Die Erfindung bezieht sich auf eine Elektrische Heizplatte mit einer gedruckten Schaltung, die mittels eines beliebigen Verfahrens auf eine Platte mit dielektrischen Eigenschaften aufgebracht ist. Bei den dielektrischen Platten handelt es sich normalerweise um Metallbleche mit einem dielektrischen Überzug aus glasierter Keramik, auf die anschliessend die gedruckte Schaltung aufgebracht wird, die den elektrischen Widerstand bildet.The invention relates to an electric heating plate with a printed circuit, which by means of any method is applied to a plate with dielectric properties. The dielectric panels are usually Metal sheets with a dielectric coating made of glazed ceramic, onto which the printed circuit is then applied which forms the electrical resistance.
Die bisher bekannten Heizplatten v/eisen den Nachteil auf, dass während des Betriebes thermische Ungleichmässigkeiten auf der Oberfläche der Platte auftreten, die darauf zurückzuführen sind, dass die gedruckte Schaltung gleichförmig ist, das heisst der Querschnitt ist konstant. Wenn eine derartige Heizplatte während des Betriebes senkrecht aufgestellt bzw. an der Wand befestigt sind, weist der obere Teil eine höhere Temperatur auf als der untere Teil. Dieses ist auf die KonvektiorEströme zurückzuführen, die den oberen Teil der Heizplatte während ihres Anstiegs mit einer höheren Temperatur erreichen.The previously known heating plates have the disadvantage that thermal irregularities occur during operation occur on the surface of the board due to the fact that the printed circuit is uniform, i.e. the cross-section is constant. If such a heating plate is set up vertically or attached to the wall during operation, the upper part has a higher temperature than the lower part. This is due to the convection currents that the Reach the upper part of the heating plate at a higher temperature as it rises.
Diese thermischen Sprünge der Heizfläche verursachen Spannungen und führen zu unkontrollierbaren Deformierungen, die die gedruckte Schaltung zerstören können.These thermal jumps in the heating surface cause stresses and lead to uncontrollable deformations that can destroy the printed circuit.
Äusserdeta ist die thermische Leistung der bekannten Heizplatten mangelhaft.Äusserdeta is the thermal output of the known heating plates inadequate.
Es ist Aufgabe der Erfindung, die vorgenannten Nachteile auszuschalten, was dadurch erreicht wird, dass die erfindungsgemässe elektrische Heizplatte einen unterschiedlichen Widerstandsxvert der gedruckten Schaltung auf der Heizfläche aufweist, wq-It is the object of the invention to eliminate the aforementioned disadvantages, which is achieved in that the inventive electrical heating plate has a different resistance value of the printed circuit on the heating surface, wq-

Längsrichtung erhalten wird, und zwar gemäss den Konstanten der Verlustleistung der Platte gemäss die Arbeitsstellung der- *~ selben, wodurch eine gleichmässige Temperatur der Platte an LO allen Punkten der Oberfläche erreicht wird. οLongitudinal direction is obtained, namely according to the constants of the power loss of the plate according to the working position of the * ~ same, whereby a uniform temperature of the plate LO is reached at all points on the surface. ο
Γ? Die Unregelmässigkeit des Widerstandswertes der gedruckten co Schaltung wird erfindungsgemäss dadurch erreicht, dass die Pro-ο portion der gedruckten Schaltung je Oberflächeneinheit" geändert ., wird. Hierdurch erhält man eine Art "kompensierte gedruckte Schaltung", denn je grosser der Querschnitt des elektrischen Leitelementes je Längseinheit, je kleiner der Widerstand undΓ? The irregularity of the resistance value of the printed co circuit is achieved according to the invention in that the Pro-ο portion of the printed circuit per surface unit "changed ., will. This gives a kind of "compensated printed circuit" because the larger the cross-section of the electrical Guide element per longitudinal unit, the smaller the resistance and
damit eine niedrigere Temperatur.thus a lower temperature.
Durch eine versuchsmässig ohne Schwierigkeit bestimmbare Oberflächenänderung der gedruckten Schaltung auf der Platte, wird die Gleichmässigkeit der ausgestrahlten Temperatur erreicht.By means of a test that can be determined without difficulty Surface change of the printed circuit on the plate, the uniformity of the radiated temperature is achieved.
Eine elektrische Heizplatte, deren gedruckte Schaltung dem Erfindungsgedanken entspricht, ist in den beiliegenden Zeichnungen dargestellt.An electric heating plate, the printed circuit of which corresponds to the inventive idea, is shown in the accompanying drawings shown.
Die Figur .1\zeigt eine schematische Ansicht dieser gedruckten Schaltung, die Figur 2 eine andere Ausführungsform und die Figur 3 einen Schmitt gemäss der Linie A-B der Figur 2..Figure .1 \ shows a schematic view of this printed circuit, Figure 2 shows another embodiment and Figure 3 shows a Schmitt along the line A-B of Figure 2 ..
In den Zeichnungen ist die die gedruckte Schaltung tragende Platte mit (1) bezeichnet,die über die Anschlüsse (2) an das Stromnetz" angeschlossen wird.In the drawings, the board carrying the printed circuit is denoted by (1), which is connected to the Power grid "is connected.
Wie ersichtlich weist de gedruckte Schaltung Zonen (3) grösserer Breite als die Zonen (4-) auf, so dass in den erstenAs can be seen, the printed circuit zones (3) have a greater width than the zones (4-), so that in the first
(3) ein geringerer Widerstandswert herrscht als in den zweiten(3) there is a lower resistance value than in the second
(4) und damit auch eine geringere Wärmeabgabe.(4) and thus also a lower heat emission.
Aus der 'Figur 3 ist ersichtlich, dass die Zonen (3) nicht nur eine grössere Flächenausdehnung als die Zonen (A-) aufweisen, sondern auch eine grössere Dicke haben können·From 'Figure 3 it can be seen that the zones (3) do not only have a larger area than the zones (A-), but can also have a greater thickness
