BEST MODE FOR CARRYING OUT THE INVENTION The present invention is particularly excellent in high insulation and capable of applying a high voltage safely. For example, a weak current of 20 mA or less and a current of 1 kV to 15 kV can be applied.
Even if a high voltage of about 5 kilovolts, preferably about 5 kilovolts to 15 kilovolts is applied, an electric field of a weak current and a high voltage is uniformly formed without generating oil fumes or burning of the electrode plate, electrode rods and electrode wires. I can do it. Provided is an electrode structure as an electric field forming device. That is, the present invention is an electric field forming apparatus for forming a strong electric field (electric field) by applying a weak current high voltage, covering an electrode plate and an electrode rod with a coating material, and forming a weak current high voltage generating means at an end. The power supply unit is connected to the anode terminal of the transformer. By using an electrode plate and an electrode rod and connecting a voltage applying line using ceramic or enamel as a coating material, a coating having extremely high insulation properties and excellent heat resistance can be easily obtained.

An oil tank 3, a support section 4, a power supply section 5, and a heating section 6 are provided.

The electric field forming apparatus includes an electrode unit 1 and a voltage applying unit 2. The electrode section 1 and the voltage applying section 2 are made of, for example, a plate (including punching metal) such as an iron plate, a stainless plate, an aluminum plate, or a copper plate having a thickness of about 1 to 5 mm, or a conductive material such as a round bar or a square bar. Is entirely coated with a coating material such as ceramic or enamel having a thickness of about 1 mm to 5 mm. By making the coating material ceramic or enamel, it is possible to suppress or prevent the generation of harmful substances such as environmental hormones. Thus, the outside is insulative but the inside is conductive. Further, the electrode section 1 and the voltage applying section 2 have connection portions for connecting them. For the connection portion, for example, a convex or concave thread is cut, or an appropriate connection structure such as a fitting structure can be adopted. This connecting portion is not coated with ceramic or enamel and becomes conductive.

For example, in order to cover the electrode plate and the electrode rod of the electric field forming device with an insulating material, it is most preferable to cover with a ceramic or an enamel as described above. It is also possible to form an insulating structure by winding or covering an insulating or heat-resistant tape or tube with the above.

Further, the electrode section 1 and the voltage applying section 2 may mix an object that generates far infrared rays into a ceramic or enamel material. By the use of far-infrared rays, the oil can be activated, the oil can be mellowed, and the umami components of the food can be extracted. Furthermore, even when frying at a relatively low temperature, oil can be drained well and a crispy feeling can be maintained.

Generates a high voltage of about 15 kilovolts. The current value is, for example, 1 to 100 mA, and the voltage value is, for example, 20 mA.
It can be used as an appropriate value such as 0 V to 17 kV.

The fryer is constructed as described above, and supports the electric field forming device by the support portion 4 in the oil of the oil tank 3 so that the electrode portion 1 does not contact the wall of the oil tank 3 at a predetermined interval. Note that the voltage application unit 2 and the like may be supported and floated outside the oil in the oil tank 3 without using the support unit 4, for example. Then, the connection terminal of the voltage application unit 2 is connected to the secondary side anode of the transformer of the power supply unit 5 and installed.
