Abstract: A machine of the whisk-mixer type having: a stand (2) equipped with a cradle (6) for holding a bowl (7) opposite a tool-support head (4); a protective screen (8) that can be moved between an active safety position in which it cooperates with the bowl to prevent access to the tool and a retracted position; and a detector (13) for detecting that the screen is present in the active position so as to allow the machine to operate, wherein the screen (8) comprises rods (10) which provide for removable attachment of the screen to an articulated lever mechanism (9) for articulating the screen to the stand of the machine, and wherein the cradle (6) and the bowl (7) prevent the screen from being removed at least while it is in the active position.
