Abstract

L'invention concerne un procédé de commande pour une machine à laver à tambour conçue non seulement pour économiser de l'énergie et de l'eau, mais aussi pour améliorer l'efficacité du lavage. Ce procédé consiste: à détecter une quantité de linge introduite dans le tambour; à prédéterminer un niveau d'eau en fonction de la quantité de linge détectée; à acheminer une quantité d'eau de lavage inférieure au niveau d'eau prédéterminé, mais suffisante pour mouiller le linge et pour entraîner un pompage-circulation; à effectuer un premier lavage pour laver le linge grossièrement par circulation de la petite quantité d'eau de lavage; à réacheminer de l'eau de lavage jusqu'au niveau d'eau prédéterminé; et à effectuer un deuxième lavage du linge par rotation du tambour sans pompage-circulation.
