Abstract

La présente invention a trait à un dispositif de lavage. Le dispositif de lavage comprend : un boîtier ; une cuve qui est supportée par le boîtier, la cuve étant dotée d'une ouverture d'introduction du linge permettant d'introduire ou de sortir du linge dans une partie avant de celle-ci, et d'un trou d'amenée d'air extérieur permettant d'introduire de l'air extérieur pour qu'il passe au travers ; un tube d'amenée d'air extérieur qui passe par le boîtier et qui est relié au trou d'amenée d'air extérieur de manière à guider l'air extérieur en dehors du boîtier dans le trou d'amenée d'air extérieur ; un tambour qui est doté d'une ouverture d'introduction du linge correspondant à l'ouverture d'introduction du linge de la cuve, le tambour étant installé rotatif à l'intérieur de la cuve ; un arbre qui est relié à une partie arrière du tambour ; un logement de roulement qui supporte de façon rotative l'arbre ; et un ensemble suspension permettant de réduire la vibration du tambour et d'une partie d'entraînement qui comprend un moteur permettant de faire tourner l'arbre. De la sorte, le dispositif de lavage peut être structuré de manière à offrir une capacité de lavage accrue, et l'environnement sous pression à l'intérieur de la cuve peut être amélioré de manière à empêcher que le tambour ne se déplace vers l'avant.
