A hand dryer, used to dry wet hands with high-speed jets, has the conventional nozzles that spout in the fixed direction. Because the jets from those nozzles can't reach all area of hands, some water remains partially and the drying time becomes longer. To shorten the drying time, we have studied the reciprocated jet that removes the water on hands effectively. The behavior of the water separation was observed by high speed camera, and the mechanism of water removal was modeled. As a result, the developed product improves the drying time from 8 seconds of the previous product to 3 seconds.
