JP2001244045A - Negative ion generator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To resolve the problem in the conventional method that the efficiency in generation and emission of negative ions is not satisfactory because ions generated on opposing metal electrodes obtained by impressing a dc voltage to the metal electrodes, and that such unwanted problems as the generation of zone is observed. SOLUTION: Ions attached and accumulated on the electrodes are released from the constraints of an electric field by setting the potential applied to the electrodes momentarily to zero or slightly negative. Free negative ions of the air alone are collected by flowing air or the like. Moreover, in order to extract negative ions from the free-ions, a sub-electrode is provided to adsorb positive ions, and only the negative ions are sent out efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications] The relationship between negative ions and the body has been studied for a long time in Europe and the United States, but in recent years the effects of negative ions have been elucidated by the development of natural sciences and medicine. Attempts have been made to use it for processing and for environmental improvement.

[0002] Therefore, there is a demand for a device that efficiently generates and releases a large amount of negative ions.

[0003]

2. Description of the Related Art A direct current voltage is applied to an opposite metal electrode, and ions generated between the metal electrodes are used.

[0004]

In the prior art, high efficiency was not expected for generation and release of negative ions, and unnecessary problems such as generation of ozone were found.

[0005]

In order to efficiently generate negative ions, a convex portion is provided on the electrode plate, or one of the electrodes is formed into a needle shape to concentrate electric charges so that the potential gradient is as large as possible. Although an ion current is generated, corona discharge occurs at the same time, and O3 (ozone) is generated.

In order to prevent this, it is necessary to quickly extract the generated negative ions, so that a fresh negative ion shower is obtained by forcibly exhausting the air with a fan.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The number of ions to be released due to the deposition of + ions on the positive electrode and the-ions on the negative electrode to electrodes to which a high voltage is applied is limited. Therefore, the potential applied to the electrode is instantaneously reduced to zero or slightly negative to facilitate ion release, and the ions attached to the electrode are released from the restraint of the electric field and released-only air ions are collected by blowing or the like. Is what you do.

Further, in order to extract negative ions from free ions, a sub-electrode is provided to adsorb positive ions and efficiently transmit only negative ions.

[0009]

According to the present invention, since it has the above functions and effects, it can be built into a fluorescent lighting device to provide a static eliminator for preventing positive charging.
It is an industrially useful invention that is a negative ion generator that can be charged and adsorbed to fine particles in the air and creates a refreshing space by the negative ion effect as an air purifier that removes dirt from the air.
