Abstract

La présente invention concerne un dispositif de soufflage d'air comportant une sortie d'air (11), une partie (12) formation de passage qui présente une première paroi (121) et une seconde paroi (122) faisant face à la première paroi, et forme un passage d'air qui se prolonge vers le côté amont de l'écoulement d'air de la sortie d'air, et un élément de déviation (13) d'écoulement d'air équipant le passage d'air. L'élément de déviation d'écoulement d'air est conçu de sorte qu'un écoulement d'air à grande vitesse se produit dans un premier passage (12a) entre l'élément de déviation d'écoulement d'air et la première paroi, et un écoulement d'air à basse vitesse se produit dans un deuxième passage (12b) entre l'élément de déviation d'écoulement d'air et la seconde paroi. Une partie du côté sortie d'air de la première paroi constitue une paroi de guidage (14) servant à guider l'écoulement d'air à grande vitesse. Le premier passage et le second passage, dans la direction dans laquelle la première paroi et la seconde paroi se font face, présentent une première largeur (L1) de passage et une seconde largeur (L2) de passage. Le rapport entre la première largeur de passage et la seconde largeur de passage est différent entre une première position et une seconde position, qui sont différentes l'une de l'autre, dans la direction longitudinale du passage d'air. Grâce à cette configuration, la forme de l'écoulement d'air soufflé par la sortie d'air peut être rendue différente de la forme de l'écoulement d'air lorsque le rapport entre la première largeur de passage et la seconde largeur de passage est uniforme sur toute la direction longitudinale du passage d'air.
