Abstract

L'invention concerne une machine à laver, étant susceptible d'éliminer le déséquilibre produit par le linge dans un état de réalisation continue d'une opération de déshydratation normale, sans permettre à la rotation d'un tambour rotatif de décélérer ou de s'arrêter pendant un processus d'opération de déshydratation de la machine à laver, de déshydrater efficacement le linge dans un mode ne produisant pas de vibration ni de bruit et d'empêcher l'augmentation de la consommation d'énergie. La machine à laver comporte : un cylindre de lavage (5) ; une pluralité d'équilibreurs (6) creux, disposés sur la surface circonférentielle interne du cylindre de lavage (5) le long de la direction axiale du cylindre de lavage (5) ; des unités annulaires de réception d'eau (18, 69), formées dans un état de multiples couches chevauchantes de rigoles de guidage d'eau (19a, 19b, 19c) annulaires correspondant séparément aux équilibreurs (6) et fixées au niveau des parties d'extrémité dans la direction axiale de la surface externe du cylindre de lavage (5) ; des parties de passage d'eau (24a, 24b, 24c), reliées à une partie des rigoles de guidage d'eau (19a, 19b, 19c) et des équilibreurs (6) correspondant aux rigoles de guidage d'eau (19a, 19b, 19c) ; et des buses de pulvérisation (25a, 25b, 25c), conçues pour injecter indépendamment de l'eau d'ajustement dans les rigoles de guidage d'eau (19a, 19b, 19c).
