Abstract

The utility model discloses defrog glass used by refrigerators, and at least contains two layers of glass which are placed in parallel with inside intervals , a plurality groups of heating wires which is horizontally arranged on the intervals between the two layers of glass. The heating wires consist of ten groups of heating wires which directly connect in series with the 220V power source of the refrigerator. Compared with the traditional defrog glass, the power source only for the defrog glass is not needed so that the cost of the refrigerator is reduced, the valid space is expanded and the working reliability is increased.

Description

The refrigerator antifog glass

The utility model relates to commercial refrigerating device, more specifically refers to a kind of refrigerator antifog glass.

Commercial refrigerator is quite universal in the use in large supermarket, market, cake room, because the internal and external temperature difference of refrigerator is bigger, the clear glass on it often can be formed the mist frost in frequent use, block people's sight.Remove in order to make mist frost on glass, the insider has designed a kind of antifog glass, this antifog glass contains two layers of glass at least, in the interlayer of two layers of glass, be furnished with the array heating wire, the operating voltage of each group heating wire is for exchanging 22V, and the employed voltage of refrigerator is alternating current 220V, for being reduced to, alternating current 220V voltage exchanges 22V, traditional refrigerator also must be equipped with the power supply of the heating wire work in the antifog glass of specializing in, undoubtedly, the setting of power source special makes the cost of refrigerator increase on the one hand, also taken the useful space of refrigerator on the other hand, the increase of power supply makes the operate as normal reliability of refrigerator reduce besides.

For this reason, the purpose of this utility model is at the above-mentioned shortcoming of the antifog glass existence of traditional refrigerator, proposes a kind of improved refrigerator antifog glass.

To achieve these goals, the utility model adopts following technical scheme, this refrigerator contains two layers of glass, array heating wire at least with antifog glass, two layers of glass is parallel and put, and the centre is left at interval, in the interval of array heating wire horizontal arrangement between two layers of glass, described array heating wire includes ten groups of heating wire, and ten groups of heating wire are connected in series between the alternating current 220V power supply of refrigerator mutually.

The two ends of one deck glass in described two layers of glass are furnished with copper-foil conducting electricity at interval, and described ten groups of heating wire are connected in series mutually by the copper-foil conducting electricity that is furnished with at interval.

Each group heating wire of described array heating wire includes 4 to 8 heating wire.

Because the utility model refrigerator contains two layers of glass, array heating wire at least with antifog glass, two layers of glass is parallel and put, and the centre is left at interval, in the interval of array heating wire horizontal arrangement between two layers of glass, described array heating wire includes ten groups of heating wire, and ten groups of heating wire are connected in series between the alternating current 220V power supply of refrigerator mutually.Ten groups of heating wire are with the voltage averaged pressure of alternating current 220V, operating voltage after each group heating wire dividing potential drop is 22V, it is compared with traditional antifog glass, save the power supply of specializing in antifog glass work, therefore, the cost of refrigerator is reduced, also reduced the useful space of refrigerator on the other hand and increased refrigerator operate as normal reliability.

Below in conjunction with drawings and Examples, the utility model is done one explains:

Fig. 1 is traditional refrigerator antifog glass electricity principle schematic.

Fig. 2 is the heating wire wiring schematic diagram of traditional refrigerator with antifog glass.

Fig. 3 is the utility model refrigerator antifog glass electricity principle schematic.

Fig. 4 is the heating wire wiring schematic diagram of the utility model refrigerator with antifog glass.

Fig. 5 is the utility model refrigerator antifog glass structural representation.

Please consult illustrated in figures 1 and 2 earlier, traditional refrigerator mainly is with array heating wire phase with antifog glass electricity principle and connects, all heating wire 11 all are attempted by between the copper-

foil conducting electricity

12,13 at glass two ends, the operating voltage of each group heating wire is and exchanges 22V, the operating voltage master of this 22V is depressured to 22V (power supply does not draw among the figure) by power source special with the civil power alternating current 220V, this supply power mode obviously as what narrated, needs power source special in background technology.

Please consult Fig. 3 and shown in Figure 4 again,

Refrigerator of the present utility model mainly is to utilize the series connection principle with the principle of the heating wire in the antifog glass, array heating wire 21 is serially connected in mutually between the alternating current 220V of operating voltage of refrigerator.

On concrete structure, the same with traditional antifog glass, this antifog glass contains two layers of glass 24,25 (in conjunction with Fig. 5), array heating wire 21 at least, this two layers of

glass

24,25 are parallel and put, and interval 26 is left in the centre, in the interval 26 of array heating wire 21 horizontal arrangement between two layers of glass, different is, described array heating wire 21 includes ten groups of heating wire, ten groups of heating wire are connected in series between the alternating current 220V of operating voltage of refrigerator mutually, and each group heating wire can be in voltage after partial and exchange 22V.

The two ends of one deck glass 25 in described two layers of

glass

24,25 are furnished with copper-

foil conducting electricity

22,23 at interval, in the figure of present embodiment, be furnished with copper-

foil conducting electricity

22,23 for the two ends of lower floor's glass 25, described ten groups of heating wire 21 are connected in series mutually by the copper-

foil conducting electricity

22,23 that is furnished with at interval, the layout of copper-

foil conducting electricity

22,23 will satisfy ten groups of heating wire 21 and form series connection, and making each group heating wire both end voltage is 22V (under the situation of not considering to fluctuate).

Each group heating wire of described array heating wire 21 all can comprise some heating wire, in the present embodiment, each group heating wire has comprised 4 to 8 heating wire, between the some heating wire of each group in heating wire for being connected in parallel, therefore the voltage of each root heating wire also is and exchanges 22V, and heating wire adopts tungsten filament in the utility model.
