Abstract: A control box for a cooking appliance is described, having a housing in which at least one steam inlet, at least one water nozzle, a steam outlet, and at least one cleaning agent inlet. The cleaning agent inlet is arranged between the steam inlet and the steam outlet with respect to a flow path of the steam. A cooking appliance having a control box also is described.

Abstract: A cleaning chemical assembly has a collection container, a pump, two ports for storage containers that contain the same cleaning chemical, and a switchover valve that can be switched between a first state, in which the pump can pump liquid from the collection container to the storage container connected to the first one of the two ports while the second port is disconnected in a liquid-tight manner, and a second state, in which the pump can pump liquid from the collection container to the storage container connected to the second one of the two ports while the first port is disconnected in a liquid-tight manner. A sensor is provided that can be used to detect whether one of the storage containers is empty.

Abstract: A cleaning chemical assembly for a cooking appliance has a collection container, a pump, at least two ports for storage containers that contain different cleaning chemicals, and at least one device for identifying the cleaning chemical in the respective storage container. The device for identifying the cleaning chemical is a switching element that is designed to cooperate with a mechanical coding on the respective storage container. The switching element includes a plurality of microswitches at the ports.

Abstract: A method for identifying a degree of soiling of an interior of a cooking appliance, in particular of the cooking chamber, during at least one of a cleaning operation and a cooking operation and a method for cleaning such a cooking appliance interior include determining at least one parameter of a liquid and a degree of soiling.
