Abstract

L'invention concerne un procédé de commande de machine à laver, et une machine à laver. Le procédé de commande de machine à laver comprend : un processus d'essorage commandant, au niveau d'une partie finale du processus d'essorage, un dispositif d'évacuation d'eau pour fermer, effectuer un premier processus d'alimentation en eau, et laisser dans une machine à laver l'eau alimentée pour un processus de rinçage; et le processus de rinçage ouvrant une vanne d'alimentation en eau, commandant l'alimentation en eau pour le remplissage jusqu'à un niveau d'eau défini, et démarrant le rinçage. Le procédé est utilisé pour alimenter de l'eau pendant le processus d'essorage, et étant donné qu'une cuve interne tourne pendant l'alimentation en eau, l'eau alimentée peut laver une paroi de la cuve et retirer la crasse des vêtements, améliorant ainsi un effet de lavage. De plus, l'alimentation en eau à la fin du processus d'essorage et l'arrêt à l'avance du dispositif de charge d'eau permettent d'assurer que l'eau alimentée n'est pas gaspillée et est utilisée dans le processus de rinçage ultérieur, économisant l'eau utilisée pour la lessive.
