可选地，立式空调室内机还包括：至少一个齿轮齿条机构，用于驱动导风体上下平移，每个齿轮齿条机构包括电机、相互啮合的齿轮和齿条，电机安装于机壳，齿轮连接于电机，齿条沿竖直方向延伸且连接于导风体。
可选地，出风口位于机壳前侧上部区域，机壳的后侧下部开设有进风口；且立式空调室内机还包括离心风机和板状换热器，离心风机设置在进风口前侧且轴线沿前后方向延伸，板状换热器从上至下逐渐向前倾斜地设置在机壳内的上部区域内。
本发明的立式空调室内机中，机壳出风口处设置有可动的导风体，导风体具有上吹位置和下吹位置，从而使立式空调室内机具有上吹模式和下吹模式以供选择，可提升制冷和制热效果。例如，当空调制热需要运行下吹模式时，可使导风体运动至下吹位置，使其与机壳限定出下出风通道，引导送风气流紧贴着机壳外周面向下流动，流出下出风通道后，依靠附壁效应继续沿机壳外周面向下流动，以便顺利到达地面，形成地毯式送风效果。同理，当空调制冷运行上吹模式时，使导风体运动至上吹位置，使其与机壳限定出上出风通道，引导送风气流紧贴着机壳外周面向上流动，流出上出风通道后，依靠附壁效应继续沿机壳外周面向上流动，以便顺利到达屋顶。本发明的立式空调室内机的制冷或制热效果更好，也能避免冷风或热风吹人导致人体不适。
进一步地，本发明的立式空调室内机中，设计了一个可上下平移的导风体，使其上下表面与出风口上下壁形成上下出风通道，结构非常简单巧妙。而且，模式切换动作也非常简单、可靠。此外，本发明进一步使导风体上下表面为内凹弧面，以便引导送风气流更加竖直地向上或向下流动，以更好地贴合于机壳外周面，使附壁效应更好。
进一步地，本发明的立式空调室内机中，使导风体在处于上吹位置时，使其下表面贴合于出风口下壁，可增强密封性，避免送风气流从导风体与出风口下壁之间泄漏而影响上吹效果。而且，也使导风体与机壳相接为一体，使空调外形更加美观。同理，导风体处于下吹位置，使其下表面贴合于出风口上壁，以增强密封性，避免气流泄漏。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：

具体实施方式
下面参照图1至图6来描述本发明实施例的立式空调室内机。其中，“前”、“后”、“上”、“下”、“顶”、“底”、“内”、“外”、“横向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。图中用箭头示意了送风气流的流动方向。
本发明实施例提供了一种立式空调室内机，用于调节室内空气，例如制冷/制热、除湿、引入新风等等。
图1是根据本发明一个实施例的立式空调室内机的示意性前视图；图2是图1所示立式空调室内机的示意性俯视图；图3是图1所示立式空调室内机的示意性剖视图；图4是将图3所示立式空调室内机的导风体20移动至上吹位置时的示意图；图5是将图3所示立式空调室内机的导风体20移动 至下吹位置时的示意图。
如图1至图5所示，本发明实施例的立式空调室内机一般性地可包括机壳10和导风体20。机壳10上开设有进风口11和出风口12，进风口11用于吸入室内空气，出风口12用于将机壳10内的送风气流排向室内。该送风气流可为立式空调室内机在制冷模式下制取的冷风，在制热模式下制取的热风，或者在新风模式下引入的新风等等。
导风体20可动地设置在出风口12处，并配置成：可运动至一上吹位置，以与机壳10共同限定出朝上敞开的上出风通道251，用于引导从出风口12流出的送风气流沿机壳10的外周面向上流动，如图4。或者，导风体20运动至一下吹位置，以与机壳10共同限定出朝下敞开的下出风通道252，用于引导从出风口12流出的送风气流沿机壳10的外周面向下流动，如图5。
本发明实施例的立式空调室内机具有上吹模式和下吹模式以供选择，可提升制冷和制热效果。例如，当空调制热需要运行下吹模式时，可使导风体20运动至下吹位置，使其与机壳10限定出下出风通道252，以便引导送风气流紧贴着机壳10的外周面向下流动。送风气流流出下出风通道252后，依靠附壁效应继续沿机壳10的外周面向下流动，以便顺利到达地面，形成地毯式送风效果，如图5。同理，当空调制冷运行上吹模式时，使导风体20运动至上吹位置，使其与机壳10限定出上出风通道251，引导送风气流紧贴着机壳10的外周面向上流动。送风气流流出上出风通道251后，依靠附壁效应继续沿机壳10外周面向上流动，以便顺利到达屋顶，如图4。本发明实施例的立式空调室内机的制冷或制热效果更好，也能避免冷风或热风吹人导致人体不适。
可使送风气流流经的机壳10的外周面区域为平坦表面，以利于送风气流更好地贴合着机壳10的外周面流动。
在一些实施例中，如图1至图5所示，可使导风体20可上下平移地设置在出风口12处，以便向下移动至上吹位置，使其上表面21与出风口12的上壁121形成上出风通道251，如图4。或者，导风体20向上移动至下吹位置，使其下表面22与出风口12的下壁122形成下出风通道252，如图5。
本发明实施例仅通过上下移动导风体20便可完成其出风模式的切换，结构非常简单巧妙。而且，模式切换动作也非常简单、可靠。
本实施例中，导风体20可运动至处于上吹位置和下吹位置之间的中间 位置，以大致封闭出风口12，如图1和图3。立式空调处于关机状态时候，可使导风体20处于中间位置。
在一些实施例中，如图3至图5所示，可使导风体20的上表面21包括从机壳10内侧向外侧方向逐渐向上倾斜延伸的内凹弧面，以便空调运行上吹模式时，使气流经过内凹弧面的引导，可更加竖直地向上吹出，以更好地贴合于机壳10的外周面，使附壁效应更好。同理，使导风体20的下表面22包括从机壳10内侧向外侧方向逐渐向下倾斜延伸的内凹弧面，在空调运行下吹模式时，使气流经内凹弧面的引导，更加竖直地向下吹出。
此外，如图3至图5所示，还可使出风口12的上壁121与机壳10的外周面的连接处为与导风体20的上表面21形状匹配的外凸弧面，以便送风气流沿着外凸弧面更加顺畅地从出风口12上壁121过渡到机壳10的外周面。同理，可使出风口12的下壁122与机壳10外周面的连接处为与导风体20的下表面22形状匹配的外凸弧面。
进一步地，导风体20处于下吹位置时，可使其上表面21贴合于出风口12上壁121。由于出风口12上壁121的外凸弧面与导风体20上表面21的内凹弧面形状匹配，使得两者完美嵌合，能够增强密封性，避免送风气流从导风体20与出风口12上壁121之间泄漏而影响下吹效果。同理，导风体20处于上吹位置时，使其下表面22贴合于出风口12下壁122，使出风口12下壁122的外凸弧面与导风体20下表面22的内凹弧面形状匹配，使得两者完美嵌合，能够增强密封性，避免送风气流从导风体20与出风口12下壁122之间泄漏而影响上吹效果。
在一些实施例中，如图3和图4所示，可使导风体20朝向出风口12内侧的一端为尖端23，且可进一步使尖端23为弧形端面，以使送风气流更加顺畅地流至导风体20的上表面21或下表面22，减小阻力。
如图4和图5所示，出风口12为长度方向沿水平方向的矩形孔。如此一来，可使出风口12横向跨度更大，以利于送风气流更多地贴合于机壳10的外周面，使贴附效果更好。
如图1至图5所示，可使出风口12位于机壳10的前侧上部区域，机壳10的后侧下部开设有进风口11。立式空调室内机还包括离心风机50和板状换热器30。离心风机50设置在进风口11的前侧且轴线沿前后方向延伸，板状换热器30从上至下逐渐向前倾斜地设置在机壳10内的上部区域内。
如图5和图6所示，可使出风口12位于机壳10的前侧上部区域，机壳10的后侧下部开设有进风口11。立式空调室内机的还包括离心风机50和板状换热器30。离心风机50设置在进风口11的前侧且轴线沿前后方向延伸，板状换热器30从上至下逐渐向前倾斜地设置在机壳10内的上部区域内。机壳10内还可设置有风道40，使离心风机50设置在风道40内。风道40用于将离心风机50的气流向上输送，并吹向板状换热器30。
图6是立式空调室内机的齿轮齿条机构的示意图。
如图6所示，立式空调室内机包括至少一个齿轮齿条机构60，以用于驱动导风体20上下平移。每个齿轮齿条机构60包括电机61、相互啮合的齿轮62和齿条。电机61安装于机壳10。齿轮62连接于电机61。从齿条63沿竖直方向延伸且连接于导风体20。电机61带动齿轮62转动时，使齿条63上下平移，以驱动导风体20上下平移。具体地，齿轮齿条机构60的数量优选为两个，其中两个电机61分别安装于出风口12的横向两侧，以使导风体20更加平稳地上下平移。
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。
