Abstract

A fan assembly includes a nozzle having a first casing section, a second casing section, an air inlet, an air outlet, and an interior passage for conveying air from the air inlet to the air outlet. The nozzle defines a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle. The nozzle is detachably mounted on a body including a motor and impeller unit for generating an air flow through the interior passage, and a humidifier for humidifying the air flow before it enters the interior passage. The first casing section defines, at least in part, the interior passage, and is detachable from the second casing section to allow the interior passage to be accessed by a user for cleaning.

First claim

The invention claimed is:

1. A fan assembly comprising:
a nozzle having a first casing section with a first base comprising at least one first air inlet, a second casing section with a second base comprising at least one second air inlet, at least one air outlet, and an interior passage for conveying air from said at least one first air inlet or said at least one second air inlet to said at least one air outlet, the nozzle defining a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle, wherein one of the first casing section and the second casing section comprises a plurality of catches spaced about the bore and the other one of the first casing section and the second casing section comprises a plurality of recesses similarly spaced about the bore for receiving the plurality of catches and wherein the first casing section forms the front of the nozzle and is in front of the second casing section and the front of the nozzle is a portion of the nozzle that is the most downstream from the air flow emitted from the at least one air outlet; and
a body on which the nozzle is detachably mounted such that the first base and second base are inserted in the body when the nozzle is mounted on the body, the body comprising a flow generating device for generating an air flow through the interior passage, and a humidifying system for humidifying the air flow before it enters the interior passage;
wherein the first casing section is detachable from the second casing section, the first casing section defining, at least in part, the interior passage.

2. The fan assembly of claim 1 , wherein the first casing section is arranged to define, at least in part, said at least one air outlet.

3. The fan assembly of claim 1 , wherein the first casing section is annular in shape.

4. The fan assembly of claim 1 , wherein both of the first and second casing sections define said bore.

5. The fan assembly of claim 1 , wherein said at least one air outlet is arranged to emit air over at least part of the first casing section.

6. The fan assembly of claim 1 , wherein the first casing section is detachably attached to the second casing section by a snap-fit connection.

7. The fan assembly of claim 1 , wherein the second casing section defines with the first casing section said at least one air outlet.

8. The fan assembly of claim 1 , wherein the body comprises a water tank and the first base is inserted into a portion of the water tank when the nozzle is mounted on the body.

9. A fan assembly comprising:
a nozzle having a first section comprising a first casing section with a first base comprising at least one first air inlet, at least one first air outlet, and a first interior passage for conveying air from said at least one first air inlet to said at least one first air outlet; and a second section having 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, at least one of the first and second sections of the nozzle defining a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle; and
a body on which the nozzle is mounted, the body comprising a flow generating device 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;
wherein the second section of the nozzle comprises a second casing section with a second base comprising the at least one second air inlet and defining, at least in part, the second interior passage, wherein one of the first casing section and the second casing section comprises a plurality of catches spaced about the bore and the other one of the first casing section and the second casing section comprises a plurality of recesses similarly spaced about the bore for receiving the plurality of catches, and wherein the first base and second base are inserted in the body when the nozzle is mounted on the body and wherein the first casing section forms the front of the nozzle and is in front of the second casing section and the front of the nozzle is a portion of the nozzle that is the most downstream from the air flow emitted from the at least one first air outlet and the at least one second air outlet.

10. The fan assembly of claim 9 , wherein the second casing section comprises said at least one second air inlet.

11. The fan assembly of claim 9 , wherein the second casing section is annular in shape.

12. The fan assembly of claim 9 , wherein both of the first and second sections of the nozzle define said bore.

13. The fan assembly of claim 9 , wherein each of said at least one first air outlet and said at least one second air outlet is arranged to emit air over at least part of the second casing section.

14. The fan assembly of claim 9 , wherein the nozzle comprises the second casing section which defines with the second casing section the second interior passage, and wherein the second casing section is detachably attached to the second casing section.

15. The fan assembly of claim 14 , wherein the first casing section is detachably attached to the second casing section by a snap-fit connection.

16. The fan assembly of claim 14 , wherein the second casing section defines with the first casing section said at least one second air outlet.

17. The fan assembly of claim 14 , wherein the second casing section defines, at least in part, the first interior passage.

18. The fan assembly of claim 17 , wherein the second casing section defines, at least in part, said at least one first air outlet.

19. The fan assembly of claim 14 , wherein the nozzle comprises a diffuser located downstream from said at least one first air outlet, and wherein the second casing section comprises a first portion of the diffuser and the first casing section comprises a second portion of the diffuser.

20. The fan assembly of claim 19 , wherein said at least one second air outlet is located between the first portion of the diffuser and the second portion of the diffuser.

21. The fan assembly of claim 14 , wherein the nozzle is detachable from the body, and wherein the first casing section is detachable from the second casing section only when the nozzle is detached from the body.

22. The fan assembly of claim 14 , wherein the first base is graspable by a user to detach the first casing section from the second casing section.

23. The fan assembly of claim 9 , wherein the body comprises a water tank and the first base is inserted into a portion of the water tank when the nozzle is mounted on the body.

24. A fan assembly comprising:
a nozzle having a first casing section with a first base comprising at least one first air inlet, a second casing section with a second base comprising at least one second air inlet, at least one air outlet, and an interior passage for conveying air from said at least one first air inlet or said at least one second air inlet to said at least one air outlet, the nozzle defining a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle, wherein one of the first casing section and the second casing section comprises a plurality of catches spaced about the bore and the other one of the first casing section and the second casing section comprises a p
