Definitions

  • the present invention relates to a control and monitoring device for Prevention of overheating in flexible, textile surface heating elements, the at least two opposing contact conductors made of electrically conductive, uninsulated fibers or wires, between which several heating conductors extend, which are electrically connected to the contactors.
  • From DE 4 101 290 and DE 19 831 574 are textile surface heating with at least two opposing contact strips of electrically conductive, uninsulated fibers or wires, between which more of an electrical Resistance material existing uninsulated heating conductors run, known.
  • This type of surface heating elements are used primarily for seat heaters Used motor vehicles. Due to chemical and mechanical influences Like water, salt and movement on the seat, both the heating conductors and the Over time the contact ladder was attacked and destroyed locally.
  • the mechanism of destruction is such that either the leaders of the Break contact strips by constant bending and compression and thus the Cross section of the contact strip tapers at the kink or the contact conductors are chemically attacked and decompose or the contact resistance from heat conductor to the contact conductor increases, so that increased heat output is produced. Also, the installation of a temperature sensor can be at the above Heating elements do not exclude the thermal problems on the contact conductors.
  • a monitoring device of to develop the aforementioned type which prevents the heating element to or near the contact conductor gets so hot that the allowable thermal Limit temperature of the surrounding materials is exceeded.
  • this object is achieved by a control and Monitoring device to prevent overheating in flexible, textile Surface heating elements consisting of at least two opposite ones Contact conductors consist of electrically conductive, uninsulated fibers or wires, between which several heating conductors extend, which with the contact conductors electrically are conductively connected, with an additional conductor is placed over the heating element and with a Evaluation unit is coupled to the with a current-voltage source for the heating conductors works together to prevent overheating.
  • the additional conductor carries an insulation made of plastic or paint, which at intended use does not melt and thus prevents the Heat conductor and the additional conductor get electrical contact.
  • a detection conductor as additional conductor two or monitored multiple contact strips, this from a contact strip along the Heating conductor is led to the next contact strip.
  • claim 2 allow in particular the safe operation of Heating elements with metallic contact conductors and interconnected Heating conductors made of carbon fibers. Because these high temperatures are at fault locations at the Due to the high melting temperature of the Carbon fibers cause significant damage.
  • the heating element according to Fig. 1 consists of a two-part textile Surface heating element 4, the upper part of a wavy heating conductor and whose lower part have a network-arranged heating conductor.
  • the heating conductors are 8.1, 8.2 as CarbonMapleiter and the Additional conductor 1 formed as a rectilinear detection conductor.
  • This arrangement but is not mandatory, but it can be modified by case by metallic heating conductors or other heating conductor materials.
  • the additional ladder in However, they should be routed through the heating element at any angle remain outside the temperature sensing range, which in this example is lower terminal end of the contact conductor indicated by a temperature sensor 5 Is.
  • a section of the heating element is shown in cross-sectional shape.
  • the contact conductors 3 and the carbon heating conductors 8 are present as filaments.
  • the salt conductor consists of a detection conductor 1 in its core of a steel filament. 7 which is provided with a coating material of a melt insulation 6.
  • the monitoring device according to the invention thus consists of the additional conductors in the form of detection conductors 1 and the evaluation circuit 11. It is therefore relatively easy to introduce in a heating element and hardly causes additional costs. Due to its simple structure is the inventive Monitoring device is immune to interference and provides throughout the entire Lifetime of a panel heater safe protection against excessive Warming.
