Description

Impulse flush siphon

The invention relates to an impulse flush siphon for dispensing selectable Amount of water, with a chamber open at the bottom, the upper end with a downpipe is connected and which contains a pulse piston which is connected to a shaft via a Handle is connected, and with a ventilation opening arranged at the middle level, which is connected to the path of the draining water in a lockable manner.

Impulse flush siphons are known for toilet cisterns that have one have liftable lifting plate, by its upward movement water in the chamber is pushed up and directed into a downpipe. As a result of the flow of water the downpipe creates a suction in the chamber, through which more water emerges the chamber and out of the cistern surrounding the chamber. The dragging of the water is only stopped when the water level in the cistern has sunk below the lower opening of the chamber so that air enters the chamber. Impulse rinsing siphons of this type cause the corresponding handle to be actuated an almost complete emptying of the water tank. The one given by them The amount of water is therefore always the same. This has the disadvantage of flushing toilets that it is always rinsed with the same amount of water, the largest possible Flush requirement is turned off. Now it is enough to flush away the urine when urinating but a smaller amount of water. To avoid unnecessary water consumption are Impulse rinse siphon known, the two different handles resp.

Have push buttons (DE-OS 24 40 292). Such impulse rinsing phones have e.g. two separate chambers that are at different heights in the Cistern are arranged and each have a separate lifting plate. At the If you lift a lifting plate in the upper chamber, the water runs out of the cistern just down to the bottom of the upper chamber, which is about half of the total Corresponds to the water content of the cistern. When the lifting plate is actuated, the lower Chamber, on the other hand, almost all of the water contained in the cistern runs out. The disadvantage here is that two separate chambers are required, which is an additional Material and manufacturing cost means, and that a flap is also provided must be through which either one chamber or the other chamber is airtight the downpipe is to be connected. The flap is operated by the water pressure.

In other known embodiments, the height is one in the cistern provided single embodiment adjustable. To this end, the Chamber must be height adjustable in the cistern and also is a separate Handle to be operated required to adjust the height of the chamber. at Another embodiment is at the one connecting the chamber with the downpipe Manifold a valve arranged by a float located in the cistern is controlled in such a way that it opens at a medium liquid level and thus interrupts the flow of water through the downpipe. The effect of this swimmer can be switched off so that the shut-off valve does not open at all and the water tank runs empty.

Finally, an impulse flush siphon with a selectable amount of water is known (DE-OS 26 11 295), in which the downpipe has a valve with a ventilation opening is connected, which is arranged in a middle height of the water tank. at When the valve is open, the flow of water through the filling tube is cut off as soon as the ventilation opening is opened is released from the water. When the valve is closed, however, the cistern runs empty until the water level reaches the bottom of the chamber. To select the one you want Flush volume, the valve must be set in one position or the other.

The well-known impulse rinse siphons for dispensing selectable amounts of water have the disadvantage that either a separate actuator is required, which is on full or partial emptying must be switched, or that two separately the handles to be operated are arranged at different points in the cistern, whereas in the second case an additional chamber with a separate lifting plate is required will.

The invention is based on the object of a pulse flush siphon To create the type mentioned at the beginning, which gets by with a single chamber and none separately arranged operating lever for setting the required amount of water needed.

To solve this problem is according to a first variant of the invention provided that the ventilation opening on a pipe socket leading out of the chamber is arranged through which the shaft passes, and that the shut-off device for Blocking off the path through the vent opening into the chamber at a coaxially too the shaft extending tube is attached to which a second handle is attached is.

When you operate the second handle, the path through the ventilation opening automatically adjusted or closed by the shut-off element by the shut-off element is brought into the closed position.

When the water level reaches the vent, the chamber aerated and the flow of water is interrupted The inventive Impulse flush siphon enables one-handed operation by actuating a single one Handle and gets by with a single chamber. The user only needs pulling or twisting the handle in question, both Handles surround each other coaxially. Preferably the lower handle is larger formed, which suggests that the larger amount of water through this handle is released.

In an advantageous embodiment of the invention, the shut-off device is an edge protruding from the pipe, which is located on the pipe socket when the pipe is lifted the chamber and closes it. The interruption of the way from the ventilation opening In this case, the chamber does not take place directly at the ventilation opening, but rather at the point where the pipe socket ends inside the chamber.

Due to the flow acting against the shut-off element from below the shut-off element is held in the closed position so that the cistern runs empty. Then the impulse piston or lifting plate and the shut-off device both sink back to the rest position. If, on the other hand, the first handle is pulled the shut-off element remains in its open position. Through the downpipe caused water flow, water runs from the cistern into the chamber and from there into the downpipe.

The second handle is expediently tight in the rest position arranged under the first handle, and he takes it with him when pulling it up.

To reduce the amount of water that runs out when you pull the first handle, to be able to change, is in an advantageous development of the invention, the ventilation opening a slot with a vertical component through a height-adjustable plug is partially closable. The plug covers the top of the slot and indicates the level of the effective edge of the ventilation opening.

When the water level in the cistern has reached this level, will the water dispensing interrupted. The slot can be on the wall of the pipe socket diagonally run and are partially blocked by a rotary valve, whereby the the upper area of the diagonal slot can be increasingly closed or released. Stepless adjustment of the level is thus possible. The rotary valve can also be taken by turning the second handle. In one embodiment the rotary valve is the sole shut-off device, lifting the handle is involved not provided. The rotary valve can also be turned using the handle.

According to a second variant of the invention, that specified above The object is achieved in that the chamber is designed as a pulse piston, which the Downpipe surrounds that the ventilation opening is arranged on the wall of the chamber, and that the chamber and the shut-off device for blocking the path through the ventilation opening are rotatable relative to each other.

In the case of such a pulse flush siphon, the one acting as a pulse piston Chamber depressed, which reduces the chamber volume and water out the chamber is pushed into the downpipe. As a result of the resulting suction, it becomes water pulled out of the cistern into the downpipe. The suction is ended when the ventilation opening provided in the side wall of the chamber of the Falling water level in the water tank is released and air into the chamber got.

In the second variant, the shut-off element is preferably on the Fastened downpipe and mounted the chamber rotatably. The chamber over the (only) The handle can be depressed by turning the handle as well twisted, whereby the ventilation opening is more or less released or is blocked.

In this way, the desired flush volume can be achieved with a single handle (Amount of water) is set and triggered by pressing down the same handle will. The simple construction is of particular advantage. Because the shut-off device can turn made in one piece with the downpipe, except for the shut-off device only the chamber is required as an additional part.

The chamber, which acts as a pulse piston, can also have a float have and, depending on their altitude, a valve for admitting water steer into the water tank. The chamber thus takes on the further function of the usually separately provided float for switching off the inlet valve when the upper water level in the water tank is reached.

The shut-off element expediently has an inclined shut-off edge on, which depends on the position of the shut-off device and chamber relative to each other the ventilation opening is limited or at different heights.

the ventilation opening is completely blocked. This way is a stepless one Regulation of the amount of water to be dispensed by turning the chamber appropriately possible.

Some exemplary embodiments are described below with reference to the figures the invention explained in more detail.

They show: FIG. 1 a longitudinal section through a cistern and a first embodiment of the impulse siphon located therein in the first variant, Figure 2 shows a modified embodiment of the impulse flush siphon according to Figure 1 and Figure 3 shows an embodiment of the second variant of the invention.

The cistern 10 according to Figure 1 has in addition to the impulse siphon 11, the is arranged in its interior, a water inlet, which is controlled by a float Shut-off valve is provided. This inlet is not shown in the drawing.

The siphon 11 rests on the bottom 12 of the cistern 10, the one below has open chamber 13, the upper outlet 14 via a manifold 15 with a vertical downpipe 16 is connected through an opening in the bottom wall 12 of the container protrudes. Between the openings 17 at the lower edge of the chamber 13 has the Impulsspülsiphon feet 18, with which it is on the bottom wall 12 of the Cistern rests. Inside the chamber 13 is a lifting plate 19, which is about a vertical shaft 20 with a handle arranged above the cistern 21 is connected. The shaft 20 extends through a pipe socket 22, the the inclined upper wall of the chamber 13 is formed. The pipe socket 22 has a narrowed upper portion 23, which is also from the opening of the top wall of the cistern 10 protrudes. On top of the section 23 rests on one a sealing and shock absorbing ring 24 of the plate-shaped handle 25, through which the Shank 20 passes through it coaxially.

The handle 25 is connected to a tube 26 that supports the shaft 20 surrounds coaxially and also runs through the pipe socket 22. The lower End 27 of tube 26 is widened and has a radially protruding lower edge 28, which in the raised state of the tube 26 sealingly against the lower Edge 29 of the pipe socket 22 sets.

The pipe socket 22 is located at an intermediate level in the cistern the ventilation opening 30. In the space behind this ventilation opening 30 protrudes from at the top a vertical cylinder wall 31, which is an extension of section 23 represents.

The operation of the device is as follows: Is on the handle 21 pulled while the handle 25 remains in its rest position, then is the lifting plate 19 is raised, whereupon water flows through the elbow 15 into the downpipe 16 flows. As a result of the suction or the air pressure acting on the open water surface water flows from the cistern 10 through the openings 17 into the chamber 13 and from there into the downpipe 16. This process is ended when the water level is up the intermediate level 34 has fallen, with part of the ventilation opening 30 being released will. Air now passes through the ventilation opening 30 into the interior of the pipe socket 22. Since the flow resistance of the path through the openings 17 and past the Lifting plate (impulse piston) 19 is greater than the flow resistance through the pipe socket 22, after the ventilation opening 30 has become free, the water level in the pipe socket falls 22 immediately down to the level of the lower edge 29, so that air into the chamber 22 arrives.

After reaching the intermediate level 34, therefore, the further water is dispensed interrupted.

If the lower handle 25 is pulled, then it picks up the him resting upper handle 21 with. The pipe 26 is lifted into its upper position, in which the edge 28 presses against the lower end 29 of the pipe socket 22. When lifting of the lifting plate 19 is therefore the lower opening of the pipe socket 22 from the edge 28 or the pipe part 27 closed. This makes the way through the ventilation opening 30th blocked through into the chamber 13, so that a premature termination of the dispensing process can not take place and the water runs out to the minimum level 35.

Only then do the shaft 20 and the tube 26 sink back into the rest position back, which frees the ventilation path again.

To adjust the level at which the path through the ventilation opening 30 is released when the shut-off element 28 is lowered, a plug 36 is used, which is between the wall 31 and the outer wall of the pipe socket 22 in the area of the ventilation opening 30 can be moved into it.

In the embodiment of Figure 2 are those parts that have the same function as in the embodiment of Figure 1 with the same Provided with reference numerals.

The pipe socket 32 is continuously cylindrical in FIG and extends from the wall of the chamber 13 to the top wall of the cistern 10. The rod 20 runs through the center of the pipe socket 32, which is at its upper one The end of the handle 21 carries. The rod 20 is surrounded by a cylinder 37, the The outer wall rests tightly against the inner wall of the pipe socket 32. The cylinder 37 protrudes also out of the top wall of the cistern 10, and is at its upper The end is designed as a rotary knob 33. A pointer 38 protrudes from the rotary knob 33, which can be pivoted along a fixed scale 39.

The ventilation opening 30 is a vertical slot in the wall of the Pipe socket 32. The slot 30 can be of the acting as a shut-off cylinder 37 are locked. The hollow cylinder 37 has a helical shape Slit 40, the various zones of which in the area of the ventilation opening 30 can be rotated. There are openings in the bottom wall of the cylinder 37 41. The ventilation opening 30 can be blocked by turning the rotary knob 33. To regulate the mean water level 34, the cylinder 37 is rotated, see above that the height of the helical slot 40 and the slot-shaped ventilation opening formed window changes.

The second variant of the invention is shown in FIG. That Downpipe 11 that passes through the bottom wall 12 of the cistern 10, and out consists of a freely upwardly tapering piece of pipe is centered in a bell-shaped Chamber 45 arranged, which also has the function of the pulse piston. Which widening lower edge of the chamber 45 is guided in a cylinder 46 of the bottom wall 12 rises, and has openings 47 in its lower region.

At the top of the chamber 45 is a socket 47 into which the stem 48 of a handle 49 protrudes. The Iland handle 49 is rotatably with the socket 47 and thus also connected to the chamber 45. Will be on the handle 49 rotated, then the chamber 45 rotates with it. The rotary position can be controlled by a from the handle 48 projecting pointer 50 can be read on a scale.

The shut-off element 51 consists of a ring 52 with an arm star 53 is firmly attached to the downpipe 11. The shut-off element 51 has a lower one Barrier edge 54, the height of which changes helically.

The ventilation opening 55 is a vertical slot in the side wall of the chamber 45. In the illustrated rotational position of the chamber 45, the ventilation opening 55 closed by the shut-off device 51. The chamber 45 is opened by turning the handle 49 rotated, then the shut-off edge 54 reaches the area of the ventilation opening 55, so that the ventilation opening is partially blocked by the shut-off element 51 and is partially released.

To operate the water rinse, the handle 49 is depressed. As a result, the chamber 45, which acts as a pulse piston, is depressed, so that some of the water it contains is pressed into the upper end of the downpipe 11 will. As a result of the resulting suction, more water is drawn from the interior the chamber 45 is drawn into the downpipe 11 and flows through into the chamber 45 the openings 47 water from the cistern 10 after.

When the chamber 45 is pressed down, the upper end of the shut-off element acts 51 as a stop for a shoulder 56 which is provided in the interior of the chamber 45. This stop prevents the chamber 45 from being pressed down to the bottom 12 can be, so that it is ensured that the openings 47 are not from the lower Edge of the chamber 45 are blocked.

A float 57 is also attached to the chamber 45, which subsequently A flushing process causes the chamber 45 to be raised again to the upper position will. The function of this float or the upward movement of the chamber 45 can can be used to switch off the float valve 58, which is used to fill the washing container 10 through a pipe 59 ending just above the bottom 12, water into the washing compartment directs. The control of the valve 58 takes place via a rod 60, which is at the top End of the chamber 45, e.g. at the socket 47, engages and with the control part of the valve 58 is connected.

The second variant shown in Figure 3 is characterized by a particularly simple construction. Another advantage is that on the handle 49 by turning the desired amount of water that comes out of the downpipe during the flushing process should emerge, set and at the same time by depressing the flushing process can be triggered.
