Abstract

Climatiseur, comprenant : un ensemble de base (101) ; un ensemble conduit d'air (301) comprenant un boîtier inférieur (310) et des roues (320) disposées sur le boîtier inférieur (310) ; un moteur de ventilateur (141) disposé sur l'ensemble de base (101) servant à entraîner les roues (320) à tourner. L'ensemble conduit d'air (301) peut être entièrement détaché de l'ensemble de base (101) dans le cas où le moteur de ventilateur (141) dans l'ensemble de base (101) n'est pas détaché. Selon le climatiseur, il n'est pas nécessaire de détacher les roues (320) ni le moteur de ventilateur (141) ensemble lorsque les roues (320) sont nettoyées, un nettoyage plus facile est mis en oeuvre et il n'est pas facile d'endommager un manchon de moteur et l'arbre de sortie du moteur.
