BeschreibungDescription
Die vorliegende Erfindung betrifft die Temperaturregelung von Elektroheizplatten, die als Tierwärmer im Liegebereich Anwendung finden.The present invention relates to the temperature control of electric heating plates, which are used as animal warmers in the lying area.
Bei Systemen, die bis dato in diesem Bereich eingesetzt werden, ist es Stand der Technik, daß in eine Elektroheizplatte sei es in der Ausführung mit Heizkabel, Heizleiter oder Folienheizung ein Fühler integriert wird, der dem angeschlossenen Temperaturregler, sei es P,I,D oder einer Kombination derselbigen den Temperaturistwert der Elektroheizplatte wiedergibt, und so entsprechend die Heizleistung ein bzw. ausgeschaltet wird.In systems that have been used in this area to date, it is state of the art that a sensor is integrated into an electric heating plate, whether in the version with heating cable, heating conductor or foil heating, which reports the actual temperature value of the electric heating plate to the connected temperature controller, be it P, I, D or a combination of the same, and the heating power is switched on or off accordingly.
Bei Elektrotierwärmern besteht nun der Nachteil, daß bei einem eingestelltem Sollwert unterhalb der Körperwärme der Tiere sich das Regelergebnis wesentlich verschlechtert, da das Tier die Platte erwärmt.The disadvantage of electric animal heaters is that if the set point is below the body temperature of the animal, the control result deteriorates significantly because the animal heats the plate.
Im ungünstigsten Falle, wenn die Temperatur zu niedrig ist, führt eine sehr gute Wärmeleitfähigkeit dazu, daß der Wärmestrom sich sehr leicht von den Ferkeln zuIn the worst case, when the temperature is too low, a very good thermal conductivity means that the heat flow is very easily transferred from the piglets to

Infolgedessen erwärmen die Ferkel im Extremfall den kälteren Bodem im Liegebereich, indem der Wärmefluß sich umgekehrt und nun vom Tier zur Platte geht, und zwar umso mehr, je besser die Wärmeleitfähigkeit desAs a result, in extreme cases the piglets heat up the colder floor in the lying area, as the heat flow is reversed and now goes from the animal to the plate, and the better the thermal conductivity of the

Schon ein einziges Ferkel auf der Platte, welches zufällig über demEven a single piglet on the plate, which happened to be above the
Fühler liegt, kann diesem ein Temperaturniveau signalisieren, das eine
Abschaltung auslöst. Bei schnell auskühlendem Material kann das dazu führen, daß die Platte kalt ist, wenn die übrigen Ferkel von der Sau zurück zum
Liegebereich kommen.

Der im Schutzanspruch angegebenen Erfindung liegt* da's Problem zugrunde, eine
Möglichkeit der Temperaturregelung von Elektroheizplatten, die als Tierwärmer dienen, zu schaffen, ohne daß der in der Platte integrierte Meßfühler durch ein
auf ihr liegendes Tier so beeinflußt wird, das dieser fälschlicherweise
der Regelung ein Signal vermittelt den Wärmefluß abzuschalten.The invention specified in the protection claim is based on the problem of creating a possibility for temperature control of electric heating plates that serve as animal warmers, without the sensor integrated in the plate being influenced by an animal lying on it in such a way that it falsely
The control system sends a signal to switch off the heat flow.
Das Problem wird mit den im Schutzanspruch aufgeführten Merkmalen gelöst.The problem is solved with the features listed in the protection claim.
Mit der Erfindung wird erreicht, daß an einer bestimmten Stelle derThe invention achieves that at a certain point of the
Elektroheizplatte im Regelfall immer eine Temperatur herrscht, die ca 10-12 °C über der übrigen Plattentemperatur liegt, doch inojedem Fall immer über derElectric heating plate usually has a temperature that is about 10-12 °C above the rest of the plate temperature, but in any case always above the
Körpertemperatur der auf im liegenden Tiere ( > 42°C ).Body temperature of the animals lying on the ground ( > 42°C ).
Diese Stelle hat mit ca. 20 Quadratzentimetern nur einen sehr geringen Flächenanteil auf der Platte.This spot has only a very small area of about 20 square centimeters on the plate.
Bei Systemen mit Heizfolie wird die Temperaturerhöhung an dieser Stelle erreicht, indem man entweder dort die Leiterbahnen konzentriert (Fig.l) oder aber die Leiterbahnbreite verringert. {Fig.2)In systems with heating foil, the temperature increase is achieved at this point by either concentrating the conductor tracks there (Fig.l) or by reducing the conductor track width. {Fig.2)
Wird ein Heizleiter in der Elektroplatte verwendet, wird die Temperaturerhöhung erreicht indem man eine höhere Konzentration an Windungen an dieser StelleIf a heating conductor is used in the electric plate, the temperature increase is achieved by using a higher concentration of windings at this point
auslegt.(Fig.3)(Fig.3)
Somit kann in Zukunft vermieden werden, daß durch die Tiere die Regelung der Elektroheizplatten nicht mehr verfälscht werden kann.This will prevent the animals from distorting the control of the electric heating plates in the future.
