Abstract

La présente invention concerne un lave-linge, comprenant : un corps de boîte, une cuve de lavage servant à contenir de l'eau, et une plaque de montage montée sous la cuve de lavage et utilisée pour supporter la cuve de lavage. La plaque de montage est reliée au corps de boîte au moyen d'un composant d'amortissement des vibrations ; la cuve de lavage est disposée rotative sur la plaque de montage ; un canal d'évacuation d'eau servant à guider l'eau du haut vers le bas est disposé au niveau du côté externe de la cuve de lavage ; l'extrémité supérieure du canal d'évacuation d'eau est en communication avec l'intérieur de la cuve de lavage, et l'extrémité inférieure du canal d'évacuation d'eau s'étend vers le bas le long de la paroi de la cuve de lavage jusqu'au fond de la cuve de lavage, pour évacuer l'eau dans la cuve de lavage ; la paroi interne du côté du canal d'évacuation d'eau en regard de la cuve de lavage s'éloigne progressivement de l'axe de la cuve de lavage du haut vers le bas, et l'angle de déviation par rapport à l'axe de la cuve de lavage est de 0° à 10°. En fonction du lave-linge, une structure de cuve externe est retirée, et par conséquent, la capacité du lave-linge est étendue. D'autre part, dans la présente invention, un canal d'évacuation d'eau est disposé au niveau du côté externe de la cuve de lavage, empêchant ainsi l'eau de lavage d'être concentrée au niveau de l'extrémité supérieure de la cuve de lavage. Un faible bruit est produit pendant le fonctionnement, et la durée de vie est longue.
