Abstract

A fan assembly includes a nozzle and a body on which the nozzle is mounted. The nozzle has a rear section having at least one first air inlet, at least one first air outlet, and a first interior passage for conveying air from the at least one first air inlet to the at least one first air outlet; and a front section having at least one second air inlet, at least one second air outlet, and a second interior passage for conveying air from the at least one second air inlet to the at least one second air outlet. A first air flow through the first interior passage and a second air flow through the second interior passage are each generated within the body. At least one of the temperature, humidity, and electrical charge of the second air flow is changed before it enters the second interior passage.

Claims

1. (canceled)

6. The humidifying apparatus of claim 1, wherein said at least one first air outlet is arranged to emit the first air flow through at least a front part of the bore.

7. The humidifying apparatus of claim 6, wherein said at least one first air outlet is arranged to emit the first air flow over a surface defining the front part of the bore.

8. The humidifying apparatus of claim 1, wherein the body comprises a first air passageway for conveying the first air flow to said at least one first air inlet of the nozzle, and a second air passageway for conveying the second air flow to said at least one second air inlet of the nozzle.

9. The humidifying apparatus of claim 8, wherein the body comprises an air flow inlet for admitting at least the first air flow into the humidifying apparatus from outside the body.

10. The humidifying apparatus of claim 9, wherein the air flow inlet comprises a plurality of apertures.

11. The humidifying apparatus of claim 8, wherein the second air passageway is arranged to receive air from the first air passageway.

12. The humidifying apparatus of claim 1, wherein the air flow generating system comprises an impeller and a motor for driving the impeller.

13. The humidifying apparatus of claim 1, wherein the first interior passage is isolated from the second interior passage.

14. The humidifying apparatus of claim 1, wherein the humidifying system comprises a water reservoir and a transducer for atomizing water in the water reservoir.

15. The humidifying apparatus of claim 14, wherein the body comprises a water tank for supplying water to the water reservoir.

16. The humidifying apparatus of claim 15, wherein the body comprises a base housing said air flow generating system, and wherein the water tank is mounted on the base.

2. A humidifying apparatus comprising:

a nozzle having at least one first air inlet, at least one first air outlet, a first interior passage for conveying air from said at least one first air inlet to said at least one first air outlet, at least one second air inlet, at least one second air outlet, and a second interior passage for conveying air from said at least one second air inlet to said at least one second air outlet, the nozzle defining a bore through which air from outside the humidifying apparatus is drawn by air emitted from the nozzle; and

a body on which the nozzle is mounted, the body comprising an air flow generating system for generating a first air flow through the first interior passage and a second air flow through the second interior passage, and a humidifying system for humidifying the second air flow before it enters the second interior passage.

3. The humidifying apparatus of claim 2, wherein said at least one first air outlet is located behind said at least one second air outlet.

4. The humidifying apparatus of claim 3, wherein said at least one first air outlet of the nozzle comprises an air outlet which extends about the bore of the nozzle.

5. The humidifying apparatus of claim 4, wherein said air outlet is continuous.
