Abstract
A control is provided for a fabric drying machine and includes selection apparatus operable for initiating a fabric drying cycle having a dryness sensing operation. The control includes a microcontroller for controlling the fabric drying cycle as initiated by the selection apparatus. A power supply is provided for energizing the control and sensors are associated with the fabric drying machine for completing an electrical current path through wet fabrics or other conductive materials during the dryness sensing operation. Electrical circuitry interconnects the sensors and the microcontroller. The circuitry is operable for providing a series of input signals to the microcontroller upon completion of an electrical current path across the sensors and indicative of a dryness condition of the fabrics of less than a predetermined dryness and is further operable for differentiating between contact by wet fabrics and metallic objects. Counting apparatus is associated with the microcontroller for accumulating a count of the input signals, the microcontroller being responsive to at least a predetermined number of input signals in a predetermined sensing period for continuing the fabric drying cycle and repeating the predetermined sensing period and responsive to less than the predetermined number of input signals in the predetermined sensing period for initiating termination of the fabric drying cycle.
