Description

添加剂投放装置的控制方法、控制模块及添加剂投放装置 技术领域
本发明属于洗涤设备技术领域，具体地说，涉及一种添加剂投放装置的控制方法、控制模块及添加剂投放装置。
背景技术
在使用洗涤设备进行衣物的清洗时，需要投入洗涤剂、柔顺剂等添加剂，以达到更好的洗衣效果。添加剂可由用户手动添加，或者由自动投放装置进行自动添加。用户手动投入添加剂时，无法实现对添加剂投放量的精确控制，投放量若偏少会影响洗衣效果，投放量偏大时会造成添加剂的浪费。目前的自动投放装置大多集成在洗涤设备内部，受洗涤设备整机尺寸的限制，自动投放装置的尺寸有限，添加剂的最大储量偏小，需要用户频繁补充，使用不便。
为解决上述问题，现有技术提出了一种独立于洗涤设备的投放装置，由于投放装置独立设置，其添加剂储量不再受洗涤设备整机体积的限制。但在上述方案中，由于投放装置和洗涤设备分别具有独立的控制系统，投放装置无法直接获取洗涤设备的运行状态，进而无法判断何时进行添加剂的投放。
一种解决方案是由用户自主判断洗涤设备的运行阶段，并在需要投放添加剂时操作投放装置实现投放。但由于需要用户的介入，操作较为繁琐，使投放装置的自动化程度大打折扣，不便于用户使用。另一种解决方案是在投放装置与洗涤设备各自的控制系统之间建立通讯连接，以实现投放装置对洗涤设备运行进程的获取。但上述方案要求洗涤设备具有通讯功能，增加了洗涤设备的制造成本，同时，无法应用于非联网型洗涤设备。
目前为实现投放装置与洗涤设备之间无通讯情况下的自动投放，提出了在投放装置上设置流量计，通过流量计检测洗涤设备的进水情况以进行投放的方案。但流量计仅能判断洗涤设备是否正在进水，而无法直接判断当前进水过程是属于洗涤阶段还是漂洗阶段，当投放装置用于投放洗涤剂时，很容易出现误判而在漂洗进水阶段向洗涤设备中投入洗涤剂，影响洗衣效果。
另一方面，随着人们生活水平的提高，对洗衣、护衣的效果体验逐渐细化，越来越多的家庭拥有两台及以上洗护设备，以分别满足不同的衣物洗护效果，其中，洗护设备例如洗衣机、干衣机等是家庭普遍使用的家用电器，而各式各样的洗护设备给人们的生活带来了诸多方便。
在衣物洗护过程，需要将洗涤剂、柔顺剂、添香剂、漂白剂、消毒剂等用于衣物洗护的添加剂中的任一或多种组合作用于衣物上，以达到对衣物进行洗护、增香、消毒等的效果，实现更细致地洗衣、护衣。
而洗衣房洗护场景或者智慧阳台洗护场景中，存在多台洗护设备同时或先后被使用的情况，如何实现更加精确、智能地控制添加剂投放装置依次向各洗护设备投放添加剂，成为亟 待解决的问题。
有鉴于此，特提出本发明。

和/或，存储基于各洗护设备的配置信息确定的添加剂投放装置向各洗护设备投放添加剂的优先级，所述配置信息包括洗护设备类型、容量值、允许执行的洗护程序和所述洗护程序对应的标准投放参数。
进一步，按照优先向波轮洗衣机或滚筒洗衣机投放添加剂确定添加剂投放装置向各洗护设备投放添加剂的优先级；
和/或,按照各洗护设备的容量值由小到大的顺序确定添加剂投放装置向各洗护设备投放添加剂的优先级；
和/或,按照执行的洗护程序为主洗护程序或附加洗护程序优先投放添加剂确定添加剂投放装置向各洗护设备投放添加剂的优先级；
和/或,按照各洗护设备允许投放的洗护程序对应标准投放参数由小到大的顺序确定添加剂投放装置向各洗护设备投放添加剂的优先级。
进一步，所述基于关联的洗护设备的运行状态和/或关联关系包括：
基于关联的洗护设备的运行状态，确定各洗护设备的洗护程序；
若存在多台洗护设备同步执行洗护程序时，则基于关联的洗护设备的运行状态和/或关联关系确定各洗护设备的投放顺序。
进一步，若存在多台洗护设备同步执行相同洗护程序时，则基于关联关系确定各洗护设备的投放顺序；
若存在多台洗护设备同步执行不同洗护程序时，则基于洗护程序确定各洗护设备的投放数据，并基于投放数据确定向各洗护设备投放添加剂的投放顺序，所述投放数据包括添加剂类型、投放量和投放时间。
进一步，按照执行的洗护程序为主洗护程序优先或附加洗护程序优先确定依次向各洗护设备投放添加剂；

和/或,按照投放时间由短到长的顺序依次向各洗护设备投放添加剂。
进一步，所述基于关联的洗护设备的运行状态和/或关联关系包括：
基于关联的洗护设备的运行状态，确定各洗护设备的洗护程序；
若存在多台洗护设备先后执行洗护程序时，则基于执行洗护程序由先到后的顺序依次向各洗护设备投放添加剂。
本发明还提供了一种采用上述任一所述的控制方法的添加剂投放装置控制模块，包括：
存储单元，用于存储添加剂投放装置与多台洗护设备的关联关系；
通信单元，用于获取与添加剂投放装置关联的洗护设备的运行状态；
生成单元，分别与存储单元和通信单元连接，用于接收存储单元存储的添加剂投放装置与各洗护设备的关联关系和通信单元获取的关联的洗护设备的运行状态，并基于运行状态和/或关联关系确定各洗护设备的投放顺序。
本发明还提供了一种添加剂投放装置，采用上述任一所述的控制方法，和/或，具有上述所述的添加剂投放装置控制模块。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明中，添加剂投放装置可以根据前次进水与本次进水之间的时间间隔ΔT控制本次进水过程中是否进行添加剂的投放，在添加剂投放装置与洗涤设备之间不建立通讯连接的情况下，也可以有效避免添加剂的误投放。
本发明中，添加剂投放装置时间间隔ΔT较小的情况下不进行添加剂投放，当洗涤设备运行一次完整的洗衣程序时，防止出现例如在漂洗进水阶段再次投放洗涤剂的误投情况。在时间间隔ΔT足够大时，无需用户再次操作，添加剂投放装置能够自行判断进行添加剂投放， 自动化程度高，使用方便。添加剂投放装置在检测到持续进水达到时间阈值t 0时才进行投放，避免了其在喷淋进水阶段或偏心均布进水阶段误投洗涤剂的情况。
本发明中，添加剂投放装置在进水过程中间歇投放添加剂，使添加剂在进水过程中均匀分布在水中，进而在后续洗衣过程中更容易在水中均匀分散，充分溶解，以达到更好的洗衣效果。同时，每间隔固定的进水时长时投放固定量的添加剂，使添加剂的投放量与已进水时长始终保持在一定比例，添加剂投放装置无需预先获知总进水时长，也可以实现对添加剂投放量的准确控制。
本发明中，添加剂投放装置在第一次执行第一投放步骤前，先执行第二预设投放量S 2的第二投放步骤，第二预设投放量S 2对应时间阈值t 0内的进水量，使总投放量更加精确。同时，由于t 0>T 0，可以保证添加剂投放装置在本次进水过程中进行第一次添加剂投放时，洗涤设备内已经有足够量的水，避免添加剂直接被衣物吸收，无法充分溶解在水中，影响洗衣效果。
本发明中，添加剂投放装置在接收到手动投放指令后，在水流检测模块检测到进水后就会进行添加剂投放，而不再根据时间间隔ΔT判断是否进行投放，可以满足用户特殊情况下的洗衣需求，例如需连续运行两次或更多次洗涤程序时，也可以进行连续多次的添加剂投放。
本发明中，添加剂投放装置可以与多台洗护设备相关联，基于每台洗护设备的运行状态和/或与添加剂投放装置的关联关系，控制添加剂投放装置自动向不同的洗护设备依次投放添加剂，使各洗护设备具备自动投放功能，无需用户手动触发添加剂投放装置，提升用户使用体验。

实施例一
本实施例提供一种添加剂投放装置及其控制方法，所述添加剂投放装置用于例如洗衣机等洗涤设备，可以实现添加剂的自动投放。
如图1所示，本实施例中的添加剂投放装置包括与外接水源连接的进水端8，与洗涤设备连接的出水端9，以及设置在进水端与出水端之间的水流检测模块。具体地，所述添加剂投放装置包括进水管路、投放管路，以及用于盛放添加剂的储液腔。所述进水管路的两端分别连接添加剂投放装置的进水端8和出水端9，所述水流检测模块设置在进水管路上。所述投放管路两端分别连通储液腔与进水管路，投放管路上设置投放机构，如抽液泵，用于向进水管路中投放添加剂。
使用时，将添加剂投放装置的进水端8与外接水源连接，出水端9连接至洗涤设备的进水口。洗涤设备进水时，洗涤设备的进水阀打开，外接水源经过添加剂投放装置的进水管路，进而从洗涤设备的进水阀进入洗涤设备中。需要进行添加剂投放时，投放机构将储液腔中的添加剂投放至进水管路中，使添加剂随着进水管路中的进水一同进入洗涤设备中。
本实施例中，所述水流检测模块可以为检测水流量的流量传感器，洗涤设备进水时，进水管路中产生流动的水流经过流量传感器，根据流量传感器是否检测到水流通过即可判断洗涤设备是否正在进水。
本实施例的另一种方案中，所述水流检测模块为检测进水管路水静压的压力传感器，所述压力传感器的测量管口位于进水管路的内壁面，洗涤设备进水时，进水管路中的水流动， 压力传感器检测到的压力减小，洗涤设备停止时，进水管路中的水静止，检测到的压力增加至外接水源供水压力。根据压力传感器检测到压力大小即可判断洗涤设备是否正在进水。
本实施例中，添加剂投放装置上还设置用于向储液腔中加入添加剂的添加剂投入口1，以及可供用户观察储液腔中添加剂剩余量的透明显示窗2。用户可通过透明显示窗2及时发现添加剂不足的情况，然后经添加剂投入口1向储液腔中补充添加剂，保证添加剂投放装置在使用时具有足量的添加剂用于投放。
本实施例中，所述添加剂投放装置还包括计时模块，所述计时模块可在添加剂投放装置的工作过程中进行计时，从而获取前次进水与本次进水之间的时间间隔ΔT。
本实施例中，添加剂投放装置用于在洗涤设备的洗涤进水阶段进行洗涤剂的投放。如图2所示，所述添加剂投放装置的控制方法包括：添加剂投放装置根据前次进水和本次进水之间的时间间隔ΔT控制是否进行添加剂投放。
为实现上述控制方法，本实施例的添加剂投放装置还包括处理模块。添加剂投放装置的工作过程中，水流检测模块用于检测是否正在进水，计时模块用于获取前次进水和本次进水之间的时间间隔ΔT并反馈至处理模块。处理模块用于根据时间间隔ΔT判断是否控制投放模块执行添加剂投放操作，并在需要进行投放时向投放模块发送指令，由投放模块执行添加剂投放操作。
本实施例中，所述投放模块即为设置在投放管路上的投放机构。
具体地，若所述时间间隔ΔT小于预设时间间隔ΔT 0，添加剂投放装置在洗涤设备本次进水过程中不进行添加剂投放。
若所述时间间隔ΔT大于等于预设时间间隔ΔT 0，在水流检测模块检测到持续进水时长达到时间阈值t 0后，添加剂投放装置在本次进水的后续进水过程中进行添加剂投放。
本实施例的一种方案中，所述的前次进水为本次进水之前最接近的一次进水。所述时间间隔ΔT具体为本次进水前最接近的一次进水结束与本次进水开始之间的间隔时间。
上述方案中，水流检测模块每次检测到进水停止时，计时模块即开始计时，然后在水流检测模块再次检测到开始进水时可以获取所述时间间隔ΔT并进行反馈，用于判断本次进水是否进行添加剂投放，控制逻辑简单。
一般的洗涤设备运行一次完整的洗衣程序，会先后经过洗涤进水阶段及至少一次漂洗进水阶段。洗涤进水阶段需添加剂投放装置进行洗涤剂投放，漂洗进水阶段不进行投放。
本实施例中，所述预设时间间隔ΔT 0大于等于洗涤设备运行一次洗衣程序所需的最长时间。优选将预设时间间隔ΔT 0设置为等于洗涤设备运行一次洗衣程序所需的最长时间，如2～5小时。只有在两次相邻的进水之间的间隔时间大于预设时间间隔ΔT 0时，添加剂投放装置才会进行添加剂投放，可以实现添加剂投放装置在一次完整的洗衣程序中，在洗涤进水阶段自动进行投放，在漂洗进水阶段不进行投放的目的。
在用户在短时间内运行两次洗衣程序时，可能出现第二次洗衣程序的洗涤进水阶段与前次洗衣程序的漂洗进水阶段之间的间隔时间较短，出现不需要投放洗涤剂的误判。
针对上述情况，本实施例中的预设时间间隔ΔT 0还可以由用户根据实际情况手动进行设置。用户在第一次洗衣程序的最后一次漂洗进水阶段将预设时间间隔ΔT 0的设定值减小至小于一次漂洗加最终脱水所需时间，添加剂投放装置即可在第二次洗衣程序的洗涤进水过程中进行添加剂投放。在第二次洗衣程序的洗涤进水过程中，用户再将预设时间间隔ΔT 0重新调整为接近洗涤设备运行一次洗衣程序所需的最长时间，添加剂投放装置就不会在后续的漂洗进水阶段再次投放洗涤剂。
具体地，所述添加剂投放装置上具有时间设置键4，用户可通过操作时间设置键4进行预设时间间隔ΔT 0的设置。所述添加剂投放装置接收用户的设置信息确定所述预设时间间隔ΔT 0。添加剂投放装置上还设置显示屏3，显示屏3在用户操作时间设置键4的同时实时显示当前预设时间间隔ΔT 0的设定值，更方便用户进行设置操作。
本实施例的另一种方案中，所述的前次进水为本次进水之前、进行添加剂投放的进水。所述时间间隔ΔT具体为前次进行了添加剂投放的进水结束与本次进水开始之间的间隔时间。
在上述方案中，添加剂投放装置根据前次投放添加剂的进水结束与本次进水之间的间隔时间判断本次进水是否投放添加剂。在洗涤设备结束洗涤阶段的进水后，在时间间隔ΔT小于预设时间间隔ΔT 0时，检测到进水也不进行添加剂投放，防止了添加剂投放装置在后续漂洗进水阶段误投洗涤剂的情况。在时间间隔ΔT大于等于预设时间间隔ΔT 0后再检测到洗涤设备进水时，前次洗衣程序已运行完成，此时是另一次洗衣程序的洗涤进水阶段，添加剂投放装置可自动进行洗涤剂投放，无需用户再次操作，使用方便。
上述方案与前一种根据相邻两次进水之间时间间隔进行判断的方案相比，在洗涤设备连续运行多次洗衣程序时，不需要用户手动调整预设时间间隔ΔT 0的设定值，也可以实现洗涤剂的多次投放。因此上述方案的判断结果更加准确，出现误判的几率更低，需要用户的操作更少，使用更加方便。
通过采用上述方案控制添加剂投放装置的工作过程，添加剂投放装置不需要与洗涤设备之间建立通讯连接以获取洗涤设备的运行进程，也可以有效避免添加剂的误投放，可以实现添加剂的自动准确投放，节省了添加剂投放装置的制造成本，同时使添加剂投放装置的适应性更强，可以应用于不具有通讯功能的非联网型洗涤设备。
本实施例中，计时模块优选用于获取前次进行添加剂投放的进水结束与本次开始进水之间的时间间隔ΔT。在时间间隔ΔT大于等于预设时间间隔ΔT 0时，添加剂投放装置在持续进水达到时间阈值t 0后才进行添加剂投放。其中，所述时间阈值t 0大于洗涤设备进行喷淋进水和/或偏心均布进水时所需的最长持续进水时长，且小于洗涤设备进水至最低洗涤水位所需的进水时长。
优选地，所述时间阈值t 0小于洗涤设备进水至最低洗涤水位所需的进水时长的一半。可以保证对于任何洗涤水位的进水过程，添加剂都可以在进水过程进行至一半之前进行添加剂投放，避免添加剂的投放时机过晚，无法与洗涤水混合均匀充分起泡，进而影响洗衣效果。
对于具有进水喷淋功能，或者在脱水阶段通过进水以均布负载消除偏心的洗涤设备，由 于上述进水过程中进水量较小，进水持续时间明显小于洗涤进水所需时间。添加剂投放装置可以根据水流检测模块检测到的持续进水时长将上述进水过程与洗涤进水过程有效地区分开，从而在洗涤进水阶段投放洗涤剂，而避免在其他进水阶段误投洗涤剂的发生。为有效避免洗涤剂的误投，所述时间阈值t 0可以设置为30s左右。
本实施例的优选方案中，若持续进水时长小于时间阈值t 0，计时模块在水流检测模块再次检测到开始进水时重新对持续进水时长计时，以控制是否进行添加剂投放。
本实施例中，计时模块在水流检测模块未检测到进水时用于时间间隔ΔT的计时，在进水过程中用于对持续进水时长进行计时。
具体地，计时模块可以包括第一计时子模块和第二计时子模块。所述第一计时子模块用于时间间隔ΔT的计时，第二计时子模块用于获取进水时长，两者独立工作，控制逻辑更加简单。
第一计时子模块在每次投放了添加剂的进水过程结束后开始计时，当水流检测模块检测到开始进水时反馈当前的时间间隔ΔT。若时间间隔ΔT小于预设时间间隔ΔT 0，添加剂投放装置在本次进水过程中不进行添加剂投放，第一计时子模块继续进行计时。若时间间隔ΔT大于等于预设时间间隔ΔT 0，在持续进水达到时间阈值t 0后，第一计时子模块停止计时并清零，在进水结束后重新开始计时。
当第一计时子模块反馈的时间间隔ΔT大于等于预设时间间隔ΔT 0时，第二计时子模块开始计时，并在持续进水达到时间阈值t 0时进行反馈，添加剂投放装置接收到第二计时子模块的反馈信号后，在本次进水的后续进水过程中进行添加剂投放。水流检测模块检测到进水停止时，第二计时子模块即停止计时并清零，下一次重新从零开始计时。若持续进水未达到时间阈值t 0时即停止，第二计时子模块也停止计时并清零，并在下一次进水时重新从零开始计时。
本实施例的进一步方案中，在水流检测模块检测到持续进水时长达到时间阈值t 0后，添加剂投放装置在本次进水的后续进水过程中执行间歇投放添加剂的投放过程。
在上述方案中，添加剂在进水过程中间歇投入洗涤设备，使添加剂在进水过程中均匀分布在水中，进而在后续洗衣过程中更容易在水中均匀分散，充分溶解，以达到更好的洗衣效果。
具体地，所述间歇投放添加剂的投放过程包括：
持续进水过程中，每经过预设时长T 0，添加剂投放装置执行第一预设投放量X 1的第一投放步骤；
水流检测模块检测到进水停止时，添加剂投放装置结束投放过程；
所述预设时长T 0的设定满足：T 0<t 0，其中，t 0小于洗涤设备进水至最低洗涤水位所需的进水时长的一半。
在上述方案中，添加剂投放装置每间隔固定的进水时长时投放固定量的添加剂，例如每进水10s投放添加剂1ml，使添加剂的投放量与已进水时长始终保持在一定比例，添加剂投 放装置无需预先获知总进水时长，也可以实现对添加剂投放量的准确控制。
本实施例的优选方案中，在第一次执行第一投放步骤前，添加剂投放装置先执行第二预设投放量X 2的第二投放步骤；
其中，第二预设投放量X 2的设定满足：X 2>X 1。
优选地，第二预设投放量X 2的设定满足：X 2/t 0＝X 1/T 0。
本实施例的方案中，将预设时长T 0设置的尽可能小更有利于精确控制添加剂的投放量，而在第一次执行第一投放步骤前，洗涤设备的实际总进水时长为t 0+T 0。添加剂投放装置在第一次执行第一投放步骤前先执行第二投放步骤以向洗涤设备投入第二预设投放量X 2的添加剂，添加剂的总投放量更加精确。另一方面，由于时间阈值t 0大于预设时长T 0，可以保证添加剂投放装置在本次进水过程中进行第一次添加剂投放时，洗涤设备内已经有足够量的水，尤其是对于滚筒洗衣机而言，第一次投放添加剂之前的进水量较大可以先将筒内的排污口填充满，避免添加剂直接被衣物吸收，无法充分溶解在水中，影响洗衣效果。
如图2所示，本实施例中优选在开始进水后持续进水时长达到时间阈值t 0时，即执行第二投放步骤，然后每经过预设时长T 0，执行一次第一投放步骤，直至进水停止。
本实施例的进一步方案中，若添加剂投放装置接收到手动投放指令，在水流检测模块检测到进水后进行添加剂投放，否则根据时间间隔ΔT控制添加剂投放装置是否进行添加剂投放。
优选地，如图1所示，所述添加剂投放装置上设置手动投放键6，所述手动投放指令为手动投放键6被触发。
在上述方案中，用户可通过触发手动投放键6向添加剂投放装置发出手动投放指令，之后添加剂投放装置在水流检测模块检测到进水时即进行添加剂投放，而不再根据时间间隔ΔT判断是否进行投放。
针对采用相邻两次进水之间的间隔时间控制是否投放的方案，用户在连续运行两次洗衣程序时，可以在第二次洗衣程序的洗涤进水开始前触发手动投放键6，以实现洗涤进水阶段的添加剂投放。
当采用前次投放添加剂的进水与本次进水之间的间隔时间控制添加剂投放装置是否进行投放时，在一些特殊情况下，例如用户需要连续运行多次洗涤设备的洗涤程序时，也可以通过手动投放键6发送手动投放指令，以实现在多次连续进水过程中均投放添加剂的目的，而不会由于时间间隔ΔT未达到预设时间间隔ΔT 0无法完成添加剂的投放。
本实施例中，手动投放指令的作用可以是一次性的，也即用户自主判断此次进水需要投放添加剂时，即可触发手动投放键6发出手动投放指令，第一计时子模块停止计时并清零，添加剂投放装置不进行时间间隔ΔT的判断，而在当前正在进行的进水过程中，或者在紧随其后的进水过程中直接进行添加剂投放。本次进水结束后，第一计时子模块开始计时，在水流检测模块再次检测到开始进水时，仍会根据时间间隔ΔT判断是否进行投放。
手动投放指令的作用也可以是持续的，也即用户触发手动投放键6后，添加剂投放装置 每次检测到持续进水时长达到时间阈值t 0后，均在本次进水的后续进水过程中进行添加剂投放，直至手动投放键6再次被触发后，添加剂投放装置才会在检测到开始进水时根据时间间隔ΔT判断是否进行投放。为提示用户添加剂投放装置当前的工作状态，防止用户触发手动投放键6后忘记关闭手动投放功能，还可以通过显示屏3显示当前添加剂投放装置的手动投放功能已开启。
本实施例的另一种方案中，添加剂投放装置具有可开启/关闭的自动投放模式。
在所述自动投放模式下，添加剂投放装置根据时间间隔ΔT控制是否进行添加剂投放，否则添加剂投放装置不进行添加剂投放。
优选地，如图1所示，所述添加剂投放装置上设置自动投放键5，添加剂投放装置接收到自动投放键5被触发的信号时开启自动投放模式。
在上述方案中，添加剂投放装置的自动投放模式可由用户手动开启或关闭。自动投放模式开启时，添加剂投放装置根据时间间隔ΔT控制是否进行添加剂投放。自动投放模式关闭时，添加剂投放装置不进行添加剂投放，从而可以满足用户不同的使用需求，如运行单漂洗程序时，不会投放添加剂。
进一步地，添加剂投放装置上还设置电源键7，添加剂投放装置接通外接电源后，用户通过触发电源键7发出开机指令，添加剂投放装置开机。所述添加剂投放装置开机后，在水流检测模块第一次检测到洗涤设备持续进水达到时间阈值t 0时，在本次进水的后续进水过程中进行添加剂投放。
本次投放过程结束后，若自动投放模式已开启，在之后每次检测到进水时根据时间间隔ΔT控制是否进行添加剂投放。若自动投放模块未开启，添加剂投放装置不再进行添加剂投放。
本实施例的进一步方案中，添加剂投放装置具有预设的待机等待时长T off，若添加剂投放装置检测到持续没有水流通过的时长达到待机等待时长T off时，添加剂投放装置自动进入待机状态。所述待机等待时长T off小于预设时间间隔ΔT 0。
待机状态下，计时模块继续工作，持续计时，水流检测模块、投放机构等均停止工作，不再接收信号。直到添加剂投放装置接收到电源键7被触发的信号时，水流检测模块才重新启动。
在上述方案中，添加剂投放装置可在长时间未检测到进水时自动待机，大多数模块停止工作，可以减少能耗。但计时模块在待机期间持续计时，在添加剂投放装置重新启动并检测到进水时，不影响对时间间隔ΔT的获取，从而可以准确控制是否进行添加剂投放。
本实施例的添加剂投放装置可外置于洗涤设备，从而其容量不受洗涤设备整机体积的限制，可以具有容量更大的储液腔以储存更多的添加剂，减少用户手动补充添加剂的频率。洗涤设备的进水经过添加剂投放装置上的水流检测模块，使得添加剂投放装置可以获知洗涤设备的进水情况，从而根据前次进水与本次进水之间的时间间隔ΔT控制本次进水过程中是否进行添加剂的投放。
添加剂投放装置与洗涤设备分别具有独立的控制系统，添加剂投放装置仅通过时间间隔 ΔT进行判断控制，而不需要与洗涤设备之间建立通讯连接以直接获取洗涤设备的运行进程，节省了制造成本。同时还使得本实施例的添加剂投放装置可以应用于本身不具有通讯功能的洗涤设备，适应能力更强。
