Abstract

According to one example, a convection oven comprises a cooking chamber having a front door and a rear door opposing the front door; a combustion chamber disposed below at least a portion of the cooking chamber; a side flue conduit configured to direct hot air from the combustion chamber to the cooking chamber; and a side sub-chamber with a convection fan configured to re-circulate at least a portion of the hot air within the cooking chamber, in which the side sub-chamber is disposed adjacent a side of the cooking chamber that is orthogonal to the front and rear door.

First claim

What is claimed is:

1. A convection oven comprising:
a) a cooking chamber having a front door and a rear door opposing the front door;
b) a combustion chamber disposed below at least a portion of the cooking chamber;
c) a side flue conduit configured to direct hot air from the combustion chamber to the cooking chamber;
d) a side sub-chamber with a convection fan configured to re-circulate at least a portion of the hot air within the cooking chamber, in which the side sub-chamber is disposed adjacent a side of the cooking chamber that is orthogonal to the front and rear door;
e) a sub-housing positioned opposite the sub-chamber, the sub-housing including a motor configured to rotate the convection fan, and further including a cooling fan that is coupled to the motor and this is configured for exchanging air in the side sub-chamber; and
f) a means for drawing air into the sub-housing that comprises a sub-cavity positioned below at least one of a front and a rear portion of the cooking chamber, wherein the sub-cavity is vented to the exterior of the convection oven and is in fluid communication with a lower portion of the sub-housing.

2. The convection oven of claim 1 further comprising a means for venting air from the sub-housing.

3. The convection oven of claim 2 wherein the means for venting air from the sub-housing comprises a rear vent on a side of the sub-housing.

4. The convection oven of claim 1 wherein the sub-housing comprises one or more components for controlling the convection oven.

5. The convection oven of claim 1 further comprising at least one external control on an outside of the sub-housing that is adjacent the front door, wherein the external control modulates a component inside the sub-housing that controls at least one aspect of the operation of the convection oven.

6. The convection oven of claim 1 further comprising thermal insulation surrounding at least a portion of the cooking chamber and the combustion chamber that is adjacent to and external to the sub-housing.

7. The convection oven of claim 1 further comprising at least one external control on an outside of the sub-housing that is adjacent the front door, wherein the at least one external control modulates the speed of the motor.

8. A convection oven comprising:
a) a cooking chamber having a front door and a rear door opposing the front door;
b) a combustion chamber disposed below at least a portion of the cooking chamber;
c) a side flue conduit configured to direct hot air from the combustion chamber to the cooking chamber;
d) a side sub-chamber with a convection fan configured to re-circulate at least a portion of the hot air within the cooking chamber, in which the side sub-chamber is disposed adjacent a side of the cooking chamber that is orthogonal to the front and rear door;
e) a sub-housing positioned opposite the sub-chamber, the sub-housing including a motor configured to rotate the convection fan, and further including a cooling fan that is coupled to the motor and this is configured for exchanging air in the side sub-chamber;
f) at least one external flue conduit configured to direct a portion of combustion gas outside of the convection oven; and
g) a means for drawing air into the sub-housing that comprises a sub-cavity positioned below at least one of a front and a rear portion of the cooking chamber, wherein the sub-cavity is vented to the exterior of the convection oven and is in fluid communication with a lower portion of the sub-housing.

9. The convection oven of claim 8 further comprising at least one upper conduit to direct the portion of combustion gas from the cooking chamber to the at least one external flue conduit.

10. The convection oven of claim 8 wherein the at least one external flue conduit is disposed on an opposite side of the convection oven from the sub-housing.

11. The convection oven of claim 8 further comprising at least one external control on an outside of the sub-housing that is adjacent the front door, wherein the external control modulates a component inside the sub-housing that controls at least one aspect of the operation of the convection oven.

12. The convection oven of claim 11 wherein the at least one external control modulates the speed of the motor.

13. The convection oven of claim 8 further comprising thermal insulation surrounding at least a portion of the cooking chamber and the combustion chamber that is adjacent to and external to the sub-housing.
