与现有技术相比， 本发明的优点和积极效果是： 在空调中应用本发明的空 调送风装置之后， 将空调内部风道中的热交换风经贯通风道前端吹出的同时， 能利用负压作用吸入部分外部未热交换的非热交换风参与到空调最后的出风 中， 增大了空调的整体进风量， 加快了室内空气的流动， 进一歩提高了室内空 气的整体均匀性。 且， 这样的混合空气较为柔和， 吹到用户身上会感觉更加舒 适， 提高了用户舒适性体验效果。 此外， 通过采用多个单体部件形式的环形导 风体组合构成空调送风装置， 不仅便于根据送风要求灵活控制每个环形导风体 的结构， 方便地加工出结构不同的各环形导风体， 还可以灵活选择整个空调送 风装置在空调中的装配方式， 进而提高了空调送风装置的适用范围和空调的生 产效率。 而且， 环形导风体采用径向截面为曲线面的结构， 在引导热交换风顺 利流动的同时， 提高作为初级气流的流动速度， 便于获取作为次级气流的非热 交换风进入贯流风道中， 在实现出风风量增大的同时， 获得温度适宜的出风。
结合附图阅读本发明的具体实施方式后， 本发明的其他特点和优点将变得 更加清楚。

具体实施方式：
下面结合附图和具体实施方式对本发明的技术方案作进一歩详细的说明。 首先， 对该具体实施方式中涉及到的技术术语作一简要说明： 下述在提到 每个结构件的前端或后端时， 是以结构件正常使用状态下相对于使用者的位置 来定义的； 对于多个结构件的排列位置进行前或后的描述时， 也是以多个结构 件构成的装置在正常使用状态下相对于使用者的位置所做的定义。 下述的热交 换风是指来自空调内部、 经热交换器热交换后的风； 非热交换风是指来自空调 所处环境空间的风， 是相对于热交换风而言、 不是直接来自于热交换器的部分 风； 混合风是指热交换风与非热交换风混合形成的风。 下述的环， 是指环绕形 成的封闭结构， 并不局限于圆环。
其次， 简要说明本发明的设计思路： 对于能够将空调热交换器热交换风及 外部非热交换风形成混合风而送出的空调送风装置来说， 形成热交换风风道的 环形导风体的结构、 尤其是其径向截面的结构对气流的运动至关重要， 进而会 影响到空调送风装置所吸入的外部非热交换风的风量及混合风出风的温度。 所 以， 本发明从环形导风体的结构、 尤其是其径向截面形状作为研究点， 来寻求 能提高空调送风装置性能的较佳结构。
请参考图 1， 该图所示为具有空调送风装置 1的空调一个实施例的结构示 意图。
如图 1所示意， 该实施例的空调包括有构成空调壳体的前面板 2、 后背板 3、 左侧面板、 右侧面板及顶板和底板 （图中未标注）， 壳体限定了空调的内部 风道 4。 在空调前面板 2的上部开设有混合风出口 21， 在空调后背板 3上部、 与前面板 2上的混合风出口 21相对应的位置处开设有非热交换风进口 31。 在 内部风道 4中自下而上设置有风机 6、 热交换器 5和空调送风装置 1， 且风机 6 的设置使得空调内部风道 4中的风从前面板 2上的混合风出口 21吹出。
其中， 空调送风装置 1的结构请参考图 2的立体结构示意图及图 3的径向 截面结构示意图。
如图 2及图 3所示意， 同时结合图 1所示意， 该实施例的空调送风装置 1 包括有三个环形导风体， 分别为前端环形导风体 11、 第一中间环形导风体 13 和后端环形导风体 12。前后依次排列的这三个环形导风体中的每一个环形导风 体均为单体部件， 独立成型。 其中， 前端环形导风体 11中间贯通、 具有前后两 个开口， 前开口为出风口、 且为混合风出口 111， 后开口为进风口 112; 第一中 间环形导风体 13中间贯通、 具有前后两个开口， 分别为出风口 131和进风口 132； 后端环形导风体 12中间贯通、 具有前后两个开口， 前开口为出风口 121， 后开口为进风口、 且为非热交换风进口 122。 前端环形导风体 11、 第一中间环 形导风体 13和后端环形导风体 12前后依次排列之后， 中间形成前后贯通所有 三个环形导风体的贯通风道 （图中未标注）。 而且， 前端环形导风体 11与第一 中间环形导风体 13之间形成有第一环形热交换风风道 14， 第一中间环形导风 体 13与后端环形导风体 12之间形成有第二环形热交换风风道 15，空调中的内 部风道 4将通过第一环形热交换风风道 14及第二环形热交换风风道 15与空调 送风装置 1中的贯通风道相连通。 其中， 空调送风装置 1中的各环形导风体的 径向截面均为曲线面， 以便在引导热交换风顺利流动的同时， 提高作为初级气 流的流动速度， 便于获取作为次级气流的非热交换风进入贯流风道中， 在实现 出风风量增大的同时， 获得温度适宜的出风。 而且， 各个环形导风体优选采用 径向截面是不完全相同的曲线面， 以保证各热交换风风道不同方向上出风的均 匀性。 各个环形导风体的径向截面的具体结构请参考图 4至图 6所示及下述对 各图的描述。
在该实施例中， 通过采用多个单体部件形式的环形导风体组合构成空调送 风装置 1， 便于根据送风要求灵活控制每个环形导风体的结构， 方便地加工出 结构不同的各环形导风体， 以保证送风的均匀性和送风速度。 而且， 由于每个 环形导风体为单体部件， 可以灵活选择整个空调送风装置 1在空调中的装配方 式， 进而提高了空调送风装置 1的适用范围和空调的生产效率。 而且， 空调送 风装置 1中采用径向截面为曲线面的各环形导风体构成热交换风风道， 不仅利 于热交换风风道周向方向出风均匀， 而且能够有效地对热交换风进行导向， 使 得气流在翻转的同时实现加速， 降低了气流的总压损， 能够以较低的噪音导流 出较高的热交换风， 提高了送风装置的送风性能。
在将空调送风装置 1装配到空调中时， 后端环形导风体 12与空调的后背 板 3进行固定，第一中间环形导风体 13先与前端环形导风体 11通过螺钉固定， 然后将固定有第一中间环形导风体 13的前端环形导风体 11固定到空调的前面 板 2上。固定到位之后，前端环形导风体 11的混合风出口 111作为整个空调送 风装置 1的出风口，将与前面板 2上的混合风出口 21进行封闭装配；而后端环 形导风体 12中的非热交换风进口 122作为整个空调送风装置 1的非热交换风进 风口， 将与后背板 3上的非热交换风进口 31进行封闭装配。
在空调中采用上述结构的空调送风装置 1之后， 空调运行时， 室内风进入 空调内部， 在风机 6的作用下， 加速吹向热交换器 5进行热交换。 热交换后的 热交换风从内部风道 4吹向空调送风装置 1、并经第一环形热交换风风道 14和 第二环形热交换风风道 15 进入贯通风道， 进而经贯通风道从前端环形导风体 11上的混合风出口 111及前面板 2上的混合风出口 21吹出。 由于热交换风从 面积较大的内部风道 4吹至面积变小的环形热交换风风道中， 使得从环形热交 换风风道吹出的热交换风风速变大， 从而使得相应环形导风体表面压力减小而 在贯通风道内形成负压，空调外部的室内风作为非热交换风，在负压的作用下， 将从后背板 3上的非热交换风进口 31及后端环形导风体 12的非热交换风进口 122 进入贯通风道， 并与环形热交换风风道所吹出的热交换风形成混合风后一 起送到室内。 这样的混合风较为柔和， 吹到用户身上会感觉更加舒适， 提高了 用户舒适性体验效果。 同时， 利用空气送风装置 1所产生的负压作用吸入部分 外部未热交换的风参与到空调最后的出风中， 增大了空调的整体进风量， 加快 了室内空气的流动， 进一歩提高了室内空气的整体均匀性。
在该实施例， 作为优选实施方式， 前面板 2上的混合风出口 21和后背板 3 上的非热交换风进口 31的形状为圆形；相应的，空调送风装置 1中各环形导风 体的形状为圆环形。 但不局限于此， 还可以设计成其他形状的组合， 如椭圆形 和椭圆环、 正多边形和正多边形环等， 也都能实现本发明的技术目的。 图 4示出了图 3中前端环形导风体 11的具体结构。 如图 4的径向截面结 构示意图所示意， 前端环形导风体 11包括前后两段， 靠近其前开口、也即混合 风出口 111的前段为外扩的混合风导流部 113，靠近其后开口、也即进风口 112 的后段为热交换风导流部 114。 混合风导流部 113作为对热交换风与非热交换 风混合而成的混合风进行导流的主要部件， 其径向截面中的顶面轮廓线 1131 和底面轮廓线 1132 优选均为直线段或近似于直线的微弧段 （曲率半径较大的 弧）。热交换风导流部 114作为对热交换风进行导流的主要部件，其径向截面中 的顶面轮廓线 1141和底面轮廓线 1142均是曲率半径为 40-100mm的弧线段。混 合风导流部 113与热交换风导流部 114的顶面轮廓线及底面轮廓线依次连接， 并通过端部封闭线 1133和 1143形成封闭区域， 最终获得径向截面为流线型的 曲线面。 而且， 对热交换风导流部 114的顶面轮廓线 1141和底面轮廓线 1142 进行封堵的端部封闭线 1143优选为圆弧段，以保证热交换风顺利进入到热交换 风风道内， 避免产生涡流。 而且， 综合考虑送风性能、 结构强度及美观性， 混 合风导流部 113的表面宽度 W1是热交换风导流部 114的表面宽度 W2的 0. 9-1. 1 倍， 优选两者宽度相等。 例如， 在该实施例中， W1=W2=90. 7mm。
图 5示出了图 3中后端环形导风体 11的具体结构。 如图 5的径向截面结 构示意图所示意， 后端环形导风体 12也包括有前后两段， 靠近其前开口、也即 出风口 121的前段为导流部 123， 靠近其后开口、 也即非热交换风进口 122的 后段为翻边安装部 124。 导流部 123作为对热交换风进行导流的主要部件， 其 径向截面中的顶面轮廓线 1231和底面轮廓线 1232均是曲率半径为 50-80mm的 弧线段。 在该实施例中， 曲率半径为 61. 4mm。 而翻边安装部 124作为主要的安 装部件， 其径向截面的顶面轮廓线 1241和底面轮廓线 1242均是与该后端环形 导风体 12的轴线方向相垂直的直线段。导流部 123与安装部 124的顶面轮廓线 及底面轮廓线依次连接， 并通过端部封闭线 1233和 1243进行封闭而形成封闭 区域， 最终获得径向截面为流线型的曲线面。优选的， 端部封闭线 1233为圆弧 段， 以保证热交换风顺利进入到热交换风风道内， 避免产生涡流。 而且， 安装 部 124的表面宽度 W3不宜过大，但也不能太小，优选其宽度为导流部 123表面 宽度 W4的 15-30%， 更优选的值是 25%。
图 6示出了图 3中第一中间环形导风体 13的具体结构。 如图 6的径向截 面结构示意图所示意，在具有第一中间环形导风体 13的空调送风装置 1中，第 一中间环形导风体 13位于后端环形导风体 12及前端环形导风体 11之间，且第 一中间环形导风体 13的表面宽度（W5+W6 )不大于前端环形导风体 12中的热交 换风导流部 114的表面宽度 W2。例如，在该实施例中， W2为 90. 7mm,而（W5+W6 ) =61. 3mm 0 第一中间环形导风体 13的径向截面中的底面轮廓线 133是曲率半径 为 50-80mm之间的一弧线段， 而其顶面轮廓线 134至少包括有靠近第一中间环 形导风体 13前开口、 也即出风口 131的第一弧线段 1341和靠近该第一中间环 形导风体 13后开口、 也即进风口 132的第二弧线段 1342。 顶面轮廓线 134与 底面轮廓线 133通过端部封闭线 1343和 1344进行封堵， 形成流线型封闭结构 的曲线面。 其中， 端部封闭线 1343和 1344均为弧线段。 在该实施例中， 第一 弧线段 1341的曲率半径大于底面轮廓线 133的曲率半径， 而第二弧线段 1342 的曲率半径小于该底面轮廓线 133的曲率半径。 例如， 底面轮廓线 133的曲率 半径为 60. 2mm， 第一弧线段 1341的曲率半径为 115. 3mm， 而第二弧线段 1342 的曲率半径为 51. 4mm。 并且， 第二弧线段 1342与底面轮廓线 133之间的距离 大于第一弧线段 1341与底面轮廓线 133之间的距离，从而形成前细后粗的结构。
各环形导风体采用上述结构的径向截面之后， 能够最大程度降低压损， 进 而降低空调送风装置 1送风过程中的噪音。
除了采用上述三个环形导风体构成空调送风装置 1之外， 还可以在前端环 形导风体 11和后端环形导风体 12之间设置更多个中间环形导风体。 每个中间 环形导风体可以参考上述第一中间环形导风体 13的径向截面来设计。
以上实施例仅用以说明本发明的技术方案， 而非对其进行限制； 尽管参照 前述实施例对本发明进行了详细的说明， 对于本领域的普通技术人员来说， 依 然可以对前述实施例所记载的技术方案进行修改， 或者对其中部分技术特征进 行等同替换； 而这些修改或替换， 并不使相应技术方案的本质脱离本发明所要 求保护的技术方案的精神和范围。
