本发明涉及一种洗衣机。
以往,在全自动洗衣机中,作为用于收集洗涤时从洗涤物中出来的线屑、尘埃的一种构造,可以采用图10所示的线头收集构造。采用了该过滤收集构造的洗衣机在例如专利文献1中有记载。
图10(a)是表示线头过滤收集构造的洗涤脱水桶500的主要部位剖视图。在洗涤脱水桶500的侧面部,通过水路形成构件510形成有环流水路520。在水路形成构件510,形成有向后方凹陷的过滤器安装部511,在过滤器安装部511自由装卸地设置有过滤器单元530。在过滤器安装部511,在下表面511a形成有向上方突出的第一支轴512,在上表面511b形成有第一轴孔513,在后表面511c形成有流出口514。设置于过滤器单元530的下部的第二轴孔531嵌入第一支轴512,设置于过滤器单元530的上部的第二支轴532嵌入第一轴孔513。由此,过滤器单元530以第一支轴512和第二支轴532为旋转轴,只能向左右方向旋转规定的角度。环流水路520连接到波轮540的侧面。
当波轮540旋转时,如箭头F1所示,由波轮540的抽水叶片541向外周方向推出的水被导入环流水路520内,从流出口514流出,流经过滤器单元530返回洗涤脱水桶500内。此时,水中含有的线屑等被过滤器单元530收集。
此外,过滤器单元530被由波轮540的旋转而产生的水流推动进行旋转,如箭头F2所示,沿着洗涤脱水桶500的内周壁流动的水从后表面的吸入口533流入过滤器单元530内,并穿过过滤器单元530内。此时,与水一起流入的线屑等被线头过滤器单元530收集。

发明所要解决的问题
水路形成构件510可以由树脂材料形成。在这种情况下,水路形成构件510
用模具通过成型而制得。
图10(b)是示出将水路构成构件510成型的模具M的主要部位的图。例如,对于水路形成构件510的成型,可以使用由正面侧的第一模具M1和背面侧的第二模具M2构成并沿着水路形成构件510的前后方向分割的模具M。在这种情况下,由于第一支轴512的一侧由第二模具M2形成,因此在过滤器安装部511的后表面511c,在第一支轴512的背后的位置形成有供第二模具M2通过的开口部515。需要说明的是,也可以对模具M追加向第一支轴512的突出方向滑动的第三模具,通过该第三模具形成第一支轴512。但是,在这种情况下,未形成开口部515,有可能会在后表面511c形成滑动痕迹,有损外观品相或挂住线屑等。
形成于水路形成构件510的开口部515与环流水路520内连通。因此,如图10(a)的箭头F3所示,朝向流出口514流过环流水路520的水的一部分从开口部515流出。流出的水不经过过滤器单元530就返回洗涤脱水桶500内。这样的话,可能会降低过滤器单元530的线屑等的收集效率。
发明内容
因此,本发明的目的在于,提供一种能提高线屑等的收集效率的洗衣机。
用于解决问题的方案
本发明的实施方式的洗衣机具备:洗涤脱水桶,收容洗涤物;波轮,自由旋转地配置于所述洗涤脱水桶的底部;环流水路,设置于所述洗涤脱水桶的侧面部,供通过所述波轮的旋转而送来的水流过;树脂制的水路形成构件,与所述洗涤脱水桶的内周壁之间形成所述环流水路;过滤器安装部,形成于所述水路形成构件;以及过滤器单元,可旋转地安装于所述过滤器安装部,吸入从所述环流水路返回所述洗涤脱水桶内的水和通过由所述波轮的旋转而产生的水流而沿着所述内周壁流动的水并使其通过,收集通过的水中含有的线屑等集。这里,所述过滤器安装部包括构成所述过滤器单元的旋转轴的支轴和形成于该支轴的背后并与所述环流水路内连通的开口部。进而,在所述水路形成构件的面向所述环流水路的面,朝向所述内周壁侧地形成有抑制来自所述开口部的水的流出的壁部。
通过上述的结构,由于能将流过环流水路内的水良好地导入过滤器单元内,
因而可望提高过滤器单元的线屑等的收集效率。
在本实施方式的洗衣机中,所述壁部可以采用至少包围所述开口部的下方和左右方这三方的结构。
通过上述的结构,能抑制与壁部的下侧的壁相撞而短暂分流的水从侧面流入开口部,能进一步抑制来自开口部的水的流出。
在采用上述的结构的情况下,进而,可以在所述壁部与所述内周壁之间形成间隙。
当采用这样的结构时,在进行脱水过程时,即使从洗涤物排出的水进入包围了开口部的至少三方的壁部的内部,也能使进入的水从间隙流出到环流水路内。因此,能防止水一直残留在壁部的内部。
对于本实施方式的洗衣机,可以采用所述壁部包括突出部的结构,该突出部具有中央部比所述开口部的左右方向的两端部更向所述环流水路的上游侧突出的形状。
通过上述的结构,流过环流水路内的水通过与突出部相撞而顺利地向左右分流。由此,由于能抑制环流水路内的水的流速的降低,因而能使线屑等借着水流良好地运送到过滤器单元。
发明效果
通过本发明,能提供一种能提高线屑等的收集效率的洗衣机。

以下,关于本发明的洗衣机的一实施方式的全自动洗衣机,参照附图进行说明。
图1是示出全自动洗衣机1的结构的侧面剖视图。
全自动洗衣机1具备构成外观的机壳10。机壳10包括:上下面打开的方形筒状的机身部11、覆盖机身部11的上表面的上面板12、以及支承机身部11的脚台13。上面板12形成有洗涤物的投入口14。投入口14由自由开闭的上盖15覆盖。
在机壳10内,外桶20由未图示的4根吊棒弹性地悬挂支承。在外桶20内,配置有洗涤脱水桶21。外桶20和洗涤脱水桶21稍微向前方倾斜。洗涤脱水桶21以相对于铅直方向稍微向前方倾斜的旋转轴R为中心进行旋转。机壳10具有与外桶20的上部向前方突出的程度相对应地向前方突出的突出部10a。
在洗涤脱水桶21的内周壁21a,形成有许多脱水孔21b。此外,在洗涤脱水桶21的底面,形成有多个通水孔21c。进而,在洗涤脱水桶21的上部,设置有平衡环22。
在洗涤脱水桶21的底部,配置有波轮23。在波轮23的表面,形成有从表面中央放射状地延伸的多个叶片23a。此外,在波轮23的背面,形成有从背面中央放射状地延伸的多个抽水叶片23b。这些抽水叶片23b配置在形成于波轮23的背面与洗涤脱水桶21的底面之间的泵室24中。
沿着洗涤脱水桶21的内周壁21a向上下方向延伸的环流水路25由水路形成构件26和内周壁21a形成。环流水路25的下端部与泵室24相连。过滤器单元27可拆卸地安装在环流水路25即构成环流水路25的水路形成构件26。过滤器单元27收集洗涤时从洗涤物中出来的线屑、尘埃。
在外桶20的外底部,配置有驱动洗涤脱水桶21和波轮23的产生转矩的驱动单元30。驱动单元30包括驱动电机31和传递机构部32。传递机构部32具有离合器机构,通过该离合器机构的切换操作,在洗涤过程和漂洗过程中,将驱动电机31的转矩只传递给波轮23从而只让波轮23旋转;在脱水过程中,将驱动电机31的转矩传递给波轮23和洗涤脱水桶21,使波轮23和洗涤脱水桶21一体地旋转。此外,传递机构部32具有减速机构。在洗涤过程和漂洗过程中,波轮23以驱动电机31的转速按照减速机构的减速比被降低后的转速进行旋转。
在外桶20的外底部,形成有排水口部20a。在排水口部20a,设置有排水阀40。排水阀40与排水软管41连接。当排水阀40打开时,蓄于洗涤脱水桶21和外桶20的水通过排水软管41被排出到机外。
在上面板12的后部,配置有用于将自来水提供到洗涤脱水桶21内的给水单元50。给水单元50连接有给水阀51,给水阀51与水龙头连接。给水单元50在进行洗涤运转时被投入洗涤剂。当给水阀51打开时,给水单元50内被导入自来水。导入的自来水在给水单元50内与洗涤剂混合之后从给水单元50流出,被提供到洗涤脱水桶21内。
全自动洗衣机1进行各种运转模式的洗涤运转。洗涤运转包括洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。
在洗涤过程和漂洗过程中,在洗涤脱水桶21内蓄有水的状态下,波轮23向右方向和左方向旋转。通过波轮23的旋转在洗涤脱水桶21内产生水流。在洗涤过程中,通过产生的水流和水中含有的洗涤剂清洗洗涤物。在漂洗过程中,通过产生的水流漂洗洗涤物。
在中间脱水过程和最终脱水过程中,洗涤脱水桶21和波轮23一体高速旋转。洗涤物通过洗涤脱水桶21产生的离心力的作用而被脱水。
本实施方式的全自动洗衣机1以由环流水路25和过滤器单元27构成的线头收集构造为特征,以下,关于线头收集构造进行详细说明。
图2是示出了环流水路25的周边部分的洗涤脱水桶21的主要部位纵剖图。图3是示出了环流水路25的周边部分的洗涤脱水桶21的主要部位横剖图,图3(a)示出产生了右旋的水流时的状态,图3(b)示出产生了左旋的水流时的状态。图4是示出过滤器单元27的结构的图,图4(a)是过滤器单元27的立体图,图4(b)是过滤器单元27的侧面纵剖图。图5和图6分别是示出水路形成
构件26的结构的主视图和后视立体图。
过滤器单元27具备线头过滤器110和过滤器盒120。线头过滤器110由网格织物的袋体构成。过滤器盒120形成为中空的纵长的立方体形状,其后表面作为吸入口121开口。在过滤器盒120的前表面形成有安装开口部122,在该安装开口部122安装有线头过滤器110。
在过滤器盒120的上端部,形成有可以向下方弯曲的弹性片123,在该弹性片123的上表面,形成有向上方突出的上部支轴124。此外,在弹性片123的前端部形成有操作片125。用户能通过用手指按压该操作片125从而使弹性片123向下方弯曲。进而,在过滤器盒120的下端部,形成有下部轴孔126。
水路形成构件26由树脂材料形成,向上下方向延伸并且稍微向前方鼓起。对于水路形成构件26,其表面朝向洗涤脱水桶21的内部,其背面朝向环流水路25的内部。在水路形成构件26的表面,形成有凹成与过滤器单元27的过滤器盒120对应形状的过滤器安装部201。
在过滤器安装部201,在其底部201a形成有向上方突出的下部支轴202,在其上部201b形成有上部轴孔203。下部支轴202相当于本发明的支轴。
在过滤器安装部201的后表面201c,在中央部和中央部稍微靠下方处,形成有多个流出口204。此外,在过滤器安装部201的后表面201c,在上部形成有凹部205。当过滤器单元27已安装于过滤器安装部201时,过滤器单元27的弹性片123的后部收容于凹部205。
进而,在过滤器安装部201的后表面201c,在下部支轴202的背后的位置,形成有比下部支轴202稍大的方形的开口部206。水路形成构件26用模具通过成型而制得。如由图10(b)说明的那样,为了在成型制造时供形成下部支轴202的模具通过而形成有开口部206。开口部206与环流水路25内连通。
在水路形成构件26的表面,在过滤器安装部201的左右两侧,分别形成有多个与过滤器安装部201同样凹陷并且向左右方向延伸的右流路207和左流路208。
在水路形成构件26的背面,朝向后方地形成有双重构造的水路划分筋209。水路划分筋209的内侧区域构成环流水路25。进而,在水路形成构件26的背面,在开口部206的周围,朝向后方即朝向洗涤脱水桶21的内周壁21a侧地形成有阻水壁部210。阻水壁部210相当于本发明的壁部。阻水壁部210以包围开口部
206四方的方式形成为方形的筒状,具有下壁211、上壁212、左壁213以及右壁214。如图2所示,在水路形成构件26已安装于洗涤脱水桶21的内周壁21a的状态下,在阻水壁部210与内周壁21a之间形成有规定的间隙S。
过滤器单元27安装于水路形成构件26的过滤器安装部201。安装水路形成构件26时,用户首先将过滤器安装部201的下部支轴202嵌入过滤器单元27的下部轴孔126。接着,用户按下过滤器单元27的操作片125,一边以使上部支轴124比过滤器安装部201的上部轴孔203低的方式使弹性片123向下方弯曲,一边使过滤器单元27的上部向后方移动。然后,当上部支轴124到达上部轴孔203的位置时,用户放开对弹性片123的弯曲,将上部支轴124嵌入上部轴孔203。过滤器单元27以如下状态固定在水路形成构件26:以上部支轴124和下部支轴202为旋转轴,从水路形成构件26的正面观察只能向右方向或左方向旋转规定角度。
接着,参照图2和图3,关于过滤器单元27的线屑等的收集动作进行说明。
在洗涤过程或漂洗过程中,当波轮23旋转时,通过抽水叶片23b的抽吸作用,洗涤脱水桶21与外桶20之间的水经过通水孔21c被吸入泵室24内,向外周方向被推出。如箭头F1所示,被推出来的水在环流水路25内上升并从流出口204流出,经过过滤器单元27的线头过滤器110返回洗涤脱水桶21内。此时,水中含有的线屑等被线头过滤器110收集。
此外,如图3(a)和(b)所示,当因波轮23的旋转而产生右旋或左旋的水流时,过滤器单元27向右方向或左方向倾斜。由此,如箭头F2所示,沿着洗涤脱水桶21的内周壁21a流动的水从后表面的吸入口121流入过滤器单元27内,流过线头过滤器110。此时,水中含有的线屑等被线头过滤器110收集。
图7是示出朝向流出口204流到环流水路25内的水流图。位于流出口204的上游的开口部206由阻水壁部210包围,在环流水路25内上升的水与阻水壁部210的下壁211相撞从而向左右分流,流过阻水壁部210的左右两侧到达流出口204。由此,能抑制流过环流水路25内的水的一部分从开口部206流出的情况。
需要说明的是,在进行脱水过程时,有可能发生从洗涤物排出的水经过开口部206进入阻水壁部210的内部的情况。在这种情况下,进入的水从阻水壁部210与内周壁21a的间隙S流到环流水路25内。因此,不容易在阻水壁部210
的内部一直残留水。
<本实施方式的效果>
以上,通过本实施方式,能通过设置于水路形成构件26的背面的阻水壁部210抑制流过环流水路25内的水的一部分从开口部206流出的情况。因此,由于能将流过环流水路25内的水良好地导入过滤器单元27内,因而可望提高过滤器单元27的线屑等的收集效率。
此外,通过本实施方式,由于阻水壁部210采用围住开口部206四方的结构,因而能抑制在下壁211短暂分流的水从侧面流入开口部206,能进一步抑制来自开口部206的水流出。
进而,通过本实施方式,由于在阻水壁部210与洗涤脱水桶21的内周壁21a之间形成有间隙S,因而在脱水过程时进入阻水壁部210的内部的水能从间隙S流出到环流水路25内,能防止在阻水壁部210的内部一直残留水。
以上,关于本发明的实施方式进行了说明,但本发明不受上述实施方式的任何限制,另外,本发明的实施方式也可以进行上述以外的各种变更。
<变更例1>
图8(a)是示出变更例1所涉及的阻水壁部210A的结构的水路形成构件26的主要部位后视立体图。
本变更例的阻水壁部210A只由在开口部206的下缘向左右方向延伸的下壁211构成。阻水壁部210A的宽度设定为比开口部206的横向宽度更大。在环流水路25内上升的水与阻水壁部210A相撞而向左右分流,流过开口部206的左右两外侧到达流出口204。
因此,通过本变更例,也能抑制流过环流水路25内的水的一部分从开口部206流出的情况,可望提高过滤器单元27的线屑等的收集效率。
<变更例2>
图8(b)是示出变更例1所涉及的阻水壁部210B的结构的水路形成构件26的主要部位后视立体图。
本变更例的阻水壁部210B在下壁211的下方包括突出部215,该突出部具有中央部比左右的两端部更向环流水路25的上游侧突出的大致V字形状。在环流水路25内上升的水与突出部215相撞而向左右分流,流过阻水壁部210B的左右两侧到达流出口204。
因此,通过本变更例,也能抑制流过环流水路25内的水的一部分从开口部206流出的情况,可望提高过滤器单元27的线屑等的收集效率。
进而,通过本变更例,流过环流水路25内的水通过与突出部215相撞而顺利地向左右分流。由此,由于能抑制环流水路25内的水的流速的降低,因此能使线屑等乘着水流良好地运送到过滤器单元27。
<其它的变更例>
除了上述实施方式的阻水壁部210、上述变更例1的阻水壁部210A以及上述变更例2的阻水壁部210B之外,作为抑制来自开口部206的水的流出的壁部,也可以与开口部206关联设置例如如图9所示的各种阻水壁部210C~210I。
例如,如图9(a)所示,也可以设置没有上壁212,由下壁211、左壁213以及右壁214包围开口部206的阻水壁部210C。此外,如图9(b)所示,也可以设置虽然具有下壁211、左壁213以及右壁214,但是左右壁213、214没有延伸到开口部206的上端的阻水壁部210D。由于只要以如图9(a)和(b)的阻水壁部210C、210D所示的方式包围开口部206的至少下方和左右方这三方,就能抑制在下壁211暂时分流的水从侧面流入开口部206的情况,因此与变更例1那样只由下壁211构成的阻水壁部210A相比,能进一步抑制来自开口部206的水的流出。
进而,如图9(c)所示,也可以设置没有下壁211,形成有从左右壁213、214突出的V状的突出部215的阻水壁部210E。进而,如图9(d)和(e)所示,也可以设置具有非V字状的圆弧或U字状的突出部216的阻水壁部210F、210G。进而,如图9(f)所示,也可以设置只由V字状的突出部215构成的阻水壁部210H。进而,如图9(g)所示,也可以设置只由圆弧或U字状的突出部216构成的阻水壁部210I。
进而,在上述实施方式中,水路形成构件26向上方延伸到平衡环22的位置,比过滤器单元27更靠上方的部位作为供通过水流而被搅拌的洗涤物摩擦的挡板发挥功能。但是,由于上方的部位未发挥环流水路25的功能,因此也可以撤除。
进而,在上述实施方式中,虽然外桶20和洗涤脱水桶21向前方倾斜,但它们也可以不倾斜。
虽然上述实施方式的全自动洗衣机1不具备干衣功能,但是本发明也能用
于具备干衣功能的全自动洗衣机。
此外,本发明的实施方式可以在权利要求书示出的技术思想的范围内适当地进行各种变更。
