Abstract

La présente invention se rapporte au domaine technique des climatiseurs, concerne, en particulier, un procédé de commande de climatiseur et un climatiseur, et vise à résoudre les problèmes liés à l'utilisation peu pratique de stores roulants et à une mauvaise expérience d'utilisateur de climatiseurs existants. À cette fin, un dispositif de protection contre l'air du climatiseur selon la présente invention comprend un élément de support, un élément d'entraînement, une bobine, et un store roulant monté sur la bobine, l'élément de support étant raccordé à un logement d'une unité intérieure, la bobine est raccordée de manière rotative à l'élément de support, l'extrémité de sortie de l'élément d'entraînement est en raccordement d'entraînement avec la bobine, et le store roulant peut bloquer l'air évacué par une sortie d'air. Le procédé de commande selon la présente invention comprend les étapes consistant à : déterminer s'il existe une personne dans une zone prédéfinie pendant le fonctionnement du climatiseur ; et en fonction du résultat de la détermination, étendre sélectivement le store roulant pour empêcher l'air évacué par la sortie d'air d'être soufflé vers la zone prédéfinie. Au moyen d'un tel réglage, le climatiseur selon la présente invention peut commander automatiquement l'état du store roulant, ne nécessite pas une opération manuelle d'un utilisateur, et est intelligent, ce qui améliore considérablement l'expérience de l'utilisateur.
