Abstract: A fruit or vegetable juicer comprises a housing enclosing a motor group having an output shaft which projects into a basin secured to the housing. The output shaft drives a working tool disposed in a bowl in rotation. The bowl is movably mounted within the basin and is covered by a cover having a chute for the introduction of foodstuff, and a locking/unlocking device ensures maintenance of the bowl and the basin when the cover is in a locked condition. The bowl and the cover also comprise mutual hooking elements which permit the extraction from the basin of an assembly comprised of the bowl, the working tool and the cover, when the cover is in an unlocked condition.
