Abstract

L'invention concerne un appareil d'entraînement de lave-linge comprenant : un arbre externe relié à une cuve de lavage ; un arbre interne disposé de manière rotative à l'intérieur de l'arbre externe et relié à un pulsateur ; un rotor externe relié à l'arbre interne ; et un stator disposé entre un rotor interne et le rotor externe avec un écartement entre eux, caractérisé en ce que : la surface circonférentielle externe de l'arbre externe possède un premier palier et un second palier disposé dessus ; le premier palier et le second palier sont montés dans un premier logement de palier et un second logement de palier fixé à une cuve externe ; et une partie de couplage pour fixer le stator au premier logement de palier est formée en une seule pièce sur une bobine. L'appareil d'entraînement de lave-linge selon la présente invention peut éliminer l'embrayage classique et peut ainsi réduire le coût de fabrication, simplifier le procédé de fabrication, et réduire la hauteur d'un lave-linge.
