Abstract:
Electrical household appliance for processing food, comprising a housing (1) enclosing an electric motor group (2) and having a region forming a base (4) whose upper surface (6) is traversed by the output shaft (8) of the motor group (2); a bowl (9) removably locked on the base (4) of the housing, closed by locking a removable cover (12), and housing a working tool (16) adapted to be driven in rotation by the shaft (8) of the motor group; and a safety device (25) comprising a switch (47) arranged in the supply circuit of the motor, a pusher (27) vertically slidably mounted in a recess (29) provided over all the height of the peripheral wall (30) of the bowl (9), whose lower end (36) is disposed in line with an opening (39) provided in the peripheral of the base (4) of the housing, when the bowl (9) is locked on the base, and whose upper end (41) is adapted to be actuated by a cam (43) carried by the cover (12), when this latter is locked in place on the bowl, such that the pusher (27) enters the opening (39) of the base, as well as a control mechanism (45) disposed in the housing (1), actuated by the pusher (27) when it is in said opening (39), and controlling the closure of the switch (47) to permit supply of the motor,characterized in that the safety device (25) moreover comprises a rigid member forming a cover (49) which is movably mounted on the upper surface (6) of the base (4) of the housing between a rest position to which it is automatically brought when the bowl (9) is not in place on the base (4) and in which it covers the opening (39) in the base, and an active position in which it is displaced under the action of an actuating member (51) carried by the bowl (9) during locking of this latter onto the base (4) and in which it uncovers the opening (39) in the base so as to permit passage of the pusher (27).
