Definitions

  • the invention is based on a whirlpool bath, as shown in the previously unpublished older application WO-A-8902263.
  • This whirlpool bath has devices for generating water and / or air jets which can be fed to the bath room at several points on the bath wall and / or the bath floor, each of these places having an individual, drivable device for generating a water and / or air jet is assigned, which can be acted upon from the outside of the tub with drive energy installed in the tub wall and has a nozzle housing with a pump chamber and an impeller arranged therein, the pump chamber being watertight to the outside of the tub and to the tub space by means of a nozzle orifice with a suction opening and nozzle openings is completed.
  • DE-A 24 17 708 describes a whirlpool bathtub with a central pump, which supplies a plurality of nozzles via a suction opening and a line system guided around the outside of the bathtub, through which the water is again supplied to the tub space as a jet.
  • the central pump and the pipe system are also part of generating the water jets.
  • DE-A 22 09 507 shows a circulating device for a swimming pool, which is built into an opening in the pool wall.
  • the circulating device sucks in water from the swimming pool and feeds it via the pump to the centrally arranged nozzle, this nozzle generally being pivotable in order to be able to change the direction of the water jet.
  • a more or less powerful water jet is always emitted, which can only be achieved by changing the output of the pump.
  • the impeller sucks water from the tub space via axial suction openings of the nozzle orifice and supplies at least one channel in the nozzle orifice via radially directed delivery channels from the pump chamber, which channel faces the wall of the peripheral side of the impellers Pump chamber goes out and ends in at least one nozzle opening facing the trough space of the nozzle orifice, and that nozzle orifices with different numbers and different designs of the channels and the nozzle openings can be connected to the nozzle housing.
  • the nozzle orifice forms part of the pump chamber and the impeller radially releases the centrally sucked-in water, it can only be dispensed through the nozzle orifice with the channels and nozzle openings introduced therein. This means that differently designed nozzle orifices are sufficient to determine the type of water jet emitted.
  • the the pump chamber final nozzle orifice is easy to replace and can therefore be adapted to different types of bubble and massage.
  • the pump After removing the nozzle cover, the pump can be easily cleaned.
  • the nozzle orifice with the channel or channels to the nozzle opening or the nozzle openings can also be easily cleaned and kept hygienically clean.
  • the nozzle opening is designed as a narrow, arc-shaped slot. This fan jet is preferred for a gentle massage over the tub floor.
  • the water jet can also be emitted in such a way that a plurality of nozzle openings designed as small-diameter bores are arranged on a circular path, which are connected to the pump chamber via a common channel or via individual channels of the nozzle orifice. This creates several round rays that are intended for a normal massage.
  • a single nozzle opening with a round cross section is provided, which is connected to the pump chamber via a single channel of the nozzle orifice, then a single powerful water jet is emitted, which can be used for a targeted massage.
  • the structural design of the nozzle housing is carried out in such a way that the nozzle housing is composed of the nozzle screen and an engine mounting flange, the nozzle screens provided with different nozzle openings being able to be used in the same way and interchangeably with the engine mounting flange or in an opening in the tub wall or the tub floor Housing ring are connectable and wherein the motor mounting flange itself or the housing ring receiving the motor mounting flange is inserted sealed in the opening in the tub wall or the tub bottom.
  • the nozzle orifices can then be assigned to the locations in the tub wall or the tub floor and can also be easily attached in a different way.
  • the tight installation of the nozzle housing in the tub wall or the tub bottom is solved according to one embodiment so that the housing ring is supported with a flange on the part of the tub wall or tub bottom surrounding the opening that the housing ring with a sealing sleeve in the Breakthrough is used and that a nut screwed onto an external thread of the housing ring, preferably under the intermediate layer of a washer, tightly fixes the housing ring in the opening.
  • the nozzle orifice then closes the nozzle housing tightly if it is provided that the nozzle orifice surrounds the flange of the housing ring with an edge and that in the overlap area a sealing ring seals the nozzle housing and nozzle or housing mounting flange and / or motor mounting flange.
  • a motor mounting flange is provided for the nozzle housing in addition to the housing ring, then the nozzle housing is sealed off from the outside of the tub by inserting the motor mounting flange in the housing ring and sealing it in the overlap area by means of at least one sealing ring.
  • the drive of the impeller of the pump is designed in such a way that an electric motor is attached to the side of the motor mounting flange facing away from the impeller, the motor shaft of which is guided through the motor mounting flange into the pump chamber and connected to the impeller in a rotationally fixed manner and that the electric motor is covered by a housing pot which is connected to the housing ring defined in the opening in the tub wall or the tub bottom.
  • the electric motor with the motor mounting flange can be exchanged from the tub space without the housing pot and the housing ring having to be released from the opening in the tub wall or the tub bottom.
  • a circumferential ring channel is formed, which is accessible through the through hole of a radially connected hose connector, and that starting from the ring channel in the motor mounting flange and the flange of the housing ring air channels are introduced, which are via air channels in the nozzle orifice with the channel coming from the pump chamber are connected and end up as venturi openings in the area of the nozzle openings, then an air jet or several air jets are admixed to the water jet or the water jets in the area of the nozzle orifice. If several nozzle openings are provided in the nozzle screen, then it is provided for the admixture of the air jets that the air channel or channels of the nozzle screen end in an air chamber at which individual channels branch off with venturi openings.
  • the individual device for generating a water jet with an admixed air jet is built into an opening 11 in the tub wall 10. Installation can also be made in a breakthrough in the same way of the tub floor.
  • the sealing sleeve 12 is first used, which partially covers both sides around the opening 11 with flanges.
  • the housing ring 14 is inserted, which is supported with the flange 29 on the inside of the tub wall 10.
  • the nut 16 is screwed onto the external thread 15 of the housing ring 14 with the interposition of the washer 13, so that the housing ring 14 is tightly fixed in the opening 19.
  • the motor mounting flange 23 is fixed, which closes the nozzle housing to the outside of the tub.
  • the sealing rings 19 and 27 are introduced for sealing. Facing the inside of the tub, the motor mounting flange 23 has the recess 40, which forms part of the pump chamber and receives the elements for connecting the impeller 36 of the pump to the motor shaft 31 of the electric motor 18.
  • the electric motor 18 is received by the housing pot 17, which is connected to the housing ring 14 with its open side.
  • the motor shaft 31 is guided through a central receptacle of the motor mounting flange 23.
  • the mechanical seals 32 and 34 in connection with the sealing ring 33 seal the passage of the motor shaft 31.
  • the shaft bush 35 is fixed on the motor shaft 31 in a rotationally fixed manner.
  • the impeller 36 is held with the bearing sleeve 37 on the shaft bush 35 and the screw 39 establishes the rotationally fixed connection between the impeller 36 and the shaft bush 35.
  • the impeller 36 is supported on the mechanical seal 34 by the helical spring 38.
  • the nozzle orifice 41 facing the tub space, closes off the nozzle housing.
  • the nozzle orifice 41 surrounds the flange 29 of the housing ring 14 with an edge, the sealing ring 28 sealing the separation point between the nozzle orifice 41 and the housing ring 14 in the overlap region.
  • the nozzle orifice 41 has the pump chamber 51 in which the impeller 36 is arranged.
  • the impeller 36 which is provided with vanes 52 and radial delivery channels 53, sucks in water axially via the suction openings 42 in the nozzle orifice 41 and feeds the suctioned water via the radial delivery channels 53 to the channel 49 in the nozzle orifice 41, which in the nozzle opening 50 directed towards the tub space ends.
  • the channel 49 starts from the wall of the pump chamber 51, which surrounds the impeller 36 on the circumference.
  • the nozzle orifice 41 can have a single channel 49 which ends in a single nozzle opening 50.
  • a plurality of channels 49 can also extend to different nozzle openings 50 ′ over the peripheral region of the pump chamber 51.
  • nozzle orifices 41 which are identical in their connecting dimensions to the housing ring 14 and in their design of the pump chamber 51.
  • the nozzle orifices 41 differ only in the arrangement of the channel 49 or the channels and the nozzle openings 50, 50 ′ and 50 ′′.
  • the suction openings 42 are always arranged centrally, so that the impeller 36 sucks in the water axially and forwards it radially.
  • the channel 49 or the channels start from the wall of the pump chamber 51 surrounding the impeller 36 and lead in the embodiment according to FIG.
  • the slit-shaped, circular-arc-shaped nozzle opening 50 3 ends a plurality of channels of the nozzle orifice 41 in the round nozzle openings 50 ', which lie on a circular path.
  • the cross section is relatively small, so that several round water jets emerge from the nozzle openings 50 '.
  • only a single round nozzle opening 50 ′′ is introduced in the nozzle orifice 41, which is preferably connected to the pump chamber 51 via a single channel 49 and, due to the large cross section, emits a strong water jet.
  • a circumferential ring channel 22 can be formed in the overlap area between the housing ring 14 and the motor mounting flange 23 if a groove is introduced in the circumference of the motor mounting flange 23 between the sealing rings 19 and 27.
  • the hose connection piece 20 is inserted radially, the through hole 21 of which opens into the annular channel 22.
  • Air ducts 25 of the motor mounting flange 23 are connected to air ducts 26 in the flange 29 of the housing ring 14, and these in turn connect to air ducts 44 and 46 of the nozzle orifice 41.
  • the air duct 46 feeds the air chamber 47 in the nozzle orifice 41.
  • ducts with a venturi opening 48 pass that are in the area of the nozzle openings 50, 50 'or 50' '. Due to the Venturi principle, the water jet flowing in the channel 49 or the channels sucks in air via the Venturi openings 48, which mixes with the water jet. A water jet mixed with air is therefore supplied to the tub space.
  • the air channels 25, 26 and 44 are closed at one end with sealing plugs 24, 30 and 45. The consequence of this is that they can easily be introduced as bores in the motor mounting flange 23, the flange 29 of the housing ring 14 and the nozzle orifice 41.
  • the impeller 36 sucks water axially out of the tub space and conveys this under pressure via the radial delivery channels 53 to the channel 49 in the nozzle orifice 41, which narrows towards the nozzle opening 50 in order to obtain an intensive water jet.
  • the annular channel 22 and the air channels 25, 26, 44 and 46 sucked-in air enters the air chamber 47, from which the channels forming the venturi openings 48 branch off. Due to the Venturi principle, the water jet or the water jets in the channel 49 or the channels of the nozzle orifice 41 suck air as it passes through the venturi openings 48 that mixes with the water jet or jets.
  • a hose is connected to the hose connector 20, the open end of which is above the maximum level of the water in the bathtub, so that when the pump is switched off via the venturi openings 48, the air channels 46, 44, 26 and 25 Ring channel 22 and the through hole 21 of the hose connector 20 no water can drain.
  • nozzle orifice 41 If the nozzle orifice 41 is removed, not only the impeller 36 of the pump can be removed, but the motor mounting flange 23 and the electric motor 18 connected to it can also be removed from the housing ring 14 and the housing pot 17 connected to it. All devices for generating the water and / or air jet are therefore easy to clean and easy to maintain or replace in the event of a fault. If the electric motor 18 is switched off, then no residual water remains in the device, since all the channels 49 and the air channels 25, 26, 44 and 46 empty themselves automatically.
  • the intensity of the water jet or jets of water can be regulated in a simple manner and the electric motors 18 of the facilities of the whirlpool bath can be controlled jointly and / or individually in order to be able to vary the operating mode of the whirl system.
