ABSTRACT:
A kitchen machine is provided with a base (3) and a motor housing (5) which is arranged on the base (3) and in which an electric motor (27) is accommodated. On the base (3) next to the motor housing (5), an open bowl (9) can be placed, journalled relative to the base (3). A transverse arm (17) can be coupled on the motor housing (5), which arm extends to above the bowl (9). A tool (19) can be placed in the bowl (9) and can be coupled to a transmission (25) which is arranged in the transverse arm (17) and can be driven by the electric motor (27). The bowl (9) can be driven into rotation by a pinion (21) which is also coupled to the transmission (25). The pinion (21) is displaceable along its axis of rotation relative to the transverse arm (17) and is displaced from a first into a second position through engagement with a toothed rim (23) of the bowl (9) when the transverse arm (17) is placed on the motor housing (,5). In the first position of the pinion (21), a rotary switch (69) is blocked in its zero position by a blocking mechanism (71) coupled to the pinion (21), so that the electric motor (27) cannot be switched on, whereas the rotary switch (69) is released by the blocking mechanism (71) with the pinion (21) in the second position when the transverse arm (17) is locked to the motor housing (5) by a locking mechanism (117). The kitchen machine can thus only be switched on when both the bowl (9) and the transverse arm (17) have been correctly positioned, so that the possibility of injury of a user of the kitchen machine with the rotating parts of the kitchen machine is substantially elminated.
