PURPOSE:To maintain a constant grilled color regardless of the number of pieces of cooked food by providing a detecting means to detect the number of pieces of cooked food, a setting means of grilled color, an electrifying determining means that determines the electrifying time by the outputs from a detecting means and the setting means of grilled color, and a load electrifying means that electrifies the load for a time period determined by the electrifying time determining means. CONSTITUTION:A voltage corresponding to the grilled color is generated at the middle point by a variable resister 38 that is interlocked to the grilled color setting knob, and said voltage is inputted to a micro computer 44 via an A/D converter 39. There are a series circuit of a resister 40 and a switch 41 and a series circuit of a resister 42 and a switch 43. In accordance with the number of pieces of cooked food, the switches 41 and 43 are opened or closed, which is inputted to the micro computer 44. The switches 41 and 43 are disposed at a suitable position under the grill 52, and they are turned on only when bread is set directly above them. The electrifying of a heater 33 is suspended by the output signal from the micro computer 44. |
