Description

DESCRIPTION

[0001] The invention relates to a stench trap. Such a stench trap is known from DE 202004013128 U. When such a stench trap is mounted against the wall in order to save space under a washbasin or sink, the problem can occur that the height difference between the outlet pipe in the wall and the connecting pipe from the washbasin or sink does not correspond to the height difference between the inlet opening and outlet opening of the stench trap. In such a case it is then necessary to arrange adapters in the connecting pipe. It may be the case here that the difference in height is too small for a usual adapter.

[0002] It is further the case that sinks and washbasins are being hung increasingly higher. This is the result of the increase in the average height of people. It is also usual to arrange the washbasin or sink higher in order to make a washbasin or sink wheelchair-accessible. Particularly as a result of renovation this means that the outlet pipe opening in the wall comes to lie at an increasingly lower position relative to the washbasin or sink.

[0003] It is now an object of the invention to provide a stench trap which can be mounted against the wall and wherein the fewest possible modifications to conduits and coupling pieces are necessary.

[0004] This object is achieved according to the invention with a stench trap according to claim 1 and according to claim 2. It is possible according to the invention using the tubular insertion part to compensate the height difference between the inlet pipe, from for instance a washbasin or sink, and the outlet pipe in the wall. A stench trap can thus be arranged on the wall whereby the least possible space is taken up under the washbasin or sink, this in turn increasing the storage space of a cabinet to be placed under the washbasin or sink. It is hereby possible to arrange drawers under the washbasin or sink, or a washbasin can be made more readily wheelchair-accessible.

[0005] In the prior art stench trap the free end of the tubular insertion part debouches to the front, while the outlet opening debouches to the rear. When the outlet pipe in the wall does not lie in line with the outlet opening of the washbasin or sink, it is then necessary to arrange bends in the pipe from the outlet opening of the washbasin or sink to the stench trap. Also when two washbasins are arranged adjacently of each other and must be connected to one outlet pipe, it is necessary in the prior art to use different conduits and coupling pieces. The third chamber makes it possible to turn over the housing, whereby the outlet opening of the housing comes to lie on the underside. Because it is further possible to place the tubular insertion part in the second inlet opening, a stench trap is thus created wherein the outlet opening is situated on the lowest part of the housing. This is advantageous in the case of a relatively low outlet pipe in the wall. In an embodiment according to the invention with only two chambers, a part of the housing then protrudes below the connection to the wall. It is precisely for this reason that the embodiment with two chambers can protrude too far downward for a surround cabinet or drawer therein or in the case of a ceramic surround under a washbasin.

[0006] With the embodiment according to the invention with three chambers the housing protrudes downward little or not at all relative to the connection to the wall, and there is more space for instance for a drawer in a surround cabinet or a ceramic surround under the washbasin.

[0007] It is possible to arrange the insertion part and the outlet opening diagonally relative to each other, or both on the same side of the stench trap, and independently hereof it is possible here to opt to have the housing of the stench trap extend above or below the outlet opening.

[0008] Thus created is a stench trap suitable for all possible combinations.

[0009] In an embodiment of the stench trap according to the invention the tubular insertion part is provided on the free end with two connecting parts at right angles to each other and at right angles to the tubular insertion part.

[0010] Providing two connecting parts at right angles to each other on the tubular insertion part results in more choice for the connection of a washbasin outlet or sink outlet. It is thus possible for instance to have an outlet pipe run directly from a washbasin outlet to the wall and there connect to the stench trap either directly or via a pipe elbow, wherein a part of the outlet pipe runs parallel to the wall. In this latter case the outlet pipe in the wall does not lie in one line with the outlet opening in the washbasin. This can also be a desirable connection in the case of a second washbasin.

[0011] In a preferred embodiment of the stench trap according to the invention the tubular insertion part is further provided on the free end with a third connecting part, which third connecting part is arranged opposite one of the other connecting parts. The third connecting part further extends the different options for optimum connection of a washbasin or sink.

[0012] In another embodiment according to the invention the tubular insertion part has an oval-shaped cross-section. The oval-shaped cross-section makes it possible to reduce the thickness of the housing while retaining throughflow area. This does however have the consequence that the width of the housing increases. The advantage of a reduced thickness of the housing is that it creates more space under a washbasin or sink, whereby drawers for instance can be deeper.

[0013] In yet another embodiment of the stench trap according to the invention, wherein a removable inspection plug is arranged in the bottom of the first and second chambers. In the case of a three-chamber stench trap it is hereby possible to reach and clean all chambers.

[0014] These and other features of the invention will be further elucidated with reference to the accompanying drawings.

Figure 5 shows a cross-sectional view of the outlet according to figure 4 mounted in a second position under a washbasin.

Figure 6 shows a cross-sectional view of the outlet according to figure 4 mounted in a first position under a washbasin.

Figure 7 shows a perspective view of an embodiment not according to the invention.

Figure 8 shows an embodiment not according to the invention.

Figure 9 shows a second embodiment of the invention.

[0015] Figure 1 shows a first embodiment 1 of an outlet not according to the invention. This outlet 1 has a housing 2 with an outlet opening 3. Provided on the upper surface 4 of housing 2 is an inlet opening in which a tubular insertion part 5 is placed. Tubular insertion part 5 is provided on the free end with three connecting parts 6, 7, 8.

[0016] Figure 2 shows outlet 1 in cross-section. It will be apparent that a partition 9 is arranged in housing 2 which divides the housing into two chambers 10, 11. These two chambers 10, 11 are in liquid connection with each other on the underside. Because outlet opening 3 is at a higher position, a water trap is hereby created.

[0017] In figure 2 outlet 1 is mounted on a wall 12 in which an outlet pipe 13 is arranged. Outlet opening 3 of outlet 1 protrudes here into outlet pipe 13. Further arranged above outlet 1 is a washbasin 14, the outlet 15 of which is connected via a connecting pipe 16 to connecting part 7. Because connecting part 7 is height-adjustable through sliding in and out of the insertion part, it is possible to ensure that connecting pipe 16 lies as closely as possible against washbasin 14, and so a maximum space remains below washbasin 14.

[0018] Figure 3 shows a top view of outlet 1 mounted under a double washbasin 17. Outlet 1 is connected via outlet opening 3 to a pipe 18 in wall 19. Further shown in figure 3 is the top side of the insertion part with connecting parts 6, 7, 8. The two outlets 20, 21 of basins 22, 23 of washbasin 17 are connected to the respective connecting parts 8, 6 via connecting pipes 24, 25.

[0019] It will be apparent from figure 3 that it is possible with the outlet 1 to connect the outlet openings of reservoirs, such as washbasins or sinks, as efficiently as possible.

[0020] Figure 4 shows a first embodiment 30 of the invention. This outlet 30 has a housing 31, in which three vertical chambers 32, 33, 34 are arranged. Chambers 33 and 34 are closed on the top side by a cover 35 in which an inspection plug 36 is arranged. Chambers 33 and 34 are in liquid contact on the top side, as is also apparent from figure 5.

[0021] Arranged on the underside in the side wall of chamber 34 is an outlet opening 37 with which the outlet 30 can be connected to an outlet pipe 39 arranged in wall 38.

[0022] Chambers 32 and 33 are closed on the underside with a cover 40, and these chambers 32 and 33 are moreover in liquid contact with each other here.

[0023] Chamber 32 has at the top an inlet opening in which insertion part 41 can be placed. This insertion part 41 has an oval tube 42 with three grooves 43 in which a seal, such as an O-ring, can be placed. Connecting parts 44, 45 and 46 lying at right angles to each other and to oval tube 42 are arranged on the top side of oval tube 42.

[0024] As can be seen in figure 5, outlet 30 is arranged on wall 38 below a washbasin 47. Outlet 48 of this washbasin 47 is connected via a connecting pipe 49 to connecting part 45. Insertion part 41 is introduced here into chamber 32, whereby outlet opening 37 is situated on the underside. This configuration is particularly advantageous when pipe 39 is placed relatively low in wall 38, whereby it protrudes just above the bottom side of a ceramic cover 50.

[0025] Figure 6 shows outlet 30 arranged below washbasin 47, wherein pipe 39 in wall 38 debouches at a relatively high position. Outlet 30 is here turned over and insertion part 41 protrudes into the middle chamber 33. The inlet opening of chamber 32, which is now situated on the underside, is closed by means of a plug 51.

[0026] Outlet 48 of washbasin 47 is connected in the usual manner to insertion part 41 via connecting pipe 49.

[0027] Because outlet 30 is turned over and insertion part 41 has now been placed in middle chamber 33, a siphon taking up little space can still be provided on the wall despite the small height difference between outlet 48 of washbasin 47 and the opening of outlet pipe 39 in wall 38.

[0028] Figure 7 shows anembodiment of an outlet not according to the invention. This outlet 60 is a very simple embodiment. Outlet 60 has a housing 61 with an outlet opening 62. This outlet opening 62 can be coupled, for instance through insertion, to an outlet pipe arranged in a wall. Provided on upper surface 63 of housing 61 is an inlet opening in which a tubular insertion part 64 is placed. Tubular insertion part 64 is provided on the free end with a connecting part 65 directed toward the front.

[0029] Figure 8 shows an embodiment of the outlet according to the invention. In this embodiment washbasin 70 is mounted on a wall 71. An outlet opening 72 is provided on the underside of washbasin 70. A horizontal outlet pipe 73 leading to wall 71 is arranged on this outlet opening 72. This outlet pipe 73 debouches in an outlet 74 according to the invention. This outlet 74 forms the stench trap and is arranged against wall 71. Inserted into the underside of outlet 74 is a vertical outlet pipe 75 which connects to the outlet pipe 76 incorporated into wall 71.

[0030] In this embodiment outlet pipe 76 is at a low position in the wall. Because outlet 74 is arranged at a high position below washbasin 70 and because only a vertical pipe 75 lies against the wall, there is sufficient space below the washbasin for drawers 77. It is not necessary in this embodiment to provide drawers 77 with recesses, as is usual in the prior art.

[0031] A flat, for instance oval pipe is preferably used for the vertical outlet pipe 75.

[0032] The outlet has the advantage that a compact stench trap is provided which takes up little space and is suitable for any situation, irrespective of the height of the washbasin and irrespective of the connection in the wall. The invention can hereby be easily applied during renovation. It is usual here to hang a new washbasin higher than the original washbasin, this in order to take into account the increasing average height of people.

[0033] Figure 9 shows a second embodiment of a stench trap 80 according to the invention. This stench trap 80 has a housing 81 in which are formed a first chamber 82, a second chamber 83 and a third chamber 84.

[0034] First chamber 82 is in liquid communication with third chamber 84 via opening 85. An outlet opening 86 is provided in third chamber 84 diagonally opposite opening 85.

[0035] Second chamber 83 is in liquid connection with the first chamber via two openings 87 and 88 arranged on either side of chamber 83. An inlet opening 89, 90 is further arranged on either side in first chamber 82. Arranged on the top side in inlet opening 89 is a rubber plug 91 which is held in place with a cover 92. Placed in the inlet opening on the underside is a sleeve 93 which is held in place by a cover 94. A thickened portion 95 is arranged on sleeve 93, whereby the sleeve closes passage 88.

[0036] A tubular insertion part 96 is placed in sleeve 93. This insertion part 96 can slide reciprocally in sleeve 93 and thus compensate for height differences.

[0037] The advantage of this embodiment 80 is that the stench trap can be used in different positions by interchanging the plug 91 and the sleeve 93 with the tubular insertion part 96 therein. Outlet opening 86 can also be used as inlet opening and insertion part 96 can similarly be used as outlet opening instead of as inlet opening.
