Abstract

Le dispositif de ventilateur soufflant selon la présente divulgation est installé dans une cabine (2) comportant un espace de salle de séjour (3), un orifice d'entrée pour fournir de l'air à l'espace de salle de séjour (3), et un orifice d'échappement pour évacuer l'air de l'espace de salle de séjour (3). Le dispositif de ventilateur soufflant comprend : une pluralité de buses supérieures (14a à 14d) qui sont agencées de manière décalée par rapport à une plaque supérieure (6), chacune des buses supérieures (14a à 14d) comportant un orifice de sortie en forme de fente par lequel sort de l'air soufflé s'écoulant le long de la direction allant de la plaque supérieure (6) à une plaque de plancher (4) ; et un ventilateur soufflant pour souffler l'air aspiré par l'orifice d'entrée d'air vers la pluralité des buses supérieures (14a à 14d). La pluralité des buses supérieures (14a à 14d) sont disposées côte à côte avec un espace prescrit entre elles de sorte que les orifices de sortie sont positionnés sur le même plan, et sont conçues de sorte que, lorsque des buses supérieures (14a et 14d) parmi la pluralité des buses supérieures qui sont adjacentes à des panneaux latéraux (5) sont des premières buses supérieures, et des buses supérieures (14b et 14c) parmi la pluralité des buses supérieures qui sont adjacentes aux premières buses supérieures sont des secondes buses supérieures, le volume d'air soufflé par les orifices de sortie des secondes buses supérieures est supérieur à celui soufflé par les orifices de sortie des premières buses supérieures.
