To improve comfort of an occupant.SOLUTION: In a vehicle blowing device 10, a horizontal surface 55a and a rear side inclined surface 55 are provided as guide parts on the rear side of a blower duct 12a in a vehicle traveling direction with respect to the head of an occupant and at the front side in the vehicle traveling direction with respect to an air blowout port 40. A primary air stream blown out from the blowout port 40 is attracted by the Coanda effect to the horizontal surface 55a and the rear side inclined surface 55 to flow along the horizontal surface 55a and the rear side inclined surface 55. Along with the primary air stream being blown out from the blowout port 40, a secondary air stream is attracted to the horizontal surface 55a and the rear side inclined surface 55 from the vicinity of the horizontal surface 55a and the rear side inclined surface 55 outside the blower duct 12a, and the attracted secondary air stream and the primary air stream flowing along the horizontal surface 55a and the rear side inclined surface 55 are sent to the head of the occupant.SELECTED DRAWING: Figure 1
【課題】乗員への快適性を向上する。【解決手段】車両用送風装置10では、送風ダクト12aのうち乗員の頭部に対して車両進行方向後側で、かつ空気吹出口40に対して車両進行方向前側には、水平面55a、後側傾斜面55がガイド部として設けられている。吹出口40から吹き出される一次空気流がコアンダ効果によって水平面55a、後側傾斜面55に引き寄せられて水平面55a、後側傾斜面55に沿って流れる。吹出口40から一次空気流が吹き出されることに伴って送風ダクト12aの外側において水平面55a、後側傾斜面55の周辺から二次空気流を水平面55a、後側傾斜面55に引き寄せ、この引き寄せられた二次空気流と水平面55a、後側傾斜面55に沿って流れる二次空気流とが乗員の頭部に送られる。【選択図】図1
