Abstract

Resistance heating element 1 for a hair styling device comprises a resistance heating wire arrangement held by a support body 2, and a layer 4 which covers and electrically insulates the heating wire. The resistance heating wire arrangement has at least one heating wire 3. The support body 2 is formed solely by a shape-stable hollow body consisting of an electrically insulating and heat resistant flexible material, and the outside of the resistance heating element 1 is formed by a layer covering the heating wire 3.

Claims

1-10. -10. (canceled)

11. A resistance heating element for a hair styling device comprising:

at least one heating wire held by a support body and a layer which covers and electrically insulates the at least one heating wire;

wherein the support body is formed from a shape-stable hollow body consisting of an electrically insulating and heat resistant flexible material; and

an outer surface of the resistance heating element is formed by the layer covering the heating wire.

12. The resistance heating element of claim 11, wherein the support body is an annular body, especially an annular cylinder.

13. The resistance heating element as claimed in claim 11 or 12, wherein the electrically insulating and heat resistant material of the support body and the layer covering heating wire is a mineral based material.

14. The resistance heating element as claimed in claim 11 or 12, wherein electrical leads for making contact with the heating wire are arranged on an interior of the support body.

15. The resistance heating element as claimed in claim 13, wherein electrical leads for making contact with the heating wire are arranged on an interior of the support body.

16. The resistance heating element as claimed in claim 11 or 12, wherein the resistance heating element is associated with a thermal fuse arranged on an interior of the support body.

17. The resistance heating element as claimed in claim 13, wherein the resistance heating element is associated with a thermal fuse arranged on an interior of the support body.

18. The resistance heating element as claimed in claim 11 or 12, wherein a temperature sensor is arranged on the outer surface of the resistance heating element with electrical connection contacts of the temperature sensor lying inside the support body.

19. The resistance heating as claimed in claim 11 or 12, wherein the outer surface of the resistance heating element is arranged in almost direct contact with a tubular tool being heated, with the interpositioning of at least one foil layer serving as electrical insulation.

20. The resistance heating as claimed in claims 13, wherein the outer surface of the resistance heating element is arranged in substantially direct contact with a tubular tool being heated, with the interpositioning of at least one foil layer serving as electrical insulation.

21. The resistance heating as claimed in claims 14, wherein the outer surface of the resistance heating element is arranged in substantially direct contact with a tubular tool being heated, with the interpositioning of at least one foil layer serving as electrical insulation.

22. The resistance heating element as claimed in claim 21, wherein one or more layers of a polyimide foil are arranged between the outer surface of the resistance heating element and the surface of the tool being heated, for the electrical insulation of the resistance heating element relative to the tool being heated.

23. The resistance heating as claimed in claim 11 or 12 further comprising:

a hair styling appliance with a heated hair styling tool wherein the hair styling tool comprises a tube having an outer lateral surface for use in a hair styling process; and

wherein one or more resistance heating elements are arranged in the tube.

24. The resistance heating element of claim 23, wherein the hair styling appliance is a curling iron.
