Abstract

The utility model relates to a frostless glass window of a car, comprising a plurality of hollow interlayers formed by two layers or many layers of glasses which are assembled in parallel in the finite distance. After the surface of the frostless glass window of a car is sprayed with an anti-reflection film, the circumference of the frostless glass window is sealed by the heat-insulated and heat insulating material and then the frostless glass window of a car is loaded into a window frame. The utility model can directly be made from the glasses with a hollow interlayer itself. In certain cases, electrothermal elements can be installed in the hollow interlayer of the glasses to be heated or form a circulation loop of the dry heat air by the air input pipeline and the air output pipeline of the device externally connected with a dry heat air pump, which can enhance the temperature of the hollow interlayer or reduce the humidity of the hollow interlayer, effectively destroy the condition of frost formation and dew generation and reach the purpose of removing the frost. The utility model can be widely used for vehicles with various types.

Description

Frostless glass window of car

The utility model relates to a kind of glass vehicle window, particularly a kind of non-frost glass vehicle window of dew and frosting that also can not condense under the cold climate condition.

The glass vehicle window that installs on the existing various vehicles, regular meeting has the frost layer or the dew that condenses, the visibility that influences the brightness of vehicle window printing opacity and look thing during cold travelling in the sky.As the frosting of chaufeur fwd Windshield with generate dew, except the sight line and road speed that will influence him, also getting into an accident easily causes the accident, and institute thinks and guarantee traffic safety, will scrape by hand usually or defrosting machine defrosting or remove dew.But the former troublesome poeration and not thorough, not only energy consumption is big, cost is high for the latter, and effect is also poor when using on big-and-middle-sized vehicle.

The objective of the invention is to provide a kind of non-frost glass vehicle window simple in structure, easy to use, it adopts the middle glass board with certain hollow sandwich of multilayer to constitute glass for vehicle window, destroy frosting condition, thereby reach the effect of under the cold climate condition, can not condense dew and defrosting.

Fig. 3 is an I position partial enlarged drawing among Fig. 2.

Fig. 4 is the utility model constructional drawing of charged heater element.

Fig. 5 is the local figure of B-B section among Fig. 4.

Fig. 6 is for adopting the utility model constructional drawing of external dry heat air pump.

The utility model comprises glass, window frame, heat-insulating material, heating, dry heat air pump, breather line, the glass for vehicle window that it is characterized in that it is made of at least two-layer glass plate that is parallel to each other by certain interval, its inner layer glass surface scribbles anti-reflection film And can be with heating element heater, realizes being connected with window frame sealing by heat-insulating material around the described glass for vehicle window. See Fig. 1-shown in Figure 3,1,2 is vehicle window plate glass, and 3 is heat-insulating material. Plate glass 1,2 forms one by heat-insulating material 3 pads and window frame 4 and consists of the utility model basic structure. Glass for vehicle window also can adopt the glass material that is made of hollow sandwich at least two-layer plate glass that is parallel to each other, and this moment is as long as directly be inlaid in it in window frame. On some oversize vehicle of the special cold district of weather, also can adopt such as Fig. 4～version shown in Figure 5: in the interlayer that is consisted of by glass plate 6,7, increase heating 5, its two ends respectively by screw 9, nut 8, be equipped with packing ring 10 and fastened on glass for vehicle window. Lead 11 passes insulation material layer 12 and draws, and inserts the low-tension supply that is installed in the vehicle window below, also can directly insert the power supply that vehicle uses. When needed, as long as plugged just can make the heating heating produce heat and outwards distribute, thereby avoid occurring frosting or dew. Also can set up escape pipe 14 above the glass for vehicle window interlayer according to shown in Figure 6 in some cases, air inlet pipe 16 is set up in the below, and external dry heat air pump 15 forms the heated dry air closed circuit. Escape pipe, air inlet pipe can be metal hollow pipelines, also can be the soft pipelines of being made by the rubber and plastic class. During use, heated dry air constantly goes from dry heat air pump 15 obtains hollow sandwich that heat is transported to glass for vehicle window continuously, replenishes outside dispersed heat, keeps the condition of frost-free, reaches the purpose of frost-free.

Compare with the manual Defrost method that strikes off with existing defrosting machine, the utility model has the structure of interlayer by adopting the dull and stereotyped formation of bilayer or compound glass, reach additional settings such as electric heating element, dry heat air pump, the condition of having destroyed frosting reaches the purpose of defrosting or clear defrost water.Simple in structure, to implement easily, defrosting is thoroughly, and is with low cost, and fully without manual operation, its energy consumption is low far beyond other Defrost mode, under general climatic conditions, also the same with common vehicle window, do not influence sight line and light, can be widely applicable for various types of vehicles and use.

An embodiment is provided below.

Increase an area, similar glass board that shape is close at existing automobile window glass internal layer, after the anti-reflection film of surface spraying within it, reinforce the utility model of making as shown in Figure 1-Figure 3 with metal bin with the car frame Nei ， And that packs into after the seal with elastometic washer all around.Through on probation, this device light transmittance and look the thing visibility and all do not have significant change with common glass for vehicle window, the phenomenon that frosting and dew generation are arranged is not realized in use under winter cold climate condition.
