Definitions

  • the invention relates to a cistern for flushing a toilet with a connection to a toilet bowl and controlled by a flush valve water drain, in which the flush valve protrudes with an extension through a flush water supply above the flush valve and exhaust air is sucked out of the toilet bowl by a vacuum generator.
  • the object of the present invention is therefore to improve the cistern of the type mentioned in the introduction in such a way that it allows an optimal combination of flushing functions on the one hand and suction functions on the other hand with simple installation and comparatively small dimensions.
  • a suction pipe connected to the vacuum generator extends through the flushing water, which is connected on the one hand to an upper end of the extension designed as a pipe facing away from the flushing valve, and on the other hand to at least one ventilator which receives the exhaust air extracted from the toilet bowl leads and that the flushing valve with the extension and the suction pipe form a drain fitting which extends through a housing receiving the flushing water supply and is fastened in an opening leading out of the housing.
  • this ventilator can be designed either as a filter that absorbs the exhaust air or as an exhaust air system into which the extracted exhaust air is discharged.
  • this exhaust air system for example, several toilet bowls can be connected, the exhaust air of which is disposed of by the exhaust air system.
  • a sewage system as the exhaust air system, through which a general sewage disposal is carried out.
  • an odor trap is also provided in the cistern, with the help of which the prevailing in the sewage system is prevented odor-laden atmosphere can penetrate into the toilet bowl.
  • the particular advantage is that the drain assembly can be easily installed in the cistern housing and aligned in a desired position.
  • This waste set only requires a sealing point within the cistern, which can be produced relatively easily and cheaply.
  • the cistern remains clear even for the layperson and can therefore be installed and removed, if necessary, and then reassembled without much effort. Subsequent corrections in the position of a drain socket protruding from the cistern with respect to the cistern on the one hand and a connection to a sewage system on the other hand are easily possible by twisting the drain fitting within the opening.
  • the suction pipe is guided within the extension.
  • the suction pipe guided inside the extension only requires an appropriately dimensioned extension in order to have enough space to accommodate the exhaust to create suction pipe.
  • the size difference between the extension on the one hand and the suction pipe on the other hand can be kept relatively small because the annular space created by the size difference is sufficient for the extraction of the exhaust air.
  • the flushing water only comes out of the cistern in the area of the flush valve.
  • the extension at its lower end facing the flushing valve is designed as a valve part cooperating with a valve seat, between which and the valve seat the flushing water runs in the direction of the toilet bowl when the flushing valve is open. Since the flushing water does not pass through the extension when flushing the toilet, the dimensioning of its cross section is not predetermined by the amount of flushing water that runs off.
  • this extension can be brought about with the help of a bell, which surrounds both the extension and the suction pipe guided in it. This bell dips with its outer edge into a quantity of water, so that exhaust air introduced through the extension can be sucked into the suction pipe without exhaust air being able to escape from the bell.
  • a preferred embodiment of the invention is that the suction pipe is led out of the water drain outside the housing. In this way, an easy installation of the unit is possible. There is only one sealing point in the bottom of the housing, which can be correspondingly easily sealed against the opening extending through the bottom.
  • the odor trap necessary for connection to the sewage system is formed by a sealing water tank, which can be filled with part of the flushing water supply.
  • a quantity of sealing water in the sealing water container can be used for rinsing purposes.
  • the sealing water tank can be formed at the upper end of the extension. This construction of the sealing water tank has the great advantage that it is made small on the one hand and is structurally easily held in the cistern can be. It takes up little space within the housing and easily prevents the exhaust air atmosphere in the sewage system from entering the toilet bowl. It can be emptied quickly if a connection has to be made between the sewage system and the suction pipe for the purpose of extracting air.
  • the flushing valve has opening times of different lengths, depending on a desired amount of flushing water. In this way it is possible to preselect the amount of flushing water required for the respective flushing purpose with the aid of the flushing valve. In many cases, a much smaller amount of flushing water will suffice for flushing than corresponds to the entire contents of the cistern. In these cases, a relatively short opening time of the flushing valve can be sufficient, so that only relatively little flushing water runs out of the cistern towards the toilet bowl during this short opening time.
  • This control of the flush valve expediently has a float control which is dependent on the desired flush water quantity.
  • the opened flush valve is kept open longer or shorter, depending on the choice made.
  • the float is designed as a buoyancy body acting on the valve part via an extension guiding the float.
  • the specific weight of the float is such that it has sufficient buoyancy to be able to close the flush valve again at the desired speed.
  • the float can be assigned a float housing which, like the float, surrounds the drain set in a ring. A remainder of the flushing water collects in this float housing and drains out of the housing via the flush valve. In this residual water, the float sinks in the desired manner, so that the control of the closing speed of the flushing valve is ensured even when the largest amount of flushing water has escaped from the flushing valve.
  • a cistern essentially consists of a housing (1) and a drain fitting (3) extending through its interior (2). This is guided with its lower part (5) facing a toilet bowl (4) in a bottom (7) closing the housing (1) on its underside (6) facing the toilet bowl (4).

  • the drain fitting (3) extends through the floor (7) with a drain connector (13). It is sealed with the aid of a sealing system (14) against an opening (15) provided in the base (7).
  • This sealing system (14) is designed as an O-ring (16) which extends through a receptacle (17) which is fastened on an outer surface (18) of the drain socket (13) protruding from the housing (1).
  • This O-ring (16) bears firmly against an outer surface (19) of the base (7) facing it when the outlet connection (13) projects through the opening (15) into the interior (2) of the housing (1).

  • the connecting piece (31) can have a wall (32) which, in the area of its closest approach to the connecting piece (31), is identical to an inner wall (33) of the drain connector (13) facing the connecting piece (31).

  • This exhaust air enters through the extension (30) into the interior (64) of the bell (63) and is sucked into the suction pipe (29) through the sealing water tank (82) emptied from the sealing water. From there, the exhaust air reaches the ring (200) through the connecting line (199) and enters the ring space (312) through the access opening (202).

  • the float (313) is coupled to the extension (30) via a clamping ring (317). This clamping ring (317) adheres to the outer surface (315) so that it is in relation to the control expected from the float (313) the extension (30) can be adjusted higher or lower on the outer surface (315).
  • the float (313) floating in the rinsing water acts on the clamping ring (317) on its lower edge (319) facing the rinsing valve (49) with its upper edge (318) facing the rinsing button (62). In this way it is achieved that during the flushing, the float (313) floating in the flushing water lifts the extension (30) via the clamping ring (317) and the flushing valve (49) is opened in this way.
  • the clamping ring (317) is fastened in an upper position on the outer surface (315) of the extension (30). In this upper position, the float (313) controls a comparatively short opening time of the flushing valve (49) compared to a lower position of the clamping ring (317) facing the flushing valve (49).
  • the float (313) has a buoyancy which is less than the movable part of the drain fitting (3) connected to the extension (30). In this way it is achieved that the opened flush valve (49) is closed again due to the weight of the movable part.
  • the opening of the flushing valve (49) depends on the buoyancy of the float (313) and the point at which the clamping ring (317) is attached to the extension (30).
  • the buoyancy of the float (313) can be dimensioned such that the amount of flushing water emerging from the flushing valve (49) is, for example, either 6 liters or 9 liters.

Since this float housing (320) with an inner wall (321) and an outer wall (322) opposite the interior (2) of the housing (1) is separated, the flushing water remains in the float housing (320) even if the flushing water level in the remaining interior (2) has already fallen below an upper edge of the float housing (320) facing the flushing button (62) is. In this way it is achieved that the float (313) develops a constant buoyancy force regardless of the level of the rinsing water within the interior (2).
  • the float housing (320) surrounds the drain fitting (3) in a ring.
  • a gap (324) is provided between the inner wall (321) and the outer surface (315) of the extension, which is large enough so that the extension (30) can move in the longitudinal direction unaffected by the float housing (320).

  • This coil spring (327) also has a slight pretension in its tensioned state when the float (313) is inserted into the float housing (320).
  • This buoyancy force of the float (313) is sufficient to be able to open the flushing valve (49) even with an opening force that is slightly applied to the flushing button (62).
  • the weight of the movable part of the drain fitting (3) is sufficient to be able to close the flushing valve (49) against the tension of the spiral spring (327), the closing speed taking into account the tension from the float (313 ) is controlled.
  • the housing base (330) has a height in relation to the base (7) of the housing (1) which is dimensioned at least so that the flush valve (49) is closed properly. For this purpose, a safety distance must be provided between a lower edge (331) of the float (313) projecting into the interior (325) and the housing base (330) when the flush valve (49) is securely closed.
  • the float housing (320) is emptied via drain holes (370) which are arranged in the housing base (330) or in its immediate vicinity. About the size of this Ab holes (370), the outflow speed and thus the closing speed of the purge valve (49) is controlled.
  • the float housing (320) is supported in relation to the bottom (7) of the housing (1).
  • at least three legs (332, 333) distributed approximately uniformly over the circumference of the float housing (320) are provided. These legs (332, 333) are elastically attached to the float (3) on the float housing (320), so that they are able to perform movements in the direction of the drain (3) or in the opposite direction with a correspondingly applied force.
  • legs (332, 333) are supported at their ends (334) facing away from the float housing (320) on the bottom (7) of the housing (1).

  • the legs (332, 333) are elastically bent in the direction of the drain fitting (3), so that the end (336) is released from the hook-shaped roof part (337). Now the entire float housing, the interior (2) of the housing (1) can be removed.
  • the pocket (334) can be designed as a collar (338) concentrically surrounding the flushing valve (49), the hook-shaped dack part of which is acted upon by a plurality of legs (333, 332).

  • This rotating ring has an asymmetrical outer boundary (346).
  • safety grilles (219) are provided at least below the drive (43) in the direction of the sewage system (28), which ensure that flammable gases are deflagrated and have the same function as the grille of a miner's lamp have.
  • Such safety grilles (219) are expediently also provided on both sides of the drive (43).
  • this waste set (3) is that it can also be used in a suction toilet (349) without great difficulty.
  • This amount of residual water has an upper water level (351), the height of which is predetermined by a deflection edge (352), via which an in when flushing the toilet bowl (4) the amount of water (353) entering the toilet bowl (4) has to increase so that it reaches a suction nozzle (354) which immediately adjoins the deflecting edge (352).
  • This deflection nozzle (354) is delimited in the direction of the water flowing into the sewage pipe (27) by a narrow point (355), behind which an outflow space (356) increases in the direction of the sewage pipe (27). Because of this constriction (355), the water running out of the toilet bowl (4) is stowed so that an upper chamber (357) is completely filled by the amount of water (353) entering, in which the amount of water (353) entering above the deflection edge ( 352) is deflected in the direction of the suction supports (354). Due to the increase in volume behind the constriction (355), the water is sucked out of the toilet bowl (4).
  • this upper chamber (357) opens the connecting piece (31) which extends eccentrically through the drain port (13).
  • the connecting piece (31) is straight and emerges from the lower end (25) of the drain connector (13).
  • the connecting piece (31) runs essentially parallel to a center line extending through the drain fitting (3). It extends through a distribution space (358) into which the flushing liquid enters through the outlet connection (13) and from which it is distributed uniformly over the entire toilet bowl (4) along its edge (359).
  • connection piece (31) opens with its connection end (35) into a suction opening (361) which is provided in a wall (362) through which the distributor space (358) is separated from the upper chamber (357).
  • the connection sleeve (360) concentrically surrounds the suction opening (361). This suction opening (361) lies in a straight line below the connector (31).
  • the connecting sleeve (360) carries an elastic connecting piece (363).
  • This connecting piece (363) can be designed as a double sleeve, which engages with the lower end facing the connecting sleeve (360) and receives the connecting end (35) of the connecting piece (31) with its opposite upper end.
  • This arrangement of the suction opening (361) has a significant advantage, which is that the drain fitting (3) can be installed very easily on a suction toilet (349).
  • the connector (31) is first pushed with its connector end (35) into the elastic sleeve (360) which is placed on the suction opening (361).
  • the housing (1) is then slipped with its opening (15) over the suction pipe (29), which is connected to the connector (31).
  • the housing (1) is then fastened to the toilet bowl (4) in the usual way with screws and nuts (not shown).
  • the drain connector (13) can be attached to the housing base (7) with the connector (31) extending through it.
  • the position of the valve seat (52) formed on the nut (20) is thus fixed.
  • the valve part (53) attached to the extension (30) is turned off directed by pushing the extension (30) over the suction pipe (29).
  • the water level in the sealing water tank (82) is raised by a height (369) which corresponds to the water level in the toilet bowl (4) when the water from the upper chamber (357) runs through the constriction (355) in the direction of the sewage pipe (27). For this reason, it must be ensured that the sealing water does not run through the suction pipe (29) in the direction of the vacuum generator (42) and its drive (43). For this purpose, the suction pipe (29) is pulled up beyond the sealing water tank (82) towards the cover (9) of the housing (1) with its upper edge (364) so far that a water column (due to the negative pressure) 365) ends with its upper end (366) below the upper edge (364).
  • the sealing water tank (82) is arranged in an area within the housing (1) which is approximately halfway up the interior (2) enclosed by the housing (1). Due to this arrangement of the sealing water tank (82), the taper (67) can be made very long up to the lid (9), so that the upper end (366) of the water column (365) is in any case below the upper edge (364). In addition, a compensation space (367) can be provided below the bell (63) and above a level (97) of the sealing water (96) in the sealing water tank (82), which can hold a substantial part of the sealing water sucked out of the sealing water container (82) .
  • This compensation space (367) is provided in the direction of the cover (9) above the edging (77) between the taper (67) and the casing part (65). This prevents the sealing water (96) from entering the suction pipe (29) when the suction toilet (349) is being rinsed.
  • the housing (1) can easily be attached to the toilet bowl (4) of a suction toilet (349). Both the attachment of the flush valve and the arrangement of the extension (30) can be carried out if the housing (1) is already attached to the toilet bowl (4).
  • the rinsing valve (49) In order to prevent rinsing water inlet (115) from leaking out of the interior (2) of the housing, for example under its cover (9), even if there is a leak, the rinsing valve (49) must be opened is when an upper level of the flushing water (48) in the interior (2) is exceeded due to an uncontrolled inflow of flushing water (48).
  • an emergency float (368) is installed at this uppermost level of the flushing water (48), which must never be exceeded, which opens the flushing valve (49) so that flushing water that continues to flow into the interior (2) ( 48) through the flushing valve (49) into the toilet bowl (4) if the amount of incoming flushing water (48) is not sufficiently drained through the annular space (94) into the gap (50) between the extension (30) and the suction pipe (29) can be.
  • This emergency float (368) is expediently connected to the extension (30). Fastening the emergency float (368) on the annular outer wall (88) of the sealing water tank (82) has proven to be expedient.
  • This emergency float (368) is equipped with such a high buoyancy that it is able to open the entire movable part of the drain fitting (3) against the closing forces on the flushing valve (49).
