Document Type and Number:
WIPO Patent Application WO/2017/130336
Kind Code:
A1
Abstract:
A hand dryer comprises: a hand insertion section provided on a case (10) that forms the outer wall; a nozzle that is provided in the hand insertion section and that emits an airflow; a hand detection sensor (20) serving as a hand detection unit that continuously detects a hand inserted into the hand insertion section; a blower unit (40) that is housed in the case (10) and that generates an air current that causes an airflow to be emitted from the nozzle; and a control unit (30) that controls the operation of the blower unit (40) in accordance with a detection signal from the hand detection sensor (20). The control unit (30) calculates, from the detection signal from the hand detection sensor (20), the speed of the hand being inserted into and removed from the hand insertion section, and based on the calculated speed, adjusts a delay time for starting or stopping the blower unit (40) from when a hand is inserted into or removed from the hand insertion section. Thus, regardless of the speed that the hand is inserted or removed, water does not readily scatter outside of the product, the next user can use the device immediately, and usability is improved.
