Description

除湿装置及烘干机 技术领域
本发明涉及除湿装置及包括该除湿装置的烘干机。
背景技术
下述专利文献1所记载的空气处理装置包括柜体和设于柜体的里侧的吸入罩。在吸入罩设有吸入口。在柜体设有：与吸入口连通的风路；配置于风路内的送风机、过滤器以及集尘单元；以及与风路连通的吹出口。当送风机工作时，空气处理装置的周边的空气从吸入口被吸入至风路内，经过过滤器和集尘单元。
过滤器从经过过滤器的空气中去除油烟、水蒸气、臭气。集尘单元包括隔开间隙地对置配置的放电电极和对置电极。无法由过滤器去除的小的油烟、水蒸气由于在放电电极与对置电极之间产生的放电而被带电并被收集。流入风路内的空气像这样经过过滤器和集尘单元而被净化，然后从吹出口吹出到空气处理装置之外。
在使用专利文献1的集尘单元进行除湿的情况下，可以意料到由于风路的内外的温度差而在风路内产生结露。当由于由结露产生的水滴而使放电电极与对置电极之间的间隙变小时，在放电电极与对置电极之间不易放电，因此除湿性能降低。

发明内容
发明所要解决的问题
本发明是鉴于该背景而完成的，其目的在于提供一种能抑制在由于放电电极的放电而使水分带电并进行收集的结构中由结露引起的除湿性能的降低的除湿装置及包括该除湿装置的烘干机。
用于解决问题的方案
本发明是一种除湿装置，包括：容纳筒，容纳烘干对象物；管道，使空气从所述容纳筒流出；放电电极，配置于所述管道内并进行放电；以及对置电极，在所述管道内与所述放电电极以隔开间隙的方式对置，且在所述管道内收集因所述放电电极的放电而带电了的水分，其中，在所述管道设有使所述管道的内部空间与外部空气连通的开口。
此外，本发明的特征在于，所述除湿装置还包括：支承部，支承所述放电电极，所述支承部的一部分从所述开口露出于所述管道外。
此外，本发明的特征在于，在所述支承部中配置于所述开口内的部分与所述管道中的所述开口的边缘之间设有间隙。
此外，本发明的特征在于，所述开口包括：导入口，将外部空气导入至所述管道内；以及排出口，将所述管道内的空气排出至所述管道外。
此外，本发明是一种烘干机，所述管道是通过使空气从所述容纳筒流出后流入所述容纳筒来使其循环的循环路，所述烘干机包括：所述除湿装置；送风部，使空气以在所述容纳筒与所述管道之间循环的方式流动；以及加热部，对从所述管道流入所述容纳筒的空气进行加热。
发明效果
根据本发明，除湿装置使从容纳烘干对象物的容纳筒流出至管道中的空气中所含的水分因放电电极的放电而带电并由对置电极收集，由此对该空气进行除湿。在管道设有使管道的内部空间与外部空气连通的开口。由此，外部空气经过开口出入于管道的内部，从而管道的内外的温度差变小，因此能防止管道内的结露。因此，能抑制由结露引起的除湿装置的除湿性能的降低。
此外，根据本发明，在除湿装置中，支承放电电极的支承部的一部分从开口露出于管道外。由此，管道内的放电电极的温度与管道外的外部空气的温度之差变小，因此能防止放电电极的结露。因此，能防止由于由结露产生的水滴 而使放电电极与对置电极之间的间隙变小，并将该间隙维持为规定以上的大小，因此能使放电电极的放电稳定。因此，能够进一步抑制由结露引起的除湿装置的除湿性能的降低。
此外，根据本发明，在支承部中配置于开口内的部分与管道中的开口的边缘之间设有间隙。由此，在支承部中配置于开口内的部分暴露于流过周围的间隙的外部空气中，由此支承部和放电电极与外部空气的温度差变小，因此能防止支承部和放电电极的结露。此外，通过该间隙，支承部与管道被分离并绝缘，因此能防止附着于管道的水分移动至支承部，也能防止支承部与管道之间的短路。
此外，根据本发明，开口包括：导入口，将外部空气导入至管道内；以及排出口，将管道内的空气排出至管道外。由此，外部空气从导入口被导入至管道内，管道内的空气从排出口被排出至管道外，由此管道的内外的温度差变小，因此能防止管道内的结露。因此，能抑制由结露引起的除湿装置的除湿性能的降低。
此外，根据本发明，在包括如上所述的除湿装置并使空气在容纳筒与管道之间循环的烘干机中，如上所述，能抑制由结露引起的除湿装置的除湿性能的降低。由此，在通过加热部对由除湿装置进行了除湿后的空气进行加热后返回至容纳筒而再次用于烘干对象物的烘干时，能利用该空气使容纳筒内的烘干对象物高效地烘干。

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是本发明的烘干机的一个实施方式的洗干一体机1的示意性纵剖右视图。将图1的与纸面正交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方X1，将图1的纸面的表侧称为右方X2。前后方向Y当中，将图1中的左侧称为前方Y1，将图1中的右侧称为后方Y2。上下方向Z当中，将上侧称为上方Z1，将下侧称为下方Z2。左右方向X和前后方向Y包括在横向中。横向既可以是水平方向H，也可以是相对于水平方向H稍微倾斜的大致水平方向。
在本实施方式中，作为洗干一体机1，以滚筒式的洗干一体机为主要对象，但洗干一体机1也可以是立式的洗干一体机。此外，本发明还以省略了洗涤功能而仅执行烘干运转的烘干机为对象。此外，在本实施方式中，洗干一体机1的烘干对象物是衣物等洗涤物L，但也可以是鞋、餐具等。烘干对象物为餐具的 烘干机的一个例子是餐具洗干一体机。
洗干一体机1包括：箱体2；容纳筒5，配置于箱体2内，包括水筒3和旋转筒4，容纳洗涤物L；供水路6和排水路7，与水筒3连接；马达8，使旋转筒4旋转；以及烘干单元9，将洗涤物L烘干。
箱体2形成为箱状。箱体2的前表面2A例如是垂直面。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。
水筒3由从箱体2的底壁2C向上方Z1延伸的减振器11支承，由弹簧(未图示)悬吊。由此，包括水筒3的整个容纳筒5被弹性支承。水筒3具有：圆筒状的圆周壁3A，以沿水平方向H在前后方向Y上延伸的轴线J为中心；圆盘状的背面壁3B，从后方Y2堵住圆周壁3A的中空部分；以及环状的正面壁3C，与圆周壁3A的前端缘相连。
在背面壁3B的中心形成有沿轴线J在前后方向Y上贯通背面壁3B的贯通孔3D。正面壁3C具有：圆环状的第一部3E，从圆周壁3A的前端缘向轴线J侧突出；圆筒状的第二部3F，从第一部3E的内周缘向前方Y1突出；以及圆环状的第三部3G，从第二部3F的前端缘向轴线J侧突出。在第三部3G的内侧形成有从前方Y1与圆周壁3A的中空部分连通的出入口3H。出入口3H处于从后方Y2与箱体2的开口2B对置并连通的状态。
旋转筒4是具有与轴线J一致的中心轴线的圆筒体，比水筒3小一圈。在本实施方式中，旋转筒4以中心轴线沿水平方向H的方式在水筒3内水平地配置，但也可以以中心轴线相对于水平方向H倾斜的方式倾斜地配置。旋转筒4具有：圆筒状的圆周壁4A，与水筒3的圆周壁3A同轴地配置；圆盘状的背面壁4B，从后方Y2堵住圆周壁4A的中空部分；以及圆环状的环状壁4C，从圆周壁4A的前端缘向轴线J侧突出。在圆周壁4A和背面壁4B形成有多个贯通孔4D。
在旋转筒4的背面壁4B的中心设有沿轴线J向后方Y2延伸的支承轴12。支承轴12的后端部穿过水筒3的背面壁3B的贯通孔3D而配置于比背面壁3B靠后方Y2处。
在环状壁4C的内侧形成有从前方Y1与圆周壁4A的中空部分连通的出入 口4E。出入口4E处于从后方Y2与水筒3的出入口3H及箱体2的开口2B对置并连通的状态。出入口3H和出入口4E与开口2B一起由门10统一开闭。洗干一体机1的用户经由敞开的开口2B、出入口3H以及出入口4E使洗涤物L出入于旋转筒4内。在门10上设有在门10关闭了开口2B、出入口3H以及出入口4E时与水筒3的正面壁3C的第三部3G紧贴的衬垫13。
供水路6具有与水龙头(未图示)连接的一端(未图示)和在箱体2内与水筒3的正面壁3C的第二部3F的例如上部连接的另一端，在该另一端设有从上方Z1面向水筒3内的供水口6A。供水时，来自水龙头的自来水经过供水路6从供水口6A供给至水筒3内。在水筒3内蓄有自来水或在自来水中溶解有洗涤剂的洗涤剂水。以下，有时将自来水和洗涤剂水简称为“水”。水筒3内的水经由旋转筒4的贯通孔4D在水筒3与旋转筒4之间往来。因此，水筒3内的水位与旋转筒4内的水位一致。
洗干一体机1包括：水位检测部14，检测水筒3内的水位；以及可开闭的供水阀15，设于供水路6的中途。作为水位检测部14，可以采用各种水位传感器。本实施方式中的水位检测部14是内置隔膜(未图示)的压电式传感器，经由软管16与水筒3连接。水位检测部14通过隔膜来测定随着水筒3内的水位的变化而变动的软管16内的压力，由此检测水筒3内的水位。
打开状态的供水阀15通过打开供水路6来允许向水筒3即容纳筒5的供水。关闭状态的供水阀15通过关闭供水路6来停止向容纳筒5的供水。
排水路7与水筒3的下端部例如圆周壁3A的下端部连接。水筒3内的水从排水路7被排出箱体2之外即机外。洗干一体机1包括设于排水路7的中途的可开闭的排水阀17。打开状态的排水阀17通过打开排水路7来允许水筒3的排水。关闭状态的排水阀17通过关闭排水路7来停止排水。
马达8在箱体2内配置于水筒3的背面壁3B的后方Y2。作为马达8的一个例子，可以采用DD(Direct Drive：直驱)马达。马达8与设于旋转筒4的支承轴12连结。马达8所产生的转矩被传递至支承轴12，旋转筒4随着支承轴12绕轴线J旋转。需要说明的是，也可以在马达8与支承轴12之间设置将马达8的转矩向支承轴12传递或切断的离合机构(未图示)。
烘干单元9包括：循环路20和送风部21，用于使水筒3内的空气循环；加热部22，加热循环的空气；以及除湿设备23，对流过循环路20内的空气进行除湿。
循环路20是在箱体2内例如配置于水筒3的上方Z1的管道。循环路20具有：中途部分20A，沿前后方向Y延伸；后部分20B，从中途部分20A的后端向下方Z2延伸后向前方Y1弯折；以及前部分20C，从中途部分20A的前端向下方Z2延伸。在后部分20B的下端部的前端形成有流出口20D。流出口20D与水筒3的背面壁3B的下部连接，从后方Y2与水筒3内连通。在前部分20C的下端形成有流入口20E。流入口20E与水筒3的正面壁3C的第二部3F的上端部连接，从上方Z1与水筒3内连通。
送风部21是所谓的鼓风机，包括配置于循环路20的中途部分20A内的旋转叶片21A和使旋转叶片21A旋转的马达(未图示)。当旋转叶片21A旋转时，如粗虚线箭头所示，容纳筒5内的空气即水筒3内和旋转筒4内的空气经过流出口20D从容纳筒5流出至循环路20内，然后经过流入口20E流入容纳筒5内。由此，空气以在容纳筒5与循环路20之间循环的方式流动。在该情况下的循环路20也可以是即使不取入外部空气即洗干一体机1的外部的空气也成立的完全内部循环路径。
加热部22是热泵中的热交换器或普通的加热器等，至少一部分设于循环路20内。加热部22中的设于循环路20内的部分具有散热部22A。在本实施方式中，散热部22A在循环路20内配置于比送风部21的旋转叶片21A靠近流入口20E的下游侧，但也可以配置于比旋转叶片21A远离流入口20E的上游侧。
当加热部22工作时，散热部22A变为高温，因此流过循环路20内的空气在经过散热部22A周围时会被加热而成为热风，然后流入容纳筒5。像这样，加热部22对从循环路20向容纳筒5流入的空气进行加热。
除湿设备23包括：带电部24，使流过循环路20内的空气中所含的水分带电；以及收集部26，收集通过带电部24而被带电了的水分。带电部24和收集部25在循环路20内配置于空气的流动方向上的比送风部21和加热部22靠上游侧的区域。以下，有时基于上述的左右方向X、前后方向Y以及上下方向Z来确定带电部24和收集部25各自的朝向。但是，带电部24和收集部25各自 的朝向可以任意变更，例如，对于各个带电部24和收集部25，既可以将左右方向X的朝向视为前后方向Y的朝向，也可以将前后方向Y的朝向视为左右方向X的朝向。
图2是带电部24的右视图，图3是图2的A－A向视剖视图。带电部24包括：树脂制且中空的壳体30；多个第一电极31，配置于壳体30内；以及第二电极32，在壳体30内配置于相邻的第一电极31之间。
壳体30的一个例子是由沿上下方向Z延伸的四个纵壁30A构成的长方体，由这些纵壁30A包围的空间是壳体30的内部空间30B。在壳体30形成有被四个纵壁30A的下端包边的矩形的入口30C和被四个纵壁30A的上端包边的矩形的出口30D。壳体30的上端部配置得更宽，由此，出口30D在左右方向X和前后方向Y上比内部空间30B大。
内部空间30B从入口30C向下方Z2敞开，从出口30D向上方Z1敞开。壳体30构成循环路20、详细而言后部分20B中的沿上下方向Z延伸的部分的一部分(参照图1)。因此，壳体30的内部空间30B、入口30C以及出口30D构成循环路20的内部空间中的沿上下方向Z延伸的区域的一部分。在本实施方式中，流过循环路20内的空气在壳体30内从入口30C前往出口30D而上升(参照粗虚线箭头)。
在四个纵壁30A中，将左方X1的纵壁30A称为左纵壁30AA，将右方X2的纵壁30A称为右纵壁30AB，将前方Y1的纵壁30A称为前纵壁30AC，将后方Y2的纵壁30A称为后纵壁30AD(也参照图4)。左纵壁30AA与右纵壁30AB在左右方向X上相互对置地配置，配置为左右对称或大致左右对称。前纵壁30AC与后纵壁30AD在前后方向Y上相互对置地配置。左纵壁30AA和右纵壁30AB与前纵壁30AC和后纵壁30AD正交地配置。
在左纵壁30AA和右纵壁30AB各自的前后方向Y的中央设有沿左右方向X贯通这些纵壁30A的贯通孔即开口30E。开口30E包括：导入口30EA，逐一设于左纵壁30AA和右纵壁30AB各自的上端部；以及排出口30EB，逐一设于左纵壁30AA和右纵壁30AB各自的下端部。在左纵壁30AA中，导入口30EA是在从出口30D连续的状态下将左纵壁30AA的上端部向下方Z2切口出的U字形的缺口，排出口30EB是在从入口30C连续的状态下将左纵壁30AA的下端部 向上方Z1切口出的倒U字形的缺口。右纵壁30AB的导入口30EA和排出口30EB也同样地配置(参照图4)。
这些开口30E使壳体30的内部空间30B与外部空气、即循环路20的外部的空气连通。特别是，导入口30EA将外部空气导入到壳体30内、即循环路20内(参照图3的单点划线的箭头)，排出口30EB将壳体30内的空气排出至壳体30之外、即循环路20之外(参照图3的双点划线的箭头)。与流过壳体30内的空气相比，外部空气的温度低。此外，在洗干一体机1的箱体2，除了上述的开口2B(参照图1)以外，还设有使箱体2的内外连通的通气口(未图示)，因此洗干一体机1的外部的外部空气经过该通气口流入箱体2内，由此也存在于循环路20的周边。
在左纵壁30AA的左表面的上下方向Z上的大致中央部设有向左方X1突出的突出部30F。在右纵壁30AB的右表面的上下方向Z上的大致中央部设有向右方X2突出的突出部30G。突出部30F和突出部30G分别配置为沿左右方向X延伸的圆柱状，设有一个或多个。在本实施方式中，突出部30F和突出部30G分别以在上下方向Z上排列的方式各设置两个。
在后纵壁30AD的后表面的下端部设有沿左右方向X延伸的中空的引导箱(guide box)30H(也参照图5)。引导箱30H的内部空间30J处于从后方Y2与壳体30的内部空间30B连通的状态。在引导箱30H中的从下方Z2划分出内部空间的底面30I是随着趋向左方X1而逐渐下降的倾斜面，在其下端形成有排水口30J(参照图6)。在引导箱30H的下表面设有以包围排水口30J的状态向下方Z2突出的圆筒状的连结部30K(参照图6)。
第一电极31是在左右方向X上薄的板状的对置电极，例如由不锈钢或铝形成，由此具有导电性。在本实施方式中，作为一个例子，四片第一电极31在壳体30的内部空间30B中以在左右方向X上等间隔地排列的方式配置。
带电部24包括保持这些第一电极31的金属制的座体33。座体33架设于左纵壁30AA的导入口30EA处的U字形的缘30L的下端与右纵壁30AB的导入口30EA处的U字形的边缘30M的下端之间。座体33的左端部形成为向上方Z1延伸后向左方X1弯折的L字形，处于卡合于边缘30L的下端的状态。座体33的右端部形成为向上方Z1延伸后向右方X2弯折的L字形，处于卡合于边缘 30M的下端的状态。由此，座体33相对于壳体30被定位。各第一电极31的上端与座体33连结。
各第一电极31中的壳体30的入口30C侧的下端缘31A以朝着引导箱30H逐渐下降的方式直线状地倾斜(参照图2)。在壳体30内设有从引导箱30H的底面30I向前上侧倾斜地延伸的斜坡30N，各第一电极31的下端缘31A中的后方Y2的下端部配置于斜坡30N的正上方(参照图2)。
第二电极32是由金属丝构成的放电电极，例如由钨形成，由此具有导电性，具有与第一电极31相反的极性。第二电极32逐一配置于相邻的第一电极31之间。处于各第一电极31相对于相邻的第二电极32隔开例如10mm左右的间隙V并对置的状态。
带电部24包括支承这些第二电极32的金属制的支承部34。支承部34存在上下一对。一对支承部34包括上方Z1的上支承部35和下方Z2的下支承部36。
上支承部35包括：框状的主体部35A，配置于壳体30的内部空间30B的上端部；以及左右一对延伸设置部35B，作为上支承部35的一部分从主体部35A向左右方向X的两侧延伸。各个延伸设置部35B包括：内侧部分35BA，与主体部35A连接并在壳体30内沿左右方向X水平地延伸；外侧部分35BB，配置于壳体30外并沿左右方向X水平地延伸；以及倾斜部分35BC，从外侧部分35BB向斜下侧倾斜地延伸并与内侧部分35BA连接。
在左方X1的延伸设置部35B中，倾斜部分35BC配置于壳体30的左纵壁30AA的导入口30EA内，外侧部分35BB通过从导入口30EA向左方X1伸出而露出于壳体30外。在倾斜部分35BC与导入口30EA的边缘30L之间设有间隙，因此包括倾斜部分35BC的延伸设置部35B整体不与边缘30L接触(也参照图4)。外侧部分35BB的左端部也可以弯折而向下方Z2延伸(参照图12)。
在右方X2的延伸设置部35B中，倾斜部分35BC配置于壳体30的右纵壁30AB的导入口30EA内，外侧部分35BB通过从导入口30EA向右方X2伸出而露出于壳体30外。在倾斜部分35BC与导入口30EA的边缘30M之间设有间隙，因此包括倾斜部分35BC的延伸设置部35B整体不与边缘30M接触(也参照图4)。外侧部分35BB的右端部也可以弯折而向下方Z2延伸(参照图12)。
下支承部36包括：框状的主体部36A，配置于壳体30的内部空间30B的下端部；以及左右一对延伸设置部36B，作为上支承部35的一部分从主体部36A向左右方向X的两侧延伸。各个延伸设置部36B包括：内侧部分36BA，与主体部36A连接并在壳体30内沿左右方向X水平地延伸；外侧部分36BB，配置于壳体30外并沿左右方向X水平地延伸；以及倾斜部分36BC，从外侧部分36BB向斜下侧倾斜地延伸并与内侧部分36BA连接。
在左方X1的延伸设置部36B中，倾斜部分36BC配置于壳体30的左纵壁30AA的排出口30EB内，外侧部分36BB通过从排出口30EB向左方X1伸出而露出于壳体30外。在倾斜部分36BC与左纵壁30AA的排出口30EB处的倒U字形的边缘30P之间设有间隙，因此包括倾斜部分36BC的延伸设置部36B整体不与边缘30P接触。
在右方X2的延伸设置部36B中，倾斜部分36BC配置于壳体30的右纵壁30AB的排出口30EB内，外侧部分36BB通过从排出口30EB向右方X2伸出而露出于壳体30外。在倾斜部分36BC与左纵壁30AA的排出口30EB处的倒U字形的边缘30Q之间设有间隙，因此包括倾斜部分36BC的延伸设置部36B整体不与边缘30Q接触(也参照图4)。
带电部24也可以包括金属制的连结部37，该连结部37将在上支承部35和下支承部36中在左右方向X上位于同侧的外侧部分35BB与外侧部分36BB彼此连结。连结部37是在上下方向Z细长的轨道状，左右存在一对。
左方X1的连结部37架设于上支承部35的左方X1的外侧部分35BB与下支承部36的左方X1的外侧部分36BB之间。左方X1的连结部37通过从左方X1与壳体30的左纵壁30AA的突出部30F接触而在左右方向X上被定位。右方X2的连结部37架设于上支承部35的右方X2的外侧部分35BB与下支承部36的右方X2的外侧部分36BB之间。右方X2的连结部37通过从右方X2与壳体30的右纵壁30AB的突出部30G接触而在左右方向X上被定位。
各个第二电极32配置于壳体30的内部空间30A，并架设于上支承部35的主体部35A与下支承部36的主体部36A之间。各个第二电极32既可以沿上下方向Z垂直地延伸，也可以以随着趋向下方Z2而向前方Y1或后方Y2偏移的方式相对于上下方向Z倾斜。也可以是，在主体部35A以沿左右方向X排列的 方式设有向上方Z1突出的板状的突出部35AA。也可以是，在主体部36A以沿左右方向X排列的方式设有向下方Z2突出的板状的突出部36AA。
在本实施方式中，第一电极31的极性为接地侧的负极，第二电极32的极性为正极。当从设于洗干一体机1的电源(未图示)向带电部24施加了电压时，会向第一电极31与第二电极32之间施加几kV～几十kV的高电压，由此第二电极32放电。如此，第二电极32周围的空气成为等离子体状态，该空气中的分子阳离子化并向第一电极31移动。由此，第一电极31与第二电极32之间会流过几十μA的电流。
在壳体30的内部空间30B中，通过第二电极32的放电，流过第一电极31与第二电极32之间的空气中所含的水分由于与阳离子、电子碰撞而使正极带电。正极被带电了的水分被吸向负极的第一电极31，被第一电极31收集。由此，第一电极31与第二电极32之间的空气被除湿。
被第一电极31收集的水分在第一电极31的表面成为水滴，因自重而沿着第一电极31的下端缘31A的倾斜流动(参照图2的箭头Q1)，落到斜坡30N的上表面上。落到斜坡30N上的水分沿着斜坡30N的上表面的倾斜流下而流入引导箱30H的内部空间(参照图2的箭头Q2)，沿着引导箱30H的底面30I的倾斜流下而从排水口30J流入连结部30K内(参照图6的箭头Q3)。
像这样，在本实施方式中，第一电极31具有与带电的水分相反的极性而收集该水分。需要说明的是，也可以采用第一电极31的极性为正极且第二电极的极性为负极的相反的结构，而在该结构中，也是第二电极32放电而第一电极31集水。
需要说明的是，在本实施方式中，与空气在壳体30内以上升的方式流动这一点相应地，壳体30的入口30C和出口30D以沿上下方向Z排列的方式配置，但也可以是，空气在壳体30内沿左右方向X等横向流动，在该情况下，也可以以入口30C和出口30D横向排列的方式变更壳体30的姿势。无论如何，第一电极31和第二电极32以不会阻碍从入口30C流向出口30D的空气的方式沿该空气的流动配置。
图7是收集部25的俯视图。收集部25在循环路20中的空气的流动方向上 配置于带电部24的下游侧，在本实施方式中，在带电部24的上方Z1相邻配置(参照图1)。收集部25包括：树脂制且中空的壳体40；多个第三电极43，配置于壳体40内；以及第四电极44，配置于相邻的第三电极43之间。
壳体40的一个例子是由沿上下方向Z延伸的四个纵壁40A构成的长方体。由这些纵壁40A包围的空间是壳体40的内部空间40B。在壳体40形成有被四个纵壁40A的下端包边的矩形的入口40C和被四个纵壁40A的上端包边的矩形的出口40D(也参照图8)。内部空间40B从入口40C向下方Z2敞开，从出口40D向上方Z1敞开。
壳体40构成循环路20的后部分20B中的沿上下方向Z延伸的部分的一部分(参照图1)。壳体40的内部空间40B、入口40C和出口40D构成在循环路20的内部空间中沿上下方向Z延伸的区域的一部分。通过使壳体30与壳体40连结，壳体40的入口40C从上方Z1与带电部24的壳体30的出口30D(参照图3)连通。壳体30和壳体40也可以一体地形成。
图8是图7的B－B向视剖视图。在本实施方式中，流过循环路20并在带电部24的壳体30内经过的空气在壳体40内从入口40C向出口40D上升(参照粗虚线箭头)。在四个纵壁40A中，一对纵壁40AA以与剩余的一对纵壁40AB正交的方式配置。一对纵壁40AA中的一方的下端部包括：贯通孔40E；斜坡40F，从贯通孔40E的下端向内部空间40B突出；以及引导箱40G，从壳体40之外覆盖贯通孔40E。
贯通孔40E、斜坡40F以及引导箱40G在一对纵壁40AB的对置方向R上为长边。对置方向R可以是左右方向X，也可以是前后方向Y。贯通孔40E和斜坡40F以在内部空间40B中遍及对置方向R的整个区域的方式配置。斜坡40F以从贯通孔40E向斜上侧倾斜的方式配置，斜坡40F的上表面40H也倾斜。在上表面40H中的最远离贯通孔40E的上端部设有向上方Z1突出的突出部40I。
引导箱40G的内部空间40J处于与贯通孔40E连通的状态。图9是图7的C－C向视剖视图。引导箱40G中的从下方Z2划分出内部空间40J的底面40K经由贯通孔40E与斜坡40F的上表面40H的下端连接。底面40K例如是随着趋向对置方向R中的一个方向而逐渐下降的倾斜面，在其下端形成有排水口40L。在引导箱40G的下表面设有以包围排水口40L的状态向下方Z2突出的圆筒状 的连结部40M。
第三电极43是在对置方向R上薄的板状的对置电极，例如由不锈钢或铝形成，由此具有导电性。在本实施方式中，七片第三电极43在壳体40的内部空间40B中以在对置方向R上等间隔地排列的方式配置(参照图7)。各第三电极43通过使从其上端部突出的突出部43A卡合于壳体40的出口40D的台阶部40N而被定位在内部空间40B。需要说明的是，也可以是，沿对置方向R延伸的连结轴45将各第三电极43的突出部43A串成一串，从而使所有的第三电极43一体化(参照图8)。
各第三电极43中的壳体40的入口40C侧的下端缘43B以朝着纵壁40AA的贯通孔40E逐渐下降的方式直线状倾斜。各第三电极43的下端缘43B中的贯通孔40E侧的下端部配置于斜坡40F的正上方，在上下方向Z上配置于与贯通孔40E相同的位置。
图10是从图8中抽出第四电极44的图。各第四电极44是具有在一对纵壁40AA的对置方向S(参照图8)上长尺寸的主体44A和覆盖主体44A的大部分的绝缘体44B的绝缘电极。对置方向S是与上述的对置方向R正交的方向。主体44A例如由铜形成，由此具有导电性。主体44A具有与第三电极43相反的极性。绝缘体44B呈在一对纵壁40AA的对置方向R上薄且在对置方向S上长的长方形的板状。
第四电极44逐一配置于相邻的第三电极43之间，以不与第三电极43接触的状态架设于一对纵壁40AA之间(参照图7和图8)。从对置方向R观察，各第四电极44的大部分以与各第三电极43重叠的方式配置(参照图8)。主体44A中的从绝缘体44B露出的根部44AA和绝缘体44B中的根部44AA侧的部分配置于壳体40之外。
在本实施方式中，第三电极43的极性为接地侧的负极，第四电极44的极性为正极。当从设于洗干一体机1的电源(未图示)向收集部25施加了电压时，会向第三电极43与第四电极44之间施加几kV～几十kV的高电压。其中，第四电极44的表面由绝缘体44B构成，因此第三电极43与第四电极44之间不流过电流。因此，能够防止因第三电极43与第四电极44之间的漏电(leak)等而导致跳火(spark)、电压变动。
另一方面，第三电极43与第四电极44之间会产生电场，因此在通过带电部24使正极带电了的状态下流入到收集部25的壳体40内的水分在本实施方式中会被负极的第三电极43收集。由此，收集部25能有效地收集带电的水分。因此，由带电部24进行了除湿的空气会被进一步除湿。
被第三电极43收集的水分在第三电极43的表面成为水滴，因自重而沿着第三电极43的下端缘43B的倾斜流动(参照图8的箭头T1)，落到斜坡40F的上表面40H上。落到上表面40H上的水分沿着上表面40H的倾斜流下而流入引导箱40G的内部空间40J(参照图8的箭头T2)，沿着引导箱40G的底面40K的倾斜流下而从排水口40L流入连结部40M内(参照图9的箭头T3)。
需要说明的是，也可以采用第三电极43的极性为正极且第四电极44的极性为负极的相反结构。此外，在本实施方式中，与空气在壳体40内以上升的方式流动这一点相应地，壳体40的入口40C和出口40D以沿上下方向Z排列的方式配置，但也可以是，空气在壳体40内沿横向流动，在该情况下，也可以以入口40C和出口40D横向排列的方式变更壳体40的姿势。无论如何，第三电极43和第四电极44以不会阻碍从入口40C流向出口40D的空气的方式沿该空气的流动配置。此外，在通过带电部24能够确保充分的除湿性能的情况下，也可以省略收集部25。
参照图1，除湿设备23还包括从带电部24和收集部25向下方Z2延伸并与排水路7连接的排出路46。排出路46的一端部46A分支，分别与带电部24的连结部30K和收集部25的连结部40M连接(参照图6和图9)。
在图1中，排出路46中的与一端部46A相反的另一端部46B与排水路7直接连接。在带电部24中流入连结部30K内的水分、在收集部25中流入连结部40M内的水分流过排出路46，然后从排水路7向机外排出。另一端部46B也可以与水筒3的背面壁3B连接，在该情况下，流入连结部40M内的水分在流过排出路46而流入到水筒3内后，从排水路7向机外排出。
洗干一体机1包括：湿度检测部50，检测在容纳筒5与循环路20之间循环的空气的湿度；以及温度检测部51，检测该空气的温度。
作为湿度检测部50，能采用公知的湿度传感器。湿度检测部50包括：第一 湿度检测部50A，在循环路20内配置于流出口20D的附近；以及第二湿度检测部50B，在循环路20内配置于送风部21与收集部25之间。
作为温度检测部51，能采用热敏电阻等公知的温度传感器。温度检测部51包括：第一温度检测部51A，在循环路20内配置于流出口20D的附近；以及第二温度检测部51B，在循环路20内配置于送风部21与收集部25之间。需要说明的是，配置于相近的位置的湿度检测部50和温度检测部51也可以一体化为一个湿度温度检测部。
洗干一体机1还包括控制部55。控制部55例如设为微机，包括：CPU(中央处理器)；ROM(只读存储器)、RAM(随机存取存储器)等存储器；以及计时用的计时器，控制部55内置于箱体2内。马达8、水位检测部14、供水阀15、排水阀17、送风部21、加热部22、带电部24、收集部25、湿度检测部50以及温度检测部51分别与控制部55电连接(参照图11)。水位检测部14、湿度检测部50以及温度检测部51各自的检测值被实时地输入至控制部55。在洗干一体机1中，容纳筒5、循环路20以及除湿设备23的集合构成除湿装置60。除湿装置60还可以包括控制部55。
控制部55通过对马达8、供水阀15、排水阀17、送风部21、加热部22、带电部24以及收集部25各自的动作进行控制来执行洗涤烘干运转。洗涤烘干运转包括：初始阶段的清洗过程、在清洗过程后执行一次或多次的漂洗过程、至少在最后的漂洗过程后执行的脱水过程以及最后阶段的烘干过程。这些过程可以是各自独立的运转，在该情况下，例如，清洗过程是清洗运转，烘干过程是烘干运转。
在清洗过程中，控制部55首先使马达8工作而使旋转筒4正转或反转，基于此时的马达8的电流值，判定旋转筒4内处于烘干状态的洗涤物L的质量。控制部55基于判定的洗涤物L的质量来决定需要的洗涤剂量和清洗过程中的水筒3内的目标水位。控制部55将决定的洗涤剂量的信息显示在设于箱体2的前表面2A等的显示操作部(未图示)。
然后，控制部55通过在关闭了排水阀17的状态下打开供水阀15来执行供水处理。由此，来自供水路6的自来水从供水口6A流入而蓄于水筒3内，因此水筒3内的水位上升。当由水位检测部14检测到水筒3内的水位上升至目标水 位时，控制部55通过关闭供水阀15来结束供水处理。在供水处理的前后，洗涤剂由用户手动投入或自动投入至旋转筒4内。由此，通过洗涤剂溶解于自来水而生成的洗涤剂水蓄于旋转筒4内。
作为供水处理后的清洗处理，控制部55通过马达8使旋转筒4旋转。由此，旋转筒4内的洗涤物L被捶洗。在捶洗中，反复进行洗涤物L被举起一定程度后自然落下至水面的所谓翻滚。通过由翻滚产生的冲击、蓄于旋转筒4的洗涤水中所含的洗涤剂成分，从洗涤物L去除污垢。当从翻滚开始经过了规定时间后控制部55打开排水阀17进行排水时，清洗过程结束。
在漂洗过程中，控制部55在关闭了排水阀17的状态下至少将供水阀15打开规定时间，向水筒3蓄留自来水，然后通过马达8使旋转筒4旋转。如此，反复进行上述的翻滚，因此洗涤物L被旋转筒4内的自来水漂洗。当从翻滚开始经过了规定时间后控制部55进行排水时，漂洗过程结束。
在脱水过程中，控制部55在打开排水阀17的状态下使旋转筒4脱水旋转。通过由旋转筒4的脱水旋转而产生的离心力，旋转筒4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7向机外排出。脱水过程不仅可以在漂洗过程后实施，也可以在清洗过程后实施。在最后的脱水过程之后，控制部55通过使旋转筒4快速地反复正转和反转，将旋转筒4内的洗涤物L从旋转筒4的圆周壁4A上剥离或松解开。由此，能防止洗涤物L在之后的烘干过程中产生褶皱。
控制部55通过至少控制送风部21、加热部22以及除湿设备23来执行烘干过程即烘干运转。在烘干运转中，通过送风部21和加热部22工作，热风产生并在容纳筒5与循环路20之间循环，被散布至旋转筒4内的洗涤物L。由此，通过洗涤物L内的水分与热风的热交换，该水分蒸发而成为水蒸气，因此会促进洗涤物L的烘干。
从容纳筒5内的洗涤物L产生的水蒸气随着循环的空气从流出口20D向循环路20流出。在烘干运转中，通过控制部55的控制对除湿设备23的带电部24和收集部25施加电压。由此，如上所述，承载从洗涤物L蒸发的水分并流过循环路20内的空气在经过带电部24的壳体30的内部空间30B和收集部25的壳体40的内部空间40B时被除湿。被除湿后的加热部22加热而成为热风，从流 入口20E流入容纳筒5内，再次用于洗涤物L的烘干。
参照图3，如上所述，在作为循环路20的一部分的带电部24的壳体30设有使循环路20的内部空间与外部空气连通的开口30E。由此，外部空气经过开口30E出入于循环路20的内部(参照图3的单点划线和双点划线的箭头)，从而循环路20的内外的温度差变小，因此能防止循环路20内的结露。因此，能抑制由结露引起的除湿装置60的除湿性能的降低。
此外，支承第二电极32的支承部34的一部分、即延伸设置部35B的外侧部分35BB和延伸设置部36B的外侧部分36BB从开口30E露出于循环路20外。由此，循环路20内的第二电极32的温度与循环路20外的温度之差变小，因此能防止第二电极32的结露。因此，能防止由于由结露产生的水滴而使第一电极31与第二电极32之间的间隙V变小，并将该间隙V维持为规定以上的大小，因此能使第二电极32的放电稳定。因此，能够进一步抑制由结露引起的除湿装置60的除湿性能的降低。需要说明的是，对于具有收集水分的功能的第一电极31，不需要特别的结露措施。
此外，在支承部34中配置于开口30E内的部分即延伸设置部35B的倾斜部分35BC和延伸设置部36B的倾斜部分36BC分别与循环路20处的开口30E的边缘30L、30M、30P以及30Q中的任一个之间设有间隙(也参照图4)。由此，在支承部34中配置于开口30E内的倾斜部分35BC和倾斜部分36BC暴露于流过周围的间隙的外部空气中，由此支承部34和第二电极32与外部空气的温度差变小，因此能防止支承部34和第二电极32的结露。此外，通过该间隙，支承部34与循环路20被分离并绝缘，因此能防止附着于循环路20的水分移动至支承部34，也能防止第二电极32侧的支承部34与第一电极31侧的循环路20之间的短路。
而且，在倾斜部分35BC和倾斜部分36BC各自的上表面部，即使附着有水滴，也能使该水滴沿该上表面部的倾斜流落到壳体30内，而不会停留在该上表面部上或向壳体30外逸出。用于防止水滴的滞留，倾斜部分35BC和倾斜部分36BC各自的表面部、特别是至少上表面部也可以被具有吸湿功能或防水功能的涂层覆盖。
此外，开口30E包括：导入口30EA，将外部空气导入至循环路20内；以 及排出口30EB，将循环路20内的空气排出至循环路20外。由此，外部空气从导入口30EA被导入至循环路20内(参照图3的单点划线的箭头)，循环路20内的空气从排出口30EB被排出至循环路20外(参照图3的双点划线的箭头)，由此循环路20的内外的温度差变小，因此能防止循环路20内的结露。因此，能抑制由结露引起的除湿装置60的除湿性能的降低。
在包括如上所述的除湿装置60并使空气在容纳筒5与循环路20之间循环的洗干一体机1中，如上所述，能抑制由结露引起的除湿装置60的除湿性能的降低。由此，在通过加热部22对由除湿装置60进行了除湿后的空气进行加热后返回至容纳筒5而再次用于洗涤物L的烘干时，能利用该空气使容纳筒5内的洗涤物L高效地烘干。
而且，控制部55在烘干运转的后期的最后，使加热部22停止，执行降温处理。在降温处理中，控制部55在使加热部22停止的状态下使送风部21持续工作。由此，通过冷风循环来降温容纳筒5内的洗涤物L、门10。然后，用户可以打开门10，从容纳筒5内取出洗涤物L。
本发明并不限定于以上说明的实施方式，可在技术方案所记载的范围内进行各种变更。
图12是变形例的带电部24和收集部25的剖视图。在图12中，对与此前说明的部分相同的部分标注相同的附图标记，省略关于该部分的说明。此外，在图12中，省略了收集部25内的第三电极43和第四电极44的图示。
在上述的实施方式中，在带电部24中的各个第二电极32中，上端部和下端部双方由支承部34支承(参照图3)。另一方面，如图12所示的变形例那样，在各个第二电极32中，也可以仅上端部由支承部34即上支承部35支承。与此相应地，省略带电部24的壳体30的下端部的开口30E和上述的下支承部36(参照图3)，在壳体40的纵壁40A设有开口40P。
在该情况下，开口40P作为上述的导入口30EA发挥功能，壳体30的上端部的开口30E作为排出口30EB发挥功能。因此，外部空气从开口40P被导入到壳体40内即循环路20内(参照图12的单点划线的箭头)，壳体30内即循环路20内的空气从排出口30EB被排出至循环路20外(参照图12的双点划线 的箭头)。由此，在变形例中循环路20的内外的温度差也变小，因此能防止循环路20内的结露。
此外，参照图1，烘干单元9也可以还包括从循环路20分支并与洗干一体机1的机外连通的排气路20F。在排气路20F中与机外连通的部分是形成于箱体2的排气口20G。
循环路20也可以与洗干一体机1的机外连通。在该情况下，在循环路20中与机外连通的部分是形成于箱体2的吸气口20H，在流入口20E与吸气口20H之间的区域配置有送风部21和加热部22。循环路20具有从与排气路20F连接的部分延伸至流入口20E与吸气口20H之间的区域为止的连接路20I。
在排气路20F设有对排气口20G进行开闭的排气阀61，在循环路20设有对吸气口20H进行开闭的吸气阀62。排气阀61和吸气阀62是调整阀，各自的开闭由控制部55控制。特别是，控制部55能调整排气阀61和吸气阀62各自的开度。
排气阀61和吸气阀62分别在开度为零时处于关闭状态。当控制部55使开度增大而打开了排气阀61时，排气口20G被打开，因此排气路20F内的空气向机外排出。当控制部55使开度增大从而打开了吸气阀62时，吸气口20H被打开，因此外部空气能流入至循环路20内。也可以在吸气口20H设置捕获外部空气中所含的异物的过滤器(未图示)。
在连接路20I设有切换部63。切换部63由可开闭的调整阀等构成。控制部55通过调整切换部63的开度来对切换部63进行开闭。切换部63在开度为零时处于关闭的状态。当控制部55使开度增大从而打开了切换部63时，循环路20开通，因此，当在该状态下送风部21工作时，循环路20内的空气会如上所述进行循环。另一方面，当切换部63关闭时，循环路20在连接路20I中被切断，因此循环路20内的空气会流向排气路20F而向机外排出。像这样，切换部63通过控制部55的控制来使循环路20内的空气流向排气路20F或流向连接路20I。
需要说明的是，在循环路20中，也可以省略连接路20I。在该情况下，当送风部21工作时，外部空气从吸气口20H流入至循环路20，通过加热部22加热而成为热风，热风从流入口20E散布至容纳筒5内的洗涤物L后，从流出口 20D向循环路20流出，经由排气路20F从排气口20G向机外排出，因此烘干运转中的空气不循环而始终单向地流动。
此外，除湿装置60除了可应用于洗干一体机1以外，还可应用于上述的餐具洗干一体机、电热水壶、电饭煲、冰箱、冷冻柜。
