Abstract: A stirrer for inserting into a bottom opening of a vessel bottom of a stirring vessel of an electric motor operated kitchen appliance has a plurality of positioning protrusions embodied on its circumferential surface one behind the other in the circumferential direction. A plurality of first positioning protrusions of the circumferential surface protrude with a first radial length difference beyond a smallest radius of the circumferential surface. At least one second positioning protrusion protrudes with a second radial length difference beyond the smallest radius of the circumferential surface, which second radial length difference is smaller than the first radial length difference.

Abstract: A mixing vessel for an electric motor-operated food processor, with a vessel floor, an agitator extending through the vessel floor into the mixing vessel, and a foot part that can be externally connected with the vessel floor, which is designed for fixing the agitator to the vessel floor. In order to prevent a user from filling the mixing vessel without the agitator properly assembled in the food processor, it is proposed that the vessel floor or foot part have a blocking element that can be exposed to the spring force of a spring element, and can be shifted against the spring force by means of a corresponding contact element of the foot part or vessel floor from a blocking position that prevents a fixation of the agitator into a release position that enables a fixation.
