Description

Technical Field

[0001] The invention relates to a sanitary mounting.

[0002] The invention also relates to a series of structures comprising at least two variants of sanitary fittings. Summary of the invention

[0003] The object of the present invention is to provide a sanitary fitting of the type mentioned at the outset which has improved usage properties.

[0004] This object is achieved according to the invention by a sanitary fitting and / or by a series of components having the features described below.

[0005] In particular, according to the invention, in order to achieve this object, a sanitary fitting of the type mentioned at the outset is proposed, which comprises at least one functional unit for determining the flow rate and a diffuser arranged downstream of the functional unit for determining the flow rate in the flow direction, wherein the diffuser has a diffuser space which is partially delimited by a collision surface which deflects water flowing into the diffuser space in a lateral direction, the diffuser space having a plurality of outlet openings, a runoff slope adjoining the collision surface which causes water incident on the collision surface and flowing away from the collision surface to flow away in the use position towards the outlet openings, characterized in that the outer edge of the runoff slope is formed by a step and the runoff slope is inclined downwardly and / or from the inside to the outside at an angle relative to the collision surface. This has the advantage that the sanitary fitting can also be used at relatively low flow rates (e.g., at most or exactly 1 gallon per minute (gpm)) in order to form an aesthetically shaped and / or aerated water jet.

[0006] At such low flow rates, sufficient aeration of the water jet can no longer be achieved with sanitary fittings of previously known type, so that the jet shape of the emerging water jet appears inhomogeneous. In addition, compared to previously known sanitary fittings of the type mentioned at the outset, the generation of noise, which is often perceived as disturbing, can be better prevented because the turbulence in the fitting, in particular in the diffuser space and / or in the flow direction behind the outlet opening, is less than in previously known fittings.

[0007] Furthermore, in particular according to the invention, a sanitary fitting of the type mentioned at the outset is proposed for achieving the stated object, characterized in that the outlet openings penetrate the circumferential side wall of the diffuser, the outlet openings each have a width b, two adjacent outlet openings are each arranged at a distance a from one another, and the ratio b / a is less than 0.41. It has proven to be particularly advantageous to have a ratio b / a of less than 0.41 in fittings with relatively low flow rates (low flow rate levels), since above this value a poorly aerated and / or unaesthetically shaped water jet occurs. This ratio can therefore achieve sufficient aeration of the water jet, in particular at relatively low flow rates, for example 1 gpm.

[0008] The two previously described independent solutions can also be combined with one another to form an advantageous embodiment.

[0009] Advantageous embodiments of the invention are described below, which can be optionally combined with the above-described features alone or in combination with features of other embodiments.

[0010] According to an advantageous further development, it can be provided that the diffuser chamber has at least one inlet opening, wherein in the use position the water jet entering through the at least one inlet opening impinges on the impact surface and is dispersed. Thus, good aeration of the water jet is possible even at low flow rates. In particular, a plurality of inlet openings can also be provided, which are preferably all oriented toward the impact surface. In particular, the at least one inlet opening can be formed by a functional unit.

[0011] In order to be able to achieve a particularly good distribution of the water jet, the impact surface can be oriented perpendicularly or almost perpendicularly with respect to the angle of incidence of the incoming water jet in the position of use.

[0012] In order to accelerate the flow of water incident on the collision surface, according to another advantageous design, it can be provided that the flow-off bevel is inclined downward and / or from the inside to the outside at an angle relative to the collision surface. In particular, the angle can be at least 5 degrees, in particular at least 10 degrees, in particular at least 15 degrees, in particular at least 20 degrees, in particular at least 25 degrees, preferably about 30 degrees.

[0013] According to another advantageous embodiment, the diffuser space can be designed in an annular shape. Alternatively or in addition thereto, it can be provided that the discharge opening is at least partially designed as a material recess extending outward, preferably a material recess extending radially outward. In particular, the material recesses can each have a shortest path length corresponding to at least 2%, in particular at least 3%, in particular at least 4%, in particular at least 5%, in particular at least 6%, in particular at least 7%, in particular at least 8%, in particular at least 9%, in particular at least 10% of the diameter of the diffuser space. Thus, the water jet discharged from the discharge opening can be rectified before discharge so that a uniformly aerated jet shape can be generated.

[0014] According to an advantageous embodiment, it can be provided that the diffuser space is formed between the impact surface and the functional unit that determines the flow rate. Alternatively or additionally, it can be provided that a diffuser ring is formed or arranged downstream of the outlet opening.

[0015] According to another advantageous embodiment, it can be provided that the functional unit for determining the flow rate has at least one quantity limiter and / or at least one throttle valve. It is thus possible to introduce a predeterminable quantity into the diffuser. It can be particularly advantageous if the functional unit has at least one quantity limiter so that a required and / or desired flow rate can be provided in the working area independently of the pressure. The flow conditions in the diffuser space can thus be better controlled.

[0016] According to a particularly advantageous embodiment, it can be provided that the sanitary fitting has a housing in which the diffuser and / or the at least one flow-determining functional unit are at least partially inserted. Preferably, the housing can have a surrounding, in particular closed wall which laterally delimits a, in particular annular, receiving chamber downstream of the outlet opening in the flow direction. The housing can be designed, for example, as a diffuser ring which forms an outer and / or lateral delimitation of the annular chamber / receiving chamber.

[0017] In order to achieve particularly good dispersion of the water jet incident on the collision surface, according to an advantageous further development, it can be provided that at least one disperser element is arranged next to and / or on the collision surface, in particular on the edge of the collision surface. In this case, in particular, a plurality of disperser elements, preferably arranged on a circular trajectory, can be arranged on the collision surface. Alternatively or in addition, the disperser elements can be arranged as flow obstacles in the radial direction and / or with respect to the flow direction, for example the flow direction already mentioned above, respectively upstream of an outlet opening.

[0018] In order to better prevent eddies in the diffuser space, a collecting chamber can be formed between the outlet opening and the outer edge of the flow-off slope in the diffuser space according to an advantageous further improvement. Preferably, the height of the diffuser space in the region of the collecting chamber can be higher than the height of the diffuser space in the region of the collision surface. Alternatively or additionally, according to an advantageous further improvement, it can be provided that the outer edge of the flow-off slope, for example the previously mentioned outer edge of the flow-off slope, is formed by a step. As a result, the flowing water at this position falls from the diverting edge of the flow-off slope, in particular the blunt diverting edge, whereby it is accelerated before it flows through the outlet opening.

[0019] In order to achieve the above-mentioned object, a series of at least two variants for a sanitary fitting is furthermore proposed, in particular at least one of the at least two variants corresponds to the sanitary fitting as described and claimed here.

[0020] The structural series has at least one functional unit, at least one housing and at least two different types of diffusers. The housing can be designed, for example, as a diffuser ring. The structural series is characterized in that the at least two variants have different types of diffusers, which have outlet openings of different configurations that determine the flow rate. In this case, in particular, the first type can have a smaller flow rate level than the second type. As already explained before, in the first variant, it can be related to the following flow rate level, whose flow rate is at a maximum of 1 gpm, in particular exactly 1 gpm or less than 1 gpm. Correspondingly, the second variant has a higher flow rate level with a flow rate of more than 1 gpm.

[0021] In other words, a structural series with at least two variants of a sanitary installation is proposed, wherein each variant has at least one functional unit, at least one housing and / or diffuser ring and at least one diffuser, characterized in that the at least two variants have different types of diffusers, which have outlet openings with different structures that determine the flow rate, in particular, the first variant has a smaller flow rate level than the second variant.

[0022] Next, advantageous design of the present invention is described, which can be combined with the feature alone or in combination with the feature of other design. In addition, in particular, the feature of the sanitary installation described and / or claimed here can be adopted to form other designs according to the present invention.

[0023] According to an advantageous further development, it can be provided that the ratio of the width b of the outlet opening to the distance a between two adjacent outlet openings is smaller in the case of a diffuser of the first type than in the case of a diffuser of the second type. It can thus be achieved that, with the aid of this structural series, sanitary fittings with different flow rate levels (and / or variations of flow rate levels) can be provided, wherein only different types of diffusers need to be used in order to achieve this. Thus, the correct diffuser can be selected according to the flow rate and installed in the housing in order to form a sanitary fitting.

[0024] According to a particularly preferred embodiment of this series, it can be provided that the first variant is designed as a sanitary fitting according to the invention.

[0025] In order to be able to produce sanitary fittings with different flow rate ratings, it can be provided that the ratio b / a of the first variant is less than 0.41 and / or that the ratio b / a of the second variant is 0.41 or greater than 0.41.

[0026] In order to make the manufacturing cost of the sanitary fittings which can be manufactured by means of a series structure as low as possible, it can be provided according to another advantageous design that the housing and / or diffuser ring of the at least two variants are structurally identical. The housing can be a diffuser ring or can be a different component.

[0027] According to a further development, it can be provided that the second variant has no flow-off bevel on the diffuser. Thus, different flow characteristics can be achieved here compared to the first variant. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 6 Show Figure 4 sectional view of a sanitary installation, wherein a functional unit is also provided upstream of the diffuser in the flow direction, and Figure 6 The embodiment of FIG. 5 differs from the embodiment of FIG. 5 only in the diffuser type. DETAILED DESCRIPTION

[0036] Fig. 1, 3 and 5 show the embodiment variant of the sanitary fitting previously known by the prior art, which is designed to shape the water jet discharged from the faucet. For this reason, the water jet is aerated by sucking air, which is mixed with water in the fitting.

[0037] The invention therefore relates to a sanitary fitting, which is in particular designed as a jet regulator, preferably as a pneumatic jet regulator. Such a fitting usually has at least one functional unit 2 for determining the flow rate and a diffuser 4 arranged downstream of the functional unit 2 for determining the flow rate in the flow direction 3.

[0038] Such a diffuser 4 has a diffuser chamber 5 , which is at least partially delimited in terms of its dimensions by a collision surface 6 .

[0039] The impact surface 6 is designed to deflect water flowing into the diffuser space 5 in the use position and / or during operation in the lateral direction. The diffuser space 5 itself has a plurality of outlet openings 7, through which the water jets dispersed on the impact surface 6 are discharged from the diffuser space 5 in the form of individual jets.

[0040] However, it has been found that even at low flow rates, which may be in the range of 1 gpm + / - 10%, in particular + / - 20%, sufficient aeration of the water jet flowing through the mounting part, shaped therein and aerated cannot be achieved. Therefore, the previously known mounting parts cannot produce a satisfactory discharge jet shape desired by the customer.

[0041] Figure 2 , 4 6 show a possible embodiment variant of the sanitary fitting according to the invention, which is designated overall by 1 .

[0042] The sanitary fitting 1 has the advantage over previously known fittings that even small water flows can be sufficiently aerated thereby to produce a satisfactory aerated discharge jet shape.

[0043] In order to be able to adequately disperse the water volume flowing into the diffuser chamber 5 therein, the diffuser chamber 5 has a collision surface 6 which at least partially delimits the diffuser chamber 5 , as already described above for previously known installations.

[0044] The sanitary insert 1 is now characterized in that a runoff bevel 8 is connected to the impact surface 6, which accelerates the water incident on the impact surface 6 and flowing away therefrom and flows away toward the outlet opening 7. The runoff bevel 8 can thus be used to accelerate the running water in order to convey it toward the outlet opening 7.

[0045] Furthermore, it has proven to be advantageous if the outlet opening 7 determines a lateral outlet direction, in particular a lateral outlet direction which runs parallel or approximately parallel to the impact surface 6 . This can be achieved in that the outlet opening 7 passes through the surrounding side wall 9 of the diffuser 4 .

[0046] The outlet openings 7 each have a width b, 10. Adjacent outlet openings 7, in particular all adjacent outlet openings 7, can be arranged at the same distance a, 11 from one another. With regard to the creation of an optimized outlet jet shape at low flow rates in the mounting part 1 according to the invention, it has proven to be advantageous if the ratio b / a (b divided by a) is less than 0.41.

[0047] The diffuser 4 has at least one inlet opening 12, wherein in the use position, the water jet entering through the at least one inlet opening 12 impinges on the collision surface 6 and is dispersed. The at least one inlet opening 12 is thus designed so that the entry direction of the water jet is determined thereby so that the water jet impinges on the collision surface 6, in particular only on the collision surface 6. The sanitary fitting 1 can have a plurality of inlet openings 12, which are in particular all oriented toward the collision surface 6 and / or are arranged above the collision surface 6.

[0048] The collision surface 6 is oriented in relation to the incoming water jet in such a way that a high flow resistance is generated. This can be achieved in that the collision surface 6, which can be formed as a collision plane, is oriented perpendicularly or almost perpendicularly to the angle of incidence of the incoming water jet in the use position.

[0049] The flow away bevel 8 is inclined downward and / or from the inside to the outside at an angle relative to the collision surface 6, especially relative to the plane of the collision surface 6. The angle can be at least 5 degrees, especially at least 10 degrees, especially at least 15 degrees, especially at least 20 degrees, especially at least 25 degrees, preferably about 30 degrees.

[0050] The diffuser space can be designed in an annular or disk-shaped manner.

[0051] 1 to 6, the outlet opening 7 is at least partially designed as an outwardly extending material recess 13. The material recess 13 can thus act like a channel in order to reduce flow turbulence.

[0052] The material gaps 13 can each have a shortest path (shortest distance) corresponding to at least 2%, in particular at least 3%, in particular at least 4%, in particular at least 5%, in particular at least 6%, in particular at least 7%, in particular at least 8%, in particular at least 9%, in particular at least 10% of the diameter 14 of the diffuser space 5.

[0053] The diffuser space 5 is formed between the collision surface 6 and the functional unit 2 which determines the throughflow, wherein the diffuser space is delimited on the inflow side by the functional unit 2 and on the outflow side by the collision surface 6 .

[0054] The flow-determining functional unit 2 has at least one flow limiter 15 and / or at least one throttle valve. In general, it can be said that the functional unit changes or can change the flow and / or there is a pressure difference between the sections before and after the functional unit.

[0055] A quantity limiter 15 in the sense of the invention may be a pressure-independent, in particular automatic, regulation of the flow rate via the working range of the quantity limiter 15. Thus, a flow rate that is as constant as possible can be regulated. In contrast, in a throttle valve the flow rate varies depending on the prevailing pressure.

[0056] The sanitary fitting 1 has a housing 16 , in which the diffuser 4 and / or the at least one flow-determining functional unit 2 are at least partially inserted.

[0057] The housing 16 has a wall 17 which laterally delimits a particularly annular receiving chamber 18 downstream of the outlet opening 7 in the flow direction 3. The receiving chamber 18 can be used for aerating the water jet and can therefore also have a filling opening for sucking in air, particularly from the outside.

[0058] The housing 16 thus has an influence on the flow characteristics of the water flowing through. The housing 16 thus defines, together with the diffuser 4, the flow direction 3 of the water through the mounting 1 and / or contributes to the jet shaping and / or jet aeration. Thus, there is an interaction between the diffuser 4 and the housing 16 which determines the shape of the discharge jet, so that the housing 16 can also be referred to as a diffuser ring 23.

[0059] A plurality of diffuser elements 19, in particular arranged on a circular path, are formed on the edge and / or beside the collision surface 6. The diffuser elements 19 are located upstream of the outlet opening in the flow direction 3. In the embodiment variant shown, they divide the outer edge 20 and / or the edge of the flow-off bevel 8 into a plurality of partial sections.

[0060] The diffuser element 19 can be designed, for example, as a ramp and / or a wedge which rises towards the outlet opening, as shown in FIGS. 1-6 .

[0061] A step 22 is formed after the runoff bevel 8, which leads to a collecting chamber 21 downstream of the runoff bevel in the flow direction 3. The collecting chamber 21 thus forms part of the diffuser chamber 5. The height of the collecting chamber 21 is higher than the rest of the diffuser chamber 5, in particular in the region of the collision surface 6.

[0062] Furthermore, FIGS. 1 to 6 relate to a series of structures comprising at least two variants 24 , 25 of the sanitary fitting 1 .

[0063] Variants 24 and 25 differ here only in the type of diffuser installed therein.

[0064] The functional units 2 and / or the housing 16 , in particular the diffuser ring 23 , of both variants 24 , 25 are designed to be structurally identical.

[0065] The at least two variants 24 , 25 of the series have different diffusers 4 which differ in that the at least two types of diffusers 4 have outlet openings 7 of different opening sizes. The first variant 24 is therefore adapted to a smaller flow rate class than the second variant 25 .

[0066] Furthermore, it can be said that the ratio of the width b of the respective outlet opening 7 to the respective distance a between two adjacent outlet openings 7 is smaller in the first variant 24 than in the second variant 25 .

[0067] More precisely, it can be said that the ratio b / a of the first variant 24 is less than 0.41 and / or the ratio b / a of the second variant 25 is 0.41 or greater than 0.41.

[0068] As can be seen from FIGS. 1 and 3 , the diffuser 4 of the second variant 25 does not have a runoff bevel 8 . Instead, the collision surface 6 is extended here and forms a sharp, in particular right-angled edge. The water thus flows over the sharp diverging edge and falls into the collecting chamber 21 .

[0069] That is, the present invention particularly relates to a sanitary installation component 1, which includes at least one functional unit 2 for adjusting the flow rate and a diffuser 4 arranged downstream of the functional unit 2 for adjusting the flow rate in a flow direction 3, wherein the diffuser 4 has a diffuser space 5, which is partially defined by a collision surface 6, which deflects water flowing into the diffuser space 5 in a radial direction toward a plurality of outlet openings 7, wherein a flow-off bevel 8 is arranged obliquely to the collision surface 6, which causes water incident on the collision surface 6 and flowing away from the collision surface to flow away toward the outlet openings 7 in the use position.
