具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的技术特征可以相互组合，具体实施方式中的详细描述应理解为本申请宗旨 的解释说明，不应视为对本申请的不当限制。
本申请实施例提供一种衣物处理设备，请参阅图19，衣物处理设备包括外筒21、内筒20以及转动平衡装置10(参照图1)，内筒20转动地设置于外筒21内，内筒20具有转动轴线，转动平衡装置10具有转动中心线，内筒20与转动平衡装置10同步转动，转动平衡装置10用于在内筒20转动过程中出现负载偏心情况下对内筒20进行平衡调节。
衣物处理设备可以是烘干机、脱水机、洗衣机中的任一种或多种的集成。其中，转动平衡装置10的转动中心线与与内筒20的转动轴线平行或重合，也就是说，转动平衡装置10可以与内筒20同轴设置，也可以略微偏心设置，在此不做限制。转动平衡装置10的转动中心线可以是沿竖直方向，例如，转动平衡装置10适用于波轮洗衣机的情况；也可以是水平方向，例如，转动平衡装置10适用于滚筒洗衣机的情况；还可以是倾斜方向。在此不做限制。
请参阅图1和图2，转动平衡装置10包括转动本体11以及间隔壁12，转动平衡装置10的转动中心线即为转动本体11的转动中心线，转动本体11绕该转动中心线转动。转动本体11内形成有沿周向分布的多个腔室11a，多个腔室11a的内部空间相互隔离以阻隔液体在多个腔室11a之间流通，如此便于根据内筒20的负载偏心程度和偏心位置单独地控制各个腔室11a的注液量；其中，至少一个腔室11a内设置有间隔壁12，间隔壁12沿转动本体11的周向延伸以将腔室11a沿径向间隔出多个连通的流道101，液体可以在多个流道101之间流动，间隔壁12的内壁面12b朝向转动本体11的转动中心线，也就是说，被间隔壁12间隔出的相邻两个流道101中，其中一个流道101位于间隔壁12的沿转动本体11的径向的内侧，其中另一个流道101位于间隔壁12的沿转动本体11的径向的外侧。
本申请的转动平衡装置10，在对应的腔室11a中注入液体后，在转动 平衡装置10转动过程中，请参阅图7，一方面，液体在离心力的作用下会被甩向腔室11a的最外侧的内壁，此时负载偏心可得到大幅度的平衡，可以有效的减小衣物处理设备在脱水时的振动；另一方面，由于间隔壁12对液体的稳流作用及对液体产生的摩擦作用，液体会在腔室11a内呈现出沿周向均匀分布，而且液面波动会比较小，转动平衡装置的平衡负载偏心的性能得以大幅度提升。再者，根据注液量的不同，液体沿径向向内淹没一到多层间隔壁12后仍然会在周向上呈现出比较均匀的分布状态。由此可见，本申请实施例的转动平衡装置10，液体能够快速地、较为均匀地分布在转动本体11的腔室11a的周向，对负载偏心的平衡响应快，能够有效缩短衣物处理时间；此外，在转动平衡装置10转动速度较低的情况下，液体也能够较为均匀地分布在流道101中。
请参阅图8，如果没有设置本申请实施例的间隔壁，在转动平衡装置的转速较小时，液体会集中于一处，液面波动较大，从而转动平衡装置本身的振动较大，噪声也较大，对负载偏心的平衡响应效果比较差，延长转动平衡装置10对负载偏心的平衡响应时间，进而会延长衣物处理时间。
本申请一实施例中，衣物处理设备还可以包括注水件22，在转动平衡装置10转动过程中，注水件22能够独立地控制进入任一腔室11a中的注液量。例如，当负载偏心出现在内筒20的第一位置，则注水件22能够向该第一位置的反方向位置对应的腔室内注入液体，注液量可根据负载偏心程度来确定。注水件22可以安装于适当的位置，例如，安装于外筒或其他结构上。需要说明的是，为了使得衣物处理设备结构紧凑，也便于注水件22向腔室11a中注水，转动平衡装置10设置于内筒20的轴向一侧，且转动本体11的外径不超过内筒20的外径，如此，转动平衡装置不会在径向额外增大外筒21的尺寸；此外，注水件22可以伸入转动本体11的径向内侧，进而向腔室11a中注水，也就是说，内筒20不会干涉注水件22的注 水过程。
需要说明的是，所述的转动平衡装置10设置于内筒20的轴向一侧，指的是，同一个转动平衡装置10相对于内筒20的位置为内筒20轴向的一侧，而不是套设于内筒20的周向表面。
本申请实施例的衣物处理设备配置转动平衡装置10的数量不限，可以是一个或多个。请参阅图19，本申请一实施例中，转动平衡装置10的数量为两个，其中一个转动平衡装置10设置于内筒20的轴向一侧，其中另一个转动平衡装置10设置于内筒20的轴向另一侧。
请参阅图3和图5，腔室11a设置有过流通道11b，注水件22能够通过该过流通道11b向腔室11a中注液。本申请实施例中，过流通道11b构造为：在转动平衡装置10以不小于第一转速转动过程中，注水件22能够通过该过流通道11b向腔室11a内注入液体；在转动平衡装置10以小于第一转速转动过程中或转动平衡装置10处于静止条件下，腔室11a内的液体能够通过该过流通道11b排出腔室11a。也就是说，该过流通道11b具有注液功能也具有排液功能，如此可能简化转动平衡装置10的结构。示例性地，也可以在腔室11a的适当位置额外设置排液口。为了便于注水件22注水，腔室11a的朝向转动本体11的转动中心线的一侧敞开，敞开处形成为过流通道11b，过流通道11b的尺寸较大，且沿转动本体11的周向延伸，因此能够便于注水件22向腔室11a中注水。
需要说明的是，上述第一转速可以为转动平衡装置10所需的最低转速。
在一些实施例中，请参阅图9-图15，间隔壁12呈圆弧形，也就是说，流道101大致呈扇环形，间隔壁12对应的圆心O位于转动本体11的转动中心线上，相应的，多个流道101对应的圆心也位于转动本体11的转动中心线上，如此可以使得被间隔壁12间隔出的流道101中分布的液体具有较好的转动平衡性。上述的间隔壁12可以是一个，也可以是多个。
可以理解的是，多个流道101的排布方式包含多种情况，其中一种排布方式为：请参阅图12-图15，多个流道101均沿径向分布；其中另一种排布方式为：请参阅图4，多个流道101中的部分流道101沿径向分布，另一部分流道101沿周向分布，也就是说，同一圆周上，可以同时分布多个流道101。
沿转动本体11的径向排布的多个流道101的宽度可以相等，也可以不相等。在宽度相等的情况下，当腔室11a内的注液量较大时，液体在腔室11a内的分布比较均衡。在宽度不相等的情况下，需要说明的是，该情况指的是至少有一个流道101的宽度与其他流道101的宽度不相等的情况，请参阅图4，设流道101的沿径向的宽度为H，多个流道101中的宽度H的最大值为Hmax毫米，最小值为Hmin毫米，Hmax与Hmin的比值范围为：不小于1，且不超过5，即1≤Hmax/Hmin≤5，也就是说，最大的宽度不应超过最小的宽度的5倍，以兼顾液体分布的相对均匀性。
设转动平衡装置10所需的最低转速为n转每分钟，n与H的比值范围为：不小于5，且不超过40，即5≤n/H≤40。也就是说，每一流道101的宽度与转动平衡装置10的最低转速相关，该比例数值范围可以使得转动平衡装置10发挥较佳的平衡性能。需要说明的是，所述的最低转速指的是当转动平衡装置10的转速不小于该最低转速时，液体才能在离心力的作用下建立平衡作用，否则液体可能在自身重力作用下从腔室11a中排出。
一些实施例中，沿转动本体11的径向排布的流道101的数量为y，y的范围为：不小于2，且不超过11，即2≤y≤11，流道101的数量需控制在合理范围，以便于兼顾转动平衡装置10的外观尺寸。
一些实施例中，请参阅图13和图14，至少一间隔壁12形成有至少一个缺口12a，以将间隔壁12在周向上分成至少两段，被间隔壁12间隔出的沿径向布置的相邻两流道101内的液体可通过该缺口12a连通。进一步， 缺口12a对应的圆心角为γ，γ的范围为：不小于0.2°，且不超过3°，即0.2°≤γ≤3°，该圆心角的范围可以保障相邻流道101之间的液体流动，且也能够保障间隔壁12的稳流效果。
一些实施例中，请参阅图16-图18，间隔壁12上形成有至少一个贯穿间隔壁12的通孔121，被间隔壁12间隔出的相邻两流道101内的液体可通过该通孔121流通，该通孔121还能够起到排气作用。通孔121的形状不限，为兼顾液体流通和间隔壁12的稳流效果，本申请实施例中，通孔121呈圆形，通孔121的孔径为d，d的范围为：不小于1mm，且不超过3mm，即1mm≤d≤3mm。为便于液体能够及时高效地流通，通孔121的数量为x，x的范围为：不小于30，且不超过1000，即30≤x≤1000。
在一些实施例中，请参阅图4，至少一腔室11a内分隔有沿转动本体11的周向布置的多个子腔室11a’，多个子腔室11a’连通，至少一子腔室11a’内设置有上述的间隔壁12。腔室11a中的空间进一步地划分为更小空间的子腔室11a’，子腔室11a’之间相互连通，因此，无论液体从哪个子腔室11a’注入，在转动平衡装置10运行一段时间后，液体都会流入到其余几个子腔室11a’内。在此后的转动过程中，液体会在各个子腔室11a’内做均匀的分布，液体波动比较小；且在各个子腔室11a’之间的流动阻力增大，使得转动本体11转动至不同的方位时，液体在相邻子腔室11a’之间的流通量大为减少，平衡性能得以进一步提高。
请参阅图4和图6，腔室11a内具有沿转动本体11的径向延伸的第一壁面102和第二壁面103，间隔壁12设置在第一壁面102和第二壁面103之间。间隔壁12包括沿转动本体11转动方向相对设置的首端端部和末端端部；至少一间隔壁12的沿转动本体11的周向的首端端部与第一壁面102之间形成有第一间隔a1，该第一间隔a1可供液体流过，被该间隔壁12间隔出的相邻两流道101内的液体可通过该第一间隔a1流通。进一步地，该 第一间隔a1对应的圆心角为θ，θ的范围为：不小于0.1°，且不超过5°，即0.1°≤θ≤5°，θ的数值范围既能保障液体流过，又能使得间隔壁12具有较好的稳流效果。
请继续参阅图4和图6，至少一间隔壁12的末端端部与第二壁面103之间形成有第二间隔a2，同理，该第二间隔a2可供液体流过，被该间隔壁12间隔出的相邻两流道101内的液体可通过该第二间隔a2流通。进一步，第二间隔a2对应的圆心角为β，β的范围为：不小于0.1°，且不超过5°，即0.1°≤β≤5°，β的数值范围既能保障液体流过，又能使得间隔壁12具有较好的稳流效果。
上述的转动本体11的整体结构不限，只要能形成上述任一种的腔室11a即可。
请参阅图3和图5，示例性地，转动本体11包括环状主体部110以及位于环状主体部110内的多个分隔部111，多个分隔部111沿环状主体部110的周向间隔布置，以将环状主体部110的内部空间间隔出多个上述的腔室11a。该环状主体部110可以是一体成型结构，也可以是分体式结构并通过固定连接方式连接在一起。分隔部111可以是任何适当的形状，例如，本申请实施例中，分隔部111呈板状，环状主体部110的内壁与分隔部111的周缘连接。
请参阅图5，环状主体部110包括顶板1101、底板1102、以及位于转动本体11径向外侧的外围板1103，顶板1101、底板1102以及外围板1103共同围设成一环状空间，每一腔室11a为环状空间的一部分。环状空间的沿径向的内侧敞开，注水件22可以从该敞开处向各个腔室11a中注入液体，例如，注水件22保持静止不动，注水件22的注水口对准敞开位置，在转动本体11转动过程中，当转动本体11转动到注水件22的注水口与待注液的腔室11a对应时，注水件22向对应的腔室11a注水即可，该敞开处能够 延长注水件22向对应腔室11a内的注水时间，能够便于注水件22向腔室11a内注水。也就是说，本申请实施例中，该敞开处可以为上述的过流通道。
进一步地，请继续参阅图5，环状主体部110还包括设置于上述敞开处的框体1104，框体1104的边缘与顶板1101、底板1102以及两分隔部111连接，框体1104的中间区域形成有开口1104a，注水件22能够从该开口1104a处向对应的腔室11a注液，本实施例中，开口1104a形成为上述的过流通道11b。该框体1104的边缘能够在注水件22注液的初始阶段对注入的液体起到阻挡作用，减少液体从腔室11a中飞溅出来的量，提升注液效果。可以理解的是，该框体1104可以是一体成型结构，也可以是分体式结构。
进一步地，请参阅图4，子挡件13的沿转动本体11的径向外侧与外围板1103之间形成有供液体流过的第一间隙130，液体能够顺着外围板1103的内壁流过该第一间隙130，液体通过该第一间隙130可以流入或流出至相邻的子腔室11a’中。在转动本体11转动过程中，液体在离心力的作用下首先汇集于外围板1103的内壁，因此，该第一间隙130可以使得无论液体的量多还是量少，均能够通过该第一间隙130在相邻两子腔室11a’之间流通。
请参阅图4，在垂直于转动本体11转动中心线的平面内的投影，子挡件13的径向内侧位于环状主体部110内，也就是说，子挡件13的径向内侧边缘与环状主体部110的内侧边缘之间形成有第二间隙131。当注水件22向腔室11a内注水时，第二间隙131能够减少或避免阻挡注水件22喷出的液体，以提升注液效率。
请参阅图9和图10，一些实施例中，转动平衡装置10还包括设置于流道101中的子隔板14，该子隔板14能够至少部分地阻挡液体在流动中流动。也就是说，该子隔板14能够进一步增大液体在周向上的流动阻力，增大液体在腔室11a中分布的均衡性。本申请实施例中，子挡件13大致呈板状， 子挡件13的所在平面大致沿转动本体11的径向方向，以部分地阻挡液体在周向方向的流动。
示例性地，在沿转动本体11的径向排布多个间隔壁12的情况下，子隔板14设置于相邻两间隔壁12之间，如此，子隔板14可以在不影响液体沿转动本体11的径向外侧的内壁流动，即不影响沿外围板1103的内壁流动，不影响液体在相邻两子腔室11a’之间的流通。
以下对本申请的多个实施例的转动平衡装置10进行描述。
图1和图2为本申请一实施例的平衡装置的结构示意图；
图3-图18为本申请实施例的转动平衡装置的部分结构示意图。
实施例一：
请参阅图1-图7，环状主体部110对应的空间内设置有三个分隔部111，可以理解的是，分隔部111的数量可以是任意的。三个分隔部111将环状主体部110内的环状空间分隔为三个独立的腔室11a。
每一腔室11a内均设置有间隔壁12，如此能够使得转动平衡装置10具有较好的平衡性能。
每一腔室11a内均设置有多个子挡件13，使得每一腔室11a被分隔成多个子腔室11a’，每一子腔室11a’内均设置有多个间隔壁12。为便于描述，将与周向首端的分隔部111对应的子腔室11a’记为第一子腔室，将与周向末端的分隔部111对应的子腔室11a’记为第二子腔室，介于第一子腔室11a’和第二子腔室11a’之间的记为第三子腔室。
可以理解的是，上述的第一壁面102可以是分隔部111的表面，也可以是上述子挡件13的表面；同理，第二壁面103可以是分隔部111的表面，也可以是上述子挡件13的表面。
图6为第一子腔室的相关结构示意图，分隔部111的内壁为第一壁面102，对应的子挡件13的内壁为第二壁面103，间隔壁12的沿周向的首端 端部与分隔部111的内壁之间形成第一间隔a1，第一间隔a1对应的圆形角为θ。间隔壁12的沿周向的末端端部与子挡件13的内壁之间形成第二间隔a2，第二间隔a2对应的圆心角为β。
请参阅图4，在第二子腔室中，分隔部111的内壁为第二壁面103，对应的子挡件13的内壁为第一壁面102，间隔壁12的沿周向的首端端部与子挡件13的内壁之间形成第一间隔a1，间隔壁12的末端端部与分隔部111的内壁之间形成第二间隔a2。
在第三子腔室中，靠近周向首端的一子挡件13的内壁为第一壁面102，另一子挡件13的内壁为第二壁面103，间隔壁12的首端端部与其中一子挡件13的内壁之间形成第一间隔a1，间隔壁12的末端端部与其中另一子挡件13的内壁之间形成第二间隔a2。
相邻两流道101之间通过上述的第一间隔a1和第二间隔a2流通。
实施例二：
请参阅图9，实施例二的结构大致与实施例一相同，主要的不同之处在于：转动平衡装置10包括多个子隔板14，子隔板14设置于相邻两间隔壁之间，多个子隔板14不在同一平面内。
实施例三：
请参阅图10，实施例三的结构大致与实施例二相同，主要的不同之处在于：多个子隔板14位于同一平面内。
实施例四：
请参阅图11，实施例四的结构大致与实施例一相同，主要的不同之处在于：间隔壁12的末端端部延伸至第二壁面103处，在该实施例中，间隔壁12的首端端部与第一壁面102之间形成有第一间隔a1，间隔壁12的末端端部与第二壁面103之间没有形成间隔，即β＝0°。
实施例五：
请参阅图12，实施例五的结构大致与实施例一相同，主要的不同之处在于：间隔壁12的首端端部延伸至第一壁面102处，在该实施例中，间隔壁12的首端端部与第一壁面102之间没有形成间隔，即θ＝0°，间隔壁12的末端端部与第二壁面103之间形成有第二间隔a2。
实施例六：
请参阅图13，实施例六的结构大致与实施例一相同，主要的不同之处在于：腔室11a中没有设置子挡件。其中部分间隔壁12的首端端部延伸至第一壁面102处且末端端端与第二壁面103之间形成有第二间隔a2；其中另一部分间隔壁12的首端端部与第一壁面102之间形成有第一间隔a1且末端端部延伸至第二壁面103处。每一间隔壁12形成有缺口12a，不同的间隔壁的缺口12a对应不同的圆心角。
可以理解的是，在该第六实施例中，间隔壁12也可以不设置缺口12a。也可以是所有的间隔壁12的首端端部均延伸至第一壁面102处且末端端部与第二壁面103之间形成有第二间隔a2；还可以是所有的间隔壁12的首端端部与第一壁面102之间均形成有第一间隔a1且末端端部均延伸至第二壁面103处。
实施例七：
请参阅图14，实施例七的结构大致与实施例六相同，主要的不同之处在于：每一间隔壁12形成有多个缺口12a，多个间隔壁12对应的缺口12a对应同一圆心角。
实施例八：
请参阅图15，实施例八的结构大致与实施例七相同，主要的不同之处在于：间隔壁12上没有设置上述的缺口12a。

可以理解的是，在间隔壁12的首端端部与第一壁面102形成有第一间隔a1，和/或，间隔壁12的末端端部与第二壁面103之间形成有上述的第二间隔a2的情况下，也可以在间隔壁12上设置上述的通孔121。
实施例十：
请参阅图17，实施例十的结构大致与实施例九相同，主要的不同之处在于：多个通孔121沿间隔壁12的周向布置。
实施例十一：
请参阅图18，实施例十的结构大致与实施例九相同，主要的不同之处在于：间隔壁12上的通孔121的数量远远多于实施例九中的通孔121的数量，且本实施例中的通孔121的孔径小于实施例九中的通孔121的孔径。本实施例中，多个通孔121能够满足液体在相邻两个流道101之间流动，注液时液体在离心力作用下，能够通过多个通孔121快速流动，进而流动至最外侧的流道101中；排液时，液体在自身重力作用下可以通过通孔121排出腔室11a。
本申请提供的各个实施例/实施方式在不产生矛盾的情况下可以相互组合。
以上所述仅为本申请的较佳实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
