Description
本发明涉及空气调节技术，特别是涉及一种壁挂式空调室内机。
现有技术中，为了调节空调室内机的送风方向，一般是在出风口处设置可以上下摆动的导风板。但是这种调节方式具有一定的缺陷。导风板仅能对靠近其内表面的气流进行导向，而无法对远离其内表面的气流进行导向，因此，这可能导致了从出风口排出的出风气流杂乱无章，气流梳理不顺畅，降低用户的体验感。
发明内容
本发明的一个目的旨在克服现有技术中的至少一个缺陷，提供一种壁挂式空调室内机。
本发明一个进一步的目的是要使得送风气流方向统一，气流梳理更加顺畅。
本发明另一个进一步的目的是要送风气流能够顺利地进入两个内导风板之间的间隙或者导风板本体和相邻的内导风板之间的间隙。
特别地，本发明提供了一种壁挂式空调室内机，其特征在于包括具有出风口的机壳和导风板，导风板包括：
导风板本体，可转动地设置于出风口处；
多层内导风板，设置于导风板本体的内侧，并且沿远离导风板本体内表面的方向依次间隔地固定于导风板本体，以便于与导风板本体共同引导送风气流。
进一步地，与导风板本体相邻的内导风板向导风板本体的正投影处于导风板本体的内部；且
在远离导风板本体内表面的方向上，其余各内导风板向上一层的正投影处于上一层的内导风板的内部。
进一步地，导风板本体和多层内导风板同侧端部处于同一平面上。
进一步地，导风板本体的宽度大于与其相邻的内导风板的宽度；且
多层内导风板的宽度沿远离导风板本体内表面的方向依次减小。
进一步地，导风板本体和各内导风板的内侧表面为同心圆弧面。
进一步地，导风板本体和与其相邻的内导风板的间距与导风板本体内表面的弧长之比处于1/5至1/3之间；且
在远离导风板本体内表面的方向上，每层内导风板距其相邻的下一层内导风板的间距与该内导风板弧长之比在1/5至1/3之间。
进一步地，壁挂式空调室内机还包括：
风道，设置于机壳内，用于将形成于机壳内的送风气流引导至出风口处；导风板配置成：
可转动至使导风板本体和各内导风板的内表面朝向风道，且导风板本体的第一端与风道的下壁相接的上吹位置，以利用导风板本体和各内导风板向上引导送风气流；
可转动至使导风板本体和各内导风板的内表面朝向风道，且导风板本体的第二端与风道的上壁相接的下吹位置，以利用导风板本体和多层内导风板向下引导送风气流。
进一步地，风道朝前下方延伸；且
当导风板处于上吹位置时，导风板本体和各内导风板临近风道的下壁的同侧端部所在平面与风道的下壁具有第一预设夹角；
当导风板处于下吹位置时，导风板本体和多层内导风板临近风道的上壁的同侧端部所在平面与风道的上壁具有第二预设夹角。
进一步地，壁挂式空调室内机还包括：
外导风板，可动地设置于出风口处，用于开闭出风口。
进一步地，外导风板的内侧表面为圆弧面；且外导风板配置成：
当导风板处于上吹位置时，外导风板可运动至导风板本体的外侧，以便与导风板本体和多层内导风板共同向上引导送风气流。
本发明的壁挂式空调室内机中，由于导风板本体可转动地设置于出风口处，多层内导风板设置于导风板本体的内侧，并且沿远离导风板本体内表面的方向依次间隔地固定于导风板本体，因此，当导风板本体转动某一位置时，送风气流不仅被导风板本体所导向，而且能够进入导风板本体和与其相邻的内导风板之间间隙以及相邻两个内导风板之间间隙，由导风板本体与多层内导风板共同导向，实现了多层次的导向作用，使得从出风口排出的送风气流方向统一，气流梳理更加顺畅，进而使的用户的舒适度更佳。
进一步地，本发明的壁挂式空调室内机中，导风板本体的宽度大于与其相邻的内导风板的宽度，并且多层内导风板的宽度沿远离导风板本体内表面的方向依次减小，以便于送风气流能够顺利地进入两个内导风板之间的间隙或者导风板本体和相邻的内导风板之间的间隙。

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：

请参见图1至图5，图1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2是根据本发明一个实施例的壁挂式空调室内机中导风板处于上吹位置时的截面图，其中箭头示出了送风气流的流动方向，图3是根据本发明一个实施例的壁挂式空调室内机中导风板处于最大送风位置时的截面图，其中箭头示出了送风气流的流动方向，图4是根据本发明一个实施例的壁挂式空调室内机中导风板处于下吹位置时的截面图，其中箭头示出了送风气流的流动方向，图5是根据本发明一个实施例的壁挂式空调室内机中外导风板处于关闭出风口时的截面图。
本发明提出一种壁挂式空调室内机1，该壁挂式空调室内机1一般性地可以包括机壳10、换热器20、换热风扇30等元器件。
机壳10作为壁挂式空调室内机1的外壳，保护着整个壁挂式空调室内机1，并且机壳10上还设置有至少一个进风口12和至少一个出风口13。在一些实施例中，出风口13可以开设于机壳10的下壁54，使其朝下敞开。
机壳10的内部还可以限定出换热空间16，换热空间16用于安装换热器20和换热风扇30，在换热风扇30的促使下室内空气可以从进风口12进入换热空间16，并与换热器20进行换热，形成送风气流，最终送风气流可以从出风口13排入室内，以调节室内的温度。
在一些实施例中，该壁挂式空调室内机1还可以包括导风板40，导风板40可以包括导风板本体42和多层内导风板44。
导风板本体42可转动地设置于出风口13处，多层内导风板44设置于导风板本体42的内侧，并且多层内导风板44沿远离导风板本体42内表面的方向依次间隔地固定于导风板本体42，以便于与导风板本体42共同引导送风气流。
具体地，该导风板40还可以包括两个侧板(图中未示出)，两个侧板可以分别设置于出风口13的横向两侧，导风板本体42和多层内导风板44均可以设置于两个侧板之间的位置，并与侧边固定连接。
两个侧板的外侧可以分别设置两个第一转动轴46，第一转动轴46分别与出风口13横向两侧处的机壳10转动连接，以实现使导风板本体42可转动地设置于出风口13处，并且多层内导风板44固定于导风板本体42上。
在本实施例中，由于导风板40可转动地设置于出风口13处，因此可以通过调节导风板40的转动角度，并利用导风板本体42和多层内导风板44的内表面改变送风气流的出风方向。
多层内导风板44与导风板本体42间隔设置，当导风板本体42转动某一位置时，送风气流不仅能被导风板本体42所导向，而且能够进入导风板本体42和与其相邻的内导风板44之间间隙以及相邻两个内导风板44之间间隙，使得送风气流还能被多层内导风板44所导向，实现了送风气流多层次的导向，使得从出风口13排出的送风气流方向统一，送风气流被梳理地更加顺畅，进而提高了用户的舒适度。
请参见图2至图5，在一些具体的实施例中，内导风板44的数量可以设置成两个，两个内导风板44依次间隔地设置于导风板本体42的内侧。在送风气流的流动方向上，位于最内侧的内导风板44可以利用其内表面导向至少一分部送分气流，其余送风气流可以依次进入两个内导风板44之间的间隙和位于靠后的内导风板44和导风板本体42之间的间隙，利用该内导风板44和导风板本体42的内表面对其余送风气流再次导向，使得向某一方向吹出的气流更加有层次感。
另外，发明人通过对本实施例中的壁挂式空调室内机1进行仿真分析后发现：同时利用导风板本体42和多层内导风板44导出(脱离导风板40后又汇聚在一起)的送风气流的方向和风速更加稳定，聚风效果更佳，在制冷时出风远端风速增加，送风距离更远，在制热时出风引导更顺畅，风量损失小，完全能够抵消由于增加多个内导风板44而增加的风阻损失，甚至优于单导板的出风效率，因此本实施例的壁挂式空调室内机1取得了意料不到的技术效果。
需要说明的是，上述举例仅是为了更清楚地描述本实施例的技术方案，并非对内导风板44的具体数量进行限定，本领域技术人员应当可以理解，本实施例中所述内导风板44的数量还可以为三个、四个或更多，不一而足。
如背景技术部分所述，现有技术中，为了调节空调室内机的送风方向，一般是在出风口处设置可以上下摆动的导风板。但是这种调节方式具有一定 的缺陷。导风板仅能对靠近其内表面的气流进行导向，而无法对远离其内表面的气流进行导向，因此，这可能导致了从出风口排出的出风气流杂乱无章，气流梳理不顺畅，降低用户的体验感。
为了克服上述现有技术的缺陷，本实施例的壁挂式空调室内机1在导风板本体42的内侧增加了多层间隔地且固定于导风板本体42的内导风板44，利用多层内导风板44和导风板本体42的内表面共同对送风气流导向，使得向某一方向吹出的气流更加有层次感，并且由于送风气流更多的导向，气流梳理更顺畅，整体的方向和风速更加稳定，使得送风气流的聚风效果更佳，出风效率更高，提高了用户的体验感。
请参见2至图5，在一些实施例中，与导风板本体42相邻的内导风板44向导风板本体42的正投影处于导风板本体42的内部，并且在远离导风板本体42内表面的方向上，其余各内导风板44向上一层的正投影处于上一层的内导风板44的内部。
在本实施例中，与导风板本体42相邻的内导风板44可以设置成与导风板本体42大小相等，也可以小于导风板本体42宽度，并且与导风板本体42相对，以使得导风板本体42可以包裹住该内导风板44。
同理，其余各内导风板44可以设置成与其上一层的内导风板44大小相等，也可以小于导风板本体42宽度，并与其上一层的内导风板44相对，使得上一层的内导风板44可以包裹住下一层的内导风板44。
通过上述限定后，在导风板40导风时，处于较外层的内导风板44或导风板本体42可以承接住从较内层的内导风板44漏过的送风气流，确保了送风气流能够受到多层导向，最终排出出风口13。
请参见图2至图5，在一些实施例中，导风板本体42和多层内导风板44同侧端部还可以配置成处于同一平面上。
导风板本体42和多层内导风板44的一端处于同一平面，导风板本体42和多层内导风板44的另外一端处于同一平面，以使得导风板40的外形更加美观。
请参见图2至图5，在一些实施例中，导风板本体42的宽度大于与其相邻的内导风板44的宽度，并且多层内导风板44的宽度沿远离导风板本体42内表面的方向依次减小。
也即，对于较内层的内导风板44，较外层的内导风板44的两端具有扩 展出较内层的内导风板44的错位区段，利用该错位区段不仅可以承接住从较内层的内导风板44漏过的送风气流，而且便于送风气流进入两个内导风板44之间的间隙，最终确保送风气流能够进入每两个相邻内导风板44之间的间隙。
同理，对于与导风板本体42相邻的内导风板44，导风板本体42的宽度大于与其相邻的内导风板44的宽度，导风板本体42的两端具有扩展出与其相邻的内导风板44的错位区段，利用该错位区段承接住从较内层的内导风板44漏过的送风气流。
请参见图2至图5，进一步地，导风板本体42和各内导风板44的内侧表面还可以配置成同心圆弧面。
在流体力学中，根据康达效应的原理，当流体(水流或气流)由偏离原本流动方向改为随着凸出的物体表面流动的倾向，当流体与它流过的物体表面之间存在表面摩擦时，只要曲率不大，流体就会顺着该物体表面流动。
因此，将导风板本体42和各内导风板44的内侧表面还可以配置成同心圆弧面可以使得流经导风板本体42和多层内导风板44内表面的送风气流更好地被吸附，使得导向作用更佳。
进一步地，导风板本体42和与其相邻的内导风板44的间距与导风板本体42内表面的弧长之比还可以配置成处于1/5至1/3之间，例如，1/5、1/4或者1/3等。
在远离导风板本体42内表面的方向上，每层内导风板44距其相邻的下一层内导风板44的间距与该内导风板44弧长之比在1/5至1/3之间例如1/5、1/4或者1/3等。
优选地，导风板本体42和与其相邻的内导风板44的间距导风板本体42内表面的弧长之比还可以与每层内导风板44距其相邻的下一层内导风板44的间距与该内导风板44弧长之比配置成相同。
对于导风板本体42和内导风板44，弧长越长，其导风能力越强，因此通过上述限定使得弧长越长的导风板本体42或内导风板44气内表面对应的间距越大，送风气流流量越大，更加合理地将送风气流分配给导风板本体42和各内导风板44，以对送风气流更多地引导，使送风气流梳理更顺畅。
当然，在本领域技术人员知晓本实施例的技术方案后还可以将导风板本体42和多层内导风板44的内表面设置成平面。与上述实施例相比，平板状 的导风板本体42和多层内导风板44基本上可以实现更多地引导送风气流，但是圆弧状的内表面取得的技术效果更佳。
请参见图2至图5，在一些实施例中，该壁挂式空调室内机1还可以包括风道50，风道50设置于机壳10内，用于将形成于机壳10内的送风气流引导至出风口13处。
请参见图2，导风板40还可以转动至使导风板本体42和各内导风板44的内表面朝向风道50，且导风板本体42的第一端与风道50的下壁54相接的上吹位置，以封堵送风气流向下排出的通路，进而利用导风板本体42和各内导风板44向上引导送风气流。在使用过程中，用户可以在制冷模式下将导风板40调至上吹位置，以使冷风向上排出，避免冷风下吹直吹人体。
请参见图4，导风板40还可以转动至使导风板本体42和各内导风板44的内表面朝向风道50，且导风板本体42的第二端与风道50上壁52相接的下吹位置，以封堵送风气流向上排出的通路，进而利用导风板本体42和多层内导风板44向下引导送风气流。在使用过程中，用户可以在制热模式下将导风板40调至下吹位置，以使热风能够向下排出，以克服由于热风密度相对较小而无法达到地面的缺陷。
需要说明的是，上述举例仅是为了更加清楚地描述本实施例的导风板40的工作原理，并非用于限定导风板40处于何种位置时壁挂式空调室内机1必然要处于何种调温模式(制热或者制冷)。用户可以根据实际情况任意调节导风板40的工作位置，例如，在制热模式下将导风板40调节至上吹位置，在制冷模式下将导风板40调节至下吹位置等，在此不作赘述。
进一步地，风道50还可以朝前下方延伸。当导风板40处于上吹位置时，导风板本体42和各内导风板44临近风道50的下壁54的同侧端部所在平面与风道50下壁54具有第一预设夹角。
当导风板40处于下吹位置时，导风板本体42和多层内导风板44临近风道50上壁52的同侧端部所在平面与风道50上壁52具有第二预设夹角，以便送风气流进入导风板本体42与内导风板44以及相邻的内导风板44之间的间隙
请参见图2，图2中S1表示导风板本体42和各内导风板44临近风道50的下壁54的同侧端部所在平面，α表示第一预设夹角。
在一些实施例中，由于导风板本体42的宽度最大，多层内导风板44沿 远离导风板本体42内表面的方向依次减小，因此当风道50处于朝前下方延伸，且导风板40处于上吹位置时，平面S1与风道50的下壁54形成第一预设夹角α，以使得各内导风板44与风道50的下壁54不接触，并且在远离导风板本体42内表面的方向上，各内导风板44逐渐远离风道50的下壁54，便于送风气流能够顺畅地进入导风板本体42与内导风板44以及各导风板40之间的间隙。
请参见图4，图中S2表示导风板本体42和各内导风板44临近风道50的上壁52的同侧端部所在平面，β表示第二预设夹角。同理，当风道50处于朝前下方延伸，且导风板40处于下吹位置时，平面S2与风道50上壁52形成第二预设夹角β，以使得各内导风板44与风道50的上壁52不接触，并且在远离导风板本体42内表面的方向上，各内导风板44逐渐远离风道50的上壁52，便于送风气流能够顺畅地进入导风板本体42与内导风板44以及各导风板40之间的间隙。
请参见图3，导风板40还可以转动至风道50的内部，且使导风板本体42和各内导风板44大致与风道50平行的最大出风位置，此时导风板40几乎不改变送风气流的方向，并且使送风气流的出风量处于最大。
请参见图5，图5是根据本发明一个实施例的壁挂式空调室内机中外导风板处于关闭出风口时的截面图。
在一些实施例中，该壁挂式空调室内机1还可以包括外导风板60，外导风板60可动地设置于出风口13处，用于开闭出风口13。
具体地，外导风板60可以通过第二转动轴62转动地连接在机壳10的下壁54上，当导风板40转动至风道50的内部后，外导风板60可以转动至关闭出风口13的位置。
请参见图2，进一步地，外导风板60的内侧表面还可以配置成为圆弧面，当导风板40处于上吹位置时，外导风板60可运动至导风板本体42的外侧，以便与导风板本体42和多层内导风板44共同向上引导送风气流。
也即，外导风板60不仅能够起到密封出风口13的作用，而且当导风板40处于上吹位置时，外导风板60可以运动至导风板本体42的外侧，与导风板本体42和多层内导风板44一起参与导风。
进一步地，外导风板60的宽度可以配置成大于导风板本体42，并且当导风板40处于上吹位置时，外导风板60的弧长是外导风板60与导风板本 体42间距的1/5至1/3之间，这样不仅使外导风板60能够承接并导向从导风板本体42漏出的送风气流，而且使送风气流被外导风板60更多地吸附，导向作用更佳。
本发明的壁挂式空调室内机1中，由于导风板本体42可转动地设置于出风口13处，多层内导风板44设置于导风板本体42的内侧，并且沿远离导风板本体42内表面的方向依次间隔地固定于导风板本体42，因此，当导风板本体42转动某一位置时，送风气流不仅被导风板本体42所导向，而且能够进入导风板本体42和与其相邻的内导风板44之间间隙以及相邻两个内导风板44之间间隙，由导风板本体42与多层内导风板44共同导向，实现了多层次的导向作用，使得从出风口13排出的送风气流方向统一，气流梳理更加顺畅，进而使的用户的舒适度更佳。
进一步地，本发明的壁挂式空调室内机1中，导风板本体42的宽度大于与其相邻的内导风板44的宽度，并且多层内导风板44的宽度沿远离导风板本体42内表面的方向依次减小，以便于送风气流能够顺利地进入两个内导风板44之间的间隙或者导风板本体42和相邻的内导风板44之间的间隙。
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。
