Definitions

  • the invention relates to a shower head for a sanitary shower.
  • sanitary showers be they hand showers, overhead showers or side showers with which a massage effect is to be achieved.
  • mechanically moving elements are used, which can lead to an interruption of the individual water jets.
  • oscillators that change the direction of the exiting water jets.
  • Another way to make a type of massage can be aerated water jets.
  • a partially rotating water flow is generated in a cylindrical chamber within the shower head.
  • a part of the water flowing into the shower is directed axially into the chamber, while the remaining part of the water is introduced at several points obliquely to the axis of the cylindrical chamber.
  • One end of the chamber is provided with the jet disk.
  • the water is introduced tangentially in a shower housing at the point with the smallest diameter.
  • the showerhead then widens in a funnel shape, and at the end with the largest diameter, the jet outlet openings are arranged.
  • a fitting for connection to conventional pressurized water lines which has a pear-shaped housing into which the water flows axially, a turbine is rotated and then passed through radially extending channels to the outside against the expanding wall of a chamber ( DE 3828111 A1 ).
  • a shower head with a cylindrical chamber and a tangential water inlet into the chamber. This is intended to set a discharge nozzle in vibration ( WO 95/23029 ).
  • the invention is based on the object to provide a shower head for a sanitary shower that can produce without moving parts effervescent spray with a massage effect with special effects.
  • the invention proposes a shower head with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the chamber formed in the showerhead housing which could also be called a vortex chamber, has in a cross-section parallel to the jet disk a rounded circumference in order to support the vortex generated by the tangentially entering water. It has surprisingly been found that the circumference or the cross section through the vortex chamber does not have to be circular. Also, an oval shape, which leads to an elongated shape of the jet exit disc can be provided in this way with a massage effect. As a result, there are greater possibilities for the shaping of a shower.
  • the water guide for the water entering the chamber also opens tangentially in the axial direction in the inlet region of the chamber.
  • the axial direction is to be understood as the direction which is perpendicular to the jet exit disc.
  • the tapering region adjoining the inlet region of the chamber preferably begins in a development such that its wall begins almost parallel to a cross-sectional plane. In other words, at the beginning of the tapering area, a large reduction in the cross-section of the chamber takes place.
  • the wall of this region then approaches along a curved transition a direction which runs perpendicular to the jet disk, so that therefore the end of the tapering region has a wall which runs tangentially to the axial direction.
  • transition between the beginning and the end of the tapering region thus runs along a more or less curved contour, so that the vortex generated in the chamber undergoes no disturbance along this harmonic transition.
  • the rejuvenation range can be configured in a development of the invention so that the diameter of the chamber is significantly reduced during its course, for example in the ratio of about 2: 1 to about 6: 1.
  • the axial extent of the tapering region that is to say the dimensions perpendicular to the cross section running parallel to the jet disk, can be significantly smaller than the maximum diameter of the chamber.
  • the axial extent may be, for example, in a range from 1: 2 to about 1: 5 in relation to the maximum diameter of the vortex chamber.
  • the shower head which the invention proposes, should not necessarily differ in its external design from conventional forms, can be provided according to the invention in development that the water inlet is arranged radially in the housing. If it is the shower head is a hand shower, so can still be arranged the handle of the hand shower radially to the shower head.
  • the water inlet into the housing can take place in the axial direction, that is to say perpendicularly to the jet disk.
  • this inlet is not located in the middle of the housing of the shower head, but laterally offset.
  • the water guide is formed from the water inlet to the chamber as a channel outside at least the chamber as far as the circumference of the chamber along, that it reaches at least approximately tangentially into the chamber, for example over an arc length of 20 °, preferably over an arc length of at least about 45 °.
  • this channel then opens as an outlet.
  • the outlet opening preferably also extends along the circumference, again along an arc length sufficient to ensure its entry into the chamber in a vortex-generating direction. These may be, for example, at least about 15 °.
  • outlet opening of the channel lies in a plane which runs parallel to the jet disk.
  • the outlet opening of the channel is opposite the wall of the beginning of the tapering area that is approximately located in a radial plane.
  • the incoming water is therefore already passed directly into the rejuvenation area.
  • the channel of the water guide already has a gradually decreasing cross section. This achieves a uniform and defined input beam into the vortex chamber.
  • the tapering region has a decreasing cross-section, it ends at a point of the smallest cross-section, ie a bottleneck.
  • a jet outlet chamber which is bounded by the jet disk at this point. It is thus between the end of the tapering area, so the bottleneck, and the jet disc a certain distance available. This distance forms the thickness of the jet outlet chamber.
  • the diameter of the jet outlet chamber can be identical to the diameter of the constriction, depending on the requirements of the individual case.
  • the diameter of the jet outlet chamber is greater than the minimum diameter of the tapering region, in particular significantly larger.
  • the diameter of the Jet outlet chamber is about the same size or even slightly larger than the maximum diameter of the vortex chamber in its inlet area.
  • the jet outlet chamber is closed on its side facing away from the jet disc around a ring around the end of the tapering region.
  • This floor can be particularly flat.
  • the jet exit chamber formed between the jet exit disc and the bottom is preferably designed as a flat chamber whose thickness is significantly smaller than the diameter of the exit opening of the tapering region.
  • the water inlet into the vortex chamber occurs at the point where the vortex chamber has its largest diameter. According to the invention, provision can now be made for the chamber formed in the shower head to continue on its side of the inlet area facing away from the jet disk, as far as a rear wall of the shower head housing.
  • the jet disk has multiple areas that can be supplied separately by means of a switching device with water.
  • the areas may have different sized jet outlet openings to produce in this way differently acting massage jets. For example, one can be harder in the middle Generating massage jets, while at the edge of the jet disk, the particular advantage of the shower according to the invention can be exploited for the production of soft massage jets.
  • FIG. 1 There is a hand shower shown from the back.
  • the hand shower has a circular in plan ground shower head 1 with a handle 2, wherein the handle 2 is slightly angled from the plane of the shower head 1, but extends radially to the housing of the shower head. At its free end there is a connection for a shower hose.
  • FIG. 2 shows a cross section through this shower head along a diameter.
  • the shower head or its housing has a rear wall 3 and an outer wall 4.
  • On the side facing away from the rear wall 3 of the shower head includes a jet disk 5, which has a plurality of jet openings through which the shower water emerges in individual jets.
  • a chamber 6 is formed, which has a first directly to the rear wall. 3 has adjacent region, which then adjoins a narrow but enlarged diameter inlet region 7. Starting from the largest diameter formed in the inlet portion 7, the walls of the chamber 6 in the direction of the jet disk 5 inwardly from and thereby form a tapering region 8, which can also be referred to as a funnel with curved side walls.
  • This tapering region 8 opens into a constriction 9, which is arranged opposite the jet disk 5.
  • a bottom 10 is arranged in the housing of the shower head. Between the bottom 10 and the jet disk 5, a jet exit chamber 11 is thereby formed which has a very small thickness but a diameter which is greater than the diameter of the chamber 6 at its largest point, namely within the inlet region 7.
  • a channel 12 is formed outside the upper portion of the chamber 6, which extends a circumference around the chamber 6 along.
  • the channel 12 has a rectangular cross section with rounded edges.
  • the channel 12 on its underside, that is, in the direction of the jet disk 5 side facing an outlet opening 13. Through this outlet opening 13, the water from the channel 12 enters the chamber 6.
  • the channel 12 is what in the Figures 1 and 2 is not shown, connected at its outlet opening 13 opposite end with the interior of the handle 2.
  • FIG. 3 shows a longitudinal section through the shower head in a rotated 90 ° plane in a larger scale.
  • the tapering portion 8 begins at the end of the inlet portion 7 with a shape in which the wall of the chamber 6 is first guided inwardly almost in a radial plane. In other words, the radial plane runs tangentially with respect to the wall of the chamber 6 in the rejuvenation area 8. Die
  • Wall of the chamber 6 in the tapering 8 leads far inward and then passes in a curved arc in the constriction 9, where the tapering region 8 terminates in an opening whose edge extends in a plane parallel to the jet disk 5. At this point, the wall of the tapering region extends in the axial direction, ie perpendicular to the plane of the jet disk 5.
  • a plate 14 is arranged, which has an inclined surface at its outer edge, which has the passing through the constriction 9 Water is diverted radially outwards.
  • a channel 15 is formed, through which the water flows through the shower hose in the shower head.
  • This channel 15 is connected via a line bow 16 with the aforementioned channel 12 in connection.
  • the channel 12 runs, see also FIG. 4 around the chamber 6 over an arc of about 270 °.
  • the outlet opening 13 is formed, which, since the channel 12 gradually moves down there, also has a relatively large arc length, which is here in the range of 45 °. The water leaving the channel 12 through the outlet opening 13 therefore passes tangentially into the chamber 6.
  • a gap 19 which is filled with air but does not fulfill a function. This space 19 is also in the section of FIG. 5 to see.
  • the longitudinal section of the FIG. 6 corresponds to the longitudinal section of FIG. 3 However, shows a comparison with the previous embodiment modified embodiment of a shower head.
  • longitudinal section of the FIG. 6 It can be seen that to the right of the chamber 6 no channel can be seen.
  • the explanation follows from the FIG. 7 , Although the channel 12 extends along a circumference around the chamber 6, but only over an arc length of a quarter arc including the extension of the outlet opening 13. It can also be seen from the drawing that the cross section of the channel 12 downstream Conduction arc 16 is reduced.
  • the longitudinal section through the shower head in FIG. 8 should show that such a massage effect can be achieved with a shower even then can, if the axial extent of the tapering portion is not so short as in the previous embodiments, but takes such a length as the FIG. 8 shows.
  • the axial extent of the tapered region is significantly smaller.
  • FIG. 11 to FIG. 13 an embodiment in which the shower head is an overhead shower, which thus contains no handle.
  • the water inlet happens here through a connecting piece 22 which extends in the axial direction. He is laterally offset from the indicated axis 23 of the shower head.
  • a line bend 26 is formed, from which the water is passed through 90 ° in the channel 12, which then leads around the chamber 6 formed around the shower head again in the same manner.
  • the channel 12 extends here about 180 °, so a half arc.
  • an outlet opening 13 is again present, which points to the beginning 18 of the wall of the tapering region 8.
  • the shower head of the FIG. 11 to FIG. 13 is an example of the fact that the diameter of the jet exit chamber 11 formed between the jet disk 5 and the bottom 10 may even be substantially larger than the maximum diameter of the chamber 6 into which the water is generated a vortex flow occurs. Even with such a large difference between the diameter of the constriction at the end of the tapering region 8 and the diameter of the jet outlet chamber 11, the turbulence of the water also in the outer region of the jet exit disc 5 still leads to a massaging effect.
  • the jet exit disc can also have several areas which can be controlled separately.
  • FIG. 14 shows a view of the hand shower from the user's point of view. So here is the jet disk 5 to see.
  • the jet disc is rotatably mounted together with the bottom 10 of the jet outlet chamber 11 on the outer side of the end of the tapering region 8.
  • an opening is provided, in which a jet core 25 is arranged.
  • the edge of the opening of the jet disk 5 engages in a circumferential groove on the outside of the jet disk core 25. This circumferential groove extends obliquely and forms a curve which cooperates with the edge of the opening.
  • the jet disk core 25 is guided with a shaft 27 in a socket 28 on the inside of the rear wall 3. How to do the presentation in FIG. 16 can be removed, the shaft 27 is formed so that it can not be rotated relative to the bush 28. With a rotation of the jet disk 5, therefore, the jet disk core 25 is slightly displaced in the direction of its shaft 27 in accordance with the slope of the curve in the circumferential groove.
  • the FIG. 15 shows the position in which the inwardly directed shoulder 29 of the jet core 25 abuts against the edge of the outlet opening of the tapering region 8.
  • the jet core has six continuous jet outlet openings 30. In the position of FIG. 15 Because of the relatively large jet outlet openings 30, a hard massage jet is generated here in the chamber 6 due to the water vortex in the chamber 6.
  • the passage openings 30 together preferably have a similar flow cross-section as the jet outlet openings in the outer region together.
  • the beam core 25 Twisting the jet disk 5 by means of the Verstellansatzes 31, the beam core 25 is in the in FIG. 17 moved position shown.
  • the shoulder 29 of the disk core 25 lifts off the edge of the opening at the end of the tapering region 8.
  • the water now flows past the shoulder 29 into the outer region of the jet outlet chamber. Due to the high velocity of the water in the circumferential direction of the rotating vortex jumps immediately to the outside, so that no water exits despite the larger opening cross-section of the jet outlet openings 30 of the jet disk core 25. A seal is not required.
  • the jet core which is displaced in the illustrated embodiment, may also have a different number of jet outlets 30. It is also conceivable that it contains a single central opening.
  • the jet core is axially movable, while the jet disk is formed fixed outside the core. It is also conceivable to move the jet disk as a whole for switching on the various areas of the jet disk.
