Description

FIELD OF THE INVENTION

The present invention relates to food processors and, more particularly, to a food processor having a feed tube assembly that secures food during processing.

BACKGROUND OF THE INVENTION

Food processing devices providing a number of different types of food preparations, such as mixing, grinding, chopping, slicing, grating, shredding, or other processing operations, are well known. Existing food processing devices typically include a base housing an electric motor, a drive shaft driven by the motor, a bowl receivable on the base and a lid or cover having a feed tube releasably mounted to the bowl. A rotatably driven blade is mounted to the drive shaft to process one or more food items inside the bowl.

While existing food processing devices are generally suitable for what is regarded as ordinary performance, there is room for improvement in terms of ease of use and expanded functionality.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a food processor having a feed tube.

It is another object of the present invention to provide a food processor having a feed tube that secures food items within the feed tube.

These and other objects are achieved by the present invention.

According to an embodiment of the present invention, a feed tube assembly for a food processor is provided. The feed tube assembly includes a first member having a channel therethrough configured to be slidably received in a feed tube of a food processor, and a second member slidably received in the channel of the first member. The first member also includes a flat spring that extends into the channel to secure food items within the channel.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be better understood from reading the following description of non-limiting embodiments, with reference to the attached drawings, wherein below:

FIG. 1 is a perspective view of a food processor according to an embodiment of the present invention.

FIG. 2 is a perspective view of a feed tube assembly for a food processor according to an embodiment of the present invention.

FIG. 3 is a enlarged, cross-sectional view of the feed tube assembly of FIG. 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a food processor 10 according to the present invention is shown. The food processor 10 includes a base 12, a work bowl or receptacle 14 received on the base 12, and a lid 16 configured to be selectively removable from the work bowl 14. Base 12 includes a motor or other rotary drive mechanism (not shown) connected to a rotatable output shaft 18 for rotatably driving a blade interior to the work bowl 14 and may include controls (not shown) for varying settings of the motor.

As further shown therein, work bowl 14 is generally cylindrical or frusto-conical in shape and has a handle 20 and a pour spout (not shown). The lid 16 defines a substantially circular body sized and is dimensioned to cover work bowl 14. The lid 16 also includes a feed tube opening (not shown). The feed tube opening may be generally oval in shape, although other shapes and dimensions are envisioned without departing from the broader aspects of the present invention.

As best shown in FIG. 1, the lid 16 may also include a feed tube 22 defining a substantially annular body having a substantially oval cross-section extending upwards from the lid 16 and in communication with the feed tube opening. As is well known in the art, the feed tube 22 provides a chute through which a user may load food items to be processed into the work bowl 14.

Turning now to FIG. 2, a feed tube assembly 24 is slidably received in the feed tube 22. As shown therein, the feed tube assembly 24 includes a first member 26, and a second member 28 slidably received by the first member 26. In particular, the first member 26 defines a generally annular body having sidewalls and a closed top and bottom. The first member 26 is sized and shaped so as to be closely and slidably received by the internal walls of feed tube 22. The first member 26 also includes a channel 30 for slidably receiving the second member 28. The first member 26 and second member 28 may be referred to as a large food pusher and a small food pusher. As is known in the art, the food pushers 26, 28 are utilized by a user to urge food items in the feed tube 22 into the work bowl 14 for processing by the blade assembly (not shown). Importantly, the large food pusher 26 may be utilized for large food items and the small food pusher 28 may be utilized for smaller food items.

With reference to FIGS. 2 and 3, the first member/food pusher 26 includes a spring, such as flat spring 32, that extends from the first member 26 into the channel 30. As best shown in FIG. 3, the top of the spring 30 is retained against the rear wall 34 of the channel 30 and the bottom of the spring is spaced from the rear wall 34. In particular, the spring 32 is biased to a position such that it is oriented at an angle with respect to the rear wall 34 of the channel 30 and such that the bottom of the spring 32 protrudes into the channel 30. In the preferred embodiment, the spring 32 is formed from stainless steel, although other materials may be utilized without departing from the broader aspects of the present invention.

Importantly, the spring 32 functions to help secure and retain food items within the channel 30 during processing. In particular, the spring 32 prevents food items from simply falling into the work bowl 14 too fast. In operation, a user loads food items into the channel 30, where the food items are retained by the spring 32, and utilizes the small food pusher 28 to urge the food items through the channel 30 and into the work bowl 14. Upon exerting downward pressure on the food items, the spring 32 is pushed against the rear wall 34 of the channel 30, against the bias of the spring, such that the food items in the channel 30 are permitted to now pass the spring 32.

Although this invention has been shown and described with respect to the detailed embodiments thereof, it will be understood by those of skill in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed in the above detailed description, but that the invention will include all embodiments falling within the scope of this disclosure.
