Definitions
- the invention relates to a method for cleaning Extractor hoods, with a rotating one spraying device in the interior of the extractor hoods Cleaning water is sprayed and the cleaning water withdrawn from a sump on the floor of the interior becomes.
- the invention also relates to a device to carry out the method, with one in the interior an extractor hood arranged rotatable Spray device and with one on the floor of the interior the extractor hood arranged sump for Cleaning water.
- Such extractor hoods are used in kitchens deduct the resulting haze.
- At the lower end of the impact separator is usually a collecting trough arranged that the descending Condensate is collected and discharged.
- the object of the invention is a method of the beginning to create the genus with which an essential Simplify and facilitate the cleaning process of the entire interior of an extractor hood becomes.
- This object is achieved in that the entire interior of the extractor hood at intervals by means of the rotatable spray device essentially is completely sprayed with cleaning water.
- Impact separator is provided that the back wall the impact separator is sprayed with cleaning water.
- An inventive device for performing the This is a procedure with an extractor hood characterized that the spray device for Cleaning water as a spray lance with several, in Distributed lengthways and circumferentially Spray nozzles is designed to be rotatable about its longitudinal axis stored and connected to a rotary drive.
- the spray lance is preferably essentially parallel and at a distance from the rear of an impact separator arranged. This is done in a constructively simple manner a spraying device that realizes the whole Interior of the extractor hood sprayed, the of the spray jets exerted on the spray head Reactive forces at the same time to drive the spray head serve. The need for a separate rotary drive for the spray head. In addition, only one very small number of spray nozzles required.
- the extractor hood shown in FIG. 1 has a housing 1 on, in the sloping front wall 2, a window recessed is in which a baffle separator 3 is used removably is.
- a blower 4 which is only schematically indicated in FIG. 1, sucks through the impact separator 3 into the interior 5 the extractor hood 1 from entering haze.
- 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 interlock with one another in this way, that each U-profile rod 6 of a grid 3a each with two adjacent U-shaped bars 7 of the other grid 3b is nested.
- Fig. 2 with dash-dotted lines is indicated, arises for the air laden with condensate is a meandering flow path with repeated complete redirection. That in the air The condensate contained hits the surfaces of the U-profile bars 6 and 7 and mostly separates there.
- a condensate trap 8 arranged, which in the U-profile bars 6 and 7th collecting condensate and to a collection point leads.
- the two grids 3a are means Screws 9 and spacer 10 releasably together connected and removable so that they can be rinsed and so can be cleaned.
- a spray device in the interior 5 of the extractor hood arranged for cleaning water which is shown in the Embodiment has a spray lance 13 with several longitudinally and circumferentially distributed spray nozzles.
- the spray lance 13 is substantially parallel and in Distance to the rear of the impact separator 3 is arranged.
- she is in the side walls of the housing 1 about its longitudinal axis rotatably mounted and with a (not shown) Rotary drive connected and is at one end with Feeding cleaning water.
- Spray cleaning of the extractor hood is carried out in the specified manner time intervals, the length of which varies according to the seizure directed by condensate.
- the spray device has a longitudinally movable Has spray car, the spray nozzles at the Longitudinal movement of the spray trolley the inner walls of the extractor hood including the rear wall of the impact separator 3 sprinkle.
- the spray device has a longitudinally movable Has spray car, the spray nozzles at the Longitudinal movement of the spray trolley the inner walls of the extractor hood including the rear wall of the impact separator 3 sprinkle.
- such a device does not fall under the scope of the claims.
- an extractor hood its housing 1 'has a closed, to the sump 14 sloping bottom wall 16 on as well a side air inlet 17.
- a water collection channel 18 which has at least one falling drain line 19 connected to the collecting sump 14 is.
- the air inlet 17 has one above the water collection channel 18 arranged baffle 20 on for in the air inlet 17th entering spray jets of the spray device 13 '.
- the Baffle 20 is hereby deflected downwards Inner wall of the air inlet 17 is formed.
- the inlet-side bottom edge 21 of the air inlet 17 is Arranged above the water collection channel 18, so that the Bottom edge 21 dripping cleaning water into the water chamber 18 arrives.
- the entry side Bottom edge 21 of the air inlet 17 through a Round profile for example a tube, is formed.
- the air vent opening 22 is below the air inlet 17 of the extractor hood.
- the flow path of the air from the air vent 22 in the Air inlet 17 is around the rounded bottom edge 21 around deflected more than 120 °, preferably up to 180 °.
- This Deflection of the flow channel for the in the extractor hood entering air and the arrangement of the water collection channel 18 below the deflection point cause that in the Air inlet 17 entering portion of the cleaning water safely and is fully absorbed, but at the same time all interior surfaces of the extractor hood, on which Condensate can be cleaned by spraying become.
- the falling drain lines 19 are here Pipes arranged on both sides of the air collection hood 1a and on the collecting sump 14 connected.
- the spray device 13 has an axis of rotation 23, which is preferably vertical, rotatably mounted Spray head 24 on (Fig. 4), which rotates freely at the lower end a water supply line 25 is mounted.
- Spray nozzles 25 are located to the side of the rotatable spray head 24 arranged, the spray jets 26 angled in the manner are that the reaction forces they exert Apply torque around the axis of rotation 23. This will make the Spray head 24 driven to rotate.
- the spray head 24 is inclined upward directed flat jet nozzle 27 and an obliquely downward directed flat jet nozzle 28, so that during the rotary movement of the spray head 24 each point of the interior of the Extractor hood in by the rotational frequency of the spray head 24 sprayed predetermined short intervals and thus cleaned becomes.
