Fig. 1

The circulation pump 1 and the flow system are at least partially arranged in a ring around the water basin 2 , which can be a bathtub. The pressure side 3 of the pump 1 is connected to at least one valve, but preferably to a multi-way valve 4 . At the connection 5 , the pressure line 6 is connected, which leads to at least one jet nozzle 7 in its course. The multi-way valve 4 , which can be a four-way valve, for example, is adjustable by an actuating axis, preferably with an actuating lever 8 , preferably with an actuating motor 9, in accordance with the desired mode of operation.

The multi-way valve can, for example, also be preferred by one or more individual valves are formed by multi-way valves. Several valve outputs are also conceivable. As well Individual valves that work in alternation.

A valve body 10 , preferably in a cylindrical shape, is arranged within the housing of the jet nozzle 7 and is movably guided by the flowing transport medium against the preferably frontal coaxial valve seat 11 . The valve body preferably carries two O-ring seals 12 radially. The medium is radiated into the inner basin 14 through the opening 13 .

The circulation pump 1 is connected to the water basin 2 by the suction line 15 . The normal bathing operation is preferably characterized by the operation suctioning out of the water basin, accelerating the circulating water by pump 1 and jet into the inner basin 14 , with or without the addition of air. The four-way valve guides the medium from A to B.

At the connection 16 , the pressure line 17 is connected, which in its further course leads to the connection 18 of the jet nozzle 7 . By moving the multi-way valve 4 to the position AD, the pressure line 17 is flooded and the pressure line 6 is released via the connection 5 in the direction BC. The line 20 leads from the connection 19 to the suction line 15 .

The medium located within the line system is accelerated by the circulation pump 1 and pushes the valve body 10 out of its seat 11 . The valve body 10 radially closes the irradiation mouth 13 . The flow leads via the pressure line 6 back to the multi-way valve 4 , passes position BC there and reaches the circulation pump 1 or the closed circulation circuit again via the suction line 15 . The circulation can detect one or more single jet nozzles I, II, III etc., which are preferably arranged in parallel. The feed lines for both media preferably run in parallel.

The line section 20 is cut off from the circulation during normal bathing. An addition point 22 is arranged within this section, via which addition substances, for example chemicals, can be added to the circulation circuit. The metering can take place via an injection effect, via a float valve or via controllable valves of the known type. A standpipe is also conceivable, which empties added substances into the system when the circulation medium is operated.

For a circulation operation independent of the pool water content, the suction line 15 carries a holding valve 30 which can be a check valve which is opened by the suction power of the circulation pump 1 during normal bathing operation, but is cut off by the line section 20 during circulation operation, so that the pump suction power does not close the holding valve can open It is also conceivable to use a piston valve, which moves the line 15 in the direction of the inner pool by moving the flushing agent pressure from line 20 . The resetting can be effected by spring force or pump suction power as soon as the direction of flow is changed via the multi-way valve 4 .

What was described above for a liquid medium in connection with a circulation pump naturally also applies analogously to gaseous medium in connection with a blower 63 , as will be described in the following.

The start of the flushing phase can be initiated when the pump suction line 15 is supplied with flushing liquid. When using a holding valve 30 , the flushing operation can be extended. The liquid rinsing phase can be followed by a compressed air powered rinsing phase.

In a further embodiment according to the invention, it is proposed that within the Circulation system to create a rinse water supply in the detergent immediately can be added or can be added to the cleaning agents. The use is advantageous also the features described above, which can be provided in combination.

The line 20 is preferably assigned a container 31 , which serves both in an open, ie unpressurized manner and in a closed operating mode, as a collecting container for rinsing water. The container 31 is connected to the circulation pump 1 . Preferably in direct connection in the form of a compact unit.

The compact unit preferably has its own drain connection 41, and a drain pump is also conceivable. However, it is also possible to arrange a connecting line 33 between the container 31 and the circulation pump 1 . The entire system can preferably be emptied via the container 31 , and any type of controlled valve can be used.

In a further variant according to the invention, compressed air is supplied to the circulation system, which is supplied with additives for disinfection, etc. For example, compressed air can reach the nozzles I, II, III via line 24 . The supply of compressed air via line 17 is also possible, the functions described above being obtained accordingly. It is advantageous to use the compressed air generator that is used to produce the air bubble in any case in a large number of hydro massage pools. The only thing left to add to the airflow is a cleaning solution that can be mixed in with an atomizer.

According to the invention it is proposed to arrange the line system in such a way that Residual water can be blown out using compressed air and residual water can be discharged into the sewer. It is conceivable to arrange an air separator in front of the duct connection.

Fig. 3

The nozzle housing 21 is preferably clamped to the water pool wall 56 with a flange 53 or a thread and has a supply line for liquid 23 and a supply line for air 24 , a driving nozzle 54 which is arranged in the direction of emission toward the inner pool 14 . A standpipe 48 is integrally formed on the nozzle housing 21 . From the nozzle mouth 13 , which can also carry a steering jet insert in its extension, a through hole 49 is provided to the interior of the nozzle housing, which carries a seat 50 inside the housing for an outlet closure, preferably for a float ball 43 .

When the water tank is empty or the water level is low, the float ball 43 lies in front of the nozzle mouth. When the water tank is filled, the ball floats in the direction of the standpipe 48 or a standpipe-like extension, the spatial size of which is such that the float ball can be accommodated therein without this substantially deflecting the liquid jet emerging at the propulsion jet nozzle, thereby releasing the nozzle mouth. In flushing operation with a low water level, the float ball sits in front of the nozzle mouth. The flushing agent pressure guides the ball against the seat 50 . The flushing agent floods the air supply line 24 , which can be flooded and circulated.

During bathing, the floating ball is held by the liquid jet, so that the outlet opening of the nozzle remains open even when the standpipe is emptied during bathing. The return of the float ball into the seat 50 remains prevented as long as the liquid jet emerges from the propulsion jet nozzle and the falling weight of the ball cannot interrupt the jet. The seat 50 can be screwed into the neck of the nozzle housing, but it is also possible to mold the seat 50 to a device that serves to deflect the jet, for example to a nozzle ball.

Fig. 4

The blower 63 generates compressed air for air bubbling operation.

Drain 70 serves towards the channel. A supply container 31 is preferably connected into line 67 , from which container one or more addition substances can be added during circulation mode of operation. The addition can take place by injection or via a controlled valve which controls the outlet from the container 31 accordingly. However, it is also conceivable to apply compressed air to the storage container 31 and, for example, to introduce or spray the added substances into the line 67 by means of compressed air. For this purpose, it is only necessary to connect a pressure line 73 to the container 31 in addition to the suction line 72 and to apply blower pressure to this line. A separate pressure generator, preferably a pump 55, can be connected to the reservoir, through which pressure generator flushing agent can be introduced into the circulation circuit. It is advantageous to have each air bubbling operation first followed by a liquid rinsing phase and then a compressed air-operated rinsing phase, with residual water of any kind being expelled from the supply system in the last rinsing phase, which residual water can be discharged from the collecting container 68 to the channel together with the liquid detergent. However, it is also conceivable to keep the liquid detergent in a separate circulation circuit and to feed it back to the storage container 31 . It is proposed to connect the collecting container 69 to the storage container 31 by means of a circulation line.

According to the invention, it is proposed to provide the various line systems for water and / or air supply with their own circulation pump 55 , via which the circulation medium can be circulated independently of any other mode of operation.

It is advantageous to choose a small pump as the circulation pump that has a low level Energy consumption and with much less noise the independent Circulation takes over. The circulation pump can also be used to evacuate Serve residual water, it is easy to control and can be automated in a workflow Program.

A connection to an existing pressure line, such as a water line or compressed air line, can of course also be used as an additional pressure generator. The pressure generator 55 can thus also be a corresponding connection to an existing pressure line.
