Abstract

A hand dryer for drying a user'"'"'s hands by means of airflow discharged through an air outlet on the hand dryer. The airflow is generated by a motor-driven fan unit which is spring-mounted on a fixed part of the hand dryer via a plurality of coil springs.

Claims

1. A hand dryer for drying a user'"'"'s hands by an airflow discharged through an air outlet on the hand dryer, the airflow being generated by a motor-driven fan unit, the fan unit being spring-mounted on a fixed part of the hand dryer via a plurality of coil springs.

2. The hand dryer of claim 1, wherein the fan unit comprises a fan for generating the airflow, the plurality of springs comprises two sets of springs, and the two sets of springs are spaced axially along the axis of rotation of the fan.

3. The hand dryer of claim 2, wherein springs extend at an angle to the axis of rotation of the fan.

4. The hand dryer of claim 3, wherein the springs in a first set each extend at a first angle to form a respective frusto-conical spring configuration, and at least some of the springs in the second set also extend at the same, first angle to form a respective frusto-conical spring configuration.

5. The hand dryer of claim 4, wherein a first group of the springs in the second set extend at the first angle to form a first frusto-conical spring configuration and a second group of the springs in the second set extend at a second angle to form a second frusto-conical spring configuration.

6. The hand dryer of claim 5, wherein the springs in the first group each has a first spring constant and the springs in the second group each has a second spring constant, different from the first spring constant.

7. The hand dryer of claim 6, wherein the first group of springs are located on one side of the fan unit, and the second group of springs are located on an opposite side of the fan unit.

8. The hand dryer of claim 7, further comprising a discharge nozzle on one side of the fan unit for discharging the airflow outwardly away from the fan axis, the discharge nozzle being located on the same side of the fan unit as the second group of springs.

9. The hand dryer of claim 8, wherein the discharge nozzle is located axially nearer the second set of springs.

10. The hand dryer of claim 1, in which the springs are extension springs.

11. The hand dryer of claim 10, in which each spring is pivotally mounted at one end to the fan unit and pivotally mounted at its other end to the fixed part of the hand dryer.
