PURPOSE: A humidity measuring device of a dryer is provided to measure humidity through a sensor at the front and the rear of a drum, to cause direct friction between the sensor and a dried object by installing the sensor at a slope and thus to accurately measure the humidity from a drum. CONSTITUTION: A humidity measuring device of a dryer(100) comprises a front supporter(40), a back supporter(50), a front sensors(140,240), a back sensor(150), and a controller(130). The front end of a drum is rotatably supported on the front supporter. The back end of the drum is rotatably supported on the front supporter. The front sensor is installed at the front supporter to measure humidity. The back sensor is installed at the back supporter to measure humidity. The controller is connected to the front sensor and the back sensor. The controller receives the measured humidity. The controller controls a heater for heating the air incoming to the drum. |
