Embodiment Construction

[0030] figure 1 A cross-section of a heating element 1 according to the invention is shown. The heating element 1 comprises a heating plate 2 made of ferritic chromium steel with a chromium content of 18% by weight for heating. Another suitable metal or ceramic carrier can also be applied, such as mild steel, copper, titanium, SiN, Al 2 o 3 etc. A first dielectric enamel layer 3 is arranged on the heating plate 2 . The first enamel layer 3 has an enamel composition substantially according to column HT of Table 1 . The heating tracks 4 and the sensor tracks 5 running parallel to the heating tracks 4 are arranged in an essentially spiral pattern on the first, relatively electrically insulating enamel layer 3 , wherein the distance between these tracks amounts to approximately 500 μm. Preferably, the heating track 4 and the sensor track 5 are made of the same material, more preferably silver, copper or an alloy of these or other metals, in order to simplify and speed up the ...

Abstract

The use of enamel as dielectric intermediate layer in the manufacture of heating elements is known. The dielectric enamel layer is herein arranged on a generally metal substrate for heating, after which metal heating tracks are arranged on the dielectric enamel layer by means of silkscreen techniques. The invention relates to an improved heating element. The invention also relates to a liquid container provided with such a heating element.

Description

technical field [0001] The present invention relates to heating elements. The invention also contemplates a liquid container equipped with such a heating element. Background technique [0002] In the manufacture of heating elements it is known to use enamel as a dielectric interlayer. The dielectric enamel layer is here arranged on a generally metallic substrate for heating, after which metal heating tracks are arranged on the dielectric enamel layer by means of screen printing techniques. Such a heating element is for example described in Dutch patent application NL1014601. Described here is, for example, a heating element for heating a liquid in a liquid container or for heating a heating plate, wherein heat is generated by conducting an electric current through at least one heating track. Here, the heating tracks are arranged through the dielectric layer on the substrate for heating. An intermediate layer with dielectric properties not only provides for good transfer ...
