HandbrauseHand shower
Technisches GebietTechnical field
Die Erfindung betrifft eine Handbrause, insbesondere zur Reinigung von Haaren, bei der das flüssige Reinigungsmittel, z. B. Wasser, aus den Düsen im Brausenkopf der Handbrause mit relativ großer Geschwindigkeit austritt.The invention relates to a hand shower, especially for cleaning hair, in which the liquid cleaning agent, for. B. water, emerges from the nozzles in the shower head of the hand shower at a relatively high speed.
Stand der TechnikState of the art
Handbrausen sind nach dem Stand der Technik mit verschie- dener Düsengestaltung bekannt .Hand showers are known in the prior art with various nozzle designs.
Die DE 37 06 320 AI gibt beispielsweise einen Brausenkopf an, der für das wahlweise Abgeben von Wasserstrahlen verschiedener Art vorgesehen ist . Der Brausenkopf weist eine Mehrzahl von paketartig in konzentrischer und zuein- ander koaxialer Anordnung zusammengefaßten ringzylindrischen Steuerungselementen auf, die miteinander eine Vielzahl von Durchlaßsöffnungen für die Abgabe von ebensovie- len Wasserstrahlen definieren und begrenzen, und mindestens eines dieser Steuerungselemente von Hand um die gemeinsame Mittelachse der Gesamtanordnung von Steuerungs- elementen verdreht werden kann, um das durch eine Zufuhröffnung hindurch ankommende Wasser je nach der gewünschten Strahlform in Richtung auf mindestens eine der Durchlaßöffnungen umzulenken.DE 37 06 320 AI specifies, for example, a shower head which is provided for the optional delivery of water jets of various types. The shower head has a plurality of ring-cylindrical control elements which are combined in a packet-like manner in concentric and coaxial arrangement and which together define and limit a plurality of passage openings for the delivery of just as many water jets, and at least one of these control elements by hand around the common central axis of the Overall arrangement of control elements can be rotated in order to divert the water arriving through a supply opening, depending on the desired jet shape, in the direction of at least one of the through openings.
Die DE 40 33 364 AI gibt eine Handbrause mit integriertem Unterbrecher und variablem Duschstrahl an. Dabei weist der Bereich der Wasseraustrittsöffnungen im Kopfteil eine rechteckige Grundfläche auf . Mit einem Steuerteil im Kopfteil können die Austrittsoffnungen unterschiedlich weit geöffnet oder geschlossen werden.DE 40 33 364 AI specifies a hand shower with an integrated interrupter and variable shower jet. The area of the water outlet openings in the head part has one rectangular base. With a control part in the head part, the outlet openings can be opened or closed to different degrees.
Im wesentlichen weisen nach dem Stand der Technik alle Brauseköpfe konzentrische und flächig angeordnete Austrittsoffnungen auf, wobei die Gesamtfläche, in der die Austrittsoffnungen angeordnet sind, mehr oder weniger groß ist . In vielen Fällen kann zwischen einem sehr weichen Strahl und kreisförmig angeordneten Austrittsoffnungen für einen härteren Strahl gewählt werden. Der flächige Charakter des Wasserauslasses bleibt auch bei der letzteren Gestaltung erhalten.Essentially, according to the prior art, all shower heads have concentric and flat outlet openings, the total area in which the outlet openings are arranged being more or less large. In many cases it is possible to choose between a very soft jet and circular exit openings for a harder jet. The flat character of the water outlet is also retained in the latter design.
Nachteilig bei den Lösungen des Standes der Technik ist, daß der Wasserverbrauch bei fast allen Brausen auch bei Verwendung von Wasserstopeinrichtungen relativ hoch ist.A disadvantage of the solutions of the prior art is that the water consumption in almost all showers is relatively high even when using water stop devices.
Nach dem Stand der Technik sind auch Brauseeinrichtungen bekannt (z.B. DE-OS 30 44 310), die als sogenannte Ganzkörperduschen meist vertikale Rahmen aufweisen, in denen radial zum Innenraum der Duscheinrichtung gerichtete Austrittsoffnungen linear angeordnet sind.According to the prior art, shower devices are also known (e.g. DE-OS 30 44 310), which, as so-called whole-body showers, usually have vertical frames in which outlet openings directed radially to the interior of the shower device are linearly arranged.
Für industrielle Zwecke sind verschiedene Brausen mit linearer Anordnung der Austrittsöffnung bekannt, die meist den Zweck verfolgen, einen Flüssigkeitsvorhang zu erzeugen.Various showers with a linear arrangement of the outlet opening are known for industrial purposes, which mostly have the purpose of producing a liquid curtain.
So gibt die DE 93 12 334 UI eine Kühlmittelbrause an, insbesondere für eine Werkzeugmaschine oder dergleichen mit einem Auslaßelement für das Kühlmittel, bei der die Auslaßöffnungen im wesentlichen reihenförmig angeordnet sind. Dabei verfolgt die Erfindung den Zweck ein bewegtes Werk- zeug an jeder Stelle seines Einsatzortes ausreichend mit Kühlmittel zu versorgen. Darstellung der ErfindungFor example, DE 93 12 334 UI specifies a coolant spray, in particular for a machine tool or the like, with an outlet element for the coolant, in which the outlet openings are arranged essentially in rows. The purpose of the invention is to provide a moving tool with sufficient coolant at every point in its place of use. Presentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Handbrause, insbesondere zum Reinigen von Haaren, anzugeben, die den Wasserverbrauch bei gleichzeitiger Verbesserung des Reini- gungseffektes wesentlich verringert. Die Handbrause soll auch für andere handwerkliche und industrielle Reinigungsaufgaben einsetzbar sein.The invention is based on the object of specifying a hand shower, in particular for cleaning hair, which substantially reduces water consumption while at the same time improving the cleaning effect. The hand shower should also be used for other manual and industrial cleaning tasks.
Die Erfindung löst die Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen 2 bis 7 gekennzeichnet.The invention solves the problem by the characterizing features of claim 1. Advantageous refinements are characterized in the subclaims 2 to 7.
Erfindungsgemäße Anwendungen der Handbrause sind im Anspruch 8 gekennzeichnet .Applications of the hand shower according to the invention are characterized in claim 8.
Der erfinderische Kern der vorgeschlagenen Lösung besteht darin, daß mittels einer Vielzahl linienförmig angeord- neter Auslaßöffnungen, feine relativ harte Wasserstrahlen erzeugt werden, die kammartig über die jeweils zu reinigenden bzw. zu spülenden Bereiche der Haare bewegt werden. Dabei dringen die kammartig wirkenden feinen Wasserstrahlen mit hoher Geschwindigkeit tief in die Haarsträhnen ein und spülen, z. B. Seifenreste wirkungsvoll aus dem Haar aus. Gegenüber dem Stand der Technik, bei dem eine erheblich größere Wassermenge relativ ungenutzt über die Haare hinwegläuft, ohne daß ein Großteil des Wassers beim Reinigungsprozeß effektiv genutzt wird, ist bei der erfindungs- gemäßen Einrichtung das Wasser im wesentlichen vollständig am Reinigungsprozeß beteiligt. Die relativ geringe Wassermenge wird konzentriert linienartig wirkend mit hoher hoher Effektivität für den Reinigungsprozeß genutzt.The inventive essence of the proposed solution is that fine, relatively hard water jets are generated by means of a multiplicity of line-shaped outlet openings, which are moved like a comb over the areas of the hair to be cleaned or rinsed. The comb-like fine water jets penetrate deeply into the strands of hair at high speed and rinse, e.g. B. Soap residue effectively from the hair. Compared to the prior art, in which a considerably larger amount of water runs relatively unused over the hair without a large part of the water being effectively used in the cleaning process, the water in the device according to the invention is essentially fully involved in the cleaning process. The relatively small amount of water is used in a concentrated, line-like manner with a high degree of effectiveness for the cleaning process.
Erfindungswesentlich ist, daß sich die einzelnen Wasser- strahlen nach dem Austritt aus den Austrittsoffnungen nicht miteinander vermischen sondern als einzelne Strahlen in die Haarsträhnen eindringen. Voraussetzung dafür ist, daß die Austrittsoffnungen einen relativ geringen Durchmesser aufweisen und die Bohrungsform den austretenden Wasserstrahl nicht auffächert oder gar zerstäubt .It is essential to the invention that the individual water jets do not mix with one another after exiting the outlet openings but penetrate the hair strands as individual jets. The prerequisite for this is that the outlet openings have a relatively small diameter and the bore shape does not fan out or even atomize the emerging water jet.
Die einzelnen Durchmesser und die Anzahl der Austrittsoffnungen werden vorteilhafterweise so gewählt, daß keine gesonderte Druckerzeugung erforderlich ist, sondern der übliche Leitungsdruck vom Wassernetz ausreichend ist.The individual diameters and the number of outlet openings are advantageously chosen so that no separate pressure generation is required, but the usual line pressure from the water network is sufficient.
Als praktikabel haben sich Austrittsoffnungen mit einem Durchmesser zwischen 0,3 bis 0,8 mm erwiesen.Outlet openings with a diameter between 0.3 and 0.8 mm have proven to be practical.
Die erfindungsgemäße Handbrause hat sich bei der bevorzugten Anwendung im Friseurhandwerk in hervorragender Weise bewährt. Der Wasserverbrauch hat sich gegenüber Handduschen nach dem Stand der Technik, bei gleicher oder bes- serer Reinigungsleistung, auf bis zu 20% reduziert. Des weiteren ist es in vorteilhafter Weise möglich, ausschließlich einzelne Haarsträhnen oder Haarbereiche zu behandeln. Dabei wird gleichzeitig der entsprechende Kopfhautbereich in angenehmer Weise durch die feinen Wasserstrahlen massiert.The hand shower according to the invention has proven itself in an outstanding manner in the preferred application in the hairdressing trade. The water consumption has been reduced to up to 20% compared to state-of-the-art hand showers with the same or better cleaning performance. Furthermore, it is advantageously possible to treat only individual strands or areas of hair. At the same time, the corresponding scalp area is massaged in a pleasant way by the fine water jets.
Da die einzelnen Wassernetze oft sehr unterschiedliche Drücke aufweisen, ist es vorteilhaft am Wassereintritt in die Handbrause eine auswechselbare oder einstellbare Drosseleinrichtung, z. B. eine Drosselscheibe, anzuordnen. Damit kann eine relativ stabile Wasseraustrittsgeschwindigkeit aus der Handbrause eingestellt werden. Der Wasserzulauf braucht dadurch nicht lange reguliert zu werden, sondern es genügt ein Auf/Zu-Wasserhahn um stets einen gewünschten gleichmäßigen Wasseraustritt zu erzielen.Since the individual water networks often have very different pressures, it is advantageous at the water inlet in the hand shower a replaceable or adjustable throttle device, for. B. to arrange a throttle disc. This enables a relatively stable water outlet speed to be set from the hand shower. The water inlet does not need to be regulated for a long time, an open / closed tap is all that is required to achieve the desired, even water outlet.
Als besonders vorteilhaft hat sich die Anordnung derThe arrangement of the
Austrittsoffnungen in zwei Reihen erwiesen. Es ist aber auch möglich, die Austrittsoffnungen in nur einer Reihe oder in drei bis fünf Reihen anzuordnen. Bei nur einer Reihe sollte der Wasserdurchlaß je Austrittsöffnung relativ erhöht werden. Bei vier und mehr Reihen geht der erfindungsgemäße Effekt langsam verloren und man nähert sich wieder dem Stand der Technik, bei dem das flächig auf die Haare aufgebrachte Wasser ohne die erwünschte erfinderische Wirkung über die Haare abläuft .Exit openings proved in two rows. But it is also possible to have the exit openings in just one row or to be arranged in three to five rows. If there is only one row, the water passage per outlet opening should be increased relatively. In the case of four or more rows, the effect according to the invention is slowly lost and the state of the art is again approached, in which the water applied to the hair over the surface runs over the hair without the desired inventive effect.
Je nach dem konkreten Anwendungszweck kann es vorteilhaft sein, wenn die WasserZuführungen zu den einzelnen Reihen der Austrittsoffnungen einzeln absperrbar sind. Damit kann der Wasseraustritt wahlweise über eine oder mehrere Reihen reguliert werden. Auch ist es vorteilhaft, an der Handbrause ein Wasserstopventil und gegebenenfalls eine kalt- warm-Reguliereinrichtung vorzusehen.Depending on the specific application, it can be advantageous if the water inlets to the individual rows of the outlet openings can be shut off individually. This means that the water outlet can be regulated over one or more rows. It is also advantageous to provide a water stop valve and, if necessary, a cold-warm regulating device on the hand shower.
In der Praxis hat sich gezeigt, daß die als Haardusche konzipierte Handbrause sich in vorteilhafter Weise auch für andere Reinigungsaufgaben einsetzen läßt, wobei die wesentlichen Vorteile des geringen Wasserverbrauches bei hoher Reinigungsleistung in gleicher Weise eintreten.In practice, it has been shown that the hand shower designed as a hair shower can advantageously also be used for other cleaning tasks, with the essential advantages of low water consumption and high cleaning performance occurring in the same way.
So können z. B. Arbeitsplätze für Fleisch- oder Fischhändler, sowohl mit Oberflächen aus Holz, Stein oder Kunststoff, in einfacher Weise wirksam saubergehalten werden. Die mit hoher Geschwindigkeit auf die Oberfläche auftreffenden feinen Wasserstrahlen haben einen hohen Reinigungs- effekt, ohne daß die Umgebung in unerwünschter Weise eingenäßt wird. Ein besonderer Vorteil besteht dabei darin, daß die feinen Wasserstrahlen in relativ geringer Entfernung vom Wasseraustritt ihre Geschwindigkeit durch die Wirkung der Atmosphäre verloren haben und somit nicht weit spritzen können. Die effektive Entfernung der Arbeitsoberfläche vom Wasseraustritt liegt zwischen wenigen Zentimetern und maximal zwanzig bis dreißig Zentimetern. Auch im handwerklichen und industriellen Bereich können Abriebe, Stäube, Späne u.a. vorteilhaft entfernt und abgespült werden.So z. B. jobs for meat or fish dealers, both with surfaces made of wood, stone or plastic, can be kept clean effectively in a simple manner. The fine water jets hitting the surface at high speed have a high cleaning effect without undesirably wetting the surroundings. A particular advantage is that the fine water jets at a relatively short distance from the water outlet have lost their speed due to the effect of the atmosphere and therefore cannot spray far. The effective distance of the work surface from the water outlet is between a few centimeters and a maximum of twenty to thirty centimeters. Abrasion, dust, chips, etc. can also advantageously be removed and rinsed off in the craft and industrial sector.
Dabei ist es auch möglich, statt Wasser spezielle Reini- gungsmittel als Reinigungsflüssigkeit einzusetzen.It is also possible to use special cleaning agents as the cleaning liquid instead of water.
Die Erfindung soll nachstehend an einem Ausführungsbei- spiel näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment.
Die zugehörige Zeichnung zeigt in Figur 1 eine erfindungsgemäße Handbrause in Seitenansicht.The associated drawing shows a hand shower according to the invention in side view in FIG.
Figur 2 zeigt die Ansicht Z in Figur 1.FIG. 2 shows the view Z in FIG. 1.
Figur 3 zeigt den Schnitt A-A in Figur 2.Figure 3 shows the section A-A in Figure 2.
Das Ausführungsbeispiel wird anhand einer in üblicher Weise gestalteten Handbrause entsprechend Figur 1 mit einem Griff 1, einem Brausenkopf 2, aus der im Betrieb die einzelnen Wasserstrahlen 3 austreten, einem Schlauch 4, über den das Wasser in die Handbrause geleitet wird, und eine Schlauchverbindung 5, mittels der der Schlauch 4 an dem Griff 1 befestigt wird, beschrieben.The exemplary embodiment is based on a hand shower according to FIG. 1 with a handle 1, a shower head 2, from which the individual water jets 3 emerge during operation, a hose 4, via which the water is led into the hand shower, and a hose connection 5 , by means of which the hose 4 is fastened to the handle 1.
Die eigentliche Erfindung ist in Figur 2 näher darge- stellt. Der Brausenkopf 2 ist länglich ausgebildet und weist in zwei parallelen Reihen 6 und 7 die Austrittsoffnungen 8 auf . Dabei sind die Austrittsoffnungen 8 innerhalb einer Reihe mit einem Abstand b zueinander angeordnet und die Austrittsoffnungen 8 der Reihe 6 gegenüber den Austrittsoffnungen 8 der Reihe 7 in dem Abstand b/2 versetzt. Es ist aber auch möglich, die Austrittsoffnungen 8 relativ zur Längsachse der Reihen 6 und 7 zueinander rechtwinklig in der gleichen Querachse anzuordnen. Die Länge der Reihen 6 bzw. 7, mit den Austrittsoffnungen 8 richtet sich nach dem jeweiligen Bedarf und beträgt im Beispiel ca. 50 mm.The actual invention is shown in more detail in FIG. 2. The shower head 2 is elongated and has the outlet openings 8 in two parallel rows 6 and 7. The outlet openings 8 are arranged within a row at a distance b from one another and the outlet openings 8 of the row 6 are offset from the outlet openings 8 of the row 7 at a distance b / 2. However, it is also possible to arrange the outlet openings 8 at right angles to one another in the same transverse axis relative to the longitudinal axis of the rows 6 and 7. The length of the rows 6 and 7 with the outlet openings 8 depends on the respective requirement and is approximately 50 mm in the example.
Der Querschnitt der Austrittsoffnungen 8, wie er in Figur 3 erkennbar ist, entspricht einer zylindrischen Bohrung mit scharfen Kanten am Austritt des Wassers. Damit werden in der Praxis in exakter Weise geradlinig ausströmende Wasserstrahlen 3 erzielt, die sich nicht wesentlich aufweiten oder auseinanderstäuben. Im Beispiel ist eine gesonderte Düsenplatte 9 an dem Brausenkopf 2 angesetzt .The cross section of the outlet openings 8, as can be seen in FIG. 3, corresponds to a cylindrical bore with sharp edges at the outlet of the water. In this way, straight flowing water jets 3 are obtained in practice in an exact manner, which do not widen or dust apart significantly. In the example, a separate nozzle plate 9 is attached to the shower head 2.
Mit der Handbrause gemäß dem vorstehenden Ausführungs- beispiel wurde in der Erprobung wesentliche Einsparungen an Wasser erzielt . Während beim Einsatz von üblichen Handbrausen nach dem Stand der Technik für eine durchschnitt- liehe Haarwäsche in einem Damensalon ca. 9 Liter Wasser verbraucht wurde, lag der Wasserverbrauch mit der erfindungsgemäßen Handdusche bei ca. 2 Liter. Von besonderem Vorteil ist dabei, daß z. B. nach dem Färben einzelner Haarsträhnen, diese separiert und intensiv ausgespült werden können, ohne daß andere Haarbereiche in unerwünschter Weise ebenfalls eingenäßt werden.With the hand shower according to the above embodiment, considerable savings in water were achieved in the test. While using conventional hand showers according to the prior art for average hair washing in a women's salon, about 9 liters of water were used, the water consumption with the hand shower according to the invention was about 2 liters. It is particularly advantageous that z. B. after dyeing individual strands of hair, these can be separated and rinsed intensively without other hair areas are also undesirably wet.
Auch wurde von den einzelnen Personen, deren Haare einer Wäsche unterzogen wurde, betont, daß die feinen harten Wasserstrahlen eine angenehme Kopfhautmassage bewirken.It was also emphasized by the individual, whose hair was subjected to a wash, that the fine, hard water jets bring about a pleasant scalp massage.
Die Erfindung ist selbstverständlich nicht auf das beschriebene Ausführungsbeispiel beschränkt . So ist es ohne weiteres möglich, die Reihen 6 und 7 in einem leichten Bogen auszuführen, so daß die Linie der Wasserstrahlen, bei einer handgerechten Neigung des Brausenkopfes 2 um ca. 45°, etwa der Rundung des menschlichen Kopfes entspricht. Insbesondere ist es auch möglich den Handgriff anders zu gestalten. Zusätzlich kann in bekannter Weise am Griff 1 auch ein Wasserstopventil oder ein kalt-warm-Mischventil vorhanden sein.The invention is of course not limited to the exemplary embodiment described. So it is easily possible to carry out the rows 6 and 7 in a slight curve, so that the line of the water jets corresponds to the rounding of the human head with a hand-appropriate inclination of the shower head 2 by approx. 45 °. In particular, it is also possible to design the handle differently. In addition, a water stop valve or a cold-hot mixing valve can also be present on the handle 1 in a known manner.
Im handwerklichen und industriellen Bereich kann die "Handbrause", wenn die Reinigungsbewegung definitiv immer die gleiche ist, auch an einer festen und/oder beweglichen Halterung angeordnet werden. In the craft and industrial sector, if the cleaning movement is definitely always the same, the "hand shower" can also be arranged on a fixed and / or movable holder.
