Description

清洗机 技术领域
本发明涉及一种清洗机。
背景技术
专利文献1中记载的洗衣机包括：洗衣机外壳、吊挂在洗衣机外壳的内部的接水桶、旋转自如地设置于接水桶内的洗涤兼脱水桶、旋转自如地设置于洗涤兼脱水桶的内底部的波轮、以及设置在洗涤兼脱水桶内的高度方向的中途的洗涤物载置用网。将洗涤物放在洗涤物载置用网上后，向洗涤兼脱水桶投入水和洗涤剂后，开始运转洗衣机，波轮旋转。通过波轮的旋转，波轮上部的清洗水成为从上侧朝向下侧的水流，通过洗涤物的内部。
在专利文献1的洗衣机中，具有较厚形状的波轮体积大，因此洗涤兼脱水桶内变窄。进而，在运转过程中，洗涤物在洗涤兼脱水桶内只能在洗涤物载置用网的上侧的区域自由移动。这样的话，由于在洗涤兼脱水桶内能用于对洗涤物进行清洗的区域狭窄，因此有可能为了清洗而无法充分地搅拌洗涤物。因此，在提高洗涤物的清洗力方面存在极限。

发明内容
发明所要解决的问题
本发明是在该背景下完成的，其目的在于提供一种能够谋求提高清洗力的清洗机。
用于解决问题的方案
本发明是一种清洗机，包括：清洗桶，形成有收纳清洗对象并蓄积水的内部空间，具有从下侧与所述内部空间对置的底板部；水流产生构件，在所述内部空间配置在所述底板部的上侧，通过旋转在所述内部空间产生水流，所述水流产生构件具有：平板状的顶板部，具有与所述底板部的板厚方向一致或者大致一致的板厚方向；以及多个叶片部，设置于所述顶板部的下表面部，排列在绕所述水流产生构件的旋转轴线的周向上，以远离所述旋转轴线的方式延伸；以及水路，夹在所述周向上相邻的所述叶片部之间，随着所述水流产生构件的旋转使水以远离所述旋转轴线的方式流动。
此外，本发明的特征在于，所述多个叶片部包括第一叶片部和第二叶片部，所述第二叶片部在以所述旋转轴线为中心的径向上比所述第一叶片部短，在所述周向上与所述第一叶片部交替地排列。
此外，本发明的特征在于，所述第二叶片部的所述径向的内侧的端缘配置为：相比于所述第一叶片部的所述径向的内侧的端缘，偏向所述径向的外侧。
此外，本发明的特征在于，所述水流产生构件包括：闭塞部，与所述多个叶片部的下端连接，从下侧堵住所述水路。
此外，本发明的特征在于，包括：电机；以及传递轴，用于将所述电机的驱动力传递至所述水流产生构件，在所述闭塞部的位于所述旋转轴线侧的区域形成有引入口，该引入口用于将所述闭塞部的下侧的水引入至所述水路，所述传递轴从下侧插通于所述引入口，在所述顶板部设置有与所述传递轴连结的连结部。
此外，本发明的特征在于，包括：分隔构件，在所述内部空间配置于所述水流产生构件的上侧，将所述内部空间在上下分隔成：配置有所述水流产生构件的配置区域、以及配置有清洗对象的清洗区域，在所述分隔构件形成有使所述配置区域与所述清洗区域连通的连通口，在所述清洗桶的包括所述底板部的底部形成有引导部，该引导部将在所述水路中流向所述径向的外侧的水导向所述连通口。
发明效果
根据本发明，当配置于从下侧与清洗桶的内部空间对置的底板部的上侧的 水流产生构件旋转时，在水流产生构件的顶板部的下表面部夹在相邻的叶片部之间的水路内的水通过离心力，以远离水流产生构件的旋转轴线的方式流动。通过该水势，在清洗桶的内部空间产生水流，该水流泼向内部空间的清洗对象，由此对清洗对象进行清洗。
顶板部是具有与底板部的板厚方向一致或者大致一致的板厚方向的平板状，因此能在底板部的板厚方向上较小地构成整个水流产生构件。由此，在清洗桶的内部空间，能将水流产生构件的配置区域抑制得较小，另一方面，能确保清洗对象的清洗区域较宽，因此，在清洗区域中能使水流充分地泼向清洗对象。因此，能够谋求提高清洗力。
此外，根据本发明，排列在绕水流产生构件的旋转轴线的周向上的多个叶片部包括在周向上交替地排列的第一叶片部和第二叶片部，第二叶片部在以旋转轴线为中心的径向上比第一叶片部短。由此，通过这些第一叶片部之间的第二叶片部能将在周向上夹在相邻的第一叶片部之间的空间分割成即使在远离旋转轴线的位置周向的尺寸也不太变化的两个水路。因此，通过分成两个狭窄的水路，能使从旋转轴线侧流入该空间的水以维持高水压的状态从各水路流出。由此，在清洗桶的内部空间产生流势强的水流，通过该水流能有效地对清洗对象进行清洗，能够谋求进一步提高清洗力。此外，通过将多个叶片部构成为：在径向上的长度不同的第一叶片部和第二叶片部交替地排列，能使叶片部的形状简单化。
此外，根据本发明，第二叶片部的径向的内侧的端缘配置为：相比于第一叶片部的径向的内侧的端缘偏向径向的外侧。由此，在相邻的第一叶片部之间的径向的内侧的端缘间，能确保用于大量地接受将要从旋转轴线侧流入至各水路的水的空间。由此，能使大量的水在各水路中流动，在清洗桶的内部空间高效地产生流势强的水流。因此，能通过该水流有效地对清洗对象进行清洗，能够谋求进一步提高清洗力。
此外，根据本发明，由于水流产生构件的与多个叶片部的下端连接的闭塞部从下侧堵住水路，因此，各水路的上下的尺寸被固定，并且除了在径向上的两端部以外，各水路呈被密封的状态。由此，各水路的水不会在中途从水路流出，而能以维持高水压的状态流至水路的径向外侧的出口。因此，能通过从水 路的出口流出的水，在清洗桶的内部空间高效地产生流势强的水流，通过该水流能有效地对清洗对象进行清洗，因此能够谋求进一步提高清洗力。
此外，根据本发明，用于将电机的驱动力传递至水流产生构件的传递轴不与闭塞部连结，而是与顶板部连结，因此在闭塞部的旋转轴线侧的区域中，能形成大引入口。由此，通过将大量的水从引入口引入各水路，能在清洗桶的内部空间高效地产生流势强的水流。因此，通过该水流能有效地对清洗对象进行清洗，能够谋求进一步提高清洗力。
此外，根据本发明，清洗桶的内部空间处于被分隔成在分隔构件的下侧配置有水流产生构件的配置区域、以及在分隔构件的上侧配置有清洗对象的清洗区域的状态，因此能防止清洗对象与旋转中的水流产生构件接触而损伤清洗对象。由此，能提高水流产生构件的转速，因此能够谋求提高清洗力。
配置区域和清洗区域经由形成于分隔构件的连通口处于连通的状态，形成于清洗桶的底部的引导部将在水路中流向径向的外侧的水导向连通口。由此，能缩短从水路到连通口的路径。因此，在水路中流动的水以维持高水压的状态能迅速到达清洗区域，因此在清洗区域中能高效地产生强水流，通过该水流能有效地对清洗对象进行清洗。由此，能够谋求进一步提高清洗力。引导部不是单独的零件，而是形成于清洗桶的底部，因此能够谋求削减零件件数。

具体实施方式
以下，参照附图，对本发明的实施方式的清洗机1进行具体的说明。清洗机1是用于对清洗对象Q进行清洗的装置。作为清洗对象Q的一例是衣物等洗涤物，在该情况下，清洗机1是洗衣机。作为清洗对象Q的其他例子是水果和蔬菜等。清洗机1也可以具有烘干清洗对象Q的功能。
图1是清洗机1的内部构造的纵剖面图。首先，以图1中的上下方向Z为基准对清洗机1的概要进行说明。在纵向即上下方向Z中，将上侧称为上侧Z1，将下侧称为下侧Z2。清洗机1包括：形成为箱状的壳体2、配置于壳体2内的外桶3、能够在外桶3内旋转的清洗桶4、配置于清洗桶4内的分隔构件5以及抽水构件6、使清洗桶4旋转的电机7、以及通过接受电机7的驱动力在清洗桶4内能够旋转的水流产生构件8。需要说明的是，在该清洗机1中没有配备一般的洗衣机中所使用的波轮。
外桶3例如为树脂制，形成为具有在上下方向Z延伸的中心轴线的有底圆筒状。外桶3具有：在上端具有开口部3A的大致圆筒状的圆周壁3B、以及从下侧Z2堵住圆周壁3B的中空部分的圆板形状的底壁3C。开口部3A通过与圆周壁3B的上端部连结的罩(未图示)进行开闭。在外桶3内从底壁3C侧蓄积有自来水、洗澡水以及溶解有洗涤剂的液体等的水。
清洗桶4具有在上下方向Z延伸的中心轴线，形成为比外桶3小一圈的有底圆筒状。就是说，清洗桶4处于纵向配置的状态。在清洗桶4形成有收纳清洗对象Q的大致圆柱状的内部空间10。清洗桶4具有：在上端具有出入口4A并包围内部空间10的大致圆筒状的圆周壁4B、以及从下侧Z2与内部空间10对置的圆板形状的底板部4C。底板部4C的板厚方向与上下方向Z一致或者大致一致。例如，圆周壁4B为金属制，在底板部4C中，圆心部分为金属制，外周部分为树脂制。底板部4C与圆周壁4B的与底板部4C连接的下端部构成清洗桶4的底部4D。清洗桶4以同轴状收纳于外桶3内。清洗桶4能够以通过此圆心的中心轴线为中心进行旋转。将清洗桶4的中心轴线称为旋转轴线J。
以下，将绕旋转轴线J的周向称为周向S，将以旋转轴线J为中心的径向称为径向R。周向S以及径向R均是沿着水平方向H的方向。在径向R中，将靠 近旋转轴线J的一侧称为径向内侧R1，将远离旋转轴线J的一侧称为径向外侧R2。
出入口4A在使内部空间10向上侧Z1露出的状态下从下侧Z2与开口部3A连通，开口部3A以及出入口4A通过前述的罩(未图示)一起开闭。清洗机1的使用者经由开放的出入口4A，能将清洗对象Q从清洗桶4的内部空间10取出、或者将清洗对象Q放入清洗桶4的内部空间10。在圆周壁4B以及底板部4C分别形成有贯通孔4E，外桶3内的水经由贯通孔4E能在外桶3与清洗桶4之间往来。由此，水以与外桶3相同的水位的方式从底板部4C侧蓄积在内部空间10。形成于底板部4C的多个贯通孔4E在偏向旋转轴线J侧即径向内侧R1的位置，隔有间隔地配置在周向S上。
在圆周壁4B中从径向外侧R2对内部空间10进行区划的内周面4F的上端部装配有环状的平衡器11。平衡器11减轻旋转时的清洗桶4的振动，在平衡器11的内部的空腔11A收纳有用于有助于减轻振动的液体。在底部4D的底板部4C的上表面形成有向下侧Z2越发凹陷的凹状的配置区域12。配置区域12是与底板部4C呈同轴状、在上下扁平的圆筒状的空间。配置区域12处于从径向外侧R2被构成底部4D的圆周壁4B的下端部包围的状态。
分隔构件5形成为具有与旋转轴线J一致的中心轴线的圆板状，是在水平方向H上平坦的盖，以从上侧Z1覆盖配置区域12的几乎整个区域的状态装配于清洗桶4的底部4D。清洗桶4的内部空间10处于通过分隔构件5在上下被分隔成配置区域12和位于配置区域12的上侧Z1的清洗区域13的状态。配置区域12是占据内部空间10的下端部的微小区域，而清洗区域13是占据大部分内部空间10的区域，在清洗区域13配置有清洗对象Q。
在分隔构件5的远离旋转轴线J的外周部以在周向S上隔有间隔的方式形成有多个连通口5A(参照图2)。各连通口5A处于在上下方向Z贯通分隔构件5的外周部，使配置区域12的外周部与清洗区域13连通的状态。需要说明的是，既可以在各连通口5A设置格子5B，也可以在分隔构件5的旋转轴线J侧统一形成有多个贯通孔5C(参照图2)。
抽水构件6形成为向径向内侧R1膨出并在上下方向Z延伸的槽状，从径向内侧R1装配于清洗桶4的圆周壁4B的内周面4F。抽水构件6的上端从下侧 Z2连结于平衡器11。可以设置有多个抽水构件6，在该情况下，多个抽水构件6配置为：排列在周向S上。在抽水构件6的径向内侧R1的侧面的上端部以从径向内侧R1面向旋转轴线J的方式形成有例如在周向S上延伸的狭缝状的排出口6A。在抽水构件6与内周面4F之间形成有在上下方向Z上延伸的抽水路14。抽水路14的上端部从排出口6A向径向内侧R1露出。将抽水路14的下端称为吸入口14A。吸入口14A从上侧Z1连接于配置区域12的外周部的未被分隔构件5覆盖的部分。
在清洗桶4的底部4D的从径向外侧R2对配置区域12进行区划的部分、详细而言在圆周壁4B的下端部形成有引导部4G。引导部4G是随着朝向上侧Z1而向径向外侧R2凸起的弯曲面，从径向外侧R2面向配置区域12的外周部。引导部4G至少设置于底部4D的在周向S上与分隔构件5的各连通口5A以及抽水路14的吸入口14A相同的位置即可，但也可以设置于周向S上的底部4D的整个区域。位于在周向S上与连通口5A相同位置的引导部4G的上端从下侧Z2连接于该连通口5A。位于在周向S上与吸入口14A相同位置的引导部4G的上端从下侧Z2连接于该吸入口14A。
电机7在壳体2内配置于外桶3的底壁3C的下侧Z2。电机7的输出轴分支成向上侧Z1延伸的管状的第一传递轴15、以及具有游隙地插通于第一传递轴15的第二传递轴16。电机7能通过经由公知的变速机构17将驱动力有选择地从第一传递轴15以及第二传递轴16的任一个输出。
第一传递轴15向上侧Z1延伸，贯通底壁3C的圆心，连接于清洗桶4的底板部4C的圆心。第一传递轴15的上端部具有呈凸缘状突出的凸缘部15A，凸缘部15A从下侧Z2固定于底板部4C，由此与清洗桶4连结。当驱动电机7将驱动力传递至第一传递轴15时，清洗桶4绕旋转轴线J旋转。
水流产生构件8在分隔构件5的下侧Z2的配置区域12中，在与清洗桶4的底部4D以及分隔构件5这两方不接触的状态下，配置于清洗桶4的底板部4C的上侧Z1。清洗桶4的内部空间10处于被分隔为配置有水流产生构件8的配置区域12、以及在分隔构件5的上侧Z1配置有清洗对象Q的清洗区域13的状态，因此能防止清洗区域13的清洗对象Q与旋转中的水流产生构件8接触而损伤清洗对象Q。由此，能提高水流产生构件8的转速。水流产生构件8装配 于第二传递轴16的向凸缘部15A的上侧Z1露出的上端部16A。水流产生构件8具有顶板部20以及多个叶片部21。
顶板部20是平板状，详细而言，是具有与旋转轴线J一致的中心轴线的圆板状，具有与清洗桶4的底板部4C的板厚方向一致或者大致一致的板厚方向。就是说，顶板部20的板厚方向是与上下方向Z一致或者大致一致的方向。顶板部20的下表面部20A以及上表面部20B这双方沿着水平方向H为平坦。顶板部20的外径与分隔构件5的外径几乎相同。顶板部20从下侧Z2邻接于分隔构件5，并且呈平行的状态配置。在下表面部20A的与旋转轴线J一致的圆心上设有向下侧Z2突出的筒状的连结部22。在连结部22从下侧Z2插入有第二传递轴16的上端部16A，连结部22通过螺栓等止动构件与上端部16A连结。
参照图3，多个叶片部21为在周向S上薄、以远离旋转轴线J的方式向径向外侧R2呈放射状延伸的叶片，在顶板部20的下表面部20A设置为：在周向S上排列。这些叶片部21包括在周向S上交替地排列的第一叶片部23以及第二叶片部24。第二叶片部24在径向R上比第一叶片部23短。各第一叶片部23的径向外侧R2的端缘23A和各第二叶片部24的径向外侧R2的端缘24A以与顶板部20的外周缘20C一致的方式在径向R上配置于相同位置。另一方面，各第一叶片部23的径向内侧R1的端缘23B和各第二叶片部24的径向内侧R1的端缘24B配置为：从连结部22远离径向外侧R2，但端缘24B配置为：相比于端缘23B偏向径向外侧R2。
在顶板部20的下表面部20A设有从径向外侧R2被端缘23B以及端缘24B包围的圆柱状的空间。将该空间称为引入空间25。连结部22位于引入空间25的中心。在下表面部20A设有夹在周向S上相邻的叶片部21之间、就是说夹在相邻的第一叶片部23以及第二叶片部24之间的水路26。存在多个水路26，配置为：在周向S上排列。各水路26从径向外侧R2与引入空间25连通，形成为：从引入空间25向径向外侧R2呈放射状延伸。各水路26的径向外侧R2的端部是向径向外侧R2露出的出口26A。
参照对图1中的水流产生构件8以及其周边进行放大示出的图4，各水路26处于从上侧Z1被顶板部20堵住的状态。另一方面，各叶片部21处于以不接触的方式从上侧Z1与清洗桶4的底板部4C对置的状态。因此，各水路26从上 侧Z1与底板部4C对置，但不是从下侧Z2被底板部4C堵住的状态。引入空间25处于从上侧Z1与底板部4C的旋转轴线J侧的贯通孔4E对置的状态。形成于清洗桶4的底部4D的引导部4G从径向外侧R2邻接于水流产生构件8，始终处于从径向外侧R2至少与任一水路26的出口26A对置的状态。
在外桶3以及清洗桶4蓄积有水的状态下，配置区域12内的水流产生构件8处于浸于水中的状态。当以该状态驱动电机7时，电机7的驱动力从第二传递轴16传递至水流产生构件8，由此水流产生构件8绕旋转轴线J旋转。在水流产生构件8旋转时，清洗桶4处于停止的状态。如实线的箭头所示，存在于引入空间25的水通过由水流产生构件8的旋转产生的离心力流入各水路26，以远离旋转轴线J的方式在各水路26中流动。存在于配置区域12的水流产生构件8的下侧Z2的水受各水路26中的流动的影响，以远离旋转轴线J的方式流动。如此，当配置区域12的水流动时，如虚线的箭头所示，存在于径向R的外桶3的圆周壁3B与清洗桶4的圆周壁4B的间隙27的水受旋转的水流产生构件8的影响，穿过间隙27下降，在到达外桶3的底壁3C与清洗桶4的底板部4C的间隙28后，从底板部4C的贯通孔4E被引入配置区域12。
从引入空间25流入各水路26的水、在配置区域12的水流产生构件8的下侧Z2以远离旋转轴线J的方式流动的水，通过由水流产生构件8的旋转产生的离心力向水流产生构件8的径向外侧R2流动，通过位于其前方的引导部4G，朝向分隔构件5的连通口5A或者抽水路14的吸入口14A导向上侧Z1。如单点划线的箭头所示，导向连通口5A的水被伴随着水流产生构件8的旋转的后续的水推动，由此从连通口5A朝向上侧Z1大力地喷出直至清洗区域13。如双点划线的箭头所示，导向抽水路14的吸入口14A的水被伴随着水流产生构件8的旋转的后续的水推动，由此从吸入口14A流入至抽水路14内，在抽水路14内上升，从抽水构件6的排出口6A大力地喷出，降至清洗区域13内(参照图1)。如此，通过随着水流产生构件8的旋转从连通口5A以及排出口6A喷出至清洗区域13的水，在清洗区域13产生水流。该水流喷向内部空间10的清洗对象Q，或者搅拌清洗对象Q，由此对清洗对象Q进行清洗。
在清洗区域13的水从清洗桶4的圆周壁4B的贯通孔4E流出至外桶3的圆周壁3B与清洗桶4的圆周壁4B的间隙27后，通过旋转的水流产生构件8被引 入至配置区域12之后，再次向清洗区域13喷出。就是说，在水流产生构件8的旋转过程中，清洗桶4的内部空间10中的水在配置区域12与清洗区域13之间循环。需要说明的是，在对清洗对象Q进行清洗之后，在水流产生构件8停止的状态下清洗桶4旋转，也可以通过其离心力对清洗对象Q进行脱水。
在以上说明的清洗机1中，水流产生构件8的顶板部20是具有与底板部4C的板厚方向一致或者大致一致的板厚方向的平板状，因此能在底板部4C的板厚方向就是说上下方向Z较小地构成整个水流产生构件8。由此，在清洗桶4的内部空间10中，能将水流产生构件8的配置区域12抑制得较小，另一方面，能确保清洗对象Q的清洗区域13较宽，因此，在清洗区域13中能使水流充分地泼向清洗对象Q。因此，能够谋求提高清洗力。此外，如上所述能提高水流产生构件8的转速，因此能够谋求进一步提高清洗力。
此外，通过这些第一叶片部23之间的第二叶片部24能将在周向S上夹在相邻的第一叶片部23之间的空间U分割成即使在远离旋转轴线J的位置周向S的尺寸也不太变化的两个水路26(参照图3)。因此，通过分成两个在周向S上狭窄的水路26，能使从旋转轴线J侧流入该空间U的水以维持高水压的状态从各水路26流出。由此，在洗涤桶的内部空间10产生流势强的水流，通过该水流能有效地对清洗对象Q进行清洗，因此能够谋求进一步提高清洗力。此外，通过将多个叶片部21构成为：在径向R上的长度不同的第一叶片部23和第二叶片部24交替地排列，能使叶片部21的形状简单化。
此外，第二叶片部24的径向内侧R1的端缘24B配置为：相比于第一叶片部23的径向内侧R1的端缘23B偏向径向外侧R2(参照图3)。由此，在相邻的第一叶片部23之间的径向内侧R1的端缘23B之间，能确保用于大量地接受将要从旋转轴线J侧流入至各水路26的水的空间V(参照图3)。由此，能使大量的水在各水路26中不间断地流动，在洗涤桶的内部空间10持续并有效地产生流势强的水流。因此，能通过该水流有效地对清洗对象Q进行清洗，因此能够谋求进一步提高清洗力。
此外，当形成于清洗桶4的底部4D的引导部4G从水路26的出口26A接受在水路26中流向径向外侧R2的水时，迅速地导向引导部4G的正上方的连通口5A，因此能缩短从水路26到连通口5A的路径。此外，当其他引导部4G从 水路26的出口26A接受在水路26中流向径向外侧R2的水时，迅速地导向引导部4G的正上方的吸入口14A，因此能缩短从水路26到吸入口14A就是说抽水路14的路径。因此，在水路26中流动的水能以维持高水压的状态迅速地到达清洗区域13，因此，在清洗区域13中高效地产生强水流，通过该水流能有效地对清洗对象Q进行清洗。由此，能够谋求进一步提高清洗力。引导部4G不是单独的零件，而是形成于清洗桶4的底部4D，因此能够谋求削减零件件数。
本发明并不局限于以上说明的实施方式，能够在权利要求记载的范围内进行各种变更。
图5是从下侧Z2观察变形例的水流产生构件8的立体图，图6是在适用了该水流产生构件8的清洗机1的内部构造的纵剖面图中，表示与图4对应的部分的主要部分放大图。图7是其他变形例的水流产生构件8的纵剖面图。在图5～图7中，对与以上说明的部分相同的部分赋予相同的附图标记，省略关于该部分的说明。
参照图5，水流产生构件8可以进一步包括闭塞部30。闭塞部30形成为圆盘状，以同轴状从下侧Z2对置地配置于顶板部20。闭塞部30从下侧Z2连接于各叶片部21的下端的径向R的整个区域。由此，夹在相邻的叶片部21的各水路26处于从下侧Z2被闭塞部30堵住的状态。图5的闭塞部30是与顶板部20平行的平板状，因此，夹在相邻的叶片部21的水路26的上下方向Z的尺寸在径向R的整个区域是固定的。闭塞部30的外径与顶板部20的外径几乎相同，第一叶片部23的径向外侧R2的端缘23A和第二叶片部24的径向外侧R2的端缘24A与闭塞部30的外周缘30A一致。
在闭塞部30的旋转轴线J侧的区域、详细而言在闭塞部30的圆心形成有在上下方向Z贯通闭塞部30的圆形状的引入口30B。闭塞部30的对引入口30B进行加边并在周向S上延伸的内周缘30C位于第一叶片部23的径向内侧R1的端缘23B、以及第二叶片部24的径向内侧R1的端缘24B的径向内侧R1。引入口30B位于顶板部20的下表面部20A的连结部22以及引入空间25的下侧Z2。
参照图6，从电机7引出的第二传递轴16的上端部16A从下侧Z2插通于闭塞部30的引入口30B，与顶板部20的连结部22连结。当驱动电机7时，水流产生构件8绕旋转轴线J旋转。如粗虚线箭头所示，随着水流产生构件8的旋 转，闭塞部30的下侧Z2的水从引入口30B引入至引入空间25，然后，如实线的箭头所示，通过离心力进入各水路26，以远离旋转轴线J的方式在水路26中流动。如单点划线以及双点划线的箭头所示，如上所述，在水路26中流动的水从分隔构件5的连通口5A以及抽水构件6的排出口6A喷出至清洗区域13，由此在清洗区域13中产生水流。
在图1～图4中所说明的水流产生构件8中的各水路26未处于从下侧Z2被底板部4C堵住的状态，因此有可能根据水流产生构件8和底板部4C的安装误差导致各水路26的上下的尺寸不均。但是，在变形例的水流产生构件8中，闭塞部30从下侧Z2堵住水路26，因此各水路26的上下的尺寸是稳定的，除了径向R的两端部以外，各水路26呈被密封的状态。由此，各水路26内的水不会在中途从水路26流出，而能以维持高水压的状态流至水路26的径向外侧R2的出口26A。因此，通过从水路26的出口26A流出的水，在清洗桶4的内部空间10高效地产生水势强的水流，能通过该水流有效地对清洗对象Q进行清洗，能够谋求进一步提高清洗力。
此外，由于第二传递轴16不与闭塞部30连结，而是与顶板部20连结，因此在闭塞部30的旋转轴线J侧的区域，能形成大引入口30B。由此，通过将大量的水从引入口30B引入至各水路26，能在清洗桶4的内部空间10高效地产生流势强的水流。因此，能通过该水流有效地对清洗对象Q进行清洗，能够谋求进一步提高清洗力。
如图7所示，闭塞部30可以不是与顶板部20平行的平板状，以随着朝向径向外侧R2而偏向上侧Z1的方式弯曲。由此，各水路26随着朝向径向外侧R2而在上下缩小，因此能进一步增强在水路26中流向径向外侧R2的水势。
水流产生构件8中的多个叶片部21可以不是沿着径向R的直线状，也可以形成为随着朝向径向外侧R2偏向周向S的一方的弯曲状或S字状。
旋转轴线J可以配置成相对于上下方向Z倾斜，在该情况下，通过将分隔构件5以及水流产生构件8配置成相对于水平方向H倾斜，维持与旋转轴线J正交的姿势。
