Definitions

  • the invention relates to a sanitary fixture according to the preamble of claim 1 or claim 2.
  • the invention is used in a sanitary built-in part, with a functional unit, and a diffuser formed downstream behind the functional unit, with the functional unit forming at least one inlet opening to a diffuser chamber, with the diffuser having a baffle plate delimiting the diffuser chamber in an inflow direction predetermined by the at least one inlet opening which deflects water flowing in through the at least one inlet opening in a lateral direction, the diffuser space being formed between the baffle plate and the functional unit and having an outlet opening through which water entering through the at least one inlet opening completely exits from the diffuser space.
  • a sanitary outlet element which can be inserted with its insert housing into the water outlet of a sanitary outlet fitting, and has an aerator for shaping the exiting water jet, which is preceded by a flow rate regulator or a flow restrictor on the inflow side, which regulates the amount of water flowing through per unit of time to a specified value
  • the value is regulated or limited, with the flow rate regulator or the flow restrictor being displaceably guided with the restrictor or regulator housing in the insert housing and being moved from an open position, in which the restrictor or regulator housing is flushed with at least a portion of the water, against the restoring force of at least one restoring element into a Closing position is movable, in which the aerator flowing water flows through the flow rate regulator or the flow restrictor.
  • a sanitary functional unit which has a housing which can be detachably fastened to the water outlet of a sanitary outlet fitting, the housing having an outflow-side housing end face with outflow openings.
  • a characteristic of the functional unit described is that the housing end face on the outflow side has at least one slot, the opposite long sides of which are designed as turning or tool engagement surfaces for a turning tool that can be detachably inserted into the at least one slot and is preferably designed as a coin.
  • a sanitary insert unit which has a flow rate regulator, which is followed on the outflow side by a low-pressure jet regulator, with the jet splitter of the described low-pressure jet regulator letting through a large amount of water even at the lowest pressures.
  • the object of the invention is to improve the jet pattern of an emerging water jet.
  • an opening cross-section of the outlet opening has an area that is 0.9 to 2 times, preferably 1 to 1.7 times, an area of an opening cross-section of the at least one inlet opening amounts to.
  • the surface areas are preferably chosen to be approximately or even exactly the same size. If there are two or more inlet openings arranged separately from one another, the total area of the two or more inlet openings for the described proportions are used.
  • the baffle plate is essentially (or even exactly) planar on a side facing the diffuser space. Undesirable turbulence, which could be generated by structures on the baffle plate, can thus be avoided.
  • the baffle plate is designed to be essentially (or even completely) free of obstacles on a side facing the diffuser space.
  • the invention has recognized that a jet splitting in the area of the baffle plate is not necessary for good subsequent ventilation.
  • the invention can easily achieve a substantially or completely trouble-free deflection of the flowing water after exiting the inlet opening.
  • the diffuser space has at least two inlet openings spaced apart from one another along a main flow direction, and that the diffuser space has a profile along the main flow direction that is between the spaced-apart inlet openings and/or defines a profile widening at the downstream of the at least two inlet openings.
  • the main flow direction can be described here as the preferably shortest connecting line between an inlet opening, preferably an inlet opening arranged furthest upstream, and the already mentioned outlet opening of the diffuser space. Due to the rectifying effect of the appropriately dimensioned diffuser space, this can coincide with the mean flow velocity direction in an angular segment containing the inlet opening.
  • the widening of the profile is preferably designed as a profile ramp. As a result, a step-free profile can be provided, so that the water in the diffuser space can flow with little or no turbulence.
  • the widening of the profile defines an enlargement of a cross-sectional area of the diffuser space transversely to the main flow direction, which is matched to a cross-sectional area of the downstream inlet opening. It can thus be achieved in a simple manner that the water entering via this downstream inlet opening can be combined with the water from the upstream inlet opening with as little turbulence as possible.
  • the continuity equation shows that the increase in cross-sectional area means that different speed profiles and/or sudden increases in speed can be avoided. Eddy formations can thus be reduced.
  • the baffle plate is delimited on all sides, ie circumferentially, by an enlarged cross section for the flowing water.
  • an obstacle-free delimitation of the impact plate can be achieved. It is particularly achievable that the flowing Water can thus flow off the baffle plate undisturbed.
  • the widening of the cross section is preferably formed by a (falling) step.
  • a turbulence desired after the baffle plate, through which air is added, can be easily achieved.
  • the at least one inlet opening is arranged opposite the baffle plate. A direct flow against the baffle plate can thus be achieved to deflect the direction of flow to the outside.
  • the at least one inlet opening is preferably oriented along a longitudinal direction of the sanitary installation part.
  • the at least one inlet opening is arranged in the center of the baffle plate. In this way, rotationally symmetrical flow conditions can be achieved. Twist formation can thus be avoided or at least reduced.
  • a carrier plate of the functional unit is supported on the baffle plate.
  • the support is preferably formed centrally on the baffle plate. This enables a symmetrical, in particular rotationally symmetrical, configuration of the diffuser space.
  • a flow divider which can serve as a filling element and thereby prevent undesired flow effects, is formed on the baffle plate in the center of the inlet opening.
  • a reference point can thus be formed, to which a flow in the diffuser chamber is aligned. Circular Flows or turbulence at a first impact point of the water on the baffle plate can thus be avoided.
  • the impinging jet naturally already has a cross-section of a (possibly deformed) circular disk, where water in each circular disk segment can simply be deflected outwards in a certain direction.
  • the flow divider can be formed by the support already mentioned. Thus, the structural design is easy to maintain.
  • the functional unit has at least one quantity regulator.
  • the advantage here is that a required or desired flow rate can be provided independently of the pressure within a working area. The flow conditions in the diffuser space are thus easy to control.
  • the functional unit can have at least one throttle. Flow rates in the diffuser chamber can thus be reduced compared to an unimpeded flow.
  • the functional unit has two quantity regulators connected in parallel in the direction of flow. Larger flow rates can thus be provided independently of the pressure.
  • the quantity regulators are preferably arranged concentrically to one another. This means that space can be saved without the control elements of the quantity regulator having to be dimensioned very small.
  • the two volume regulators can each form an entry opening into the diffuser space.
  • the inlet openings can be arranged spaced apart from one another along the aforementioned main flow direction, for example when the volume regulators are arranged concentrically with one another, and thus form an upstream and a downstream inlet opening.
  • a jet ventilation device is connected downstream of the diffuser.
  • An aerated jet can thus be provided.
  • the uniform or low-turbulence flow in the diffuser space according to the invention has proven to be particularly favorable for subsequent air enrichment.
  • the diffuser space has an essentially (or even exactly) constant height. Turbulence can thus also be avoided or at least reduced in the vertical direction (in relation to the baffle plate and/or an extension of the diffuser chamber).
  • the height of the diffuser space can be characterized, for example, as a dimension transverse to the direction of flow in the diffuser space and/or transverse to a direction of extent of the baffle plate.
  • the diffuser space forms a flow straightener. It is thus possible to achieve uniform, in each case, for example, radially aligned partial flows at the outlet opening, which are favorable for subsequent jet formation.
  • the diffuser space is preferably designed without obstacles or at least with few obstacles in order to avoid undesirable turbulence as much as possible.
  • the invention makes use of the fact that the flow straightening effect is generated in that the boundary walls of the diffuser space forming a channel are aligned and dimensioned in the manner described.
  • the height of the diffuser space is less than half the height of a downstream collection chamber.
  • a comparatively narrow diffuser space has proven to be favorable for the generation of a unidirectional flow.
  • the term "unidirectional" can also include flow patterns in which the partial flows are not parallel, but radially aligned with respect to a center.
  • the invention generally has the advantage that the most uniform possible flow pattern can be achieved in the diffuser space as a result of the narrow design.
  • the features described can be used individually or in combination with one another to generate a speed profile that is as homogeneous as possible. Large differences in the velocities of adjacent partial flows tend to create turbulence.
  • the invention provides measures to avoid the occurrence of large speed differences.
  • the invention proposes the features of the first independent claim.
  • the invention thus proposes a sanitary built-in part, in which an annular chamber is connected downstream of a diffuser in a direction of flow and opens into at least one outlet nozzle, with at least one ventilation opening being formed behind the at least one outlet nozzle, via which outside air can be supplied to generate an aerated water jet , proposes that the annular chamber above the at least one outlet nozzle in a longitudinal section has a contour into which an ellipse can be fitted, which has an aspect ratio of greater than 0.433 of a minor semi-axis to a major semi-axis.
  • annular chamber provides a space for inflowing water, which is approximately one in a longitudinal section enables a circular flow pattern and at the same time takes into account the cramped space conditions of a sanitary built-in part.
  • Such a flow pattern is particularly favorable for an effective admixture of air.
  • the fitting of an ellipse can be characterized, for example, in such a way that the preferably largest ellipse in terms of area is to be taken, which touches at four points on a contour or boundary line of a cross section transverse to the circulation chamber of the annular chamber, which is in particular approximated as a square.
  • the numerical ratio is preferably greater than or equal to 0.45, 0.5 or even 0.6. Thus even almost or exactly circular flow patterns can be achieved.
  • the invention proposes the features of the second independent claim as an alternative or in addition to the solution described above.
  • the invention thus proposes a sanitary built-in part, with an annular chamber downstream of a diffuser in a flow direction, which opens into at least one outlet nozzle, with at least one ventilation opening being formed on the outflow side of the at least one outlet nozzle, through which outside air is admitted can be fed to the generation of an aerated water jet, with a baffle between the diffuser and the annular chamber, which guides the inflowing water into the annular chamber, being formed, that the annular chamber in a partial annular chamber located above an extension of the baffle into the annular chamber in a Longitudinal section has a contour into which an ellipse can be fitted, which has an aspect ratio of greater than 0.52 of a semi-minor axis to a semi-major axis.
  • the invention has recognized that the water flows from the guide surface into the annular chamber, so that the described geometric cross-sectional shape is favorable
  • the aspect ratio is greater than 0.55 or equal to 0.55. More preferably, the aspect ratio is greater than 0.6 or equal to 0.6. Most preferably, the aspect ratio is greater than or equal to 0.69. This enables an even better approach to the circular track and thus even better ventilation.
  • the annular chamber has a square, in particular (substantially or even exactly) parallelogram-shaped, longitudinal section.
  • a cross-sectional shape in the form of a parallelogram can be implemented particularly easily and can provide sufficient space for good turbulence of the water with inflowing air.
  • the longitudinal section can thus be chosen to be transverse to a (for example circular) extension dimension of the annular chamber.
  • an enlarged annular chamber according to the invention can be achieved, for example, by forming a stepped constriction in front of the outlet nozzle.
  • the annular chamber can be formed with a maximum extension radially in relation to the longitudinal direction of the built-in part, without being limited by a cover lying above it and supported by it.
  • the functional unit is preferably formed on the cover.
  • the diffuser thus carries the functional unit.
  • the projections can be plate-shaped. This may improve turbulence by laterally deflecting water flow spanwise or along the annular chamber.
  • a plurality of ventilation openings are distributed over a circumference of the built-in part downstream of the outlet nozzle.
  • An all-round supply of air can thus be provided.
  • the invention has recognized that the admixture of air already takes place in the annular chamber in front of the outlet nozzle, with the air entering the annular chamber through the outlet nozzle—against the flow direction of the water.
  • the ventilation openings are formed at regular intervals.
  • the annular chamber can thus be supplied with air evenly.
  • the outlet nozzle is formed by an annular gap. Further subdivisions of the aerated jet are thus avoidable.
  • the annular chamber is offset downwards in a longitudinal section with respect to an upstream collection chamber. This allows the water to flow in about in a vertically central portion of the annular chamber. This is favorable for a good admixture of air.
  • the annular chamber extends above and below one or the guide surface. It is thus possible for the water to enter at a distance from a boundary of the annular chamber. This is favorable for good turbulence for air admixture.
  • a plurality of through-openings spaced apart from one another are formed between the collection chamber and the annular chamber. It is thus possible for partial flows that are spatially separate from one another to enter the annular chamber. In the event of a lateral deflection along the annular chamber, this can be used to generate partial flows that meet one another. A further improved turbulence for jet ventilation can thus be achieved.
  • the passage openings described can best be combined with the guide surface also described and/or with the offset arrangement of annular chamber and collecting chamber also described, in order to achieve an approximately central or only slightly eccentric entry of partial flows of the water into the annular chamber. As a result, a particularly effective admixture of air can be achieved.
  • FIG. 1 shows a sanitary installation part, designated as a whole by 1, according to the prior art.
  • the built-in part 1 has a functional unit 2 and a diffuser 3, which is arranged behind the functional unit 2 in a direction of flow.
  • the diffuser 3 is formed on a diffuser insert 4 .
  • the functional unit 2 opens out via a circular inlet opening 5 into the diffuser chamber 6 of the diffuser 3.
  • the diffuser space 6 is delimited by a baffle plate 7 which can be flowed through the inlet opening 5 .
  • This baffle plate 7 deflects the incoming water in a lateral, radial direction.
  • the diffuser chamber 6 is arranged between the baffle plate 7 and the functional unit 2 and is delimited by an outlet opening 9 in the radial direction, which is defined in relation to a central axis 8 .
  • This outlet opening 9 runs around the diffuser space 6 on a cylinder jacket.
  • the baffle plate 7 delimits the diffuser chamber 6.
  • baffle plate 7 On the baffle plate 7 several flow obstacles 10 are formed, each with a triangular horizontal section, which divide the deflected water at the baffle plate 7 into several individual partial flows.
  • the flow obstacles 10 are arranged at a distance from the functional unit 2 so that water can also flow over the flow obstacles 10 .
  • FIG. 2 to 6 show different views of a sanitary fixture according to the invention. These figures are described together below.
  • the exemplary embodiment according to the invention differs from the prior art figure 1 characterized in that the opening cross section of the outlet opening 9 has a surface area which exceeds a surface area of an opening cross section of the inlet opening 5 by at most 10%.
  • the surface areas are even chosen to be the same size.
  • the baffle plate 7 is flat and free of obstacles on the side facing the diffuser chamber 6.
  • outlet opening 9 on the outer edge 11 of the baffle plate 7 is designed to be open all around.
  • step 12 Radially outside the rim 11 is a step 12 which slopes downwards. This step 12 thus forms a cross-sectional enlargement compared to the opening cross-section of the outlet opening 9.
  • the cross-sectional enlargement formed in this way is formed circumferentially around the entire baffle plate 7 .
  • the outer edge 11 forms a circumferential tear-off edge over which the water flow flows downwards.
  • the baffle plate 7 is arranged opposite the inlet opening 5 such that the Inlet opening 5 in the middle or centrally, ie concentrically here, to the baffle plate 7 is located.
  • a central support 13 is formed on the baffle plate 7 and supports the functional unit 2 .
  • the central support 13 can also be formed on the functional unit 2 and can be seated on the impact plate 7 or can engage in a recess formed there.
  • This support 13 forms a flow divider 14 which prevents the water flow from the inlet opening 5 to the central axis 8 and being able to flow over the central axis 8 . Rather, the flow divider 14 causes the water flowing in from the inlet openings 5 to be deflected radially, essentially in a straight line, outwards. The flow divider 14 also fills a central area of the diffuser space 6 which is not required and in which there is a risk of vortex formation.
  • the support 13 is also designed as a carrier plate 37 housing of the volume regulators 15, 16 is supported centrally on the baffle plate 7.
  • the functional unit 2 has two volume regulators 15, 16.
  • the volume regulators 15, 16 are each provided in a manner known per se with an elastically deformable control body as the control element 22, 23, which adjusts an opening cross section of a control gap formed behind the control body as a function of pressure.
  • the control elements 22, 23 are each arranged in an annular gap 20, 21.
  • the quantity regulators 15, 16 are arranged concentrically in one another and nested. The control columns mentioned together form the inlet opening 5.
  • a jet ventilation device 17 is connected downstream in the direction of flow.
  • the jet aeration device 17 has a collection chamber 18 which is connected downstream of the diffuser space 6 and which is opened by the step 12 already mentioned.
  • This collection chamber 18 is annular and opens out via a plurality of radial through-openings 19 into an annular chamber 24.
  • the annular chamber 24 is annular and can be continuously open or partially interrupted by intermediate sections. In the present exemplary embodiment, the annular chamber 24 is designed to be open throughout.
  • the annular chamber 24 is followed by an outlet nozzle 25 which is designed as an annular gap and which follows the course of the annular chamber 24 .
  • Ventilation openings 32 leading to the outside are formed below the outlet nozzle 25 and extend evenly distributed along the circumference.
  • the diffuser space 6 has a constant height, ie vertical dimensions, and thus forms a flow straightener with few, preferably no, obstacles.
  • figure 13 shows an enlarged view figure 2 .
  • An ellipse 26 is fitted or inscribed in the cross section of the annular chamber 24, the aspect ratio of the length of the semi-minor axis to the semi-major axis being equal to 0.53 and thus more than 0.433.
  • ellipses can be fitted whose aspect ratio of the minor semi-axis to the major semi-axis is more than 0.45, 0.5, 0.6 or even 0.69
  • the fitted ellipse 26 thus fills the annular chamber 24 as well as possible.
  • the collection chamber 18 has a guide surface 27 on the bottom, which guides the inflowing water into the annular chamber 24 .
  • This ellipse 28 describes in good approximation the course of the water flow after entering the annular chamber 24 from the guide surface 27.
  • annular chamber 24 has a longitudinal section transverse to its direction of extension, which has a parallelogram shape.
  • a stepped constriction 30 is thus formed at the end of the annular chamber 24 on the outflow side.
  • the outlet nozzle 25 is formed by a circumferential annular gap 20 between the diffuser insert 4 and a housing sleeve 33 .
  • annular chamber 24 is arranged offset downwards or towards an outlet 34 in a longitudinal section in relation to the upstream collection chamber 18 .
  • annular chamber 24 extends both above and below the guide surface 27 in this longitudinal section.
  • FIGS. 7 to 10 show different views of another sanitary built-in part 1 according to the invention. Structurally and/or functionally similar or identical components and functional units to the previous exemplary embodiments are denoted by the same reference symbols and are not described separately again. The remarks on the Figures 2 to 6 therefore apply to the Figures 7 to 10 corresponding.
  • the embodiment according to Figures 7 to 10 differs from the previous exemplary embodiment at least in that the baffle plate 7 is not completely flat, but has a hill-shaped elevation 35 at its radially outer end, through which the outlet opening 9 forms a nozzle.
  • the ramp-shaped elevation 35 is dimensioned in such a way that the impact plate 7 is still essentially level and unobstructed.
  • Figures 11 and 12 12 show a further exemplary embodiment of a sanitary built-in part 1 according to the invention. Again, structurally and/or functionally similar or identical components and functional units are denoted by the same reference symbols and are not described separately. The comments on the previous embodiments therefore apply to the Figures 11 and 12 corresponding.
  • the embodiment according to Figures 11 and 12 differs from the preceding exemplary embodiments in that the annular chamber 24 does not have a parallelogram cross-sectional shape in longitudinal section.
  • a trapezoidal shape is realized here, at least approximately, in which the upper end of the annular chamber 24 is expanded in such a way that the diffuser insert 4 is no longer supported by the solid material of the housing sleeve 33 .
  • plate-shaped projections 36 are formed here, which protrude into the annular chamber 24 .
  • projections 36 are used, on the one hand, to hold the diffuser insert 4 and, on the other hand, to deflect water flows, which flow along the direction in which the circular annular chamber 24 extends, radially inwards. This further improves the mixing of the water currents.
  • These projections 36 are preferably designed to correspond to the position of the passage openings 19 .
  • the Figures 15 and 16 show the ellipses 26, 28 analogous to the Figures 13 and 14 for the situation of the built-in part 1 according to the Figures 11 and 12 .
  • the fitted ellipses 26, 28 are aligned obliquely with respect to the central axis 8, which defines the longitudinal direction of the built-in part 1.
  • the ellipse 26 has an aspect ratio of 0.55 from the minor semi-axis to the major semi-axis, ie it is above a ratio of 0.52.
  • the ellipse 28, on the other hand, has an aspect ratio of approximately 0.69 from the minor semi-axis to the major semi-axis.
  • Figures 17 and 18 show representations analogous to the Figures 13 and 14 . Structurally and/or functionally similar or identical components and functional units are denoted by the same reference symbols and are not described separately. The remarks on the Figures 1 to 16 therefore apply to the Figures 17 and 18 corresponding.
  • Figures 19 and 20 show different views of another sanitary installation part 1 according to the invention. These figures are described together below. Structurally and / or functionally to one of the preceding built-in parts according to Figures 1 to 18 Similar or identical components and functional units are denoted by the same reference symbols and are not described separately again. The remarks on the Figures 1 to 18 therefore apply to the Figures 19 and 20 corresponding.
  • the mounting part 1 according to Figures 19 and 20 differs from the preceding exemplary embodiments in that the diffuser chamber 6 does not have a profile 39 with a constant height. Rather, a profile widening 40 is formed along the main flow direction 38 between the upstream inlet opening 5, which is assigned to the quantity regulator 15, and the downstream inlet opening 5', which is assigned to the quantity regulator 16, through which the cross-sectional area of the diffuser chamber 6 of a cylinder jacket extends around the Axis 8 changes outwards more than proportionally to the radius of the cylinder surface. As a result of this increase in surface area, the additional water flow, which flows through the downstream inlet opening 5' into the water flow from the upstream inlet opening 5, can be absorbed without the formation of significant vortices.
  • the profile ramp 41 can be formed additionally or alternatively on the functional unit 2 .
  • the gradient of the profile ramp 41 is chosen such that the profile widening 40 defines an increase in the area of a cross-sectional area of the diffuser space 6 transverse to the main flow direction 38, which is matched to an area of a cross-sectional area of the downstream inlet opening 5'. It can thus be said that the surface area of a cylinder jacket around the axis 8 in the diffuser chamber 6 behind the profile widening 40 is greater than the corresponding surface area in front of the profile widening 40 by the area of the downstream inlet opening 5 ′.
  • the invention uses the continuity equation here in order to achieve an approximately constant flow rate.
  • the embodiment according to Figures 19 and 20 also differs from the previous exemplary embodiments in that the flow divider 14 is not formed as a pin on the baffle plate 8, but rather—pointing downwards—on the functional unit 2. the Functional unit 2 is thus supported on baffle plate 8 and on diffuser insert 4 .
  • an area of an opening cross section of an outlet opening 9 of the diffuser 3 should be designed at most 10% larger than an area of an opening cross section of an inlet opening 5 , 5' of the diffuser 3 and/or the annular chamber 24 with a contour which, in a longitudinal section of the built-in part 1, allows an ellipse 26, 28 to be inscribed with the smallest possible eccentricity.
