Abstract

The utility model relates to an electric heating frost and dew preventing glass used in refrigeration devices. A plurality of parallel electric heating wires with the electrothermal function are uniformly arranged on a common flat glass in a silk screen printing mode, the parallel heating wires are connected together in series. Every two or more than two heating wires are connected into one group in parallel, each group are connected in series by an edge conducting wire. By using the utility model, the transparent advantage of the existing glass cabinet door is effectively retained, and frost and dew on the cabinet door can be automatically prevented and eliminated. The utility model has the advantages of convenient operation, power consumption saving, easy fabrication and low cost.

Description

Electric heating frost- and dew-resistant glass used in refrigerating unit

The utility model relates to a kind of refrigeration plant that is used for by the novel glass of Electric heating to prevent that its frosting from revealing, promptly a kind of refrigeration plant electrical heating anti-caking frost and dew glass.

Existing refrigeration plant, as refrigerator, commodity display refrigerator, its transparent cabinet door generally all adopts ordinary insulating glass or plate glass, this class transparent glass door, though have the commodity that to see display in the cabinet easily, but owing to the inside and outside temperature difference of cabinet makes the full frost and dew of its surface knot, can't observe freezing, the refrigeration situation of article in the cabinet, influence the performance of its function, and the elimination of frost and dew on this class cabinet door, often need to eliminate frost and dew, therefore exist and use the deficiency inconvenient, that power consumption is big by opening cabinet door or outage a period of time.

The purpose of this utility model just be to provide a kind of have prevent and eliminate cabinet door frost and dew, very easy to use, power consumptive province and refrigeration plant easy to manufacture, lower-cost automatically with electrical heating anti-caking frost and dew glass.

The purpose of this utility model realizes in the following manner: on common plate glass, mode by serigraphy is provided with some parallel heating lines with electric heating function equably, above-mentioned parallel heating line is taked and the mode of connecting links, be that per heating line parallel more than two or two becomes one group, and take series connection by the edge lead between every group.

Description of drawings.

Fig. 1 is a single flat glass sheet example structure schematic diagram of the present utility model;

Fig. 2 is a double layer glass example structure schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.

As shown in the figure, refrigeration plant of the present utility model electrical heating anti-caking frost and dew glass, mainly by plate glass (1), heating line (2) and edge lead (3) are formed, as make the double layer glass form, then also need add face glass (4) on this basis, on common plate glass (1), mode by the prior art serigraphy, according to the size specification of glass planar, some parallel heating lines (2) with electric heating function are set equably, these parallel heating lines (2) are taked and the mode of connecting links, be that per heating line parallel more than two or two becomes one group, then take series system between every group by edge lead (3), general area hour, as the refrigerator cover plate, can adopt per two one group, and area as the commodity display refrigerator, then adopts per four one group to be good when big.

In use, the heating line of glass surface generates heat under the effect of rated voltage, make glass surface produce uniform fuel factor, glass surface frosting or dewfall have been prevented effectively, to keep the transparency of glass cabinet door effectively, this product also can be as required simultaneously, utilizes prior art at above-mentioned electrically heated glass the one side of heating line to be arranged, and adds one deck plate glass again and make double-deck hollow insulation glass.

Adopt refrigeration plant of the present utility model to reveal glass with the electrical heating antifrost, not only effectively kept the transparent advantage of existing glass cabinet door, but also owing to adopted glass surface electric-heating technology and advanced wire laying mode, therefore also having and automatically prevent and eliminate cabinet door frost and dew, very easy to use, power consumptive province and advantage easy to manufacture, lower-cost, is that a kind of comparatively desirable refrigeration plant reveals glass with the electrical heating antifrost.

Claims (3)

1, a kind of refrigeration plant of forming by ordinary plate glass and electric heating heat pyrexia line electrical heating anti-caking frost and dew glass, it is characterized in that on common plate glass, mode by serigraphy is provided with some parallel heating lines with electric heating function equably, above-mentioned parallel heating line is taked and the mode of connecting links, be that per heating line parallel more than two or two becomes one group, and take series connection by the edge lead between every group.

2, refrigeration plant according to claim 1 is characterized in that having at above-mentioned electrically heated glass the one side of heating line with electrical heating anti-caking frost and dew glass, adds one deck plate glass again and makes double-deck hollow insulation glass.

3, refrigeration plant according to claim 1 is characterized in that with electrical heating anti-caking frost and dew glass above-mentioned heating line is to take four to be one group.
