Definitions

  • the present invention relates to an oven door according to claim 1. Further, the present invention relates to a method for producing an oven door according to claim 1 1.
  • An oven requires a window in the oven door, so that the user is able to look inside the oven without opening the oven door.
  • the oven door further should be made of temperature-resistant materials.
  • a typical oven door comprises one or more transparent door panels, which are made of glass or transparent plastics.
  • the door panel is integrated in a door frame.
  • the door frame consists of several frame parts and each frame part is provided for one circumferential side of the door panel.
  • DE 10 2004 002 470 Al discloses an oven door with a door frame.
  • the door frame includes an injection moulded part enclosing all four circumferential sides of a door panel. In order to attach a further door panel, additional fixing elements are required.
  • the oven door cannot be completely disassembled without destroying the door frame.
  • DE 102 02 144 Al discloses an oven door with a door frame enclosing all four circumferential sides of a door panel.
  • the door frame includes also an injection moulded part. Further door panels must be glued onto the outer side of the door frames.
  • the oven door includes at least one door frame and at least one door panel, wherein
  • the door panel is integrated within the door frame
  • the door frame grips directly an outer portion of at least one door panel on three circumferential sides of said door panel, - the door frame is formed as a one-piece injection moulded part made of a temperature-resistant material, and
  • the door panel is made of a temperature-resistant material and at least partially of a transparent material.
  • the core idea of the present invention is on the one hand, that the door frame is formed as the one-piece injection moulded part, and on the other hand, that the door frame grips directly the outer portion of the door panel on three circumferential sides. This allows a reduced production process by using the injection moulding.
  • the door frame is produced around the door panel by a single step.
  • the door panel is fixed within the door frame by the same single step.
  • the door frame and the door panel form a compact unit.

  • the hole or the holes, respectively, allow an additional fastening between the door frame and the door panel.
  • the hole is arranged in a corner of the door panel.
  • the door panel is formed as a substantially rectangular sheet.
  • the door frame has a U-shaped form and grips the outer portion of the door panel on three circumferential sides of said door panel with said U-shaped form.
  • This structure allows a simple production process, in particular for the step of injection moulding.
  • the door panel can be separated in an easy way the from the door frame by moving the door panel through the open side of the U-shaped door frame at a later time.
  • At each end portion of the U-shaped door frame at least one of the holes may be arranged in the door panel.
  • the holes in this position increase the stability of the oven door.
  • the door panel grips the outer portion of the door panel on each circumferential side of said door panel.
  • the door frame is a closed frame around the door panel.
  • the hole or the holes, respectively, in the door panel are optional.
  • the door panel is made of glass.
  • the door panel may be made of transparent plastics.
  • the oven door has a very low weight.
  • the door frame is formed of a polymer material, preferably a single polymer material. Further, the door frame may comprise at least one portion, which is formed as a profile part. The profile part allows a low weight and requires less material.
  • the outer portion of the door frame is formed as one or more profile parts. This allows an arbitrary contour of the oven door.
  • the oven door is provided for a cooking oven, preferably for domestic use.
  • the door panel may comprise at least one shied grid in order to screen electromagnetic waves.
  • the oven door also may be provided for a microwave oven.
  • the door panel covers the cross-section of the inner space of the microwave oven.
  • the object of the present invention is further achieved by the method ac- cording to claim 11.
  • the inventive method for producing an oven door with at least one door frame and at least one door panel includes the following steps:
  • the door panel made of a temperature-resistant material and at least partially of a transparent material
  • the door frame is produced around the door panel by a single step.
  • the door panel is fixed within the door frame by the same single step.
  • the door frame and the door panel form a compact unit.
  • the method is provided for producing the oven door described above.
