摘要： An induction heating cooker includes a surface, a heating coil for inductionally-heating a load pan, an inverter for supplying a high-frequency current to the heating coil, an infrared detector which detects infrared radiation emitted from the load pan and is located under a top plate, a first temperature detector for detecting a temperature of the load pan based on an output of the infrared detector, a heating controller for controlling a power output from the inverter, a thermo-sensitive element for receiving heat from the top plate, and a second temperature detector for detecting a temperature of the load pan based on an output of the first thermo-sensitive element. This induction heating cooker detects a temperature change of the load pan accurately by detecting an infrared radiation from the load pan, and detects the temperature of the load pan by the heat conduction from the pan even if ambient light enters.

摘要： An induction heating device prevents an object to be heated from being displaced and buoyed from a mounting surface due to an mutual action of repulsive forces between the object to be heated and an induction heating coil. The induction heating device includes a source-current detector for detecting a source current input to a high-frequency inverter including the induction heating coil and an inverter circuit, a source-current change detector for measuring a change against time of a magnitude of the source current to detect a displacement and buoying of the object to be heated, such as a cooking pot, and a change examining unit. The controller controls an output of the high-frequency inverter in response to a detection result of the change examining unit. The induction heating device prevents the cooking pot from being displaced and buoyed even if the pot is not touched by a user at startup of heating or during the heating operation, and is inexpensive and safe.

摘要： An induction heater having a safety function of lowering or stopping the heating power when an object to be heated moves, the safety function hardly interfering with the cooking activities of a user is provided. The induction heater includes an inverter circuit, an output detection section for detecting the magnitude of the inverter circuit, a first movement detection section, and a storage section for storing a control value before the first movement detection section detects a movement of the object. In a reach control mode, the output of the inverter circuit is gradually increased to a target. In a stable control mode, the output of the inverter circuit is maintained at the target. When the first movement detection section detects a movement of the object, a control section shifts to a first output mode in which a control value derived from the stored control value is output.

摘要： A detector is operable to detect a displacement of a load by an ascending force based on a period of time from a time a heating output of an inverter drops from a predetermined level to a first level, to a time the heating output returns back to a second level larger than first level. Thereby, the detector distinguishes an intentional removal of the load from the displacement of the load by the ascending force. An induction heater including the detector reduces the displacement of the load by the ascending force and stops the heating of the load when the load is removed intentionally.
