Abstract
A control circuit of a programmable coffee maker includes an input unit for inputting a preset brewing time, a heater controller for controlling electrical connection between an electric heating device and a power supply, a sensor unit for providing a cancel signal when temperature at a supply pipe connected to a water reservoir and heated by the heating device reaches a predetermined critical temperature, and a processor having an internal clock with a current time output. The processor controls the heater controller to make electrical connection between the heating device and the power supply when the preset brewing time coincides with the current time output, and cancels the preset brewing time and controls the heater controller to break the electrical connection between the heating device and the power supply after the processor receives the cancel signal from the sensor unit.
