Abstract

An electric cooking appliance that has a removable cooking pot, positive locking between the cooking pot and a base configured for heating food in the pot, with the heating base also being configured for tilting the cooking pot up to an approximate forty-five degree angle from its original position. The appliance also includes a collar configured for upward positioning beyond the top edge of the cooking pot and a stirring motor arm with at least one connected stirring blade that extends into the cooking pot when the pot is in its usable position and locked onto the base. The collar tapers inwardly over the lateral edges of the stirring blade to reduce splashing and spilling in both level and tilted orientations. Stirring speed and the amount of tilt are adjustable. Further, applications can include, but are not limited to, the cooking of stir fry dishes, fudge, soups, vegetables, and stews.

Claims

1. An electrical cooking appliance comprising:

a cooking pot having a top edge and interior side surfaces;

a base configured for removable receipt of said cooking pot in a non-tilted orientation, said base also configured for repositioning said cooking pot into at least one tilted orientation, and said base further configured for providing a temporary but user-releasable positive lock between said cooking pot and said base so that said cooking pot remains fixed to said base when said cooking pot is in said at least one tilted orientation, and said base further having the capability of providing heat sufficient for cooking food placed into said cooking pot when said cooking pot is positively locked onto said base;

a drive shaft;

a stirring motor arm with a distal end and a proximal end, said proximal end pivotally connected to said base so that said stirring motor arm is movable between a lowered position where said distal end is close to said base and a raised position, said distal end also configured for receipt and rotation of said drive shaft; and

at least one stirring blade configured for being rotated by said drive shaft, said stirring blade also having opposed ends configured so that at least one of said opposed ends reaches food close to said interior side surfaces of said cooking pot when said at least one stirring blade is connected to said stirring motor arm, said cooking pot is locked onto said base, and said at least one stirring blade extends into said cooking pot.

2. The cooking appliance of claim 1 wherein said at least one stirring blade has one end at least one end configured to reach food close to said interior side surfaces of said cooking pot and a second end configured for positioning more centrally within said cooking pot.

3. The cooking appliance of claim 1 wherein said tilted orientation is a maximum of approximately forty-five degrees from said non-tilted orientation.

4. The cooking appliance of claim 1 further comprising a splash and spill reducing collar configured for association with said top edge of said cooking pot, said collar extending upwardly beyond said top edge, and said collar further having an inwardly-tapering upper edge above stirring blade.

5. The cooking appliance of claim 1 wherein said cooking pot, said at least one stirring blade, and said collar are made from dishwasher safe materials.

6. The cooking appliance of claim 1 further comprising microprocessor control of stirring blade rotation, heat production of said base, and tilting of said base.

7. The cooking appliance of claim 6 wherein said rotation and said heat production are selected from a group consisting of rotation having a delayed start, heat production having a delayed start, rotation and heat production having a delayed start, rotation ceasing at a pre-determined time after food cooking begins, heat production ceasing at a pre-determined time after food cooking begins, rotation and heat production ceasing at a pre-determined time after food cooking begins, rotation and heat production commencing at the same time, rotation and heat production ceasing at the same time, and rotation and heat production operating independently from one another.

8. The cooking appliance of claim 1 further wherein rotation of said stirring blade is selected from a group consisting of comprising an additional cooking pot having a diameter dimension different from that of said cooking pot, and wherein said base is configured to accommodate and securely lock into place one at a time said cooking pot and said additional cooking pot.

9. The cooking appliance of claim 1 wherein tilting of said base is accomplished via members selected from a group consisting of internally-housed tilt mechanisms and externally-housed tilt mechanisms.

10. The cooking appliance of claim 1 wherein said base is configured for repositioning said cooking pot into multiple tilted orientations.

11. The cooking appliance of claim 1 wherein rotation of said stirring blade is selected from a group consisting of adjustable rotation, rotation wherein intermittent stirring occurs and rotation wherein increased frequency of stirring occurs at the end of food preparation when the burning and/or sticking of food being cooked is most likely to occur.

12. The cooking appliance of claim 1 wherein said cooking pot has at least one insulated handle.

13. The cooking appliance of claim 1 wherein said base has a front portion with a widened blunt area that is configured to provide stability when said base is in a tilted orientation.

14. An electrical cooking appliance comprising:

a cooking pot having a top edge and interior side surfaces;

a splash and spill reducing collar configured for association with said top edge of said cooking pot, said collar extending upwardly beyond said top edge, and said collar further having an inwardly-tapering upper edge;

a base configured for removable receipt of said cooking pot in a non-tilted orientation, said base also configured for repositioning said cooking pot into at least one tilted orientation, and said base further configured for providing a temporary but user-releasable positive lock between said cooking pot and said base so that said cooking pot remains fixed to said base when said cooking pot is in said at least one tilted orientation, and said base further having the capability of providing heat sufficient for cooking food placed into said cooking pot when said cooking pot is positively locked onto said base;

a drive shaft;

a stirring motor arm with a distal end and a proximal end, said proximal end pivotally connected to said base so that said stirring motor arm is movable between a lowered position where said distal end is close to said base and a raised position, said distal end also configured for receipt and rotation of said drive shaft; and

a stirring blade configured for connection to said drive shaft and being rotated by said drive shaft, said stirring blade also having opposed ends configured so that the first of said opposed ends reaches food close to said interior side surfaces of said cooking pot and the second of said opposed ends is configured for positioning more centrally within said cooking pot while said stirring blade is connected to said stirring motor arm, said cooking pot is locked onto said base, and said stirring blade extends into said cooking pot, and further so that said an inwardly-tapering upper edge of said collar extends over said opposed ends of said stirring blade to reduce food splashing and spilling particularly in said at least one tilted orientation.

15. The cooking appliance of claim 14 wherein said tilted orientation is a maximum of approximately forty-five degrees from said non-tilted orientation.

16. The cooking appliance of claim 14 further comprising microprocessor control of stirring blade rotation, heat production of said base, and tilting of said base.

17. The cooking appliance of claim 16 wherein said rotation and said heat production are selected from a group consisting of rotation having a delayed start, heat production having a delayed start, rotation and heat production having a delayed start, rotation ceasing at a pre-determined time after food cooking begins, heat production ceasing at a pre-determined time after food cooking begins, rotation and heat production ceasing at a pre-determined time after food cooking begins, rotation and heat production commencing at the same time, rotation and heat production ceasing at the same time, and rotation and heat production operating independently from one another.

18. The cooking appliance of claim 14 further wherein rotation of said stirring blade is selected from a group consisting of comprising an additional cooking pot having a diameter dimension different from that of said cooking pot, and wherein said base is configured to accommodate and securely lock into place one at a time said cooking pot and said additional cooking pot.
