Definitions

  • the present invention generally relates to a food preparation system.
  • an embodiment of the present invention is a food processing machine including a base unit, a container with a built-in drive unit, and a mixing attachment.
  • Many food processors include a base housing that has a motor shaft extending upward and outward from the base housing.
  • a food processing container such as, for example, a bowl, is formed with an opening in the bottom and is designed to set on top of, and interlock with, the base housing.
  • the motor shaft extends into the bowl through the bottom opening of the container when the container is interlocked with the base.
  • the motor shaft supports a food processing implement, such as, for example, a blade cutter or a disk. After a lid is placed over the top of the bowl, the motor is selectively operated to rotate the shaft and the implement within the container, whereby food in the bowl is, for example, shredded, sliced, grated, and/or mixed.
  • the container, the base housing, and the lid may include interlocking mechanisms which cooperate in a complementary sense to insure that the container is firmly attached to the base housing, and the lid is secluded to the container.
  • the container is set on the base housing and is rotated to facilitate the latching of the container to the base housing.
  • the motor shaft in most food processors may only rotate in a single direction. Accordingly, the mixing attachment and its blades or cutting tools are designed to only operate in one direction and the food within the container is repeatedly subjected to the same cutting/mixing action.
  • An aspect of one embodiment of the present invention is to provide a food processor that has a base housing including a bi-directional motor and motor controls, a container which interlocks with the base housing including a two-speed, bi-directional drive shaft protruding into the container, and a mixing attachment that engages the drive shaft to process the food.
  • the base housing has a speed control dial and a pulse button.
  • the speed control dial can be rotated in a clockwise or a counterclockwise position to drive the mixing attachment in a forward or reverse direction.
  • the speed control dial can vary the mobile speed, for example, between indices 1 through 5 (slow to fast) to control the motor speed.
  • the pulse button temporarily accelerates the motor to the highest speed when depressed.
  • a container includes a drive shaft that protrudes into the container and has two independently rotating sleeves, a primary and secondary sleeve. The primary and secondary sleeve have a concentric vertical axis and rotate simultaneously at two separate speeds.
  • the primary sleeve rotates approximately eight to twelve times faster than the secondary sleeve.
  • Yet another aspect of the present invention is to provide mixing attachments that perform one function in a first direction, and a second , different function when operating in an opposite direction.
  • a chopping attachment performs one function, such as, a mixing function, when rotating in a clockwise direction, and performs a second, different function when rotating in a counterclockwise direction.
  • the two functions can be accomplished without having to flip the attachment upside down or modifying the attachment in any form.
  • One embodiment of a mixing attachment has a support column adapted to engage the drive shaft protruding into the container, a spiral deflection element along the outer surface of the support column, and a domed-shaped cap having dimples attached to the top of the support column.
  • This embodiment may also include a blade located between the pitch of the spiral deflection element.
  • Another embodiment of a mixing attachment has includes a cylindrical column with a spiral protrusion along the outer surface of the column and a paddle located at the base of the column.
  • this mixing attachment rotates in a clockwise direction, the spiral protrusion will create a downward screwing action upon the food such that the food is forced onto the paddle.
  • this attachment rotates in a counterclockwise direction, the spiral protrusion creates a lifting and aerating action upon the food being processed.
  • Another aspect of the present invention includes a lid that prevents liquid from exiting the container and provides additional lateral support for the mixing attachment while operating.
  • An embodiment of the lid has a coupling mechanism that engages the mixing attachment when the lid is placed on top of the container. Accordingly, the mixing attachment is secured on both ends.
  • Another embodiment of the lid includes a gasket that presses against the wall of the container to form a liquid tight seal to prevent liquid from traveling up the wall of the container and exiting the container.
  • Still another aspect of the present invention allows only certain attachments to operate with specific containers and/or lids.
  • the container allow the food processor to operate without a lid.
  • a user could access the mixing attachment while the food processor is operating.
  • Only non-cutting mixing attachments may be used in such an environment.
  • a cutting mixing attachment cannot engage the drive shaft associated with this container because the shape of the drive shaft and the cavity of mixing attachment are not compatible.
  • Yet another aspect of the present invention allows a user to assist in the mixing of ingredients while the food processor is operating.
  • the food processor can operate without a lid when certain non- cutting mixing attachments are operating. Without a lid on the container, a user may test the food mixture while the food processor is operating or off.

While the food processor 100 is running, a user may press the pulse button 105 to accelerate the mixing attachment to the highest speed. The pulse button 105 may be held down for as long as the highest speed is needed. Upon releasing the pulse button 105, the mixing attachment will return to its prior operating speed (e.g., the speed set by the control dial 103).
