以下，参照附图，对本发明的实施方式进行具体说明。图1是本发明的一实施方式的洗衣机1的纵剖面图。首先，以图1的上下方向Z为基准，对洗衣机1的概要进行说明。纵向即上下方向Z之中，将上侧称为上侧Z1，将下侧称为下侧Z2。需要说明的是，洗衣机1不仅包括进行洗涤物的洗涤运转、漂洗运转以及脱水运转的洗衣机，也包括还进行烘干运转的洗干一体机。洗衣机1包括：形成为箱状的壳体2、配置于壳体2内的外桶3、洗涤桶4、马达5、抽水路6以及搅拌构件7。
外桶3例如为树脂制，并形成为在其下端设有底壁3A的有底圆筒状。在外桶3的上端形成有开口部3B。在外桶3内，自来水、洗澡水以及溶解有洗涤剂的液体等水从底壁3A侧蓄积。
洗涤桶4形成为比外桶3小一圈的有底圆筒状。洗涤桶4具有：大致圆筒状的圆周壁4B，上端具有出入口4A；以及圆盘状的底壁4C，从下侧Z2堵住圆周壁4B的中空部分。例如，圆周壁4B为金属制，底壁4C中，圆心部为金属制，外周部为树脂制。底壁4C的外缘部形成为向上侧Z1弯折的筒状，可以视作圆周壁4B的下端部。底壁4C和圆周壁4B的与底壁4C连接的下端部构成洗涤桶4的底部4D。在洗涤桶4中，将被圆周壁4B包围并被底壁4C从下侧Z2堵住且从出入口4A向上侧Z1敞开的大致圆筒状的内部空间称为主收容空间4E。洗涤桶4同轴状地收容于外桶3内，并由外桶3的底壁3A支承。该状态的洗涤桶4能绕穿过洗涤桶4的圆心并沿上下方向Z延伸的轴线J旋转。这样的洗衣机1是纵向配置洗涤桶4的立式洗衣机。
洗涤桶4的轴线J也是外桶3的中心，洗涤桶4的旋转方向与绕轴线J的周向P一致。以下，将以轴线J为中心的径向称为径向R，在径向R之中，将轴线J侧也就是朝向轴线J的一侧称为径向内侧R1，将背向轴线J的一侧称为径向外侧R2。周向P和径向R都是沿着水平方向H的方向。
洗涤桶4的出入口4A呈与外桶3的开口部3B连通的状态。开口部3B以 及出入口4A例如通过设置于壳体2的门8一起开闭。洗衣机1的使用者能经由敞开的出入口4A向洗涤桶4内投取洗涤物。在圆周壁4B以及底壁4C分别形成有贯通孔4F，外桶3内的水经由贯通孔4F在外桶3与洗涤桶4之间往来。由此，洗涤桶4从底壁4C侧蓄水至与外桶3水位相同。蓄于外桶3以及洗涤桶4的水经由与外桶3的底壁3A连接的排水路9排出机外。

中构件17形成为具有与轴线J一致的中心轴线的大致圆筒状。在中构件17的外周面17A，下端部呈外径遍及上下方向Z的整个区域大致固定的圆筒面，但该下端部的上侧的部分是随着朝向上侧Z1而平滑地缩径的球面。在外周面17A的下端部一体地设有向径向外侧R2突出的多个突出部17B。在本实施方式中，由相邻的两个突出部17B构成的组沿周向P等间隔排列地配置。在突出部17B的组与相邻于该组的另一组之间，形成有沿周向P延伸并向上侧Z1稍微切开中构件17的下端缘的缺口17C。缺口17C存在多个，沿周向P等间隔地配置。由此，中构件17的下端缘一边交替凹凸一边沿周向P延伸。在各突出部17B中，上表面沿水平方向H呈平坦状，径向外侧R2的侧面以随着朝向下侧Z2而偏向径向内侧R1的方式弯曲，在该侧面形成有向径向内侧R1凹陷的凹槽。由此， 从径向外侧R2观察，该侧面形成为上下朝向颠倒的大致U字状。
中构件17的与外周面17A的上端连接的上端面17D为圆环状，沿水平方向H延伸。在中构件17的上端形成有被上端面17D包围的圆形的上开口17E。在中构件17的内周面17F中，大致下半部为随着朝向上侧Z1而缩径的锥形面，大致上半部为随着朝向上侧Z1而比该大致下半部更缩径的锥形面(也参照后述的图4)。在中构件17的下端形成有被内周面17F的下端缘包围的圆形的下开口17G。
中构件17载置于下构件15的底面部15G。在该状态下，中构件17的各突出部17B中的径向外侧R2的侧面沿着底面部15G的外侧倾斜面部15K的外周部的弯曲而从上侧Z1与该外周部接触。外侧倾斜面部15K中的各凹部15N配置于由相邻的两个突出部17B构成的任一组中的这两个突出部17B之间。中构件17的下端缘的各缺口17C配置在与位于相邻的凹部15N之间的两个排水孔15P在周向P上对齐的位置。中构件17的下端缘中相邻的缺口17C之间的部分从上侧Z1与外侧倾斜面部15K中比排水孔15P更偏向径向内侧R1的中途部接触。因此，中构件17的内周面17F从外侧倾斜面部15K的该中途部立起而一边向径向内侧R1弯曲一边延伸(参照图4)。此外，中构件17的下开口17G虽然被下构件15从下侧Z2堵住，但是从各缺口17C向径向外侧R2敞开。
上构件18形成为具有与轴线J一致的中心轴线的大致圆筒状。在上构件18的外周面，以沿周向P等间隔地排列的方式设置有多个凸部18A，在相邻的凸部18A之间逐一设置有凹部18B。各凸部18A形成为将上构件18的下端部与上端部连接并向径向外侧R2凸起的筋条状。在各凸部18A中的靠上区域形成有多个贯通孔18C。各凹部18B形成为将上构件18的下端部与上端部连接并向径向内侧R1凹陷的槽状。在上构件18的上端部形成有：圆形的出入口18D；以及圆环状的槽18E，从径向外侧R2包围出入口18D并沿周向P延伸。在上构件18的上端部设有圆环状的肋18F，配置于出入口18D与槽18E之间并将它们包边，并且沿上下方向Z延伸。
在上构件18的内周面中，在周向P上与各凸部18A一致的部分形成为向径向外侧R2凹陷的凹状，在周向P上与各凹部18B一致的部分形成为向径向内侧R1突出的凸状。在上构件18的下端面中与各凹部18B一致的部分设有伸出部 18G，周向P上的尺寸长且沿水平方向H向径向内侧R1伸出。伸出部18G存在多个，沿周向P等间隔地排列。在各伸出部18G设有向下侧Z2突出的凸起18H。在凸起18H形成有从其下端面向上侧Z1延伸的螺孔18I。在上构件18的下端面形成有开口18J，被这些伸出部18G包围并将上构件18的内部空间向下侧Z2敞开。
上构件18从上侧Z1覆盖载置于下构件15的底面部15G的中构件17。在该状态下，上构件18的设有出入口18D的上端部从上侧Z1与中构件17的将上开口17E包围的上端面17D接触，出入口18D从上侧Z1与上开口17E连通(参照图4)。此外，上构件18的各伸出部18G从上侧Z1与中构件17的任一组两个突出部17B的上表面接触，各伸出部18G的凸起18H穿过这两个突出部17B之间，嵌入下构件15的底面部15G处的任一凹部15N中。下构件15的从各凹部15N露出的插通孔15F从下侧Z2与凸起18H的下端面的螺孔18I连通。
螺栓19从下侧Z2逐一插通从下构件15的下表面部处的各凸起15E的下端面露出的插通孔15F，组装于螺孔18I。由此，上构件18以在其与下构件15之间夹着中构件17的状态固定于下构件15，搅拌构件7的主体13得以完成。需要说明的是，也可以代替使用螺栓19，通过粘接、焊接等来使上构件18固定于下构件15。此外，通过使上构件18的各凸起18H位于中构件17的各组的两个突出部17B之间，中构件17以在周向P上被定位的状态固定于下构件15以及上构件18。在主体13中，下构件15的圆环状的外缘部15H向径向外侧R2呈凸缘状伸出配置。
盖14包括盖主体25、盖罩26、以及衬垫27。盖主体25形成为具有与轴线J一致的中心轴线的圆盘状。在盖主体25的上表面部的中央部设有：圆环状的槽25A，沿周向P延伸；以及大致圆柱状的把持部25B，被槽25A包围。沿径向R横切槽25A的多个分隔部25C以沿周向P等间隔地排列的方式设置于槽25A。在盖主体25形成有沿上下方向Z贯通盖主体25的多个贯通孔25D。盖主体25的外缘部具有：内侧圆筒部25E，向下侧Z2弯曲；以及外侧圆筒部25F，包围内侧圆筒部25E的上端部。由此，在盖主体25的外缘部形成有圆环状的槽25G，在内侧圆筒部25E与外侧圆筒部25F之间向上侧Z1凹陷，同时沿周向P延伸(也参照图4)。在内侧圆筒部25E中比上端部偏向下侧的外周面，形成有 L字状的卡定槽25H，从该外周面的下端缘向上侧Z1延伸之后弯折成大致直角并沿周向P延伸。卡定槽25H设置为单个或多个，在本实施方式中，沿周向P等间隔排列地设置有多个卡定槽25H。
盖罩26形成为圆盘状。盖罩26的下表面部26A可以向上侧Z1凸弯曲。在盖罩26的外缘部设有向上侧Z1突出的爪状的卡合部26B。卡合部26B设置为单个或多个，在本实施方式中，等间隔排列地设置有多个卡合部26B。盖罩26与盖主体25同轴状地配置。各卡合部26B与设置于盖主体25的内侧圆筒部25E的内周面的卡合孔25I(参照图3)一一卡合。由此，盖罩26与盖主体25被设为一体。
衬垫27能使用例如O型环。衬垫27嵌入盖主体25的外缘部的槽25G，以配置于槽25G的底部的状态与盖主体25一体化(也参照图4)。
使用者单手抓住盖14的把持部25B，使其朝向主体13的上构件18的出入口18D下降。这样，盖主体25的外侧圆筒部25F从上侧Z1进入上构件18的出入口18D的周围的槽18E，相反地，上构件18的出入口18D与槽18E之间的肋18F从下侧Z2进入盖主体25的外缘部处的槽25G。此时，上构件18的设置于槽18E内的突起18K(参照图2)从下侧Z2进入盖主体25的卡定槽25H。然后，当抓住把持部25B的使用者绕轴线J转动盖14时，由于突起18K进入卡定槽25H的沿周向P延伸的水平部分而无法向上下方向Z移动，因此盖14以堵住出入口18D的状态装接于上构件18。由此，搅拌构件7得以完成。需要说明的是，由于肋18F处于与槽25G内的衬垫27接触的状态，因此盖14能以不会随意反向转动的方式慢慢停止。当使用者单手抓住把持部25B并反向转动盖14使其向上侧Z1移动时，突起18K离开卡定槽25H，因此能使盖14从主体13脱离。
参照完成后的搅拌构件7的纵剖面图即图4，在搅拌构件7的内部设有副收容空间7A。副收容空间7A是独立于洗涤桶4内的主收容空间4E的空间。在搅拌构件7设有内表面部7B，由下构件15的底面部15G、帽部16的上表面部、中构件17的内周面17F、盖14的盖罩26的下表面部26A构成。内表面部7B的将副收容空间7A包围的部分形成为向上侧Z1凸弯曲的圆顶状。由此，副收容空间7A本身也形成为向上侧Z1凸弯曲的圆顶状。底面部15G和帽部16的上表面部从下侧Z2堵住副收容空间7A，内周面17F从径向外侧R2并且从上侧 Z1堵住副收容空间7A，下表面部26A以与内周面17F的上侧Z1的内周缘连接的状态，从上侧Z1堵住副收容空间7A。在底面部15G的外侧倾斜面部15K中，设有排水孔15P的径向外侧R2的端部是内表面部7B的距离轴线J最远的端部。在中构件17的外周面17A与上构件18的各凸部18A之间，逐一形成有排水路7C，随着朝向上侧Z1而向径向内侧R1弯曲。各排水路7C处于经由凸部18A的贯通孔18C而与搅拌构件7的外部连通的状态。各排水路7C的下端处于如下状态：经由在中构件17的下端缘处在周向P上位于相同位置的缺口17C，与副收容空间7A连通。
接着，对洗衣机1所进行的洗涤进行说明。以下说明的洗涤是一般的标准模式下的洗涤。参照图1，在洗涤运转开始之前，使用者打开门8，经由出入口4A将洗涤物放入洗涤桶4。在洗涤物包括容易破损或变形的易损洗涤物的情况下，使用者将搅拌构件7的盖14从主体13取下而将出入口18D敞开，将易损洗涤物从出入口18D放入搅拌构件7的副收容空间7A，之后将盖14装配于主体13而关闭出入口18D。此外，使用者将易损洗涤物之外的普通洗涤物从出入口4A放入洗涤桶4的主收容空间4E。需要说明的是，易损洗涤物在一次洗涤的所有洗涤物中所占的比例例如为10％左右。
以装接于主体13的盖14的外侧圆筒部25F能保有游隙地进入主体13的槽18E的方式，设定外侧圆筒部25F的厚度、槽18E的槽宽(参照图4)。该游隙设定为如下程度的大小：能使盖14顺利拆装于主体13，能防止盖14与主体13之间的碰撞声，并且，在洗涤物从出入口18D露出时不能从副收容空间7A装配盖14。此外，如上所述，在副收容空间7A内，由于帽部16从上侧Z1覆盖螺栓21的头部，因此能防止洗涤物与螺栓21接触而受到损伤。
投入了所有洗涤物的使用者将门8关闭。需要说明的是，在投入洗涤物之后，使用者打开抽水路6B的罩12，将洗涤剂从抽水路6B的洗涤剂投入口6C投入流路11内。溶解有该洗涤剂的水作为洗涤水蓄于外桶3以及洗涤桶4中。这时，洗涤水的一部分经由搅拌构件7的下构件15的放水孔15M(参照图4)而从下侧Z2流入搅拌构件7的副收容空间7A。此外，洗涤水的一部分穿过搅拌构件7的下构件15的排水孔15P和中构件17的缺口17C或者穿过上构件18的贯通孔18C、排水路7C以及缺口17C，由此，从径向外侧R2也流入副收容 空间7A(参照图4)。由此，在洗涤桶4内，洗涤水不仅蓄于主收容空间4E，也蓄于副收容空间7A。需要说明的是，由于在洗涤水流入副收容空间7A时，副收容空间7A内的空气通过盖主体25的贯通孔25D(参照图4)而流出，因此能顺利地为主收容空间4E填满洗涤水。这种情况下，用于将副收容空间7A内的空气顺利导入贯通孔25D的通气孔(未图示)可以设置于盖14的盖罩26。
当洗涤水蓄于主收容空间4E以及副收容空间7A中时，在洗涤桶4静止的状态下搅拌构件7进行旋转，主收容空间4E内的搅拌构件7上的普通洗涤物被旋转的搅拌构件7的上构件18的凸部18A搅拌。此外，蓄于洗涤桶4的底部4D的洗涤水被旋转的搅拌构件7的下构件15的叶片15D送入各抽水路6并在流路11内上升，从各抽水路6的出口11A排出并被浇淋到主收容空间4E的洗涤物上。需要说明的是，之前从洗涤剂投入口6C投入流路11内的洗涤剂通过旋转的叶片15D有效地溶于水。通过被搅拌、被洗涤水浇淋或被洗涤水中所含的洗涤剂分解污垢，从而洗涤主收容空间4E的洗涤物。此外，随着搅拌构件7的旋转，在副收容空间7A内产生洗涤水的水流。由此，副收容空间7A内的易损洗涤物通过被该水流搅拌、被洗涤水浇淋或被洗涤水中所含的洗涤剂分解污垢而被洗涤。
在搅拌构件7开始旋转并经过了规定时间之后，搅拌构件7的旋转停止，外桶3以及洗涤桶4内的水被排出。这时，流入副收容空间7A的洗涤水通过搅拌构件7的放水孔15M、排水孔15P(参照图4)向搅拌构件7外流出。当排水完成时，洗涤运转结束。
在洗涤运转后的漂洗运转中，在自来水作为漂洗水而蓄于外桶3、洗涤桶4以及搅拌构件7中后，在洗涤桶4静止的状态下，搅拌构件7进行旋转。由此，主收容空间4E的洗涤物通过在漂洗水中被搅拌构件7搅拌或被来自抽水路6的漂洗水浇淋而被漂洗。此外，搅拌构件7的副收容空间7A内的易损洗涤物通过由搅拌构件7的旋转而在副收容空间7A产生的漂洗水的水流而被漂洗。在搅拌构件7开始旋转并经过规定时间之后，搅拌构件7的旋转停止，当外桶3、洗涤桶4以及搅拌构件7内的水被排出时，漂洗运转结束。
脱水运转在漂洗运转之后作为最终脱水进行实施，但是也可以作为中间脱水而在洗涤运转之后立即实施。脱水运转中，洗涤桶4与搅拌构件7成为一体 而高速地进行脱水旋转。由此，水分从主收容空间4E内的洗涤物渗出，并从洗涤桶4的贯通孔4F排出。这时，参照图4，水分也从搅拌构件7的副收容空间7A内的洗涤物渗出而移向径向外侧R2，并通过中构件17的缺口17C，主要从底面部15G的外侧倾斜面部15K的排水孔15P排出(参照虚线箭头)。副收容空间7A内的水分也可以在通过缺口17C之后，在排水路7C中上升并从上构件18的凸部18A的贯通孔18C排出(参照单点划线箭头)。需要说明的是，在副收容空间7A内未从排水孔15P、贯通孔18C排尽的水分通过形成于底面部15G的最下部的放水孔15M而落下，从而自然地排出。当最终脱水结束时，洗衣机1中的洗涤结束。使用者将门8打开而从洗涤桶4的出入口4A取出主收容空间4E的洗涤物，并取下搅拌构件7的盖14而从出入口18D取出副收容空间7A的洗涤物。
如上所述，由于在洗衣机1中，洗涤桶4的主收容空间4E能收容普通洗涤物，而设置于对主收容空间4E内的洗涤物进行搅拌的搅拌构件7的内部的副收容空间7A能收容易损洗涤物，因此能以一次标准模式将普通洗涤物和易损洗涤物一并进行洗涤。因此，能减少以将洗涤运转等时的马达5的最大转速设定为低于标准模式的干洗模式分开洗涤易损洗涤物的情况所需的时间、电量、水量。因此，洗衣机1能省略干洗模式本身。
由于搅拌构件7的内表面部7B的将副收容空间7A包围的部分为向上侧Z1凸弯曲的圆顶状，没有凹凸而光滑，因此能抑制副收容空间7A内的易损洗涤物与内表面部7B接触而受到损伤。需要说明的是，作为内表面部7B的一部分的中构件17的内周面17F虽然由锥形面构成，但也可以是球面。此外，由于副收容空间7A的直径小于洗涤桶4内的主收容空间4E，因此旋转中的搅拌构件7的振动小。因此，因搅拌构件7的振动而产生的噪音小，能抑制副收容空间7A内的洗涤物因振动而导致过分活动，因此能进一步抑制该洗涤物受到损伤。进而，由于副收容空间7A位于洗涤桶4内的下部，因此即使是容易浮在水中的小件物品等洗涤物，也能在副收容空间7A内使该洗涤物整体浸到水中，因此能以与前述的干洗模式的情况同等程度的完成情况进行洗涤。
在洗涤桶4脱水旋转时，以洗涤桶4的轴线J为中心的离心力作用于副收容空间7A内的水分，由此，这些水分以离开轴线J的方式移动。通过将这些水分 从设置于搅拌构件7的内表面部7B的距轴线J最远的端部的排水孔15P排出，能有效地将副收容空间7A内的易损洗涤物脱水。此外，如上所述，由于副收容空间7A的直径小于主收容空间4E，而且副收容空间7A的容量比较小，因此能减轻洗涤桶4脱水旋转时作用于副收容空间7A内的易损洗涤物的离心力。由此，能与前述的干洗模式的情况同等程度地抑制该洗涤物的损伤。
通过使副收容空间7A中从排水孔15P排出的水从设置于搅拌构件7的从下侧Z2堵住副收容空间7A的底面部15G的内侧倾斜面部15J以及外侧倾斜面部15K的下端的放水孔15M落下，从而能可靠地排出。
本发明不限于以上说明的实施方式，能在技术方案所述的范围内进行各种变更。
例如，搅拌构件7的主体13可以分割为下构件15、帽部16、中构件17以及上构件18，但也可以形成为一体。
此外，洗涤桶4的轴线J虽然在上述实施方式中沿着垂直方向，但也可以相对于垂直方向倾斜。
