Description

吸水泵组件及其控制方法 技术领域
本公开涉及吸水泵相关领域，例如涉及一种吸水泵组件及其控制方法。
背景技术
随着技术的不断发展进步，全自动洗衣机也逐渐得到了普及。但是对于一些经济条件和配套设施相对落后的农村，存在自来水系统没有普及的情况，在该种情况下，大部分还是采用手洗的方式，导致全自动洗衣机无法实现其应有的使用价值。
为了使全自动洗衣机能够适用于上述环境，通常会配备吸水泵来配合洗衣机使用，由吸水泵来实现全自动洗衣机的进水。现有吸水泵分为内置泵和外置泵两种，上述两种吸水泵均通过洗衣机来控制吸水泵进水的启停。然而由于相关技术中的外置吸水泵通常采用单独通电工作，其不受洗衣机的控制，只要不拔电源就会不中断的运行，导致在洗衣机关闭进水时，吸水泵也会一直运行，而长时间的工作会影响吸水泵的寿命。
发明内容
本公开提供一种吸水泵组件及其控制方法，以解决相关技术中的外置吸水泵通电一直运行，影响吸水泵寿命的问题。
一种吸水泵组件，包括吸水泵，与吸水泵出口相连接的给水管，在所述给水管上设有水流检测装置，所述水流检测装置连接于控制器，所述控制器连接有电源，并能够根据水流检测装置的信号接通或断开对所述吸水泵的供电。
可选地，所述水流检测装置为水流开关。
可选地，所述水流开关包括设置在给水管内的叶轮，内嵌在叶轮上的磁铁，以及设置在给水管内且连接于控制器的磁敏开关，所述磁铁控制所述磁敏开关吸合。
可选地，所述电源为适配器电源。
可选地，所述控制器设置在所述适配器电源内。
可选地，所述控制器通过线缆连接于吸水泵，所述线缆通过抱箍收紧在给水管外壁上。
可选地，所述吸水泵设置有至少一个，且在吸水泵设置多个时，多个吸水泵的出口均连通于所述给水管。
本公开还提供一种吸水泵组件的控制方法，包括：在与吸水泵出口相连接的给水管上设置水流检测装置，在对所述吸水泵供电的同时持续检测水流信号，当所述水流检测装置检测不到水流信号，则通过控制器断开对所述吸水泵的供电。
可选地，还包括：
在控制器断开对所述吸水泵的供电后，控制器周期性接通对吸水泵的供电，并在供电预设时间后通过水流检测装置持续检测水流信号，当所述水流检测装置检测不到水流信号时，通过控制器断开对所述吸水泵的供电。
可选地，所述水流检测装置为水流开关。
本公开的吸水泵组件及其控制方法，可有效适用于缺少自来水系统的环境，而且在给水管内设置水流检测装置，以及设置控制器，能够通过水流检测装置检测的水流信号情况，接通或断开对吸水泵的供电。避免了相关技术中的外置吸水泵接通电源就不中断运行的情况，有效地提高了吸水泵的使用寿命。

具体实施方式
本实施例提供一种吸水泵组件，如图1所示，该吸水泵组件包括吸水泵1、给水管2、水流检测装置3、控制器4以及电源5，其中，
上述吸水泵1可以设置为一个，此时给水管2连接于吸水泵1的出口；上述吸水泵1也可以设置为多个，此时上述多个吸水泵1的出口均连通于该给水管2，即多个吸水泵1运行时，多个吸水泵1吸水至该给水管2内，并经该给水 管2将水泵送至待使用场地。本实施例中，吸水泵1设置为一个。
上述水流检测装置3安装在给水管2内部，水流检测装置3的安装位置可以根据需要设置在给水管2对应位置，本实施例中，该水流检测装置3安装在给水管2出口处。上述水流检测装置3连接于控制器4，用于向控制器4发送水流信号，控制器4则连接上述电源5，通过水流检测装置3以及电源5的设置，控制器4能够根据水流检测装置3检测的水流信号情况接通或断开对吸水泵1的供电。
本实施例中，上述水流检测装置3可以为水流开关，也可以是其他能够检测水流的装置，例如电磁流量计，此时该电磁流量计安装在给水管2出口处。本实施例中，选用水流开关。
如图2，水流开关包括设置在给水管2内的叶轮31，内嵌在叶轮31上的磁铁32，以及设置在给水管2内的磁敏开关33，上述磁敏开关33连接于控制器4，用于向控制器4发送水流信号。一实施例中，上述叶轮31在水流的带动下能够转动，进而带动磁铁32转动，在磁铁32转动至靠近磁敏开关33的位置处时，磁敏开关33被磁铁32的磁力带动吸合并发送水流信号至控制器4，在磁铁32转动离开靠近磁敏开关33的位置处时，磁敏开关33断开，经过上述磁敏开关33的一次通断，磁敏开关33即可产生一次水流信号，并可将该水流信号传递给控制器4，控制器4则接通对吸水泵1的供电，使吸水泵1能够持续运行。
本实施例中，上述电源5可以是固体电源，也可以是适配器电源，本实施例中选用适配器电源，适配器电源可以直接连接于家庭用电。一实施例中，上述控制器4可以设置在上述适配器电源内，以避免控制器4暴露在外部易损坏，影响用户的使用。
上述控制器4通过线缆6连接于吸水泵1，并且该线缆6通过至少一个抱箍7收紧在给水管2外壁上，以减少线缆6的杂乱摆放，且能够避免线缆6落入水中，造成不必要的损坏。
本实施例的上述吸水泵组件在工作时，首先接通电源5，随后通过控制器4接通对吸水泵1的供电，使吸水泵1启动运行，此时水会被吸水泵1泵入给水管2内，给水管2内的水流检测装置3的叶轮31被带动转动，使得水流检测装置3的磁敏开关33发送水流信号给控制器4，控制器4在接收到水流信号后，会控制吸水泵1持续运行，给水管2会持续输送水。当用户不需要用水时，给 水管2的出口会被关闭停止出水，此时给水管2内的水不再流动，水流检测装置3的磁敏开关33则不发送水流信号，此时控制器4接收不到水流信号，就会断开对吸水泵1的供电，使吸水泵1停止运行。通过上述设置，避免了相关技术中外置吸水泵1接通电源5就不中断运行的情况，有效地提高了吸水泵1的使用寿命。
需要说明的是，本实施例的上述吸水泵组件可广泛应用于在供水系统缺乏环境下的各种电器，例如洗衣机、洗碗机等需要有水才能使用的电器。也可以应用于其他非电器使用的场景。
在上述吸水泵组件的基础上，本实施例还提供一种吸水泵组件的控制方法，可选地，如图3所示，该控制方法包括步骤110-步骤130：
在步骤110中，运行吸水泵1。
可选地，在接通电源5后，通过控制器4接通对吸水泵1的供电，使吸水泵1运行。
在步骤120中，在对所述吸水泵1供电的同时持续检测水流信号，当水流检测装置3检测不到水流信号时，通过控制器4断开对吸水泵1的供电。
即在吸水泵1运行后，给水管2内会有水流出，此时位于给水管2内的水流检测装置3会发出水流信号给控制器4，当控制器4接收到该水流信号时，控制器4会控制吸水泵1持续运行，也就是水会被吸水泵1持续输送。当水流检测装置3检测不到水流信号时，即控制器4没有接收到水流信号时，此时说明给水管2内的水没有流动，即此时不再需要吸水泵1泵送水，此时控制器4断开对吸水泵1的供电，使吸水泵1停止运行。
在步骤130中，在控制器4断开对吸水泵1的供电后，控制器4周期性接通对吸水泵1的供电，并在供电预设时间后通过水流检测装置3持续检测水流信号，当水流检测装置3检测不到水流信号时，通过控制器4断开对吸水泵1的供电。
在控制器4断开对吸水泵1的供电后，考虑有可能用户会多次使用水，为了实现吸水泵1的吸水以及该吸水泵组件的自动运行，控制器4会周期性接通对吸水泵1的供电(即每隔一段时间，就会接通对吸水泵1的供电)，使吸水泵1启动运行，并且在对吸水泵1供电预设时间后，控制器4接收到水流检测装置3检测的水流信号时，接通对吸水泵1的供电，控制器4接收不到水流检测装置 3检测的水流信号时，断开对吸水泵1的供电。
可选地，当用户再一次用水时，此时出水管2的出口会被打开，在控制器4周期性接通对吸水泵1的供电的前提下，吸水泵1会启动并开始吸水，此时给水管2内的水会流动，也就使得水流检测装置3检测到水流信号并发送给控制器4，控制器4则控制吸水泵1持续运行；当用户不再需要用水时，给水管2的出口会被关闭停止出水，此时给水管2内的水不再流动，水流检测装置3不会发送水流信号给控制器4，控制器4接收不到水流信号，就会断开对吸水泵1的供电，使吸水泵1停止运行。
通过步骤130，可有效实现用户再次用水时对吸水泵1的自动控制，提高了整个吸水泵组件的自动化程度，便于用户使用。
本实施例中，需要说明的是，上述水流检测装置3的叶轮31带动磁铁32旋转一周，磁铁32控制磁敏开关33吸合一次，磁敏开关33则产生一次水流信号并发送至控制器4。
工业实用性
