Description

壁挂式空调室内机及其导风板 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及其导风板。
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及其导风板。
本发明的目的是要扩大导风板左右方向的扩散角度。
本发明的进一步的目的是使导风板具有扬风功能，以实现送风气流上扬吹出。
一方面，本发明提供了一种用于壁挂式空调室内机的导风板，包括：
导风板本体，用于可绕平行于自身长度方向的转动轴线转动地安装于壁挂式空调室内机的出风口处；和
多个导流筋，凸出于导风板本体的打开出风口时朝上的第一侧面；且
多个导流筋沿导风板本体的长度方向间隔排列，并配置成在出风口流出的送风气流经过第一侧面时，引导部分送风气流逐渐朝导风板本体的长度方向的端部偏斜。
可选地，多个导流筋包括分别处于导风板本体不同长度段的多个第一导流筋和多个第二导流筋；第一导流筋和第二导流筋朝送风气流下游方向延伸并分别逐渐向导风板本体的长度方向的两端偏斜。
可选地，多个导流筋还包括第三导流筋，其位于多个第一导流筋和多个第二导流筋之间，且延伸方向垂直于导风板本体的长度方向。
可选地，多个第一导流筋和多个第二导流筋的数量相同，且关于第三导流筋所在平面对称分布。
可选地，导风板还包括：扬风板，与第一侧面间隔地安装于导风板本体，并配置成在第一侧面朝向出风口以对送风气流进行导向时，使扬风板引导送风气流向上偏斜。
可选地，扬风板为轴线平行于导风板本体的转动轴线，且凸面朝向第一侧面的弧形板。
可选地，扬风板短于并窄于导风板本体，且其在第一侧面的投影位于第一侧面在长度方向中部区段的靠近导风板本体出风端的半部区域。
可选地，扬风板与导风板本体之间形成的气流通道的临近出口的区段为渐缩形，利于气流加速流出。
可选地，导风板本体包括为平板的主体段和从主体段的靠近气流下游的端部朝第一侧面所面对方向弯折延伸出的弯折段。
另一方面，本发明还提供了一种壁挂式空调室内机，包括：壳体，其开设有出风口；和导风板，其为根据以上任一项的导风板，其中导风板本体可转动地安装于出风口处。
本发明的导风板中，导风板本体的第一侧面上设置有多个导流筋。当导风板处于导风状态，且出风口流出的送风气流流经第一侧面时，多个导流筋引导部分送风气流逐渐朝导风板本体的长度方向的端部偏斜，即偏离了导风板本体的宽度方向，使该部分送风气流逐渐向导风板本体长度方向两侧区域扩散。如此，增大了出风口在左右方向的扩散角度，实现了广角式送风，使房间内部温度更加均匀，人体感觉更加舒适。
进一步地，本发明的导风板使多个导流筋包括第一导流筋、第二导流筋以及第三导流筋，使中间的送风气流从第三导流筋两侧沿导风板本体的宽度方向流动，使两个侧送风气流在第一导流筋、第二导流筋的引导下分别朝两侧偏斜流动，这便形成一种扇形的广角送风效果，且气流分布更加均匀。
进一步地，本发明的导风板还设置了扬风板，在导风板本体的第一侧面朝向出风口以对送风气流进行导向时，使扬风板将引导所述送风气流向上偏斜，也就是使风上扬吹出。并且，由于设置了专门的扬风板，可将扬风角度设计地更大，这充分满足了空调制冷或者不吹人模式时对上扬角度的要求。本发明的导风板兼具扬风送风和广角式送风的功能，设计非常巧妙。
进一步地，本发明的导风板中，使扬风板与导风板本体间隔设置，以允许少部分送风气流从扬风板与导风板本体之间的气流通道流出，避免部分气流撞击杨风板的迎风端，产生不利的回流现象。并且，使气流通道的临近出口的区段为渐缩形，利于气流加速流出，避免气流在其中淤积。
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：
图1是根据本发明一个实施例的导风板的结构示意图；
图2是图1所示导风板的示意性俯视图；
图3是图2所示导风板的N-N剖视图；
图4是根据本发明一个实施例的壁挂式空调室内机的示意图。
具体实施方式
图1是根据本发明一个实施例的导风板的结构示意图；图2是图1所示导风板的示意性俯视图；图3是图2所示导风板的N-N剖视图，相比图1进行了放大处理；图4是根据本发明一个实施例的壁挂式空调室内机的示意图。图中用实心箭头示意了送风气流的流动方向，x轴为导风板本体的中心轴线，y轴平行于导风板本体的宽度方向。
如图1至图4所示，本发明实施例的导风板50包括导风板本体51以及多个导流筋541、542、543。导风板本体51用于可转动地安装在壁挂式空调室内机的壳体10的出风口12处。导风板本体51整体为长条状，其具有长度方向和宽度方向。导风板本体51的转动轴线x轴平行于导风板本体51的长度方向。导风板本体51用于打开或关闭出风口12，以及调节出风口12的出风角度。
例如图1至图4所示，可使导风板本体51以转动轴线水平或接近水平地安装于出风口12，使其长度方向平行于左右方向，以用于调节出风口12的上下出风角度。
从壳体10的内部经出风口12吹出的气流为送风气流。在空调制冷时， 送风气流为冷风；在空调制热时，送风气流为热风。导风板本体51在打开出风口12时，其朝上的一侧为第一侧，其表面为第一侧面511；朝下的一侧为第二侧，其表面为第二侧面512。定义导风板本体51在打开出风口12时靠近送风气流上游的一端为迎风端(B端)，靠近送风气流下游的一端为出风端(A端)。送风气流在导风板本体51的第一侧面511的流动方向是朝向出风端的。
多个导流筋541、542、543凸出于导风板本体51的第一侧面511，并配置成在送风气流流经第一侧面511时，引导至少部分送风气流逐渐朝导风板本体51的长度方向的端部偏斜。即，多个导流筋541、542、543引导部分送风气流逐渐朝左偏斜或者向右偏斜。或者，使一部分送风气流向左偏斜，一部分送风气流向右偏斜，如图2。可使多个导流筋与导风板本体51为由一体成型工艺制成的整体件，例如一体注塑成型。
现有技术的导风板在导风时，送风气流仅沿导风板的宽度方向流动，这使得气流接近平行地从出风口吹出，形成矩形气流。出风口的内部通常另设摆叶，以对出风口的左右出风方向进行调节。
而本发明实施例通过在导风板本体51上设置多个导流筋541、542、543，可使至少一部分送风气流偏离导风板本体51的宽度方向，使该部分送风气流逐渐向导风板本体51的长度方向两侧区域扩散，即向左或向右扩散，形成扇形气流。如此，应用该导风板的壁挂式空调室内机，增大了出风口在左右方向的扩散角度，实现了广角式送风效果，这使房间内部温度更加均匀，使人体感觉更加舒适。
在一些替代性方式中，可设置左右两组分别控制的摆叶。当左侧的多个摆叶朝左摆风，右侧的摆叶朝右摆风时，出风口也具有广角式送风效果。但是，由于摆叶相对于导风板处于出风口的更内侧，送风气流受到摆叶的偏斜引导之后，并非直接吹出出风口，而是还要撞击到导风板表面以受到导风板的上下引导作用。但是，偏斜的气流在撞击导风板表面，且受导风板向上或向下引导的过程中，其偏斜程度会产生不小的衰减，难以取得想要的广角式送风效果。
而本发明实施例中，直接由导风板本体51上的导流筋对送风气流施加偏斜作用力，送风气流产生偏斜后将直接从出风口12吹出，偏斜程度不受其他部件的影响。
在一些实施例中，可使前述的多个导流筋541、542、543包括分别处于导风板本体51的不同长度段的多个第一导流筋541和多个第二导流筋542。第一导流筋541和第二导流筋542朝送风气流下游方向(即从进风端到出风端的方向，y轴正向)延伸并分别逐渐向导风板本体51的长度方向的两端偏斜。请参考图2，使多个第一导流筋541沿送风气流下游方向延伸同时朝左偏斜，使多个第二导流筋542沿送风气流下游方向延伸同时朝右偏斜，以使左侧部分气流朝左偏斜，右侧部分气流朝右偏斜。如此可使壁挂式空调室内机形成一种扇形的广角送风效果，使送风角度更大，且气流分布更加均匀。
前述的多个导流筋还可包括第三导流筋543，第三导流筋543位于多个第一导流筋541和多个第二导流筋542之间，且延伸方向垂直于导风板本体51的长度方向。即，第三导流筋543的作用是将向不同方向偏斜的气流进行分隔。如图2所示，可使多个第一导流筋541和多个第二导流筋542的数量相同，且关于第三导流筋543所在平面C对称分布。这样可使其对送风气流分拆地更加均匀。此外，还可使第三导流筋543处于导风板本体51的长度方向两端的对称面上，以使其更加协调、美观，气流分配更加均匀。
如图2所示，可使第一导流筋541和第二导流筋542沿圆柱面弯曲，以在送风气流沿使第一导流筋541或第二导流筋542流动时，使送风气流的偏斜角度逐渐增大(偏斜角度指的是送风气流偏离导风板本体宽度方向的角度)，使送风气流的方向转变过程更加柔顺，这样可减少噪声。在一些替代性的实施例中，也可使导流筋在与导风板宽度方向呈锐角的平面内延伸。
在一些实施例中，如图1至图4所示，导风板50还包括扬风板52。扬风板52安装于导风板本体51，且与第一侧面511之间形成间隔。扬风板52配置成在第一侧面511朝向出风口12以对送风气流进行导向时，使扬风板52引导送风气流向上偏斜，也就是使风上扬吹出。例如，可使扬风板52为轴线平行于导风板本体51的转动轴线，且凸面朝向第一侧面511的弧形板。
空调机制冷时，将风上扬吹出利于实现室内更快速、均匀的制冷，且送风距离更远。此外，使冷风或热风上扬吹出还可使风躲避人体，以避免直吹人体带来不适。而本发明实施例中，由于设置了专门的扬风板，设计人员可将扬风角度设计地更大，以充分满足了空调对上扬角度的要求。本发明实施例的导风板兼具扬风和广角式送风的功能，设计非常巧妙，而且改进很小，成本较低。
如图1至图3所示，可使扬风板52短于并窄于导风板本体51，且其在第一侧面511的投影位于第一侧面511在长度方向中部区段的靠近导风板本体51出风端(A端)的半部区域。这样一来，使导风板50的长度方向的中部区域进行向上扬风，两侧区域不进行扬风但进行广角导风，这使得整个导风板的出风气流更加立体，分散，舒适度更高。
如图3所示，本发明实施例使扬风板52与导风板本体51间隔设置，以允许少部分送风气流从扬风板52与导风板本体51之间的气流通道521流出，避免气流撞击杨风板52的迎风端，产生不利的回流现象。并且，使扬风板52与导风板本体51之间形成的气流通道521的临近出口的区段为渐缩形，利于气流加速流出，避免气流在其中淤积。
扬风板52与导风板本体51通过多个连接筋55相连，以实现结构上的连接。可使扬风板52、连接筋55以及导风板本体51为由一体成型工艺制成的整体件，例如一体注塑成型。
在一些实施例中，可使导风板本体51包括为平板的主体段501和从主体段501的靠近气流下游的端部朝第一侧面511所面对方向弯折延伸(即朝导风板本体51的第一侧弯折延伸)出的弯折段502。在导风板导风过程中，弯折段502能够将气流上扬吹出。对于设置了扬风板52的实施例中，设置弯折段502能够形成前述的临近出口的区段为渐缩形的气流通道521。
本发明还提供了一种壁挂式空调室内机。如图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以及上述任一实施例的导风板50。壳体10上设置有进风口11和出风口12。导风板50的导风板本体51可转动地安装在出风口12处。
在一些实施例中，如图1至图4所示，导风板50还包括至少一个转臂53，其一端连接位于壳体10内部的驱动装置70，另一端连接导风板本体51。在驱动装置70的驱动下，转臂53带动导风板本体51绕转臂53的第一端转动。可设置多个转臂53，使多个转臂53沿导风板本体51的长度方向间隔排列。驱动装置70包括电机，用于直接或间接地带动转臂53转动。
如图4所示，壁挂式空调室内机可包括蒸发器20、风机30、风道40、摆叶60。蒸发器20用于与从进风口11进入壳体10的空气进行热交换，形成送风气流(具体地，制冷时为冷风，制热时为热风)。风道40的进口面向蒸发器20，出口连通出风口12。风机30可为贯流风机，其设置在风道40 的进口处，以促使空气从蒸发器20处流至出风口12处。摆叶60用于进行调节出风口12的左右出风方向。
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。
