[background technology]
In the prior art, the door body of ice box generally adopts single-glass to make, face and generally be to adopt transparent glass to make, and the transparent ice box door body that this single-glass is made makes the user can not open ice and refuses the article that door is just seen the inside.As place some melons and fruits bright in colour, effect is pleasant, face and before getting thing, can see the article in the refrigerator in advance, can directly reach after opening the door, reduce the time that the back of opening the door is sought, can reduce cold air consumption, conservation of power, but the transparent ice box door body heat insulation effect that this single-glass is made is very poor, and often needing to increase other structure increases its heat insulation effect.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of to have a double-layer vacuum heat insulation, face and high insulating effect, the freezer door that the coefficient of heat conduction is little.
The purpose of this utility model is achieved in that
A kind of freezer door is characterized in that it comprises glass outer, inner layer glass, is provided with intermediate glass layer between described glass outer and the inner layer glass, forms first vacuum chamber between intermediate glass layer and the glass outer; Form second vacuum chamber between intermediate glass layer and the inner layer glass; The edge of first vacuum chamber and second vacuum chamber is provided with the vacuum space parting bead and the outer field sealant layer of internal layer; Be filled with argon gas in first vacuum chamber and second vacuum chamber.
Aforesaid a kind of freezer door is characterized in that posting the low emissivity glass film between the described glass outer and first vacuum chamber and between the inner layer glass and second vacuum chamber.
Aforesaid a kind of freezer door is characterized in that posting the low emissivity glass film between the described intermediate glass layer and first vacuum chamber and second vacuum chamber.
Aforesaid a kind of freezer door is characterized in that being filled with the 3A molecular sieve in the described vacuum space parting bead;
Aforesaid a kind of freezer door is characterized in that being provided with butyl rubber sealant between described vacuum space parting bead and intermediate glass layer and the glass outer.
Aforesaid a kind of freezer door, the transmitance that it is characterized in that described low emissivity glass film is greater than 80%.
Aforesaid a kind of freezer door, the transmitance that it is characterized in that described low emissivity glass film is greater than 80%.
The utility model is provided with two vacuum chambers, comprise first vacuum chamber and second vacuum chamber, and post the low emissivity glass film at glass outer and inner layer glass, this just makes that heat insulation effect of the present utility model is very good, the coefficient of heat conduction is below the 0.9W/ (m.K), and be provided with two layers of band in the edge one of first vacuum chamber and second vacuum chamber, the vacuum space parting bead and the outer field sealant layer that comprise internal layer, make first vacuum chamber and second vacuum chamber reach sealing fully, good sealing effect, make win vacuum chamber and the second vacuum chamber vacuum keep best always, prolonged its service life.

[specific embodiment]
A kind of freezer door, it comprises glass outer 1, inner layer glass 2, is provided with intermediate glass layer 3 between described glass outer 1 and the inner layer glass 2, forms first vacuum chamber 4 between intermediate glass layer 3 and the glass outer 1; Form second vacuum chamber 5 between intermediate glass layer 3 and the inner layer glass 2; The edge of first vacuum chamber 4 and second vacuum chamber 5 is provided with the vacuum space parting bead 6 and the outer field sealant layer 7 of internal layer; Be filled with argon gas in first vacuum chamber 4 and second vacuum chamber 5; Post low emissivity glass film 10 between the described glass outer 1 and first vacuum chamber 4 and between the inner layer glass 2 and second vacuum chamber 5.The utility model is owing to be provided with first vacuum chamber 4 and second vacuum chamber 5, and post low emissivity glass film 10 at glass outer 1 and inner layer glass 2, this just makes that heat insulation effect of the present utility model is very good, the coefficient of heat conduction is little, face is provided with two layers of band in the edge of first vacuum chamber 4 and second vacuum chamber 5, the vacuum space parting bead 6 and the outer field sealant layer 7 that comprise internal layer make first vacuum chamber 4 and second vacuum 5 reach sealing fully, good sealing effect.
The utility model can also post low emissivity glass film 10 between intermediate glass layer 3 and first vacuum chamber 4 and second vacuum chamber 5, the transmitance of low emissivity glass film 10 is greater than 80%, this low emissivity glass film has the effect that good blocking radiant heat sees through, winter, the heat radiation that it distributes room heater and indoor object can be as a hot mirror, and most reflected backs are indoor, guarantee that indoor heat does not does not scatter and disappear to outdoor, saves heat cost from face.In summer, it can stop in the heat radiation inlet chamber that outdoor ground, building send, and saves the air conditioner refrigerating expense.Face and low emissivity glass film visible reflectance are lower than the visible reflectance of common solar control film generally below 30%, can avoid causing reverberation to pollute.
Be provided with butyl rubber sealant 8 between described vacuum space parting bead 6 and intermediate glass layer 3 and the glass outer 1, increase sealing.
As shown in Figure 3,1 is glass outer, 2 is inner layer glass, 3 is intermediate glass layer, 11 is the glass outer outside, the outermost of freezer door just, 12 is the inwall of glass outer, 31 is the outer wall of intermediate glass layer, 32 is the inwall of intermediate glass layer, 21 is the outer wall of inner layer glass, 22 is the inner layer glass inboard, the inner face of freezer door just, the present invention is posting low emissivity glass film 10 between the described glass outer 1 and first vacuum chamber 4 and between the inner layer glass 2 and second vacuum chamber 5, just post low emissivity glass film 10 at the inwall 12 of glass outer and the outer wall 21 of inner layer glass, can also be to post low emissivity glass film 10 between intermediate glass layer 3 and first vacuum chamber 4 and second vacuum chamber 5, just outer wall 31 and the inwall 32 in intermediate glass layer 3 also posts low emissivity glass film 10, forms two to four layers low emissivity glass film 10.
Be filled with the 3A molecular sieve in the vacuum space parting bead 6, the 3A molecular sieve claims the KA molecular sieve again.Its aperture is about 3 dusts, and it has the following advantages: (1) 3A molecular sieve adsorbed water, not oxygen in the absorbed air and nitrogen; (2) the 3A molecular sieve is an alkalescent, and pH value is 10.5, can not cause damage to the aluminum strip in the double glazing; (3) 3A molecular sieve rate of water absorption is fast, and rate of water absorption is 0.04g/s; (4) 3A molecular sieve water absorption is big, water absorption 〉=20%; (5) the 3A molecular sieve does not produce the hydrolysis suction at normal temperatures.So the 3A molecular sieve is applicable to the drying of gas and liquid, the dehydration of hydrocarbon; Help the drying of air in the double glazing, the drying of cold-producing medium.
Structure of the present invention can also be applied in wine cabinet, refrigerator, reaches other refrigeration, reach in freezer.
