Abstract

The present invention relates to a kit for making water odor seal in a floor drain consisting of a combination of two structural elements (11, 25) i.e. a first structural element (11) made as a generally known open-bottom U-channel and a second structural element (25) made in a generally known method as a bell-like body with a free edge reaching into the channel (11), whereby said first structural element (11) is provided on its outer side with a sealing element, such as a sealing ring (13) fitted into a ring-shaped groove (12).

Description

DRAIN

Technical field

The invention relates to a kit for forming an aqueous odor seal.

BACKGROUND OF THE INVENTION

In the case of drains with a water odor closure, there is a problem that whenever the drain is not used for a long time, it can dry out. Through the dried water seal, the channel gases get out and there is an intense odor load. This occurs, for example, in holiday homes and hotels that have not been used for a long time.

GB-A 2 134 940 discloses a drain in which, in order to solve the above-mentioned problem, a bell-shaped float is arranged in a multi-part body, movable upwards and downwards, and a water cushion is formed between the body and the mouthpiece to form an aqueous odor closure. in which the lower edge of the bell-shaped float is immersed,

If the water contained in the water cushion forming the annular channel dries, the float sinks to a rate corresponding to the loss of water until it finally closes the flow opening formed by the nozzle, closed when the float sinks, so that the gases exiting the duct are retained through the inlet . The flow opening is again released by lifting the float, and the water can flow freely through the flow opening to the drain opening and through it into the channel.

SUMMARY OF THE INVENTION

The present invention is based on the task of providing a simple remodeling option for existing effluents with a conventional water-odor trap so that no leakage of channel gases occurs even after drying

31511 T drain. In particular, it is intended to provide a wide range of applications, irrespective of the bodies and drains formed.

This problem is solved by combining two structural members, namely the first structural member formed as a gutter, open-ended, as a one-piece U-shaped body forming a known annular channel, and the second structural member formed in a known manner as a bell-shaped body whose free edge extends into the annular channel.

For reliable guidance of the float in the vertical direction, the first component is preferably provided within the trough with guide rails for guiding the second component.

For particularly simple installation into the body or tube, etc. the first component on the outside is provided with a sealing element, for example an annular seal inserted in the annular groove.

Preferably, the second structural member is formed as a hollow body and is filled with a material lighter than water.

However, it is also possible to make the float from a material that is lighter than water.

In order to achieve a particularly efficient drainage of water by means of the suction effect, it is advantageous to provide the first component with a stop plate arranged below the central passage of the first component, the stop plate preferably being designed as a conical stop plate.

The impact plate is preferably integrally formed with the first component.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail by way of example of embodiment shown in the drawings, in which FIG. 1 shows a section through an outlet, FIG. 2 shows a detail of the outlet on an enlarged scale, and FIG. 3 a slightly modified creation, also in section.

DETAILED DESCRIPTION OF THE INVENTION

The floor drain shown in the drawing has a two-part body 1, namely a body part 3 carrying a drain hole 2, which according to FIG. 1 formed by a tubular part 4 extending laterally in a horizontal direction away from the body or according to FIG. In this first body part 3, another body part 6, which carries the inlet opening 7, can be inserted by means of an outer annular seal 8 sealed against the first body part 3. This second body part, which also carries a lattice 9 covering the inlet opening 7, to prevent the entry of larger pieces into the drain, can be extended, depending on the requirements arising from the installation as a result of different tile heights and tile thicknesses, etc. this second body part 6 on the outside of the annular groove 10, into which, depending on the depth of installation of the second body part 6, an outer annular seal 8 can be fitted in the first body part 3 and along which the second body part can be cut.

A second structural element 11, hereinafter referred to as an insert, is inserted into the second body part 6 and, like the second body part 6, is formed radially symmetrically. It carries an annular groove 12 with an annular seal 13 at its upper end, so that it is sealed against the second body part 6 in the mounted state. This insert 11 has a cylindrical wall 14 extending downwardly parallel to the wall of the second body part 6, which extends through a rounding 15 into an approximately horizontal

31511 T extending the bottom wall 16 of annular annular shape that extends radially inwardly from the first wall 14. This annular annular wall 16 passes again through a rounding 17 into a vertically extending tubular portion 18, the upper end 19 of which forms a flow opening 20. Thus, the insert 11 forms an upwardly open space as a water cushion. At the lower end of the insert 11, a conical-shaped impact plate 23 is provided, fixed by means of the webs 21 at a distance 22, so that the water flowing through the flow opening 20 is deflected radially outwards.

Inside the liner 11 there are radially inwardly and vertically upwardly extending guide rails 24 for the second structural member formed as a float 25 having a bell-like shape and overlapping the upwardly protruding tubular portion 18 of the liner 11. This float 25 is lighter than water and is formed, for example, as a hollow body. This bell-shaped float 25 has an upper part 26, which is preferably plate-shaped. It is arranged so that it can rise and fall in the insert 11 and is guided in the vertical direction by means of guides 24. The upward movement of the float 25 is limited by a stop 27 arranged on the second body part 6, which is preferably formed by a head grate. Its downward movement is limited in that its top 26, i.e. the plate, abuts the upper end 19 of the tubular portion 18, thereby covering the flow opening 20. The upper end 19 of the tubular portion 18 is in good tightness with the upper portion 26 of the bell float. 25 formed as a relatively narrow hem.

The drain function is as follows:

When the water flows through the inlet opening 7 into the drain, it enters the insert 11 and is guided by the interaction of the bell float 25 and the insert H, which form a siphon. The water rises in the liner 11 and presses the float 25 against the upper stops 27. Further, the incoming water flows through the flow opening 20 and reaches through the drain opening 2 into the channel.

If the water present in the liner H dries (evaporation), the float 25 sinks downwards, depending on the decreasing amount of water.

31511 T part 26 closes the flow opening 20. This prevents the backflow of gases at the outlet through the flow opening 20 and the inlet opening 7.

The invention is not limited to the illustrated embodiment, but may be modified in various respects. The float 25 need not be formed as a hollow body. It can be made of a material lighter than water. Furthermore, the hollow space contained in the float 25 may be filled with material to prevent water entering the hollow space in case of damage to the float 25. It is also possible to provide a drain with a nozzle provided with a drain hole 2 as shown, for example, in AT-B 393 397th

Kit consisting of first and second structural members 11 and 25, i. formed from the liner 11 and the float 25, can also be used without a specially made body 1; for example, it could be inserted into a pipe or a fitting, in which case the pipe or fitting assumes the function of a body.
