Now only by way of example with reference to accompanying schematic figure explanation some embodiments of the present invention.

In the accompanying drawing, Fig. 1 is the schematic cross section by the part goods of one embodiment of the invention;

Fig. 2,3 and 4 is schematic diagrames that the present invention is applied to sleeping bag, has shown the wiring configuration mode that some are possible;

Fig. 5 is that the present invention is applied to the schematic diagram of animal with felt;

Fig. 6 is the schematic diagram that the present invention is applied to life vest.

Referring now to Fig. 1,, this is the structure that (in various modes) can be used for the electrothermal goods of sleeping bag, animal usefulness felt, clothing etc.These warming goods comprise for example aluminium plating fabric of the thermal reflective material layer 10(that can ventilate), insulation material (for example clogging fiberfill or fine hair that quilt is used) the ground floor 12a that makes and the woven lining 14 of innermost layer.Resistive heater 16 is placed between the heat-reflecting layer 10 and the first heat-insulation layer 12a, can stitch or otherwise be fixed on layer 10 or the layer 12a.As the optional practice, can establish outermost cover 18, preferably the waterproof material that can ventilate Govetex(trade mark for example) or the Sympatex(trade mark) make, and between heat-reflecting layer 10 and cover 18, can establish the second heat-insulation layer 12b.

Lining 14 also can be made by heat-reflecting material.The heat reflectivity material is when having only an aluminium plating fabric, and layer 10 and layer 14 one side of aluminizing are (promptly being down in Fig. 1) inwardly all.

Desirable especially insulation material is the Trispace(trade mark), not only heat-insulating property is good but also volume is little for it, and is in light weight.Each heat-insulation layer 12a, 12b can comprise one or more layers this material.

Fig. 2 is the schematic diagram with sleeping bag of said structure, and sleeping bag is launching, and can see the configuration mode of heater strip 16.Heater strip 16 traverses between the top 20a of bag 20 and the bottom 20b with the snake shape or the mode of spiraling and disposes.One end of heater strip 16 is connected on the connector 24 through series connection fuse 22 on the line at bag 20 tops.The other end of heater strip 16 is placed in the bottom of bag 20, is connected on the connector 24 by low resistance cable 26.

Heater strip 16 recommendable materials are that resistance is the copper wire that insulating covering is arranged of 138 Europe/km, and in the case, its suitable length is 26.67 meters, thereby total resistance value is 3.68 Europe.This is to prepare to be encouraged by 12 volts (nominal value) power supplys, for example battery of motor vehicles or portable battery, and preferably capacity is the nickel-cadmium cell of 20-30 ampere-hour.Desirable especially heater strip is the copper litz wire of 0.14 millimeter of diameter with waterproof fireproofing insulating material foreskin (electronic computer used usually that a kind of).This line can highly bear deflection, stretching or knotting and not damage, and is efflorescence and be unlikely fusion or form drop when overheated.

Low resistance cable 26 is 24 strands of diplocardia polyvinyl chloride insulating flexible cables that 0.75 millimeter multicore copper stranded conductor is formed preferably.

The sort of cable configurations mode shown in the figure is guaranteed whole sleeping bag homogeneous heating.If all adopt resistance wires, then the not high meeting of voltage of adding DC power supply of the pressure drop in the resistance wire causes the bottom of sleeping bag colder than the top.

Fig. 3 is similar configuration mode, just parallel line (total length of heating element is generally 67 to 85 meters) is separately adopted in sleeping bag top and bottom, then two circuits are adopted on each limit of sleeping bag in the configuration mode of Fig. 4, the heating element total length is 130 to 170 meters, in the case, four circuits all are connected in parallel.The structure of the length of heating line and configuration mode and sleeping bag can be by concrete purposes change.Circuit temperature in short-term is higher, but power consumption is big, when adopting two or more parallel line then the efficiency of heating surface than the height of the single circuit of equivalent length.The structure of sleeping bag, the particularly number of plies of heat-insulation layer 12a, 12b can be changed according to the harsh situation of sleeping bag environment for use.

Experiment shows that NI-G (Ni-Cd) battery that weighs 20 ampere-hours (Ah) of 3 pounds (1.36 kilograms) can make sleeping bag remain on people's body temperature level at least in two hours.It is effective especially when this makes the present invention be used for sleeping bag to mountain-climbing ambulance corps, lifeboat and other situation that need handle low temperature.When adopting battery, battery pack preferably is placed in the sleeping bag, makes it not be subjected to the influence of low temperature.
