Abstract

La présente invention concerne une machine à laver de type à tambour comprenant : une cuve (42) supportée élastiquement dans un corps d'habillage de machine à laver (41) ; un tambour rotatif (43) disposé rotatif dans la cuve (42) ; une vanne d'alimentation en eau (57) qui est un dispositif d'alimentation en eau servant à alimenter en eau la cuve (42) ; un moteur qui entraîne en rotation le tambour rotatif (43) ; et un trajet de vidange (55) qui évacue l'eau de la cuve (42). En outre, la machine à laver de type à tambour comprend : une pompe de vidange (63) disposée au milieu du trajet de vidange (55) et aspirant et évacuant l'eau ; un filtre disposé dans le trajet de vidange (55) et capturant des corps étrangers ; et un dispositif de commande qui commande successivement chaque processus tel que le lavage, le rinçage et l'essorage. Le dispositif de commande pilote par intermittence la pompe de vidange (63) lors de l'opération de vidange effectuée par la pompe de vidange (63). Ainsi, une masse telle qu'une peluche qui est capturée par le filtre est pulvérisée par le flux d'eau généré par le fonctionnement intermittent de la pompe de vidange (63) et est évacuée par l'intermédiaire du trajet de vidange (55).
