Description

Die Erfindung bezieht sich auf ein Glaskeramik-Kochfeld, die eine Glaskeramikplatte mit einer ebenen Oberseite und mit einer eine Noppenstruktur aufweisenden Unterseite sowie Strahlungsheizkörper oder Induktionsbeheizung umfasst, die unterhalb der Glaskeramikplatte angeordnet sind und Teilflächen um die Beheizung herum freilassen.The invention relates to a glass-ceramic cooktop, which comprises a glass ceramic plate with a flat upper side and with a knobbed structure having underside and radiant heater or induction heating, which are arranged below the glass ceramic plate and release partial surfaces around the heating.

Aus DE 102 11 520 A1 ist eine Glaskeramik-Kochfläche bekannt, an deren Vorderseite eine Bedien- und/oder Anzeigefront vorgesehen ist, die mit einer Stufe beginnt und in Richtung einer Bedienungsperson abfällt, um eine pultförmige Bedien- und/oder Anzeigefront zu bilden. Durch die Stufe wird ein Ablaufschutz gebildet und auf dem Kochfeld platziertes Kochgeschirr daran gehindert, über die Bedien- und/oder Anzeigefront zu gleiten. Die Ausbildung einer breiten Facette auf der Oberseite einer Glaskeramikplatte zur Bildung eines Ablaufschutzes beim Einsatz als Kochfläche ist außerdem aus DE 103 44 439 B3 und DE 102 40 147 A1 bekannt.Out DE 102 11 520 A1 a glass ceramic cooking surface is known, at the front of an operating and / or display front is provided, which starts with a step and drops in the direction of an operator to form a desk-shaped operating and / or display front. Through the step a drain protection is formed and placed on the hob cookware prevented from sliding over the control and / or display front. The formation of a wide facet on top of a glass ceramic plate to form a drain protection when used as a cooking surface is also out DE 103 44 439 B3 and DE 102 40 147 A1 known.

In DE 10 2010 032 119 ist angegeben, dass wenn die Oberseite einer als Kochfeld verwendeten Glaskeramikplatte über die Formgebung mit Walzen hergestellt wird, die Unterseite meist mit Noppen versehen ist. Zur Verbesserung des Anzeigebereichs wird eine glatte Unterseite dadurch geschaffen, dass die durch die Noppen geschaffenen Unebenheiten durch organischen Polymer beseitigt werden.In DE 10 2010 032 119 is stated that when the top of a glass ceramic plate used as a cooking surface is produced via the shaping with rollers, the underside is usually provided with knobs. To improve the display area, a smooth underside is created by eliminating the bumps created by the nubs by organic polymer.

Eine Glaskeramikplatte mit unterseitiger Noppenstruktur ist aus WO 03/086019 A1 bekannt. Die Glaskeramikplatte weist ein randnahes Tastenfeld auf, an der die Unterseite der Glaskeramikplatte als glatte Zone gestaltet ist. Diese glatte Zone wurde dadurch erhalten, dass eine Walze, mit der man die Noppenstruktur herstellt, eine glatte Ringzone aufweist.A glass ceramic plate with underside nub structure is made WO 03/086019 A1 known. The glass ceramic plate has a keypad close to the edge, on which the underside of the glass ceramic plate is designed as a smooth zone. This smooth zone was obtained by virtue of the fact that a roll with which the nub structure is produced has a smooth annular zone.

Aus der DE 196 33 706 C2 sind Glaskeramikplatten für Kochfelder bekannt, die auf ihrer Unterseite mit einer Noppenstruktur versehen sind, außer einem noppenlosen Streifen. Im Bereich dieses noppenlosen Streifens verlaufen die Oberseite und die Unterseite der Glaskeramikplatte genau parallel, so dass dort kapazitive Sensoren angebracht werden können.From the DE 196 33 706 C2 are known glass ceramic plates for hobs, which are provided on its underside with a knobbed structure, except a knobless strip. In the area of this noppenlosen strip, the top and bottom of the glass ceramic plate run exactly parallel, so that there capacitive sensors can be attached.

Die Noppenstruktur auf der Unterseite der Glaskeramikplatte macht diese weniger empfindlich gegenüber Kratzer während der Herstellung und in der Montage. Die Höhen der Noppen bewegen sich zwischen 40 und 200 µm und sind von der glatten Oberseite her durch die Glaskeramikplatte hindurch gut sichtbar. Dies gilt auch dann, wenn sich unterhalb der Glaskeramikplatte ein Displaybereich befindet. Deshalb möchte man dort die Noppen gern entfernt haben. Die Glaskeramikplatten für Kochfelder sind jedoch sehr empfindlich, so dass Wegschleifen der Noppen bedenklich erscheint. Da die Höhen der Noppen schwanken, ist es nämlich kaum möglich, nur die Noppen wegzuschleifen, man muss schon etwas in die Oberfläche der Unterseite des Kochfeldes hineinschleifen. Dadurch entsteht aber eine Stufe in dem Kochfeld, was die Gefahr des Bruches entlang dieser Stufe nach sich zieht, Belastungsfall: Last von oben während Nutzung. Der Erfindung liegt die Aufgabe zugrunde, ein Glaskeramik-Kochfeld mit einer Glaskeramikplatte zu schaffen, das in wenigsten einem Displaybereich noppenfrei ist.The nub structure on the underside of the glass ceramic plate makes it less sensitive to scratches during manufacture and assembly. The heights of the nubs are between 40 and 200 μm and are clearly visible from the smooth upper side through the glass-ceramic plate. This also applies if there is a display area below the glass ceramic plate. Therefore you would like to have the pimples removed there. However, the glass ceramic plates for hobs are very sensitive, so that wegschleifen the knobs appears questionable. Since the heights of the nubs fluctuate, it is hardly possible to grind away only the knobs, you have to grind something into the surface of the bottom of the hob. But this creates a Level in the hob, which causes the risk of breakage along this level, load case: load from above during use. The invention has for its object to provide a glass ceramic hob with a glass ceramic plate, which is knob-free in at least one display area.

Die gestellte Aufgabe wird dadurch gelöst, dass der noppenfreie Displaybereich in den Randbereich der Glaskeramikplatte verlegt wird und als geschliffene und polierte Flachfacette ausgeprägt wird, die stufenlos in die mit Noppen versehene Unterseite des Kochfeldes übergeht.This object is achieved in that the knob-free display area is laid in the edge region of the glass ceramic plate and is pronounced as ground and polished Flachfacette that merges steplessly in the provided with knobs underside of the hob.

Als Facette hat der geschliffene und polierte Displaybereich einen, wenn auch geringen, Neigungswinkel gegenüber der Plattenebene, so dass es einen stufenlosen Übergang zwischen der glatten Displaybereichseite und der Noppenfläche gibt. Der Winkel kann als ein flacher Winkel bezeichnet werden, man kann aber auch einen stumpfen Winkel am Körper der Glaskeramikplatte feststellen, nämlich zwischen Noppenfeld und Facette. Es hat sich gezeigt, dass die empfindliche Glaskeramikplatte ohne Gefährdung der Beschädigung oder des Zerbrechens so für die Verwendung bei einem verbesserten Glaskeramik-Kochfeld eingesetzt werden kann.As a facet, the ground and polished display area has a, albeit small, angle of inclination relative to the disk plane, so there is a smooth transition between the smooth display area side and the nub surface. The angle can be referred to as a shallow angle, but you can also determine an obtuse angle on the body of the glass ceramic plate, namely between knobbed area and facet. It has been found that the sensitive glass ceramic plate can be used without endangering the damage or the breakage for use in an improved glass ceramic hob.

Der Neigungswinkel der Flachfacette gegenüber der Plattenebene der Glaskeramikplatte liegt vorzugsweise im Bereich von 2° bis 6°. Die Breite der Flachfacette kann je nach Kochfeld zwischen 10 bis 60 mm betragen. Zur Verhüllung von Strukturen unterhalb des Kochfeldes kann außerhalb des Displaybereichs die Glaskeramikplatte mit einer Unterseitenbeschichtung versehen werden.The angle of inclination of the flat facet relative to the plane of the plate of the glass-ceramic plate is preferably in the range of 2 ° to 6 °. The width of the flat facet can be between 10 and 60 mm depending on the hob. To conceal structures below the hob can Outside of the display area, the glass ceramic plate are provided with a bottom coating.

Ein Ausführungsbeispiel wird anhand der Zeichnung beschrieben. Dabei zeigt Fig. 1 eine Glaskeramikplatte von der Unterseite in leicht perspektivischer Ansicht, und Fig. 2 die Oberseite der Glaskeramikplatte.An embodiment will be described with reference to the drawing. It shows Fig. 1 a glass ceramic plate from the bottom in a slightly perspective view, and Fig. 2 the top of the glass ceramic plate.

Die dargestellte Glaskeramikplatte weist eine Oberseite 1 und eine mit Noppen 20 versehene Unterseite 2 auf. Die Oberseite 1 ist glatt und zur Auflage von Kochgeschirr geeignet. Die genoppte Unterseite 2 schützt die Glaskeramikplatte bei der Verarbeitung gegen Kratzer. Die Höhe der Noppen liegt im Bereich von 40 bis 200 µm. Ein Randstreifen der Glaskeramikplatte ist als noppenfreie Flachfacette 3 mit glatter, ebener, schräg geneigter Oberfläche gestaltet. Die Flachfacette 3 wird durch Schleifen und Polieren des Randbereichs der Glaskeramikplatte hergestellt, die ursprünglich bis zum Rande mit Noppen versehen sein konnte. Der Facettenanschliff erfolgt in einem Winkelbereich zwischen 2° bis 6° gegenüber der Plattenebene. Bei einem Kochfeld im Haushaltsbereich betrug der Facettenanschliffwinkel 3° und die Facettenbreite 35 mm. Größere Platten können einen breiteren Facettenstreifen aufweisen.The illustrated glass ceramic plate has an upper side 1 and a lower side 2 provided with nubs 20. The top 1 is smooth and suitable for supporting cookware. The dimpled underside 2 protects the glass ceramic plate against scratches during processing. The height of the nubs is in the range of 40 to 200 microns. An edge strip of the glass ceramic plate is designed as a knob-free flat facet 3 with a smooth, flat, obliquely inclined surface. The flat facet 3 is produced by grinding and polishing of the edge region of the glass ceramic plate, which could originally be provided to the edge with nubs. The facet grinding takes place in an angle range between 2 ° to 6 ° with respect to the plate plane. For a domestic hob, the facet grinding angle was 3 ° and the facet width was 35 mm. Larger plates may have a wider facet strip.

Die Unterseite 2 der Glaskeramikplatte ist mit einer Unterseitenbeschichtung 4 versehen, außer an Sichtfenster 5, die sich an Stellen des Flachfacetten-Randbereichs 3 und auch im Noppenbereich befinden können. Die Unterseitenbeschichtung 4 deckt Strukturen unterhalb des Kochfeldes ab.The underside 2 of the glass ceramic plate is provided with a bottom coating 4, except for viewing window 5, which may be located in places of the flat facet edge region 3 and also in the nub region. The underside coating 4 covers structures below the hob.

In dem Sichtfenstern 5 können Symbole oder Schrift erscheinen, wie sie zum Beispiel von LED-Displayeinheiten 6 von unten auf das zugeordnete Sichtfenster 5 projeziert werden.In the viewing window 5 symbols or font may appear as they are projected, for example by LED display units 6 from below to the associated viewing window 5.

Es versteht sich, dass zu dem Glaskeramik-Kochfeld noch Heizkörper gehören, die unterhalb der Glaskeramikplatte angeordnet sind, jedoch nicht dargestellt werden brauchen.It is understood that belong to the glass ceramic hob still radiator, which are arranged below the glass ceramic plate, but need not be shown.
