  • Patent number: 8540860
    Abstract: Disclosed is a unit for producing sterilized water. The unit comprises an electrode module, a pair of electrode rods and a frame. The electrode module includes a pair of electrode plates and a hollow electrode separator positioned between the electrode plates to separate the electrode plates from each other. Each of the electrode plates has a plurality of elongated slots formed therein. The electrode rods apply different voltages to the respective electrode plates. The frame is positioned at one side of the electrode module and has portions for receiving the respective electrode rods. Each of the electrode plates has a pair of holes formed at the circumference thereof. The electrode rods penetrate through the respective holes. The holes have different sizes. The electrode plates are stacked in such a manner that the holes having different sizes overlap each other. This stack enables the application of different voltages to the electrode plates through the respective electrode rods.
