Description

TECHNICAL AREA

The present invention relates to a siphon according to the preamble of claim 1.

STATE OF THE ART

From the prior art siphons are known as odor traps. For example, is from the EP 1 447 486 a siphon has become known, which can be mounted in particular below a washstand or a rinsing trough. A disadvantage of the siphon according to EP 1 447 486 is that in a siphon cleaning the housing part must be removed and lying in the siphon water from the housing can escape uncontrollably. The siphon can not be cleaned without the help of a catch basin.

The EP 2 256 261 discloses a siphon having the same disadvantages as the above.

PRESENTATION OF THE INVENTION

Based on this prior art, the invention has for its object to provide a siphon, which overcomes the disadvantages of the above-mentioned prior art. In particular, it is an object that an uncontrolled water leakage in the case of cleaning can be largely avoided.

A siphon arrangement comprises a housing with an inlet connection, an outlet connection and a siphon receptacle arranged between inlet connection and outlet connection, and a siphon element arranged in the siphon receiver with a siphon section and an inlet facing the inlet connection and one for Outlet outlet leading. Water is routable from inlet port to inlet to siphon section and from outlet to outlet port. At the inlet nozzle can be a drain line of a sanitary fitting, such as a washstand or a sink connect, and at the outlet can be connected to a sewer. The siphon is movable in the housing from a use position to a maintenance position, in particular pivotally mounted and is removable from the maintenance position of the housing, in particular pulled out. The siphon is designed such that during the movement of the siphon, the water lying in the siphon at least partially flows to the outlet and that any residual water in the siphon can not escape from the siphon when removing the siphon.

The described design of the siphon element has the advantage that the water in the siphon section can be controlled to flow out of the siphon section at least partially or completely via the outlet connection. This prevents the water from escaping uncontrollably during maintenance work, which typically leads to water damage or major cleaning work.

Preferably, a wall substantially completely surrounds the siphon section except for entry and exit. In other words, the siphon section is formed as a closed channel on the other side.

This design has the advantage that the siphon can act as a kind of vessel. This means that the residual water in the siphon can not escape from the siphon section when the siphon element is removed.

Particularly preferably, the siphon is pivotable by an angle of at most 90 °. Depending on the design of the siphon element, the angle may also be less than 90 °, which has the advantage that not all elements lying in the siphon section, such as a piece of jewelry, are emptied out of the siphon section during the movement of the siphon element.

Preferably, the entry in the use position is substantially higher or higher the same height as the exit. The siphon section extends as seen from the inlet in the direction of gravity down and then back up to the exit.

In addition, the arrangement of inlet and outlet at the same height has the advantage that stagnant water in the siphon is always only in the area which is surrounded by the wall, which is advantageous for the stress of the seals.

Preferably, the outlet is moved against the outlet nozzle during the movement into the maintenance position, the outlet then being lower than the inlet. The water lying in the siphon section can then emerge completely or at least partially through the outlet from the siphon section and flows out via the outlet connection.

Preferably, the siphon section is provided by a partition wall projecting into the siphon section, wherein the partition wall preferably extends between inlet and outlet and provides a passage in the lower area. The lower area is located opposite the entrance or exit. The passage is preferably at the lowest point of the siphon section.

Preferably, the Siphonaufnahme on a cylindrical bearing wall for the storage of the siphon element. The bearing wall is pierced by the inlet connection with the inlet connection. The inlet nozzle thus breaks through the bearing wall and opens into the siphon receptacle. Next, the bearing wall to the outlet is seen through broken with the outlet. The outlet connection closes so the bearing wall.

The bearing wall preferably defines an access opening, via which the siphon element can be inserted into the siphon receptacle.

Preferably, at least one seal extends completely around the inlet, which seal cooperates with said bearing wall and extends completely around the mouth of the inlet nozzle.

The cylindrical bearing wall preferably has at least one completely circumferential wall section and the siphon element has an outer wall with at least one completely circumferential wall section, wherein at least one completely circumferential sealing element is arranged between the two wall sections. Thus, the gap between the wall portion and the bearing wall is sealed with the sealing element.

Particularly preferably, a circumferential wall section in the vicinity of the access opening is arranged from the outside into the bearing section. That is, in terms of access, that from this no water can escape.

Particularly preferably, two spaced apart circumferential sealing elements are arranged, wherein between the sealing elements of the inlet and the outlet are. The sealing elements surround the corresponding wall section such that the inlet or the outlet lies between the two sealing elements.

Preferably, parts of the gasket surrounding the inlet are provided by parts of the sealing element. Thus, a simple sealing structure can be created using the same seal.

Preferably, the outlet nozzle is arranged relative to the inlet nozzle such that water flows when the siphon element is not inserted from the inlet nozzle into the outlet. This is advantageous if water enters the siphon arrangement via the inlet when the siphon element is not used. This water will then flow through the siphon assembly and leave it through the outlet, so that water damage can be largely prevented.

Preferably, the outlet port is arranged such that the outlet of the Siphonabschnittes opens at each position of the siphon in the outlet. This means that the outlet port has an extension which is such that the outlet always opens into the outlet port regardless of the position of the siphon element. The outlet nozzle thus has a larger cross-section than the outlet, wherein the outlet is relatively in the region of this cross-section or in the region of the Outlet nozzle can move.

Preferably, the siphon is mounted via a bayonet lock or self-locking in the housing.

The bayonet closure is preferably designed such that the siphon element can be used exclusively in the correct position in the housing.

Preferably, the siphon has an accessible from outside the housing actuator. The actuating element is preferably designed such that it can be easily grasped by hand without the aid of a tool.

Further embodiments are given in the dependent claims.

The siphon arrangement 1 comprises a housing 2 with an inlet connection 3, an outlet connection 4 and a siphon receptacle 5 arranged between inlet connection 3 and outlet connection 4. Furthermore, the siphon arrangement 1 comprises a siphon element 6 arranged or mounted in the siphon receiver 5 with a siphon section 7 and a siphon section 7 Inlet 3 facing the inlet 8 and a leading outlet 9 to the outlet 9. The siphon section 7 acts as an odor trap. Water is passed from the inlet port 3 via the inlet 8 in the siphon section 7, then passes through the siphon section 7 and then via the outlet 9 to the outlet port 4 from the siphon section 7 wegführbar. The water flows through the siphon section 7.

The siphon 6 is in the Siphonaufnahme 5 in the housing 2 of a use position, as shown in the FIG. 1 is shown, movably mounted in a maintenance position. In the embodiment shown, the siphon element 6 can be pivoted about a pivot axis S. The pivot angle can be up to 90 °. From the maintenance position, the siphon element 6 can be removed from the housing 2. In the embodiment shown, it is pulled out of the siphon receptacle 5 along the pivot axis S. In the FIG. 2 the remote siphon element 6 is shown.

From the sectional view of FIG. 3 can be well recognized as the water is guided from the inlet port 3 via the inlet 8 in the siphon section 7 and then can flow from the outlet 9 to the outlet 4. In the embodiment shown, the outlet 9 is adjoined by an outlet piece 27, which opens into the outlet nozzle 4. The drainage piece 27 is part of the siphon element 6.

In the FIGS. 5 to 7 It is shown that the siphon element 6 is formed such that during a movement of the siphon element 6, the water lying in the siphon section 7 at least partially flows to the outlet port 4. In the FIG. 5 the water lying in the siphon section 7 is symbolized by a dashed line W. In the FIG. 5 the siphon element 6 is shown in the use position. The siphon section 7 is filled with water up to the line W, which runs through the inlet 8 and the outlet 9. Now is the siphon 6 from the use position in the Maintenance position pivoted so that the water lying in the siphon section 7 can flow through the outlet 9 in the direction of outlet 4. This is in the FIG. 6 symbolized by the arrow P. The water thus flows over the edge with the reference numeral 14, which limits the outlet 9, in the direction of the outlet 4 from. Now, the siphon 6 is rotated even further, such as in the FIG. 7 shown, all water can flow out of the siphon section 7. This has the advantage that no or only the smallest possible amount of residual water is present in the siphon element 6 when the siphon element 6 is removed from the housing 2.

The siphon element 6 is furthermore designed in such a way that any residual water in the siphon section 7 can not flow out of the siphon section 7 when the siphon element 6 is removed. That is, the siphon section 7 is formed as a kind of "cup" wherein the water then remains in this "cup". In the embodiment shown, the siphon section 7 is bounded by a wall 10. The wall 10 surrounds the siphon section 7, apart from the inlet 8 and the outlet 9, substantially complete. Thus, the siphon section 7 is formed by the wall 10 as a closed channel on the other side, whereby the just mentioned "cup" can be provided.

Based on FIG. 3 Now further features of the present embodiment will be explained in more detail.

In the use position, the inlet 8 of the siphon section 7 is substantially at the same height as the outlet 9. The outlet 9 can then be moved in the movement from the use position to the maintenance position against the outlet 4, wherein the outlet 9 then lie lower comes as the entry 8. This is in the FIGS. 6 and 7 shown accordingly.

The siphon section 7 is provided by a partition 11 protruding into the siphon section 7. The partition wall 11 extends in the in FIG. 3 shown embodiment between the inlet 8 and the outlet 9. In the lower part of the partition wall 11, a passage 12 is arranged. This passage 12 provides the actual siphon effect. In other words, it can also be said that the Admission 8 a descending Siphonabschnitt connects to the passage 12 and that the passage of high-rising Siphonabschnitt adjoins the outlet 9, wherein the two Siphonabschnitte are separated by the partition wall 11 from each other.

The Siphonaufnahme 5 has a cylindrical bearing wall 13. In this cylindrical bearing wall 13, the siphon 6 is mounted. The siphon element 6 likewise has a cylindrical outer wall 15 which has at least one completely circumferential wall section 19. The siphon element 6 is in contact with the siphon receptacle 5 via the seals described below.

The bearing wall 13 of the Siphonaufnahme 5 is viewed from the inlet port 3 ago broken through the inlet port 3. That is, the inlet nozzle 3 opens into the Siphonaufnahme 5 through the bearing wall 13. In addition, the bearing wall 13 to the outlet 4 seen through with the outlet port 5 is broken. The outlet 4 so also protrudes through the bearing wall 13 in the siphon 5 a. The water passes through the corresponding openings through the bearing wall 13 therethrough.

The bearing wall 13 defines an access opening 24, via which the siphon element 6 can be inserted into the siphon receptacle 5.

Due to the cylindrical design of the bearing wall 13 and the outer wall 15, the siphon element 6 in the siphon receptacle 5, as described above, can be pivoted.

In the FIG. 4 It is shown that a gasket 16 extends completely around the entrance 8. The seal 16 cooperates with said bearing wall 13 and seals the mouth of the inlet nozzle in the region of the inlet 8 completely. In the embodiment shown, a further seal 17 is also arranged.

Next, the cylindrical bearing wall 13 at least one completely circumferential wall portion 18 and the outer wall 15 of the siphon element 6 also has a completely circumferential wall portion 19.

In the embodiment shown, a separate seal 21 is arranged, which lies between the access opening 24 and the inlet connection 3 or in the outlet connection 4. The seal 20 is mounted in a recess 25 in the housing in the region of the bearing wall 13.

In addition, further sealing elements 21 are arranged in the region of the outer wall 15 of the siphon element. In the embodiment shown, two sealing elements 21 are provided, which are arranged such that the inlet 8 or the outlet 9 is arranged between these two circumferential sealing elements 21. These sealing elements 21 work together with the wall portion 18 of the bearing wall 13.

By the sealing element 20 ensures that no water between the separation point between the siphon 6 and the Siphonaufnahme 5 can escape. The sealing elements 21 and the two seals 16, 17 ensure that no water can get into the intermediate region between the siphon element 6 and the siphon receptacle 5.

Of the FIG. 3 as well as from the FIGS. 5 to 7 can be well recognized that the outlet 4 is arranged relative to the inlet port 3 such that water flows when the siphon element 6 is not inserted from the inlet port 3 into the outlet 4. The outlet port 4 in this case has such a large cross-section that, seen in the direction of the vertical, extends below the inlet port 3. Furthermore, the outlet 4 is arranged such that the outlet 9 of the siphon element opens into the outlet 4 at each position of the siphon.

The siphon element 6 is mounted in the housing 2 via a bayonet lock 22. The bayonet closure 2 is arranged such that it lies outside the water-carrying parts. The bayonet lock 22 has two clamping tabs 26 in the embodiment shown. One of the two clamping straps is designed differently than the other of the two clamping straps, so as to ensure that the siphon element 6 can be used exclusively in the correct position in the housing 2.
