Abstract

Unité intérieure d'un climatiseur comprenant : une coque de machine, dotée d'une entrée d'air utilisée pour permettre à un flux d'air de s'écouler vers l'intérieur, une sortie d'air située sur le côté avant du fond de la coque de machine afin de permettre au flux d'air de s'écouler vers l'extérieur, et un orifice de brise douce situé dans la partie inférieure du côté avant de la coque de machine pour permettre au flux d'air de s'écouler vers l'extérieur, un conduit de sortie d'air étant formé sur la coque de machine et situé sur le côté interne de la sortie d'air ; un déflecteur d'air externe, agencé en rotation au niveau de la sortie d'air de manière à régler de manière commandée l'ouverture et la fermeture et la direction de sortie d'air de la sortie d'air ; et un déflecteur d'air interne, agencé en rotation dans le conduit de sortie d'air de manière à distribuer de manière régulée le flux d'air dans le conduit de sortie d'air vers l'orifice de brise douce et/ou la sortie d'air et à régler la direction d'écoulement du flux d'air vers la sortie d'air. Le déflecteur d'air interne et le déflecteur d'air externe peuvent présenter une pluralité de combinaisons d'états de position. Une pluralité de modes d'alimentation en air de l'unité intérieure du climatiseur tels qu'un refroidissement classique, un chauffage classique, une augmentation d'air froid, un confort sans vent et un soufflage vertical vers le bas peuvent être obtenus au moyen de la coopération du déflecteur d'air interne et du déflecteur d'air externe, des exigences d'alimentation en air diversifiées d'un utilisateur sont satisfaites et l'expérience d'utilisation de l'utilisateur est améliorée.
