ABSTRACT:
In an automatic bread baking machine, a temperature detecting circuit and a control method thereof detect the change of a temperature during the baking of bread. According to temperature programming, a microprocessor outputs from its output terminals a high signal in a defined order onto numerous resistors. The resistors have predetermined resistor values different from each other. A temperature sensor is connected in common to the resistors. Moreover, a comparator compares the voltage across the temperature sensor to the comparator's reference voltage. The output of the comparator is connected to and monitored by the microprocessor. Consequently, the temperature detecting circuit and the control method allow for the elimination of an A/D convertor and the self-diagnostic functions for a thermistor.
