Abstract

An oven with a baking chamber includes a crossflow fan with a connected cooling air duct configured to generate a cooling air stream that is exhausted to outside the oven. A vapor exhaust duct opening is included into the cooling air duct so as to exhaust vapors from the baking chamber therethrough. The vapor exhaust duct has an opening area disposed in an immediate vicinity of an exhaust area of the crossflow fan where a suction capacity for the vapors from the vapor exhaust duct is generated at a minimum rotational speed of the fan propeller.

Claims

1. An oven comprising:

a baking chamber,

a crossflow fan with a connected cooling air duct configured to generate a cooling air stream that is exhausted to the outside, and

a vapor exhaust duct opening into the cooling air duct at an opening area of the vapor exhaust duct so as to exhaust vapors from the baking chamber therethrough,

the opening area of the vapor exhaust duct being disposed downstream of a fan propeller of the crossflow fan in a direction of flow of the cooling air stream such that the exhaust vapors join the cooling air stream downstream of the fan propeller, and being disposed in an immediate vicinity of an outlet of the crossflow fan where a suction capacity for the vapors from the vapor exhaust duct is generated at a minimum rotational speed of the fan propeller.

2. The oven as recited in claim 1, further comprising an assembly part including an opening, and

wherein the crossflow fan includes a suction opening for the opening area of the vapor exhaust duct, the crossflow fan is disposed on the assembly part, and the opening of the assembly part corresponds to the suction opening of the crossflow fan.

3. The oven as recited in claim 1, further comprising an exhaust air duct connected to the exhaust area of the crossflow fan so as to carry away a mixed air stream of the cooling air and the vapors.

4. The oven as recited in claim 3, further comprising an assembly part including an opening, and

wherein the crossflow fan includes a suction opening for the opening area of the vapor exhaust duct, the crossflow fan is disposed on the assembly part, and the opening of the assembly part corresponds to the suction opening of the crossflow fan.

5. The oven as recited in claim 1, wherein the opening area is disposed relative to the crossflow fan so that the suction capacity is greatest at a maximum rotational speed of the crossflow fan.

6. The oven as recited in claim 5, further comprising an assembly part including an opening, and

wherein the crossflow fan includes a suction opening for the opening area of the vapor exhaust duct, the crossflow fan is disposed on the assembly part, and the opening of the assembly part corresponds to the suction opening of the crossflow fan.

7. The oven as recited in claim 5, further comprising an exhaust air duct connected to the exhaust area of the crossflow fan so as to carry away a mixed air stream of the cooling air and the vapors.

8. The oven as recited in claim 7, further comprising an assembly part including an opening, and

wherein the crossflow fan includes a suction opening for the opening area of the vapor exhaust duct, the crossflow fan is disposed on the assembly part, and the opening of the assembly part corresponds to the suction opening of the crossflow fan.
