Abstract

L'invention concerne un procédé de nettoyage des peluches pour un lave-linge/sèche-linge intégré. Le procédé comporte les étapes d'un processus de purge des peluches et d'un processus d'évacuation des peluches comme suit: au cours du processus de purge des peluches: pendant l'amenée d'eau au cours du processus de lavage, de l'eau condensée chasse les peluches jusqu'au bas d'un échangeur (1) de chaleur; et au cours du processus d'évacuation des peluches: de l'eau est amenée à un tambour intérieur jusqu'à ce que le niveau d'eau atteigne un premier niveau d'eau prédéfini (H2), un processus d'agitation est effectué dans le tambour intérieur, l'écoulement de l'eau agitée chassant les peluches et les évacuant, le premier niveau d'eau prédéfini (H2) étant plus haut qu'une sortie d'eau au bas de l'échangeur (1) de chaleur; et le processus d'agitation accélérant la rotation du tambour intérieur jusqu'à une première vitesse de rotation prédéfinie, la première vitesse de rotation prédéfinie étant supérieure à la vitesse de rotation au cours d'un programme normal de lavage ou de rinçage d'un lave-linge. Le procédé de nettoyage des peluches selon l'invention est simple, efficace et facile à réaliser. Le procédé peut non seulement chasser les peluches jusqu'au bas de l'échangeur (1) de chaleur, mais peut également évacuer les peluches à temps, réduisant ainsi la quantité de peluches s'accumulant dans un conduit du système de séchage et prolongeant la période de stabilité des performances de séchage du lave-linge/sèche-linge intégré.
