Description

TECHNICAL FIELD

[0001] The invention relates to a jet regulator, for example for use on sanitary fittings. Such a jet regulator can constitute two mutually separate, mutually nested channels, wherein a splitter unit is assigned to the outer of the two channels, the water guide of the inner of the two channels passing through the splitter unit. BACKGROUND

[0002] Such a jet regulator is already known in practice. It can be used, for example, on sanitary fittings which themselves have two different water guides, for example one water guide for cold water and a second water guide for warm, hot or boiling water. SUMMARY

[0003] It is the task of the invention to provide a jet regulator of the type mentioned at the outset, which is characterized by a simple construction and associated simple assembly and operation.

[0004] To solve this task, a jet regulator of the type mentioned at the outset is first proposed, which has the mechanisms and features for such a jet regulator. In particular to solve the task in a jet regulator of the type mentioned at the outset, it is therefore proposed that the water guide of the inner channel is latched in the splitter unit of the outer channel and thereby secured in both axial directions.

[0005] In this way, the splitter unit of the outer channel acquires a dual function:

[0006] On the one hand, the splitter unit serves to split the water flowing through the outer channel and, if necessary, to mix it with air, on the other hand, the splitter unit functions as a fastening mechanism which secures the water guide of the inner channel in both axial directions relative to the remaining elements of the jet regulator.

[0007] The water guide of the inner channel can be a water guide sleeve. It is also possible that the water guide has a peripherally situated latching groove in which the splitter unit is arranged in the case of the water guide being in the latched position of use. The latching groove can define the relative position of the water guide relative to the splitter unit and furthermore cause a structurally simple and at the same time reliable axial securing of the water guide on the splitter unit in both axial directions.

[0008] The catch groove can be defined axially by the two shoulders of the water guide. In the position of use, the resolver unit can be arranged between the two shoulders of the water guide and in the catch groove. In order to simplify the assembly of the fluidic regulator, it can be expedient that one of the two shoulders of the water guide, in particular the shoulder of the outflow side of the water guide, has a smaller radial extension than the other shoulder of the water guide, through which the catch groove of the water guide can be defined. The shoulder of the water guide having the smaller radial extension can be equipped with a preferably outflow-side assisting inclination, for example in the form of an assisting taper, through which the resolver unit can be introduced into the catch groove of the water guide.

[0009] In order to solve the task, a fluidic regulator of the type mentioned at the outset is also proposed, which has the features and the means for such a fluidic regulator. In order to solve the task, a fluidic regulator is therefore also proposed, in particular, which comprises a resolver unit and an additional sieve, which is fastened on the resolver unit with an anchoring element, which engages the resolver unit from the back on the outflow side. By means of the anchoring element, the additional sieve can be fastened on the resolver unit. This can simplify the construction of the fluidic regulator and its assembly and make it more robust.

[0010] In one embodiment of the fluidic regulator, it is provided that the features are respectively for a fluidic regulator.

[0011] In one embodiment of the fluidic regulator, it is provided that the anchoring element is one, for example the previously mentioned water guide, of the fluidic regulator. The water guide can be the water guide for the previously mentioned internal passage. In this way, the anchoring element not only assumes the function as a means for fastening the additional sieve on the resolver unit, but also assumes the function as a water guide. Here, the anchoring element can have a shoulder, which engages the resolver unit from the back on the outflow side. The resolver unit can rest on the shoulder of the anchoring element on the outflow side in the position of use and provide a connection between the anchoring element and the resolver unit, through which, finally, the additional sieve is also fixed on the resolver unit.

[0012] In one embodiment of the fluidic regulator, it is provided that the anchoring element penetrates the resolver unit and / or the additional sieve. For this purpose, the resolver unit and / or the additional sieve can have a respectively preferably central opening, through which the anchoring element, in particular the water guide, passes in the position of use in order to fasten the additional sieve on the resolver unit.

[0013] In one embodiment of the fluidics regulator it is provided that the resolver unit has a shoulder on the inflow side. The additional sieve can rest on the shoulder on the inflow side. By means of the shoulder of the resolver unit the additional sieve can thus be fixed in its position on the outflow side with respect to the resolver unit and the anchoring element, in particular the inner channel, for example the already mentioned inner channel, of the water guide.

[0014] In one embodiment of the fluidics regulator it is provided that the anchoring element has a stop, in particular on the inflow side. The additional sieve can rest on the stop and be axially stopped and fixed in position on the inflow side. In this embodiment of the fluidics regulator the additional sieve can thus be arranged between the resolver unit and the anchoring element and be fixed in its position by them in both axial directions. The additional sieve is thus fixed between the resolver unit and the anchoring element which is fastened on the resolver unit.

[0015] In one embodiment of the fluidics regulator it is provided that the anchoring element is detachably connected with the additional sieve. Thus, the anchoring element can be manufactured separately from the additional sieve.

[0016] In one embodiment of the fluidics regulator it is provided that the resolver unit has a resolver plate or is configured as a resolver plate.

[0017] In one embodiment of the fluidics regulator it is provided that the water guide ends above the discharge structure of the fluidics regulator. In another embodiment of the fluidics regulator it is provided that the water guide leads through the discharge structure of the fluidics regulator. The water guide can project, if necessary, from the discharge structure, in particular from a discharge structure into which the outer channel of the two channels opens.

[0018] The fluidics regulator can have at least one additional sieve and / or at least one sieve insert in the region of the water guide. The at least one additional sieve and / or at least one sieve insert can have a gap through which the water guide of the inner channel leads. Here, the gap can be spaced apart from the water guide. This is advantageous in order to achieve that already existing additional sieves and / or sieve inserts can be used with the water guide without structural changes. The spacing enables a sufficient residual wall thickness in the component which facilitates economical manufacture, for example in plastic injection molding.

[0019] In the water guide a sieve element can be arranged and / or configured. The sieve element can be integrally formed on the water guide.

[0020] It can be provided that the resolver unit and the additional sieve are detachably or non-detachably connected with one another. The respective connection can be realized, for example, by a corresponding snap connection. By means of a non-detachable snap connection a washout of the additional sieve can be prevented.

[0021] The anchoring element can be detachably or non-detachably connected with the resolver unit. The respective connection can be realized, for example, by a corresponding snap connection.

[0022] A detachable snap connection can be characterized, for example, in that it becomes more flexible under load, while a non-detachable snap connection is more strongly caught under load. A non-detachable snap connection can be realized, for example, by an angle setting formed on the bottom of the undercut, which angle is equal to or less than 90°.

[0023] A detachable snap connection can be produced more simply when the ejection direction coincides with the insertion direction of the snap connection. Since the ejection is then typically carried out as a forced ejection over the undercut, this is difficult when the snap connection should be non-detachable, i.e. self-fixing. In this case a multi-part or movable core must then be used, which is very expensive.

[0024] The resolver unit can be characterized, for example, functionally: the resolver unit can force the flow onto a defined path in order to decouple subsequent flow conditions from given conditions upstream.

[0025] The diffuser can be characterized, for example, functionally: the diffuser can force the flow towards a radial flow with subsequent vortex.

[0026] The sieve element can be characterized, for example, functionally: the sieve element can have an effect of the same orientation on a water flow. BRIEF DESCRIPTION OF DRAWINGS

[0037] The figure shows a flow regulator, designated as a whole with 1, which constitutes two mutually separate, mutually nested channels 2 and 3. A resolver unit 4 is assigned to the outer channel 2 of the two channels 2 and 3. The water guide 5 of the inner channel 3 of the two channels 2 and 3 passes through the resolver unit 4.

[0038] In particular Figure 6 and 7 the sectional view shows that the water guide 5 of the inner channel 3 is latched in the resolver unit 4 and thereby fixed in both axial directions.

[0039] The water guide 5 of the flow regulator 1 is configured as a water guide sleeve. It has a peripherally situated latching groove 6 in which the resolver unit 4 is disposed in the water guide 5 in the latched, used position.

[0040] The latching groove 6 is axially delimited by two shoulders 7 and 8 of the water guide 5. The outflow-side shoulder 7 here has a smaller radial extent than the other inflow-side shoulder 8 of the water guide 5. This makes it easy for the resolver unit 4 to be introduced into the latching groove 6 by means of the outflow-side shoulder 7 of the water guide 5 and thereby for the water guide 5 to be fixed on the resolver unit 4 of the flow regulator 1.

[0041] In addition, the outflow-side shoulder 7 with the smaller radial extent is assigned an outflow-side assist bevel 9. The assist bevel 9 is configured as an assist cone in the shown embodiment. By means of the assist bevel 9, the resolver unit 4 can be introduced relatively simply into the latching groove 6 of the water guide 5 when the flow regulator 1 is assembled.

[0042] The flow regulator 1 furthermore has an additional sieve 10 for the outer channel 2, which is fastened on the resolver unit 4 and the water guide 5.

[0043] The additional sieve 10 for the outer channel is fastened on the decomposer unit 4 with the anchoring element 11. In the fluidic regulator 1 shown in the figures, the water guide 5 for the inner channel 3 also serves at the same time as anchoring element 11 for fastening the additional sieve 10 on the decomposer unit 4. The anchoring element 11 here engages the decomposer unit 4 from the back on the outflow side. This is particularly well visible in the sectional view of the fluidic regulator 1 according to Figure 6 and 7 .

[0044] In the embodiment of the fluidic regulator 1 shown in the figures, the previously mentioned shoulder 7 of the water guide 5 on the outflow side, which limits the latching groove 6 of the water guide 5 on the outflow side, engages the decomposer unit 4 from the back.

[0045] The decomposer unit 4 has a convex shoulder 12 on the inflow side, by means of which the additional sieve 10 is fixed axially on the outflow side. The additional sieve 10 is placed on the decomposer unit 4 on the convex shoulder 12 of the decomposer unit 4 on the inflow side. The convex shoulder 12 of the decomposer unit 4 on the inflow side here engages the additional sieve 10 from the back on the outflow side.

[0046] The additional sieve 10 is axially stopped on the inflow side by the stop 13 of the water guide 5 on the inflow side. The additional sieve 10 is thus axially stopped in its position relative to the decomposer unit 4 and the water guide 5 on the one hand by the convex shoulder 12 of the decomposer unit 4 on the inflow side and on the other hand by the stop 13 of the water guide 5 on the inflow side.

[0047] Here, the decomposer unit 4 and the additional sieve 10 are connected to one another by a detachable snap connection. The anchoring element 11 and the additional sieve 10 are likewise connected to one another by an undetachable snap connection. By means of these undetachable snap connections, a washing away of the additional sieve 10 is prevented.

[0048] The anchoring element 11 is undetachably connected to the decomposer unit 4. This also prevents the additional sieve 10 from being washed away together with the anchoring element 11.

[0049] The decomposer unit 4 of the fluidic regulator 1 has a decomposer plate 14. In an embodiment of the fluidic regulator not shown in the figures, the decomposer unit 4 can alternatively have a diffuser.

[0050] In the fluidic regulator shown in the figures, the water guide 5 is designed in such a way that the water guide 5 guides the discharge structure 22 for the outer channel 2 through the fluidic regulator 1.

[0051] Figure 7The fluidics regulator 1 is shown in the position of use on a fitting 15. The fitting 15 has a first input line 16 which opens into the passage 2 outside the fluidics regulator 1. A second input line 17 of the fitting 15 is connected to the passage 3 inside the fluidics regulator 1.

[0052] The fitting 15 has an external thread 18 with which a threaded sleeve 19 of the fluidics regulator 1 is used to fasten the fluidics regulator 1 on the fitting 15 by screwing.

[0053] The sieve element 23 is formed in the water guide 5.

[0054] The sieve element 23 is spaced apart from the discharge end of the water guide 5, so that the water jet can recombine and then does not have a gap, for example, on the web. Furthermore in this way the mold now has to move half the stroke twice when demolding relative to the full stroke. The sieve element 23 is shaped here onto the water guide 5 and forms with it a unit of material-uniform whole.

[0055] On the outflow side of the resolver unit 4, the fluidics regulator 1 has a further sieve insert 20 in the region of the water guide 5, which radially surrounds the water guide 5. The water guide 5 here leads through an opening 21 of the sieve insert 20, wherein the edge of the opening 21 is arranged spaced apart from the water guide 5.

[0056] The resolver unit 4 and the additional sieve 10 also have an opening 21 through which the water guide 5 passes.

[0057] The invention is directed to an improvement in the technical field of fluidics regulators. As an improvement, primarily a fluidics regulator 1 is proposed which comprises two mutually separate, mutually nested passages 2 and 3, wherein the water guide 5 of the inner passage 3 is latched in the resolver unit 4 assigned to the outer passage 2 of the two passages 2 and 3 and thereby fixed in both axial directions.
