Abstract

A water purifier removes harmful materials from tap water by electrochemical oxidation-reduction and distillation without using any filters. The water purifier has an electrochemical oxidation-reduction unit which removes heavy metals and organic materials from tap water by an electrochemical oxidation-reduction reaction, thus providing pre-purified water. A distillation unit heats the pre-purified water in order to vaporize the water while distilling off harmful materials. The vapor is discharged from the distillation unit and is condensed by a condenser while flowing in a vapor guide pipe, thus providing finally-purified water.
