DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode plate and a high-voltage weak current applying apparatus using the same, and more particularly, to applying a high-voltage weak current to various objects to be processed such as foodstuffs. The present invention relates to an electrode plate effective for use in performing processing, storage, quality improvement processing, and the like of a processed product, and a high-voltage weak current applying device using the same.

[0002]

2. Description of the Related Art As a high voltage weak current applying device of this type, there is known a high voltage weak current applying device for foodstuffs disclosed in Japanese Patent Application Laid-Open No. 10-276744 as shown in FIG. As shown in FIG. 13, in the foodstuff high-voltage weak current applying device 1, a plurality of heating pipes 3 are provided below an oil tank 2, which is an installation target, and a large number of circular pipes are provided above the heating pipe 3. A current-carrying plate 4 having holes formed therein is arranged.

[0003] The heating pipe 3 and the energizing plate 4 are both immersed in frying oil. The energizing plate 4
The relay 6, the intermediate controller 7, and the high-voltage weak current generator 8 are connected via the wiring 5 covered with insulation. In addition, on the surface of the conductive plate 4, an insulating plate 9 having a circular hole formed corresponding to the circular hole formed in the conductive plate 4 is arranged. With such a configuration, a high-voltage weak current is applied from the conducting plate 4 to the frying oil in the oil tank 2, and an electric field is formed in the frying oil, thereby suppressing the deterioration and deterioration of the frying oil and the fried food.

[0004] Normally, the frying oil in the oil tank 2 is oxidized and deteriorated by receiving heat, and is liable to be discolored. Due to the oxidation of the frying oil, the fried food material is liable to be deteriorated and deteriorated. By using the food high voltage / weak current application device 1 having such a configuration, an effect of suppressing the oxidation of the frying oil and an effect of suppressing the deterioration and deterioration of the fried food are expected.

[0005]

However, in the above-mentioned conventional high-voltage weak current applying apparatus 1, the electric field in which the high-voltage weak current is generated is limited to the vicinity of the conducting plate 4. Certain oils were not exposed to an electric field of high voltage, weak current, and were difficult to suppress the oxidizing action.

[0006] Further, when the fried food is also fried at a position deviating from the periphery of the current-carrying plate 4, the action of the electric field is not exerted.
The above-mentioned problems and problems are hardly solved.

Further, although the upper surface of the current-carrying plate 4 is covered with the insulating plate 9, there is an area exposed in the lower surface and the holes of the insulating plate 9, so that moisture eluted from the fry food and oxidative polymerization generated from high-temperature oil are generated. There is a possibility that a minute electric leakage or a transformer failure may occur in a short time due to the substance adhering to the conductive plate 4.

Further, in the above-mentioned conventional example, the effect of inducing high-voltage electric field energy to penetrate high-frequency electric field energy into the fry food which is to be affected by the electric field formed by the conductive plate 4 is weak.

The problems of the prior art in which the food high voltage / weak current applying device 1 is applied to the fryer have been described above. However, even when the positive effect of the high voltage / weak current is applied to foods other than fried foods, the above-mentioned problems are not solved. It is conceivable that the problems described above also occur.

In a refrigerator and the like disclosed in Japanese Patent Application Laid-Open No. 7-296733, when an electrode is installed in a low temperature environment, a temperature difference is generated under the condition of door opening / closing and intermittent application (pulse discharge). An improper application state occurs due to dew condensation on the electrode device. This is not the case if the door is open / closed and continuous application type. However, there are many problems in practical use, and there is a problem that stable use is difficult for a long time.

Further, when such an electrode device is applied to a device arranged in oil, the object to be treated, liquid water generated from the heated oil, and an oxidized polymer adhere to the electrode device, causing an improper application state. In addition, since it is installed in high-temperature oil, cleaning is not easy, and there are many problems in practical use, and there is a problem that stable use is difficult for a long time.

When such a conventional electrode device is placed in a humid environment, it is difficult to ensure safety, malfunctions occur in a short time, and the entire electrode placement device is completely insulated. There is also a practical problem in terms of facilities.

Further, in a device to which such a conventional electrode device is applied, if there is a failure in electrical insulation, the metal of the electrode device is exposed, and thus there is a problem in safety.

As described above, in the conventional high-voltage weak current applying apparatus, problems and problems are hardly solved without consideration for the installation environment and handling of the electrode apparatus.
Specifically, there is a great possibility that moisture and fine substances adhering to the electrode device may cause a short circuit, an electric circuit failure, and a transformer failure in a short time.
