1. A temperature control device, comprising:
a temperature estimation unit configured to estimate a temperature of an object being heated by an induction heating coil, the temperature being estimated based on a frequency of a drive signal supplied to an inverter connected to the induction heating coil;
a frequency generation unit configured to set the frequency of the drive signal based on the temperature estimated by the temperature estimation unit, a detected temperature of the object from a temperature sensor, and a target temperature for the object; and
a power estimation unit configured to estimate a power supplied to the induction heating coil based on the frequency of the drive signal, wherein
the temperature estimation unit additionally estimates the temperature of the object based on the estimated power supplied to induction heating coil.
