Abstract

A fume extraction device for the downward extraction of cooking fumes comprises at least one inflow opening for the inflow of the cooking fumes, and at least one fan for suctioning the cooking fumes at the at least one inflow opening, such fan having a fan propeller that is mounted so as to be rotatable about a rotation axis, wherein the rotation axis is oriented so as to be inclined in relation to a horizontal plane and to a vertical direction.

Claims (26)

1. A stove top system comprising:

at least one cooking fume extractor for the downward extraction of cooking fumes, having

at least one inflow opening for the inflow of the cooking fumes; and

at least one fan for suctioning the cooking fumes at the at least one inflow opening, such fan having a fan propeller that is mounted so as to be rotatable about a rotation axis; and

a filter for filtering the cooking fumes, which is configured as a grease filter,

wherein the rotation axis is oriented so as to be inclined in relation to a horizontal plane and to a vertical direction; and

at least one heating unit for heating food,

wherein the at least one fan, when viewed in a plan view overlaps the at least one heating unit and when viewed in at least one of a lateral view and a front view, overlaps the at least one heating unit.

2. The stove top system as claimed in claim 1 ,

wherein an inclination angle between the horizontal plane and the rotation axis is in a range from 10° to 85°.

3. The stove top system as claimed in claim 1 ,

wherein a suctioning direction of the fan at a downstream end of a negative-pressure duct portion has an upward-pointing directional component.

4. The stove top system as claimed in claim 1 ,

comprising a negative-pressure duct portion which fluidically connects the at least one inflow opening to the at least one fan, wherein a duct centerline of the negative-pressure duct portion along the extent thereof has an absolute angular variation in a range from 100° to 170°.

5. The stove top system as claimed in claim 1 , comprising a control unit for controlling the at least one of at least one cooking fume extractor and the at least one heating element, wherein the at least one fan, when viewed in at least one of a plan view, in a lateral view and in a front view, overlaps the at least one control unit.

6. The stove top system as claimed in claim 1 , wherein a vertical overall height of the stove top system is at most 200 mm.

7. The stove top system as claimed in claim 1 , the at least one fan having a fan housing having a negative-pressure connector opening,

wherein the fan propeller is disposed in the fan housing;

wherein the rotation axis conjointly with a connector normal that is oriented so as to be perpendicular to the negative-pressure connector opening encloses a connector angle in a range from 10° to 85°.

8. The stove top system as claimed in claim 7 ,

wherein the connector angle is in a range from 30° to 80°.

9. The stove top system as claimed in claim 1 ,

wherein an inclination angle between the horizontal plane and the rotation axis is in a range from 30° to 80°.

10. The stove top system as claimed in claim 1 ,

wherein a duct centerline of the negative-pressure duct portion along the extent thereof has an absolute angular variation in a range from 120° to 150°.

11. The stove top system as claimed in claim 1 , having a food carrier wherein the at least one inflow opening, when viewed in the plan view, is disposed in a central region of the food carrier.
