Description

The invention relates to a bubble bath, with a bathing basin installed in the jet nozzles, which are connected via connecting lines to at least one pressure generator, via which, for the purpose of air bubbling, air or water and air into which water located in the bathing basin is blasted. In the medium supply lines between the pressure generator on the one hand and the nozzle mouth in the inner basin, on the other hand, controllable path closures that close the flow path and open the flow path are installed, which, according to a specifiable working rhythm, cause the flow path (s) to be opened and / or closed.

Such whirlpools are known in many ways. A hot tub is known from EP 209646, the jet nozzles of which are equipped with closable nozzle orifices. The nozzle mouth is opened by axial movement of a closure body which opens the nozzle mouth as a result of the pressure of a flowing medium and closes the nozzle mouth as a result of hydrostatic or spring force.

From DE 2703704 a medical bathtub is known which is used to carry out automatically underwater massages. The massage effect is generated by a water jet. A large number of single-jet nozzles is assigned a solenoid valve which is actuated by a program control device with a shift drum.

Known water basins have the disadvantage that the closure of the nozzle mouth seals only unreliably or can only be reached via expensive valves with servo control. Valves controlled by the flowing medium have the disadvantage that a relatively high admission pressure must always be present until the valve closure opens the flow path.
Nozzle mouth closures that are opened by the pressure of the flowing medium are not controllable. In particular, these closures have the disadvantage, when using a feed-irrigation system that is independent of the inner basin, that even at low pressure of the detergent the nozzle openings open and detergent can run into the water basin. This is particularly the case when the spring pressure and limescale decrease. Furthermore, a certain force of the pressure generator (blower, pump) is required to effectively open the nozzle mouth against the spring. The coordination between the desired spring-closing force which is required in flushing operation and the opening force and the pressure force of the pressure generator desired for the massage effect is extremely difficult and has the consequence that a correspondingly strong pressure generator must be used. Sealing surfaces which are usually made of rubber-elastic material offer bacteria etc. ideal culture media, disadvantageously in known valves, the sealing surfaces are only one side of the flushing u. Detergent detected.

The present invention has for its object to provide a water basin of the type mentioned, in which the supply of the air to be blasted is controllable and the nozzle orifice closure both at low medium pressure, for example when supplying compressed or suction air as well as at high medium pressure from the pressure generator acts, does not open or in both cases only opens at a definable point in time, and that the device causing the closure of the flow path can be produced inexpensively and is also service-friendly. It should also be ensured that the rubber-elastic parts serving as sealing and sealing surfaces are exposed over their entire surface to the flowing medium or the detergent. The cleaning of the flow paths and the double-sided cleaning of sealing surfaces is also important in systems that do not have their own circulation system that is independent of the indoor pool and that are only operated with compressed air, for example.

This task is solved by the characteristic features of the main claim.

The design of the water basin according to the invention with the features described in the characterizing part of the main claim has the advantage that the opening and closing of the medium flow path to the jet nozzles takes place independently of the medium pressure present and is controllable. The diaphragm, which is designed in the form of a bead or bellows as a spring force accumulator, on the one hand advantageously opens a large passage cross section, on the other hand the spring force moves the membrane sealing surface into its closed position in the depressurized state.

The supply lines can advantageously be subjected to high flushing agent pressure without flushing agent reaching the inner basin from the nozzle orifices. Flushing agent advantageously also reaches the control side of the membrane through the pre-pressure flow path in order to kill or rinse out bacteria, etc. there. Only low electromagnetic forces are required to effect the closing or opening process by relieving pressure.

The bead-like or bellows-like design of the membrane has the advantage that the membrane can be moved axially over a long stroke and the free flow cross section of the flow path in the vicinity of the valve seat is expandable even at low pressure.

It is also possible for a plurality of single-jet nozzles combined to form a group to form a bubble zone, the various groups being controllable by a predefinable program. It is advantageous to divide the bathing pool into bubble zones which are supplied with the irradiation medium one after the other or in a different order or in which the irradiation acts for regional treatment, while other zones within the bathing pool serve and are designed as relaxation zones.

The embodiment according to the features of claim 4 has the advantage that a large number of bubble patterns can be formed and, on the one hand, cause a constant as well as a changing or a local massage and the desired type of massage can be selected.

The embodiment according to the features of claim 6 has the advantage that the medium main flow channel is divided into a plurality of individually controllable partial flow channels and the different partial flows can be supplied to the bathing pool in different cycle times and cycle rates.

The embodiment according to the features of claim 7 has the advantage that the pressure chamber of the pressure generator carries several controllable outputs and the flow channels leading to the jet nozzles are directly connected there.

The embodiment according to the features of claim 8 has the advantage that the membrane used to close the flow path is built into or attached to the nozzle housing in a compact design and the mouth of the nozzle can be closed.

Advantageously, two membranes can also be assigned to the nozzle housing, each membrane being controllably used to close its own flow path.

The different flow paths can flow separately or together into the inner pool. Within the nozzle housing, the channel leading to the nozzle mouth is preferred as an annular channel trained, this has the advantage that the flowing media mix.
The medium outlet channel is preferably designed as a water jet pump, with at least the drive jet supply being assigned a controllable membrane which closes the medium flow path.

The embodiment according to the features of claim 9 has the advantage that a second medium or a detergent can be transferred through the relief bore into the flow channel and that the principle of the water steel pump can be used, after which the second medium is sucked into the flow channel by negative pressure.

The embodiment according to the features of claim 10 has the advantage that a venturi nozzle is formed by the annular channel and two different media are guided both by pressure and by negative pressure in the direction of flow and that each flow path can be blocked or controlled.

The embodiment according to the features of claim 11 has the advantage that the medium jet can be widened and / or directed into different zones, that the nozzle mouth and the membrane are protected by a cover.

The embodiment according to the features of claim 12 has the advantage that the lid forms the sealing seat and the support for the membrane and the seal is made directly below the lid, this has the advantage that no residual water remains in the flow channels after emptying the water basin .

The embodiment according to the features of claim 13 has the advantage that a detergent can be circulated through the entire flow system for cleaning purposes, regardless of the inner basin, and the medium flow channels serve as detergent circulation channels.

Description of an embodiment:

According to the invention it is proposed to arrange the jet nozzles in columns within the bathing pool, which are essentially distributed over one or more longitudinal axes. The nozzle arrangement is preferably carried out in pairs or in groups of three or four, which essentially form a zone transverse to a longitudinal axis of the bathing pool, which is followed (or is followed) by one or more zone (s).
Each jet nozzle or group of jet nozzles receives at least its own medium supply line and at least one controllable membrane which opens or closes the medium supply to the jet nozzle mouths.
Depending on the size of the bathing pool, the preferred number of jet nozzles must be defined and divided into controllable individual zones.

1 shows, by way of example, the arrangement of pairs of single-jet nozzles which are arranged on two longitudinal axes of the bathing pool. The longitudinal axes are divided into 4 bubble zones. Each of the images shown represents a specific bubble image, which is generated, for example, with 8 single-jet nozzles. The jet nozzles are divided into zones I, II, III, IV. The examples 1 to 4 shown each show bubble images which are generated in succession with 2, 4, 6 and 8 single-jet nozzles. The bubbling jet nozzles are symbolized with arrows, non-bubbling jet nozzles are shown with a circle.
Example 1 shows the start screen. The pair of single jet nozzles in Zone I is in operation.
After a preferably predeterminable operating time, for example after 3 seconds, the connection of the single-jet nozzle pair arranged in zone II follows, the switching in of further zones III follows at intervals, etc.
The bubbling patterns can be repeated, the cycle sequence can preferably be specified, and pause times can preferably be selected between the individual operating phases. It is also possible to stop the clock sequence and use the current bubbling pattern unchanged for a long time.

Of course, it is possible to control the individual zones with each other in a different order or to operate the columns in the right / left jet rhythm.

In the case of a further bubble pattern, it is possible to pulse zones I, II, III, IV in succession, for example by assigning a bubble break to each zone in a continuous cycle.

In another bubble pattern, all nozzles continuously emit pulsed air, this bubble pattern results in the "on / off" operating mode in continuous operation

The medium radiation can also alternate pulsating from jet nozzle to jet nozzle or between pairs of jet nozzles, the pause times preferably being predeterminable. Such an operating mode is characterized by a number of continuously operated jet nozzles, while another number shows pulsed radiation.

Of course, continuous operation in any desired irradiance between a maximum and a minimum value is also possible. Likewise, with the method and its device according to the invention, further bubble images and radiation combinations can be generated and used.

2 schematically shows the pressure generator 1, which is connected with its pressure side 2 to the control device 3 via at least one feed line carrying the medium flow. A flexible hose line is preferably used as the feed line. The control device 3 carries at least 2 medium outlets 4 which can be closed with controllable sealing membranes. In the further embodiment, the medium outlets 4 are designed as pipe sockets or sleeves for connecting the medium supply lines leading to the jet nozzles 7.

In another exemplary embodiment, not shown, the control device 3 is built directly into the pressure generator housing 16 or is attached to it. The main medium flow is fed directly to the directional locks within the pressure generator housing; in their further configuration, they form a plurality of controllable outlets 4 on the pressure side 2, preferably in a radial or in a radial / parallel arrangement to the pressure axis longitudinal axis.
In order to actuate the directional locks, 16 working magnets are attached to the outside of the pressure generator housing.

The working magnets 25 are connected to the electronic control circuit 8 via an electrical supply cable 17. Within the control circuit, the input signals or a predefinable program are implemented with electronic means and passed on to the actuators (working magnets). A microprocessor is preferably used, in which the various programs are entered; the program is preferably called up via a keyboard clamped at the edge of the bathing pool, via which the work cycle sequence of the directional locks and the power of the pressure generator can be called up via low-voltage control currents.

According to the invention, the operation of the pressure generator and the directional locks takes place from an input keyboard, which on the one hand carries keys as signal transmitters, which are designed to call up the pressure generator output, and leads via electrical lines to electronic means, for example to a stepless speed control or to a series of switching stages, each with a different speed, which switch the pressure generator.

On the other hand, the input keyboard carries keys as signal transmitters which serve to control the directional locks and lead via electrical lines to electronic means, for example to a cycle sequence program control which is designed to successively open and close the directional locks in preferably predeterminable time cycles. Furthermore, the input keyboard carries keys as signal transmitters, which are used to change the time cycle and lead via electrical lines to electronic means, for example a controller, which is designed to accelerate or delay the switching clocks and which follow the signal of the input key and the opening time and / or The closing time of the path lock (s) is determined by the fact that electronic current is delivered to the movement devices (solenoid) of the path locks over shorter or longer periods of time. Furthermore, the input keyboard carries at least one key, which serves as a signal transmitter for intermittent single-beam operation and leads through electrical lines to electronic means, for example a control unit, which preferably delivers electrical current to the movement devices of the directional locks in predeterminable time cycles, and this continuously opens and closes the cause (des) medium flow paths (s).

The electronic means are preferably designed as microprocessor (s), which are programmable and, following the control signals, emit the stored program in the form of electrical currents to the intended work contacts.

In a particularly preferred embodiment, the input keyboard is formed in two columns of pushbuttons which are arranged parallel to the sides or in a continuous row, one of the columns being designed to emit signals which are used for program control. The first column consists of a pushbutton whose signal starts and preferably stops the pressure generator and secondary pushbuttons whose signals call up the speed of the pressure generator in steps between a maximum value and a minimum value.
The second column consists of a button that starts and preferably stops the cycle sequence program and sequence buttons whose signals call up the cycle sequence time of the cycle sequence program between a shorter and a longer cycle time in several stages. (1 second cycle time button 1, 3 seconds cycle time button 2 etc.

Another signal key is used to call up the interval operation, the switching function interval operation is preferably superimposed on the switching function cycle time change, so that the cycle time sequence of the interval operation can be selected on the input buttons.
For speed control and cycle time control, the number of sequential switches is preferably equipped with 2 to 10 buttons.

In a particularly preferred embodiment, the input buttons are provided with a light which indicates the respective operating state and, by the lighting up of an optical display on the respective button or on a separate light field, the respectively selected power or the respectively selected time or both functions.

Instead of several sequential pushbuttons, it is of course also possible to use a multi-function pushbutton that emits a specific signal when pressed briefly and, when pressed longer, triggers a signal sequence that triggers power regulation or a temporal change in the clock sequence.

The pressure generator 1 has an electronic control circuit 18, by means of which an on-off switching is possible and which preferably regulates the speed of the pressure generator motor between a minimum value and a maximum value. In an advantageous embodiment variant, control circuits 8 and 18 are combined into one unit and accommodated within the pressure generator housing in an integrated switch box 24 designed for this purpose, the pressure generator housing and switch box forming a structural unit.

Fig. 3 shows schematically the connection diagram of jet nozzles which are clamped in groups (C) to (F) at the bottom of a bathing pool, transversely to its longitudinal axis AB. Each of the groups (C) to (F) is connected via its own supply line 50, 51, 52, 53. The feed lines lead to the control device 3.
In contrast to the system shown in FIG. 1, where a feed line 6 leads to each jet nozzle, in this variant each group is assigned its own directional closure 5. Each group can be controlled via the assigned path lock.

The control device is equipped with a main connection 55 which leads to the pressure side 2 of the pressure generator 1 or which passes directly from the pressure generator housing into the control device.

Fig. 4 shows a preferred detail of a way closure body 22 with electromagnetic coil part 25, magnet armature 26, compression spring 27, and sealing membrane 28 which essentially seals the medium inlet channel 32 against the medium outlet channel 33 with the surface area located in its center. The medium inlet channel preferably merges into an annular channel 34 in the area of the membrane sealing seat 29; it essentially surrounds the membrane sealing seat 29 formed in the center, which in its further configuration merges into the medium outlet channel 33.
In the further embodiment, the path closure body housing carries a radial membrane clamping seat 30 in addition to the central membrane sealing seat 29. The membrane divides the annular channel 34 into a pressure side 22 with a medium inlet channel 32 and the rear side of the medium outlet channel 33, which is from the central membrane sealing seat 29 leads in a channel-like configuration to the jet nozzle 7 and on the other hand in a membrane control side 21, on the the compression spring 27 and the magnet armature 26 is arranged.

The sealing membrane is preferably designed in the form of a bead or bellows as a spring force accumulator, it is clamped on the radial diaphragm clamping seat 30 in a gas-tight and liquid-tight manner and is preferably embedded in a radial groove 35. The sealing membrane is radially clamped by a base 36 which also carries the electro-magnetic coil 25 and which is clamped by screws 37 to the way closure body housing 31.
The sealing membrane covers the medium inlet channel in a hat-like manner in the area in which it is designed as an annular channel and at the same time covers the membrane sealing seat 29 or the inlet into the medium outlet channel 33.

As soon as the magnet armature picks up, the pressure of the flowing medium lifts the membrane from its valve seat 29.
The membrane is preferably loaded in the center against the flowing medium by the compression spring 27 and pressed against the membrane sealing seat 29 in the idle state. The sealing membrane is preferably equipped with at least one through bore 38 which leads from the membrane pressure side 22 to the membrane control side 21. The pressure of the entering medium is used as a diaphragm contact and control pressure. The bore 38 is preferably designed such that medium can only pass through the bore from the diaphragm pressure side 22 to the diaphragm control side 21 in one direction of flow. This is achieved in that, for example, the sealing membrane has a double layer in the area of the bore, the double layer acting like a non-return valve. Incoming medium lifts the flap, in the event of a backflow of medium the flap closes and blocks the return flow path towards the diaphragm pressure side. Sealing membrane and the double-layered design or the flap device are preferably made of an elastic and sealing material. The existing medium pressure passes through the bore 38 to the diaphragm control side 21 and relieves the diaphragm.
The membrane sealing seat 29 is opened by the lifting movement of the magnet armature 26, which tensions the force of the spring 27.

The sealing membrane is preferably provided with a second bore 39 which lies in its center. On the diaphragm control side 21, the magnet armature 26 covers this bore in its rest position, preferably the magnet armature is formed like a dome at its end 40 and equipped with a sealing material. If the magnet armature is tightened, the sealing membrane is relieved. The control pressure escapes through the path which the bore forms from the membrane control side to the medium outlet channel 33.

In the event of overpressure from the direction of the pressure generator, the pressurized medium passes through the path which the bore 38 forms on the diaphragm control side 21 and pressurizes the diaphragm in the direction of the sealing seat 29. In the event of overpressure from the direction of the bathing pool, this occurs medium flowing towards the pressure generator through the path that the bore 39 forms the dome-like formation 40 of the magnet armature 26 and lifts it out of its seat. The flap-like closure device closes the path of the bore 38 and the flow pressure of the medium acts on the membrane in the direction of the sealing seat 29.

The closure body housings are preferably designed such that they have a central medium inlet 55 and a plurality of media outlets 4 and can accommodate a plurality of path closure bodies, for example in the form of sealing membranes 28. The closure body housings are preferably made of a plastic or a non-ferrous metal.

Preferably, the directional closure body housing 31, which is designed as the seat of the sealing membrane, carries at its entrance in the direction of flow a screw thread 41 which engages in the wall of the multi-way control device and is attached there pressure-tight and tight. According to the invention, however, it is also possible to incorporate the closure body housing with the clamping seat 29 of the membrane, with medium inputs and medium outputs directly into the control device, so that a unit is formed which is designed both as a distributor of the volume flow and as a closure body housing, in which only the Membrane and the electromagnetic coil part is used. It is also conceivable to design the pressure generator housing 16 in such a way that the closure body housings with the seat for the membranes are designed directly in the walls thereof.

5 shows a further particularly preferred embodiment of the invention. Based on the illustration, two variants are shown. The right half of the illustration shows a single-jet nozzle 7 in which the directional closure according to the invention in the form of a sealing membrane 28 is installed directly. In the left half of the illustration, an additional embodiment is proposed which, in conjunction with the variant shown on the right, is designed for the simultaneous or separate supply of a second irradiation medium. Different irradiation media, such as water and air, are provided for separate or joint irradiation.

Right variant: A plurality of connecting lines 6 are connected to the pressure generator housing 16, which can be a pump or a blower, in the direction of flow in the manner of a distributor. The connecting lines 6 lead to several jet nozzles 7, which are clamped to the bottom of the water basin or the walls thereof.

Each jet nozzle is equipped with its own directional closure 5 in the form of a sealing membrane 28 with compression spring 27 and electromagnetic coil 25.
The jet nozzle 7 carries a connecting part 44 which is preferably designed as a hose nozzle or thread, which leads into the interior of the jet nozzle like a channel and is designed to supply an injection medium.

The medium outlet channel is preferably divided into a plurality of individual outlet channels, which lead from the center to the radially outward towards the medium irradiation orifices 45 and are arranged below an attached cover 42. The medium outlet channels are preferably incorporated into the front cover 42 or formed between the cover and the closure body housing.

However, it is also possible to design a single-jet nozzle which is only equipped with an axial medium outlet without a cover. It is conceivable in both variants to additionally form a nozzle orifice closure, which is opened by the pressure of the flowing medium in the direction of the inner basin 43 and closes the nozzle orifice in a depressurized state.With the path closure according to the invention, the closure body remains closed even when pressurized with medium pressure and only then The opening or closing takes place via the additional control and actuation of the closure body.

It is preferred to design an annular channel-like circulation below the lid 42, from which the individual outlets or a slot-like outlet running around the lid opens into the inner basin 43. The opening and closing of the path closure or the sealing membrane 28 is carried out as described above and with reference to FIG. 4.

The position of the sealing membrane 28 can be arranged essentially both at right angles to the mounting plane of the jet nozzle, and also essentially parallel to the mounting jet plane, which runs approximately parallel to the cover 42. In the case of an arrangement of the sealing membrane parallel to the lid, the side of the lid 42 facing away from the inner basin 43 is particularly preferred for supporting the sealing membrane 28. The cover preferably carries an annular material formation which forms the valve seat 29 and on which the sealing membrane 28 is supported in its closed position; medium outlet openings lead from the annular material formation into the inner basin 43.

Left variant: in the left part of the illustration, a further path closure body housing is shown, which is used to feed a second medium, the medium outlet channel 33 B of which opens into the medium outlet channel 33 A of the closure body housing shown in the right half and preferably at least one at the transition of the two channels Venturi forms. While the variant shown in the right half, viewed in isolation, is designed for feeding, blocking and irradiating one medium, both variants are designed together for supplying blocking and irradiating two different media, with each medium having its own medium input channel 32 A and 32 B is provided and for each of the media a separate path closure, preferably in the form of a sealing membrane 28 A and 28 B is arranged.

One of the medium outlet channels is preferably designed in a ring-like manner around the other medium outlet channel, so that one or more Venturi nozzles form at the transitions, the principle of the water jet pump being used. However, it is also possible to accelerate the second medium by means of an additional pressure generator and to feed it to the nozzle unit.

Hydromassage jets based on the principle of the water jet pump are known, the principle need not be described here, the only important thing is that one of the medium-carrying channels 33 A or 33 B is designed for supplying the propellant jet, and the other medium-supplying channel is designed for supplying the catch jet.

Preferably, the two sealing membranes 28 A and 28 B are installed in a common closure body housing, so that a housing unit is formed which reaches through an opening in the pool bottom and is clamped there liquid-tight, and is formed on the side below the pool for supplying the media and on the side facing the bathing pool for the irradiation of the media and is provided with at least one irradiation opening.
If both media paths are designed so that they can be shut off, each medium path is also assigned a sealing membrane 28, a magnetic coil part 25 with a control option, as described above.

The sealing membranes 28 A and 28 B are preferably arranged pressure side to pressure side, essentially parallel to one another, the center line running through the path closure body housing running essentially parallel to the surface diameter of the two path closure bodies.
However, it is also possible to choose a different surface arrangement, for example the path closure bodies can also be arranged next to one another or one above the other.
Of course, it is also conceivable to use a path closure for only one of the media when two different media are supplied, while the flow path remains open for the second medium or is opened and closed by a differently designed path closure device.

According to the invention, a further preferred variant is proposed for the irradiation of two different media, two different medium flow channels being sealed within the single jet nozzle housing with only one sealing membrane, and the irradiation being controllable from one or both media.
In addition to the simple embodiment described above for the supply of only one medium, in the following variant, in the radial region of the sealing membrane 28, on its control side 21, a further medium inlet is designed, which has a connection for the supply of the second medium located outside the housing is channel-like and opens into the control room 21. The opening 39, which is preferably arranged in the center of the sealing membrane, is enlarged in its passage cross-section to such an extent that sufficient amounts of the second medium enters the common medium outlet channel 33. The diameter of the opening is preferably between min. 4 mm and max. 12 mm determined. The end cap 40 of the armature 26 is designed to close and to seal the opening in a gas-tight and liquid-tight manner. On the side facing the medium outlet channel, the sealing membrane has a frustum-like configuration which essentially projects into the center of the medium outlet channel 33 and is surrounded by its walls in a ring-like manner. The stub-like design forms, together with the walls of the medium outlet channel, a Venturi nozzle through which the second medium is drawn into the propellant flow channel.
Of course, it is also possible to accelerate the second medium with a second pressure generator. In this way, a larger volume flow of the second medium can be irradiated.
The sealing membrane is closed and opened as described above.
In order to avoid a backflow from the bathing pool in the direction of the second medium supply, a backflow prevention device is provided between the sealing membrane control side and the extension of the second medium supply.

The various exemplary embodiments in which a sealing membrane is used as the path closure body 28 can be combined with one another. One or more venturi nozzles are provided in the case of path closure body housings which are used to feed two different media, the drive jet leading supply line as a venturi nozzle formation, before the subsequent transition to the common outlet for both media, having a cross-sectional constriction at which the speed of the drive jet is accelerated.
In the case of a configuration with a distributor cover 42, a plurality of Venturi nozzles are preferably arranged in a ring-like manner below the cover, preferably a medium is supplied axially with radial deflection of the medium outlet path, which preferably opens into an annular groove arranged below the distributor cover and then leads in the direction of the nozzle mouth 45 and into it Indoor pool 43 shines.
