Abstract

PURPOSE: To reduce an error generated upon setting the heating time by adding a function for selecting the heating time to a cooking card.
CONSTITUTION: When a cooking card 6 is returned to thr original position by placing the card in a card holder 5, only a high-frequency heating switch is operated because an extraction part 6-a is not provided in the card 6, and this signal is memorized. Any of switches 1-d and 1-e for selecting the heating time is not operated and the control input of any of both switches becomes a zero level, and the constant of the division is selected to 30. Accordingly, the transfer distance of a knob 3 is made maximum by a variable device 2, and the value of 150min is set in a gray code. This value is converted into a binary code, and then supplied to a division circuit 9 wherein it is converted into the value of five minutes and supplied to an input terminal A4 of a control circuit 8. That is, even when the transfer distance of the knob 3 is maximum, the heating time of five minutes is established.
