<p>PROBLEM TO BE SOLVED: To provide an ion generating device which can easily regulate the generation amount of an ion. SOLUTION: For an ion generating device wherein a high voltage generating circuit 26 and a blowing fan are provided in a box body, and a radiation electrode 17 for ion generation is provided on a blowing path or in the vicinity of the blowing path, the high voltage generating circuit 26 makes the radiation electrode 17 generate a pulse wave, and at the same time, the cycle of the pulse wave is made changeable by a signal from a control part. By this method, comparatively easily a negative ion only is utilized, and the generation of ozone which is harmful to human body is suppressed, and at the same time, the generation amount of the ion can be easily adjusted.</p> |
