Abstract:
1. A vertical tower fan that is portable and free standing on a support surface, said vertical tower fan comprising: an air blower assembly comprising; a vertically oriented elongate housing having at least one sidewall having a longitudinal length extending substantially upward from said support surface; an interior space defined by said elongate housing, said air blower assembly being disposed within said interior space; at least one air inlet in said at least one sidewall allowing intake air to enter said interior space; an air guide disposed within said interior space; an exhaust air stream generated by said air blower assembly, wherein said exhaust air stream comprises a maximum velocity in the range of about 150 feet per minute to about 450 feet per minute at a distance of about 8 feet from the vertical tower fan, wherein said exhaust air stream also comprises a maximum exit elevation greater than about 36 inches, said maximum exit elevation defined by a distance from said support surface to a highest exit elevation of said exhaust air stream, and wherein the velocity of said exhaust air stream, the maximum exit elevation of said exhaust air stream, and the axial length of said air impeller enable said exhaust air stream to deliver a desired cooling effect at a predetermined distance from the vertical tower fan; an elongate air outlet located in said at least one sidewall allowing said exhaust air stream to exit said interior space above said support surface; an air cut-off disposed within said interior space; a base of said elongate housing for engaging said support surface; and an overall height of said device being defined as the distance from where said base engages said support surface to a maximum vertical extent of said device, wherein said overall height of said device is greater than about 44 inches.
