HAND DRYER DEVICE

A hand dryer device includes nozzles to blow airflows into a hand-placeable drying portion, a blower to generate the airflow to be blown out of the nozzles, a sensor having a light-emitting element to detect the presence or absence of a hand in the drying portion, and a controller to make a hand detection determination of whether the hand is present or absent in the drying portion based on a detection result of the sensor, and control driving of the blower based on a determination result of the hand detection determination. The controller controls an intermittent driving of the light-emitting element of the sensor. In first and second driving cycles of the sensor, when a determination result in the first driving cycle and a first determination result in the second driving cycle differ from each other, the controller extends a driving period of the sensor in the second driving cycle.
