Definitions

  • the invention relates to a sanitary facility comprising a urinal and a suction siphon to be connected or connected to the urinal, the urinal having a basin area and an adjoining channel-like outlet which has an upwardly extending leg and a side extending leg, the upwardly extending leg ends above the maximum water level of the suction siphon and wherein the suction siphon is to be or is connected to the leg extending to the side.
  • the upwardly extending leg is referred to as the "vertical leg” and the leg extending to the side as the "horizontal leg", since the legs in the assembly position to which the information relates are at least predominantly one Extend vertically in the other case and horizontally in the other case. This applies to all the embodiments and variants of the invention described below and to the description of the figures.
  • Such a sanitary facility comprising a suction siphon enables active flushing, that is to say drawing off the liquid to be removed by active suction. If the flushing is triggered, the flushing water flows into the basin area with relatively low pressure but high volume flow, with the flushing water either being supplied via a flushing rim that encompasses the top of the basin area in sections or a so-called “rimless” flushing, which does not have a closed flushing rim and is distributed over almost the entire pool area and flows to the outlet.
  • the siphon is completely filled with water up to its upper edge, and due to the height difference, the water flows out of the siphon with a high volume flow This leads to a negative pressure being created there, which causes the liquid to be drained from the urinal to be actively sucked out of the outlet or the basin area.
  • This vacuum controlled The suction process continues until the fluid channel consisting of the outlet and siphon is no longer closed by a water column, so that the suction siphon then draws air through the fluid channel which is then open and the negative pressure collapses. It is then necessary to refill the siphon at least partially with water in order to ensure an odor trap, that is to say to close this channel again locally.
  • the suction effect only begins when the water column in the basin or outlet or in the vertical outlet leg is sufficient. If the water column is not high enough, there is no negative pressure and the siphon works as a pure displacement siphon. In order to ensure this, the flushing water is supplied with a sufficiently high volume flow over the flushing rim in known sanitary facilities. The rinsing water, because it is supplied at a relatively low pressure, flows relatively slowly into the basin, so that the water column does not build up too quickly or a high volume flow is used to accelerate this. This relatively slow inflow also ensures that the siphon is refilled to form the odor trap after the flushing process has ended, i.e. when no more flushing water is supplied.
  • the invention is therefore based on the problem of specifying a sanitary facility which is improved in comparison.
  • a flushing nozzle is provided on the urinal, via which flushing water can be flushed into the basin area under pressure is, and that a device comprising a flushing water channel is provided for refilling the suction siphon with flushing water after completion of the suction process.
  • the sanitary facility according to the invention is characterized by a flushing nozzle provided on the urinal side, which is usually provided in the upper pelvic area on the wall-side, that is to say the rear pelvic wall.
  • the rinsing water is supplied via this rinsing nozzle at a higher pressure compared to rinsing via a rinsing rim, i.e. sprayed under pressure from the rinsing nozzle onto the basin wall, on which it is then distributed at high flow speed and flows very quickly to the outlet.
  • This rinsing enables very efficient cleaning and efficient rinsing of the liquid to be discharged, although significantly less rinsing water is required compared to the previously usual supply via the rinsing rim.
  • the invention advantageously provides a corresponding device with a flushing water channel via which, after the actual flushing water supply has ended, into the Basin area, a certain amount of rinsing water is led into the outlet, so that in the spiral siphon in the lower winding siphon area collects enough water and closes the siphon cross-section as an odor trap.
  • the invention therefore enables for the first time the combination of a urinal having a flushing nozzle with a suction siphon, since according to the invention the restoration of the odor trap is ensured with the arrangement of the separate refilling device with the flushing water channel running externally to the basin area.
  • the sanitary device according to the invention thus combines the high cleaning efficiency via the flushing nozzle, combined with very low flushing water consumption, while at the same time ensuring the formation of an odor trap.
  • the refilling device comprising the flushing water channel running separately from the basin area is the central means for ensuring the siphon refilling and thus the formation of the odor trap.
  • the flushing water channel can be integrated in the urinal.
  • the urinal itself is mostly made of ceramic and is a one-piece, fired component.
  • the flushing water channel is now directly integrated into this component.
  • this can be achieved in that the flushing channel is formed on the one-piece ceramic component itself, that is to say it is also formed during the casting of the body.
  • a corresponding ceramic component to the back of the urinal and to hinge it on, i.e. to bind it using a corresponding adhesive slurry that can be hardened in the later firing process and then to burn this shards equipped with the ceramic component so that the ceramic component of the flush water channel is integral with the actual urinal body is connected.
  • the flushing water channel is integrated into the urinal itself on the finished urinal; it runs virtually on the back of the urinal.
  • the flushing water channel expediently opens into the horizontal leg of the outlet, which is formed via a ceramic nozzle and to the the suction siphon connects. This means that the rinsing water used for the odor trap is supplied directly in front of the siphon and consequently also reaches the siphon directly, so that the odor trap is formed there as quickly as possible.
  • the flushing water channel is formed with a separate channel component attached to the urinal.
  • a corresponding channel component is attached to the back of the finished urinal, for example in the form of a line, a hose or a water tank or the like, which channel component is of course connected accordingly in order to direct the flushing water to the siphon.
  • This connection can be in the area of the horizontal leg of the outlet, which means that the channel component is arranged on the ceramic socket and the flushing water channel opens into the horizontal outlet leg.
  • the connection can also be on the siphon itself, which means that the flushing water channel opens directly into the siphon, and consequently the flushing water forming the odor trap is also fed directly into the siphon.
  • a bore or a connecting piece can be provided on the urinal or on the siphon, to which the channel component is to be connected or connected, that is, the flushing water channel opens at this bore or the connecting piece.
  • the flushing water channel is preferably supplied with flushing water via the same flushing water supply line via which the flushing water is fed to the flushing nozzle.
  • part of the supplied flushing water is consequently "branched off” and fed to the flushing water channel. Via this it is then led in a corresponding manner into the outlet or siphon, at the same time ensuring that a sufficient amount of flushing water continues to run even after the actual flushing water supply has ended.
  • flushing water channel is supplied separately with flushing water.
  • a switchable valve can be assigned to this flushing water channel, which can be controlled accordingly, so that flushing water is only fed into the flushing water channel when the suction siphon is to be refilled and no more flushing water flows through the flushing nozzle.
  • a particularly advantageous development of the invention provides that means for delaying the inflow of the flushing water into the suction siphon are provided in the flushing water channel, and / or that the flushing water channel has a length ensuring a delayed flushing water inflow.
  • the flushing water channel provides the possibility that, after the actual flushing water supply has ended, a sufficient amount of water to fill up the siphon to form an odor trap is added via the flushing nozzle. If the rinsing water supply into the rinsing water channel is coupled with the rinsing water supply to the rinsing nozzle, then when the rinsing water supply to the rinsing nozzle is ended, no more rinsing water is fed into the rinsing water channel.
  • the flushing water channel is designed in such a way that the flushing water present in it, which, because it is supplied at a correspondingly high pressure, accumulates in the flushing water channel during the supply period, flows only with a delay from the flushing water channel into the outlet / siphon, so that it flows through it for a certain time After the flushing water supply has ended, it is ensured that water continues to flow out of the flushing water channel.
  • Appropriate delay means are included in the Rinsing water channel provided, so quasi flow obstacles or the like, which prevent an unimpeded outflow or delay the outflow.
  • the flushing water channel can also have a sufficient length or be guided in a suitable manner, so that only a slowed out flow results.
  • a delayed flushing water flow is consequently achieved in a more or less constructive manner, which enables a delayed run-on solely via the flushing water channel, at a time when no more flushing water flows in via the basin.
  • One or more flow obstacles which the rinsing water must flow around, and which consequently lengthen the fluid path, can be provided, for example, in the rinsing water channel as the delay means.
  • the flow cross-section of the flow channel can also change over its length at one or more points, that is, it can become wider or narrower, which also has an influence on the flow velocity.
  • the flushing water channel can also branch into two or more channel sections which converge again to the mouth in the outlet or in the siphon.
  • the flushing water channel can also be wound one or more times between the flushing water inlet and the flushing water outlet, i.e. it can be guided in a quasi-serpentine or meandering manner, whereby, of course, sections with only a slight gradient can also be realized, which also reduces the flow rate.
  • the vertical leg of the outlet has a length of 5-12 cm, in particular 6-9 cm and a cross-sectional area of 8-14 cm 2 , in particular between 9-11 cm 2 .
  • the height of the vertical leg is measured from its lower transition into the horizontal leg to the upper leg edge, where the leg opens towards the pelvic area.
  • the cross-sectional area can be constant over the height, or widen slightly upwards, for example over an approximately conical cross-sectional shape.
  • the volume of the refill device i.e. ultimately the flushing water channel, should be between 50 - 200 ml, adapted to the siphon, whereby the refill device is not completely filled with water during the supply time, especially with a larger volume.
  • This size or amount of water is sufficient, since the suction siphon itself typically needs approx. 50 - 70 ml to form the odor trap. Since there is still a residual amount of flushing water in the siphon when the suction process collapses, the amount in the flushing channel is sufficient to fill the suction siphon sufficiently to form the odor trap.
  • the flushing nozzle has a water connection pipe on which a flushing water outlet that communicates with the flushing water channel is also provided.
  • the flushing nozzle is therefore designed as a piece of pipe that has a nozzle head at one end, which is arranged in the basin area, while the water connection pipe extends through the basin wall to the rear of the urinal, where, for example, a lock nut is screwed onto the threaded connector there in order to fix the flushing nozzle, and where the flushing water supply line is connected.
  • a corresponding flushing water outlet is provided on this water connection pipe which, when the flushing nozzle is installed, communicates with the flushing water channel, if this is integrated on the urinal side, if this is separate.
  • the flushing water outlet can be designed as a radial bore or as a radially protruding connection piece.
  • a bore is expediently provided when the flushing water channel is integrated on the urinal side.
  • a connection piece is provided, for example, when the flushing water channel is formed via a separate hose or a separate line.
  • the flushing nozzle itself expediently has two first outlet channels, which run on opposite sides of the flushing nozzle and at an angle to the horizontal, two second outlet channels, which run on both sides and at the same or a greater angle to the horizontal, like the two first outlet channels, as well a central outlet located between the two second outlets.
  • a total of five outlets are therefore provided, which show different outlet directions, so that it is ensured that the flushing water discharged via the flushing nozzle is fanned out relatively broadly and can consequently flow around the entire basin area.
  • the first two outlet channels ensure that the flushing water flows relatively far in the upper edge area of the basin from the rear wall to the front wall.
  • the two second outlet channels serve the central area, so to speak, while the third outlet, which is arranged in the middle, flushes the rear wall.
  • the first and second outlet channels can have a common inlet and can be separated by a partition. This enables a common water supply with a simple possibility of dividing it at the same time.
  • the angle of the first outlet channels to the horizontal should be 13 °, in particular between 15 ° -20 ° and preferably 17 °.
  • the angle of the second outlet channels to the horizontal should be 20 °, in particular between 25 ° -45 ° and preferably 32 °.
  • the invention further relates to a urinal for a sanitary facility of the type described above, comprising a basin area and an outlet adjoining this, which has an upwardly extending leg and a side extending leg. It is characterized by the fact that a fastening receptacle for a flushing nozzle, via which flushing water can be flushed into the basin area under pressure, as well as an integrated flushing water channel running externally to the basin area and opening into the outlet, via the flushing water for refilling the suction siphon to be connected with flushing water after completion the suction process can be supplied, is provided.
  • the integrated flushing water channel preferably ends in the horizontal leg of the outlet.
  • means for delaying the inflow of the flushing water into the suction siphon can be provided in the flushing water channel, and / or the flushing water channel can have a length and / or geometry ensuring a delayed flushing water inflow.
  • one or more flow obstacles can be provided in the flushing water channel, and / or that the flow cross-section of the flow channel changes over its length and / or that the flushing water channel branches into two or more channel sections that converge again, and / or that the flushing water channel is a - or wound several times between the flushing water inlet and the flushing water outlet.
  • the vertical leg of the outlet (5) should have a length of 5-12 cm and a cross-sectional area of 8-14 cm 2 .
  • the invention further relates to a flushing nozzle for a sanitary facility of the type described above, comprising a water connection pipe and a nozzle head connected to it, the nozzle head having at least one outlet channel.
  • the flushing nozzle is characterized in that a flushing water outlet designed as a radial bore or as a radially protruding connection piece is provided on the water connection pipe.
  • the flushing head can have two first outlet channels that run on opposite sides of the flushing head and at an angle to the horizontal, two second outlet channels that run on both sides and at an angle equal to or greater than that of the first outlet channels to the horizontal, and a central one Having outlet which is arranged between the two second outlets.
  • the first and second outlet channels can have a common inlet and can be separated by a partition.
  • the angle of the first outlet channels to the horizontal should be ⁇ 13 °, in particular between 15 ° - 20 ° and preferably 17 °, while the angle of the second outlet channels to the horizontal should be ⁇ 20 °, and in particular between 25 ° - 45 ° and preferably Should be 32 °.
  • the corresponding inclination, in particular of the first outlet channels avoids splashing or spilling over, especially at the front of the urinal, when the water flows out of the nozzle under pressure. This is because the rinsing water emerges from the first outlet channels with an outflow direction that is more strongly sloping downwards.
  • the Fig. 1 and 2 show a sanitary facility 1 according to the invention, comprising a urinal 2 and a suction siphon 3 connected to the urinal.
  • the urinal has a basin area 4 to which an outlet 5 is connected (see also FIG Fig. 3 and 5 ), whereby the exit 5, in relation to the assembly position of the urinal, has an upwardly extending, vertical leg 6 which is open towards the pelvic area 4, and a horizontal leg 7 which adjoins the vertical leg 6 and extends to the side.
  • the outlet 5 is formed via corresponding channel-like sections on the part of the ceramic urinal 2, the section forming the horizontal leg 7 being formed as a connecting piece.
  • the suction siphon 3 is connected on the horizontal legs 7 or the connecting piece forming it, see Fig. 5 .
  • the suction siphon 3 itself has a central connection section 8, which is followed by a helically wound section 9, which then merges into the siphon outlet 10 via a branch that slopes downwards.
  • a flushing nozzle 11 is arranged on the urinal 2, which is arranged in a bore 12 in the rear wall 13 of the urinal 2.
  • the flushing nozzle 11 has a water connection pipe 14 which emerges from the rear wall 13 and has a threaded section 15 onto which on the one hand a fastening nut can be screwed, but on the other hand a flushing water supply line can also be connected.
  • the nozzle head 16 of the rinsing nozzle 11 is located in the basin area 4 and flushes the rinsing water into the basin area 4 at a sufficiently high pressure in order to clean it completely.
  • the rinsing water runs into the outlet 5, from where it runs into the suction siphon 3 and fills it continuously, just as the outlet 5 fills continuously. If the horizontal limb 7 is full, the water column in the vertical limb 6 rises until it reaches a corresponding level 17, which, see the double arrow P in FIG Figure 5 , is slightly higher than the maximum filling level in the suction siphon 3.
  • the outlet 5 is consequently sucked out relatively quickly, with the rinsing water supply to the rinsing nozzle 11 being regulated in such a way that, moreover, in order to save rinsing water the supply is stopped shortly after the suction process has started. Since there is no longer any rinsing water and, due to the high flow velocity, there is almost no rinsing water in the basin area 4 that would run, the negative pressure collapses relatively quickly when air is sucked in via the outlet 5.
  • a flushing water channel 18 is formed in the sanitary device 1 according to the invention, which is an integral part of the urinal 1 here.
  • This rinsing water channel 18 extends from the area of the bore 12 in the rear wall 13 to the outlet 5 or the horizontal leg 7, where it opens.
  • a corresponding flushing water outlet is formed on the water connection pipe 14, via which the supplied flushing water runs into the flushing water channel 18 when flushing water is fed to the flushing nozzle 11.
  • This amount of flushing water is consequently "branched off", that is to say that only a certain part of the total amount of flushing water is flushed via the nozzle head 16 into the basin area 4, while a second part flows into the flushing water channel 18.
  • some rinsing water runs out of the rinsing water channel 18 also into the outlet 5 and, as long as the suction process is active, is also sucked off with the rinsing water sucked off from the basin area 4.
  • the flushing water channel 18 is designed in such a way, which will be discussed below, that during the duration of the flushing water supply, more water is supplied than is draining, so that the flushing water channel is at least partially filled and a sufficient amount of flushing water from the flushing water channel is still available after the flushing water supply has ended 18 runs into the outlet 5 or the horizontal leg 7 when no more water runs from the basin area 4. This Water running from the rinsing water channel 18 then runs into the suction siphon 3, partially fills it and thus forms the odor trap.
  • a ceramic component 20 attached and hinged to the back 19 of the urinal 2, which is used to form the flushing water channel 18.
  • This ceramic component 20 is quasi-shell-shaped, has a flushing channel structure and, in connection with the rear wall 13, delimits the flushing water channel 18. It can be seen that the ceramic component 20 is designed to vary geometrically in order to form delaying means that delay the flow of the flushing water so that the flushing water channel is on the one hand can fill during the water supply and on the other hand the water drains delayed. It has an upper, quasi-round section 21 in which two depressions 22 are formed, which serve as flow obstacles. This round section 22 is adjoined by a section 23 with a greatly reduced cross section and slightly meandering shape, which then opens into the horizontal leg 7.
  • FIG Fig. 4 This leads to a cross-sectional geometry of the flushing water channel 18, as in FIG Fig. 4 is shown.
  • the flushing water that enters the chamber-shaped flushing water channel 18 from the opening to be described in the water connection pipe 14 runs downward from there, whereby it must pass the flow obstacles 24, formed by the depressions 22, from where it then enters the meander-shaped , narrow channel section, which is also a little constricted at the upper end.
  • the flushing water channel 18 is at least partially filled.
  • the flow obstacles 24 as well as the meandering ducting in the duct section 23 as well as, for example, the strong cross-sectional constriction in the duct section 25 thus represent delay devices which only allow the flushing water to flow out with a delay, i.e. the flushing water either has to flow around obstacles and consequently the flow path becomes longer , or due to the very narrow cross section in the channel section 25, or due to the meandering channel shape, in turn, has to cover a longer flow path.
  • this configuration of the flow channel 18 allows the after-running of the flushing water to be delayed after the general flushing water supply has ended, in order to ensure that the siphon 3 is refilled.

  • the flushing water channel 18 is also shown for the first time, which, as it were, seen from the front, runs behind the vertical leg of the outlet 5. Compared to the cross section of the vertical leg 6, the flushing water channel 18 is significantly smaller, for example having a width of approx. 25 mm and a length of approx. 5 mm.

  • FIG. 13 shows the sanitary device 1 according to Fig. 13 a channel component 38 which is arranged on the urinal 2, which channel component 38 is designed in the form of a water tank 40.
  • This is again in the example shown connected to a corresponding connection piece 36 on the water connection pipe 14 and connected via a connection piece 41 to the connection piece of the urinal 2 forming the horizontal leg 7 of the outlet 5, so it opens here directly into the outlet 5.
  • the water tank 40 is provided with a large number of individual flow obstacles 42 in the form of deflecting wall sections to form a relatively long flow path, so that a relatively long flow path results and, in turn, a sufficient amount of flushing water is still in the water tank 40 and thus in the flushing water channel 18 even after the flushing water supply has ended that can continue to run to form the odor trap.
  • the water tank 40 is preferably a simple plastic component, as is the line 39, so that elements that can be produced at low cost can be installed in a simple manner.
