Description

Hygienic built-in components and corresponding uses

technical field

The invention relates to a sanitary insert part comprising at least two water guides, of which an outer water guide surrounds an inner water guide.

The invention further relates to the use of sanitary insert components.

Background technique

Such sanitary insert components are inserted into the outflow opening of the sanitary fitting, for example as a jet shaper and/or a jet regulator. The two water guides can, for example, guide different waters to the outflow opening. Examples of different waters can be: mixed water and cooking water, tap water and enriched water, mixed water and cooling water. Other examples are possible.

SUMMARY OF THE INVENTION

The object of the present invention is to improve the performance characteristics of sanitary inserts of the type mentioned.

In order to solve this task, a sanitary fitting is proposed, which comprises at least two water guides, an outer water guide surrounding an inner water guide, characterized in that the inner water guide is formed in the A flow barrier that creates, at least in part, a laterally directed flow. In particular, it is therefore proposed according to the invention in sanitary inserts of the type mentioned at the beginning that flow barriers are formed in the inner water guide, which flow barriers at least partially generate a laterally directed flow, in particular a radial flow. It can thus be achieved that the flow of the inner water guide expands radially and, for example, forms a jet width which corresponds to the flow of the outer water guide. The formation of a flow impediment can also cause the pressure drop upstream of the built-in part to not be too great due to backflow. A large pressure drop can cause undesired steam generation eg when delivering cooking water, ie (superheated) liquid water eg having a temperature above 100°C (or above the atmospheric boiling point). This can lead to uneven impingement flow.

In an advantageous configuration it can be provided that the flow barrier has laterally directed outlet openings. A simple mechanism for generating a laterally directed flow is thus depicted.

For example, the laterally directed outlet openings may be oriented radially. This enables radial flow.

In an advantageous design, it can alternatively or additionally be provided that the flow barrier has a forwardly directed outlet opening. A part of the flow in the inner water guide can thus be discharged unhindered or almost unhindered. In this way, for example, the desired backflow characteristic can be easily adjusted or reduced.

For example, the forwardly directed outlet opening can be oriented axially. Axial flow can thus be created.

The combination of laterally directed discharge openings and forward, ie axially directed discharge openings enables good filling of the downstream mixing chamber. The mixing chamber can here have a larger clear width than the inner water guide.

In an advantageous configuration, it can be provided that the flow barrier is designed in the shape of a pot. A laterally and forwardly directed discharge opening can thus be formed in a simple manner.

In an advantageous configuration, it can be provided that a mixing chamber is formed downstream of the flow barrier, in which mixing chamber the outer water guide and the inner water guide meet. A uniform or at least similar jet pattern can thus be achieved for both water guides.

In an advantageous configuration it can be provided that the mixing chamber is bounded by a common outflow structure for the at least two water guides. A common, identical or at least similar jet shaping for the at least two water guides can thus be achieved.

In an advantageous design, it can be provided that the impingement plate is arranged downstream of the flow barrier. Thus, smoothing of the water can be achieved.

In this case it can be provided that the forwardly directed outlet openings point towards the impact plate. It is thus possible to prevent the forwardly directed flow from escaping from the insert part without hindrance.

In an advantageous design it can be provided that the mixing chamber has at least one ventilation window. This allows the entry of suctioned air in order to enrich the water jet with small air bubbles.

In an advantageous configuration, it can be provided that in the outer water guide at least one acceleration nozzle is formed on the inlet opening into the mixing chamber. A ventilated jet can thus be produced in the outer water guide.

In an advantageous configuration, it can be provided that a partition is formed which surrounds and/or encloses the flow barrier. Jet shaping of the discharged water can thus be achieved. It is possible here for the partition to cover the ventilation window for the laterally directed flow. The discharge of the laterally directed flow from the at least one ventilation window can thus be avoided.

In an advantageous design it can be provided that the grid insert is arranged in the mixing chamber. Therefore, the mixing can be improved.

It can be provided here that the grid insert has a central hole which is larger than the size of the inlet of the inner water guide into the mixing chamber. It can thus be avoided that the flow of the inner water guide is directed directly onto the grid insert. This can be advantageous, for example, when the cooking water is guided in the inner water guide. It is also advantageous here that the recombination of the jets in the interior can be reduced, so that special jet shaping can be achieved.

In an advantageous design, grid inserts can be provided in the mixing chamber. The mixing in the mixing chamber can thus be aided.

It can be provided here that the impact plate is formed on a grid insert, in particular already mentioned. Thus a simple provision of impact plates is depicted. Additional parts for setting or securing the crash plate can be dispensed with, and assembly steps can be avoided.

In an advantageous configuration, it can be provided that the sleeve forming the inner water guide is clamped into a splitter unit in the outer water guide, which constitutes at least one, in particular the at least one already described. Speed up the nozzle. This enables simple assembly with high mechanical stability.

In an advantageous configuration, it can be provided that the inner water guide at its input end forms a socket for the insertion of the connecting line. Thus, the connecting conduit can be fastened without clamps or without additional connecting elements.

In an advantageous configuration, it can be provided that the sleeve and the flow barrier are connected in one piece. Simple manufacturing is thus possible and the flow barriers remain reliable and sealed. It can even be provided that the sleeve and the bowl are connected in one piece.

It is advantageous here that leakage flows into the outer channel can be avoided. Undesirable heating of the fittings during operation can thus be avoided or at least reduced.

An advantageous use of the invention relates to the use of the inner water guide of the sanitary insert part according to the invention, in particular as described above, for conveying cooking water or treated water and/or the claimed hygienic built-in components.

In addition to cooking water, other treated waters are also possible. For example filtered, cooled, admixed with a gas such as carbonic acid, provided with flavorings and colors such as lemon juice, fruit juice . . . It is advantageous here that gas evolution can be delayed. The insert part according to the invention can therefore be used universally.

For example, an external water guide can be used to convey the mixed water.

Detailed ways

1 to 7 are collectively described below.

The hygienic insert part, which is designated as a whole by 1 , is formed by way of example as a jet shaper and/or a jet regulator 2 and is inserted into the outflow pipe 3 of the sanitary fitting 4 for the use position shown in FIG. 5 , for example Hold, screw in or clamp by other components.

FIG. 5 shows by way of example the fastening of the sanitary insert 1 with the inlet piece 44 , which is fastened to the outflow pipe 3 by means of the screw connection 43 . The sealing means 42 seal outwards.

The inflow side 5 and the outflow side 6 of the sanitary insert 1 are connected by two water guides 7 , 8 which are partially separated from each other and are connected in parallel to each other. The water from the two water guides 7 , 8 is thus discharged from the outlet opening 9 of the sanitary fitting 4 .

Here the outer water guide 7 is designed such that it surrounds or encloses the second inner water guide 8 . Each of said water guides 7, 8 thus forms a channel. In the outer water guide portion 7 , water flows along the outer flow path 39 , and in the inner water guide portion 8 , water flows along the inner flow path 38 .

The outer water guide 7 is supplied by the outer water conduit 36 in the outlet pipe 3 and the inner water guide 8 is supplied by the inner water conduit 37 . The water conduits 36, 37 extend separately from each other to an associated valve (not shown).

A flow barrier 10 is provided in the inner water guide 8 , which constitutes an additional flow resistance for the flowing water.

The flow barrier 10 is designed in such a way that a laterally directed flow 11 is produced, by means of which the water flow of the inner water guide 8 widens.

In the embodiment shown, the flow 11 is a radial flow, however in other embodiments a flow is produced in other laterally directed directions oriented transverse to the longitudinal axis.

As a result of this expansion, a jet with a jet width 13 is produced, which is equal to the jet width of the flow through the outer water guide 7 .

A backflow on the inflow side 5 is produced by the flow barrier 10 , which leads to a reduction in the pressure drop in the outflow pipe 3 . This prevents the formation of air bubbles in the outlet pipe 3 when the superheated water reduces the pressure. Through the superheating, it is possible to achieve that the cooking water which is discharged at the outflow opening 9 is close to 100°C.

The flow barrier 10 is pot-shaped and has a laterally directed outlet opening 15 in its pot wall 14 . These discharge openings 15 divert a portion of the liquid in the inner water guide 8 in the radial or lateral direction.

The flow barrier 10 furthermore has a forwardly directed outlet opening 17 in its tank bottom 16 , here axially.

The inner flow path 38 is thus divided into a laterally (here radially) directed flow 11 and a forwardly (here axially) directed flow 40 .

A mixing chamber 18 is formed downstream of the flow barrier 10 , into which the two water guides 7 , 8 open. The mixing chamber has a larger clear width (measured transversely to the longitudinal axis 12 ) than the inner water guide 8 .

The outflow structure 19 delimits the mixing chamber 18 to the outside and in particular on the outflow side 6 .

Below the flow barrier 10 is formed an impingement plate 20 which is fed through the forwardly directed outlet opening 17 .

The mixing chamber 18 also has at least one ventilation window 21 through which air can be drawn into the mixing chamber 18 . A vented water jet is then produced, which contains small air bubbles. The ventilation window 21 is formed on the pot-shaped lower part 45 of the sanitary insert part 1 .

In order to generate a negative pressure in the mixing chamber 18 , by means of which air is sucked in via the ventilation windows 21 , acceleration nozzles 22 in the orifice plate 23 are formed in the outer water guide 7 . The orifice plate 23 is part of the resolver unit 30 which snaps or clips with the lower part 45 .

A circumferential partition 24 is formed between the laterally directed outlet opening 15 and the ventilation window 21 . The baffle 24 has dimensions along the longitudinal axis with which the ventilation window 21 for the laterally directed flow 11 is covered.

In addition, at least one grid insert 25 , 41 is arranged in the mixing chamber 18 , which grid insert separates the jets in the water guides 7 , 8 and thus leads to an improved mixing of air and water.

The grid insert 25 has a central hole 26 which avoids the area of direct inflow through the inner water guide 8 . The dimension 27 of the inlet 28 of the inner water guide 8 is here smaller than the dimension of the central bore 26 .

The already mentioned crash plate 20 is here formed in one piece with the second grid insert 41 .

On the inflow side, the inner water guide 8 has a sleeve 29 which is clamped into the splitter unit 30 , here the orifice plate 23 .

Here, the plate-shaped resolver unit 30 is clamped between the stop 31 and the latching projection 32 .

On the inflow side, the sanitary insert part 1 has a socket 33 in the inner water guide 8 , into which a connecting line 34 or connecting pipe is inserted. The connecting line 34 or the connecting pipe can here be provided with a sealing ring 35 which seals against the sleeve 33 .

The bowl can also be connected in one piece with the resolver unit 30 . Separation or connection depends on the proportions used and the method of manufacture.

In an advantageous use of the invention, the cooking water flows in the inner water guide 8, which can be heated to more than 100° C. by the high working pressure in the inner water guide 8 without will evaporate. In the outer water guide 7, the mixed water flows out of a mixing drum (not shown).

It is therefore proposed in the sanitary insert part 1 that a flow barrier 10 is formed in the inner water guide 8 , by means of which a part of the flow is deflected in the lateral direction.
