[0034] 需要说明的是： 在本发明实施例的附图中实线箭头用于表示送风过程中的气流 方向； 虚线箭头用于表示所述扫风叶片的受力方向。
[0035] 参照图 4~图8， 图 4为本发明提供的一种空调器扫风装置的一个具体实施例， 本 实施例所述的空调器扫风装置包括转轴 1和多个扫风叶片 2， 转轴 1设于空调器的 出风口 31处， 并与空调器的机壳 3转动连接， 多个扫风叶片 2沿所述转轴 1的轴向 同向倾斜的固定于转轴 1上， 各扫风叶片 2相对于转轴 1同向倾斜设置， 且当气流 送至扫风叶片 2吋， 所述气流可推动扫风叶片 2及转轴 1绕转轴 1的轴线旋转。
[0036] 本发明实施例提供的空调器扫风装置， 多个扫风叶片 2沿转轴 1的轴向并列的固 定于转轴 1上， 且各扫风叶片 2相对于转轴 1同向倾斜设置， 由于当气流送至扫风 叶片 2吋， 所述气流可推动扫风叶片 2及转轴 1绕转轴 1的轴线旋转， 在此转动过 程中， 由于多个扫风叶片 2均固定于转轴 1上， 使得相邻两扫风叶片 2间形成的风 道的方向会随扫风叶片 2的转动而发生改变， 如图 7和图 8所示， 其中， 图 8中的 扫风叶片 2为图 7中的扫风叶片 2在转动 180°后的状态， 送风方向如实线箭头所示 ， 可以看出， 在扫风叶片 2的转动过程中， 由于相邻两扫风叶片 2相对静止， 使 得相邻两扫风叶片 2间形成的风道的方向会随扫风叶片 2的转动而发生改变， 从 而可通过所述风道的引导使送风方向随扫风叶片 2的转动而改变， 使得可在不需 要专门的驱动装置 （例如步进电机） 驱动的情况下， 利用空调器的送风推动扫 风叶片 2转动， 进而通过扫风叶片 2的转动实现对送风角度的改变。 由于省去了 专门的驱动装置和传动机构， 使扫风装置的结构更加简单， 安装和拆卸更加方 便， 整个装置的成本得以降低。 由此， 可简化结构， 降低成本。
[0037] 参照图 9和图 10， 扫风叶片 2的长轴线 21与垂直于转轴 1的平面形成第一夹角 a， 短轴线 22与转轴 1的轴线形成第二夹角 b， 第一夹角 a和第二夹角均为锐角 b， 其中 ， 长轴线 21为通过扫风叶片 2的轮廓线上距离最远的两点的直线， 短轴线 22为通 过长轴线 21—侧的轮廓线中点和另一侧的轮廓线中点的直线， 由于空调器的送 风通常沿垂直于转轴 1的平面到达扫风叶片 2， 因此， 当空调器的送风到达扫风 叶片 2吋， 扫风叶片 2与到达扫风叶片 2的气流呈一定夹角， 使得空调器的送风会 对扫风叶片 2的表面产生作用力 F， 如图 10所示， 根据空气动力学的原理， 作用 力 F可分解出沿扫风叶片 2切向的分力 f， 切向分力 f和转轴 1间产生使扫风叶片 2转 动的力矩， 可驱动扫风叶片 2带动转轴 1转动。 从而可通过气流推动扫风叶片 2及 转轴 1转动。
[0038] 由于第一夹角 a和第二夹角 b的角度影响气流与扫风叶片 2的夹角， 从而影响扫 风叶片 2切向的分力 f的大小， 为了便于扫风叶片 2被气流推动， 可使第一夹角 a在 20°~60°之间； 第二夹角 b在 30°~80°之间。
[0039] 为了使扫风叶片 2更加容易转动， 从而便于稳定、 持续的改变送风方向， 扫风 叶片 2的两侧表面分别设置有凹面， 所述两侧表面的凹面分别位于转轴 1两侧。 在不改变扫风叶片 2整体尺寸的情况下， 通过所述凹面增大了扫风叶片 2与气流 的接触面， 从而增大了扫风叶片 2的受力面， 使得在送风功率较小的情况下， 扫 风叶片 2仍能被气流推动而转动， 有利于确保稳定、 持续的改变送风方向， 进一 步提高用户的舒适度。
[0040] 具体地， 扫风叶片 2的凹面可为以下两种结构：
[0041] 如图 11所示， 所述凹面为扫风叶片 2的两侧表面直接凹陷形成的凹型结构， 且 为了避免因在所述凹面里存在棱角而影响气流送出， 优选所述凹面为光滑的曲 面， 从而保证气流的顺利送出。 [0042] 或者， 如图 12所示， 扫风叶片 2的两侧表面上分别设有凸棱 23， 所述凹面为扫 风叶片 2两侧表面与各自的凸棱 23形成的凹型结构， 送风吋， 气流沿扫风叶片 2 的侧面吹至凸棱 23上， 为保证气流的顺畅送出， 凸棱 23的受风面为光滑的曲面 ， 且为了简化结构， 凸棱 23可与扫风叶片的两侧面一体成型。
[0043] 扫风叶片 2的轮廓的形状可采用圆形、 方形、 椭圆形或其他形状， 由于出风口 3 1的尺寸及形状固定， 为了避免出风口 31对扫风叶片 2产生干涉， 扫风叶片 2不能 过大， 同吋， 为了保证扫风叶片 2能较好的引导气流方向， 扫风叶片 2的尺寸应 较大， 便于气流与扫风叶片 2的两侧表面接触， 从而引导气流方向。 而椭圆在其 长轴方向的长度较大， 使得相邻两扫风叶片间 2形成的风道较长， 便于引导气流 放方向， 同吋， 避免了为便于引导气流而增大扫风叶片 2的尺寸， 因此， 优选扫 风叶片 2的轮廓形状为椭圆， 并且为了使扫风叶片 2在转轴 1两侧的部分能对称受 力， 使扫风叶片 2的转动更加平稳， 可使转轴 1穿过所述椭圆的中心 （几何中心 ) ， 从而使扫风叶片 2的转动中心与其几何中心重合， 使扫风叶片 2的转动过程 更加平稳。
[0044] 为了避免转轴 1中部因缺乏支撑而弯曲变形， 可在转轴 1中部设置支撑架 5， 支 撑架 5固定于机壳 3上， 并与转轴 1转动连接， 支撑架 5可在不影响转轴 1转动的情 况下为转轴 1提供支撑。
[0045] 为了使各扫风叶片 2能均匀的引导送风方向， 位于支撑架 5同一侧的扫风叶片 2 均匀分布。
[0046] 此外， 可将各扫风叶片 2的位于转轴 1同侧的凹面朝向同一方向， 各扫风叶片 2 上朝向同一方向的凹面的位置、 形状和大小均相同， 保证当送风到达扫风叶片 2 吋， 承受送风产生的作用力的凹面朝向同一方向， 从而提高扫风叶片 2的受力方 向的一致性。
[0047] 扫风叶片 2可与转轴 1分别制造， 而后连接， 也可以直接一体成型， 为了简化结 构和安装过程， 扫风叶片 2与转轴 1可采用一次注塑成型， 从而有利于缩短空调 器扫风装置的制造和安装的吋间。
[0048] 参照图 13， 转轴 1与机壳 3的连接方式有多种， 例如： 可在转轴 1的两端设置轴 承或轴套， 通过螺钉将所述轴套或轴承与机壳 3连接； 或者在转轴 1的两端设置 轴承或轴套， 将所述轴套或轴承镶嵌于机壳 3内。 为了简化结构， 减少连接件， 便于安装和拆卸， 可在转轴 1的两端设置轴套 4， 轴套 4与转轴 1转动连接， 轴套 4 边缘设有卡爪 41， 机壳 3上与轴套 4对应的位置设有安装孔 （图中未示出） ， 轴 套 4配合设置于所述安装孔内， 机壳 3上与卡爪 41对应的位置设有卡孔 （图中未 示出） ， 卡爪 41卡接于所述卡孔内。
[0049] 本发明实施例还提供了一种空调器， 包括上述任一技术方案所述的空调器扫风 装置。 由于在本实施例所述的空调器中所使用的空调器扫风装置与上述空调器 扫风装置的各实施例中所述的空调器扫风装置相同， 因此， 因此二者能解决相 同的技术问题， 并达到相同的预期效果。
[0050] 关于本发明实施例所述的空调器的其他构成等已为本领域的技术人员所熟知， 在此不再详细说明。
[0051] 在本说明书的描述中， 具体特征、 结构、 材料或者特点可以在任何的一个或多 个实施例或示例中以合适的方式结合。
[0052] 以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到变化 或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范围应以所 述权利要求的保护范围为准。
