摘要： A hand dryer, suitable for anchoring to a wall, the hand dryer comprising a housing that is equipped inside with a pump configured to deliver air downward; an electronic unit configured to control the functioning of the dryer; an axial-flow pump oriented vertically inside the housing; a convergent nozzle configured for channeling and accelerating air, delivered by the axial-flow pump, from an upper air intake opening to a lower outlet opening, wherein said convergent nozzle is aligned coaxially and is in the vertical direction with the axial-flow pump; and at least one air outlet nozzle end mounted on the lower opening of the convergent nozzle, and which has a surface opposite the direction of the circulation of the air, equipped with at least one opening with a cross-section that narrows in the direction of the air outlet and that causes an additional acceleration of the air driven through the convergent nozzle to the outlet opening with a low noise level.
