空调器风道装置及使用该风道装置的空调器 技术领域
本发明属于空调技术领域, 具体涉及空调器风道装置及使用该风道装置的空调 器。 背景技术
众所周知, 风道装置常用于空调系统以及其它通风装置中。 如对空调系统而言, 空调风道是与整个空调性能高低威威相关的部分, 而风道装置产生的风量大小与换 热效率直接相关, 其电机消耗也与空调能量消耗有直接关系, 同时, 室内机噪音也 一直备受使用者关注。
随着空调能效需求的一再提高,原有风道装置已逐渐不能满足风量提升的需要, 限制了换热效率与能效比的提高。 若是通过增加风扇转速来实现风量的增长, 这种 方式下风量的提升往往伴随着电机功率的增加以及噪音的升高。 风扇吸力面靠近后 缘时, 表面压力过低会导致气体与风叶表面之间分离, 并可能发生回流以及一些涡 流的产生, 这些现象对风量有着不良影响, 阻碍气流在叶片表面上顺畅流动, 浪费 风叶做功提供的能量, 从而降低风量; 此外, 气体的湍流运动与涡流也是气动噪声 的主要来源之一。 由此可见, 通过提高风量来提高空调器的性能是一种经济高效的手段, 但是实 际实施难度很大。 而对风道装置的结构及降低噪音性能方面作进一步的改进, 是本 领域的研发重点。 发明内容
本发明的目的在于提供一种空调器风道装置及空调器,通过改进蜗壳风道结构, 在保持噪音不变的同时提高空调器室内侧风量, 同时提高空调器的制冷、 制热性能。

所述下蜗壳包括下风叶容纳部和接水盘, 所述下风叶容纳部呈开口朝上的弧线 型, 且下风叶容纳部内轮廓设置有渐扩圆弧倒角, 且沿出风方向, 渐扩圆弧倒角半 径尺寸逐渐增大。
空调器, 其中, 包括有上述的风道装置。
所述空调器为窗式空调器。 综上, 本发明的有益效果是:
本发明的空调器风道装置及空调器, 下蜗壳部分的蜗壳结构风道内轮廓设置有 渐扩圆弧倒角, 且沿出风方向, 倒角半径尺寸越来越大; 通过改进蜗壳结构提高风 量, 有效解决窗式空调器的风量问题, 极大提高空调器的系统性能。 在窗式空调器 上应用, 风量提高约 13 % , 制冷量提高 5 % , EER提高 4 %。 附图说明
