Abstract

The utility model discloses an electrically heating mi-hollow glass, composed of glass (1) with conductive film, glass (2), an electrode (5), a power adjusting device (7), and an electrically heating wire (8). The electrode (5) is symmetrically arranged on the glass (1) with conductive film, the glass (2) and the glass (1) with conductive film are formed into a mid-hollow structure by the method that a division bar (9) is arranged, and circumference is sealed with mid-hollow glue (6). The power adjusting device (7) used for adjusting the conductive film is connected in series with a lead wire of the electrode (5), and the electrically heating wire (8) is arranged at the lower part between the glass with conductive film and the glass. The utility model has the advantages of good performance, beautiful appearance, and low cost, and solves the problems that the power of the, mid-hollow glass can not be adjusted, the electrode is visual, light permeability is poor, manufacture and production are complex, and the phenomenon of dewing can happen.

Description

The electric heating double glazing

The utility model belongs to the double glazing technical field, and what relate generally to is a kind of electric heating double glazing.

At present, the processing method of the electric heating double glazing of domestic production employing has membrane process and conductive filament method.Described membrane process be exactly therein a slice glass surface stick conductive film, add top electrode in the film both sides, with the synthetic hollow of another sheet glass, draw lead.Its shortcoming is that heating back conductive film is easily aging, and glass surface can be seen electrode, and is not attractive in appearance.Electrode needs when glass tempering, processes by silk screen printing with the silver slurry.But silk screen printing easily produces leak source, outage in the time of promptly can causing the product energising, and silk screen processing bothers, consumptive material is many, cost is high.Described conductive filament rule is to add heating wire at glass surface, adds top electrode in the heating wire both sides, and the electrode both sides are drawn lead and formed.It also exists glass surface can see electrode, not attractive in appearance, and electrode needs to process by silk screen printing with the silver slurry when glass tempering, but silk screen printing easily produces leak source, outage in the time of can causing the product energising.And silk screen processing bothers, consumptive material is many, the cost height.Since the electric heating double glazing of producing with above-mentioned two kinds of methods all exist to some extent service behaviour instability, the temperature difference greatly, technical problems such as non-uniform temperature, the easy oxidation of Electric radiant Heating Film, thereby domestic refrigerator industry mainly relies on external import electric heating double glazing.But still there are drawbacks such as the temperature difference is big, electrode is visual, power is non-adjustable in it.And limited by glass size, refrigerator manufacturer can not be by the customer requirement design size, and the financial burden that this has not only increased refrigerator manufacturer has greatly also improved production cost.

The purpose of this utility model promptly produces thus, propose a kind of function admirable, aesthetic in appearance, cheap, have a narrow range of temperature, adjustable power, can prevent to doubt the electric heating double glazing that reveals.

For achieving the above object, the utility model is achieved through the following technical solutions: it is made up of electropane, electrode, parting bead, glass, heating wire and power regulation device, electrode is symmetricly set on the electropane, glass forms hollow structure by parting bead and electropane, hungry area sealing in using in its four limits week; Heating wire is arranged on the bottom between electropane and glass, and the power regulation device that is used to regulate conducting film power is serially connected in the lead-out wire (lead) of electrode.

The utility model reasonable in design, cost is cheap, is lower than imported product 35%.Can directly process, need not do screen printing process again, and conductive film layer is handled through tempering by the customer requirement size, film performance is more stable, and is stronger with the matrix tack, and four limits are through strict insulation processing, can prevent oxidation, improve the useful life of product.After glass is heated, product rete no change.Electrode adopts silver foil to make, and can arbitrarily adjust, and electrode is reinforced in the glass both sides, and the glass rete is stable, and simultaneously available heating wire is adjusted temperature and adjusted voltage with the power modulator, satisfies the demand of different designs at any time.Charge into an atmospheric inert gas in the air in synthetic, the glass surface temperature is even, and fail safe is good.Glass surface be can't see electrode, and is elegant in appearance.After tested, its every performance index reach:

1, under user mode light transmittance greater than 80%.

2, in relative humidity greater than 80% o'clock, the insulation resistance of each conductive component and each insulation division interdigit 〉=10M Ω.

3, heat the component resistance error less than 3 Ω.

4, the insulation resistance between each position is less than 50M Ω.

5, the surface temperature each point temperature difference is even, and surface temperature difference is less than 3 ℃.

6, down energising two hours still can operate as normal for normal temperature, the product crack-free.

The utility model drawings attached:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 1 is the utility model cutaway view.

Accompanying drawing 1 is transferred the pocket circuit theory diagrams for the utility model power.

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

Shown in Fig. 1-2: present embodiment is made up of electropane 1, glass 2, electrode 5, power voltage regulator 7 and heating wire 8, electrode 5 is symmetricly set on the electropane 1, glass 2 forms hollow structures with electropane 1 by parting bead 9, in fill inert gas, four limits week with in hungry area 6 sealings.Electrode 5 adopts silver foil to make, and can arbitrarily adjust resistance, is convenient to processing, to adapt to different clients' demand.For avoiding seeing electrode from glass surface, electrode can be placed on the parting bead 9, just can't see electrode after the synthetic hollow, improved the aesthetic property of product.The power regulation device 7 that is used to regulate conducting film power is serially connected in the lead-out wire (lead) 4 of electrode 5, and as shown in Figure 3: it is made up of potentiometer W, controllable silicon CT, resistance R, capacitor C and diac CF.Its effect is to change the angle of flow that is added on the controllable silicon by potentiometer, reaches the purpose of phase-shift voltage regulating, and the power of final regulating load (conducting film) is to adapt to the instructions for use of varying environment.And it is an external, thereby uses easy to maintenance.Drawback for preventing that the electric heating double glazing from occurring non-uniform temperature in use, having rete to change is provided with the heating wire 8 that is used for compensate for heat energy in the bottom of double glazing, hungry area was 3 times during this heating wire was hidden in, and does not influence the aesthetic property of glass.Be used to regulate on the lead-out wire of heating wire 8 power and also can be connected in series power regulation device 7.Present embodiment is regulated the power of conducting film and heating wire according to environment for use respectively by power regulation device 7 in use, makes it be in optimum Working, has a narrow range of temperature, do not have condensation, purpose that light transmission is strong to satisfy the different requirements of client, to reach.
