Abstract
A fan assembly includes a motor-driven impeller for creating an air flow, a casing including an interior passage for receiving the air flow, and a plurality of air outlets for emitting the air flow from the casing. The casing defines and extends about an opening through which air from outside the casing is drawn by the air flow emitted from the air outlets. The fan assembly also includes at least one heater for heating at least a first portion of the air flow, and means for diverting at least a second portion of the air flow away from said at least one heater. The plurality of outlets includes at least one first air outlet for emitting the relatively hot first portion of the air flow and at least one second air outlet for emitting the relatively cold second portion of the air flow.
Claims55
A fan assembly comprising a nozzle for creating an air current, the nozzle comprising:
- an interior passage for receiving an air flow, and for dividing a received air flow into a plurality of air streams;
- and
- a plurality of air outlets for emitting the air flow from the nozzle, the nozzle defining an opening through which air from outside the nozzle is drawn by the air flow emitted from the air outlets;
- wherein the interior passage extends around the opening, and houses a heating arrangement for heating a first portion of each air stream and at least one air diverting surface for diverting a second portion of each air stream away from the heating arrangement;
- and the plurality of air outlets comprises at least one first air outlet for emitting the first portions of the air streams, and at least one second air outlet for emitting the second portions of the air streams,
- wherein the heating arrangement comprises a plurality of heater assemblies each for heating a respective first portion of the air flow, and
- wherein said at least one air diverting surface comprises a plurality of walls located within the interior passage each for diverting a respective second portion of the air flow away from a heater assembly.
A fan assembly comprising a nozzle for creating an air current, the nozzle comprising:
- an interior passage for receiving an air flow, and for dividing a received air flow into a plurality of air streams;
- and
- a plurality of air outlets for emitting the air flow from the nozzle, the nozzle defining an opening through which air from outside the nozzle is drawn by the air flow emitted from the air outlets;
- wherein the interior passage extends around the opening, and houses a heating arrangement for heating a first portion of each air stream and at least one air diverting surface for diverting a second portion of each air stream away from the heating arrangement;
- and the plurality of air outlets comprises at least one first air outlet for emitting the first portions of the air streams, and at least one second air outlet for emitting the second portions of the air streams,
- wherein the interior passage comprises, for each air stream, a first channel for conveying the first portion of the air stream to one of the plurality of air outlets, a second channel for conveying the second portion of the air stream to another one of the plurality of air outlets, and a wall for separating the first channel from the second channel, and
- wherein each of the first channel and the second channel is shaped so as substantially to reverse the flow direction of a respective portion of the air stream.
A fan assembly comprising a nozzle for creating an air current, the nozzle comprising:
- an interior passage for receiving an air flow, and for dividing a received air flow into a plurality of air streams;
- and
- a plurality of air outlets for emitting the air flow from the nozzle, the nozzle defining an opening through which air from outside the nozzle is drawn by the air flow emitted from the air outlets;
- wherein the interior passage extends around the opening, and houses a heating arrangement for heating a first portion of each air stream, at least one first air diverting surface for diverting a second portion of each air stream away from the heating arrangement and at least one second air diverting surface for diverting a third portion of each air stream away from the heating arrangement;
- and the plurality of air outlets comprises at least one first air outlet for emitting the first portions of the air streams, and at least one second air outlet for emitting the second portions of the air streams,
- wherein the interior passage comprises, for each air stream, a first channel for conveying the first portion of the air stream to one of the plurality of air outlets, a second channel for conveying the second portion of the air stream to another one of the plurality of air outlets, a wall for separating the first channel from the second channel, and a third channel for conveying the third portion of the air stream along an internal surface of one of the casing sections.
