Abstract
A fume extraction device including a fan for extracting fume-laden air from a cooking device in a room to an area located outside the room. The fume extraction device includes a pressure differential detection device for detecting the pressure difference (Pd) between an inside pressure (Pi) in the room and the outside pressure (Pa) in the area located outside the room. The fume extraction device further includes a control device for controlling the air conveying capacity of the fan according to the (Pd).

1-15. (canceled)
A control device for use in a waste-air fume extraction device, comprising:
- a room;
- a cooking device in said room;
- a fan arranged in said room;
- a pressure difference detection device for detecting the pressure difference (Pd) between the inside pressure (Pi) in said room and the outside pressure (Pa) in the area outside said room;
- and
- a control device for controlling the air conveying capacity of the fume extraction device depending on the detected pressure difference (Pd).
A fume extraction device, comprising:
- a fan for extracting the fume-laden air from a room containing a cooking device and conveying the extracted air to an area outside said room;
- a pressure difference detection device for detecting the pressure difference (Pd) between the inside pressure (Pi) in said room and the outside pressure (Pa) in said area outside said room;
- and
- a control device for controlling the air conveying capacity of said fan depending on the detected pressure difference (Pd).
A method for operating a fume extraction device including a fan for extracting the fume-laden air from a room containing a cooking device and conveying the extracted air to an area outside the room, comprising:
- detecting the pressure difference (Pd) between the inside pressure (Pi) in the room and outside pressure (Pa) in the area outside said room;
- and
- controlling the air conveying capacity of the fan depending on said detected pressure difference (Pd).
