Claims

[Claims for Utility Model Registration] 1. A pair of spaced apart primary windings 10A, 10B which are wound a predetermined number of times in a coil shape in a plane, with insulating plates 30, 30 interposed between the primary winding 10.
A secondary winding 20 is provided which is wound in a coil shape in a plane with a predetermined number of turns smaller than the number of turns of the primary windings 10A and 10B, and an insulating plate 30,
30 and each central opening 15a, 15 of the secondary winding 20
A disk type transformer for high-frequency induction heating, characterized in that the outer peripheral portion of the transformer is surrounded by a core 40 made of ferrite or the like. 2. The primary windings 10A, 10B are made of hollow electrolytic copper pipes 11, through which cooling water passes from one end to the other, and the secondary windings 20 are made of hollow pipes 11 of electrolytic copper.
A passage 22 consisting of a hollow 21 made of a single turn of electrolytic copper along the inner and outer peripheral contours of 10B, into which cooling water passes.
2. The transformer according to claim 1, wherein the transformer is formed of: 3. The primary windings 10A, 10B have taps 2a to 5a, 2b to 4b at a plurality of different turns, and a high frequency current is inputted from a selected pair of taps. Trance.
