Definitions

  • the invention relates to a thermal blanket or a heating pad with a flexible electrical heating conductor, which is embedded in an insulating compound and is arranged in a sheet shape in a shell made of a textile fabric.
  • Heating blankets or heating cushions are provided in a known manner with a heating conductor in the form of an electrical resistance wire surrounded by an insulation mass, which depending on the type and size of the blanket or cushion is serpentine or meandering in the envelope or an intermediate lining is arranged and fixed.
  • Two methods are used for their production. In one manufacturing method, the two surface parts of the shell made of textile fabric are woven from one piece with the formation of parallel channels, into which the resistance wire then has to be drawn in a laborious manner by two people in a meandering manner.
  • the resistance wire is on a lower one Surface part of the textile fabric or intermediate lining fixed in a snake shape by means of needles or the like and the other surface part placed on and thermally welded to the lower surface part.
  • a serpentine laying of the resistance wire by hand is required in a complicated and costly manner.
  • Both versions also have the disadvantage that the resistance wire can be felt despite the incorporation of an intermediate lining made of fleece, fiber mats, foam or the like, and is perceived as annoying when using the heat blanket or the heat cushion.
  • the invention has for its object to form a heat blanket or a heat cushion of the generic type such that the meandering drawing or laying of the electrical resistance wire by hand is omitted and the heating conductor is no longer noticeable.
  • a flexible surface heating conductor made of an electrically conductive silicone rubber, which is provided on each of two opposite edges with a flexible metallic conductor strip and is covered with an insulation layer.
  • this flat heating conductor which has the shape and the flexibility of a thin rubber fabric, in the heat blanket or the heating cushion initially has the advantage that a heating conductor is practically no longer noticeable.
  • the rubber-like surface heating conductor which is flexible in all directions, adapts to any position and shape that is given to the blanket or pillow in use.
  • the warming blanket or the warming pillow is therefore much smoother and more pleasant to use.
  • Another advantage is that the surface heating conductor is much more uniform Heat distribution and transfer causes.
  • the manufacture of the heat blankets or heat cushions is considerably simplified, since the surface heating conductor in its skin-like shape can only be inserted; pulling in or laying in meandering form is therefore not necessary.
  • Silicone rubber contains as a conductive component special carbon blacks which, in conjunction with the silicone polymers, take care of the conductivity mechanism based on the electron tunnel effect and type designed for power from about 30 to 130 watts, ie from about 25 to 100 watts / m. However, depending on the requirements, other values can also be used.
  • the insulation layer required for the surface heating conductor can be applied in various ways. For example, a film made of an electrically insulating silicone rubber can be glued on using a silicon conductor. However, it is also possible to apply and vulcanize an appropriate silicone compound by dipping, spraying or knife coating. There are also numerous options for attaching the conductor strips, which consist, for example, of a wire strand made of copper or another suitable metal. The conductor strips are preferably connected to the vulcanized electrically conductive silicone rubber compound of the surface heating conductor or attached by means of an electrically conductive silicone rubber adhesive compound. An intermediate lining, for example made of fleece, fiber mats, foam or the like, can also be used between the insulation layer and the shell made of textile fabric.
  • the entire production can be carried out in one continuous pass, the layers in question being applied by immersion or spraying or by sandwich-like assembly of lamellate-like preliminary products.
  • a thermal blanket 1 designed according to the invention is shown, to which a surface heating conductor 2 is assigned, as described above.
  • a surface heating conductor 2 is assigned, as described above.
  • This is on two opposite edges each with a flexible conductor strip 3, e.g. a copper wire strand, which are electrically conductively connected to the electrically conductive coating of silicone rubber of the surface heating conductor 2 and evenly distribute the current conducted via the connecting lines 4.
  • An insulation layer 6 e.g. in the form of foils made of insulating silicone rubber is applied by means of an adhesive 5 to the two surfaces of the surface heating conductor 2, the conductor strips 3 and the edges also being insulated all round.
  • the actual covering 7 of the blanket or pillow is arranged above or below the insulation layer 6, if necessary with the interposition of an intermediate lining 8, the edge of which protrudes somewhat from the surface heating conductor 2, so that this edge zone also accommodates the power connection lines 4, Thermal switch and the like (not shown) can be used.
