在本申请的描述中，涉及到“一些实施例”，其描述了所有可能实施例的子集，但是可以理解，“一些实施例”可以是所有可能实施例的相同子集或不同子集，并且可以在不冲突的情况下相互结合。
在本申请的描述中，所涉及的术语“第一、第二”等仅仅是区别类似的对象，不代表针对对象的特定排序，可以理解地，“第一、第二”等在允许的情况下可以互换特定的顺序或先后次序，以使这里描述的本申请实施例能够以除了在这里图示或描述的以外的顺序实施。除非另有说明，“多个”的含义是至少两个。
在本申请的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征之“上” 或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
本申请实施例提供一种洗涤剂投放装置，该洗涤剂投放装置可以利用水流作为动力源，实现洗涤剂的自动投放。如图1至图9所示，该洗涤剂投放装置，包括：第一腔室1A、第二腔室1C、转动机构2、减速机构3、动力分配机构4及配给机构。其中，第一腔室1A具有第一进水口1011和第二进水口1012，第二腔室1C具有第一进液口1016和第二进液口1018。转动机构2设置于第一腔室1A内。减速机构3连接转动机构2，用于将转动机构2输出的动力减速增扭后输出。动力分配机构4连接减速机构3的输出端，动力分配机构4具有传递减速机构3输出的动力的第一输出端及第二输出端。配给机构包括第一配给机构5和第二配给机构6，第一配给机构5连接第一输出端，用于控制第一进液口1016处洗涤剂的投放；第二配给机构6连接第二输出端，用于控制第二进液口1018处洗涤剂的投放。
由于转动机构2可以由经第一进水口1011或者第二进水口1012流入第一腔室1A内的水流驱动，转动机构2输出的动力经减速机构3减速增扭后输出给动力分配机构4，由动力分配机构4驱动第一配给机构5控制第一进液口1016处洗涤剂的投放或者驱动第二配给机构6控制第二进液口1018处洗涤剂的投放，如此，洗涤剂投放装置可以利用水流作为动力源，实现洗涤剂的自动投放，可以省去电动驱动装置，从而节省成本。这里，洗涤剂可以为洗涤所需的液态或者粉末状的洗涤产品，本领域技术人员可以根据需求进行合理选择，本申请对此不做具体限定。
此外，需要说明的是，由于水流的水压会在使用过程中发生波动，本申请实施例中，转动机构2输出动力经减速机构3减速增扭后传递给动力分配机构4，可以有效拓宽水流水压的工作范围，使得低水压状态下的水流驱动转动机构2后，由减速机构3减速增扭，从而增大动力分配机构4输出的扭矩，使得第一配给机构5或者第二配给机构6可以有效地控制各自的进液口处洗涤剂的投放，从而实现洗涤剂的自动投放，且由于第一配给机构5控制第一进液口1016处洗涤剂的投放、第二配给机构6控制第二进液口处洗涤剂的投放，可以实现不同种类的洗涤剂的分类自动投放，从而进一步节省了分类自动投放的控制成本。
示例性地，如图1和图2所示，洗涤剂投放装置包括：壳体1，壳体1内形成互相间隔设置的第一腔室1A和第二腔室1C。第一进水口1011和第二进水口1012位于壳体1的第一侧，出水口1013位于壳体1的第二侧，若水流由第一进水口1011流入并由出水口1013流出，则驱动转动机构2沿第一方向转动；若水流由第二进水口1012流入并由出水口1013流出，则驱动转动机构2沿第二方向转动。
示例性地，第一进水口1011和第二进水口1012位于壳体1的第一侧(即图2所示的左侧)，出水口1013位于壳体1上与第一侧相对的第二侧(即图2所示的右侧)；若水流由第一进水口1011流入并由出水口1013流出，则驱动转动机构2沿第一方向(如图2所示的顺时针方向)转动；若水流由第二进水口1012流入并由出水口1013流出，则驱动转动机构2沿第二方向(如图2所示的逆时针方向)转动。可以理解的是，若水流以相近的流量同时进入第一进水口1011和第二进水口1012，则转动机构2的动力互相抵消，即可以维持不动的状态，但水流可以正常由出水口1013流出。如此，通过控制第一进水口1011和第二进水进口1012的供水状态，可以在第一腔室1A正常供水的情形下，实现转动机构2的顺时针转动、逆时针 转动及静止状态的切换。实际应用中，第一进水口1011、第二进水口1012可以经电磁阀连通供水水路，通过电磁阀控制第一进水口1011、第二进水口1012的供水状态，则可以有效控制转动机构2的转动状态。
可以理解的是，出水口1013的数量可以为多个，本领域技术人员可以根据需求进行合理设置，在此不做限定。
可以理解的是，本领域技术人员可以根据需求进行合理设置出水口1013的位置，在此不做限定。比如：出水口1013所在的一侧可以与第一进水口1011、第二进水口1012所在的一侧相互垂直设置，或者相对设置。
在一些实施例中，如图2所示，第一腔室1A大致形成为圆柱形腔室，第一腔室1A的第一侧向外延伸形成第一进水管1020及第二进水管1021，第一进水管1020及第二进水管1021平行设置且分别位于第一腔室1A的上下两端，第一腔室1A的第二侧向外延伸形成出水管1022，出水管1022位于第一腔室1A的中部。
示例性地，第一进水管1020的入口处形成第一进水口1011，第二进水管1021的入口处形成第二进水口1012，出水管1022的出口处形成出水口1013；水流由第一进水口1011流入，则驱动转动机构2沿第一方向转动；水流由第二进水口1012流入，则驱动转动机构2沿第二方向转动。
可以理解的是，转动机构2可以为在水流驱动下旋转的叶轮，比如：涡轮或者螺旋桨。转动机构2只要能够在第一腔室1A内流经的水流的作用下转动，输出动力即可，本申请对此不做具体限定。
在一些实施例中，如图1及图2所示，转动机构2包括叶轮21，叶轮21的转动轴垂直设于腔室1A内，第一进水口1011、第二进水口1012位于叶轮21的一侧，出水口1013位于叶轮21的另一侧，水流经第一进水口1011或者第二进水口1012进入后适于推动叶轮21转动，并经出水口1013流出；叶轮21的转动轴与减速机构3的输入端相连。如此，叶轮21可以在水流 驱动下旋转，从而将水能转换为机械能。这里，叶轮21包括固定于输出轴上的多个叶片211，叶片211可以为曲面叶片或者直面叶片，其中，直面叶片是指叶片的表面呈平面状，以与水流的驱动下转动；曲面叶片是指叶片的表面呈曲面状，从而使得叶片的末端具有设定的弧度，利于形成旋转的涡流。
示例性地，如图1及图2所示，壳体1包括外壳101及第一端盖102，第一端盖102与外壳101配合形成第一腔室1A，第一进水口1011和第二进水口1012间隔设置于图2所示的外壳101的左侧，比如，第一进水口1011与第二进水口1012在外壳101的外侧呈上下间隔分布；出水口1013设置于如图2所示的外壳101的右侧。例如，水流的方向沿图2的箭头所示，位于第一腔室1A内的转动机构2在水流的压力作用下沿顺时针方向转动、沿逆时针方向转动或者压力相抵时静止并维持正常供水。
可以理解的是，减速机构3可以包括但不限于：齿轮减速器、蜗轮蜗杆减速器或者行星减速器，只要能够将水流驱动的转动机构2输出的动力转换为更大的输出扭矩即可，本申请对此不做具体限定。
示例性地，如图1及图3所示，减速机构3包括：动力轴301、第一减速齿轮302、第二减速齿轮303及输出轴304。该第一减速齿轮302具有与动力轴301啮合的大端面及用于与第二减速齿轮303啮合的小端面。动力轴301可以延伸至第一腔室1A内且连接转动机构2，由转动机构2带动。动力轴301与第一减速齿轮302的大端面配合，实现减速；第一减速齿轮302的小端面再与第二减速齿轮303配合，再次实现减速；第二减速齿轮303与输出轴304连接，如此，可以经过逐级减速后，将水流的动力经输出轴304传递给动力分配机构4。可以理解的是，设置于动力轴301与输出轴304之间的减速齿轮的数量可以根据需求进行设置，以满足减速比的需求。
在一些实施例中，如图4及图5所示，该减速机构3包括：动力轴301、 行星齿轮305、行星架306和齿圈307，其中，动力轴301连接转动机构2，并由转动机构2带动；齿圈307固定于外壳101上，可以理解的是，齿圈307可以为单独设置的环形件，且环形件的内壁设置内齿，该环形件固定于第三腔室1B内，或者在第三腔室1B的内壁上加工形成具有环形的内齿面的齿圈307；行星齿轮305布置于动力轴301与齿圈307之间，且与动力轴301及齿圈307均齿轮啮合；行星架306连接行星齿轮305，在行星齿轮305的驱动下输出动力给动力分配机构4。可以理解的是，动力轴301的一端可以延伸至第一腔室1A内且与转动机构2固定连接，动力轴301的另一端开设与行星齿轮305啮合的外齿，作为行星减速器的太阳轮。行星架306具有输出动力的端部，该端部连接动力分配机构4的输入端。
在一些实施例中，减速机构3的减速比为30～150:1。如此，该洗涤剂投放装置可以在0.03MPa～1.0MPa之间水压范围内正常工作，从而使得该洗涤剂投放装置具有广泛的应用前景，比如，可以应用于洗衣机或者洗碗机等家用电器中。
示例性地，前述的减速机构3、动力分配机构4及配给机构可以分别位于单独的腔室。如图1所示，配给机构设置于第二腔室1C内，外壳101内形成容纳减速机构3的第三腔室1B、容纳动力分配机构4的第四腔室1D，第三腔室1B及第四腔室1D位于第一腔室1A与第二腔室1C之间。
可以理解的是，前述的减速机构3、动力分配机构4及配给机构中的至少两个位于同一腔室。在一些实施例中，动力分配机构4可以设置于第三腔室1B内，即省去第四腔室1D，该第三腔室1B位于第一腔室1A与第二腔室1C之间，使得结构紧凑，且减速机构3、动力分配机构4均位于第三腔室1B内，使得洗涤剂投放装置外观美观。在一些实施例中，可以省去第三腔室1B和第四腔室1D，使得减速机构3及动力分配机构4均设置于第二腔室1C内。
如图6所示，动力分配机构4包括：主动轮401、第一棘轮轴402、从动轮403及第二棘轮轴404；其中，主动轮401连接减速机构3的输出端(如图3所示的输出轴304或者图4所示的行星架306)，主动轮401的内壁面设置第一棘齿4011；第一棘轮轴402套设于主动轮401内，且能与第一棘齿4011配合单向转动；从动轮403与主动轮401啮合连接，从动轮403的内壁面设置第二棘齿4031；第二棘轮轴404套设于从动轮403内，且能与第二棘齿4031配合单向转动。第一棘轮轴402形成动力分配机构4的第一输出端，第二棘轮轴404形成动力分配机构4的第二输出端。需要说明的是，主动轮401与从动轮403采用外齿啮合，二者的旋转方向相反，第一棘轮轴402与第二棘轮轴404单向转动的方向相同。比如，以第一棘轮轴402和第二棘轮轴404均顺时针单向转动为例进行说明，主动轮401顺时针转动时，第一棘轮轴402在第一棘齿4011的驱动下顺时针转动，从动轮403逆时针转动，第二棘轮轴404与第二棘齿4031打滑配合；主动轮逆时针转动时，第一棘轮轴402与第一棘齿4011打滑配合，从动轮403顺时针转动，第二棘轮轴404在第二棘齿4031的驱动下顺时针转动。
可以理解的是，主动轮401连接减速机构3的输出端，即连接图3所示的输出轴304或者图4所示的行星架306的端部，以在减速机构3传递的动力作用下转动。主动轮401与第一棘轮轴402构成第一棘轮组件，从动轮403与第二棘轮轴404构成第二棘轮组件，具体地，第一棘轮轴402的外壁面设置与第一棘齿4011配合的具有弹性的棘爪，通过棘爪与第一棘齿4011的配合，使得第一棘轮轴402只能单向旋转；同理，第二棘轮轴404的外壁面设置与第二棘齿4031配合的具有弹性的棘爪，通过棘爪与第二棘齿4031的配合，使得第二棘轮轴404只能单向旋转。由于主动轮401与从动轮403啮合连接，比如，通过齿或者销外啮合连接，使得主动轮401与从动轮403的转动方向相反。如图6所示，以棘轮轴与棘齿逆时针方向打 滑、顺时针方向转动为例进行说明，当主动轮401在减速机构3的带动下顺时针旋转时，从动轮403逆时针方向旋转，此时，第一棘轮轴402被主动轮401的第一棘齿4011推动也顺时针旋转，但第二棘轮轴404因从动轮403在逆时针转动，所以处于打滑状态，不传递扭矩。当主动轮401在减速机构3的带动下逆时针旋转时，从动轮403顺时针方向旋转，此时第一棘轮轴402处于打滑状态，不传递扭矩，但第二棘轮轴404因从动轮403顺时针旋转，在从动轮403的第二棘齿4031推动下，第二棘轮轴4042顺时针旋转，输出扭矩。如此，实现当输出轴304顺时针旋转时，动力被分配到第一棘轮轴402，当输出轴304逆时针旋转时，动力被分配到第二棘轮轴404。
在一些实施例中，第二腔室1C具有两个互相隔离的第一导流通道1014和第二导流通道1015，比如，可以在第二腔室1C内注塑形成两个互相隔离的第一导流通道1014和第二导流通道1015。示例性地，第一配给机构5为设置于第一导流通道1014内的泵体。可以理解的是，第一配给机构5可以是独立的泵体或者与第一导流通道1014的内壁面配合形成的泵体。示例性地，第二配给机构6为设置于第二导流通道1015内的泵体。可以理解的是，第二配给机构6可以是独立的泵体或者与第二导流通道1015的内壁面配合形成的泵体。
示例性地，如图1所示，壳体1还包括第二端盖103，第二端盖103与外壳101配合形成第二腔室1C。第二腔室1C具有第一进液口1016、第一出液口10117、第二进液口1018及第二出液口1019。对于第二腔室1C内形成互相隔离的第一导流通1014和第二导流通道1015的情形，如图7所示，第一导流通道1014具有第一进液口1016、第一出液口1017。第二导流通道1015具有第二进液口1018、第二出液口1019。
可以理解的是，当第一配给机构5和/或第二配给机构6为泵体时，泵 体的输入轴可以由第一棘轮轴402或者第二棘轮轴404驱动，进而实现洗涤剂的自动投放。这里，泵体可以为柱塞泵、叶片泵、隔膜泵、齿轮泵等，本申请对此不做具体限定。
在一些实施例中，如图7所示，第一棘轮轴402驱动第一配给机构5，第二棘轮轴404驱动第二配给机构6，第一配给机构5包括设置于第一导流通道1014内的第一齿轮501和第二齿轮502，第一齿轮501、第二齿轮502与第一导流通道1014的内壁配合形成齿轮泵，当第一棘轮轴402驱动第一齿轮501转动时，比如，如图7所示，第一棘轮轴402逆时针旋转时，第一齿轮501逆时针转动，与第一齿轮501啮合的第二齿轮502顺时针旋转，在第一齿轮501和第二齿轮502的配合下，洗涤剂经第一进液口1016进入，填充齿隙，再通过啮合挤出，从第一出液口1017流出，被配给到相应管路或容器中；第二配给机构6包括设置于第二导流通道1015内的第三齿轮601和第四齿轮602，第三齿轮601、第四齿轮602与第二导流通道1015的内壁配合形成齿轮泵，当第二棘轮轴404驱动第三齿轮601转动时，比如，如图7所示，第二棘轮轴404逆时针旋转时，第三齿轮601逆时针转动，与第三齿轮601啮合的第四齿轮602顺时针旋转，在第三齿轮601和第四齿轮602的配合下，洗涤剂经第二进液口1018进入，填充齿隙，再通过啮合挤出，从第二出液口1019流出，被配给到相应管路或容器中。
在一些实施例中，如图8及图9所示，第一配给机构5和/或第二配给机构6还可以为在外力驱动下往复位移的泵体。
如图9所示，第一配给机构5包括：第一泵壳体503、第一单向阀504、第二单向阀505及第一曲柄滑块机构507，其中，第一泵壳体503内形成第一泵内腔506，第一泵内腔506经第一单向阀504连通第一进液口1016，洗涤剂可以经第一进液口1016、第一单向阀504单向进入第一泵内腔506；第一泵内腔506经第二单向阀505连通第一出液口1017，第一泵内腔506 内的洗涤剂可以经第二单向阀505、第一出液口1017单向排出。第一曲柄滑块机构507可以在第一棘轮轴402的驱动下将周向运动转换为直线往复运动，从而使得与第一泵内腔506配合的滑块沿第一泵内腔506的内壁面往复位移，以驱动洗涤剂经第一进液口1016、第一单向阀504单向进入，并经第二单向阀505、第一出液口1017单向排出。其中，第一曲柄滑块机构507是指用曲柄和滑块来实现转动和移动相互转换的平面连杆机构，具体结构在此不再赘述。
如图9所示，第二配给机构6包括：第二泵壳体603、第三单向阀604、第四单向阀605及第二曲柄滑块机构607，其中，第二泵壳体603内形成第二泵内腔606，第二泵内腔606经第三单向阀604连通第二进液口1018，洗涤剂可以经第二进液口1018、第三单向阀604单向进入第二泵内腔606；第二泵内腔606经第四单向阀605连通第二出液口1019，第二泵内腔606内的洗涤剂可以经第四单向阀605、第二出液口1019单向排出。第二曲柄滑块机构607可以在第二棘轮轴404的驱动下将周向运动转换为直线往复运动，从而使得与第二泵内腔606配合的滑块沿第二泵内腔606的内壁面往复位移，以驱动洗涤剂经第二进液口1018、第三单向阀604单向进入，并经第四单向阀605、第二出液口1019单向排出。其中，第二曲柄滑块机构607是指用曲柄和滑块来实现转动和移动相互转换的平面连杆机构，具体结构在此不再赘述。
从以上的描述可以得知，本申请实施例洗涤剂投放装置工作过程中，水流经第一进水口1011流进第一腔室1A时，转动机构2顺时针转动；水流经第二进水口1012流第一腔室1A时，转动机构2逆时针转动；当控制第一进水口1011和第二进水口1012以相近的流量同时进水时，转动机构2正反转的动力互相抵消，保持不转动，但水流能正常经出水口1013流出。转动机构2的转动经减速机构3减速增扭后，将增大后的动力传递给动力 分配机构4；动力分配机构4将增大后的动力进行分配，分配后的一种动力形式经第一输出端分配给第一配给机构5，另一种动力形式经第二输出端分配给第二配给机构6。第一配给机构5控制第一进液口1016处洗涤剂的投放，第二配给机构6控制第二进液口1018处洗涤剂的投放，从而可以实现不同种类的洗涤剂的分类自动投放，且共用一个洗涤剂投放装置，从而可以进一步降低控制成本。

需要说明的是：本申请实施例所记载的技术方案之间，在不冲突的情况下，可以任意组合。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请 的保护范围应以所述权利要求的保护范围为准。
