Benefits of technology
The patent describes a fan grill that can create a cone-shaped or vortex air flow to improve air circulation in a room. The grill is designed to increase air flow by spreading out the air currents across the fans' propellers and creating air flows at both higher and lower levels than the fans' elevation. The fan can also rotate the grill in a perpendicular direction to the air flow direction.
Problems solved by technology
However, these oscillating fans are not entirely effective at filling a room with circulating air, for several reasons.
First, it takes some amount of time for the fan to oscillate the propellers in different directions.
Second, because the air flow produced by the fan is limited to a generally cylindrical-shape, at any period of time the fan is only capable of blowing air in the direction that the propellers are facing (even given that the fan may oscillate).
Third, because the air flow produced by the fan is limited to a generally cylindrical-shape, the fan will not offer air current in regions that are located above or below the approximate elevation of the fan propellers, even if the fan does oscillate.

Abstract
A method and an apparatus for a fan grill, and a fan utilizing the fan grill, that produces a multi-directional air current. The fan grill includes a frame, and a first subset of one or more louvers with major surfaces that are angled to be about perpendicular to a horizontal plane of the fan grill frame. The fan grill also includes a second subset of one or more louvers with major surfaces that are angled to deviate from the first subset of louvers at an offset angle. The fan grill, and the fan utilizing the grill, is capable of producing an air current in a cone or vortex-shape in order to significantly increase air flow in a room. The fan may rotate the fan grill on an axis that is collinear with an axis of rotation of the propellers of the fan.
Description
PRIORITY STATEMENT[0001]This application is a non-provisional application that claims priority to U.S. Provisional Application No. 62 / 010,236, filed on Jun. 10, 2014, the entire contents of which is incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Example embodiments relate generally to a fan grill (and a fan utilizing the fan grill) able to produce a multi-directional air current. More particularly, example embodiments relate to a method and apparatus for a fan grill (and a fan utilizing the fan grill) able to produce a cone or a vortex-shaped air current.[0004]2. Related Art[0005]As shown in FIG. 1, conventional fans generally produce a cylindrically-shaped flow of air. Such a conventional fan may also spread air throughout a room by being able to oscillate the propellers of a fan on an axis. However, these oscillating fans are not entirely effective at filling a room with circulating air, for several reasons. First, it take...
