Abstract:
1. A microwave induction heating device for heating a portion of an object, comprising: microwave oscillation means for oscillating a microwave to heat the object by microwave induction; an electrode for irradiating the object with a microwave oscillated from the microwave oscillation means in a contact state with the object; a first temperature detecting means separate and spaced from the electrode and operable to detect a temperature of the object outside the electrode, the electrode having a microwave irradiating unit for oscillating the microwave, a second temperature detecting means disposed on an external surface of the microwave irradiating unit and a contact member, the contact member being coated on the external surface of the microwave irradiating unit and the second temperature detecting means being operable to contact the object during heating; and the microwave oscillation means being operable to change a frequency of the microwave oscillated by the microwave oscillation means based on temperatures detected by the first and second temperature detecting means.
