Description

  The present invention relates to a work coil assembly for electromagnetic induction heating, and more particularly, to a plurality of assembly trunks that form one piece so that food can be cooked using an electromagnetic induction heating method. The present invention relates to a work coil assembly for electromagnetic induction heating in which an assembly provided around the outside is configured, and a coil and a magnet are provided around the outside of the assembly.

Generally, the induction range is an electromagnetic induction heating type next-generation electronic cooking appliance that cooks food using magnetic force. The electromagnetic induction heating method means an application of high-efficiency magnetic field induction technology. When an alternating current is applied to the induction heating coil inside the induction range, magnetic lines are generated. This is a direct heating method in which an infinite eddy current is generated at the center of the magnetic field lines and the cooking vessel generates heat by the electrical resistance of the metal, and the induction range using this has no combustion flame. Therefore, it can be said that it is a next-generation electronic cooking utensil having stability, economy and cleanliness as compared with existing cooking utensils.
An induction heating coil used in this type of induction range is a coil formed by twisting a plurality of copper wires into a circular shape, and engaged with a support plate on which a number of ferrite cores are attached. Configure the plate.

Depending on the type of induction range, the induction heating coil can be shaped like a disk or a container with a recessed central part, or a circular shape with a central space on the disk, depending on the shape and capacity of the induction range. Presents various shapes.
Induction heating coils with copper stranded wires wound into a circular plate are attached to the support plate. After the coil is attached to the support plate, the coil will not be disturbed or frayed in order to maintain a certain shape. It has a shape that is fixed by an adhesive or the like.
As a method for fixing the induction heating coil integrally, it is possible to use a copper twisted wire coated with a self-bonding varnish after coating an enamel varnish which is an insulating coating layer on the copper wire. After winding the copper stranded wire into a circular plate shape, heat is applied to the copper stranded wire to cure the coated self-bonding varnish to form a circular plate shape fixed integrally.
