Abstract

La présente invention concerne le domaine technique des climatiseurs, et vise à résoudre le problème selon lequel des climatiseurs ne peuvent pas être nettoyés à temps du fait que les climatiseurs existants nécessitent un nettoyage manuel et les utilisateurs ne peuvent pas déterminer avec précision le moment auquel les climatiseurs ont besoin d'être nettoyés ainsi que le problème lié à l'exécution fréquente d'un autonettoyage par les climatiseurs en raison de défauts d'évaluation facilement provoqués par le mode d'autonettoyage des climatiseurs. Le procédé de commande consiste à : obtenir une pluralité de valeurs de courant de ventilateur à l'intérieur d'une période de temps prédéfinie après la mise sous tension d'une unité intérieure ; adopter la valeur de courant de ventilateur qui apparaît le plus fréquemment parmi la pluralité de valeurs de courant de ventilateur en tant que valeur de courant standard ; obtenir une valeur de courant en temps réel de l'unité intérieure ; et réaliser de manière sélective une invite, en fonction de la valeur de courant en temps réel et de la valeur de courant standard, selon laquelle un climatiseur doit être nettoyé. La présente invention peut déterminer avec précision si un climatiseur doit être nettoyé, ce qui permet à un utilisateur de nettoyer le climatiseur, d'éviter un blocage par la saleté et des défauts d'évaluation du climatiseur, et d'améliorer l'expérience de l'utilisateur.
