Definitions

  • the invention relates to an extractor hood according to the preamble of claim 1.
  • Such an extractor hood is known from DE-OS 1 454 643.
  • suction is carried out either over the entire or a partial area per unit area of the surface of the suction area.
  • the flow rate can thus be increased, but an increase in the suction area per surface unit by a factor of 1 is not shown.
  • Extractor hoods are also known from DE 33 06 140 C2 or DE-U 93 13 542.4. They are preferably used to extract steam that is produced, for example, when cooking. Grease and odor filters are often used to filter the intake air, after which the filtered air is blown out directly into the room. Alternatively, there is the possibility that the haze-laden air is sucked in with the aid of a blower, passes through a filter unit and is then blown outwards via a discharge line forming the air flow path. The fan is either integrated in the extractor hood or on another Place in the airflow path. Such extractor hoods are either integrated in wall cabinets above the extractor source or are also increasingly used for free-standing extractor sources, so that they are arranged in a self-supporting manner in the room.
  • the present invention has for its object to develop a range hood of the type mentioned in such a way that condensation is reduced.
  • a filter suction is combined with an edge suction. While the filter suction, which is preferably arranged centrally above the vapor source, draws off the immediately rising vapors, the flow speed is increased in particular in the edge region so that a return effect of the air to be extracted occurs. Even fumes, which tend to move past the extractor hood, especially when there is a cross flow in free-standing cooking zones, can be extracted. Due to the relatively high flow rate, the use of fans with a lower fan output is also possible.
  • the effect of the speed-increasing measures can be improved in that the suction opening is round, the diameter of the suction opening being approximately the same as the diameter of the Extraction line corresponds.
  • the increased air speed in the edge area by the edge suction then also leads to an increased speed in the discharge line in the edge area, which supports the formation of a laminar flow and thus reduces friction losses.
  • the flow speed can be increased in a targeted manner, for example by tearing edges, and the flow can be kept in the laminar area if necessary.
  • an extractor hood is shown, which is usually arranged above at least one extractor source, such as above a kitchen range. Act in the specific embodiment it is a cooker hood for free-standing hobs, but other designs of the cooker hood are possible.
  • Such extractor hoods usually have a suction surface 11 with first suction openings 11a. From this suction surface, the vapors reach an exhaust line 12 along an air flow path.
  • a blower is used at any point in the air flow path, which is preferably designed to be pressure-stable in order to be able to extract the required amounts of air.
  • a filter element 13 is arranged in the air flow path behind the suction surface 11.
  • depressions 14 with additional suction openings 11b are provided in the area of the suction surface, the cross-sectional area of which is greater than the area that the depressions 14 have in the suction surface 11.
  • the depressions 14 are only arranged at the edges and the additional suction openings 11b are only located on the radially inner side of the recess designed as a radial groove, but the depressions can also be arranged at any other points in the region of the suction opening in such a way that additional suction openings are provided are provided on both sides or at the bottom of the recess.
  • the sucked-in air is preferably passed through the filter element 13. This allows the flow velocity to be increased in a targeted manner in certain areas.
  • FIG. 8 shows the arrangement of such depressions on the edge of the suction surface 11. This results in the possibility of a combination of a filter suction in connection with an edge suction.
  • the filter element 13 which is preferably dishwasher-safe.
  • the filter element of the hood which is almost flat in the filter area, is arranged directly behind the suction surface 11.
  • the filter cover 18 is fixed in a known manner on the extractor hood, for example by a bayonet catch.
  • the filter element 13 is on the wall 15c Cover 15 set.
  • the filter element 13 is a round filter that can be adapted to the curvature of the cover 15.
  • the circular filter is enclosed by the annular recess 14.
  • the diameter d of the round suction surface corresponds approximately to the diameter D of the exhaust line 12 according to FIG sucked air is also entrained and the formation of a laminar flow is facilitated.
  • the flow rate increased by the depressions 14 can be increased by reducing the filter size without loss of filter performance, since the loss of area is compensated for by the increased flow rate. Also in the area of the filter cover, the flow at the first suction openings 11a can be accelerated by providing tear-off edges 11c at least there, but possibly also in the edge area of the depressions, for the air flow drawn into the exhaust line 12.
  • the extractor hood preferably covers the extractor source symmetrically with the cover 15.
  • the cover 15 is curved under at least one radius of curvature R, in the zenith of which the suction opening 11 is arranged. This leads to a streamlined merging of the rising vapors, the radius of curvature being selected so that there is a return effect of the air to be extracted.
  • Light sources 16, preferably halogen spotlights, are arranged in the lower region of the curved cover 15. There they heat the ambient air or the surface of the cover 15, so that not only the air heated by friction due to the flow velocity, but also the air heated by the light sources has a greater water vapor absorption capacity.
  • the extractor hood is rectangular in the vertical projection. The light sources 16 are assigned to the corner regions of the rectangle.
  • the light from the light sources is concentrated in the area of the cooking area.
  • a control panel 17 is provided centrally in the front edge 15a for operating the extractor hood.
