发明内容
发明要解决的问题
专利文献1的洗衣机有可能会产生因转动的洗涤叶片摩擦洗涤物而导致洗涤物损伤的问题。此外，将汲上来的洗涤水只泼到洗涤物上的结构在提高洗涤物的清洗力的方面存在局限。
专利文献2的洗衣机通过将洗涤物放置于洗涤物放置用网而与波轮隔离开来。由此，能消除因旋转的波轮摩擦洗涤物而导致洗涤物损伤的问题。但是，由于在洗涤兼脱水槽中能够容纳洗涤物的区域只有洗涤物放置用网以上的区域，因而洗涤兼脱水槽的容量变小。这样的话，由于有可能无法在洗涤兼脱水槽内充分搅拌洗涤物，因而在提高洗涤物的清洗力的方面存在局限。
本发明是基于该背景而完成的，其目的在于，提供一种洗衣机，其能在防止洗涤物损伤的同时实现清洗力的提高。
用于解决问题的方案
本发明为一种洗衣机，其特征在于，包括：收容洗涤物并存积水的洗涤槽；具有位于所述洗涤槽的底部的入口、位于比所述入口更高位置的纵长的狭缝状的出口、以及从所述入口向上方延伸到所述出口的流路，从所述入口抽取存积在所述洗涤槽内的水并通过所述流路汲上来从所述出口喷到所述洗涤槽内的抽水路；设置于所述抽水路，堵住所述流路的上端的闭塞构件；以及以与洗涤物隔离的方式设置在所述洗涤槽的底部，通过进行旋转，将存积于所述洗涤槽的水送入所述入口的叶轮。
此外，本发明的特征在于，包括分隔构件，该分隔构件设置于所述洗涤槽的底部，将所述洗涤槽的内部空间分隔为配置洗涤物的第一空间和配置所述叶轮的第二空间。
此外，本发明的特征在于，所述闭塞构件位于所述出口的上端。
此外，本发明的特征在于，所述洗涤槽为具有纵向延伸的轴线的圆筒状洗涤槽，在所述抽水路，所述出口相对于所述洗涤槽的圆周方向上的所述入口的中心，向所述圆周方向偏移。
此外，本发明的特征在于，所述出口以朝向所述圆周方向的方式配置。
此外，本发明的特征在于，所述出口在所述抽水路中设置在所述圆周方向上的两侧。
此外，本发明的特征在于，所述出口在所述抽水路中设置在所述圆周方向上的单侧，并且本发明包括倾斜构件，该倾斜构件以往所述出口靠近的方式倾斜，使得所述流路从所述入口开始越是靠近所述出口越窄。
发明效果
根据本发明，将存积于洗涤槽的水送入抽水路的入口的叶轮以与洗涤物隔离的方式设置在洗涤槽的底部。因此，由于即使叶轮为了将水送入从而进行旋转，洗涤物也不会不被叶轮摩擦，因而能防止洗涤物的损伤。
在抽水路，从入口向上方延伸到出口的流路的上端由闭塞构件堵住，出口为纵长的狭缝状。因此，从入口抽取并通过流路汲上来的水在由闭塞构件改变了流向之后，通过纵向细长的出口而加快流速之后被喷出。由此，由于从出口喷出的水朝着纷乱的方向，喷射成纵向扩散的带状，强劲地泼到洗涤槽内的洗涤物上，因而洗涤物一边被向各个方向搅拌一边进行清洗。因此，能实现清洗力的提高。
此外，根据本发明，由于分隔构件将洗涤槽的内部空间分隔为配置洗涤物的第一空间和配置叶轮的第二空间，因而能将叶轮与洗涤物可靠地隔离开来。
此外，根据本发明，由于闭塞构件位于出口的上端，因而能将通过流路汲上来的水的流向在即将到出口之前改变。由此，能可靠地使从出口喷出的水喷射向纷乱的方向。
此外，根据本发明，在抽水路，出口以相对于洗涤槽的圆周方向上的入口的中心，向圆周方向偏移的方式配置。由此，能使从入口抽取并通过流路汲上来的水流发生变化，使汲上来的水从出口强劲地喷射到洗涤槽内。因此，能将被泼了喷射的水的洗涤物通过充分搅拌而有效地进行清洗。
此外，根据本发明，由于出口以朝向圆周方向的方式配置，因而能将通过流路汲上来的水从出口向圆周方向喷出。由此，利用向圆周方向喷出的水，能将洗涤槽内的洗涤物一边以向圆周方向旋转的方式搅拌一边进行清洗。
此外，根据本发明，由于出口在抽水路中设置于圆周方向上的两侧，因而能够对应洗涤槽的旋转方向，在两侧的出口中的一方出口和另一方出口改变从出口喷出的水的朝向。由此，在抽水路，由于能将从各出口喷出的水朝向纷乱的方向泼向洗涤槽内的洗涤物，因而能将洗涤物通过向各个方向充分地搅拌而有效地进行清洗。
此外，根据本发明，由于出口在抽水路中设置于圆周方向上的单侧，因而能防止在圆周方向上并排配置有多个抽水路的情况下，从相邻抽水路的出口喷出的水相互碰撞而失势。
抽水路的流路通过倾斜构件，从入口越往出口越窄。由此，能将从入口抽取并通过流路汲上来的水的流速随着朝向出口而加速。因此，能将汲上来的水从出口更加强劲地喷射到洗涤槽内。因此，能将泼了喷射的水的洗涤物通过充分地搅拌而有效地进行清洗。

具体实施方式
以下，参照附图，就本发明的实施方式进行具体说明。
图1是本发明的一个实施方式的洗衣机1的内部构造的纵剖视图。
首先，以图1的上下方向X为基准就洗衣机1的概要进行说明。在作为纵向的上下方向X中，将上方称为上方X1，将下方称为下方X2。此外，洗衣机1还包括具有洗涤物S的干衣功能的洗衣干衣机。
洗衣机1包括机壳2、外槽3、洗涤槽4、以及电机5。
机壳2形成为箱状。外槽3、洗涤槽4以及电机5配置于机壳2内。
外槽3为例如树脂制，形成为有底圆筒状。外槽3具有：在上端具有开口部3A的大致圆筒状的圆周壁3B、将圆周壁3B的中空部分从下方X2堵塞的圆板形状的底壁3C。开口部3A通过与圆周壁3B连结的盖6进行开闭。在外槽3内，能存积自来水、洗澡水以及溶解有洗涤剂的液体等种类的水。
洗涤槽4形成为比外槽3小一圈的有底圆筒状，收容洗涤物S。洗涤槽4具有：在上端具有出入口4A的大致圆筒状的圆周壁4B、将圆周壁4B的中空部分从下方X2堵塞的圆板形状的底壁4C。例如，圆周壁4B为金属制，在底壁4C，圆心部分为金属制，外周部分为树脂制。底壁4C和圆周壁4B中与底壁4C连接的下端部构成洗涤槽4的底部4D。洗涤槽4以同轴状态收容在外槽3内。处在收容于外槽3内的状态下的洗涤槽4能够以作为其轴线向上下方向X延伸的中心轴7为中心进行旋转。这样的洗涤机1是纵向配置洗涤槽4的纵型洗衣机。
出入口4A从下方X2与开口部3A连通，开口部3A和出入口4A通过盖6一并进行开闭。洗衣机1的使用者能够经由打开的出入口4A，将洗涤物S置入 取出洗涤槽4内。在圆周壁4B和底壁4C上各自形成有贯通孔4E，外槽3内的水能经由贯通孔4E在外槽3和洗涤槽4之间来回。由此，洗涤槽4存储有与外槽3相同水位的水。
在圆周壁4B的内周面4F的上端部，安装有环状的减振器8。减振器8是使旋转时的洗涤槽4的振动减少的构件，在减振器8的内部的空洞8A，收容有用于有助于减少振动的液体。
在底壁4C的上表面，形成有向下方凹陷的凹部4G。凹部4G为与底壁4C呈同轴状态的上下扁平的圆筒状的空间。洗涤槽4包括设置于底部4D的分隔构件9。分隔构件9为将凹部4G从上方堵塞的圆板状的盖，并且在其圆心侧，集中形成有多个贯通孔9A。分隔构件9将洗涤槽4的内部空间10分隔为与出入口4A连通并配置洗涤物S的第一空间11和相当于凹部4G的第二空间12。
电机5在机壳2内配置于外槽3的底壁3C的下方X2。电机5的输出轴分支为向上方X1延伸的管状的第一输出轴5A和宽裕有余地插入第一输出轴5A的第二输出轴5B。电机5通过变速机构15，从第一输出轴5A和第二输出轴5B之中择一输出驱动力。
第一输出轴5A向上方X1延伸，依次贯通底壁3C的圆心和洗涤槽4的底壁4C的圆心。第一输出轴5A具有呈帽檐状突出到底壁3C和底壁4C之间的凸缘部5C，并通过凸缘部5C固定于底壁4C，由此与洗涤槽4连结。当电机5被驱动并向第一输出轴5A传递驱动力时，洗涤槽4进行旋转。
在第二输出轴5B，在比凸缘部5C更向上方X1露出的上端部，安装有叶轮13。
图2为从上方X1观察叶轮13的立体图，图3为从下方X2观察叶轮13的立体图。
参照图2和图3，叶轮13一体地包括呈同轴状态上下平行地配置的一对圆板13A和架设于一对圆板13A之间并且以圆板13A的圆心为基准放射状地延伸的多个叶片13B。一对圆板13A当中，在上方X2的圆板13A，形成有贯通其圆心部分的一个圆形的贯通孔13C(参照图2)，在下方X2的圆板13A，形成有包围其圆心部分的多个圆形的贯通孔13D(参照图3)。各个叶片13B从贯通孔13C的边缘朝向圆板13A的外周缘直线延伸。
参照图1，叶轮13配置于洗涤槽4的底部4D的第二空间12(上述的底壁 4C的凹部4G)。由于第二空间12处于通过分隔构件9与配置洗涤物S的上方X1的第一空间11阻隔的状态，因而叶轮13以与洗涤物S隔离的方式设置在底部4D。存积于洗涤槽4的水经由分隔构件9的贯通孔9A、叶轮13的一对圆板13A的贯通孔13C、13D，还存在于一对圆板13A之间。
电机5的第二输出轴5B的上端部安装于下方X2的圆板13A的圆心部分。当电机5被驱动并且向第二输出轴5B传递驱动力时，叶轮13进行旋转。叶轮13进行旋转时，洗涤槽4处于停止的状态。
图4是图1的A-A向视剖视图。在图4中，为了方便说明，省略了上述的分隔构件9的图示。参照图4，以下，将洗涤槽4的内周面4F的圆周方向称为圆周方向Y，将内周面4F的径向称为径向Z。圆周方向Y和径向Z均是沿着水平方向H的方向。在圆周方向Y当中，将俯视时的顺时针的方向称为顺时针Y1，将俯视时的逆时针的方向称为逆时针Y2。在径向Z当中，将朝向中心轴7的一侧称为径向内侧Z1，将远离中心轴7的一侧称为径向外侧Z2。
在洗涤槽4的内周面4F，安装有抽水路20。抽水路20的数量能任意设定，既可以是单个也可以是多个。在本实施方式中，同形状以及同尺寸的三个抽水路20以排列在圆周方向Y上的状态，安装于内周面4F。需要说明的是，在图4中，为了方便说明，只图示出一个抽水路20。在圆周方向Y上相邻的抽水路20的间隔既可以是所有的抽水路20彼此之间间距固定，也可以根据不同的抽水路20而有所不同。以下，以安装于洗涤槽4的状态下的样子为基准，关于抽水路20的细节进行说明。
抽水路20包括树脂制的主体部21。主体部21为上下方向X上长边的盖状，以架设于减振器8和洗涤槽4的底壁4C之间并且沿着上下的姿势，从径向内侧Z1安装在洗涤槽4的内周面4F(还参照图1)。因此，主体部21具有与洗涤槽4的内周面4F对置的背面21A和位于背面21A相反侧并面对中心轴7侧的表面21B。
图5以及图6为以其它的视点从上方X1观察洗涤槽4的底部4D以及抽水路20的立体图。参照图5以及图6，在主体部21，圆周方向Y上的两端部构成遍及上下方向X上的大致整个区域地向径向外侧Z2弯折的弯曲部21C。各个弯曲部21C以相对于圆周方向Y以及径向Z都倾斜的方式形成，各个弯曲部21C的表面21B处于朝向圆周方向Y的状态。此外，在主体部21，上端部21D向径 向外侧Z2弯折，架设于两侧的弯曲部21C之间。
在各个弯曲部21C，形成有纵长的狭缝状的出口22。换句话说，出口22在抽水路20中设置于圆周方向Y上的两侧。出口22例如在上下方向X上两个并排地设置在各个弯曲部21C，以从主体部21的背面21A以及表面21B两方露出的方式贯通弯曲部21C。各个出口22以在弯曲部21C的表面21B，朝向周方向Y的方式配置(还参照图4)。
在各个弯曲部21C，在上下相邻的出口22之间、位于上方X1的出口22的上方X1、以及位于下方X2的出口22的下方X2，分别一体地设置有往径向内侧Z1延伸的突起23。突起23从主体部21的表面21B向径向内侧Z1突出。如图6所示，在突起23的径向外侧Z2的端面，形成有螺纹孔23A。螺纹孔23A还形成于主体部21的上端部21D。在螺纹孔23A，装配有为了将抽水路20固定于洗涤槽4而从洗涤槽4的径向外侧Z2插入的螺钉(未图示)。
在各个弯曲部21C的背面21A，螺纹孔23A配置于比出口22更靠圆周方向Y上的外侧。在主体部21的背面21A，在圆周方向Y上的两侧，逐一设置有向径向外侧Z2突出并且沿着上下方向X直线延伸的筋21E。筋21E为圆周方向Y上较薄的板状，并且在各个弯曲部21C，在圆周方向Y上的螺纹孔23A和出口22之间，从上端部21D向下方X2延伸。筋21E以将出口22从圆周方向Y上的外侧包边的方式，与出口22邻接配置。
图7为图4的B-B向视剖视图。参照图7，在主体部21的背面21A的下端部，一体地设置有入口构件24。入口构件24形成为俯视时弯折成向径向外侧Z2膨出的大致U字状的板状(参照图4)。圆周方向Y上的入口构件24的宽度往上方X1徐徐变窄。入口构件24的下部24A以比主体部21的下端更往下方突出的方式配置。由大致U字状的下部24A夹住的区域为抽水路20的入口25。入口25在抽水路20中位于比出口22更低的位置。此外，在各个抽水路20，所有的出口22以相对于圆周方向Y上的入口25的中心25A向圆周方向Y偏移的方式配置。
在洗涤槽4的底壁4C，与抽水路20相同数目地形成有从配置有叶轮13的第二空间12向径向外侧Z2凹的凹陷4H(还参照图5)，该凹陷4H能够接纳任一抽水路20的入口构件24。因此，在抽水路20已安装于洗涤槽4的状态下，入口25位于洗涤槽4的底部4D，处于从径向外侧Z2与第二空间12连通的状 态(参照图5)。
在主体部21的背面21A，设置有流路26。流路26为由背面21A的圆周方向Y上的两侧的筋21E从圆周方向Y包夹的上下为长边的空间(还参照图6)，由洗涤槽4的内周面4F从径向外侧Z2堵塞。流路26的下端部由主体部21的背面21A和入口构件24从径向Z包夹。流路26以在下端与入口25连通，在上端与出口22连通的方式从入口25向上方X1延伸至出口22。
在主体部21的背面21A的上部，一体地设置有闭塞构件27(还参照图6)。闭塞构件27形成为在上下方向X上较薄并且向水平方向H延伸的板状，架设于主体部21的两侧的筋21E之间。闭塞构件27位于各个弯曲部21C的最上位的出口22的上端。闭塞构件27的下表面27A在水平方向H上是平坦的，流路26的上端处于由下表面27A从上方X1堵塞的状态。因此，流路26其上端为末端。
参照图1，当叶轮13进行旋转时，存积于洗涤槽4的底部4D的水通过叶轮13的叶片13B被送入到各抽水路20的入口25，从入口25被抽取到流路26内。被抽取到流路26内的水如粗线箭头所示，通过流路26被汲到上方X1的出口22，然后，从各个出口22喷出到洗涤槽4内。
如上所述，在抽水路20中，从入口25向上方X1延伸到出口22的流路26的上端如图7所示，由闭塞构件27堵塞，出口22为纵长的狭缝状。因此，从入口25抽取并通过流路26汲上来的水在通过闭塞构件27改变流向之后，通过纵向上细长的出口22加快流速之后喷出。
在从叶轮13的旋转方向观察，将圆周方向Y上的抽水路20的两侧的出口22当中，下游侧的出口22称为下游侧出口22A，上游侧的出口22称为上游侧出口22B的基础上，以下，关于水从出口22喷出的现象进行具体说明。在图7中，将右侧的出口22作为下游侧出口22A，将左侧的出口22视为上游侧出口22B。
在叶轮13向顺时针方向Y1旋转的情况下，在抽水路20的流路26内汲上来的水一边向顺时针方向Y1流动一边上升。在到达闭塞构件27之前已到达下游侧出口22A的水在借助下游侧出口22A加快了流速的状态下，从下游侧出口22A向顺时针方向Y1且向斜上方强劲地喷出(参照粗实线箭头)。
另一方面，撞到闭塞构件27上的水在因闭塞构件27而向逆时针方向Y2且 向斜下方反弹之后，到达上游侧出口22B。闭塞构件27由于如上所述位于出口22的上端，因而能将通过流路26汲上来的水的流向在即将到上游侧出口22B之前改变。到达上游侧出口22B的水在借助上游侧出口22B加快流速的状态下，从上游侧出口22B向逆时针方向Y2且向斜下方强劲地喷出(参照粗虚线箭头)。
此外，在叶轮13向逆时针方向Y2旋转的情况下，会产生与叶轮13向顺时针方向Y1旋转的情况相反的现象。换句话说，下游侧出口22A以及上游侧出口22B的圆周方向Y上的位置互换，在流路26内汲上来的水从下游侧出口22A向逆时针方向Y2且向斜上方强劲地喷出，从上游侧出口22B向顺时针方向Y1且向斜下方强劲地喷出(未图示)。
如上所述，出口22设置于圆周方向Y上的两侧的抽水路20能够对应洗涤槽4的旋转方向，通过两侧的出口22中的一方出口22和另一方出口22，改变从出口22喷出的水的朝向。因此，由于从各个出口22喷出的水朝向纷乱的方向喷射成往纵向扩散的带状，强劲地泼到洗涤槽4内的洗涤物S上，因而能通过复杂变化的强力水流将洗涤物S一边向各方向搅拌一边进行清洗。因此，能实现清洗力的提高。另外，纵长的出口22与横长的情况相比，能使从出口22喷出的水的流动变复杂。
如上所述，在各个抽水路20，出口22以相对于入口25的中心25A向圆周方向Y偏移的方式配置。由此，使从入口25抽取并通过流路26汲上来的水流发生变化，将汲上来的水从出口22向洗涤槽4内强劲地喷射。因此，能将泼了喷射的水的洗涤物S通过充分地搅拌，有效地进行清洗。
由于所有的出口22都朝向圆周方向Y配置，因而能将通过流路26汲上来的水从出口22向圆周方向Y喷出。由此，能够通过向圆周方向Y喷出的水，将洗涤槽4内的洗涤物S以向圆周方向Y进行旋转的方式一边搅拌一边进行清洗。
如上所述，在洗衣机1中，叶轮13如图1所示，以与洗涤物S隔离的方式设置在洗涤槽4的底部4D。特别是，由于分隔构件9将洗涤槽4的内部空间10分隔为配置洗涤物S的第一空间11和配置叶轮13的第二空间120，因而将叶轮13与洗涤物S可靠地隔离开来。因此，由于即使叶轮13为了将水送入而进行旋转，洗涤物S也不会不与叶轮13摩擦，因而能防止洗涤物S的损伤。
此外，在通过分隔构件9将叶轮13与洗涤物S隔离开来的结构中，由于能 使叶轮13高速地旋转，因而能将在抽水路20的流路26内汲上来的水的势头增强，使水从出口22更加强劲地喷射到洗涤槽4内，将洗涤物S充分搅拌。进而，由于第二空间12为在洗涤槽4的底壁4C形成的上下窄的凹部4G，因而能够确保使其上方X1的第一空间11(洗涤物S的容量)尽可能地大。
如上所述，该洗衣机1不是通过现有的波轮，而是通过从简单结构的抽水路20喷出的水的强力且复杂的流动，在不擦伤洗涤物S的情况下使洗涤物剧烈运动进行清洗。由此，能在防止洗涤物S的损伤的同时，将洗涤物S有效地进行清洗。此外，由于洗涤槽4内的水通过经由抽水路20的流路26进行循环从而能反复地用于洗涤，因而可以用较少的水进行洗涤。
本发明并不局限于以上所说明的实施方式，可以在权利要求记载的范围内进行各种变更。
图8是本发明的第一变形例的洗衣机的内部构造的纵剖视图。在图8中，为了方便说明，省略了上述分隔构件9的图示。图9是图8的C-C向视剖视图。图10是图9的D-D向视剖视图。
例如，在上述实施方式中，虽然在各个抽水路20，在圆周方向Y上的两侧设置了出口22，但是出口22如由图8～图10表示的第一变形例所示，也可以只设置在圆周方向Y上的单侧。在这种情况下，在抽水路20的主体部21，省略了出口22的那一侧的弯曲部21C从径向内侧Z1观察，构成以往出口22靠近的方式相对于上下方向X倾斜的倾斜构件40。
由于出口22在各个抽水路20中设置于圆周方向Y上的单侧，因而在圆周方向Y上并排配置有多个抽水路20的情况下，能防止从相邻抽水路20的出口22喷出的水相互碰撞而失势。当然，此时，在各个抽水路20，出口22需要设置在同一侧。
如图10所示，抽水路20的流路26通过倾斜构件40，从入口25越往出口22越窄。由此，能将从入口25抽取并通过流路26汲上来的水的流速越往出口22越是加快。因此，能将汲上来的水从出口22更加强劲地喷射到洗涤槽4内。因此，能将泼了喷射的水的洗涤物S通过充分地搅拌有效地进行清洗。
具体地，在图10中，在叶轮13向逆时针方向Y2旋转，出口22为上述下游侧出口22A的情况下，通过流路26汲上来的水在碰撞到闭塞构件27上之前，从下游侧出口22A向逆时针方向Y2且向斜上方强劲地喷出(参照粗实线箭头)。 另一方面，在图10所示的出口22为上述上游侧出口22B的情况下，通过流路26汲上来的水通过碰撞到闭塞构件27上，从上游侧出口22B向逆时针方向Y2且向斜下方强劲地喷出(参照粗的虚线箭头)。
图11是本发明的第二变形例的洗衣机的内部构造的纵剖视图。在如第一变形例所示将出口22设置于抽水路20的单侧的情况下，如图11所示，也可以省略分隔构件9，设置惯用的波轮45来代替叶轮13。在这种情况下，将相当于叶轮13的叶片13B的背叶片45A设置于波轮45的下面，在波轮45旋转时，背叶片45A将存积于洗涤槽4的水送入抽水路20的入口25。
由于波轮45与洗涤槽4内的洗涤物S接触，因而为了不损伤洗涤物S，最好以比叶轮13更低的速度进行旋转。在这种情况下，洗涤物S除了通过低速旋转的波轮45轻柔地进行搅拌之外，还通过从抽水路20喷出的水(参照粗实线)的势头进行搅拌。由此，能在防止因波轮45而导致洗涤物S损伤的同时，将洗涤物S更有效地进行清洗。当然，如图11所示，也可以将出口22设置于抽水路20的两侧。
此外，抽水路20的主体部21为盖状，流路26为划分成主体部21的背面21A、背面21A的一对筋21E、以及洗涤槽4的内周面4F的空间。换句话说，严格来说流路26是由抽水路20和洗涤槽4的内周面4F合力构成的。备选地，也可以采用主体部21为中空体，并通过由该中空部分构成流路26，从而抽水路20单独构成流路26的结构。
