Abstract

A cooking device, comprises a base; a fulcrum mounted on the base; a support for carrying a pan, the support being mounted on the fulcrum and including first and second portions extending respectively from each side of the fulcrum a substantial distance; device for mounting the pan on the first portion; and an actuator operably associated with the second portion for periodically accelerating and decelerating rapidly the first portion about the fulcrum between first and second positions, thereby causing the pan to move upwardly and downwardly with the first portion and propel food placed therein into the air upon rapid upward deceleration and downward acceleration of the first portion and causing the food to be turned for uniform heating of different portions of the food.

Claims

1. A cooking device, comprising:

a) a base;

b) a fulcrum mounted on said base;

c) support means for carrying a pan;

d) said support means being mounted on said fulcrum and including first and second portions extending respectively from each side of said fulcrum a substantial distance;

e) means for mounting the pan on said first portion of said support means and on one side of said fulcrum; and

f) actuating means operably associated with said second portion of said support means and on the other side of said fulcrum for periodically accelerating and decelerating rapidly said first portion about said fulcrum between first and second positions, thereby causing the pan to move upwardly and downwardly with said first portion and propel food placed therein into the air upon rapid upward deceleration and downward acceleration of said first portion and causing the food to be turned for uniform heating of different portions of the food.

2. A cooking device as in claim 1, wherein:

a) said first portion is substantially longer than said second portion, whereby a small movement of said second portion is magnified into a large movement in said first portion.

3. A cooking device as in claim 1, wherein:

a) said actuating means includes a solenoid.

4. A cooking device as in claim 1, wherein:

b) said second portion includes a lost motion slot.

5. A cooking device as in claim 4, wherein:

a) said actuating means includes a solenoid operably associated with said lost motion slot.

6. A cooking device as in claim 5, wherein:

a) said solenoid includes a plunger disposed therein and moveable between third and fourth positions and a linkage operably associated with said plunger;

b) said linkage is operably associated with said lost motion slot;

c) whereby when said plunger moves between said third and fourth positions, said linkage causes said first portion to oscillate between said first and second positions.

7. A cooking device as in claim 1, wherein:

a) said actuating means includes a solenoid having a plunger; and

b) means for lubricating said plunger.

8. A cooking device as in claim 7, and further comprising:

a) means for cooling said solenoid during operation.

9. A cooking device as in claim 8, wherein:

a) said cooling means includes a liquid jacket disposed around said solenoid; and

b) means for circulating coolant liquid through said jacket.

10. A cooking device as in claim 8, wherein:

a) said lubricating means includes a pan disposed below said plunger; and

b) said pan includes a chamber communicating with said plunger.

11. A cooking device as in claim 10, wherein:

a) said circulating means includes an inlet and an outlet;

b) said inlet is operably connected to a lower portion of said jacket;

c) said outlet is operably connected to an upper portion of said jacket; and

d) said outlet includes a coil portion disposed within said pan chamber.

12. A cooking device as in claim 1, and further comprising:

a) a nozzle disposed over the pan.

13. A cooking device as in claim 12, wherein:

a) said nozzle includes inner and outer tubular members;

b) said inner member is disposed within said outer member for defining an annular passageway therebetween; and

c) said inner member includes a plurality of inlets and an outlet.

14. A cooking device as in claim 12, wherein:

a) said outer member includes an inlet at its upper end and an annular opening at its lower end; and

b) said annular opening communicates with said annular passageway.

15. A cooking device as in claim 14, wherein:

a) said inner member includes a chamber; and

b) said inner member outlet has an opening substantially smaller than said chamber.

16. A cooking device as in claim 12, and further comprising:

a) burner means for providing heat to the pan.

17. A cooking device as in claim 16, and further comprising:

a) means for operating said solenoid, said nozzle, and said burner means in a preselected manner.

18. A cooking device as in claim 17, wherein:

a) said operating means includes a plurality of solenoid valves;

b) each of said solenoid valves is operably associated with each of said plurality of inlets and said burner means.

19. A cooking device as in claim 18, wherein:

a) said operating means includes timer means for operating each of said solenoid valves and said solenoid in a preselected sequence.

20. A cooking device, comprising:

a) a base;

b) support means operably associated with said base for carrying a pan;

c) pivot means operably associated with said support means for permitting said support means to oscillate from the horizontal between first and second positions;

d) solenoid drive means operably associated with said support means for periodically accelerating and decelerating rapidly said support means about said pivot between said first and second positions, thereby causing the pan to move upwardly and downwardly with said support means and propel food placed therein into the air upon rapid upward deceleration and downward acceleration of said support means and causing the food to be turned for uniform heating of different portions of the food; and

e) means for automatically controlling the operation of said solenoid drive means in a preselected sequence.

21. A cooking device as in claim 20, wherein:

a) said controlling means includes timer means operably associated with said solenoid drive means for periodically operating said solenoid.

22. A cooking device as in claim 21, wherein:

a) said timer means includes an adjustable timer.

23. A food cooking device, comprising:

a) a base;

b) support means operably associated with said base for carrying a pan;

c) pivot means operably associated with said support means for permitting said support means to oscillate from the horizontal between first and second positions; and

d) solenoid drive means operably associated with said support means for periodically accelerating and decelerating rapidly said support means about said pivot means between said first and second positions, thereby causing the pan to move upwardly and downwardly with said support means and propel food placed therein into the air upon rapid upward deceleration and downward acceleration of said support means and causing the food to be turned for uniform heating of different portions of the food.
