PURPOSE:To prolong the service life of illuminating light source by saving any needless lighting by means of lighting an illuminating light source behind a liquid crystal displayer only when a heating cooker is charged with foodstuff to be cooked. CONSTITUTION:A controller 26 controls such operations as setting up menu, starting, stopping and cancelling a cooking operation corresponding to the input from an input means 29 comprising a start key 4, a category selective key 6 and a clear key 7 to set up cooking time and temperature by means of A/D converting any analog input from a timer volume 9 and a temperature volume 10. Through these procedures, the controller 26 may receive any detecting signals from a temperature sensor 30, a humidity sensor 31 and a volume sensor 12 to perform semiautomatic or automatic cooking operations conforming to said cooking sequences. Besides, the controller 26 may start illumination on receiving the signals from volume sensor 12 by means of turning a power supply circuit 32 of illuminating light source 21 ON. |
