具体实施方式
微线屑也叫微纤维，是指长度小于5mm的纤维颗粒。
2011年，Browne等人提出合成纤维服装家庭洗涤是微纤维的重要来源，经过实验表明，一件合成纤维的服装单次洗涤可以释放超过1900根纤维颗粒，这一实验引起了人们对家庭洗涤释放微纤维来源的重视。国际自然保护联盟于2017年发表了一份关于排放至海洋、土壤中微纤维的研究报告，报告中显示合成织物的洗涤可以将35％的 纤维释放到洗涤水中，对海洋、土壤等环境造成污染。例如，海洋中的微纤维被鱼类等海洋生物摄食后，人类再摄食体内有微纤维的鱼等海洋动物，会造成肠道损伤等，对人体造成伤害。
另外，随洗涤水一起排放的微纤维进入土壤环境中与其他有机污染物结合以后，由于微纤维的粒径小，比表面积大，吸附能力强，进而会改变土壤的理化性质，影响土壤生态系统的健康。
其中，微纤维主要通过摄食途径影响土壤中的动物：微纤维经土壤动物摄食后，可造成肠道损伤，容易在体内结块，影响进食和排泄，导致成活率、体长和繁殖能力显著下降。
微纤维可能会改变土壤生态系统的微生物群落和生物多样性：土壤中微纤维的存在可能成为其他有毒有害物质的载体，随着微纤维的迁移，会对土壤中微生物产生影响，进而影响土壤生态系统的健康。
而据统计，2013年全球家庭洗衣机数量已经达到8.4亿台，随着人口数量的不断增加，全球合成纤维纺织品消费量、洗衣机数量以及洗衣频率也会随之增加，因此，为了减小随洗涤水一起排放的微纤维。
相关技术中，在洗衣机的排水管路上设置有用于收集洗涤水中线屑的过滤网，当洗涤腔内的洗涤水通过排水管路排出机体外时，过滤网用于过滤洗涤水中的线屑，从而减小洗涤水中的线屑数量。但是，过滤网的网孔的大小会直接影响洗衣机的排水效率，过滤网的网孔过小，会导致洗衣机的排水效率降低，从而导致洗衣机的洗涤周期延长，因此，相关技术中，为了提高洗衣机的排水效率，通常采用网孔相对较大的过滤网。
然而，网孔较大的过滤网只能过滤尺寸较大的线屑，过滤精度很低，过滤效果较差，洗涤水中依然存在大量的微线屑，而微线屑随洗涤水排出会对环境造成污染。
为了解决上述问题，本申请提供一种洗衣机的控制方法以及洗衣机。本申请提供的洗衣机能够在保证洗衣机高排水效率的同时，对洗涤水中的微线屑进行过滤，减少洗涤水中的微线屑，从而避免微线屑造成的环境污染。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
下面将以滚筒洗衣机为例对其具体结构进行介绍：
图1是本申请实施例提供的洗衣机的正面示意图；图2是本申请实施例提供的洗衣机的内部结构示意图；图3是本申请实施例提供的洗衣机中排水过滤器的结构示意图；图4是图3的内部结构示意图。如图1和图2所示，本申请实施例提供一种洗衣机100，包括：本体110，本体110具有容纳洗涤水的洗涤腔114。具体的，本体110包括机壳111，机壳111具有容纳空间，容纳空间内设置有外筒112和套设在外筒112内的内筒113，其中，外筒112和内筒113同轴设置，外筒112和内筒113之间形成环形的洗涤腔114，洗涤腔114用于容纳洗涤水，待洗涤的衣物放置在内筒113中，内筒113的筒壁上具有若干个通孔，以使洗涤腔114内的洗涤水可以进入内筒113内对衣物进行洗涤。
可选的，外筒112具有与洗涤腔114连通的排水口1141和回水口1142，这样，洗涤腔114内的洗涤水可经排水口1141排出洗涤腔114，或者洗涤水可经回水口1142再次进入洗涤腔114内进行循环洗涤。
在一些实施例中，排水口1141和回水口1142可间隔设置在外筒112的底部。
可选的，如图2至图4所示，机壳111的容纳空间内设置有排水过滤器120，排水过滤器120包括依次连通的第一过滤腔121和第二过滤腔122，第一过滤腔121与洗涤腔114的排水口1141连通，例如，第一过滤腔121具有注水口1211，洗涤腔114的排水口1141通过连通管与注水口1211连通，以使洗涤水经排水口1141和注水口1211进入排水过滤器120的第一过滤腔121内。
另外，第二过滤腔122具有第一出水口1221和第二出水口1222，第一出水口1221可通过连通管与洗涤腔114的回水口1142连通，第二出水口1222与洗衣机100的排水管130连通，这样，当第一出水口1221打开时，洗涤腔114内的洗涤水流经第一过滤腔121、第二过滤腔122再经第一出水口1221从回水口1142处返回至洗涤腔114内继续洗涤，形成洗涤水的内循环通道；而当第二出水口1222打开时，洗涤腔114内的洗涤水流经第一过滤腔121从第二出水口1222排出洗衣机100外，形成洗涤水的排水通道。
可选的，继续参见图4所示，第一过滤腔121内设置有第一过滤件123，第一过滤件123用于过滤进入第一过滤腔121内的线屑；第二过滤腔122内设置有第二过滤件124，第二过滤件124用于过滤进入第二过滤腔122内的线屑。
其中，第一过滤件123的过滤精度小于第二过滤件124的过滤精度，例如，第一过滤件123可过滤的线屑的长度、粒径等尺寸大于第二过滤件124可过滤的线屑的长度、粒径等尺寸，这样，通过第一过滤件123过滤洗涤水中的粗线屑，通过第二过滤件124过滤洗涤水中的微线屑，这样，可以提高对洗涤水中线屑的过滤效果，减少洗涤水中的微线屑，从而减少环境污染。
另外，第二过滤件124可在外力作用下在第二过滤腔122内移动，以选择性的打开第一出水口1221和第二出水口1222中的一者，而封堵第一出水口1221和第二出水口1222中的另一者。
可选的，第二出水口1222位于第一出水口1221和第一过滤腔121之间，这样，当第二出水口1222打开排水时，洗涤水不用经过第二过滤件124，从而可以提高排水时的效率，进而缩短洗涤周期。
需要说明的是，第二过滤件124安装在第二过滤腔122内后，第二过滤件124的侧壁刚好封堵住第二出水口1222，这样，当第二过滤件124所受的外力不足以抵推第二过滤件124移动时，洗涤水只能通过第一出水口1221再次进入洗衣机100的洗涤腔114内。
而当第二过滤件124所受的外力能够抵推第二过滤件124向远离第一过滤腔121的方向移动时，第二出水口1222被打开，第二过滤件124的侧壁封堵第一出水口1221，这样，洗涤水经第二出水口1222排出洗衣机100外。
上述方案中，当第二出水口1222被封堵，而第一出水口1221打开时，洗涤腔114内的水可经排水口1141进入第一过滤腔121内，以通过第一过滤件123对洗涤水中的粗线屑进行过滤，过滤后的洗涤水进入第二过滤腔122，通过第二过滤件124再次对洗涤水中的微线屑进行过滤，过滤后的洗涤水经第一出水口1221和回水口1142再次进入洗涤腔114内，这样，洗衣机100在洗涤运行时，例如，洗衣机100在主洗和漂洗阶段，洗涤水会在洗涤腔114、第一过滤腔121和第二过滤腔122内形成一个内循环，以使衣物在洗涤过程中，洗涤水被反复的进行过滤，以确保洗涤水中含有的微线屑极少，过滤效果好，减少微线屑对环境造成的污染。
而当洗涤结束后，在甩干或者排水阶段，第二过滤件124在外力作用下在第二过滤腔122内移动，以打开第二出水口1222，封堵第一出水口1221，以关闭洗涤水的内循环通道，在排水时，洗涤腔114内的洗涤水经第二出水口1222并通过洗衣机100的排水管130排出本体110外，不用经过第二过滤件124，这样，可以快速的排出洗涤水，能够提高排水效率，缩短整个洗涤周期。
由此可见，本申请实施例提供的洗衣机，能够提高对微线屑的过滤精度，减少微线屑对环境造成的污染；同时，能够提高排水效率，缩短洗衣机的整个洗涤周期。
需要说明的是，由于在洗涤过程中，洗涤水经过不断的循环过滤，因此，洗涤结束后，排放的洗涤水中含有的微线屑极少，从而减少了微线屑对环境的污染。
可选的，第一过滤件123可以是用于过滤粗线屑的滤芯，而第二过滤件124可以是用于过滤细线屑的滤芯，可以理解的是，第一过滤件123的过滤网孔大于第二过滤件124的过滤网孔，例如，第二过滤件124可以采用多层超高密度网孔的滤芯等，因此，第二过滤件124可过滤长度尺寸或者粒径尺寸较小的微线屑，以提高洗衣机100的过滤效果。
另外，在本申请中，排水过滤器120包括但不仅限于包括第一过滤件123和第二过滤件124，具体可根据实际需求设置多个过滤精度不同的过滤件，以进一步提高过滤效果，减少微线屑造成的环境污染。
可选的，第一过滤腔121和第二过滤腔122的连通处设置有驱动件125，驱动件125用于调节洗涤水的流速，以使洗涤水向第二过滤件124施加的外力作用的大小可调。
可以理解的是，第二过滤件124所受的外力作用可以是洗涤水在流动时对第二过滤件124施加的压力，其洗涤水向第二过滤件124施加的压力的大小会根据洗涤水的流速的变化而变化。
在一些实施例中，驱动件125可以为叶轮，其中，第一过滤腔121和第二过滤腔122之间可设置叶轮腔，即第一过滤腔121和第二过滤腔122之间通过叶轮腔连通，叶轮设置在叶轮腔中。
叶轮设置在第一过滤件123和第二过滤件124之间，叶轮的转速不同，则洗涤水向第二过滤件124施加的压力不同，当洗涤水向第二过滤件124施加的压力不足以推动第二过滤件124移动时，第二出水口1222被封堵，第一出水口1221打开，以使洗衣机100的内循环通道打开，排水通道关闭，这样，在洗涤过程中，通过第一过滤件123过滤洗涤水中较粗的线屑、布条等，可以防止粗线屑、布条等缠绕叶轮；通过第二过滤件124过滤洗涤水中的微线屑，从而实现减少洗涤水中微线屑的目的。
在上述方案中，可通过调节叶轮的运转功率的大小，以使叶轮的转速不同，以改变进入第二过滤腔122内洗涤水的流速，从而调节洗涤水向第二过滤件124施加的压力的大小。
例如，洗衣机100在洗涤时，可使叶轮以小功率运转，以使叶轮以较小的转速旋转，可以理解的是，叶轮以小功率运转时，其噪音小，能量消耗也少，第二过滤件124受到的洗涤水的压力相对较小，此时，洗涤水向第二过滤件124施加的压力不足以推动第二过滤件124移动，这样，洗涤腔114内的洗涤水流经第一过滤腔121和第二过滤腔122后由第一出水口1221再次返回至洗涤腔114内，以供继续洗涤内筒113中的衣物，而洗涤水分别经第一过滤件123和第二过滤件124的过滤，可以将洗涤水中的粗线屑和微线屑进行过滤，以使洗涤水中的微线屑数量极少。
而洗涤结束，进行甩干或排水时，可以使叶轮以大功率运转，以使叶轮以较大的速度旋转，此时，第二过滤件124受到的洗涤水的压力相对较大，以使洗涤水向第二过滤件124施加的压力足以推 动第二过滤件124移动，以使第二过滤件124封堵住第一出水口1221，而打开第二出水口1222，这样，洗衣机100中洗涤水的内循环通道被关闭，而排水通道被打开，洗涤水可流经第一过滤腔121和第二出水口1222快速的排出洗衣机100，提高排水效率，从而缩短洗衣机100的整体的洗涤周期。
可选的，排水过滤器120还包括弹性件126，弹性件126位于第二过滤腔122内，且弹性件126的一端与第二过滤件124背离第一过滤腔121的一端连接，弹性件126的另一端与第二过滤腔122背离第一过滤腔121的一端的腔壁连接；当叶轮以大功率运转，施加在第二过滤件124上的压力增大，第二过滤件124所受到的压力足以克服弹性件126的弹力时，推动弹性件126压缩，以使第二过滤件124向背离第一过滤腔121的一侧移动，从而打开第二出水口1222，封堵第一出水口1221，实现洗衣机100的正常排水；如图5和图6所示，第二过滤件124在向背离第一过滤腔121的一侧移动，当第二过滤件124的部分覆盖第一出水口1221时，排水压力大增，会加速第二过滤件124向背离第一过滤腔121的一侧移动，从而使第二出水口1222被打开，而第一出水口1221被封堵，实现洗衣机100正常的排水，能够保证排水时的高排水效率。
而当排水结束后，减少叶轮的运转功率，使洗涤水施加给第二过滤件124的压力小于弹性件126的弹力，这样，第二过滤件124在弹性件126的弹力作用下沿弹性件126的弹力方向移动，以使第二过滤件124复位，即第二过滤件124封堵第二出水口1222，打开第一出水口1221，从而实现关闭洗衣机100的排水通道，打开洗涤水的内循环通道，以使洗涤水在洗涤过程中通过内循环通道不断的进行过滤循环，以减少洗涤水中的微线屑数量，提高过滤效果，减少微线屑对环境的污染。
可选的，弹性件126可以为压缩弹簧。另外，弹性件126也可以是其他形状和结构，其具体形状和结构可以参照本领域技术人员常用的弹性件126的结构，此处不再赘述。
可选的，第二过滤件124与第二过滤腔122的腔壁之间设置有密封件127，以通过密封件127密封第二过滤件124与第二过滤腔122的腔壁之间的间隙，起到防水作用，以使洗涤水向第二过滤件124 施加冲击力时，洗涤水穿过第二过滤件124，不从第二过滤件124与第二过滤腔122的腔壁之间的缝隙通过，以确保过滤效果。
示例性的，密封件127为密封套，密封套套设在第二过滤件124上。
可选的，密封件127可以为橡胶等材质制成，具体不做限制。
可选的，第二过滤腔122背离第一过滤腔121的一端为敞口，敞口处设置有封堵敞口的第一舱盖128，第一舱盖128可拆卸连接在敞口处，且弹性件126背离第一过滤腔121的一端与第一舱盖128连接，而弹性件126的另一端与第二过滤件124连接，这样，将第一舱盖128、弹性件126和第二过滤件124连接在一起，打开第一舱盖128便可将第二过滤件124取出，以方便第二过滤件124的更换或清理。
在一些实施例中，第一过滤腔121背离第二过滤腔122的一端为开口，开口处设置有封堵开口的第二舱盖129，且第二舱盖129可拆卸的连接在开口处，且第一过滤件123与第二舱盖129连接，这样，当打开第二舱盖129时，便可取出第一过滤件123，以方便第一过滤件123的更换或清理。
可选的，第一过滤件123与第二舱盖129可设计为一体件，例如，第一过滤件123与第二舱盖129可通过粘接、焊接、卡接、可拆卸连接等方式形成为一体件，可以减少安装工序，降低安装成本。
另外，为了便于用户拆卸第一舱盖128和第二舱盖129，在本申请实施例中，如图1所示，第一舱盖128和第二舱盖129可安装在机壳111的正面，其中，机壳111的正面上分别设置有与机壳111的容纳空间连通的第一安装孔和第二安装孔，第一舱盖128可嵌设在第一安装孔内，第二舱盖129可嵌设在第二安装孔内，这样，用户可在机壳111的正面直接打开第一舱盖128和第二舱盖129，以对第二过滤件124和第一过滤件123进行更换或者清理，方便用户操作，提升用户体验感。
可以理解的是，洗衣机100的机壳111的正面指的是用户在操作洗衣机100时，面向用户的面为机壳111的正面，即洗衣机100的前面，洗衣机100的正面设置有洗衣机100的机门115，用户可打开机门115，将衣物放入内筒113内或从内筒113中取出。
可选的，为了使第一舱盖128和第二舱盖129均设置在机壳111的正面，在本申请实施例中，排水过滤器120可设置为如U型等结构的弯管结构，以方便用于拆装第一舱盖128和第二舱盖129，从而便于第二过滤件124和第二过滤件124的更换和清理。另外，排水过滤器120也可以设置为其他形状和结构，具体形状和结构可进行优化，只要便于用户更换和清理即可，在此，不做具体限制。
实施例二
图7为本申请实施例提供的洗衣机的控制方法的流程示意图。如图7所示，本申请实施例还提供一种洗衣机的控制方法，用于上述实施例中提供的洗衣机，其方法具体包括：
步骤S101：将洗涤腔内的洗涤水排至排水过滤器的第一过滤腔内，以对进入所述第一过滤腔内的洗涤水中的线屑进行过滤。
其中，第一过滤腔内设置有第一过滤件，例如，过滤网孔相对较大的滤芯，以用于过滤洗涤水中的粗线屑、布条等。
步骤S102：将所述第一过滤腔过滤后的洗涤水排至所述排水过滤器的第二过滤腔内，以对进入所述第二过滤腔内的洗涤水中的线屑进行过滤，其中，所述第二过滤腔的过滤精度大于所述第一过滤腔的过滤精度。
其中，第二过滤腔内设置有第二过滤件，第二过滤件可以是多层过滤网孔较密的滤芯，能够过滤洗涤水中的微线屑，从而减少洗涤水中微线屑的数量，提高过滤效果，减少微线屑造成的环境污染。
步骤S103：将所述第二过滤腔的第一出水口或第二出水口可选择性的打开，以使所述第二过滤腔内的洗涤水从所述第一出水口进入所述洗涤腔内或者从所述第二出水口排出本体外。
可以理解的是，当洗涤时，第一出水口一直处于打开状态，而第二出水口处于关闭状态，这样，洗涤水经由排水口进入排水过滤器中，当洗涤水经过过滤后再经由第一出水口和回水口再次回入洗涤腔内，这样，洗涤水经过不断的这样的内循环进行过滤，可以使洗涤水中的微线屑达到极少的目的；而当洗涤结束排水时，第一出水口被封堵，第二出水口被打开，这样，洗涤水经由排水口、第二出水口通过排水管排出洗衣机外，由于洗涤水在洗涤时已经过多次的循环过滤， 因此，洗涤水排出时，洗涤水中的微线屑的数量极少，从而可以减少微线屑对环境的污染。
另外，洗涤水在排出时，第一出水口为封堵状态，因此，洗涤水进入排水过滤器后直接从第二出水口排出，从而能够提高洗衣机的排水效率，减少洗衣机的洗涤周期。
本申请提供的洗衣机的控制方法及洗衣机。其中，本申请实施例提供的洗衣机包括本体，本体具有容纳洗涤水的洗涤腔，洗涤腔具有排水口和回水口；本体内还设置有排水过滤器，排水过滤器包括依次连通的第一过滤腔和第二过滤腔，第一过滤腔与排水口连通，第二过滤腔具有第一出水口和第二出水口，第一出水口与回水口连通，第二出水口与本体的排水管连通；第一过滤腔内设置有第一过滤件，用于过滤进入第一过滤腔内的线屑；第二过滤腔内设置有第二过滤件，用于过滤进入第二过滤腔内的线屑，其中，第一过滤件的过滤精度小于第二过滤件的过滤精度，且第二过滤件可在外力作用下在第二过滤腔内移动，以选择性的打开第一出水口和第二出水口中的一者，而封堵第一出水口和第二出水口中的另一者。通过上述方案，能够提高洗衣机的排水效率的同时，提高洗衣机对微线屑的过滤效果，减少微线屑造成的环境污染。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以通过具体情况理解上述术语在本申请中的具体含义。
在本公开的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或者位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或者暗示所指的装置或者元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
在本申请的说明书和权利要求书及上述附图说明中的术语“第一”、“第二”是用于区别类似的对象，而不必用于描述特定 的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。
此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或显示器不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或显示器固有的其它步骤或单元。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
