  • Patent number: 4394557
    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.

  • Patent number: 4367387
    Abstract: A microwave oven is controlled to cause a magnetron to oscillate for a set timer time period. The timer time period is set by a device for entering a timer time period. The device comprises a displaceable operation knob provided and a code signal generator for generating a Gray code signal in association with the displaced amount of the operation knob. The generated code signal is converted into a binary coded decimal signal and is further converted into a time period signal, whereupon the same is stored as a timer time period. The magnetron is controlled to oscillate for an oscillation time period responsive to the timer time period as stored, while the set timer time period is down counted for each second in accordance with the lapse of the oscillation time period of the magnetron. The left time period obtained as a result of such down count is displayed by the digital display.
