Patent ID: 7591931

Claim:
A water sterilizing apparatus comprising; a container provided with an electrolytic cell composed of two substantially separate chambers with limited communications therebetween; inflow pipes and outflow pipes connected with the container; the container comprises external container coupled with at least one inflow pipe and an internal container in which a plurality of through-holes penetrating to the electrolytic cell are formed on side surface of the internal container and are coupled with at least one outflow pipe: a voltage feeding unit that is connected with a conductor composed of a conductive member provided in each chamber of the electrolytic cell and that feeds the conductor with DC voltage; and a plurality of metal ion eluting bodies that are respectively contained in each chamber of the electrolytic cell and that elute metal ions by continued mutual frictional movements among the metal ion eluting bodies due to an agitating action of a stream of water and by electrolysis caused between positive poles resulting from their contact with a conductor connected with a positive side of the voltage feeding unit in a chamber and negative poles resulting from their contact with a conductor connected with a negative side of the voltage feeding unit in another chamber.
