具体实施方式
下面结合附图对本申请的一种衣物处理剂投放装置及洗衣机进行详细描述：
本实施例的一种衣物处理剂投放装置，包括：
至少两个投放腔室，分别具有出液口，出液口内分别设置出液单向导通部件；
活塞机构，可往复运动的设置在投放腔室内；
驱动机构，包括主动部件、切换部件以及从动部件，从动部件包括多个，分别与投放腔室一一对应，从动部件与活塞机构传动连接；
主动部件通过切换部件切换与不同从动部件的传动连接，驱动从动部件带动与之对应的投放腔室内的活塞机构运动，将出液单向导通部件导通进行衣物处理剂的投放。
本实施例的衣物处理剂投放装置的驱动机构由一个主动部件将动力分配至不同的从动部件，从动部件带动与之对应的投放腔室内的活塞机构运动，将出液单向导通部件导通进行衣物处理剂的投放，实现了单动力多驱动的投放方式，这样提高了动力部件的利用率，降低了衣物处理剂投放装置的整体成本，具有 广阔的市场前景。
本实施例所述的切换部件包括活动件，所述的活动件与主动部件传动连接，且可在不同从动部件之间运动进行传动连接，以将主动部件的动力传递至不同从动部件进行对应投放腔室的衣物处理剂投放。
本实施例通过可在不同从动部件之间运动的活动件，将主动部件的运动传递至每个从动部件，从动部件带动与之对应的投放腔室内的活塞机构运动，将出液单向导通部件导通进行衣物处理剂的投放。活动件可在主动部件的驱动下进行运动，通过改变主动部件的运转方式(例如转向)施加给活动件不同方向的受力，改变其运动的方向。总之，本申请通过一个活动件解决了单一主动部件向不同从动部件进行动力传递的问题，实现本申请单动力多驱动的投放方式。
作为本实施例的一种实施方式，如图1-图3所示，所述的主动部件包括主动齿轮3，所述的从动部件包括从动齿轮(如图中的附图标记6、23)，所述的活塞机构包括活塞(如图中的附图标记10、19)和活塞杆(如图中的附图标记8、21)，活塞杆(如图中的附图标记8、21)的一端与从动齿轮(如图中的附图标记6、23)偏心可转动的连接；所述的活动件为活动齿轮4，活动齿轮4与主动齿轮3保持啮合传动，且可在不同从动齿轮(如图中的附图标记6、23)之间运动进行啮合传动。
本实施例的活动齿轮4与主动齿轮3保持啮合传动，确保动力由主动齿轮3始终能够传递给活动齿轮4，而活动齿轮4在不同从动齿轮(如图中的附图标记6、23)之间运动进行啮合，以将主动轮3的动力择一的传递给对应的从动齿轮(如图中的附图标记6、23)。
本实施例的活塞杆(如图中的附图标记8、21)的一端与从动齿轮(如图中的附图标记6、23)偏心可转动的连接，从动齿轮(如图中的附图标记6、23)带动活塞机构运动，这样从动部件可将主动部件的转动转化为活塞机构的往复直线运动，进行投放腔室内的衣物处理剂的投放。

为了确保活动齿轮4与一从动齿轮啮合传动的稳定性，本实施例的活动齿轮轴25在滑槽26滑动至与一从动齿轮相啮合的位置时保持限位，因此，本申请所述的滑槽26具有多个限位部，分别与从动齿轮一一对应，所述的活动齿轮轴沿滑槽滑26运动至每个限位部内，活动齿轮4与相对应的从动齿轮啮合传动。
如本实施例附图所示，本申请具有两个从动齿轮，本申请的滑槽26的两端分别为两个限位部，限定活动齿轮轴25的运动，确保活动齿轮4与一从动齿轮啮合传动的稳定性。
由于活动齿轮4需要保持与主动齿轮3的啮合传动，应尽量减小活动齿轮4的运动幅度，确保与主动齿轮3啮合传动的稳定性，本申请所述切换部件还包括传递齿轮5，所述的活动齿轮4与至少一个从动齿轮直接啮合传动，与其它的从动齿轮通过传递齿轮啮合传动。本实施例通过增加传递齿轮5，可以减小活动齿轮4移动的距离，增加了驱动机构整个动力传递的稳定性。

本实施例的驱动机构的驱动电机可以进行正反转，通过控制驱动电机的正反转控制第一投放腔室和第二投放腔室内不同种类的衣物处理剂在不同时间进行投放。
在一些实施例中，具有如图1-2的衣物处理剂投放装置的洗衣机的控制方法为：
驱动电机正转(顺时针)：
驱动电机驱动传动部件2正转，驱动主动齿轮3顺时针旋转，驱动活动齿4逆时针旋转，且活动齿轮4在力的作用下，活动齿轮轴25在滑槽26中移动，实现活动齿4与第二从动齿轮23啮合，驱动第二从动齿轮23逆时针旋转,第二从动齿轮23上具有第二连接柱22，实现旋转运动，转变为第二活塞杆21的上下运动，经第二活塞杆21连接第二投放腔室20内的第二活塞19，第二进液单向阀16、第二出液单向阀18在活塞机构往复运动过程中分别单向导通，储放腔室内的衣物处理剂由进液口吸入投放腔室，由出液口排出投放。
驱动电机反转(逆时针)：
驱动电机驱动传动部件2反转，驱动主动齿轮3逆时针旋转，驱动活动齿轮4顺时针旋转，且活动齿轮4在力的作用下，活动齿轮轴25在滑槽26中移动，实现活动齿轮4与传递齿轮5啮合，驱动传递齿轮5逆时针旋转，传递齿轮5与第一从动齿轮6啮合传动，驱动第一从动齿轮6逆时针旋转，第一从动齿轮6上具有第一连接柱7，实现旋转运动，转变为第一活塞杆8的上下运动，经第一活塞杆8连接第一投放腔室9内的第一活塞10，第一进液单向阀11、第一出液单向阀13在活塞机构往复运动过程中分别单向导通，储放腔室内的衣物处理剂由进液口吸入投放腔室，由出液口排出投放。
具有如图3的衣物处理剂投放装置的洗衣机的控制方法也是通过控制驱动的电机正反转来实现，区别仅在于驱动电机直接驱动主动齿轮3的正反转。
可在衣物投放进內桶后进行衣物称重，并根据衣物重量确定衣物处理剂的投放量，控制衣物处理装置按照投放量进行定量投放。
也或者，用户可选择投入衣物处理剂的量，根据用户的选择控制衣物处理装置按照投放量进行定量投放。
本申请的衣物处理剂投放装置的驱动机构由一个主动部件将动力分配至不同的从动部件，从动部件带动与之对应的投放腔室内的活塞机构运动，将出液单向导通部件导通进行衣物处理剂的投放，实现了单动力多驱动的投放方式，这样提高了动力部件的利用率，降低了衣物处理剂投放装置的整体成本，具有广阔的市场前景。
