Description

Die vorliegende Erfindung betrifft eine Kochflächeneinheit zum Einbau in eine Rahmenkonstruktion bzw. in einen Ausschnitt insbesondere eine Arbeitsfläche, bestehend aus einer Platte aus Glaskeramik oder einem ähnlichen Material als Kochfläche und einem an der Unterseite im Randbereich der Platte insbesondere mit Silikonkleber dauerelastisch verbundenen, metallischen, zur Auflage auf den Dichtrahmen bzw. in den Einbauausschnitt passenden Rahmenteil wobei der mit der Kochfläche verbundene Schenkel des insbesondere winkelförmigen Rahmenteils bündig vom Rand der Platte und parallel mit ihr nach innen verläuft und dort insbesondere rechtwinklig zum mit der Platte verbundenen Schenkel nach unten abbiegt.The present invention relates to a cooktop unit for installation in a frame construction or in a cutout, in particular a work surface, consisting of a plate made of glass ceramic or a similar material as the cooktop and a metallic, permanently elastic bonded to the underside in the edge region of the plate, in particular with silicone adhesive Support on the sealing frame or frame part fitting into the built-in cutout, the leg connected to the cooking surface of the angular frame part, in particular, running flush from the edge of the plate and parallel to the inside thereof, where it bends downward in particular at right angles to the leg connected to the plate.

Eine Kochflächeneinheit besteht im allgemeinen aus:

  • 1) einer Glaskeramik-Kochfläche oder aus ähnlichen Materialien,
  • 2) einem Halterahmen und
  • 3) einer dauerelastischen Verbindung zwischen der Kochfläche und dem Rahmen.
A cooktop unit generally consists of:
  • 1) a glass ceramic cooktop or similar materials,
  • 2) a holding frame and
  • 3) a permanently elastic connection between the cooking surface and the frame.

Auf dem Markt sind Konstruktionen mit anvulkanisierten Dichtungsprofilen bekannt.Constructions with vulcanized sealing profiles are known on the market.

Die Idee ist an sich gut, aber die Praxis hat gezeigt, daß sich in der Umsetzung erhebliche Toleranzprobleme ergeben, da nur über die Flanke abgedichtet wird und dadurch immer ein Preßsitz sichergestellt sein muß. Dies ist aber wegen der Toleranzen von Kochfläche und Rahmen sowie der Einbautoleranzen nicht möglich.The idea is good in itself, but practice has shown that there are considerable tolerance problems in the implementation, since sealing is only carried out over the flank and a press fit must therefore always be ensured. However, this is not possible due to the tolerances of the cooking surface and frame and the installation tolerances.

Eine unzureichende Abdichtung zwischen der Glaskeramik-Kochfläche und dem Rahmen kann sich im praktischen Gebrauch auf das Reinigungsverhalten und auf die Sicherheit bei der Bedienung auswirken. Übergelaufenes Kochgut kann so in die Fuge zwischen der Dichtung und dem Rahmen laufen und die elektrische Sicherheit nachteilig beeinflussen.In practical use, an insufficient seal between the glass ceramic cooktop and the frame can affect cleaning behavior and safety during operation. Spilled food can run into the joint between the seal and the frame and adversely affect electrical safety.

Aus der DE 30 09 961 A1 ist eine Glaskeramik-Kochfeldeinheit zum direkten Einbau in eine Arbeitsplatte aus Holz, Keramik oder Kunststoff bekannt, die aus dem Kochfeld mit der Kochplatte aus Glaskeramik und den Heizkörpern sowie aus einem umlaufenden, das Kochfeld abstützenden Montagerahmen besteht, der einerseits mit dem Randbereich der Kochplatte und andererseits mit dem Rand eines Arbeitsplattenausschnitts verbindbar ist, wobei zwischen dem Kochfeld und dem Montagerahmen Federelemente und Verstelleinrichtungen zum stufenlosen Annähern des Kochfelds mit der Kochplatte entgegen der Wirkung der Federelemente an den Montagerahmen angeordnet sind.From DE 30 09 961 A1 a glass ceramic cooktop unit for direct installation in a worktop made of wood, ceramic or plastic is known, which consists of the cooktop with the glass ceramic cooktop and the radiators as well as a surrounding mounting frame supporting the cooktop, which on the one hand with the edge area of the hotplate and on the other hand with the edge of a worktop cutout, spring elements and adjusting devices for steplessly approaching the hob with the hotplate are arranged against the action of the spring elements on the mounting frame between the hob and the mounting frame.

Aus der US-PS 5,036,831 ist eine rahmenlose Glaskeramik-Kochflächen-Einbaueinheit zu entnehmen, die aus

  • einer Kochfläche mit einem Einbauausschnitt und einem umlaufenden Rand im Einbauausschnitt, der einen nach unten gerichteten Flansch aufweist,
  • einer Glaskeramik-Platte mit einer umlaufenden Kante,
  • einem einheitlichen Stützring, mit einer ersten und zweiten im wesentlichen ebenen Oberfläche, wobei die zweite im wesentlichen ebene Oberfläche vertikal angeordnet ist,
  • und einem Dichtungsmaterial zwischen der ersten ebenen Oberfläche des Stützringes und der Unterseite der Glaskeramik-Platte, besteht,
wobei dieses Dichtungsmaterial die Glaskeramik-Platte mit dem Stützring verbindet und die zweite ebene Oberfläche des Stützringes gegen den nach unten gerichteten Flansch gehalten ist.From US-PS 5,036,831 a frameless glass ceramic cooktop built-in unit can be seen that
  • a cooking surface with a built-in cutout and a peripheral edge in the built-in cutout, which has a downward-pointing flange,
  • a glass ceramic plate with a peripheral edge,
  • a unitary support ring with a first and a second essentially flat surface, the second essentially flat surface being arranged vertically,
  • and a sealing material between the first flat surface of the support ring and the underside of the glass ceramic plate, consists,
wherein this sealing material connects the glass ceramic plate with the support ring and the second flat surface of the support ring is held against the downward flange.

Die in der DE 30 09 961 A1 und in der US-PS 5,036,831 vorgeschlagenen Vorgehensweisen haben sich in der Praxis als schwer realisierbar erwiesen, weil aufwendige Konstruktionen mit Montagerahmen und Verstelleinrichtungen bzw. Federelementen teuer herzustellen und problematisch einzubauen sind.The procedures proposed in DE 30 09 961 A1 and US Pat. No. 5,036,831 have proven to be difficult to implement in practice because complex structures with mounting frames and adjusting devices or spring elements are expensive to manufacture and problematic to install.

Aufgabe der Erfindung ist es, eine Kochflächeneinheit ohne die vorgenannten Nachteile zu schaffen und eine einfach, servicefreundliche Einbauweise zu ermöglichen, die eine dauerelastische und dichte Verbindung zwischen Glas/Glaskeramik und Halterahmen gewährleistet, auch wenn zwischen Kochfläche und Rahmen geometrische Toleranzen gegeben sind. Des weiteren ist es Aufgabe der Erfindung, die Sicherheit des Benutzers jederzeit sicherzustellen.The object of the invention is to provide a cooktop unit without the aforementioned disadvantages and to allow a simple, service-friendly installation method which ensures a permanently elastic and tight connection between glass / glass ceramic and holding frame, even if there are geometric tolerances between the cooktop and frame. Furthermore, it is an object of the invention to ensure the safety of the user at all times.

Die Aufgabe der Erfindung wird dadurch gelöst, daß der die kraftschlüssige Verbindung zwischen Platte und dem Rahmenteil bewirkende Kleber auf den Stirnseiten der Platte und des mit ihr verklebten Schenkels einen kraftschlüssig verbundenen umlaufenden Rand ausbildet, der bündig mit der Oberfläche der Platte abschließt und unter Ausbildung einer (Dicht-) Lippe die Unterseite des mit der Platte verbundenen Schenkels überragt.The object of the invention is achieved in that the adhesive effecting the positive connection between the plate and the frame part on the end faces of the plate and the leg glued to it forms a non-positively connected peripheral edge which is flush with the surface of the plate and forms one (Sealing) lip extends beyond the underside of the leg connected to the plate.

Die abdichtende Verbindung zwischen dem anvulkanisierten Kleberand und dem Dichtrahmen bzw. dem Einbauausschnitt erfolgt nun nicht über die vertikale Dichtflanke sondern wird in die horizontale Ebene gelegt. Die Lösung nach der Erfindung in Form einer anvulkanisierten Dichtlippe löst in überraschend einfacher Weise alle gestellten Anforderungen.The sealing connection between the vulcanized adhesive edge and the sealing frame or the installation cutout is now not made via the vertical sealing flank but is placed in the horizontal plane. The solution according to the invention in the form of a vulcanized sealing lip solves all the requirements in a surprisingly simple manner.

Die Kochflächeneinheit nach der Erfindung besteht daher aus

  • einer Glaskeramik-Kochfläche oder einem ähnlichen Material,
  • einem Halterahmen und
  • einem dauerelastisch anvulkanisierten Kleberand mit einer ausgebildeten Dichtlippe.
The cooking surface unit according to the invention therefore consists of
  • a glass ceramic cooktop or a similar material,
  • a holding frame and
  • a permanently elastic vulcanized adhesive edge with a trained sealing lip.

Die Dichtlippe stellt die Abdichtung zwischen der Kochflächeneinheit und dem Dichtrahmen bzw. dem Einbauauschnitt sicher, unabhängig von den Fertigungs- und Montagetoleranzen der Kochfläche einerseits und des Dichtrahmens bzw. des Einbauausschnittes andererseits.
Da die Abdichtung bei der vorgeschlagenen Ausführungsform nicht über die vertikale Flanke des Kleberandes erfolgt, sondern über eine ausgebildete Dichtlippe ist man in der Umsetzung frei von den hohen Anforderungen an die Toleranzen der Klebevorrichtung und des Dichtrahmens bzw. des Einbauausschnittes.The sealing lip ensures the seal between the cooking surface unit and the sealing frame or the installation cutout, regardless of the manufacturing and assembly tolerances of the cooking surface on the one hand and the sealing frame or the installation cutout on the other hand.
Since the sealing in the proposed embodiment does not take place via the vertical flank of the adhesive edge, but rather via a trained sealing lip, the implementation is free of the high demands on the tolerances of the adhesive device and the sealing frame or the mounting cutout.

Die Dichtung kann dabei einfach und schnell hergestellt werden.The seal can be produced quickly and easily.

Zwei Methoden der Herstellung sind dabei besonders bevorzugt:
Einmal die Herstellung in einer sog. Lehre, einer Form in der die Kochflächeneinheit fertig vorkonfektioniert wird.
Um die Einheit später leicht entfernen zu können, wird in die Lehre ein Trennmittel eingegeben oder die Lehre selbst wird aus einem geeigneten Material hergestellt, das von sich aus eine Trennwirkung aufweist wie z. B. PTFE.
Eine zweite Möglichkeit besteht darin, die Kochflächeneinheit direkt im Rahmen herzustellen.Two methods of production are particularly preferred:
First, the production in a so-called teaching, a form in which the cooktop unit is completely pre-assembled.
In order to be able to easily remove the unit later, a release agent is added to the teaching or the teaching itself is made from a suitable material that has a separating effect of its own, such as. B. PTFE.
A second option is to manufacture the hob unit directly in the frame.

In bevorzugter Ausführungsform beträgt die Dicke des durch den Kleber ausgebildeten Randes von 1,5 m bis 3,5 mm und weist die Dichtlippe Radien von ≥ 0,5 mm auf. So konnte problemlos eine jederzeit sichere Funktion der Rahmenkonstruktion erzielt werden.In a preferred embodiment, the thickness of the edge formed by the adhesive is from 1.5 m to 3.5 mm and the sealing lip has radii of 0,5 0.5 mm. This ensured that the frame construction could function reliably at all times.

Die vorgefertigte Kochflächeneinheit mit der Dichtlippe kann in jede gängige Rahmenkonstruktion eingebaut werden. Sehr gute Abdichtung durch die erfindungsgemäße Dichtlippe wurde sowohl bei Dichtrahmen mit seperatem Auflageschenkel wie bei Dichtrahmen aus Tiefzieh- oder Strangpreßprofilen aus Metall oder Kunststoff und auch bei einfachen Einbauausschnitten z. B. Blechwannen einer Herdmulde erzielt.The prefabricated cooktop unit with the sealing lip can be installed in any common frame construction. Very good sealing by the sealing lip according to the invention was used both in sealing frames with a separate support leg and in sealing frames made from deep-drawn or extruded profiles made of metal or plastic, and also with simple installation cutouts, for. B. sheet metal trays of a hob.

Die Verbindung der erfindungsgemäßen Kochflächeneinheit mit dem Dichtrahmen erfolgt dabei in einfacher Weise z. B. mittels einer Biegelasche, die an dem mit der Unterseite der Glaskeramikplatte verklebten Schenkeln oder auch an dem frei nach unten verlaufenden Schenkel vorgesehen sein kann und so umgebogen wird, daß sie eine kraftschlüssige Verbindung mit dem Dichtrahmen gewährleistet. Weitere Möglichkeiten der Verbindung mit dem Dichtrahmen bestehen über Keile hier insbesondere auch Kunststoffkeile oder über eine Schraubverbindung mit einem Schraubbolzen.The connection of the cooking surface unit according to the invention with the sealing frame takes place in a simple manner, for. B. by means of a bending tab, which can be provided on the legs glued to the underside of the glass ceramic plate or also on the leg which runs freely downwards and is bent over in such a way that it ensures a positive connection with the sealing frame. Other options for connection to the sealing frame are wedges, in particular plastic wedges, or a screw connection with a screw bolt.

Die Erfindung soll an den nachfolgenden Figuren 1 bis 9 und den dazugehörigen Ausführungsbeispielen näher verdeutlicht werden.The invention is to be illustrated in more detail in the following FIGS. 1 to 9 and the associated exemplary embodiments.

Figur 1 zeigt eine fertige Kochflächeneinheit (1) nach der Erfindung mit einer Glaskeramik-Kochfläche (2), mit dem winkelig ausgebildeten Rahmenteil (3), das mit der Unterseite der Glaskeramikplatte (2) mit einem Silikonkleber (5) verbunden ist. Der Silikonkleber (5) bildet dabei auf der Stirnseite der Platte (2) einen 2,5 mm dicken Silikonrand (4) der auch noch die Stirnseite des winkeligen Rahmens (3) als Dichtlippe (6) überragt. Figure 1 shows a finished cooking surface unit (1) according to the invention with a glass ceramic cooking surface (2), with the angular frame part (3) which is connected to the underside of the glass ceramic plate (2) with a silicone adhesive (5). The silicone adhesive (5) forms a 2.5 mm thick silicone edge (4) on the face of the plate (2) which also projects beyond the face of the angular frame (3) as a sealing lip (6).

Figur 2 zeigt das Prinzip der Herstellung der fertigen Kochflächeneinheit (1) mit der Dichtlippe (6) mittels einer Lehre (7), die aus PTFE gefertigt ist. Damit kann grundsätzlich auf ein sonst notwendiges Trennmittel (8) verzichtet werden. Die Lehre entspricht dabei dem Negativ eines modifizierten Original-Dichtrahmens. Figure 2 shows the principle of manufacturing the finished cooking surface unit (1) with the sealing lip (6) by means of a gauge (7) which is made of PTFE. In principle, an otherwise necessary release agent (8) can thus be dispensed with. The teaching corresponds to the negative of a modified original sealing frame.

Die Figur zeigt eine Glaskeramik-Kochfläche (2) mit einem mittels eines dauerelastischen Silikonklebers (5) verbundenen Rahmenteils (3), das auf die Lehre aufgelegt wird. Der Silikonkleber (5), der später den Silikonrand (4) ausbilden soll, wird nun zwischen die Lehre (7) und die Stirnflächen der Glaskeramikplatte (2) und des Halterahmens (3) eingebracht. Die Lehre (7) ist dabei so ausgebildet, daß sich der Silikonrand (4) nach unten zu einer Dichtlippe (6) ausformt, die die Unterseite des mit der Glaskeramikplatte (2) verbundenen Schenkels des Halterahmens (3) deutlich um 3 mm überragt.The figure shows a glass ceramic cooktop (2) with a frame part (3) connected by means of a permanently elastic silicone adhesive (5), which is placed on the teaching. The silicone adhesive (5), which will later form the silicone edge (4), is now inserted between the gauge (7) and the end faces of the glass ceramic plate (2) and the holding frame (3). The gauge (7) is designed so that the silicone edge (4) forms a sealing lip (6) downwards, which clearly projects 3 mm beyond the underside of the leg of the holding frame (3) connected to the glass ceramic plate (2).

Die, wie in Figur 1 gezeigt gefertigte Kochflächeneinheit wird dann aus der Lehre herausgenommen und in den Original-Dichtrahmen eingesetzt.The cooking surface unit manufactured as shown in FIG. 1 is then removed from the teaching and inserted into the original sealing frame.

In ähnlich einfacher Weise funktioniert die Herstellung mittels eines leicht modifizierten Original-Dichtrahmens, der zur Herstellung der Kochflächeneinheit allerdings mit einem Trennmittel versehen sein muß.The production works in a similarly simple manner by means of a slightly modified original sealing frame, which, however, must be provided with a release agent in order to produce the cooktop unit.

Die Figuren 6, 7, 8 und 9 zeigen Ausführungsbeispiele für Verbindungsmöglichkeiten mit vorgegebenen Dichtrahmen. Figures 6, 7, 8 and 9 show exemplary embodiments of connection options with predetermined sealing frames.

Figuren 6 a-d zeigen die Möglichkeit einer Verbindung der Kochflächeneinheit (1) mit dem Dichtrahmen (9) mittels einer umgebogenen Lasche (12), wobei sich die Lasche (12) nach Figur 6 einmal an dem mit der Glaskeramikplatte (2) verbundenen Schenkel des Rahmenteiles (3) befindet und nach Figuren 7 a/b an dem nicht mit der Platte (2) verbundenen freien Schenkel vorgesehen ist.Figures 6 ad show the possibility of connecting the cooking surface unit (1) to the sealing frame (9) by means of a bent-over tab (12), the tab (12) according to Figure 6 once on the leg of the frame part connected to the glass ceramic plate (2) (3) and is provided according to Figures 7 a / b on the free leg not connected to the plate (2).

In Figur 8 ist eine montierte Kochflächeneinheit (1) zu erkennen, die mittels eines Kunststoffkeiles (13) befestigt ist, während Figur 9 eine Verbindung der Kochflächeneinheit (1) in dem Dichtrahmen (9) bzw. dem Einbauausschnitt (11) mittels eines Schraubbolzens (14) zeigt.FIG. 8 shows an assembled cooking surface unit (1) which is fastened by means of a plastic wedge (13), while FIG. 9 shows a connection of the cooking surface unit (1) in the sealing frame (9) or the installation cutout (11) by means of a screw bolt ( 14) shows.

Die Erfindung zeigt eine einfache und preiswerte Möglichkeit der wirksamen Abdichtung zwischen einer Kochflächeneinheit und einem Dichtrahmen bzw. einem Einbauausschnitt wobei die Abdichtung durch eine Dichtlippe erfolgt, die an einem anvulkanisiertem Kleberand ausgebildet ist.The invention shows a simple and inexpensive possibility of effective sealing between a cooktop unit and a sealing frame or an installation cutout, the sealing being effected by a sealing lip which is formed on a vulcanized adhesive edge.
