Description

滚筒洗衣机 技术领域
本发明涉及一种滚筒洗衣机。该滚筒洗衣机既可以从洗涤到烘干连续地进行，也可以进行洗涤但不进行烘干。
背景技术
以往，滚筒洗衣机在底部存积了水的外槽内使横轴型的滚筒旋转，并通过设置在滚筒内的提升筋将洗涤物举起并使其落下，通过将洗涤物摔到滚筒的内周面来洗涤洗涤物。
这样，在通过提升筋搅拌洗涤物的结构中，洗涤物彼此之间很难互相缠绕或互相摩擦。因此，滚筒洗衣机与在洗涤脱水槽内使搅拌器旋转来洗涤洗涤物的全自动洗衣机相比，作用于洗涤物的机械力容易变小，去污性能容易降低。
因此，在滚筒洗衣机中，为了提高去污性能，可以采用在滚筒的端部设置在表面具有突状部的旋转体，在洗涤、漂洗时，使滚筒和旋转体以不同的旋转速度旋转的结构。在该滚筒洗衣机中，为了使洗涤物恰当地脱水，在脱水时，滚筒和旋转体以相同的旋转速度进行旋转。
使滚筒和旋转体进行旋转的驱动部能设为，具备例如滚筒用的驱动电机和旋转体用的驱动电机，通过带和带将滚筒用的驱动电机的旋转传递给滚筒的旋转轴使滚筒进行旋转，并且通过带和带将旋转体用的驱动电机的旋转传递给旋转体的旋转轴从而使旋转体旋转的结构(参照专利文献1)。

发明内容
发明要解决的问题
将驱动部设为如上所述的结构的情况下，由于通过使用带和带轮的减速机构的简单结构，能使滚筒和旋转体产生旋转速度差，因而与使用齿轮的减速机构的情况相比，在故障等方面上可靠性高。然而，由于为了使滚筒和旋转体进 行旋转而使用了两个驱动电机，因而难以低价地构成驱动部。
此外，如上所述，在脱水时，需要使滚筒和旋转体以相同的旋转速度一体地进行旋转，但是在上述的结构中，在滚筒和旋转体受到来自洗涤物等的不同大小的负载时，在两个驱动电机的旋转速度上可能会产生差值。这样的话，滚筒和旋转体会以不同的旋转速度进行旋转，可能会导致无法进行恰当的脱水。
本发明是鉴于该问题而完成的，其目的在于，提供一种滚筒洗衣机，能通过采用低价并且可靠度高的驱动部使滚筒和旋转体进行旋转。
用于解决问题的方案
本发明的主要方式所涉及的滚筒洗衣机，具备：外槽，配置在壳体内；滚筒，配置在所述外槽内，并且能以水平轴或相对于水平方向倾斜的倾斜轴为中心进行旋转；旋转体，配置在所述滚筒的后部，在表面具有与洗涤物相接触的突状部；以及驱动部，使所述滚筒和所述旋转体进行旋转。此处，所述驱动部包括：驱动电机；第一旋转轴，固定在所述滚筒上；第二旋转轴，固定在所述旋转体上；第一带轮，固定在所述第一旋转轴和所述第二旋转轴中的一方的旋转轴上，经由第一传动带与所述驱动电机相连结；第二带轮，经由第二传动带与所述驱动电机相连结，与所述第一带轮的外径不同；离合器机构部，在第一驱动形态和第二驱动形态之间切换所述驱动部的驱动形态，其中，所述第一驱动形态是指，通过以能够使所述第二带轮的旋转传递至所述第一旋转轴和所述第二旋转轴中的另一方的旋转轴的方式连结所述另一方的旋转轴和所述第二带轮，使所述滚筒和所述旋转体以相互不同的旋转速度旋转；所述第二驱动形态是指，通过以能使所述第一带轮的旋转传递至所述另一方的旋转轴的方式连结所述另一方的旋转轴和所述第一带轮，使所述滚筒旋转和所述旋转体以相同的旋转速度旋转。
根据上述的结构，由于通过使用带和带轮的减速机构的简单结构，能使滚筒和旋转体产生旋转速度差，因而与使用齿轮的减速机构的情况相比，在故障等方面上，能提高驱动部的可靠性。并且，由于能用一个驱动电机使滚筒和旋转体进行旋转，因而能低价地构成驱动部，并且在第二驱动形态中，即使产生滚筒和旋转体受到来自洗涤物等的不同大小的负载的情况，滚筒和旋转体也难以以不同的旋转速度进行旋转，从而不易产生妨碍恰当的脱水的情况。
在本方式的滚筒洗衣机中，所述第二旋转轴内包于所述第一旋转轴中，可以设为与所述第一旋转轴同轴地进行旋转的结构。此外，所述第一带轮和所述 第二带轮可以设为以在所述第一旋转轴和所述第二旋转轴的轴线方向并排的方式配置的结构。这时，所述离合器机构部设为包括：离合器部，配置于所述第一带轮和所述第二带轮之间，能相对于所述另一方的旋转轴向所述轴线方向移动并且能与所述另一方的旋转轴一同进行旋转；以及移动机构部，使所述离合器部向所述轴线方向移动的结构。在所述离合器部的所述第一带轮侧的部位和所述第二带轮侧的部位，分别设置第一卡合部和第二卡合部，并且在所述第一带轮和所述第二带轮上，分别设置第一被卡合部和第二被卡合部。在所述第一驱动形态中，成为所述离合器部通过所述移动机构部向所述第二带轮一侧移动从而所述第二卡合部与所述第二被卡合部卡合，所述第二带轮的旋转经由所述离合器部传递给所述另一方的旋转轴的状态，在所述第二驱动形态中，所述离合器部通过所述移动机构部向所述第一带轮一侧移动从而所述第一卡合部与所述第一被卡合部卡合，所述第一带轮的旋转经由所述离合器部传递给所述另一方的旋转轴的状态。
根据上述的结构，能实现离合器机构部，该离合器机构部在使驱动部采用使用带和带轮的减速机构的结构的情况下，通过配置于第一带轮和第二带轮之间的离合器部和使该离合器部进行移动的移动机构部，能将驱动部的驱动形态在第一驱动形态和第二驱动形态之间良好地切换。
在设为上述的结构的情况下，进而，所述离合器机构部设为包括所述离合器部以自由旋转的方式包围所述离合器部的包围部的结构。在这种情况下，所述移动机构部与所述包围部相连结。
采用这样的结构的话，由于设置不进行旋转的包围部，并且在包围部连结有移动机构部，因而使用不旋转的移动机构部将旋转的离合器部向轴线方向移动。
在采用上述的结构的情况下，进而，所述驱动部可以设为在所述第一带轮和所述第二带轮中，在前侧的带轮的前方，具备自由旋转地支承所述第一旋转轴的轴承部的结构。在这种情况下，在所述前侧的带轮的所述轴承部一侧，形成***述轴承部的至少一部分的凹部。
如果采用这样的结构的话，由于在驱动部的前后方向上，轴承部和前侧的带相重叠，因而能缩小驱动部的前后方向的尺寸。由此，因为能使外槽以及滚筒在前后方向上增大，所以能增多洗涤容量。
在本方式的滚筒洗衣机中，所述第二带轮可以设为自由旋转地支承所述另 一方的旋转轴的结构。
第二带轮在即使是没有与另一方的旋转轴相连结时，也能伴随着驱动电机的旋转而进行旋转。如果采用上述的结构的话，为了实现该旋转从而另一方的旋转轴作为自由旋转地支承第二带轮的支轴而兼用。因此，由于不需要另外设置支轴，因而能减少成本，并且在设置支轴的情况下所需的与另一方的旋转轴之间的轴对准就不需要了，使得驱动部的组装操作变得容易。
在本方式的滚筒洗衣机中，所述第一带轮可以固定在所述第一旋转轴上。此外，所述驱动部的驱动形态可以包括使所述滚筒进行旋转并且使所述旋转体为旋转自由的状态的第三驱动形态。在这种情况下，所述离合器机构部在所述第三驱动形态下，使所述第二旋转轴不与所述第一带轮和所述第二带轮的任意一个连结。
根据上述的结构，可以进行例如在洗涤过程或漂洗过程中向第三驱动形态的切换。在外槽内存积了水的状态下，当驱动电机进行旋转时，滚筒进行旋转，从而通过提升筋搅拌洗涤物。
此时，由于在滚筒的后侧，容易成为洗涤物被旋转体按压的状态，旋转体处于能自由旋转的状态，因而在洗涤物由提升筋搅拌时旋转体也容易和洗涤物一同进行旋转。由此，即使在滚筒的后侧洗涤物也不会产生不易旋转的情况，从而洗涤物进行与滚筒的前侧相同的旋转动作。因而，在滚筒的前侧和后侧不易产生洗涤物的旋转差，从而不易产生因旋转差而导致的洗涤物的扭结。
此外，在第三驱动形态中，由于旋转体不会像第一驱动形态那样通过驱动电机进行旋转，因而也不会因旋转体而产生洗涤物摩擦。
由此，采用上述的结构，能通过利用第三驱动形态进出洗涤、漂洗，使得不易产生因对洗涤物的扭结而产生的损伤、因摩擦而产生的损伤，可以抑制纤弱的衣服产生损伤的同时进行清洗和漂洗。

在壳体10内，外槽20由多个减振器21弹性地支承。滚筒22自由旋转地配置于外槽20内。外槽20以及滚筒22以后表面侧相对于水平方向变低的方式倾斜。由此，滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转。外槽20以及滚筒22的倾斜角度设定为10～20度左右。外槽20的前表面的开口部20a以及滚筒22的前表面的开口部22a与投入口11对置，并与投入口11一起由门12来关闭。在滚筒22的内周面上，形成有许多个脱水孔22b。进而，在滚筒22的内周面上，在圆周方向上以大致相等的间隔设有三个提升筋23。
旋转体24自由旋转地配置于滚筒22的后部。旋转体24具有大致圆盘形状。在旋转体24的表面上，形成有从中央部放射状延伸的多个突状部24a。旋转体24与滚筒22同轴旋转。
在外槽20的后方，配置有产生驱动滚筒22和旋转体24的转矩的驱动部30。驱动部30在洗涤过程和漂洗过程时，使滚筒22和旋转体24在同一方向上以不同的旋转速度进行旋转。
具体地说，驱动部30使滚筒22以施加到滚筒22内的洗涤物的离心力变得比重力小的旋转速度进行旋转，使旋转体24以比滚筒22的旋转速度更快的旋转速度进行旋转。
另一方面，驱动部30在脱水过程时，使滚筒22和旋转体24以施加到滚筒22内的洗涤物的离心力变得远远大于重力的旋转速度一体地进行旋转。驱动部30的详细的结构在后表面进行说明。
在外槽20的底部形成有排水口部20b。在排水口部20b中设置排水阀。排水阀40与排水软管41连接。当排水阀40打开时，存积于外槽20内的水就会通过排水软管41向机外排出。

驱动电机100产生用于驱动滚筒22和旋转体24的转矩。驱动电机100是例如外转子型DC无刷电机，在壳体110内与转子连接的电机轴120从壳体110向后方延伸。
第一旋转轴200具有中空形状。在第一旋转轴200的内部、前部以及后部，分别设置第一滑动轴承211和第二滑动轴承212，在前端部设置机械轴封213。
第二旋转轴300内包于第一旋转轴200。第二旋转轴300的前部从第一旋转轴200向前方突出，第二旋转轴300的后部从第一旋转轴200向后方突出。第二旋转轴300的外周面由第一滑动轴承211和第二滑动轴承212支撑，在第一旋转轴200内顺利地进行旋转。此外，通过机械轴封213能防止水向第二旋转轴300和第一旋转轴200之间侵入。
在轴承单元400中，在中央部设置大致圆筒状的轴承部410。在轴承部410的内部，在前部以及后部上，分别设置第一滚动轴承411和第二滚动轴承412，在前端部设置机械轴封413。第一旋转轴200的外周面由第一滚动轴承411和第二滚动轴承412支撑，在轴承部410内顺利地进行旋转。此外，通过机械轴封413能防止水向第一旋转轴200和轴承部410之间侵入。进而，在轴承单元400上，在轴承部410的周围形成固定凸缘部420。
在固定凸缘部420中，通过紧固螺钉等的固定方法，将轴承单元400固定在外槽20的后表面。在轴承单元400已安装于外槽20内的状态下，第二旋转轴300和第一旋转轴200面临外槽20的内部。滚筒22通过未图示的螺钉固定在第一旋转轴200中，旋转体24通过螺钉310固定在第二旋转轴300中。
翼减速机构500包括翼带轮510、第一电机带轮520、以及翼传动带530。驱动电机100的旋转根据由翼带轮510和第一电机带轮520的外径比决定的减速比减速，并传递给第二旋转轴300。
翼带轮510通过第二旋转轴300的后端部被自由旋转地支承。在翼带轮510上，在中央部形成***第二旋转轴300的***孔511，在该***孔511和第二旋转轴300之间夹有前后两个滚动轴承512、513。翼带轮510通过两个滚动轴承512、513，相对于第二旋转轴300顺利地进行旋转。
如图4(a)所示，在翼带轮510的前表面上形成环状的被卡合凹部514。在被卡合凹部514的外周面上遍及整周地形成齿条515。齿条515相当于本发明的第二被卡合部。通过安装于第二旋转轴300的后端部的固定螺钉320，能防止翼带轮510向后方脱落。
第一电机带轮520安装于驱动电机100的电机轴120的前端部。翼传动带530架设在翼带轮510和第一电机带轮520之间。
滚筒减速机构600包括滚筒带轮610、第二电机带轮620、以及滚筒传动带 630。驱动电机100的旋转根据由滚筒带轮610和第二电机带轮620的外径比决定的减速比减速，并传递给第一旋转轴200。
滚筒带轮610形成为前表面打开的盘状，包括带部611和比带部611外径小的固定部612。带部611的外径，即滚筒带轮610的外径由于比翼带轮510的外径大，所以滚筒减速机构600的减速比比翼减速机构500的减速比更大。
在固定部612上，在中央部形成***孔613。第一旋转轴200的后端部***到***孔613中，第一旋转轴200的后端部通过使用齿条的压入等规定的固定方法固定于***孔613中。由此，滚筒带轮610固定在第一旋转轴200的后端部上。
如图4(b)所示，在固定部612的后表面上，在***孔613的外圆周形成环状的被卡合凹部614。在被卡合凹部614的外周面形成遍及整周的齿条615。齿条615相当于本发明的第一被卡合部。
在向后方凹陷的凹部616的带部611的内部收容有轴承部410的后端部。由此，在驱动部30的前后方向上，轴承单元400和滚筒带轮610相重叠。
第二电机带轮620安装于驱动电机100的电机轴120的基部。滚筒传动带630架设于滚筒带轮610和第二电机带轮620之间。
此外，滚筒带轮610相当于本发明的第一传动带，滚筒传动带630相当于本发明的第一传动带。此外，翼带轮510相当于本发明的第二传动带，翼传动带530相当于本发明的第二传动带。
离合器机构部700使驱动部30的驱动形态在二轴驱动形态和一轴驱动形态之间切换，所述二轴驱动形态，是通过连结第二旋转轴300和翼带轮510使翼带轮510的旋转可以传递给第二旋转轴300，使得滚筒22和旋转体24以相互不同的旋转速度进行旋转的形态，所述一轴驱动形态，是通过连结第二旋转轴300和滚筒带轮610使滚筒带轮610的旋转可以传递给第二旋转轴300，使得滚筒22和旋转体24以相同的旋转速度进行旋转的形态。二轴驱动形态相当于本发明的第一驱动形态，一轴驱动形态相当于本发明的第二驱动形态。
离合器机构部700包括离合器引导710、离合器体720、离合器杆730、杆支承部740、以及离合器驱动装置750。
离合器引导710和离合器体720配置于在第一旋转轴200和第二旋转轴300的轴线方向上排列的滚筒带轮610和翼带轮510之间。
如图5所示，离合器引导710具有前表面打开的圆筒形状。在离合器引导 710的外周面上，在整个面上形成遍及整周的齿条711。在离合器引导710的中央部，形成***孔712。在***孔712上，形成键槽713。离合器引导710的***孔712穿过第二旋转轴300，通过使用键槽713和未图示的键的固定方法固定于第二旋转轴300。由此，离合器引导710与第二旋转轴300一同进行旋转。
如图5(a)所示，离合器体720包括离合器部721、包围部722、以及滚动轴承723。离合器部721具有前表面和后表面打开的圆筒形状。如图6所示，在离合器部721的外周面上，在前部和后部分别形成遍及整周的前齿条724和后齿条725。前齿条724相当于本发明的第一卡合部，后齿条725相当于本发明的第二卡合部。
离合器部721的内径大致与离合器引导710的外径相等，离合器部721的前后的尺寸设为比离合器引导710的前后的尺寸更大。在离合器部721的内部***有离合器引导710。在离合器部721的内周面上形成遍及整周的内齿条726，该内齿条726与离合器引导710的齿条711咬合。内齿条726的前后的尺寸设为比齿条711的前后的尺寸更大。
通过使内齿条726和齿条711卡合，离合器部721能相对于离合器引导710，即固定有离合器引导710的第二旋转轴300向第二旋转轴300的轴线方向移动并且成为能与第二旋转轴300一同旋转的状态。
包围部722形成为圆环状，以离合器部721自由旋转的方式包围离合器部721的中央部。在离合器部721和包围部722之间，设置滚动轴承723。滚动轴承723通过大小两个扣环727、728固定从而无法向前后活动。离合器部721通过滚动轴承723相对于包围部722顺利地旋转。
离合器杆730的上端部相对于包围部722可旋转地与包围部722连结。此外，离合器杆730可转动地支承于杆支承部740上设置的支轴741上。
离合器驱动装置750包括促动器751和操作杆752。促动器751使操作杆752向前后移动。操作杆752与离合器杆730的下端部连结。离合器杆730的下端部可以相对于操作杆752进行旋转。
杆支承部740和离合器驱动装置750固定于为图示的安装板上，该安装板安装于轴承单元400、或者外槽20上。
此外，离合器杆730、杆支承部740以及离合器驱动装置750构成发明的移动机构部。
在驱动部30的驱动形态从一轴驱动形态被切换到二轴驱动形态的情况下， 如图2所示，操作杆752从促动器751的内部推出到前方。离合器杆730的下端部***作杆752推动向前方移动，离合器杆730以支轴741为中心向后方进行旋转。离合器杆730的上端部向后方进行移动，离合器体720被离合器杆730的上端部推动向后方进行移动。由此，离合器部721的后齿条725和翼带轮510的齿条515卡合。
当后齿条725和齿条515卡合时，由于离合器部721和翼带轮510在旋转方向上被固定，所以成为能将翼带轮510的旋转经由离合器部721和离合器引导710传递给第二旋转轴300。在这样的状态下，当驱动电机100进行旋转时，该旋转经由翼减速机构500传递给第二旋转轴300，固定于第二旋转轴300的旋转体24进行旋转。旋转体24以驱动电机100的旋转速度根据翼减速机构500的减速比降低后的旋转速度进行旋转。此外，驱动电机100的旋转经由滚筒减速机构600传递给第一旋转轴200，固定于第一旋转轴200的滚筒22进行旋转。滚筒22以驱动电机100的旋转速度根据滚筒减速机构600的减速比降低后的旋转速度进行旋转。如上所述，由于滚筒减速机构600的减速比比翼减速机构500的减速比更大，所以旋转体24以比滚筒22快的旋转速度向与滚筒22相同的方向进行旋转。
此处，虽然离合器部721与翼带轮510一同进行旋转，但是由于离合器杆730与以自由旋转的状态连结离合器部721的包围部722连结，因而即使离合器部721进行旋转，其旋转几乎不会传递给离合器杆730。
另一方面，在驱动部30的驱动形态从二轴驱动形态被切换为一轴驱动形态的情况下，如图3所示，操作杆752被拉入到促动器751的内部。即操作杆752向后方进行移动。离合器杆730的下端部***作杆752拉动向后方进行移动，离合器杆730以支轴741为中心向前方进行旋转。离合器杆730的上端部向前方进行移动，离合器体720被离合器杆730的上端部推动向前方进行移动。由此，离合器部721的前齿条724和滚筒带轮610的齿条615卡合。
当前齿条724和齿条615卡合时，由于离合器部721和滚筒带轮610在旋转方向上被固定，因而成为能将滚筒带轮610的旋转经由离合器部721和离合器引导710传递给第二旋转轴300的状态。在这样的状态下，当驱动电机100进行旋转时，该旋转经由滚筒减速机构600传递给第一旋转轴200和第二旋转轴300，从而滚筒22和旋转体24进行旋转。滚筒22和旋转体24以驱动电机100的旋转速度根据滚筒减速机构600的减速比降低后的旋转速度向相同的方向 一体地进行旋转。
此外，在一轴驱动形态中，当驱动电机100进行旋转时，翼带轮510也伴随着该旋转而进行旋转。但是，翼带轮510仅仅相对于第二旋转轴300进行空转，翼带轮510的旋转不会传递给第二旋转轴300。
然后，滚筒洗衣机1进行各种运转模式的洗涤运转。洗涤运转包括洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。
在洗涤过程和漂洗过程中，驱动部30的驱动形态被切换为二轴驱动形态。在外槽20内存积了没有到投入口11的下边缘的规定水位的水的状态下，驱动电机100交互地进行右旋转和左旋转。由此，滚筒22和旋转体24以旋转体24的旋转速度比滚筒22的旋转速度快的状态，交互地进行右旋转和左旋转。此时，滚筒22的旋转速度设定为作用于滚筒22内的洗涤物的离心力变得比重力小的旋转速度。
当滚筒22和旋转体24进行旋转时，通过提升筋23将滚筒22内的洗涤物举起并使其落下，从而摔到滚筒22的内周面上。除此之外，在滚筒22的后部，洗涤物与旋转的旋转体24的突状部24a接触，洗涤物被突状部24a摩擦，通过突状部24a洗涤物被进行搅拌。由此，洗涤物被清洗或漂洗。
这样，在洗涤和漂洗时，由于不仅是滚筒22的旋转产生的机械力，旋转体24产生的机械力也被付与到洗涤物上，从而能期待去污性能的提高。接着，在中间脱水过程和最终脱水过程中，驱动部30的驱动形态被切换为一轴驱动形态。驱动电机100向一个方向高速地进行旋转，滚筒22和旋转体24以作用于滚筒22内的洗涤物的离心力远远大于重力的旋转速度一体地进行旋转。通过离心力的作用，洗涤物被摔到滚筒22的内周面上进行脱水。
这样，在脱水时，由于滚筒22和旋转体24一体地进行旋转，因而贴附在滚筒22的洗涤物不用通过旋转体24进行搅拌就能将洗涤物良好地脱水。
<实施方式的效果>
根据本实施方式，由于通过使用带和带轮的减速机构的简单结构，能使滚筒22和旋转体24产生旋转速度差，因而与使用齿轮的减速机构的情况相比，在故障等方面上，能提高驱动部30的可靠性。并且，由于能用一个驱动电机100使滚筒22和旋转体24进行旋转，因而能低价地构成驱动部30，并且在第二驱动形态中，即使产生滚筒22和旋转体24受到来自洗涤物等的不同大小的负载的情况，滚筒22和旋转体24也难以以不同的旋转速度进行旋转，从而不易产 生妨碍恰当的脱水的情况。
进而，根据本实施方式，能实现离合器机构部700，该离合器机构部700在使驱动部30采用使用带和带轮的减速机构的结构的情况下，通过配置于滚筒带轮610和翼带轮510之间的离合器体720和使该离合器体720进行移动的离合器杆730和离合器驱动装置750，能将驱动部30的驱动形态在二轴驱动形态和一轴驱动形态之间良好地切换。
进而，根据本实施方式，由于设置以自由旋转的状态包围离合器部721的包围部722，并且设为该包围部722与离合器杆730连结，因而使用不旋转的移动机构部将旋转的离合器部721向第二旋转轴300的轴线方向移动。
进而，根据本实施方式，由于在驱动部30的前后方向上，轴承单元400和滚筒带轮610相重叠，因而能缩小驱动部30的前后方向的尺寸。由此，因为能使外槽20以及滚筒22在前后方向上增大，所以能增多洗涤容量。
进而，根据本实施方式，在一轴驱动形态中为了使翼带轮510进行旋转所需要的，第二旋转轴300作为自由旋转地支承翼带轮510的支轴而兼用。由此，因为不需要另外设置支轴，所以能减少成本，并且在设置支轴的情况下所需的与第二旋转轴300之间的轴对准就不需要了，使得驱动部30的组装操作变得容易。
<变更例1>
在上述实施方式中，驱动部30的驱动形态在使滚筒22和旋转体24以相互不同的旋转速度进行旋转的二轴驱动形态和使滚筒22和旋转体24以相同的旋转速度进行一体旋转的一轴驱动形态之间进行切换。
相对于此，在本变更例中，不仅能将驱动部30的驱动形态切换为二轴驱动形态和一轴驱动形态，还能切换为使滚筒22进行旋转的同时使旋转体24为旋转自由的状态的滚筒单体驱动形态。滚筒单体驱动形态相当于本发明的第三驱动形态。
图7是表示本变更例所涉及的进行向滚筒单体驱动形态切换的状态的驱动部30的图。
如图7所示，在滚筒单体驱动形态中，前齿条724通过离合器杆730与滚筒带轮610的齿条615不卡合，离合器部721移动到后齿条725也与翼带轮510不卡合的位置上。即，离合器机构部700的第二旋转轴300与滚筒带轮610和翼带轮510的任意一个都不连结。
在这样的状态下，当驱动电机100进行旋转时，虽然滚筒22进行旋转，但是由于带510、610的旋转都没有向第二旋转轴300传递，因而旋转体24不进行旋转。但是，由于第二旋转轴300相对于第一旋转轴200可以旋转，因而旋转体24成为能自由旋转的状态。
例如，在洗涤过程或漂洗过程中，进行向滚筒单体驱动形态切换。在外槽20内存积了水的状态下，当驱动电机100进行旋转时，滚筒22就进行旋转，通过提升筋23对洗涤物进行搅拌。
此时，在滚筒22的前侧，由于洗涤物通过提升筋23被举到滚筒22的正上方附近并落下，因而在滚筒22进行一次旋转之间几乎旋转两次。另一方面，在滚筒22的后侧，洗涤物容易成为被旋转体24按压的状态。如上所述，由于旋转体24处于能自由旋转的状态，因而洗涤物在由提升筋23搅拌进行旋转时旋转体24也容易与洗涤物一同地进行旋转。由此，即使在滚筒22的后侧，也与前侧相同，洗涤物在滚筒22进行一次旋转之间几乎旋转两次。因此，在滚筒22的前侧和后侧不易产生洗涤物的旋转差，从而不易产生因旋转差而导致的洗涤物的扭结。
此外，在旋转体24相对于滚筒22不能自由旋转的情况下，在滚筒22的后侧，当洗涤物被推压到旋转体24时，在由提升筋23进行搅拌时，洗涤物不会落到滚筒22的正上方附近，成为贴附于旋转体24进行旋转的状态。这样的话，在滚筒22的后侧，由于洗涤物在滚筒22进行一次旋转之间几乎只旋转一次，因而在滚筒22的前侧和后侧产生洗涤物的旋转差，从而使洗涤物容易扭结。
此外，在滚筒单体驱动形态中，由于旋转体24不能像二轴驱动形态那样通过驱动电机100进行旋转，因而也不会有洗涤物通过旋转体24被摩擦的情况。
这样，在洗涤过程或者漂洗过程中，在滚筒单体驱动形态下使驱动电机100工作的情况下，不易对洗涤物产生扭结的损伤、摩擦的损伤。因此，根据本变更例，可以抑制纤弱的衣服产生损伤的同时进行清洗和漂洗。
<变更例2>
图8是表示本变更例所涉及的驱动部30的结构的图。图8是驱动部30的后部的放大图。
在上述实施方式中，滚筒带轮610固定于第一旋转轴200的后端部，翼带轮510以相对于第二旋转轴300自由旋转的方式，经由前后两个滚动轴承512、513安装于第二旋转轴300的后端部。进而，离合器引导710固定于第二旋转轴 300上。
相对于此，在本变更例中，如图8所示，翼带轮510A借助使用齿条的压入等的固定方法固定于第二旋转轴300A的后端部。此外，滚筒带轮610A以相对于第一旋转轴200A自由旋转的方式经由前后两个滚动轴承617、618安装于第二旋转轴300A的后端部。进而，离合器引导710A固定于第一旋转轴200A。
在本变更例中，当进行向二轴驱动形态的切换时，如图8所示，离合器部721向滚筒带轮610A一侧进行移动，前齿条724和齿条615卡合。由此，成为将滚筒带轮610A的旋转经由离合器部721和离合器引导710A传递给第一旋转轴200A的状态。在这样的状态下，当驱动电机100进行旋转时，该旋转经由滚筒减速机构600传递给第一旋转轴200A，从而固定于第一旋转轴200A的滚筒22进行旋转。此外，驱动电机100的旋转经由翼减速机构500传递给第二旋转轴300A，从而固定于第二旋转轴300A的旋转体24进行旋转。这样，旋转体24以比滚筒22快的旋转速度向与滚筒22相同的方向进行旋转。
另一方面，当进行向一轴驱动形态的切换时，如图8中用点划线所示的，离合器部721向翼带轮510A一侧进行移动，后齿条725和齿条515卡合。由此，成为将翼带轮510A的旋转经由离合器部721和离合器引导710传递给第一旋转轴200A的状态。在这样的状态下，当驱动电机100进行旋转时，该旋转经由翼减速机构500传递给第一旋转轴200A和第二旋转轴300A，从而滚筒22和旋转体24进行旋转。即，滚筒22和旋转体24以相同的旋转速度一体地向相同的方向进行旋转。
根据本变更例，也能起到和上述实施方式相同的作用效果。
此外，在本变更例中，滚筒带轮610A相当于本发明的第二传动带，滚筒传动带630相当于本发明的第二传动带。此外，翼带轮510A相当于本发明的第一传动带，翼传动带530相当于本发明的第一传动带。
<其它的变更例>
以上，虽然关于本发明的实施方式进行了说明，但是本发明不受上述实施方式等的任何限制，另外，本发明的实施方式也可以进行上述以外的各种变更。
例如，在上述实施方式中，通过离合器部721的前齿条724和滚筒带轮610的齿条615的卡合，离合器部721和滚筒带轮610在旋转方向上被固定。此外，通过离合器部721的后齿条725和翼带轮510的齿条515的卡合，离合器部721和翼带轮510在旋转方向上被固定。但是，将离合器部721的前部与滚筒带轮 610卡合的结构和将离合器部721的后部与翼带轮510卡合的结构，不局限于上述实施方式，也可以为其它结构。可以采用例如在离合器部721的前部和后部形成突起，并且在滚筒带轮610和翼带轮510形成凹陷或孔，突起嵌入到凹陷或孔中的结构。
此外，在上述实施方式中，在翼带轮510和第二旋转轴300之间设置两个滚动轴承512、513。此外，在离合器部721和包围部722之间设置滚动轴承723。然而，这些滚动轴承512、513、723也可以置换为滑动轴承。同样地，上述变更例2的滚动轴承617、618也可以置换为滑动轴承。
进而，在上述实施方式中，滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转。但是，滚筒洗衣机1也可以采用滚筒22以水平轴为中心进行旋转的结构。
进而，虽然上述实施方式的滚筒洗衣机1不具备烘干功能，但本发明也能用于具备烘干功能的滚筒洗衣机，即滚筒式烘干洗衣机。
此外，本发明的实施方式在权利要求书示出的技术思想的范围内可以适当地进行各种变更。
