Abstract

L'invention concerne un climatiseur (20) avec un déflecteur (10). Le déflecteur peut être située à une sortie d'air à partir du climatiseur pour diriger l'air de sortie. Le climatiseur peut comprendre un mécanisme de déplacement (14) pour déplacer le déflecteur par rapport à la sortie d'air de climatiseur. Le déflecteur comprend une multitude de trous et le déflecteur est apte à être positionné par le mécanisme de déplacement dans une position inclinée décalée par rapport à la sortie d'air sous un angle selon lequel l'air de sortie est dévié tout à la fois dans une direction vers le haut et dans une direction vers le bas. Par cela, il peut être formé des courants d'air peuvent qui peuvent entrer en collision au centre de la pièce. Les courants d'air peuvent créer deux tourbillons d'air à déplacement lent, ce qui donne à l'utilisateur la sensation d'être environné par de l'air frais. Les trous dans le déflecteur autorisent une petite quantité d'air à travers ceux-ci, ce qui aide à empêcher une condensation de se former dans le côté arrière du déflecteur quand le climatiseur fonctionne sous des conditions d'humidité élevée.
