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
在家庭内用洗衣机进行洗涤之前，有时会进行将部分附着于洗涤物的污垢去除的所谓局部清洗。专利文献1中记载了一种具备水筒和超声波发生装置并能进行洗涤物的局部清洗的洗衣机，该水筒设于箱体的顶面并能蓄水，超声波发生装置产生超声波并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。水筒内从供水装置被供水且从洗涤剂供给装置被供给洗涤剂。
在专利文献1的洗衣机中，超声波发生装置不固定于箱体，因此在洗净时，用户需要手持超声波发生装置，无法用双手好好地保持洗涤物。因此，会有如下的隐患：当用户在水筒内清洗洗涤物的受污部分时，由于从箱体的顶面露出的部分的重量，洗涤物容易从顶面滑落等，难以洗净洗涤物。

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，在通过超声波进行洗涤物的洗净的结构配备于箱体的顶面部的情况下，用户在通过超声波进行洗净时容易在顶面部处理洗涤物，能容易地洗净洗涤物。
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：箱状的箱体；外筒，配置于所述箱体内；以及横轴式滚筒，以能旋转的方式配置于所述外筒内。其中，在所述箱体的前表面部设有用于向所述滚筒内投入洗涤物的投入口。所述箱体的顶面部包括：第一面部，朝向后方向下倾斜；第二面部，位于所述第一面部的后方且比所述第一面部低的位置；第三面部，位于所述第二面部的后方且比所述第二面部高的位置；以及第四面部，从所述第二面部的后端立起，与所述第三面部的前端相连。在所述第二面部设有能蓄水的贮水筒，在所述贮水筒的上方配置有超声波洗净部，所述超声波洗净部固定于所述第四面部，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，由于超声波洗净部固定于第四面部，因此在通过超声波进行洗净时，用户能用双手保持洗涤物。此外，在洗净时，通过第一面部的斜面，洗涤物呈被推向后方的状态，因此即使用户不牢固地保持洗涤物，洗涤物也不易从顶面部向前方滑落。而且，当用户左右移动洗涤物来将受污部分带往贮水筒的位置时，第四面部引导洗涤物，因此容易稳定地左右移动洗涤物。因此，用户能容易地在顶面部通过超声波进行洗涤物的洗净。
在本方案的滚筒洗衣机中，可以采用所述超声波洗净部不突出至所述第三面部的上方的结构。而且，可以是，在所述箱体内，在形成于所述第三面部的正下方且所述第四面部的正后方的空间中，配置有向所述贮水筒内供给含有洗涤剂的水的洗涤剂水供给部。
根据上述的结构，超声波洗净部和洗涤剂水供给部为隔着第四面部沿着前后方向排列的配置结构，因此能抑制滚筒洗衣机的高度尺寸增加。而且，超声波洗净部不突出至第三面部的上方，而是收纳于第二面部的正上方的比第三面部低的空间中，因此能得到箱体的顶面部分的流畅的外观。此外，在将洗衣篮等物品载置于第三面部的情况下，超声波洗净部不易造成妨碍。
在采用了上述的结构的情况下，还可以采用如下结构：所述贮水筒向比所述第四面部靠后方处延伸。在该情况下，可以是，在所述空间内配置有供水构件，所述供水构件将来自所述洗涤剂水供给部的含有所述洗涤剂的水向所述贮水筒中的比所述第四面部靠后方的后侧部分放出。
若采用这样的结构，则放出至贮水筒内的含有洗涤剂的水不易飞溅至第二面部中的贮水筒的周边部分。此外，供水构件不出现在箱体外，因此使得箱体的顶面部分的外观更加流畅。
在本方案的滚筒洗衣机中，可以是，在所述第一面部和所述第二面部的左缘部和右缘部，沿着这些缘部设有从所述第一面部和所述第二面部立起的左壁部和右壁部。
根据上述的结构，贮水筒内的水即使漏出至第二面部，也能由左壁部和右壁部阻拦，因此能防止水向机外漏出。
在采用了上述的结构的情况下，可以采用如下结构，即，还具备：罩，以能开闭的方式从上方覆盖所述第一面部、所述第二面部、所述贮水筒以及所述超声波洗净部。在该情况下，可以采用所述左壁部和所述右壁部填充所述第一面部和所述第二面部与所述罩之间的间隙的结构。
若采用这样的结构，则能通过罩以及左壁部和右壁部来从上方向和左右方向保护贮水筒和超声波洗净部。此外，能通过左壁部和右壁部来支撑罩的左右两端部。

＜滚筒洗衣机的动作＞
滚筒洗衣机1中能进行各种运转模式的洗涤运转。洗涤运转在控制部615的控制下被执行。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20内蓄留含有洗涤剂的水至规定的清洗水位，通过反复进行滚筒22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20内蓄有达到规定的漂洗水位的水的状态下，滚筒22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同被排出，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30向一个方向高速旋转，滚筒22以使作用于滚筒22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22的内周面上而被脱水。在最终 脱水过程中，滚筒22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300，向外筒20内进行供水并且自动投入液体洗涤剂。
首先，在洗涤剂水供给部310中，第一三通阀313被切换为使第一供给管355与第一水路部312中的第一三通阀313的下游侧连通的状态。此外，第二三通阀314被切换为使第一水路部312中的第二三通阀314的上游侧与下游侧连通的状态。而且，第三三通阀315被切换为使第一水路部312中的第三三通阀315的上游侧与下游侧连通的状态。
供给泵316工作，第一水路部312内的空气被吸引而形成负压，洗涤剂盒350内的液体洗涤剂经由第一供给管355被吸引至第一水路部312内。供给泵316工作规定时间，规定量的液体洗涤剂蓄于第一水路部312。
接着，第一三通阀313被切换为使第一水路部312中的第一三通阀313的上游侧与下游侧连通的状态，第一供水阀311被打开。来自水龙头的水流向第一水路部312，将液体洗涤剂冲走。被冲走的液体洗涤剂流向注水口部26，并从注水口部26向外筒20内投入。
在供水部320中，在第一供水阀311被打开的同时，第二供水阀321被打开。来自水龙头的水经过第二水路部322流向注水口部26，从注水口部26向外筒20内放出。
当外筒20内的水位到达规定的清洗水位时，第一供水阀311和第二供水阀321被关闭，供水结束。需要说明的是，清洗水位被设定于比投入口13的下缘的位置高的位置。
在进行漂洗过程的供水时，只通过供水装置300进行供水部320的供水，向外筒20内蓄水至规定的漂洗水位。
在进行多次漂洗过程的情况下，在最后的漂洗过程中，通过在供水时进行与清洗过程中的动作同样的供水装置300的动作，柔顺剂盒360的液体柔顺剂被投入至外筒20内。
不过，与清洗过程中的供水时不同的是，在洗涤剂水供给部310中，第二三通阀314被切换为使第二供给管365与第一水路部312中的第二三通阀314 的下游侧连通的状态，并且第一三通阀313被切换为使第一水路部312中的第一三通阀313的上游侧与下游侧连通的状态。由此，当供给泵316进行工作时，柔顺剂盒360的液体柔顺剂被吸引至第一水路部312。
在进行清洗过程、漂洗过程的排水时，从外筒20排出的水流经第一排水路50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62捕集。由此，抑制异物向机外排出。
滚筒洗衣机1中能进行洗净运转。洗净运转在控制部615的控制下被执行。通过洗净运转，用户能在进行洗涤运转之前进行将局部附着于洗涤物的污垢去除的所谓局部清洗。
当用户操作洗净按钮611e时，洗净运转开始。
当洗净运转开始时，通过供水装置300的洗涤剂水供给部310，洗涤剂水如下所述地被供给至贮水筒110内。
首先，向贮留盒317内蓄留洗涤剂水。即，第一三通阀313被切换为使第一供给管355与第一水路部312中的第一三通阀313的下游侧连通的状态。此外，第二三通阀314被切换为使第一水路部312中的第二三通阀314的上游侧与下游侧连通的状态。而且，第三三通阀315被切换为使第一水路部312中的第三三通阀315的上游侧与贮留盒317的流入口连通的状态。而且，供给阀318被关闭。供给泵316工作规定时间，规定量的液体洗涤剂蓄于第一水路部312。
接着，第一三通阀313被切换为使第一水路部312中的第一三通阀313的上游侧与下游侧连通的状态，第一供水阀311被打开。来自水龙头的水流向第一水路部312，将液体洗涤剂冲走。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316和第三三通阀315流入至贮留盒317内。
当贮留盒317内蓄有规定量的洗涤剂水时，第一供水阀311被关闭。如此，在贮留盒317中蓄有规定的洗涤剂浓度的洗涤剂水。
接着，供给阀318被打开。贮留盒317内的洗涤剂水经过供给喷嘴400而从放出口401放出至贮水筒110的后侧部分112，蓄于贮水筒110内。此时，后侧部分112存在于第四面部104的后方即箱体10的内部，因此放出的洗涤剂水不易飞溅至第二面部102中的贮水筒110的周围。此外，后侧部分112的正上 方的空间S2a通过左右的侧面壁106和后表面壁107而与周围的空间S2b隔断，因此放出的洗涤剂水不易飞溅至空间S2b即箱体10内的空间S2a的外部。
当如图1的单点划线所示贮水筒110内的水位上升至放出口401的高度从而放出口401被洗涤剂水堵住时，贮留盒317内的气压与外部的气压相平衡。由此，保持供给阀318被打开的状态停止从贮留盒317供水。贮留盒317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110内蓄有洗涤剂水时，用户将洗涤物载置于第一面部101和第二面部102，将洗涤物的污垢附着部分放置于贮水筒110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。呈现出在洗涤物的表面形成有薄的水层且振动变幅杆212与该水层接触的状态。
此时，用户以使洗涤物在第一面部101的斜面上滑动的方式向前方移动洗涤物，由此能将污垢附着部分顺畅地带往贮水筒110的位置。此外，洗涤物碰到第四面部104时会被阻挡，因此洗涤物不会过于前往后方。
当由于洗涤物吸收贮水筒110内的洗涤剂水从而贮水筒110内的水量减少而水位下降使得放出口401不再被洗涤剂水堵住时，从贮留盒317向贮水筒110内补给洗涤剂水直至放出口401再次被洗涤剂水堵住。由此，贮水筒110内的水位即水量维持在适当的状态。
当供给阀318被打开之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，通过超声波的作用，污垢从洗涤物剥离。此时，通过洗涤剂效力增大，洗净力提高。
用户一边左右移动洗涤物，一边使受污部分触碰振动变幅杆212来将该部分的污垢去除。此时，第四面部104引导洗涤物，因此用户容易稳定地左右移动洗涤物。此外，通过第一面部101的斜面，洗涤物呈被推向后方的状态，因此即使用户不牢固地保持洗涤物，洗涤物也不易从箱体10的顶面部10b向前方滑落。而且，贮水筒110内的洗涤剂水即使被洗涤物挤压等而溢出至第二面部102并扩散，也会被倾斜的第一面部101以及左壁部105L和右壁部105R阻拦，不易向箱体10外漏出。
当超声波发生体210开始动作之后经过规定的运转时间时，超声波发生体210停止工作，洗净运转结束。
第二排水阀510被开放，贮水筒110内的洗涤剂水经过排水口113流向第二排水路520。流过了第二排水路520的洗涤剂水流入外筒20内。此时，第一排水阀40被开放，洗涤剂水流经第一排水路50排出至机外。混入洗涤剂水中的线屑等异物由排水过滤器62捕集。
供给阀318被开放，贮留盒317中所剩余的洗涤剂水也经由贮水筒110等向机外排出。
在本实施方式的滚筒洗衣机1中，能同时进行洗涤运转和洗净运转。即，在洗涤运转中也能开始洗净运转，在洗净运转中也能开始洗涤运转。
在滚筒洗衣机1中，在脱水时箱体10容易上下大幅摇晃。因此，当在洗涤运转的脱水过程中即中间脱水过程中或最终脱水过程中进行了洗净运转时，贮水筒110内的洗涤剂水容易飞溅至机外。因此，在本实施方式中，通过控制部615，执行以下所示的用于使洗净运转与脱水过程不重合的控制处理。由此，能防止在洗净运转中贮水筒110内的洗涤剂水由于箱体10的摇晃而飞溅至机外。
图5的(a)是表示在开始洗净运转时进行的用于使洗净运转与脱水过程不重合的控制处理的流程图。
参照图5的(a)，当通过洗净按钮611e进行了洗净运转的开始操作时(S101：是)，控制部615判定是否处于脱水过程中(S102)。若不处于脱水过程中(S102：否)，则控制部615开始洗净运转(S103)。另一方面，若处于脱水过程中(S102：是)，则控制部615使开始操作无效(S104)，不开始洗净运转。
需要说明的是，控制部615也可以设为在脱水过程结束时自动开始洗净运转。
图5的(b)是表示在洗涤运转中进行的用于使洗净运转与洗涤运转的脱水过程不重合的控制处理的流程图。
参照图5的(b)，当脱水过程之前的过程即清洗过程或漂洗过程结束时(S201：是)，控制部615判定是否处于洗净运转中(S202)。若不处于洗净运转中(S202：否)，则控制部615开始脱水过程(S203)。另一方面，若处 于洗净运转中(S202：是)，则控制部615等待直至洗净运转结束(S204：否)。然后，当洗净运转结束时(S204：是)，控制部615开始脱水过程(S203)。
而且，在洗涤运转的清洗过程中，会蓄水至比投入口13的下缘高的清洗水位，因此为了使门14不会被打开，会通过锁门装置628进行门14的锁定。因此，在供水的中途无法进行洗涤物向滚筒22内的追加投入。在开始洗涤运转时正在进行洗净运转的情况下，设为通过该洗净运转已被洗净的洗涤物容易在门14无法打开之前追加投入至滚筒22内为好。因此，在本实施方式中，通过控制部615，在清洗过程的供水时执行以下所示的控制处理。
图6是表示在清洗过程的供水时执行的控制处理的流程图。
参照图6，当清洗过程中的供水开始时，控制部615基于水位传感器614的检测结果，监测外筒20内的水位是否已到达锁门水位(S301)。锁门水位被设定为比投入口13的下缘低的规定水位。
当外筒20内的水位到达锁门水位时(S301：是)，控制部615判定是否正在进行洗净运转(S302)。正在进行洗净运转的情况下(S302：是)，控制部615关闭第一供水阀311和第二供水阀321，停止向外筒20内供水(S303)。然后，控制部615通过显示部612中的显示和/或来自声音输出部613的声音，进行督促用户追加洗涤物的通知(S304)。然后，控制部615等待通过开始按钮611c进行恢复操作(S305)。
用户在追加通过洗净运转清洗完成的洗涤物之后，或者在不追加该洗涤物的情况下，进行恢复操作。当完成恢复操作时(S305：是)，控制部615打开第一供水阀311和第二供水阀321来恢复向外筒20内供水(S306)，并且使锁门装置628工作来进行门14的锁定(S307)。
需要说明的是，在外筒20内的水位到达锁门水位时尚未进行洗净运转的情况下(S302：否)，控制部615不停止供水地进行门14的锁定(S307)。
＜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的箱体10的顶面部10b包括：第一面部101，朝向后方向下倾斜；第二面部102，位于第一面部101的后方且比第一面部101低的位置；第 三面部103，位于第二面部102的后方且比第二面部102高的位置；以及第四面部104，从第二面部102的后端立起，与第三面部103的前端相连。在第二面部102设有蓄留洗涤剂水的贮水筒110，在贮水筒110的上方配置有超声波洗净部200，该超声波洗净部200固定于第四面部104，使超声波作用于浸泡在贮水筒110内的洗涤剂水中的洗涤物的局部来洗净该局部。
根据该结构，由于超声波洗净部200固定于第四面部104，因此在通过超声波进行洗净时，用户能用双手保持洗涤物。此外，在洗净时，通过第一面部101的斜面，洗涤物呈被推向后方的状态，因此即使用户不牢固地保持洗涤物，洗涤物也不易从顶面部10b向前方滑落。而且，当用户左右移动洗涤物来将受污部分带往贮水筒110的位置时，第四面部104引导洗涤物，因此容易稳定地左右移动洗涤物。因此，用户能容易地在顶面部10b通过超声波进行洗涤物的洗净。
滚筒洗衣机1中，超声波洗净部200不突出至第三面部103的上方，在箱体10内的形成于第三面部103的正下方且第四面部104的正后方的空间S2中，配置有向贮水筒110内供给洗涤剂水的洗涤剂水供给部310。
根据该结构，超声波洗净部200和洗涤剂水供给部310为隔着第四面部104在前后方向上排列的配置结构，因此能抑制滚筒洗衣机1的高度尺寸增加。需要说明的是，在采用了超声波洗净部200和洗涤剂水供给部310沿着上下方向即箱体10的高度方向排列的结构的情况下，滚筒洗衣机1的高度尺寸容易大幅增加。
而且，超声波洗净部200不突出至第三面部103的上方，而是收纳于第二面部102的正上方的比第三面部103低的空间S1中，因此能得到箱体10的顶面部分的流畅的外观。此外，在将洗衣篮等物品载置于第三面部103的情况下，超声波洗净部200不易造成妨碍。
在滚筒洗衣机1中，在第一面部101和第二面部102的左缘部及右缘部，沿着这些缘部设有从第一面部101和第二面部102立起的左壁部105L和右壁部105R。
根据该结构，贮水筒110内的洗涤剂水即使漏出至第二面部102，也能由左 壁部105L和右壁部105R阻拦，因此能防止洗涤剂水向机外漏出。
在滚筒洗衣机1中，贮水筒110向比第四面部104靠后方处延伸，在空间S2内配置有供给喷嘴400，该供给喷嘴400将来自洗涤剂水供给部310的洗涤剂水向贮水筒110中的比第四面部104靠后方的后侧部分112放出。
根据该结构，放出至贮水筒110内的洗涤剂水不易飞溅至第二面部102中的贮水筒110的周边部分。此外，供给喷嘴400不会出现在箱体10外，因此使得箱体10的顶面部分的外观流畅。
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＞
图7的(a)是变更例1的滚筒洗衣机1的上部的侧面剖视图。图7的(b)是变更例1的滚筒洗衣机1的俯视图。
本变更例的滚筒洗衣机1具备罩700，该罩700以能开闭的方式从上方覆盖第一面部101、第二面部102、贮水筒110以及超声波洗净部200。
罩700具有后表面和底面开放的方形的箱状。罩700的前后和左右的尺寸与顶面部10b中的比第四面部104靠前侧部分处的前后和左右的尺寸相等。此外，罩700的上下尺寸等于第一面部101的上端和第三面部103的表面之间的距离。
左壁部105L和右壁部105R的上端与第一面部101的上端为相同高度且呈水平，左壁部105L和右壁部105R的上端分别与罩700的左侧面部和右侧面部的下端相接。第一面部101和第二面部102与罩700之间的间隙被左壁部105L和右壁部105R填充。
罩700被设为能通过拆装来进行开闭，在使用贮水筒110和超声波洗净部200时被打开。需要说明的是，也可以设为：在罩700的后端部与第三面部103的前端部之间设有铰链部，罩700以铰链部为支点进行开闭。
根据本变更例，能通过罩700以及左壁部105L和右壁部105R来从上方向和左右方向保护贮水筒110和超声波洗净部200。此外，能通过左壁部105L和 右壁部105R来支撑罩700的左右两端部。
而且，罩700的顶面与第三面部103的表面平齐，因此包括罩700的顶面在内的箱体10的顶面整体处于平坦的状态，容易在箱体10上载置洗衣篮等物品。
＜其他变更例＞
第一面部101的结构不限于上述实施方式的结构。例如，也可以是，第一面部101的倾斜角度在中途发生变化。例如，既也可以设为：如图8的(a)所示，第一面部101的前侧部分101a的倾斜角度大于后侧部分101b的倾斜角度，也可以设为：如图8的(b)所示，第一面部101的后侧部分101b的倾斜角度大于前侧部分101a的倾斜角度。此外，例如，第一面部101既可以凹弯曲也可以凸弯曲。
而且，在上述实施方式中，第一面部101的后端与第二面部102的前端相连。然而，也可以是，如图8的(c)所示，在第一面部101与第二面部102之间设有台阶。
而且，左壁部105L和右壁部105R的结构不限于上述实施方式的结构。例如，也可以是，左壁部105L和右壁部105R不被设为比第一面部101的上端高的壁部，而是如图8的(d)所示被设为从第一面部101和第二面部102以大致相等的高度立起的、比第一面部101的上端低的壁部。在该情况下，在左右移动较大的洗涤物时，左壁部105L和右壁部105R不易造成妨碍。而且，也可以采用设置左壁部105L和右壁部105R直至第一面部101的中途部分的结构。
而且，也可以是，在第一面部101和第二面部102不设左壁部105L和右壁部105R。
而且，洗涤剂水供给部310的结构不限于上述实施方式的结构，只要能向贮水筒110内供给洗涤剂水，可以为任何结构。例如，洗涤剂水供给部310也可以采用不设贮留盒317而从第一水路部312直接向贮水筒110内供给洗涤剂水的结构。此外，洗涤剂水供给部310也可以采用如下结构：不在第一水路部312中混合水和洗涤剂，使从洗涤剂盒350直接投入至贮留盒317内的洗涤剂与从第一水路部312供给至贮留盒317内的水在贮留盒317内混合。
而且，在上述实施方式中，洗涤剂水供给部310具有向外筒20内自动投入洗涤剂和柔顺剂的功能。然而，洗涤剂水供给部310也可以不具有这样的功能。在该情况下，在洗涤剂水供给部310不设柔顺剂盒360、第二供给管365以及第二三通阀314。而且，洗涤剂水供给部310也可以具有向外筒20内只自动投入洗涤剂的功能。
而且，在上述实施方式中，采用了贮水筒110向比第四面部104靠后方处延伸并进入箱体10内的结构。然而，也可以采用贮水筒110仅设于第二面部102而不进入箱体10内的结构。在该情况下，也可以是，洗涤剂水从露出于箱体10的外部的供给喷嘴400向贮水筒110内放出。而且，也可以采用贮水筒110的前端部延伸至第一面部101的后部的结构。
而且，在上位实施方式中，洗涤剂水通过供给喷嘴400向贮水筒110内放出。然而，也可以设为：洗涤剂水通过具有供给喷嘴400以外的形态的供水构件向贮水筒110内放出。
而且，在上述实施方式中，在图5的(a)的控制处理中，设为在处于脱水过程中的情况下不开始洗净运转。然而，虽然不如脱水过程的程度，但即使在清洗过程和漂洗过程中，箱体10也容易上下摇晃。因此，图5的(a)的控制处理也可以变更为：不仅在脱水过程中不开始洗净运转，在清洗过程和漂洗过程中也不开始洗净运转。同样地，图5的(b)的控制处理也可以变更为：在清洗过程或漂洗过程开始时正在进行洗净运转的情况下，等到洗净运转结束再开始清洗过程或漂洗过程。
而且，在上述实施方式中，在箱体10内的形成于第三面部103的正下方且第四面部104的正后方的空间S2中，配置有洗涤剂水供给部310和供水部320双方。然而，只要在空间S2内至少配置有洗涤剂水供给部310即可，供水部320也可以配置于箱体10内的空间S2以外的场所。
而且，超声波洗净部200的结构不限于上述实施方式的结构，只要能使超声波作用于浸泡在贮水筒110内的水中的洗涤物的部分，可以为任何结构。
而且，在上述实施方式中，通过使第一面部101的局部凹陷而形成了贮水筒110。然而，也可以通过用肋等壁部包围第一面部101的局部来形成贮水筒 110。
而且，上述实施方式的滚筒洗衣机1不具备烘干功能，但本发明也可以应用于具备烘干功能的滚筒洗衣机即滚筒式洗干一体机。
另外，本发明的实施方式可以在技术方案所示的技术思想的范围内适当进行各种变更。
