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.

Cleaning chemical assembly, cleaning chemical modular system, and cooking appliance

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.
