1. An apparatus for sensing dryness degree in exhaust type clothes dryer comprising:
- a humidity sensing unit positioned inside a drum and sensing a dryness state of clothes by allowing a voltage value to be changed according to the humidity of clothes;
a temperature sensing unit positioned at the side of an exhaust duct of the drum, drying the clothes and sensing a temperature of the air being exhausted; and
a control unit for receiving sense signals from the humidity sensing unit and the temperature sensing unit and determining a dryness degree of the clothes.

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.
