Abstract
Abstract An electronic controlled heat cooking apparatus having a plurality of heating mode designating keys and a timer allotted to each of a plurality of blocks for setting heating conditions of an oven. A random access memory included in a microprocessor stores which block's heating mode designating key was first operated from the plurality of blocks and also stores the set heating mode and the time period set by the timer of that block. The microprocessor is responsive to an operation of a start key to select the heating modes of the oven in accordance with the order as stored in the random access memory and enable the oven's appropriate heat source in the selected heating mode for the set time period of the corresponding timer. Each timer has a displaceable operation knob, and a digital display is provided to display the timer time period information set by the knob.
