Description
- The present invention relates in general to a gutter-shaped siphon construction, suitable to be used in the floor of for instance a bathroom, a shower room, etc., for receiving and draining water. Such gutter-shaped siphon is known in practice. An example of a gutter-shaped siphon is disclosed in
WO-2007-004863 . - A gutter-shaped siphon generally has a design as schematically shown in
figures 1A and 1B. Figure 1A shows a schematic cross-section of a substantially U-shaped receivinggutter 10, with abottom 11,walls flanges walls flanges elongate entry opening 16. This gutter may for instance be bent as a whole from a plate, for instance a metal plate, but other embodiments are also possible. Theflanges bottom 11 may rest on a floor (not shown), for instance a concrete floor of a bathroom. The total height of thegutter 10 may for instance be about 5-6 cm. Thereceiving gutter 10 is connected to adrainpipe 20 directed substantially perpendicular to a side wall (the righthand side wall 12 in the figure), whichdrainpipe 20 may lie substantially horizontally on said floor and connect to drainpipes to a sewer or the like. At the location of thedrainpipe 20, thecorresponding side wall 12 is provided with apassage 17. - The function of the
receiving gutter 10 is receiving the water that ends up on the bottom of the shower cabin or shower tray during use. Then, the water flows from this bottom via the receiving gutter towards the drainpipe. If there would be no further provisions, thereceiving gutter 10 would empty when the supply of water stops, and there would be an open connection between the receiving gutter and the sewer, which will lead to stench annoyance in the bathroom concerned. In order to avoid this, thereceiving gutter 10 is provided with a stench valve or stench lock according to the well-known gooseneck principle, assuring that the airway from the sewer to the entry opening 16 of the gutter is always closed by an amount of water. To that end, acollection tray 40 is arranged in thereceiving gutter 10, having a closedbottom 41 and closedside walls collection tray 40 may be open at its upper side, as shown, and has an opening 47 in aside wall 42 communicating with thedrainpipe 20. In the example shown, thebottom 41 of the collectingtray 40 coincides with a part of thebottom 11 of thereceiving gutter 10 and saidside wall 42 of the collectingtray 40 coincides with a part of theside wall 12 of thereceiving gutter 10. Acap 60 is arranged over thecollecting tray 40, having a closedceiling 61 and closedside walls side walls cap 60, at least the highest point thereof, is at a lower level than the upper edge of theside walls tray 40, at least the lowest point thereof. - During use, water flows from the
receiving gutter 10 under thecap 60 into thecollecting tray 40, and from there towards thedrainpipe 20. When the water supply stops, a layer of water W remains standing in thereceiving gutter 10, of which, as shown in the figures, the height under normal circumstances is determined by the upper edge of theside walls tray 40, at least the lowest point thereof. Air from the sewer via thedrain pipe 20 can now not go beyond the space under thecap 60. In order to be able to escape from the receiving gutter, this air should have to pass under the lower edge of theside walls cap 60, at least the highest point thereof, but this course is blocked by the water W. - An important problem in the case of known gutter-shaped siphon designs is cleaning thereof. After some time, all kinds of pollutions collect in the receiving gutter, such as hairs and soap rests, which are difficult to flush away via the receiving
tray 40. It is true that it is possible to remove thecap 60, causing the gooseneck-shaped trajectory to be lifted, but still the upstanding side walls of the collectingtray 40 form a barrier. In the case of known gutter designs, it is further a disadvantage that parts are fixedly connected to thebottom 11 of thereceiving gutter 10. As a consequence, such gutters must be cleaned by hand. - An important aim of the present invention is to provide a gutter-shaped siphon design in which the said disadvantages are eliminated or at least reduced without reducing the functionality described.
- Another siphon system within a receiving drain, having the features of the preambles of claim 1 resp.
claim 12, is known fromEP1571269A . According to an important feature of the present invention, to this end a siphon system according to the present invention has the features of claim 1, and a drain system according to the present invention has the features ofclaim 12. - These and other aspects, features and advantages of the present invention will be further clarified by the following description with reference to the drawings, in which same reference numerals indicate same or similar parts, and in which:
-
figure 1A shows a schematic cross-section of a receiving gutter; -
figure 1B shows a schematic longitudinal section of a part of the receiving gutter offigure 1A ; -
figure 2A shows a horizontal cross-section of a part of a gutter-shaped siphon system according to the present invention; -
figure 2B on a larger scale shows a schematic cross-section of some parts of said siphon system; -
figure 2C shows a cross-section comparable tofigure 1A of a receiving gutter provided with a siphon system according to the present invention; -
figure 3 shows a schematic transparent perspective bottom view of a preferred embodiment of the siphon system according to the present invention; -
figure 4 shows a schematic perspective view of a cap in the siphon system according to the present invention. -
Figure 2A shows a horizontal cross-section of a part of a gutter-shaped siphon system 100 according to the present invention, andfigure 2B on a larger scale shows a schematic cross-section of some parts of thissiphon system 100, in dissembled condition. A disconnectable collecting tray is indicated byreference numeral 400. The disconnectable collectingtray 400 is connected to amounting flange 213 associated with the passage opening 17 of thegutter 10. Thismounting flange 213 may be fixedly connected to thewall 12 of thegutter 10, but preferably is a part of apipe coupling piece 200 disconnectably attached to thewall 12, which will be the first to be discussed hereunder. - The
pipe coupling piece 200 comprises atransfer tube segment 210 and acoupling sleeve 230. Thetransfer tube segment 210 comprises acylindrical tube part 211 having an outer surface that is provided with an outer threading over at least a part of its length, and is at anentrance end 212 provided with amounting flange 213 with radial dimensions larger than those of the said outer threading. On its side directed towards thepipe part 211, themounting flange 213 has apressing face 214 substantially perpendicular to the central axis of thepipe piece 211. Thecoupling sleeve 230 comprises a firstcylindrical pipe piece 231 and a secondcylindrical pipe piece 232, which are arranged aligned with each other and which can be made as a whole. The secondcylindrical pipe piece 232 is shown with smaller radial dimensions than the firstcylindrical pipe piece 231, the inner diameter of the secondcylindrical pipe piece 232 being equal to the inner diameter of thecylindrical pipe piece 211 of thetransfer pipe segment 210, which is preferred but not essential. The firstcylindrical pipe piece 231 has an inner surface that is provided with an inner threading over at least a part of its length, matching the outer threading of thetransfer pipe segment 210. On its end directed away from the secondcylindrical pipe piece 232, the firstcylindrical pipe piece 231 has anend face 234 substantially perpendicular to the central axis of thepipe piece 231. - Before use, a
receiving gutter 10 is provided with a circular passage opening 17 in a longitudinal wall 12 (seefigure 1A ), with a diameter slightly larger than the outer diameter of the outer threading of thetransfer pipe segment 210. Thistransfer pipe segment 210 is placed in thereceiving gutter 10, and itscylindrical pipe piece 211 is pushed through the passage opening 17 from the inside. Subsequently, at the outside of thereceiving gutter 10, the firstcylindrical pipe part 231 of thecoupling sleeve 230 is screwed onto thecylindrical pipe piece 211 of thetransfer pipe segment 210, wherein thewall 12 of the receiving gutter 10 (shown in dotted lines infigure 2 ) is clamped between on the one hand thepressing face 214 of themounting flange 213 of thetransfer pipe segment 210 and on the other hand theend face 234 of the firstcylindrical pipe part 231 of thecoupling sleeve 230. - In principle, a sufficient sealing will be achieved here with respect to the
wall 12 of the receivinggutter 10, it being noted that the water to be drained from a shower tray is not under a high pressure. Preferably however, and as shown, acircular groove 235 is arranged is the saidend face 234 for accommodating an O-ring (not shown for sake of simplicity). This O-ring assures an even better water-tight sealing with respect to the outer side of the receivinggutter wall 12. Alternatively, or additionally, such O-ring accommodating groove might also be arranged in the said pressingface 214 of thetransfer pipe segment 210. - Now, the receiving
gutter 10 with thepipe coupling piece 200 attached thereto can be mounted on its destined position, and a drain pipe can be connected to the secondcylindrical pipe part 232, for instance by gluing. After placing the receiving gutter and for instance a shower tray, or the application of a shower floor or the like, thecoupling sleeve 230 is no longer accessible from outside. - The design described is particularly useful for providing a gutter with a pipe coupling piece with which a drain pipe can be coupled to the gutter. However, there are also other ways to achieve this. For instance, a pipe coupling piece may be glued to the gutter. In the context of the present invention, it is important that a mounting
flange 213, extending around the drain opening of the gutter, is present at the inner side of the gutter. - According to a further aspect of the present invention, the mounting
flange 213 has, at its side directed away from thepipe part 211, acoupling face 215 substantially perpendicular to the central axis of thepipe part 211, as well as two substantially vertically directedguide members 216 with a substantially L-shaped cross-section at opposite sides of saidcoupling face 215. Eachguide member 216 has a body part 217 directed substantially perpendicular to thecoupling face 215 and, at the end thereof directed away from thecoupling face 215, a leg part 218 directed substantially parallel to thecoupling face 215, the leg parts 218 being directed towards each other. - A collecting
tray 400 implemented according to this aspect of the present invention preferably has a substantially elongate shape and has apassage opening 407 with aconnection flange 410 in one of itslongitudinal side walls 402. At its side directed away from thetray 400, theconnection flange 410 has acoupling face 415. - The collecting
tray 400 may have a horizontal bottom and vertical walls, butfigure 3 illustrates that thetray 400 preferably has a contour of half a circle. Theconnection flange 410 preferably has vertical side edges, and may as a whole have a square or rectangular contour. The dimensions of thisconnection flange 410 match those of the saidguide members 216. Thecollection tray 400 can be mounted by placing itsconnection flange 410 from the top into theguide members 216 and to move it downwards. A correct vertical position is achieved by a stop. This stop may for instance be formed at the lower end of theguide members 216; then, thecollection tray 400 achieves its correct vertical position when theconnection flange 410 abuts this stop. This stop may for instance also be formed at the upper end of theconnection flange 410, as illustrated by a dottedline 411; then, thecollection tray 400 achieves its correct vertical position when aguide member 216 abuts this stop. - In the correct vertical position (operational position) of the collecting
tray 400, itspassage opening 407 is aligned with thepipe part 211 of thepipe coupling piece 200, thecoupling face 415 of theconnection flange 410 of the collectingtray 400 lying flush against thecoupling face 215 of the mountingflange 213 of thepipe coupling piece 200. Water reaching the collectingtray 400 thus flows away via thetransfer pipe segment 210 and thecoupling sleeve 230 towards the sewer. In the case of a good dimensioning of theconnection flange 410 and theguide members 216, a sufficient sealing will be achieved in principle between the coupling faces 215 and 415 in this case, it being noted that the water to be drained in the collecting tray is not under a high pressure. Preferably however, and as shown, acircular groove 416 is arranged in thecoupling face 415 of theconnection flange 410 of the collectingtray 400, for accommodating an O-ring (not shown for sake of simplicity). This O-ring assures an even better water-tight sealing between the coupling faces 215 and 415. Alternatively, such O-ring accommodating groove might also be arranged in thecoupling face 215 of thetransfer pipe segment 210. -
Figure 4 shows a schematic perspective view of the preferred embodiment of thecap 600 according to the present invention illustrated infigure 3 , of which the function is comparable to thecap 60 discussed in the introduction. Thecap 600 has a substantially rectangular contour, with anupper wall 601, afront wall 602, arear wall 603 andside walls 604. Thecap 600 is open at its lower side. In itsfront wall 602, thecap 600 is provided with a substantially recess 610, connected to thelower edge 605 of thefront wall 602, and confined byvertical edges 612 and a horizontalupper edge 611. Also thecap 600 is carried by thepipe coupling piece 200. To this end, the mountingflange 213 of thepipe coupling piece 200 has a step-shapedrecess 260 adjacent thepressing face 214. This step-shapedrecess 260 comprises wall parts 261 directed substantially parallel to the central axis of thepipe coupling piece 200, connecting to thepressing face 214, and a wall 262 directed substantially perpendicular to the central axis of thepipe coupling piece 200, connecting to said wall part 261. The longitudinal dimensions of said wall parts 261 correspond to the thickness of thefront wall 602 of thecap 600, and the mutual distance between said wall parts 261 corresponds to the mutual distance between theedges 612 of thecap recess 610. Thecap 600 is placed over thetray 400 with a vertical movement directed downwards, wherein the pipe coupling piece extends through thecap recess 610, and wherein the capfront wall 602 fits closely around the step-shapedrecess 260 of the mountingflange 213 and is confined closely between thewall 12 of thegutter 10 and the wall 262 of the mountingflange 213. This fitting is sufficient seailing to counteract escaping air and to thus counteract stench annoyance. - Before normal use, an ornamental grille (not shown) may be arranged over the
gutter 10. - When it is desired to clean the receiving
gutter 10, the possible ornamental grille is removed, and then thecap 600 can be removed by a sliding movement directed upwards. After that, the collectingtray 400 can be removed, also by a sliding movement directed upwards, wherein the mountingflange 410 of the cap slides in thevertical guide members 216. Now, the entire receivinggutter 10 is free, and can easily be flushed clean, wherein dirt parts can flow away with the flushing water directly through thetransfer pipe segment 210. After that, the collectingtray 400 and thecap 600 can, after also being flushed clean if desired, be placed again by a sliding movement directed downwards, and after placing the possible ornamental grille the device is again ready for use. - Thus the present invention provides a gutter-shaped siphon design of which the interior components are completely dismountable in a particularly simple manner to be able to clean the gutter well.
- It is noted that the present invention is particularly applicable in the case of elongate gutter designs, wherein the elongate side walls of the gutter are planar, but, with some obvious modifications, the present invention can also be applied in embodiments where the outer wall of the receiving gutter (or receiving tray) is curved.
- It is further noted that the present invention is also embodied in a siphon system for a receiving gutter (or receiving tray), comprising the collecting
tray 400, thecap 600, and thepipe coupling piece 200, which siphon system is indicated by thereference numeral 100. A receiving gutter (or receiving tray) provided with such siphonsystem 100 is indicated asdrain system 700. - By way of example, it has been mentioned in the above that the receiving
gutter 10 may be made of for instance a metal plate. In such case, the wall thickness of thegutter 10 will be some millimetres only. However, it is also possible that the receiving gutter is made from a thicker material, for instance plastic or marble. The length of thecylindrical pipe part 211 provided with threading of thetransfer pipe segment 210 is large enough, typically some centimetres, to accommodate such differences in thickness. - It will be clear for a person skilled in the art that the invention is not limited to the exemplary embodiments discussed in the above, but that several variations and modifications are possible within the protective scope of the invention as defined in the attached claims. Features which are only described for a certain embodiment can also be applied in other embodiments described, as long as falling within the scope as defined by the claims. Features of different embodiments may be combined to achieve another embodiment, as long as falling within the scope as defined by the claims. Features which have not been explicitly described as being essential may also be omitted.
- It is for instance possible that the collecting
tray 400 is provided with vertically directed guide member with a substantially L-shaped cross-section, engaging around the mountingflange 213. - It is further possible that the
upper wall 601 of thecap 600 is provided with venting holes.
