Definitions

  • the present invention relates to a device for controlling the discharge valve of a lavatory flush tank, and in particular to a water-saving discharge valve control device enabling both total and partial discharge of the water in the tank.
  • Discharge valve control devices are normally required to so close the valve as to discharge a given amount of water, usually all the water in the tank, and provide for delaying closure of the valve in various ways by exploiting the suction of the outgoing water.
  • EP-A-10 945 relates to a device according to the preamble of claim 1, wherein the overflow discharge tube comprises an annular element for closing the discharge valve, so that the overflow discharges via the tube and the annular element; the discharge tube is fitted with a first annular float; and a second float is provided close to the bottom of the tank, and is fitted to a lever extending radially with respect to the discharge tube, and having means for connection to a control member.
  • the second float is normally locked, so that the discharge tube closes the discharge valve when the water in the tank falls to a given level corresponding to the position of the first float.
  • the second float prevents the control device from being restored to the closing position, so as to delay closing of the valve until the level of the water falls below the second float, and so discharge all the water in the tank.
  • This device presents the drawback of being fairly bulky, on account of the float, as well as being unreliable on account of the connection between the lever of the second float and the control member.
  • DE-A-3 121 625 relates to a further control device enabling both total and partial discharge of the water in the tank, and wherein the valve closing element is fitted to a first cylindrical float surrounded by a hollow cylinder, which is fitted at the top with a second annular float normally locked by a hook to discharge all the water in the tank.
  • the hollow cylinder closes the drain when the level of the water lowers the second float, thus preventing the water from being discharged.
  • This device presents several drawbacks, by requiring a separate overflow discharge tube, separate means for guiding the hollow cylinder, and a complex mechanism for controlling the first float and the hook locking the hollow cylinder.
  • FR-A-2676480 discloses a device in which two floats are positioned in series above each other and slide along a discharge tube; this device presents the drawbacks of requiring two different floats and of having relatively high overall dimensions.
  • a device for controlling the discharge valve of a lavatory flush tank with the features of claim 1.
  • Number 5 in Figure 5 indicates a lavatory flush tank comprising a standard cock (not shown) for connection to the water supply pipe; a standard float (not shown) for controlling the cock; and a bottom wall 6 with a hole 7 in which is fitted a device for controlling discharge of the water and indicated as a whole by 8.
  • the components of device 8 are normally made of rigid plastic material, so that, hereinafter, the component material is only specified when other than rigid plastic.
  • Device 8 ( Figure 1) comprises a discharge fitting 9 having an externally-threaded bottom portion 11, a flat shoulder 12, and a top portion 13 larger in diameter than bottom portion 11.
  • Portion 11 is inserted inside hole 7 via the interposition of a seal 14, and is fitted to the bottom of tank 5 by a threaded ring nut 16.
  • Portion 13 is connected to shoulder 12 by four axial segments 17 ( Figure 4) defining four openings 18 enabling water to flow from tank 5 into portion 11.
  • Portion 13 comprises an L-shaped slot 19 ( Figure 2), which is engaged bayonet-fashion by a radial pin 20 on an annular support indicated as a whole by 21 ( Figure 1) and which rests on an annular shoulder 25 of portion 13.
  • Figure 2 By means of a cylindrical outer wall 23, a cylindrical inner wall 24 and a bottom wall 26, support 21 defines an annular chamber 22 closed at the top by a removable cover 27, which is defined inwards by an annular lip 28 larger in diameter than inner wall 24.
  • Cover 27 comprises an opening 29 through which water flows into chamber 22; and bottom wall 26 comprises a calibrated hole 31 by which chamber 22 is emptied slowly.
  • a normal overflow discharge tube 32 slides inside wall 24, and comprises a bottom shoulder 33 defining the bottom end 34 of tube 32.
  • End 34 comprises a number of axial ribs 30 on which rests a ring nut 35 inserted inside end 34; and ring nut 35 comprises a bottom flange 36 facing a similar flange 37 of a rigid ring 38 having a diametrical dividing wall 40 ( Figure 4) with a central hole 39.
  • Ring 38 comprises four elastic tabs 41, each with a tooth 42, which clicks on to shoulder 33 to grip between flanges 36 and 37 an element for closing the discharge valve; which element comprises a ring 43 of elastic material, which rests against a projection 44 located on the upper surface of shoulder 12 of fitting 9, and defining the seat for the discharge valve of tank 5.
  • Beneath flange 37, ring 38 comprises a conical lip 45 defined by an annular rib 46, and forming a seat for a plugging element comprising a disk 47, which plugs seat 45, and hence the bottom end 34 of tube 32, so that tube 32 acts as a first float for controlling the return movement of ring 43 into the position closing the discharge valve.
  • Disk 47 is integral with a central rod 48 guided by hole 39 in dividing wall 40, and fitted removably at the top end with a supporting element 49 for a helical compression spring 51, the other end of which rests against the upper surface of dividing wall 40.
  • Disk 47 also comprises a calibrated hole 50 allowing the passage of a certain amount of water, and spring 51 is so sized that disk 47 is detached from seat 45 when the column of water inside tube 32 exceeds by a given amount the maximum level H ( Figure 5) of tank 5.
  • discharge tube 32 comprises an outer radial tab 52 with a vertical slot 53, which is engaged by a pin 54 fitted to a plate 56; and plate 56 comprises a bent tab fitted to a tie 57, which is raised to lift tube 32 and open the discharge valve.
  • Chamber 22 houses a second float comprising an annular chamber 58 enclosed in an open-bottom casing 59, and which may house a ring made of material of a low specific weight.
  • the inner wall of casing 59 projects upwards into a sleeve 61, which is guided between wall 24 of support 21 and inner lip 28 of cover 27, so that second float 58 is located a minimum radial distance from tube 32.
  • the hydrostatic thrust of float 58 is greater than the weight of tube 32.
  • Sleeve 61 comprises a slightly smaller-diameter top portion 62, which slides on the outer surface of tube 32; and tube 32 comprises two radial appendixes 63, each with a number of ribs 60, which are engaged by the top edge of portion 62 of sleeve 61.
  • cover 27 comprises a pair of radial tabs 64 connected by a trapezoidal-section bar 66, which forms a fixed stop element for a hook element 67 fitted to sleeve 61.
  • hook element 67 comprises a lever 68 having a hook-shaped bottom end 69 for engaging bar 66.
  • Lever 68 pivots on a pin 71 fitted to a pair of radial ribs 72 integral with sleeve 61, is pushed clockwise by a compression spring 73 housed in a seat 74 on lever 68 and resting against a depression on portion 62, and is connected in articulated manner by a pin 77 to a control tie 78, which is raised to release hook-shaped end 69 from bar 66 and raise sleeve 61 together with float 58.
  • Tie 78 may be provided with a weight 79 to assist, or even replace, spring 73.
  • Cover 27 is connected by two vertical bars 75 ( Figures 3 and 5) to an upper fitting 76 connected in any known manner to a hole 88 formed in the usual cover 80 of tank 5 and coaxial with hole 7 in bottom wall 6.
  • Fitting 76 comprises a pair of parallel wings 85 extending downwards and fitted with two parallel pins 86 and 87 on which pivot two transmission levers 83 and 84 connected in articulated manner to ties 57 and 78.
  • Ties 57 and 78 are located in a substantially radial plane with respect to tube 32, so that levers 83 and 84 are movable in said radial plane, and each present a control arm 89, 90 extending towards the axis of fitting 76.
  • Push-button 81 is fitted to a respective push rod 92 terminating at the bottom with a central cylindrical element 93, which acts on arm 89 of tie 83; and push-button 82 is fitted to a further push rod 94 terminating at the bottom with a hollow element 96 coaxial with element 93, and which acts on arm 90 of tie 84; for which purpose, arm 90 is in the form of a fork, the branches of which are located on either side of arm 89.
  • the control device operates as follows.
  • tank 5 When idle, tank 5 ( Figure 5) is filled with water up to level H defined by the usual float closing the supply cock; overflow discharge tube 32 is in the lowered position shown in Figure 5, wherein ring 43 rests on projection 44 so that the discharge valve is closed; and the water in chamber 22 pushes float 58 upwards, so that the hook-shaped end 69 of lever 68 is arrested against bar 66.
  • tie 78 draws sleeve 61, and with it tube 32, positively upwards to open the discharge valve as shown in Figure 6, so that tube 32 begins to float, while float 58 is pushed hydrostatically against cover 27 to help raise tube 32. At this point, the water flows towards the drain, but when the hydrostatic thrust on tube 32 equals its weight, tube 32 is prevented from moving down by force of gravity by still being maintained in the raised position by float 58.
  • the advantages of the control device according to the invention will be clear from the foregoing description.
  • using the overflow discharge tube 32 as a first float, and a second float 58 concentric with and at a minimum distance from tube 32 provides for greatly reducing the size of the control device fitted inside tank 5.
  • the hydrostatic thrust of the second float 58 reduces the pressure required to operate push-button 82.
  • slowly emptying chamber 22 housing the second float 58 ensures tank 5 is emptied completely.
  • the float (32, 47) controlling the valve may be separate from overflow discharge tube 32; and, as opposed to being threaded, portion 11 of fitting 9 and ring nut 16 may be smooth, click-on types.
  • discharge tube 32 may comprise axial ribs to reduce sliding friction; disk 47 need not necessarily comprise hole 50; and some of the components of the control device may be made of metal alloy as opposed to plastic material, and be connected otherwise than as described.
