需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。
例如，一种洗衣机洗涤桶组件，所述洗衣机洗涤桶组件包括：大桶、大桶波轮、小桶、小桶波轮及三动力离合器；所述大桶的底壁上开设有大桶穿设孔；所述大桶波轮位于所述大桶内，所述大桶波轮上开设有大桶波轮穿设孔；所述小桶设置于所述大桶波轮上，且所述小桶位于所述大桶内，所述小桶的底壁上开设有小桶安装孔；所述小桶波轮位于所述小桶内；所述三动力离合器具有三个同轴的动力输出轴，由外往内分别为第一动力输出轴、第二动力输出轴及第三动力输出轴，所述第一动力输出轴连接所述大桶，所述第一动力输出轴用于带动所述大桶转动；所述第二动力输出轴穿过所述大桶穿设孔并连接所述大桶波轮，所述第二动力输出轴用于带动所述大桶波轮转动，所述大桶波轮用于在所述第二动力输出轴的带动下带动所述小桶转动，所述第三动力输出轴依次穿过所述大桶穿设孔、大桶波轮穿设孔和所述小桶安装孔并连接所述小桶波轮，所述第三动力输出轴用于带动所述小桶波轮转动。在其中一个实施例中，洗衣机洗涤桶组件包括下面各实施例的相关结构，包括但不限于大桶、大桶波轮、小桶、小桶波轮及三动力离合器等。
为了进一步说明上述洗衣机洗涤桶组件，又一个例子是，请参阅图1至图3，一种洗衣机，包括外桶、大桶110、大桶波轮120、小桶130、小桶波轮140及驱动装置，大桶110容置于外桶中，大桶波轮120容置于大桶110中，小桶130设置于大桶波轮120上，且小桶130容置于大桶110中，小桶波轮140容置于小桶130中。驱动装置用于分别驱动大桶110、大桶波轮120、小桶130及小桶波轮140转动，驱动装置具有传动轴，不同的传动轴分别对应大桶、大桶波轮及小桶波轮，来实现单独带动大桶、大桶波轮及小桶波轮旋转。
需要说明的是，本实施例中的外桶，起到整体支撑及安装作用。例如，洗衣机还包括箱体，外桶位于箱体内。外桶及箱体的具体设置请参阅现有技术。本实施例中的大桶，即相当于传统波轮洗衣机的洗涤桶，用来洗涤衣物。当洗衣机仅包括外桶、大桶及大桶波轮 时，其即类似于传统普通的波轮洗衣机，大桶内的衣物主要通过大桶波轮来扰动水流，结合大桶内侧壁上凸设的筋来完成对衣物的清洗。本实施例中的小桶，其为在传统普通波轮洗衣机的基础上增设的小桶，小桶安装设置在大桶波轮上，小桶可用于洗涤一些特殊衣物，如洗涤内衣、袜子、婴幼儿衣物等需要分离洗涤的衣物。如此，可以避免衣物清洗时的交叉污染。传统小桶的设计可以参阅如专利文献CN105483974A中的小桶。本申请的其它实施例中，也提出了对传统小桶进行改进的技术设计。
需要说明的是，申请人在如CN107059318A的图1所示的桶中桶洗衣机(即在现有普通波轮洗衣机的内桶中再增设一个小型内桶的洗衣机)中，采用DD(direct driver，直接驱动)变频电机来分别驱动大桶及大桶波轮转动。但如此的产品设计，DD变频电机本身结构复杂且成本较高，推高了整机成本，使桶中桶洗衣机售价偏高，因价格因素而使得桶中桶洗衣机较难服务于大众。为了降低传统桶中桶洗衣机成本，一实施例中，驱动装置为三动力离合器150，三动力离合器150设置于外桶的底壁外侧上。当然，三动力离合器也可以不固定在外桶的底壁外侧上。本实施例通过采用的三动力离合器结合传统普通电机，能够大幅降低洗衣机的成本。具体的，请参阅图4，三动力离合器150具有三个同轴的动力输出轴，由往外内分别为第一动力输出轴151、第二动力输出轴152及第三动力输出轴153。例如，三个同轴的动力输出轴由外往内顺序套置且可分别独立转动。第一动力输出轴151用于带动大桶110旋转，第二动力输出轴152用于带动大桶波轮120旋转。为了便于三动力离合器的三个动力轴能够穿过外桶底壁，例如，外桶的底壁上开设有外桶安装孔，三动力离合器固定于外桶的底壁外侧上，三动力离合器的三个动力输出轴均穿过外桶安装孔。需要说明的是，上述三动力离合器及用于驱动三动力离合器的普通电机，可从市场购买得到。例如，请参阅图2，三动力离合器150上具有传动齿轮154，普通电机通过皮带带动三动力离合器的传动齿轮，以为三动力离合器提供能力。当然，普通电机为区别于DD电机的电机或称为具有旋转轴的旋转电机。

为了较好地实现第一动力输出轴与大桶法兰盘的固定连接，一实施例中，请参阅图4，第一动力输出轴151外固定有第一轴承圈1511，请结合图5及图6，第一轴承圈1511与大桶法兰盘180远离大桶110的一面固定连接。具体的，第一轴承圈1511上开设有若干固定孔，大桶法兰盘180上开设有若干与第一轴承圈上的固定孔相对应的通孔182，第一轴承圈的若干固定孔与大桶法兰盘上的若干通孔分别通过一螺丝相固定，例如，第一轴承圈1511的若干固定孔以第一动力输出轴为中心呈圆形阵列分布，如此，能够较好地实现第一动力输出轴与大桶法兰盘的固定连接。一实施例中，请参阅图6，大桶法兰盘180开设有大桶法兰盘穿设孔181，请再次参阅图3，大桶110的底壁开设有大桶穿设孔111， 大桶法兰盘穿设孔181与大桶穿设孔111相对设置，以便于第二动力输出轴152和第三动力输出轴153能够穿过大桶波轮法兰盘180和大桶110的底壁。又如，大桶法兰盘180的中部开设有大桶法兰盘穿设孔。
请参阅图6并结合图5，大桶法兰盘180的中部向上凸出，或者说略为向上凸出，即往大桶110的高度方向向上凸出，大桶法兰盘穿设孔181及若干通孔182均设置于大桶法兰盘180的凸出区域，若干穿孔183均设置于大桶法兰盘180的未凸出区域。如此，通过将大桶法兰盘的中部向上凸出，能够使得大桶法兰盘180与第一动力输出轴151的安装位置更接近于大桶安装孔111，进而使得第二动力输出轴152和第三动力输出轴153伸入大桶180的内部的长度更长，便于后续大桶波轮及小桶波轮的安装。又如，大桶法兰盘穿设孔为圆孔结构。
请再次参阅图1，大桶波轮120位于大桶110内。具体的，大桶波轮120邻近大桶的底壁设置。请参阅图5并结合图3和图4，第二动力输出轴152穿过大桶穿设孔111并连接大桶波轮120，第二动力输出轴152用于带动大桶波轮120转动。大桶波轮主要用于扰动水流以清洗大桶内的衣物。例如，第二动力输出轴与大桶波轮固定连接。
为了较好地实现第二动力输出轴152与大桶波轮120的连接，一实施例中，请参阅图7并结合图5，洗衣机还包括大桶波轮法兰盘190，大桶波轮法兰盘190与大桶波轮120靠近大桶110的底壁的侧面固定连接，第二动力输出轴150连接大桶波轮法兰盘190，以实现通过大桶波轮法兰盘190带动大桶波轮转动。为了较好地实现大桶波轮法兰盘与大桶波轮的连接，一实施例中，大桶波轮法兰盘190开设有若干穿设孔192，大桶波轮120邻近大桶110的底壁的一侧开设有若干与穿设孔192相对应的大桶螺孔，各穿设孔192和各大桶螺孔分别通过一螺丝一一对应相固定。如此，能够较好地实现大桶波轮盘与大桶波轮的连接。例如，大桶波轮法兰盘190呈星形结构，大桶波轮法兰盘190的若干个端角位置处均设置有穿设孔192，如此，星形结构的大桶波轮法兰盘190，能够使得大桶波轮盘与大桶波轮的连接更为牢固。为了较好地实现第二动力输出轴152与大桶波轮法兰盘的固定连接，便于力矩的传送，一实施例中，请参阅图7、图4及图5，大桶波轮法兰盘190开设有紧固孔191，第二动力输出轴152支承在紧固孔191内，第二动力输出轴用于通过大桶波轮法兰盘带动大桶波轮转动。又如，紧固孔191具有非圆孔结构，又如，紧固孔191具有多边形孔结构，又如，紧固孔191具有八边形孔结构，又如，大桶波轮法兰盘的中部开设有紧固孔。如此，便于力矩的传送。请参阅图4，第二动力输出轴152外固定有限位圈1521，且第二动力输出轴152的端部伸出限位圈1521，第二动力输出轴152伸出限位圈1521的部分包括相连接的紧固部1522及螺接部1523，紧固部1522邻近限位圈1521设置，大桶波轮法兰盘190通过紧固孔191固定在紧固部1522外，且大桶波轮法兰盘190与限位圈1521抵接，螺接部1523外螺接有固定螺圈(图未示)，固定螺圈与大桶波轮法兰盘190抵接，第二动力输出轴152用于通过大桶波轮法兰盘190带动大桶波轮120转动。如此，限位圈1521和固定螺圈能够较好地将大桶波轮法兰盘190固定在第二动力输出轴152外。又如，紧固部1522的形状与紧固孔191的形状相匹配。请结合图7及图5，所以大桶波轮法兰盘190的中部向下凹陷，波轮法兰盘承载孔191位于大桶波轮法兰盘190的凹陷区域，如此，略为向下凹陷的大桶波轮法兰盘190，能够将大桶波轮法兰盘与第二动力输出轴的连接位置更为向大桶110的底壁移动，便于节省大桶内的空间，且如此，也便于使得螺接部1523具有更长的长度以设置更多的螺纹，从而使得螺接部1523和固定螺圈的连接更为紧固。又如，固定螺圈的高度和螺接部的长度一致，如此，第二动力输出轴与大桶波轮法兰盘安装后的紧固性更好。
为了便于第三动力输出轴153通过大桶波轮120，请参阅图3，大桶波轮120开设有大桶波轮穿设孔1212，以便于第三动力轴穿过或者通过其他部件连接其上方的小桶波轮。请再次参阅图8，大桶波轮120上设置有若干凸筋122，大桶波轮120的若干凸筋122以 大桶波轮120的转动中心呈圆形阵列分布，如此，大桶波轮上的凸筋起到水流扰动作用以便于大桶内的衣物的清洗。又如，大桶波轮沿其径向方向开设凸筋。又如，大桶波轮120的凸筋122具有相背的第一拨水面1221和第二拨水面1222，第一拨水面沿大桶波轮的径向方向具有相对的两端，第一拨水面自其两端向其中部逐渐向远离第二拨水面的方向凸起，第二拨水面沿大桶波轮的径向方向具有相对的两端，第二拨水面自其两端向其中部逐渐向远离第一拨水面的方向凸起，如此，稍向外侧凸起的第一拨水面和第二拨水面，能够提高大桶波轮的水流扰动效果，使得大桶波轮正转、反转均具有较好的水流扰动效果。又如，大桶波轮120的凸筋的第一拨水面和第二拨水面呈左右对称设置。
请参阅图2及图5，小桶130设置于大桶波轮120上，且小桶130位于大桶110内。大桶波轮120用于在第二动力输出轴152的带动下带动小桶130转动。例如，小桶130可拆卸设置于大桶波轮120上。如此，方便小桶的拆卸。例如，将小桶与大桶波轮的可拆卸方式可以包括但不限于卡接、卡扣、螺接、捆绑、捆接、嵌套等。为了便于小桶和大桶波轮的安装和拆卸，一实施例中，请参阅图8、图9并结合图5，大桶波轮120凸设有定位柱121，小桶130的底壁外侧上凹设有定位槽131，定位柱121嵌置于或者插设于定位槽131内，大桶波轮120的定位柱121用于在大桶波轮120转动时带动小桶130转动。需要说明的是，本实施例中的定位槽也可以理解为凹设结构，即，小桶的底壁外侧开设有凹设结构。需要说明的是，本申请的定位槽或者定位柱，如前的“定位”等字样，是为了方便描述，而不是用于限制其具体结构。后续相关术语以此类推，或者也应作此理解。本实施例中，通过定位柱121与定位槽131的设置，便于在需要使用到小桶时，通过定位柱和定位槽的配合将小桶130安装在大桶波轮120上。为了较好地实现定位柱与定位槽的安装，并便于大桶波轮带动小桶转动的力矩传送，例如，定位槽的形状与定位柱的形状相匹配。又如，定位柱的形状或者说截面形状设置成三角形、四边形及其它多边形或者非圆形形状，如此便于通过大桶波轮通过定位柱和定位槽的配合来带动小桶转动。当然，其它实施例中，定位柱截面的形状也可以设置为圆形。能够理解的是，设置成圆形截面的定位柱，相对于非圆形状的截面的定位柱，更容易对准，能够使得定位柱与定位槽的安装更为便捷，进而方便小桶的安装和拆卸。
需要说明的是，常规的桶中桶洗衣机，即在现有普通波轮洗衣机的内桶中再增设一个小型内桶的洗衣机，在将小桶通过定位柱与凹槽的方式安装至大桶波轮上时，结构牢固性较差，在使用小桶清洗时，若洗衣机震动过大可能会出现小桶脱落的情况。为了使得小桶安装至大桶波轮上后结构牢固性较好以及小桶不易脱落，一实施例中，请再次参阅图8、图9并结合图12，定位柱121的外侧壁上开设有若干插槽1211，即便于后续限位插柱插入的槽，小桶130于其定位槽131的内侧壁上设置有若干限位插柱1311，限位插柱1311至少部分嵌置于或者插设于插槽1211内。如此，由于定位柱嵌置于定位槽内，且通过限位插柱与插槽的配合，使得小桶安装至大桶波轮上后结构牢固性较好，小桶不易脱落。又如，请参阅图8及图9，定位柱121设置在大桶波轮120的中部。当然，其它实施例中，也可以将定位柱或者定位槽设置多个并分别设置在大桶波轮上的多个位置。本实施例中，如图8所示，定位柱及定位槽的数量均为一个。通过将定位柱121设置在大桶波轮120的中部，能够使得小桶的安装便捷性较好。又如，如图8及图9所示，定位柱121沿小桶高度方向具有圆形截面，或者说其外侧壁具有圆形截面。定位槽131沿小桶高度方向具有圆形截面。如此，通过将定位柱设计成圆形截面，并结合限位插柱与插槽的配合，使得小桶安装至大桶波轮上后结构牢固性较好，从而使得小桶不易脱落。例如，限位插柱与插槽相互配合并限位以使大桶波轮在转动时带动小桶转动。如此，便于大桶波轮通过限位插柱和插槽的配合以带动小桶转动。又如，插槽的形状与其对应的限位插柱的形状相匹配。又如，限位插柱1311一一对应嵌置于插槽1211内。如此，通过限位插柱1311与插槽1211的配合，能够进一步提高小桶安装至大桶波轮后的结构牢固性，使得小桶使用过程中不易脱落。 一实施例中，限位插柱1311具有长方体结构，插槽1211具有矩形截面，又如，限位插柱1311为条形凸起结构，插槽1211具有与限位插柱1311相匹配的边界面，限位插柱1311与插槽1211形成间隙配合。如此，限位插住1311插入插槽中后具有更好的限位作用，使得小桶安装至大桶波轮上后结构牢固性更好。例如，定位柱的高度为40毫米至110毫米，定位槽沿小桶高度方向的深度为60毫米至110毫米。如此，能够使得定位柱与定位槽的结合强度较好，减少或者避免小桶脱落。当然，定位槽的深度或者定位柱的高度并不限于此。又如，定位柱的高度为45毫米至60毫米，定位槽沿小桶高度方向的深度为75毫米至90毫米。如此，能在尽量减少定位柱与定位槽的高度的情况下保证其结合力。当然，具体实施例中，定位柱的高度和定位槽的高度需要可根据桶的大小以及转速等进行灵活设置。例如，插槽1211沿大桶波轮的径向方向的深度为1.5毫米至20毫米。又如，插槽沿大桶波轮的径向方向的深度为1.8毫米至3毫米。又如，插槽沿小桶高度方向的深度为15毫米至80毫米。又如，插槽沿小桶高度方向的深度为15毫米至80毫米。又如，插槽沿小桶高度方向的深度为20毫米至25毫米。又如，限位插柱沿小桶高度方向的长度为40毫米至100毫米。又如，限位插柱沿小桶高度方向的长度50毫米至70毫米。如此，能够较好地保证插槽与插柱的结合强度，便于大桶波轮的力矩的传送。一个具体的例子是，定位槽的深度为77毫米，限位插柱的长度为77毫米，定位柱的高度为73毫米，插槽的长度为73毫米。如此，安装牢固性更好。当然，插槽和插柱也可以为其它可以相嵌套的结构，以使得定位柱嵌置于定位槽后通过插槽和插柱具有一定的限位作用即可。又如，若干插槽1211的设置位置以大桶波轮120的转动轴线呈间隔分布。又如，请参阅图8及图9，若干插槽1211的设置位置以大桶波轮120的转动轴线呈两两间隔分布。如此，能够使得小桶130与大桶波轮的安装强度更为牢固，使得大桶在脱水过程不易脱落。例如，定位槽131的深度大于小桶130的底壁的厚度，定位槽的深度即指定位槽沿小桶130高度方向的长度。
当大桶波轮上设置有凸筋122时，为了充分利用凸筋122的限位作用，以进一步提高小桶安装至大桶波轮后的结构牢固性，一实施例中，请参阅图8至图10，小桶130于其底壁外侧上设置有若干限位槽133，大桶波轮120的凸筋122嵌置于限位槽133内。又如，大桶波轮的若干凸筋与小桶的底壁上的限位槽133一一对应，且限位槽与其对应的凸筋的形状相匹配，如此，在将小桶130通过其定位槽131嵌置于定位柱121外安装至大桶波轮上时，小桶上的限位槽133也嵌置于凸筋外，进一步提高了小桶安装至大桶波轮后的结构牢固性，使得小桶在使用过程中不易脱落。又如，大桶波轮120的若干凸筋122以大桶波轮120的转动轴线呈圆形阵列分布。又如，大桶波轮的凸筋的数量为5个至12个。优选的，大桶波轮120的凸筋122的数量为5个。如此，一方面，其对大桶内的衣物清洗效果较好，另一方面其能够进一步提高了小桶安装至大桶波轮后的结构牢固性，使得小桶在使用过程中不易脱落。又如，请结合图8及图10，大桶波轮120整体呈圆形扁平结构。如此，扁平结构的大桶波轮更适宜于安装小桶，使得小桶能够较为牢固地安装在大桶波轮上。又如，请参阅图8，大桶波轮120于相邻两个凸筋122的中间还开设有若干排水孔123。又如，请参阅图9，大桶波轮远离小桶的一面还凸设有若干环形加强筋124及径向加强筋125，各径向加强筋分别与若干环形加强筋相交，如此，能够提高大桶波轮120的整体结构强度。一实施例中，请参阅图8及图12，大桶波轮的周缘向上凸起或者略为向上凸起，如此，略为向上凸起的周缘能够在一定程度上减少异物掉入大桶波轮下方，即掉入大桶波轮120与大桶110的底壁。为了进一步提高小桶安装至大桶波轮后的结构牢固性，避免大桶波轮带动小桶脱水旋转过程中，小桶出现脱落的问题，一实施例中，请参阅图11，其为简要示意图，限位插柱1311上设置有凸设部13111，定位柱于插槽1211的侧壁开设有凹设槽12111，当限位插柱1311嵌置于或者插设于插槽1211内时，凹设槽12111与凸设部13111的位置相对应，且凸设部13111可至少部分容置于凹设槽12111内，根据实际使 用过程中，可以将凹设槽的位置和凸设部的位置设置于小桶使用时脱水旋转过程中离心切向力朝向的那一侧，或者是脱水旋转过程中圆周力指向的那一侧。或者说，凹设槽的位置开设于限位插柱上小桶脱水旋转过程中离心切向力朝向的那一侧，凸设部的位置设置于插槽上小桶脱水旋转过程中离心切向力朝向的一侧的侧壁上。如此，通过设置凹设槽和凸设部，在脱水旋转过程中，在脱水离心切向力作用下，凸设部可至少部分容置于凹设槽内，使得凹设槽对凸设部具有一定的限位作用，从而使得插槽对插柱具有一定的限位作用，进而使得大桶波轮的定位柱对小桶的定位槽具有较好的限位作用，能够进一步提高小桶安装至大桶波轮后的结构牢固性，避免大桶波轮带动小桶脱水旋转过程中，小桶出现脱落的问题。在一具体实施例中，小桶的侧壁具有一定的倾斜角度，通常为1.5度～30度，在脱水旋转的离心力的作用下，使得小桶的水容易通过倾斜的侧壁被甩出，但是当脱水旋转的离心力过大时，存在小桶不稳定，甚至被甩出的风险。本实施例中，通过设置凹设槽12111和凸设部13111，能够较好地提高小桶安装至大桶波轮后的结构牢固性，在大桶波轮带动小桶脱水旋转过程中，提高小桶的稳定性。又如，凸设部13111具有长方体结构，凹设槽12111也具有矩形截面。或者说，凹设槽12111与凸设部13111的形状相匹配。当然，凸设部与凸设部也可以为其它形状，只要能够使插槽对限位插柱具有一定限位作用即可。为了减少大桶波轮带动大桶旋转时产生的噪音，一实施例中，插槽和限位插柱之间还具有橡胶条，如此，通过加装橡胶条，能够减少大桶波轮带动大桶旋转时产生的噪音。当然设置橡胶条时，在凹设槽或凸设部的位置适当使橡胶条避空。
需要说明的是，当大桶波轮的中部设置了定位柱时，大桶波轮上开设的大桶波轮穿设孔贯穿定位柱的顶部。如此，便于第三动力输出轴或者其传动部件穿过。当大桶波轮穿设孔贯穿定位柱远离大桶波轮的侧面后，且定位柱的外侧壁具有圆形截面时，也可以将此时的定位柱看成为空心圆柱体。为了便于第三动力输出轴153穿过小桶130的底壁，一实施例中，请参阅图3及图12，小桶130的底壁开设有小桶安装孔1312，如此，小桶安装孔1312便于第三动力轴153或者其传动部件穿过并伸入至小桶130内部，以连接位于小桶内部的小桶波轮140。又如，小桶130的底壁于定位槽131的底壁开设有小桶安装孔1312，小桶安装孔1312与大桶波轮穿设孔1212至少部分重合，如此，便于第三动力轴153或者其传动部件依次穿过大桶波轮穿设孔1212及小桶安装孔1312。
能够理解，小桶130的底壁通常较薄，在其上开设凹设结构或者定位槽131时，在技术设计上受限很多，影响小桶130安装在大桶波轮120上的牢固性。为了提高小桶130安装在大桶波轮120上的牢固性，一实施例中，请参阅图12并结合图5和图2，定位槽131于小桶130的底壁130a内侧形成有安装柱132，即，定位槽131在小桶的内侧底壁一侧形成有安装柱，也可理解为，小桶130的底壁130a内侧凸设有安装柱，安装柱132在小桶的底壁130a外侧形成有定位槽131。安装柱132远离小桶130的内侧底壁的一面开设有小桶安装孔1312。如此，凸设的安装柱132便于开设较长深度的定位槽131，进而能够提高小桶130安装在大桶波轮120上的牢固性。本实施例中，也可理解为，安装柱132设置于小桶120的底壁上，即将安装柱看成为分离于小桶的底壁部件。当然，需要说明的是，小桶的底壁凸设安装柱，或者说，安装柱设置于小桶的底壁上，虽然文字描述不同，但其均应该当作本申请囊括的范围。需要说明的是，小桶的底壁内侧，即为小桶的底壁于小桶内部的一侧，小桶的底壁外侧即为小桶的底壁与小桶外侧的一侧，其它以此类推。
请再次参阅图5并结合图1及图3，小桶波轮140位于小桶130内，第三动力输出轴153依次穿过大桶穿设孔111、大桶波轮穿设孔1212和小桶安装孔1312并连接小桶波轮140，第三动力输出轴153用于带动小桶波轮140转动。小桶波轮140用于提供扰动水流作用，以便于小桶内衣物的清洗。需要说明的是，传统的桶中桶洗衣机(即在现有普通波轮洗衣机的内桶中再增设一个小型内桶的洗衣机)依然存在如下缺陷：一方面，现有的桶中桶洗衣机主要通过DD(direct driver，直接驱动)变频电机驱动，DD变频电机本身结 构复杂且成本较高，推高了整机成本，使桶中桶洗衣机售价偏高，因价格因素而使得桶中桶洗衣机较难服务于大众。另一方面，现有的桶中桶洗衣机清洗效果较差，小桶内衣物的清洗主要依靠小桶内壁凸起的筋来实现水流扰动进行清洗，小桶内衣物的清洗主要依靠小桶内壁凸起的筋来实现水流扰动进行清洗，如此，衣物与水流之间的相对运动就相对较弱，对小桶中衣物的清洗效果也就较差。此外，传统的桶中桶洗衣机，大桶波轮的动力主要由DD电机的洗涤轴提供。DD电机动力输出轴分为洗涤轴与脱水轴，脱水轴驱动大桶转动，洗涤轴驱动波轮转动，洗涤轴强度较小，力臂较长。使用小桶洗涤时，洗涤轴所受扭矩和弯曲应力较大，间接就会导致固定洗涤轴的轴承磨损严重。由于洗涤轴强度受限，其能承受的最大力矩受限，体现到外在表现就是小桶洗涤时衣物与水的重量受制约，从而小桶的额定洗涤容量就不能太大。本实施例中，通过在采用三动力离合器150，其具有三个动力轴，相较于DD电机，其多出一个第三动力输出轴153，第三动力输出轴带动小桶波轮转动，如此，在使用小桶洗涤过程中，小桶的洗涤动力同时由第二动力输出轴和第三动力输出轴来提供，能够解决传统的上述问题，相对于现有的桶中桶洗衣机，本申请的洗衣机，由于小桶的洗涤动力同时由第二动力输出轴和第三动力输出轴来提供，带动大桶波轮的第二动力输出轴所受扭矩和弯曲应力相应减少，从而能够使小桶的额定洗涤容量得到提高，小桶能够洗涤更大容量的衣物。此外，在小桶内设置小桶波轮，相对于传统的桶中桶洗衣机，其小桶仅依靠洗涤内桶的内侧壁凸设的筋来实现水流扰动进行清洗的方式，上述洗涤内桶在小桶内设置小桶波轮，能够实现更强的水流扰动效果，从而能够提高对衣物的清洗效果。
能够理解，小桶130内的衣物清洗，其排水时，主要通过将小桶进行高速旋转，使其中的水从小桶倾斜的底壁被甩出。为了进一步介绍小桶，请参阅图12，小桶130包括底壁130a及侧壁130b，小桶的底壁连接小桶的侧壁，且小桶130的底壁130a和小桶130的侧壁130b共同围成小桶的中空腔体。如前的位于小桶内，即位于小桶的中空腔体内。安装柱132亦位于小桶130的中空腔体内。例如，小桶的侧壁具有倾斜角度，且小桶的内侧直径由小桶的底壁沿小桶的开口方向逐渐变大。例如，倾斜角度为1.5度至30度。如此，倾斜的小桶的侧壁能够在小桶中的衣服脱水过程中，能够较好地将水沿着小桶的侧壁甩出。例如，小桶130的底壁130a于小桶130的外侧开设有凹设结构，即如前的定位槽131，凹设结构用于将小桶可拆卸安装至大桶波轮上。例如，小桶130的底壁130a整体呈圆形结构，或者说，小桶的底壁130a沿小桶的高度方向具有圆形横截面。凹设结构131位于底壁130a的中部，且凹设结构131的位置与安装柱132的位置相对应，也可以理解为，凹设结构在小桶的底壁的内侧形成安装柱。例如，安装柱沿小桶高度方向具有圆形截面，例如，安装柱的直径为小桶最小直径的1/5～2/5。如此，小桶的清洗效果较好。能够理解的是，在小桶的底壁设置安装柱之后，安装柱突出小桶的底壁，会在一定程度上影响小桶波轮的安装，尤其是当小桶波轮140较平时，会浪费小桶内的不少空间。一实施例中，请参阅图12并结合图13，小桶130的侧壁130b与底壁130a之间设有第一台阶部130c和第二台阶部130d，第一台阶部130c包括相连接的顶壁130c1和侧壁130c2，第二台阶部130d包括相连接的顶壁130d1和侧壁130d2，第一台阶部的顶壁130c1连接小桶130的侧壁130b的内侧，第二台阶部的顶壁130d1连接第一台阶部的侧壁130c2，小桶130的底壁130a的周缘连接第二台阶部的底壁130d2。如此，设置第二台阶部除了可以容纳底壁上的限位槽133外，更重要的是可以保证安装柱的高度，使得安装柱具备足够的高度，从而底壁可以开设足够高度的定位槽和限位插柱，进而能够进一步提高小桶安装在大桶波轮上的结构强度，使得大桶波轮通过设置限位插柱和插槽驱动小桶旋转时可以保持稳定。此外，通过设置第一台阶部和第二台阶部，能够减少对小桶波轮安装的影响，能够减少小桶波轮与小桶的底壁之间的间隙空间的体积，进而减少小桶清洗时水的浪费。又如，第二台阶部的顶壁130d1连接第一台阶部的侧壁130c2的中部，如此，能够增加其结构连接强 度。又如，第一台阶部的侧壁130c2的顶端凸出第一台阶部的顶壁130c1，第一台阶部的侧壁130c2的顶端与第一台阶部的顶壁130c1和小桶的侧壁130b共同围成一第一环形挡物槽130e。又如，第二台阶部的侧壁130d2的顶端略凸出第二台阶部的顶壁130d1，第二台阶部的侧壁130d2的顶端与第二台阶部的顶壁130d1和第一台阶部的侧壁130c2共同围成一第二环形挡物槽130f，又如，小桶波轮140的下部周缘向下伸出有环形加强筋1431，小桶波轮140的下部周缘的环形加强筋1431至少部分容置于第二环形挡物槽130f内，如此，通过设置第一环形挡物槽以及第二环形挡物槽，同时将小桶波轮的下部周缘的环形加强筋至少部分容置于第二环形挡物槽内，能够对小桶清洗过程中的异物具有一定的阻挡作用，减少异物进入小桶波轮与小桶的底壁之间的空间内。例如，第一台阶部的高度为9毫米至13毫米，第二台阶部的高度为14毫米至21毫米。需要说明的是，第一台阶部及第二台阶部的高度均为其侧板的高度。为了方便将小桶拆卸和移动，一实施例中，小桶上设置有提手。如此，通过提手便于将小桶从大桶波轮上拆卸和移动。又如，提手设置于小桶的侧壁顶端。
为了进一步提高对小桶内衣物的清洗效果，例如，请参阅图12，小桶130的侧壁130b于内侧凸设有若干清洗筋130b1，又如，若干清洗筋130b1间隔分布于小桶的侧壁上，又如，若干小桶的清洗筋以小桶的旋转中心呈圆周间隔分布，如此，间隔设置的清洗筋能够进一步提高小桶内的水流扰动能力，进而能够提高对小桶内的衣物的清洗效果。又如，小桶的清洗筋为凸起长条结构，又如，清洗筋的长度延伸方向与小桶的高度方向相一致。如此，能够在小桶转动中，起到较好的水流扰动效果，进而能够提高对小桶内衣物的清洗效果。又如，小桶130的相邻两个清洗筋130b1的间隔圆心角为15度至20度，优选的，小桶的相邻两个清洗筋的间隔圆心角为20度。间隔圆心角为以小桶的旋转中心为中心的圆心角。如此，清洗效果更好。又如，小桶的清洗筋沿小桶的圆周方向的长度为8毫米至12毫米。又如，小桶的清洗筋的边角具有圆角结构。又如，小桶的清洗筋的边角均具有圆角结构。如此，对水流的扰动效果较好，能够提高对小桶内的衣物的清洗效果。
能够理解，衣物的清洗通常涉及浸泡、清洗及脱水等过程。倾斜的小桶的侧壁在小桶脱水过程中，其内的水顺着倾斜的侧壁而流至外桶中。但与此同时，在小桶进行正常清洗的过程中，旋转的小桶中的水流也会部分顺着小桶侧壁而流出。为了较好地在小桶清洗过程中对旋转的小桶的水起到挡水作用，例如，请参阅图14，其为一实施例中设置了挡水环的小桶的开口位置处的局部剖视图，小桶130的侧壁130b的顶部凸设有环形限位筋130b2，洗衣机还包括挡水环135，挡水环135包括相连接的挡水部1351及排水部1352，挡水部远离排水部的端部抵接环形限位筋，如此，环形限位筋对挡水部起到一定的支撑作用。挡水部由靠近环形限位筋的端部至远离环形限位筋的端部的直径逐渐变大，且排水部1351位于挡水部1352上方，排水部的直径由靠近挡水部的端部向远离挡水部的端部的直径逐渐变大，排水部远离述挡水部的端部伸出至小桶的侧壁外侧，排水部远离述挡水部的端部与小桶的侧壁顶端之间具有间隙，挡水部1351邻近环形限位筋的端部开设有若干排水孔13511，挡水部的排水孔以小桶的旋转中心呈圆周间隔分布，如此，通过设置挡水部，其对小桶非脱水状态下的清洗的水流具有较好的挡水作用，而当小桶脱水高速旋转过程中，小桶的水大部分可通过挡水部及排水部排放到小桶外面的大桶中，然后通过大桶进行排放。通过设置排水孔，能够较好地将挡水部远离排水部的端部处的小部分水排出。又如，挡水部的相邻两个排水孔的间距相等，又如，排水孔的开设方向为小桶的高度方向。又如，排水孔具有圆形截面，又如，排水孔由靠近小桶的底壁的一端向远离小桶的底壁的一端的直径之间变大。又如，排水孔的直径为4毫米至6毫米。又如，挡水部的相邻两个排水孔以小桶的旋转中心的圆心角为15度至20度。优选的，挡水部的相邻两个排水孔以小桶的旋转中心的圆心角为18度。如此，能够有效提高排水效率，且排水效果较好，能够使挡水部远离排水部的端部处的小部分水排放得较为彻底。又如，排水孔具有圆环横截面。为 了较好地起到挡水作用，减少水从挡水部与小桶的侧壁之间的间隙中通过，例如，挡水部1351远离排水部的端部还开设有环形槽13512，挡水部远离排水部的端部与限位筋之间还设置有密封圈136，密封圈部分容置于环形槽13512内，且密封圈与小桶的侧壁抵接。又如，密封圈为橡胶圈，如此，能够较好地密封挡水部的端部与小桶的侧壁之间的间隙。例如，洗衣机还包括压环137，压环137的顶端弯折形成有卡位槽1371，压环通过卡位槽1371扣在小桶的侧壁的顶端，压环的第二端与挡水部远离排水部的端部抵接，且挡水部远离排水部的端部位于压环和限位筋之间。如此，通过设置压环，能够较好地将挡水部抵持固定在环形限位筋上，进而使得整个挡水环的安装较为牢固。
能够理解，小桶可拆卸安装在大桶波轮上，如此，对于第三动力输出轴153与小桶波轮140的安装带来不小挑战。一方面，既要保证第三动力输出轴能够将力矩传递给小桶波轮，另一方面，要方便第三动力轴与小桶波轮的拆卸与安装。例如，第三动力输出轴可拆卸连接小桶波轮，具体的，包括但不限于螺接、卡接等方式。为了较为方便地使小桶波轮和第三动力轴可拆卸连接同时便于力矩的传送。一实施例中，洗衣机还包括动力输出轴连接组件，第三动力输出轴通过动力输出轴连接组件连接小桶波轮。请参阅图15至图19，动力输出轴连接组件包括上卡筒160及下卡筒170，上卡筒和下卡筒卡接。请参阅图16，上卡筒160开设有上卡牙161，下卡筒170开设有下卡牙171，上卡牙161和下卡牙171卡接，上卡筒160和下卡筒170通过上卡牙161和下卡牙171卡接而实现卡接。上卡筒160可用于安装连接待传动部件，下卡筒170用于安装连接驱动组件的动力输出轴或者传动轴。尤其是适合于可拆卸的小桶中小桶波轮和第三动力输出轴的可拆卸安装。具体本实施例中，上卡筒160可用于连接小桶波轮140，下卡筒170可用于连接第三动力输出轴153。上卡筒和下卡筒通过卡接来便于动力输出轴力矩的传送，以使第三动力输出轴通过下卡筒和上卡筒来带动小桶波轮转动。当需要将第三动力轴与小桶波轮断开时，直接将上卡筒和下卡筒的卡接断开即可。当将小桶安装在小桶波轮上时，上卡筒的上卡牙和下卡筒的下卡牙卡接。当将小桶从小桶波轮上拆卸时，上卡牙和下卡牙即可断开。
请参阅图15至图19，上卡筒160的外侧壁设置有上卡牙161；下卡筒170开设卡置槽172，下卡筒170的卡置槽内侧壁172设置有下卡牙171；上卡筒160至少部分容置于卡置槽172内，且上卡牙161和下卡牙172卡接。如此，能够使得上卡筒和下卡筒能够可拆卸连接，安装时，通过上卡牙和下卡牙的卡接来便于动力输出轴力矩的传送，具体的，本实施例中便于第三动力输出轴对小桶波轮的动力传送。拆卸时直接将上卡筒从下卡筒的卡置槽内拔出即可，从而使得安装过程和拆卸过程的操作都非常方便，操作便捷性较好。一实施例中，上卡牙161包括若干间隔分布于上卡筒160的外侧壁的上凸起1611，下卡牙171包括若干间隔分布于下卡筒170的卡置槽172的内侧壁的下凸起1711，相邻两个下凸起1711之间形成下凹槽1711a，各上凸起1611一一对应地插入一下凹槽1711a内，且每一上凸起1611至少部分插入于对应的下凹槽1711内。如此，安装结构牢固性较好，且力矩传送效率较高。又如，各上凸起一一对应地嵌置于一下凹槽内，且每一上凸起至少部分嵌置于对应的下凹槽内。如此，能够使得上卡牙和下卡牙的卡接更为牢固，进一步提高力矩传送效率。又如，上凸起1611及下凸起1711均具有条形结构，上凸起1611邻近下凹槽的端部具有尖角结构，下凸起111邻近上卡筒的端部也具有尖角结构。如此，端部的边角结构，更便于上凸起插入下凹槽内。需要说明的是，本实施例中，也可以理解为相邻两个上凸起之间形成上凹槽，各下凸起一一对应地插入一上凹槽内。应当理解的是，上述描述方式虽然有差异，但应将其囊入本申请的保护范围。此外，上卡筒和下卡筒的位置也可以调换，即，上卡筒用于连接动力轴，下卡筒用于连接待传动部件，如小桶波轮，其也应将其囊入本申请的保护范围。
一实施例中，请参阅图15至图19，上卡筒160包括顶板160a及筒体160b，筒体160b为空心圆柱状，筒体160b的外侧壁上设有上卡牙161，上卡牙161包括若干间隔分布于 筒体160b的外侧壁上的上凸起1611；顶板160a连接筒体160b的顶端。顶板用于开孔以安装连接小桶波轮。一实施例中，顶板160a连接上凸起1611远离下凹槽1711a的端部，如此，顶板能够使得筒体上的上凸起1611的结构更为牢固。又如，上卡筒160还包括安装杆160c，安装杆160c为圆柱状，顶板160a连接安装杆160c的顶端，安装杆160c的直径小于筒体160b的内侧直径，安装杆160c位于筒体160b内，筒体160b的长度小于安装杆160c的长度；如此，通过设置安装杆，便于在其中开设长度更长的孔，以便于使上卡筒和第三动力轴的安装连接更为牢固。一实施例中，各下凸起远离上卡筒的端部连接卡置槽的底壁。如此，能够其高整体下卡牙的结构强度。
一具体实施例中，上卡筒160通过花键221连接小桶波轮140，为了较好地将花键与上卡筒连接在一起，例如，请参阅图18，顶板160a上开设有上安置孔160a1，安装杆160c中开设有连通的上安装孔160c1及上容置孔160c2，上安置孔、上安装孔及上容置孔顺序连通；上安装孔的直径分别小于上安置孔和上容置孔的直径。上安置孔160a1用于容置花键221，上安置孔160a1与花键的形状相匹配。例如，花键邻近上卡筒的端部具有三角形、四边形或多边形截面，上安置孔与花键的形状相匹配，能够更便于力矩的传送。请结合图5，上安装孔160c1用于穿设螺丝310a的杆部，上容置孔160c2用于容置螺丝310a的头部。如此，能够使得上卡筒通过螺丝与花键相固定。当然，花键的端部需要开设与螺丝对应的螺孔。需要说明的是，本实施例中的螺丝310a，为了区别后续的螺丝，将其命名为第一上螺丝310a。例如，花键221的两端分别开设有两个螺孔，分别为花键上螺孔2211及花键下螺孔2212。例如，小桶波轮140上开设有固定孔141，小桶波轮140与花键221通过第二上螺丝310相固定。第二上螺丝310的杆部顺序螺接固定孔141及花键上螺孔2211。如此，能够将花键与小桶波轮进行连接。例如，第一上螺丝310a的杆部穿过上安装孔160c1并螺接花键下螺孔2212。如此，能够将花键与上卡筒连接。本实施例中的花键也可以理解为花键轴，或者连接杆。
请参阅图16及图18，下卡筒170于卡置槽172的底壁开设有安放槽1721，安装杆邻近下卡筒的端部容置于安放槽内，安放槽即用于安放或者放置或者容纳安装杆的端部。又如，下卡筒的卡置槽172的底壁向靠近上卡筒的方向凸出有若干弧形挡片172a，若干弧形挡片172a的弧形中心及弧形半径均相同，若干弧形挡片172a以上卡筒的筒体160b的中心轴线呈圆周间隔分布，若干弧形挡片172a与卡置槽172的底壁共同围成安放位，以用于安放或者放置或者容纳安装杆的端部。卡置槽172的底壁于安放位的位置还开设有安放槽1721，如此，可以容纳长度更长的安装杆。一实施例中，请参阅图16，下卡筒170的外侧壁凸设有若干加强筋170a，下卡筒的若干加强筋170以上卡筒的筒体的中心轴线为中心呈圆周间隔分布。如此，若干加强筋能够对下卡筒的结构起到较好的加固作用。一实施例中，请结合图16、图18及图19，下卡筒170邻近上卡筒160的端部沿下卡筒170的外侧方向延伸有延伸部170b，又如，延伸部170b自远离下卡筒170的侧壁的方向逐渐向下倾斜。又如，延伸部170b远离下卡筒170的侧壁的端部向下凸设有挡物部170b1。请结合图8及图5，大桶波轮120的定位柱121远离大桶波轮120的一面上开设有环形槽1213，环形槽1213围绕大桶波轮安装孔1212开设。挡物部170b1部分伸入至环形槽1213内，如此，环形槽和挡物部170b1的设置还可以在一定程度上防止异物掉落至大桶波轮安装孔中。

为了使得第三动力输出轴与下卡筒的连接更为牢固，以提高力矩传送效率，一实施例中，请参阅图17至图19，下卡筒170于其下容置孔1724的侧壁上开设有若干嵌设槽1724a，若干嵌设槽1724a以上卡筒160的筒体160b的中心轴线为中心呈圆周间隔分布，也可理解为，若干嵌设槽以第三动力轴的旋转轴线为中心呈圆周间隔分布，动力输出轴连接组件还包括安装嵌件175，安装嵌件175的外侧壁开设有若干嵌设柱1751，安装嵌件175嵌置于下容置孔1724内，且各嵌设柱1751一一对应嵌置于各嵌设槽1724a内，如此，通过设置安装嵌件175，其能够进一步提高下卡筒170与第三动力输出轴153的连接牢固性。具体应用中，安装嵌件175可为金属材质，下卡筒可为塑料材质，将安装嵌件嵌入下卡筒的注塑模具即可制成安装嵌件于下卡筒的连接结构。此外，嵌设柱1751与嵌设槽1724a的配合，能够进一步提高下卡筒与动力轴的力矩传送效率。又如，安装嵌件175的外侧壁凸设有嵌入部1754，下卡筒于下容置孔1724的侧壁凹设有嵌入槽1724，安装嵌件175的嵌入部1754嵌置于嵌入槽1724内。优选的，嵌入部具有多边形形状，嵌入槽具有与嵌入部相对应的形状。如此，能够使得下卡筒与安装嵌件的连接强度较高，且安装嵌件能够较好地第三动力输出轴的力矩传递给下卡筒。请主参阅图19并结合图18，安装嵌件175沿上卡筒160的筒体160b的中心轴线方向开设有顺序连通的动力轴安装孔1753及螺丝穿设孔1752，且螺丝穿设孔1752最靠近下安装孔1723，动力轴安装孔1753的直径大于螺丝穿设孔1752的直径。动力轴安装孔用于安装并容置第三动力轴153的端部。请结合图5，下螺丝320的杆部依次穿过下安装孔1723、螺丝穿设孔1752并螺接三动力输出轴153的螺孔153a，以将下卡筒、安装嵌件与第三动力输出轴153相固定。一实施例中，请结合图4及图19，第三动力输出轴153的端部的外侧壁开设有若干卡位槽1531，请再次参阅图19，安装嵌件175于动力轴安装孔1753的内侧壁凸设有与卡位槽1531一一对应的若干卡位柱(图未示)，卡位柱插入于卡位槽内。如此，卡位柱和卡位槽的配合具有较好的限位作用，能够进一步提高第三动力输出轴与安装嵌件的紧固强度，从而能够提高其力矩传送效率。
为了较好地将小桶波轮安装在小桶内，请再次参阅图5并结合图3，小桶波轮140转动设置于小桶130的安装柱131上。小桶130的底壁开设有小桶安装孔1312，小桶安装孔1312贯穿安装柱131的顶部。请结合图5及图15，洗衣机还包括花键221及轴承222，轴承222支承在小桶安装孔1312内，花键221固定在轴承222的内圈内，使得花键相对小桶安装孔可转动。花键221连接小桶波轮140。例如，花键与小桶波轮的安装可以参照前文内容。如此，通过花键和轴承，能够使得小桶波轮转动设置在安装柱131上。还能够使得小桶波轮通过花键与上卡筒连接，进而使得第三动力输出轴153通过上卡筒及下卡筒带动小桶波轮转动。能够理解，由于小桶的底壁开设有孔，即小桶安装孔，同时，受限于小桶可拆卸的特点，小桶底壁开孔不溢水是一个需要亟待解决的问题，为了使小桶安装孔不出现溢水，一实施例中，轴承为封水轴承或者密封轴承。如此，能够提到较好的水封作用，使得小桶安装孔不出现溢水。一实施例中，请参阅图15、图17至图19，封水轴承222具有内圈2221及外圈2222，封水轴承的内圈2221固定套置在花键221外，请结合图20，封水轴承的外圈2222固定于小桶安装孔1312的内侧壁上。如此，安装较为牢固。一具体实施例中，封水轴承222包括内圈2221、外圈2222及密封圈2223，封水轴承的内圈2221固定套置在花键221外，封水轴承的外圈2222固定于小桶安装孔1312的内侧壁内，封水轴承的内圈2221内圈转动支承在外圈内，例如，通过滚珠，又如，内圈活动套置在外圈内。请参阅图18及图19，外圈2222的外侧壁延伸有安放部2222a，安放部即用于放置密封圈，安放部上开设有安放槽2222b，安放槽用于安放或者放置密封圈。密封圈具有圆环结构，密封圈部分嵌入安放槽内，且密封圈2223与安放槽2222b的侧壁和底壁抵接， 密封圈2223远离安放槽2222b的侧面与定位槽131的底壁抵接。如此，密封圈能够起到较好的水封作用。一实施例中，外圈2222的安放部2222a向外侧还延伸有延伸部2222c，延伸部2222c具有圆环片状结构，延伸部2222c上间隔设置有若干延伸部螺孔，定位槽的底壁设置有若干定位螺孔，各定位螺孔的位置与各延伸部螺孔的位置一一对应，各定位螺孔和各延伸部螺孔分别通过一螺丝相固定。如此，能够较好地外圈固定安装在小桶安装孔1312内。一实施例中，花键221的中部凸设有限位部221a，外圈2222的内侧壁凸设有限位凸起2222d，限位凸起2222d将外圈的空腔分隔为上安放腔2222e及下安放腔2222f，限位凸起围成中安放腔2222g，内圈2221的数量设置为两个，分别为上内圈和下内圈，上内圈及下内圈均套置于花键221外，上内圈支承在上安放腔内，下内圈支承在下安放腔内，花键的限位部221a容置于上安放腔内，限位部整体呈圆环片状结构，限位部的直径大于中安放腔2222g的直径，且花键的限位部221a位于限位凸起2222d和上内圈之间。如此，能够较好地将花键限位，避免其从内圈中掉落。一实施例中，封水轴承还包括容置限位环，容置限位环套置于花键外，且容置限位环位于上内圈和下内圈之间，容置限位环包括相连接的容置环部及限位环部，容置环部的外侧直径分别大于限位环部外侧的直径和中安放腔的直径，限位环部容置在上安放腔内，容置环部容置在中安放腔内，且花键的限位部位于限位环部和限位凸起之间。如此，通过设置容置限位环，能够进一步对花键起到较好的限位作用，避免其从内圈中掉落。此外，本实施例提供的花键，通过设置两个内圈，其灵活性较好，能够较好地提高力矩传送效率，还能够提高封水轴承的整体使用寿命。
需要说明的是，小桶的体积和面积相对均较小，因此引入的小桶波轮面积和直径也相对较小。如何在体积较小的小桶中引入小桶波轮后，来进一步提高水流扰动能力，是一个亟待解决的问题。为了提高小桶波轮的水流扰动能力，请参阅图20和21，本申请还提供一种小桶波轮140波轮包括小桶波轮本体140a，小桶波轮本体140a于一侧的中部凸出形成凸起部142，或者说，小桶波轮本体其朝向小桶开口的一面的中部凸出形成凸起部。凸起部142在小桶波轮本体140a的另一侧形成空腔143，小桶波轮本体140a于空腔的一侧的中部具有连接柱144，连接柱144用于安装花键221。小桶波轮本体140a的中部开设有固定孔141，固定孔141与空腔143贯通，固定孔141贯穿连接柱144，又如，固定孔为螺孔。连接柱用于连接安装连接驱动装置的动力传送机构，连接柱能够开设更大深度的固定孔，进而能够开设长度更长的螺纹。相对于厚度较小的小桶波轮本体，通过连接柱安装连接驱动装置的动力传送机构，由于具有较长的螺纹，因而能够使得小桶波轮与动力传送机构的安装结构强度较好，也能够在一定程度上减少的小桶波轮的损耗。例如，所述连接柱的高度为20毫米至30毫米。优选的，所述连接柱的高度为23毫米至26毫米。如此，能够较好地保证其固定孔中的螺纹长度适宜。请参阅图20和21，凸起部142上凸设有若干小桶波轮凸筋1421，各小桶波轮凸筋1421分别由小桶波轮本体140a的周缘向小桶波轮本体140的转动轴线呈漩涡状延伸。如此，能够使小桶波轮140面向小桶130的开口方向的一侧具有更大的表面积，能够设置长度更长的小桶波轮凸筋，能够进一步提高小桶波轮140的水流扰动能力，从而能够进一步提高对小桶内的衣物的清洗效果。又如，安装柱132至少部分位于空腔143内。又如，凸起部142上凸设有若干小桶波轮凸筋1421，小桶波轮凸筋1421由小桶波轮140的周缘向小桶波轮140的转动轴线呈漩涡状延伸。如此，相对于传统较平的波轮，上述小桶波轮的凸起上能够设置长度更长的凸筋，从而能够提高清洗过程中的水流扰动能力。又如，各小桶波轮凸筋以小桶波轮本体的转动轴线为中心呈环形阵列分布。例如，小桶波轮凸筋的数量为3个至8个。又如，空腔的高度和小桶波轮本体的最大直径的比为0.2：1至0.7：1。例如，小桶波轮的高度为90毫米至110毫米。如此，能够进一步提高水流扰动能力，进而提高了小桶内的清洗效果。需要说明的是，空腔的最大直径，即为空腔沿小桶高度方向的截面的最大直径，或者说，小桶波轮本体边沿小桶高度方向的最大圆截面的直径。例如，空腔的高度与空腔的最大圆形截面的直径的比 值为1/3。如此，能够较好的使空腔容置安装柱，且能够设置长度较为适宜的小桶波轮凸筋。一实施例中，小桶波轮凸筋1421沿小桶波轮本体140a的圆周方向具有相背的正拨水侧面1421a及反拨水侧面1421b，正拨水侧面1421a位于小桶波轮在正转转动过程中切向离心力指向的那一侧，反拨水侧面1421b位于小桶波轮在反转转动过程中切向离心力指向的那一侧，正拨水侧面1421a沿小桶波轮凸筋的延伸方向具有相对的两端，正拨水侧面1421a由两端向其中部逐渐沿靠近反拨水侧面1421b的方向凹陷；反拨水侧面1421b沿小桶波轮凸筋的延伸方向具有相对的两端，反拨水侧面1421b由两端向其中部逐渐沿远离正拨水侧面1421a的方向凸出。如此，正拨水侧面1421a及反拨水侧面1421b的设置具有较好的水流扰动效果，能够进一步提高小桶内的衣物的清洗效果。为了提高小桶波轮的结构强度，例如，空腔143的内表面上环绕小桶波轮140的转动轴线伸出有环形加强筋1431；又如，空腔143的内表面上沿着径向方向伸出有径向加强筋1432。又如，设置多个径向加强筋1432。如此，通过设置多个环形加强筋1431和径向加强筋1432，能够对小桶波轮起到较好的加固作用，降低小桶波轮使用过程中的损坏率。又如，设置多个环形加强筋1431，且多个环形加强筋1431以小桶波轮140的转动轴线呈径向间隔分布。如此，呈径向间隔分布的多个环形加强筋1431能够进一步地对小桶波轮起到较好的加固作用，降低小桶波轮使用过程中的损坏率。又如，安装柱的直径为小桶最小直径的1/3。例如，安装柱的高度为80毫米至110毫米。如此，能够较好地安装小桶波轮。例如，小桶波轮的高度为小桶最小直径的1/4～3/5，优选为小桶最小直径的2/5。如此，能够较好地提高小桶内的衣物清洗效果。
当需要采用本申请的带有小桶波轮的洗衣机进行清洗衣服时：例如，当需要使用大桶110清洗其内的衣物时，则从大桶波轮上拆卸掉小桶及小桶波轮之后，按正常普通波轮洗衣机的清洗即可。具体的，可控制第一动力输出轴151和第二动力输出轴152转动，来带动大桶110和大桶波轮120分别转动，且控制大桶110和大桶波轮120的转动方向相反，如此，完成对大桶110内衣物的清洗；当需要对大桶110内的衣服进行脱水时，则通过控制第一动力输出轴151和第二动力输出轴152转动，使大桶110和大桶波轮120的转动方向相同，通过离心力的作用甩干大桶内的衣物，来完成对大桶110内的衣服的脱水操作。需要说明的是，大桶可以参照现有技术的大桶实现。需要说明的是，如何进行控制大桶或者大桶波轮的转动方向进行洗涤和脱水，还可以参考现有技术实现。例如，当需要使用小桶130清洗其内的衣物时，将小桶安装在大桶波轮上后，则控制第二动力输出轴152和第三动力输出轴153转动，第二动力输出轴152通过大桶波轮120带动小桶130转动，第三动力输出轴153带动小桶波轮140转动，使小桶波轮140的转动方向和小桶130的转动方向相反，以此来实现对小桶内的水流进行较强搅动的效果，来完成对小桶内衣物进行清洗操作。当需要对小桶130内的衣服进行脱水时，则通过控制第二动力输出轴152和第三动力输出轴153转动，使小桶130和小桶波轮140的转动方向相同，通过离心力的作用甩干小桶内的衣物，来完成对小桶130内的衣服的脱水操作。当然，具体的控制方法不限于此，也可以为本领域公知的其它清洗方法，只需要将小桶和小桶波轮当成一个整体当成普通波轮洗衣机来控制其进行清洗。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
