Abstract

A multiple oven, especially a double oven, with at least one lower oven and an upper oven arranged above it, features an upper fan for sucking in air over a surface of the upper oven, which features an upper vapor outlet, and also a lower fan for sucking in air over a surface of the lower oven, which features a lower vapor outlet. The multiple oven further features at least one vapor suction duct which is present for directing vapor exiting from the vapor outlet to one of the associated fans.

Claims

1. A multiple oven system, comprising:

a lower oven with a first vapor outlet in an upper exterior surface of the lower oven;

an upper oven located vertically above the lower oven, the upper oven including a second vapor outlet in an upper exterior surface of the upper oven;

an upper fan for sucking in air over a surface of the upper oven;

a lower fan for sucking in air over a surface of the lower oven;

a first ventilation bridge positioned on one of a portion of the upper exterior surface of the lower oven and a portion of the upper exterior surface of the upper oven, the first ventilation bridge directing vapor from one of the first vapor outlet and the second vapor outlet to a corresponding one of the upper fan and the lower fan; and

a first exhaust duct extending from the upper fan to a floor area of the system, the first exhaust duct extending along a rear side of the upper oven and a rear side of the lower oven,

wherein the first vapor outlet and the second vapor outlet are vertically aligned.

2. The system of claim 1, further comprising a second ventilation bridge that directs vapor from the other of the first vapor outlet and the second vapor outlet to a corresponding one of the upper fan and the lower fan.

3. The system of claim 2, wherein the first ventilation bridge and the second ventilation bridge are different.

4. The system of claim 3, wherein the lower fan is offset horizontally relative to the upper fan.

5. The system of claim 4, further comprising an exhaust duct having a vapor-free subduct and a vapor subduct.

6. The system of claim 5, wherein the first ventilation bridge directs vapor along a first path, and the second ventilation bridge directs vapor along a path that is shaped differently from the first path.

7. The system of claim 3, wherein the first ventilation bridge directs vapor along a first path, and the second ventilation bridge directs vapor along a path that is shaped differently from the first path.

8. The system of claim 1, wherein the lower fan is offset horizontally relative to the upper fan.

9. The system of claim 1, wherein the first ventilation bridge diverts the vapor horizontally.

11. The system of claim 1, wherein one of the upper fan and the lower fan is a crossflow fan.

12. The system of claim 1, further comprising an exhaust duct having a vapor-free subduct and a vapor subduct.

13. The system of claim 1, further comprising a second exhaust duct extending from the lower fan to the floor area of the system.

14. The system of claim 13, wherein the second exhaust duct extends along the rear side of the lower oven.

15. The system of claim 14, wherein the second exhaust duct is offset horizontally relative to the first exhaust duct.

16. The system of claim 1, wherein the first vapor outlet and the second vapor outlet are identical.

17. The system of claim 16, wherein the first ventilation bridge diverts the vapor horizontally.

18. The system of claim 1, wherein the first ventilation bridge substantially covers the one of the first vapor outlet and the second vapor outlet.

10. The system of 1, wherein the corresponding one of the upper fan and the lower fan maintains a separation between the vapor from the first ventilation bridge and the air being sucked in over a surface of the respective oven.
