ABSTRACT:
A kitchen machine with a housing (1) and a bowl (9) which can be placed on the housing (1) and can be closed with a lid (33). A rotary tool (27) can be placed in the bowl (9) and can be driven by means of an electric motor (21) arranged in the housing (1). The kitchen machine is provided with a locking device (63) which locks the lid (33) during rotation of the tool (27) in order to prevent that a user of the kitchen machine can injure himself with the rotating tool (27).
The locking device comprises a centrifugal member (65, 111) which cooperates with a safety member (105). The use of the centrifugal member (65, 111) achieves that the lid (33) is not released by the safety member (105) after switching-off of the electric motor (21) until the moment the tool (27) has come substantially to a standstill. It is prevented in this way that the user can injure himself with the tool (27) still running out under the influence of its mass inertia after switching-off of the electric motor (21).
