[55] Then, the heater 500 is employed for soaking the laundry when re-circulating washing water to help dirt separated from the laundry, as well as for heating washing water for sterilizing the laundry. [56] Since water in a down surface of the tub 120 is re-circulated by the circulating pump 400 and the water is sprayed into the rotating drum 130, not only the laundry may be dampened equally but also washing water may be saved. [57] Preferably, a filter (not shown) is provided at the circulating pump 400 or the circulating channel pipe 410 for filtering dirt of the circulating washing water.

  • a controller controls the dispenser 200 to draw the smaller amount of the washing water into the tub 120. Thereby, a process of initially supplying washing water may start.
  • the smaller amount of the washing water means that some of the smaller washing water is enough to dampen the laundry and the rest of the washing water is enough to prevent cavitation in a process of pumping washing water.
  • cavitation air would be included in a process of pumping circulation only to cause noise as well as to deteriorate pumping efficiency.

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.
