Definitions

  • the invention relates to a concealed cistern for a toilet or urinal basin, with a box body for storing flushing water, a float arranged within the box body and a filling valve controlled by means of the float.
  • Cisterns for toilets or urinals are known in various designs.
  • the actuating plates of concealed cisterns are usually made relatively small.
  • the dimensions of the inspection openings are accordingly limited.
  • the installation of the functional parts to be arranged in the box body is fundamentally difficult because of the small inspection opening.
  • a concealed cistern for a toilet or urinal basin with a filling valve, a drain valve, a flush pipe and an electrical actuating device for triggering a flush is proposed, in the case of the box body receiving the flushing water a connection space or housing for receiving an electrical control and a lockable water connection is arranged, wherein the connection space or the housing has an inspection opening on its front side, which is dimensioned and arranged so that it is covered by the latter after the assembly of the toilet or urinal bowl.
  • a purely mechanical actuation device for triggering a flush is in the DE 20 2007 017 789 U1 known concealed cistern not provided. Rather, an electrical actuating device and an electrical control are provided, by means of which an electrical actuator is actuated, which opens and closes the drain valve.
  • the drain valve has a ball or a rotatable flap as the valve body.
  • the filling valve is electrically controllable Filling valve executed, which are assigned at least two water level sensors arranged in the box body or in its wall, which are vertically spaced from one another.
  • the upper water level sensor can be used to define a desired fill level, while the lower water level sensor can be used to define the amount of water with regard to the so-called two-volume flushing technology, after which the drain valve is closed.
  • the US 2009/0277513 A1 Figure 11 shows a shut-off valve assembly for use with a toilet tank comprising a float located within the toilet tank and a water-retaining guide which allows the float to move vertically, the guide having drainage holes below the lowest vertical position of the float through which the retained water is slowly released when the water in the tank sinks below the drainage holes.
  • a magnet attached to the bottom of the float then activates a magnetic shut-off valve, which is designed to shut off the flow of water to the toilet tank and is arranged below the toilet tank.
  • US 6109294 A is another structure with a cistern and a valve / float arrangement located therein, which has a magnetic coupling.
  • the present invention is based on the object of creating a concealed cistern of the type mentioned, the float-controlled filling valve of which is arranged outside the cistern body in order to enable a maintenance-free cistern, the filling valve being controllable leak-free.
  • the filling valve of the concealed cistern according to the invention is arranged outside of the box body, the filling valve and a control element connected to the float being provided with a magnet system which has at least one magnet and a magnetic or magnetizable counterpart interacting with the magnet, the magnet and the counterpart being arranged on opposite sides of a liquid-tight wall of the filling valve and / or the box body, the filling valve having a valve body as the main valve body and a control valve body, wherein the control valve body is provided with the magnet or the magnetic or magnetizable counterpart, and wherein the control valve body is designed as a control piston.
  • the filling valve arranged outside the box body can in principle be actuated leak-free by means of the float or the control element connected to the float without an associated opening in the housing wall of the box body.
  • the filling valve can thus be arranged outside the box body without the risk of water damage.
  • the magnet system of the cistern according to the invention can also be referred to as a level-dependent magnetic coupling.
  • the filling valve is preferably arranged below the box body and is accessible for maintenance purposes via an inspection opening that can be completely covered by the toilet or urinal bowl.
  • Such an inspection opening arranged behind the toilet or urinal bowl can be realized with dimensions that are larger than the dimensions of a conventional inspection opening of a concealed cistern which is arranged in the front wall above the toilet or urinal bowl.
  • the counterpart which interacts with the magnet is preferably designed as a permanent magnet.
  • the cistern according to the invention is characterized by good reproduction behavior with regard to the filling process.
  • the repeatability of the filling quantity is characterized by a very small deviation.
  • the magnet system provides a natural hysteresis.
  • the filling function responds shortly after the flush has been triggered.
  • control element connected to the float is rod-shaped.
  • the control element therefore requires little space in the cistern body of the cistern, can be guided relatively easily and thus ensures reliable control of the filling valve.
  • the control element connected to the float can also be referred to as a control rod.
  • the float is guided easily through the control rod and is, for example, essentially cuboid.
  • the float preferably has a through-opening, for example in the form of a bore, through which the upper end of the control element is inserted.
  • the control element is provided with a stop which is assigned to the underside of the float.
  • the end of the rod-shaped control element protruding from the top of the float is provided with an upper stop for the float.
  • the end of the rod-shaped control element protruding from the top side of the float is preferably provided with an external thread onto which a nut and preferably a lock nut are screwed.
  • the nut forms the upper stop.
  • the distance between the lower and the upper stop of the control element is preferably greater than the length of the through opening or bore, so that the float strikes the upper stop when it floats up while the cistern is being filled. This improves the release of the magnetic coupling.
  • the magnet or the magnetic or magnetizable counterpart of the magnet system is attached to the lower end of the control element.
  • This configuration is advantageous for the reliable functioning of the level-dependent control of the filling valve.
  • this configuration simplifies the structural implementation of a space-saving guidance of the control element, which is preferably designed in the form of a rod.
  • the control element connected to the float is preferably guided in a guide arranged in the box body and / or on the underside of the box body.
  • a guide which for example has an essentially vertically extending channel or pipe section or consists of such a channel or pipe section, can be implemented cost-effectively.
  • the filling valve is preferably arranged below the guide. This arrangement is favorable for the assembly of the filling valve and for any dismantling of the filling valve that may be required.
  • Another advantageous embodiment of the invention is characterized in that the box body is provided with a drain pipe socket to which a drain valve is connected. If, according to this embodiment, the drain valve is also arranged outside of the box body, this enables a largely maintenance-free concealed cistern.
  • the valve housing of the drain valve defines, for example, a housing chamber for receiving water, in which a valve body is arranged.
  • the housing chamber can also be referred to as the main chamber.
  • the valve body of the drain valve is provided with a secondary chamber for receiving water, the volume of which for water is smaller when the drain valve is open than when the drain valve is closed.
  • the secondary chamber is delimited by a flexible and / or movable wall section, which is preferably designed in the form of a bellows.
  • a secondary drain valve is assigned to the secondary chamber, which in a first position allows water to flow into the secondary chamber and in a second position allows water to flow out of the secondary chamber.
  • the drain valve has the advantage over conventional cistern drain valves that the forces required to actuate the secondary drain valve and thus the forces required to actuate the drain valve are relatively small.
  • the secondary drain valve is moved into the second position, in which the drainage of water from the secondary chamber is enabled. At the same time, a further inflow of water into the secondary chamber is prevented at least to the extent that the water volume flow flowing out of the secondary chamber is greater than the water volume flow flowing into the secondary chamber. This reduces the water pressure in the secondary chamber compared to the water pressure in the main chamber, with the result that the valve body is moved away from the valve seat and the flexible and / or movable wall section of the secondary chamber is compressed or pushed into one another.
  • the drain valve preferably has a valve body actuated by means of a magnetic coupling, the magnetic coupling having at least one magnet and a magnetic or magnetizable counterpart interacting with the magnet, the magnet and the counterpart being arranged on opposite sides of a liquid-tight wall of the drain valve.
  • This valve body actuated by means of a magnetic coupling is particularly preferably the valve body of the auxiliary drain valve.
  • the box body is provided with an overflow line, the lower end of which is connected to a connection piece assigned to the drain valve, which opens below the valve body.
  • control valve body of the filling valve is designed as a control piston. This is advantageous with regard to the magnetic coupling with the preferably rod-shaped control element of the float and the required switching movements of the control valve body and the control element connected to the float.
  • control piston in the filling valve is preferably guided axially in alignment with the control element connected to the float.
  • the filling valve of the concealed cistern preferably has a water inlet connection and a water outlet connection, the water outlet connection serving to connect a line for filling the box body.
  • This configuration is favorable in terms of manufacturing technology and in terms of pre-assembly of the concealed cistern.
  • the concealed cistern 3 shown is intended for combination with a toilet or urinal basin (not shown).
  • the concealed cistern 3 is essentially maintenance-free and therefore, in contrast to a conventional concealed cistern, does not have an inspection opening via which a drain valve and a filling valve can be mounted or dismantled inside the cistern.
  • the filling valve 6 and the drain valve 7 are arranged outside of the box body 3.1 of the cistern 3.
  • the box body 3.1 is composed of an upper container part 3.11 and a container base 3.12 connected to it in a liquid-tight manner.
  • the container base 3.12 has a circumferential nozzle or collar 3.13 into which a lower, nozzle-shaped end 3.14 of the upper container part 3.11 is inserted in a liquid-tight manner using an annular seal.
  • the container base 3.12 is provided with laterally protruding fastening elements 3.5, which have essentially horizontally extending connecting legs with through holes (fastening holes) 3.6.
  • the upper container part 3.11 is provided with laterally protruding fastening elements 3.7 which have essentially vertically extending connecting webs with through holes (fastening holes) 3.8.
  • the box body 3.1 is provided with a drain pipe socket 3.2 to which the drain valve 7 is connected.
  • the drain pipe stub 3.2 is preferably materially connected to the container base 3.12 or is integrally formed thereon. Alternatively, the drainage pipe stub 3.2 can also be screwed to the box body 3.1 or the container base 3.12 in a liquid-tight manner using an annular seal.
  • the valve housing of the drain valve 7 defines a chamber (main chamber) 7.1 in which a valve body is arranged.
  • the valve body is provided with a secondary chamber 7.2, the water absorption volume of which is smaller when the drain valve 7 is open than when the drain valve 7 is closed.
  • the secondary chamber 7.2 is delimited by a flexible wall section, which is designed, for example, in the form of a bellows 7.6.
  • the secondary chamber 7.2 is assigned a secondary drain valve 7.5 which, in a first position, allows water to flow from the cistern 3 into the secondary chamber 7.2 and, in a second position, allows water to flow out of the secondary chamber 7.2.
  • the inflow of water from the box body 3.1 into the secondary chamber 7.2 takes place via an inflow line 7.3 arranged parallel to the outlet pipe socket 3.2.
  • the secondary drain valve 7.5 is moved into the second position, in which an outflow of water from the secondary chamber 7.2 is enabled. At the same time, a further inflow of water into the secondary chamber 7.2 is prevented. This reduces the water pressure in the secondary chamber 7.2 compared to the water pressure in the main chamber 7.1, with the effect that the valve body is removed from the valve seat and the bellows 7.6 of the secondary chamber 7.2 is compressed.
  • the box body 3.1 is provided with an overflow line 40, which is preferably arranged within the box body 3.1.
  • the overflow line 40 consists, for example, of a rigid, essentially vertical pipe, the inlet opening 40.1 of which is arranged in the upper region of the box body 3.1 at a distance from the upper wall of the box body 3.1.

  • the overflow line 40 is provided with an annular seal 50 in the area of the through opening 3.9.
  • the lower end of the overflow line 40 is connected to a connection piece 7.4 assigned to the drain valve 7, which opens into a flushing pipe 5 below the valve body of the drain valve 7.
  • the connection of the overflow line 40 to the connecting piece 7.4 can be realized, for example, using one or more pipe sections 40.3, in particular a pipe angle 40.2.
  • the filling valve 6 is float-controlled, the float 8 arranged in the box body 3.1 of the cistern 3 being connected to a preferably rod-shaped control element 8.1.
  • the rod-shaped control element 8.1 which can also be referred to as a control rod, is guided in a guide 3.3 arranged in the box body 3.1.
  • the filling valve 6 is arranged below the guide 3.3.
  • the guide 3.3 is preferably cohesively connected to the box body 3.1 or the container base 3.12 or is integrally formed thereon. Alternatively, the guide 3.3 can also be screwed liquid-tight to the box body 3.1 or the container base 3.12 using an annular seal.
  • the guide 3.3 can be viewed as part of the box body 3.1 or the container base 3.12.
  • the float 8 is, for example, essentially cuboid. To connect the float 8 to the control rod 8.1, the float 8 has a through opening 8.2 through which the upper end of the control rod 8.1 is inserted.
  • the control rod 8.1 is provided with a stop 8.11, which is assigned to the underside of the float 8.
  • the end of the control rod 8.1 protruding from the top of the float 8 is provided with an upper stop 8.12.
