In a kitchen machine, an electric motor (5) driving a rotating tool (4) is reversible in its direction of rotation. By means of a gear mechanism (6), two driven wheels (13, 15) arranged rotatably on a drive sleeve (3) are continuously driven at different rotational speed. Wrap springs (18, 19) connect, depending on the direction of rotation, one or other of the driven wheels (13, 15) to a drive sleeve (3) in which the rotating tool (4) is seated. <IMAGE>
