5. The rotary air impingement oven defined in claim 4 wherein said cooking chamber has a reflective surface to promote radiant heat transfer.

6. The rotary air impingement oven defined in claim 5 wherein said impingement disks each comprise a central hub, said hub defining a cavity to receive a drive shaft, said cavity defining a slot to receive a pin extending from said drive shaft.

7. The rotary air impingement oven defined in claim 6 wherein said slot in said second disk is generally J-shaped and said drive shaft comprises spring loaded biasing means to provide one-quarter turn locking and release of said second disk.

8. The rotary air impingement oven defined in claim 7 further comprising boiler for steaming within said oven.

9. A closed loop, rotary air impingement oven comprising:

an oven housing;

variable speed fan means for providing pressurized air;

a removable cooking chamber defined within said oven housing, said cooking chamber comprising:

a top comprising a generally circular opening for receiving a first removable, driven rotating impingement disk, said first impingement disk defining a plurality of round edged, generally circular air impingement orifices;

a bottom comprising a generally circular opening for receiving a second removable, driven rotating impingement disk, said second impingement disk defining a plurality of round edged generally circular air impingement orifices;

two opposite side walls removably mounting at least one product support surface relatively parallel to said disks; and,

a rear wall comprising an air intake to provide air flow communication between said cooking chamber and said fan means;

a front door comprising an outer panel, an inner panel and an insulated portion therebetween, said front door mounted in operative cooperation with said oven housing to selectively seal and provide access to said cooking chamber;

a hot air plenum defined between said oven housing and said cooking chamber for providing air flow communication between said fan means and said impingement disks, said plenum comprising damper means for controlling air flow within said plenum and through said orifices; and,

heater means for heating said pressurized air, said heater means disposed within said plenum and further comprising turning vanes to reduce turbulence in said pressurized air.

10. The rotary air impingement oven defined in claim 9 further comprising radiant cooking means for browning and heating the surface of said product, said radiant cooking means disposed within said plenum above said first impingement disk.

11. The rotary air impingement oven defined in claim 10 wherein said cooking chamber has a reflective surface to promote radiant heat transfer.

12. The rotary air impingement oven defined in claim 11 wherein said impingement disks each comprise a central hub, said hub defining a cavity to receive a drive shaft, said cavity defining a slot to receive a pin extending from said drive shaft, said slot in said second disk having a generally J shape and said drive shaft receiving said second disk comprising spring loaded biasing means to provide one-quarter turn locking and release of said second disk.

13. The rotary air impingement oven defined in claim 12 further comprising boiler for steaming within said oven.

14. A combination radiant heat, convection and rotary air impingement closed loop oven comprising:

an oven housing;

variable speed fan means for providing pressurized air;

a removable cooking chamber defined within said oven housing, said cooking chamber comprising:

a top comprising a generally circular opening for receiving a first removable driven rotating impingement disk, said first impingement disk comprising a plurality of round edged, generally circular air impingement orifices;

a bottom comprising a generally circular opening for receiving a second removable driven rotating impingement disk, said second impingement disk comprising a plurality of round edged, generally circular air impingement orifices;

two opposite side walls removably mounting at least one product support surface relatively parallel to said disks;

a rear wall comprising an air intake to provide air flow communication between said cooking chamber and said fan means

a from door comprising an outer panel, an inner panel and an insulated portion defined therebetween, said door in operative cooperation with said oven housing sealing and providing access to said cooking chamber;

a hot air plenum defined between said oven housing and said cooking chamber for providing air flow communication between said fan means and said impingement disks, said plenum comprising damper means for controlling air flow within said plenum and through said orifices;

heater means for heating said pressurized air within said plenum, said heater means disposed within said plenum and further comprising turning vanes to reduce turbulence in said pressurized air; and,

radiant cooking means for browning and heating the surface of said product, said radiant cooking means disposed within said plenum above said first impingement disk.

15. The rotary air impingement oven defined in claim 14 wherein said impingement disks each comprise a central hub, said hub defining a cavity to receive a drive shaft, said cavity defining a slot to receive a pin extending from said drive shaft, said slot in said second disk having a generally J shape and said drive shaft receiving said second disk comprising spring loaded biasing means to provide one-quarter turn locking and release of said second disk.
