Has the advantages of convenient installation, no occupation of the room, low price, beautiful appearance and the like. Meanwhile, the released infrared rays are beneficial to the human body, and the like.
However, the existing mural type electric heater generally has potential safety hazards, some electric heating murals do not have a temperature sensor, or only have one temperature sensor and cannot sense the temperature of a far part, so that a power supply cannot be timely cut off after the electric heating murals are locally overheated, and a human body is scalded or a fire disaster is caused.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a mural painting formula electric heater, concrete technical scheme is as follows:
the mural electric heater is characterized by sequentially comprising a reflecting layer, a heating layer and a picture layer from back to front, wherein a plurality of heating film strips are uniformly arranged on the front surface of the heating layer in parallel, copper electrode plates are arranged at two ends of each heating film strip, the width of each copper electrode plate is consistent with that of each heating film strip, and a silver coating is arranged at the connecting part of each heating film strip and the corresponding copper electrode plate and used for reducing the impedance between each heating film strip and copper coating; copper electrode plates arranged at two ends of the heating film strip extend from the front surface to the back surface of the heating film layer and are connected to a control chip through a lead; the back of the heating film layer is provided with temperature sensors corresponding to the positions of the heating film strips on each front face, all the temperature sensors are connected to the control chip, and the heating layer is wrapped by an insulating and heat-insulating film.
Further, the heating membrane strip is made of PTC semiconductor heating ceramic materials.
Further, the insulating and heat-insulating film is an aluminized PET film.
