First Claim
Patent Images
1. Hand dryer (1) comprising:
- a housing (2);
a volume (3) for receiving the hands (4);
a circuit for pumping air;
a drive motor (5) which drives a fan (T) arranged in the circuit provided with a rotor (6) and a stator (7);
a hand presence sensor (8) in the volume (3);
operation control means (9);
wherein the control means (9) are configured for operating at least in two operating regimes;
a normal operating regime wherein the motor (5) pumps the air for drying the hands and which is activated by the sensor detection (8);
a motor heating operating regime (5) wherein the stator (7) and/or the rotor (6) of the motor (5) are fed for increasing its/their temperature and maintain it to a predetermined temperature for accumulating heat which is activated by no detection of the sensor (8);
such that at the start of the normal operating regime, the motor (5) is provided with stored heat for ensuring that the air exits already heated.

Abstract
Hand dryer 1 wherein the control means 9 are configured for operate at least in two operating regimes, a normal operating regime wherein the motor 5 pumps the air for drying the hands and which is activated by the sensor detection 8 and a motor heating operating regime 5 wherein the stator 7 and/or the rotor 6 of the motor 5 are fed for increasing its temperature and maintain it to a predetermined temperature for accumulating heat which is activated by no detection of the sensor 8, such that at the start of the normal operating regime, the motor 5 has stored heat for ensuring that the air exits already heated.
