Abstract

The utility model discloses glass capable of preventing dewing on a surface, belonging to the technical field of building material. The utility model is suitable for a windscreen, a mirror surface, an observation window, etc. The utility model is characterized in that a surface of transparent medium material which can not resist high temperature is combined with one layer of transparent electric conduction heating film; the upper part of the film is coated with one layer of transparent insulation film; the edge of the transparent electric conduction heating film is provided with two bar-shaped electrodes; the transparent electric conduction heating film can generate heat to regulate voltage to control the temperature of a surface of the glass through an electrode of a conducting wire and a power supply, which can prevent the surface of the glass from generating harmful dewing. The utility model has the advantages of low power consumption, homogeneous heat generation, and safe and convenient usage. The utility model can thoroughly eliminate dewing.

Description

Prevent the glass of surface sweating

The utility model prevents that the glass of surface sweating from relating to building material technical field, is applicable to windshield glass, minute surface and viewing window etc.

At present, in the season of cold, because internal-external temperature difference and damp-heat air are met the deleterious dewfall phenomenon of cold formation on these object surfaces.As automobile under steam, the fog that the inner surface of its front windshield rises exists the sight line that has a strong impact on navigating mate, brings the problem of hidden danger to traffic safety; And for example also there is the dewfall phenomenon on the viewing window surface of mirror surfaces in the bathroom or broadcasting studio, exists situation smudgy or that transparency reduces.

The purpose of this utility model provides a kind of glass that can prevent surface sweating, need use the utility model, surface sweating in the time of can preventing to use in the winter time on the traditional product of maintenance transparency many.

The utility model is a kind of to prevent that the design (Fig. 1-2) of the glass of surface sweating from being by transparent dielectric material (1), electrically conducting transparent heating film (2), and transparent insulating film (3) and strip electrode (4) are formed.It is to adopt special process multiple metal oxide to be compounded on the surface of transparent dielectric material (1) of non-refractory (as glass that its structure connects, synthetic glass etc., form the electrically conducting transparent heating film (2) that one deck has high light transmittance energy and the certain resistance value of unit surface, cover layer of transparent insulating film (3) more in the above, mounting edge position at product makes two strip electrodes (4) for the electrically conducting transparent heating film with methods such as silver-plated or crimping metallic membranes, when adding power supply with two electrodes, the electrically conducting transparent heating film will generate heat, change the electrode both end voltage, just can regulate the glass surface temperature, thereby reach thorough elimination surface sweating phenomenon.

The utility model prevents that the effect of the glass of surface sweating from being compared with prior art: 1, because this glass has been conceived the electrically conducting transparent heating film, when two strip electrodes of giving the edge add power supply, the electrically conducting transparent heating film will generate heat, regulating voltage is may command glass surface temperature just, thereby can reach the purpose that prevents the glass surface dewfall, it is thorough, easy to use to eliminate dewfall; 2, because the electrically conducting transparent heating film is to be compounded in the transparent dielectric material surface uniformly, and heating is even, and it is very low to eliminate the required power consumption of dewfall, and temperature rise is not high, damages transparent dielectric material and insulating film so be unlikely, and can use the LVPS power supply; 3, owing on the electrically conducting transparent heating film, having covered the layer of transparent insulating film again, therefore, safe in utilization.

Fig. 1 is the vertical view that the utility model prevents the glass of surface sweating;

Fig. 2 is an A-A direction sectional view among Fig. 1.

The utility model prevents that the embodiment of the glass of surface sweating from being the shield glass of producing a 500 * 1200mm, using prior art promptly uses the toughened glass of thick a 500 * 1200mm of 5mm as transparent dielectric material (1), metal oxide with the thick 500 * 1200mm of 0.02mm is compounded on the toughened glass transparent dielectric material as electrically conducting transparent heating film (2), plastic, transparent insulating film (3) covering with the thick 480 * 1200mm of 0.01mm is bonded on the electrically conducting transparent heating film (2), connects 12V power supply formation in strip electrode (4) and the car with lead.

Claims

1, a kind of glass that prevents surface sweating, the surface recombination layer of transparent conductive exothermal film (2) that it is characterized in that transparent dielectric material (1) at non-refractory, transparent insulating film (3) covers on the electrically conducting transparent heating film (2), and two strip electrodes (4) of electrically conducting transparent heating film edge constitute by wire connecting power.

2, the glass that prevents surface sweating according to claim 1 is characterized in that the electrically conducting transparent heating film makes with multiple metal oxide, transparent dielectric material glass, and synthetic glass constitutes.
