Definitions

  • the invention relates to an extractor hood with at least one grease filter and with air guiding means for generating an air stream falling on the grease filter according to the preamble of claim 1.
  • Fat filters for extractor hoods have e.g. a filter plate having a plurality of openings. In the area of these openings water and fat drops are separated from the haze.
  • the object is to improve the efficiency of such grease filters.
  • the filter plate is equipped with deflecting elements. These are designed so that air is deflected asymmetrically in a first direction along the filter plate.
  • first direction along the filter plate is to be understood as meaning that direction parallel to the filter plate, against which air perpendicular to the filter plate is deflected.
  • the filter plate is arranged so that the incident on the filter plate air flow has a velocity component counter to the first direction.
  • the extractor hood according to Fig. 1 is intended to be arranged above a cooking position and has an inlet region 1, which receives the rising steam upwards.
  • a horizontal baffle plate 2 is arranged, at which the steam is stowed and directed to the outside.
  • the baffle plate 2 is surrounded by walls 3, wherein on at least two, preferably three or four sides of the baffle plate entrance gaps 4 between the baffle plate 2 and the walls 3 are provided.
  • the steam enters the space above the baffle plate 2 through the entrance slits 4. As indicated by arrows 5, it is guided by the sloping, upwardly converging walls 5 against a grease filter 6 out.
  • the grease filter 6 is arranged above the inlet region 1 and the baffle plate 2.
  • a fan 11 may be arranged, which pulls the vapor through the hood.
  • FIG. 2 The structure of the filter plates 8 and filter body 9 is shown in FIG. 2. It is one each Filter plate 8 connected to an associated filter body 9 into a unit, wherein the steam passes first through the filter plate 8 and then through the filter body 9.
  • Each filter plate 8 is preferably made of an expanded metal sheet or a stamped and deep-drawn sheet metal body. As shown in FIGS. 2 and 3 (wherein FIG. 3 shows the filter plate 8 of FIG. 2 obliquely from above), a plurality of openings 13 are provided in the filter plate 8. Adjacent to each opening (or at least a part of the openings), a part 14 of the sheet is deformed upward and forms a deflecting surface 15, which deflects the haze in a manner to be described as a deflecting element.
  • the filter body 9 also has a plurality of openings which allow the steam to pass through the filter body 9.
  • the openings of the filter body 9 preferably have a smaller diameter than the openings 13 of the filter plate 8.
  • the filter body 9 is preferably thicker than the filter plate 8. Also in the filter body 9 there is a deflection of the vapor stream, but the deflection direction from place to Can change location.
  • the filter body 9 may e.g. consist of several layers of expanded aluminum metal or nonwoven, while the filter plate 8 is made of aluminum or chrome steel expanded metal.
  • the filter plate 8 has an asymmetrical structure, which leads to a one-sided deflection of the vapor against a first, preferred direction X out. This is illustrated in FIG. 4 on the basis of an imaginary air flow 16, which hardly occurs in normal operation and which flows vertically. As can be seen, all the deflection surfaces 15 extend obliquely in the same direction away from the plane of the filter plate 8, so that occurring air is deflected in the direction indicated in FIG. 4 as X.
  • the direction X is referred to in the claims as "first direction”.
  • Each deflecting surface 15 is disposed on each one of the openings 13, on the side of the opening opposite the direction X, so that the air passing through the opening 13 strikes the deflecting surface 15 and is deflected against the direction X.
  • the air In normal operation, the air is not perpendicular, but obliquely at an angle ⁇ ⁇ 90 ° on the filter plate 8, as shown in FIGS. 2 and 5 is illustrated.
  • ⁇ ⁇ 90 ° on the filter plate 8 For the oblique incidence provide air conduction of the hood, which are formed in the embodiment of Fig. 1 primarily from the horizontal baffle plate 2 and the walls 3 of the upwardly to the grease filter 6 towards tapered hood.
  • the air entering through the mutually opposite inlet gaps 4 runs along the two walls 3 which converge obliquely and falls obliquely onto the filter plates 8.
  • FIG. 5 shows the mean incidence velocity v of the air incident on the filter plate 8 at an angle ⁇ .
  • the velocity v has a velocity component v1 parallel to the direction X and a velocity component v2 perpendicular thereto.
  • the filter plate 8 is now arranged so that the direction X is opposite to the velocity component v1. This leads to a relatively strong deflection at the deflection surfaces 15, which favors the deposition of fat and water drops.
  • the velocity v and the unit vector n X are along the X direction in a common plane perpendicular to the filter plate 8.
  • deviations are allowed as long as the component v 1 is antiparallel to n X. This is guaranteed if the scalar product n X ⁇ v is negative.
  • the air flow incident on the filter plate 8 has a velocity component opposite to the first direction.
  • the filter plates 8 can be removed together with their filter bodies 9 from the hood. However, they can be used, thanks to suitable mechanical design (not shown), only in such a way that the air flow incident on the filter plate has a velocity component counter to the direction X, as shown in FIG.
  • an oblique or vertical arrangement of the filter plates 8 can favor an oblique incidence of the steam on the filter plates.
  • Fig. 6 shows, for example, the arrangement of two filter plates 8 with associated filter bodies 9 in oblique, upwardly running together position, according to the arrangement of FIG. 1st
  • Fig. 7 shows a second arrangement of the filter plates 8 with the associated filter bodies 9.
  • the filter plates are arranged in a pyramid shape. This version is particularly suitable for free-hanging cooker hoods with four walls 3 converging towards the grease filter.
  • FIG. 1 A similar embodiment is shown in FIG. Here, however, the filter plates 8 are arranged vertically.
