Description

滚筒洗衣机 技术领域
本发明涉及一种滚筒式洗衣机。该滚筒式洗衣机既可以连续地进行从洗涤到烘干的运转，也可以进行洗涤但不进行烘干。
背景技术
以往，滚筒式洗衣机在蓄水于底部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(baffle)将洗涤物举起且使其落下，通过将洗涤物摔到滚筒的内周面来洗涤洗涤物(参照专利文献1)。
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，滚筒式洗衣机与在洗涤脱水槽内使搅拌器(pulsator)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易变小，去污性能易降低。
因此，在滚筒式洗衣机中，为了提高去污性能，可以采用在滚筒的后面设置搅拌体，在洗涤、漂洗时使滚筒与搅拌体以不同的旋转速度分别旋转的结构。

发明内容
发明所要解决的问题
进行洗涤时，在干燥状态下将洗涤物投入滚筒内的情况较多。在滚筒内收容了很多干燥的洗涤物的情况下，可能会出现洗涤物被压缩在滚筒前表面的门和滚筒后面的搅拌体之间，搅拌体被洗涤物压迫的状态。此外，当洗涤物、搅拌体处于干燥状态时，与处于浸湿状态相比，摩擦系数变大。因此，像这样，在搅拌体被干燥的洗涤物压迫的状态下，当滚筒和搅拌体各自旋转时，会对搅拌体施加来自洗涤物的大的负荷，驱动搅拌体的驱动电机有可能会锁定。
本发明是鉴于上述问题而完成的技术方案，目的在于提供一种滚筒洗衣机，能实现清洗性能的提高并防止驱动部工作不良等故障的产生。
用于解决问题的方案
本发明的主要实施方式的滚筒洗衣机具备：外槽，配置在壳体内；滚筒，配置在所述外槽内，能够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，表面具有与洗涤物接触的突状部；驱动部，使所述滚筒以及所述旋转体以相互不同的旋转速度进行旋转；以及给水机构部，泼水到所述旋转体的表面。
通过上述结构，由给水机构部对旋转体的表面泼水，浸湿旋转体以及与旋转体接触的洗涤物，由此能减少双方的摩擦系数。由此，能减少由于与洗涤物的接触而施加给旋转体的负荷，能够防止驱动部发生电机锁定等故障。
在本方式的滚筒洗衣机中，所述给水机构部可采用包括贮水部和流出口的结构，其中，所述贮水部在浸泡于所述外槽内的水的位置和比所述外槽内的水靠上方的位置之间移动，并在浸泡在所述外槽内的水中时贮留水；所述流出口设置于所述贮水部，处于所述上方的位置，使贮留在所述贮水部中的水流出到所述旋转体的表面。
通过上述结构，能够从贮水部将存积在外槽内的水上汲并泼到旋转体的表面，能够利用外槽内的水浸湿旋转体的表面等。
在采用上述结构的情况下，进一步地，所述贮水部可以采用设置在所述滚筒的后面或内圆周面，通过所述滚筒旋转而移动的结构。
由于采用这样的结构就能够利用滚筒的旋转上汲外槽内的水，因此能够容易地利用外槽内的水。
在采用上述结构的情况下，进一步地，所述给水机构部还可以采用包括设置在所述贮水部并将所述外槽内的水摄入所述贮水部的摄入口的结构。在这种情况下，所述摄入口可以采用在所述滚筒进行旋转时的行进方向侧开口的结构。
由于采用这样的结构时，当贮水部通过滚筒的旋转而没入水中时，水容易经摄入口流入贮水部内，因此容易在贮水部内蓄水。
在所述给水机构部采用包括所述贮水部和所述流出口的结构的情况下，进一步地，可以采用在所述贮水部内设置引导筋的结构，其中，引导筋在水从所述流出口流出时将水引导至所述流出口。
由于采用这样的结构时，能够顺利地将贮水部内的水通过引导筋引导至流出口，因此能够使水很好地从流出口朝着旋转体流出。
在所述给水机构部采用包含所述贮水部和所述流出口的结构的情况下，所述突状部还可以采用下述结构：从所述旋转体的中央部至浸泡在所述外槽内的水中的外圆周部呈放射状延伸，并且，对应表面的突出在背面形成有凹陷部。在这种情况下，所述贮水部构成为包括所述凹陷部，并通过所述旋转体旋转而进行移动，在所述凹陷部设有所述流出口。
由于采用这样的结构时，为了使突状部的壁厚均匀，将必然形成于旋转体的背面的凹陷部用作贮水部，因此能够简单方便地实现给水机构部。并且，由于能够利用旋转体的旋转而上汲到外槽内，因此能够容易地利用外槽内的水。
在所述给水机构部采用包括所述贮水部和所述流出口的结构的情况下，进一步地，可以采用在所述滚筒的内圆周面设有中空的提升筋的结构。在这种情况下，采用所述贮水部包括所述提升筋，并通过所述滚筒旋转而进行移动的结构，在所述提升筋上，所述流出口设置在从该流出口流出的水泼到所述旋转体的表面的位置。
由于采用这样的结构时，为了搅拌洗涤物，将提升筋用作贮水部，因此能够简单方便地实现给水机构部。并且，由于能够利用滚筒的旋转上汲外槽内的水，因此能够容易地利用外槽内的水。

具体实施方式
以下，关于作为本发明的滚筒式洗衣机的一个实施方式的不具有烘干功能 的滚筒式洗衣机，参照附图进行说明。
图1是表示滚筒洗衣机1的结构的侧面剖视图。
滚筒洗衣机1具备构成外形的壳体10。壳体10的前表面形成有洗涤物的投入口11。投入口11由开闭自由的门12覆盖。
外槽20在壳体10内由多个减振器21弹性支承。滚筒22旋转自由地配置于外槽20内。滚筒22以水平轴为中心进行旋转。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来锁闭。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。
在滚筒22的后部，旋转自由地配置有搅拌体24。搅拌体24具有大致圆盘形，与滚筒22同轴旋转。搅拌体24相当于本发明的旋转体。进而，在滚筒22的后部，设有护圈单元25。护圈单元25形成为环状并包含围住搅拌体24的护圈710。护圈710阻止洗涤物被咬入搅拌体24与滚筒22之间产生的间隙。搅拌体24以及护圈单元25的具体结构之后进行说明。
在外槽20的后方，配置有产生驱动滚筒22以及搅拌体24的转矩的驱动单元30。驱动单元30相当于本发明的驱动部。驱动单元30在洗涤工序以及漂洗工序时，使滚筒22以及搅拌体24在同一方向上以不同的旋转速度进行旋转。具体地说，驱动单元30使滚筒22以施加给滚筒22内的洗涤物的离心力小于重力的旋转速度进行旋转，并使搅拌体24以比滚筒22的旋转速度还要快的旋转速度进行旋转。另一方面，驱动单元30在脱水工序时使滚筒22以及搅拌体24以施加给滚筒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。驱动单元30的具体结构之后进行说明。
在外槽20的底部形成有排水口部20b。在排水口部20b中设置有排水阀40。排水阀40与排水软管41连接。当排水阀40打开时，贮存于外槽20内的水就会通过排水软管41向机外排出。
在壳体10内的前方上部，配置有洗涤剂盒50。收容洗涤剂的洗涤剂容器50a从前方自由抽出地收容于洗涤剂盒50中。洗涤剂盒50通过给水软管52与配置在壳体10内的后方上部的给水阀51连接。此外，洗涤剂盒50通过注水管53与外槽20的上部连接。当给水阀51打开时，通过给水软管52、洗涤剂盒50以及注水管53将来自水龙头的自来水供给外槽20内。此时，顺着水流将收容 在洗涤剂容器50a中的洗涤剂供给外槽20内。
接下来，就驱动单元30的结构进行详细说明。
图2以及图3是表示驱动单元30的结构的剖视图。图2表示驱动单元30的驱动形态被切换到二轴驱动形态的状态，图3表示驱动单元30的驱动形态被切换到一轴驱动形态的状态。图4是表示驱动电机100的转子110的结构的转子110的主视图。图5是形成有齿条514的轴承单元500的后部的放大立体图。图6(a)～(c)是表示离合器机构部600的离合器体610的结构的图，其分别为离合器体610的主视图、右视图以及后视图。
驱动单元30包括：驱动电机100、翼轴200、滚筒轴300、行星齿轮机构400、轴承单元500以及离合器机构部600。驱动电机100产生用于驱动搅拌体24以及滚筒22的转矩。翼轴200利用驱动电机100的转矩进行旋转，并将该旋转传递给搅拌体24。行星齿轮机构400将翼轴200的旋转即驱动电机100的转子110的旋转减速并传递给滚筒轴300。滚筒轴300以由行星齿轮机构400减速后的旋转速度与翼轴200同轴旋转，并将该旋转传递给滚筒22。轴承单元500旋转自由地支承翼轴200以及滚筒轴300。离合器机构部600在二轴驱动形态和一轴驱动形态之间切换驱动单元30的驱动形态，其中，所述二轴驱动形态是能使搅拌体24即翼轴200以与驱动电机100的旋转速度相等的旋转速度进行旋转，并使滚筒22即滚筒轴300以由行星齿轮机构40减速后的旋转速度进行旋转的形态，所述一轴驱动形态是能使搅拌体24以及滚筒22即翼轴200、滚筒轴300以及行星齿轮机构400以与驱动电机100相等的旋转速度一体地进行旋转的形态。
驱动电机100是外转子型DC无刷电机，包括转子110和定子120。转子110形成为有底的圆筒状，在其内周面上遍及整个圆周排列有永久磁铁111。如图4所示，在转子110的中央部形成有圆形的轴套部112。在轴套部112中形成有用于固定翼轴200的轴套孔113，并且在轴套孔113的外周上形成有环状的被卡合凹部114。被卡合凹部114的外周部遍及整个圆周具有凹凸部114a。
定子120在外周部具有线圈121。当从后述的电机驱动部给定子120的线圈121供给驱动电流时，转子110进行旋转。
滚筒轴300具有中空形状，并内包翼轴200和行星齿轮机构400。滚筒轴300的中央部向外侧膨出，该膨出的部位构成行星齿轮机构400的收容部。
行星齿轮机构400包括：太阳齿轮410、包围太阳齿轮410的环状的内齿轮420、介于太阳齿轮410和内齿轮420之间的多组行星齿轮430以及自由旋转地保持这些行星齿轮430的行星齿轮架440。
太阳齿轮410固定在翼轴200，内齿轮420固定在滚筒轴300。一组行星齿轮430包括相互咬合且反向进行旋转的第一齿轮和第二齿轮。行星齿轮架440包括向后方延伸的齿轮架轴441。齿轮架轴441与滚筒轴300为同轴，并且内部形成为中空以供翼轴200插入。
翼轴200的后端部从齿轮架轴441向后方突出，并被固定于转子110的轴套孔113。
在轴承单元500中，在中央部设置有圆筒状的轴承部510。在轴承部510的内部，在前部以及后部设有滚轴511、512，在前端部设有机械密封件513。滚筒轴300的外周面由滚轴511、512支承，并在轴承部510内顺滑地旋转。另外，通过机械密封件513防止水侵入轴承部510和滚筒轴300之间。如图5所示，在轴承部510的后端部，在内面上遍及整个圆周形成有齿条514。
在轴承单元500中，在轴承部510的周围形成有固定凸缘部520。在固定凸缘部520的下端部形成有安装轴套521。
轴承单元500在固定凸缘部520处，通过紧固螺钉等的固定方法固定在外槽20的后面。在驱动单元30已安装于外槽20内的状态下，翼轴200以及滚筒轴300面临外槽20的内部。滚筒22固定在滚筒轴300，搅拌体24固定在翼轴200。
离合器机构部600包括：离合器体610、离合器弹簧620、离合器杆630、杆支承部640、离合器驱动装置650、接合棒660、安装板670。
如图6(a)至(c)所示，离合器体610大致具有圆盘形状。在离合器体610的前端部，在外周面上形成有环状的齿条611。齿条611以与轴承单元500的齿条514卡合的方式形成。另外，在离合器体610的外周面上，在齿条611的后方形成有凸缘部612。进而，在离合器体610中，在后端部形成有环状的卡合凸缘部613。卡合凸缘部613具有与转子110的被卡合凹部114相同的形状，在外周部遍及整个圆周具有凹凸部613a。当卡合凸缘部613插入到被卡合凹部114时，凹凸部613a、114a就彼此卡合。
齿轮架轴441插入离合器体610的轴孔614。形成于轴孔614的内周面上的 齿条614a和形成于齿轮架轴441的外周面上的齿条441a卡合。由此，离合器体610成为相对于齿轮架轴441，前后方向上的移动被允许，并且圆周方向上的转动被限制的状态。
在离合器体610中，在轴孔614的外侧形成有环状的收容槽615，在该收容槽615中收容有离合器弹簧620。离合器弹簧620的一端与轴承部510的后端部相接，另一端与收容槽615的底面相接。
在离合器杆630的上端部形成有与离合器体610的凸缘部612的后面接触，并将凸缘部612向前方推的按压部631。离合器杆630由设置于杆支承部640上的支轴641自由转动地支承。在离合器杆630的下端部形成有安装轴632。
离合器驱动装置650配置于离合器杆630的下方。离合器驱动装置650包括转矩电机651和通过转矩电机651的转矩绕着水平轴旋转的圆盘状的凸轮652。在凸轮652的上面，在外周部设有凸轮轴653。凸轮652的旋转中心和离合器杆630的安装轴632的中心在前后方向上一致。
接合棒660向上下方向延伸，并将离合器杆630和凸轮652进行连结。接合棒660的上端部安装于离合器杆630的安装轴632上，下端部安装于凸轮652的凸轮轴653上。在接合棒660的中间位置上一体地形成有弹簧661。弹簧661是拉伸弹簧。
杆支承部640以及离合器驱动装置650通过紧固螺钉等的固定方法固定于安装板670。安装板670通过螺钉固定于轴承单元500的安装轴套521。
在驱动单元30的驱动形态从一轴驱动形态切换到二轴驱动形态的情况下，如图2所示，凸轮652利用转矩电机651进行旋转以使凸轮轴653位于最下方。随着凸轮652进行旋转，离合器杆630的下端部被接合棒660拉到下方。离合器杆630以支轴641为中心向前方旋转，按压部631将离合器体610向前方推。离合器体610逆着离合器弹簧620的弹力向前方移动，离合器体610的齿条611和轴承单元500的齿条514卡合。
当离合器体610的凸轮轴653移动到中间的规定位置时，齿条611到达与齿条514卡合的位置。此时，接合棒660的弹簧661处于自然长度的状态。由于离合器体610不会移动到比该卡合位置更靠前的位置，所以当凸轮轴653从规定位置移动到最下方的位置时，如图2所示，弹簧661伸长到下方。这样，由于离合器杆630以向前方转动的方式被弹簧661拉动，所以从按压部631给 位于卡合位置的离合器体610施加按压力。由此，能使齿条611紧紧地卡合于齿条514。
当齿条611和齿条514卡合时，由于离合器体610相对于轴承单元500在圆周方向上的转动受限，成为不可转动的状态，所以行星齿轮机构400的齿轮架轴441，即行星齿轮架440成为以不能旋转的方式被固定的状态。在这样的状态下，当转子110旋转时，翼轴200以与转子110的旋转速度相等的旋转速度进行旋转，并且与翼轴200连结的搅拌体24也以与转子110的旋转速度相等的旋转速度进行旋转。随着翼轴200的旋转，在行星齿轮机构400中太阳齿轮410进行旋转。如上所述，由于行星齿轮架440处于被固定的状态，所以行星齿轮430的第一齿轮以及第二齿轮分别与太阳齿轮410同向以及逆向进行旋转，内齿轮420与太阳齿轮410同向进行旋转。由此，固定于内齿轮420的滚筒轴300与翼轴200同向，并且以比翼轴200还要慢的旋转速度进行旋转，固定于滚筒轴300的滚筒22以比搅拌体24还要慢的旋转速度与搅拌体24同向进行旋转。换言之，搅拌体24以比滚筒22还要快的旋转速度与滚筒22同向进行旋转。
另一方面，在驱动单元30的形态从二轴驱动形态切换到一轴驱动形态的情况下，如图3所示，凸轮652利用转矩电机651进行旋转以使凸轮轴653位于最上方。当凸轮652进行旋转，凸轮轴653向上方移动时，首先，弹簧661收缩。当弹簧661恢复到自然长度时，之后，随着凸轮轴653进行移动，接合棒660会向上方移动，离合器杆630的下端部被接合棒660推动，向上方移动。离合器杆630以支轴641为中心向后方进行旋转，按压部631从离合器体610的凸缘部612分离。离合器体610利用离合器弹簧620的弹力向后方移动，离合器体610的卡合凸缘部613和转子110的被卡合凹部114卡合。
当卡合凸缘部613和被卡合凹部114卡合时，相对于转子110的向离合器体610的圆周方向的转动受限，离合器体610与转子110一同成为能旋转的状态。在这样的状态下，当转子110旋转时，翼轴200以及离合器体610以与转子110的旋转速度相等的旋转速度进行旋转。此时，在行星齿轮机构400中，太阳齿轮410和行星齿轮架440以与转子110相等的旋转速度进行旋转。由此，内齿轮420以与太阳齿轮410以及行星齿轮架440相等的旋转速度进行旋转，固定于内齿轮420的滚筒轴300以与转子110相等的旋转速度进行旋转。即，在驱动单元30中，翼轴200、行星齿轮机构400以及滚筒轴300成为一体进行 旋转。由此，滚筒22和搅拌体24一体旋转。
在洗涤工序以及漂洗工序中，驱动单元30的驱动形态切换成二轴驱动形态。在二轴驱动形态中，当驱动电机100进行动作时，滚筒22以作用于洗涤物的离心力比重力小的旋转速度，搅拌体24以比滚筒22的旋转速度快的旋转速度，左右交互进行旋转。滚筒22内的洗涤物通过由提升筋23举起落下，敲打在滚筒22的内圆周面上。除此之外，在滚筒22的后部，洗涤物与旋转的搅拌体24接触，洗涤物或被揉搓或被搅拌。由此，洗涤物被洗涤或漂洗。
这样，由于在洗涤以及漂洗时，不止是由滚筒22的旋转产生的机械力，由搅拌体24产生的机械力也施加给洗涤物，因此能够期待清洗性能的提高。
在中间脱水工序以及最终脱水工序中，驱动单元30的驱动形态切换成一轴驱动形态。在一轴驱动形态中，当驱动电机100进行工作时，滚筒22以及搅拌体24以作用于洗涤物的离心力远大于重力的旋转速度一体旋转。由于离心力的作用，洗涤物被压到滚筒22的内圆周面上进行脱水。
这样，在脱水时，由于滚筒22和搅拌体24一体地进行旋转，因而紧贴在滚筒22上的洗涤物不需要通过搅拌体24搅拌，就能将洗涤物良好地脱水。
而且，在滚筒22内收容了大量的干燥洗涤物的情况下，洗涤物被压缩在滚筒22的前表面的门体12和滚筒22的后表面的搅拌体24之间，搅拌体24由于洗涤物而成为被压迫的状态。此外，与处于浸湿的状态相比，在洗涤物、搅拌体24处于干燥的状态时，摩擦系数变大。因此，这样地当搅拌体24由于干燥的洗涤物而处于压迫的状态下，当滚筒22和搅拌体24各自进行旋转时，由洗涤物产生的大负荷向搅拌体24施加，从而可以锁定驱动电机100。
因此，在本实施方式中，为了减少搅拌体24和与搅拌体24相接触的洗涤物之间所产生的摩擦力，在搅拌体24的表面设置泼水的供水机构部。
<实施例1>
在本实施例中，供水机构部设置于滚筒22的后表面。供水机构部包含在护圈单元25中。
以下，就搅拌体24和包括供水机构部的护圈单元25的结构进行详细地说明。
图7至图10是表示本实施例的搅拌体24以及护圈单元25的结构的图。图7是安装了搅拌体24以及护圈单元25的状态的滚筒22的正面剖视图。图8是 取下搅拌体24，安装了护圈单元25的状态的滚筒22的正面剖视图。图9(a)、(b)以及(c)分别是图8的A-A′剖面图、B-B′剖面图以及C-C′剖面图。图10以及图11分别是护圈单元25的后视图以及背面立体图。
在搅拌体24的表面，形成从中央部放射状地延伸的多个主叶片24a。此外，搅拌体24的表面，在外周部的两个主叶片24a之间形成辅叶片24b。主叶片24a在与前后方向垂直的面内侧方向上，具有向左旋转方向凸出弯曲的形状。辅叶片24b比主叶片24a小并且低。主叶片24a相当于本发明的突状部。
护圈单元25包括形成为环状并将搅拌体24包围的护圈710和以兼用护圈710的局部的方式与护圈710形成为一体的三个贮水外壳720。护圈单元25被分割成相同形状的三个环形构成构件25a。
在本实施方式中，搅拌体24以能从滚筒22的开口部22a放入的尺寸，设定为尽可能大的尺寸。因此，护圈710的外径设定为比图7以及图8中用点划线的圆表示的滚筒22的开口部22a大。因此，护圈单元25不能在完成的状态下，从口部22a放入到滚筒22内。因此，护圈单元25以分成三个环形构成构件25a的状态从开口部22a放入到滚筒22内，在滚筒22内进行组装。
护圈710包括内周壁711和外周壁712、以及连接内周壁711和外周壁712的上表面壁713，并且下表面开口。在构成贮水外壳720的护圈710的局部上，内周壁711的下部被切开。上表面壁713设定为向外侧凹陷的曲面形状的倾斜面，从而在上表面壁713与洗涤物接触时洗涤物不易损伤。
在滚筒22的后表面的里侧，安装具有向三个方向延伸的臂的大致Y字型的滚筒安装凸缘26，滚筒轴300固定在该滚筒安装凸缘26上。为了缩小向滚筒安装凸缘26的里侧的突出量，滚筒22的后表面的安装了滚筒安装凸缘26的凸缘安装部22c向表面侧膨胀。为了避开该凸缘安装部22c，在与护圈710中的凸缘安装部22c相对应的对应部位710a上，内周壁711以及外周壁712与凸缘安装部22c的膨胀形状相配合地被切开(参照图11)。
在护圈710的内侧，除了凸缘安装部22c和干扰的部分，凸缘部714几乎跨过整周地形成。凸缘部714与搅拌体24的外周部的里面对置。此外，在护圈710上，各环形构成构件25a的两端部的位置上形成螺孔715。螺钉730穿过各螺孔715，通过各环形构成构件25a用螺钉730安装到滚筒22的后表面，从而使护圈单元25以组装好的状态固定在滚筒22的后表面。
护圈710的下表面与滚筒22的后表面相接触。由此，在搅拌体24和滚筒22的后表面之间产生的间隙由于被护圈710埋住，因而能防止洗涤物在因搅拌体24和滚筒22之间摩擦而损伤。
贮水外壳720设置在滚筒22的后表面、与搅拌体24的外周部对置的位置并且远离凸缘安装部22c的位置。贮水外壳720包括：护圈710的局部，比凸缘部714更向内侧突出的上表面板721，从上表面板721的前端部垂下的前表面板722，分隔贮水外壳720和护圈710之间的横分隔板723，将贮水外壳720内分隔为两间的中央分隔板724。
贮水外壳720的下表面是开放的。当护圈单元25安装到滚筒22的后表面时贮水外壳720的下表面在滚筒22的后表面关闭，使得可以在贮水外壳720和滚筒22的后表面形成的空间中存积水。这样，在贮水外壳720和滚筒22的后表面构成贮水部725。贮水部725通过中央分隔板724分为第一贮水部725a和第二贮水部725b。
在前表面板722和第一贮水部725a侧的横分隔板723之间形成间隙，该间隙成为用于获取流向第一贮水部725a的外槽20内的水的第一摄入口726a。此外，在前表面板722和第二贮水部725b侧的横分隔板723之间形成间隙，该间隙成为用于获取流向第二贮水部725b的外槽20内的水的第二摄入口726b。第一摄入口726a在滚筒22进行右旋转时的行进方向侧开口，第二摄入口726b在滚筒22进行左旋转时的行进方向侧开口。由此，在滚筒22进行了右旋转时在第一贮水部725a内水变得容易获取，在滚筒22进行了左旋转时在第二贮水部725b内水变得容易获取。第一摄入口726a以及第二摄入口726b相当于本发明的摄入口。
如上所述，贮水外壳720设置于远离滚筒22的后表面的凸缘安装部22c的区域，即相对于凸缘安装部22c向后方凹陷的区域。由此，由于能升高贮水部725的高度，因而能扩大贮水部725的内部容积，能增多贮水量。
在与上表面板721一起构成贮水外壳720的上表面的护圈710的上表面壁713上，以中央分隔板724为分界，在第一贮水部725a侧和第二贮水部725b侧，分别形成多个用于从第一贮水部725a使水流出的第一流出口727a和用于从第二贮水部725b使水流出的第二流出口727b。第一流出口727a以及第二流出口727b相当于本发明的流出口。
第一贮水部725a以及第二贮水部725b、第一摄入口726a以及第二摄入口726b、第一流出口727a以及第二流出口727b构成包含在护圈单元25中的供水机构部。
在本实施方式的滚筒洗衣机1中，在清洗工序中，在通过二轴驱动形态使滚筒22和搅拌体24分别旋转之前，在外槽20内存积水的状态下通过一轴驱动形态使滚筒22和搅拌体24缓慢地一体地进行旋转，从而进行用由贮水部725提供的水将搅拌体24的表面浸湿的浸湿工序。在浸湿工序中，滚筒22和搅拌体24左右交互地进行旋转。
图12是示意性地表示在浸湿工序下洗涤物被浸湿的样子的图。在图12中，示出了滚筒22进行右旋转的情况的样子，滚筒22进行左旋转的样子与右旋转的情况相同。在图12中，为了方便，搅拌体24通过点划线以透明的状态描述。
滚筒22进行右旋转的情况，主要是发挥第一贮水部725a向搅拌体24的表面泼水的功能。即，如图11所示，当将第一贮水部725a浸到外槽20内存积的水时，水从第一摄入口726a流入到第一贮水部725a内，从而存积到第一贮水部725a内。当第一贮水部725a从水中出来被抬到上方时，第一贮水部725a内存积的水从第一流出口727a流出，泼到搅拌体24的表面。
同样地，滚筒22进行左旋转的情况，主要是发挥第二贮水部725b向搅拌体24的表面泼水的功能。即，当将第二贮水部725b浸到外槽20内存积的水时，水通过第二摄入口726b存积到第二贮水部725b内。然后，第二贮水部725b中存积的水在上方位置从第二流出口727b流出，泼到搅拌体24的表面。
这样，搅拌体24、以及与搅拌体24相接触的洗涤物被浸湿，减少了两者之间产生的摩擦力。
此外，在滚筒22进行右旋转的情况，在第二贮水部725b中，由于第二摄入口726b朝向与滚筒22的旋转方向相反的一侧，因而水不易存积。此外，第二贮水部725b中存积的水在第二贮水部725b被向上方抬起时从第二摄入口726b流出。因此，第二贮水部725b实际上并不发挥向搅拌体24的表面泼水的功能。同样地，在滚筒22进行左旋转的情况，第一贮水部725a实际上并不发挥向搅拌体24的表面泼水的功能。
浸湿工序之外，例如，清洗、漂洗时的滚筒22进行旋转时通过供水机构部向搅拌体24的显示面泼水。这样，滚筒22在外槽20内存积了水的状态下进行 旋转时，能保持搅拌体24和洗涤物之间的摩擦力较低。
在上述的例子中，采用了贮水外壳720的下表面开放的结构，但是也可以采用贮水外壳720的下表面通过下表面板关闭的结构。在这种情况下，贮水部725仅由贮水外壳720构成。
进而，在上述的例子中，配置于滚筒22的后表面的贮水部725、即供水机构部，与护圈单元25形成为一体，但是也可以与护圈单元25独立地形成。
进而，在上述的例子中，虽然在贮水部725和滚筒22的后表面的凸缘安装部22c之间存在间隙，但是只要不与凸缘安装部22c相接触贮水部725可以增大。
<实施例1的效果>
根据本实施例，通过向搅拌体24的表面泼水，浸湿搅拌体24、以及与搅拌体24相接触的洗涤物，能减少双方的两者之间产生的摩擦力。由此，能减少由于与洗涤物的接触而施加给搅拌体24的负荷，能防止驱动电机100的锁定。此外，能防止由于洗涤物与搅拌体24激烈摩擦而导致的布损伤。
此外，根据本实施例，能将外槽20内存积的水通过贮水部725汲上来并泼到搅拌体24的表面，能利用外槽20内的水浸湿搅拌体24的表面等。
进而，在本实施例中，由于通过将贮水部725设置于滚筒22的后表面，能利用滚筒22的旋转将外槽20内的水汲上来，因而能容易地利用外槽20内的水。
进而，在本实施例中，贮水部725被分为第一贮水部725a和第二贮水部725b。然后，在第一贮水部725a内获取水的第一摄入口726a以在滚筒22进行右旋转时向行进方向一侧开口的方式设置，在第二贮水部725b内获取水的第二摄入口726b以在滚筒22进行左旋转时向行进方向一侧开口的方式设置。因此，在滚筒22进行右旋转时，水容易流入到第一贮水部725a中，能在第一贮水部725a中充分地存积水，在滚筒22进行左旋转时，水容易流入到第二贮水部725b中，能在第二贮水部725b中充分地存积水。由此，伴随着滚筒22的左右旋转通过第一贮水部725a和第二贮水部725b高效地将水汲上来，能浸湿搅拌体24。
<实施例1的变更例1>
图13(a)以及(b)是表示本变更例的护圈单元25的结构的图。图13(a)是构成护圈单元25的环形构成构件25a的主视图，图13(b)是环形构成构件25a的后视图。
在上述实施例1中，贮水部725利用贮水外壳720的中央分隔板724分为 第一贮水部725a和第二贮水部725b。与此相对的，在本变更例中，没有设置中央分隔板724，不将贮水部725分为两部分。因此，在贮水部725内获取水的摄入口726在贮水外壳720中，以滚筒22进行右旋转时向成为前侧的端部，进行右旋转时向行进方向一侧开口的方式形成，在成为后侧的端部，前表面板722和横分隔板723相连，不形成摄入口726。在护圈710的上表面壁713上，多个流出口727形成为靠近后侧的端部。
本变更例的贮水部725在滚筒22右旋转时发挥对搅拌体24的表面泼水的功能。
图14是示意性地表示存积于贮水部725的水流出的样子的图。
在本变更例中，在浸湿工序中，滚筒22仅进行右旋转。如图14所示那样，当伴随滚筒22的旋转，贮水部725向上方移动时，在浸泡于外槽20内的水中时存积于贮水部725的水，从流出口727流出。流出的水浸湿搅拌体24以及与搅拌体24接触的洗涤物。
此外，为了不使洗涤物缠绕，也可以有时使滚筒22左旋转。
根据本变更例的构成，由于能增多贮水部725每次的水的上汲量，所以能增多滚筒22的每次旋转泼给搅拌体24的水量。
此外，也可以是摄入口726在贮水外壳720，在滚筒22左旋转时成为前侧的端部，以向左旋转时的行进方向侧开口的方式形成。在这种情况下，在浸湿工序中，滚筒22仅进行左旋转。
<实施例1的变更例2>
图15(a)以及(b)是表示本变更例的护圈单元25的构成的图。图15(a)是构成护圈单元25的环形构成构件25a的主视图，图15(b)是环形构成构件25a的后视图。
在本变更例中，在贮水外壳720，在第一贮水部725a内以沿着各第一流出口727a的方式形成有第一引导筋728a。各第一引导筋728a从护圈710的外周部朝滚筒22右旋转时的行进方向倾斜地延伸。此外，在贮水外壳720，在第二贮水部725b内，以沿着各第二流出口727b的方式形成有第二引导筋728b。各第二引导筋728b从护圈710的外周部朝滚筒22左旋转时的行进方向倾斜地延伸。位于贮水外壳720的最中央侧的第一引导筋728a以及第二引导筋728b取代中央分隔板724将第一贮水部725a和第二贮水部725b分隔开。第一引导筋 728a以及第二引导筋728b相当于本发明的引导筋。
不设置前表面板722于贮水外壳720，贮水外壳720的第一贮水部725a侧的内圆周面整体构成第一摄入口726a，贮水外壳720的第二贮水部725b侧的内圆周面整体构成第二摄入口726b。
图16是示意性地表示存积在第一贮水部725a中的水流出的样子的图。虽然图16是表示滚筒22右旋转时的样子的图，但滚筒22左旋转时也是相同的样子。
在本变更例中，在浸湿工序中，滚筒22左右交替旋转。如图16所示，当第一贮水部725a伴随着滚筒22的右旋转移动到上方时，第一贮水部725a在浸泡于外槽20内的水中时所存积的水从第一流出口727a流出。此时，第一贮水部725a内的水沿着第一引导筋728a流动，顺利地流到第一流出口727a。从第一流出口727a流出的水浸湿搅拌体24以及与搅拌体24接触的洗涤物。
同样，当第二贮水部725b伴随着滚筒22的左旋转移动到上方时，第二贮水部725b在浸泡于外槽20内的水中时所存积的水从第二流出口727b流出。此时，第二贮水部725b内的水沿着第二引导筋728b流动，顺利地流到第二流出口727b。从第二流出口727b流出的水浸湿搅拌体24以及与搅拌体24接触的洗涤物。
通过本变更例的结构，由于能够通过第一引导筋728a将第一贮水部725a内的水顺利地导向第一流出口727a，因此能够良好地使水从第一流出口727a朝向搅拌体24流出。同样，由于能够通过第二引导筋728b将第二贮水部725b内的水顺利地导向第二流出727b，因此能够良好地使水从第二流出口727b朝向搅拌体24流出。
<实施例2>
在本实施例中，给水机构部设置于搅拌体24。
图17以及图18是表示本变更例的搅拌体24的结构的图。图17是搅拌体24的主视图，图18是搅拌体24的后视立体图。
搅拌体24由聚丙烯等树脂材料形成。在搅拌体24的表面形成有多个主叶片801以及多个辅助叶片802。主叶片801以及辅助叶片802的表面的形状分别与实施例1的主叶片24a以及辅助叶片24b相同。
如图18所示，在搅拌体24的背面侧，为了使主叶片801的壁厚变得均匀， 与主叶片801表面突出相对应，在主叶片801的背面形成有凹陷部803。
对于凹陷部803的在搅拌体24右旋转时成为行进方向的后侧的壁面803a具有相对于该行进方向凹曲的形状。在壁面803a形成有通到搅拌体24的表面的多个通水孔804。通水孔804相当于本发明的流出口。在搅拌体24的背面沿着壁面803a的边缘部803b形成有掬水筋805。
在搅拌体24的背面的中心部形成有固定翼轴200的固定毂806。此外，在搅拌体24的背面，主要为了主提高搅拌体24的强度，形成有多个与固定毂806同心的环状的第一加强筋807，和多个往搅拌体24的径向呈放射状延伸的第二加强筋808。
给水机构部由形成于搅拌体24的背面的凹陷部803、通水孔804以及掬水筋805构成。
图19是示意性地表示洗涤物在浸湿工序中被浸湿的样子的图。
在本实施例的浸湿工序中，滚筒22以及搅拌体24右旋转。如图19所示，伴随着搅拌体24的旋转，主叶片801即凹陷部803的前端侧的一部分浸泡于外槽20内的水中。当凹陷部803浸泡在存积于外槽20内的水中时，外槽20内的水通过掬水筋805被掬取，并存积于凹陷部803内。此时，掬水筋805由于具有凹曲形状，因此像铲斗那样发挥功能，外槽20内的水容易通过掬水筋805被掬取，凹陷部803内容易存积水。当凹陷部803从水中出来被举到上方时，存积在凹陷部803内的水从通水孔804流出，泼到搅拌体24的表面。
这样，搅拌体24以及与搅拌体24接触的洗涤物被浸湿，可减少在两者之间产生的摩擦力。
此外，为了不使洗涤物缠绕，也可以使滚筒22以及搅拌体24偶尔进行左旋转。
此外，在本实施例中，也可以在护圈单元25设置与实施例1相同的给水机构部。
<实施例2的效果>
根据本实施例，与实施例1同样，能够减少搅拌体24和与搅拌体24接触的洗涤物之间所产生的摩擦力，并能防止驱动电机100的闭锁以及洗涤物的布损伤。
此外，根据本实施例，能够通过凹陷部803将存积于外槽20内的水上汲并 泼到搅拌体24的表面，能够利用外槽20内的水浸湿搅拌体24的表面。
此外，根据本实施例，将为了使主叶片24a的壁厚变得均匀而必然形成于搅拌体24的背面的凹陷部803用作贮水部，因此能简单方便地实现给水机构部。
此外，根据本实施例，由于能利用搅拌体24的旋转上汲外槽20内的水，因此能容易地利用外槽20内的水。
<实施例2的变更例>
图20是表示本变更例的搅拌体24的结构的搅拌体24的背面立体图。
在本变更例中，凹陷部803不具备掬水筋805。取而代之，在本变更例中，凹陷部803由贮水盖809覆盖，由此，在搅拌体24的背面由凹陷部803和贮水盖809形成有贮水部810。贮水部810的上表面开口。贮水盖809具有形成有多个安装凸耳811的凸缘部812。安装凸耳811通过未图示的螺钉而固定，贮水盖809固定于搅拌体24的背面。
图21是示意性地表示洗涤物在浸湿工序中被浸湿的样子的图。
如图21所示，贮水部810的前端侧的局部伴随着搅拌体24的旋转浸泡在外槽20内的水中。存积于外槽20内的水通过该局部被掬取并存积于贮水部810内。当贮水部810离开水中被举起到上方时，存积于贮水部810内的水从通水孔804流出并泼到搅拌体24的表面。
这样，搅拌体24，以及与搅拌体24接触的洗涤物被浸湿，减少在两者之间产生的摩擦力。
根据本变更例，能够通过贮水部810一次掬取更多的水并存积，能够一次将更多的水泼到搅拌体24的表面。
<实施例3>
在本实施例中，在滚筒22的内圆周面设置有作为给水机构部发挥功能的提升筋900。
图22(a)以及(b)是表示本实施例的提升筋900的结构的图。图22(a)是提升筋900的俯视图，图22(b)是图22(a)的D-D′剖视图。图23(a)以及(b)分别是表示外槽20内的水存积于提升筋900的样子，以及来自提升筋900的水流出而搅拌体24被浸湿的样子的图。
提升筋900具有下表面打开的纵长的中空箱形。提升筋900的前表面901稍稍向后方倾斜，提升筋900的上表面902以越向后方越变高的方式倾斜，提 升筋900的后表面903稍稍向前方倾斜。此外，提升筋900的左侧面904稍稍向右方倾斜，提升筋900的右侧面905稍稍向左方倾斜。此外，当从上方俯视时，提升筋900的上表面902、左侧面904以及右侧面905较小且弯曲为S字形。
在提升筋900处，在由上表面902和后表面903形成的角部形成有多个的通水孔906。通水孔906相当于本发明的流出口。
在滚筒22的内圆周面，大致均等的间隔配置有三个提升筋900。在图23(a)以及(b)的三个提升筋900中，只图示了一个提升筋900，对于剩余的提升筋900，省略图示。如图23(a)以及(b)所示，当在滚筒22的内圆周面安装有提升筋900时，提升筋900的下表面由滚筒22的内圆周面关闭。通水孔906在提升筋900，设于使从通水孔906流出的水泼到搅拌体24的表面的位置，优选设于在滚筒22的前后方向与搅拌体24重叠的位置。
在本实施例的浸湿工序中，滚筒22左右交替旋转。如图22(a)所示，伴随着滚筒22的旋转当提升筋900移动到下方的位置时，提升筋900浸泡于外槽20内的水。通水孔906作为水的摄入口发挥功能，从通水孔906摄入水并存积于提升筋900内。如图22(b)所示，当提升筋900从水中伸出并上升到上方时，存积于提升筋900内的水从通水孔906流出，泼到搅拌体24的表面。当提升筋900上升到上方并倒立时，上表面902以使后方侧变低的方式倾斜。因此，提升筋900内的水容易流向提升筋900的后部，并容易从通水孔906流出。
这样，由从通水孔906流出的水浸湿搅拌体24以及与搅拌体24接触的洗涤物，可以减少在两者之间所产生的摩擦力。
此外，滚筒22在采用以使后表面侧变低的方式相对于水平轴倾斜的结构的情况下，提升筋900的上表面902也可以不倾斜。在这种情况下，通过滚筒22倾斜，从而提升筋900内的水变得容易流向提升筋900的后部，并容易从通水孔906流出。
此外，在本实施例中，也可以在护圈单元25设有与实施例1相同的给水机构部。进一步地，也可以在搅拌体24设有与实施例2相同的给水机构部。
<实施例3的效果>
根据本实施例，与实施例1同样，能减少搅拌体24和与搅拌体24接触的洗涤物之间所产生的摩擦力，能防止驱动电机100的锁定以及洗涤物的布损伤。
此外，根据本实施例，能够通过提升筋900将存积于外槽20内的水上汲并 泼到搅拌体24的表面，能够利用外槽20内的水浸湿搅拌体24的表面。
此外，根据本实施例，由于能够将用于搅拌洗涤物的提升筋900作为贮水部使用，因此使给水机构部实现简易。
此外，根据本实施例，由于能够利用滚筒22的旋转上汲槽20内的水，因此能够容易地利用外槽20内的水。
<实施例3的变更例>
在上述实施例3中，作为摄入口的通水孔906也可以设置与通水孔906不同的摄入口。
图24(a)以及(b)是分别表示本变更例的提升筋900的结构的图。在本变更例的提升筋900处，在提升筋900的左侧面904以及右侧面905的前部分别设有摄入口907。在该位置设有摄入口907的情况下，摄入口907为了在滚筒22旋转时的行进方向开口，容易从摄入口907摄入水。此外，当提升筋900上升到上方时，难以从摄入口907漏出水。此外，两个摄入口907以在前后方向稍微错开的方式设置，从一方的摄入口907摄入的水难以从另一方的摄入口907漏掉。
<其它的变更例>
以上，虽然就本发明的一个实施方式进行了说明，但各部分的具体的结构不只局限于上述的实施方式，此外，本发明的实施方式也可以在上述之外进行各种变形。
例如，在上述实施方式的实施例3中，作为给水机构部提升筋900发挥功能。然而，如图25(a)以及(b)所示，与提升筋900不同，也可以在滚筒22的内圆周面的后部形成有构成给水机构部的贮水部950。贮水部950例如由中空的箱体结构组成，在与搅拌体24对置的面设有构成摄入口以及流出口的通水孔951。虽然在图25(a)以及(b)图示一个贮水部950但贮水部950优选以大致均等的间隔设有两个以上。
如图25(a)所示，当伴随滚筒22的旋转，贮水部950移动到下方的位置时，贮水部950浸泡于外槽20内的水中。从通水孔951摄入水，并存积于贮水部950内。如图25(b)，当贮水部950从水中出来而上升到上方时，存积于贮水部950内的水从通水孔951流出，并泼到搅拌体24的表面。搅拌体24以及与搅拌体24接触的洗涤物被浸湿，减少了两者之间产生的摩擦力。
进而，在上述实施方式中，优选如图26(a)所示，以搅拌体24的表面的位置P1与护圈710的前表面的位置P2相比更处于前方的方式，将搅拌体24以及护圈单元25安装于滚筒22的后表面。如图26(b)的比较例所示，在护圈710的前表面的位置P2与搅拌体24的表面的位置P1相比更处于前方的情况下，由搅拌体24搅拌的洗涤物会接触护圈710的内圆周面，并被该内圆周面引导，从而变得容易夹入到搅拌体24与护圈710之间。即，变得容易在搅拌体24与护圈710之间咬入洗涤物，有可能会损伤洗涤物。在这点上，在做成搅拌体24的表面的位置P1与护圈710的前表面的位置P2相比更处于前方的结构的情况下，洗涤物不会接触护圈710的内圆周面，在搅拌体24与护圈710之间难以咬入洗涤物。
进而，在上述实施方式中，滚筒22以水平轴为中心进行旋转。然而，滚筒洗衣机1也可以做成滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转这样的结构。在这种情况下，例如外槽20以及滚筒22的倾斜角度可做成10～20度左右。
进而，虽然上述实施方式的滚筒洗衣机1不具备烘干功能，但本发明也能应用于具备烘干功能的滚筒洗衣机即滚筒洗涤烘干机。
另外，本发明的实施方式能够在权利要求书所示出的技术思想的范围内适当地进行各种变更。
