Definitions

  • the invention relates to a rinsing device for rinsing a toilet bowl, with a rinsing container, from which the toilet bowl a Spüligange can be supplied, this rinse water is divided into a subset for cleaning an upper portion of the toilet bowl and another subset for moving water, in the Toilet bowl is present.
  • the invention also relates to a water closet with such a flushing device and a toilet bowl.
  • Flushing devices of this type have long been known. During a flushing process, the components present in the siphon are flushed into the disposal line, the inside of the toilet bowl is cleaned and finally the siphon is refilled with water. It has long been the goal of such flushing devices to perform the flushing and cleaning the toilet bowl as efficient as possible and with as little water.
  • the effectiveness of the rinsing process can be improved in a known manner in which a so-called jet nozzle is provided in the siphon. A portion of the rinse water is supplied under relatively high pressure of this jet nozzle. Another subset is fed to a flushing channel having a plurality of nozzles through which the flushing water is discharged for cleaning the inside of the toilet bowl.
  • a flushing device of the type mentioned is for example by the WO 2009/000881 known.
  • the water present in the washing container is fed to a pump, which supplies a part of the water to a flushing channel and another part of a jet nozzle arranged in a siphon.
  • the invention has for its object to provide a flushing device of the type mentioned, which allows an even more thorough cleaning and flushing the toilet bowl. This should be possible with a comparatively small amount of flushing water. Also, a toilet bowl is to be created, which can be cleaned very thoroughly and with as little water.
  • the object is achieved in that means are provided with which the flushing water is divided into at least three subsets.
  • By dividing the amount of flushing water in at least three subsets it is possible to purify the inside of the toilet bowl even more targeted in at least three different areas and initiate the flushing process.
  • the invention is based on the finding that the inside of a toilet bowl can generally be subdivided into three different soiled areas. An upper area is relatively little polluted and here it is sufficient to wet the inside of the toilet bowl. This can be done at comparatively low water pressure and comparatively low amount of flushing water. This area can be cleaned with a first subset of the rinse water.
  • the rinse tank can be a cistern with an inlet and an outlet valve, but there are also other rinsing conceivable here.
  • a second medium soiled area is located below the upper area. This area can be specifically cleaned with the second partial amount of water. Here, a higher water pressure and a higher amount of water is provided compared to the first subset.
  • a third area is inside the siphon. This area is usually the most polluted. It also contains the substances to be removed. The cleaning and the rinsing process can be carried out with the third subset.
  • the water pressure provided here is even higher than the water pressure of the second subset.
  • the volume of this third subset may be higher than the volumes of the other two subsets.
  • the inventive device thus allows for cleaning and rinsing a toilet bowl three different areas with different subsets and to clean or rinse different water pressures.
  • the three subsets can be optimally adapted to the functions to be fulfilled or to the different areas. This also applies to the respective time of triggering.
  • the second subset is discharged at a higher pressure than the first subset and the third subset at a higher pressure than the second subset.
  • the pressure of these subsets is then particularly suitably adaptable to the different functions.
  • the first subset is released due to the gravitational force. This subset is thus delivered without pressure build-up, for example by means of a pump.
  • a pump which serves to deliver at least a portion of the amount of flushing water under pressure to the toilet bowl.
  • substantially the entire amount of flushing water is stored under pressure prior to delivery.
  • the amount of water is then discharged, for example at a junction in three different lines.
  • a first, a second and a third valve are provided. These valves are then adjusted according to the intended pressures.
  • the valves can be controlled and adjustable via a control device. This makes it particularly easy to achieve an optimal distribution of the three subsets and also an optimal classification of the different pressures and volumes.
  • a pump is provided, which is operated with a turbine, by the water of a water pipe is driven.
  • the flushing device according to the invention can then be operated in a particularly energy-saving manner. Connections, such as electrical connections can be avoided.
  • a pressure accumulator for example one with a compression spring piston.
  • the pump or such a pressure spring piston can also be operated for example with a motor.
  • the first subset is delivered according to a development of the invention by means of a purge ring.
  • This flushing ring is located in an upper area of the toilet bowl.
  • This flushing ring according to one embodiment of the invention has a circumferential gap at which the rinse water is released under relatively high pressure for wetting the inside of the toilet bowl.
  • a flushing channel is provided, which is also arranged in an upper region of the toilet bowl.
  • This flushing channel is preferably provided with a plurality of nozzle openings, which are directed against said central area. According to a development of the invention, this flushing channel is arranged above the flushing ring.
  • the flushing ring and the flushing channel are each provided with a separate connection for receiving the corresponding subsets according to a development of the invention.
  • annular nozzle is preferably provided which is arranged in a lower region and preferably approximately at the level of the level of the siphon water.
  • This annular nozzle preferably has a plurality of nozzle openings or a circumferential gap through which the rinse water is discharged into the siphon at a comparatively high pressure. The flushing water discharged through the ring nozzle accelerates the water in the siphon and the components contained therein, and at the same time thoroughly cleans the inside of the siphon.
  • the refilling of the siphon with water is preferably carried out by means of the flushing ring and thus with water, which is discharged with comparatively low pressure in the toilet bowl.
  • water which is discharged with comparatively low pressure in the toilet bowl.
  • the invention also relates to a water closet with such a flushing device and a toilet bowl.
  • FIG. 1 shown water closet 1 has a flushing device 2, which is provided for rinsing and cleaning a toilet bowl 6.

  • the rinse water discharged during a rinse through the second valve 32 passes via a second line 35 to a connecting piece 66 of the connection 25.
  • the second subset of the rinse water enters a rinsing channel 16, which is arranged at an upper edge 8 of the toilet bowl 6 .
  • the flushing channel 16 is located above the flushing ring 18 and also preferably extends over the entire circumference of the edge 8.
  • the flushing channel 16 forms with the upper edge 8 an opening 7 of the toilet bowl 6.
  • In a lower region of the flushing channel 16 at a plurality of Nozzle openings 17 open, so that this second subset can be discharged through these nozzle openings 17 to the toilet bowl 6.
  • the nozzle openings 17 form a second outlet and are directed so that the outflowing water impinges on the inside 10 with comparatively high energy in the area B.
  • a plurality of jets are formed, which are directed specifically against the area B and clean this area B.
  • the volume of the second subset is preferably greater than the volume of the first subset and preferably also has a higher pressure. For cleaning the area B, it is thus preferable to use a higher pressure and a higher volume of the rinsing water.
  • the delivery of these two subsets can also be staggered over time. In particular, it is provided that the first subset is delivered before the second subset. However, it is also conceivable that both subsets are delivered substantially simultaneously and thus synchronously.
  • arrow 22 is in Fig. 1 indicated the direction in which the first subset flows into the purge ring 18.
  • the arrow 23 indicates the direction in which the second subset flows into the toilet bowl 6.
  • the arrows 21 indicate the direction of the water jets, with which the area B is cleaned.
  • the discharged from the third valve 33 water forms a third subset, which is discharged via a third line 36 to an annular nozzle 19.
  • This annular nozzle 19 is arranged on an outer side 9 of the toilet bowl 6 and is also formed circumferentially.
  • the annular nozzle 19 has a nozzle not shown here, on which the third line 36 is connected, for example pluggable with the annular nozzle 19.
  • Within the annular nozzle 19 extends a circumferential channel 19 a, which is connected to a plurality of nozzle openings 20.

  • the effluent from the nozzle orifices 20 water and the reflected water also clean the inside 71 of the siphon 12.
  • the third subset thus causes a purge and also a cleaning of the inside 71.
  • the third subset flows in the third line 36 with a pressure substantially is higher than the pressure of the second subset in the second line 35.
  • the volume of the third subset is greater than the volume of the second subset.

  • the Fig. 3 shows with a volume curve 41, the purge amount per unit time. This is essentially constant and amounts to, for example, one liter of water per second. The entire flushing process takes about four seconds. The total amount of flushing water is thus about four liters of water.
  • a pressure curve 42 shows the pressure curve during the flushing process. During the first second of the pressure is comparatively small, for example, less than 0.1 bar. The water flows in this first phase according to the Fig. 2a down through the openings 64 along the inside 10 and cleans the inside 10 in the areas A and B. In a second phase, the in Fig. 2b is shown, the area B is cleaned with increased pressure by the water flowing from the nozzle openings 17 water.
  • the pressure here is preferably greater than 0.2 and less than 0.4 bar and, for example, 0.3 bar. However, smaller or higher pressures are also conceivable here.

As already explained above, the corresponding water jets are focused on a location 70 on the inside 71 of the siphon 12. The water flowing into the siphon thus has a comparatively high energy and can thereby empty the siphon 12 and in particular thoroughly clean it by turbulences.

If the inlet valve 50 is opened, water flows through the line 48 into the washing container 28 and fills it up to a certain level. Through the water flowing through the turbine is driven. With the driven turbine 39 energy is generated, with which a spring 73 of an energy storage 52 is tensioned. With the tensioned spring 73, for example, the pump 53 can be driven or a piston not shown here can be loaded.

  • the energy storage 52 may be arranged according to this in the washing compartment 28. There are also two or three arranged in the washing compartment 28 energy storage possible.
  • the piston 54 moves downwards due to the tension of the spring 73 and pressurizes the water present in the interior space 75. This is thereby promoted via a check valve 59 to the two valves 32 and 33. Water passes through the valve 32 to the flushing channel 16 and via the valve 33, water passes to the ring nozzle 19. The water provided above the flushing ring 18 passes from the flushing tank 28 'directly via a line 56 to the valve 31. The energy of this water results from the Gravity due to the height difference between the washing container 28 'and the openings 64.
  • the corresponding comparatively small pressure is sufficient here, since, as mentioned, only the inner side 10 in the areas A and B should be wetted.
  • the pressure is also sufficient to refill the siphon 12.
  • the movement of the piston 54 may be performed by any suitable drive. Instead of a motor here is also a turbine 49 or other suitable drive conceivable. If the siphon 12 is refilled and the piston 54 in the raised position, the flushing device 4 is ready for another flush.
  • the Fig. 7 shows a flushing device 5, seen in the flow direction in front of the valves 32 and 33 each have a memory 60 and 61 and a check valve 62 and 63, respectively.
  • the reservoirs 60 and 61 are filled with water 76 and 77, respectively.
  • filling air 78 and 79 is stretched, which is located in the memory 60 and 61, respectively.
  • the two valves 32 and 33 are closed.
  • these valves 32 and 33 are opened, water is discharged through the opened valves 32 and 33 due to the strained air 78 and 79, respectively.
  • the discharged through the first valve 31 water is only funded by the pump 39.
  • the water discharged through the valve 31 could also pass directly from the washing container 28.
