Description

滚筒洗衣机 技术领域
本发明涉及一种滚筒洗衣机。该滚筒洗衣机既可以从洗涤连续进行至烘干，也可以进行洗涤而不进行烘干。
背景技术
以往，对于无法用洗衣机洗涤的精致的洗涤物，会将含有洗涤剂的水(以下称为“洗涤剂水”)蓄于盥洗盆、洗脸盆、洗脸池等来通过人手进行清洗即进行所谓的手洗。此外，对于受污严重的洗涤物，会在用洗衣机洗涤之前将洗涤剂水蓄于盥洗盆等中来通过人手进行清洗即进行所谓的预清洗。
此外，为了去除局部附着于洗涤物的污垢，有时会在清洗洗涤物整体之前进行清洗洗涤物的局部的所谓的局部清洗。专利文献1中记载了一种洗衣机，该洗衣机具备：水筒，设于箱体的顶面，能蓄水；以及超声波发生装置，产生超声波，通过该超声波来洗净浸泡于水筒内的水中的洗涤物的局部，该洗衣机能够进行洗涤物的局部清洗。
在专利文献1的洗衣机中，可以考虑不通过超声波进行洗涤物的局部清洗而使用蓄于水筒内的水通过人手来清洗洗涤物的方案。然而，在这种情况下，通过用手揉搓洗涤物，线屑等异物容易从洗涤物中放出，异物容易混入水筒内的水中。因此，希望在排水时异物不易与水筒内的水一起排出至机外。

发明内容
发明所要解决的问题
因此，本发明的目的在于提供一种滚筒洗衣机，其能通过手进行洗涤物的清洗，并且混入该清洗所使用的水中的异物不易被排出至机外。
用于解决问题的方案
本发明的主要方案的滚筒洗衣机具备：外筒，配置于箱体内；滚筒，以能旋转的方式配置于所述外筒内；洗净筒，设于所述箱体的顶面，蓄留用于清洗洗涤物的水；第一排水路，用于将所述外筒内的水向机外排出；排水过滤器，配置于所述第一排水路，捕集从所述外筒排出的水中所含的异物；以及第二排水路，从所述洗净筒内排出的水流过所述第二排水路。其中，所述第二排水路与所述第一排水路中的所述排水过滤器的上游或所述外筒的底部连接。
根据上述的结构，能在蓄有水的洗净筒内通过手进行洗涤物的清洗。而且，能在从洗净筒排水时通过配置于第一排水路的排水过滤器来捕集在通过手进行清洗时从洗涤物中放出并混入洗净筒内的水中的异物，因此能抑制异物向机外排出。
在本方案的滚筒洗衣机中，可以采用如下结构：所述第一排水路包括以能取出的方式收容所述排水过滤器的过滤器壳体。在该情况下，所述第二排水路可以与所述过滤器壳体的流入口连接。
根据上述的结构，能使含有异物的水从第二排水路直接流入排水过滤器，能通过排水过滤器来良好地捕集异物。
在本方案的滚筒洗衣机中，可以是，在比所述第二排水路靠上游处配置有辅助过滤器，所述辅助过滤器的异物捕集能力比所述排水过滤器的异物捕集能力低，所述辅助过滤器能经过所述洗净筒内进行拆装。
根据上述的结构，能通过辅助过滤器来进行异物的初级捕集，因此能减轻排水过滤器的负担。而且，由于辅助过滤器能经过洗净筒内进行拆装，因此能容易地丢弃由辅助过滤器捕集到的异物。
在本方案的滚筒洗衣机中，可以采用如下结构：还具备向所述洗净筒内和所述外筒内进行供水的供水装置。在该情况下，可以采用如下结构，即，所述供水装置包括：供水阀；供水路，与所述供水阀连接；第一分支水路，与所述 洗净筒相连；第二分支水路，与所述外筒相连；以及水路切换部，在所述供水路与所述第一分支水路连接的状态和所述供水路与所述第二分支水路连接的状态之间进行切换。
根据上述的结构，通过切换为供水路与第一分支水路连接的状态并使供水阀开放，能向洗净筒内供水，通过切换为供水路与第二分支水路连接的状态并使供水阀开放，能向外筒内供水。因此，能通过一个供水装置来向洗净筒和外筒进行供水。
在本方案的滚筒洗衣机中，可以采用如下结构，即，还具备：贮水筒，设于所述洗净筒的内部，能蓄水，其开口面积比所述洗净筒的开口面积小；以及超声波洗净部，位于所述贮水筒的上方，使超声波作用于浸泡在所述贮水筒内的水中的洗涤物的局部来洗净该局部。
根据上述的结构，能在蓄有水的贮水筒内通过超声波来进行洗涤物的局部清洗。并且，由于采用了设有开口面积比洗净筒的开口面积小的贮水筒并在通过超声波进行局部清洗时向贮水筒蓄水的结构，因此对于按洗涤物的待洗净的局部所浸泡的深度来蓄水而言，所需的水的使用量变少，能防止产生浪费水。此外，贮水筒位于洗净筒的内部，因此在通过超声波进行洗涤物的局部清洗时，水不易飞溅至机外。
在采用了上述的结构的情况下，可以采用如下结构：所述贮水筒形成于所述洗净筒的底面，并且所述滚筒洗衣机还具备：保持机构，将所述超声波洗净部保持为能在所述洗净筒的内部的所述贮水筒的上方的位置与所述洗净筒的外部的位置之间移动。
当采用这样的结构时，当在洗净筒内清洗洗涤物时，贮水筒不易造成妨碍。而且，当在洗净筒内清洗洗涤物时，能使超声波洗净部向洗净筒的外部退避，因此能防止超声波洗净部浸泡在蓄于洗净筒内的水中。此外，超声波洗净部不易妨碍洗净筒内进行的清洗。
发明效果
根据本发明，能提供一种滚筒洗衣机，该滚筒洗衣机能进行通过手的洗涤物的清洗，并且混入该清洗所使用的水中的异物不易被排出至机外。

一对第一连杆构件310和一对第二连杆构件320为大致L字形的中空构件。在一对第一连杆构件310和一对第二连杆构件320，分别在前侧的端部形成有圆筒状的前轴孔311、321并在后侧的端部形成有圆筒状的后轴孔312、322。
一对第一支承部330具有圆筒状的转动轴331，以在左右方向上转动轴331彼此对置的方式一体形成于箱体10的顶面。一对第二支承部340具有圆筒状的转动轴341，以在左右方向上转动轴341彼此背对的方式一体形成于箱体10的顶面。一对第二支承部340配置于比一对第一支承部330靠后方且内侧处。一对第一支承部330和一对第二支承部340形成为中空。
一对第二连杆构件320配置于一对第一连杆构件310的内侧。超声波洗净部200的第一转动轴223以能转动的方式插入于一对第一连杆构件310的前轴孔311中，一对第一支承部330的转动轴331以能转动的方式插入于一对第一连杆构件310的后轴孔312中。此外，超声波洗净部200的第二转动轴224以能转动的方式插入于一对第二连杆构件320的前轴孔321中，一对第二支承部340的转动轴341以能转动的方式插入于一对第二连杆构件320的后轴孔322中。
在箱体10的顶面设有与一方第一支承部330的内部连通的开口14。如图6所示，用于对超声波洗净部200的超声波振子211进行通电的布线C从箱体10内经由开口14、第一支承部330的内部以及第一连杆构件310的内部被引导至外壳220内。
当超声波洗净部200从位于图2所示的使用位置的状态被上提时，一对第一连杆构件310和一对第二连杆构件320向后方转动。由此，超声波洗净部200维持使用位置下的姿势向上方和后方移动，移动至如图3所示的退避位置。退避位置为箱体10的顶面中的洗净筒30的后方位置，在退避位置，超声波洗净 部200处于也不存在于洗净筒30的正上方区域的状态。
需要说明的是，超声波洗净部200的外壳220的前端部221在左右方向上具有尖头形状。因此，当超声波洗净部200移动至退避位置时，前端部221位于一对第二支承部340之间，不会与一对第二支承部340发生干涉。此外，当在超声波洗净部200位于使用位置的状态下关闭上盖20时，一对第一连杆构件310、一对第二连杆构件320、一对第一支承部330以及一对第二支承部340收容于上盖20的里侧的空间中。
＜洗净装置的动作＞
接下来，对洗净装置3的动作进行说明。
用户在进行洗涤物的局部清洗的情况下，在超声波洗净部200位于使用位置的状态下操作洗净按钮64。由此，在控制部70的控制下开始超声波洗净运转。
当超声波洗净运转开始时，通过供水装置100的第一供水部110，如下向贮水筒40内供给洗涤剂水。
首先，向贮留盒111内蓄留洗涤剂水。即，第一三通阀115a被切换为使第一供给管155与第一水路部113中的第一三通阀115a的下游侧连通的状态。此外，第二三通阀115b被切换为使第一水路部113中的第二三通阀115b的上游侧与下游侧连通的状态。而且，第三三通阀115c被切换为使第一水路部113中的第三三通阀115c的上游侧与下游侧连通的状态。而且，供给阀117被关闭。
供给泵112工作，第一水路部113内的空气被吸引而成为负压，第一药剂盒150内的液体洗涤剂经由第一供给管155被吸引至第一水路部113内。供给泵112工作规定时间，规定量的液体洗涤剂蓄于第一水路部113。
接下来，第一三通阀115a被切换为使第一水路部113中的第一三通阀115a的上游侧与下游侧连通的状态，第一供水阀114被打开。来自水龙头的纯水流向第一水路部113，冲走液体洗涤剂。纯水与液体洗涤剂混合而成为洗涤剂水。洗涤剂水经过供给泵112流入贮留盒111内。
当贮留盒111内蓄有规定量的洗涤剂水时，第一供水阀114被关闭。如此，贮留盒111中蓄有规定的洗涤剂浓度的洗涤剂水。
接下来，供给阀117被打开。贮留盒111内的洗涤剂水经过连接管118、第一导入口131以及罩部134从开口134a放出至合流部130内。洗涤剂水经过连接部140和供水口41流向贮水筒40，蓄于贮水筒40内。当如图2的单点划线所示贮水筒40内的水位上升至罩部134的开口134a的高度从而开口134a被洗涤剂水堵住时，贮留盒111内的气压与外部的气压相平衡。由此，保持供给阀117被打开的状态停止从贮留盒111供水。贮留盒111内留下满水时的三分之一左右的洗涤剂水。超声波发生体210的前端与水面接触。
当贮水筒40内蓄有洗涤剂水时，用户将洗涤物的污垢附着部分安置贮水筒40与超声波发生体210的振动变幅杆212之间。洗涤物的污垢附着部分浸泡于洗涤剂水中，浸透至洗涤物的内部的洗涤剂水渗出表面。呈现如下的状态：洗涤物的表面形成有薄薄的水层，振动变幅杆212与该水层接触。
当由于洗涤物吸水从而贮水筒40内的水量减少而水位下降使得罩部134的开口134a不再被洗涤剂水堵住时，从贮留盒111向贮水筒40内补给洗涤剂水，直至开口134a再次被洗涤剂水堵住。由此，贮水筒40内的水位即水量维持在适当的状态。
当供给阀117被打开后经过规定的等待时间时，对超声波振子211进行通电而使超声波发生体210工作。从振动变幅杆212的前端产生超声波，污垢通过超声波的作用而从洗涤物剥离。此时，由于洗涤剂的效力增大，洗净力提高。
当超声波发生体210开始工作后经过规定的运转时间时，超声波发生体210停止工作，超声波洗净运转结束。
用户将排水栓43从排水口42拆下，使排水口42开放。当排水口42被开放时，贮水筒40内的洗涤剂水流向第二排水路50。流过了第二排水路50的洗涤剂水流入过滤器壳体561内并穿过排水过滤器562。混入洗涤剂水中的线屑等异物由排水过滤器562捕集。然后，洗涤剂水流过第二排水软管552而向机外排出。
供给阀117被开放，贮留盒111中所剩余的洗涤剂水也经由贮水筒40等而向机外排出。
接下来，用户在进行洗涤物的手洗等的情况下，若超声波洗净部200处于 使用位置，则使其向退避位置移动，在超声波洗净部200位于退避位置的状态下操作洗涤剂水供给按钮65。由此，在控制部70的控制下，开始向洗净筒30内自动供水。
首先，与超声波洗净运转的情况同样地，通过供水装置100的第一供水部110来向贮水筒40内供给洗涤剂水。
接下来，通过供水装置100的第二供水部120来进行纯水的供给。即，三通阀123切换为使上游水路部122a与下游水路部122b连通的状态。第二供水阀121打开，来自水龙头的纯水流过第二水路部122并从第二导入口132放出至合流部130内。放出的纯水与洗涤剂水合流，进而经过连接部140和供水口41而流向贮水筒40，与洗涤剂水一起从贮水筒40溢出而蓄于洗净筒30内。纯水与洗涤剂水混合从而洗涤剂水被稀释，生成洗涤剂浓度比该洗涤剂水低的稀释洗涤剂水。在本实施方式中，通过纯水与洗涤剂水在合流部130合流，纯水与洗涤剂水容易混合。因此，蓄于洗净筒30内的稀释洗涤剂水的浓度容易变得均匀。
当洗净筒30内的水位上升并到达如图3的单点划线所示的规定水位L时，由水位检测装置80检测到该水位。由此，第二供水阀121被关闭，停止通过第二供水部120进行供水。规定水位L是比溢水口32的高度位置稍低的水位。此外，溢水口32的高度位置比合流部130的第二导入口132的高度位置低。
需要说明的是，罩部134、第一导入口131以及连接管118内充满洗涤剂水，罩部134的开口134a向下设置。因此，蓄于洗净筒30内的稀释洗涤剂水不会从位于比规定水位L低的位置的第一导入口131向第一供水部110中逆流。
如此，当洗净筒30内蓄有稀释洗涤剂水时，使用该稀释洗涤剂水在洗净筒30内进行洗涤物的手洗等。即，通过用户的手来清洗洗涤物。
用户在清洗完洗涤物时，将排水栓43从排水口42拆下，使排水口42开放。洗净筒30内的稀释洗涤剂水从排水口42排出并流过第二排水路50。流过第二排水路50的稀释洗涤剂水流入过滤器壳体561内，穿过排水过滤器562。混入稀释洗涤剂水中的线屑等异物由排水过滤器562捕集。然后，稀释洗涤剂水流过第二排水软管552而向机外排出。而且，贮留盒111中剩余的洗涤剂水也向 机外排出。
在此，当在洗净筒30内进行了手洗等时，由于洗涤物被用手进行了揉搓，因此与超声波洗净运转时相比，线屑等异物容易从洗涤物中放出。因此，混入稀释洗涤剂水中的异物也容易变多。然而，如此含在稀释洗涤剂水中的异物会由排水过滤器562充分捕集，因此会充分抑制异物向机外排出。
需要说明的是，当纯水从第二导入口132放出时，纯水有时会碰到罩部134等而向上方飞溅。在本实施方式中，采用了合流部130的空气从迷宫状的间隙排出的结构，该间隙通过将箱体10的顶面部的圆筒部13插入于合流部130的开口130a而产生，因此飞溅的水不易从合流部130漏出至外部。
而且，在供水因第二供水阀121、水位检测装置80的异常而不会停止，导致洗净筒30内的水位超过了溢水口32的高度位置的情况下，稀释洗涤剂水从溢水口32溢出，经过溢水软管54和第二排水路50被排出至机外。由此，防止稀释洗涤剂水从洗净筒30溢出或从第二导入口132逆流至第二水路部122。
接下来，用户在用纯水漂洗已清洗的洗涤物的情况下，操作供水按钮67。只通过第二供水部120进行纯水的供给，向洗净筒30内蓄留纯水至规定水位L。当漂洗结束时，从洗净筒30内进行排水。
需要说明的是，在通过第二供水部120进行供水之前，供给阀117关闭。由此，罩部134、第一导入口131以及连接管118内充满的空气无处可逃，因此蓄于洗净筒30内的纯水不会从罩部134的开口134a向第一供水部110中逆流。
接下来，在洗净筒30内使用药剂水进行洗涤物的处理的情况下，操作药剂水供给按钮66，上述情况包括向第二药剂盒160内先贮留液体柔顺剂并在用纯水漂洗之后用含有柔顺剂的水进行漂洗的情况、向第二药剂盒160内先贮留液体漂白剂并用含有漂白剂的水进行洗涤物的漂白的情况等。
通过与手洗的情况同样的供水装置100的动作，从第一供水部110供给含有药剂水即含有柔顺剂、漂白剂的水，然后从第二供水部120供给纯水，向洗净筒30内蓄留由纯水稀释后的药剂水至规定水位L。
不过，与手洗的情况不同的是，在第一供水部110中，为了向贮留盒111内进行药剂水的供给，第二三通阀115b被切换为使第二供给管165与第一水路 部113中的第二三通阀115b的下游侧连通的状态，并且第一三通阀115a被切换为使第一水路部113中的第一三通阀115a的上游侧与下游侧连通的状态。由此，当供给泵112工作时，第二药剂盒160的液体药剂即液体柔顺剂、液体漂白剂被吸引至第一水路部113。
当使用药剂水进行的洗涤物的处理结束时，从洗净筒30内进行排水。
＜洗衣机主体的动作＞
接下来，对洗衣机主体2的动作进行说明。
滚筒洗衣机1在洗衣机主体2中于控制部70的控制下进行各种运转模式的洗涤运转。在洗涤运转中，依次进行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。根据运转模式，有时会进行两次以上的漂洗过程和中间脱水过程。
在清洗过程中，向外筒520内蓄留含有洗涤剂的水至规定的清洗水位，该规定的清洗水位与收容于滚筒522内的洗涤物的负荷量相应，通过反复进行滚筒522的正转和反转，浸泡于该水中的洗涤物被翻滚。含有洗涤剂的水浸透至洗涤物的内部，通过洗涤剂的效力和由翻滚产生的机械力，附着于洗涤物的表面、内部的污垢被去除。
在漂洗过程中，在外筒520内蓄水至规定的漂洗水位的状态下，滚筒522进行正转和反转，洗涤物被翻滚。由此，洗涤物中所含的洗涤剂与水一起被排出，洗涤物被漂洗。
在中间脱水过程和最终脱水过程中，驱动马达530向一个方向高速旋转，滚筒522以作用于滚筒522内的洗涤物的离心力远大于重力的转速向一个方向旋转。通过离心力的作用，洗涤物被按压在滚筒522的内周面上而被脱水。在最终脱水过程中，滚筒522以比中间脱水过程中的转速高的转速旋转。
在进行清洗过程中的供水时，通过供水装置100向外筒520内进行供水并且自动投入液体洗涤剂。
即，在第一供水部110中，第一三通阀115a被切换为使第一供给管155与第一水路部113中的第一三通阀115a的下游侧连通的状态。此外，第二三通阀115b被切换为使第一水路部113中的第二三通阀115b的上游侧与下游侧连通的 状态。而且，第三三通阀115c被切换为使第一水路部113中的第三三通阀115c的上游侧与第一分支管116连通的状态。供给泵112工作规定时间，第一药剂盒150内的液体洗涤剂被吸引至第一水路部113内，规定量的液体洗涤剂蓄于第一水路部113。
接下来，第一三通阀115a被切换为使第一水路部113中的第一三通阀115a的上游侧与下游侧连通的状态，第一供水阀114被打开。来自水龙头的纯水流向第一水路部113，冲走液体洗涤剂。被冲走的液体洗涤剂经过第一分支管116流向注水口部526，从注水口部526向外筒520内投入。
在第二供水部120中，三通阀123被切换为使上游水路部122a与第二分支管124连通的状态。此外，在第一供水阀114被打开的同时，第二供水阀121被打开。来自水龙头的纯水经过第二水路部122的上游水路部122a和第二分支管124流向注水口部526，从注水口部526向外筒520内放出。
当外筒520内的水位到达规定的清洗水位时，第一供水阀114和第二供水阀121被关闭，供水结束。
在进行漂洗过程的供水时，通过供水装置100即第二供水部120，只进行纯水的供给，向外筒520内蓄留纯水至规定的漂洗水位。
在进行多次漂洗过程的情况且第二药剂盒160中贮留有液体柔顺剂的情况下，在最后的漂洗过程中，在供水时通过与清洗过程中的动作同样的供水装置100的动作，第二药剂盒160的液体柔顺剂被投入至外筒520内。
不过，与进行清洗过程中的供水时不同的是，在第一供水部110中，第二三通阀115b被切换为使第二供给管165与第一水路部113中的第二三通阀115b的下游侧连通的状态，并且第一三通阀115a被切换为使第一水路部113中的第一三通阀115a的上游侧与下游侧连通的状态。由此，当供给泵112工作时，第二药剂盒160的液体柔顺剂被吸引至第一水路部113。
在进行清洗过程、漂洗过程的排水时，从外筒520排出的水流过第一排水路550内而向机外排出。此时，排水中所含的线屑等异物由排水过滤器562捕集。由此，抑制异物向机外排出。
＜实施方式的效果＞
以上，根据本实施方式，能起到以下的效果。
滚筒洗衣机1具备：洗净筒30，设于箱体F的顶面，蓄留用于清洗洗涤物的水；第一排水路550，用于将外筒520内的水向机外排出；排水过滤器562，配置于第一排水路550，捕集从外筒520排出的水中所含的异物；以及第二排水路50，从洗净筒30内排出的水流过该第二排水路50，第二排水路50与第一排水路550中的排水过滤器562的上游连接。
根据该结构，能在蓄有水的洗净筒30内进行手洗、预洗、浸泡洗等通过手进行的洗涤物的清洗。而且，能在从洗净筒30排水时通过配置于第一排水路550的排水过滤器562来捕集在通过手进行的清洗时从洗涤物中放出并混入洗净筒30内的水中的线屑等异物，因此能抑制异物向机外排出。
在滚筒洗衣机1中，第一排水路550包括以能取出的方式收容排水过滤器562的过滤器壳体561，第二排水路50与过滤器壳体561的第二流入口561c连接。
根据该结构，能使含有异物的水从第二排水路50直接向排水过滤器562流入，能通过排水过滤器562来良好地捕集异物。
在滚筒洗衣机1中，在比第二排水路50靠上游处配置有作为辅助过滤器的排水过滤器44，该排水过滤器44的异物捕集能力比排水过滤器562的异物捕集能力低，该排水过滤器44能经过洗净筒30内进行拆装。
根据该结构，能通过排水过滤器44来进行异物的初级捕集，因此能减轻排水过滤器562的负担。而且，由于排水过滤器44能经过洗净筒30内进行拆装，因此能容易地丢弃由排水过滤器44捕集到的异物。
滚筒洗衣机1具备向洗净筒30内和外筒520内进行供水的供水装置100。供水装置100包括：第二供水阀121；上游水路部122a，与第二供水阀121连接；下游水路部122b，与洗净筒30相连；第二分支管124，与外筒520相连；以及三通阀123，在上游水路部122a与下游水路部122b连接的状态和上游水路部122a与第二分支管124连接的状态之间进行切换。
根据该结构，通过切换为上游水路部122a与下游水路部122b连接的状态并使第二供水阀121开放，能向洗净筒30内供水，通过切换为上游水路部122a 与第二分支管124连接的状态并使第二供水阀121开放，能向外筒520内供水。因此，能通过一个供水装置100来向洗净筒30和外筒520进行供水。
滚筒洗衣机1具备：贮水筒40，设于洗净筒30的内部，能蓄水，其开口面积比洗净筒30的开口面积小；以及超声波洗净部200，位于贮水筒40的上方，使超声波作用于浸泡在贮水筒40内的水中的洗涤物的局部来洗净该局部。
根据该结构，能在蓄有水的贮水筒40内通过超声波来进行洗涤物的局部清洗。并且，由于采用了设有开口面积比洗净筒30的开口面积小的贮水筒40并在通过超声波进行局部清洗时向该贮水筒40蓄水的结构，因此对于按洗涤物的待洗净的局部所浸泡的深度来蓄水而言，所需的水的使用量变少，能防止产生浪费水。此外，贮水筒40位于洗净筒30的内部，因此在通过超声波进行洗涤物的局部清洗时，水不易飞溅至滚筒洗衣机1外。
在滚筒洗衣机1中，贮水筒40形成于洗净筒30的底面。而且，该滚筒洗衣机1具备：保持机构300，将超声波洗净部200保持为能在洗净筒30的内部的贮水筒40的上方的位置与洗净筒30的外部的位置之间移动。
根据该结构，当在洗净筒30内清洗洗涤物时，贮水筒40不易造成妨碍。此外，在通过超声波进行洗涤物的局部清洗时，水极难飞溅至滚筒洗衣机1外。
而且，当在洗净筒30内进行洗涤物的手洗等时，能使超声波洗净部200向洗净筒30的外部的位置退避，因此能防止超声波洗净部200浸泡在蓄于洗净筒30内的水中。此外，超声波洗净部200不易妨碍手洗等。
以上，对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，此外，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＞
