发明内容
发明所要解决的问题
由于专利文献1所述的洗衣机的吊棒，难以充分吸收外桶的振动，因而需要增大机框或者缩小洗涤脱水桶，使得不会因振动时的外桶与机框接触而产生噪音。如果增大机框，则洗衣机变大，如果缩小洗涤脱水桶，则能由洗衣机洗涤的洗涤物的容量变少。
本发明是基于该背景而完成的发明，其目的在于提供一种能以不减小洗涤物的容量的方式实现小型化并实现振动和噪音的减弱的洗衣机。
用于解决问题的方案
本发明为一种洗衣机，包括：机壳，具有框架；洗涤桶，具有收容洗涤物并被驱动旋转的脱水桶，并配置于所述机壳内；以及四个支承构件，形成为从 所述框架悬吊并连结于所述洗涤桶的棒状，弹性支承所述洗涤桶，所述四个支承构件中，相邻的第一对支承构件比第二对支承构件短，所述第二对支承构件在沿相对于所述第一对支承构件的排列方向的正交方向远离所述第一对支承构件的位置，沿所述排列方向相邻，所述第一对支承构件的上端彼此的间隔比所述第二对支承构件的上端彼此的间隔大，所述第一对支承构件以相互间隔越向下侧越窄的方式相对于垂直方向倾斜，所述第二对支承构件以相互间隔越向下侧越宽的方式相对于垂直方向倾斜。
此外，本发明的特征在于，所述正交方向为所述洗衣机的前后方向，所述第一对支承构件配置于所述第二对支承构件的前侧。
此外，本发明的特征在于，所述框架包括位于所述机壳的前表面部且越向上侧越往前侧弯曲的前侧纵支柱。
此外，本发明的特征在于，所述洗涤桶可以绕沿水平方向延伸的转动轴转动。
发明效果
根据本发明，形成为从机壳的框架悬吊的棒状的四个支承构件连结于洗涤桶。四个支承构件中，第一对支承构件相邻，剩下的第二对支承构件在沿相对于第一对支承构件的排列方向的正交方向远离第一对支承构件的位置，沿所述排列方向相邻。
第一对支承构件比第二对支承构件短，第一对支承构件的上端彼此的间隔比第二对支承构件的上端彼此的间隔大。而且，第一对支承构件以相互间隔越向下侧越窄的方式相对于垂直方向倾斜，第二对支承构件以相互间隔越向下侧越宽的方式相对于垂直方向倾斜。这样的结构的四个支承构件弹性支承洗涤桶，由此，因脱水桶的旋转导致的洗涤桶的振动减弱，因振动产生的洗涤桶的摆幅变小。由此，振动中的洗涤桶与机壳接触的情况被抑制。因此，实现因洗涤桶与机壳接触而产生的噪音的减弱。此外，由于洗涤桶的摆幅小，因而能不改变洗涤桶的大小而是通过缩小机壳来缩小洗涤桶与机壳的间隔。由此，能以不减小洗涤桶中洗涤物的容量的方式实现洗衣机的小型化。
此外，根据本发明，在洗衣机的前后方向，第一对支承构件配置于第二对支承构件的前侧，由此能使上端彼此的间隔相对较窄的第二对支承构件所在的洗衣机的后部宽度缩小，因此能实现洗衣机的进一步小型化。
此外，根据本发明，框架中位于机壳的前表面部且越向上侧越往前侧弯曲的前侧纵支柱具有弹性。因此，能通过前侧纵支柱的弹性变形来吸收经由支承构件传给框架的洗涤桶的振动。由此，能抑制因脱水桶的旋转而产生的洗涤桶的振动传给地面等安置面，进一步减弱振动和噪音。
此外，根据本发明，洗涤桶可以绕沿水平方向延伸的转动轴转动，这种结构的洗衣机能以不减小洗涤物的容量的方式实现小型化并实现振动和噪音的减弱。

四个纵支柱12逐一配置于从上侧Z1观察的俯视时的机壳2的四角，并向上下方向Z延伸。四个纵支柱12包括位于机壳2的前表面部2A的左右一对前侧纵支柱12A和位于机壳2的后表面部2B的左右一对后侧纵支柱12B。各个前侧纵支柱12A和各个后侧纵支柱12B下端的高度位置相同，但各个前侧纵支柱12A的上端位于比各个后侧纵支柱12B的上端低的位置。
各个前侧纵支柱12A在从下端沿上下方向Z直线状延伸到中途之后，向前侧Y1倾斜直至上端。因此，各个前侧纵支柱12A以越向上侧Z1越往前侧Y1弯曲的方式形成为弓形。此外，机壳2的前表面部2A，具体地说，装饰盖11的位于前表面部2A的部分沿着各个前侧纵支柱12A以越向上侧Z1越往前侧Y1弯曲的方式形成。由此，在前表面部2A的周围，洗衣机1形成有收容从前侧Y1利用洗衣机的使用者的膝盖以下部位的空间S。因此，由于使用者，特别是乘坐轮椅的使用者能以贴近洗衣机1的状态操作洗衣机1的操作部(未图示)或投取洗涤物，因而使用方便。各个前侧纵支柱12A比各个后侧纵支柱12B粗。
各个后侧纵支柱12B遍及从下端到上端的整个区域沿上下方向Z直线状延伸。一对后侧纵支柱12B的左右间隔比一对前侧纵支柱12A的左右间隔窄。因此，左侧X1的后侧纵支柱12B以比左侧X1的前侧纵支柱12A更偏向右侧X2的方式配置，右侧X2的后侧纵支柱12B以比右侧X2的前侧纵支柱12A更偏向左侧X1的方式配置。
两个第一上侧横支柱13在左右方向X上直线状延伸并前后并排地配置。前侧Y1的第一上侧横支柱13架设于两个前侧纵支柱12A的上端之间，后侧Y2的第一上侧横支柱13架设于两个后侧纵支柱12B的上端之间。
两个第二上侧横支柱14前后延伸并左右并排地配置。左侧X1的第二上侧横支柱14架设于左侧X1的前侧纵支柱12A以及后侧纵支柱12B的上端之间， 并且架设于两个第一上侧横支柱13的左端之间。右侧X2的第二上侧横支柱14架设于右侧X2的前侧纵支柱12A以及后侧纵支柱12B的上端之间，并且架设于两个第一上侧横支柱13的右端之间。两个第二上侧横支柱14从前侧纵支柱12A的上端向上侧Z1倾斜的同时向后侧Y2延伸，并以在中途相互贴近的方式弯曲成曲柄状，之后向下侧Z2倾斜的同时向后侧Y2延伸，连接于后侧纵支柱12B的上端。机壳2的上表面部2C，具体地说，装饰盖11的位于上表面部2C的部分以沿着第二上侧横支柱14的形状的方式，从前面部2A的上端向上侧Z1倾斜的同时向后侧Y2延伸，而上表面部2C的后端部向下侧Z2倾斜的同时向后侧Y2延伸，连接于后表面部2B的上端。在上表面部2C的比后端部更向前侧Y1倾斜的部分，设置有用于向洗衣机1投取洗涤物的出入口(未图示)和开闭该出入口的门17。
各个第二上侧横支柱14中，在比前端部稍微偏向后侧Y2的部分和后端部，分别设置有一个连结部18。也就是说，连结部18共计有四个，包括左右一对前侧连结部18A和左右一对后侧连结部18B。各个连结部18形成为金属制的板状。连结部18可以一体地设置于第二上侧横支柱14，也可以作为独立部件重叠在第二上侧横支柱14上并用螺钉等固定。在各个连结部18，形成有沿上下方向Z贯通连结部18并从第二上侧横支柱14向下侧Z2露出的圆形的贯通孔18C。连结部18的切出贯通孔18C的内周面18D形成为越向下侧Z2越窄的球状。
两个第一下侧横支柱15沿左右方向X直线状延伸并前后并排地配置。前侧Y1的第一下侧横支柱15架设于两个前侧纵支柱12A的下端之间，后侧Y2的第一下侧横支柱15架设于两个后侧纵支柱12B的下端之间。
两个第二下侧横支柱16前后延伸并左右并排地配置。左侧X1的第二下侧横支柱16架设于左侧X1的前侧纵支柱12A以及后侧纵支柱12B的下端之间，并且架设于两个第一下侧横支柱15的左端之间。右侧X2的第二下侧横支柱16架设于右侧X2的前侧纵支柱12A以及后侧纵支柱12B的下端之间，并且架设于两个第一下侧横支柱15的右端之间。左侧X1的第二下侧横支柱16的左端缘从前侧纵支柱12A的下端沿前后方向Y直线状延伸，并在中途向右侧X2弯曲之后直线状地向后侧Y2延伸，连接于后侧纵支柱12B的下端。右侧X2的第二下侧横支柱16的右端缘(未图示)从前侧纵支柱12A的下端沿前后方向Y直线状延伸，并在中途向左侧X1弯曲之后，直线状地向后侧Y2延伸，连接于后 侧纵支柱12B的下端。在各个第二下侧横支柱16的下表面部的前后的端部，设置有与安置洗衣机1的地板面等安置面接触的腿部19或轮子20。
在这样的框架10的内侧，形成有收容洗涤桶3、电机4、支承构件9、支承框架5、连结部7以及驱动机构6的大致长方体状的收容空间10A。此外，在框架10，形成有由在左右方向X上位于相同位置的前侧纵支柱12A、后侧纵支柱12B、第二上侧横支柱14以及第二下侧横支柱16围起的大致矩形的侧面开口部10B。侧面开口部10B以从左右包夹收容空间10A的方式成对设置。各个侧面开口部10B具有从左右方向X观察时与收容空间10A大致一致的形状和大小，其上端的大部沿第二上侧横支柱14向前侧Y1并向下侧Z2倾斜。
洗涤桶3具有外桶25和脱水桶26。外桶25例如为树脂制并形成为有底圆筒状，能在内部蓄水。外桶25具有沿图1中大致上下方向Z配置的大致圆筒状的圆周壁27和从下侧Z2堵住圆周壁27的中空部分的圆盘状的底壁28(参照图3)。在外桶25，形成有由圆周壁27的上端边缘围出的开口25A。开口25A位于机壳2的上表面部2C的所述出入口(未图示)的正下方，使外桶25的内部与出入口连通。
脱水桶26例如为金属制，形成为比外桶25小一圈的有底圆筒状，同轴状地收容在外桶25内。脱水桶26能在内部收容洗涤物。在脱水桶26的上表面，形成有从正下方与外桶25的开口25A连通的开口26A。洗衣机1的使用者经由所述的出入口(未图示)、开口25A以及开口26A向脱水桶26投取洗涤物。在脱水桶26，形成有多个贯通孔26B，外桶25内的水能经由这些贯通孔26B，往来于外桶25与脱水桶26之间。因此，外桶25内的水位与脱水桶26内的水位一致。在脱水桶26的底壁的与脱水桶26的圆心一致的部分，设置有向下侧Z2突出的旋转轴(未图示)。该旋转轴由外桶25的底壁28可旋转地支承，由此，脱水桶26可绕旋转轴旋转。
电机4(参照图3)是电动马达。电机4从下侧Z2固定于外桶25的底壁28。电机4的驱动力传递到脱水桶26的旋转轴(未图示)。由此，脱水桶26被驱动旋转。尤其是在脱水过程中，为了使离心力作用于洗涤物从而有效地进行脱水，脱水桶26高速旋转。需要说明的是，也可以在脱水桶26内设置为了搅拌收容的洗涤物而进行旋转的波轮(未图示)，并在洗涤过程、漂洗过程中使电机4的驱动力传递到波轮。
参照去掉支承框架5等重要部位之后的立体图即图2，支承框架5包括左右一对侧板30和架设于这一对侧板30之间的前后一对连结板31。各侧板30具有在左右方向X上一致的板厚方向，从左右方向X观察形成为大致矩形。各个侧板30的上端部向左右方向X的洗衣机1的外侧弯曲，前端部、后端部以及下端部向左右方向X的洗衣机1的中央侧弯曲。各个连结板31具有在前后方向Y上一致的板厚方向，从前后方向Y观察形成为大致U字状。前侧Y1的连结板31架设于左右的侧板30的前端部之间，通过螺钉等紧固构件32从前侧固定于各个侧板30的前端部的上下方向Z上的大部区域。此外，前侧Y1的连结板31的下端部31A向后侧Y2弯曲成大致L字状，并以从下侧Z2与各个侧板30的下端部卡合的状态固定(参照图3)。后侧Y2的连结板31架设于左右的侧板30的后端部之间，通过紧固构件32从后侧Y2固定于各个侧板30的后端部的上下方向Z上的大部区域。此外，后侧Y2的连结板31的下端部31A向前侧Y1弯曲成大致L字状，并以从下侧Z2与各个侧板30的下端部卡合的状态固定(也参照图3)。像这样通过在左右的侧板30之间架设前后的连结板31而构成的支承框架5实现了刚性的提高，因而不容易扭曲。
在一对侧板30之间，配置有洗涤桶3(参照图1)。参照用虚线来表示洗涤桶3和电机4的轮廓的图3，在洗涤桶3的外桶25的圆周壁27的左右的侧面部的从左右方向X观察同一位置处，逐一设置有向左右方向X的外侧水平突出的金属制的转动轴33。外桶25的向左侧X1突出的转动轴33贯通左侧X1的侧板30，经由轴承34由左侧X1的侧板30可转动地支承。外桶25向右侧X2突出的转动轴33(参照后述的图5)贯通右侧X2的侧板30，经由其他轴承34(参照图2)由右侧X2的侧板30可转动地支承。
像这样，左右的转动轴33通过左右的侧板30可转动地支承的洗涤桶3，由支承框架5支承，可以绕水平方向、具体地说沿左右方向X延伸的转动轴33转动。具体而言，随着洗涤桶3的转动，外桶25和脱水桶26的中心轴线J相对于上下方向Z向前后方向Y倾斜。一套洗涤桶3和电机4的构成一体转动的转动单元35。
沿上下方向Z延伸的虚拟基准轴线M与中心轴线J的锐角交叉角度为洗涤桶3相对于基准轴线M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越以外桶25的开口25A朝向前侧Y1的方式 呈向前侧Y1倾斜的姿势。转动角度θ例如能以5度、20度、25度、30度这四档进行变更。图3的转动角度θ为30度。作为洗衣机1中的应用的一个例子，在洗涤运转开始时将洗涤物投入洗涤桶3时，将转动角度θ设定为30度，使得洗涤物的投入变得容易。而且，在洗涤过程、漂洗过程中，为了促进脱水桶26内的洗涤物的位置交替，实现有效的洗涤、漂洗，将转动角度θ设定为在5度和30度之间变动。由于通过这样将转动角度θ设定在5度和30度之间，使得洗涤桶3的转动范围变得较窄，因此，能与之相应地将前后方向Y的洗衣机1的进深抑制得较小。
在左侧X1的侧板30的比转动轴33偏向下侧Z2的区域，形成有沿左右方向X贯通该侧板30的开口30A。开口30A形成为前后方向Y上尺寸长的大致长方形。在开口30A内配置有驱动机构6。驱动机构6包括：主体框架40、一对支承部41、螺纹轴42、电机43、联轴器44、螺母构件45、以及传感器46。
主体框架40通过将金属板例如折弯成曲柄状，从而以向右侧X2凹陷成凹状的方式形成，并以从右侧X2覆盖左侧X1的侧板30的开口30A的方式从右侧X2固定于该侧板30(参照从图3的A-A箭头方向观察的剖面图即图5)。一对支承部41以在前后方向Y上分离排列的状态固定于主体框架40的底部，处于从主体框架40的底部向左侧X1突出的状态。螺纹轴42形成为沿前后方向Y细长地延伸的圆柱状，在其外周面的几乎整个区域，例如形成有由梯形螺纹构成并螺旋状延伸的螺牙。螺纹轴42由设置于前后一对支承部41的轴承(未图示)可旋转地两端支承。
电机43是电动马达，其输出轴通过联轴器44可一体旋转地连结于螺纹轴42的前端部。因此，当电机43被驱动时，螺纹轴42被驱动旋转而自转。螺母构件45包括在内周面例如形成有由梯形螺纹构成并螺旋状延伸的螺牙(未图示)的环状的螺母45A、设置于螺母45A的左侧面部并向左侧X1的侧板30的开口30A的左侧X1突出的连结销45B、以及被称为限位部的杆状的被检测部45C(也参照图5)。螺母45A以其螺牙与螺纹轴42的螺牙相互螺纹配合的方式外嵌于螺纹轴42。当螺纹轴42随着电机43的驱动而旋转时，随着螺纹轴42的旋转，螺母构件45整体沿着螺纹轴42的轴向即前后方向Y移动。
传感器46是根据前后方向Y的螺母构件45的位置来检测洗涤桶3的转动角度θ的传感器，作为传感器46，能使用光传感器等光电传感器。在这种情况 下，传感器46设定为与转动角度θ的设定数相同，也就是说设定为所述的5度、20度、25度、30度这四个角度，并以沿前后方向Y排列的状态固定于主体框架40的底部。各个传感器46形成有沿前后方向Y贯通传感器46的槽46A，传感器46中，检测光处于沿上下方向Z横切槽46A的状态。与各个传感器46连接的电线47穿过各个传感器46的周围的沿左右方向X贯通主体框架40的底部的贯通孔40A，拉出到主体框架40的右侧X2。由此，即使不通过扎带来固定电线47以使其不会因振动等而偏向左侧X1，也能防止螺母构件45的被检测部45C挂到电线47。
连结部7形成为左右方向X上薄的杆状。在连结部7的长尺寸方向的一端部，形成有沿左右方向X贯通连结部7的圆形的贯通孔7A，在连结部7的长尺寸方向的另一端部，形成有沿左右方向X贯通连结部7的引导孔7B。连结部7配置于左侧X1的侧板30的左侧X1。外桶25向左侧X1突出并贯通左侧X1的侧板30的转动轴33插通连结部7的贯通孔7A，固定于连结部7。由此，连结部7经由转动轴33，与外桶25可一体转动地连结。引导孔7B为在连结部7的长尺寸方向上长的长孔，与左侧X1的侧板30的开口30A在上下方向Z上位于相同位置，始终从左侧X1与开口30A对置。
需要说明的是，固定连结部7和转动轴33时，为了防止松动，可以考虑将两个普通螺母(图示)并排安装于转动轴33，但是这样的话，洗衣机1在左右方向X上变大。因此，作为代替这两个螺母的防松螺母，例如可以各使用一个薄的轴承压紧螺母和垫片，或者只使用一个FINE U-NUT(注册商标)。在将外桶25的向右侧X2突出并贯通右侧X2的侧板30的转动轴33固定于轴承34的情况下，也能使用这些防松螺母。
此外，优选在转动轴33和连结部7的贯通孔7A的一方设置两个以上的销，并将转动轴33和连结部7销嵌合或花键嵌合。由此，由于能确保转动轴33与连结部7的连结强度，并且能使连结部7在左右方向X上较薄，因而能实现洗衣机1在左右方向X上的小型化。
螺母构件45的连结销45B以不能从右侧X2拔出的方式插入连结部7的引导孔7B，由此，螺母构件45连结于连结部7。需要说明的是，如果在将连结销45B插入引导孔7B的状态下将上述防松螺母等从左侧X1安装到连结销45B的顶端部的话，由于能在螺母构件45不绕螺纹轴42空转的稳定的状态下容易地 将螺母构件45连结于连结部7，因而能实现安装性的提高。
在螺母构件45连结于连结部7的状态下，螺纹轴42通过电机43的驱动而进行旋转，当螺母构件45沿前后方向Y移动时，连结部7通过被螺母构件45向前后方向Y拉动，从而随着洗涤桶3绕转动轴33转动。此时，对于连结部7的引导孔7B内的螺母构件45的连结销45B而言，引导孔7B的长尺寸方向上的位置改变。当电机43的驱动停止而螺纹轴42的旋转停止时，连结部7和洗涤桶3的转动停止，洗涤桶3被锁定在停止时的转动角度θ。当转动角度θ为5度、20度、25度、30度中的任意一个角度时，螺母构件45的被检测部45C嵌入四个当中的任意一个传感器46的槽46A，遮挡该槽46A的检测光。因此，四个传感器46检测转动角度θ是5度、20度、25度、30度中的哪一个。需要说明的是，如上所述由于洗涤桶3的转动范围较窄，导致伴随洗涤桶3的转动的螺母构件45的前后方向Y的行程变短，因而能与此对应地将前后方向Y的驱动机构6和支承框架5的全长缩短，将洗衣机1的进深抑制得较小。此外，由于全长变短的驱动机构6能确保强度，因而能完全承受洗涤桶3的振动。
此处，转动轴33配置为偏向中心轴线J延伸的方向上的转动单元35也就是一套洗涤桶3和电机4的中心G的下侧Z2，具体地说偏向重物即电机4侧。由此，由于转动轴33与收容洗涤物并蓄有水的状态下的转动单元35的重心相近，因而即使驱动机构6的电机43的驱动力小，也能使整个转动单元35转动。因此，能减轻为了使转动单元35转动而施加给驱动机构6的负担，并且能通过使用便宜的低扭矩的电机43来实现降成本。
承接部8存在四个，以逐一配置在俯视时的机壳2的四角的方式，逐一地固定在支承框架5的左右一对侧板30的前端部和后端部。四个承接部8当中，将位于前侧Y1的左右一对承接部8称为前侧承接部8A，将位于后侧Y2的左右一对承接部8称为后侧承接部8B。前侧承接部8A从前侧Y1安装于各侧板30的前端部的上端部，后侧承接部8B从后侧Y2安装于各侧板30的后端部的上端部。各个承接部8一体地包括：具有在前后方向Y上一致的板厚方向的基部8C、架设于基部8C的左右的端缘并向前后方向Y的外侧膨出的板状的膨出部8D、以及形成为从膨出部8D的上端向上侧Z1膨出的圆顶状的卡合部8E(也参照图2)。基部8C通过安装于支承框架5的螺钉等紧固构件48(参照图2)固定于支承框架5。
将各个承接部8中由基部8C、膨出部8D、卡合部8E围起的空间称为收容空间8F。收容空间8F是朝向卡合部8E向上侧Z1凹陷的凹部，并且从膨出部8D的下端向下侧Z2敞开。在各个承接部8，形成有沿上下方向Z贯通卡合部8E的上端部的贯通孔8G和从贯通孔8G延续并向下侧Z2延伸，将膨出部8D和卡合部8E左右对分的缝隙8H(参照图2)。贯通孔8G和缝隙8H处于与收容空间8F连通的状态。
洗涤桶3、电机4、支承框架5、驱动机构6、连结部7以及承接部8以成套状态构成组合体50。框架10的将收容空间10A向左右方向X两外侧敞开的左右一对侧面开口部10B具有供组合体50通过的大小。尤其是在将框架10的侧面开口部10B从上侧Z1区隔的各个第二上侧横支柱14，不存在上下弯曲为曲柄状的阶梯部分，因而从侧面开口部10B通过的组合体50不容易受第二上侧横支柱14干扰。因此，由于能以不分解的状态直接将组合体50从侧面开口部10B收容到收容空间10A，因而能实现安装性的提高。
支承构件9是形成为棒状的构件，又被称为吊棒，以上下尺寸长的状态配置于框架10的收容空间10A。支承构件9有四个，逐一配置于机壳2的四角(参照图2)。四个支承构件9当中，将在收容空间10A的前侧Y1的区域沿左右方向X相邻的第一对支承构件9称为前侧支承构件9A，将在收容空间10A的后侧Y2的区域沿左右方向X相邻的第二对支承构件9称为后侧支承构件9B。一对前侧支承构件9A的排列方向为左右方向X，相对于该排列方向的正交方向为前后方向Y。一对后侧支承构件9B位于前后方向Y中向后侧Y2远离一对前侧支承构件9A的位置。左右一对前侧支承构件9A位于从左右方向X观察时重叠的位置，左右一对后侧支承构件9B位于从左右方向X观察时重叠的位置。
作为各个支承构件9的一个例子，可以举出摩擦阻尼器。当然，支承构件9能使用液压阻尼器等其他的公知阻尼器。摩擦阻尼器的情况下的支承构件9包括往上下细长地直线状延伸的杆52和收容杆52的下端部的中空的壳体53。参照支承构件9的主要部分及其周边部分的示意性的纵剖图即图4，支承构件9包括在壳体53内连结于杆52的下端部的圆盘状的阻尼器构件54和配置于壳体53内的螺旋弹簧等施力构件55。杆52相对于壳体53可相对移动，通过该相对移动，支承构件9整体可伸缩。此外，由于在壳体53内施力构件55对阻尼器构件54向下侧Z2施力，因而支承构件9整体可弹性伸缩。
壳体53形成为上下尺寸长的大致圆筒状。壳体53的上端部作为下侧卡合部53A，形成为向上侧Z1膨出的半球状。杆52处于上下贯通下侧卡合部53A的上端53B并向上侧Z1突出的状态。各个前侧支承构件9A的下侧卡合部53A从下侧Z2嵌入在左右方向X上位于相同位置的前侧承接部8A的收容空间8F，由此，处于从下侧Z2与该前侧承接部8A的卡合部8E卡合的状态。各个后侧支承构件9B的下侧卡合部53A从下侧Z2嵌入在左右方向X上位于相同位置的后侧承接部8B的收容空间8F，由此，处于从下侧Z2与该后侧承接部8B的卡合部8E卡合的状态。
这样，支承洗涤桶3的支承框架5的四个承接部8逐一安装于位于各个支承构件9的下端部的下侧卡合部53A。各个支承构件9的下端部处于经由承接部8和支承框架5连结于洗涤桶3的状态(参照图1)。需要说明的是，在将下侧卡合部53A嵌入收容空间8F时，杆52穿过承接部8的缝隙8H(参照图2)。在各支承构件9，下侧卡合部53A处于与卡合部8E的划分出收容空间8F的内周面8I球面接触的状态，杆52处于从承接部8的上端部的贯通孔8G向上侧Z1突出的状态。
参照图1，在各个支承构件9的杆52的上端部，设置有大致圆筒状的上侧卡合部52A。各个前侧支承构件9A的上侧卡合部52A从上侧Z1嵌入框架10的在左右方向X上位于同一位置的第二上侧横支柱14的前侧连结部18A的贯通孔18C，由此，处于从上侧Z1与前侧连结部18A卡合的状态。各个后侧支承构件9B的上侧卡合部52A从上侧Z1嵌入在左右方向X上位于同一位置的第二上侧横支柱14的后侧连结部18B的贯通孔18C，由此，处于从上侧Z1与后侧连结部18B卡合的状态。参照图5，各个上侧卡合部52A的外周面的至少一部分具有曲面部分，各个上侧卡合部52A在该曲面部分处于与连结部18的贯通孔18C的内周面18D球面接触的状态。
如上所述，在洗涤桶3侧的承接部8连结有下端部并在框架10侧的连结部18连结有上端部的各个支承构件9处于从框架10的第二上侧横支柱14的各个连结部18悬吊的状态(参照图1)。由于各个支承构件9可弹性伸缩，因而四个支承构件9处于将洗涤桶3、电机4、支承框架5、驱动机构6、以及连结部7悬吊并弹性支承的状态(参照图1)。因此，抑制在洗涤运转中、特别是脱水过程中随着脱水桶26的旋转而在洗涤桶3产生的振动经由连结部18传到机壳2。
此外，由于在各个支承构件9中，阻尼器构件54在支承构件9伸缩时与杆52的下端部一起移动，并在此时与壳体53的内周面53C(参照图4)滑动摩擦，因而在阻尼器构件54与内周面53C之间产生摩擦力。洗涤桶3中产生的振动通过该摩擦力被减弱。由于各个支承构件9如上所述处于上侧卡合部52A与连结部18球面接触而下侧卡合部53A与承接部8的卡合部8E球面接触的状态，因而各个支承构件9能自由改变相对于上下方向Z的倾斜，以使因洗涤桶3的振动而产生的强制力不会作用在支承构件9自身、机壳2上。
支承框架5的四个承接部8都配置于同一高度位置，特别是，四个承接部8的各个贯通孔8G在上下方向Z上位于同一位置(参照图2)。因此，四个支承构件9的从下侧Z2嵌入承接部8的收容空间8F的壳体53在上下方向Z上配置于相同位置。具体地说，四个支承构件9的壳体53的下侧卡合部53A的从贯通孔8G露出的上端53B(参照图4)在上下方向Z上配置于相同位置。
另一方面，在机壳2的框架10的左右的第二上侧横支柱14前低后高地倾斜的结构上，左右的第二上侧横支柱14的四个连结部18当中，一对前侧连结部18A位于比一对后侧连结部18B低的位置(参照图2以及图3)。这种情况下，在四个支承构件9中，具有与前侧连结部18A卡合的上侧卡合部52A的一对前侧支承构件9A彼此长度相同，具有与后侧连结部18B卡合的上侧卡合部52A的另一对后侧支承构件9B彼此长度相同。但是，前侧支承构件9A比后侧支承构件9B短(参照图2)。需要说明的是，此处的支承构件9的长度在一个例子中是指在洗衣机1的运转停止的状态下，将上侧卡合部52A的与连结部18的下表面一致的部分9C和下侧卡合部53A的上端53B连结并沿着杆52延伸的线段L的长度(参照图4以及图5)。线段L的长度是各个支承构件9的从承接部8到连结部18的范围的部分，也就是支承构件9的有助于主动减弱振动的部分的长度。当然，作为其他的例子，也可以将杆52的全长、支承构件9的全长定义为支承构件9的长度。
各个支承构件9的上端为支承构件9的构成线段L的部分的上端，在本实施方式中，为杆52的上侧卡合部52A。参照从图3的B-B箭头方向观察到的剖面图即图6，一对前侧支承构件9A的上端彼此的左右方向X的间隔D1比一对后侧支承构件9B的上端彼此的左右方向X的间隔D2大。间隔D1是一对前侧支承构件9A向机壳2的框架10安装的安装宽度，间隔D2是一对后侧支承构 件9B向机壳2的框架10安装的安装宽度。需要说明的是，可以将间隔D1看作是左右一对前侧连结部18A的贯通孔18C彼此的间隔，也可以看作是这些贯通孔18C的中心间的距离。同样，可以将间隔D2看作是左右一对后侧连结部18B的贯通孔18C彼此的间隔，也可以看作是这些贯通孔18C的中心间的距离。
此外，以洗衣机1的运转停止的状态为基准，一对前侧支承构件9A以相互的左右间隔越向下侧Z2越窄的方式相对于上下方向Z倾斜，一对后侧支承构件9B以相互的左右间隔越向下侧Z2越宽的方式相对于上下方向Z倾斜。因此，从前后方向Y观察，一对前侧支承构件9A配置为V字状，与此相对，一对后侧支承构件9B配置为上下颠倒的V字状。需要说明的是，从左右方向X观察，前侧支承构件9A和后侧支承构件9B各自可以沿上下方向Z配置，也可以相对于上下方向Z倾斜地配置。
通过利用这样由一对前侧支承构件9A和一对后侧支承构件9B构成的不同的四个支承构件9来弹性支承洗涤桶3，参照图1，因脱水桶26的旋转而产生的洗涤桶3的振动减弱，因振动而产生的洗涤桶3的摆幅变小。由此，能抑制振动中的洗涤桶3与机壳2接触。因此，能实现因洗涤桶3与机壳2接触而产生的噪音的减弱。此外，由于洗涤桶3的摆幅小，因而能不改变洗涤桶3的大小而是通过缩小机壳2来缩小洗涤桶3与机壳2的间隔。由此，能以不减小洗涤桶3的洗涤物的容量的方式实现洗衣机1的小型化。此外，通过减弱振动，能减轻对转动洗涤桶3的驱动机构6的负担。
此外，连结有各个支承构件9的下端部的承接部8固定于支承框架5的各个侧板30的前端部和后端部各自的上端部，由此，所有四个支承构件9被设定为尽可能短。由此，因振动而产生的洗涤桶3的摆幅进一步变小，因而能进一步缩小洗涤桶3与机壳2的间隔，能实现洗衣机1的进一步小型化。
此外，由于支承框架5通过连结板31实现了刚性的提高，因而，因洗涤桶3的振动而产生的支承框架5的扭曲减轻。由此，支承框架5与机壳2接触的情况被抑制，能通过缩小支承框架5与机壳2的间隔来实现洗衣机1的小型化。
此外，在机壳2的框架10中，前侧Y1的第一上侧横支柱13架设于两个第二上侧横支柱14的前端之间。由此，该第一上侧横支柱13配置为在各个第二上侧横支柱14的前端部与连结于前侧支承构件9A的上端部的前侧连结部18A贴近。进而，该第一上侧横支柱13不作为独立部件通过螺钉等附加于框架10， 而是通过焊接等与框架10一体化。因此，框架10的容易传递洗涤桶3的振动的前侧连结部18A的周边的刚性提高。由此，因洗涤桶3的振动而产生的框架10的摆幅变小，因而能缩小机壳2的框架10与装饰盖11的间隔，能实现洗衣机1的进一步小型化。
此外，一对前侧支承构件9A配置于一对后侧支承构件9B的前侧Y1。由此，通过在上端彼此的间隔相对较窄的一对后侧支承构件9B所在的洗衣机1的后部1A的周缘部，也就是机壳2的后侧Y2的角落部分C实施倒角加工等，能在左右方向X上缩小后部1A的宽度。因此，由于能实现洗衣机1的进一步小型化，因而能实现洗衣机1的设置空间的减小。
此外，框架10的位于机壳2的前表面部2A且越向上侧Z1越往前侧Y1弯曲的前侧纵支柱12A具有弹性。因此，能通过前侧纵支柱12A的弹性变形吸收经由支承构件9传给框架10的洗涤桶3的振动。由此，能抑制因脱水桶26的旋转而产生的洗涤桶3的振动传到安置面，进一步减弱振动和噪音。
本发明并不局限于以上所说明的实施方式，可以在权利要所记载的范围内进行各种变更。
例如，在上述的洗衣机1中，能通过洗涤桶3绕转动轴33转动来改变姿势。取而代之，也可以省略使洗涤桶3转动的结构而在外桶25设置承接部8，并由各个支承构件9来直接弹性支承洗涤桶3，由此在转动角度θ恒定在0度或几度的状态下，始终竖直放置地配置洗涤桶3。无论是哪种洗衣机1，都如上所述能以不减小洗涤物的容量的方式实现小型化，实现振动和噪音的减弱。
此外，也可以是将上述的洗衣机1的前侧Y1和后侧Y2颠倒的结构，也就是一对前侧支承构件9A和一对后侧支承构件9B前后位置颠倒的结构。
