本公开要求无锡小天鹅股份有限公司于2018年02月07日提交的、中国专利申请号“201810122495.3”和“201820221165.5”的优先权。
技术领域
本公开涉及衣物处理装置技术领域，更具体地，涉及一种用于滚筒洗衣机的行星齿轮部装以及滚筒洗衣机。
背景技术
滚筒洗衣机在洗涤衣物时，内筒转动带动衣物和内筒内的水转动洗涤衣物，其中依靠内筒内的挡板将衣物举起和放下且通过内筒的内周面摔打衣物。然而，由于其洗涤方式单一，影响了洗涤效果。因此，存在改进的需求。
为此，相关技术中提出了在内筒内设置波轮的滚筒洗衣机，例如PCT/CN2016/11037公开了一种滚筒式洗衣机，通过电机直接驱动波轮旋转，同时电机通过行星齿轮机构的传动带动内筒旋转，使得内筒的旋转速度低于波轮的旋转速度。然而，由于内筒本身相较于波轮体积较大，且洗涤时内筒需要承载衣物和水，导致行星齿轮机构的负载较大，进而影响行星齿轮机构对动力的传递效果以及自身的使用寿命。
发明内容
本公开旨在至少解决现有技术中存在的技术问题之一。为此，本公开提出一种用于滚筒洗衣机的行星齿轮部装，所述行星齿轮部装能够将主轴的转矩传递至搅拌器，从而实现对内筒和搅拌器的双驱动，且具有动力传递稳定、使用寿命长等优点。

下面参考图1-图23描述根据本公开实施例的用于滚筒洗衣机的行星齿轮部装。
如图1-图23所示，根据本公开实施例的用于滚筒洗衣机的行星齿轮部装6包括：行星齿轮组件61。
行星齿轮组件61包括行星轮架611、多个行星齿轮612和行星轮外齿壳613。多个行星齿轮612分别可旋转地安装于行星轮架611，多个行星齿轮612适于分别与滚筒洗衣机中用于驱动内筒2旋转的主轴31啮合，行星轮外齿壳613套装于多个行星齿轮612外侧且与多个行星齿轮612分别啮合，行星轮外齿壳613适于与内筒2内的搅拌器4 传动连接。
根据本公开实施例的用于滚筒洗衣机的行星齿轮部装6，通过在主轴31与搅拌器4之间设置行星齿轮部装6，能够将主轴31的转矩传递至搅拌器4以驱动搅拌器4旋转，由此，搅拌器4的旋转与内筒2的旋转可以彼此组合成多种的洗涤方式，例如搅拌器4和内筒2中的任一个单独旋转或搅拌器4和内筒2同时旋转，再例如搅拌器4和内筒2同向旋转或反向旋转，从而使滚筒洗衣机100的洗涤方式多样化。
并且，利用行星齿轮部装6将主轴31的转矩传递至搅拌器，可以利用驱动器间接驱动搅拌器4，由于搅拌器4处的负载远远小于内筒2处的负载，因此相比相关技术中具有波轮(搅拌器)的滚筒洗衣机，作用于行星齿轮部装6的载荷得到了极大的减小，不仅利于动力的稳定传递以提高滚筒洗衣机100的性能稳定性，而且大幅降低了行星齿轮部装6损坏的风险，有利于延长滚筒洗衣机100的使用寿命。
根据本公开的一个实施例，行星轮架611被允许自由旋转时，多个行星齿轮612将主轴31的转矩同向传递至行星齿轮外齿壳613。行星轮架611被制动时，多个行星齿轮612将主轴31的转矩反向传递至行星齿轮外齿壳613。
举例而言，当滚筒洗衣机100处于脱水模式时，可以将行星轮架611切换至允许自由旋转，从而通过行星齿轮外齿壳613带动搅拌器4与内筒2同向旋转，保证衣服在高速旋转脱水时不会发生缠绕、被撕损等情况。
而当滚筒洗衣机100处于洗涤模式时，可以制动行星轮架611，通过行星齿轮外齿壳613带动搅拌器4与内筒2反向旋转，从而充分搅拌衣服和水，提高衣服洗涤时的洗净效果。
本领域的技术人员可以理解地是，行星齿轮部装6的行星轮架611状态切换与滚筒洗衣机100当前所处模式的结合，不局限于上述实施例，也可以在脱水和洗涤模式中的任一个内，同时结合行星轮架611的自由旋转状态和制动状态。
在一些示例中，行星轮架611被制动时，行星齿轮外齿壳613的转速小于主轴31的转速。也就是说，行星轮架611被制动时，实现对动力的变减速传递。由此在充分搅拌衣服和水时，避免衣服缠绕，且利于整机的稳定性和噪音。
在一些示例中，行星轮架611被允许自由旋转时，行星齿轮外齿壳613的转速等于主轴31的转速。即行星轮架611被允许自由旋转时，搅拌器4与内筒2同步(同速且同向)旋转。
参照图8至图10，行星轮架611包括：行星轮支架6111和行星轮固定盘6116。多个行星齿轮612分别可旋转地安装于行星轮支架6111的一侧面，行星轮支架6111的一侧面设有多个安装凸台6112，行星轮固定盘6116安装于多个安装凸台6112，方便 行星轮支架6111与行星轮固定盘6116的连接。
在一些示例中，行星轮支架6111和行星轮固定盘6116均位于行星轮外齿壳613内，行星轮支架6111和行星轮固定盘6116分别止挡在行星轮外齿壳613的内齿的两侧，从而依靠行星轮外齿壳613的内齿齿端、在行星轮外齿壳613的轴向上进行定位。行星轮支架6111可以对多个行星齿轮612进行定位安装，行星轮支架6111与行星轮固定盘6116的组合结构可以将多个行星轮限定在行星轮支架6111与行星轮固定盘6116之间，实现结构的模块化组装，使结构更紧凑，组装更方便。
在一些示例中，行星轮固定盘6116设在行星轮外齿壳613内，并通过紧固件固装在行星轮支架6111上，连接可靠。
在一些示例中，行星轮支架6111的一侧面设有多个行星轮安装座6114，每个行星轮安装座6114上设有行星轮固定轴6115，多个行星齿轮612分别可旋转且一一对应地安装于多个行星轮固定轴6115。这里的“一一对应”可以理解为行星齿轮612的数量与行星轮安装座6114的数量相等，每个行星轮安装座6114设有一个行星齿轮612。
在一些具体示例中，行星轮安装座6114上设有插孔，行星轮固定轴6115的一端插接在行星轮安装座6114的插孔内，而行星轮固定轴6115的另一端置于行星轮固定盘6116的限位孔6118中从而对行星齿轮612进行定位安装。
在一些示例中，行星轮支架6111的一侧面设有多个安装凸台6112和多个行星轮安装座6114，多个安装凸台6112和多个行星轮安装座6114沿行星轮支架6111的周向交替设置，从而使多个安装凸台6112和多个行星齿轮612沿行星轮支架6111的周向交替设置。
进一步地，每个安装凸台6112上设有定位柱6113，行星轮固定盘6116上设有多个定位孔6117，多个安装凸台6112上的定位柱6113一一对应地紧配合或焊接在多个定位孔6117内，使得行星轮固定盘6116支撑在多个安装凸台6112上，从而实现行星轮固定盘6116与行星轮支架6111的组装，连接方便。
如图7、图8以及图11所示，根据本公开进一步的实施例，行星齿轮部装6还包括：行星轮外壳62，行星齿轮组件61设于行星轮外壳62内，从而实现行星齿轮部装6的模块化设计。行星轮外齿壳613通过行星轮外壳62与搅拌器4传动连接，例如，行星轮外壳62与搅拌器4可以通过螺钉进行组合，行星轮外齿壳613、行星轮外壳62和搅拌器4固定连接，以实现同步运行，便于通过行星齿轮部装6将主轴31的转矩传递至搅拌器4。
在一些示例中，行星轮外壳62的内周壁和行星轮外齿壳613的外周壁中的一个上设有凸缘6131，行星轮外壳62的内周壁和行星轮外齿壳613的外周壁中的另一个上设 有卡槽621，凸缘6131配合在卡槽621内，保证行星轮外壳62与行星轮外齿壳613的固定连接。
在一些可选的示例中，行星轮外齿壳613的外周壁设有多个凸缘6131，每个凸缘6131沿行星轮外齿壳613的轴向延伸，多个凸缘6131沿行星轮外齿壳613的周向间隔设置。
对应地，行星轮外壳62的内周壁设有多个卡槽621，每个卡槽621沿行星轮外壳62的轴向延伸，多个卡槽621沿行星轮外壳62的周向间隔设置，多个凸缘6131一一对应地配合在多个卡槽621内，既可以实现行星轮外齿壳613与行星轮外壳62的连接，又可以保证行星轮外齿壳613与行星轮外壳62的周向定位，实现行星轮外齿壳613与行星轮外壳62的同步运行。
可以理解的是，多个凸缘6131与多个卡槽621的设置位置可互换，例如，多个凸缘6131均设在行星轮外壳62的内周壁，而多个卡槽621均设在行星轮外齿壳613的外周壁，还可以为多个凸缘6131中的一部分设在行星轮外齿壳613的外周壁上，另一部分设在行星轮外壳62的内周壁上，而多个卡槽621的也对应分别设在行星轮外齿壳613的外周壁和行星轮外壳62的内周壁，连接方便。
如图7所示，并结合图1、图21和图23，根据本公开更进一步的实施例，行星齿轮部装6还包括：行星轮轴承63，行星轮轴承63设于行星轮外壳62内且位于行星齿轮组件61的外侧，行星轮轴承63的内圈套设于主轴31且随主轴31旋转，行星轮轴承63的外圈与行星轮外壳62相连且随行星轮外壳62旋转，通过设置行星轮轴承63，可以保证行星轮外壳62相对于主轴31旋转。
可选地，行星轮架611的内周面设有适于与主轴31内的第二轴32啮合的啮合齿。由此，行星轮架611固定安装在第二轴32上，实现与第二轴32同步旋转。
在一些可选的示例中，第二轴32由套设在其上且设于空腔311内的第二轴轴承3211支撑。具体地，主轴31的空腔311内设有至少两个第二轴轴承3211，第二轴32穿过至少两个第二轴轴承3211以支撑在主轴31的空腔311内且相对于主轴31可旋转。
在一些示例中，行星齿轮部装6还包括第二轴端轴承3212，行星轮外壳62设有通孔622，第二轴32穿设于通孔622，第二轴32由套设在其上且设于通孔622内的第二轴端轴承3212支撑。由此，行星轮外壳62的一端通过第二轴端轴承3212支撑在第二轴32上，行星轮外壳62的另一端通过行星轮轴承63支撑在主轴31上，既实现了行星齿轮部装6的定位安装，又可以保证行星轮外壳62相对于第二轴32和主轴31旋转。
在一些示例中，行星齿轮部装6还包括轴密封件325，轴密封件325设于通孔622内且位于第二轴端轴承3212外侧，轴密封件325适于密封第二轴32与行星轮外壳62 之间的缝隙。
具体地，第二轴32上套设有轴密封件325，轴密封件325设置在第二轴32上且位于第二轴端轴承3212的外侧，即轴密封件325相对于第二轴端轴承3212更加远离第二轴32的轴向中心处，轴密封件325密封第二轴32与行星轮外壳62之间的缝隙，防止第二轴32的供水通道320内的水通过第二轴32与行星轮外壳62之间缝隙进入主轴31的空腔311以及行星齿轮部装6中。
根据本公开实施例的滚筒洗衣机100包括根据上述实施例所述的用于滚筒洗衣机的行星齿轮部装6。
由于根据本公开实施例的用于滚筒洗衣机的行星齿轮部装6具有上述技术效果，因此根据本公开实施例的滚筒洗衣机100也具有上述技术效果，即通过在滚筒洗衣机100的主轴31与搅拌器4之间设置行星齿轮部装6，利用行星齿轮部装6将主轴31的转矩传递至搅拌器4以驱动搅拌器4旋转，由此，搅拌器4的旋转与内筒2的旋转可以彼此组合成多种的洗涤方式，从而使滚筒洗衣机100的洗涤方式多样化。
并且，利用行星齿轮部装6将主轴31的转矩传递至搅拌器4，可以利用驱动器间接驱动搅拌器4，由于搅拌器4处的负载远远小于内筒2处的负载，因此相比相关技术中具有波轮的滚筒洗衣机，作用于行星齿轮部装6的载荷得到了极大的减小，不仅利于动力的稳定传递以提高滚筒洗衣机100的性能稳定性，而且大幅降低了行星齿轮部装6损坏的风险，有利于延长滚筒洗衣机100的使用寿命。
下面结合图1-图23，详细描述根据本公开的滚筒洗衣机100的一些具体实施例。
如图1-图23所示，根据本公开实施例的滚筒洗衣机100包括：外桶1、内筒2、搅拌器4、驱动器(如下述的电机5)和行星齿轮部装6。
内筒2可旋转地设于外桶1内。搅拌器4可旋转地设于内筒2内。驱动器通过主轴31与内筒2传动连接，主轴31将驱动器的转矩传递至内筒2。行星齿轮部装6分别与主轴31和搅拌器4传动连接，驱动器驱动主轴31旋转时，行星齿轮部装6可以将主轴31的转矩传递至搅拌器4，从而驱动搅拌器4旋转。
根据本公开实施例的滚筒洗衣机100，通过设置驱动器，利用驱动器通过驱动主轴31旋转以带动内筒2旋转，且进一步在内筒2内设置搅拌器4，并利用行星齿轮部装6将主轴31的转矩传递至搅拌器4以驱动搅拌器4旋转，由此，搅拌器4的旋转与内筒2的旋转可以彼此组合成多种的洗涤方式，例如搅拌器4和内筒2中的任一个单独旋转或搅拌器4和内筒2同时旋转，再例如搅拌器4和内筒2同向旋转或反向旋转，从而使滚筒洗衣机100的洗涤方式多样化。
并且，驱动器通过主轴31驱动内筒2，以利用驱动器直接驱动负载较大的部件， 动力传递的级数更少，动力输送更加直接，从而稳定驱动体积较大且需容纳衣物和水的内筒，而在主轴31与搅拌器4之间设置行星齿轮部装6，利用行星齿轮部装6将主轴31的转矩传递至搅拌器，以利用驱动器间接驱动搅拌器4，由于搅拌器4处的负载远远小于内筒2处的负载，因此相比相关技术中具有波轮的滚筒洗衣机，作用于行星齿轮部装6的载荷得到了极大的减小，不仅利于动力的稳定传递以提高滚筒洗衣机100的性能稳定性，而且大幅降低了行星齿轮部装6损坏的风险，以延长滚筒洗衣机100的使用寿命。
因此，根据本公开实施例的滚筒洗衣机100能够实现多样化洗涤方式，且具有性能稳定、使用寿命长等优点。
根据本公开的一个实施例的滚筒洗衣机100，行星齿轮部装6在第一状态和第二状态之间可切换。
行星齿轮部装6处于第一状态时，行星齿轮部装6将主轴31的转矩同向传递至搅拌器4，从而使搅拌器4与内筒2同向旋转。行星齿轮部装6处于第二状态时，行星齿轮部装6将主轴31的转矩反向传递至搅拌器4，从而使搅拌器4与内筒2反向旋转。例如，若驱动器驱动主轴31顺时针旋转，当行星齿轮部装6处于所述第一状态时，行星齿轮部装6将主轴31的转矩同向传递至搅拌器4，从而使搅拌器4与内筒2均顺时针旋转。当行星齿轮部装6处于第二状态时，行星齿轮部装6将主轴31的转矩反向传递至搅拌器4，从而使搅拌器4逆时针旋转。
举例而言，当滚筒洗衣机100处于脱水模式时，可以将行星齿轮部装6切换至第一状态，通过行星齿轮部装6在第一状态的动力传递方式带动搅拌器4与内筒2同向旋转，保证衣服在高速旋转脱水时不会发生缠绕、被撕损等情况。
而当滚筒洗衣机100处于洗涤模式时，可以将行星齿轮部装6切换至第二状态，通过行星齿轮部装6在第二状态的动力传递方式带动搅拌器4与内筒2反向旋转，从而充分搅拌衣服和水，提高衣服洗涤时的洗净效果。
本领域的技术人员可以理解地是，行星齿轮部装6的状态切换与滚筒洗衣机100当前所处模式的结合，不局限于上述实施例，也可以在脱水和洗涤模式中的任一个内，同时结合行星齿轮部装6的第一状态和第二状态。
由此，通过设置可在第一状态和第二状态之间切换的行星齿轮部装6，可以调整搅拌器4的旋转方向，使搅拌器4与内筒2同向和反向旋转，从而配合内筒2组成适于不同工况的工作模式。
在一些示例中，搅拌器4与内筒2反向旋转时，搅拌器4的转速小于内筒2的转速。也就是说，行星齿轮部装6处于第二状态时，实现对动力的变减速传递。由此在充分 搅拌衣服和水时，避免衣服缠绕，且利于整机的稳定性和噪音。
在一些示例中，搅拌器4与内筒2同向旋转时，搅拌器4的转速等于内筒2的转速。即行星齿轮部装6处于第一状态时，搅拌器4与内筒2同步(同速且同向)旋转。
如图6-图11所示，根据本公开的一个实施例，行星齿轮部装6包括行星齿轮组件61且行星齿轮组件61包括：行星轮架611、多个行星齿轮612和行星轮外齿壳613。
多个行星齿轮612分别可旋转地安装于行星轮架611，主轴31的外侧周壁具有啮合齿，多个行星齿轮612分别与主轴31上的啮合齿啮合。行星轮外齿壳613套装于多个行星齿轮612外侧，并且行星轮外齿壳613与多个行星齿轮612分别啮合，行星轮外齿壳613与搅拌器4传动连接。
可以理解的是，行星轮外齿壳613的内侧周壁具有与多个行星齿轮612啮合的啮合齿。由此，主轴31、多个行星齿轮612、行星轮架611以及行星轮外齿壳613构成了行星轮系，主轴31的与多个行星齿轮612啮合的轴段形成行星轮系的太阳齿轮。
其中，行星轮架611被允许自由旋转时行星齿轮部装6处于第一状态，从而使搅拌器4与内筒2同向旋转；行星轮架611被制动时行星齿轮部装6处于第二状态，多个行星齿轮612分别自转，行星轮外齿壳613与主轴31反向旋转，从而使搅拌器4与内筒2反向旋转。由此，可以通过切换行星齿轮部装6的行星轮架611的状态，控制搅拌器4的运行状态，实现滚筒洗衣机100的多种工作模式的切换。
由此，根据本公开实施例的滚筒洗衣机100，通过在主轴31与搅拌器4之间设置行星齿轮部装6，利用行星齿轮部装6将主轴31的转矩传递至搅拌器4以驱动搅拌器4旋转，由此，搅拌器4的旋转与内筒2的旋转可以彼此组合成多种的洗涤方式，例如搅拌器4和内筒2中的任一个单独旋转或搅拌器4和内筒2同时旋转，再例如搅拌器4和内筒2同向旋转或反向旋转，从而使滚筒洗衣机100的洗涤方式多样化。
并且，利用行星齿轮部装6将主轴31的转矩传递至搅拌器4，可以利用驱动器间接驱动搅拌器4，由于搅拌器4处的负载远远小于内筒2处的负载，因此相比相关技术中具有波轮的滚筒洗衣机，作用于行星齿轮部装6的载荷得到了极大的减小，不仅利于动力的稳定传递以提高滚筒洗衣机100的性能稳定性，而且大幅降低了行星齿轮部装6损坏的风险，以延长滚筒洗衣机100的使用寿命。
根据本公开的一个实施例，滚筒洗衣机100还包括：第二轴32和制动器7，第二轴32与行星轮架611啮合，制动器7通过第二轴32控制行星轮架611是否被制动。
在一些示例中，第二轴32的侧周壁设有花键，即第二轴32形成花键轴，行星轮架611设有与第二轴32的花键配合的花键槽，第二轴32与行星轮架611通过花键与花键槽的配合固定连接，保证第二轴32与行星轮架611的同步运转。
当制动器7制动第二轴32，则行星轮架611因被制动而无法旋转；当制动器7脱离第二轴32，则行星轮架611处于自由状态。因此，通过设置制动器7，可以切换第二轴32的运行状态，从而使行星齿轮部装6在第一状态与第二状态之间切换，在第一状态和第二状态之间切换的行星齿轮部装6，可以调整搅拌器4的旋转方向，使搅拌器4与内筒2同向和反向旋转，从而配合内筒2组成适于不同工况的工作模式。
在一些示例中，主轴31内具有沿其轴向贯通的空腔311，第二轴32穿设于空腔311。例如，主轴31的中心轴线与第二轴32的中心轴线平行且重合，主轴31相对于第二轴32可旋转，由此分别带动内筒2和搅拌器4旋转，保证滚筒洗衣机100的正常工作。
如图12至图21所示，在一些示例中，第二轴32上传动连接有制动盘322，制动器7与制动盘322配合时，第二轴32被制动，由此实现行星轮架611的制动；制动器7与制动盘322脱离时，第二轴32与行星轮架611处于自由状态。
进一步地，参照图13至图16，制动器7包括：滑槽座71、制动杆72和制动驱动器73。滑槽座71设有滑道711，制动杆72在伸出位置和缩回位置之间可滑动地配合于滑道711，制动杆72位于伸出位置时与制动盘322啮合，制动杆72位于缩回位置时与制动盘322脱离，制动驱动器73安装于滑槽座71且与制动杆72传动连接，制动驱动器73驱动制动杆72在伸出位置和缩回位置之间移动。由此，通过制动驱动器73驱动制动杆72沿滑道711移动，从而实现制动杆72与制动盘322的啮合与脱离，切换方便。
根据本公开实施例的用于滚筒洗衣机的制动器7，通过制动驱动器73驱动制动杆72在伸出位置与缩回位置之间移动，利用制动杆72与滚筒洗衣机100的第二轴32上的制动盘322啮合或脱离，使第二轴32在自由状态与制动状态之间切换，进而通过行星齿轮部装6将主轴31的转矩传递至搅拌器4以驱动搅拌器4旋转，由此，搅拌器4的旋转与内筒2的旋转可以彼此组合成多种的洗涤方式，使滚筒洗衣机100的洗涤方式多样化。
并且，制动器7的部件数量少，结构更简单。通过制动驱动器73驱动制动杆72移动，利用制动杆72在伸出位置时与制动盘322啮合以使第二轴32切换至制动状态，在缩回位置时脱离制动盘322以使第二轴32切换至自由状态，因此相比相关技术中的具有波轮的滚筒洗衣机，制动杆72直接作用于第二轴32上的制动盘322，控制更方便，而且制动杆72与第二轴32之间的传动结构少，动力输送更加直接，可以稳定切换第二轴32的运行状态，利于动力的稳定传递以提高滚筒洗衣机100的性能稳定性。
因此，根据本公开实施例的用于滚筒洗衣机的制动器7，能够实现搅拌器4与内筒2协同工作的模式切换，且具有结构简单、控制方便、稳定等优点。
在一些具体示例中，制动杆72设有限位块720，滑道711内设有限位台712，通过在滑道711内设置限位台712，使其与制动杆72上的限位块720配合，从而限制了制动杆72的移动路径，即对制动杆72可进行轴向限位，防止制动杆72滑出滑道711外而脱离滑槽座71，进而保证制动器7的运行可靠性。
在一些具体示例中，滑道711内设有周向定位滑槽713，限位块720可滑动地配合于周向定位滑槽713。通过在滑道711内设置周向定位滑槽713，使制动杆72沿滑道711移动时，限位块720在周向定位滑槽713内移动，周向定位滑槽713可以对制动杆72进行周向定位，实现防转效果。
如图15和图16所示，在一些示例中，制动杆72包括：滑道配合部721、传动部722、桥部723和制动部724。
滑道配合部721与滑道711可滑动地配合，传动部722连接在滑道配合部721的一端且桥部723连接在滑道配合部721的另一端，即滑道配合部721的两端分别与传动部722和桥部723连接，制动部724连接在桥部723的远离滑道配合部721的一端，传动部722与制动驱动器73传动连接，从而通过驱动器驱动制动杆72移动，制动杆72位于伸出位置时制动部724与制动盘322啮合，制动杆72位于缩回位置时制动部724与制动盘322脱离，制动杆72的结构简单，与滑槽座71和制动驱动器73连接方便。
在一些可选的示例中，滑道配合部721的横截面和滑道711的最小横截面为相互适配的圆形，桥部723的横截面为矩形且面积小于滑道配合部721的横截面积。
也就是说，桥部723的横截面面积小于滑道711的最小横截面面积，这样可以减小制动杆72与滑道711的内壁面的配合面积，从而减少制动杆72与滑动的内壁面的摩擦力，进而减小制动杆72的移动阻力。
在一些可选的示例中，桥部723设有多个横向加强筋7231和多个纵向加强筋7232，每个横向加强筋7231沿桥部723的宽度方向延伸且多个横向加强筋7231沿桥部723的长度方向间隔设置，每个纵向加强筋7232沿桥部723的长度方向延伸且多个纵向加强筋7232沿桥部723的宽度方向间隔设置，每个纵向加强筋7232分别与多个横向加强筋7231相连。通过在桥部723上设置多个横向加强筋7231和多个纵向加强筋7232，从而提高桥部723的结构强度，保证制动器7的使用可靠性，进而延长制动器7的使用寿命。
在一些具体示例中，滑道配合部721设有多个轴向加强筋7211，每个轴向加强筋7211沿滑道配合部721的轴向延伸且多个轴向加强筋7211沿滑道配合部721的周向间隔设置，由此提高滑动配合部的结构强度，进一步保证制动器7的使用可靠性。
如图13所示，在一些示例中，滑道711内设有支撑滑槽714，传动部722可滑动地支撑于支撑滑槽714。
在一些具体示例中，滑道711内设有至少两个凸出于滑道711内表面的支撑筋，且每个支撑筋沿滑道711的长度方向延伸，相邻两个支撑筋之间限定出支撑滑槽714，传动部722支撑在支撑筋上且沿支撑滑槽714可移动。由此，通过在滑道711内设置支撑滑槽714，不仅可以对传动部722进行支撑、定位，实现防转效果，而且可以提高制动杆72与滑槽座71的滑动配合可靠性，保证驱动器的正常工作。
根据本公开的又一个实施例，制动器7还包括：制动凸轮74，驱动器为电机且通过制动凸轮74与制动杆72传动连接，制动凸轮74可以将电机的电机轴的旋转运动转化为制动杆72在滑道711内的线性运动，保证制动器7的正常工作。
在一些示例中，制动凸轮74设有偏心柱741，制动杆72设有直线滑槽725，偏心柱741可滑动地配合在直线滑槽725内。电机驱动制动凸轮74旋转时，制动凸轮74的偏心柱741进行偏心旋转，由于滑道711限定制动杆72只能沿其长度方向线性移动，因此，偏心柱741在直线滑槽725内滑动时，带动制动杆72沿滑道711的长度方向移动，运转动作连贯，使用可靠性高。
可选地，传动部722的长度方向垂直于桥部723和滑道配合部721的长度方向，直线滑槽725设于制动杆72的传动部722且沿传动部722的长度方向延伸，从而使直线滑槽725的长度方向垂直于制动杆72的线性运动方向，结构简单、紧凑，便于与制动凸轮74配合，从而实现上述功能。
在一些示例中，滑槽座71设有与滑道711连通的过孔715，制动凸轮74的一部分设在过孔715内以与制动驱动器73连接，制动凸轮74的另一部分通过过孔715伸入到滑道711内，从而便于制动凸轮74的偏心柱741与制动杆72的直线滑槽725配合。
如图12所示，在一些示例中，滑槽座71通过制动器支架75安装于外桶1的后壁，制动盘322位于外桶1的外部且安装在第二轴32伸出外桶1的一端上，制动器7位于外桶1的外部，从而与制动盘322进行配合，实现滚筒洗衣机100的不同工作模式的切换。
其中，制动盘322的侧周壁具有沿其周向排布的锁齿，制动器7的制动杆72在伸出位置和缩回位置之间可滑动，制动杆72位于伸出位置时止抵于制动盘322的相邻两个锁齿之间，制动杆72位于缩回位置时与制动盘322脱离。
在一些具体示例中，制动器支架75设有限位滑槽751，限位滑槽751沿制动盘322的径向延伸，制动杆72的伸出滑道711的部分可滑动地配合于限位滑槽751，限位滑槽751对制动杆72进行限位，不仅可以起到导向的作用，从而保证制动杆72的线性 移动，还可以对制动杆72起到保护作用，防止制动杆72在移动时被折断。
根据本公开的另一个实施例，滚筒洗衣机100还包括：用于检测驱动器的功率的检测装置(未示出)，当检测装置检测到驱动器的功率达到预定值时，制动器7通过第二轴32控制行星轮架611被允许自由旋转，从而使搅拌器4与内筒2同向旋转，防止内筒2内的衣物严重缠绕而发生撕损，安全性高。
如图1-图3所示，根据本公开的一个实施例，滚筒洗衣机100还包括：内筒支架201，内筒支架201安装于内筒2的后壁且位于内筒2的后壁和外桶1的后壁之间，主轴31通过内筒支架201与内筒2转动连接且可旋转地支撑于外桶1的后壁。也就是说，主轴31可以直接驱动内筒2旋转，同时可以通过行星齿轮部装6带动搅拌器4旋转，这样行星齿轮部装6不易损坏。
具体地，内筒2包括轴向两端分别敞开的内筒筒体21和设于内筒筒体21后端的内筒后盖22，内筒后盖22的外周缘形成沿内筒筒体21的轴向延伸的折边，内筒筒体21的后端与内筒后盖22的折边连接。内筒支架201通过连接件(例如，螺钉)固定在内筒筒体21以及内筒后盖22的折边的连接处，从而将内筒2固定于内筒支架201上，使其可以随内筒支架201相对于外桶1旋转。
在一些示例中，内筒支架201具有中心轴部2011和架部2012，中心轴部2011沿外桶1的轴向延伸，且中心轴部2011可旋转地支撑在外桶1的后壁上，架部2012连接在中心轴部2011的侧周壁，内筒2安装在架部2012上。
可选地，内筒支架201的架部2012包括多个(例如三个)沿内筒2的周向分布的连接臂，每个连接臂沿内筒2的径向延伸，并且每个连接臂的内端与中心轴部2011的侧周壁连接，每个连接臂的外端通过连接件与内筒2连接，通过采用多个连接臂连接内筒2，既可以保证内筒支架201与内筒2的连接可靠性和稳定性，又可以减少内筒支架201的材料用量，降低材料成本和重量，从而提高该滚筒洗衣机100的性价比。可以理解的是，架部2012与中心轴部2011可以一体形成。
在一些示例中，外桶1的后壁设有安装孔11且安装孔11内设有主轴轴承座12，主轴31由设于主轴轴承座12内的主轴轴承314可旋转地支撑。也就是说，外桶1的安装孔11内设有主轴轴承座12和安装于主轴轴承座12内的主轴轴承314，主轴31沿安装孔11的轴向延伸且伸入安装孔11内，并通过主轴轴承314安装于外桶1的后壁，由此主轴31可以相对于外桶1旋转。
参照图4和图5，并结合图1、图21和图23，在一些示例中，主轴31上套设有主轴轴套316，主轴轴套316上套设有主轴法兰315，内筒支架201连接在主轴法兰315上，连接方便、可靠。
可选地，主轴轴套316套装在主轴31上，主轴法兰315套装在主轴轴套316上，内筒支架201浇注在主轴法兰315上，例如内筒支架201可以为注铝件，通过机加工，可将主轴31、主轴轴套316及主轴法兰315一体加工成型，有利于提高滚筒洗衣机100的生产效率。
在一些示例中，行星齿轮部装6套设有部装密封件641，部装密封件641密封行星齿轮部装6与主轴法兰315之间的缝隙，从而保证行星齿轮部装6与主轴法兰315之间的连接密封性。
进一步地，行星齿轮部装6的外周壁设有环形限位圈，耐磨套642外套在行星齿轮部装6且一端止抵环形限位圈，且耐磨套642位于行星齿轮部装6与部装密封件641之间，部装密封件641形成环形且套装在耐磨套642上，部装密封件641的内表面与耐磨套642密封连接，部装密封件641的外表面分别与主轴法兰315和内筒支架201密封连接。通过在部装密封件641与行星齿轮部装6之间设置耐磨套642，使耐磨套642与部装密封件641配合，可以保证尺寸精度，并提高耐磨性。
如图12所示，根据本公开的一个实施例，主轴31传动连接有皮带轮312，驱动器为电机5，且电机5通过张紧在皮带轮312上的皮带3121驱动皮带轮312旋转，即皮带312绕设在电机轴51与皮带轮312上。由此，通过在主轴31上设置皮带轮312以及皮带3121，从而通过皮带3121实现主轴31与驱动器的传动连接，可以缓和冲击和振动载荷，使主轴31运转平稳，且工作时产生的噪音较低。
在一些示例中，皮带轮312、皮带3121和驱动器均位于外桶1的外部，皮带轮312被止挡在外桶1的后壁和主轴31上的锁紧螺母313之间。也就是说，皮带轮312固定连接在主轴31上且位于外桶1的后壁与锁紧螺母313之间，通过设置锁紧螺母313，可以保证皮带轮312的定位安装，这样驱动器通过皮带3121带动皮带轮312旋转，而皮带轮312带动主轴31旋转，由此实现皮带轮312与主轴31的同步旋转。
如图22和图23所示，根据本公开的又一个实施例，搅拌器4具有喷水孔41，滚筒洗衣机100还包括供水装置(未示出)，供水装置分别与外桶1和搅拌器4连通，供水装置将外桶1内的水供给到搅拌器4并由喷水孔41喷到内筒2内。
衣物在洗涤过程中，供水装置为搅拌器4供水，喷水孔41向内筒2内的衣物喷水，从而起到浸湿衣物的作用，提高了衣物浸湿效果，同时搅拌器4可以搅拌内筒2中的水，使洗涤方式多样化，从而提高衣物洗涤效果，并有利于减少洗涤时间。
在一些可选的示例中，供水装置包括供水管和供水泵，供水管具有第一端和第二端，供水管的第一端与外桶1连通，供水管的第二端连接至搅拌器4，从而将外桶1内的水通过供水管供给到搅拌器4。这里，“供水管的第二端连接至搅拌器4”中的“连接” 应作广义理解，例如，供水管可以与搅拌器4物理连接，也可以不物理连接，只要从供水管的第二端出来的水能够供给到搅拌器4即可。
由此，将外桶1的内腔中的水通过供水管供给到搅拌器4，可以起到浸湿衣物的作用，提高了衣物浸湿效果。通过将供水装置与外桶1的内腔连通，从而可以利用外桶1内的洗涤水浸湿衣物，无需额外的水源，减少用水量。可以理解的是，在一些不设置循环泵的机型中，供水管的第一端也可以直接连接至供水源供水，例如外界水龙头，而非利用洗衣机内的循环水。
在一些具体示例中，供水管的第一端与外桶1的内腔的底部连通。这样，供水泵可以将外桶1的内腔的底部的水泵送到搅拌器4，即使滚筒洗衣机100在最低水位的洗涤模式下，供水装置仍然可以保证向搅拌器4供水，进而保证滚筒洗衣机100在不同洗涤模式下的浸湿效果和洗涤效果。
在一些示例中，搅拌器4内具有集水腔42和分水道43，集水腔42与供水装置连通，喷水孔41通过分水道43与集水腔42连通。通过在搅拌器4内设置集水腔42和分水道43，使供水装置可以将水输送至集水腔42以及分水道43中，最终从喷水孔41向内筒2中喷水，从而浸湿衣物，提高衣物浸湿效果，进而提高洗涤效果。
在一些示例中，搅拌器4的朝向内筒2内部的表面设有多个凸筋44，每个凸筋44沿搅拌器4的径向延伸且多个凸筋44沿搅拌器4的周向间隔设置，喷水孔41形成在凸筋44上。洗涤衣物时，喷水孔41朝向内筒2的内腔喷水，并且凸筋44可以使内筒2中的水产生涡流，带动衣物旋转、翻滚，从而提升衣物洗涤效果。
在一些具体示例中，搅拌器4为波轮，即该滚筒洗衣机100的内筒2底部设有波轮。衣物洗涤过程中，衣物在内筒2中不断地被提升摔下，再提升再摔下，可以将衣物洗涤干净，同时，在波轮的作用下，本申请滚筒洗衣机100在传统的摔打洗(只是内筒转动)基础上再增加波轮对衣物的揉搓作用，从而进一步提升洗涤效果，缩短洗涤时间。
如图21和图23所示，在另一些可选的示例中，第二轴32内具有供水通道320，供水装置通过供水通道320将外桶1内的水供给到搅拌器4。通过在第二轴32内设置供水通道320，使第二轴32具有运输水的功能，从而通过供水装置将外桶1内的洗涤水运输至第二轴32的供水通道320内，最终从喷水孔41喷到外桶1内。
在一些示例中，第二轴32的伸出外桶1的一端设有转接头323，供水装置通过转接头323与第二轴32相连。通过在第二轴32的伸出外桶1的一端设置转接头323，从而密封供水通道320的进水端，使供水装置将外桶1内的水运输至供水通道320内。
在一些具体示例中，转接头323外套在第二轴32的伸出外桶1的一端，且转接头 323与第二轴32之间设有转接头轴承3231，转接头轴承3231的内圈与第二轴32固定连接，转接头轴承3231的外圈与转接头323固定连接，转接头轴承3231可以为并排布置的两个滚珠轴承，还可以为一个滚柱轴承。由此，通过转接头轴承3231实现第二轴32与转接头323的可转动连接。
有利地，第二轴32的伸出外桶1的一端套设有转接头密封件3232，转接头密封件3232相对于转接头轴承3231更加远离第二轴32的轴向中心处，转接头密封件3232密封第二轴32与转接头323之间的缝隙。
具体地，第二轴32的伸出外桶1的一端套设有沿其轴向分布的转接头密封件3232和转接头轴承3231，且转接头密封件3232位于转接头轴承3231的外侧，转接头密封件3232分别与第二轴32和转接头323密封连接，从而保证转接头323与第二轴32的外侧壁的密封连接，防止第二轴32的供水通道320内的水进入主轴31的空腔311中而影响其他部件的正常工作。
在一些具体示例中，转接头323内设有耐磨环324，耐磨环324内嵌在转接头323内侧，第二轴32的伸出外桶1的一端伸入耐磨环324内，且转接头轴承3231与转接头密封件3232均套设在第二轴32上且位于第二轴32的外侧壁与耐磨环324之间。
也就是说，耐磨环324位于转接头323与转接头轴承3231之间以及转接头323与转接头密封件3232之间。通过在转接头323内设置耐磨环324，使转接头轴承3231的外圈、转接头密封件3232与耐磨环324配合，减少转接头323的磨损，从而延长转接头323的使用寿命。
在一些示例中，第二轴32上套设有轴密封件325，轴密封件325设置在第二轴32上且位于第二轴端轴承3212的外侧，即轴密封件325相对于第二轴端轴承3212更加远离第二轴32的轴向中心处，轴密封件325密封第二轴32与行星轮外壳62之间的缝隙，防止第二轴32的供水通道320内的水通过第二轴32与行星轮外壳62之间缝隙进入主轴31的空腔311以及行星齿轮部装6中。
下面结合图1-图23，详细描述根据本公开的滚筒洗衣机100的一些具体实施例。
如图1、图21和图23所示，根据本公开一个具体实施例的滚筒洗衣机100包括：外桶1、内筒2、主轴31、第二轴32、驱动器(如下述的电机5)、行星齿轮部装6、制动器7。

搅拌器4可旋转地设在内筒2的底部且与行星齿轮部装6(如下述的行星轮外壳62)配合。

行星齿轮组件61包括行星轮架611、三个行星齿轮612和行星轮外齿壳613。行星轮架611包括行星轮支架6111、行星轮固定盘6116。行星轮支架6111的一侧设有多个安装凸台6112、多个行星轮安装座6114，多个安装凸台6112与多个行星轮安装座6114沿行星轮架611的周向交替布置，每个行星轮安装座6114设有行星轮固定轴6115，行星轮固定轴6115的一端置于行星轮安装座6114内，另一端置于行星轮固定盘6116的适于配合的限位孔6118内，用于安装行星齿轮612；每个安装凸台6112设有定位柱6113，行星轮固定盘6116上设有与定位柱6113配合的定位孔6117，通过在定位孔6117处焊接定位柱6113，或定位柱6113与定位孔6117紧配合，从而将行星轮固定盘6116连接在行星轮支架6111上。三个行星齿轮612安装在行星轮架611上且分别与行星轮外齿壳613啮合。
行星齿轮组件61的行星轮外齿壳613上设有凸出于外表面的凸缘6131，行星轮外壳62的内表面设有与凸缘6131适配的卡槽621，从而将行星轮外齿壳613与行星轮外 壳62固定连接。

下面详细描述根据本公开实施例的滚筒洗衣机100的制动器7。
制动器7设在外桶1的后部且包括滑槽座71、制动杆72、制动驱动器73和制动凸轮74。
滑槽座71通过制动器支架75设在外桶1的后壁上，制动器支架75上设有沿制动盘322的径向延伸的限位滑槽751。滑槽座71内设有线性延伸的滑道711、周向定位滑槽713以及支撑滑槽714，滑道711内设有限位台712，滑槽座71还具有与滑道711连通的过孔715。
制动杆72在伸出位置和缩回位置之间可滑动地配合于滑道711。制动杆72包括：滑道配合部721、传动部722、桥部723和制动部724，滑道配合部721的两端分别与传动部722、桥部723连接，制动部724连接在桥部723的远离滑道配合部721的一端。
滑道配合部721与滑道711可滑动地配合，且滑道配合部721的横截面和滑道711的最小横截面为相互适配的圆形，滑道配合部721设有多个轴向加强筋7211，每个轴向加强筋7211沿滑道配合部721的轴向延伸且多个轴向加强筋7211沿滑道配合部721的周向间隔设置。
传动部722可滑动地支撑于支撑滑槽714。传动部722的一侧设有限位块720，限位块720可滑动地配合于周向定位滑槽713，通过在滑道711内设置限位台712，使其与制动杆72上的限位块720配合，从而限制制动杆72的移动路径，即对制动杆72可进行轴向限位，防止制动杆72滑出滑道711外而脱离滑槽座71，进而保证制动器7的运行可靠性，传动部722的另一侧设有直线滑槽725。
桥部723设有多个横向加强筋7231和多个纵向加强筋7232，每个横向加强筋7231沿桥部723的宽度方向延伸且多个横向加强筋7231沿桥部723的长度方向间隔设置，每个纵向加强筋7232沿桥部723的长度方向延伸且多个纵向加强筋7232沿桥部723的宽度方向间隔设置，每个纵向加强筋7232分别与多个横向加强筋7231相连。
制动杆72位于伸出位置时制动部724与制动盘322啮合，制动杆72位于缩回位置时制动部724与制动盘322脱离。
制动凸轮74安装在滑槽座71的过孔715处且具有偏心柱741，制动驱动器73用 于驱动制动凸轮74旋转，从而使偏心柱741偏心旋转，偏心柱741与传动部722上的直线滑槽725配合，进而驱动制动杆72线性移动。
根据本公开的另一个具体实施例，第二轴32的伸出外桶1后壁的一端设有用于连接供水装置的转接头323，转接头323通过转接头轴承3231外套在第二轴32上，且第二轴32还外套有与转接头323密封连接的转接头密封件3232，转接头密封件3232位于转接头轴承3231的外侧。
进一步地，第二轴32内具有沿其轴向延伸的供水通道320，供水通道320的一端与转接头323连通，供水通道320的另一端与搅拌器4连通。搅拌器4具有用于连通供水通道320的集水腔42、由凸筋44限定的分水道43以及设在凸筋44上的喷水孔41。
供水装置包括供水管和供水泵，供水管的第一端与外桶1连通，供水管的第二端与供水通道320连通，供水泵设在供水管上，从而在供水泵工作时，将外桶1内的水通过供水管、供水通道320输送至搅拌器4中。
下面详细描述根据本公开的实施例的滚筒洗衣机100的工作过程。
滚筒洗衣机100以洗涤模式运行时，制动驱动器73驱动制动杆72移动至伸出位置，制动杆72的制动部724与制动盘322啮合以锁死制动盘322，使得第二轴32固定不动，由于行星齿轮部装6的行星轮架611与第二轴32通过花键结构配合，因此行星轮架611也固定不动，设在行星轮架611上的多个行星齿轮612仅可以自转。
随后，电机5在运行时，通过皮带3121带动皮带轮312正向旋转，从而驱动主轴31、内筒2正向旋转，由于主轴31与多个行星齿轮612啮合，主轴31在旋转时可以同时带动多个行星齿轮612自转，进而带动行星轮外齿壳613反向旋转，而由于行星轮外齿壳613与行星轮外壳62连接、行星轮外壳62与搅拌器4连接，因此主轴31通过行星齿轮部装6带动搅拌器4反向转动。
在此过程，衣物在内筒2中不断地被提升摔下，再提升再摔下，可以将衣物洗涤干净，同时，在搅拌器4的作用下，本申请滚筒洗衣机在传统的摔打洗(只是内筒转动)基础上再增加波轮对衣物的摩擦揉搓作用，从而更进一步提升洗涤效果，缩短洗涤时间。
当搅拌器4具有喷水孔41时，供水泵可以通过第二轴2的供水通道320，或者通过供水管向搅拌器4供水，从而使喷水孔41向内筒2内的衣物喷水，起到浸湿衣物的作用，提高了衣物浸湿效果，进一步提高衣物洗涤效果。
可以理解的是，滚筒洗衣机100处于洗涤模式时，行星齿轮部装6将主轴31的正向旋转传递为搅拌器4的反向旋转，同时行星齿轮部装6与主轴31传动连接，可以对主轴31进行减速，从而使搅拌器4的旋转速度低于主轴31的旋转速度。这里的“正 向旋转”和“反向旋转”为相对说法，并不指代具体的逆时针或顺时针旋转方向。
滚筒洗衣机100以脱水模式运行时，制动驱动器73驱动制动杆72移动至缩回位置，制动杆72的制动部724松开制动盘322，使第二轴32处于自由状态。
随后，电机5通过皮带3121带动皮带轮312正向旋转时，可以带动主轴31、内筒2正向旋转，然后主轴31带动行星齿轮612自转，进而带动行星轮外壳62和搅拌器4与内筒2同向且同速旋转。
根据本公开实施例的滚筒洗衣机100，通过设置驱动器，利用驱动器通过主轴31驱动内筒2，动力传递的级数更少，动力输送更加直接，使内筒2运行更稳定，而在主轴31与搅拌器4之间设置行星齿轮部装6，利用行星齿轮部装6将主轴31的转矩传递至搅拌器4，由于搅拌器4处的负载远远小于内筒2处的负载，因此相比相关技术中具有波轮的滚筒洗衣机，作用于行星齿轮部装6的载荷得到了极大的减小，大幅降低了行星齿轮部装6损坏的风险，以延长滚筒洗衣机100的使用寿命。
根据本公开实施例的滚筒洗衣机100的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本公开的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本公开的实施例，本领域的普通技术人员可以理解：在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公开的范围由权利要求及其等同物限定。
