Abstract: The present invention discloses an apparatus for producing ozone by electrolysis of water. The apparatus comprises a pair of frames facing each other, and an anode and a cathode oppositely arranged between the two pieces of frames. Between the anode and the cathode is provided a solid polymer electrolyte membrane for transferring hydrogen ions formed during electrolysis. In addition, an auxiliary electrode is provided between the cathode and the solid polymer electrolyte membrane such that a scale can be formed on the surface of the auxiliary electrode. A spacer 60 is inserted between the anode and the cathode. Tap water as well as pure water and cation-exchanged water can be used as a raw material water to produce high-concentration ozone water. A uniformity of pressure between the electrodes and the solid polymer electrolyte membrane can be achieved, thereby providing for a stable operation.

Abstract: A radical generating system integrates a bubble generating means, an ozone generating means, and a radical changing means. In the radical generating system, the bubble generating means generate air for generating air bubbles and pumping. The ozone generating means applies high voltage to the air bubbles and ozone introduced from the bubble generating means in order to produce ozone. The radical changing means changes the ozone which is introduced from the ozone generating means into a first active oxygen radical. The housing has the bubble generating means, the ozone generating means, and the radical changing means all formed integrally. The radical generating system sterilizes bacilli such as bacteria, viruses, mold, fungi, or algae which live in the water or air. The radical generating system also improves washing effect of a washing machine by oxidizing and bleaching actions of radicals.
