んだ泡W3を発生させる。そして、ギヤポンプ26が駆動している間は、気泡を含む均一高濃度の洗剤液W2が、高濃度の洗剤を均一に含んだ泡W3にならずに洗濯槽22内に残っている洗い水W1及び高濃度の洗剤を均一に含んだ泡W3と一緒になって、吸込み通路手段27―ギヤポンプ26―連結管32―通路切換弁28―噴出通路手段29―洗濯槽22の順で循環するので、高濃度の洗剤を均一に含んだ泡W3が洗濯槽22内底から、連続して発生する。
【0060】
(ニ)次に、ギヤポンプ26を所定時間駆動させて、洗濯槽22内に高濃度の洗剤を均一に含んだ泡W3が、必要量、得られると、通路切換弁28が自動的に切り換わり、ギヤポンプ26の出口側と泡吐出流路手段31とを連通させる。

【0067】
上記一実施形態の泡発生機能付き洗濯機20では、ギヤポンプ26の駆動歯車13及び従動歯車14によって洗い水W1及び空気Zが混合されることと、噴出通路ホース6の他端6Bから洗濯槽22内に噴出する気泡を含む均一高濃度の洗剤液W2により、その気泡を含む均一高濃度の洗剤液W2と一緒に洗濯槽22内に残っていた洗い水W1が洗濯槽22内で強く掻き回されることとが相俟って、洗い水W1に粉末洗剤Sが均一に溶けて、洗濯槽22内に高濃度の洗剤を均一に含んだ泡W3を短時間で大量に発生させることができ、高濃度の洗剤を均一に含んだ泡W3を洗濯槽22内の洗濯物34に短時間で浸透させることができ、しかも、洗剤滓の発生を阻止することができる。また、通路切換弁28を切り換えることで、高濃度の洗剤を均一に含んでなるきめの細かい泡(クリーミィな泡)W5を、洗濯槽22内の洗濯物34の上に、短時間で大量に落下させることができる。
【0068】

BACKGROUND OF THE INVENTION
The present invention relates to a foam generating device and a washing machine with a foam generating function.
[0002]
[Prior art]
Conventionally, as a foam generating device for a washing machine or the like, as shown in FIG. 16, a member having a large number of continuous water passage holes (hereinafter referred to as “continuous”) in washing water (washing water or washing water) stored in a tub 100. The foam 104 is generated from the continuous water-hole member 101 by sinking 101) (referred to as a water-hole member) and sending air into the continuous water-hole member 101 by the air pump 102. It has been known that a tube 103 that is connected to the continuous water passage hole member 101 and extends thinly toward the upper part of the tank 100 is allowed to drop from the upper side of the tank 100 toward the inner bottom of the tank 100.
[0003]
Furthermore, as a washing machine with foam generating function, air was sent by an air pump to the lower side of the pulsator provided on the inner bottom of the washing tub to generate foam (bubbles), and the foam was provided in the pulsator. There has been known one in which a plurality of bubble passage holes are ejected to adhere to the surface of the laundry or between the laundry (for example, see Patent Document 1).
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 5-200183 (lines 31 to 46 on the right side of page 3)
[0005]
[Problems to be solved by the invention]
In the washing water stored in the tank 100 in the foam generating apparatus, the detergent is poured into the tank 100 and then obtained by flowing water such as tap water, so that the detergent is in a uniformly dissolved state. is not. Moreover, when the detergent is powdery, the detergent may not be dissolved in water. Therefore, the foam generated from the continuous water passage hole member 101 has a problem that the detergent does not become a foam in which the detergent is uniformly dissolved, and the detergent adheres to the surface of the continuous water passage hole member 101. Moreover, since bubbles generated from the continuous water passage hole member 101 are collected in the thin tube 103 and dropped from the upper end side of the thin tube 103 toward the inner bottom of the tank 100, the necessary amount of bubbles is obtained. There was a problem that it took time.
[0006]
Furthermore, in the washing machine of the above-mentioned Japanese Patent Laid-Open No. 5-200183, bubbles are ejected from a large number of bubble passage holes provided in the pulsator in a state where the washing water is accumulated up to the high water level of the washing tub. Is not a foam containing a high-concentration detergent, and a large amount of foam does not occur, so that there is a problem that the effect of washing the foam cannot be sufficiently obtained.
[0007]
The first object of the present invention has been made in view of the above-mentioned problems, and is to provide a foam generating apparatus capable of efficiently producing a large amount of foam uniformly containing a high concentration detergent. .
[0008]
The second object of the present invention has been made in view of the above problems, and provides a foam generating apparatus that can efficiently produce fine bubbles that uniformly contain a high concentration detergent. It is in.
[0009]
The third object of the present invention was made in view of the above problems, and provides a washing machine with a foam generating function capable of efficiently producing foam uniformly containing a high concentration detergent. is there.
[0010]
The fourth object of the present invention is made in view of the above problems, and is a washing machine with a foam generating function capable of efficiently producing fine foam that uniformly contains a high concentration detergent. It is to provide.
[0011]
[Means for Solving the Problems]
The first object of the present invention is to store a wash water obtained by mixing a small amount of water and a detergent, and to mix the wash water and air while mixing the wash water sucked from the tank with the wash water and air. At least pump means for spraying into the tank, and driving the pump means for a predetermined time to circulate the wash water and air repeatedly between the tank and the pump means, thereby repeatedly supplying the wash water and air to the tank. This can be achieved by jetting into the tank and generating bubbles in the tank.
[0012]
According to this configuration, even if the detergent is not uniformly dissolved in the washing water stored in the tank, the detergent and air mixed in the washing water are sufficiently mixed by the pump means, so that the suction from the tank is performed. Since the washing water becomes a uniform high-concentration detergent liquid containing bubbles and is ejected from the discharge port side of the pump means, bubbles containing a high-concentration detergent uniformly are generated in the tank. In addition, since the uniform high-concentration detergent liquid containing the bubbles is repeatedly ejected into the tank, bubbles uniformly containing the high-concentration detergent are generated in the tank in a short time. Moreover, even if the detergent put into the tank is powdery and hardened, the solidified detergent is dissolved by the pump means by the pump means.
[0013]
The second object of the present invention is to store a wash water obtained by mixing a small amount of water and a detergent, and to mix the wash water and air while mixing the wash water sucked from the tank with the wash water and air. At least pump means for spraying into the tank, and driving the pump means for a predetermined time to circulate the wash water and air repeatedly between the tank and the pump means, thereby repeatedly supplying the wash water and air to the tank. In the foam generating device that is jetted into the tank to generate bubbles in the tank, the pump means has a gear pump and one end communicated with the inlet side of the gear pump, and the other end communicated with the tank. A suction passage means, an air suction means disposed on the inlet side of the gear pump, a passage switching valve connected to the outlet side of the gear pump, and one end to one outlet of the passage switching valve. And a foam discharge passage having an end connected to the other outlet of the passage switching valve and a water flow resistor provided at the other end. And the foam pump and the washing water are caused to flow resistance by switching the passage switching valve and driving the gear pump so that the outlet side of the gear pump and the foam discharge passage means are in communication with each other. This can be achieved by discharging bubbles from the surface of the water flow resistor by passing through the body.
[0014]
According to this configuration, the washing water sucked from the tank by the gear pump is used as a uniform high-concentration detergent liquid containing bubbles, and the uniform high-concentration detergent liquid containing the bubbles is jetted into the tank. Bubbles that uniformly contain a high concentration of detergent are generated in a short time. In addition, if the required amount of foam containing a high-concentration detergent uniformly is generated in the tank, the gear pump is driven in a state where the outlet of the gear pump communicates with the foam discharge passage means by switching the passage switching valve. Then, air is mixed with the foam that uniformly contains the high-concentration detergent generated in the tank and the washing water remaining in the tank, resulting in a more uniform high-concentration detergent liquid containing bubbles. , Ejected from the outlet of the gear pump. The detergent liquid having a more uniform and high concentration including the ejected bubbles is discharged from a water flow resistor provided at the other end of the foam discharge flow path means, thereby uniformly containing a high concentration detergent. It can be taken out in a short time as fine bubbles (creamy bubbles).
[0015]
The third object of the present invention is to provide a washing tub for storing washing water obtained by mixing a small amount of water and a detergent, and the washing water and air mixed with the washing water sucked from the washing tub. And at least a stirring means for stirring the laundry put in the washing tub, and driving the pump means for a predetermined time to supply the washing water and air to the washing tub. By repeatedly circulating between the pump means, the washing water and air can be repeatedly ejected into the washing tub to generate bubbles in the washing tub.
[0016]
According to this structure, even if the detergent is not uniformly dissolved in the washing water stored in the washing tub, the detergent and air mixed in the washing water are sufficiently mixed by the pump means, Since the washing water becomes a uniform high-concentration detergent solution containing bubbles and is ejected from the outlet side of the pump means, bubbles containing a high-concentration detergent uniformly are generated in the washing tub. And since the uniform high concentration detergent liquid containing the bubbles is repeatedly ejected to the washing tub, bubbles uniformly containing the high concentration detergent are generated in the washing tub in a short time. Even if the detergent put into the washing tub is powdery and hardened, the hardened detergent is dissolved by the pump means by the pump means. In addition, since the uniform high concentration detergent liquid containing bubbles is repeatedly ejected from the outlet side of the pump means into the washing tub, a large amount of bubbles containing the high concentration detergent uniformly in the washing tub in a short time.
