参照图1，根据本发明实施例的复合洗衣机10，包括：第一洗涤桶11a、第二洗涤桶11b以及自动投放系统。
具体而言，如图1所示，自动投放系统包括：洗涤剂存储盒20、换向阀30、投放泵40和三通阀50。
洗涤剂存储盒20内可以限定有多个洗涤剂存储腔室21。例如，如图1所示，洗涤剂存储盒20内可以限定有两个洗涤剂存储腔室21，两个洗涤剂存储腔室21内可以存储不同种类的洗涤剂。当然，也可以根据洗涤剂的种类在图1所示实施例的基础上增加洗涤剂存储腔室21的数量，例如，洗涤剂存储腔室21可以为三个、四个等，这对于本领域技术人员来说是可以理解的。需要注意的是，这里的洗涤剂可以包括洗涤剂、消毒剂或柔顺剂等，即洗涤剂泛指用于洗涤衣物的液体。
换向阀30可以包括出液口34和多个进液口31，洗涤剂存储盒20与换向阀30连通，多个进液口31分别与多个洗涤剂存储腔室21一一对应。也就是说，洗涤剂存储腔室21内的洗涤剂可以通过相应的进液口31进入到换向阀30内，再从出液口34流出。
投放泵40可以具有进口41和出口42，投放泵40的进口41与出液口34相连，出液口 34与其中一个进液口31相连通且与其余的进液口31断开，以使投放泵40将选定的洗涤剂泵送至投放泵40的出口42。也就是说，在同一时刻，投放泵40仅能将一种洗涤剂泵送至相应的洗涤桶内。当多个进液口31中的一个与相应的洗涤剂存储腔室21连通时，在投放泵40的作用下，储存在该洗涤剂存储腔室21内的洗涤剂可以通过相应的进液口31进入到换向阀30内，并通过出液口34流入到投放泵40内。
三通阀50可以包括进水阀口51、第一出水阀口52a和第二出水阀口52b，第一出水阀口52a与第一洗涤桶11a连通，第二出水阀口52b与第二洗涤桶11b连通，当进水阀口51与第一出水阀口52a连通时，进水阀口51与第二出水阀口52b断开，以使投放泵40将选定的洗涤剂泵送至相应的第一洗涤桶11a内；当进水阀口51与第二出水阀口52b连通时，进水阀口51与第一出水阀口52a断开，以使投放泵40将选定的洗涤剂泵送至相应的第二洗涤桶11b内。当多个进液口31中的一个与相应的洗涤剂存储腔室21连通时，三通阀50的进水阀口51与多个出水阀口52中的一个连通，进水阀口51与其余出水阀口52断开，在投放泵40的作用下，储存在该洗涤剂存储腔室21内的洗涤剂可以通过相应的进液口31进入到换向阀30内，并通过出液口34流入到投放泵40内，投放泵40内的洗涤剂从出口42流出后通过进水阀口51流入到三通阀50内，洗涤剂从进水阀口51流向相应的出水阀口52，并从相应的出水阀口52流入到对应的洗涤桶内。
如图1至图3所示，下面详细描述根据本发明实施例的复合洗衣机10的自动投放系统的投放过程，复合洗衣机10可以包括两个洗涤桶，其中一个设在复合洗衣机10的上部为第一洗涤桶11a，另外一个设在复合洗衣机10的下部为第二洗涤桶11b，具体如下：
第一，洗涤桶在洗涤衣物之前，其中一个洗涤剂存储腔室21与换向阀30的进液口31连通，其余洗涤剂存储腔室21与换向阀30的进液口31断开，其中一个洗涤剂存储腔室21内的洗涤剂可以从相应的进液口31进入到换向阀30内，并从换向阀30的出液口34流出，洗涤剂在投放泵40的作用下，流经投放泵40，并通过三通阀50上与洗涤桶连通的出水阀口52进入到洗涤桶内；
第二，当洗涤桶洗涤过程完成后，其中另一个洗涤剂存储腔室21与换向阀30的进液口31连通，其余洗涤剂存储腔室21与换向阀30的进液口31断开，其中另一个洗涤剂存储腔室21内的洗涤剂可以从相应进液口31进入到换向阀30内，并从换向阀30的出液口34流出，洗涤剂在投放泵40的作用下，流经投放泵40，并通过三通阀50上与洗涤桶连通的出水阀口52进入到洗涤桶内。至此，完成了对复合洗衣机10的洗涤桶的洗涤剂的投放过程。
根据本发明实施例的复合洗衣机10，自动投放系统可以利用换向阀30使多个洗涤剂存储腔室21中的一个与出液口34连通，再利用三通阀50使出液口34与相应的洗涤桶连通，从而可以按顺序将不同洗涤剂投放至相同洗涤桶内或不同洗涤桶内，或者将相同洗涤剂按 顺序投放至相同洗涤桶内或不同的洗涤桶内，由此易于实现复合洗衣机10中洗涤剂的自动投放，从而可以取代手动添加洗涤剂的操作，提高复合洗衣机10的使用性能。
结合图1，根据本发明的一个实施例，自动投放系统还可以包括冲洗支路60，冲洗支路60上设有进水阀61以控制冲洗支路60断开或连通，冲洗支路60与进水阀口51连通。由此，自动投放系统投放完一种洗涤剂后，可以利用冲洗支路60对自动投放系统进行冲洗，从而可以降低不同种类的洗涤剂相互混合的可能性，从而可以有效地提高自动投放系统的洗涤剂投放效果，满足复合洗衣机10的使用需求。
进一步地，冲洗支路60可以通过投放泵40的进口41与进水阀口51连通。由此，冲洗支路60可以对投放泵40、三通阀50、连接在上述部件之间的连通管以及连接在三通阀50和洗涤桶之间的连通管进行冲洗，从而可以减少残留在投放泵40内、三通阀50内、连接在上述部件之间的连通管内以及连接在三通阀50和洗涤桶之间的连通管内的洗涤剂浓度，从而可以有效地提高自动投放系统的洗涤剂投放效果，满足复合洗衣机10的使用需求。
进一步地，换向阀30可以包括进水口33，冲洗支路60可以通过进水口33与投放泵40的进口41连通，洗涤剂从其中一个进液口31泵送至投放泵40的出口42之后，选择性地将冲洗支路60与进水口33相连通以通过进水阀61将水经进水口33、出液口34泵送至出口42。
需要说明的是，在洗涤剂从其中一个进液口31泵送至投放泵40的出口42，以及三通阀50的出水阀口52后，由于经常性使用洗涤剂会堵塞换向阀30和/或投放泵40和/或三通阀50，通过选择性地将进水阀61与换向阀30的进水口33相连通并通过进水阀61将水经进水口33、出液口34泵送至出口42，进而经三通阀50的进水阀口51，出水阀口52送至复合洗衣机10的洗涤桶内参与洗涤。这样不仅可以起到清洗的作用，也不会出现因使用洗涤剂而堵塞换向阀30和/或投放泵40和/或三通阀50的问题。
根据本发明的一个实施例，三通阀50可以为Y型电磁阀。由此，可以通过Y型电磁阀的阀口实现对洗涤桶内洗涤剂投放的控制。
上述对三通阀50的描述只是示例性的，不能理解为对本发明的限制，在本发明的其他实施例中三通阀50也可以是其他的电磁阀，本发明对三通阀50的具体形式不作限定，实际应用中可以根据需要适应性选择。
根据本发明的一个实施例，换向阀30可以为电磁转向阀。由此便于实现自动投放系统的自动化控制。
进一步地，电磁转向阀可以包括电磁切换单元，电磁切换单元包括与多个进液口31一一对应的多个电磁阀，由此便于控制多个进液口31打开与关闭。
更进一步地，每个电磁阀包括：电磁铁、铁芯以及弹簧。其中，电磁铁内限定有开口向下的通道；铁芯可上下移动地设在通道内；弹簧的上端抵靠通道的顶壁且弹簧的下端抵 靠铁芯的上端以向下常推动铁芯的下端封闭对应的进液口31。
需要说明的是，通过换向阀30中电磁控制组件的动作控制出液口34与其中一个进液口31相连通且与其余的进液口31断开，在投放泵40的作用下，洗涤剂存储腔室21内的洗涤剂通过进液口31进入到换向阀30内，并经过投放泵40后进入到三通阀50内，三通阀50的相应的出水阀口52与相应的洗涤桶连通，由此可以将洗涤剂投放至相应的洗涤桶内。
下面参照图1至图3以具体的实施例详细描述根据本发明实施例的复合洗衣机10。值得理解的是，下述描述只是示例性说明，而不是对本发明的具体限制。
如图1所示，复合洗衣机10可以包括两个洗涤桶，其中一个设在复合洗衣机10的上部为第一洗涤桶11a，另外一个设在复合洗衣机10的下部为第二洗涤桶11b。复合洗衣机10的自动投放系统包括：洗涤剂存储盒20、换向阀30、投放泵40、三通阀50以及冲洗支路60。
如图1所示，洗涤剂存储盒20内设有两个洗涤剂存储腔室21，位于左侧(如图1所示侧左侧)的洗涤剂存储腔室21可以用于盛放有洗衣液，位于右侧(如图1所示的右侧)的洗涤剂存储腔室21可以用于盛放柔顺剂。换向阀30可以为电磁转向阀，换向阀30上设有一个进水口33、一个出液口34以及两个进液口31，其中，进水口33通过进水阀61与冲洗支路60连通，出液口34与投放泵40的进口41连通，两个进液口31中的一个与一个洗涤剂存储腔室21连通，两个进液口31中的另一个与另一个洗涤剂存储腔室21连通。
如图2、图3所示，三通阀50可以包括一个进水阀口51、第一出水阀口52a和第二出水阀口52b，进水阀口51与投放泵40的出口42连通，第一出水阀口52a与第一洗涤桶11a连通，第二出水阀口52b与第二洗涤桶11b连通。当进水阀口51与第一出水阀口52a连通时，进水阀口51与第二出水阀口52b断开；当进水阀口51与第二出水阀口52b连通时，进水阀口51与第一出水阀口52a断开。
当复合洗衣机10的第二洗涤桶11b洗涤衣物时，可以选定洗涤剂的投放顺序为：在洗涤衣物之前，先向第二洗涤桶11b投放洗衣液，当衣物洗涤过程结束后，再向第二洗涤桶11b投放柔顺剂；当复合洗衣机10的第一洗涤桶11a洗涤衣物时，可以选定洗涤剂的投放顺序为：在洗涤衣物之前，先向第一洗涤桶11a投放洗衣液，当衣物洗涤过程结束后，再向第一洗涤桶11a投放柔顺剂；当复合洗衣机10的第一洗涤桶11a和第二洗涤桶11b同时洗涤衣物时，在洗涤衣物之前，可以先向第一洗涤桶11a和第二洗涤桶11b中的一个投放洗衣液，再向第一洗涤桶11a和第二洗涤桶11b中的另一个投放洗衣液，当衣物洗涤过程结束后，向相应的洗涤桶内投放柔顺剂。
如图1-图3所示，下面以第二洗涤桶11b洗涤衣物的过程为例详细描述根据本发明实施例的复合洗衣机10中自动投放系统的投放过程，具体如下：
第一，第二洗涤桶11b在洗涤衣物之前，冲洗支路60与进水口33断开，位于右侧的洗涤剂存储腔室21与换向阀30的进液口31断开，位于左侧的洗涤剂存储腔室21与换向阀30的进液口31连通，位于左侧的洗涤剂存储腔室21内的洗衣液可以从进液口31进入到换向阀30内，并从换向阀30的出液口34流出，洗衣液在投放泵40的作用下，流经投放泵40，并通过三通阀50上与第二洗涤桶11b连通的出水阀口52进入到第二洗涤桶11b内；
第二，当第二洗涤桶11b洗涤过程完成后，进液口31与洗涤剂存储腔室21均断开，冲洗支路60通过进水阀61与换向阀30的进水口33连通，冲洗支路60内的水流可以通过进水口33依次经过换向阀30、投放泵40、三通阀50进入到第二洗涤桶11b内，从而可以对换向阀30、投放泵40、三通阀50进行冲洗；
第三，冲洗完成后，冲洗支路60与进水口33断开，位于左侧的洗涤剂存储腔室21与换向阀30的进液口31断开，位于右侧的洗涤剂存储腔室21与换向阀30的进液口31连通，位于右侧的洗涤剂存储腔室21内的柔顺剂可以从进液口31进入到换向阀30内，并从换向阀30的出液口34流出，柔顺剂在投放泵40的作用下，流经投放泵40，并通过三通阀50上与第二洗涤桶11b连通的出水阀口52进入到第二洗涤桶11b内；
第四，柔顺剂投放完成后，进液口31与洗涤剂存储腔室21均断开，冲洗支路60通过进水阀61与换向阀30的进水口33连通，冲洗支路60内的水流可以通过进水口33依次经过换向阀30、投放泵40、三通阀50进入到第二洗涤桶11b内，从而可以对换向阀30、投放泵40、三通阀50进行冲洗。
至此，完成后了对复合洗衣机10的第二洗涤桶11b的洗涤剂的投放过程。
需要说明的是，对复合洗衣机10的第一洗涤桶11a的洗涤剂的投放过程、对复合洗衣机10的第一洗涤桶11a和第二洗涤桶11b同时投放洗涤剂的过程与上述过程类似，这里不再详细赘述。
