Definitions

  • the present invention relates to a vapor screen device, in particular for use in a downdraft fan, comprising at least one intake section with at least one intake opening and at least one flat filter device, the intake section being delimited by at least one front wall and at least one rear wall.
  • the present invention also relates to a downdraft fan and a method for maintaining a vapor screen device and/or a downdraft fan.
  • Extractor hoods and/or downdraft fans are often installed above or around a hob in order to extract the fatty vapors that rise during cooking and thus prevent the kitchen elements from getting dirty and unpleasant odors developing.
  • the fatty vapors and the air that rise above a hob are typically sucked into an intake section by at least one fan, freed of fatty components and odors and then, depending on the design of the extractor hood or downdraft fan, fed to a recirculation and/or exhaust air mode.
  • Extractor hoods are often installed above and/or next to and/or around a hob in order to extract the fatty vapors that rise during cooking and thus prevent soiling of the kitchen elements and the development of unpleasant odors.
  • Downdraft extractors or table extractors are extractor hoods, which are usually integrated largely flush with their suction opening into a worktop and/or a hob. For this purpose, the fatty vapors rising above the hob are typically sucked into the suction opening, freed of fatty components and odors and downwards, especially underneath the worktop or hob is discharged to a fan.
  • Downdraft fans or table fans are used when there is no installation space above the cooktop or optical considerations speak against such an installation.
  • One or more downdraft fans or table fans can also be arranged around a hob or integrated into a hob.
  • the fan on a downdraft fan is located below the worktop so that the vapor is discharged below the hob.
  • the downdraft fan has a movable fume screen and/or other fume guiding elements, as a result of which the suction opening can be positioned above the hob when the downdraft fan is in operation. Due to the at least slightly raised arrangement compared to the hob, a better recording or a better to catch vapors and/or air. If they are not needed or not in use, such vapor screens can be moved under the worktop or hob and are then not visible or hidden.
  • fume hoods of downdraft fans should not only enable effective and powerful extraction of fumes, they must also be designed to be particularly space-saving, in particular due to the small installation space next to a hob.
  • a space-saving configuration of a fume hood usually requires a reduction in the filter size or the filter surface, which can then often result in insufficient cleaning or filtration of the sucked-in fumes to remove fat, moisture and odors.
  • the filters also often become clogged, particularly in vapor deflectors designed to save space, which can significantly reduce the suction power of downdraft fans. In order to avoid a drop in performance, the filters then often have to be cleaned and/or replaced at short intervals, which is laborious and laborious.
  • the vapor deflector device according to the invention is particularly suitable for use in a downdraft fan and comprises at least one suction section with at least one suction opening and at least one flat filter device, the suction section being delimited by at least one front wall and at least one rear wall.
  • the filter device is arranged in the intake section obliquely to the flow cross section of the intake section.
  • the filter device is preferably arranged in the intake section at an angle between the front wall and the rear wall.
  • oblique is to be understood in particular not as vertical and in particular not as horizontal either.
  • the intake section forms in particular an intake channel through which air and/or vapors can preferably flow.
  • the suction section comprises at least two lateral walls which connect the front wall and the rear wall to one another.
  • the front wall is in particular the wall which faces a hob device and/or a user.
  • the suction section includes at least one upper wall which closes off or delimits the suction section at the top.
  • the flow cross section is in particular a surface normal or perpendicular to the direction of flow of sucked vapors.
  • the flow cross-section is preferably provided by a largely horizontal plane, through which in particular vapors or air sucked in downwards through the intake opening flow.
  • the flow of vapors or air, directed in particular downwards, is preferably produced by means of a blower device.
  • the filter device is in particular a grease filter.
  • the filter device can also include other filters such.
  • B. include at least one odor filter 16, at least one moisture absorber or the like.
  • the vapor shield device preferably comprises further filters such as e.g. B. odor filter, moisture absorber or similar.
  • the intake section has a width-to-depth ratio of in particular less than 20, preferably less than 15, very particularly preferably less than 10, particularly preferably less than 8, preferably 5 and at most 3.
  • the width is given in particular by the length of the front wall and/or rear wall.
  • the depth is given in particular by the distance between the front wall and the rear wall.
  • the intake section preferably has a width-to-height ratio of in particular less than 15, preferably less than 10, very particularly preferably less than 8, particularly preferably less than 5, preferably 3 and at most 1.5.

  • a significant advantage is that the filter device is arranged in the intake section at an angle to the flow cross section of the intake section.
  • large and even very large flat filter devices can be arranged in the intake section of the vapor screen device and thus a particularly large filter area or filter surface for filtering the sucked vapor or the sucked air are provided. This results in a particularly good filter effect or a particularly effective filtering of the drawn-in vapor and/or the air of the vapor screen device according to the invention.
  • the filter device can also be designed to be relatively narrow or thin. This is particularly advantageous since the flow speed and/or the suction power provided by a blower device is largely not reduced or impaired, or only slightly so. This makes the vapor deflector device particularly efficient and, in particular, energy-saving.
  • the oblique arrangement of the filter device to the flow cross-section provides a large area, in particular a large area in front of the filter device, on which moisture in particular, such as fat and/or water from the fumes, can condense before the sucked-in fumes hit the filter device.
  • moisture in particular such as fat and/or water from the fumes
  • a considerable part of the fat and/or the water is already separated from the vapor before the vapor flows through the filter device. This relieves the filter device considerably and lengthens the time intervals at which the filter device has to be replaced and/or cleaned or maintained.
