洗衣机，作为一种家用电器，逐渐成为人们生活中不可或缺的一部分，而全自动波轮洗衣机作为一种主要的洗衣机类型，其应用范围也越来越广泛。现有全自动波轮洗衣机的工作方式一般为，洗涤和漂洗时，驱动装置通过减速离合装置驱动洗衣机的波轮正反转，脱水时，驱动装置通过减速离合装置驱动洗衣机的波轮和洗涤桶同步高速转动。
然而随着科技的高速发展，现有全自动波轮洗衣机单纯依靠波轮搅拌水流的洗涤方式对于衣物洗涤效果的提升越发有限，因此，如何增加全自动波轮洗衣机的洗涤多样性，以提升洗涤效果成为一个急需解决的技术问题。
现已有一些专利针对这一问题提出了解决方案，例如申请号为：02804912.8，名称为一种用于产生双向转动的传动机构、用于产生双向洗涤的洗衣机和方法及相关的内桶和搅拌器的中国发明专利，该专利公开了一种适合于在洗衣机中使用的产生双向驱动的传动机构，其包括一个动力输入端和两个动力输出端，其中一个动力输出端与一个搅拌器轴(10)相连，并使搅拌器轴沿第一方向转动；而其另一动力输出端与一个内桶轴(11)相连，并使内桶轴沿与第一方向相反的第二方向转动。一种用于产生双向洗涤的洗衣机以及一种能够在洗衣机中产生双向洗涤的洗涤方法。一种用于洗衣机的搅拌器和内桶。该专利公开了一种可使洗衣机产生双向驱动的传动机构，同时在说明书中公开了该传动机构的具体结构，由说明书和附图的内容可知，该专利在某种程度上解决了现有全自动波轮洗衣机洗涤时动力驱动方式单一的问题，但是其公开的传动机构结构复杂，制造装配难度高，制造成本高等问题。
再例如申请号为：201310408108.X，名称为：全自动洗衣机的中国发明专利申请，该发明公开了一种全自动洗衣机，包括外桶、内桶、波轮及驱动装置，所述的驱动装置 包括至少两个转子和至少一个定子，其中一转子与内桶轴连接，还有一转子与波轮轴连接；所述的驱动装置为变频直驱电机，所述的转子、定子、内桶轴及波轮轴同轴设置，内桶轴中空，波轮轴设于内桶轴中；所述的洗衣机洗涤时波轮与内桶同向转动，或者互为反向转动，或者波轮、内桶之一转动，脱水时波轮与内桶同向同速转动。该发明所述的洗衣机，其通过两个转子各自与内桶轴和波轮轴连接，通过双转子分别驱动内桶和波轮转动，这种结构在很大程度上降低了驱动系统的重量、体积和成本，提高了传动效率和稳定性。
由上述两篇公开的专利申请文献可知，现有解决洗衣机水流多样性的两种主要构思：方式一、设计一种可输出双向动力的减速离合装置实现洗衣机洗涤过程中的双向洗涤，增强水流效果；方式二、设计一种具有双向动力输出的驱动电机，分别驱动波轮和内桶实现洗衣机洗涤过程中的双向洗涤，增强水流效果。上述方式一存在有减速离合装置结构复杂，安装困难以及控制方法复杂的弊端，方式二存在具有双向动力输出的驱动电机的成本高的弊端。
有鉴于此，如何增加洗涤方式的多样性，并在多种洗涤方式之间进行切换以选择最佳的洗涤方式便成为本申请所要解决的技术问题。
