Definitions

  • the invention relates to an oven heating with at least one electrical heating resistor to be arranged outside the oven muffle on the outside of a substantially closed muffle wall, which is arranged on an insulation support.
  • Known heaters arranged outside the oven muffle generally have at least one heating resistor, which is embedded in flexible insulation material or in a solid molded body on insulation material and is very close to the associated wall of the muffle, so that the heat by heat conduction on the Muffle wall and from this is transferred to the inside of the muffle.
  • Such heaters have a relatively high response, a low efficiency and are not suitable for preparing food by grilling.
  • the invention has for its object to provide an oven heating that allows quick heating of the oven and temperature changes in the oven in a simple manner with little inertia.
  • an oven heating of the type described in the introduction provides for it to have at least one radiant heater and for the muffle wall to be designed as a radiation window in the region of its beam path.
  • the interior of the oven is thus heated up by the radiation-permeable radiation window due to the heat radiation from the radiant heater, so that the desired working temperature can be reached extremely quickly, for example, when the oven is cold.
  • the insulation support provided anyway for the essentially exposed electrical heating resistor can at the same time be used as thermal insulation for the associated muffle wall, so that separate insulation can be dispensed with.
  • the radiation window which can be designed to be translucent or transparent, also makes it possible to grill with the same radiant heater, which is also provided for the normal heating of the oven, without a separate grill heater to be arranged within the muffle. Since the heating resistor of the radiant heater generally glows relatively brightly during operation, the radiation window also illuminates the interior of the muffle without the need for a separate lighting device.
  • the radiation window or the like is through a plate made of glass ceramic. formed and preferably on the flange profiles surrounding them, made of sheet metal or the like. existing wall parts of the associated muffle wall attached, so that there are very smooth inner muffle surfaces despite the separately used radiation window, which both facilitate cleaning and exclude the risk of injury from protruding edges.
  • the wall parts adjoining the radiation window can be formed in one piece with at least one muffle wall lying transversely or at right angles thereto, it also being conceivable that both side walls, the top wall and the bottom wall of the muffle are formed by a single sheet metal part.
  • the heating is particularly suitable as top heat for arrangement in the top wall of the muffle and / or as bottom heat for arrangement in the bottom wall of the muffle.
  • a further improvement in the efficiency of the heating can be achieved in that an edge, in particular an edge of the insulation support surrounding the heating resistor, is placed under pressure and thus practically sealed against the radiation window and / or against parts of this radiation window.
  • the radiation window can also advantageously be damped against impact loads and thus protected against damage.
  • the insulation support in the area of its heated zone that is to say in the field in which the heating resistor (s) are arranged, has at least one, in particular web-shaped, projection on its outer edge for support on the outside of the radiation window.
  • the outer edge of the insulation carrier is expediently graduated across its width in order to achieve the largest possible area of plant, and instead or in addition to this, it has a groove-shaped receptacle for an insulating seal, a shock-absorbing insert or the like. can have, so that there is a very tightly closed system on the outside of the muffle wall.
  • the insulation support which is preferably plate-shaped in the area of the heating resistor, on the outside and / or inside with stiffening profiles, in particular with ribs, depressions provided around its center and directed against it. the like is provided.
  • the insulation support has a holder which, in view of the heating resistor, preferably occupies only a part of its base area and, for example, in the manner of a reinforcement, a cleaning edge or the like. is partially embedded in the pressed insulation material.
  • the insulation support therefore does not need a bowl-shaped holder made of sheet metal or the like, which completely accommodates it, but only in individual areas, namely, for example, in the area of the attachment of fastening elements, in the area of corner edges to be protected or in the area of functional parts to be attached or connected, such as temperature sensors, mounting parts, while it can otherwise be exposed between the muffle and the oven outer housing.
  • the bracket surrounds the insulation support expediently where when it does not have to protrude over its outer peripheral surface, so that there is a very compact design.
  • spring members are expediently provided, which act on the one hand on the muffle, in particular directly adjacent to the radiation window, and on the other hand on the radiant heater, in particular on its rear side.
  • These spring members can be simple leg springs, which are attached to the outside of the oven muffle and from there are guided via a tension member to the back of the radiant heater, against which they rest resiliently and against which they may be secured in position by interlocking projections and openings relative to the radiant heater.

  • the insulation carrier consists essentially of compressed vermiculite.
