(57) A hand dryer comprising a body (1) having installed in its inside a motor-blower-resistance
assembly (5) suctioning air from an inlet (6) being provided in said body and expelling
said air once heated through an outlet (7) also being provided in said body. This
dryer is characterized in that it incorporates inside the body (1) a printed circuit
board (13) comprising means (14, 15, 16, 17) by means of which the operation of the
motor-blower-resistance assembly (5) is controlled, said dryer being thus put in a
position to put up a performance of which the known dryers of the same type are incapable.
Thus through the action of some (14, 15, 17) of said means the outflowing air temperature
is automatically regulated, and by means of all (14, 15, 16, 17) of them the time
is limited during which the dryer can be kept in continuous operation each time when
used and the activation of its drive and heating unit is inhibited in case of a detection
of the presence of undesirable, stationary elements in front of the outlet (7), one
of said means (14, 15, 16, 17) totally disconnecting the dryer if its motor (12) is
out of order.
