Abstract

A hand held appliance comprising a fluid flow path extending from a fluid inlet into the appliance to a fluid outlet from the appliance, the fluid flow path being at least partially defined by a wall, a switch mechanism housed by the wall having a cooperating externally accessible actuating button and a switch cover extending within the wall and containing the switch mechanism. The switch cover may maintain a spatial location of the switch mechanism relative to the actuating button. The switch cover may encase the switch mechanism. The switch cover may isolate the switch mechanism from the fluid flow path. The switch cover may maintain a spatial location of the switch mechanism relative to the wall. The switch cover may be curved towards an upstream end to reduce disturbance to the flow of fluid within the fluid flow path.

Claims (17)

1. A hand held appliance comprising:

a fluid flow path extending from a fluid inlet into the appliance to a fluid outlet from the appliance, the fluid flow path being at least partially defined by a wall, a switch mechanism housed between the wall and a switch cover that extends within the wall and covers the switch mechanism, the switch mechanism having a cooperating externally accessible actuating button,

wherein the wall has an inner surface and an outer surface, the fluid flow path being at least partly defined by the inner surface of the wall, wherein the inner surface of the wall comprises a lip which extends from the inner surface and engages with the switch cover to define a location of the switch cover with respect to the wall.

2. The appliance of claim 1 , wherein the switch cover maintains a spatial location of the switch mechanism relative to the actuating button.

3. The appliance of claim 1 , wherein the switch cover encases the switch mechanism.

4. The appliance of claim 3 , wherein the switch cover isolates the switch mechanism from the fluid flow path.

5. The appliance of claim 1 , wherein the switch cover maintains a spatial location of the switch mechanism relative to the wall.

6. The appliance of claim 1 , wherein an upstream end of the switch cover is curved to reduce disturbance to the flow of fluid within the fluid flow path.

7. The appliance of claim 1 , wherein the lip engages with the switch mechanism to define a location of the switch mechanism with respect to the wall.

8. The appliance of claim 1 , wherein the lip forms a part of a labyrinth seal around the switch mechanism.

9. The appliance of claim 8 , wherein the switch cover forms another part of a labyrinth seal around the switch mechanism.

10. The appliance of claim 1 , wherein the switch mechanism includes an activation knob which cooperates with the externally accessible actuating button.

11. The appliance of claim 1 , wherein the switch cover additionally houses a second switch.

12. The appliance of claim 1 , wherein the appliance is a hair care appliance.

13. The appliance of claim 12 , wherein the hair care appliance is a hairdryer.

14. The appliance of claim 1 , wherein the switch cover at least partially covers at least one wire connected to the switch mechanism.

15. The appliance of claim 1 , wherein the switch mechanism is housed in a cavity formed at least partially by the wall and the switch cover.
