Abstract

Abstract A cooking apparatus comprising a cooking apparatus housing having a heating chamber which allows an oven-cooking mode by the operation of a heater, and a temperature sensor for detecting the temperature inside the heating chamber, a first control section for comparing the temperature in the heating chamber detected by the temperature sensor with a preset cooking temperature, and for controlling the heater in accordance with the comparison results, a first setting unit for setting the cooking temperature in steps in response to the operation of a temperature setting member, a second setting unit for initially setting the cooking temperature at a predetermined value which is frequently used before a setting operation of the first setting unit, and a second control section for controlling the operation time of the first control section in accordance with a preset cooking time.
