Description

双桶式洗衣机 技术领域
本发明涉及一种双桶式洗衣机。
背景技术
下述专利文献1所记载的双桶式洗衣机包括：洗涤桶；以及溢水口罩，装接于洗涤桶的侧壁的局部以形成溢水室。当洗涤桶内的水位上升至规定水位时，洗涤桶内的水会溢至溢水室而向机外排出。
虽然专利文献1中没有具体的记载，但双桶式洗衣机通常包括用于将从洗涤桶内溢至溢水室的水向机外排出的溢水路。这样的溢水路具有配置于溢水室的伸缩部，在伸缩部设有用于将溢水室内的水摄入溢水路内的入口。此外，在溢水口罩设有能在上下方向上滑动的滑动构件。滑动构件具有：提纽部，向洗涤桶内露出；以及保持部，对配置于溢水室内的伸缩部进行保持。当用户捏住提纽部使其在上下方向上移动时，滑动构件滑动。如此，由保持部保持的伸缩部在上下方向上伸缩，因此入口的高度位置被变更。由此，能调整要从溢水室向机外排出洗涤桶内的水时的洗涤桶内的水位。
在这样的结构中，在溢水口罩中面向溢水室内的背面部设有在上下方向上并排的多个肋。滑动构件具有卡合于肋的定位部。当用户使滑动构件滑动以便变更溢水路的伸缩部的入口的高度位置时，定位部翻越肋。当用户使滑动构件停止滑动时，定位部嵌入多个肋当中上下方向上相邻的两个肋之间，因此滑动构件在上下方向上被定位。由此，维持变更后的入口的高度位置。
现有的定位部是与溢水口罩的肋平行地延伸的爪，刚性较高。另一方面，各个肋一定程度上会在成形时存在尺寸等偏差。在相邻的肋的间隔因偏差等而变大的情况下，滑动构件的定位松弛，因此滑动构件会随着洗涤桶内的水位的升降而随意滑动。考虑到这样的偏差，现有的定位部成形地较大以便紧紧地嵌入相邻的横肋之间。因此，虽然能将滑动构件以不会随意滑动的方式牢固地定 位，但滑动构件的滑动僵硬。因此，对于要使滑动构件滑动的用户而言，操作性差。

发明内容
发明所要解决的问题
本发明是基于该背景而完成的，其目的在于提供一种能谋求对溢水路的伸缩部进行保持的滑动构件的定位的可靠性和操作性的提高的双桶式洗衣机。
用于解决问题的方案
本发明是一种双桶式洗衣机，包括：洗涤桶，具有在上下方向上延伸的内面部，用于洗涤洗涤物，所述洗涤桶具有溢水口和溢水室，所述溢水口设于所述内面部，所述溢水室接纳从所述洗涤桶内经过所述溢水口的水；脱水桶，以与所述洗涤桶横向并排的方式配置，用于将洗涤物脱水；溢水口罩，装配于所述溢水口，设有纵肋和多个横肋，所述纵肋从所述溢水口罩中的面向所述溢水室内的背面部向所述溢水室内突出，在上下方向上延伸，所述多个横肋设于所述纵肋，在所述纵肋的突出方向上延伸，在上下方向上并排；排水路，连接于所述洗涤桶中比所述溢水口靠下侧的部分，排出所述洗涤桶内的水；溢水路，具有配置于所述溢水室内并能在上下方向上伸缩的伸缩部，从设于所述伸缩部的入口将所述溢水室内的水摄入并将其导向所述排水路；以及滑动构件，以能在上下方向上滑动的方式由所述溢水口罩支承，所述滑动构件具有：提纽部，配置于所述溢水口罩中与所述背面部相反侧的表面部，向所述洗涤桶内露出，被操作以使所述滑动构件滑动；保持部，配置于所述溢水室内，保持所述伸缩部；以及定位部，通过嵌入所述多个横肋当中上下方向上相邻的两个横肋之间，将所述滑动构件在上下方向上定位，所述定位部具有：主体部，以向所述纵肋侧鼓出的方式弯曲，嵌入所述两个横肋之间；以及支承部，以向与所述纵肋侧相反侧鼓出的方式弯曲，支承所述主体部。
此外，本发明的特征在于，所述支承部设于上下方向上的所述主体部的两侧。
此外，本发明的特征在于，所述提纽部在上下方向上配置于所述定位部与所述保持部之间。
此外，本发明的特征在于，从上下方向观察时，嵌入所述两个横肋之间时的所述主体部以与所述突出方向上的该横肋的大致整个区域重叠的方式配置。
此外，本发明的特征在于，在所述定位部设有从所述背面部侧将所述支承部切口出的缺口，所述支承部在所述突出方向上比所述主体部窄。
发明效果
根据本发明，当用户使滑动构件在上下方向上滑动以便变更溢水路中由滑动构件的保持部保持的伸缩部的入口的高度位置时，滑动构件的定位部翻越设于溢水口罩的背面部上的纵肋的多个横肋。当用户使滑动构件停止滑动时，定位部嵌入多个横肋当中上下方向上相邻的两个肋之间，因此滑动构件在上下方向上被定位。由此，维持变更后的入口的高度位置。
该定位部具有：主体部，硬嵌入两个肋之间；以及支承部，支承主体部，主体部以向纵肋侧鼓出的方式弯曲，支承部以向与纵肋侧相反侧鼓出的方式弯曲，因此主体部和支承部双方能弹性变形。因此，即使上下方向上相邻的横肋的间隔因偏差等而变大，主体部也会以向上下方向伸展的方式弹性变形，紧紧地嵌入这些横肋之间，因此能将滑动构件以不会随意滑动的方式牢固地定位。另一方面，当用户捏住提纽部要使滑动构件滑动时，通过主体部和支承部双方弹性变形，主体部从相邻的横肋之间顺畅地离开，顺畅地翻越横肋，因此用户能使滑动构件顺畅地滑动。以上的结果是，能谋求滑动构件的定位的可靠性和操作性的提高。
此外，根据本发明，即使用户捏住提纽部要使滑动构件向上侧和下侧中的任一侧滑动，由于设于上下方向上的主体部的两侧的支承部会弹性变形，因此主体部也会从相邻的横肋之间顺畅地离开，顺畅地翻越横肋。因此，能使滑动构件向上侧和下侧中的任一侧均顺畅地滑动，因此能谋求滑动构件的操作性的进一步提高。
此外，根据本发明，提纽部在上下方向上配置于定位部与保持部之间这一平衡量好的位置，因此对于用户而言，容易捏住提纽部来使其移动。因此，能谋求滑动构件的操作性的进一步提高。
此外，根据本发明，从上下方向观察时，嵌入两个横肋之间时的定位部的主体部以与溢水口罩的背面部的纵肋的突出方向上的该横肋的大致整个区域重叠的方式配置。由此，夹在两个横肋之间的主体部会通过大范围地与这些横肋接触而更紧地嵌入这些横肋之间，因此能将滑动构件以不会随意滑动的方式进一步牢固地定位。因此，能谋求滑动构件的定位的可靠性的进一步提高。
此外，根据本发明，通过在定位部设有从溢水口罩的背面部侧将支承部切口出的缺口，支承部在纵肋的突出方向上比主体部窄，因此能有意地使主体部中比支承部向背面部侧突出的根部分的刚性降低。
当用户使滑动构件滑动时，滑动构件的定位部一边使纵肋和多个横肋挠曲一边翻越纵肋和多个横肋。此时，在各个纵肋和横肋中，与背面部侧的基端部相反侧的前端部挠曲，而定位部的主体部中刚性设定得低的根部分会被纵肋的基端部推着向与纵肋的前端部相反的方向挠曲，由此整个主体部成为与挠曲的纵肋和横肋大致平行的姿势。由此，滑动构件停止滑动并夹在两个横肋之间时的主体部会通过大范围地与这些横肋接触而更紧地嵌入这些横肋之间，因此能将滑动构件以不会随意滑动的方式进一步牢固地定位。因此，能谋求滑动构件的定位的可靠性的进一步提高。

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1是本发明的一个实施方式的双桶式洗衣机1的示意性纵剖主视图。需要说明的是，以下，将图1中的上下方向称为双桶式洗衣机1的上下方向Z，上下方向Z当中，将上侧称为上侧Z1，将下侧称为下侧Z2。关于左右方向，基于各图的纸面的左右方向来确定双桶式洗衣机1和双桶式洗衣机1的组件的方向。因此，某个图中的左右方向有时会成为与其他图中的左右方向相反的方向。
双桶式洗衣机1包括：箱体2，构成双桶式洗衣机1的外轮廓；洗涤桶3，配置于箱体2内；旋转翼4，容纳于洗涤桶3内；电动马达5，使旋转翼4旋转；外桶6，在箱体2内以与洗涤桶3横向并排的方式配置；脱水桶7，配置于外桶6内；以及电动马达8，使脱水桶7旋转。
箱体2例如为金属制，形成为箱状。在箱体2的上表面2A，以在左右方向上横向并排的方式形成有使箱体2内外连通的第一开口2B和第二开口2C。第一开口2B配置于比第二开口2C靠左侧处。在上表面2A设有将第一开口2B开 闭的第一门9A和将第二开口2C开闭的第二门9B。在上表面2A中比第一开口2B和第二开口2C靠里侧处设有由触摸面板等构成的显示操作部10。
洗涤桶3在本实施方式中配置于箱体2的内部空间中的左区域。洗涤桶3形成为有底圆筒状，具有：大致圆筒状的圆周壁3A，沿上下方向Z配置；圆环状的环状壁3B，一边将圆周壁3A的上端缘包边一边向圆周壁3A的圆心侧突出；以及底壁3C，从下侧Z2堵住圆周壁3A的中空部分。洗涤桶3具有穿过其圆心在上下方向Z上延伸的中心轴J。将以中心轴J为基准的径向称为径向R。径向R当中，将远离中心轴J的方向称为径向外侧R1，将靠近中心轴J的方向称为径向内侧R2。
圆周壁3A的内周面是洗涤桶3中在上下方向Z上延伸的内面部3D。在内面部3D的上下方向Z上的中途设有溢水口3E。溢水口3E是纵向长的开口。在圆周壁3A设有一边将溢水口3E包边一边向横向突出的中空的突出部3F。突出部3F的内部空间是从溢水口3E向横向，具体而言在图1中向右侧凹陷的溢水室3G。以下，将溢水室3G视为与洗涤桶3内即洗涤桶3的内部空间3H不同的空间。溢水室3G相对于内部空间3H配置于径向外侧R1，处于经由溢水口3E与内部空间3H连通的状态。
在环状壁3B的内侧形成有从上侧Z1与圆周壁3A的中空部分连通的出入口3I。出入口3I处于从下侧Z2与箱体2的第一开口2B对置并连通的状态。在环状壁3B设有对出入口3I进行开闭的盖11。用户打开第一门9A和盖11使第一开口2B和出入口3I敞开，使洗涤物L1出入于洗涤桶3。底壁3C形成为大致水平地延伸的圆板状，在底壁3C的圆心位置形成有贯通底壁3C的贯通孔3J。
双桶式洗衣机1还包括：供水路12，与龙头相连；供水阀13，设于供水路12的中途；排水路14，被拉出至机外即箱体2之外；以及排水阀15，设于排水路14的中途。
供水路12分支为第一支路12A和第二支路12B，第一支路12A从上侧Z1与环状壁3B连接。第二支路12B与外桶6连接。在供水路12中第一支路12A与第二支路12B的分支位置设有切换构件16。切换构件16与配置于箱体2的上表面2A中显示操作部10的周边的杆(未图示)的操作相应地使来自龙头的自来水流过第一支路12A和第二支路12B中的任一方。流过第一支路12A的自来 水向洗涤桶3供给并蓄于洗涤桶3内。当洗涤桶3内的水位超过洗涤桶3的圆周壁3A的溢水口3E的下端时，洗涤桶3内的水经过溢水口3E流向溢水室3G，被接纳至溢水室3G内。供水阀13在供水路12中设于比分支位置靠近龙头的上游部12C，为了开始供水或停止供水而开闭。
排水路14连接于洗涤桶3中比溢水口3E靠下侧Z2的部分，具体而言连接于底壁3C，将洗涤桶3内的水向机外排出。排水阀15为了开始排水或停止洗涤桶3的排水而开闭。
双桶式洗衣机1还包括：溢水路20，用于将溢水室3G内的水排出；溢水口罩21，装配于溢水口3E；以及滑动构件22，以能在上下方向Z上滑动的方式由溢水口罩21支承。
溢水路20具有作为其上端部配置于溢水室3G内的伸缩部20A。溢水路20从伸缩部20A贯通洗涤桶3的突出部3F的下壁3K向下侧Z2延伸，连接于排水路14中比排水阀15靠近机外的下流侧的部分。需要说明的是，下壁3K与溢水路20的间隙被密封以便不漏水。伸缩部20A例如由波纹管构成，能在上下方向Z上伸缩。在伸缩部20A设有入口20B。作为一个例子，入口20B设于伸缩部20A的上端，处于朝上侧Z1开口的状态。溢水路20中比伸缩部20A靠近排水路14的下流部20C既可以与伸缩部20A同样地由波纹管构成，也可以由虽然没有波纹但具有挠性的软管构成。
溢水口罩21形成为纵向长的板状。溢水口罩21从径向内侧R2覆盖溢水室3G。在该状态的溢水口罩21中，径向内侧R2的表面部21A面向洗涤桶3内，径向外侧R1的背面部21B面向溢水室3G内。表面部21A配置于溢水口罩21中与背面部21B相反侧处。在溢水口罩21形成多个沿板厚方向即径向R贯通溢水口罩21的狭缝状的通水孔21C。从洗涤桶3内经过溢水口3E流入溢水室3G内的水严格来讲经过通水孔21C流入溢水室3G内。关于溢水口罩21，在下文中进行详细说明。
滑动构件22具有：提纽部23，配置于溢水口罩21的表面部21A，向洗涤桶3内露出；以及保持部24，配置于溢水室3G内，对溢水路20的伸缩部20A进行保持。用户从箱体2的第一开口2B和洗涤桶3的出入口3I探到滑动构件22来捏住提纽部23将其向上下方向Z操作，由此能使整个滑动构件22在上下 方向Z上滑动。与滑动构件22的滑动相应地，伸缩部20A在上下方向Z上伸缩，因此伸缩部20A的入口20B的高度位置被变更。关于滑动构件22，也在下文中进行详细说明。
旋转翼4是所谓的波轮，形成为以中心轴J为圆心的圆盘状，配置于洗涤桶3的底壁3C上。在旋转翼4设有从其圆心沿中心轴J向下侧Z2延伸的旋转轴30。旋转轴30的下端部穿过底壁3C的贯通孔3J而位于比底壁3C靠下侧Z2并与马达5连接。当马达5工作时，马达5的驱动力被传递给旋转轴30而使旋转翼4旋转。
外桶6在本实施方式中配置于箱体2的内部空间中的右区域，从右侧与洗涤桶3并排。外桶6形成为在上端具有出入口6A的有底圆筒状。出入口6A处于从下侧Z2与箱体2的第二开口2C对置并连通的状态。在外桶6设有对出入口6A进行开闭的盖31。在外桶6的底壁的圆心位置形成有在上下方向Z上贯通该底壁的贯通孔6B。
脱水桶7形成为比外桶6小一圈的有底圆筒状，同轴状地容纳于外桶6内。脱水桶7能在内部容纳洗涤物L2。在脱水桶7的上端形成有出入口7A。出入口7A处于从下侧Z2与外桶6的出入口6A和箱体2的第二开口2C连通的状态。用户打开第二门9B和盖31使第二开口2C、出入口6A以及出入口7A敞开，使洗涤物L2出入于脱水桶7。
容纳于外桶6内的状态的脱水桶7能绕在上下方向Z上延伸的中心轴(未图示)旋转。在脱水桶7形成有多个贯通孔7B。在脱水桶7的底壁设有沿脱水桶7的中心轴向下侧Z2延伸出的旋转轴33。旋转轴33的下端部穿过外桶6的底壁的贯通孔6B而位于比底壁靠下侧Z2并与马达8连接。当马达8工作时，马达8的驱动力被传递给旋转轴33而使脱水桶7旋转。
上述的供水路12的第二支路12B从上侧Z1与外桶6的上部连接，从上侧Z1面向脱水桶7的出入口7A。外桶6的底壁和排水路14中比与溢水路20的连接部分靠近机外的下流侧的部分通过流出路32相连。流过第二支路12B的自来水从出入口7A流入脱水桶7内后，经过流出路32从外桶6流出并流过排水路14向机外排出。
双桶式洗衣机1还包括由微机等构成的控制部40。马达5、马达8、显示操作部10、供水阀13以及排水阀15分别与控制部40电连接。控制部40通过控制马达5、供水阀13以及排水阀15的动作来执行洗涤运转。洗涤运转包括：清洗过程，在洗涤桶3内对洗涤物L1进行洗涤；以及漂洗过程，在洗涤桶3内对洗涤物L1进行漂洗。洗涤运转中既可以连续地执行清洗过程和漂洗过程，也可以仅执行清洗过程和漂洗过程中的任一个。控制部40通过控制马达8和供水阀13的动作来执行对脱水桶7内的洗涤物L2进行脱水的脱水运转。
在洗涤运转的情况下，用户事先操作上述的杆以使来自龙头的自来水流过供水路12中的第一支路12A(未图示)。在脱水运转的情况下，用户事先操作杆以使来自龙头的自来水流过供水路12中的第二支路12B。
当将洗涤物L1投入洗涤桶3并关闭了第一门9A和盖11的用户操作显示操作部10来指示执行清洗运转的清洗过程时，控制部40首先通过在关闭了排水阀15的状态下将供水阀13打开规定时间来向洗涤桶3内供水。也可以是，在供水前或供水后的时刻，用户打开第一门9A来将洗涤剂投入洗涤桶3内。
当洗涤桶3内的水位上升至比溢水路20的入口20B低的规定的上限水位时，控制部40在关闭供水阀13停止供水后通过使马达5工作来使旋转翼4旋转。在洗涤桶3内位于比溢水口3E高的位置的一部分水处于经过溢水口罩21的通水孔21C流入了溢水室3G内的状态，处于洗涤桶3的内部空间3H中的水位与溢水室3G中的水位一致的状态。通过旋转翼4的旋转，洗涤桶3内的洗涤物L1通过被搅拌或由洗涤剂分解污垢而被洗浄。最后，控制部40通过使马达5停止并打开排水阀15来将洗涤桶3排水。由此，清洗过程结束。
漂洗过程中有在向洗涤桶3内蓄留自来水至上述的上限水位的状态下漂洗洗涤物L1的“蓄水漂洗过程”和一边从供水路12向洗涤桶3内一直供水一边漂洗洗涤物L1的“注水漂洗过程”。在蓄水漂洗过程中，控制部40首先通过在关闭了排水阀15的状态下将供水阀13打开规定时间来将向洗涤桶3内蓄留自来水。完成了供水的控制部40通过使马达5工作来使旋转翼4旋转。由此，对洗涤桶3内的洗涤物Q进行漂洗。
在注水漂洗过程中，控制部40首先通过在关闭了排水阀15的状态下打开供水阀13来向洗涤桶3供水。当洗涤桶3内的水位上升至比溢水口3E的下端 高时，洗涤桶3内的水经过溢水口罩21的通水孔21C流入溢水室3G内。洗涤桶3内的水位与溢水室3G内的水位一致。而且，即使洗涤桶3内的水位上升至溢水路20的入口20B，供水阀13也处于持续打开的状态，因此从洗涤桶3内流入溢水室3G的水会通过从入口20B被摄入溢水路20内而向洗涤桶3之外溢出。摄入溢水路20内的水在溢水路20内落下并被导向排水路14。在溢水路20内落下并到达排水路14的水从排水路14向机外排出。像这样，入口20B的高度位置是开始从洗涤桶3溢水时的高度位置，以下称为“溢水高度”。
像这样，在注水漂洗过程中，通过持续向洗涤桶3供水和从溢水路20溢流来一直更换洗涤桶3内的水，在该状态下，控制部40通过使马达5工作而使旋转翼4旋转来对洗涤桶3内的洗涤物L1进行漂洗。在注水漂洗过程中，在洗涤物L1量多的情况下，用户事先捏住滑动构件22的提纽部23来使滑动构件22向上侧Z1滑动，将溢水路20的入口20B预先配置于高位置，以便所有的洗涤物L1浸入洗涤桶3内的水中。在洗涤物L1量少的情况下，用户事先捏住提纽部23来使滑动构件22向下侧Z2滑动，将溢水路20的入口20B预先配置于低位置以便节水。在本实施方式中，将入口20B的高度位置即溢水高度调整为最高的“高位置”、最低的“低位置”以及高位置与低位置之间的“中位置”的三阶。需要说明的是，溢水高度既可以在三阶以外阶段性地调整，也可以无阶调整。
在蓄水漂洗过程和注水漂洗过程中的任一过程中，在供水的前后或中途的时刻，用户都可以打开第一门9A来将柔顺剂投入洗涤桶3内。柔顺剂渗入洗涤物L1。最后，控制部40使马达5停止，将洗涤桶3排水。
当将洗涤物L2投入脱水桶7并关闭了第二门9B和盖31的用户操作显示操作部10来指示执行脱水运转时，控制部40通过使马达8工作来使脱水桶7以规定的脱水转速旋转。由此，脱水桶7内的洗涤物L2通过离心力作用而被脱水。需要说明的是，洗涤物L2也可以是刚完成洗涤运转并由用户从洗涤桶3转移至脱水桶7的洗涤物L1。此外，控制部40也可以在脱水运转中打开供水阀13来向脱水桶7内供水。由此，对脱水桶7内的洗涤物L2进行脱水。
接着，依次对溢水口罩21和滑动构件22进行详细说明。图2是从径向内侧R2观察溢水口罩21和滑动构件22的立体图。在溢水口罩21的例如下端、 左缘的上端部以及右缘的上端部均设有卡合于洗涤桶3的圆周壁3A的爪状的卡合部50。在溢水口罩21的表面部21A的上端部设有向径向内侧R2突出的横向长的抓持部51。在将溢水口罩21拆装于溢水口3E时，用户抓住抓持部51。在表面部21A的大致下半边设有向径向外侧R1凹陷的纵向长的凹部52。在凹部52装配有在洗涤运转中捕获从洗涤物L1中去除的棉绒等异物的过滤器(未图示)。
在表面部21A的大致上半边，具体而言，在抓持部51与凹部52之间的区域设有向径向外侧R1凹陷的纵向长的槽53。在槽53的槽底53A形成有在上下方向Z上细长地延伸并在径向R上贯通槽底53A的狭缝53B。上述的多个通水孔21C在上下方向Z上并排，由此形成在上下方向Z上并排的列。在上下方向Z上并排的凹部52和槽53的左右两侧逐一配置有一列通水孔21C的列。各个通水孔21C例如为横向长的狭缝。所有的通水孔21C的形状和大小既可以相同，也可以像本实施方式那样，凹部52的周边的通水孔21C在左右方向上比槽53的周边的通水孔21C窄。
在表面部21A的大致上半边中左右方向上的槽53的两侧显示有分别表示上述的“高位置”、“中位置”以及“低位置”的标识M1。在本实施方式中，槽53的左侧的标识M1是英语标记，槽53的右侧的标识M1是日语标记。需要说明的是，在溢水口罩21的背面部21B设有当溢水高度位于高位置时与滑动构件22接触的止动件21D，以便滑动构件22无法进一步上升(参照后述的图11)。
图3是从径向外侧R1观察溢水口罩21和滑动构件22的立体图。在溢水口罩21的背面部21B的上端部设有位于上述的抓持部51(参照图2)的背侧并向径向内侧R2凹陷的横向长的凹部54。在背面部21B的大致下半边设有位于上述的凹部52(参照图2)的背侧并向径向外侧R1突出的纵向长的凸部55。在背面部21B的大致上半边，具体而言，在凹部54与凸部55之间的区域配置有上述的槽53的槽底53A。在背面部21B中，在上下方向Z上并排的凸部55和槽底53A的左右两侧中避开通水孔21C的位置设有多个在左右方向上延伸的加强肋56。
在溢水口罩21的背面部21B设有从槽53的槽底53A的左缘和右缘分别向径向外侧R1即向溢水室3G内突出的彼此平行的左右一对纵肋57。左右一对纵 肋57当中，在图3中位于左侧的纵肋57A沿槽底53A的左缘在上下方向Z上延伸，在图3中位于右侧的纵肋57B沿槽底53A的右缘在上下方向Z上延伸。在左右一对纵肋57之间形成有在上下方向Z上延伸的引导槽58。槽53的槽底53A兼作引导槽58的槽底。
在这些纵肋57的彼此对置的对置面即纵肋57A的右表面和纵肋57B的左表面各自的大致整个区域设有在上下方向Z上等间隔地并排的多个横肋59。各个横肋59配置于引导槽58内，在纵肋57的突出方向即径向外侧R1上延伸。设于左侧的纵肋57A的右表面的各横肋59的纵剖面形成为向右侧鼓出的半圆状，各横肋59中径向外侧R1的端面与纵肋57A中径向外侧R1的端面位于同一平面。设于纵肋57B的左表面的各横肋59的纵剖面形成为向左侧鼓出的半圆状，各横肋59中径向外侧R1的端面与纵肋57A中径向外侧R1的端面位于同一平面。
在槽53的槽底53A设有在引导槽58内从狭缝53B的左缘和右缘分别向径向外侧R1突出的彼此平行的左右一对引导肋60。左右一对引导肋60当中，左侧的引导肋60沿狭缝53B的左缘在上下方向Z上延伸，右侧的引导肋60沿狭缝53B的右缘在上下方向Z上延伸。各引导肋60中径向外侧R1的端部位于比纵肋57中径向外侧R1的端部靠径向内侧R2处。

连结部71具有：平板部71A，配置于比基座部70的表面部70D靠径向内侧R2处；以及柱状部71B，将表面部70D和平板部71A相连。平板部71A与 表面部70D平行地配置。在平板部71A中径向内侧R2的表面显示有表示滑动构件22的滑动方向的标识M2。柱状部71B呈纵向细长的长方体柱状，架设于左右方向上的表面部70D的中央部与左右方向上的平板部71A的中央部之间。
提纽部23形成为从平板部71A的下端向径向内侧R2弯折的板状。保持部24与基座部70的上端部连结，在图4中从基座部70的上端部向径向外侧R1且向右侧突出地配置。保持部24在俯视观察时弯曲成大致C字状，其开放部24A朝径向外侧R1配置。溢水路20的伸缩部20A从开放部24A嵌入保持部24内。保持部24夹持伸缩部20A对其进行保持。伸缩部20A的入口20B配置于比保持部24靠上侧Z1处。
图5是从径向内侧R2观察的滑动构件22的主视图。定位部72设有左右一对，在基座部70的中途部70C的左右方向上的两侧逐一配置有一个。这些定位部72以中途部70C为基准左右对称地配置。左右一对定位部72当中，在图5中位于右侧的定位部72A架设于基座部70中主体部70A的下端面的右端与基座部70中下端部70B的上端面的右端之间。左右一对定位部72当中，在图5中位于左侧的定位部72B架设于主体部70A的下端面的左端与下端部70B的上端面的左端之间。

图8是从径向外侧R1观察的溢水口罩21和滑动构件22的后视图。图9是包含图8的A－A向视剖面的主要部分立体图。在处于由溢水口罩21支承的状态的滑动构件22中，提纽部23和连结部71的平板部71A配置于溢水口罩21的表面部21A的槽53内，连结部71的柱状部71B配置于槽53的槽底53A的狭缝53B内(参照图2和后述的图11)。此外，保持部24、基座部70以及定位部72配置于溢水口罩21的背面部21B。基座部70中径向内侧R2的部分和左右一对定位部72的大部分配置于背面部21B上的左右一对纵肋57之间的引导槽58内。基座部70的下端部70B上的左右一对爪部70E在引导槽58内隔着狭缝53B配置。
图10是图9中由双点划线包围的主要部分的放大图。基座部70的中途部70C处于从径向外侧R1与槽53的槽底53A的狭缝53B和设于狭缝53B的左右的缘的引导肋60对置的状态。左右一对定位部72当中，在图10中位于左侧的定位部72A处于从右侧与左右一对纵肋57中左侧的纵肋57A邻接的状态，在图10中位于右侧的定位部72B处于从左侧与左右一对纵肋57中右侧的纵肋57B邻接的状态。
在左侧的定位部72A中，主体部72C处于向纵肋57A侧鼓出即图10中向左侧鼓出的状态，相对于主体部72C位于上下两侧的支承部72D各自处于向与纵肋57A侧相反侧鼓出即图10中向右侧鼓出的状态(还参照图8)。在右侧的定位部72B中，主体部72C处于向纵肋57B侧鼓出即图10中向右侧鼓出的状态，相对于主体部72C位于上下两侧的支承部72D各自处于向与纵肋57B侧相 反侧鼓出即图10中向左侧鼓出的状态(还参照图8)。
在图10中，定位部72A的主体部72C处于嵌入纵肋57A上多个横肋59当中上下方向Z上相邻的两个横肋59之间的状态，并且定位部72B的主体部72C处于嵌入纵肋57B上多个横肋59当中上下方向Z上相邻的两个横肋59之间的状态(还参照图8)。由此，整个滑动构件22处于在上下方向Z上被定位的状态。需要说明的是，在该状态下，滑动构件22中定位部72B以外的部分与溢水口罩21不接触。但是，当溢水高度位于高位置时，设于溢水口罩21的背面部21B的引导槽58的槽底的上部的止动件21D从上侧Z1与滑动构件22的基座部70的下端部70B处的爪部70E接触(参照图8)。
图11是图8的A－A向视剖视图。图12是图11的主要部分的示意性放大图。在各个定位部72A和定位部72B中，从上下方向Z即与图12的纸面垂直的方向观察，嵌入上下方向Z上相邻的两个横肋59之间时的主体部72C以与纵肋57的突出方向一致或大致一致的径向R上的该横肋59的大致整个区域重叠的方式配置。
为了变更溢水路20中由滑动构件22的保持部24保持的伸缩部20A的入口20B的高度位置，当用户使滑动构件22在上下方向Z上滑动时，滑动构件22的各定位部72翻越设于对应的纵肋57的多个横肋59。当用户使滑动构件22停止滑动时，定位部72嵌入多个横肋59当中上下方向Z上相邻的两个肋之间，因此滑动构件22在上下方向Z上被定位。由此，维持变更后的入口20B的高度位置即上述的溢水高度。
定位部72一体地具有：主体部72C，以向纵肋57侧鼓出的方式弯曲，硬嵌入两个横肋59之间；以及支承部72D，以向与纵肋57侧相反侧鼓出的方式弯曲，支承主体部72C。在这样的定位部72中，主体部72C和支承部72D的双方能弹性变形。因此，即使上下方向Z上相邻的横肋59的间隔因偏差等而变大，主体部72C也会以在上下方向Z上伸展的方式弹性变形，一边吸收该偏差，一边紧紧地嵌入这些横肋59之间(还参照图8)。因此，即使对滑动构件22作用洗涤桶3内的水的浮力、在溢水路20的伸缩部20A伸缩时产生的复原力等，也能将滑动构件22以不会随意滑动的方式牢固地定位。
另一方面，当用户捏住提纽部23要使滑动构件22滑动时，主体部72C和 支承部72D的双方弹性变形。由此，主体部72C尤其能在左右方向上大幅划过。因此，主体部72C会从相邻的横肋59之间顺畅地离开并顺畅地翻越横肋59，因此，用户能以一定的轻力使滑动构件22顺畅地滑动。以上的结果是，能谋求滑动构件22的定位的可靠性和操作性的提高。
此外，即使用户捏住提纽部23而要使滑动构件22向上侧Z1和下侧Z2中的任一侧滑动，由于设于上下方向Z上的主体部72C的两侧的支承部72D弹性变形，主体部72C也会从相邻的横肋59之间顺畅地离开，顺畅地翻越横肋59。因此，能使滑动构件22向上侧Z1和下侧Z2中的任一侧均顺畅地滑动，因此能谋求滑动构件22的操作性的进一步提高。
而且，提纽部23在上下方向Z上配置于定位部72与保持部24之间这一平衡良好的位置，因此对于用户而言，容易捏住提纽部使其移动。因此，能谋求滑动构件22的操作性的进一步提高。
此外，从上下方向Z观察时，夹在两个横肋59之间时的定位部72的主体部72C延伸至溢水口罩21的背面部21B侧即横肋59的基端部59A。因此，从上下方向Z观察时，主体部72C以与溢水口罩21的背面部21B的纵肋57的突出方向即径向R上的该横肋59的整个区域重叠的方式配置。由此，夹在两个横肋59之间的主体部72C通过大范围地与这些横肋59接触而更紧地嵌入这些横肋59之间，因此能将滑动构件22以不会随意滑动的方式进一步牢固地定位。因此，能谋求滑动构件22的定位的可靠性的进一步提高。
此外，通过在定位部72设有从溢水口罩21的背面部21B侧将支承部72D切口出的缺口73，支承部72D在纵肋57的突出方向上比主体部72C窄，因此能有意地使主体部72C中比支承部72D向背面部21B侧突出的根部分72E的刚性降低。需要说明的是，虽然也能通过调整定位部72的厚度来降低根部分72E的刚性，但与调整定位部72的厚度相比，形成缺口73的方式能更准确且可靠地降低根部分72E的刚性。
当用户使滑动构件22滑动时，滑动构件22的定位部72如图12所示一边使纵肋57和多个横肋59向左右方向挠曲一边翻越纵肋57和多个横肋59。此时，在各个纵肋57和横肋59中，与背面部21B侧的基端部57C和59A相反侧的前端部57D和59B挠曲，左右一对纵肋57在前端部57D侧张开。如此，主体部 72C中刚性设定得低的根部分72E会被纵肋57的基端部57C推着向与纵肋57的前端部57D相反的方向(参照图12的箭头Y)挠曲。由此，整个主体部72C成为与挠曲的纵肋57和横肋59大致平行的姿势。
因此，滑动构件22停止滑动并夹在两个横肋59之间时的主体部72C通过大范围地与这些横肋59接触而更紧地嵌入这些横肋59之间，因此能将滑动构件22以不会随意滑动的方式进一步牢固地定位。因此，能谋求滑动构件22的定位的可靠性的进一步提高。需要说明的是，主体部72C的前端部分72F的径向R的宽度W1与根部分72E的径向R的宽度W2优选为1比1以上且3比2以下的关系，以使整个主体部72C成为与挠曲的纵肋57和横肋59大致平行的姿势。
本发明不限定于以上说明的实施方式，可以在技术方案所记载的范围内进行各种变更。
例如，在上述的实施方式中，通过控制部40来控制供水阀13的开闭或执行各运转，但也可以是其他结构。具体而言，可以通过用户对显示操作部10的操作来手动开闭供水阀13，也可以省略供水阀13本身，通过用户对水龙头(未图示)进行开闭来直接开始或停止供水。此外，也可以按照由设置于双桶式洗衣机1的机械计时器(未图示)指定的时间表来执行洗涤运转、脱水运转。
