Abstract

The disclosure provides a movable door that directs debris, such as oil, grease, and food particles, that falls from a plurality of cooking slots in a vertical cooking grill to an area separate from a food product delivery tray, providing a cooked food product with reduced calories that is potentially more visually appealing.

Claims (32)

1. A cooking unit, comprising:

a food product delivery area;

a cooking slot including an upper opening and a lower opening; and

a door between the food product delivery area and the lower opening of the cooking slot,

wherein the door has a first end that is attached to a fixed anchor position, and

wherein the door is routed around a first door support and a second door support, wherein the second door support is below the first door support, and

wherein the door is movable between a first position to block a direct path from the cooking slot to the food product delivery area, and a second position where a path is provided for food product to move from the cooking slot to the food delivery area, and in the first position the door includes an angled surface that is at an angle with respect to a horizontal direction and the angled surface extends continuously from the first door support to the second door support,

wherein the first door support is movable, and transverse movement of the first door support moves the door from the first position to the second position.

2. The cooking unit of claim 1 , wherein the door is formed of a flexible, food grade material.

3. The cooking unit of claim 2 , wherein the flexible food grade material is polytetrafluoroethylene.

4. The cooking unit of claim 1 , wherein the second door support is fixed.

5. The cooking unit of claim 4 , wherein during at least a portion of transverse movement of the first door support, the door contacts the second door support and an angle of the door changes.

6. The cooking unit of claim 4 , wherein the door includes a portion that extends below the second door support in a direction that is toward the food product delivery area, and the cooking unit includes a grease receptacle positioned vertically below the portion of the door that extends below the second door support.

7. The cooking unit of claim 1 , wherein the door includes a door section that is oriented at an angle to the angled surface, and as the door moves between the first position and the second position, the angle between the door section and the angled surface changes with movement of the door.

8. The cooking unit of claim 1 , further comprising a trap door having a trap door slot positioned between the cooking slot and the door, wherein the trap door is movable between a first trap door position that secures food product in the cooking slot and a second trap door position that provides a path for food product to move downwardly from the cooking slot.

9. The cooking unit of claim 8 , wherein the door is moved to the second position before the trap door is moved to the second trap door position.

10. The cooking unit of claim 8 , wherein the trap door includes an underside, and a portion of the door is positioned to contact the underside of the trap door during movement from the door first position to the door second position.

11. The cooking unit of claim 1 , wherein the door further comprises a second end that is below the second door support, and the unit further comprises a tensioner attached to the second end.

12. A cooking unit, comprising:

a food product delivery area;

a cooking slot including an upper opening and a lower opening; and

a door positioned between the food product delivery area and the lower opening of the cooking slot, wherein the door is made of a flexible, food grade material,

wherein the door is movable between a first position to block a direct path from the cooking slot to the food product delivery area, and a second position where a path is provided for food product to move from the cooking slot to the food delivery area, and in the first position the door includes an angled surface that is at an angle with respect to a horizontal direction and the angled surface extends continuously from a moveable first door support to a fixed second door support,

wherein transverse movement of the first door support moves the door from the first position to the second position, and

wherein the door comprises a lower end that is below the second door support, and the unit further comprises a tensioner attached to the lower end.

13. A cooking unit, comprising:

a food product delivery area;

a cooking slot including an upper opening and a lower opening;

a door positioned between the food product delivery area and the lower opening of the cooking slot; and

a trap door having a trap door slot between the cooking slot and the door, wherein the trap door is movable between a trap door first position that secures food product in the cooking slot and a second trap door position that provides a path for food product to move downwardly from the cooking slot,

wherein the door is movable between a door first position to block a direct path from the cooking slot to the food product delivery area, and a door second position where a path is provided for food product to move from the cooking slot to the food delivery area, and in the door first position the door includes an angled surface that is at an angle with respect to a horizontal direction and the angled surface extends continuously from a first door support to a second door support, and

wherein the trap door includes an underside, and a portion of the door is positioned to contact the underside of the trap door during movement from the door first position to the door second position.
