Abstract

Humidifying apparatus includes a base housing an impeller and a motor for driving the impeller to generate a first air flow. A nozzle includes an interior passage for receiving the first air flow and an air outlet for emitting the first air flow. The nozzle defines an opening through which air from outside the apparatus is drawn by air emitted from the air outlet. The apparatus is configured to humidify a second air flow, which is emitted from a plurality of second air outlets. The second air flow is humidified with water supplied from a water tank mounted on the base. The water tank has an upwardly curved upper surface. The nozzle is mounted on the apparatus so that the upper surface of the water tank at least partially covers a lower section of an external surface of the nozzle.

Claims

1. A humidifying apparatus comprising:

a base comprising an air flow generating device for generating a first air flow and an upper cylindrical section for conveying the first air flow to a nozzle;

the nozzle comprising a first nozzle base comprising at least one first air inlet for receiving the first air flow, at least one first air outlet for emitting the first air flow, a second nozzle base comprising at least one second air inlet for receiving a second air flow, and at least one second air outlet for emitting the second air flow, the nozzle defining an opening through which air from outside the humidifying apparatus is drawn by air emitted from said at least one first air outlet, wherein the at least one first air outlet and the at least one second air outlet extend at least partially about the opening;

a water tank comprising an outlet duct for conveying the second air flow to the at least one second air inlet; and

a humidifying system for humidifying the second air flow,

wherein the water tank is mounted on the base to form a body and the nozzle is mounted on the body such that the first nozzle base is inserted into the upper cylindrical section of the base and the second nozzle base is inserted into the outlet duct of the water tank.

2. The apparatus of claim 1, wherein the nozzle is removably mounted on the base.

3. The apparatus of claim 2, wherein the water tank comprises a lower surface locatable on the base, and wherein the lower surface comprises a water inlet of the water tank.

4. The apparatus of claim 1, wherein the upper surface of the water tank comprises at least one support for supporting the water tank on a work surface.

5. The apparatus of claim 4, wherein a periphery of the upper surface of the water tank comprises said at least one support.

6. The apparatus of claim 5, wherein said at least one support comprises parallel supports located on opposite sides of the water tank.

7. The apparatus of claim 1, comprising an air passageway for conveying the first air flow to the nozzle, and wherein the water tank comprises an inner wall which extends about the air passageway.

8. The apparatus of claim 7, wherein the base comprises a duct for conveying the first air flow to the nozzle, and wherein the inner wall of the water tank extends about the duct.

9. The apparatus of claim 1, wherein the humidifying system comprises a water reservoir for receiving water from the water tank and an atomizing device for atomizing water in the reservoir to humidify the second air flow, and wherein the base comprises the water reservoir and the atomizing device.

10. The apparatus of claim 1, wherein the nozzle comprises a first interior passage for conveying the first air flow to the at least one first air outlet and a second interior passage for conveying the second air flow air to the at least one second air outlet.

11. The apparatus of claim 10, wherein the first interior passage is isolated from the second interior passage.

12. The apparatus of claim 10, wherein the first interior passage surrounds the bore of the nozzle.

13. The apparatus of claim 10, wherein the second interior passage surrounds the bore of the nozzle.

14. The 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 of the nozzle.
