本考案はオゾン発生器を利用した脱臭装置に関
するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a deodorizing device using an ozone generator.

In general, when food is stored in a refrigerator, etc., various odors are emitted from the food, which may make you feel disgusted when you open the refrigerator door, or the odors of other foods may transfer to the stored food, causing the flavor of the food to change. There were some drawbacks.
そこで、従来は活性炭を庫内に置き、その吸着
特性を利用して庫内の臭気を除去するものであつ
たが、此の種のものは初期の脱臭効果は優れてい
るものの、その後急速に低下し、やがて活性炭の
吸着量が飽和に達した時にその効果は無くなる。 Conventionally, activated carbon was placed inside the refrigerator and its adsorption properties were used to remove odors from inside the refrigerator.However, although this type of carbon has an excellent initial deodorizing effect, it rapidly deteriorates after that. When the adsorption amount of activated carbon reaches saturation, the effect disappears.
又、上記活性炭は飽和吸着量に達しているか否
かを判定するのが難しく、定期的に活性炭を交換
しなければならなかつた。 Furthermore, it is difficult to determine whether the activated carbon has reached a saturated adsorption amount, and the activated carbon must be replaced periodically.
そこで、昨今、小型、軽量で且つ安定した脱臭
効果を得るためにオゾン発生器を内蔵した脱臭装
置が考えられてきている。 Therefore, in recent years, deodorizing devices that are small, lightweight, and have a built-in ozone generator have been considered in order to obtain a stable deodorizing effect.

However, since the ozone generator used in conventional deodorizing equipment generates a silent discharge between a high-voltage electrode and a low-voltage electrode in the air, the discharge gap is large and stable discharge cannot be performed. First, it is necessary to apply a high voltage, which has various drawbacks such as the overall size and weight of the device.

The present invention involves embedding a ground electrode in a base material made of alumina ceramic, forming a hollow body with this base material, and arranging a plurality of strips at appropriate intervals in the longitudinal direction of at least one surface of the base material. A discharge electrode is disposed, and an ozone generator is provided that generates ozone by causing creeping discharge between the discharge electrode and the surface of the base material.

According to the present invention, since ozone is generated by causing creeping discharge between the discharge electrode and the surface of the base material, the discharge gap is determined by the thickness of the ceramic, and therefore the discharge gap can be easily reduced. The discharge voltage can also be reduced, and stable performance can be obtained. Further, since the ozone generator is a hollow body and creeping discharge occurs on its surface (inner and outer surfaces), a large discharge area can be obtained and a large amount of ozone can be generated.

The case has the shape of a rectangular parallelepiped, and an air supply hole 2 and an exhaust hole 3 are formed on both end faces, and inside the case, an ozone generator 4, an ozone decomposition filter 5, and an ozone decomposition filter 5 are installed from the air supply hole 2 side.

are installed in order.

ゾンを発生させるようにしている。 As shown in FIGS. 3 and 4, the ozone generator 4 has a hollow body (for example, a cylindrical body, etc.) formed of a base material 7 made of alumina ceramic, and a plate-shaped ground electrode 8 is installed in the base material 7. At the same time, a plurality of discharge electrodes 9 (made of tungsten) are spirally arranged at appropriate intervals in the longitudinal direction of at least one surface of the base material 7 (in this example, the inner surface of the hollow body). A creeping discharge is caused between the discharge electrode 9 and the inner surface of the base material 7 to generate a large amount of ozone.

し、該悪臭成分を分解する。 That is, when a voltage is applied between the earth electrode 8 and the discharge electrode 9, a creeping discharge occurs between the discharge electrode 9 and the surface of the base material 7 as shown in FIG. 5, and at this time ozone is generated. It reacts with malodorous components (mainly methyl sulfide) in the air sucked in through the air supply hole 2, and decomposes the malodorous components.

量も多くなる。 According to the above embodiment, the base material 7 of the ozone generator 4 is formed into a hollow shape, and a plurality of discharge electrodes 9 are arranged in the longitudinal direction on the inner surface of this hollow body, so that the ozone generator 4 has a flat plate shape. The efficiency of ozone generation is higher than that of the discharge electrode 9, and by forming the discharge electrode 9 in a spiral shape, the edge of the creeping discharge becomes longer, and the amount of ozone generated increases accordingly.
又、上記オゾン発生器４には図示しないが発露
止用のヒーターが設けられている。 Although not shown, the ozone generator 4 is provided with a heater for preventing dew generation.
１０は高電圧発生装置にして、上記オゾン発生
器４に高電圧を印加するようになつている。 Reference numeral 10 denotes a high voltage generator, which applies a high voltage to the ozone generator 4.

の印加電圧で良いものである。 However, according to the ozone generator 4 of the present invention, creeping discharge occurs between the discharge electrode 9 and the surface of the base material 7 as described above, so the discharge gap can be changed simply by appropriately setting the thickness of the base material 7. Therefore, the discharge gap can be easily reduced compared to conventional ozone generators that discharge in the air, and therefore, even at high voltages, the applied voltage is about 1/3 of that of conventional ozone generators. It's a good thing.

When a high voltage is applied to the ozone generator 4 through the ozone generator 4, ozone is generated from the ozone generator 4 by creeping discharge as described above, while air containing malodorous components is sucked from the air supply hole 2. The malodorous components in the air react with the ozone and are decomposed. When the gas after the reaction between ozone and malodorous components passes through the ozone decomposition filter 5, residual ozone is decomposed and removed, and the gas is discharged to the outside through the exhaust hole 3.

Since the present invention is constructed as described above, the discharge gap can be easily reduced by simply setting the thickness of the ceramic appropriately, and therefore stable operation is achieved without requiring a large discharge voltage. In addition, by making the ozone generator hollow, the discharge area can be increased.
Therefore, the amount of ozone generated increases and a remarkable effect can be achieved in that stable and effective deodorization can be performed.
