Patent ID: 8246317

Claim:
A fan assembly for creating an air current, the fan assembly comprising: a base having an air inlet and an air outlet, the base housing: an impeller, and a motor configured to rotate the impeller to create an air flow passing from the air inlet to the air outlet; and a vertically oriented, elongate annular nozzle comprising: an annular inner casing section and an annular outer casing section, an interior passage, formed between the annular inner casing and the annular outer casing, configured to receive the air flow from the base, a mouth configured to emit the air flow, the mouth comprising a slot-shaped outlet, and a plurality of guide vanes located within the interior passage, each of the guide vanes comprising a surface such that the air flow conveyed in a substantially vertical direction through the interior passage impinges upon the surfaces to guide the air flow in a substantially horizontal direction towards the mouth, the nozzle defining an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth.
