Definitions

  • the present invention relates to a cooking oven comprising an oven muffle having muffle walls which define a cooking chamber and at least one heating element which is fixed to at least one of the muffle walls by means of at least one fixing element according to the preamble of claim 1.
  • Known cooking ovens comprise a cooking chamber being defined by the walls of an oven muffle.
  • heating elements are provided within and/or outside of the cooking chamber.
  • the heating elements are arranged in a certain distance to the oven muffle walls.
  • the heating element can be guided at least partly through the oven muffle walls, such that the heating section of the heating element extends within the interior side of the oven muffle.
  • the oven muffle is assembled from several muffle parts manufactured in deep-drawing processes and cutting processes, wherein the muffle parts are welded together afterwards. Due to the deep-drawing, cutting and - if applicable - enamelling processes the muffle parts are manufactured within relatively large tolerances which cause a certain bandwidth of geometrical variations from oven muffle to oven muffle. Said geometrical variations cause difficulties in subsequent manufacturing steps such as mounting and/or installation of a heating element.
  • DE 195 22 545 A1 discloses a microwave oven including a flat electric heating element.
  • the heating element is pivoting inside the oven cavity, so that the heating element is arrangeable either horizontally below a top wall of the oven cavity or vertically in front of a rear wall of the oven cavity.
  • a connector encloses the terminal ends of the heating element.
  • the connector is pivoting within a supporting device formed as a cylinder barrel. The supporting device is attached at an outer side of the oven cavity wall and covers an aperture in said oven cavity wall.
  • US 3,296,417 discloses a sheathed electric heating element for removable connection to an apertured wall of an oven cavity.
  • a mounting plate is adapted to be secured over the aperture in the oven wall.
