Description

过滤装置及洗衣机 技术领域
本发明涉及一种过滤装置和包括该过滤装置的洗衣机。
背景技术
一般的洗衣机包括：洗涤桶，能蓄水并收容洗涤物；以及过滤装置，配置于洗涤桶内并从洗涤桶内的水中捕获异物。图1中示出了用于洗衣机的现有的过滤装置1。过滤装置1包括：纵向上长的基座2，在洗衣机中装配于收容洗涤物并能蓄水的洗涤桶的内周部；过滤器3，与基座2对置配置并向洗涤桶内露出；以及壳体4，配置于基座2与过滤器3之间。
如图2所示，基座2中的向洗涤桶内露出的表面部2A在上端部设有上开口2B，在下端部设有下开口2C。在表面部2A中的上开口2B与下开口2C之间的中间区域2D的中央，设有左右一对水流板5和隔着这一对水流板5的左右一对流入区域2E。各水流板5经由沿上下方向延伸的转动轴6装配于基座2，能绕转动轴6转动。将右侧的水流板5称为第一水流板5A，将左侧的水流板5称为第二水流板5B。在各流入区域2E，以沿上下方向排列的方式设有多个上下方向上薄的板状的引导件2F。将右侧的流入区域2E称为第一流入区域2EA，将左侧的流入区域2E称为第二流入区域2EB。
如图3所示，过滤器3呈纵向上长的板状。在过滤器3中的与基座2对置的背面部3A中，上凸部3B设于上端部，向基座2侧突出的下凸部3C设于下端部，向基座2侧突出的多个加强肋3D分散设置于上凸部3B与下凸部3C之间。在过滤器3中的上凸部3B与下凸部3C之间，以呈横向排列的三列的方式设有沿上下方向延伸的三个捕获区域3E。将图3中的左端的捕获区域3E称为第一捕获区域3EA，将图3中的右端的捕获区域3E称为第二捕获区域3EB，将正中的捕获区域3E称为第三捕获区域3EC。在各捕获区域3E中的避开加强肋3D的位置，设有沿上下方向等间隔排列的多个贯通孔3F，在各贯通孔3F，以 堵住贯通孔3F的方式装配有网片8。在网片8形成有无数个作为微小的贯通孔的过滤孔8A。需要说明的是，上述的图1中省略了网片8的图示。
壳体4呈长方形的板状。在壳体4的中央设有贯通壳体4并沿壳体4的长尺寸方向延伸的中继口4A。在图3中的姿势下的壳体4的上表面部设有隔着中继口4A沿壳体4的长尺寸方向延伸的呈槽状的一对收容室4B。将图3中的左侧的收容室4B称为第一收容室4BA，将图3中的右侧的收容室4B称为第二收容室4BB。在壳体4中设有：第一边界肋4CA，作为中继口4A与第一收容室4BA的边界沿壳体4的长尺寸方向延伸；以及第二边界肋4CB，作为中继口4A与第二收容室4BB的边界沿壳体4的长尺寸方向延伸。
壳体4中的长尺寸方向上的端部经由转动轴9与过滤器3连结。因此，当使图3的状态下的过滤器3和壳体4中的一方绕转动轴9转动而接近另一方时，如图4所示，过滤器3和壳体4组合而过滤单元10完成。当将完成的过滤单元10组装于基座2并将过滤器3的上凸部3B和下凸部3C(参照图3)分别嵌入于基座2的上开口2B和下开口2C(参照图2)时，图1所示的过滤装置1完成。
如作为图1的A-A向视剖视图的图5所示，在完成的过滤装置1中，基座2的第一流入区域2EA、过滤器3的第一捕获区域3EA以及壳体4的第一收容室4BA在左右方向上配置于相同的位置，第一收容室4BA与第一捕获区域3EA对置。此外，基座2的第二流入区域2EB、过滤器3的第二捕获区域3EB以及壳体4的第二收容室4BB在左右方向上配置于相同的位置，第二收容室4BB与第二捕获区域3EB对置。另一方面，过滤器3的第三捕获区域3EC从壳体4的中继口4A向基座2侧露出。
当装配有过滤装置1的洗涤桶内产生水流时，洗涤桶内的水会流入第一流入区域2EA或流入第二流入区域2EB。如箭头P所示，流入至第一流入区域2EA的水使第一水流板5A向第二水流板5B侧转动并且将第二水流板5B按压于第二边界肋4CB。于是，该水通过第二水流板5B而与第二流入区域2EB隔绝，由此该水毫无遗漏地穿过中继口4A并经过第一捕获区域3EA、第二捕获区域3EB以及第三捕获区域3EC中的任一方的网片8的过滤孔8A而流出。相反，流入至第二流入区域2EB的水使第二水流板5B向第一水流板5A侧转动并且将第一水流板5A按压于第一边界肋4CA，由此该水毫无遗漏地穿过中继口4A， 然后经过任意的捕获区域3E中的网片8的过滤孔8A而流出(未图示)。无论如何，流出的水中所含的线屑等异物F都会在捕获区域3E被捕获。
过滤装置1由基座2、过滤器3、壳体4以及一对水流板5这五个部件构成，但始终期望减少部件个数。此外，在过滤装置1中，过滤器3的加强肋3D与壳体4接触，由此确保了过滤单元10的强度，因此能抑制洗涤物接触时的过滤单元10的变形，但过滤装置1整体的强度有改善的余地。
并且，当随着洗涤桶的旋转而产生离心力时，过滤装置1中，在第一捕获区域3EA捕获到的异物F收容于壳体4中的与第一捕获区域3EA对置的第一收容室4BA，在第二捕获区域3EB捕获到的异物F收容于壳体4中的与第二捕获区域3EB对置的第二收容室4BB。但是，在壳体4中，中继口4A与第三捕获区域3EC对置，因此在第三捕获区域3EC捕获到的异物F恐怕不会被任何收容室4B容受，而是经过中继口4A泄漏至过滤装置1外。因此，在过滤装置1中，异物的捕获效率也有改善的余地。而且，当作为可动部件的水流板5破损或脱落时，水流板5会妨碍水流等，由此异物的捕获效率恐怕会下降。
发明内容
发明所要解决的问题
本发明在上述背景下完成，其目的在于提供一种能以较少的部件个数谋求提高强度和异物捕获效率的过滤装置和包括该过滤装置的洗衣机。
用于解决问题的方案
本发明是一种过滤装置，其包括：基座，在洗衣机中装配于收容洗涤物并能蓄水的洗涤桶的内周部，所述基座设有表面部、第一肋以及第一流入区域和第二流入区域，所述表面部面向所述洗涤桶内，所述第一肋配置于所述表面部，所述第一流入区域和第二流入区域以隔着所述第一肋横向排列的方式配置于所述表面部；过滤器，与所述基座对置配置并向所述洗涤桶内露出，所述过滤器设有第二肋、第一捕获区域和第二捕获区域以及多个过滤孔，所述第二肋向所述第一肋侧突出，所述第一捕获区域和第二捕获区域以隔着所述第二肋横向排列的方式配置，所述多个过滤孔分别分布于所述第一捕获区域和第二捕获区域； 以及壳体，配置于所述基座与所述过滤器之间，所述壳体设有第一中继口、第二中继口以及第三肋，所述第一中继口对所述第一流入区域与所述第一捕获区域之间进行中继，所述第二中继口对所述第二流入区域与所述第二捕获区域之间进行中继，并以与所述第一中继口横向排列的方式配置，所述第三肋配置于所述第一中继口与所述第二中继口之间，被所述第一肋和所述第二肋包夹，所述过滤装置在所述第一捕获区域捕获在所述洗涤桶内流入所述第一流入区域并经过所述第一中继口而从所述第一捕获区域的所述过滤孔流出的水中所含的异物，在所述第二捕获区域捕获在所述洗涤桶内流入所述第二流入区域并经过所述第二中继口而从所述第二捕获区域的所述过滤孔流出的水中所含的异物。
此外，本发明的特征在于，在所述壳体设有：第一收容室，从所述第一捕获区域向所述基座侧凹陷来容受来自所述第一捕获区域的异物；以及第二收容室，从所述第二捕获区域向所述基座侧凹陷来容受来自所述第二捕获区域的异物。
此外，本发明的特征在于，所述过滤器和所述壳体经由转动轴连结，所述壳体能在所述第三肋接触所述第二肋的组装位置与所述第三肋远离所述第二肋的分解位置之间相对于所述过滤器绕所述转动轴进行相对转动，所述壳体位于组装位置时的所述过滤器和所述壳体构成完成的过滤单元，能拆装于所述基座。
此外，本发明是一种洗衣机，包括：洗涤桶，收容洗涤物并能蓄水；以及所述过滤装置，装配于所述洗涤桶的内周部。
发明效果
根据本发明，过滤装置以基座、过滤器以及壳体这三个较少的部件个数构成。在过滤装置中，基座与过滤器之间的壳体的第三肋被基座的第一肋和过滤器的第二肋包夹，由此这些肋被一体化而构成分隔壁来加强整个过滤装置，因此能谋求提高强度。
基座的第一流入区域、过滤器的第一捕获区域以及壳体的第一中继口构成过滤装置的第一内部空间，基座的第二流入区域、过滤器的第二捕获区域以及壳体的第二中继口构成过滤装置的第二内部空间，第一内部空间和第二内部空间隔着由一体化的第一肋、第二肋以及第三肋构成的分隔壁以横向排列的方式 配置。在过滤装置装配于洗衣机的洗涤桶的内周部的状态下，当洗涤桶内产生沿其内周部的第一周向的水流时，洗涤桶内的水会流入第一流入区域并经过第一中继口从第一捕获区域的过滤孔流出，该水中所含的异物会在第一捕获区域被捕获。当洗涤桶内产生与第一周向相反的第二周向的水流时，洗涤桶内的水会流入第二流入区域并经过第二中继口从第二捕获区域的过滤孔流出，该水中所含的异物会在第二捕获区域被捕获。如此，将过滤装置的内部空间二分为第一内部空间和第二内部空间并去除可动部件，根据洗涤桶内的水流的方向，在第一内部空间和第二内部空间中的某一方毫无遗漏地捕获异物，由此过滤装置能以稳定的状态捕获异物，因此能谋求提高异物捕获效率。
此外，根据本发明，在因洗涤桶的旋转而产生了离心力的情况下，在壳体中，第一收容室容受来自第一捕获区域的异物，第二收容室容受来自第二捕获区域的异物。由此，能防止过滤装置好不容易捕获到的异物泄漏至过滤装置外，因此能谋求进一步提高异物捕获效率。
此外，根据本发明，能使由过滤器和壳体构成的过滤单元拆装于基座，因此，使用者只需将过滤单元从基座拆下并分解就能去除由过滤装置捕获到的异物以进行维护。然后，使用者通过完成过滤单元并将其装配于基座就能使过滤装置恢复至可使用状态。

具体实施方式
以下，参照附图对本发明的实施方式进行具体说明。图6是本发明的一个实施方式的洗衣机11的示意性纵剖视图。首先，以图6中的上下方向Z为基准对洗衣机11的概要进行说明。上下方向Z当中，将上侧称为上侧Z1，下侧称为下侧Z2。洗衣机11包括：箱体12，形成为箱状；水桶13，能蓄水；洗涤桶14，收容洗涤物L；马达15；以及波轮16和过滤装置17，配置于洗涤桶14内。需要说明的是，洗衣机11也包括具有洗涤物L的烘干功能的洗干一体机。
在箱体12的上表面设有：开口部12A；以及门18，对开口部12A进行开闭。水桶13例如为树脂制，形成为有底圆筒状。水桶13一体具有：大致圆筒状的圆周壁13B，在其上端具有开口部13A；以及圆板状的底壁13C，从下侧Z2堵住圆周壁13B的中空部分。开口部13A由与圆周壁13B连结的罩19开闭。在水桶13的上部连接有供水路20，水桶13内蓄有从供水路20供给的自来水、洗澡水以及溶解有洗涤剂的液体等水。在供水路20的中途设有对供水路20进行开闭的供水阀21。水桶13内的水经过与底壁13C连接的排水路22而排出至机外即箱体12外。在排水路22的中途设有对排水路22进行开闭的排水阀23。
洗涤桶14例如为金属制，形成为比水桶13小一圈的有底圆筒状。洗涤桶14一体具有：大致圆筒状的圆周壁14B，在其上端具有出入口14A；以及圆板 状的底壁14C，从下侧Z2堵住圆周壁14B的中空部分。在本实施方式中，经过洗涤桶14的圆心的轴线J沿上下方向Z垂直延伸。因此，洗衣机11是纵向配置有洗涤桶14的立式全自动洗衣机。需要说明的是，也可以是，轴线J分别相对于上下方向Z和水平方向H倾斜延伸，由此洗涤桶14倾斜配置。
本实施方式的洗涤桶14收容于水桶13内，能以轴线J为中心进行旋转。洗涤桶14的旋转方向与水桶13和洗涤桶14各自的周向S一致。以下，将以轴线J为基准的径向称为径向R，径向R当中，将靠近轴线J的方向称为径向内侧R1，将远离轴线J的方向称为径向外侧R2。
出入口14A从下侧Z2与开口部13A连通，开口部13A和出入口14A由罩19一并开闭。洗衣机11的使用者在打开门18和罩19时，能经由开放的开口部12A、开口部13A以及出入口14A将洗涤物L取出放入于洗涤桶14内。在圆周壁14B和底壁14C中的至少任一方形成有贯通孔14D，因此水桶13内的水能经由贯通孔14D在水桶13与洗涤桶14之间往来。因此，在洗涤桶14内也能蓄水，水桶13的水位与洗涤桶14的水位一致。在洗衣机11的脱水运转中，在排水阀23打开的状态下洗涤桶14旋转。于是，洗涤桶14内的洗涤物L内的水分通过离心力而渗出，经过贯通孔14D和排水路22而排出至机外。在圆周壁14B的上端部同轴地装配有收容了液体的中空的平衡环24，该平衡环24用于保持洗涤桶14的旋转平衡。
马达15配置于水桶13的底壁13C的下侧Z2。马达15的输出轴分支为：管状的第一输出轴15A，沿轴线J向上侧Z1延伸；以及第二输出轴15B，以具有游隙的方式插通于第一输出轴15A的内部空间。马达15能从第一输出轴15A和第二输出轴15B中的某一方或双方输出转矩。需要说明的是，马达15的输出轴中也可以装入将马达15的转矩的输出目标切换为第一输出轴15A和第二输出轴15B的离合器(未图示)。
第一输出轴15A向上侧Z1延伸并贯通底壁13C的中心部。第一输出轴15A具有在底壁13C与底壁14C之间呈凸缘状突出的凸缘部15C，凸缘部15C固定于底壁14C，由此该第一输出轴15A与洗涤桶14连结。当马达15被驱动而转矩转递至第一输出轴15A时，洗涤桶14旋转。
波轮16为沿水平方向H配置在洗涤桶14的底壁14C上的圆盘。波轮16 的周向与上述的周向S一致，波轮16的径向与上述的径向R一致。在波轮16的上表面，以沿周向S排列的方式设有多个沿径向R并且向上侧Z1隆起的筋状的凸部16A。
马达15的第二输出轴15B中的向凸缘部15C的上侧Z1伸出的上端部贯通洗涤桶14的底壁14C的圆心部而装配于波轮16的圆心部。当马达15被驱动而转矩传递至第二输出轴15B时，波轮16绕轴线J旋转。此时，洗涤桶14处于停止状态。在洗衣机11中的清洗运转、漂洗运转时，洗涤桶14内的洗涤物L被沿周向S旋转的波轮16的凸部16A搅拌。由此，洗涤桶14内主要产生沿周向S的水流。需要说明的是，也可以使洗涤桶14与波轮16一起旋转，由此能朝向周向S产生流动得更强劲的水流。
在洗涤桶14内，详细而言是在构成圆周壁14B的内周面的内周部14E设有一个或多个过滤装置17。图7是从径向内侧R1观察时的过滤装置17的主视图。以下，以如图7所示从径向内侧R1观察时的过滤装置17的姿势为基准，对过滤装置17进行说明。因此，将图7中的左右方向称为过滤装置17的左右方向X，将图7中的左侧称为左侧X1，将图7中的右侧称为右侧X2。左右方向X与上述的周向S相同或者为相对于周向S的切线方向。过滤装置17具有纵向上长的整体形状。过滤装置17包括：纵向上长的基座30，装配于洗涤桶14的内周部14E；过滤器31，从径向内侧R1与基座30对置配置并向洗涤桶14内露出；以及壳体32，配置于径向R上的基座30与过滤器31之间。
图8是基座30的主视图。基座30中的面向洗涤桶14内的表面部30A在其上端部设有上开口30B，在其下端部设有下开口30C。上开口30B和下开口30C既可以是在径向R上贯通基座30的贯通孔，也可以是向径向外侧R2凹陷的凹部。上开口30B形成为向上侧Z1鼓出的半圆形，下开口30C形成为左右方向X上长的矩形。在基座30设有：左右一对突出部33，向上开口30B内的上区域突出；以及卡合部34，架设于这一对突出部33之间。这一对突出部33在主视时即从径向内侧R1观察时形成为左右对称的大致三角形或扇形。卡合部34为大致矩形的小片状，其下端位于比各突出部33的下端靠上侧Z1处并沿左右方向X延伸。
表面部30A中的上开口30B与下开口30C之间的中间区域30D为左右方向 X上比上开口30B和下开口30C宽的矩形，中间区域30D大体上沿左右方向X和上下方向Z大致平坦。表面部30A中的作为上开口30B、下开口30C以及中间区域30D以外的区域的外缘部30E为向径向内侧R1鼓出的弯曲面。
在中间区域30D中的左右方向X的中央设有向径向内侧R1突出并以将中间区域30D的上端和下端相连的方式沿上下方向Z延伸的第一肋35。第一肋35具有：端面35A，沿左右方向X和上下方向Z平坦并在上下方向Z上细长；以及左右一对弯曲面35B，从端面35A向左右方向X的外侧展开，同时向径向外侧R2延伸。需要说明的是，通过使中间区域30D中的基座30的一部分呈V字状向径向内侧R1凹陷，形成如此形状的第一肋35(参照图11)。
在中间区域30D设有隔着第一肋35以横向排列的方式配置的左右一对流入区域30F。在各流入区域30F，以沿上下方向Z排列的方式配置有多个引导件30G。大部分引导件30G为上下方向Z上薄的板状，但一部分引导30G也可以是横向上长的椭圆形。以下，一对流入区域30F当中，将左侧X1的流入区域30F称为第一流入区域30FA，将右侧X2的流入区域30F称为第二流入区域30FB。当然，第一流入区域30FA和第二流入区域30FB也可以相反地配置。无论如何，第一流入区域30FA和第二流入区域30FB配置为以第一肋35为基准呈左右对称。
过滤器31和壳体32共同构成过滤单元36。图9是处于分解状态的过滤单元36的立体图。在图9中，过滤器31为纵向上长的板状，相较于表面部31A主要表现背面部31B。过滤器31的上端部形成为向上侧鼓出的圆弧状。在过滤器31形成有从其上端向下侧凹陷并在板厚方向上贯通过滤器31的凹部31C。在背面部31B的上端部设有上凸部31D。上凸部31D为横向上长的中空体，配置为遍及过滤器31的短尺寸方向上的背面部31B的整个区域。在上凸部31D的上表面的中央设有卡合部37。卡合部37在向上侧Z1延伸并弯曲后，在图9中大致水平地延伸而局部配置于凹部31C内。这样的卡合部37至少能在上下方向上进行弹性变形。在卡合部37的上表面设有沿过滤器31的短尺寸方向延伸的爪37A。
在背面部31B设有构成其外缘的外周肋31E。外周肋31E的一部分也向凹部31C内露出并与上凸部31D的上表面连接。外周肋31E的下端部构成下凸部 31F。下凸部31F具有：下板31FA，沿着背面部31B的下缘沿过滤器31的短尺寸方向延伸；以及一对侧板31FB，从短尺寸方向上的下板31FA的两端立起。
在背面部31B中的上凸部31D与下凸部31F之间的中间区域31G设有沿过滤器31的长尺寸方向即上下方向延伸的第二肋38。第二肋38配置于过滤器31的短尺寸方向上的中间区域31G的中央，架设于上凸部31D与下凸部31F的下板31FA之间。
在中间区域31G设有隔着第二肋38以横向排列的方式配置的一对即两列捕获区域31H。以下，将图9中的右侧的捕获区域31H称为第一捕获区域31HA，将图9中的左侧的捕获区域31H称为第二捕获区域31HB。当然，第一捕获区域31HA和第二捕获区域31HB也可以相反地配置。无论如何，第一捕获区域31HA和第二捕获区域31HB配置为以第二肋38为基准呈左右对称。在各捕获区域31H设有沿上下方向等间隔排列的多个贯通孔31I。各贯通孔31I的一个例子为四角被倒圆的横向上长的矩形。在各贯通孔31I以堵住贯通孔31I的方式装配有网片39。在网片39形成有无数个作为微小的贯通孔的过滤孔39A。设于第一捕获区域31HA的贯通孔31I的网片39为第一捕获区域31HA的一部分，设于第二捕获区域31HB的贯通孔31I的网片39为第二捕获区域31HB的一部分。因此，在各捕获区域31H分布有多个过滤孔39A。需要说明的是，上述的图7中省略了网片39的图示。此外，也可以使用一体形成于各捕获区域31HA的栅格来代替网片39，在该情况下，栅格的间隙作为过滤孔39A发挥作用。
壳体32为长方形的板状。在壳体32的中央设有沿壳体32的长尺寸方向延伸并贯通壳体32的中继口32A。在图9中的姿势下的壳体32的上表面部设有：外周肋32B，以遍及该上表面部的外缘的整个区域的方式立起；内周肋32C，对中继口32A的整个区域进行包边并且立起；以及呈槽状的一对收容室32D，隔着中继口32A沿着壳体32的长尺寸方向延伸。在壳体32的长尺寸方向上的一端部(图9中右边跟前侧的端部)，外周肋32B的一部分和内周肋32C的一部分被一体化。
将图9中的右边进深侧的收容室32D称为第一收容室32DA，将图9中的左边跟前侧的收容室32D称为第二收容室32DB。当然，第一收容室32DA和第二收容室32DB也可以相反地配置。各收容室32D被外周肋32B和内周肋32C包 围。在图9中的姿势下的壳体32的上表面部设有槽状的第三收容室32E，该第三收容室32E将第一收容室32DA和第二收容室32DB的端部(图9中左边跟前侧的端部)彼此相连。
在壳体32的中继口32A内设有沿壳体32的长尺寸方向延伸的第三肋40。由此，中继口32A被二分为第一收容室32DA侧的第一中继口32AA和第二收容室32DB侧的第二中继口32AB。第一中继口32AA和第二中继口32AB以横向排列的方式配置，第三肋40配置于第一中继口32AA与第二中继口32AB之间。第一中继口32AA和第二中继口32AB配置为以第三肋40为基准呈左右对称。在中继口32A内设有沿壳体32的短尺寸方向延伸的多个横肋41。这些横肋41沿壳体32的长尺寸方向等间隔排列，架设于最靠近的内周肋32C与第三肋40之间。
壳体32中的第三收容室32E侧的端部配置于过滤器31的下凸部31F中的一对侧板31FB之间。壳体32的该端部经由沿壳体32的短尺寸方向延伸的转动轴42与各侧板31FB连结。壳体32能相对于过滤器31绕转动轴42进行相对转动。图9中的壳体32位于分解位置，此时，壳体32的第三肋40处于远离过滤器31的第二肋38的状态。需要说明的是，位于分解位置的壳体32处于载置于下凸部31F的下板31FA的状态，因此该壳体32不会进一步向下侧转动而进一步远离过滤器31。
当使用者使位于分解位置的壳体32绕转动轴42转动而接近过滤器31时，如图10所示，壳体32配置于组装位置而过滤单元36完成。如此，壳体32能在分解位置与组装位置之间转动。位于组装位置的壳体32的长尺寸方向与过滤器31的长尺寸方向一致，壳体32配置于过滤器31的上凸部31D与下凸部31F的下板31FA之间。此外，壳体32的外周肋32B配置于过滤器31的外周肋31E的内侧。使用者能通过使壳体32转动至分解位置来分解过滤单元36(参照图9)。需要说明的是，在过滤单元36的组装、分解时，使用者既可以使过滤器31转动而不使壳体32转动，也可以使过滤器31和壳体32双方转动。
使用者将完成的过滤单元36组装于基座30，将过滤器31的上凸部31D和下凸部31F分别嵌入于基座30的上开口30B和下开口30C(参照图8)。于是，如图7所示，过滤单元36装接于基座30，由此过滤装置17完成。此时，过滤 器31和壳体32各自的长尺寸方向与上下方向Z一致，过滤器31和壳体32各自的短尺寸方向与左右方向X即周向S一致。过滤器31的卡合部37的爪37A(参照图9)从径向外侧R2卡合于基座30的卡合部34(参照图8)，由此防止过滤单元36从基座30脱落。需要说明的是，使用者在使卡合部37向下侧Z2弹性变形而将爪37A从卡合部34拆下时，能使过滤单元36从基座30脱离。
如作为图7的B-B向视剖视图的图11所示，在完成的过滤装置17中，基座30的第一流入区域30FA、过滤器31的第一捕获区域31HA以及壳体32的第一收容室32DA和第一中继口32AA在左右方向X上配置于相同的位置。第一收容室32DA和第一中继口32AA从径向外侧R2与第一捕获区域31HA对置。第一收容室32DA处于从第一捕获区域31HA向径向外侧R2即基座30侧凹陷的状态。此外，基座30的第二流入区域30FB、过滤器31的第二捕获区域31HB以及壳体32的第二收容室32DB和第二中继口32AB在左右方向X上配置于相同的位置。第二收容室32DB和第二中继口32AB从径向外侧R2与第二捕获区域31HB对置。第二收容室32DB处于从第二捕获区域31HB向径向外侧R2凹陷的状态。
此外，基座30的第一肋35、过滤器31的第二肋38以及壳体32的第三肋40在左右方向X上配置于相同的位置。第一肋35的端面35A从径向外侧R2接触第三肋40。第二肋38向第一肋35侧即径向外侧R2突出，从径向内侧R1接触第三肋40。由此，第三肋40被第一肋35和第二肋38从径向R的两侧包夹。第一肋35、第二肋38以及第三肋40被一体化，构成沿上下方向Z和径向R延伸的一个分隔壁43。由此，过滤装置17的内部空间被二分为隔着分隔壁43以横向排列的方式配置的第一内部空间17A和第二内部空间17B。本实施方式中第一内部空间17A配置于第二内部空间17B的左侧X1，但也可以相反地配置。
第一内部空间17A由基座30的第一流入区域30FA、过滤器31的第一捕获区域31HA以及壳体32的第一收容室32DA和第一中继口32AA构成。第一中继口32AA对第一流入区域30FA与第一捕获区域31HA之间进行中继。第二内部空间17B由基座30的第二流入区域30FB、过滤器31的第二捕获区域31HB以及壳体32的第二收容室32DB和第二中继口32AB构成。第二中继口32AB对第二流入区域30FB与第二捕获区域31HB之间进行中继。
在过滤装置17装配于洗涤桶14的内周部14E的洗衣机11的洗涤运转、漂洗运转中，波轮16旋转，由此在洗涤桶14内产生水流。当波轮16在俯视下顺时针正转时，洗涤桶14内的水沿周向S中的第一周向S1流动，流入第一流入区域30FA与壳体32之间的空间。既可以将该空间视为第一流入区域30FA的一部分，也可以将该空间的左端称为过滤装置17的第一流入口17C。当波轮16在俯视下逆时针反转时，洗涤桶14内的水沿周向S中的第二周向S2流动，流入第二流入区域30FB与壳体32之间的空间。既可以将该空间视为第二流入区域30FB的一部分，也可以将该空间的右端称为过滤装置17的第二流入口17D。第一周向S1与右侧X2一致，第二周向S2与左侧X1一致。需要说明的是，也可以通过洗涤桶14旋转而非波轮16旋转来产生水流。在各流入区域30F中，引导件30G配置为偏向左右方向X上的外侧，因此在引导件30G与分隔壁43之间确保了用于取入水的较广阔的空间T。
如箭头P1所示，流入至第一流入区域30FA的水在第一内部空间17A中被引导至分隔壁43的左侧面，经过第一中继口32AA而到达第一捕获区域31HA，并从第一捕获区域31HA中的网片39的过滤孔39A向径向内侧R1流出而回到洗涤桶14内。流出的水中所含的线屑、尘埃等异物F在第一捕获区域31HA被捕获。如箭头P2所示，流入至第二流入区域30FB的水在第二内部空间17B中被引导至分隔壁43的右侧面，经过第二中继口32AB而到达第二捕获区域31HB，并从第二捕获区域31HB中的网片39的过滤孔39A向径向内侧R1流出而回到洗涤桶14内。流出的水中所含的异物F在第二捕获区域31HB被捕获。在图11中，由各捕获区域31H捕获到的异物F通过粗虚线来表示。
如上所述，过滤装置17以基座30、过滤器31以及壳体32这三个较少的部件个数构成。在过滤装置17中，基座30与过滤器31之间的壳体32的第三肋40被基座30的第一肋35和过滤器31的第二肋38包夹，由此这些肋被一体化而构成分隔壁43来加强整个过滤装置17，因此能谋求提高强度。
并且，通过分隔壁43将过滤装置17的内部空间二分为第一内部空间17A和第二内部空间17B并去除可动部件，根据洗涤桶14内的水流的方向，在第一内部空间17A和第二内部空间17B中的某一方毫无遗漏地捕获异物F，由此过滤装置17能以稳定的状态捕获异物F，因此能谋求提高异物F的捕获效率。
在洗衣机11的脱水运转中，当洗涤桶14旋转时，分别留在第一捕获区域31HA和第二捕获区域31HB的异物F通过离心力起作用而欲向径向外侧R2移动。如箭头Q1所示，来自第一捕获区域31HA的异物F被壳体32中的第一收容室32DA容受，如箭头Q2所示，来自第二捕获区域31HB的异物F被壳体32中的第二收容室32DB容受。由此，能防止过滤装置17好不容易捕获到的异物F泄漏至过滤装置17外，因此能谋求进一步提高异物F的捕获效率。需要说明的是，即使第一收容室32DA、第二收容室32DB已满，位于它们的下侧Z2的第三收容室32E也能收容异物F。
并且，能使由过滤器31和壳体32构成的过滤单元36拆装于基座30，因此使用者只需将过滤单元36从基座30拆下并分解就能去除由过滤装置17捕获到的异物F以进行维护(参照图9)。然后，使用者通过完成过滤单元36并将其装配于基座30就能使过滤装置17恢复至可使用状态。
本发明不限于以上说明的实施方式，可在技术方案所记载的范围内进行各种变更。
