  • the invention relates to a dishwasher with a system for softening or decarbonating the water used in the dishwasher for rinsing operations, i. E. to reduce the lime content of the rinsing fluid. More particularly, the invention relates to a dishwasher with a raw water supply, at least one bobbin for receiving items to be cleaned and with a device for water softening and / or water desalination of the raw water from the water network, which comprises at least one lonenSbehalter and a fillable Regenenerffenbehalter.

Abstract

L'invention concerne un lave-vaisselle capable, compte tenu de considérations économiques, de détartrer ou de décarbonater l'eau utilisée pour le rinçage dans ce lave-vaisselle. Le dispositif de rinçage selon l'invention est, à cet effet, caractérisé en ce qu'il est prévu une amenée d'eau brute (2), au moins un récipient de rinçage et un dispositif de traitement de l'eau brute en vue du détartrage et/ou de l'élimination des sels (décarbonatation) de l'eau brute en provenance du réseau de conduites d'eau, comprenant un récipient échangeur d'ions (9) renfermant au moins un échangeur d'ions, ainsi qu'un récipient remplissable d'agent régénérateur (6), l'eau brute étant amenée au récipient de rinçage via le récipient échangeur d'ions (9), et en ce qu'il est prévu un dispositif de séparation d'eau (5) dirigeant l'eau brute provenant de l'amenée (2), alternativement vers le récipient échangeur d'ions (9) ou vers le récipient d'agent régénérateur (6). Le lave-vaisselle selon l'invention est avantageux en ce sens que la quantité d'eau requise pour la production de la saumure régénérante ne doit pas être mesurée ou retenue dans un récipient séparé de réserve d'eau de régénération, de sorte qu'il n'est plus nécessaire d'avoir un tel récipient, réduisant ainsi les frais de production ainsi que l'encombrement du dispositif de traitement d'eau brute selon l'invention.
