可选地，所述风路切换件为沿横向延伸、横截面为三角形的长条状，其三个侧面依次为上表面、后表面和前表面。
可选地，所述风路切换件的转动轴线位于所述前表面和所述上表面的夹角处。
可选地，在所述风路切换件处于所述下导风位置时，所述上表面与所述后表面的交界棱边贴近所述蜗舌。
可选地，所述上表面为内凹弧形，以在所述风路切换件处于所述前导风位置时，将气流上扬引导。
可选地，壁挂式空调室内机还包括导风板，可绕横向轴线转动地设置在所述出风口的下侧，以在所述风路切换件处于所述前导风位置时，用于开闭所述风路切换件与所述出风口下端之间的出风口部分，或引导其出风方向。
可选地，所述后表面的下部相比上部向内凹陷，形成让位凹陷部，以在所述风路切换件处于所述下导风位置时，允许所述导风板嵌在所述让位凹陷部内，以使所述导风板的外表面与所述后表面上部表面平齐。
可选地，在所述风路切换件处于所述前导风位置时，所述前表面与所述上表面的交界棱边位于所述出风口上端的正下方，所述前表面与所述后表面的交界棱边位于所述出风口下端的正前方，所述前表面为外凸的曲线形。
可选地，壁挂式空调室内机还包括：可动面板，可上下平移地贴合于所述机壳的前侧表面，以遮蔽或敞开所述出风口上端与所述风路切换件之间的出风口部分。
可选地，所述壁挂式空调室内机还配置成：可使所述风路切换件处于所述前导风位置，使所述蜗壳下段转动至所述低位状态，以允许气流同时从出风口前侧和下侧流出。
本发明的壁挂式空调室内机通过可转动的风路切换件和蜗壳下段的共同配合来切换出风模式。当风路切换件处于前导风位置且蜗壳下段处于高位状态时，气流朝下的路径被封堵，只能依次沿蜗壳下段和风路切换件向前吹出出风口，朝前方或前上方送风，构成前吹模式。当风路切换件转动至下导风位置且蜗壳下段处于低位状态时，气流朝前的路径被封堵，只能从蜗壳下 段与风路切换件之间形成的空间向下流动，向下流出出风口，构成下吹模式。空调制冷时可选择前吹模式，使冷风送风距离更远，抵达远处后再逐渐下沉，形成淋浴式制冷效果。空调制热时可选择下吹模式，使热风更容易抵达地面，以实现地毯式送风效果，避免因热空气密度小导致无法抵达地面、使室内底层空间得不到制热。本发明的壁挂式空调室内机在制冷和制热时能选用不同的送风模式，使送风方向更匹配制冷、制热的特别需要，设计非常巧妙。
本领域现有技术常规方案大多利用一个转动的导流板来切换送风模式，但气流从风道内壁流向导流板的过程中，往往有很大的转向角度，使得气流损失很大。本发明则创造性地将蜗壳整体分割为两段，前吹模式下，蜗壳下段处于高位状态，其导风面朝上，使其与风路切换件的上表面完美地相切，使气流非常平稳、阻力更小地过渡到风路切换件上表面；下吹模式下，蜗壳下段向后翻转至低位状态，向后躲让以闪出足够空间，使气流能更顺畅地下吹。这种分割蜗壳的方案非常巧妙，从本质上提升了送风模式切换方案的送风效果。
进一步地，本发明的壁挂式空调室内机中，使得风路切换件为沿横向延伸、横截面为多边形的长条状，在前导风位置，由其上表面引导气流；在下导风位置时，由后表面引导气流。由于多边形的上表面和后表面夹持锐角，这就能够实现下述效果：当需要风路切换件朝前导风时，利用更加水平的上表面导风；当需要其朝下导风时，稍微转动一个较小角度，就能使后表面更加竖直，以便更好地向下导风。总之，本发明将风路切换件设置为多边形而非板状，在不同导风模式利用不同的侧面来引导气流，可达到更好的导风效果。

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、和/或引入新风等等。
图1是根据本发明一个实施例的壁挂式空调室内机在前吹模式下的示意图；图2是图1所示壁挂式空调室内机在下吹模式下的示意图。
如图1和图2所示，本发明实施例的壁挂式空调室内机一般性地可包括机壳10、风路切换件20、蜗舌200、蜗壳上段100和蜗壳下段70。
机壳10开设有朝前下方敞开的出风口12。机壳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。出风口12可开设于机壳10的前侧下部，使其跨越机壳10的前侧面下部和底面前部，使其朝前下方以便能够使其出风面积更大，且既能够用于朝前出风，又能用于朝下出风。出风口12用于将机壳10内的气流排向室内环境，以对室内空气进行调节。所排出的气流指的是被机壳10内的风机40作用，以加速流过出风口12的、用于调节室内环境的气流，例如制冷模式下的冷风、制热模式下的热风和/或新风模式下的新风气流等等。机壳10可为沿横向延伸的长条状，出风口12可为长度方向平行于机壳10的长度方向的长条状。
风路切换件20可绕横向轴线x(垂直于纸面的方向)转动地设置在出风口12的上端(A端)和下端(B端)之间。本文所称的横向指的是各图中垂直于纸面的方向，也就是机壳10的长度方向。可以理解的是，由于出风口12朝前下方敞开，所以出风口12的上端(A端)位于下端(B端)的前上方。机壳10的前壁的下端构成出风口12的上端，机壳10的底壁101的前端构成出风口12的下端。对于出风口12为长条状的方案，风路切换件20也为长条状。本实施例将风路切换件20设置在出风口12的上端和下端之间，是要将出风口12分隔为朝前敞开的部分和朝下敞开的部分，以便于分别朝前和朝下送风。
蜗舌200和蜗壳上段100前后间隔地设置在机壳10内，以限定出风道50。蜗舌200的前端与出风口12上端(A端)相接，蜗壳上段100的下端(C端)高于出风口12下端(B端)。具体地，可使蜗壳上段100的下端(C端)位于出风口12下端(B端)的后上方。
蜗壳下段70的上部可绕横向轴线z转动地安装于蜗壳上段100的下部。例如，可使蜗壳下段70的上端可绕横向轴线z转动地安装于蜗壳上段100的下端。
壁挂式空调室内机配置成：
可使风路切换件20转动至敞开出风口12前侧的前导风位置，使蜗壳下段70转动至一高位状态以使其前端与风路切换件20搭接，气流朝下的路径被封堵，使气流依次经蜗壳下段70上方和风路切换件20上方吹出出风口12， 如图1。壁挂式空调室内机的这种送风模式为前吹模式。蜗壳下段70的作用是将气流从蜗壳上段100上方成功过渡到风路切换件20上方。在前导风位置时，可使风路切换件20的上表面21从后向前逐渐向上倾斜，以使气流上扬吹出。进一步地，也可使蜗舌200的前部区段为从后向前逐渐向上倾斜的形态，以利于气流上扬吹出。
或者壁挂式空调室内机可配置成：
使风路切换件20转动至遮挡出风口12前侧的下导风位置，使蜗壳下段70转动至一低位状态以使其前端与出风口12下端(B端)相接，气流朝前的路径被封堵，以使气流经风路切换件20与蜗壳下段70之间向下吹出出风口12，如图2。此时，蜗壳下段70的作用是与风路切换件20共同限定出气流下吹的通道。壁挂式空调室内机的这种送风模式为下吹模式。
综上，本发明实施例通过可转动的风路切换件20和蜗壳下段70共同配合来切换出风模式。空调制冷时可选择前吹模式，使冷风送风距离更远，抵达远处后再逐渐下沉，形成淋浴式制冷效果。空调制热时可选择下吹模式，使热风更容易抵达地面，以实现地毯式送风效果，避免因热空气密度小导致无法抵达地面，使室内底层空间得不到制热。本发明的壁挂式空调室内机在制冷和制热时能选用不同的送风模式，使送风方向更匹配制冷、制热的特别需要，设计非常巧妙。
当然，应该理解的是，使空调制冷选择前吹模式、制热选择下吹模式只是本发明的一种推荐运行模式，空调制冷时当然也可选择下吹模式，制热时当然也可选择前吹模式，本发明对空调运行模式和送风模式的组合方式不作任何限定。
本领域现有技术常规方案大多利用一个可转动的导流板来实现前吹模式和下吹模式的切换。但是，当气流从风道内壁流向导流板的过程中，往往有很大的转向角度。具体地，气流在风道引导下朝前下方流动，遇到导流板后猛然转向前上方或者正下方，这使得气流损失很大。
发明人认识到这一问题，并且，为克服上述问题，本发明则创造性地将蜗壳整体分割为两段，前吹模式下，蜗壳下段70处于高位状态，其导风面朝上，使其与风路切换件20的上表面21完美地相切，使气流非常平稳、阻力更小地过渡到风路切换件20的上表面21。而在下吹模式下，蜗壳下段70向后翻转至低位状态，向后躲让以闪出足够空间，使气流能更顺畅地下吹。 这种分割蜗壳的方案非常巧妙，从本质上提升了送风模式切换方案的送风效果。
在本发明的一些实施例中，风路切换件20为沿横向延伸、横截面为多边形的长条状，其多个侧面包括相邻且夹持锐角的上表面21(EF)和后表面22(FG)。当风路切换件20处于前导风位置时，由上表面21用于引导气流(如图1)；处于下导风位置时，由后表面22引导气流(如图2)。由于多边形的风路切换件20的上表面21和后表面22夹持锐角，这就能够实现下述效果：当需要风路切换件20朝前导风时，利用更加水平的上表面21导风；当需要其朝下导风时，稍微转动一个较小角度，就能使后表面22更加竖直，以便更好地向下导风。总之，本发明实施例将风路切换件20设置为多边形而非板状，在不同导风模式利用不同的侧面导风，可达到更好的导风效果。
本发明实施例中所述的多边形指的是具有多个边的形状，并非严格数学意义的多边形。具体地，每个边可为直边，也可为曲边或各种形状的边。
进一步地，如图1和图2所示，优选使风路切换件20为沿横向延伸、横截面为三角形的长条状，其三个侧面依次为上表面21(EF)、后表面22(FG)和前表面23(EG)，其转动轴线x位于前表面23和上表面21的夹角处。如此，使上表面21和后表面22用于导风，使前表面23构成风路切换件20的外观，这样使得风路切换件20的结构最为简单。
此外，在风路切换件20处于前导风位置时，前表面23与上表面21的交界棱边(棱边E)位于出风口12上端的正下方，前表面23与后表面22的交界棱边(棱边G)位于出风口12下端的正前方，前表面23为外凸的曲线形，这样使得风路切换件20的前表面23形成一个圆角面，使得壁挂式空调室内机的外观更加美观。
如图1所示，可使上表面21为内凹弧形，以在风路切换件20处于前导风位置时，将气流上扬引导，实现上扬出风。如图2所示，当风路切换件20处于下导风位置时，上表面21与后表面22的交界棱边(棱边F)贴近蜗舌200，例如可以与蜗舌200直接接触，或者与蜗舌200之间具有极小的间隙，以避免风量大量向前泄漏。
图3是图2所示壁挂式空调室内机在导风板30进行导风时的示意图。
在一些实施例中，如图1至图3所示，壁挂式空调室内机还包括导风板 30。导风板30可绕横向轴线y转动地设置在出风口12的下侧，以在风路切换件20处于前导风位置时，用于开闭风路切换件20与出风口12下端之间的出风口部分，或引导其出风方向。图1示意了导风板30关闭风路切换件20与出风口12下端之间的出风口部分的状态，图2示意了导风板30打开风路切换件20与出风口12下端之间的出风口部分的状态，图3示意了导风板30在风路切换件20与出风口12下端之间的出风口部分进行导风的状态。
请参考图2，可使风路切换件20的后表面22的下部相比上部向内凹陷，形成让位凹陷部221(也可理解为台阶部)，以在风路切换件20处于下导风位置时，允许导风板30嵌在让位凹陷部221内，以使导风板30的外表面与后表面22上部表面平齐，使气流流动更加顺滑，减少气流阻力，参考图3。如此一来，导风板30的外表面与风路切换件20的后表面22共同构成下吹通道的前壁，蜗壳下段70构成下吹通道的后壁。
图4是图1所示壁挂式空调室内机运行最大送风模式的示意图。
在一些实施例中，如图4所示，壁挂式空调室内机还配置成：可使风路切换件20处于前导风位置，使蜗壳下段70转动至低位状态，以允许气流同时从出风口12前侧和下侧流出，可更加顺畅、大风量地流出。此时的送风模式称为最大送风模式。
图5是图1所示壁挂式空调室内机在将可动面板15平移至关闭位置时的示意图。
在一些实施例中，如图1和图5所示，壁挂式空调室内机还包括可动面板15。可动面板15可上下平移地贴合于机壳10的前侧表面，以遮蔽或敞开出风口12上端与风路切换件20之间的出风口部分。图1即示意了敞开状态，图5示意了可动面板15遮蔽出风口12的状态。当壁挂式空调室内机处于关机状态时，可利用可动面板15遮蔽出风口12的前侧，避免外界杂质进入机壳10的内部。更具体地，可使可动面板15的顶端不低于机壳10的顶端，以使可动面板15的外表面构成壁挂式空调室内机的前部外观，且使壁挂式空调室内机前部的视觉整体性更强。当然，当壁挂式空调室内机处于下吹模式时，也可利用可动面板15遮蔽出风口12的前侧。
本领域技术人员应该理解，本实施例中可运动的各部件包括可动面板15、风路切换件20、蜗壳下段70以及导风板30，每个运动部件都是在两个极限位置之间可转动和/或可平移，不同部件运动到不同位置，会形成多种组 合形态，形成多种送风模式。上文仅仅是以示例方式介绍了其中的前吹模式、下吹模式和最大送风模式，但实际的组合方式远不限于此，本发明并未将所有可能的送风模式示意出。
在一些实施例中，请参考图1，机壳10的顶部开设有进风口11，轴线沿横向延伸的贯流风机40设置于风道50的进口处。换热器60围绕在贯流风机40的上方。壁挂式空调室内机运行制冷模式或制热模式时，室内空气经进风口11进入机壳10的内部，与换热器60完成换热，最后被贯流风机40吸入风道50中，流向出风口12。
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。
