Description

洗干一体机 技术领域
本发明涉及一种洗干一体机。
背景技术
下述专利文献1所述的洗干一体机包括可蓄水的外筒、配置于外筒内并收容洗涤物的滚筒、以及循环风路。循环风路包括与外筒连接的进风口和排风口、以及具有鼓风机和加热器的送风单元。当鼓风机工作时，外筒内的空气以从进风口被吸入循环风路内并从排风口流入外筒内的方式进行循环。循环的空气在循环风路内通过加热器被加热。滚筒内的洗涤物通过加热后的空气烘干。捕获循环的空气中所含的碎线等异物的烘干过滤器配置于送风单元。为了方便清扫，烘干过滤器能从送风单元卸下来。

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，其能实现对于烘干过滤器的维护性的提高。
用于解决问题的方案
本发明是一种洗干一体机，包括：箱体；外筒，由所述箱体支承并可蓄水； 洗涤筒，收容于所述外筒内并收容洗涤物；循环路，具有与所述外筒连接的取出口以及返回口；送风部，将所述外筒内的空气通过从所述取出口取出至所述循环路内并从所述返回口返回至所述外筒内而使其循环；加热部，设置于所述循环路内，加热所述循环路内的空气；烘干过滤器，在所述循环路内设置于比所述加热部更靠所述取出口侧，且具有在所述循环路内捕获从所述取出口前往所述返回口的空气中的异物的下表面部；喷射部，具有水的喷射口，并从所述喷射口朝向所述下表面部喷水；以及排水过滤器，捕获从所述外筒排出的水中的异物，且能拆装于所述箱体。
此外，本发明的特征在于，所述下表面部相对于水平方向倾斜地配置，所述喷射部朝向所述下表面部的上端喷水。
此外，本发明的特征在于，所述洗干一体机还包括水引导部，该水引导部将从所述喷射口喷射的水以沿着所述下表面部扩散的方式引导。
此外，本发明的特征在于，所述洗干一体机还包括异物引导部，该异物引导部将通过从所述喷射部喷射的水而从所述下表面部剥落的异物引导向所述取出口。
此外，本发明的特征在于，在所述喷射部朝向所述下表面部喷水之后，所述送风部使所述外筒内的空气循环。
发明效果
根据本发明，洗干一体机的外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外筒内的方式循环。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。在循环路内设置于比加热部更靠取出口侧的烘干过滤器在下表面部捕获为了循环而在循环路内从取出口前往返回口的空气中所含的异物。因此，能抑制空气中的异物附着于加热部。当喷射部从喷射口朝向烘干过滤器的下表面部喷水时，存留于下表面部的异物从下表面部剥离，从取出口到达外筒内，并在外筒排水时被排水过滤器捕获。由排水过滤器捕获的异物在使用者卸下排水过滤器进行维护时被去除。
这样，洗干一体机具有烘干过滤器的自动维护功能，因而使用者可以不将烘干过滤器卸下进行维护。因此，能实现对于烘干过滤器的维护性的提高。
此外，根据本发明，喷射部在烘干过滤器中朝向相对于水平方向倾斜地配置的下表面部的上端喷水，因而能将存留于下表面部的异物无残留地从下表面部剥离。因此，能实现对于烘干过滤器的维护性的进一步提高。
此外，根据本发明，从喷射部的喷射口喷射的水沿着烘干过滤器的下表面部扩散，因而能将存留于下表面部的异物无残留地从下表面部剥离。因此，能实现对于烘干过滤器的维护性的进一步提高。
此外，根据本发明，通过从喷射部喷射的水而从烘干过滤器的下表面部剥落的异物通过异物引导部被引导向取出口。因此，能将被烘干过滤器的下表面部捕获的异物以不会再次附着于烘干过滤器的方式从取出口排出至外筒内。因此，能实现对于烘干过滤器的维护性的进一步提高。
此外，根据本发明，在喷射部朝向烘干过滤器的下表面部喷水之后，外筒内的空气进行循环并穿过烘干过滤器，由此将烘干过滤器烘干。因此，使用者可以不对因喷水而被打湿的烘干过滤器进行烘干。因此，能实现对于烘干过滤器的维护性的进一步提高。

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的上游侧的区域的旋转叶片23、以及使旋转叶片23旋转的马达(未图示)。当旋转叶片23旋转时，外筒3内的空气也就是外筒3内以及洗涤筒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返回至外筒3内。由此，外筒3内的空气以按顺序流过外筒3和循环路20的方式循环。
加热部22为热泵中的热交换器或普通的加热器等，至少一部分加热部22设置于循环路20内。加热部22中设置于循环路20内的部分具有多个翅片状的散热部22A。由于当加热部22工作时散热部22A变得高温，因而流过循环路20内的空气在经过散热部22A的周围时会被加热变成热风。
洗干一体机1包括被配置为微型计算机的控制部24。控制部24通过控制马达8、供水阀11、排水阀12、送风部21以及加热部22的动作来执行洗涤烘干运转。洗涤烘干运转包括洗涤过程、漂洗过程、脱水过程、以及烘干过程。
在洗涤过程开始之前，向洗涤筒7内投入洗涤剂。在洗涤过程中，控制部24将供水阀11打开规定时间向外筒3以及洗涤筒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被敲洗。敲洗中，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“翻滚”。通过翻滚产生的冲击、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。从翻滚开始经过规定时间之后，当控制部24打开排水阀12进行排水时，洗涤过程结束。
在漂洗过程中，控制部24将供水阀11打开规定时间向外筒3以及洗涤筒7供水，之后通过马达8使洗涤筒7旋转。这样，由于上述的翻滚反复进行，因而洗涤物L通过洗涤筒7内的自来水被漂洗。从翻滚开始经过规定时间之后，当控制部24进行排水时，漂洗过程结束。漂洗过程可以反复进行多次。在脱水过程中，控制部24在打开了排水阀12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的脱水旋转产生的离心力被脱水。通过脱水从洗涤物L渗出的水从排水路5排出至机身外。脱水过程不仅在漂洗过程之后实施，也可以在洗涤过程之后也实施。
在烘干过程中，控制部24通过送风部21以及加热部22产生热风并使其在洗涤筒7与循环路20之间循环，供给至洗涤筒7内的洗涤物L。由此，烘干洗涤物L。在洗涤运转中产生碎线等异物，该异物在烘干过程中随着热风流动。由于当异物附着于加热部22的散热部22A并累积时，可能会产生伴随加热部22的加热效率降低、循环路20中的空气流动的恶化而来的性能降低，因而需要捕获该异物。因此，烘干单元9还包括过滤构件25、喷射部26、支路27、以及注水阀28。以下，在对构成烘干单元9的送风部21以及循环路20进行详细说明之后，对过滤构件25、喷射部26、支路27以及注水阀28进行说明。
图2是从后侧Y2观察外筒3以及烘干单元9的立体图。送风部21包括收容有旋转叶片23的中空圆盘状的壳体29。壳体29为循环路20的一部分，壳体29的内部空间构成循环路20内的中途部分20A与后部分20B的连接部。
图3是外筒3以及烘干单元9的分解立体图。循环路20包括几乎占据整个后部分20B的管道30、以及连接壳体29与管道30的连接软管31。管道30包括主体32以及罩33。主体32具有沿洗涤筒7的圆周壁7A的右上部分弯曲的弯曲壁32A、从弯曲壁32A的左端向右侧X2延伸的顶壁32B、从顶壁32B的右端折曲的同时向下侧Z2延伸并与弯曲壁32A的右端连接的侧壁32C、以及与弯曲壁32A、顶壁32B和侧壁32C各自的前端连接的前壁32D。在主体32，形成有由弯曲壁32A、顶壁32B以及侧壁32C包围并由前壁32D从前侧Y1堵住的上空间32E。在顶壁32B的上表面的左区域，设置有向上侧Z1突出的圆筒状 的上连结部32F。上连结部32F的内部空间处于从上侧Z1与上空间32E连通的状态。上空间32E以及上连结部32F的内部空间构成循环路20的后部分20B的内部空间的一部分。
主体32还包括从弯曲壁32A的后端向下侧Z2并且向轴线J侧延伸的纵壁32G、以及从纵壁32G中与弯曲壁32A连接的上端缘之外的外缘向后侧Y2立起的外壁32H。纵壁32G具有与前后方向Y一致的板厚方向。上述的取出口20D有两个，并形成为在纵壁32G的下端部绕着轴线J的周向S排列。各个取出口20D是周向S上长的长孔，沿前后方向Y贯通纵壁32G。在纵壁32G，将取出口20D包边并向前侧Y1突出的筒状的下连结部32I与各个取出口20D对应地逐一设置。在外筒3的背面壁3B的上部，形成有与取出口20D相同形状的两个贯通孔3K。各个下连结部32I从后侧Y2嵌入对应的贯通孔3K。由此，取出口20D与背面壁3B连接而与外筒3内连通。
在纵壁32G的后表面，设置有向后侧Y2突出的引导肋32J。引导肋32J在纵壁32G的上端从偏右侧X2的位置沿上下方向Z直线状延伸至右边的取出口20D的跟前。外壁32H形成为背面观察时大致U字状，在其内侧划分出下空间32K。下空间32K在前后方向Y上扁平，由纵壁32G从前侧Y1堵住，处于从下侧Z2与上空间32E的后端部连通的状态。下空间32K构成循环路20的后部分20B的内部空间的一部分。在上空间32E，设置有与引导肋32J的上端相连并向前侧Y1延伸的分隔部32L(也参照图2)。
罩33为具有与背面观察下的主体32大致一致的形状的板状，具有与前后方向Y一致的板厚方向。罩33通过螺钉等紧固件(未图示)可拆装地装配于主体32。装配于主体32的状态下的罩33从后侧Y2堵住主体32的上空间32E以及下空间32K。
连接软管31例如为橡胶制的圆筒，其内部空间向上侧Z1以及下侧Z2敞开。连接软管31的大致下半部分为蛇腹部31A。在连接软管31的大致上半部分的外周面，设置有向左侧X1突出的圆管状的管部31B。连接软管31的下部外嵌于管道30的上连结部32F。连接软管31的上部经由过滤构件25与送风部21的壳体29连结，后面会详细说明。连接软管31的内部空间构成循环路20的后部分20B的内部空间的一部分。
过滤构件25包括具有向上侧Z1和下侧Z2敞开的内部空间的圆筒部25A、以及从过滤构件25的上端向圆筒部25A的径向外侧突出的圆环状的外凸缘部25B。在圆筒部25A的左端，形成有从圆筒部25A的下端向上侧Z1凹陷的切口25C。参照作为过滤构件25的仰视图的图4，在圆筒部25A的内周面的上下方向Z的中途，设置有向过滤构件25的径向内侧突出的圆环状的内凸缘部25D。在过滤构件25，设置有配置于由内凸缘部25D的内周缘围成的圆孔25E的烘干过滤器40。烘干过滤器40为具有与圆孔25E相同大小的圆板状，遍及圆孔25E的整个区域地设置。烘干过滤器40可以是如图4所示与内凸缘部25D一体形成的栅格，也可以是通过粘接等装配于内凸缘部25D的网眼片。图4的烘干过滤器40中，放大地图示了下表面部40A。下表面部40A为形成有许多栅格口或网眼的平坦面，与内凸缘部25D的下表面相连。
在过滤构件25的圆筒部25A的内周面，在其周向P的切口25C的两侧，逐一设置也就是合计设置一对朝向烘干过滤器40延伸的纵壁25F。一对纵壁25F形成为仰视时以先分离后接近的方式折曲为L字状。各个纵壁25F的上端与内凸缘部25D的下表面连接。
在内凸缘部25D的下表面中偏向径向内侧也就是烘干过滤器40侧的区域，设置有多个向下侧Z2突出的肋状的第一水引导部25G。这些第一水引导部25G仰视时以切口25C为基准放射状且直线状地延伸，在一对纵壁25F之间沿周向P大致等间隔排列地配置。位于周向P上的两端的第一水引导部25G分别与一对纵壁25F的烘干过滤器40侧的端部连接。各个第一水引导部25G仰视时配置于内凸缘部25D的内周缘与圆筒部25A的内周面之间，并远离内凸缘部25D的内周缘以及圆筒部25A的内周面地配置。各个第一水引导部25G的下端与各个纵壁25F的下端配置于相同的高度位置。
在圆筒部25A的内周面，设置有突出至内凸缘部25D的内周缘的跟前的突出部25H。例如三个突出部25H沿周向P等间隔排列地设置。突出部25H逐一设置于与沿周向P排列的多个第一水引导部25G中分别位于两端的两个第一水引导部25G邻接的位置、相对于烘干过滤器40的切口25C的相反侧的位置。在各个突出部25H的下表面形成有螺纹孔25I。
过滤构件25通过紧固件(未图示)从下侧Z2固定于壳体29，该紧固件穿 过形成于外凸缘部25B的贯通孔25J组装于送风部21的壳体29(参照图3)。过滤构件25和壳体29可以是一个部件而不是分开的部件。连接软管31的上部外嵌于过滤构件25的圆筒部25A，在这种状态下，圆筒部25A的切口25C从连接软管31的内侧与连接软管31的管部31B的内部空间连通(参照图3)。圆筒部25A的内部空间构成循环路20的后部分20B的内部空间的一部分，连接壳体29的内部空间和连接软管31的内部空间。
图5是喷射部26的俯视图。喷射部26包括具有向上侧Z1和下侧Z2敞开的内部空间的圆筒部26A、以及设置于圆筒部26A的周向上的一处并向圆筒部26A的径向R的外侧突出的圆弧状的突出部26B。圆筒部26A的大致上半部分的内径与烘干过滤器40的外径大致相等。圆筒部26A的大致下半部分越往下侧Z2越是缩径(参照图3)。圆筒部26A的大致下半部分的内周面为越往下侧Z2越是缩径的锥形的第一异物引导部26C。在圆筒部26A的上端，形成有仅切除了在其周向Q上位于与突出部26B相同位置的部分的喷射口26D。喷射口26D为沿周向Q圆弧状延伸的狭缝。在周向Q上的喷射口26D的位于中央部的圆筒部26A的上端面，形成有向上侧Z1稍稍隆起的第二水引导部26E。在圆筒部26A的上端，设置有从周向Q的两侧夹着喷射口26D的一对第三水引导部26F。一对第三水引导部26F以相互接近的方式延伸，各自的顶端从喷射口26D向径向R的外侧突出地配置。
突出部26B的上表面26G为配置在低于喷射口26D的圆筒部26A的上端面的位置并沿周向Q圆弧状地延伸的平坦面。在上表面26G中偏向径向R的外侧的位置，形成有向下侧Z2凹陷的槽26H。槽26H沿周向Q圆弧状延伸。在上表面26G中径向R的外侧的周缘处，形成有将槽26H包边并且向上侧Z1突出的肋26I。周向Q上的肋26I的两端部以相互接近的方式折曲。在突出部26B中径向R的外侧的外周面，设置有向该外侧直线状延伸的圆管状的管部26J。管部26J的内部空间处于与周向Q上的槽26H的中央部的下部连通的状态。
在圆筒部26A的外周面，设置有向径向R的外侧突出的突出部26K。例如三个突出部26K沿周向Q等间隔排列地设置，其中的两个突出部26K逐一设置于周向Q上的突出部26B的两侧。在各个突出部26K，形成有沿上下方向Z贯通突出部26K的贯通孔26L。
图6是组合后的过滤构件25以及喷射部26的仰视图。喷射部26从下侧Z2组装于过滤构件25。图7是图6的A－A剖面图。喷射部26的圆筒部26A嵌入过滤构件25的圆筒部25A内，圆筒部25A的周向P与圆筒部26A的周向Q一致。圆筒部26A中的各个突出部26K配置于圆筒部25A中的任意一个突出部25H的正下方。紧固件41(参照后述的图11)穿过突出部26K的贯通孔26L组装于突出部25H的螺纹孔25I，由此，喷射部26固定于过滤构件25。圆筒部26A的内部空间构成循环路20的后部分20B的内部空间的一部分。
在固定于过滤构件25的喷射部26中，圆筒部26A的上端面处于遍及喷射口26D之外的整个区域地与过滤构件25的内凸缘部25D的下表面接触的状态。仰视时，烘干过滤器40的下表面部40A配置于圆筒部26A的内侧(参照图6)。
图8是图7的B－B剖面图。图9是图8中由双点划线包围的部分的放大图。喷射口26D处于被内凸缘部25D中的平坦的下表面从上侧Z1堵住的状态，沿周向P细长地延伸。在喷射口26D中，将周向P上的中央部称为第一区域26DA，将第一区域26DA的两外侧的部分称为第二区域26DB。第一区域26DA在圆筒部26A的上端面处与向上侧Z1隆起的第二水引导部26E在周向P上一致，第二区域26DB与圆筒部26A的上端面中的从第二水引导部26E偏离的部分一致。由此，第一区域26DA处于比第二区域26DB更向上侧Z1收缩的状态，在上下方向Z上比第二区域26DB窄。
图10是图7中由双点划线包围的部分的放大图。设置于内凸缘部25D的下表面的纵壁25F以及第一水引导部25G(参照图4)各自的下端处于从上侧Z1与喷射部26的突出部26B的上表面26G中的比槽26H更靠径向R的内侧的区域接触的状态。一对纵壁25F从周向P夹住设置于上表面26G的肋26I，位于周向P上的两端的第一水引导部25G处于与圆筒部26A中的夹着喷射口26D的一对第三水引导部26F的顶端逐一相连的状态(参照图5)。
在突出部26B的上表面26G与内凸缘部25D的下表面中的位于上表面26G的正上方的部分之间，形成有中继空间42。中继空间42为仰视时沿着周向P延伸的圆弧状的空间(参照图6)。中继空间42中的位于径向R的外侧的外侧空间42A处于从正上方与槽26H连通的状态。中继空间42中的位于径向R的内侧的内侧空间42B的上端处于从径向R的外侧与喷射口26D连通的状态。像这样， 中继空间42将槽26H和喷射口26D接到一起。在内侧空间42B，上述的多个第一水引导部25G沿周向P排列配置(参照图5)。中继空间42处于被一对纵壁25F和与各个纵壁25F相连的第一水引导部25G从周向P的两侧堵住并被肋26I从径向R的外侧堵住的状态(参照图5)。
图11是烘干单元9的纵剖面后视图。过滤构件25以及喷射部26以使烘干过滤器40的下表面部40A相对于水平方向H倾斜的方式配置。作为一个例子，在本实施方式中，下表面部40A以左端成为上端40B且右端成为下端40C的方式倾斜配置。烘干过滤器40在循环路20内设置于比加热部22以及送风部21的旋转叶片23更靠取出口20D侧也就是上游侧(参照图1)。喷射部26的喷射口26D从左侧X1面向上端40B地配置于下表面部40A。喷射部26的管部26J中，根部从下侧Z2嵌入过滤构件25的圆筒部25A的切口25C，顶端部处于穿过切口25C以及连接软管31的管部31B内伸向径向R的外侧的状态。
支路27从供水路4中的比供水阀11更靠近水龙头的上游部分支，并与喷射部26的管部26J的顶端部连接(参照图1)。注水阀28设置于支路27(参照图1)。注水阀28为了将从供水路4流向支路27的水供给至管部26J、或停止该供给而被开闭。注水阀28的开闭通过控制部24(参照图1)控制。
烘干过程中，如上所述通过送风部21以及加热部22产生热风并使其循环。该热风在循环路20内从取出口20D前往返回口20E，在其中途的后部分20B上升的同时穿过烘干过滤器40(参照图1的粗虚线的箭头)。烘干过滤器40的下表面部40A从该热风中捕获异物T。因此，随着烘干过程的进行，异物T存留于下表面部40A。由此，能抑制异物T附着于在循环路20内比烘干过滤器40更从取出口20D向下游侧偏离地设置的加热部22。
在烘干过程之后也就是洗涤烘干运转结束之后，控制部24打开注水阀28。需要说明的是，供水阀11可以设置于供水路4中的比支路27的分支位置更靠近水龙头的上游侧，在这种情况下，控制部24将供水阀11以及注水阀28双方打开。来自水龙头的水经由供水路4以及支路27供给至喷射部26。
供给至喷射部26的水流入管部26J内，按顺序穿过槽26H以及中继空间42，从喷射口26D朝向下表面部40A的上端40B喷射(参照虚线箭头V)。流过中继空间42的内侧空间42B的水穿过相邻的第一水引导部25G之间，这时，通过 第一水引导部25G以及第三水引导部26F，扩散至喷射口26D的整个区域(参照图5)。此外，喷射口26D以只有中央的第一区域26DA会被第二水引导部26E收紧的方式构成(参照图9)。由此，流过喷射口26D的水的强度在第一区域26DA中变强，并且以水在喷射口26D中不只往来于第一区域26DA还往来于第二区域26DB的方式被调整水量。以上的结果是，喷射部26内的水以沿烘干过滤器40的下表面部40A呈扇状扩散的方式被第一水引导部25G、第二水引导部26E以及第三水引导部26F引导，同时强劲地从喷射口26D喷射(参照图5的粗虚线箭头以及图1的水W)。
存留于烘干过滤器40的下表面部40A的异物T像这样借助从喷射口26D喷射的水的强度、异物T的自重从下表面部40A剥离，落到喷射部26的圆筒部26A内。尤其是，从喷射口26D喷射的水通过沿下表面部40A呈扇状扩散，使得下表面部40A上的异物T一齐剥离。落下的异物T通过圆筒部26A中的锥形的第一异物引导部26C，被引导向管道30中的位于圆筒部26A的正下方的上连结部32F内。由此，从下表面部40A剥落的异物T不会四散而被连接软管31的蛇腹部31A，而会穿过上连结部32F内落到管道30的上空间32E，置于管道30的主体32中的弯曲壁32A的上表面。弯曲壁32A的上表面为第二异物引导部32M，以朝向管道30的下空间32K下降的方式倾斜(参照图2)。异物T通过第二异物引导部32M被引导至下空间32K而顺利地到达取出口20D。这时，上述的分隔部32L以及引导肋32J(参照图3)也可以与第二异物引导部32M同样地引导异物T。到达取出口20D的异物T从取出口20D落到外筒3内。从喷射口26D喷向烘干过滤器40的下表面部40A的水也与异物T同样从管道30落到外筒3内并存留于外筒3内。
当注水阀28打开后经过规定时间时，控制部24通过关闭注水阀28来停止喷射部26的喷水，并打开排水阀12。需要说明的是，喷射部26喷水的过程中，排水阀12可以始终处于打开的状态。当排水阀12打开时，存留于外筒3内的水带着异物T流入排水路5。这时，异物T被排水过滤器6(参照图1)捕获。当使用者在适当的时机卸下排水过滤器6进行维护时，被排水过滤器6捕获的异物T被去除。
如上所述，由于洗干一体机1具有自动维护烘干过滤器40的功能，因而不 需要使用者卸下烘干过滤器40进行维护的作业。因此，能实现对于烘干过滤器40的维护性的提高。因此，由于烘干过滤器40可以是不可拆卸的，所以能实现比拆装式的烘干过滤器构造简化、成本降低。此外，在拆装式的烘干过滤器的情况下，如果使用者忘记维护，就可能产生上述的性能降低的现象，而具有自动维护功能的洗干一体机1则能避免忘记维护导致的性能降低。此外，由于能将拆装式的烘干过滤器的情况下需要的配置空间活用于其他用途，因而能通过例如将加热部22、旋转叶片23大型化来实现性能的提高。
喷射部26朝向烘干过滤器40中的相对于水平方向H倾斜配置的下表面部40A的上端40B喷水。然后，从喷射部26的喷射口26D喷射的水沿烘干过滤器40的下表面部40A扩散(参照图5的粗虚线箭头)。因此，能将存留于下表面部40A的异物T无残留地从下表面部40A剥离。因此，能实现对于烘干过滤器40的维护性的进一步提高。
进而，通过从喷射部26喷射的水而从烘干过滤器40的下表面部40A剥落的异物T通过第一异物引导部26C以及第二异物引导部32M被引导向取出口20D。由此，能将在烘干过滤器40的下表面部40A捕获的异物T以不会再附着于烘干过滤器40的方式，从取出口20D排出至外筒3内。因此，能实现对于烘干过滤器40的维护性的进一步提高。
作为烘干过滤器40的自动维护的一环，在停止喷射部26的喷水之后，控制部24通过送风部21使外筒3内的空气循环。为了去除异物T而在之前被喷水打湿的烘干过滤器40通过被从外筒3流入循环路20的空气吹拂而被烘干。需要说明的是，也可以通过使加热部22也进行工作来使热风循环，由此，能促进烘干过滤器40的烘干。这样一来，由于使用者可以无需将烘干过滤器40烘干，因而能实现对于烘干过滤器40的维护性的进一步提高。
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，上述实施方式中的滚筒式的洗干一体机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可以是轴线J纵向延伸的立式洗干一体机。
