Abstract

The flush valve for a cistern (1) has a main valve (V) with a main valve body (3), which forms a piston, over which a discharge chamber (4) is arranged. With a first auxiliary valve (HV1), the discharge chamber (4) for rinsing release is at least partially emptied. With a second auxiliary valve (HV2), the discharge chamber (4) for a rinse interruption is floatable. The first auxiliary valve (HV1) and the second auxiliary valve (HV2) have a common auxiliary valve body (7) which releases the valve opening (68) of the first auxiliary valve (HV1) and the valve opening (6) of the second auxiliary valve (HV2) during a rinsing release. closes. Preferably, a valve seat (18) of the first auxiliary valve (HV1) and a valve seat (21) of the second auxiliary valve (HV2) are arranged on the main valve body. The drain valve can be operated with a comparatively small actuation force and small actuating travel and allows a very compact design with comparatively few components.

Description

  • The invention relates to a drain valve for a cistern, comprising a main valve having a main valve body in a valve housing, which forms a piston, via which a discharge chamber is arranged, with a first auxiliary valve, with which the discharge chamber for Spülauslösung is at least partially emptied and with a second auxiliary valve with which the discharge chamber for a rinse interruption is floatable.
  • Drain valves for cisterns have long been known. In particular, drainage valves which enable partial flushing with, for example, three liters of rinsing water have proved to be useful. In such a cistern, either a full flush or a partial flush can be selected. As a rule, two buttons are provided for flushing. Pressing one key causes a partial flush and a full flush when the other key is pressed.
  • A drain valve that allows such a two-stage flush is out of the EP 0 722 020 B became known. With this drain valve, the valve body is raised to initiate the flushing process. In a partial flush a float controls a lever which prematurely releases the valve body so that it falls onto the valve seat prior to emptying the flushing cistern. In practice, this drain valve has proven itself many times. The drain valve has the advantage that it can be built very compact. The actuating force as well as the actuating travel when opening and closing the valve but are relatively large.
  • By the DE 92 15 972 U is a generic drain valve has become known in which the Spülauslösung should be possible with a smaller actuation force. The drain valve has a main valve body, which can be lifted from its seat by actuating an auxiliary valve by means of an actuating device due to a negative water balance occurring in a relief chamber. When emptying the discharge chamber forms in this a negative pressure, which raises the main valve body in the manner of a piston. For optional partial emptying an auxiliary auxiliary valve is provided, which is at least to open briefly to flood the discharge chamber. When the discharge chamber floods, a positive water balance is formed, causing the main valve body to prematurely close. The auxiliary auxiliary valve is assigned to a partial emptying a floating body. The auxiliary valve has an auxiliary valve body, which is to move down to trigger the flushing. This is a spring tensioned. This drain valve consists of comparatively many individual parts and requires a comparatively large volume of construction, which is particularly disadvantageous in concealed cisterns.
  • By the EP 1 270 831 is a drain valve has become known, which also has an auxiliary valve and allows a release with a comparatively small actuation force. Both the opening and closing of the auxiliary valve is float controlled. The closing of the valve is delayed, which is disadvantageous.
  • The invention has for its object to provide a drain valve of the type mentioned, which allows a partial flush and can be opened and closed with the smallest possible operating force and small actuation travel and can still be built compact and with relatively small volume. The drain valve should also be reliable.
  • The object is achieved in a generic drain valve in that the first and the second auxiliary valve have a common auxiliary valve body which releases the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve closes at a Spülauslösung.
  • When the drain valve according to the invention, a separate auxiliary auxiliary valve with a corresponding second auxiliary valve body is not required. The auxiliary valve with which the discharge chamber is at least partially emptied and the second auxiliary valve, with which the discharge chamber is flooded, are operated with the same auxiliary valve body. With the same movement of the auxiliary valve body with which the valve opening of the first auxiliary valve is released, and the valve opening of the second auxiliary valve is closed. The opening of the valve opening of the first auxiliary valve and the closing of the valve opening of the second auxiliary valve can be carried out with a comparatively short stroke movement of the auxiliary valve body and thus with a correspondingly short actuating travel. This allows a much simpler and more compact construction of the drain valve. Due to the small actuating force and the small actuating travel, the drain valve is particularly suitable for a motorized operation.
  • A particularly compact design results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body. This also allows the number of items to be significantly reduced.
  • An even simpler construction results when, according to a development of the invention, the auxiliary valve body is vertically movable between the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve. Preferably, the two auxiliary valve openings are arranged directly above one another. By a comparatively small vertical movement of the main valve body, the first auxiliary valve can be opened and the second auxiliary valve can be closed. As a result, a particularly short actuation path is possible.
  • Preferably, the first auxiliary valve is opened by lifting the main valve body and closed with the same stroke, the valve opening of the second main valve body.
  • According to a development of the invention, it is provided that the main valve body is held in its basic position by a first pawl down and that this pawl is pivoted at a Spülauslösung so that it releases the main valve body.
  • According to a development of the invention it is provided that a second pawl is arranged on the auxiliary valve body, with which the auxiliary valve body is connected to the main valve body. This allows a particularly reliable opening of the valve opening of the first auxiliary valve.
  • According to a development of the invention, it is provided for triggering the partial flush that the second latch cooperates with a float, which releases the auxiliary valve body upon reaching a predetermined Spülwassemiveaus.
  • A particularly cost-effective production and a compact construction results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body.
  • Further advantageous features emerge from the dependent claims, the following description and the drawings.
  • An embodiment of the invention will be explained in more detail with reference to the drawing. Show it:

  • 1 shows sections of a cistern 1, which may be formed as usual and having an actuating device, not shown here. The cistern 1 has at a bottom 11 a conventional outlet nozzle 12, in which a drain valve 10 is inserted. In the cistern 1 according to Figure 2 rinse water 66 is stored. The volume of the rinse water 66 is, for example, with a full cistern 1, six or nine liters. FIG. 2 shows the water surface 46 when the cistern 1 is filled. The drain valve 10 is used to empty the cistern 1, where it is opened, for example, to actuate a button, not shown here and rinse water flows through the outlet nozzle 12 in a toilet bowl, not shown here. The flushing takes place as mentioned, for example by pressing a button. Basically, however, a non-contact motor control is conceivable.
  • The drain valve 10 has a valve housing 2, which has a valve opening 5. Over this valve opening 5 a plurality of side openings 15 are arranged in the valve housing 2, through which rinse water 66 can flow with open valve opening 5 in the outlet pipe 12 and thus in the toilet bowl.
  • The valve opening 5 forms a main valve body 3 with a main valve V. The main valve body 3 has a valve plate 14 which rests on a valve seat 13 in FIG. The main valve V is closed in Figures 1 to 3.
  • The valve body 3 has at its periphery a piston ring 16 which bears against an inner side 17 of a discharge chamber 4 in a vertically displaceable sealing manner. The main valve body 3 seals with the sealing ring 16 the discharge chamber 4 down from. It forms a piston which is vertically movable between the lower position shown in FIG. 1 and an upper position shown in FIG. 4 with the stroke H3 shown in FIG.
  • On the main valve body 3, an auxiliary valve body 7 is mounted, which rests in Figure 1 on a valve seat 18 of a first auxiliary valve HV. Above this valve seat 18, a second valve seat 21 of a second auxiliary valve HV2 is arranged. This second valve seat 21 is formed by a pipe 67, which is integrally formed on the main valve body 3 by webs not shown here and has an upper edge 34. The tube 67 is open at an upper edge 34 and has a channel 6, which forms the valve opening of the second auxiliary valve HV2 at a lower end. The auxiliary valve body 3 is thus the common valve body for the first auxiliary valve HV1 and the second auxiliary valve HV2. The auxiliary valve body 7 has a valve disk 19 which rests on a valve seat 18 when the auxiliary valve HV1 is closed. In FIG. 1, the first auxiliary valve HV1 is closed and the second auxiliary valve HV2 is opened. The auxiliary valve body 7 is movable between the lower position shown in Figure 1 and the upper position shown in Figure 3 with a comparatively short stroke. This stroke is much shorter than the stroke H3 of the main valve body 3. In addition, the force required to lift the auxiliary valve body 7 is comparatively small. In the position shown in FIG. 3, the second auxiliary valve HV2 is closed, but the first auxiliary valve HV1 is opened.
  • The main valve body 3 has on an upper side 44 at least one control opening 20 which is open towards the relief chamber 4 and which connects the relief chamber 4 to an opening 68 of the first auxiliary valve HV1 when the first auxiliary valve HV1 is open. This opening 68 leads into the main valve opening 5. When the first auxiliary valve HV1 is opened, water present in the relief chamber 4 can flow out through the control opening 20 into the opening 68 and thus into the outlet connection 12.
  • The pipe 67 of the main valve body 3 projects beyond the valve housing 2 when the main valve V is closed, as FIG. 1 shows. In this tube 67 of the auxiliary valve body 7 is mounted. This auxiliary valve body 7 also projects beyond an upper end Valve housing 2 and has an overflow channel 22. The auxiliary valve body 7 forms in this case an overflow pipe, which determines the maximum filling of the cistern 1. However, the overflow channel 22 can also be arranged in a manner known per se outside the drainage valve 10. The auxiliary valve body 7 is thus not necessarily an overflow pipe.
  • On the valve housing 2, a float 69 is mounted, which forms an air chamber 26 and a water chamber 27 in a housing 25. These two chambers 26 and 27 are separated from each other by a bottom wall 32. In the air chamber 26 is always filled with cistern air and in the water chamber 27 always water. The air in the air chamber 26 causes a buoyancy force according to arrow 28 and the water in the water chamber 27 at a partial emptying of the cistern (Figure 5) a weight according to arrow 29. At the float 69, a rod 23 is fixed, the down in a Chamber 70 of the valve housing 2 protrudes. On the rod 23, a stop cam 24 is formed, which allows a maximum stroke H1. FIG. 1 shows the float 69 in the lower position. Starting from this position, the float 69 can be lifted with the stroke H 1 by the buoyancy force of the air chamber 26.
  • At the float 69, a cam 30 is mounted, with which the float 69 according to Figure 1 with empty or partially empty cistern 1 on a two-armed first pawl 8 loads. The pawl 8 is pivotally connected to the valve housing part 2 a with the valve housing 2 and surrounds the tube 67 in a semicircle. At the pawl 8, two cams 33 are mounted, which cooperate with the main valve body 3. For this purpose, the main valve body 3 has on its outer side two opposite vertically extending ribs 71 and 71 '(FIG. 6), which have an upper edge 72 and 72', respectively, against which a cam 33 according to FIG. In the position of the first pawl 8 shown in Figure 1, the main valve body 3 is locked in the closed position shown by the two cams 33. The main valve body 3 can thus not be raised. The illustrated position of the first pawl 8 is held in this position by the weight of the float 69. If the flushing cistern 1 according to FIG. 2 is filled with flushing water 66, the float 69 is shown in FIG raised to the highest position and thus the latch 8 relieved of the weight of the float 69. When emptying the cistern 1, the float 69 drops down again and loads with the cam 30 on the first pawl eighth
  • At the auxiliary valve body 7, a second also two-armed in the directions of the double arrow 65 pivotable pawl 9 is mounted, which surrounds the auxiliary valve body 7 in a semicircular shape and is connected thereto via a rotary joint 38. On two horizontal arms 39 of the pawl 9, a respective driver 40 or 62 is arranged, on which a pull rod 41 or 60 (FIG. 6) engages. The drivers 40 and 62 each form a pin which engages in a slot 42 of the tie rod 41 and 60, respectively. The drawbar 41 and 60 can be raised with an actuating device, not shown here, for example with an actuating lever in the direction of arrow 43 and 63, respectively. On a downwardly directed arm 35, a shoulder 36 is arranged, which rests with raised auxiliary valve body 7 at the edge 72 and 72 'of the rib 71 and 71' instead of the cam 33, as Figure 3 shows. Is pulled on the pull rod 41 and 60, it exerts on the second pawl 9 a torque, which acts with respect to the rotary joint 38 in Figure 1 in the counterclockwise direction. By this torque, the first pawl 8 is rotated counterclockwise about the pivot 37 during lifting of the auxiliary valve body 7 and thus the two cams 33 are pushed away from the edge 72. When the auxiliary valve body 7 is raised so that the main valve body 3 is locked to the auxiliary valve body 7.
  • About the discharge chamber 4, a further chamber 73 is arranged, which has according to Figure 7, an opening 75 which is closable with a slide 76. In this chamber 73, a float 50 is arranged according to Figures 6 and 7, which is mounted pivotably about a pivot 53 on the valve housing 2. The float 50 is a so-called Kippschwimmer and has a lower air chamber 55 and an upper water chamber 58. The chambers 55 and 58 are separated by a bottom wall 57 from each other. The chamber 73 is filled with filled cistern according to Figure 2 with water. The air in the air chamber 55 causes a buoyant force according to arrow 56 and the water in the water chamber 58 at empty chamber 73 a weight according to the Arrow 59. When filled chamber 73 acts on the float 50, a clockwise torque according to double arrow 54th
  • At the float 50, a forwardly projecting nose 51 and an upwardly projecting stop cam 52 are arranged. The stop cam 52 cooperates with the second pull rod 60. This pull rod 60 is provided for a full flush and can be raised in the direction of arrow 63. The second pull rod 60 has a slot 61 into which the catch 62 of the second pawl 9 engages. If the pull rod 60 is raised in the direction of the arrow 63, the pull rod 60 engages the driver 62 and thus pulls the main valve body 7 upwards. As when lifting with the tie rod 41 is applied to the pawl 9 as shown in FIG. 6 in the counterclockwise direction about the pivot 38, a torque through which the pawl 8 is pivoted. The pawl 8 rests simultaneously on the rib 71 and on the second opposing rib 71 '. The rib 71 'also has an upper edge 72' on which the pawl 8 rests. The first pawl 8 and the second pawl 9 thus extend arcuately around the auxiliary valve body 7. In the figure 1, one side and in the figure 6, the other side is visible.
  • If the second pull rod 60 is raised, the tongue 74 formed on the lower end of the second pull rod 60 is raised at the same time. In the basic position, this tongue 74 abuts the stop cam 52 according to FIG. 6 and thus prevents the float 50 from tilting about the pivot joint 53. When the second pull rod 60 is lifted, the tongue 74 is raised above the stop cam 52 according to FIG. 7 and thus the float becomes 50 free and can pivot about the pivot 53 in a clockwise direction due to said torque. As a result, the nose 51 engages with a recess 64 of the rib 71 '. This causes a locking of the raised main valve body 3. The float 50 remains in this position as long as there is water in the chamber 73 and thus said torque is applied.
  • The outflow of the water from the chamber 73 can be regulated with the slide 76 shown in FIG. This slider 76 is located in front of the opening 75 and can be moved in the directions of the double arrow 77. If the slider 76 is in the position shown in Figure 7, the opening 75 is closed. If the level of the rinse water 66 drops below the level of the opening 75, the water in the chamber 73 remains until the cistern 2 is substantially emptied. With the slide 76 raised, however, the chamber 73 empties relatively quickly, so that the chamber 73 is emptied before the cistern 1 is emptied. If the chamber 73 is emptied, said torque is no longer present and the float 50 tilts due to its weight immediately in the position shown in Figure 6. The main valve body 3 is thereby released and falls due to its own weight immediately on the valve seat 13, whereby the main valve V is closed. The auxiliary valve body 7 is unlocked prematurely and also falls due to its weight down and thus closes the first auxiliary valve HV1. On the slider 76 so that the full amount can be regulated at a flush. For example, the full amount can be set to six liters or nine liters. This is a default setting, which is usually not changed after the installation of the cistern 1. The cistern 1 is thus installed for a full flush with, for example, nine liters or for a full flush with six liters.
  • The operation of the inventive drain valve 10 will be explained in more detail.
  • Before triggering a flushing the cistern 1 is filled with rinse water 66 according to FIG. Due to the buoyancy of the water, the float 69 is raised. The main valve body 3 is loaded in the closed position by the water 66. The discharge chamber 4 is also filled with water, which also rests on the main valve body 3.
  • To trigger a partial flush with, for example, three liters of water, the pull rod 41 is raised in the direction of arrow 43. The comparatively small force for lifting the drawbar 41 can be done by hand or with a motor, not shown. By raising the pull rod 41, the auxiliary valve body 7 is raised and, finally, in the raised position according to FIG. 3, the first pawl 8 is pivoted by a pivoting movement of the second pawl 9. The auxiliary valve body 7 is thus locked with the main valve body 3 and at the same time the locking of the main valve body 3 is lifted to the valve housing 2. During said raising of the auxiliary valve body 7, the first auxiliary valve HV1 is opened and immediately thereafter the second auxiliary valve HV2 is closed with the same stroke. If the first auxiliary valve HV1 is opened, according to FIG. 3, water flows from the relief chamber 4 downwards into the outlet connection 12 in the direction of the arrow 47. This results in a differential pressure at the main valve body 3, which is moved upwards into the position shown in FIG. Characterized the main valve V is opened and the water 66 flows according to Figure 4 through the openings 15 in the direction of arrows 48 from the cistern 1 in the toilet bowl.
  • When lifting the main valve body 3, the auxiliary valve body 7 is at the same time, since it is locked as mentioned with the main valve body 3 by the second pawl 9. Since the rinse water 66 flows out of the cistern 1, the water surface 46 correspondingly decreases. If this water surface 46 reaches the float 69, the buoyancy of the float 69 subsequently decreases and the latter sinks accordingly. Finally, the cam 31 presses on the second pawl 9 and pivots it clockwise into the position shown in Figure 5. The cam 30 is now against the first pawl 8 and presses it against the ribs 71 and 71 '. The auxiliary valve body 7 is now unlocked and falls immediately due to its own weight on the valve seat 18. As a result, the first auxiliary valve HV1 is closed. Through an upper opening 45 of the channel 6 flows from the top according to Figure 5 in the direction of arrow 49 rinse water 66 in the control port 20 and finally in the discharge chamber 4. This water rests on the main valve body 3, which thereby immediately falls down on the valve seat 13 , As a result, the main valve V is closed. However, the cistern 1 is only partially emptied, since the water surface 46 has lowered until approximately in the area of the float 69. In the cistern 1 thus remain, for example, still six liters of rinse water. If the main valve body 3 is located on the valve seat 13, the auxiliary valve body 7 is also located in the lower position shown in FIG. By the pressure of the float 69 on the first pawl 8, this pawl 8 is pivoted back into the position shown in Figure 2, in which the main valve body 3 is locked to the valve housing 2. With the sinking of the water surface 46 is not one here shown per se ordinary inlet valve open and thus rinse water flows into the cistern 1 and this is finally refilled until the water surface 46 reaches approximately the level shown in Figure 2. The cistern 1 is thus again in the starting position shown in Figure 2 and thus ready for further flushing.
  • For the initiation of a full flush, the second pull rod 60 is raised in the direction of arrow 63 according to FIG. The purge is thus triggered as explained above, since in this case the main valve body 7 is raised and thus the first auxiliary valve HV1 is opened and the second auxiliary valve HV2 is closed. At about the same time, however, the float 50 is unlocked and this now tilts in Figure 6 clockwise about the axis of the pivot joint 53. If the main valve body 3 is raised by the stroke H2 (Fig. 6), the float 50 tilts further in the same direction and the nose 51 finally engages in the recess 64, as shown in Figure 7. The main valve body 3 is now locked to the valve housing 2. The swimmer 69, which sinks after the rinsing release, closes the auxiliary valve HV1 as in the case of a partial rinse, but remains ineffective and can not interrupt the rinsing. If the slider 76 is raised and thus the opening 75 free, the float 50 is pivoted as explained above before a complete emptying of the cistern 1 back into the position shown in Figure 6 and lifted the lock of the main valve body 3 and thus interrupted the flushing. In this case, a full flush is also carried out, but only with six instead of, for example, nine liters of rinse water 66th
