Support structure for object to be heated

A support structure for an induction heating device that includes a working coil configured to heat an object, the support structure comprising:

• a housing including an upper surface that is recessed downward and that is configured to seat the object;
• a repeating coil that is located inside the housing, that is configured to generate magnetic induction or magnetic resonance with the working coil, and that is configured to heat the object on the upper surface of the housing based on magnetic induction or magnetic resonance with the working coil;
• a compensation capacitor located inside the housing and connected to the repeating coil, the compensation capacitor being configured to control output of the repeating coil;
• and
• a temperature sensor located inside the housing and configured to sense a temperature of the object on the upper surface of the housing,
• wherein the repeating coil is arranged between a lower surface of the housing and a horizontal portion of the upper surface of the housing, the upper surface being configured to contact the object,
• wherein the temperature sensor is arranged at a central region inside the housing and spaced apart from the repeating coil by a predetermined distance in a horizontal direction of the repeating coil, and
• wherein the upper surface of the housing comprises:
• a first horizontal portion that extends in the horizontal direction with respect to the lower surface of the housing,
• a curved surface portion that has a first end connected to an end of the first horizontal portion and that is curved downward to the lower surface of the housing,
• a vertical portion that extends from a second end of the curved surface portion in a vertical direction with respect to the lower surface of the housing, and
• a second horizontal portion that extends from an end of the vertical portion in the horizontal direction with respect to the lower surface of the housing.
