Description

6 5 5 8 A WATER TRAP OF THE INNER-SYPHON KIND The present invention
relates to a water trap of the inner-syphon kind comprising a bowl-shaped lower part and a detachable funnel-shaped insertion the exterior circumferential dimension at the lower end of which is smaller than the interior circumferential dimension of the bowlshaped lower part an,., which is adapted to be inserted from above into the bowl-shaped lower part, and to protrude down into the bowl and to end at a distance f rom the bottom thereof by means of distance ribs keeping the upper end of the insertion at a distance from the upper end of the bowl-shaped lower part while forming outlet apertures between the two parts.
It has turned out that it rapidly can happen that the distance ribs are gathering dirt particles in such considerable quantities that this results in an undesirable blocking up of said outlet apertures. The object of the invention is to state how to obviate this inconvenience.
According to the invention this is obtained by the fact that at least opposite to the distance ribs between the funnel-shaped insertion and the bowl-shaped lower part are placed partition walls dividing the annular space formed between the insertion and the lower part into separate flow sections.
These partition walls make it possible to confer the outgoing water such a course of flow that an inconvenient deposit of dirt particles in the area around the distance ribs is avoided.
According to the invention, a particularly advantageous embodiment of the water trap is carried out in such a way that the volume of said annular space which is limited by a part of the funnel-shaped insertion is smaller than the volume of the inner space of the insertion which is limited by the same part, and that the partition walls extend at least along a substantial part of the lower end of the insertion.
These particular volume conditions are resulting in 2 that the water pressure of the water leaving the trap is increased. The combination of that feature with the placing of the partition walls which is characteristic of the invention results in that the water trap is very well kept clean as deposits of dirt particles ane concerned. In traditional water traps having no such partition walls inconvenient deposits of dirt particles around the distance ribs will occur even if the water pressure is increased.
An embodiment of the water trap according to the invention will now be explained more explicitly with reference to the drawing in which:
Fig. 1 is a schematic longitudinal section through the water trap, and Fig. 2 is a cross-section following the line II-II of Fig. 1.
The water trap of the inner-syphon kind shown on the drawing comprises a bowl-shaped lower part 10 and a funnelshaped insertion 12 which is detachable and inserted from above into the lower part 10. The insertion 12 has a substantially truncated cone-shaped upper part 14 and a cylindrical lower part 16.
At the bottom, the lower part 10 has a bowl-shaped part 18, and at the top a ring-shaped part 20 which, by means of distance ribs 22, is connected with the part 18 so that between the parts 18 and 20 are formed outlet apertures which are marked by the arrows 24 and the side limitations of which are formed by the ribs 22.
When the insertion 12 is inserted into the lower part, its upper part, by means of not explicitly described shoulders, is resting on corresponding counter-shoulders of the ring-shaped part 20 of the lower part 10. The lower part 16 of the insertion 12 ends - as shown - at a distance from the bottom 26 of the lower part 10. Together with part 18 of the lower part 10, part 16 defines a ring-shaped flow space 28 in such a way that the water flowing in from above through the insertion again can leave the water trap via 3 the annular space 28 and the outlet apertures 24.
In the embodiment shown, partition walls 30 are placed on the outside of the insertion 12 which are positioned opposite to the distance ribs 22 and which, in the embodiment shown, are extending all the way down over the lower part 16 of the insertion 12. By means c.. these partition walls, the annular space 28 is divided into separate flow sections 28a as it best does appear from fig. 2. Hereby are provided such courses of flow which counteract the deposits of dirt particles from behind in the area around the distance ribs 22.
The volume of the annular space 28 is smaller than the volume of part 16 of the insertion 12 by means of which an increased water pressure is produced in the annular space. This can perfectly be utilized to keep the outlet apertures 24 more clean.

CLAIMS. >,
1. A water trap of the inner-syphon kind comprising a bowl-shaped lower part and a detachable funnel-shaped insertion the exterior circumferential dimension at the lower end of which is smaller than the interior circumferent-L;l eAmension of the bowl-shaped lower part to form a ring-shaped flow space, and which is adapted to be inserted from above into the bowl-shaped lower part, and to protrude down into the bowl and to end at a distance from the bottom thereof by means of distance ribs keeping the upper end of the insertion at a distance from the upper end of the bowlshaped lower part while forming outlet apertures between the two parts, characterized in that at least opposite to the distance ribs between the funnel-shaped insertion and the bowl-shaped lower part are placed partition walls dividing the annular space formed between the insertion and the lower part into separate flow sections.
2. A water trap according to claim 1, characterized in that the partition walls are placed on the outside of the funnel-shaped insertion.
3. A water trap according to claim 1 or 2, characterized in that the volume of said annular space which is limited by a part of the funnelshaped insertion is smaller than the volume of the inner space of the insertion which is limited by the same part, and that the partition walls extend at least along a substantial part of the lower end of the insertion.
