Abstract (en)
A heating apparatus such as microwave ovens includes an electric heater (15), a magnetron (16), a thermistor (8) sensing the atmospheric temperature in a cooking chamber (6) and generating a voltage signal and a control device including CPU (11). The voltage signal is read from the thermistor (8) by the control device at predetermined intervals in the condition that both of the electric heater (15) and the magnetron (16) are deenergized. A read temperature corresponding to the read voltage signal is stored in a first memory (14a). When the difference between the temperature stored in the first memory (14a) and the temperature read by the control device is within a predetermined range, the temperature read by the control device is stored in a second memory (14b). Heating constants set by a user are compensated for based on the read temperature stored in the second memory (14b). The control device controls the output of the magnetron (16) based on the compensated heating constants. <IMAGE>
