  • a ventilation arrangement with an extractor hood in which exhaust air filtered in the area of a separator is received via a distribution shaft in such a way that a ventilation system that is adjustable to the respective steam load is effective.
  • An additional supply line can be integrated into this hood construction in such a way that fresh air can be supplied to the extractor hood in the close vicinity of the extractor hood.
  • a generic extractor hood is known, in which, starting from a distribution shaft containing a UVC system, a return connection that detects a partial volume of the filtered and disinfected exhaust air is integrated into the multi-layer wall of the hood construction ( WO 2012/055504 A1 ), so that a compact structure with variable adjustment options is achieved.
  • the partial volume of the exhaust air irradiated and filtered with UV light in the area behind the separator can be selected can be returned from the distribution shaft or a transfer chamber to the extractor chamber.
  • a mix of fresh air is also provided in this professional hood construction.
  • EP 0 401 583 A1 shows a construction that can be used in private kitchens as a ventilation hood with only one fan.
  • an eddy nozzle on the edge is intended to improve the conveyance of the exhaust air via the blower to a passive exhaust air line.
  • the central "circulating air blower” generates the exhaust air flow, is used for horizontal pressure generation and causes eddy formation at the edges, so that overall only a small amount of exhaust air disposal is possible.
  • a similar extractor hood according to DE 10 2006 032 477 A it is designed as a cuboid housing, so that a closed filter box is provided for private cooking areas.
  • the only blower of the system interacts directly with the respective separating and filter elements on the output side, so that this blower is disadvantageously exposed to high loads and the filter performance is disadvantageously limited.
  • the invention is concerned with the problem of creating a ventilation arrangement for an extractor hood located on a central ventilation system, in which less Technical effort a module for exhaust air return, which can be used variably in large kitchens in particular, is implemented on the hood system with a low installation height, the kitchen fumes sucked into the fume intake space can be influenced in an optimal flow orientation towards the separator and also in comparison to known extractor hoods with a comparative feature low fresh air supply an overall energy saving is achieved.
  • the invention solves this problem with a ventilation arrangement with an extractor hood according to claim 1. Further advantageous embodiments result from claims 2 to 10.
  • the ventilation arrangement with an extractor hood connected to a central extraction system is provided with a return connection which, according to the invention, has at least one branch duct as a functional additional part of the system which extends outside the extractor space, which is limited in particular by the ceiling part and the longitudinal and transverse side parts.
  • This is designed as an additional module that can be variably adapted to the construction of the respective hood.
  • the design of the branch duct which can be implemented in a variable design, provides for a recirculating air system which "divides the exhaust air" to be integrated into the extractor hood.
  • a partial return of filtered exhaust air also has a targeted influence on the vapors sucked into the fume intake space in front of the separator.
  • a flow system is generated with the partial volume of the exhaust air guided via the return connection of the branch duct, with which an unwanted escape of moisture-containing haze into the surroundings of the hood can be avoided.
  • the recirculating air partial volume fed into the vapor receiving space via the branch duct and a transfer chamber can be controlled and directed in fluidic optimization in such a way that this partial volume diverted from the "heated" exhaust air only flows in the area below the extractor hood near its ceiling portion. This avoids that exhaust air gets into the surrounding space, and at the same time the rising vapor can be deflected in its direction of movement towards the separator in such a way that an air-steam mixture influenced in terms of flow technology is detected in the vapor receiving space and discharged from it.
  • This partial volume of the exhaust air is conveyed out of the transfer chamber located on one of the side parts by means of a fan, so that in the vicinity of the transfer chamber a negative pressure is effective in the vapor absorption space and the vapors rising from the surrounding space receive a delivery pulse in the direction of the separator opposite the transfer chamber ,
  • This partial system of the air and vapor line which is largely closed with a view to the air circulation circuit described above, is constructed in such a way that "only cleaned" exhaust air from the return connection can be used. This means that the previous blowing in of fresh air can be reduced to a minimum and energy can be saved.
