BACKGROUND OF THE INVENTION
The present invention relates to an electrode mounting mechanism for an electrostatic field fryer that forms an electrostatic field in an oil tank and cooks food, and an electrostatic field fryer that insulates and mounts a cooking casing.
[0002]
[Related technologies]
It is known that the freshness of edible oil can be maintained for a long period of time by using a fryer oil tank as an electrostatic field atmosphere when frying and cooking food using a fryer. When an electrostatic field atmosphere is formed in an oil tank, a net-like electrode to which a high voltage is applied from a high-voltage transformer is attached to a support net provided on a heat pipe in the fryer oil tank, separated by an insulating member, and the oil in the oil tank is attached. An electric field is applied to.
[0003]
Moreover, in a general fryer, there exists a 2 tank type fryer which divided | segmented the oil tank into two with the partition wall. When cooking ingredients consisting of many small pieces, such as fried potatoes and shirasu, using one of the oil tanks of this fryer, the ingredients are stored in a casing formed of a net-like member, and this casing is divided into oil tanks. Cooking is performed so as to engage the upper end of the wall. Even in such a fryer, when an electrostatic field is formed in the oil tank, it is necessary to form a stable electrostatic field.

[Problems to be solved by the invention]
In this case, when the electrode network moves on the support network and protrudes from the peripheral edge, the electrostatic field is not formed due to contact with the wall surface of the oil tank. Further, when the casing is directly engaged with the partition wall, electrons emitted from the electrodes are transmitted to the wall surface of the oil tank through the casing, so that a stable electrostatic field is not formed.
