ABSTRACT:
A household appliance for squeezing, comminuting or otherwise treating fruits and vegetables comprises a motor housing with a base having a lateral extensions from which a drive shaft extends upward. A cylindrical treatment vessel fits onto that extension with a hub which surrounds the drive shaft and accommodates a tubular stub shaft of an implement to be driven, the vessel having a cover which is attachable thereto through a bayonet coupling and carries a peripheral detent which must enter a slot of the motor housing and be engaged by a retractable latch to trip a microswitch enabling the motor to operate. One implement connectable with the drive shaft comprises a centrifugal grater with an annular screen and an abrasive bottom onto which produce to be comminuted can be pressed from above by a pusher passing through a guide tube of the cover; the pusher has a hollow stem closed at its lower end and cut away laterally to form an aperture with lateral edges closely adjoining the inner screen surface of the rotating grater, the edge downstream in the direction of rotation scraping off adhering fragments such as peels or fibers which can be removed during operation by withdrawing the plunger.
