Abstract

L'invention concerne une structure support d'amortissement de vibrations pour machine à laver à tambour inclinée, qui comporte une plaque de base de machine à laver, un amortisseur incliné vertical, et un montage de fixation pour le dispositif de lavage dont l'axe est incliné. L'amortisseur incliné vertical est supporté entre ledit montage de fixation et la plaque de base. Ladite structure support d'amortissement de vibrations se compose de trois montages d'amortissement de vibrations. Deux amortisseurs avant sont verticaux inclinés, dont les extrémités inférieures sont fixées à la plaque de base, et les extrémités supérieures sont placées sur chaque côté de la partie avant dudit montage de fixation, respectivement. Le troisième amortisseur de vibrations comme montage arrière est placé au milieu du dos du montage de fixation. L'extrémité supérieure du montage arrière est reliée à la fixation, et l'extrémité arrière à la plaque de base. D'une part, la structure support à trois points est utilisée dans la structure support d'amortissement de vibrations et, d'autre part, la structure support à trois points peut supporter une certaine amplitude d'oscillation et présente une excellente résistance aux vibrations.
