Abstract

A hydro-massage nozzle for injecting at least one substance into a water basin helps to generate air bubbles in that the substance enters the water basin over as broad a surface as possible. For this purpose, a jet deviating and distributing plate (1) that deviates the substance to be injected in a direction approximately parallel to the basin wall is connected downstream to the Venturi meter associated with the substance inlet (8).

Description

Hydro massage nozzle for creating an air bubble in a pool of water.

The invention is based on a hydro massage nozzle as disclosed in EP 85108947.4, EP 83630167.1, EP 83112515.8. Such nozzle constructions have the disadvantage that they can only be installed in the side walls of a water basin. When installed in the area of the pool floor, the circulating water would splash onto the ceiling of the bathroom. If the power was reduced, the desired massage effect would be too weak. The known nozzle designs with extensive piping are usually too large to be installed on the bottom of a water basin because such an assembly space is not available under the water basin. The installation in the water pool wall has the disadvantage that the massage effect, which is usually caused by a water-air mixture, only hits the bathing guest laterally, for example in the bathtub, while massage on the back of the bathing guest is not possible. With a nozzle configuration, for example in a bathtub with three nozzles on the right and three nozzles on the left, there is no surface effect, the bathing guest can turn and turn as he wants, his body is not exposed to a full massage. Another disadvantage of known nozzle designs is that the blasted medium (water and / or air) always has a certain jet effect, which can be adjustable in direction, but produces only a small area effect. The known nozzles work on the principle of the water jet pump, with or without the aid of a compressed air generator. Nozzles are known which serve the pure supply of compressed air. Disadvantageously, the compressed air nozzles are distributed in a large number of bores over the bottom surface and walls of the water basin, which naturally leads to sealing problems, the nozzles are not covered, bath water and soap residues can penetrate, which leads to hygiene problems in the supply lines. Such air supply nozzles disadvantageously have no massage effect, but only lead to bubbling of the water, in particular the water disadvantage with so-called bathtub whirlpool pads of a mobile type is known , the higher the jet pressure, the more disadvantageously and quickly the air bubbles rise, which are decisive for the massage intensity.

The invention described below is a further development of the single jet nozzle described in D 3607788.7. Advantages of the invention

By means of the nozzle construction according to the invention, both a multiply distributed water jet and also a multiply distributed jet from a water-air mixture, as well as a multiply distributed air jet, can be injected into the interior of the water basin. It is possible to use and select the two known systems (water jet pump with injection air without or with blower, or only with blower air) with only one nozzle. If initially only one system is desired for the equipment, the other system can be retrofitted at any time by supplying the nozzle according to the invention with the respective medium.

The generated jet of water and / or air is radiated into the interior of the water basin in a broad, star-shaped manner, without splashing water occurring in the vertical direction. Blown-in air does not leave the nozzle in the direction of buoyancy, the higher the jet pressure, the longer it takes for the air bubbles to reach the vertical direction of buoyancy.

Air bubbles, which are blasted in an air-water mixture, naturally get quite far into the interior of the water volume when mixed with water in the water jet until they detach from the water jet and become buoyant. The water-air flow and the associated massage effect is therefore significantly increased.

Instead of 40-80 individual bores in the bottom area of the water basin, 6-8 nozzles according to the invention can cover the entire surface of the water basin with a whirlpool and with a powerful massage effect. The risk of leaks is thus reduced to a minimum. Another advantage of the nozzle construction according to the invention is that it can easily be installed in mobile bath tub mats, which previously could only be operated with a compressed air generating blower. The nozzles according to the invention can also be installed in water basins with a low water level, such as in a foot basin, without the risk of splashing water. Installation is also possible in bathtub inserts. Preferably in pairs and parallel in the bottom of a water basin, which can be a bath tub, the nozzles according to the invention offer the swimmer a wide-area underwater massage, to which the swimmer can comfortably expose any part of the body, by rotating the body can both back, chest and Side part facing the pool floor equipped with nozzles. The penetration of bath water and soap residue is effectively prevented, the jet outlet opening is hygienically covered and closed when the pressure generator (pump, blower) is switched off. The embodiment according to the features of the main claim has the particular advantage that the jet deflecting plate as a lid, on or above the feeder, on the side of the lid facing away from the tub bottom, results in a strong suction effect, which results in enormously favorable water circulation within the water basin, which leads to increased turbulence, which is not only dependent on the known water extraction from the tub and re-irradiation at a nozzle by directional flow, but also acts through lively intermediate flow from the nozzle blow-out direction back to the center of the radiation covered by the cover. The amount of recirculation water mixes again with the amount of radiation at the circumference of the lid and is enriched again with intake air, which is carried far into the tub by this favorable flow. Advantageously, the jet openings according to the invention can be used both on the bottom of the water basin and on the side walls of the pool, the invention enables jet openings which are used, for example, in existing nozzle housings and which can be exchangeably a jet shape of the known type, as well as a jet shape in accordance with the invention allow distracted kind. It is advantageous to install known jet nozzles at the bottom of the water basin, with the beam shaping then being deflected and spread over a wide area, like a fan against the body of the bathing guest. When using the radiation according to the invention in the side walls of a water basin, the massage beam is guided under the body of the bather by the beam deflection in the direction of the bottom of the water basin. This type of water jet guidance according to the invention advantageously brings about a far better massage effect than the previously known punctiform. Charisma. In the case of single-jet nozzles of the known type, it is proposed for the purpose of the redesign to use an extension between the nozzle mouth and the jet nozzle. The extension prevents backwater in the vacuum line. However, the driving jet nozzle can preferably also be provided at a greater distance from the jet mouth, which likewise prevents backwater and the jet deflection toward a slot-like jet opening is favored. The area-wide irradiation according to the invention can advantageously be carried out by. Flat slit-like injection openings are caused, which runs as a slot around the radiation cover or through a plurality of bores or openings which run side by side or through an outlet slot, which releases the round nozzle housing itself after a radiation side. The feeds for the respective media which are introduced directly into the nozzle housing have the advantage that at least one or a plurality of Venturi nozzles form at their upper outlet and as a result far more air is added to the water than is the case with known constructions.

Advantageously, the radiation is directly beneath the cover and distributor plate, which favors the radiation and is radiated into the inner basin without backflow to the vacuum line. With an angle of incidence between 0 - 70º compared to the assembly level, the best beam distribution and mixing results in the best turbulence and massage performance. This angle of incidence has the advantage in particular over designs with a non-return ball inside the nozzle housing that the jet leaves the nozzle housing in the region of the desired angle of incidence and is not necessarily guided in the vertical direction of incidence by the diameter of the ball.

The embodiment according to the features of claims 2 and 3 has the advantage that the initially round propellant jet is guided past the collecting nozzle without reducing the flow speed and is thereby deflected and shaped and blasted into a fan-like or fan-like jet. At the same or high flow rate, the venturi effect is advantageously favored and more suction air is added to the driving jet.

The embodiment according to the features of claim 4 has the advantage that the nozzle body itself forms the Venturi nozzle (s) and is simply inserted into the nozzle housing. If the feed is separate, the media can be fed directly up to the cover and distributor plate. The embodiment according to the features of claim 5 has the advantage that backflow water from the propulsion jet supply line cannot get into the suction line. Bath water cannot enter the supply lines and cause germs in a normal bath (without using the air bubble system); on the other hand, the supply system can be flushed under slight pressure without detergents or circulating agents getting into the indoor pool.

The embodiment according to the features of claim 6 has the advantage that the opening of the jet opening is only open when the pressure generator is switched on and the cover and distributor plate both the propulsion jet nozzle and the suction and / or compressed air supply coaxially with it ) closes. Backwater in the suction and / or compressed air line is avoided. The design according to the features of claim 7 has the advantage that the entire nozzle construction can be manufactured inexpensively from one piece, known multiple housings can be used for connection on the water basin back, complex special constructions are not required, differences in the water basin wall thickness can be compensated for by deeper or less deep screwing of the rear extension into the main feeder. This construction according to the invention results in a particularly stable construction.

The embodiment according to the features of claim 8 has the advantage that the propellant jet supply can be inexpensively manufactured in one piece together with the cover and distributor plate. The opening (s) for the suction air can also be formed on an insertable and exchangeable unit that serves as a nozzle body. Such a unit according to the invention is easily dismantled for cleaning and revision purposes, it can be easily inserted into a known nozzle housing.

The embodiment according to the features of claim 9 has the advantage that the individual components can be joined together by screwing in, in particular screwed into known nozzle housings with an internal thread, or can be used without a thread. The embodiment according to the features of claim 10 has the advantage that the nozzle body is fastened and held within a nozzle housing by a screw or flange ring, the clamping can be designed such that the nozzle body is still movably mounted. The use of a screw ring in a flange-like design has the advantage that the threaded ring on the one hand clamps the nozzle body, but on the other hand spans the edge area of the nozzle housing, so that the surface can be replaced at any time. Advantageously, the flange ring can also be fastened by means of screws, for example the flange ring can be movable within a slot, such a slot, in conjunction with said screw, allows a clearance which serves to open or close air outlets on the nozzle body when the flange ring is rotated. The flange ring preferably carries openings which correspond to the air outlet openings of the nozzle body and which can be rotated via the flange ring. The embodiment according to the features of claim 11 has the advantage that the air supply or air outlet openings can be covered and thus opened and closed by rotating the nozzle body. The configuration according to the features of claim 12 has the advantage that supply of suction air and compressed air takes place through separate channels which, according to the invention, lead laterally into the nozzle housing, without extensions or bridging pieces being used towards the rear main connection. This configuration is particularly advantageous if the nozzles according to the invention are used in water basins with different wall thicknesses and where these differences have to be bridged. The embodiment where the air supply is to be regulated is also advantageous. By simply rotating the corresponding openings towards the feed, the opening or closing of the feed openings can be effected.

The embodiment according to the features of claims 13 and 14 has the advantage that backwater from the propulsion jet supply cannot penetrate into the air supply and that the nozzle openings are closed during normal bathing. If the circulation pressure is low, the supply system can be flushed without circulating agents or cleaning agents being able to get inside the water basin. An elastic seal can advantageously be attached to the circumference of the cover and distributor plate, and attachment or mounting to the nozzle housing is also conceivable. According to the invention, such a seal is designed as an O-ring or as a lip seal or in any other known manner as a seal, the seal opens by pressure, by the circulation pump or by pressure from the fan.

The embodiment according to the features of claim 15 has the advantage that the constriction, which can of course also be an indentation, results in favorable flow conditions which support the venturi effect.

The embodiment according to the features of claim 16 has the advantage

that when the air pressure generator is switched on, the supply of suction connecting main connection line is closed and compressed air cannot escape. In addition, the intake air line is also protected against backwater. The embodiment according to the features of claim 17 has the advantage that the valve body interacts. With water backflow, however, both valves close and the compressed air generator is effectively protected against water backflow. As soon as the fan switches off, the intake air line is cleared again. The line routing according to the invention has the further advantage that intake air does not have to be passed through the blower and the other supply lines. The embodiment according to the features of claim 18 has the advantage that condensate or backwater of any kind can drain from the pressure line, but the float valve closes as soon as the unwanted water has drained and when compressed air is generated.

The embodiment according to the features of claim 19 has the advantage that the elasticity of a seal is used to generate a restoring force. The same force must be overcome for opening, so that with a slight counter pressure of a cleaning agent to the inner basin, no rinsing agent escapes.

The configuration according to the features of claim 20 has the advantage that flat channels can be used where there is no space for a normal pipeline installation, advantageously flat channels can serve as a support and support surface on the bottom of the water basin and the supply of the nozzles with take over the respective media. The embodiment according to the features of claim 21 has the advantage that the feeds for the different media are connected with a single connection housing and only a minimum of sealing risk arises. Such a housing can advantageously bring a plurality of main feed lines to a nozzle.

The embodiment according to the features of claim 22 has the advantage that the manufacture and assembly of the various anti-kickback devices is made possible by a compact design. When the multiple housing is installed, all safety lines and devices are installed at the same time, the line routing is shortened, the sealing and installation risk is reduced, pipe sections into which unwanted bathing water can penetrate are eliminated, the cleaning of the system is simplified and is only limited to the water-carrying part, which can be easily cleaned by rinsing.

The embodiment according to the features of claim 23 has the advantage that if the supply of compressed air or another medium is created, a separate and controllable supply is created which, separately from the other media, reaches the interior of the nozzle body directly. Advantageously, the connecting channel can also accommodate a kickback protection. The embodiment according to the features of claim 24 has the advantage that the kickback protection can at least be opened or at least closed by electrical energy. Advantageously, the air passage can be controlled by upward movement, so that suction air or compressed air is mixed with the jet water and only water emerges from the jet opening. By this Einrich invention Intermittent and pulsating air admixture is made possible.

Further advantageous embodiments can be found in the following description of a preferred exemplary embodiment, the drawings and claims. Show it:

Fig. 1 shows a vertical section through the nozzle construction according to the invention. In the nozzle combination shown in vertical section in FIG. 1, a jet deflection plate 1 is placed in front of the medium exit direction B. The jet baffle plate 1 may preferably be a poppet valve that seals at the peripheral line 2 on the nozzle housing 3. A rubber ring 4 can serve the purpose of sealing, which can have its seat both in the housing 3 and in the beam deflection plate 1. The housing 3 is preferably clamped by a thread 5 to the bottom or the wall 6 of the water basin and shows on the side A in at least one medium supply line 8 via which water or air can be supplied. The medium supplied under pressure lifts the beam deflection plate 1 out of its seat and enters the interior of the water basin 7 through at least one radiation opening 9, but preferably through a plurality of radiation openings. The radiation is preferably parallel to the mounting plane C-F through radiation openings that are arranged radially, tangentially or at any angle between 0-180º to the mounting plane, the radiation can be ring-like, it can be slot-like or through round openings, the radiation can have any shape. Regardless of the first medium, which can be gaseous, a second medium, for example water, can be supplied to the nozzle construction through the opening 10, which is preferably also irradiated into the inner basin 7 through the radiation opening 9. Separate single-beam openings for the different media are also conceivable. If two different media are supplied, one can be used as a propulsion jet, the other medium being entrained in principle by the water jet pump. The principle of the water jet pump is known and need not be explained in more detail. The propellant jet can be guided both via the feed 8 and via the feed 10, the deflection of the

Driving jet from the feed direction A in one or more directions parallel to the mounting plane CD or at any angle to it. The drive jet can be deflected by a conical design fertilizer 11 of the end of the feed line 8 as shown in detail in FIG. 2 or by a conical configuration 13 of the beam deflection plate 1 as illustrated in detail in FIG. 3. Of course, however, the beam deflection can also be spiral, which can be generated, for example, inside or outside the feeder 8.

In addition to the previously described option in which a water-air mixture is generated by the known Bernoulli effect and blasted into the interior of the water basin, there is of course also the option of supplying water and compressed air to the nozzle combination, which means that significantly larger amounts of air are blown in than is the case with the principle of the water jet pump Case is. Thus, three different functions are possible in that only compressed air is supplied to the interior of the water basin, (operation with blower), water can also be supplied with or without injection air (operation with circulation pump), water with injection and compressed air (Operation with circulation pump and blower). The injection air or the compressed air can be supplied in a controllable manner. Both the Bernoulli and Venturi effects can be used to generate the mixture. The jet deflection plate 1 can be rigidly mounted and, for example, a non-return ball or flap or some other non-return device can be installed in the nozzle housing 3, which prevents bath water from entering the supply system.

The beam deflection plate 1 is preferably held by the device 12, which can be a ring, on the stop of the nozzle housing 3, and a screw-in holder is also conceivable. It is particularly advantageous

Arrange inlet nozzle (s) 9 radially-tangentially and use the jet pressure to rotate the jet deflector plate and to swirl the media mixture or media. The mixture of air and water can of course also be generated in front of the nozzle housing 3, in which case the nozzle housing 3 and the opening (s) 9 only take over the radiation into the interior 7 of the water basin. When the propulsion jet is at a particularly high pressure, the media are mixed outside the radiation opening (s) 9 in the direction of the interior of the water basin. The feed 8 can be provided with a non-return device, the curved surface of which is, for example, conical or spherical and serves to deflect the beam. This example is shown in particular in FIG. 3, the cone 13 shown there can be movable and serve to close the feed 8 and, after opening due to the pressure of the medium, the beam deflection. 4 shows a further preferred embodiment for beam deflection. The feed 8 divides at the end into several tubular outlets 9a. The propellant jet can be guided via the outlets 9a or it can be supplied to the interior 7 of the water basin via the openings 10a. This variant is preferably also covered by a cover which can be rigid, movable or designed as a poppet valve. The cover 1 or the poppet valve can of course also be equipped with at least one vertically acting bore for the outlet for at least one of the media. The distributor star can also carry vertically acting outlets 14. Also in the variant shown in FIG. 4, the outlets 9a can be arranged at any angle between 0-180 ° with respect to the assembly plane CF. Of course, in all variants (Fig. 1-4) it is possible to provide the beam deflection plate 1 or the poppet valve 1 with bores from which one of the media or both media or a mixture of both media are radiated. Continuation of the description

5 shows the feed line 8 with a constriction 20 according to the invention on the upper nozzle neck. It is proposed according to the invention to incorporate the constriction as a depression in the feed line 8 and to form it in a ring-like manner. It is further proposed to provide the constriction 20 with openings 21 which create a transition into the interior of the feed 8. According to the invention it is further proposed not to dimension the feed line 8 smaller than Φ 6mm and not larger than Φ 30mm. The constriction 20 should each have a Φ, which corresponds to 50 to 95% of the diameter of the feed line 8. According to the invention, it is proposed to provide the cover 1 with a screw thread, which enables height adjustment, so that the cross section of the outlet opening 9 opens or closes depending on the operator. Of course, it is also possible to open and close the lid 1 by means of a type of eccentric closure, as is known in the case of bathtub drains. Individual nozzles or respective nozzle groups can be operated using a lever or handle.

In an advantageous embodiment, it is proposed to shape the neck of the feed line 8 at the upper end 22 in such a way that an emission angle "a" of between 0 and 70 results. The feed 8 can be open or closed on the top, the beam deflection plate 1 can serve as a cover for the feed 8 and the beam shaping. According to the invention, it is proposed to mold the jet nozzle 23 directly onto the nozzle housing 3 and to adjust and regulate it, for example by means of a screw thread in the interior of the nozzle housing 3. The narrowest cross-section 24 of the jet nozzle 23 should be placed on the constriction 20 in such a way that the cross-section 24 acts in a range of 30 mm before the constriction until it runs out at the upper end 22 and is preferably adjustable within this range. Of course, it is also conceivable to mount the feed 8 or, for example, an adjustable threaded ring in an adjustable manner with respect to the propulsion jet nozzle. The feed 8 is to be fixed in the center of the jet nozzle.

The jet deflection device according to the invention can of course also be designed in such a way that the deflection of the radiation media, preferably a mixture of water and air, which is produced in a known manner, is digitally deflected by an angled jet deflection plate. 6 shows such a device according to the invention. Baffles of this type can preferably also be attached to nozzles of a known type, which are known to be installed in the side walls of the water basin. The radiation can be deflected towards the bottom of the bath and spread widely under the body of the bathing guest. According to the invention, it is proposed to place such baffle plates 50 in front of the radiation in such a way that the radiation takes place either in a straight direction AB or in a deflected radiation direction AC. It is proposed to make the beam deflection plate adjustable so that it either deflects the beam or allows it to emerge unhindered. This task is solved, for example, by a collapsible beam deflector. Several individual outlet openings are also conceivable, which can be opened or closed as desired. FIG. 7 shows an arrangement of a feed line according to the invention, with, for example, a circulation pump 25 and a compressed air generating blower 26, which act individually or collectively on the outlet nozzle 27. According to the invention, it is proposed to assign at least one air intake valve 28 to the outlet nozzles, through which intake air is supplied, preferably adjustable, during operation with a circulation pump, but no compressed air can escape during blower operation. A check valve 29 allows intake air to pass from the ventilation 28 to the nozzle 27. When operating with a fan, compressed air is supplied to the air supply line 30 and the non-return valve 29 closes the line cross section. Preferably, the compressed air generator 26 is also equipped with a non-return device 31, which secures the blower against water backflow. Preferably, each outlet nozzle is 27th assigned its own air intake valve 28. A plurality of outlet nozzles 27 are preferably connected to a central pressure line 3o and equipped with a non-return valve which prevents water backflow in the direction of the blower 26 and only opens when the blower pressure is high. To solve this problem, the feed 8 carries two inputs 33, 34 which serve on the one hand to supply compressed air and on the other hand to supply intake air. Of course, the inputs 33, 34 can also connect to a common connecting line, which leads from supply line 8 to supply line 8 or from one outlet nozzle 27 to the other outlet nozzle 27. In a further advantageous embodiment of the invention, it is proposed to design the non-return valve 31 as a flap valve which, for example, releases the blower air pressure in a burst-like manner and pulsates the supplied air. Of course, however, another device known per se for pulsing the air flow can also be used. According to the invention it is also proposed to arrange a water separator, for example a floating valve ball, between the compressed air generator 26 and the non-return valve 31. The prevailing blower pressure presses the float ball 35 against the seat 36. When the backflow water arrives, the float 35 opens and empties the air supply line from the reflux water and / or condensate. In order to avoid water entering the outlet nozzle 27 during the pump or blower standstill phase, it is proposed to make at least one trumpet-like mouth of the feed line 8 from an elastic material which, during downtimes, rests like a mouth on the wall of the housing 3 and causes sealing. When the pressure generator is switched on, the elastic material is pressed into the desired ejection position and the nozzle mouth is released. Of course, it is also conceivable to manufacture the baffle plate 1 or certain partial areas of the cover plate from an elastic material which, when the pressure generator is switched off, serves the purpose of closing the nozzle orifices. Continuation of the description

Fig. 8 The nozzle housing 3 is clamped to the pool surrounding wall 6 with a flange-like collar 52 and a thread 5. The thread 5 preferably opens at the back of the water basin into a multiple main feed connection 82 via which the various media are supplied. The nozzle housing 3 has a bore in the center which is designed as a propulsion jet feed 8. On the one hand, it carries a connecting shaft 53, which preferably opens into the main feed line 51 via a screw thread, and, on the other hand, a boundary wall 54 which carries a plurality of bores 9a and in their recesses The cover and distributor plate 1 forms or accommodates the inner pool 7 and, on the one hand, covers the bores 9a towards the inner pool and distributes the beam below the cover and distributor plate, preferably through a conical shape 11, and to the circumference of the cover plate toward the inner pool, deflects approximately parallel to the bottom of the pool and shines within the angle described. At least one further opening 10, preferably in the form of one or more bores, is made coaxially with the bores 9a and leads into the main feed line 33 for the second medium. A plurality of bores 10 can also open into the main feed line 33. The nozzle housing 3 preferably carries a further opening 55 which opens into the main feed line 58, 30, 34 for a further medium, preferably compressed air is supplied via this opening 55 and suction air is conducted via the opening 10. The feed 8 preferably carries a non-return device 59 which prevents bath water from entering the main feed line 51. A ball can also serve as a backflow preventer, a spring-loaded backflow preventer is also conceivable, or a lip seal or flap device can be selected, which only opens when pressure is exerted on the backflow preventer and the accelerated propellant jet in the direction of the nozzle mouth 9 leads to the backflow. Fuse opens. Such backflow safeguards are widely known, a design description is therefore not necessary. The opening (s) 10 preferably lie in an annular groove 60 which is designed as a depression. Preferably, the back of the nozzle housing 3 also carries a groove 61 as a depression for the opening approaches. In the known way to the jet opening 9, the propellant jet takes along with it the portion of the second medium known as the catch jet, whereby a water-air mixture is formed. The irradiation to the inner pool 7 takes place on the circumference of the cover and distributor plate 1, 50. Compressed air is preferably supplied via a separate pressure generator 26. Compressed air can be supplied without the use of a circulation pump, but it is also possible to use a circulation pump to generate the driving jet and additionally a pressure generator to generate compressed air. The openings 10, 55 preferably also carry non-return devices 86 of the type described above. A common non-return valve 4 is also conceivable, which is preferably located in the vicinity of the irradiation opening and which covers all the existing openings and only opens when there is appropriate counterpressure. Fig. 9 shows an embodiment in which the cover and distribution lerplatte 1 is movably mounted. The feed 8 preferably carries at its upper end a shoulder 12 which serves as a holding bearing for the cover and distributor plate 1. The part pointing into the feed 8 carries the counter bearing 62 which can consist of a locking ring. The configuration is particularly advantageous if the opening (s) 55 are arranged coaxially to the central axis of the feed 8 in such a way that the propellant jet flows through the cover and distributor plate 1 only when the cover and distributor plate 1 is in the raised position, and preferably through a closure when the cover plate is held down in the form of a paragraph 63. Of course, it is also conceivable to move a valve seat when the cover and distributor plate 1 is held down in such a way that the inflow of the propellant jet from the feed 8 is interrupted. This is achieved, for example, if a sealing device is guided through the back of the movable cover and distributor plate against a sealing seat, which closes the feed 8. As soon as the pump pressure is switched off, the valve seat closes, which can be, for example, an O-ring or a lip seal, a cylinder or plug valve, which is pressed down from the cover and distributor plate. The closing force of a spring can also be used, the weight of the cover and distributor plate also supports the valve closing process.

FIG. 10 shows a hydro massage nozzle according to the invention, in which the nozzle body 64 with supply jet, compressed air and suction air supply is inserted into a nozzle housing of the known type. The nozzle body 64 is held in the nozzle housing 3 by a screw ring 65 (left side of the illustration) or by a flange ring 66 (right side of the illustration). According to the invention, it is proposed to screw in the nozzle body 64 via a thread 72 or to clamp it tightly with the screw ring 65 or flange ring 66. The flange ring 66 can additionally serve as a cover plate, preferably with a tempered surface, for the flange 52 of the nozzle housing 3. It can be clamped to the nozzle housing 3 by a thread 67 on its inside or by a thread 68 on its outer circumference. Fastening by means of holding screws 87 is also possible. In a preferred embodiment variant, the flange ring 66 has openings which are arranged symmetrically and congruently with the openings 10, 10a, 55 of the nozzle body. By rotating the flange ring, the openings are shifted towards each other, or opened or closed. To do this, the flange ring only needs to be rotatably mounted. The rotation range can be all-round, but it can also be a small rotation range can be used (right, left). The nozzle body 64 inserted into the nozzle housing 3 establishes a connection to the main jet feed line 51 via the feed 8 with its extension 53. The openings 10, 10a 55 provide a connection to the / the main feed lines 30, 33, 34, 58 for compressed and / or suction air, it can be used as a connection between the respective main feed lines a simple wall opening 74, 75 in the form, for example, one Bore, serve. If two different main air supply lines 58 for compressed air and 34 for suction air are separated to the openings 10, 10a and 55, an extension can be used, for example, which extends the space between the end of an opening 10, 10a, 55 up to the wall opening in the main supply line 34, 58 bridges. In this preferred way, a certain type of air (compressed / or suction air) arrives directly from the respective main supply line 34, 58 through said extension to the corresponding opening 10, 10a, 55. According to the invention, it is proposed that the cover and distributor plate 1 together with the To mount the nozzle body 64 rotatably in the nozzle housing 3 and to assign a projection 70 to the openings 10, 10a, if necessary 55, on their side facing away from the basin inside 7, for example in the form of a nose or a shoulder, which depending on the rotational position has access to at least one opening blocked. Such a lock can of course also be arranged between the nozzle body 64 and the multiple housing 82 or housing chamber 71.

FIG. 11 shows a multiple housing 82 known per se with the main feed connections 58, 34, 51 for the various media. In the housing chamber 71 with the internal thread 72, the nozzle housing 3 engages with its off thread 5. A connection 73 is preferably provided centrally, which leads as a breakthrough to the main jet feed line 51 and into which the feed 8 engages with its extension 53. The main line 34 with the opening 74 serves for the supply of suction air, the connection 58 serves for the supply of compressed air. The suction air passes through the opening 74 into the housing chamber, from there to the opening (s) 10, 10a, 55 and further to the radiation opening 9.

The invention offers two different connection options for the compressed air. 7 shows an embodiment in which the blower 26 is connected to the nozzle unit via the line 30, 32 and the connection 33, and suction air is supplied to the nozzle unit via the connection 34. Compressed air and

Suction air then reach the jet opening as described above. The second variant (FIG. 11) shows a closed compressed air duct up to the outlet of the inlet 55. Of course it is possible to use compressed air and suction To bring air together in the housing chamber 71, only the wall opening 75 needs to be opened. The wall openings 74 and 75 are preferably each provided with a non-return device to prevent compressed air escaping and backflow water escaping. The wall opening 74 has a non-return device 29, which is opened by vacuum from the Venturi nozzle. The rucksack protection closes at blower pressure and backwater. The backflow protection 31 of the compressed air line opens only when the blower pressure is appropriate, otherwise it is preferably closed by the pressure of a spring. The kickback protection is therefore in constant interplay, depending on the type of air supplied (compressed air or suction air) one of the valves is always closed while the other is open.

In the refinement of the invention, it is proposed to assign at least one of the air-carrying supply lines, preferably the compressed-air-carrying supply line, to a water separator 76 within the multiple housing 82. A float ball preferably opens the outlet 77 as soon as backwater flows into the compressed air supply line. At blower pressure, the float ball 35 is pressed against the valve seat 36 by air pressure and the drain is closed. Of course, a solenoid valve or any other known drain device is also conceivable at this point, which when entering

of water into the pressure line or the S-line, the drain opens.

According to the invention, it is proposed to also equip the drive jet feed line with a water separator of the type described above, in order to empty the system of residual water to the sewer after the bathing operation with circulating water flow. In a further advantageous embodiment, it is proposed to place the air inlet into the nozzle body 64 in its radial area. According to the invention, it is proposed to provide a supply opening 79 in the threaded neck 78 of the multiple housing 82, which corresponds to an annular groove 80 on the nozzle housing 3 and which leads to at least one medium supply opening 10, 10a or 55 via at least one opening 81 in the radial region of the nozzle body. In the threaded neck 78, the supply opening 79 connects to the compressed air main supply line 58. The annular groove 80 can of course also run inside the threaded neck and lead to a counter opening on the side of the nozzle housing 3. In the refinement of the invention, which is both an advantageous embodiment and a separate invention, it is proposed to provide the kickback safeguards which are arranged within the multiple housing with an electromagnetic lock. The main feed line 51, 58, 34 or all main feed lines bear on their outer umm Socket wall 82 which is formed by the multiple housing, an electromagnet 83, the actuating force of which acts into the interior of the multiple housing and there opens and / or closes the non-return devices - as valves. The actuating force can be transmitted by a lifting rod 84, at the end of the rod a seal is guided against a valve seat. The respective main feed line preferably carries an immersion sleeve 85 which is surrounded on the outside by the electromagnet and which guides the lifting rod in the interior of the multiple housing. The working path of the electromagnet can be used in the direction of the valve "open" or in the direction of the valve "closed", it can be used on the compressed air side and it can be used on the suction air side.
