Abstract
Disclosed is a heating wire which comprises a polyester core column, a heating conducting wire and an inner insulating layer. The heating conducting wire is spirally wound on the outer circumference of the polyester core column, the inner insulating layer is wrapped outside the polyester core column and the heating conducting wire which is a metallic conducting wire, and a temperature sensing conducting wire is wound on the outer circumference of the inner insulating layer. Inner resistance of the temperature sensing conducting wire can be changed when temperature changes, thereby realizing sensing the temperature change according to the change of the inner resistance, and then performing power on-off control of the heating wire. As a good heat conductor, the temperature sensing conductingwire can rapidly transfer locally comparatively higher heat to a position at relatively lower temperature, thereby enabling the heating wire to realize uniform heat generation and reducing possibility of local overheating. The heating wire can be applied inside an electric heating device for meeting the requirement of monitoring temperature.
Description
(1) technical field
The utility model belongs to a kind of heating element, but relates in particular to a kind of heating line of temperature-sensitive.
(2) background technology
In the prior art, the heating line generally by central core, be spirally wound on the heating-wire of central core periphery and be coated on central core and insulating barrier that heating-wire is outer constitutes, described insulating barrier mainly plays the effect of insulation.This heating line is when energising, and the heating-wire of heating line the inside can generate heat, and because of it also has soft characteristic, therefore can use as the heating element in the electric blanket.Its weak point is that this heating wire only has electrically heated simple function, needs to control the heating temp of heating line in use, otherwise can burn out the heating line, causes accidents such as electric leakage, fire.The mode that adopts local temperature to survey mostly in the prior art is come detecting temperature, and then the heating line is carried out power on/off control.As the electric blanket that uses this heating line must load onto temperature tester in electric blanket when carrying out temperature control, and the temperature in the electric blanket is tested, and also need be cooperated the break-make of controlling power supply by a temperature controller.This temperature tester can only be tested local temperature, is difficult to or can not tests the temperature of whole electric blanket fully.
(3) summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of simple in structure, heating evenly, all have temperature sensing lead and the good heating wire of security performance on the whole heater wire of heating line.
The technical scheme in the invention for solving the technical problem is: a kind of heating line, comprise the terylene stem stem, be spirally wound on described terylene stem stem periphery heating-wire and be coated on inner insulating layer outside described terylene stem stem and the described heating-wire, described heating-wire is a plain conductor, and the periphery of described inner insulating layer is wound with a temperature-sensitive lead.
As further improvement of the utility model, also be coated with an external insulation heat-resistant material layer outside described temperature-sensitive lead and the described inner insulating layer.Owing to increased the external insulation heat-resistant material layer, made insulation effect of the present utility model better.
Described temperature-sensitive lead is made by nickel material.
The beneficial effects of the utility model are: the temperature-sensitive lead can change its internal resistance when variations in temperature, the variation that changes in resistance can sense temperature in therefore utilizing, and then the power on/off of heating line controlled; Because this good conductor as heat of temperature-sensitive lead, heat that can the part is higher conducts to the temperature lower fast, makes the utility model heating evenly, has reduced the possibility of local overheating; Because the temperature-sensitive lead is the good conductor of electricity, when heating line local overheating, can melt inner insulating layer again, heating-wire is contacted with the temperature-sensitive lead,, can know whether electric leakage by to the current detecting between temperature-sensitive lead and the heating-wire.In the electric calorifie installation that the utility model can be applicable to monitor temperature.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of its structure of line of generating heat mainly comprises terylene stem stem 1, be spirally wound on described terylene stem stem 1 periphery heating-wire 2 and be coated on inner insulating layer 3 outside described terylene stem stem 1 and the described heating-wire 2, described heating-wire 2 is a plain conductor, the periphery of described inner insulating layer 3 is wound with a temperature-sensitive lead 4, and described temperature-sensitive lead 4 is made by nickel material.Also be coated with an external insulation heat-resistant material layer 5 outside described temperature-sensitive lead 4 and the described inner insulating layer 3.Owing to increased external insulation heat-resistant material layer 5, made insulation effect of the present utility model better.
In the electric calorifie installation that the utility model can be applicable to monitor temperature.
With the electric blanket is example, the utility model is packed in the electric blanket body, and be connected with power supply and temperature control equipment, thereby the temperature to the electric heat mat body is controlled, because power supply input, the heating line that current direction prepares, heating-wire 2 in the heating line generates heat thereupon, along with whole heating line heating, and the resistance value of the temperature-sensitive lead 4 of heating line the inside rises, if the control box that rises in the temperature control equipment is set resistance value, relay is got involved, electric current continues to flow, and temperature rises thereupon.If arrive temperature-sensitive lead 4 resistance values that are set, the circuit in the control box will block, and electric current stops, and the control temperature rises.After body cooled down, the resistance value of temperature-sensitive lead 4 also lowered, and dropped to that the relay in the control box continues to connect intrinsic heating line current heat generation in flow once more again after the resistance value that control box sets.Carry out above-mentioned action repeatedly, make electric blanket inside can keep certain temperature.
Claims (3)
