Description

空调器及其导风装置 技术领域
本发明涉及空气调节技术领域，特别涉及一种空调器及其导风装置。
背景技术
随着空调技术的发展，空调器的外形和功能不断更新换代，各种新技术层出不尽。
但是，关于空调器的导风结构的创新结构非常少。现有方案通常都是在出风口处设置导风板和摆叶组，通过导风板调节出风口的一个维度的出风角度，通过摆叶在另一维度进行摆风。现有空调器大量采用上述导风结构，在使用体验和产品外观上趋于一致，难以提升产品档次。
因此，如何在导风结构方面实现创新成为空调行业亟待解决的技术难题。
发明内容
本发明的一个目的是要提供一种创新形的导风装置及应用其的空调器，以提升产品的区分度和用户的使用体验。
本发明的进一步的目的是要使导风装置兼顾导风的指向性和气流的扩散性。
一方面，本发明提供了一种用于空调器的导风装置，用于可转动地安装在所述空调器的出风口处，以引导所述出风口的出风方向；
所述导风装置包括两个板体，两个所述板体间隔设置，且通过至少一个连接部相连；且
在从所述导风装置的进风端至出风端的方向上，两个所述板体的间距先逐渐减小，后逐渐增大。
可选地，至少一个所述板体为中心轴平行于所述导风装置的转动轴线，且凸侧朝向另一所述板体的弧形板。
可选地，至少一个所述板体为中心轴平行于所述导风装置的转动轴线，且凸侧朝向另一所述板体的双曲线形板。
可选地，所述导风装置的转动轴线位于所述两个板体的中心轴的连接面上，且与所述两个所述板体的中心轴的距离相等。
可选地，两个所述板体关于一平面对称且关于所述导风装置的转动轴线呈中心对称。
另一方面，本发明还提供了一种空调器，其包括：
壳体，其内部形成有风道，所述风道的出口构成所述空调器的出风口；和
如以上中任一项所述的导风装置，其设置在所述出风口处，以引导所述出风口的出风方向。
可选地，所述空调器为移动式空调器。
可选地，所述风道由间隔设置的第一风道壁和第二风道壁限定出，所述第一风道壁和所述第二风道壁邻近所述出风口的区段为中心轴线平行于所述导风装置的转动轴线的内凹的圆弧段。
可选地，所述风道具有出风面积小于其上、下游侧的缩颈部，两个所述圆弧段从所述缩颈部的末端向气流下游方向延伸出。
可选地，所述出风口设置在所述壳体前侧顶部并朝前上方敞开；
所述第一风道壁位于所述第二风道壁的后上方，所述第一风道壁的所述圆弧段的圆心角在80°至100°之间，所述第二风道壁的所述圆弧段的圆心角在10°至20°之间，以使所述风道邻近所述出风口的区段为朝前上方敞开的扩口状。
可选地，两个所述板体关于一平面对称且关于所述导风装置的转动轴线呈中心对称；且
所述第一风道壁和所述第二风道壁的所述圆弧段的中心轴线均与所述导风装置的转动轴线重合。
本发明的用于空调的导风装置包括两个间隔设置的板体，在从导风装置进风端至出风端的方向上，两个板体的间距先逐渐减小，后逐渐增大，使得两者之间形成的气流通道先渐缩后渐扩，也就是中间较窄，两开口较宽敞的形状。这种形状的通道对流经其的气流具有增压效果。当该导风装置进行导风时，该气流通道的流出的气流的风力更加强劲，导风指向性很强，送风距离更远。此外，由于两个板体的在出口区段的间距逐渐增大，在导风过程中使气流形成一定程度的扩散。可见，本发明的导风装置不仅新颖独特，还能够兼顾导风指向性和气流的扩散性，如此既能够将气流主体导向最需要冷风/热风的区域，又能够将部分气流扩散地吹出，使得室内其他区域也有冷风/ 热风吹拂。
进一步地，本发明的导风装置使板体为弧形或双曲形，以及限定导风装置的转动轴线位置、对称特性等等，使得先渐缩后渐扩的气流通道的导流性能更好，阻力更小，增压效果更好。
进一步地，本发明的空调器中，使得第一风道壁和第二风道壁邻近出风口的区段为内凹的圆弧段，以及使风道具有缩径部，均使风道临近出风口的区段为扩口状，有利于提高出风静压，提高出风风量。

图1是本发明一个实施例的导风装置50的结构示意图；图2是本发明一个实施例的空调器的结构示意图；图3是图2所示空调器的示意性剖视图。图2和图3示意的是移动式空调器的实施例。
如图1至图3所示，本发明实施例的导风装置50一般性地可包括两个板体51、52和至少一个连接部53。两个板体51、52间隔设置，且通过至少一个连接部53相连，以实现相对位置的固定。例如图1所示，连接部53的数量为两个且均为板状，两个连接部53分别连接于两个板体51、52的长度方向的两端，以使导风装置50整体形成方筒状结构。当然，也可在两个板体的中央部位或者其他部位再设置其他的连接部。当导风装置50进行导风时，两个板体51、52之间的气流通道501能够引导气流方向，两个板体51、 52的外侧表面也同样能够引导气流方向。
空调器内可设置有电机，以用于驱动导风装置50转动。如图1所示，可使连接部53上开设有连接孔，以便于电机的转轴相连。
本发明实施例中，在从导风装置50的进风端A至出风端B的方向上，两个板体51、52的间距先逐渐减小，后逐渐增大。导风装置50进行导风时，气流先流经的一端为进风端A，后流经的一端为出风端B。例如图1，可使导风装置50整体为长条状，使其转动轴线x平行于其长度方向，使其宽度方向的两端分别为进风端A和出风端B。本发明实施例中，从导风装置50进风端A至出风端B的方向上，两个板体51、52的间距先逐渐减小，后逐渐增大，使得两者之间形成的气流通道501先渐缩后渐扩，也就是中间较窄，两开口较宽敞的形状。这种形状的气流通道对流经其的气流具有增压效果。如图3，当该导风装置50进行导风时，该气流通道的流出的气流的风力更加强劲，导风指向性很强，送风距离更远。此外，由于两个板体51、52的在出口区段的间距逐渐增大，在导风过程中使气流形成一定程度的扩散。可见，本发明实施例的导风装置50不仅新颖独特，还能够兼顾导风指向性和气流的扩散性，如此既能够将气流主体导向最需要冷风/热风的区域，又能够将部分气流扩散地吹出，使得室内其他区域也有冷风/热风吹拂。
在从导风装置50的进风端A至出风端B的方向上，优选使两个板体51、52沿曲线延伸，以便是两者间距的变化更加平顺，不会出现骤然的变化导致风力损耗。例如，在一些实施例中，如图1至图3所示，两个板体51、52中，至少一个板体为中心轴平行于导风装置50的转动轴线x，且凸侧朝向另一板体的弧形板。例如可使两个板体51、52均为弧形板。
在另一些实施例中，两个板体51、52中，使至少一个板体为中心轴平行于导风装置50的转动轴线x，且凸侧朝向另一板体的双曲线形板。双曲线为一种圆锥曲线，其标准方程为x 2/a 2-y 2/b 2＝1。例如可使两个板体51、52均为双曲线形板。当然，也可使两个板体51、52中，一个为弧形板，一个为双曲线形板。本实施例使板体51、52为弧形板或双曲线形板，使得先渐缩后渐扩的气流通道501的导流性能更好，阻力更小，增压效果更好。
在一些实施例中，参考图4，导风装置50的转动轴线x位于两个板体51、52的中心轴x1和x2的连接面M上。并且，可使两导风装置50的转动轴线x与两个板体51、52的中心轴的距离相等，即xx1＝xx2。在一些实施 例中，参考图4，导风装置50的两个板体51、52关于一平面N对称且关于导风装置50的转动轴线x呈中心对称。
本发明实施例通过限定导风装置50的转动轴线位置、对称特性等等，使得先渐缩后渐扩的气流通道的导流性能更好，阻力更小，增压效果更好。
本发明另一方面还提供了一种空调器。空调器可为各种形式的空调器，包括壁挂式空调器、立式空调器、吊顶式空调器、移动式空调器等等。
空调器包括壳体10和如以上任一实施例所述的导风装置50。壳体10的内部形成有风道20，风道20的出口构成空调器的出风口12。风道20用于将空调器的调节气流(冷风、热风、新风或净化气流)输送至出风口12处，然后从出风口12向室内环境输送，完成对室内空气的调节。风道20内可设置有风机30，以促进气流的流动。风机30可为贯流风机。导风装置50设置在出风口12处，以引导出风口12的出风方向。
在一些实施例中，如图2和图3所示，空调器为移动式空调器。移动式空调器为整体使空调，其制冷***的各个部件，包括压缩机、冷凝器60、蒸发器40以及节流装置等均设置在移动式空调器的一个壳体10中，壳体10的底部设置有滚轮，以方便移动其位置。
可使压缩机和冷凝器60设置在壳体10的内部空间的下部，使蒸发器40和风道20设置在壳体10的内部空间的上部。可使蒸发器40贴靠于壳体10的后壁内侧，壳体10的后壁可设置有进风口，以用于引入室内空气。蒸发器40方覆盖风道20的进口，以使进入风道20的空气均为与蒸发器40完成换热的气流。
在一些实施例中，如图3所示，风道20由间隔设置的第一风道壁21和第二风道壁22限定出。第一风道壁21和第二风道壁22的邻近出风口12的区段为中心轴线平行于导风装置50的转动轴线x的内凹的圆弧段，分别为圆弧段ab和圆弧段cd。如此，使得风道20临近出风口12的区段为扩口状，有利于提高气流的出风静压，提高出风风量。例如图4所示，可使两个板体51、52关于一平面N对称并且关于导风装置50的转动轴线呈中心对称。并且，使第一风道壁21和第二风道壁22的圆弧段的中心轴线均与导风装置50的转动轴线x重合。
在一些实施例中，如图3和图4所示，可使出风口12设置在壳体10前侧顶部并朝前上方敞开。优选使出风口12所在平面与水平面的夹角在15° 至35°之间，有利于朝前上方送风，以兼顾送风距离和送风范围。第一风道壁21位于第二风道壁22的后上方，第一风道壁21的圆弧段的圆心角在80°至100°之间，第二风道壁22的圆弧段的圆心角在10°至20°之间，以使风道20邻近出风口12的区段为朝前上方敞开的扩口状，从而使出风气流的静压更大，使得风量更大。
在一些实施例中，如图3和图4所示，使得风道20具有出风面积小于其上、下游侧的缩颈部，具体地，缩径部由第一风道壁21的ea段和第二风道壁22的fc段限定出。两个圆弧段ab、cd从缩颈部的末端向气流下游方向延伸出。本实施例通过设置缩径部，均使风道20临近出风口12的区段为扩口状，有利于提高出风静压，提高出风风量。
图4是图3所示空调器风路相关结构的放大视图；图5是图4所示结构在导风装置50转动至平吹角度时的示意图；图6是图4所示结构在导风装置50转动至上吹角度时的示意图；图7是图4所示结构在导风装置50转动至斜吹角度时的示意图；图8是图4所示结构在导风装置50转动至关闭角度时的示意图。
图4至图8示意了导风装置50的几种可选状态。
本发明实施例的空调器具有多种导风效果。
如图4所示，导风装置50处于斜吹角度，利用导风装置50的气流通道501将气流朝前上方引导，使得其吹向更高更远的距离，同时利用两个板体51、52外侧表面将气流向外发散引导，使得气流的覆盖范围更大。
如图5所示，导风装置50处于平吹角度，由于导风装置50与第一风道壁21的距离较近，主要由导风装置50与第二风道壁22之间的间隙进行出风，将气流朝前引导。
如图6所示，导风装置50处于上吹角度，使利用导风装置50的气流通道501将气流朝正上方引导。同时利用两个板体51、52外侧表面将气流朝斜上方引导，以便扩大送风范围。
如图7所示，导风装置50处于斜吹角度，且朝向后上方，以便朝后上方导风。
如图8所示，导风装置50处于关闭角度，导风装置50将出风口12遮蔽。当空调器处于停机状态时，可将导风装置50转动至该关闭角度。
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。
