Patent ID: 7757984

Claim:
A food processor comprising: a motor base including a housing and a motor unit mounted in said housing, said motor unit having a blade driving section disposed upwardly and outwardly of said housing; a container adapted for containing food items and having a container bottom mounted removably on said housing, said container bottom being provided with a cutting blade unit that is coupled to said blade driving section when said container bottom is mounted on said housing and that is to be driven rotatably by said motor unit; a switch unit mounted on said housing and operable so as to generate an initial control signal; a sensor unit mounted in said housing and associated operably with said motor unit, said sensor unit generating a motor rotation signal for indicating a rotary speed of said motor unit; and a control unit mounted in said housing and connected to said motor unit, said switch unit and said sensor unit, said control unit being operable in accordance with the initial control signal from said switch unit so as to activate said motor unit to operate in a sequence of an initial judgment mode and a food processing mode; said control unit determining a first target rotary speed (S 1 ) in accordance with the motor rotation signal generated by said sensor unit when said motor unit is operated in the initial judgment mode; said control unit switching operation of said motor unit from the initial judgment mode to the food processing mode upon determining the first target rotary speed (S 1 ) so as to drive rotation of said cutting blade unit to process the food items contained in said container; said control unit determining a second target rotary speed (S 2 ) in accordance with the first target rotary speed (S 1 ); said control unit activating said motor unit to rotate at the second target rotary speed (S 2 ) upon determining the second target rotary speed (S 2 ) when said motor unit is operated in the food processing mode.
