ABSTRACT:
A control circuit for a drier wherein a buzzer is provided for signalling termination of the normal drying cycle or operation of the drier in an anti-wrinkle cycle. When utilized to signal the end of a normal cycle, the buzzer provides a short time duration signal and when utilized to indicate the operation of the drier in the anti-wrinkle cycle, the buzzer provides a longer duration signal at periodic intervals during the cycle. Control of the buzzer is by a single cycle switch connected in cooperation with a timed switch for controlling operation of the drier drive motor, and a centrifugal switch also provided for controlling operation of the drier drive motor. The cycle switch may be a double throw switch and may have an associated pulser mechanism for effecting the desired intermittent operation of the buzzer for indicating the anti-wrinkle cycle.
