Device &tgr;,&ngr;* introducing*» water in a pipe ia a storage

The present invention relates to a device for introducing water carried in a pipe into a reservoir, in which a further pipe leading to the reservoir branches off from the pipe in the region of a siphon which maintains a water level in its interior.

Such a device is part of the applicant's internal state of the art; siphons are known as odor traps in sewage pipes.

It is also known to collect rainwater in storage tanks, which is brought there from a gutter via a downpipe. With the

* Stored rainwater can be used, for example, to flush toilets.

% To date, these rainwater collection devices have

' On the one hand, the problem of blockage caused by leaves being carried along,

<·, on the other hand, the problem of overcrowding during heavy rain

tion.

The present invention is therefore based on the object of creating a | ^; device according to the preamble of the main claim,

\ where neither leaves get into the storage nor does it become overfilled during heavy rain.

"*· " * &mdash;2&mdash;

The solution to the problem lies in the fact that the line branch in the flyphone is provided below the maximum water level.

This has the advantage that leaves floating on the water level do not get into the further pipe and are thus kept away from the storage tank. Water in the torrential rain flows through the siphon into the drain, opening up to the further pipe.

In an embodiment of the invention, it is proposed that the line branch be provided in a section of the siphon, which is internally limited by a discharge line that is almost flush with the inlet. This embodiment results in a particularly simple and cost-effective design of the siphon.

In a further embodiment of the invention, the inlet and the annular space are connected to one another via a hollow truncated cone. This enables the siphon to be formed as a pressed part.

Furthermore, it is particularly useful to arrange the cable branch at a distance from the floor of the hanging room so that it can be replaced. This makes it easy to replace in the event of servicing.

In another embodiment of the siphon, it is particularly advantageous to arrange the pipe branch at the lower beginning of a flow reversal section in the siphon. This makes it particularly effective to keep foreign particles that are washed away by the rainwater away from the storage tank.

It is particularly advantageous here for the pipe branch to be designed at its beginning as a hollow vessel with at least one slot. As a result, the main flow and the flow to the storage tank are in opposite directions. In this case, the pipe inlet opening is preferably closed with a cover.

Finally, it is particularly useful to provide a drainage opening between the pipe branch and the slot end. This defines a minimum low water level in the siphon for frost protection reasons.

Further embodiments and particularly advantageous further developments of the invention will become apparent from the following description of two exemplary embodiments of the invention with reference to Figures 1 to 3 and the drawing:

-.In all three figures, the same reference symbols indicate the same details.

A house 1 - preferably an apartment building, hotel or partly used for commercial purposes - has a roof 2 which is drained via a gutter 3 to which a downpipe k is connected. A pipe 5 in which a siphon 6 is provided is connected to the downpipe *f. A further pipe 8 branches off from the siphon 6 at a branch 7, which leads to a storage tank 9 which is provided with an overflow 10. A discharge pipe 11 branches off from the storage tank 9, in which a pump 12 and a pressure vessel 13 are arranged, to which a consumer pipe 1^f leading to toilet flushes is connected.

The siphon 6 according to Figure 2 is designed as a plastic press or cast part. A hollow truncated cone 21 is connected to the downpipe k or the first part of the line 5 connected thereto, concentrically surrounding a discharge line 20, an annular space 22 being formed between its inner diameter and the outer diameter of the discharge line 20. Below the truncated cone is a cylindrical shell 23 which is closed by a base 2h through which the discharge line 20 fits tightly. The cylindrical shell is penetrated by the branch 7 at a distance from the base 2k , this connection of the line 8 being designed to be replaceable. An annular gap 25 extends between the upper end 28 of the discharge line 20 and the inner diameter of the truncated cone 21, which also defines the minimum water level 26.

-k-

The water flows to the interior 27 of the siphon 6 via the pipe k ; in the case of low water flow, it circulates on the inner wall of the pipe β k . This water reaches the upper beginning of the pinhole 22 via the inner jacket of the truncated cone. Washed-down leaves remain on the surface of the gauge and are washed away into the discharge line ?o. Water is led to the reservoir via the branch 7 and the pipe ^ nhp;n . If surge water reaches the siphon 6 via the downpipe k , it falls through the interior ,'.'7 more c"i-:r less into the discharge _line ^2Ö which is aligned with the pipe 4.

Between the bottom 2k and the branch 7 there is an outflow opening 4o in the discharge line 2o , which defines the minimum water level 26 in the syphon 6.

According to the embodiment ^example shown in Figure 3, the SyboD 6 consists of three parallel pipes 30 to 32 which are placed next to each other and are connected to each other via two bends 33 and 34 , whereby a flow direction is obtained according to the arrow 35. The flow through the pipes 30 and 32 is downwards, for which the middle pipe 31 is used.

There is a flow reversal section in the siphon, in which the 5

Branch 7 is provided at its beginning. The branch consists of an S- 1

shaped tube, with the middle part of the S forming the wall 41 |

of the siphon. The inflow end 37 of the S-shaped |

Tube 36 1st closed with a cover 38 and with one or *

several slots 39, which are only partially covered by the cover. They form the actual branch, which leads to the further ;|

line 8. Below the end kP. of the contactor 39, a discharge opening *fO is provided, which defines the minimum level stsjad 26. B

The function of this siphon is as follows: Water flowing in through the line k or 5 flows through the pipes 30 to 32 one after the other. The water which does not flow through the slots 39 to the further line 8 passes into the continuation of the line 5. The slot or slots 39 act as a sieve so that impurities are largely kept away from the further line 8.
