Claim:
A hand dryer comprising: a casing ( 1 ), a drying chamber ( 2 ) integrated in the casing for inserting hands, means for propelling air at room temperature at a high speed through an air circulation chamber towards the inside of the drying chamber, presence and proximity detectors ( 61 ) for the automatic actuation of the dryer when the user inserts his or her hands in the drying chamber ( 2 ), an electronic control card ( 6 ), means for collecting the water released from the user's hands during drying, at least two air outlets arranged in opposite walls of the drying chamber ( 2 ), and two flat hollow air circulation chambers ( 3 a , 3 b ) inside the casing which are parallel to the front and back walls of the drying chamber ( 2 ) and demarcated by respective pairs of mutually opposite front and back plates ( 31 , 32 ); said hollow chambers ( 3 a , 3 b ) comprising inner channels ( 33 ) for the conduction and distribution of air through the inside of said hollow chambers with a low coefficient of friction, minimizing the formation of whirlpools during its circulation through the inside of said hollow chambers, a mouth ( 36 } for the inlet of high-speed air propelled by the air propulsion means ( 4 a , 4 b ), and a plurality of air outlet orifices ( 34 ) defined in the front plates ( 31 ) of the hollow chambers which project air simultaneously on the entire surface of the user's hands inserted and held still inside the drying chamber ( 2 ); said hollow chambers ( 3 a , 3 b ) are arranged, respectively, between the front walls of the drying chamber and of the casing, and between the back walls of the drying chamber and of the casing.
