Description

State of the art

The invention relates to a water basin with an air bubble device according to the preamble of the main claim. Such water basins with an air bubble device are used for massage purposes, water basins being understood to mean a hand or foot basin, a bathtub, but also a whirlpool or a larger basin. The massage effect is achieved by an air and / or water jet, which is introduced into the water in the water basin through appropriate nozzles. 'On the one hand, the water in the water basin is moved and animated, and on the other hand, the body parts exposed to this jet are massaged.

In these generic water basins with an air whirlpool device, which are known in many different ways, the water is drawn off from the interior of the basin by a pump and reinserted into the interior of the basin for jet generation via the water nozzle. In principle, the air is carried along with the water jet pump or blown into the interior of the pool via a fan.

In order to supply air and water to the individual nozzles, extensive pipe routing is required around the water basin, which requires a considerable amount of space. Since mostly air and water nozzles are assembled into a unit, connecting pieces for air and water must be provided on the inlet side of the nozzle, to which the pipes or hoses are then connected, which poses a considerable risk of constant leaks. In many cases, the connection points of the nozzles are no longer accessible from outside the basin after the water basin has been installed, so that any leaks can only be remedied if the entire basin is removed.

In a known water basin of this type (US-PS 4233694), the nozzle is used on the inside of the basin and clamped on the outside of the basin, the nozzle-receiving bore in the basin wall is sealed, on the outside of the basin a T-piece is mounted on the nozzle, which leads into the nozzle and is switched on in a pipeline surrounding the basin. As can also be seen in this example of a known water basin, such a piping and nozzle installation disadvantageously requires a considerable amount of assembly time, quite apart from the cost for the large number of small assembly parts. Each of the individual sealing points brings with it the risk of leakage, which is further promoted by the constant temperature changes in such water basins. These known systems have the disadvantage that the lines have the smallest possible cross section due to the required construction volume exhibit, on the one hand high flow losses arise and on the other hand the elasticity of the system is low. The water flowing through the pipe installations cools down quickly and must be reheated before it is radiated back into the interior of the bridge.

Düsengehäuse verwendet, das direkt in ein Pumpaggregat angebaut ist.

bekannten Düsenkonstruktionen, so auch (U.S. 3.297.o25) haben den Nachteil, daß diese entweder in aufwendiger Kleinarbeit mit hohen Dichtungsrisiken in ein Rohrsystem integriert werden oder mit einem unhandlichen Pumpaggregat in Verbindung stehen. Ein weiterer Nachteil besteht darin, daß Badewasser-Rückstände und Seifenreste in das Rohr- oder Kanalsystem eindringen kann, was zu äußerst unerwünschten Auswirkungen führt. Als weiterer Kachteil zeigt sich, daß Düsen bekannter Bauart einen runden, punktartig auftreffenden Massagestrahl erzeugen, wodurch natürlich die gewünsche Flächenwirkung einer Massage nicht erreicht wird. Die Strahlausformeinrichtungen sind nicht tauschbar, beispielsweise zur Ausformung eines fächerartigen, sternförmigen, rotierenden Strahls usw. Bekannte Düsen sind ausladend groß und können daher nicht eingesetzt werden in ein Kanalsystem, sie kennen nicht genutzt werden bei einem als Inneneinsatz dienenden Becken, wie diese zur Sanierung vorhandener immobiler Altbecken Verwendung finden. Kachteiligerweise besitzen bekannte Düsen auch keine Strahlverteilung, sodaß eingestrahlte Luft auf dem kürzesten Wege, ohne Breitenwirkung, zur Wasseroberfläche aufsteigt.In a known nozzle construction (US 3,336,921 and US 2,738,787)

Nozzle housing used, which is installed directly in a pump unit.

Known nozzle designs, such as (US 3,297.o25) have the disadvantage that they are either integrated into a pipe system in complex, small work with high sealing risks or are connected to an unwieldy pump unit. Another disadvantage is that bath water residues and soap residues can penetrate into the pipe or sewer system, which leads to extremely undesirable effects. Another caching part shows that nozzles of known design produce a round, point-like massage jet, which of course does not achieve the desired surface effect of a massage. The jet shaping devices are not interchangeable, for example for shaping a fan-like, star-shaped, rotating jet, etc. Known nozzles are protrudingly large and can therefore not be used in a duct system; immobile old pool find use. Unfortunately, known nozzles also have no jet distribution, so that the air blasted in rises up to the water surface in the shortest way, without any effect on width.

Advantages of the invention:

The water basin according to the invention with the characterizing feature of the main claim, in which channels a) are formed quasi as in the basin wall cavities or b) are formed by channel-type cavities placed on the basin wall, has the advantage that almost no sealing processes occur and the connection points, if necessary can be placed in such an area that is easily accessible for revision purposes. The nozzles can either be built into the channel or used from the inner pool. To the outside, only the connections to the pressure generator are then required. The water and / or air outlet openings can be produced in a simple manner after drilling through the basin wall, the bore in the basin wall itself can serve as an outlet nozzle; a separate nozzle housing is not necessary in this simplest embodiment. Additional nozzle parts can be inserted directly into the channel through the hole in the pool wall.

The channels can be flat and, due to the wide pool wall available, can be chosen to be correspondingly wide, so that a large passage cross-section is provided despite the small volume application.

The channels can be preferably obtained by the fact that the non-k through the pelvic _e nwand channel wall formed by prefabricated be formed and patch half-shells. Gluing, screwing, welding, etc. is conceivable. Naturally, it is conceivable to incorporate the channels directly into the pool wall using a manufacturing process, for example by laminating pipes. In the case of cast basins, the channels can also be cast in, for example in the manner of a melting process, as is customary in casting boiler construction. The production of the channels is particularly advantageous if, according to the invention, a melting mass, preferably wax-like, is used. The later channels are modeled on the pelvic body, the modeling and enamel mass corresponding to the later channel cross section. In this way, very simple molds and half-shells can be made for channel production. It is also possible to coat the applied modeling clay. In the production of the channels from plastics, it is proposed according to the invention to use or at least to initiate the heat development released during the hardening process of the plastics for melting out the modeling compound. Heating rods can also be inserted into the melting mass, which are removed again after the melting. It is also conceivable to produce the cavities and channels from thermoplastic materials or from metal and, for example, to use parts which have been prefabricated to shape the channels. Pipes, hoses or pipe parts of various shapes can also be used for sewer production, with additional overlamination with GRP increasing durability and tightness. Of course, it is also conceivable to obtain the channels by placing such limiting parts which cover and cover the channels and which can also accommodate nozzles, on the inside of the pool wall. As a result, the tightness requirement is significantly reduced.

The embodiment of the invention with channels accessible from the inner basin has the advantage that when the manhole cover is removed from the water basin interior, no outward-facing seals have to be loosened, channels, nozzles can be easily cleaned and possibly also replaced.

The design of self-contained channels that are clamped to the pool wall is particularly advantageous. Such prefabricated units can serve both the water and air supply, they can at least partially accommodate parts of the outlet nozzles, they can form mixing chambers for producing a water-air mixture, and they can carry the connections for water and / or air, which then only have to be connected to at least one pressure generator. Such prefabricated units with at least two outlets to the inner basin save any type of line installation, the units are simply clamped onto the basin wall and connected to the pressure generator (pump and / or blower). A flange-like screwing part, which is inserted from the inner basin, is preferably used for clamping, which is threaded into the channel outlet opening takes hold. Such units can of course also be designed with a large number of outlet openings. The units are interchangeable, they can be used in particular with existing bathtubs, in which the space between the tub wall and masonry is often too small to accommodate a known pipe installation. To convert an existing Altbadewanne only the outlet ports need in the Altwanne be cut, the Kanaleinlilit may be the built-in trough and onto the well back and be pushed to the A _u sschnittöffnungen, the fixing is carried out by screwing of the inner tub, as previously described.

It is possible to design the water basin according to the invention with air and / or water feeds in such a way that once only air and once only water is radiated into the inner basin or that a water-air mixture is generated within the supply lines or within the nozzles and this into the Indoor pool is irradiated. The channels and lines serving the purpose of water and / or air supply are preferably arranged so that they empty themselves after using the water basin.

The air channel can be inverted within the water channel or the channels can extend toward or running side by side, of course, can be used in this construction for pipes or hoses, thereby WE _n can igstens a tube or hose in a channel. The channels can of course also be combined with pipelines and hoses, for example in that the water-carrying cavity runs in the basin wall and the air-carrying cavity is formed by a pipe or a hose that runs outside. A channel that only serves to hold a pipe or a hose is also conceivable, such a channel being able to run, for example, between an old pool and an insert pool.

The embodiment of the invention with ventilation to the upper edge of the pool has the advantage that the air can be drawn in to form air bubbles. The air duct is preferably designed such that when a blower is used, it will not be flooded. The ventilation can also take place via a regulating valve, so that the amount of intake air can be controlled. The installation of an additional non-return valve has the advantage that bathing water cannot penetrate the ventilation line if there is a back pressure.

The design of the water channel with an air supply nozzle has the advantage that air can be supplied to the water channel at almost any point, it only needs to be provided with an air inlet. The transition point at which one medium enters the other medium is designed as a nozzle, which works in principle as a water jet pump, and both water and air can serve as the propellant jet. The principle of the water jet pump is known and therefore need not be dealt with here. Both the Bernoulli effect and the Venturi principle can be used. The effects result in each case between an inner nozzle and a jet nozzle which is arranged towards the inside of the water basin and serves to shape the jet.

The regulation of the flow rate has the advantage that each nozzle can be adjusted individually and, if necessary, shut off. In the simplest embodiment, it is therefore proposed that the opening made as a bore in the basin wall, which may be a water and / or air outlet opening, preferably be provided with a thread, via which a ring acting as an outlet nozzle can be screwed in and out. The inner bore of the ring is preferably conical in shape. The possibility of regulating this adjustable nozzle construction can extend to the outlet of water without admixture of air, up to the maximum admixture of air and beyond to shut off one or both media. It is also proposed to design the water and / or air outlet opening to be pivotable and directionally adjustable towards the inner basin, it being particularly advantageous to design the outlet nozzle both in terms of quantity and direction, the shut-off can be done manually or by an independent check valve, for example, or by a device controlled by external energy, such as a solenoid valve.

An embodiment according to the invention is also conceivable, for example, in which the channels would be formed by a double-walled design of the entire basin. Such a double-walled design arises in particular in accordance with the characterizing features of claim 2. In this way, any type of existing immobile old pool can be converted into a "bubble bath" by using a water pool, such as those used for the renovation of existing old bath tubs, i.e. without removing the old pool and without removing existing tiles, etc. as an insert in the old pool is, any type of cavities between the immobile Altbekken and the insert pool can be used for water and / or air guidance. Due to the small spatial extent of the channels according to the invention, a water pool according to the invention can be installed as an insert with little space loss in any existing old pool. The channels, hoses and pipes that serve to supply the media water and / or air can preferably be in a PU foam embedding that forms a stabilizing effect between the immobile old pool and the insert pool, another type of filling compound is also conceivable. Any type of water and / or air ducting can run in recesses within the intermediate layer between the old pool and the insert pool. The immobile Altbekken or another double-walled construction can have wall and / or floor cutouts in which supply lines for water and / or air run to the pool jet nozzles, these cutouts have the particular advantage that that even very narrow immobile old pools can be equipped with the water pool according to the invention without any significant loss of space towards the indoor pool.

The configuration according to the characterizing feature of claim 3, in particular in connection with the insert basin with at least one connection for one of the media on the inside of the water basin, has the advantage that no consideration has to be taken of the often too limited space under a water basin, on one Connection on the inside of the pool can advantageously be connected, for example, to a fan that is flood-proof and easy to maintain. The embodiment of the invention according to the characterizing feature of claim 4 has the advantage that water and / or air is supplied to those nozzles which are arranged in the region of the pool floor. The invention enables nozzles that do not go beyond the inner surface of the pool wall, for example formed only in the form of a hole in the pool wall, so that the bather does not disturb nozzle bodies protruding from the wall. According to the invention, it is proposed to use the channels and pipes in whirlpools equipped with a filter and water treatment system to return the filtered water to the inner pool and to use nozzle combinations in the water return channels, which generate a water-air mixture and this in the area of Blast the pelvic floor into the indoor pool. The use of the removable duct parts according to the invention, which is mounted as a multi-jet unit under the bottom of the whirlpool, is particularly advantageous. However, incorporated channels can also be used.

By returning the circulating water to the area of the pool floor or its subsequent vertically running edge area, there is better water circulation in the indoor pool, the air supplied in the floor area brings about a better water revitalization and penetrates the entire pool water during buoyancy. The arrangement of nozzle combinations (water-air) for producing a water-air mixture in or near the bottom area of the water basin has the advantage that an additional fan for producing a floor bubble is not required. According to the invention, it is therefore proposed to also equip water basins of the known type with nozzles which generate and radiate a water-air mixture in the basin area.

The embodiment according to the features of claim 5 has the advantage that nozzle constructions can accommodate interchangeable inserts which serve a multiform radiation. It is possible to choose, in addition to the well-known round, point-like massage jet, jet shaping nozzles that allow a fan-shaped, star-shaped, rotating, radially deflected or multi-jet shape, etc., so that, depending on the desired effect, the desired jet shaping nozzle can be used from the inner pool can. The outlet nozzle can with a slit-like outlet for water and / or air formed for generating a fan-shaped beam be, it being possible for the outlet preferably at least rotatable about 9o be ^0, preferably the Strahlausformung should also be directionally adjustable.

Such an embodiment has the advantage that the slot-like outlet generates a wide massage jet, which acts like a fan and emerges once in its width and once in its narrow side by rotating the outlet nozzle. According to the invention, it is proposed to also design this nozzle construction in a quantity-controllable manner, preferably also to store it in a rotating manner, and to guide it in a nozzle holder that is exchangeable. The design of rotating nozzles has the advantage that even larger parts of the body can be exposed to such a continuously moving jet. Such nozzle inserts for different jet shaping can of course also be used in water basins of the known type.

The embodiment according to the feature of claim 6 has the advantage that the water and / or air outlet opening is only open at the time of massage operation and on other occasions undesired soap and other bath water residues cannot penetrate into the supply system. The adjustment option is for individual adjustment.

The embodiment according to the feature of claim 7 has the advantage that the water-air distribution takes place more intensively, air particles are introduced deeper into the inner pool, the massage jet is therefore softer and more pleasant.

The embodiment according to the feature of claim 8 has the advantage that much more air is blasted into the inner basin by beam superimposition than is the case with a simple jet generation _. For example, an additional _. axially guided water jet serve to open a check valve. This device according to the invention can of course also be used in any type of known water basin.

The embodiment according to the feature of claim 9 has the advantage that individual _n e nozzle can be individually opened or closed. This facility can also be adopted in known water basins.

The embodiment according to the features of claim 10 has the advantage that, particularly in the case of air supply, instead of a plurality of individual nozzles with a vertical air outlet, a few individual nozzles with a broad effect can be used, the whirlpool center achieving a particularly strong massage effect. Instead of usually 4o - 6o individual bores for individual nozzles, only 6 - 8 nozzles according to the invention, each with radially deflected or watering can-like radiation, are much cheaper, fewer sealing points are created, the massage effect is further enhanced by rotation of the outlet jet, and a cover valve can be used here Serve rotor, a separate rotor with a fixed lid is also conceivable. The cover valve can serve as a backflow protection. Of course, this device according to the invention can also be used in water basins of the known type.

The configuration according to feature 11 has the advantage of keeping the water and / or air supply lines free of germs.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS: In the water basin shown in cross-section and in longitudinal section in FIGS. 1 and 2, a channel system with cavities for water 3 and air 4 is formed by the basin wall 1 and with this boundary part 2 connected from the outside. The cavities 3 which serve to guide the water are supplied with water under pressure by a pump (not shown) or by a water supply network via a central line 5, in the former case the pump taking the water from the interior 6 of the water basin or from a surge water tank (not shown) . The cavities 3 which serve to guide the water can also consist of several sections, each section being assigned its own inlet connection with at least one jet nozzle for water and / or air. From the cavities 3, the pressurized water is blasted into the inner pool via the nozzle 13, which is arranged below the water level of the interior 6, in the pool wall 1. The nozzle 3 can be formed by a simple bore in the basin wall 1, it can be further developed in many ways, for example as a flange 9 which projects into the channel 3. The flange 9 can be fastened both in the basin wall 1 and, for example, by a device inside the channel 3. The nozzle 13 can be formed by a ring lo, which preferably has a conical inner bore, which can be adjusted within the bore in the basin wall 1 or the flange 9. The nozzle 13 can be held and guided by a carrier 14, which enables axial adjustment until shut-off for the purpose of quantity regulation, allows beam deflection in different emission directions, and the interchangeability of different nozzles for the purpose of beam shaping (round, fan-shaped, rotating, star-shaped, etc .) enables.

With the large number of possible configurations of the nozzle 13, the different variants always have the common feature of protruding with the rear end 13A into at least one channel 3 or 4 or feed line.

Coaxial to the nozzle 13, the nozzle 11 which carries the second medium, which is the inner nozzle and preferably serves as an air nozzle, points into the channel filled with water 3 in. The nozzle 13 works together with the nozzle 11 in the manner of a water jet pump. However, it is also conceivable to use a nozzle construction which only serves to discharge air, and of course only one medium supply line as a channel, hose or pipe is required.

In Fig. 1 two variants of an embodiment are shown side by side. In the variant shown on the right, the extension of the air supply nozzle 11 is connected via a hose 26 to the supply air valve 27, which is inserted into the upper edge 28 of the water basin. The air intake valve 27 can be designed as a regulating valve in order to throttle intake air more or less or to interrupt the air supply. A blower can of course also be connected to the feed line 26, which feeds compressed air to the nozzle 11. The blower can either be arranged under the water basin or, instead of the supply air valve 27, can be arranged on the upper basin edge or in the edge area 33. The regulating valve 27 can preferably be designed as a check or solenoid valve.

A variant is shown in the left half of FIG. 1, in which the limiting part 2 covers a water-carrying cavity 3 and an air-carrying cavity 4. The two channels 3 and 4 are separated only by a web 3 ₀ , which can of course also be formed by the pool wall 1. The limiting part 2 is connected to the basin wall 1 by the web 3o. In this variant, the nozzle 13 is shown as a bore in the basin wall 1 and the extension of the air supply nozzle 11 attached to the limiting part 2 projects coaxially into the bore in the basin wall 1 used as a nozzle 13. In this variant, in contrast to the first variant, the air supply nozzle 11 is extended by the connecting part 31, which connects the air nozzle 11 to the air-guiding cavity 4, which also has an air intake valve 27 in the upper edge of the pool 28. Basically, this variant works like the other. Once the extension 31 of the air supply nozzle 11 penetrates the web 3o and leads into the cavity 4, in the other variant the extension of the air supply nozzle 11 on the boundary wall 2 penetrates the channel wall and continues in the hose 26. Instead of the hose 26, of course, it can also a channel or a pipe are used.

In Fig. 1, a further line 32 is indicated below the water basin, which gives an indication of a further variant of the air duct. This is because the air supply can also be brought about by an air pressure-generating blower and then introduced from this central point 32 of the air supply nozzle 11 or into the cavity 4, in which further air outlet openings are inserted. As a result, significantly larger amounts of air can be blown into the water basin than is possible with the water jet pump principle. Of course you can too serve a simple hole in the pool wall 1, a flange with connection of a connecting hose or connecting pipes are also conceivable for air supply. It is also conceivable that air blown in under pressure serves as the pump medium and water is entrained, namely according to the Venturi principle, as is used, for example, in liquid atomizers. The air can be carried out axially and the water can be guided coaxially or vice versa. Water can be guided in the air duct and vice versa.

In the water basin shown in vertical longitudinal section in FIG. 2, the cavities 3 and 4 of the second variants can be seen in the x-ray image. The two cavities, of which the lower one is preferably filled with water, are separated by the web 30; the upper cavity 4 is ventilated by the valve 27.

3, 3A and 4 further exemplary embodiments are also shown in cross section and in vertical longitudinal section, a water basin according to the invention serving as an insert 38 for an immobile water basin 39. This type of modernization is typical of bathtubs in which an expansion of the old pool is too expensive and the insert pool 38 is only inserted into the old pool 39. The connections for air and / or water can be made through the openings in the old pool or through additional bores through which the supply lines are led. In the case of relatively small old pools, openings 8 can be cut out in the old pool 39, in which the channels 3 and / or 4 run. Of course, old basins 39 can also carry bores or cutouts at several points through which one or more connecting pieces 32 can be led to the insert basin 38 according to the invention, preferably flexible hose lines are used for this purpose, which can run in a plurality to individual inlet nozzles or from individual nozzles Can lead single nozzle. Cut-out bores and openings 8 in the old basin 39 can lead to the insert basin 38 any kind of supply lines from the space under the old basin, it can be used in the insert basin 38 nozzles for air radiation, for water radiation and combined water-air nozzles. The nozzles can be connected individually, for example via hose or pipelines, or they can be connected to a communicating hose, pipe or duct system. Any type of cavity between the old pool 39 and the insert pool 38 can be used for channel production, it is conceivable, for example, to blow air into the cavity between the old pool 39 and the insert pool 38 and in this way lead it to the inner pool 6, for this purpose only the edge of contact is required to be sealed between the old pool and the insert pool. The connection of the insert basin 38 with a water and / or air supply from the inner basin is possible via the connection 33. Such pools, as well as any type of new pool, can have moldings 40 to reduce the water volume, behind which the cavities 3 and / or 4 and the supply lines run. For old pools with cutouts 8 the insert pool 38 is statically supported and held at least in partial areas by the sides and / or bottom walls of the old pool.

3A shows a cross section through a closed channel unit placed on the basin wall 1, which is connected to the inner basin 6 via the common opening 47 in the basin wall and in the attached unit 77. The nozzle body 35 preferably clamps the unit 77 to the pool wall 1 via a screw thread. The unit 77 carries on the back connecting pieces 5, 32 for the media. The unit 77 is connected to the water basin with at least two outlet openings 7, and the outlet openings can be made in any shape (circular, in a straight direction side by side or one above the other, also in two rows and in parallel).

In Eig. 5 shows a further variant of the assignment of the cavities 3 and 4 with a correspondingly different nozzle combination. In this variant, an intermediate wall 34 is guided between the channel boundary part 2 and the pool wall 1. The specially designed nozzle body 35 penetrates the basin wall 1 and the intermediate wall 34. It has 4 radial openings 36 in the region of the cavity, through which air is sucked in and entrained according to the Bernoulli principle or is supplied through the air under pressure. With this nozzle body 35, the water is guided axially out of the cavity 3 via a constriction 49 provided in the nozzle body, which forms the jet. Reverse air and water guidance is also possible, that is to say that water is blown in via the radial openings, which can also be ring-like openings, which water is blown into the inner basin with the entrainment of air. With this device the water gets a swirl. In this variant, too, it is possible to regulate the flow rate of the type already described, and to replace beam shaping devices and beam deflecting devices.

6 shows a further variant of the duct system according to the invention, in which the basin wall 1 forms the outer boundary wall of the cavity 3. A removable plate 37, in which the water and / or air outlet opening 7 is arranged, serves as the cover part of this channel. Other components of the nozzle combination can also be included there. The plate 37 can itself be the carrier flange of one or more nozzles. In this embodiment, too, the air line can be laid within the cavity 3.

As on the sides of the water basin, a corresponding cavity with a removable cover, as indicated in FIG. ₆ , can also be provided on the bottom. It is also conceivable that this cavity serves instead of the water supply for the air flow and that water is supplied via lines or that two channels run side by side, which are covered individually or together by appropriate covers to the interior of the water basin. Of course, only one of the media, air or water, can be fed to an outlet nozzle.

The variant shown in FIG. 7 carries channels 3 and / or 4 of flat design below the pool floor. In this example, two channels 3 are provided for the water flow and channel 4 for the air flow in between, the connecting pieces 31 being used to connect the cavities 3 above the water flow arranged water and / or air outlet openings 7 are supplied with air from the channel 4. The channel 4 can be ventilated via a line 26 to the tub edge. Of course, such floor nozzles can also be used with pipes and hoses 26 in accordance with FIG. Fig. 1 right variant, individually connected.

Fig. 8 shows a nozzle combination, the water is supplied through the channel 3. At the nozzle outlet, a device 56 is provided which acts as a check valve. The non-return valve opens by pump pressure and closes automatically, the resetting can be done by the force of a spring or by the flooding of the bath water, which acts as soon as the pump pressure is switched off. The check valve 56 can be designed in such a way that it blocks both the water outlet from channel 3 and the air outlet from channel 4 or at least one of the outlets. With this construction, the media water and / or air can of course also be supplied via a pipe or hose line. The flow rate can also be regulated by means of the device 56 in that more or less cross-section is released. The device 56 also acts as a baffle plate and widens the emerging water jet, which improves the mixing of air and water and reduces air bubbles. The device 56 can be held by a carrier flange 9, the device 56 is preferably attached to a steering beam insert which can be exchanged for the purpose of different beam shaping.

In Fig. 9 a nozzle combination is shown, which in turn is fastened in the pool wall 1 and is formed by the nozzle body 35, which on the one hand carries radial openings 43 for the water inlet on the inside of the pool and on the other hand an inlet 42 for air on the side facing away from the inner pool owns. Compressed air is fed to this nozzle via the inlet 42, the water entering through the openings 43 is carried along in the manner of the Bernoulli principle and immediately flows back into the inner basin. This nozzle construction can of course also be connected by means of a pipe or hose connection, it can be equipped with a device according to FIG. 8, which serves as a check valve 56 and baffle plate as well as the quantity regulation. The nozzle can also have a jet shaping device, a steering jet insert is also conceivable, it being possible for these additional devices to be interchangeable.

Fig. Lo shows the configuration of a nozzle combination, which is both adjustable and lockable, as well as directionally adjustable, preferably carries a self-check valve 56 and / or can be switched off manually. In addition, the exchange of the nozzle insert for different jet shapes is conceivable. The air duct extends into the air duct 4. _to guide nozzle 11, coaxial to the air supply nozzle, a support flange 9 is inserted in the basin wall 1, which carries an axially adjustable ring lo with a conical inner bore, which together with the air supply nozzle 11 forms an annular channel 29, the free cross section of which is adjusted by adjusting the ring lo can change. The adjustment of the ring 10 is preferably carried out from the inner basin, wherein for example the steering jet nozzle 22 engages in bores 24 by means of pins 41 under pressure against the spring 25. It is not only possible to regulate the quantity but also to shut off the supply of a medium. For this purpose, the ring lo only has to be screwed in until it abuts a stop 64. The beam is deflected by an exchangeable steering jet nozzle 22, which preferably has a spherical surface. The steering jet nozzle, which also serves to shape the jet, is preferably held by a screw ring 12. The compression spring 25 preferably serves as the counterbearing for the steering jet nozzle. In addition to the above-described regulating and shut-off option, the nozzle construction can additionally have a check valve, preferably as shown in FIG. 8, which also serves as a baffle plate 56 and closes the nozzle outlet when the pump pressure is switched off, which is advantageous Installation of the check valve 56 directly in the steering jet nozzle 22. In addition, however, it is also conceivable to design the ring lo as an automatic check valve, whereby the restoring force of the spring 25 can be used or the restoring force of the bath water flowing back. To form a check valve, the ring 10 need only be freely supported; when it is reset, it seals against the stop 64. A check valve can of course also be installed in the form of a check ball, a flap or in the form of a lip seal.

11 shows a further variant of a steering jet nozzle, the nozzle 13 now being used for jet deflection itself. The support flange 9 has an internal thread 19 and assumes a cylindrical nozzle portion 18 with external thread 19 A in which _D Usenteil 18 of the one part has a coaxial bore of a nozzle 13 and on the other hand an eccentric bore 2 _0, which is used for beam deflection and the Strahlausformung. The nozzle part 18 is exchangeable. However, it is also conceivable to resiliently mount the nozzle part 18, the supply lines opening automatically when the pump pressure is switched on and closing the supply line when the pump pressure is switched off. The beam deflection and quantity regulation are carried out from the inner pool by turning the nozzle part 18.

The expansion in turn causes a change in the flow conditions in the annular channel 29 between the air supply nozzle 11 and the nozzle 13. The nozzle part 18 can of course be screwed into the carrier flange 9 until a shut-off of the water inflow is effected. In this embodiment, too, a check valve 56 can be installed as described above (FIG. 8).

It is also possible to install a different check valve configuration.

FIG. 12 shows a carrier flange 9 with an internal thread 19, over which an axially adjustable nozzle carrier 14 is guided and through which the nozzle 13 is held in a quantity-adjustable and jet-deflectable manner. The nozzle 13 is designed with a spherical surface 23 and is pivotably mounted in the nozzle carrier. By rotating the nozzle carrier 14, the nozzle 13 is moved axially against the air supply nozzle 11, which in turn causes a cross-sectional change in the annular channel 29. The nozzle carrier 14 can be screwed into the carrier flange 9 until the inlet on the back of the nozzle is interrupted. Of course, it is also possible with this construction to design the shut-off for both water and air using a check valve or a seal. According to the invention, it is proposed to design the nozzle 13 by means of a sealing ring which opens at pump pressure and seals between the nozzle 13 and the air supply pipe 11 when the pump pressure is switched off. Spring force can be used for resetting. The use of a spring-loaded baffle plate 56 (FIG. 8) with a check valve is also conceivable. The tangential water supply on the back of the carrier flange 9 is advantageous. The massage jet is twisted by tangential water supply. This embodiment of a nozzle construction according to the invention also enables det. Replacement of the beam shaping device.

FIG. 13 shows a further variant of the nozzle 13 which is used for beam deflection, quantity regulation and beam shaping.

The nozzle unit 13 is exchangeable; it can be guided in a carrier flange or inserted directly into the basin wall 1. The nozzle 13 is guided via a screw thread in a partial ball 15. Instead of the thread, a pressure-adjustable nozzle part can of course also be used, which is preferably sealed by an O-ring. The free cross-section in the annular channel 29 is changed by rotating or moving the elongated nozzle of the nozzle 13, which also serves as a deflection nozzle, if the air supply nozzle 11 is used. The nozzle is preferably attached as described in FIG. 10. It is proposed according to the invention to form the narrowest cross section of the nozzle 13 through 62 a sealing ring 76 and to press it against the air supply nozzle 11 by means of a compression spring. This device, which acts as a check valve, is opened by pump pressure. The installation of a baffle plate 56 (FIG. 8), which also acts as a check valve, and another configuration as a check valve is also conceivable.

FIG. 14 shows a variant of the nozzle 13, which enables a fan-like beam configuration, can be mounted rigidly or adjustable in direction and can also be exchanged. The water outlet can be designed to be adjustable by axial change. According to the invention it is proposed to equip the nozzle 13 with a slot-like outlet 16, the slot-like outlet 16 being attached to a ball 13, but it is also conceivable to equip both the nozzle in FIG. 13 and the one shown in FIG. 14 with a disk 17 instead of a spherical surface 15, with which the nozzle 13 is held and guided. The disc 17 can be held and pivoted in a hollow spherical bearing. Preferably, the disc 17 carries an O-ring seal on its outer circumference. A check valve can also be used with this nozzle construction as described above.

FIG. 15 shows an embodiment of a nozzle variant 13 according to the invention, which is formed by a rotor 21 which is mounted on the air supply nozzle 11 and is used for circular jet shaping. The carrier flange 9 is designed as a holder, as in the previous variants. The rotor 21 is preferably held on the end face by the discharge guide 44. The outlet valve can have interruptions 45 at the provided locations, which interrupts and pulsates the emerging water and / or air jet. It is also possible to mount the rotor 21 radially or to feed the driving medium axially or radially to the nozzle combination. The rotor can be exchanged for another jet shaping device, of course the rotor itself can serve as a check valve and effect sealing between the nozzle 13 and the air supply nozzle 11, a check valve 56 according to FIG. 8 is also conceivable, as is a check ball, clap device or lip seal. By rotating the outlet link 44, the rotor 21 can be moved in the axial direction, which causes a change in the annular channel 29 and provides the possibility of regulating the quantity.

16 shows a distributor 6o and shut-off device according to the invention, which is used in particular for nozzle constructions with an axial water outlet and radial or coaxial air guidance. The distributor 60 also serves as a check valve, which preferably blocks the water outlet and the air outlet at the same time. A compression spring 62 can serve to reset the valve, but the reset can also be effected by the reflux water. Of course, the reset can also be done manually. The distributor 60 is preferably also used to regulate the jet and to shut off the outlet nozzle 11 and / or 13. In the refinement, it is proposed that the distributor 60 be adjustable against the water outlet 63 by means of a screw thread with an adjustment option 65. The distributor 60 can be fastened both within the nozzle carrier 9 and on one of the nozzles 11 or 13. In its further development, the distributor 60 is designed according to the invention as a diffuser 61, preferably equipped with a sieve-like device with a large number of small openings (pores) 61 which produce a large number of venturi effects. The distributor 6o with diffuser 61 can also be mounted rigidly (without resetting), it can of course also be used in nozzle constructions with axial air and coaxial water flow, this device according to the invention can also be installed in any type of beam deflection device.

The Fir. 17 shows a variant of a nozzle according to the invention, which in a preferred exemplary embodiment has a connection part 57 on the back of the water basin, which is connected to the nozzle carrier 9 and, like a screw closure, clamps the basin wall 1 in a sealing manner. The connecting part 57 is designed with at least one connection for the air supply 58 and at least one connection for the water supply 59. The connections 58 and 59 lie one inside the other, they are designed for connecting a pipe-in pipe system. The pipe-in pipe connections can be designed on one side as well as on several sides in the manner of a distribution on the connection part 57. On the inside, the connection part 57 carries axially to the nozzle carrier 9 a nozzle 11 through which water or air can be supplied. The second medium that is not introduced through the nozzle 11 is introduced radially or coaxially. The inner tube 58 can preferably be led out at the rear end of the connecting piece 67 (broken line).

The connecting part 57 shows a further nozzle 66 through which, depending on the guidance of the media water or air, the other medium is additionally introduced into the inner tube 58, which results in a coaxial superimposition of the two media, air and water, in a number of ways. Of course, a blower can also be connected to the connection 67.

In the further development, the outlet nozzle 11 can be provided with a distributor device (diffuser) 60 with openings 61. The nozzle 13 can also carry such a device. Of course, a check valve can also be installed with this nozzle combination, steering jet and jet shaping devices of various types can also be used.

Of course, the advantageous embodiments of nozzles, check valves, distributors and diffusers, beam spray devices, jet shaping devices, pipe-in pipe systems described above according to the invention can also be used in water basins of the known type, in particular are used in nozzle designs of known type. Also in channels.

18 shows a nozzle variant according to the invention, which is used in particular for the irradiation of air, the irradiation taking place largely parallel to the water basin wall or water basin floor surface. This construction, which is particularly suitable for the pool floor, enables a star-shaped radiation with a large distribution. Of course, water or a water / air mixture can also be blasted through this nozzle. Of course, this can also be equipped with details of the nozzles described above, it can be used in a duct system or in a pipe connection system. In the pool wall 1, the nozzle holder 9 is inserted, which preferably carries a ball check valve 74. A flap check valve is also conceivable. At least one outlet opening 69 is provided parallel or approximately parallel to the basin wall 1, through which the respective medium can exit into the basin interior 6. In addition Of course, at least one axially acting outlet opening 7o can also be provided. The nozzle holder 9 preferably holds a removable cover ₇₅ which can have rotatable lateral interruptions which serve for the discharge of at least one medium and which can preferably be opened and closed or regulated by a rotary movement. The nozzle holder can of course also be connected via hose lines 26, via which the connection to a pressure generator is made. This nozzle construction, with star-shaped or simple radiation, is particularly suitable for insert pools 38, whereby thin hose lines between old pools 39 and the insert pool to the inlet openings 7 for water and / or air can preferably be used.

The medium outlet openings 69, 7o in a star-shaped arrangement enable rotation of the check ball 74 which, in rotation, conceals the outlet openings in the housing and thus causes a pulsation of the medium.

However, it is also possible according to the invention to arrange a rotor below the cover 75 which, driven by a medium (air or water or a mixture), radially deflects the medium towards the outlet openings and helically swirls through lateral interruptions in the outlet. 19 shows a further variant of a nozzle construction according to the invention, which is also suitable for both water, air or mixture radiation. It can be used in a duct system, it can also pipelines t _un gen or hoses are connected. The nozzle holder 9 is clamped in the pool wall 1. A lid valve 72, as is known in shape, for example, as a plug valve, is mounted in the circumferential outlet opening 71 of the _D üsenträgers. 9 The outlet openings can also be formed from a large number of bores, as is known in terms of shape, for example in gas burners. In the idle state, the cover valve 72 preferably sits in the seat 73 at approximately the same height as the installation level 1. When the pressure is applied, the cover valve 72 is lifted out of the seat 73 and the outlet path for the medium is cleared. When the pressure in the medium decreases, the cover valve 72 is returned to its seat by the pressure of the pool water, it preferably serves as a check valve, but a ball check valve 74 may also be present. In addition to the water pressure in the pool, dead weight or spring force can of course also be used for the reset. The cover valve 72 is exchangeably mounted in the carrier flange 9, the medium outlet can circulate around the cover valve without interruption, but the medium outlet can also have interruptions, which leads to a radiation-shaped or star-shaped beam configuration. The cover valve can also have at least one axially acting medium outlet opening 7o. According to the invention and preferably it is proposed to design the lateral outlet 71 in such a way that lateral bores deflect radially-tangentially and cause the cover valve 72 to rotate. It is also proposed to combine the nozzle according to the exemplary embodiment 9 with radial openings 43 with the nozzle according to this exemplary embodiment by introducing the radial openings with a direct pool water inlet in the flow direction of the outlet medium (air) into the housing under the cover valve 72.
