Specifically, the warp portion 100 may be formed of a wire having a diameter of about 0.035 mm to about 0.1 mm. The warp portion 100 may be constituted by 1 filament to 16 filaments. When the warp portion 100 is formed of the spiral yarn or the ply yarn, the warp portion 100 may be provided at about 200 TPM (twist per meter) to about 1,400 TMP and thus be adjustable in density. The single yarn refers to a yarn formed of one filament made to be twisted in only one direction. The spiral yarn refers to a yarn made by twisting other yarns around the yarn in a spiral shape. The ply yarn refers to a yarn made to be twisted by adding two or more filaments of the single yarn.
The warp portion 100 may use any material to implement the above-described function. The warp portion 100 may be a metal heating a wire to implement the above-described function. The warp portion 100 may be an electrically conductive hot wire coated with a synthetic resin to implement the above-described function. The warp portion 100 may be an electrically conductive hot wire extruded from a synthetic resin to implement the above-described function. More specifically, as an example of the material of the warp portion 100, stainless steel (STS) may be used. As an example of the material of the warp portion 100, lightweight stainless steel may be used. As an example of the material of the warp portion 100, stainless steel having high corrosion resistance may be used. As an example of the material of the warp portion 100, stainless steel having highly flexible may be used. As an example of the material of the warp portion 100, stainless steel having high durability may be used.
The warp portion 100 may be constituted by about 100 wires per inch to about 700 wires per inch. The warp portion 100 may adjust a heat-generation temperature of the planar heater according to an embodiment.
The planar heater according to an embodiment may be provided with the weft portion 200. The weft portion 200 is disposed in a horizontal direction in the planar heater according to an embodiment. The weft portion 200 may be connected to a portion of the warp portion 100. The weft portion 200 may be formed of a wire having an electrical resistance coefficient that is equal to or less than that of the wire of the warp portion 100. For example, when the weft portion 200 and the warp portion 100 have the same electric resistance coefficient, the wire of the weft portion 200 may increase in thickness so that the electrical resistance of the weft portion 200 is less than that of the warp portion 100. The thickness of the wire may correspond to a cross-sectional area of the wire. This is done for a reason in which current rapidly flows through the weft portion 200 to generate uniform heat as a whole.
The weft portion 200 may be constituted by a single yarn, a spiral yarn, or a ply yarn for elasticity and strength. Specifically, the weft portion 200 may be formed of a wire having a diameter of about 0.035 mm to about 0.1 mm. The weft portion 200 may be constituted by 1 filament to 4 filaments. When the weft portion 200 is formed of the spiral yarn or the ply yarn, the weft portion 200 may be provided at about 200 TPM (twist per meter) to about 1,400 TMP and thus be adjustable in density.
The wire constituting the weft portion 200 may be made of a material having a lower electrical resistance coefficient than that of the warp portion 100. When the material of the wire constituting the weft portion 200 is the same as the material of the wire constituting the warp portion 100, the thickness of the wire of the weft portion 200 may be adjusted differently. The thickness of the wire may correspond to a cross-sectional area of the wire.
In the case of adjusting the electrical resistance by changing the material of the wire, the weft portion 200 may use a conductive wire so that current flows rapidly as a whole.
For example, when the warp portion 100 is formed of a stainless steel wire, the weft portion 200 may be formed of a conductive wire such as copper or nickel, which is a material having an electrical resistance coefficient less than that of stainless steel.
In the weft portion 200, the current may rapidly flow when compared to the warp portion 100. The weft portion 200 may enable uniform heat generation as a whole. The weft portion 200 may serve as a heater when a heat-generation material is used.
The thickness of the wire constituting the weft portion 200 may be greater (wider) than that of the wire of the warp portion 100. The thickness of the wire may correspond to a cross-sectional area of the wire. If the thickness of the wire constituting the weft portion 200 is greater than that of the wire constituting the warp portion 100, the current flow in the weft portion 200 may be faster. The weft portion 200 may enable uniform heat generation as a whole.
The weft portion 200 may further include a non-conductive material. The weft portion 200 may be made of polyethylene, glass fiber, rubber, or silicone. Polyethylene may be used as an example of the non-conductive material of the weft portion 200. A glass fiber may be used as an example of the non-conductive material of the weft portion 200. Rubber may be used as an example of the non-conductive material of the weft portion 200. Silicon may be used as an example of the non-conductive material of the weft portion 200. The weft portion 200 may include at least one or more of polyethylene, glass fiber, rubber, and silicone. When the different wefts 200 overlap each other, the cross-sectional area may increase. When the different weft portions 200 overlap, the resistance may be reduced. When the resistance of the weft portion 200 is reduced, the heat generation may be uniform. Therefore, the weft portion 200 may include a non-conductive material.
The weft portion 200 may be constituted by about 100 wires per inch to about 700 wires per inch. The weft portion 200 may adjust a heat-generation temperature of the planar heater according to an embodiment.
The module portion 300 connected to the warp portion 100 may be provided. The module portion 300 may include an electrode member. A power connection terminal and the like may be attached to the electrode member.
The module portion 300 may be connected to the warp portion 100. The module portion 300 may supply power. The module portion 300 may allow current to flow through the warp portion 100.
The configuration of the module portion 300 may be variously changed in design according to the purpose to which the use of the planar heater, for clothes, heating devices, home appliances, livestock equipment, etc. is applied.
The planar heater according to an embodiment may have a unit pattern constituted the predetermined warp and weft yarns as illustrated in Figs. 1 to 8. The warp disposed at each of both edges of the unit pattern may be formed of the ply yarn.
Due to the configuration of the ply yarn, there is an advantage in that unwinding does not occur at the edges.
The configuration of the warp portion 100 except for the edges of the unit pattern may be variously changed in design according to the purpose to which it is applied. The configuration of the warp portion 100 except for the edges in the unit pattern may be effectively disposed as illustrated in Figs. 1, 3, 5, and 7.
Hereinafter, an operation of the planar heater according to an embodiment will be described.
First, power may be supplied to the planar heater according to an embodiment. When the power is supplied, current may flow through the electrode member of the module portion 300.
The warp portion 100 may be connected to one side of the module portion 300. The current may be transmitted through the wire of the warp portion 100 to generate heat. The current may be transmitted to the weft portion 200 through one side of the wire of the warp portion 100. When the current is transmitted to the weft portion 200, heat may be generated simultaneously with the flow of the current.
