Abstract
(EN)
The purpose of the present invention is to realize a water purification device capable of reducing consumption of an adsorption removal member and suppressing deterioration in the function. Provided is a water purification device (1) that purifies water by using an RO membrane (18) and a DI filter (19). In a water passage from the RO membrane (18) to the DI filter (19), an opening/closing mechanism (32) for blocking a water flow in the water passage is provided.

L'objet de la présente invention est de réaliser un dispositif de purification de l'eau capable de réduire la consommation d'un élément d'élimination d'adsorption et de supprimer la détérioration de la fonction. L'invention concerne un dispositif de purification de l'eau (1) qui purifie l'eau à l'aide d'une membrane RO (18) et d'un filtre DI (19). Il est prévu, dans un passage d'eau de la membrane RO (18) au filtre DI (19), un mécanisme d'ouverture/fermeture (32) pour bloquer un écoulement d'eau dans le passage d'eau.
