【産業上の利用分野】本発明は、無声放電法によりオゾ
ンを発生して被殺菌体である空気や水の雑菌を殺菌した
り消臭するオゾン発生装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozone generator for generating ozone by a silent discharge method to sterilize and deodorize various bacteria such as air and water which are the objects to be sterilized.
【０００２】[0002]
【従来の技術】一般にオゾンは、殺菌効果と消臭効果を
有することが知られている。このような効果を利用し

放電ランプに交流電圧を印加してオゾンを発生させてい
る。2. Description of the Related Art Generally, ozone is known to have a bactericidal effect and a deodorizing effect. Utilizing such an effect, for example, in Japanese Examined Patent Publication No. 63-51025, an AC voltage is applied to a low pressure mercury discharge lamp to generate ozone.
【０００３】上述の無声放電法は、一対の平面電極間に
ガラス板あるいはマイカ、セラミックス等の誘電体をは
さみ、酸素含有気体（例えば空気）を上記電極間に平行
して流しながら６〜１８ＫＶの交流高電圧を印加し対電
極に垂直に放電する方法である。In the silent discharge method described above, a glass plate or a dielectric material such as mica or ceramics is sandwiched between a pair of flat electrodes, and an oxygen-containing gas (for example, air) is flown in parallel between the electrodes to generate a voltage of 6 to 18 KV. This is a method in which an AC high voltage is applied and discharge is performed perpendicularly to the counter electrode.

してオゾンを生成するものである。放電空隙間では、こ
のオゾン生成反応と並行してオゾンの分解反応も行われ
るが、これは酸素原子同士の衝突によるもので放電によ
るオゾン生成にとって逆効果となる。The electrons emitted from the electrode collide with oxygen molecules to dissociate oxygen into atoms or generate excited oxygen molecules. Oxygen molecules and excited oxygen molecules react with other oxygen molecules to generate ozone. In the discharge gap, ozone decomposition reaction is also performed in parallel with this ozone generation reaction, but this is due to collision of oxygen atoms with each other, which has an adverse effect on ozone generation by discharge.
【０００５】しかしながら、この放電法の場合は、オゾ
ン生成のための電力消費量が小さく、安定な性能が得ら
れ、且つ、簡易な操作性であること等の理由から使用さ
れている。However, this discharge method is used because of low power consumption for ozone generation, stable performance, and simple operability.
【０００６】ところが、無声放電法による一対の平面電
極間におけるオゾン生成量は、平面電極がある面積以上
になるといくら面積を大きくしても増加しないという現
象がある。However, there is a phenomenon that the amount of ozone generated between a pair of flat electrodes by the silent discharge method does not increase even if the flat electrodes have a certain area or more.
【０００７】この現象は、一対の平面電極の一方に石英

も近い部分で放電を行うため、この放電部分以外の領域
は全く不必要な部分となる。In this phenomenon, a dielectric made of quartz glass or ceramic is adhered to one of the pair of flat electrodes, and a high voltage is applied between the pair of flat electrodes via the dielectric. Since the discharge is performed at the portion closest to the discharge space distance depending on the surface shape of the above, the area other than this discharge portion is completely unnecessary.

生成量が減少する欠点があった。Particularly, as described above, when the object to be sterilized (for example, air) is sterilized by the ozone generated between the pair of flat electrodes sandwiching the dielectric, the reason for the constitution is as follows. Since it is not possible to secure the air circulation portion, it is necessary to form the air circulation portion by using a guide member which is a separate component, and the mounting thereof is troublesome. In addition, since the dielectric and the guide member are interposed between the flat electrodes, the amount of ozone produced is reduced.
【０００９】さらに、前述のように平面電極の面積を大
きくしてもオゾン生成量が増加しないことから、連続し
て多くのオゾン生成を行うことができなかった。Further, as described above, even if the area of the flat electrode is increased, the ozone generation amount does not increase, so that it is not possible to continuously generate a large amount of ozone.

ても十分にその効果を奏する。The projecting portion of the dielectric of the present invention is formed by forming the dielectric into a polygonal shape. However, the dielectric may be formed into a cylindrical shape and projecting like a blade around the outer periphery thereof,
The rod-shaped electrodes may be arranged so as to approach each other inward by means of springs or the like, and when the dielectric is arranged in the discharge space, the side walls of the dielectric may be brought into close contact with the rod-shaped electrodes by the springs. Further, the sterilized object is sufficiently effective not only in air (oxygen-containing gas) but also in water (oxygen-containing liquid).

し、分解に伴うオゾンの減少を防止する。As described above, according to the present invention, since the cylindrical dielectric is arranged in the discharge space of the electrode unit,
The dielectric can be used as a guide member for the substance to be sterilized and has a function of emitting electrons to generate original ozone, and the structure is simple and the dielectric can be simply installed in the discharge space. The body can be placed between the rod-shaped electrodes, and work such as alignment is unnecessary. In particular, the tubular dielectric increases the ozone generation area, increases the amount of ozone generated, and prevents the decrease of ozone due to decomposition.

It is also carried out through the protrusions between the rod-shaped electrodes, and ozone can be efficiently generated.
