<p>A hand dryer device. This device belongs to the type which has a turbine that is activated by a motor that takes in air at room temperature makes it pass through a spiral, expels it at greater speed through an outlet nozzle and is characterised because the spiral (1), houses a motor turbine (3) at the beginning (6) of the air inlet area (2) surrounding the centrifuge wheel (4) of the turbine, having a spiral configuration (7) in which the section progressively increases until it connects to the outlet duct (8), and is then finished off with a progressive narrowing (11) that ends with the air outlet nozzle (12). All of this allows the device to have reduced dimensions and consumption and that, in addition takes maximum advantage of the flow-dynamic features.</p> |
