Abstract

La présente invention concerne une machine à laver capable d'économiser du détergent. La machine à laver entièrement automatique comprend : une cuve de lavage/essorage disposée dans un corps pour laver le linge ; une boîte à détergent destinée à stocker un détergent ; une unité d'alimentation en eau utilisée pour distribuer le détergent dans la boîte à détergent dans la cuve de lavage/essorage ; un dispositif de décontamination par ultrasons pour permettre à des ondes ultrasonores générées par un générateur d'ultrasons d'agir sur le linge immergé dans l'eau dans un réservoir d'eau pour décontaminer le linge ; une partie d'écoulement utilisée pour évacuer l'eau contenant le détergent du réservoir d'eau vers la cuve de lavage/essorage ; une partie de détection d'opération (803) destinée à délivrer en sortie un signal de réutilisation indiquant que le détergent utilisé dans une opération de décontamination effectuée par le dispositif de décontamination par ultrasons a été réutilisé dans une opération de lavage ; et une partie de commande (801) destinée à commander une opération d'injection de détergent effectuée par une partie de mécanisme d'injection, la partie de commande (801) réduisant, sur la base de la délivrance en sortie du signal de réutilisation, la quantité de détergent à injecter dans la cuve de lavage/essorage.
