本发明的壁挂式空调室内机中，送风口外侧设置有分流件，出风气流吹向分流件，在分流件后表面引导下朝分流件的边缘发散地吹向室内环境，使出风气流更加分散，扩散范围更大，从而使室内制冷/制热速度更快，室内各处温度变化更加均匀，温差更小。出风气流分散吹出后不会强吹人体，也更加接近于自然风，使人感更加舒适。并且，由于送风口朝向前下方且同时设置分流件和导风板，可将送风口设计地更大，使出风更加顺畅，制冷制热速度更快。而且导风板和分流件之间没有任何分隔部件阻挡气流，进一步使出风气流的流动损失更少。并且，也可利用导风板将气流导向分流件，使分流件的分流出风效果更好。
进一步地，本发明的壁挂式空调室内机中，分流件朝向送风口的表面为外凸弯曲面。出风气流冲击到外凸弯曲面后再沿外凸弯曲面向边缘扩散，使得气流转向角度更小，气流转向地更加缓和、气流损失和噪音都更小。
进一步地，本发明的壁挂式空调室内机中，分流件配置成可沿接近或远离送风口的方向往复移动，以调节其与送风口的距离，从而能够调节送风口的风量，以匹配用户的风量需求。
进一步地，本发明的壁挂式空调室内机中，风道蜗舌与送风口相接的区段为从后向前逐渐向上倾斜的渐扩状出风段。如此，气流在流出送风口前已经开始向边缘扩散，更加利于出风气流的扩散吹出。

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是根据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剖视放大图；图3是图2所示壁挂式空调室内机在分流件30打开送风口11时的示意图。
如图1至图3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、分流件30和导风板60。
机壳10的前下部开设有朝向前下方的送风口11。具体地，机壳10为水平延伸的长条状，横截面大致为四边形。机壳10可包括顶壁、前壁、后壁和底壁和横向两个端壁，其后壁贴靠挂在室内墙壁上。送风口11位于机壳10的前下部，具体可使其贯穿机壳10的前壁底部以及底壁前部。机壳10的横向或者为长度方向在图中用x表示。
送风口11用于将机壳10内的气流吹向室内，调节室内空气。前述的气流可为壁挂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。
壁挂式空调室内机可为通过蒸气压缩制冷循环系统进行制冷/制热的空调器的室内机，其还包括换热器40和贯流风机50。换热器40设置在机壳10内，用于与流经其的气流进行换热，形成热交换气流，即冷风或热风，其可为三段式翅片换热器。贯流风机50设置于机壳10内，用于促使室内空气经机壳10顶部进风口13进入机壳10，使其与换热器40完成换热成为热交换气流，然后促使热交换气流经风道20流动至送风口11，最终从送风口11吹向室内。
分流件30设置在送风口11的前侧，以使送风口11的出风气流吹向分流件30，然后在分流件30表面引导下朝分流件30的边缘发散地吹向室内环境。例如图1至图3所示实施例中，送风口11的数量为一个，为长度方向平行于机壳10长度方向x的长条状，分流件30为平行于送风口11长度方向的杆状。此时，出风气流将在分流件30表面的引导下，朝分流件30的宽度方向(y方向)的两侧，也就是送风口11宽度方向的两侧吹出，也即在分 流件30表面引导下，送风气流的分为两路支流，分别向上和向下吹出。其中，向上吹出的气流上扬流动，流向更高更远的空间；向下吹出的气流下沉流动，流向更低更近的空间，使送风范围扩大。导风板60的转动轴线X平行于机壳10长度方向x，且位于导风板60的宽度方向的中央部位，以便使其转动范围更大，能够转动更大的角度而不被机壳干涉。
导风板60可转动地设置在送风口11的下侧。导风板60的作用在送风口11的下侧对出风气流的方向进行引导。当然，还可使导风板60可转动至在送风口11下侧遮蔽送风口11的位置。
本发明实施例中，如图3，出风气流从送风口11流出后，并非直接吹向室内环境，而是吹向分流件30和导风板60。吹向分流件30的气流在分流件30的后表面引导下朝分流件30的边缘发散地吹向室内环境，使出风气流更加分散，扩散范围更大，使得室内制冷/制热速度更快，室内各处温度变化更加均匀，温差更小。出风气流分散吹出后不会强吹人体，也更加接近于自然风，使人感更加舒适。
由于送风口11朝向前下方且同时设置分流件30和导风板60，可将送风口11设计地更大，出风更加顺畅，制冷制热速度更快。且既能向前送风，又能向下送风，充分满足制冷制热不同模式的送风需求。而且导风板60和分流件30之间没有任何分隔部件阻挡气流，进一步使出风气流的流动损失更少。
并且，本发明既可利用导风板60引导出风气流下出风方向，以利于制热下吹风，又能将导风板60转动至合适角度，使其将气流更好地导向分流件30，以利于分流件30更好地分流送风，参考图3，这种设计非常巧妙。
现有的壁挂式空调室内机更多将改进方向放在如何更好地增大送风距离或加强对出风气流的方向引导，以使其吹到设定区域，使其达到躲避人体的目标。而本实施例创造性地改变思路，在出风气流刚刚吹出送风口11就使其向多个方向(至少2个方向)扩散，避免其出现向前直吹的强力气流，从而既能够躲避人体，又能够使冷量/热量扩散范围更大，减少室内温差。并且，本实施例利用分流件30取代了常规的导风板，并通过分流，使气流流速降低，避免因流速过快、未能对导风板及机壳10表面充分降温、使其温度分布不均而出现凝露。此外，可对分流件30进行表面处理，增加表面的疏水功能，进一步防止其表面产生凝露。
当然，在一些替代性实施例中，也可使送风口为圆形、方形、圆角矩形等其它形状，使分流件为相应形状，使出风气流沿分流件的径向向外流动。还可使机壳开设有沿其长度方向排列的多个送风口，每个送风口设置独立的分流件和导风板，具体不再赘述。
在一些实施例中，参考图2和图3，可使分流件30可前后平移地安装于机壳10，以调节其与送风口11的距离，以便调节送风口11的风量。可以理解的是，分流件30越接近送风口11，送风口11的向前出风越受阻，其风量越小，但分流件30对出风气流的转向作用(促使气流朝其边缘方向转向)越强。当分流件30越远离送风口11，送风口11的出风越顺畅，风量越大，但对气流的转向作用变弱。
进一步地，可使分流件30和导风板60配置成可运动至共同关闭送风口11的位置，如图2，避免灰尘等异物经送风口11进入机壳10。
图4是图2所示壁挂式空调室内机在运行下吹模式时的示意图；图5是图2所示壁挂式空调室内机在运行最大送风模式时的示意图。
本发明实施例至少具有以下几种送风模式供用户选择，具体如下：
向前送风模式：如图3所示，使分流件30前移打开送风口11，使导风板60处于关闭状态或如图3所示的向前上方倾斜延伸的状态，由送风口11向前分流送风。在空调运行制冷模式时，可以按照该送风模式进行送风。
向下送风模式：如图4所示，控制分流件30后移以遮蔽送风口11，使导风板60转动至打开状态，以向下送风。在空调运行制热模式时，可以按照下送风模式送风，以利于加快制热速度。在该模式下，可使导风板60处于竖直延伸状态，其端部与风道20的蜗舌21邻近，以引导送风气流向下弯折流动。气流进入风道20后，截面逐渐增大实现扩压，经导风板60作用后转向竖直向下，再经过导风板60与风道20的蜗壳22限定的渐缩状通道，实现流出前的加速。最终制热送风风量大，风速高，风向竖直，有利于热风直达地面，地毯式送风效果良好。
最大送风模式：如图5所示，使分流件30和导风板60均打开，使送风口11同时朝前、朝下出风，以使风量最大。
在一些实施例中，如图2和图3所示，可使分流件30至少朝向送风口11的表面为外凸弯曲面32，以利于将气流朝分流件30的边缘引导。具体地，假如分流件30朝向送风口11的表面为平面，出风气流垂直地吹向该表面后， 将转向90°后，才能沿该表面向边缘扩散。而本实施例使该表面为外凸弯曲面，出风气流冲击到外凸弯曲面32后再沿外凸弯曲面32向边缘扩散，气流转向小于90°，在转向过程中，外凸弯曲面32的外凸形状使得方向转变地相对更加缓和、气流损失和噪音都更小。
例如在图2和图3所示实施例中，送风口11为长度方向平行于机壳10长度方向的长条状，分流件30为平行于送风口11长度方向的杆状。分流件30朝向送风口11和背向送风口11的两侧表面均为外凸弯曲面，分别为外凸弯曲面32和外凸弯曲面31，两者相接处构成两个顶端A1和A2，两个顶端A1和A2处可设置有圆角，使分流件30的横截面(垂直于x轴的截面)外形轮廓形成“橄榄形”。分流件30的这种结构较为简洁，易于制作，也使其外观更加美观。
具体地，如图2和图3所示，可使分流件30朝向送风口11的外凸弯曲面32由两段圆弧面CA1和CA2相接而成，以使外凸弯曲面32特别是其中间点C更加向外凸出，从而能够将吹向其的气流更均匀地向C点两侧分开。使背向送风口11的外凸弯曲面31为一段圆弧面，使其满足外观美观且便于制作即可。可进一步使外凸弯曲面32的两段圆弧面CA1、CA2的半径R1、R2和长度均相等，以使流向两者的气流趋于相等。当然，分流件30的横截面外形轮廓也可为椭圆形或其他不规则的形状，在此不再赘述。在一些替代性实施例中，若送风口和分流件均为圆形，可使外凸弯曲面为球冠状，在此不再赘述。
在一些实施例中，请参考图3，机壳10包括前后排列的蜗舌21和蜗壳22，两者共同限定出风道20，风道20的出口构成送风口11。本实施例所述的机壳10包括用于构成室内机基本框架的骨架和用于限定出风道20的蜗壳22、蜗舌21等机体部件，并非纯粹的空调外壳。风道20的进口处安装有长度方向平行于机壳10长度方向的贯流风机50。蜗舌21与送风口11相接的区段为从后向前逐渐向上倾斜的渐扩状的出风段sa。蜗舌21的这种形状使气流在流出送风口11前已经开始向边缘扩散，更加利于出风气流的扩散吹出。
更具体地，蜗舌21从其进口端至出口端依次包括进风段(kc)、中间段(cs)和出风段(sa)。其中，进风段(kc)从进口端(k)向后下方延伸。中间段(cs)从进风段(kc)的末端(c)向前下方延伸。出风段(sa)从中 间段(cs)的末端(s)向前上方延伸。蜗壳22位于蜗舌21后方，整体为凹侧朝前的弯曲形结构。可进一步使出风段(sa)为内凹的弧形，且各段均以圆角过渡，以使气流的方向转变更加平缓，减小流动损失。
如图2所示，可使风道20的出风段sa的表面轮廓与分流件30相应区段的表面轮廓相匹配，以使分流件30在关闭状态时贴合于风道2的出风端sa的表面，这使得分流件30能更好地封闭送风口11，并且，壁挂式空调室内机处于断电或者待机等非运行状态时，将分流件30移动至关闭状态，也使分流件30向内“嵌入”送风口11处，避免分流件30完全处于送风口11外影响美观。例如，当分流件30为橄榄形，其朝向送风口11的表面为外凸弯曲面32时，使出风段sa为内凹的弯曲面，以与之匹配。
图6是分流件的驱动机构的示意图。图2-图5为更好地示意风路走向，省略了驱动机构，图6为更好地示意驱动机构，省略了导风板60。
在一些实施例中，如图6所示，用于驱动分流件30前后平移的驱动机构为齿轮齿条机构，其安装于机壳10的横向侧部以不影响气流流动。驱动机构包括沿前后方向延伸且固定于分流件30的齿条71，与齿条71啮合的齿轮72，和用于驱动齿轮72转动以带动齿条71前后平移的电机73。电机73可固定于机壳10，齿条71可沿前后方向滑动地安装于机壳10。电机73能够受控地正反转，以使分流件30能沿前后方向往复平移。电机73可为步进电机。
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。
