Definitions

• the invention relates to a device for separating or removing grease or oil-containing condensate from rooms with an oil, grease and / or water vapor old atmosphere, in particular suspended ceiling or extractor hood, with separator elements, which are in particular detachably held by means of a supporting structure and collecting elements or in Cross-section, in each case open, channel-shaped, parallel backdrops, which partially overlap each other with their open sides and have a passage for air between the backdrop edges, which catch elements or backdrops are arranged obliquely to a gutter, opening into it.
• Such devices are known for example from US-A-3 364 664 or US-A-3 566 585 as an extractor hood, particularly in kitchens.
• the separator elements provided are arranged at an angle and guide the condensate they have taken up at their lower edge into a gutter which has to be drained off occasionally and in particular cleaned. Since this may not be done regularly, this results in a very unhygienic arrangement and if the channel is overfilled, considerable contamination can occur in the cooking area, which is particularly dependent on hygiene.
• the separator elements have a cross-section that is open on one side, trough-shaped, parallel backdrops, which partially overlap with their open sides and have a passage for air between the backdrop edges, these backdrops each having a front end wall with passages for such in one Separator element have collected grease or the like.
• This one-sided end wall is placed with its lower edge on a support which is simultaneously formed in one piece as a collecting trough. A section of this support serves to put on the backdrop edges, while the main section of this support located underneath represents the gutter.
• the channels can only be cleaned in an installed, ie not very accessible, position, in which case the separator elements located on them must be removed or cleaning steam must be supplied.
• Mechanical cleaning which would also remove very encrusted dirt, which is necessary if the unpleasant regular cleaning was neglected, for example for convenience, is practically not possible unless the entire suspended ceiling or at least the gutters are removed in a complex manner.
• EP-B-0 194 527 has therefore already disclosed such a device for separating in the form of a suspended ceiling, in which the collecting channel is divided into individual channel pieces in its longitudinal direction and the channel pieces are detachably coupled to one another in the pulling and pushing directions and relative to the carrier are movable.
• This makes it possible to leave the separator elements on the carrier, but to detach the gutter and clean it thoroughly.
• This arrangement is a considerable step forward, but nevertheless still has inconveniences, so that cleaning is not carried out more frequently in these cases as well.
• the sliding guide for the gutter pieces is designed so that moving is difficult and often stiff, because on the one hand the support parts of the carrier must remain in their position, but on the other hand the gutter pieces should attack it and this despite their Subdivision over a relatively long length.
• parts of this type made from sheet metal such a precise guidance is not possible that the gutter pieces engaging with bent edges on the supports can be moved without tilting and jamming.
• the channel pieces can also show deformations due to rough treatment, which prevent the necessary smooth movement.
• the object is therefore to create a device of the type mentioned at the outset in which the removal of the condensate collected and the cleaning of the collecting trough are considerably simplified and can be carried out conveniently.
• the device mentioned at the outset is characterized in that at least one collecting container is slidably and / or removably mounted in the collecting trough, in which the separator elements or scenes open and which shields the collecting trough against the condensate emitted by the separator element or scenes .
• the gutter is kept free of condensate from the outset, so it generally does not need to be cleaned at all. It is sufficient to remove and empty the collecting container which can be moved in this collecting trough from time to time, this collecting container then being very easy to clean. This prevents the permanently installed collecting trough, which is often not easily accessible, from having to be cleaned in an uncomfortable position or even at dangerous heights. Furthermore, complex and often still difficult sliding guides between the gutter pieces and a carrier are avoided.
• the collecting trough can be permanently installed and, due to the collecting container (s) in it, will not be released at all Condensate dirty.
• the collecting trough is covered or shielded by the collecting container over its entire length or over part of its length, in which separator elements or sliding ends open. This prevents part of the condensate from getting into the gutter outside the collecting container.
• the upper free edge of the collecting container can run approximately at the level of the upper edge of the collecting trough or above. If the upper edge of the collecting tank even runs above that of the collecting channel, more condensate can be collected than the collecting channel itself could. On the other hand, however, it may be better to arrange the edge of the collecting trough higher than that of the collecting container in order to obtain a possibility in this edge region, which will be described below, of preventing condensate from entering the joint between the collecting container and collecting trough.
• the collecting container can be displaceable or removable or displaceable for removal. Above all, this latter option is to be preferred over removal by lifting it out of the gutter, because this is structurally particularly easy to implement and there would often be no space for lifting above the gutter due to the other construction elements of the entire device. However, if the entire device has a very long length, in particular in a large kitchen, it would be difficult to remove it by pulling and pushing the collecting container out of the collecting trough and to handle the correspondingly long collecting container.
• a particularly beneficial and An expedient embodiment of the invention can therefore consist in providing a plurality of continuous or aligned collecting containers with wall ends on both sides over the collecting area of the collecting channel or the entire length of the collecting channel, which in the use position meet essentially without gaps, and that these collecting containers are pulled - Coupled and thrust direction, in particular releasably connected to each other and jointly displaceable relative to the gutter, in particular can be pulled out of it and inserted again after emptying. Even a single collecting container has end walls at the end in order to be able to store the condensate in temporary storage until this collecting container is removed.
• the collecting container (s) has a cross have a sectional profile, which corresponds approximately to the cross section of the inner contour of the gutter. This results in a good guidance of the collecting container in the collecting trough, in which the risk of canting and the like need not be feared. Even in the event of slight deformations, the collecting container can lie relatively loosely in the collecting channel over the long length and can accordingly be moved slightly.
• Embodiments of the invention in particular the collecting container and its mutual releasable coupling are the subject of claims 6 to 8.
• the features and measures described therein result in structurally simple options, several collecting containers that are aligned with one another in the collecting channel and are essentially adjacent to one another in the pulling position and in the use position To connect the direction of thrust and also to ensure that the joint between two adjacent collecting containers of this type is covered so that no condensate can enter between the collecting container and the underlying gutter at this joint.
• an advantageous embodiment of the invention can consist in that the collecting trough on its upper longitudinal edge, which engages under the separator elements, parallel to which the collecting container (s) can be displaced, in particular a U - Or has a V-shaped bend, which is directed towards the center of the gutter and whose upper leg in the use position covers and shields the upper longitudinal edge of the collecting container (s) and is inclined downwards from the outside towards the horizontal towards the inside of the collecting gutter.
• This has the considerable advantage that condensate that may drip from a separator element, for example from its underside, does not fall between the collecting container and Can enter gutter, but is guided from the upper leg of the bend into the interior of the collecting container.
• the upper edge of the end walls can be arranged lower than the encompassed and shielded longitudinal edge of the collecting container or it can be between the end wall and channel wall a slot taking into account the upper leg of the U-shaped or V-shaped bend and receiving in the region of the end walls.
• This slitting can be avoided if the collecting trough has a raised longitudinal edge running obliquely upwards and outwards with the corresponding bend and thus there is sufficient internal volume in the collecting containers, even if the end walls do not protrude into the region of the bends.
• At least one Abseheiderelernent itself or by means of a projection arranged on it engages from above so deeply into at least one, in particular the rearmost, when pulling out of the collecting trough that it overlaps at least one end wall against the sliding direction required for removal.
• the separator elements which open directly into the collecting trough or the collecting container, also frequently have to be cleaned, and if the user has to remove the separating elements first in order to release the blocking of the collecting container, he has already carried out the essential activity to clean them to cause these separator elements, for example, to insert the removed separator elements into a dishwasher.
• the "unlocking" of the collecting container expediently requires the loosening of all separator elements leading to the collecting container.
• the collecting trough and / or the collecting container located therein for emptying can have a mirror-symmetrical profile with respect to a vertical longitudinal center plane, which is an arrangement which is particularly well suited for suspended ceilings in which separator elements with their backdrops or the like are inserted into them from both sides Collecting gutter and the collecting container open.
• extractor hoods it is also possible, in particular for extractor hoods, to provide a half-gutter with a correspondingly profiled collecting container, in which the gutter wall overlapped by the separator is arranged with its cross-section obliquely and the cross-section of the other, in particular on a holder or similar gutter wall, is arranged vertically or almost vertically is.
• separator elements open into the one or only from one side Collecting container he and the rest of a fume hood can be provided, which has an approximately vertical termination, on the lower edge of which the above-described collecting trough with collecting container is then arranged.
• the stationary gutter has a latch, lock or a lock at the end at which the receptacles are removed when it is pushed out, with which an unauthorized removal can be prevented, so that, for example, the actual user of the kitchen or the like does not even notice or knows that the bins are not in place.
• this can ensure that when the collecting container is inserted into the collecting channel, it is really pushed in completely because otherwise it cannot be locked, closed or locked.
• a further embodiment of the invention can consist in that the side walls projecting directly beyond the end walls of the collecting containers overlap in the coupling region, so that no gap, however small, remains free outside the region of the end walls.
• the side wall of the collecting container which overlaps the adjacent end wall of the next collecting container with an approximately U-shaped bend in its front wall, engages on the inside over the side wall of this adjacent collecting container. This results in an approximately tile-like arrangement in this overlap area, which prevents that above the couplings on the side walls Condensate enters between the collecting tanks.
• the overlap is so large that it also corresponds to that in the area of the end walls.
• the overlapping wall area can be formed by a projection of the side wall, which extends from the upper free longitudinal edge to about the front wall or below the front wall and protrudes from the front wall in the sliding direction by about the amount by which the V-shaped or U-shaped bend of the coupling protrudes from the front wall.
• the embossing of the side wall to the outside can be arranged at the opposite end of the collecting container and can have a greater width in the longitudinal direction than the overlap area, so that the frontal projection fits with certainty in the embossing area of the side wall of the adjacent collecting container.

• a device generally designated 1, particularly in FIGS. 2, 4 and 5, serves for separating or removing condensate containing grease or oil from rooms 2 - see FIG. 1 - with oil, grease and / or atmosphere containing water vapor, such as exists in canteen kitchens.
• Fig.l shows that the device 1 can be a false ceiling, which is made effective above the stove area by appropriate inclination of the separator elements 3 to be described, these parts arranged above the stove area can also be provided or designed as extractor hoods.
• the already mentioned separator elements 3 are held releasably according to FIGS. 2 and 4 by means of a supporting structure 4 and each have one-sided open, channel-shaped, parallel scenes 5, which partially overlap with their open sides and have a passage for air between the scenery edges.
• These backdrops 5 are combined to form cassettes as separator elements 3 which, according to FIG. 1, can be removed individually from their holders in order, for example, to clean them in a dishwasher.
• the sloping scenes 5 lead to the condensation of oil, fat and moisture from the air passed through them and ensure by means of their inclination, which may also have a smaller gradient than in Fig.4, that this condensate is directed to a gutter 6 , in which these scenes 5 open according to Fig.4 and 5.
• a collecting container 7 is arranged in the collecting trough 6, which is displaceable in the direction of the arrow Pfl out of the collecting trough 6 so that it can be removed.
• This collecting container 7 shields the collecting channel 6 against the condensate given off by the separator elements 3 and 5, so that the collecting channel 6 is not wetted and contaminated with this condensate and thus this permanently installed collecting channel 6 does not have to be cleaned. Rather, the cleaning can be carried out in a simple and convenient manner in that from time to time the collecting container 7 is pulled out in the direction of the arrow Pfl, emptied and cleaned and pushed back again. Since this collecting container 7 is located in the collecting channel 6, the separator elements 3 and their backdrops 5 open into this collecting container 7.
• the collecting trough 6 is covered and shielded by the collecting container 7 over its entire length and thus over the part in which separator elements 3 or scenes 5 open.
• the upper free longitudinal edge 8 of the collecting container 7 runs approximately at the height of the upper longitudinal edge 9 of the collecting channel 6, so that the best possible use of space and the largest possible volume for the collecting container 7 is given. It can be seen that the longitudinal edge 9 of the collecting channel 6 runs slightly above the longitudinal edges 8 of the collecting container 7, because the collecting channel 6 on its upper longitudinal edge 9, which engages under the separator elements 3, parallel to which the collecting container 7 can be displaced, is approximately U.
• individual collecting container 7 can thus also be understood or referred to as a collecting container 7 having several parts.
• they will each be referred to as collecting containers 7, that is, the following description assumes that several collecting containers 7 coupled in the manner described above are provided in collecting channel 6. This has the considerable advantage that, with a relatively long length of the collecting trough 6, it is possible to remove the collecting container 7 even in a somewhat cramped space, while a length of the total length of the collecting trough 6
• Corresponding collecting container 7 would need a sufficiently large free area for its extraction.
• the collecting containers 7 have a cross-sectional profile which corresponds approximately to the cross-section of the inner contour of the collecting channel 6. Thus, they can shield the gutter 6 well and still absorb about as much condensate as the gutter 6 could also without such a collecting container 7.
• each end wall 12 of a collecting container 7 has a hook-shaped bevel 13 pointing away from this end wall 12 at its upper edge, which overlaps and engages behind the directly abutting smooth end wall 12 of the neighboring collecting container according to FIG.
• the upper edge of this smooth end wall 12 can also be deformed in a bead-like manner according to FIG. 6d in order to form an improved coupling and, above all, to facilitate the re-coupling.
• the hook-shaped formation or bevel 13 leads on the end wall 12 of the collecting container 7 without gaps over the entire end wall 12 at least in the area that receives a condensate to be separated, and this formation or bevel 13 extends with its free edge 13a over the end wall 12 and the bead 12a of the adjacent collecting container 7, this free edge 13a according to FIG. 6d being lower than the upper edge or bead 12a of the overlapped end wall 12.
• This hook-shaped bend or formation 13 thus not only forms a coupling in the pulling direction, but also bridges and covers the joint 14 between the two facing end walls 12 of the two immediately adjacent collecting containers 7, that is to say this formation or bend 13 has a double function in that it acts as a releasable coupling effective in the pulling direction, but also prevents condensate from entering between the end walls 12.
• the upper edge of the end walls 12 is arranged lower than the encompassed and shielded longitudinal edge 8 of the collecting container 7. If the upper edges of the end walls 12 were arranged in the same plane as the longitudinal edges 8, the end walls 12 themselves or between themselves and the channel side wall 17 of the collecting channel 6 would have one have upper leg 11 of the U- or V-shaped bend 10 slot. Such a slot is avoided by the different heights of the respective edges * ⁇ chosen.
• separator elements 3 Since the separator elements 3 also receive condensate deposits over the course of time, that is to say they have to be cleaned, it is advantageous if the user is "forced” to also remove the separator elements 3 from their detachable holder and to carry them out for cleaning when they collect the containers 7 emptied. In the exemplary embodiment it is therefore provided that the separator elements 3 lock the collecting container or containers 7 against displacement from the collecting channel 6 in the use position. In the present case, this is achieved in that at least one separator element 3 according to FIG.
• the collecting channel 6 and the collecting container 7 located therein which can be moved out of the collecting channel 6 for emptying and cleaning, are mirror-symmetrical to a vertical longitudinal center plane L or have a mirror-symmetrical profile.
• the device 1 is an extractor hood acted on from two sides. If, however, an extractor hood that is only accessible from one side is necessary, a collecting channel 6 that is “half” in cross section compared to FIG.
• FIG. 5 can be provided with correspondingly profiled collecting containers 7, in which the channel side wall 17 overlapped by the separator 3 and accordingly also the side wall 15 of the collecting container 7 with its cross-section obliquely and the cross-section of the other, in particular on a holder or the like arranged channel wall - is arranged vertically or almost vertically - for example in the plane L.
• the representation of FIG. 5 could also be understood as such a device 1 designed as an extractor hood if the plane L is designed as a vertical closure and only one side of a separator element 3 and a correspondingly "halved" collecting channel 6 are halved "Collection container 7 is provided.
• the stationary collecting trough 6 can have a bolt, closure or a lock at the end at which the collecting containers 7 are removed when pushed out in the direction of the arrow Pfl. This not only prevents unauthorized removal, but also ensures that all of the collecting containers 7 are properly reinserted, namely when this bolt or closure can be brought into its closed position.
• the side wall 15 of the collecting container 7 which, with an approximately U-shaped bend or bevel 13 of its end wall 12, overlaps the adjacent end wall 12 and the bead 12a provided there of the next collecting container 7, on the inside the
• FIGS. 7 and 8 and also also in FIGS. 6 and 6d it is made clear that the overlapped side wall 15 of the one collecting container 7, i.e. the collecting container 7 on the right in FIG. 6, has an embossing 20 approximately on the thickness of the side wall overlapping it 15 of the adjacent collecting container 7 located on the left in FIG. 6.
• This thickness or depth t of the impression 20 can be seen in FIG. 8. It is the amount by which the indentation 20 is deformed outward from the plane of the other side wall 15, that is, away from the interior of the collecting container 7.
• the embossing 20 of the side wall 15 to the outside is arranged at the opposite end of the collecting container 7, that is to say it is exactly opposite the overlapping wall area 19 at the opposite end and has a greater width in the longitudinal direction than the overlapping wall area 19, so that this in any case in the use position comes to lie within the embossed area of the embossing 20. This prevents mutual constraints and an unwanted frictional connection in the overlap area.
• a device 1 for separating condensate from atmospheres containing oil, grease and / or water vapor for example in canteen kitchens, in which a condensate trap 6 which does not become contaminated by this condensate in an apparently contradictory manner does not need to be cleaned.
• this gutter 6 can then be installed permanently and thus appropriately stably, in order to also be effective as a carrier in the area of a false ceiling or an extractor hood or a combination of both, that is to say can perform a double function. It is not necessary to provide a collecting trough 6 which is detachable with respect to a carrier. This is achieved in a simple manner by providing one or more collecting containers 7 lining and shielding the interior of the collecting channel 7 in this collecting channel 6, several collecting containers 7 arranged in the direction of extension of the collecting channel 6 having the advantage of being pulled out of the collecting channel 6 piece by piece To be able to be removed, so that there must not be as much space in the extension direction as it corresponds to the length of the collecting channel 6.
• a handle 21 can still be seen on the left-most collecting container 7, by means of which this collecting container 7 can be grasped when it is pulled out. This could also be attacked by a locking device (not shown in more detail) which, when all opening elements are properly inserted, catch container 7 can be brought into the use position.
• the device 1 for separating condensate containing grease, moisture or oil from rooms 2, for example canteen kitchens, can be a false ceiling, an extractor hood or a combination of both. It has known separator elements 3, which are detachably held on a supporting structure 4, for example in order to be cleaned in dishwashers. These separator elements 3 have collecting elements or baffles 5 for the condensate, which guide it through an inclined position to a collecting channel 6. In this collecting channel 6 at least one collecting container 7 or a chain of collecting containers 7 is slidably and / or removably mounted, so that the condensate discharged from the separator element 3 or its backdrops 5 reaches this collecting container 7. The permanently installed collecting channel 6 is therefore shielded from this condensate by the collecting container or containers 7. For emptying and cleaning, the collecting container or containers 7 can be pushed out of the collecting channel 6.
