Claims

[Scope of utility model registration request]

(1) In an induction heating device in which multiple coils are arranged from the insertion side to the exit side of the workpiece, the power distribution of each coil is gradually increased from the insertion side to the exit side of the workpiece, and An induction heating device characterized by being provided with a power supply or power adjustment means that can adjust the power supplied.

(2) The induction heating device according to claim 1 of the utility model registration, characterized in that the coil is wound more closely from the insertion side to the exit side of the workpiece, thereby making the power distribution and the cloth tapered. .

(3) The induction heating device according to claim 1, wherein the coil is multi-wound so that the power distribution is tapered from the insertion side to the exit side of the workpiece.

(4) Utility model registration claim 1, characterized in that the coil is formed in a tapered shape so that its diameter gradually decreases from the insertion side to the exit side of the workpiece, so that the power distribution is tapered. The induction heating device described.

(5) Utility model registration claim 1, characterized in that a plurality of coils are seamlessly connected by sequentially inserting the outlet side of the workpiece of each coil into the insertion side of the workpiece of an adjacent coil.
