Title:
DC IONIZER
Document Type and Number:
WIPO Patent Application WO/2007/052589
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a DC ionizer capable of maintaining a constant amount of ions
produced for a long period of time. [MEANS FOR SOLVING PROBLEMS] A DC ionizer which
blows ionized air containing positive and negative ions toward an object to be
neutralized by means of a fan. The DC ionizer comprises an ion balance sensor (14)
for detecting the ion balance of the positive and negative ions, an amount-of-ions sensor
(15) for detecting the amount of negative ions, and control means for controlling the
negative voltage applied to a negative electrode (12N) according to the output signal
from the amount-of-ions sensor (15) to control the amount of negative ions so
as to be approximately constant and controlling the voltage applied to a positive
electrode (12P) according to the output signal from the ion balance sensor (14)
to control the ion balance of the positive and negative ions so as to keep the balance.
