请结合参阅图7、图8、图9、图12至图16，排水阀组件3包括阀芯31、弹性件33、以及传动杆机构32，排水阀组件3会跟随内筒11转动。
传动杆机构32具有转动中心线，传动杆机构32绕转动中心线自转的同时也会围绕内筒11的转动轴线公转。
阀芯31用于密封排水孔。具体地，阀芯31具有打开排水孔的排水位置(参照图13和图15)和密封排水孔的密封位置(参照图12、图14和图16)，阀芯31能够在密封排水孔的密封位置和打开排水孔的排水位置之间平动，也就是说，阀芯31不会翻转。
该实施例中，阀芯31的运动方式为平动，使得阀芯31用于封闭排水孔的一侧始终朝向排水孔，在阀芯31从排水位置切换至密封位置时，阀芯31用于封闭排水孔的一侧能够平稳地、可靠地直接或间接地压靠在排水孔的周围，能够极大地提升排水孔的密封可靠性，密封效果较好。
在洗涤过程中，或者其他不需要排水的情况下，请参阅图7、图12、图14、图16，阀芯31处于密封位置，阀芯31密封排水孔，内筒11内的水不会排出，内筒11起盛水桶的作用。当需要排水或脱水时，请参阅图13和图15，阀芯31从密封位置切换至排水位置，排水孔敞开，内筒11内的 水经排水孔排出内筒11。
排水孔可以设置于内筒11的合适位置，只要使得内筒11内的水能够通过排水孔排出即可。
示例性地，排水孔形成于内筒11的转动周向，以便于内筒11在脱水过程中通过离心力将水从排水孔中甩出。
需要说明的是，内筒11的转动轴线可以沿水平方向延伸，也可以沿竖直方向延伸，还可以沿介于水平方向和竖直方向之间的倾斜方向延伸，在此不做限制。
本申请一实施例中，请参阅图1和图2，内筒11的转动轴线大致沿水平方向，在内筒11转动过程中，排水孔可以循环经过内筒11的转动轨迹的最低点，可以无死角地将内筒11内的水排空。
示例性的，一实施例中，请参阅图1和图2，洗涤设备包括外桶12，内筒11转动地设置于外桶12内，不仅可以利用外桶12对内筒11起支撑作用，还可以通过外桶12排水，具体地，从排水孔中排出的液体进入外桶12，外桶12集中将液体排出洗涤设备。

传动杆机构32具有转动中心线，传动杆机构32绕该转动中心线自转。请参阅图9、图14和图15，传动杆机构32具有转杆3231，转杆3231与转动中心线偏心设置且绕转动中心线转动。传动杆机构32远离阀芯31的一端用于接收驱动机构2的驱动力。
请参阅图10和图14，阀芯31具有锁口31a，请参阅图15，当转杆3231转动进入锁口31a内，转杆3231迫使阀芯31从密封位置运动至排水位置， 且阀芯31在弹性件33的作用下将转杆3231限制在锁口31a内。具体地，由于转杆3231转入了锁口31a内，转杆3231阻止阀芯31朝向排水孔运动，阀芯31在弹性件33的作用下紧紧钩住转杆3231，使得转杆3231被锁在锁口31a内。因此，如果没有驱动力驱动传动杆机构32转动，则阀芯31会稳定地处于当前位置。
当驱动力作用在传动杆机构32上，驱动传动杆机构32反方向转动，请参阅图14，当转杆3231转动至脱离锁口31a，也就是说，转杆3231不再阻挡阀芯31，弹性件33驱动阀芯31从排水位置运动至密封位置，也就是说，转杆3231只驱动阀芯31从密封位置运动至排水位置，而不会驱动阀芯31从排水位置运动至密封位置。
需要说明的是，控制装置和驱动机构2通讯；控制装置控制驱动机构2驱动传动杆机构32绕转动中心线转动。
本申请实施例的排水阀组件3，无论内筒11的转速如何，只要能够使得传动杆机构32转动即可实现阀芯31在密封位置和排水位置之间切换，结构简单、便于内筒11排水，可靠性较高，能够有效地提升排水阀组件3的使用寿命。此外，弹性件33只需要能够驱动阀芯31直线运动即可，弹性件33可以采用简单的柱形弹簧，例如，压簧。结构简单，可靠性高，便于装配。
需要说明的是，洗涤设备在洗涤过程中或者洗涤结束后通过排水孔排水，洗涤设备在脱水过程中也可以通过排水孔排水。
示例性地，请参阅图14，当转杆3231脱离锁口31a，转杆3231与阀芯31间隔设置，即转杆3231不与阀芯31接触，转杆3231不对阀芯31施加作用力，不会对弹性件33施加阻力，使得弹性件33可以充分利用其弹力将阀芯31驱动至密封位置且保持在密封位置。
示例性地，请参阅图12、图13和图16，弹性件33对阀芯31施加的 作用力始终与阀芯31的运动方向平行，也就是说，弹性件33对阀芯31的作用力始终朝向排水孔。弹性件33对阀芯31施加的作用力方向不会因为阀芯31的位置改变而改变。
示例性地，在转杆3231转动进入锁口31a的过程中，例如，请参阅图15，转杆3231沿图15中的顺时针方向转动，转杆3231能够越过其转动轨迹的最低点。具体地，请参阅图16，当阀芯31处于密封位置时，转杆3231的位置为第一位置,。请参阅图15，当阀芯31处于排水位置时，转杆3231的位置为第二位置，第一位置和第二位置位于上述的转动轨迹的最低点沿转动方向的相对两侧。
当转杆3231被限定在锁口31a内，弹性件33对转杆3231施加沿进入锁口31a的方向继续转动的力矩，力矩使得转杆3231具有继续沿图15中的顺时针方向转动的趋势，弹性件33的锁口31a对转杆3231施加阻力矩，阻力矩的方向沿图15中的逆时针方向。力矩和阻力矩方向相反，且力矩平衡。如此，使得转杆3231被稳定地限制在锁口31a内。
传动杆机构32的具体结构不限。
示例性地，请参阅图8、图9、图12、图13以及图16，传动杆机构32包括传动杆321、第一拨杆322、复位件34以及转套323，转套323套设于传动杆321的第一端，转杆3231设置于转套323上。
转套323带动转杆3231同步运动，例如，转套323和转杆3231可以是一体成型结构，当然，也可以是分体式结构并固定连接在一起。
第一拨杆322设置于传动杆321的第二端，第一拨杆322用于接收驱动力而带动传动杆321转动，也就是说，第一拨杆322和传动杆321同步转动，两者之间没有相对运动。
第一拨杆322和传动杆321的连接方式不限，只要两者能够实现同步运动即可，例如，可以是一体成型、卡接、螺接、平键连接、花健连接等， 在此不做限制。
示例性地，传动杆321具有初始位置，在初始位置下，传动杆321能够选择性地驱动转杆3231正转或反转，复位件34用于驱动传动杆321空转而复位至初始位置。
需要说明的是，所述的初始位置指的是，排水阀组件3在没有外力作用时，传动杆321和第一拨杆322所处的稳定、平衡位置。
需要说明的是，所述的空转指的是，传动杆321在转动过程中不会带动转套323转动，即转套323保持静止，传动杆321相对转套323转动。
第一拨杆322接收驱动机构2的驱动力而带动传动杆321同步转动，传动杆321驱动转套323转动，进而使得阀芯31在排水位置和密封位置之间切换。
具体地，在内筒11转动过程中，当驱动机构2与第一拨杆322接触，即对第一拨杆322施加驱动力，转杆3231在驱动阀芯31从密封位置运动至排水位置的过程中，弹性件33被压缩而存储势能。当驱动机构2与第一拨杆322分离，使得第一拨杆322失去驱动力时，复位件34能够驱动传动杆321和第一拨杆322复位，当下一次驱动机构2需要拨动第一拨杆322时，驱动机构2会在同一个位置拨动第一拨杆322，如此能够简化传动杆机构32与驱动机构2的驱动配合结构。
驱动机构2的具体设置位置不限，只要能够驱动机构2提供安装位置，使得驱动机构2不会跟随内筒11转动即可。
一实施例中，请参阅图1和图2，驱动机构2设置于外桶12上，第一拨杆322位于内筒11和外桶12之间。
示例性地，请参阅图3，驱动机构2包括第二拨杆22以及动力单元21，动力单元21驱动第二拨杆22选择性地朝向拨杆伸出或收回，在第二拨杆22处于伸出的状态下，第二拨杆22能够选择性地拨动第一拨杆322绕转动 中心线正转或反转。
以下对本申请一实施例的洗涤设备的排水原理进行描述。
请参阅图5，假设内筒11沿图5的顺时针方向转动，第二拨杆22朝向排水阀组件3伸出，第二拨杆22与内筒11之间有相对运动，第二拨杆22相对内筒11的轨迹为圆Ⅰ。第二拨杆22从第一拨杆322的右侧接触第一拨杆322，由于第一拨杆322跟随内筒11继续传动，请参阅图6，第二拨杆22迫使第一拨杆322逆时针转动，第一拨杆322带动传动杆321同步逆时针转动，以驱动阀芯31运动。当第一拨杆322和第二拨杆22脱离后，第一拨杆322在复位件34的作用下顺时针转动复位至如图5所示位置。由于阀芯31的位置已经切换，随后，收回第二拨杆22即可，或者，内筒11转动几圈后再收回第二拨杆22。
即使没有收回第二拨杆22，当内筒11转动下一圈时，第二拨杆22再次拨动第一拨杆322，第一拨杆322和传动杆321会空转，不会改变阀芯31的位置。也就是说，在阀芯31位置已经成功切换的情况下，即使没有收回第二拨杆22，第二拨杆22也不会卡死第一拨杆322，因此，在随后的转动中，第二拨杆22不会影响内筒11的转动，第二拨杆22不会憋死内筒11，也不会误触发阀芯31改变位置。
当内筒11反转，即沿图5的逆时针方向转动，第二拨杆22朝向排水阀组件3伸出，第二拨杆22从第一拨杆322的左侧接触第一拨杆322，第二拨杆22迫使第一拨杆322顺时针转动，第一拨杆322带动传动杆321同步顺时针转动，以驱动阀芯31运动。当第一拨杆322和第二拨杆22脱离，第一拨杆322在复位件34的作用下逆时针转动复位。由于阀芯31的位置已经切换，随后，收回第二拨杆22即可，或者，内筒11转动几圈后再收回第二拨杆22。
需要说明的是，只要第一拨杆322转动的角度能够使得转杆3231转入 锁口31a内，或者从锁口31a转出即可。
示例性地，请参阅图11，沿第一拨杆322的宽度方向，第一拨杆322用于与洗涤设备的驱动机构2接触的外端面322a呈中间高两边低的弧形表面。当第二拨杆22伸出时，有一定的概率会直接抵接在外端面322a上。由于外端面322a呈弧形表面，使得第二拨杆22不会被卡死或破坏。
示例性地，一实施例中，请参阅图7至图9、图12至图16，排水阀组件3包括阀座35，弹性件33、转杆3231、阀芯31的至少一部分设置于阀座35内，阀座35朝向排水孔的一侧敞开；传动杆机构32远离阀芯31的一端位于阀座35的外侧，即第一拨杆322位于阀座35外。
示例性地，请参阅图8和图9，阀座35的侧壁上设置有避让孔35a，传动杆321穿设于避让孔35a中。阀座35为阀芯31和传动杆机构32提供安装支撑，同时也对阀芯31和传动杆机构32起到保护作用，提升排水阀组件3的可靠性。
示例性地，请参阅图8和图9，复位件34为套设于传动杆321上的扭簧，复位件34的两个转臂341与阀座35可分离地抵接，在传动杆321转动过程中，传动杆机构32能够择一地拨动其中一个转臂341跟随运动。
传动杆321在驱动阀芯31运动过程中，传动杆机构32会同步拨动其中一个转臂341运动而使得扭簧存储势能。通过扭簧的两个转臂341来平衡阀座35对扭簧的反作用力，使得传动杆321能够可靠地保持在初始位置。
具体地，阀座35对其中一个转臂341产生第一作用力，对其中另一个转臂341产生第二作用力，扭簧在第一作用力和第二作用力的作用下保持平衡，以维持在初始位置。该实施例中，由于在初始位置下具有预紧力，因此，传动杆321复位过程中，即使传动杆321运动至接近初始位置的附近，扭簧也能具有较大的回复力能够可靠地将传动杆321回复至初始位置，而不会使得传动杆321在初始位置附近摆动或无法回复到初始位置，能够 提升传动杆321和第一拨杆322的复位可靠性。
一实施例中，任意一个转臂341在传动杆机构32的拨动下朝向旋紧扭簧的方向运动。如此，转臂341始终朝向旋紧扭簧的方向运动，一方面，扭簧不容易失效，另一方面，也能使得扭簧具有较大的回弹力。
需要说明的是，所述的朝向旋紧扭簧的方向运动指的是，转臂341的运动方向与扭簧的螺旋方向一致，转臂341运动后会使得扭簧的节距减小。
传动杆机构32可以有任何适当的结构来选择性地拨动两个转臂341。示例性地，一实施例中，请参阅图9，传动杆机构32包括拨动杆3241，拨动杆3241与传动杆321同步运动，拨动杆3241位于两转臂341之间以择一地拨动任意一个转臂341。
两转臂341与阀座35的抵接形式不限。例如，阀座35的底表面设置有凸脊，凸脊沿传动杆321的长度方向延伸，当传动杆321处于初始位置，在垂直于转动中心线的平面投影中，两转臂341交叉后抵接在凸脊的相对两侧，拨动杆3241位于凸脊和两转臂341的交叉点之间。如此，当拨动杆3241沿任意一个方向拨动其中一个转臂341时，转臂341均能朝向旋紧复位件34的方向运动，而且还能使得另一个转臂341可靠地抵接在凸脊的另一侧。
需要说明的是，传动杆321与拨动杆3241的连接方式不限，只要能够实现同步转动即可。一些实施例中，拨动杆3241可以与传动杆321固定连接，例如，一体成型、螺接、卡接等。另一些实施例中，拨动杆3241可相对传动杆321轴向移动。
示例性地，另一些实施例中，请参阅图9，传动杆机构32包括套接件324，套接件324套设于传动杆321上且跟随传动杆321同步转动，拨动杆3241设置于套接件324上。套接件324和传动杆321之间可以通过平键、花键等传动，也可以通过非圆形的周向轮廓实现扭矩传动。该实施例中， 装配时，可以将传动杆321穿过阀座35的侧壁后，再将套接件324直接套在传动杆321上即可，无需螺钉等紧固件进行固定，拆装方便。
示例性地，转套323设置有第一驱动槽，第一驱动槽沿转动方向相对两侧均具有第一驱动面，传动杆321的第一端至少部分位于第一驱动槽中，并能够在第一驱动槽中滑动，传动杆321的第一端能够择一地与其中一个第一驱动面驱动配合以驱动转套323绕转动中心线转动。
需要说明的是，传动杆机构32的转动方向与内筒11的转动方向有关，例如，当内筒11沿图5中的顺时针方向转动时，如果驱动机构2拨动第一拨杆322，则第一拨杆322只会带动传动杆机构32绕转动中心线沿图5的逆时针转动。当内筒11沿图5中的逆时针方向转动时，如果驱动机构2拨动第一拨杆322，则第一拨杆322只会带动传动杆机构32绕转动中心线沿图5中的顺时针转动。
当洗涤设备在洗涤过程中，阀芯31处于密封位置时，传动杆321第一端的与其中一个第一驱动面接触，此时内筒11持续正转，假如驱动机构2误动作而拨动了第一拨杆322，此时，第一拨杆322会带动传动杆机构32沿图5的顺时针方向转动，传动杆321的第一端在第一驱动槽中空转，即第一拨杆322和传动杆321产生空行程，此时，传动杆机构32不会驱动阀芯31运动，阀芯31仍然能保持在当前的密封位置，如此能够提升洗涤设备的可靠性。
当阀芯31处于排水位置，在内筒11不改变转动方向的情况下，假如驱动机构2误动作而拨动了第一拨杆322，此时，第一拨杆322会带动传动杆机构32沿图5的逆时针方向转动，传动杆321的第一端在第一驱动槽中空转，即第一拨杆322和传动杆321产生空行程，传动杆机构32不会驱动阀芯31运动，阀芯31仍然能保持在当前的排水位置，空转后，传动杆321在复位件34的作用下仍然会回到初始位置，如此能够提升洗涤设备的可靠 性。
示例性地，请参阅图10，阀芯31包括固定连接的阀片312和阀柱311，阀片312设置于阀柱311的顶端，阀芯31通过阀片312封堵排水孔，转杆3231与阀柱311驱动配合。
示例性地，请继续参阅图10，阀柱311具有朝向传动杆机构32一侧的定位面311a以及凸出于定位面311a的凸筋3111，凸筋3111包括相互衔接的第一弯曲段31111和第二弯曲段31112，第一弯曲段31111的凹侧形成锁口31a。请参阅图15，当阀芯31处于排水位置，转杆3231位于第一弯曲段31111限定的区域内。请参阅图14，当阀芯31处于密封位置，转杆3231位于第二弯曲段31112限定的区域内。该实施例中，利用凸筋3111和转杆3231的配合实现阀芯31和传动杆机构32的驱动配合，结构简单。
示例性地，请参阅图15，当阀芯31处于排水位置，第一弯曲段31111和第二弯曲段31112位于转杆3231转动轨迹最低点的相对两侧。转杆3231的转动轨迹为一个以转动中心线为中心的圆，图15中的虚线圆圈示意转杆3231的转动轨迹。转杆3231需要具有较大的力才能越过最低点，因此，无论转杆3231在第一弯曲段31111还是第二弯曲段31112的位置处，在没有较大的外力作用下，转杆3231不会越过转动轨迹的最低点，如此，使得转杆3231能够可靠地保持在密封位置或排水位置。
示例性地，当阀芯31处于排水位置，以转杆3231的转动轨迹与第一弯曲段31111的接触点为参考点，第一弯曲段31111位于参考点靠近第二弯曲段31112一侧的部位与转杆3231的转动轨迹的干涉量为第一干涉量，第一弯曲段31111位于参考点远离第二弯曲段31112一侧的部位与转杆3231的转动轨迹的干涉量为第二干涉量，第一干涉量小于第二干涉量。其中，干涉量指的是凸筋3111伸入转动轨迹内的沿径向的长度。
该实施例中，转杆3231从第二弯曲段31112限定的位置转动至第一弯 曲段31111限定的位置时，由于干涉量变大，使得转杆3231不能继续转动，防止转杆3231脱离第一弯曲段31111，对转杆3231进行可靠地限位。
示例性地，请参阅图15和图16，沿阀芯31的平动方向，第一弯曲段31111比第二弯曲段31112更靠近排水孔。也就是说，第一弯曲段31111高于第二弯曲段31112。该实施例中，在阀芯31所需相同的平动行程的情况下，对转杆3231的转动行程要求较低，也就是说，转动3231只需转动较小的行程，即可使得阀芯31获得较大的平动行程，转杆3231所需的转动空间较小，更省空间，使得排水阀组件结构更简单、紧凑。
一实施例中，请参阅图图9以及图10，阀座35和阀芯31的其中之一设置有导向槽35b，其中另一设置有导向筋3112，导向筋3112与导向槽35b滑动配合。如此能够提升阀芯31平动的可靠性，避免阀芯31偏摆。
一实施例中，请参阅图7、图8、图11至图16，排水阀组件3包括柔性密封件36，柔性密封件36罩设于阀座35的敞开侧，柔性密封件36和阀座35共同围设成密封腔3a，阀芯31、弹性件33、转杆3231均位于密封腔3a内，阀芯31与柔性密封件36连接以带动柔性密封件36运动。
由于阀芯31、弹性件33、转杆3231等均设置于密封腔3a内，因而不会接触洗涤水，一方面，洗涤水中的毛屑不会进入密封腔3a，避免毛屑等杂质堵塞或缠绕在转杆和阀芯31上，能够保障排水阀的正常运动，提升密封阀组件的工作可靠性和使用寿命；另一方面，在传动杆机构32或阀芯31采用金属材质的情况，还能够避免洗涤水对金属材质的腐蚀作用。
需要说明的是，柔性密封件36可以为一体成型结构，以提升柔性密封件36的结构可靠性。柔性密封件36的材质不限，例如，包括但不限于：硅胶、橡胶等。
示例性地，请参阅图7、图12至图16，柔性密封件36包括支撑筒部361以及端盖部362，支撑筒部361的第一端密封地罩设于阀座35的敞开 处，端盖部362封闭支撑筒部361的第二端，阀芯31设置于密封腔3a内且与端盖部362连接。
一些实施例中，请参阅图16，支撑筒部361呈波纹管状。通过支撑筒部361的伸缩折叠来适应阀芯31的运动。
另一些实施例中，请参阅图13和图15，当阀芯31处于排水位置，端盖部362凹入支撑筒部361内。该实施例中，通过端盖部362凹入、回弹来实现柔性密封件36跟随阀芯31运动，避免支撑筒部361产生褶皱，避免支撑筒部361夹住毛絮等杂质，降低因褶皱造成细菌滋生或影响排水阀组件3的可靠性的几率。
示例性地，请参阅图7、图12和图14，支撑筒部361的周向外表面为光滑表面，在阀芯31带动端盖部362运动过程中，支撑筒部361不发生伸缩变形。如此，使得混杂在洗涤水中的毛絮等杂质不容易堆积在柔性密封件36上。
示例性地，请参阅图7、图12至图16，柔性密封件36包括密封唇363，密封唇363设置于端盖部362背离密封腔3a的外侧，当阀芯31处于密封位置，阀芯31将密封唇363密封地抵靠在排水孔周围。密封唇363能够可靠地与内筒11密封接触，降低对阀片312的精度要求。
示例性地，请参阅图12和图16，端盖部362位于密封唇363环绕范围内的部位设置有贯穿端盖部362的透气孔362a，透气孔362a构造为：水流不能经透气孔362a进入密封腔3a内。当阀芯31从密封位置运动至排水位置，密封腔3a的体积会变小，因此，密封腔3a内的空气会受到压缩，多余的空气经透气孔362a排出，降低气压阻力。
示例性地，透气孔362a的孔径不超过0.8mm。如此，透气孔362a能允许气流通过，在表面张力作用下，水流无法通过透气孔362a。
可以理解的是，还可以通过设置单向阀等方式实现透气孔362a仅允许 气流通过而不允许水流通过的功能。
柔性密封件36与阀座35的具体连接方式不限。
示例性地，请参阅图7至图16，排水阀组件3包括压板37，压板37将支撑筒部361的底端边缘压紧在阀座35上，再通过螺钉、螺栓等紧固件紧固连接即可。
排水阀组件3的设置位置不限。
一实施例中，请参阅图2至图4，洗涤设备包括提升筋13，阀芯31、弹性定位件以及弹性复位件34均设置于提升筋13内，传动杆321的第一端位于提升筋13内，传动杆321的第二端延伸至内筒11沿轴向一端的外侧，第一拨杆322位于内筒11沿轴向一端的外侧。需要说明的是，在排水阀组件3包括阀座35的实施例中，阀座35也设置在提升筋13内，且阀座35与提升筋13固定连接。
在洗涤设备洗涤衣物的过程中，提升筋13携带衣物一起转动，衣物被提升至一定高度后，在自身重力作用下用重新跌入水中，产生棒打、摔跌作用，从而达到洗涤效果。一方面，提升筋13对排水阀组件3起到保护作用，防止衣物缠绕在排水阀组件3上。另一方面，充分利用了洗涤设备现有结构，充分利用提升筋13内部的空间，不会降低内筒11洗涤衣物的容量。
示例性地，洗涤设备包括设置于外桶12上的检测组件，请参阅图8、图12和图13，排水阀组件3包括设置于阀芯31上的磁体38，例如，磁体38嵌入阀片31中。检测组件能够检测磁体38的当前位置，检测组件和磁体38为无接触式检测感应，避免检测组件与磁体38之间设置接线等物理连接，从而避免内筒11转动。
检测组件能够输出表征阀芯31当前位置的位置信息，控制装置根据位置信息控制内筒11洗涤和/或脱水。
检测组件检测磁体38的磁场强度，以获取阀芯31的当前位置。磁体38形成稳定磁场，阀芯31在密封位置和排水位置之间切换过程中会使得磁体38与检测组件之间的距离改变，阀芯31在密封位置或排水位置时，磁体38与检测组件之间的距离不同，检测组件检测的磁场强度不同，以此获知磁体38的位置，从而获取阀芯31的当前位置。
控制装置根据位置信息确认阀芯31所处的位置，从而确认排水孔被密封还是打开，以便准确控制内筒11执行洗涤操作或脱水操作，保证内筒11执行脱水操作时，排水阀组件处于排水位置，内筒11执行洗涤操作时，排水阀组件处于密封位置，避免排水阀组件所处位置不当，影响内筒11洗涤和脱水。
一实施例中，检测组件设置于排水孔在外桶12上掠过的圆形轨迹上。即排水孔随内筒11转动形成的转动轨迹在外桶12上投射形成圆形轨迹，也就是说，排水孔随内筒11转动形成的转动轨迹和圆形轨迹为同心圆，检测组件设置于圆形轨迹上，如此，内筒11转动过程中，排水阀组件3必然会在某一位置对准检测组件，从而保证检测组件能够检测到排水阀组件3的当前位置。也就是说，在洗涤或脱水开始的时候，内筒11处于低速转动的状态，排水阀组件3随内筒11低速转动，排水阀组件3在转动过程中，必然在某一位置对准检测组件，从而使得检测组件能够检测到排水阀组件3的当前位置。
