Description
Die Erfindung umfasst eine Küchenarbeitsplatte mit induktiv beheiztem Kochfeld, ein Verfahren zu ihrer Herstellung und Verwendung.The invention comprises a kitchen worktop with inductively heated hob, a process for their preparation and use.
Induktionskochfelder finden aufgrund ihrer guten Heizleistung und vielen Sicherheitsvorteilen eine immer größere Verbreitung. Bei einem Induktionskochfeld wird mit Hilfe eines magnetischen Wechselfeldes Wärme in ferromagnetischen Materialien erzeugt. Es ermöglicht ein schnelles Aufheizen der Töpfe und Pfannen und sorgt gleichzeitig dafür, dass der restliche Teil des Kochfeldes nicht erwärmt wird. Wird der Heizvorgang abgeschlossen, so hat das Kochfeld nur die Restwärme die von den Kochgeräten als Rückerwärmung abgegeben wird. Im Vergleich zu herkömmlichen Kochplatten wird beim Induktionsherd ein größerer Teil der Energie dazu verwendet, Wärme im Topf und nicht auf der Kochplatte zu erzeugen. Zudem bietet das Induktionskochfeld auch unter Sicherheitsaspekten Vorteile. Eine eingeschaltete Kochplatte heizt nur, wenn sich ein geeignetes Kochgeschirr aus einem ferromagnetischen Metall darauf befindet.Induction hobs are becoming increasingly popular due to their good heating performance and many safety benefits. In an induction hob, heat is generated in ferromagnetic materials using an alternating magnetic field. It allows the pots and pans to heat up quickly while ensuring that the remaining part of the hob is not heated. If the heating process is completed, the hob has only the residual heat that is returned by the cooking appliances as reheating. Compared to conventional hotplates, the induction cooker uses a larger amount of energy to create heat in the pot and not on the hotplate. In addition, the induction hob also offers advantages in terms of safety. An on-board hotplate will only heat if there is a suitable cookware made of ferromagnetic metal on it.
Wie alle Kochfelder wird auch das Induktionskochfeld in der Regel in eine Aussparung der Küchenarbeitsplatte eingesetzt. Dieser Vorgang verringert jedoch die Planarität der Arbeitsplatte und schafft neue Fugen, welche eine hygienische Reinigung der Arbeitsplatte erschweren. Zudem sind die Fugen nur schwer Abzudichten, so dass Wasser unter die Arbeitsplatte gelangen kann. Dieser Wassereintritt kann das Material der Arbeitsplatte oder der angeschlossenen Geräte beschädigen. Auch stellt Feuchtigkeit in Spalten oder Fugen einen idealen Nährboden für Schimmel dar, was bei Verarbeitung und Zubereitung von Lebensmitteln ein nicht zu unterschätzendes Problem darstellt. Neben diesen technischen und hygienischen Gesichtspunkten sind auch unter ästhetischen Gründen völlig planare Arbeitsplatten in Küchen sehr gefragt.Like all hobs, the induction hob is usually inserted into a recess in the kitchen worktop. However, this process reduces the planarity of the worktop and creates new joints, which complicate a hygienic cleaning of the worktop. In addition, the joints are difficult to seal, so that water can get under the worktop. This ingress of water can damage the material of the worktop or attached equipment. Also, moisture in cracks or gaps is an ideal breeding ground for mold, which is a problem that should not be underestimated when processing and preparing food. In addition to these technical and hygienic aspects, completely planar worktops in kitchens are also in great demand for aesthetic reasons.
Die Aufgabe der Erfindung liegt darin, eine Arbeitsplatte mit integriertem Induktionskochfeld und kratzfester Beschichtung bereitzustellen, die keine Aussparungen, Fugen, Vertiefungen, Anhebungen, Ränder und/oder andere Unebenheiten am Kochfeld aufweist. Die Arbeitsplatte soll auf der gesamten Oberfläche planar sein und ein möglichst einheitliches Erscheinungsbild aufweisen.The object of the invention is to provide a worktop with integrated induction cooktop and scratch-resistant coating which has no recesses, joints, depressions, elevations, edges and / or other irregularities on the cooktop. The worktop should be planar on the entire surface and have a uniform appearance as possible.
Die Aufgabe der vorliegenden Erfindung wird erfindungsgemäß durch eine Küchenarbeitsplatte mit Induktionskochfeld nach den unabhängigen Ansprüchen 1, 10, und 12 gelöst. Bevorzugte Ausführungen gehen aus den Unteransprüchen hervor.The object of the present invention is achieved by a kitchen worktop with induction hob according to the
Die Küchenarbeitsplatte mit Induktionskochfeld umfasst mindestens eine Glasscheibe mit einer Länge von größer 100 cm und einer Breite von größer 40 cm. Die Dicke der Glasscheibe kann vom Fachmann im Rahmen der Anwendung gewählt werden, bevorzugt sind Dicken zwischen 3 mm und 30 mm, besonders bevorzugt 5 mm bis 10 mm.The kitchen worktop with induction hob comprises at least one glass pane with a length of more than 100 cm and a width of more than 40 cm. The thickness of the glass pane can be selected by a person skilled in the art within the scope of the application; thicknesses of between 3 mm and 30 mm, more preferably 5 mm to 10 mm, are preferred.
Auf der Glasscheibe sind Kochfeldmarkierungen aufgebracht. Die durch die Kochfeldmarkierungen begrenzte innere Fläche (Ai) ist kleiner als 70 %, bevorzugt kleiner 50 % der Gesamtfläche (AG) der Glasscheibe. Die innere Fläche (Ai) ergibt sich aus der durch äußere Umrandung der Kochfeldmarkierung resultierenden Fläche. Sie entspricht der minimalen Fläche in der alle einzelnen Kochfelder enthalten sind. Dabei sind in Abhängigkeit von der Anzahl der einzelnen Kochfelder und ihrer Anordnung zueinander auch mehreckige oder abgerundete innere Flächen (Ai) möglich. Der nicht von der inneren Fläche (Ai) belegte Teil der Glasscheibenoberfläche kann als Arbeits- oder Abstellfläche auf der erfindungsgemäßen Küchenarbeitsplatte genutzt werden.Hob markings are applied to the glass pane. The inner surface (A i ) delimited by the cooktop markings is less than 70%, preferably less than 50% of the total area (A G ) of the glass pane. The inner surface (A i ) results from the area resulting from the outer border of the cooktop marking. It corresponds to the minimum area in which all individual hobs are included. In this case, depending on the number of individual cooktops and their arrangement to each other and polygonal or rounded inner surfaces (A i ) possible. The part of the glass pane surface not occupied by the inner surface (A i ) can be used as a work or storage surface on the kitchen worktop according to the invention.
Unter den Kochfeldmarkierungen ist auf der Rückseite der Glasscheibe ein Induktionskochfeld angebracht. Das Induktionskochfeld ist dabei so ausgerichtet, dass geeignete, auf den Kochfeldmarkierungen abgestellte, Töpfe erwärmt werden. Die Töpfe müssen dabei ein ferromagnetisches Material enthalten. Die dem Topf benachbarten Bereiche der Glasscheibe werden nur durch den Topf selbst geringfügig erwärmt, nicht jedoch durch das Induktionsfeld.Under the cooktop markings on the back of the glass pane an induction cooktop is attached. The induction hob is aligned so that suitable, parked on the cooktop markers, pots are heated. The pots must contain a ferromagnetic material. The areas of the glass pane adjacent to the pot are only slightly heated by the pot itself, but not by the induction field.
Die Glasscheibe weist bevorzugt eine Länge von größer 150 cm, bevorzugt größer 200 cm auf. Die Größenbereiche der Glasscheibenlänge sind bevorzugt 150 cm bis 400 cm, besonders bevorzugt 200 cm bis 300 cm.The glass pane preferably has a length of greater than 150 cm, preferably greater than 200 cm. The size ranges of the glass pane length are preferably 150 cm to 400 cm, particularly preferably 200 cm to 300 cm.
Die innere Fläche (Ai) ist bevorzugt kleiner als 50 %, besonders bevorzugt kleiner als 30 %, insbesondere bevorzugt kleiner 20 % der Gesamtfläche (AG) der Glasscheibe. Damit können gleichzeitig mehr als 70 % der Glasscheibe als Arbeits- und Abstellfläche genutzt werden.The inner surface (A i ) is preferably less than 50%, more preferably less than 30%, most preferably less than 20% of the total area (A G ) of the glass sheet. At the same time, more than 70% of the glass pane can be used as work and storage space.
Die Glasscheibe weist auf der Unterseite eine keramische Farbe und/oder einen Druck auf. Diese bewirkt, dass die unter der Glasscheibe liegenden Teile wie beispielsweise das Induktionskochfeld nicht sichtbar sind. Grundsätzlich sind verschiedene keramische Farben möglich, diese müssen jedoch so weit temperaturbeständig sein, dass sie der vom Topf bei eingeschaltetem Induktionsfeld abgegebenen Wärme widerstehen. Beispiele für keramische Farben sind Dispersionsfarben, enthaltend anorganische Pigmente wie TiO2, Fe2O3, und Cr2O3 und/oder Gemische davon.The glass pane has a ceramic color and / or a pressure on the underside. This causes the underlying glass parts such as the induction hob are not visible. In principle, various ceramic colors are possible, but they must be so far temperature resistant that they resist the heat emitted by the pot when the induction field is turned on. Examples of ceramic paints are emulsion paints containing inorganic pigments such as TiO 2 , Fe 2 O 3 , and Cr 2 O 3 and / or mixtures thereof.
Die keramische Farbe umfasst bevorzugt eine keramische Siebdruckfarbe.The ceramic paint preferably comprises a ceramic screen printing ink.
Die Glasscheibe umfasst Einscheibensicherheitsglas. Neben Einscheibensicherheitsglas sind auch Mehrscheiben- oder Verbundsicherheitsgläser möglich. Die eingelegten Zwischenschichten müssen jedoch den im Bereich der Kochfeldmarkierung entstehenden Temperaturschwankungen widerstehen.The glass pane includes tempered safety glass. In addition to single-pane safety glass, multi-pane or laminated safety glass is also possible. The inserted intermediate layers must, however, withstand the temperature fluctuations arising in the area of the hob mark.
Mit reflektierenden oder farbigen Zwischenschichten lassen sich optische und funktionelle Effekte integrieren. Beispiele für funktionelle Beschichtungen sind IR reflektierende Zwischenschichten, besonders bevorzugt silberhaltige Zwischenschichten.With reflective or colored interlayers optical and functional effects can be integrated. Examples of functional coatings are IR-reflecting intermediate layers, particularly preferably silver-containing intermediate layers.
Die Glasscheibe enthält bevorzugt Aussparungen, besonders bevorzugt Aussparungen für Armaturen, Spüle, Spülfeld und/oder Spülbecken. Damit ist es möglich in die erfindungsgemäße Küchenarbeitsplatte entsprechende Nassarmaturen zu integrieren. Ein entsprechendes Spülbecken wird bevorzugt unterhalb der erfindungsgemäßen Küchenarbeitsplatte montiert, so dass der planare Charakter der Arbeitsfläche nicht beeinträchtig wird.The glass pane preferably contains recesses, particularly preferably recesses for fittings, sink, Spülfeld and / or sink.

Die Glasscheibe weist auf der Oberfläche eine kratzfeste Beschichtung auf, enthaltend bevorzugt Metalloxide wie Al2O3, SiO2, ZrO2, SnO2, Y2O3, Si3N4 und/oder Gemische davon. Die Schichtdicke liegt bevorzugt bei 100 nm bis 25000 nm, besonders bevorzugt bei 1000 nm bis 5000 nm. Diese kratzfeste Beschichtung verhindert Beschädigungen auf der Oberfläche der erfindungsgemäßen Küchenarbeitsplatte. Insbesondere das Abstellen von Küchengeräte oder das Schneiden von Lebensmitteln auf der Arbeitsplatte können die Arbeitsfläche leicht verkratzen und das optische Erscheinungsbild stören. Die Heizleistung der Kochflächen wird dadurch nicht beeinträchtigt.The glass pane has a scratch-resistant coating on the surface, preferably containing metal oxides such as Al 2 O 3 , SiO 2 , ZrO 2 , SnO 2 , Y 2 O 3 , Si 3 N 4 and / or Mixtures thereof. The layer thickness is preferably 100 nm to 25,000 nm, particularly preferably 1000 nm to 5000 nm. This scratch-resistant coating prevents damage to the surface of the kitchen worktop according to the invention. In particular, the placement of kitchen appliances or cutting food on the countertop can easily scratch the work surface and disturb the visual appearance. The heating power of the cooking surfaces is not affected.
Die Glasscheibe weist bevorzugt auf der Rückseite, d.h. auf und/oder seitlich der Seite mit dem angebrachten Induktionskochfeld, eine Beleuchtung, besonders bevorzugt LEDs oder OLEDs auf. Diese können als Leuchtquelle die Arbeitsfläche von unten und/oder von der Seite beleuchten.The glass sheet preferably has on the back, i. on and / or side of the side with the attached induction hob, a lighting, particularly preferably LEDs or OLEDs on. These can illuminate the work surface from below and / or from the side as a light source.
Die Glasscheibe weist bevorzugt eine schmutzabweisende, besonders bevorzugt hydrophobe Beschichtung auf. Diese erhöht den Kontaktwinkel von polaren Flüssigkeiten wie Wasser auf der Oberfläche der Scheiben und verringert damit die Benetzung der Oberfläche. Die Flüssigkeit läuft schneller ab und reinigt die Oberfläche. Zusätzlich wird damit die Bildung von Kalkablagerungen erschwert. Entsprechende Beschichtungen können hydrophobe Silane wie Alkylalkohol- bzw. Alkylchlorsilanen, beispielsweise Octyltrimethoxysilan enthalten. Zusätzlich können TiO2-Partikel auf der Oberfläche aufgebracht werden. Diese zersetzen unter Lichteinwirkung katalytisch organische Schmutzpartikel an der Scheibenoberfläche. Beispiele für derartige Beschichtungen werden auch in den Patentanmeldungen

In a first step, a glass sheet is provided. This is preferably cleaned and abraded the edges of the disc.
In einem zweiten Schritt werden die Kochfeldmarkierungen auf der vorbereiteten Scheibe angebracht. Dies kann durch Einritzen oder durch Aufdrucken hitzebeständiger Keramikfarben erfolgen. Eine weitere Möglichkeit ist die Gravur mithilfe eines geeigneten Lasers.In a second step, the hob marks are placed on the prepared disc. This can be done by scratching or by printing heat-resistant ceramic colors. Another option is engraving with the help of a suitable laser.
In einem abschließenden Schritt wird ein Induktionskochfeld unter der Kochfeldmarkierung der Scheibe angebracht. Der Ausdruck "angebracht" beinhaltet dabei sowohl eine direkte Befestigung an der Scheibe, beispielsweise durch geeignete Kleber, als auch die nicht feste Positionierung unter der Scheibe. Der Abstand kann dabei vom Wirkradius des Induktionskochfelds bestimmt werden.In a final step, an induction hob is placed under the hob mark of the pane. The term "attached" includes both a direct attachment to the disc, for example by suitable adhesive, as well as the non-fixed positioning under the disc. The distance can be determined by the effective radius of the induction hob.
Das Verfahren beinhaltet bevorzugt das Aufbringen einer kratzfesten Beschichtung auf der Glasscheibe. Die kratzfeste Beschichtung wird besonders bevorzugt auf der Glasoberseite angebracht, d.h. auf der dem Induktionskochfeld abgewandten Seite aufgebracht.The method preferably includes applying a scratch-resistant coating to the glass sheet. The scratch-resistant coating is more preferably applied to the glass top, i. applied on the side facing away from the induction hob.
Das Verfahren beinhaltet bevorzugt das Aufbringen einer hydrophoben, schmutzabweisenden Beschichtung auf der Glasscheibe. Die hydrophobe, schmutzabweisende Beschichtung wird besonders bevorzugt auf der Glassoberseite angebracht, d.h. auf der dem Induktionskochfeld abgewandten Seite aufgebracht.The method preferably includes applying a hydrophobic, stain-resistant coating to the glass sheet. The hydrophobic, soil-repellent coating is more preferably applied to the glass top, i. applied on the side facing away from the induction hob.
Das Verfahren beinhaltet bevorzugt das Aufbringen einer kratzfesten Beschichtung auf der Glasscheibe und das anschließende Aufbringen einer hydrophoben, schmutzabweisenden Beschichtung. Damit ergibt sich der Schichtaufbau Glasscheibe, kratzfeste Beschichtung und hydrophobe, schmutzabweisende Beschichtung als Deckschicht. Die Beschichtung wird besonders bevorzugt auf der Glasoberseite, d.h. auf der dem Induktionskochfeld abgewandten Seite, aufgebracht.The method preferably includes applying a scratch-resistant coating to the glass sheet and then applying a hydrophobic, stain-resistant coating. This results in the layer structure glass pane, scratch-resistant coating and hydrophobic, dirt-repellent coating as a topcoat. The coating is particularly preferred on the glass top, i. on the side facing away from the induction hob, applied.
