OZONIZER

摘要

PURPOSE: An ozonizer is provided which maximizes ozone generation amount per unit area, easily cools an ozone generating part and an electrode, and keeps ozone generation amount as it is even in a long period of use. CONSTITUTION: The ozonizer comprises: (i) a cylindrical A electrode(10) which has a hollow(11) having certain inner diameter; (ii) a cylindrical insulator(20) which is combined with the hollow of the A electrode and has a hollow(21) having certain inner diameter; (iii) a cylindrical B electrode which is combined with the hollow of the insulator and has a hollow on the inside, a spiral groove(32) having a certain depth and many communication holes(33) on the outer circumference side to connect the spiral groove and the hollow; (iv) an insulating tube(40) which is combined with the outer circumference of the B electrode; (v) a high voltage generator(50) which impresses direct high voltage on the A electrode and the B electrode; (vi) an air inflow guide member(60) and an air discharge guide member(70) which are respectively fixed on both ends part of the insulator; and (vii) a ventilating means(80) which supplies air through the air inflow guide member.
