  • the cooking oven 10 may be arranged within an arbitrary niche.
  • the cooking oven 10 comprises a cooling fan 22 arranged above the oven cavity 12.
  • the cooling fan 22 generates a cooling airflow 24.

  • the first part of the cooling airflow 24 passes the top side of the housing and reaches the cooling fan 22.
  • a second part of the cooling airflow 24 is sucked in beneath the oven door 14 into the space between the housing 18 and the furniture 20.
  • the second part of the cooling airflow 24 passes the bottom side and the rear side of the housing 18 and reaches the cooling fan 22.
  • the cooling airflow 24 is blown out between the oven door 14 and the front panel 16 by the cooling fan 22.
  • the camera 26 is attached at the housing 18.
  • the camera 26 is arranged in the upper rear portion of the housing 18.
  • the camera 26 is spaced from the oven cavity 12.
  • the cooling airflow 24 passes the camera 26, in particular the electronic components of said camera 26.
  • the camera 26 has a direct connection to the cooling airflow 24.
  • the cooling airflow 24 provides convective heat transfer from the camera 26 to the air.
  • a tube e.g. an aluminium tube, may be arranged between the cooling fan 22 and the camera 26 in order to improve the intensity of the cooling airflow 24 at said camera 26.

  • the optical system 28 includes three optical lenses 30.
  • the material of the optical system 28 has a low heat conductivity, a low thermal capacity and a low mass. Thus, the optical system 28 avoids that too much heat would be transferred from the oven cavity 12 to the camera 26.
  • the spaces between the optical lenses 30 are hollow.
  • the shapes of the optical lenses 30 depend on the type of the camera 26, in particular on the type and size of the optical sensor of said camera 26.
  • the cooking oven 10 comprises a protection shield 32.
  • Said protection shield 32 is arranged in front of the optical system 28.
