Abstract

La présente invention concerne un lave-linge pouvant ajouter automatiquement un détergent en utilisant une pression négative et un procédé de lavage de linge associé. Le lave-linge comprend un orifice d'arrivée d'eau, au moins un récipient de détergent et une cuve de lavage. Au moins deux canaux d'arrivée d'eau sont situés entre l'orifice d'arrivée d'eau et la cuve de lavage. Chaque canal d'arrivée d'eau comprend un ensemble mécanisme d'extraction qui utilise une pression négative pour extraire un détergent dans le récipient de détergent et qui est en communication avec au moins un autre ensemble mécanisme d'extraction d'un autre canal d'arrivée d'eau de façon à prélever de l'eau et à diluer et guider le détergent extrait depuis le mécanisme d'extraction jusqu'à la cuve de lavage. La présente invention utilise la pression négative provoquée par le flux d'eau pour ajouter automatiquement une quantité raisonnable de détergent sans modifier l'effet de lavage. De plus, la présente invention a une structure simple. Elle accroît donc l'efficacité de lavage du linge.
