Patent ID: 8426782

Claim:
An induction heating device comprising: a top plate that is provided on an upper face of a main body and adapted to have a to-be-heated object placed thereon; a heating coil that is provided at a lower part of the top plate and that heats the to-be-heated object; a plurality of sensors including a first sensor and at least one second sensor, each of the plurality of sensors being provided at the lower part of the top plate and sensing a temperature of the to-be-heated object; at least one display unit including a first display unit, the first display unit being disposed on the top plate and showing a position of the first sensor; a temperature calculator that calculates a temperature of a bottom face of the to-be-heated object based on an output from at least one of the plurality of sensors; a to-be-heated object determinatioin section that determines an absence of the to-be-heated object aboe the first sensor; and a controller that controls a power outputted to the heating coil in accordance with an output from the temperature calculator, wherein: the first sensor is decentered from a center of the heating coil to a position closer to a front side of the main body of the induction heating device, the first sensor is located at a position to sense a higher temperature of a part of the to-be-heated object, the higher temperature being higher than a temperature of a part of the to-be-heated object above the center of the heating coil, only the first sensor of the plurality of sensors has a display unit that shows sensor position, only one first display unit is provided for each heating coil, and the controller limits the power outputted to the heating coil by reducing the power outputted to the heating coil or stopping the power from being outputted to the heating coil when the to-be-heated object determination section determines the absence of the to-be-heated object above the first sensor.
