Definitions

  • the present invention relates to woven electric heaters, and may be used for heating/warming car seats, and arm-chairs, in warming pads, bed-pans, and other electric heater devices performing surface heat emission.
  • a woven heating element for instance, US Patent No. 2,345,300; 1941
  • an electric current-conductive strand spirally wound over a soft core from insulating material is worked in transverse (zigzag) directions into the fabric comprising insulating yarns.
  • a spiral winding of an electric current-carrying strand over a soft core substantially reduces the total length of the heating element, and thus increases the space between separate heating slivers, effecting uneven heating of individual portions thereof. Also, the heating element becomes too thick and, for that reason, rather rigid for bending. And this complicates the weaving process of the loom.
  • a woven electric heater comprising warp and weft from electrical insulating material, that are interwoven with formation of background and selvage; also weft from electric current-conductive material worked into background, with formation of heating portions and insulating strips; also current-conducting strand worked into selvage along the warp yarns, which come in contact with yarns' ends of the weft from electric current-conductive material at every heating portion (for instance, US Patent No. 3,425,020; 1969).
  • Heating portions and insulating strips of the said woven electric heater are executed by the same type of interweaving technique, that is linen.
  • fabric density on background and selvage is different. Density on background decreases in selvage.
  • the rarefied selvage texture brings down, in its turn, the reliability of contact between the current-carrying strand and the electric current-conductive weft.
  • a woven electric heater comprising warp and weft from electrical insulating material, that are interwoven with formation of background and selvage; also comprising weft from electric current-conductive material worked into background, with formation of heating portions; also current-carrying strand worked into selvage along the warp yarns, which come in contact with yarns' ends of weft from electric current-conductive material at every heating portion;
  • the weft yarn from electric-conductive material has a complete insulation cover
  • the warp yarn is produced from material having 0,01-5% longitudinal shrinkage at 25-120 degrees C
  • the weft yarn is manufactured from material retaining geometrical patterns in heating conditions, and contact between the current-carrying strand and the weft yarn from current-conductive material is secured by commutative elements fixed between the heating portions on selvage.
  • Background and selvage are performed by different interweaving technique; between every two adjacent weft yarns from electric-conductive material, at least four weft yarns from insulating material are worked into the heating portion in such a way that in rapport of background interweaving, the two adjacent weft yarns from electrical insulating material are overlapped by the same warp yarns, while in rapport of selvage interweaving every weft yarn from electrical insulating material is overlapped by a single warp yarn.
  • poly-ether strand stabilized at 150-180 degrees C it is preferable to use poly-ether strand stabilized at 150-180 degrees C as the weft yarn from electrical insulating material, and employ instabilized poly-ether strand as the warp yarn.
  • the complete insulating cover of the weft yarn from electric current-conductive material is 0.15-0.45 mm thick.
  • the complete insulation cover of the weft yarn from electric current-conductive material has fibrous texture, with a multitude of extremely thin insulation material fibres embracing and also fixed to the weft yarn by means of insulating lisle thread.
  • the woven electric heater comprises warp 1 (Fig. 1) and weft 2 from electrical insulating material, interwoven with formation of background 3 and selvage 4.
  • warp 1 Fig. 1
  • weft 2 from electrical insulating material
  • background 3 weft 5 from electric current-conducting material
  • weft 5 from electric current-conducting material
  • the described embodiment contains two portions 6.
  • selvage 4 along warp 1 yarns current-carrying strand 8 is incorporated.
  • Weft 5 yarn from electric current-conductive material and current-carrying strand 8 have complete insulation cover, which thickness is within 0.15-0.45mm.
  • Warp 1 yarn is manufactured from material having length shrinkage within 0.01-5% at 25 to 120 degrees C; weft 2 yarn is manufactured from material retaining its geometrical pattern in heating conditions.
  • Yet another embodiment is possible with employment of poly-ether strand stabilized at 150-180 degrees C, as weft 2 yarn, and use of instabilized polyether strand as warp 1 yarn.
  • Element 9 is represented by a clip (Fig.2) from brass and copper type electric current-conducting low-resistance material fixed on selvage 4, preferably between heating portions 6. Every commutative element 9 has electrical connection with two insulation free ends of weft 5 made of current-conductive yarn of adjacent heating portions 6, and with insulation free portion of current-carrying strand 8. Connections are arranged in such manner that electromagnetic fields evolved by current lead, are respectively compensated.
  • Fig. 2 also illustrates end 10 of current-carrying flex 11 and brazed joint 12 fixing the electric contact.
  • background 3 (Fig. 3, 4) and selvage 4 are performed by different interweaving technique.
  • two adjacent yarns of weft 2 from electric current-insulating material are overlapped by the same yarns of warp 1.
  • one yarn of weft 2 if overlapped by one yarn of warp 1.
  • Fabric density on weft in background is within 4-15 cm ⁇ 1.
  • weft 5 yarn from electric current-conductive material is worked into fabric by linen interweaving.
  • Other alternatives of incorporation are possible, for instance, serge interweaving, warp reps 2/2.
  • At least two yarns of weft 2 (Fig.5,6) can be interspersed between weft 2 yarns worked in pairs, with identical interweaving in background 3 and selvage 4.
  • the woven electric heater operates as follows.
