渦電流式発熱装置
Document Type and Number:
Japanese Patent JP6651880
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an eddy current type heating device which has high heat recovery efficiency, and can reduce a thermal stress occurred in a heating member even when a heating member becomes high.SOLUTION: An eddy current type heating device 1 comprises: a rotational axis 3; a heating member 4; a coupling member 8; a plurality of permanent magnets 5; a magnet holding member 6; and a thermal recovery mechanism. The rotational axis 3 is rotatably supported by a non-rotational part. The heating member 4 has a cylindrical shape, and encloses the rotational axis 3. The coupling member 8 couples the rotational axis 3 and the heating member 4. The coupling member 8 includes a main body part 8A and a plurality of arm parts 8B. The main body part 8A has a ring shape, and is fixed to the rotational axis 3. The arm part 8B is extended from the main part 8A, and is fixed to the heating member 4. The arm part 8B is curved. The permanent magnet 5 is opposite to the heating member 4 while having a space. The permanent magnet is so arranged that the magnetic poles alternately differ. The magnet holding member 6 holds the permanent magnet 5, and is fixed to the non-rotational part.SELECTED DRAWING: Figure 2
