Description

The antifog glass that food display cabinet is used

Technical field

The utility model relates to the exhibiting device field, relates in particular to the antifog glass that uses on the showcase.

Background technology

The food of the heat of placing in the food display cabinet often causes showing that in-cabinet temperature is higher, thereby can at the formation fog on glass of showcase, affect the effect of showing.Usually use at present two kinds of methods automatically to remove showcase fog on glass.The first is the hot blast demist, particularly is exactly to offer exhaust vent at show stand near the place of glass, and provided with fan below show stand utilizes the wind drive hot gas in the exhaust vent to flow, heating glass, thus eliminate fog; But the limitation of this method is: can not guarantee that monolithic glass can both be heated, generally can not eliminate the fog of the first half of glass.The second is the electric-heating-wire-heating demist, i.e. embedded resistor silk between double glazing, and the demist of this method is effective, but is clipped in the silk thread that resistance wire in the double glazing can stay black, affects observability.

The utility model content

The applicant for above-mentioned existing food display cabinet glass except the impact of the resistance wire in bad, the glass of fog effect problem attractive in appearance, carry out Improvement, the antifog glass that provides another kind of food display cabinet to use, it can make monolithic glass all obtain the good fog effect that removes, the vestige that while is transparent and observability is good, do not have the resistance silk thread, and hygienic environment-protecting.

The technical solution of the utility model is as follows:

The antifog glass that a kind of food display cabinet is used comprises the electropane that stacks gradually connection, multiple layer aluminum strip and glass plate; Electropane comprises glass substrate and ITO conducting film attached to it; Be bonded between described electropane and the glass plate after multiple layer aluminum strip is encircled into frame structure, form the intermediate layer, described intermediate layer and extraneous sealing; Described multiple layer aluminum strip is hollow structure, on its inwall opening arranged, and described open communication intermediate layer and cavity are filled with drier in the described cavity; The two ends of described electropane are connected with respectively positive electrode and negative electrode.

Its further technical scheme is: described ITO conducting film device is on glass substrate, and close described multiple layer aluminum strip one side.

The beneficial effects of the utility model are:

1, the intermediate layer between electropane and the glass plate seals with extraneous, and the drier of filling in the multiple layer aluminum strip can guarantee fog not occur in intermediate layer drying, the intermediate layer; ITO conducting film heating power, heat can heating glass plates, thereby eliminate the fog on glass plate and electropane surface;

2, the area of electropane can cover the glass plate of monoblock, thereby can eliminate the fog on monolithic glass plate surface, can not stay the dead angle of demist, good visual effect;

3, ITO conducting film itself is nontoxic, and safety and sanitation are used for the quality that food display cabinet can not affect food;

4, electropane relies on inner minute electronic conduction, does not need to add macroscopic conductor, thereby can not leave the vestige that resistance silk thread etc. affects vision; Its light transmittance and refractive index are good, and be transparent good with observability.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1 and Figure 2, the utility model comprises theelectropane 2 that stacks gradually connection, multiplelayer aluminum strip 3 andglass plate 9; Whereinelectropane 2 comprises glass substrate 2-2 and ITO conducting film 2-1 attached to it, ITO conducting film 2-1 is installed on the glass substrate 2-2, and a side of close multiplelayer aluminum strip 3, thereby prevent that ITO conducting film 2-1 from use damaging because being installed on the outside.Described ITO conducting film 2-1 is tin indium oxide (Indium-Tin Oxide) nesa coating;ITO electropane 2 is in the power house environment of high purification, utilizes the plane magnetic control technology, on ultra-thin glass sputter tin indium oxide conductive film coating, and obtain through the high temperature anneal, its manufacture method belongs to prior art.Multiplelayer aluminum strip 3 is bonded betweenelectropane 2 and theglass plate 9 by gatheringsulphur glue 6 after being encircled into frame structure, andlayer aluminum strip 3 is also bonding with poly-sulphur glue 6 again for each, thus the intermediate layer 8 of formation and extraneous sealing.Multiplelayer aluminum strip 3 is hollow structure, and opening 7 is arranged on its inwall, and opening 7 is communicated with intermediate layer 8 andcavity 10, is filled withdrier 5 in the cavity 10.The upper and lower side ofelectropane 2 is connected with respectivelypositive electrode 1 and negative electrode 4.For the ease of making,positive electrode 1 is starched for the silver that spreads uponelectropane 2 two ends withnegative electrode 4 in the present embodiment.

As shown in Figure 3, be in series withSSR relay 12 in the input circuit of the present utility model, play the effect of protective circuit,SSR relay 12 is parallel withadjusting device 11; Adjustingdevice 11 can be a variable resistor, with the size of current in the regulating circuit.Transformer is added in the operating voltage 36V of 220V voltage transformation to the ITO conducting film on the conducting film 2-1.After ITO conducting film 2-1 energising, the electronics displacement produces thermal effect, thereby eliminates the fog that appears at glass substrate 2-2 andglass plate 9 outsides.

The resistivity of ito thin film can obtain and the similar heating effect of resistance wire near metallic resistance, and simultaneously this conducting film light transmission is good, and it is to transmission of visible light 〉=82%, infrared reflection rate 〉=88%; The more important thing is this material safety non-toxic, suit cashier's office in a shop to use at food show.A multiplelayer aluminum strip 3 can provide reliable support betweenelectropane 2 andglass plate 9, prevent from sticking together behind both compressive deformations damaging ITO conducting film 2-1 by pressure.

More than describing is to explanation of the present utility model, is not to restriction of the present utility model, and the utility model limited range is referring to claim.In the situation of the utility model basic structure, the utility model can be done any type of modification.
