  • Patent number: 6140621
    Abstract: A toast oven is controlled by a microprocessor that is programmed to selectively determine each toasting time in accordance with a user selected toasting requirement and with an initial oven temperature. In this way the toasting time is automatically adjusted to take into account the oven temperature at the beginning of each toasting cycle. The user therefore does not have to make subjective manual adjustments to produce consistent toasting results. A time display on a panel, controlled by the microprocessor, indicates the remaining toasting time during each toasting cycle.
