Abstract

An enlarged food pusher with clean-out windows is provided in a feedtube protector assembly utilized with a food processor. The feedtube protector includes an outer sleeve nestable around the exterior of an expanded feedtube which forms a first passageway for feeding food items through the cover into the bowl. A telescoping oval-shaped food pusher on the outer sleeve moves longitudinally in the expanded feedtube for pushing food items onto the rotary tool. A second passageway is provided by a tubular member extending through the food pusher which is adapted to receive a removable food pusher normally retained within the second passageway when the larger food pusher is being used. The oval-shaped food pusher has an enclosed bottom end extending from its periphery inwardly to the second food passageway. A pair of crescent-shaped cavities having four cusp regions defined between the oval-shaped pusher and the tubular member are open and may accumulate food which may be difficult to remove. To alleviate this problem L-shaped clean-out and drain ports are provided in the side wall of the captured food pusher adjacent the bottom thereof. One leg of each of these L-shaped ports communicate with a respective cusp region and the other leg is wider and extends vertically above the first leg thereby providing a means for cleaning the cavities within the interior of the oval-shaped food pusher.

In a food processor of the type including a housing containing an electric motor drive and control means for rendering said motor drive inoperative unless said control means is actuated, a bowl mountable on said housing for enclosing a rotatable tool within said bowl drivable by tool drive means when said motor drive is rendered operative by actuation of said control means, a removable cover adapted to be positioned on said bowl with an expanded feedtube mounted on said cover forming a first food passageway for feeding food items through said cover into said bowl toward the rotating tool, a feedtube protector having an outer sleeve nestable in a predetermined position around the exterior of said feedtube, a captured food pusher of oblong cross-sectional configuration being captured in telescoping relationship with respect to said outer sleeve for enabling said captured food pusher to move longitudinally within said outer sleeve, said captured food pusher being in alignment with the interior of said outer sleeve for causing said captured food pusher to become aligned with said first food passageway and plungable therein only when said outer sleeve is nested around said feedtube, said captured food pusher having a bottom surface enclosing one end of said captured food pusher which end comes into contact with the food items being fed into said bowl, a second food passageway formed by a circular-shaped tubular member extending through said captured food pusher defining crescent-shaped cavities having cusp regions within said captured food pusher, an improved feedtube protector structure comprising:

at least one clean-out port in a side wall of said captured food pusher communicating with said cusp region of each crescent-shaped cavity adjacent the bottom of said captured food pusher, and
at least one drain port extending horizontally around the periphery of said bottom of said captured food pusher communicating with said cusp region of each of said crescent-shaped cavities,
said clean-out port and said drain port being joined with said clean-out port extending vertically above said drain port thereby providing a means for cleaning the interior of said captured food pusher.
