该驱动装置300对搅水结构200的驱动可以通过直接与搅水结构200连接或者间接与搅水结构200连接来实现。驱动装置300能够交替输出两个相反方向的运动，其可以通过单独的动力部件，如电机来实现，也可以通过动力部件加传动机构的方式来实现。
如图2所示，一种实施例中，该搅水结构200形成的两个相反方向的运动均在水平面内进行。该洗衣桶100竖直放置，通常情况下将洗衣桶100的顶部开口作为取放衣物的窗口。当然，某些实施例中，也可考虑从洗衣桶100的侧方开口作为取放衣物的窗口，但搅水结构200的运动是在水平面内进行。
搅水结构200所做的运动可以有多种，例如往复直线运动等。在一 种实施例中，该搅水结构200形成的运动包括往复旋转运动、圆弧轨迹的往复运动、圆形轨迹的往复运动中的至少其一。所说的往复旋转运动是指搅水结构200自身交替正转和反转。所说的圆弧轨迹的往复运动是指搅水结构200单方向的运动轨迹为圆弧形，其在整个过程中沿着圆弧形轨迹往复运动。所说的圆形轨迹的往复运动是指搅水结构200单方向的运动轨迹为圆形轨迹，其在整个过程中沿着圆形轨迹往复运动。除此之外，还可以有其他轨迹的往复运动。
进一步地，为了较好地减少容置腔101内形成漩涡水流的可能，尤其是该驱动装置300输出正转和反转运动，例如采用正反转电机时，可驱动搅水结构200做旋转、圆弧轨迹的往复运动或圆形轨迹的往复运动。一种实施例中，该正转运动和反转运动的转动角度a不超过360°，即使搅水结构200在同一方向上的旋转或运动不超过一圈，从而在水流还未形成漩涡之前就换向运动，从而形成频繁的相向运动，不会使衣物缠绕在一起，因此不伤衣物，而且这种流动能使衣物在水流中舒展开，保证衣物更充分的与水流和洗涤液进行接触，提高清洗效果。同时，水流所形成的频繁相向运动可以增加水流对衣物的有效揉搓效果，进一步提高对衣物的清洗效果。
更好的一种方式是，该正转运动和反转运动的转动角度a取值范围为：90°≤a≤270°，例如取180°。
进一步地，请参考图2和3，一种实施例中，该搅水结构200包括条状的搅水条210、220，该搅水条210、220相互独立地竖直设置在容置腔101内，这样可以使搅水结构200运动时与水液有更多的接触区域，保证搅水条对水流作用力的均匀性，推动各层水流运动，使水流能够迅速响应搅水条210、220的运动，加快水流的变化，提高水流对衣物的清洗效果。该竖直设置不仅包括完全的竖直设置，也包括大致呈竖直排布这种方式。当然，在其他实施例中，也可以将搅水结构200设计为其他形状。
请参考图3，一种实施例中，搅水条210、220具有用于在运动过程中带动水流运动的第一搅水面211、221和第二搅水面212、222，该第一搅水面211、221和第二搅水面212、222均与容置腔101的底壁垂直，且该第一搅水面211、221和第二搅水面212、222相背离的设置在搅水条210、220上。这样，当搅水条210、220正反方向运动时，都有一个 搅水面主要用于推动水流运动，保证搅水效果。
该搅水条210、220的搅水面可以为平面、弧面、折面或者其他组合。该搅水条210、220的横截面可以为方形、圆形或者异形。
为了提高搅水效果，在一些实施例中，该搅水结构200为两个以上，该两个以上的搅水结构200以洗衣桶100中心线为旋转对称中心呈旋转对称设置，从而使容置腔101内水流在间隔均匀的位置形成相向运动，对容置腔101各处的衣物都能够起到较好的清洗效果。
进一步地，该搅水结构200可以设置在不同的位置，例如容置腔101的侧壁和底壁中至少其一设置有搅水结构200。
请参考图1-4，一种实施例中，该洗衣桶100包括储水桶110、滤筒120和转盘130。该储水桶110用于在洗衣过程中存储水，该滤筒120容置在储水桶110内，该滤筒120具有多个滤水孔121，使水能够进出滤筒120。该转盘130与滤筒120围成上述的容置腔101。在水洗过程中，储水桶110主要用于存储水液，而滤筒120和转盘130容置在储水桶110内。
进一步地，请参考图2和3，一种实施例中，该搅水条210安装在滤筒120的内壁并且其至少一部分自滤筒120的内壁向容置腔101内凸起，该驱动装置300驱动滤筒120转动，从而带动搅水条210运动。
该驱动装置300对滤筒120的驱动可以是直接或间接与滤筒120连接，例如，如图3和4所示，在一种实施例中，该滤筒120和转盘130固定连接或成一体结构，该驱动装置300与转盘130连接，从而达到驱动滤筒120和搅水条210运动的目的。
进一步地，请继续参考图2和3，一种实施例中，该搅水条220安装在转盘130上，并且该搅水条220向上伸入到容置腔101内，该驱动装置300驱动转盘130转动，从而带动搅水条220运动。该搅水条220为至少两个，其相互独立地竖直设置在转盘130上，这样可以在不增加转盘130高度的情况下，增加搅水条220对洗衣机内水流的作用面积。
当滤筒120和转盘130一体成型或者固定连接时，驱动装置300可以通过驱动转盘130或滤筒120直接驱动搅水条210和搅水条220一起运动。
为了使搅水条210运动时能够带动足够的水流运动，一些实施例中，该搅水条210的自容置腔101的侧壁向容置腔101内部凸起的高度不低 于2cm，从而使搅水条210伸入水液中的部分足够深，以便能够带动更多水液形成水流，使流动起来的水量更多，从而在搅水条210反向运动时使水流产生更大范围的相向运动，进而提高水流与衣物的揉搓力度，增加清洗效果此外，还可以使搅水条210到接近于顶部，例如距离滤筒120顶部3-4cm，这样可以使搅水条210可以在竖直方向带动足够多的水流一起运动，在反向运动时可以使水流迅速响应搅水条210传递的运动，提高水流与衣物的揉搓力度，增加清洗效果。
同样的，为了使搅水条220运动时能够带动足够的水流运动，一些实施例中，该搅水条220自容置腔101的底壁向上凸起的长度不低于容置腔101深度的五分之一，从而使搅水条220向上伸入水液中的部分足够长，以便能够带动更多水液形成水流，从而在搅水条220反向运动时可以使水流迅速响应搅水条210传递的运动，使水流产生更大范围的相向运动，进而提高水流与衣物的揉搓力度，增加清洗效果。
该滤筒120和转盘130之间可以是分离的，从而驱动装置300可以分别带动滤筒120和转盘130进行旋转或运动。此时，该滤筒120可设置搅水条210，转盘130可设置搅水条220，该搅水条210和搅水条220的运动方向相同或相反，从而起到不同的搅水效果。
此外，请参考图5，一种实施例中，可以只在滤筒120设置搅水条210，该搅水条210安装在滤筒120的内壁并且其至少一部分自滤筒120的内壁向容置腔101内凸起。该驱动装置300驱动滤筒120转动，从而带动搅水条210运动。同样地，当滤筒120和转盘130是分离结构时，该驱动装置300可以直接驱动滤筒120转动，或者当滤筒120和转盘130为一体结构或固定连接时，该驱动装置300可以通过驱动转盘130来带动滤筒120转动。
请参考图6，一种实施例中，还可以只在转盘130设置搅水条220，该搅水条220向上伸入到容置腔101内，该驱动装置300驱动转盘130转动，从而带动搅水条220运动。对此，该驱动装置300可以直接驱动转盘130转动。或者当滤筒120和转盘130为一体结构或固定连接时，该驱动装置300可以通过驱动滤筒120来带动转盘130转动。
另一方面，在某些实施例中，该洗衣桶可以包括桶体和转盘，桶体不开设滤孔，该转盘与桶体围成容置腔。该搅水结构包括搅水条，该搅水条安装在转盘上且能够随转盘移动，该驱动装置驱动转盘转动，从而 带动转盘以及搅水条转动。桶体和转盘可以分离设置，且两者之间形成动密封，使转盘转动时与桶体之间能够保持密封。为了便于桶体排水或进水，桶体上可以设置排水口或进水口。
进一步地，请参考图1和4，一种实施例中，该驱动装置300包括能够正转和反转的电机，该电机的正转和反转形成两个相反方向的运动，从而带动搅水结构200带动水流形成频繁的相向运动。电机可通过联轴器800与转盘130连接。
为了减少电机使用过程中带来的振动和噪音，请继续参考图1，在一种实施例中，该洗衣机还包括支架400和弹性减震机构，该驱动装置300包括能够正转和反转的电机，该电机通过弹性减震机构安装在支架400上。该洗衣桶100也可以支撑在支架400上。请参看图1和2，当洗衣桶100具有储水桶110和滤筒120时，该储水桶110可以固定在支架400上，而滤筒120设置为可以转动的。
请继续参考图1，在一种实施例中，该弹性减震机构包括至少一个减震弹簧600，该驱动装置300包括电机，该电机固定安装在电机座500上，该减震弹簧600设置在电机座500与支架400之间，使电机座500与支架400通过减震弹簧600连接。该减震弹簧600不仅在其伸缩方向上能够吸收振动，而且在垂直于其伸缩方向的方向上也能够吸收振动，从而减少电机上下左右四个方向上振动，进而减少洗衣机的振动所带来的噪音。
进一步地，请参考图1，该电机座500与支架400的至少一部分形成上下结构，该减震弹簧600竖直连接在电机座500与支架400之间，这种设计使得驱动装置300的重量主要作用在减震弹簧600的伸缩方向，从而可以避免减震弹簧600向其他方向变形，延长减震弹簧600使用寿命。
具体来说，请继续参考图1，一种实施例中，该减震弹簧600为三个，该三个减震弹簧600成三角形围绕在电机四周，利用三角形结构对驱动装置300进行更稳固的支撑。
另一方面，请参考图1和4，一种实施例中，该洗衣机还包括排水系统(图中未示出，但并不影响本领域技术人员的理解)和盖体700，该盖体700以可拆卸的方式安装在洗衣桶100上，例如通过可翻转的形式安装在洗衣桶100上。该排水系统具有排水管道和设置于排水管道上 的阀门，该排水管道与洗衣桶100连通，用于将洗衣桶100内的水排出。具体地，该排水管道可以与储水桶110底部的如图4所示的排水口112连通。
在其他实施例中，也可以设置进水系统，向洗衣桶100内供水。当然，也可以通过人工的方式向洗衣桶100内加水。
在其他实施例中，盖体700也可以省略或设计为透明，以便观察到洗衣桶100内的清洗情况。
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
