Definitions

  • the present invention relates to a door hinge for a door of a domestic appliance, in particular for an oven door of a cooking oven. Further, the present invention relates to a door for a domestic appliance, in particular an oven door for a cooking oven. Moreover, the present invention relates to a domestic appliance, in particular a cooking oven.
  • An oven door acts as a thermal barrier in order to keep the heat within an oven cavity during the cooking process.
  • a gasket is provided for sealing a gap between the oven door and the oven cavity.
  • a transparent oven door allows the user supervising the progress of the food stuff being cooked in the oven cavity.
  • the oven door is usually supported by door hinges. Said door hinges allow a pivoting of the oven door relative to the oven cavity.
  • the pivoting of a so-called drop-down door is performed along a vertical direction, i.e. the pivoting axis extends horizontally.
  • the pivoting of a so-called side-opening door is performed along a horizontal direction, i.e. the pivoting axis extends vertically.
  • the mechanical force for the movement of the oven door is generated by the user and applied to the oven door via a door handle, a recessed grip or another comparable device.
  • FIG 7 illustrates a schematic sectional side view of the oven door 30 for the cooking oven 40 according to the prior art in a partially opened state.

  • the moveable hinge part 14 and the moveable pin element 20 may be formed as a single-piece part.
  • the moveable pin element 20 is received by a pair of elongated holes 22 of the stationary hinge part 12.
  • the moveable pin element 20 is slidable perpendicular to its longitudinal axis between two limit stops of the elongated holes 22. Inner limit stops of the elongated holes 22 face the chassis of the cooking oven 40, while outer limit stops of the elongated holes 22 are averted from said chassis.
  • the moveable hinge part 14 includes a pivotable guide edge 28.
  • the pivotable guide edge 28 is in contact with the stationary pin element 18 of the stationary hinge part 12. The cooperation of the pivotable guide edge 28 and the stationary pin element 18 prevents that the moveable hinge part 14 is pivotable relative to the stationary hinge part 12 between the closed state and the intermediate state of the door hinge 10.
  • the pivotable guide edge 28 is in contact with the stationary pin element 18 of the stationary hinge part 12.
  • the interaction of the pivotable guide edge 28 and the stationary pin element 18 forces the moveable hinge part 14 to pivot relative to the stationary hinge part 12 between the closed state and the intermediate state of the door hinge 10.
