Abstract

A hotplate is fitted by means of a relatively wide and shallow mounting ring, whose outer edge rests on a mounting plate made from glass, ceramic or other materials. At its edge, the mounting ring is adhered to mounting plate using a thermally stable adhesive, which simultaneously forms a seal against cooked articles running through. The sheet metal insert ring covers the inner circumference of mounting a opening in the mounting plate and has an upper outwardly directed flange engaging over the seal. Simultaneously the seal, in conjunction with the insert ring, centers the hotplate in the mounting opening. A release ring can be inserted for releasing the hotplate.

Description

Die Erfindung betrifft eine elektrische Kochplatte mit einem sie umgebenden Einbauring, die in eine Einbauöffnung einer Einbauplatte eingebaut ist und bei der in der Verbindung zwischen Kochplatte und Einbauplatte eine Klebung vorgesehen ist.The invention relates to an electric hotplate with a mounting ring surrounding it, which is installed in an installation opening of a mounting plate and in which an adhesive is provided in the connection between the hotplate and mounting plate.

Aus der DE-A-2 819 118 ist eine Glaskeramikkocheinheit bekanntgeworden, bei der die mehrere Kochstellen überdeckende Glaskeramikkochfläche in einen profilierten Einbaurahmen eingeklebt ist, der die Öffnung einer Einbauplatte übergreift. Die Klebung ist hier relativ unproblematisch, weil Glaskeramikflächen an ihrem Außenumfang wegen der geringen Wärmequerleitung keine wesentlich erhöhten Temperaturen annehmen.From DE-A-2 819 118 a glass ceramic cooking unit has become known, in which the glass ceramic cooking surface covering several cooking areas is glued into a profiled mounting frame which engages over the opening of a mounting plate. Adhesion is relatively unproblematic here because glass ceramic surfaces do not assume significantly higher temperatures on their outer circumference due to the low heat transfer.

Aus der DE-A-2 205 545 ist ein Kochplatteneinbau bekanntgeworden, bei dem ein die Wandung einer Einbauöffnung abdeckender Einsatzring vorgesehen ist. Die Kochplatte ist bei dieser Ausführung durch übliche Spannbügel befestigt.From DE-A-2 205 545 a hotplate installation has become known, in which an insert ring is provided which covers the wall of an installation opening. In this version, the hotplate is fastened using conventional tensioning brackets.

Aufgabe der Erfindung ist es, den Einbau einer Kochplatte auch in empfindliche Einbauplatten, beispielsweise Keramik- oder Glasplatten vornehmen zu können.The object of the invention is to enable the installation of a hotplate in sensitive mounting plates, for example ceramic or glass plates.

Diese Aufgabe wird dadurch gelöst, daß der Einbauring auf den Kochplattenkörper einer Guß-Einzelkochplatte aufgepreßt ist und daß die Klebung zwischen dem Einbauring und der Einbauplatte erfolgt.This object is achieved in that the mounting ring is pressed onto the hotplate body of a cast single hotplate and that the gluing takes place between the mounting ring and the mounting plate.

Während bisher die Kochplatten stets mit der Einbauplatte verspannt wurden, wird die Kochplatte durch die Klebung vorteilhaft so eingebaut, daß sie hier eine Versteifung der Kochplatte in dem besonders gefährdeten Bereich der Einbauöffnung bildet, anstatt den Rand der Einbauöffnung mit einer zusätzlichen Kraft zu belasten. Je nach der Art des verwendeten Klebers kann dieser gleich die Dichtfunktion übernehmen oder die Klebung kann zwischen einer zwischengelegten Dichtung und dem Einbauring sowie der Einbauplatte erfolgen. Für den Fall, daß die Kochplatte leicht wieder lösbar sein soll, könnte beispielsweise eine Aufreißeinrichtung nach Art eines eingelegten Reißdrahtes vorgesehen sein, der von innen ergriffen werden kann. Bei der Zuverlässigkeit der Kochplatten ist allerdings ein Aus- und Einbau einzelner Platten recht selten. Das Aufschneiden könnte auch mit einem Winkelmesser von innen oder außen erfolgen.While previously the hot plates were always braced with the mounting plate, the hot plate is advantageously installed by the adhesive so that it forms a stiffening of the hot plate in the particularly vulnerable area of the installation opening instead of stressing the edge of the installation opening with an additional force. Depending on the type of adhesive used, this can take on the sealing function immediately or the adhesive can be applied between an interposed seal and the mounting ring and the mounting plate. In the event that the hotplate is to be easily removable again, for example a tear-open device in the manner of an inserted tear wire could be provided, which can be gripped from the inside. With the reliability of the hot plates, however, removing and installing individual plates is very rare. The cutting could also be done with a protractor from the inside or outside.

Bevorzugt ist ferner die Anordnung eines Einsatzringes, der den Innenumfang der Einbauöffnung abdeckt, so daß diese gegen Strahlung der Kochplatte ebenso wie gegen mechanische Beschädigung geschützt ist und zusätzlich versteift wird. Auch dieser Einsatzring kann eingeklebt werden. Vorzugsweise greift er mit einem äußeren Flansch über die Oberfläche der Einbauplatte, wo dann der Kleber bzw. das Dichtmaterial zwischengelegt ist. Besonders vorteilhaft ist eine Ausführung, wo der gleiche Kleber- oder Dichtring den Einsatzring gegenüber der Arbeitsplatte abdichtet und dem Einbauring von innen gegen Eindringen von Flüssigkeit dicht hält. Im unteren Bereich kann der Einsatzring etwas nach innen versetzt sein, so daß der Dicht- oder Kleberring um die obere Kante der Einbauöffnung herumgreifen und so besonders gut abdichten und eine flexible stoßgeschützte Kante bildet.Also preferred is the arrangement of an insert ring which covers the inner circumference of the installation opening, so that it is protected against radiation from the hotplate as well as against mechanical damage and is additionally stiffened. This insert ring can also be glued in. It preferably engages with an outer flange over the surface of the mounting plate, where the adhesive or the sealing material is then interposed. A particularly advantageous embodiment is one in which the same adhesive or sealing ring seals the insert ring from the worktop and keeps the mounting ring tight from the inside against the ingress of liquid. In the lower area, the insert ring can be offset somewhat inwards so that the sealing or adhesive ring grips around the upper edge of the installation opening and thus seals particularly well and forms a flexible, impact-protected edge.

Als Kleber können flüssige bis pastöse Kleber und auch in fester Form aufzubringende Kleber verwendet werden, die relativ hoch wärmebeständig sein sollten. Allerdings sind die Temperaturen bei einer gegenüber temperaturgeschützten Kochplatte mit einem vorzugsweise sehr breiten, flachen Einbauringes an dessen Au- ßenumfang nicht mehr so hoch. Es gibt Kleber, die diese Temperaturen ohne weiteres ertragen, beispielsweise Keramikkleber auf der Basis von Aluminium-, Silicium- oder Magnesiumoxid, Graphit oder Circonbasis, die Temperaturen von 1000 bis 3000° C ertragen. Es gibt auch Einkomponenten-Cyanacrylat-Klebstoffe, die unter dem Einfluß der Luftfeuchtigkeit schnell aushärten und sehr große Haftkräfte und eine gute Wärmebeständigkeit haben.Liquid to pasty adhesives and also adhesives to be applied in solid form, which should be relatively highly heat-resistant, can be used as adhesives. However, the temperatures are no longer so high in the case of a hotplate which is protected against temperature and has a preferably very wide, flat mounting ring on its outer circumference. There are adhesives that can easily withstand these temperatures, for example ceramic adhesives based on aluminum, silicon or magnesium oxide, graphite or zirconium, which can withstand temperatures of 1000 to 3000 ° C. There are also one-component cyanoacrylate adhesives that cure quickly under the influence of atmospheric humidity and have very high adhesive forces and good heat resistance.

Ferner ist es möglich, daß der Einsatzring aus einer Doppelhülse besteht, die eine mit Abstand zur am Außenumfang der Einbauöffnung anliegende Innenwandung hat, die über einige Verbindungsstege oder dgl. mit dieser verbunden ist. Sie bildet einen zusätzlichen Wärmeschutz und könnte gleichzeitig zur Zentrierung beitragen.Furthermore, it is possible for the insert ring to consist of a double sleeve which has a spacing from the inner wall which bears against the outer circumference of the installation opening and which is connected to the latter via some connecting webs or the like. It forms additional heat protection and could also contribute to centering.

Die Zeichnungen zeigen einige Ausführungsbeispiele der Erfindung:

  • Fig. 1 eine teilgeschnittene Seitenansicht einer Elektrokochplatte und eines Teils einer Einbauplatte,
  • Fig. 2 das Detail 11 in Fig. 1,
  • Fig.3 eine abgewandelte Ausführung dieses Details und
  • Fig. 4 bis 6 weitere Ausführungsformen.
The drawings show some embodiments of the invention:
  • 1 is a partially sectioned side view of an electric hotplate and part of a built-in plate,
  • 2 shows the detail 11 in FIG. 1,
  • 3 shows a modified version of this detail and
  • 4 to 6 further embodiments.

Fig. 1 zeigt eine elektrische Kochplatte 11 mit einem üblichen Kochplattenkörper aus Gußmaterial, an dessen Unterseite elektrische Heizwiderstände in spiralige Nuten eingebettet sind. Der Kochplattenkörper, dessen obere Fläche eine ebene, nur in der Mitte etwas ausgenommene, geschlossene Kochfläche bildet, ist von einem Einbauring 12 umgeben, der am Außenumfang des Kochplattenkörpers 13 durch Aufpressen festgelegt ist. Er hat einen flach umgekehrt U-förmigen Querschnitt mit leicht abfallender Außenflanke und liegt auf einer aus Glas, Keramik oder eventuell auch anderen mehr oder weniger empfindlichen Materialien bestehenden Einbauplatte 14 auf, die eine Einbauöffnung 15 hat, die wesentlich größer ist als der Außenumfang des Kochplattenkörpers 13 und nur wenig kleiner als der Außenumfang des abwärts gerichteten äußeren Randes 16 des Einbauringes 12.Fig. 1 shows an electric hotplate 11 with a conventional hotplate body made of cast material, on the underside of which electrical heating resistors are embedded in spiral grooves. The hotplate body, the upper surface of which forms a flat closed cooking surface which is only slightly recessed in the middle, is surrounded by an installation ring 12 which is fixed on the outer circumference of the hotplate body 13 by being pressed on. It has a flat, inverted U-shaped cross section with a slightly sloping outer flank and lies on a mounting plate 14 made of glass, ceramic or possibly also other more or less sensitive materials, which has an installation opening 15 which is substantially larger than the outer circumference of the hotplate body 13 and only slightly smaller than the outer circumference of the downward outer edge 16 of the mounting ring 12.

Der Umfang bzw. die Wandung 17 der Einbauöffnung 15 wird von einem Einsatzring 18 aus Blech abgedeckt, der in diese Öffnung eingesetzt ist und dort selbsthaftet oder eingeklebt sein kann. Er hat einen oberen Flansch 19 (Fig. 2), der bis nahe an den Außenrand 16 des Einbauringes 12 heranreicht. Zwischen dem Flansch 19 und dem Rand 16 liegt ein Ring 20, der beispielsweise aus einem pastösen und wärmebeständigen Kleber bestehen kann oder aus einem wärmebeständigen Dichtring, der mit dem Einsatzring 18, dem Einbauring 12 und der Arbeitsplatte 14 durch Klebung verbunden ist, und zwar entweder durch Selbstklebung oder durch einen besonders aufgebrachten Klebstoff. Der Ring 20 wird durch den Einsatzring 18 geführt und zentriert damit gleichzeitig den Einbauring 12 und dichtet an Einsatzring und Einbauring gleichzeitig ab.The circumference or wall 17 of the installation opening 15 is made from an insert ring 18 Covered sheet metal, which is inserted into this opening and can be self-adhesive or glued there. It has an upper flange 19 (FIG. 2) which extends close to the outer edge 16 of the mounting ring 12. Between the flange 19 and the edge 16 is a ring 20, which may consist, for example, of a pasty and heat-resistant adhesive or of a heat-resistant sealing ring which is connected to the insert ring 18, the mounting ring 12 and the worktop 14 by adhesive, either by self-adhesive or by a specially applied adhesive. The ring 20 is guided through the insert ring 18 and thus simultaneously centers the mounting ring 12 and seals the insert ring and mounting ring at the same time.

Fig. 3 zeigt eine Variante, bei der bei im übrigen gleicher Ausführung der obere Teil 21 des Einsatzringes 18a etwas nach innen zurückversetzt ist, so daß sich der Ring 20a um die obere Kante 22 der Arbeitsplatte herum erstrecken kann und dadurch gute Dichtung und mechanischen Schutz bietet.Fig. 3 shows a variant in which, in the rest of the same design, the upper part 21 of the insert ring 18a is set back somewhat inwards, so that the ring 20a can extend around the upper edge 22 of the worktop and thereby good sealing and mechanical protection offers.

Fig. 4 zeigt eine Ausführung ohne metallischen Einsatzring, bei der ein angeklebter Dichtring 20b um die obere Ecke 22 der Arbeitsplatte herumgreift. In ihn ist ein Reißdraht 23 eingelegt, der von innen ergriffen und aufgerissen werden kann, so daß die Kochplatte bei einer eventuellen Demontage leicht gelöst werden kann.Fig. 4 shows an embodiment without a metallic insert ring, in which an adhesive sealing ring 20b engages around the upper corner 22 of the worktop. In it, a tear wire 23 is inserted, which can be gripped and torn open from the inside, so that the hotplate can be easily detached if disassembled.

Fig. 5 zeigt ebenfalls eine Ausführung mit Reißdraht entsprechend Fig. 4, bei der jedoch der Dichtring 20c über die ganze Innenfläche der Einbauöffnung reicht und diese abdeckt. Diese Ausführung eignet sich insbesondere bei einem Dichtringmaterial, das hoch wärmefest und auch gut isolierend ist. Man könnte hier eine innere Beschichtung aus einem reflektierenden Material vorsehen, um die Arbeitsplatte weiter vor Temperatureinflüssen zu schützen.FIG. 5 also shows an embodiment with a tear wire corresponding to FIG. 4, in which, however, the sealing ring 20c extends over the entire inner surface of the installation opening and covers it. This version is particularly suitable for a sealing ring material that is highly heat-resistant and also good insulating. An inner coating made of a reflective material could be provided here in order to further protect the worktop from the effects of temperature.

Fig. 6 zeigt eine Ausführung, bei der ein Dichtring 20d unter den halb-torusförmig gewölbten Flansch 19d des Einsatzringes 18d gelegt ist. In diesem Falle ist der Einbauring mittels einer Klebung 20' direkt auf der Arbeitsplatte und mit der Außenfläche des Flansches 19d verbunden.6 shows an embodiment in which a sealing ring 20d is placed under the semi-toroidally curved flange 19d of the insert ring 18d. In this case, the mounting ring is connected by an adhesive 20 'directly on the worktop and to the outer surface of the flange 19d.

Es wird ein sicherer, dichter und besonders flacher Kochplatteneinbau geschaffen, der auch die Verwendung von mechanisch und thermisch empfindlichen Einbauplatten ermöglicht.A safe, dense and particularly flat hotplate installation is created, which also enables the use of mechanically and thermally sensitive mounting plates.
