ABSTRACT:
A housing of a cooking apparatus has a heating chamber and an operation section. Cooking operation keys are arranged to allow a user to perform cooking operations in the operation section. A display is arranged in the operation section for displaying at least numerical information. A cooking time-setter is arranged to set a required cooking time in the operation section, upon rotation of the setter. An encoder is coupled to the cooking time-setter, and it generates pulse signals, the number of pulses corresponding to the angular position of the cooking time-setter. A controller is connected to the heating chamber, the cooking operation keys, the display, and the encoder. The controller executes an interruption procedure in response to the pulse signals from the encoder, counts the pulses of the pulse signals, fetches the count values as the cooking time-setting information of the cooking time-setter, and supplies the cooking time-setting information to the display. At the same time, the controller supplies a control signal, corresponding to the cooking time-setting information, to the heating chamber, in accordance with the operation of the cooking operation section.
