Filed: 2001-11-30
Abstract: An automatic clothes dryer has a drying cycle followed by a cool down cycle where the cool down cycle is terminated when the sensed output temperature of the dryer drum falls below a default temperature value preselected or altered by user. This permits the user to adjust the termination cool down cycle temperature to the user's preference and touch sensitivity to the warmth of clothing removed from the dryer. The user adjusts the setting of a user variable selection device on the dryer control panel to a preferred temperature signal representing the desired temperature of articles in the dryer when the cool down cycle is terminated. The dryer has a comparator that is connected to the outlet thermistor for receiving the sensed signal representing the temperature of the air leaving the drum and that is connected to the user variable selection device for receiving the user preferred temperature signal. The comparator generates a cool down cycle termination signal to end the cool down cycle when the sensed signal favorably compares with the user preferred temperature signal. The comparator is preferably embodied in a microprocessor.
