Description

Electric ehated glass

Technical field

The utility model is relevant with glass, in detail, refers in particular to a kind of electric ehated glass, and its inner clamps is provided with the transparent electric heating sheet, supplies heating with elimination water smoke, and can promote heating installation efficient.

Background technology

In the winter and the rainy season of cold, because factors such as the temperature difference of outdoor environment and automotive interior and humidity, airborne hydrone very easily is condensed in the vehicle glass surface and forms water smoke, sight line to motorist forms obstruction, influence traffic safety, a kind of sheet type electric heating piece (being commonly called as the demist hot line) that is attached at windshield for eliminating these water smoke, developing then.

Aforementioned sheet type electric heating piece is to utilize soft perspex sheet as substrate, utilize copper alloy to unroll at substrate surface and arrange formation continous way circuit, when electric current passes through copper circuit, produced heat energy by its resistance, these electric heating pieces are owing to the transparent good of substrate and comparatively soft, and can be attached at the article that windshield etc. has the arc curved surface, the characteristic of energising back heating can make the aqueous vapor that is attached to windscreen surface volatilize fast, avoids hydrone to be condensed in the sight line that windscreen surface hinders the driver.

Consider based on travel safety, windshield is to the requirement height of perspectivity, but, known sheet type electric heating piece is formed at the copper metallic circuit of substrate and but can't has an X-rayed, for avoiding hindering driver's sight line, so the density that these metallic circuits are arranged is low, the adjacent lines section is to each other apart from big, be beneficial to driver's sight and look the outer state of car, add, if the too high board structure that easily causes of metallic circuit temperature rise changes and albefaction, and windshield is easily owing to excessive temperature differentials chaps, so the demist hot line generally carries out demist with the low temperature heating system, but because the metallic circuit distribution density of heating is low, it is slow to cause it to remove fog effect.

The utility model content

The utility model purpose is to provide a kind of electric ehated glass, eliminates efficient and ease of use to improve water smoke.

For achieving the above object, the electric ehated glass that the utility model provides, it mainly comprises two glassy layers, two glued membranes and an electric heating piece, wherein, this electric heating piece is located between this each glassy layer, and these electric heating piece both sides are gluedd joint gummed formation electric ehated glass respectively by this each glued membrane and this each glassy layer;

This electric heating piece mainly has a substrate and a conducting film, wherein, this substrate is the good sheet material of the transparency, this conducting film is located at this substrate surface, and the transparent membrane that this conducting film is made of tin indium oxide, these conducting film two ends are set up the convergence part that is made of the conduction material separately and are connected lead, make electric current pass through this conducting film and produce heat energy, eliminate efficient and easy to use to improve water smoke.

Described electric ehated glass, wherein this convergence part is the conductive foil of wire, and this each convergence part is the opposing parallel shape each other, for the guiding electric current by this conducting film.

Described electric ehated glass, wherein this substrate is constituted by the transparent material of disconnected hot excellence, blocks the side transmission of the heat energy of this conducting film generation to electric ehated glass according to this, for improving electrothermal efficiency.

Described electric ehated glass, wherein this electric heating piece has two conducting films, and this each conducting film is located at this substrate both side surface respectively, and heat up respectively heating these conducting strip both sides of confession.

By enforcement of the present utility model, can make electric current pass through this conducting film and produce heat energy, eliminate efficient and ease of use for improving water smoke.
