Description

设有气流分配组件的空调送风装置 技术领域
本发明属于空气调节技术领域， 具体地说， 是涉及一种设有气流分配组件 的空调送风装置。
背景技术
现有立式空调送风时， 热交换器热交换后的风直接在内部风扇的作用下、 从空调上开设的出风口吹出， 且所吹出的风全部是热交换风。 一般的， 在热交 换器与出风口之间不设置额外的送风装置。 这种空调送风的一个缺点是由于送 出风全部是热交换风， 风量较少， 室内风循环速度慢； 另一个缺点是送出的风 不够柔和， 尤其是在制冷模式下， 所吹出的凉风直接吹到用户身上， 用户感觉 不舒适。
为解决上述问题， 本申请人曾提出了一种可以应用在空调上的空调送风装 置， 空调送风装置包括有环形罩体， 在环形罩体中间形成有贯穿环形罩体的贯 通风道， 在环形罩体壁上形成环形开口， 在环形开口上设置若干环形导流片， 相邻环形导流片之间形成环形出风风道。 在空调热交换器与空调壳体的出风口 之间设置该空调送风装置后，不仅可以增大空调的进风量、加速室内空气流动， 而且能够提高空调出风的柔和性， 改善用户舒适性体验效果。 但是， 由于环形 导流片及环形出风风道均形成在一个环形罩体上， 不便于灵活选择和控制环形 导流片及出风风道的结构， 适用范围较窄。而且， 由于空调风扇由下向上送风， 热交换风在进入环形出风风道时周向方向上不均匀， 使得环形出风风道下端风 量较大， 而左右两侧风量较小， 进而导致空调送风装置所送出的风在整个周向 方向上分布不均匀， 影响用户舒适性使用效果。
发明内容
本发明的目的是提供一种设有气流分配组件的空调送风装置， 利用气流分 配组件对送风装置周向方向上的进风进行分配， 以提高送风均匀性。 为实现上述发明目的， 本发明采用下述技术方案予以实现：

如上所述的空调送风装置， 所述气流分配组件以将进入所述环形热交换风 风道的所述热交换风沿所述环形热交换风风道周向方向均匀分配的结构设置在 所述环形热交换风风道内。
如所述的空调送风装置， 在所有所述环形热交换风风道中均设置有所述气 流分配组件。
如上所述的空调送风装置， 所述环形导风体至少为三个， 所述气流分配组 件设置在位于中间位置的所述环形导风体上、并向由该环形导风体所形成的内、 外两个所述环形热交换风风道中延伸。
优选的， 所述位于中间位置的所述环形导风体与设置在其上的所述气流分 配组件一体成型。
如上所述的空调送风装置， 所述气流分配组件包括有多个气流分配板， 所 述多个气流分配板在所述环形热交换风风道的周向方向上、 沿所述热交换风送 风风向左右对称分布。
如上所述的空调送风装置， 所述多个气流分配板为具有相同弯曲方向的弯 曲分配板，且多个所述弯曲分配板的弯曲方向与所述热交换风的送风方向相逆。
与现有技术相比， 本发明的优点和积极效果是： 1、 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。
2、 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。
3、 通过在热交换风风道内设置气流分配组件， 可利用气流分配组件对进 入送风装置的热交换风在周向方向上进行分配， 从而提高了送风装置的送风均 匀性。

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。
然后， 简要说明本发明的设计思路： 对于能够将空调热交换器交换后的热 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， 虽然能够增 大送风量、 保证出风温度的适宜， 但是， 由于空调内的风扇位于下方， 热交换 器交换后的热交换风自下而上送风， 使得在空调中放置上这样的空调送风装置 之后，热交换风在风扇的吹动下大多从空调送风装置下部进入空调送风装置中， 而左右两侧及上部进风量相对较少， 使得空调送风装置在周向方向上所送出的 风不够均匀。 为解决该问题， 可在空调送风装置的环形热交换风风道中设置对 来自空调热交换器、 并进入该环形热交换风风道的热交换风进行分配、 尤其是 进行均匀分配的气流分配组件。 更优选的， 在空调送风装置的所有环形热交换 风风道中均设置气流分配组件， 使得热交换风在周向方向上均匀进入热交换风 风道中， 从而提高空调送风装置的送风均匀性。
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的立体组装结构示意图、 图 3的 爆炸结构示意图及图 4的后视结构示意图所示。
如图 2、 图 3及图 4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， 分别为混合风出口 111和进风口 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， 分别为出风口 121和非热交换风进口 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。在第一中 间环形导风体 13上设置有向第一环形热交换风风道 14和第二环形热交换风风 道 15中延伸的气流分配组件 16。 而且， 为方便加工， 气流分配组件 16优选与 第一中间环形导风体 13—体成型。 当然， 也可以是分体成型， 然后将气流分配 组件 16安装固定在第一中间环形导风体 13上。
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。热交换风在气流分配组件 16的分 配下，沿周向方向均匀地进入第一环形热交换风风道 14和第二环形热交换风风 道 15内，再经热交换风风道进入贯通风道，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 起送出到室内。
在一定风机转速下、 对立式空调进行风量测试及温度检测， 采用上述空调 送风装置 1之后， 引入的非热交换风为热交换风风量的 1. 1倍左右， 获得的混 合风风量为热交换风风量的 2. 1倍左右， 比同状况下、 未采用空调送风装置 1 的空调送风相比， 空调出风增加了 1. 1倍左右。 而且， 如果室温为 28°C左右， 未采用空调送风装置 1的空调所吹出的风为热交换风， 其温度为 14°C左右； 而 使用空调送风装置 1之后， 空调所送出的混合风为 19°C左右， 混合风的温度更 符合人体体感温度舒适性的要求。 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。 而且， 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。
气流分配组件 16的具体结构请参考图 4的后视图所示意， 该实施例的气 流分配组件 16采用多个气流分配板来实现。 该实施例的气流分配组件 16共包 括有四对、 八个气流分配板， 分别为主气流分配板 161和 162、 第一辅助气流 分配板 163和 164、第二辅助气流分配板 165和 166、第三辅助气流分配板 167 和 168。 所有气流分配板为具有相同弯曲方向的弯曲分配板， 且每个气流分配 板的表面均为弧形曲线面， 可以有效地引导风向， 并降低气流在分流过程中的 压损和噪音， 实现低噪音前提下的高速送风。 这四对气流分配板以主气流分配 板 161和 162在下、第一辅助气流分配板 163和 164、第二辅助气流分配板 165 和 166及第三辅助气流分配板 167和 168依次往上的顺序左右对称分布在第一 环形热交换风风道 14和第二环形热交换风风道 15的周向方向上。 也即沿自下 而上的热交换风送风方向上，空调送风装置 1的左侧（以后视图方向而言的左、 右侧） 自下而上设置有主气流分配板 161、第一辅助气流分配板 163、第二辅助 气流分配板 165和第三辅助气流分配板 167，而主气流分配板 162、第一辅助气 流分配板 164、 第二辅助气流分配板 166和第三辅助气流分配板 168以左右对 称的形式设置在空调送风装置 1的右侧。 而且， 各气流分配板的弯曲方向与热 交换风送风方向相逆。 也即， 热交换风送风方向自下而上， 则各气流分配板的 弯曲反向将是逆向送风方向， 即如图 4所示的逆时针方向弯曲。
通过在热交换风风道中设置呈放射状对称分布的多个弯曲气流分配板构 成的气流分配组件 16，可以利用主气流分配板 161和 162将来自热交换器的热 交换风分成左、 中、 右三部分， 而左、 右两侧的热交换风又可以被各辅助气流 分配板再次分流， 最终实现了空调送风装置 1的热交换风风道在周向方向上进 风及出风的均匀性， 提高了空调送风装置 1的送风均匀性。
当然， 气流分配组件 16 除了采用多个弯曲气流分配板来实现之外， 还可 以采用其他的结构， 只要能保证将来自热交换器 5的热交换风在周向方向上进 行均匀分配即可。
在该实施例的空调中， 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。 虽然该实施例中的空调送风装置 1具有三个环形导风体， 但并不局限于这 样的三个， 还可以是仅有前端环形导风体 11和后端环形导风体 12这两个环形 导风体， 两个环形导风体形成一个热交换风风道。 此结构下， 可以在该热交换 风风道内设置与其中一个环形导风体相固定的气流分配组件来实现对热交换风 的分配。
当然， 还可以是更多个， 例如， 除了前端环形导风体 11 和后端环形导风 体 12之外， 还包括有两个及两个以上的第一中间环形导风体 13， 构成具有四 个或四个以上环形导风体的空调送风装置。 该结构下， 将会形成三个或三个以 上的热交换风风道。 在这样的空调送风装置中， 优选在所有热交换风风道中均 设置气流分配组件。 而且， 为简化结构， 可以两个热交换风风道共用一个气流 分配组件， 也即将气流分配组件设置在位于中间的环形导风体上、 并向由该环 形导风体所形成的内、 外两个所述环形热交换风风道中延伸。
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。
