其中，驱动组件用于驱动洗涤筒转动。该驱动组件可以为驱动电机，优选地，驱动组件包括转轴以及套设在转轴上的定子和转子。
优选地，如图4所示，加强构件2上设有用于穿设转轴的第一通孔21，前壳1上设有用于穿设转轴的第二通孔11，第一通孔21和第二通孔11垂直对应，转轴的一端依次穿过第二通孔11和第一通孔21与设置在洗涤筒底部的三脚架连接。
优选地，第二通孔11的轴线方向与第一通孔21的轴心方向相重合，使得第二通孔11和第一通孔21同轴设置，且第二通孔11的轴线方向与转轴的轴线方向相重合，避免了转轴出现偏心现象，从而降低了滚筒洗衣机的噪音和振动，提高了滚筒洗衣机的稳定性，进而改善了用户的使用体验。
优选地，由于第二通孔11和转轴之间还设有轴套，将第二通孔11的孔径设置为大于第一通孔21的孔径，且第一通孔21的孔径与转轴的外径相匹配，不仅使得转轴与第二通孔11和第一通孔21均能够很好的配合，而且最大限度地提高了前壳1的应力集中部的强度，使得直驱电机能够承担滚筒洗衣机的洗涤筒以及工作状态时的负载衣物。
为了提高加强构件2和前壳1连接的稳定性，加强构件2与前壳1以焊接的方式连接，提高了前壳1的强度，降低了直驱电机的成本。当然，加强构件2也可以与前壳1一体成型，可通过注塑成型工艺进行生产，加工工艺简单，成本低。

进一步地，多个卡爪31绕加强构件2的周向均匀设置，使得前壳1与洗涤筒之间受力均匀，从而进一步提高了前壳1与洗涤筒连接的稳定性。
进一步地，卡爪31的宽度由卡爪31与前壳1的连接端向卡爪31的自由端逐渐减小，由于应力由前壳1的中心部位向前壳1的外沿逐渐减小，将卡爪31的宽度设置为由卡爪31与前壳1的连接端向卡爪31的自由端逐渐减小，与应力的分布趋势相匹配，相对于卡爪31的宽度不变的技术方案，本实施例的卡爪不仅能够增大前壳与洗涤筒的接触面积，还能够降低成本。
优选地，卡爪31的自由端具有圆弧结构，使得前壳1和洗涤筒装配时，由于圆弧结构，能够方便地将卡爪31装卡至洗涤筒的的卡合部内，实现了前壳1与洗涤筒的卡接装配，操作更加方便、快捷，实现了直驱电机与洗涤筒的预定位，提高了滚筒洗衣机的装配进度，有利于滚筒洗衣机的安装作业。

采用上述直驱电机，将设于前壳1上的卡爪31与设于洗涤筒上的卡槽卡合连接，防止了直驱电机相对于洗涤筒产生位移，实现了直驱电机与洗涤筒的预定位，有利于滚筒洗衣机的安装作业；再将连接螺杆依次穿过第一螺纹孔、连接孔12和第二螺纹孔将后壳、前壳1和洗涤筒螺纹连接，从而将直驱电机和洗涤筒连接固定，使得直驱电机与洗涤筒连接的更加固定，从而提高了直驱电机与洗涤筒连接的牢固性，提高了滚筒洗衣机的装配效率。
此外，本发明还提供了一种滚筒洗衣机，该滚筒洗衣机包括上述直驱电机，采用上述直驱电机，通过在前壳1上设置加强构件2提高了前壳1的强度，将直驱电机的前壳1和外壳作为轴承座时，使得直 驱电机能够承担滚筒洗衣机的洗涤筒以及工作状态时的负载衣物，又由于前壳1和外壳的体积较小，从而避免了对滚筒洗衣机的内筒深度以及内筒容量，降低了滚筒洗衣机的成本，进而改善了用户的使用体验。
实施例三
基于背景技术中提到的现有技术中的问题，本发明通过在前壳上设置加强构件，提高了前壳的强度，将直驱电机的前壳和后壳作为轴承座时，使得直驱电机能够承担滚筒洗衣机的洗涤筒以及工作状态时的负载衣物，又由于前壳和后壳的体积较小，从而避免了对滚筒洗衣机的内筒深度以及内筒容量，降低了滚筒洗衣机的成本，进而改善了用户的使用体验。
参见图5至图7，图5是本发明的实施例三的直驱电机的前壳的结构示意图；图6是图5中I-I部分的局部放大图；图7是本发明的实施例三的直驱电机的前壳的后视图。本发明提供了一种用于滚筒洗衣机的直驱电机，直驱电机包括前壳1、后壳以及设置在前壳和后壳之间的驱动组件。如图5所示，前壳1上设有至少一圈连接孔以及加强构件2，加强构件2用于提高前壳1的强度。
如图5所示，加强构件2设置在前壳1的中心部位。将直驱电机的前壳1和后壳作为轴承座，应力集中在前壳1的中心部位，将加强构件2设置在前壳1的中心部位，能够有效提高前壳1的中心部位(即应力集中部位)的强度，使得直驱电机能够承担滚筒洗衣机的洗涤筒以及工作状态时的负载衣物，使得滚筒洗衣机能够正常的运行，进而改善了用户的使用体验。当然，加强构件2的实际安装位置不限于上述举例的安装位置，本领域技术人员可以在实际的应用中灵活地设置加强构件2的实际安装位置，只要通过加强构件2能够提高前壳1的应力集中部的强度即可。
其中，驱动组件用于驱动洗涤筒转动。该驱动组件可以为驱动电机，优选地，驱动组件包括转轴以及套设在转轴上的定子和转子。
优选地，如图7所示，加强构件2上设有用于穿设转轴的第一通孔21，前壳1上设有用于穿设转轴的第二通孔11，第一通孔21和第二通孔11垂直对应，转轴的一端依次穿过第二通孔11和第一通孔21与设置在洗涤筒底部的三脚架连接。
优选地，第二通孔11的轴线方向与第一通孔21的轴心方向相重合，使得第二通孔11和第一通孔21同轴设置，且第二通孔11的轴线方向与转轴的轴线方向相重合，避免了转轴出现偏心现象，从而降低了滚筒洗衣机的噪音和振动，提高了滚筒洗衣机的稳定性，进而改善了用户的使用体验。
优选地，由于第二通孔11和转轴之间还设有轴套，将第二通孔11的孔径设置为大于第一通孔21的孔径，且第一通孔21的孔径与转轴的外径相匹配，不仅使得转轴与第二通孔11和第一通孔21均能够很好的配合，而且最大限度地提高了前壳1的应力集中部的强度，使得直驱电机能够承担滚筒洗衣机的洗涤筒以及工作状态时的负载衣物。
为了提高加强构件2和前壳1连接的稳定性，加强构件2与前壳1以焊接的方式连接，提高了前壳1的强度，降低了直驱电机的成本。当然，加强构件2也可以与前壳1一体成型，可通过注塑成型工艺进行生产，加工工艺简单，成本低。
优选地，加强构件2上设有多个焊接点，多个焊接点22绕加强构件2的周向设置。进一步地，多个焊接点22绕加强构件2的周向均匀设置，使得前壳1与加强构件2之间受力均匀，从而进一步提高了前壳1与加强构件2连接的稳定性。

优选地，定位构件3包括多个定位块31，多个定位块31绕加强构件2的周向设置。当然，定位构件3也可以采用卡爪的结构、卡扣的结构或者卡勾的结构等，本领域技术人员可以在实际的应用中灵 活地设置定位构件3的结构形式，只要通过定位构件3实现前壳1与洗涤筒以卡合的方式连接即可。
进一步地，多个定位块31绕加强构件2的周向均匀设置，使得前壳1与洗涤筒之间受力均匀，从而进一步提高了前壳1与洗涤筒连接的稳定性。
进一步地，如图6所示，定位块31包括定位部311和限位部312，定位部311从加强构件2上沿水平方向延伸，限位部312从定位部311上倾斜延伸，如图6所示，限位部312向纸面的上方倾斜。使得在初始卡合时，定位部311远离限位部312的一端能够沿着被定位构件3的导向部向被定位构件的定位部移动，使得定位块31的定位部311卡在被定位构件的定位部中，从而实现了前壳1与洗涤筒的卡接装配，操作更加方便、快捷；当定位块31的限位部312与被定位构件3的导向部接触时，实现了定位块31的定位部311的限位，避免了定位块31的定位部311继续沿水平方向移动，从而实现了直驱电机与洗涤筒的预定位，提高了滚筒洗衣机的装配进度，有利于滚筒洗衣机的安装作业。
优选地，定位部311和限位部312通过圆弧倒角连接，使得前壳1和洗涤筒装配时，由于圆弧倒角结构，能够方便地将定位块31的定位部311装卡至被定位构件的定位部内。

优选地，限位部312为三角形结构。
优选地，定位部311和限位部312一体成型，可通过注塑成型工艺进行生产，加工工艺简单，成本低。当然，定位部311和限位部312也可以固定连接，如焊接连接等。
如图5所示，前壳1上还设有两圈连接孔。尽管图中未示出，还包括连接螺杆，洗涤筒的底部设有与两圈连接孔对应的两圈螺纹孔，连接螺杆依次穿过连接孔以及与其相对应的螺纹孔将前壳1和洗涤筒螺纹连接。
优选地，一圈连接孔设置在前壳1的外沿，另一圈连接孔设置在前壳1的外沿和加强构件2的外沿之间。
优选地，每圈连接孔均包括多个连接孔12，多个连接孔12绕前壳1的周向设置。进一步地，多个连接孔12绕前壳1的周向均匀设置，进一步提高了前壳1与洗涤筒连接的稳定性。
优选地，每圈螺纹孔包括多个螺纹孔，多个螺纹孔绕洗涤筒的周向设置。进一步地，多个螺纹孔绕洗涤筒的周向均匀设置，多个螺纹孔与多个连接孔12一一对应。
本领域技术人员能够理解的是，连接孔12的圈数不限于两圈，可以根据实际情况改变其数量，但是无论连接孔12的圈数为多少，将每圈连接孔12绕前壳1的周向设置，且相邻的两圈连接孔12交错设置，以提高前壳1与洗涤筒连接的稳定性。
采用上述直驱电机，将设于加强构件2上的定位部311与设于洗涤筒上的被定位构件的定位部卡合连接，并通过设置在定位部311上的限位部312限定定位块31的定位部311的横向位移，防止了直驱电机相对于洗涤筒产生位移，实现了直驱电机与洗涤筒的预定位，有利于滚筒洗衣机的安装作业；再将连接螺杆依次穿过第一螺孔、连接孔12和第二螺孔将后壳、前壳1和洗涤筒螺纹连接，从而将直驱电机和洗涤筒连接固定，使得直驱电机与洗涤筒连接的更加固定，从而提高了直驱电机与洗涤筒连接的牢固性，提高了滚筒洗衣机的装配效率。
此外，本发明还提供了一种滚筒洗衣机，该滚筒洗衣机包括上述直驱电机，采用上述直驱电机，通过在前壳1上设置加强构件2提高了前壳1的强度，将直驱电机的前壳1和后壳作为轴承座时，使得直驱电机能够承担滚筒洗衣机的洗涤筒以及工作状态时的负载衣物，又由于前壳1和后壳的体积较小，从而避免了对滚筒洗衣机的内筒深度以及内筒容量，降低了滚筒洗衣机的成本，进而改善了用户的使用体验。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
