摘要： A centrifugal multi-blade fan has multiple blades about a rotational shaft and draws in air along the rotational shaft and then blows the air approximately perpendicular to the rotational shaft to reduce wind noise. A scroll casing encloses the multi-blade fan and defines a scroll-shaped airflow passage for directing the air blown from the multi-blade fan. The scroll casing has an intake opening and an outlet opening at a scroll end, in a downstream scroll casing portion. The scroll casing expands such that a flow passage cross-sectional area on the airflow downstream side is larger than that on an airflow upstream side. A ratio of a blade length to a diameter of the multi-blade fan is greater than or equal to 0.12, and an outer scroll casing radius, relative to the rotational axis, increases as a logarithmic spiral, its expansion angle being from 3.3° to 4.8°.
摘要翻译：离心式多叶片风扇具有围绕旋转轴的多个叶片，并沿着旋转轴吸入空气，然后大致垂直于旋转轴吹送空气以减少风噪声。涡旋壳体包围多叶片风扇并且限定用于引导从多叶片风扇吹出的空气的涡旋状气流通道。涡旋壳体在下游涡旋壳体部分中具有在涡旋端处的进气开口和出口。涡旋壳体膨胀，使得气流下游侧的流路横截面积大于气流上游侧的流路截面积。叶片长度与多叶片风扇的直径的比率大于或等于0.12，并且相对于旋转轴线的外涡旋壳体半径随着对数螺旋而增加，其膨胀角为3.3°至 4.8°。

摘要： Each of blades of a multi-blade centrifugal blower is provided with a taper portion, which is arranged at an inside periphery at least at the side of one rotation-shaft-direction end of the blade and tapers from the side of other rotation-shaft-direction end of the blade toward the side of the one rotation-shaft-direction end. The taper portion is positioned at a rotation-direction front side with respect to a back portion disposed at the side of the other rotation-shaft-direction end of the blade. Each of inlet angles throughout the taper portion is set in a range from 55° to 74°. Therefore, air flowing speed at an outlet of an impeller wheel is uniformed throughout the blade width. Work capacity and efficiency of the impeller wheel are increased, while noise is reduced.
