具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种空调器蒸发器水洗控制方法。
参照图1，图1为本发明空调器蒸发器水洗控制方法的第一实施例的流程示意图。在本发明一实施例中，所述方法包括：
步骤S10，控制三通阀连通加水管，并控制加水水泵开启，加水水泵将水箱流入水槽中的水打入加水管，并控制加水管往蒸发器注入水以清洗蒸发器；
参考图2a和图2b，本发明实施例的空调器包括：蒸发器1、水箱2、水槽3、加水水泵4和加水管5，所述蒸发器1的底部设置有接水盘11，所述水箱2与所述水槽3连通，所述接水盘11靠近水槽3的一端设置有出水口12，所述出水口12连接有出水管13，所述出水管13连通所述接水盘11和所述水槽3，所述加水水泵4设置在所述水槽3内，所述加水管5和所述加水水泵4间通过三通阀14连接，所述三通阀14还连接有排水管15，在实际运用过程中，通过对三通阀14的控制，控制三通阀14连通加水管5，也可以通过对三通阀14的控制，控制三通阀14连通排水管15。通过三通阀14的切换，实现加水水泵4连通加水管5向蒸发器1注水，以及切换至加水水泵4连通排水管15，将水排出空调器外部。
在本实施例中，在空调器开启后，按照默认或者用户设置的参数运行。在需要对蒸发器清洗时，控制进入蒸发器清洗模式。所述控制进入蒸发器清洗模式可以包括：1）接收蒸发器清洗指令，根据蒸发器清洗指令进入蒸发器清洗模式；2）获取空调器的总运行时长，在总运行时长达到预设时长（100小时或120小时等，根据需求和环境设置，例如，环境灰尘比较大，则预设时长设置的短一些，为80小时或90小时等，在环境灰尘少，则预设时长设置的长一些，为120小时或130小时等）时，自动进入蒸发器清洗模式。
在进入蒸发器清洗模式时，控制三通阀14连通加水管5，并控制加水水泵4开启，加水水泵4将水箱2流入水槽1中的水打入加水管5，并控制加水管5往蒸发器1注入水以清洗蒸发器1。
优选地，所述加水管5对着蒸发器1的一端设置有喷头，通过喷头喷洒水至蒸发器1，提高水与蒸发器1的接触面积，通过喷入加大对蒸发器1的清洗力度。可以理解的是，所述加水管5还可以是对着所述蒸发器1的中部或中下部位置喷水，在不是对着蒸发器1的上端喷水时，加水管5连接的喷头需喷洒量的设置。具体的设置为，靠近上端的喷水量大于下端喷水量。
步骤S20，将接水盘中的水通过其出水口流入水槽实现对蒸发器的循环水洗；
在清洗蒸发器1时，接水盘11收集清洗蒸发器1的水，接水盘11中收集的水通过出水口12和出水管13流入水槽3，通过加水水泵4和加水管5将流入接水盘11中流入水槽3的水打入蒸发器1蒸发清洗蒸发，通过循环利用清洗蒸发器1的水，避免资源浪费。优选地，在循环清洗过程中，获取水槽中水位的增加速度；在所述增加速度大于预设阈值时，提高加水水泵的转速或控制水箱停止向水槽供水。所述预设阈值为一个警戒的增长速度，在所述预设阈值下的增加速度，水槽中的水不会溢出。通过在增加速度大于预设阈值时，提高加水水泵4的转速，尽快将水槽中的水打入蒸发器1以清洗蒸发器1避免水槽3水溢出，或者控制水箱2停止向水槽3中供水，在增加速度小于预设阈值后，再供水或者停止供水，降低加水水泵4的转速至加水水泵4在安全水位下运行。
步骤S30，在循环水洗第一预设时间后，控制三通阀连通排水管，将接水盘中的水排至空调器外部。所述第一预设时间根据用户需求设置，例如，可以是5分钟或8分钟等，在此期间内空调器的蒸发器1比较脏，洗出来的水也比较脏，因此第一预设时间设置的要相对较短。在循环水洗第一预设时间后，控制三通阀连通排水管，将接水盘11中的水排至空调器外部，即，将脏水排至室外，后续通过干净的水循环清洗蒸发器1。
本实施例通过将水箱2中的水通过加水水泵4喷洒至蒸发器1，对空调器的蒸发器1进行清洗，且在前期先循环清洗，清洗第一预设时间后，排出脏水，避免脏水一直清洗蒸发器1。在保证清洗空调器的蒸发器1的同时，通过水的循环利用，避免资源的浪费，提高室内环境的同时，节省资源，通过三通阀14在将水打入蒸发器1和排至空调器外部之间切换，节省零部件，降低成本。
在本发明一较佳实施例中，参考图3，所述在循环水洗第一预设时间后，控制三通阀连通排水管，将接水盘中的水排至空调器外部之后，还包括：
步骤S40，在将接水盘中的水排至空调器外部第二预设时间后，控制三通阀连通加水管，将接水盘中的水通过其出水口流入水槽实现对蒸发器的循环水洗，并重新计时；
步骤S50，在循环水洗第三预设时间后，控制三通阀连通排水管，将接水盘中的水排至空调器外部。所述第二预设时间与第一预设时间和排水的速度相关联，在第一预设时间越长且排水的速度慢时，第二预设时间设置的越长；在第一预设时间越短且排水的速度快时，第二预设时间设置的越短。所设置的第二时间是为了将接水盘11中的脏水排出，以通过干净的水对空调器的蒸发器1进行清洗。在将接水盘11中的水排至空调器外部第二预设时间后，控制三通阀14连通加水管5，将接水盘11中的水通过其出水口流入水槽3实现对蒸发器1的循环水洗，并重新计时，这里需要重新计时是，在循环清洗一段时间后，需要将脏水排出，才能保证蒸发器1清洗干净。可选地，所述第三预设时间大于所述第一预设时间，因，后面清洗蒸发器1的水更加干净，可以多次更久的循环清洗，因此，第三预设时间大于第一预设时间，进一步节省水资源。在循环水洗第三预设时间后，将接水盘中的水排至空调器外部。在排出外部后，如还未清洗完毕，继续循环清洗，继续排出室外，根据不同的时间和要求来控制循环清洗和排出室外的时间，在保证清洗蒸发器1的同时，尽可能的节省资源。
在本发明一较佳实施例中，参考图4，所述方法还包括：
步骤S60，在排水至空调器外部的次数达到预设阈值后，控制三通阀连通加水管，控制持续对蒸发器循环水洗；
步骤S70，在循环水洗的持续时间达到第四时间后，停止加水水泵的运行，并控制三通阀连通排水管，将接水盘中的水排空。在按照实施例2中的步骤循环清洗蒸发器1后，判断排水至空调器外部的次数是否达到预设阈值。所述预设阈值可以是3次或4次等，在排水至空调器外部的次数达到预设阈值后，空调器中清洗的水基本干净，无需再次向外部排出，控制三通阀连通加水管，控制持续对蒸发器1循环水洗，通过循环使用的水对空调器清洗，在水洗过程中，降低加水水泵4的转速，控制对蒸发器1的下部进行水洗，因加水水泵4转速降低，对蒸发器1的冲击力会降低，也就是说，水会顺着蒸发器留到蒸发器1底部，停留在蒸发器1的时间会越长，清洗效果会越好。在循环水洗的持续时间达到第四时间后，停止加水水泵的运行，并控制三通阀14连通排水管15，将接水盘中的水排空。所述第四预设时间根据需求设置，例如，可以为10分钟或15分钟，为最后清洗蒸发器1的过程，在该过程中蒸发器1清洗的水比较干净，只要循环水洗几次后，即可将蒸发器1清洗干净，在清洗时间达到第四预设时间后，蒸发器1的清洗结束停止加水水泵的运行，并将接水盘11中的水排空。通过对蒸发器1的清洗，使得空调器向室内输出干净的空气，提高室内环境空气质量，且通过排水和循环水洗的控制，节省资源。
基于上述方法，本发明还提出一种空调器蒸发器水洗控制装置，参考图5，所述装置包括：控制模块10和水洗模块20。
所述控制模块10，用于控制三通阀连通加水管，并控制加水水泵开启，加水水泵将水箱流入水槽中的水打入加水管；

在本实施例中，在空调器开启后，按照默认或者用户设置的参数运行。在需要对蒸发器清洗时，控制进入蒸发器清洗模式。所述控制进入蒸发器清洗模式可以包括：1）接收蒸发器清洗指令，根据蒸发器清洗指令进入蒸发器清洗模式；2）获取空调器的总运行时长，在总运行时长达到预设时长（100小时或120小时等，根据需求和环境设置，例如，环境灰尘比较大，则预设时长设置的短一些，为80小时或90小时等，在环境灰尘少，则预设时长设置的长一些，为120小时或130小时等）时，自动进入蒸发器清洗模式。
在进入蒸发器清洗模式时，控制模块10控制三通阀14连通加水管5，并控制加水水泵4开启，加水水泵4将水箱2流入水槽1中的水打入加水管5；
所述水洗模块20，用于控制加水管往蒸发器注入水以清洗蒸发器。
优选地，所述加水管5对着蒸发器1的一端设置有喷头，通过喷头喷洒水至蒸发器1，提高水与蒸发器1的接触面积，通过喷入加大对蒸发器1的清洗力度。可以理解的是，所述加水管5还可以是对着所述蒸发器1的中部或中下部位置喷水，在不是对着蒸发器1的上端喷水时，加水管5连接的喷头需喷洒量的设置。具体的设置为，靠近上端的喷水量大于下端喷水量。
所述水洗模块20，还用于将接水盘中的水通过其出水口流入水槽实现对蒸发器的循环水洗；
在清洗蒸发器1时，接水盘11收集清洗蒸发器1的水，接水盘11中收集的水通过出水口12和出水管13流入水槽3，通过加水水泵4和加水管5将流入接水盘11中流入水槽3的水打入蒸发器1蒸发清洗蒸发，通过循环利用清洗蒸发器1的水，避免资源浪费。优选地，在循环清洗过程中，获取水槽中水位的增加速度；在所述增加速度大于预设阈值时，提高加水水泵的转速或控制水箱停止向水槽供水。所述预设阈值为一个警戒的增长速度，在所述预设阈值下的增加速度，水槽中的水不会溢出。通过在增加速度大于预设阈值时，提高加水水泵4的转速，尽快将水槽中的水打入蒸发器1以清洗蒸发器1避免水槽3水溢出，或者控制水箱2停止向水槽3中供水，在增加速度小于预设阈值后，再供水或者停止供水，降低加水水泵4的转速至加水水泵4在安全水位下运行。
所述控制模块10，还用于在循环水洗第一预设时间后，控制三通阀连通排水管，将接水盘中的水排至空调器外部。所述第一预设时间根据用户需求设置，例如，可以是5分钟或8分钟等，在此期间内空调器的蒸发器1比较脏，洗出来的水也比较脏，因此第一预设时间设置的要相对较短。在循环水洗第一预设时间后，控制三通阀连通排水管，将接水盘11中的水排至空调器外部，即，将脏水排至室外，后续通过干净的水循环清洗蒸发器1。
本实施例通过将水箱2中的水通过加水水泵4喷洒至蒸发器1，对空调器的蒸发器1进行清洗，且在前期先循环清洗，清洗第一预设时间后，排出脏水，避免脏水一直清洗蒸发器1。在保证清洗空调器的蒸发器1的同时，通过水的循环利用，避免资源的浪费，提高室内环境的同时，节省资源，通过三通阀14在将水打入蒸发器1和排至空调器外部之间切换，节省零部件，降低成本。
在本发明一较佳实施例中，参考图5，所述控制模块10，还用于在将接水盘中的水排至空调器外部第二预设时间后，控制三通阀连通加水管，将接水盘中的水通过其出水口流入水槽实现对蒸发器的循环水洗，并重新计时；
所述控制模块10，还用于在循环水洗第三预设时间后，控制三通阀连通排水管，将接水盘中的水排至空调器外部。所述第二预设时间与第一预设时间和排水的速度相关联，在第一预设时间越长且排水的速度慢时，第二预设时间设置的越长；在第一预设时间越短且排水的速度快时，第二预设时间设置的越短。所设置的第二时间是为了将接水盘11中的脏水排出，以通过干净的水对空调器的蒸发器1进行清洗。在将接水盘11中的水排至空调器外部第二预设时间后，控制三通阀14连通加水管5，将接水盘11中的水通过其出水口流入水槽3实现对蒸发器1的循环水洗，并重新计时，这里需要重新计时是，在循环清洗一段时间后，需要将脏水排出，才能保证蒸发器1清洗干净。可选地，所述第三预设时间大于所述第一预设时间，因，后面清洗蒸发器1的水更加干净，可以多次更久的循环清洗，因此，第三预设时间大于第一预设时间，进一步节省水资源。在循环水洗第三预设时间后，将接水盘中的水排至空调器外部。在排出外部后，如还未清洗完毕，继续循环清洗，继续排出室外，根据不同的时间和要求来控制循环清洗和排出室外的时间，在保证清洗蒸发器1的同时，尽可能的节省资源。

所述控制模块10，还用于在循环水洗的持续时间达到第四时间后，停止加水水泵的运行，并控制三通阀连通排水管，将接水盘中的水排空。在按照上述实施例中的过程循环清洗蒸发器1后，判断排水至空调器外部的次数是否达到预设阈值。所述预设阈值可以是3次或4次等，在排水至空调器外部的次数达到预设阈值后，空调器中清洗的水基本干净，无需再次向外部排出，控制三通阀连通加水管，控制持续对蒸发器1循环水洗，通过循环使用的水对空调器清洗，在水洗过程中，降低加水水泵4的转速，控制对蒸发器1的下部进行水洗，因加水水泵4转速降低，对蒸发器1的冲击力会降低，也就是说，水会顺着蒸发器留到蒸发器1底部，停留在蒸发器1的时间会越长，清洗效果会越好。在循环水洗的持续时间达到第四时间后，停止加水水泵的运行，并控制三通阀14连通排水管15，将接水盘中的水排空。所述第四预设时间根据需求设置，例如，可以为10分钟或15分钟，为最后清洗蒸发器1的过程，在该过程中蒸发器1清洗的水比较干净，只要循环水洗几次后，即可将蒸发器1清洗干净，在清洗时间达到第四预设时间后，蒸发器1的清洗结束停止加水水泵的运行，并将接水盘11中的水排空。通过对蒸发器1的清洗，使得空调器向室内输出干净的空气，提高室内环境空气质量，且通过排水和循环水洗的控制，节省资源。
基于上述空调器蒸发器水洗控制装置，本发明还提出一种空调器，所述空调器包括压缩机、蒸发器、水箱、水槽、加水水泵、加水管、接水盘、三通阀和排水管，所述空调器蒸发器清洗控制装置运行在所述空调器，通过控制压缩机、蒸发器、水箱、水槽、加水水泵、加水管、接水盘以及三通阀的切换，对空调器的蒸发器上的水加热，通过热水清洗蒸发器，通过三通阀的切换实现将清洗蒸发器的水在空调器内循环使用和排出至空调器外部的切换。本实施例的空调器通过将水箱中的水通过加水水泵喷洒至蒸发器，对空调器的蒸发器进行清洗，且在前期先循环清洗，清洗第一预设时间后，排出脏水，避免脏水一直清洗蒸发器。在保证清洗空调器的蒸发器的同时，通过水的循环利用，避免资源的浪费，提高室内环境的同时，节省资源，通过三通阀在将水打入蒸发器和排至空调器外部之间切换，节省零部件，降低成本。
