<p><P>PROBLEM TO BE SOLVED: To provide a method of releasing negative ion into an appropriate number of compartments of a building by generating high negative voltage of not less than 7,000 V with the pulse of not less than 50 kilo pulse by a negative high voltage generating device, and releasing negative ion with high density from a negative ion generating device arranged to the appropriate number of the compartments of the building. <P>SOLUTION: The negative ion generating device comprises the negative high voltage generating device capable of outputting negative high voltage direct current pulse of not less than 7,000 V with the pulse of not less than 50 kilo pulse; a distributor for distributing the negative high voltage direct current pulse to the negative ion generating device arranged to the appropriate number of compartments of the building through a lead cable; a blast pipe arranged to an appropriate side surface made of insulation material opened downward of which, total shape is formed into rectangular, pyramidal, or conical shape; a ventilation hole made of insulation material arranged to a ventilation port of the blast pipe, covering whole part thereof; and the negative ion releasing device of which an opening part has an antistatic edge part. <P>COPYRIGHT: (C)2004,JPO</p> |
