Abstract

A device wherein food can be warmed by means of induction, said device comprising at least one secondary coil which is formed from a current conductor, whereon at least one heating element is connected. The invention also relates to a device which is used to transfer energy in a device in order to warm food by means of induction, said device comprising a primary coil which is connected to a voltage source and which is formed from a current conductor. According to the invention, the primary and secondary coil is cast into a coil body by casting means, and the insulating casting means exhibits a coefficient of thermal expansion which essentially corresponds to the coil body.
