Whi rIpooL-BadewanneWhi rIpooL bathtub
Die Erfindung betrifft eine Wh i r Ipoo l-Badewanne mit einer oder mehreren Ansaugvorrichtungen zum ^Ansaugen, Fördern und Zuleiten von Wasser aus oder in den Wannenraum, wobei das Wasser an einer oder mehreren Stellen der Badewanne über eine mit Ansaugöffnungen versehenen Ansaugblenden ansaugbar und an mehreren Stellen über mit Austrittsöffnungen versehenen Düsen bzw. über die mit Austrittsöffnungen versehenen Ansaugblenden selbst dem Wannenraum wieder zuführbar ist.The invention relates to a Wh ir Ipoo l bathtub with one or more suction devices for ^ sucking, conveying and supplying water from or into the tub space, the water being able to be sucked in at one or more points of the bathtub via a suction panel provided with suction openings and in several Can be supplied to the tub space again via nozzles provided with outlet openings or via the suction panels provided with outlet openings.
Es sind Whi r Ipoo l-Badewannen mit einer einzigen Ansaugstelle bekannt, die mittels einer Ansaugblende mit Ansaugöffnungen abgedeckt ist. Eine zentrale Ansaugvorrichtung saugt das Wasser aus dem Wannenraum an und führt es mehreren, mit Austrittsöffnungen versehenen Düsen und darüber wieder dem Wannenraum zu. Die zentrale Ansaugstelle ist einer leistungsstarken Ansaugvorrichtung zugeordnet, um ausreichend viel Wasser anzusaugen. Dabei besteht die Gefahr, daß Haare von badenden Personen eingesaugt werden, die sich hinter derThere are Whi r Ipoo l bathtubs with a single suction point, which is covered by means of a suction panel with suction openings. A central suction device sucks the water out of the tub area and feeds it to several nozzles with outlet openings and then back to the tub area. The central suction point is assigned to a powerful suction device in order to draw in sufficient water. There is a risk that hair will be sucked in by bathing people who are behind the

Es sind daher schon Ansaugblenden vorgeschlagen worden, die sich mit einer vorgegebenen Zugkraft lösen lassen, um die Gefahr des Festhaltens einer badenden Person zu verhindern. Diese konstruktive Lösung ist jedoch sehr aufwendig und nicht absolut bet riebssicher.Intake screens have therefore already been proposed which can be released with a predetermined tensile force in order to prevent the danger of a bathing person being held on. However, this constructive solution is very complex and not absolutely reliable.
Eine Whi r Ipoo l-Badewanne mit mehreren Ansaugblenden ist aus der DE 39 07 552 C1 bekannt. Bei dieser bekannten Whi r Ipoo l-Badewanne sind individuelle Ansaugvorrichtungen mit Laufrädern vorgesehen, die von Elektromotoren angetrieben werden und unmittelbar hinter der Ansaugblende angeordnet sind. Durch die Ansaugöffnungen der Ansaugblende wird von dem Laufrad radial Wasser aus dem Wannenraum angesaugt.A Whi r Ipoo l bath with several intake panels is known from DE 39 07 552 C1. In this known Whi r Ipoo l bath individual suction devices with impellers are provided which are driven by electric motors and are arranged directly behind the suction panel. Water is drawn radially from the tub space by the impeller through the suction openings of the suction panel.
Bei solchen Wh i r Lpoo L-Badewannen besteht die Gefahr, daß Haare einer badenden Person in die Ansaugöffnung eingesaugt werden, die sich dann um eine, das Laufrad antreibende Welle oder um das Laufrad selbst schlingen oder sich hinter der Ansaugblende verknoten. Die badende Person kann dadurch unter Wasser gehalten werden, so daß sie erstickt.With such Wh i r Lpoo L bathtubs there is a risk that hair of a bathing person will be sucked into the suction opening, which will then loop around a shaft that drives the impeller or around the impeller itself or become knotted behind the suction panel. The bathing person can be kept under water so that they suffocate.
Es ist Aufgabe der Erfindung, bei Whi r lpoo l-Badewannen der eingangs erwähnten Art ein Festhalten von Haaren an einer Ansaugblende mit einfachen Mitteln zu verhindern.It is an object of the invention to prevent hair from sticking to a suction panel in Whi r lpoo l bathtubs of the type mentioned at the outset by simple means.
Die Aufgabe wird dadurch gelöst, daß in St rö ungs r i chtung des angesaugten Wassers hinter der oder den Ansaugblenden und zu diesen beabstandet jewei ls ein Schutzsieb angeordnet ist, das mit einer Vielzahl von Durchbrüchen versehen ist, deren Öffnungsweiten so klein sind, daß ein Einsaugen von Haaren in das Schutzsieb verhindert ist. Mittels des Schutzsiebes verwirbelt das Wasser zwischen der Ansaugblende und dem Schutzsieb. In dieser Ve rwi rbe lungszone ist der Ansaugströmung eine Querströmung überlagert. Versuche der Anmelderin mit Unterwasserkameras haben gezeigt, daß evtl. durch die Ansaugblende eingesogene Haarspitzen von den Querströmungen ungerichtet bewegt werden, so daß sie sich nicht verknoten können und auch nicht von der Ansaugströmung durch die Durchbrüche des Schutzsiebes eingesogen werden. Damit die Haarspitzen sicher nicht in das Schutzsieb eingesogen werden, ist vorgesehen, daß die Durchbrüche des Schutzsiebes als Bohrungen ausgebi ldet sind, die maximal einen Durchmesser von 1,5 mm auf eisen.The object is achieved in that a protective sieve is arranged in the flow direction of the sucked-in water behind the or the suction orifices and at a distance therefrom, which is provided with a multiplicity of openings, the opening widths of which are so small that suction is prevented by hair in the protective sieve. The water swirls between the suction panel and the protective screen by means of the protective screen. In this processing zone, a cross-flow is superimposed on the intake flow. Attempts by the applicant with underwater cameras have shown that hair tips possibly sucked in through the suction panel are moved in a non-directional manner by the cross currents, so that they cannot knot and are not sucked in by the suction flow through the openings in the protective screen. So that the hair tips are certainly not sucked into the protective screen, it is provided that the openings of the protective screen are formed as bores which have a maximum diameter of 1.5 mm on iron.
Um sicherzustellen, daß in Regionen mit kalkhaltigem Wasser trotz der Zusetzung der Bohrungen mit Kalk noch eine ausreichende Menge an Wasser angesaugt wird, ist vorgesehen, daß das Schutzsieb zusätzlich. als Schlitze ausgebildete Durchbrüche aufweist, deren Breite höchstens 1,5 mm betragen.In order to ensure that a sufficient amount of water is still sucked in regions with calcareous water despite the addition of the boreholes with lime, it is provided that the protective sieve is additionally. has openings formed as slots, the width of which is at most 1.5 mm.
Die Breite der Schlitze darf höchstens 1,5 mm betragen, um ein Einsaugen von Haaren sicher zu verhindern. Ist die Ausgestaltung so vorgenommen, daß sich die Ansaugblende mit einem Bund auf einem Ring abstützt, daß der Ring einen Absatz aufweist, auf dem sich Ansätze des Schutzsiebes so abstützen, daß die Ansaugblende von dem Schutzsieb beabstandet ist, und daß Andrückmittel vorgesehen sind, die das Schutzsieb an dem Ring halten, dann lassen sich die Ansaugblende und das Schutzsieb einfach montieren. Der Absatz gewährleistet, daß das Schutzsieb stets beabstandet zur Ansaugblende gehalten und damit die Ausbi ldung der Ve rwi rbe lungszone zwischen Ansaugblende und Schutzsieb gewährleistet ist. Der Abstand zwischen dem Schutzsieb und der Ansaugblende darf maximal 1,5 mm bet ragen . Eine Ausgestaltung einer Wh i r lpoo l-Badewanne sieht vor, daß das Andrück ittel als Strahlführung ausgebi ldet ist, dann läßt sich der Tei leaufwand reduzieren. Die Befestigung der St rah l füh rung ist beispielsweise dadurch erreichbar, daß sie mit einem Gewinde in eine Gewindeaufnahme der Ansaugblende eingeschraubt ist oder daß sie Schraubenaufnahmen aufweist, in die Schrauben einführbar und an einer Halterung des Motors einschraubbar sind.The width of the slots must not exceed 1.5 mm in order to prevent hair from being sucked in. Is the design made so that the suction panel is supported with a collar on a ring, that the ring has a shoulder on which approaches of the protective screen are supported so that the suction panel is spaced from the protective screen, and that pressure means are provided that hold the protective screen on the ring, then the suction panel and the protective screen can be easily installed. The paragraph ensures that the protective screen is always kept at a distance from the intake panel and thus the training of the processing zone between the intake panel and protective screen is ensured. The distance between the protective screen and the intake panel may not exceed 1.5 mm. An embodiment of a wh irpoo l bathtub provides that the pressing means is designed as a beam guide, then the part effort can be reduced. The fastening of the steel guide can be achieved, for example, by screwing it with a thread into a thread receptacle of the intake panel or by having screw receptacles into which the screws can be inserted and screwed onto a mounting of the motor.
Bei kreis-, rosetten- oder ringförmigen Schutzsieben ist für eine gleichmäßige Wasserzufuhr vorgesehen, daß vier Schlitze vi erte l k rei sför i g in Umfangs ri chtung in das Schutzsieb eingebracht sind, wobei die Breite der Schlitze maximal 1,5 mm bet ragt .In the case of circular, rosette- or ring-shaped protective screens, it is provided for a uniform water supply that four slots are inserted into the protective screen in circumferential direction, the width of the slots being a maximum of 1.5 mm.
Die Schlitze können beispielsweise auf dem mittleren Tei l k rei sdurch esse r angeordnet sind. Ist das Schutzsieb als Stanz-Bi egetei l ausgestaltet, so können die Schlitze leicht aus dem Blechzuschnitt ausgestanzt sein.The slots can, for example, be arranged on the middle part of the rice diameters. If the protective screen is designed as a punched bowing component, the slots can easily be punched out of the sheet metal blank.
Eine Ausgestaltung mit mehreren Ansaugblenden, denen individuelle Ansaugvorrichtungen zugeordnet sind, ist dadurch gekennzeichnet, daß jede Ansaugvorrichtung ein elektromotorisch angetriebenes Laufrad aufweist, das unmittelbar hinter dem Schutzsieb in einer Pumpenkammer untergebracht ist, und daß die Ansaugblende und das Schutzsieb ringförmige Bleche sind, die tulpenartig ausgestülpt sind, so daß sie h i nte rei nande r l i egend das Laufrad zum Wannenraum hin abdecken.An embodiment with several intake panels, to which individual intake devices are assigned, is characterized in that each intake device has an electric motor-driven impeller, which is accommodated directly behind the protective screen in a pump chamber, and in that the intake screen and the protective screen are ring-shaped sheets that are tulip-like are so that they cover the impeller towards the tub area.
Nach einer vortei lhaften Ausgestaltung ist vorgesehen, daß das Schutzsieb eine andere geometrische Form aufweist als dieAccording to a advantageous embodiment, it is provided that the protective screen has a different geometric shape than that
Ansaugblende, so daß zwischen der Ansaugblende und demIntake panel so that between the intake panel and the
Schutzsieb zwangsweise ein Zwischenraum gebildet ist, der die Ve rwi rbe lungszone bi ldet. Damit läßt sich der Montageaufwand erheblich reduzieren.Protective sieve is forcibly formed a space that the Processing zone is shown. This significantly reduces the assembly effort.
Für die Rückführung des Wassers in den Wannenraum ist vorgesehen, daß die Ansaugblende und das Schutzsieb je eine zentrische, die Austrittsöffnung bi ldende Ausnehmung aufweist, daß die Ansaugblende einen Bund aufweist, auf dem sich die Strahlführung mit einem Flansch abstützt und daß die Strahlführung mit einem Befest i gungsri ng an der Ansaugblende befestigbar ist.For the return of the water into the tub space, it is provided that the suction panel and the protective screen each have a central recess forming the outlet opening, that the intake panel has a collar on which the jet guide is supported with a flange and that the jet guide with a Fastening ring is attachable to the intake panel.

Der Elektromotor 60 treibt mit seiner Antriebswelle ein als Flügelrad ausgebi ldetes Laufrad 63 an. Das Laufrad 63 ist durch ein Motorschi ld 61 abgedeckt. Auf der Stirnseite des Bundes 62 ist ein Ring 50 festlegbar. Der Ring 50 weist einen umlaufenden Absatz 51 auf, auf dem sich ein Schutzsieb 10 mit seinen Ansätzen 11 abstützt. Die Ansätze 11 sind um 90° zueinander versetzt auf dem Umfang des Schutzsiebes 10 angeordnet . Das Schutzsieb 10 ist im wesentlichen rosettenförmi g ausgebi ldet und weist eine zentrisch angeordnete Austrittsöffnung 14 auf. Fluchtend zu dieser Austrittsöffnung 14 ist in einer Ansaugblende 20 eine weitere Austrittsöffnung 24 eingebracht. Die Ansaugblende 20 ist ebenfalls rosettenfö rm g ausgebi ldet und weist als Ansaugöffnungen radial verlaufende Schlitze 21 auf. An der dem Elektromotor 60 zugekehrten Seite der Ansaugblende 20 ist ein Bund 22 angeordnet, der sich auf dem Ring 50 abstützt.In Fig. 1 an electric motor 60 is shown, which has a sti rnsei ti gene collar 62. The collar 62 serves to receive the electric motor 60 in a tub wall of a whirlpool bathtub, which is not shown in this figure. The electric motor 60 drives an impeller 63 designed as an impeller with its drive shaft. The impeller 63 is covered by a motor part 61. A ring 50 can be fixed on the end face of the collar 62. The ring 50 has a circumferential shoulder 51, on which a protective screen 10 with its lugs 11 is supported. The lugs 11 are arranged offset by 90 ° to one another on the circumference of the protective screen 10. The protective screen 10 is formed essentially in the shape of a rosette and has a centrally arranged outlet opening 14. In alignment with this outlet opening 14, a further outlet opening 24 is introduced in a suction panel 20. The intake panel 20 is also formed in a rosette shape and has radially extending slots 21 as intake openings. A collar 22, which is supported on the ring 50, is arranged on the side of the intake panel 20 facing the electric motor 60.
Damit ist die Ansaugblende 20 zum Schutzsieb 10 beabstandet auf dem Ring 50 festlegbar, so daß zwischen der Ansaugblende 20 und dem Schutzsieb 10 eine Ve rwi rbe lungszone geschaffen ist. Frontseitig ist im Bereich der Austrittsöffnung 24 an der Ansaugblende 20 ein umlaufender Absatz 23 angeordnet, so daß eine Strahlführung 30, die sich mit einem Flansch 31 auf dem Absatz 23 abstützt, in di e „ Aust ri ttsöffnung 24 einsetzbar ist. In die Strahlführung 30 sind bogenförmige Schlitze 33 eingebracht, die zur Bündelung des austretenden Wasserstrahls dienen. An seiner Rückseite weist die Stra lführung 30 ein als Bund ausgebi ldetes Andrückmittel 32 auf, mit dem die Ansätze 11 des Schutzsiebes 10 auf dem Absatz 51 des Ringes 50 gedrückt und somit gesichert gehalten werden. In dem Flansch 31 sind drei, um 120° versetzte Zent ri e rst i fte 34 eingebracht. Fluchtend zu diesen Zent ri erst i ften 34 sind in einem Befest i gungsri ng 40 die entsprechenden Zentrierbohrungen 44 eingebracht, so daß der Befestigungsπ'ng 40 mit der Strahlführung 30 mittle eines Gewindes 45 in eine Ge indeaufnahme des Motorschi ldes 61 geschraubt werden kann. Die Bohrungen 41 im Befest i gungsri ng 40 dienen zur Zentrierung eines Montageschlüssels.So that the intake panel 20 is spaced from the protective screen 10 on the ring 50, so that between the intake panel 20 and the protective screen 10 a Ve rwi rbe treatment zone is created. A circumferential shoulder 23 is arranged on the intake panel 20 in the area of the outlet opening 24 so that a beam guide 30, which is supported on the shoulder 23 with a flange 31, can be inserted into the outlet opening 24. Arc-shaped slots 33 are made in the beam guide 30, which are used to concentrate the emerging water jet. On its rear side, the road guide 30 has a pressure means 32 designed as a collar, with which the lugs 11 of the protective screen 10 are pressed onto the shoulder 51 of the ring 50 and are thus held securely. In the flange 31 three center slots 34 are inserted, offset by 120 °. In alignment with these centering ri only i ften 34 ng in a Befest i gungsri 40 the corresponding centering bores introduced 44 so that the Befestigungsπ ng '40 with the beam guide 30 45 mittle a thread in a Ge indeaufnahme the motor ski L of can be screwed 61st The holes 41 in the fastening ring 40 serve to center a mounting key.

Dringen Haarspitzen durch die Schlitze 21 der Ansaugblende 20 ein, so gelangen diese aufgrund der in der Verwi rbe lungszone herrschenden Querst römungen nicht in die Durchbrüche 13 des Schutzsiebes 10. Mit einem s lchen zusätzlichen Schutzsieb 10 kann nicht nur die Gefahr des Festhaltens der badenden Personen ausgeschlossen werden, sondern es ist noch zusätzlich erreicht, daß im Wasser schwimmende Lose Haare oder Gewebefasern vom Laufrad 63 nicht angesaugt werden. Diese könnten, wenn sie sich um die Antriebswelle oder um das Laufrad 63 wickeln, sonst eine Beeinträchtigung der Funktionsfähigkeit und der Lebensdauer des Elektromotors 60 bewirken. Penetrate hair through the slots 21 of the suction panel 20, they do not get into the breakthroughs 13 of the protective screen 10 due to the prevailing cross-currents in the administrative zone. With a small additional protective screen 10, not only can the risk of holding the bathing person in place can be excluded, but it is additionally achieved that loose hair or fabric fibers floating in the water are not sucked in by the impeller 63. If they wind around the drive shaft or around the impeller 63, these could otherwise impair the functionality and the service life of the electric motor 60.
