Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ozone generator configured to generate ozone using corona discharge by applying a high voltage, and in particular, can efficiently discharge ozone and ionized air while reducing the size of the apparatus body. The present invention relates to a rotatable ozone generator.
[0002]
[Prior art]
Conventionally, cutting boards, kitchen knives or refrigerators for food storage in restaurants and food factories have been important to deodorize and sterilize from the viewpoint of food hygiene, and use corona discharge by applying high voltage. It is already known by those skilled in the art to use an ozone generator adapted to generate ozone for its use.
[0003]
However, the ozone produced by the above device can have a great effect on deodorization and sterilization in food processing tools and refrigerators due to its characteristics, but when the ozone concentration was increased unnecessarily, it touched the food processing tools. Not only does it promote the alteration of food and food stored in the refrigerator, but also has the disadvantage that it tends to adversely affect the health of workers who process food in and out of the refrigerator while staying in an atmosphere of high-concentration ozone. It was a thing.
[0004]
On the other hand, in the field of electronic equipment or polymer industry, as the production system and transport system are automated and speeded up, the static eliminator that removes static electricity generated in the process is the same as the rotary ozone generator described above. In principle, negatively ionized air is generated by applying a high voltage between a pair of electrodes using the principle, and this is sprayed on the charged object to electrically neutralize the charge of the object. Thus, it has been found that by releasing this negative ionized air together with low-concentration ozone, a deodorizing and sterilizing effect equivalent to that of high-concentration ozone is recognized.
[0005]
[Problems to be solved by the present invention]
The present invention was devised in the course of research and development aimed at improving the capability of a rotary ozone generator while eliminating the adverse health effects of workers in an ozone atmosphere in view of the above circumstances. The purpose of the device is to make the device body compact, but it can efficiently generate ozone and ionized air, and has a deodorizing and sterilizing effect without adversely affecting the human body. It is intended to provide a rotary ozone generator that can be enhanced.
[0006]
[Means for Solving the Problems]
In order to solve the problem, the first technical means adopted by the present invention is that a rotor constituting a rotating electrode is loosely fitted coaxially with a predetermined gap in a cylindrical fixed electrode, and the both electrodes A first mechanism that generates ozone by applying a high voltage between the first and a fixed electrode in the vicinity of the rotating outer periphery of a sirocco fan that forms a rotating electrode, and a second mechanism that generates ionized air by applying a high voltage between the two electrodes. The mechanism is configured to release ozone generated by the first mechanism and ionized air generated by the second mechanism to the outside of the apparatus through the rotating sirocco fan. As a second technical means, ozone generated by the first mechanism is sucked from an intake port that supplies air to the second mechanism, and is released outside the apparatus together with ionized air generated by the second mechanism. And a third technical hand As said in the first rotor constituting the mechanism, it is characterized in that the suction vanes to assist the air supply to the cylinder-shaped fixed electrode in are juxtaposed.
