发明内容
发明所要解决的问题
本发明是在这样的背景下完成的发明,其目的在于提供一种洗干一体机,其能实现部件数量的减少。
用于解决问题的方案
本发明是一种洗干一体机,包括:水筒,可蓄水;洗涤筒,收容于所述水筒内,收容洗涤物并进行旋转;循环路,具有与所述水筒连接的取出口和返回口;送风部,将所述水筒内的空气从所述取出口取出至所述循环路内,从所述返回口返回至所述水筒内,由此使所述水筒内的空气循环;加热部,设置于所述循环路内,加热所述循环路内的空气;以及水过滤器,具有构成所述循环路中的比所述加热部更靠所述取出口侧的上游部分的容器,所述容器可蓄水,所述水过滤器使在所述循环路内从所述取出口前往所述返回口的空气穿过所述容器内的水,由此从该空气中捕获异物并对该空气除湿。
此外,本发明的特征在于,所述洗干一体机还包括:注水路,向所述容器内供水;供水阀,打开/关闭所述注水路;以及控制部,使所述送风部和所述加热部工作来执行烘干运转或打开/关闭所述供水阀,在烘干运转中打开所述供水阀。
此外,本发明的特征在于,所述控制部在烘干运转中每隔规定时间打开所述供水阀。
此外,本发明的特征在于,在所述容器,形成有用于使所述容器内的规定水位以上的水溢出到所述容器外的溢水口,所述洗干一体机还包括:排水路,从所述水筒内排水;导水路,与所述容器连接,将所述容器内的水导向所述排水路;排水阀,通过所述控制部的控制,打开/关闭所述导水路;以及溢水路,与所述溢水口和所述导水路连接,将从所述溢水口溢出的水导向所述导水路,所述控制部在烘干运转中每隔所述规定时间打开所述供水阀时,使所述排水阀保持关闭状态。
此外,本发明的特征在于,所述容器配置于所述循环路的所述上游部分中比所述加热部更靠近所述取出口的位置。
发明效果
根据本发明,洗干一体机的烘干运转中,水筒内的空气以从取出口被取出至循环路内并从返回口返回至水筒内的方式循环。循环的空气通过在循环路内被加热部加热而变成热风,将洗涤筒内的洗涤物烘干。具有构成循环路中的比 加热部更靠取出口侧的上游部分的容器的水过滤器使为了循环而在循环路内从取出口前往返回口的空气穿过蓄于容器内的水,由此从该空气中捕获异物。由此,能防止异物到达加热部而使加热部的性能降低。
在烘干运转中喷淋到洗涤筒内的洗涤物上的空气由于吸收洗涤物的水分而成为潮湿空气,从取出口被取出至循环路内。水过滤器使在循环路内从取出口前往返回口的潮湿空气穿过容器内的水与容器内的水进行热交换,从而进行除湿,因此,能将除湿后的空气再利用于洗涤筒内的洗涤物的烘干。
也就是说,通过水过滤器,不仅能捕获烘干运转中产生的异物,还能将潮湿空气除湿。由此,能实现部件数量的削减。
此外,根据本发明,执行烘干运转的控制部打开供水阀,使得水从注水路被供给并蓄于容器内,由此水过滤器的功能有效,因此,在烘干运转中,水过滤器捕获异物或将循环路内的空气除湿。当容器内的水温由于与潮湿空气的热交换而上升时,水过滤器的除湿性能降低。因此,控制部在烘干运转中打开供水阀将水供给至容器内,由此抑制容器内的水温的上升,因而能抑制水过滤器的除湿性能的降低。
此外,根据本发明,控制部在烘干运转中每隔规定时间打开供水阀而将水供给至容器内,由此定期地抑制容器内的水温的上升,因而能持续地抑制水过滤器的除湿性能的降低。
此外,根据本发明,控制部打开排水阀,由此蓄于容器内的异物与水一起通过导水路排出到排水路。因此,使用者可以不进行接触水过滤器来去除容器内的异物的维护。因此,能实现对烘干运转的使用便利性的提高。当容器内的水位上升至规定水位时,规定水位以上的水从溢水口溢出到溢水路并通过导水路排出到排水路。因此,能防止从容器内溢出的水洒到洗干一体机内而弄湿电气部件等。
控制部在为了抑制容器内的水温的上升而在烘干运转中每隔规定时间打开供水阀时,使排水阀保持关闭状态。由此,控制部打开供水阀而向容器内供水,这时,通过使多余的水从溢水口溢出到溢水路,能向容器内供给抑制容器内的水温上升所需量的水。
此外,根据本发明,由于容器配置于循环路的上游部分中比加热部更靠近取出口的位置,因而水过滤器能从由取出口刚被取出至循环路的空气中迅速地捕获异物。由此,能缩小循环路中含有异物的空气所蔓延的区域,因而能防止异物附着在循环路的大部分位置。

具体实施方式
以下,参照附图,对本发明的实施方式进行具体说明。图1是本发明的一实施方式的洗干一体机1的示意性纵剖右视图。将与图1的纸面垂直的方向称为洗干一体机1的左右方向X,将图1中的左右方向称为洗干一体机1的前后方向Y,将图1中的上下方向称为洗干一体机1的上下方向Z。左右方向X当中,将图1的纸面的里侧称为左侧X1,将图1的纸面的表侧称为右侧X2。前后方向Y当中,将图1中的左侧称为前侧Y1,将图1中的右侧称为后侧Y2。上下方向Z当中,将上侧称为上侧Z1,将下侧称为下侧Z2。洗干一体机1为所谓的滚筒式洗干一体机,执行清洗运转、漂洗运转、脱水运转以及烘干运转。洗干一体机1包括:箱体2、配置于箱体2内的水筒3、与水筒3连接的供水路4和排水路5、从流过排水路5的水中捕获异物的排水过滤器6、收容于水筒3内的洗涤筒7、使洗涤筒7旋转的马达8以及将洗涤筒7内的洗涤物L烘干的烘干单元9。

排水路5与水筒3的下端部,例如正面壁3C的第一正面部3E的下端部连接。水筒3内的水从排水路5排出至机外。在排水路5中的与水筒3连接的端部,设置有例如由蛇纹软管构成的弹性变形部5A,因此能抑制水筒3的振动传递到整个排水路5。在排水路5的中途,设置有为了开始或停止排水而被打开/关闭的主排水阀13。
排水过滤器6设置于排水路5中的比主排水阀13更靠近水筒3的上游部。排水过滤器6的前端露出到箱体2的前表面2A,因此,使用者能抓住排水过滤 器6的前端将排水过滤器6拆装于箱体2。排水过滤器6的结构能使用公知的结构。
洗涤筒7比水筒3小一圈,内部能收容洗涤物L。洗涤筒7具有与水筒3的圆周壁3A同轴状地配置的圆筒状的圆周壁7A、从后侧Y2堵住圆周壁7A的中空部分的圆盘状的背面壁7B以及从圆周壁7A的前端缘向轴线J侧突出的圆环状的环状壁7C。在洗涤筒7,至少在圆周壁7A形成有多个贯通孔7D,水筒3内的水经由贯通孔7D在水筒3与洗涤筒7之间往来。由此,水筒3内的水位与洗涤筒7内的水位一致。在洗涤筒7的背面壁7B的中心,设置有沿轴线J向后侧Y2延伸的支承轴14。支承轴14的后端部穿过水筒3的背面壁3B的贯通孔3D而配置于背面壁3B的后侧Y2。
在环状壁7C的内侧,形成有从前侧Y1与圆周壁7A的中空部分连通的出入口7E。出入口7E处于从后侧Y2与水筒3的出入口3H和箱体2的开口2B对置并连通的状态。出入口3H和7E与开口2B一起通过门10被一并打开/关闭。洗干一体机1的使用者经由敞开的开口2B、出入口3H以及7E,向洗涤筒7内投取洗涤物L。
马达8在箱体2内配置于水筒3的背面壁3B的后侧Y2。马达8与设置于洗涤筒7的支承轴14连结。马达8所产生的驱动力传递至支持轴14,洗涤筒7随着支承轴14绕轴线J旋转。需要说明的是,可以在马达8与支承轴14之间设置将马达8的驱动力向支承轴14传递或切断的离合器机构(未图示)。
烘干单元9包括与水筒3连接的循环路20、使循环路20内产生空气流的送风部21以及在循环路20内加热空气的加热部22。循环路20是在箱体2内配置于水筒3的上侧Z1的流路。循环路20固定于箱体2,具有沿前后方向Y延伸的中途部分20A、从中途部20A的后端向下侧Z2延伸的后部分20B以及从中途部20A的前端向下侧Z2延伸的前部分20C。在后部分20B的下端部形成有取出口20D。取出口20D处于与水筒3中的例如背面壁3B连接并从后侧Y2与水筒3内连通的状态。在前部分20C的下端部形成有返回口20E。返回口20E处于与水筒3中的例如正面壁3C的第二正面部3F的上端部连接并从上侧Z1与水筒3内连通的状态。在循环路20中的与水筒3连接的两端部,设置有例如由蛇纹软管构成的弹性变形部20F,因此,能抑制水筒3的振动传递到整个循环路 20。
送风部21是所谓的鼓风机,包括在循环路20的内部配置于靠近取出口20D的区域的旋转叶片23和使旋转叶片23旋转的马达(未图示)。烘干运转中,通过旋转叶片23旋转,水筒3内和洗涤筒7内的空气如粗虚线箭头所示,在从取出口20D被取出至循环路20内之后,从返回口20E返回至水筒3内。由此,水筒3内的空气以按顺序流过水筒3和循环路20的方式循环。
加热部22是热泵中的热交换器或普通的加热器等,至少一部分设置于循环路20内。加热部22中的设置于循环路20内的部分具有多个翅片状的放热部22A。烘干运转中,加热部22工作而使得放热部22A变得高温,因此,流过循环路20内的空气在经过放热部22A的周围时会被加热而变成热风。烘干运转中,会产生线头、灰尘等异物,该异物随热风流动。当异物附着并蓄积于加热部22的放热部22A时,可能会随着加热部22中的加热效率降低、循环路20中的空气流动变差而导致性能降低,因此,需要将这些异物捕获。
烘干单元9包括通过水将流过循环路20内的空气中所含的异物捕获的水过滤器30、向水过滤器30供水的注水路31以及打开/关闭注水路31的供水阀32。烘干单元9还包括将水过滤器30内的水引导向排水路5的导水路33、打开/关闭导水路33的排水阀34以及使水过滤器30内的溢水向导水路33的溢水路35。以下,在对构成烘干单元9的循环路20进行详细说明之后,对水过滤器30、注水路31、供水阀32、导水路33、排水阀34以及溢水路35进行说明。
将循环路20中的比加热部22的放热部22A更靠取出口20D侧的部分称为上游部分20G。上游部分20G由中途部分20A的一部分和整个后部分20B构成。需要说明的是,在送风部21的旋转叶片23配置于比放热部22A更靠取出口20D侧的情况下,可以将循环路20中的比旋转叶片23更靠取出口20D侧的部分看作是上游部分20G。后部分20B包括从取出口20D向水平方向H延伸并向下侧Z2折曲的第一部20BA和从中途部分20A的后端向下侧Z2延伸的第二部20BB。在第一部20BA设置有弹性变形部20F。
洗干一体机1内的水过滤器30的上下方向的姿态是固定的,但是水过滤器30的左右方向和前后方向的姿态能根据洗干一体机1内的水过滤器30的配置空间来任意改变。以下,为了方便,将图2看作是水过滤器30的左视图,使用左 右方向X、前后方向Y以及上下方向Z来限定水过滤器30。因此,与图2的纸面垂直的方向为水过滤器30的左右方向X,图2中的左右方向为水过滤器30的前后方向Y,图2中的上下方向为水过滤器30的上下方向Z。此外,与图2相对应,图3是水过滤器30的主视图,图4是从右侧X2观察水过滤器30的立体图。
水过滤器30具有例如树脂制的箱状的容器40。容器40具有:在左右方向X上较长的椭圆板状的底壁41、将底壁41的外缘包边并从底壁41向上侧Z1立起的在左右方向X上较长的椭圆筒状的下侧壁42以及具有在左右方向X上较长的长方形轮郭并在仰视观察时从下侧壁42的上端的外缘突出的横壁43。容器40还具有将横壁43的外缘包边并向上侧Z1立起的在左右方向X上较长的角筒状的上侧壁44和沿水平方向H延伸并与上侧壁44的上端连接的顶壁45。横壁43相对于水平方向H倾斜,与此对应,下侧壁42的上端和上侧壁44的下端也相对于水平方向H倾斜。下侧壁42、横壁43以及上侧壁44构成容器40的整个侧壁46。侧壁46具有筒状的整体形状,从横向也就是前后左右包围容器40的内部空间40A。
图5是图2的A-A剖视图。底壁41形成为随着临近左侧X1而下降的板状,从下侧Z2堵住容器40的内部空间40A。在底壁41的左端部形成有向下侧Z2延伸并垂直地贯通底壁41的排水口41A。底壁41的上表面部41B的整个区域以越是临近排水口41A越是下降的方式倾斜(也参照图3的B-B线处的阶梯剖视图即图7)。排水口41A位于内部空间40A的下端。在底壁41设置有将排水口41A包边并且向下侧Z2突出的筒状的连结部41C。在底壁41一体地设置有从底壁41的左端向上侧Z1延伸的纵长箱状的溢水部41D。在溢水部41D的左壁,沿上下方向Z排列设置有向左侧X1突出的两个管部41E。下侧Z2的管部41E的内部空间是与溢水部41D的内部空间连通的溢水口41F。
图6是包括图2的A-A剖面的立体图。下侧壁42与底壁41一体化,包围容器40的内部空间40A的下区域。下侧壁42中的与底壁41连结的连结部42A弯曲成圆弧状(也参照图7)。在下侧壁42的左壁的下端,形成有与溢水部41D的内部空间连通的连通口42B。下侧壁42中,左壁与后壁的连结部、后壁与右壁的连结部、右壁与前壁(未图示)的连结部以及前壁与左壁的连结部 分别弯曲成圆弧状。因此,在下侧壁42的内表面部42C中的相当于这些连结部的部分,设置有俯视观察时弯曲成圆弧状的弯曲部42D。在下侧壁42中的后壁与右壁的连结部处的弯曲部42D,设置有贯通下侧壁42的圆形状的供水口42E。供水口42E沿着弯曲部42D的弯曲横向设置,具体而言大致水平地朝向前侧Y1开口。在下侧壁42设置有从供水口42E向下侧壁42的外部突出的管状的连结部42F(参照图4)。连结部42F沿着下侧壁42中的弯曲的连结部42A的外周面的切线方向大致水平地延伸。
横壁43形成为将下侧壁42的上端包边的环状,与下侧壁42一体化。上侧壁44包围容器40的内部空间40A的上区域。在上侧壁44设置有将其下端包边的环状的引导部44A。引导部44A比横壁43的内缘更向容器40的内部空间40A突出。引导部44A设置于高于供水口42E的位置。上侧壁44的左壁和下侧壁42的左壁一起与底壁41的溢水部41D连结,从右侧X2堵住溢水部41D的内部空间。顶壁45从上侧Z1堵住容器40的内部空间40A。在顶壁45的右端部形成有在上下方向Z上贯通顶壁45的插通孔45A,在顶壁45的左端部形成有在上下方向Z上贯通顶壁45的出口45B。在顶壁45设置有将插通孔45A包边并且向上侧Z1突出的筒状的连结部45C,并设置有将出口45B包边并且向上侧Z1突出的筒状的连结部45D。水过滤器30的容器40由底壁41、溢水部41D、下侧壁42和横壁43、上侧壁44以及顶壁45组合而成。
容器40还包括配置于容器40的内部空间40A的上区域的下挡板47和上挡板48以及遍及内部空间40A的上区域和下区域地设置的纵管49。下挡板47形成为与横壁43平行地从上侧壁44的右壁的下端部向左下侧倾斜延伸的长方形状。在下挡板47的下表面部设置有单个或多个向下侧Z2突出并沿前后方向Y延伸的肋47A。上挡板48形成为从上侧壁44的左壁的上端部向右下侧倾斜延伸的长方形状。上挡板48的右端部配置于下挡板47的左端部的上侧Z1。在上挡板48的下表面部设置有单个或多个向下侧Z2突出并沿前后方向Y延伸的肋48A。纵管49插通于顶壁45的连结部45C和插通孔45A,穿过上挡板48的右侧X2,在上下方向Z上贯通下挡板47的右部分。纵管49的下端被配置为向上侧Z1稍微远离底壁41的上表面部41B的右部分。在纵管49形成有将其下端部切成正面观察时呈倒L字状的入口49A。下挡板47与纵管49一体化。形成于 下侧壁42的供水口42E配置于纵管49的右侧X2,与入口49A邻接。供水口42E配置于比顶壁45的出口45B更靠近入口49A的位置。
参照图1,水过滤器30在箱体2内配置于水筒3的背面壁3B的周边的后区域2C的下部,固定于箱体2。循环路20中的构成上游部分20G的后部分20B中,第一部20BA的下端部从上侧Z1与水过滤器30的容器40的顶壁45的连结部45C连结,第一部20BA的内部空间与容器40的纵管49的内部空间和入口49A连通。后部分20B中,第二部20BB的下端部从上侧Z1与容器40的顶壁45的连结部45D连结,第二部20BB的内部空间与容器40的出口45B连通。由此,容器40的内部空间40A位于第一部20BA的内部空间与第二部20BB的内部空间之间,与这些内部空间连通,容器40构成循环路20的上游部分20G的一部分。容器40配置于上游部分20G中的比加热部22更靠近循环路20的取出口20D的位置。
注水路31从供水路4中的比主供水阀12更靠水龙头侧的部分分支,与容器40的下侧壁42的连结部42F(参照图4)连结。注水路31的内部空间与下侧壁42的供水口42E连通。供水阀32设置于注水路31的中途,打开/关闭注水路31。
导水路33中的构成水过滤器30侧的端部的第一部分33A从下侧Z2与容器40的底壁41的连结部41C连结,导水路33的内部空间与底壁41的排水口41A连通。排水口41A向下侧Z2延伸,与第一部分33A的上端连接。导水路33中的构成与第一部分33A相反侧的端部的第二部分33B与排水路5中的比排水过滤器6更靠水筒3侧的上游部分连接。第二部分33B也可以直接与排水过滤器6连接。在第一部分33A和第二部分33B,分别设置有由例如蛇纹软管构成的弹性变形部33C,因此,第一部分33A和第二部分33B能弹性变形。导水路33中的第一部分33A与第二部分33B之间的第三部分33D例如经由支架50固定于水筒3。第三部分33D也可以直接固定于水筒3。导水路33中,构成其一部分的第一部分33A和第二部分33B能弹性变形,因此,能防止水筒3的振动从第三部分33D传递到水过滤器30的容器40、排水路5、排水过滤器6。第三部分33D也可以不固定于水筒3。
图8是水过滤器30及其周边部分的立体图。排水阀34设置于导水路33的 第一部分33A,打开/关闭导水路33。排水阀34包括配置于第一部分33A内的为了打开/关闭导水路33而进行移动的阀体(未图示)和使阀体移动的转矩马达等电动致动器34A。需要说明的是,主供水阀12、主排水阀13以及供水阀32既可以采用与排水阀34相同的结构,也可以由电磁阀等公知的阀构成。溢水路35与底壁41的溢水部41D中的下侧Z2的管部41E的溢水口41F和第一部分33A连接。
图9是表示洗干一体机1的电气结构的框图。洗干一体机1还包括控制部60和水位传感器61。控制部60例如配置成包括CPU62、存储后述的各种计数值/阈值等的ROM/RAM等存储器63以及计时用的计时器64的微型计算机,内置于箱体2内(也参照图1)。马达8、显示操作部11、主供水阀12、主排水阀13、送风部21、加热部22、供水阀32以及排水阀34分别与控制部60电连接。
控制部60控制马达8的旋转而使马达8产生驱动力或停止马达8的旋转。当使用者操作显示操作部11来选择洗涤物Q的运转条件等时,控制部60接受该选择。控制部60控制显示操作部11的显示。控制部60控制主供水阀12和主排水阀13的打开/关闭。当控制部60在关闭主排水阀13的状态下打开主供水阀12时,向水筒3供水来进行蓄水。当控制部60打开主排水阀13时,水筒3排水。控制部60使送风部21工作而产生风,使风在洗涤筒7与循环路20之间循环。控制部60使加热部22工作,将在洗涤筒7与循环路20之间循环的风变成热风。控制部60控制与水过滤器30相关的供水阀32和排水阀34各自的打开/关闭。水位传感器61是检测水过滤器30的容器40内的水位的公知的传感器,装配于容器40的溢水部41D的两根管部41E中的上侧Z1的管部41E(参照图8)。水位传感器61的检测结果被实时地输入控制部60。
图10是表示洗干一体机1中进行的处理的流程图。控制部60通过使马达8工作而分别打开/关闭主供水阀12和主排水阀13,由此按顺序执行清洗运转(步骤S1)、漂洗运转(步骤S2)以及脱水运转(步骤S3)。漂洗运转可以执行多次,脱水运转可以在清洗运转与漂洗运转之间、漂洗运转与下一次漂洗运转之间执行。脱水运转后,控制部60使送风部21和加热部22工作,分别打开/关闭主供水阀12、主排水阀13、供水阀32以及排水阀34,由此执行烘干运转 (步骤S4)。洗干一体机1中,也可以不经过清洗运转、漂洗运转以及脱水运转而只执行烘干运转。
在清洗运转开始之前,向洗涤筒7内投入洗涤剂。在清洗运转中,控制部60在关闭主排水阀13的状态下,将主供水阀12打开规定时间从而向水筒3和洗涤筒7供水,之后通过马达8使洗涤筒7旋转。由此,洗涤筒7内的洗涤物L被摔洗。摔洗中,洗涤物L被反复进行提升一定程度之后向水面自然落下的“摔打”。通过摔打所产生的冲击、蓄于洗涤筒7的洗涤剂水中所含的洗涤剂成分,从洗涤物L中去除污垢。从摔打开始经过规定时间之后,当控制部60打开主排水阀13进行排水时,清洗运转结束。
漂洗运转中,控制部60将主供水阀12打开规定时间从而向水筒3和洗涤筒7供水,之后通过马达8使洗涤筒7旋转。这样,由于上述的摔打反复进行,因而洗涤物L通过洗涤筒7内的自来水被漂洗。从摔打开始经过规定时间之后,当控制部60进行排水时,漂洗运转结束。脱水运转中,控制部60在打开主排水阀13的状态下使洗涤筒7脱水旋转。洗涤筒7内的洗涤物L通过由洗涤筒7的脱水旋转而产生的离心力被脱水。通过脱水而从洗涤物L渗出的水从排水路5排出至机外。
图11是表示烘干运转的流程图。烘干运转开始时,控制部60使加热部22工作而对加热部22的放热部22A进行预热(步骤S11),在关闭排水阀34的状态下打开供水阀32(步骤S12)。由此,来自水龙头的水穿过供水路4和注水路31,从水过滤器30的容器40的供水口42E被供给并蓄至容器40内。这时,控制部60停止送风部21以使容器40内的水不飞溅。也就是说,为了开始烘干运转,控制部60在送风部21工作之前打开供水阀32而向容器40内蓄水。此外,即使从供水口42E供给至容器40内的水向上侧Z1溅起,容器40内的引导部44A(参照图6)也能将这些水向下侧Z2引导。当水位传感器61所检测出的容器40内的水位上升至堵住纵管49的下端的入口49A的一部分的基准水位W(参照图5)时,水过滤器30的功能生效,因此,控制部60关闭供水阀32而结束向水过滤器30的供水。控制部60可以根据水位传感器61的检测结果来判断容器40内的水位是否上升至基准水位W,也可以不使用水位传感器61而根据是否经过所需时间来判断。该所需时间是容器40内的水位从容器40空的状 态到上升至基准水位W为止所需的时间,通过实验等预先确定并存储于存储器63。需要说明的是,向水过滤器30的供水也可以在洗涤运转之前执行。但是,在水过滤器30内的水可能会由于脱水运转所产生的振动而溢出来的情况下,优选在脱水运转之后向水过滤器30进行供水。
基准水位W设定于低于溢水口41F的位置(参照图5)。基准水位W被设置了下限和上限,可以将在这些下限与上限之间变化的水位看作是基准水位W。当容器40内的水位上升至与溢水口41F一致的规定水位时,容器40内的该规定水位以上的水穿过溢水口41F,溢出到容器40的外部的溢水路35,通过溢水路35被引导向导水路33,穿过导水路33和排水路5被排出到机外(参照图1)。因此,能防止从容器40内溢出来的水散落在洗干一体机1内,将控制部60等电气构件浸湿。容器40内的水位中设定有低于该规定水位且高于基准水位W的最大水位。最大水位设定于溢水口41F的下端的稍微下侧Z2。
在向水过滤器30供水后,控制部60在继续使加热部22工作的状态下使送风部21工作,由此执行主烘干处理(步骤S13)。由此,如上所述,产生被加热的空气,使其以依次流过水筒3和循环路20的方式循环。这些空气被吹到洗涤筒7内的洗涤物L上,吸收洗涤物L的水分。由此,烘干洗涤物L。吸收了洗涤物L的水分的空气变成潮湿的空气,如图1的粗虚线箭头所示,从取出口20D被取出至循环路20内并流向返回口20E。
在主烘干处理中刚刚从取出口20D流入循环路20内的空气穿过后部分的20B的第一部20BA,在水过滤器30的纵管49内下降。在纵管49内下降的空气如图5的粗虚线箭头所示,从纵管49的下端的入口49A流入水过滤器30的容器40内。如上所述,入口49A形成为倒L字状,因此,从入口49A流入容器40内的空气穿过蓄于容器40内的水并下降,在容器40的底壁41的跟前一边向右侧X2改变朝向一边在水中上升。这时,这些空气与容器40内的水进行热交换,由此进行除湿。进而,这些空气中所含的异物(参照图5的异物V)被容器40内的水捕获并与水一起蓄于容器40内。由此,能防止异物到达加热部22而降低加热部22的性能。也就是说,通过水过滤器30的水,不仅能捕获烘干运转中产生的异物,还能将潮湿空气除湿。由此,能实现部件数的削减、节水。此外,由于容器40配置在循环路20的上游部分20G中的比加热部22更 靠近取出口20D的位置,因此水过滤器30能从刚从取出口20D取出至循环路20的空气中迅速捕获异物(参照图1)。由此,能缩小循环路20中含有异物的空气所蔓延的区域,因此,能防止异物附着于循环路20的大部分。进而,由于容器40远离加热部22地配置,因此即使在容器40内由于随着空气与水的热交换而来的水温上升而产生热气,这些热气也很难到达加热部22。
这样去除了水分和异物的空气穿过容器40内的水面,进一步上升,在容器40的内部空间40A的下区域沿着下挡板47流向左侧X1。残留在这些空气中的异物在通过下挡板47的下表面部的肋47A时,从空气中分离而落到容器40内的水中。越过下挡板47的左端的空气上升,在内部空间40A的上区域沿上挡板48流向右侧X2。残留在这些空气中的异物在通过上挡板48的下表面部的肋48A时,从空气中分离而落到容器40内的水中。越过上挡板48的右端的空气一边向左侧X1改变方向一边上升而到达顶壁45的出口45B,穿过出口45B从容器40内向后部分的20B的第二部20BB流出,朝向返回口20E在第二部20BB内上升。
在第二部20BB内上升的空气如图1的粗虚线箭头所示,穿过送风部21的旋转叶片23,在循环路20的中途部分20A内流向前侧Y1,并在此时通过穿过加热部22的放热部22A而被再次加热。被再次加热的空气在循环路20的前部分20C内下降,前往返回口20E,从返回口20E被供给至水筒3内和洗涤筒7内,被再次利用来烘干洗涤筒7内的洗涤物L。
参照图11,当将步骤S13的主烘干处理例如持续2~3小时左右的规定时间时,控制部60停止加热部22(步骤S14)。这种状态下,送风部21还在继续工作中,因此,冷风循环而被吹到洗涤筒7内的洗涤物L上,由此洗涤物L被降温。然后,当控制部60使冷风的循环持续几十分钟左右的规定时间时,作为烘干运转结束时的处理,通过打开排水阀34来对水过滤器30进行排水(步骤S15)。由此,水过滤器30的容器40内的水和异物穿过容器40的底壁41的排水口41A向导水路33排出,从导水路33被引导向排水路5。特别是,由于排水口41A从容器40的底壁41的上表面部41B向下侧Z2延伸而与导水路33连接,底壁41的上表面部41B以越是临近排水口41A越是下降的方式倾斜(参照图5),因此容器40内的异物不会残留于底壁41,而是顺利地到达排水口41A 并落下,前往导水路33和排水路5。进而,在容器40内的角部分、侧壁46与下挡板47的连接部分、侧壁46与上挡板48的连接部分,设置有R倒角65(参照图5),因此,能防止异物残留于这些角部分或连接部分。虽然控制部60可以在水过滤器30的排水中停止送风部21,但是如果要促进排水,也可以使送风部21工作。
被导入排水路5的异物被排水过滤器6(参照图1)捕获。由于只要去除蓄积于排水过滤器6的异物就能去除容器40内的异物,因此,使用者可以不用进行接触水过滤器30来去除容器40内的异物的维护。因此,能实现烘干运转的使用便利性的提高。需要说明的是,也可以省略排水过滤器6,这种情况下,被引导至排水路5的异物通过排水路5被直接排到机外。
当容器40内的水变空时,烘干运转结束。控制部60既可以根据水位传感器61的检测结果来判断容器40内的水是否变空,也可以根据是否经过了所需时间来判断。该所需时间比容器40内的水位从基准水位W下降到底壁41为止所需的时间长,通过实验等预先确定并存储于存储器63。在从烘干运转结束到下一个烘干运转的步骤S12中打开供水阀32从供水口42E向容器40内供水为止的期间,控制部60保持排水阀34打开,由此使容器40内变空。由此,能防止由于从烘干运转结束到下一次烘干运转开始为止的期间容器40内残留有水而导致霉菌、杂菌在容器40内繁殖。
参照图6,在下一次烘干运转开始时(步骤S12),在容器40中,为了使水过滤器30的功能有效,从侧壁46的内表面部42C的供水口42E供水。供水口42E设置于内表面部42C中的弯曲成圆弧状的弯曲部42D,沿着该弯曲部42D的弯曲横向开口。因此,从供水口42E供给至容器40内的水如图6的粗虚线所示,在容器40内绕纵轴(未图示)旋转,沿着内表面部42C画出螺旋并向排水口41A流下。通过这样旋转的水,能去除附着于侧壁46的内表面部42C的异物,能将这些异物从底壁41的排水口41A排出到导水路33。也就是说,通过每次供水时都对内表面部42C的整个区域进行清洗,能防止内表面部42C处的异物粘附。
此外,供水口42E配置于比出口45B更靠近入口49A的位置。因此,由于能使从入口49A流入容器40内的空气迅速穿过来自供水口42E的水,因此能从 这些空气中迅速去除异物。此外,向容器40的内表面部42C中的容易附着异物的入口49A侧的部分重点喷淋来自供水口42E的水,能从该部分去除异物。进而,从供水口42E供给至容器40内的水被引导部44A向下侧Z2引导,该引导部44A在容器40的侧壁46的内表面部42C遍及整周地设置在高于供水口42E的位置,因此,能使这些水以不向上侧Z1飞溅的方式迅速蓄至容器40内。此外,由于能使水沿着内表面部42C螺旋状流动,因此,能通过水来收集容器40内的异物并可靠地引导向导水路33。
可以想象,在主烘干处理(步骤S13)中的长时间的热风循环中,容器40内的水会因热风而蒸发或溅起等,由此容器40内的水位会降低。当容器40内的水位低于基准水位W时,容器40内的空气会不穿过水地向容器40的外部流出,因此,水过滤器30从循环路20内的空气中捕获异物的性能会降低。相反地,当通过因容器40内的热交换而从潮湿空气中冷凝出来的湿气使得水位超过基准水位W时,入口49A中的浸入容器40内的水的区域会增加。这样,入口49A中的流速会变高,导致容器40内的水翻滚。这种情况下,也会降低水过滤器30捕获异物的性能。因此,控制部60在主烘干处理中执行调整处理,该调整处理将能在容器40内变动的水位调整为最佳的基准水位W。
图12是表示调整处理的流程图。每经过规定时间(步骤S21中为“是”),控制部60就暂停送风部21(步骤S22),根据水位传感器61的检测结果定期确认现在的容器40内的水位是否与基准水位W相比发生了变化(步骤S23)。为了在容器40内的水面稳定的状态下正确检测容器40内的水位,在步骤S22中停止送风部21。如果现在的容器40内的水位与基准水位W相比没有变化(步骤S23中为“是”),则没有特别的问题,因此控制部60使送风部21工作(步骤S24),继续主烘干处理。
在现在的容器40内的水位与基准水位W相比有所变化的情况下(步骤S23中为“否”),当现在的容器40内的水位低于基准水位W时(步骤S25中为“是”),控制部60执行补给处理(步骤S26)。作为补给处理,控制部60将供水阀32打开例如3秒的规定时间,向容器40内补水。通过补给处理,能抑制容器40内的水位降低,将容器40内的水位维持在基准水位W。因此,能抑制水过滤器30的性能降低。在现在的容器40内的水位超过基准水位W的情 况下(步骤S25中为“否”),控制部60执行排水处理(步骤S27)。作为排水处理,控制部60将排水阀34打开例如3秒的规定时间,对容器40进行排水。然后,控制部60返回步骤S23,确认补给处理后或排水处理后的容器40内的水位是否变为了基准水位W,并根据需要重复进行补给处理或排水处理。
洗干一体机1可以不具备水位传感器61,作为该情况的调整处理,可举出第一~第四变形例。图13是表示第一变形例的调整处理的流程图。需要说明的是,在后面说明的各个流程图中,与已经说明的处理步骤相同的处理步骤由相同的步骤编号表示,省略其详细说明。第一变形例中,洗干一体机1包括:入口温度传感器70,检测流过水过滤器30的容器40的入口49A的空气的温度;以及出口温度传感器71,检测流过容器40的出口45B的空气的温度(参照图9)。入口温度传感器70和出口温度传感器71能使用公知的温度传感器。将入口温度传感器70的检测结果称为入口温度,将出口温度传感器71的检测结果称为出口温度。入口温度不必是入口49A的温度,可以是容器40内的空气流动方向上比容器40内的水更靠上游侧的任意区域的温度。出口温度不必是出口45B的温度,可以是容器40内的空气流动方向上比容器40内的水更靠下游侧的任意区域的温度。在继续主烘干处理的状态下,控制部60确认入口温度与出口温度之差(步骤S31)。当容器40内的水位降低时,从入口49A流入容器40内并从出口45B流出的空气的温度难以降低。因此,当容器40内的水位低于基准水位W时,入口温度与出口温度之差变得小于规定的阈值。在这种情况下(步骤S31中为“是”),控制部60执行补给处理(步骤S32)。作为步骤S32中的补给处理,控制部60在将排水阀34打开规定的排水时间而将容器40完全排水后,将供水阀32打开规定的供水时间,向容器40供水直到容器40内的水位达到基准水位W。也就是说,控制部60更换容器40内的水。排水时间和供水时间通过实验等预先确定并存储于存储器63中。
图14是表示第二变形例的调整处理的流程图。第二变形例中,洗干一体机1包括湿度传感器72,该湿度传感器72检测流过水过滤器30的容器40的出口45B的空气的湿度来作为检测值(参照图9)。湿度传感器72能使用公知的湿度传感器。在继续主烘干处理的状态下,控制部60通过湿度传感器72确认出口45B的湿度,具体而言确认绝对湿度(步骤S33)。当容器40内的水位降低 时,容器40内的水变少,因此,从入口49A流入容器40内之后从出口45B流出的空气的湿度也会降低。因此,当容器40内的水位低于基准水位W时,出口45B的湿度变得小于规定的阈值。这种情况下(步骤S33中为“是”),控制部60执行上述的补给处理(步骤S32)。
图15是表示第三变形例的调整处理的流程图。在第三变形例中,洗干一体机1包括风速传感器73,该风速传感器73检测水过滤器30的容器40的出口45B处的风速来作为检测值(参照图9)。风速传感器73能使用公知的风速传感器。在继续主烘干处理的状态下,控制部60确认出口45B的风速(步骤S34)。当容器40内的水位降低时,在容器40内阻碍空气流动的水会减少,因此,空气从容器40内流出而使得流过出口45B的空气的风速增加。因此,当容器40内的水位低于基准水位W时,出口45B的风速超过规定的阈值。在这种情况下(步骤S34中为“是”),控制部60执行上述的补给处理(步骤S32)。
图16是表示第四变形例的调整处理的流程图。第四变形例中,洗干一体机1包括溢水传感器74,该溢水传感器74检测溢水口41F处有无水,也就是说检测来自溢水口41F的溢水(参照图9)。溢水传感器74能使用公知的泡沫检测传感器等。溢水传感器74例如配置于溢水口41F的周边。当容器40内的水位上升至溢水口41F,容器40内的水到达溢水口41F时,溢水传感器74检测到溢水的发生,控制部60将溢水的发生次数加1(+1)。溢水的发生次数存储于存储器63中,在烘干运转开始时初始化为零。在继续主烘干处理的状态下,控制部60确认溢水的发生次数(步骤S35)。当容器40内的水位高于基准水位W时,溢水频发而使得溢水的发生次数超过规定的阈值。在这种情况下(步骤S35中为“是”),控制部60执行上述的补给处理(步骤S32),使容器40内的水位下降到基准水位W。
可以想象,在主烘干处理中的热风的循环中,得容器40内的水温会通过与潮湿空气的热交换而上升。当容器40内的水温上升时,水过滤器30的除湿性能会降低。因此,控制部60在主烘干处理中也就是送风部21和加热部22工作的过程中执行使容器40内的水温降低的冷却处理。
图17是表示冷却处理的流程图。作为冷却处理,例如每隔10分~20分的规定时间(步骤S41中为“是”),控制部60打开供水阀32(步骤S42),将 来自水龙头的冷水供给至容器40内。由此,抑制了容器40内的水温上升,因此能抑制水过滤器30的除湿性能降低。特别是,控制部60在烘干运转中每隔规定时间将供水阀32打开而向容器40内供水,由此定期地抑制容器40内的水温上升,因此,能持续抑制水过滤器30的除湿性能降低。而且,当打开供水阀32后经过规定的供水时间时(步骤S43中为“是”),控制部60关闭供水阀32(步骤S44)。由于控制部60在关闭排水阀34的状态下执行冷却处理,因此,在步骤S42中每隔规定时间打开供水阀32时,也保持排水阀34关闭的状态。因此,容器40内的多余的水穿过溢水口41F向容器40的外部排出。由此,控制部60打开供水阀32向容器40内供水,此时,通过使多余的水从溢水口41F溢出到溢水路35,能向容器40内供给抑制容器40内的水温上升所需的量的水。这种情况下,由于控制部60不为了排出容器40内的水而停止送风部21或打开/关闭排水阀34,因而能实现时间缩短并且降低送风部21和排水阀34的负担。进而,由于浮在容器40内的水面上的异物通过冷却处理被比较频繁地排出,因而能防止大量的异物蓄积在容器40内。
烘干运转中,通过步骤S15中的排水处理,能从容器40内排出水和异物,因此,烘干运转后的容器40内几乎不存在污垢。但是,当反复进行烘干运转时,异物或水垢等会成为顽固污垢并附着于容器40内,仅通过用于开始烘干运转的供水(步骤S12)或烘干运转结束时的排水(步骤S15)可能无法完全去除。因此,控制部60通过使送风部21工作或分别打开/关闭供水阀32和排水阀34,从而执行容器40内的清扫处理。作为控制部60执行清扫处理的时刻,可举出控制部60执行了规定次数的烘干运转之后这一时刻。此外,清扫处理可以在每次烘干运转之后执行。此外,也可以设置检测容器40内的水的浑浊度的公知的浑浊度传感器75(参照图9),在由浑浊度传感器75检测出的浑浊度为规定以上的严峻水平的情况下,控制部60在烘干运转中执行清扫处理。此外,也可以在从前一次的清扫处理经过了规定时间的情况下执行清扫处理。进而,也可以在这次烘干的洗涤物L容易像毛毯等那样出来线屑的情况下执行清扫处理。在烘干运转中执行清扫处理的情况下,控制部60在清扫处理开始之前暂停送风部21和加热部22,对容器40进行排水,由此中断烘干运转。
图18是表示清扫处理的流程图。随着清扫处理的开始,控制部60在关闭 排水阀34的状态下打开供水阀32(步骤S50)。当通过打开供水阀32,容器40内的水位达到规定水位时(步骤S51中为“是”),控制部60关闭供水阀32(步骤S52),打开排水阀34(步骤S53)。这里的规定水位的一例是上述的最大水位。然后,当打开排水阀34后经过规定的排水时间时(步骤S54中为“是”),控制部60关闭排水阀34(步骤S55)。此外,在步骤S55中,控制部60使在清扫处理开始时为零的供水次数加1(+1)。供水次数存储于存储器63中。控制部60反复进行步骤S50~S55的处理直到供水次数达到规定次数。当供水次数达到规定次数时(步骤S56中为“是”),控制部60结束清扫处理。这样,控制部60反复进行规定次数的如下处理:在关闭排水阀34的状态下将供水阀32打开规定时间从而向容器40内蓄水之后,打开排水阀34。这种情况下,能通过蓄于容器40内并被一口气排出的水的势头,将残留于容器40内的异物去除。需要说明的是,在清扫处理中,控制部60也可以使送风部21工作而在容器40内产生风,通过这些风来促进异物的去除。
在清扫处理中,除了以上说明过的处理之外,还能举出第一~第三变形例。图19是表示第一变形例的清扫处理的流程图。第一变形例中,随着清扫处理的开始,控制部60打开供水阀32和排水阀34(步骤S57)。由此,容器40的供水排水同时进行。然后,当打开供水阀32和排水阀34后经过规定时间时(步骤S58中为“是”),控制部60关闭供水阀32和排水阀34(步骤S59),从而结束清扫处理。这样,作为第一变形例的清扫处理,控制部60在打开排水阀34的状态下将供水阀32打开规定时间。这种情况下,能通过被供给至容器40内之后迅速排出的水的势头,将残留于容器40内的异物去除。
图20是表示第二变形例的清扫处理的流程图。第二变形例中,随着清扫处理的开始,控制部60在关闭供水阀32的状态下打开排水阀34并使送风部21工作(步骤S60)。然后,当从步骤S60经过规定时间时(步骤S61中为“是”),控制部60关闭排水阀34并停止送风部21(步骤S62)从而结束清扫处理。这种情况下,能通过容器40内产生的风的势头,将残留于容器40内的异物去除。
图21是表示第三变形例的清扫处理的流程图。第三变形例的清扫处理相当于将第一变形例的清扫处理与第二变形例的清扫处理组合而成的处理。第三变形例中,随着清扫处理的开始,控制部60打开供水阀32和排水阀34,由此同 时进行容器40的供水和排水(步骤S57)。然后,当经过规定时间时(步骤S58中为“是”),控制部60在打开排水阀34的状态下关闭供水阀32并使送风部21工作(步骤S63)。然后,当从步骤S63经过规定时间时(步骤S61中为“是”),控制部60关闭排水阀34并停止送风部21(步骤S62),从而结束清扫处理。这样,作为第三变形例的清扫处理,控制部60在打开排水阀34的状态下将供水阀32打开规定时间之后,使送风部21工作。这种情况下,能通过被供给至容器40内后迅速排出的水的势头和随着送风部21的工作而在容器40内流动的空气的势头,将残留于容器40内的异物去除。
在一次烘干运转中会产生大量异物,或者随着烘干运转的反复进行,大量的异物会附着于容器40内,异物可能会堵塞在容器40内,尤其是排水口41A处。因此,控制部60检测容器40内的异物堵塞,在规定的时刻执行消除该堵塞的处理。作为该时刻,能举出控制部60执行了规定次数的烘干运转之后的时刻、烘干运转中尤其是上述的清扫处理中控制部60打开排水阀34的时刻。
具体而言,参照图22,当控制部60在向容器40内蓄水至例如最大水位的状态下打开排水阀34时(步骤S71中为“是”),通过监视容器40内的水位降低速度来检测异物的堵塞(步骤S72)。水位降低速度通过将规定时间的开始时刻和结束时刻各自的水位传感器61的检测值之差除以该规定时间而得到。水位传感器61的检测值之差为水位降低量。当容器40内被异物堵塞时,容器40内难以排水,因此,水位降低速度低于规定的阈值。当容器40内的水位降低速度低于规定的阈值时(步骤S72中为“是”),控制部60判断容器40内存在异物堵塞(步骤S73)。需要说明的是,控制部60也可以不直接将降低速度与阈值比较,而是通过比较经过规定时间时的水位降低量与对应于水位的阈值,判断容器40内有无异物堵塞。这种情况下,当规定时间的水位降低量低于阈值时,控制部60能判断存在异物堵塞。此外,在步骤S73中,控制部60使初期值为零的检测次数加1(+1)。检测次数存储于存储器63中。
如果检测次数小于规定次数(步骤S74中为“否”),则控制部60使送风部21工作或分别打开/关闭供水阀32和排水阀34,执行消除异物堵塞的消除处理(步骤S75)。因此,即使容器40内堵塞了异物,使用者也可以不进行接触水过滤器30来消除容器40内的异物堵塞的维护,因而,能实现烘干运转的使 用便利性的提高。后面会对消除处理进行详细说明。消除处理之后,控制部60关闭排水阀34并打开供水阀32,由此向容器40内供水(步骤S76)。当容器40内的水位上升至规定水位时(步骤S77中为“是”),控制部60关闭供水阀32并打开排水阀34,由此对容器40进行排水(步骤S78)。这里的规定水位的一例为前述的最大水位。控制部60监视该排水中容器40内的水位降低速度,由此再次检测异物堵塞(步骤S79)。当水位降低速度低于规定的阈值时(步骤S79中为“是”),控制部60判断为容器40内仍然存在异物堵塞,将检测次数加1(步骤S73)。需要说明的是,步骤S79的阈值和步骤S72的阈值既可以相同,也可以不同。
控制部60反复进行消除处理(步骤S75)和异物堵塞的再次检测(步骤S76~S79),直到检测次数达到规定次数。检测次数是控制部60判断容器40内存在异物堵塞的次数。在检测次数达到规定次数的情况下,也就是说在容器40内异物堵塞严重到难以在洗干一体机1内自动消除的程度的情况下(步骤S74中为“是”),控制部60通过显示操作部11的显示或蜂鸣器(未图示)的警报,向使用者告知水过滤器30发生了容器40内的严重异物堵塞这一异常(步骤S80)。换句话说,即使使用者不接触水过滤器30进行维护,不严重的异物堵塞也能在洗干一体机1内被自动消除,因此,能实现使用便利性的提高。在步骤S80中,控制部60可以中止或中断烘干运转。
图23是表示步骤S75的消除处理的流程图。随着消除处理的开始,控制部60打开供水阀32和排水阀34(步骤S81)。由此,同时进行容器40的供水和排水。然后,当打开供水阀32和排水阀34后经过规定时间时(步骤S82中为“是”),控制部60关闭供水阀32和排水阀34(步骤S83),从而结束消除处理。这样,作为消除处理,控制部60在排水阀34打开的状态下将供水阀32打开规定时间。这种情况下,能通过被供给至容器40内后迅速排出的大量的水的势头,将堵塞在容器40内的异物去除并强制排出到导水路33。
消除处理中,除了以上说明的处理之外,还可以举出第一和第二变形例。图24是表示第一变形例的消除处理的流程图。第一变形例中,随着消除处理的开始,控制部60关闭排水阀34并打开供水阀32,向容器40内供水(步骤S84)。由此,当容器40内的水位上升至规定水位时(步骤S85中为“是”),控制部 60关闭供水阀32并打开排水阀34,由此对容器40进行排水(步骤S86)。这里的规定水位的一例为上述的最大水位。这样,作为第一变形例的消除处理,控制部60在关闭排水阀34的状态下将供水阀32打开规定时间从而向容器40内蓄水后,打开排水阀34。这种情况下,能通过蓄于容器40内并被一口气排出的大量的水的势头,将堵塞在容器40内的异物去除并强制排出到导水路33。
图25是表示第二变形例的消除处理的流程图。第二变形例中,随着消除处理的开始,控制部60在关闭供水阀32的状态下打开排水阀34(步骤S87)。当通过打开排水阀34,使得容器40内的水位降低至规定水位时(步骤S88中为“是”),控制部60在打开排水阀34的状态下使送风部21工作(步骤S89)。该规定水位只要是即使送风部21工作容器40内的水也不会飞溅的程度的水位即可,此时的容器40内也可以不是空的。在容器40内的水位降低至规定水位的状态下,控制部60使送风部21的旋转叶片23高速旋转,使得空气以比烘干运转时更强的势头在循环路20内流动。因此,能通过大量的空气的势头,将堵塞在容器40内的异物去除并强制排出到导水路33。然后,当从步骤S89经过规定时间时(步骤S90中为“是”),控制部60停止送风部21(步骤S91),从而结束消除处理。
本发明不局限于如上进行了说明的实施方式,可以在技术方案所述的范围内进行各种变更。
例如,上述实施方式中,水过滤器30配置于箱体2的后区域2C的下部。只要容器40内的水、热气不会到达送风部21、加热部22,也可以像图26所示的变形例那样,将水过滤器30配置在后区域2C的上部。需要说明的是,图26中,对于功能与上述构件相同的构件,赋予相同的符号。
上述实施方式中的滚筒式洗干一体机1中,也可以以轴线J向水平方向H倾斜的方式配置洗涤筒7。此外,洗干一体机1也可以是轴线J纵向延伸的立式洗干一体机。
上述实施方式中的各种处理也可以适当组合来执行。
