Definitions
- the invention relates to a sanitary insert with at least two water channels, with an outer water channel surrounding an inner water channel.
- Such sanitary inserts are used, for example, as a jet shaper and/or jet regulator in an outlet of a sanitary fitting.
- the two water channels can, for example, lead different waters to the outlet. Examples of different waters can be: mixed water and boiling water, tap water and fortified water, mixed water and chilled water. Other examples are possible.
- the invention further relates to the use of a sanitary insert.
- the object of the invention is to improve the functional properties of a sanitary insert of the type described.
- a flow obstacle is formed in the inner water supply, which at least partially generates a sideways flow, in particular a radial flow. It can thus be achieved that the flow of the inner water channel widens radially and, for example, forms a consistent jet width with the flow of the outer water channel.
- the formation of a flow obstruction can also cause a pressure drop upstream of the insert does not become too large because of a backlog. Large drops in pressure can, for example, cause undesired vapor development when boiling water is passed through, for example (superheated) liquid water with a temperature above 100 °C (or above the atmospheric boiling point). This can result in an uneven, jerky flow.
- the flow obstacle has outlet openings directed sideways.
- outlet openings directed sideways can be aligned radially. A radial flow can thus be achieved.
- the flow obstacle has outlet openings directed forward. A part of the flow in the inner water supply can thus escape unhindered or almost unhindered. In this way, for example, a desired backwater behavior can be easily set or reduced.
- the forward exit ports may be axially aligned. An axial flow can thus be generated.
- outlet openings directed sideways and outlet openings directed forward makes it possible to fill a mixing chamber located downstream well.
- the mixing chamber can have a greater clear width than the inner water supply.
- the flow obstacle is designed in the shape of a pot. In this way, outlet openings directed to the side and to the front can be formed in a simple manner.
- a mixing chamber is formed, in which the outer water supply and the inner water supply are brought together.
- a uniform or at least comparable jet pattern can thus be achieved for both water channels.
- the mixing chamber is delimited by a common outlet structure for the at least two water channels. In this way, a common, identical or at least comparable jet formation can be achieved for the at least two water channels.
- a baffle plate is arranged downstream of the flow obstacle. This means that the water can be calmed down.
- the forwardly directed outlet openings are directed towards the baffle plate. It is thus possible to prevent the forward flow from exiting the insert part unhindered.
- the mixing chamber has at least one ventilation window. This can allow intake air to enter in order to enrich a jet of water with air bubbles.
- at least one acceleration nozzle is formed in the outer water supply at the entrance to the mixing chamber. An aerated jet can thus be generated in the outer water supply.
- a screen is formed, which surrounds and/or borders the flow obstacle.
- jet formation of the exiting water can be achieved.
- the panel covers the ventilation windows for the sideways flow. It is thus possible to prevent the laterally directed flow from escaping from the at least one ventilation window.
- a grid insert is arranged in the mixing chamber. Mixing can thus be improved.
- the grid insert has a central hole that is larger than a dimension of an opening of the inner water supply into the mixing chamber. This avoids the flow of the inner water supply being directed directly onto the grid insert. This can be advantageous, for example, if cooking water is carried in the inner water supply. Another advantage here is that recombination of the jet inside can be reduced, so that special jet shapes can be realized.
- a grid insert is arranged in the mixing chamber. Thorough mixing in the mixing chamber can thus be supported. It can be provided here that the baffle plate is formed on a grid insert, in particular on the grid insert already mentioned. A simple provision of a baffle plate is thus described. Additional parts for arranging or fastening the baffle plate are not necessary, assembly steps can be avoided.
- a sleeve which forms the inner water supply
- a splitter unit which forms at least one, in particular the at least one already described, acceleration nozzle in the outer water supply.
- the inner water supply forms a sleeve at its entrance for plugging in a connecting line.
- a connecting line can be attached without pipe clamps or without an additional connecting element.
- the sleeve and the flow obstacle are connected in one piece.
- a simple manufacture can be achieved, and the flow obstacle can be kept safe and sealed. It can even be provided that the sleeve is integrally connected to the cuff.
- the advantage here is that leakage flows into the outer channel can be avoided. Undesirable heating of the fitting during operation can thus be avoided or at least reduced.
- An advantageous application of the invention relates to the use of an internal water supply of a sanitary insert according to the invention, in particular as described above and/or according to one of the references to a sanitary insert directed claims , for the passage of cooking water or treated water .
- other treated waters are also possible.
- gases such as carbonic acid, provided with flavorings and colorings such as lemonade, juices, ....
- the advantage here is that outgassing can be delayed.
- the insert according to the invention can therefore be used universally.
- the external water supply can be used to conduct mixed water.
- Figure 1 shows a sanitary insert according to the invention in a three-dimensional oblique view of an inflow side
- FIG. 2 shows the sanitary insert from FIG. 1 in an axial section
- FIG. 3 shows the sanitary insert from FIG. 1 in a top view of the inflow side to show a position of the sectional plane in FIG. 2,
- FIG. 4 shows the sanitary insert from FIG. 1 in an axially sectioned, three-dimensional oblique view
- FIG. 5 shows an axial section through part of a sanitary fitting to explain the position of use of the sanitary insert according to FIG. 1,
- FIG. 6 shows the sanitary insert from FIG. 1 in a three-dimensional exploded view with a view of the inflow side and
- FIG. 7 shows the sanitary insert from FIG. 1 in a three-dimensional exploded view with a view of the outflow side.
- FIGS. 1 to 7 are described together below.
- a sanitary insert designated as a whole with 1 is designed as a jet shaper and/or jet regulator 2 and is used for the position of use shown in FIG.
- FIG. 1 shows an example of a fastening of the sanitary insert 1 with a mouthpiece 44 which is fastened to the outlet pipe 3 by means of a screw connection 43 .
- a seal 42 seals to the outside.
- An inflow side 5 and an outflow side 6 of the sanitary insert 1 are connected by two water ducts 7 , 8 which are separated from one another in sections and connected parallel to one another.
- the water from both water channels 7 , 8 thus exits from the outlet 9 of the sanitary fitting 4 .
- an outer water channel 7 is designed in such a way that it surrounds or surrounds the second, inner water channel 8 includes .
- Each of the water channels 7 , 8 thus forms a channel.
- the water flows along an outer flow path 39 , in the inner water channel 8 along an inner flow path 38 .
- the outer water line 7 is fed from an outer water line 36 in the outlet pipe 3
- the inner water line 8 is fed from an inner water line 37 .
- the water lines 36, 37 run separately from one another to assigned valves (not shown).
- a flow obstacle 10 is arranged in the inner water channel 8 , which represents an additional flow resistance for the flowing water.
- This flow obstacle 10 is designed in such a way that a sideways flow 11 is generated, through which the water flow of the inner water flow 8 widens.
- the flow 11 is a radial flow, but in other exemplary embodiments flows are generated in other laterally directed directions oriented transversely to the longitudinal axis.
- the flow obstacle 10 results in a back pressure on the inflow side 5 , which leads to a reduced pressure drop in the outlet pipe 3 . This can prevent steam bubbles from forming in the outlet pipe 3 when the superheated water expands. This overheating can be achieved that the exiting cooking water at the outlet 9 close to 100°C.
- the flow obstacle 10 is cup-shaped and has outlet openings 15 directed sideways in its cup wall 14. These outlet openings 15 deflect part of the liquid in the inner water channel 8 in a radial or lateral direction.
- the flow obstacle 10 also has forward-facing outlet openings 17 in its pot bottom 16, which are axial in this case.
- the inner flow path 38 is thus divided into a sideways (here radial) directed flow 11 and a forward (here axial) directed flow 40.
- a mixing chamber 18 is formed downstream of the flow obstacle 10, into which both water channels 7, 8 open.
- the mixing chamber has a greater clear width (measured transversely to the longitudinal axis 12) than the inner water channel 8.
- An outlet structure 19 delimits the mixing chamber 18 on the outside and in particular on the outflow side 6.
- a baffle plate 20 is formed below the flow obstacle 10 and the flow is directed against it through the outlet openings 17 directed forward.
- the mixing chamber 18 further has at least one ventilation window 21 through which air can be sucked into the mixing chamber 18 . This results in an aerated jet of water containing air bubbles.
- the ventilation windows 21 are formed on the pot-shaped lower part 45 of the sanitary insert 1 .
- the perforated plate 23 is part of a dismantling unit 30 which is snapped or clipped to the lower part 45 .
- This screen 24 has a dimension along the longitudinal axis by which the ventilation windows 21 for the sideways flow 11 are covered.
- At least one grid insert 25 , 41 is arranged in the mixing chamber 18 , which divides the jets in the water ducts 7 , 8 and thus leads to improved mixing of the air with the water.
- the grid insert 25 has a central hole 26 which avoids an area of direct flow through the inner water channel 8 .
- the dimension 27 of a mouth 28 of the inner water channel 8 is smaller than a dimension of the central hole 26 .
- the baffle plate 20 already mentioned is designed in one piece with the second grid insert 41 .
- the inner water guide 8 On the inflow side, the inner water guide 8 has a sleeve 29 which is clipped into a splitter unit 30 , here a perforated plate 23 .
- the plate-shaped dismantling unit 30 is clamped between a stop 31 and a latching projection 32 .
- the sanitary insert 1 in the inner water supply 8 has a cuff 33 into which the Connecting line 34 or a connecting pipe is inserted.
- the connection line 34 or the connection pipe can in this case carry a sealing ring 35 which seals against the cuff 33 .
- the cuff can also be integrally connected to the dismantling unit 30 . Separation or combination depends on the proportions and manufacturing process used.
- boiling water flows in the inner water supply 8, which can be heated to over 100° C. by a high operating pressure in the inner water supply 8 without evaporating.
- Mixed water flows out of a mixing cartridge (not shown) in the outer water channel 7 .
