せることができるため、効率よく利用できる。Example 10. Next, a tenth embodiment of the present invention will be described. Since the high-voltage generator 23a outputs a high voltage at a relatively high frequency, the surroundings of the first electrode 23b enter into a plasma state and electrons proceed toward the second electrode 23c, but the probability that the electrons are absorbed by the second electrode 23c. Becomes smaller and becomes more likely to exist as negative ions between the first and second electrodes. As shown in FIG. 22, the first electrode 2 is provided between a and a ′.
Negative ions are generated at the tip of 3b. When a high voltage is output at a high frequency, the polarity of the electrode changes instantaneously, so the probability of being absorbed by the second electrode 23c only during aa 'decreases. In addition, the influence of frequency on the generation of ions will be described with reference to a graph based on one experimental data shown in FIG. In the figure, d is the first electrode 23b and the second electrode 23.
The distance between c, N is the number of the first electrodes 23b, Vo-p is the firing voltage, and A is the air volume of the blower 25. As shown in FIG. 23, it was found that a large number of ions were generated when the frequency was about 40 Hz to 60 Hz, and when the frequency was too low or too high, the number of ions generated was small and the frequency was relatively high. It turns out that is good. It should be noted that this optimum relatively high frequency is the above d, N, V
It depends on the conditions such as op and A. Also,
For example, when the operation of the high pressure generator 23a is stopped, the blower 2
No. 5 operates the blower 25 longer than the high-pressure generator 23a, such as delaying the stop slightly, so that the negative ions generated between the first and second electrodes can be sufficiently circulated to the outside of the ion generator, so that they can be used efficiently. it can.
