Abstract
A system and method for sensing the dryness of clothing articles in a clothes dryer. In one embodiment, the clothes dryer uses a temperature sensor and a phase angle sensor to determine the dryness of the clothing articles as a function of the heated air temperature and the motor phase angle. In another embodiment the clothes dryer uses a humidity sensor to determine the dryness of the clothing articles as a function of the humidity of the heated air temperature. In a third embodiment the clothes dryer uses a temperature sensor, a phase angle sensor, and a humidity sensor to determine the dryness of the clothing articles as a function of the heated air temperature, the motor phase angle, and the humidity of the heated air temperature.
