Description

扫风组件、调风装置以及空调器 技术领域
本发明涉及空调器技术领域，具体而言，涉及一种扫风组件、调风装置以及空调器。
背景技术
为了对从空调器内吹出的风进行左右方向的角度调整，通常在空调器的出风口处设置有扫风组件。扫风组件的叶片是通过转动来实现左右扫风的，为了便于控制叶片的转动角度，需要设计一限位结构作为叶片转动的初始位置。同时，为了对从空调器内吹出的风进行高度方向的角度调整，通常在空调器的出风口处设置有导风组件，通过导风组件的摆动实现对风向的调整。
现有技术中有一种将扫风组件与导风组件连接的调风装置，在该装置中，在导风组件上设计有限位结构，通过此限位结构限定叶片的初始位置。但此方案存在一个缺陷：由于导风板是可以摆动的，故限位结构设计在运动的导风板上不容易限定叶片的初始位置，而且此种结构还导致控制叶片找到初始位置的程序也比较复杂。
发明内容
本发明提供一种扫风组件、调风装置以及空调器，以解决现有技术中扫风组件的叶片不易确定初始位置的问题。
为了解决上述问题，根据本发明的一个方面，本发明提供了一种扫风组件，包括：转轴，转轴上具有叶片；驱动装置，驱动装置包括固定部和设置在固定部上的驱动部，驱动部与转轴驱动连接，驱动部用于驱动转轴转动；第一限位件，设置在固定部上，第一限位件用于限定转轴在圆周方向的初始位置。
进一步地，扫风组件还包括：第二限位件，设置在转轴上，第二限位件能够与第一限位件接触以限定转轴在圆周方向的初始位置。
进一步地，第一限位件包括：第一连接段，凸出地设置在固定部上；第一延伸段，与第一连接段连接，第一延伸段沿转轴的轴向延伸，第一延伸段能够与第二限位件抵接。
进一步地，第二限位件包括：第二连接段，凸出地设置在转轴上；第二延伸段，与第二连接段连接，第二延伸段沿转轴的轴向延伸，第二延伸段能够与第一限位件抵接。
进一步地，固定部包括：壳体，驱动部至少部分地设置在壳体内；轴套，与壳体连接，第一限位件凸出地设置在轴套上，驱动部的驱动轴穿过轴套。
进一步地，驱动部的驱动轴上具有插槽，插槽内具有第一限位面，转轴的端部具有插头，插头上具有第二限位面，插头与插槽插接，第一限位面与第二限位面配合。
进一步地，插槽内具有多个第一限位面，插头的外侧具有多个第二限位面，多个第二限位面与多个第一限位面一一对应地配合连接。
进一步地，扫风组件还包括：卡扣，设置在转轴靠近驱动部的一端，驱动部的驱动轴上具有凸台，卡扣与凸台卡接以防止转轴相对驱动轴发生轴向移动。
进一步地，卡扣包括：悬臂，凸出地设置在转轴上；卡勾，与悬臂连接，卡勾与凸台卡接。
进一步地，卡扣还包括：手柄，手柄的一端与卡勾连接，手柄的另一端为自由端，手柄与卡勾分别位于悬臂的两侧。
根据本发明的另一方面，提供了一种调风装置，包括导风组件和扫风组件，扫风组件的转轴设置在导风组件上，其中，扫风组件为上述提供的扫风组件。
根据本发明的又一方面，提供了一种空调器，包括调风装置，调风装置为上述提供的调风装置。
应用本发明的技术方案，将扫风组件的第一限位件设置在驱动装置的固定部上，通过第一限位件限定转轴在圆周方向的初始位置。由于第一限位件位于固定不动的固定部上，因此第一限位件的位置固定不动，每当转轴转动到与第一限位件接触的位置时，转轴便有一个确定的已知位置，将该位置作为转轴以及叶片的初始位置，这样便于确定叶片的初始位置，进而便于对叶片的转动角度进行调整。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至图5所示，本发明的实施例提供了一种扫风组件，包括：转轴10，转轴10上具有叶片20；驱动装置，驱动装置包括固定部31和设置在固定部31上的驱动部，驱动部与转轴10驱动连接，驱动部用于驱动转轴10转动；第一限位件40，设置在固定部31上，第一限位件40用于限定转轴10在圆周方向的初始位置。
应用本实施例的技术方案，将扫风组件的第一限位件40设置在驱动装置的固定部31上，通过第一限位件40限定转轴10在圆周方向的初始位置。由于第一限位件40位于固定不动的固定部31上，因此第一限位件40的位置固定不动，每当转轴10转动到与第一限位件40接触的位置时，转轴10便有一个确定的已知位置，将该位置作为转轴10以及叶片20的初始位置，这样便于确定叶片20的初始位置，进而便于对叶片20的转动角度进行调整。而且，采用此种结构使得控制叶片20找到初始位置的程序也可以设置的比较简单。
这样不管空调器整机在开动时叶片20处于什么位置，都是需要从初始位置处开始转动计算，然后转动到所需要实现的预定角度处进行扫风。本实施例中的第一限位件40是不具有运动属性的静止参考物，极大方便了叶片20寻找初始位置，从而能够简化叶片20的控制程序，并实现叶片20的定角度扫风。
如图1和图2所示，扫风组件还包括：第二限位件50，设置在转轴10上，第二限位件50能够与第一限位件40接触以限定转轴10在圆周方向的初始位置。如此设置，当转轴10转动到一定位置时，第二限位件50可以与第一限位件40接触，以阻止转轴10继续转动，此位置作为转轴10以及叶片20的初始位置。这样当需要确定叶片20的初始位置时只需转动转轴10，当第二限位件50与第一限位件40接触时便可得到初始位置，这样便于确定叶片20的初始位置，从而便于对叶片20的转动角度进行调整。
具体地，如图3所示，第一限位件40包括：第一连接段41，凸出地设置在固定部31上；第一延伸段42，与第一连接段41连接，第一延伸段42沿转轴10的轴向延伸，第一延伸段42能够与第二限位件50抵接。如此设置能够便于第一限位件40与第二限位件50发生接触，从而便于确定转轴10和叶片20的初始位置。
如图4所示，第二限位件50包括：第二连接段51，凸出地设置在转轴10上；第二延伸段52，与第二连接段51连接，第二延伸段52沿转轴10的轴向延伸，第二延伸段52能够与 第一限位件40抵接。如此设置能够便于第一限位件40与第二限位件50发生接触，从而便于确定转轴10和叶片20的初始位置。具体地，在本实施例中，当转轴10转动到初始位置时，第一限位件40上的第一延伸段42与第二限位件50上的第二延伸段52接触，从而将转轴10限定在初始位置，确定初始位置之后就可便于对叶片20的转动角度进行调节。
如图3所示，固定部31包括：壳体31a，驱动部至少部分地设置在壳体31a内；轴套31b，与壳体31a连接，第一限位件40凸出地设置在轴套31b上，驱动部的驱动轴32穿过轴套31b。这样既便于第一限位件40的设置又能够对驱动部的驱动轴32进行避让。
在本实施例中，驱动部的驱动轴32上具有插槽32a，插槽32a内具有第一限位面，转轴10的端部具有插头11，插头11上具有第二限位面，插头11与插槽32a插接，第一限位面与第二限位面配合。如此设置可通过插接的方式实现转轴10与驱动轴32的连接，并且能够通过第一限位面与第二限位面的配合实现力矩的传递。因此，通过本实施例的技术方案能够便于转轴10与驱动轴32的装配。
具体地，在本实施例中，插槽32a内具有多个第一限位面，插头11的外侧具有多个第二限位面，多个第二限位面与多个第一限位面一一对应地配合连接。如此设置能够提高转轴10与驱动轴32连接的可靠性，防止两者发生相对转动，以更好地传递扭矩。例如，可以将插槽32a的截面与插头11的截面设置为相互匹配的六边形结构。
为了提高转轴10与驱动轴32的连接强度，在本实施例中，扫风组件还包括：卡扣60，设置在转轴10靠近驱动部的一端，驱动部的驱动轴32上具有凸台32b，卡扣60与凸台32b卡接以防止转轴10相对驱动轴32发生轴向移动。如此设置可通过卡扣60与凸台32b的卡接防止转轴10相对驱动轴32发生轴向移动，从而保证装置的可靠性。而且，卡接的连接方式便于装置的装配。
如图4所示，卡扣60包括：悬臂61，凸出地设置在转轴10上；卡勾62，与悬臂61连接，卡勾62与凸台32b卡接。这样能够留出足够的空间以便于卡扣60的设置。当卡勾62与凸台32b卡接后，凸台32b的连接部分位于悬臂61与卡勾62之间的区域内。
进一步地，卡扣60还包括：手柄63，手柄63的一端与卡勾62连接，手柄63的另一端为自由端，手柄63与卡勾62分别位于悬臂61的两侧。这样手柄63、臂61和卡勾62能够形成杠杆的效果，在操作时按压手柄63以使手柄63向靠近转轴10的方向移动，便可将卡勾62向远离转轴10的方向移动，这样可以使卡勾62有足够的避让空间以与凸台32b连接或分离。因此，通过本实施例的技术方案能够便于转轴10与驱动轴32的装配。
为了提高转轴10与驱动轴32的连接强度，在本实施例中，卡扣60设置为对称的两个，通过两个卡扣60分别与凸台32b连接。而且，在本实施例中，当卡勾62与凸台32b连接后，轴套31b也能够对卡勾62起到限位的作用。在本实施例中，卡扣60由弹性材料制成。例如，可将卡扣60与转轴10采用塑料材料一体注塑成型。
本发明的另一实施例还提供了一种调风装置，包括导风组件70和扫风组件，扫风组件的转轴10设置在导风组件70上，其中，扫风组件为上述实施例提供的扫风组件。应用本实施例的技术方案，将扫风组件的第一限位件40设置在驱动装置的固定部31上，通过第一限位件40限定转轴10在圆周方向的初始位置。由于第一限位件40位于固定不动的固定部31上，因此第一限位件40的位置固定不动，每当转轴10转动到与第一限位件40接触的位置时，转轴10便有一个确定的已知位置，将该位置作为转轴10以及叶片20的初始位置，这样便于确定叶片20的初始位置，进而便于对叶片20的转动角度进行调整。将调风装置设置为包括扫风组件和导风组件70，可以使用同一套装置实现对从空调器内吹出的风的左右方向和上下方向的调节，从而能够提高用户的舒适度并且能够使装置更加紧凑。
本发明的又一实施例提供了一种空调器，包括调风装置，调风装置为上述实施例提供的调风装置。通过使用该空调器，便于确定叶片20的初始位置，从而便于对叶片20的转动角度进行调整。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
