ある。(Means for Solving the Problems) In order to achieve the above object, the present invention provides an optical ozone generator including a plurality of ion lamps and a blower in a case, in which at least one of the plurality of ion lamps is In addition to keeping the lights on at all times to ensure a certain amount of ozone generation, the ozone concentration is detected by an ozone sensor installed in a space with little convection, and based on this detected ozone concentration, other ion lamps are controlled to turn on and off to generate ozone. It controls the concentration.
（実施例）
つぎに、本発明の一実施例を図面にしたがって説明する
。(Example) Next, an example of the present invention will be described with reference to the drawings.
本発明における光学式オゾン発生装置は、ケース内に複
数本（実施例では２本）のイオン灯１ａ。The optical ozone generator according to the present invention includes a plurality of (two in the embodiment) ion lamps 1a in a case.

イオン灯を消灯し、以下となればリレー５をＯＮシて点
灯することにより、第２図に示すように、たとえば、貯
蔵庫内をほぼ所定のオゾン濃度に保持するものである。Further, the ozone sensor 3 detects the change in electrical resistance value that occurs when ozone gas is adsorbed on the surface of the oxide semiconductor and extracts it as an ozone concentration signal.In other words, it directly detects the ozone concentration and sends it to the control unit 4. If the input signal value exceeds a predetermined range, the relay 5 is turned ON to turn off the one ion lamp, and if it is below, the relay 5 is turned ON to turn it on, as shown in FIG. For example, the ozone concentration inside the storage is maintained at approximately a predetermined level.
ところで、オゾンは化学的に不安定なものであり、分解

すく、還元性物質が共存すると、この活性酸素は還元性
物質を急速に酸化する。By the way, ozone is chemically unstable and easily decomposes and separates into oxygen and highly reactive active oxygen (0), and when reducing substances coexist, this active oxygen Oxidizes rapidly.
したがって、対流の存在する雰囲気中ではオゾンの挙動
がｍ雑であり、貯蔵庫内のオゾン濃度を正確に測定する
ことができない。Therefore, the behavior of ozone is rough in an atmosphere where convection exists, making it impossible to accurately measure the ozone concentration inside the storage.
一方、雰囲気中の空気が静止状態であれば、オゾンの広
がりは、拡散のみであって、オゾンｉｔＪ度を正確に測
定し得る。On the other hand, if the air in the atmosphere is still, ozone spreads only by diffusion, and the degree of ozone itJ can be measured accurately.
したがって、本発明においては、前記オゾンセンサーは
対流の少ない箇所、たとえば、滅菌しようとする物品間
あるいは、オゾン発生装置が小型の場合には、オゾン発
生装置のケース内に設置するようにしである。Therefore, in the present invention, the ozone sensor is installed in a place where there is little convection, for example, between articles to be sterilized or, if the ozone generator is small, inside the case of the ozone generator.
前記構成からなるため、？Ｉｒ＜ＥをＯＮすると、まず
、２本のイオン灯１ａ、ｌｂが点灯し、発生したオゾン
は送風機２により貯蔵室内に送り込まれる。Because it consists of the above configuration? When Ir<E is turned on, first, the two ion lamps 1a and lb are turned on, and the generated ozone is sent into the storage chamber by the blower 2.
そして、滅菌物品間あるいは、オゾン発生装置のケース
内に設けたオゾンセンサー３により、オゾン濃度が所定
値に達したことを検出すると、直ちに、リレー５を駆動
して前記一方のイオン灯ｔｂを消灯する。When the ozone sensor 3 installed between the sterilized articles or inside the case of the ozone generator detects that the ozone concentration has reached a predetermined value, the relay 5 is immediately driven to turn off the one ion lamp tb. do.
その後、一定時間経過して、イオン濃度が所定値より低
下すると、前記一方のイオン灯１ｂが点灯する。Thereafter, when the ion concentration falls below a predetermined value after a certain period of time has elapsed, the one ion lamp 1b is turned on.
つまり、常時、１本のイオン灯１ａは点灯してベースオ
ゾン量を確保し、他のイオン灯１ｂのＯＮ−ＯＦＦ制御
によりオゾン濃度を一定に保持すことになる。That is, one ion lamp 1a is always lit to ensure the base ozone amount, and the ozone concentration is kept constant by ON/OFF control of the other ion lamp 1b.
なお、オゾン指示計６を制御部４から独立させることに

経済的である。In this way, since at least one ion lamp is always on and other ion lamps are turned on and off to control the concentration, it is easy to control the ozone concentration.
The ion lamp has a long lifespan and is economical because the number of times it is turned on and off is small.
