Abstract

A siphon, particularly an odour trap for a waterless urinal, a floor drain and/or a shower tray or the like, including a tubular inlet and at least one outlet, the outlet opening of which can be opened and closed to a drain that can be connected by a valve. The valve includes a valve lever mounted in an articulated manner in the region of the inlet, which has an associated valve surface, wherein the valve surface seals the outlet opening in a form-fit and/or force-fit manner.

Claims

1. A siphon, in particular an odor trap for a urinal, a floor drain and/or a shower tray or the like, with a tubular inlet (1) and at least one outlet (2), the outlet opening (3) of which can be opened and closed in relation to a connectable drain pipe by means of a valve (4), characterized in that the valve (4) comprises a valve lever (6) which is mounted in an articulated manner in the region of the inlet (1) and has an associated valve surface (7), wherein the valve surface (7) sealingly closes the outlet opening (3) in a form-fitting and/or force-fitting manner.

2. The siphon as claimed in claim 1, characterized in that, in the use position, the outlet opening (3) points in a direction oriented laterally in relation.

3. The siphon as claimed in claim 1 or 2, characterized in that a seal (10) is arranged between the valve surface (7) and a sealing surface (11) of the outlet, said seal surrounding the outlet opening (3) in particular annularly and preferably being manufactured from an elastomer.

4. The siphon as claimed in claim 3, characterized in that the valve lever (6) comprises finger-shaped seals (10) which are formed, in particular integrally, with the valve lever and are manufactured from any material, for example, an elastomer.

5. The siphon as claimed in claim 3 or 4, characterized in that the finger-shaped seals (10) are arranged distributed on the outer circumference and/or over the surface thereof, in particular distributed about the outlet opening (3).

6. The siphon as claimed in one of claims 1 to 5, characterized in that the valve surface (7) and the sealing surface (11) have corresponding geometries, in particular the outer sealing surface (11) and the inner valve surface (7) correspond, or vice versa.

7. The siphon as claimed in one of claims 1 to 6, characterized in that the valve surface (7) is part of a valve cover (9) which is connected to the valve lever (6).

8. The siphon as claimed in one of claims 1 to 7, characterized in that the valve lever (6) and/or the valve cover (9) are/is acted upon by an actuating member, in particular a spring (22), a solenoid device, or a piston-cylinder arrangement, for opening and/or closing the outlet opening (3).

9. The siphon as claimed in one of claims 1 to 8, characterized in that the valve cover (9) is coupled to a free end of the valve lever (6) preferably via a joint in such a manner that said valve cover extends on both sides of the joint between the valve lever (6) and the siphon and also beyond the free end of the valve lever (6), or on one side of the joint between the valve lever (6) and the siphon.

10. The siphon as claimed in one of claims 1 to 9, characterized in that the joint between the siphon and the valve lever (6) and/or between the valve lever (6) and the valve plate (7) is designed as a hinge joint (5, 8).

11. The siphon as claimed in one of claims 1 to 10, characterized in that at least one spacer cam (15) which is effective for closing the outlet opening (3) is arranged between the valve lever (6) and the valve cover (9).

12. The siphon as claimed in one of claims 1 to 11, characterized in that the joint in the region of the inlet (1) is formed on a clip (16) which acts, in particular in a force-fitting manner, on the siphon, wherein the valve lever (6) and the valve flap (9) extend on the outer side of the siphon.

13. The siphon as claimed in one of claims 1 to 12, characterized in that the sealing surface (11) is curved convexly in its longitudinal extent.

14. The siphon as claimed in one of claims 1 to 13, characterized in that the inlet (1) is formed by an end-side or lateral opening in a pipe (18), the further profile of which has at least one bend (19), the free end of which forms the outlet opening (3) which is preferably surrounded by the sealing surface (11).

15. The siphon as claimed in one of claims 1 to 14, characterized in that the pipe (18) has a Y-shaped profile.

16. The siphon as claimed in one of claims 1 to 15, characterized in that the inlet (1) is formed by an end-side opening in a pipe, the opposite end side of which, from which a cone or a pyramid extends into the interior of the pipe, is closed, wherein at least one outlet opening (3) is formed on the circumferential side in the region of the closed end side.

17. The siphon as claimed in one of claims 1 to 16, characterized in that the inlet has a bulging cross section.

18. The use of a siphon as claimed in claim 1 on an, in particular waterless, urinal and/or a floor drain (27) and/or a bidet and/or a wash basin and/or a shower tray.

19. A floor drain as claimed in claim 18, characterized in that an adapter plate (26) which is provided with markings (28) and/or groove-shaped depressions (29) is arranged on the upper side, in particular on the inlet (1), wherein the markings (28) and/or depressions (29) serve as predetermined breaking points and/or aids for severing excess lengths at the edges in order to reduce the size of the adapter plate (26).

20. The floor drain as claimed in claim 18 or 19, characterized in that the adapter plate (26) serves as a holder of and/or centering for the odor trap.
