In FIG. 3, the fryer 40 has an oil tank 41, and an electrode plate 42 is accommodated in the oil tank 41, and a cylindrical connecting body 43 projects from the electrode plate 42 at the corner of the electrode plate 42. It is detachably attached to the projection that does not. A cord 45 extends from the connection body 43 to the high voltage transformer 46. When cleaning the oil tank 41, the electrode plate 42 needs to be taken out from the oil tank 41. At this time, the connecting body 43 is taken out from the electrode plate 42. This connection body 43 is inserted into a storage cylinder 44 attached to the rear casing 40a of the fryer. The storage cylinder 44 can be attached to any position of the fryer. However, since the oil attached to the periphery of the connecting body 43 falls, an opening for oil passage is provided at the bottom of the storage cylinder 44, and the oil tank 41 is opened from there. It is preferable to attach it to a position where it can be dropped.
[0018]
An infrared sensor 47 is attached to the front casing 40b of the fryer 40, and this sensor 47 detects when a cook enters a certain distance from the sensor 47 and shuts off the high voltage transformer 46. It is. Note that the cook can approach the fryer 40 by placing the foot switch plate 48 on the front bottom surface of the fryer 40. An oil tank 49 is a box-like one housed at the bottom of the fryer. Generally, when charging the oil in the oil tank, even it charged around the casing, while cooks and applying a high voltage (800V~2 k V) to the electrode plate 42 is weaker swings his hand to the casing also electric shock, A secondary disaster may occur. In addition, there is a risk of electric shock if the chopsticks touch the electrode while frying.
[0019]
The following measures can be considered as measures to prevent this electric shock.
[0020]
1. If the voltage applied to the electrode plate 42 is set to 200 V to 700 V, it is not necessary to subject the electrode plate 42 to insulation treatment for preventing electric shock, and the life of the oil can be extended 1.5 times or more than usual. However, in this case, since the voltage applied to the oil is low, the effect of extending the frying condition and the life of the oil is slightly inferior to the case where the voltage is increased. In this case, the entire fryer may be electrically insulated (for example, an insulating piece is attached to the leg), and a voltage may be applied to the entire fryer.
[0021]
2. Without performing insulation treatment for shock prevention to the electrode plate 42, 1 to 2 k V voltage added and the sensors such as the sensor 47 or the foot switch plate 48 is provided, cuts power when approaching cook within fryer When the cook is away from the fryer by a predetermined distance or more, the power is turned on. In this case, electric shock can be reliably prevented.
[0022]
3. As shown in FIG. 6, a ceramic plate 51 having a predetermined thickness is placed on a metal electrode plate 50, and the chopsticks used to fry the fried food are bamboo chopsticks or when iron chopsticks are used, FIG. As shown in FIG. 5, the electric shock prevention layer is formed by immersing the gripping portions 60, 60 of the chopsticks into a dough such as vinyl chloride which is an electrical insulating material. In addition, as shown in FIG. 5, the electric shock prevention layer 62 is also formed in the gripping portion 61 of the scooping net for scooping the deep-fried food. The electrode plate 50 is provided with oil passage slits 52, 52... 52, and the slits 54, 54. 55. Engaging protrusions 55, 55... 55 are formed at the corners of the electrode plate 50. The engaging protrusions 55 are engaged with engaging openings 56, 56... 56 provided at corresponding positions on the ceramic plate 51. These engagements prevent the ceramic plate 51 from being displaced from the electrode plate 50. The electrode plate 50 is preferably a good electrical conductor. Therefore, a metal plate is generally used, but the thermal expansion coefficient of the metal plate is different from that of the ceramic plate 51. Since the oil is heated to about 180 ° C., the ceramic plate 51 may be cracked if the two plates 50 and 51 are firmly fixed. Therefore, the oil is fixed loosely or the ceramic plate 51 is placed on the electrode plate 50 as shown in FIG. Is placed through positioning means (engagement protrusion 55, engagement opening 56).
[0023]
4). When the fryer is used, the power switch provided separately is turned off, the power is turned on when the fryer is not used, and no improvement in the frying state of the fried food is expected. To do. As described above, it has been confirmed that the oil has a sufficient effect in extending the life of the oil only by using the electrostatic atmosphere only when the oil is not used.
[0024]
It has been found that the oil reducing action and life extending action are increased not only by static electricity but also by ultrasonic waves, far-infrared rays, and magnetism, and the oil may be treated by a combination thereof. In order to expect a magnetic action, the electrode plate immersed in the oil tank may be composed of a magnet. This magnet may be a permanent magnet plate, or the electrode plate may be an electromagnet.
[0025]
Next, an electric field forming method in the oil tank will be described.
[0026]

The periphery of the electrode network 74 is located inside the periphery of the metal mesh 73 so that the electrode network 74 does not contact the inner wall of the oil tank. In this way, the electrode network 74 is electrically insulated in the oil tank. Will be held in a state. The electrode net 74 is not necessarily a net, and may be a stainless steel plate provided with holes for oil passage. Further, if the electrode is coated with Teflon, it is easy to handle the fried food without sticking to the electrode.
[0027]
Further, as shown in FIG. 7, if electrode plates 78, 78... 78 are provided vertically below the heat tube 71 in an electrically insulated state at a predetermined interval, and this electrode plate 78 is connected to the high voltage transformer 77, the heat tube 71. The oil located below can be reliably reduced. This is to compensate for the fact that electrons from the integrated electrode are absorbed by the heat tube 71 and only the integrated electrode 72 does not sufficiently reduce the oil at the bottom of the oil tank. A connecting column is detachably attached to a corner of the electrode network 74, and the connecting column 75 is connected to a high voltage transformer 77.
[0028]
Furthermore, as shown in FIG. 9, even if the auxiliary electrode blades 79, 79 (which may be rod-shaped) are suspended from the electrode net 74 through the hot space 71 so as not to contact the metal net 73, the oil at the bottom of the oil tank Can be reduced sufficiently.

The car is guarded on the side surface of each car 87 with an insulating material that prevents the electricity from leaking due to the surrounding wall of the oil tank coming into contact. Moreover, since it short-circuits when the cage | baskets 87 contact, it is desirable to guard between these.
[0031]
In the electric fryer, if the metal mesh 85 placed in the oil tank is insulated from the peripheral wall of the oil tank, the metal mesh 85 can also function as an electrode network. Further, it is possible to omit applying voltage directly to the car 87 and applying voltage to the electrode network 86.
