Description

壁挂式空调室内机 技术领域
本发明涉及空气调节技术领域，特别涉及一种壁挂式空调室内机。
背景技术
随着时代的发展和技术的进步，用户不仅期望空调具有更快的制冷和制热速度，还越来越关注空调的舒适性能。
然而，为了实现更加快速地制冷和制热，难免需要进行大风量送风。但是，当风速过大的冷风或热风直吹人体时，必然会引起人体的不适。人体长期被冷风直吹还会引发空调病。
因此，如何实现空调的舒适送风成为空调行业亟待解决的技术难题。
发明内容
本发明的目的是要提供一种克服上述问题或者至少部分地解决上述问题的壁挂式空调室内机。
本发明的目的是要提高壁挂式空调室内机上扬出风效果。
本发明的进一步的目的是要丰富出风量和出风方向的调节模式。
特别地，本发明提供了一种壁挂式空调室内机，其包括：
壳体，其限定有朝前下方敞开的出风口；和
至少一个导风板，每个所述导风板可转动地设置在所述出风口处，以处于关闭状态以遮挡所述出风口或处于打开状态以引导所述出风口的出风方向，每个所述导风板在处于所述关闭状态时朝向所述壳体内侧的表面为导风面，在使所述导风面朝上的状态时朝前的一端为出风端；且
每个所述导风板开设有多个透风孔，在所述导风板处于所述关闭状态时，至少部分所述透风孔的轴线方向朝前上方倾斜，所述导风面上具有多个凸起部，每个所述凸起部位于一个所述透风孔进口处的更接近所述出风端的边缘处。
可选地，每个所述导风板为长度方向平行于所述壳体的长度方向的长条状，至少部分所述透风孔为长度方向平行于所述导风板的长度方向的长条孔；且
每个所述凸起部为沿所述透风孔长度方向延伸的长条状。
可选地，所述凸起部的横截面外轮廓为圆弧状。
可选地，所述凸起部的横截面外轮廓半径在0.5mm至1mm之间。
可选地，所述凸起部的横截面外轮廓的圆弧圆心角大于或等于180°。
可选地，长条状的所述透风孔的长度在25mm至30mm之间，宽度在2mm至3mm之间。
可选地，每个所述导风板背离所述导风面的另一表面为非导风面；每个所述透风孔出口处更接近所述出风端的内壁与所述导风板的非导风面之间采用圆角过渡。
可选地，所述多个透风孔设置在所述导风板的邻近所述出风端的半部。
可选地，在所述导风板处于所述关闭状态时，至少部分所述透风孔的轴线方向朝上倾斜，且仰角在28°至32°之间。
可选地，所述导风板的数量为两个，其沿所述出风口的宽度方向排列；且在两个所述导风板均处于所述关闭状态时，位于下侧的所述导风板与所述出风口的下边缘之间具有用于出风的间隙。
本发明的壁挂式空调室内机中，导风板上开设有多个透风孔。当导风板处于关闭状态时，至少部分透风孔的轴线方向朝前上方倾斜，使关闭状态的导风板也能上扬导风。如此，当需要进行舒适送风时，可使导风板处于关闭状态，使换热气流从多个透风孔向外上扬吹出，使得气流冲击力更小，使室内风感更舒适，且气流上扬流动，能够躲避人体。由于出风口朝前下方，当导风板处于关闭状态时，其导风面从后向前逐渐向上倾斜。基于此，本发明特别使透风孔接近出风端的边缘处设置凸起部，部分气流冲击到凸起部后，产生康达效应(当流体与它流过的物体表面之间存在表面摩擦，也可以说产生流体粘性时，只要曲率不大，流体就会顺着该物体表面流动)，沿凸起部的表面进一步向上流动，使得气流更多地从上侧的透风孔吹出，使得气流的避人效果更好。
进一步地，本发明的壁挂式空调室内机中，透风孔出口处更接近出风端的内壁与导风板非导风面之间采用圆角过渡，在气流流出透风孔后，在该圆角表面产生康达效应，能进一步引导气流向上倾斜流动，提高上扬送风效果。
进一步地，本发明的壁挂式空调室内机中，多个透风孔设置在导风板的邻近出风端的半部，在导风板导风时，部分气流先被非开孔区域(导风板靠近进风端的半部)引导，流动方向基本定型，再经过开孔区域，方向不会有 太大改变。如此，使导风板不会因开设太多透风孔使其方向引导功能过于受损。
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。

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示意性前视图；图2是图1所示壁挂式空调室内机的C-C剖视放大图；图3是图2所示壁挂式空调室内机中的导风板50放大示意图。图中用箭头示意了气流的流动方向；图4是图2所示壁挂式空调室内机在两导风板50转动至前导风位置时的示意图。
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和至少一个导风板50。壳体10开设有朝前下方敞开的出风口12。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。出风口12可开设于壳体10的前侧下部，以便朝前下方敞开。出风口12用于将壳体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壳体10内的风机作用，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、制热模式下的热风以及新风模式下的新风气流等等。壳体10可为长度方向水平设置的长条状，如图1。出风口12可为长度方向平行于壳体10的长度方向的长条状。
本发明实施例的每个导风板50可转动地设置在出风口12处，以处于关 闭状态以遮挡出风口12(如图2)或处于打开状态以引导出风口12的出风方向(如图4)。导风板50的数量可为一个，也可为多个。设置多个导风板50时，各导风板50各自配置自己的电机，运行独立受控。例如图2所示，可设置两个导风板50，且使两个导风板50沿出风口12的宽度方向排列，使两者的转动轴X1、X2均平行于导风板50的长度方向。
每个导风板50在处于关闭状态时朝向壳体10内侧的表面为导风面501，背离导风面501的另一表面(也就是导风板50在处于关闭状态时朝向壳体10外部的表面)为非导风面502导风面501，在使导风面501朝上的状态时朝前的一端为出风端(A端)，朝后的一端为进风端(B端)(如图4)。在导风面501朝上的导风状态下，气流主体从进风端B朝出风端A的方向流动。每个导风板50开设有多个透风孔51，在导风板50处于关闭状态时，至少部分透风孔51的轴线方向朝前上方倾斜。至少部分指的是一部分或者全部。优选如图3所示，使全部的透风孔51的轴线方向朝前上方倾斜。优选地，在导风板50处于关闭状态时，轴线方向朝前上方倾斜的透风孔51的轴线方向的仰角a在28°至32°之间，优选在29°至31°之间，此范围内可以同时兼顾防直吹效果和送风距离。导风面501上具有多个凸起部53，每个凸起部53位于一个透风孔51进口处的更接近出风端A的边缘处(即上边缘)，如图3。
本发明实施例的壁挂式空调室内机中，当需要进行舒适送风时，可使导风板50处于关闭状态，使换热气流从多个透风孔51向外上扬吹出，使得气流冲击力更小，使室内风感更舒适，且气流上扬流动，能够躲避人体。由于出风口12朝前下方，当导风板50处于关闭状态时，其导风面501从后向前逐渐向上倾斜，如图2。基于此，本发明实施例特别使透风孔51接近出风端A的边缘处设置凸起部53，部分气流冲击到凸起部53后，产生康达效应(当流体与它流过的物体表面之间存在表面摩擦，也可以说产生流体粘性时，只要曲率不大，流体就会顺着该物体表面流动)，沿凸起部53的表面进一步向上流动，使得气流更多地从上侧的透风孔51吹出，使得气流的避人效果更好。
在一些实施例中，如图1至图4所示，可使每个导风板50长度方向平行于壳体10的长度方向的长条状，至少部分透风孔51为长度方向平行于导风板50的长度方向的长条孔。长条孔指的是透风孔51的整体形状为长条状， 并非局限为矩形或圆角矩形。每个所述凸起部53为沿透风孔51的长度方向延伸的长条状。本发明实施例导风板50并非常规的微孔导风板，其透风孔51的作用并非简单的实现微风效果，而是将气流上扬引导。故本实施例将透风孔51设计为长条状，使其具有两个很长的上扬的孔壁，能够更好地实现上扬导风。
进一步地，如图3所示，优选使凸起部53的横截面外轮廓为圆弧状，一方面使外形更加圆润，更有利于形成康达效应，另一方面也便于加工制作。可进一步使凸起部53横截面外轮廓半径R1在0.5mm至1mm之间，优选设置在0.6mm至0.9mm之间。还可使凸起部53横截面外轮廓的圆弧圆心角大于或等于180°。这种形状的凸起部53外轮廓使得康达效应更好，且使气流流动损失更小。
在一些实施例中，参考图1和图3，可使长条状的透风孔51的长度L在25mm至30mm之间，更优选设置在26mm至29mm之间。透风孔51的宽度d在2mm至3mm之间，更优选设置在2.2mm至2.8mm之间。如此，既满足了透风孔51的透风风量的要求，又满足导风板50的刚度需求，还避免因透风孔51太大而过度影响导风板50的导风功能。
在一些实施例中，如图1至图4所示，可使每个透风孔51出口处更接近出风端A的内壁与导风板50的非导风面502导风面501之间采用圆角(R2)过渡，在气流流出透风孔51后，在该圆角表面产生康达效应，能进一步引导气流向上倾斜流动，提高上扬送风效果。
在一些实施例中，前述的多个透风孔51设置在导风板50的邻近出风端A的半部。如此，在导风板50导风时，部分气流先被非开孔区域(导风板50靠近进风端B的半部)引导，流动方向基本定型，再经过开孔区域，方向不会有太大改变。如此，使导风板50不会因开设太多透风孔51使其方向引导功能过于受损。
在一些实施例中，如图2所示，对于导风板50为两个的实施例而言，在两个导风板50均处于关闭状态时，位于下侧的导风板50与出风口12的下边缘(N)之间具有用于出风的间隙(BN)，如此，当导风板50处于图2所示的关闭状态时，气流分为上下两股，上面的气流在导风板50的透风孔51引导下，上扬吹出。下面一股经导风板50与出风口12下边缘之间的间隙向下吹出。如此既能实现防直吹送风效果，还可以形成上下双向风，形成环 绕形气流，有利于室内空气换热，提升舒适性
如图2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20的引导下吹向出风口12。风机40优选为轴线平行于壳体10的长度方向的贯流风机，其设置在风道20的进口处。换热器30可为三段式换热器。
图5是图2所示壁挂式空调室内机在两导风板50转动至下导风位置时的示意图；图6是图2所示壁挂式空调室内机在两导风板50转动至最大导风位置时的示意图。本发明实施例中具有多种送风模式；图7是本发明实施例的壁挂式空调室内机运行防直吹模式的流体仿真示意图。
如图2所示，壁挂式空调室内机可运行防直吹模式。使各导风板50均处于关闭状态，使送风气流经导风板50的透风孔51以及下侧导风板50与出风口12下边缘之间的间隙向外吹出，其结果参考图7的仿真效果图。
如图4所示，壁挂式空调室内机可运行前吹模式。将两导风板50转动至使导风面501朝上、出风端A朝前的前导风位置，以将送风气流朝前方或前上方引导。空调制冷运行时，可选择采用前吹模式送风，以使送风气流扩散地更快，送风高度更高，形成淋浴式制冷体验。
如图5所示，壁挂式空调室内还可运行下沉送风模式。使各导风板50转动至使导风面501朝前，出风端A朝下的下导风位置，以更好地向下导风。空调制热运行时，可运行下沉送风模式，使热空气下沉到地面后再向上流动，形成地毯式制热效果，避免室内空间底部制热效果不良。
如图6所示，壁挂式空调室内还可运行最大送风模式。导风板50转动至从后向前逐渐向下倾斜的状态，使其宽度方向恰好顺沿着气流方向，使其对气流的阻力最小，使出风最为顺畅，风量最大。
当然，上述各送风模式仅仅是一些示例，并非限定壁挂式空调室内机仅仅具有这几种送风模式。空调根据室内工况，可自行调节或者受用于控制地，将导风板50转动至其他角度，实现其他送风效果。
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。
