Abstract

La présente invention concerne une machine à laver qui est équipée : de plaques latérales gauche et droite (8) qui configurent les surfaces latérales de la carrosserie (1) et qui sont formées de tôles d'acier ; d'un couvercle avant (5) qui configure la surface avant de la carrosserie (1) et dans lequel une porte (4) qui peut être fermée est disposée ; d'un couvercle supérieur (2) qui configure la surface supérieure de la carrosserie (1) ; d'un réservoir d'eau (12) qui est disposé à l'intérieur de la carrosserie (1) pour pivoter librement ; et d'un tambour rotatif (11) supporté de façon pivotante à l'intérieur du réservoir d'eau (12). De multiples rainures (9) sont formées sur les plaques latérales gauche et droite (8). Les rainures (9) présentent la forme d'arcs ayant une courbure plus élevée lorsque les rainures se rapprochent de la surface avant de la carrosserie (1), qui est le côté qui comprend la porte (4), ce qui augmente la rigidité des plaques latérales (8) dans les directions de haut en bas et de gauche à droite et réduit les vibrations durant l'essorage.
