Abstract

L'invention concerne une structure de sortie d'air, une machine à montage mural et un climatiseur. La structure de sortie d'air comprend une paroi de guidage d'écoulement (100) et une sortie d'air (200). Un côté de la paroi de guidage d'écoulement (100), proche de la sortie d'air (200), comprend une section inclinée (101) et une section horizontale (102) s'étendant dans la direction horizontale à partir de la section inclinée (101). Par conséquent, l'aire de la sortie d'air ne diminue pas pendant le refroidissement, assurant ainsi une capacité de refroidissement rapide, et l'air est alimenté horizontalement à travers la sortie d'air (200) afin d'éviter le soufflage d'air sur une personne, l'air étant alimenté à la manière d'une douche pendant le refroidissement par le climatiseur, améliorant ainsi le confort.
