Abstract

A hand dryer includes a housing including a hand insertion portion and nozzles communicating with the hand insertion portion, a high-pressure air stream generation device placed inside the housing, hand detection sensors detecting a user's hand inserted into the hand insertion portion, a control unit that, when the hand detection sensors detect the user's hand, operates the high-pressure air stream generation device to cause an air stream to jet out from the nozzles, and a drain tank collecting droplets blown off the user's hand and scattered in the hand insertion portion. The hand dryer includes a drain conductive plate placed to face the top surface of the drain tank and a control circuit detecting the water level of the drain tank based on capacitance generated in the drain conductive plate.
