Stabausdehnungsregler zum Übertemperaturschutz bei der Beheizung von Glaskeramik-KochplattenRod expansion controller for overtemperature protection when heating glass ceramic hotplates
In der Heizgerätetechnik werden in zunehmendem Maße Glaskeramik-Kochplatten verwendet. Diese Kochplatten werden häufig mittels eines spiralförmig verlaufenden Mantelrohrheizstabes, der unterhalb der Glaskeramik-Kochplatte am oberen Hand eines muldenförmigen Reflektortopfes angebracht sind, beheizt.Glass ceramic hotplates are increasingly being used in heating appliance technology used. These hotplates are often used by means of a spiral-shaped tubular heating rod, which is attached below the glass ceramic hotplate on the upper hand of a trough-shaped reflector pot are heated.
Diese Glaskeramik-Kochplatten bedürfen einer Temperaturbegrenzung, da der Wert von 700° C an der Unterseite der Glaskeramik-Kochplatte weder im Leerlauf noch bei teilweiser Abdeckung durch einen Kochtopf überschritten werden darf.These glass ceramic hotplates require a temperature limit, because the value of 700 ° C on the underside of the glass ceramic hotplate is neither idle nor partially Cover may be exceeded by a saucepan.

Es ist bekannt, diese Temperaturbegrenzung mittels eines Stabausdehnungsreglers vorzunehmen. Im bekannten Fall liegt der Stabausdehnungsregler zwischen der Glaskeramik-Kochplatte und dem Heizelement. Durch diese Anordnung ist in nachteiliger Weise eine sehr hohe Bauhöhe der Mulden gegeben.It is known to limit this temperature by means of a To make the rod expansion controller. In the known case, the rod expansion regulator is located between the glass ceramic hotplate and the heating element. This arrangement has the disadvantage of a very high overall height of the troughs.
Der Neuerung liegt die Aufgabe zugrunde, den Stabausdehnungsregler so anzuordnen, daß die Bauhöhe wesentlich niedriger ist.The innovation is based on the task of the rod expansion controller to be arranged so that the overall height is significantly lower.
Die Lösung dieser Aufgabe gelingt gemäß der Neuerung dadurch, daß der Stabausdehnungsregler unterhalb des Mantelrohrheizstabes und innerhalb des Reflektortopfes angeordnet ist.The solution to this problem is achieved according to the innovation in that the rod expansion regulator is below the tubular heating rod and is arranged within the reflector pot.
Anhand der Zeichnung wird die Neuerung näher beschrieben.The innovation is described in more detail using the drawing.
Unterhalb einer Glaskeramik-Kochplatte 4- liegt ein spiralförmig verlaufender Mantelrohrheizstab 2, der oberhalb eines Reflektortopfes 3 in bekannter Weise angeordnet ist. Unterhalb dieses Mantelrohrheizstabes und innerhalb des Reflektortopfes 3 liegt ein Stabausdehnungsregler 1, der in üblicher Weise auf den elektrischen Versorgungskreis der Heizung für die Kochplatte einwirkt. Abhängig von der durch die Glaskeramik-Kochplatte entzogenen Wärmemenge ändert sich die Raumtemperatur in dem Reflektortopf 3 sowie die Intensität der Strahlung des Mantelrohrheizstabes 2 auf den Stabausdehnungsregler 1. Die Justierung des Stabausdehnungsreglers 1 wird so vorgenommen, daß eine Temperatur von 600° C an der Unterseite der Glaskeramik-Kochplatte bei ungünstigen Betrieb (Topf steht nur teilweise über der Beheizung) nicht überschritten wird.Below a glass ceramic hotplate 4- there is a spiral running jacket tube heating rod 2, which is above a Reflector pot 3 is arranged in a known manner. Below this tubular heating rod and inside the reflector pot 3 is a rod expansion regulator 1, which in the usual way on the electrical supply circuit of the heater for the hotplate acts. Depending on the amount of heat extracted by the glass ceramic hotplate, the Room temperature in the reflector pot 3 and the intensity of the radiation from the tubular heating rod 2 on the rod expansion controller 1. The adjustment of the rod expansion controller 1 is made so that a temperature of 600 ° C at the The underside of the glass ceramic hotplate is not exceeded during unfavorable operation (pot is only partially above the heating) will.

Wie zu erkennen ist, nutzt der Stabausdehnungsregler 1 den Raum des Reflektortopfee 3 aus, ohne die Ausdehnung in der Vertikalen zu vergrößern. Die Bauhöhe der kompletten Glaskeramik-Kochplatte ist dadurch sehr niedrig.As can be seen, the rod expansion controller 1 uses the Space of the reflector pot 3 without increasing the extent in the vertical. The overall height of the entire glass ceramic hotplate is therefore very low.
