DESCRIPTION

Siphon accessible to a plunger by an inlet opening The invention relates to a siphon according to the preamble of claim 1.

Such a siphon are known in the prior art, for example, from DE 102006053751. A siphon can, for example, be used for a shower drain. It is important here that the height of the siphon is limited, since the drain of a shower is located on the floor and the thickness of the floor can limit the maximum overall depth.

In addition, it is important to comply with the regulations regarding the siphon water collector having a certain minimum height.

Finally, it is desirable to be able to extract the siphon for cleaning, but also to have access to the outlet pipe to which the siphon is connected. The latter is important if there is a plugging and it is necessary to clean the outlet pipe, for example, with a plunger.

In known siphons, access to the outlet pipe is limited because there is an upright vertical intermediate wall from the bottom. When, for example, it is necessary to insert a plunger into the outlet pipe, it must be inserted between the vertical wall and the housing, after the tubular part is removed. If the objective is the minimum overall depth possible, the space between the housing and the vertical wall is adversely affected.

In addition, it is normal for an outlet pipe of a sump or shower drain to which the siphon is connected to also protrude into the inlet opening. The lower edge of this outlet pipe also determines the accessibility of the outlet opening of the housing.

In addition, it is desirable from an aesthetic point of view to have increasingly narrow and small entry openings. This, however, avoids the possibility of constructing the siphon from separate and removable components.

It is now an objective of the invention to improve access to the outlet pipe, while the total height of the siphon can be minimized.

This objective is achieved according to the invention with a siphon according to claim 1.

When the cap is removed for cleaning purposes, ample space is created through the opening to the outlet pipe behind. This access is no longer limited by the space between the vertical wall and the housing. This opening in the wall now also allows more freedom in the design of the siphon, the vertical wall and the housing.

Here it is possible that the upper edge of the vertical wall is in a position higher than the lower end of the inlet opening or the outlet pipe inserted from a sump or shower drain disposed in the siphon. It is even possible to guide and seal this outlet pipe at an edge that hangs down from the inlet opening, thus creating adjustability.

In an embodiment of the siphon which is not in accordance with the invention, a part of the wall of the tubular part rests against the opening in the intermediate vertical wall.

As the tubular part rests against the opening, a simple construction is obtained, in which the removable tubular part easily seals the opening in the vertical wall.

In another embodiment of the siphon which is not in accordance with the invention, a vertical edge is arranged along the periphery of the opening in the intermediate vertical wall, and the tubular part rests against the vertical edge.

In fact, a tunnel is formed by the vertical edge along the periphery of the opening, this tunnel partially covering the distance between the vertical wall and the tubular part.

In the siphon according to the invention there is arranged an edge that hangs down, around the inlet opening. The tubular part, not according to the invention, can rest against the edge that hangs down, whereby a guide and positioning for the tubular part is formed. Preferably a seal is provided between the tubular part and the edge that hangs down from the inlet opening. This prevents a direct connection between the inlet opening and the outlet pipe, so that unpleasant odors can escape from the siphon through the inlet opening.

In a preferred embodiment of the siphon according to the invention, the opening in the intermediate vertical wall rests substantially on the same line as the outlet opening. Here, for example, a plunger, can be easily introduced into the outlet opening through the inlet opening and the opening in the vertical wall.

In another preferred embodiment of the siphon according to the invention, the inlet opening has an elongated shape, such as

An ellipse or a rectangle.

A siphon that is not in accordance with the invention comprises:

- a housing with at least one lower part, an upper part and a wall extending between the lower and the upper part, where an inlet opening is arranged in the upper part and where the housing further comprises an outlet opening;

-a dividing wall that hangs down from the top and divides the housing into two chambers that are connected to each other near the bottom, through an opening in the dividing wall;

- an outlet pipe that extends through the outlet opening, where the end surface of the outlet pipe extends at least as much as a conduit in the dividing wall, where an opening is directed towards the top of the housing, in the part of it had located in the housing;

-a removable sealing element arranged in at least the outlet pipe in order to seal the conduit.

Since the outlet pipe is inserted into the housing, the housing can have a simple shape. In addition, easy cleaning of the siphon of the invention is ensured through the sealing element of the outlet pipe.

In a preferred embodiment of the siphon, which is not in accordance with the invention, the outlet pipe extends through the duct in the partition wall, and the part of the outlet pipe that extends beyond the wall of the division is sealed by the sealing element.

These and other features of the invention will become clearer from the accompanying drawings.

Figure 1 shows a perspective view of a first embodiment of a siphon that is not in accordance with the invention.

Figure 2 shows a cross-sectional view of the siphon of Figure 1.

Figure 3 shows a cross-sectional view of the siphon of Figure 1 during cleaning.

Figure 4 shows a perspective view with partially cut parts of a second embodiment that is not in accordance with the invention.

Figure 5 shows a cross-sectional view of a third embodiment that is not in accordance with the invention.

Figure 6 shows a cross-sectional view of an embodiment according to the invention.

Figure 7 shows a cross-sectional view of a fourth embodiment that is not in accordance with the invention.

Figure 8 shows a cross-sectional view of a fifth embodiment that is not in accordance with the invention.

Figure 9 shows a sixth embodiment that is not in accordance with the invention.

Figure 10 shows a seventh embodiment according to the invention.

Figures 1 and 2 show a siphon 1 that is not in accordance with the invention. This siphon 1 has a housing with an upper surface 2, a lower surface 3 and a peripheral wall 4 extending between them.

In the peripheral wall 4 there is an opening to which the outlet pipe 5 is connected.

A vertical intermediate wall 6 is arranged on the lower surface 3. In this vertical intermediate wall 6 there is a conduit 7 that is substantially in line with an outlet opening 8 to which the outlet pipe 5 is connected.

Also provided on the upper surface 2 of the siphon 1 is a feed opening 9 in which a removable tubular part 10 is located. This tubular part 10 is supported by a rib 11 arranged along the feed opening 9. The tubular part 10 is further supported against the vertical intermediate wall 6 in the position of the conduit 7. The tubular part 10 seals the conduit here.

In the situation of the siphon which is not according to the invention shown in Figure 2, the siphon normally forms a water collector. The outlet pipe 14 of a sump, such as the sump 13 of a shower, is inserted between the tubular part 10 and the edge that hangs down from the feed opening 9. The distance between the siphon 1 and a sump 13 may vary. It is clearly seen that the bottom edge of the outlet tube 14 is in a position

lower than the upper edge 15 of the vertical intermediate wall 6. This is not possible in a prior art siphon, since such a prior art siphon could no longer be cleaned.

Water W flows through the feed opening 9 towards the tubular part 10. Water enters here in the chamber limited by the vertical intermediate wall 6. Next, the water flows over the edge of the intermediate wall 6 and enters a second chamber limited by the intermediate wall 6 and the peripheral wall 4. Finally, the water W exits through the outlet pipe 5. Because the upper edge 15 is in a position higher than the lower edge of the outlet pipe 14, it is possible to provide a larger water collector when the housing 2, 3, 4 has a certain height.

Figure 3 shows the siphon 1 which is not in accordance with Figure 1, where the tubular part 10 has been removed from the feed opening 9. As the tubular part 10 has been removed, the duct 7 is clearly visible. It is thus possible to introduce, for example, a plunger 12 directly into the outlet pipe 5 through the opening 9 and the duct 7. This considerably facilitates the Cleaning and unblocking.

Figure 4 shows a second embodiment 20 of a siphon that is not in accordance with the invention. This siphon 20 also has a housing 21, where the oval shaped feeding opening 22 is disposed on the upper surface. Inserted in this oval feeding opening 22 is an oval tube part 23 that is disposed on the bottom side with a hole 24.

A vertical intermediate wall 25 that is interrupted by the oval tubular part 23 is also disposed on the bottom surface in the housing 21. In the inserted position of the tubular part 23, the intermediate wall 25 is thus completely sealed, so that a first chamber is formed in which the water W enters from the feed opening 22. Water then flows over the upper edge of the upper intermediate wall 25 and thus enters a second chamber, after which it can be drained through the outlet pipe 26.

Figure 5 finally shows a third embodiment 30 that is not in accordance with the invention. This siphon 30 generally corresponds to siphon 1 of Figure 1. A housing 31 with a feed opening 32 on the upper surface is also provided in siphon 30. Inserted in this feed opening 32 is a tubular part 33 which, like the tubular part 10 of the siphon 1, has a hole 34.

Arranged on the inner surface of the housing 31 is a vertical intermediate wall 35 that is concentrically disposed relative to the tubular part 33. A conduit 36 is arranged in an intermediate wall 35. Connected to this conduit 36 is a horizontal tube part 37 that extends between the conduit 36 and a tubular part 33. The direct connection between the chambers on both sides of the wall 35 is sealed here by the tubular part 33. A peripheral ring 38 is arranged in the tubular part 33 for sealing. An easy access to the outlet pipe 39 is created after the removal of part 33.

Figure 6 shows a variant of embodiment 30 of Figure 5 which is according to the invention. The same parts are designated with the same reference numbers.

In this variant, the tubular part 33 of Figure 5 is omitted. Instead, a plug 65 is disposed in the conduit 36.

Figure 7 shows a fourth embodiment 40 that is not in accordance with the invention.

The siphon 40 has a housing with an upper part 41, a lower part 42, and a peripheral wall 43 extending between them. A feed opening 44 is provided at the top. Arranged on this upper part is a vertical edge 45 where a grid 46 can be placed. The upper side of the grid 46 can be arranged approximately in the same plane as the upper side of, for example, a tiled floor.

Also hanging down from the top 41 is a dividing wall 47 that divides the housing into a first chamber 48 and a second chamber 49. The dividing wall 47 stops just before reaching the bottom 42, so that there is a connection 50 between the first camera 48 and the second camera 49.

An outlet opening 51 is also disposed in the housing that leads to a second chamber 49. Through this outlet opening 51 an outlet pipe 52 protrudes, the end surface 53 of which rests against the dividing wall 47. In this dividing wall there is a conduit that is sealed by a plug 54. When this plug 54 is removed, a direct connection is created between the outlet pipe 52 and the feed opening 44, thus allowing easy cleaning.

The outlet pipe 52 is further provided on the upper side of an opening 55, this opening 55 being directed in the direction of the upper part 41 of the housing.

Water flowing through the feed opening 44 and enters the first chamber 48 of the housing can then flow through the connection 50 to a second chamber 49. Here, the water must move upward to be able to flow and enter the opening 55 of the outlet pipe 52. This generates a siphon action.

Figure 8 shows a variant of the embodiment according to Figure 7. The same parts, therefore, are

designate with the same reference numbers. In this embodiment 60, the outlet pipe 52 is also inserted through the conduit in the dividing wall 47, so that the end surface 53 of the tube is now located in the first chamber 48. The end surface 53 is completely sealed in relation to the first chamber 48. However, a sealing element 61 is placed on the end surface 53, so that easy access to the outlet pipe 52 can be gained in order to clean the siphon 60.

Figure 9 shows a sixth embodiment 70 that is not in accordance with the invention. This embodiment has a housing 71 with a flow inlet opening 72 on the upper side. A stepped peripheral wall 73 hangs down from this flow inlet opening 72. A first chamber 74 is formed by this wall 73 that hangs down.

An outlet pipe 75 is disposed against the housing 71. This outlet pipe 75 has on its upper side a conduit 76 through which the outlet pipe 75 is connected to the first chamber 74.

Water W entering the housing through the flow inlet opening 72 must subsequently flow below the wall 73 that hangs down and then upwards in the first chamber 74 towards the conduit 76 that is above. Water W can then flow through conduit 76 to pipe 75.

The flow inlet opening 72 is sized such that the shower drain 77 can partially protrude into the flow inlet opening 72. The outlet pipe 78 of the shower drain thus protrudes from inside the tube formed by the wall 73 that hangs down. This considerably limits the height of the combination of siphon 70 and shower drain 77.

Figure 10 shows a seventh embodiment 80 that is not in accordance with the invention. This embodiment closely resembles a siphon of the prior art.

The embodiment 80 which is not in accordance with the invention has a housing 81 with an outlet 82 on the bottom side. A funnel-shaped feed opening 83 is disposed on the upper side of the housing 81.

A receptacle 84 is also provided under the funnel-shaped feed opening. This receptacle 84 ensures that the water W entering through the feed opening 83 must first flow upwardly over the upper edge of the receptacle 84 to reach the outlet 82.

An opening with a plug 85 is also provided at the bottom of the receptacle 84. After removal of the plug 85, direct access to the outlet 82 can be achieved through the feed opening 83.

A siphon according to the prior art is removable to allow siphon cleaning. The funnel-shaped feed opening 83 can be integrated with the housing 81.

Of course, it is clear that the siphon according to the invention is suitable for shower sinks, bath sinks, and also for sinks where the overall height is important and accessibility is limited after installation.
