Abstract

A mount for an electric motor, the mount including a sleeve for receiving the motor, the sleeve including an annular seal extending around the sleeve and a recess extending around the circumference of the sleeve. The sleeve has a first end and a second end. The recess may be disposed adjacent the first end of the sleeve. The annular seal may be disposed at the first end and the recess next to the annular seal. The first end may be a downstream end of the mount. The recess may be an indentation extending circumferentially around sleeve. The recess may be provided on a radially outer surface of the sleeve. The recess may comprise first and second radial surfaces which are spaced apart when in an uncompressed state. The first and second surfaces are pressed together when in a compressed state.

Claims

1. A mount for an electric motor, the mount comprising a sleeve for receiving a motor, the sleeve including an annular seal and a recess extending around the circumference of the sleeve, wherein the mount includes a first set of compression ribs disposed on an internal surface of the sleeve, wherein the mount includes a second set of compression ribs disposed on an external surface of the sleeve, and wherein the first set and second set of compression ribs are located on opposite ends of the sleeve.

2. The mount of claim 1, wherein the sleeve has a first end and a second end.

3. The mount of claim 2, wherein the recess is disposed adjacent the first end of the sleeve.

4. The mount of claim 3, wherein the annular seal is disposed at the first end and the recess is next to the annular seal.

5. The mount of claim 3, wherein the first end is a downstream end of the mount.

6. The mount of claim 1, wherein the recess is an indentation extending circumferentially around the sleeve.

7. The mount of claim 1, wherein the recess is provided on a radially outer surface of the sleeve.

8. The mount of claim 1, wherein the recess comprises first and second radial surfaces which are spaced apart when in an uncompressed state.

9. The mount of claim 8, wherein the first and second surfaces are pressed together when in a compressed state.

10. A hair care appliance comprising:

a casing having a fluid inlet, a fluid outlet and an annular seat; and

the mount for an electric motor of claim 1 wherein the mount is supported by the annular seat.

11. A hair care appliance comprising:

a casing having a fluid inlet, a fluid outlet and an annular seat;

a mount for an electric motor supported by the annular seat, the motor mount comprising;

a sleeve for receiving a motor, the sleeve including an annular seal extending around the sleeve in sealing engagement with the annular seat and a recess extending around the circumference of the sleeve, wherein the mount includes a first set of compression ribs disposed on an internal surface of the sleeve, wherein the mount includes a second set of compression ribs disposed on an external surface of the sleeve, and wherein the first set and second set of compression ribs are located on opposite ends of the sleeve.

12. The appliance of claim 11, wherein the appliance comprises a body which houses a heater and a handle which includes the casing.

13. The appliance of claim 11, wherein the appliance comprises a fluid flow path extending from a fluid inlet into the casing to a fluid outlet in the body.

14. The appliance of claim 11, wherein the recess is provided at a downstream end of the motor mount.
