Definitions

  • the present invention relates to a feeding and flushing assembly (hereinbelow also indicated simply as feeding/flushing assembly) of a flush tank according to the preamble of claim 1.
  • flush tanks for toilets and other sanitary appliances are normally provided with a flushing valve for discharging a predetermined amount of water from the tank, and a feeding device for refilling the tank with water from the water mains after each flush.
  • a feeding device for a flush tank has an inlet, which in use is connected to a water mains connection to bring water to the feeding device, an outlet through which the water is poured into the tank, and a feeding valve, operated by a float and arranged between the inlet and the outlet; the float is mechanically connected to the feeding valve for selectively opening/closing the feeding valve depending on the position of the float, i.e. the water level in the tank.
  • Some feeding devices are equipped with a delayed filling system, which allows the opening of the feeding valve to be delayed from the time when the water in the tank falls below the level at which the float is placed. This prevents the feeding device from starting to fill the tank when the flushing valve is still open, thus avoiding unnecessary water consumption.
  • the tank empties out due to a water leak or a malfunction of the flushing valve
  • the water level in the flush tank drops more or less rapidly depending on the extent of the leak; in any case, the point is reached where the water no longer supports the float of the feeding device, therefore the feeding valve opens; the water enters the tank, but as the tank continues to leak, water continues to be wasted.
  • patent application EP-A-2942441 describes a device for feeding a flush tank for sanitary appliances, which saves water thereby avoiding waste, not only by delaying the opening of the feeding valve in the normal operation of the flush tank, but also by preventing the opening of the feeding valve in case of water leaks of any type from the tank, for example, leaks through the flushing valve, leaks due to breakage of the tank, etc.
  • the feeding device in EP-A-2942441 closes the feeding valve and keeps it closed when leaks occur.
  • the feeding valve can still be operated on to allow the filling of the tank with water.
  • the float controlling the feeding valve could also get stuck for other reasons, thus preventing the opening of the feeding valve and hence the inflow of water into the tank.
  • flushing devices such as disclosed by EP2489794A1 or US5375268A .
  • flushing devices are provided with a cable-operated flushing valve, wherein a cable connects a lever, operated by the user, with a movable member of the flushing valve. But the cable is not connected to any part of a feeding device.
  • the present invention relates to a feeding and flushing assembly of a flush tank for sanitary appliances, as defined in the appended claim 1 and, in its additional features, in the dependent claims.
  • the feeding/flushing assembly of the invention allows, in case of need, the tank to be filled even when the feeding valve remains closed, i.e. when the float controlling the feeding valve remains in a position such as to keep the feeding valve closed, for example because of a jam or malfunction of the float or following a leakage of water from the tank.
  • the feeding/flushing assembly of the invention can integrate the features described in the aforementioned patent application EP-A-2942441 : in this way, the feeding/flushing assembly of the invention, besides allowing water saving both in the normal operation of the flush tank (by delaying the inflow of water into the flush tank after discharge), and in the case of water leaks of any kind from the tank (for example through the flushing valve or due to other causes), ensures the possibility of controlling the inflow of water into the tank even in case of leaks.
  • feeding/flushing assembly of the invention can also be applied in different configurations and not necessarily in the presence of the system described in EP-A-2942441 .
  • the numeral 1 in Figure 1 shows, as a whole, a feeding/flushing assembly of a flush tank (not shown) comprising a feeding device 2 and a flushing valve 3.
  • the feeding device 2 comprises a support body 4, which extends substantially along an axis A (which is, in use, substantially vertical) and is provided on the inside with a channel 5; a feeding valve 6, which is supported by the body 4 and arranged along the channel 5; and a main float 7 mechanically connected, for example by means of a linkage 8, to a shutter (not shown) of the feeding valve 6 and movable for selectively opening/closing the feeding valve 6.
  • the body 4 comprises an upper head 9 and a pipe 10, which extends from the head 9 downwards along the axis A and is provided with a guide parallel to the axis A on which the float 7 is slidably mounted so that the float 7 can slide along the axis A (or parallel to the axis A).
  • the channel 5 has an inlet 12, which can be connected to an external pipe of a water mains via a fitting, and a main outlet 13, which, in use, flows into the flush tank.
  • the movement of the float 7 along the axis A (or parallel to the axis A) actuates the shutter of the feeding valve 6 to selectively open/close the channel 5.
  • the float 7 is housed inside a cup-shaped container 16 open at the top, which extends along the axis A and is integrally fixed to the body 4 and in particular to the pipe 10.
  • the container 16 is provided with a bottom discharge hole 17, for example, formed in a bottom wall 18 of the container 16.
  • the feeding device 2 includes the features described in EP-A-2942441 to prevent the opening of the feeding valve 6 in case of leakage of water from the tank.
  • the container 16 comprises a main tank 19, in which the float 7 is housed, and a siphon system 20 connecting the tank 19 to the discharge hole 17.
  • the siphon system 20 (only schematically and partially shown in Figure 2 ) is equipped with an upper service hole 21 and a service valve 22 cooperating with the service hole 21 to selectively open/close the service hole 21; the service valve 22 is actuated by a service float 23 connected to the service valve 22 by a stem 24 inserted with radial clearance in the discharge hole 17.
  • the float 23 is located outside the container 16 and below the container 16, therefore at a lower level than that of the main float 7.
  • the feeding device 2 also comprises an additional tank 29, which is arranged below the head 9 of the body 4 and integrally fixed to the body 4 and receives water (when the feeding valve 6 is open) from the channel 5 through an auxiliary outlet formed in the body 4 downstream of the feeding valve 6.
  • the tank 29 is provided with a bottom outlet hole 30 and a discharge hole 31, which is positioned (along the axis A) at a higher level than that of the outlet hole 30.
  • the outlet hole 30 is associated with an auxiliary valve 32 cooperating with the outlet hole 30 to selectively open/close the outlet hole 30.
  • the auxiliary valve 32 is actuated by an auxiliary float 33 connected to the auxiliary valve 32 by a stem 34 and placed beyond the outlet hole 30 outside the tank 29 and outside the container 16, in particular under the container 16, i.e. at a level (along the axis A) lower than the float 7 and the float 23.
  • the discharge hole 31 is placed above the container 16 and axially aligned with the main tank 19, so that the water flowing out of the additional tank 29 through the discharge hole 31 falls into the container 16 and precisely into the tank 19, which is open at the top.
  • the flushing valve 3 substantially extends along an axis X (vertical in use and parallel to the axis A of the feeding device 2) and comprises a support structure 37, which can be fixed to a bottom wall of the tank (for example by means of a threaded sleeve 38) and is provided with a discharge hole 39 delimited by a sealing seat 40, and a valve body 41 slidably housed along the axis X in the support structure 37 and provided at the bottom with a shutter 42 cooperating with the sealing seat 40 to close the discharge hole 39; advantageously, the valve body 41 comprises a pipe 43 which also serves as an overflow pipe.
  • the valve body 41 is raised by an operating mechanism 44.
  • the operating mechanism 44 comprises a pivoting lever 45 hinged to the support structure 37 in a fulcrum 46, and a connecting rod 47 connecting the lever 45 to the valve body 41; the lever 45 cooperates with at least one slider 48 operated by a push-button 49 operable by a user.
  • the rod 47 and the slider 48 engage the lever 45 on opposite sides of the fulcrum 46.
  • the rod 47 is connected to a first end 51 of the lever 45, and the slider 48 acts on a second end 52 of the lever 45.
  • the slider 48 is supported by the support structure 37 and can slide with respect to the support structure 37 parallel to the axis X.
  • the slider 48 when operated by the user by means of the push-button 49, slides downwards parallel to the axis X, the slider 48 pushes the end 52 of the lever 45 downwards; the lever 45 rotates on the fulcrum 46, and the end 51 connected to the rod 47 rises, thereby also lifting the valve body 41.
  • the operating mechanism 44 may be of any other known type (also of the pneumatic, electro-mechanical, electronic type, etc.).
  • the operating mechanism 44 comprises a lever 45 or other equivalent element which, when the operating mechanism 44 is operated by the user, performs a translational movement with a prefixed stroke parallel to the axis X, in particular upwards.
  • the feeding device 2 comprises a control cable 54 and an unlocking float 55 acting on the cable 54.
  • the cable 54 extends between a first end 56, which is fixed to the lever 45 and precisely to the end 51 of the lever 45, and a free second end 57, which is shaped for selectively engaging and releasing the main float 7 of the feeding device 2.
  • the ends 56, 57 of the cable 54 are provided with respective transverse heads 58, 59, projecting radially from the cable 54 and, for example, (but not necessarily) substantially shaped like a spherical cap.
  • the fastening body 62 has a cavity 63 which accommodates the head 58 and has a narrowing 64 through which the cable 54 is arranged and that locks the head 58 in the cavity 63; optionally, the cavity 63 communicates through the narrowing 64 with a groove 65 which houses an end portion 66 of the cable 54.
  • the fastening body 62 is integrally fixed to the end 51 of the lever 45, so as to be movable integrally with the lever 45.
  • the body 62 is formed by a piece which is distinct and separate from the lever 45 and is provided with an optionally releasable coupling 67 so as to fasten the body 62 to the lever 45.
  • the body 62 is snap fitted onto the lever 45.
  • the body 62 can be fastened in any way to the lever 45, or also form a piece or portion of the lever 45 itself, forming a monolithic piece therewith.
  • the cable 54 is inserted in a guide 68 fixed to the support structure 37 of the flushing valve 3 and extending substantially parallel to the axis X of the flushing valve 3 below the body 62.
  • the guide 68 projects laterally from an upright 69 of the support structure 37 towards the valve body 41, i.e. towards the pipe 43.
  • the guide 68 has a longitudinal groove 70, for example, substantially rectilinear and parallel to the axis X, through which the cable 54 is inserted.
  • the guide 68 and in particular the groove 70 are aligned with the groove 65 of the body 62.
  • the cable 54 is inserted in a guide 72 fixed to the support body 4 of the feeding device 2.
  • the guide 72 is located on an outer lateral surface 73 of the support body 4 and has a longitudinal groove 74, for example, substantially rectilinear and parallel to the axis A, through which the cable 54 is inserted.
  • the cable 54 has an end portion 75 projecting from the guide 72 and ending with the end 57 and cooperating with the unlocking float 55.
  • the unlocking float 55 is supported by the body 4: in particular, the float 55 is hinged to the surface 73 by a pin 76 defining a rotation axis R orthogonal to the axis A.
  • the float 55 comprises a floating case 77 and a lever 78 positioned on opposite sides of the pin 76.
  • the lever 78 protrudes from the case 77 and has a free end provided with a through hole 79, substantially orthogonal to the axis A.
  • the end portion 75 is inserted through the hole 79.
  • the end 57 is located at a height (measured parallel to the axis A) that is higher than that of the float 55 and also of a coupling seat 80 of the main float 7.
  • the coupling seat 80 is formed on a projection 81 of the float 7 and extends substantially parallel to the axis A.
  • the projection 81 extends from the float 7 to the outside of the container 16 and is flanked by the end portion 75 of the cable 54.
  • the projection 81 is movable integrally with the float 7 and parallel to the axis A.
  • the coupling seat 80 is open laterally towards the cable 54, having a lateral opening 82 facing the cable 54; and has a top edge 83 transverse to the axis A and cooperating with the head 58.
  • the cable 54 is insertable in the coupling seat 80 through the lateral opening 82.
  • the edge 83 is shaped so as to axially engage the head 58.
  • the cable 54 is preferably housed in an outer tubular sheath 85, for example made of a polymer material (plastic), which covers the cable 54 and from which the end portions 66, 75 of the cable 54 protrude.
  • an outer tubular sheath 85 for example made of a polymer material (plastic), which covers the cable 54 and from which the end portions 66, 75 of the cable 54 protrude.
  • the sheath 85 has two opposite ends housed inside the guides 68, 72, respectively, and fixed thereto, for example by interlocking i.e. by mechanical interference.
  • the cable 54 is inserted with radial clearance in the sheath 85 and slidable inside the sheath 85.
  • the cable 54 is preferably a metal cable.
  • the cable 54 is flexible but has a predetermined rigidity, such as to keep the cable 54, or at least its end portion 75 projecting from the guide 72, in a predetermined configuration with no further bending due to gravity.
  • the end portion 75 of the cable 54, projecting from the guide 72 and ending with the end 57 assumes a stable predetermined configuration in the absence of external forces and remains in this configuration without bending only by gravity.
  • the float 55 is movable (in particular, rotatable about the axis R with respect to the support body 4 of the feeding device 2) so as to move the cable 54 with respect to the main float 7 from a releasing position, in which the cable 54 does not engage the float 7, to an engaging position, in which the cable 54 engages the float 7, in particular through the end 57.
  • the float 55 is movable (rotatable about the axis R) with respect to the support body 4 for selectively assuming a first and a second operating position, which the float 55 assumes following a variation (fall) of the water level in the tank and precisely when the float 55 is sustained and not sustained, respectively, by the water contained in the tank.
  • the lever 78 and the hole 79 are substantially horizontal, i.e. perpendicular to the axis A, and the cable 54 passes through the hole 79 in a substantially vertical direction (parallel to the axis (A); and in the second operating position, which the float 55 assumes when the water contained in the tank does not reach the float 55, the lever 78 and the hole 79 are inclined with respect to the axis A and therefore the cable 54 also passes through the hole 79 in an oblique direction with respect to the axis A.
  • the float 55 by passing from the first to the second operating position, moves the cable 54 (specifically the end portion 75 of the cable 54) respectively from:
  • the main float 7 floats in the container 16 filled with water and keeps the feeding valve 6 closed.
  • the floats 23, 33 are kept lifted by the water contained in the tank, and the service hole 21 and the outlet hole 30 are open.
  • the main float 7 as it is housed in the container 16 filled with water (namely, the tank 19), does not drop directly with the decrease of the water level in the tank, but remains raised as long as there is water in the tank 19 of the container 16.
  • the float 23 keeps the service valve 22 and the service hole 21 open; the siphon system 20 does not act as a siphon (because air enters through the service hole 21).
  • the float 23 drops and closes the service valve 22 and the service hole 21, thus activating the siphon system 20. Since air cannot enter through the service hole 21, the water flows out of the discharge hole 17, thus emptying the tank 19.
  • the main float 7 drops, thereby opening the feeding valve 6; the water enters the channel 5 and through the pipe 10 fills the tank.
  • the feeding device 2 also intervenes in case of leakage of the tank, for example when a malfunction occurs in the flushing valve 3, in order to keep the feeding valve 6 closed despite the emptying of the tank, and thus avoid waste of water.
  • the siphon system 20 does not act as a siphon, since the service hole 21 is open and therefore allows air to enter the siphon system 20; consequently, the tank 19 housing the main float 7 remains full, keeping the float 7 lifted and therefore keeping the feeding valve 6 closed.
  • the main float 7 opens the feeding valve 6, in particular after the water in the tank reaches the level L2 to which the float 23 drops, and closes the service valve 22 and the service hole 21, thereby activating the siphon system 20 which empties the tank 19.
  • the water fills the container 16 and therefore also the tank 19; the main float 7 rises and closes the feeding valve 6, stopping the water from entering the tank.
  • a forced filling of the tank can be activated even when the feeding valve 6 remains closed, for example as a result of leaks in the tank, by further operating the flushing valve 3, in particular by pressing the push-button 49 acting on the slider 48.
  • the cable 54 slides inside the sheath 85 and in the guides 68, 72; the end 57 of the cable 54 is dragged downwards.
  • the float 55 is in the second operating position, as it is not supported by the water contained in the tank, and therefore the cable 54 is in the engaging position: the end portion 75 of the cable 54 axially engages the coupling seat 80 and hence the float 55.
