这样，本实施例的洗衣机减速离合装置应用在洗衣机上后，可以实现洗衣机在洗涤/漂洗过程中输出轴22及输出轴套21两个动力输出，当输出轴22和输出轴套21的两个转向相对相反时，分别带动内桶和波轮相对反向运动，实现双动力洗涤效果，增加洗涤水流的多样性，提高洗涤效果；当输出轴22和输出轴套21同速同向转动时，分别带动内桶和波轮同速同向转动，实现对衣物较小摩擦的轻柔洗效果。
具体地，本实施例所述的第一定轴轮系包括第一定轴齿轮组，所述的第一内齿圈9与第一定轴齿轮组内啮合传动。本实施例的第一定轴轮系采用第一定轴齿轮组与第一内齿圈9啮合传动的方式实现减速的作用，整体结构更加简单，易于装配，通过第一内齿圈9将动力传递至输出轴22，扭矩的传递更加稳定。
进一步地，本实施例所述的第一定轴齿轮组包括一级定轴齿轮组和二级定轴齿轮组，所述的一级定轴齿轮组8-1与二级定轴齿轮组8-2外啮合传动，所述的二级定轴齿 轮组8-2与内齿圈9内啮合传动。本实施例的第一定轴齿轮组8-1采用两级定轴齿轮外啮合传动，不仅实现了减速，而且兼具换向功能。

本实施例创造性的采用输出轴22一方面作为洗衣机波轮的动力输出，另一方面作 为第二定轴轮系的动力输入；另外，通过第二内齿圈13的引入实现了动力传递的换向，使得输出轴套21与输出轴22具有相反的转动反向，即输出轴套21连接的洗衣机的洗涤桶与输出轴22连接的洗衣机的波轮具有相反的转向，以实现洗衣机洗涤/漂洗过程中的双向水流，提升洗涤效果。
为了实现第二定轴齿轮组与输出轴22之间的传动，所述的第二定轴轮系包括固定安装在输出轴21上的中心齿轮14，所述的第二定轴轮架12包括多个第二齿轮轴31，第二定轴齿轮组包括分别可转动的安装在各第二齿轮轴31上的第二定轴齿轮，所述的中心齿轮14与所有第二定轴齿轮外啮合传动，所有所述第二定轴齿轮与第二内齿圈13内啮合传动。

实施例二
本实施例提供一种洗衣机的控制方法，具体包括：洗衣机的洗涤过程中包括内桶和波轮在旋转时处于相对静止的状态。
本实施例中的洗衣机为带有波轮的洗衣机，内桶为洗涤桶，内桶可以为有孔内桶也可以为无孔内桶。波轮设置在内桶的底部。一般的洗衣机在洗涤过程中，波轮旋转带动水流运转，对衣物进行冲刷清洗，对于双动力的洗衣机，内桶和波轮可以同时在洗涤过程中旋转，产生的水流比仅波轮旋转时更加强有力，但也仅包括较为单一的洗涤水流， 洗涤效果有限，提高并不显著。
本实施例在洗涤过程中可以实现内桶和波轮在旋转时处于相对静止的状态，从而增加内桶和波轮同向同速转动下的水流形式，增加了洗涤水流的多样性，实现轻柔洗涤，提高对衣物的洗护效果。
具体的，洗衣机的洗涤过程中包括第一运行状态和/或第二运行状态；在第一运行状态下，内桶和波轮在旋转时处于相对运动状态，在第二运行状态下，内桶和波轮在旋转时处于相对静止状态。
在第一运行状态下，内桶和波轮处于相对运动状态包括：内桶和波轮进行反向旋转，转速相同或者不同。第二运行状态下，内桶和波轮处于相对静止状态包括：内桶和波轮同向且同速转动；具体的，内桶和波轮以相同的转速同时沿顺时针方向或者逆时针方向旋转。
在同一洗涤过程中，洗衣机既可以一直保持内桶和波轮在旋转时处于相对静止的状态；也可以一直保持相对运动状态；也可以仅部分时间执行相对静止状态，部分时间相对运动，不同状态之间可以进行切换，实现多种水流，进一步增加洗涤效果。
作为本实施例的一种实施方式，本实施例提供一种洗衣机的控制方法，具体包括：
同一洗涤过程中，洗衣机仅执行第一运行状态，或者，仅执行第二运行状态。
本实施例中，同一洗涤过程中，内桶和波轮可以仅执行第一运行状态，内桶和波轮相对运动，进行同向不同速或者反向旋转运动，可以形成较强劲的水流，有利于提高洗涤效果。
另外，同一洗涤过程中，内桶和波轮也可以仅执行第二运行状态时，内桶和波轮一直保持相对静止的状态，也就是说内桶和波轮在洗涤过程中同速同向旋转，形成新形式的水流，有利于对轻柔质地的衣物进行轻柔洗涤。
内桶和波轮在洗涤过程中同速同向旋转的情况包括：
情况1：内桶和波轮在洗涤过程中一直按照顺时针方向同向同速旋转；
情况2：内桶和波轮在洗涤过程中一直按照逆时针方向同向同速旋转；
情况3：内桶和波轮在洗涤过程中在同速同向顺时针旋转和同速同向逆时针旋转之间切换执行。
不论哪种情况，在同一洗涤过程中，内桶和波轮一直处于保持相对静止的状态，实现了内桶和波轮同向同速转动下的水流形式，能够更加轻柔洗涤，提高对轻柔质地衣物 的洗护效果。
作为本实施例的一种实施方式，本实施例提供一种洗衣机的控制方法，具体包括：
洗衣机的洗涤过程包括第一运行状态和第二运行状态，且第一运行状态和第二运行状态之间可进行切换；
其中，在第一运行状态下，内桶和波轮在旋转时处于相对运动状态，在第二运行状态下，内桶和波轮在旋转时处于相对静止状态。
本方案中，在洗涤过程中可以在两种运行状态之间进行切换，两种运行状态下可以产生不同的洗涤水流，如此增加洗涤水流的多样性，可以能够提高对衣物的洗涤效率和洗净比。
具体的，洗涤过程中的两种运行状态包括内桶与波轮相对静止的状态和内桶与波轮相对运动的状态；当内桶与波轮在旋转过程中处于相对静止状态下时，形成的水流方向一致，流速稳定，如此衣物受到的拉扯力或者牵伸力小，能够降低对衣物的磨损，实现轻柔洗涤；而内桶与波轮相对运动的状态下，形成的水流强度较大，如此，这两种状态进行切换洗涤，相互配合，既能够提高洗涤效果，还能够达到保护衣物，降低衣物磨损形变的作用，满足用户的需求。
洗涤过程中，在第二运行状态下，内桶和波轮处于相对静止状态包括：内桶和波轮同向且同速转动。其中，内桶和波轮可以同时以相同的转速沿顺时针方向旋转，也可以沿着逆时针方向旋转。如此，尽管内桶和波轮都在旋转，但两者的运动完全同步，两者相对静止，内桶中形成的水流则以同样的稳定的速度朝着同一方向流动，内桶中的衣物随着如此的水流运动，受到的拉扯力最小，对于丝质、毛质等容易形变的衣物来说，此种轻柔洗涤过程更加适宜。
而在第一运行状态下，内桶和波轮处于相对运动状态的方式可以包括多种，不同的方式可以形成较为不同的强度大的水流，本实施例中第一运行状态与第二运行状态形成的水流相互配合进行洗涤，第一运行状态下内桶和波轮的运动方式可以包括以下几种方案：
方案1，内桶和波轮进行反向旋转，同时内桶和波轮的转速相同；
内桶和波轮反向旋转，内桶和波轮的转速相同，形成两股沿相反方向旋转的水流，两股水流的相遇之处形成较强有力的旋转水流，对衣物造成较大的冲刷，保证洗涤效果和洁净率。
方案2，内桶和波轮进行反向旋转，同时内桶和波轮的转速不同，与方案1效果一样，内桶和波轮的旋转能够形成较强有力的旋转水流，对衣物造成较大的冲刷和拉力，保证洗涤效果和洁净率。
作为一种优选的方案，所述的内桶和波轮反向旋转时，转速不同且转速差值为定值或者变值，如此可以预先设置一定强度的水流，该水流的强度适合大多数衣物，既能够保证达到较高的洗涤效率，又能够避免损坏衣物。
方案3，在第一运行状态下，内桶和波轮同向旋转，内桶和波轮的转速不同，内桶和波轮同向但不同速旋转时，也能够形成强度较大的旋转流水，保障洗涤效率。
进一步的，内桶和波轮同向不同速旋转，且内桶和波轮的转速差值为定值或变值；如此可以预先设置一定强度的水流，也有利于形成稳定的洗涤程序。
在第一运行状态下，内桶和波轮反向旋转时的转速差值不大于当内桶和波轮同向不同速旋转时的转速差值。如此能够形成强度较为适宜，较为稳定的水流，提高洗涤效果和洁净率。
另外，本实施例中，当在同一洗涤过程中切换执行第一运行状态和第二运行状态时，具体的方法可以包括但不限于以下几种具体方案：
方案1，在同一洗涤过程中，洗衣机依次执行第一运行状态/第二运行状态和第二运行状态/第一运行状态。
本方案中，洗衣机执行一次第一运行状态，并执行一次第二运行状态，可以先执行第一运行状态再执行第二运行状态，也可以先执行第二运行状态再执行第一运行状态。第一运行状态和第二运行状态的运行时间可以根据需要进行预先设定。例如，用户选择运行洗涤程序后，洗衣机先控制执行第一运行状态达到T1时间，然后再执行第二运行状态达到T2时间，其中T1时间和T2时间可以相同也可以不同，具体可以根据需要预先设定或者由用户自行设定。
方案2，洗衣机控制第一运行状态和第二运行状态之间进行多次切换，交替执行第一运行状态和第二运行状态。
本方案中，洗衣机执行n次第一运行状态和第二运行状态，第一运行状态和第二运行状态交替运行，洗衣机定时或者不定时在两者之间进行切换。如此，洗涤过程中形成的水流更加多样化，两种运行状态相互配合，达到对衣物高洗涤效率和高洁净率的目的，也能够大大降低对衣物的磨损。
进一步的方案，在同一洗涤过程中交替执行第一运行状态和第二运行状态，在每次处于第一运行状态中时，波轮和内桶反向旋转或者波轮和内桶均同向不同速旋转，处于第二运行状态时，内桶和波轮同向同速沿顺时针方向或者逆时针方向旋转。
洗衣机在交替执行多次第一运行状态和第二运行状态时，第一运行状态下，每一次的内桶和波轮的运行状态可以相同，也可以不相同，例如内桶和波轮每一次都反向转动，或者每一次都同向不同速运动，如此运行较为规律，衣物的旋转方向也较为规律，可以减少衣物的缠绕。或者，前一次内桶和波轮反向转动，后一次内桶和波轮同向不同速转动，如此能够形成更加多样化的水流，提高对衣物的清洁率。第二运行状态下，内桶和波轮同向同转速旋转，每一次切换执行第二运行状态时，内桶和波轮可以采用与前一次相同或者不同的转速旋转，可以沿着顺时针方向旋转，也可以沿着逆时针方向旋转。
进一步的方案，在同一洗涤过程中，洗衣机交替执行第一运行状态和第二运行状态，在每次处于第一运行状态中时，波轮和内桶每次均反向旋转，并且波轮和内桶的转速差值为定值。在每次处于第二运行状态中时，波轮和内桶每次均同向同速沿顺时针方向进行旋转。如此内桶和波轮的运行较为规律，衣物的旋转方向也较为规律，可以减少衣物的缠绕。
进一步的方案，第二运行状态下，波轮和内桶同向旋转，且转速均为V1，所述V1不小于第一运行状态下内桶和波轮旋转时转速的较小值。如此，既能够提高对衣物的洗涤效率和洗净比，又能够降低对衣物的磨损，实现轻柔洗涤，满足用户的需求。
作为本实施例的一种实施方式，本实施例提供一种洗衣机的控制方法，本实施例中洗涤过程运行第一状态、或者运行第二运行状态，或者运行第一运行状态和第二运行状态。在第一运行状态下，内桶和波轮在旋转时处于相对运动状态，在第二运行状态下，内桶和波轮在旋转时处于相对静止状态。
本实施例中，既可以在现有的洗衣机的普通洗涤程序的洗涤过程中增加第二运行状态，也可以在现有洗衣机上单独设置轻柔洗涤模式，增加轻柔洗模式，单独执行轻柔洗过程。当用户选择了洗涤过程可切换的普通洗涤程序或者轻柔洗涤模式后，洗衣机在洗涤过程中则切换执行第一运行状态和第二运行状态，或者单独执行第二运行状态。
具体的，本实施例可以在现有的洗衣机程序的基础上，单独设置轻柔洗程序，增加用户可选择的洗涤程序，丰富洗衣机程序，提升用户的体验，具体包括：
为了便于用户选择，已有的洗衣机包括普通洗涤程序，快速洗涤程序等，洗衣机还 包括轻柔洗程序和强力洗程序，在轻柔洗程序的洗涤过程中，洗衣机可以只执行第二运行状态，或者可以切换执行第一运行状态和第二运行状态；在强力洗程序的洗涤过程中，洗衣机执行第一运行状态，运行过程中，内桶和波轮反向旋转，形成较为强有力的水流，提高洗衣效果。
该轻柔洗涤程序为在现有洗衣机的基础上额外增加的程序，针对质地柔软的衣物，当用户选择轻柔洗涤程序并运行后，洗衣机可以单独只执行第二运行状态，内桶和波轮可以同速同向按照顺时针和/或逆时针的方向进行旋转，当用户在下一次选择了强力洗程序时，切换至第一运行状态执行洗涤过程。轻柔洗涤程序也可以在第一运行状态和第二运行状态切换，使较强的水流和较轻柔的水流切换运行，达到丰富洗衣水流，提高洗涤效果，避免衣物形变的目的。
如此，洗衣机的程序中不仅包括普通洗涤程序，还包括强力洗涤程序和轻柔洗涤程序，用户可以根据衣物质地以及脏污程度等自主选择合适的洗涤程序，能够在不同的洗涤程序/运行状态之间进行切换，不仅丰富了洗衣机的洗涤程序，丰富了洗衣水流，提升用户体验，也能够达到提高洗衣和护衣效果的目的。
本实施例的洗衣机包括减速离合装置，所述减速离合装置上设置切换机构，所述切换机构分别与内桶和波轮连接；执行洗涤过程时，洗衣机通过切换机构控制内桶和波轮切换运行第一运行状态和第二运行状态。
本方案中，减速离合装置上设置切换机构，洗衣机的控制装置通过控制切换机构来控制内桶和波轮的旋转状态，在第一运行状态下控制内桶和波轮反向旋转或者同向不同速旋转，在第二运行状态下控制内桶和波轮同向同速旋转。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
