In particular, the cleaning apparatus is a steam cleaning apparatus, the cleaning agent is steam, the nozzle is a steam nozzle, and the hand set is a steam gun. The steam allows an effective cleaning of the inner sides of the oven cavity and oven door. For generating the steam the cooking oven may comprise a steam generator arranged inside the cooking oven and connected to the steam nozzle.
In particular, the cooking oven comprises a water reservoir connected to the steam generator.
Further, the steam generator and/or the water reservoir may be connected or connectable to an external water supply. If the steam generator is directly connected to the water sup¬ ply, then the water reservoir is not implicitly necessary.
Preferably, the nozzle is arranged at an inner side wall of the oven cavity. The nozzle at the inner side wall allows an easy access to said nozzle by the user.
The cleaning apparatus may be provided for cleaning the in¬ ner sides of the oven cavity and/or the oven door.
Moreover, the cooking oven may comprise at least one sensor element for detecting, if the flexible pipe is connected to the nozzle.
The hand set may include a jet for distributing the clean¬ ing agent.
In particular, the hand set includes an elongated grip por¬ tion.
Preferably, the shape of the grip portion is adapted to the inner side of the human hand. The axes of the grip portion and the jet may form an obtuse angle .
