Abstract

L'invention porte sur un climatiseur, qui comprend, à l'intérieur d'une unité intérieure (1), un échangeur de chaleur (3), un bâti de base (2) qui supporte l'échangeur de chaleur (3) et qui forme un trajet de soufflage d'air, un ventilateur (5) qui est disposé dans un espace formé par l'échangeur de chaleur (3) et le bâti de base (2), et un moteur de ventilateur (4) qui entraîne en rotation le ventilateur (5), et une section de coin à la partie inférieure du bâti de base (2) étant formée à partir d'un élément de coin détachable (6). Le climatiseur est configuré de telle sorte que le raccord entre l'élément de coin (6) et le bâti de base (2) est situé dans une position au-dessus de l'extrémité supérieure du moteur de ventilateur (4) et de telle sorte qu'une section de prise (10) venant en prise avec le bâti de base (2) est disposée sur la surface interne de la paroi latérale de l'élément de coin (6). En résultat de la configuration, même si l'échangeur de chaleur a une grande longueur globale, le moteur de ventilateur peut être retiré et l'élément de coin est moins susceptible d'être disloqué à partir du bâti de base.
