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