Günter Schüasie'r ^ 8οδο Mtiflohen ¹ "' _p4 * Water basin with air bubble device
State of the art

The invention is based on a water basin with an air bubble device according to the preamble of the main claim. Such pools with an air bubbling device used for massage purposes, under water ^one basin a hand or foot basin, a bathtub, as well as a hot tub or a larger pool Got it is. 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. In this way, on the one hand, the water in the water basin is moved and revitalized and, on the other hand, the body parts exposed to this jet are massaged.

In these generic water basins known in many ways Using an air jet device, the water is sucked out of the inside of the pool by a pump and then fed back into the pool via the water nozzle to generate a jet Inside the pelvis introduced. In principle, the air is carried along with the water jet pump or blown into the interior of the pool by a fan.

In order to supply air and water to the individual nozzles, the water basins I extensive cable routing required, which takes up a considerable amount of space require. Since air and water nozzles are usually assembled into a unit, connection 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 creates a considerable risk of constant leaks. In many In some cases, after the installation of the water basin, the connection points of the nozzles are no longer accessible from outside the basin, so that leaks may only occur can be remedied by expanding the entire basin.

In a known water basin of this type (US-PS 4233694) the nozzle Inserted on the inside of the basin and clamped to the basin on the outside, the nozzle-receiving hole 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 connected to a pipe running around the pool. As in this example of a known water basin, such a line routing and nozzle installation disadvantageously requires a considerable amount of effort Assembly time, not to mention the cost of the large number of small assembly parts. Each of the individual sealing points brings the risk of leakage, which is promoted by the constant temperature changes in such water basins will. These known systems have the disadvantage that, due to the required structural volume, the lines have the smallest possible cross-section

· A

have, which on the one hand result in high flow losses and on the other hand the elasticity of the system is low. That through the pipe installation flowing water cools down quickly and has to be reheated before it can flow back into the interior of the pool.

In a known nozzle design (U.S. 3,336,921 and U.S. 2,738,787 uses its own nozzle housing, which is attached directly to a pump unit is. The known nozzle designs all have the disadvantage that this either can be integrated into a pipe system in complex detailed work or connected to an unwieldy pump unit, which of course means the movement freedom of access is a hindrance. Another disadvantage is that known Nozzle constructions do not have a self-closing check valve and when using a foam bath, undesirable soap residues can penetrate into the pipe or sewer system, which leads to undesirable effects. A Another disadvantage is that nozzles of the known type have a round, punctiform Generate a massage jet, which of course does not have a surface effect, the water jet shaping device cannot be exchanged, for example, for a fan-shaped, rotating, star-shaped jet, etc. Last but not least, known nozzle designs cannot be used in a channel system, they are expansive, cannot be locked and cannot be used in a water basin serving as indoor use, such as those used for the renovation of existing old basins. The multitude of disadvantages well known Nozzle and tub designs emerge in particular from (U.S. 3.297.o25).

Advantages of the invention:
The water basin according to the invention with the characteristic feature of the main

2.5 claim, in which the channels are designed like cavities running in the pool wall, has the advantage that there are almost no sealing problems and the connection point can optionally be placed individually in such an area that is easily accessible for inspection purposes. If necessary, the nozzles are advantageously inserted from the inside of the basin and only those connections are required to the outside that connect the water or air pressure generator, for example a pump or a water supply system, to these integrated channels. The water and / or air outlet openings can be produced in a simple manner after drilling through the pool wall. In the simplest embodiment, the bore may i _n the tank wall itself serve as the outlet nozzle. Further nozzle designs can be inserted directly into the channels through the hole in the basin wall. A separate nozzle body or nozzle housing is not required in this simplest embodiment.

The channels can be flat and due to the available

^ ^ _{# lit}

the wide basin wall can be chosen to be correspondingly wide, so that a large passage cross-section is given in spite of the small volume application i: t. In the case of water basins made of plastic, for example acrylic glass or GRP (glass fiber reinforced plastic), the channels can be obtained in that the not dur; ¹ } the channel wall formed by the pool wall can be obtained by laminating half-shells onto the pool wall. Of course, it is also conceivable to work the channels directly into the existing plastic using a manufacturing process. In the case of cast basins, these channels can also be cast in, for example in the manner of a melt-out process, as is customary today in cast boiler construction. at

J.0 CLEANING OF THE STALLJ.

It Ji can be welded onto the outer wall of the pool wall. of course is it is also conceivable to gain the channels by placing such, the ducts delimiting and covering delimitation parts, which can also accommodate the nozzles, are placed. This will make the The tightness requirements are significantly reduced. Of course, an embodiment according to the invention is also conceivable in which the channels are only provided by one double-walled formation of the whole basin would be formed. Stiffening webs between the walls would create channel boundaries. The nozzles could can be used at almost any point in the pool wall.

There is an additional advantage of the channel and nozzle design according to the invention in that the inner surface of the channel is relatively easy to resist corrosion can be protected by simply passing coating agent through the channels, which can be deposited on the channel surface. Particularly The production of the channels is advantageous if for this purpose, according to the invention, a casting compound, preferably waxy, is used. The later canals are modeled on the pelvic body, with the modeling and enamel mass corresponds to the later channel cross-section. In this way, molds and half-shells for channel production can be manufactured very easily. It is also rnL ^ - lent to coat the applied modeling clay. In making the Channels made of plastics is proposed according to the invention, which are used during the curing process to use the heat generated by the plastics to melt out the modeling clay, or at least to initiate the melt out in this way. The advantages of this method according to the invention are in particular in that a channel or cavity coating can be done very easily by, for example, the modeling compound applied in strips to the pool wall a coating is applied, which appears as the channel surface on the inside of the channel after the melting process.

It is conceivable that the cavities and channels made of thermoplastics to manufacture and e.g. form-fit prefabricated acrylic glass or PVC parts

Use ductwork, with an additional overlaying with GRP increases durability and tightness. Pipes or pipe parts of various shapes can also be used for sewer production. In a further method which can be used in the production of metal pools, it is proposed that the channels preferably likewise Manufactured in the melt-out process, whereby the channel walls are made by applying epoxy resin with additives. Such mixtures, Commonly known as "cold metals", they can be applied by spray, brush, cast or roll-on processes, as well as putty.

Instead of the melting process, a combination can also be selected, where e.g. prefabricated pipes or half-shells are used instead of the molten mass and these are not only glued on, but attached to the pool by means of a coating, preferably a cold metal coating or GRP coating will. Of course, a screw connection is also possible. Of course, heating rods can also be inserted into the melted-out mass after the melted-out be removed again.

The embodiment of the invention has channels accessible from the inner pool the advantage that by removing the manhole cover towards the interior of the water basin, no external seals have to be loosened. By removing the Manhole cover, the nozzles on the back are accessible, channels and nozzles can can be easily cleaned or replaced if necessary.

According to embodiments of the invention, the water channel can be inside the air channel or the air channel can be arranged within the water channel or they can run next to one another, with only one web between the channel cover part and the basin wall is required to separate the channels. Of course, the channels according to the invention with pipes of the known type be combined in that, for example, the water-carrying channel is formed by a cavity in the stretching wall and the air-carrying channel via a Hose or pipe that is guided inside or outside a cavity or vice versa.

It is particularly advantageous if the channel (s) under the water basin floor is / are performed and nozzles are provided accordingly on the bottom side of the water basin. The invention enables "nozzles, which over the inner surface of the Do not go outside the pelvic wall, be careful? ·. ■. '. ■ /; In some cases only through a hole in the Pool wall formed so that the bathing guest does not have any protruding from the wall Interfere with the nozzle body on the bottom or the wall of the water basin. According to the invention, an air-water mixture is supplied to the pool floor a very intense massage effect without the need for an additional fan is required.

The embodiment of the invention with the features according to claim 6 has the advantage that such ventilation can be directed to the top of the pool. Depending on the design of the water basin according to the invention, the air can be used to Air bubbles are sucked in there. The air duct is preferably so | created that when using a fan this is not flooded. Before- , the air duct is preferably arranged spatially above the water duct so that it is easier to ventilate. The ventilation can also be via a regulating valve take place so that the amount of intake air is controllable. Enable automatic valves the individual commissioning and control of individual ·· "nozzles. § The installation of at least one check valve is proposed so that bathing g water cannot enter the ventilation duct, preferably everyone is jij each nozzle is assigned a check valve, which is provided directly on the nozzle and that is, for example, opened or closed as a ball check valve or a check valve by pressure or negative pressure in the ventilation line is closed. The pressure or negative pressure can be generated by a Circulation pump or a fan, which are also used to convey one of the media (air or water).

Valves controlled by additional external energy, preferably solenoid valves can be used to control individual nozzles or groups of nozzles, for example to achieve an interval-like massage effect.

The channels and cavities in the pelvic walls, as well as on the pelvic floor, can be arranged so that it can be used to transport a water-air mixture. ™ are. This advantageous embodiment makes it possible, for example, to arrange the air supply at an easily accessible point from which a distribution to different inlet points can also proceed.

Understandably, the channels or channel parts can be prefabricated and equipped with facilities which correspond to the intended use. Such prefabricated parts, for example with connecting pieces jsw. can then simply placed on the pool wall and fastened.

Of course, it is possible to use the water basin according to the invention with air and to design water channels in such a way that once only air and once only water gets into the inner basin or that a water-air mixture inside of the channels or within the nozzles and this is fed to the inner basin. Those used for the purpose of supplying water and / or air Channels are preferably arranged so that they are after using the water basin Empty the residual water independently.

The features of the claim which can be combined in particular with features 1 to 2o 2 have the advantage that special insert tubs for every type of old tub can be designed. Due to the small spatial extent of the

Channels according to the invention can cause little loss of space in any existing old pool an inventive water basin can be installed as an insert. So can E.g. in the further development of the insert basin, advantageous indentations, such as are desirable for the armrest and for saving water volume are used to accommodate the channels. The channels can be on the back of the liner pool also be embedded in height-compensating P.U. foam or other filling compound. In this way, bathtubs can be built with little loss of space and little effort without dismantling the same, can be converted into a "whirlpool", with either only air or only water or an air-water mixture for the production of bubbles is being used. In order to allow the installation of an inventive one even with relatively small old tubs To enable water basin, it is proposed that bottom parts and / or wall parts of the old basin preferably cut out in such places that the water and / or air channels or supply lines within the cut out Places come to rest and only the remaining walls of the old tub are used to statically secure the basin. Is particularly advantageous it to provide the insert basin according to the feature of claim basin inside with a connection piece through which, for example, compressed air in the duct system can be blown in. This design has the particular advantage that an easily accessible blower generating compressed air is nearby the water basin can be attached without affecting the often too narrow space Consideration must be given under the water basin. A particularly effective massage effect is used in the water basin according to the invention, however, also in pools of the known type, generated when the water and / or air jet is pulsed, it is also proposed according to the invention, the circulating water to several nozzle sections, for example right, left, and these sections alternately at intervals with circulating water or To charge air.

According to the invention it is proposed that in whirlpools which are equipped with a filter and water treatment system are equipped, the ducts or pipes to To use the return of the filtered water in the inner basin and in the water return channels Use nozzle combinations that jet the water into the area of the pool floor or its edge area. Through repatriation In the area of the pool floor there is better water circulation in the indoor pool given the air supplied causes a special revitalization of the water and penetrates the entire pool water when buoyant. The arrangement of Combinations of eyes (air and water) in or at least close to the floor area the water basin has the advantage that an additional fan for generating a floor air bubble is not required. According to the invention it is therefore proposed also equip water basins of the known type with water-air nozzles, which irradiate in the pelvic-Bodert area.

In the further embodiment of the channels, it is proposed according to the invention to connect the water-carrying channel to the air-carrying channel in such a way that either air can get into the water channel or water can get into the air channel. The transition point at which one medium is transferred to the other medium is preferably designed as a nozzle from which the transferred medium can exit. The transferred medium can be transferred to the other medium either under pressure or by negative pressure. The transition point of one medium, designed as an outlet nozzle, acts in the further development with a second outlet nozzle, the effective cross-section of which causes a change in the flow rate of the second medium and operates on the principle of the water jet pump. Both the Bernoulli effect and the Venturi principle can be used / grounded. In the simplest embodiment, the water basin wall itself is preferably used as a nozzle for the second medium, it is only important that the transition point formed as an outlet nozzle for the first medium acts in such a way that the medium with the lower flow velocity is separated from the medium with the higher velocity gets carried away. For this purpose, the outlet opening of the first medium can preferably protrude into the outlet nozzle of the second medium to such an extent that a cross-sectional constriction arises there, which causes the required flow velocity. Such constructions are known as water jet pumps and therefore do not need to be explained in more detail.
Another embodiment of the water basin according to the invention proposes that the water and / or air outlet opening introduced as a bore in the basin wall preferably be equipped with a thread through which a ring acting as a nozzle can be screwed in and out. The ring has an inner bore, preferably conical in shape, which acts as a nozzle. By changing this nozzle ring in the axial direction, an effective change in cross section of the free cross section between the outlet nozzle for the first medium and the outlet nozzle for the second medium is brought about. The change in cross-section enables the flow rate to be regulated, on the one hand, and the mode of operation of the two nozzles, on the other hand, in that larger quantities of the first medium are transferred and entrained at a higher flow rate of the second medium. In the further development, the nozzle ring can be designed in such a way that it can be operated and adjusted from the inner basin, so that the outlet nozzle can be regulated and its output can be individually adjusted and / or closed. The outlet nozzle of the first medium can also be designed to be adjustable. Regulation and / or blocking can also take place at the rear end of the nozzle by narrowing the cross-section.

According to the embodiment according to the features of claims 7 to 2o, which are both an advantageous embodiment of the invention as well as an invention claimed in itself, such a nozzle combination can be adjustable, for example by axially or radially acting rotation or displacement _s whereby the regulating possibility can extend to the outlet of water without air admixture, up to the maximum air admixture and beyond that up to the blocking of the water and / or air outlet.

It is also proposed to make the water and / or air outlet opening pivotable and directionally adjustable towards the inside of the pool, whereby it is particularly Another advantage is that the outlet nozzle can be adjusted both in terms of quantity and direction and to make it lockable, whereby the lock can be made manually or is effected by an automatic check valve. The embodiment of the invention with the features of claim 7 has the advantage that nozzle inserts are used for different beam formation, which are interchangeable depending on the desired mode of operation. on The reason for the independent attachment of the inner nozzle is a multifaceted configuration the water-air nozzle combination possible. Depending on requirements, the nozzle combination that works according to the water jet pump principle can use the other Medium entraining pressure jet can be fed axially or radially. As a fellow traveler Pressure jet can serve either water or air, so that e.g. Water is supplied under pressure axially or radially and air is entrained in sufficient quantities the air duct only needs to be open to the outside (ventilated). The supply of water and / or air can of course within the ca | ' sewers also run the other way round, with the same or a different nozzle design.

In a further embodiment of the water basin it is proposed that one under To mix in a pressurized air jet of water from the inside of the pool, the admixture taking place through radial openings in the nozzle wall, through which the amount of air flowing in under pressure sucks in and entrains parts of the water. In addition to the well-known point-like mode of action of a massage nozzle, there is also a surface effect to produce is proposed according to the features of claim 8; To design nozzles with slot-like water and air outlet, the outlet f Slot should preferably be rotatable by at least 9o, so that the fan-like jet formed by the outlet slot, seen from above, is once in ner width and after turning the nozzle by 9o can be seen in its narrow side.

In addition, it is advantageous to design a beam deflection that is adjustable in the direction, even with a fan-like beam shape, whereby outlet nozzle designs known per se with a spherical surface can be used. According to the invention, it is proposed that the outlet nozzle, preferably exchangeable , be designed to be adjustable in terms of both quantity and direction and in a holder

to lead, which serves as a nozzle carrier and is exchangeable. According to the features of claim it is proposed that rotating nozzles are also used Art to design, which is a steadily moving, preferably circular drawing Shape the beam. The centrically guided outlet nozzle of the one medium can advantageously be used as an axle bearing for a rotating nozzle part be used. The rotating nozzle part is driven by the pressure medium and shapes the moving beam.

The interchangeability of different nozzle parts has the advantage that with few Handles Nozzles with round, fan-like, circular, star-shaped | etc. Beam shaping can be used so that the bather is individual Eil can choose between punctual or surface massage. The exchangeability of nozzle designs can of course also be used in water basins of the known type or used in combination wherever in a water basin according to the invention with channel designs additionally still nozzles the known type can be grown from the outside of the water basin. According to the invention it is therefore proposed to design the nozzles in such a way that they can be used in a channel system according to the invention, and that a pipe connection of the known type can be used. As special It has been shown to be advantageous if, according to the invention, a combination of pipe and sewer system is selected, e.g. in one of the water conduits serving channel an inserted air pipe is used. When using several Single jet nozzles can be connected to each other in this way, all the advantages described above are retained. According to the invention it is proposed in the further development, a larger tube on the outside of the basin To use diameter to guide one of the media, a tube of smaller diameter is laid in its cavity, which is the guide of the other Medium serves. In this way, both media (air and water) are practically guided in a single pipe. This pipe combination can go from nozzle to nozzle be relocated. The connection between the pipe and the pool wall is made in a known manner Way.

In the further development of the nozzle combination, it is proposed to provide the air outlet opening with a diffuser which divides the supplied amount of air into a large number of small partial air flows. This device can be used both in the water basin according to the invention and in water basins or nozzle constructions of a known type. This device has the advantage that a large number of tiny air bubbles are added to the water jet instead of large air parts ₃ which naturally, contrary to their buoyancy tendency in the water, are introduced as small parts by the water jet far deeper into the pool interior than is the case with large air bubbles |

If so, a fine sieve or a pore-like device can preferably be used as the diffuser. A multitude of pores, from which air particles are torn out, result in a multitude of venturi openings with a fine distribution of the water-air mixture. Of course, another device can also be selected for this fine distribution (diffuser ^a fine distributor) of the air supply.

The design of the nozzles with one or more backflow preventer can are preferably carried out with one or more lip seals, which open after switching on the pump, preferably such seals can be inside the Wasseraus form nozzle or sit between the nozzle and channel or water supply. Ball or flap valves can also be used. The air supply nozzle can also be equipped with a check valve: be, which preferably opens at negative pressure, or is closed by bath water reflux. The pump pressure can also be used to open the check valve can be used in the air duct.

In the case of an axial water supply to the nozzle, it is proposed according to the invention that also to design a non-return valve, which opens when water is supplied under pressure and preferably closes again as soon as a counter spring is pressed the pump pressure drops. The design of such a check valve also has the advantage, for example, that the amount of fluid emerging from the nozzle The amount of water can be regulated. The check valve preferably has the shape of a baffle cone, through which the water-air mixing is essential is favored. Of course, there is also a rubber lip valve with axial water supply or a ball or flap valve is conceivable.

The feature claimed in claim is also, on the one hand, an advantageous one Embodiment of the invention, but on the other hand a claimed invention which can also be used in water basins of the known type. Of the The advantage of keeping germs free in cavities, channels, pipelines, etc. is of of essential importance, especially if there is residual water after use of the water basin in the pipes etc. remain. According to the invention it is proposed to add an additive point to the pool water circulation system to be assigned and to train them in such a way that appropriate disinfectants can be added. The addition point is preferably at the upper edge of the pool arranged and formed an easily accessible filling device.

It is advantageous to design a standpipe ₃ through which the water circulation does not flow and only allows additives to enter the circulation system when the water basin is emptied.

In addition to the nozzle designs described above for air and / or water Nozzle constructions can also be used in the water basin according to the invention which only serve to supply air.

According to the invention, the air irradiation is proposed for the purpose of creating air bubbles, to choose radially deflected. This has the particular advantage that nozzles can be designed with several outlets, which are also easy can be closed by a check valve and regulated if necessary. Such a nozzle formation can be designed, for example, like an egg Nozzle head of a gas burner with a plurality of outlet openings, the Outlets preferably by turning the outlet openings manually or against Blower pressure can be closed. Such can be particularly advantageous Air outlet nozzles used in the pelvic floor area or on pelvic benches but especially where an increased massage performance is desired, especially in the back and lumbar area of the bather. Opposite to Individual nozzle bores with only a small air passage, the proposed nozzle construction therefore has an increased massage performance, because, so to speak, themselves there is increased turbulence in the vicinity of the nozzle with multiple openings.

It is advantageous to have the air radiation in a star shape, approximately parallel to it irradiate the flat surfaces of the water basin in order to widen the effectiveness of the nozzle to a larger area.

In a further embodiment, it is proposed to design the air jet nozzle with a non-return cover, which lifts out of its seat when the fan is switched on and reveals a circumferential cross-section from which the compressed air can escape. This embodiment has the particular advantage that when the fan is switched off, the nozzle has almost no increase in the planes of the The water basin is seated and only protrudes a few millimeters into the water basin when the blower pressure is applied. When the blower is switched off, it prevents it again closed lids prevent bath water from entering the sewer or pipe system.

Description of the exemplary embodiments:

In the water basin shown in cross-section and longitudinal section in FIGS. 1 and 2, which can be a whirlpool, a channel system with cavities for water 3 and air 4 is formed by the basin wall 1 and the delimitation part 2 connected to it from the outside. The cavities 5 used for water flow are supplied with pressurized water via a central line 5 from a pump (not shown) or from a water supply network, in the former case the pump takes the water from the interior 6 of the water basin or from a surge water tank (not shown) . The cavities 3 used to guide the water can also consist of several sections, each section being able to be assigned its own inlet connection. From the cavities 3, the pressurized water is radiated into the inner pool via the nozzle bore 13, which is arranged below the water level of the interior 6 in the pool wall 1. The nozzle 13 can be formed by a simple bore in the basin wall 1, it can be developed in many ways, for example as a tube 9 which protrudes into the channel 3, it can be designed as a decorative flange on the inside of the basin. The tube 9 can be attached both to the pool wall 1 and, for example, by a device within the channel 3. The nozzle 13 can be formed by a ring Io which can be adjusted axially within the bore in the basin wall for the purpose of regulation; such a ring, which preferably has a conical bore, can also be received in the tube 9, the nozzle 13 can be mounted adjustable in direction, it can be held and guided by a carrier, which can serve both an adjustment in the axial direction, as well as for the purpose of jet deflection and for the purpose of inflow water shut-off and the purpose of nozzle exchange. Given the large number of design options for the nozzle 13, the different variants always have the common feature that the rear end 13 A protrudes into a channel 3 or 4. The nozzle 11, which carries the second medium, is coaxial with the nozzle 13 and is preferably an air nozzle d ·· ⁻¹ · into the channel 3 filled with water. The air supply nozzle 11 cooperates with the nozzle 13 in the manner of a water jet pump.

-13-

In Fig. 1, two variants of an embodiment are shown side by side. In the variant shown on the right, the air supply nozzle 11 is in its extended configuration via a hose 26 with the supply air valve 27 connected, which is inserted into the upper edge of the water basin 28. This air intake valve 27 can be designed as a regulating valve so as to in the simplest way to throttle the sucked air more or less or to interrupt the air supply. A can of course also be connected to the supply line 26 Fan are connected, which the nozzle 11 supplies compressed air. The regulating valve 27 can also be designed as a check valve or a solenoid valve. In the left half of Fig. 1, a variant is shown in which the

Boundary part 2 has a water-bearing cavity 3 and an air-bearing one Cavity 4 covers. The two channels 3 and 4 are only separated by a web 3o, which of course can also be formed by the basin wall 1. The delimitation part 2 is connected to the basin wall 1 by the web 3o. As in the first variant, the nozzle 13 is shown as a hole in the basin wall 1 and the extension attached to the delimitation part 2 protrudes of the air supply nozzle 11 coaxially into the bore used as nozzle 13 in the basin wall 1 into it. In contrast to this variant, however, the air supply nozzle 11 is extended by a connecting part 31 and with the connected air-conducting cavity 4, which has an air intake valve 27, that is present in the upper edge of the pool. Basically, this variant works like the other, with the extension of the air supply nozzle 11 on the Web 3o penetrates the duct wall and leads into the cavity 4, while in the other variant the extension of the air supply nozzle 11 on the boundary wall 2 penetrates the duct wall and is continued through the hose 26. Of course, instead of the hose, a channel or find a pipe use.

In Fig. 1 is another line below the water basin? ⁰ indicated, which should give an indication of a further variant of the air and water flow. The air supply can namely also via an air pressure generating device bubble are caused and then introduced from this central point 32 of the air supply nozzle 11 or into the cavity 4. This means that significantly larger amounts of air can be injected into the water basin than is possible with the water jet pump principle. Of course, it is also conceivable that air blown in under pressure is used as the pump medium and water is entrained, namely according to the Vetituri principle, as is used, for example, in liquid atomization.

In the water basin shown in vertical longitudinal section in FIG. 2 The cavities 3 and 4 of the second variant can be seen in the X-ray image. The two Cavities, of which the lower one is filled with knowledge, are through the web

3o separated; the upper cavity 4 is ventilated via the valve 27. Instead of this an open ventilation or a check valve can also be provided. In Fig. 3, a further variant of the assignment of the cavities 3 and 4 is shown with a correspondingly differently designed nozzle combination. In this j 5 variant there is one between the channel delimitation part 2 and the basin wall 1 Partition 34 out. The specially designed nozzle body 35 penetrates

Basin wall 1 and partition wall 34. In the area of the cavity it has 4 radii

\ dial openings 36 through which, according to the Bernoulli principle, air is drawn in and

is entrained or through which air is supplied under pressure. The water In this nozzle body 35, Io is axially out of the cavity 3 via an in the nozzle body provided constriction 49 out, which shapes the beam. Also a reverse Air and water guidance is possible so that water is injected via the radial openings, which can also be ring-like openings

... is radiated into the indoor pool with the entrainment of air. Through this facility the injected water receives a twist. A flow rate regulation of the type already described is also possible in this variant.

■ In Fig. 4, a further variant of the duct system according to the invention is shown

represents, in which the basin wall 1 is the outer boundary wall of the cavity 3 forms. A removable plate 37 in FIG which the water \ ind / or air outlet opening 7 is arranged. Also others Components of the nozzle combination can be included there. The plate itself can also be a support flange for one or more nozzles. Also at In this embodiment, 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. 4, can also be provided on the bottom.

It is also conceivable that this cavity, instead of the water duct, the air duct serves and that the water is supplied via pipes or that two channels run side by side, individually or jointly through corresponding Covers to the inside of the water basin are covered.

In Fig. 5 and 6 a second embodiment is also in cross section and shown in vertical longitudinal section, in which an inventive Water basin 38 serves as an insert for an immobile old basin 39. This type of modernization is typical for bathtubs in which the old basin is being expanded is too expensive and the insert basin 38 is only used in the old basin 39 must become. The connections for air and / or water can be through the Old basins existing openings or through additional holes made can be reached. In the case of relatively small old pools, openings can be cut out in which the channels 3 and / or 4 run. Of course, the old pool can also have holes or cutouts in several places which several connecting pieces are brought up to the insert basin 38,

39 can through cut holes and openings in an old basin any type of supply lines under the space of the old tub can be brought up to the insert basin 38, the supply of air or the supply of Water and air. The insert basin 38 is at least in partial areas! the side walls are statically supported by the cut-out old basin 39 and held. Air supply nozzles can be used in the insert basin, Water supply nozzles and combined water and air nozzles. The nozzles can be used individually be connected, for example, via hose or pipelines or in a canal or pipe system that at least partially surrounds the water basin be integrated. In addition to the connection of the water basin and the insert basin from the side under the basin, there is also the connection of water and / or air supply lines possible from above the water basin. At least one of the media air and / or water is fed to the insert basin 38 via the connection piece wherein the pressure generator, fan or pump, is connected via the connection piece or the water basin.

Such insert basins, as well as any type of new basin, can be used to reduce of the water volume have formations 4o, as are provided in so-called luxury tubs and behind which the cavities 3 and / or 4 run. Every The type of cavity between the old basin 39 and the insert basin 38 can of course be designed and used as a channel.

The variant shown in Fig. 7 carries flat under the pelvic floor Channels 3 and / or 4. In this example there are two water channels Channels 3 and between them channel 4 are provided for the air supply, wherein the nozzle combinations 7 arranged above the water cavities 3 are supplied with air from the channel 4 via connecting pieces 31. The channel 4 can be ventilated via a line 26 to the edge of the tub. Of course, such floor nozzles can also be approached individually with pipes and hoses will. The channel 4 can be ventilated via the line 26 towards the edge of the tub. It is particularly advantageous, in particular, to have the control nozzles directly in the nozzle to form built-in check valves, also manually adjustable Shutter valves, which can also be regulators, are conceivable. In a further embodiment it is proposed, in particular in the case of floor nozzles, the air and water outlet parallel to the pool floor and the air and / or water irradiation to make a star shape.

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 the size of the air bubbles. The device 56 can by *; the carrier flange 9 are held, but it is also conceivable to use this. to attach a steering beam insert.

In Fig. 9, a nozzle combination is shown, which is in turn fastened in the basin wall 1 and is formed by the nozzle body 35, which on the one hand carries on the inside of the pool radial openings 43 for the water inlet and on the other hand has an inlet 42 for air on the inside of the channel. Compressed air is fed to this nozzle via the inlet 42, which is the via the Opening 43 water entering directly from the basin in the manner of Bernoulli- ' Principle and immediately flows back into the pool.

12 shows a support flange 9 which is equipped with an internal thread 19 can be, over which an axially adjustable nozzle carrier 14 is guided is and through which the nozzle 13 is held beam deflectable. The nozzle 13 is formed with a spherical Obetflache 23 which is pivotable is stored in the nozzle carrier 14. 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 constriction on the annular channel 29. The nozzle carrier 14 can are screwed into the carrier flange until the Water flow is interrupted. It goes without saying that this is also the case with this construction It is conceivable to design the shut-off for both water and air via a check valve or a seal. According to the invention proposed, for example, to design the nozzle 13 by a sealing ring that opens when the water pressure is applied and when the water pressure drops between Nozzle 13 and the air supply pipe 11 seals. Also the use of a spring-loaded Baffle plate at the outlet of the nozzle 13, which prevents both the water backflow in channel 3 and channel 4, is possible, for example.

Di ^e Fig. 13 shows a further variant of the steering jet nozzle, which can also sit in a support flange 9, but installation directly in the pool wall 1 is also conceivable. The nozzle 13 is now guided into a partial ball 15 via a screw thread. Instead of the thread, a ruf can of course also be used

I use a pressure-adjustable nozzle part, which is preferably made by means of | O-ring is sealed. By rotating or shifting the insert part 13j, which represents both the nozzle part and the deflecting socket, against the air nozzle 11, the free cross section of the annular channel 29 is changed. The attachment of the spherical body 15 is preferably carried out as described for FIG. The unit is interchangeable.

Fig. 14 shows a variant of a nozzle, which both a rigid, as can also have a directionally adjustable, as well as regulatable water outlet and also forms a fan-like jet. According to the invention proposed to design the nozzle 13 with a slot-like water outlet, the slot-like outlet 16 being molded onto a ball can, but it is also conceivable to equip both the nozzle with FIG. 13 and this nozzle instead of a ball with a disk 17 with which the nozzle 13 is held and performed. The disk 17 can be swiveled out provided that it is held in a spherical bearing Washer on its circumference an O-ring seal, which against the spherical Bearing sealing causes.

15 shows an embodiment of a nozzle according to the invention, which a on the air supply nozzle 11 mounted rotor 21 at the same time also carries the Forms nozzle 13 and driven by the pressure of the water, one at its outlet constantly circling ray draws. The carrier flange 9 is designed so that the rotor 21 is held via the internal thread 19. About an additional Outlet gate 44, which at designated points 45 the exiting water and / or interrupts the air jet, the jet can be pulsed. It is also possible to mount the rotor radially or the nozzle combination to supply the water axially as well as radially.

16 shows a variant of a nozzle which, on the one hand, is converted into a Water basin can be used, on the other hand can also be used in pools of the known type. In a preferred embodiment, the nozzle combination carries a connection part on the back of the basin 57 which is connected to the nozzle carrier 9 and like a screw closure the basin wall 1 clamps sealingly. The connection part 57 is formed with at least one connection for the air supply 58 and at least a connection for the water supply 59. The connections 57 and 58 lie one inside the other and are designed for the connection of a pipe-in-pipe system. The pipe-in-pipe connections can be designed on one side or on multiple sides in the manner of a distribution on the connection part 57. Inside the connection part 57 carries a nozzle 11 axially to the nozzle body 9 via which air or water can be supplied. The second becomes radial or coaxial Medium stirred in that is not introduced through nozzle 11 (water or Air). The leading out of the inner tube, which can be used either for the Transport of air, which can also be used for transporting water, is preferably carried out at the distribution of the connection piece 57. The lead out can, however, also take place at a rear connection 67 (dashed line) or at any other point within the System. Furthermore, FIG. 16 shows a further nozzle 66 through which, depending on Water and air ducting, one of the media, is introduced into the inner tube 58 can be so that, for example, when water is supplied through the nozzle 66, an axial water jet is formed, the coaxial or radial air entrains, so that a water-air mixture is already within the nozzle 11, which when exiting at nozzle 11 again coaxially through the nozzle 13 exiting water jet is accelerated. Of course, a reverse water and air flow is also possible. By this beam splitting a particularly good water-air mixing is achieved, which makes for a special pleasant hate effect with a soft, widely spreadable jet.

Of course, a fan can also be connected to the connection part 67. In the further development, the outlet nozzle 11 can be equipped with a single distributor device (Diffuser) 60 with a multitude of small openings (pores)

61 are designed. The nozzle 13 can also carry such a device. ,, -, 5 Of course, a check valve can also be installed in this nozzle combination which, especially when using a fan, the water reflux prevented into the air line. The nozzle combination can be used

Additionally can of course also provide at least one axially acting outlet opening 7o be. The nozzle carrier 9 preferably holds a removable cover 67 which can have rotatable lateral interruptions which the outlet of the medium and which are preferably opened and closed by rotary movement can be. The nozzle carrier 9 can of course also be connected via a hose line 26 via which the connection is closed a pressure generator, preferably a blower, takes place.

The medium outlet openings 69, 7o in a star-shaped arrangement cause a rotation the ball 66 which rotates alternately in the housing and covers the outlet openings and thus causes a pulsation of the medium.

Fig. 19 shows a further nozzle variant, which is also preferably used for the supply of compressed air is used. In a support flange 9 in the pool wall or the pelvic floor is clamped, a cover valve 72 sits which, in the rest state, runs almost at the same height as the installation level and when there is a pending Pressure is lifted from its seat 73 and clears the exit path for the medium. The cover valve 72 moves into its valve seat when the medium pressure drops deferred. This can be done by the pending water column in the inner basin, or by its own weight or by spring force. Additionally can the nozzle variant can also be equipped with a non-return ball 66.

The cover valve 72 is mounted exchangeably in the carrier flange 9, the medium outlet the cover valve 72 can revolve without interruption, which is a ring-like Jet shape is conditional, but the medium outlet can also have interruptions show what leads to a radial or star-shaped beam shape. That
