Abstract

In the sanitary installation (1), it is proposed that a connecting element (8) be arranged in the interior (7) of the housing (2) at a distance therefrom and be used to latch the upstream screen (5) on the inflow side and the outlet structure (4) on the outflow side.

Description

Sanitary insert

Technical Field

The invention relates to a sanitary insert, comprising: a housing having an outlet structure formed on a downstream side thereof; and a pre-strainer disposed on the upstream side.

Background

Such inserts are known and are for example inserted into the outlet of a faucet in order to achieve a desired jet mass and/or throughflow rate per unit time. Non-exhaustive examples of jet masses include: aerated jets, single jet arrangement, non-circular jet cross-section. The flow rate per unit time, which is independent of the pressure, can be set within the operating range by means of the flow rate regulator. It is also known to construct the insert with a defined switching behavior, for example as a function of the water temperature. It is also known to equip the sanitary insert with means for switching between different jet masses and/or throughflows.

Such inserts are usually composed of a pot-shaped housing and a plurality of components which are located inside and perform the respective function. These components are therefore also referred to as functional units. The housing and the component are often designed in such a way that the component is held on its respective circumference by means of a snap-in connection.

Disclosure of Invention

The aim of the invention is to simplify the structural design of the sanitary insert.

To achieve this object, the features of claim 1 are specified. In order to achieve the object, it is therefore proposed, in particular according to the invention, in a sanitary insert of the type mentioned at the outset that the upstream screen is latched to the outlet structure via a connecting element which extends through the interior of the housing. The fastening of the inner component to its periphery can therefore be dispensed with. Thus simplifying the structural construction. This can be used, for example, to provide a larger clear inner diameter for the water flow if the outer dimensions remain equal, since no radial installation space has to be reserved for the fixation on the circumferential side. By arranging the connecting element in the interior space, i.e. for example at a distance from the inner wall of the housing, the connecting element is displaced into a non-critical region inside the jet. Interfering effects on jet shape and/or other jet quality can be reduced.

In an advantageous embodiment, it can be provided that a functional unit is arranged in the interior of the housing, through which interior the connecting element is inserted. The connecting element can therefore additionally be used to orient the functional unit.

In this case, it can be provided that a jet splitter is arranged in the interior of the housing, through which jet splitter the connecting element is inserted. Lateral stabilization of the connecting element can thus be achieved. Lateral fixation of the jet splitter can also be achieved.

The jet splitter can be designed, for example, as a diffuser with a diffuser ring or as a splitter plate.

Alternatively or additionally, it can be provided that at least one deflection insert is arranged in the interior of the housing, through which deflection insert the connecting element is inserted. The deflecting insert can be provided, for example, for deflecting the water jet exiting from the jet splitter. The support of functional units arranged further upstream, for example jet splitters, can thus be achieved.

Alternatively or additionally, it can be provided that at least one screen insert is arranged in the interior of the housing, through which the connecting element is inserted. Thus, the at least one screen insert can be fixed laterally and the connecting element can be supported laterally.

It is particularly advantageous if the jet splitter and the at least one filter insert are plugged together by the connecting element. A compact, particularly stable arrangement can thus be achieved.

In an advantageous embodiment, it can be provided that at least one shoulder is formed on the connecting element, on which shoulder at least one functional unit, in particular the at least one functional unit already mentioned, is supported. As a result, the water pressure which arises as a result of the flow resistance of the functional unit, i.e., for example, the already mentioned jet splitter and/or the already mentioned at least one screen insert and/or the already mentioned deflector unit, can be absorbed. The arrangement of the connecting element in the housing interior can result in a more advantageous introduction of force than hitherto customary support on the periphery.

In an advantageous embodiment, it can be provided that a functional unit, such as the functional unit already mentioned, is latched to the connecting element. Additional axial fastening can thus be achieved. This again improves the holding together of the parts in the axial direction.

In an advantageous embodiment, it can be provided that a latching connection is formed on the upstream screen. The latching connection can thus be established under visual inspection.

In an advantageous embodiment, it can be provided that the outlet structure is formed with a latching connection. The housing with the outlet structure can thus be formed in a simple manner, in particular by demolding.

In an advantageous embodiment, it can be provided that the latching connection is formed in the connecting element. The connection between the upstream screen and the outlet structure, which allows the locking, can thus be arranged at any suitable point. This can be achieved, for example, according to the requirements and/or mechanical stability of the injection mold. In this way, the latching connection can also be reinforced or locked by means of plug-in components, such as jet splitters and/or screen inserts.

In other embodiments, a plurality of connections can also be formed, for example on the pre-filter screen and on the outlet structure, on the pre-filter screen and in the connecting element, in the connecting element and on the outlet structure, or at all three points. The invention makes it possible to realize different connections in a simple manner, for example also in a series of sanitary inserts with identical housing, upstream screen and/or outlet structures and with mutually different connecting elements.

In an advantageous embodiment, it can be provided that the upstream screen insert is mounted on the connecting element. A particularly simple to produce and/or to operate interface can thus be formed.

In an advantageous embodiment, it can be provided that the connecting element is inserted into a receptacle on the outlet structure. Additional breakages in the outlet structure can thus be avoided.

In an advantageous embodiment, it can be provided that the housing is configured without undercuts in the interior space at least below the jet splitter, in particular the jet splitter already mentioned. Thus, a housing shape which can be easily demoulded can be achieved at least below the jet splitter.

Preferably, the housing is designed without undercuts, for example stepped, in the interior over its entire axial length. The latching connection on the circumferential side can thus be completely dispensed with. In addition or alternatively, circumferential support of the internal functional components can thus be achieved.

For example, it can be provided that the housing has a cylindrical inner contour at least below the jet splitter. It is advantageous here to avoid a diameter reduction in the interior space.

Preferably, the housing is formed with a cylindrical inner contour in the inner space over its entire axial length. It is thus possible to provide a universal housing for different functional components.

In an advantageous embodiment, it can be provided that the connecting element is designed as a retaining pin. Thus, the adverse effect of the connecting element on the water jet can be made small.

In an advantageous embodiment, it can be provided that the connecting element is arranged on the longitudinal center axis of the housing. A symmetrical arrangement can thus be achieved in which the connecting elements remain hidden as well as possible from all directions of view.

In an advantageous embodiment, it can be provided that the outlet structure is integrally formed on the housing. A stable and/or sealed support of the outlet structure and the connecting element can thus be achieved.

In an advantageous embodiment, it can be provided that the sieve is supported on the housing at its outer circumference. Stabilization of the insert parts can thus be achieved, for example, by axial support, in the axial direction against disengagement from one another, or by radial support against lateral sliding.

In an advantageous embodiment, it can be provided that the housing is formed in one piece. A housing of particularly simple construction can thus be used, in particular if the housing is formed without undercuts or even cylindrical.

In an advantageous embodiment, it can be provided that the housing is accommodated by a threaded sleeve. Different fitting types can thus be realized without having to match the housing.

In this case, it can be provided that the threaded sleeve forms and/or defines at least one inflation channel between itself and the housing. A simple aerated jet shape can thus be achieved.

Detailed Description

Fig. 1 to 4 are described together below.

The sanitary insert, designated as a whole by 1, has a housing 2. The housing 2 can be designed in one piece or in multiple pieces as shown in the drawing.

On the downstream side 3, an outlet structure 4 is formed, which shapes the outgoing water jet in a manner known per se.

The pre-strainer 5 is arranged on the opposite side 6 upstream of the sanitary insert 1.

The housing 2 defines an interior space 7. Through the free interior 7, a connecting element 8 is provided, which connects the outlet structure 4 to the upstream screen 5.

By means of the connecting element 8, the upstream screen 5 is latched to the outlet structure 4 in a manner which will be described in more detail below.

A plurality of function units 9 are provided in the internal space 7 of the housing 2.

The connecting element 8 passes through each functional unit 9.

In the present exemplary embodiment, it can be seen that the functional unit 9 arranged directly downstream of the upstream screen 5 is designed as a jet splitter 10.

In the present exemplary embodiment, the jet splitter 10 is designed as a splitter plate. In other embodiments, the jet splitter 10 may also be configured as a diffuser with a diffuser ring.

In other embodiments, at least one flow regulator can also be provided upstream of the jet splitter 10, for example, for regulating the pressure-independent throughflow.

In the exemplary embodiment according to fig. 1 to 4, a further functional unit 9 in the form of a deflecting insert 11 is formed downstream of the jet splitter 10.

As can be seen well in fig. 2, the deflecting insert 11 is formed inward in such a way that the jet emerging from the jet splitter 10 is deflected radially inward in order to achieve good mixing below the jet splitter 10.

In other embodiments, a filter insert known per se can additionally or alternatively be provided in the interior space 7.

In the exemplary embodiment according to fig. 1 to 4, a mechanical interface 12 is formed at the respective ends of the upstream screen 5 and the connecting element 8, which interface establishes a latching connection.

The opposite end of the connecting element 8 is integrally formed on the outlet construction 4.

The sieve 5 is therefore inserted onto the connecting element 8 in order to establish a snap-fit connection. A thickening 13 is formed on the connecting element 8, which thickening interacts with a radial slot 14 in the upstream screen 5 in order to establish a latching connection.

As can be seen well in fig. 3, the housing 2 has a cylindrical inner contour 15 without undercuts.

The functional units 9 are thus supported axially on the outlet structure 4.

It can be seen that the connecting element 8 is designed as a retaining pin 16 which is arranged centrally with respect to a longitudinal center axis 17 of the housing 2.

As can be seen in the sectional view according to fig. 2, the outlet structure 4 is integrally formed on the housing 2 and is therefore integrally connected thereto.

The upstream screen 5 is supported on its outer circumference 20 on the housing 2 via a circumferential sealing ring 18. The upstream screen 5 is also supported on its outer circumference 20 on the outlet structure 4 and thus also on the housing 2 via the functional unit 9 and the sealing ring 18.

A support sleeve 19, via which the upstream screen 5 is supported in the middle, is formed on the jet splitter 10.

The housing 2 is in this embodiment fitted into a threaded sleeve 21.

The threaded sleeve 21, as a screwing sleeve, has an external thread 22 in a manner known per se, which, as shown in fig. 4, can be screwed to a tap outlet 23. Here, the sealing ring 18 can effect the sealing.

In other embodiments, the external thread 22 may be formed directly on the housing 2. An internal thread can also be formed on the housing 2 or on the threaded sleeve 21 (screw sleeve) in order to establish a threaded connection with the tap outlet 23. In other embodiments, other connections are provided, such as a snap-in connection and/or an anti-twist connection.

The housing 2 has, in a known manner, inflation windows 24 which open out via inflation channels 25 between the threaded sleeve 21 and the housing 2.

Fig. 5 and 6 show another embodiment according to the invention. Components and functional units that are functionally and/or structurally identical or similar to the preceding embodiments are denoted by the same reference numerals and are not described once separately. The description of fig. 1 to 4 therefore applies correspondingly to fig. 5 and 6.

The embodiment according to fig. 5 and 6 differs from the preceding embodiments in that the connection 12 is not formed on the upstream screen 5, but in the connecting element 8.

Thus, a portion of the connecting element 8 is integrally formed on the outlet structure 4, while a second portion of the connecting element 8 is integrally formed on the front screen 5.

Fig. 7 shows another embodiment according to the invention. The components and functional units that are functionally and/or structurally identical or similar to the embodiments described above are also denoted by the same reference numerals and are not described once in isolation. The description of the preceding embodiment therefore applies correspondingly to fig. 7.

The embodiment according to fig. 7 differs from the preceding embodiments in that the mechanical interface 12 is formed on the outlet structure 4. In this case, the connecting element 8, which can be integrally formed on the sieve attachment 5, is thus latched to the outlet structure 4 via the thickening 13.

Fig. 8 shows another embodiment according to the invention. The components and functional units that are functionally and/or structurally identical or similar to the embodiments described above are also denoted by the same reference numerals and are not described once in isolation. The description for fig. 1 to 7 therefore applies correspondingly to fig. 8.

The embodiment according to fig. 8 differs from the previous embodiments in that the connecting element 8 does not have a diameter that remains substantially equal, but rather a shoulder 26 is formed at the height of the functional unit 9, on which the functional unit 9, in this case the jet splitter 10, is supported centrally.

In the sanitary insert part 1, it is therefore proposed to arrange the connecting element 8 in the interior 7 of the housing 2 at a distance from the latter and to lock the inflow-side upstream screen 5 and the outflow-side outlet structure 4.
