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.

Induction cooking heater

When a pan made of a non-magnetic material, such as aluminum, is used for cooking while the temperature is being controlled, a notice is made to the user to the effect that the temperature control function has been stopped and that the temperature should be manually adjusted, when the material detection section detects that the pan is made of a non-magnetic material or a pan floating phenomenon has occurred, in order to prevent abnormal increase in the temperature of the pan due to incorrect temperature detection caused by the pan floating phenomenon, a set temperature is lowered.

Induction heating apparatus

A themometer for measuring a body temperature by using infrared rays and on the basis of a measuring method in which a measurement error fluctuates depending upon the length of the measuring time including computation time. The measuring time is calculated on the basis of a required measurement error, so that a temperature can be measured in a suitable time corresponding to a required allowable error. A probe is formed of a porous structure so as to improve the heat insulating effect thereof, and an auxiliary adapter is provided to permit the thermometer to be fitted better in the earhole in spite of an individual difference in size thereof with the function of reporting a relative ovulation date based on a desired delivery date also incorporated in the themometer.
