Description

Sanitary insert

The invention relates to a sanitary insert part, which can be used in a water pipe and, if necessary, removably arranged and releasably connectable at its inflow-side end face with a filter or attachment screen.

It has already been created various sanitary inserts that can be used in the outlet mouthpiece of a sanitary water spout or in an interposed in the sanitary supply line cartridge insertion and removed from there, for example, for the purpose of replacement or maintenance if necessary removed. These known insert parts have a jet regulator, a flow rate regulator, a backflow preventer or a combination of these functional units. Since the functional units forming such a sanitary insert part have jet separators, valve openings, control gaps or similar cross-sectional constrictions, these functional units can be impaired in their function by the dirt particles entrained in the water. In order that such dirt particles can not impair the function of the sanitary insert parts and their functional units, these insert parts are preceded in each case by an attachment or filter screen in the flow direction. This attachment or filter screen can usually be fastened to the upstream end side of the insert part by means of a latching connection, so that the unit consisting of attachment or filter screen and insert part does not unintentionally release during storage, transport or assembly, and the insert part without the attachment element.

BESTÄTÜGOMGS & OPIE or filter screen can be mounted. This latching connection between the mostly cap-shaped attachment or filter screen on the one hand and the insert part on the other hand is usually so fixed and mounted on the insert attachment or filter sieve is usually so difficult to grasp that the Vorsatzoder filter, for example, for cleaning purposes regularly not without tools and usually not non-destructively separated from the insert part and can be removed.

There is therefore in particular the task of creating a sanitary insert part of the type mentioned, which can be separated quickly and easily destructively from the insert as needed and remove.

The achievement of this object is in the insert part of the type mentioned in particular that protrudes designed as a handle projection in particular for the purpose of tool-free disassembly on the inflow side of the filter or attachment screen.

At the upstream side of the attachment or filter screen associated with the insertion part according to the invention, there is a projection that is configured as a handle. The attachment or filter sieve can be gripped and clamped between the fingertips on this protrusion designed as a handle in order to be able to disassemble and remove the sieve from the insertion part non-destructively and without tools, even when the connection between the attachment and filter sieve and insertion part is tight. Since a non-destructive disassembly of the filter or filter sieve is now possible, the sieve can be reused, for example, after the cleaning resource-saving.

It goes without saying that this was assigned to a sanitary insert and according to the invention with a handle designed as a handle. Deten projection equipped filter or attachment strainer has a greater installation length. A preferred embodiment according to the invention therefore provides that the projection in its cross-section to the clear cross-section of the upstream in the inflow 5 direction arranged before the insertion line section is adapted. If the protrusion is adapted to the line section arranged in the inflow direction in front of the insert part, the insert part can optionally also be subsequently combined with the filter or attachment screen equipped according to the invention with a projection 10, without complications during installation being expected.

I

In order that the attachment or filter screen arranged on the inflow side of the sanitary insert part is separated from the inflowing water

If the outer peripheral wall forming the projection is arranged at a radial distance from the inner circumference wall of the line section which revolves around the projection, it is advantageous for the flow to flow around completely and to exert its filter function over its entire filter surface.

20

A preferred embodiment, which may also be in spite of the above filter or attachment screen

^ can accommodate later in the arranged before the insert part line section, provides that the

25 attachment or filter has a plate or plate-shaped peripheral edge portion.

A secure, yet easily detachable connection between attachment or filter screen, on the one hand, and the sanitary insert part, on the other hand, is favored if the attachment or filter screen can be detachably connected at its peripheral edge to the inflow-side end face of the insertion part by means of a screwed, latched or recessed connection is.

35 In order that the intentional or filter sieve over a maximum filter surface can exert its filter function, it is advantageous if the Vorsatzoder filter has in the region of its peripheral edge portion and / or its projection flow or filter openings.

A preferred embodiment according to the invention, which is particularly good grip between the fingertips and can be clamped and at the same time can also provide a particular additional filter surface, provides that the projection of the attachment or filter screen as preferably cylindrical and at its free front end in particular closed hollow body is designed.

It is advantageous if the particular cylindrical projection on the free end face and / or on the peripheral wall has flow openings. The attachment or filter screen can catch dirt particles that may be present in the incoming flow of water at an early stage in the area of the free end face of the projection, in such a way that these dirt particles are subsequently displaced and accumulated by the water flow in the downstream line sections. In order to achieve the largest possible filter surface in the region of the projection, flow openings are additionally or instead also possible on the circumferential wall.

In order to achieve the largest possible filter surface, it is advantageous if the flow openings provided on the projection and / or on the peripheral edge region of the attachment or filter screen have a honeycomb-shaped clear cross section.

The preparation of the inventively provided Vorsatzoder filter screen is substantially facilitated if the on the peripheral wall of the particular cylindrical projection provided flow openings are designed slot-shaped. Compared to flow holes, these slit-shaped flow openings offer a large clear opening cross-section, without the risk that larger particles of dirt can pass through these slit-shaped flow openings.

In order to solve the intent or filter, for example, by tilting movements of the sanitary insert without the risk of destruction of intent or filter screen, it is appropriate that the intent or filter screen in its peripheral edge region and / or in the region of its projection flow-opening Ribs, webs or the like stiffeners has. Since the flow openings always represent material weaknesses of the attachment or filter screen, can be achieved with these stiffeners gain the attachment or filter screen in the peripheral edge region or in the region of the projection.

For this purpose, it is particularly advantageous if the stiffeners in the peripheral edge region over the circumference are preferably evenly spaced and aligned radially or radially.

In this case, a particularly advantageous and preferred embodiment according to the invention provides that the stiffeners run in the peripheral edge region from the peripheral edge to the projection and / or are designed as a cross-sectional thickening.

The projection can not only be designed as a projection formed approximately centrally on the peripheral edge region, but rather it is also possible for the projection to be formed from radially mutually and / or centrally arranged wall sections. Such a lead, in particular if it is not intended additional filter function, can still be made sufficiently stable, even with a comparatively small cross-section.

In this case, it is particularly advantageous if the cross-sectional thickenings forming the stiffeners in the peripheral edge region merge into the wall sections of the projection.

The inventively provided attachment or filter screen 10 can be produced easily and inexpensively, when the projection is integrally connected to the peripheral edge region of the particular designed as a plastic injection molded part Vorsatzoder filter screen.

Preferred developments according to the invention provide that the sanitary insert part has a jet regulator, flow rate regulator and / or backflow preventer or is designed as such.

It is particularly advantageous if the attachment or filter screen has its peripheral edge in a recess provided on the inflow-side end face of the insert part

, can be screwed, latched or detachably fastened by means of a plug-in rotary connection.

25

An expedient embodiment of the invention can provide that the attachment or filter screen with the inflow-side end face of the insert part encloses a receiving space in which a flow rate regulator or a flow restrictor

30 or another built-in part is detachably arranged or connected. The releasable assembly may be achieved, for example, by insertion or insertion, while a releasable connection may provide additional attachment means. Thus, the screen by means of the handle is not only for

35 cleaning purposes of the screen quickly and easily removable and re-mountable, but it is also possible by means of the handle, mounting parts, which are located between the front screen and the jet regulator housing comprehensive insert part, either or easily depending on the type of use or insert. In particular, a user of the insert with handle by just this handle receives the indication that the front screen is removable and is thus led to the possibility to provide an unsupported performance of the insert additionally an Embauteil or to remove such. For example, loosely inserted flow regulators or flow throttles or throttling disks which can be used detachably attached to the jet regulator and which have the function of throttling the flow at higher pressures either proportionally to the pressure or independently of the pressure on one are preferably usable as the mounting part constant value.

Such flow-regulating or flow-throttling properties of a jet regulator are sensible and necessary, in particular at high network pressures, in order to save water and energy and to allow the water jet to emerge comfortably and not spurting. In areas where there is a very poor pressure supply or m areas where the sanitary water pressure is based solely by geodetic height difference to a usually located on the house roof water tank is usually a jet regulator of other construction type, the lowest possible intrinsic resistance against the water flowing through, required, because this self-resistance leads to additional pressure losses and thus the flow is too low to have comfortable use properties. But one uses such designed for low pressure applications jet regulator m applications in which a customary sanitary pressure between 1 and 6 bar Due to the low intrinsic resistance, this leads to extreme water consumption and an uncomfortable water jet, which splatters very strongly. Since the pressure conditions in a domestic sanitary installation can be very different from home to house, it is impossible for the supplier of jet regulators and / or fittings to predict beforehand which embodiment of the jet regulator is right for the customer's specific pressure conditions. In particular, when the pressure supply varies from apartment to apartment within a house, because individual pressure-generating, supporting pumping systems are installed, a flexible adjustment of the jet regulator, as the invention provides, is advantageous. The invention offers in particular the possibility that when installing the valve or when installing the jet regulator depending on the pressure prevailing at the installation of the installer or even the user can decide without expert knowledge, whether he has a flow rate controller or a flow restriction of functional or needed or not energetic. In the event that the pressure conditions are low or decrease over time or the user does not want volume control or restriction by a limiter or other built-in part, he can easily remove the inserted components without tools by means of handle on the front screen.

A further embodiment of the invention can provide that a receiving space between intent or filter screen and inflow-side end face with defined dimensions can be formed by a direct connection of the attachment or filter screen with the insert, ie by a connection without additional intermediate part or at least without participation of the insert is. Thus, by inserting an additional built-in part of the overall height, so the dimensions Solution of the insert with attached attachment or filter in the axial direction, not enlarged. The receiving fitting can therefore be provided with a uniform recess.

It is true that EP 0 733 748 B1 discloses an Embauteile-Garmtur in which a jet regulator, a front screen and a flow rate regulator is provided, the attachment of the flow rate regulator and the front screen being mutually compatible, so that either the flow rate regulator with the Attachment strainer or the attachment strainer can be attached directly to the jet regulator, but the additional flow regulator leads to an increase in overall height and a very sharp screwdriver or knife is required to remove the strainer or remove the flow regulator to solve. In addition, the flow regulator must be elaborately designed to keep the strainer safe and to provide sufficient stability.

On the other hand, the invention offers the advantage on the one hand that the end user now directly perceives the option of omitting the flow rate regulator, since he receives an indication from the handle on the component to be able to remove a part. On the other hand, the tool-free, manual disassembly of the attachment or filter damage to the very thin-walled and filigree intent or filter screen or the flow regulator is practically impossible. Also, the front screen is easier to produce with the invention, for example as a one-piece plastic injection molded part.

It may be advantageous if the attachment or filter screen on the downstream side of a preferably pin-shaped and / or preferably projecting into the receiving space centering has, which engages in a recess of the flow rate regulator or throttle plate and this centers and / or leads and / or axially fixed.

According to a further embodiment of the invention, the flow rate regulator or the flow restrictor is disk-shaped and it is the radial dimension of the flow rate controller or the flow restrictor determines the diameter of the passage openings forming plate or plate-shaped peripheral edge region. Thus, the flow regulator or the flow restrictor covers the area in which the passage openings of the filter or attachment screen are formed in the peripheral edge region. In addition, the built-in part, ie the flow rate regulator or the flow restrictor or a further part, can thus be placed in a receptacle of the insert part into which the filter or attachment screen also fits. The built-in part is thus radially fixed by this recording. The flow rate regulator or the flow throttle is preferably loosely inserted into a recess formed on the upstream face of the insert part and at least axially fixed by the attachment or filter screen, which is preferably releasably connected to the insert part, and can therefore be easily removed or replaced without the use of tools.

In the invention, a flow rate regulator can be used in an advantageous manner, which has a deformable ring on the inflow side, which presses against a preferably knob-shaped contour of the flow rate regulator by applying pressure. The ring is elastic and presses radially against the knob-shaped contour. Such a designed flow regulator is inexpensive to manufacture and robust and has a long life. The flow regulator is preferably made of two plastic pieces with separate rubber or silicone ring. In the invention is further advantageous as a built-in part designed as a one-piece perforated disc with one or more holes throttle disc usable. This throttle plate can be used in addition to the flow regulator or instead of the flow regulator.

It is particularly favorable if at least two flow rate regulators for respectively different flow rates and / or at least two throttle disks for different pressure differences can be used optionally and / or are provided so as to be interchangeable. Thus, the insert is individually customizable to the different pressure conditions and / or flow rates on site. For the replacement of the various built-in parts, in particular the flow rate regulator and / or the throttle disks with each other, the different built-in components are advantageously held or kept ready.

In one embodiment of the invention it can be provided that the attachment or filter screen is made of a transparent or translucent material. Thus, it is directly visible to a user even when assembled insert part, whether a built-in part is present or not. It is particularly advantageous if the flow rate controller or the flow restrictor or the other built-in component is color-coded in contrast to the insert part. Here, red, green, blue, yellow, white, black or mixed colors or metallic colors can be used with advantage. The colorations advantageously encode different flow rates and / or pressure differences and stand out from the insert part. A user can thus immediately recognize with attached attachment or filter, which built-in part is used and / or which flow rate limitation is provided. In one embodiment of the invention it can be provided that the flow rate regulator or the flow restrictor or the further built-in part has a region which differs in color from the upstream end face or a wall of the receiving space of the insert. The area is preferably visible through a transparent or translucent intent or filter screen in the inserted position in the receiving space. A particularly simple embodiment results when the flow rate controller or the flow restrictor or the further built-in part is made as a colored injection-molded part.

Further embodiments according to the invention will become apparent from the claims and the drawings.

The invention will be described in more detail below with reference to preferred exemplary embodiments.

It shows :

1 is a designed as a jet regulator sanitary insert part in a perspective view, wherein the insertion part on the inlet side a Vorsatzoder filter is assigned, on which a serving as a handle and projecting from radially arranged wall portions projecting projection in the inflow direction,

2 shows a likewise shown in a perspective Dar- position and equipped with an attachment or filter insert insert, the intent or filter screen is configured here as a cylindrical and closed at the free end end hollow body having additional filter openings, FIG. 3 shows the unit already shown in FIG. 2 and consisting of insert part and filter screen in a perspective partial cross-sectional view, whereby this unit is inserted here into the outlet mouthpiece of a sanitary outlet fitting, FIG.

Fig. 4 shows another designed as a jet regulator insert part in a perspective view with attached filter screen and

Fig. 5 shows the insert part of Fig. 4 in a perspective view with removed filter screen and inlaid flow regulator.

1 to 3, a sanitary insert part 1 is shown, which is designed here as a jet regulator and in particular as a jet aerator. The insert part 1 can be used in a water pipe and, if necessary, arranged in a removable manner. From Fig. 3 it is clear that the insert part 1 can be used here in an outlet nozzle 2, which can be releasably attached to the water outlet of a sanitary outlet fitting 3.

Since the sanitary insert part 1 can be impaired in its function by the dirt particles possibly contained in the inflowing water flow, a filter or attachment screen 4, 5 is arranged upstream of the insertion part 1 in the flow direction. So that the unit consisting of filter sieve 4 or 5 and insert part 1 is not unintentionally released during storage, transport or assembly and the insert part 1 is installed without the filter screen 4 or 5 by mistake, the filter screen 4, 5 is on the inflow-side end face of the insert part 1 releasably attachable. The filter screen 4 or 5 is for this purpose in a ner provided on the inflow-side end face of the insert part 1 recess 6 and held there by means of a provided between the peripheral edge of the filter screen 4 and 5 and the inner circumference of the recess 6 Rastverbin- düng.

In order to solve the filter screen 4 or 5 quickly and easily without tools and destructive from this locking connection and if necessary so remove from the insert part 1, that the filter screen 4 and B can then also be reused resource saving, stands on the inflow side of the filter screen 4, 5, a projection 7 or 8 before, which is designed as a handle.

It can be seen from FIGS. 1 to 3 that the filter screen 4 or 5 has a plate-shaped circumferential edge region 9 tapering conically in the flow direction and delimiting the centrally arranged projection 7 or 8. In order to be able to stiffen the material of the filter screen 4 or 5 weakened in the region of flow openings 10 and 11 so that the filter screen 4, 5 can be released from its detent connection, for example by tilting movements, the filter screen 4, 5 in FIGS its peripheral edge region 9 flow-opening-free ribs or the like stiffeners 12. These stiffeners 12 are uniformly spaced in the peripheral edge region 9 over the circumference and aligned radially or radially.

In the case of the filter screen 4 shown in FIG. 1, these stiffeners 12 are additionally designed as cross-sectional thickenings which merge into a projection 7, which is formed from radially arranged wall sections 13.

While the projection 7 of the filter shown in FIG. siebes 4 only serves as a handle, the projection 8 of the shown in FIGS. 2 and 3 filter screen 5 is still an additional filter function intended. The projection 8 of the filter screen 5 is designed as a cylindrical and closed at its free inflow end face 14 hollow body. The filter screens 4, 5 have flow openings 10 at their peripheral edge areas. The filter screen 5 additionally has flow openings 10, 11 on the free end face 14 and on the circumferential wall of its projection 8, as a result of which the filter surface is substantially enlarged. While the flow openings 10 provided on the peripheral edge regions 9 of the filter screens 4, 5 and on the free end face 14 of the projection 8 arranged on the filter screen 5 have a honeycomb-shaped clear cross section, the projections on the circumferential wall of the projection shown in FIGS 8 arranged flow openings 11 designed slit-shaped.

The projection 7, 8 of the filter foils 4, 5 preferably formed of plastic injection molded part is integrally formed on the peripheral edge region 9, wherein the protrusion 8 designed as a hollow body in FIGS. 2 and 3 is designed to be open towards its downstream end side.

In Fig. 3 it can be seen that the projection 8 of the Filterie- bes 5 is adapted in shape in its cross section to the clear cross-section of the upstream in the inflow direction of the insert part 1 line section. In this case, the outer circumferential wall forming the projection 8 is arranged at a radial distance from the inner peripheral wall of the inner wall of the outlet formed by the water outlet of the outlet fitting, so that the inflowing water flow can flow around the entire inflow-side surface of the filter screen 5. 4, a filter screen 4 is arranged on the inflow-side end face and inserted into a recess formed on this end face. The filter screen 4 has a handle 7, which is formed of radially or star-shaped composite, mutually cutting centrally wall portions 13, each describing an axis of symmetry of the insert, so the axial direction, comprehensive level. These wall sections 13 run outward in the radial direction into stiffeners 12, which subdivide and reinforce the plate-shaped peripheral edge region 9 m segments. The arrangement of the wall sections 13 and the formation of the insert part 1 have a total of six-fold rotational symmetry about the axial direction, but in other embodiments, other, in particular discrete, rotational symmetries, such as bizarre, drezzigeige, fourfold, fünfzählige or achtzählige symmetries realized. In the peripheral edge region 9 honeycomb flow openings 10 are formed and arranged in a grid, whereby a sieve is formed. At the periphery or edge of the peripheral edge portion 9, a ring 15 is formed for reinforcing the edge. In the ring 15 recesses 16 are formed, the m Fig. 5 shown in detail latching lugs for fixing or attachment of the filter screen 4 on the insert part 1 record.

FIG. 5 shows the insert part 1 with the filter sieve 4 removed. On the radial edge of the stiffeners 12, latching lugs 17 are formed, the groove-shaped recesses 18 in the brim 19 of the insert part 1 in the position of use m lock. The brim 19 ensures a radial alignment of the filter screen 4 with respect to the insert part 1, while the latching lugs 17 effect an axial fixation. The inflow-side end face 20 of the insert part 1 has flow openings 27 through which the inflowing water passes into the jet regulator. This end face 20 forms with the protruding brim 19 a receiving area 21 into which the filter screen 4 is inserted. In the position of use, ie in the inserted position, the ring 15 is in contact with the insertion part 1, and the locking lugs 17 engage with the groove-shaped recess 18. By the conical or funnel-shaped shape of the filter forming peripheral edge portion 9 and the flat design of the inflow-side end face Thus, in the position of use of the filter sieve and the insert part in the receiving region, a receiving space is enclosed in the insertion part 21, in which the flow rate regulator 22 or another component approximately corresponding to its external dimensions to the flow rate regulator 22 can be inserted. The flow rate regulator 22 is thus disk-shaped and has a diameter which fits into the receiving area 21, whereby the flow rate regulator 22 is held virtually without radial play.

The flow rate regulator 22 has on the inflow side a receptacle 23 into which a peg-shaped projection 24 of the filter screen 4 arranged centrally on the outflow side engages for fixing, centering and / or guiding the flow rate regulator 22. This projection 24 is arranged m the axial extension of the section line of the wall portions 13. The flow rate regulator thus has no fastening means itself, but is held and guided by the brim 19, the filter screen 4 and the end face 20. On the upstream side of the flow rate controller 22, a circumferential, elastically deformable ring 25 is formed, which is surrounded by arranged on a concentric circle to the symmetry circle nubs 26. Between the nubs 26 of the flow rate controller 22 is broken in the axial direction. Under the pressure of the flowing liquid is the elastic Rxng 25 axially compressed and deforms radially into the intermediate spaces between the nubs 26, whereby the free passage area for the liquid is limited.

The recess 23 is designed in an additional embodiment as an open passage and thus forms a bypass to flow rate regulation.

An orifice plate likewise provided for installation in the receiving space differs from the illustrated embodiment of a flow rate regulator 22 by a fixed geometry, which is preferably formed by a one-piece plastic injection molded part, for example with many small individual holes or one large passage.

In a further embodiment, the filter screen 5 of FIG. 2 is inserted instead of the filter screen 4 shown in FIGS. 4 and 5 in the recess 21 of Emsetzteil 1 of Fig. 4 and 5, and the insert is as described in Fig. 5 between filter 5 and insert part 1 is arranged.

Preferably, the filter screen 4 in FIG. 5 is made of a transparent or translucent material, and the fitting to be replaced or removed, that is, for example, the flow rate regulator 22 or a

Throttle plate is color in contrast to Emsetzteil 1 characterized, so for example manufactured as a colored injection molded part or has a colored element or a colored area, wherein the color of the

Color of the inner wall of the receiving space for the insert forming recess 21 distinguishes and lifts. By such a combination of transparent or translucent filter screen 4 and color-coded mounting part can the user can easily see whether in the flow direction behind the filter screen 4, so for the viewer of the composite insert 1 under the assembled filter screen 4, a built-in part and if so, which color this built-in has. In particular, the color of the built-in component, that is to say the color of the flow rate regulator 22 in FIG. 5, differs from the color of the inflow-side end face 20 of the insert part 1 and / or from the color of the rim forming a ring flange 19.

The invention relates to a sanitary insert part which can be used in a water pipe and, if necessary, removably arranged and at its inflow-side end face with a filter or attachment screen is detachably connected. It is characteristic of the present invention that a projection formed as a handle projects for the purpose of tool-free disassembly on the inflow side of the filter or front screen. The inventively provided filter or attachment screen of the insert is characterized by the fact that it can be quickly and easily destructively separated and removed from the insert part as needed. By manually disassembling the filter or attachment screen used, a receiving space for a flow rate regulator or a flow restrictor is easily accessible.
