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 cooking device includes a microwave generator, a cooking chamber wall delimiting a cooking chamber, in which a through opening is provided, and a cooking chamber sieve associated with the through opening. At least one intermediate element is provided between the cooking chamber wall and the cooking chamber sieve, which serves to mount the cooking chamber sieve to the cooking chamber wall. The at least one intermediate element is configured such that the generation of electric arcs between the cooking chamber wall and the cooking chamber sieve is prevented.

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.
