Abstract

A hand held appliance including a body, a handle, a fluid flow path flowing from a fluid inlet into the handle to a fluid outlet from the body and a baffle wherein the fluid flow path is non-linear and the baffle directs flow within the fluid flow path. The fluid flow path may flow in a first direction within the handle and a second direction within the body. The baffle may be provided to direct flow between the handle and the body. The baffle may extend from the handle into a space defined within the body. The handle may include a wall that defines the fluid flow path within the handle. The baffle may form a partial continuation of the wall. The body and the handle may be molded as a first part and a second part. The baffle may be formed from a handle part and a body part.

First claim

The invention claimed is:

1. A hair care appliance comprising: a body having a first end and a second end that is opposite the first end, a handle comprising a wall that extends in a longitudinal direction of the handle, a fluid flow path flowing from a fluid inlet into the handle to a fluid outlet from the second end of the body, and a baffle, wherein the fluid flow path is non-linear, the baffle directs flow within the non-linear fluid flow path between the handle and the body, and the baffle extends in the longitudinal direction from an end of the wall forming a partial continuation of the wall to at least partially block fluid in the fluid flow path from flowing toward the first end of the body.

2. The appliance of claim 1 , wherein the fluid flow path flows in a first direction within the handle and a second direction within the body.

3. The appliance of claim 1 , wherein the wall defines the fluid flow path within the handle.

4. The appliance of claim 1 , wherein the body and the handle are moulded as a first part and a second part.

5. The appliance of claim 4 , wherein the body comprises an outer wall and each of the outer wall of the body and the wall of the handle at least partially define the fluid flow path from the fluid inlet to the fluid outlet.

6. The appliance of claim 5 , wherein the first part of the appliance comprises a first portion of the wall of the handle.

7. The appliance of claim 6 , wherein the second part of the appliance comprises the outer wall of the body and a second portion of the wall of the handle.

8. The appliance of claim 7 , wherein when the first part and the second part are assembled a complete handle wall is produced.

9. The appliance of claim 5 , wherein the handle wall is located upstream of the fluid inlet.

10. The appliance of claim 5 , wherein the handle comprises an outer wall that surrounds the wall and includes the fluid inlet.

11. The appliance of claim 1 , wherein the fluid flow path in the body is substantially orthogonal to the fluid flow path in the handle.

12. The appliance of claim 11 , wherein first end of the body is an upstream end and the second end of the body is a downstream end.

13. The appliance of claim 12 , wherein the handle is located towards the upstream end of the body.

14. The appliance of claim 13 , wherein a printed circuit board (PCB) is provided within the body between the handle and the upstream end of the body.

15. A hand held appliance comprising: a body having a first end and a second end that is opposite the first end, a handle comprising a wall that extends in a longitudinal direction of the handle, a fluid flow path flowing from a fluid inlet into the handle to a fluid outlet from the second end of the body, and a baffle, wherein the fluid flow path is non-linear, the baffle directs flow within the fluid flow path, and the baffle extends in the longitudinal direction from an end of the wall forming a partial continuation of the wall to at least partially block fluid in the fluid flow path from flowing toward the first end of the body.
