Definitions

  • the invention relates to a device for the discharge of air according to the preamble of claim 1.
  • Such devices for the discharge of air are used in particular in kitchens in order to extract and remove the cooking fumes which arise over a cooking place or a stove, if necessary to clean them (for example to filter them) and to return them to the room.
  • extractor hoods When used in kitchens are so-called extractor hoods.
  • Extractor hoods can be divided into two groups, depending on the type of air duct.
  • exhaust hoods the exhaust air is led through a pipe to the outside and thus removed from the room with cooking and exhaust hood and discharged to the atmosphere outside the building.
  • Grease separation is usually also provided for exhaust hoods. With these extractor hoods odor nuisance and dirt deposits in the cooking area and in the building can be avoided altogether.
  • forced draft hoods the air sucked in by the extractor hood is additionally cleaned of odorous substances by a filter or similar device and then returned to the cooking space.
  • Conventional extractor hoods of both groups generally have a separating device for separating the dirt particles and a fan or a blower device for generating an air flow and for removing the exhaust air.
  • the deposition of the dirt particles can take place by means of deposition elements and / or a suitable guidance of the air flow.
  • the separation device removes almost all contained solids from the exhaust air, such as grease and dirt particles, before the exhaust air enters the fan unit.
  • the exhaust air or the vapor is taken into an intake opening in an intake region of the exhaust hood in this.
  • the intake area here the entire area is referred to, which faces the exhaust air source.
  • the inlet opening is located in this hood near the front area, wherein a free side of the hood is defined as the front area, which does not border on a wall of the room and on the example, controls are mounted, which can be reached by a person cooking on the front side.
  • the invention has for its object to provide an apparatus for discharging air according to the preamble of claim 1, wherein condensate formation is restricted or avoided in the intake.
  • at least one second outlet opening provided in the suction either centrally or near a - the at least one free end region opposite side wall, wherein the at least one second outlet opening is formed so that an exiting fluid stream sweeps over the suction area and can be sucked through the at least one slot-shaped inlet opening.
  • the invention is consequently applicable, on the one hand, to wall hoods having a front region and an inlet opening.
  • these wall hoods have a second outlet opening which is provided in the suction area near a side wall opposite the one free end area, wherein the one second outlet opening is designed so that an exiting fluid flow passes over the suction area and through the one slot-shaped inlet opening is sucked.
  • the invention is also applicable to island hoods with at least two end regions and at least two inlet openings.
  • These island hoods according to the invention have a plurality of second outlet openings which are provided centrally in the suction region, wherein the plurality of second outlet openings are formed such that the exiting fluid streams sweep the suction area and can be sucked through the plurality of slot-shaped inlet openings.
  • the at least one fluid stream forms a layer below the intake region and in this way prevents ascending moist exhaust air from coming into direct contact with the intake region.
  • the ascending exhaust air is deflected and moved with the fluid flow in the direction of the inlet opening. Failure of moisture is thus prevented. Should it sometimes come to the formation of small water droplets, they are again evaporated by the fluid flow and the intake area is dried again.
  • cooker hoods work most effectively when a very high air velocity is achieved at the boundary between the exhaust air source and the open space. It should therefore be generated in this area a quasi upwardly flowing, fast moving air curtain over the entire width of the hood.
  • the at least one inlet opening is therefore slot-shaped, is parallel to the at least one free end region and extends almost over the entire width of the at least one free end region.
  • the fluid flow should prevent the direct contact of the exhaust air with the intake, on the other hand, he must not accelerate the entrained exhaust air so that it is pushed beyond the inlet opening and therefore can not be sucked through this.
  • the fluid flow emerging from the at least one second outlet opening is therefore dimensioned according to the invention such that the fluid flow is between 2% and 10%, in particular between 3% and 5%, of the volume flow of the sucked-off exhaust air in the blow-off channel.
  • the exact ratio between the volume flow of the sucked exhaust air and fluid flow depends on the design conditions of the exhaust hood such. As size of the intake, inclination of the intake, guiding the partial flow before exiting the second outlet opening, dimensioning of the second outlet opening, etc ..
  • the fluid flow can be generated by its own fan, which sucks either air from the outside of the building or air from the room.
  • the apparatus technical effort is relatively high in both cases. It is therefore advantageous in the flow direction after the fan device, a partial device for dividing the volume flow of the sucked exhaust air provided. It can be achieved in this way, a good result without additional fan. Furthermore, an automatic adaptation of the fluid flow to the volume flow of the intake exhaust air can thus be realized without additional control effort.
  • At least one first exhaust duct for guiding a first partial flow of the sucked exhaust air and at least one second exhaust duct for guiding a second partial flow of the sucked exhaust air is provided, wherein the first partial flow and the second partial flow are separable from each other by means of a separating element.
  • the separating element may for example be designed as a simple separating plate on the Abblasseite the fan device.
  • the first partial stream of the sucked in exhaust air, the actual main stream can then be supplied to the first outlet opening, from which it is either directed to the outside of the building or returned to the room via an odor filter, in most cases an activated carbon filter.
  • the second exhaust air duct deflects the partial flow and leads it to the at least one second outlet opening.
  • the deflection should be such that as little flow energy as possible is destroyed. In this case, a deflection of about 180 ° is necessary directly after the fan device. Before the mouth of the second exhaust duct in a second outlet opening, a further deflection must be made, which ensures that the fluid flow is not directed vertically downwards, but sweeps the intake.
  • the at least one second outlet opening is therefore formed in a slot shape.
  • the second outlet opening advantageously runs parallel to the suction opening and has approximately the same length. As a result, the entire fluid flow emerging from the second outlet opening can be absorbed by the suction opening.
  • the fluid flow is intended to detect the entire moisture laden rising exhaust air.
  • the gap of the at least one second outlet opening therefore extends parallel to the side wall opposite the at least one free end region. If the device is designed as a wall hood, the distance of the gap to the wall to which the device is attached should be as small as possible.
  • the width of the gap must be dimensioned so that the available volume flow in the second exhaust duct generates a fluid flow below the intake, the speed of which is large enough to guide the ascending exhaust air to the intake without it on the intake to over to press.
  • the width of the gap is between 2 and 5 mm. It depends mainly on the volume flow in the second exhaust duct.
  • the suction region advantageously has at least two partial surfaces, which together form an obtuse angle.
  • the edge in the front area of an extractor hood can be pulled upwards so that this edge projecting into the room does not hinder the headroom of a person who cooks.
  • the part of the intake area of this head clearance hood which is directed towards the forehead area is consequently not only the exhaust air source but also facing the cooking person, the vertical pointing to this part of the area between the exhaust air source and the person cooking. Care must be taken with these cooker hoods that condensate does not form on the intake area. Condensed water would run down the sloping surface and collect at the joint edge of the two faces. Since this connecting edge is a drip edge, the risk that water droplets dissolve at this point is particularly large. The fluid flow must therefore be particularly well matched to the construction of these overhead hoods.
  • the so-called island hoods are used over cooking islands in the room, which are accessible from at least two sides. These extractor hoods therefore also have two opposite end areas.
  • two slot-shaped inlet openings are provided on two opposite sides of the suction area and two second outlet openings are provided in the middle between the two slot-shaped inlet openings.
  • two fluid streams are to be generated in the middle, which are directed outwards from the center in opposite directions.
  • the second outlet openings are therefore designed such that the respectively exiting fluid flow sweeps over the suction area between the respective second outlet opening and the nearest inlet opening in such a way that it can be sucked through this closest inlet opening. This ensures that captured and sucked in both ascending exhaust air, but also a condensation between the two intake ports is avoided.
  • the suction region advantageously has three partial surfaces, wherein the outer partial surfaces each form an obtuse angle with the central partial surface and the inlet openings are provided in the outer partial surfaces and the second outlet openings in the central partial surface.
  • Fig. 1 shows an embodiment of an inventive device 1 for discharging air, in particular exhaust air 5, from an exhaust air source (here a cooking pot 6).
  • the device 1 can be provided as an extractor hood, for example as an exhaust hood or a circulating air hood.
  • an exhaust hood which has no odor filter. Since the extractor hood 1 has only one end region 21 and is fastened with its rear wall 3 to a room boundary wall 4, this is a so-called wall hood.
  • the device 1 designed as an extractor hood comprises a housing 2 with a front region 21, a side wall (rear wall 3) opposite the end region and an intake region 20.
  • the intake region 20 is the entire underside of the extractor hood 1, which faces the exhaust air source 6, wherein the Exhaust air source 6 eg on a cooktop or stove (not shown here) stands.
  • the suction region 20 in this embodiment two angularly adjacent faces 20a and 20b, wherein the partial surface 20a is aligned horizontally.
  • the partial surface 20b is arranged so that the edge furthest in the space in front of the extractor hood is at the greatest possible height.
  • a slot-shaped inlet opening 30 is provided, so that the air or exhaust air 6 provided for discharging can be sucked in.
  • the inlet opening 30 runs parallel and at a small distance to the edge of the partial area 20b of the intake area which projects furthest into the space. This arrangement ensures that also all vapors emanating from the cooking pot 6 can be detected and does not flow past the suction area 20 into the room.
  • the extractor hood 1 is in the flow direction after the inlet opening 30 formed with positive guidance means separating device 40 (see Fig. 4 ), which serves to separate suspended particles from the exhaust air.
  • the exhaust air flow is passed through the forced guidance means so that the exhaust air flow undergoes a strong deflection. Similar to a cyclone, the mass particles, such. B. condensed water droplets, dirt particles or fat ponds pressed outwards and settle on the forced guidance means.
  • the cleaned exhaust air stream continues to flow in the direction of the fan device 50.
  • the exhaust air stream sucked in via the inlet opening 30 scarcely has any suspended particles after passing through the separation device 40, so that the fan device 50 only comes into contact with exhaust air that is exposed to very little stress and thus can not become dirty.
  • the fan device 50 builds in the exhaust air conveying channel to a negative pressure, which pulls the cleaned exhaust air from the separator 40. In the flow direction after the fan device 50, the blow-off channel 61 is provided. This leads the entire sucked exhaust air and forms the volume flow L.
  • the exemplary embodiment shown is an exhaust hood in which the exhaust air conveyed by the fan device 50 is conducted without filter to the outside of the building, there is hardly any pressure rise after the fan device 50, via which a separation of the volume flow L into two partial streams would be executable. It is therefore a separator 70 is provided which divides the blow-off 71. The separation is thus achieved in this embodiment, the flow of the volume flow L.
  • the separating element 70 is aligned parallel to the flow direction of the volume flow L and divides the blow-off 61 at its upper end so that a first exhaust duct 62 and a second exhaust duct 63 arise.
  • the first exhaust duct 62 leads to a first outlet opening 31, while the second exhaust duct 63 leads to a second outlet opening 32.
  • the separating element 70 is arranged such that the first exhaust air duct is charged with about 97% of the volume flow L and the second exhaust air duct 63 with about 3% volumetric flow L.
  • the resulting primary flow L1 in the exhaust duct 62 thus behaves approximately equal to the resulting secondary flow L2 in the second exhaust duct 63, such as 32: 1.
  • This ratio ensures that the fluid flow F2 emerging from the second outlet opening 32 forms a kind of barrier layer below the suction area 20, which prevents the direct contact of the ascending exhaust air 5 with the suction area 20. It can therefore also condense out of the rising vapors moisture at the suction 20 and drop, for example, in the pot below. At the same time, however, this ratio also prevents the fluid flow F 2 from being so strong that it drives beyond the inlet opening and the ascending exhaust air 5 in the front region 21 leads past the extractor hood 1.
  • the first outlet opening 31 is formed by the exhaust pipe 33.
  • a hose can be attached, which leads via a wall opening directly into the open.
  • the second outlet opening 32 is provided on the underside of the extractor hood 1 in the suction region 20 facing the exhaust air source 6. Via the second outlet opening 32, the fluid flow F2 exits the housing 2 of the extractor hood 1.
  • the second outlet opening 32 forms a slot which is arranged parallel to the inlet opening 30 and extends close to the rear wall 3.
  • the slot is designed so that the exiting fluid flow F2 is inclined at approximately 15 ° to the horizontal. As a result, the exiting fluid flow F2 passes over the intake area in its entire width and is again completely sucked out through the likewise slot-shaped inlet opening 30.
  • the separating element 70 is provided here as an angled element, so that the secondary flow L2 divided by the volume flow L is directed out of the ventilating device 50 into the second exhaust air duct 63.
  • an angle of about 45 ° is provided here (see Fig. 3 ), so that the secondary flow L2 does not bounce here on a wall perpendicular to the flow direction.
  • the second exhaust duct 63 extends between the rear wall 3 of the hood 1 and a wall of the housing of the fan device 50, or it is formed by these walls and the side walls of the hood 1 not visible in the sectional view.
  • the cross section of the first exhaust duct 62 is larger than the cross section of the second exhaust duct 63, since the main part of the volumetric flow L is actually to be blown out via the first outlet opening 31, while only a small part is to be blown out of the second outlet opening 32.
  • the fluid flow F2 Since 40 water droplets, which are condensed out of the exhaust air 5 due to cooling, have already been deposited by the separator, the fluid flow F2 is relatively dry and can even absorb moisture again. This is particularly important if the hood was turned on only after the start of cooking and have already formed drops of water at its intake 20. These drops of water are then degraded slowly by the fluid flow F2 again, so that even a drying of the suction 20 is possible.
  • Fig. 2 shows the distribution of the volume flow L in the primary stream L1 and the secondary stream L2 from the embodiment according to Fig. 1 in detail.
  • the separating element 70 which is arranged so that the secondary flow L2 is separated without back pressure, since the separating element is immersed in parallel in the volume flow L. Only in the upper region, the separating element 70 is angled, so that the direction of the secondary current L2 is influenced and changed. Due to the 180 ° deflection of the secondary flow L2, a slight back pressure arises to the left of the separating element 70, which influences the ratio between primary flow L1 and secondary flow L2, which, however, can be taken into account when positioning the separating element 70.
  • FIGS. 3a and 3b illustrate the transition from the guided secondary flow L2 through the second outlet opening 32 in the only guided through the suction region 20 fluid flow F2.
  • the second outlet port 32 is provided in the horizontally oriented partial surface 20 a of the suction region 20 near the rear wall 3. It is oriented so that an inclined at an angle to the horizontal fluid flow F2 arises, which moves along the bottom of the intake. It forms a barrier layer which prevents rising exhaust air 5 from direct contact with the intake area.
  • the fluid flow F 2 flows around the edge between the partial surfaces 20 a and 20 b and moves toward the slot-shaped inlet opening 30.
  • the obliquely upwardly directed partial surface 20b may be provided with a decorative element 24, e.g. Example, be provided with a glass pane in which a recess for the inlet opening is provided.
  • the disc can be provided as a flat surface or as a curved element.
  • a heater could be provided at the intake to prevent the formation of condensate or eliminate condensate.
  • certain coatings may be provided for the partial surfaces or for the decorative element, which counteract condensation through the vapors.
  • Fig. 4 shows in detail the area of the partial surface 20b in which the inlet opening 30 is provided. It can be clearly seen here the recess in the decorative element 24.
  • the separation device 40 has a strongly curved surface, so that the exhaust air flow undergoes a strong deflection. During this deflection, the solid and liquid components of the exhaust air migrate to the outside and settle on the curved surfaces.
  • a second embodiment of the invention is shown.
  • it is a circulating hood 7, which is designed as island hood.
  • an odor filter 13 is provided, which the exhaust air has to flow through first.
  • This odor filter 13 has a layer of activated carbon, through which the exhaust air must pass.
  • An island hood is usually used over a cooking island that can be worked from two sides.
  • the extractor hood 7 therefore has two opposite end areas.
  • the end region 21 a and 21 b are formed symmetrically.
  • the suction region 20 is subdivided here into three partial surfaces, a middle, horizontally oriented partial surface 20a and two symmetrically formed partial surfaces 20b and 20c adjoining on both sides.
  • the two outer partial surfaces 20b and 20c are - as in the embodiment according to Fig. 1 - pulled upwards to give a user more headroom and a clear view of the stove surface.
  • the extractor hood 7 has two inlet openings 30a and 30b, each of which is arranged near the respective free end region 21a and 21b.
  • the exhaust air 5 is consequently - in contrast to the embodiment of Fig. 1 - Suctioned on both sides of the hood 7.
  • the second exhaust duct 63 is here guided so that it can supply two second outlet openings 32a and 32b in the central part surface 20a with the secondary flow L2.
  • the two second outlet openings 32a and 32b are located in the central part surface 20a and are designed such that in each case a fluid flow F2a or F2b is formed in the direction of the end region 21a or 21b.
  • the second outlet openings 32a and 32b are thus located centrally in the intake area 20 with only a small distance from each other.
  • the two outwardly directed fluid streams also entrain exhaust air, which would otherwise impinge on the central partial surface 20a between the two second outlet openings 32a and 32b and possibly leave water droplets there.
  • the two fluid flows F2a and F2b are in each case sucked off via the corresponding inlet opening 30a or 30b.
  • the fan device 50 is designed here so that sufficient exhaust air 5 can be sucked off via both inlet openings 30a and 30b.
  • Fig. 6 shows the separation into the primary stream L1 and the secondary stream L2 in detail. Due to the flow resistance of the filter 13, a dynamic pressure builds up between the fan device 50 and the filter 13. As a result of this dynamic pressure, exhaust air is forced into the second exhaust air duct 63 even without a separating element.
  • the ratio between primary current L1 and secondary current L2 is set here exclusively via the ratio of the input cross sections.
  • Fig. 7 is shown again in detail the generation of the two fluid flows F2a and F2b.
  • the respective second outlet opening designed so that the fluid flow is directed obliquely downwards.
  • the invention is, of course, also applicable to extractor hoods whose suction region facing the exhaust air source has only a horizontally oriented surface, which are therefore not designed as headlamp hoods.
