Fan having a magnetically attached remote control

1. A fan assembly for creating an air current, the fan assembly comprising:

an air inlet;

an air outlet;

an impeller;

a motor for rotating the impeller to create an air flow passing from the air inlet to the air outlet, the air outlet comprising an interior passage for receiving the air flow and a mouth for emitting the air flow, the air outlet defining an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth;

a control circuit for controlling the motor;

a remote control for transmitting control signals to the control circuit; and

at least one magnet for attaching the remote control to the air outlet,

wherein said at least one magnet is located in the air outlet, and

wherein the air outlet comprises an annular inner casing section and an annular outer casing section which together define the interior passage and the mouth, and wherein said at least one magnet is located within a housing disposed on an inner surface of the outer casing section.

2. The fan assembly of claim 1 , wherein said at least one magnet is arranged to attach the remote control to an upper portion of the air outlet.

3. The fan assembly of claim 1 , wherein said at least one magnet comprises at least two magnets angularly spaced about the air outlet.

4. The fan assembly of claim 1 , wherein the housing comprises a pair of resilient walls extending inwardly from the inner surface of the outer casing section for retaining at least one magnet therebetween.

5. The fan assembly of claim 1 , wherein the outer casing section comprises a plurality of said housings angularly spaced about the inner surface of the outer casing section, each housing being arranged to retain a respective magnet.

6. The fan assembly of claim 1 , wherein the mouth comprises an outlet located between an external surface of the inner casing section and an internal surface of the outer casing section.

7. The fan assembly of claim 6 , wherein the outlet is in the form of a slot.

8. The fan assembly of claim 6 , wherein the outlet has a width in the range from 0.5 to 5 mm.

9. The fan assembly of claim 1 , wherein the remote control comprises a concave outer surface and the air outlet comprises a convex outer surface which faces the concave outer surface of the remote control when the remote control is attached to the air outlet by the magnetic means.

10. The fan assembly of claim 9 , wherein the concave outer surface of the remote control has a radius of curvature which is substantially the same as the radius of curvature of the convex outer surface of the air outlet.

11. The fan assembly of claim 9 , wherein the concave outer surface of the remote control comprises a user interface.

12. The fan assembly of claim 11 , wherein the remote control comprises at least one magnet located beneath the concave outer surface of the remote control.

13. The fan assembly of claim 9 , wherein the remote control comprises a convex outer surface located opposite to the concave outer surface.

14. The fan assembly of claim 13 , wherein the convex outer surface of the remote control has a radius of curvature which is substantially the same as the radius of curvature of the concave outer surface of the remote control.

15. The fan assembly of claim 1 , wherein said at least one magnet is arranged so that the force required to remove the remote control from the air outlet is less than 2 N.

16. The fan assembly of claim 1 , wherein said at least one magnet is arranged so that the force required to remove the remote control from the air outlet is less than 1 N.
