Description

空调器 技术领域
本发明涉及制冷领域，具体而言，涉及一种空调器。
背景技术
目前，空调室内机采用的离心风机的风叶直径较小。离心风机转动过程中，离心风机晃动小，不会出现离心风机撞击其他零部件情况。但是小直径风叶的离心风机会影响空调风量、性能。
随着人们对空调性能要求的提高，直径较小的风叶的离心风机已经不能满足人们的需求，因此需采用直径大的离心风机。如图1和图2所示，对于大直径风叶的离心风机20’的室内机而言，现有技术中通过电机带动并固定离心风机20’。如图2所示，为了避免离心风机与其他零部件发生干涉，离心风机20’的下表面与蒸发器30’之间具有距离H，该距离H大于等于8mm。由于离心风机直径大，将会造成离心风机的晃动量大，同时在重力作用下，离心风机有往下变形的趋势，进而会出现离心风机撞击其他零部件情况。
发明内容
本发明的主要目的在于提供一种空调器，以解决现有技术中的大直径离心风机不能稳定运行的问题。
为了实现上述目的，本发明提供了一种空调器，包括：壳体，具有进风口和出风口；离心风机，可转动地设置在壳体内，离心风机包括盘部及设置在盘部上的风叶；换热器，换热器设置在机壳内；滑动支撑部，设置在壳体内以对离心风机形成支撑。
进一步地，离心风机的轴线沿竖直方向延伸，换热器设置在风叶的周向内侧。
进一步地，滑动支撑部设置在换热器的顶部和盘部之间以使换热器对离心风机形成支撑。
进一步地，滑动支撑部包括第一支撑部和第二支撑部，第一支撑部设置在换热器上，第二支撑部设置在盘部上并与盘部同步运动。
进一步地，滑动支撑部还包括设置在第一支撑部上的多个滚动部，第二支撑部与滚动部接触。
进一步地，第一支撑部上设置有多个容纳孔，多个滚动部一一对应地安装在多个容纳孔内。
进一步地，第一支撑部为环形结构，多个容纳孔沿第一支撑部的周向布置。
进一步地，第二支撑部具有与滚动部配合的环形轨道。
进一步地，多个滚动部在第一支撑部上布置成多圈，环形轨道为与多圈适配的多个。
进一步地，滑动支撑部还包括连接件，第一支撑部通过连接件与换热器连接在一起。
进一步地，连接件包括框架及设置在框架上的缺口，框架套设在换热器外并通过紧固件与第一支撑部相连接。
进一步地，换热器呈环状。
进一步地，滑动支撑部包括第一支撑部和第二支撑部，第一支撑部设置在壳体上，第二支撑部设置在盘部上并与盘部同步运动。
进一步地，进风口设置在壳体的下部。
进一步地，出风口设置在壳体的周向侧壁上。
应用本发明的技术方案，空调器的壳体内可转动地设置有离心风机，离心风机包括盘部及设置在盘部上的风叶。当空调器工作时，由于离心风机的作用，风从壳体的进风口进风然后从壳体的出风口出风。在本申请中，在空调器的壳体内还设置有换热器，上述换热器能够起到换热作用，以使经过换热器的空气的温度发生变化。此外，空调器的壳体内还设置有滑动支撑部，以对离心风机形成支撑。这样，即使本申请中的离心风机的直径较大，由于滑动支撑部的支撑作用，因此离心风机的晃动可以被削减，离心风机也不会因为受到重力而产生向下变形的趋势。因此，本申请的技术方案有效地解决了现有技术中的大直径离心风机不能稳定运行的问题。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
如图3和图4所示，本实施例的空调器包括壳体10、离心风机20、换热器30以及滑动支撑部40，其中壳体10具有进风口11和出风口12；离心风机20可转动地设置在壳体10内，离心风机20包括盘部21及设置在盘部21上的风叶22；换热器30设置在风叶22的周向内侧；滑动支撑部40设置在换热器30的顶部和盘部21之间以使换热器30对离心风机20形成支撑。
应用本实施例的技术方案，空调器的壳体10内转动地设置有离心风机20，离心风机20包括盘部21及设置在盘部21上的风叶22。当空调器工作时，由于离心风机20的作用，风从壳体10的进风口11进风，然后从壳体10的出风口12出风。在本实施例中，空调器的壳体10内还设置有换热器30，上述换热器30能够起到换热作用，以使经过换热器30的空气的温度发生变化。此外，空调器的壳体10内还设置有滑动支撑部40，以对离心风机20形成支撑。这样，即使本实施例中的离心风机20的直径较大，由于滑动支撑部40具有支撑作用，因此离心风机20的晃动可以被削减，此外，离心风机20也不会因为受到重力而产生向下变形的趋势。因此，本实施例的技术方案有效地解决了现有技术中的大直径离心风机不能稳定运行的问题。
如图5所示，换热器30与壳体10之间通过多个钣金件相连接，上述结构简单、易于实现。在本实施例中，离心风机20由电机驱动，电机动力由盘部21的中心处输入。
如图3所示，在本实施例中，离心风机20的轴线沿竖直方向延伸，换热器30设置在风叶22的周向内侧。上述结构简单且可以使进入空调器的风换热更加均匀。
如图3和图4所示，在本实施例中，滑动支撑部40设置在换热器30的顶部和盘部21之间以使换热器30对离心风机20形成支撑。上述结构简单，易于实现，且上述结构将换热器30作为支撑结构的一部分，使得空调器的结构更加紧凑，减小了产品的体积，美化了产品的外观。
如图4所示，在本实施例中，滑动支撑部40包括第一支撑部41和第二支撑部42，第一支撑部41设置在换热器30上，第二支撑部42设置在盘部21上并与盘部21同步运动。上述 结构使得第一支撑部41与第二支撑部42之间能够相对运动，从而保证了空调器能够正常运转。同时，由于重力作用，在空调器工作时离心风机20有往下变形的趋势，因此位于盘部21上的第二支撑部42也将有向下变形的趋势。应用本实施例的技术方案，换热器30上具有第一支撑部41，其能够与第二支撑部42相配合，从而起到对第二支撑部42的支撑作用，即起到了对离心风机20的支撑作用，进而使得大直径离心风机20能够稳定、可靠地运行。
如图4所示，在本实施例中，第一支撑部41的上安装有多个滚动部43，第二支撑部42与滚动部43接触。首先，上述结构简单，通过设置滚动部43使得第一支撑部41与第二支撑部42之间产生滚动摩擦。由于滚动摩擦力小，因此使得第一支撑部41与第二支撑部42之间的相对转动变得更加容易，从而降低了第一支撑部41与第二支撑部42之间的磨损，进而保证了空调器的寿命。其次，在重力作用下，盘部21和盘部21上的第二支撑部42压紧多个滚动部43和第一支撑部41，从而起到了对离心风机20的支撑作用。优选地，上述滚动部43为滚珠，上述结构简单，易于实现。当然，本领域技术人员应当知道，滚动部43除了滚珠以外还可以为其他结构。具体地，滚动部还可以为滑轮。
下面以滚动部43为滚珠对本实施例进行说明，如图8和图9所示，在本实施例中，第一支撑部41上设置有多个容纳孔，多个滚珠一一对应地安装在多个容纳孔内。上述结构使得滚珠始终处于工作位置上，并且使得滚珠能够正常滚动工作。
如图5和图8所示，在本实施例中，第一支撑部41为环形结构，多个容纳孔沿第一支撑部41的周向布置。上述结构简单、易于实现。
如图5和图10所示，在本实施例中，第二支撑部42具有与滚珠配合的环形轨道。上述结构使得滚珠始终处于工作位置上，保证了第一支撑部41与第二支撑部42之间能够相对转动。并且由于滚珠与第二支撑部42上的环形轨道配合，使得整个空调器的结构更加紧凑。
如图8至图10所示，在本实施例中，多个滚珠在第一支撑部41上布置成多圈，环形轨道为与多圈适配的多个。上述结构使得第一支撑部41与第二支撑部42之间能够更好地相对转动，同时也能够更好地支撑离心风机20。
如图6和图7所示，在本实施例中，空调器还包括连接件44，第一支撑部41通过连接件44与换热器30连接在一起。上述结构简单，易于实现。
如图6和图7所示，在本实施例中，连接件44包括套设在换热器30外的框架以及设置在框架上的缺口，上述缺口使得框架更易套设在换热器30上。当框架套设在换热器30上时，可以通过紧固件将连接件44与第一支撑部41相连接，从而使得第一支撑部41固定在换热器30上。优选地，上述紧固件可以为螺钉，在框架的缺口周围以及第一支撑部41上设置有与上述螺钉相适配的螺孔。当然，本领域技术人员应当知道，上述框架的形状不限，在本实施例中，框架为矩形框。
如图3和图4所示，在本实施例中，换热器30呈环状。上述结构能够充分利用换热器30进行换热。当然，可以根据制冷或制热的需要把换热器30设置为沿其径向方向上的多层。需要换热的空气经过多层换热器，使得空气的换热更充分。
在图中未示出的实施例中，滑动支撑部40包括第一支撑部41和第二支撑部42，第一支撑部41设置在壳体10上，第二支撑部42设置在盘部21上并与盘部21同步运动。上述结构简单、易于实现。
如图3所示，在本实施例中，进风口11设置在壳体10的下部。空气从壳体10的下部的进风口11进入空调器，通过换热器30再排出空调器。具体地，进风口11的中心位置位于离心风机20的转动轴线上。这样空气从离心风机20的中心进入，上述结构保证了进风和出风的风量和出风的温度更加均匀。
如图3所示，在本实施例中，出风口12设置在壳体10的周向侧壁上。上述结构充分利用了空调器的空间，使得空调器的结构紧凑。具体地，出风口12呈环状。这样空调器可以实现360度的出风，空调器保证了室内各处温度均匀升温或降温。
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。
