The fan assembly further includes a vertically oriented, elongate annular nozzle including an interior passage having an air inlet for receiving the air flow from the base and a mouth for emitting the air flow, the nozzle defining an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth.
Claims16
A portable tower fan comprising an impeller located within an impeller housing, a motor for rotating the impeller to create an air flow which is exhausted from the impeller housing in a substantially vertical direction, and a vertically oriented, elongate casing comprising an interior passage for receiving the air flow, a mouth shaped to emit the air flow, and an opening through which air from outside the fan is drawn by the air flow emitted from the mouth, wherein a plurality of sealing members are located within the mouth to inhibit the emission of air form respective sections of the interior passage and to define a plurality of spaced apart outlets therebetween, and wherein each outlet is located along a respective elongate side of the casing.
