Abstract

A hair care appliance including a body, and a handle having a first end in fluid communication with the body and a second end comprising a primary fluid inlet into the appliance wherein the primary fluid inlet includes a first aperture extending at least partially around the handle and a second aperture extending through the second end of the handle. The handle can include an end wall that is substantially orthogonal to the handle at the second end with the second aperture extending through the end wall. The first aperture may be adjacent the second end. The handle may include a fan unit for drawing fluid into the primary fluid inlet upstream of the primary fluid inlet. The first aperture may include a plurality of apertures extending at least partially around and along the handle. The second aperture may include a plurality of apertures extending through the handle end.

First claim

The invention claimed is:

1. A hair care appliance comprising a body, and a handle having a first end in fluid communication with the body and a second end comprising a primary fluid inlet into the appliance wherein the primary fluid inlet comprises a first aperture extending at least partially around the handle and a second aperture extending through the second end of the handle, and wherein the handle comprises a first wall and a primary fluid flow path extends within the first wall and the handle comprises an outer wall that extends around the first wall and at least partially along the first wall.

2. The appliance of claim 1 , wherein the handle comprises an end wall at the second end and the second aperture extends through the end wall.

3. The appliance of claim 2 , wherein the end wall is substantially orthogonal to the handle.

4. The appliance of claim 1 , wherein the first aperture is adjacent the second end of the handle.

5. The appliance of claim 1 , wherein the handle includes a fan unit for drawing fluid into the primary fluid inlet.

6. The appliance of claim 5 , wherein the fan unit is upstream of the primary fluid inlet.

7. The appliance of claim 1 , wherein the first aperture comprises a plurality of apertures extending at least partially around the handle.

8. The appliance of claim 1 , wherein the first aperture comprises a plurality of apertures extending at least partially along the handle.

9. The appliance of claim 8 , wherein the plurality of apertures extend radially around the handle and along the outer wall of the handle from the second end.

10. The appliance of claim 1 , comprising a power cable for supplying power to the fan unit is provided, the power cable extending through the second end of the handle.

11. The appliance of claim 10 , wherein the power cable extends substantially centrally through the handle at the primary fluid inlet.

12. The appliance of claim 11 , wherein the second aperture extends at least partially around the power cable.

13. The appliance of claim 1 , wherein the primary fluid flow path extends from the primary fluid inlet through the handle and into the body to a primary fluid outlet.

14. The appliance of claim 1 , wherein the inner wall of the handle is connected to the body at the first end.

15. The appliance of claim 1 , wherein the handle comprises a layer of insulating material between the outer wall and the first wall.

16. The appliance of claim 13 , wherein the primary fluid outlet comprises a plurality of apertures extending at least partially along and around the body.

17. The appliance of claim 1 , wherein the primary fluid flow path is substantially linear through the handle and into the body.

18. The appliance of claim 1 , wherein the handle is substantially orthogonal to the body.

19. The appliance of claim 1 , wherein the body comprises a fluid flow path.

20. The appliance of claim 19 , wherein the fluid flow path is defined by a duct extending through the body.

21. A hair care appliance comprising a body, and a handle having a first end in fluid communication with the body and a second end comprising a primary fluid inlet into the appliance wherein the primary fluid inlet comprises a first aperture extending at least partially around the handle and a second aperture extending through the second end of the handle, and wherein the body comprises a fluid flow path and the fluid flow path is defined by a duct extending through the body.

22. The appliance of claim 19 , wherein the fluid flow path extends from a fluid inlet to a fluid outlet.

23. The appliance of claim 19 , wherein the body comprises a heater for heating fluid in the primary fluid flow path.

24. The appliance of claim 23 , wherein the heater extends around the duct.

25. The appliance of claim 23 , wherein the heater extends along the body.

26. The appliance of claim 23 , wherein the heater is annular.

27. The appliance of claim 19 , wherein within the body the primary fluid flow path surrounds the fluid flow path.

28. The appliance of claim 27 , wherein the primary fluid flow path merges with the fluid flow path within the body.

29. The appliance of claim 27 , wherein a primary fluid outlet extends about the fluid flow path.

30. The appliance of claim 28 , wherein a primary fluid outlet extends about a fluid outlet.

31. A hand held appliance comprising a body, and a handle having a first end in fluid communication with the body and a second end comprising a primary fluid inlet into the appliance, wherein the primary fluid inlet comprises a first aperture extending at least partially around the handle and a second aperture extending through the second end of the handle, and wherein the handle comprises a first wall and a primary fluid flow path extends within the first wall and the handle comprises an outer wall that extends around the first wall and at least partially along the first wall.
