Description

Die Erfindung bezieht sich auf ein Kochfeld gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a hob according to the preamble of claim 1.

Ein derartiges Kochfeld ist bekannt aus der EP-A-0 359 028, wobei der Lichtleiter die Form eines Glasstabes aufweist, der den Isolationseinsatz des Heizelementes ringförmig am Außenumfang mit Abstand umgibt. Daher ist der Glasstab in einem am lsolationseinsatz befestigten Rinnenprofil gehaltert.Such a hob is known from EP-A-0 359 028, the light guide being in the form of a glass rod which surrounds the insulation insert of the heating element in a ring on the outer circumference at a distance. The glass rod is therefore held in a channel profile attached to the insulation insert.

Bei einem weiteren bekannten Kochfeld (DE-OS 40 02 322) ist ein ringförmiger Lichtleiter seitlich außerhalb des als Strahlungsheizkörper ausgebildeten, ein napfförmiges Gehäuse aufweisenden Heizelementes angeordnet und z.B. mittels einer taschenförmigen Halterung mit dem Heizelement-Gehäuse verbunden.In another known cooktop (DE-OS 40 02 322), an annular light guide is arranged laterally outside the heating element designed as a radiant heater and having a cup-shaped housing, and e.g. connected to the heating element housing by means of a pocket-shaped holder.

Der Erfindung liegt die Aufgabe zugrunde, den Aufbau des Heizelementes und des Lichtleiters konstruktiv und montagemäßig zu vereinfachen.The invention has for its object to simplify the construction of the heating element and the light guide in terms of construction and assembly.

Diese Aufgabe wird gemäß der Erfindung gelöst durch die im Kennzeichnungsteil des Patentanspruches 1 aufgeführten Maßnahmen. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Patentansprüchen.This object is achieved according to the invention by the measures listed in the characterizing part of claim 1. Advantageous further developments of the invention result from the following patent claims.

Durch die Integration des Lichtleiters im Heizelement ergibt sich eine vergleichsweise niedrige thermische Beanspruchung des Glasmaterials bei Betrieb des Heizelementes und man erhält ohne zusätzliche Halteelemente oder dgl. eine sehr einfache Anordnung und Montage des Lichtleiters. Die konstruktive und montagemäßige Vereinfachung ergibt sich insbesondere dadurch, daß der als Lichtleiter dienende Glasring die Seitenwand eines napfförmigen, den lsolationseinsatz aufnehmenden, Glaskörpers einstückig bildet.The integration of the light guide in the heating element results in a comparatively low thermal stress on the glass material during operation of the heating element, and a very simple arrangement and assembly of the light guide is obtained without additional holding elements or the like. The structural and assembly-related simplification results in particular from the fact that the glass ring serving as a light guide forms the side wall of a cup-shaped glass body which receives the insulation insert and forms one piece.

Die Erfindung ist anhand von in der Zeichnung dargestellten Ausführungsbeispielen nachstehend erläutert.The invention is explained below with reference to exemplary embodiments shown in the drawing.

Beim Ausführungsbeispiel gemäß Fig. 1 ist mit 1 ein das Kochfeld abdeckender Träger aus glaskeramischem, teiltransparenten Material bezeichnet, unterhalb welchem in der Regel mehrere Heizelemente 2 mit Abstand voneinander angeordnet sind. Das Heizelement besteht aus einem napfförmigen, nach oben offenen Gehäuse 3 aus Blechmaterial, in dem auf dem Napfboden ein im wesentlichen ebener, elektrische Heizwendeln 4 tragender Isolationseinsatz 5 sowie randseitig ein damit einstückiger oder aber separater, ringförmiger Isolationseinsatz 6 angeordnet ist. Dieses Heizelement 2 wird in nicht weiter dargestellter Weise gegen die Unterseite des glaskeramischen Trägers 1 gedrückt, wobei die innere Fläche des ringförmigen Isolationseinsatzes 6 eine durch die elektrischen Heizwendeln 4 beheizbare Koch- oder Stellfläche für Töpfe oder dgl. bestimmt. Der äußere Durchmesser des als Wandelement des Isolationseinsatzes 5/6 dienenden Isolationseinsatzes 6 ist geringfügig, z.B. um wenige Millimeter geringer als der Innendurchmesser des Gehäuses 3, so daß zwischen Isolationseinsatz 6 und Gehäuse 3 ein Ringspalt 7 vorhanden ist, in welchem ein als Glasring ausgebildeter Lichtleiter 8 angeordnet, z.B. eingefügt oder eingedrückt oder eingebettet ist. Der vorzugsweise als geschlossener Glasring ausgebildete Lichtleiter 8 besitzt eine im wensentlichen mit der Gehäusehöhe übereinstimmende vertikale Ausdehnung und ist mit wenigstens einer Öffnung 9 versehen, in die eine Lichtquelle 10 einer nicht weiter dargestellten Leuchteinrichtung hineinragt. Die Lichtquelle kann als Glüh- oder Glimmlampe ausgebildet sein und steht über ein Anschlußelement 11 und elektrische Leitungen mit einer nicht dargestellten Steuereinrichtung in Verbindung, z.B. mit einer Einrichtung zur Restwärmeanzeige, wobei die Leuchteinrichtung einen temperaturabhängigen Schalter aufweist, der ab einer Sicherheitstemperatur von z.B. 50°C die Lichtquelle 10 einschaltet und damit signalisiert, daß ein Berühren der Stellfläche des Trägers 1 zu unterlassen ist. Die von der Lichtquelle 10 ausgehenden Lichtstrahlen werden im Lichtleiter 8 geleitet, wodurch der gesamte Lichtleiter in Richtung zum glaskeramischen Träger 1 eine Leuchtwirkung ausübt, durch die gleichzeitig eine optische Kennzeichnung der vorgenannten Stellfläche erfolgt. Anstelle einer sogenannten Restwärmeanzeige kann hierzu vorgesehen sein, daß die Leuchteinrichtung gleichzeitig mit dem Einschalten des Heizelementes eingeschaltet wird.In the exemplary embodiment according to FIG. 1, 1 denotes a support made of glass-ceramic, partially transparent material, covering the hob, below which, as a rule, a plurality of heating elements 2 are arranged at a distance from one another. The heating element consists of a cup-shaped, upwardly open housing 3 made of sheet metal material, in which an essentially flat insulation insert 5 carrying electrical heating coils 4 is arranged on the bottom of the bowl, as well as an integral or separate annular insulation insert 6 on the edge thereof. This heating element 2 is pressed in a manner not shown, against the underside of the glass-ceramic carrier 1, the inner surface of the annular insulation insert 6 determining a cooking or setting surface for pots or the like which can be heated by the electric heating coils 4. The outer diameter of the insulation insert 6 serving as a wall element of the insulation insert 5/6 is slight, for example a few millimeters smaller than the inside diameter of the housing 3, so that an annular gap 7 is present between the insulation insert 6 and the housing 3, in which a light guide designed as a glass ring is present 8 arranged, for example inserted or pressed or embedded. The light guide 8, which is preferably in the form of a closed glass ring, has a vertical extension that essentially corresponds to the height of the housing and is provided with at least one opening 9, into which a light source 10 of a lighting device (not shown) projects. The light source can be designed as an incandescent or glow lamp and is connected via a connection element 11 and electrical lines to a control device (not shown), for example to a device for displaying residual heat, the lighting device has a temperature-dependent switch which switches on the light source 10 from a safety temperature of, for example, 50 ° C. and thus signals that the support 1 should not be touched. The light rays emanating from the light source 10 are guided in the light guide 8, as a result of which the entire light guide in the direction of the glass-ceramic carrier 1 exerts a lighting effect, by means of which the above-mentioned footprint is simultaneously optically identified. Instead of a so-called residual heat indicator, it can be provided that the lighting device is switched on at the same time as the heating element is switched on.

Beim Ausführungsbeispiel gemäß Fig. 2 ist das Gehäuse 12 des Heizelementes 2' als einstückiger Glaskörper ausgebildet und besitzt eine napfartige Form, die geeignet ist, zur Aufnahme des oder der Isolationseinsätze 5, 6. Hierbei stellt die zylindrische Seitenwand 13 einen Lichtleiter dar, der lichttechnisch über die Öffnung 9 wiederum verbunden ist mit der vor beschriebenen Leuchteinrichtung. Das Ausführungsbeispiel gemäß Fig. 3 unterscheidet sich von Fig. 2 nur durch die Anordnung der Lichtquelle 10. Bei Fig. 3 ist an der Unterseite der Bodenfläche der Glaskörper 12 im nach oben offenen Behälter 13 vorgesehen, der mit seiner offenen Seite an der Bodenfläche anliegt und eine Lampenfassung 18 für die Lichtquelle 10 besitzt. Der Behälter kann im Inneren ganz oder teilweise mit einer Licht reflektierenden Oberfläche versehen sein. Durch diese zentrale, vorzugswseise hinsichtlich des Glaskörpers 12 mittige Anordnung der Lichtquelle 10 erhält man eine sehr intensive und gleichmäßige Ausleuchtung des Lichtleiters und eine gute optische Wirkung.2, the housing 12 of the heating element 2 'is designed as a one-piece glass body and has a cup-like shape, which is suitable for receiving the insulating insert or inserts 5, 6. Here, the cylindrical side wall 13 represents a light guide, the lighting technology is in turn connected via the opening 9 to the lighting device described above. The exemplary embodiment according to FIG. 3 differs from FIG. 2 only in the arrangement of the light source 10. In FIG. 3, the glass body 12 is provided in the upwardly open container 13 on the underside of the bottom surface, the open side of which rests on the bottom surface and has a lamp holder 18 for the light source 10. The inside or part of the container can be provided with a light-reflecting surface. This central arrangement of the light source 10, preferably central with respect to the glass body 12, results in a very intensive and uniform illumination of the light guide and a good optical effect.

Bei beiden Ausführungsbeispielen kann vorgesehen sein, daß der den Lichtleiter bildende Glasring in Form des separaten Ringteils bei Fig. 1 oder der Seitenwand 13 bei Fig. 2 an den seitlichen Ringflächen 14, 15 und/oder an der unteren Ringfläche 16 (Fig. 1) einen Reflexionsbelag aufweist, z.B. an dieser Stelle verspiegelt ist, so daß das den Lichtleiter durchflutende Licht nach oben hin sehr stark reflektiert wird und andererseits die seitliche Wärmedämmung des Heizelementes verstärkt wird.In both exemplary embodiments it can be provided that the glass ring forming the light guide in the form of the separate ring part in FIG. 1 or the side wall 13 in FIG. 2 on the lateral ring surfaces 14, 15 and / or on the lower ring surface 16 (FIG. 1) has a reflective coating, e.g. is mirrored at this point, so that the light flowing through the light guide is very strongly reflected upwards and on the other hand the lateral thermal insulation of the heating element is reinforced.
