かっている。[Prior art] As an ozonizer electrode, a high AC voltage is applied between the electrodes with a dielectric material in between to cause a discharge between the electrodes, and this discharge energy is used to synthesize ozone from the raw material oxygen. things are the mainstream. In order to increase ozone generation efficiency, it is important to make the electrode shape, distance between electrodes, dielectric thickness, applied voltage value and frequency appropriate, etc.; It is also known that controlling the temperature is an important factor. In particular, when the temperature of the raw material gas is high, it is difficult for discharge to occur, and in the case of raw material gas or air, it is known that NO is generated or combined with water vapor to generate nitric acid, which accelerates the deterioration of the elements surrounding the electrode part. There is.
このため、原料ガスの除湿は効率と耐久性の面で不可欠

高い。[Problem to be Solved by the Invention 1] As mentioned above, it is generally preferable to dehumidify the raw material gas supplied to the ozone generator. Because air is used as raw material, when the refrigerator door is opened and outside air enters, the humidity immediately reaches 100% and condensation is unavoidable. When condensation occurs on the discharge electrode of an ozone generator, normal discharge cannot be obtained until the condensation disappears, and almost no ozone is generated. Furthermore, since a high voltage is applied, there is a concern that troubles such as abnormal leakage may occur. Current commercially available products prevent problems by not discharging to generate ozone when the door is open. It is highly likely that the condensation will not disappear and conditions that are unfavorable for ozone generation will continue.

ことが好ましい。The surface heater of the present invention may be of any type as long as it has a predetermined amount of heat to achieve the purpose of the present invention, but the heating element such as nichrome wire or aluminum foil may be insulated with a suitable insulation material such as an insulating resin. It is preferable to use a material that is embedded in or coated with a material, and it is particularly preferable to use a material that is coated with silicone resin or fluororesin because it is resistant to ozone.
また誘導電極と面ヒーターの接合に於てもなるべく密着
性よく熱を伝えることができかつ耐熱性、耐オゾン性の
強いシリコーン系又はフッ素系樹脂接着材が好ましい。Also, for joining the induction electrode and the surface heater, it is preferable to use a silicone-based or fluorine-based resin adhesive that can conduct heat with as good adhesion as possible and has strong heat resistance and ozone resistance.
