Abstract

A cooking appliance, as provided herein, may include a cabinet, a heating element, a first false wall, a second false wall, and a spit rod. The cabinet may define a cooking chamber. The cooking chamber may extend along a lateral direction between a first chamber side and a second chamber side. The heating element may be mounted within the cabinet. The first false wall may be slidably positioned within the cooking chamber at the first chamber side. The second false wall may be slidably positioned within the cooking chamber at the second chamber side. The spit rod may define a rotation axis from a first rod end to a second rod. The first rod end may be attached to the first false wall to slide therewith. The second rod end may be attached to the second false wall to slide therewith.

First claim

What is claimed is:

1. A cooking appliance defining a mutually-orthogonal vertical direction, lateral direction, and transverse direction, the cooking appliance comprising:
a cabinet defining a cooking chamber, the cooking chamber extending along the lateral direction between a first chamber side and a second chamber side;
a heating element mounted within the cabinet;
a first false wall slidably positioned within the cooking chamber at the first chamber side;
a second false wall slidably positioned within the cooking chamber at the second chamber side; and
a spit rod defining a rotation axis from a first rod end to a second rod end, the first rod end attached to the first false wall to slide therewith, the second rod end attached to the second false wall to slide therewith,
wherein the first false wall is slidable along the transverse direction independently from the second false wall.

2. The cooking appliance of claim 1 , further comprising a motor in selective mechanical communication with the spit rod to motivate rotation thereof.

3. The cooking appliance of claim 2 , wherein the motor is mounted to the second false wall to slide therewith.

4. The cooking appliance of claim 2 , wherein the spit rod is a first spit rod, wherein the cooking appliance further comprises a second spit rod spaced apart from the first spit rod along the vertical direction within the cooking chamber.

5. The cooking appliance of claim 4 , further comprising a plurality of chains connecting the motor to the first and second spit rods.

6. The cooking appliance of claim 1 , further comprising an interior sidewall fixed within the cabinet at the second chamber side, the interior sidewall defining a receiving slot extending therethrough along the lateral direction, wherein the second false wall is slidably disposed on the interior sidewall, wherein a rod sleeve extends through the receiving slot on the second false wall, and wherein the spit rod is secured to the second false wall on the rod sleeve.

7. The cooking appliance of claim 1 , further comprising a heat shield mounted within the cabinet rearward from the spit rod, the heat shield extending along a shield plane from a first end to a second end.

8. The cooking appliance of claim 7 , wherein the heat shield defines a vent channel extending from the first end to the second end.

9. The cooking appliance of claim 8 , wherein the heating element is aligned with the vent channel along the shield plane from the first end to the second end.

10. A cooking appliance defining a mutually-orthogonal vertical direction, lateral direction, and transverse direction, the cooking appliance comprising:
a cabinet defining a cooking chamber, the cooking chamber extending along the lateral direction between a first chamber side and a second chamber side;
a plurality of electric heating elements mounted within the cabinet;
a first false wall slidably positioned within the cooking chamber at the first chamber side;
a second false wall slidably positioned within the cooking chamber at the second chamber side, the second false wall being independently slidable relative to the first false wall;
a spit rod defining a rotation axis from a first rod end to a second rod end, the first rod end attached to the first false wall to slide therewith, the second rod end attached to the second false wall to slide therewith; and
a heat shield mounted within the cabinet rearward from the spit rod, the heat shield extending along a shield plane from a first end to a second end, wherein the heat shield defines a vent channel extending from the first end to the second end.

11. The cooking appliance of claim 10 , further comprising a motor in selective mechanical communication with the spit rod to motivate rotation thereof.

12. The cooking appliance of claim 11 , wherein the motor is mounted to the second false wall to slide therewith.

13. The cooking appliance of claim 11 , wherein the spit rod is a first spit rod, wherein the cooking appliance further comprises a second spit rod spaced apart from the first spit rod along the vertical direction within the cooking chamber.

14. The cooking appliance of claim 13 , further comprising a plurality of chains connecting the motor to the first and second spit rods.

15. The cooking appliance of claim 10 , further comprising an interior sidewall fixed within the cabinet at the second chamber side, the interior sidewall defining a receiving slot extending therethrough along the lateral direction, wherein the second false wall is slidably disposed on the interior sidewall, wherein a rod sleeve extends through the receiving slot on the second false wall, and wherein the spit rod is secured to the second false wall on the rod sleeve.

16. The cooking appliance of claim 10 , wherein a heating element of the plurality of electric heating elements is aligned with the vent channel along the shield plane from the first end to the second end.

17. A cooking appliance defining a mutually-orthogonal vertical direction, lateral direction, and transverse direction, the cooking appliance comprising:
a cabinet defining a cooking chamber, the cooking chamber extending along the lateral direction between a first chamber side and a second chamber side;
a heating element mounted within the cabinet;
an interior sidewall fixed within the cabinet at the second chamber side, the interior sidewall defining a receiving slot extending therethrough along the lateral direction;
a first false wall slidably positioned within the cooking chamber at the first chamber side;
a second false wall slidably disposed on the interior sidewall;
a rod sleeve extending through the receiving slot on the second false wall; and
a spit rod defining a rotation axis from a first rod end to a second rod end, the first rod end attached to the first false wall to slide therewith, the second rod end attached to the second false wall on the rod sleeve to slide with the second false wall.

18. The cooking appliance of claim 17 , further comprising a motor in selective mechanical communication with the spit rod to motivate rotation thereof,
wherein the motor is mounted to the second false wall to slide therewith.

19. The cooking appliance of claim 17 , further comprising a motor in selective mechanical communication with the spit rod to motivate rotation thereof,
wherein the spit rod is a first spit rod, wherein the cooking appliance further comprises a second spit rod spaced apart from the first spit rod along the vertical direction within the cooking chamber.

20. The cooking appliance of claim 19 , further comprising a plurality of chains connecting the motor to the first and second spit rods.
