Die Erfindung betrifft eine Whirlpool-Badewanne mit Einrichtungen zum Erzeugen von Wasser- und/oder Luftstrah Len, die an mehreren Stellen der Wannenwand dem Wannenraum zuführbar sind, bei der jeder dieser Stellen eine indi iduelle, antreibbare Einrichtung zum Erzeugen eines Wasser- und/oder Luftst rah les zugeordnet ist, die in einen Durchbruch der Wannenwand eingebaut und von der Wannenaußenseite her mit Antriebsenergie beaufschlagbar ist, wobei jede Einrichtung ein Pumpengehäuse mit einer Pumpen-Kammer aufweist, in der ein Laufrad auf einer senkrecht zur Wannenwand stehenden, drehbar gelagerten Antriebswelle angeordnet ist, wobei die Pumpen-Kammer zum Wannenraum hin mit einer deckeiförmigen Düsenblende abgedeckt ist und das Laufrad über zentrische Ansaugöffnungen der Düsenblende axial Wasser aus dem Wannenraum ansaugt und über mindestens einen von der Pumpen-Kammer ausgehenden Kanal wieder dem Wannenraum zuführt, wobei der Kanal (bzw. die Kanäle) von dem das Laufrad umfangsei t g umschließenden Teil der Pumpen-Kammer ausgeht (bzw. ausgehen), und bei der das Laufrad von der axialen Ansaugöffnung ausgehende, radial gerichtete Förderkanäle aufweist.The invention relates to a whirlpool bath with facilities for generating water and / or air jet Len, which can be fed to the tub space at several points of the tub wall, in which each of these locations an indi idual, drivable device for generating a water and / or Luftst rah les is assigned, which is installed in an opening in the tub wall and can be acted upon from the outside of the tub with drive energy, each device having a pump housing with a pump chamber in which an impeller is arranged on a rotatably mounted drive shaft which is perpendicular to the tub wall the pump chamber is covered with a cover-shaped nozzle orifice towards the tub space and the impeller sucks water axially out of the tub space via central suction openings of the nozzle orifice and feeds it back to the tub space via at least one channel emanating from the pump chamber, the channel ( or the channels) from which the impeller surrounds gsei t g surrounding part of the pump chamber (or go out), and in which the impeller has radially directed delivery channels extending from the axial suction opening.
Eine Whirlpool-Badewanne dieser Art ist durch die DE-PS 38 12 519 bekannt. Dabei geht (gehen) der Kanal (bzw. die Kanäle) von der Pumpen-Kammer aus und sind in der Düsenblende angeordnet, die das Flügelrad umfangsseitig umschließt und einen Teil der Pumpen-Kammer bildet. In den Kanal der Düsenblende münden Luftkanäle des Pumpen-Gehäuses, um dem Wasserstrahl Luft beizumengen. Die Strahlöffnungen der Düsenblende sind daher stets an derselben Stelle, so daß der Strahl nicht verstellt und in anderer Richtung in den Wannenraum eingeführt werden kann. Darüber hinaus muß bei dem Einbau der Einrichtung in den Durchbruch der Badewanne darauf geachtet werden, daß das Pumpen-Gehäuse die richtige Position einnimmt, die für die gewünschte StrahLrichtung und den Anschluß der Düsenblende erforderlich ist.A whirlpool bath of this type is known from DE-PS 38 12 519. The channel ( or the Channels) from the pump chamber and are arranged in the nozzle orifice which surrounds the impeller on the circumference and forms part of the pump chamber. Air channels of the pump housing open into the channel of the nozzle orifice in order to add air to the water jet. The jet openings of the nozzle orifice are therefore always in the same place, so that the jet cannot be adjusted and introduced into the tub area in a different direction. In addition, when installing the device in the breakthrough of the bathtub, care must be taken that the pump housing is in the correct position, which is required for the desired jet direction and the connection of the nozzle orifice.
Um unterschiedliche Strahlbilder zu erhalten, ist es auch bekannt, bei Wh rIpool-Badewannen dieser Art Einrichtungen zu verwenden, bei denen untersch edliche Düsenblenden das Flügelrad der Pumpe umfangsseitig umschließen und mit unterschiedlichem Kanal (bzw. Kanälen) versehen sind, wie die DE-PS 38 00 400 zeigt. Dabei bleibt aber die Richtung des abgegebenen Strahles Cbzw. der abgegebenen Strahlen) gleich, da alle Düsenblenden in derselben vorgegebenen Position mit dem Pumpen-Gehäuse verbunden werden.In order to obtain different jet patterns, it is also known to use facilities in Wh rIpool baths of this type in which different nozzle orifices surround the impeller of the pump on the circumference and are provided with different channels (or channels), such as the DE-PS 38 00 400 shows. However, the direction of the emitted beam C or of the emitted jets) since all nozzle orifices are connected to the pump housing in the same predetermined position.
Es ist Aufgabe der Erfindung, bei einer Whirlpool-Badewanne der eingangs erwähnten Art die Einrichtungen so auszugestalten, daß der Einbau der Einrichtungen in die Durchbrüche der Badewanne erleichtert und vereinfacht wird und daß zusätzlich die Strahlaustrittsrichtung auf einfache Weise verändert werden kann.It is an object of the invention to design the devices in a whirlpool bath of the type mentioned at the outset in such a way that the installation of the devices in the breakthroughs of the bath is facilitated and simplified and that, in addition, the direction of the beam exit can be changed in a simple manner.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der den Kanal Cbzw. die Kanäle) aufweisende Teil der Pumpen-Kammer als getrenntes Verstellteil ausgebildet ist, das gegenüber einem in dem Durchbruch der Wannenwand unverdrehbar festgelegten Basis-Gehäuseteil des Pumpengehäuses zumindest begrenzt verdrehbar ist und daß der Kanal (bzw. die Kanäle) selbst eine Strahlaustrittsöffnung bzw. Strahlaustrittsöffnungen) bi ldet (bilden).This object is achieved according to the invention in that the channel Cbzw. the part of the pump chamber which has channels) is designed as a separate adjusting part, which can be rotated at least to a limited extent with respect to a base housing part of the pump housing which is fixed non-rotatably in the opening in the trough wall and that the channel (or the channels) itself forms (form) a jet outlet opening or jet outlet openings.
Der Einbau des Pumpen-Gehäuses mit der Pumpe ist jetzt unkritisch, da keine bestimmte Winkel-Position eingehalten werden muß. Das Verstelltei l als das Flügelrad umschließende Teil kann frei gedreht werden und da es den Kanal (bzw. die Kanäle) aufweist und selbst die Strahlöffnung (bzw. die Strahlöffnungen) bildet, ist eine einfache Veränderung der Strahlrichtung möglich.The installation of the pump housing with the pump is now uncritical, since no specific angular position has to be maintained. The adjustment part as the part enclosing the impeller can be rotated freely and since it has the channel (or channels) and even forms the jet opening (or jet openings), a simple change in the jet direction is possible.
Das Verstelltei l ist dabei zwischen dem Basis-Gehäusetei l des Pumpengehäuses und der Düsenblende, die jetzt nur noch die zentrische Ansaugöffnung aufweist.The adjustment part l is between the base housing part l of the pump housing and the nozzle orifice, which now only has the central suction opening.
Ist nach einer Ausgestaltung vorgesehen, daß die Pumpen-Kammer sich zum Wannenraum hin erweitert und daß der Kanal (bzw. die Kanäle) zum Wannenboden hin gerichtet ist (sind) und etwa parallel zur Wannenwand verläuft (verlaufen), dann kann sich die Einrichtung beim Ablassen des Wassers aus dem Wannenraum automatisch vollständig ent leeren .If it is provided according to an embodiment that the pump chamber extends towards the tub space and that the channel (or channels) is (are) directed towards the tub floor and runs approximately parallel to the tub wall, then the device can be located at Drain the water from the bathtub completely automatically.
Damit dies auch bei größerem Verstellbereich des Verstelltei ls der Fall ist, sieht eine weitere Ausgestaltung vor, daß die Drehbewegung des Verstelltei ls am Basis-Gehäusetei l so begrenzt ist, daß sich in den Endstellungen die Pumpen-Kammer über den Kanal (bzw. jeweils einen Kanal der Kanäle) vollständig zum Wannenraum hin entleeren kann.So that this is also the case with a larger adjustment range of the adjustment part, a further embodiment provides that the rotational movement of the adjustment part on the base housing part is limited so that in the end positions the pump chamber is located over the channel (or respectively a channel of the channels) can be completely emptied towards the tub area.
Die Verstellung des Verstellte ls wird nach einer Ausgestaltung dadurch erleichtert, daß das Verstellteil drehfest mit der Düsenblende, verbunden und mit dieser verdrehbar ist und daß die Düsenblende im Bereich der Strahlöffnung des Kanals (bzw. der Strahlöffnungen der Kanäle) ausgespart ist. Die Aussparung in der Düsenblende läßt einen ungehinderten Austritt des Strahles (bzw. der Strahlen) zu.The adjustment of the adjusted ls is facilitated according to one embodiment in that the adjustment part is rotatably connected to the nozzle orifice and rotatable therewith and in that the nozzle orifice is recessed in the region of the jet opening of the channel (or the jet openings of the channels). The recess in the nozzle orifice allows the jet (or jets) to exit unhindered.
Nach einer weiteren Ausgestaltung kann vorgesehen sein, daß das Verstellteil und die Düsenblende mit einer Abdeckung drehfest verbunden sind, die mit einem Lagerbund versehen ist, der mittels eines Befestigungsringes an einem im Durchbruch der Wannenwand festgelegten Aufnahmering frei drehbar gehalten ist und daß die Abdeckung im Bereich des Kanals Cbzw. der Kanäle) ausgespart ist. Die Verstellung des Verstellteils erfolgt dann mittels der Abdeckung. Ist dabei vorgesehen, daß die Abdeckung vor der zentrischen Ansaugöffnung der Düsenblende geschlossen und außerhalb dieses geschlossenen Bereiches mit radial gerichteten Schlitzen versehen ist, dann wird eine größere Sicherheit gegen Haareinzug erreicht.According to a further embodiment, it can be provided that the adjustment part and the nozzle screen are rotatably connected to a cover which is provided with a bearing collar which is held freely rotatably by means of a fastening ring on a receiving ring defined in the opening in the tub wall and that the cover is in the region of the channel C or of the channels) is left out. The adjustment part is then adjusted by means of the cover. If it is provided that the cover is closed in front of the central suction opening of the nozzle screen and is provided with radially directed slots outside this closed area, then greater security against hair intake is achieved.
Ist vorgesehen, daß zwischen dem Verstellteil und dem Basis-Gehäuseteil ein zusätzlicher Gehäusering angeordnet ist, der drehfest mit dem Verstellteil verbunden ist und sich über Dichtungsringe drehbar auf dem Aufnahmering abstützt und daß das Basis-Gehäuseteil in den Aufnahmering eingesetzt und mittels eines Schraubringes darin gehalten ist, sowie daß der Gehäuseπ'ng dem Aufnahmering zugekehrt eine Ringnut aufweist, die von den Dichtungsringen begrenzt ist, daß in die Ringnut eine an dem Aufnahmering angebrachte Luftzufuhr Leitung einmündet, und daß die Ringnut im Bereich der Kanäle in Aus laßδffnungen übergeht, dann kann dem abgegebenen Wasserstrahl (bzw. den abgegebenen Wasserstrahlen) Luft beigemengt werden.- Dabei kann über die Luftzufuh r Lei tung Druckluft eines Gebläses zugeführt werden oder die Auslaßöffnungen der Ringnut können als Venturiöffnungen ausgebi ldet sein. Im letzteren Fall muß die Ringnut nur mit der Atmosphäre in Verbindung stehen und zwar über dem höchsten Wasserstand in der Badewanne. Damit der Gehäusering mit dem Verstelltei l verstellt wird, ist vorgesehen, daß auch der Gehäusering drehfest mit dem Verstelltei l verbunden ist.It is provided that an additional housing ring is arranged between the adjustment part and the base housing part, which is non-rotatably connected to the adjustment part and is rotatably supported on the receiving ring via sealing rings and that the base housing part is inserted into the receiving ring and held therein by means of a screw ring is, and that the housing facing the receiving ring has an annular groove which is delimited by the sealing rings, that an air supply line attached to the receiving ring opens into the annular groove, and that the annular groove in the region of the channels changes into outlet openings, then the water jet (or the water jets) emitted can have air Compressed air from a blower can be supplied via the air supply line or the outlet openings of the annular groove can be configured as venturi openings. In the latter case, the ring groove only has to be in contact with the atmosphere and above the highest water level in the bathtub. So that the housing ring is adjusted with the adjusting part l, it is provided that the housing ring is also connected to the adjusting part l in a rotationally fixed manner.
Für die Drehlagerung des Verstelltei ls ist einfach vorgesehen, daß der Befestigungsring mit dem Aufnahmering verschraubt ist und den Lagerbund der Abdeckung übergreift, und daß sich der Lagerbund der Abdeckung an dem Aufnahmering abstützt und in der Aufnahme aus Befestigungsring und Aufnahmering frei drehbar ist. Da das Verstelltei l, der Gehäusering und die Düsenblende eine drehfeste Einheit bi lden, wird allein durch die Verdrehung der Abdeckung die Richtung des Strahles (bzw. der Strahlen) verändert. Die Aussparungen in der Abdeckung und der Düsenblende bleiben dabei dem Kanal (bzw. den Kanälen) des Verstelltei ls zugeordnet, so daß der Strahl (bzw. die Strahlen) ungehindert in den Wannenraum gelangen können.For the rotary bearing of the Verstelltei ls is simply provided that the mounting ring is screwed to the receiving ring and overlaps the bearing collar of the cover, and that the bearing collar of the cover is supported on the receiving ring and is freely rotatable in the receptacle from the fastening ring and the receiving ring. Since the adjustment part, the housing ring and the nozzle orifice form a non-rotatable unit, the direction of the jet (or jets) is changed simply by rotating the cover. The recesses in the cover and the nozzle orifice remain assigned to the channel (s) of the adjustment part so that the jet (or jets) can enter the tub space unhindered.
Die drehfeste Einheit wird einfach dadurch erhalten, daß die Abdeckung mit einem Innengewinde auf einem Außengewinde des Gehäuseringes verschraubt ist und daß die Abdeckung und der Gehäusering eine Aufnahme bi lden, in der die Düsenblende und das Verstelltei l verspannt und unverdrehbar gehalten sind. Damit die Einheit aus Abdeckung, Düsenblende, Verstellteil und Gehäusering zum Reinigen leicht abgenommen werden kann, ist vorgesehen, daß der Gehäusering eine Innenaufnahme aufweist, deren Durchmesser größer ist als der Außendurchmesser des Laufrades.The non-rotatable unit is obtained simply by screwing the cover with an internal thread onto an external thread of the housing ring, and in that the cover and the housing ring form a receptacle in which the nozzle screen and the adjusting part 1 are clamped and held in a non-rotatable manner. So that the unit consisting of cover, nozzle orifice, adjustment part and housing ring can be easily removed for cleaning, it is provided that the housing ring has an inner receptacle whose diameter is larger than the outer diameter of the impeller.
Die Erfindung wird anhand einer in der Zeichnung im Schnitt dargestellten Einrichtung zum Einbau in einen Durchbruch einer Badewanne näher erläutert.The invention is explained in more detail with reference to a device for installation in an opening in a bathtub shown in the drawing.
Von de r Badewanne, in die mehrere derartige Einrichtungen eingebaut werden, ist ein Teil einer Wannenwand 1 gezeigt, die einen Durchbruch 22 aufweist. In diesen Durchbruch 22 ist ein im Querschnitt U-förmiger Dichtungsring 14 eingesetzt, der auf beiden Seiten der Wannenwand 1 den Rand des Durchbruches 22 überdeckt. Vom Wannenraum aus (von links) wird in den Durchbruch 22 ein Aufnahmering 28 eingesetzt, der mit einem nicht näher bezeichneten Befestigungsflansch den Dichtungsr ng 14 übergreift und mit einem nicht näher bezeichneten hülsenförmigen Ansatz mit Außengewinde durch den Durchbruch 22 ragt. Auf diesen Ansatz des Aufnahmeringes 28 wird eine Scheibe 21 aufgeschoben, die sich an dem Dichtungsring 14 abstützt und mit einer Mutter 20, die auf das Außengewinde des Ansatzes aufgeschraubt wird, gegen den Dichtungsring 14 verspannt wird. Damit ist der Aufnahmering 28 dicht in dem Durchbruch 22 der Wannenwand 1 festgelegt. An der Mutter 20 kann ein Motortopf 16 befestigt sein, der" eine Abdeckung für einen Pumpenmotor 17 bildet. Dieser Pumpenmotor 17 ist mit seiner Antriebswelle in einem Basis-Gehäuseteil 23 einer Pumpen-Kammer P gelagert. Die Antriebswelle ist in Gleitringdi chtungen 9 drehbar, die mittels D chtungsringen zu der Antriebswelle und zum Bas s-Gehäusetei l 23 abgedichtet sind. Das Basis-Gehäuseteil 23 stützt sich mit einem Bund auf einem Absatz des Aufnahmeringes 28 ab und wird mittels eines Schraubringes 10 in diesem festgelegt. Ein Dichtungsring 11 dichtet dabei den umfangssei ti gen Übergang vom Basi s-Gehäsuetei l 23 zum Aufnahmering 28. Mit einer Hutmutter 7 und einer Befestigungshülse 8 ist auf der Antriebswelle des Pumpenmotors 17 ein Laufrad 6 drehfest aufgebracht. Dieses Laufrad 6 hat eine zentrische Ansaugöffnung und anschließende, radial ausgerichtete Förderkanä le . Auf der Vorderseite des Aufnahmeri nges 28 stützt sich ein Gehäusering 3 ab. Auf der dem Aufnahmering 28 zugekehrten Seite des Gehäuseringes 3 ist eine Ringnut 29 eingebracht, die von zwei Dichtungsringen 12 und 13 umschlossen und abgedichtet wird. Der Aufnahmering 28 hat einen Anschluß für eine Luftzufuhrleitung 15, der in die Ringnut 29 des GehäuseringesA part of a tub wall 1, which has an opening 22, is shown of the bathtub, in which several such devices are installed. In this opening 22 a cross-sectionally U-shaped sealing ring 14 is inserted, which covers the edge of the opening 22 on both sides of the tub wall 1. From the tub space (from the left), a receiving ring 28 is inserted into the opening 22, which overlaps the sealing ring 14 with a fastening flange (not shown) and projects through the opening 22 with a sleeve-shaped extension (not shown) with an external thread. On this approach of the receiving ring 28, a washer 21 is pushed, which is supported on the sealing ring 14 and is clamped against the sealing ring 14 with a nut 20 which is screwed onto the external thread of the approach. So that the receiving ring 28 is tightly fixed in the opening 22 of the tub wall 1. A motor pot 16, which "forms a cover for a pump motor 17, can be fastened to the nut 20. This pump motor 17 is mounted with its drive shaft in a base housing part 23 of a pump chamber P. The drive shaft can be rotated in mechanical seals 9, which are sealed by means of sealing rings to the drive shaft and to the base housing part 23. The base housing part 23 is supported with a collar on a shoulder of the receiving ring 28 and is fixed therein by means of a screw ring 10. A sealing ring 11 seals the circumferential side transition from the base housing 23 to the receiving ring 28. With a cap nut 7 and a fastening sleeve 8, an impeller 6 is rotatably mounted on the drive shaft of the pump motor 17. This impeller 6 has a central suction opening and subsequent, radially aligned Förderkanä le. On the front of the Aufnahmeri nges 28, a housing ring 3 is supported. On the side of the housing ring 3 facing the receiving ring 28, an annular groove 29 is introduced, which is enclosed and sealed by two sealing rings 12 and 13. The receiving ring 28 has a connection for an air supply line 15, which is in the annular groove 29 of the housing ring
3 einmündet. Dabei spielt die Winkelstellung des Aufnahmeri nges 28 zum Gehäusering 3 keine Rolle, der Anschluß der Luftzufuhr lei tung 15 mündet stets in die Ringnut 29 des Gehäuseringes . 3. Der Befestigungsflansch des Aufnahmeringes 28 weist ein Außengewinde auf, auf das ein Befestigungsring 2 mit Innengewinde aufgeschraubt werden kann. Dieser Befesti gungs ri ng 2 umschließt einen Lagerbund 27 einer Abdeckung 25 und bildet mit dem Aufnahmering 2 eine Aufnahme, in der der Lagerbund 27 der Abdeckung 25 frei drehbar ist. Die Abdeckung 28 ist mit einem Innengewinde auf ein Außengewinde des Gehäuseringes 3 aufgeschraubt. Die Abdeckung 28 und der Gehäusering 3 bi lden eine ringförmige Aufnahme für ein Verstellteil 4 und eine Düsenblende 5. Die Düsenblende 5 und das Verstelltei l 4 vervollständigen die Pumpen-Kammer P, die motorseitig durch den Gehäusering 3, den Schraubring 10 und das Basis-Gehäuseteil 23 abgeschlossen ist. Das Verstelltei l3 flows into. The angular position of the Aufnahmeri nges 28 to the housing ring 3 does not matter, the connection of the air supply line 15 always opens into the annular groove 29 of the housing ring. 3. The mounting flange of the receiving ring 28 has an external thread onto which a mounting ring 2 with an internal thread can be screwed. This fastening supply ring 2 encloses a bearing collar 27 of a cover 25 and forms with the receiving ring 2 a receptacle in which the bearing collar 27 of the cover 25 is freely rotatable. The cover 28 is screwed onto an external thread of the housing ring 3 with an internal thread. The cover 28 and the housing ring 3 form an annular receptacle for an adjustment part 4 and a nozzle orifice 5. The nozzle orifice 5 and the adjustment part 4 complete the pump chamber P, which is motor-side through the housing ring 3, the screw ring 10 and the base Housing part 23 is completed. The adjusting part l
4 und die Düsenblende 5 werden zwischen der Abdeckung 25 und dem Gehäusering 3 verspannt, wenn die Abdeckung 25 auf den Gehäusering 3 aufgeschraubt wird. Damit bilden die4 and the nozzle orifice 5 are between the cover 25 and the housing ring 3 clamped when the cover 25 is screwed onto the housing ring 3. With that form the
Abdeckung 25, die -Düsenblende 5, das Verstellteil 4 und der Gehäusering 3 eine feste Einheit, die in der von demCover 25, the nozzle orifice 5, the adjustment part 4 and the housing ring 3 is a fixed unit, which in the by
Befestigungsring 2 und dem Aufnahmering 28 gebildeten und den Lagerbund 27 der Abdeckung . 5 aufnehmenden, ringförmigen Aufnahme frei drehbar ist.Fastening ring 2 and the receiving ring 28 formed and the bearing collar 27 of the cover. 5 receiving, annular recording is freely rotatable.
Das Verstellteil 4 umschließt das Flügelrad 6 umfangsseitig und weist einen oder mehrere radial gerichtete Kanäle K auf, die selbst als Strahlöffnung enden. Im Bereich dieser Strahlöffnungen sind die Düsenblende 5 und die Abdeckung 25 ausgespart, so daß die Strahlen ungehindert in den Wannenraum gelangen können. Durch Verdrehen der Abdeckung 25 wird die Einheit aus Düsenblende 5, Verstellteil 4 und Gehäusering 3 verstellt, so daß sich die Richtung der abgegebenen Strahlen verändert. Im Prinzip kann die Einheit um 360° frei in beiden Richtungen verdreht werden. Soll sich die Einrichtung, d.h. die Pumpen-Kammer P, stets vollständig entleeren können, dann muß die Verdrehung der Einheit so begrenzt werden, daß in den Endstellungen der Einheit die Entleerung noch über einen nach unten gerichteten Kanal K möglich ist. Die Kanäle K sind dabei über einen entsprechenden Umfangsberei ch des Verstellteils 4 verteilt angeordnet.The adjustment part 4 surrounds the impeller 6 on the circumference and has one or more radially directed channels K, which themselves end as a jet opening. In the area of these jet openings, the nozzle orifice 5 and the cover 25 are cut out, so that the jets can reach the tub space unhindered. By turning the cover 25, the unit consisting of the nozzle screen 5, the adjustment part 4 and the housing ring 3 is adjusted so that the direction of the emitted jets changes. In principle, the unit can be freely rotated through 360 ° in both directions. Should the facility, i.e. the pump chamber P, can always completely drain, then the rotation of the unit must be limited so that in the end positions of the unit emptying is still possible via a downward channel K. The channels K are distributed over a corresponding circumferential area ch of the adjusting part 4.
Die Ringnut 29 des Gehäuseringes 3 geht im Bereich der Kanäle K in Auslaßöffnungen 30 über, so daß den abgegebenen Wasserstrahlen Luft beigemengt werden kann. Diese Luft kann als Druckluft eines Gebläses über die Luftzufuhrleitung 15 zugeführt werden. Es ist auch möglich, die Auslaßöffnungen 30 als Venturiöffnungen auszubilden. Dann stellt die Luf zufuhrLe tung 15 nur die Verbindung zur Atmosphäre her und dies über dem maximalen Wasserstand der Badewanne, um ein Abfließen von Wasser über diesen Weg zu vermeiden.The annular groove 29 of the housing ring 3 merges into outlet openings 30 in the region of the channels K, so that air can be added to the water jets emitted. This air can be supplied as compressed air from a blower via the air supply line 15. It is also possible to design the outlet openings 30 as venturi openings. Then the air supply line 15 only provides the connection Atmosphere and this above the maximum water level of the bathtub in order to prevent water from flowing off in this way.
Die Abdeckung 25 deckt mit einem geschlossenen, zentrischen Bereich die zentrische Ansaugöffnung 24 der Düsenblende 5 und des Laufrades 6 ab und hat von diesem Bereich ausgehende, radial gerichtete Schlitze 26. Damit wird ein Einziehen von Haaren des Benutzers verhindert und ein geforderter Haarfangtest erfüllt.The cover 25 covers the central suction opening 24 of the nozzle orifice 5 and the impeller 6 with a closed, central area and has radially directed slots 26 extending from this area. This prevents the hair from being drawn in by the user and fulfills a required hair catch test.
Der Pumpenmotor 17 wird über ein Versorgungskabel 19 mit elektrischer Antriebsenergie versorgt, das mittels einer Kabeldurchführung 18 in den Motortopf 16 eingeführt und mit dem Pumpenmotor 17 verbunden ist.The pump motor 17 is supplied with electrical drive energy via a supply cable 19 which is introduced into the motor pot 16 by means of a cable bushing 18 and is connected to the pump motor 17.
Mit dem Lösen des Befest i gungs ri nges 2 kann die Einheit aus Düsenblende 5, Verstelltei l 4 und Gehäusering 3 abgenommen und gereinigt werden. Dabei ist wichtig, daß der Gehäusering 3 eine Innenaufnahme hat, deren Durchmesser etwas größer ist als der Außendurchmesser des Laufrades 6. Mit dem Lösen des Schraubringes 10 kann auch die Pumpe mit Pumpenmotor 17, Laufrad 6 und Basis-Gehäusetei l 23 leicht ausgewechselt werden. When the fastening ring 2 is loosened, the unit consisting of the nozzle screen 5, the adjusting part 4 and the housing ring 3 can be removed and cleaned. It is important that the housing ring 3 has an inner receptacle whose diameter is slightly larger than the outer diameter of the impeller 6. With the loosening of the screw ring 10, the pump with pump motor 17, impeller 6 and basic housing part 23 can be easily replaced.
