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，其能实现对烘干过滤器的维护性的提高，能通过烘干过滤器捕获大量的异物。
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，可蓄水；洗涤筒，收容于所述外筒内，收容洗涤物；循环路，具有与所述外筒连接的取出口和返回口；送风部，将所述外筒内的空气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，由此使所述外筒内的空气循环；加热部，设置于所述循环路内，加热所述循环路内的空气；多个烘干过滤器，在所述循环路内配置于比所述加热部更靠所述取出口侧，并以在所述循环路内的空气的流向上重叠的方式配置，分别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纵面部；以及供水部，从上侧向所述多个烘干过滤器的所述纵面部供水。
此外，本发明的所述洗干一体机的特征在于，还包括：一对纵壁，从横向夹着所述多个烘干过滤器中相邻的烘干过滤器之间的空间；以及底壁，架设在所述一对纵壁之间并从下侧堵住所述空间，所述供水部从上侧堵住所述空间，在所述一对纵壁中的一方，形成有面向所述空间之外的释放孔，所述底壁的上表面部随着临近所述释放孔而下降，与所述释放孔相连。
此外，本发明的特征在于，所述供水部具有供水口，所述供水口与所述多个烘干过滤器相应地设有多个，所述供水口从上侧面向对应的所述烘干过滤器的所述纵面部。
此外，本发明的特征在于，所述供水口以沿着对应的所述烘干过滤器的所述纵面部横向排列的方式设有多个，各个所述供水口沿纵向直线状地延伸。
此外，本发明的特征在于，所述供水部具有使从所述流入口流入的水向所述供水口流出的流路，所述流路具有流入口并与所述供水口连接，所述流入口的流路面积大于所有的所述供水口的流路面积的总和。
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。循环的空气在循环路内被加热部加热从而成为热风，使洗涤筒内的洗涤物烘干。在循环路内设置在比加热部更靠取出口侧的烘干过滤器在纵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。烘干过滤器设有多 个，以在循环路内的空气的流向上重叠的方式配置，因此，流过循环路内的空气依次通过多个烘干过滤器。因此，能通过这些烘干过滤器，从流过循环路内的空气中捕获大量的异物。
当供水部从上侧向各个烘干过滤器的纵面部供水时，被捕获而附着于纵面部的异物通过在纵面部流下的水，从纵面部剥离。该异物在循环路内落下，从取出口到达外筒内，在外筒排水时被从外筒内去除。如此一来，洗干一体机具有自动维护烘干过滤器的功能，因而使用者可以不用卸下烘干过滤器进行维护。因此，能实现对烘干过滤器的维护性的提高。
此外，根据本发明，多个烘干过滤器当中，相邻的烘干过滤器之间的空间由一对纵壁从横向夹住，由架设于这些纵壁之间的底壁从下侧堵住，由供水部从上侧堵住。由此，能防止穿过烘干过滤器而到达相应的空间的空气不到达下一个烘干过滤器而是漏出到相应的空间之外。因此，由于流过循环路内的空气可靠地依次通过多个烘干过滤器，因此，能通过这些烘干过滤器，从流过循环路内的空气中捕获大量的异物。
最靠近取出口的烘干过滤器的纵面部直接露出到循环路内。因此，当从供水部向该纵面部供水时，附着于该纵面部的异物从纵面部剥离后迅速地在循环路内落下并从取出口到达外筒内。
另一方面，夹着相邻的烘干过滤器之间的空间而相邻的烘干过滤器当中，在循环路内的空气的流向上位于下游侧的烘干过滤器的纵面部配置为面向相应的空间，因此不会直接露出至循环路内。在一对纵壁中的一方，形成有面向相应的空间的外部的释放孔，底壁的上表面部以随着临近释放孔而下降并与释放孔相连的方式倾斜。当从供水部向面向相应的空间的纵面部供水时，附着于该纵面部的异物剥离，在相应的空间中落下而置于底壁的上表面部，沿着相应的上表面部的倾斜滑落而到达释放孔。到达释放孔的异物去到相应的空间的外部，在循环路内落下，从取出口到达外筒内。因此，不仅是在最靠近取出口的烘干过滤器的纵面部被捕获的异物，在相邻的烘干过滤器之间的空间中被捕获的异物也通过供水部所进行的供水被送入外筒内。因此，使用者可以不卸下烘干过滤器来从该空间去除异物，因而能进一步实现对烘干过滤器的维护性的提高。
此外，根据本发明，设置于供水部的多个供水口均从上侧面向多个烘干过 滤器当中对应的烘干过滤器的纵面部。由此，来自对应的供水口的水从上侧淋至各个烘干过滤器的纵面部，因而能可靠地从各个烘干过滤器的纵面部剥离异物。因此，能进一步实现对烘干过滤器的维护性的提高。
此外，根据本发明，供水口以沿着对应的烘干过滤器的纵面部横向排列的方式设有多个，各个供水口沿纵向直线状地延伸。由此，从横向排列的多个供水口各自落下的水从上侧淋至各个烘干过滤器的纵面部，因而能可靠地剥离该纵面部的横向上的大范围内的异物。因此，能进一步实现对烘干过滤器的维护性的提高。
此外，根据本发明，供水部中，从流入口流入流路的水从各个供水口流出，从上侧淋至烘干过滤器的纵面部。流入口的流路面积大于所有的供水口的流路面积的总和。由此，能使从流入口流入到流路的水遍布流路的整个区域，因而能使流路内的水从各个供水口以相同的势头于相同的时刻流出。因此，能从各个烘干过滤器的纵面部均匀并且同时地剥离异物。因此，能进一步实现对烘干过滤器的维护性的提高。

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的示意性纵剖左视图。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的纸面的里侧称为右侧X1，将图1的纸面的表侧称为左侧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。洗干一体机1包括：箱体2、配置于箱体2内的外筒3、与外筒3连接的供水路4和排水路5、捕获穿过排水路5从外筒3排出的水中的异物的排水过滤器6、收容于外筒3内的洗涤筒7、使洗涤筒7旋转的马达8以及使洗涤筒7内的洗涤物L烘干的烘干部9。
箱体2形成为箱状。箱体2的前表面2A例如为垂直面。在前表面2A，形成有使箱体2的内外连通的开口2B。在前表面2A，设有对开口2B进行开闭的门10。
外筒3经由吊棒(未图示)由箱体2弹性支承。外筒3具有以沿水平方向H 向前后方向Y延伸的轴线J为中心的圆筒状的圆周壁3A、从后侧Y2堵住圆周壁3A的中空部分的圆盘状的背面壁3B以及与圆周壁3A的前端缘相连的环状的正面壁3C。背面壁3B垂直配置，具有外周部3D和向外周部3D的后侧Y2突出一级的中央部3E。在中央部3E的中心，形成有沿轴线J在前后方向Y上贯通中央部3E的贯通孔3F。正面壁3C具有：从圆周壁3A的前端缘向轴线J侧突出的圆环状的第一部3G、从第一部3G的内周缘向前侧Y1突出的圆筒状的第二部3H以及从第二部3H的前端缘向轴线J侧突出的圆环状的第三部3I。在第三部3I的内侧，形成有从前侧Y1与圆周壁3A的中空部分连通的出入口3J。出入口3J从后侧Y2与箱体2的开口2B对置并连通。
供水路4具有与水龙头(未图示)连接的一端(未图示)和与外筒3的背面壁3B中的例如中央部3E连接的另一端4A。供水时，来自水龙头的水从供水路4供给至外筒3内。外筒3内蓄有自来水、自来水中溶解有洗涤剂的洗涤剂水等水。在供水路4的中途，设有为了开始或停止供水而被开闭的供水阀11。
排水路5与外筒3的下端部、例如正面壁3C的第一部3G的下端部连接。外筒3内的水从排水路5排出至机外。在排水路5的中途，设有为了开始或停止排水而被开闭的排水阀12。
排水过滤器6设置于排水路5中比排水阀12更靠近外筒3的上游部。排水过滤器6的前端露出至箱体2的前表面2A，因而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比外筒3小一圈。洗涤筒7具有：与外筒3的圆周壁3A同轴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，外筒3内的水经由贯通孔7D在外筒3与洗涤筒7之间往来。由此，外筒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，设有沿轴线J向后侧Y2延伸的支承轴13。支承轴13的后端部穿过外筒3的背面壁3B的贯通孔3F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从后侧Y2与外筒3的出入口3J和箱体2的开口2B对置并 连通。出入口3J和出入口7E与开口2B一起通过门10被一并开闭。洗干一体机1的使用者经由敞开的开口2B、出入口3J以及出入口7E，向洗涤筒7内投取洗涤物L。
马达8在箱体2内配置于外筒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13连结。马达8所产生的驱动力传递至支持轴13，洗涤筒7随着支承轴13绕轴线J旋转。需要说明的是，可以在马达8与支承轴13之间设置将马达8的驱动力向支承轴13传递或切断的离合器机构(未图示)。
烘干部9包括循环路20、送风部21以及加热部22。循环路20为在箱体2内配置于外筒3的上侧Z1的流路。循环路20具有：沿前后方向Y延伸的中途部分20A、从中途部分20A的后端向下侧Z2延伸的后部分20B以及从中途部分20A的前端向下侧Z2延伸的前部分20C。在后部分20B的下端部的前端，形成有取出口20D。取出口20D与外筒3的背面壁3B的外周部3D中的高于上限水位的部分连接，从后侧Y2与外筒3内连通。在前部分20C的下端，形成有返回口20E。返回口20E与外筒3的正面壁3C的第二部3H的上端部连接，从上侧Z1与外筒3内连通。
送风部21是所谓的鼓风机，包括在循环路20内配置于靠近取出口20D的上游侧的区域的旋转叶片23和使旋转叶片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。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。
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。洗涤烘干运转包括清洗过程、漂洗过程、脱水过程以及烘干过程。
在清洗过程开始之前，向洗涤筒7内投入洗涤剂。在清洗过程中，控制部 24在关闭排水阀12的状态下，将供水阀11打开规定时间而向外筒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反复进行被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24打开排水阀12进行排水时，清洗过程结束。
在漂洗过程中，控制部24在关闭排水阀12的状态下将供水阀11打开规定时间向外筒3和洗涤筒7供水之后，通过马达8使洗涤筒7旋转。这样，由于上述的摔打被反复进行，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在打开排水阀12的状态下使洗涤筒7脱水旋转。通过由洗涤筒7的脱水旋转而产生的离心力，洗涤筒7内的洗涤物L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。不只是在漂洗过程之后，在清洗过程之后也可以实施脱水过程。
在烘干过程中，控制部24通过送风部21和加热部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。由于当异物附着并累积于加热部22的散热部22A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，烘干部9还包括过滤单元25、支路26以及注水阀27。以下，在对送风部21和循环路20进行详细说明之后，对过滤单元25、支路26以及注水阀27进行说明。
图2是从后侧Y2观察外筒3和烘干部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，固定于箱体2。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和烘干部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和连接壳体29与管道30的连接软管31。管道30包括主体32和罩33(参照图2)。
主体32具有弯曲壁32A和顶壁32B，弯曲壁32A以沿着外筒3的圆周壁3A的左上部分向左下侧下降的方式弯曲，顶壁32B呈向前侧Y1鼓出的近似半圆的板状并且从弯曲壁32A的右端向左侧X2延伸。在弯曲壁32A与顶壁32B之间，划分出随着临近右侧X1而在上下方向Z上变窄的下游空间32C。顶壁32B以随着临近左侧X2而下降的方式，相对于水平方向H倾斜地延伸。在顶壁32B设有向上侧Z1突出的圆筒状的上连结部32D。上连结部32D的内部空间处于从上侧Z1与下游空间32C连通的状态。下游空间32C和上连结部32D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具有侧壁32E，侧壁32E以从前侧Y1和左侧X2堵住下游空间32C的方式架设于弯曲壁32A和顶壁32B的端缘之间。
主体32具有从弯曲壁32A的后端向下侧Z2延伸的第一纵壁32F和从第一纵壁32F的下端向后侧Y2突出的横壁32G。第一纵壁32F的上端沿弯曲壁32A弯曲成圆弧状，第一纵壁32F的下端以随着临近左侧X2而下降的方式一边相对于水平方向H倾斜一边直线状延伸。横壁32G呈带状，沿着第一纵壁32F的下端一边相对于水平方向H倾斜一边延伸。侧壁32E的后端部配置于下游空间32C的后侧Y2，侧壁32E的后端部的下部分与第一纵壁32F和横壁32G各自的左端连接。
主体32具有将侧壁32E的后端部和横壁32G包边的在后视观察时呈L字形状的第二纵壁32H。在第二纵壁32H的下端部形成有一个或多个上述的取出口20D。在本实施方式中，形成有一个在上下方向Z上长的长孔状的取出口20D，其沿前后方向Y贯通第二纵壁32H。在第二纵壁32H设有将取出口20D包边并且向前侧Y1突出的筒状的下连结部32I。在外筒3的背面壁3B形成有与取出口20D相同形状的贯通孔3K。下连结部32I从后侧Y2插入贯通孔3K。由此，取出口20D与背面壁3B连接而与外筒3内连通。
主体32具有外壁32J，该外壁32J将第一纵壁32F的右缘和第二纵壁32H的左缘、下缘以及右缘连接包边并且向后侧Y2突出。外壁32J形成为后视观察时呈近似U字状，外壁32J的两个上端部分别与顶壁32B的后端部的左端和右端连接。在外壁32J中与顶壁32B的右端连接的上端部，形成有向前侧Y1凹陷的切口32JA。在外壁32J的外周面中靠前的区域，设有多个从该外周面突出的 第一卡定部32JB。螺钉B1(参照图2)插通形成于各个第一卡定部32JB的插通孔，组装至设置于外筒3的背面壁3B中对应位置的螺纹孔3L。由此，包括主体32的整个管道30被固定于外筒3。在主体32形成有被侧壁32E的后端部、横壁32G、顶壁32B以及外壁32J的右部分划分出的中途空间32K。中途空间32K是后视观察时呈大致矩形且在前后方向Y上薄的空间，从后侧Y2与第一纵壁32F邻接，从后侧Y2与下游空间32C连通。
主体32具有从第二纵壁32H向后侧Y2突出的纵分隔板32L和横分隔板32M。纵分隔板32L从左侧X2与中途空间32K邻接地配置，从顶壁32B的后端部向下侧Z2延伸，与取出口20D中的上侧Z1的边缘相连。在纵分隔板32L的中途部形成有贯通孔32N，其形成为在上下方向Z上尺寸长的长方形状。横分隔板32M配置于中途空间32K的下侧Z2且配置于取出口20D的侧Z1，架设于纵分隔板32L的中途部与外壁32J的右部分之间。横分隔板32M以随着临近左侧X2而下降的方式一边相对于水平方向H倾斜一边与顶壁32B和横壁32G大致平行地延伸。横分隔板32M的上表面部的左端与纵分隔板32L的贯通孔32N的下端相连。在横分隔板32M的中途部形成有将横分隔板32M在左右方向X上一分为二的狭缝32P。在狭缝32P内的第二纵壁32H的后表面部形成有螺纹孔32Q。
在主体32形成有由纵分隔板32L、横分隔板32M、顶壁32B以及外壁32J的右部分划分出的配置空间32R。配置空间32R是在后视观察时呈大致矩形且在前后方向Y上薄的空间，从后侧Y2与中途空间32K连通。配置空间32R中比横壁32G更靠上侧Z1的部分在后视观察时与中途空间32K的整个区域重叠。在配置空间32R配置有过滤单元25。在主体32形成有上游空间32S，该上游空间32S由纵分隔板32L中比贯通孔32N更靠下侧Z2的部分、横分隔板32M以及外壁32J的右部分和下部分划分而成。上游空间32S是后视观察时呈向下侧Z2鼓出的近似半圆形状的空间，隔着横分隔板32M位于配置空间32R的下侧Z2，从后侧Y2与取出口20D连通。
在主体32形成有由外壁32J的左部分和纵分隔板32L从左右方向X的两侧夹着并沿上下方向Z细长地延伸的纵空间32T。纵空间32T被第二纵壁32H的左端部从前侧Y1堵住，被顶壁32B的左端部从上侧Z1堵住。纵空间32T的下 端从左侧X2与上游空间32S连通。主体32包括架设在纵分隔板32L中的比贯通孔32N更靠上侧Z1的部分与外壁32J的左部分之间的隔断板32U。纵空间32T被位于其中途的隔断板32U二分为隔断板32U的下侧Z2的下区域和隔断板32U的上侧Z1的上区域。贯通孔32N从右侧X1与隔断板32U的下区域连通。
罩33(参照图2)具有后视观察时与主体32的外壁32J和顶壁32B几乎一致的轮郭，形成为随着临近下侧Z2而宽度变窄的板状。在罩33设有从其外缘突出的多个卡定部33A(参照图2)。对应于卡定部33A，在主体32的外壁32J的外周面中靠后的区域，设有多个从该外周面突出的第二卡定部32JC。螺钉(未图示)插通形成于各个卡定部33A的插通孔，组装于设置在相应的第二卡定部32JC的后端面的螺纹孔32JD。由此，罩33从后侧Y2固定于主体32，完成管道30(参照图2)。
在完成的管道30中，设置于主体32的后表面侧的配置空间32R、上游空间32S以及纵空间32T被罩33从后侧Y2堵住。纵分隔板32L和隔断板32U各自的后端与罩33的前表面部接触。因此，隔着纵分隔板32L配置的配置空间32R和纵空间32T的下区域除了纵分隔板32L的贯通孔32N之外，都不连通。此外，在纵空间32T中，隔着隔断板32U配置的下区域和上区域被隔断。由于在横分隔板32M的后端与罩33的前表面部之间存在间隙Q(参照图12)，因此配置空间32R和上游空间32S经由该间隙Q连通。
连接软管31例如为橡胶制的圆筒，其内部空间向上侧Z1和下侧Z2敞开。在连接软管31的上端部与下端部之间，设有蛇腹部31A。连接软管31的下端部外嵌于管道30的上连结部32D。连接软管31的上端部与送风部21的壳体29连结。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。通过蛇腹部31A的弹性变形，能抑制洗涤烘干运转中外筒3的振动传递给送风部21。
图4是过滤单元25的后视图。后视观察时过滤单元25的整体形状形成为矩形，详细地说是平行四边形，该矩形具有以随着临近左侧X2而下降的方式相对于水平方向H倾斜的两边和沿上下方向Z大致垂直地延伸的另外两边。图5是过滤单元25的俯视图。过滤单元25形成为在前后方向Y上薄的箱状。

第一过滤构件41具有：框部41A，具有后视观察时近似矩形的轮郭；左右一对纵壁41B，从框部41A向前侧Y1突出；以及底壁41C，从框部41A的下端向前侧Y1突出。框部41A的上缘和下缘以随着临近左侧X2而下降的方式相对于水平方向H倾斜。框部41A的右缘和左缘沿上下方向Z大致垂直地延伸。框部41A的右缘的下端部以随着临近下侧Z2而向左侧X2偏离的方式弯曲。在框部41A的上缘设有向上侧Z1突出并且沿着该上缘向左右方向X延伸的肋状的上插入部41D。在后视观察时的框部41A的几乎整个区域，设有沿前后方向Y贯通框部41A的开口41E。框部41A具有纵切开口41E的一个或多个纵肋41F。在本实施方式中，沿左右方向X排列设置有两个纵肋41F，开口41E被这些纵肋41F均等地划分为沿左右方向X排列的三个小开口41EA。各个小开口41EA形成为具有纵长的长方形，严密地说形成为具有与框部41A的上缘和下缘平行的两边的平行四边形。在第一过滤构件41设有覆盖各小开口41EA的整个区域的烘干过滤器F1。本实施方式中的烘干过滤器F1是装配于框部41A的网眼片，但也可以是与框部41A形成为一体的网格。将烘干过滤器F1中沿上下左右延伸的后表面部称为纵面部F1A。在框部41A的后表面部中比开口41E更靠下侧Z2处，设有向后侧Y2突出并且沿开口41E的下端向左右方向X延伸的横肋41G。
一对纵壁41B包括右纵壁41BA和左纵壁41BB，右纵壁41BA从框部41A的右缘向前侧Y1突出并沿上下方向Z延伸，左纵壁41BB从框部41A的左缘向前侧Y1突出并沿上下方向Z延伸。右纵壁41BA的下端部沿着框部41A的右缘的下端部弯曲。右纵壁41BA的前端部构成在左右方向X上窄一圈并沿上下方向Z延伸的肋状的右插入部41BC。在作为一对纵壁41B中的一方的左纵壁41BB的下端部，形成有沿左右方向X贯通左纵壁41BB的释放孔41BD。左纵壁41BB中比释放孔41BD更靠上侧Z1的部分的前端部构成在左右方向X上窄一圈并沿上下方向Z延伸的肋状的左插入部41BE。
底壁41C架设于右纵壁41BA和左纵壁41BB的下端之间。底壁41C的上表面部41CA以随着临近左侧X2的释放孔41BD而下降的方式相对于水平方向H倾斜，与释放孔41BD相连。在左右方向X的底壁41C的中央部设有从底壁41C向下侧Z2突出的卡定部41CB。在卡定部41CB形成有沿前后方向Y贯通 卡定部41CB的插通孔41CC。
第二过滤构件42具有后视观察时具有大致矩形的轮郭的框部42A和从框部42A的上缘向后侧Y2突出的顶壁42B。框部42A的上缘和下缘以随着临近左侧X2而下降的方式相对于水平方向H倾斜。框部42A的右缘和左缘沿上下方向Z大致垂直地延伸。框部42A的右缘的下端部以随着临近下侧Z2而向左侧X2偏离的方式弯曲。在后视观察时的框部42A的几乎整个区域，设有沿前后方向Y贯通框部42A的开口42C。框部42A具有纵切开口42C的一个或多个纵肋42D。在本实施方式中，沿左右方向X排列设置有两个纵肋42D，开口42C被这些纵肋42D均等地划分为沿左右方向X排列的三个小开口42CA。各个小开口42CA形成为与第一过滤构件41的各个小开口41EA相同大小的长方形，严密地说形成为平行四边形。在第二过滤构件42设有覆盖各个小开口42CA的整个区域的烘干过滤器F2。本实施方式中的烘干过滤器F2是沿上下左右装配于框部42A的网眼片，但是也可以是与框部42A形成为一体的网格。将烘干过滤器F2中沿上下左右延伸的后表面部称为纵面部F2A。
以下，有时将第一过滤构件41的烘干过滤器F1和第二过滤构件42的烘干过滤器F2统称为“烘干过滤器F”。有时将烘干过滤器F1的纵面部F1A和烘干过滤器F2的纵面部F2A统称为“纵面部FA”。
在框部42A的后表面部中比开口42C更靠右侧X1处，设有沿着框部42A的右缘向上下方向Z延伸的一对右肋42E。在这些右肋42E之间形成有向上下方向Z延伸的右插入槽42F。在框部42A的后表面部中比开口42C更靠左侧X2处，设有沿着框部42A的左缘向上下方向Z延伸的一对左肋42G。在这些左肋42G之间形成有向上下方向Z延伸的左插入槽42H。
顶壁42B具有主体部42BA和延伸设置部42BB，主体部42BA呈在左右方向X上尺寸长的长方形板状，沿着框部42A的上缘向左下倾斜配置，延伸设置部42BB呈比主体部42BA短的长方形板状，从主体42BA的右端沿着水平方向H向右侧X1延伸。主体部42BA具有长方形板状的下部42BC和长方形板状的上部42BD，下部42BC在俯视时构成主体部42BA的整体轮郭的，上部42BD设置于下部42BC的上表面部，俯视时配置于下部42BC的轮郭的内侧。在下部42BC的下表面部的后端部，形成有向左右方向X延伸的上插入槽42BE(参照 后述的图14)。延伸设置部42BB具有长方形板状的下部42BF和长方形板状的上部42BG，下部42BF在俯视时构成延伸设置部42BB的整体轮郭，上部42BG设置于下部42BF的上表面部，俯视时配置于下部42BF的轮郭的内侧。下部42BF的左端与主体部42BA的下部42BC的右端相连，上部42BG的左端与主体部42BA的上部42BD的右端相连。在顶壁42B的上表面部，作为下部42BC和下部42BF的上表面部的一部分，形成有俯视时包围上部42BD和上部42BG的框状的外缘部42K。
在主体部42BA形成有多个同一形状且同一尺寸的供水口42J。各个供水口42J沿纵向也就是沿上下方向Z直线状地延伸并贯通下部42BC和上部42BD双方(参照后述的图9和图10)。各个供水口42J具有近似矩形的平截面，该平截面在上下方向Z上的供水口42J的任意位置均相同。供水口42J的平截面为供水口42J的流路面积。这些供水口42J包括：多个第一供水口42JA，分布在上部42BD的后端部的整个区域，沿左右方向X等间隔地排成一列；以及多个第二供水口42JB，分布在上部42BD的前端部的整个区域，沿左右方向X等间隔地排成一列。在本实施方式中，各设有12个第一供水口42JA和第二供水口42JB。上述的上插入槽42BE配置于第一供水口42JA的列与第二供水口42JB的列之间(参照图14)。
供水罩43具有在左右方向X上尺寸长且中空的主体部43A和从右侧X1与主体部43A连接的中空的连接部43B。主体部43A的下表面部43AA以随着临近左侧X2而下降的方式相对于水平方向H倾斜。主体部43A的内部空间43AB从几乎遍及下表面部43AA的整个区域地形成的开口43AC(参照图8)向下侧Z2敞开。连接部43B的下表面部43BA沿水平方向H延伸。连接部43B的内部空间43BB从几乎遍及下表面部43BA的整个区域地形成的开口43BC(图8参照)向下侧Z2敞开。连接部43B的开口43BC从右侧X1与主体部43A的开口43AC相连，连接部43B的内部空间43BB从右侧X1与主体部43A的内部空间43AB连通。在连接部43B的后表面部设有向后侧Y2延伸的管状的管部43BD。管部43BD的内部空间43BE从后侧Y2与连接部43B的内部空间43BB连通。主体部43A的内部空间43AB、连接部43B的内部空间43BB以及管部43BD的内部空间43BE成为一体，构成供水罩43内的流路43C。形成于管部43BD的 后端面并使内部空间43BE向后侧Y2敞开的圆形的开口构成流路43C的流入口43CA。流入口43CA的开口面积是流入口43CA的流路面积。
接着，对过滤单元25的组装进行说明。操作者通过将第一过滤构件41的右插入部41BC、左插入部41BE以及上插入部41D分别插入第二过滤构件42的右插入槽42F、左插入槽42H以及上插入槽42BE(参照图14)，从而将第一过滤构件41和第二过滤构件42组合起来。然后，操作者通过从上侧Z1将供水罩43覆盖于第二过滤构件42的顶壁42B，从而将供水罩43和第二过滤构件42组合起来。由此，完成过滤单元25。需要说明的是，也可以在组合供水罩43和第二过滤构件42之后，组合第一过滤构件41和第二过滤构件42。
图7是完成的过滤单元25的立体图。在完成的过滤单元25中，第一过滤构件41的框部41A配置于第二过滤构件42的框部42A的后侧Y2。由此，装配于框部41A的烘干过滤器F1配置为从后侧Y2与装配于框部42A的烘干过滤器F2重叠。如此一来，在相邻的烘干过滤器F1和烘干过滤器F2之间确保了空间S。第一过滤构件41的右纵壁41BA和左纵壁41BB从横向也就是从左右方向X的两侧夹着空间S。形成于左纵壁41BB的释放孔41BD从左侧X2与空间S连通，面向空间S的外部。第一过滤构件41的底壁41C与框部42A的下端连接，从下侧Z2堵住空间S。第二过滤构件42的顶壁42B的主体部42BA从上侧Z1堵住空间S。顶壁42B和从上侧Z1盖住顶壁42B的供水罩43构成供水部50。
图8是图4的A－A剖视图。供水罩43的下表面部中，将主体部43A的开口43AC和连接部43B的开口43BC包边的外缘部从上侧Z1与顶壁42B的上表面部的外缘部42K的整个区域接触(也参照图6)。顶壁42B的上部42BD和上部42BG从下侧Z2嵌入供水罩43的流路43C内。供水罩43内的流路43C从上侧Z1与形成于顶壁42B的所有供水口42J连接。
图9是图5的B－B剖视图。在供水罩43中的构成流路43C的一部分的主体部43A的内部空间43AB中，前后方向Y的宽度W大致固定(参照图8)，但是高度尺寸D随着临近左侧X2而变小。为了实现这样的高度尺寸D，主体部43A的顶壁43AD的上下方向Z的厚度配置成随着临近左侧X2而增加。供水口42J当中的后侧Y2的第一供水口42JA在前后方向Y和左右方向X上与第一过滤构件41的烘干过滤器F1的纵面部F1A配置于同一位置，并配置于纵面部F1A 的上侧Z1。由此，多个第一供水口42JA沿着对应的烘干过滤器F1的纵面部F1A在横向也就是左右方向X上排列，从上侧Z1面向纵面部F1A。
图10是图5的C－C剖视图。第二过滤构件42的烘干过滤器F2的纵面部F2A从前侧Y1面向烘干过滤器F1与烘干过滤器F2之间的空间S。供水口42J当中的前侧Y1的第二供水口42JB在前后方向Y和左右方向X上与烘干过滤器F2的纵面部F2A配置于同一位置，并配置于纵面部F2A的上侧Z1。由此，多个第二供水口42JB沿着对应的烘干过滤器F2的纵面部F2A横向排列，从上侧Z1面向纵面部F2A。这样，供水口42J像第一供水口42JA、第二供水口42JB那样与多个烘干过滤器F对应地设置多个。
图11是包括纵截面的管道30和过滤单元25的立体图。图11中，省略管道30的罩33的图示。过滤单元25从后侧Y2嵌入管道30的配置空间32R(也参照图3)。在第二过滤构件42的框部42A的前表面部中比烘干过滤器F2更靠下侧Z2处，设有向左右方向X延伸的横肋42L。在管道30的第二纵壁32H中从前侧Y1与框部42A对置的部分，设有向左右方向X延伸的横槽32HA。第一过滤构件41的底壁41C载置于管道30的横分隔板32M，横肋42L嵌入横槽32HA，由此，过滤单元25被定位在配置空间32R内。底壁41C的卡定部41CB嵌入横分隔板32M的狭缝32P中，螺钉B2穿过卡定部41CB的插通孔41CC而装配于狭缝32P的螺纹孔32Q(也参照图3和图6)。由此，配置空间32R内的过滤单元25固定于管道30。
在固定于管道30的过滤单元25的第一过滤构件41中，底壁41C、右纵壁41BA以及左纵壁41BB分别与管道30的横分隔板32M、外壁32J以及纵分隔板32L(参照图3)接触。此外，过滤单元25的供水罩43的主体部43A与管道30的顶壁32B接触。由此，过滤单元25占据管道30的配置空间32R的几乎整个区域，在管道30内位于下游空间32C和中途空间32K与上游空间32S之间。从循环路20整体来看，过滤单元25中的多个烘干过滤器F在循环路20内配置于比加热部22更靠取出口20D侧(参照图1)。在多个烘干过滤器F中，烘干过滤器F1配置于比烘干过滤器F2更靠取出口20D侧。供水罩43的连接部43B穿过外壁32J的切口32JA(参照图3)而配置于配置空间32R的右侧X1。形成于左纵壁41BB的释放孔41BD(参照图7)从右侧X1与纵分隔板32L的贯通 孔32N(参照图3)连通。
支路26从供水路4中的比供水阀11更靠近水龙头的上游部分支，与供水罩43的连接部43B的管部43BD连接。注水阀27设置于支路26(参照图1)。注水阀27为了将从供水路4流向支路26的水供给至管部43BD或停止该供给而被开闭。注水阀27的开闭由控制部24(参照图1)控制。
烘干过程中，如上所述通过送风部21和加热部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，一边在其中途的后部分20B上升，一边前往送风部21(参照图1的粗虚线的箭头)。图12是包括纵截面的外筒3和烘干部9的主要部分立体图。参照图11和图12，在构成后部分20B的管道30内，热风如粗虚线的箭头所示，从取出口20D经由上游空间32S上升，按顺序向前侧Y1穿过过滤单元25的烘干过滤器F1和烘干过滤器F2。然后，该热风经由中途空间32K到达下游空间32C，在连接软管31的内部上升并流入送风部21的壳体29内(也参照图2)。这样，烘干过滤器F1和烘干过滤器F2以在循环路20内的空气的流向(各图的粗虚线的箭头的方向)上重叠的方式配置。
烘干过滤器F1的纵面部F1A和烘干过滤器F2的纵面部F2A以朝向循环路20的上游侧的方式配置，从循环路20内的热风中捕获异物T(参照图11)。随着烘干过程的进行，大量的异物T被捕获并存留于纵面部F1A和纵面部F2A。由此，能抑制异物T附着于在循环路20内比这些烘干过滤器F更从取出口20D向下游侧偏离地设置的加热部22。特别是，由于未被纵面部F1A捕获的异物T会被纵面部F2A捕获，因此，能降低异物T流出而附着于加热部22的风险。进而，烘干过滤器F1与烘干过滤器F2之间的空间S被一对纵壁41B从横向夹着，被底壁41C从下侧Z2堵住，被供水部50从上侧Z1堵住。由此，能防止穿过烘干过滤器F1到达空间S的空气不到达下一个烘干过滤器F2而漏出到空间S外部。因此，由于流过循环路20内的空气可靠地依次通过多个烘干过滤器F，因而能通过这些烘干过滤器F，从流过循环路20内的空气中捕获更多的异物T。
图13是管道30和过滤单元25的立体图。在图13中，省略管道30的罩33的图示。在位于管道30内的左端的纵空间32T的下区域设有将纵分隔板32L的贯通孔32N开闭的门51。门51呈在上下方向Z上尺寸长的长方形板状，经由 穿过其上端的转动轴52支承于纵分隔板32L，能绕转动轴52向左右方向X转动。图13的门51位于沿着纵分隔板32L从左侧X2关闭贯通孔32N的关闭位置。即使在烘干过程中从取出口20D流入管道30的上游空间32S的空气到达纵空间32T的下区域，门51也会被该空气向关闭位置施力。因此，抑制了上游空间32S的空气不穿过烘干过滤器F1而是穿过贯通孔32N和过滤单元25的释放孔41BD(图7参照)流向烘干过滤器F2侧的情况。也就是说，上游空间32S的空气以必定会穿过烘干过滤器F1的方式流动。
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27。需要说明的是，供水阀11也可以设置在供水路4中的比支路26的分支位置更靠近水龙头的上游侧，这种情况下，控制部24将供水阀11和注水阀27双方打开。来自水龙头的水经由供水路4和支路26，从供水罩43的管部43BD的流入口43CA流入流路43C内。
流入流路43C内的水从流路43C内流出至各个供水口42J并从各个供水口42J喷射。如粗虚线的箭头所示，从供水口42J当中的第一供水口42JA喷出的水从上侧Z1淋至烘干过滤器F1的纵面部F1A，沿着纵面部F1A流下。附着于纵面部F1A的异物T通过在纵面部F1A上流下的水而从纵面部F1A剥离，直接落下至管道30的上游空间32S，到达取出口20D。在烘干过滤器F1的周边设有沿水、异物T落下的方向延伸的纵肋41F，因而异物T会以不挂到纵肋41F上的方式顺利地落下。在管道30中划分出上游空间32S的外壁32J等处，设有朝向取出口20D倾斜的引导部30A，引导部30A将异物T、水引向取出口20D。到达取出口20D的异物T从取出口20D落下至外筒3内，存留于外筒3内。从各个第一供水口42JA淋至纵面部F1A的水也与异物T一样，从管道30落下至外筒3内，存留于外筒3内。
最靠近取出口20D的烘干过滤器F1的纵面部FA1直接露出至构成循环路20的上流空间32S内。因此，当从第一供水口42JA向纵面部FA1供水时，附着于纵面部FA1的异物T会在从纵面部FA1剥离之后迅速在循环路20内落下，从取出口20D到达外筒3内。在管道30中将取出口20D包边的下连结部32I从后侧Y2插入外筒3的背面壁3B的贯通孔3K内，下连结部32I的前端从背面壁3B的前表面部露出至外筒3内(参照图12)。也就是说，由于从取出口 20D到外筒3内之间不存在阶梯等障碍物，因而异物T能以不在中途被挂住的方式从取出口20D到达外筒3内。
图14是管道30和过滤单元25的立体图。图14中，省略了管道30的罩33和第一过滤构件41的图示，第二过滤构件42的烘干过滤器F2露出进行图示。如粗虚线的箭头所示，从供水口42J当中的第二供水口42JB喷出的水从上侧Z1淋至烘干过滤器F2的纵面部F2A，沿着纵面部F2A流下。附着于纵面部F2A的异物T通过在纵面部F2A上流下的水而从纵面部F2A剥离，在烘干过滤器F1与烘干过滤器F2之间的空间S中落下，置于第一过滤构件41的底壁41C的上表面部41CA。由于在烘干过滤器F2的周边设有沿水、异物T落下的方向延伸的纵肋42D，因而异物T会以不挂到纵肋42D上的方式顺利落下。
空间S被烘干过滤器F1和烘干过滤器F2从前后方向Y夹住，被右纵壁41BA和左纵壁41BB从横向夹住，被底壁41C从下侧Z2堵住(也参照图7)。因此，底壁41C的上表面部41CA上的水和异物T沿上表面部41CA的倾斜滑落，必定会前往左侧X2而到达第一过滤构件41的释放孔41BD和纵分隔板32L的贯通孔32N。也就是说，底壁41C的上表面部41CA上的水和异物T的目的地被定为释放孔41BD。到达贯通孔32N的水和异物T从右侧X1推压门51。由此，如图14所示，门51从目前的关闭位置向左侧X2转动而打开释放孔41BD和贯通孔32N，因此上表面部41CA上的水和异物T会穿过释放孔41BD和贯通孔32N而去到空间S的外部，在管道30的纵空间32T的下区域中落下，到达取出口20D。到达取出口20D的异物T和水从取出口20D落下并存留于外筒3内。在异物T、水穿过释放孔41BD和贯通孔32N之后，门51会因自重或施力构件(未图示)的施加力等而返回到关闭位置。
当注水阀27打开后经过规定时间时，控制部24通过关闭注水阀27来停止向供水部50供水并打开排水阀12。需要说明的是，在注水阀27打开的状态下，排水阀12也可以始终处于打开状态。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。也就是说，异物T在外筒3排水时被从外筒3内去除。流入排水路5的异物T被排水过滤器6(参照图1)捕获。当使用者在适当的时刻卸下排水过滤器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，洗干一体机1中，在规定的时刻，供水部50从上侧Z1向多个 烘干过滤器F的纵面部FA供水。也就是说，洗干一体机1具有自动维护烘干过滤器F的功能，因而不需要使用者卸下烘干过滤器F进行维护的作业。因此，能实现对烘干过滤器F的维护性的提高。特别是，过滤单元25中，不只是被最靠近取出口20D的烘干过滤器F1的纵面部F1A捕获的异物T，被隔着空间S与烘干过滤器F1重叠的烘干过滤器F2的纵面部F2A捕获的异物T也通过供水部50的供水被送入外筒3内。因此，使用者不需要卸下烘干过滤器F来从空间S去除异物T，因而能进一步实现对烘干过滤器F的维护性的提高。
由于烘干过滤器F可以是不可拆卸的，因此与拆装式烘干过滤器相比能实现构造简化、成本降低。此外，在拆装式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则能避免忘记维护而导致的性能降低。此外，由于能将拆装式烘干过滤器的情况下所需的配置空间活用于其他用途，因而能通过例如使加热部22、旋转叶片23大型化来实现性能的提高。
供水部50的供水口42J以沿着对应的烘干过滤器F的纵面部FA横向排列的方式设有多个，各个供水口42J通过沿纵向直线状地延伸，从而引导流过供水口42J的水笔直落下(参照图13和图14)。因此，从横向排列的多个供水口42J分别笔直落下的水从上侧Z1淋至各个烘干过滤器F的纵面部FA，能可靠地剥离纵面部FA上的左右方向X上的较大范围内的异物T。特别是，在排成一列的多个供水口42J中，相邻的供水口42J之间以不相连的方式分离配置，因此容易控制来自供水口42J的水的喷射方向。
流入口43CA的流路面积设定为大于所有(在本实施方式中为24个)的供水口42J的流路面积的总和。这种情况下，来自供水口42J的水的流出量小于从流入口43CA流向流路43C的水的流入量。由此，通过在流路43C内暂时拦截从流入口43CA流入流路43C的水，能使该水遍及流路43C的整个区域。由此，能使流路43C内的水从各个供水口42J以相同的势头、相同的时刻流出。因此，能从各个烘干过滤器F的纵面部FA均匀并且同时剥离异物T。因此，能进一步实现对烘干过滤器F的维护性的提高。
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形。
例如，在上述实施方式中，烘干过滤器F为烘干过滤器F1和烘干过滤器F2这两个，但是也可以将三个以上的烘干过滤器F重叠配置。这种情况下，与上述的烘干过滤器F2相同，为了去除异物T，水从上侧Z1淋至最接近管道30的取出口20D的烘干过滤器F1之外的各个烘干过滤器F的纵面部FA。多个烘干过滤器F中，纵面部FA以朝向循环路20的取出口20D侧也就是上游侧的方式纵向配置，而这些纵面部FA既可以平行地配置，也可以不平行地配置。此外，各个纵面部FA既可以沿垂直方向配置，也可以相对于垂直方向倾斜地配置。
洗干一体机1中，可以省略排水过滤器6。这种情况下，由各个烘干过滤器F捕获并流到外筒3的异物T在外筒3排水时穿过排水路5(参照图1)排出到机外。
作为烘干过滤器F的自动维护的一环，控制部24也可以在停止从供水部50向烘干过滤器F供水之后，通过送风部21使外筒3内的空气循环。由此，此前为了去除异物T而被喷水打湿的烘干过滤器F通过被从外筒3流入循环路20的空气吹拂而烘干。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F的烘干。这样一来，由于使用者可以不将烘干过滤器F烘干，因而能实现对烘干过滤器F的维护性的进一步提高。
上述实施方式中的滚筒式洗干一体机1中，也可以使轴线J向水平方向H倾斜地配置洗涤筒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。
