A hook, extended radially from the fulcrum, is formed at another part of the arm. An independent claim is also included for a flushing cistern.

Description

The The invention relates to dual-volume drain valve with a housing, in a valve body with a float at its lower end by means of a full flush pull element height adjustable is mobile. An over a partial flushing element actuatable additional element is with the valve body over a reversible coupling element for carrying out a partial flush can be coupled, around the valve body after triggering the partial rinse prematurely in a closed position bring to. The coupling element comprises one with the respective one Counterpart lockable latch.

Often point known drain valves in the housing also has a closable bypass opening in a float chamber receiving the float.

such Drain valves are in a cistern arranged and it can by operation the Vollspülzugelements over a Vollspültaste On a fitting, on the one hand, the full flush volume of up to 9 liters by lifting the valve body rinsed become. To carry out the conditioner the valve body is over the Vollspülzugelement lifted off a valve seat and the float lowers with sinking rinse water level in the cistern until the valve body the drain or the valve seat closes again and thus the closed position occupies.

to Realization of a partial flush of about 3 liters see known drain valves often as additional weight trained additional element ago, which is guided longitudinally displaceable on the valve body and at the partial flush over the Coupling device with the valve body by pressing the Teilspülzugelements can be coupled. The additional weight acts as additional Weight against the buoyancy of the float and thus pushes the valve body faster a corresponding valve seat. The additional weight is preferably over a Teilspültaste operable on the valve, so that the user can clearly distinguish between a full flush and a partial flush can differentiate.

The Tensile elements can For example, include separate pivoting lever, the over Outside operable keys can be operated are. When pressed the keys grip the tension elements on the valve body or on the additional weight to either the valve body alone (full flush) or to raise the additional weight coupled with the valve body (partial flushing). In the partial flush the valve body is over a Coupling element taken with the additional weight. When letting go The "Partial flushing quantity" button loads the additional weight on the valve body and forces it in the manner described before the complete emptying of the cistern prematurely on the valve seat of the drain valve.

Besides the invention relates to a flushing device, with the optional triggering a full and partial flush a valve body a drain valve is to raise.

drain valves and flushing devices this type are known and allow a considerable saving in the amount of flushing water.

A generic drain valve of the type described is for example from the EP 0 722 020 known.

at the known drain valves, the valve body in the opening of the Partition wall of the housing slidably guided. The partition thus separates within the housing the Schwimmerkam mer Pick up the float from above the float chamber the housing trained reservoir. The between the outer surface of the valve body and the opening formed in the partition ring gap allows a controlled Flow away of the rinse water contained in the reservoir, after the water level has been lowered below the reservoir. The annular gap seals the space between the valve body and the opening conditionally and prevents early Lowering the float within the float chamber. Only when the rinse water has passed completely through the annular gap from the reservoir passes Air in the float chamber and causes an immediate closing of the valve. This is justified by that from the reservoir through the annular gap in the float chamber inflowing dishwater prevents air from entering the float chamber and thus by further Lowering the flush volume a vacuum is maintained in the float chamber, even if the rinse water level outside of the housing lower than the height the partition sinks. Only when the rinse water from the reservoir completely through the annular gap has run into the float chamber, this is Negative pressure canceled and the valve thus closes immediately.

In the open position, air can also flow through the formed in the outer surface of the float chamber of the housing bypass opening in the float chamber as soon as the flushing water level has been lowered to the height of the bypass opening and the closing operation (lowering the float) is initiated. By appropriate arrangement of the closable bypass opening thus premature closing can be realized even without complete emptying of the reservoir and thus the Vollspülmenge be regulated via the bypass opening. This bypass opening for regulation the Vollspülmenge is usually at a level of 6 liters flushing.

Known Drain valves for realizing a dual flush are relatively structural in nature complicated and he requires a certain amount of space, e.g. for the additional weight. The variety of moving parts is also particularly with many years of use error-prone, e.g. by abrasion or calcification.

outgoing From this prior art, the invention is based on the object to avoid these disadvantages at least partially and a drain valve to provide for the realization of a dual flush, which has a particularly simple and space-saving design and is also very durable.

The inventive task is solved by that the coupling element against a counter element to achieve a latching position fitting spring element and a against the spring element having active weight element.

The Counterelement can either the valve body or the additional element be. Preferably, on the respective counter element a locking edge, flange, Wreath or the like provided against the spring element at closed valve body issue. Preferably, the valve body has an outside molded on wreath.

By the training of the invention will the mechanical structure of the coupling device significantly simplified and thus their susceptibility to errors decisively improved.

The Additional element can either as additional weight or closing element for one Subset bypass opening be formed in an extension section at the level of Teilspülmenge in the float chamber is arranged and submitted in parallel Application of the applicant is described.

At the Actuate the Teilspülzugelementes is the reversible coupling device with a corresponding counter element Saved to the partial rinse initiate. At the full flush however, only the valve body raised without the closing element, so that the additional element remains in the lower rest position.

By the compact design is the proposed waste set particularly for the Use in cramped and thin Cisterns suitable. Furthermore, the inventive waste set offers a very good quantity accuracy and shortages are almost completely excluded. She needs also low conversion costs.

The Spring element is at least when the valve is closed in the closed position against a stop and is thus filled cistern (filling water level above the Latch) in the open (not latched) rest position pressed.

The Spring element may for example comprise a leaf spring which extends radially from a pivot point for attachment of the latch. Alternatively, it is also conceivable that the spring means formed as a spiral spring are, which are formed around the preferably designed as a pivot pin is arranged. This coil spring is against a first end the one element (additional element or valve body) and with a second End against the corresponding counter element.

Preferably acts formed on the latch and upwardly open container filled with rinse water as a weight, which the pawl above the rinse water in the locked position presses to couple the elements.

To the Simplify the installation of the drain valve in confined spaces with Cisterns with greater Height and / or shallow depth, the valve body can be formed separable and / or bendable. The connection of the two Parts of the valve body can e.g. above an elastic connecting element or by means of a rotary joint take place, which e.g. formed on the one part of the valve body Pins and these on the other part of the valve body in installation position embracing Eyes includes. Other suitable embodiments for pivotable connec tion are within the scope of the invention.

The figures show a cistern, not shown 86 usable drain valve 2 , To operate the drain valve is in the upper part of the cistern 86 arranged a known actuator. This has, for example, two separate tension elements, which are preferably mounted independently of each other pivotally mounted on a web of the cistern. These tension elements have at one end in each case a full-quantity and a partial-quantity button, which are accessible from the outside and can be actuated by hand to trigger a flushing.

The Vollspülzugelement engages with the opposite end of a Vollmengentaste in a Ventilkörperöse 4 a valve body 6 a, which is designed here as an overflow pipe. Pressing the full volume key will turn the valve body 6 raised.

One as a slider 10 trained additional element is height adjustable on the valve body 6 attached.

To lift the slider 10 and the valve body 14 The tension elements can be actuated by means of buttons, as usual with cisterns. Also conceivable are other actuators with which either the slide 10 or the valve body 14 can be raised.

When lifting the valve body 6 becomes one at the lower end of the valve body 6 arranged valve disc 12 from a valve seat 13 the drain valve 2 raised. In the cistern 2 containing rinse water can then through the window of the housing 14 through the drain pipe into a toilet bowl, not shown flow. The raised valve body 6 is by a float 18 kept floating in a conventional manner until the cistern is substantially completely emptied. By pressing the full volume key, a full flush is thus triggered. The slider 10 is uninvolved in this case.

To trigger a partial flush the partial quantity key is actuated and thus the slide 10 with the valve body 6 raised.

The housing 14 includes inside a horizontally extending partition 22 which the housing 14 in a lower float chamber 24 for picking up the shimmer 18 and an upper reservoir 26 divides. The reservoir 26 is up to the cistern open. The partition 22 has a central passage opening, in which the valve body 6 slidably guided.

The coupling device according to the invention for the reversible coupling of the slider 10 with the valve body 6 is designed as a spring latch, which in its entirety by the reference numeral 28 is provided. The spring latch 28 is rotatable at a fulcrum on a radially outside of the valve body 6 outstanding cones 30 clipped.

The spring latch 28 has in the present embodiment, a radially extending from this pivot arm 32 on, at the free end of an open-topping pot body 34 is integrally formed. This pot body 34 When the rinse water level drops, it absorbs rinsing water and thus forms a weight body. Integrally molded to the spring latch 28 extending radially from the pivot point and approximately transverse to the imaginary longitudinal axis of the arm 32 is a latching hook 36 formed with an inwardly offset undercut. The geometry of this undercut corresponds negatively to the geometry of a corresponding laterally on the slide over 10 molded detent 38 , Slightly offset downwards, parallel to the axial direction of the pin 30 extending is at the back of the spring latch 28 a spring arm 40 formed, which is a radially outwardly extending guide slope 42 on the valve body 6 engages in installation position. This spring arm 40 creates a force on the spring latch 28 that causes the spring latch to release without the counteracting weight force of the water-filled pot body 34 held in the non-latching position, as in the 1 to 4 is shown.

At the bottom of the slider 10 is a substantially cylindrical valve plate 44 molded, which is offset parallel to the longitudinal axis of the valve body 6 extends downwards. This valve plate 44 sits in the 1 to 8th on one in the 9 to 11 illustrated partial quantity bypass opening 46 in the upper horizontal wall 48 an extension section 50 on, which is connected on the inside with the float chamber and chimney-like one-sided next to the reservoir 26 extends to a height corresponding to the desired Teilspülmenge. Preferably, this Teilspülmenge is arranged in the installed position in the cistern of a height corresponding to a Teilspülmenge of 3 liters.

The 5 to 8th show the drain valve 2 at the full flush. The in the valve body eye 4 engaging Vollspülzugelement has the valve body 6 lifted from the closed position, leaving the valve disk 12 the mouth of the drain neck 16 releases. Approximately 9 Liters rinse water now flow through the side openings of the valve seat 13 in the outlet pipe 16 , Because the spring latch 28 when lifting the valve body 6 is in the rinse water, the weight of the water filled pot body acts 34 not against the spring arm 40 generated spring force, which in the closed position against the guide slope 42 of the valve body 6 is applied. That's why the latch hook is 36 the spring latch 28 not with the catch 38 of the slider 10 locked. As a result, the slider becomes 10 when flushing, not when lifting the valve body 6 with raised.

The 9 to 12 show the drain valve 2 at the partial rinse. This is an arm 52 pulled up by the Teilspülzugelement, which at the upper end of a parallel offset to the longitudinal axis of the valve body 6 extends. This arm 52 is on the upper side in one piece to the slider 10 formed. When lifting, the upper edge of the slider beats 10 against a wreath 54 on, the radially outwardly circumferentially on the cylindrical valve body 6 is formed. This wreath 54 forms a stop, which when lifting the slider 10 the valve body 6 entraining. In the raised position, the weight of the now located outside the rinse water and filled with rinse water pot body acts 34 and presses the latching hook 36 the spring latch 28 in the closed position for locking with the corresponding locking lug 38 , The slider 10 is thus with the valve body 6 coupled and thus decreases even when you release the Teilspültaste controlled with the valve body 6 from.

Lifting the slider will cause the partial flow bypass opening 46 Approved. When the drain valve is open, the rinse water flows in the manner described above through the drain pipe 16 until this level of partial flow bypass opening 46 has dropped. Then air passes through the subset bypass port 46 in the float chamber 24 one, the negative pressure in the float chamber 24 is interrupted and the valve body 6 sinks with his valve plate 12 in the in the 1 to 4 shown closed position on the sealing seat.

Laterally at a corner of the extension section 50 is a shutter 76 in one at the extension portion 50 trained dovetail guide height adjustable used. This slidably mounted in the dovetail guide slide 76 selectively covers full-volume bypass ports at various fill levels in the priming section 50 from. Thus, this shutter can 76 can be used to selectively release or close the full volume bypass ports. So you can easily set different Vollspülmengen, from the drain valve 4 closes.

All embodiments of the drain set can be designed to be bendable for installation in thin cisterns and confined spaces. For this purpose, the valve body 6 separable and consists of a lower valve part 78 and a latched on this upper valve member 80 , The upper valve part 80 forms an extension of the lower valve part 78 and may be replaced by one of a different length to accommodate the height of the cistern. The upper valve part 78 is with two molded notches on the lower valve part 78 rotatable and releasable latched.

The drain valve according to the invention 2 can have a back-up mounting tab 82 in a cistern 86 to be assembled. This mounting tab 82 engages in the installation position on the cistern 86 rotatably mounted holder 88 , This holder 88 is for fixing the drain valve 2 in the cistern 86 in the in 25 rotated mounting position shown, so that the mounting bracket 82 the holder 98 engages and the drain valve 2 thus stationary in the cistern 86 is fixed.

The according to the invention, as Federklinke trained coupling device is of course also usable with other and known additional elements, for example with pot-like additional weights.

The subject matter of the present invention results not only from the subject matter of the individual claims, but also from the combination the individual claims among themselves. All information and features disclosed in the documents - including the abstract - in particular the spatial design shown in the drawings are claimed as essential to the invention, as far as they are new individually or in combination with respect to the prior art.
