Description

滚筒洗衣机和滚筒烘干机 技术领域
本发明涉及滚筒洗衣机和滚筒烘干机。
背景技术
专利文献1中记载有一种滚筒洗衣机，其被设为：在横轴型的滚筒的后表面配置具有突状部的旋转体，在清洗、漂洗时，使滚筒和旋转体分别以不同的转速旋转。
在专利文献1的滚筒洗衣机中，不仅能通过滚筒的旋转来将洗涤物提升又落下，还能通过旋转体的突状部来对洗涤物进行揉搓或者搅拌。即，在上述滚筒洗衣机中，对于滚筒内的洗涤物，不仅能赋予由滚筒的旋转产生的机械力，还能赋予由旋转体的旋转产生的机械力，因此能提高洗净力。
对洗涤物赋予的机械力越大，则与之相应地，洗涤物越容易产生布料损伤。因此，理想的是，不对受污轻微的洗涤物、容易产生布料损伤的洗涤物赋予较大的机械力。
因此，若能实现将受污严重等而期望赋予较高机械力的洗涤物和受污轻微等而不期望较高机械力的洗涤物分开容纳于滚筒内，对前者的洗涤物赋予由滚筒的旋转和旋转体的旋转产生的机械力并且对后者的洗涤物仅赋予由滚筒的旋转产生的机械力的滚筒洗衣机，则能良好地进行前者的洗涤物的去污，并且能减少后者的洗涤物的布料损伤，而且还能同时对双方的洗涤物进行洗涤，较为方便。
而且，在上述滚筒洗衣机是具有烘干功能的滚筒洗干一体机的情况下，理想的是，在烘干时有效地减少衣物等被烘干物的起皱。在滚筒洗干一体机以外的滚筒烘干机即仅具有烘干功能的滚筒烘干机中也同样，理想的是，在烘干时有效地减少被烘干物的起皱。

图3和图4是表示驱动部30的构成的剖视图。图3表示驱动部30的驱动形态被切换为双轴驱动形态的状态，图4表示驱动部30的驱动形态被切换为单轴驱动形态的状态。
驱动部30包括驱动马达110、第一旋转轴120、第二旋转轴130、行星齿轮机构140、轴承单元150以及离合机构部160。
驱动马达110是外转子型的DC无刷马达，产生用于对旋转体26和滚筒23进行驱动的转矩。驱动马达110包括转子111和定子112。在转子111的中央部形成有环状的被卡合凹部113。被卡合凹部113内的外侧的周面以遍及整周的方式具有凹凸部。
第一旋转轴120具有中央部向外侧鼓出的中空形状，内含第二旋转轴130和行星齿轮机构140。
行星齿轮机构140将第二旋转轴130的旋转即驱动马达110的转子111的旋转减速后传递给第一旋转轴120。行星齿轮机构140包括太阳齿轮141、包围太阳齿轮141的环状的内齿轮142、介于太阳齿轮141与内齿轮142之间的多个行星齿轮143以及旋转自如地保持这些行星齿轮143的行星架144。
太阳齿轮141固定于第二旋转轴130，内齿轮142固定于第一旋转轴120。各行星齿轮143包括相互咬合且向相反的方向旋转的第一齿轮和第二齿轮。行星架144包括向后方延伸的架轴144a。架轴144a与第一旋转轴120同轴，内部形成为中空以供第二旋转轴130插入。
第二旋转轴130的后端部从架轴144a向后方突出，固定于转子111的中央部。
轴承单元150通过设于其内部的两个轴承151、152来将第一旋转轴120支承为能旋转。在轴承单元150的后端部的内表面以遍及整周的方式形成有花键153。轴承单元150固定于外筒20的后表面，在该状态下，第一旋转轴120和第二旋转轴130探入外筒20的内部。滚筒23固定于第一旋转轴120，旋转体26固定于第二旋转轴130。
离合机构部160在双轴驱动形态和单轴驱动形态之间对驱动部30的驱动形态进行切换，其中，双轴驱动形态是以使旋转体26以比滚筒23的转速快的转 速旋转的方式使滚筒23和旋转体26分别旋转的驱动形态，单轴驱动形态是以使滚筒23和旋转体26以相同的转速旋转的方式使滚筒23和旋转体26一体旋转的驱动形态。
离合机构部160包括离合器体161、离合器弹簧162、离合器杆163、杆支承部164、中继棒165以及离合器驱动装置166。
离合器体161以能沿前后方向移动但无法沿周向转动的状态装接于架轴144a的后部。
在离合器体161的前端部的外周面形成有环状的花键161a。而且，在离合器体161的后端部形成有环状的卡合凸缘部161b。卡合凸缘部161b具有与转子111的被卡合凹部113的形状相同的形状，在其外周部以遍及整周的方式具有凹凸部。
离合器弹簧162的一端与轴承单元150的后端部相接，另一端与离合器体161相接。离合器弹簧162向后方即转子111侧按压离合器体161。
离合器杆163转动自如地支承于设于杆支承部164的支轴164a。离合器杆163的上端部以能向前方按压离合器体161的方式与离合器体161接触。中继棒165的上端连接于离合器杆163的下端部。
离合器驱动装置166包括转矩马达166a和通过转矩马达166a的转矩而绕水平轴旋转的圆盘状的凸轮166b。中继棒165的下端连接于凸轮166b。
在将驱动部30的驱动形态从单轴驱动形态切换向双轴驱动形态的情况下，如图3所示，中继棒165被离合器驱动装置166下拉。离合器杆163以支轴164a为中心向前方旋转，离合器体161被离合器杆163的上端部按压而向前方移动。由此，离合器体161的花键161a与轴承单元150的花键153卡合。离合器体161呈无法相对于轴承单元150沿周向转动的状态，行星齿轮机构140的架轴144a即行星架144呈被固定为无法旋转的状态。
当转子111旋转时，第二旋转轴130旋转从而旋转体26旋转。随着第二旋转轴130的旋转，在行星齿轮机构140中，太阳齿轮141旋转。行星架144被固定，因此行星齿轮143的第一齿轮和第二齿轮分别向与太阳齿轮141相反的方向和相同的方向旋转，内齿轮142向与太阳齿轮141相同的方向旋转。由此， 固定于内齿轮142的第一旋转轴120向与第二旋转轴130相同的方向以比第二旋转轴130的转速慢的转速旋转，从而滚筒23以比旋转体26的转速慢的转速向与旋转体26相同的方向旋转。换言之，旋转体26以比滚筒23的转速快的转速向与滚筒23相同的方向旋转。
另一方面，在将驱动部30的形态从双轴驱动形态切换向单轴驱动形态的情况下，如图4所示，中继棒165被离合器驱动装置166上推。离合器杆163以支轴164a为中心向后方旋转，离合器体161被离合器弹簧162按压而向后方移动，离合器体161的卡合凸缘部161b和转子111的被卡合凹部113各自的凹凸部彼此卡合。离合器体161无法相对于转子111沿周向转动，离合器体161呈能与转子111一起旋转的状态。
当转子111旋转时，第二旋转轴130和离合器体161以与转子111的转速相等的转速旋转。此时，在行星齿轮机构140中，太阳齿轮141和行星架144以与转子111的转速相等的转速旋转。由此，内齿轮142以与太阳齿轮141和行星架144的转速相等的转速旋转，固定于内齿轮142的第一旋转轴120以与转子111的转速相等的转速旋转。即，在驱动部30中，第二旋转轴130、行星齿轮机构140以及第一旋转轴120一体旋转。由此，滚筒23和旋转体26一体旋转。
接着，对分隔板27的构成进行详细说明。
图5的(a)和(b)分别是装配有第一固定件310的分隔板27的主视立体图和后视立体图。
分隔板27具有大致圆盘状，其外径与滚筒23的内径大致相等。分隔板27包括分隔主体210、门220、铰链230以及门锁机构240。分隔主体210和门220由金属材料、树脂材料形成。
分隔主体210形成为圆盘状。在分隔主体210的中央形成有圆形的出入口211。出入口211的直径比分隔板27的直径的一半大。此外，在分隔板27的外周缘部，以沿周向隔出大致120度的间隔的方式形成有具有与大型提升筋25a的截面大致相同的V字形状的两个大型缺口部212和具有与小型提升筋25b的截面大致相同的V字形状的一个小型缺口部213。而且，在分隔板27以呈圆环 状环绕出入口211的方式形成有多个通气口214。
三个第一固定件310装配于分隔主体210的前表面中的各大型缺口部212的内侧和小型缺口部213的内侧。各第一固定件310具有与大型提升筋25a或小型提升筋25b的顶端部的形状对应的U字状的嵌合部311。
门220形成为圆盘状，具有与出入口211的直径相等的直径，堵塞出入口211。门220具有由两个铰链223将半圆板状的第一门构件221和第二门构件222连结而得到的构成，能折叠成两折。门220在分隔板27的前表面侧通过铰链230与分隔主体210连结，以铰链230为轴，向前后方向开闭。在门220的后表面设有从中央部呈辐射状延伸的三个突起部224。
需要说明的是，突起部224的个数不限于三个，也可以是任意个。此外，突起部224也可以设于分隔主体210中的出入口211的周围。
在门220中的与铰链230相对的那一侧的部分设有门锁机构240。门锁机构240在出入口211被门220关闭的状态下以门220不会打开的方式进行锁定，并且基于解除操作来解除门220的锁定。
图6是分隔板27中的门锁机构240的周边部的侧视剖视图。
门锁机构240包括外壳241、闩锁体242、弹簧243以及解除杆244。外壳241包括前表面开口的第一容纳部241a和位于第一容纳部241a的后方的第二容纳部241b。在外壳241中，在第一容纳部241a设有转动轴241c，在第二容纳部241b的与分隔主体210对置的面形成有开口部241d。
闩锁体242以其顶端部242a能从外壳241经过开口部241d出入的方式容纳于外壳241的第二容纳部241b。弹簧243配置于第二容纳部241b内，向该闩锁体242的顶端部242a会从外壳241突出的方向对闩锁体242赋予弹力。
解除杆244能以转动轴241c为中心转动地配置于外壳241的第一容纳部241a。解除杆244包括长圆环状的手柄部244a和向第二容纳部241b侧突出而与闩锁体242卡合的按压部244b。
在分隔主体210，在其后表面通过装配闩锁孔构成构件250而形成有闩锁孔251。在门220被关闭的状态下，闩锁体242的顶端部242a从外壳241突出而嵌入闩锁孔251。由此，门220被固定在关闭的状态。
在要打开门220时，通过用户的手指捏住手柄部244a来进行使解除杆244向前方转动的解除操作。闩锁体242被解除杆244的按压部244b按压而向弹簧243侧移动，闩锁体242的顶端部242a从闩锁孔251脱离而缩入外壳241内。由此，门220的固定被解除。
图7是在分隔板27的前方剖切而得到的滚筒23的主视剖视图。
在分隔板27配置于滚筒23内的状态下，分隔板27的两个大型缺口部212和小型缺口部213分别嵌入两个大型提升筋25a和小型提升筋25b。分隔板27通过三个第一固定件310而固定于两个大型提升筋25a和小型提升筋25b。此时，三个第一固定件310的嵌合部311嵌合于两个大型提升筋25a和小型提升筋25b的顶端部。而且，分隔板27通过三个第二固定件320而固定于滚筒23的内周面。各第二固定件320具有L字状，螺纹紧固于分隔主体210和滚筒23的内周面。
滚筒洗衣机1中进行各种运转进程的洗涤运转、洗涤烘干运转以及烘干运转。洗涤运转中依次进行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。在洗涤烘干运转中，在最终脱水过程之后进行烘干过程。烘干运转中只进行烘干过程。需要说明的是，根据运转进程，有时会进行两次以上漂洗过程和中间脱水过程。
洗涤运转和洗涤烘干运转中均包括双重洗净模式和单一洗净模式。滚筒洗衣机1准备了进行双重洗净模式的运转的运转进程和进行单一洗净模式的运转的运转进程。
在双重洗净模式的运转中，在滚筒23的第二室28b内和第一室28a内分别容纳受污严重等而希望通过较高的机械力来强力洗净的洗涤物和受污不严重、容易产生布料损伤等而不希望通过较高的机械力来强力洗净的洗涤物。在清洗过程中，在第一室28a内进行利用滚筒23的旋转实现的洗涤物的洗净，在第二室28b内进行利用滚筒23的旋转和与滚筒23的转速不同的转速下的旋转体26的旋转实现的洗涤物的洗净。
在单一洗净模式的运转中，洗涤物不进行分类地容纳于第一室28a内和第二室28b内。在清洗过程中，在第一室28a内和第二室28b内进行利用滚筒23 的旋转实现的洗涤物的洗净。
在使洗涤物出入于滚筒23的第二室28b内时，用户打开分隔板27的门220，经过出入口211使洗涤物出入于第二室28b内。如图1的单点划线所示，打开的门220被折叠成两折。折叠的门220收纳于第一室28a内。由此，门220不易成为障碍，能顺利地进行洗涤物向第二室28b内的出入。
需要说明的是，理想的是，滚筒洗衣机1在运转结束时进行滚筒23的停止控制以便滚筒23以如下状态停止：小型提升筋25b位于最下点，门220能自上向下打开。若如此设置，则即使用户从手中释放打开的门220，也能维持出入口211的打开状态，因此容易向第二室28b内投入洗涤物。
在进行双重洗净模式的运转的情况下，在清洗过程和漂洗过程中，驱动部30的驱动形态被切换为双轴驱动形态。以使滚筒23内的洗涤物浸于水中的方式，向外筒20内蓄水至尚未到达投入口11的下缘的规定水位。在清洗过程中，向外筒20内蓄留含有洗涤剂的水，在漂洗过程中，向外筒20内蓄留含有柔顺剂的水。在进行多次漂洗过程的情况下，在最后的漂洗过程中使用柔顺剂。
在外筒20内蓄有水的状态下，驱动马达110交替进行正转和反转。由此，滚筒23和旋转体26以旋转体26的转速比滚筒23的转速快的状态交替进行正转和反转。此时，滚筒23以作用于滚筒23内的洗涤物的离心力小于重力的转速旋转。
在滚筒23的第一室28a内和第二室28b内，洗涤物被大型提升筋25a和小型提升筋25b提升又落下，由此被摔打至滚筒23的内周面。除此之外，在第二室28b内，洗涤物与旋转的旋转体26的突状部26a接触，洗涤物被突状部26a揉搓，或者洗涤物被突状部26a搅拌。而且，洗涤物被分隔板27的突起部224揉搓。
如此，在第一室28a内，洗涤物通过相对较低的机械力而被温和地清洗或者漂洗。此外，在第二室28b内，洗涤物通过相对较高的机械力而被强力地清洗或者漂洗。
在中间脱水过程和最终脱水过程中，驱动部30的驱动形态被切换为单轴驱动形态。驱动马达100即滚筒23和旋转体26以作用于滚筒23内的洗涤物的离 心力远大于重力的转速一体旋转。通过离心力的作用，第一室28a内和第二室28b内的洗涤物被按至滚筒23的内周面而被脱水。
在双重洗净模式的洗涤烘干运转的情况下，进行烘干过程。在烘干过程中，通过送风扇62的工作来使空气在外筒20与循环路61之间循环，通过加热器64的工作来对导入外筒20的空气进行加热而使其成为暖风。而且，在驱动部30的驱动形态为单轴驱动形态的状态下，滚筒23和旋转体26以作用于滚筒23内的洗涤物的离心力小于重力的转速一体进行正转和反转，洗涤物被翻滚。
从导入口24a导入至外筒20和滚筒23内的暖风吹拂至在第一室28a内翻滚的洗涤物，使第一室28a内的洗涤物烘干。被导入至第一室28a内的暖风经过设于分隔板27的多个通气口214被导入至第二室28b内。暖风吹拂至在第二室28b内翻滚的洗涤物，使第二室28b内的洗涤物烘干。在第一室28a内和第二室28b内从洗涤物中夺取了水分的暖风经过脱水孔23b向滚筒23外排出，从排气口20c返回至循环路61。在循环路61内，暖风在被加热器64加热之前经过冷却器63而被冷却器63除湿。
在进行单一洗净模式的运转的情况下，在清洗过程和漂洗过程中，驱动部30的驱动形态被切换为单轴驱动形态。在外筒20内蓄有水的状态下，驱动马达110交替进行正转和反转。由此，滚筒23和旋转体26以作用于滚筒23内的洗涤物的离心力小于重力的转速一体进行正转和反转。
在滚筒23的第一室28a内和第二室28b内，洗涤物被大型提升筋25a和小型提升筋25b提升又落下，由此被摔打至滚筒23的内周面。由此，在第一室28a内和第二室28b内，洗涤物被同等的机械力以同等的强度清洗或者漂洗。
关于中间脱水过程、最终脱水过程以及洗涤烘干运转中的烘干过程，与双重洗净模式的运转同样。
滚筒洗衣机1在烘干运转中包括双重烘干模式和单一烘干模式。滚筒洗衣机1准备了进行双重烘干模式的运转的运转进程和进行单一烘干模式的运转的运转进程。
在双重烘干模式的运转中，在滚筒23的第二室28b内和第一室28a内分别容纳敞领衬衫等容易产生褶皱的被烘干物和毛巾等不易产生褶皱的被烘干物。
在烘干过程中，驱动部30的驱动形态被切换为双轴驱动形态。从烘干装置60向滚筒23内供给暖风的同时，滚筒23和旋转体26以旋转体26的转速比滚筒23的转速快的状态交替进行正转和反转。此时，滚筒23以作用于滚筒23内的被烘干物的离心力小于重力的转速旋转。在第一室28a内和第二室28b内，被烘干物通过滚筒23的旋转而翻滚。此时，在第二室28b内，被烘干物的一部分与比滚筒23旋转得快的旋转体26的突状部26a接触而被拉扯，由此被烘干物能容易被伸展。由此，预期会减少被烘干物的起皱。
在单一烘干模式的运转中，被烘干物不进行分类地容纳于第一室28a内和第二室28b内。与洗涤烘干运转的情况同样，在烘干过程中，在驱动部30的驱动形态被切换为单轴驱动形态的状态下，滚筒23和旋转体26一体进行正转和反转，洗涤物被翻滚。
＜实施方式1的效果＞
根据本实施方式，滚筒洗衣机1具备：旋转体26，配置于滚筒23的后表面，在该旋转体26的表面具有与洗涤物接触的突状部26a；驱动部30，使滚筒23和旋转体26以不同的转速向相同的方向旋转；以及分隔板27，通过在前后方向上对滚筒23内进行分隔来将其分割成前侧的第一室28a和后侧的第二室28b。由此，在清洗过程中，在第一室28a内，能对洗涤物赋予仅由滚筒23的旋转产生的相对较低的机械力来将该洗涤物洗净，在第二室28b内，能对洗涤物赋予由滚筒23的旋转和旋转体26的旋转产生的相对较高的机械力来将该洗涤物洗净。
如此，根据本实施方式，能实现在滚筒23内同时进行利用滚筒23和旋转体26的机械力实现的洗净和仅利用滚筒23的机械力实现的洗净的双重洗净方式的滚筒洗衣机1。
而且，根据本实施方式，在滚筒洗衣机1中采用了如下构成，即，分隔板27包括：出入口211，用于使洗涤物出入于第二室28b内；以及门220，堵塞出入口211，能向第一室28a侧打开。由此，用户能打开门220并经过出入口211使洗涤物出入于第二室28b内。因此，用户在使洗涤物出入于第二室28b内时可以不逐一进行将分隔板27拆装于滚筒23的作业。
而且，根据本实施方式，在滚筒洗衣机1中采用了如下构成：门220能折叠成两折。由此，打开的门220不易成为障碍，能顺利地进行洗涤物向第二室28b内的出入。
而且，根据本实施方式，滚筒洗衣机1采用了如下构成：在分隔板27的第二室28b侧的面设有沿滚筒23的径向延伸的突起部224。由此，在清洗过程中，在第二室28b内翻滚的洗涤物被突起部224揉搓，因此能对洗涤物赋予更高的机械力，能良好地将洗涤物洗净。
而且，根据本实施方式，滚筒洗衣机1采用了如下构成：还具备向滚筒23内供给暖风的烘干装置60，在分隔板27设有供向滚筒23内供给的暖风经过的通气口214。由此，在烘干过程中，能将容易产生褶皱的被烘干物与不易产生褶皱的被烘干物分开容纳于第二室28b内，能对容易产生褶皱的被烘干物赋予由滚筒23的旋转和旋转体26的旋转产生的伸展效果，并且能通过从第一室28a经过通气口214流过来的暖风来将该被烘干物烘干。因此，能预期有效减少起皱并且将被烘干物烘干。
＜变形例1＞
图8是变形例1的滚筒23的侧视剖视图。图9的(a)和(b)分别是变形例1的装配有第一固定件310的分隔板27A的主视立体图和后视立体图。
在上述实施方式1中，具有能对折的门220的分隔板27配置于滚筒23内。
与此相对，在本变形例中，如图8所示，具有一整扇门220A的分隔板27A配置于滚筒23内。
如图9的(a)和(b)所示，本变形例的分隔板27A的门220A与上述实施方式1的门220同样通过铰链230与分隔主体210连结，并且具有门锁机构240和三个突起部224。
用户打开门220A，使洗涤物出入于第二室28b内。如图8的单点划线所示，打开的门220A从滚筒23的开口部23a稍微向前方伸出。
在本变形例中，分隔板27A的门220A为整扇门，因此门220A的刚性变高。因此，即使在滚筒23内翻滚的洗涤物强力撞击门220A，门220A也不易破损。
＜变形例2＞
图10的(a)是变形例2的表示分隔板27移动至最前方的状态的滚筒23的侧视剖视图，图10的(b)是变形例2的表示分隔板27移动至最后方的状态的滚筒23的侧视剖视图。图11的(a)是变形例2的在分隔板27的前方剖切而得到的滚筒23的主视剖视图，图11的(b)是变形例2的在分隔板27的后方剖切而得到的滚筒23的后视剖视图。
在上述实施方式1中，在滚筒23内，分隔板27被固定为无法向前后方向移动。
与此相对，在本变形例中，在滚筒23内设有移动机构400，分隔板27由该移动机构400保持为能向前后方向移动。
移动机构400由在滚筒23的内周面以沿周向具有大致120度的间隔的方式配置的两个大型提升筋410和一个小型提升筋420构成。即，移动机构400还具备作为在滚筒23旋转时将洗涤物提升的提升筋的功能。
大型提升筋410包括前部固定提升筋411、后部固定提升筋412以及移动提升筋413。
前部固定提升筋411具有前后方向上长的中空三棱柱状，后端面敞开。前部固定提升筋411配置于滚筒23内的前侧。后部固定提升筋412具有前后方向上长的中空三棱柱状。后部固定提升筋412配置于滚筒23内的后侧。
移动提升筋413具有前后方向上长的中空三棱柱状，后端面敞开。移动提升筋413中，其径向的外廓尺寸与前部固定提升筋411的径向的内廓尺寸大致相等，其径向的内廓尺寸与后部固定提升筋412的径向的外廓尺寸大致相等。
移动提升筋413从后方插入前部固定提升筋411的内部。此外，后部固定提升筋412从后方插入移动提升筋413的内部。由此，移动提升筋413由前部固定提升筋411和后部固定提升筋412引导而能向前后方向滑移。
小型提升筋420具有与大型提升筋410同样的构成，包括前部固定提升筋421、后部固定提升筋422以及移动提升筋423。
分隔板27通过第一固定件310固定于两个大型提升筋410的移动提升筋413 和小型提升筋420的移动提升筋423的后端部。此时，理想的是，第一固定件310与移动提升筋413、423通过螺丝、粘接剂来紧固，以便牢固地固定分隔板27。
当向后方按压分隔板27时，移动机构400的三个移动提升筋413、423向后方移动，分隔板27向后方移动。当向前方拉拽分隔板27时，三个移动提升筋413、423向前方移动，分隔板27向前方移动。需要说明的是，理想的是在分隔板27的前表面设有把手部，以便容易使分隔板27向前后方向移动。
如图10的(a)所示，在分隔板27移动至最前方时，第一室28a的空间最小，第二室28b的空间最大。如图10的(b)所示，在分隔板27移动至最后方时，分隔板27接近旋转体26，第二室28b消失，滚筒23内实质上仅具有第一室28a。
用户通过调整分隔板27在前后方向的位置，能根据分别容纳于第一室28a和第二室28b的洗涤物的量来调整第一室28a和第二室28b的大小。
需要说明的是，在进行不将洗涤物分类的单一洗净模式的情况下，若使分隔板27移动至最后方而将滚筒23内设为只有第一室28a的状态，则容易进行洗涤物向滚筒23内的出入。
在本变形例中，也可以使用上述变形例1的门220A为一整扇的分隔板27A来代替门220能折叠的分隔板27。
此外，在上述的例子中，即使在分隔板27移动至最前方的状态下，第一室28a也比第二室28b大。然而，也可以是，在分隔板27移动至最前方的状态下，第二室28b比第一室28a大。
＜变形例3＞
图12的(a)是变形例3的滚筒23的侧视剖视图。图12的(b)是变形例3的在分隔板27B的前方剖切而得到的滚筒23的主视剖视图。图13的(a)是变形例3的分隔板27B的后视图。图13的(b)是变形例3的其他分隔板27C的主视图。
在上述实施方式1中，分隔板27固定于滚筒23，无法拆装。分隔板27无法拆装，因此在分隔板27设有由门220开闭的出入口211。
相对于此，在本变形例中，分隔板27B能拆装地配置于滚筒23内。分隔板27B能拆装，因此不在分隔板27B设置出入口。
在滚筒23的内周面的前侧以沿周向具有大致120度的间隔的方式配置有具有大致三棱柱形状的两个前部大型提升筋25c和一个前部小型提升筋25d。此外，在滚筒23的内周面的后侧以沿周向具有大致120度的间隔的方式配置有具有大致三棱柱形状的三个后部小型提升筋25e。在两个前部大型提升筋25c和前部小型提升筋25d与三个后部小型提升筋25e之间，在前后方向上形成有比分隔板27B的厚度稍大的间隙。两个前部大型提升筋25c和前部小型提升筋25d与三个后部小型提升筋25e在周向上的位置错开大致60度。前部大型提升筋25c和前部小型提升筋25d相当于本发明的第一提升筋，后部小型提升筋25e相当于本发明的第二提升筋。
需要说明的是，配置于滚筒23的前侧和后侧的提升筋的个数只要为多个即可，可以为任意个数，提升筋的大小也可以为任意大小。
分隔板27B由硬质树脂材料形成，具有大致圆盘状，其外径与滚筒23的内径大致相等。分隔板27B具有通过两个铰链263来连结半圆板状的第一分隔构件261和第二分隔构件262而得到的构成，能折叠成两折。
在分隔板27B的中央部形成有在分隔板27B被分割的方向上排列的两个把手孔264。用户能通过将手指伸入两个把手孔264来抓住分隔板27B。
在分隔板27B的外周缘部，以沿周向隔出大致120度的间隔的方式形成有三个缺口部265，该缺口部265具有与后部小型提升筋25e的截面形状对应的V字形状。而且，在分隔板27B形成有多个通气口266。
在将分隔板27B装接于滚筒23内时，分隔板27B被折叠成两折，分隔板27B以使其正面不朝向滚筒23的正面的状态经过开口部23a被插入滚筒23内。折叠的分隔板27B在滚筒23内以其正面朝向滚筒23的正面的方式改变方向，并在三个后部小型提升筋25e的位置处被展开。此时，在分隔板27B的缺口部265收纳有后部小型提升筋25e。之后，分隔板27B被移动至两个前部大型提升筋25c和前部小型提升筋25d与三个后部小型提升筋25e之间的位置，并以使周向上的缺口部265与后部小型提升筋25e的位置错开的方式沿周向回转。
由此，如图12的(a)和(b)所示，分隔板27B由两个前部大型提升筋25c和前部小型提升筋25d与三个后部小型提升筋25e从前后方向夹持而呈被固定的状态。
分隔板27B能通过与装接时的顺序相反的顺序从滚筒23内卸下。
在进行双重洗净模式的运转的情况下，用户将受污严重等而希望强力洗净的洗涤物投入至成为第二室28b的滚筒23的纵深侧，之后向滚筒23内装接分隔板27B。之后，将其他洗涤物投入至滚筒23内的分隔板27B的前方即第一室28a内。当双重洗净模式的运转结束时，用户从第一室28a内取出洗涤物，之后将分隔板27B从滚筒23卸下，从滚筒23的后方取出剩余的洗涤物。
根据本变形例，在不进行双重洗净模式的运转等不需要分隔板27B的情况下，通过提前从滚筒23卸下分隔板27B，能不将滚筒23划分成两个空间，因此容易使洗涤物出入于滚筒23内。而且，根据本变形例，能利用设于滚筒23内的提升筋25c、25d、25e来实现分隔板27B能拆装的构成。
需要说明的是，可以使用图13的(b)的分隔板27C来代替分隔板27B。
分隔板27C具有大致圆盘状，其外径与滚筒23的内径大致相等。分隔板27C由软质树脂材料形成，能大幅变形。在分隔板27C以遍及整个面的方式形成有多个通气口267。
分隔板27C以能经过开口部23a的方式变形得较小而进入滚筒23内，并以由两个前部大型提升筋25c和前部小型提升筋25d与三个后部小型提升筋25e从前后方向夹持的方式配置于滚筒23内。
＜实施方式2＞
图14是表示滚筒烘干机2的构成的侧视剖视图。图15的(a)是旋转体550的主视图，图15的(b)是后轴承部531的主视图。图16的(a)和(b)是表示滚筒烘干机2的背面的一部分的图。图16的(a)表示背面罩512被卸下后的状态。
滚筒烘干机2具备方形的箱体510。箱体510由后表面开口的主体511和覆盖主体511的后表面的背面罩512构成。在箱体510的前表面形成有供衣物等被烘干物投入的圆形的投入口513。投入口513由开闭自如的门520覆盖。具有 圆筒状的前轴承部514从投入口513的外周缘向后方突出。

在箱体510，在背面罩512的后方以沿左右方向架设的方式装配有马达保持板533。在马达保持板533设有圆筒状的轴承部534。轴承部534贯通背面罩512和轴承保持板532而向前方延伸。
在箱体510内配置有容纳被烘干物的横轴型的滚筒540。在滚筒540，在前表面形成有圆形的前开口部540a，在后表面形成有圆形的后开口部540b。在滚筒540，在前开口部540a的外周缘设有向前方突出的圆筒状的前旋转轴541，在后开口部540b的外周缘设有向后方突出的圆筒状的后旋转轴542。
前轴承部514插入前旋转轴541内，后轴承部531插入后旋转轴542内，由此滚筒540以能绕水平轴旋转的方式由前轴承部514和后轴承部531支承。装配于前旋转轴541的内周面的前套环543与前轴承部514的外周面接触，装配于后旋转轴542的内周面的后套环544与后轴承部531的外周面接触。前套环543和后套环544具有低摩擦性和耐磨损性。
在滚筒540的前表面，在前开口部540a的周围呈环状地形成有由许多孔545a构成的吸气口545。在滚筒23的内周面以沿周向具有大致120度的间隔的方式设有具有大致三棱柱形状的两个大型提升筋546a和一个小型提升筋546b。
在滚筒540的后部，以堵塞后开口部540b的方式配置有旋转体550。旋转体550具有大致圆盘形状。在旋转体550的表面形成有从中央部呈辐射状延伸的多个突状部551。而且，在旋转体550形成有许多排气孔552。在旋转体550装配有驱动轴553。驱动轴553贯通形成于后轴承部531的开口部531a而向后方延伸，由马达保持板533的轴承部534支承为能旋转。
在马达保持板533固定有驱动马达560。旋转体550的驱动轴553连接于驱动马达560的转子。驱动马达560产生用于使旋转体550旋转的转矩。驱动马达560由马达罩561覆盖。
在后轴承部531的前表面，在外周缘侧形成有由以遍及整周的方式形成的 许多孔构成的排气口531b。在轴承保持板532、背面罩512以及马达保持板533也分别与后轴承部531的排气口531b对应地形成有由许多孔构成的排气口532a、512a、533a。
滚筒540的后开口部540b成为来自滚筒540的暖风的排气口，后开口部540b的后方成为暖风向机外的排气路。旋转体550和驱动马达560从滚筒烘干机2的正面观察时配置于滚筒540的后旋转轴542内。
在箱体510内的上部配置有滚筒马达570。在装配于滚筒马达570的皮带轮571与滚筒540之间卷绕有皮带572。滚筒马达570经由皮带572对滚筒540进行旋转驱动。
在箱体510内设有向滚筒540内供给暖风的暖风供给部580。暖风供给部580包括导风管道581、加热器582以及吸气扇583。
导风管道581配置于箱体510内的前上部，在其上端部具有导入口581a，在其下端部具有导出口581b。导出口581b朝向滚筒540的吸气口545开口。加热器582例如是半导体加热器，配置于导风管道581内。吸气扇583配置于箱体510内的后上部，包括风扇583a和对风扇583a进行旋转驱动的风扇马达583b。在箱体510的背面罩512，在吸气扇583的后方位置形成有由许多孔构成的吸气口512b。
在向滚筒540内供给暖风时，加热器582和吸气扇583工作。通过吸气扇583的工作，外部空气经过吸气口512b被吸入至箱体510内。吸入的空气流向前方而从导入口581a流入至导风管道581内。流过导风管道581内的空气即风被加热器582加热而成为暖风。暖风经过导出口581b从导风管道581流出，经过吸气口545被导入至滚筒540内。
在滚筒540内配置有分隔板590。滚筒540内被分隔板590在前后方向上分隔，由此被分割成前侧的第一室547a和后侧的第二室547b。分隔板590具有与上述实施方式1的分隔板27同样的构成，包括具有出入口211的分隔主体210和堵塞出入口211的能折叠的门220。在分隔主体210设有多个通气口214。分隔板590与分隔板27同样通过三个第一固定件310和三个第二固定件320而固定于三个提升筋546a、546b以及滚筒540的内周面。
滚筒烘干机2中进行各种运转进程的烘干运转。烘干运转中包括双重烘干模式和单一烘干模式。滚筒烘干机2准备了进行双重烘干模式的运转的运转进程和进行单一烘干模式的运转的运转进程。
在双重烘干模式的运转中，在滚筒540的第二室547b内和第一室547a内分别容纳敞领衬衫等容易产生褶皱的被烘干物和毛巾等不易产生褶皱的被烘干物。
在烘干运转中，从暖风供给部580向滚筒540内供给暖风，并且滚筒540和旋转体550以旋转体550的转速比滚筒540的转速快的状态旋转。
在第一室547a内和第二室547b内，被烘干物通过滚筒540的旋转而翻滚。此时，在第二室547b内，被烘干物的一部分与比滚筒540旋转得快的旋转体550的突状部551接触而被拉扯，由此被烘干物能容易地被伸展。由此，预期会减少被烘干物的起皱。
被导入至滚筒540内的暖风吹拂至在第一室547a内翻滚的洗涤物，将第一室547a内的洗涤物烘干。导入至第一室547a内的暖风经过设于分隔板590的多个通气口214被导入至第二室547b内。暖风吹拂至在第二室547b内翻滚的洗涤物，将第二室547b内的洗涤物烘干。暖风经过旋转体550的许多排气孔552和后轴承部531的排气口531b从滚筒540的后开口部540b排出，并经过轴承保持板532、背面罩512以及马达保持板533的排气口532a、512a、533a向机外排出。
在单一烘干模式的运转中，在第一室547a内和第二室547b内不进行分类地容纳被烘干物。从暖风供给部580向滚筒540内供给暖风，并且滚筒540和旋转体550以相同的转速一体旋转。由此，在滚筒540内，洗涤物一边翻滚一边被暖风烘干。
需要说明的是，驱动马达560和滚筒马达570构成使滚筒540和旋转体550以不同的转速向相同的方向旋转的驱动部。
＜实施方式2的效果＞
