<p>PURPOSE:To reduce the amount of production of toxic ozone emitting strong stimulant odor by forming one of the high voltage impressing electrodes from a metal wire while forming the other from an electroconductive ceramic plate. CONSTITUTION:One of the high voltage impressing electrodes is formed from a metal wire while the other formed from an electroconductive ceramic plate. An extremely thin wire of diameter 50mum made of tungsten is installed as a cathode 7 in a position which is parallel with an anode 3 and 0.5mm apart from the inner surface mating with the exterior surface where the anode 3 faces the outer side face 2. An electric circuit member 9 to control high voltage load is installed on the bottom surface 8 of an outer box 1 which is located 10mm apart approximately from the cathode 7. A hole 10 for suction of the outside air is bored in the residual area of accommodation box bottom surface 8 where the electric circuit member 9 is secured, and a suction motor fan 11 is installed. This fan 11 decreases the atmospheric ozone discharged from an ionic air discharge port 12.</p> |
