Description

洗衣机 技术领域
本发明涉及洗衣机。
背景技术
在下述专利文献1所述的洗衣干衣机中，组装有被投入洗涤物的旋转桶部的外桶部经由倾斜旋转支承轴，由旋转支承板支承。在外桶部的底部，固定有用于使旋转桶部旋转的旋转驱动电机。旋转支承板经由吊棒，由洗衣干衣机的外框支承。外桶部设有转动操纵绳安装部，连在转动操纵绳安装部的操纵绳卷绕在设置于外框的倾斜转动电机的卷筒上。随着倾斜转动电机的旋转，操纵绳或上或下，由此，外桶部绕着倾斜旋转支承轴倾斜转动。由此，能在将洗涤物投入旋转桶部时使外桶部横向倾斜，在洗涤、漂洗、脱水时使外桶部立起来沿着垂直方向。
在专利文献1所述的洗衣干衣机中，用于给旋转驱动电机供电的配线、用于将蓄于外桶部的水排出的排水管之类的带状零件被设想为将外桶部和外框连结起来。考虑到洗涤运转中进行洗涤、脱水的外桶部的振动，这样的带状零件一般会有一定程度的松弛。特别是，可以想象在专利文献1所述的洗衣干衣机那样使外桶部倾斜转动的结构中，根据外桶部的转动范围的大小，带状零件的松弛会加大。但是，松弛大的带状零件可能会由于与旋转驱动电机等周围的零件发生干扰而造成损伤。

发明内容
发明所要解决的问题
本发明是基于该背景而完成的发明，其目的在于，提供一种洗衣机，其能 抑制从洗涤桶伸出并与洗涤桶之外的零件连接的带状零件的损伤。
用于解决问题的方案
本发明是一种洗衣机，包括：筒状的洗涤桶，收容洗涤物，并能以其轴线与垂直方向交叉的方式转动；以及带状零件，从所述洗涤桶的下部伸出并与所述洗涤桶之外的零件连接，所述洗涤桶的转动中心位于比所述洗涤桶的轴线方向上的所述洗涤桶的中心或所述洗涤桶的重心更低的位置。
此外，本发明的特征在于，包括：支承部，可转动地支承所述洗涤桶，所述带状零件从所述洗涤桶的下部伸出，并与所述支承部的下端部连接。
此外，本发明的特征在于，包括：机壳，收容所述洗涤桶；以及电气零件，固定于所述洗涤桶的下部，所述带状零件是从所述电气零件伸出的配线，与所述机壳的位于比所述电气零件更高位置的部分连接。
此外，本发明是一种洗衣机，包括：筒状的洗涤桶，收容洗涤物，并能以其轴线与垂直方向交叉的方式转动；以及带状零件，从所述洗涤桶的下部穿过所述洗涤桶的转动中心或所述转动中心的周围，向所述洗涤桶外伸出，与所述洗涤桶之外的零件连接。
此外，本发明的特征在于，包括：固定部，将所述带状零件的中途的至少一处部位固定在所述洗涤桶。
发明效果
根据本发明，在洗衣机中，筒状的洗涤桶能以其轴线与垂直方向交叉的方式转动，从洗涤桶的下部伸出的带状零件与洗涤桶之外的零件连接。
在该结构中，洗涤桶的转动中心位于比洗涤桶的轴线方向的洗涤桶的中心或洗涤桶的重心更低的位置。换句话说，洗涤桶的转动中心配置成偏向带状零件所在的洗涤桶的下部侧。在这种情况下，能缩小洗涤桶转动时洗涤桶的下部的转动范围。由此，由于能将从洗涤桶的下部伸出的带状零件的松弛抑制得较小，因此带状零件不容易与周围的零件发生干扰。其结果是，能抑制带状零件的损伤。
此外，根据本发明，从洗涤桶的下部伸出的带状零件与可转动地支承洗涤桶的支承部的下端部连接。在这种情况下，带状零件配置成与洗涤桶的下部连接的部分和与支承部连接的部分在上下方向上接近。由此，能将洗涤桶转动时 带状零件的移动范围抑制得较小。因此，由于能将从洗涤桶的下部到支承部的下端部的带状零件的松弛抑制得较小，因此带状零件不容易与周围的零件发生干扰。其结果是，能抑制带状零件的损伤。
此外，根据本发明，作为从固定于洗涤桶的下部的电气零件伸出的配线的带状零件，与收容洗涤桶的机壳的位于比电气零件更高位置的部分连接。在这种情况下，带状零件由于配置成在机壳和电气零件之间向上侧远离带状零件周围的电气零件，因此不容易与电气零件发生干扰。其结果是，能抑制带状零件的损伤。
此外，根据本发明，在洗衣机中，筒状的洗涤桶能以其轴线与垂直方向交叉的方式转动，从洗涤桶的下部伸出的带状零件与洗涤桶之外的零件连接。
在该结构中，带状零件穿过洗涤桶的转动中心或转动中心的周围，向洗涤桶外伸出。换句话说，带状零件从转动的洗涤桶的基本不移动的部分伸出并与洗涤桶之外的零件连接。由此，能将洗涤桶转动时带状零件的移动范围抑制得较小。因此，由于能将带状零件的松弛抑制得较小，因此带状零件不容易与周围的零件发生干扰。其结果是，能抑制带状零件的损伤。
此外，根据本发明，由于带状零件的中途的至少一处部位通过固定部固定于洗涤桶，因此能进一步将洗涤桶转动时带状零件的移动范围抑制得更小。因此，由于能进一步将带状零件的松弛抑制得更小，因此带状零件不容易与周围的零件发生干扰。其结果是，能进一步抑制带状零件的损伤。

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衣机1的示意性立体图。将图1中的上下方向称为洗衣机1的上下方向Z，将图1中的左右方向称为洗衣机1的前后方向Y，将与图1的纸面大致正交的横方向称为左右方向X。上下方向Z也即垂直方向。上下方向Z当中，将上侧称为上侧Z1，将下侧称为下侧Z2。前后方向Y当中，将图1中的右侧称为前侧Y1，将图1中的左侧称为后侧Y2。左右方向X当中，将图1的纸面的表侧称为左侧X1，将图1的纸面的里侧称为右侧X2。
在洗衣机1中，虽然也包括具有干衣功能的洗衣干衣机，但是以下，以省略了干衣功能，只执行洗涤运转的洗衣机为例对洗衣机1进行说明。洗涤运转包括洗涤过程、漂洗过程、以及脱水过程。洗衣机1包括：机壳2、收容于机壳2内的洗涤桶3、支承部4、吊棒5、转动部6、锁定解除机构7以及驱动机构8。
机壳2为例如金属制，形成为箱状。在机壳2，设置有连接前表面2A和上表面2B的连结面2C。连结面2C是例如随着朝向前侧Y1而下降的倾斜面。用于向洗衣机1内投入取出洗涤物的出入口(未图示)以跨连前表面2A和连结面2C的方式形成。
洗涤桶3具有筒状的整体形状，包括外桶10和内桶11。外桶10为例如树脂制，形成为有底圆筒状。在洗涤过程、漂洗过程中，外桶10内蓄有水。通过外桶10的圆心的虚拟直线是外桶10的轴线J。有底圆筒状的外桶10具有沿着轴线J配置的大致圆筒状的圆周壁12和沿着轴线J从下侧Z2堵塞圆周壁12的中空部分的圆盘状的底壁13。在洗涤桶3的与底壁13相反侧的上端部，形成有由圆周壁12的上端缘围成的圆形状的开口10A。开口10A供投入取出洗衣机1内的洗涤物通过。在圆周壁12的左右侧面，逐一设置有向左右方向X的外侧突出的金属制的转动轴14。图1中，只图示出左侧X1的转动轴14。这左右一对转动轴14从左右方向X观察时配置于同一位置。
内桶11为例如金属制，形成为比外桶10小一圈的有底圆筒状。洗涤物收容于内桶11。在内桶11的与底壁(未图示)相反侧的上端部，形成有供收容于内桶11内的洗涤物通过的圆形开口11A。内桶11同轴状地收容于外桶10内。因此，内桶11的轴线即上述的轴线J。轴线J也是洗涤桶3整体的轴线。将轴线J延伸的方向称为洗涤桶3的轴线方向D。在内桶11收容于外桶10内的状态下，内桶11的开口11A位于外桶10的开口10A的内侧。开口10A以及开口11A与机壳2的出入口(未图示)对置，由此，能向内桶11内投入取出洗涤物。在内桶11的圆周壁11B以及底壁，形成有多个贯通孔11C，外桶10内的水经由这些贯通孔11C，往来于外桶10与内桶11之间。因此，外桶10内的水位与内桶11内的水位一致。在洗涤运转中，内桶11通过接受来自设置于机壳2内的电机15(参照后述的图2)的驱动力，绕轴线J旋转。
支承部4为金属制，包括左右一对侧板16和架设于这对侧板16的下端部之间的梁构件17。各个侧板16形成为从左右方向X观察呈大致矩形状，并且在左右方向X上薄。在一对侧板16之间，配置有洗涤桶3。
对于洗涤桶3的外桶10而言，向左侧X1突出的转动轴14贯通左侧X1的侧板16，经由轴承(未图示)由左侧X1的侧板16以能转动的方式支承。对于外桶10而言，向右侧X2突出的转动轴14(未图示)贯通右侧X2的侧板16，经由轴承(未图示)由右侧X2的侧板16以能转动的方式支承。由此，洗涤桶3由支承部4支承，能以轴线J与上下方向Z交叉的方式绕转动轴14转动。具体地说，洗涤桶3随着电机15(参照图2)转动，此时，轴线J相对于上下方向Z向前后方向Y倾斜。将洗涤桶3的转动方向称为转动方向K。外桶10的圆周壁12的在轴线方向D上比转动轴14更靠近底壁13侧的部分和底壁13构成洗涤桶3的下部3A。
沿着上下方向Z延伸的虚拟基准轴L与轴线J的呈锐角的交叉角度为洗涤桶3相对于基准轴L的转动角度θ。转动角度θ越小，洗涤桶3越接近直立姿势，转动角度θ越大，洗涤桶3越是以外桶10的开口10A以及内桶11的开口11A朝向前侧Y1的方式，呈向前侧Y1倾斜的姿势。转动角度θ能以例如0度、15度、30度、45度、60度这五档进行变更。在这种情况下，作为在洗衣机1中的应用的一个例子，当在洗涤运转开始时将洗涤物投入洗涤桶3时，以使洗涤物 的投入变得容易的方式将转动角度θ设定为45度，然后，在检测洗涤物的负荷量或对洗涤桶3进行供水的情况下，转动角度θ设定为0度。然后，在洗涤过程、漂洗过程中，为了促进内桶11内的洗涤物的位置交替以实现高效的洗涤、漂洗，将转动角度θ设定为在0度和60度之间变动。
在左侧X1的侧板16的比转动轴14更靠近下侧Z2的区域，形成有沿着左右方向X贯通该侧板16的开口16A。开口16A形成为在前后方向Y上长的大致长方形。在各个侧板16的前端缘以及后端缘，设置有向前后方向Y的外侧突出的支承部18。支承部18既可以形成为与侧板16一体，也可以作为例如树脂制的其他零件安装于侧板16。
吊棒5形成为下端部具有摩擦阻尼器19的棒状。吊棒5存在四根，在机壳2内逐一配置于从上侧Z1观察俯视时的四角。这些吊棒5处于从机壳2的上部，详细地说是从构成机壳2的一部分的金属制外框(未图示)悬吊的状态。在左侧X1前后排列的两根吊棒5当中，前侧Y1的吊棒5的下端部与左侧X1的侧板16的前侧Y1的支承部18连结，后侧Y2的吊棒5的下端部与左侧X1的侧板16的后侧Y2的支承部18连结。在右侧X2前后排列的两根吊棒5当中，前侧Y1的吊棒5的下端部与右侧X2的侧板16的前侧Y1的支承部18连结，后侧Y2的吊棒5(未图示)的下端部与右侧X2的侧板16的后侧Y2的支承部18(未图示)连结。由此，具有侧板16的支承部4、由支承部4支承的洗涤桶3、以及使内桶11旋转的电机15(参照图2)经由吊棒5，由机壳2弹性支承。
转动部6是左右方向X上薄，从左右方向X观察形成为向前侧Y1膨出的大致扇形的金属制的板。转动部6具有形成为沿着转动方向K的圆弧状并向前侧Y1膨出的外周缘6A。在转动部6的与外周缘6A的曲率中心一致的位置处，形成有沿着左右方向X贯通转动部6的贯通孔6B。在外周缘6A，形成有多个凹部6C，此处为五个。这些凹部6C向贯通孔6B凹陷并且沿着左右方向X贯通转动部6，并沿着转动方向K排列配置。相邻凹部6C的间隔既可以固定，也可以因转动部6的位置而异。在本实施方式中，与转动角度θ设定为0度、15度、30度、45度、60度相对应，其他的相邻凹部6C之间的间隔一律为15度。
转动部6配置为比左侧X1的侧板16更靠近左侧X1。向外桶10的左侧X1突出并贯通左侧X1的侧板16的转动轴14插入转动部6的贯通孔6B，固定于 转动部6。由此，转动部6经由转动轴14，以能一体转动的方式连结于外桶10。
在图1中的姿势下的转动部6，在外周缘6A的后端，一体地设置有往下侧Z2突出，具体而言往以贯通孔6B为中心的转动部6的径向R的外侧突出的延设部6D。在延设部6D，形成有径向R上长并且沿着左右方向X贯通延设部6D的引导孔6E。引导孔6E在上下方向Z上与左侧X1的侧板16的开口16A位于同一位置，始终从左侧X1与开口16A对置。
锁定解除机构7固定于左侧X1的侧板16的左侧面。锁定解除机构7包括主体部21和锁定部22。在主体部21，设置有由螺线管等构成的促动器(未图示)。锁定部22形成为从主体部21向后侧Y2突出的凸状，由主体部21以能向前后方向Y滑动的方式支承。主体部21的促动器工作，从而使锁定部22在向最后侧Y2进入的进入位置和向最前侧Y1退出的退出位置之间滑动。图1的锁定部22位于进入位置，并处于嵌入转动方向K上同一位置的凹部6C的状态。由此，转动部6以及洗涤桶3的转动被锁定。在该状态下，当锁定部22退出到退出位置时，由于锁定部22离开凹部6C，因此转动部6以及洗涤桶3的锁定被解除。
驱动机构8包括：框架23、一对支承部24、螺纹轴25、电机26、联轴器27、螺母构件28、以及传感器29。
框架23通过将金属板折曲为例如曲柄状而形成，以从右侧X2覆盖左侧X1的侧板16的开口16A的开口的方式从右侧X2固定于该侧板16。一对支承部24以沿着前后方向Y远离排列的状态固定于框架23，并处于从框架23向左侧X1突出的状态。螺纹轴25形成为沿着前后方向Y细长地延伸的圆柱状，在其外周面的几乎整个区域，形成有螺旋状延伸的螺牙25A。螺纹轴25由设置于前后一对支承部24的轴承30，以能旋转的方式两端支承。
电机26是普通的电动电机，具有向后侧Y2突出并与螺纹轴25同轴状配置的输出轴31。螺纹轴25的前端部和输出轴31通过联轴器27以能一体旋转的方式连结。因此，当电机26驱动从而输出轴31进行旋转时，螺纹轴25与输出轴31一体旋转。螺母构件28具有在内周面形成有螺旋状延伸的螺牙(未图示)的环状的螺母，以该螺牙与螺纹轴25的螺牙25A相互螺纹连接的方式，外嵌于螺纹轴25。当螺纹轴25随着电机26的驱动而旋转时，随着螺纹轴25的旋转，螺 母构件28整体沿着螺纹轴25的轴向即前后方向Y移动。螺母构件28通过固定插入转动部6的延设部6D的连结销32，经由连结销32，与转动部6连结。因此，当螺母构件28随着螺纹轴25的旋转沿着前后方向Y进行移动时，转动部6通过螺母构件28被拉向前后方向Y，从而随着洗涤桶3转动。
传感器29是用于根据前后方向Y的螺母构件28的位置检测洗涤桶3的转动角度θ的传感器，作为传感器29，能使用光传感器等光学传感器。在这种情况下，传感器29设置为与转动部6的凹部6C的数量相同，以沿着前后方向Y排列的状态固定于框架23。在各个传感器29，形成有沿着前后方向Y贯通传感器29的槽29A，传感器29处于检测光沿着上下方向Z横切槽29A的状态。在螺母构件28，设置有被称为限位部的杆状的被检测部28A。当转动角度θ为0度、15度、30度、45度、60度中的任一个角度时，被检测部28A嵌入任一个传感器29的槽29A从而遮挡该槽29A的检测光。因此，五个传感器29统一检测转动角度θ是0度、15度、30度、45度、60度中的哪一个角度。
图2是上述的转动角度θ为0度的状态即洗涤桶3直立状态下的洗衣机1的主要部分的左视图。图3是洗涤桶3倾斜的状态，例如转动角度θ为60度状态下的洗衣机1的主要部分的左视图。参照图2，如上所述用于产生使内桶11旋转的驱动力的电机15是洗衣机1所包含的电气零件中的一个，从下侧Z2固定于外桶10的底壁13。电机15的输出轴(未图示)经由离合器机构等传递机构33与内桶11连结。对电机15的重心赋予附图标记G1。另一方面，对洗涤桶3整体的重心赋予附图标记G2。重心G2既可以如本实施方式那样是单独的洗涤桶3的重心，也可以是水、洗涤物收容于洗涤桶3的状态下的水和洗涤物和洗涤桶3的集合体的重心。
无论是在上述哪种定义重心G2的情况下，电机15的重心G1和洗涤桶3的重心G2都配置于洗涤桶3的轴线J上。而且，作为洗涤桶3的转动中心的转动轴14配置于比重心G2更低的位置。具体而言，从左右方向X观察，在轴线J上，转动轴14配置于重心G1与重心G2之间。无论转动角度θ是多少，重心G1以及重心G2各自与转动轴14的位置关系都相同(参照图3)。
在固定于外桶10的底壁13的电机15，连接有从固定于机壳2的电源基板(未图示)延伸并对电机15供电的供电线、从固定于机壳2的控制基板(未图 示)延伸并向电机15发送控制信号的信号线即配线40。此外，在底壁13，设置有用于将蓄于外桶10的水排到机外的软管状的排水路41。排水路41贯通机壳2，并被拉出到机壳2外。这样，配线40、排水路41这些带状零件42从底壁13也就是洗涤桶3的下部3A伸出，与洗涤桶3之外的零件连接。洗涤桶3之外的零件是指电源基板、控制基板、机壳2之类始终不动的零件。
洗涤桶3的重心G2既可以是轴线方向D上的洗涤桶3整体的中心C，也可以重心G2与中心C不一致。无论哪种情况，作为洗涤桶3的转动中心的转动轴14配置在比洗涤桶3的中心C以及重心G2的至少一方更低的位置即可。这样，转动轴14由于位于比洗涤桶3的中心C或重心G2更低的位置，因此在洗涤桶3中配置为偏向带状零件42所在的下部3A侧。在这种情况下，能缩小洗涤桶3转动时洗涤桶3的下部3A的转动范围。由此，由于能将从洗涤桶3的下部3A伸出的带状零件42的松弛抑制得较小，因此带状零件42不容易与电机15、支承部4这些周围的零件发生干扰。其结果是，能抑制带状零件42的损伤。
进而，在如上所述转动轴14配置于重心G1与重心G2之间的情况下，由于洗涤桶3和电机15的集合体的平衡稳定，因此用很小的力就能使洗涤桶3转动，也能用很小的力稳定转动后倾斜姿势的洗涤桶3。因此，能减小使洗涤桶3转动的驱动机构8的负担、锁定洗涤桶3的转动的锁定解除机构7的负担(参照图1)。
以下，作为带状零件42的一个例子，着重对配线40进行了说明，但是关于配线40的以下的内容也能用于排水路41。配线40从洗涤桶3的下部3A的电机15伸出，与支承部4的右侧X2的侧板16的下端部16B连接。下端部16B也是支承部4整体的下端部。配线40从左右贯通下端部16B，与机壳2的电源基板(未图示)、控制基板(未图示)连接。
在这种情况下，带状零件42以与洗涤桶3的下部3A连接的部分42A和与支承部4的下端部16B连接的部分42B在上下方向Z上靠近的方式配置。由此，能将洗涤桶3转动时带状零件42的移动范围抑制得较小。因此，由于能将从洗涤桶3的下部3A到侧板16的下端部16B的带状零件42的松弛抑制得较小，带状零件42不容易与周围的零件发生干扰。其结果是，能抑制带状零件42的损伤。
图4是洗涤桶3直立状态下第一变形例的洗衣机1的主要部分的左视图。图5是洗涤桶3倾斜状态下第一变形例的洗衣机的主要部分的左视图。在图4以及5中，对与图1～图3中已说明的部分相同的部分赋予相同的标记，并省略关于该部分的说明(后述的图6以及图7也同样)。在图4以及图5所示的第一变形例中，从电机15伸出的配线40不与侧板16连接，而是从左右一对侧板16之间的空间43向后侧Y2拽出，直接与机壳2的后壁2D连接。具体而言，配线40与后壁2D的位于比电机15更高的位置的部分2E连接。
在这种情况下，由于作为带状零件42的配线40以在机壳2与电机15之间向上侧Z1远离带状零件42的周围的电机15的方式配置，因此在洗涤桶3倾斜时配线40不容易与电机15发生干扰。其结果是，能抑制配线40的损伤。
图6是第二变形例的洗衣机1的纵截面主视图。关于第二变形例，左右一对转动轴14中的至少一方形成为中空。在图6中，左侧X1的转动轴14形成为中空。具体而言，在该转动轴14，形成有从外桶10的底壁13侧的入口14A向轴线方向D延伸后向左侧X1折曲成大致直角并从转动轴14的左端面的出口14B露出的大致L字状的贯通孔14C(也参照图6中用虚线圆包围的部分的放大图)。以在图6中洗涤桶3直立的状态为基准，配线40从电机15向上侧Z1拉出并沿着洗涤桶3的下部3A，按照入口14A以及出口14B的顺序穿过左侧X1的转动轴14的贯通孔14C并从该转动轴14向左侧X1伸出，由此延伸到洗涤桶3外。
换句话说，配线40从几乎不在转动的洗涤桶3中移动的部分即转动轴14伸出并与洗涤桶3之外的零件连接。由此，能将洗涤桶3转动时配线40的移动范围抑制得较小。因此，由于即使不采用上述的实施方式(参照图1～图3)以及第一变形例(参照图4以及图5)那样转动轴14配置于比洗涤桶3的重心G2、中心C更低的位置的结构，也能将配线40的松弛抑制得较小，因此配线40不容易与周围的零件发生干扰。其结果是，能抑制配线40的损伤。当然，在变形例2中，也可以将转动轴14配置于比重心G2、中心C更低的位置，此时，由于能进一步将配线40的松弛抑制得更小，因此能进一步抑制配线40的损伤。
在洗涤桶3的下部3A的表面，设置有固定部44。固定部44的数量可以任意设定，图6中，在外桶10的圆周壁12和底壁13各设一个，合计设置有两个。 固定部44为例如环状。配线40的中途部分插入固定部44。由此，由于配线40的中途的至少一处部位固定于洗涤桶3，因此能进一步将洗涤桶3转动时的配线40的移动范围抑制得较小。因此，由于能进一步将配线40的松弛抑制得较小，因此配线40通过与洗涤桶3一体化，不容易与侧板16等周围的零件发生干扰。其结果是，能进一步抑制配线40的损伤。需要说明的是，固定部44也可以设置于从电机15，严格来说设置于形成为从下侧Z2安装于底壁13的大致U字状并在内侧收容电机15的支架45(参照图4)。
图7是第三变形例的洗衣机1的纵截面主视图。关于第三变形例，支承部4的一对侧板16中的至少一方在转动轴14的周围形成有贯通孔16C(也参照图7中由虚线圆包围的部分的放大图)。图7中，在左侧X1的侧板16形成有贯通孔16C。将图7中洗涤桶3直立的状态作为基准，配线40从电机15向上侧Z1拉出并沿着洗涤桶3的下部3A穿过左侧X1的侧板16的转动轴14的周围的贯通孔16C，从该侧板16向左侧X1伸出，由此，延伸到洗涤桶3外。需要说明的是，为了使插入贯通孔16C的配线40不影响转动部6、锁定解除机构7、驱动机构8(参照图1)的工作，贯通孔16C形成在尽量靠近转动轴14的位置。
在这种情况下，与变形例2一样，由于配线40从几乎不在转动的洗涤桶3中移动的部分伸出并与洗涤桶3之外的零件连接，因此能将洗涤桶3转动时的配线40的移动范围抑制得较小。因此，由于能将配线40的松弛抑制得较小，因此配线40不容易与周围的零件发生干扰，从而能抑制配线40的损伤。在变形例3中，与变形例2一样，为了进一步将配线40的松弛抑制得更小，可以将转动轴14配置在比洗涤桶3的重心G2、中心C更低的位置。
本发明不局限于以上所说明的实施方式，可以在权利要求记载的范围内进行各种变更。
例如，作为洗涤桶3中与配线40连接的电气零件，除了上述的电机15之外，还能例举出用于检测外桶10内的水位等的传感器、上述传递机构33。
此外，只要能在电机26的驱动停止时限制螺母构件28在前后方向Y上的移动即洗涤桶3的转动，也可以省略锁定解除机构7、转动部6的凹部6C。由此，能对转动角度θ进行无级调整。
