Description

用于衣物处理设备的直驱电机及衣物处理设备 技术领域
本发明属于衣物处理技术领域，具体提供一种用于衣物处理设备的直驱电机及衣物处理设备。
背景技术
衣物处理设备是能够对衣物进行洗涤、甩干、干洗和/或烘干的机器，常见的衣物处理设备包括洗衣机、洗鞋机、干衣机、干洗机和洗干一体机等。以滚筒洗衣机为例，其电机的驱动方式主要包括电机皮带驱动和直驱电机驱动，相比于电机皮带驱动，直驱电机驱动具有节约空间，噪音低和运行平稳等优点。
现有技术中，仍以滚筒洗衣机为例，采用直驱电机的滚筒洗衣机的结构一般为通过直驱电机与滚筒的内筒连接，在直驱电机和滚筒之间设置有轴承座，并且定子设置在轴承座上，由于轴承座的存在，会极大地占用了滚筒后部的空间，从而使滚筒尤其是内筒的空间变小，从而极大地压缩了整机的容积。
因此，本领域需要一种新的用于衣物处理设备的直驱电机及衣物处理设备来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有采用直驱电机的衣物处理设备由于直驱电机布置不合理，从而导致占用较多空间的问题。
本发明的技术方案1提供了一种用于衣物处理设备的直驱电机，该衣物处理设备包括衣物处理筒，该直驱电机包括前壳、后壳、定子、转子和驱动轴，前壳和后壳组成直驱电机的电机外壳，定子和转子均设置在电机外壳内，转子设置在靠近前壳的一侧，定子设置在靠近后壳的一侧，转子通过驱动轴与衣物处理筒连接，前壳和后壳中的至少一个与驱动轴之间设置有支撑轴承。

在另一方面，本发明还提供了一种衣物处理设备，该衣物处理设备包括上述的直驱电机。
在上述衣物处理设备的优选技术方案中，该衣物处理设备为滚筒洗衣机或滚筒干衣机。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过将电机外壳作为驱动轴的支撑构件，与现有技术中的衣物处理设备相比，本发明通过将电机外壳代替轴承座来对支撑轴承进行支撑，即通过前壳和/或后壳来对支撑轴承进行支撑，从而可以省略轴承座，进而使直驱电机和衣物处理筒之间的间隙增大，该间隙可以用来扩充衣物处理筒的内部空间，使整机的容积增大，从而使衣物处理设备可以对更多的衣物进行衣物处理，提升用户体验。
进一步地，在前壳和驱动轴之间设置第一支撑轴承，在后壳和驱动轴之间设置第二支撑轴承，通过这样的设置，可以对驱动轴的两 个位置进行支撑，即在转子的前侧对驱动轴的靠近中部的位置进行支撑，在定子的后侧对驱动轴的后部进行支撑，从而提高驱动轴的支撑强度，使驱动轴更平稳地运行，进而稳定地驱动衣物处理筒转动。
更进一步地，通过第一限位构件和第二限位构件的配合能够使转子和驱动轴之间进行更稳定、有效地传动，避免发生摩擦打滑的情况，使驱动轴的外壁表面和转子的内壁表面均不易发生磨损，从而提高驱动轴和转子的使用寿命。
再进一步地，转子上设置有容纳部，使定子能够设置在容纳部内，通过这样的设置，可以进一步降低直驱电机的轴向距离，从而进一步增大衣物处理筒的内部空间，进而进一步提高整机的容积。
此外，本发明在上述技术方案的基础上进一步提供的衣物处理设备由于采用了上述的直驱电机，进而具备了上述直驱电机所具备的技术效果，并且相比于改进前的衣物处理设备，本发明的衣物处理设备的衣物处理筒的容积更大，从而使衣物处理设备可以对更多的衣物进行衣物处理，提升用户体验。
本发明的技术方案2提供了一种衣物处理设备，该衣物处理设备包括外筒、设置在外筒中的内筒以及与内筒连接的直驱电机，直驱电机包括与外筒相连的电机外壳和设置在电机外壳内的驱动组件，驱动组件包括转子、定子和驱动轴，转子和定子均设置在电机外壳内，转子通过驱动轴与内筒连接。

在上述衣物处理设备的优选技术方案中，支撑架为三脚架。
在上述衣物处理设备的优选技术方案中，支撑架与内筒固定连接或者设置为一体。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过将定子和转子全部设置在电机外壳内，与现有技术中的衣物处理设备相比，本发明无需通过轴承座来固定定子，即可以通过电机外壳来代替轴承座对驱动组件进行支撑，从而可以省略轴承座，进而使直驱电机和内筒之间的间隙增大，该间隙可以用来扩充内筒的内部空间，使整机的容积增大，从而使衣物处理设备可以对更多的衣物进行衣物处理，提升用户体验。
进一步地，在前壳和驱动轴之间设置第一支撑轴承，在后壳和驱动轴之间设置第二支撑轴承，通过这样的设置，可以对驱动轴的两个位置进行支撑，即在转子的前侧对驱动轴的靠近中部的位置进行支撑，在定子的后侧对驱动轴的后部进行支撑，从而提高驱动轴的支撑强度，使驱动轴更平稳地运行，进而稳定地驱动衣物处理筒转动。
更进一步地，通过密封构件可以对前壳、驱动轴和外筒之间的间隙进行密封，从而避免水和灰尘从该间隙处进入到直驱电机内部从而浸染直驱电机，从而不会影响直驱电机的正常运行，更不会引发安全事故，始终保证衣物处理设备能够安全、平稳地运行。
再进一步地，外筒上设置有容纳部，并且直驱电机全部设置在容纳部内，通过这样的设置，使外筒的后部对直驱电机形成包覆，即直驱电机不会单独暴露在外，从而使整体的结构更为紧凑，并且由于省略了轴承座，直驱电机本身的轴向长度减小，从而也不会使内筒的容积受到影响，即不会减小内筒的容积，并且后壳优选地与外筒的后侧齐平，从而提高整体的美观性。

具体地，如图1和2所示，本发明的滚筒洗衣机包括滚筒，该滚筒包括外筒1以及设置在外筒1中的内筒2，本发明的直驱电机包括前壳6、后壳7、定子4、转子3和驱动轴5，前壳6和后壳7组成直驱电机的电机外壳，定子4和转子3均设置在电机外壳内，电机外壳与外筒1相连，转子3设置在靠近前壳6的一侧，定子4设置在靠近后壳7的一侧并且与后壳7固定连接，转子3通过驱动轴5与内筒2连接，前壳6和后壳7中的至少一个与驱动轴5之间设置有支撑轴承。其中，可以在前壳6和驱动轴5之间设置支撑轴承，也可以在后壳7和驱动轴5之间设置支撑轴承，还可以在前壳6和驱动轴5以及后壳7和驱动轴5之间均设置支撑轴承，本领域技术人员可以在实际应用中灵活地设置支撑轴承的数量和位置，只要通过支撑轴承能够对驱动轴5进行支撑即可。
需要说明的是，直驱电机一般安装在滚筒洗衣机滚筒的后侧，即安装在滚筒远离开门的一侧，因此在本发明的描述中，前壳6指的是电机外壳的靠近内筒2一侧的壳体，后壳7指的是电机外壳的远离内筒2一侧的壳体，在实际应用中，前壳6和后壳7可以通过螺钉连接等方式固定连接，还可以将前壳6和后壳7设置为一体，本领域技术人员可以在实际应用中灵活地设置前壳6和后壳7的设置以及连接方式，这种设置及连接方式的改变并不偏离本发明的原理和范围。
优选地，支撑轴承包括第一支撑轴承8和第二支撑轴承9，第一支撑轴承8设置在驱动轴5和前壳6之间，第二支撑轴承9设置在驱动轴5和后壳7之间。如图1和2所示，驱动轴5的前端与内筒2连接，通过第一支撑轴承8可以对驱动轴5的靠近中部位置进行支撑，通过第二支撑轴承9可以对驱动轴5的靠近后部位置进行支撑，通过这样的设置，可以实现驱动轴5两个位置的稳定支撑，提高支撑强度，并且通过前壳6和后壳7，可以充分地代替轴承座来对第一支撑轴承8和第二支撑轴承9进行支撑，进而省略轴承座。在一种具体的实施方式中，如图1和2所示，前壳6的中部贯通形成用于容纳第一支撑轴承8的第一支撑面，第一支撑面和第一支撑轴承8的外圈相适配，即，第一支撑轴承8的外圈与第一支撑面相贴合，第一支撑轴承8的内圈与驱动轴5相贴合，后壳7的中部形成用于容纳第二支撑轴承9的第二支撑面，第二 支撑面和第二支撑轴承9的外圈相适配，即，第二支撑轴承9的外圈与第二支撑面相贴合，第二支撑轴承9的内圈与驱动轴5相贴合。
优选地，转子3的内壁上设置有第一限位构件，驱动轴5的外壁上设置有与第一限位构件相配合的第二限位构件，转子3通过第一限位构件和第二限位构件驱动驱动轴5转动。其中，第一限位构件与转子3固定连接或者设置为一体，将第一限位构件与转子3固定连接便于零部件的安装、拆卸和更换，将第一限位构件与转子3设置为一体便于模具的一次成型。同理，第二限位构件与驱动轴5固定连接或者设置为一体，将第二限位构件与驱动轴5固定连接便于零部件的安装、拆卸和更换，将第二限位构件与驱动轴5设置为一体便于模具的一次成型。在一种可能的实施方式中，第一限位构件包括设置在转子3的内壁上并环形设置的多个第一凸起，第二限位构件包括设置在驱动轴5的外壁上并与第一凸起一一对应的多个第二凸起，通过第一凸起和第二凸起的相互配合实现转子3对驱动轴5的传动，第一凸起的长度方向和第二凸起的长度方向均可设置成沿驱动轴5的轴向设置。当然，第一限位构件和第二限位构件不限于上述的结构，本领域技术人员可以在实际应用中灵活地设置第一限位构件和第二限位构件的具体结构，只要通过第一限位构件和第二限位构件能够实现转子3对驱动轴5的传动即可，又或者，在实际应用中，还可以将转子3和驱动轴5设置成一体式结构，这种转子3和驱动轴5结构以及连接形式的改变并不偏离本发明的原理和范围。
优选地，转子3朝向后壳7的一侧设置有容纳部，定子4设置在容纳部内。其中，如图2所示，容纳部可以为圆形容纳部，即转子3朝向后壳7的一侧向内凹陷(具体为向前壳6的方向凹陷)形成圆形腔室，该圆形腔室能够将定子4全部容纳或者部分容纳，转子3和定子4构成磁回路，在转子3和定子4之间发生磁作用时，转子3可以相对定子4转动，从而驱动驱动轴5转动。
实施例二
基于背景技术指出的现有采用直驱电机的滚筒洗衣机由于直驱电机布置不合理，从而导致占用较多空间的问题，本发明提供了一种滚筒洗衣机，旨在使整机的容积增大，从而使滚筒洗衣机可以对更多的衣物进行洗涤，提升用户体验。
具体地，如图3和4所示，本发明的滚筒洗衣机包括滚筒，该滚筒包括外筒1以及设置在外筒1中的内筒2，滚筒洗衣机还包括与内筒2连接的直驱电机，直驱电机包括与外筒1相连的电机外壳和设置在电机外壳内的驱动组件，驱动组件包括转子3、定子4和驱动轴5，转子3和定子4均设置在电机外壳内，定子4固定在电机外壳上，转子3通过驱动轴5与内筒2连接。其中，定子4可以通过螺钉连接的方式固定到电机外壳上，当然，这并不是限制性的，本领域技术人员可以在实际应用中灵活地设置定子4与电机外壳的固定方式，只要能够通过电机外壳对定子4进行固定即可。
优选地，电机外壳包括相互连接的前壳6和后壳7，前壳6和驱动轴5之间设置有第一支撑轴承8，后壳7和驱动轴5之间设置有第二支撑轴承9。当然，还可以只在前壳6和驱动轴5之间设置支撑轴承，也可以只在后壳7和驱动轴5之间设置支撑轴承，本领域技术人员可以在实际应用中灵活地设置支撑轴承的数量和位置，只要通过支撑轴承能够对驱动轴5进行支撑即可。
需要说明的是，直驱电机一般安装在滚筒洗衣机滚筒的后侧，即安装在滚筒远离开门的一侧，因此在本发明的描述中，前壳6指的是电机外壳的靠近内筒2一侧的壳体，后壳7指的是电机外壳的远离内筒2一侧的壳体，在实际应用中，前壳6和后壳7可以通过螺钉连接等方式固定连接，还可以将前壳6和后壳7设置为一体，本领域技术人员可以在实际应用中灵活地设置前壳6和后壳7的设置以及连接方式，这种设置及连接方式的改变并不偏离本发明的原理和范围。
优选地，转子3设置在靠近前壳6的一侧，定子4设置在靠近后壳7的一侧。在实际应用中，可以在转子3朝向后壳7的一侧设置有容纳腔，定子4设置在容纳腔内。其中，如图3所示，容纳腔可以为圆形容纳腔，即转子3朝向后壳7的一侧向内凹陷(具体为向前壳6的方向凹陷)形成圆形腔室，该圆形腔室能够将定子4全部容纳或者部分容纳，转子3和定子4构成磁回路，在转子3和定子4之间发生磁作用时，转子3可以相对定子4转动，从而驱动驱动轴5转动。
优选地，前壳6、驱动轴5和外筒1之间形成间隙，间隙内设置有密封构件10。其中，密封构件10可以包括三个密封唇，三个密封 唇分别与前壳6、驱动轴5以及外筒1密封贴合，从而实现对前壳6、驱动轴5以及外筒1的密封。
优选地，外筒1向内凹陷形成容纳部，直驱电机的至少一部分设置在容纳部内。其中，直驱电机可以全部设置在容纳部内，也可以部分设置在容纳部内，本领域技术人员可以在实际应用中灵活地设置直驱电机设置在容纳部内一部分的体积，只要通过容纳部能够对直驱电机进行容纳即可，通过这样的设置，使得直驱电机和滚筒的结构更为紧凑，并且尽可能地降低整个滚筒的轴向长度，从而便于滚筒洗衣机内其他零部件的布置和安装。
进一步优选地，电机外壳远离内筒2的一侧基本与外筒1的后侧齐平，即后壳7的后侧与外筒1的后侧基本齐平，通过这样的设置，使得在从侧面观察滚筒时几乎无法看到电机外壳，从而使滚筒的结构更为紧凑，并且提高美观性。当然，在实际应用中，电机外壳还可以完全位于容纳部内或者微凸出于滚筒，本领域技术人员可以在实际应用中灵活地设置电机外壳相对于外筒1的布置位置。
优选地，驱动组件和内筒2之间还设置有支撑架11，支撑架11连接于内筒2上或者与内筒2设置为一体，将支撑架11与内筒2固定连接可以便于支撑架11的安装、拆卸、更换和维修，将支撑架11和内筒2设置为一体便于模具的一次成型，本领域技术人员可以在实际应用中灵活地设置支撑架11和内筒2之间的连接关系，只要通过支撑架11能够将内筒2和驱动组件中的驱动轴5连接即可。其中，支撑架11可以为三脚架、四脚架或者五脚架等，其中，以三脚架为例，通过三脚架的每个支脚可以对内筒2的后侧进行较好地支撑，提高内筒2的强度以及支撑效果，当然，支撑架11不限于上述示例的结构，还可以为其他结构，本领域技术人员可以在实际应用中灵活地设置支撑架11的具体结构，只要通过支撑架11能够对内筒2的后侧进行支撑并且实现与驱动轴5的连接即可。
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。
