Abstract: An induction heating apparatus includes: a core that has a pair of magnetic poles and transfers magnetic flux; a coil generating magnetic flux; conductors adjacently provided on both left and right sides of the magnetic poles; and lateral magnetic members formed of a magnetic material and arranged on an outer side of end portions of the object so as to extend along the end portions. The conductors shut off the magnetic flux that flows from a center portion of the heating object, taking a detour to the end portions, permit the magnetic flux to concentrate on the center portion, and accelerate temperature rise. The lateral magnetic members introduce the magnetic flux that propagates from one surface to the other surface, detouring around the end portions to thereby mitigate the magnetic flux density in the end portions and suppress overheating.

Abstract translation: 感应加热装置包括：具有一对磁极并传递磁通的芯; 产生磁通的线圈; 相邻地设置在磁极的左右两侧的导体; 以及由磁性材料形成并且被布置在物体的端部的外侧上以沿着端部延伸的横向磁性部件。 导体切断从加热物体的中心部分流出的磁通，绕着端部弯曲，允许磁通集中在中心部分，并加速温度上升。 横向磁性部件引入从一个表面传播到另一个表面的磁通量，围绕端部进行迂回，从而减小末端部分的磁通密度并抑制过热。
