Abstract

La présente invention se rapporte au domaine technique des climatiseurs et vise à résoudre les problèmes selon lesquels, lorsqu'un climatiseur existant est nettoyé au moyen d'un nettoyage manuel, un utilisateur ne peut pas déterminer avec précision le moment auquel le climatiseur doit être nettoyé, de sorte que le climatiseur ne peut pas être nettoyé de manière opportune, et lorsque le climatiseur est nettoyé au moyen d'un autonettoyage, le climatiseur effectue facilement une détermination erronée, de sorte que celui-ci exécute fréquemment un auto-nettoyage. L'invention concerne ainsi un dispositif de commande d'un climatiseur et un climatiseur. Le climatiseur comprend une unité intérieure. Le procédé de commande consiste à : acquérir une valeur de température ambiante ; acquérir une valeur de courant prédéfinie correspondante en fonction de la valeur de température ambiante ; adopter la valeur de courant prédéfinie en tant que valeur de courant standard ; acquérir une valeur de courant de ventilateur d'une unité intérieure ; et notifier sélectivement, en fonction de la valeur de courant de ventilateur et de la valeur de courant standard, la nécessité de nettoyer un climatiseur. Au moyen de la présente invention, la nécessité de nettoyer un climatiseur peut être déterminée avec précision, de façon à inviter un utilisateur de manière opportune à nettoyer le climatiseur, de sorte à empêcher les situations où le climatiseur est sale et bloqué et une détermination erronée se produit, ce qui permet d'améliorer l'expérience de l'utilisateur.
