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 où 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, étant donné qu'un programme anti-air froid du climatiseur a un impact sur un courant de ventilateur d'une unité intérieure, le climatiseur effectue une détermination erronée, de sorte que celui-ci exécute fréquemment un autonettoyage. Par conséquent, la présente invention concerne un procédé de commande d'un climatiseur et un climatiseur. Le climatiseur comprend une unité intérieure. Le procédé de commande consiste à : lorsqu'un climatiseur effectue une fonction de chauffage, acquérir une valeur de courant de ventilateur d'une unité intérieure lorsqu'une température de tuyau de bobine de l'unité intérieure est à une température prédéfinie ; et effectuer de manière sélective une invite, en fonction de la valeur de courant de ventilateur, selon laquelle le climatiseur doit être nettoyé. Au moyen de la présente invention, il est possible de déterminer avec précision qu'un climatiseur doit être nettoyé, de sorte à inviter un utilisateur de manière opportune à nettoyer le climatiseur, afin d'empêcher les situations dans lesquelles le climatiseur est sale et bloqué et une détermination erronée se produit, ce qui permet d'améliorer l'expérience de l'utilisateur.
