Definitions

  • the invention relates to a flushing device for flushing a toilet bowl according to the preamble of claim 1.
  • 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.
  • a toilet bowl is to be created, which can be cleaned very thoroughly and with as little water.
  • a further subset of the flushing water is generated for the purpose of cleaning the flush bowl in order to form a flushing vortex.
  • the cleaning of the toilet bowl can thus be carried out with two subsets, with a subset of the Spülwirbel and with the other subset of a conventional purge flow can be generated by means of a flushing channel.
  • these two subsets of the rinsing water an upper area of the bowl inside is cleaned.
  • the cleaning of this area is thus carried out with two different types of spray, one of which is the Spülwirbel. This allows the area to be thoroughly cleaned with even less water.
  • Said further subset is according to a development of the invention, a fourth subset of the rinse water.
  • a first subset and the fourth subset an upper region of the inside, with a second subset a middle region of the inside of the toilet bowl and a fourth subset of the siphon is rinsed and cleaned. This can be achieved with relatively less rinse water flushing, which usually does not require a post-cleaning.
  • the rinsing vortex can be generated below an upper rinsing ring of the toilet bowl. Furthermore, it is preferably provided that the further subset can be dispensed into the toilet bowl at an outlet which is located below the upper flushing ring.
  • each valve and a controller are provided according to a development. The subsets can then be submitted in time according to the control in the appropriate period. The first and the fourth subset can be dispensed with each other, successively or overlapping in time to the toilet bowl. This allows further control of the necessary flushing water and in particular an adaptation to different Klosettschdorfln.
  • 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 device according to the invention thus makes it possible to clean or rinse three different areas with different partial quantities and different water pressures for cleaning and rinsing a toilet bowl.
  • the four 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 invention also relates to a water closet with such a flushing device and a particularly suitable 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 rinsing device 2 has a rinsing container 28 for storing rinsing water 43.
  • the rinsing container 28 may be provided in a conventional manner with an actuating device, not shown here, for triggering a rinsing and an outlet valve.
  • the water is delivered to a distribution device 30, which delivers the rinse water to a first valve 31, a second valve 32, a third valve 33 and to a fourth valve 80.
  • These valves 31 to 33 and 80 are preferably adjustable independently of each other, so that finally four different subsets of the rinsing water can be delivered to the toilet bowl 6.
  • the valves 31 to 33 and 80 are manually adjustable valves or solenoid valves which are connected to a control device not shown here.
  • the pump 29 may be arranged outside or inside the washing container 28.
  • a cistern which is a pressure cistern or in which a device is arranged, in which a portion of the rinse water 43 is pressurized, as shown in the US-B-7,096,517 disclosed by the applicant.
  • the dispensed in the case of flushing via the valve 31 subset of the flushing water passes through a first line 34 to a connecting piece 65 of a terminal 25 of the toilet bowl 6.
  • This connection piece 65 is suitable for example for a plug connection with the first line 34.
  • the aforementioned first Subset in a flushing ring 18 which is formed on an inner side 10 of the toilet bowl 6 corresponding to the cross section in this area of the toilet bowl 6 circumferentially.
  • the flushing ring 18 is according to Fig. 1 provided in a lower portion with an outlet 64, which may be formed by a gap or through a plurality of nozzle-shaped openings. The water flowing down through the outlet 64 runs down along the inner side 10 and finally enters a siphon 12.
  • the inner side 10 is thereby wetted and cleaned in an upper area A and in a middle area B.
  • the upper area A is an area of the inner side 10, which is usually relatively little polluted.
  • the middle region B is a region of the inner side 10, which as a rule becomes more heavily polluted than the upper region A.
  • the line 67 is in FIG Fig. 1 indicated where, for example, the area A in the area B passes.
  • the region B merges approximately at the level of the dotted line 68 into a lowermost, generally heavily soiled, region C.
  • Line 68 is at about the level of the siphon water level.
  • Fig. 2a In the Fig. 2a is the purge flow, which is discharged through the purge ring 18 indicated by arrows 37. Also indicated is the siphon water 69 and, with a dash, the level 69a of the siphon water.
  • 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.
  • several 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 water jets leaving the nozzle openings 20 are preferably directed against a point 70 on an inner side 71 of the siphon 2 ,
  • the point 70 is located slightly in front of the deepest point 72 of the siphon 12.
  • the impinging water is reflected and accelerates the water in the siphon 12 to an outlet opening 14 of a Siphonstutzens 13 out.
  • 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 water flowing into the toilet bowl 6 when the fourth valve 80 is open forms a fourth subset.
  • the water of this subset flows in the toilet bowl 6 from an inlet 81 to an outlet 82.
  • the water passes on the inside 10 substantially horizontally in the toilet bowl 6 and flows as Spülwirbel along the inside 10 down.
  • this rinsing vortex is indicated by an arrow 83.
  • the rinsing vortex flows down the inner side 10 in the manner of a spiral, thereby cleaning the inner side 10 below the nozzle openings 17.
  • the diameter of the rinsing vortex becomes smaller in accordance with the funnel-shaped formation of the inner side 10 and causes additional cleaning of the areas A and B.
  • the amount of water in the annular channel 16 can thereby be substantially reduced, without the entire cleaning effect would be reduced.
  • the total amount of rinse water available for rinsing is thus preferably divided into four subsets, which are adapted in terms of volume and pressure to the areas A, B and C.
  • the valves 31, 32, 33 and 80 allow suitable timing of these subsets.
  • the volumes of these subsets can be optimally controlled.
