具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图来详细描述根据本发明实施例的用于洗衣机的自动投放系统。
如图1至图3所示，根据本发明实施例的用于洗衣机的自动投放系统，包括：洗涤剂存储盒10，电磁转向阀和投放泵40。所述电磁转向阀包括中转盒20和电磁切换单元30。这里，所述中转盒20和电磁切换单元30集成在一起，整体形成所述电磁转向阀。
具体地说，洗涤剂存储盒10内限定有多个洗涤剂存储腔室11，12。如图1所示，可以是两个洗涤剂存储腔室11和12。当然，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的数量，例如，可以是三个、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，这里的洗涤剂包括洗涤剂、消毒剂或柔顺剂等，即洗涤剂泛指用于洗衣机中用于洗涤的液体。
中转盒20具有多个进液口21，22和一个出液口23。洗涤剂存储盒10与中转盒20连通且多个进液口21，22与多个洗涤剂存储腔室11，12一一对应。即如图1所示，洗涤剂存储腔室11与进液口21对应，洗涤剂存储腔室12与进液口22对应。当洗涤剂存储腔室的数量在图1的基础上增加时，进液口的数量也相应增加。
电磁切换单元30用于选择性地将多个进液口21，22中的其中一个与一个出液口23连通。
投放泵40具有进口41和出口42。投放泵40的进口41与一个出液口23相连。
根据本发明实施例的用于洗衣机的自动投放系统，通过电磁切换单元选择性地将多个进液口中的一个与出液口连通，采用一个投放泵即可投放多种洗涤剂，结构简单，成本降低。
电磁切换单元30可以包括与多个进液口一一对应多个开关。例如，通过打开和关闭开关来选择性地将多个进液口21，22中的一个与出液口23连通。
有利地，基于自动控制的需要，根据本发明的一个具体示例，电磁切换单元30可以包括与多个进液口21，22一一对应的多个电磁阀31，32。
进一步地，根据本发明的一个示例，电磁阀31包括：电磁铁311，铁芯312和弹簧313。具体地，电磁铁31内限定有开口向下(即如图3中所示的下方)的通道。铁芯312可上下移动地设在所述通道内。弹簧313的上端抵靠所述通道的顶壁且弹簧313的下端抵靠铁芯312的上端以向下常推动铁芯312的下端封闭进液口21。电磁阀31还包括密封垫314，密封垫314设在铁芯312的下端与进液口21之间。
电磁阀32包括：电磁铁321，铁芯322和弹簧323。具体地，电磁铁32内限定有开口向下2的通道。铁芯322可上下移动地设在所述通道内。弹簧323的上端抵靠所述通道的顶壁且弹簧323的下端抵靠铁芯322的上端以向下常推动铁芯322的下端封闭进液口22。电磁阀32还包括密封垫324，密封垫324设在铁芯322的下端与进液口22之间。
密封垫314，324可以为橡胶密封垫。
当洗涤剂存储腔室的数量和进液口的数量在图1的基础上对应增加时，电磁阀的数量也相应增加。
根据本发明的一个示例，所述用于洗衣机的自动投放系统还包括冲洗支路50，中转盒20上还设有进水口24，冲洗支路50的输出端与进水口24相连。有利地，冲洗支路50上设有进水阀51。
下面简单介绍根据本发明实施例的用于洗衣机的自动投放系统的工作过程。
当需要投放洗涤剂存储腔室11内的洗涤剂时，使电磁铁311得电，铁芯312被电磁铁311的吸力吸引，克服弹簧313的弹力向上移动，进液口21与出液口23连通，投放泵40 即可投放洗涤剂存储腔室11内的洗涤剂。洗涤剂投放结束，使电磁铁311失电，铁芯312在弹簧313的回复力的作用下向下移动，铁芯312的下端封闭进液口21。为了尽可能不浪费洗涤剂，也为了避免不同洗涤剂之间互相影响，当洗涤剂投放结束后，可以使冲洗支路对中转盒20进行冲洗，冲洗液也可以经投放泵40进入洗涤桶50中参与洗涤。
投放洗涤剂存储腔室12内的洗涤剂的过程与投放洗涤剂存储腔室11内的洗涤剂的过程相同，在此不再赘述。
如图1所示，根据本发明实施例的洗衣机，包括：洗涤桶60和根据上述任一项所述的用于洗衣机的自动投放系统。其中，投放泵40的出口42与洗涤桶60相连。
