Abstract:
1. A hand drying apparatus comprising: a high pressure airflow generator configured to generate high pressure airflow; a nozzle that discharges the high pressure airflow generated by the high pressure airflow generator; a drying space that has a hand insertion portion having wall faces that allow insertion and pulling-out of hands and is formed so hands inserted through the hand insertion portion are dried by the high pressure airflow discharged from the nozzle; at least one hand detector constituted of an infrared light emitter and an infrared light receiver configured to detect hands inserted into the drying space that are arranged on a same wall face of the drying space, wherein driving of the high pressure airflow generator is controlled based on a detection signal from the hand detector; and an infrared light absorber whose infrared light reflectivity is smaller than that of hands and absorbs infrared light, formed on at least a portion of a wall face of the drying space unit that is opposed to the infrared light emitter of the hand detector.
