[0036] exist figure 1 , 2 The three embodiments of the jet regulator indicated in 1 are shown in 4, 5, 6, 6, 6, 8, and 9. The jet regulator 1 is provided for generating a gas jet.
[0037] The jet regulator 1 has a housing 2, via the housing, and the jet regulator 1 can be connected to the jet regulator receptacle of the sanitary outlet fitting. For this purpose, a coupling portion can be configured on the outer side of the housing 2, which is capable of joining the corresponding fit coupling portion of the sanitary outlet fitting.
[0038] A jet acceleration device 3 is disposed inside the housing 2. The jet acceleration device 3 is provided for decomposing the jet flowing into the jet acceleration device 3 into a plurality of liquid shares separated from each other.
[0039]The screen 23 can be provided on the inverted side upstream of the jet acceleration device 3.
[0040] The flow direction 4 along the (liquid flow versatile regulator 1) is provided with a jet air supply device 5 downstream of the jet acceleration device 3. The jet air supply device 5 is provided for mixing the separated liquid shares with air. To this end, the jet air supply device 5 has a space 6 that produces a liquid-air mixture during the spatial in the spatial. The jet air supply device 5 has at least one air interface 7 that can be suck the air from the outside to the space 6 or during use.
[0041] exist Figure 1 to 9 In the illustrated embodiment, the space 6 of the jet air supply device 5 corresponds to a plurality of air port 7, which is formed in the side wall 17 of the space 6 in the same spacing as each other.
[0042] A well plate 8 is disposed or constituting the space 6, which divides the space 6 into an air entry portion 9 and the mixed portion 10. The air entry portion 9 and the mixed portion 10 are in communication with each other via the plate opening 11 of the orifice plate 8. Therefore, the liquid and air can enter the mixed portion 10 via the plate opening 11. The splash water from the mixing portion 10 can be blocked by the orifice plate 8, so that the mixed water does not reach the outside. The well plate 8 can be made, for example, plastics, metals, ceramics, and / or other materials.
[0043] The orifice plate 8 is oriented across or perpendicular to the longitudinal axis 12 of the housing 2 and / or perpendicular to the flow direction 4 in which the housing 2 is inside or perpendicular to or perpendicular to the flow direction 4 of the liquid.
[0044] The well plate 8 can have a planar or almost flat plate body 29. Alternatively or supplemented, the orifice plate 8 can have a sleeve shape 28. Preferably, the sleeve shape can extends into the air entry portion 9 and / or protrude from the upper side of the plate body 29. Therefore, it is also possible to better prevent splash water from returning from the mixing portion 10 through the orifice plate 8 to the air entry portion 9.
[0045] The orifice plate 8 can be integrally formed on the housing 2 or constitute a separate member. The integrated design has the advantage that the jet regulator 1 has less components. The orifice plate 8 designed to separate components has the advantage that the manufacturing of the jet regulator 1 is simplified.
[0046] The at least one airfringe 7 of the jet air supply device 5 constitutes a side wall 17 of the section of the space 6 forming the air entry portion 9. The air port 7 thus wears the housing 2, so that the air entry portion 9 is at least partially open at lateral direction.
[0047] In contrast, the mixture of air and liquid is carried out in the mixed portion 10. In particular, the mixing of air and liquid is only carried out in the mixed portion 10, so that air and liquid are separated and / or two differentially through the plate opening 11 into the mixed portion 10. The orifice plate 8 is disposed downstream of the at least one airfill 7 along this flow direction 4. This has the advantage that impact water (splash water) is not formed over the orifice plate 8. Therefore, the leakage risk caused by the discharge through the liquid via the air passage 7 is achieved.
[0048] The jet acceleration device 3 has at least one nozzle 13. By the at least one nozzle 13 can be jet acceleration during use in the jet regulator 1. Thereby, a negative pressure is formed in the space 6 of the jet air supply device 5, and air is suiled from the outside to the space 6 via the air pressure, and the space can be used to generate a gas. Jet. Further, it can be provided that a jet is appended from a plurality of separate liquid shares by adding a jet acceleration device 3, which improves the next jet.
[0049] The at least one nozzle 13 can further decompose the jet into a plurality of separate liquid shares. This has the advantage that the liquid and air can be mixed by decomposition into a plurality of separated liquid shares. For example, the nozzle 13 can be configured as an atomizer nozzle to form a fog and / or an aerosol.
[0050] The nozzle 13 may, for example, be provided to generate a cone jet 24 composed of a plurality of liquid shares. Preferably, the cone jet 24 can be configured such that the diameter of the tapered jet 24 is smaller than the diameter of the plate opening 11 at the height of the plate opening 11.
[0051] The height of the cone jet 24 can be greater than the height of the air entry portion 9 of the space 6. Therefore, the cone jet 24 can extend from the air entry portion 9 through the orifice plate 8 until the mixed portion 10. This has the advantage that the splash water can be prevented from being produced upstream of the orifice plate 8 along the flow direction 4 and in addition to the inner portion of the mixed portion 10.
[0052] The nozzle 13 can be constructed, for example, by embedding the insert 22 into the through hole 15 of the jet acceleration device 3. By changing the insert 22 and / or the diameter of the through hole 15, the nozzle characteristics can be influenced.
[0053] The orifice plate 8 can be disposed inside the space 6 such that the orifice plate is continuously surrounded by the inner wall 14 of the space 6. Therefore, splash water can be mainly blocked in the edge region. The sprayed water returns splashing through the plate opening 11 is sent back to the mixed portion 10 through the air flow and / or the liquid shares.
[0054] The orifice plate 8 may have a plate body 29, and a recess 25 is formed on the plate body. In the mounting position, the side wall 17 of the surrounding air entry portion 9 can be embedded in the recess 25 and the orifice plate 8 can be held in its position. Therefore, the jet regulator 1 can be installed particularly simply.
[0055] The housing 2 is preferably configured in one piece. All of the members of the jet regulator 1 then can be embedded in the housing 2 and thereby remain in its predetermined position. Therefore, the jet regulator 1 can also be installed particularly simply.
[0056] The housing 2 can, for example, be a sleeve shape and / or at least partially cylindered.
[0057] The jet acceleration apparatus 3 has at least one through hole 15, and the through hole can, for example, be composed of the aforementioned nozzle 13. As shown, the jet acceleration apparatus 3 may have only one single nozzle as a through hole 15.
[0058] The mixed portion 10 can have a volume of 9 larger than the air entering portion, such as Figure 1 to 4 And 8 shown. Since the air entry portion 9 does not set a mix of liquid and air, the structural space required for this can be reduced.
[0059] Alternatively or supplemented, the air port 7 can be designed to be as large as possible such that the area of the closed side wall 17 of the air enters portion 9 and the air access portion 9, especially in the air entering portion 9 The circumferential surface is compared to the area of the air outlet 7 and has a small area share. Therefore, air can be taken particularly well in the case of small space requirements as possible.
[0060] In order for regardless of the relatively small volume of the mixing portion 10, the liquid and the air can be particularly mixed, the mixing portion 10 can have a hit body 26, which is disposed inside the flow path as a flow barrier 18. The impact body 26 can be at least partially extending into the air entry portion 9. Preferably, the highest point of the impact body 26 is at the height of the upper edge of the sleeve section 28 of the hole plate 8 in the mounting position.
[0061] The discharge angle 16 of the through hole 15 can be adjusted such that the liquid flows into the mixed portion 10 from the through hole 15 from the through hole 15 during use during using the jet regulator 1. Therefore, this is not hindered, and the liquid is not impact on the surface of the plate along the flow direction 4, but the plate opening 11 of the direct flow through the hole plate 8. By adjusting the discharge angle 16 of the at least one through hole 15, the liquid is Figure 1 to 4 In the embodiments of the 8 and 9, the sidewall 17 of the mixing portion 10 is directed to the mixing portion 10 during the embodiment of the 8 and 9. The vortex is generated inside the mixed portion 10 by the impact of the liquid and the side wall 17, and the liquid share can be better compared to air by eddy current.
[0062] exist Figure 5 to Figure 7 In the embodiment, the discharge angle 16 of the through hole 15 is adjusted such that the jets accelerated by the jet acceleration device 3, in particular directly and / or unspecified, in particular directly and / or unspecified.
[0063] In order to be able to further mix, the flow barrier 18 can be designed within the mixing portion 10, such as on the side wall 17 of the mixing portion 10. The side wall 17 forms a hit surface, wherein the flow barrier 18 is directed laterally to the impact surface orientation. The flow obstacle 18 may, for example, have a shape of the projection 19. according to Figure 1 to 4 The projections 19 of the embodiments of 8 and 9 extend radially inwardly and thus the liquid share of the flow into the mixing portion 10 (which flows along the inner wall along the inner wall) inwardly. Therefore, a particularly preferred mixing of liquid shares and air can be achieved.
[0064] Alternatively or supplemented, the impact body 26, acceleration, and / or decomposed liquid shares impact on the impact body in the mixed portion 10. The impact body 26 can be designed, for example, tapered. The impact body 26 has a hit surface, which constitutes or provided with a plurality of impact elements 27. The impact element 27 can, for example, insertically and protrude from the impact surface and / or transverse to the impact surface of the impact body 26. Preferably, the impact element 27 can be oriented parallel to the flow direction 4.
[0065] according to Figure 8 with 9 The illustrated jet regulator 1 embodiment may be at least partially funnel design. This has the advantage that when the discharge angle 16 of the through hole 5 is oriented such that the liquid from the side wall 17 of the mixing portion 10 collided, the splash water from the mixing portion 10 is also better being blocked by the orifice plate 8.
[0066] In order to generate a particularly attractive jet outflow image, the bottom region 20 of the mixing portion 10 can be constructed at least partially by the outflow structure 21. The outflow structure 21 can have a plurality of discharge ports, by the discharge port, a plurality of single radiations on the outflow side of the jet regulator 1.
[0067] The present invention is therefore, in particular, a reflow regulator 1, for embedding into a bath, wherein the jet regulator 1 has a housing 2, a jet acceleration device 3, and a flow direction 4 in a jet acceleration device 3. The downstream jet air supply device 5, wherein the jet angle device 5 has a space 6 having at least one airfill port 7, and the air can draw air from the outside to the space 6, wherein The space 6 is provided with a hole plate 8, which divides the space 6 into an air entry portion 9 and a mixing portion 10, wherein the air is sucking air from the outside in the air entry portion 9 and liquid in the mixed portion 10. Mixed with air.
