Food processor

摘要

The invention relates to an improvement in food processors of the kind that include a stand (1), a motor (2), a drive shaft (3), and a knob (4) or like device for operating the motor (2), wherein the processor further comprises an S-blade device (5) that includes a container (6) for the raw material or materials to be prepared, a container lid (7) and one or more knives (8, 9) that are driven by said drive shaft and located at the bottom of the container, and wherein the processor also comprises a vegetable cutting means that includes a cutting disc (10) which is intended to be fastened at the top of said drive shaft, and feed means (11) mounted above the cutting disc and used to feed raw materials to be cut. The invention is characterized by two mutually spaced sensors (14, 15) in the upper part (13) of the stand (1) and is further characterised in that one of the sensors or both of said sensors is/are adapted to coact with sensor-parts (16, 17, 18) placed respectively in said lid (7) and said feed means (11); in that either the lid or the feed means is provided with a sensor-part adapted to co-act with solely one (14) of the sensors in the stand (1) while the other of said lid or said feed means is provided with two mutually spaced sensor-parts adapted to co-act with both of the sensors (14, 15) in the stand; and in that the stand sensors (14, 15) are connected to a control circuit (21) which functions to sense which of the sensors is active and to cause the motor regulating circuit (23) to activate the motor in two different speed ranges, depending on whether only one or both of said sensors (14, 15) is/are active.
