Description
- This application claims the benefit of U.S. provisional application No. 61/776,435, filed Mar. 11, 2013, the contents of which are herein incorporated by reference.
- The present invention relates to ceiling fans and, more particularly, to a ceiling fan enclosed within multiple hoods combined to create a quieter, aerodynamic flow.
- There are multiple problems with existing ceiling fans, including the unpleasant feeling of a stream of air in people's face and throat, and the safety hazard of having spinning blades exposed in a room.
- Every fan in the market is exposed in the room, with no enclosure or aerodynamic surface to modify the flow. Additionally, the selection of a wing profile used for most fans in the market is based on manufacture economics, and aerodynamics is usually overlooked, causing a significant decrease in efficiency.
- As can be seen, there is a need for a ceiling fan with the fan blades enclosed, and that provides an aerodynamically efficient shape.
- In one aspect of the present invention, a ceiling fan system comprises: a motor/blade assembly comprising: a motor; a main rotor attached to the motor; and a plurality of blades attached to the main rotor; and a plurality of hoods partially enclosing the motor/blade assembly.
- In another aspect of the present invention, a method for producing quiet flow of air comprises: attaching a ceiling fan system to a surface, wherein the ceiling fan system is defined by a motor/blade assembly comprising a motor; a main rotor attached to the motor; and a plurality of blades attached to the main rotor; an intake nozzle hood positioned around and above the motor/blade assembly; an outlet surface hood attached to a lower end of the inlet nozzle hood; a down rod attached to the motor, wherein the down rod secures the weight of the motor/blade assembly; and a canopy enclosing the down rod; and controlling the ceiling fan system.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
-
FIG. 1 is a perspective view of an exemplary embodiment of the present invention; -
FIG. 2 is an exploded view of an exemplary embodiment of the present invention; -
FIG. 3 is a section view of an exemplary embodiment of the present invention taken along line 3-3 inFIG. 1 ; -
FIG. 4 is a detail section view of an exemplary embodiment of the present invention; and -
FIG. 5 is a front view of an exemplary embodiment of the present invention, illustrating the movement of the air between an intake nozzle hood and an outlet surface hood. - The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention.

Thehanger bracket 17 may also be attached to adown rod 18. Thedown rod 18 may fit into adown rod slot 60. Amounting bracket tab 62 may help secure thedown rod 18 in place. In certain embodiments, thedown rod 18 may be made from metal and may have adown rod tip 20 that may enclose thedown rod 18. Thedown rod 18 may hold theceiling fan system 10 in place. Thedown rod 18 may be positioned inside the hangingbracket 17. Wiring may be connected to the grid and hidden within acanopy 16. Thecanopy 16 may be mounted to theceiling 68 with acanopy mount bar 15. Thecanopy 16 mounting may include a plurality ofcanopy mounting screws 54. Ajunction box 64 placed within the ceiling may be secured to thehanger bracket 17 byjunction box screws 66 or the like. - An
