Definitions

  • the invention relates to a fume hood according to the preamble of claim 1.
  • hoods are increasingly used in which the sucked exhaust air from the hob is performed in a recirculation mode back to the living room, which is also easier to implement. So far, especially in the cold seasons heated air was sucked out of the living room and then blown away to the outside.
  • a controllable flap arrangement is provided for diverting the cleaned air either through a conduit to the outside and / or through an outlet opening back into the living space.
  • an optimal and energy-saving control of extracted exhaust air from the hob can be achieved.
  • conventional hoods can not filter the exhaust air completely from fat particles, flavors and other residues, there is the problem that in a recirculation mode, the recirculated air into the living room is not completely cleaned.
  • the present invention is the object of the invention to provide a fume hood, by means of which the sucked off by cooking and returned by the recirculation mode back into the living room exhaust air is almost completely cleaned, even with respect to taste residues.
  • the at least one filter integrated in the hood part and / or an additional filter consists of such a material that it almost completely filters the fat particles contained in the exhaust air.
  • Fig. 1 shows a fume hood 10, which is arranged in particular on a hob and can be fixed to the top of a ceiling. But it could also be mounted in a conventional manner on a wall. It consists essentially of a hood part 15, a connecting above this channel housing 12 and a manifold 14 together. From the latter leads an indicated exhaust duct 13 to the outside and also are arranged at her outlet openings 14 'in the living space leading back. By means of a control, the exhaust air can thus either transported outwards or be returned to the living room.
  • This adjustability of the distribution device 14 is effected by a flap mechanism or the like, not shown in detail.
  • channel housing 12 In channel housing 12 are also known per se odor filter, for example cassette-shaped activated carbon filter 18, 19 exchangeably installed, by means of which on the one hand a significant reduction in noise of a motor 23 for the Verttilator and on the other an odor reduction is achieved.
  • odor filters could also be placed in the outlet openings 14 '.
  • the exhaust air generated as an aerosol which is composed of a mixture of air, gases, water vapor, fat particles and other liquid or solid suspended particles, these gases or particles with such filters 17, 18, 19 are not completely filtered, but in particular Fat particles and odor residues, which are recycled in a recirculation mode in the living room.
  • additional filters 20 are integrated in the hood part 15 above the exhaust filter, which consist of such a material that with them the fat particles contained in the exhaust air are almost completely filtered.
  • Fig. 2 shows one of the three exhaust filter 17 and the one above this arranged inventive filter 20.
  • Both filters 17, 20 are each held by a peripheral sides surrounding their frame 17 ', 20'.
  • This filter 20, which approximately completely filters the fat particles in the exhaust air, is made, for example, from expanded metal, metal wool, plastic or from a similar resistant material. By this choice of material, the respective filter 20 can be removed together with the lower exhaust filter 17 from the hood part 15 for cleaning and then used again.
  • These filters 17, 20 can be washed separately in a dishwasher and they have a long service life.
  • the existing metal filter 20 could also be composed of several layers and be dismantled to achieve better cleaning in the individual layers.
  • a filter 30 with preferably a frame 30 'according to the invention is arranged at the top, which filters the fat particles almost completely during the suction and is designed as a replaceable disposable filter. It is accordingly exchanged for a single or multiple use by a new filter 30.
  • the filter 30 with the frame 30 ' is advantageously releasably attached to the frame 17' of the lower exhaust filter 17.
  • This filter 30 is made of synthetic, glass-fiber or a similar material and it is shown in this two different structures, left is a wave-shaped filled fleece 31 and right a regularly folded sheet-like single-layer filter material 32 shown as variants.
  • the exhaust filter 17 is provided with the frame 17 ', while in each case above a filter 40 with frame 40' is arranged according to the invention, which is similar to the filter 30 is configured.
  • this multilayer filter layers 41, 42 are on the left and similar filter layers 43 arranged on the right one above the other, which can also be designed progressive.
  • Fig. 5 shows in the context of the invention, a filter 50 with frame 50 ', which in contrast to that after Fig. 2 as a filter element is formed, which is preferably suitable as a disposable filter and is accordingly made of a cost-effective material.
  • the filter 50 is similar to the one after Fig. 3 formed on the left of a regularly folded sheet-like single-layer filter material 52 and the right of a wavy filled fleece 51, this filter 50 advantageously has an approximately double thickness as the filter 30 or 40 to ensure the necessary filtration of the fat particles.
  • these filters 20, 30, 40 designed as disposable filters could be arranged additionally or only on the inflow side and held, for example, with a stabilizing braiding or rods.
  • disposable filters advantageously use recyclable materials.
  • these could be purchased by the user as a roll and cut to size and placed in the respective frame 30 ', 40', 50 '. It could be provided as needed, two or more superimposed disposable filter.
