壁挂式空调器室内机的内部设置有贯流风扇以及电机，通常将贯流风扇的转轴的一端通过轴承连接在轴承座上，而将贯流风扇的转轴的另一端与电机的输出轴连接。
目前，为了实现贯流风扇的转轴与电机的输出轴之间的连接，一般会将电机的输出轴的连接端设置有扁平面，风扇的转轴的连接端形成轴套，在电机的输出轴的连接端伸入轴套中后，螺钉以螺纹连接的形式沿轴套的径向由外向内伸入轴套的内部并抵顶在输出轴的扁平面上。
但是，现有的上述贯流风扇与电机的连接方式存在贯流风扇的圆周方向质量不均匀导致转动时平衡性较差的问题，并且贯流风扇与电机的装配效率较低。
为了解决现有的贯流风扇与电机的连接方式存在贯流风扇的圆周方向质量不均匀导致转动时平衡性较差以及贯流风扇与电机的装配效率较低的问题，本实施例提供了一种如图1和图2所示的风扇组件及空调器室内机。
首先，在本实施例提供的一种风扇组件中，如图1和图2所示，该风扇组件包括贯流风扇1和电机2；贯流风扇1的连接转轴11沿其环向均匀地设置有多个第一限位部111，电机2的输出轴21沿其环向均匀地设置有与多个第一限位部111配合的多个第二限位部211；连接转轴11与输出轴21通过第一限位部111和第二限位部211进行插接配合。
示例性地，为了实现贯流风扇1的连接转轴11与电机2的输出轴21通过第一限位部111和第二限位部211进行插接配合的目的。如图1所示，可以将第一限位部111设置为凹槽，并将第二限位部211设置为凸块。这时，电机2的输出轴21可以插入贯流风扇1的连接转轴11的内部，并通 过该凹槽式的第一限位部111与凸块式的第二限位部211的配合实现连接转轴11与输出轴21的插接配合。
此外，为了实现连接转轴11与输出轴21通过第一限位部111和第二限位部211进行插接配合的目的。如图2所示，还可以将第一限位部111设置为凸块，与之对应的第二限位部211可以设置为凹槽。这时，贯流风扇1的连接转轴11可以插入输出轴21的内部，并通过该凸块式的第一限位部111与凹槽式的第二限位部211的配合实现连接转轴11与输出轴21的插接配合。
作为本实施例提供的上述风扇组件的一种优选的实施方式，对于凸块的形状和大小不作具体的限制，只要其能够实现本实施例的连接转轴11与输出轴21通过第一限位部111和第二限位部211进行插接配合，并能够保证贯流风扇1在其圆周方向上质量均匀以保证工作过程中具有较好的动平衡效果的目的即可。例如，凸块的宽度可以沿贯流风扇1的径向向外逐渐减小；或者，凸块的宽度也可以沿贯流风扇1的径向向外逐渐增大；或者，凸块的宽度还可以沿贯流风扇1的径向向外保持不变。于此同时，只需要凹槽的形状和大小与该凸块其相适应，均能够满足贯流风扇1的连接转轴11与电机2的输出轴21的插接配合的要求。
作为本实施例提供的上述风扇组件的一种优选的实施方式，贯流风扇1的连接转轴11除了可以为轴套或者轴杆之外，该连接转轴11还可以为贯流风扇1的轴向一端形成的连接孔，此时电机2的输出轴21可以插入该连接孔内实现与贯流风扇1的连接。可以理解的是，本实施例对贯流风扇1的连接转轴11作了扩大解释，但仍属于本实施例对贯流风扇1的连接转轴11的说明范围。
综上所述，在本实施例提供的一种风扇组件，贯流风扇1的连接转轴11沿其环向均匀地设置有多个第一限位部111，电机2的输出轴21沿其环向均匀地设置有与多个第一限位部111配合的多个第二限位部211，连接转轴11与输出轴21通过第一限位部111和第二限位部211进行插接配合。如此，能够保证贯流风扇1在其圆周方向上质量均匀以保证贯流风扇1在工作过程中具有较好的动平衡效果，同时极大的简化了贯流风扇1与电机2的连接方式，使得贯流风扇1和电机2拆卸和安装更加简单。
作为本实施例提供的上述风扇组件的一种优选的实施方式， 贯流风扇1的连接转轴11还沿其环向均匀地设置有多个第三限位部(图中未示出)，第一限位部111与第三限位部分别沿连接转轴11的长度方向间隔设置；电机2的输出轴21还沿其环向均匀地设置有与多个第三限位部配合的多个第四限位部(图中未示出)。
如此，通过在贯流风扇1的连接转轴11的不同长度位置处沿环向分别设置多个第一限位部111和多个第三限位部，来实现贯流风扇1的连接转轴11与电机2的输出轴21的插接，进一步提高了贯流风扇1和电机2之间连接的可靠性。
作为本实施例提供的上述风扇组件的一种优选的实施方式，可以将每个第三限位部均设置在相邻的两个第一限位部111的夹角之间，以使得贯流风扇1的连接转轴11与电机2的输出轴21之间的连接更可靠。
此外，还可以将第三限位部与第一限位部111沿连接转轴11的长度方向对应设置。同样能够实现本实施例的贯流风扇1的连接转轴11与电机2的输出轴21之间通过第一限位部111和第二限位部211进行插接配合的目的。
作为本实施例提供的上述风扇组件的一种优选的实施方式，第一限位部111和第二限位部211的大小和形状可以相同也可以不同。例如，第一限位部111为凹槽而第三限位部为凸块；或者，第一限位部111为凸块而第三限位部为凹槽；或者，第一限位部111和第三限位部均为凹槽；或者，第一限位部111和第三限位部均为凸块。
然后，本实施例还提供了一种空调器室内机，该空调器室内机的罩壳(图中未示出)中设置有以上任一实施方式中的风扇组件。
可以理解的是，由于在本实施例提供上述风扇组件中，贯流风扇1的连接转轴11沿其环向均匀地设置有多个第一限位部111，电机2的输出轴21沿其环向均匀地设置有与多个第一限位部111配合的多个第二限位部211，连接转轴11与输出轴21通过第一限位部111和第二限位部211进行插接配合。如此，能够保证贯流风扇1在其圆周方向上质量均匀以保证工作过程中具有较好的动平衡效果，同时极大的简化了贯流风扇1与电机2的连接方式，使得贯流风扇1和电机2拆卸和安装更加简单。同时，使得本实施例提供的空调器室内机能获得更好的用户体验。
作为本实施例提供的上述空调器室内机的一种优选的实施 方式，如图2所示，贯流风扇1的相对于连接转轴11的另一端的支撑转轴12上连接有轴承(图中未示出)。为了实现对贯流风扇1的支撑转轴12的位置的固定，可以在罩壳内的骨架(图中未示出)上设置有用于固定轴承的轴承座(图中未示出)，从而可以将该轴承安装在该轴承座内。
作为本实施例提供的上述空调器室内机的一种优选的实施方式，为了实现对电机2的固定安装，可以在罩壳内的骨架上设置有用于固定电机2的电机2安装座(图中未示出)。
当然，上述可以替换的实施方式之间、以及可以替换的实施方式和优选的实施方式之间还可以交叉配合使用，从而组合出新的实施方式以适用于更加具体的应用场景。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的保护范围之内并且形成不同的实施例。例如，在本发明的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
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。
