Definitions

  • the invention relates to a method for flushing toilets, in which water and air are conveyed from a pressure vessel via an outlet valve and an outlet pipe into a toilet bowl.
  • the invention further relates to a device for carrying out the method in which a pressure vessel for rinsing water and compressed air cushion located above it is connected via an inlet to a water pipe and to an air supply and can be emptied into a toilet bowl via an outlet which can be closed with an outlet valve.
  • an open box is provided as a container for the flushing water, which is either arranged directly above the toilet bowl and opens into the inlet of this toilet bowl via a short elbow, or approx. 1.20 m to 1.50 m above the toilet bowl mounted and connected to it by an irrigation pipe with an inlet bend.
  • the flushing pressure is determined by the height of the water and is comparatively low. Large amounts of water are required for hygienic operation, which vary between 9 1 and 14 1 per rinsing cycle, depending on the device type.
  • Hanging cisterns give the water a higher kinetic energy and therefore have a 10% to 15% lower water consumption than low-hanging cisterns.
  • they require major investments when installing the flushing pipe and are hardly installed anymore for aesthetic reasons.
  • Another disadvantage of these designs is the long filling time of the box of about 70 s, which does not allow repeated rinsing in rapid succession.
  • the flow of the rinsing water cannot usually be metered. Due to the design, the bowl of every dishwasher is almost completely emptied, which, together with the low pressure of the flushing jet, contributes to the very high water consumption.
  • Pressure flushers have also been known for some time, which are connected directly to a water pipe without an intermediate container and which flush with the full line pressure of approx. 4.5 bar. With these devices a high water speed and good splitting effect are achieved. The amount of water used during rinsing can be largely metered and thus kept low.
  • a disadvantage of flushing valves is that, in order to maintain a large, rapidly flowing amount of water for the entire supply lines, pipe cross sections are required which go considerably beyond the normal dimension. Furthermore, the flushing effect is influenced by the pipe cross-section and fluctuations in the line pressure.
  • a water rinsing device which also works on the injector principle. With this device, outside air is drawn in directly from the flushing pipe.
  • An upright cylindrical container is provided for the rinse water and there is an air cushion above the rinse water.
  • the injector itself is arranged within the flushing water and essentially consists of a block with a bore running axially to the container axis, which conveys water and air into the interior of the container.
  • the axial bore in the block is narrowed in the middle and this narrowing is connected to a suction bore for air via a thin channel.
  • this suction hole leads into the flushing pipe via a connecting line.
  • an injector designed in this way cannot work satisfactorily.
  • the flushing process is therefore not improved despite a high water consumption, a construction which is relatively complicated due to the holes and is also quite susceptible to faults.
  • the ball valves used do not always ensure a reliable seal and the injector used in the container is difficult to access, which makes maintenance of the device difficult.
  • the object of the invention is to provide a method for flushing the toilet with water and air which brings an optimal flushing effect with minimal water consumption and which can be carried out with a device whose pressure vessel has minimal dimensions and relatively simple and less susceptible components.
  • This object is achieved by a method of the type mentioned at the outset in that air and water are introduced at a container internal pressure of at most 3 bar and only water at more than 3 bar into a pressure cushion space of the pressure container.
  • a device for performing the method consists of a pressure tank for rinsing water and a compressed air cushion located above it, which is connected via an inlet to a water pipe and an air supply and via an outlet which can be closed with an outlet valve Toilet bowl can be emptied and is characterized in that the air-water inlet opens into an inlet in the area of the pressure cushion space of the pressure container.
  • the pressure vessel as a water reservoir can therefore be compared are kept small so that only short filling times are required even after the rinsing process.
  • the method of operation also allows a true, effective two-stage rinse, with a partial rinse in a first stage and a full rinse in a second stage.
  • the components of the device according to the invention are relatively simple and easily accessible since they are not housed in the pressure vessel.
  • the flushing device is separated from the water supply network by the intermediate pressure vessel and the air in the pressure vessel is under the pressure prevailing in the network. It forms a resilient pressure cushion and can absorb pressure surges when the dishwasher is operated. Adverse effects on the water supply network cannot occur as a result. Because of its design as a pressure vessel, the water container can be arranged in an almost jader position with respect to the toilet bowl and can have any shape, so that it is possible to build very compact devices.
  • FIG. 1 shows a water closet 1 which is equipped with the flushing device according to the invention.
  • This consists of a closed pressure vessel 2 for the rinsing water 3 and an air cushion 23 located thereon.
  • the pressure vessel 2 is spherical in the exemplary embodiment according to FIG. 1 and is arranged above the toilet bowl 4. Any other shape and position of the pressure vessel 2 is also possible, for example as an elongated cylinder, which can also be installed in the foot 5 of the water closet 1 below the toilet bowl 4.
  • FIGS. 3 to 5 Various embodiments are shown in FIGS. 3 to 5, which will be discussed further below.
  • the pressure vessel 2 is filled via an inlet 6 connected to the water supply network, which opens into the area of the pressure cushion space, for example at the top 7 of the pressure vessel 2.
  • An injector 8 is arranged in the inlet 6, through which air flows into the pressure vessel 2 together with the inflowing water flows in.
  • the injector 8 is, for example, a conventional water jet pump, the suction side 9 of which communicates with the outside air and is closed by a check valve 10. Water flowing through the injector 8 into the pressure vessel 2 creates a negative pressure on the suction side 9, by means of which the check valve 10 is opened. In this way, air is sucked into the injector 8, which mixes with the water flowing in from the inlet 6 and is conveyed into the pressure vessel 2 through an air-water inlet 6 '.
  • Disinfectant and / or odor-improving substances can also be mixed with the air in the injector 8 together with the air.
  • corresponding storage containers 58 are provided on the suction side 9 of the injector 8 between the line 57 communicating with the outside air and the injector 8, the contents of which are sucked in together with air.
  • shut-off valve 11 In the inlet 6 connected to the water supply network, a shut-off valve 11 is arranged in front of the injector 8, through which the water closet 1 is separated from the water supply network for assembly or maintenance work. Shut-off valves 11 of this type are known and customary for other types of water closets.
  • the inlet 6 always opens into an inlet 12 leading into the pressure cushion space 23, expediently at the top 7 of the pressure container 2.
  • An outlet valve 15, which is actuated to initiate the flushing process, is preferably arranged at the lowest point of the bottom 14 of the pressure vessel 2.
  • a lever 16 is used, which is gripped at a button 17 and depressed. Constructive features of a preferred embodiment of this outlet valve 15 will be described in detail below.
  • An outlet bend 18 leads from the outlet valve 15 to the water closet 1.
  • the outlet bend 18 opens into an opening 19 above the toilet bowl 4 in such a way that a water jet emerging therefrom is located in the toilet bowl 4 chen rubbish in a spout 20.
  • the outlet 20 is connected to the sewer network via a pipe 21.
  • a working cycle of the flushing device proceeds as follows. After a rinsing process, the pressure vessel 2 is empty or only partially filled. It contains a residual amount of water and air under atmospheric pressure (1 bar). Due to the line pressure in the inlet 6 of approx. 4.5 bar (normal pressure), water is therefore pressed through the injector 8 into the pressure vessel 2. The water flow on the suction side 9 of the injector 8 creates a negative pressure, the check valve 10 opening. Air is sucked in, which mixes with the inflowing water and is conveyed into the pressure vessel 2 in addition to the air already present in the pressure vessel 2. The air-water mixture generated in the injector 8 segregates in the pressure vessel 2, the air rising to the top.
  • Air and water are fed into the pressure vessel 2 until the internal pressure of the vessel has risen to a maximum of 3 bar.
  • the internal pressure rises i.e. above 3 bar
  • only water is pumped.
  • the air trapped in the pressure vessel 2 is compressed by the rising water column.
  • the difference between the line pressure in the inlet 6 and the pressure prevailing in the pressure vessel 2 decreases.
  • the water flow passing through the injector 8 slows down and the suction power decreases.
  • the negative pressure on the suction side 9 of the injector 8 collapses and the check valve 10 closes. Thereafter, water continues to flow through inlet 6 and injector 8 with a slow flow until full pressure equalization has been established.
  • the outlet valve 15 on the bottom 14 of the pressure vessel 2 is opened.
  • the pressure surges that occur during valve actuation are absorbed by the compressible air cushion 23 in the pressure vessel 2 and are not passed on to the line network.
  • the liquid water 3 stored in the pressure vessel 2 is accelerated by the pressure of the air cushion 23 and conveyed into the water closet 1 via the outlet arch 18. This achieves a high flow rate and a good splitting effect.
  • water With the pressure drop occurring in the pressure vessel 2, water immediately begins to flow in from the inlet 6, and as soon as a sufficient flow rate has been reached, the injector action also starts again.
  • the outlet valve 15 only closes when a noticeable amount of air-water mixture has subsequently flowed into the pressure vessel 2 and has exited through the outlet valve 15, since, according to the findings of an embodiment of the present invention, this air-water mixture in particular is excellent Rinsing effect.
  • FIG. 2 A preferred embodiment of an outlet valve 15 is shown in FIG. 2.
  • This outlet valve 15 allows the desired amount of rinse water to be metered in two stages. On the one hand, it is possible to carry out a partial rinse with only part of the rinsing water 3 stored in the pressure vessel 2. On the other hand, it can be almost complete Emptying the pressure vessel 2 a full flush can be triggered. Alternatively, there are options to carry out the full flush immediately or delayed by a previous partial flush.
  • the outlet valve 15 (FIG. 2) has an axially symmetrical housing 24, along the central axis of which a piston rod 25 extends.
  • the housing 24 is divided into two chambers 27, 28 by an intermediate plate 26.
  • the first chamber 27 is assigned to the water inlet side of the valve 15. It is provided with a pipe socket 29 as a valve inlet and contains a valve cap 30 with a sealing plunger 31 arranged therein, both of which are moved by means of the ebb rod 25.
  • the second chamber 28 is assigned to the water outlet side of the valve 15. It carries a corresponding pipe socket 32 as a valve outlet and accommodates a mechanism 33 for actuating the piston rod 25.
  • the intermediate plate 26 has a central bore 34 through which the piston rod 25 is guided.
  • further openings 35 are also provided which, like the central bore 34, serve for the passage of water from the chamber 27 assigned to the water inlet side into the chamber 28 assigned to the water outlet side. This passage is blocked in the closed position of the valve 15 by the valve cap 30 and the sealing plunger 31.
  • the valve cap 30 is a hollow cylinder with a bottom 36 drawn in on the underside and a fixed cover 37. In the plane of the bottom 36, an edge step 38 which is concentrically widened outward is formed on the valve cap 30. With this edge step 38, the valve cap 30 lies sealingly the intermediate plate 26. An elastomeric ring 39 embedded in the intermediate plate 26, which surrounds the openings 35 in the intermediate plate 26, serves to seal and guide the edge step 38. The valve cap 30 is held on this elastomeric ring 39 by the water pressure in the first chamber 27. The water pressure acts on the upper side 40 of the stage 38 and the cover 37, which closes the valve cap 30 at the top.
  • Bores 42 are provided in the side wall 41 of the valve cap 30 through which water can flow into the interior of the valve cap 30. The further path of the water is blocked by the sealing plunger 31.
  • the sealing plunger 31 is axially movably guided in the interior of the valve cap 30 and is supported by means of a compression spring 43 against the cover 37 of the valve cap 30.
  • the sealing plunger 31 sits sealingly on an O-ring 44, which in turn is supported against the bottom 36 of the valve cap 30.
  • the sealing plunger 31 is held in this sealing position at the same time by the force of the compression spring 43 and the water pressure acting in the interior of the valve cap 30 of the first chamber 27.
  • the piston rod 25 is firmly connected at one end 45 to the sealing plunger 31. It protrudes through a central opening 46 in the bottom 36 of the valve cap 30. The area around the piston rod 25 forms a passage channel for water which flows in through the bores 42 in the side wall 41 of the valve cap 30.
  • the piston rod 25 is guided in the central bore 34 of the intermediate plate 26 and a disk 47, which is arranged in the second chamber 28.
  • Disc 47 has a central bore 48 in which a pin 49, which is coaxially formed on the piston rod 25, runs.
  • the mechanism 33 is used to move the piston rod 25 in the axial direction. It essentially consists of a lever 16, the lever arm 50 of which is articulated to the piston rod 25 at an approximately right angle.
  • the other lever arm 51 is led out of the housing 24 in a sealing manner via a lateral connection piece 52.
  • a pivot 53 is provided in the socket 52, around which the lever 16 is pivoted by pressing a button 17. This pivoting movement is converted into an axial upward movement of the piston rod 25, which initiates the flushing process.
  • the axial movement of the piston rod 25 takes place against the force of a return spring 54.
  • the return spring 54 wraps around the piston rod 25 and is arranged in the lower chamber 28. It is supported on the one hand against the intermediate plate 26 and on the other hand against a collar 55 which is integrally formed on the piston rod 25.
  • a sleeve 56 serves as a stop, which is molded onto the cover 37 of the valve cap 30 and projects into the interior of the valve cap 30.
  • the outlet valve 15 described allows the amount of rinsing water to be metered in two stages.
  • a partial flush is triggered by gently depressing the lever 16.
  • the A correspondingly short axial deflection movement of the piston rod 25 leads to a lifting of the sealing plunger 31 from the 0-ring 44 without the sealing plunger 31 reaching the stop position on the sleeve 56.
  • the water flow through the bores 42 in the side wall 41 of the valve cap 30, the opening 46 and the opening 35 of the intermediate plate 26 is released.
  • the forces of the compressed springs 43 and 54, the pressure prevailing in the upper chamber 27 and a flow pressure act on the sealing plunger 31.
  • a full flush can be triggered either promptly or with a delay with this outlet valve 15.
  • the lever 16 is pressed down deeply for the full flush.
  • the compression spring 43 is strongly compressed by the corresponding axial movement of the piston rod 25 and the sealing plunger 31.
  • the sealing plunger 31 hits the sleeve 56 and moves beyond this stop position. This movement lifts the valve cap 30 from its sealing seat on the ring 39. This opens a wide annular gap between the valve cap 30 and the intermediate plate 26, through which an additional, strong water flow passes.
  • the resulting flow pressure holds the valve cap 30 in the raised position until the pressure vessel 2 is almost completely empty. Thereafter, the valve cap 30 is returned to the sealing position by the force of the return spring 54 and the sealing plunger 31 by the combined action of the compression spring 43 and the return spring 54.
  • a partial flush is first triggered by gently depressing the lever 16 and the lever 16 is then held in place. Initially, only the sealing plunger 31 is raised into an open position for the partial flushing. During the partial rinse, water flows out of the pressure vessel 2 and the pressure in the first chamber 27 assigned to the water inlet side drops. The closing of the sealing plunger 31 which is usually triggered thereby is prevented by holding the lever 16 in the depressed position. With this holding the compression spring 43 is manually held under tension. As the pressure in the first chamber 27 drops, the force exerted on the valve cap 30 by this pressure gradually decreases until it finally becomes less than the force of the compression spring 43. The valve cap 30 is then lifted out of its sealing seat by the compression spring 43, and the full flush starts.
  • the pressure vessel 2 can take various forms and be installed at different positions because its operation is independent of the force of gravity.
  • the pressure vessel 2 is spherical and is arranged somewhat above the water closet 1, as is shown in simplified form in FIG. 3.
  • the pressure vessel 2 located above the water closet 1 according to FIG. 3 can, however, also be cylindrical, wherein the cylinder center axis according to FIG. 3 can be horizontal.

  • 5 shows an embodiment in which the entire pressure vessel 2 is installed in the ceramic part of the water closet 1, that is to say it is not visible from the outside.
  • the pressure vessel 2 can be spherical or cylindrical.
  • the flushing device can provide an excellent flushing effect with minimal water consumption. This is first achieved by flushing the water at the full pressure of the water supply network. As with the flush valve, you get by with very small amounts of water.
  • the outlet valve described also allows this amount of water to be metered in partial rinses, prompt or delayed full rinses, so that the average water requirement drops further.
  • the content of the pressure container is approx. 5 l.
  • the delivery rate of the injector at 4.5 bar line pressure and fully open outlet valve is 15 1 air / min. and 11.5 1 water / min.
