Description

I
Set of components for the modular construction of an outlet assembly The invention relates to a set of components for the modular construction of an outlet assembly for removing water drained from a drinking water system into a waste-water pipe. The component set comprises an upper outlet body provided with lateral openings and adapted to be connected to an outlet of the drinking water system, and a lower outlet funnel which is arranged in alignment with the upper outlet body and adapted to be connected to the waste-water pipe.
There are fittings in drinking and service water systems which are used to drain water under certain conditions to an outlet. Examples are pipe disconnectors which disconnect a service water system (heating) from a drinking water system and prevent a backfiow from the service water system into the drinking water system. If such a backflow occurs the outlet valve is opened so that the backflowing water is drained into a waste-water pipe. Other examples are pressure relief valves, which open if there is a high pressure in the water system and drain water into the waste-water pipe. An outlet assembly is provided for this purpose which usually consists of a system side upper outlet body and an outlet funnel arranged therebelow. The outlet body is a downwardly open hollow body with lateral openings which is connected to an outlet socket in the drinking- or service water system. Excess water flows into the outlet body, the inner space of which is connected to atmospheric pressure through the lateral openings. An outlet funnel is provided under the outlet body which is connected to a waste-water pipe. The waste-water pipe is connected to the sewers. In order to avoid bad smells a syphon is normally provided in the waste-water pipe forming a smell barrier. It is also necessary to avoid rising waste-water coming out of the outlet funnel. However, there are assemblies without syphon. In such assemblies a smell barrier is provided in the form of a valve like a backflow preventer. The outlet assemblies according to the prior art of this kind are complicated and expensive.
It is an object of the invention to facilitate the assembling of such outlet assemblies and to make them less expensive.
According to the invention this object is achieved in that (a) the lower rim of the outlet body is adapted to be removably connected to the upper rim of the lower outlet funnel, (b) the set of components is provided with a backflow safety device with a valve opening towards the outlet direction and blocking the opposite direction, and (c) the lower outlet funnel defines a receiving unit, which is adapted to optionally sealingly accommodate the backflow safety device.
In such a way a set of components is provided where the upper outlet body and the lower outlet funnel can be used without any further backflow safety device. This is the common installation, if, for example, a syphon is provided in the waste-water pipe.
The components are used in large numbers and, therefore, allow a cheap production thereof. The components, however, are now initially designed in such a way, that they allow also a modular construction of an outlet assembly without significant effort, which component set comprises a backflow safety device. For this purpose the set of components comprises a backflow safety device in the form of an integral component as a third component. The two other components are designed in such a way that they can he easily detached and the lower outlet funnel defines a receiving unit, which is adapted to optionally sealingly accommodate the backflow safety device.
Further modifications of the invention are subject matter of the subclaims. An embodiment of the invention is described hereinbelow in greater detail with reference to the accompanying drawings.

In Fig.! an upper outlet body is denoted with numeral 10. The outlet body 10 has a generally conical shape with a downwardly increasing diameter. At its upper end the outlet body 10 is connected to an outlet socket (not shown) of a water fitting by means of a fastening nut 12 and a clamping ring 14 (Fig.4). A lower outlet funnel 16 is arranged in alignment with and under the outlet body 10. The outlet funnel 16 is connected to a waste-water pipe (not shown) by means of a fastening nut 18 and a clamping ring 14 (Fig.4). The waste-water pipe is connected to a sewer and normally comprises a smell barrier in the form of a syphon. The outlet body 10 and the outlet funnel 16 are easily removably connected by a bayonet coupling. Numeral 22 denotes a backflow safety device. This is used to interrupt the connection to the sewer if no syphon is installed in the waste-water pipe and thereby avoid bad smells. Furthermore waste water can be prevented from rising from the waste-water pipe and coming out of the outlet assembly.
The outlet body 10 is provided with a socket-like upper section 24. A ring 26 is connected to the section 24 by conical webs 28 and 30. The webs 28 and 30 border lateral openings 32 and 34. These openings 32 and 34 ensure that the outlet socket is directly connected to the atmosphere when the fitting side outlet valve opens and is pressurised with atmospheric pressure. The outlet body 10 is provided with downwardly extending projections 36 (Fig.6). These projections extend inwardly from the inner wall of the section 24 and extend axially towards the side of the outlet with a tip 38. These projections 36 ensure a well defined flowing of the water from the outlet socket into the outlet funnel.
The ring 26 of the outlet body 10 extends around a flange 40 at the upper edge of the outlet funnel 16. This flange 40 is provided with two diametrically opposite circumferential slits 42 and 44, extending in the same direction. The circumferential slits 42 and 44 are connected to insertion recesses 46 and 48, respectively. On the inner side of the ring 26 two diametrically opposite pins are provided, only one 50 of which can be seen in Fig.!. In use, the pins 50 locate into the insertion recesses 46 and 48 and slide into the circumferential slits 42 and 44, respectively when the portions 10 and 16 are rotated relatively to each other. Small circumferential slits 52 and 54, adjacent to the circumferential slits 42 and 44, respectively, allow the elastic opening of the circumferential slits 42 and 44, respectively whereby the pins 50 are clamped in the circumferential slits. Thereby a bayonet locking is effected which allows a quick assembly and disassembly of the outlet body 10 and the outlet funnel ! 6.
In such a way the outlet body 10 and the outlet funnel 16 can be assembled by themselves, i.e. without backflow safety device, especially if there is a smell barrier in the form of a syphon mounted in the waste- water pipe.
A backflow safety device 22, however, can easily be inserted then or at a later stage, if this is necessary.
For this purpose a cylindrical section 56 is provided at the inner wall of the outlet funnel next to the upper rim. The section 56 can also comprise the inner wall of the flange 40. A step is provided next to the cylindrical section 56. The section 56 and the step 58 form a receiving unit for the backflow safety device in the outlet funnel 16.
The backflow safety device is provided with a cup-shaped insert portion 60. The insert portion 60 is radially held in the cylindrical section 56 and sits on the step 58 with a rim 62. An annular groove 64 is formed on the outer surface of the insert portion 60 accommodating a sealing ring 66 (Fig.8). In this way the backflow safety device 22 is adapted to be sealingly inserted into the cylindrical section 56.
The backflow safety device 22 forms an integral component. The insert portion 60 has a rim 62 with a truncated conical, downwardly narrowing outer surface and altogether a corresponding truncated conical, downwardly narrowing inner surface. The insert portion 60 is essentially open on the bottom. The bottom 68 forms two sector-shaped openings 70 and 72 each extending almost about an angle of 180 . The openings 70 and 72 form a web 74 therebetween. The web 74 carries a central guiding ring 76. A rod 78 is guided through the central guiding ring 76 from below. At its lower end the rod 78 is connected to a plate 80 which is fixedly attached to the rod 78. A flexible rubber disc with a slightly larger diameter lies on the plate 80. The rubber disc covers the openings 70 and 72 from below and normally abuts the lower surface 82 of the insert portion 60. The rubber disc forms a valve plate 84. The rod 78 is provided with a thread at its upper end. The rod 78 is surrounded by a relatively weak helical spring 88. The helical spring 88 is supported on the guiding ring 76 and acts upon a head 90.
The head 90 is screwed onto the thread 86 with a threaded hole. In operation the helical spring 88 pulls the rod 78 with the disc 80 and thereby the valve plate 84 upwards. In this way the valve normally is held tightly closed. Smells cannot leak from the outlet pipe. Waste-water potentially rising from the waste-water pipe also acts to push the valve into a closed position and, thereby, cannot leak from the outlet assembly.
If water flows out of a drinking- or service water system through the outlet socket this water is collected in the cup-shaped insert portion 60. Due to the weight of the water the valve 84 is pushed open overcoming the weak helical screw 88. This allows water S to flow out.
