Description

Bratofen mit emaillierten Wänden Sowohl an Bratöfen für Gasherde als auch an solchen für andere Herde werden die Bratofenwände innen und zuweilen auch außen mit einem Emailüberzug versehen, um die Gefahr des Durchrostens Herabzumindern. Es zeigt sich nun, daß solche emaillierten Bratöfen viel größere Wärmeverluste haben als Bratöfen, die mit einem metallischen Spiegel, der ebenfalls als Schutz gegen Rosten dienen kann, versehen sind. Es beruht dies auf dem nachweislich größeren Wärmestrahlungskoeffizienten von keramischer Oberfläche, wozu auch Email zu rechnen ist, als von blanker Metalloberfläche. Urren nun emaillierte Bratöfen ebenfalls des Vorteiles kleinererWärmeverluste teilhaftig werden zu lassen, werden gemäß vorliegender Erfindung die emaillierten Bratofenwände an der Oberfläche mit einem Metallspiegel, beispielsweise mit einem Anstrich von Aluminiumbronze o. dgl., versehen, wodurch einerseits vollständiger Rostschutz durch die Emaillierung erreicht wird, andererseits durch den Metallspiegel die Wärmeverluste nicht größer sind als bei einem nicht emaillierten, mit Metallspiegel versehenen Bratofen.Roasting oven with enamelled walls Both on roasting ovens for gas stoves and The walls of the oven are also on the inside and sometimes also on those for other stoves Provided with an enamel coating on the outside to reduce the risk of rusting through. It now appears that such enamelled roasting ovens have much greater heat losses than roasting ovens that have a metallic mirror that also acts as a protection against Grating can serve, are provided. It is based on the demonstrably larger one Thermal radiation coefficients of ceramic surfaces, including enamel than from a bare metal surface. Enamelled roasting ovens are now also available to share the advantage of smaller heat losses, will become more in accordance with the present Invention of the enamelled oven walls on the surface with a metal mirror, For example, with a paint of aluminum bronze o. The like. Provided, whereby on the one hand, complete rust protection is achieved through the enamelling, on the other hand through the metal mirror the heat losses are not greater than with one enamelled roasting oven with a metal mirror.

Der Email- und dementsprechend auch der Metallüberzug kann entweder nur auf einer Seite (Innen- oder Außenseite) oder auf beiden Seiten des Bratofens angebracht sein. Der Metallüberzug läßt sich statt durch Anstrich z. B. auch durch Einbrennen, Aufspritzen, Elektrolyse usw. herstellen. Die Arten des Aufbringens des Metallüberzugs sind an sich bekannt und bilden nicht den Gegenstand des Schutzbegehrens.The enamel and, accordingly, the metal coating can either only on one side (inside or outside) or on both sides of the oven to be appropriate. The metal coating can be used instead of painting z. B. also through Manufacture baking, spraying, electrolysis, etc. The types of application of the metal coating are known per se and are not the subject of the protection request.
