Description

洗衣干衣机 技术领域
本发明涉及洗衣干衣机。
背景技术
以往，已知在通过配置于洗涤脱水桶的底部的波轮使洗涤脱水桶内产生水流来进行衣物的洗涤的所谓波轮式洗衣机(全自动洗衣机)中搭载了衣物的烘干功能的洗衣干衣机。例如，专利文献1中记载了这种洗衣干衣机的一个例子。
在专利文献1的洗衣干衣机中，设置有与外桶(水桶)之间循环暖风的循环管道，在循环管道内配置有鼓风机和加热器。在循环管道的鼓风机的上游，设置有通过开口部来摄入外部空气的外部空气导入管道。开口部通过开闭构件进行开闭。而且，为了使暖风从外桶排出至机体外部，设置有排风管道。
在烘干过程中，设置有内部空气循环期间和外部空气导入期间。在内部空气循环期间，开口部由开闭构件关闭，外部空气不导入循环管道。因此，几乎不进行从外桶内通过排风管道进行的排风，而由于暖风在烘干管道与外桶之间循环，洗涤脱水桶(脱水桶)内的温度快速上升。当洗涤脱水桶内的温度持续上升，水分从洗涤物蒸发而使暖风中含有大量水分时，切换至外部空气导入期间。开口部由开闭构件打开，外部空气被导入循环管道内。外部空气被加热器加热变成暖风，与循环的暖风一起供给至外桶内。由此，外桶内的含有大量水分的暖风的一部分通过排风管道排出至机体外部，因此，从洗涤物蒸发的水分有效地从外桶内排出至机体外部。
在上述的洗衣干衣机中，从洗涤脱水桶内的洗涤物中出来的棉绒等异物能与暖风一起被摄入循环管道内。此外，尘埃等异物能与外部空气一起被摄入循环管道内。因此，需要通过过滤器来捕集这些异物，以使这些异物不附着于加热器。
但是，在分别独立设置捕集外部空气中所含的异物的过滤器和捕集暖风中 所含的异物的过滤器的情况下，机壳内需要分别配置过滤器的空间，可能会导致机壳的尺寸变大。

本发明的主要方案的洗衣干衣机具备：外桶，弹性支承于机壳内；洗涤脱水桶，可旋转地配置于所述外桶内；循环风路，配置有加热器和鼓风扇，使通过所述加热器和所述鼓风扇的工作而产生的暖风在其与所述外桶之间循环；外部空气摄入口，用于将外部空气摄入所述循环风路；排风口，用于将来自所述外桶的暖风排出所述外桶和所述循环风路之外；进风过滤器室，在所述循环风路中，设置于比所述加热器和所述鼓风扇更靠近暖风的流向的上游侧；以及进风过滤器，收容于所述进风过滤器室内。此处，在所述进风过滤器室内，所述进风过滤器以一端侧高而另一端侧低的方式倾斜配置。而且，在所述进风过滤器室，在由所述进风过滤器分出的所述进风过滤器室内的两个空间中的一方空间侧，形成有供从所述外部空气摄入口摄入的外部空气导入的外部空气导入口和供来自所述外桶的暖风导入的内部空气导入口，在另一方空间侧，形成有供通过所述进风过滤器的暖风和外部空气导出的导出口。
根据上述的结构，能用一个进风过滤器来捕集外部空气中所含的异物和循环的暖风中所含的异物。因此，与通过分开设置的过滤器来捕集这些异物的情况相比，能缩小过滤器所需的机壳内的空间，机壳的尺寸不容易变大。而且，由于进风过滤器以一端侧高而另一端侧低的方式倾斜配置于进风过滤器室，因 此无需增高进风过滤器室，就能确保异物的捕集面积较大。因此，即使由于通过一个进风过滤器来捕集外部空气和暖风中所含的异物而使得进风过滤器中的异物的捕集量变多，进风过滤器也不容易堵塞，因而能抑制进风过滤器的清扫频率增加。而且，能抑制机壳的高度增高。
在本方案的洗衣干衣机中，可以采用如下结构，所述进风过滤器室具有：第一面，形成有所述外部空气导入口；第二面，与所述第一面交叉，并形成有所述内部空气导入口；以及第三面，与所述第一面或所述第二面对置，并形成有所述导出口。
在采用了上述结构的情况下，可以采用如下结构：还具备保持框，保持所述进风过滤器，并与进风过滤器一起收容于所述进风过滤器室。在该情况下，所述保持框包括：第一壁面，沿着所述第一面；以及第二壁面，沿着所述第二面，在所述第一壁面形成有外部空气流通口，供外部空气通过，在所述第二壁面形成有内部空气流通口，供暖风通过。
根据上述的结构，由于进风过滤器通过保持框得到加强，因此在将进风过滤器装卸于过滤器室时进风过滤器不容易产生变形、破损等。而且，通过形成于保持框的外部空气流通口和内部空气流通口，能使外部空气和暖风顺利地流向进风过滤器。
在采用了上述结构的情况下，可以采用如下结构：通过设置于沿着所述第一面和所述第二面的方向的所述进风过滤器的端部与所述保持框的端部之间的铰链部，可分离地连结所述进风过滤器和所述保持框。
当采用这样的结构时，无需将进风过滤器相对于保持框大幅打开而仅转动90度，就能容易地清扫进风过滤器。
如上所述，在第一面形成有外部空气导入口，在第二面形成有内部空气导入口，并在第三面形成有导出口的情况下，进而，可以采用如下结构：在与所述第一面和所述第二面交叉的第四面，形成有插入口，用于将所述进风过滤器插入所述进风过滤器室内。
根据上述的结构，通过从在未形成外部空气导入口、内部空气导入口以及导出口的第四面形成的插入口插入进风过滤器，从而能使进风过滤器容易地配置于进风过滤器室内。
在本方案的洗衣干衣机中，可以采用如下结构：还具备：排风路，供从所 述排风口排出的暖风流过；排风过滤器室，设置于所述排风路；以及排风过滤器，收容于所述排风过滤器室。在该情况下，所述排风过滤器室以在所述进风过滤器的插入方向上与所述进风过滤器室相连的方式形成，并与所述进风过滤器室相连。所述排风过滤器以在所述进风过滤器的插入方向上相连的方式与所述进风过滤器一体地形成，所述进风过滤器在收容于所述进风过滤器室的情况下，收容于所述排风过滤器室。在所述进风过滤器与所述排风过滤器之间，设置有分隔部，将所述进风过滤器室和所述排风过滤器室之间分隔。
当采用这样的结构时，能通过一个过滤器来实现进风过滤器和排风过滤器，用户的便利性高。而且，由于当进风过滤器和排风过滤器分别收容于进风过滤器室和排风过滤器室时，进风过滤器室与排风过滤器室的连通被分隔部隔断，因此在烘干运转时不容易产生进风过滤器室与排风过滤器室之间的漏风。
需要说明的是，在排风过滤器与进风过滤器一体地设置的情况下，进而，还可以采用使所述进风过滤器的捕集面积大于所述排风过滤器的捕集面积的结构。
这样，即使由于通过排风过滤器的风量比通过进风过滤器的风量小而使得排风过滤器处的异物的捕集量比进风过滤器处的异物的捕集量少，在进风过滤器与排风过滤器之间，异物的蓄积情况也不容易相差太多。因此，不容易产生进风过滤器严重堵塞而排风过滤器却几乎不堵塞的情况，通过一次清扫，就能对进风过滤器和排风过滤器进行有效的异物去除。
如上所述，在排风过滤器与进风过滤器一体设置的情况下，进而，所述排风过滤器能以与所述进风过滤器朝向相同方向的方式，倾斜配置于所述排风过滤器室。
根据上述的结构，能将排风过滤器设定为与进风过滤器相同的形状，容易将排风过滤器与进风过滤器一体地形成。
需要说明的是，上述方案中的“相同方向”表述包括“大致相同方向”。

在外桶20内，配置有上表面打开的大致圆筒状的洗涤脱水桶24。在洗涤脱水桶24的内周面，遍及整周形成有许多脱水孔24a。在洗涤脱水桶24的上部，设置有平衡环25。在外桶20的底部，配置有波轮26。在波轮26的表面，呈放射状设置有多个叶片26a。
在外桶20的外底部，配置有产生驱动洗涤脱水桶24和波轮26的转矩的驱动单元30。驱动单元30包括驱动电机31和传递机构部32。传递机构部32具有离合器机构，通过该离合器机构的切换操作，在洗涤过程和漂洗过程中，将驱动电机31的转矩只传递给波轮26，从而只使波轮26旋转，在脱水过程中，将驱动电机31的转矩传递给波轮26和洗涤脱水桶24，从而使波轮26和洗涤脱水桶24一体旋转。
在外桶20的外底部，形成有排水口部20c。在排水口部20c，设置有排水阀40。排水阀40连接于排水软管41。当排水阀40被打开时，蓄于洗涤脱水桶24和外桶20的水通过排水软管41向机体外部排出。

烘干装置50包括：暖风产生单元51、风路单元52、过滤器单元53、进风管道54、以及排风管道55。
参照图4的(a)至(c)，暖风产生单元51包括：壳体100、鼓风扇110、以及加热器120。壳体100通过将上表面开口的下壳体101和下表面开口的上壳体102结合而形成。在下壳体101，形成有吸入口103和排出口104。鼓风扇110包括：鼓风机111、以及用于使鼓风机111旋转的鼓风电机112。鼓风机111配置为在壳体100的内部与吸入口103对置，鼓风电机112配置于壳体100的外顶面。加热器120例如为半导体加热器，在壳体100的内部配置于吸入口103与排出口104之间。排出口104向下方突出，并连接于进风管道54的上端部。
参照图5的(a)至图8的(c)，风路单元52通过将上表面开口的下风路构件52a和下表面开口的上风路构件52b结合而形成，并包括：进风路210、过滤器室220、外部空气导入路230、以及暖风排出路240。
进风路210具有左右方向上长、上下方向上扁平的筒状。在进风路210，在右端部的上表面形成有与暖风产生单元51的吸入口103相连的风路出口211。
过滤器室220与进风路210邻接，具有前后方向上稍长的大致长方体的箱状。在过滤器室220的前表面，形成有用于供过滤器单元53插入的插入口221。过滤器室220包括：进风过滤器室250；排风过滤器室260，与进风过滤器室250的前方相连；以及分隔框270，从过滤器室220的内面向内侧突出并将进风过滤器室250与排风过滤器室260之间隔开。分隔框270的开口为供过滤器单元53的进风过滤器311和进风保持框321插入的插入口270a。与进风过滤器室250 相比，排风过滤器室260在前后方向上窄，在上下以及左右方向上宽。需要说明的是，分隔框270相当于本发明的第四面。
在进风过滤器室250，在左侧面250a形成有外部空气导入口251，在与左侧面250a正交的底面250b形成有内部空气导入口252，在与左侧面250a对置的右侧面250c形成有导出口253。外部空气导入口251与外部空气导入路230连通，导出口253与进风路210连通。内部空气导入口252向下方突出，并连接于排风管道55的上端部。需要说明的是，左侧面250a、底面250b以及右侧面250c分别相当于本发明的第一面、第二面以及第三面。
在排风过滤器室260，在左侧面260a形成有排风导入口261，在后表面260b的上部形成有排风导出口262。排风导出口262与暖风排出路240连通。
如图7的(a)至(c)所示，分隔框270包括框主体271和分隔用密封垫272。框主体271由树脂等比分隔用密封垫272硬的材料形成，具有与过滤器单元53的剖面形状对应的形状。分隔用密封垫272由橡胶等弹性材料形成，从外侧嵌入框主体271。分隔用密封垫272包括：前部273，覆盖框主体271的前表面；外周部274，从前部273延伸设置，覆盖框主体271的外周面；以及后部275，从外周部274延伸设置，覆盖框主体271的后表面。在前部273，形成有朝向前方呈喇叭状扩展的舌状片273a。
在过滤器室220的内面，在进风过滤器室250与排风过滤器室260的边界位置形成有嵌入槽222。嵌入槽222分为下风路构件52a侧和上风路构件52b侧而形成，在下风路构件52a与上风路构件52b结合时，分隔框270的外周部嵌入嵌入槽222。由此，分隔框270固定于过滤器室220内。此时，分隔用密封垫272的外周部夹持于框主体271的外周面与过滤器室220的内面之间。
外部空气导入路230邻接于过滤器室220，具有大致长方体的箱状。在外部空气导入路230，形成有供摄入外部空气的外部空气摄入口231。此外，在外部空气导入路230，设置有用于对外部空气摄入口231进行开闭的进风阀单元280。进风阀单元280包括：设置于外部空气摄入口231的挡风板281、电机282、以及连结挡风板281的旋转轴281a和电机282的连结轴283。电机282的旋转经由连结轴283传递至旋转轴281a，由此挡风板281被切换至关闭外部空气摄入口231的位置和打开外部空气摄入口231的位置。
暖风排出路240具有大致长方体的筒状，沿上下方向延伸。形成于暖风排出路240的上端部的排出口241与设置于上面板12的排风孔12a相连(参照图1)。
如图8的(a)至(c)所示，过滤器单元53包括：过滤器主体310；过滤器保持体320，保持过滤器主体310；前表面镶板330，用于堵塞过滤器室220的插入口221；以及两个铰链部340，可分离地连结过滤器主体310和过滤器保持体320。过滤器主体310包括：进风过滤器311；排风过滤器312，与进风过滤器311一体地设置于进风过滤器311的前方；以及分隔片313，设置于进风过滤器311与排风过滤器312之间，向上方突出。
排风过滤器312具有板状，包括：具有通风口317的排风过滤器框318、以及覆盖通风口317的过滤材料319。排风过滤器框318具有左右方向上长的方形，形成有通风口317的部位以从左侧向右侧下降的方式倾斜。通风口317通过十字形的格子318a分割为四个区域。过滤材料319包括网状的片材。
进风过滤器311的通风口314的面积即过滤材料316的捕集面积设为大于排风过滤器312的通风口317的面积即过滤材料319的捕集面积。
过滤器保持体320包括：进风保持框321；以及排风保持框322，与进风保持框321一体地形成于进风保持框321的前方。需要说明的是，进风保持框321相当于本发明的保持框。
进风保持框321形成为上表面开口的箱状。进风保持框321将倾斜的进风过滤器311保持在其上表面，因此，从正面观察的剖面形状构成大致直角三角形。在进风保持框321，在左侧壁面321a形成有包括多个开口的外部空气流通口323，底壁面321b形成有包括多个开口的内部空气流通口324。需要说明的是，左侧壁面321a和底壁面321b分别相当于本发明的第一壁面和第二壁面。
排风保持框322形成为上表面开口的箱状。排风保持框322将倾斜的排风过滤器312保持在其上表面，因此，从正面观察的剖面形状构成大致直角三角形。排风保持框322的前后的尺寸设为小于进风保持框321的前后的尺寸，上下以及左右的尺寸设为大于进风保持框321的上下以及左右的尺寸。在排风保持框322，在左侧壁面322a形成有包括多个开口的排风流通口325。兼用作进 风保持框321的前壁面321c的排风保持框322的后壁面322b与过滤器主体310的分隔片313结合，由此形成分隔板350。分隔板350相当于本发明的过滤器侧分隔部。
前表面镶板330与排风保持框322一体地形成于排风保持框322的前方，具有左右方向上长的方形。在前表面镶板330，在前表面形成有把手331，在后表面形成有用于安装插入口密封垫333的安装板332。插入口密封垫333形成为左右方向上长的方形的环状，安装于安装板332的外周缘。在插入口密封垫333，形成有朝向后方呈喇叭状扩展的舌状片333a。
铰链部340设置于进风过滤器311的后端部与进风保持框321的后端部即后壁面321d的上缘部之间。例如，在进风过滤器311侧形成有铰链部340的轴部341，在进风保持框321侧形成有铰链部340的轴承部342。如图8的(a)的虚线所示，过滤器主体310能以铰链部340为支点转动，相对于过滤器保持体320向后方打开。
过滤器室220的插入口221面向上面板12的外侧投入口14内，过滤器单元53在外侧投入口14内通过插入口221插拔于过滤器室220内。在过滤器单元53插入过滤器室220内时，进风过滤器311以及进风保持框321通过插入口270a插入进风过滤器室250内。进风保持框321的底壁面321b的比内部空气流通口324靠里侧向上方徐徐倾斜，由此，过滤器单元53具有顶端部在上下方向上呈锥形的形状(参照图9)。因此，在用户将过滤器单元53插入过滤器室220内时，进风过滤器311以及进风保持框321容易顺畅地通过插入口270a。此外，在分隔框270，在插入口270a的内周缘侧不存在分隔用密封垫272，因此进风过滤器311以及进风保持框321不会被分隔用密封垫272卡主，更容易顺畅地通过插入口270a。
如图9所示，在过滤器主体310以及过滤器保持体320收容于过滤器室220内的状态下，过滤器单元53的分隔板350与分隔框270的分隔用密封垫272在插入方向上抵接。由此，进风过滤器室250与排风过滤器室260之间通过分隔板350和分隔框270分隔，进风过滤器室250与排风过滤器室260的连通被隔断。而且，过滤器室220即排风过滤器室260由前表面镶板330关闭。在该状态下，插入口密封垫333与插入口221的周缘部在插入方向上抵接。
如图10所示，进风过滤器311在进风过滤器室250内以堵塞左侧面250a与右侧面250c之间的方式倾斜地配置于外部空气导入口251以及内部空气导入口252与导出口253之间。此外，进风保持框321的外部空气流通口323以及内部空气流通口324分别与外部空气导入口251以及内部空气导入口252对置。
如图11以及图12所示，排风过滤器312在排风过滤器室260内以堵塞左侧面260a与右侧面260c之间的方式倾斜地配置于排风导入口261与排风导出口262之间。此外，排风保持框322的排风流通口325与排风导入口261对置。
需要说明的是，风路单元52的进风路210和进风过滤器室250与暖风产生单元51的壳体100一起构成供暖风在其与外桶20之间循环的循环风路50a。
进风管道54是柔性管道，由橡胶等弹性材料形成，中间部分具有蛇腹部54a。同样，排风管道55也是柔性管道，由橡胶等弹性材料形成，中间部分具有蛇腹部55a。如图2所示，在外桶罩20b，在内侧投入口22a的后方形成有进风口22b以及排风口22c，进风管道54的下端部连接于进风口22b，排风管道55的下端部连接于排风口22c。
参照图3、图11以及图12，供水装置60包括：供水单元61、供水阀62、洗澡水泵63、以及供水管道64。供水单元61包括：供水箱410；洗涤剂容器420，能够出入于供水箱410内；以及供水管430，供从供水箱410排出的水通过。需要说明的是，供被提供给外桶20内的水流过的供水路60a由供水单元61和供水管道64构成。
供水箱410在上部具备水路411，在该水路411连接有供水阀62以及洗澡水泵63。此外，在供水箱410的底面形成有供水口412，在该供水口412连接有供水管430。在洗涤剂容器420收容有洗涤剂、柔顺剂。洗涤剂容器420在外侧投入口14内出入于供水箱410。
在供水管430，在右侧的内面形成有分支口431，朝向斜上方延伸的分支管440以从该分支口431分支的方式与供水管430一体形成。分支管440连接于排风过滤器室260的排风导入口261。在供水管430，在分支口431的上侧即分支口431的水流上游侧，形成有向内侧突出的檐状的突出部432。
在供水箱410的供水口412设置有止回阀单元450，该供水箱410的供水口 412是供水管430的分支口431的水流的上游侧，是洗涤剂容器420的水流的下游侧。
止回阀单元450包括：具有通水口451的环部452、以及从下方堵塞通水口451的底阀453。底阀453由橡胶等弹性材料形成，其一端的固定部453a固定于环部452。底阀453通过其弹力维持在堵塞通水口451的位置，当水流的力增加时，以固定部453a为支点倾斜下垂而打开。供水管430的分支口431设置于底阀453的固定部453a侧。
供水管道64是柔性管道，由橡胶等弹性材料形成，中间部分具有蛇腹部64a。供水管道64的上端部连接于供水管430。如图2所示，在外桶罩20b，在内侧投入口22a的后方形成有供水口22d，供水管道64的下端部连接于供水口22d。
需要说明的是，分支管440与风路单元52的排风过滤器室260以及暖风排出路240一起构成用于向全自动洗衣干衣机1之外排出暖风的排风路50b。
烘干装置50通过柔性进风管道54以及排风管道55连接于外桶20，供水装置60通过柔性供水管道64连接于外桶20。因此，在外桶20摇动时，进风管道54、排风管道55以及供水管道64吸收该摇动，因摇动产生的力难以施加于烘干装置50的暖风产生单元51、风路单元52和过滤器单元53、以及供水装置60的供水单元61、供水阀62和洗澡水泵63。
在全自动洗衣干衣机1中，进行各种运转模式的洗涤运转、洗涤烘干运转或烘干运转。洗涤运转是只进行洗涤的运转，按顺序执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。洗涤烘干运转是连续进行洗涤到烘干的运转，在最终脱水过程之后接着执行烘干过程。烘干运转是只进行烘干的运转，只执行烘干过程。
在洗涤过程以及漂洗过程中，在水蓄于洗涤脱水桶24内的状态下，波轮26向右方以及左方旋转。通过波轮26的旋转而在洗涤脱水桶24内产生水流。在洗涤过程中，洗涤物通过产生的水流和水中所含的洗涤剂而被洗涤。在漂洗过程，洗涤物通过产生的水流而被漂洗。
在洗涤过程、漂洗过程的供水过程中，供水阀62被打开。或者，在使用洗澡水的情况下，洗澡水泵63进行工作。由此，自来水或洗澡水被供给至供水箱 410的水路411。供给至水路411的水通过洗涤剂容器420与洗涤剂、柔顺剂混合，到达供水箱410的供水口412。
如图11所示，在供水口412内，底阀453因被水流推动而打开，从通水口451流出的水通过供水管430以及供水管道64从外桶罩20b的供水口22d供给至外桶20内。在此，如图11的箭头所示，流经供水管430内的水的一部分以流过底阀453的方式流动。流过底阀453的水在供水管430内难以朝向固定部453a侧的相反侧去往位于固定部453a侧的分支口431。由此，供水时，水难以渗入分支管440内。此外，流经固定部453a侧的水也会被突出部432反弹而远离分支口431，因此，水更加难以渗入分支管440内。而且，即使万一水渗入分支管440内，通过分支管440的倾斜，渗入的水也容易返回至供水管430内。
在中间脱水过程以及最终脱水过程中，洗涤脱水桶24以及波轮26一体地高速旋转。洗涤物通过洗涤脱水桶24产生的离心力的作用而被脱水。
在烘干过程中，首先进行内部空气循环烘干过程，接着进行外部空气导入烘干过程。在内部空气循环烘干过程中，外部空气摄入口231由挡风板281关闭(参照图10的实线的挡风板281)，在外部空气未被导入外部空气导入路230内的状态下，鼓风扇110以及加热器120进行工作。当鼓风扇110进行工作而使鼓风机111旋转时，如图4的(b)所示，空气从吸入口103被吸入并在壳体100内产生风。所产生的风被加热器120加热，变成暖风从排出口104排出，并通过进风管道54供给至外桶20内。
供给至外桶20内的暖风流经洗涤脱水桶24内。在洗涤脱水桶24内，波轮26按照固定的时间进行右旋转以及左旋转。洗涤脱水桶24内的洗涤物一边被波轮26搅拌，一边与流经洗涤脱水桶24内的暖风接触。如图10所示，流经洗涤脱水桶24内的暖风从外桶20内通过排风管道55排出，并通过进风过滤器室250以及进风路210再次从吸入口103吸入壳体100内。
在内部空气循环烘干过程中，由于外部空气未被摄入，因此几乎未通过供水管道64进行来自外桶20内的暖风的排风，暖风在包括壳体100、进风路210以及进风过滤器室250的循环风路50a与外桶20之间循环，由此，洗涤脱水桶24内的温度快速上升。
因波轮26的搅拌等而从洗涤物中出来的棉绒等异物混入从外桶20排出的暖风。暖风在进风过滤器室250内通过进风过滤器311，暖风中所含的异物被进风过滤器311捕集。
当洗涤脱水桶24内的温度继续上升，水分从洗涤物蒸发而使暖风中含有大量水分时，切换至外部空气导入烘干过程。向外部空气导入烘干过程的切换既可以基于烘干过程开始后的经过时间来进行，也可以基于由温度传感器检测到的外桶20内的温度、由湿度传感器检测到的外桶20内的湿度来进行。
在外部空气导入烘干过程中，挡风板281打开而使外部空气摄入口231被打开(参照图10的虚线的挡风板281)，在外部空气被导入外部空气导入路230内的状态下，鼓风扇110以及加热器120进行工作。如图10所示，导入外部空气导入路230的外部空气通过进风过滤器室250，与从排风管道55流过来的暖风混合，同时向进风路210流去，混合有外部空气的暖风被吸入壳体100内。此时，外部空气在进风过滤器室250内通过进风过滤器311，外部空气中所含的尘埃等异物被进风过滤器311捕集。
在外部空气导入烘干过程中，被摄入的外部空气使得供给至外桶20内的暖风的流量变多，因此要使外桶20内的含有大量水分的暖风的一部分通过供水路60a以及排风路50b排出至机壳10之外。即，如图12所示，外桶20内的暖风的一部分通过供水管道64排出至供水管430，依次流经分支管440、排风过滤器室260、暖风排出路240，从上面板12的排风孔12a排出。此时，流进供水管430内的暖风被朝向分支口431向上方倾斜的突出部432反弹而被导向分支口431侧，由此变得容易从分支口431进入分支管440内。此外，底阀453处于堵塞通水口451的状态，因此防止供水管430内的暖风向供水箱410内流入。而且，向暖风排出路240排出的暖风在排风过滤器室260内通过排风过滤器312，暖风中所含的棉绒等异物被排风过滤器312捕集。
如此，通过进行外部空气导入烘干过程，从洗涤物蒸发的水分有效地从外桶20内排出至机壳10之外，外桶20内变得容易除湿，因此可促进洗涤物的烘干。需要说明的是，来自外桶20的暖风的一部分流经循环风路50a并被加热器120重新加热，因此外桶20内的温度继续维持于较高的状态。外部空气导入烘干过程结束则烘干过程结束。
需要说明的是，进风过滤器室250与排风过滤器室260之间通过分隔板350和分隔框270隔断，因此防止流经排风路50b的暖风在过滤器室220内漏出至循环风路50a侧。
在重复进行洗涤烘干运转、烘干运转的期间，异物蓄积于进风过滤器311的过滤材料316、排风过滤器312的过滤材料319。当进风过滤器311、排风过滤器312由异物引起的堵塞变大时，为了清除这些过滤器311、312，从过滤器室220抽出过滤器单元53。然后，相对于过滤器保持体320打开过滤器主体310，清扫进风过滤器311的过滤材料316、排风过滤器312的过滤材料319的进风面侧，去除附着于进风面侧的异物。
(本实施方式的效果)
以上，根据本实施方式，进风过滤器311设置于外部空气导入口251以及内部空气导入口252与导出口253之间，因此，能通过一个进风过滤器311来捕集外部空气中所含的异物和循环的暖风中所含的异物。由此，与通过一一设置的过滤器来捕集这些异物的情况相比，能缩小过滤器所需的机壳10内的空间，机壳10的尺寸难以变大。并且，进风过滤器311在进风过滤器室250内以一端侧即左端侧高而另一端侧即右端侧低的方式配置，因此，不需要加高进风过滤器室250，就能确保增大过滤器材料316对异物的捕集面积。由此，即使通过一个进风过滤器311来捕集外部空气和暖风中所含的异物而增多了进风过滤器311对异物的捕集量，进风过滤器311也难以堵塞，因此，能抑制进风过滤器311的清扫频率增加。此外，能抑制机壳10的高度变大。
此外，根据本实施方式，采用如下结构：设置一体地形成有相互连通的进风过滤器室250和排风过滤器室260而成的过滤器室220，将一体地形成有进风过滤器311和排风过滤器312的过滤器单元53拆装于过滤器室220。因此，能将进风过滤器311和排风过滤器312处理成一个过滤器，用户的便利性高。并且，在过滤器单元53，在进风过滤器311与排风过滤器312之间形成有分隔板350，当过滤器单元53被插入过滤器室220内时，进风过滤器室250与排风过滤器室260的连通被分隔板350隔断，因此，在烘干运转时不易发生进风过滤器室250与排风过滤器室260之间的漏风。
而且，根据本实施方式，在过滤器室220内设置了向内侧伸出的分隔框270， 并使该分隔框270与过滤器单元53的分隔板350沿着进风过滤器室250和排风过滤器室260的排列方向抵接，因此，能可靠地屏蔽进风过滤器室250与排风过滤器室260之间。
而且，根据本实施方式，在分隔框270设置了分隔用密封垫272，并使分隔板350与分隔用密封垫272接触，因此，能更加可靠地屏蔽进风过滤器室250与排风过滤器室260之间。
而且，根据本实施方式，通过与过滤器室220分开设置的框主体271和分隔用密封垫272来构成了分隔框270，并在将框主体271安装于过滤器室220的内面的嵌入槽222时，使分隔用密封垫272的外周部274夹持于框主体271与嵌入槽222的底面即过滤器室220的内面之间，因此，能将分隔用密封垫272牢固地固定于过滤器室220，在使过滤器单元53的分隔板350与分隔用密封垫272抵接时，分隔用密封垫272不易错位或偏离。
而且，根据本实施方式，进风过滤器室250和排风过滤器室260沿过滤器单元53插入过滤器室220内的方向排列，因此，与进风过滤器室250和排风过滤器室260沿着与插入方向垂直的方向排列的情况不同，在设置有分隔用密封垫272的情况下，过滤器单元53就不会在被插入过滤器室220内时使分隔板350与分隔用密封垫272摩擦，不易发生难以将过滤器单元53插入过滤器室220内或分隔用密封垫272破损的情况。
而且，根据本实施方式，在过滤器单元53的前表面镶板330与过滤器室220的插入口221的周缘部之间设置有插入口密封垫333，因此，能将前表面镶板330与过滤器室220的插入口221之间可靠地密封。
而且，根据本实施方式，采用了进风过滤器311由进风保持框321保持且排风过滤器312由排风保持框322保持的结构，因此，过滤器单元53整体的强度被提高，在将过滤器单元53拆装于过滤器室220时，进风过滤器311、排风过滤器312难以产生变形、破损等。此外，在将过滤器单元53从过滤器室220卸下时，即使异物从进风过滤器311、排风过滤器312掉落，也能通过进风保持框321的底壁面321b、排风保持框322的底壁面来接受掉落的异物。而且，通过形成于进风保持框321的外部空气流通口323和内部空气流通口324，能使外部空气和暖风向进风过滤器311顺畅地流动，通过形成于排风保持框322的排 风流通口325，能使暖风向排风过滤器312顺畅地流动。
而且，根据本实施方式，可分离地连结有过滤器主体310和过滤器保持体320的铰链部340设置于进风过滤器311的后端部与进风保持框321的后壁面321d的上端部之间，因此，即使不将过滤器主体310相对于过滤器保持体320打开较大，仅使其转动90度左右，就能容易地清扫进风过滤器311、排风过滤器312。例如，如图14的(a)所示，在铰链部设置于进风过滤器的左端部与进风保持框的左侧壁面的上端部之间的情况下，即使将过滤器主体转动90度左右，过滤器主体也处于稍微朝下的状态，因此，为了容易进行清除，如虚线所示，需要进一步较大地转动过滤器主体。此外，如图14的(b)所示，在铰链部设置于进风过滤器的右端部与进风保持框的右侧壁面的上端部之间的情况下，与进风保持框的左侧壁面的上端部相比，铰链部的位置相当低，因此，只要使过滤器主体转动90度左右而使过滤器主体处于稍微朝上的状态，左侧壁面就容易变成障碍，为了容易进行清除，如虚线所示，还是需要较大地转动过滤器主体。
而且，根据本实施方式，从未形成有外部空气导入口251、内部空气导入口252以及导出口253的进风过滤器室250的前表面即分隔框270的插入口270a插入进风过滤器311，由此能容易使进风过滤器311配置于进风过滤器室250内。
而且，根据本实施方式，通过排风过滤器312的风量小于通过进风过滤器311的风量，因此，排风过滤器312对异物的捕集量小于进风过滤器311对异物的捕集量，但进风过滤器311的捕集面积大于排风过滤器312的捕集面积，因此，在进风过滤器311与排风过滤器312之间，异物的蓄积情况不易相差太多。因此，不易产生进风过滤器311严重堵塞而排风过滤器312却几乎不堵塞的情况，通过将过滤器单元53清扫一次，就能对进风过滤器311和排风过滤器312进行有效的异物去除。
而且，根据本实施方式，排风过滤器312以朝向与进风过滤器311相同的方向的方式在排风过滤器室260中倾斜配置，因此，能将排风过滤器312设为与进风过滤器311相同的形状，容易将排风过滤器312与进风过滤器311一体地形成。并且，能确保增大排风过滤器312的捕集面积，因此，在将过滤器单元53设为相同大小的情况下，能将进风过滤器311的捕集面积与排风过滤器312的捕集面积的比例保持规定，并且能在进风过滤器311和排风过滤器312的排 列方向上缩小排风过滤器312的尺寸并增大进风过滤器311的尺寸。由此，在将过滤器室220、过滤器单元53设为指定尺寸时，能确保进一步增大进风过滤器311的捕集面积。
(变更例)
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等的任何限制，此外，本发明的实施方式也可以进行上述以外的各种变更。
例如，可以采用如下结构：外部空气导入口251形成于进风过滤器室250的底面250b而不是左侧面250a，内部空气导入口252形成于进风过滤器室250的左侧面250a而不是底面250b。此外，可以采用如下结构：导出口253形成于进风过滤器室250的顶面。而且，外部空气导入口251和内部空气导入口252这两者可以形成于进风过滤器室250的同一面，例如左侧面250a、底面250b。
而且，如图15的(a)至(c)所示，进风过滤器室250A可以设为如下形状：从正面观察不是四边形，并在左右两侧具有与倾斜的进风过滤器31lA大致平行的倾斜面250d、250e。在该情况下，例如，如图15的(a)、(b)所示，可以在一方的倾斜面250d形成有外部空气导入口25lA和内部空气导入口252A，并在另一方的倾斜面250e形成有导出口253A。或者，如图15的(c)所示，可以使外部空气导入口25lA和内部空气导入口252A中的一方形成于一方的倾斜面250d，另一方形成于底面250f。即，进风过滤器室250的形状可以是任何形状，总之，只要在由进风过滤器311分隔出的进风过滤器室250内的两个空间中一方的空间侧形成有外部空气导入口251和内部空气导入口252，并在另一方的空间侧形成有导出口253即可。
此外，可以采用不在分隔框270设置分隔用密封垫272的结构，在该情况下，进风过滤器室250和排风过滤器室260可以沿与过滤器单元53向过滤器室220内的插入方向垂直的方向排列。
而且，分隔用密封垫272可以设置于分隔板350而不是分隔框270。在该情况下，分隔框270仅由框主体271构成，但此时框主体271可以与过滤器室220的内面一体形成。
而且，插入口密封垫333可以设置于过滤器室220侧而不是前表面镶板330 侧。
而且，排风过滤器312可以朝向与进风过滤器311稍微不同的方向。总之，只要排风过滤器312朝向与进风过滤器311大致相同的方向即可。
除此之外，本发明的实施方式可以在权利要求书所示的技术思想的范围内适当进行各种变更。
