A safety device for a food processor having a bowl closed by a cover and fed through a chute for introducing products into the working bowl, has a control switch responsive to the position of a pusher guide carrying a pusher. The pusher is slidably mounted for translation in the pusher-guide. The pusher-guide is pivotally mounted to cover over the open end of the chute, and a set of rods connect the pusher-guide to the switch operating safety rod extending along the bowl. The device prevents access of the user's hand to the cutting area, even for a large chute, by blocking the chute when the motor is enabled.

1. A safety device for a food processor with a rotating tool driven by an electrical motor unit on which is mounted a bowl that is closed by a cover, the device comprising: a chute for introducing food, a safety rod bearing on a switch arranged in the circuit of the motor unit, a pusher guided for translation in the chute by a pusher-guide, wherein the pusher-guide is articulated to place the pusher at a top of the chute and is mechanically connected to push the safety rod, the mechanism causing the motor to stop upon a small angular clearance of the pusher-guide. 2. The safety device according to claim 1, wherein the chute has a generally cylindrical shape, and the pusher defines a surface substantially equal to a cross section of the chute. 3. The safety device according to claim 1, wherein the pusher-guide drives a connecting rod by means of an articulation, which connecting rod forces, by means of the articulation, rotation of a crankshaft around a pin that is fixed with respect to the cover, said crankshaft driving in turn, by means of the articulation, a rod which acts on the switch, the switch being located in the motor unit and operated through the rod, the rod being guided for translation relative to a wall of the bowl, the rod being upwardly returned by a spring. 4. The safety device according to claim 1, wherein upon closing the pusher-guide on the chute, the motor is enabled provided that the pusher-guide is within a predetermined inclination angle relative to a closed position, and wherein the predetermined inclination angle permits the products to protrude beyond an upper level of the chute. 5. The safety device according to claim 1, wherein the pusher-guide is mounted by mechanics that exert a resisting force to displacement of the pusher from a closed position on the chute, whereby the pusher can slide in the pusher-guide without causing said pusher-guide to pivot. 6. The safety device according to claim 1, wherein the pusher-guide is articulated on a pin, and contact of the rod on the switch is established when the pusher-guide forms an angle of about 10° relative to a closed position and said contact is interrupted when the pusher-guide forms an angle of about 11°.
