Abstract

The method involves using a conducting track temp. sensor (6) associated with a cooking position (4). The resistance of the sensor is measured at a first operating temp. as a first reference resistance and at a different temp. as a second reference resistance. The temp. (T) of the sensor resistance (R) is derived from the two reference resistance values (R1,R2) and the associated temp. values (T1,T2) by T = T1+(R-R1)*(T2-T1)/(R2-R1).

Es stellen dar:They represent:

Fig. 1 eine Aufsicht auf eine Kochstelle eines Glaskeramikkochfeldes, wobei an der Unterseite der Glaskeramik vorgesehene Leiterbahnen sichtbar sind. Fig. 1 is a plan view of a hotplate of a glass ceramic hob, with conductor tracks provided on the underside of the glass ceramic being visible.

Fig. 2 eine Schnittansicht der Fig. 1, geschnitten längs der Linie 2-2. Fig. 2 is a sectional view of Fig. 1, taken along the line 2-2.

Fig. 3 eine perspektivische Ansicht eines Anschlußblocks. Fig. 3 is a perspective view of a terminal block.

Gemäß Fig. 1 weist ein Glaskeramikkochfeld 4 eine Kochstelle 6 auf, die gestrichelt umrandet ist und der eine nicht dargestellte Heizeinrichtung zugeordnet ist. Unmittelbar an der Unterseite der Glaskeramik sind Leiterbahnen angebracht, mit denen die Temperatur der Kochstelle bestimmt werden kann oder mit denen die Stellung eines auf der Kochstelle befindlichen Topfes durch kapazitive Messung bestimmt werden kann. Insgesamt sind sechs Leiterbahnen vorgesehen, von denen sich zwei Leiterbahnen 8 und 10, die der Temperatur­ bestimmung durch Widerstandsmessung dienen, diagonal durch die Kochstelle 6 erstrecken und vier Leiterbahnen 12, 14, 16 und 17, die Kochstelle konzentrisch fingerartig umgreifen und zur Kapazitätsmessung dienen.Referring to FIG. 1, a glass ceramic hob 4 a hotplate 6, which is outlined in phantom and is associated with a heater not shown. Directly on the underside of the glass ceramic there are conductor tracks with which the temperature of the hotplate can be determined or with which the position of a pot on the hotplate can be determined by capacitive measurement. A total of six conductor tracks are provided, of which two conductor tracks 8 and 10 , which are used to determine the temperature by measuring resistance, extend diagonally through the hotplate 6 and four conductive tracks 12 , 14 , 16 and 17 , grasp the hotplate concentrically and serve to measure the capacity.

Die Leiterbahnen sind jeweils bis in die Nähe des Randes des Glaskeramikkochfeldes 4 zu dessen Rahmen 18 hingeführt und liegen dort für eine Kontaktierung frei.The conductor tracks each lead up to the vicinity of the edge of the glass ceramic cooktop 4 to its frame 18 and are exposed there for contacting.

Die Leiterbahnen können durch Aufdampfen, durch elektrolytische Prozesse oder in anderer bekannter Weise an der Glaskeramik angebracht werden. Sie sind meist mit erheblich größerer Breite als Dicke ausgebildet, was in Fig. 1 nicht dargestellt ist. Auch können die zur Kontaktierung freiliegenden Enden in ihrer Fläche vergrößert sein.The conductor tracks can be attached to the glass ceramic by vapor deposition, by electrolytic processes or in another known manner. They are usually designed with a considerably greater width than thickness, which is not shown in FIG. 1. The areas exposed for contacting can also be enlarged in their area.

Fig. 2 zeigt eine der an der Unterseite der Glaskeramik 20 angebrachten Leiterbahnen, in dem Beispiel die Leiterbahn 10. An dem Rahmen 18 der Glaskeramik, der beispielsweise mittels eines Klebers 22 mit der Glaskeramik 20 verbunden ist, ist ein Anschlußblock 24 mittels Schrauben 26 verschraubt. Der Anschlußblock 24 besteht vorteilhafter Weise aus einem gießfähigen oder preßformbaren Kunststoff, in den metallische Verbindungsteile 28 eingegossen sind, welche gemäß Fig. 2 oben als federnde Kontaktzungen 30 vorstehen. Die anderen Enden der Verbindungsteile 28 sind als Lötfahnen 32 ausgebildet und mit Anschlußleitungen 34 verlötet. Die Dimensionierung des Anschlußblocks 24 und der Kontaktzungen 30 ist derart, daß die Kontaktzungen 30 bei an dem Rahmen 18 angeschraubtem Anschlußblock 24 in vorgespannter Anlage an den Leiterbahnen der Glaskeramik sind. Fig. 2 shows one of attached to the underside of the glass ceramic conductor paths 20, in the example, the interconnect 10. A connection block 24 is screwed to the frame 18 of the glass ceramic, which is connected to the glass ceramic 20 for example by means of an adhesive 22 , by means of screws 26 . The connecting block 24 advantageously consists of a castable or press-formable plastic, into which metallic connecting parts 28 are cast, which protrude as resilient contact tongues 30 according to FIG. 2 above. The other ends of the connecting parts 28 are designed as solder lugs 32 and soldered to connecting lines 34 . The dimensioning of the connection block 24 and the contact tongues 30 is such that the contact tongues 30 are in a prestressed contact with the conductor tracks of the glass ceramic when the connection block 24 is screwed onto the frame 18 .

Gemäß Fig. 3 entspricht die Anzahl der von dem Anschlußblock 24 vorstehenden Kontaktzungen 30 bzw. der von dem Anschlußblock 24 gehaltenen Verbindungsteile 28 der Anzahl der zu kontaktierenden Leiterbahnen. In Fig. 3 sichtbar sind Gewindelöcher 36 des Anschlußblocks 24 für dessen Verschraubung mit dem Rahmen 18. Referring to FIG. 3, the number of the protruding from the terminal block 24, contact tongues 30 and the connection parts 28 held by the terminal block 24 corresponds to the number of interconnects to be contacted. In Fig. 3 are visible threaded holes 36 of the terminal block 24 for the screw connection with the frame 18.

Es sind zahlreiche Ausführungsformen der Verbindungsteile 28 und des Anschlußblocks 24 möglich. Vorteilhafterweise sind die Kontaktzungen 30 vergoldet und bestehen aus Federbronze mit wohldefinierten elastischen Eigenschaften. Die Verbindungsteile 28 können insgesamt einteilig sein oder aus mehreren Teilen in elektrisch leitender Weise zusammengesetzt sein. Anstelle der Lötfahnen 32 können Quetschfahnen vorgesehen sein oder es können Buchsen ausgebildet sein, in die die Anschlußleitungen 34 eingeschoben werden und dann durch Verschrauben festgepreßt werden.Numerous embodiments of the connecting parts 28 and the connection block 24 are possible. The contact tongues 30 are advantageously gold-plated and consist of spring bronze with well-defined elastic properties. The connecting parts 28 can be in one piece as a whole or can be composed of several parts in an electrically conductive manner. Instead of the soldering lugs 32 , pinching lugs can be provided or bushings can be formed, into which the connecting lines 34 are inserted and then pressed tight by screwing.

Anstelle eines Kochfeldes oder einer Kochstelle aus Glaskeramik kann auch ein Kochfeld bzw. eine Kochstelle aus einem anderen Material vorgesehen sein, insbesondere aus einer Keramik vorzugsweise mit guter Wärmeleitung wie beispielsweise Siliciumnitrid oder Siliciumcarbid. Die Leiterbahnen am Kochfeld bzw. der Kochstelle können dann auch als Widerstandsheizelemente zum Beheizen des Kochfeldes bzw. der Kochstelle ausgebildet sein. Ferner können zusätzlich auch wieder Leiterbahnen zur Messung von Temperaturen, Kapazitäten oder Induktivitäten vorgesehen sein wie in den bereits beschriebenen Ausführungsformen.Instead of a hob or a hob Glass ceramic can also be a hob or a hob another material may be provided, in particular from a ceramic preferably with good heat conduction such as for example silicon nitride or silicon carbide. The Conductors on the hob or the hotplate can then also as resistance heating elements for heating the hob or the hotplate. Can also additionally also conductor tracks for measuring Temperatures, capacities or inductors are provided be as in the embodiments already described.

Die Anschlußvorrichtung gemäß der Erfindung ist somit zum Kontaktieren beliebiger Leiterbahnen am Kochfeld bzw. an der Kochstelle geeignet unabhängig von der Verwendung der Leiterbahnen oder dem Material des Kochfeldes bzw. der Kochstelle.The connection device according to the invention is thus for Contact any conductor tracks on the hob or on the Suitable for hotplates regardless of the use of the Conductor tracks or the material of the hob or the Hotplate.
