Abstract

PROBLEM TO BE SOLVED: To provide a device for adjusting the amount of ozone generated and for removing dust, by detachably providing a needle electrode with its end situated outside of, and having a fixed distance left by, one opening part of a counter electrode and substantially on a center axis of the opening part, and the counter electrode with its inner circumferential surface acting as an electrode and confronting the needle electrode. SOLUTION: When a direct-current high voltage is applied between a tubular electrode 1 and a needle electrode 2, corona discharge takes place on the Coulomb's law. By this discharge energy, a wind including ions and ozone is generated. This wind flows outward from an opening part 1b of the tubular electrode 1 and diffuses ions and ozone generated in the tubular electrode 1. By generating and diffusing ions and ozone in this way and utilizing their germ- removing and deodorizing action, smells and the like in a room or in a car are removed. The amount of ions and ozone generated and their wind velocity can be adjusted by adjusting the distance between the discharge electrodes, the diameter and length of the tubular electrode 1, the magnitude of the voltage, etc.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozone generator utilizing discharge airflow generated by applying a voltage to a discharge electrode comprising a cylindrical electrode and a combination of a cylindrical electrode and a needle electrode. .

[0002]

2. Description of the Related Art A conventional ozone generator generates ozone mainly by a combination of a ceramic electrode and a tungsten wire electrode, and discharges ozone using an electric fan.

[0003]

In the conventional ozone generator, it was essential to use an electric fan to flow and diffuse ozone. For this reason, it has been necessary to take measures against the increase in the number of parts and noise generated by the motor.

[0004] Further, since the structure of the ceramic electrode is complicated, there is another problem that the manufacturing cost such as the cost for the mold is high.

Further, in order to increase or decrease the amount of generated ozone, it is necessary to increase or decrease the size of the ceramic electrode and lengthen or shorten the length of the tungsten electrode wire.
It was almost impossible to adjust the amount of ozone after assembly.

In addition, if used for a long time, dust adheres to the electrodes and the amount of ozone generated decreases, so it is necessary to remove the dust. There was a problem that no countermeasures were taken.

An object of the present invention is to provide an ozone generator which can adjust the amount of generated ozone and remove dust without using a blower such as an electric fan and at low cost.

[0008]

The object of the present invention is to provide a needle whose tip is located on a substantially central axis of the opening with a fixed interval outside one of the openings of the counter electrode. And a counter electrode having an inner peripheral surface facing the needle electrode as an electrode. As another solution, a high DC voltage is applied between a discharge electrode composed of a cylindrical electrode and a needle electrode arranged near one opening of the cylindrical electrode, thereby forming the cylindrical electrode. What discharges ions and ozone air from the other opening, provides a cartridge detachably attached to a case containing a discharge electrode and a high-pressure generator, and arranges a cylindrical electrode in the cartridge. is there.

Another solution is to provide a cylindrical electrode having conductivity, a tip arranged at a fixed interval outside one of the openings of the cylindrical electrode, and a substantially central portion of the cylindrical electrode. A needle electrode having conductivity that is positioned, and a high-voltage generator that applies a high DC voltage between the cylindrical electrode and the needle electrode, comprising the cylindrical electrode and the needle electrode; There is an ion and ozone generator that generates ions and ozone when applied and generates a wind containing the ions and ozone flowing outward from the other opening of the cylindrical electrode.

In the ozone generator of the present invention, a high voltage is applied to a discharge electrode consisting of a cylindrical electrode and a needle electrode, and when the inside of the cylindrical electrode is charged, the cylindrical electrode is formed by Coulomb force and corona discharge action. An air current containing ions and ozone is generated in the electrode. The ions and ozone air are used as they are to flow out of the opening of the cylindrical electrode to generate and diffuse negative ions and ozone.

Particularly, the tip of the needle electrode in the present invention is positioned outside one opening of the cylindrical electrode and substantially at the center thereof. By positioning the tip of the needle-shaped electrode in this way, it is possible to generate a more effective wind for causing ions or ions and ozone to flow out and diffuse.

Further, since it is very important in the present invention to keep the distance between the cylindrical electrode and the tip of the needle electrode constant, the electrode mounting member is used to keep this distance constant. I keep it.
