Abstract:
1. A unit for producing sterilized water by underwater discharge of supply water, comprising: an electrode module including a pair of electrode plates, each of which has a plurality of elongated slots formed therein, and a hollow electrode separator positioned between the electrode plates to separate the electrode plates from each other; a pair of electrode rods for applying different voltages to the respective electrode plates; and a frame positioned at one side of the electrode module and having portions for receiving the respective electrode rods, wherein each of the electrode plates has a pair of holes formed at a circumference thereof, through which the respective electrode rods penetrate, the pair of holes having different diameters, the diameter of one of the pair of holes being substantially the same as the outer diameter of the pair of electrode rods, the diameter of the other hole being larger than the outer diameter of the pair of electrode rods, and the electrode plates are stacked in such a manner that the each of the pair of holes of one of the electrode plates overlaps a respective one of the pair of holes of another electrode plate having a different diameter so that different voltages are applied to the electrode plates through the respective electrode rods, and wherein each of the electrode rods is a screw having an externally threaded portion and each of the electrode plates is fastened to the externally threaded portion of one of the pair of electrode rods so that each of the electrode plates is in contact with one of the pair of electrode rods along the circumferential surface of the hole through which the respective electrode rod penetrates, wherein the electrode separator has a pair of recessed portions in communication with the holes through which the respective electrode rods penetrate and a connection portion for connecting the recessed portions to each other.
