具体实施方式
下面结合附图对本发明的一种洗衣机减速离合装置及洗衣机进行详细描述：
实施例一
参见图1-图4所示，本实施例公开一种洗衣机减速离合装置，包括：
输入轴1；
制动轮，内部具有敞口的内部腔室；
制动轮轴2，套设在输入轴1外部且一端封盖固定在制动轮的敞口端；
轮系，设置在制动轮的内部腔室内；
离合机构，用于仅锁定制动轮轴2，使得输入轴1单独转动，或者释放所述制动轮轴2，并将制动轮轴2与输入轴1连接，使得输入轴1、制动轮17同步转动。
本实施例中，离合机构锁定制动轮轴2，使得制动轮17不会随着输入轴1转动，此时洗衣机执行普通洗涤过程。而需要脱水时，离合机构释放所述制动轮轴2，并将制动轮轴2与输入轴1连接，使得输入轴1转动带动制动轮轴2和制动轮一体转动。
所述离合机构包括传矩轴套33、联接盘3和定位盘4，所述传矩轴套33套装在输入轴1上且与其一体转动，所述定位盘4套设在所述制动轮轴2外部且位置固定，所述联接盘3套装在制动轮轴2上，位于所述传矩轴套33和定位盘4之间且仅可沿轴向滑动，当所述联接盘3向定位盘4滑动与定位盘4连接时，定位盘4通过联接盘3锁定制动轮轴2，使得输入轴1单独转动，当联接盘3向传矩轴套33滑动与传矩轴套33连接时，传矩轴套33通过联接盘3与制动轮轴2联动，使得输入轴1和制动轮轴2同步转动。其中，所述联接盘3包括有连接孔，所述连接孔内壁上设置有内花键，所述制动轮轴2上设置有外花键，所述联接盘3与所述制动轮轴2花键连接，当所述联接盘3向定位盘4滑动与定位盘4连接时，定位盘4在圆周方向上限制联接盘3转动，从而锁定所述制动轮轴2；当定位盘4向传矩轴套33滑动与传矩轴套33连接时，传矩轴套33与联接盘3在圆周方向上联动，传矩轴套33通过联接盘3带动制动轮轴2转动。
制动轮轴2与联接盘3通过花键连接，则制动轮与连接盘在圆周方向一体转动，而联接盘3可沿着制动轮轴2的轴向滑动，当联接盘3向一侧滑动与定位盘4连接时，则定位盘4和联接盘3在圆周方向上为一体，定位盘4位置固定，则联接盘3在圆周方向上被锁定位置，因此制动轮轴2也同样被锁定不可转动，此时输入轴1转动时，制动轮轴2、制动轮并不会跟随转动，而是保持位置固定；当联接盘3向另一侧滑动与传矩轴套33连接时，传矩轴套33与联接盘3在圆周方向上联动，则输入轴1转动时，传矩轴套33一体转动，进而联接盘3、制动轮轴2、制动轮也一体转动。
所述联接盘3的两端分别具有与传矩轴套33和定位盘4啮合的啮合齿，当联接盘3向定位盘4滑动时，联接盘3与定位盘4啮合，定位盘4在圆周方向上限制联接盘3转动，当联接盘3向传矩轴套33滑动与传矩轴套33啮合时，传矩轴套33、联接盘3和制动轮轴2在转动方向上联动。该方案中通过啮合齿实现状态的切换，切换过程快，且稳定性高。
所述联接盘3包括上部环形体和与上部环形体底部连接且同轴设置的下部环形体，上部环形体直径大于下部环形体直径，上部环形体远离下部环形体的一端设置有一周啮合齿用于与所述定位盘4啮合，所述下部环形体的远离上部环形体的一端设置有一周啮合齿，用于与传矩轴套33上的啮合齿啮合。联接盘3是套在制动轮轴2外部，而传矩轴套33是套装在输入轴1上的，因此联接盘3的尺寸大于传矩轴套33，则联接盘3两端的啮合齿需要分别针对需要啮合的部件设置，因此本发明将联接盘3设置为上部环形体和下部环形体，上部环形体直径大，因此设置用于与定位盘4配合的啮合齿，下部环形体直径小，因此设置用于与传矩轴套33啮合的啮合齿，通过该结构设计，使得离合机构切换状态的过程更加稳定。
优选的，减速离合装置包括固定设置在洗衣机的洗涤桶上的外部壳体，所述制动轮安装在所述外部壳体内，所述定位盘4固定安装在所述外部壳体上。外部壳体直接与洗衣机洗涤桶的外桶固定，因此外部壳体和洗衣机的外桶一体固定，定位盘4安装在该外部壳体上，因此位置固定。
所述外部壳体包括上端壳20和下端壳26，所述上端壳固定在所述洗涤桶上，所述下端壳安装在所述上端壳上与上端壳之间形成容纳制动轮的腔室，所述下端壳底部开设有安装孔，所述定位盘4包括圆形透槽，所述定位盘4覆盖安装在所述下端壳的底部，且圆形透槽与所述安装孔同轴，所述制动轮轴2由所述腔室内部向外依次穿过所述安装孔和圆形透槽。定位盘4覆盖安装在下端壳底部，利于与联接盘3配合，锁定所述联接盘3。
所述下端壳底部凸出设置有轴承座262，所述制动轮贯穿所述轴承座262设置，所述定位盘4套装在所述轴承座外部，且定位盘4的圆形透槽与所述轴承座同轴，所述圆形透槽一周设置有啮合齿，所述联接盘3向所述轴承座方向滑动时，联接盘3顶部的啮合齿与所述圆形透槽一周的啮合齿啮合。
所述下端壳26包括圆桶状的侧周壁261，侧周壁的一端为敞口端，另一端向中心收 拢形成环形底壁，所述轴承座261包括由所述环形底壁内边沿向外凸出设置的轴套部，轴套部的外边沿设有向中心弯折的弯折边，该弯折边用于限制轴承安装位置，所述定位盘4包括环形体，环形体的内边沿向一侧凸出形成套筒部，套筒部末端向中心弯折形成有圆环边，所述圆环边上设置有一周齿轮；所述环形体与所述环形底壁贴合连接，所述套筒部套装在所述轴套部上，所述圆环边覆盖在所述弯折边上。
在上述方案中，定位盘4的环形体一周通过紧固件固定在下端壳26的环形底壁上，从而使得定位盘4与下端壳结构一体。
实施例二
参见图1-图5所述，在实施例一的基础上，本实施例二进一步提供洗衣机减速离合装置，该实施例二对离合机构进行进一步详细说明。
具体的，离合机构包括：包括联接盘3和牵引部件，联接盘3具有锁定制动轮轴2，使得输入轴1可单独转动的第一位置和释放制动轮并将制动轮与输入轴1连接使得两者联动的第二位置，所述牵引部件驱动所述联接盘3在所述第一位置和第二位置之间运动。
在上述方案中，离合机构的牵引部件通过驱动所述联接盘3运动即可实现切换输入轴1单独转动和输入轴1和制动轮同步转动，该实施方案结构简单，设计合理，机械性能稳定。
所述离合机构包括拨叉28，拨叉28一端延伸至所述牵引部件，另一端延伸至所述的联接盘3，所述牵引部件驱动所述拨叉28的一端上下拨动，拨叉28的另一端拨动所述联接盘3在所述第一位置和第二位置之间运动。
优选的，所述拨叉28中部可转动的安装在一拨叉支架41上，所述牵引部件包括牵引电机24，牵引电机24的输出轴连接有牵引绳25。所述牵引绳25与拨叉28的一端连接，所述牵引电机24驱动牵引绳25收/放，牵引所述拨叉28相应的一端上下运动，使得拨叉28另一端拨动所述联接盘3在所述第一位置和第二位置之间运动。该方案中，在通过牵引绳25的收/放即可实现驱动联接盘3运动，该驱动方案结构简单精巧，且能耗小。
所述拨叉28的一端设有安装结构282，所述的牵引绳25与所述的安装结构282连接。所述的安装结构282为设置在所述的拨叉28一端的凹陷的环形槽(如图4)，所述的牵引绳25环绕紧固在所述的环形槽内。当牵引电机24收/放牵引绳25时，拨叉28相应的端部上下运动，使得拨叉28另一端拨动所述联接盘3在所述第一位置和第二位 置之间运动。
或者，所述的安装结构282为设置在拨叉28一端的安装孔(未示出)，所述的牵引绳25穿过所述的安装孔，与所述的拨叉25紧固连接。
在另外的方案中，为了便于牵引绳25与拨叉28之间的牵引动作，拨叉28的一端可设置凸柱，凸柱的向牵引电机24所在平面延伸，牵引绳25与凸柱连接。
具体的，当所述的牵引电机24收紧牵引绳25时，拨叉28的一端向下转动(如图3所示)，拨叉28的另一端向上拨动联接盘3，使得联接盘3与定位盘4啮合，此时洗衣机可执行洗涤过程。当需要执行脱水过程/轻揉洗时，则牵引电机24放松牵引绳25，则与牵引绳25配合的拨叉28的一端向上回复，拨叉28的另一端则拨动联接盘3向下运动与传矩轴套33啮合，此时输入轴1带动制动轮一体转动进行脱水或轻揉洗。需要说明的是，洗衣机包括驱动电机32，驱动电机32输出端与所述输入轴1连接，洗衣机通过控制驱动电机32的转动执行所述脱水过程或轻揉洗，两者的区别主要是转速和转动方向的区别。
洗衣机减速离合装置包括安装在洗衣机的洗涤桶上的减速器大板(参见实施例一中的上端盖20)，所述减速器大板包括相邻设置的第一安装部和第二安装部，所述制动轮安装在所述第一安装部上，所述牵引部件安装在所述第二安装部上，所述拨叉28的一端延伸至所述第二安装部上，与所述牵引部件的驱动端接触。
所述离合机构包括传矩轴套33和定位盘4，所述传矩轴套33套装在输入轴1上且与其一体转动，所述定位盘4套装在所述制动轮轴2外部且位置固定，所述联接盘3套装在制动轮轴2上，位于所述传矩轴套33和定位盘4之间且仅可沿轴向滑动，所述定位盘4上凸出设置有拨叉支架41，拨叉28中部可转动的安装在该拨叉支架41上，拨叉28的一端延伸至所述牵引部件，另一端延伸至所述的联接盘3。
优选的，所述联接盘3上设置有环形凸台，所述拨叉28延伸至所述联接盘3的一端设置有半环形夹持部，拨叉28通过所述半环形夹持部281夹持在所述环形凸台上。
在上述方案中，拨叉28的夹持部281夹持在所述联接盘3的环形凸台上，且所述的拨叉28的半环形夹持部281的内径大于所述传矩轴套33的外径，且小于所述的联接盘3上环形凸台的直径。方便带动所述联接盘3上下运动。
再者，本实施例中，拨叉28的一端需要与牵引绳25保持连接状态，实现原理可以是拨叉28连接复位弹簧实现，也可以通过联接盘3的推动实现。具体的，所述联接盘3 与定位盘4/下端盖之间压缩配置有弹簧30，或者在定位盘或者下端盖上安装有弹簧压盖29，弹簧30的顶端抵接在所述弹簧压盖上，弹簧的底端与所述联接盘3接触，向下推动联接盘3。联接盘3在弹簧30的作用下具有向下运动的趋势，而拨叉28的一端抵接在推动部上，另一端作用于该联接盘3，在正常状态下，拨叉28与联接盘配合的一端在弹簧30的作用下，向下运动与传矩轴套33啮合，而拨叉的另一端则向上运动抵接在推顶部的凸条上的最底端，此时洗衣机的输入轴1只能单独转动，洗衣机执行洗涤过程。
而当牵引电机24收紧牵引绳25后，则拨叉28的端部在牵引绳25的拉动下向下运动，则拨叉28的另一端推动拨动联接盘3向上运动，联接盘3在推动部的作用下，压缩弹簧30向上运动与定位盘4啮合，此时输入轴1和制动轮17联动，洗衣机此时可执行脱水或轻揉洗过程。

实施例六
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。
实施例五
参见图1-图5所示，本实施例五中提供一种具有上述实施例一、实施例二和实施例 三中的减速离合装置的洗衣机，该洗衣机具有实施例三中两种洗涤状态，即第一运行状态和第二运行状态，同时该洗衣机还具有脱水状态。
该洗衣机包括驱动电机32，驱动电机32与所述输入轴1连接，在洗涤过程需要进入第一运行状态时，洗衣机控制牵引部件驱动联接盘向上运动与定位盘啮合，定位盘通过联接盘锁定制动轮轴，如此则驱动电机驱动输入轴转动，输入轴1将动力传输至第一定轴轮系，第一定轴轮系将动力输出至输出轴22，输出轴22同时将动力传输至第二定轴轮系，第二定轴轮系将动力输出至输出轴套21，输出轴与输出轴套21反向转动。当需要进入脱水阶段或需要进入第二运行状态时，洗衣机控制牵引部件驱动联接盘向下运动与输入轴上的传矩轴套33啮合，则电机驱动输入轴1转动，输入轴1与制动轮轴2同步转动，输入轴1与制动轮轴2带动制动轮17以及内部的第一定轴轮系和第二定轴轮系同步转动，输出轴21与输出轴套21同速同向转动。
其中，需要说明的是，脱水状态和所述第二运行状态的不同主要在于转速不同，在要进入脱水状态时，洗衣机控制电机高速旋转，而在要进入第二运行状态时，洗衣机控制电机低速转动，再者，另一不同之处在于，脱水状态中，洗衣机控制电机向一个方向转动，实现脱水，而在第二运行状态中，洗衣机控制电机间隔循环的执行正反转过程，实现对衣物的轻揉洗，达到良好的清洗效果。
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。
