First, the covering member 100 using the planar heating element of the present invention is provided with a planar heating element 200. The planar heating element 200 is configured in a network (mesh) structure by supplying and weaving wires with warp and weft.

Here, the covering member is not limited to shoes, gloves, clothing, etc., and any material capable of covering or protecting a human body may be used.

The planar heating element 200 enables heat generation of the covering member 100 using the planar heating element of the present invention.

The first wire part 310 is configured in a mesh shape by supplying and weaving wires in warp and weft yarns, and serves to generate heat from the planar heating element by receiving power.

The wire constituting the first wire part 310 may be a material used as a metal heating wire or a heating wire material obtained by coating or extruding an electrically conductive heating wire with a synthetic resin.

As an example of the material of the first wire part 310, stainless steel (STS) having high weight reduction, corrosion resistance, flexibility, and durability may be used.

The first wire part 310 may adjust the density of the mesh (network) structure, thereby controlling the current distribution of the entire plane.

It is preferable to use a wire having a diameter of 0.1 to 1 mm for the first wire part 310 in consideration of the amount of heat generated and prevention of deterioration.

A coating layer 360 that coats the first wire part 310 may be further included, and the coating layer 360 may be made of silicone, epoxy, or urethane for washing, durability, corrosion resistance, and insulation effect.

The coating layer 460 preferably contains 0.5 to 10 parts by weight of metal powder or ceramic powder based on 100 parts by weight of silicone, epoxy or urethane.

The pattern portion 420 has an electrical resistance lower than that of the first wire portion 410. This is to deliver a current that quickly flows through the pattern part 420 to the first wire part 410 to generate uniform heat generation as a whole.

The electric resistance may be adjusted by using a conductive paste constituting the pattern portion 420 as a conductive paste containing a material having a lower electric resistance than the first wire portion 410.

Compared to the stainless steel constituting the first wire part 310, the pattern part 420 is patterned with a conductive paste such as copper or nickel, which has a low electrical resistance, so that the flow of current is faster to generate uniform heat generation as a whole. Make this possible.

The pattern unit 420 may allow a uniform heat generation as a whole by making the current flow faster, and may also serve as a heating element when a heat generating material is used.

division Branch 1 Branch 2 Branch 3 Branch 4 Branch 5 Branch 6 Branch 7 Branch 8 Branch 9 Branch 10 Comparative Example 2 40.1℃ 43.5 38.1℃ 52.3℃ 51.0℃ 45.6℃ 44.8℃ 39.8℃ 41.5℃ 55.1℃ Example 5 60.0℃ 60.5℃ 60.2℃ 60.3℃ 59.7℃ 59.6℃ 60.1℃ 59.6℃ 60.5℃ 59.5℃ Example 6 59.9℃ 60.0℃ 60.3℃ 60.5℃ 60.2℃ 59.7℃ 59.8℃ 60.1℃ 60.0℃ 59.5℃ Example 7 60.1℃ 60.2℃ 60.0℃ 60.0℃ 59.8℃ 60.1℃ 60.4℃ 59.6℃ 60.3℃ 59.5℃ Example 8 60.2℃ 59.6℃ 59.7℃ 60.3℃ 59.8℃ 60.0℃ 59.9℃ 60.1℃ 60.1℃ 60.3℃ Example 9 56.2℃ 61.3℃ 63.0℃ 60.2℃ 57.5℃ 62.1℃ 58.8℃ 61.2℃ 59.0℃ 60.7℃

As shown in Table 3 above, it can be seen that as the tungsten size decreases, a uniform heating effect is exhibited as in Examples 5 to 8. When the size of tungsten is more than 500 nm, there is a problem that a uniform heating effect cannot be seen.

Examples 5 to 8 show similar exothermic temperatures. However, in manufacturing tungsten in a small size, the cost is excessive, so it is preferable to manufacture the coating layer in the same size as in Example 8.
