Abstract

La présente invention concerne un procédé de commande de nettoyage d'ensemble filtre d'un système de filtration d'eau de circulation d'une machine à laver, consistant à : conformément à une séquence prédéfinie, déterminer si un ensemble filtre nécessite un nettoyage; et si l'ensemble filtre nécessite un nettoyage, émettre un signal visuel et/ou sonore pour inviter un utilisateur à exécuter une séquence de nettoyage d'ensemble filtre. La présente invention permet de déterminer si un ensemble filtre nécessite un nettoyage conformément à une séquence prédéfinie et, après avoir déterminé que le nettoyage est nécessaire, d'inviter intelligemment l'utilisateur à effectuer un nettoyage d'ensemble de membranes. La présente invention permet d'éviter un nettoyage excessif ou insuffisant de l'ensemble de membranes de filtre de la machine à laver provoqué par une négligence de l'utilisateur, et permet à la fois de garantir le flux de filtration de l'ensemble filtre et d'empêcher, autant que possible, un gaspillage d'eau et d'électricité provoqué par un nettoyage trop fréquent de l'ensemble de membranes de filtre de la machine à laver. En outre, le procédé de commande selon la présente invention permet de nettoyer et d'entretenir très efficacement l'ensemble filtre de la machine à laver, restaurant fondamentalement sa performance à l'état initial, prolongeant la durée de vie de l'ensemble filtre.
