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.

Claims (23)

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.
