CN2383938Y - Glass without mist and frost - Google Patents

Abstract

The utility model relates to a piece of glass without mist and frost, which comprises an inner layer glass, an outer layer glass and a middle hollow layer. A sealing end arranged at the periphery of the inner layer glass and the outer layer glass is provided with a supporting element and an adhesive element, and a moistureproof element is also arranged at the vicinity of the supporting element and the adhesive element. The utility model is sealed by adopting a combined way of hard supporting element and soft adhesive element, having good sealing effect. In addition, the supporting element controls the thickness of the hollow layer, and the moisture proof element plays moistureproof action. In this way, the utility model not only solves a problem of the glass with mist and frost caused by air temperature and climate variation fundamentally, but also the thickness is similar to that of the existing glass. The utility model has good visible light transmittance and low cost.

Description

Non-fog and non-frost glass

The utility model relates to a kind of automobile-used, civilian construction with, the aviation glass with hollow core.

People know, because the gap of indoor and outdoor temperature and the variation of local climate, the frost mist that always often produces on glass, will be more and more serious if do not remove, for the automobile in travelling, will cause very big difficulty and harm therefore for driver and rider, particularly rainy day and the north cold winter, temperature in the car is outside car, the regulating action of air-conditioning is very limited, frost mist on glass reduces visibility greatly, have a strong impact on the sight line of human pilot, traffic accident easily takes place, a lot of calamitous traffic accidents all cause because of frost mist.At train, aircraft, civilian construction and industrial circle, frosting on glass is hazed and is also made us suffering untold misery equally, influence seriously or the safety of life and property that directly threatens people.Therefore, it is very urgent to solve the problem of frost mist on glass.At present, solving the common way of glass frost mist problem both at home and abroad is with cloth or paper wiping, while for the driver, just must drive to wipe, and must ceaselessly wipe, so both inconvenience was also dangerous.In recent years, a kind of electric ehated glass occurred, in glass, sandwiched heating wire to reach the purpose of defrosting-defogging, but heating wire influences visibility equally, and is also not attractive in appearance, and this type of product cost height, therefore generally only be used for the rear window of high-grade automobile, its result still can't resolve root problem.China's utility model patent 97202954.0 has been announced a kind of windscreen for vehicle, it is by glass outer, inner layer glass and hollow layer constitute, layer glass is passed through the mother-son groove sealing structure at sealed end, also has the groove that hygroscopic agent is housed that communicates with hollow layer at mother-son groove structure place, up to the present the glass of this structure only limit to can realize in theory, because also windshield is not processed the equipment of mother-son groove at home and abroad, even this kind equipment occurred in the future, the percent defective height of its processing, cost is also very expensive, and the thickness of corresponding requirements glass is thicker, the so thick visible perspectivity of glass is poor, and impact resistance is not strong, poor durability, life-span is short, so not available.

The purpose of this utility model is to provide the non-fog and non-frost glass that a kind of cost is lower, antifrost antifogging is effective at the above the deficiencies in the prior art.

The purpose of this utility model is achieved in that the utility model comprises inner layer glass, glass outer and middle hollow layer, sealed end around aforementioned inner layer glass and glass outer is provided with support member and bond, also is provided with vapor barrier near support member and bond place in hollow layer.

Technique effect of the present utility model is: the utility model seals in the mode that the sealed end of inside and outside layer glass adopts hard support member and soft bond to combine, good sealing effect, adopt the thickness of support member control hollow layer in addition, adopt vapor barrier to play moisture-proof role, the utility model has not only fundamentally solved because the problem of mist on the frost on glass that the variation of temperature and weather causes like this, and thickness and existing glassy phase are seemingly, and visual transparency is good, and cost is low.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the section of structure of the utility model embodiment one.

Fig. 2 is the section of structure of the utility model embodiment two.

Fig. 3 is the section of structure of the utility model embodiment three.

As shown in Figure 1, the utility model embodiment one comprises inner layer glass 1 and glass outer 2, the gap that one 0.6-1.2mm is arranged between layer glass is a hollow layer 3, this hollow layer 3 is vacuum layer in the present embodiment, inner layer glass 1 and glass outer 2 are tempered glass, sealed end around inner layer glass 1 and glass outer 2 is provided with the support member 4 of metal, all there is the PVB glue-line of one deck as bond 5 inner face and outside at support member 4, support member 4 and bond 5 seal jointly, support member 4 has also guaranteed the accurate size of hollow layer 3 thickness simultaneously, bond 5 also plays bonding inner layer glass 1 and glass outer 2 simultaneously, and bond 5 places near internal layer in hollow layer 3 also are provided with vapor barrier 6.

As shown in Figure 2, embodiment two is that with the difference of embodiment one glass outer 2 of embodiment two is a middle gapless double-layer glass, and a doubling layer 7 is arranged between double-layer glass, and other structure of embodiment two is identical with embodiment one.

As shown in Figure 3, the inner layer glass 1 of embodiment three is and the identical double-layer glass of embodiment two glass outer structures with glass outer 2, and a doubling layer 7 is arranged between double-layer glass.Other structure of embodiment three is with embodiment one.

In addition, it is single-glass that the utility model can also be made glass outer, and inner layer glass is the structure of double-layer glass; Bond can be that inside and outside at support member all has, and also can only be provided with one deck in the inner face or the outside of support member, and vapor barrier always is positioned at their inner face.
