ABSTRACT:
The electric food processor has a housing in which there is disposed an electric motor with a motor shaft. The motor shaft, via a gear mechanism, drives three or more concentric output drives at different rotational speeds. The common axis of rotation of the output drives is spaced a distance from the motor shaft. Working tools are selectively coupled to the output drives and the working tools rotate in a working container which is placed on the housing. In order to expand the possible uses of the food processor, the fastest output drive rotates at a speed that is suitable for a mixing tool, and the gear mechanism has at least two sets of input gear teeth that are rotatably mounted independently of each other, so that the fastest output drive can be driven out of direct engagement with the slower output drives.
