Abstract
An iron includes a heater, a thermostat, a temperature select knob, a READY indicator, a WAIT indicator, an audible transducer, a relay, a motion detector, and a microrprocessor-based electronic control circuit. Whenever the temperature select knob is moved, an interrupting signal is supplied to the microprocessor which causes the WAIT indicator to be illuminated and the READY indicator to be extinguished. Following this operation, the READY indicator is illuminated, the WAIT indicator extinguished and a single beep produced by the audible transducer whenever the thermostat deenergizes the heater. If the READY indicator is illuminated a total of ten minutes without the motion detector sensing movement of the iron, a ten-beep signal is produced by the transducer. If the READY indicator is illuminated for a total of twelve minutes without the iron being moved, the electronic control circuit deenergizes the relay to produce an automatic shut-off of the iron.
