具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明的技术方案可以采用不同结构的锁扣件对波轮10在转轴20轴向上的锁固。如图7至9所示，在本发明的一最佳实施例中，上述波轮连接组件包括花键30和锁扣件，其中所述波轮10通过花键与所述转轴20联接，所述锁扣件与所述转轴20卡合固定连接，且与所述波轮10固定连接，以限制所述波轮10在转轴20的轴向移动。
具体地，在本实施例中，上述锁扣件包括波轮锁套45、波轮锁盖46和锁芯47；其中所述波轮锁套45与所述波轮10固定连接，所述波轮锁盖46与所述波轮锁套45卡合固定连接，所述锁芯47与所述波轮锁盖46卡合固定连接；所述波轮锁盖46具有一容置腔，所述转轴20的一端穿过所述波轮10和波轮锁套45位于所述容置腔内，且与所述锁芯47卡合固定连接。
上述锁芯47包括把手部471以及由把手部471向同一侧延伸的两弹性卡扣472和两夹持臂473，所述两弹性卡扣472位于两夹持臂473的外侧；所述波轮锁盖46上设有供所述锁芯47插入所述容置腔的插孔以及位于所述插孔两侧且与所述两弹性卡扣472适配的固定孔；所述转轴20上设有呈环形设置的第三凹槽24，所述两夹持臂473位于所述第三凹槽24内，且夹持固定所述转轴20。
在本实施例中，波轮锁盖46朝向波轮锁套45的一侧设有卡爪以及定位柱，波轮锁套45对应卡爪的位置设有方形孔，对应定位柱的位置设有定位孔。安装时，可以首先将波轮锁盖46通过卡爪和定位柱配合安装形成一个整体，然后将这个整体通过螺钉固定的方式安装固定在波轮10上。最后将锁芯47通过插孔插入到容置腔中，并由两夹持臂夹持在第三凹槽24内，直至两弹性卡扣472卡合固定在对应的固定孔内，以限制波轮10在转轴20的轴向运动。
本发明提供一种洗衣机，参照图1至图6，在其他一实施例中，所述洗衣机包括波轮10、减速离合器和波轮连接组件，所述减速离合器具有转轴20，所述波轮连接组件与所述转轴20卡合固定连接，以将所述波轮10与转轴20可拆卸固定连接。
本发明实施例通过设置波轮连接组件，由波轮连接组件与转轴卡合固定连接，以实现波轮10与转轴20可拆卸固定连接。从而相对于现有技术中采用螺钉的方式进行固定，可以有效降低波轮10的拆卸难度，从而减小洗衣机拆装时对零部件的损坏，延长了洗衣机的使用寿命。
可以理解的是，上述波轮连接组件的结构可以根据实际需要进行设置，例如，在一实施例中，该波轮连接组件将波轮10与转轴20可拆卸固定连接，所述波轮连接组件包括花键30和锁扣件，其中所述波轮10通过花键30与所述转轴20联接，所述锁扣件与所述转轴20可拆卸固定连接，且与所述波轮10抵接，以限制所述波轮10在转轴20的轴向移动。
上述波轮连接组件主要应用于波轮洗衣机中，以实现波轮10和转轴20的固定。本实施例中，上述转轴20为用于控制波轮10转动的减速离合器转轴。具体地，可以在波轮10上表面的中心位置设有一容置空间，用于安装并收容锁扣件，且容置空间的侧壁与锁扣件的外壁之间存在间隙，以供用户进行拆卸使用。
本发明通过采用花键30将波轮10与所述转轴20联接，以限制波轮10与转轴20之间的相对转动，同时通过锁扣件与所述转轴20可卡合固定连接，以限制所述波轮10在转轴20的轴向移动；由于采用卡合固定的方式对波轮10固定，相对于现有技术中采用螺钉的方式进行固定，可以有效降低波轮10的拆卸难度，从而减小洗衣机拆装时对零部件的损坏，延长了洗衣机的使用寿命。
可以理解的是，上述锁扣件的结构可以根据实际需要进行设置，本实施例中，优选地，上述锁扣件包括锁扣套件41、锁扣主体42、锁压弹簧43和卡簧圈44；所述锁扣套件41设有收容所述锁扣主体42的通孔412，所述通孔412的底端凸设有限位台阶411；所述锁扣主体42在所述通孔412内可沿通孔412的轴向移动，且所述锁扣主体42的底端向内凹陷形成用于收容所述转轴20的收容腔421；所述锁压弹簧43的顶端与所述锁扣主体42抵接，底端与所述限位台阶411抵接；所述卡簧圈44与锁扣主体42的外壁可拆卸固定连接，且位于所述限位台阶411下方，与所述限位台阶411抵接，以限制所述锁扣主体42在所述通孔412内沿通孔412的轴向移动的距离；所述锁扣主体42外壁对应所述限位台阶411的位置设有贯穿所述收容腔421的限位孔423，所述限位孔423内设有限位凸块422，所述限位凸块422与所述转轴20上预设的限位槽21相互抵持卡合。
具体地，上述锁扣主体42的外壁设有与所述卡簧圈44适配的卡槽424；所述卡簧圈44位于所述卡槽424内，且与所述锁扣主体42卡合固定连接。上述限位台阶411的形状可以根据实际需要进行设置，优选地，该限位台阶411为环形台阶。具体地，该环形台阶的内径小于卡簧圈44的外径，以使得锁扣主体42在锁压弹簧43作用力向上运动时，卡簧圈44可以与限位台阶411抵持，以限制锁扣主体42继续向上运动。可以理解的是，锁扣主体42用于抵接锁压弹簧43的结构可以根据实际需要进行设置，本实施例中，优选地，可以由锁扣主体42顶端的外壁向外延伸形成一环形台阶进行抵接。
进一步地，上述限位孔423和限位凸块422的结构均可根据实际需要进行设置，本实施例中，优选地，上述限位孔423为锥形孔，且锥形孔与收容腔421连通的一端内径小于另一端的内径；所述限位凸块422为球体。具体地，该限位凸块422的数量和位置可以根据实际需要进行设置，优选地，为了保证平衡稳定性，上述限位凸块422至少为4个，且均匀设置于所述锁扣主体42的同一圆周上。为了方便安装，上述限位槽21优选为环形凹槽。
安装时，首先波轮10通过花键30与转轴20联接；接着将限位凸块422分别装入对应的限位孔423内，然后在锁扣主体42的外圈上套上锁压弹簧43后，插入到锁扣套件41的通孔412中，使得锁压弹簧43与锁扣套件41的限位台阶411抵接；继续施加向下的作用力，使得弹簧产生形变，以使锁扣主体42底部穿出通孔412，接着在锁扣主体42的卡槽424内安装固定卡簧圈44，从而形成锁扣件。
再接着将锁扣件置于波轮10上，使得锁扣主体42的收容腔421部分收容转轴20；然后施加外力将锁扣主体42下压，让锁扣主体42沿锁压弹簧43的收缩方向发生相对运动，并使得限位台阶411与限位凸块422错位，同时限位凸块422向锁扣主体42和锁扣套件41之间的间隙运动，为转轴20提供避让位。当限位凸块422正对转轴20上的限位槽21时，限位凸块422向限位槽21内滑动，此时撤去外力，锁扣件将恢复自然状态；限位凸块422的一端与限位槽21抵持，另一端将与限位台阶411抵接，从而实现锁扣件与转轴20卡合；在锁压弹簧43的作用力下锁扣套件41将抵持压紧波轮10，以限制波轮在转轴20的轴向运动。
在拆卸时，仅需要将锁扣套件41上提，使得限位台阶411与限位凸块422错位，让限位台阶411具有避让空间，然后向上提起锁扣件即可。
进一步地，基于上述实施例，本实施例中，上述波轮连接组件还包括保护盖50和盖压弹簧60，所述保护盖50上设有收容所述锁扣件的收容孔53；所述保护盖50的底面设有若干卡扣51，所述卡扣51与波轮上预设的卡孔12相互卡合；所述盖压弹簧60的一端与所述保护盖50的底面抵接，另一端与所述波轮10抵接。
本实施例中，为了方便盖压弹簧60的安装，上述波轮10上设有用于收容所述盖压弹簧60的第一凹槽11，所述盖压弹簧60与所述波轮10抵接的一端位于所述第一凹槽11内。此外，上述保护盖50的底面还设有加强筋52，所述加强筋52与所述波轮10上预设的导向孔13配合，以对所述保护盖50沿所述收容孔53的轴向运行进行导向。
具体地，安装时，首先将盖压弹簧60置于第一凹槽11内，并通过作用力下压保护盖50，使得卡扣51穿过卡孔12，同时加强筋52穿过导向孔13，释放压力后，通过盖压弹簧60与卡扣51配合将保护盖50固定。此时保护盖50的上表面与锁扣套件41的上表面平齐。在保护盖50上下压即可为锁扣套件41的安装和拆卸腾出手指的操作空间；优选地，加强筋52和收容孔53形成的收容空间呈倒置的凸台结构，并当保护盖50上升到最高位置时（即保护盖50的上表面与锁扣套件41的上表面平齐时），加强筋52和收容孔53形成的收容空间与锁扣套件41的倒置凸台外形相契合，以限制保护盖50脱离。
可以理解的是，上述卡扣51和加强筋52的数量可根据实际需要进行设置，本实施例中为了保证保护盖固定的稳定性，优选地，卡扣51和加强筋52均为四条，且四条卡扣51均匀分布在靠近保护盖50外侧的同一圆周上，四条加强筋52均匀分布在靠近保护盖50内侧的同一圆周上。
参照图10至图14，在另一实施例中，上述波轮连接组件还可以采用其他结构，以下对此进行详细说明。
优选地，在本实施例中上述波轮连接组件为波轮锁扣。在本实施例中提供的洗衣机包括波轮锁扣70、波轮10和减速离合器。减速离合器的中部有竖直设置的转轴20，波轮10安装在转轴20的上部，波轮10包括安装通孔80，转轴20的顶端从安装通孔80中伸出，波轮锁扣70设有安装槽78以及卡扣部73，所述卡扣部73突伸出所述安装槽78的内壁而延伸入所述安装槽78中，转轴20上设置有与卡扣部73配合的卡扣配合部22，卡扣部73与卡扣配合部22配合将波轮10紧固在转轴20上。在本实施例中，所述卡扣配合部22优选为呈环形设置的第二凹槽。
本发明的洗衣机通过波轮锁扣70将波轮10紧固在减速离合器的顶端，无需借助外界工具、通过简单的手部动作就可以实现波轮10的快速安装和拆卸，使得波轮10的拆卸和安装变得方便快捷，且在拆卸安装过程中对零件损伤较小，利于波轮等零部件的清洁。
本实施例的波轮锁扣70的具体结构为：如图12所示，包括中空圆柱状的锁主体71、锁套件72、弹性件75、轴向限位件76和卡扣部73，锁主体71的中空部形成安装槽78，其中卡扣部73优选为四个钢球，其刚性好且不易磨损；弹性件75优选为压簧，在其他的实施例中也可以选用其他回弹性好的弹性件；轴向限位件76优选为卡簧；压簧75和锁套件72均为空心圆柱体，锁主体71包括空心圆柱状的主体712和在主体712的顶端形成的圆柱状的密封部713，密封部713的半径大于主体712的外半径；锁套件72通过卡簧76套装在锁主体71的外部，所述锁套件72自锁主体71底端内侧向内延伸设有突起部721，卡簧76卡扣在突起部721的底部，压簧75置于锁主体71和锁套件72之间并套在锁主体71上，密封部713位于锁套件72内且压扣在压簧75的顶部；锁主体71的下端沿在圆周上设有四个沿径向延伸、贯通锁主体71的外部和安装槽78的通道的圆台状通道711，其靠近安装槽78处的孔径小于远离安装槽78处的孔径，四个圆台状通道711均匀地分布在锁主体71的圆周上，四个钢球73分别放置在四个圆台状通道711内并可以在其内移动；锁套件72的底端内侧对应于圆台状通道711的位置设有四个突起部721，用于顶紧四个钢球73，压簧75的底部与突起部721的顶部接触；当施加外力时，锁主体71与锁套件72可以沿压簧75压缩的方向相对运动，锁套件72的突起部721与钢球73的位置错位，锁主体71与锁套件72之间在钢球73的位置处留出了一定的空隙，钢球73在波轮锁扣70的圆台状通道711可以径向移动。
进一步地，如图13所示，转轴20上部沿轴向设置有第一花键23，安装通孔80内壁设置有与第一花键23配合的第二花键81。波轮10通过第一花键23和第二花键81的配合安装在转轴20上。
具体地，在安装波轮锁扣70时，一手按压锁主体71，另一只手将锁套件72往向上的方向提拉，锁套件72相对于锁主体71向上运动，锁套件72的内侧突起部721与钢球73所在位置发生错位，锁主体71与锁套件72之间在钢球73的位置处留出了一定的空间，钢球73在圆台形通道内向远离锁扣本体11的方向移动。将波轮锁扣70套装在转轴20的顶端，使卡扣部73伸出卡扣在第二凹槽22内，当波轮锁扣70的钢球73与减速离合器的转轴20的第二凹槽22对齐时，钢球73从圆台状通道711内露出的部分卡扣在第二凹槽22内；此时，撤去外力作用，波轮锁扣70的钢球73与减速离合器的转轴20的第二凹槽22配合并被锁套件72内侧的突起部721顶紧，实现波轮锁扣70与减速离合器的转轴20的配合联接。
在拆卸波轮10时，用手将锁套件72往向上的方向提拉，锁套件72相对于锁主体71向上运动，锁套件72的内侧突起部721与钢球73所在位置发生错位，钢球73被减速离合器的转轴20挤入锁套件72与锁主体71之间的缝隙内，整个波轮锁扣70从减速离合器的转轴20上方脱离，这样就可以很容易的将波轮10从减速离合器的转轴20上拆卸下来，无需任何额外的辅助工具，使得波轮10的拆卸和安装变得方便快捷，且在拆卸过程中对零件损伤较小，利于波轮等零部件的清洁。
本发明提出的洗衣机，其波轮10通过花键的方式联接到减速离合器的转轴20上，然后再通过一个波轮锁扣70与减速离合器转轴20的连接配合将波轮10紧固到减速离合器的转轴20上，使得波轮10的拆卸和安装变得方便快捷，且拆卸安装过程中对零件损伤较小，利于波轮10的清洁，延长了洗衣机的整机使用寿命。
需要说明的是，本实施例中的波轮锁扣70和波轮10为分开的装置，在其他的实施例中，波轮锁扣70可以固定地设置在波轮10上，锁套件72与波轮10固定连接，对锁套件72施加外力时，可使波轮10从减速离合器上弹出，方便波轮10的安装和拆卸。
可以理解的是，上述波轮的材质可以根据实际需要进行设置，本实施例中，优选地，上述波轮10由不锈钢材料制成的。由于采用金属结构制成波轮，从而在结构上有相当强的硬度，其底面没有塑料波轮那样为加强强度而起的一系列的筋，进而波轮连接组件和波轮的搭配使用使得清洗更加方便，造型简洁美观。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
