Abstract

An apparatus and method of cleaning a food processor including providing a food processor base that includes a rotary power driver having a rotatable shaft. A bowl is mounted on the base. A food processing blade attached to the shaft within the bowl. A cleaning accessory is placed in the bowl above the food processing blade. A cleaning fluid is introduced into the bowl, and the food processing blade with the rotatable shaft agitate the cleaning fluid in conjunction with the cleaning accessory.

First claim

That which is claimed is:

1. A self-cleanable food processor, comprising:
a base that includes a rotary power driver having a rotatable shaft;
a bowl mounted on the base;
a food processing blade attached to the shaft within the bowl; and
a cleaning accessory mountable on the bowl for sliding contact relative thereto and above the food processor blade, the cleaning accessory including a generally horizontal panel and projections mounted on and protruding from a lower surface of the panel, each of the projections extending in its greatest dimension in the radial direction.

2. The food processor defined in claim 1 , wherein the cleaning accessory includes holes between the projections.

3. The food processor defined in claim 1 , wherein the projections comprise fins.

4. The food processor defined in claim 1 , wherein the projections comprise rays.

5. The food processor defined in claim 4 , wherein the rays are arced to form a multi-arm spiral pattern.

6. The food processor defined in claim 5 , wherein the spiral pattern follows a first rotative direction, the food processing blade and rotary power driver are configured to drive the food processing blade in a second rotative direction, and wherein the first rotative direction is opposite of the second rotative direction.

7. The food processor defined in claim 1 , wherein the cleaning accessory further comprises projections mounted on and protruding from an upper surface thereof.

8. The food processor defined in claim 7 , wherein the projections extend downwardly from the lower surface to a distance of between about 1 mm and 25 mm of the food processing blade.

9. The food processor defined in claim 1 , wherein the food processing blade comprises an S-blade.

10. The food processor defined in claim 1 , further comprising a food processing accessory mounted to the shaft above the cleaning accessory.

11. The food processor defined in claim 1 , wherein the cleaning accessory is configured to rotate independently of the shaft.

12. A self-cleanable food processor, comprising:
a base that includes a rotary power driver having a rotatable shaft;
a bowl mounted on the base;
a food processing blade attached to the shaft within the bowl; and
a cleaning accessory configured to clean the food processing blade and mountable on the bowl for sliding contact relative thereto and above the food processing blade, the cleaning accessory including a generally horizontal panel with a plurality of openings.

13. The cleaning accessory defined in claim 12 , wherein the cleaning accessory further comprises protrusions extending downwardly from the panel.

14. The food processor defined in claim 12 , wherein the cleaning accessory is configured to rotate independently of the shaft.

15. The food processor defined in claim 12 , wherein the food processing blade comprises an S-blade.
