Description

洗衣机 技术领域
本发明涉及一种洗衣机。
背景技术
例如专利文献1中记载了一种能将液体洗涤剂自动投入洗涤兼脱水桶内的洗衣机。
专利文献1的洗衣机具备设置于外壳内并收容液体洗涤剂的洗涤剂盒。洗涤剂盒通过由洗涤剂盒盖关闭补充洗涤剂的补充口来封闭内部，并且具有空气流入口和液体排出口。空气流入口与空气泵相连。当空气泵工作时，密闭的洗涤剂盒内的气压升高，洗涤剂盒内的洗涤剂被从液体排出口挤出而投入洗涤兼脱水桶内。用户不用在每次洗涤运转时都向洗衣机投入一次量的洗涤剂，很方便。
如上所述，作为将洗涤剂自动投入洗涤剂盒内的结构，能采用通过来自水龙头的水来将洗涤剂从洗涤剂盒向流向洗涤脱水桶的水路内导入并通过流过水路的水使导入的洗涤剂流入洗涤脱水桶的结构。该结构中，水路与洗涤剂盒之间的洗涤剂导入路径被三通阀等切换部在打开状态与关闭状态之间切换。当洗涤剂导入水路内时，通过切换部来关闭导入路径，向水路内供水。
但是，这样的结构中，在因切换部发生异物堵塞等不良情况而导致导入路径无法完全关闭的情况下，供给至水路的一部分水可能会进入洗涤剂盒内。当在像这样洗涤剂盒内进水的状态下继续供水时，存在例如从设置于洗涤剂盒的洗涤剂投入口溢水的隐患。

本方案的洗衣机中，可以采用所述控制部中止向所述水路的供水来作为所述异常处理的结构。
这里，所谓的“中止供水”在停止供水来获取第一检测信号的情况下表示 不恢复供水，在不停止供水来获取第一检测信号的情况下表示停止供水。
根据上述结构，能防止从盒体内因初始的供水而进水的状态进一步进水。
本方案的洗衣机中，可以采用所述控制部向告知部进行异常告知来作为所述异常处理的结构。
根据上述结构，能向用户通知盒体内可能发生了进水。
本方案的洗衣机中，可以采用如下结构：所述控制部在从开始向所述水路供水起经过规定时间时停止供水并获取所述第一检测信号。

具体实施方式
以下，参照附图对本发明的洗衣机的一个实施方式进行说明。
图1是全自动洗衣机1的侧剖图。
参照图1，全自动洗衣机1具备构成外轮廓的箱体10。箱体10包括上下表面敞开的方形筒状的机身部11、覆盖机身部11的上表面的上面板12以及支承机身部11的脚台13。在上面板12形成有洗涤物的投入口14。投入口14由自由开闭的上盖15覆盖。在上面板12的前部，于内部配置有控制单元16。控制单元16控制全自动洗衣机1的洗涤运转和超声波清洗装置50的清洗运转。
上表面开口的外桶20由具有防振装置的四根吊棒21弹性地悬挂支承在箱体10内。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进行旋转。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的上部设置有平衡环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置有多个叶片24a。需要说明的是，洗涤脱水桶22相当于本发明的“洗涤桶”。
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设置有排水阀40。排水阀40与排水软管41连接。当排水阀40打开时，蓄于洗涤脱水桶22和外桶20的水经过排水软管41排出到机外。
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的方式设置有溢水承接部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的另一端与排水软管41连接。从溢水口20b排出的水被溢水承接部25承接之后经过溢水管26流向排水软管41。
在上面板12的后部的大致中央配置有超声波清洗装置50。超声波清洗装置50主要进行用于在全自动洗衣机1进行洗涤之前去除局部附着于被清洗物的污垢的清洗运转。
在上面板12的后部，于超声波清洗装置50的后方配置有贮留箱60，于超声波清洗装置50的下方配置有排水承接部70。贮留箱60中蓄有要供给至超声波清洗装置50的贮水桶210的含有洗涤剂的水来作为清洗水。在贮留箱60设置有对来自箱内的清洗水的流出口进行开闭的供给阀61。

在上面板12的后部，以包围超声波清洗装置50的方式配置有供水装置80。供水装置80与水龙头相连，具有向洗涤脱水桶22内进行供水的功能。而且，供水装置80也作为将液体洗涤剂和柔顺剂自动投入洗涤脱水桶22内的自动投入装置发挥作用。进而，供水装置80还具备向贮留箱60供给清洗水的功能。需要说明的是，洗涤剂和柔顺剂是用于洗涤的液剂，后面有时会将洗涤剂和柔顺剂统称为“液剂”。
图2的(a)是超声波清洗部100和贮水部200收纳于收纳部17的状态的超声波清洗装置50和上面板12的立体图。图2的(b)和(c)是超声波清洗部100和贮水部200从收纳部17拉出的状态的超声波清洗装置50和上面板12的主要部分的立体图。图2的(c)中，为了看到收纳部17的内部，省略了罩17b的图示。
参照图2的(a)至(c)，在上面板12，于后部的中央部设置有收纳超声波清洗装置50的收纳部17。上面板12中收纳部17的前方作为出入口17a开口。在出入口17a设置有罩17b。
超声波清洗装置50具备超声波清洗部100、贮水部200以及主体部300。超声波清洗部100具有产生超声波的超声波发生体110，并由主体部300保持。在贮水部200设置有位于超声波发生体110的下方并能蓄留清洗水的贮水桶210。从与贮留箱60的供给阀61相连的供给喷嘴62向贮水桶210供给清洗水。贮水部200可脱离地装接于主体部300。
如图2的(a)所示，进行清洗运转时，超声波清洗装置50被从收纳部17向前方拉出并，向上面板12的投入口14的内侧伸出。另一方面，如图2的(b)和(c)所示，不进行清洗运转时，超声波清洗装置50收纳于收纳部17。收纳部17的出入口17a由罩17b关闭。
如图2的(a)所示，在上面板12，于投入口14的左后方形成有漏斗状的洗涤剂注入口18，于投入口14的右后方形成有漏斗状的柔顺剂注入口19。形成于洗涤剂注入口18的中央部的开口18a与后述的洗涤剂盒400的投入口相连。过滤器410经过开口18a装接于投入口。此外，形成于柔顺剂注入口19的中央 部的开口19a与后述的柔顺剂盒500的投入口相连。过滤器510经过开口19a装接于投入口。液体洗涤剂经过洗涤剂注入口18被投入洗涤剂盒400内，液体的柔顺剂经过柔顺剂注入口19被投入柔顺剂盒500内。
图3是示意性地表示供水装置80的结构的图。图4的(a)和(b)分别是洗涤剂盒400的俯视图和仰视图，图4的(c)是图4的(a)的A－A′剖视图。图5的(a)和(b)分别是柔顺剂盒500的俯视图和仰视图，图5的(c)是图5的(a)的B－B′剖视图。
如图3所示，供水装置80具备洗涤剂盒400、柔顺剂盒500以及供水单元600。
洗涤剂盒400中能贮存液体洗涤剂。柔顺剂盒500中能贮存液体柔顺剂。供水单元600从洗涤剂盒400和柔顺剂盒500分别摄入洗涤剂和柔顺剂并通过供给向洗涤脱水桶22的水来使摄入的洗涤剂和柔顺剂流入洗涤脱水桶22内。如此，供水单元600将洗涤剂盒400内的洗涤剂和柔顺剂盒500内的柔顺剂投入洗涤脱水桶22内。洗涤剂盒400和柔顺剂盒500相当于本发明的“盒体”。
如图4的(a)和(b)所示，洗涤剂盒400例如由树脂材料形成，具有前后长的箱状。在洗涤剂盒400的上表面，于前侧形成有圆形的投入口401。在投入口401装接有过滤器410。过滤器410捕获从投入口401进入洗涤剂盒400内的异物。在洗涤剂盒400的底面，于前侧形成有向下方突出的圆形的排出部402。在排出部402的周面形成有向后方延伸的圆筒状的排出口403。
如图4的(c)所示，为了检测到该盒体内的洗涤剂的剩余量变少的情况，洗涤剂盒400具备洗涤剂电极单元420。洗涤剂电极单元420由一对电极端子421、422即第一电极端子421和第二电极端子422构成。
第一电极端子421和第二电极端子422由钢等具有导电性的材料形成，包括圆棒状的端子部421a、422a和设置于端子部421a、422a的上端部的头部421b、422b。在各个端子部421a、422a的上部形成有外螺纹。此外，在各个头部421b、422b形成有十字形状的槽，以便能用螺丝刀来旋转第一电极端子421和第二电极端子422。
在洗涤剂盒400的顶面部，以沿左右方向排列的方式形成有向盒体的内部 突出的第一装配凸台404和第二装配凸台405。第一电极端子421和第二电极端子422穿过第一装配凸台404和第二装配凸台405从上方插入洗涤剂盒400的内部。这时，具有外螺纹的各个端子部421a、422a的上部一边转动一边穿过第一装配凸台404和第二装配凸台405而被固定。如此一来，第一电极端子421和第二电极端子422被固定至洗涤剂盒400的顶面部。第一电极端子421和第二电极端子422的端子部421a、422a从洗涤剂盒400的顶面部向下方延伸，其前端位于洗涤剂盒400的底面部附近。第一电极端子421与第二电极端子422的间隔比较小，例如设定为十几毫米左右。
在洗涤剂盒400内的液位高于规定液位L1而一对电极端子421、422之间充分介有洗涤剂时，一对电极端子421、422之间产生的阻值相对较小，在洗涤剂盒400内的液位低于规定液位L1而一对电极端子421、422之间几乎不介有或完全不介有洗涤剂时，由于介于两者之间的基本是空气，因此在一对电极端子421、422之间产生的阻值相对较大。
如图5的(a)和(b)所示，柔顺剂盒500例如由树脂材料形成，具有前后长的箱状。在柔顺剂盒500的上表面，于前侧形成有圆形的投入口501。在投入口501装接有过滤器510。过滤器510捕获从投入口501进入柔顺剂盒500内的异物。在柔顺剂盒500的底面，于前侧形成有向下方突出的圆形的排出部502。在排出部502的周面形成有向后方延伸的圆筒状的排出口503。
如图5的(c)所示，为了检测到该盒体内的柔顺剂的剩余量变少的情况，柔顺剂盒500具备柔顺剂电极单元520。柔顺剂电极单元520由一对电极端子521、522即第一电极端子521和第二电极端子522构成。
第一电极端子521和第二电极端子522的结构与洗涤剂电极单元420的一对电极端子421、422相同，包括具有外螺纹的端子部521a、522a和具有十字形状的槽的头部521b、522b。
与洗涤剂盒400一样，在柔顺剂盒500的顶面部形成有第一装配凸台504和第二装配凸台505。第一电极端子521和第二电极端子522穿过这些装配凸台504、505从上方插入柔顺剂盒500的内部，并且固定于这些装配凸台504、505。第一电极端子521和第二电极端子522的端子部521a、522a从柔顺剂盒500的顶面部向下方延伸，其前端位于柔顺剂盒500的底面部附近。第一电极端子521 与第二电极端子522的间隔比较小，例如设定为十几毫米左右。
在柔顺剂盒500内的液位高于规定液位L2而一对电极端子521、522之间充分介有柔顺剂时，一对电极端子521、522之间产生的阻值相对较小，在柔顺剂盒500内的液位低于规定液位L2而一对电极端子521、522之间几乎不介有或完全不介有柔顺剂时，由于介于两者之间的基本是空气，因此一对电极端子521、522之间产生的阻值相对较大。
参照图3，供水单元600包括：水路构件610、供水阀620、第一三通阀630、第二三通阀640、第三三通阀650以及泵660。第一三通阀630和第二三通阀640相当于本发明的“切换部”。
在水路构件610设置有注水室611。在注水室611的底部，于前端部形成有注水口611a。注水口611a面向洗涤脱水桶22的上方。
在水路构件610形成有与注水室611相连的第一水路612和第二水路613，并且设置有流向第一水路612的水的流入口614和流向第二水路613的水的流入口615。进而，在水路构件610形成有为了向贮留箱60内供水而从第一水路612分支的分支水路616。分支水路616的流出口616a与贮留箱60的流入口连接。需要说明的是，第一水路612相当于本发明的“水路”。
在第一水路612中从流入口614到注水室611的路径的中途，从上游开始按顺序配置有第二三通阀640、第一三通阀630、泵660以及第三三通阀650。因此，第一水路612在这些第二三通阀640、第一三通阀630、泵660以及第三三通阀650的位置被隔开，在各自的位置具有上游侧连接口617a、617b、617c、617d和下游侧连接口618a、618b、618c、618d。

全自动洗衣机1除了上述的结构以外，还具备操作部710和显示部720。此外，控制单元16包括：控制部801、存储部802、操作检测部803、洗涤剂量检测部804、柔顺剂量检测部805、显示驱动部806、马达驱动部807、离合器驱动部808、六个阀驱动部809～814、泵驱动部815以及发生体驱动部816。洗涤剂量检测部804和柔顺剂量检测部805相当于本发明的“检测部”。
操作部710包括电源接通按钮711、电源断开按钮712、开始按钮713、模式选择按钮714、清洗按钮715、洗涤剂投入按钮716、柔顺剂投入按钮717等各种操作按钮。电源接通按钮711和电源断开按钮712分别是用于对全自动洗衣机1接通和断开电源的按钮。开始按钮713是用于使洗涤运转和清洗运转开始的按钮。模式选择按钮714是用于从洗涤运转的多个运转模式中选择任意的运转模式的按钮。清洗按钮715是用于选择清洗运转的按钮。洗涤剂投入按钮716是用于选择是否设定洗涤剂的自动投入并在设定为自动投入的情况下将洗涤剂的量设为正常、量多、量少中的任一者的按钮。柔顺剂投入按钮717是用于选择是否设定柔顺剂的自动投入并在设为自动投入的情况下将柔顺剂的量设 定为正常、量多、量少中的任一者的按钮。
显示部720包括多个LED和七段显示器，进行由模式选择按钮714选择的运转模式的显示、洗涤运转的进展程度或剩余时间的显示、洗涤剂按投入钮716和柔顺剂投入按钮717的设定结果的显示即“普通”、“量多”、“量少”以及“无”的任一者的设定显示等。进而，显示部720进行表示需要补充洗涤剂和柔顺剂的显示、表示洗涤剂盒400内或柔顺剂盒500内发生了进水的异常的显示。显示部720相当于本发明的“告知部”。
操作检测部803向控制部801输出与操作部710的各种操作按钮中被用户操作了的操作按钮对应的操作信号。
洗涤剂量检测部804与洗涤剂电极单元420的一对电极端子421、422连接。洗涤剂量检测部804包括矩形波发生电路，设为向控制部801输出具有与一对电极端子421、422中产生的阻值对应的高电压的脉冲宽度的脉冲信号的电路结构。例如，在洗涤剂盒400内的液位高于规定液位L1而一对电极端子421、422之间的阻值处于相对较低的状态时，高电压的脉冲宽度相对变宽，在洗涤剂盒400内的液位低于规定液位L1而一对电极端子421、422之间的阻值处于相对较高的状态时，高电压的脉冲宽度相对变窄。
柔顺剂量检测部805与柔顺剂电极单元520的一对电极端子521、522连接。柔顺剂量检测部805包括矩形波发生电路，设为向控制部801输出具有与一对电极端子521、522中产生的阻值对应的高电压的脉冲宽度的脉冲信号的电路结构。例如，在柔顺剂盒500内的液位高于规定液位L2而一对电极端子521、522之间的阻值处于相对较低的状态时，高电压的脉冲宽度相对变宽，在柔顺剂盒500内的液位低于规定液位L2而一对电极端子521、522之间的阻值处于相对较高的状态时，高电压的脉冲宽度相对变窄。
洗涤剂和柔顺剂的阻值根据其种类而不同。因此，当贮存在洗涤剂盒400内的洗涤剂的种类变更时，随之，洗涤剂盒400内的液位高于规定液位L1时的来自洗涤剂量检测部804的脉冲信号的高电压的脉冲宽度可能发生变化。同样地，当贮存在柔顺剂盒500内的柔顺剂的种类变更时，随之，柔顺剂盒500内的液位高于规定液位L2时的来自柔顺剂量检测部805的脉冲信号的高电压的脉冲宽度可能发生变化。
需要说明的是，后面的说明中，将“高电压的脉冲宽度”简称为“脉冲宽度”。
显示驱动部806、马达驱动部807、离合器驱动部808、六个阀驱动部809～814、泵驱动部815以及发生体驱动部816分别根据来自控制部801的控制信号来驱动显示部720、驱动马达31、离合机构32a、供水阀620、第一三通阀630、第二三通阀640、第三三通阀650、供给阀61、排水阀40、泵660以及超声波发生体110。
存储部802包括EEPROM(带电可擦可编程只读存储器)、RAM(随机存取存储器)等。存储部802中存储有用于执行各种运转模式的洗涤运转和由超声波清洗装置50实现的清洗运转的程序。此外，存储部802中存储有用于这些程序的执行的各种参数、各种控制标记。
控制部801包括CPU(中央处理器)等，基于来自操作检测部803、洗涤剂量检测部804、柔顺剂量检测部805等的各个信号，根据存储于存储部802的程序来控制显示驱动部806、马达驱动部807、离合器驱动部808、六个阀驱动部809～814、泵驱动部815、发生体驱动部816等。
全自动洗衣机1能进行各种运转模式的洗涤运转。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。
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顺时针和逆时针旋转。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。
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。
在基于洗涤剂投入按钮716的操作设定了自动投入洗涤剂的情况下，在清洗过程中的供水时，洗涤剂通过供水装置80被自动投入洗涤脱水桶22内。这时，第三三通阀650被切换为使入水口651与第一出水口652连通的状态，第一水路612成为与贮留箱60隔断并与注水室611相连的状态。此外，第二三通阀640被切换为使第一入水口641与出水口643连通的状态，第一水路612成 为在第二三通阀640的位置相连的状态。
首先，第一三通阀630被切换为使第二入水口632与出水口633连通的状态。由此，由洗涤剂供给管430实现的第一水路612与洗涤剂盒400之间的洗涤剂导入路径成为打开状态。泵660工作，第一水路612内的泵660的上游侧的空气被抽吸，上游侧变为负压。由此，如图3的单点划线所示，洗涤剂盒400内的液体洗涤剂经由洗涤剂供给管430被抽吸至第一水路612内。与泵660的工作时间对应量的洗涤剂蓄于第一水路612内。
接着，第一三通阀630被切换为使第一入水口631与出水口633连通的状态。由此，由洗涤剂供给管430实现的第一水路612与洗涤剂盒400之间的洗涤剂导入路径成为关闭状态。而且，第一水路612成为在第一三通阀630的位置相连的状态。如图3的实线箭头所示，供水阀620的第一阀621打开，来自水龙头的水被供给至第一水路612内。流过第一水路612内的水冲走蓄于第一水路612内的洗涤剂。被水冲走的洗涤剂与水一起流向注水室611，从注水口611a投入洗涤脱水桶22内。
进而，供水阀620中，第一阀621打开的同时第二阀622打开，向洗涤脱水桶22内进行供水。如图3的虚线箭头所示，来自水龙头的水被供给至第二水路613内并流过第二水路613内到达注水室611，从注水口611a放出至洗涤脱水桶22内。这时，流过第二水路613的水的流量多于流过第一水路612的水的流量。当洗涤脱水桶22内的水位达到规定的清洗水位时，关闭第一阀621和第二阀622，结束供水。
在基于柔顺剂投入按钮717的操作而设定了自动投入柔顺剂的情况下，在漂洗过程中的供水时，柔顺剂通过供水装置80被自动投入洗涤脱水桶22内。这时，与清洗过程一样，第一水路612成为与注水室611相连的状态。此外，第一三通阀630被切换为使第一入水口631与出水口633连通的状态，第一水路612成为在第一三通阀630的位置相连的状态。
首先，第二三通阀640被切换为使第二入水口642与出水口643连通的状态。由此，由柔顺剂供给管530实现的第一水路612与柔顺剂盒500之间的柔顺剂的导入路径成为打开状态。泵660工作，如图3的双点划线所示，柔顺剂盒500内的液体的柔顺剂经由柔顺剂供给管530被抽吸至第一水路612内。与 泵660的工作时间对应量的柔顺剂蓄于第一水路612内。
接着，第二三通阀640被切换为使第一入水口641与出水口643连通的状态。由此，由柔顺剂供给管530实现的第一水路612与柔顺剂盒500之间的柔顺剂的导入路径成为关闭状态。而且，第一水路612成为在第二三通阀640的位置相连的状态。如图3的实线箭头所示，第一阀621打开，来自水龙头的水被供给至第一水路612内。蓄于第一水路612内的柔顺剂被流过第一水路612内的水冲走而流向注水室611，从注水口611a投入洗涤脱水桶22内。
进而，与清洗过程一样，同时打开第二阀622和第一阀621，向洗涤脱水桶22内进行供水。
清洗过程和漂洗过程中的洗涤脱水桶22内的水位即水量根据供水前检测出的洗涤物的负荷量来决定。并且，投入洗涤脱水桶22内的液剂的量即液剂的使用量根据水量来决定。
例如，相对于基准水量(例如30升)的液剂的量与各种液剂的种类建立对应，预先存储于存储部802。用户通过规定的设定操作，从各种液剂的种类中选择并设定洗涤剂盒400和柔顺剂盒500中收容的液剂的种类。控制部801从存储部802读出设定种类的相对于基准水量的液剂的量，由读出的液剂的量和根据负荷量确定的水量，计算出与该水量相符的液剂的量，将计算出的液剂的量作为这次洗涤运转中的液剂的使用量。在通过洗涤剂投入按钮716和柔顺剂投入按钮717进行了“量多”或者“量少”的设定的情况下，将计算出的液剂的量增加或减少规定的比例来作为液剂的使用量。
在清洗过程的供水时，确定的使用量的洗涤剂通过泵660的工作而从洗涤剂盒400导入供水单元600的第一水路612。同样地，在漂洗过程的供水时，确定的使用量的柔顺剂通过泵660的工作而从柔顺剂盒500导入供水单元600的第一水路612。
需要说明的是，在未设定自动投入洗涤剂的情况下，清洗过程中的供水时不从洗涤剂盒400内向供水单元600导入洗涤剂和向第一水路612供给自来水，并且不向洗涤脱水桶22内自动投入洗涤剂。这种情况下，只通过供水单元600的第二水路613向洗涤脱水桶22的供水。洗涤剂被用户手动投入洗涤脱水桶22 内。同样地，在未设定自动投入柔顺剂的情况下，漂洗过程中的供水时不从柔顺剂盒500内向供水单元600导入柔顺剂和向第一水路612供给自来水，并且不向洗涤脱水桶22内自动投入柔顺剂。这种情况下，只通过供水单元600的第二水路613向洗涤脱水桶22的供水。柔顺剂被用户手动投入洗涤脱水桶22内。
全自动洗衣机1能进行由超声波清洗装置50实现的清洗运转。
在清洗运转时，从贮留箱60向贮水桶210供给清洗水之后，洗涤物的污垢附着部分被置于贮水桶210与超声波发生体110之间。污垢附着部分被蓄于贮水桶210内的清洗水浸泡，并且与超声波发生体110的前端面接触。当超声波发生体110工作时，从其前端产生超声波。通过超声波的作用，从被清洗物中剥离污垢。这时，通过加上洗涤剂的力，清洗力提高。
在清洗运转中的供水时，在向贮水桶210进行供水之前，通过供水装置80向贮留箱60内供给清洗水。这时，供给阀61关闭。
首先，第三三通阀650被切换为使入水口651与第二出水口653连通的状态。由此，第一水路612成为与注水室611隔断并经由分支水路616与贮留箱60相连的状态。与清洗过程一样，在第一三通阀630被切换为能使洗涤剂流入第一水路612的状态之后，泵660工作，洗涤剂盒400内的液体洗涤剂被抽吸至第一水路612内，蓄于第一水路612内。
接着，第一三通阀630被切换为使洗涤剂导入路径关闭并使第一水路612在第一三通阀630的位置相连的状态。然后，供水阀620的第一阀621打开，来自水龙头的水被供给至第一水路612内。蓄于第一水路612内的洗涤剂被流过第一水路612内的水冲走，洗涤剂与水混合成为清洗水。清洗水经过分支水路616流入贮留箱60内。当贮留箱60内蓄有规定量的清洗水时，第一阀621关闭。
打开供给阀61，贮留箱60内的清洗水经由供给喷嘴62被供给至贮水桶210内。然后，清洗运转中，每当贮水桶210内的清洗水由于被洗涤物吸水而减少时，相连量的清洗水会从贮留箱60补给向贮水桶210。
本实施方式的全自动洗衣机1具备在洗涤剂盒400内、柔顺剂盒500内的液剂的量变少时通知需要补充液剂的功能。用于该功能的处理即液剂补充告知 处理由控制部801执行。
图7的(a)是表示液剂补充告知处理的流程图。图7的(b)和(c)分别是示意性地表示洗涤剂盒400内的液位高于规定液位L1的情况和低于规定液位情况下的洗涤剂量检测部804输出的脉冲信号的图。
关于洗涤剂盒400内的洗涤剂和柔顺剂盒500内的柔顺剂，分别通过控制部801并行地执行液剂补充告知处理。执行液剂补充告知处理的时刻可以设定为例如完成洗涤运转的时刻、对全自动洗衣机1接通电源的时刻、进行用于确认洗涤剂、柔顺剂的剩余量的操作的时刻中的至少一者。需要说明的是，关于洗涤剂，可以在液剂补充告知处理于完成洗涤运转的时刻被执行的情况下，在清洗运转完成的时刻也执行液剂补充告知处理。
以下，对于告知液剂补充处理，以关于洗涤剂盒400内的洗涤剂的处理为例进行说明。
参照图7的(a)，控制部801在一对电极端子421、422之间进行规定时间例如2秒的通电(S101)。然后，控制部801检测通电期间从洗涤剂量检测部804输出的脉冲信号的脉冲宽度，根据检测出的脉冲宽度来判定洗涤剂盒400内的液位是否低于规定液位L1(S102)。
如图7的(b)所示，在洗涤剂盒400内的液位高于规定液位L1的情况下，一对电极端子421、422之间因介有洗涤剂而成为阻值为相对较低的状态，脉冲宽度相对变宽。另一方面，如图7的(c)所示，在洗涤剂盒400内的液位低于规定液位L1的情况下，一对电极端子421、422之间因介有空气而成为阻值相对较高的状态，脉冲宽度相对变窄。
洗涤剂盒400内的液位是否低于规定液位L1通过检测出的脉冲宽度是否大于根据用户设定的洗涤剂的种类而设定的阈值来判定。
在洗涤剂盒400内的液位低于规定液位L1的情况下(102：是)，控制部801对使用量的累计值XT加上最近的洗涤剂使用量X，求出新的使用量的累计值XT(S103)。例如在完成洗涤运转的时刻执行了液剂补充告知处理的情况下，最近的洗涤剂使用量X为本次洗涤运转中的使用量，在对全自动洗衣机1接通电源的时刻执行了液剂补充告知处理的情况下，最近的洗涤剂使用量X为上次 洗涤运转中的使用量。
接着，控制部801判定使用量的累计值XT是否大于阈值(S104)。这里，阈值例如被设定为在从洗涤剂盒400内的液位大致处于规定液位L1时的洗涤剂的量中减去阈值量时，一次洗涤运转量的洗涤剂会残留在洗涤剂盒400内这样的值。
在使用量的累计值XT为阈值以下的情况下(S104：否)，控制部801将使用量的累计值XT存储于存储部802(S106)。这时，使用量的累计值XT以即使切断全自动洗衣机1的电源也会被保存的方式存储于存储部802的EEPROM中。
在洗涤剂盒400内的液位低于规定液位L1的情况下，由于每次使用洗涤剂时都要加上洗涤剂使用量X，因此，使用量的累计值XT不断增加。由此，在使用量的累计值XT超过阈值的情况下(S104：是)，设为补充条件成立，控制部801使显示部720进行表示需要向洗涤剂盒400内补充洗涤剂的告知(S105)。例如，显示部720中，被分配给表示需要补充的告知的LED点亮或者闪烁。由显示部720实现的告知例如在经过规定时间时停止。
控制部801将超过阈值的使用量的累计值XT存储于存储部802(S106)。
S102中，在洗涤剂盒400内的液位不低于规定液位L1的情况下(S102：否)，控制部801将使用量的累计值XT设为零(S107)。即，在使用量的累计值XT不是零的情况下，复位为零，在使用量的累计值XT为零的情况下维持为零不变。需要说明的是，在比规定液位L1低的液位通过向洗涤剂盒400内补充洗涤剂而变为规定液位L1以上的情况下，使用量的累计值XT被复位为零。
控制部801将为零的使用量的累计值XT存储于存储部802(S106)。
这样，液剂补充告知处理结束。
对于柔顺剂盒500内的柔顺剂相关的控制处理，与洗涤剂盒400内的洗涤剂相关的控制处理相同。即，向一对电极端子521、522之间进行通电，根据其导通状态来判定柔顺剂盒500内的液位是否低于规定液位L2。然后，在液位低于规定液位L2的状态下，当柔顺剂的使用量的累计值XT超过阈值时，通过显示部720进行告知。例如，显示部720中，被分配给表示需要补充柔顺剂的告 知的LED点亮或者闪烁。
需要说明的是，在完成洗涤运转的时刻及对全自动洗衣机1接通电源的时刻和/或进行用于确认洗涤剂、柔顺剂的剩余量的操作的时刻执行液剂补充告知处理的情况下，在对全自动洗衣机1接通电源的时刻和/或进行用于确认洗涤剂、柔顺剂的剩余量的操作的时刻的液剂补充告知处理中，在图7的(a)的S102中判定为液位低于规定液位L1、L2的情况下，不执行S103的计算使用量的累计值XT的处理和S106的存储使用量的累计值XT的处理。
那么，本实施方式的全自动洗衣机1中，如上所述，在洗涤剂被自动投入洗涤脱水桶22时，通过第一三通阀630，第一水路612与洗涤剂盒400之间的洗涤剂导入路径在向第一水路612导入洗涤剂时被切换为打开状态，在向第一水路612供水时被切换为关闭状态。同样地，在柔顺剂被自动投入洗涤脱水桶22时，通过第二三通阀640，第一水路612与柔顺剂盒500之间的柔顺剂的导入路径在向第一水路612导入柔顺剂时被切换为打开状态，在向第一水路612供水时被切换为关闭状态。
这样的结构中，在因第一三通阀630、第二三通阀640发生异物堵塞等不良情况而导致导入路径无法完全关闭的情况下，供给至第一水路612的一部分水可能会进入洗涤剂盒400内、柔顺剂盒500内。当在像这样洗涤剂盒400内、柔顺剂盒500内进水的状态下继续供水时，存在从洗涤剂盒400的投入口401、柔顺剂盒500的投入口501溢水的隐患。
因此，本实施方式的全自动洗衣机1具备如下功能：在清洗过程中自动投入洗涤剂的供水和漂洗过程中自动投入柔顺剂的供水中，当洗涤剂盒400内、柔顺剂盒500内发生了进水时，中断供水并进行异常告知。
图8是表示自动投入液剂的供水时的控制处理的流程图。图9的(a)和(b)是示意性地表示在初始的供水前获取的脉冲信号的一例的图。图9的(c)和(d)是示意性地表示在正常时于初始的供水后获取的脉冲信号的一例的图，图9的(e)是示意性地表示在异常时于初始的供水后获取的脉冲信号的一例的图。
以下，以自动投入洗涤剂的清洗过程中的供水为例进行说明，而自动投入柔顺剂的漂洗过程中的供水也是一样的。
参照图8，控制部801在将第一三通阀630切换为使第二入水口632与出水口633连通的状态之后使泵660工作，将洗涤剂盒400内的洗涤剂导入第一水路612内(S201)。
接着，控制部801向一对电极端子421、422之间进行通电，获取从洗涤剂量检测部804输出的脉冲信号的脉冲宽度来作为初始洗涤剂脉冲宽度A(S202)。进而，控制部801向一对电极端子521、522之间进行通电，获取从柔顺剂量检测部805输出的脉冲信号的脉冲宽度来作为初始柔顺剂脉冲宽度B(S203)。需要说明的是，S202和S203中输出的脉冲信号相当于本发明的“第二检测信号”。
在洗涤剂盒400内的液位高于规定液位L1的情况下，一对电极端子421、422之间产生的阻值根据洗涤剂的浓度而变化。因此，如图9的(a)所示，初始洗涤剂脉冲宽度A取与洗涤剂盒400内的洗涤剂的浓度对应的值。同样地，在柔顺剂盒500内的液位高于规定液位L2的情况下，初始柔顺剂脉冲宽度B取与柔顺剂盒500内的柔顺剂的浓度对应的值。这里，洗涤剂的浓度表示存在于洗涤剂盒400内的液体中液剂的比例，柔顺剂的浓度表示存在于柔顺剂盒500内的液体中柔顺剂的比例。通常，洗涤剂盒400内只投入洗涤剂，柔顺剂盒500内只投入柔顺剂，因此，这些液剂的浓度为100％。需要说明的是，在洗涤剂、柔顺剂以预先被水稀释的方式投入的情况下，这些液剂的浓度为低于100％的值。
另一方面，在洗涤剂盒400内的液位低于规定液位L1的情况下，一对电极端子421、422之间介有空气而不介有洗涤剂。因此，如图9的(b)所示，初始洗涤剂脉冲宽度A取基于空气的介入的值。同样地，在柔顺剂盒500内的液位低于规定液位L2的情况下，初始柔顺剂脉冲宽度B取基于空气的介入的值。
接着，控制部801设定初始供水时间(S204)。即，控制部801在基于初始洗涤剂脉冲宽度A和初始柔顺剂脉冲宽度B判定为洗涤剂盒400内的液位和柔顺剂盒500内的液位双方分别为规定液位L1、L2以上的情况下设定第一时间作为初始供水时间，在任一液位低于规定液位L1、L2的情况下设定第二时间作为初始供水时间。例如，在以洗涤剂盒400内的液位远低于规定液位L1的状态进行了初始供水时间的供水时洗涤剂盒400内发生了进水的情况下，为了检测 到该情况，需要洗涤剂盒400内的液位因进入的水而成为规定液位L1以上从而使一对电极端子421、422之间介有含水的洗涤剂，需要较长时间的供水。因此，第二时间优选设定为比第一时间长的时间。例如，第一时间和第二时间被设为从十几秒到几十秒左右的时间，预先通过试验等来确定。
接着，控制部801在将第一三通阀630切换为使第一入水口631与出水口633连通的状态之后打开第一阀621，向第一水路612内进行初始供水时间的初始的供水(S205)。导入第一水路612内的洗涤剂被水冲走而被送向洗涤脱水桶22内。当经过初始供水时间时，第一阀621关闭，供水停止。
接着，控制部801向一对电极端子421、422之间进行通电，获取从洗涤剂量检测部804输出的脉冲信号的脉冲宽度来作为洗涤剂脉冲宽度M1(S207)。进而，控制部801向一对电极端子521、522之间进行通电，获取从柔顺剂量检测部805输出的脉冲信号的脉冲宽度来作为柔顺剂脉冲宽度M2(S208)。需要说明的是，S207和S208中输出的脉冲信号相当于本发明的“第一检测信号”。
接着，控制部801对洗涤剂脉冲宽度M1和初始洗涤剂脉冲宽度A进行比较，判定两者是否大致相等即判定两者之差是否处于考虑了检测误差等而设定的被视为相等的规定范围内，并且，对柔顺剂脉冲宽度M2和初始柔顺剂脉冲宽度B进行比较，判定两者是否大致相等(S209)。
在S205中的初始的供水时洗涤剂盒400内和柔顺剂盒500内没有进水的正常情况下，如图9的(c)和(d)所示，洗涤剂脉冲宽度M1和柔顺剂脉冲宽度M2分别与初始洗涤剂脉冲宽度A和初始柔顺剂脉冲宽度B大致相等。
因此，在洗涤剂脉冲宽度M1与初始洗涤剂脉冲宽度A大致相等且柔顺剂脉冲宽度M2与初始柔顺剂脉冲宽度B大致相等的情况下(S209：是)，控制部801打开第一阀621恢复向第一水路612内的供水，并且打开第二阀622而向第二水路613内进行供水(S210)。将残留于第一水路612内的洗涤剂送往洗涤脱水桶22，并且向洗涤脱水桶22内进行供水。在向洗涤脱水桶22内进行供水直到洗涤脱水桶22内的水位达到规定的清洗水位之后(S211：是)，控制部801关闭第一阀621和第二阀622。
另一方面，在S205中的初始的供水时发生了洗涤剂盒400内进水的异常的 情况下，成为一对电极端子421、422之间介有被进入的水稀释过的洗涤剂的状态，洗涤剂脉冲宽度M1取与稀释后的洗涤剂的浓度对应的值。同样地，在发生了柔顺剂盒500内进水的异常的情况下，成为一对电极端子521、522之间介有被进入的水稀释过的柔顺剂的状态，柔顺剂脉冲宽度M2取与稀释后的柔顺剂的浓度对应的值。因此，无论初始洗涤剂脉冲宽度A和初始柔顺剂脉冲宽度B是图9的(a)那样的液位高于规定液位L1、L2时的值和图9的(b)那样的液位低于规定液位L1、L2时的值中的哪一个，洗涤剂脉冲宽度M1和柔顺剂脉冲宽度M2都分别如图9的(e)所示与初始洗涤剂脉冲宽度A和初始柔顺剂脉冲宽度B大不相同。
因此，在洗涤剂脉冲宽度M1与初始洗涤剂脉冲宽度A不大致相等、柔顺剂脉冲宽度M2与初始柔顺剂脉冲宽度B不大致相等的情况下(S209：否)，控制部801判定为洗涤剂盒400内或柔顺剂盒500内有可能发生了进水，作为异常处理，不恢复向第一水路612内的供水，并且不向第二水路613内进行供水，使显示部720进行表示洗涤剂盒400、柔顺剂盒500可能发生了进水的异常告知(S212)。例如，显示部720中，在视为洗涤剂盒400内发生了进水的情况下，与洗涤剂盒400中的异常对应的LED闪烁或者点亮，在视为柔顺剂盒500内发生了进水的情况下，与柔顺剂盒500中的异常对应的LED闪烁或者点亮。
＜实施方式的效果＞
以上，根据本实施方式，具备输出脉冲宽度根据洗涤剂盒400内的洗涤剂的浓度而变化的脉冲信号的洗涤剂量检测部804和检测脉冲宽度根据柔顺剂盒500内的柔顺剂的浓度而变化的脉冲信号的柔顺剂量检测部805，在根据开始向第一水路612供水后从洗涤剂量检测部804输出的脉冲信号的洗涤剂脉冲宽度M1和从柔顺剂量检测部805输出的脉冲信号的柔顺剂脉冲宽度M2，判定为洗涤剂盒400内和柔顺剂盒500内可能发生了进水的情况下，进行异常处理。由此，能防止洗涤剂盒400内和柔顺剂盒500内进水的异常状态被置之不顾。
此外，根据本实施方式，基于洗涤剂脉冲宽度M1和柔顺剂脉冲宽度M2与开始向第一水路612供水之前从洗涤剂量检测部804输出的脉冲信号的初始洗涤剂脉冲宽度A和从柔顺剂量检测部805输出的脉冲信号的初始柔顺剂脉冲宽度B的比较结果，判定洗涤剂盒400内和柔顺剂盒500内有无进水。根据该结 构，以基于供水前的洗涤剂盒400内的实际的洗涤剂的浓度的脉冲信号和基于供水前的柔顺剂盒500内的实际的柔顺剂的浓度的脉冲信号为比较的基准，因此，不容易受投入洗涤剂盒400内和柔顺剂盒500内的洗涤剂和柔顺剂的种类、投入时的浓度影响，能精确地判定有无进水。
进而，根据本实施方式，中止对第一水路612供水来作为异常处理，因此，能防止从洗涤剂盒400内和柔顺剂盒500内因初始的供水而进水的状态进一步进水，能抑制从洗涤剂盒400和柔顺剂盒500溢水。
进而，根据本实施方式，通过显示部720进行异常告知来作为异常处理，因此，能向用户通知洗涤剂盒400内和柔顺剂盒500内可能发生了进水，能谋求从第一三通阀630、第二三通阀640去除异物等异常的消除。
进而，根据本实施方式，在开始向第一水路612供水起经过初始供水时间时停止供水，从洗涤剂量检测部804和柔顺剂量检测部805获取脉冲信号，因此，能避免在处于洗涤剂盒400内和柔顺剂盒500内进水的状态的情况下在获取脉冲信号进行判定的期间继续进水。
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，上述实施方式中，根据开始向第一水路612供水之后获取的洗涤剂脉冲宽度M1和柔顺剂脉冲宽度M2与开始向第一水路612供水之前获取的初始洗涤剂脉冲宽度A和初始柔顺剂脉冲宽度B的比较结果来判定洗涤剂盒400内和柔顺剂盒500内有无进水。但是，也可以根据洗涤剂脉冲宽度M1和柔顺剂脉冲宽度M2与作为阈值预先准备的脉冲信号的脉冲宽度的比较结果来判定有无进水。
此外，上述实施方式中，在从开始向第一水路612供水起经过初始供水时间时停止供水，从洗涤剂量检测部804和柔顺剂量检测部805获取脉冲信号。但是，也可以采用在继续供水的状态下获取脉冲信号的结构。这种情况下，当判定为洗涤剂盒400内和柔顺剂盒500内发生了进水时，停止供水。
进而，上述实施方式中，为了在打开状态与关闭状态之间切换第一水路612与洗涤剂盒400之间的洗涤剂导入路径而使用了第一三通阀630，为了在打开状 态和关闭状态之间切换第一水路612与柔顺剂盒500之间的柔顺剂的导入路径而使用了第二三通阀640。但是，导入路径的开闭也可以通过电磁阀等开闭阀来进行。
进而，上述实施方式中，供水装置80采用包括洗涤剂盒400和柔顺剂盒500并能将洗涤剂和柔顺剂双方自动投入洗涤脱水桶22内的结构。但是，供水装置80也可以采用不包括洗涤剂盒400和柔顺剂盒500中的任一者的结构。在采用没有柔顺剂盒500的结构的情况下，图8的供水控制处理只在清洗过程中执行，没有S203和S208的处理，在S209中，只判定洗涤剂脉冲宽度M1是否与初始洗涤剂脉冲宽度A大致相等。同样地，在采用没有洗涤剂盒400的结构的情况下，图8的供水控制处理只在漂洗过程中执行，没有S202和S207的处理，在S209中，只判定柔顺剂脉冲宽度M2是否与初始柔顺剂脉冲宽度B大致相等。
进而，上述实施方式中，洗涤剂量检测部804采用输出高电压的脉冲宽度根据一对电极端子421、422之间产生的阻值而变化的脉冲信号的电路结构，但是也可以采用输出大小不同的电压信号等与脉冲信号不同的检测信号的电路结构。同样地，柔顺剂量检测部805也可以采用输出与脉冲信号不同的检测信号的电路结构。
进而，上述实施方式中，通过显示部720进行异常告知。但是，也可以由设置于全自动洗衣机1的未图示的扬声器来进行由声音等响声实现的异常告知。
进而，一对电极端子421、422、521、522的形状、在洗涤剂盒400内和柔顺剂盒500内的配置不局限于上述实施方式，可以是任何形状、配置。
进而，上述实施方式中，也可以在向贮留箱60供给清洗水时进行与图8的供水控制处理相同的供水控制处理。
进而，上述实施方式中，全自动洗衣机1中设置有超声波清洗装置50，为了向超声波清洗装置50供水而设置有供给喷嘴62和贮留箱60。但是，全自动洗衣机1也可以采用不设置超声波清洗装置50、供给喷嘴62以及贮留箱60的结构。这种情况下，供水装置80中不设置第三三通阀650和分支水路616。
进而，上述实施方式中，示出了全自动洗衣机1。但是，本发明也能应用于全自动洗衣机1之外的洗衣机，例如具有横轴型滚筒来作为洗涤桶的滚筒式洗 衣机。此外，本发明也能应用于具有烘干功能的全自动洗干一体机和滚筒式洗干一体机。
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形。
