Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, FIGS. 2 to 9C, and like reference numerals designate like elements in FIGS. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Figure 2 is a perspective view showing a heating element capable of supplying a stable power according to an embodiment of the present invention.

Referring to FIG. 2, a heating element capable of supplying stable power according to an embodiment of the present invention is installed inside the heating body 1 having a heating surface and the heating body 1, and a power supply device (not shown, commercially available). It is provided with a heating wire (2) is generated by the power supplied from a direct current power supply device or a charging module with a built-in secondary battery connected to the power source, the heating wire (2) is a built-in heating wire that is disposed inside the heating body (1) 21 and an outer heating wire 22 which extends integrally with the inner heating wire 21 and is disposed outside the heating main body 1, and has a heating main body 1 corresponding to a boundary point of the outer heating wire. It is comprised so that connection part, such as a soldering welding point, may not be formed in the boundary site | part d.

And the connector 3 connected to a power supply apparatus is directly connected to the edge part of the exterior part heating wire 22. As shown in FIG.

The heat wire 2 applied to the present invention will be described in more detail. Instead, a separate power cable is connected to the heat wire to be supplied with power as in the related art, and the heat wire itself is used as the internal heat wire 21 and the external heat wire 22. It is characterized in that it is composed of a single linear member without a separate connection portion. As such, if a separate power cable is not provided and the external heating wire 21 is integrally formed on the heating wire 2 itself, even if repeated high loads and irregular impact force are applied, there is no structurally weak connection part, so that energization is caused by disconnection or damage. Defects can be prevented beforehand.

And, as described above, if the portion (external heating wire) that performs the function of the power cable for transferring electricity is integrally formed with the internal heating wire 21 for performing the heating action, the external heating wire 22 also naturally generates heat. Although there is a disadvantage in that the action is performed and heated, if the heating temperature of the heating wire is controlled to a temperature similar to the body temperature, there is no fear of causing burns on the feet, and the exterior heating wire 22 also passes through the skin surface of the human body such as the instep. In the case of placement, it is possible to heat the area. In addition, when the power supply device is configured with a charging module (portable rechargeable battery) having a low voltage secondary battery having a use voltage of about 3.7v, the maximum heating temperature is also limited, which does not cause a big problem for safety.

FIG. 3 is an enlarged perspective view of portion B of FIG. 2 for explaining an external portion of a heating element of a heating element capable of supplying stable power according to an embodiment of the present invention.

As shown in FIG. 2, the inner heating wire 21 is arranged and installed in a corrugated structure inside the heat generating body 1, and the outer heating wire portion has both heating wires 22, (as shown in FIG. +) Power line and (-) part that performs the function of power line) are gathered together to form a body by the insulating coating layer (4). At this time, the insulating coating layer 4 is formed with a plurality of heat dissipation holes 41 for effective release of heat. As such, when the heat dissipation hole 41 is formed in the insulating coating layer 4, the temperature of the exterior heating wire 22 may be lowered through heat exchange with air.

4A to 4E are views for explaining a heating wire applied to a heating element capable of supplying stable power according to an embodiment of the present invention.

The heating wire 2 may be selected and applied to various conductive wires having low power consumption and excellent heat generation characteristics, but sufficient stiffness against impact force applied from the bottom during walking and repetitive human load, such as a shoe insole, described later. Since it is important that the outer diameter is composed of a relatively high rigidity linear member to ensure durability, it is preferable to select and apply any one of those shown in Figs. 4A to 4E.

As shown in FIG. 4A, the heating wires 2 are twisted with each other and are covered with a plurality of strands of conductive yarns 23 and conductive yarns 23 formed of metal yarns such as stainless steel wires and iron wires to perform insulation and waterproof functions. It is possible to apply a linear member having a coating layer 24 formed of an insulating resin. This type of heating wire (2) is a stainless wire carrier, having a high tensile strength and conductive iron wire performs the function of the conductive yarn, even if a large tensile force or repeated impact force can be performed stably without any damage.

And, the heating wire 2 is a center yarn 25 disposed in the inner center, a plurality of conductive yarns 23 wound or woven around the center yarn 25, the outside of the conductive yarns as shown in Figure 4b or It is composed of a plurality of reinforcing yarns 26 to be woven, and a coating layer 24 formed of an insulating resin that covers the outside of the reinforcing yarns 26 and performs an insulation function and a waterproof function.

The core yarn 21 is composed of high-strength fiber yarns such as aramid yarn and kebra yarn, which are known to have greater tensile strength than iron wire, so that the conductive yarn 23 does not break even when a large tensile force is applied. That is, since the conductive yarn 23 is wound on the outer circumferential surface of the central yarn 25, the length of the conductive yarn 23 is longer than that of the internal core yarn 25, so when a large tensile force is applied to the hot wire, the tensile yarn is first applied to the relatively short central yarn. (23) can be protected from breakage.

The conductive yarns 23 can be applied by selecting a material having various materials and diameters if electric current can be applied. In FIG. 4B, a fluorine resin or the like can be used for stainless steel wires, copper wires, etc. having a diameter of about 30 to 500 micrometers (μm). Is selected from metal yarns having an insulating coating layer formed thereon. At this time, the number of strands of the conductive yarn 23 may be changed depending on the heat generation capacity, but consists of 5 to 20 strands.

Since the reinforcing yarn 26 should perform the function of a protective coating layer for protecting the conductive yarn once more in consideration of the fact that high loads and irregular impact forces are repeatedly applied from the outside, it has excellent fatigue resistance and at the same time generates heat of the conductive yarn 23. In order to easily transfer the heat to the heat generating body (1) side using a metal material such as stainless steel is formed in a prehistoric diameter of several tens to hundreds of micrometers (㎛) diameter.

In addition, the reinforcement yarn 26 may be applied to a polyamide fiber yarn such as Kebra, Starbod and the like, and a polyethylene fiber yarn such as Dyneema.

In addition, the heating wire 2 is a conductive yarn 23 disposed at the inner center as shown in FIG. 4C, wound or woven around the conductive yarn 23, and having a thermal conductivity to perform a heat transfer function and a protective coating layer. A linear member including a plurality of reinforcing yarns 26, and a coating layer 24 covering the outside of the reinforcing yarns 26 to perform an insulation function and a waterproof function may be applied.

In addition, the hot wire 2 is a core yarn 25 disposed at the inner center as shown in Figure 4d, wound or woven around the center yarn 25, and the thermal conductivity to perform the function of heat transfer function and protective coating layer A plurality of reinforcing yarns 26 formed of a material having a plurality of conductive yarns 23 wound or woven together with the reinforcing yarns 26 and arranged between the reinforcing yarns because the diameter is smaller than that of the reinforcing yarns, and It is possible to apply a linear member including a coating layer 24 which is overlaid on the outside of the reinforcing yarn to perform an insulation function and a waterproof function. At this time, the conductive yarn 23 is applied to the copper wire having a diameter of about 10 to 90 micrometers (㎛), the reinforcement yarn 26 is to apply a stainless steel wire having a diameter of about 100 to 500 micrometers (㎛) Can be.

Meanwhile, as illustrated in FIG. 4E, the heating wire 2 may further include a separate temperature sensing line 27 whose resistance value changes according to a change in temperature. The temperature sensing line 27 is formed of a conductive yarn having a different resistance from that of the conductive yarns 23, and is disposed together with the conductive yarns 23.

The temperature sensing line 27 applies a resistance characteristic value that changes according to a temperature change when the heating wire 2 is heated above a set temperature to a controller (not shown, a control unit provided in the heating element) to supply power applied as a heating wire. To prevent overheating.

That is, if the temperature sensing wire 27 is wound together on the heating wire 2, the resistance value changes when a specific portion of the heating wire is overheated, and according to the change of the resistance value, the controller controls or cuts off the power supply appropriately. Problems such as emergency overheating can be prevented.

In addition, the shape wire alloy 2 is transformed into a shape memorized at a specific transformation temperature (if the shape memory alloy is conductive, it may be replaced with a conductive thread embedded in the heat wire), or electromagnetic waves. It is further provided with an electrostatic yarn (not shown, formed of a fiber yarn containing a conductive material, etc.) and an optical fiber yarn (not shown, meaning a conventional optical fiber yarn for transmitting incident light) for blocking noise and discharging static electricity. can do. The shape memory alloy yarn, the electrostatic yarn, and the optical fiber yarn may be arranged in a form similar to that of the onji sensing wire shown in FIG. 4E.

On the other hand, the heating element capable of supplying a stable power according to the present invention is not shown in detail in the drawing, but the bimetal switch is provided to cut off the power supply when the heating temperature of the heating body is heated above a certain temperature.

5 is a perspective view illustrating a built-in portion of a heating element of a heating element capable of supplying stable power according to an embodiment of the present invention. In FIG. 5, an enlarged portion is an enlarged view of a cross section of a C portion and a D portion.

The heating wire does not cause a big problem even if the heating wire is composed of the internal heating wire 21 and the external heating wire 22 having the same structure as described above, but the internal heating wire 21 is not heated. ) Is preferably formed of a structure having a larger electrical resistance value than the exterior heating wire 22 or formed of a material having a large electrical resistance value (a material having low electrical conductivity).

For example, as shown in the enlarged portion D of FIG. 5, the number of strands of the conductive yarns 23 wound around the central yarn 25 is equal to the number of strands of the conductive yarns 23 of the exterior heater wires 22. It is configured to have a smaller quantity compared to (see section C enlarged), or some strands of the conductive yarns 23 of the built-in heating wire 21 are cut to have a disconnected structure. As shown in FIG. 5, when the number of conductive yarn strands of the inner portion heating wire 21 is small or partially cut, the outer portion heating wire 22 may function as a power cable without being easily heated because a relatively small resistance is applied.
