Abstract

L'invention porte sur un climatiseur, dans lequel, lorsque l'angle de définition de direction du vent d'un écran est changé, même si des moyens de détection de corps humain détectent par erreur un corps humain du fait d'un changement de la quantité de lumière infrarouge provoqué par le déplacement d'une partie de l'écran à l'intérieur d'un champ visuel de détection dans lequel est reçue une lumière infrarouge, l'information détectée durant le déplacement de l'écran n'est temporairement pas utilisée pour déterminer l'état d'un humain (la présence, la position, la quantité d'activité, etc., d'un humain) dans des moyens de détection d'état de corps humain, de telle sorte que l'information détectée d'une substance autre qu'un corps humain, qui est générée lorsque l'angle de l'écran est changé, peut être empêchée d'être déterminée par erreur comme étant l'information détectée d'un corps humain.
