Definitions

  • the invention relates to a shower head with a shower head housing, a fluid inlet into the shower head housing, a shower jet outlet from the shower head housing, a fluid guide in the shower head housing from the fluid inlet to the shower jet outlet, and a pressure relief valve coupled to the fluid guide with a movable valve body which is located at an overpressure in the Fluid guide moved from a normal position to an overpressure position.
  • overpressure means a pressure that is above a normal pressure range, in which the fluid pressure in the fluid guide in normal operation when the shower head is used as intended and functions properly, taking into account normal pressure fluctuations, e.g. lies in an upstream fluid supply.
  • these shower heads have a pressure relief valve which responds to an overpressure in the fluid guide in the shower head housing in order to avoid prolonged operation of the shower head in such a pressure condition.
  • the pressure relief valve is pressure-coupled to the fluid guide, that is to say coupled in terms of pressure technology, so that the excess pressure in the fluid guide acts on the pressure relief valve and moves its movable valve body into the pressure relief position.
  • the valve body is in its normal position, ie its position intended for the normal shower operation of the shower head.
  • a ring provided with an annular groove, preferably with a substantially V-shaped cross section, is provided between an outlet-side spray disc, which is provided in the usual manner with a plurality of spray outlet openings, and an adjacent part of the shower head housing in a free annular gap, the additional outlet cross section is formed in the form of openings arranged at the bottom of the annular groove, which are closed by an elastic sealing ring, such as an O-ring, which expands elastically in the fluid guide in the shower head housing when there is excess pressure, thereby opening up the otherwise closed openings.
  • an elastic sealing ring such as an O-ring
  • a pressure relief valve is provided with a valve body which is arranged centrally and axially movable on the shower head and in the normal position is approximately flush with a spray disc, while it protrudes somewhat in the pressure position.
  • the pressure relief valve has a leakage opening leading from the fluid guide to the jet disc, which is closed in the normal position by the movable valve body and released when an overpressure occurs.
  • the valve body is biased into its closed position by means of a biasing spring.
  • the invention is based on the technical problem of providing a shower head of the type mentioned at the outset, which offers improvements over the prior art mentioned above, in particular with regard to functionality with regard to the overpressure behavior.
  • the invention solves this problem by providing a shower head with the features of claim 1.
  • the valve body in the overpressure position is designed to be self-retaining and operated by the user and can be moved back into the normal position.
  • self-holding is the property of Valve body means that if it has reached its overpressure position due to an overpressure in the fluid guide, it will remain in this position even if the overpressure in the fluid guide no longer exists.
  • the return movement of the valve body from its overpressure position to its normal position is user-operated and therefore not automatic. This gives the user the opportunity to first clarify the cause of the excess pressure and, if necessary, to clean the shower head, in particular the shower jet outlet, if the excess pressure is caused by dirt particles and / or calcifications, as can often be found especially at the shower jet outlet. The user can then move the valve body back from its overpressure position to its normal position, so that the shower head is again in its normal operating state.
  • the valve body acts in a position-dependent manner on a passage cross section of the fluid guide, wherein it reduces the passage cross section in the overpressure position compared to the normal position.
  • the pressure relief valve does not provide for the release of an additional pressure relief opening or the corresponding increase in the overall fluid outlet cross section of the shower head in the case of overpressure compared to normal operation, but for a reduction in the passage cross section of the fluid guide from the fluid inlet to the shower spray outlet. This reduces the volume flow of fluid passed through the shower head.
  • the volume flow reduction can be so strong, for example, that the fluid only exits the shower head in individual drops. This prompts the user to intervene or maintain the shower head.
  • the invention reliably and reliably avoids in each of its aspects mentioned that the shower head is operated in the shower head housing with excessive pressure for a long time.
  • the shower jet outlet contains a plurality of jet outlet openings
  • the fluid guide has a distribution chamber upstream of the jet outlet openings.
  • the valve body acts on the passage cross section of the fluid guide between the fluid inlet and the distribution chamber. The valve body can thereby reduce the passage cross section of the fluid guide at this point, if an overpressure occurs in the fluid guide, whereby the volume flow of fluid into the distribution chamber can be reduced. This allows the overpressure in the distribution chamber to be reduced via the jet outlet openings and the reduced volume flow to indicate to the user that there is an overpressure case.
  • the valve body is cylindrical and movable in the axial direction in the shower head housing and has a radially projecting ring collar with at least one valve passage opening.
  • the fluid guide comprises a valve chamber in which the valve body with its ring flange is guided in an axially movable manner, as well as at least one valve inlet opening opening into the valve chamber and at least one valve outlet opening opening out of the valve chamber. With its ring collar, the valve body reduces a passage cross section of the at least one valve outlet opening in the overpressure position compared to the normal position.
  • the ring collar thus serves in this embodiment as a kind of movable valve closing body, which leaves the at least one valve outlet opening free when the valve body is in its normal position, and the valve outlet opening at least partially, i.e. completely or partially, blocked or closed when the valve body is in the overpressure position.
  • the at least one valve inlet opening extends axially, as does the at least one valve passage opening. In the normal position of the valve body, the valve passage opening is aligned with the valve inlet opening. This represents a constructively and fluidically advantageous realization for the fluid guidance in this area.
  • the shower head in the shower head housing contains a hollow cylindrical valve seat body, on which the valve body is held in a guided manner and in which the valve chamber is located.
  • the at least one valve outlet opening extends with a radial directional component, optionally additionally with an axial directional component, through a cylinder jacket section of the valve seat body.
  • the shower head contains a jet disk forming the shower jet outlet, and the valve body is located on the same side of the shower head housing as the jet disk. Since the spray disc side of a shower head usually represents that side of the shower head which faces the user in operation or which he can easily see in any case and which is easily accessible for him, this measure has the advantage that the user has the valve body and its respective current position recognize it well and if necessary, e.g. for moving back from its overpressure position to its normal position, can be easily handled.
  • the valve body projects from the outside of the jet disk in the overpressure position, while it does not project from the outside of the jet disk in the normal position, i.e. is aligned with it or alternatively is set back relative to it.
  • the user can very easily recognize from the position of the valve body relative to the spray disc whether there is an overpressure drop or not.
  • the pressure relief valve comprises a magnet arrangement which holds the valve body in the normal position by a magnetic force, the magnetic force being able to be overcome by an overpressure in the fluid guide, but not by the pressure forces of any normal fluid pressure fluctuations in the fluid guide in the normal, error-free manner Operation of the shower head.
  • the strength of the magnetic force decreases with increasing distance of the valve body from the normal position to an irrelevance value in the overpressure position.
  • the term irrelevance value means that the value of the magnetic force in the overpressure position is zero or in any case so low that the magnetic force is then no longer able to remove the valve body automatically by overcoming the usual frictional forces and any remaining fluid pressure forces To move the overpressure position back to its normal position when the overpressure drop is no longer present, ie the overpressure in the fluid guide has been reduced.
  • the magnetic force has no relevance for the return movement of the valve body from its overpressure position to the normal position. The user can therefore decide for himself when he wants to move the valve body back to its normal position, for which he accordingly can operate. In the normal position, the valve body then holds again through the action of the magnetic force.
  • the shower head shown comprises a shower head housing 1, a fluid inlet 2 into the shower head housing 1, a shower jet outlet 3 from the shower head housing 1, a fluid guide 4 in the shower head housing from the fluid inlet 2 to the shower jet outlet 3 and a pressure relief valve 5.
  • the pressure relief valve 5 is pressure-coupled to the fluid guide 4, ie a fluid pressure which prevails in the fluid guide 4 in a corresponding area to which the pressure relief valve 5 is operatively coupled acts on the pressure relief valve 5 1 and 2 built-in pressure relief valve 5 is in the 3 to 7 illustrated in more detail. It is understood that this pressure relief valve can also be used in other shower heads.
  • the pressure relief valve 5 contains a movable valve body 6 which, in the event of an overpressure in the fluid guide 4, changes from a normal position N S , as shown in FIGS 3 to 5 is shown, moved to an overpressure position U S , as in the 6 and 7 and in the installed state of the 1 and 2 is shown.
  • the valve body 6 is designed such that it remains self-holding in the overpressure position U S and can be moved back to the normal position N S when operated by the user. This means that the valve body 5, if it has assumed its overpressure position due to an overpressure in the fluid guide 4, remains in the overpressure position U S until the user moves it back into the normal position N S , even if in the meantime the overpressure in the fluid guide 4 is no longer available.
  • the pressure relief valve 5 has a magnet arrangement 7 for this purpose, which holds the valve body 6 in the normal position N S by a magnetic force F M that can be overcome by an excess pressure from the fluid guide 4, the strength of the magnetic force F M also increasing distance of the valve body 6 from the normal position N S to an irrelevance value in the overpressure position U S decreases.
  • the pressure relief valve contains, instead of such a magnet arrangement, another conventional holding force source, which acts on the valve body in the normal position N S with a holding force which can be overcome by the excess pressure in the fluid guide 4 and which no longer acts on the valve body 6 in the pressure position U S, or in any case is not so strong that it could move the valve body 6 back to the normal position N S even when the excess pressure is no longer present.
  • another conventional holding force source which acts on the valve body in the normal position N S with a holding force which can be overcome by the excess pressure in the fluid guide 4 and which no longer acts on the valve body 6 in the pressure position U S, or in any case is not so strong that it could move the valve body 6 back to the normal position N S even when the excess pressure is no longer present.
  • the magnet arrangement 7 is formed by two interacting magnets 7a, 7b, of which a first magnet 7b is arranged in or on the valve body 6 and a second magnet 7a in or on a part of the pressure relief valve 5 which remains stationary.
  • the two magnets 7a, 7b can, for example, be permanent magnets and provide the magnetic force F M as a magnetic attraction between the two magnets 7a, 7b, which, as usual, rapidly decreases in strength with increasing distance between the two magnets 7a, 7b.
  • the magnets 7a, 7b are suitably chosen so that in the normal position N S of the valve body 6, in the they have their smallest distance, the magnetic force F M in the strength required to hold the valve body 6 in its normal position N S provide, while the magnetic force F M in the overpressure position U S of the valve body 6, in which the two magnets 7a, 7b their maximum Have distance, has practically dropped to zero or in any case so far that it is no longer able to move the valve body 6 back to the normal position N S against any frictional forces and any fluid pressure forces that may be present.
  • valve body 6 acts in a position-dependent manner on a passage cross section D Q of the fluid guide 4 in such a way that it reduces the passage cross section D Q in the overpressure position U S compared to the normal position N S.
  • the valve body 6 is cylindrical and movable in the axial direction A R in the shower head housing 1, the axial direction A R as usual being understood to mean the direction parallel to a longitudinal center axis of the cylindrical valve body 6, as well as its opposite direction.
  • the valve body 6 has a radially projecting ring collar 8 with at least one valve passage opening 9.
  • the fluid guide 4 comprises a valve chamber 10, in which the valve body 6 is movably guided with its ring collar 8.
  • the fluid guide 4 has at least one valve inlet opening 11 opening into the valve chamber 10 and at least one valve outlet opening 12 opening out of the valve chamber 10.
  • the valve body 6 With its ring collar 8, the valve body 6 reduces the passage cross section D Q of the at least one valve outlet opening 12 when the valve body 6 is in the overpressure position U S , compared to the operating state when the valve body 6 is in the normal position N S. In other words, in the example shown, the valve body 6 reduces the passage cross section D Q of the fluid guide 4 in the region of the at least one valve outlet opening 12. In alternative embodiments, the valve body acts at another point on the fluid guide 4 on its passage cross section D Q in the sense of a reduction when excess pressure occurs a.
  • the reduction can be that the passage cross-section D Q is completely blocked, ie reduced to zero, or alternatively to a desired other reduced cross-sectional value between the value zero and a maximum value that the Passage cross section D Q has at the relevant point of the fluid guide 4 when the valve body 6 is in the overpressure position U S.
  • valve chamber 10 the at least one valve inlet opening 11 and the at least one valve outlet opening 12 can e.g. all be formed on the pressure relief valve 5.
  • the valve chamber 10 is of annular cylindrical shape, alternatively it can have another shape, e.g. a fully cylindrical shape.
  • a plurality of valve inlet openings 11 and valve through openings 9 are provided, e.g. each arranged equidistantly in the circumferential direction.
  • both the at least one valve inlet opening 11 and the at least one valve passage opening 9 purely axial, ie parallel to the axial direction A R, wherein the at least 9 in alignment with the at least extends to a valve passage opening a valve inlet port 11 when the valve body 6 in the normal position N S is located.
  • the at least one valve inlet opening and / or the at least one valve passage opening runs at least in sections at an angle or perpendicular to the axial direction A R. The flush transition from the respective valve inlet opening 11 to the respective valve passage opening 9 enables the fluid to pass through the at least one valve inlet opening 11 into the valve chamber 10 through the at least one valve passage opening 9 in the normal position N S of the valve body 6.
  • valve body 6 lies in the normal position N S with its respective valve passage opening 9 with no or at most a short distance from the respective valve inlet opening 11 in an associated end region of the valve chamber 10.
  • the valve body 6 with its ring collar 8 is located in the other end region of the valve chamber 10 and consequently at a noticeable distance from the valve inlet opening (s) 11, so that the one or more valve inlet openings 11 are not blocked off by the valve body 6 even in the event of overpressure.
  • the pressure relief valve 5 contains a hollow cylindrical valve seat body 13, on which the valve body 6 is held and in which is the valve chamber 10.
  • the at least one valve outlet opening 12 with a radial directional component extends outward through a cylinder jacket section 13a of the valve seat body 13.
  • the valve seat body 13 is made from several assembled parts, in alternative versions it is made in one piece. In the example shown, it is provided in an end region with an external thread 14 with which it can be screwed into an internal thread of an articulated sleeve 15 of the shower head 1, as shown. Furthermore, in the example shown, the valve seat body 13 has an external thread 16 in an axially central region, to which a shower outlet part 1 a of the shower head housing 1 is screwed. In alternative embodiments, the valve seat body 13 can be connected to the shower head housing in another conventional manner.
  • the shower outlet part 1a is made in a flat shower design, which means that the shower head is 1 and 2 Particularly suitable as a flat overhead shower, as is known per se for use in sanitary shower rooms or shower facilities.
  • the shower outlet part 1 a is articulated via a ball joint 16 to a shower head connection part 1 b, via which the shower head can be connected to a fluid supply and which forms the fluid inlet 2.
  • the shower head is not configured in this flat design, but of another conventional design, for example a bell-shaped design.
  • a sieve element 17 is optionally arranged as a dirt / particle sieve in the fluid guide section of the shower head connection part 1b between the fluid inlet 2 and the at least one valve inlet opening 11.
  • the shower outlet part 1a has, apart from the pressure relief valve 5, a structure which is known per se and which ends on the fluid outlet side with a jet disk 18 which forms the shower jet outlet 3 and which is provided with one or usually a plurality of jet outlet openings 19 which, in a predeterminable configuration, have a circular or square shape, for example Exit surface of the jet disc 18 are arranged away.
  • the fluid guide 4 as in the example shown, has a distribution chamber 20 upstream of the jet outlet openings 19, from which the jet outlet openings 19 open and into which the at least one valve outlet opening 12 opens.
  • the valve body 6 thus acts on the passage cross section D Q of the fluid guide 4 between the fluid inlet 2 and the distribution chamber 20, here specifically between the valve chamber 10 and the distribution chamber 20.
  • valve body 6 is located on the same side of the shower head housing 1 as the spray disc 18 forming the spray spray outlet 3. In the exemplary embodiment shown, the valve body 6 is specifically located in a central region of the spray disc 18. In alternative embodiments, the valve body 6 is in relation to the spray disc 18 arranged off-center.
  • the valve body 6 projects from the outside of the jet disk 18 in the overpressure position U S.
  • the shower head is in the 1 and 2 shown.
  • the valve body 6 does not protrude from the outside of the spray disc 18, ie it is positioned in a recessed manner in the interior of the shower head housing 1 or is essentially flush with the outside of the spray disc 18.

  • a center pin 13c is formed on the valve seat body 13, which delimits the annular valve chamber 10 radially inward and can act as an additional guide for the valve body 6, for which purpose the valve body 6 in an associated section 6c axially between its ring collar 8 on the foot side and a head section 6b, which ends with the outside 6a, is designed to be correspondingly hollow-cylindrical.
  • a pressure channel 21 is formed which is in fluid communication with the valve chamber 10 and leads axially forward to an end face 22 of the valve body head section 6b.

  • a plurality of valve outlet openings 12 are provided equidistantly distributed in the circumferential direction.
  • the number of valve outlet openings 12 may correspond to the number of valve through openings 9 or be different from this.
  • valve body 6 with its ring collar 8 is located on the inner or rear, ie upper, end area of the valve chamber 10 in the figures, the respective valve passage opening 9 being flush with the associated valve inlet opening 11 and the pressure channel 21 opening in this area.
  • the valve outlet openings 12 are completely released without the valve body 6 having the passage cross section D Q determined by the overall configuration of the shower head Fluid guide 4 limited.
  • fluid supplied via the fluid inlet 2 consequently reaches the shower jet outlet 3 via the fluid guide 4, where it emerges as a corresponding shower jet. More precisely, the fluid flows here via the valve inlet openings 11 and the valve passage openings 9 into the valve chamber 10 and from there via the valve outlet openings 12 into the distribution chamber 20, from where it distributes itself onto the jet outlet openings 19.
  • an overpressure occurs in the fluid guide 4, for example in the distribution chamber 20, this leads to a corresponding overpressure in the valve chamber 10 of the overpressure valve 5 pressure-coupled to the fluid guide 4.
  • the overpressure in the valve chamber 10 also pushes the fluid into the pressure channel 21, as a result of which presses the fluid with the corresponding overpressure against the end face 22 of the valve body 6.
  • the magnet arrangement 7 is designed in such a way that the magnetic force F M it provides in the normal position N S of the valve body 6 is smaller than the oppositely acting fluid overpressure force that the fluid under pressure on the valve body 6 exerts on its end face 22.
  • valve body 6 detaches itself from the normal position N S against the magnetic force F M and moves axially forward or outward following the fluid overpressure force, ie downwards in the figures, up to its overpressure position U S , which is opposite the normal position N S Represents end position of the valve body 6.
  • This extension movement of the valve body 6 against the magnetic force F M and against any frictional forces and against the ambient pressure acting on the outside 6a of the valve body 6 can additionally be supported by an entraining effect of a residual flow of fluid in the valve chamber 10 if the system is designed accordingly.
  • the pressure relief valve 5 also responds when the shower head is connected to a fluid supply whose fluid supply pressure is greater than that for which the shower head is designed.
  • the valve body 6 In the overpressure position U S, the valve body 6 with its ring collar 8 completely or alternatively partially blocks the respective valve outlet opening 12, as is shown, for example, in FIGS Fig. 2 and 5 can be seen.
  • the valve body 6 in this overpressure position U S reduces the passage cross section D Q of the fluid guide 4 at this point to zero or in any case to a lower value than the effective passage cross section of the fluid guide 4 in normal operation.
  • the consequence of this is that the volume flow of the fluid at the shower outlet 3 is correspondingly reduced. This can easily be recognized by the user by the fact that the shower jet stops or the shower head at the shower outlet 3 only drips.
  • the user can recognize the overpressure case that has occurred because the valve body 6 has moved into its extended overpressure position U S and therefore projects forward or outward from the outside of the jet disk 18.
  • the valve body 6 can be made at least in its area protruding from the jet disk 18 in a color contrasting from the surrounding jet disk area. This can make it even easier for the user to recognize that the pressure relief valve 5 has responded.
  • the fluid can no longer flow or at least no longer flow into the distribution chamber 20 in a significant amount, so that any excess pressure initially present there due to the escape of the remaining fluid Can remove shower outlet 3.
  • the user can now take the necessary measures For example, clean the shower head as a whole or at least at the shower outlet 3, ie eliminate the cause of the overpressure that has occurred.
  • the valve body 6 initially remains in its overpressure position U S , since the two magnets 7a, 7b are now so far apart that they no longer exert any or any significant magnetic force on the valve body 6, ie the magnet arrangement 7 is not able to withdraw the valve body 6 automatically into the normal position N S.
  • valve body 6 After the user has eliminated the cause of the excess fluid pressure, he pushes the valve body 6 back into its normal position N S , for example by pressing with a finger against the outside 6a of the valve body 6.
  • the valve body 6 in the example shown forms with its head section 6b a valve pin, which the user can push back from the extended overpressure position U S to the retracted normal position N S.
  • the magnet arrangement 7 then holds the valve body 6 in its normal position N S with its magnetic force F M.
  • the valve body 6 in the normal position N S completely clears the passage cross section D Q of the fluid guide 4, in the example shown by completely clearing the valve outlet openings 12. The shower head is thus ready for use again.
  • the invention provides a shower head with an advantageous pressure relief valve function. Damage to the shower head can be avoided by the integrated pressure relief valve.
  • the pressure relief valve can ensure a reduction in the fluid volume flow, so that the excess pressure can be reduced by the remaining leakage of fluid from the shower head, preferably via the shower jet outlet, without fluid escaping at the pressure relief valve itself.
  • the user can easily recognize an overpressure case, eliminate the causes of the overpressure and then bring the valve body back from its overpressure position to its normal position under its own control.
  • the shower head according to the invention can be used both for any types of sanitary showers and for non-sanitary showers, if and to the extent There is a need to protect the shower head from any fluid overpressure in the fluid guide.
