Definitions

  • the invention relates to a jet regulator which is designed for the outlet of a water tap and/or a machine for preparing drinks.
  • the invention relates to a jet regulator through which carbonated water is also dispensed.
  • the invention further relates to a water tap, water dispenser or machine for preparing drinks provided with the jet regulator according to the invention.
  • So-called jet regulators are attachments that form the so-called “point of use”, i.e. the water outlet, on a faucet or a water dispenser, for example.
  • the water outlet should emit as even a jet as possible, with as little splashing as possible when it hits a container or sink underneath the outlet.
  • Such jet regulators often also serve to save water and include a throttling device.
  • So-called aerators are well known in practice and are used as jet regulators on most household fittings.
  • the sieve discs homogenize the water jet and the water mixes with air through the air gap, so that, among other things, the mass of the jet in relation to its diameter decreases.
  • Such measures can reduce the tendency of the jet to splash when it hits a surface.
  • a water outlet from which carbonated water is dispensed is more likely to drip, as any residual amounts in the connector are pushed out by the carbon dioxide.
  • Jet regulators are from the documents DE 200 22 1 66 U1 , DE 20 2015 007873 U1 and US 2017/152651 A1 known.
  • the invention is therefore based on the object of providing a jet regulator in which the aforementioned disadvantages of the prior art are at least reduced.
  • the invention relates to a jet regulator for the outlet of a faucet or drinks dispenser.
  • the invention relates to a jet regulator which is used for a beverage dispenser, in particular a water dispenser, through which carbonated water can also be dispensed.
  • the invention generally relates to a jet regulator which can also be used for all types of fittings.
  • the jet regulator can be provided with a standard internal or external thread (e.g. M16-M24) and can be used instead of a conventional aerator, which is designed to enrich the jet with air.
  • the jet regulator comprises an outer sleeve and an insert that sits in the sleeve.
  • the insert is aligned coaxially to the sleeve.
  • annular channel in the sense of the invention is also understood to mean an outlet which is only partially designed as a ring, i.e. in particular a ring segment, or which is divided into ring segments.
  • the outlet is an uninterrupted ring channel, i.e. a ring channel through which no webs run.
  • an expansion chamber is arranged between an inlet of the jet regulator and the ring channel, which extends around the insert.
  • the expansion chamber can in particular be ring-shaped.
  • an expansion chamber is understood to mean a region in the flow path in which the total cross-section of the flow path between the inlet and outlet of the jet regulator increases compared to a previous section, in particular in the inlet region.
  • the expansion chamber is arranged in particular between a channel arranged at the inlet with a smaller overall cross-section, which can also be understood as the inlet for the expansion chamber, and the outlet.
  • Expansion chambers are usually used to influence the flow behavior of gases, which, unlike water, are compressible.
  • the liquid in contrast to a gas and at least when no carbonated water is used, the liquid cannot increase in volume to a significant extent.
  • the pressure within the expansion chamber up to the outlet can be kept very low, in particular reduced to almost atmospheric pressure, since the water is accelerated in the area of the inlet before being introduced into the expansion chamber due to the small cross-section of an inlet to the expansion chamber.
  • the inlet to the expansion chamber therefore has a smaller cross-section than a water inlet of the jet regulator (e.g. a screw connection), as well as a smaller cross-section than the expansion chamber.
  • a water inlet of the jet regulator e.g. a screw connection
  • the jet regulator according to the invention can in particular be designed such that at an applied line pressure of 5 bar the pressure within the expansion chamber is less than 1.5 bar (under standard conditions and 20 °C water temperature).
  • the arrangement of the expansion chamber around the insert also ensures a compact design.
  • the jet regulator can be provided as an essentially circular-cylindrical sleeve. In terms of its dimensions, this cannot differ significantly from a conventional aerator.
  • the ratio of diameter to height of the sleeve can be greater than 1. Due to the smaller cross-section on the flow side in front of the expansion chamber, the water is fed into the expansion chamber at a high speed depending on the applied line pressure.
  • the flow slows down into a turbulent flow. Due to the low pressure, the turbulent flow can be easily converted into a laminar flow on the outlet side, namely by using an inner sleeve with a conical collar that extends around a conical head piece of the insert.
  • the insert is designed to be conical.
  • the insert is designed as a flow throttle.
  • the minimum cross-section of the jet regulator is therefore reduced compared to the cross-section of the connection piece to the water pipe for which the jet regulator is used.
  • the inlet leads through a central channel which leads into an annular channel which runs counter to the flow direction and extends upwards between the central channel and the insert.
  • the insert is therefore pot-shaped with a blind hole into which the central channel protrudes and thus forms a flow reversal in cooperation with the insert.
  • the water is thus led to the bottom of the insert, then guided upwards, in particular via an annular channel, and then enters the expansion chamber arranged around it.
  • This embodiment of the invention is particularly advantageous for the dispensing of carbonated water.
  • the water is fed into the expansion chamber through a side inlet, in particular through an annular channel, or from above.
  • a side inlet in particular through an annular channel, or from above.
  • dripping is usually also prevented by a negative pressure that develops in the fitting.
  • the embodiment in which water is fed into the expansion chamber through the side inlet is particularly suitable for such a fitting.
  • the inlet piece can in particular comprise a plate which forms a gap, in particular an annular gap adjacent to the inner wall of the sleeve.
  • the annular gap can in particular be formed by a plurality of inlet openings distributed around the circumference.
  • This plate especially if it is structured, in particular if it has webs, can be used to homogenize the pressure distribution of the water flowing into the jet regulator.
  • the cross-sectional area between a region with a minimum cross-section at or after the inlet increases compared to a region of the expansion chamber with a maximum cross-section preferably by at least 2 times, particularly preferably by at least 5 times and/or less than 100 times, particularly preferably less than 50 times.
  • the outlet comprises a ring with axially extending spacers for the insert.
  • the spacers can in particular be designed as webs distributed around the circumference of a collar, in particular a conical collar.
  • the jet regulator comprises an outer sleeve, an inner sleeve, the insert and an inlet piece, whereby these components are captured in the outer sleeve and positioned relative to one another by spacers integrated into the corresponding components.
  • the area up to the outlet is reduced to a minimum cross-sectional area, which can in particular be 0.1 to 0.8 times the maximum cross-sectional area in the area of the expansion chamber.
  • This reduction in cross-section is achieved by reducing the diameter of an annular channel between the sleeve and the insert, which initially forms the expansion chamber, by the insert having a conical head piece, which is opposed by a conically inclined collar of the sleeve, which forms the front face of the sleeve.
  • the sleeve may have an outer diameter of 10 to 40 mm, preferably 15 to 25 mm.
  • jet regulator can also be provided for applications, particularly in the industrial sector.
  • the jet regulator comprises a UV light source.
  • This can be arranged, for example, in the inlet piece and serves to disinfect the jet regulator or the residual water adhering to the jet regulator.
  • the jet regulator according to the invention is superior to aerators in terms of hygiene, since the total surface area is significantly smaller than that of aerators with, for example, honeycomb or grid-shaped sieve surfaces.
  • the jet regulator can be dimensioned such that, at a pressure of 6 bar at the inlet, the Reynolds number Re of the outgoing water is below 2,300, preferably below 2,000, both at 20 °C warm water, 20 °C warm water with 6 g/l carbon dioxide and at 60 °C warm water (and otherwise under standard conditions).
  • a jet regulator could be provided which is equally suitable for warm water, especially water used for making tea and which can be 80 °C or more, and which can also be used for carbonated water.
  • the jet regulator according to the invention can be used, for example, for water dispensers, machines for preparing beverages, in particular for preparing hot and cold beverages.
  • the invention further relates to a faucet, a water dispenser and a machine for preparing beverages, which includes the jet regulator described above.
  • This is preferably connected to a water outlet on the fitting or machine side via a threaded connection.
  • Fig.1 shows in a perspective view an embodiment of a jet regulator 1, which is connected to a water connection 2.
  • the water connection 2 can, for example, be part of a water dispenser or a machine for preparing drinks or the end piece of a water tap.
  • Such outlets are usually tubular and emit a turbulent, inhomogeneous water jet, which, among other things, has a strong tendency to splash when it hits an adjacent surface.
  • the task of the jet regulator 1 is to convert the escaping water into a visually appealing jet that is as circular and cylindrical as possible and which has only a slight tendency to splash when it hits a surface.
  • the aim of the jet regulator 1 can be to reduce the flow rate when the tap is turned on via a throttle and thus contribute to saving water.
  • the jet regulator 1 For attachment to the water connection 2, in this embodiment the jet regulator 1 comprises an upper part 60 which is designed as a handle with which the jet regulator 1 can be easily attached.
  • the jet regulator 1 is completely, essentially circular-cylindrical and thus serves in particular to replace conventional aerators on a water tap.
  • the jet regulator 1 has a sleeve-shaped outer contour.
  • the sleeve comprises an outer sleeve 10 and an inner sleeve 20.
  • a homogeneous water jet which has a laminar flow, leaves the jet regulator 1 via an annular channel 3.
  • the annular channel 3 is formed between a coaxially arranged insert 30 with a conical head piece and a collar 21 which forms the front end wall of the inner sleeve 20.
  • the collar 21 extends conically forwards, at least on the inside, preferably substantially parallel to the opposite wall of the insert 30 which is conically formed at the front.
  • the ring channel 3 the end of which forms the outlet, is designed to taper conically towards the front.
  • the total cross-section of the annular channel 3 decreases towards the front, which contributes to the generation of a laminar flow.
  • Fig. 2 is a longitudinal section of the jet regulator 1 including water connection 2. This illustration shows all components of the jet regulator 1.
  • the jet regulator 1 is connected to the water connection 2 by means of the upper part 60.
  • the water enters an expansion chamber 6 via two flow paths.
  • the jet regulator is designed such that the water enters the expansion chamber 6 via only one of the flow paths shown.
  • Seal 4 is located between water connection 2 and upper part 60.
  • an inlet piece 40 is arranged, which serves to guide the water into the expansion chamber 6.
  • the upper part 60 and the inlet piece 40 can also be designed as a single component.
  • the water flows through the inlet 7 through the jet regulator 1, which is designed as a sleeve, and leaves the jet regulator 1 at the outlet 3.
  • the sleeve comprises an outer sleeve 10 and an inner sleeve 20.
  • the outer sleeve 10 is connected to the upper part 60 via a thread 12.
  • the components of the jet regulator 1 for jet shaping are arranged one after the other between the upper part 60 and a front collar 11 of the outer sleeve 10.
  • the inner sleeve 20 rests with its front side on the collar 11 of the outer sleeve 10. Preferably, all of these components are inserted into the outer sleeve 10 without having to be welded or glued together.
  • the outer sleeve 10 can be made of metal or plastic.
  • the other components of the jet regulator 1, in particular the insert 30 and the inlet piece 40, are preferably designed as plastic injection-molded parts.
  • the water flowing in from the inlet 7 is guided into the expansion chamber 6 via the inlet piece 40, whereby, particularly depending on the embodiment, two flow paths are possible, which, however, can also be combined with one another, as shown here.
  • the expansion chamber 6 is designed as an annular channel which is arranged between the coaxial insert 30 and the sleeve, more precisely the inner sleeve 20.
  • incoming water can enter the expansion chamber 6 via a side inlet 8.
  • the inlet piece 40 can be designed with one or more edge-side openings so that water can flow into the expansion chamber 6 via a lateral inlet 8, which has a plurality of openings distributed around the circumference.
  • This flow pattern is particularly suitable if no carbonated water is to be dispensed.
  • the inlet piece 40 comprises a central channel 41, which is preferably aligned coaxially.
  • the insert 30 is cup-shaped and comprises a blind hole 30 inside into which the central channel 41 leads.
  • the central channel 41 projects into the blind hole 31, so that the interaction of the central channel 41 and the blind hole 31 creates a flow reversal which leads into the channel 5.
  • the expansion chamber 6 is ring-shaped.
  • the annular channel of the expansion chamber 6 then merges into a section up to the outlet 3 in which, due to the conical design of the insert 30 and the collar 21 which also runs conically towards the front, the diameter and thus also the total cross-sectional area of the annular channel gradually decreases up to the outlet 3.
  • inlet 7 and outlet 3 there are no openings along the sleeve of the jet regulator 3 through which air can enter the water flow.
  • the jet regulator 1 Due to the absence of grid-shaped inserts, the components of the jet regulator 1 have a relatively small surface area, which reduces undesirable germ formation.
  • the jet regulator 1 is also suitable for dispensing hot water, cold water and carbonated water.
  • the jet regulator 1 can be designed with a UV light source for killing germs.
  • components of the jet regulator in particular the insert 30, the inner sleeve 20 and/or the inlet piece 40 can be made of a UV-permeable material, in particular of a UV-permeable plastic.
  • the central channel 41 is provided on its upper side with a ring 50 which serves as a spacer.
  • Fig.3 is a perspective view of the outer sleeve 10.
  • the outer sleeve 10 comprises on its underside the collar 11, which serves as a stop for the inner sleeve (20).
  • Fig.5 is a perspective view of the inner sleeve 20, seen from the flow direction, i.e. from behind.
  • the inner sleeve 20 is pot-shaped with a central opening in the bottom. Accordingly, the inner sleeve 20 comprises a front-side collar 21.
  • the collar 21 On the inside, i.e. in the direction of the insert, the collar 21 comprises a plurality of spacers 22 which are distributed around the circumference of the collar and on which the insert (30) sits in the assembled state.
  • the spacers 22 are designed as axially extending webs. This can improve the formation of a laminar flow.
  • Fig.6 is a perspective view of the opposite side of the inner sleeve 20.
  • the side wall of the inner sleeve 20 tapers obliquely, i.e. conically towards the front, in particular at an angle of 2 to 8° to the central axis.
  • This design contributes to a successive slight reduction in the diameter of the expansion chamber towards the outlet, which improves the formation of a laminar flow.
  • axially extending webs 23 are provided on the side wall.
  • the webs 23 merge into the conical collar 21 via a transition web 24 at the front.
  • This design has the function of a visually attractive technical appearance.
  • an internal conical design of the collar 21 is sufficient for flow guidance, so that the area between the transition webs 24 can also be filled with material in another embodiment (not shown).
  • Fig.7 is a perspective view of the insert 30, seen from behind, i.e. from the direction of the flow.
  • the insert 30 comprises the blind hole 31 which is tapered at the front.
  • the webs 33 are distributed around the circumference in the axial direction and serve to connect to the inlet piece.
  • Fig.8 is a perspective view of the insert 30 from the side.
  • the insert 30 is conical at the front and begins with a rounded head piece 34.
  • the side wall of the insert 30 preferably extends at an angle of 30 to 60°, particularly preferably 40 to 50°, to the central axis.
  • the transition region 35 is not exactly frustoconical, but comprises a recess 37 within which the angle of the side wall relative to the central axis changes.
  • the angle of the side wall therefore becomes steeper towards the outlet, which improves the formation of a laminar flow.
  • the transition area 35 merges into a fuselage section 36 via a rounded area 38.
  • the fuselage piece 36 is slightly conical, in particular the side wall of the fuselage piece 36 is at an angle of 3 to 15° to the central axis.
  • the conicity of the side wall of the body piece 36 can correspond to the inclination of the side wall of the inner sleeve in this area.
  • Fig.9 is a perspective view of the inlet piece 40.
  • the inlet piece 40 comprises a central channel 41 which opens into the insert (30).
  • the inlet piece 40 is disk-shaped and includes the ring disk 42, which has channels 44 on the edge, through which part of the water can also reach the expansion chamber directly from the edge, without flowing over the insert. If this is not desired, the channels 44 can also be omitted (not shown).
  • the annular disc 42 can be structured.
  • a structure is provided by star-shaped webs 43.
  • Fig.10 is a further perspective view of the inlet piece 40.
