Description

Temperaturregler mit besonderer elektrischer Beheizung für elektrisch beheizte Geräte Es sind Thermostaten bekannt, bei denen das temperaturempfindliche Organ durch Leitung oder Strahlung beheizt wird. Als Heizleiter wird durchweg Material verwendet, dessen Temperaturkoeffizient sehr gering ist, so daß sich der Widerstand der Reglerbeheizung auch mit zunehmender Erwärmung nicht ändert.Temperature regulator with special electrical heating for electrical heated devices There are known thermostats in which the temperature-sensitive Organ is heated by conduction or radiation. Material is used throughout as the heating conductor used, the temperature coefficient of which is very low, so that the resistance the controller heating does not change even with increasing heating.

Bei Wärmezeitauslösern ist auch eine Anordnung bekannt, bei der ein Ausdehnungskörper beliebiger Art, der durch den Stromdurchgang ohne besondere Hilfswicklung unmittelbar erwärmt wird, eine zusätzliche mittelbare Erwärmung durch einen besonderen parallel geschalteten Heizkörper erhält. Dieser besondere Heizkörper ist mit einem Widerstandsmaterial mit starkem positivem Temperaturkoeffizienten ausgerüstet, um zu verhindern, daß bei starkem Überstrom ein Durchbrennen dieser zusätzlichen B'eheizungsanordnung eintritt.In the case of thermal time releases, an arrangement is also known in which a Expansion body of any kind that passes through the current without a special auxiliary winding is heated directly, an additional indirect heating by a special one radiator connected in parallel. This particular radiator comes with a Resistance material equipped with strong positive temperature coefficient to to prevent this additional heating arrangement from burning out in the event of a strong overcurrent entry.

Neuerdings sind elektrisch beheizte Geräte geschaffen worden; äeren Widerstandsmaterial einen positiven Temperaturkoeffizienten hat, so daß der Widerstand des Hauptstromkreises bei zunehmender Erwärmung ebenfalls zunimmt. Wird zur Steuerung des Gerätes ein beheizter Regler verwendet, dessen Beheizung wie bisher aus einem Material mit sehr geringem Temperaturkoeffizienten besteht, so tritt der Übelstand ein, daß das Verhältnis zwischen Reglerwiderstand und Hauptwiderstand sich verkleinert. Der Regler bekommt also bei zunehmender Temperatur infolge Sinkens der Stromstärke durch Zunahme des Hauptwiderstandes eine im Quadrat der Stromstärkenänderung verringerte Beheizung, da derReglerheizwiderstand konstant bleibt.Recently, electrically heated devices have been created; aeren Resistance material has a positive temperature coefficient, so that the resistance of the main circuit also increases as the temperature increases. Becomes a control of the device uses a heated controller, the heating of which, as before, consists of a If there is material with a very low temperature coefficient, the problem occurs one that the ratio between controller resistance and main resistance is reduced. So the controller gets with increasing temperature due to a decrease in the current strength by increasing the main resistance, the square of the change in the current intensity was reduced Heating, as the controller heating resistance remains constant.

Erfindungsgedanke ist, für die Reglerbeheizung Heizleitermaterial zu verwenden, dessen Temperaturkoeffizient möglichst groß ist, um das Absinken der Reglerbeheizung bei sinkender Stromstärke durch Widerstandszunahme des Reglerheizwiderstandes anzugleichen.The idea of the invention is heating conductor material for the regulator heating to use the temperature coefficient of which is as large as possible in order to prevent the Regulator heating with decreasing amperage by increasing the resistance of the regulator heating resistor to match.

Die Verwendung von Reglerbeheizungen aus Material mit hohem positivem Temperaturkoeffizienten wirkt sich auch bei Geräten vorteilhaft aus, derenHauptstromkreis seinen Widerstand nicht ändert. Die sogenanute Anheizung des Gerätes wird auch bei relativ niedrigem Kontaktdruck des Thermostaten nicht durch zu frühes Ansprechen desselben unterbrochen, dagegen tritt mit zunehmender Erwärmung eine günstig wirkende und zweckmäßige Verstärkung der Reglerbeheizung ein.The use of regulator heaters made from material with high positive Temperature coefficient also has a beneficial effect on devices whose main circuit its resistance does not change. The so-called heating of the device is also used Relatively low contact pressure of the thermostat is not due to an early response the same interrupted, on the other hand occurs with increasing warming a favorable effect and appropriate reinforcement of the controller heating.

Im allgemeinen dürfte als Heizleiter Beinnickel und Eisen als besonders zweckmäßig erscheinen.In general, nickel and iron should be used as heating conductors seem appropriate.
