Definitions

  • the invention relates to a sanitary insert part with an inlet side and an outlet side, wherein a securing means is formed between the inlet side and the outlet side, wherein the securing means is designed to be detachably secured to a counter securing means on a water outlet of a sanitary fitting, wherein a seal element is formed between the securing means and the inlet side, creating an at least partial seal; and with a jet aeration device which has an aeration access point that is open towards the outlet side.
  • the invention further concerns an outlet assembly, comprising an insert part as described above, which is inserted into the water outlet of a sanitary fitting, wherein a seal element at least partially seals an aperture between the insert part and the water outlet.
  • the invention finally concerns the use of a discharge opening connected to a jet aeration device.
  • the opening allows for a reduction in leachate escaping between the insert and a water outlet connected to it.
  • the invention instead concerns the development of a simplified solution that allows for the creation of an alternative method for sealing the aperture between a sanitary insert part and the water outlet of a sanitary fitting to which it is connected.
  • the invention proposes that at least one discharge opening—approaching the jet aeration device from the outside—should be formed between the seal element and the securing means. Water escaping through the seal can thus be easily absorbed and returned to the main flow path, without requiring the attention of the user. This means that water leakage through the securing means on the outlet side can be significantly reduced or even avoided altogether.
  • the seal element can achieve a complete seal using this method. However, its effect is already achieved if the seal element results in only a partial seal, as this generates a pressure difference across the seal element.
  • This pressure difference can, for example, be set so that a substantial part of the water escaping through the seal element—or even all of the water escaping—is channelled into the discharge opening.
  • the securing means can be installed as a releasable connection with a counter securing means.
  • the securing means can be adapted for a screw connection, plug connection, swivel connection and/or a snap connection, as well as a combination of one or more of these connection types, either with connections of the same type or connections of other types.
  • the jet aeration device acts as a flow barrier in the main flow path.
  • the flow barrier can subsequently cause a drop in pressure relative to the inlet side, enabling any leakage to be returned to the main flow path.
  • the securing means When configuring the invention, there is the option of attaching the securing means to a base structure. This results in the possibility of achieving a single stop function for the water outlet. This may be beneficial if, for example, the securing means is a thread connection or twist-and-lock joint.
  • the invention can be configured so that the discharge opening is attached to a base structure.
  • the discharge opening (one minimum) could be formed, for example, using injection moulding technology.
  • a seal element with a radial seal design. Due to radial material displacement, a radial seal has the advantage of generating contact pressure and therefore only a comparatively low level of force would be required when inserting the insert part into the water outlet.
  • seal element uses a design that features a radial and an axial seal.
  • the seal element can therefore be used for a number of water outlets with different designs in which it seals either radially or axially or both radially and axially.
  • the base structure can be designed as several composite parts.
  • the advantage here is that different materials can be used for each part.
  • Another advantage is that more complex shapes can be achieved for use in the base structure.
  • the base structure When configuring the invention, there is the option of producing the base structure using plastic. This allows for the base structure to be produced at low cost, for example as a part created through injection-moulding technology. As a material, plastic may also work well as it can serve to avoid or reduce lime scale deposits.
  • the collection chamber prefferably be designed as a ring-shaped circumferential groove. This allows for unwanted water leakage along the entire outer circumference of the insert to be reduced or avoided altogether.
  • the securing means When configuring the invention, there is the option of designing the securing means as a thread connection which would fit into a counter thread at the water outlet of a sanitary fitting.
  • a thread connection provides a particularly straightforward means of attaching the insert part to the water outlet.
  • a thread connection may also act as a flow barrier where it meets the counter thread. As such it is particularly important to ensure that leachate is collected through the discharge opening rather than through the thread connection.
  • the features of this subsidiary claim relate to the formation of the outlet assembly for the invention.
  • the insert part should be designed according to this invention and/or in line with the requirements for such an insert part.
  • sealing the annular gap between the insert and the water outlet of the fitting should be straightforward and a sufficiently tight seal should result without excessive demands being made of the seal element.
  • the sanitary insert part is designed in line with this invention and in particular as described above, and/or in line with the requirements for such an insert part. This will ensure that a synergy of the various advantages described above can be achieved.
  • the seal element When configuring the invention, it is intended that the seal element will result in pressure reduction in the leachate path. This in turn relieves the burden on the securing means.
  • flow resistance generated by the seal element should be greater than the flow resistance in the section of the main flow path running parallel to the seal element in the insert part. This serves to avoid any impairment of the function of the functional unit in the main flow path, e.g. its function as a jet aeration device.
  • a volume flow of a leakage flow is not very durable compared to the main flow.
  • the invention concerns a sanitary insert part with an inlet side and an outlet side, wherein a securing means is formed between the inlet side and the outlet side, wherein the securing means is designed to be detachably secured to a counter securing means on a water outlet of a sanitary fitting, wherein a seal element is formed between the securing means and the inlet side, creating an at least partial seal; and with a jet aeration device which has an aeration access point that is open towards the outlet side; and with a discharge opening formed between the seal element and the securing means which connects the outside of the sanitary insert to an aeration chamber on the aeration device.
  • FIG. 1 A partial, cross-section, perspective view of a design of a sanitary insert part in line with the invention, which is inserted into a water outlet of a sanitary fitting, with the seal element providing a radial seal for the aperture between the insert part and the water outlet;
  • FIG. 2 A detailed view of the first circled section of the sanitary insert part in FIG. 1 , which shows an enlarged version of the discharge opening between the seal element and the securing means;
  • FIG. 3 An enlarged, detailed view of the second circled section in FIG. 1 , which shows the collection chamber;
  • FIG. 4 A vertical cross-section view of another design example for the sanitary insert part, which is inserted into a water outlet of a sanitary fitting, with the seal element providing an axial seal for the aperture between the insert part and the water outlet;
  • FIG. 5 An enlarged, detailed view of the circled section in FIG. 4 showing the axial seal between the insert and the water outlet.
  • FIGS. 1 to 5 show a sanitary insert part, the whole of which is marked as key term 1 .
  • the sanitary insert part 1 is designed to be attached to and detached from a water outlet 5 of a sanitary fitting, enabling straightforward replacement.
  • the sanitary insert part 1 has an inlet side 2 facing upwards on FIGS. 1 and 4 and an outlet side 3 facing downwards.
  • a securing means 4 provided between the inlet side 2 and the outlet side 3 , which is designed to enable attachment of the sanitary insert part 1 to a counter securing means 6 of a sanitary fitting during assembly.
  • the base structure 12 should be at last partly cylindrical in design.
  • the securing means 4 is located on an outer surface of the base structure 12
  • the counter securing means 6 is located on an inner surface of a water outlet 5 of the sanitary fitting.
  • the securing means 4 can be designed as a thread connection and, in particular, as an external thread connection.
  • the counter securing means 6 can also be designed as a corresponding counter thread connection, i.e. an internal thread connection.
  • the sanitary insert part 1 also has a seal element 7 , which, as shown in FIGS. 1 to 3 , allows for a radial seal to form in the aperture 19 between the sanitary insert part 1 (and in particular, the outer side of the sanitary insert part) and the water outlet 5 of the sanitary fitting.
  • the end stop 12 to which the seal element 7 is attached during assembly, is installed at an angle to the direction of flow of the water and/or the direction of insertion of the sanitary insert part 1 .
  • the seal does not have to provide a complete seal of the aperture 19 , as any water that flows through the aperture 19 in spite of the seal will be returned to the main flow path through the downstream side of the seal element 7 .
  • FIGS. 4 and 5 illustrate an additional use of the sanitary insert part 1 with a water outlet 5 using a different design. It features a water outlet 5 with an end stop 21 that is different from that shown in FIGS. 1 to 3 .
  • An axial seal is formed using a seal element 7 , which provides an at least partial seal preventing water from passing through the aperture 19 .
  • the end stop 21 to which the seal element 7 is attached during assembly, is installed perpendicularly, i.e. vertically, to the direction of insertion of the sanitary insert part 1 .
  • the sanitary insert part 1 can be inserted into a number of water outlets with different designs without the need for additional structural changes. More specifically, it functions equally well in use with water outlets whose stop surfaces—against which the seal element 7 is placed—are aligned transversely and/or perpendicularly to the direction of insertion of the sanitary insert part 1 and/or the direction of flow of the water.
  • the seal element 7 is therefore able to accommodate two types of stop surface 22 arranged apart from one another, which are then adapted to form two different types of seal with an end stop 21 for the sanitary fitting.
  • the seal element 7 is annular and attached as a component to the multi-part base structure 12 . It is, however, conceivable that the seal element 7 could be created as part of the base structure 12 itself, for example as an element of a single-unit base structure 12 or as an element of one part of a multi-part base structure 12 , i.e. the upper part.
  • the sanitary insert part 1 has a jet aeration device 8 attached to the base structure 12 , which itself features an aeration access point 9 that opens towards the outlet side 3 .
  • the jet aeration device 8 contains a flow barrier 11 , which can serve a range of functions, for example, as an impact surface with nozzle openings.
  • a flow barrier 11 can serve a range of functions, for example, as an impact surface with nozzle openings.
  • the sanitary insert part 1 In order to return water that escapes through the aperture 19 to the main flow path—i.e. due to an incomplete seal—the sanitary insert part 1 is fitted with at least one discharge opening 10 between the seal element 7 and the securing means 4 , leading ultimately to the jet aeration device 8 .
  • the discharge opening 10 which is formed as part of the base structure 12 , is connected to an opening on the sanitary insert 1 , allowing water that escapes through the aperture 19 to be redirected through the discharge opening 10 and preventing this water from impairing the jet pattern.
  • the discharge opening 10 In the direction of flow of water, the discharge opening 10 is located downstream of the flow barrier 11 , but at a distance behind the securing means 4 .
  • a number of similar discharge openings 10 have been created, which together cover a large portion of the outer circumference.
  • the discharge openings 10 are arranged above the collection pocket 26 , which is created on the base structure in the form of a circular groove. As such, this collection pocket 26 carries water that escapes past the seal element 7 and transports it to the discharge openings 10 .
  • the sanitary insert part 1 has a multi-part base structure 12 , comprising three respective parts.
  • the base body 12 shown above, for example, is comprised of the seal element 7 , an upper part 13 and a lower part 14 .
  • the flow barrier 11 can be designed as part of the upper part 13 .
  • the aeration chamber 25 can be formed by the lower part 14 .
  • the upper part 13 and or the lower part 14 and/or the seal element 8 can be locked via a mechanical connection, as illustrated here with a snap-fit connection.
  • the parts that fit together have snap connectors 23 and/or corresponding counter snap connectors 24 .
  • the seal element 7 can also be designed together with the upper part 13 as a single unit. Here, it is advisable if the upper part 13 has a greater deformability (preferably elastic) than the lower part 14 .
  • FIGS. 1 and 3 illustrate a collection chamber 15 that has been adapted to collect water passing through the leachate path between the securing means 4 and the counter securing means 6 to prevent unwanted leaking.
  • the collection chamber 15 is located before the aeration access point 9 in the direction of the flow being drawn in.
  • the collection chamber 15 has a lip seal 17 which is used to seal it to the outside of the lower part of the water outlet 5 .
  • the collection chamber 15 also has an overflow opening 16 through which the excess water that can no longer be held by the collection chamber 15 is released. As part of the flow of water through the sanitary insert part 1 , this water is carried into the aeration chamber of the jet aeration device 8 through the aeration access 9 alongside the air that is also being drawn in. This works to prevent the loss of leaking water via the leachate path 20 , which would otherwise have an adverse effect on the overall jet pattern.
  • the flow resistance between the discharge opening 10 and the outlet side 3 must also be lower than the flow resistance in the leachate path 20 , which comprises the area between the securing means 4 and the counter securing means 6 .
  • the seal element 7 also causes a reduction in pressure along the leachate path 20 , as the flow resistance generated by the seal element 7 is greater than a flow resistance across the section of the main flow path that runs parallel to the seal element 7 in the sanitary insert part 1 .
  • the outlet side 3 of the sanitary insert part 1 also features a grooved tool attachment 18 .
  • the sanitary insert part 1 can be inserted, i.e. screwed, into the water outlet 5 or detached, i.e. unscrewed, from the water outlet 5 by attaching a tool the tool attachment 18 and using an opening motion, preferably a rotary movement.
