  • the second part can be implemented in a very simple manner in terms of construction and production technology, with different light-optical functionalities being made possible by means of the coarse structure on the one side and the fine structure on the other side.
  • the preferred embodiment of this development also has the further advantage that the size of the elements Rough structure can be adapted to the luminous flux that decreases when passing through the second part due to the progressive light extraction. This can be implemented particularly easily using the particularly preferred embodiment of this development.
  • An advantageous development of the last-mentioned development of the cooking chamber light according to the invention provides that the coarse structure is designed to deflect the light towards the interior of the cooking chamber and the fine structure is designed to deflect the light towards the rear wall of the cooking chamber.
  • the respective structure can be specifically adapted to the requirements of the corresponding light-optical function.
  • the respective coarse structure is designed as an outer surface of the rear wall which is arranged obliquely relative to the light coupled into the second part, preferably that the respective coarse structure is designed as a single slope. This significantly simplifies the construction and production of the rough structure. This applies in particular to the preferred embodiment of this development.
  • the respective fine structure is designed as a plurality of outer surfaces of the rear wall which are arranged obliquely relative to the light output surface in a horizontal section through the second part, preferably that the respective fine structure is designed as a sawtooth structure is. In this way, the construction and production of the fine structure is also significantly simplified. This applies in particular to the preferred embodiment of this development.
  • the light decoupling surface is formed on a front wall of the second part opposite the rear wall, preferably that the front wall has a light decoupling structure, particularly preferably that the light decoupling structure is designed as a honeycomb structure.
  • the rear wall with the light deflection means on one side and the light decoupling surface for decoupling the light from the second part on the other side are assigned to one another in a particularly advantageous light-optical manner.
  • a substantially homogeneous appearance of the light decoupling surface is made possible, so that, for example, small cracks in the second part, which are caused by cooling of the second part during its production or the like, are concealed by means of the light decoupling structure.
  • Particularly advantageous for this is the design of the light decoupling structure as a honeycomb structure.
  • the cooking appliance according to the invention can be freely selected within wide suitable limits.
  • An advantageous development of the cooking appliance according to the invention provides that the light source of the cooking space lamp is arranged above the cooking space and the second part of the light guide of the cooking space light is arranged to the side of the cooking space in the housing.
  • the light source and corresponding electronics of the cooking chamber light outside the aforementioned hot area in the aforementioned cold area of the cooking appliance.
  • the light source and its electronics can be combined with other electronics of the cooking appliance, which are usually arranged above the cooking space. Accordingly, there are structural advantages which can, for example, lead to a reduction in the number of components and/or to a saving of installation space.
