如图2的(a)所示，在进行洗净运转时，超声波洗净装置50从收纳部17被拉出而向上面板12的投入口14的内侧突出。另一方面，如图2的(b)和(c)所示，在不进行洗净运转时，超声波洗净装置50收纳于收纳部17。收纳部17的出入口18被罩19关闭。此时，罩19的下端抵接于贮水部200的前端部。
在上面板12的内部设有自动出入装置90。自动出入装置90在洗净运转开始时将收纳于收纳部17内的超声波洗净装置50拉出至投入口14内。而且，自动出入装置90在洗净运转结束时将被拉出至投入口14内的超声波洗净装置50收纳于收纳部17内。
而且，自动出入装置90与超声波洗净装置50向收纳部17的出入动作联动地对罩19进行开闭。当超声波洗净装置50收纳于收纳部17时，罩19从收纳于收纳部17的收纳位置向关闭出入口18的封闭位置移动。即，罩19关闭。当超声波洗净装置50从收纳部17拉出时，罩19从封闭位置向收纳位置移动。即，罩19打开。需要说明的是，收纳部17被分为收纳超声波洗净装置50的装置收纳部17a和邻接于装置收纳部17a的上方并收纳敞开的罩19的罩收纳部17b。
图3是贮水部200从基体部300脱离的状态的超声波洗净装置50的立体图。图4是超声波洗净部100的前部的侧剖图。需要说明的是，图3中示出了排水口211打开的状态的贮水部200。
超声波洗净装置50中，超声波洗净部100保持于基体部300，贮水部200以能脱离的方式装接于基体部300。
超声波洗净部100具备超声波发生体110和外壳120。超声波发生体110包括超声波振子111和与超声波振子111结合的振动变幅杆112。超声波发生体110通过超声波振子111的高频振动来从振动变幅杆112的前端产生超声波。
外壳120具有在前后方向上延伸且其前端部121向下方弯曲的臂形。在外壳120内的前部配置有超声波发生体110。振动变幅杆112的前端部从外壳120的开口部122露出。
外壳120的后部123固定于基体部300的上部。在外壳120的后部设有向 上方突出的方形板状的被检测部124。
在贮水部200形成有具有沿循贮水部200的形状的形状的贮水桶210。在贮水桶210，于后表面的下部形成有排水口211。排水口211被阀体220闭塞。在阀体220连结有阀可动构件230。阀可动构件230的后部231比贮水部200向后方突出。阀可动构件230被未图示的弹簧向阀体220关闭的后方向施力。
当超声波洗净装置50从收纳部17拉出时，通过阀体220，排水口211成为封闭的状态。当超声波洗净装置50收纳于收纳部17时，阀可动构件230抵接于排水承接部70的后壁并向前方移动。由此，如图3所示，阀体220向前方移动，排水口211打开。当排水口211打开时，贮水桶210内的洗净水向排水承接部70排出。阀体220和阀可动构件230包括在根据超声波洗净装置50向收纳部17的出入动作来使排水口211自动开闭的自动开闭机构中。
接着，对罩19和自动出入装置90进行详细说明。

参照图5的(a)至图7的(b)，两个连杆机构410具有左右颠倒的形状。在上面板12的内部，超声波洗净装置50被连杆保持构件420从左右方向和下方向覆盖，被罩引导构件430从上方向覆盖。由连杆保持构件420和罩引导构件430包围出的空间成为装置收纳部17a，罩引导构件430的上方成为罩收纳部17b。连杆保持构件420相当于本发明的“保持部”。
各连杆机构410包括：第一滑动件440、第二滑动件450以及连杆460。
第一滑动件440具有大致长圆板状，固定于超声波洗净装置50的基体部300的侧面下部。在第一滑动件440，在其与基体部300之间设有沿前后方向排列的两个圆筒状的滑动部441。此外，在第一滑动件440的前侧设有向外侧突出的轴部442。
第二滑动件450具有大致长圆板状。在第二滑动件450以沿前后方向排列的方式设有向内侧突出的两个圆筒状的滑动部451。圆筒状的突起部452从后侧的滑动部451向内侧突出。此外，在第二滑动件450，于两个滑动部451之间设有具有截面倒U字的方形板的安装部453。在安装部453形成有安装孔453a。而且，在第二滑动件450，于后端部设有向外侧突出的轴部454，于前端部形成有凸台孔455。而且，在右侧的第二滑动件450设有向外侧延伸的卡合片456。
连杆460具有细长板状。在连杆460形成有一端侧细长的长圆状的连结孔461。连结孔461中以可滑动的方式嵌入有第一滑动件440的轴部442。由此，连杆460的一端侧连结于第一滑动件440。此外，在连杆460的另一端部设有连结凸台462。连结凸台462中可旋转的方式嵌入有第二滑动件450的轴部454。由此，连杆460的另一端侧与第二滑动件450连结。而且，在连杆460的另一端侧形成有长圆形的固定孔463。
连杆保持构件420保持左右两个连杆机构410。连杆保持构件420由金属制的基座构件471以及树脂制的左侧面构件472和右侧面构件473构成。左侧面 构件472和右侧面构件473具有左右颠倒的形状。
基座构件471包括底面部471a以及从底面部471a的左右两端立起的左侧面部471b和右侧面部471c。在左侧面部471b和右侧面部471c的外侧分别安装有左侧面构件472和右侧面构件473。由左侧面部471b和左侧面构件472构成连杆保持构件420的左侧面部420a。由右侧面部471c和右侧面构件473构成连杆保持构件420的右侧面部420b。
需要说明的是，在基座构件471，于后侧装接有排水承接部70。排水承接部70的前部重叠在基座构件471的底面部471a之上。
在连杆保持构件420的左侧面部420a和右侧面部420b，于下部和上部分别形成有第一滑动孔421和第二滑动孔422。第一滑动孔421和第二滑动孔422具有细长的长圆形，在前后方向即超声波洗净装置50出入于装置收纳部17a的方向上延伸。
第一滑动孔421中插入有第一滑动件440的滑动部441。通过使滑动部441在第一滑动孔421中滑动，第一滑动件440被第一滑动孔421引导而能沿前后方向滑动。第二滑动孔422中插入有第二滑动件450的滑动部451。通过使滑动部451在第二滑动孔422中滑动，第二滑动件450被第二滑动孔422引导而能沿前后方向滑动。像这样，第一滑动件440和第二滑动件450通过连杆保持构件420被保持为能向前后方向即拉出方向和后方向即收纳方向滑动。
在左侧面部420a和右侧面部420b，于上部的中央部形成有圆筒状的固定轴423。固定轴423插入连杆460的固定孔463中。连杆460能以固定轴423为中心在前后方向上转动，当连杆460的一端侧向前方或后方移动时，连杆460另一端侧与一端侧相反地向后方或前方移动。
在固定轴423的前端安装有外径比固定孔463大的垫圈480。固定孔463的周缘部分被垫圈480固定，由此连杆460不会从固定轴423向外侧脱落。
在左侧面部420a和右侧面部420b，于上部的前端部和后端部形成有安装凸台424，在后端部的安装凸台424附近形成有安装孔425。两个安装凸台424和安装孔425在将罩引导构件430安装于连杆保持构件420时被使用。各安装凸台424为中空，在左侧面部420a和右侧面部420b的内侧具有开口424a。
罩引导构件430包括顶面部430a和从顶面部430a的左右两端垂下的左侧面部430b和右侧面部430c。
从上方观察时，顶面部430a具有大致方形。在顶面部430a，于左右的端部形成有从前端向后方延伸的平坦的导轨面431。此外，在顶面部430a，于导轨面431的后方以朝向外侧的方式形成有安装凸台432。
在顶面部430a，于中央部以沿前后方向延伸的方式形成有齿条引导槽433。在齿条引导槽433的后部形成有堵住槽的上方的方形的罩部433a。此外，在顶面部430a，于齿条引导槽433的后部的左侧和右侧分别设有马达装接部434和小齿轮支承部435。马达装接部434包括与小齿轮支承部435对置的马达支承部434a。小齿轮支承部435具有向马达支承部434a侧突出的支轴435a。
在顶面部430a，于比后端部的中央稍靠右侧处设有第一开关装接部436，于比右端部的中央稍靠后侧处设有第二开关装接部437。在第一开关装接部436形成有向上方突出的一对爪部436a和一对销436b。在第二开关装接部437形成有向右方突出的一对爪部437a和一对销437b。
在左侧面部430b和右侧面部430c，于前端部和后端部形成有嵌合凸台438。
罩引导构件430安装于连杆保持构件420的上端部。此时，罩引导构件430的左侧面部430b的两个嵌合凸台438从内侧嵌入于连杆保持构件420的左侧面部420a的两个安装凸台424的内部，罩引导构件430的右侧面部430c的两个嵌合凸台438从内侧嵌入于连杆保持构件420的右侧面部420b的两个安装凸台424的内部。
此外，罩引导构件430的左侧面部430b的安装凸台432与连杆保持构件420的左侧面部420a的安装孔425匹配，罩引导构件430的右侧面部430c的安装凸台432与连杆保持构件420的右侧面部420b的安装孔425匹配。在左右两侧，安装凸台424和嵌合凸台438被未图示的螺钉固定，安装凸台432被未图示的螺钉固定于安装孔425。
参照图5的(a)、(b)和图8的(a)、(b)，在罩引导构件430的马达装接部434装接有马达91。马达91的前端部支承于马达支承部434a。如图5的(a)所示，马达91被马达罩93从上方覆盖。
齿条小齿轮机构500包括小齿轮510、齿条520以及连结构件530，将马达91的旋转运动转换为直线运动并传递至连杆机构410。具体而言，齿条小齿轮机构500随着马达91的旋转而使第二滑动件450沿前后方向滑动。齿条小齿轮机构500相当于本发明的传递机构。
小齿轮510安装于马达91的旋转轴91a。小齿轮支承部435的支轴435a插入形成于小齿轮510的前端面的轴孔511中。由此，小齿轮510的前端侧被支轴435a支承为旋转自如。齿条520在前后方向上为长尺寸，收容于齿条引导槽433并与小齿轮510啮合。罩部433a从上方覆盖齿条520的后侧。
连结构件530在左右方向上为长尺寸，包括树脂制的主体构件531和金属制的加强构件532。齿条520以从主体构件531的中央部向后方延伸的方式与主体构件531一体地形成。
在主体构件531，于左右的端部设有长方体状的安装凸台533和向外侧开口的圆形的插入孔534。在安装凸台533形成有安装孔533a。在主体构件531，于右侧的端部的内侧设有被检测部535。被检测部535具有后端部隆起的长方形的板状。
加强构件532以覆盖主体构件531的前表面和上表面的方式通过三根螺钉536固定于主体构件531。主体构件531被加强构件532加强，由此连结构件530的刚性提高。
连结构件530的左右的端部安装于左右的第二滑动件450。此时，连结构件530的左右的安装凸台533从下方嵌入左右的第二滑动件450的安装部453并由未图示的螺钉固定。左右的第二滑动件450的突起部452插入连结构件530的左右的插入孔534中。
在自动出入装置90设有：收纳检测开关710，检测超声波洗净装置50被收纳于收纳部17内的情况；以及拉出检测开关720，检测超声波洗净装置50被拉出至投入口14内的情况。收纳检测开关710和拉出检测开关720例如是微型开关。收纳检测开关710相当于本发明的收纳检测部，拉出检测开关720相当于本发明的拉出检测部。
如图8的(a)所示，收纳检测开关710装接于第一开关装接部436并由一 对爪部436a和一对销436b固定。此外，拉出检测开关720装接于第二开关装接部437并由一对爪部437a和一对销437b固定。
图9的(a)是用于对收纳检测开关710进行说明的图，图9的(b)是用于对拉出检测开关720进行说明的图。
如图9的(a)所示，收纳检测开关710具有：按钮712，从开关主体部711向外侧突出；以及杆713，与按钮712接触。收纳检测开关710以按钮712和杆713位于开关主体部711的左侧的方式装接于第一开关装接部436。当超声波洗净装置50收纳于收纳部17内时，移动至后方的超声波洗净部100的被检测部124与杆713接触，按钮712被压入开关主体部711内。由此，收纳检测开关710接通，输出接通信号。
如图9的(b)所示，拉出检测开关720具有：按钮722，从开关主体部721向外侧突出；以及杆723，与按钮722接触。拉出检测开关720以按钮712和杆713位于开关主体部721的下侧的方式装接于第二开关装接部437。当超声波洗净装置50拉出至投入口14内时，移动至后方的连结构件530的被检测部535与杆723接触，按钮722被压入开关主体部721内。由此，拉出检测开关720接通，输出接通信号。
参照图5的(a)、(b)和图6，罩19由具有透光性的树脂材料形成。罩19包括覆盖出入口18的大致方形板状的主体部610和设于主体部610的左右的两端并向后方延伸的侧面部620。侧面部620的后缘在其上部具有向前方凹陷的凹部621，在该凹部621的下方具有呈直线状延伸的直线部622。
在各侧面部620的上端部设有向外侧突出的转动轴630。转动轴630能转动地嵌入第二滑动件450的凸台孔455中。由此，罩19的上端部以能在上下方向即开闭出入口18的方向上转动的方式连结于第二滑动件450。在罩19的右侧的转动轴630安装有扭簧640。
扭簧640的一端与安装于转动轴630的卡合体650卡合，另一端与第二滑动件450的卡合片456卡合。扭簧640向封闭出入口18的方向对罩19施力。
接着，对超声波洗净装置50从收纳部17出入的动作和罩19随着该动作而开闭的动作进行说明。
图10的(a)是表示罩19打开的情形的图。图10的(b)是用于对装置保持部428的结构进行说明的图。方便起见，在图10的(a)中用虚线表示超声波洗净部100的前端部。
如图5的(a)所示，在超声波洗净装置50收纳于收纳部17即装置收纳部17a时，第一滑动件440位于第一滑动孔421的后端部。连杆460的与第一滑动件440连结的一端侧位于后方，另一端侧位于前方，与另一端侧连结的第二滑动件450位于第二滑动孔422的前端部。齿条小齿轮机构500中，与第二滑动件450连结的连结构件530位于最靠前的位置，齿条520位于最靠前的位置。
当收纳于装置收纳部17a内的超声波洗净装置50被拉出至投入口14内时，马达91向第一方向即从右侧观察超声波洗净装置50时的逆时针方向旋转，小齿轮510向相同方向旋转。当小齿轮510向第一方向旋转时，齿条520向用于将超声波洗净装置50向投入口14内拉出的方向即后方向移动。由此，连结构件530和第二滑动件450向后方向移动。连杆460转动，其另一端侧向后方向移动，其一端侧向前方向移动。第一滑动件440向前方向滑动，如图5的(b)所示，超声波洗净装置50从装置收纳部17a被拉出。超声波洗净装置50向投入口14的内侧伸出。
如图10的(a)所示，当第二滑动件450开始向后方向滑动时，罩19的侧面部620的凹部621抵接于罩引导构件430的前端部。然后，随着第二滑动件450向后方向滑动，凹部621维持抵接于罩引导构件430的前端部的状态，且罩19打开而被收纳向罩收纳部17b。当罩19打开至大致水平的状态时，罩19的侧面部620的直线部622爬上导轨面431，然后沿导轨面431向后方向移动。
此时，罩19的比主体部610向后方突出的侧面部620抵接于罩引导构件430的前端部。因此，罩19以向前方移动的超声波洗净装置50的超声波洗净部100不会碰到罩19的主体部610的方式成为大致水平的状态。由此，能防止罩19的主体部610碰撞到超声波洗净装置50。
像这样，当第二滑动件450向后方向滑动时，罩19的侧面部620抵接于罩引导构件430，罩19一边敞开一边被引导向罩收纳部17b。
如图5的(b)所示，当超声波洗净装置50被拉出至最后而第一滑动件440 到达第一滑动孔421的前端部时，第二滑动件450到达第二滑动孔422的后端部。由此，罩19被收纳至罩收纳部17b的最后。罩19的下端部从罩收纳部17b稍微向前方露出。
如图10的(b)所示，在连杆保持构件420的左侧面部420a和右侧面部420b，于包围第一滑动孔421的周肋426的前端部设有上下一对突部427。此外，在各第一滑动件440，于前部的上端和下端形成有一对凹部443。由一对突部427和一对凹部443构成装置保持部428。
当超声波洗净装置50向投入口14内被拉出至最后时，一对突部427与一对凹部443卡合。超声波洗净装置50以停留在最终的拉出位置的方式由被装置保持部428保持。由此，被拉出至投入口14内的超声波洗净装置50不易向收纳部17侧移动。需要说明的是，当第一滑动件440的前部经过一对突部427的位置时，一对突部427被第一滑动件440的前部向上下挤开。
装置保持部428的保持力比移动机构92通过马达91的动力来使超声波洗净装置50移动的力弱。因此，当通过移动机构92的工作使超声波洗净装置50向后方向移动时，由装置保持部428实现的保持被解除。
当被拉出至投入口14内的超声波洗净装置50被收纳向装置收纳部17a内时，马达91向第二方向即从右侧观察超声波洗净装置50时的顺时针方向旋转，小齿轮510向同一方向旋转。当小齿轮510向第二方向旋转时，齿条520向用于将超声波洗净装置50收纳于收纳部17内的方向即前方向移动。
由此，连结构件530和第二滑动件450向前方向移动。连杆460转动，其另一端侧向前方向移动，其一端侧向后方向移动。第一滑动件440向后方向滑动，如图5的(a)所示，超声波洗净装置50被收纳于装置收纳部17a。罩19关闭，出入口18被罩19封闭。
图11是表示全自动洗衣机1的结构的框图。
全自动洗衣机1除了上述的结构以外，还具备操作部810、显示部820以及水位传感器830。
操作部810包括电源按钮811、开始按钮812、模式选择按钮813以及洗净按钮814等各种操作按钮，该电源按钮811用于接通和切断全自动洗衣机1的 电源，该开始按钮812用于开始、暂停运转，该模式选择按钮813用于从洗涤运转的多个运转模式中选择任意的运转模式，该洗净按钮814用于选择洗净运转。操作部810将与被用户操作的操作按钮对应的输入信号输出至控制部16。
显示部820具有LED等显示元件，进行由模式选择按钮813选择的运转模式的显示、洗涤运转中的过程的进展的显示、异常的显示等各种显示。
水位传感器830检测洗涤脱水桶22内即外桶20内的水位，并将与检测到的水位对应的水位信号输出至控制部16。
收纳检测开关710在检测到向收纳部17内收纳超声波洗净装置50时接通，向控制部16输出接通信号。收纳检测开关710在未检测到超声波洗净装置50的收纳的期间断开，向控制部16输出断开信号。
拉出检测开关720在检测到向投入口14内拉出超声波洗净装置50时接通，向控制部16输出接通信号。拉出检测开关720在未检测到超声波洗净装置50的拉出的期间断开，向控制部16输出断开信号。
控制部16包括微机、各种驱动电路等，基于来自操作部810、水位传感器830、收纳检测开关710、拉出检测开关720等的各个信号来控制显示部820、驱动马达31、离合机构32a、供水装置80、排水阀40、供给阀61、超声波振子111、马达91等。
全自动洗衣机1中进行各种运转模式的洗涤运转。在洗涤运转中，按顺序执行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。
在清洗过程和漂洗过程中，在洗涤脱水桶22内蓄有水的状态下，波轮24向右方向和左方向旋转。通过波轮24的旋转，洗涤脱水桶22内产生水流。在清洗过程中，通过产生的水流和水中所含的洗涤剂，洗涤物被清洗。在漂洗过程中，通过产生的水流，洗涤物被漂洗。需要说明的是，在进行清洗过程的供水时，通过供水装置80来向洗涤脱水桶22内自动投入洗涤剂。此外，在进行漂洗过程的供水时，通过供水装置80来向洗涤脱水桶22内自动投入柔顺剂。
在中间脱水过程和最终脱水过程中，洗涤脱水桶22和波轮24成为一体高速旋转。通过洗涤脱水桶22中产生的离心力的作用，洗涤物被脱水。
全自动洗衣机1中能进行由超声波洗净装置50实现的洗净运转。
在进行洗净运转的情况下，用户按下洗净按钮814选择洗净运转后，按下开始按钮812。由此，洗净运转开始。需要说明的是，在洗净运转开始时，超声波洗净装置50被收纳于装置收纳部17a内即收纳部17内。
图12的(a)是表示在洗净运转中由控制部16执行的控制处理的流程图。
参照图12的(a)，当洗净运转开始时，控制部16依次执行拉出/供水过程、洗净过程以及收纳过程(S1～S3)。
图12的(b)是表示在拉出/供水过程中由控制部16执行的控制处理的流程图。图13的(a)是表示在洗净过程中由控制部16执行的控制处理的流程图。图13的(b)是表示在收纳过程中由控制部16执行的控制处理的流程图。图14是用于对拉出/供水过程中的超声波洗净装置50的拉出工作进行说明的图。
参照图12的(b)，当拉出/供水过程开始时，控制部16使马达91向第一方向旋转，开始通过自动出入装置90来向投入口14内拉出超声波洗净装置50(S101)。接着，控制部16判定收纳检测开关710是否断开(S102)。
在超声波洗净装置50完全收纳于收纳部17内时，如图9的(a)所示，通过被检测部124的接触，收纳检测开关710接通。此时，阀可动构件230抵接于排水承接部70的后壁，贮水桶210的排水口211打开。当超声波洗净装置50向前方向即投入口14侧移动时，被检测部124离开，从而收纳检测开关710断开。此外，阀可动构件230从排水承接部70的后壁离开，排水口211被阀体220封闭，能向贮水桶210内蓄留洗净水。
在判定为收纳检测开关710断开时(S102：是)，控制部16开始使供水装置80工作，开始向贮水桶210内供给洗净水(S103)。由供水装置80生成的洗净水暂时蓄于贮留箱60。之后，通过控制部16打开供给阀61，贮留箱60内的洗净水经由供给喷嘴62被供给至贮水桶210内。由此，向贮水桶210内蓄留洗净水。
如上所述，在确认到收纳检测开关710断开后，即，在确认到排水口211呈封闭状态后，开始向贮水桶210内供给洗净水，因此能防止在排水口211打开的状态下进行洗净水的供给。
接着，控制部16判定拉出检测开关720是否接通(S104)。当超声波洗净 装置50被拉出至投入口14内时，如图9的(b)所示，通过被检测部535的接触，拉出检测开关720接通。
在本实施方式中，在拉出检测开关720接通时，即，在拉出检测开关720检测到向投入口14内拉出超声波洗净装置50时，超声波洗净装置50尚未被拉出至最后，如图14的左图所示，通过一对突部427与一对凹部443的卡合，装置保持部428存在于比保持超声波洗净装置50的位置靠近收纳部17的位置。
在判定为拉出检测开关720接通时(S102：是)，之后，控制部16等待经过规定时间(S105)。然后，在经过规定时间时(S105：是)，控制部16使马达91停止，停止向投入口14内拉出超声波洗净装置50(S106)。
当超声波洗净装置50以规定时间继续移动时，如图14的右图所示，通过一对突部427与一对凹部443的卡合，装置保持部428保持超声波洗净装置50。
当实际组装超声波洗净装置50和自动出入装置90时，根据部件的精度等，拉出检测开关720检测到拉出时的超声波洗净装置50即第一滑动件440的位置很难来到设计的位置。由此，当采用了在拉出检测开关720检测到超声波洗净装置50的拉出的定时使超声波洗净装置50的移动停止的结构时，不易高精度地使拉出的超声波洗净装置50在保持于装置保持部428的位置停止。
在本实施方式中，根据拉出检测开关720检测到超声波洗净装置50的拉出时的实际的超声波洗净装置50的位置来调整规定时间。由此，能基于由拉出检测开关720实现的拉出检测来高精度地使拉出的超声波洗净装置50在保持于装置保持部428的位置停止。
如此，当停止向投入口14内拉出超声波洗净装置50时，拉出/供水过程结束。
通常，向贮水桶210内蓄留洗净水所需的时间比从收纳部17内向投入口14内拉出超声波洗净装置50所需的时间长。因此，在拉出/供水过程结束后，继续向贮水桶210内供给洗净水。
需要说明的是，在步骤S101中，在开始向投入口14内拉出超声波洗净装置50时，控制部16判定从拉出开始起是否经过了限制时间(S107)。由于马达91不旋转等自动出入装置90的异常，可能产生超声波洗净装置50不移动的 情况。在该情况下，以收纳检测开关710不断开的方式经过限制时间。当经过限制时间时(S107：是)，控制部16中止洗净运转(S108)，进行由显示部820实现的异常告知(S109)。
当拉出/供水过程(S1)结束时，洗净过程(S2)开始。
参照图13的(a)，控制部16判定对超声波振子111开始通电的通电开始定时是否到来(S201)。
例如，在供给喷嘴62为设置于其前端部的洗净水的放出口会从上方进入贮水桶210内的结构的情况下，贮水桶210内的水位上升至放出口的下端的高度，当放出口被洗净水堵住时，来自贮留箱60内的洗净水的水压与大气压平衡，在保持供给阀61打开的状态下，来自贮留箱60的供水停止。在该情况下，在供给阀61被打开后，在经过了比向贮水桶210供给洗净水所需的时间长的规定的待机时间时，控制部16判定为通电开始定时到来。
在从向贮水桶210内蓄留洗净水起到通电开始定时到来为止的期间，由用户将被洗净物的污垢附着部分放置于贮水桶210与超声波发生体110的振动变幅杆112之间。被洗净物的污垢附着部分浸入洗净水中，浸透至被洗净物的内部的洗净水渗出表面。呈在被洗净物的表面形成有薄的水层而振动变幅杆112与该水层接触的状态。
在通电开始定时到来时(S201：是)，控制部16开始向超声波振子111通电(S202)。超声波发生体110工作，从振动变幅杆112的前端产生超声波。通过超声波的作用从被洗净物中剥离污垢。此时，通过加上洗涤剂之力，洗净力提高。
在从超声波发生体110开始工作起经过规定的运转时间时(S203：是)，控制部16停止向超声波振子111通电(S204)。如此，洗净过程结束。
当洗净过程(S2)结束时，收纳过程(S3)开始。需要说明的是，也可以是，在操作部810设有收纳按钮，在洗净过程结束后按下收纳按钮时，收纳过程开始。
参照图13的(b)，控制部16使马达91向第二方向旋转，开始通过自动出入装置90来向收纳部17内收纳超声波洗净装置50(S301)。接着，控制部 16判定收纳检测开关710是否接通(S302)。
当超声波洗净装置50完全收纳于收纳部17内时，如图9的(a)所示，通过被检测部124的接触，收纳检测开关710接通。在判定为收纳检测开关710接通时(S302：是)，控制部16使马达91停止，停止向收纳部17内收纳超声波洗净装置50(S303)。如此，收纳过程结束。
在步骤S301中，已开始向收纳部17内收纳超声波洗净装置50的控制部16判定从开始收纳起是否经过了限制时间(S304)。当因自动出入装置90的异常而发生了超声波洗净装置50不移动的情况时，以收纳检测开关710未接通的方式经过限制时间。当经过限制时间时(S304：是)，控制部16中止洗净运转(S305)，进行由显示部820实现的异常告知(S306)。
当收纳过程(S3)结束时，洗净运转结束。
需要说明的是，当超声波洗净装置50即贮水部200被收纳于收纳部17时，通过阀可动构件230的工作，阀体220从排水口211离开而排水口211打开。由此，贮水桶210内的洗净水经过排水口211向排水承接部70排出，流过排水管72、溢水管26以及排水软管41被排出机外。
＜实施方式的效果＞
以上，根据本实施方式，移动机构92通过马达91向第一方向的旋转来使收纳于收纳部17内的超声波洗净装置50向投入口14内移动，通过马达91向第二方向的旋转来使拉出至投入口14内的超声波洗净装置50向收纳部17内移动。由此，用户在使用时，可以不必手动使超声波洗净装置50从收纳部17初入。由此，超声波洗净装置50从收纳部17的出入变得容易。
此外，在收纳时，贮水桶210内的洗净水不会溅到用户的手上。而且，由于能在收纳时以适当的速度使超声波洗净装置50移动，因此洗净水不易从贮水桶210飞溅，防止收纳部17内被洗净水弄湿。
而且，根据本实施方式，移动机构92包括：小齿轮510，固定于马达91的旋转轴91a；以及齿条520，与小齿轮510啮合，通过小齿轮510的旋转而向用于将超声波洗净装置50拉出至投入口14内的方向和用于将超声波洗净装置50收纳于收纳部17内的方向直线移动。由此，能将马达91的旋转运动转换为直 线运动来使超声波洗净装置50在收纳部17与投入口14之间直线地移动。
而且，根据本实施方式，基于拉出检测开关720检测到向投入口14拉出超声波洗净装置50而使向第一方向旋转的马达91停止，基于收纳检测开关710检测到向收纳部17收纳超声波洗净装置50而使向第二方向旋转的马达91停止。由此，能将超声波洗净装置50可靠地拉出至投入口14内且能将其收纳于收纳部17内。
而且，根据本实施方式，在超声波洗净装置50被拉出至比由装置保持部428保持的位置靠近收纳部17的位置时，由拉出检测开关720检测超声波洗净装置50的拉出，并在从检测到超声波洗净装置50的拉出起经过规定时间后使马达91停止。由此，通过根据拉出检测开关720检测到超声波洗净装置50的拉出时的实际的超声波洗净装置50的位置来调整规定时间，能基于由拉出检测开关720实现的拉出检测来高精度地使拉出的超声波洗净装置50在保持于装置保持部428的位置停止。
而且，根据本实施方式，在超声波洗净装置50通过马达91向第一方向的旋转而向投入口14侧移动的期间，开始由供水装置80实现的洗净水的供给。由此，能缩短从洗净运转开始起到向贮水桶210内的洗净水的供给完成而超声波发生体110能进行工作为止所花的时间。
而且，根据本实施方式，通过移动机构92，与超声波洗净装置50向收纳部17的出入动作联动地对罩19进行开闭。由此，能谋求实现使超声波洗净装置50自动出入的功能和对罩19自动进行开闭的功能的结构的简化。
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，本发明的实施方式除了上述以外还可以进行各种变更。
例如，在本实施方式中，移动机构92采用了包括左右两个连杆机构410、连杆保持构件420、罩引导构件430以及齿条小齿轮机构500的结构。然而，移动机构92只要能通过马达91向第一方向的旋转来使收纳于收纳部17内的超声波洗净装置50向投入口14内移动并通过马达91向第二方向的旋转来使拉出至投入口14内的超声波洗净装置50向收纳部17内移动，可以是任意结构。例如，移动机构92也可以采用齿条520和小齿轮510配置于超声波洗净装置50的后 方且齿条520的前端部直接连结或经由连结构件连结于贮水部200或基体部300的后部的结构。
在该情况下，马达91配置于超声波洗净装置50的后方，小齿轮510固定于马达91的旋转轴91a。通过马达91向第一方向的旋转，齿条520向前方向即拉出方向移动，由此超声波洗净装置50被拉出至投入口14内，通过马达91向第二方向的旋转，齿条520向后方向即收纳方向移动，由此超声波洗净装置50被收纳于收纳部17内。
不过，在移动机构92采用上述实施方式的结构的情况下，由于能将齿条小齿轮机构500和马达91配置于构成收纳部17的上部的顶面部430a，因此上面板12的后部的前后方向的尺寸不会变大。
而且，在本实施方式中，连结构件530连结于第二滑动件450从而第二滑动件450随着齿条520的移动而滑动。然而，也可以采用连结构件530连结于第一滑动件440从而第一滑动件440随着齿条520的移动而滑动的结构。
而且，在本实施方式中，检测超声波洗净装置50被拉出至投入口14内的情况的拉出检测部使用了拉出检测开关720，检测超声波洗净装置50被收纳于收纳部17内的情况的收纳检测部使用了收纳检测开关710。然而，拉出检测部和收纳检测部也可以使用其他结构的传感器，例如光电传感器、簧片开关。
而且，在本实施方式中，移动机构92采用了与超声波洗净装置50向收纳部17的出入动作联动地使罩19开闭的结构。然而，移动机构92也可以采用不使罩19开闭的结构。在该情况下，例如，可以采用如下结构：罩19不连结于第二滑动件450而可转动地固定于其他支承部，由被拉出的超声波洗净装置50的超声波洗净部100按压而向上方转动并敞开。
而且，在本实施方式中，由供水装置80生成的洗净水短暂蓄于贮留箱60，之后从贮留箱60供给至贮水桶210。然而，也可以不设置贮留箱60而从供水装置80直接向贮水桶210供给洗净水。
而且，在本实施方式中，罩19沿上下方向开闭。然而，罩19也可以沿左右方向开闭。
而且，在本实施方式中，移动机构92使敞开的罩19收纳于罩收纳部17b。 然而，移动机构92也可以不使敞开的罩19收纳于罩收纳部17b。
而且，在本实施方式中，收纳部17设于上面板12的后部，超声波洗净装置50向前方被拉出。然而，也可以将收纳部17设于上面板12的左部或右部并向右方向或左方向拉出超声波洗净装置50。
而且，只要具有蓄留洗净水的贮水桶210并使超声波发生体110产生的超声波作用于浸入该贮水桶210内的洗净水中的被洗净物来去除附着于被洗净物的污垢，超声波洗净装置50可以采用与上述实施方式的结构不同的结构。
而且，在本实施方式中，含有洗涤剂的水蓄于贮水桶210来作为洗净水。然而，也可以是不含洗涤剂的水蓄于贮水桶210来作为洗净水。
而且，在本实施方式中，示出了具备超声波洗净装置50的全自动洗衣机1。然而，本发明也可以用于全自动洗衣机1以外的洗衣机，例如具有烘干功能的全自动洗干一体机。
此外，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。
