Electrodes 4 are arranged on the back surface of the base plate of the fresco 3 which is coated with a picture 2; the electrodes 4 are connected with the socket of a power supply 8; an electric heating coating material layer 5 is coated on each electrode 4, and the electric heating coating material layer 5 is also coated between the electrodes 4; an insulation coating layer 6 is coated on the electric heating coating material layer 5. The utility model combines decoration and heating into integration, and the utility model has the advantages of low cost, beautiful appearance and utility.

Description

The mural painting electric heater

The utility model relates to a kind of electric heater, particularly a kind of mural painting electric heater.

Disclosed various electric heaters generally are to select for use heating wire to make in the prior art, and its purposes is to be used for heating, does not possess decoration function.

The purpose of this utility model provide a kind ofly collect decoration, heating is the mural painting electric heater of one.

In order to achieve the above object, the utility model is realized by following scheme.It comprises picture, draws substrate, picture is mounted and is being drawn on the substrate, and its design feature is to be shaped on electrode at the another side (back side) of drawing substrate, and electrode links to each other with supply socket, scribbling an electric-heating coatings layer on the electrode and between the electrode, on the electric-heating coatings layer, scribble a coatings layer.

For increasing the decorative effect and the service life of mural painting electric heater, draw on the substrate and load onto framework, adorn a baffle at the behind face of drawing substrate, baffle is connected with framework.

The utility model collection is decorated and heating is one, and manufacture craft is simple, and is with low cost, and energy-saving safe is both artistic and practical.

Fig. 1 is the user mode figure of a kind of embodiment of the utility model;

Fig. 2 is an A-A profile among Fig. 1.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Picture 2 is mounted and is being drawn on the substrate 3; framework 1 is housed on the substrate 3; the electrode 4 that copper mesh line that the useful thermal conductivity in the back side of substrate 3 is high or copper sheet are made; two end points places of electrode 4 are welded with wiring; wiring is connected with socket 8, scribbles a high-efficiency electric-heating dope layer 5 between the electrode 4 and on the electrode 4, scribbles a special isolation dope layer 6 above the high-efficiency electric-heating dope layer 5; baffle 7 is positioned at the back of picture substrate, is connected with framework 1.

The utility model picture temperature is not higher than 70 ℃, thereby guarantees the nondiscolouring of picture table.The power of high-efficiency electric-heating dope layer calculates (empirical equation) with following formula: $T=k\frac{w}{S}$ Surface area k-empirical coefficient (generally getting 0.5-0.15) w-power of T-picture surface temperature s-high-efficiency electric-heating dope layer 5

For big picture, can separate high-efficiency electric-heating dope layer 5 and be coated with, meet design requirement with the series and parallel method.

Claims (2)

1, a kind of mural painting electric heater, it comprises picture (2), draws substrate (3), picture (2) is mounted and is being drawn on the substrate (3), it is characterized in that: be shaped on electrode (4) at the back side of drawing substrate (3), electrode (4) links to each other with supply socket (8), upward and between the electrode (4) scribble an electric-heating coatings layer (5) at electrode (4), scribble a coatings layer (6) above the electric-heating coatings layer (5).

2, according to the described mural painting electric heater of claim 1, it is characterized in that loading onto on the picture substrate (3) framework (1), to draw the back of substrate (3) and adorn a baffle (7), baffle (7) is connected with framework (1).
