Abstract: The present disclosure relates to a base unit (1) for a food processor for preparing a food (20), wherein the base unit (1) comprises a control (2) and a receiving device (3) for receiving and electrically connecting an interchangeable accessory container (10), wherein the receiving device (3) comprises at least one receiving-side plug-in connection unit (4) for the electrical connection. The receiving-side plug-in connection unit (4) is movable in the mounted state in such a way that at least a part of the receiving-side plug-in connection unit (4) can move with an accessory container (10) when the accessory container (10) is electrically connected to the receiving device (3) via the receiving-side plug-in connection unit (4). A particularly reliable transmission of data signals between the control (2) of the base unit (1) and the container accessory (10) can thus be made possible. The present disclosure also relates to a corresponding accessory container.
