Device for emptying and automatically filling a water reservoir, in particular Toilet cistern

The invention relates to a device for emptying and automatically filling a water storage tank, in particular a toilet cistern, comprising a water tank with a floor outlet serving for emptying, furthermore one arranged above the floor outlet, movable control member, which on the one hand discharges any excess amounts of water through the floor outlet Overflow pipe and, on the other hand, from a lower end to it attached, the floor outlet in the storage state of the device covering closure body and which to its effective emptying movement with a manually operated from the outside Trigger member is connected, and finally one in particular the overflow pipe of the control member during its movement supporting guide.

In such water tanks that are used as toilet cisterns a sufficient amount of water, independent of the water line pressure, should be used for flushing purposes as required To be available. In addition, the water storage should be after Refill the rinsing process automatically to a certain amount of water to keep ready for the next rinse. In addition, the water reservoir will overflow, for example in the event of a defective Safe to avoid inlet valve.

It is known to use water storage tanks of the type mentioned at the outset, which consist of a water tank, in order to meet these requirements with a floor outlet and a device arranged therein for emptying and automatically filling the water tank exist. A closure body located above the bottom outlet is connected to an overflow pipe, which at the same time serves as a control element for emptying the water tank. The closure body is within a also the bottom outlet covering bell housing provided with passage openings arranged. The overflow pipe connected to the closure body emerges from a guide sleeve connected to the bell housing and protrudes over the through a to the inlet valve acting swimmers set the water level in the water tank. The overflow pipe has protruding from the water End of receiving means for a release lever, which by a release member led out of the water tank of Hand 2u is operated. When the release member is actuated, the closure body is lifted over the overflow pipe attached to it and the water in the box can drain through the slots in the bell housing and the bottom outlet. Hachdem that Water has run out of the water tank, the closure body falls, together with the overflow pipe, due to its own weight into its closed position and seals the floor outlet from the interior of the water tank. When the water level is falling A float that sinks with it opens the inlet valve until the Schwiitsner, who is carried along with the rising water level the inlet valve shuts off again. During the rinsing process the closure body cannot close the bottom outlet, since it floats, so to speak, on the outflowing water and only then falls back into its closed position when öas all of the water has drained. This means that the entire amount of stored water drains off with each flushing process. In In many cases, however, a much lower rinse would be required

Enrich the amount of water a-a. The unavoidable, quantitatively un-?

influenceable, but in many cases not required individual full flushes add up over a longer period of time

Period to considerable amounts of water. Now that the prices for f

Water taken from the mains and also for the>

Sewer returned water in the last side constantly \

have risen, dishwashing costs represent a considerable part

i. of cost accounting. Apart from the high costs, f

a considerable amount of water is wasted.

The invention is based on the problem of the amount of rinse water of water storage tanks to adapt to requirements and, in addition to the necessary full flushing, flushing with smaller amounts of water to enable.

According to the invention, this object is achieved in that the control element is optionally either in only one partial emptying the water tank executing economy tax position or a full emptying effecting full tax position can be brought. In the concrete implementation of the invention there are several possibilities, each of which has its own particular advantages brings. This is explained in more detail in the further claims and in particular in the drawings and the description.

The advantages achieved by the invention are that in addition to the full flushing required if necessary, also the Requirements adaptable partial flushing are possible, so that the water consumption can be reduced considerably and thereby a Cost savings can be achieved. In addition, the water storage according to the invention can be used during the due to prolonged dry periods, occurring water scarcity and an associated water rationing use.

The water tank 10 has a bottom outlet 11 which is overlapped by a bell housing 56 provided with outlet sockets 57. The BoQenauslauf 11 can be covered within the bell housing 56 by a closure body 13, which susainmen with the upper course pipe 15 forms a control member 12. The closure body 13 is provided at its end facing the floor outlet 11, for example, with an elastic sleeve 14 which seals the interior of the water tank 10 against the floor outlet 11 the opening is connected to a guide 22 which comprises the overflow pipe 15. In the present case, the guide 22 is designed as a sleeve 23 and extends upwards from the bell housing 56 to above the maximum water level in the water tank 10. At the upper end 24 of the sleeve 23, a bearing 25 is fixedly arranged. This bearing 25 receives a pawl lever 27 which, in the present exemplary embodiment, is designed angularly and has a pawl 28 at its lower end. The upper arm of the ratchet lever 27 is connected to a release lever 29 via a tab 33 provided with an elongated hole 34, which in turn can be actuated via the release element 30. The pawl 28 engages in the rest position of the pawl lever 27 in a groove 21 of a float 19 surrounding the sleeve 23 and holds the float as long as the release member 30 has not been actuated at the predetermined height, even when the water level _{f is} falling on the sleeve 23. The overflow pipe 15, which is arranged to slide longitudinally in the sleeve 23, is provided with a stop 16 emerging from the sleeve 23, which in the present embodiment according to FIG. The upper run pipe 15 has at its upper end a bracket 18 which projects beyond the sleeve 23 and is gripped from below by a release lever 31. The release lever 31 is also connected to a release element 32 which is led out of the water tank 10. The one connected to the ratchet lever 27

7600907 05/20/76

binding release lever 29 grips below the Äusiösehebels 31 into the bracket 18.

For a full flush, the release lever 31 is pivoted by actuating the release member in such a way that it acts as a control member

12 acting overflow pipe 15 over the bracket 18 within the Sleeve 23 is pulled up so that the one with the overflow pipe connected closure body 13 lifts from the bottom outlet 11 (Figure 2). The floor outlet 11 is released and the entire im Water tank 1Q located can now drain away.

So that the closure body connected to the overflow pipe 15 cannot fall back into its closing division due to its own weight after releasing the release element 32, the closure body 13 is preferably bell-shaped and has an inwardly curved one at its lower end Cuff 14 on. The in the bell-like closure body 13 existing air cushion gives the closure body 13 such buoyancy that it floats on the outflowing water and the bottom outlet 11 keeps open until all the water has drained off. Only then does the closure body fall

13 together with the overflow pipe 15 in its closed position the floor outlet 11 back. Along with the sinking A known float 58 also moves down the water level and, when it moves, opens a water tank Located inflow valve 59, so that the water tank 10 can be filled again after the water has drained. When the water until the height in the water tank 10 has risen to a level corresponding to a full flush, the float 58 blocks the inflow valve 59 in a known manner again. In the event of a deficiency in the inflow valve 59 the water will not overflow from the water tank 10 because the water level rises when the water level rises through the upper end 24 of the sleeve 23 and the overflow pipe 15 can drain. In the case of a full flushing caused by the release member 32, the position of the release lever 29 remains unchanged, so that the float 19 in its on the sleeve 23 through the ratchet lever 27 remains fixed position.

For partial flushing, the overflow pipe 15 is raised together with the closure body 13 by actuating the release member 30 and the release lever 29 connected to it, so that it is also in this! Case for the water to flow off through the drainage slot 57 of the bell housing 56 and out of the floor outlet 11. When the release lever 29 is raised, the pawl lever 27 is pivoted at the same time, as a result of which the pawl 28 is pulled out of the groove 21 of the float 19. The float 19 now sinks together with the falling water level and hits with its impact surface 20 on the pin 17 protruding from the sleeve 23 as a result of the floating effect of the closure body in the upper section of the slots 26 (FIG. 3). Since the water continues to flow out at this moment, the float 19 continues to sink. He takes the pin 17 in the direction of the arrow and overcomes the buoyancy of the closure body 13 with partial cancellation of his own buoyancy and pushes it back into its closed position. The drainage of the Viasser is thus stopped and only a partial amount of the water stored in the water tank 10 has flowed away. This partial amount can be predetermined by the height of the stop 16 arranged aia overflow pipe! 5 and the pins 17 forming the stop 16 can be connected to the overflow pipe 15 in such a position that, for example, half or a third of the stored amount of water or any Partial water can flow away "If the release member 3G is released while the partial amount of water is being removed, the release lever 29 falls back into the position shown in FIG 19 into it. After the amount of textile water has drained off, the water tank 10 is refilled with water via the inflow valve 53 up to the spexcher level. Together with the rising water level, the float 19 also rises again

upwards and pushes the pawl lever 27 out of its path of movement via the run-up bevel of the pawl 28, the pawl 28, after the collar of the float has moved past the pawl, falls back into the groove 21 of the float and this on the sleeve 23 holds on. Through the elongated hole 34 located in the] tab 33, the ratchet lever 27 can

j perform the movement described above. j

Both the closure body 13 and the guide 22 can be formed in a fona other than the one shown, for example being. So the closure body could also consist of a hollow annular disc, the cavity of which in the storage state for example through the lower end of the overflow pipe with the air in the drain is in connection * The guide 22 also needs not to be a sleeve 23, as in the example shown, but it is conceivable to use a guide cage or guide webs to use.

In another exemplary embodiment shown in FIG the control member 12 consists of two sub-control members 35 and 36 arranged one above the other in a tiered manner. The upper sub-control member 35 consists of an overflow pipe 3S and a Closure body 40, while the lower partial control member 36 also consists of an overflow pipe 39 and a closure body 41 is formed. The inlet opening 37 of the lower overflow pipe 39 also serves as an outlet opening for the Partial emptying of the amount of water flowing out. The inlet opening 37 is through the closure body 40 of the upper part control glxedes 35 removable. For this purpose, the overflow pipe 39 des Lower part control glxedes 36 are provided with a collar 61 on which an annular seal 62 of the closure body 40 supports. To guide the upper Teilsteuerglxedes 35 is on the bell housing connected to the bottom of the water tank 10

7600907 05/20/76

56 a further bell housing 63 is placed, which likewise has drainage slots 64 on its circumference. Also the bell housing 63 has on its upper part an opening for the passage of the overflow pipe 38, which is connected to the Housing bell 63 connected guide sleeve 65 is enclosed. The upper end of the overflow pipe 38 is provided with receptacles 47 for the fork of a release lever 43 is provided. For assembly reasons, the receptacles 47 are to be attached to an example of the overflow ^ for pipe 38 screwed pipe section attached.

For partial emptying this can be seen from FIG Device is raised in the manner described above, the release lever 43, whereby the with the overflow pipe 38 connected closure body 40 of collar 61 of the lower overflow pipe 39 lifts off. Here, too, there is water at the out-fix again the same floating effect of the closure body 40, which only lowers again when the water level is about has sunk to the level of the collar 61 of the lower overflow pipe 39.

Complete emptying by means of the d shown in FIG. Device can be achieved by the intended

Release lever 42 is raised. This release lever 42 is connected to a release rod 44 which has a at its Dnterende Has driver 46, which one with the lower overflow pipe 33 connected stop 45 engages behind »When lifting the Release lever 42 is raised via the release rod 44, the lower part control member 36, so that the closure body 41 from Floor outlet 11 lifts off. Since the closure body ex 40 on the Collar € 1 of the lower overflow pipe 39 rests, the upper part control member 35 is also lifted without function. Also at Closure body 41 occurs the same prescribed Schwinaa _ effect on, so that the floor outlet 11 remains open as long as

j until in this case all the water from deia water & asten 10

has expired and thus a complete emptying has been achieved.

Both a full and a partial emptying with only a single release lever can be achieved if, for example, the release rod 4 4 is provided at its lower end with a pair of drivers. A stop (not shown) would then also have to be provided in the overflow pipe 38 of the upper part control member 35, against which the uppermost driver (not shown) of the release rod 44 first comes to rest. In this position of the release rod 44, its lower driver would not yet rest against the stop 45 of the lower overflow pipe 39, but would still have a certain distance therefrom. When the release rod 44 is pulled further upwards, the upper part control member 35 first opens in that its locking body 40 lifts off the collar 61 of the lower part control member 36. In the case of a partial flush, the trigger rod 44 does not need to be actuated any further. However, when a full flush is to be effected, the trip bar 44 is further pulled upwardly, so that their is lower catch 46 with the stop 45 into contact and also the lower part of the control member and thus its closing body 41 lifts from the bottom outlet. 11 In the case of a full flush, a small amount of water would initially be released by the upper part of the control element, but this is insignificant insofar as continuous flushing is made possible until the water tank is completely emptied.

In the solution shown in FIGS. 7 and 8, the partial control elements 35 and 36 arranged one above the other are nested one inside the other in some areas. The invention is designed here as a combined push-pull flushing device. The lower part control member 36 again consists of the overflow pipe 39 and the closure body 41. At its upper end, the overflow pipe 39 is provided with a collar 51 facing the inside of the pipe, in which a valve bore 49 is arranged. The valve bore 49 has a larger diameter than the outer diameter of the one consisting essentially of the overflow pipe 38

Upper part control member 35 * At the lower end of the overflow pipe 38 is provided with a sealing ring 52 closure part 48. In addition, a ring 53 is firmly connected to the outer jacket of the overflow pipe 3S at a distance from the Dnterende of the overflow pipe 38. Between this ring 53 and the collar 51 of the lower overflow pipe 39, a pressure accumulator 50, which is preferably designed as a compression spring, is arranged within the guide sleeve 66 connected to the housing bell 56. The sealing ring 52 is normally pressed against the valve bore 49 by the pressure accumulator 50 , so that the annular channel surrounding the overflow pipe 38 in the collar 51 is normally closed. The overflow pipe 38 is drawn together at its upper end, for example like a funnel, and is led out of the water tank 10 in an extension 54. Below this extension 54, the overflow pipe 38 is provided with passage openings 67 for the purpose of water overflow. The upper end of the extension 54 protruding from the water tank 10 has a handle 55. If this handle 55 is now pressed, the closure part 48 at the lower end of the overflow pipe 38 releases the valve bore 49, whereby the water in the water tank in the storage position through slots in the guide sleeve 66 of the bell housing 56, through the annular channel of the valve bore 49 in the direction of the arrow 69 can flow into the lower overflow pipe 39. If the handle remains depressed, the water can drain off up to the level of the slots 68. By releasing the handle 55 is closed but the valve bore 49 through the accumulator 50, ao that the water flow can be stopped before reaching the full incremental drain when a sufficient amount of water for flushing has flown. If the handle 55 remains pressed, however, only enough water flows off until the water level in the water tank 10 has dropped to the level of the slots 68. Complete emptying is achieved by removing the

7600907 05/20/76 "" "

Handle 55 is pulled and thus both the upper part control member 35 as well as the lower partial control member 36 together with the closure 41 is lifted from the floor outlet 11. In In this position, the water in the water tank flows through the drainage slot 57 in the bell housing 56 and the floor outlet 11 from. In this case, too, the aforementioned occurs again Schwiiumeffekt of the closure body 41, so that the handle 55 can be released again immediately after pulling, without the closure body before the entire amount of water in its closed position falls back. In this case, there is only one to trigger full and partial emptying Release link necessary. The two emptying methods are selected by either pulling or pressing the release element. The amount of partial emptying can even be controlled as required by the length of time the button is pressed Release link.

As already mentioned, only a few embodiments of the invention are shown in the drawing and this is in no way limited to it. Many other embodiments of the invention are possible, e.g. Combination of the three solution principles. By correspondingly multiplying the components, different subsets can also be created can optionally be emptied.
