L'invention concerne une machine à laver entièrement automatique, ayant : un trajet d'eau de circulation (25), disposé sur une surface latérale d'un tambour de lavage et de déshydratation (21) et permettant à l'eau fournie par rotation d'un pulsateur (23) de passer à travers celui-ci; un élément de formation de trajet d'eau (26) fait de résine, formant le trajet d'eau de circulation (25) avec une paroi circonférentielle interne (21a) du tambour de lavage et de déshydratation (21); une partie de montage de filtre (201) formée dans l'élément de formation de trajet d'eau (26); et une unité de filtre (27), montée de façon rotative dans la partie de montage de filtre (201), aspirant l'eau revenant du trajet d'eau de circulation (25) vers le tambour de lavage et de déshydratation (21) et l'eau s'écoulant le long de la paroi circonférentielle interne (21a) dans un flux généré par rotation du pulsateur (23) et permettant à l'eau de passer à travers cette dernière, et collectant des peluches contenues dans l'eau passant à travers cette dernière. La partie de montage de filtre (201) comprend un arbre de support inférieur (202) constituant un arbre de rotation de l'unité de filtre (27) et une partie d'ouverture (206) formée à l'arrière de l'arbre de support inférieur (202) et en communication avec le trajet d'eau de circulation (25). Une partie de paroi (210) pour supprimer la sortie d'eau provenant de la partie d'ouverture (203) est formée vers la paroi circonférentielle interne et sur une surface de l'élément de formation de trajet d'eau (26) faisant face au trajet d'eau de circulation (25). La partie de paroi (210) peut améliorer l'efficacité de collecte de peluches de l'unité de filtre (27).
