Embodiment Construction

[0021] Referring to the drawings and, in particular, to FIG. 2, there is provided an embodiment of an electric heating unit for use as a hair curler / setter or for use in a hair styling device. Heating unit 200 includes a resistive heating conductive layer 205 sandwiched between an outer ceramic layer 210 and an inner ceramic layer 215, end gaps 220 and electrical leads 225. Electrical leads or wires 225 are electrically connected to conductive layer 205.

[0022] End gaps 220 are located at the ends of heating unit 200 due to an extension of outer ceramic layer 210 relative to conductive layer 205 and inner ceramic layer 215. In the embodiment shown in FIG. 2, outer ceramic layer 210 has a length along an axis 230 that is longer than a length along axis 230 of conductive layer 205 and inner ceramic layer 215.

[0023] In a preferred embodiment, end gaps 220 are filled with a thermally insulating adhesive material, such as an epoxy or a glue. The adhesive material contacts and bonds oute...

Abstract

There is provided a heating element for a hair styling device, including an electrically insulating inner ceramic layer, an electrically conductive resistive heating layer disposed on and in contact with the inner layer, and an electrically insulating outer ceramic layer disposed on and in contact with the resistive heating layer. There is also provided a method for manufacturing the heating element. There is further provided a hair setting device for curling hair including the heating element a cylindrical barrel surrounding the heating element.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application is claiming priority of Chinese Patent Application No. 200520133523.X, filed on Nov. 25, 2005, the content of which is herein incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to home appliances involving electric heating, and more particularly, to hair care appliances having heating elements. [0004] 2. Description of the Related Art [0005] Commonly used hair curlers or hair setters generally employ cylindrical heating elements that contact hair by wrapping hair around the heating element to achieve a desired curling effect. Typical hair curling systems may include a hand-held curling iron featuring a handle, a cylindrical heating element, and an attachment to clamp the hair in place about the heating element. Other systems include a plurality of individual heat rollers that are docked in a power-supply unit and heated prior to application...
