本发明提供了一种洗碗机分层洗的控制方法，其中，如图4所示，洗碗机至少包括内胆，内胆内至少设有上下分布的多个搁架，每个搁架上都对应设有喷淋装置，每个喷淋装置通过各自的喷淋水路12相连通，并且多个喷淋水路12与水槽之间通过分水阀1相连通，分水阀1具有可旋转运动的分水片11，分水片11上设有多个通孔，当分水片11旋转，使得分水片11上的通孔与各个喷淋水路12导通或阻断，从而实现喷淋水路12的切换，其中，可以打开单个喷淋水路12，也可以打开多个喷淋水路12，本发明所述的分层洗是指在用户在一个搁架上放置餐具时，对应打开该搁架对应的喷淋水路12，从而实现节能减排。
如图1所示，洗碗机分层洗的控制方法具体包括以下步骤：
S101：确定盛放有待洗涤物的置物架；
S102：根据盛放有待洗涤物的置物架确定与其对应的第一喷淋水路；
S103：控制分水片11旋转至打开第一喷淋水路的位置，使得第一喷淋水路与供水装置连通且其他喷淋水路12关闭；
S104：执行预清洗步骤，使得喷淋水路12向盛放有待洗涤物的置物架喷淋。
在本发明中，首先控制器确定盛放有待洗涤物的置物架，进而确定与盛放有待洗涤物的置物架的第一喷淋水路，控制分水片11旋转至打开第一喷淋水路的位置，使得第一喷淋水路与水槽导通，且其他喷淋水路12与水槽阻断，在利用洗涤泵驱动洗涤水排入第一喷淋水路，实现对盛放有待洗涤物的置物架的喷淋，进而实现针对不同位置的餐具的分层洗涤，不但节约了水资源，且在使用过程中由于出水量不变，所以对出水的加热时间也无需增加，节约了洗涤时间的同时，减小了不必要的能耗。
其中的第一喷淋水路也可以理解为目标喷淋水路。
详细地，洗碗机的分层洗至少包括预清洗步骤、主洗步骤、漂洗步骤、干燥步骤等，增加预清洗步骤可以实现对餐具更好的清洗，在每次的洗涤任务中，控制器在执行预清洗步骤之前就控制分水片11旋转至打开第一喷淋水路的位置，并在之后的步骤中保持不变。
在一些实施例中，如图5和图6所示，设置转动件14与分水片11相连，驱动件通过驱动转动件14旋转同步带动分水片11旋转，转动件14上设有多个 触发件，详细地，多个触发件沿转动件14的周向间隔地设置，其中多个触发件与多个分水片11的旋转位置一一对应，例如洗碗机设有三个喷水装置和一一对应连通的三个喷淋水路12，其中喷淋水路12的打开方式共有六种，分别是单独开启三条喷淋水路12，或是两两开启喷淋水路12，则相应的触发件也设置有六个，每一个触发件对应一种喷淋水路12的打开方式，三个触发件对应三条喷淋水路12单独打开，其余三个触发件分别对应两条喷淋水路12的打开方式。
从而实现根据触发件的位置确定当前喷淋水路12的打开方式，具体地，如图2所示，所述的步骤S103具体包括：
S201：控制驱动件驱动转动件14旋转，转动件14旋转带动与之相连的分水片11以及转动件14上的多个触发件同步旋转，直到接收到与第一喷淋水路对应的触发件触发水路检测装置13发出的信号，控制驱动件暂停工作，使得分水片11的通孔与第一喷淋水路导通且与其他喷淋水路12阻断。
其中，多个触发件与多个分水片11的旋转位置一一对应，每个旋转位置对应一种水路切换方式。
在一个具体实施例中，可以设置每个触发件能够向水路检测装置13发射信号，例如，触发件能够向水路检测装置13发射红外线信号，水路检测装置13将接收到的信号反馈给控制器，控制器根据接收的信号实时判断当前转动件14的旋转位置，进而确定当前分水片11的旋转位置，直到收到与分水片11旋转至目标位置后控制驱动件暂停工作，使得分水片11保持在当前位置，实现目标水路与水槽导通。
在另一个具体实施例中，也可以设置转动件14上间隔地设有多个触发件，水路检测装置13包括与控制器连接的触点，当触发件旋转至对应触点的位置，触发件能够触碰触点，使得触点向控制器发出对应的信号。
进一步地，水路检测装置13包括与控制器连接的第一弹性触点和第二弹性触点，第一弹性触点和第二弹性触点之间间隔地设置，其中，所述的步骤S201具体包括：
转动件14旋转过程中多个触发件依次推动水路检测装置13的第一弹性触点，使得第一弹性触点和水路检测装置13的第二弹性触点接触并向控制器发出 相应的信号；
接收每个触发件触发水路检测装置发出的信号，直到接收到与第一喷淋水路对应的触发件推动第一弹性触点和第二弹性触点接触并发出相应的信号，控制驱动件暂停工作。
更进一步地，如图6和图7所示，本实施例中，水路检测装置13还包括连接件135、弹片136、转轴137、端子，其中连接件135包括能够导电的连接杆一和连接杆二，端子包括端子一131和端子二132，连接杆一的一端与端子一131连接另一端与弹片136连接，弹片136的另一端为自由端，连接杆二与端子二132连接，转轴137竖直设置，且转轴137和弹片136均具有弹性恢复量，其中，弹片136的另一端形成为第一弹性触点，连接杆二形成为第二弹性触点，转动件14带动凸块15转动并推动转轴137向弹片136方向发生形变，转轴137与弹片136接触并将弹片136推至与连接杆二连接，端子一131和端子二132之间通过弹片136连通，当转动件14带动凸块15继续转动时，压迫转轴137的凸块15逐渐与转轴137脱离，转轴137利用自身的弹性恢复至初始状态，同时弹片136失去了转轴137的压迫同样的回复初始状态，转动件14为圆盘状，端子一131、端子二132、端子三133和端子四134顺着转动件14的转动方向依次并排设置，将端子一131和端子二132之间连通，形成高电位后，控制器接收到连通信号控制对应水路开启，即可完成水路的选择，当选定水路后，驱动电机便停止转动，转动件14也相应的停止转动，凸块15依然挤压着转轴137，使得转轴137压迫弹片136将端子一131和端子二132一直保持导通的状态，直至洗碗机清洗完毕，通过转动件14的转动即可对水路进行选择，十分便捷。
具体的，端子还包括端子三133和端子四134，端子三133和端子四134之间一直为通路且为驱动电机的输出端口。
在一些实施例中，多个触发件中的一个触发水路检测装置13发出第一信号，其他触发件触发水路检测装置13发出第二信号，所述的步骤S201还包括：
判断接收的信号是否为第一信号；
若是，则判定当前推动第一弹性触点的触发件为初始位置的触发件，且当前分水片11位于初始位置；
否则，以接收的第一信号为基准，根据之后接收的第二信号的次序确定当前推动第一弹性触点的触发件，进而确定当前分水片11的旋转位置，其中，接收的第二信号的次序与其他触发件相对于初始位置的触发件的次序相对应。
详细地，设置触发件为凸块15，多个凸块15包括一个长凸块151和多个长度相同的短凸块152，且凸块15的外缘具有弧度，凸块15的外缘设置为弧形，保证随着转动件14的转动，凸块15能够以较大的面积挤压转轴137，即使设置水路组合方式较多需要许多凸块15的情况下，也可以在每个凸块15之间设置有间隙，保证水路选择的准确性，多个凸块15之间等距设置，长凸块151与短凸块152的区别仅仅是长度不同，当长凸块151转动至端子一131和端子二132的位置时，由于长凸块151的长度较长，所以端子一131和端子二132的连通时间也是最长的，通过端子一131和端子二132的连通时间，确定是长凸块151挤压着转轴137，转轴137压迫弹片136将端子一131和端子二132一直保持导通的状态，并设定此时的水路为初始位置，当判定完毕初始位置后，由于驱动电机带动转动件14为匀速转动，凸块15位置固定，所以只需要确定与下一个短凸块152将端子一131和端子二132之间导通与长凸块151将端子一131和端子二132之间导通的时间间隔，也就确定了由初始位置切换至下一种水路组合方式的时间，且由于凸块15之间为等距设置，所以确定了一个间隔时间就可以确认切换至下一个水路组合方式的时间，将这一信息记录至控制器，在使用过程中用户设定好需要使用的水路后，驱动电机带动转动件14转动，先找到设定的初始位置，也就是长凸块151挤压着转轴137，转轴137压迫弹片136将端子一131和端子二132一直保持导通的状态，随着转动件14的转动，对应第一喷淋水路的凸块15挤压转轴137并使得端子一131和端子二132导通时，驱动电机停止工作。
较佳的，所述第一信号为高电平信号，所述第二信号为低电平信号。
在一些实施例中，所述的确定盛放有待洗涤物的置物架具体包括以下步骤：
接收洗涤指令，所述洗涤指令包括置物架设定选项；
根据置物架设定选项确定盛放有待洗涤物的置物架。
本实施例通过用户在选择洗涤程序时直接由用户选择相应地需要单独洗涤的搁架，如洗碗机的触控面板上设有“上层洗”、“下层洗”的选择按键，这 样控制更简单。
在另一些实施例中，所述的确定盛放有待洗涤物的置物架具体包括以下步骤：
获取每个置物架的重量或压力，并根据每个置物架的重量或压力确定盛放有待洗涤物的置物架。

在本实施例中，用户可以自行设置需要洗涤的搁架以及具体的洗涤参数，使用体验更好。
进一步地，所述洗涤程序设定选项至少包括水流强度设定选项、主洗涤步骤时长设定选项。
在一些实施例中，在所述的控制洗碗机执行预洗涤步骤之前，还包括控制排水装置排出滞留水的步骤。
通过在每次洗涤之前先将洗碗机内的滞留水排出，避免污水污染餐具，保证洗涤效果。
本发明还提供一种洗碗机，包括控制器，所述控制器适于执行上述任一项实施例所述的洗碗机分层洗的控制方法。
一个具体实施例
本发明提供了一种洗碗机分层洗的洗涤方法，洗碗机设有分水阀1，安装在洗碗机的水槽底部电机出水口位置，通过切换分水片11位置来变换水路，将电机转动带动的水引入不同水路中，实现分层洗的功能。电动分水阀1中带有位置检测，通过位置判断告诉上位机现在所处的位置。
其中，分层洗的洗涤流程整体分为预洗涤步骤-主洗涤步骤-漂洗步骤-干燥 步骤四个阶段，具体分布流程如下：
如图3所示，预洗涤步骤具体包括以下步骤：
S301：执行排水程序；
S302：执行进水程序；
S303：流量计、浊度传感器判断进水是否正常；
若是，则执行步骤S304：继续执行进水程序；
S305：根据用户设定位置转动分水阀1，开始洗涤。
洗碗机先执行排水程序防止上次水未排干净，然后执行进水冲洗程序，通过流量计和浊度传感器进行进水判断，进水结束后根据用户设定的分层位置转动分水阀1，水通过洗涤泵带旋转喷淋臂工作，冲洗餐具，冲刷一段时间后执行排水程序，预冲洗阶段结束。
主洗涤步骤：洗碗机可以手动设置主洗时间，用户根据餐具的脏污程度可手动增加主洗时间，还可以通过改变电机转速，手动设置水流强度，包含超强，强力，标准(默认)，轻柔几个等级。主洗完成后海鲜已经清洗较为干净。
漂洗阶段：经过主洗餐具基本清洗干净，需要最后冲洗，投放光亮剂，增强洗涤和干燥的效果，洗涤阶段即结束。
干燥阶段：洗涤阶段结束后，风机开始工作，保证洗碗机容腔的干燥率，达到好的用户体验效果。
以上仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
