Abstract

La présente invention concerne un climatiseur. Le climatiseur selon la présente divulgation comprend : un boîtier qui forme un orifice d'aspiration et un orifice d'évacuation ; un ventilateur soufflant situé à l'intérieur du boîtier ; un guide d'évacuation qui forme un trajet de circulation d'évacuation par lequel de l'air amené à circuler par le ventilateur soufflant est guidé vers le côté avant inférieur ; une première aube et une seconde aube qui guident l'air ; une première liaison et une deuxième liaison qui sont reliées à chacun du boîtier et de la première aube ; une troisième liaison qui est reliée à chacune de la première liaison et de la seconde aube ; et un moteur pour faire tourner la première liaison. Lorsque la première aube est située à une première position au niveau de laquelle la première aube guide vers l'avant l'air évacué de l'orifice d'évacuation, l'extrémité avant de la première aube est située devant une paroi avant du boîtier.
