Definitions

  • the invention relates to an extractor device for exhaust air operation according to the preamble of claim 1 and an extractor device for recirculation mode according to the preamble of claim 2.
  • Extractor hoods are generally used as built-in appliances or as extractor hoods or extractor fan known.
  • “Haze” is steam generated during cooking and / or baking, which is usually Fat particles or oil particles and other particles, for example Contains dust particles from the room from which the haze is extracted becomes.
  • the extracted extractor together with from the room, e.g. B. the kitchen, extracted air into the outside atmosphere of the building in which the room is formed.
  • a heat exchanger is preferably arranged for heat exchange between the two channels. In this way, the one with the extracted Haze and the extracted room air partially lost heat transferred to the cold air flow and thereby recovered in the kitchen.
  • Extractor hoods for recirculation mode are for example from DE 30 11 101 C2 known. There it is stated that the heat exchanger from Extractor hoods for exhaust air quickly through fat particles and oil particles from the extracted room air, if it is not contaminated by one Coarse filter with downstream activated carbon filter is protected from this. Further is often only the heat exchanger in the extractor hoods accessible with considerable effort or not at all. Therefore proposes this document to completely avoid a filter device, the heat exchanger in the suction space, d. H. at the upstream beginning of the Arrange extractor device and a cooling of the heat exchanger outer surface only to the extent that no fat and oil particles are present it can become hard and stick, but remain fluid and drain can.
  • an extractor hood is from the utility model DE-GM 78 02 041 U1 known, which either on recirculation mode or exhaust air mode is switchable. It has neither a cold air path to supply outside air another heat exchanger device in the room.
  • the fume extraction air stream cleaned by a filter device contains various Kitchen smells. That is why it is with recirculating extractor hoods known, in the fume extract air flow downstream of a grease filter also arrange an odor filter. With extractor hoods such odor filters are not used. They essentially exist from activated carbon or zeloith.
  • DE 30 11 101 C2 take the view that in an exhaust fume extractor, the is known from US 37 99 045 for filtering fat and oil particles a coarse filter with a downstream activated carbon filter is necessary, but it is not intended to filter odors, but only by filtering out fat and oil particles.
  • the object of the invention is to be achieved with extractor hood devices the efficiency of odor filters on simple and inexpensive Way to improve significantly.
  • This object is achieved according to the invention in that the odor filter in the extractor airway downstream after a heat exchanger device is arranged.
  • the heat exchanger device serves the Extractor fan air flow to cool by a cooling air flow, its temperature is lower than the temperature of the extractor air flow.
  • the extractor air flow in the odor filter has a lower temperature than in the prior art.
  • the maximum amount of moisture that can be absorbed the lower the temperature of an air stream, the lower its temperature is.
  • Embodiments require a cooling air flow and a heat exchanger.
  • the cooling air flow can be a temperature that usually occurs in a kitchen to have. It is only essential that it is lower than the temperature of the extractor air flow.
  • the invention offers not only for circulating air extractor devices, but also significant advantages for extractor hoods.
  • the invention improves the efficiency of the odor filter Air humidity, air temperature and preferably also with regard to air pollution optimized. It has been shown that solid and dirty Particles in the extractor hood influence the efficiency of the odor filter and that through their filtration, the efficiency is significantly improved can be.
  • the odor filter preferably contains as a material for odor removal Activated carbon and / or zeloith. Both are known from the prior art. These odor filters are so-called adsorption filters.
  • the invention has the following advantages in particular: improved efficiency odor elimination, an extended service life of the odor filter, thereby reduced operating costs, condensation of water vapor through the heat exchanger at a predetermined location and thereby simply collect condensed water and there are no special ones structural measures to install the improved extractor hood required.
  • 1, 2 and 3 of the drawings show an extractor device according to the invention in the form of an extractor hood for recirculation mode.
  • she contains an extractor air duct 3 for air circulation A-A1 from and to the Range hood surrounding room, usually a kitchen, being the extractor airway 3 generates at least one first blower 2 a circulating air flow A-A1 and an odor filter 4 contains.
  • a cooling air path 5 for cooling air B-B1 is provided, which at least contains a second fan 6 for generating a cooling air flow B-B1.
  • A-A1 and B-B1 are provided between the two airways 3 and 5 .
  • the odor filter 4 is in the extractor airway 3 arranged downstream of the heat exchanger 8.
  • a particle filter or grease filter 10 is in the extractor airway 3 of the air flow A-A1 arranged upstream of the heat exchanger 8 and forms one Inlet for air circulation A-A1.
  • the upstream beginning of the cooling air path has one from the surrounding room 12 room air as cooling air B sucking cooling air inlet 14.
  • the downstream end of this cooling air path 5 also has a cooling air outlet 16 opening into this surrounding space 12.
  • the fat filter 10 is preferably a so-called eddy current filter. He is constructed so that air flowing through it swirls is initiated.
  • the grease filter is used to remove solid and liquid particles in the air circulation A-A1.
  • the degree of particle separation can be around 90%.
  • the grease filter 10 has in the extractor hood an inclined position obliquely downwards to the rear. This can cause fluid, which collects in the grease filter 10, drain backwards downwards and in one collecting container 16 arranged at the rear end of the grease filter 10 to be collected.
  • a plate heat exchanger 8 is shown as an example, but others are also Types, for example tubular heat exchangers, can be used. Steam and other portions of the airflow A-A1 that have a low boiling point have condensed on the colder heat exchange walls of the Heat exchanger 8. The condensate drips from the heat exchanger 8 in the grease filter 10 and flows backwards into the collecting container 16. Part of the condensate can be transferred from the heat exchanger 8 directly to the bottom drop 2 arranged in it drip. The air flow A-A1 is in the heat exchanger 8 cooled because the cooling air flow B-B1 of the surrounding Room 12 has a lower temperature than the dirty or steam-containing air A from a hotplate located under the extractor hood.
  • the heat exchanger 8 ensures that condensation processes take place at a certain point in the extractor hood, d. H. just on the heat exchanger 8. This causes undesirable condensation processes e.g. B. in housings and other air conduction points prevented.
  • the odor filter 4 contains A-A1 to remove odors from the air flow Activated carbon or zeolite or other material.
  • the second fan 2 is in the recirculation air flow A-A1 between the heat exchanger device 8 and the odor filter 4.
  • the odor filter 4 downstream of the first fan 2 becomes the sound pressure level and thus the noise of the extractor hood reduced.
  • the first fan 2 and the clean air outlet 20 and the odor filter 4 are located above the heat exchanger 8.
  • the grease filter 4 is located below the heat exchanger 8.
  • the second fan 6, e.g. B. a cross-flow fan, serves to ventilate the Heat exchanger 8.
  • the air from the surrounding space 12 is used for this.
  • the cooling air is sucked in through a grille at the cooling air inlet 14 the heat exchanger 8 moves, and then passes through with a grid provided cooling air outlet 16 in the surrounding space 12 again.
  • the first fan 2, the odor filter 4 and the clean air outlet 20 are located itself in a horizontal plane and the second fan 6 and the cooling air outlet 16 are in another level above the Extractor hood.
  • the cooling air inlet 14 is located at a distance below these two levels, but above the grease filter 10.
  • the second blower 6 is arranged in the rear hood area and through an outflow duct 22 with the cooling air outlet arranged on the front side 16 connected.
  • the outflow channel 22 is preferably sound-absorbing Material 24 lined.
  • the heat exchanger 8 is preferably a structural unit, which without disassembly parts of the extractor hood are easily removable and is easy to use in it.
  • Fig. 2 shows the heat exchanger 8 in inserted position in solid lines and in removed Position 8 'in dashed lines, the direction of removal by a Arrow 26 is indicated.
  • the heat exchanger 8 can itself be a front part of the extractor hood form or be arranged behind a cover 28 which is used to open the Extractor hood either easily removable, e.g. B. attachable, or like one Door can be pivoted.
  • the condensate collection container 16 can under the rear of the Heat exchanger 8 may be arranged so that 8 condensate from the heat exchanger can drip into it.
  • the grease filter 4 preferably extends over its entire length, but at least over the length over which it is below the heat exchanger 8 is arranged obliquely from the top to the rear below. It can protrude forward over the heat exchanger 8, like this 1 and 2 is shown as an example.
  • FIG. 4 shows several variants of the invention. The same parts as in FIG. 1 to 3 are provided with the same reference numbers.
  • Variant 1 From the first fan 2, an exhaust outlet connection 32 follows above, which can be connected to an exhaust air duct leading into the outside atmosphere of the building in which room 12 is located. Thereby instead of the recirculated air flow A-A1, an exhaust air flow A-A2 results for steam-containing Air A, which in turn through the grease filter 4, then through the Heat exchanger 8, then through the odor filter 4-2 and then as cleaned exhaust air A2 is led into the outside atmosphere.
  • Variant 2 By a combination of the embodiments according to FIG. 1 to 3 and Fig. 4, an extractor hood is possible, which by flap flaps 34 and 36 optionally for air recirculation with one Recirculation air flow A-A1 or switchable for exhaust air operation with an exhaust air flow A-A2 is.
  • Variant 3 Instead of the cooling air flow recirculating through room 12 B-B1 can, according to FIG. 4, a cooling air path with a cooling air flow B-B2 are used, in which the cooling air B is removed from the room 12 in which the extractor hood is located, and then is not returned to space 12, but downstream of the second Blower 6 emitted to the outside atmosphere via a cooling air outlet 38 which surrounds the building in which room 12 is located.
  • the cooling air can be selected by adjustable flow flaps 40, 42 as recirculated air B-B1 or as exhaust air flow B-B2.
  • the cooling air B in to emit the outside atmosphere as exhaust air B2 instead of into room 12 recirculate, especially on hot summer days for kitchen air conditioning be desired.
  • Variant 4 instead of taking the cooling air B from room 12, it can be used for Air conditioning of room 12 may be desirable on hot summer days,
  • To take cooling air C from the outside atmosphere that surrounds the building, in which space 12 is located, as through a cooling air inlet 44 for outside air in Fig. 4 is shown schematically.
  • This cooling air C the Outside atmosphere can flow through the heat exchanger 8 and of the second blower 6 through the cooling air outlet 16 as heated cooling air C1 in room 12 or, according to another embodiment, through the Outside atmosphere outlet 38 of the second fan 6 as heated cooling air C2 can be led into the outside atmosphere, which is achieved by switching from Flow flaps 40, 42, 46 and 48 are alternatively possible.
