Abstract

Le lave-linge de l'invention comprend : un caisson de lave-linge présentant une trappe de chargement/rerait de lessive par le haut ; un bac de réception de l'eau qui est supporté de manière élastique dans le caisson du lave-linge ; un bac rotatif logé dans le bac récepteur d'eau, faisant office de bac de lavage et d'essorage centrifuge ; et un dispositif d'alimentation en eau comprenant une valve d'alimentation reliée à une source d'amenée d'eau et un carter d'eau destiné à recevoir et à stocker l'eau provenant de la soupape d'alimentation, ledit dispositif d'alimentation en eau étant disposé dans la partie haute du caisson de lave-linge et envoyant l'eau dans le bac rotatif. Le carter d'alimentation en eau comprend une partie réceptrice recevant l'eau en provenance de la soupape d'alimentation et une partie de stockage de l'eau. Parmi les surfaces des parois qui forment la partie de stockage, la paroi de surface latérale qui fait face par en haut à l'intérieur de bac rotatif comporte un trou d'injection pour l'alimentation du bac rotatif en eau stockée dans la partie de stockage.
