Definitions

  • the invention relates to a method for cleaning extractor hoods.
  • the invention also relates to a device for performing the method.
  • Such extractor hoods are used to remove the vapor produced in cakes.
  • the impact separator For this purpose, it is known to arrange an impact separator at the air inlet into the extractor hood, in which the incoming air is deflected so strongly that the droplets of condensate contained therein strike the walls of the impact separator and are separated there.
  • the impact separator consists, for example, of several, mutually interlocking U-shaped bars, which are each arranged at a distance from one another in order to allow air to pass through.
  • a collecting trough is usually arranged, which collects and discharges the consume coming down.
  • the object of the invention is to provide a method of the type mentioned, with which a significant simplification and simplification of the cleaning process of an extractor hood is achieved.
  • This object is achieved according to the invention in that the interior of the extractor hood is sprayed with cleaning water at intervals by means of a flushing device and that the cleaning water is drawn off from a collecting sump at the bottom of the interior.
  • a device according to the invention for carrying out the method with an extractor hood is characterized in that a spray device for cleaning water is arranged in the interior of the extractor hood and that a collecting sump for cleaning water is arranged on the bottom of the interior of the extractor hood.
  • the spray device preferably has a spray head rotatably mounted about an axis of rotation with spray nozzles, the spray jets of which exert a torque about the axis of rotation on the spray head.
  • a spraying device is realized which sprays the entire interior of the extractor hood, the reaction forces exerted by the spraying jets on the spraying head also serving to drive the spraying head. This eliminates the need for a separate rotary drive for the spray head; in addition, only a very small number of spray nozzles are required.
  • the spray device has a spray lance with a plurality of spray nozzles distributed in the longitudinal direction and in the circumferential direction.
  • the extractor hood has a closed bottom wall falling to the collecting sump and a side air inlet, and that a water collecting duct is arranged below the air outlet.
  • the water collection channel collects the cleaning water from the spray jets, which enters the air inlet from the interior of the extractor hood. This ensures in a structurally particularly simple and space-saving manner that no cleaning water drips down from the extractor hood.
  • the spray device has a spray lance with a plurality of spray nozzles distributed in the longitudinal direction and in the longitudinal direction, so that the entire interior of the extractor hood including the rear side of the impact separator can be sprayed and cleaned with cleaning water.
  • FIG. 3 in a greatly simplified representation, a vertical section through an extractor hood of another embodiment
  • the extractor hood shown in Fig. 1 has a housing 1, in the oblique front wall 2, a window recessed 00/56202 - 5 -
  • baffle separator 3 is used removably
  • a blower 4 which is only indicated schematically in FIG. 1, sucks off the haze entering the interior 5 of the extractor hood 1 through the impact separator 3.
  • the impact separator 3 shown in detail in Fig. 2 consists of two grids 3a and 3b of U-shaped bars 6 and 7, which are directed towards each other with their openings.
  • the U-profile bars 6 and 7 engage with one another at a distance such that each U-profile bar 6 of the one grid 3a is interleaved with two adjacent U-profile bars 7 of the other grid 3b.
  • this creates a meandering flow path with repeated complete deflection for the air that passes through and is laden with condensate.
  • the condensate contained in the air strikes the surfaces of the U-shaped bars 6 and 7 and separates there for the most part.
  • a condensate collecting channel 8 is arranged, which collects the condensate flowing down the U-shaped bars 6 and 7 and leads to a collecting point.
  • the two grids 3a are detachably connected to one another by means of screws 9 and spacer bolts 10 and can be removed so that they can be spooled and thus cleaned.
  • the U-profile bar 6 of the grid 3a and / or the U-profile bar 7 of the grid 3b are connected to one another by one or more transverse strips 11 or 12 on the rear side of the U-profile bar 6 or 7 in order to secure the grid 3a or 3b to give cohesion.
  • a spray device for cleaning water which, in the exemplary embodiment shown, has a spray lance 13 with a plurality of spray nozzles distributed in the longitudinal direction and in the circumferential direction.
  • the spray lance 13 is arranged essentially parallel and at a distance from the rear side of the impact separator 3. It is mounted on the rare walls of the housing 1 so as to be rotatable about its longitudinal axis and connected to a rotary drive (not shown) and is fed with cleaning water at one end.
  • the extractor hood is spray-cleaned at predetermined intervals, the length of which depends on the accumulation of condensate.
  • the impact separator 3 can be additionally cleaned in the manner described, the two grids 3a and 3b being taken apart and wound after the screws 9 have been loosened.
  • the spraying device has a slowly movable spray carriage, the spray nozzles of which the longitudinal walls of the spray carriage remove the inner walls of the extractor hoods.
  • 17 is a water collecting channel 18 which is connected to the collecting sump 14 via at least one falling drain line 19.
  • the air inlet 17 has one above the water collection channel
  • baffle 20 arranged baffle 20 on for spray jets of the spray device 13 'entering the air inlet 17.
  • the baffle 20 is formed by the inner wall of the air inlet 17 which is deflected downwards.
  • the inlet-side bottom edge 21 of the air inlet 17 is arranged above the water collection channel 18 so that the cleaning water dripping from the bottom edge 21 reaches the water chamber channel 18.
  • the inlet-side bottom edge 21 of the air inlet 17 is formed by a round profile, for example a tube.
  • the underside 16a of the sloping bottom wall 16 forms the ceiling of an air collection hood la, the air extraction opening 22 of which lies below the air inlet 17 of the extractor hood.
  • the flow path of the air from the air vent 22 into the air inlet 17 is deflected around the rounded bottom edge 21 by more than 120 °, preferably up to 180 °.
  • This Deflection of the flow channel for the air entering the extractor hood and the arrangement of the water collection channel 18 below the deflection point mean that the portion of the cleaning water entering the air inlet 17 is collected safely and completely, but at the same time all the inner surfaces of the extractor hood, to which condensate can be found can be cleaned by spraying.
  • the falling drain lines 19 are arranged as tubes on both sides of the air collecting hood la and connected to the collecting sump 14.
  • the spray device 13 has a spray head 24 which is rotatably mounted about an axis of rotation 23, which preferably runs vertically (FIG. 4) and is freely rotatably mounted on the lower end of a water supply line 25.
  • Spray nozzles 25 are arranged to the side of the rotating spray head 24, the spray jets 26 of which are angled in such a way that the reaction forces exerted by them exert a torque about the axis of rotation 23. As a result, the spray head 24 is driven to rotate.
  • the spray head 24 has an obliquely upwardly directed flat jet nozzle 27 and an obliquely downwardly directed flat jet nozzle 28, so that when the spray head 24 rotates, each point of the interior of the extractor hood is sprayed and thus cleaned in short intervals predetermined by the rotational frequency of the spray head 24 becomes.
