Definitions

  • the invention relates to a hydropneumatic massage bath with an upstanding side walls and a bottom bath and at least one pressurized water line, which ends in a water jet nozzle, with an air supply line, which opens into a chamber surrounding the water jet nozzle, which chamber has an outlet opening for the water jet and the Has air in the interior of the bathtub, as well as means for pulsating the water-air mixture jet emerging into the interior of the bathtub, an interrupter mechanism which intermittently closes the air supply line and thus influences the supply air flow to the chamber is arranged as a means in the air supply line in front of the chamber.
  • Such a massage bath is known from US-A 4320541.
  • the device shown there for generating a pulsating air / water flow is characterized in that an interference body is pushed into the water jet by means of the piston due to the negative pressure generated by the water jet of the nozzle. Only when this has been done are the openings exposed so that air from the air line can enter the water jet laterally via the opening.
  • This has several major disadvantages. On the one hand, especially when the air can enter the water jet from the side, the water jet is considerably disturbed, while as long as the water jet emerges freely from the nozzle, no air can be supplied from the side. As a result, a satisfactory massage effect cannot be achieved.
  • the frequency with which the interfering body is guided into the water jet and thus also the frequency with which air is supplied laterally depends on the water jet strength of the nozzle. So if the water pressure decreases, the pulse frequency also drops, although in this case it would have to increase in order to achieve the same massage effect.
  • a further disadvantage of the known device is that it has parts which are movable in the water flow and are susceptible to faults, which is the case with bathtub fittings, e.g. because of the risk of calcification, is particularly unsatisfactory.
  • the object of the present invention is to make a hydropneumatic massage bath of the type mentioned in the preamble of claim 1 more effective and reliable with regard to its massage effect.
  • the interruption mechanism is e.g. has a fully or partially closable control valve designed as a magnetic valve, the opening frequency of which can be set independently of the strength of the water supply in the pressurized water line. This enables precise control of the opening frequency regardless of the water supply and the resulting Venturi effect.
  • the water jet emerging from the water jet nozzle is always unaffected by any interfering bodies; it is only supplied with more or less compressed air at a variable frequency, regardless of its strength. Because of the adjustability of the opening frequency and the possibility of opening the control valve more or less, the massage device can also be optimally adjusted to the needs of the user.
  • Another massage bath in the form of a massage cabin is known from DE-A 2 735 578, in which a compressed air line opens into the chamber surrounding the water jet nozzle, the free end of which is connected to a radial pressure blower which has a speed controller.
  • the chamber has a front nozzle with a smaller outlet opening, so that the chamber is designed as a compression chamber in order to pre-compress the escaping pressurized water together with the inflowing compressed air.
  • the water-air mixture should be pressed rhythmically into the pool of the interior of the massage cabin and not be continuously irradiated.
  • this arrangement only leads to an unsatisfactory massage effect.
  • the water jet nozzle surrounded by the chamber creates a venturi effect, as a result of which air is sucked into the chamber from the air supply line and entrained by the water jet emerging from the water jet nozzle.
  • the water-air mixture jet creates a pleasant massage effect for bathers. This becomes particularly reliable and pleasant with the solution according to the invention for generating the pulsation of the massage jet, because in the chamber, due to the intermittent interruption of the air supply, the water jet emerging from the water jet nozzle forms a more or less greatly reduced vacuum which forms the massage jet influenced.
  • the hydropneumatic massage bath according to the invention is thus also considerably more effective, pleasant and less susceptible to faults than those devices in which the water supply to the Venturi nozzle is interrupted with the aid of a valve mechanism or a disturbing body.
  • Such valves in the pressurized water line or interfering bodies are relatively sensitive to dirt.
  • the interruption of the water supply and the disruption of the water jet lead to water hammer effects in the water supply pump.
  • the interruption mechanism can be designed in such a way that the supply air flow is completely interrupted at the desired pulse frequency.
  • the supply air flow change with the pulse frequency from a maximum value to a non-zero minimum value.
  • Both the maximum value of the air supply and the minimum value can be adjustable.
  • By the change alternating full or partial opening of the air supply line creates a changing vacuum in the chamber surrounding the water jet nozzle, whereby the strength of the water-air mixture jet emerging from the chamber varies.
  • the massage effect can be further modified and adjusted to the most pleasant if the pulse frequency of the interrupter mechanism can be controlled.
  • Both the pulse strength and the pulse frequency of the water-air mixture jet can thus be varied by the interruption mechanism in that the operating frequency of the interruption mechanism and / or the opening width of the air supply line can be changed.
  • the control valve of the interrupter mechanism can be assigned a switching mechanism which specifies both the opening frequency and the opening width of the control valve in an adjustable manner.
  • the air supply line is connected to the pressure line of an air compressor, the pressure introduced into the chamber with the air supply line can also be changed and the massage effect can thereby be varied. Otherwise the air supply line only sucks in ambient air under atmospheric pressure.
  • the interrupter mechanism in particular the control valve, should also be designed for regulating a compressed air flow and should be adjustable with regard to pulse frequency and opening width.
  • the pressurized water line is expediently connected to the pressure side of a water circulating pump, so that the supply and discharge of new water is unnecessary. It is particularly advantageous here that the suction side of the circulation pump is connected to the interior of the bathtub, so that the water required for the hydropneumatic massage bath is removed from the bath water in the bathtub itself and fed back in via the water jet nozzle.
  • a water jet nozzle or a plurality of water jet nozzles can be arranged in or on the walls of the bathtub with its chamber or chambers, so that the person in the bathtub can choose from only one Venturi nozzle or all around from several Venturi nozzles is exposed to a massage.
  • FIG. 1 The arrangement shown in FIG. 1 has a water circulation pump 1, for example attached to the bath tub 10, which takes water from the bath tub interior 12 and feeds it to a pressurized water line 2 in the direction of arrow P.
  • the pressurized water line 2 opens into a water jet nozzle 4.
  • the front end of the water jet nozzle 4 projects into a cylindrical chamber 5, which surrounds the water jet nozzle 4 with a predetermined radial distance.
  • Water jet nozzle 4 and chamber 5 thus jointly form a water jet-air ejector device 3 which works according to the Venturi principle.
  • chamber 5 has a front outlet opening 11.
  • An air supply line 8 opens into the rear end of chamber 5 Air is drawn into the chamber 5 in the direction of arrow S via the air supply line 8 to the negative pressure generated in the chamber 5 from the water jet leaving the water jet nozzle 4.
  • a control valve 6 is arranged in the air supply line 8, the air passage opening of which can be changed in the direction of the arrow L. The amount of air that can be sucked in via the air supply line 8 can thus be set.
  • the valve 6 is also associated with a switching mechanism 7, which opens or closes the control valve 6 depending on the specified setting, in whole or in part, with a pulse frequency that in this way exits from the outlet opening 11 and into it Bath water entering water-air mixture jet 9 is communicated.
  • the pulse frequency of the switching mechanism 7 can also be controlled.
  • the water-air mixture jet 9 entering the bathing water shows a pulsating flow valve due to the absorption of changing amounts of air, which causes a pleasant massage effect.
  • the amount of water supplied in the unit of time via the water jet nozzle 4 remains essentially unchanged during the massage process. It is only set to the desired value at the start of the massage process and switched off again at the end of the massage process.
  • the massage effect is set to the most comfortable value for the user by controlling the pulse frequency of the switching mechanism 7 and the opening width of the control valve 6.
  • FIG. 2 differs from that according to FIG. 1 only in that the air supply line 8 not only sucks in ambient air, but that air is supplied to it via the pressure line 13 of an air compressor 14 at a pressure above atmospheric pressure. This results in a further variation possibility for the massage effect of the water-air mixture jet 9.
