Abstract
The utility model relates to a PTC automatic temperature limiting electric heating blanket, which is composed of PTC automatic temperature limiting electric heating wires, heat insulation cloth, a junction box, a controller, etc. The PTC automatic temperature limiting electric heating wires are formed by that a heating body is formed by two parallel electric core wires which are coated with PTC materials outside; the outermost part of the heating body is coated with a layer of insulating sheath. The electric core wires are formed by more than one (contains one) wire which is wound on chemical fibre spirally. A heating belt is used for adapting a heated system. The heated system is used for the heating belt in traditional constant power electric blankets. The utility model can not be burnt out by self heat never and heats in constant temperature. The utility model has the advantages of automatic temperature control, overheating preventing, electric energy saving, safe utilization, comfortable use, better bend resistance performance, and better pull resistance strength.
Description
PTC belongs to electrothermal piece (HO5B) from limitting warm electric blanket
Electric blanket is quite universal as the domestic electric heating product, and present electric blanket experience is regenerated for several times and improved, and its reliability and fail safe are all improved a lot.But the electric blanket of popularizing all uses permanent power heater at present, its heating power is constant, be not subjected to the influence of ambient temperature, so in use, this electric blanket exists the hidden danger that produces danger under the abnormalities such as all unreliable factors, particularly localized hyperthermia and folding use and is not solved.
The purpose of this utility model is at the problems referred to above, adopts new material, new technology, provides a kind of New PTC from limitting warm electric blanket, has fundamentally solved localized hyperthermia and folded to use to produce dangerous hidden danger.
The utility model electric blanket has adopted a kind of new material PTC from limitting warm heating wire as the heating line, the resistivity of this line has very high positive temperature coefficient, and promptly along with the rising of temperature, the resistance of PTC heating wire increases, the corresponding decline of power reaches the purpose of automatic limit temperature.The following formation of the utility model: have PTC from limitting temperature heating wire 3, heat-preservation clothing material 4, terminal box 2, controller 1 and electrical connector (can be included in the controller), it is characterized in that PTC is from limitting warm heating wire 3 by two parallel electrically conductive heart yearns 9, outside it, coat the heater 6 that ptc material forms, outermost coated insulation sheath 5 is formed, and every conductive core line 9 is to adopt plain conductor 8 helically coilings that (contain) more than on internal core wire 7.Internal core wire 7 can adopt chemical fibre.Ptc material is the electrothermal conductor that resistivity has very high positive temperature coefficient, generally adopts resistivity to have the conducting polymer composite complex of very high positive temperature coefficient.

Embodiment:
Two parallel electrically conductive heart yearns 9, outer extrusion molding ptc material 6 promptly are the conducting polymer composite complexs (formation heater) that resistivity has very high positive temperature coefficient, and the plastic one deck insulating sleeve 5 of outermost constitutes PTC thus from limitting warm heating wire.Wherein every conductive core line 9 usefulness one wires 8 helically coilings are on chemical fibre 7.Chemical fibre 7 adopts polyster fibre, nylon yarn etc.Metal wire 8 can adopt zinc-plated copper free wire, constantan wire, brass wire etc.PTC self-temperature-limiting heating strip outsourcing heat-preservation clothing material 4 is loaded onto electrical connectors such as terminal box 2, controller 1 and power line, latch and is constituted PTC from limitting warm electric blanket.
The course of work: energized, the electric current via controller forms loop (parallel-connection structure) by the metal wire of the conductive core line heater 6 (ptc material) of cross-over connection between two conductive core lines of flowing through to another conductive core line metal wire.Electric energy heats up heater.Because heater has the PTC feature, its resistance can be made nonlinear change with temperature, thereby adjusts thermal output automatically.Heat conducts heat to the lower system that is heated (heat-preservation clothing material) of temperature through the insulation sheath.When the heated object temperature was low, heat transfer rate was fast, and power is bigger, and when the heated object temperature was higher, heat transfer rate was slow, and power is less.So just realized automatic limit temperature heat transfer.Traditional permanent power electric blanket is not subjected to the heated object Temperature Influence, and almost constant power is provided all the time.Be to allow the PTC heating tape adapt to be heated system from the above, and permanent power mode of heating is to be heated system to deacclimatize the heating line from limitting warm mode of heating.
Advantage of the present utility model:
1. even this electric blanket is under the good situation of insulation, the heat that also will not be sent by self burns, Therefore use fool proof. 2. heating wire has the function of automatic regulating power, is a good constant temperature Therefore heater uses very comfortable. 3. because the conductive core line of PTC line with heating function has adopted helically coiling Metal wire is so the bending resistance folding endurance is fine; Owing to use high strength chemistry fiber to make internal core wire, so tensile strength Very big.
Claims (3)
