参见图1至图20所示，根据本申请的实施例，提供了一种空调器，本实施例中的空调器包括风道部件。
参见图1至图8所示，本实施例中的风道部件包括风道本体10以及风叶组件20。其中，风道本体10上设置流通通道121；多个风叶组件20设置在流通通道121内并沿流通通道121的轴向间隔设置，多个风叶组件20中的一个位于风道本体10的第一端并凸出于风道本体10第一端的端面123。
实际工作时，在下进风上出风模式下，本实施例中的风叶组件20可沿顺时针方向转动，气流从流通通道121的第一端向第二端方向流动；在上进风下出风模式下，风叶组件20在流通通道121内沿顺时针方向旋转，气流从流通通道121的第二端向第一端方向流动。通过多个风叶组件20的作用，能够增加风道部件的风量，同时起到多次增压的效果。
由于本申请的中的风道本体10第一端处具有凸出于风道本体10第一端的端面123的风叶组件20，即风叶组件20部分露出风道本体10外部，在下进风上出风模式时，风道本体10第一端的风叶组件20同时具有轴向吸风和侧向(径向)吸风作用，加大风叶组件20做功能力，提高风叶组件20效率；在上进风下出风模式时，风道本体10第一端的风叶组件20可以将部分气流提前甩出风道，风道本体10内部阻力减小，做功效率大幅度提高。
在一些实施例中，本实施例中的端面123垂直流通通道121的轴线，结构简单，稳定可靠。当然，在本申请的其他实施例中，还可以将端面123设置为倾斜于流通通道121的轴线的方式。
本实施例中的风道部件还包括驱动组件30，该驱动组件30与风叶组件20驱动连接以驱动风叶组件20沿顺时针方向转动或者沿逆时针方向转动，便于使得风道部件在上进风下出风模式和下进风和上出风模式之间的切换。
为了便于对驱动组件30进行安装，本实施例中的风道部件还包括安装板40，该安装板40穿过流通通道121，驱动组件30安装在安装板40上。
在一些实施例中，本实施例中的驱动组件30为驱动电机，实际安装时，将风叶组件20安装在驱动电机的输出轴31上，通过驱动电机的正转和反转，驱动风叶组件20沿顺时针方向旋转或者沿逆时针方向旋转，进而使得风道部件在上进风下出风模式和下进风和上出风模式之间的切换。
安装板40上设置有导流罩41，驱动组件30位于导流罩41的内部，通过导流罩41的作用，便于对驱动电机进行保护，还能够起到导流和整流气流的作用。
本实施例中的导流罩41呈喇叭状结构设置，喇叭状结构开口较大的一端朝向流通通道121的第二端设置，导流罩41的外周具有环形通道42，便于流体通过，该环形通道42内设置有整流组件，便于对流通通道121内的气流进行整流。
本实施例中的整流组件包括多块整流叶片43，多块整流叶片43沿环形通道42周向均匀布置，便于对流通通道121内的气流进行整流，增加流通通道121内的导叶面积，减少能量损耗。
参见图1至图9所示，本实施例中的风道部件还包括导流组件50，该导流组件50设置在流通通道121第二端处，可以将气流方向从周向运动转为轴向运动，减少气流间涡流损失，提高风机效率。
参见图9所示，本实施例中的导流组件50包括定位柱51和多块导叶52，多块导叶52沿定位柱51的外周间隔布置，且导叶52远离定位柱51的一端固定在风道本体10上，结构简单，稳定可靠。
参见图10至11所示，在本申请的一些实施例中，风叶组件20包括定位套21和多块风叶22，多块风叶22沿定位套21的外周间隔均匀布置。
参见图12和图13所示，在本申请的另一些实施例中，风叶组件20的结构与图10和图11的基本相同，所不同的是，本实施例中的风叶组件20还包括分流叶片23，分流叶片23固定在定位套21的外侧壁上并位于相邻两块风叶22之间。
参见图1至图9所示，本实施例中的风道本体10包括第一风道本体11和第二风道本体12，其中，第一风道本体11上的流通通道121的中间段设置有内凹缩口111，多个风叶组件20分别位于内凹缩口111的两侧，多个风叶组件20中一个的端部凸出于内凹缩口111处；第二风道本体12上的流通通道121的中间段的横截面积沿轴向不发生变化，风叶组件20位于中间段内；第一风道本体11和第二风道本体12可切换地套设在风叶组件20、风叶组件20、安装板40、驱动组件30、导流组件50的外周。
需要说明的是，本实施例中的流通通道121的中间段是指流通通道121的位于导流组件50与风道本体10第一端的风叶组件20之间的间隔段。
实际工作时，本实施例中的第一风道本体11和第二风道本体12是可切换地套设在风叶组件20、风叶组件20、安装板40、驱动组件30、导流组件50的外周，能够适应不同的出风需求。具体来说，本实施例中的第一风道本体11尤其适用于下进风上出风模式，第二风道本体12尤其适用于上进风下出风模式。
第一风道本体11内距离内凹缩口111最近一个风叶组件20与流通通道121第一端的间距小于内凹缩口111与流通通道121第一端的间距。也就是说，本实施例中的第一风道本体11的内凹缩口111的位置位于顶端的风叶组件20底端上方(见附图2)，使得顶端的风叶组件20可以同时具有轴向吸风和侧向(径向)吸风作用，同时加大次级风道二次做功能力，提高风叶组件20效率，效果十分显著。
在一些实施例中，本实施例中的风叶组件20为两个，两个风叶组件20的摆放方式相同，两个风叶组件20分别位于安装板40的两侧。当然，在本申请的其他实施例中，还可以将风叶组件20设置为三个或者三个以上。
本实施例中的两个风叶组件20的摆放方式相同，这里的意思是指：风道本体10内的两个风叶组件20的放置方式一样，即两个风叶组件20上的风叶22的旋向一致，且风叶组件20的外径大的一端靠近风道本体10的第二端设置，风叶组件20的外径较小的一端靠近风道本体10的第一端设置的方式，这种方式可以增大风叶组件20做功能力。
再次结合图1至图20所示，本实施例中的风道部件为一种两级混流风道，实际工作时，该风道部件可以实现气流进、出口方向的切换，以实现上进下出或者下进上出两种送风模式。图2以及图4分别为本申请的风道部件的上下两种出风模式，本实施例中的风叶组件20的风叶组件20的叶片宽大、无外封闭圈，有带分流叶片23和不带分流叶片23两种形式，风叶组件20做功过程可以实现轴向和离心方向两种效果。该风叶组件20搭配图2和图4所示的第一风道本体11和第二风道本体12，可实现上进下出或者下进上出两种送风模式。
制冷模式时，空调器采用下进上出的送风模式，如图2所示，沿风道部件的俯视图来看，此时两级风叶组件20均逆时针方向旋转。气流从底部的风叶组件20下端进入，从底部的风叶组件20吹出后，经过带整流叶片43的安装板40，该安装板40在满足固定驱动电机功能的同时可将从底部的风叶组件20吹出的气流进行整流，将气流的周向运动转化成轴向运动，以减少气流间涡流损失，经过整流后的气流由底部的风叶组件20下端进入流通通道121，经过上端的风叶组件20二次做功后，从上端的风叶组件20上端吹出后经过导流组件50进行二次整流后吹出风道本体10，从而实现下进上出的送风模式，气流在风叶组件20内部的流向见图19所示。
制热模式时，空调器采用上进下出的送风模式，如图3所示，沿风道部件的俯视图来看，此时两级风叶组件20均沿顺时针方向旋转。气流从顶端的进入流通通道121后，首先经过导流组件50，此时导流组件50起到进口预选和整流的双重作用，之后经过上端的风叶组件20做功后，经过带整流叶片43的安装板40，整流叶片43可将从上端的风叶组件20吹出的气流进行整流，将气流的周向运动转化成轴向运动，以减少气流间涡流损失，经过整流后的气流 由底端风叶组件20上端进入，经过底端风叶组件20二次做功后，最终从底端风叶组件20下端吹出风道本体10，实现上进下出的送风模式，气流在风叶组件20内部的流向见图20所示。
实际安装时，两个风叶组件20分别位于安装板40的两端，该安装板40在满足固定驱动电机功能的同时，可以起到风叶组件20间气流整流效果，安装板40上的导流罩41与整流叶片43连接，此结构可以对气流起到导向作用，使得气流都向整流叶片43处汇集，同时也增大了风道本体10内的导叶的面积，减少了能量损耗。上端的导流组件50上的导叶52可以在两种模式下分别起到出口整流和进口预选的效果。安装板40上的整流叶片43可以将气流方向从周向运动转为轴向运动，减少气流间涡流损失，极大地提高风机效率，增大出风量。
本申请中的风道部件可以实现风叶组件20的二次做功过程，这种方式可以加大整个风叶组件20的做功能力。以下进上出为例，底端的风叶组件20做功后，经过带整流叶片43的安装板40进行整流，可以减少气流间涡流损失，之后再经过顶端的风叶组件20二次做功，可以极大的提高风叶组件20的做功能力，且可以起到二次增压的效果。因此，该风道部件可以极大的提高出风量，降低风机能量损耗，同时起到较大增压效果，可以克服更大的阻力，应用到上进下出或者下进上出两种送风模式的空调上，具有显著效果。
当然，在本申请的其他实施例中，风道部件不限于使用在空调器中，也不限于制热模式或者是制冷模式的使用，只要是需要使用本申请的风道部件的其他结构，均在本申请的保护范围内。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
(1)本申请的风道部件可以实现气流进、出口方向的切换。
(2)本申请的风道部件可以极大地增加风量,，同时起到二次增压的效果。
(3)本申请的带整流组件的安装板减少气流间涡流损失，提高风叶组件效率。将安装板与整流组件相结合，可以使其在满足电机安装固定的同时起到对气流的整流效果。安装板下部的导流罩与整流组件连接，可以对气流起到导向作用，增大导叶面积，减少能量损耗。
(4)本申请中的两级风道间内凹缩口处位置置于顶端风叶组件底端上方，使得顶端风叶组件可以同时具有轴向吸风和侧向(径向)吸风作用，同时加大次级风道二次做功能力，提高风叶组件效率。
(5)本申请的风叶组件部分露出风道本体外部，在下进风上出风模式时，风道本体第一端的风叶组件同时具有轴向吸风和侧向(径向)吸风作用，加大风叶组件做功能力，提高风叶组件效率；在上进风下出风模式时，风道本体第一端的风叶组件可以将部分气流提前甩出风道，风道本体内部阻力减小，做功效率大幅度提高。
