洗衣机的过滤组件的自清洁方法 技术领域
本发明涉及洗衣机，特别是涉及一种洗衣机的过滤组件的自清洁方法。
背景技术
现有常规洗衣机洗衣时的工作流程通常包括进水、洗涤-甩干-排水、多次漂洗-甩干-排水等，其中洗涤和每次漂洗均需要消耗大量的清水。洗涤或漂洗用过的水，通过排水管排放到洗衣机外面环境。整个洗涤过程耗水量比较大，极大地浪费水资源。
为了达到节水的目的，可采用过滤组件对洗衣机的洗涤水和/或漂洗水进行过滤处理，以便循环利用。但随着洗衣机洗涤次数的增多，分离物质以及一些其他杂质会在过滤膜表面逐渐积聚，造成过滤膜的堵塞和污染问题，使其过滤效果会受到较大的影响。由于目前一些洗衣机具备对过滤组件的自动清洁功能，然而，现有的洗衣机在对过滤组件进行清洗不彻底，容易造成清洗药剂等残留在过滤组件上。因此，如何彻底对过滤组件进行清洗是家用洗衣机领域中函待解决的问题。

根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的洗衣机的示意性原理图；
图2是根据本发明实施例的洗衣机的过滤组件的自清洁方法的示意性流程图；
图3是根据本发明又一实施例的洗衣机的过滤组件的自清洁方法的示意性流程图；
图4是根据本发明实施例的洗衣机的自清洁程序的示意性流程图；

图6是根据本发明实施例的洗衣机的自清洁程序中碱液清洗阶段的示意性流程图；
图7是根据本发明实施例的洗衣机的自清洁程序中酸液清洗阶段的示意性流程图。
具体实施方式
图1是根据本发明一个实施例的洗衣机的示意性原理图。该洗衣机可包括洗涤筒12、排水泵22以及过滤组件。过滤组件包括前置过滤器24和超滤膜组件26。洗涤筒12通常由外筒和可在外筒内转动的内筒构成。洗涤筒12上部设有清水进口，其通过管路11连接自来水口，当打开管路11上的阀门13时，可向洗涤筒12中进入洗涤用清水或漂洗用清水。洗涤筒12的下部设有排水口，排水口与过滤组件之间经由排水泵22通过管路连通。超滤膜组件26的产水口通过进水管路14与洗涤筒12连通。
在使用洗衣机的净水洗功能，即采用洗衣机的净水洗程序洗衣时，洗涤筒12中的水被泵送出，输送到过滤组件中进行过滤，被过滤后的水通过超滤膜组件26的产水口、进水管道14返回到洗涤筒12中重用。例如，在洗衣机的净水洗程序中，对衣物进行漂洗时，可使洗涤筒12内的水流入过滤组件，并在过滤组件被过滤后再流回洗涤筒12内；在洗衣机的净水洗程序中，对衣物进行洗涤或脱水时，洗涤筒内的水直接排出洗衣机。
本发明实施例的洗衣机还可包括气泵32，气泵32的出气口通过气流管路与过滤组件的进气口连通。在气流管路上设置有单向阀34。当需要对过滤组件进行气洗时，开启气泵32和单向阀34，气泵32对过滤组件提供气流进行气洗，以利用气流松落截留或粘附在过滤组件内的杂质。粗过滤器24的浓排口和超滤膜组件26的排污口可分别与一三通阀36的两个入口连通，该三通阀36的出口与洗衣机的外排管路18连通，以便将对粗过滤器24和/或超滤膜组件26进行气洗或水洗的流体直接排出洗衣机。洗衣机的洗涤水可经由排水泵22后，流经粗过滤器24且不被粗过滤器过滤地经由三通阀36的出口与洗衣机的外排管路18流出洗衣机。
特别地，本发明实施例的过滤组件以筛分为分离原理，能有效降低衣物残留线屑，可以有效去除漂洗水中微粒、胶体、细菌、微生物以及高分子有机质，以将洗涤水或漂洗水纯化、循环利用，从而达到节水的目的。但随着 洗衣机洗涤次数的增多，分离物质以及一些其他杂质会在过滤组件表面逐渐积聚，造成过滤组件的堵塞和污染问题，其过滤效果会受到一定的影响。针对洗衣机中的过滤组件存在的上述问题，通过对洗衣机的过滤组件进行适当的彻底清洗，可明显改善过滤组件特别是超滤膜组件的过滤效果，延长过滤组件特别是超滤膜组件的使用寿命，并保证过滤组件特别是超滤膜组件在其使用寿命内可靠运行。
本发明实施例的洗衣机的过滤组件的自清洁方法，能够对过滤组件进行彻底的清洗。具体地，洗衣机的过滤组件的自清洁方法可包括：
步骤A：接收启动自清洁程序的用户操作指令。
步骤B：执行自清洁程序，以对洗衣机的过滤组件进行清洗。
在本发明的一些实施例中，参见图2，步骤B还包括：在自清洁程序完成前，仅接收关闭洗衣机的用户操作指令，且禁止接收除关闭洗衣机的用户操作指令外的其余用户操作指令或忽略接收到的除关闭洗衣机的用户操作指令外的其余用户操作指令。
在本发明的一些实施例中，参见图3，步骤B中还包括：在自清洁程序完成前，仅接收关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令，且禁止接收除关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令外的其余用户操作指令或忽略接收到的除关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令外的其余用户操作指令。
为了防止自清洁程序对过滤组件进行清洗的非强制中断，以对过滤组件进行彻底的清洗，防止除关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令外的其余用户操作指令对清洗过滤组件的干扰，洗衣机在执行自清洁程序的过程中可禁止接收除关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令外的其余用户操作指令，例如将生成除关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令外的其余用户操作指令的按键设置成无效状态，或者，洗衣机的用户操作界面只显示与自清洁程序相关的信息。在一些实施例中，洗衣机在执行自清洁程序的过程中也可接收用户操作指令。若接收到用户操作指令，则判断接收到的用户操作指令是否为关闭洗衣机、暂停自清洁程序和取消暂停自清洁程序的用户操作指令，若是，执行关闭洗衣机、暂停对过滤组件的清洗或继续执行对过滤组件的清洗，若否则忽略接收到的用户操作指令。
在本发明的一些实施例中，由于自清洁程序时间比较长，用户在过滤组件不是很脏的情况下，对过滤组件进行清洗，允许强制关闭洗衣机，以结束此次自清洁程序。在一些突发的状况下，也允许用户强制关闭洗衣机，以结束此次自清洁程序，例如洗涤筒漏水、用户在自清洁程序运行一段时间后发现忘记投放清洗药剂等。洗衣机执行自清洁程序的过程中，也允许暂停正在执行的自清洁程序，例如，洗衣机执行自清洁程序的过程中，用户急于外出，为了确保绝对的安全，用户暂停了洗衣机的自清洁程序，待用户重新回到家中，取消暂停后以继续执行自清洁程序的余下步骤。在一些突发的情况下，也允许用户暂停执行自清洁程序，例如，自来水管路停水时。
图3是根据本发明又一实施例的洗衣机的过滤组件的自清洁方法的示意性流程图。在步骤A之前还包括步骤C：根据预设程序判断是否需要对过滤组件进行清洗，若需要对过滤组件进行清洗，则发出对过滤组件进行清洗的提醒信号，以提醒用户向洗衣机的分配器盒投放清洗药剂和启动自清洁程序。具体地，提醒信号可为视觉和/或听觉信号。预设程序可被配置成：当过滤组件的累计产水量达到限定阈值时，判定需要对过滤组件进行清洗，且在完成对过滤组件进行清洗时，将过滤组件的累计产水量清零。
在本发明的一些可替代的实施例中，预设程序可被配置成：当洗衣机的开启次数达到预定开启次数阈值后，和/或当过滤组件运行的累计时间达到预定时间阈值后，和/或当过滤组件的过滤性能指标被检测为下降到预定性能指标阈值后，和/或当洗衣机运行的净水洗程序次数达到净水洗程序预定次数阈值后，判定需要对过滤组件进行清洗，其中洗衣机的开启次数在首次运行洗衣机或清洗了过滤组件后从零起算，过滤组件运行的累计时间在首次运行洗衣机或清洗了过滤组件后从零起算，洗衣机运行的净水洗程序次数在首次运行洗衣机或清洗了过滤组件后从零起算。在一些实施例中，过滤性能指标可为经过滤组件过滤后的循环水的浊度。
在本发明的又一些实施例中，步骤B还包括：在执行自清洁程序的过程中，对已执行的自清洁程序的各个步骤进行记忆，以在洗衣机失去供电后再次获得供电时继续执行自清洁程序的其余步骤，从而保证对过滤组件的彻底清洗。
在一些实施例中，在步骤B之后还包括步骤D：在自清洁程序完成前，接收到关闭洗衣机的用户操作指令并执行关闭洗衣机后，若接收到开启洗衣 机的用户操作指令，执行开启洗衣机。在开启洗衣机后，发出对过滤组件进行清洗的提醒信号，且禁止接收启动净水洗程序的用户操作指令或忽略接收到的启动净水洗程序的用户操作指令。由于洗衣机的过滤组件没有被彻底清洗，为了保护过滤组件，将洗衣机的净水洗程序锁定，以防止使用过滤组件，待重新完成对过滤组件的清洗后，解锁洗衣机的净水洗程序。在本发明实施例中，可通过接收到洗衣机面板上的电源键被按下或触动时，认为接收到关闭洗衣机的用户操作指令，通常也可以理解为洗衣机被强制关机，洗衣机接收到强制关机的用户操作指令。
净水洗程序可包括循环水漂洗阶段，循环水漂洗阶段用于利用漂洗水对洗衣机的洗涤筒内的衣物进行漂洗，在循环水漂洗阶段的循环水漂洗步骤中，洗涤筒内的漂洗水流入过滤组件，并在过滤组件中过滤后流回洗涤筒内。净水洗程序还可包括：在循环水漂洗阶段之前执行的洗涤阶段，以及在循环水漂洗阶段之后执行的脱水阶段。洗涤阶段可包括：洗涤注水步骤，用于从洗衣机的进水管进水从而为洗涤阶段提供洗涤水；洗涤步骤，用于利用洗涤剂和洗涤水对洗涤筒内的衣物进行洗涤；和洗涤脱水步骤，用于将洗涤筒内的衣物脱水。循环水漂洗阶段可包括：漂洗注水步骤，用于从进水管进水从而为循环水漂洗阶段提供漂洗水；循环水漂洗步骤；和漂洗脱水步骤，用于将洗涤筒内的衣物脱水。脱水阶段用于将洗涤筒内的衣物甩干。洗涤脱水步骤和漂洗脱水步骤中衣物脱水时洗涤筒的转速低于脱水阶段脱水时洗涤筒的转速，洗涤脱水步骤和漂洗脱水步骤中衣物脱水的时间低于脱水阶段脱水的时间，其原因在于洗涤脱水步骤和漂洗脱水步骤中衣物脱水只是尽量把衣物中的水分去除，而脱水阶段衣物脱水是要尽可能地把衣物中的水分去除，以便于晾晒。在本发明的一些可替代的实施例中，循环水漂洗阶段无漂洗脱水步骤。
图4是根据本发明实施例的洗衣机的自清洁程序的示意性流程图。自清洁程序可包括依次执行的碱液清洗阶段S10和酸液清洗阶段S20。在碱液清洗阶段S10中，可使用碱性清洗液对过滤组件进行清洗。在酸液清洗阶段S20中，可使用酸性清洗液对过滤组件进行清洗。
碱液清洗阶段S10和酸液清洗阶段S20分别包括各自的注液浸泡步骤，即：将清洗液从洗衣机的洗涤筒中排出，并从过滤组件的进水口中注入过滤组件，直至过滤组件的过滤膜全部地或部分地浸泡在清洗液中后停止清洗液 的注入，已注入的清洗液静置于过滤组件中对过滤组件的过滤膜进行浸泡。在一些实施例中，在注液浸泡步骤中用清洗液对过滤组件进行浸泡的时间可为3～7min，例如为5min。
在一些实施例中，若注液浸泡步骤之后不用对过滤组件进行下一步的清洗，可将洗涤筒内的剩余的清洗液经由过滤组件或者不经由过滤组件排放到洗衣机外。
参见图5，在一些实施例中，碱液清洗阶段S10和酸液清洗阶段S20在其各自的注液浸泡步骤S202之后还可包括气洗步骤S204：将气流注入过滤组件中，对过滤组件进行气洗。在本发明的一些实施例中，可以在洗衣机内部设置气泵，用于提供对过滤组件进行气洗的气流。在气洗步骤S204中，用气流对过滤组件进行气洗的时间为1～3min，例如为2min。对过滤组件进行气洗的气流可从过滤组件排至洗衣机外。
在一些实施例中，碱液清洗阶段S10和酸液清洗阶段S20在其各自的气洗步骤S204之后还可包括：继续循环进行其注液浸泡步骤和气洗步骤，直至完成各自的预定循环次数。其中在气洗步骤S204随后的注液浸泡步骤S202中注入的清洗液将过滤组件中气洗后的清洗液从过滤组件置换到洗衣机外。
在一些实施例中，碱液清洗阶段S10持续的时间可长于酸液清洗阶段S20持续的时间。在一些实施例中，碱液清洗阶段S10的注液浸泡步骤和气洗步骤的碱洗预定循环次数大于酸液清洗阶段S20的注液浸泡步骤和气洗步骤的酸洗预定循环次数。可选地，碱液清洗阶段S10的注液浸泡步骤和气洗步骤的碱洗预定循环次数例如为5-15次，优选10次；酸液清洗阶段S20的注液浸泡步骤和气洗步骤的酸洗预定循环次数例如为2-10次，优选5次。
在一些实施例中，碱液清洗阶段S10和酸液清洗阶段S20在其各自的首次注液浸泡步骤S202之前还包括清洗液准备步骤：向洗涤筒中注水，水流携带已投放在洗衣机的分配器盒内的清洗药剂注入洗涤筒，在洗涤筒内混合成清洗液，并在洗涤筒内将清洗液加热至各自的初始预定温度。在碱液清洗阶段S10的清洗液准备步骤中，碱性清洗液可在洗涤筒内被加热至50～60℃，例如55℃；在酸液清洗阶段S20的清洗液准备步骤中，酸性清洗液可在洗涤筒内被加热至35～45℃，例如40℃。
在一些实施例中，分配器盒可包括第一格腔和第二格腔，分别放置有碱 性清洗药剂和酸性清洗药剂，而且在碱液清洗阶段S10和酸液清洗阶段S20的清洗液准备步骤中，水分别流经第一格腔和第二格腔注入洗涤筒。可由用户将碱性清洗药剂和酸性清洗药剂分别放置在洗衣机的分配器盒的第一格腔和第二格腔内，然后通过洗涤筒的进水管道向分配器盒的第一格腔内注水，水流携带已投放在分配器盒内的碱性清洗药剂注入洗涤筒中，并在其内混合成碱性清洗液，可通过洗衣机内部的加热装置将洗涤筒内的碱性清洗液加热至碱液初始预定温度后，循环执行注液浸泡步骤S202和气洗步骤S204。当碱液清洗阶段S10结束后，通过洗涤筒的进水管道向分配器盒的第二格腔内注水，水流携带已投放在分配器盒内的酸性清洗药剂注入洗涤筒中，并在其内混合成酸性清洗液，可通过洗衣机内部的加热装置将洗涤筒内的酸性清洗液加热至酸液初始预定温度后，循环执行注液浸泡步骤S202和气洗步骤S204。
在一些实施例中，根据洗涤筒内的碱性清洗液的量和碱液清洗阶段S10的注液浸泡步骤S202和气洗步骤S204进行的碱洗预定循环次数，通过液位控制确定在碱液清洗阶段S10的每次注液浸泡步骤S202中的清洗液注入量。例如，在碱液清洗阶段S10的清洗液准备步骤中，洗涤筒内的碱性清洗液共有10L，注液浸泡步骤S202和气洗步骤S204进行的碱洗预定循环次数为10次，那么通过液位控制每次从洗涤筒中泵送十分之一的碱性清洗液至过滤组件中。而不是按流量每次泵送1L的碱性清洗液至过滤组件中。通过液位控制注液浸泡步骤S202泵入的清洗液量，可保证在碱洗预定循环次数内每一次注液浸泡步骤S202中均有足够清洗液，避免由于按流量泵送的误差导致的未达到碱洗预定循环次数时，洗涤筒内已无清洗液的现象。
相应地，在一些实施例中，根据洗涤筒内的酸性清洗液的量和酸液清洗阶段S20的注液浸泡步骤S202和气洗步骤S204进行的酸洗预定循环次数，通过液位控制确定在酸液清洗阶段S20的每次注液浸泡步骤S202中的清洗液注入量。例如，在酸液清洗阶段S20的清洗液准备步骤中，洗涤筒内的酸性清洗液共有5L，注液浸泡步骤S202和气洗步骤S204进行的酸洗预定循环次数为5次，那么每次从洗涤筒中泵送五分之一的酸性清洗液至过滤组件中。
在一些实施例中，由于碱液清洗阶段S10持续的时间较长，为了保障碱性清洗液的温度以使其清洗性能达到最佳状态，在碱液清洗阶段S10中还可对洗涤筒中的清洗液进行二次加热。即碱液清洗阶段S10在其注液浸泡步骤和气洗步骤的循环次数未达到碱洗预定循环次数之前，还包括：
清洗液二次加热步骤：将洗涤筒内剩余的清洗液加热至与碱液清洗阶段S10的清洗液准备步骤中的碱液初始预定温度相同的温度，如50～60℃。
在清洗液二次加热步骤之后继续循环注液浸泡步骤和气洗步骤直至完成碱洗预定循环次数。例如，碱液清洗阶段S10的注液浸泡步骤和气洗步骤循环次数为小于前述碱洗预定循环次数的任选次数时，可执行清洗液二次加热步骤。
在优选实施例中，碱液清洗阶段S10的清洗液二次加热步骤在其注液浸泡步骤和气洗步骤的循环次数达到碱洗预定循环次数的一半时进行。例如，碱液清洗阶段S10的注液浸泡步骤S202和气洗步骤S204进行的碱洗预定循环次数为10次，那么当其注液浸泡步骤S202和气洗步骤S204循环5次以后，即进行清洗液二次加热步骤，当将洗涤筒内剩余的清洗液加热至50～60℃以后，再继续循环5次注液浸泡步骤S202和气洗步骤S204，即可完成碱液清洗阶段S10。
在其他实施例中，还可在整个碱液清洗阶段S10和/或整个酸液清洗阶段S20中利用洗涤筒内的加热装置持续加热以使洗涤筒内的碱性清洗液或酸性清洗液一直保持在碱液初始预定温度或酸性初始预定温度。
图6是根据本发明实施例的洗衣机的自清洁程序中碱液清洗阶段S10的示意性流程图。
碱液清洗阶段S10开始后，可执行清洗液准备步骤S302：向洗涤筒中注入第一预定量的水，水流携带已投放在洗衣机的分配器盒第一格腔内的碱性清洗药剂注入洗涤筒，在洗涤筒内混合成碱性清洗液，并在洗涤筒内将碱性清洗液加热至碱液初始预定温度。
注液浸泡步骤S304：碱性清洗液从洗衣机的洗涤筒中被泵送出，从过滤组件的进水口中注入过滤组件，直至过滤组件的过滤膜全部地或部分地浸泡在碱性清洗液中后停止碱性清洗液的注入。然后将已注入的碱性清洗液静置于过滤组件中对过滤组件的过滤膜进行浸泡。
气洗步骤S306：将气流注入过滤组件中，对过滤组件进行气洗。
第一判断步骤S308：判断循环进行注液浸泡步骤和气洗步骤的次数是否达到预设的第一循环次数，其中第一循环次数小于碱液清洗阶段S10的碱洗预定循环次数。
若是，执行清洗液二次加热步骤S310，若否，重复执行注液浸泡步骤 S304和气洗步骤S306，直至注液浸泡步骤和气洗步骤执行次数达到第一循环次数。在一些实施例中，碱洗预定循环次数可为10次，第一循环次数可为4～6次，优选为5次。
本领域技术人员可以意识到的，在该实施例中，由于每次执行注液浸泡步骤S304后都要执行气洗步骤S306，因此，气洗步骤执行次数与循环进行注液浸泡步骤和气洗步骤的次数相同。在一个实施例中，在第一判断步骤S308中，可仅根据气洗步骤执行次数判断其是否达到第一循环次数。
清洗液二次加热步骤S310：将洗涤筒内剩余的清洗液加热至50～60℃。
注液浸泡步骤S312：重新加热的清洗液从洗衣机的洗涤筒中被泵送出，从过滤组件的进水口中注入过滤组件，直至过滤组件的过滤膜全部地或部分地浸泡在清洗液中后停止清洗液的注入。然后将已注入的清洗液静置于过滤组件中对过滤组件的过滤膜进行浸泡。
气洗步骤S314：将气流注入过滤组件中，对过滤组件进行气洗。
第二判断步骤S316：判断循环进行注液浸泡步骤和气洗步骤的次数是否达到碱液清洗阶段S10的碱洗预定循环次数。
若否，重复执行注液浸泡步骤S312和气洗步骤S314，直至注液浸泡步骤和气洗步骤执行次数达到碱洗预定循环次数。在一些实施例中，也可在清洗液二次加热步骤S310后将注液浸泡步骤和气洗步骤的执行次数归零并重新累计，在第二判断步骤S316中判断循环进行注液浸泡步骤和气洗步骤的次数是否达到碱液清洗阶段S10的第二循环次数，其中第一循环次数与第二循环次数之和为碱洗预定循环次数。
在一些实施例中，碱液清洗阶段在其注液浸泡步骤和气洗步骤完成碱洗预定循环次数之后，还包括冲洗步骤S318：将预定量的清水从洗衣机的洗涤筒中泵入过滤组件中对其进行冲洗后排放到洗衣机外。在具体的实施例中，在结束碱液清洗阶段S10的所有注液浸泡步骤和气洗步骤之后(在最后一次注液浸泡步骤中，已将洗涤筒内的碱性清洗液全部泵出或有少量残留)，可重新向洗涤筒中注入第二预定量的水，水流经洗衣机的分配器盒第一格腔注入洗涤筒，将预定量的清水从洗衣机的洗涤筒中泵入过滤组件中对其进行冲洗后排放到洗衣机外。在冲洗步骤S318中，可包括对过滤组件进行预定次数的冲洗，以达到将洗涤筒及过滤组件以及其间流路内残留碱液排走的目的。冲洗步骤S318后，碱液清洗阶段S10结束，进入酸液清洗阶段S20。
图7是根据本发明实施例的洗衣机的自清洁程序中酸液清洗阶段S20 的示意性流程图。
酸液清洗阶段S20开始后，可执行清洗液准备步骤S402：向洗涤筒中注第三预定量的水，水流携带已投放在洗衣机的分配器盒内的酸性清洗药剂注入洗涤筒，在洗涤筒内混合成酸性清洗液，并在洗涤筒内将酸性清洗液加热至酸液初始预定温度。
注液浸泡步骤S404：酸性清洗液从洗衣机的洗涤筒中被泵送出，从过滤组件的进水口中注入过滤组件，直至过滤组件的过滤膜全部地或部分地浸泡在酸性清洗液中后停止酸性清洗液的注入。然后将已注入的酸性清洗液静置于过滤组件中对过滤组件的过滤膜进行浸泡。
气洗步骤S406：将气流注入过滤组件中，对过滤组件进行气洗。
判断步骤S408：判断循环进行注液浸泡步骤S402和气洗步骤S404的次数是否达到酸液清洗阶段S20的酸洗预定循环次数。
若否，重复执行注液浸泡步骤S402和气洗步骤S404，直至注液浸泡步骤和气洗步骤执行次数达到酸洗预定循环次数。
在一些实施例中，酸液清洗阶段在其注液浸泡步骤和气洗步骤完成碱洗预定循环次数之后，还包括冲洗步骤S410：将预定量的清水从洗衣机的洗涤筒中泵入过滤组件中对其进行冲洗后排放到洗衣机外。在具体的实施例中，在结束酸液清洗阶段S20的所有注液浸泡步骤和气洗步骤之后(在最后一次注液浸泡步骤中，已将洗涤筒内的酸性清洗液全部泵出或有少量残留)，可重新向洗涤筒中注入第四预定量的水，水流经洗衣机的分配器盒第一格腔或第二格腔注入洗涤筒，将预定量的清水从洗衣机的洗涤筒中泵入过滤组件中对其进行冲洗后排放到洗衣机外。在冲洗步骤S410中，可包括对过滤组件进行预定次数的冲洗，以达到将洗涤筒及过滤组件以及其间流路内残留酸液排走的目的。冲洗步骤S410后，酸液清洗阶段S20结束，完成对过滤组件的清洗。
通过上述自清洁方法对洗衣机的过滤组件进行适当的清洗，可明显改善过滤组件的过滤效果，延长过滤组件的使用寿命，并保证过滤组件在其使用寿命内可靠运行。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
