Definitions

  • the invention relates to a vapor filter device for hobs, in particular for sucking and filtering cooking fumes below the cooking surface level.
  • hoods which are located above stoves and hobs.
  • Hoods at head height should be designed so that they do not get in the way of the user when cooking. But the greater the distance from the hob, the greater the risk of unwanted, partial distribution of cooking fumes in the kitchen.
  • extractor devices have also been used, in which cooking fumes are extracted as close as possible to the place of origin, d. H. between, beside, behind or directly above a hob. They can be stationary or extendable integrated into the hob.
  • a device for the withdrawal of cooking fumes in a vertically located below the cooking field level exhaust duct is proposed.
  • a fan motor of the trigger device can be arranged outside of a, the hob comprehensive, kitchen furniture, z. B. in the basement of a house.
  • An inlet opening of the extraction device is by means of a rotary valve or a lid ( DE 20 2009008286 U1 ) designed lockable.
  • each hob can also be assigned facilities for supplying air as flushing medium.
  • the trough-shaped inlet and closing unit can be designed removable and dishwasher suitable.
  • table fans for example according to EP 2653787 A2 known, respectively vertically from the worktop resp. Cooking field level are extendable.
  • a filter element is provided in the table fan.
  • extractor devices which can be actuated in the exhaust or recirculation mode.
  • air in a room can be sucked into an extractor unit in the exhaust air mode.
  • the air can also be decoupled from the exhaust system in recirculation mode and placed in a filter box with several filters, eg. B. Activated carbon filter to be routed.
  • the air is cleaned in these filters in several stages and enters the filter box cleanly in the room.
  • a trigger device which has a arranged in the hob exhaust opening for cooking fumes.
  • a suction duct in which a water filter is arranged to separate fat particles from the extracted, enriched with cooking fumes air.
  • a perforated plate is arranged in the water filter, is passed through the bubbling air into the water filter.
  • the air bubbles are used to transport fat particles and other particles to the water surface and form a greasy film. This greasy film should drain into a separate collection container and can be removed from there.
  • a conventional metal-knit grease filter may be arranged, but this requires additional measures for odor suppression.
  • the invention has for its object to develop a vapor filter device for hobs, in particular for sucking and filtering cooking fumes below the cooking surface level, which allows efficient removal of cooking fumes and easy cleaning of grease filters.
  • the haze filter device comprises at least one closable inlet opening for cooking fume in the cooking field level, which is associated spatially close to a hob and which communicates with an air conveying unit.
  • the inlet opening opens into a cleaning container, in which a, from the cooking fume Oberströmbare Fettabscheideiki is arranged.
  • the cleaning container also has a, preferably closable, discharge port for degreased air to the air conveyor unit and in its bottom area an outlet for separated grease and a cleaning liquid.
  • an efficient extraction of cooking fumes and a separation of fat, among other things from the cooking fumes is achieved, in conjunction with a simple, maintenance-free cleaning of the grease filter used.
  • An essential advantage of the invention is that the cleaning of the filter of the vapor filter device is maintenance-free to the extent that handling (removal and re-insertion) of the filter for its cleaning is not necessary.
  • the filter is cleaned in the haze filter device by means of an integrated cleaning module from settled grease.
  • the inventive haze filter device can be arranged in particular below the cooking surface level, but can also be arranged in head or table hoods.
  • the Fig. 1 shows a vapor filter device according to the invention, which is associated with a hob 2 of a kitchen cabinet 1, in a sectional view.
  • the hob 2 spatially close an inlet opening 3 is assigned in the cooking field level, can be sucked by the cooking fume and room air 4 (arrow) directly on the hob 2.
  • a plurality of inlet openings 3 may be arranged.
  • the inlet opening 3 can be closed watertight by means of a closure flap 5.
  • the shutter 5 may be rotatable or pivotable, as in the Fig. 1 exemplified, or as a reversibly attachable lid (not shown) may be formed.
  • a cleaning container 6 is arranged fixed or removable in the kitchen 1.
  • the inlet opening 3 opens directly into the cleaning container 6, but if necessary, a transition piece can be arranged between the inlet opening 3 and the cleaning container 6.
  • the cleaning container 6 is preferably approximately perpendicular to the air stream 4 (cooking vapor and air) a Fettabscheideerne 7, for example in the form of a sheet metal knitted fabric filter or a centrifugal, fixed or removable arranged, which is flowed through by the air stream 4. Fat particles u. a. are thereby deposited on the Fettabscheideech 7 and the fat u. a. Exempted air stream 4 leaves the cleaning container 6 through an outlet opening 8 below the Fettabscheidevenez 7. The outlet opening 8 is in turn watertight closable by means of a flap 9.
  • the flap 9 can be actuated and controlled electromechanically, for example.
  • the air delivery unit 10 comprises an air delivery channel 11 to a fan 12 with electric drive motor and at least one exhaust port 13 for the purified air stream 4.
  • the exhaust port 13 may be a unit for further air purification, for example by means of plasma or UV treatment, in particular for odor improvement ,
  • the cleaned exhaust air can be returned in a recirculation mode in the room or supplied in the exhaust air operation of the ambient air.
  • the cleaning container 6 is still a liquid module 20 ( Fig. 1 ).
  • a grease-dissolving cleaning liquid 21 is provided in this liquid module 20, a grease-dissolving cleaning liquid 21 is provided. This can be reprocessed after use.
  • the liquid module 20 is connected via supply line 23 with the cleaning container 6.
  • the supply line 23 is guided through an opening in the cleaning container 6 to at least one injection point 29, which is arranged above and / or below the Fettabscheideappel 7.
  • a plurality of injection points are arranged above and below the Fettabscheidetechnik 7 and directed to this.
  • the cleaning liquid 21 may be a specific cleaning agent. Preferably, it is tap water and while the liquid container 21 may be connected in a manner not shown to a water connection.
  • the liquid module 20 further comprises a heater 24, which is connected upstream of a pump 25, and an addition unit 26.
  • the cleaning liquid 21 is conveyed by means of the pump 25 in the supply line 23 to a heater 24, there to an optimum effective temperature for fat solution heated and sprayed on preferably several injection points 29 on the Fettabscheideischen 7.
  • the cleaning liquid 21 may be added by the addition unit 26 also another detergent.
  • the cleaning of the grease separating unit 7 preferably takes place with the inlet opening 3 closed.
  • the greasy cleaning liquid 21 collects in the bottom region 30, which is located below the outlet opening 8 of the cleaning tank 6 and is returned from there by a return line 28 and a filter 27 in the liquid container 22, in particular pumped.
  • the grease could also drip from the grease-separating unit 7 without the above-described cleaning into the bottom area 30 and be removed there.
  • the liquid module 20 may also be configured as an exchange module and, including the cleaning liquid 21, be processed by a service operation (recycling).
  • the supply line 23 may alternatively be connected directly to a dishwasher or the like, which performs the function of the liquid module 20.
  • fatty cleaning fluid 21 can also be fed directly to a, not shown, removable collecting container and disposed of in an environmentally sound manner.
  • the grease filter of the grease separating unit 7 does not need to be externally washed out. Rather, this takes place in the installed state in the cleaning container 6 and the previously usual maintenance costs are eliminated.
  • the cleaning of the flat fat filter of the Fettabscheideiki 7 takes place at the closed opening 8.
  • the cleaning can be made, for example, at fixed intervals or sensor monitored at a defined fat loading on the grease filter.
  • a drum-shaped, rotatable grease filter 40 of the Fettabscheideech 7 is provided in the cleaning container 6 instead of the flat metal-knit grease filter, which, in rotation, each lower portion 41 immersed in a bath of cleaning fluid 21.
  • the adhering fat is washed out and returned with the loaded cleaning liquid 21 via the return line 28 as described above.
  • the defatted air stream 4 is passed through a hollow and perforated shaft 42 (with an outlet opening) of the drum-shaped grease filter to the outside, analogous to the exhaust port 13th
  • the rotatable grease filter 40 may fail during operation, i. H. be continuously moistened by the cleaning fluid 21 during the Fettabscheide- and cleaning process. This moisture film on the surface of the grease filter 40 can improve the deposition of the fat molecules.
