  • Patent number: 6931759
    Abstract: An apparatus for sensing a dryness degree in an exhaust type clothes dryer and a control method using the same, includes an electrode sensor for sensing a clothes drying state based on the humidity of the clothes in the drum, and a thermistor for sensing the temperature of the air discharged after drying the clothes. By comparing the clothes drying state and discharged air temperature, the operation of the dryer is controlled, so that the drying of clothes can be accurately performed, thus to improve efficiency and performance of an exhaust type clothes dryer.

  • Patent number: 6779279
    Abstract: A dryer having a filter sensing system that warns a user that a filter requires servicing is provided. The dryer includes a drum that retains laundry. Hot air is drawn through the drum (for drying) and out an exhaust casing having a filter for removing lint and other particles. The temperature difference of the air in front of the filter (on the drum side) and behind the filter is determined using temperature sensors. When that temperature difference exceeds a predetermined threshold, a control unit causes a notice unit to produce a warning signal that informs a user that filter service is required.
