一种洗衣机的控制方法及洗衣机 技术领域
本发明属于洗衣机技术领域，具体地说，涉及一种洗衣机的控制方法及洗衣机。
背景技术
现有技术中，滚筒洗衣机的一般结构为在盛水筒的最低处设置盛水筒排水管，用于连接排水泵实现向外排水。所述盛水筒排水管一般为软管，具有一定容积，能够容纳一定量的水。滚筒洗衣机工作时，衣物处理剂被进水水流冲入外筒中，在未能充分溶解的情况下就会被冲入盛水筒排水管内部的空间中，在后续的洗衣过程中很难继续溶解与衣物接触，会在排水时随排水水流直接排走，造成浪费。
目前的滚筒洗衣机大多先向盛水筒内进一定量的水，使盛水筒排水管内充满水后再进行衣物处理剂的投放，从而减少未溶解的衣物处理剂在盛水筒排水管中的堆积。但对于颗粒状的洗衣粉等，由于其在短时间内无法充分溶解，还是会受重力作用下沉，导致部分未溶解的洗衣粉颗粒落入盛水筒排水管内。如此会导致洗衣过程中洗衣粉的实际浓度偏低，影响衣物的洗净效果。
申请号为201210497315.2的中国专利公开了一种带激荡水流的滚筒洗衣机控制方法，包括以下步骤：S10:检测洗衣机筒内的水位是否下降；S20:检测筒内带水衣物是否分布平衡，并判断偏心量；S30:内筒加速到第一预设转速，以大于正常洗涤转速的转速激荡水流，排水软管内的水和洗衣粉被带出、回流到洗衣机筒内；S40:重复执行N次步骤S30，排水软管内的水和洗衣粉被反复带出、回流，使洗衣粉充分均匀溶解到水中；S50:内筒以正常洗涤转速转动，开始洗涤。
然而上述方案中，通过控制内筒转动提高洗衣粉的溶解效果，但由于内筒中具有大量的水和衣物，需要检测偏心量，防止转动时出现较大振动。另一方面，内筒带动筒内衣物和水一同转动，由于整体质量过大，容易发生电机堵转的故障。
有鉴于此，特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种洗衣机的控制方法及洗衣机，洗衣机上设置带有过滤装置的循环过滤管路，在投放衣物处理剂后，可通过开启循环泵带动盛水筒中的水不断循环经过过滤装置，通过控制过滤装置中的过滤机构转动加强水流的搅动，进而可以使水中的衣物处理剂更快更充分地溶解，有利于提高衣物的洗净效果。
为解决上述技术问题，本发明采用技术方案的基本构思是：
一种洗衣机的控制方法，所述洗衣机包括：
盛水筒；
循环过滤管路，其进水端和出水端分别与盛水筒连通，其上设置循环泵和过滤装置；
所述过滤装置包括
过滤腔体，具有入水口和过滤水出口；

进一步地，所述过滤机构以第一设定转速持续转动达到预设时长，控制过滤机构停止转动。
进一步地，过滤机构停止转动后，循环泵保持开启状态，洗衣机进行循环过滤洗涤/漂洗。
进一步地，洗涤/漂洗结束，控制过滤机构以第二设定转速在过滤腔体内转动，清除过滤机构表面的过滤杂质；所述第一设定转速大于第二设定转速；
优选地，所述第一设定转速为100～800rpm。
进一步地，洗衣机根据当前运行的洗衣程序中的洗衣参数确定所述第一设定转速的取值；
优选地，所述洗涤参数包括盛水筒内的水温，和/或洗衣机是否开启加热功能；
更优地，所述第一设定转速的取值随盛水筒内的水温升高而减小；
和/或，所述第一设定转速的取值在洗衣机开启加热功能时减小。
进一步地，洗衣机根据当前运行的洗衣程序中的洗衣参数确定所述预设时长的取值；
优选地，所述洗涤参数包括盛水筒内的水位，和/或盛水筒内的水温，和/或洗衣机是否开启加热功能；
更优地，所述预设时长的取值随盛水筒内的水位升高而延长；
和/或，所述预设时长的取值随盛水筒内的水温升高而缩短；
和/或，所述预设时长的取值在洗衣机开启加热功能时缩短。
进一步地，所述开启循环泵之前还包括：盛水筒中的水位大于预设水位，则开启循环泵，否则等待盛水筒中的水位达到预设水位后开启循环泵。
进一步地，所述过滤装置还包括驱动机构，所述驱动机构与过滤机构连接，用于驱动过滤机构在过滤腔体中转动；
开启循环泵后，洗衣机根据当前运行的洗衣程序中的洗衣参数确定所述第一设定转速的取值；
开启驱动机构，驱动过滤机构以第一设定转速转动。
本发明的另一目的是提供一种洗衣机，采用上述所述的洗衣机的控制方法。
进一步地，所述过滤腔体内设置清洗颗粒，用于随水流运动摩擦碰撞，加快衣物处理剂的溶解。
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，过滤装置可在洗衣过程中对盛水筒中的水进行循环过滤，进而除去水中的线屑等过滤杂质，改善衣物的洗涤效果。在投放衣物处理剂后，开启循环泵向过滤装置输送盛水筒中的水，同时控制过滤机构转动，可以加强过滤装置内部的水流搅动，使其中的衣物处理剂更加充分均匀地溶解在水中，再输送回到盛水筒中，有利于加快衣物处理剂的溶解，提高衣物处理剂的利用率，从而提升洗衣效果。过滤装置一体可以实现两种不同功能，节省了对洗衣机内部空间的占用。
本发明中，洗衣机根据洗衣参数调节过滤机构的转动速度和转动时长，可以在当前的洗衣参数下，尽可能更快地完成衣物处理剂的充分溶解，进而可以保证洗衣机的工作效率，节省洗衣机的洗衣时长。
本发明中，洗衣机在盛水筒中水位达到预设水位后再控制循环泵开启，防止盛水筒中水量过少，循环泵内部吸入空气产生运行噪音。
本发明中，在过滤腔体内部设置清洗颗粒，清洗颗粒随水流运动，一方面可以在循环过滤过程中通过摩擦碰撞清洗过滤腔体内壁和过滤机构外壁，防止过滤杂质沉积造成的过滤装置堵塞，影响过滤效率，另一方面，溶解衣物处理剂的过程中也可以进一步加强过滤腔体中水流的搅动力度，进一步加快衣物处理剂的溶解效率。
下面结合附图对本发明的具体实施方式作进一步详细的描述。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或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发明和简化描述，而不是指示或暗示所指的装置或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发明的限制。

实施例一
如图1和2所示，本实施例所述的洗衣机包括：
盛水筒100；
循环过滤管路，其进水端和出水端分别与盛水筒100连通，其上设置循环泵400和过滤装置600。
本实施例中，过滤装置600设置在循环泵400的出水端与循环过滤管路的出水端之间，过滤装置600具体包括：
过滤腔体610，具有入水口6101和过滤水出口6102；
过滤机构620，可转动的设置在过滤腔体610内部，对进入过滤腔体610的水进行过滤。
具体地，盛水筒100上设置盛水筒排水管260与循环泵400的进水端连接，循环泵400的出水端连接排水管路210，排水管路210再连接循环管路220，循环管路220的出水端与过滤装置600的入水口6101连接。循环泵400开启时，盛水筒100中的水依次经过盛水筒排水 管260、循环泵400排水管路210和循环管路220进入过滤装置600中。
过滤装置600的过滤水出口6102用于排出过滤后的水，其通过回水管路230与盛水筒100连通，回水管路230具体连接在盛水筒100筒口处的窗垫110上。回水管路230上还设置控制回水管路230通断的回水控制阀231。
可以理解的是，还可以在盛水筒的筒壁上开设回水口，回水管路的出水端与所述回水口连接，直接向盛水筒中回水。
本实施例的洗衣机还包括用于连通外接水源与盛水筒的主进水管路，另一种方案中，回水管路的出水端还可以连接在所述主进水管路上，例如，连接在设置于主进水管路上的洗涤剂盒上，过滤后的水经洗涤剂盒回到盛水筒中。
详细地，过滤机构620将过滤腔体610内部分隔为外容腔与内容腔，其中入水口6101与所述外容腔连通，过滤水出口6102与内容腔连通。盛水筒100中的水在循环泵400的作用下经入水口6101进入外容腔中，通过过滤机构620进入内容腔实现过滤，水中携带的线屑附着在过滤机构620的外壁上。回水控制阀231为打开状态，过滤后的水最终从过滤水出口6102排出，经回水管路230回到盛水筒100中。
本实施例中，过滤装置600除了可以用于循环过滤之外，还能够辅助衣物处理剂的溶解过程。为此，如图3和图4所示，本实施例中洗衣机的控制方法包括：
向盛水筒100中投放衣物处理剂；
开启循环泵400，使盛水筒100中的水循环经过过滤装置600；
控制过滤机构620以第一设定转速在过滤腔体610内转动，溶解水中的衣物处理剂。
本实施例中所述的衣物处理剂包括但不限于用于洗涤阶段的洗衣粉、洗衣块或洗衣液，以及用于漂洗阶段的柔顺剂等。尤其是对于在水中溶解速度较慢的固体洗衣粉或洗衣块，其加速溶解的效果更加显著。
在衣物处理剂投入盛水筒100后，部分衣物处理剂可能沉入盛水筒排水管260内部空间，若直接开始洗涤或漂洗，这部分衣物处理剂无法在水中充分溶解，进而不能作用在所洗衣物上，影响洗衣效果。
本实施例中在投放衣物处理剂后开启循环泵400，且回水控制阀231为打开状态，使得沉入盛水筒排水管260内的衣物处理剂可以随水流循环重新回到盛水筒100中，有利于衣物处理剂更加充分均匀地在水中分散。同时，在循环过程中，过滤机构620在过滤腔体610内转动，对过滤腔体610内的水起到搅动作用，有利于在过滤腔体610内使衣物处理剂更加充分的溶解，然后再回到盛水筒100中，可以加快衣物处理剂的溶解，提高衣物处理剂的利用率，从而提升衣物的洗净效果。
本实施例的过滤装置600既可以用于洗衣机的循环过滤，又可以加快衣物处理剂在水中的溶解，通过同一结构实现两种不同功能，节省了对洗衣机内部空间的占用。另一方面，在过滤装置600长时间使用导致过滤效果变差后，仍可以提供加速溶解衣物处理剂的功能，避免过滤装置600无法起到任何作用而在洗衣机内部浪费空间。
需要说明的是，本实施例的控制方法还可以用于其他需要投放洗涤试剂的洗涤设备，如护理机、洗碗机等。
本实施例中，过滤装置600还包括驱动机构660，驱动机构660与过滤机构620连接，用于驱动过滤机构620在过滤腔体610中转动。在循环泵400开启后，通过开启驱动机构660并控制驱动机构660的工作参数，实现驱动过滤机构620以第一设定转速转动。
本实施例的进一步方案中，过滤机构620以第一设定转速持续转动达到预设时长，控制过滤机构620停止转动。
进一步地，过滤机构620停止转动后，循环泵400保持开启状态，洗衣机进行循环过滤洗涤/漂洗。
在上述方案中，所述预设时长为确保衣物处理剂充分溶解所需的时长，洗衣机控制过滤机构620的转动时长，也即驱动机构660的工作时长，在衣物处理剂充分溶解后即停止过滤机构620的转动。洗衣机进入洗涤/漂洗阶段，循环泵400保持开启状态，带动盛水筒100中的水循环经过过滤装置600进行过滤，过滤机构620在循环过滤过程中保持静止状态，有利于过滤后的水顺畅地排出。
详细地，盛水筒100内同轴设置滚筒120，用于盛放所洗衣物。过滤机构620停止转动后，洗衣机控制滚筒120以设定的转停比转动，进行洗衣洗涤/漂洗。
本实施例的具体方案中，洗衣机根据当前运行的洗衣程序中的洗衣参数确定所述预设时长的取值。
所述洗涤参数包括盛水筒100内的水位，和/或盛水筒100内的水温，和/或洗衣机是否开启加热功能。
详细地，所述预设时长的取值随盛水筒100内的水位升高而延长。水位越高，盛水筒100中的盛水量越大，而在水流循环流量一定的情况下，使盛水筒100内的水充分循环所需的时间越长。同时，更高的水位一般也对应更大的衣物处理剂投放量，因而使衣物处理剂充分溶解所需的时长也就更大。
所述预设时长的取值随盛水筒100内的水温升高而缩短，所述预设时长的取值在洗衣机开启加热功能时缩短。一般情况下，衣物处理剂在水中的溶解速率随水温的升高而加快，本实施例中，盛水筒100中的水温越高，转动时长的取值可以越短；以及，洗衣机开启加热功能时，转动时长的取值可以比不开启加热功能时更短。
在上述方案中，通过洗衣参数控制过滤机构620的转动时长取值，在保证水中衣物处理剂充分溶解的前提下，使溶解衣物处理剂的过程所经历的时长尽量较短，有助于缩短洗衣机一次洗衣程序的整体运行时长，提升用户体验。
本实施例中，洗衣机在洗涤/漂洗结束后执行自清理操作，包括：关闭回水控制阀231，控制过滤机构620以第二设定转速在过滤腔体610内转动，清除过滤机构620表面的过滤杂质。
具体地，驱动机构660开启驱动过滤机构620转动，使过滤机构620外壁附着的线屑等 过滤杂质在离心力作用下从过滤机构620外壁剥离。此时，由于回水控制阀231关闭，过滤腔体610内的水不从过滤水出口6102流出，转动的过滤机构620还可以搅动过滤腔体610内的水流，形成的激荡水流对过滤机构620外壁造成一定冲击力，也可以使线屑脱落。从过滤机构620表面剥离的线屑融入过滤腔体610内的水中。
其中，过滤机构620的第一设定转速大于第二设定转速。例如，所述第一设定转速为100～800rpm，所述第二设定转速为50～80rpm。
本实施例的进一步方案中，洗衣机根据当前运行的洗衣程序中的洗衣参数确定所述第一设定转速的取值。
具体地，所述第一设定转速的取值随盛水筒100内的水温升高而减小，所述第一设定转速的取值在洗衣机开启加热功能时减小。过滤机构620的转速越快，其搅动水流的力度越大，加速衣物处理剂溶解的效果越显著。由于衣物处理剂在水中的溶解速率随水温的升高而加快，本实施例中，盛水筒100中的水温越高，第一设定转速的取值可以越低；以及，洗衣机开启加热功能时，第一设定转速的取值可以比不开启加热功能时更低。
上述方案在保证衣物处理剂尽快溶解的前提下，避免过滤机构620以过高的转速转动，从而防止过滤机构620转速过高加快过滤装置600内部结构的磨损老化，导致过滤装置600的寿命缩短。
本实施例的进一步方案中，所述开启循环泵400之前还包括：盛水筒100中的水位大于预设水位，则开启循环泵400，否则等待盛水筒100中的水位达到预设水位后开启循环泵400。
衣物处理剂的投放一般在洗衣机的进水过程中进行，本实施例在洗衣机完成衣物处理剂的投放后再开启循环泵400。但由于此时洗衣机一般情况下并没有完成进水过程，盛水筒100中的实际水位还未达到设定的洗涤/漂洗水位。本实施例在开启循环泵400之前先对盛水筒100中的实际水位进行判断，只有在所述实际水位达到预设水位时才开启循环泵400，可防止盛水筒100中水量过少，循环泵400内部吸入空气产生运行噪音。
本实施例中，开启循环泵400后，洗衣机根据当前的运行的洗衣程序中的洗衣参数确定所述第一设定转速的取值，以及预设时长的取值；
开启驱动机构660，驱动过滤机构620以第一设定转速转动。
详细地，如图3所示，本实施例中洗衣机的控制方法包括如下步骤：
S1、投放衣物处理剂；
S2、衣物处理剂投放完成，开启循环泵；
S3、根据洗衣参数确定驱动机构的运行参数，包括第一设定转速的取值，以及预设时长的取值；
S4、开启驱动机构，驱动过滤机构以第一设定转速转动；
S5、达到预设时长，关闭驱动机构，过滤机构停止转动。
本实施例的洗衣机在需要投放衣物处理剂的进水阶段依次执行以上步骤S1至S5，在进 水完成后进行循环过滤洗涤/漂洗，包括执行循环过滤操作：循环泵400保持开启状态，回水控制阀231保持打开，盛水筒100中的水经过滤装置600过滤后重新回到盛水筒100中。
本实施例的另一种方案中，还可以在进水过程中执行步骤S1，进水完成后再依次执行步骤S2至S5。步骤S5执行结束后，洗衣机进行循环过滤洗涤/漂洗。
本实施例中，过滤装置600的过滤腔体610上还设置排污口6103，与过滤腔体610内的外容腔连通，用于向外排出线屑等过滤杂质。排污口6103连接排污管路240，排污管路240设置控制其通断的排污控制阀241。
洗涤/漂洗结束后，洗衣机执行自清理操作，将附着在过滤机构620上的线屑等过滤杂质除去，使线屑融入过滤腔体610内的水中。执行自清理操作时可以关闭循环泵400，并控制排污控制阀241保持关闭，使过滤腔体610内的水不流出。也可以控制循环泵400保持打开状态，并打开排污控制阀241，将盛水筒100中的水导入过滤装置600中对过滤机构620外壁进行冲刷清洗，再经排污口6103排出。
如图5和图6所示，自清理操作结束后，洗衣机还执行排污操作，包括：回水控制阀231关闭，排污控制阀241打开导通排污管路240，将过滤装置600中的携带线屑的污水经排污口6103排出。
通过上述过程，过滤装置600可以在洗衣机投放衣物处理剂后加速衣物处理剂的溶解过程，在洗涤/漂洗过程中对盛水筒100中的水进行循环过滤，除去水中的线屑，并在洗涤/漂洗结束后自主对附着的线屑进行清理并排出，从而可以进行下一次循环过滤操作。
本实施例的进一步方案中，洗衣机还包括回收装置500，与排污管路240的出水端连通，用于收集排出的线屑等过滤杂质501。
在上述方案中，通过设置回收装置500收集过滤装置600排出的过滤杂质501，使得过滤杂质501不会进入排水水流中，随排水水流排出洗衣机。通过以上方式避免了过滤杂质501中的细微线屑随水流排走，进入生态循环中，进而对生态环境及人体健康带来危害。
本实施例的具体方案中，回收装置500包括：
壳体510，内部具有回收腔室；
过滤组件520，设置在所述回收腔室内，将所述回收腔室分隔为第一腔室531和第二腔室532。
排污口6103与第一腔室531连通，携带过滤杂质501的污水进入第一腔室531，经过滤组件520过滤后进入第二腔室532，过滤杂质501收集于第一腔室531中。
具体地，过滤组件520可以为水平设置在回收腔室内一定高度处的框架及铺设在所述框架上的滤网。携带过滤杂质501的污水进入第一腔室531后，水可通过过滤组件520进入第二腔室532，过滤杂质501被滤网阻挡，残留在过滤组件520上表面。
在上述方案中，回收装置500中设置过滤组件520，用于对接收的污水进行过滤，将其中的过滤杂质501从水中分离出来。通过过滤组件520将回收装置500内部分隔为第一腔室 531和第二腔室532，污水中的过滤杂质501被过滤组件520阻挡，从而将过滤杂质501收集于第一腔室531中过滤组件520上表面，过滤后得到的清水收集于第二腔室532中。用户可直接对分离出的过滤杂质501进行收集处理，避免了过滤杂质501分散在水中，难以进行处理的情况。
本实施例中，所述洗衣机还包括箱体10，盛水筒100和过滤装置600均设置于箱体10内。壳体510可插入/抽出的设置在箱体10上，用户可将壳体510从箱体10内抽出，进而对其内部进行清理。
具体地，壳体510的上侧具有敞口，用户将壳体510从箱体10中抽出时，可通过壳体510上侧的敞口对附着在过滤组件520上表面的过滤杂质501进行清理。过滤组件520优选与壳体510可拆卸连接，用户可将过滤组件520从壳体510内部卸下并取出进行清理，操作更加方便。
本实施例的优选方案中，第二腔室532上设置出水口，用于排出过滤后的清水。通过在第二腔室532上设置出水口，可将进入第二腔室532的清水及时排出回收装置500，避免由过滤装置600排入的污水量较大时，回收装置500出现溢水现象。否则需要增加第二腔室532的容量，也即需要加大回收装置500的整体体积，导致其在洗衣机内部占用较大空间，不利于洗衣机整体体积的小型化。
另一方面，第二腔室532中的水可由出水口自动排出，用户对回收装置500进行清理时，只需要清理过滤组件520上的过滤杂质501，而无需手动倒出第二腔室532中的清水。当过滤组件520可拆卸地安装在壳体510中时，用户甚至不需要将壳体510从洗衣机的箱体10上完全取下，只需要取出过滤组件520进行清理即可，更方便操作。
本实施例的进一步方案中，排水管路210与循环管路220通过切换装置270导通，切换装置270还连接有外排管路250，可控制循环管路220和外排管路250择一与排水管路210导通。
具体地，切换装置270包括：
进水口，与排水管路210的出水端连接；
第一出水口，与循环管路220的进水端连接；
第二出水口，与外排管路250的进水端连接；
切换机构，控制第一出水口和第二出水口择一与所述进水口导通。
洗衣机通过过滤装置600溶解衣物处理剂，以及在执行循环过滤操作和自清理操作时，切换装置270导通排水管路210和循环管路220。自清理操作结束后，洗衣机执行排污操作，同时还控制切换装置270导通排水管路210和外排管路250，循环泵400为开启状态，将盛水筒100中剩余的水排出洗衣机。
通过切换装置270的设置，简化了洗衣机内部的管路连接结构。同时，循环泵400既可以用于循环过滤，又可以用于洗衣机排水，无需在洗衣机中设置两个实现不同功能的水泵，节省了空间，也降低了生产成本。
本实施例中，洗衣机中设置循环过滤管路及过滤装置600，循环泵400在洗衣机的洗涤及漂洗过程中可带动盛水筒100中的水循环经过过滤装置600，从而减少水中线屑的含量，能够改善洗衣效果。同时，过滤装置600还可以在衣物处理剂投放完成后通过过滤机构620的转动加快衣物处理剂的溶解，使投入盛水筒100中的衣物处理剂能够更加均匀且充分地溶解在水中，进一步提高洗衣效果。过滤装置600一体两用，节省了洗衣机内部的安装空间。
实施例二
如图1和图2所示，本实施例为上述实施例一的进一步限定，所述的过滤腔体610中还设置清洗颗粒680，用于随水流运动摩擦碰撞，加快衣物处理剂的溶解。
本实施例中，在过滤腔体610内设置清洗颗粒680，溶解衣物处理剂的过程中，过滤机构620转动搅动水流，同时清洗颗粒680随水流运动，相互之间发生摩擦碰撞，或与过滤腔体610内壁和过滤机构620外壁发生摩擦碰撞，可以进一步加强过滤腔体610中水流的搅动力度，从而进一步加快衣物处理剂的溶解速率。
另一方面，在循环过滤过程中，清洗颗粒680还可以通过摩擦碰撞清洗过滤腔体610内壁和过滤机构620外壁，防止过滤杂质在循环过滤过程中发生沉积，造成过滤装置600堵塞影响过滤效率。
本实施例中，清洗颗粒680的形状包括但不限于球形、椭球形、椭圆柱形等。清洗颗粒680的表面可以为光滑表面，也可以为非光滑表面。优选具有非光滑表面的清洗颗粒680，可以加大其与过滤腔体610内壁和过滤机构620外壁的摩擦力，剥离过滤杂质的效果更好。
清洗颗粒680的材质优选为耐磨弹性材料，避免清洗颗粒680在使用过程中轻易磨损。清洗颗粒680的回弹性优选为0％～50％，由受力时较容易发生形变的弹性材料制成清洗颗粒680，能够避免过滤机构620转动过程中与清洗颗粒680卡死，甚至导致过滤装置600损坏。
本实施例的进一步方案中，所述过滤腔体610中设置挡板690，挡板690左侧形成第一空间，挡板690右侧形成第二空间。入水口6101和清洗颗粒680设于挡板690的左侧，过滤水出口6102和排污口6103设于挡板690的右侧。
挡板690的具体结构如图7所示，其上设置若干过水孔691。如图1和图2所示，过水孔691连通第一空间与第二空间，但清洗颗粒680被挡板690限制于第一空间内，不会进入第二空间。如此避免了清洗颗粒680从过滤水出口6102或排污口6103随水流排出，或是堆积在过滤水出口6102或排污口6103处造成堵塞的情况。
具体地，挡板690的外周与过滤腔体610的内壁贴合或接近贴合设置，过水孔691的宽度为D 1，清洗颗粒680的宽度为d，且D 1＜d。
本实施例中的过水孔691为圆孔，过水孔691的宽度D 1即为过水孔691的直径大小。可以理解的是，过水孔691也可以设置为其他形状，如方孔、条形孔等，此时不同方向上过水孔691的最小尺寸即为宽度D 1。
类似地，对于球形的清洗颗粒680，所述清洗颗粒680的宽度d即为清洗颗粒680的直径。对于其他形状的清洗颗粒680，由于在不同方向上清洗颗粒680的尺寸不完全相同，多 个不同尺寸中最小的尺寸即为所述的宽度d。如此可以保证清洗颗粒680无论如何转变方向都无法通过挡板690上的过水孔691，进而保证了挡板690对清洗颗粒680的有效阻拦。
本实施例的进一步方案中，清洗颗粒680的密度小于水，水流进入过滤腔体610后，清洗颗粒680可以在水中上浮，进而更容易在水流的带动下在过滤腔体610的第一空间内运动，从而发生摩擦碰撞，加速衣物处理剂的均匀溶解，或者使过滤杂质脱落。如此避免了水流冲击力不足时，清洗颗粒680沉积在过滤腔体610底部，无法起到有效作用的情况。
本实施例的进一步方案中，过滤水出口6102的外周向过滤腔体610外部延伸形成密封支撑部611。
所述过滤机构620包括：
过滤部，与入水口6101设于挡板690的同一侧，对进入第一空间的水进行过滤；
出水接头621，左端与所述过滤部连接，右端穿过挡板690，且可转动的插设在密封支撑部611中。
挡板690上设置供出水接头621穿过的通孔692，通孔692与出水接头621的外壁间隙配合。
在上述方案中，出水接头621与密封支撑部611可转动的密封连接，过滤后的水经出水接头621流出。在挡板690上设置与出水接头621的外壁间隙配合的通孔692，出水接头621的外壁与通孔692的内壁不接触，防止过滤机构620转动时挡板690与出水接头621之间存在摩擦而产生阻力，影响过滤机构620的顺畅转动。
本实施例中，在过滤腔体610内部设置清洗颗粒680，可以在过滤机构620转动过程中随水流运动，从而进一步加强对水流的搅动力度，使衣物处理剂更快地溶解于水中。同时，在循环过滤过程中，清洗颗粒680可以随水流摩擦碰撞清洗过滤腔体610内壁和过滤机构620外壁，防止过滤杂质在过滤过程中发生沉积，保证了过滤效率，同时在过滤装置600进行自清理时也可以使过滤杂质更容易脱落。
实施例三
如图8和图9所示，本实施例为上述实施例一或二中过滤装置600的进一步限定，所述的过滤水出口6102的外周向过滤腔体610外部延伸形成密封支撑部611，过滤机构620一端具有插设在密封支撑部611中的出水接头621，出水接头621与密封支撑部611可转动的密封连接。
过滤装置600还包括：
第一轴承631，套设在出水接头621上；
第一密封件641，设置在第一轴承631朝向过滤腔体610内部的一侧，封堵出水接头621与密封支撑部611之间的间隙。
详细地，过滤机构620包括过滤网支架和过滤网625，其中，过滤网支架包括：
过滤网支撑部623，位于过滤腔体610内部，过滤网625覆盖在过滤网支撑部623表面；
出水接头621，设置在过滤网支撑部623左端；
转动支撑部622，设置在过滤网支撑部623右端，与过滤腔体610可转动的连接。
在上述方案中，出水接头621与密封支撑部611之间设置第一轴承631，对出水接头621进行支撑，使出水接头621在密封支撑部611内的转动更加顺畅，同时结构稳定，可以保证过滤机构620在过滤腔体610内的稳定转动。在第一轴承631的右侧设置第一密封件641，过滤腔体610内的洗涤水无法进入出水接头621与密封支撑部611之间的间隙，防止了第一轴承631与水接触，避免了第一轴承631失效，保证了第一轴承631的作用效果。同时，第一密封件641还防止了未经过滤的洗涤水从过滤水出口6102经密封支撑部611流出，影响过滤装置600对线屑的清除效率。
本实施例的具体方案中，第一密封件641套设在出水接头621上，第一密封件641的内壁与出水接头621的外壁密封连接，第一密封件641的外壁与密封支撑部611的内壁可转动的密封连接。
本实施例的进一步方案中，过滤装置600还包括第二密封件642，第二密封件642设置在第一轴承631背向过滤腔体610内部的一侧，封堵出水接头621与密封支撑部611之间的间隙。
具体地，第二密封件642套设在出水接头621上，第二密封件642的内壁与出水接头621的外壁密封连接，第二密封件642的外壁与密封支撑部611的内壁可转动的密封连接。
在上述方案中，第一轴承631的左侧还设置有第二密封件642，经出水接头621流出的水可以被第二密封件642阻挡，不会与第一轴承631接触。第一轴承631位于第一密封件641和第二密封件642之间，最大程度上保证了第一轴承631的安装环境无水，避免了第一轴承631遇水生锈，影响过滤机构620转动的顺畅性。
本实施例的进一步方案中，密封支撑部611的内壁具有阶梯结构，从密封支撑部611一端向过滤腔体610外部依次形成具有环形结构，且内径逐渐缩小的第一限位面601、第二限位面602和第三限位面603。
第一密封件641朝向过滤腔体610外侧的表面与第一限位面601抵接，第一轴承631朝向过滤腔体610外侧的表面与第二限位面602抵接，第二密封件642朝向过滤腔体610外侧的表面与第三限位面603抵接。
在上述方案中，通过阶梯结构的密封支撑部611内壁形成多个竖直的环形限位面，分别与第一密封件641、第一轴承631和第二密封件642各自的左侧表面抵接，可限制以上三者在出水接头621轴向上的移动，防止过滤机构620转动过程中，出水接头621与密封支撑部611之间的配合结构松动。
本实施例的优选方案中，出水接头621靠近过滤腔体610外部的一端的外径小于另一端的外径，在出水接头621的外壁上形成具有环形结构，且与出水接头621的轴线垂直的第四限位面604。第一轴承631朝向过滤腔体610内侧的表面与第四限位面604抵接。
通过设置出水接头621左端外径小于右端，在外径突变处形成朝向左侧的第四限位面 604，与第一轴承631的右侧表面抵接。如此，第一轴承631两侧均具有限位结构，结构更加稳定。
本实施例中，密封支撑部611远离过滤腔体610的一端，也即密封支撑部611的左端连接过滤腔法兰650，过滤腔法兰650中部具有与出水接头621连通的贯通口653。贯通口653的外周背向密封支撑部611延伸形成连接部651。
优选地，过滤腔法兰650朝向密封支撑部611一侧的表面具有凸起的插接部652，插接部652插设在密封支撑部611左端的开口内。
在上述方案中，密封支撑部611左端连接过滤腔法兰650，并在过滤腔法兰650上形成连接部651，连接部651的外径小于密封支撑部611的外径，连接部651的内径优选等于出水接头621的内径。过滤装置600安装于洗衣机中时，通过连接部651与回水管路连接，相较于回水管路直接连接在密封支撑部611左端的方式，安装更加容易。
过滤腔法兰650右侧具有插入密封支撑部611左端开口的插接部652，便于过滤腔法兰650与密封支撑部611装配时的定位。过滤腔法兰650和密封支撑部611外周分别设置若干固定部，通过螺钉穿过所述固定部，实现过滤腔法兰650和密封支撑部611的固定。
本实施例的进一步方案中，密封支撑部611的外壁设置沿密封支撑部611的径向延伸的加强筋613，加强筋613与过滤腔体610上过滤水出口6102所在的表面连接。
由于密封支撑部611从过滤腔体610的左侧端面伸出一定长度，加强筋613的设置从外部对其周侧壁进行支撑，保证了密封支撑部611的强度。
本实施例的进一步方案中，过滤机构620右端的转动支撑部622沿其转动轴线向过滤腔体610外部延伸，过滤腔体610上设置供转动支撑部622穿过的安装口6104。转动支撑部622与安装口6104可转动的密封连接。
转动支撑部622用于连接驱动过滤机构620转动的驱动机构，转动支撑部622从过滤腔体610右端伸出，并在转动支撑部622的右端设置电机安装部624，用于与驱动机构连接，从而可以将驱动机构设置在过滤腔体610外部，避免与水接触。
进一步地，安装口6104的外周沿转动支撑部622的轴线向过滤腔体610外延伸形成套筒部612，转动支撑部622上套设第三密封件643。第三密封件643的内壁与转动支撑部622的外壁密封连接，第三密封件643的外壁与套筒部612的内壁可转动的密封连接。
套筒部612与转动支撑部622之间还设置第二轴承632，第二轴承632套设在转动支撑部622上，位于第三密封件643朝向过滤腔体610外部的一侧。
在上述方案中，第三密封件643的设置防止过滤腔体610内的水从安装口6104漏出，第二轴承632的设置可以对转动支撑部622起到支撑作用，保证转动支撑部622与套筒部612的相对转动更加顺畅。第二轴承632设置在第三密封件643的右侧，不与过滤腔体610内的水接触，避免失效。
本实施例的优选方案中，套筒部612靠近过滤腔体610外部的一端的内径小于另一端的内径，在套筒部612的内壁上形成具有环形结构，且与转动支撑部622的轴线垂直的第五限 位面605。第三密封件643朝向过滤腔体610外侧的表面与第五限位面605抵接。
转动支撑部622靠近过滤腔体610外部的一端的外径小于另一端的外径，在转动支撑部622的外壁上形成具有环形结构，且与转动支撑部622的轴线垂直的第六限位面606。第二轴承632朝向过滤腔体610内侧的表面与第六限位面606抵接。
在上述方案中，套筒部612右端的内径小于左端的内径，在其内径突变处形成朝向左侧的第五限位面605，与第三密封件643的右侧表面抵接。转动支撑部622右端的外径小于左端的外径，其外径突变处形成朝向右侧的第六限位面606，与第二轴承632的左侧表面抵接。以上结构限制了第三密封件643和第二轴承632在转动支撑部622轴向上的移动，结构稳定。
进一步地，过滤网支撑部623中部区域的横截面积一定，其左右两端具有锥形结构，使过滤网625的局部表面倾斜设置，有利于附着线屑的脱落。
本实施例中，过滤机构620两端分别设有第一轴承631与第二轴承632进行支撑，保证了过滤机构620在过滤腔体610内顺畅且稳定地转动。同时通过第一密封件641、第二密封件642和第三密封件643的设置，最大程度的保证了第一轴承631和第二轴承632的安装环境无水，防止了第一轴承631和第二轴承632与水接触，避免了两者的失效。
实施例四
如图1和图2所示，本实施例提供一种洗衣机的控制方法，本实施例中洗衣机的结构与上述实施例一中的洗衣机相同。
具体地，所述的控制方法包括：
开启循环泵400，导通循环过滤管路，洗衣机进行循环过滤漂洗；
漂洗结束，关闭循环泵400；
开启驱动机构660，带动过滤机构620在过滤腔体610内转动；
达到第一设定条件，开启循环泵400，同时打开排污控制阀241导通排污管路240；
达到第二设定条件，切断循环过滤管路。
优选地，达到第一设定条件后，驱动机构660保持开启状态，带动过滤机构620持续转动。
本实施例中，所述的导通循环过滤管路包括：切换装置270导通过滤装置600和循环泵400的出水端，打开回水控制阀231导通回水管路230。所述的切断循环过滤管路包括：切换装置270导通外排管路250和循环泵400的出水端。
可以理解的是，所述的切断循环过滤管路也可以通过关闭循环泵400实现。
本实施例中，过滤装置600的入水口6101高于洗衣机的最高水位高度，洗衣机在漂洗过程中对漂洗水进行循环过滤，过滤装置600及循环过滤管路中始终充满漂洗水。
漂洗结束关闭循环泵400后，由于排水管路210由下至上输送水流，循环管路220和过滤装置600高于盛水筒100设置，排水管路210和循环管路220中的水在重力作用下向下回 流，最多可回流至排水管路210中水面高度与盛水筒100中水位高度平齐，水面以上直至过滤装置600之间的管路中充满空气。但过滤装置600低于循环管路220，其中的水不会经循环管路220回流。关闭循环泵400的同时也关闭回水控制阀231，且此时排污控制阀241为关闭状态，过滤装置600内部的水留存在过滤腔体610内，不会向外排出。
驱动机构660开启后，带动过滤机构620高速转动，使表面附着的线屑等过滤杂质在离心力作用下从过滤机构620表面剥离。此时，由于回水控制阀231与排污控制阀241均为关闭状态，过滤腔体610内的水不流出，高速转动的过滤机构620还可以搅动过滤腔体610内的水流，形成的激荡水流对过滤机构620表面造成一定冲击力，同时还带动清洗颗粒680运动以摩擦碰撞过滤腔体610内壁和过滤机构620外壁，进一步加强线屑的脱落。从过滤机构620表面剥离的线屑等过滤杂质融入过滤腔体610内的水中。
开启循环泵400的同时，也打开排污控制阀241，使排污管路240导通，过滤装置600内的污水可以从排污口6103排出，清洗颗粒680被挡板690阻拦留在过滤腔体610内部。循环泵400的开启将排水管路210和循环管路220中的空气压入过滤装置600，进而使过滤装置600中携带线屑的污水在空气压力下由排污口6103完全排出，避免过滤装置600中存在污水残留，对过滤装置600的清理效果好。排污控制阀241在循环泵400开启的同时打开，保证了空气通入过滤装置600中时所产生的压力，进而可确保过滤装置600中的污水充分排出。
为避免过滤装置600中的污水排净后，盛水筒100中的水又经过循环管路220进入过滤装置600，洗衣机预设有第二设定条件，当达到第二设定条件时，切断循环过滤管路，停止盛水筒100中的水向过滤装置600输送。
本实施例的具体方案中，所述第一设定条件可以为循环泵400关闭达到第一设定时间t 1，所述第二设定条件可以为循环泵400开启达到第二设定时间t 2。
在上述方案中，第一设定时间t 1和第二设定时间t 2的具体取值可以预先通过大量实验得出并直接写入洗衣机的控制程序中。
具体地，第一设定时间t 1的取值约为排水管路210中水位高度开始下降直至停止所需的最大时长，第二设定时间t 2的取值约为排水管路210中水位在循环泵400开启后上升至接近排水管路210顶端所需的最短时长。如此，可以保证循环泵400关闭期间，管路中能够进入更大量的空气，同时，有效避免循环泵400开启后再有水进入过滤装置600的情况。
本实施例的另一种方案中，还可以采用水位高度作为第一设定条件和第二设定条件。具体地，所述第一设定条件为：循环泵400与过滤装置600之间的管路中，水位达到第一设定值H 1。所述第二设定条件为：循环泵400与过滤装置600之间的管路中，水位达到第二设定值H 2。其中，H 1<H 2。
在本实施例中，上述水位具体为排水管路210中的水位高度，洗衣机的排水管路210中可以设置水位检测装置，以实现对排水管路210中水位的检测。
在上述方案中，第一设定值H 1的取值大于且尽量接近洗衣机的最高水位高度，以保证循环泵400关闭后，排水管路210中的水位可以下降达到第一设定值H 1。
从洗衣机接收到排水管路210中的水位上升至第二设定值H 2的信号，直至切换装置270导通排水管路210与外排管路250之间一般具有一定时间差。为避免响应延迟造成循环泵400开启后又有水进入过滤装置600，第二设定值H 2的取值与排水管路210的顶端所对应的水位高度之间需要具有一定差值ΔH。所述差值ΔH的具体取值可通过预先进行的大量实验得出，从而保证洗衣机接收到水位达到第二设定值H 2的信号后，具有足够的响应时间控制切换装置270完成水路的切换。
本实施例的进一步方案中，洗衣机判断当前运行进程为本次洗衣程序中最后一次漂洗阶段，则在漂洗结束后关闭循环泵400，并在达到第一设定条件后开启循环泵400。
洗衣机判断当前运行进程不是本次洗衣程序中最后一次漂洗阶段，则在漂洗结束后执行以下操作：
循环泵400保持运行状态；
达到第三设定条件，切断循环过滤管路。
在上述方案中，对于中间漂洗阶段，由于洗衣机之后还需要继续运行，也即还会有漂洗水循环经过过滤装置600进行过滤，此时可以不将过滤装置600中携带有线屑的污水排净，只需将过滤机构620表面附着的线屑除去即可。
在漂洗结束后，回水控制阀231关闭，排污控制阀241打开，循环泵400保持运行状态，盛水筒100中的水继续在循环泵400的作用下向过滤装置600输送，对过滤装置600内部进行冲洗，冲洗后的污水经排污口6103排入排污管路240。
本实施例中，所述第三设定条件可以为漂洗结束达到第三预设时间t 3，其取值预先通过实验获得并写入控制程序中，保证可以将过滤机构620表面附着的线屑基本除去。
或者，也可以在盛水筒100中水位下降达到预设值ΔH 1时切断循环过滤管路，也即控制切换装置270导通排水管路210与外排管路250，循环泵400继续运行，将盛水筒100中剩余的水排出洗衣机。
本实施例的优选方案中，中间漂洗结束后，开启驱动机构660，带动过滤机构620在过滤腔体610内高速转动，可搅动过滤腔体610内的水，使附着的线屑在离心力和激荡水流的双重作用下，从过滤机构620表面剥离，融入过滤腔体610内的水中，再由排污口6103排出过滤腔体610，线屑的清理效率高。
本实施例中，洗衣机仅在最后一次漂洗结束时执行先关闭循环泵400，然后再开启循环泵400的操作，以将过滤装置600中的污水完全排净。而在中间漂洗结束时，循环泵400保持运行状态，避免了循环泵400在洗衣机运行过程中频繁开启关闭，影响其使用寿命。
本实施例中，洗衣机在洗涤结束后也对过滤装置600进行清理，具体控制方法如下：
开启循环泵400，切换装置270导通循环泵400出水端与过滤装置600，回水控制阀231打开，洗衣机进行循环过滤洗涤；
洗涤结束，循环泵400保持运行状态，关闭回水控制阀231，打开排污控制阀241；
达到第四设定条件，切换装置270导通循环泵400出水端与外排管路250。
其中，所述的第四设定条件可以为洗涤结束达到第四预设时间t 4，也可以为盛水筒100中水位下降高度达到预设值ΔH 2。
由于洗涤结束后，在洗衣程序的后续过程中还需进行循环过滤漂洗，与中间漂洗类似，也不需要将过滤装置600中的污水完全排出，循环泵400可以保持运行状态，不需要关闭。
本实施例中，洗衣机在洗涤及中间漂洗结束后，控制循环泵400保持运行状态，将盛水筒100中的水输送至过滤装置600进行冲洗，冲洗后的污水从过滤装置600的排污口6103排出。最后一次漂洗结束后，先关闭循环泵400，等待管路中进入空气，再重新开启循环泵400，将管路中空气压入过滤装置600，从而将其中的污水完全排净，保证洗衣机停止运行后过滤装置600内无污水残留，可有效避免细菌滋生。同时，洗衣机仅在最后一次漂洗结束后执行先关闭循环泵400并再开启的操作，减少了循环泵400不必要的开启关闭操作，延长了循环泵400的使用寿命。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
