  Doppelwandiger Bratofen. 



    Die Erfindung betrifft einen Bratofen in Form einer Muffel mit doppelter Wandung und soll im Vergleich zu den bekannten Konstruktionen dieser Art die Wärmeisolierung und damit vor allem den Wirkungsgrad verbessern und das Gewicht sowie die Herstellung kosten vermindern.   
 EMI1.1 
 auf die Innenseiten der beiden Wandungen aufgetragen werden, während zwischen diesen beiden Schichten noch ein Luftzwischenraum verbleibt. Hiedurch wird gleichzeitig jeder metallische Kontakt zwischen innerer und äusserer Muffel vermieden. 



   In der Zeichnung ist Fig. 1 eine perspektivische Ansicht mit Schnitt nach der 
 EMI1.2 
 der Fig.   l.   



   Als Ausführungsbeispiel ist ein Bratofen in Form einer doppelwandigen   Muffel dar-   gestellt. Das Gerüst bilden zwei Tragrahmen a mit vorspringenden Rippen b. Die beiden
Wandungen   c c, aus Biech   sind auf ihren Innenseiten mit   wärmeisolierenden   Schichten d versehen und sind unter Zwischenlage dieser Schichten auf den Rippen b befestigt, bei- spielsweise mittels durchgehender Bolzen e. Die Blechwandungen   Ci,   c2 sind nicht ganz bis an die Rahmen a herangeführt, sondern es sind   Zwischenräume   z   dazwischengelassen  
Der Luftraum h zwischen den beiden Wandungen kann durch Streifen aus Isoliermaterial in kleinere Räume unterteilt werden, um den   Wärmeausgleich   durch innere Luftströmung zu verhindern."   PATENT.

   ANSPRÜCHE :  
1. Doppelwandiger Bratofen in Form einer Muffel, gekennzeichnet durch Trag- arme (a) mit vorspringenden Rippen (b), auf denen die mit wärmeisolierenden Schichten (d) auf ihren Innenseiten überzogenen Wandungen (c) unter Zwischenlage dieser Schichten befestigt sind.

  Double-walled roasting oven.



    The invention relates to a roasting oven in the form of a muffle with double walls and, compared to the known constructions of this type, is intended to improve the thermal insulation and thus above all the efficiency and reduce the weight and production costs.
 EMI1.1
 can be applied to the inside of the two walls while an air gap remains between these two layers. This simultaneously avoids any metallic contact between the inner and outer muffle.



   In the drawing, FIG. 1 is a perspective view with section according to FIG
 EMI1.2
 of Fig. l.



   A roasting oven in the form of a double-walled muffle is shown as an exemplary embodiment. The frame is formed by two support frames a with projecting ribs b. The two
Walls c c, made of Biech are provided on their insides with heat-insulating layers d and are attached to the ribs b with these layers in between, for example by means of through bolts e. The sheet metal walls Ci, c2 are not brought right up to the frame a, but spaces z are left between them
The air space h between the two walls can be divided into smaller spaces by strips of insulating material in order to prevent the heat from being equalized by the internal air flow. "PATENT.

   EXPECTATIONS :
1. Double-walled roasting oven in the form of a muffle, characterized by support arms (a) with protruding ribs (b) on which the walls (c) coated with heat-insulating layers (d) on their insides are attached with the interposition of these layers.
