Problems solved by technology

[0006] However, the current glass with electric heating layer, due to the high surface resistance of the electric heating layer, requires a high supply voltage in any case for large-sized window panes or long current paths to be heated. greater than the usual on-board voltage in the vehicle in any case
And using what is disclosed in the above-mentioned patent documents, in figure 1 The setting method of the separation line in the electric heating layer mentioned in the above will also cause only one current path to exist on the large-sized glass, resulting in uneven heating and low heating efficiency; in order to improve the uniformity of heating, one would think of such figure 2 The multi-level separation line is set as shown, but with the increase of the number of levels, the length difference of the current path of each level will become larger and larger, which will also cause problems of uneven heating and low heating efficiency

The electrical heating layer comprises a conductive coating, a first electrode and a second electrode; the first electrode and the second electrode are close to the first side of the conductive coating, and the long sides of the first electrode and the second electrode are approximately parallel to the first side; the conductive coating is provided with a main separation line, and one side of the main separation line is approximately vertical to the long sides of the first electrode and the second electrode; a gap is arranged between the first electrode and the second electrode; one end of the main separation line is arranged in the gap, so that the first electrode is separated from the second electrode, and an area without circulating current is arranged between the first electrode and the second electrode; at least one part of a main current path is formed by a path confirmed along the length direction of the main separation line; and the conductive coating is also provided with grade separation lines which are respectively distributed on the two sides of the main separation line in a way of mirror image. According to the invention, the heating uniformity and the heating efficiency are improved.

Description

technical field [0001] The invention relates to a glass with an electric heating layer used in the fields of automobiles and buildings, in particular to an electric heating layer structure, a method for arranging current paths, an electric heating method, and a panel element with an electric heating layer. Background technique [0002] At present, in the field of decoration, people's demand for heating glass is increasing day by day. In order to increase the temperature of the glass, wires are placed between the layers of glass, said wires being connected to a power source. Heating the glass is especially useful in colder climates to defog and melt snow and ice on the glass. [0003] The existing electric heating glass is mainly to distribute the resistance wire evenly in a straight line between two or more layers of glass, which has the characteristics of uniform heating, high glass transmittance, and is conducive to mass production. [0004] A kind of glass with electric ...
