Abstract

L'invention concerne un matériel climatiseur d'intérieur, qui supporte un panneau mobile de manière rotative près d'un orifice d'aspiration de manière articulée et, dont l'espace entre ce panneau mobile et la périphérie de l'orifice d'aspirations peut être rétréci. Dans ce matériel climatiseur d'intérieur (2), un premier axe (63) ou l'axe de rotation central du panneau mobile (24) est placé hors du voisinage de la limite entre un corps (20) et le panneau mobile (24). Lorsque le panneau mobile (4) ouvre un orifice d'aspiration (20a), cet orifice d'aspiration (20a) est ouvert alors que l'espace est simultanément agrandi entre le corps (20) et le panneau mobile (24), de sorte que le corps (20) et le panneau mobile (24) n'interfèrent pas. Par conséquent, l'espace au niveau de la limite entre le corps (20) et le panneau mobile (24) au moment où ce panneau mobile (24) ferme l'orifice d'aspiration (20a) est rétréci pour améliorer le design.
