Abstract

Sont divulgués un procédé de commande de l'essorage d'une machine à laver et une machine à laver. Le procédé de commande consiste : pendant un programme d''essorage exécuté par une machine à laver, à acquérir une valeur de vibration et/ou une valeur de bruit d'un tambour de lavage à la vitesse de rotation actuelle; à comparer la valeur de vibration et/ou la valeur de bruit avec un seuil de vibration prédéfini et/ou un seuil de bruit prédéfini, qui correspondent à la vitesse de rotation actuelle du tambour de lavage; et, en fonction d'un résultat de comparaison, à commander la vitesse de rotation du tambour de lavage. Selon le procédé de commande de l'essorage d'une machine à laver décrite dans la présente invention, lors d'une augmentation de la vitesse de rotation et par comparaison avec un seuil de vibration et/ou un seuil de bruit à la vitesse de rotation, il est déterminé si la vitesse de rotation peut encore être augmentée, et un procédé pour répondre au cas où une valeur de vibration et/ou une valeur de bruit dépassent le seuil de vibration et/ou le seuil de bruit à la vitesse de rotation. Dans l'invention, au moyen de la détection d'un seuil de vibration réel et/ou d'un seuil de bruit réel, la vitesse de rotation du tambour de lavage pendant l'essorage est contrôlée, de telle sorte qu'un enchevêtrement de vêtements est réduit avec précision, et le problème d'une vibration élevée et/ou d'un bruit élevé provoqués par une grande quantité d'excentricité est également évité dans la plus grande mesure.
