Abstract

La présente invention concerne un tambour intérieur étanche comprenant une paroi latérale (11) et un fond (12) solidaires. La paroi latérale (11) et le fond (12) sont agencés de manière étanche. Une rainure d'évacuation d'eau (13) est formée sur le dessus de la paroi latérale (11), et le flux d'eau dans le tambour intérieur (1) et l'eau de lessive sont évacués du tambour intérieur (1) via la rainure d'évacuation d'eau (13). L'invention a également pour objet un lave-linge comprenant le tambour intérieur étanche, et un procédé de lavage destiné audit lave-linge. En comparaison avec l'état de la technique, l'absence de trous dans le tambour intérieur empêche la pénétration d'eau dans la zone située entre le tambour intérieur et la tambour extérieur, et permet ainsi une sensible économie d'eau de lavage. Dans le même temps, la saleté et les bactéries que se trouvent dans cette zone ne viennent pas en contact, par l'intermédiaire de l'eau, avec les vêtements dans le tambour intérieur, ce qui permet d'éviter efficacement l'infection croisée par des bactéries. Le lave-linge s'avère ainsi hygiénique, écologique et fiable lors de son utilisation.
