  • the design of the door operating mechanism can be freely selected within wide, suitable limits.
  • An advantageous further development of the cooking appliance according to the invention provides that the door is arranged pivotably about an axis of rotation arranged on the housing, wherein the first drive unit is arranged on the housing on a side of the cooking chamber opening opposite the axis of rotation and the second drive unit is connected to the door in a force-transmitting manner on the axis of rotation. In this way, for example, the effort required to move the door into its closed position is reduced, so that the first drive unit can be motorized more weakly and thus more cost-effectively.
  • the first drive unit has a base plate and a slide, the first drive unit being fastened to the housing by means of the base plate and the slide being held movably on the base plate.
  • the first drive unit is implemented in a structurally particularly simple manner.
