Abstract

L'invention concerne une machine à laver comprenant une cuve extérieure (9) équipée d'un couvercle extérieur (9a) muni d'un composant (50) de passage d'eau. Ledit composant (50) de passage d'eau est configuré de telle façon que de l'eau du robinet soit fournie en provenance d'une unité d'alimentation en eau. Dans le composant (50) de passage d'eau sont formées des ouvertures (50b1) de surfaces latérales pour projection d'eau, qui projettent de l'eau indirectement sur le bord extérieur d'un anneau (8c) d'équilibrage d'une cuve (8) de lavage et d'essorage, ainsi que des ouvertures (50a1) de surface inférieure pour projection d'eau, qui projettent de l'eau sur les surfaces latérales supérieures de l'anneau (8c) d'équilibrage. L'eau du robinet projetée sur le bord extérieur de l'anneau (8c) d'équilibrage est lancée sur la surface intérieure (9s) de la cuve extérieure (9) par force centrifuge pendant la rotation de la cuve (8) de lavage et d'essorage. L'eau du robinet frappant la surface intérieure (9s) s'écoule le long de la surface intérieure (9s) sous l'effet de la gravité.
