Abstract

A high-frequency induction heating apparatus is provided with a high-frequency oscillation apparatus, a heating coil, a high-frequency transformer and the like, the heating coil has a first coil through which prescribed current outputted by the high-frequency oscillation apparatus is flown, a second coil through which current different from the predetermined current is flown by the high-frequency transformer, and the first coil heats a trunk part and a bottom side part of the can body, and the second coil heats the trim side part of the can body.

First claim

The invention claimed is:

1. A high-frequency induction heating apparatus comprising:
a high-frequency oscillation apparatus;
a heating coil;
a mandrel that rotates a can body; and
a ferrite-made case, wherein
the can body is a steel can and moves while being rotated by the mandrel,
the heating coil comprises a first coil heating a first part of the can body, wherein predetermined current outputted by the high-frequency oscillation apparatus flows through the first coil,
the ferrite-made case accommodates the heating coil and surrounds a moving path of the mandrel, and
the mandrel comprises a ferrite-made ring that is adjacent to a mounting part of the can body and close to a bottom part of the case, wherein
the heating coil further comprises a second coil heating a second part of the can body, wherein current different from the predetermined current flows through the second coil by a high-frequency current transformer, and/or a third coil heating a third part of the can body, wherein current different from the predetermined current flows through the third coil by a parallel circuit.

2. A high-frequency induction heating apparatus comprising:
a high-frequency oscillation apparatus;
a heating coil;
a mandrel that rotates a can body; and
a ferrite-made case, wherein
the can body is an aluminum-made can and moves while being rotated by the mandrel,
the heating coil comprises a first coil heating a first part of the can body, wherein predetermined current outputted by the high-frequency oscillation apparatus flows through the first coil,
the ferrite-made case accommodates the heating coil and surrounds a moving path of the mandrel, and
the mandrel comprises a non-magnetic cylindrical element adjacent to a mounting part of the can body, wherein
the heating coil further comprises a second coil heating a second part of the can body, wherein current different from the predetermined current flows through the second coil by a high-frequency current transformer, and/or a third coil heating a third part of the can body, wherein current different from the predetermined current flows through the third coil by a parallel circuit.
