Abstract

La présente invention concerne un procédé de commande de machine à laver et une machine à laver sans nettoyage, la machine à laver comprenant un tambour interne non poreux (1), le tambour interne non poreux (1) étant doté d'une ouverture d'évacuation d'eau (4), et une soupape d'étanchéité étant positionnée au niveau de l'ouverture d'évacuation d'eau (4) ; lorsque la machine à laver exécute une évacuation ou un drainage d'eau, le procédé consiste à commander au tambour interne non poreux (1) de tourner à une vitesse de rotation réglée correspondante de telle sorte que la force centrifuge de la rotation du tambour interne amène la soupape d'étanchéité à ouvrir l'ouverture d'évacuation d'eau (4) pour évacuer ainsi l'eau du tambour interne non poreux (1). Le procédé de commande de machine à laver, en coopération avec la structure de soupape d'étanchéité de la machine à laver, met en œuvre le drainage de l'eau de lavage et de l'eau de rinçage au moyen de la vitesse de rotation, et ne nécessite donc pas l'agencement d'une structure de drainage d'eau principale ni de logique de commande de machine à laver complexe. Le drainage de l'eau peut également être mis en œuvre à une vitesse de rotation relativement faible, ce qui réduit les vibrations et le bruit de la machine à laver. De plus, les caractéristiques de distribution uniforme de l'eau dans les vêtements sont utilisées pour obtenir une distribution uniforme avant l'évacuation ou le drainage de l'eau, rendant la rotation du tambour interne plus stable avec moins de vibrations et de bruit.
