Abstract

The invention discloses a nonradiative heating wire which is composed of a core wire, an internal insulator, a heating wire, an external insulator and a shielding layer and is characterized in that the core wire is coated with the internal insulator; the heating wire is wound around the internal insulator; the heating wire is then coated with the external insulator; and the shielding layer is sprayed on the external insulator. When the core wire and the heating wire are connected in series for use, magnetic field of the heating wire is cancelled out due to opposite directions of current, and electric field generated by the heating wire can be shielded by the shielding layer outside the heating wire and is eliminated through a power ground wire so as to finally achieve the purpose of no magnetic field or electric field leakage during operation of the heating wire. Thus, a real nonradiative heating wire can be realized. Another characteristic of the heating wire is that the external diameter of the heating wire is thin and cost is low, and the heating wire is most suitable for production of products such as a nonradiative electric blanket and the like.

Description

Radiationless heating wire

Technical field

The present invention relates to a kind of radiationless heating wire, belong to heating household appliance technical field.

Background technology

The electric blanket sold in the market line with heating function used is the safeguard measure of unshielded radiation all; when using electric blanket, consumer will, among electromagnetic radiation, because people spread, use the electric blanket time the longest, nearest; 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 first solve the radiation problem of heating wire used in electric blanket.Through investigation and patent retrieval, in existing market, also there is no a kind of radiationless heating wire, so electric blanket on the market has radiation.

Summary of the invention

The problem that there is no radiationless heating wire and existing electric blanket ubiquity hazards of electromagnetic radiation health in order to overcome market, the invention 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 present invention's adopted technical scheme of dealing with problems is: a kind of radiationless heating wire, by heart yearn, interior insulator, heating wire, outer insulator, screen, formed, it is characterized in that: at heart yearn, be surrounded by interior insulator outward, on interior insulator, be wound with heating wire, on heating wire, be surrounded by again outer insulator, on outer insulator, spray screen.When by 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 producing for heating wire just can be shielded and be eliminated by power ground by the outer field screen of heating wire, both the object also having leaked without electric field radiation without magnetic field radiation while finally reaching heating wire work, can realize a kind of radiationless heating wire of real meaning, another feature of this heating wire be can make thin and cost that heating wire external diameter does at the bottom of, be applicable to for producing 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 being wound around 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 is used, 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 invention is: simple in structure, with low cost, be convenient to produce, radiationless effective.

accompanying drawing explanation:

Below in conjunction with drawings and Examples, the present invention is further described.

Accompanying drawing is a kind of principle schematic of the present invention.

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

embodiment:

Below in conjunction with the principle schematic in accompanying drawing, the present invention is further described:

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 being wound around 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 is used, 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 object that the present invention will reach, it is a kind of radiationless radiationless heating wire leaking, 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 being wound around 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 is used, 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 the heart yearn of certain length and heating wire series connection are used, when incoming transport when electricity is because of can the cancel out each other magnetic field radiation of heating wire of current opposite in direction, the electric field radiation producing for heating wire just can be shielded and be eliminated by power ground by the outer field screen of heating wire, finally reach the object that had both leaked and also leaked without electric field radiation without magnetic field radiation when heating wire is worked, can realize a kind of radiationless heating wire of real meaning.

Another feature of this heating wire is can make that heating wire external diameter does thin and with low cost, is the most applicablely used for producing the products such as radiationless electric blanket.
