There is.

FIG. 4 schematically shows a control circuit for the microwave oven as described above. A microcomputer 30 controls the magnetron 15 based on an input cooking program. Reference numeral 31 denotes a paper piece detector, such as a photocoupler, which is not shown but is provided in the setting section 17 and detects whether a piece of paper 2 is set in the setting section 17 and supplies this detection information to the microcomputer 30. . Reference numeral 32 denotes a hot air generating section, which includes the hot air blower 21 as a component, generates hot air, and blows it out from the blower 21.

Reference numeral 33 denotes a heating (cooking) program reading device, such as an optical character reading device, which includes the reading head 22 as a component and reads the cooking program P on the piece of paper 2 set in the setting section 17. A food temperature detector 34 detects the temperature of the food to be cooked placed on the shelf board 14 and supplies this detected temperature information to the microcomputer 30. The digital display 16 displays the elapsed cooking time and changes in the temperature of the food to be cooked based on the calculation results of the microcomputer 30.

Therefore, when performing the prescribed cooking now,
The packaging bag 1 containing the food to be cooked necessary for cooking is taken out of, for example, a refrigerator. Then, cut out the piece of paper 2 attached to the packaging bag 1 along the perforation line, and insert the piece of paper 2 into the set section 17 as shown in FIG.
Set to Then, the photocoupler 31 detects the piece of paper 2 in the setting section 17, hot air is blown out from the hot air outlet 21, and the reading head 22 starts the reading operation. Therefore, if the piece of paper 2 is set in the setting section 17 and moved in the direction of the arrow shown in the figure, the ice and water droplets that had adhered to the piece of paper 2 due to being stored in the refrigerator will be removed from the hot air blower 21.
