<p>In a hand drying apparatus provided with a high pressure airflow generator 2 that generates high pressure airflow; a nozzle 4 that discharges high pressure airflow generated by the high pressure airflow generator 2; a drying space forming unit that has a hand insertion portion 3 that allows insertion and pulling-out of hands and is formed with a drying space 6 where hands inserted through the hand insertion portion is dried by high pressure airflow discharged from the nozzle 4; and one or plural hand detectors 8 constituted of an infrared light emitter and an infrared light receiver for detecting hands inserted into the drying space arranged on the same wall face of the drying space forming unit, driving of the high pressure airflow generator 2 being controlled based on a detection signal from the hand detector 8, an infrared light absorber 10 whose infrared light reflectivity is smaller than that of hands and absorbs infrared lights is formed on at least a portion of the wall face of the drying space forming unit that is opposed to the infrared light emitter of the hand detector 8, so that, when a person other than a user of the hand drying apparatus approaches to a main unit, improper operations can be prevented with a high accuracy and a hand detection range is maintained widely.</p> |
