Method and device for saving water used for toilets.

The invention "relates to a method and an apparatus for Saving water used in toilets.

Human excrement in toilet bowls today is generally flushed away from them via a drainage pipe into a sewer system or an individual fecal matter. I ¹ However, a relatively large amount of water is required for flushing the excrement through the port, which is one third of the water required for each. Household and thus makes up a significant part of total water consumption.

On the other hand, the available water sources for the supply of tap water are limited, and it is getting worse from year to year Year more difficult to channel water from rivers or lakes into cities. Therefore, water supply is becoming more and more difficult, and the demand in urban areas can hardly be met.

409837/0242

Under these conditions, "a program is under development, 'the to the use of regenerated water for toilet flushing, sprinkling systems and for washing vehicles should lead. However, this program has not yet been implemented and regenerated water is not yet available. Therefore, pure tap water is used in normal households for washing clothes, for cooking food in the kitchen and for used the body wash in the bathroom. The amount of water used for these purposes "is about half the total water requirement every household.

The amount of water used by households has increased in proportion to the prevalence of water toilets in recent years increased, and the administrations are increasingly concerned with the construction of new Viasserwerke and new sewer systems. This has in the In recent years there has been a demand for a new type of toilet system reinforced, which allows saving the tap water when used as water for toilets, but a sufficient one provides a large amount of water for port rinsing of the excrement into the sewer system, with water other than pure water Tap water should be used.

A foam containing flush toilet that forms part of the invention is extremely hygienic and requires a very small amount of water, as the drainage of the excrement from the bowl is caused by the foam and the odor is suppressed because the excrement becomes embedded in the foam. However, there is a disadvantage associated with this type of toilet. A pipe that connects the bowl to the sewer system, must be 20 ° to 25 ° or more in relation to the horizontal

,, 'tends to be. This is possible when the toilet is near the Main channel or at a sufficient height above the main channel. However, if this is not the pail then a foam toilet is needed replaced by another toilet, as the drainpipe cannot be inclined by 20 ° to 25 °.

The invention is to provide a method and a Device for saving tap water directed that

409837/0242

2347U0

from the point of view of hygiene and odor prevention is equivalent to conventional flush toilets.

The method according to the invention for saving water used for toilets is characterized in that the waste water collects from kitchens, bathrooms and sinks and a waste water supply device supplies that you collect the excrement in a foam containing toilet bowl and with Foam surrounds and discharges into the area of the sewage supply device, and that the excrement from this area after accumulation flushes away a predetermined amount of waste water at intervals.

The device according to the invention for carrying out this method is characterized by a foam-containing toilet seat equipped with a surfactant for the continuous production of foam impregnated mat is lined, by a knee then .an the lower end of the toilet bowl with the same lining, by a Series of pipes connected to the knee for the discharge of the excrement, through a downstream one, into a drainage pipe transferring odor trap and a waste water supply device, which has a pivotable container for receiving and for collecting waste water from a kitchen, a bathroom and a sink and arranged in the area of the odor trap is, wherein the container of the sewage supply device is designed such that its center of gravity moves laterally with an increase in the amount of waste water in the container and finally über die Senkrechte.by the hinge adjoins when the content has exceeded a predetermined height, so that the container suddenly tips over for emptying, and that the center of gravity after emptying the container in the starting position tilts back

The container of the waste water supply device is preferably supported by a holder and opposite to the surrounding one Protected bottom and has an opening at the top for inlet and discharge of the waste water.

The waste water from the kitchen, bathroom or collected in a sink. The wastewater contains dirt and rubbish without the risk of clogging enter or that sewage overflows. Through, the sudden Overturning the container, the excrement from the foam-containing toilet bowl into the sewer system or a single one Sewer pit flushed. Since the sudden overturning of the container at a predetermined filling level is important variable counterweights provided for precise adjustment of the center of gravity. There is also a detachable fastening device provided at the bottom of the pivoting container, which allows a long service life under the present conditions ·

The apparatus for carrying out the method according to the invention comprises according to Pig. 1 a foam-containing toilet B with a foam-containing knee A in connection with the toilet, a waste water supply device C and a drain pipe D in connection with this device. The device is constructed in such a way that the foam-containing toilet B is above and the waste water supply device C is below the foam-containing knee A, and that the waste water supply device G is connected to the lower end of a pipe string 5, 5 ¹ »5" A sewer pipe 1 is connected to the sewage supply device C, and this is connected to the drain pipe D via a knee or an odor trap 2 at its lower end.

A bowl 3 of the foam containing flush toilet B, the foam containing knee A and a rubber strainer 4 are for foam sealing between the knee A and the drain pipes 5, 5 ^f , 5 "for the excrement on the inner surface with a Mat lining 6 coated with an aqueous solution of a

surfactant that is soaked continuously. Foam produced. A significant amount of foam is produced when a button is pressed after the excrement 7 has been discharged into the bowl is printed so that the bowl is cleaned and the excrement 7 pushed down by the foam while they. are surrounded by the foam.

The foam dissolves over time, so that the pipes 5, 5, ¹ , 5 "are never clogged by foam. Some of the foam can, however, remain in the water 8 in the odor trap 2. The amount of foam used to seal the foam formed foam

• ζ

carries 2 to 3 cmr / min (3 to 4 l / day), based on an aqueous Surfactant solution.

The wastewater supply device G is used to receive the wastewater, the dirt and waste contains, through the sewer line 1 from the kitchen or from a sink, and the feeder C collects the wastewater until a certain amount is reached. At that moment the total amount of wastewater collected will be dispensed at intervals to wash away the excrement 7 from the bowl 3.

The waste water supply device G comprises a pivotably supported, waterproof container 10 for collecting the sewage 21 and for discharging this sewage, and a holder 17 for supporting of the container 10 and to protect the container from the surrounding soil.

The container 10 is arranged watertight and tiltable and has an opening 9 for receiving and discharging the waste water 21 as well a joint 12 for supporting the container 10. This joint 12 is in Pig. 1 and 3 shown as a knife edge.

The degree of tilting of the container and the position of the counterweights 18 are set so that when the container is in the positions of Pig. 4A to 4Ξ, the joint 12 is in a position below the centers of gravity Ga to Ge. When the amount of waste water 21

409837/0242

2347U0

exceeds a predetermined height L shown in Fig. 4C is, the center of gravity Gc moves to the left in the figure and is thus outside the joint 12. When the container 10 is empty is (Fig. 4A) or sewage 21 at a level below the predetermined Contains height Ii (Fig. 4B) or for discharging the sewage 21 and tipping over for emptying (Fig. 4E), the center of gravity moves " to the right of the hinge 12 in the figure.

In other words, the container 10 is in an unstable one Equilibrium because the center of gravity is shifted with the increase or decrease in the amount of the collected sewage 21. The behavior of the container 10 when the waste water 21 is gradually supplied to the container through the opening 9 is now intended will be described with reference to Figs. 4A to 4E.

When the container 10 is empty, it stands stable in the inclined position with the wall 11 forming the bottom and in contact is held with a recess of the holder 17, as shown in FIG. 4A. When the waste water 21 is passed into the container 10 is, but the height of the sewage is below the predetermined height Ii, v. the center of gravity moves from the location. Ga too Ge position or closer to the hinge 12, but while the container remains in the inclined position without tipping over. When the content of the container 10 increases and exceeds the predetermined height L, as shown in FIG. 40, or when the Container 10 errr through a large amount of sewage 21 that is suddenly discharged into the container in a short period of time, the center of gravity Gc moves to the left of the hinge, and the container 10 tips over in the direction opposite to the wall 11, as shown in FIG. 4D, so that the sewage 21 and the majority of the dirt and waste 20 are automatically washed away through the opening 9.

When the container 10 has emptied itself, the center of gravity moves to position Ge and the container becomes inclined Tilted back starting position. The same process is then repeated while the waste water 21 enters the container 10 is introduced and the amount of waste water increases, so that

409837/0242

the wastewater to rinse away the excrement "released at intervals will.

The container 10 is supported in the holder 17, which comprises an outlet 14 and a lid 17 *, in which the sewage inlet 15 is formed. The holder 17 has a bottom surface 13 which is inclined in the direction of the outlet 14, see above that the draining waste water of the container 10 can flow off over the floor surface.

So that the container 10 does not tip over forward when the amount of waste water contained in it is below a predetermined Height, and so that this is not the pail even in the event of impacts on the container, this container is constructed in such a way that that it is normally in an inclined position with the center of gravity to the right of the joint 12 or on the side the wall 11 is when the container is empty or contains a small amount of sewage. As mentioned earlier, counterweights can be used 18 or the like can be provided and prevent the container 10 from tipping over prematurely. Preferably is the bottom surface 13 V-shaped in cross section, so that sticking of the opening 9 to the bottom surface due to surface tension of the water is prevented.

Although the container 10 has a very simple structure, it dispenses all of its contents without holding back a drop of water, since the bottom wall 11 and the side surface represent a strongly inclined and a slightly inclined surface, which are continuous merge. Almost no dirt and waste residues from the wastewater remain in the container 10. Even if some scraps are left behind, the next one will Process washed away and never linger for too long.

The excrement 7 reaching the bowl 3 move by gravity in the direction of the outlet 14 or the bottom surface 13 of the sewage supply device C and into the drain pipe D or the odor trap 2, through the pipes 5 >> 5 ¹ and 5 "and remain there temporarily The excrement 7 temporarily accumulated there is washed away by the wastewater 21, which

409837/0242

is abruptly fed from the waste water supply device C, and then pass through the drain pipe D with the odor trap 2 into a collecting channel or a single waste water basin.

The amount of water used for flushing the toilet at the time is 35 »7 i ° äes total water consumption of each household. The ones in everyone. Household amount of water used for washing clothes and the like, for personal wash in the bathroom and in the bath and for cooking food in the kitchen is 17.5 $ »4> 6 ^ i and 27.5 ° of the total water consumption. If this water were then used as waste water 21 within the meaning of the invention, the amount would be greater than that of the pure water previously used to flush the toilets. When rainwater is available, the amount of water available to wash away the excrement is more than double the amount of water previously used for this purpose. ,

The amount of wastewater available in each household 21 can't be big enough. The more water available stands the better. There are also no problems if the emptying of the container 10 does not begin with the delivery of Excrement in the toilet bowl 3 collapses and not every time excrement are flushed away when they are in the Toilet bowl. As the excrement is carried out by an aqueous solution of the surface-active agent, which acts as a lubricant By being moistened, they do not clog the drain and are released evenly. Small reliever particles become further divided and partially dissolved and do not adhere to the parts of the device.

From the above description it can be seen that the inventive The method can be carried out with the help of a device that is next to a foam-containing toilet B and a conventional drain a waste water supply device C with very simple structure included. The process leads to the saving of "pure tap water suitable for drinking, because the excrement getting into the toilet bowl through the sewage from the kitchen and the bathroom without the use of pure Tap water can be flushed away. A spread of the

409837/0242

method according to the invention and the device according to the invention would reduce the burden on the waterworks operated by the local administrations and introduce a make second tap water system unnecessary for households. In addition, the invention offers the advantage of a hygienic ' Toilet operation even with limited water supply

The presence of dirt and debris in the sewage 21 hinders the process of flushing away the excrement through the sewage supply device C does not, and there is no risk of that the device C is clogged or leaking. Since the amount of water used to rinse away the excrement according to the invention larger than conventional procedures, and because the drain on the inner surface with a surface active agent. If the lubrication effect is coated, the entire system does not clog.

The odor trap 2 in the drain pipe D and the rubber strainer 4 in the foam-containing knee A preclude the generation of sewage gases, contribute to the reduction of odor at and prevent the development of worms. The foam containing toilet B continuously carries 2 to 3 cm of water per Minute to the odor trap 2 in foam form, even when it is not in use, so that the water 8 in the Odor trap 2 is never lost through evaporation.

The device according to the invention is not only very simple, but the sewage supply device C also requires no valves, closures or joints, so that operational errors are excluded »

In some households, a toilet containing foam is in use in combination with a cesspool. the Invention has the advantage that such households can be connected to a flushing system when a main channel in their proximity is carried out by additionally installing some facilities. It is also a key property of foam containing toilets that the toilet bowl is always clean and looks better than conventional flush toilets.

40983 7/0242

Experiments have shown that the noises "when the Container 10 and tilting back into the starting position are very low. The noise is less than the "noise produced by flush toilets with the water tank underneath.

The height of the container 10 or the gradient of the water in relation to the drain pipe D are fixed within certain limits, so that Sewage from the kitchen or the like can be taken over smoothly. However, since the sewage supply device C does not have valve seats or locking seats and since the drainage system has only slight bends, there is only a slight desire for height of the water and the water pressure can be used effectively. The odor trap has sufficient cleaning and cleaning properties Siphon effect as a result and the aqueous solution of the surface-active Means in the toilet bowl and the knee for producing a foam is in the dissolved state and is for Destruction of microorganisms, especially suitable in the sewage system. The method according to the invention therefore offers the additional advantage that the total amount of wastewater in the sewer system is reduced and the load on this system is reduced

ti

A modified embodiment of the fiction, contemporary wastewater supply Facility C shall now be referred to with reference to Pig. 2 described will. The device for carrying out the method according to the invention for saving water in flush toilets according to FIG. 2 comprises a toilet B containing foam with a foam containing knee A in connection with the toilet, the waste water supply device C and that with this connected drain pipe D, the device is constructed such that the foam-containing toilet B is above and the sewage supply device G below the foam containing knee an- • is arranged, wherein the sewer line 1 is arranged between the toilet B and the waste water supply device 0. The drain pipe D with the odor trap 2 is attached in the lower area of the waste water supply device C. In this embodiment of the waste water supply device C, the excrement 7 are together with the wastewater 21 of the kitchen etc. into the container 10

409837/02 42

23A7U0

heads, which is waterproof and pivotable as referenced on Pig. 1 "was described, and held in the holder pivotably and through this relative to the surrounding Ground is protected. The container 10 has an opening 9 for receiving and discharging the waste water 21 and the excrement 7 and is supported in the joint 12.

Like the container in Pig. 1 is the pig's container. 2 arranged in unstable equilibrium, since the center of gravity is in Depending on the increase or decrease in the amount of sewage

21 and the excrement 7 in the container moves as it is below

Reference to Pig. 4A to 4E discussed above.

The sewage 21 and the excrement 7 introduced into the container 10 through the opening 9 behave in the same way like the sewage 21 in the container 10 of the Pig. 1.

The holder 17 for supporting the container 10 has an excrement inlet 16 next to the outlet 14, the sewage inlet 15 and a working opening 19. A work opening lid

22 is located on the working opening 19 in a frame 23. The bottom surface 13 is inclined in the direction of the outlet 14 in the holder 17 is formed and conducts the waste water 21 containing the excrement, which is via the container 10 in the holder 17 exits, from.

Another modified embodiment of the invention Wastewater supply device O, which is an improvement over the Represents basic form, shall now with reference to Pig. 5. As previously mentioned, the sewage supply means comprises C basically a pivotably supported container 10, which is arranged in an inclined position and for Absorption of the waste water 21 from the kitchen, the bathroom, the sink, etc. (and the excrement 7 in some Pallen) is used. if the amount of waste water 21 (and the excrement 7) increases or decreases, the center of gravity of the container shifts, so that this tips over at intervals and then returned to the inclined position. The sewage supply device C further comprises a bracket 17 for supporting the container

409837 / 02-42

2347U0

10 and to protect the container from the surrounding ground. When the amount of water and excrement is below 21 a "certain height (the amount of water to! flush away the excrement is 12 to 14 1), the container 10 does not tip over. However, if the amount exceeds the predetermined amount, the container 10 tips over quickly forward and washes the excrement 7 together with a relatively large amount of waste water 21 away.

The relatively large amount of waste water 21 including the excrement 7 moves suddenly and 'quickly in one go after tipping over of the container 10 in the direction of the outlet 14 (diameter about 100 mm) like a uniform wave. Therefore there is the possibility that part of the waste water 21 is thrown back from the end wall 24 of the holder 17 and flows back, or that a Part of the waste water 21 remains in the holder 17 without all of the waste water being discharged at the same time.

The holder 17 has a bottom 17 ″, which was previously described embodiments with the outlet 14 in an approximately straight line with a slight drop in the direction of the outlet 14 was connected. Therefore, when the sewage 21 flows back or in the bracket 17 remains, it moves all the way back to a point on the floor 17 ″, which is to the right of the joint 12 or the hinge support 25 of the container 10 is located. Since that Waste water is gradually discharged through the outlet 14, the excrement, dirt and debris on the joint or the joint support 25 or on the bottom 17 ″ of the holder 17 are deposited together with cooking oil and the like the effectiveness of the waste water supply device C is reduced and the system is disadvantageous from the hygienic point of view.

The container 10 tilts forward until part of its front wall touches the bottom 17 ″ of the holder 17. Therefore, the flowing back Return waste water to the container 10 and prevent the container 10 from tipping back into the original position. Consequently the wastewater 21 is not collected in the container 10, but discharged without a purpose ...

409837/0242

Now the shape of the wastewater feed device C according to Eig. 5 ", that is to say, these disadvantages of the basic form switched off v / earth.

The pivotable container 10 according to Pig. 5 is supported by the holder 17, which the container 10 relative to the surrounding Soil-protects. In addition to the working opening 19, the bottom 17 "and the outlet 14 for the excrement an end wall 24 is provided on the holder 17, which is connected to the pipe 5 'and the sewage inlet 15 communicates on the top and side wall.

The pivotable container 10 is in the hinge 12 on its underside pivotally supported, and the bracket 17 comprises a joint support 25 for supporting the joint 12 on the bottom 17 "of the Container 17. The bottom 17 "is offset in an area to the left of the joint support 25 in FIG. 5, so that a Water sump 26 arises, which opens to outlet 14.

The container 10 of FIG. 5 operates in the same way as the other embodiments of the container. The sewage is introduced into the container 10 through the sewage inlet 15 ", while the excrement 7 enter the container through the pipe 5 ^1. When the amount of the sewage 21 and the excrement 7 in the container 10 increase, the center of gravity shifts of the container 10 after

left, until the container suddenly tips forward and is emptied. When the contents of the container 10 have been dispensed, · the container 10 immediately tilts back into the starting position and there again takes on waste water 21 and excrement 7. To this Way, the container 10 intermittently gives both waste water 21 and excrement 7 to the main sewer line through the Outlet 14 and the odor trap 2 from. The holder 17 has the same effect as in the other exemplary embodiments.

The water sump 26 has such a volume that the water flowing back at the outlet 14 does not pass over the water sump 26 steps out. In the embodiment shown, the water sump 26 is designed essentially as a rectangular parallelepiped and has a volume of about 7.5 1

409837/0242

The holder 17 according to Pig. 5 differs from the other brackets by the water sump 26. Although the water sump 26 is of simple construction, it prevents the water from flowing back onto the bottom 17 ″ of the holder 17 ″, even if a Part of the sewage and excrement remain in the holder 17 or collide against the end wall 24 and flow back, since all of the wastewater and excrement cannot exit through outlet 14 at once. All sewage and all Excrement that does not exit through the outlet 14 collects in the water sump 26, so that adhesion of Dirt or debris on the joint 12 or the joint support 25 as well as a deposit of edible fats or the like on the Floor 17 "can be prevented.

When the container 10 tips forward, its front edge is above the level of the outlet 14, so that the sewage and the Excrement does not flow back into the container, which is why it can quickly return to its starting position. As mentioned, a rope of sewage and excrement remains in the water swamp 26 without exiting through outlet 14. The dirt and waste mix with the sewage and in a suitable way remain in suspension in this wastewater in the water sump 26, so that the dirt and waste are washed away with the wastewater without lagging behind. Even if edible fats and the like deposit on the bottom of the water sump 26, can these can easily be removed through the working opening 19.

The following are devices for controlling the balance of the sewage supply device C with reference to Pig. 6 and 7 will be described.

As mentioned, the wastewater from the kitchen, the bathroom and the bathtub and the excrement from the foam are contained toilet initiated into the pivoted container, and the center of gravity of the container shifts with increasing Contents until the container suddenly tips over forwards and is emptied and then after emptying into the starting position tilts back. In this way the container will tilt back and forth

409837/0242

2347U0-

at intervals and collects dirt and debris along with it Excrement and releases it into the sewer system.

In order to reduce the production costs of the container, normal processing must be accepted so that the container can be unevenly thick. It is therefore necessary to provide the container with balancing devices so that this reliably tilts forward when the waste water in the container reaches a predetermined height L, and then immediately into the starting position returns. For this purpose, counterweights can be used, preferably with the inclined rearward Wall of the container to be connected. Embodiments of the compensating devices will be described with reference to Figs. In the Pig. 6 is a vessel 27 with an approximately L-shaped cross section and approximately trapezoidal Side walls provided on opposite sides with an open top. The vessel 27 is on the lower wall 11 of the container 10 attached and forms with this a substantially triangular space 29 which is open at the top and lies between a wall of the vessel 27 and the inclined rear wall 28 of the container 10.

The compensation takes place with the help of weights 30, 30 'with suitable Compounds that are introduced into the space 29 after the container 10 is via the joint 12 on the bottom 17 ″ of the holder 17 is mounted in the hinge bracket 25, and then water is gradually poured into the container 10. When the container 10 after tips over in front as long as the water has not yet reached the predetermined height L, the number of weights 30, 30 'is increased. If the container 10 does not tip over forward when the water has reached the predetermined level L, the number becomes of weights decreased. When the weights in the space 29 have reached an optimum value, a resin 31 is poured into the space 29 poured and fills the spaces between the weights and covers them.

The weight of the resin poured into the space 29 is first determined and from the weight of the weights 30, 30 ^! withdrawn

409837/0242

gen. In this embodiment "consist of the containers 10 and the The vessel 27 is made of reinforced plastic, and the resin 31 is an unsaturated polyester resin. The weights 30, 30 '"consist of Iron.

This structure eliminates the need to "attach weights" to the sloping rear wall 28 of the container 10, if so is required. According to the invention, the weights 30, 30 ' be embedded in the room 29. The resin 31 filled in the space 29 ensures that the vessel 27 is bonded to the container 10 with strong adhesion.

The weights 30, 30 'can on the other hand on the rear wall 28 with With the help of screws or rivets. When the weights however, made of iron, which has a relatively high specific gravity and is cheap, they can corrode. Therefore, according to the invention, the weights are embedded in resin, so that there is no risk of corrosion.

The vessel 27 can be replaced by a vessel 32 according to Pig. 7 are replaced, which is approximately triangular and open at the top.

The vessel 32 is attached to the sloping rear wall 28 of the container 10 and acts in the same way as the vessel 27 except for that here a very good connection between the container 10 and the vessel 32 is not made when resin is poured into the vessel will.

The following are the fastening devices for the sewage supply device 0 can be described. As explained above, the pivoting container tilts intermittently for emptying and returns to the starting position when the Content is submitted. Therefore, a significant impact force is applied to the container as it tilts back and forth, so that fasteners are required. It has been proposed to use axes of rotation supported in bearings. However, the bearings are damaged by oils, fats and food residues, which are contained in the sewage of the kitchen, so

409837/0242

that their lifespan is very short. Besides, in this case the container difficult to access and difficult to remove from the right-angled position when monitoring or repairing shall be. These disadvantages are eliminated according to the invention.

According to. Fig. 8 are joints 12, 12 * on the underside of the floor of the pivotable container 10 while articulated supports 25, 25 'to support the joints 12, 12' on the surface of the The bottom of the bracket 17 are attached. Rods, 33, 33 'more suitable Length and suitable diameter protrude outwardly from the outer sides 36, 36 · of the joints 12, 12 ·. Slightly curved Plates 34, 34 'are adhered or screwed or riveted to the upper outer sides of the hinge supports 25, 25 'connected. The slightly curved plates 34, 34 'are arranged symmetrically and iron a cutout in a position offset from the central position of the inner surface of each plate 34, 34 "in the direction of the outlet 14, the central region of each plate 34, 34 'forming an arc.

If the position of the cutout 35 in the curved plates 34, 34 is selected as 'suitable', the forward and backward movements are of the pivotable container 10 in the range of 40 ° to 45 °, so that the joints 12, 12 'by the joint supports 25, 25' securely supported and cannot be earthed separately from them.

The mode of operation of this fastening device is as follows. When the sewage 21 and the excrement 7 in the pivotable Container 10 are below the predetermined height L, the container is standing 10 in its inclined position and does not tip over because the container 10, the sewage 21 and the excrement 7 are the joints 12, 12 'press tightly against the joint brackets 25, 25'.

When the amount of sewage '21 and excrement 7 in the container 10 exceeds the predetermined level L *, the container 10 suddenly tips over and empties through the outlet 14. As soon as the contents of the container 10 have leaked, the container "tilts" quickly If the container 10 were not held in place by the fasteners, point a in Pig directions a and ^{1 b!} according to Pig. 1OA and exposed 1Ob. thus would the joints 12, 12 to strive ^f to jump out of the hinge supports 25, 25 ^f, such that the container could be shifted to the right or left.

If the container 10 is provided with fastening devices, the hinges 12, 12 * are prevented from jumping out, since the upward movement of the rods 33, 33 ^! protruding from the outer surfaces 36, 36 'of the hinges 12, 12' is prevented by the curved plates 34, 34 ', as in Pig. 11A and 11B is shown. At the same time right and left movements of the container 10 are prevented by the lateral surfaces 36, 36 'of the hinges 12, 12 * and the slightly curved plates 34, 34', so that the displacement of the container is prevented.

When cleaning or checking the holder 17, the container 10 is ^{pulled out through the working opening 19 in the direction of an arrow C 1} in FIG. This enables the rods 33, 33 'to be pulled out through the cutout 35 in the curved plates 34, 34' and to remove the container 10 from its position.

After cleaning or checking, the container can be returned to its original position with the hinges 12, 12 · get onto the joint supports 25, 25 'by the previously mentioned Operation is carried out in reverse. When the container 10 after attachment in the correct position to the left or is shifted to the right and does not move, it is in the correct position. It is therefore not necessary look into the working opening for this purpose.

The fastening device according to the invention allows a reliable Fixing of the container in the correct position without shifting from the normal position. The location is not the influences exposed to dirt and debris in the sewage. The fastening device is cheap and allows the To remove the container from its position when the container holder 17 is to be cleaned or checked.

In the following, the application of the invention to a multi-storey Buildings, such as an office building that uses a large amount of tap water. According to the invention can tap water by using foam-containing toilets instead of flush toilets and urinals and by port-flushing the excrement into the sewer system using waste water from a sink, a boiling water station or a cleaning water tank on every floor of the building can be saved.

The population increase in the big cities has become a necessity an intensive use of building land and thus a demand for multi-storey buildings. So has The demand for tap water for use in flush toilets, to operate air conditioning systems and for other uses increased. The demand for water is about to exceed the supply and there is There is a risk that water consumption will have to be restricted and that wastewater reuse will become the rule «,

2347H0

However, it is not possible to limit water consumption without the population taking the situation into account. the Returning waste water for reuse requires a third water system in the building in addition to the supply system and the drainage system and thus extremely high costs and an extensive installation time. The construction of a new water system, serving the needs of a large population requires considerable time.

In view of this situation, the application of the invention is to multi-storey buildings in which numerous business offices are housed, meaningful. The tendency to water closets, sinks, hot water stations and more water consumers summarizing each floor of the building separately in a certain section facilitates the application of the invention on such a building.

According to the invention, toilets lined with foam are used instead of conventional flush toilets, and push-button urinals are being used in place of a conventional one automatically flushing latrine system, and the excrement of the foam-containing toilets and urinals are collected in transverse excrement pipes on each floor. A sewage supply device for flushing The excrement is provided on each floor and placed in a location where the facility is easy to monitor and repair is accessible and effective sealing can be carried out, for example in a corner on ■ the ceiling of a toilet. The pivotably supported container of each wastewater supply device takes the wastewater from the overlying donkey And empties automatically at intervals, flushing those embedded in foam in one go Excrement in the transverse excrement duct in a vertical excrement pipe. In this way, the Excrement on each floor is flushed into the sewer system by removing the waste water from boiling water stations, wash basins and like of the different floors is used. If the sewage feeder is in a corner on the ceiling of a

Toilets are provided on each floor, creating a water gradient in the device in relation to the transverse excrement line, so that the waste water from the boiling water station, the cleaning water tank, the sink and the like of the floor immediately above can be used for port rinsing of the excrement.

The invention therefore makes it possible to have water in large buildings in large cities and their surroundings with a complete sewer system Saving by using wastewater for port rinsing of the excrement of the Stoclewerk immediately below and foam containing toilets with very low water consumption instead of conventional flush toilets with relatively high water consumption can be used. The embodiments are now intended to referring to Pig. 12 to 20 will be explained. Pig. Fig. 12 shows a plan view of a water using portion one floor of a multi-storey building in which urinals, sinks, toilets, boiling water stations and Cleaning water tanks are concentrated. In general the arrangement is the same on all floors. Located in the Pigur the wash basins and "boiling water" stations on the floor immediately above the toilets and urinals.

The excrement of the foam-containing women's toilets 38 'are conducted into a transverse excrement line 45 via inclined pipes 38 "which ^{connect the women's toilets 38 f} to the excrement line 45 similar inclined tubes 38 "headed. The excrement are combined in the excrement line 45 and flow through this line due to the lubricating effect of the foam into a vertical excrement line 46 which extends from top to bottom through the building.

The urine of the urinals 39 is through a urine line 39 'in the upper branches of the transverse excrement line 45, with which the pipes of the ladies room 38 'are connected are. On the other hand, wastewater is fed to a wastewater supply device 47 for port rinsing of the excrement with a suitable capacity

that was attached to the ceiling of the toilet in one corner is. The supply line is via a line 44 from the men's washbasin on the floor immediately above and through another line 44 'from the ladies' washbasin 40, from the basin 41 of a hot water supply station, from a cleaning water tank 42 and a water boiler 43 of the floor above.

When the pivoted container 48 of the sewage supply device 47 of each floor is filled with the sewage at a predetermined height, the container 48 tilts automatically forward due to gravity and empties itself. The contents flow through a sewage supply line 47 'and flushes the excrement through the transverse excrement lines 45 and 45 'in one go. After the content has been released the container back to its original position so that the process is repeated at intervals.

Air supply lines can be connected to the excrement lines on any known kind be connected.

According to the invention, rainwater can be used to save water for flush toilets. For example, the inventive Device a rainwater holding tank underneath the advertising facilities on the roof of the building or in any other suitable position for receiving and storing rainwater. The rainwater collection tank is connected to the sewage supply device on each floor, so that the rainwater is used to flush the Excrement used to supplement wastewater. The arrangement does not require any special construction and can be used without significant additional Costs not only in new buildings, but also in old buildings.
