| 20110088279 | DRYNESS DETECTION METHOD FOR CLOTHES DRYER BASED ON CHARGE RATE OF A CAPACITOR - A dryer having an improved automatic dryness detection circuit is provided. Wet clothing in the dryer bin contacts a sensor and causes a pulse to be sent to a microcontroller if the resistance of the clothes is low enough. The microcontroller disregards pulses which are shorter than a threshold time and counts pulses which are longer than a threshold time. The microcontroller issues a termination signal if the rate of pulses is lower than a threshold rate. | 04-21-2011 |
