Definitions

  • the invention relates to a door for a device, in particular a cooking oven, preferably for the household.
  • Out EP 0 010 829 B1 is a viewing window unit for a oven door known with several, each mounted in receiving grooves and arranged parallel to each other glass sheets.
  • the viewing window unit is installed as a module in the oven door by means of screws. Separate removal of the individual glass panes from the door is not possible.
  • the glass panes are of different sizes and held in differently spaced receiving grooves.
  • the DE 26 54 017 A1 discloses a self-contained window unit for installation in a oven door with two glass panes arranged parallel to one another.
  • the front, arranged on the outside of the door glass is removable from the door, in which it is pressed against a spring element and then taken out of the door.
  • the other glass pane is firmly mounted. It is in the DE 26 54 017 A1 embodiments disclosed in which the two glass sheets and the associated holding means have different dimensions.
  • Out DE 41 18 800 A1 is a door for a laboratory cabinet, in particular a heating cabinet, known with a transparent outer pane, a transparent intermediate pane and a transparent inner pane.
  • the washer is held by the outer pane and the inner pane respectively by fixed to the door frame spacers made of sheet metal at a distance.
  • the three discs have identical geometric dimensions and are not expandable after their installation without much effort.
  • a oven door is known with two carrier profiles that form the two vertical door edges.
  • the two carrier profiles On sides facing each other, the two carrier profiles have a plurality of vertical receiving grooves into which two glass panes corresponding in width and height to the door dimensions are inserted.
  • One of the two glass panes forms the outer pane of the door and is wider than the other glass pane that forms the inner pane of the door.
  • the inner pane is designed to be higher than the outer pane.
  • Up and down the upper and lower edge of the door forming end strips are attached to the support profiles by means of screws which close the cavities of the support profiles up and down and thereby hold the inserted glass sheets against displacement in the grooves.
  • the glass panes By removing a closing strip, the glass panes can be replaced in case of glass breakage.
  • further receiving grooves are provided, in which, if necessary, further plates, such as additional blasting protection plates, for example, perforated metal sheet or the like, can be inserted.
  • the additional grooves at the out of the DE-GM 77 36 544 known door have the same distances from each other as provided for the inner pane receiving grooves. This can be confused during reassembly after removing the inner pane and the additional installation of another glass pane, the two discs. This is particularly disadvantageous in cases where the inner pane has a different heat radiation reflectivity than the intermediate pane. To intensify the reflection of exiting from the oven muffle heat radiation namely the inner pane is often provided with a heat radiation reflecting coating that is significantly less effective if the inner pane is accidentally installed in the intermediate position and already a large proportion of the heat radiation has passed into the door interior and about the components of the door can pass through heat conduction to the outside.
  • DE 197 38 506 C1 discloses a door for a household appliance, in particular for a Mosgarofen, with an outer pane, two attached to the outer pane support members and arranged on the two support elements on the side remote from the outer pane side inner pane.

  • the washer can be mounted in the door with the inner pane removed.
  • the Inner pane and the washer have different geometric dimensions. However, since the washer is supported on the inner pane, the washer is not held in the door with the inner pane removed and therefore can fall out of the door.
  • the EP 0 811 806 A1 discloses a door for closing the oven muffle of a baking and roasting oven with a front panel forming plate of glass or vitreous material (outer pane) and one of the oven muffle facing viewing window (inner pane).
  • outer pane On the outer pane two columnar, formed from sheet metal profile parts and parallel to each other extending support elements are glued to the inside.

  • the entire holding element is a continuous molding and can therefore be mounted in an assembly step on the associated support member. This reduces assembly times for the door.
  • At least one of the bearing surfaces is formed by the bottom surface of a receiving groove formed in the retaining element.
  • the term receiving groove is to be understood in the broadest sense here and in the following, all structures except the said bottom surface on which the recorded (imported) door edge edge surface, also have lateral boundaries for the door glass, where the recorded door glass strikes or rests , The bottom surface and the lateral boundaries need not be contiguous, even if such a coherent design is preferred and is often understood in the narrower sense of a receiving groove.
  • Receiving grooves are provided on the holding elements preferably at least for holding those door glass or door glass, which is or are to be arranged in the space between the inner sides of the support elements. The inserted and held in the space between the support elements in the receiving grooves intermediate discs can thus not fall out of the door even when removed or not yet inserted, to be positioned on the front of the support elements inner pane.

  • a locking or clamping has the advantage that no additional, separate fastening means such as screws or the like are needed.
  • each door pane is cantilevered between the holding elements. This further reduces thermal bridges and saves material for the retaining elements.
  • the holding elements are each arranged at one end of the carrier elements and at the opposite ends of the carrier elements, a carrier strip connected to the two carrier elements is arranged with receiving means for the door panes.
  • the receiving means may also comprise receiving grooves and / or restoring devices.
