図1は、本発明の実施の形態1に係る洗濯機1の側面側から視た構成図である。図2は洗濯機1の要部を上部から視た平面図である。
またさらに上記のように内軸19と外軸8との間に連結ギアなど無くとも、回転切換部20によって内軸19を回転させずに外軸8のみを回転させると、支持体7とともに洗濯槽13が外軸8の軸線廻りに回転するとともに、回転しない円盤18上を転動輪16が接触しながら転動して洗濯槽13が洗濯槽回転軸14の軸線廻りに回転することができるようになる。たとえば最も簡単には、内軸19はモータ21を貫通させてモータ21の下方側(反洗濯槽13側)で固定すれば、内軸19だけを確実に回転しないようにできる。勿論、内軸19を回転する際には、この固定は解除する。なお、各部との摩擦により内軸19は回転し難いので、上記のような内軸19の確実な固定は必ずしも無くても同様な動きとなる。
また上記の実施の形態1では、内軸19および外軸8の軸線の延長上に設けたモータ21で支持体7や洗濯槽13を回転する方式、いわゆるダイレクトモータ駆動で示したが、内軸19または外軸8とは異なる軸線上で回転駆動するモータからベルト等により伝達されて内軸19または外軸8が回転駆動される方式であっても同様な動作の実現が可能であることは勿論である。

図13は、本発明に関連する発明にかかる実施例1における洗濯機101Rの側面側から視た構成図である。
まず、洗濯機101Rの利用者は、筐体開閉蓋3Rを開けて、洗濯物を洗濯槽9Rの内側に収納する。筐体開閉蓋3Rを閉じた後、利用者がスイッチ(図示せず)を押すと、外槽支持部材7Rに設けられた重量センサによる検知や洗濯槽9Rを低速で回転させた際のモータ12Rのトルク変化の検知などの図示しない手段により、外槽5R全体の重量変化を検知して洗濯物の重量を算出する。排水路8Rの排水弁を閉じた後、洗濯物の重量に合わせて外槽5Rの内側に、給水管(図示せず)から自動で給水が行われる。必要量の給水が完了した後、利用者が洗濯槽9Rの内側に洗剤を投入し、洗浄動作が開始される。なお、洗濯物の重量などを検知せず、利用者が手動で給水管の弁などを開閉して、外槽5Rの内側に水を溜めてもよい。また、洗濯槽9Rの内側に自動的に洗剤が投入されてもよく、さらには、給水に混ぜて洗濯槽9Rに投入されてもよい。また、洗濯槽9Rに洗剤が投入するタイミングは、洗濯槽9Rが回転する前であることが望ましいが、それ以外のタイミングであってもよい。
以下に、本発明に関連する発明にかかる実施例2の洗濯機について説明する。本実施例2の洗濯機は、実施例1の洗濯機と基本的な構成は同じであるが、レール13Rを回転可能にした点が異なっている。そのため、本相違点を中心に説明する。図14は、本実施例2に係る洗濯機102Rの側面側から視た構成図である。本実施例2に係る洗濯機102Rは、実施例1の洗濯機101Rに加えて、洗濯槽回転軸11Rの軸線Lを中心にレール13Rを、その周方向に回転可能にしたものである。本実施例2では、レール13Rの下方に、環状にレール回転保持部22Rが設けられており、レール13Rに固定され、断面が逆T字状のレール回転嵌合部21Rが、レール回転保持部22Rに形成された逆T字状の凹部に噛み合っている。このレール回転嵌合部21Rは、レール回転保持部22Rとレール13Rとが軸線L方向に分離されないようにするためのものであり、レール13Rの洗濯槽回転軸11Rの軸線Lを中心にした周方向の全周にわたって環状に設けられていても良いし、周方向の所々の部分的な位置に複数箇所設けられているだけでもよい。レール回転嵌合部21Rとレール回転保持部22Rとの間には図示しないベアリングが設けられ、レール回転嵌合部21Rとレール回転保持部22Rとが摺動しながら、洗濯槽回転軸11Rの軸線Lを中心にレール13Rが回転できる。また上記とは逆に、レール回転保持部22Rを断面がT字状に形成し、レール13Rの下方にレール回転保持部22Rが噛み合うようにしたT字状の凹部を設けてもよく、上記よりも部品点数が少なく簡単な構成となる。またレール回転嵌合部21Rとレール回転保持部22Rの凹部の断面はL字状などT字状以外の形状であっても良い。
以下に、本発明に関連する発明にかかる実施例3の洗濯機について説明する。本実施例3の洗濯機は、実施例2の洗濯機102Rと基本的な構成は同じであるが、レール13Rを回転させる構成が異なっている。そのため、本相違点を中心に説明する。図15(a)は、本実施例3に係る洗濯機103Rの側面側から視た構成図である。図15(a)に示すように、本実施例に係る洗濯機103Rでは、洗濯槽回転軸11Rの軸線Lを中心に回転するレール回転軸27Rが洗濯槽回転軸11Rの外周側に設けられ、レール回転軸27Rは、回転切換部30Rを介してモータ12Rに接続されている。なお、洗濯槽回転軸11Rとレール回転軸27Rとの間は回転差があっても水が漏れないよう水密されている。洗濯槽回転軸11Rとレール回転軸27Rとは同一の軸線Lを中心に回転し、外槽5Rに固定された外槽軸受6Rによって回転可能に支持されている。レール回転軸27Rとレール13Rとは放射状に伸びた複数本のレール回転支持部28Rによって連結されており、レール回転軸27Rが洗濯槽回転軸11Rの軸線Lを中心に回転すると、レール13Rが洗濯槽回転軸11Rの軸線Lを中心に回転する。レール13Rとレール回転支持部28Rとの接続部、及びレール回転軸27Rとレール回転支持部28Rとの接続部は、レール可倒支点29Rで接続されている。このレール回転支持部28Rは、レール可倒支点29Rを中心に回動可能に構成されているため、レール回転支持部28Rの角度が変更できる。そのため、レール支持駆動部16Rを駆動してレール回転保持部22Rおよびレール13Rを洗濯槽回転軸11Rの軸線L方向へ移動できるようになっており、実施例2と同様にレール13Rと転動輪19Rを接触するか離間するかを変更できる。尚、本発明に関連する発明の「洗濯槽を回転させるための洗濯槽用動力発生部と兼ねられている駆動用動力発生部」の一例は、本実施例のモータ12Rに相当し、本発明に関連する発明の駆動軸の一例は、本実施例のレール回転軸27Rに相当する。また、本発明に関連する発明の伝達部材及び棒状部材の一例は、本実施例のレール回転支持部28Rに相当する。また、このレール回転軸27Rから撹拌翼17Rに伝達される力が、本発明に関連する発明の洗濯槽が自転する回転力以外の力の一例に相当する。本実施例3では、洗濯槽9Rが自転する洗濯槽回転軸11Rの回転力とともに、レール回転軸27Rの回転力によっても、撹拌翼17Rが自転することになる。又、本実施例の回転切換部30Rには、洗濯槽回転軸11Rを回転するか、レール回転軸27Rを回転するか、双方を同時に回転するかを切り換えるためにギヤやクラッチなどを適宜内蔵することが出来、洗濯槽回転軸11R及びレール回転軸27Rの回転速度及び回転方向を様々に設定することが出来る。以下に、本実施例3の洗濯機103Rの動作について、回転切換部30Rの構成とともに説明する。この回転切換部30Rの一例として、従来の洗濯機と同様の簡易な構成を用いた場合について説明する。従来の洗濯機は、洗濯槽の底部に洗濯槽の回転軸(外軸)と同一直線状の回転軸(内軸)を中心に回転する撹拌翼を備えており、このような洗濯機の回転切換部は、洗浄及び濯ぎ動作時には内軸だけを回転して底部の撹拌翼だけを回転し、脱水動作時には内軸と外軸を一体で回転して洗濯槽だけを回転するような簡単な構成が一般的である。この従来の回転切換部と同様の簡単な構成の回転切換部30Rを用いた場合、洗浄及び濯ぎ動作時には、従来の内軸に相当する洗濯槽回転軸11Rだけを軸線Lを中心に回転すると、洗濯槽9Rが軸線Lを中心に回転し、レール13Rは回転しないので転動輪19Rがレール13R上を転動して撹拌翼17Rが軸線Mを中心に回転する。また脱水動作時には、従来の外軸に相当するレール回転軸27Rと内軸に相当する洗濯槽回転軸11Rとを一体で軸線Lを中心に回転すると、転動輪19Rは洗濯槽9Rと一体で軸線Lを中心に公転し、レール13R上を転動しないため、撹拌翼17Rは軸線Mを中心には回転せず、洗濯槽9Rだけが軸線Lを中心に回転する。本実施例3を以上のように構成したので、洗濯槽9Rと撹拌翼17Rの回転方向や回転数をそれぞれ自在に選定できることによる効果の点では実施例2に劣るが、その他の点では実施例2と同様な効果を奏する上、実施例2のようなレール13Rを回転するためのレールモータ26Rは不要となり、より簡単な構成とすることができる。
以下に、本発明に関連する発明にかかる実施例4の洗濯機について説明する。本実施例4の洗濯機は、実施例3の洗濯機103Rと基本的な構成は同じであるが、撹拌翼17Rを回転させる構成が異なっている。そのため、本相違点を中心に説明する。図16は、実施例4に係る洗濯機104Rの側面側から視た構成図である。上述した実施例1ないし3の洗濯機では、レール13Rに接触させた転動輪19Rを転動して、回転軸18Rの軸線Mを中心に撹拌翼17Rを回転させたが、本実施例4に係る洗濯機104Rでは、レール13Rを用いずに撹拌翼17Rが回転可能に構成されている。本実施例4に係る洗濯機104Rには、洗濯槽回転軸11Rの軸線Lを中心に回転する駆動軸44Rが洗濯槽回転軸11Rの外周側に設けられ、この駆動軸44Rは回転切換部30Rを介してモータ12Rに接続されている。洗濯槽回転軸11Rと駆動軸44Rとは同一の洗濯槽回転軸11Rの軸線Lを中心に回転する2重構造で構成されており、駆動軸44Rは外槽5Rに固定された外槽軸受6Rによって回転可能に支持されている。回転切換部30Rには、洗濯槽回転軸11Rを回転するか、駆動軸44Rを回転するか、又は洗濯槽回転軸11R及び駆動軸44Rを同時に回転するかを切り換えるためにギヤやクラッチなどが内蔵されている。回転切換部30Rにより、実施例3における洗濯槽回転軸11Rとレール回転軸27Rと同様な種々の回転パターンで、本実施例の洗濯槽回転軸11Rと駆動軸44Rとを回転させることが可能である。本実施例では、本発明に関連する発明の転動部の一例である転動輪49Rは、回転軸18Rの軸線Mの中心を凹部にした曲面状に形成され、その外周部が駆動軸44Rに直接接触しており、駆動軸44Rが洗濯槽回転軸11Rの軸線を中心に回転すると、転動輪49Rが駆動軸44R上を転動し、撹拌翼17Rが回転軸18Rの軸線Mを中心に回転する。尚、本発明に関連する発明の「洗濯槽を回転させるための洗濯槽用動力発生部と兼ねられている駆動用動力発生部」の一例は、本実施例のモータ12Rに相当し、本発明に関連する発明の洗濯槽自転軸の外側に設けられ、接触部材と兼ねられている駆動軸の一例は、本実施例の駆動軸44Rに相当する。
以下に、本発明に関連する発明にかかる実施例5の洗濯機について説明する。本実施例5の洗濯機は、実施例3の洗濯機103Rと基本的な構成は同じであるが、撹拌翼17Rを回転させる構成が異なっている。そのため、本相違点を中心に説明する。図17(a)は、本実施例5に係る洗濯機105Rの側面側から視た構成図である。本実施例5に係る洗濯機105Rは、実施例3の洗濯機103Rと異なり、レール13Rを用いずに別の方法で撹拌翼17Rを回転するようにしたものである。本実施例5に係る洗濯機105Rでは、実施例3と同様に、洗濯槽回転軸11Rの軸線Lを中心に回転する撹拌翼駆動軸37R(実施例3ではレール駆動軸27R)が洗濯槽回転軸11Rの外周側に設けられ、その撹拌翼駆動軸37Rは回転切換部30Rを介してモータ12Rに接続されている。洗濯槽回転軸11Rと撹拌翼駆動軸37Rとは、同一の洗濯槽回転軸11Rの軸線Lを中心に回転し、外槽5Rに固定された外槽軸受6Rによって回転可能に支持されている。回転切換部30Rは、洗濯槽回転軸11Rを回転するか、撹拌翼駆動軸37Rを回転するか、又は洗濯槽回転軸11R及び撹拌翼駆動軸37Rの双方を回転するか、を切り換えるためにギヤやクラッチなどを内蔵している。回転切換部30Rにより、実施例3における洗濯槽回転軸11Rとレール回転軸27Rと同様な種々の回転パターンで、本実施例の洗濯槽回転軸11Rと撹拌翼駆動軸37Rとを回転させることが可能である。回転軸18Rの洗濯槽9Rの外側には、上述した各実施例1において説明した転動輪19Rの代わりに、撹拌翼17Rおよび回転軸18Rと一体で回転軸18Rの軸線Mを中心に回転する回転輪40Rが設けられている。撹拌翼駆動軸37Rと複数の回転輪40Rとは、回転輪40R毎に撹拌翼駆動軸37Rの軸線L方向へ位置を変えて、かつ回転輪40R毎に伝達ベルト38Rによって連結されており、撹拌翼駆動軸37Rの回転が回転輪40Rに伝達されるようになっている。伝達ベルト38Rは樹脂製の繊維構造のものや合成ゴムなどを用いることが出来る。又、回転輪40Rおよび撹拌翼駆動軸37Rにおける伝達ベルト38Rの係り部には、溝や仕切が設けられて伝達ベルト38Rがそれぞれの軸方向へずれたり、外れたりしないようになっている。尚、図17では、回転輪40Rと撹拌翼駆動軸37Rが伝達ベルト38Rによって直接連結されているが、2つの軸が平行に配置されていないため、直接連結することによって伝達ベルト38Rに無理な力が加わって軸方向にずれやすい場合がある。この場合には、伝達ベルト38Rにかかる力を緩和するために、回転輪40Rと撹拌翼駆動軸37Rの間の洗濯槽9Rの外壁にプーリー等を設けてもよい。このプーリーと回転軸40Rをベルトで連結し、プーリーと撹拌翼駆動軸37Rをベルトで連結する構成とすることによって、伝達ベルトにかかる負荷を低減できる。このプーリーにも溝が形成されており、ベルトの軸方向へのずれが抑制される。尚、本発明に関連する発明の回転部の一例は、本実施例の回転輪40Rに相当し、本発明に関連する発明の駆動軸の一例は、本実施例の撹拌翼駆動軸37Rに相当する。又、本発明に関連する発明の「洗濯槽を回転させるための洗濯槽用動力発生部と兼ねられている駆動用動力発生部」の一例は、本実施例のモータ12Rに相当し、本発明に関連する発明のベルト状部材の一例は、本実施例の伝達ベルト38Rに相当する。
以下に、本発明に関連する発明にかかる実施例6の洗濯機について説明する。本実施例6の洗濯機は、実施例1の洗濯機と基本的な構成は同じであるが、レールを2つ備えている点が異なる。そのため、本相違点を中心に説明する。図18は、本実施例6に係る洗濯機106Rの側面側から視た構成図である。本実施例6に係る洗濯機106Rは、実施例1の洗濯機101Rに加えて、1つの転動輪が転動するレールを2つ(第1のレール13aR、第2のレール13bR)備えるようにしたものである。洗濯槽9Rの外側であって外槽5Rの内側には、洗濯槽回転軸11Rの軸線Lを中心に環状に形成され、本発明に関連する発明の転動部の一例である転動輪19Rを転動可能に支持した第1のレール13aRと第2のレール13bRとが設けられている。尚、この第1のレール13aRと第2のレール13bRのそれぞれが、本発明に関連する発明の接触部材の一例に相当し、本発明に関連する発明の第1レール部材の一例が本実施例の第1のレール13aRに相当し、本発明に関連する発明の第2レール部材の一例が本実施例の第2のレール13bRに相当する。第1のレール13aRには転動輪19Rの下方側が接触して転動し、第2のレール13bRには転動輪19Rの上方側が接触して転動する。転動輪19Rが第1のレール13aRあるいは第2のレール13bRのいずれか一方の上を転動することにより、撹拌翼17Rは回転軸18Rを中心に回転する。第1のレール13aRは、第1のレール弾性部15aRを介して第1のレール支持部14aRに支持されており、この第1のレール支持部14aRは、外槽5Rに固定された第1のレール支持駆動部16aRに洗濯槽回転軸11Rの軸方向(この実施例では垂直方向)に移動可能に支持されている。この第1のレール弾性部15aR、第1のレール支持部14aRおよび第1のレール支持駆動部16aRは、洗濯槽回転軸11Rの軸線を中心に周方向に間隔をおいて複数箇所に配置されている。このレール支持駆動部16aRが、本発明に関連する発明の第1の離間部の一例に相当する。また第2のレール13bRは、第2のレール弾性部15bRを介して第2のレール支持部14bRに支持されており、この第2のレール支持部14bRは、外槽5Rに固定された第2のレール支持駆動部16bRに洗濯槽回転軸11Rの軸方向(この実施例では垂直方向)に移動可能に支持されている。この第2のレール弾性部15bR、第2のレール支持部14bRおよび第2のレール支持駆動部16bRは、洗濯槽回転軸11Rの軸線を中心に周方向に間隔をおいて複数箇所に配置されている。このレール支持駆動部16bRが、本発明に関連する発明の第2の離間部の一例に相当する。なお、第1のレール支持駆動部16aR、及び第2のレール支持駆動部16bRは、それぞれ筐体2Rに固定されてもよい。第1のレール弾性部15aRにより、洗濯槽回転軸11Rの軸線Lを中心にした洗濯槽9Rの回転ぶれに伴って転動輪19Rから第1のレール13aRに加えられる過度の力を低減することができる。なお、第1のレール弾性部15aR、第1のレール支持部14aRおよび第1のレール支持駆動部16aRの数は何個であってもよいが、多い方が回転ぶれを低減する効果は高く、また転動輪19Rと第1のレール13aRとの接触がより確実である。また、第2のレール弾性部15bRにより、洗濯槽回転軸11Rの軸線を中心にした洗濯槽9Rの回転ぶれに伴って転動輪19Rから第2のレール13bRに加えられる過度の力を低減することができる。なお、第2のレール弾性部15bR、第2のレール支持部14bRおよび第2のレール支持駆動部16bRの数は何個であってもよいが、多い方が回転ぶれを低減する効果は高く、また転動輪19Rと第2のレール13bRとの接触がより確実である。また、第1のレール13aRあるいは第2のレール13bRと転動輪19Rとの間の接触領域には、双方にギヤなどの噛み合わせ構造を備えたり、ゴムなどの摩擦が大きい材料を備えたりすると、空転などが発生し難くなり、転動がより確実になる。第1のレール支持駆動部16aRが駆動することで、第1のレール支持部14aRが洗濯槽回転軸11Rの軸方向(この実施例では垂直方向)に出し入れされ、第1のレール13aRを押し上げると転動輪19Rと接触し、第1のレール13aRを引き下げると転動輪19Rと非接触になる。又、第2のレール支持駆動部16bRが駆動することで、第2のレール支持部14bRが洗濯槽回転軸11Rの軸方向(この実施例では垂直方向)に出し入れされ、第2のレール13bRを押し下げると転動輪19Rと接触し、第2のレール13bRを引き上げると転動輪19Rと非接触になる。転動輪19Rを第1のレール13aRもしくは第2のレール13bRのどちらか一方に接触させるようにして、洗濯槽回転軸11Rの軸線Lを中心に洗濯槽9Rを回転させると、回転軸18Rの軸線Mを中心に撹拌翼17Rが回転させられ、その時、転動輪19Rが第1のレール13aRか第2のレール13bRのどちらに接触しているかで回転方向が逆になる。例えば、洗濯槽回転軸11Rを矢印A方向(上方から見て反時計回り)に回転させた場合、第2のレール13bRを転動輪19Rに接触させずに、第1のレール13aRを接触させると、転動輪19Rは、矢印B方向(上方からみた反時計回り)に回転することとなる。一方、第1のレール13aRを転動輪19Rに接触させずに、第2のレール13bRを接触させると、転動輪19Rは、矢印C方向(上方からみた時計回り)に回転することになる。なお、洗濯槽9Rを高速回転する脱水動作時には、転動輪19Rが第1のレール13aRおよび第2のレール13bRの両方ともに接触しないようにしておくことが望ましい。理由としては脱水動作時には撹拌翼17Rの回転は特に不要であり、また転動輪19Rと第1のレール13aRあるいは第2のレール13bRとの接触による回転ロスや騒音を抑制できるからである。実施例6は以上のように構成したので、実施例1と同様な効果を奏するとともに、対応するレール支持駆動部16(第1のレール支持駆動部16aRと第2のレール支持駆動部16bR)を駆動して転動輪19Rが接触するレール(第1のレール13aRと第2のレール13bR)を切り換えることで、洗濯槽9Rの洗濯槽回転軸11Rの軸線を中心にした回転方向を変更しなくとも、撹拌翼17Rの回転軸18Rの軸線Mを中心にした回転方向を変更することができる。また第1のレール13aRと第2のレール13bRとは外周径が異なっているため、転動輪19Rが接触するレール13が切り替わると、洗濯槽9Rの洗濯槽回転軸11Rの軸線Lを中心にした回転速度を変えなくとも、撹拌翼17Rの回転方向とともに回転速度も簡単に変更できる。
以下に、本発明に関連する発明にかかる実施例7の洗濯機について説明する。本実施例7の洗濯機は、実施例6の洗濯機と基本的な構成は同じであるが、洗濯槽9Rの形状が異なっている。そのため、本相違点を中心に説明する。図19は、本実施例7に係る洗濯機107Rの側面側から視た構成図である上記各実施例では、洗濯槽9Rの底部側を半球面などの曲面形状で形成し、曲面形状の内側に洗濯槽回転軸11Rの軸線とは傾斜した回転軸18Rの軸線を中心に回転する2つの撹拌翼17Rを有したものを示したが、本実施例7に係る洗濯機107Rは、一般的な縦型の洗濯機におけるのと同様に、円筒状の洗濯槽79Rの底部に洗濯槽回転軸11Rと同一の軸線Lを中心に回転する底部撹拌翼31Rを1つ設けるとともに、洗濯槽79Rの円筒側面の一部を平面にした撹拌翼取付部39Rに、2つの撹拌翼17R(第1の撹拌翼17aRと第2の撹拌翼17bR)を設けたものである。本実施例7に係る洗濯機107Rでは、円筒状の洗濯槽79Rの底部に洗濯槽回転軸11Rが固定され、また洗濯槽回転軸11Rの軸線Lを中心に回転する底部撹拌翼回転軸32Rが洗濯槽回転軸11Rの同軸内側に設けられ、円筒状の洗濯槽79Rの底部に洗濯槽回転軸11Rと同一の軸線Lを中心に回転する底部撹拌翼31Rが設けられている。洗濯槽回転軸11Rと底部撹拌翼回転軸32Rとは外槽5Rを貫通して、回転切換部30Rを介してモータ12Rに接続されている。洗濯槽回転軸11Rと底部撹拌翼回転軸32Rとは同一の軸線Lを中心に回転し、外槽5Rに固定された外槽軸受6Rによって回転可能に支持されている。回転切換部30Rには、洗濯槽回転軸11Rを回転するか、底部撹拌翼回転軸32Rを回転するか、を切り換えるためにギヤやクラッチなどが内蔵されている。第1の撹拌翼17aRの回転軸である第1の回転軸18aRには、洗濯槽79Rを貫通した外側に、第1の回転軸18aRと一体となって回転する第1の転動輪19aRが設けられており、第1の回転軸18aRは、洗濯槽79Rの円筒側面の一部を平面にした撹拌翼取付部39Rに固定された第1の洗濯槽軸受20aRによって回転可能に支持されている。又、第2の撹拌翼17bRの回転軸である第2の回転軸18bRには、洗濯槽79Rを貫通した外側に、第2の回転軸18bRと一体となって回転する第2の転動輪19bRが設けられ、洗濯槽79Rの円筒側面の一部を平面にした撹拌翼取付部39Rに固定された第2の洗濯槽軸受20bRによって回転可能に支持されている。第1の撹拌翼17aR、第1の回転軸18aR、及び第1の転動輪19aRと、第2の撹拌翼17bR、第2の回転軸18bR、及び第2の転動輪19bRとは、洗濯槽回転軸11Rの軸方向から見て洗濯槽回転軸11Rの軸線を中心に対向した位置に設けられており、また第1の回転軸18aRと第2の回転軸18bRの軸線は洗濯槽回転軸11Rの軸方向へずらして設けられている。なお、撹拌翼取付部39Rが平面形状をしているのは撹拌翼17Rと洗濯槽79Rとの間に大きな隙間が生じて、洗濯物が挟まったりしないようにするためである。これら第1の転動輪19aR、第2の転動輪19bRが、本発明に関連する発明の転動部の一例に相当する。
以下に、本発明に関連する発明にかかる実施例8の洗濯機について説明する。本実施例8の洗濯機は、実施例1の洗濯機と基本的な構成は同じであるが、外槽がもうけられていない点が異なっている。そのため、本相違点を中心に説明する。図20は、本実施例8に係る洗濯機108Rの側面側から視た構成図である。上記各実施例では、洗濯槽9R、79Rの壁面に通水孔を備えた上で洗濯槽の外側に貯水するための外槽5Rを備えたもので示したが、この実施例8の洗濯機は、実施例1に対して洗濯槽9Rの壁面に通水孔がない洗濯槽89Rを有し、かつ外槽を持たない構成としたものである。本実施例8の洗濯槽89Rの外側下方に保持体33Rが設けられ、この保持体33Rは筐体2Rの四隅から上記各実施例における外槽支持部材7Rと同様な保持体支持部34Rによって吊られながら支持されている。洗濯槽89Rの底部には洗濯槽回転軸11Rが固定されており、洗濯槽回転軸11Rは保持体33Rに設けられた保持体軸受35Rによって回転可能に支持され、保持体33Rに固定されたモータ12Rに接続されている。これにより、モータ12Rで洗濯槽回転軸11Rを回転すると、洗濯槽89Rは洗濯槽回転軸11Rの軸線Lを中心に水平方向に回転する。洗濯槽回転軸11Rは中空で形成され、その中空部は洗濯槽89R内の水を洗濯槽89R外に排出するための通路であり、回転する洗濯槽回転軸11Rと回転しない排水路8Rとを、例えば接触圧で水密しながら接続する排水連結部36Rを介して排水路8Rに接続されている。排水連結部36Rによって洗濯槽回転軸11Rが回転しても外部には漏水しないようになっている。また排水路8Rの途上に図示しない排水弁が設けられ、排水弁の開閉で洗濯槽89R内に貯水するか、洗濯槽89Rから排水するかの制御が行われる。洗濯槽89Rの上部の開口部には、筐体2Rから伸びた筒状のカバー4Rが、差し込まれるように設けられている。
以下に、本発明に関連する発明にかかる実施例9の洗濯機について説明する。本実施例9の洗濯機は、実施例5の洗濯機と基本的な構成は同じであるが、伝達ベルトの形状及び撹拌翼の数が異なっている。そのため、本相違点を中心に説明する。図21は、本発明に関連する発明にかかる実施例9における洗濯機109Rの底部を下方から視た要部平面図である。上述した実施例5では、撹拌翼駆動軸37Rから2つの回転輪40Rへそれぞれの伝達ベルト38Rによって2つの撹拌翼17Rへ回転駆動力が伝達するように構成されており、撹拌翼駆動軸37Rに軸方向に異なる位置で2つの伝達ベルト38Rが架かるようになっていたが、本実施例9では、1つの伝達ベルト138Rで複数(図21では4個としているが、他の数であっても良い。)の回転輪40Rすなわち撹拌翼17Rを回転するように構成したものである。このように構成すると、実施例5と同様な効果を奏する上、伝達ベルト138Rが撹拌翼駆動軸37Rの1箇所に架かるだけであるので、撹拌翼駆動軸37Rの伝達ベルト138Rが架かる部分の軸方向の長さを短くでき、外槽5Rと洗濯槽9Rとの間の軸方向の空間を最小限とできるため、省スペース化が図れ、その分節水となる。またより多くの撹拌翼17Rを備えることが容易となる。
以下に、本発明に関連する発明にかかる実施例10の洗濯機について説明する。本実施例10の洗濯機は、実施例4の洗濯機と基本的な構成は同じであるが、転動輪が洗濯槽内に配置されている点が異なっている。そのため、本相違点を中心に説明する。図22は、本実施例10に係る洗濯機110Rの側面側から視た構成図であり、図23は洗濯機110Rの撹拌翼117Rを示す要部平面図である。上記実施例4では、洗濯槽9Rの外側で、本発明に関連する発明の転動部の一例である転動輪49Rが、本発明に関連する発明の接触部材の一例を兼ねた駆動軸44Rに直接接触して転動することで、撹拌翼17Rを回転するように構成したものを示したが、本実施例10の洗濯機110Rは、洗濯槽9Rの内側に設けられた撹拌翼117Rの下側部分である転動輪119Rが、駆動軸45Rの上端部に取り付けられた円盤状の撹拌翼駆動体41Rに接触して転動することで撹拌翼117Rが回転する構成となっている。転動輪119Rと撹拌翼117Rとは一体で形成されたものでも良いし、転動輪119Rの表面に放射状の部材を取り付けて撹拌翼117Rを形成するようにしても良い。図22、及び図23に示すように、本実施例10の撹拌翼117Rは、円盤状の転動輪119Rと、その上面に回転の中心から外周に向かって放射状に形成された複数本の撹拌翼翼部43Rとを有している。又、撹拌翼駆動体41Rも、転動輪119Rと外周部で接触するために、厚みのある円盤体であり、上面に中心から外周に向かって放射状に形成された複数本の底部撹拌翼翼部31aRを有している。さらに、転動輪19R及び撹拌翼駆動体41Rは、洗濯槽9Rの曲面形状に沿って、回転する中心部分が凹部となった曲面形状となっている。尚、本発明の転動部の一例は、本実施例の転動輪119Rに相当し、本発明に関連する発明の駆動軸に設けられた円盤状の部材の一例は、本実施例の撹拌翼駆動体41Rに相当する。又、本発明に関連する発明の「洗濯槽を回転させるための洗濯槽用動力発生部と兼ねられている駆動用動力発生部」の一例は、本実施例のモータ12Rに相当し、本発明に関連する発明の洗濯槽自転軸の内側に設けられた駆動軸の一例は、本実施例の駆動軸45Rに相当する。又、駆動軸45Rから撹拌翼117Rに伝達される力が、本発明に関連する発明の洗濯槽が自転する回転力以外の力の一例に相当する。撹拌翼駆動体41Rは駆動軸45Rの上端部に固定され、撹拌翼駆動体41Rの外周部が洗濯槽9R内に2つ備えられた転動輪119Rに接触しており、駆動軸45Rが回転することで、撹拌翼駆動体41Rの外周上を転動輪119Rが転動して、転動輪119Rを有する撹拌翼117Rが回転軸18Rの軸線Mを中心に回転する。なお、駆動軸45Rと撹拌翼117Rの回転数比は撹拌翼駆動体41Rと転動輪19Rとの外径比に比例し、この外径比を変更することで撹拌翼117Rの回転数を簡単に変更選定できる。又、上記実施例4では、撹拌翼117Rを回転するための駆動軸44Rが中空に形成され、内側に洗濯槽9Rを回転するための洗濯槽回転軸11Rが設けられた2重構造で構成されていたが、本実施例10では、上端部が洗濯槽9Rに固定されている洗濯槽回転軸11Rが中空で形成され、内側には駆動軸45Rが設けられた2重構造となっている。回転切換部30Rによって、モータ12Rの回転が、駆動軸45Rを回転するか、洗濯槽回転軸11Rを回転するか、洗濯槽回転軸11Rと駆動軸45Rとを同時に回転するか、などの回転パターンを切り換えられるようになっている。このような回転可能な洗濯槽の底部に洗濯槽回転軸と同軸上に回転可能な底部撹拌翼を備えた構成は、洗濯槽や底部撹拌翼を駆動する機構として、特許文献1や実施例7で示した洗濯機の構成と同様のものである。
以下に、本発明に関連する発明にかかる実施例11の洗濯機について説明する。本実施例11の洗濯機は、実施例10の洗濯機と基本的な構成は同じであるが、洗濯槽の形状が実施例7と同様の円筒形状であり、撹拌翼駆動体41Rが設けられていない点が異なっている。そのため、本相違点を中心に説明する。図25は、実施例11に係る洗濯機111Rの底部近傍を側面側から視た要部構成図であり、図26は、洗濯機111Rの洗濯槽79Rの底部分を示す要部の平面図である。尚、図25は、図26のRST断面模式図である。本実施例11は、実施例10と同様に、洗濯槽79Rの内側で、転動輪139が、本発明に関連する発明の接触部材に接触することによって転動させて撹拌翼137Rが自転するようにした構成であるが、撹拌翼駆動体41Rが設けられておらず、撹拌翼137Rが実施例10の撹拌翼117Rと異なり湾曲していない。上記実施例10では、洗濯槽9Rの底部を半球面状に形成して、洗濯槽回転軸11Rの軸線Lに対して傾斜した回転軸18Rの軸線M廻りに回転する撹拌翼117Rを設けたが、本実施例11は、洗濯槽79Rの底面を平面状に形成し、洗濯槽回転軸11Rの軸線Lに平行な回転軸18Rの軸線M廻りに回転する撹拌翼137Rが3箇所設けられている。また、実施例10のように撹拌翼駆動体41Rは設けずに、転動輪139が駆動軸44Rに直接接触して転動するようにした。尚、本発明に関連する発明の洗濯槽自転軸の内側に設けられ、接触部材を兼ねた駆動軸の一例は、本実施例の駆動軸44Rに相当し、本発明に関連する発明の転動部の一例は、本実施例の転動輪139に相当する。このような構成により、本実施例11では、洗濯槽79Rが自転する洗濯槽回転軸11Rの回転力とともに、駆動軸44Rの回転力によっても、撹拌翼137Rが自転することになる。他の点については実施例10と同様で、実施例10と同様な効果が得られる上、撹拌翼137Rの外径を実施例10より大きくして、洗濯槽79Rの底面の広い範囲で有効に撹拌できるように撹拌翼137Rを配置し易くなり、撹拌効果がより高くなる。また実施例3の変形例における図15(b)のように構成して、洗濯槽回転軸11R(図15(b)の外軸側のレール回転軸27Rに相当する)と駆動軸44R(図15(b)の内軸側の洗濯槽回転軸11Rに相当する)の回転数や回転方向を個別に自在に回転可能にしてもよい。
以下に、本発明に関連する発明にかかる実施例12の洗濯機について説明する。本実施例12の洗濯機は、実施例11の洗濯機と基本的な構成は同じであるが、撹拌翼を回転させる構成が異なっている。そのため、本相違点を中心に説明する。図27は、実施例12に係る洗濯機112Rの底部近傍を側面側から視た要部構成図であり、図28は洗濯機112Rの洗濯槽9Rの底部分を示す要部の平面図である。尚、図27は、図28のRST断面模式図である。実施例11では、駆動軸44Rと転動輪139Rの外径比の関係で、本発明に関連する発明の接触部材の一例である駆動軸44Rをより高速に回転しなければならず、撹拌翼137Rを高速回転することに難点がある。本実施例12では、実施例10のように駆動軸45Rの上端部に、本発明の駆動軸に設けられた円盤状の部材の一例である撹拌翼駆動体41Rを設けて、転動輪129Rが撹拌翼駆動体41Rに接触して転動するようにし、また、実施例10および11では、撹拌翼117R、137Rの回転外周と同じ外径の転動輪119R、139Rとしていたが、本実施例12では、撹拌翼127Rの回転外周より小径の転動輪129Rとした。このようにすることで、実施例10と同様な効果を奏する上、駆動軸45Rを必要以上に高速回転することなく、撹拌翼127Rを高速回転できるようになる。このように、本実施例12では、洗濯槽159Rが自転する洗濯槽回転軸11Rの回転力とともに、駆動軸45Rの回転力によっても、撹拌翼117Rが自転することになる。また、上記実施例10および11では洗濯槽9R、79Rの内側に転動輪119R、139Rが突出しているため、隣接する転動輪119R、139Rや駆動軸44Rの間に洗濯物が噛み込む可能性があった。本実施例12では、転動輪129Rおよび撹拌翼駆動体41Rの形状に沿わせて、底部を窪ませた底部凹部42Rが形成された洗濯槽159Rが設けられ、転動輪129Rおよび撹拌翼駆動体41Rが底部凹部42R内に納まるように構成されている。このようにすることで、実施例10および11と同様な効果を奏する上、洗濯物の噛み込みを抑制することができる。
本発明に関連する発明は、次のように要約される。課題は、撹拌力を向上することが可能な洗濯機を提供することである。その要旨は、内側に洗濯物が収納され、自転可能に設けられた洗濯槽9Rと、洗濯槽9Rに設けられ、洗濯槽の自転の軸となる洗濯槽回転軸11Rと、洗濯槽9Rの内側に自転可能に設けられ、洗濯槽9R内の洗濯物を水と共に撹拌する撹拌翼17Rと、撹拌翼17Rに設けられ、撹拌翼17Rの自転の軸となる撹拌翼自転軸18Rとを備え、撹拌翼自転軸18Rは、洗濯槽自転軸18Rと異なる線上に配置されている、洗濯機101Rである。典型図は図13である。
