〔技術分野〕
本考案は食品貯蔵庫等に用いられる冷蔵庫脱臭
装置に関するものである。[Detailed Description of the Invention] [Technical Field] The present invention relates to a refrigerator deodorizing device used in food storages and the like.
一般に、冷蔵庫に食品を貯蔵すると、その食品
から種々の臭気が発生し冷蔵庫の扉を開けた際に
嫌悪感をおぼえたり、貯蔵食品に他の食品の臭気
が転移し食品の風味を損なつたりする欠点が有つ
た。
In general, when food is stored in the refrigerator, 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, impairing the flavor of the food. There was a drawback.
そこで、従来は高圧電極と低圧電極との間に高
電圧を印加してオゾンを発生させ、該オゾンによ
つて悪臭成分を除去する脱臭装置を、冷蔵庫内に
設置することにより上記欠点を解消していた。 Conventionally, the above-mentioned drawbacks have been solved by installing a deodorizing device inside the refrigerator, which generates ozone by applying a high voltage between a high-voltage electrode and a low-voltage electrode, and uses the ozone to remove malodorous components. was.
然し、上記脱臭装置のオゾン生成量は放電時の
電流密度に関係があり、この電流密度が低下する
とオゾンの生成量も低下する傾向にある。又上記
電流密度は放電時の雰囲気温度及び雰囲気湿度が
高くなればなる程低下するもので、放電雰囲気温
度及び湿度が低温且つ低湿度となる程オゾンの生
成量が多い。 However, the amount of ozone produced by the deodorizing device is related to the current density during discharge, and as this current density decreases, the amount of ozone produced also tends to decrease. The current density decreases as the ambient temperature and humidity during discharge become higher, and the lower the discharge ambient temperature and humidity, the more ozone is produced.
してみるに、上記冷蔵庫に於いては、扉の開成
動作により庫内に外気が流入し、その結果庫内の
温度及び湿度共に上がる一方、悪臭成分について
は外気によつて薄められて濃度が薄くなることか
ら、脱臭装置を駆動しても効果的な脱臭を行なう
ことができない。 In the refrigerator mentioned above, outside air flows into the refrigerator when the door is opened, and as a result, both the temperature and humidity inside the refrigerator rise, while the concentration of malodorous components is diluted by the outside air. Since it becomes thin, effective deodorization cannot be performed even if the deodorizing device is operated.
即ち、扉の開成により庫内に外気が流入する
と、電極、誘電体が相対湿度の上昇により湿潤す
ると共に、空気放電電圧が設定値より低下するた
め、放電時の電流密度が低下し、オゾン生成量が
減少して効率の良い脱臭効果は期待できない。 In other words, when outside air flows into the refrigerator by opening the door, the electrodes and dielectric become wet due to the increase in relative humidity, and the air discharge voltage decreases below the set value, so the current density during discharge decreases and ozone is generated. Since the amount decreases, an efficient deodorizing effect cannot be expected.
冷蔵庫の扉の開成時には脱臭装置を停止させ、
扉が閉成されるとすぐに脱臭装置を駆動するので
はなく所定時間経過してから脱臭装置を駆動する
ようにすることである。
Stops the deodorizing device when the refrigerator door is opened,
Rather than driving the deodorizing device immediately after the door is closed, the deodorizing device is driven after a predetermined period of time has elapsed.

A deodorizing device that generates ozone by applying a high voltage between a high voltage electrode and a low voltage electrode, and decomposes and removes malodorous components with the ozone; This deodorizing device is linked to the opening and closing of the refrigerator door, a switch that stops power supply to the electrode when the door is opened; a timer that adds up a predetermined time from the time the door of the refrigerator is closed; A refrigerator deodorizing device comprising: a driving means that drives the electrode to start power supply to the electrode; and a refrigerator deodorizing device.

When the door of the refrigerator is opened, outside air flows into the refrigerator, diluting the malodorous components inside the refrigerator and reducing the need for deodorization. stops.

て、悪臭成分は分解され、冷蔵庫内の脱臭が行わ
れる。 Immediately after the refrigerator door is closed, the outside air that flows into the refrigerator has low odor components, so there is no need to immediately operate the deodorizing device, and the inside of the refrigerator becomes hot and humid. Even if the deodorizing device is operated, the amount of ozone generated is small and the deodorizing efficiency is poor, so the deodorizing device is stopped by the action of the timer, but after a predetermined period of time, the refrigerator is filled with malodorous components. At the same time, the inside of the refrigerator becomes low temperature and low humidity, making it easier to generate ozone. At this time, the driving means receives the output of the timer and drives the switch to supply power to the electrodes of the deodorizing device, thereby driving the deodorizing device. By driving this deodorizing device, malodorous components are decomposed and the inside of the refrigerator is deodorized.

置を停止させている。 The reason why the deodorizing device is operated after a certain period of time after the door closes as described above is because immediately after the door is closed, both the temperature and humidity are rising due to the inflow of outside air, and Since the concentration of malodorous components is diluted by the inflow of odor, there is little need for the deodorizing device to operate during this period, so the deodorizing device is stopped.

As described above, according to the present invention, ozone is generated when outside air flows into the refrigerator and the refrigerator door is opened, which does not require deodorization, and when the refrigerator door is closed, odor components fill the refrigerator. Since the deodorizing device is stopped for a predetermined period of time until ozone is easily generated, the deodorizing device is activated only when ozone is easily generated and the deodorizing efficiency is high, allowing efficient deodorizing, which saves energy. Not only can the effects be expected, but also the life of the deodorizing device can be extended.
