Abstract
In a hand drier for drying the hands by blowing hot wind at the extended hands, a drying time is contracted. Unpleasant feelings are avoided by excessively increasing the hot wind temperature.
By perceiving the hands extended to the drying portion 2 with a hand sensor 9, the air is sucked by the fan 7 and the air is heated by the heater 8 to discharge the air to the drying portion 2. The Peltier effect element 6 is arranged in a ventilation passage from the air sucking opening 4 to the discharging opening 3 so that the heat sucking side A may be thermally exchanged for the air within the ventilation passage 5, so as to remove the humidity of the air.
