Definitions

  • the invention relates to a kitchen ventilation hood with a housing that has a passage with an entry opening for one over at least one kitchen appliance during the Operation has rising fluid, the non-air Contains substances; with an aerosol separator arranged in the passage, an exhaust fan on the outlet side at the passage can be connected; and with one to the Subsequent entry opening, in the installed position of the hood largely horizontal and facing the operating side of the Kitchen appliances extending guide surface for the fluid.
  • Such a kitchen ventilation hood is widespread and available in the stores.
  • Your aerosol separator stretches in the installed position of the hood horizontally in the inlet opening of the housing to get out of through the exhaust fan fluid sucked in via the aerosol separator
  • To filter out aerosol which is usually next to air Water vapor, fat droplets and other floating parts as well contains gases expelled from the food when heated. Filtering out the aerosol is said to prevent be that it is in the subsequent suction channel and until it reaches the exhaust fan.
  • the effectiveness of a such kitchen ventilation hood is however with exhaust air volume flows, those after sensitive and / or latent heat loads arranged under the kitchen ventilation hood thermal kitchen appliances have been identified by themselves resulting low detection speeds at the bottom Very low hood rim.
  • Ventilation hoods are also known in other areas, that work according to the swirl flow principle (see e.g. SE 409178 or DE 3045299 A1) and either no separator included or coaxial within the swirl current limiting cylinder a hollow cylindrical filter through which the fluid flows after at least a significant part of those contained in the fluid Floating particles on the inside of the outer cylinder has struck down.
  • a hollow cylindrical filter through which the fluid flows after at least a significant part of those contained in the fluid Floating particles on the inside of the outer cylinder has struck down.
  • such a filter throttles the fluid flow also and thus increases the required Exhaust fan performance.
  • the invention has for its object a kitchen ventilation hood of the type mentioned at the beginning, which at low fan power over a larger part of the the kitchen device rising fluids detected and sucked and at the same time ensures effective aerosol separation.
  • the Housing forms a cylinder, in the wall of which the inlet opening in the longitudinal direction of the cylinder below the Guide surface extends that the aerosol separator at least forms a longitudinal section of the wall of the cylinder and that the base surfaces of the cylinder each have an outlet opening for the largely aerosol-free fluid upstream the exit side of the passage.
  • the aerosol separator can be constructed in a conventional manner be, preferably of close-knit, one on top of the other Wire mesh, between the layers of which intersect closely Metal strips are arranged.

  • a T suction pipe can be inserted into the cylinder with its longitudinal part radially through the cylinder wall and with its cross part coaxial to the outlet openings of the base of the cylinder.
  • a T-suction pipe also enables an extension of the cylinder in compliance with the shape and position of the Swirl current without appreciable increase in the performance of the Exhaust fan.
  • the lower edge of the Inlet opening at least two falling towards its ends Has sections. This results in between a higher inflow velocity than these sections at their ends. This prevents a lowering of the axially middle section of the swirl current and ensures accordingly uniform flow conditions over the entire Swirl current length.
  • the lower edge of the inlet opening can be replaced by a detachably fastened aperture.
  • the aperture can then against one to the respective application of the kitchen ventilation hood better adjusted aperture replaced become.
  • at least two such panels can be arranged side by side.
