Abstract

The utility model discloses a radiation-free electric heating wire. The radiation-free electric heating wire is composed of a core wire, an inner insulator, an electric heating wire, an external insulator and a shielding layer. The radiation-free electric heating wire is characterized in that the internal insulator is wrapped on the exterior of the core wire; the electric heating wire is wound on the inner insulator; the external insulator is wrapped on the exterior of the electric heating wire; and the shielding layer is sprayed and coated on the external insulator. When the core wire is connected in series with the electric heating wire for utilization, magnetic field radiation of the electric heating wire can be mutually offset because that current directions are opposite to each other; and electric field radiation produced by the electric heating wire can be shielded by the shielding layer at an external layer of the electric heating wire and can be eliminated through a power source ground wire, and therefore, purposes of inexistence of magnetic field radiation and avoidance of electric field radiation leakage can be ultimately achieved when the electric heating wire is in a working state, thereby enabling an authentic radiation-free electric heating wire. The radiation-free electric heating wire is also characterized in that the outer diameter of the electric heating wire can be made small with low cost. The radiation-free electric heating wire is most suitable for producing products such as radiation-free electric blankets.

Description

Radiationless heating wire

Technical field

The utility model relates to a kind of radiationless heating wire, belongs to the heating household appliance technical field.

Background technology

The used line with heating function of the electric blanket of selling in the market is the safeguard measure of unshielded radiation all; when using electric blanket, the consumer will among electromagnetic radiation, use the electric blanket time the longest, nearest because people spread; radiation is the strongest, so the harm of electric blanket Radiation On Human body is maximum.

In order to eliminate the harm of electric blanket Radiation On Human body, will at first solve the radiation problem of heating wire used in the electric blanket.Through investigation and patent retrieval, also there is not a kind of radiationless heating wire in the existing market, so electric blanket on the market has radiation.

Summary of the invention

The problem that does not have radiationless heating wire and existing electric blanket ubiquity hazards of electromagnetic radiation health in order to overcome market, the utility model provides a kind of radiationless heating wire that can eliminate electromagnetic radiation, utilize this technology production technology simple, cost is low, and electromagnetic-radiation-free harm.It is a kind of radiationless heating wire of existing electric blanket first-selection.

The utility model technical scheme that adopts of dealing with problems is: a kind of radiationless heating wire, formed by heart yearn, interior insulator, heating wire, outer insulator, screen, it is characterized in that: outside heart yearn, be surrounded by interior insulator, be wound with heating wire at interior insulator, on heating wire, be surrounded by again outer insulator, spray screen at outer insulator.When with heart yearn and heating wire series connection use, because of the cancel out each other magnetic field radiation of heating wire of current opposite in direction, the electric field radiation that produces for heating wire just can be shielded and be eliminated by power ground by the outer field screen of heating wire, the purpose that had both also leaked without electric field radiation without magnetic field radiation when finally reaching heating wire work, can realize a kind of radiationless heating wire of real meaning, another characteristics of this heating wire are can make at the bottom of the thin and cost that the heating wire external diameter does, and are fit to produce the products such as radiationless electric blanket.

Described heating wire comprises heart yearn, interior insulator, heating wire, outer insulator, screen 5 parts, wherein heart yearn is at the middle line of heating wire, material is heating wire or other materials, interior insulator is to adopt to produce at present the insulating material that heating wire generally adopts, heating wire is the heating wire that twines in interior insulator outside, material is heating wire or other materials, outer insulator is to produce the common flame-retardant insulating material that heating wire uses, screen is the conductive coating in the spraying of outer insulator epidermis, material is conductive carbon paste, conductive copper paste, the combination of one or more in the multiple electric conducting material such as conductive silver paste, or directly adopt metal net layer.

By the combination with upper-part, just can realize a kind of radiationless heating wire.

Real meaning of the present utility model is: simple in structure, with low cost, be convenient to produce, radiationless effective.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is a kind of principle schematic of the present utility model.

Mark among the figure: 1, heart yearn, 2, interior insulator, 3, heating wire, 4, outer insulator, 5, screen.

Embodiment:

Below in conjunction with the principle schematic in the accompanying drawing the utility model is further specified:

Accompanying drawing 1 is a kind of principle schematic of irradiation eliminating apparatus of radiationless electric blanket, mainly comprises: heart yearn (1), interior insulator (2), heating wire (3), outer insulator (4), screen (5).

Heart yearn (1) is at the middle line of heating wire in the accompanying drawings, material is heating wire or other materials, interior insulator (2) is to adopt to produce at present the insulating material that heating wire generally adopts, heating wire (3) is the heating wire that twines in interior insulator outside, material is heating wire or other materials, outer insulator (4) is to produce the common flame-retardant insulating material that heating wire uses, screen (5) is the conductive coating in the spraying of outer insulator epidermis, material is conductive carbon paste, conductive copper paste, the combination of one or more in the multiple electric conducting material such as conductive silver paste, or directly adopt metal net layer.

The purpose that the utility model will reach, it is a kind of radiationless radiationless heating wire that leaks, its structure is comprised of 5 parts, being respectively heart yearn (1) is at the middle line of heating wire, material is heating wire or other materials, interior insulator (2) is to adopt to produce at present the insulating material that heating wire generally adopts, heating wire (3) is the heating wire that twines in interior insulator outside, material is heating wire or other materials, outer insulator (4) is to produce the common flame-retardant insulating material that heating wire uses, screen (5) is the conductive coating in the spraying of outer insulator epidermis, material is conductive carbon paste, conductive copper paste, the combination of one or more in the multiple electric conducting material such as conductive silver paste, or directly adopt metal net layer.

In application, as long as heart yearn and the heating wire series connection of certain-length are used, when incoming transport when electricity because of can the cancel out each other magnetic field radiation of heating wire of current opposite in direction, the electric field radiation that produces for heating wire just can be shielded and be eliminated by power ground by the outer field screen of heating wire, finally reach the purpose that when heating wire is worked, had both leaked and also leaked without electric field radiation without magnetic field radiation, can realize a kind of radiationless heating wire of real meaning.

Another characteristics of this heating wire are to make thin and with low cost that the heating wire external diameter does, and the most suitablely are used for producing the product such as radiationless electric blanket.
