Description

Description “Cooking device, furniture system, cooking device system and method for operating,”

The present invention relates to a cooking device, in particular a steam cooking device, preferably for integration into a furniture front, with at least one device body comprising at least one cooking chamber, at least one fan device and at least one air outlet opening for discharging air and/or vapors from the

Device body, wherein the cooking chamber and the air outlet opening have at least one

Air outlet section are operatively connected and wherein at least one air flow directed towards the air outlet opening can be provided in the air outlet section by means of the blower device. Furthermore, the present invention relates to a furniture system, a

Cooking system and a method for operating a cooking system.

There are a variety of different cooking devices, such as ovens

Microwave ovens and/or steam cookers, with a cooking chamber for cooking

Foodstuffs and/or foodstuffs which have been found to be particularly

Can be integrated into a furniture front such as a kitchen unit.

Such known cooking devices often have at least one air outlet and/or at least one ventilation system in order to ensure that the cooking process is carried out before, during and/or after operation of the

Cooking device air and/or vapors, in particular by means of one of at least one

To at least partially remove the air flow provided by the fan device from the cooking chamber.

In order to minimize or even completely prevent the entry of moisture, fats and/or odors contained in the air and/or the vapors into the surroundings of the cooking facility, the air and/or the vapors discharged from the cooking chamber are typically circulated in a recirculation mode, e.g. by means of a filter and/or

Catalyst device, at least partially cleaned and/or mixed with fresh air and/or discharged to the outside in an exhaust air operation by means of a discharge line.

Such known cooking devices with an air outlet and/or ventilation system work largely reliably. The disadvantage of the known systems, however, is that their

Installation and/or operation is associated with considerable costs and/or effort. For example, filter systems must be regularly maintained, cleaned and/or replaced and/or use considerable amounts of energy and/or other resources, such as water, during operation. In addition, installing a drainage line is often not very energy-efficient and/or can only be implemented with considerable effort, particularly in private homes.

It is therefore the object of the present invention to provide a cooking device which enables a user-friendly and reliable removal of air and/or vapors from the cooking chamber, in particular with a compact design and/or energy-efficient operation of the cooking device.

This object is achieved by the cooking device with the features of claim 1, the

Cooking system with the features of claim 13, the method for operating a cooking system with the features of claim 14 and the furniture system with the features of claim 16. Preferred developments of the invention are
