Abstract
Description
Die vorliegende Erfindung betrifft einen Backofen gemäß dem Oberbegriff des Patentanspruches 1, wie er aus der JP-A-57120033 bekannt ist.The present invention relates to a baking oven according to the preamble of the claim 1, as known from JP-A-57120033.
Ein derartiger Backofen ist allgemein bekannt, wobei die Backofenmuffel mit einer Emailschicht versehen ist. Die Emailbeschichtung dient zum einen als Antikorrosionsschicht und zum anderen als Antioxidationsschicht. Weiterhin wird durch die Emailschicht die Reinigbarkeit der Backofenmuffel verbessert und die Oberflächenhärte vergrößert. Zuletzt wird durch das Email die Optik der Backofenmuffel bestimmt. Diese Funktionen werden durch das Email bei Schichtstärken von typisch 100 bis 200 µm realisiert. Nachteilig an derartigen Schutzschichten aus Email sind insbesondere deren Sprödigkeit und die durch die unterschiedlichen Ausdehnungskoeffizienten von Email und Muffelmaterial entstehenden Zug- und Druckspannungen, die zu Bauteilverformungen, Rissen oder Abplatzem des Emails führen können.Such an oven is well known, the oven muffle with an enamel layer is provided. The enamel coating serves as an anti-corrosion layer and on the other hand as an antioxidant layer. Furthermore, through the enamel layer the Improved cleanability of the oven muffle and increases the surface hardness. Last the appearance of the oven muffle is determined by the enamel. These functions will be implemented by the enamel at layer thicknesses of typically 100 to 200 microns. Disadvantageous such protective layers of enamel are in particular their brittleness and by the different coefficients of expansion of enamel and muffle material resulting Tensile and compressive stresses that lead to component deformation, cracks or flaking of the email.
Aufgabe der vorliegenden Erfindung ist es deshalb, bei einem Backofen nach dem Oberbegriff des Patentanspruches 1 die Gebrauchseigenschaften der Backofenmuffel zu verbessern.Object of the present invention is therefore, in an oven according to the preamble of claim 1, the performance characteristics of the oven muffle improve.
Erfindungsgemäß ist dies bei einem Backofen mit den Merkmalen des Patentanspruches
1 erreicht. Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist die
Schutzschicht als Sol-Gel-Hartschicht realisiert. Auf der Sol-Gel-Hartschicht
ist eine Sol-Gel-Funktionalschicht vorgesehen, die verschiedene Bereiche
der Muffelwände mit besonderen Eigenschaften ausstattet. Diese Eigenschaften
können beispielsweise sein, eine besonders einfache Reinigbarkeit, ein besonderes
Gleitverhalten oder katalytische Eigenschaften. Vorteilhafterweise ist die Funktionalschicht
als etwa 10 µm, insbesondere etwa 2 bis 3 µm starke Schicht realisiert. Aufgrund der Sol-Gel-Technik
verfügen die aufgebrachten Schichten trotz ihrer geringen Dicke sowohl aufeinander
als auch auf dem Metall über eine große Stabilität und ein großes Anhaftvermögen.
Die Stärke der Schutzschicht ist geringer als etwa 30 µm, insbesondere geringer als
20 µm und bevorzugter Weise zwischen etwa 5 und 10 µm ist. Infolge der geringen
Schichtstärke treten in der Muffelwand nur geringe Spannungen auf. Weiterhin ist eine
sehr gute Wärmeleitung von den Heizelementen bzw. der Muffelwand zum Muffelinneren
sichergestellt und ist eine geringe Rißanfälligkeit der Schutzschicht bzw. eine geringe
Wahrscheinlichkeit von Abplatzem realisiert. Diese dünne Schutzschicht stellt einen ausreichenden
Korrosions- und Oxidationsschutz sowie einen harten Oberflächenschutz für
das Metall dar.This is achieved in an oven with the features of claim 1 according to the invention. According to the characterizing part of claim 1, the protective layer is realized as a sol-gel hard layer. On the sol-gel hard layer, a sol-gel functional layer is provided which provides different areas of the muffle walls with special properties. These properties may be, for example, a particularly simple cleanability, a special sliding behavior or catalytic properties. Advantageously, the functional layer is realized as a layer about 10 μm, in particular about 2 to 3 μm thick. Due to the sol-gel technique, the deposited layers, despite their small thickness both on each other and on the metal have a high stability and a high adhesion.
The thickness of the protective layer is less than about 30 microns, especially less than 20 microns and more preferably between about 5 and 10 microns. Due to the low layer thickness occur in the muffle wall only low voltages. Furthermore, a very good heat conduction from the heating elements or the muffle wall to the muffle interior is ensured and a low susceptibility to cracking of the protective layer or a low probability of chipping is realized. This thin protective layer provides adequate corrosion and oxidation protection as well as hard surface protection for the metal.
Derartig dünne Schutzschichten können verfahrenstechnisch einfach bevorzugterweise in Sol-Gel-Technik realisiert sein. Dabei ist die Sol-Gel-Schicht beispielsweise in einem einfachen Tauchverfahren auf die Muffelwände aufbringbar. Insbesondere sind bei der Sol-Gel-Technik die im Vergleich zur Emailierungstechnik niedrigen Einbrenntemperaturen von etwa 450 bis 500 °C günstig. Auch sind die aufgebrachten Sol-Gel-Schichten für die bei Garvorgängen typischen Temperaturen geeignet. Bevorzugter Weise besitzt die Hartschicht eine Stärke von 5 bis 10 µm.Such thin protective layers can procedurally simple, preferably in Sol-gel technology be realized. The sol-gel layer is for example in a simple Dipping method applied to the muffle walls. In particular, in the sol-gel technique the low stoving temperatures compared to the enamelling technique from about 450 to 500 ° C low. Also, the applied sol-gel layers are for the during cooking typical temperatures suitable. The hard layer preferably has a thickness of 5 to 10 microns.
Gemäß einer bevorzugten Ausführungsform ist die Schutzschicht transparent und dient die Innenseite der Muffelwand als Reflektor. Dies ist insbesondere dann günstig, wenn mit Hilfe von Wärmestrahlung im Infrarotbereich oder im sichtbaren Licht-Bereich gegart wird. Derartige Transparentschichten sind als Sol-Gel-Schichten problemlos darstellbar.According to a preferred embodiment, the protective layer is transparent and serves the inside of the muffle wall as a reflector. This is particularly favorable when cooked with the help of heat radiation in the infrared range or in the visible light range becomes. Such transparent layers can be easily displayed as sol-gel layers.
Falls die Backofenmuffel aus Aluminium besteht, kann die Schutzschicht als anodisierte, insbesondere hartanodisierte Aluminiumoxidschicht realisiert sein. Diese Oxidschicht zeichnet sich insbesondere durch ihre ausgezeichnete Härte und Glätte aus.If the oven muffle is made of aluminum, the protective layer may be anodised, in particular be realized hard anodized aluminum oxide. This oxide layer is characterized in particular by its excellent hardness and smoothness.
Ein besonders guter Wärmeübergang vom Heizelement zur Muffelwand bzw. zum Garraum und eine diesbezüglich hervorragende Wärmeverteilung ist dadurch erreichbar, daß die Muffelwand eine isolierende Schutzschicht im µm-Bereich aufweist, auf der das Heizelement mittels Dickschichttechnik direkt aufgebracht ist. Gegebenenfalls kann das Heizelement auch mit aufwendigeren Beschichtungsverfahren, beispielsweise der Dünnschichttechnik, realisiert sein. A particularly good heat transfer from the heating element to the muffle wall or to the cooking chamber and an excellent heat distribution in this regard is achievable in that the muffle wall has an insulating protective layer in the micron range, on which the heating element is applied directly by means of thick film technology. Optionally, the heating element also with more complex coating processes, for example thin-film technology, be realized.
Aufgrund der dünnen Schutzschichten treten beim Aufheizen der Backofenmuffel trotz der unterschiedlichen Wärmeausdehnungskoeffizienten der Schutzschicht und der Muffelwand lediglich geringe Spannungen in der Backofenmuffel auf. Deshalb kann die Stärke der Muffelwand auch auf beispielsweise etwa 0,4 mm verringert werden.Due to the thin protective layers occur when heating the oven muffle despite the different thermal expansion coefficients of the protective layer and the muffle wall only low voltages in the oven muffle. That's why the strength can be the muffle wall can also be reduced to, for example, about 0.4 mm.
Gemäß einer bevorzugten Ausführungsform ist die Backofenmuffel durch einen Stabilisierungsrahmen von außen abgestützt. Dies ist insbesondere dann wichtig, wenn die Dicke der Muffelwand nur etwa 0,3 bis 0,5 mm beträgt. Durch diese nahezu Halbierung der Wandstärke der Backofenmuffel im Vergleich zum bisher bekannten Stand der Technik werden die Aufheizzeiten und die Wärmeverteilung weiterhin deutlich verbessert. Zudem kann durch die geringe Materialstärke Material eingespart werden. Außerdem wird das Gewicht der Backofenmuffel deutlich reduziert.According to a preferred embodiment, the baking oven muffle is provided by a stabilizing frame supported from the outside. This is especially important when the thickness the muffle wall is only about 0.3 to 0.5 mm. By this almost halving the Wall thickness of the oven muffle compared to the previously known prior art the heating times and the heat distribution will be significantly improved. moreover can be saved by the low material thickness material. Besides, that will Weight of oven muffle significantly reduced.
Gemäß einer bevorzugten Ausführungsform ist der Stabilisierungsrahmen im wesentlichen durch eine Backofenisolation gebildet. Diese muß zum einen ausreichend nachgiebig sein, um die räumliche Vergrößerung der Backofenmuffel beim Aufheizen mitmachen zu können, und zum anderen steif genug sein, um die dünnwandige Backofenmuffel ausreichend stabilisieren zu können. Es zeigen:
- Fig. 1 bis Fig. 4
- in perspektivischen Ansichten von vorne die Backofenmuffel nach verschiedenen Verfahrensschritten zu deren Herstellung.

Fig. 1 zeigt eine quaderförmige Backofenmuffel 1 aus Edelstahl mit fünf Muffelwänden
3. Dies sind die beiden Seitenwände, eine Boden- und eine Deckwand sowie eine
Rückwand. Die Beschickungsöffnung der Backofenmuffel 1 umzieht ein Muffelflansch
5. Die Backofenmuffel 1 ist einstückig in einem Hydroumformverfahren hergestellt. Bei
diesem Tiefziehverfahren weist die Backofenmuffel im Unterschied zu herkömmlichen
mechanisch tiefgezogenen Teilen Mängel, wie ungleichmäßige und große Wanddickenveränderungen,
sichtbare Ziehspuren und einen Ziehwulst, sowie verminderte
Oberflächenqualität und verminderte Formgenauigkeit nicht auf. Mit Hilfe der Sol-Gel-Technologie
werden in einem Tauch- oder Spritzverfahren eine Muffelinnenseite 7 und
eine Muffelaußenseite 9 mit einer Sol-Gel-Schicht 11 beschichtet (Fig. 2). Dabei wird
aus einer Lösung (Sol) durch kontrollierte Kondensationsmethoden ein kolloides System
im Mikrometer-Maßstab (Gel) erzeugt. Dieses Gel wird durch Trocknen infolge
Lösungsmittelentzug verdichtet und anschließend in geeigneter Weise ausgehärtet
bzw. bei einer Temperatur von etwa 450 bis 500°C eingebrannt. Während dieses Prozesses
wird die Sol-Gel-Schicht über chemische Verbindungen mit dem Untergrund
besonders fest verbunden. Die dabei entstehende Sol-Gel-Schicht ist etwa 10 µm dick
und bildet auf der Muffelwand 3 aus Edelstahl beidseitig eine harte Oberfläche mit elektrischen
Isolationseigenschaften. Weiterhin bildet sie einen Anlauf- und Oxidationsschutz
für das Edelstahl. Auf die Sol-Gel-Hartschicht sind in zumindest einem weiteren
Prozeßschritt in Sol-Gel-Technik Funktionalschichten auf verschiedene Bereiche der
Muffelinnenseite 7 aufgebracht. Abhängig vom Ort in der Backofenmuffel 1 sind durch
die Sol-Gel-Funktionalschichten insbesondere Antihaft-, Gleit- und Katalyseeigenschaften
bereitgestellt. Die Sol-Gel-Funktionalschichten haben dabei eine Dicke von
etwa 3 µm. Die aus den beiden Sol-Gel-Schichten 11 gebildete Schutzschicht ist derart
transparent, daß die zur Zubereitung von Speisen relevante Wärmestrahlung im Infrarot-
bzw. im sichtbaren Licht-Bereich die Schutzschicht durchdringen kann und von der
Edelstahloberfläche ins Muffelinnere optimal reflektiert werden kann (Fig. 2). Bei Bedarf
ist auch eine transparente oder deckende Einfärbung der Schichten möglich.Fig. 1 shows a cuboid oven muffle 1 made of stainless steel with five
Auf die Sol-Gel-Hartschicht sind in einem nachfolgenden Verfahrensschritt auf der
Muffelaußenseite 9 mäanderförmige Heizleiter 13 in Dickschichttechnik aufgetragen
(Fig. 3). Aufgrund der besonders dünnen Isolationsschicht zwischen dem Heizleiter 13
und der Muffelwand 3 ist ein besonders günstiger und gleichmäßiger Wärmeübergang
möglich. Die Heizleiter 13 können über Leiteranschlüsse 15 mit elektrischer Spannung
versorgt werden.On the sol-gel hard layer are in a subsequent step on the
Muffle outside 9 meander-
Gemäß Fig. 4 ist die Backofenmuffel 1 schließlich in eine Muffelisolation 17 aus faserfreiem Isolationsmaterial, z.B. Perlite, eingebettet. Durch den Isolationsmantel ist die Backofenmuffel 1, deren Wandstärke lediglich 0,4 mm beträgt, stabilisiert. Weiterhin ist die Isolationsschale 17 ausreichend nachgiebig gestaltet, um bei der thermischen Ausdehnung der Backofenmuffel 1 beim Aufheizen während eines Backvorgangs nicht zu reißen.4, the oven muffle 1 is finally in a muffle insulation 17 of fiber-free Insulation material, e.g. Perlite, embedded. Through the insulation jacket is the oven muffle 1, whose wall thickness is only 0.4 mm, stabilized. Furthermore, the Insulation shell 17 designed sufficiently resilient to thermal expansion the oven muffle 1 during heating during a baking process not to break.
