ELECTRIC DEIONIZED WATER PRODUCING DEVICE

摘要

The present invention provides an electric deionized water producing device comprising: a desalting chamber (4) defined by at least two ion-exchange membranes (1, 2) and filled with an ion exchanger; a first concentration chamber (5a) positioned adjacent to one side of the desalting chamber with one of the ion-exchange membranes therebetween; a second concentration chamber (5b) positioned adjacent to the other side of the desalting chamber with another of the ion-exchange membranes therebetween; and a pair of electrode chambers (6a, 6b) with one electrode chamber being disposed at the outer side of the first concentration chamber (5a) and the other electrode chamber being disposed at the outer side of the second concentration chamber (5b), wherein the electric deionized water producing device is provided with: a main body part (20) formed by comprising the desalting chamber (4), the concentration chambers (5a, 5b), and the electrode chambers (6a, 6b); a pair of fixing plates (9a, 9b) disposed in such a way that the main body part (20) is positioned therebetween; and an elastic body (7). The elastic body (7) is disposed in such a way that the fixing plates (9a, 9b) and the elastic part (7) apply compressive stress to the main body part (20) in the arrangement direction of the desalting chamber (4), the concentration chambers (5a, 5b), and the electrode chambers (6a, 6b).
