  • Patent number: 7446287
    Abstract: An induction heating cooker has a top plate, a heating coil, an inverter circuit, a pot type discriminator, a non-magnetic-metal buoyancy reducing plate having a high electrical conductivity, an infrared sensor, a temperature calculator, and a controller. The pot type discriminator judges whether a pot is made of a non-magnetic metal material having a high electrical conductivity, or a magnetic metal material or a non-magnetic metal lower in electrical conductivity than aluminum. The temperature calculator calculates the temperature of the pot from an output from the infrared sensor that detects infrared radiation from the pot. The controller controls an output from the inverter circuit according to a calculated temperature by the temperature calculator, and, when the pot is judged to be made of a non-magnetic metal material by the pot type discriminator, nullifies temperature detection made by the temperature calculator.
