Abstract
A device (1) for separating fatty, moisture-laden or oily condensate from rooms (2), for instance canteens, may be an underceiling, a hood or a combination of both. The device has known separator elements (3) which are held in a detachable condition by a supporting structure (4) in order that they can be cleaned in dishwashers, for instance. These separator elements (3) have collecting elements or coulisses (5) for the condensate, inclined so as to conduct the condensate to a gully (6). At least one collecting vessel (7) or a chain of collecting vessels (7) is slidably and/or removably located in this gully (6), so that the condensate supplied by the separator element (3) or its coulisses (5) reaches this collecting vessel (7). The permanently installed gully (6) is therefore protected from this condensate by the collecting vessel(s) (7). Far emptying and cleaning the collecting vessels (7) they can be slid out of the gully (6). (Fig. 2)
Description
, r ~ .
A Device for Separating Condensate with Separator Elements The invention relates to a device for separating or removing fatty or oily condensate from rooms having a oily, fatty and/or steamy atmosphere, particularly an underceiling or O hood, including separator elements which are held, particularly in a detachable condition, by a supporting structure and have collecting elements or parallel coulisses which, viewed in cross section, are channel-shaped and open on one side, said collecting elements or coulisses having their open sides in partly overlapping relationship, having a passage for air between their edges and being arranged slantwise to, and ending in, a gully.
~evices of this character are known, by way of example, from 2G US-A-3 364 664 or from US-A-3 566 585, in the form of a hood, particularly in kitchens. The separator elements proposed in these references are arranged slantwise and the condensate they hold is conducted at their lower edge to a gully. The gully has to be drained from time to time and in particular it has to be cleaned. Since it is possible that this is not attended to regularly, the arrangement is thus highly unhygienic. Any overfill of the gully may cause considerable contamination in the cooking area posing stringent demands on hygiene.
3û
A device of such a kind, in the form of an underceiling, is known from DE-A-3 145 548. The separator elements in that reference have, viewed in cross section, channel-shaped, parallel coulisses open on one side. The coulisses have their J~ ~en sides in partly overlapping relationship and have a passage for air between their edges. Each of these coulisses has an end wall with passages therethrough for the fat or the like collected in such a separator element. The lower edge of this wall at one end is placed on a carrier simultaneously forming an integral gully. One portion of this carrier serves for supporting the edges of the coulisses and the underlying main portion of this carrier constitutes the gully.
As with above-mentioned hoods, the gullys in the present instance can be cleaned only in an installed, hence not readily accessible, position. The separator elements on the gullys have to be removed or steam has to be supplied for cleaning. Mechanical cleaning would also remove caked dirt, as becomes necessary if unpleasant, regular cleaning is not carried out, for reason of convenience for instance. However mechanical cleaning is not possible in practice unless the entire underceiling or at least the gullys are dismantled in a laborious fashion.
~G Therefore EP-B-O ;94 527 has disclosed such a separator in the form of an underceiling in which the gully is longitudinally divided into separate gully pieces. The gully pieces are detachably coupled together in the direction of push and pull and are slidable relative to the carrier. By this means it is possible to leave the separator elements on the carrier, but to remove and thoroughly clean the gully.
This arrangement represents a considerable step forward but still involves inconvenience, meaning that here again cleaning is often neglected. Thus, the design of the slideway ~O for the gully pieces is such that sliding movement is difficult and often stiff. This is so, because on the one hand the supporting members of the carriers have to remain in position, but on the other hand the gully pieces are to be in engagement therewith over a relatively great length, despite ~eing subdivided. When such parts are made of sheet metal, accurate guidance is not possible in such a way as to permit that the gully pieces engaging the carriers with folded back edges be slid without tilting and jamming. Above all, after repeated use the gully pieces may be deformed through rough treatment, preventing the necessary, smooth movement.
A device of the generic kind in the form of a hood is known from DE-A-27 37 386 and from US-A-38 34 135. The separator element is in each case set at an angle so that the channel-shaped, parallel coulisses open on one side have their open sides ending in a collecting gully or trough receiving the condensate and fat formed. This collecting gully or trough is somewhat inclined and at its lowest end has an outlet through which the fat or condensate is to be drained off. It is inavoidable that deposits of fat form within the trough or collecting gully.
The draining fat reaches a further collecting gully which extends underneath the first collecting gully and can be removed for being emptied and cleaned.
The arrangement and position of the first collecting gully mean, however, that it is hard to reach and therefore can hardly be cleaned. Hence the same drawbacks present themselves as are already known from the above-described devices. In addition, this arrangement could not be realized in the form of underceilings, because the gullys lying one upon the other would need excessive height within such an underceiling.
Therefore the object underlying the invention is to provide a device of the kind mentioned at the outset, 23422-1~6 enabling the collected condensate to be removed and the gully to be cleaned in a considerably simpler and more convenient fashion.
To accomplish this object, the device mentioned at the outset is characterized in that located in a slidable and/or removal condition in the gully there is at least one collecting vessel in which the separator elements or coulisses end, and said collecting vessel protects the gully from the condensate delivered by the separator element(s) or coulisses.
In this way the gully is kept free from condensate from the outset and hence, as a rule, does not need to be cleaned at all. It is sufficient if from time to time the collecting vessels slidable in this gully be removed and emptied and whilst doing so they can be very easily cleaned.
The permanently installed gully, which is often hard to reach, therefore does not have to be cleaned in an inconvenient position or even at dangerous height.
Furthermore, elaborate and nevertheless often stiff slideways between gully pieces and a carrier are avoided. The gully can be permanently installed and is not fouled at all by the condensate due to the collecting vessel(s) in it.
It is especially advantageous if the collecting vessel covers or protects the gully throughout the gully length or through that part of the gully length in which separator elements or coulisses end. By this means it is avoided that some of the collected condensate gets~ into the gully outside the collecting vessel.
To enable condensate to be collected in the maximum quantity permitted by the inside volume of the gully, the upper free edge of the collecting vessel may run approximately level with, or above, the upper edge of the gully. If the upper 1û edge of the collecting vessel runs above that of the gully, more condensate can be collected than the gully itself could.
On the other hand, it may be preferable to arrange the edge of the gully higher than that of the collecting vessel. Then in this edge area the below-described possibility is attained ,~ of preventing condensate from entering the gap between collecting vessel and gully.
Mention was already made that the collecting vessel may be slidable or removable, or slidable for removal. The latter possibility is preferable to lifting the collecting vessel for removal from the gully. This is so, because it is structurally especially simple to realize and because the other structural elements of ~he device as a whole signify that there would often be no space at all above the gully for 2J lifting. If now, the entire device is very long, particularly in a canteen, the collecting vessel of respective length would be difficult to remove by drawing and sliding it out of the gully and to handle. An especially advantageous and suitable development of the invention may therefore consist ~u in that a plurality of collecting vessels in mutual extension of, and in alignment with, one another are provided over the collecting area of the gully or throughout the length of the gully and are closed by walls at either end. In the position of use these collecting vessels abut without any appreciable ~'J gap. These collecting vessels are coupled in the direction of push and pull, in particular they are detachably interconnected and slidable together relative to the gully.
In particular, they are adapted to be drawn out of the gully and slid back into the gully after having been emptied. Even a single colleGting vessel has end walls for intermediate storage of the collected condensate until this collecting vessel is removed. The problem of great length is expediently solved by arranging a plurality of collecting vessels one behind the other. These collecting vessels are coupled ,u together in such a way that that as the foremost vessel is drawn out, the following vessels are drawn along. Therefore, after the vessel foremost in the direction of removal has been removed, the next collecting vessel is immediately ready-to-hand and can be drawn out further, thereby drawing 1~ the next collecting vessel into the position for removal etc.
Subdividing the collecting vessel into a plurality of collecting vessels advantageously enables them to be of a size which is easy to handle and clean. Therefore not only emptying but, whilst doing so, cleaning is facilitated. By way of example, the collecting vessels may be of a size permitting them to be cleaned very conveniently in dishwashers or rinsers. Due to the short length of the individual collecting vessels, they are simply and conveniently removed and put back again.

It is advantageous if the collecting vessel(s) have a cross-sectional profile corresponding approximately to the cross section of the internal contour of the gully, automatically resulting in good guidance of the collecting vessel in the JU gully, without any risk of tilting and the like. Even if slightly deformed, the collecting vessel - as considered over the entire length - can lie relatively loosely in the gully and be slid with corresponding ease.
:
Claims 6 to 8 recite developments of the invention, particularly of the collecting vessels and the way in which they are detachably coupled together. The features and measures recited in these claims provide structurally simple possibilities for a plurality of collecting vessels, aligned in the gully and substantially contiguous in the position of use, to be connected in the direction of push and pull. At the same time assurance is provided that the ~oint between two such ad~acent collecting vessels is covered, preventing ,u any condensate there from getting in between the collecting vessels and entering the underlying gully.
In connection with the arrangement of the longitudinal edges of the gully and the longitudinal edges of the collecting vessels, an advantageous development of the invention may consist in that the upper longitudinal gully edge, which is under the separator elements and parallel to which the collecting vessel(s) are slidable, is bent over, in particular has a U-shaped or V-shaped bend directed towards ~u the centre of the gully. In the position of use, the upper limb of the bend covers and protects the upper longitudinal edge of the collecting vessel(s) and, in relation to a horizontal plane, slopes downwards from the outside to the inside of the gully. This has the significant advantage that 2~ any condensate dropping off a separator element in this area, e.g. from its underside, cannot enter between collecting vessel and gully, but is conducted by the upper limb of the bend into the interior of the collecting vessel.
~0 Measures are taken in order that structural elements situated above the collecting vessels, for instance the upper limb of a gully bend, do not hinder the collecting vessels from being slid and removed. ~hese measures are that the upper edge of the end walls can be arranged lower than the embraced and J:~ protected longitudinal edge of the collecting vessel, or that between end wall and gully wall a slot may be provided which accommodates ~he upper limb of the U-shaped or V-shaped bend and receives the same in the region of the end walls. This slotting can be avoided if the gully has a raised longitudinal edge running slantwise upwards and outwards with the respective bend and thus there is sufficient inside volume in the collecting vessels, even though the end walls do not extend up as far as the area of the bends.
O A significant development of the invention forces the user to also remove and clean the separator elements or panels furnished with coulisses when he removes the collecting vessels. Due to the dimensions of such separator elements cleaning can be easily done in dishwashers. This development consists in that in the position of use the separator element~s) stop the collecting vessel(s) from sliding out of the gully and are detachably held. ~herefore the separator elements can be removed, releasing the collecting vessels for their movement. The user hence removes the separator elements ~u in order to be able to slide the collecting vessels out of the gully, empty and clean then. He can then likewise place the removed separator elements in a dishwasher.
It is advantageous if at least one separator element itself, or by means of a pro~ection arranged on it, engages with a collecting vessel from above, particularly with the rearmost collecting vessel during withdrawal from the gully, to a depth so as to overlap at least one end wall counter to the direction of slide necessary for removal. Often particularly ~u those separator elements ending directly in the gully or in the collecting vessels require cleaning. If the user first has to remove the separator elements to release the collecting vessels, he has then already done the main work for also cleaning these separator elements, for instance for 'J'~ p~a~ing the removed separator elements in a dishwasher.
Since the separator elements can also be fastened together and interlocked, the "unlocking" of the collecting vessel suitably necessitates the release of all the separator elements leading to the collecting vessels.
The gully and collecting vessels~s) in it slidable for emptying may have a mirror symmetrical profile with respect to a vertical, longitudinal median plane. This is an arrangement particularly well suited for underceilings, where separator elements with their coulisses or the like extend from either side and end in the gully and collecting vessels.
However it is also possible, particularly for hoods, to provide a gully-half with a correspondingly shaped collecting vessel. The gully wall overlapped by the separator is arranged slantwise in cross section and the cross section of the other gully wall, par~icularly one connected to a holder or the like, is arranged vertically or almost vertically. In this case separator elements extend only from one side and ~0 end in the collecting vessel~s). As for the rest, a hood can be provided having a substantially vertical end wall with the above-described gully and collecting vessels arranged at its lower edge.
2~ It is suitable if the stationary gully has a bar, lock or blocking device at the end at which the collecting vessels are removed as they are slid out. Unauthorized removal, signifying that the actual user of the kitchen or the like fails to notice or ls unaware that the collecting vessels 3~ are not in place, can thereby be prevented. In addition, by this means it can be ensured that the collecting vessels are fully inserted in the gully, because otherwise they cannot be barred, locked or blocked.
Mention was already made that the couplings protect and cover the gap between directly adjacent collecting vessels, in order that no condensate can enter there. A further development of the invention may consist in that the side J walls projecting beyond the end walls of directly adjacent collecting vessels overlap in the coupling area, so that there as well no gap, however narrow, remains outside the area of the end walls.
It is advantageous if the collecting vessel - having a substantially U-shaped bend of its end wall protectively lapping over the adjacent end wall of the next collecting vessel - has a side wall internally lapping over the side wall of this adjacent collecting vessel. This produces a tile-like arrangement in this overlapping area, preventing condensa~e from getting between the collecting vessels above the couplings at the side walls. The overlap is so large as to correspond to that in the area of the end walls.
~G In order that this overlapping of the side walls does not necessitate or produce any jamming of the collecting vessels, making it more difficult to release one collecting vessel from the next, it is suitable if the overlapped side wall of the one collecting vessel has an impression approximately of 2~ the thickness of the side wall overlapping it of the adjacent collecting vessel. Overlapping is hence facilitated by the impression mentioned, i.e. the side wall is shaped slightly outwardly in order that the internal overlap can be effected without jamming and deformation.
The overlapped wall area can be formed by a projection of the side wall, extending from the upper, free longitudinal edge to about the end wall or beneath the end wall and projecting relative to the end wall in the sliding direction by about ~û
the amount to which the V-shaped or U-shaped bend of the coupling pro~ects relative to the end wall.
The outward impression of the side wall can be arranged at the opposite end of the collecting vessel and be of a greater width in the longitudinal direction than the overlapping area, in order that the end pro~ection is sure to fit in the impressed area of the side wall of the adJacent collecting vessel.

A device for separating or removing condensate from the atmosphere of rooms, which is significantly simpler to clean because its gully cannot become foul, ensues particularly from combining the above-described features and measures ~5 singly or severally. The user therefore only has to remove, empty and clean the ~ollecting vessels lining and prote~ting the gully. At the same time assurance can be provided that the separator e~ements leading to these vessels also have to be cleaned, because they initially stop removal of the cu collecting vessels. The separator elements have to be detached from their holders in order to release the collecting vessels and likewise can then be simply placed in a dishwasher or similar cleaning device. Cleaning an underceiling at great height or the hard to reach interior of 2J an hood, along with the attendant inconveniences for the user and cleaner, are hence avoided.
An exemplary embodiment of the invention will be described in further detail below with reference to the drawings in which, ~0 partly in schematized form, Fig. 1 is a diagrammatic, partly broken away representation of a canteen with separators embodying the invention and taking the form of an underceiling and hoods, ~, Fig. 2 is a portion of a device em~odying the invention on an enlarged scale, including a gully and separator elements in slanting relationship thereto, the gully having collecting vessels arranged in it to keep it clean and these vessels being withdrawable in the longitudinal direction of the gully for emptying and cleaning, Fig. 3 is a plan view of the device illustrated in Fig. 2, the separators in the form of panels being depicted only in their region directly adjacent to the gully and otherwise being broken away, Fig. 4 is a front view of the device in Fig. 2, including a gully containing collecting vessels and the panels slanting from either side and ending in the gully to form a hood or as part of an underceiling for instance, 2u Fig. 5 is an enlarged, cross-sectional view of the gully and a collecting vessel arranged in it, the separator elements extending from either side and lapping over an end wall of ~he collecting vessel so as to stop it from being drawn out of the gully, ~5 Fig. 6 depicts two collecting vessels detachably coupled together in the direction of push and pull in a side view interrupted in the longitudinal direction, without the gully receiving them, including an end ~G handle on the foremost collecting vessel as considered in the direction of pull, Figs.6a to 6d are the details marked in Fig. 6, on an enlarged ~'J scale, Fig. 7 is a plan view of a collecting vessel, depicted in interrupted form, having at the one face two impressions and at the opposite face two corresponding, projecting extensions of its side walls, these extensions engaging with and overlapping the impressions of an ad~oining collecting vessel, and o Fig. ~3 is a section of part of the collecting vessel in Fig.

A device, generally designated i, evident particularly in i~ Figs. 2, 4 and 5, serves for separating or removing fatty or oily conden~ate from rooms 2 - cf. Fig. 1 - having an oily, fatty andJor s~eamy atmosphere, as exists in large-scale catering establishments, for instance.
~u Fig. 1 shows that the device 1 may be an underceiling, which is rendered operative particularly over the area of the range by appropriate inclination of the separator elements 3 yet to be described. These elements arranged above the area of the range may also take the form of hoods.
~ :~
According to Figs. 2 and 4, the separator elements 3 mentioned are held in a detachable condition by means of a supporting structure 4 and have channel-shaped, parallel coulisses 5 open on one side. The coulisses 5 have their open ~0 sides in partly overlapping relationship and have a passage for air between their edges. These coulisses 5 are combined to form panels as separator elements 3 which, according to Fig. 1, can be singly removed from their holders for cleaning in a dishwasher, for instance. The inclined coulisses 5 lead to oil, fat and moisture being condensed out of the air -conducted therethrough. Their inclination, which may also be at a smaller pitch than illustrated ln Fig. 4, means that this condensate is conducted to a gully 6 where these coulisses 5 end in accordance with Figures 4 and 5.
It is shown in Figures 2 to 5 and especially clearly in Fig.
5 that arranged in the gully 6 there is a collecting vessel 7 slidable in the direction of arrow Pf~ to depart so far from the gully 6 as to be removable. This collecting vessel 7 protects the gully 6 from the condensate delivered by the separator elements 3 and coulisses 5. Therefore this condensate does not wet and foul the gully 6 and thus this permanently installed gully 6 does not have to be cleaned.
Rathermore, cleaning can be effected simply and conveniently by from time to time withdrawing the collecting vessel 7 in the direction of arrow Pfl, emptying and cleaning it and sliding it back again. Since this collecting vessel 7 is situated in the gully 6, the separator elements 3 and their coulisses 5 end in this collecting vessel 7. According to ~ig. 3, the collecting vessel 7 covers and protects the entire gully length and thus the part of the gully 6 where the separator elements 3 or coulisses 5 end.
Fig. 5 shows that the upper, free longitudinal edge 8 of the 2~ collecting vessel 7 extends approximately level with the upper longitudinal ~dge of the gully 6, providing optimal utilization of space and a maximum capacity for the collecting vessel 7. One sees that the longitudinal edge 9 of the gully 6 runs slightly dbove the longitudinal edges 8 of 3~ the collecting vessel 7. This is so, because the upper longitudinal edge 9 of the gully 6, which is under the separators 3 and parallel to which the collecting vessel 7 is slidable, has a substantially U-shaped or V-shaped bend 10 directed towards the centre of the gully. In the position of ~se, the upper limb 11 of the bend 10 covers and protects the upper longitudinal edge 8 of the collecting vessel 7 and, in relation to a horizontal plane, slopes downwards from the outside to the inside of the gully 6 and thus to the inside of the collecting vessel 7. Should condensate deposit on and drain off the underside of the inclined separator element 3, dropping off it before reaching the collecting vessel 7, such condensate cannot get into the gap between collecting vessel 7 and gully 6, but is conducted by limb 11 into the collecting vessel 7.

While in the foregoing mention has been made of 'la"
collecting vessel 7, it is to be seen in the exemplary embodiment that a plurality of collecting vessels 7 are provided over the collecting area of the gully 6, hence in the exemplary embodiment throughout the length of the gully 6. These collecting vessels 7 are in mutual extension of, and in alignment with, one another and are closed by walls at either end, hereinafter referred to as end walls 12. In the position of use - as illustrated in Figs. 2, 3 and 6 - these cO vessels 12 abut without any appreciable gap. These collecting vessels 7 are coupled in the direction of push and pull and are detachably interconnected, as illustrated in greater detail in Figs. 6 and 6d. Therefore they are slidable together relative to, and withdrawable from, the gully 6, and ~'J can be slid back into the gully 6 after having been emptied and cleaned. These coupled together, individual collecting vessels 7 can hence be taken as or designated as a multipart collecting vessel 7. In the following they will be referred to as collecting vessel 7. That is to say, in the description 3~ below it is understood that a plurality of collecting vessels 7 coupled in the above-described manner is provided in the gully 6. This has the considerable advantage that given a gully 6 of relatively great length, it is readily possible for the collecting vessels 7 to be removed even in somewhat 3~ confined space conditions. A collecting vessel 7 corresponding in length to the overall length of the gully 6 would require a sufficiently large free space for ~ts withdrawal.
According to Fig. 5, the collecting vessels 7 have a cross-sectional profile corresponding approximately to the cross section of the internal contour of the gully 6. Therefore they can protect the gully 6 well and nevertheless hold as much condensate as the gully 6 could in their absence.
Fig. 6 illustrates that the end walls 12 of the collecting vessels 7 have a mutual stop as a pressure coupling when they are jointly moved for insertion. Further, the one end wall 12 is engaged by a pulling element - according to Fig. 6d a hook-shaped folded edge 13 - co-operating with the neighbouring vessel as a coupling in the direction of pull.
As already mentioned, a collecting vessel 7 has at the upper edge of one end wall 12 a hook-shaped, folded edge 13 which points away from that end wall 12 and engages over and behind ~O the directly adjoining, plain end wall 12 of the neighbouring collecting vessel a~cording to Fig. 6d. According to Fig. 6d, the upper edge of this plain end wall 12 may also be beadlike so as to compose an improved coupling and particularly to faciliate re-coupling.
2~
Once a first collecting vessel 7 has been drawn out of the gully 6 so far that its end wall 12 provided with the folded edge 13 is outside, the collecting vessel 7 can be raised slightly and thus its folded edge 13 can be released from the ~O adjacent end wall 12. Through the withdrawal of the first collecting vessel 7, the latter end wall 12 has now reached the end of the gully 6 and can therefore be grasped by an attendant for withdrawal of this second collecting vessel 7 which, in turn, draws along an adjacent collecting vessel 7 ~J with a corresponding coupling. This procedure is repeated ~, until the entire chain of collecting vessels 7 has been drawn out of the gully 6. The collecting vessels 7 are then emptied, cleaned and then slid back in the reverse order, whereby the folded edge 13 can be attached to the plain or 5 beaded end wall 12 shortly before the latter is fully inserted.
The hook-shaped folded edge 13 or the like extends without a gap throughout the end wall ~2 of the collecting vessel 7, at 0 least in the area which receives condensate for separation.
This folded edge 13 or the like reaches with its free edge 13a over the end wall 12 and its bead 12a of the adjacent collecting vessel 7. According to Fig. 6d, this free edge 13a is lower than the upper edge or bead 12a of the overlapped 1~ end wall 12. Therefore this hook-shaped folded edge 13 or the like not only forms a coupling in the direction of pull, but also bridges and covers the gap 14 between the two confronting end walls 12 of the two collecting vessels 7 directly adjacent to each other. That is to say, this folded edge 13 or the like has a double function by acting as a detachable coupling effective in the direction of pull, but also by preventing condensate from entering between the end walls 12.
In order that the protection of the gap 14 between the longitudinal edges 8 and 9 with the aid of the limb 14 does not hinder the collecting vessels 7 from sliding, the upper edge of the end walls 12 is in each case arranged lower than the embraced and protected longitudinal edge 8 of the collecting vessel 7. Were the upper edges of the end walls 12 to be in-plane with the longitudinal edges 8, a slot accommodating the upper limb 11 of the U-shaped or V-shaped bend 10 would have to be provided in the end walls 12 themselves or between them and the side wall 17 of the gully.
Such a slot is avoided by the selected difference in height of the respective edges.
Since condensate deposits, requiring cleaning, also collect on the separator elements 3 in the course of time, it is advantageous if the user is "forced" also to remove the separator elements 3 from their detachable holder for cleaning, when he empties the collecting vessels 7. In the exemplary embodiment it is therefore proposed that in the position of use the separator elements 3 stop the collecting vessel(s) from sliding out of the gully 6. In the present instance this is accomplished in that according to Fig. 5 at least one separator element 3 itself or a projection 16 arranged on it or belonging to its end wall engages with a collecting vessel 7 from above, e.g. with the rearmost collecting vessel 7 during withdrawal from the gully 6, to a depth so as to overlap at least one end wall 12 counter to the direction of slide necessary for removal. It is evident in Figure 5 that the end wall 12 situated there behind the ~0 pro~ections 16 of ~he separator elements 3 prevents its collecting vessel 7 from being withdrawn towards the viewer, perpendicular to the plane of the drawing.
It becomes clear particularly from Fig. 5, but also from the ~5 other Figures, that the gully 6 and the collecting vessels 7 in it slidable from the gully 6 for emptying and cleaning are mirror symmetrical or have a mirror symmetrical profile with respect to a vertical, longitudinal median plane L. This also applies if and when the device 1 is a hood acted upon from 3~ two sides.
If, however, a hood accessible only at one side is necessary, in comparison with Fig. 5 a gully "half" 6 with correspondingly shaped collecting vessels 7 may be provided.
~5 The g~lly side wall 17 overlapped by the separator 3 and l&
accordingly the side wall 15 of the collecting vessel 7 are arranged slantwise in cross section and the cross section of the other gully wall, particularly one connected to a holder or the like - approximately in plane L -, is arranged vertically or almost vertically. Therefore the representation of Fig. 5 can also be interpreted as one of a device 1 in the form of a hood, if plane L is formed as a vertical end wall and on one side only of it are a separator element 3, gully half 6 with vessel halves 7.
1 &
The stationary gully 6 may have a bar, lock or blocking device (not shown) at the end at which the collecting vessels 7 are removed as they are slid out in the direction of arrow Pfl. By this means, not only can unauthorized removal be prevented, but correct insertion of all the collecting vessels 7 is ensured if this bar or lock can be put into its closing position. If the collecting vessels 7 have not been duly inserted to a sufficient depth, or a coupling between two collecting vessels 7 has not been established during ~C insertion, i.e. the hook-shaped folded edge 13 fails to engage over the end wall 12 of the adjacent collecting vessel 7 but butts against it, the chain of collecting vessels 7 has a greater overall length. As a result, the last collecting vessel 7 cannot be fully inserted and hence prevents locking.
2~ Therefore not only is indication given as to whether the collecting vessels 7 are correctly positioned and there are no gaps remaining between individual collecting vessels 7, as would be provided merely by a projecting length of the last collecting vessel 7. Rathermore, the stop or similar lock to ~C be fitted forces the user to correct an error which has occured during insertion.
Mention was already made that the longitudinal edges 8 of the collecting vessels 7 are arranged higher than the edges of 7 'J
the end walls 12. This difference in height becomes apparent particularly in the longitudinal section of Fig. 6.
In order that condensate cannot enter between the side walls 15 in that area of the joint between two adjacent collecting vessels 7 which is no longer protected by the hook-shaped folded edges 13 or the like, those areas of the side walls 15 which project beyond the end walls 12 of the directly adjacent collecting vessels 7 overlap in their coupling lo area, as is illustrated particularly by Figs. 6 to 8.
Accordingly, it is proposed that the collecting vessel 7 -having a substantially U-shaped bend or folded edge 13 of its end wall 12 protectively lapping over the end wall 12 adjacent thereto and over the bead 12a provided there of the next collecting vessel 7 - has a side wall 15 internally lapping over the side wall 15 of this adjacent collecting vessel 7, resulting in a tile-like cover. According to Figs.
6 and 6d, the side wall 15 of the one collecting vessel 7 ~0 laps over that of the other vessel by about the extent to which the U-shaped or V-shaped folded edge 13 laps over the end wall 12. Therefore, all ln all, an overlap and protection of the same width is provided throughout the area of the gap 14 between two collecting vessels 7. Particularly Fig. 6d 2~ shows that the lower edge 13a of the hook-shaped folded edge 13 is arranged in-plane with the outermost edge 18 of an overlapping wall area 19 of the side wall 15.
Figures 7 and 8 as well as Figs. 6 and 6d illustrate that the overlapped side wall 15 of the one collecting vessel 7, hence that of the collecting vessel 7 situated on the right in Fig.
6, has an impression 20. This impression 20 is approximately of the thickness of the side wall 15 overlapping it of the adjacent collecting vessel 7 on the left in Fig. 6. This thickness or depth t of the impression 20 is shown in Fig. 8 ~U
and is the amount by which tha impression 20 is shaped outwardly to depart from the plane of the rest of the side wall 15 and from the interior of the collecting vessel 7.
According to Figs. 7, 6 and 6d, the overlapping wall area 19 is formed by a projection of the side wall 15 in the direction in which the gully 6 extends and in the direction in which the collecting vessel 7 is slid. This pro~ection extends from the upper, free longitudinal edge 8 to about the ,o end wall 12 or somewhat beneath the end wall 12. This pro~ection forming the overlapping wall area 19 projects relative to the end wall 12 by about the amount to which the V-shaped or U-shaped folded edge 13 of the coupling projects relative to the end wall 12, producing the already mentioned ,5 arrangement of edges 13a and 18 in a vertical plane.
The outward impression 20 af the side wall 15 is arranged at the opposite end of the collecting vessel 7, i.e. exactly at the end opposite to the overlapping wall area 19, and is of a ~0 greater width in the longitudinal direction than the overlapping wall area 19. In the position of use, wall area 19 is therefore sure to be within the impressed area of the impression 20, preventing jamming and an unintended frictional engagement in the overlapping area.

Altogether, a device 1 for separating condensate from oily, fatty and/or steamy atmospheres in large-scale catering establishments, for ex~mple, is provided wherein, in a seemingly contradictory ~anner, a gully 6 collects but is not fouled by condensate and hence does not have to be cleaned.
This is advantageous because this gully 6 can then be mounted permanently and thus correspondingly stably in order to capable of exercising a dual function by also acting as a carrier in the area of an underceiling or hood or a 3~ combïnation of both. A gully 6 detachable from a carrier does not have to be provided. This is accomplished in a simple way by providing the gully 6 with one or more collecting vessels 7 lining and protecting the inside of the gully. A plu~ality of collecting vessels 7 arranged in the direction in which the gully 6 extends has the advantage that they are removable one by one as they are drawn out of the gully 6. Therefore the space available in the withdrawal direction does not have to correspond to the length of the gully 6. Even when a plurality of collecting vessels 7 is used, each of a length 1G permitting easy extraction and removal and adapted to the spatial conditions, dirt is pre~ented from accumulating in the gully proper. This is so because the selected coupling between the individual collecting vessels 7 also covers the ~oints there and protects them against condensate entering 1~ the gap 14 between the collecting vessels 7.
The collecting vessel 7 arranged furthest to ~he left in Fig.
6 has a handle 21 for grasping the collecting vessel 7 when it is drawn out. In addition a locking device (not shown) might be applied and assume the use position when all the collecting vessels 7 have been duly inserted.
The device 1 for separating fatty, moisture-laden or oily condensate from rooms 2, for instance canteens, may be an underceiling, a hood or a combination of both. The device has known separator elements 3 which are held in a detachable condition by a supporting structure 4 in order that they can be cleaned in di~hwashers, for instance. These separator elements 3 have collecting elements or coulisses 5 for Lhe ~& condensate, inclined so as to conduct the condensate to a gully 6. At least one collecting vessel 7 or a chain of collecting vessels 7 is slidably and/or removably located in this gully 6, so that the condensate supplied by ~he separator element 3 or its coulisses 5 reaches this 3~ ~ollecting vessel 7. The permanently installed gully 6 is therefore protected from ~his condensate by the collec-~ing vessel~s) 7. For emptying and cleaning the collecting vessel~
7 they can be sli~ out of the gully 6.

It is advantageous if the collecting vessel(s) have a cross-sectional profile corresponding approximately to the cross section of the internal contour of the gully, automatically resulting in good guidance of the collecting vessel in the JU gully, without any risk of tilting and the like. Even if slightly deformed, the collecting vessel - as considered over the entire length - can lie relatively loosely in the gully and be slid with corresponding ease.
:
Claims 6 to 8 recite developments of the invention, particularly of the collecting vessels and the way in which they are detachably coupled together. The features and measures recited in these claims provide structurally simple possibilities for a plurality of collecting vessels, aligned in the gully and substantially contiguous in the position of use, to be connected in the direction of push and pull. At the same time assurance is provided that the ~oint between two such ad~acent collecting vessels is covered, preventing ,u any condensate there from getting in between the collecting vessels and entering the underlying gully.
In connection with the arrangement of the longitudinal edges of the gully and the longitudinal edges of the collecting vessels, an advantageous development of the invention may consist in that the upper longitudinal gully edge, which is under the separator elements and parallel to which the collecting vessel(s) are slidable, is bent over, in particular has a U-shaped or V-shaped bend directed towards ~u the centre of the gully. In the position of use, the upper limb of the bend covers and protects the upper longitudinal edge of the collecting vessel(s) and, in relation to a horizontal plane, slopes downwards from the outside to the inside of the gully. This has the significant advantage that 2~ any condensate dropping off a separator element in this area, e.g. from its underside, cannot enter between collecting vessel and gully, but is conducted by the upper limb of the bend into the interior of the collecting vessel.
~0 Measures are taken in order that structural elements situated above the collecting vessels, for instance the upper limb of a gully bend, do not hinder the collecting vessels from being slid and removed. ~hese measures are that the upper edge of the end walls can be arranged lower than the embraced and J:~ protected longitudinal edge of the collecting vessel, or that between end wall and gully wall a slot may be provided which accommodates ~he upper limb of the U-shaped or V-shaped bend and receives the same in the region of the end walls. This slotting can be avoided if the gully has a raised longitudinal edge running slantwise upwards and outwards with the respective bend and thus there is sufficient inside volume in the collecting vessels, even though the end walls do not extend up as far as the area of the bends.
O A significant development of the invention forces the user to also remove and clean the separator elements or panels furnished with coulisses when he removes the collecting vessels. Due to the dimensions of such separator elements cleaning can be easily done in dishwashers. This development consists in that in the position of use the separator element~s) stop the collecting vessel(s) from sliding out of the gully and are detachably held. ~herefore the separator elements can be removed, releasing the collecting vessels for their movement. The user hence removes the separator elements ~u in order to be able to slide the collecting vessels out of the gully, empty and clean then. He can then likewise place the removed separator elements in a dishwasher.
It is advantageous if at least one separator element itself, or by means of a pro~ection arranged on it, engages with a collecting vessel from above, particularly with the rearmost collecting vessel during withdrawal from the gully, to a depth so as to overlap at least one end wall counter to the direction of slide necessary for removal. Often particularly ~u those separator elements ending directly in the gully or in the collecting vessels require cleaning. If the user first has to remove the separator elements to release the collecting vessels, he has then already done the main work for also cleaning these separator elements, for instance for 'J'~ p~a~ing the removed separator elements in a dishwasher.
Since the separator elements can also be fastened together and interlocked, the "unlocking" of the collecting vessel suitably necessitates the release of all the separator elements leading to the collecting vessels.
The gully and collecting vessels~s) in it slidable for emptying may have a mirror symmetrical profile with respect to a vertical, longitudinal median plane. This is an arrangement particularly well suited for underceilings, where separator elements with their coulisses or the like extend from either side and end in the gully and collecting vessels.
However it is also possible, particularly for hoods, to provide a gully-half with a correspondingly shaped collecting vessel. The gully wall overlapped by the separator is arranged slantwise in cross section and the cross section of the other gully wall, par~icularly one connected to a holder or the like, is arranged vertically or almost vertically. In this case separator elements extend only from one side and ~0 end in the collecting vessel~s). As for the rest, a hood can be provided having a substantially vertical end wall with the above-described gully and collecting vessels arranged at its lower edge.
2~ It is suitable if the stationary gully has a bar, lock or blocking device at the end at which the collecting vessels are removed as they are slid out. Unauthorized removal, signifying that the actual user of the kitchen or the like fails to notice or ls unaware that the collecting vessels 3~ are not in place, can thereby be prevented. In addition, by this means it can be ensured that the collecting vessels are fully inserted in the gully, because otherwise they cannot be barred, locked or blocked.
Mention was already made that the couplings protect and cover the gap between directly adjacent collecting vessels, in order that no condensate can enter there. A further development of the invention may consist in that the side J walls projecting beyond the end walls of directly adjacent collecting vessels overlap in the coupling area, so that there as well no gap, however narrow, remains outside the area of the end walls.
It is advantageous if the collecting vessel - having a substantially U-shaped bend of its end wall protectively lapping over the adjacent end wall of the next collecting vessel - has a side wall internally lapping over the side wall of this adjacent collecting vessel. This produces a tile-like arrangement in this overlapping area, preventing condensa~e from getting between the collecting vessels above the couplings at the side walls. The overlap is so large as to correspond to that in the area of the end walls.
~G In order that this overlapping of the side walls does not necessitate or produce any jamming of the collecting vessels, making it more difficult to release one collecting vessel from the next, it is suitable if the overlapped side wall of the one collecting vessel has an impression approximately of 2~ the thickness of the side wall overlapping it of the adjacent collecting vessel. Overlapping is hence facilitated by the impression mentioned, i.e. the side wall is shaped slightly outwardly in order that the internal overlap can be effected without jamming and deformation.
The overlapped wall area can be formed by a projection of the side wall, extending from the upper, free longitudinal edge to about the end wall or beneath the end wall and projecting relative to the end wall in the sliding direction by about ~û
the amount to which the V-shaped or U-shaped bend of the coupling pro~ects relative to the end wall.
The outward impression of the side wall can be arranged at the opposite end of the collecting vessel and be of a greater width in the longitudinal direction than the overlapping area, in order that the end pro~ection is sure to fit in the impressed area of the side wall of the adJacent collecting vessel.

A device for separating or removing condensate from the atmosphere of rooms, which is significantly simpler to clean because its gully cannot become foul, ensues particularly from combining the above-described features and measures ~5 singly or severally. The user therefore only has to remove, empty and clean the ~ollecting vessels lining and prote~ting the gully. At the same time assurance can be provided that the separator e~ements leading to these vessels also have to be cleaned, because they initially stop removal of the cu collecting vessels. The separator elements have to be detached from their holders in order to release the collecting vessels and likewise can then be simply placed in a dishwasher or similar cleaning device. Cleaning an underceiling at great height or the hard to reach interior of 2J an hood, along with the attendant inconveniences for the user and cleaner, are hence avoided.
An exemplary embodiment of the invention will be described in further detail below with reference to the drawings in which, ~0 partly in schematized form, Fig. 1 is a diagrammatic, partly broken away representation of a canteen with separators embodying the invention and taking the form of an underceiling and hoods, ~, Fig. 2 is a portion of a device em~odying the invention on an enlarged scale, including a gully and separator elements in slanting relationship thereto, the gully having collecting vessels arranged in it to keep it clean and these vessels being withdrawable in the longitudinal direction of the gully for emptying and cleaning, Fig. 3 is a plan view of the device illustrated in Fig. 2, the separators in the form of panels being depicted only in their region directly adjacent to the gully and otherwise being broken away, Fig. 4 is a front view of the device in Fig. 2, including a gully containing collecting vessels and the panels slanting from either side and ending in the gully to form a hood or as part of an underceiling for instance, 2u Fig. 5 is an enlarged, cross-sectional view of the gully and a collecting vessel arranged in it, the separator elements extending from either side and lapping over an end wall of ~he collecting vessel so as to stop it from being drawn out of the gully, ~5 Fig. 6 depicts two collecting vessels detachably coupled together in the direction of push and pull in a side view interrupted in the longitudinal direction, without the gully receiving them, including an end ~G handle on the foremost collecting vessel as considered in the direction of pull, Figs.6a to 6d are the details marked in Fig. 6, on an enlarged ~'J scale, Fig. 7 is a plan view of a collecting vessel, depicted in interrupted form, having at the one face two impressions and at the opposite face two corresponding, projecting extensions of its side walls, these extensions engaging with and overlapping the impressions of an ad~oining collecting vessel, and o Fig. ~3 is a section of part of the collecting vessel in Fig.
7, taken through the area of the impression of its side wall.
A device, generally designated i, evident particularly in i~ Figs. 2, 4 and 5, serves for separating or removing fatty or oily conden~ate from rooms 2 - cf. Fig. 1 - having an oily, fatty andJor s~eamy atmosphere, as exists in large-scale catering establishments, for instance.
~u Fig. 1 shows that the device 1 may be an underceiling, which is rendered operative particularly over the area of the range by appropriate inclination of the separator elements 3 yet to be described. These elements arranged above the area of the range may also take the form of hoods.
~ :~
According to Figs. 2 and 4, the separator elements 3 mentioned are held in a detachable condition by means of a supporting structure 4 and have channel-shaped, parallel coulisses 5 open on one side. The coulisses 5 have their open ~0 sides in partly overlapping relationship and have a passage for air between their edges. These coulisses 5 are combined to form panels as separator elements 3 which, according to Fig. 1, can be singly removed from their holders for cleaning in a dishwasher, for instance. The inclined coulisses 5 lead to oil, fat and moisture being condensed out of the air -conducted therethrough. Their inclination, which may also be at a smaller pitch than illustrated ln Fig. 4, means that this condensate is conducted to a gully 6 where these coulisses 5 end in accordance with Figures 4 and 5.
It is shown in Figures 2 to 5 and especially clearly in Fig.
5 that arranged in the gully 6 there is a collecting vessel 7 slidable in the direction of arrow Pf~ to depart so far from the gully 6 as to be removable. This collecting vessel 7 protects the gully 6 from the condensate delivered by the separator elements 3 and coulisses 5. Therefore this condensate does not wet and foul the gully 6 and thus this permanently installed gully 6 does not have to be cleaned.
Rathermore, cleaning can be effected simply and conveniently by from time to time withdrawing the collecting vessel 7 in the direction of arrow Pfl, emptying and cleaning it and sliding it back again. Since this collecting vessel 7 is situated in the gully 6, the separator elements 3 and their coulisses 5 end in this collecting vessel 7. According to ~ig. 3, the collecting vessel 7 covers and protects the entire gully length and thus the part of the gully 6 where the separator elements 3 or coulisses 5 end.
Fig. 5 shows that the upper, free longitudinal edge 8 of the 2~ collecting vessel 7 extends approximately level with the upper longitudinal ~dge of the gully 6, providing optimal utilization of space and a maximum capacity for the collecting vessel 7. One sees that the longitudinal edge 9 of the gully 6 runs slightly dbove the longitudinal edges 8 of 3~ the collecting vessel 7. This is so, because the upper longitudinal edge 9 of the gully 6, which is under the separators 3 and parallel to which the collecting vessel 7 is slidable, has a substantially U-shaped or V-shaped bend 10 directed towards the centre of the gully. In the position of ~se, the upper limb 11 of the bend 10 covers and protects the upper longitudinal edge 8 of the collecting vessel 7 and, in relation to a horizontal plane, slopes downwards from the outside to the inside of the gully 6 and thus to the inside of the collecting vessel 7. Should condensate deposit on and drain off the underside of the inclined separator element 3, dropping off it before reaching the collecting vessel 7, such condensate cannot get into the gap between collecting vessel 7 and gully 6, but is conducted by limb 11 into the collecting vessel 7.

While in the foregoing mention has been made of 'la"
collecting vessel 7, it is to be seen in the exemplary embodiment that a plurality of collecting vessels 7 are provided over the collecting area of the gully 6, hence in the exemplary embodiment throughout the length of the gully 6. These collecting vessels 7 are in mutual extension of, and in alignment with, one another and are closed by walls at either end, hereinafter referred to as end walls 12. In the position of use - as illustrated in Figs. 2, 3 and 6 - these cO vessels 12 abut without any appreciable gap. These collecting vessels 7 are coupled in the direction of push and pull and are detachably interconnected, as illustrated in greater detail in Figs. 6 and 6d. Therefore they are slidable together relative to, and withdrawable from, the gully 6, and ~'J can be slid back into the gully 6 after having been emptied and cleaned. These coupled together, individual collecting vessels 7 can hence be taken as or designated as a multipart collecting vessel 7. In the following they will be referred to as collecting vessel 7. That is to say, in the description 3~ below it is understood that a plurality of collecting vessels 7 coupled in the above-described manner is provided in the gully 6. This has the considerable advantage that given a gully 6 of relatively great length, it is readily possible for the collecting vessels 7 to be removed even in somewhat 3~ confined space conditions. A collecting vessel 7 corresponding in length to the overall length of the gully 6 would require a sufficiently large free space for ~ts withdrawal.
According to Fig. 5, the collecting vessels 7 have a cross-sectional profile corresponding approximately to the cross section of the internal contour of the gully 6. Therefore they can protect the gully 6 well and nevertheless hold as much condensate as the gully 6 could in their absence.
Fig. 6 illustrates that the end walls 12 of the collecting vessels 7 have a mutual stop as a pressure coupling when they are jointly moved for insertion. Further, the one end wall 12 is engaged by a pulling element - according to Fig. 6d a hook-shaped folded edge 13 - co-operating with the neighbouring vessel as a coupling in the direction of pull.
As already mentioned, a collecting vessel 7 has at the upper edge of one end wall 12 a hook-shaped, folded edge 13 which points away from that end wall 12 and engages over and behind ~O the directly adjoining, plain end wall 12 of the neighbouring collecting vessel a~cording to Fig. 6d. According to Fig. 6d, the upper edge of this plain end wall 12 may also be beadlike so as to compose an improved coupling and particularly to faciliate re-coupling.
2~
Once a first collecting vessel 7 has been drawn out of the gully 6 so far that its end wall 12 provided with the folded edge 13 is outside, the collecting vessel 7 can be raised slightly and thus its folded edge 13 can be released from the ~O adjacent end wall 12. Through the withdrawal of the first collecting vessel 7, the latter end wall 12 has now reached the end of the gully 6 and can therefore be grasped by an attendant for withdrawal of this second collecting vessel 7 which, in turn, draws along an adjacent collecting vessel 7 ~J with a corresponding coupling. This procedure is repeated ~, until the entire chain of collecting vessels 7 has been drawn out of the gully 6. The collecting vessels 7 are then emptied, cleaned and then slid back in the reverse order, whereby the folded edge 13 can be attached to the plain or 5 beaded end wall 12 shortly before the latter is fully inserted.
The hook-shaped folded edge 13 or the like extends without a gap throughout the end wall ~2 of the collecting vessel 7, at 0 least in the area which receives condensate for separation.
This folded edge 13 or the like reaches with its free edge 13a over the end wall 12 and its bead 12a of the adjacent collecting vessel 7. According to Fig. 6d, this free edge 13a is lower than the upper edge or bead 12a of the overlapped 1~ end wall 12. Therefore this hook-shaped folded edge 13 or the like not only forms a coupling in the direction of pull, but also bridges and covers the gap 14 between the two confronting end walls 12 of the two collecting vessels 7 directly adjacent to each other. That is to say, this folded edge 13 or the like has a double function by acting as a detachable coupling effective in the direction of pull, but also by preventing condensate from entering between the end walls 12.
In order that the protection of the gap 14 between the longitudinal edges 8 and 9 with the aid of the limb 14 does not hinder the collecting vessels 7 from sliding, the upper edge of the end walls 12 is in each case arranged lower than the embraced and protected longitudinal edge 8 of the collecting vessel 7. Were the upper edges of the end walls 12 to be in-plane with the longitudinal edges 8, a slot accommodating the upper limb 11 of the U-shaped or V-shaped bend 10 would have to be provided in the end walls 12 themselves or between them and the side wall 17 of the gully.
Such a slot is avoided by the selected difference in height of the respective edges.
Since condensate deposits, requiring cleaning, also collect on the separator elements 3 in the course of time, it is advantageous if the user is "forced" also to remove the separator elements 3 from their detachable holder for cleaning, when he empties the collecting vessels 7. In the exemplary embodiment it is therefore proposed that in the position of use the separator elements 3 stop the collecting vessel(s) from sliding out of the gully 6. In the present instance this is accomplished in that according to Fig. 5 at least one separator element 3 itself or a projection 16 arranged on it or belonging to its end wall engages with a collecting vessel 7 from above, e.g. with the rearmost collecting vessel 7 during withdrawal from the gully 6, to a depth so as to overlap at least one end wall 12 counter to the direction of slide necessary for removal. It is evident in Figure 5 that the end wall 12 situated there behind the ~0 pro~ections 16 of ~he separator elements 3 prevents its collecting vessel 7 from being withdrawn towards the viewer, perpendicular to the plane of the drawing.
It becomes clear particularly from Fig. 5, but also from the ~5 other Figures, that the gully 6 and the collecting vessels 7 in it slidable from the gully 6 for emptying and cleaning are mirror symmetrical or have a mirror symmetrical profile with respect to a vertical, longitudinal median plane L. This also applies if and when the device 1 is a hood acted upon from 3~ two sides.
If, however, a hood accessible only at one side is necessary, in comparison with Fig. 5 a gully "half" 6 with correspondingly shaped collecting vessels 7 may be provided.
~5 The g~lly side wall 17 overlapped by the separator 3 and l&
accordingly the side wall 15 of the collecting vessel 7 are arranged slantwise in cross section and the cross section of the other gully wall, particularly one connected to a holder or the like - approximately in plane L -, is arranged vertically or almost vertically. Therefore the representation of Fig. 5 can also be interpreted as one of a device 1 in the form of a hood, if plane L is formed as a vertical end wall and on one side only of it are a separator element 3, gully half 6 with vessel halves 7.
1 &
The stationary gully 6 may have a bar, lock or blocking device (not shown) at the end at which the collecting vessels 7 are removed as they are slid out in the direction of arrow Pfl. By this means, not only can unauthorized removal be prevented, but correct insertion of all the collecting vessels 7 is ensured if this bar or lock can be put into its closing position. If the collecting vessels 7 have not been duly inserted to a sufficient depth, or a coupling between two collecting vessels 7 has not been established during ~C insertion, i.e. the hook-shaped folded edge 13 fails to engage over the end wall 12 of the adjacent collecting vessel 7 but butts against it, the chain of collecting vessels 7 has a greater overall length. As a result, the last collecting vessel 7 cannot be fully inserted and hence prevents locking.
2~ Therefore not only is indication given as to whether the collecting vessels 7 are correctly positioned and there are no gaps remaining between individual collecting vessels 7, as would be provided merely by a projecting length of the last collecting vessel 7. Rathermore, the stop or similar lock to ~C be fitted forces the user to correct an error which has occured during insertion.
Mention was already made that the longitudinal edges 8 of the collecting vessels 7 are arranged higher than the edges of 7 'J
the end walls 12. This difference in height becomes apparent particularly in the longitudinal section of Fig. 6.
In order that condensate cannot enter between the side walls 15 in that area of the joint between two adjacent collecting vessels 7 which is no longer protected by the hook-shaped folded edges 13 or the like, those areas of the side walls 15 which project beyond the end walls 12 of the directly adjacent collecting vessels 7 overlap in their coupling lo area, as is illustrated particularly by Figs. 6 to 8.
Accordingly, it is proposed that the collecting vessel 7 -having a substantially U-shaped bend or folded edge 13 of its end wall 12 protectively lapping over the end wall 12 adjacent thereto and over the bead 12a provided there of the next collecting vessel 7 - has a side wall 15 internally lapping over the side wall 15 of this adjacent collecting vessel 7, resulting in a tile-like cover. According to Figs.
6 and 6d, the side wall 15 of the one collecting vessel 7 ~0 laps over that of the other vessel by about the extent to which the U-shaped or V-shaped folded edge 13 laps over the end wall 12. Therefore, all ln all, an overlap and protection of the same width is provided throughout the area of the gap 14 between two collecting vessels 7. Particularly Fig. 6d 2~ shows that the lower edge 13a of the hook-shaped folded edge 13 is arranged in-plane with the outermost edge 18 of an overlapping wall area 19 of the side wall 15.
Figures 7 and 8 as well as Figs. 6 and 6d illustrate that the overlapped side wall 15 of the one collecting vessel 7, hence that of the collecting vessel 7 situated on the right in Fig.
6, has an impression 20. This impression 20 is approximately of the thickness of the side wall 15 overlapping it of the adjacent collecting vessel 7 on the left in Fig. 6. This thickness or depth t of the impression 20 is shown in Fig. 8 ~U
and is the amount by which tha impression 20 is shaped outwardly to depart from the plane of the rest of the side wall 15 and from the interior of the collecting vessel 7.
According to Figs. 7, 6 and 6d, the overlapping wall area 19 is formed by a projection of the side wall 15 in the direction in which the gully 6 extends and in the direction in which the collecting vessel 7 is slid. This pro~ection extends from the upper, free longitudinal edge 8 to about the ,o end wall 12 or somewhat beneath the end wall 12. This pro~ection forming the overlapping wall area 19 projects relative to the end wall 12 by about the amount to which the V-shaped or U-shaped folded edge 13 of the coupling projects relative to the end wall 12, producing the already mentioned ,5 arrangement of edges 13a and 18 in a vertical plane.
The outward impression 20 af the side wall 15 is arranged at the opposite end of the collecting vessel 7, i.e. exactly at the end opposite to the overlapping wall area 19, and is of a ~0 greater width in the longitudinal direction than the overlapping wall area 19. In the position of use, wall area 19 is therefore sure to be within the impressed area of the impression 20, preventing jamming and an unintended frictional engagement in the overlapping area.
2~
Altogether, a device 1 for separating condensate from oily, fatty and/or steamy atmospheres in large-scale catering establishments, for ex~mple, is provided wherein, in a seemingly contradictory ~anner, a gully 6 collects but is not fouled by condensate and hence does not have to be cleaned.
This is advantageous because this gully 6 can then be mounted permanently and thus correspondingly stably in order to capable of exercising a dual function by also acting as a carrier in the area of an underceiling or hood or a 3~ combïnation of both. A gully 6 detachable from a carrier does not have to be provided. This is accomplished in a simple way by providing the gully 6 with one or more collecting vessels 7 lining and protecting the inside of the gully. A plu~ality of collecting vessels 7 arranged in the direction in which the gully 6 extends has the advantage that they are removable one by one as they are drawn out of the gully 6. Therefore the space available in the withdrawal direction does not have to correspond to the length of the gully 6. Even when a plurality of collecting vessels 7 is used, each of a length 1G permitting easy extraction and removal and adapted to the spatial conditions, dirt is pre~ented from accumulating in the gully proper. This is so because the selected coupling between the individual collecting vessels 7 also covers the ~oints there and protects them against condensate entering 1~ the gap 14 between the collecting vessels 7.
The collecting vessel 7 arranged furthest to ~he left in Fig.
6 has a handle 21 for grasping the collecting vessel 7 when it is drawn out. In addition a locking device (not shown) might be applied and assume the use position when all the collecting vessels 7 have been duly inserted.
The device 1 for separating fatty, moisture-laden or oily condensate from rooms 2, for instance canteens, may be an underceiling, a hood or a combination of both. The device has known separator elements 3 which are held in a detachable condition by a supporting structure 4 in order that they can be cleaned in di~hwashers, for instance. These separator elements 3 have collecting elements or coulisses 5 for Lhe ~& condensate, inclined so as to conduct the condensate to a gully 6. At least one collecting vessel 7 or a chain of collecting vessels 7 is slidably and/or removably located in this gully 6, so that the condensate supplied by ~he separator element 3 or its coulisses 5 reaches this 3~ ~ollecting vessel 7. The permanently installed gully 6 is therefore protected from ~his condensate by the collec-~ing vessel~s) 7. For emptying and cleaning the collecting vessel~
7 they can be sli~ out of the gully 6.
