Description
Die Erfindung bezieht sich auf einen elektrischen Ofen mit in einer Muffel angeordneten Heizwiderständen, bei dem zwischen den den Ofenraum durchsetzenden Heizstäben Platten, Stäbe oder Roste angeordnet sind, welche so weit über die Widerstände hinausragen, daß die aufgelegten Gegenstände die Widerstände nicht beschädigen können. Die Erfindung besteht darin, daß die Platten, Stäbe oder ίο Roste lose eingestellt sind und von den etwa in den Muffelraum hineinragenden Durchführungsrohren gegen Umfallen gesichert werden. Die Erfindung ist in der Zeichnung dar- ' gestellt.The invention relates to an electric furnace with arranged in a muffle Heating resistors, with plates between the heating rods penetrating the furnace chamber, Bars or grids are arranged, which protrude so far beyond the resistors that the placed objects cannot damage the resistors. The invention consists in the fact that the plates, rods or ίο grids are loosely set and from the approximately in the duct pipes protruding into the muffle chamber are secured against falling over. The invention is shown in the drawing.

α ist die Muffel, b sind die Widerstände. Diese liegen innerhalb der Ofenwandungen in Durchführungsrohren c, dagegen im Muffelraum frei. Zwischen sie sind Platten d, Stäbe oder Roste lose eingestellt, die so weit in den Muffelraum α hineinragen, d. h. so hoch über die Widerstände b hinausragen, daß die aufgelegten Gegenstände die Widerstände nicht α is the muffle, b are the resistances. These lie inside the furnace walls in ducts c, but are exposed in the muffle chamber. Between them, plates d, bars or grids are loosely set, which protrude so far into the muffle space α, ie protrude so high above the resistors b that the objects placed on them do not pass the resistors

You grasp those of them enclosed spaces, in which the resistances lie, against the muffle ß completely open, so that they allow a completely free passage of the heat into the muffle space, which is achieved at the same time Bringing distillers into close proximity to the resistances.
Die Durchführungsrohre c, in welchen dieThe bushing c, in which the
ίο Widerstände innerhalb der Ofenwandungen liegen, sind gegen den Muffelraum α etwas verlängert, d. h. sie ragen etwas in den Muffelraum vor. Hierdurch wird den Platten ei ein entsprechender Halt und eine Sicherung gegen Umfallen gegeben und zugleich erreicht, die Platten auch während des Betriebes durch die Schlitze e zwischen den Durchführungsrohren seitlich leicht herausziehen und auswechseln zu können.ίο Resistances are within the furnace walls, are somewhat extended towards the muffle space α, ie they protrude somewhat into the muffle space. As a result, the plates ei are given a corresponding hold and protection against falling over and at the same time the plates can be easily pulled out laterally through the slots e between the ducts and replaced during operation.
