Abstract

An air moving device includes a housing member, a rotary fan assembly, and a nozzle, the housing including a plurality of air vents. The air moving device further includes at least one anti-drip structure in the form of a peripheral lip member for inhibiting water from entering the air moving device. The air moving device further includes a baffle member that acts to redirect a volume of air that enters through the plurality of air vents.

Claims

1. An air moving device comprising:

a housing member forming an interior space within the air moving device, the housing member comprising a plurality of air intake openings for directing a volume of air into the interior space;

a lip member integrally formed with or attached to the housing member, the lip member forming an outer peripheral edge of the air moving device, the lip member flared outwardly away from the housing member so as to form a drip edge along the housing member, the portion of the housing member above the lip member defining a surface which has no through opening;

a rotary fan assembly mounted within the interior space, the rotary fan assembly comprising an impeller and a plurality of blades for further directing the volume of air; and

a nozzle communicating with and extending downwardly from the rotary fan assembly, the nozzle comprising a structure for further directing the volume of air out of the air moving device, wherein the plurality of air intake openings is located circumferentially inward from the outer peripheral edge of the air moving device.

2. The air moving device of claim 1, wherein housing member comprises an upper housing member, the upper housing member forming a generally solid, dome-shaped structure.

3. The air moving device of claim 1, wherein the nozzle comprises at least one stator vane.

4. The air moving device of claim 1, wherein the housing member comprises at least one anti-swirl member.

5. The air moving device of claim 1, wherein the air moving device further comprises a baffle member disposed within the interior space, the baffle member configured to redirect the volume of air entering the plurality of air intake openings.

6. The air moving device of claim 1, wherein the air moving device comprises a longitudinal axis, the housing member comprises an opening for insertion of the nozzle, and the nozzle comprises at least one spherical surface configured to fit within the opening such that the nozzle can be adjusted angularly relative to the longitudinal axis.

7. The air moving device of claim 1, wherein the housing member comprises an upper housing member and a lower housing member, the upper housing member connected to the lower housing member.

8. The air moving device of claim 7, wherein the rotary fan is mounted to the lower housing member.

9. The air moving device of claim 7, wherein the lip member forms part of the upper housing member.

10. The air moving device of claim 9, wherein the lip member comprises an outwardly flared lower portion of the upper housing member.

11. The air moving device of claim 7, wherein the upper housing member comprises a first outer diameter, and the lower housing member comprises a second outer diameter, the first outer diameter being greater than the second outer diameter.

12. An air moving device comprising:

a housing member forming an interior space within the air moving device, the housing member comprising a plurality of air intake openings for directing a volume of air into the interior space of the air moving device;

a baffle member disposed at least partially within the interior space of the air moving device, the baffle member positioned at least partially circumferentially inward from the plurality of air intake openings and connected to the housing member and configured to redirect the volume air within the interior space;

a rotary fan assembly mounted in the interior space, the rotary fan assembly comprising an impeller, a plurality of blades, and an open upper end, the rotary fan assembly configured to further redirect the volume of air within the interior space; and

a nozzle communicating with and extending downwardly from the rotary fan assembly, the nozzle comprising a structure for further directing the volume of air out of the air moving device, wherein the baffle member extends below the open upper end of the fan assembly.

13. The air moving device of claim 12, further comprising a lip member integrally formed with or attached to the housing member, the lip member forming an outer peripheral edge of the air moving device, the lip member flared outwardly away from the housing member so as to form a drip edge along the housing member, the portion of the housing member above the lip member defining a surface which has no through opening.

14. The air moving device of claim 12, wherein the nozzle comprises at least one stator vane.

15. The air moving device of claim 12, wherein the housing member comprises at least one rib member located within the interior space.

16. The air moving device of claim 12, wherein the air moving device comprises a longitudinal axis, the housing member comprises an opening for insertion of the nozzle, and the nozzle comprises at least one spherical surface configured to fit within the opening such that the nozzle can be adjusted angularly relative to the longitudinal axis.

17. The air moving device of claim 12, wherein the housing member comprises an upper housing member and a lower housing member, the upper housing member connected to the lower housing member.

18. The air moving device of claim 17, wherein the rotary fan is mounted to the lower housing member.

19. The air moving device of claim 18, wherein the lip member forms part of the upper housing member.

20. The air moving device of claim 19, wherein the lip member comprises an outwardly flared lower portion of the upper housing member.
