Description
The utility model relates to electric blanket class electrothermal article, as: over blanket, pad etc.
Existing first generation electric blanket class articles for use are to coat the rubber and plastic sheath with metal wire to make heating wire, wear to be woven in the blanket, be widely used in warming, but the electromagnetic induction that the alternating magnetic field after the energising produces have adverse effect to the human-body biological effect.Raising along with people's living standard, the second generation metal electric heating line electric blanket that anti-electromagnetic induction or tool far infrared health care function occur, its primary structure is to adopt the bimetallic RVV, or outside heating wire, coat structures such as shielded metal line, demagnetization box and eliminate magnetic flux density, the course of processing complexity of product, and safe effect is not very good.Another electric blanket for increasing function far infrared radiation function, is scribbling the far infrared coating or far IR ceramic fiber is directly being knitted on the blanket face usually on the blanket face.Along with the prolongation of time, the far-infrared powder and the fiber on surface easily come off, and the far infrared radiation effect can not be lasting.
Come out one after another with the electric blanket of non-metallic fibers heating wire processing in recent years, make heating wire, itself have electromagnetic shielding action preferably as carbon fiber filament, but because carbon fiber is more crisp, frangibility, shortcomings such as the easy fluffing of processing are made difficulty of heating wire.The electric blanket of CN94200439.6 patent disclosure, be to be fixed with carbon fiber electrothermal line as the electric heating fuse by directly distributing on the insulation fabricbase, place between blanket surface layer and the blanket bottom, heating wire and external wire joint, by conductive adhesive, the periphery is wrapped with the metal film, and metal film and heating wire and external wire are with high-temp glue outward, are adhered on the terminal block housings.The heating wire that this patent adopts, or a kind of carbon fiber and heating wire cotton, numb, wool blend, or directly use commercially available polyacrylonitrile-based carbon fibre.Though preceding a kind of union twist yarn heating wire cotton, hair, numb blend fibre wherein increased pliability,,, can not twist, otherwise can produce fracture of wire if without gluing or other processing because of the high-modulus of carbon fiber.And this blending heating wire cross sectional shape is circular, and the efficient heat generation area is less, influences the firing rate and the heat efficiency of articles for use.Second kind of heating wire is directly to distribute with carbon fiber wire to be fixed on the insulation fabricbase, has the exposed shortcoming that directly contacts with the blanket face of carbon fiber wire equally with first kind of heating wire, makes carbon fiber wire be vulnerable to lose, and influences the articles for use life-span.And the fixing and large-scale industrial production of this structure inconvenience.The attended operation of the heating wire of this patent and external wire is convenient and firm inadequately in addition.
The purpose of this utility model, it is big to provide a kind of heating wire heating area, and firing rate is fast, and long service life is just quick with side connecting conductor, is convenient to the industrialization processing, has the electric blanket class articles for use of anti-electromagnetic induction and far infrared radiation dual-use function.
The major technique measure that the utility model is taked: space disc is installed with the carbon fiber electric heating heart yearn between blanket surface layer and blanket bottom, and electric heating heart yearn one end is connected with power cord connector by binding post.This electric heating core section is the flattened oval shape, and its skin is that the cross section is the rubber plastics-insulated sheath of flattened oval shape, wherein is coated with the fibre bundle that carbon fiber bundle or carbon fiber mix with far IR ceramic fiber.Binding post is combined by the outer tube that shrinks cutting ferrule and have a rubber and plastic sheath.The contraction cutting ferrule that is installed with the heating core wire terminal penetrates an end of outer tube, and the other end is installed with power supply wiring in the outer tube.Two joints are fixed in the outer tube of chucking.
1K, 3K, 6K, 12K polyacrylonitrile-based carbon fibre long filament that the above-mentioned optional usefulness of electric heating heart yearn is commercially available or the polyacrylonitrile-based carbon fibre that makes up mutually between them are made heart yearn.
Above-mentioned ceramic fibre is selected commercially available PET far-infrared ceramic fibre for use, polypropylene fibre ceramic fibre, polypropylene, polyester far IR ceramic fiber etc.
The mixed proportion of carbon fiber and far IR ceramic fiber is looked the specific requirement of articles for use and is set, and the carbon fiber proportion is at least 50%.
Above-mentioned binding post skin is with heat-shrinkable tube, or the two ends embedding has insulating cement, to strengthen safety, the reliability that binding post connects.
Above-mentioned contraction cutting ferrule and the outer tube that has a rubber and plastic sheath are aluminium matter or copper pipe.
Effect of the present utility model: because the electric heating heart yearn adopts the flat ellipticity sheath covered fiber bundle structure in cross section, area of dissipation is big, the electrothermal efficiency height, and firing rate is fast, and energising instant heating and thermal inertia are little.Area of dissipation increases tens of times than circular metal line, and carbon fiber resistance temperature coefficient is little, and energy-saving effect is obvious, is generally 30%-40%.
The binding post of outer tube combination plier compact form and the sealing of overcoat heat-shrinkable tube make fiber connector and power connection convenient and fast connection, and be reliable.Improve processing efficient.
In addition, because the utility model adopts rubber plastics-insulated sheath carbon coated fibre bundle and far IR ceramic fiber bundle structure, not only make full use of absorption or the damping electromagnetism that carbon fiber itself has and involve the far infrared radiation characteristic, make articles for use can prevent electromagnetic induction and the effect of tool far infrared health care, and overcome coming off and loss of far IR fibre, make health-care effect lasting.Improve useful life.Detect through " the compatible inspection center of electronics industry safety and electric heating ", the anti-electromagnetic induction data of the utility model and anti-electromagnetic induction coaxial electrical hot line are compared as follows:
Under A, the equal length:
These flat carbon fiber electrothermal line 10 circle B=30.8mGS
Anti-electromagnetic induction coaxial electrical hot line 10 circle B=78.3mGS
Under B, the equal-wattage:
