Description

洗衣机 技术领域
本发明涉及具有脱水功能的洗衣机。
背景技术
设置于普通家庭或者投币式洗衣房等处的洗衣机有的具备洗涤脱水功能、洗涤脱水烘干功能。
具有脱水功能的洗衣机由于洗涤物在旋转滚筒内的偏倚而产生振动、噪声。此外只要洗涤物的偏倚大，旋转时的旋转滚筒的偏心就大，由于旋转需要大的转矩，因此无法开始脱水运转。为了消除这个问题，使用者停止洗衣机的运转并通过手动操作消除洗涤物的偏倚。
为了消除这种繁琐的操作，提出了一种洗衣机，其在判断出作为洗涤物的偏倚的不平衡的大小比规定值大的情况下，使旋转滚筒减速到离心力根据位置检测单元的输出定时，达到比重力小的旋转速度为止，以消除洗涤物的跑偏(参照专利文献1)。
此外，还提出一种洗衣机，其通过对旋转滚筒的前部以及后部配设的加速度传感器，计算出检测到的振动量之差，以检测洗涤物向旋转滚筒的前部偏倚的不平衡状态，由此防止产生脱水时洗涤物向旋转滚筒的前部偏倚的不平衡(专利文献2)。
现有技术文献

专利文献2：日本特开2009-82558号公报
发明内容
上述专利文献1中公开的技术为通过使旋转滚筒的旋转减速而使离心力递减，以使重叠的洗涤物通过重力落下来的技术。然而，由于在该现有技术中相互缠绕成一团的洗涤物会直接落下来，因而不能打散这一团洗涤物。当旋转滚筒在这样的状态下进行旋转时，由于未消除不平衡，因而会再次检测出不平衡， 会反复进行旋转滚筒的减速。
另一方面，上述专利文献2中公开的技术为在旋转滚筒旋转时，计算通过前部的振动检测单元检测到的振动值和通过后部的检测单元检测到的振动值之差。然后，在该振动值之差大于预先设定的阈值的情况下，使旋转滚筒的旋转减速或停止的技术。
然而，即使通过该现有技术，相互缠绕成一团的洗涤物也依然不能解开，残存在旋转滚筒内，不能成为消除不平衡的根本的解决方案。
进一步地，根据上述专利文献1、2，由于使旋转滚筒的旋转减速或停止，因而每次重复进行脱水运转都需要起动电力，存在增加耗电的问题。
本发明为解决该现有问题的技术。根据本发明，能够提供一种洗衣机，即使在旋转滚筒内存在洗涤物的跑偏，也能够在脱水运转时可靠地消除旋转滚筒的不平衡，减少旋转滚筒的偏心所导致的振动的产生、噪声的产生，高效地进行洗涤物的脱水。
本发明为一种洗衣机，具备：多个中空的平衡器6，沿着旋转滚筒5的轴线S1方向等间隔地配设在该旋转滚筒5的内周面上；接水环单元18，制成环状并对应所述平衡器6的数量以层叠状态构成使内周面打开、外周面由底板21闭塞的导水筒19a、19b、19c，并且该接水环单元固定于所述旋转滚筒5的背面；疏水构件24a、24b、24c，将所述导水筒19a、19b、19c的底板21的一部分和所述平衡器6之间连接起来；以及喷嘴单元25，独立地向所述导水筒19a、19b、19c注入调整水。
此外本发明的特征在于，所述接水环单元18的各层导水筒19a、19b、19c的底板21相对于旋转滚筒5的轴线S1偏心，并且以使相邻的导水筒19a、19b、19c的偏心方向的角度差相同的方式进行固定，在该导水筒19a、19b、19c的偏心顶部具备所述疏水构件24a、24b、24c。
此外本发明的特征在于，所述平衡器6为抬起洗涤物的提升筋。
此外本发明的特征在于，在所述提升筋的内部配设有位于该提升筋的主体开口部一侧的从前端朝向后端的下倾斜的倾斜板6c。
此外本发明的特征在于，在疏水构件24a、24b、24c向所述导水筒19a、19b、19c的底板21的安装位置上，所述底板21成为漏斗状。
根据本发明，洗衣机由于注入与旋转滚筒一体地旋转的接水环单元的选定的导水筒中的调整水经由疏水构件供应给平衡器，消除因洗涤物的偏倚而产生 的不平衡，因而能在保持继续进行通常的脱水运转的状态下防止振动、噪声的产生。
由于本发明的洗衣机使接水环单元的各层导水筒的底板相对于旋转滚筒的轴线偏心，因而在接水环单元进行旋转时产生朝向偏心顶部方向的离心力，能将注入到所述导水筒中的调整水高效地供应给平衡器。
由于本发明的洗衣机以平衡器作为提升筋，因而能获得旋转滚筒的平衡调整和抬起洗涤物的两项功能。
由于本发明的洗衣机在提升筋的内部配设有从前端朝向后端的倾斜板，因而能高效地排出调整水。
由于本发明的洗衣机使接水环单元的导水筒的底板的疏水构件的安装部分形成为漏斗状，因而促进了注入导水筒中的调整水的滞留，能将调整水高效地供应给平衡器。

具体实施方式
以下，基于附图详细说明本发明的实施方式。图1为表示本发明的一个实施方式的洗衣机1的外观的主视图。图2为表示洗衣机l的内部结构的示意图。图3为旋转滚筒5的正面立体图。图4为旋转滚筒5的背面立体图。图5为旋转滚筒5的侧视图。
如图2所示，洗衣机1是构成为包括主体2、内包于主体2的外槽3、安装于主体上的门体4、以及内包于外槽3的旋转滚筒5的水平滚筒式的洗衣机。在主体2的前表面形成有用于投入取出洗涤物的开口部2a。在开口部2a上开闭自由地设置有将该开口部维持关闭状态以及打开状态的门体4。
外槽3形成为大致有底圆筒状。具体地说，外槽3构成为包括：圆盘状的底部3b、与底部3b的外缘部相连的圆筒状的侧壁部3c、与侧壁部3c相连的圆环状的节流部3d、以及与节流部3d相连并形成有与主体2的开口部2a对置的开口部3a的圆筒状的开口壁部。外槽3具有向大致水平方向延伸的轴线S1。外槽3配置为其开口部与主体2的开口部对置。
在外槽3的内部空间中配置有旋转滚筒5。旋转滚筒5形成为大致有底圆筒状。具体地说，旋转滚筒5构成为包括：圆盘状的底部、与底部的外缘部相连的圆筒状的侧壁部、与侧壁部相连的圆环状的节流部、以及与节流部相连并且形成有开口部5a的圆筒状的开口壁部。旋转滚筒5的轴心与外槽3的轴线一致。在旋转滚筒5的侧壁部形成有贯穿厚度方向的多个通孔5b。
门体4开闭自由地设置于形成在主体2的前表面的开口部处。如图2所示，门体4为通过关闭主体2的开口部2a，从而使门体4的背面的凸部4a进入外槽3的开口部3a和旋转滚筒5的开口部5a，防止旋转滚筒5内的洗涤物的飞出的结构。
图6是配设于旋转滚筒5中的提升筋6的立体图。
在旋转滚筒5内设置有与轴线S1方向并列延伸的多个(在本实施方式中为三个)提升筋6。在本发明中，提升筋6也作为平衡器发挥功能。在这种情况下，提升筋6形成为从旋转滚筒5的周壁朝着轴线S1突出成三角形状的中空体，在进行旋转滚筒5的旋转驱动时抬起洗涤物。提升筋6空出等间隔地设置在旋转滚筒5的圆周方向上。在本实施方式中，提升筋6如图3所示空出120°的间隔地设置在旋转滚筒5的圆周方向上。
洗衣机1还包括驱动部和接水环单元18。驱动部构成为包括：固定于外槽3的底部3b处的轴承7、主轴8、带轮9、滚筒电机10、以及传动带11。轴承7设置于旋转滚筒5的底部的中央处。主轴8的一端部固定于旋转滚筒5的底部，另一端部固定于带轮9上。轴承7以可旋转的方式对主轴8进行轴支承。主轴8的轴心与所述轴线S1一致。
滚筒电机10具有输出轴10a。传动带11架设于带轮9和输出轴10a之间。滚筒电机10的转矩通过传动带传递给带轮9、主轴8，旋转滚筒5由此进行旋转。
图7(A)为配设于旋转滚筒5中的提升筋6的剖视图，图7(B)为配设于旋转滚筒5中的提升筋6的侧视图。图8(A)为表示配设于旋转滚筒5中的提升筋6的其他例子的剖视图，图8(B)为表示配设于旋转滚筒5中的提升筋6的其他例子的侧视图。
提升筋6具有后述的供应调整水的疏水构件24a、24b、24c中的任一个所连接的管杆6a、以及用于排出滞留在提升筋6内的调整水的管杆6b。通过这样构成提升筋6，从而能够进行提升筋6的安装位置的调整水所引起的重量的改变，能够获得作为平衡器(balancer)的功能。此外，如图8所示通过在提升筋6内设置从前端朝向后端下倾斜的倾斜板6c，能促进调整水的排出。此外，在不具备提升筋的机种中，也可以与上述的结构相同地沿着轴线S1方向在旋转滚筒5的内周面上设置长条的中空体。此外，所述管杆6b设置于提升筋6的后部即顶部侧。由此，能够将滞留于提升筋6内的调整水排到旋转滚筒5外部。
在所述外槽3的与旋转滚筒5的顶端部分对应的位置，配设有检测水平和垂直两个方向的加速度的加速度传感器12。另一方面，配设有检测设置于所述带轮9上的传感器标记13的接近开关14。此外，用于将滞留的脱水液W排到主体2外的排水管15与外槽连接，设成能够通过电磁阀16的开闭将脱水液W 排到主体2外。
接着，就用于供应调整水给提升筋6的接水环单元18的结构进行说明。图9为配设于旋转滚筒5中的接水环单元18的剖视图。图10为接水环单元18的其他结构例的说明图。图11为图9的接水环单元18的组装立体图。图12为图10的接水环单元18的组装立体图。图13为图9的接水环单元18的结构的说明图。图14为图9的接水环单元18的组装状态的说明图。图15为接水环单元18的其他结构例的说明图。
接水环单元18如图4、图5所示固定于旋转滚筒5的背面。接水环单元18构成为制成环状并使内周面打开、外周面由底板21闭塞的三层导水筒19a、19b、19c在旋转滚筒5的轴线S1方向上层叠。
接水环单元18的第一个例子如图9、图11所示制成将板材进行组装。该接水环单元18以在相同形状的圆形的环形板20之间夹持了相同形状的圆形的底板21的状态进行一体化。由此，形成以底板21作为底面并以环形板20作为侧壁的三层导水筒19a、19b、19c。在这种情况下，如在图13中将各底板21的位置用点划线、单点划线、双点划线所示，使底板21离环形板20的中心RC偏心距离(d)，该位置成为偏心中心EC。
环形板20和底板21的组装如在图14中用点划线、单点划线、双点划线所示，使相邻的底板21的偏心方向的角度差为120°。然后，将与疏水构件24a、24b、24c连接的管杆22a、22b、22c固定在位于环形板20的外侧端部的底板21的偏心顶部。这样构成的接水环单元18固定为使环形板20的中心RC与旋转滚筒5的轴线S1一致。由此，各导水筒19a、19b、19c的各底板21配置为以旋转滚筒5的轴线S1为中心具有120°的角度差地进行偏心。
如上那样构成的接水环单元18的管杆22a、22b、22c，如图4所示与疏水构件24a、24b、24c的一端连接，其另一端与提升筋6的管杆6a连接。此外，使疏水构件24a、24b、24c的向提升筋6的安装位置为提升筋6的底部侧。由此，能促进供应给提升筋6的调整水向偏心方向的滞留。
通过这样的构成，在通过后述的方式向导水筒19a、19b、19c的内部注入调整水的情况下，当接水环单元18的旋转大于产生离心力的临界旋转速度时，注入导水筒19a、19b、19c内的调整水受到朝向偏心方向的负荷并朝着管杆22a、22b、22c往下流。此外，将管杆22a、22b、22c的安装部如图15所示，通过将底板21形成为漏斗状，能促进调整水的滞留。
在图10、图12中示出接水环单元18的第二个例子。该第二个例子中，将与第一个例子中的环形板20和底板21相当的结构一体成型为剖面“コ”字型的圆形的导水环23形成一个导水筒。通过这样成型的导水环23的层叠来形成导水筒19a、19b、19c，构成接水环单元18。由于这样构成的导水环23为相同形状，因而与第一个例子相同地以旋转滚筒5的轴线为中心使导水筒19a、19b、19c配置成以相互120°的角度差进行偏心，由偏心顶部将管杆22a、22b、22c固定于底板21。通过这样构成接水环单元18，从而能自由地设定偏心量，偏心的范围不会像第一个例子那样受环形板20的宽度限制。
在上述接水环单元18的结构的第一、第二个例子的情况下，配设三个导水筒19a、19b、19c和与此相应地成为平衡器的三个提升筋6。而且使以旋转滚筒5的轴线为中心的导水筒19a、19b、19c的底板21的各偏心顶部相互之间的角度和提升筋6的相互之间的角度都为120°。此外，虽然导水筒19a、19b、19c的底板21选为作为本实施例的优选方式的圆形，但是只要能获得与此相同的功能，也可以选为包括椭圆的椭圆形、或者多角形。
注入如以上那样构成的接水环单元18的导水筒19a、19b、19c内的调整水通过离心力朝着偏心顶部流动，从管杆22a、22b、22c经由疏水构件24a、24b、24c供应给各提升筋6内。被供应的调整水在提升筋6内滞留在偏心方向的壁面上。通过像这样供应调整水给提升筋6，能增加该提升筋6的重量。因此，只要以打散洗涤物团的方式供应调整水给提升筋6内，就能消除旋转滚筒5的不平衡。由此，由于能提高旋转滚筒5的转速，因而能开始脱水运转。
随着结束脱水运转并降低旋转滚筒5的旋转速度，提升筋6内的离心力也逐渐衰减变得不受其影响，调整水在提升筋6内游动，通过重力从管杆6b排出。此时，通过将如图8所示的倾斜板6c设置在提升筋6的内部，从而尤其是水平滚筒中能进行高效的排水，不会在提升筋6内残存调整水。
接着，关于用于注入调整水给导水筒19a、19b、19c的喷嘴单元25进行说明。该喷嘴单元25如图16所示具备朝向导水筒19a、19b、19c的底板21配置的三个喷嘴25a、25b、25c。喷嘴25a、25b、25c朝向接水环单元18的旋转方向倾斜地设置。由此，在从各喷嘴25a、25b、25c喷射出调整水时，由于该调整水沿着导水筒19a、19b、19c的底板21的曲面注入因而不会在导水筒19a、19b、19c内飞散，能顺利地注水。
所述调整水在图2所示系统的情况下，经由电磁阀26a、26b、26c将自来水 供应给喷嘴25a、25b、25c，在后述的图21所示系统的情况下通过泵17压送的脱水液W经由电磁阀26a、26b、26c供应给喷嘴25a、25b、25c。此外，所述电磁阀26a、26b、26c也可以采用换向电磁阀。
接着，关于用于进行本发明的洗衣机1的运转控制的图17所示的电气系框图进行说明。在控制部30中具备执行系统整体的控制的中央控制部(CPU)31。该控制部31与存储器32连接，该存储器32存储旋转滚筒5的旋转控制所需的脱水运转开始前的低速旋转设定值(N1)、脱水运转开始后的高速旋转设定值(N2)、低速脱水运转时的不平衡量设定值(m1)、以及高速脱水运转时的不平衡量设定值(m2)。
中央控制部31输出控制信号给旋转速度控制部33，还将该控制信号输出给电机控制电路34来进行滚筒电机10的旋转控制。此外，旋转速度控制部33实时从电机控制部34输入表示滚筒电机10的旋转速度的信号，并将其设为控制要素。不平衡量检测部35以及不平衡位置检测部36与加速度传感器12连接，并且所述不平衡位置检测部36与接近开关14连接。
由此，当接近开关14检测到传感器标记13时，根据加速度传感器12发出的水平方向和垂直方向的加速度的大小，在不平衡量检测部35中计算出不平衡量(M)，并将该不平衡量输出给不平衡量判断部37。另一方面，不平衡位置检测部36根据从接近开关14输入的表示传感器标记13的位置的信号，计算出不平衡方向的角度，并将不平衡位置信号输出给注水控制部38。
当所述注水控制部38输入来自不平衡量判断部37以及不平衡位置检测部36的表示不平衡量和不平衡位置的信号时，基于预先储存的控制程序判断向旋转滚筒5内的哪一个提升筋6进行供水以及其供水量。然后打开选定的电磁阀26a、26b、26c，开始注入调整水。当在旋转滚筒5中产生不平衡时，开始从基于该不平衡量的计算而选定的喷嘴25a、25b、25c对接水环单元18的导水筒19a、19b、19c进行调整水的注入，当通过提升筋6消除了不平衡时，停止注入调整水。由此，不使旋转滚筒5的旋转减速，就能在继续进行脱水运转的状态下防止振动、噪声的产生。
此外，所述注水控制部38中的提升筋6的决定例如图18所示，在成为不平衡的要素的洗涤物团LD处于旋转滚筒5的位置B和位置C的提升筋6之间的情况下，供应调整水给位置A的提升筋。此外，如图19所示在洗涤物团LD处于位置A的提升筋6的附近的情况下，供应调整水给处于位置B和位置C的 提升筋6。
接着，以下基于图20所示的流程图对本发明的洗衣机1的脱水运转的控制流程进行说明。
(步骤S1)
在步骤S1中，当中央控制部31接收到来自未图示的脱水按钮的输入信号或者在洗涤程序运转中接收到表示应该开始脱水过程含义的信号时，开始脱水过程，并移至步骤2。
(步骤S2)
在步骤S2中，中央控制部31通知表示开始低速旋转(N1)含义的信号给旋转速度控制部33。旋转速度控制部33基于所述通知发出控制信号给电机控制部34，电机控制部34基于该控制信号流通电流，驱动滚筒电机10。由此，旋转滚筒5以预定的转速(在本实施方式中为100rpm～400rpm)进行旋转驱动，并移至步骤S3。
(步骤S3)
在步骤S3中，中央控制部31访问不平衡位置检测部36，并判断不平衡位置检测部36是否接收到了接近开关14发出的表示检测到了传感器标记13的信号。只要检测到了传感器标记13就移至步骤S4，只要没有检测到传感器标记13就重复步骤S3。
(步骤S4)
在步骤S4中，中央控制部31访问不平衡量检测部35，取得加速度传感器12给出的水平方向和垂直方向的加速度，并进行预定的运算，计算出不平衡量M，并且通过不平衡位置检测部36检测不平衡位置，移至步骤S5。
(步骤S5)
在步骤S5中，中央控制部31将不平衡量M与储存于存储器32的不平衡量设定值(m1)进行对比，判断M>m1是否成立。在M>m1成立的情况下移至步骤S6，在M>m1不成立的情况下移至步骤S7。不平衡量设定值(m1)为能开始旋转滚筒5的高速旋转的预定的不平衡量的阈值。在步骤S5中，M>m1不成立是指不平衡量M为能开始旋转滚筒5的高速旋转的值。换言之，M>m1不成立是指旋转滚筒5的不平衡得到了改善，或者从最初就不存在。
(步骤S6)
在步骤S6中，中央控制部31发送开始注水的信号给注水控制部38，开始 进行对提升筋6的调整水的注入。此外在步骤6的动作为第二次循环的情况下，继续进行在最初的步骤6中打开的电磁阀26a～26c的打开。
具体地说，中央控制部31在不平衡位置的检测结果为洗涤物团LD如图18所示存在于提升筋6之间的情况下，打开与处于与洗涤物团LD对置的位置的提升筋6对应的电磁阀26a～26c中的任一个，并开始对处于与洗涤物团LD对置的位置的提升筋6注水。
此外中央控制部31在不平衡位置的检测结果为洗涤物团LD如图19所示存在于任一个提升筋6的附近的情况下，打开与该提升筋6之外的提升筋6对应的电磁阀26a～26c，并开始对处于洗涤物团LD附近的提升筋6之外的提升筋6注水。然后，返回步骤S3。
(步骤S7)
在步骤S7中，中央控制部通知表示应该关闭电磁阀26a～26c含义的指令给注水控制部38，停止供应调整水给提升筋6。然后移至步骤S8。
(步骤S8)
在步骤S8中，中央控制部31开始进行旋转滚筒5的高速旋转。具体地说，中央控制部31通知表示应该开始进行高速旋转含义的信号给旋转速度控制部33。旋转速度控制部33基于所述通知发送控制信号给电机控制部34，电机控制部34基于该控制信号流通电流，驱动滚筒电机10。由此，使旋转滚筒5以成为预先设定的高速的转速(在本实施方式中为500rpm～800rpm)的方式进行旋转驱动，并移至步骤S9。
(步骤S9)
在步骤S9中，中央控制部31访问不平衡位置检测部36，判断接近开关14是否检测到了传感器标记13。在判断出接近开关14检测到了传感器标记13的情况下移至步骤S10，在判断出接近开关14没有检测到传感器标记13的情况下重复步骤S9。
(步骤S10)
在步骤S10中，中央控制部31访问不平衡量检测部35，取得加速度传感器12给出的水平方向和垂直方向的加速度，并进行预定的运算，算出不平衡量M，并且通过不平衡位置检测部36检测不平衡位置，移至步骤S11。
(步骤S11)
在步骤S11中，中央控制部31将不平衡量M与储存于存储器32的不平衡 量设定值(m2)进行对比，判断M>m2是否成立。在M>m2成立的情况下移至步骤S12，在M>m2不成立的情况下移至步骤S11。
不平衡量设定值(m2)为即使将旋转滚筒5的转速提高到预定的高速的转速也不会产生问题的、预定的不平衡量的阈值。在步骤S11中，M>m2不成立是指不平衡量M为能高速旋转旋转滚筒5的值。换言之，M>m2不成立是指旋转滚筒5的不平衡被改善成能进行高速旋转的程度、或者不存在从最初开始妨碍高速旋转程度的不平衡。
(步骤S12)
在步骤S12中，中央控制部31发送开始注水的信号给注水控制部38，开始进行对提升筋6的调整水的注入。此外在步骤12的动作为第二次循环的情况下，继续进行在最初的步骤6中打开的电磁阀26a～26c的打开。
具体地说，中央控制部31在步骤S10中的不平衡位置的检测结果为洗涤物团LD如图18所示存在于提升筋6之间的情况下，打开与处于与洗涤物团LD对置的位置的提升筋6对应的电磁阀26a～26c中的任一个，并开始对处于与洗涤物团LD对置的位置的提升筋6注水。
此外中央控制部31在步骤S10中的不平衡位置的检测结果为洗涤物团LD如图19所示存在于任一个提升筋6的附近的情况下，打开与该提升筋6之外的提升筋6对应的电磁阀26a～26c，并开始对位于洗涤物团LD的附近的提升筋6之外的提升筋6注水。然后返回步骤S9。
(步骤S13)
在步骤S13中，中央控制部31通知表示应该关闭电磁阀26a～26c含义的指令给注水控制部38，停止供应调整水给提升筋6。然后移至步骤S14。
(步骤S14)
在步骤S14中，中央控制部13访问未图示的计时部，判断旋转滚筒5达到预定的高速转速的之后的经过时间是否大于预定的脱水运转的设定时间。只要经过时间大于脱水运转的设定时间就移至步骤S15，只要经过时间没有大于脱水运转的设定时间就返回步骤S9。
(步骤S15)
在步骤S15中，通知表示应该结束脱水运转含义的信号给旋转速度控制部，使滚筒电机10的旋转驱动停止。如此结束脱水运转。
在如此结束脱水运转的过程中，伴随着缓慢的旋转直到旋转滚筒5的旋转 停止，被供应的提升筋6内的调整水能全部排出到外部并返回到初始状态，能重复进行正确的控制。
根据上述的脱水运转的流程，能够提供一种洗衣机，由于在低速旋转时和高速旋转时这两个阶段下检测旋转滚筒5的不平衡状态，并消除不平衡状态，因而在从脱水运转开始到结束的任何过程中都能防止振动、噪声的产生。
图21表示本发明的其他实施方式，由于可以将排水管15分路成支管16并通过泵17回收滞留在外槽3的底部的脱水液，作为调整水重复使用，因此提高了经济性。
此外，在上述实施例中接水环单元18由三个导水筒19a、19b、19c构成，与此对应设置了三个平衡器6，但是本发明并不局限于此，包括如下的接水环单元18的结构：当平衡器6为两个以上的多个时，接水环单元18具备与该数量对应的导水筒。
如上述详细的说明，根据本发明的洗衣机，通过由与旋转滚筒一起旋转的接水环单元所产生的离心力，能供应调整水给提升筋并消除旋转滚筒的不平衡。由于该接水环单元所产生的离心力与旋转滚筒的配置状态无关，因此本发明的实施不局限于本实施方式的水平滚筒式，也可以是纵型滚筒式、倾斜滚筒式的洗衣机。
