所述筒体整体为正三棱柱状，且其转动轴线平行于三棱柱的中心轴线，所述筒体的一个侧壁朝向所述出风口，另一侧壁朝前并竖立于所述壳体的前面板下方，以构成所述壳体的前部外观，剩余一个侧壁朝向后下方。
可选地，所述筒体未构成所述通风区段的侧壁上开设有多个散风孔，以允许所述筒体内的部分气流经所述多个散风孔向外扩散。
可选地，所述导风装置还包括至少一个导风板，其设置在所述筒体内，用于将从一个通风区段流入所述筒体的气流主体部分导向另一所述通风区段。
可选地，每个所述导风板为沿弯曲状，以使其两端切线分别垂直于所述两个通风区段。
可选地，所述导风板的数量为多个，其沿所述导风板的厚度方向依次间隔排列；且
多个所述导风板的一端固定连接于一个固定轴，另一端均固定连接于另一固定轴，两个所述固定轴分别固定于所述筒体的两个端壁。
可选地，所述导风装置还包括两个端盖，两个所述端盖固定于所述壳体，且位于所述筒体两端的外侧；
至少一个所述端盖内设置有电机，所述电机的转轴连接所述筒体的端壁，以驱动所述筒体转动。
可选地，所述壳体为横向设置的长条状，其内设置有用于输送气流的风道，所述风道的出口连接所述出风口；且
所述筒体的长度方向平行于所述壳体的长度方向，并且所述筒体贴靠在所述壳体外侧。
本发明的壁挂式空调室内机中，导风装置包括可转动的筒体，筒体有至少两个通风区段。壳体出风口的出风气流并非直接吹向室内环境，而是先经某通风区段进入筒体，在筒体内腔短暂聚集后，再经筒体的其他通风区段向外吹出。如此，可通过转动筒体切换不同的通风区段与出风口相对，利用不同的通风区段用于朝室内送风，最终达到改变送风效果的目的。例如，可使不同通风区段在处于送风位置时的朝向、出风面积等参数不同，以便其送风时的风向、风量不同，结构非常新颖、巧妙。
进一步地，本发明的壁挂式空调室内机中，使筒体为三棱柱状并使其两个侧壁构成两个通风区段，恰好利用一个通风区段朝前送风，以便满足制冷模式的需要，利用另一通风区段朝下送风，满足制热模式的需要。此外，可进一步使三棱柱筒体的第三个侧壁上开设多个散风孔，使筒体内部的少部分气流通过散风孔向外慢慢扩散，使壁挂式空调室内机整体的送风角度范围更大，避免因长期朝向一个方向导风导致室内各处温差太大。
进一步地，本发明的壁挂式空调室内机中，导风板设置在筒体内。当出风气流经一个通风区段进入筒体后，导风板将气流的主体部分顺畅地引导至另一通风区段，减少气流在筒体内的盘旋，减少风力损耗。

本发明实施例提供了一种壁挂式空调室内机。壁挂式空调室内机为分体壁挂式房间空调器的室内部分，用于调节室内空气，例如制冷/制热、除湿、引入新风等等。
图1是本发明一个实施例的壁挂式空调室内机的结构示意图；图2是图1所示壁挂式空调室内机的示意性前视图；图3是图2的A-A剖视放大图；图4是图3所示壁挂式空调室内机在导风装置改变送风方向后的示意图。图中用箭头示意了气流的流动方向。
如图1至图4所示，本发明实施例的壁挂式空调室内机一般性地可包括壳体10和导风装置20。
壳体10限定有用于容纳壁挂式空调室内机的各部件的容纳空间，壳体10内部形成用于调节室内环境的气流。例如制冷模式下的冷风、制热模式下的热风以及新风模式下的新风气流等等。壳体10开设有出风口12，用于引出壳体10内的气流。
导风装置20设置在出风口12的外侧。导风装置20包括筒体21，筒体21为中空结构，内部具有空腔。筒体21的周壁包括沿其周向排列的至少两个通风区段，例如图3所示，可使筒体21仅具有两个通风区段211、212。当然，也可设置更多的通风区段。筒体21可受控转动，以在转动至使某一通风区段与出风口12相对的位置时，使出风口12的出风气流经该通风区段进入筒体21的内腔，然后经其他通风区段吹向室内环境。需要注意的是，“某一通风区段”并非特定的一个通风区段，本实施例中全部或者至少部分(至少两个)通风区段都能用于与出风口12相对，而具体启用哪个通风区段与出风口12相对是可选的。
如此，出风口12的出风气流并非直接吹向室内环境，而是先经某通风区段进入筒体21，在筒体21内腔短暂聚集后，再经筒体21的其他通风区段向外吹出。如此，可通过转动筒体21切换不同的通风区段与出风口12相对，以利用不同的通风区段用于朝室内送风，最终达到改变送风效果的目的。例如，可使不同通风区段在处于送风位置时的朝向、出风面积等参数不同，以便其送风时的风向、风量不同。
具体地，例如图2和图3所示，可使筒体21包括两个通风区段211、212，如图3所示，可使通风区段211与出风口12相对以用于进风，使通风区段212用于送风，通风区段212用于送风时，送风方向是朝下的。需要转换送风方向时，可将筒体21逆时针转动120°至图4状态，使通风区段212与出风口12相对以用于进风，使通风区段211用于送风，通风区段211用于送风时，送风方向是朝前的。可见，本实施例通过启用不同的通风区段进行送风，改变了送风方向。当然，也可使两个通风区段211、212的出风面积不同，以便通过启用不同的通风区段进行送风来改变出风量。
如图1和图2所示，对于壁挂式空调室内机而言，壳体10通常为横向设置的长条状，也就是壳体10的长度方向平行于水平横向。壳体10内设置有用于输送气流的风道60，风道60由前后间隔设置的风道壁61、62限定出，风道60的出口连接出风口12。与之相匹配地，筒体21的长度方向沿平行于壳体10的长度方向，并且筒体21贴靠在壳体10的外侧，且使某个通风区段211位于风道60的出口处。如图3所示，通风区段211可形成有出风格栅2110，通风区段212可形成有出风格栅2122，以使筒体21的结构更加稳固，且起到防护作用。出风格栅可包括多个平行间隔设置的格栅条。各个格 栅条可固定于筒体21的主体部分，如图6。当然，也可使各格栅条可转动地安装于筒体21的主体部分，以便可转动地开闭出风格栅2122以及引导出风格栅2122的出风方向。
当然，也可使通风区段211、212不设置格栅，直接为常规的开口，使气流更加顺畅地流进/流出筒体21。
在一些实施例中，可使筒体21整体为棱柱状，其多个侧壁中的至少部分侧壁构成通风区段。棱柱具有多个侧壁和轴向的两个端壁。例如，三棱柱具有三个侧壁，四棱柱具有四个侧壁。多个侧壁中的至少部分侧壁构成通风区段。
图5是导风装置的分解示意图，图6是图5的D处放大图。
如图1至图6所示，可使筒体21整体为三棱柱状，其三个侧壁(也即是三棱柱的三个侧面)中的两个构成两个通风区段211、212。并且，筒体21配置成在一个通风区段211用于送风时，使该通风区段211朝向前方，也就是使三棱柱该侧壁的外表面朝前，以便前送风，如图4。在另一个通风区段212用于送风时，使该通风区段212朝向下方，也就是使三棱柱该侧壁的外表面朝下，以便朝下送风，如图4。此处的朝前和朝下并未严格限定为水平朝前，竖直朝下，也包括斜向前、斜向下。在制冷模式时利用通风区段211朝前送风，如图4，使冷风流动距离更远，并逐渐向下扩散，使得冷空气覆盖范围更大。在制热模式下主要利用通风区段211朝下送风，使暖风气流能更好地抵达地面，实现暖足体验。在一些替代性的实施例中，筒体也可为四棱柱、五棱柱等多棱柱，以便设计更多的通风区段。或者，筒体也可为圆柱状、椭圆柱状等形状，当然筒体也可以为其他不规则的形状。
进一步地，如图1至图6所示，可使出风口12开设于壳体10的前侧下部，以朝前下方敞开。使筒体21整体为正三棱柱状，即任意相邻的两个侧壁的夹角为60°，且其转动轴线平行于三棱柱的中心轴线，筒体21的一个侧壁朝向出风口12，另一侧壁朝前并竖立于壳体10的前面板101下方，以构成壳体10的前部外观，剩余一个侧壁朝向后下方。例如图3，当通风区段211所在侧壁朝出风口12时，侧壁213朝前，通风区段212所在侧壁朝向后下下方。
如此，当制热模式下利用通风区段212朝下送风时，通风区段212是朝向后下方的，如图4，热风吹向壁挂式空调室内机所在的墙壁，并沿墙壁更 加顺畅地向下流动，在流动过程中形成附壁效应，能沿着墙壁更好地抵达地面。现有一些改进方案大多选择将出风气流竖直向下引导，以解决热风不易下沉的问题。而本实施例则使气流朝墙壁吹出，利用附壁效应使气流更好地下沉流动，结构更加巧妙。当然，在一些替代性实施例中，也可使三棱柱的横截面为非等边的等腰三角形。
在一些实施例中，如图1至图6所示，可使筒体21未构成通风区段的侧壁213上开设有多个散风孔2131，以允许筒体21内的部分气流经多个散风孔2131向外扩散，使壁挂式空调室内机整体的送风角度范围更大，避免因长期朝向一个方向导风导致室内各处温差太大。散风孔2131可为圆孔、方孔、腰型孔或其他形状的孔。各个散风孔2131可在侧壁213上沿矩阵式排列。当然，也可采用其他方式排列。各个散风孔2131的大小和形状可以相同，也可以不同。
在一些实施例中，如图3至图6所示，导风装置20还包括至少一个导风板22，导风板22设置在筒体21内，用于将从一个通风区段流入筒体21的气流主体部分导向另一通风区段。可使每个导风板22为长度方向平行于筒体21轴向的长条状。在图3所示状态，导风板22的a端朝向通风区段211，b端朝向通风区段212，以便将出风气流从通风区段211导向通风区段212。而当筒体21转动至图4状态后，通风区段212用于进风，通风区段211用于送风，导风板22将出风气流从b端导向a端。由于设置了导风板22，减少了气流在筒体21内的盘旋，减少风力损耗。当然，并非全部气流都会受到导风板22的引导，仍有少部分距导风板22较远，受导风板22引导较弱或受导风板22引导的气流将从散风孔2131处向外吹出。
在一些实施例中，导风板22的数量为多个，以便更有力地引导气流，如图3至图7所示，导风板22的数量为3个。图7是图5的E处放大图。多个导风板22沿导风板的厚度方向依次间隔排列。多个导风板22的一端固定连接于一个固定轴224，另一端均固定连接于另一固定轴224，且两个固定轴224分别固定于筒体21的两个端壁214，以使导风板22能随筒体21转动。筒体21的两个端壁214与其侧壁之间可以为独立部件，通过过盈配合、卡接或其他方式连接装配。
在一些实施例中，请参考图3和图4，可使每个导风板22为弯曲状，以使其两端切线分别垂直于两个通风区段211、212。可以理解的是，使导风板 22与通风区段211、212垂直，气流会更顺畅地流向/流出导风板22。如图3所示，由于通风区段211与两个通风区段211、212均夹持锐角(图示实施例为60°)，如果导风板22为平板，将无法同时与两个通风区段211、212垂直，这将使气流流动不畅。为解决这一问题，本实施例特别使导风板22为弯曲状，例如图3，使导风板22沿气流方向为圆心角约为60°的弧形，以便其两端的切线分别与通风区段211、212垂直。
在一些实施例中，如图1和图5所示，导风装置20包括两个端盖23，两个端盖23固定于壳体10，且分别位于筒体21的两端的外侧。例如，端盖23上可设置有凸起部2312，凸起部2312用于嵌入壳体10开设的凹腔内，以定位于壳体10，然后可通过螺钉或其他方式进行连接紧固。
至少一个端盖23内设置有电机24，电机24的转轴连接筒体21的端壁214，以驱动筒体21转动。可如图5所示，使两个端盖23内均设置电机24。
具体地，端盖23可包括一侧敞开的端盖本体231和用于封盖端盖本体231的盖体232。端盖本体231开设有通孔2314，电机24安装于端盖本体231内，然后由盖体232封盖住端盖本体231。电机24的轴通过通孔2314伸出端盖23之外，以驱动筒体21的端壁214。例如图5和图7所示，还可使导风板22的固定轴224穿透端壁214，由固定轴224与电机24的转轴连接。
如图3所示，本发明实施例中，壁挂式空调室内机可为利用蒸气压缩制冷循环系统进行制冷/制热的分体壁挂式房间空调器的室内部分。壳体10的内部设有换热器30和风机40。换热器30、节流装置与设置于空调室外机内的压缩机、冷凝器以及其他的制冷元件通过管路相连接，构成一蒸气压缩制冷循环系统。在风机40的作用下，室内空气经壳体10顶部的进风口11进入壳体10的内部，与换热器30完成强制对流换热后，形成热交换风，然后再在风道60的引导下吹向风道60的出口，然后进入筒体21。风机40优选为贯流风机，其设置在风道60的进口处。换热器30优选为三段式换热器。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
