Abstract

La présente invention concerne le domaine technique des appareils ménagers et concerne spécifiquement un procédé de commande pour un climatiseur, ainsi qu'un climatiseur, visant à résoudre le problème selon lequel des appareils de protection contre l'air de climatiseurs existants n'ont qu'une seule fonction et ont un faible rapport qualité-prix. Pour ce qui précède, le climatiseur de la présente invention comprend une unité intérieure et un appareil de protection contre l'air, l'appareil de protection contre l'air permettant de bloquer l'air évacué par une sortie d'air. Le procédé de commande de la présente invention comprend les étapes suivantes : lorsque le climatiseur est dans le processus d'exécution d'un mode d'auto-nettoyage, permettre à l'appareil de protection contre l'air de bloquer la sortie d'air. Au moyen de l'agencement mentionné ci-dessus, en plus de pouvoir empêcher l'air évacué de la sortie d'air de souffler directement vers un utilisateur, l'appareil de protection conte l'air de la présente invention peut également bloquer la sortie d'air pendant que le climatiseur est dans le processus d'exécution du mode d'auto-nettoyage, de façon à empêcher la poussière évacuée de la sortie d'air de souffler vers l'utilisateur, ce qui permet d'améliorer le rapport qualité-prix de l'appareil de protection contre l'air.
