Definitions

  • the invention relates to a door for a cooking oven.
  • Doors for household ovens are known with a viewing window which is formed by a translucent outer pane and a translucent inner pane and optionally also a translucent intermediate pane arranged between them.
  • DE 197 38 504 C1 discloses a door for a household appliance, in particular a household oven, with a door pane that can be installed and removed.
  • This known door comprises an outer pane to which two column-like support elements made of an enameled steel sheet formed into a profile part are fastened, and an inner pane which is held removably by two receiving devices fastened to the support elements.
  • a spring element is provided in one of the two receiving devices, the other receiving device comprises two corner brackets, each provided for a corner of the inner pane, with a circumferential receiving groove.
  • the inner pane Due to the restoring force of the spring element, the inner pane is pressed into the receiving groove of the second receiving device and held there (locked, fixed). To remove it, the inner pane is simply pressed against the restoring force of the spring element until it emerges from the receiving grooves, and can then simply be removed from the door. In the installed position the inner pane rests on the flat central parts of the two columnar support elements and is pushed along these central parts during assembly or disassembly.
  • DE 197 05 120 A1 discloses a door for closing an oven muffle of an oven with a frame-like, all-round carrier (door frame) made of plastic for enclosing an inner pane, an outer pane and an intermediate pane.
  • the frame-like carrier comprises a frame-like filler plate and lateral edging strips which form a frame wall surrounding a door interior.
  • the frame wall and the filler plate form an integral frame profile part of the frame-like carrier.
  • a bracket is glued to the outer pane by means of an adhesive, to which the frame profile part is fastened by means of a screw.
  • the inner pane is glued to a support surface of the frame profile part facing away from the outer pane.
  • a spacer element which extends into the interior of the door and has a support surface, is formed on the frame profile part.
  • the washer rests on one side on the contact surface of the spacer element. On the opposite side, the washer rests on the retaining bracket on the outer pane via an elastic element.
  • the intermediate pane is clamped between the support surface of the spacer and the elastic element.
  • an elastic element can also be arranged on the support surface provided for the outer pane and on the support surface provided for the intermediate pane.
  • the inner pane of this oven door known from DE 197 05 120 A1 cannot be removed.
  • EP-A-811 806 shows a door for closing the oven muffle of a baking and roasting oven, according to the features in the preamble of claim 1.
  • the invention has for its object to provide a special door for a fermentation oven, preferably for the household, which is easy to assemble.
  • the door for a cooking oven preferably a domestic cooking oven, comprises at least two support elements arranged separately from one another, each of which is formed from a temperature-resistant and mechanically stable (impact-resistant, mechanically tough) polymer material (plastic), and at least one door pane, which is in particular on the door front, that is, on the outside facing away from the oven in the oven (outer pane).
  • holding means holding means
  • fastening means connecting means which are formed in one piece with the associated carrier element (as a common, coherent molded body) and are provided for receiving or fastening the door pane and / or at least one further door component ,
  • the polymer material can in particular be a thermoplastic or also a thermoset with the corresponding thermal and mechanical properties.
  • the molded bodies made from carrier elements and associated receiving means or fastening means are produced as injection molded parts and / or essentially consistently from a polymer material.
  • the additional door components in addition to the door pane can in particular be door hinges and / or further door panes and / or a door handle.
  • Each door pane generally consists of an optically transparent material, in particular a glass or a glass-like material, in order to form a viewing window into the cooking space.
  • At least one spacer is formed on each of the carrier elements in order to maintain a predetermined distance between the remaining surface of the carrier element and one of the door panes mentioned. This leads to a better thermal decoupling of the door pane from the carrier element, since the spacer has a smaller contact surface than the entire carrier element and preferably from a material with low heat conduction.
  • Each spacer is preferably at least partially elastically deformable, in particular by being designed as a resilient element. This dampens force shocks between the door pane and the support element, which can occur during assembly or disassembly of the door pane or when the door moves and is shaken during use (soft mounting of the door pane on the spacer).
  • each spacer is preferably between the associated door pane and the associated carrier element under tension to reduce the rattling noise of the door window.
  • each spacer consists at least on the surface facing the door pane of a slidable material, so that the door pane can be moved on each spacer with a low sliding friction.
  • the spacers can be provided with a sliding layer or even consist of a lubricating plastic such as, for example, a suitable fluorocarbon. Due to the slidability of each spacer, the door window on each spacer can be moved with a low sliding friction and is therefore easy to move. This facilitates the assembly and disassembly of the. Door glass.
  • the mounting or fastening of the door panes and / or other door components is preferably detachable, so that these parts can be dismantled and reassembled from the door, for example for replacement with new parts or for cleaning purposes.
  • the associated receiving means or fastening means on the carrier elements and, if appropriate, corresponding means on the door component are designed accordingly, for example by means of receiving grooves or releasable connections.
  • a preferred type of attachment of one or more door components to the carrier elements is a snap or snap connection.
  • the fastening means preferably comprise snap-on or latching elements which are molded or molded onto the carrier elements and which interact with corresponding snap-on or latching elements on the door pane or the other door component.
  • the choice of material according to the invention is particularly advantageous for the carrier elements, since a snap or snap connection in a plastic is very easy to implement, while this was previously problematic with support elements made of enamelled steel sheet.
  • the connecting elements between The pull-outs and the door can be fastened inside or on the support elements via a snap or snap connection.
  • the door hinges or connecting elements are then resiliently suspended in the carrier elements, with the positive consequence that force shocks which are transmitted from the door hinge (connecting carrier) to the carrier element are dampened.
  • a resilient damping of the hinge suspension or other door connection with the oven can also be realized in combination with another type of fastening, for example by a resilient screw connection, wherein in particular a resilient element with a screw thread can be integrally formed on the support element.
  • At least one elastic (resilient) resetting device is provided, which is at a distance smaller by a predetermined minimum insertion path length from each of a receiving means on each of the support elements than a dimension of the door pane in one direction (for example the pane height in the case of vertical installation and the pane width in the case of horizontal installation) ).
  • the door pane is moved (pressed) at least by the predetermined minimum insertion path length against a restoring force of the restoring device and then positioned so that it is pressed by the restoring force of the restoring device into the receiving means on the carrier elements and thereby between the receiving means and the restoring device is resilient.

In the case of thermosets, on the other hand, a pressing process is generally used to form the shaped bodies.
  • the use of a plastic for the support elements 5 and 6 has the great advantage that different components of the door can be molded on or molded individually or together on the support elements 5 and 6, so that coherent (one-piece) molded bodies are formed, which are in a manufacturing process can be produced. This saves one assembly step each for assembling the components.
