Definitions

  • the present invention relates to a device for trough extraction of exhaust air generated on a hob.
  • the present invention has for its object to provide a trough extractor that overcomes the disadvantages inherent in the prior art.
  • the object is achieved by a trough deduction with the features of claim 1.
  • the impeller can also be designed in a size that allows a rotation frequency that does not lead to noise pollution, but nevertheless provides the required suction power.
  • the installation space required for the trough extractor according to the claims does not differ from that which is required according to the aforementioned prior art.
  • the trough deduction according to the invention advantageously allows the installation height to be minimized by virtue of the grease separating cartridge partially integrated in the fan housing and the two-part guide device fully integrated therein.
  • the impeller of the radial fan has a diameter ranging from 400 to 440 mm, and the impeller blades are curved backward with respect to a direction of rotation of the impeller.
  • the radial fan of the sophisticated bowl extractor not only provides the required suction power in a secured manner, it is at least as quiet as the conventional radial fans installed in the aforementioned prior art, the maximum diameter of which is 200 mm. Due to their backward curvature in relation to the direction of rotation of the impeller, the impeller blades are adapted to the flow profile of the intake air and are therefore more efficient than the usual and - in relation to the direction of rotation of the impeller - forward-curved impeller blades.
  • the number of second flow lamellae exceeds that of the first flow lamellae by a multiple; this multiple is preferably in a range from 6 to 15.
  • the annulus of a spiral fan housing has to increase continuously.
