Abstract

PURPOSE:To generate the most preferable alarm upon key operation and completion of cooking operation by a method wherein a cooking unit is provided with means for applying a driving voltage to a buzzer when a key is operated, and means for applying a higher level driving voltage than that of performing the key operation upon completion of termination of cooking operation. CONSTITUTION:When an operation key is operated, a micro-computer 10 may output a logical '0' signal from an output port (a) and at the same time output a buzzer driving signal from an output port (b). Then, a transistor 13 is turned ON, a transistor 14 is turned ON or OFF to cause a driving current to in a buzzer 15. With this arrangement, the buzzer 15 is rung, for example, an operating sound of 'Pi !' is generated. In turn, upon completion of the cooking operation, the computer 10 may output continuously for several seconds a logical '1' signal and a buzzer driving signal. Then, the transistor 12 is turned ON and the transistor 14 is turned ON or OFF, a driving current flows in the buzzer 15, and for example, an alarm of 'Pi, Pi, !' is generated. In this case, a driving voltage Vdd1 has a high level.
