Definitions

  • the invention relates to a water outlet for a sanitary low-pressure outlet fitting.
  • Hot water tanks are already known, which are mounted under a vanity unit as part of a decentralized hot water supply. Such hot water tanks are designed as heated pressureless containers, the filling volume can contract or expand depending on the water temperature. There is a change in volume of the water in the container, wherein the volume of water expands in the event of heating of the water.
  • the jet regulators usually provided at the outlet end of a sanitary outlet fitting have comparatively small holes, for example in the area of their jet separators, which can close due to contamination in the water and close the outlet fitting in such dangerously tight conditions that a dangerous pressure can build up in the water tank.
  • Low pressure fittings therefore usually do not use normal jet regulators. Rather, there jet regulators are used, which have much larger flow cross-sections.
  • it is a particular disadvantage that in the case of temperature-induced expansions and contractions in the water tank and the water column in the valve can change.
  • a water outlet nozzle with a reversible jet regulator insert comprising a cleaning jet channel and at least one flow chamber having a plurality of water outlet nozzles, wherein at least one inflow opening of the Strömunshunt is controlled with at least one biased in its closed position valve, such that the inflowing water from the valve of a specifiable back pressure of the water is openable.
  • valve of the jet regulator insert provided in the known water outlet mouthpiece has a valve piston axially displaceable in the water flow direction Valve plate and at least one water inlet. opening, which leads to the running through the hollow valve piston cleaning jet channel.
  • the one in the DE 38 17 270 A1 previously known jet regulator intended use is in a normal operating position so within the Dürchlassqueriteses that it is completely flowed through by the liquid flow, while the jet regulator insert is released in response to the triggering device and then fall out in the outflow to the passageway subsequently completely free until the jet regulator is replaced or serviced.
  • the water outlet according to the invention has a water permeable to the water outlet direction and a pressureless state due to the surface tension water-retaining hole structure.
  • the through-holes of this hole structure have a small flow area in order to produce a surface tension sufficient to maintain the water column remaining in the outlet fitting after closing the outlet valve of the outlet fitting and to counteract the flow and run-off of that water column. If the water container increasingly contracts with the cooling of the heated water, suction of air and pressure compensation can nevertheless take place via the perforated structure.
  • the by-pass and its at least one by-pass valve is effective, which moves due to this pressure increase from its closed position against a restoring force in its open position and is able to cause a pressure reduction.
  • the water outlet according to the invention can be permanently installed in a sanitary outlet fitting.
  • the water outlet according to the invention in order to use the water outlet according to the invention in a variety of outlet fittings in a simple manner advantageous, it is advantageous if the water outlet is designed as an insertable into the outlet end of a sanitary outlet fitting insert cartridge.
  • the hole structure is designed as a preferably honeycomb-shaped sieve surface.
  • a preferred embodiment according to the invention provides that the By-pass is arranged centrally in the hole structure, so that the possibly also formed as a screen surface hole structure surrounds the central By-pass annular.
  • the by-pass valve has a closing body which is movably guided along the narrow edge sides of the flow guide walls, which preferably surround the closing body in a radiating manner.
  • the closing body of the by-pass valve can be movably guided along the narrow edges of the flow guide walls radially surrounding the closing bodies.
  • the closing body is designed spherical, spherical segment or mushroom-shaped, and has a tapered in the flow direction portion.
  • a preferred embodiment according to the invention provides that the closing body is formed at least partially spherical segment, that the closing body with the base of its spherical segment form in the closed position of the by-pass valve closes the valve opening, and that the closing body with its spherical portion up to the Single rays generated by the flow holes of the hole structure ranges.
  • This embodiment is characterized by a low-resistance and homogeneous beam guidance and shaping.
  • the closing body has a preferably downstream arranged guide pin, in a in the water outlet fixedly held guide sleeve is guided displaceably.
  • guide pin and guide sleeve are guided comparatively low friction along narrow lines of contact when the guide sleeve has a polygonal and preferably hexagonal clear guide cross-section, in which the guide pin is guided displaceably with a round outer cross-section.
  • the closing body In order to move the closing body as smoothly as possible against a consistently constant restoring force, it is advantageous if the closing body is movable against the restoring force of at least one return spring.
  • the formation of a homogeneous total jet in the water outlet according to the invention is favored when the flow holes are bounded by flow guide walls.
  • flow guide walls In order for these flow guide walls to be able to fulfill their jet-guiding function particularly effectively and well, it is advantageous if the flow holes have a smaller or at most equal flow length compared to their clear flow cross-section, which can offer advantages in terms of a better jet pattern, especially in the case of oblique flow.
  • the water outlet according to the invention can reliably reduce an undesirably high pressure, and thus this safe function of the water outlet according to the invention is not impaired by incorrect operation, for example by closing the water outlet by means of the palm, the fingertips or a plane surface, it is advantageous if the Einsetzpatrone has a cartridge housing, and when the downstream peripheral edge portion of the cartridge housing is formed by circling and recesses approximately crown-shaped.
  • a water outlet 1 is shown, which is the emptying of the in a low-pressure fitting, the connection is intended to a non-pressurized water tank to prevent after closing the remaining water column in the valve.
  • This water outlet 1 is designed here as Einsetzpatrone, which can be mounted with the help of a non-illustrated, conventional outlet nozzle at the outlet end of the outlet fitting.
  • the insert cartridge shown here and serving as an open circuit fuse is needed, for example, in hot water tanks, which are mounted as part of a decentralized hot water supply under a vanity.
  • hot water tanks are designed as heated pressureless containers, the filling volume can contract or expand depending on the water temperature. In this case, a change in volume takes place in the hot water tank, wherein the water volume expands in the event of heating of the water.
  • the water outlet 1 shown here has an air-permeable and surface tension-generating hole structure 2 opposite to the water outlet direction.
  • the flow holes 3 of this hole structure 2 have a small flow area in order to produce a surface tension sufficient to close the outlet valve in the outlet fitting To keep remaining water column in the outlet fitting and to counteract a Nachfphi and emptying this water column. If the water column connected to the hot water tank draws increasingly together with the cooling of the heated water in the outlet fitting, it is still possible for air to be drawn in via the hole structure 2 Pressure equalization done.
  • the hole structure 2 is formed as a honeycomb-shaped screen surface with hexagonal in cross-section flow holes 3, which opposes the flow of water as low as possible flow resistance.
  • the by-pass 4 is arranged coaxially to the longitudinal center axis and the valve opening 6 of the by-pass valve 5 from the inner peripheral edge of the annular peripheral hole structure 2 bounded.
  • the closing body 7 of the central by-pass valve 5 is provided, which along the narrow edges 8 of the closing body 7 radially surrounding, preferably circumferentially uniformly spaced and radially arranged flow guide walls 9 is movably guided.
  • These flow guide walls 9 not only form a secure sliding guide around the closing body 7, but can also form the water emerging from the water outlet 1 to a homogeneous overall jet.
  • the closing body 7 is approximately mushroom-shaped and has on the inflow side a spherical segment-shaped portion 10, formed on the downstream side of a cylindrical guide pin 11 is. While the closing body 7 with the base 12 of its spherical segment-shaped portion 10 in the closed position of the by-pass valve 5 closes the valve opening 6, the spherical segment portion 10 extends with its spherical circumference up to the through holes 3 of the hole structure 2 generated individual beams. The lapped by the flowing water flow closing body 7 thereby favors a low-resistance and homogeneous beam guidance and shaping in the water outlet. 1
  • the formed on the closing body 7 guide pin 11 is guided in a guide sleeve 13 slidably.
  • This guide sleeve 13 is arranged coaxially with the longitudinal center axis of the water outlet 1 designed as an insert cartridge and connected in one piece with the narrow edges 8 of the flow guide walls 9 drawn inwards on the outflow side. Since the cylindrical guide pin 11 has a round outer cross section and, in contrast, since the guide sleeve 13 has a polygonal and here hexagonal clear guide cross section, guide pin 11 and guide sleeve 13 are performed comparatively low friction along narrow lines of contact.
  • the valve opening 6 of the by-pass valve 5 has a substantially larger opening cross section compared to one of the throughflow holes 3 of the hole structure 2.
  • the flow holes 3 of the hole structure 2 are bounded by flow guide walls 14, wherein the flow holes 3 have a comparison with their clear flow cross-section at most equal flow length. Since the flow-through walls 14 delimiting the through-flow holes 3 can thus well guide the individual jets made in the hole structure 2 even in the event of an oblique flow, a homogeneous flow is achieved Beam guidance in the water outlet 1 additionally favored.
  • the axially spaced from the hole structure 2 plane face 90 of the flow guide walls 9 serves as an additional partial baffle and contributes to the beam shaping.
  • the flow guide walls 9 extend over the largest possible longitudinal region of the Einsetzpatrone to additionally contribute to an axially parallel alignment of the water jet after its exit from the water outlet and thus to its shapely appearance.
  • the water outlet 1 can safely reduce an undesirably high pressure and thus this safe function of the water outlet 1 is not affected by incorrect operation, for example by closing the water outlet 1 by the palm, with the help of fingertips or by means of a flat surface, is the downstream peripheral edge region of the cartridge housing by formations 15 and recesses 16 approximately crown-shaped.
  • the length of the guide pin 11 is dimensioned so that even if the downstream end face of the guide pin is flush with the guide sleeve 13, the by-pass valve 5 is not yet in his in Fig. 3 shown closed position.
