技术领域
本申请属于家用电器技术领域，更具体地，涉及一种波轮组件和衣物处理设备。
背景技术
相关的波轮式洗衣机和搅拌式洗衣机均被用户所喜爱，且两种类型的洗衣机各有自身的优势。波轮洗衣机洗衣桶底部的波轮正反旋转，带动衣物上下左右不停地翻转，使衣物之间、衣物与桶壁、衣物与波轮之间进行摩擦从而去污清洗。搅拌式洗衣机在洗衣桶底部的波轮中央装有搅拌棒，波轮正反旋转并带动装在洗衣桶中央的搅拌棒旋转，从而带动机身内水流及衣服运动；运动中的水流推动衣服不停地翻转，使衣服之间、衣服与桶壁及搅拌棒之间，在水中进行摩擦，并在洗涤剂的作用下实现去污清洗。
相关的搅拌式洗衣机的搅拌棒与波轮为可拆卸连接，从而根据用户洗涤需求随时在搅拌式洗衣机和波轮式洗衣机之间切换。相关的搅拌棒与波轮通过连接结构实现固定连接，但是，在洗衣机转动的过程中连接结构承担了较大的旋转阻力，连接结构的强度一般不太高，容易造成搅拌棒和波轮的连接可靠性风险。
发明内容
有鉴于此，本申请提供一种波轮组件和衣物处理设备，以解决如何提升搅拌棒与波轮的连接可靠性的技术问题。
本申请的技术方案是这样实现的：
本申请实施例提供一种波轮组件，包括：波轮，可绕轴向转动；搅拌棒，所述搅拌棒与所述波轮可拆卸地同轴连接；其中，所述波轮和所述搅拌棒上均设置连接结构和定位结构；所述连接结构允许所述波轮与所述搅拌棒之间的沿第一方向运动以连接和脱离连接，所述定位结构限定所述波轮与所述搅拌棒在连接状态下的位置；所述第一方向对应贯穿所述波轮和所述搅拌棒的径向，且所述第一方向与所述径向的夹角为第一预设锐角或所述第一方向为所述径向。
本申请实施例还提供一种衣物处理设备，包括：桶体，所述桶体具有用于容纳衣物的容纳腔；上述任一项所述的波轮组件，位于所述容纳腔内且所述波轮连接在所述桶体的底部。
本申请实施例提供一种波轮组件，包括波轮和搅拌棒。波轮可绕轴向转动；所述搅拌棒与所述波轮可拆卸地同轴连接；其中，所述波轮和所述搅拌棒上均设置连接结构和定位结构；所述连接结构允许所述波轮与所述搅拌棒之间的沿径向的相对运动以连接和脱离连接，所述定位结构限定所述波轮与所述搅拌棒在连接状态下的位置；所述第一方向对应贯穿所述波轮和所述搅拌棒的径向，且所述第一方向与所述径向的夹角为第一预设锐角或所述第一方向为所述径向。本申请实施例的搅拌棒与波轮可拆卸地同轴连接，从而用户可根据实际洗涤需要自行将搅拌棒拆卸或安装于波轮；波轮和搅拌棒上均设置连接结构和定位结构，从而连接结构和定位结构可对波轮和搅拌棒的连接进行双重限位，分散承担阻力；通过连接结构和定位结构，即连接结构允许波轮与搅拌棒之间的沿第一方向的相对运动以连接和脱离连接，从而在连接结构的限制下，波轮与搅拌棒可沿第一方向相对运动的连接，而定位结构限定波轮与搅拌棒在连接状态下的位置，从而搅拌棒与波轮不易产生相对运动，搅拌棒与波轮的连接可以 更加稳固，提升了波轮和搅拌棒的连接可靠性。第一方向与波轮和搅拌棒的径向的夹角可以为第一预设锐角，那么，搅拌棒可相对波轮斜向上或斜向下运动，搅拌棒的周侧设置有洗衣桶，在拆卸搅拌棒时，用户可施加斜向上的力拉动搅拌棒运动，使得搅拌棒与波轮脱离连接，此时由于搅拌棒斜向上运动，搅拌棒的运动空间较大，不易受到洗衣桶桶壁的限制，便于搅拌棒与波轮的拆卸，并且用户用手提拉时，斜向上拉动搅拌棒便于人体肌肉发力，符合人体力学的设定。在将搅拌棒和波轮安装时，用户可施加斜向下的力推动搅拌棒运动，使得搅拌棒与波轮连接，并且搅拌棒的重力作用也使得其自身具有向下的趋势，从而也便于搅拌棒与波轮的安装。通过连接结构和定位结构的共同作用，可使得波轮和搅拌棒的连接稳固，从而波轮在带动搅拌棒一起旋转时，用于波轮和搅拌棒限位的结构不易断裂，从而搅拌棒和波轮可以稳定限位并一起旋转。

需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个…”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。“多个”表示大于或等于两个。
本申请实施例提供一种波轮组件和衣物处理设备。本申请实施例所述的波轮组件可应用于搅拌式洗衣机和波轮式洗衣机，波轮和搅拌棒安装时，即为搅拌式洗衣机；波轮和搅拌棒拆卸时，即为波轮式洗衣机。波轮和搅拌棒上均设置连接结构和定位结构；连接结构允许波轮与搅拌棒之间的沿径向的相对运动以连接和脱离连接，定位结构限定波轮与搅拌棒在连接状态下的径向位置，连接结构和定位结构双重限位，使得波轮和搅拌棒的连接可更加稳固，提升了波轮和搅拌棒的连接可靠性。可以理解，洗衣机包括具有单独洗涤功能的单洗洗衣机，也包括具有洗涤和脱水功能的洗衣机，也包括具有洗涤和烘干功能的洗烘一体机。
如图1-2和图9-10所示，本申请实施例提供一种波轮组件10，波轮组件10包括波轮1和搅拌棒2。其中，波轮1可绕轴向转动；搅拌棒2与波轮1可拆卸地同轴连接，即搅拌棒2与波轮1同轴设置，搅拌棒2与波轮1可拆卸地连接，在波轮1与搅拌棒2连接的状态下，波轮1可绕轴向旋转，可带动搅拌棒2一起绕轴向旋转。搅拌棒2的侧壁还设置几片搅拌翼，能够保持在360°之内依据不同衣物质地、脏污程度、洗涤物质量等或快或慢地来回旋转，将衣物揽在怀中来回揉搓，彻底清除污渍。
在第一实施例中，如图1和图2所示，波轮1和搅拌棒2上均设置连接结构3和定位结构4，以实现波轮1和搅拌棒2可拆卸地连接；连接结构3允许波轮1与搅拌棒2之间的沿径向的相对运动以连接和脱离连接，可以理解，连接结构3允许波轮1与搅拌棒2之间的沿径向的相对运动，例如，当波轮1的 连接结构3与搅拌棒2的连接结构3沿径向相对运动至具有重合部分时，波轮1与搅拌棒2连接；当波轮1的连接结构3与搅拌棒2的连接结构3沿径向相对运动至没有重合部分时，波轮1与搅拌棒2脱离连接。定位结构4限定波轮1与搅拌棒2在连接状态下的径向位置，可以理解，在波轮1与搅拌棒2处于连接状态时，波轮1与搅拌棒2之间仍可沿径向相对运动以脱离连接，而定位结构4可限定波轮1与搅拌棒2沿径向的相对运动，从而限定波轮1与搅拌棒2在连接状态下的径向位置，从而波轮1与搅拌棒2的连接可以更加稳固，而不易沿径向产生相对运动。
本申请实施例的搅拌棒与波轮可拆卸地同轴连接，从而用户可根据实际洗涤需要自行将搅拌棒拆卸或安装于波轮；波轮和搅拌棒上均设置连接结构和定位结构，从而连接结构和定位结构可对波轮和搅拌棒的连接进行双重限位，分散承担阻力；通过连接结构和定位结构，即连接结构允许波轮与搅拌棒之间的沿径向的相对运动以连接和脱离连接，从而在连接结构的限制下，波轮与搅拌棒可沿径向相对运动的连接，而定位结构限定波轮与搅拌棒在连接状态下的径向位置，从而搅拌棒与波轮不易产生相对运动，搅拌棒与波轮的连接可以更加稳固，提升了波轮和搅拌棒的连接可靠性。
在一些实施例中，如图1和图2所示，连接结构3包括在搅拌棒2的轴向一端以及在波轮1的轴向一端设置的榫卯结构31，从而搅拌棒2的轴向一端设置的榫卯结构31与波轮1的轴向一端设置的榫卯结构31可以连接和脱离连接，榫卯结构31位于波轮1的中间区域，从而搅拌棒2通过榫卯结构31连接在波轮1的中间区域，当用于衣物处理设备时，搅拌棒2位于桶体的中间区域，从而在洗涤衣物时，桶体内的衣物与搅拌棒2之间的摩擦受力是比较均匀的。榫卯结构31对应贯穿搅拌棒2和波轮1的径向，即榫卯结构31对应贯穿搅拌棒2和波轮1所形成的整体结构的径向，例如，搅拌棒2的榫卯结构31沿径向贯穿波轮1的榫卯结构31；或，波轮1的榫卯结构31沿径向贯穿搅拌棒2的榫卯结构31，从而实现波轮1与搅拌棒2之间的沿径向的相对运动。结合图3和图4所示，定位结构4包括定位销41和定位孔42，定位销41和定位孔42设 置于榫卯结构31外侧，定位销41可插入定位孔42，从而限定波轮1与搅拌棒2在连接状态下的径向位置。
榫卯结构连接是在两个构件上所采用的一种凹凸结合的连接方式。凸出部分叫榫(或榫头)；凹进部分叫卯(或榫眼、榫槽、凹槽)，榫和卯咬合，起到连接作用。榫卯结构是榫(榫头)和卯(凹槽)的结合，是构件之间多与少、高与低、长与短之间的巧妙组合，可有效地限制木件向各个方向的扭动。最基本的榫卯结构由两个构件组成，其中一个的榫头插入另一个的卯眼中，使两个构件连接并固定。榫头伸入卯眼的部分被称为榫舌，其余部分则称作榫肩。
本申请实施例的连接结构包括在搅拌棒的轴向一端以及在波轮的轴向一端设置的榫卯结构，榫卯结构对应贯穿搅拌棒和波轮的径向，从而波轮与搅拌棒可沿径向相对运动，以实现波轮与搅拌棒之间的连接和脱离连接；定位结构包括定位销和定位孔，即定位销可插入定位孔，从而限定波轮与搅拌棒在连接状态下的径向位置，从而搅拌棒与波轮不易产生相对运动，搅拌棒与波轮的连接可以更加稳固，提升了波轮和搅拌棒的连接可靠性。
在一些实施例中，如图4和图5所示，搅拌棒2包括本体21、第一伸缩杆23和榫头25。其中，本体21内具有空腔22；第一伸缩杆23位于空腔22内，第一伸缩杆23与本体21同轴设置，且第一伸缩杆23可沿轴向与本体21产生相对平动；定位销41连接于第一伸缩杆23，因此定位销41可随第一伸缩杆23一起沿轴向与本体21产生相对平动；定位销41突出于本体21轴向的第一端24，第一端24是指本体21沿轴向靠近波轮1的一端；榫头25用于与波轮1上开设的凹槽11连接成榫卯结构31的连接，即榫头25沿径向滑入凹槽11内，从而连接成榫卯结构31的连接；榫头25轴向突出于本体21的第一端24设置，榫头25从本体21的径向的一端延伸至另一端，定位销41位于榫头25径向外侧。
本申请实施例的搅拌棒包括本体、第一伸缩杆和榫头，第一伸缩杆可沿轴向与本体产生相对平动，定位销连接于第一伸缩杆，因此定位销可随第一伸缩杆一起沿轴向与本体产生相对平动，榫头用于与波轮上开设的凹槽连接成榫卯 结构的连接；例如，在将搅拌棒从波轮拆卸时，先撤去定位销对波轮与搅拌棒在连接状态下径向位置的限定，再拆卸榫卯结构；在将搅拌棒安装于波轮时，先向远离波轮的方向拉动第一伸缩杆以带动定位销一起向远离波轮的方向运动，从而定位销对榫头的径向滑动不干涉，在榫卯结构连接到位后，释放第一伸缩杆即可将定位销插入定位孔中以限定波轮与搅拌棒在连接状态下的径向位置，同时安装到位。因此，在将搅拌棒从波轮拆卸或将搅拌棒安装于波轮时，可向远离波轮的方向拉动第一伸缩杆以带动定位销一起向远离波轮的方向运动，从而避免定位销对榫卯结构的连接和拆卸造成干涉。
在一些实施例中，如图2和图4所示，榫头25包括梯形部261，梯形部261在轴向的一端为榫头25远离本体21的一端，梯形部261在轴向的另一端为榫头25与本体21连接的一端；梯形部261从一端到轴向上的另一端，横截面积减小，对应的，波轮1上开设的凹槽11在轴向上从靠近搅拌棒2的一端到远离搅拌棒2的另一端，横截面积增大，从而当榫头25与波轮1上开设的凹槽11连接成榫卯结构31的连接时，即榫头25沿径向滑入凹槽11内与凹槽11配合后，榫头25不易沿轴向移动而脱离，具体在于，当榫头25沿轴向凹槽11开口端的方向移动时，由于凹槽11的横截面积随靠近开口端逐渐变小，从而凹槽11对榫头25横截面积相对更大的部分造成了轴向移动限制，从而榫头25无法沿轴向移动并限定在凹槽11内。并且，榫头25沿径向滑入凹槽11内与凹槽11配合后，搅拌棒2和波轮1在榫卯结构31的连接下，也难以沿周向旋转运动。
本申请实施例的榫头包括梯形部，梯形部从一端到轴向上的另一端，横截面积减小，对应的，波轮上开设的凹槽在轴向上从靠近搅拌棒的一端到远离搅拌棒的另一端，横截面积增大，从而当榫头沿轴向凹槽开口端的方向移动时，由于凹槽的横截面积随靠近开口端逐渐变小，从而凹槽对榫头横截面积相对更大的部分造成了轴向移动限制，从而榫头无法沿轴向移动并限定在凹槽内，从而在轴向上对搅拌棒和波轮进行了限制。
在一些实施例中，如图2和图3示，凹槽11在轴向的一端为凹槽11靠近 本体21的开口端；凹槽11从开口端到轴向上的封闭端，横截面积增大。也就是说，凹槽11在轴向的开口端的横截面积较小，在轴向上的封闭端的横截面积较大，从而当榫头25与波轮1上开设的凹槽11连接成榫卯结构31的连接时，即榫头25沿径向滑入凹槽11内与凹槽11配合后，榫头25不易沿轴向移动而脱离，具体在于，当榫头25沿轴向凹槽11开口端的方向移动时，由于凹槽11的横截面积随靠近开口端逐渐变小，从而凹槽11对榫头25横截面积相对更大的部分造成了轴向移动限制，从而榫头25无法沿轴向移动并限定在凹槽11内。
在一些实施例中，如图2和图4所示，第一伸缩杆23包括把手231和杆体232。其中，把手231在轴向上与本体21之间设置可伸缩地第一弹性件27，例如，第一弹性件27可以为弹簧等；杆体232与把手231同轴设置且连接在把手231远离第一弹性件27的一侧，杆体232远离把手231的一端连接定位销41。其中，当搅拌棒2与波轮1连接时，第一弹性件27初始状态为压缩状态，第一弹性件27抵压第一伸缩杆23使得定位销41稳定插入定位孔42中，以限定波轮1与搅拌棒2在连接状态下的径向位置，从而搅拌棒2和波轮1稳定连接；在将搅拌棒2从波轮1拆卸或将搅拌棒2安装于波轮1时，可向远离波轮1的方向拉动第一伸缩杆23以带动定位销41一起向远离波轮1的方向运动，此时第一弹性件27进一步被压缩，在将榫卯结构31安装或拆卸到位时，释放第一伸缩杆23，第一弹性件27恢复原状，并抵压第一伸缩杆23，使得定位销41插入定位孔42内，搅拌棒2即安装到位；或榫卯结构31拆卸后释放第一伸缩杆23，同时拆卸完成。
本申请实施例的第一伸缩杆包括把手和杆体，把手在轴向上与本体之间设置可伸缩地第一弹性件，当搅拌棒与波轮连接时，第一弹性件初始状态为压缩状态，第一弹性件抵压第一伸缩杆使得定位销稳定插入定位孔中，从而搅拌棒和波轮稳定连接；在将搅拌棒从波轮拆卸或将搅拌棒安装于波轮时，可向远离波轮的方向拉动第一伸缩杆以带动定位销一起向远离波轮的方向运动，此时第一弹性件进一步被压缩，在将榫卯结构安装或拆卸到位时，释放第一伸缩杆，第一弹性件恢复原状，并抵压第一伸缩杆，使得定位销插入定位孔内，搅拌棒 即安装到位；或榫卯结构拆卸后释放第一伸缩杆，同时拆卸完成。第一弹性件的抵压保证了搅拌棒和波轮在轴向上能够稳定连接，以及在将榫卯结构安装或拆卸到位时，为避免定位销干涉榫卯结构的连接而被拉动的第一伸缩杆能够在第一弹性件的抵压下恢复原状，保证定位销和定位孔也能安装或拆卸到位。
在一些实施例中，如图3所示，波轮1包括底板12和连接凸块14。其中，底板12沿轴向设置有多个旋叶13，且多个旋叶13沿周向均匀设置，在波轮1旋转时，多个旋叶13增加了衣物与波轮1之间的摩擦力，从而衣物与波轮1进行摩擦而去污清洗。连接凸块14位于波轮1的中心位置，连接凸块14用于与搅拌棒2可拆卸地连接，多个旋叶13绕连接凸块14设置；其中，连接凸块14开设贯穿径向的凹槽11，凹槽11的壁面可与榫头25壁面抵接，从而限定榫头25相对于波轮1的周向旋转；连接凸块14上设置位于凹槽11外侧的定位孔42，定位孔42包括多个，例如两个，且两个定位孔42位于凹槽11的两侧。
本申请实施例的波轮包括底板和连接凸块，多个旋叶增加了衣物与波轮之间的摩擦力，从而衣物与波轮进行摩擦而去污清洗；连接凸块开设贯穿径向的凹槽，凹槽的壁面可与榫头壁面抵接，从而限定榫头相对于波轮的周向旋转；并且榫头在轴向上的移动也受到自身的限制，连接凸块上设置位于凹槽外侧的定位孔，当定位销插入定位孔后，可限制榫头相对于凹槽的径向移动，从而搅拌棒和波轮在周向，轴向，径向均受到限制，且衣服与搅拌棒之间在水中进行摩擦，导致搅拌棒受到的较大的旋转阻力由榫卯结构承担，而榫卯结构具有足够的结构强度，使得波轮和搅拌棒的连接更加稳固，并且实际上搅拌棒受到的沿凹槽延伸方向的径向力是较小的，因此定位销和定位孔所连接的定位结构足以支撑搅拌棒和波轮的连接。
在一些实施例中，如图6所示，波轮1还包括榫卯销5，榫卯销5可填充凹槽11并与连接凸块14可拆卸地连接。榫卯销5允许波轮1与搅拌棒2之间的沿径向的相对运动以连接和脱离连接，且榫卯销5限定波轮1与搅拌棒2沿径向的相对运动，从而限定波轮1与搅拌棒2在连接状态下的径向位置。本申请实施例的波轮还包括榫卯销，榫卯销可填充凹槽并与连接凸块可拆卸地连接， 从而当搅拌棒拆除后波轮上产生的空隙可由榫卯销可拆除式插入，以防止空隙处缠绕衣物。
在一些实施例中，如图6和图7所示，榫卯销5包括销主体51、第二伸缩杆52和第二弹性件53。榫卯销5的外形类似于榫头的结构。其中，结合图3和图8所示，销主体51具有沿轴向的第一通孔57，销主体51的侧壁可与凹槽11抵接，从而限定销主体相对于波轮的周向旋转，使得销主体相对于波轮稳定沿径向移动；第二伸缩杆52贯穿第一通孔57且可沿轴向运动；第二弹性件53套设在第二伸缩杆52外且位于第一通孔57内，第二弹性件53的两端分别与销主体51和第二伸缩杆52抵接，第二弹性件53在初始状态下处于压缩状态，并抵压销主体51和第二伸缩杆52处于初始位置，当第二伸缩杆52沿轴向运动时，带动第二弹性件53运动并进一步被压缩，当释放第二伸缩杆52时，第二弹性件53恢复并带动第二伸缩杆52一起恢复至初始状态。当销主体51和第二伸缩杆52处于初始位置时，第二伸缩杆52突出于销主体51靠近波轮1的一端，第二伸缩杆52突出于销主体51的部分可插入波轮1的中心孔内，以限定波轮1与榫卯销5沿径向的相对运动，从而限定波轮1与榫卯销5在连接状态下的径向位置。在安装或拆卸榫卯销5时，都需要先沿远离波轮1的方向拉动第二伸缩杆52，使第二伸缩杆52不突出于销主体51，再沿径向滑动将销主体51安装到凹槽11内。
本申请实施例的榫卯销包括销主体、第二伸缩杆和第二弹性件，销主体的侧壁可与凹槽抵接，从而限定销主体相对于波轮的周向旋转，使得销主体相对于波轮稳定沿径向移动；第二伸缩杆突出于销主体靠近波轮的一端，第二伸缩杆突出于销主体的部分可插入波轮的中心孔内，以限定波轮与榫卯销沿径向的相对运动，从而限定波轮与榫卯销在连接状态下的径向位置；第二弹性件的抵压保证了榫卯销和波轮在轴向上能够稳定连接，以及在将销主体安装或拆卸到位时，为避免第二伸缩杆的突出部分干涉销主体和凹槽的连接而被拉动的第二伸缩杆能够在第二弹性件的抵压下恢复原状，保证第二伸缩杆的突出部分和波轮中心孔也能安装或拆卸到位。
在一些实施例中，如图6和图7所示，销主体51与第一通孔57相邻的壁面呈台阶状，第二伸缩杆52包括柱体部521和手柄部522。其中，柱体部521的侧壁设置向外延伸的凸起部523，凸起部523在轴向上抵接于销主体51与第一通孔57相邻的壁面一端的台阶处，销主体51与第一通孔57相邻的壁面的台阶处在轴向上具有两端，因此，第二伸缩杆52在凸起部523的限制下，在销主体51与第一通孔57相邻的壁面的台阶处的两端空间内移动；手柄部522连接在柱体部521的轴向上远离波轮1的一端，拉动手柄部522，可带动柱体部521和凸起部523一起沿轴向运动；其中，第二弹性件53套设在柱体部521的侧壁外，且第二弹性件53抵接在凸起部523和另一端的台阶处之间，即第二弹性件53位于销主体51与第一通孔57相邻的壁面的台阶处的两端空间内。
本申请实施例的第二伸缩杆包括柱体部和手柄部，柱体部的侧壁设置向外延伸的凸起部，凸起部在轴向上抵接于销主体与第一通孔相邻的壁面一端的台阶处，第二弹性件抵接在凸起部和销主体与第一通孔相邻的壁面另一端的台阶处之间，从而第二弹性件通过抵压凸起部从而抵压柱体部稳定处于初始位置，使得柱体部突出于销主体的部分可稳定插入波轮的中心孔内，从而实现稳定限位；手柄部的设置便于用于手持手柄部以拉动柱体部沿轴向运动。
在第二实施例中，如图9和图10所示，波轮1和搅拌棒2上均设置连接结构3和定位结构4，以实现波轮1和搅拌棒2可拆卸地连接；连接结构3允许波轮1与搅拌棒2之间的沿第一方向运动以连接和脱离连接，第一方向如图10所示的L1方向。波轮1设置的连接结构3和搅拌棒2上设置的连接结构3相互配合并可拆卸地连接，从而实现波轮1和搅拌棒2可拆卸地连接。如图9和图10所示，定位结构4限定波轮1与搅拌棒2在波轮1与搅拌棒2的连接结构3在连接状态下的位置，可以理解，在波轮1与搅拌棒2的连接结构3处于连接状态时，波轮1与搅拌棒2之间仍可沿第一方向运动以脱离连接，而定位结构4可限定波轮1与搅拌棒2在连接结构3连接状态下的位置，从而当定位结构4限定到位时，波轮1与搅拌棒2无法再沿第一方向运动以脱离连接，从而波轮1与搅拌棒2的连接可以更加稳固，而不易沿第一方向产生相对运动。
如图9和图10所示，第一方向对应贯穿波轮1和搅拌棒2的径向，对应是指波轮1上设置的连接结构3贯穿波轮1的径向，搅拌棒2上的连接结构3贯穿搅拌棒2的径向。第一方向与径向的夹角为第一预设锐角，径向方向如图10所示的L2方向，第一预设锐角如图10所示的θ角。在拆卸搅拌棒2时，用户可施加斜向上的力拉动搅拌棒2运动，使得搅拌棒2与波轮1的连接结构3脱离连接；在将搅拌棒2和波轮1安装时，用户可施加斜向下的力推动搅拌棒2运动，使得搅拌棒2的连接结构3与波轮1的连接结构3连接。
本申请实施例的搅拌棒与波轮可拆卸地同轴连接，从而用户可根据实际洗涤需要自行将搅拌棒拆卸或安装于波轮；例如，在将搅拌棒和波轮拆卸时，首先拆卸定位结构，再拆卸连接结构，使得搅拌棒与波轮之间可沿第一方向运动以脱离连接；由于第一方向与波轮和搅拌棒的径向的夹角为第一预设锐角，那么，搅拌棒可相对波轮斜向上或斜向下运动，搅拌棒的周侧设置有洗衣桶，在拆卸搅拌棒时，用户可施加斜向上的力拉动搅拌棒运动，使得搅拌棒与波轮脱离连接，此时由于搅拌棒斜向上运动，搅拌棒的运动空间较大，因此不易受到洗衣桶桶壁的限制，便于搅拌棒与波轮的拆卸，并且用户用手提拉时，斜向上拉动搅拌棒便于人体肌肉发力，符合人体力学的设定。在将搅拌棒和波轮安装时，用户可施加斜向下的力推动搅拌棒运动，使得搅拌棒与波轮连接，并且搅拌棒的重力作用也使得其自身具有向下的趋势，从而也便于搅拌棒与波轮的安装。通过连接结构和定位结构的共同作用，可使得波轮和搅拌棒的连接稳固，从而波轮在带动搅拌棒一起旋转时，用于波轮和搅拌棒限位的结构不易断裂，从而搅拌棒和波轮可以稳定限位并一起旋转。
在一些实施例中，如图9和图10所示，第一预设锐角θ在15度到45度之间。例如，第一预设锐角θ可以是25度。第一预设锐角θ不宜过小，否则可能导致用户在拆装搅拌棒2与波轮1时，大致沿径向方向将搅拌棒2拔出，因此用户在拆装搅拌棒时容易受到洗衣桶桶壁的限制，从而不方便用户操作；第一预设锐角θ也不宜过大，否则当搅拌棒2与波轮1的连接结构3连接时，使得搅拌棒2具有容易沿第一方向向一侧运动的趋势，例如，在横向方向上第一方 向的低位一侧，从而导致搅拌棒2与波轮1的连接结构3在连接状态时不易保持平衡，还具有较强的运动趋势，从而就需要强度较高的定位结构来进行定位，若是第一预设锐角θ过大，连接结构3设置得太陡的话，定位结构4克服重力作用实现波轮1与搅拌棒2定位所需要的力也大，因此，长期使用下来，容易导致定位结构断裂失效。
本申请实施例的第一预设锐角在15度到45度之间，第一预设锐角的大小是较为合适的，从而搅拌棒可沿第一方向斜向上运动以脱离与波轮的连接，便于用户操作；搅拌棒相对于波轮具有一定的斜向下运动的趋势，但是由于第一预设锐角的大小合适，其斜向下运动的趋势较小，从而定位结构定位时所需承受的力也较小，定位结构可以较好地保持搅拌棒与波轮在连接状态时的位置，从而使得搅拌棒与波轮在便于拆装的同时，其连接强度也较为可靠。
在一些实施例中，如图9和图10所示，连接结构3的宽度沿第一方向单调变化，单调变化是指连接结构3的宽度沿第一方向一直变大或一直变小，只不过变化值不是恒定的。连接结构3的宽度随连接结构3的在轴向上高度增加而增加，宽度所在方向垂直于第一方向，第一方向可以大致理解为连接结构3的长度延伸方向，宽度所在方向如图11所示的L3方向。可以理解，连接结构3在轴向上的高位，其宽度较大，连接结构3在轴向上的低位，其宽度较小。在安装波轮1和搅拌棒2时，搅拌棒2的连接结构3只能从宽度较大的一端插入波轮1的连接结构3内，即只能从连接结构3在轴向上的高位向低位运动来进行安装，即斜向下运动安装，直至移动到宽度较小的一端时，搅拌棒2的连接结构3无法再移动，从而可使得搅拌棒2与波轮1的连接结构3连接到位，并且可保持搅拌棒2斜向下运动的平衡；在拆卸波轮1和搅拌棒2时，搅拌棒2的连接结构3从宽度较小的一端向宽度较大的一端移动，从而脱离出波轮1的连接结构3内，即从连接结构3在轴向上的低位向高位运动，即斜向上运动以进行拆卸。
本申请实施例的连接结构在轴向上的低位一端的宽度较小，可以对搅拌棒相对于波轮斜向下运动的趋势进行限位，在一定程度上保证搅拌棒与波轮的连 接结构连接到位时的平衡；并且波轮的连接结构只有一端可以插入或脱离，从而可以对用户的操作进行防错，使得用户按照符合人体力学的操作方法拆装搅拌棒和波轮。
在一些实施例中，如图9和图10所示，连接结构3包括在搅拌棒2的轴向一端以及在波轮1的轴向一端设置的榫卯结构31，从而搅拌棒2的轴向一端设置的榫卯结构31与波轮1的轴向一端设置的榫卯结构31可以连接和脱离连接，榫卯结构31位于波轮1的中间区域，从而搅拌棒2通过榫卯结构31连接在波轮1的中间区域，当用于衣物处理设备时，搅拌棒2位于桶体的中间区域，从而在洗涤衣物时，桶体内的衣物与搅拌棒2之间的摩擦受力是比较均匀的。结合图11和图12所示，定位结构4位于对应的榫卯结构31内，即定位结构4分布于榫卯结构31的范围内，那么当波轮1与搅拌棒2的榫卯结构31连接到位时，可以将定位结构4安装到位，从而可以将波轮1与搅拌棒2在榫卯结构31范围内进行定位，从而限定波轮1与搅拌棒2在榫卯结构31的连接状态下的位置。
榫卯结构连接是在两个构件上所采用的一种凹凸结合的连接方式。凸出部分叫榫(或榫头)；凹进部分叫卯(或榫眼、榫槽、凹槽)，榫和卯咬合，起到连接作用。榫卯结构是榫(榫头)和卯(凹槽)的结合，是构件之间多与少、高与低、长与短之间的巧妙组合，可有效地限制木件向各个方向的扭动。最基本的榫卯结构由两个构件组成，其中一个的榫头插入另一个的卯眼中，使两个构件连接并固定。榫头伸入卯眼的部分被称为榫舌，其余部分则称作榫肩。
本申请实施例的连接结构包括在搅拌棒的轴向一端以及在波轮的轴向一端设置的榫卯结构，从而波轮与搅拌棒可沿第一方向相对运动，以实现波轮与搅拌棒之间的连接和脱离连接，榫卯结构连接使得波轮和搅拌棒整体结构更加牢固；定位结构位于对应的榫卯结构内，从而限定波轮与搅拌棒在榫卯结构连接状态下的位置，从而搅拌棒与波轮不易在第一方向产生相对运动，搅拌棒与波轮的连接可以更加稳固，提升了波轮和搅拌棒的连接可靠性。定位结构位于对应的榫卯结构内，从而两者不易由于距离较远而损失较大的力矩，两者的连接 强度更加可靠，可以承受更大的旋转阻力。
在一些实施例中，如图12和图13所示，搅拌棒2包括包括本体21、第一伸缩杆23和榫头25。榫头25可与本体21可拆卸地连接，以更换合适尺寸的榫头25。其中，结合图10所示，本体21内具有沿轴向延伸的空腔22；榫头25用于与波轮1上开设的凹槽11形成榫卯结构31的连接，即榫头25沿第一方向滑入凹槽11内，从而连接成榫卯结构31的连接；榫头25沿轴向突出于本体21的第一端24设置，第一端24是指本体21沿轴向靠近波轮1的一端，榫头25远离本体21的端面S沿第一方向延伸；结合图11和图14所示，榫头25内部设有沿轴向延伸且与空腔22连通的第二通孔262，第二通孔262贯穿榫头25；第一伸缩杆23可沿空腔22和第二通孔262运动，以在突出于榫头25的定位状态和缩回第二通孔262或空腔22内的解锁状态之间切换；空腔22内可设置管状结构28，使得第一伸缩杆23在管状结构28内运动，从而对第一伸缩杆23的运动进行导向。其中，在定位状态下，第一伸缩杆23突出榫头25的部分与波轮1的凹槽11内部开设的定位孔15形成定位结构4的连接。可以理解，在定位状态时，第一伸缩杆23穿过空腔22和第二通孔262并突出于榫头25，以插入定位孔15内，从而限定波轮1与搅拌棒2的榫卯结构31在连接状态下的位置；在解锁状态时，第一伸缩杆23缩回第二通孔262或空腔22内，此时波轮1与搅拌棒2不受定位结构4的限制，波轮1与搅拌棒2的榫卯结构31可沿第一方向运动以连接和脱离连接。
本申请实施例的搅拌棒包括本体、第一伸缩杆和榫头，榫头用于与波轮上开设的凹槽连接成榫卯结构的连接，榫卯结构连接使得波轮和搅拌棒连接牢固；第一伸缩杆可沿空腔和第二通孔运动，以在突出于榫头的定位状态和缩回第二通孔或空腔内的解锁状态之间切换；在定位状态下，第一伸缩杆突出榫头的部分与波轮的凹槽内部开设的定位孔形成定位结构的连接；因此，通过第一伸缩杆沿轴向的来回伸缩，即可控制波轮与搅拌棒在榫卯结构连接状态下的定位，结构简单，并且操作方便，方便用户拆装。
在一些实施例中，如图13和图14所示，榫头25在轴向的一端为榫头25 远离本体21的一端，榫头25在轴向的另一端靠近榫头25与本体21连接的一端；榫头25从一端到轴向上的另一端，横截面积减小；结合图11所示，凹槽11在轴向的一端为凹槽11靠近本体21的开口端16，凹槽11在轴向的另一端为凹槽11远离本体21的抵接端17；凹槽11从开口端16到轴向上的抵接端17，垂直于轴向的横截面的面积增大。也就是说，凹槽11在轴向的开口端16的横截面积较小，在轴向上的抵接端17的横截面积较大，从而当榫头25与波轮1上开设的凹槽11连接成榫卯结构31的连接时，即榫头25沿第一方向斜向滑入凹槽11内与凹槽11配合后，榫头25不易沿轴向移动而脱离，具体在于，当榫头25沿轴向凹槽11开口端16的方向移动时，由于凹槽11的横截面积随靠近开口端16逐渐变小，从而凹槽11对榫头25横截面积相对更大的部分造成了轴向移动限制，从而榫头25无法沿轴向移动并限定在凹槽11内。
本申请实施例的榫头从远离本体的一端到轴向上的另一端，横截面积减小，对应的，波轮上开设的凹槽在轴向上从靠近搅拌棒的一端到远离搅拌棒的另一端，横截面积增大，从而当榫头沿轴向向凹槽开口端移动时，由于凹槽的横截面积随靠近开口端逐渐变小，从而凹槽对榫头横截面积相对更大的部分造成了轴向移动限制，从而榫头无法沿轴向移动并限定在凹槽内，从而在轴向上对搅拌棒和波轮进行了限制。
在一些实施例中，如图10至图12所示，第一伸缩杆23包括把手231和杆体232。其中，把手231沿轴向突出于本体21的第二端29设置，第二端29是指本体21沿轴向远离波轮1的一端；杆体232位于空腔22内，与把手231同轴设置且在空腔22和第二通孔262内运动，杆体232远离把手231的一端形成搅拌棒2的定位结构4；其中，把手231设置卡扣结构6以与本体21可拆卸地连接。例如，卡扣结构6可以是卡槽和卡扣配合的结构。在把手231与本体21的卡扣结构6连接时，此时杆体232部分突出于榫头25，并插入定位孔15内，此时可限定波轮1与搅拌棒2的榫卯结构31在连接状态下的位置；而在需要拆卸波轮和搅拌棒时，则将把手231与本体21的卡扣结构6拆卸，向上提拉把手231，杆体232向上缩回或空腔22内，此时波轮1与搅拌棒2不受定位结构4 的限制，再将波轮1与搅拌棒2的榫卯结构31沿第一方向运动以脱离连接即可。
本申请实施例的第一伸缩杆包括把手和杆体，把手沿轴向突出于本体，且把手的尺寸较大，大致为圆盘状，便于用户手持来回拉动；另外，通过卡扣结构连接把手和本体，使其容易拆装，不仅结构简单，便于加工，且连接也比较紧固。
在一些实施例中，如图10和图11所示，波轮1包括底板12和连接凸块14。其中，底板12沿周向设置有多个旋叶13，且多个旋叶13沿周向均匀设置，在波轮1旋转时，多个旋叶13增加了衣物与波轮1之间的摩擦力，从而衣物与波轮1进行摩擦而去污清洗。连接凸块14位于波轮1的中心位置，连接凸块14用于与搅拌棒2可拆卸地连接，多个旋叶13绕连接凸块14设置；其中，连接凸块14的顶端开设沿第一方向贯穿连接凸块14的凹槽11，凹槽11的壁面可与榫头25壁面抵接，那么榫头25沿第一方向斜向滑入凹槽11内与凹槽11配合后，搅拌棒2和波轮1在榫卯结构31的连接下，也难以沿周向旋转运动，从而搅拌棒2和波轮1只能沿第一方向运动。连接凸块14上设置位于凹槽11底部的沿轴向延伸的定位结构4，即定位孔15，第一伸缩杆23突出于榫头25的部分可沿轴向插入定位孔15内，从而对榫卯结构31的连接状态进行定位。
本申请实施例的波轮包括底板和连接凸块，多个旋叶增加了衣物与波轮之间的摩擦力，从而衣物与波轮进行摩擦而去污清洗；连接凸块开设贯穿第一方向的凹槽，凹槽的壁面可与榫头壁面抵接，从而限定榫头相对于波轮的周向旋转；并且榫头在轴向上的移动也受到自身的限制，连接凸块上设置位于凹槽底部的沿轴向延伸的定位孔，当第一伸缩杆插入定位孔后，可限制榫头相对于凹槽沿第一方向的移动，从而搅拌棒和波轮在周向，轴向，径向均受到限制，且衣服与搅拌棒之间在水中进行摩擦，导致搅拌棒受到的较大的旋转阻力由榫卯结构承担，而榫卯结构具有足够的结构强度，使得波轮和搅拌棒的连接更加稳固，并且实际上搅拌棒受到的沿第一方向的阻力是较小的，因此定位结构足以支撑搅拌棒和波轮的连接。
在一些实施例中，如图15和图16所示，波轮1还包括榫卯销5，榫卯销5 可填充凹槽11并与连接凸块14可拆卸地连接。榫卯销5包括类似于榫头的结构，榫卯销5允许自身与波轮1之间的沿第一方向的相对运动以连接和脱离连接，且榫卯销5还限定自身与波轮1在连接状态下的位置。榫卯销5的长度远小于搅拌棒2的长度，基本上是只具有填充凹槽11的作用，而不具有搅拌的作用。本申请实施例的波轮还包括榫卯销，榫卯销可填充凹槽并与连接凸块可拆卸地连接，从而当搅拌棒拆除后波轮上产生的空隙可由榫卯销可拆除式插入，以防止空隙处缠绕衣物。
在一些实施例中，如图17和图18所示，榫卯销5包括销主体51和第二伸缩杆52。销主体51的外形类似于榫头的结构，即从远离波轮1的第三端54到轴向上靠近波轮1的第四端55，销主体51具有横截面积增大的一段。在正常放置时，销主体51具有横截面积从上往下增大的一段，从而当榫卯销5沿轴向向凹槽11的开口端16移动时，即沿轴向向上提拉时，由于凹槽11的横截面积从下往上逐渐减小，销主体51的尺寸与凹槽11的尺寸刚好配合，且销主体51下方的横截面积较大的部分难以向上移动至凹槽11上方的横截面积较小的部分，销主体51只能沿第一方向滑出凹槽11，从而榫卯销5无法沿轴向移动并限定在凹槽11内。其中，销主体51内部开设贯穿轴向的通道56，销主体51可与凹槽11的壁面抵接，从而限定销主体51相对于波轮1的周向旋转，使得销主体51相对于波轮1稳定沿第一方向移动。
如图17和图18所示，第二伸缩杆52可贯穿通道56并沿通道56运动，以突出销主体51并和凹槽11底部的定位结构4连接，和缩回通道56并和定位结构4脱离连接。第二伸缩杆52与销主体51也可通过卡扣结构6实现可拆卸地连接。在第二伸缩杆52与销主体51连接时，此时第二伸缩杆52突出于销主体51的部分可插入定位孔15内，此时可限定波轮1与榫卯销5在连接状态下的位置；而在需要拆卸波轮1和榫卯销5时，则将第二伸缩杆52与销主体51拆卸，向上提拉第二伸缩杆52，第二伸缩杆52向上缩回通道56内，此时波轮1与榫卯销5不受定位结构4的限制，再将波轮1与榫卯销5沿第一方向运动以脱离连接即可。
如图1-2和图9-10所示，本申请实施例还提供一种衣物处理设备，例如，衣物处理设备可以是搅拌式洗衣机等。衣物处理设备包括桶体和波轮组件10。其中，桶体具有用于容纳衣物的容纳腔；波轮组件10位于容纳腔内且波轮1连接在桶体的底部。衣物处理设备在脱水的时候，波轮1和桶体都旋转；在洗涤的时候，波轮1旋转，桶体不旋转，波轮1带动搅拌棒2一起旋转，从而带动机身内水流及衣服运动；运动中的水流推动衣服不停地翻转，使衣服之间、衣服与桶壁及搅拌棒之间，在水中进行摩擦，并在洗涤剂的作用下实现去污清洗。
本申请实施例的衣物处理设备包括桶体和波轮组件，波轮连接在桶体的底部，在洗涤衣物时，波轮正反旋转并带动搅拌棒一起旋转，从而带动机身内水流及衣服运动；运动中的水流推动衣服不停地翻转，使衣服之间、衣服与桶体的内壁面及搅拌棒之间，在水中进行摩擦，并在洗涤剂的作用下实现去污清洗。在波轮正反旋转并带动搅拌棒一起旋转时，由于衣服与搅拌棒之间在水中进行摩擦，导致搅拌棒受到较大的旋转阻力，从而用于对波轮和搅拌棒限位的结构需要承担较大的旋转阻力，本申请实施例的波轮和搅拌棒的连接稳固，从而波轮在带动搅拌棒一起旋转时，用于对波轮和搅拌棒限位的结构不易断裂，从而搅拌棒和波轮可以稳定限位并一起旋转。
以上所述，仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。
