Abstract

The utility model provides a glass door body of the ice chest, comprising a frame and two-layer glass plates embedded in the frame. A hollow layer is arranged between the two-layer glass plates; sealing material and desiccant are arranged on the edge of the hollow layer; one of the two-layer glass plates is high vacuum insulation glass. Because the utility model adopts the high vacuum insulation glassy layer, the convection current conduct of the air is stopped; the heat-insulating property is increased; the preventing frost dew property is simultaneously increased. Because the edge and an air outlet of the high vacuum insulation glass are formed by the sealing of the inorganic material under the condition of the high temperature, the middle vacuum layer can be kept constant in more than ten years; the insulating property is stable for a long time.

Description

The novel freezer glass door body

Technical field

The utility model relates to a kind of vitals of ice box, particularly a kind of novel freezer glass door body.

Background technology

In the prior art, the door body of ice box generally adopts the individual layer low-radiation film coated glass to make; Require better employing one deck low-radiation film coated glass to answer one deck simple glass again and become hollow glass door body.This its heat insulation effect of glass door of refrigerator body has very big defective, especially in the specification requirement that can not satisfy ice box aspect the anti-frosting condensation performance.In order to solve present ice box frosting condensation trouble, in the prior art, generally be to adopt the charged heating film glass of compound last layer.Though and this technology has solved the frosting dewfall phenomenon of freezer door body, energy resource consumption and manufacturing cost have been increased.

Summary of the invention

The purpose of this utility model just provides a kind of novel freezer glass door body, solving the frosting condensation trouble that existing double glazing freezer door body exists, and the door body of charged heating film the glass energy resource consumption and the high problem of manufacturing cost that exist.

The technical solution of the utility model is: comprise frame and be embedded in the interior layer glass plate of this frame, between the layer glass plate, leave hollow layer, be provided with encapsulant and drier at the edge of this hollow layer, it is characterized in that: one of described layer glass plate is a high vacuum insulation glass.

The formation of described high vacuum insulation glass is with laying some supporting pads in the middle of a slice simple glass plate and a slice low emissivity glass sheet, through high temperature with the vacuum sealing material sintering together with two glass sheets, high vacuum layer (vacuum is about 10Pa) will be pumped into by vacuumizing the mouth of pipe in the middle of two glass plates then, to vacuumize the mouth of pipe again shuts, make it keep stable vacuum state, thereby form the door body component of a high insulation, this high door body component and another piece glass plate that is incubated is formed the hollow thermal insulation layer by the hollow sealing material seal together.Edge and exhaust outlet are to adopt inorganic material high temperature sealed knot to form.

The encapsulant of described vacuum sealing material and exhaust outlet is inorganic material.

The high vacuum insulation glassy layer that the utility model adopted has been stopped the convection current conduction of air, and its heat-proof quality is improved greatly, has also improved anti-frosting condensation performance simultaneously greatly.Because the edge of high vacuum insulation glass and exhaust outlet are to adopt inorganic material high temperature sealed knot to form, so middle vacuum layer can keep the more than ten years constant, make its heat-insulating property long-term stability.

Fig. 2 is that a side glass plate of the present utility model is the sectional structure schematic diagram of the embodiment of arc for dull and stereotyped, opposite side glass plate;

Fig. 3 is the sectional structure schematic diagram of high vacuum insulation glass of the present utility model.

The specific embodiment

Referring to Fig. 1 and Fig. 2, the utility model comprises frame 1, simple glass 2 and high vacuum insulation glass 3, simple glass plate 2 and high vacuum insulation glass 3 are embedded in the frame 1, leave hollow layer 4 between

layer glass plate

2 and 3, are provided with encapsulant and drier 5 at the edge of this hollow layer 4.Simple glass plate 2 among Fig. 1 is dull and stereotyped, and the simple glass plate 2 among Fig. 3 is the arc that outwards protrudes.

Referring to Fig. 3, described high vacuum insulation glass 3 comprises ordinary plate glass 31, low-emission coated (low-E) glass 32, supporting pad 33 and glass vacuum sealing material 34, lay some supporting pads 33 between ordinary plate glass 31 and the low radiation coated glass 32, seal sintering together by glass with vacuum sealing material 34 between the edge, be pumped into high vacuum layer 36 (vacuum is about 10Pa) by bleeding point 35 in the middle of two sheet glass, to vacuumize the mouth of pipe again shuts, make it keep stable vacuum state, thereby form the door body component of a high insulation, this high door body component and another piece glass plate that is incubated is formed the hollow thermal insulation layer by the hollow sealing material seal together.Edge and exhaust outlet are to adopt inorganic material high temperature sealed knot to form.
