Description

洗衣机 技术领域
本发明涉及洗衣机。
背景技术
专利文献1中记载了一种洗衣机，其具备利用超声波来洗净被洗净物的超声波洗净装置。
在专利文献1的洗衣机中，在具有投入口的上面板的内部设有收纳超声波洗净装置的收纳部。在进行由超声波洗净装置实现的洗净运转时，超声波洗净装置从收纳部被拉出到投入口的内侧。
超声波洗净装置具备：贮水桶，蓄留含洗涤剂的水来作为洗净水；以及超声波发生体，产生超声波。被洗净物的污垢附着部分浸入贮水桶内的洗净水中。由超声波发生体产生的超声波作用于浸透了洗净水的污垢附着部分，从被洗净物中去除污垢。此时，再加上洗涤剂的效果，因此可以期待提高洗净性能。
而且，超声波洗净装置具备：阀体，对形成于贮水桶的后表面的排水口进行开闭；以及阀切换机构，切换阀体。当超声波洗净装置收纳于收纳部时，通过阀切换机构的动作，阀体打开，贮水桶内的洗净水从排水口排出。此外，在阀切换机构包括操作部且在从收纳部拉出了超声波洗净装置的状态下操作了操作部的情况下，也通过阀切换机构的动作来使阀体打开，使贮水桶内的洗净水从排水口排出。从排水口排出的洗净水，由配置于收纳部的排水承接部承接，然后经过排水软管排出到机外。
在上述的洗衣机中，洗净运转中使用的洗净水即洗净水中所含的洗涤剂在洗净运转结束后直接被废弃到机外。因此，难以将洗净运转中使用过的洗涤剂用于后续的洗涤运转，难以降低洗涤运转中洗涤剂的使用量。

在箱体10内配置有上表面开口的外桶20。外桶20由具有防振装置的四根吊棒21弹性地悬挂支承。在外桶20内配置有上表面开口的洗涤脱水桶22。洗涤脱水桶22以沿铅垂方向延伸的旋转轴为中心旋转。在洗涤脱水桶22的内周面遍及整周地形成有许多脱水孔22a。在洗涤脱水桶22的上部设有平衡环23。在洗涤脱水桶22的底部配置有波轮24。在波轮24的表面呈辐射状地设有多个叶片24a。需要说明的是，洗涤脱水桶22相当于本发明的“洗涤桶”。
上面板12配置于洗涤脱水桶22的上方，经过投入口14向洗涤脱水桶22内投入洗涤物。
在外桶20的外底部配置有产生驱动洗涤脱水桶22和波轮24的转矩的驱动单元30。驱动单元30包括驱动马达31和传递机构部32。传递机构部32具有离合机构32a，通过由该离合机构32a实现的切换操作，在清洗过程和漂洗过程中将驱动马达31的转矩仅传递给波轮24而仅使波轮24旋转，在脱水过程中将驱动马达31的转矩传递给波轮24和洗涤脱水桶22而使波轮24和洗涤脱水桶22一体地旋转。
在外桶20的外底部形成有排水口部20a。在排水口部20a设有排水阀40。排水阀40连接于排水软管41。当打开排水阀40时，蓄于洗涤脱水桶22和外桶20的水经过排水软管41向机外排出。
在外桶20的上部形成有溢水口20b。当外桶20内蓄有规定的溢水水位以上的水时，水会从溢水口20b排出。在外桶20的外表面以覆盖溢水口20b的方式设有溢水承接部25。在溢水承接部25的底部连接有溢水管26的一端。溢水管26的另一端连接于排水软管41。从溢水口20b排出的水被溢水承接部25承接 后经过溢水管26流向排水软管41。

在底板部241，在与贮水桶210的槽部213和收容部214对应的部分形成有大致方形的开口部246。在开口部246的与收容部214对应的部分沿左右方向架设有罩部247。
在底板部241，于开口部246的后缘部设有弹簧安装部248。弹簧安装部248 具有向前方延伸的轴248a。压缩弹簧260的后端插入轴248a。压缩弹簧260收容于收容部214，其前端与收容部214的前壁面214a抵接。压缩弹簧260的前侧部分被罩部247从下方覆盖。需要说明的是，压缩弹簧260相当于本发明的施力构件。压缩弹簧260以外的弹簧、其他施力构件也可以用于对阀体230的施力。
在底板部241，于开口部246的前缘部设有阀安装部249。阀安装部249收容于隆起部211的凹陷部分211b。在阀安装部249装配有阀体230。
在连结部245，于前端部形成有沿前后方向延伸的长孔245a。长孔245a与形成于贮水部200的里侧的安装凸台201配合。穿过长孔245a的螺钉270以不压到连结部245的方式固定于安装凸台201。由此，连结部245虽然在上下左右方向上被固定，但能在长孔245a的长度范围内向前后方向移动。
操作部250一体地形成于阀可动构件240的连结部245的前端部。在贮水部200，于左侧面的前部设有方形的操作窗202。操作部250从操作窗202面向外部。在操作部250的前端部形成有沿上下方向延伸的肋251。肋251是用户对操作部250进行移动操作时勾住手指的部分。
当阀体230从前方闭塞排水口212时，压缩弹簧260处于压缩状态，阀体230被压缩弹簧260经由阀可动构件240向后方向即闭塞方向施力。贮水部200中，贮水桶210的后方敞开，阀可动构件240的后端部即后板部244比贮水部200向后方突出。
贮水部200从前方装接于基体部300。在贮水部200装接于基体部300的状态下，超声波发生体110的振动变幅杆112的前端面的位置比贮水桶210的上表面的位置稍低，振动变幅杆112的前端部呈进入贮水桶210内的状态。
全自动洗衣机1中能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内蓄留有水的状态下，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。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。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， 由供水装置80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，由供水装置80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24一体地高速旋转。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，如图2的(a)所示，用户将超声波洗净装置50从收纳部17拉出。
图8是超声波洗净装置50处于从收纳部17拉出的状态时的超声波洗净装置50和排水承接部70的侧剖图。图8中画出了供给喷嘴62的前端部。此外，图8中，收纳部17的出入口18用双点划线表示。
如图8所示，当超声波洗净装置50处于被拉出到投入口14内的状态时，作为超声波洗净装置50的一部分的贮水部200即贮水桶210的后部和基体部300留在收纳部17内。在开闭机构220中，压缩弹簧260经由阀可动构件240向闭塞方向对阀体230施力。由此，阀体230将排水口212闭塞，排水口212呈封闭状态。排水口212离开收纳部17，在投入口14内位于洗涤脱水桶22的上方。
用户进行规定的开始操作以开始洗净运转。
当洗净运转开始时，通过供水装置80进行向贮水桶210内的洗净水的供给。即，由供水装置80生成的洗净水短暂蓄留于贮留箱60。然后，打开供给阀61，贮留箱60内的洗净水经由供给喷嘴62供给到贮水桶210内。
如图8所示，供给喷嘴62的前端部从上方与留在收纳部17的贮水桶210的后部重叠。在供给喷嘴62的前端部形成有向下方突出的圆筒状的放出口62a，放出口62a的下端部进入到贮水桶210内。
从供给喷嘴62向贮水桶210的后部放出洗净水来向贮水桶210内蓄留洗净水。如图8的单点划线所示，当贮水桶210内的水位上升至放出口62a的下端的高度而放出口62a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相平衡。由此，保持供给阀61打开的状态停止从贮留箱60供水。
当贮水桶210内蓄有洗净水时，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被浸入洗净水中，浸透到被洗净物的内部的洗净水渗出表面。呈现出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。
当供给阀61打开后经过规定的待机时间时，对超声波振子111进行通电，超声波发生体110工作。从振动变幅杆112的前端产生超声波，通过超声波的作用而从被洗净物中剥离污垢。此时，通过加上洗涤剂的效力，洗净力提高。
当超声波发生体110开始工作后经过规定的运转时间时，超声波发生体110停止工作，洗净运转结束。
用户如图2的(b)和(c)所示将超声波洗净装置50收纳于收纳部17。
图9是超声波洗净装置50处于收纳于收纳部17的状态时的超声波洗净装置50和排水承接部70的侧剖图。图9中，收纳部17的出入口18用双点划线表示。
如图9所示，当超声波洗净装置50即贮水部200收纳于收纳部17时，在开闭机构220中，与贮水部200一起向后方即收纳方向移动的阀可动构件240的后板部244与排水承接部70的后表面部70a抵接，被后表面部70a推压而克服压缩弹簧260的施加力向贮水部200的前方即拉出方向移动。与阀可动构件240连结的阀体230向贮水桶210的排水口212的前方即远离排水口212的远离方向移动，排水口212被打开。
在此，阀可动构件240在向收纳方向进行了移动时，在排水口212进入排水承接部70的上方后与后表面部70a抵接。因此，在排水口212开始打开时，排水口212位于排水承接部70的上方。需要说明的是，排水承接部70的后表面部70a相当于本发明的抵接部。
如图9的箭头所示，贮水桶210内的洗净水经过排水口212向排水承接部70排出。排出到排水承接部70的洗净水从排出孔71排出，流过排水管72、溢水管26以及排水软管41向机外排出。此时，供给阀61已被打开，残留在贮留箱60内的洗净水也经过贮水桶210向机外排出。
在洗净运转结束时，在将洗净运转中使用过的洗净水即洗净水中所含的洗涤剂再利用于洗涤运转的情况下，用户在超声波洗净装置50被拉出到投入口14 内的状态下进行使操作部250向前方移动的移动操作。
图10是在超声波洗净装置50从收纳部17拉出的状态下操作部250被进行了移动操作时的超声波洗净装置50和排水承接部70的侧剖图。在图10中，收纳部17的出入口18用双点划线表示。
当操作部250被移动操作时，在开闭机构220中，与贮水部200移动到收纳部17内时同样地，阀可动构件240相对于贮水部200向拉出方向移动。由此，阀体230相对于贮水桶210的排水口212向远离方向移动，排水口212被打开。
此时，排水口212位于洗涤脱水桶22的上方。因此，如图10的箭头所示，从贮水桶210内经过排水口212排出的洗净水被排出到洗涤脱水桶22内。排水口212向前方即拉出方向开口，因此洗净水从排水口212向洗涤脱水桶22的内侧方向排出。
需要说明的是，供给阀61已被打开，残留于贮留箱60内的洗净水也经过贮水桶210向洗涤脱水桶22内排出。
这样，用户能将洗净运转中使用过的洗涤剂用于该洗净运转后续进行的洗涤运转。
＜实施方式的效果＞
以上，根据本实施方式，当超声波洗净装置50收纳于收纳部17内时，贮水桶210的排水口212在收纳部17内位于排水承接部70的上方，当超声波洗净装置50被拉出到投入口14内时，该排水口212离开收纳部17而位于洗涤脱水桶22的上方。
由此，通过在超声波洗净装置50收纳于收纳部17内的状态下由开闭机构220打开排水口212，能将贮水桶210内的洗净水废弃到机外。而且，通过在超声波洗净装置50被拉出到投入口14内的状态下由开闭机构220打开排水口212，能将贮水桶210内的洗净水排出到洗涤脱水桶22内，能将洗净水中所含的洗涤剂用于洗涤运转。
而且，根据本实施方式，排水口212向超声波洗净装置50从收纳部17拉出的拉出方向开口，因此能使洗净水向洗涤脱水桶22的内侧方向排出，能防止洗净水向洗涤脱水桶22外部泄漏。
而且，根据本实施方式，排水口212在形成于贮水桶210的底面部210a的隆起部211中形成于朝向后方即收纳方向的壁面211a，与隆起部211的凹陷部分211b相连。而且，开闭机构220包括配置于凹陷部分211b并从贮水桶210的外侧闭塞排水口212的阀体230。
根据该结构，能抑制形成有排水口212的壁面211a和阀体230向贮水桶210的下方突出的量，因此会缩短贮水桶210与排水承接部70的距离。由此，能紧凑地配置包括超声波洗净装置50和排水承接部70的单元，能紧凑地配置收纳部17。
而且，根据本实施方式，开闭机构220采用了如下结构：在超声波洗净装置50向收纳方向进行了移动时阀可动构件240与设于收纳部17内的排水承接部70的后表面部70a抵接，被该后表面部70a推压而向拉出方向移动，使阀体230向远离排水口212的远离方向移动。
因此，能通过将超声波洗净装置50收纳于收纳部17来自动地将贮水桶210内的洗净水排出到机外。而且，阀可动构件240在向收纳方向进行了移动时在排水口212进入排水承接部70的上方后与后表面部70a抵接，因此能在排水口212开始打开时可靠地使排水口212位于排水承接部70的上方，能防止洗净水向洗涤脱水桶22侧泄漏。
而且，根据本实施方式，开闭机构220包括进行用于使阀可动构件240向拉出方向移动并使阀体230向远离方向移动的操作的操作部250。因此，用户能通过在超声波洗净装置50被拉出到投入口14内的状态下操作操作部250来使排水口212打开而将贮水桶210内的洗净水排出到洗涤脱水桶22内。
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形。
例如，在上述实施方式中，开闭机构220采用了具备阀体230、阀可动构件240、操作部250以及压缩弹簧260的结构。但是，只要能使排水口212开闭，开闭机构220可以是任意的结构。例如，开闭机构220也可以采用包括配置于排水口212的电磁阀并通过电磁阀的开闭来开闭排水口212的结构。
而且，在上述实施方式中，排水口212向超声波洗净装置50的拉出方向开 口。但是，排水口212开口的方向不限定于上述方向，例如，排水口212也可以向下方开口。
而且，在上述实施方式中，隆起部211形成于贮水桶210的底面部210a，排水口212形成于该隆起部211的壁面211a。但是，只要是在贮水桶210的底部设有排水口212，就不必采用上述结构。例如，也可以采用在贮水桶210的底面部210a形成向下方凹陷的凹部并在凹部的底面、周壁面形成排水口21的结构。
而且，在上述实施方式中，排水承接部70的后表面部70a作为供阀可动构件240抵接的抵接部发挥功能。但是，只要抵接部是配置于收纳部17内供阀可动构件240抵接，就可以是任意的结构。
而且，在上述实施方式中，由供水装置80生成的洗净水短暂蓄留在贮留箱60，然后从贮留箱60向贮水桶210供给。但是，也可以不设置贮留箱60而将洗净水从供水装置80直接供给至贮水桶210。
而且，在上述实施方式中，示出了具备超声波洗净装置50的全自动洗衣机1。但是，本发明也适用于全自动洗衣机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，本发明的实施方式能在技术方案所示的技术思想的范围内适当地进行各种变更。
