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。
结合图1至图4，本发明提供了一种分流器100，分流器100包括阀体10和挡件50，其中阀体10具有流道20、入口30和多个出口40，入口30和多个出口40均与流道20连通，且多个出口40沿流道20排布。挡件50可移动的设于阀体10的流道20内，其中流道20引导从入口30进入的流体沿预定方向流通，也就是说，流体在进入到流道20内后，大部分或全部的流体将会在流道20的引导下沿预定方向流通，其中预定方向为与流道20的延伸方向平行的单方向。流道20在引导流体流通的过程中，将会驱动挡件50沿预定方向移动，使挡件50可以封堵多个出口40中的一个，且挡件50适于由流体驱动以切换挡件50封堵的出口40。
该分流器100在使用过程中，流体可以由入口30进入流道20，流道20引导流体沿预定方向流通，挡件50在流体驱动下运动到与多个出口40中的一个相对的位置，并适于封堵该出口40，则流体从未封堵的出口40流出。另外，在流体的驱动作用下，挡件50可以切换其封堵的出口40，例如，流体在不同的时机、方式或驱动力等进入流道20时，可以驱动挡件50封堵不同的出口40，从而实现改变分流器100的分流方向、 分流流路等的目的。
根据本发明实施例的分流器100，通过在分流器100内设有流道20，流道20引导从入口30进入的流体沿预定的方向流通，并通过流体驱动挡件50封堵不同的出口40，实现流体从不同位置流出，以实现分流的功能。另外，本发明中利用流道20引导流体流通，并通过流体对挡件50进行驱动，简化了分流器100的结构，并采用机械的方式对挡件50进行驱动，使分流器100的控制简单、故障率低，优化了分流器100的稳定性和可靠性，并降低了成本。
其中，本发明中的挡件50可以为一个，例如，当存在两个出口40时，可以利用该挡件50封堵两个出口40中的一个，并使流体从另一个出口40流出。另外，当存在三个以上的出口40时，可以利用挡件50对其中的一个或两个出口40进行封堵，其中，本发明中的挡件50可以为多个，多个挡件50可以设为一体，以实现流体从不同出口40流出，丰富分流器100的分流模式。
结合图1至图3，在本发明的一些实施例中，流道20可以设置成环形(例如圆环、椭圆环、矩形环等)，其中，预定方向可以为流道20的顺时针方向或逆时针方向，流体可以沿逆时针方向沿流道20流通，多个出口40可以沿流道20排布，也就是说，多个出口40可以沿逆时针方向排布。其中，可以通过设置入口30沿流道20的切向延伸以方便水流沿预定的方向流通，也可以通过将流道20的首端设置成低于终端，以使流道20的首端和终端之间具有落差，而促使流体沿预定方向流通，当然，本发明中的流道20还可以为直线流道20、弧线流道20等，可以根据实际使用调整流道20的形状，本发明中并未对流道20的形状进行限定，上述描述仅仅是本发明的一些具体实施方式。
另外，需要说明的是，本发明中的分流器100主要适用于流体的分流，以便于从入口30进入到分流器100的流体可以选择性地从出口40流出。本发明的分流器100可以适用于对液体、气体等流体的分流，尤其适用于对水的分流。本发明中主要以对水分流为例进行说明，而且主要以该分流器100应用于洗碗机为例，但是这并非是对本发明保护范围的限制，本发明中的分流器100同样适用于其他流体，也同样适用于其他的使用环境。
本发明的分流器100的出口40可设在流道20的不同位置，例如出口40可以设于流道20的侧面，流体从入口30进入流道20，流道20引导流体流通，并驱动挡件50移动，封堵多个出口40中的一个，液体从未封堵的出口40流出，实现分流功能。
参照图1至图2，在本发明的一些实施例中，出口40可设于流道20的顶面上，多个出口40沿平行于流道20的预定方向间隔排布，挡件50适于上下方向移动以封堵和打开对应的出口40。流道20的底面可设有与出口40对应的下引导部60，下引导部60 可包括第一引导面61，第一引导面61沿预定方向朝向对应的出口40延伸，并在预定方向上与对应的出口40在高度方向上的距离逐渐缩小，以使挡件50沿预定方向移动时引导挡件50封堵对应的出口40。这样，当流体从入口30进入流道20，经过流道20的引导，沿预定方向流通，挡件50通过下引导部60的第一引导面61的引导，沿预定方向上逐渐上升，通过流道20对流体的引导以及流体驱动挡件50，使挡件50稳定的封堵出口40，提高对出口40的封堵效果，优化了分流器100的分流效果和稳定性。
其中，下引导部60还可包括第二引导面62，第二引导面62可与第一引导面61相连，并沿预定方向朝远离对应的出口40方向延伸，且在预定方向上与对应的出口40在高度方向上逐渐增大。挡件50在封堵出口40时脱离第二引导面62，这样，挡件50在失去流体驱动时，第二引导面62引导挡件50朝向另一出口40移动，避免挡件50封堵完出口40后沿第一引导面61返回，使挡件50可以在流道20内不断向前运动。
本发明中的分流器100可以应用于洗碗机或其他需要进行液体分流的设备中，在将该分流器100应用于洗碗机上时，可以根据洗涤泵的启停对挡件50的位置进行调整，以实现封堵不同的出口40的目的。
进一步地，参照图1和图5，下引导部60可包括第一引导面61和第二引导面62，第一引导面61与第二引导面62沿预定方向上延伸，第一引导面61在预定方向上与对应的出口40在高度方向上逐渐缩小，第二引导面62在预定方向上与对应的出口40在高度方向上的距离逐渐增加，第一引导面61和第二引导面62相接处有最高点，最高点可与对应的出口40正对，并位于对应的出口40的中心线的上游。当分流器100应用到洗碗机中时，当洗涤泵工作，水流从入口30进入流道20。水流经过流道20的引导，沿预定方向流通，通过设置下引导部60，使挡件50受到水流向前和向上的推力，沿第一引导面61逐渐上升，过最高点后脱离下引导部60到达对应出口40位置，挡件50封堵住出口40，则未封堵的出口40出水。当洗碗机的洗涤泵停止工作时，挡件50随重力作用沿第二引导面62运动至低位，当洗涤泵再次工作时，挡件50被驱动到下一个出口40。可避免洗涤泵停止工作后，挡件50原路返回。通过第一引导面61和第二引导面62的布置，以及第一引导面61和第二引导面62的相接处的最高点与对应的出口40相对，并位于对应出口40的中心线上游，使挡件50可以在流道20内沿预定方向运动，以达到挡件50可以按预定的方式运动封堵对应的出口40，提高分流器100工作过程中的稳定性。
参照图4，在上述实施例中，第一引导面61和第二引导面62相接处的最高点与对应的出口40沿高度方向上的距离可大于挡件50沿高度方向的尺寸，第一引导面61和第二引导面62的相接处的最高点与对应的出口40相对，并位于对应出口40的中心线 上游，也就是说出口40的位置相对于最高点向前偏移，这样在挡件50沿第一引导面61移动，过最高点后可以有效封堵住对应出口40，提高分流器100工作的稳定性。
本申请的第一引导面61和第二引导面62可以设置成不同的形式，例如第一引导面61的坡度可大于第二引导面62的坡度，或第一引导面61的坡度小于第二引导面62的坡度，或第一引导面61的坡度等于第二引导面62的坡度，可以根据分流器100实际使用的环境及分流器100内部的空间大小进行调整，以实现分流器100可以稳定、高效的工作。
举例而言，如图1，第一引导面61的坡度可以大于第二引导面62的坡度。洗涤泵工作，水流从入口30进入后，通过将第一引导面61的坡度设置成大于第二引导面62的坡度，挡件50受到水流沿入口30进水方向向前和向上的推力后，挡件50可以快速沿第一引导面61到达最高点，过最高点后到达出口40并封堵出口40，以提高挡件50封堵出口的效率，提升分流器的工作性能。当洗涤泵停止工作时，挡件50由于重力作用，可沿第二引导面62下落至流道20的底面。
第一引导面61的坡度也可以小于或等于第二引导面62的坡度，可根据分流器100内的空间的大小，调整第一引导面61与第二引导面62的坡度与长度。例如，第一引导面61的坡度可以小于第二引导面62的坡度，同时，第一引导面61的长度可大于第二引导面62的长度，洗涤泵工作，水流从入口30进入后，挡件50受到水流沿入口30进水方向向前和向上的推力后，挡件50可以稳定地沿第一引导面61到达最高点，过最高点后到达出口40并封堵出口40，当洗涤泵停止工作时，挡件50由于重力作用，可沿第二引导面62快速下落至流道20的底面。可以理解地是，第一引导面61的坡度可等于第二引导面62的坡度，同时，第一引导面61的长度可等于第二引导面62的长度。
参照图1，在本发明的一些实施例中，多个出口40可设于流道20的顶面上，沿预定方向排布，在流道20底面上可设有多个与出口40相对应的下引导部60。在驱动挡件50的过程中，挡件50将会沿着预定方向移动，同时，在下引导部60的引导作用下上升至预定的位置，以封堵对应的出口40，促使流体从其他出口40流出。当失去流体驱动时，下引导部60引导挡件50朝向另一出口40移动。通过设置与出口40对应的下引导部60，可以对挡件50在流道20内的移动方向进行引导，使挡件50在流道20内沿预定方向运动，以封堵和打开对应的出口40，达到稳定出水的目的。
参照图1和图3，在本发明的一些实施例中，下引导部60可被构造成沿流道20的宽度方向间隔排布的多轨道结构，例如，下引导部60可以包括多个第一轨道63，多个第一轨道63沿流道20的宽度方向间隔排布。从而实现挡件50稳定在下引导部60上 运动，以封堵和打开出口40，避免挡件50运动过程中滑落，使分流器100性能稳定，故障率低，其中，多轨道结构优选为双轨道，也就是说，下引导部60可包括两个第一轨道63，挡件50可以是球体，以实现挡件50可稳地在轨道上运动。
通过设置多轨道结构，能够方便流体流过下引导部60，避免了下引导部60对流体的阻挡作用，降低流阻，优化分流器100的性能。
参照图1和图6，在本发明的一些实施例中，流道20的顶面上可设有与出口40对应的上引导部70，上引导部70可包括第三引导面71，在流道20的底面上可设有下引导部60，下引导部60包括第一引导面61与第二引导面62，第三引导面71与第一引导面61相对，且沿预定方向相对于流道20的顶面的高度逐渐降低，第三引导面71的末端连接至对应的出口40。在洗碗机中，当洗涤泵工作时，水流从入口30进入后，流道20引导水流流通，挡件50受到水流沿入口30进水方向向前和向上的推力，沿第一引导面61逐渐上升脱离，并与上引导部70接触，到达对应出口40位置，封堵住出口40，未封堵的出口40出水，当洗涤泵停止工作时，挡件50随重力作用沿第二引导面62下落至流道20的底面。通过第一引导面61和第三引导面71相配合，挡件50可以沿流道20稳定的封堵对应的出口40，当洗涤泵停止工作时，挡件50沿第二引导面62下落至流道20的底面，提高了分流器100工作过程中的稳定性。
参照图6，其中，上引导部70可被构造成沿流道20的宽度方向性间隔排布的多轨道结构，例如，上引导部70可以包括多个第二轨道72，多个第二轨道72沿流道20的宽度方向间隔排布。这样，挡件50沿第一引导面61逐渐升高，与上引导部70接触后，可稳定的在多个第二轨道72上运动到出口40，以封堵出口40，避免挡件50在运动过程中滑落，使分流器100的性能稳定，故障率低。其中，多轨道结构优选为双轨道，也就是说上引导部70可包括两个第二轨道72，挡件50可以是球体，通过设置两个第二轨道72，可使挡件50稳定地沿上引导部70运动，提升分流器100工作的稳定性。
其中，本发明中的挡件50可以设置成浮在液体表面上的结构，也就是说，在流道20内的液体水位上升时，挡件50可以随着液体水位的上升而升高、随着液体水位的下降而下落。例如，在洗碗机中，当洗涤泵工作时，水流进入入口30，挡件50沿流道20方向向上运动，封堵出口40，当洗碗机洗涤泵停止工作时，挡件50由于重力作用，向下运动。当然，本发明中的挡件50的平均密度也可以大于液体的密度，并利用流体的压力和推动力维持挡件50封堵出口40的状态。
如图1，在本发明的一些实施例中，流道20被构造成环形流道20结构，入口30被构造成适于沿流道20的环绕方向进水，以驱动挡件50沿流道20移动。流体从入口 30进入到流道20内后，会沿着流道20的预定方向流通，同时，流体会驱动挡件50移动到预定的位置以封堵对应的出口40，以达到沿指定流路出水。简化了分流器100的结构，通过设置流道20，引导液体流通，便于利用流体驱动挡件50，同时，挡件50可以沿着流道20的预定方向移动，可以方便挡件50对多个出口40进行开闭，便于对液体流通方向进行旋转和调整。
其中，入口30的轴线可偏离流道20的中心。因此，流体从入口30进入到流道20内时，将会沿着预定的方向流通，可以便于限制流体的流通方向，另外，入口30的轴线可以设置成沿流道20的切向延伸的形式。
在上述实施例中，所述分流器100的挡件50可以是球形，出口40可以为径向尺寸小于挡件50的圆孔。从而实现挡件50运动到出口40后，可以与出口40更好的配合，以封堵出口40，防止封堵出水后有漏水现象。
参照图1，在本发明的一些实施例中，阀体10可以包括阀座12和阀盖11，阀盖11可封盖阀座12，构造成流道20。可在阀座12的周壁上设有凸台111，阀盖11的周缘上设有凹槽121，凸台111嵌入凹槽121内，定位阀座12和阀盖11；也可以在阀座12的周壁上设有凹槽121，在阀盖11的周缘上设有凸台111，凸台111嵌入凹槽121内，定位阀座12和阀盖11；其中，凸台111的数量可以是一个或多个，凹槽121的数量也可以是一个或多个，凸台111与凹槽121的数量相对应。通过设置阀座12和阀盖11，并通过凸台111与凹槽121的装配，使分流器100的流道20结构更稳固，且凸台111与凹槽121的连接，简化装配程序。
在本发明的一些实施例中，分流器还可包括位置检测件80，位置检测件80可以检测挡件50的位置，例如挡件50在封堵不同出口40时的位置，或者挡件50未封堵出口40时可触发对应的位置检测件80，从而实现改变分流器100的分流方向、分流流路等的目的，使分流器100的控制简单、故障率低，优化了分流器100的稳定性和可靠性，并降低了成本。
具体而言，通过位置检测件80检测挡件的位置，当挡件50运动到预定位置后，位置检测件80生成位置信号并将信号传输到洗碗机1000的电控软件中，电控软件可记录此时挡件的位置，进而计算控制洗涤泵启停来控制挡件50运动到指定出口，实现控制不同出口出水的目的。
参照图7，在本发明的一些实施例中，位置检测件80可以位于阀体10的外部，当位置检测件80位于阀体10的外部时，在挡件50封堵出口40时或者在挡件50未封堵出口40时，触发位置检测件80。位置检测件80也可以嵌入到阀体10内，可在多个出口40中的至少一个对应位置设有位置检测件80，这样，在挡件50封堵出口40时时可 触发对应的位置检测件80，使位置检测件80高效的检测到挡件50的位置，从而保证分流器100的工作更稳定。
其中，位置检测件80可被构造成在挡件50封堵出口40时被触发。例如，位置检测件80可设于阀体10外，位置检测件80为磁性传感器，挡件50可以整体是磁性感应部，可根据磁感应强度感应挡件50的位置，当挡件50封堵出口40时，磁性传感器被触发，并生成位置信号。位置检测件80也可以设于阀体10内，例如可以设置在出口40处，位置检测件80为磁性传感器，挡件50上嵌设有磁性感应部，当挡件50封堵出口40时，磁性传感器被触发，并生成位置信号。当位置检测件80设于阀体10内时，可以在每个出口40的对应位置设有位置检测件80，也可以在多个出口40中的至少一个出口40的对应位置设有位置检测件80。
可以理解的是，位置检测件80也可被构造成挡件50未封堵出口40时被触发。例如，位置检测件80设于阀体10外，当挡件50未封堵出水口，处于阀体10的低位时，根据磁感应强度感应到挡件50的位置，磁性传感器被触发，并生成位置信号。可以理解的是，位置检测件80也可以设于阀体10内，可根据不同的磁感应强度，计算挡件50的位置信息，并生成位置信号。
进一步地，挡件50可以包括具有导磁性或磁性的感应部，位置检测件80可以是磁性传感器，通过位置检测件80可以准确的检测到挡件50的位置。
其中，挡件50的感应部可以有多种形式，挡件50可以整体构造成感应部，或者挡件50的部分为感应部，感应部可嵌设于挡件50上，感应部可层叠于挡件50上，感应部可构造成挡件50上的涂层。例如挡件50材质可以是铁、钴、镍、金属合金或者磁铁等，挡件50可以整体上是由导磁性或磁性的材质构成，也可以是由部分导磁性或磁性的材质构成，位置检测件80是磁性传感器，可以感应到挡件50的位置。挡件50可以不受形状、材质或使用环境等的限制，灵活设置感应部的形式，使位置检测件80有效的检测到挡件50的位置。也可以根据不同的使用环境来调整挡件50的感应部形式，以达到位置检测件80可以准确的检测到挡件50的位置的效果。
具体而言，当分流器100应用于洗碗机上时，可以根据洗涤泵的启停对挡件50的位置进行调整，以实现封堵不同的出口40的目的。例如，静止状态时，挡件50由于重力作用处于流道20的低位，洗碗机的洗涤泵工作时，水流从入口30进入流道20，沿流道20的延伸方向流通，挡件50在受到水流向前和向上的推力，沿着下引导部60的第一引导面61上升脱离，挡件50被引导进出口40位置，封堵出口40，则未封堵的出口40出水，位置检测件80可感应到挡件50的位置，并将位置信息生成感应信号，位置检测件80将感应信息号反馈到洗碗机的电控软件中，电控软件记录此时挡件50 的位置信息，通过计算控制洗涤泵启停，使挡件50运动到封堵指定的出口40，实现控制不同位置出水的目的，优化了分流器100的分水效果和稳定性。
在本发明的一些实施例中，分流器还可包括光耦传感器90，光耦传感器90可用于检测挡件50的位置，检测到挡件50位于指定位置时，将位置信息生成感应信号，从而实现改变分流器100的分流方向、分流流路等的目的。
在本发明的一些实施例中，光耦传感器90可以被构造成在挡件50封堵出口40时被触发，光耦传感器90可用于发射和接收光源。当流体从入口30进入流道20，驱动挡件50沿预定的方向移动封堵住出口40，光源被阻断，光耦传感器90生成位置信号，从而实现改变分流器100的分流方向、分流流路等的目的。
其中，光耦传感器90可以包括多个，多个光耦传感器90与出口40相对应，这样，可以在挡件50封堵出口40时，准确的检测到挡件50的位置，并生成信号，提高光耦传感器90检测的精确度，进而提升分流器100工作的稳定性。
参照图8，其中，挡件50位于流道20底面时可触发光耦传感器90，光耦传感器90可用于发射和接收光源。例如在洗碗机中，当洗涤泵工作时，水流从入口30进入，挡件50受到水流向前和向上的推力，沿着下引导部60上升，封堵出口40，当洗涤泵停止工作时，挡件50因为重力作用下落至流道20的底面，光源被阻断，光耦传感器90生成位置信号，并将位置信号反馈到洗碗机的电控软件中，软件记录此时挡件50的位置，通过计算控制洗涤泵启停的风湿，使挡件50运动到指定的出口40，从而实现控制不同出口40出水的目的。
参照图9，在本发明的一些实施例中，分流器100的出口40位置或者流道20的底面可设有安装孔91，光耦传感器90可设于安装孔91内，光耦传感器90固定在安装孔91内，以更好的实现对挡件50的位置检测，从而实现控制不同出口40出水的目的。
根据本发明实施例的洗碗机，可以采用前述的分流器100结构，可以利用水流选择性地切换出口40，以进行分流，满足洗碗机的不同洗涤需求，优化了洗碗机的性能，使得洗碗机可以方便实现不同的洗涤模式。
参照图10，其中，洗碗机1000还可包括内胆200、洗涤泵300和多个喷臂400，洗涤泵300与分流器100连接，以驱动水流流向分流器100。喷臂400的数量可以与出口40的数量对应，喷臂400与出口40连通，水流可从出口40流到对应的喷臂400，水从喷臂400喷出，以进行洗涤工作。分流器100可设于内胆200的下方，分流器100连接洗涤泵300与喷臂400，当洗碗机1000工作时，洗涤泵300驱动水流从入口30进入到分流器100中，挡件50在水流的驱动下，选择性地切换封堵出口40，水流从未封堵的出口40流出到对应的喷臂400，完成洗涤的工作。可通过控制洗涤泵300的启 停，使挡件50运动到指定的出口40，实现不同的喷臂400出水的目的。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
