DETAILED DESCRIPTION OF THE INVENTION

[0014] The following are more detailed descriptions of various related concepts related to, and embodiments of, methods and apparatus according to the present disclosure. It should be appreciated that various aspects of the subject matter introduced above and discussed in greater detail below may be implemented in any of numerous ways, as the subject matter is not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

[0015] The various embodiments of the invention are directed to an oscillating food processor assembly having an upright or tower configuration with a blade support member and a blade member engaged with a top portion of the tower. In one particular embodiment, the food processing assembly is configured to process food received in an inlet chute using a blade assembly located on the blade member that is operated in an oscillating mode.

[0016] Referring now to the figures, FIG. 1 a right side view of an improved food processing assembly 100 including a food processing tower 110 having a base 112, an upright member 113, an integrated motor 114 located in tower 110 with a motor control switch 111 for actuating the motor in an oscillating mode, a top portion 115 that supports a circular blade support member 120 and a circular blade member 130 that is engaged with a drive shaft assembly in tower 110. In this example embodiment, circular blade support member 120 includes an inlet chute 122 on the surface of member 120 and an outlet chute 134 protruding underneath therefrom and directing cut or processed food into a bowl 140. In this example embodiment, tower portion 110 includes motor 114 and a drive shaft assembly (not shown; located in top portion 115) configured to oscillate a drive shaft (not shown) axially about a longitudinal axis of the drive shaft in an oscillating mode (see both bidirectional arrows in FIG. 2).

[0017] Further, in this example embodiment, a mode cutting selector switch 116 is located on the top of tower 110 to select the cutting mode of blade member 130. In one example embodiment, blade member 130 is supported by blade support member 120 and includes at least one blade assembly 131 disposed thereon. Blade member 130 is removably engaged with the drive assembly in top portion 115 of the tower such that the blade member 130 and the motor drive shaft assembly process food received at inlet chute 122 as blade member 130 is being oscillated axially by motor 114 and directing processed food through outlet chute 124. In this example embodiment, blade member 130 oscillates independent of blade support member 120. Referring again to FIG. 1, blade support member 120 and blade member 130 are substantially concave (similar to a cone) in configuration and blade member 130 is in a concentric relationship with and located within blade support member 120. In this example embodiment, blade member 130 has a center portion 132 by which the blade member is supported by the drive shaft at an angle (open end angled away from the tower) and is supported such that blade assembly 131 is aligned under inlet chute 122 of blade support member 120 and aligned with outlet chute 124.

[0018] In this example embodiment, top portion 115 of the tower includes food processing (or mode cutting) selector switch 116 for selecting, for instance, a blade assembly 131 on blade member 130, selector switch 116 being configured to rotate blade member 130 axially to a selected blade assembly to be aligned under inlet chute 122. Upon actuation, the motor and drive assembly oscillate circular blade member 130 (as shown) axially under inlet chute 122 such that the axial movement of the circular blade member (see arrow in center portion of blade member 130 in FIG. 2) is limited to within a portion of the blade surface, which in this example is a quadrant portion of the blade member. In this example embodiment, the oscillating mode can be continuous or in a pulse mode, depending on the user. In a related embodiment, in food processing assembly 100, motor 114 and the drive shaft assembly are configured to rotate the blade member in a continuous (or pulse) rotating mode. In this example embodiment, the motor is preferably a conventional electric motor and is operatively engaged with and oscillates the outwardly extending drive shaft protruding from the base or from the top portion of tower 110. In this example embodiment, blade support member 120 and chutes 122 and 124 are made of transparent or translucent plastic but can also be made of glass, such as Pyrex brand of glass, or ceramic, molded polymeric or PTFE material and may be constructed of nearly any rigid, structural material that is able to take on the general shape of the blade support member and chutes.

[0019] Referring now to FIG. 2 illustrates one example embodiment of a top view of circular blade member 120 of FIG. 1 divided into four equally sized quadrants A, B, C and D, with each quadrant having thereon at least one blade assembly (133, 134, 136 and 138) in accordance with the invention. In one example embodiment, blade member 130 is comprised of at least four quadrants, wherein each quadrant includes at least one of a slicing blade assembly 133, a shredding (or grating) blade assembly 134, a dicing blade assembly 136 and a Julienne blade assembly 138. In one specific example, in quadrant A, a longitudinal portion of slicing blade assembly 133 and an opening extend radially from about center portion 132 of blade member 130 towards an edge of the blade member. In this example embodiment, when blade member 130 is mounted in a food processing apparatus, such as in FIG. 1 or in a standard food processor with a bowl or jar, a cover lid and motor in the base configuration, it is rotatable axially about a longitudinal axis that is through center portion 132 so as to be aligned under inlet chute 122 of blade support member 120. In this example, each quadrant of blade member 130 is configured to be aligned under the inlet chute of the blade support member 120 depending on the type of cut or food processing that the user wants. The bidirectional arrow in center portion 132 and the bidirectional arrow on the perimeter or outside of blade member 130 indicate that blade member 130 is configured for oscillating or back and forth movement. In this example embodiment, the oscillating movement is limited to movement within each quadrant so as to achieve the desired processing of food items.

[0020] In a related embodiment, blade member 130 is configurable to oscillate between each of two sections or halves, each with a particular blade assembly, such that blade member 130 is oscillated within each half or section. In yet another example embodiment, blade member is configured to divide the cutting surface into 3 equidistant portions. In yet another related embodiment, blade member 130 and the motor assembly is configurable to increase the number of portions and blade assemblies formed on the surface of the blade member and are not just limited to 2 halves or 4 quadrants.

[0021] In a related example embodiment, a food processing accessory or blade member 130 is provided comprised of a substantially disc-shaped blade member having a center portion 132 and at least two blade assemblies disposed on a surface of the blade member. In this example embodiment the blade assemblies extends from about the center portion towards an edge of the disc-shaped blade member. In this example embodiment, the surface of the blade member is divided into two equidistant sections or halves and each of blade assemblies is located within each section or half. In yet another related embodiment, the surface of blade member is subdivided into 3 equidistant sections, with each section having a different blade assembly. In a related embodiment, the blade assemblies are selected from the group consisting of a slicing assembly, a shredding assembly, a grating assembly and a dicing assembly.

[0022] In this example embodiment, blade support member 120, inlet chute 122 and outlet chute 124 of food cutting assembly 100 are preferably constructed of molded polymeric or PTFE material and may be constructed of nearly any rigid, structural material that is able to take on the general shape of the blade support member. Blade support member 120, in this example embodiment is secured via an interlock to the top portion of tower 112 with food processing assembly 130 being mounted onto the drive shaft located at the top portion of tower 112. Once the food processor motor 112 is turned on and set to the desired oscillating mode (in a related embodiment, the motor can be turn on a desired rotational speed so as to begin rotation of food cutting assembly 120), the user can then urge the first foodstuff or vegetable downwardly through inlet chute 122 and towards blade member 120 with blade assembly 131 preferably using a pusher to do so, so as to begin the processing of the first foodstuff.

[0023] In a related embodiment, blade member 130 is configurable for use in a standard food processing arrangement that uses a jar or bowl, a cover lid with an inlet chute and a motor with drive shaft (protruding upwards into the bowl and up from the base) located in a food processing base with the motor controls located thereon. In related embodiments, blade member 130 can be a cone shape, a disc shape or a drum shape as well. Where blade member 130 is in the shape of a drum, in a related embodiment, the blade assemblies can either be located at the top of the drum or on the side (if it is shaped as a cylinder drum) and have a side inlet chute. In this example embodiment, the drum blade member is engaged with the drive shaft at the bottom of the processor and oscillated similar to a disc blade.
