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.
Claims20
Hand dryer (1) comprising:
- a housing (2);
- a volume (3) for receiving 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 a volume (3);
- operation control means (9);
- wherein the operation control means (9) are configured for operating at least in two operating regimes:
- a normal operating regime wherein the drive motor (5) pumps air for drying hands and which is activated by the hand presence 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 temperature and maintain a predetermined temperature for accumulating heat activated by no detection of the hand presence sensor (8);
- such that at a start of a normal operating regime, the drive motor (5) is provided with stored heat for ensuring that the air exits heated.
