Abstract

Dispositif de distribution automatique d'additif et procédé de commande de machine à laver, le dispositif de distribution automatique comprenant : au moins deux boîtes de stockage de liquide (10) qui sont respectivement utilisées pour stocker des additifs ; et au moins deux circuits d'alimentation en eau (1), les deux circuits d'alimentation en eau (1) étant reliés à une boîte de stockage de liquide respective (10) de manière correspondante, les deux circuits d'alimentation en eau (1) étant tous deux pourvus d'une structure d'aspiration à pression négative (2) qui génère une pression négative au niveau d'une buse d'aspiration (15) de la structure d'aspiration à pression négative (2) en utilisant respectivement le flux d'eau d'un circuit d'alimentation en eau correspondant (1). Les buses d'aspiration (15) des deux structures d'aspiration à pression négative (2) sont en communication l'une avec l'autre au moyen d'un circuit d'eau de liaison (11), et n'importe laquelle des structures d'aspiration à pression négative (2) est utilisée pour extraire un additif dans la boîte de stockage de liquide (10) reliée à l'autre circuit d'alimentation en eau (1).
