2. Description of the Related Art Conventionally, it has been important to deodorize and sterilize cutting boards, kitchen knives and refrigerators for storing food in restaurants and food factories from the viewpoint of food hygiene. It is already known among those skilled in the art to use an ozone generator configured to generate ozone by using electric discharge for the purpose.

[0003] However, ozone produced by the above-mentioned apparatus can have a great effect on deodorization and sterilization in food processing tools and refrigerators due to its characteristics. Not only promotes the deterioration of foods touched or stored in the refrigerator,
There is a disadvantage that the health of workers who perform food processing while staying in the atmosphere of high-concentration ozone or workers who enter and leave the refrigerator is easily affected.

On the other hand, in the field of electronic equipment or the polymer industry, the static electricity eliminator that removes static electricity generated in the process with the automation and speeding up of the production system and the transport system is the rotary ozone generator described above. Utilizing the same principle as above, a high voltage is applied between a pair of electrodes to generate negative ionized air, which is sprayed on a charged object to electrically neutralize the charging of the object. However, it has recently been found that by releasing this negative ionized air together with low-concentration ozone, the same deodorizing and sterilizing effects as high-concentration ozone are recognized.

[0005]
