A food processor includes a base and a bowl with a removable lid. Food items are advanced into the bowl through a feed tube formed in the lid where they are cut by a cutting assembly driven by a motor. The lid includes a user-operated button operable to control the motor.
Claims12
A food processing device comprising
- a base having:
- a motor positioned therein,
- a first switch positioned in the base, the first switch being operable to energize the motor at a first cutting speed when a first button of a pair of user-operated buttons is depressed, and
- a second switch positioned in the base, the second switch being operable to energize the motor at a second cutting speed when a second button of the pair of user-operated buttons is depressed,
- a removable bowl coupled to the base, the removable bowl having:
- a processing chamber defined therein,
- a first arm positioned between the first button and the first switch when a lid is coupled to the bowl, the first arm being moveable upwardly and downwardly relative to the base by the first button to operate the first switch, and
- a second arm positioned between the second button and the second switch when the lid is coupled to the bowl, the second arm being upwardly and downwardly moveable relative to the base by the second button to operate the second switch,
- a cutting assembly positioned in the processing chamber and driven by the motor to cut food items placed in the processing chamber,
- the lid configured to be coupled to the bowl, the lid including a first section having a feed tube that opens into the bowl and the pair of user-operated buttons operable to activate the motor, and
- a locking mechanism configured to prevent activation of the motor when the lid is decoupled from the bowl wherein the locking mechanism comprises a plate moveably coupled to the bowl, the plate being positionable between (i) a first position in which the plate engages the first arm and the second arm such that movement of the first arm and the second arm relative to the base is prevented, and (ii) a second position in which the plate is disengaged from the first arm and the second arm such that movement of the first arm and the second arm relative to the base is permitted.

A food processing device comprising
- a base having a motor positioned therein,
- a removable bowl coupled to the base, the removable bowl including a linkage assembly that is upwardly and downwardly moveable relative to the base to operate the motor,
- a cutting assembly positioned in the bowl and driven by the motor to cut food items placed in the bowl,
- a lid configured to be coupled to the bowl, the lid including a feed tube that opens into the bowl and a user-operated button configured to move the linkage assembly relative to the base to operate the motor, and
- a locking mechanism configured to prevent movement of the linkage assembly when the lid is decoupled from the bowl wherein the locking mechanism comprises a plate positionable between (i) a first position in which the plate engages the linkage assembly such that movement of the linkage assembly relative to the base is prevented, and (ii) a second position in which the plate is disengaged from the linkage assembly such that movement of the linkage assembly relative to the base is permitted.
