To provide a duct-type blower capable of efficiently blowing air to a wide range in the cabin of a vehicle.SOLUTION: A duct-type blower includes: a circular cylindrical duct casing 4; a screw member 7 which is inserted in the duct casing 4, and which forms a spiral flow passage 10 in the duct casing 4; and first blower outlets 5 and second blower outlets 6 which are provided in the outer circumference of the duct casing 4, and which blow airflows in the substantially tangential direction of the outer circumference. The first blower outlets 5 and the second blower outlets 6 are continuously but alternately arranged side by side in the lengthwise direction of the outer circumference of the duct casing 4. The blowing directions of the first blower outlets 5 and those of the second blower outlets 6 differ from one another.SELECTED DRAWING: Figure 1
【課題】車室内の広い範囲に効率良く送風することができるダクト型送風装置を提供する。【解決手段】ダクト型送風装置は、円筒型のダクト筐体4と、ダクト筐体4内に挿入され、螺旋流路10をダクト筐体4内に形成するスクリュー部材7と、ダクト筐体4の外周部に設けられ、外周部の略接線方向に空気流を吹き出す第1吹出口5と第2吹出口6と、を備える。第1吹出口5と第2吹出口6は、ダクト筐体4の外周部の長手方向に連続して、交互に並べて配設され、第1吹出口5の吹出方向と第2吹出口6の吹出方向は、相違して形成されている。【選択図】図1
