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
现有的壁挂式空调室内机通常在机壳前侧下部设置一个长条状出风口，出风口朝向前下方，出风口处设置有导风板来引导上下送风方向。
在此基础上，一些现有技术对出风结构进行了很多改进，但由于受到出风口本身朝向的约束，空调的送风方向、送风范围和送风距离仍然受到极大限制，影响用户体验。
发明内容
本发明的一个目的是要克服上述问题或者至少部分地解决上述问题，提供一种能够聚合送风的壁挂式空调室内机。
本发明的进一步的目的是要提高气流聚合效果。
特别地，本发明提供了一种壁挂式空调室内机，其包括：
机壳，前侧开设有横向延伸的长条状的第一送风口，内部形成有连接所述第一送风口的风道，所述风道在邻近所述第一送风口处的上壁与下壁的间距沿气流方向逐渐变小，构成渐缩区段；和
导流件，为平行于所述第一送风口长度方向的杆状，设置在所述风道内且与其上壁和下壁分别限定有出风间隙，并用于将吹向所述第一送风口的气流导向所述风道的上壁和下壁，使气流在所述风道渐缩区段的引导下逐渐向气流中心聚合地流出所述第一送风口；且
所述第一送风口上、下边缘朝所述导流件的投影落在所述导流件之上。
可选地，所述导流件的横截面外形轮廓为具有上下两个尖端、前后两个外凸弯曲形的“橄榄形”；
所述风道上壁用于限定所述出风间隙的区段为凹侧朝下的弯曲段，其在所述导流件上方环绕所述导流件；且
所述风道下壁用于限定所述出风间隙的区段为从后向前逐渐向上倾斜延伸的内凹的弯曲段，其位于所述导流件前下方。
可选地，所述导流件的顶端与底端间距为H，所述第一送风口的宽度为 h，满足：4mm≤H-h≤10mm，
可选地，所述导流件外表面与所述风道上壁最近距离为d1，与所述风道下壁最近距离为d3，满足：1.5d1≤d3≤2d1。
可选地，所述导流件外表面与所述风道上壁最近距离为d1，所述第一送风口的宽度为h，满足：0.15h≤d1≤0.25h。
可选地，所述导流件的横截面外轮廓包括前弧线段、后弧线段，两者的顶端和底端以圆角过渡相接。
可选地，所述前弧线段的半径为R1，所述后弧线段的半径为R2，所述导流件的顶端与底端间距为H，满足：0.5≤R1/H≤0.8，0.5≤R2/H≤0.8。
可选地，所述前弧线段的半径大于所述后弧线段的半径。
可选地，所述机壳的底壁开设有朝下敞开且与所述风道相接的第二送风口，所述第二送风口处设置有导风板；
所述风道包括所述上壁、所述下壁和后壁，所述上壁前端和所述下壁前端限定出所述第一送风口，所述下壁后端和所述后壁下端限定出所述第二送风口，所述上壁和所述后壁限定出所述风道的进口；且
所述导风板处于关闭状态时，所述导流件的底端与所述导风板上表面间距为d2，所述导流件外表面与所述风道上壁最近距离为d1，满足：1.5d1≤d2≤2d1。
可选地，所述导流件配置成可前后移动，以便调节所述出风间隙的大小，且便于封闭所述第一送风口。
本发明的壁挂式空调室内机中，风道邻近第一送风口的区段为渐缩区段，使其过流截面沿气流方向逐渐变小。风道内的导流件与风道上壁和下壁分别限定出了出风间隙。气流吹向第一送风口的过程中，将在导流件引导下流向风道上壁和下壁，进入相应的出风间隙。由于出风间隙的过流截面更小，出风速度更高。高速气流在渐缩区段的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，满足了壁挂式空调室内机对远距离送风和强劲送风的需求。
此外，由于第一送风口上、下边缘朝导流件的投影落在导流件上，也就是使导流件竖直方向的尺寸相对更大，使导流件与风道上壁形成的出风间隙的向下倾斜部分更长，与风道下壁形成的出风间隙的向上倾斜的部分更长，以便更有力地引导气流分别向下和向上倾斜，以更大风力在导流件前方聚 合，使送风距离更远。
进一步地，本发明的壁挂式空调室内机使1.5d1≤d3≤2d1(d1为导流件外表面与风道上壁最近距离，d3为导流件外表面与风道下壁最近距离)，以使导流件与风道下壁的出风间隙更大，风量更大，与风道上壁的出风间隙更小，风量更小，如此使风道下壁上扬导风的力度大于风道上壁下倾导风的力度，使两股气流交汇聚集后将整体上扬流动。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验。并且，气流上扬吹出也有利于提升其送风距离。
进一步地，本发明的壁挂式空调室内对导流件外表面与风道上壁最近距离d1和第一送风口宽度h的关系进行特别设定，使0.15h≤d1≤0.25h，以使d1的宽度与第一送风口宽度h更加匹配，使气流聚合效果更好。

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的A处放大图。
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和导流件30。
机壳10的前侧开设有横向延伸的长条状的第一送风口11。机壳10为沿水平方向延伸的长条状，以用于挂在室内墙壁上。机壳10的横向也就是其长度方向，在图中用x表示。机壳10的内部形成有连接第一送风口11的风 道15。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15的蜗壳、蜗舌等机体部件，并非纯粹的空调外壳。第一送风口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。风道15在邻近第一送风口11处，其上壁151(具体为其ba段)和下壁152(具体为其ed段)的间距沿气流方向逐渐变小，构成风道15的渐缩区段，如图2。换言之，在邻近第一送风口11处，沿着气流方向，风道15的过流截面逐渐变小。
导流件30为平行于第一送风口11的长度方向(x方向)的杆状，其设置在风道15内且与其上壁151(的sa段)和下壁152(的ed段)分别限定有出风间隙154、155，并用于将吹向第一送风口11的气流导向风道15的上壁151和下壁152，使气流在风道15的渐缩区段(由上壁的ba段和下壁的ed段限定出)的引导下逐渐向气流中心聚合地流出第一送风口11。并且，第一送风口上边缘a、下边缘d朝导流件30的投影(分别为a0和d0)落在导流件30之上，而非落在导流件30之外，投影方向在图3中用虚线空心箭头示出。
由于增加了导流件30，出风间隙154、155的过流截面必然小于原有的风道15的过流截面，这使得气流速度更快。高速气流在风道15的渐缩区段的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力非常强劲，送风距离更远，满足了壁挂式空调室内机对远距离送风和强劲送风的需求，也使得送风范围更大，使室内空间各处制冷/制热速度更加均匀，使人体感觉更加舒适。并且，由于第一送风口11的上边缘a、下边缘d朝导流件30的投影a0和d0落在导流件30上。也就是使导流件30在竖直方向的尺寸相对更大，从而使导流件30与风道15的上壁151形成的出风间隙154的向下倾斜部分更长，与下壁152形成的出风间隙155的向上倾斜的部分更长，以便更有力地引导气流分别向下和向上倾斜，以更大风力在导流件30的前方聚合，使送风距离更远。
本发明实施例中，导流件30不仅与风道15的上壁151和下壁152限定出了出风间隙154、155，起到提升风速的作用，也恰好能将气流导向出风间隙154、155，或者说是强迫气流朝出风间隙154、155流动，以迫使气流接受风道15渐缩区段的聚合引导，形成最终的聚合送风效果。本发明实施例 仅通过改进风道15和增设一导流件30就实现了非常好的聚合送风效果，其结构非常简单，而且成本较低，易于实现量产推广，构思非常巧妙。
如图2所示，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。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15流动至第一送风口11处，最终从第一送风口11吹向室内。
图4是图1所示壁挂式空调室内机的导流件横截面示意图。
在一些实施例中，参考图2至图4，导流件30的横截面(沿前后方向延伸的剖切面剖切导流件30)的外形轮廓为具有上下两个尖端、前后两个外凸弯曲形的“橄榄形”。导流件30朝后的外凸弯曲形表面非常利于将气流拆分为两股并分别向上和向下引导，引导更加顺畅、气流阻力更小。导流件30的朝前凸出的外凸弯曲形表面能引导其附近的气流贴合于该表面流动，以逐渐向其中央方向聚合，以与风道15的渐缩状内壁共同对气流施加聚合作用，提升气流聚合效果。
风道15的上壁151用于限定出风间隙154的区段(即as段)为凹侧朝下的弯曲段，可为弧形或由多段弧形相接而成，具有前端点a，最高点b和后端点s。其在导流件30的上方环绕导流件30。风道15的下壁152用于限定出风间隙155的区段(即de段)为从后向前逐渐向上倾斜延伸的内凹的弯曲段，其位于导流件30的前下方。如此，使得出风间隙154和出风间隙155均为弯曲形状，或进一步为圆弧形，使气流方向改变地更加顺滑，减少气流阻力。
具体地，参考图4，可使导流件30的横截面外轮廓包括前弧线段31和后弧线段32。两者的顶端和底端以圆角r过渡相接。可使前弧线段31的半径大于后弧线段32的半径，以使后弧线段32相对更加凸出，从而使其与上壁151的间距更小，使前弧线段31相对更加平坦，以使其与上壁151的间距更大些，以利于气流更顺畅地流过出风间隙154。当然，在一些替代性实施例中，也可使前弧线段31的半径等于或小于后弧线段32的半径。在另一些替代性实施例中，可使前弧线段31和/或后弧线段32由多段圆弧相接而成， 具体不再赘述。
参考图3和图4，使前弧线段31的半径为R1，后弧线段32的半径为R2，导流件30的顶端与底端的间距为H，满足：0.5≤R1/H≤0.8，0.5≤R2/H≤0.8，进一步满足0.3≤R1/H≤0.6，0.3≤R2/H≤0.6。如此，使得导流件30的宽度(竖直方向的最大尺寸)与前后表面的弯曲度更加协调，以达到平衡导风效果和流动阻力的作用。
在一些实施例中，如图3所示，可使导流件30的顶端与底端的间距为H，第一送风口11的宽度为h，两者的关系满足：4mm≤H-h≤10mm，进一步满足6mm≤H-h≤8mm，以使导流件30与风道的上壁151形成的出风间隙154的向下倾斜部分以及与下壁152形成的出风间隙155的向上倾斜的部分不至于过长，从而避免气流阻力增大。
如图3所示，导流件30的外表面与上壁151的最近距离为d1，导流件30的外表面与下壁152最近距离为d3，优选使1.5d1≤d3≤2d1，进一步使1.7d1≤d3≤1.9d1，以使导流件30与风道的下壁152的间隙更大，风量更大，与风道上壁151的间隙更小，风量更小，如此使下壁152上扬导风的力度大于上壁151下倾导风的力度，使两股气流交汇聚集后将整体上扬流动，图2用箭头示意了气流走向，请参考。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验。并且，气流上扬吹出也有利于提升其送风距离。
此外，也可使下壁152的出风间隙155的气流上扬角度大于上壁151的出风间隙154的气流下倾角度，以便出风间隙155的气流带动出风间隙154的气流共同朝前上方上扬流动。
请参考图3，第一送风口11的宽度为h。发明人经多次测试发现，d1与h的关系对于送风距离存在较大影响。当满足0.15h≤d1≤0.25h时，进一步满足0.18h≤d1≤0.22h，送风距离较大。
在一些实施例中，如图2所示，机壳10的底壁开设有朝下敞开且与风道15相接的第二送风口12。如此一来，可由第二送风口12向壁挂式空调室内机的正下方送风。制热模式时向下送风更有利于加快房屋下层空间的温度升高速度，使人体更快感受到制热效果。
为与第一送风口11和第二送风口12相接，风道15包括前述的上壁151(ak)下壁152(de)和后壁153(fg)。其中，上壁151的前端(a)和下 壁152的前端(d)限定出第一送风口11。下壁152的后端(e)和后壁153的下端(f)限定出第二送风口12，上壁151(的k段)与后壁(的g端)共同限定出风道15的进口，贯流式的风机50位于风道15的进口处。后壁153为贯流风机的蜗壳，其整体上可为凹侧朝前的弯曲状结构。
请参考图2，第二送风口12处设置有导风板60。导风板60可转动地安装于机壳10，以用于打开或关闭第二送风口12和引导第二送风口12的送风方向。此外，第二送风口12处还可安装有摆叶组件等导风机构。后壁153为贯流风机的蜗壳，具体为凹侧朝前的弯曲状结构；上壁151除as段之外的区段(sck)为贯流风机的蜗舌。其包括向后下方延伸的kc段和向前下方延伸的cs段。并且，cs段的倾斜角度为θ，优选使θ≥25°，以利于将气流向斜下方引导，利于制热出风。
当导风板60处于关闭状态时，如图2，导流件30的底端与导风板60的上表面的间距为d2，气流经过该间隔流向出风间隙155。优选使1.5d1≤d2≤2d1，以使进入出风间隙155的气流更多，使下壁152上扬导风的力度大于上壁151下倾导风的力度，使两股气流交汇聚集后将整体上扬流动。
图5是图2所示壁挂式空调室内机在运行向下送风模式时的示意图；图6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。
在一些实施例中，如图5和图6所示，可使导流件30配置成可前后移动，以便调节出风间隙154、155的大小。具体地，可通过后移导流件30来调大出风间隙154、155，以提高风力，加快制冷/制热速度并延长送风距离；可通过前移导流件30来调小出风间隙154、155，以降低风力，模拟自然风，使气流舒适度更高。并且，导流件30的前后移动还便于封闭第一送风口11。由此，本发明实施例具有以下三种送风模式供用户选择，具体如下：
向前聚合送风模式：如图2所示，使导流件30位于第一送风口11的后方，使导风板60关闭第二送风口12，由第一送风口11聚合上扬送风，使气流避开人体，达到最高点后再向下散落，实现一种“淋浴式”的制冷体验。在空调运行制冷模式时，可以按照聚合送风模式送风。
向下送风模式：如图5所示，控制导流件30前移以关闭第一送风口11，使导风板60打开第二送风口12，在导风板60的引导下，由第二送风口12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。
最大送风模式：如图6所示，使导流件30位于第一送风口11的后方，使导风板60打开第二送风口12，由第一送风口11聚合上扬送风，在导风板60引导下，由第二送风口12向前下方送风。空调在运行制冷或制热模式时，均可选择最大送风模式。
需要注意的是，在前述实施例中，对于导流件30与风道15的上壁151、下壁152的尺寸关系等等限定，均是基于导流件30在打开第一送风口11的状态(如图2)。
图7是导流件的驱动机构的示意图。
在一些实施例中，如图7所示，用于驱动导流件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导流件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，以使导流件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。
