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.
- Another disadvantage of the commercially available low-pressure jet is that they often react sensitively to an intake-side inflow deviating from the axial symmetry, as is often the case in handheld showerheads or cast fittings, for example. The result is a poor and splashing, inhomogeneous spray pattern.
- 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 flow holes of this hole structure have a small flow cross-section 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 re-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 can 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 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 m of the hole structure, so that the hole structure, which may also be designed as a sieve surface, surrounds the central by-pass in an annular manner.
- 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 radially.
- 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 In order that the closing body flowed around by the flowing water does not generate any undesirable turbulence and forms no unnecessary flow resistance in the water, it is advantageous if the closing body is of spherical, spherical segment or mushroom shape and has a partial region tapering in the direction of flow.
- a preferred embodiment according to the invention provides that the closing body is formed at least partially spherical segment-shaped, 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 to 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, the is guided displaceably in a guide sleeve held stationary in the water outlet.
- 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 mxt exnem round outer cross-section is slidably guided.
- 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 offers advantages with regard to a better jet pattern, especially in the case of oblique flow can.
- the water outlet according to the invention can reliably reduce an undesirably high pressure, and that this reliable function of the water outlet according to the invention is not impaired by incorrect operations, for example by closing the water outlet by means of the palm, the fingertips or a plane surface, it is advantageous if the outflow-side peripheral edge region of the cartridge housing is formed by circling and Emformungen approximately crown-shaped.
- FIG. 1 shows a water outlet configured as an insertion cartridge and shown in a longitudinal section, which has an inflow-side perforated structure with a central bypass.
- this water outlet is designed as a no-load protection, which should prevent emptying of the remaining in a sanitary low-pressure fitting after closing the valve water column,
- FIG. 2 shows the water outlet from FIG. 1 in a plan view of the inflow-side hole structure, the By-pass being in its open position, as in FIG. 1, FIG.
- FIG. 4 shows the water outlet from FIGS. 1 to 3 in a plan view of the inflow-side hole structure, the central by-pass with its by-pass valve being in its closed position, FIG.
- Fig. 5 shows the water outlet of Fig. 1 to 4 in a perspective plan view on the inflow side
- FIGS. 1 to 5 shows the water outlet from FIGS. 1 to 5 in a perspective view of its outflow side.
- a water outlet 1 is shown, the emptying of the in a low-pressure fitting, the Finally, to a pressureless water tank is intended to prevent after closing the remaining water column in the valve.
- This water outlet 1 is embodied here as an insertable cartridge which can be mounted at the outlet end of the outlet fitting by means of a conventional outlet nozzle, which is not further illustrated.
- the insert cartridge shown here and used as an idle 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. A change in volume takes place in the hot water tank, with the volume of water expanding in the event of heating of the water.
- the water column remaining in the outlet fitting may also change.
- the water outlet 1 shown here has a hole structure 2 that is permeable to air and a surface tension generating voltage.
- the flow holes 3 of this hole structure 2 have a small flow cross-section in order to produce a surface tension that is sufficient to ensure that after closing the outlet valve To keep the outlet valve remaining water column in the outlet fitting and to counteract a Nachfphi and emptying of 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 flow holes 3 in cross-section, which opposes the flow of water as low as possible flow resistance.
- the by-pass 4 is arranged coaxially to the longitudinal central axis and the valve opening 6 of the by-pass valve 5 is delimited by the inner circumferential edge of the annular peripheral hole structure 2.
- the closing body 7 of the central by-pass valve 5 is provided, which is movably guided along the narrow edges 8 of the flow guide walls 9 surrounding the closing body 7 in a radiating manner, preferably evenly spaced circumferentially and radially arranged.
- 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 closes its valve opening 6 with the base area 12 of its spherical segment-shaped partial area 10 in the closed position of the by-pass valve 5, the spherical segment-shaped partial area 10 extends with its spherical circumference up to the individual jets produced by the throughflow holes 3 of the hole structure 2. 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 through-flow holes 3 of the hole structure 2.
- the flow holes 3 of the hole structure 2 are delimited by flow guide walls 14, wherein the flow holes 3 have a flow length which is at most equal in size to their clear flow cross section. Since the flow guide walls 14 delimiting the throughflow holes 3 can thus well guide the individual beams which have taken place in the hole structure 2, even in the event of an oblique incident flow, a homoge- neous flow is achieved. gene 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 reliably reduce an undesirably high pressure and thus this safe function of the water outlet 1 is not impaired by incorrect operation, for example by closing the water outlet 1 by means of the palm, by means of the fingertips or with the aid of a plane surface, this is outflow-side peripheral edge region of the cartridge housing by formations 15 and recesses 16 is approximately crown-shaped.
- the length of the guide pin 11 is dimensioned so that even when the downstream end face of the guide pin is flush with the guide sleeve 13, the by-pass valve 5 is not yet in its closed position shown in Fig. 3.
