  • Detection of synthetic fabric loads in an automatic dryer
    Patent number: 7080464
    Abstract: A method for detecting the presence of a synthetic fabric load during an automatic drying cycle in an automatic dryer avoids premature termination of the automatic drying cycle and ensures that the synthetic fabric items are dried according to a user's desired dryness level. The presence of the synthetic fabric load is detected by determining a duration of a first heating cycle, determining a duration of a second heating cycle, and determining the presence of the synthetic fabric load based on the durations of the first and the second heating cycles.

  • Method for energy efficient control of a dryer of clothes
    Patent number: 6199300
    Abstract: A method and apparatus for controlling the heat input of a dryer where the initial heat input to a clothes load is set at full power until a first predetermined temperature or time condition occurs. The heat input of the dryer is then reduced to in order to reduce power consumption while effectively removing moisture from the clothes load. When the moisture content of the clothes load falls below a predetermined amount, full heat input is once again applied to remove remaining moisture in the clothes load.
