Patent ID: 7473872

Claim:
A cooking tool used with a heat cooking apparatus having a receiving unit capable of receiving data externally transmitted in the form of infrared rays, the cooking tool being heated by a heating unit of the heat cooking apparatus while being supported by a supporting unit of the heat cooking apparatus, the cooking tool comprising: a temperature detecting unit that generates a signal according to a temperature of an object to be cooked; a transmitting unit that transmits temperature data corresponding to the output signal from the temperature detecting unit in the form of infrared rays to the heat cooking apparatus; and a primary coil and a secondary coil, the secondary coil magnetically connected to the primary coil while the heating unit is being driven to produce electric power for operating the transmitting unit, wherein for the case where a high frequency current is caused to flow through the primary coil so that the heating unit of the heat cooking apparatus performs induction heating, the secondary coil is magnetically coupled to the primary coil by passing a high frequency current through the primary coil, and wherein the transmitting unit is provided with a rectifying portion to rectify the output voltage from the secondary coil and a stabilizing electric supply portion to stabilize the rectified output voltage from the rectifying portion.
