Description
Die vorliegende Erfindung betrifft Sanitärarmaturen gemäß dem Oberbegriff des Patentanspruchs 1 und ein Verfahren zur Herstellung von Sanitärarmaturen gemäß Patentanspruch 13.The present invention relates to sanitary fittings according to the preamble of patent claim 1 and a method for the production of sanitary fittings according to claim 13.
Herstellverfahren für Sanitärarmaturen sind bekannt. Oftmals werden sie als Gussteile in Dauerformen ausgebildet, da sich diese in einfacher Weise auch mit komplizierten Formgebungen realisieren lassen. Zur Führung des Fluids innerhalb der Gussgehäuse ist es bekannt, Kanäle einzubringen, die je nach Anzahl und Anordnung der gewünschten Führungen komplizierte Gießkernformen erfordern. Zur Herstellung von Gießkernen wird in einer Kernschießmaschine mit Bindemittel versetzter Formsand mit einem bestimmten Schussdruck und -temperatur in eine Kernform gepresst. Nach dem Aushärten des so hergestellten Gusskerns wird dieser in die Gießform eingebaut. Im Anschluss an den erfolgten Abguss wird der Sand durch im Gussstück platzierte Öffnungen entfernt. Je nach Führung der Wasserwege in den Armaturen entstehen Gussteile mit hohem Gewicht und hohem Materialverbrauch.Manufacturing process for sanitary fittings are known. Often they are formed as castings in permanent molds, as they can be realized in a simple manner with complicated shapes. To guide the fluid within the cast housing, it is known to introduce channels that require complicated Gießkernformen depending on the number and arrangement of the desired guides. For the production of foundry cores molding sand mixed with binding agent is pressed into a core mold with a certain shot pressure and temperature in a core shooting machine. After curing of the casting core thus produced, it is installed in the casting mold. Following the casting, the sand is removed through openings placed in the casting. Depending on the guidance of the waterways in the fittings, castings with high weight and high material consumption are produced.
Um Gewicht einzusparen ist es bekannt, Wasserführungen getrennt von Armaturengehäusen herzustellen, diese mit den Bauteilen, die Funktionsbauteile der Armatur wie Thermoelemente oder Mischkartuschen enthalten zu verbinden und anschließend mit einer Gehäusehülle zu versehen. Aus der
Derartige Armaturen bestehen jedoch aus vielen Einzelteilen, so dass sich der Montageaufwand erheblich vergrößert.In order to save weight, it is known to produce water ducts separately from valve body housings, to connect these with the components that contain functional components of the valve such as thermocouples or mixing cartridges and then to provide them with a housing shell. From the
However, such fittings consist of many items, so that the assembly costs significantly increased.
Vor diesem Hintergrund besteht die Aufgabe der Erfindung darin, eine Sanitärarmatur mit geringem Montageaufwand zu schaffen, bei der die Wasserführung getrennt von einem Gehäuse hergestellt werden kann.Against this background, the object of the invention is to provide a sanitary fitting with low installation costs, in which the water supply can be made separately from a housing.
Diese Aufgabe wird erfindungsgemäß durch eine Sanitärarmatur mit den Merkmalen des Patentanspruchs 1 und durch ein Verfahren zur Herstellung einer Sanitärarmatur gemäß Patentanspruch 13 gelöst. Günstige Ausgestaltungsformen sind Gegenstand von Unteransprüchen.This object is achieved by a sanitary fitting with the features of claim 1 and by a method for producing a sanitary fitting according to claim 13. Favorable embodiments are the subject of dependent claims.
Dazu wird eine Sanitärarmatur, die ein Gehäuse sowie ein Wasserführungsmodul umfasst, wobei das Gehäuse Anschlüsse für einen Kalt- und einen Heißwasserzulauf und einen Auslass für Mischwasser aufweist, und das Wasserführungsmodul ein vorgeformtes Hohlprofil umfasst und wenigstens einen Einlass für Kalt-, Heiß oder Mischwasser, bereitgestellt, bei der das Gehäuse einteilig und das Wasserführungsmodul dichtend mit dem Gehäuse verbindbar ist. Weiterhin kann das Wasserführungsmodul auch je einen Einlass für Kalt und Heißwasser umfassen. Der Vorteil einer derartigen Sanitärarmatur mit einem einteiligen Gehäuse und einer von diesem getrennt hergestellten Wasserführung besteht darin, dass bei einem Gussgehäuse die Komplexität der Sandkernherstellung und des Gießprozesses stark reduziert wird, da nur noch eine Kammer mit den notwendigen Öffnungen hergestellt werden muss. Dadurch vereinfacht sich auch das Entsanden der Armatur, wodurch die Verschleppung des Sandes in nachfolgende Prozesse reduziert wird. Hierdurch werden Werkzeugverschleiß durch Sandkörner bei der mechanischen Bearbeitung, Oberflächenfehler und starke Verschmutzungen im Galvanikbecken weitgehend vermieden.For this purpose, a sanitary fitting comprising a housing and a water supply module, wherein the housing has connections for a cold and a hot water supply and an outlet for mixed water, and the water supply module comprises a preformed hollow profile and at least one inlet for cold, hot or mixed water, provided in which the housing is in one piece and the water supply module is sealingly connectable to the housing. Furthermore, the water supply module may also each include an inlet for cold and hot water. The advantage of such a sanitary fitting with a one-piece housing and a water guide made separately from this is that in a cast housing, the complexity of Sandkernherstellung and the casting process is greatly reduced, since only one chamber with the necessary openings must be made. This also simplifies the desanding of the fitting, which reduces the carryover of the sand into subsequent processes. As a result, tool wear by sand grains during mechanical processing, surface defects and heavy contamination in the galvanic tank are largely avoided.
Das Gehäuse weist neben den Öffnungen für die Wasseranschlüsse und den Wasserauslass eine weitere Öffnung zum Einführen des Wasserführungsmoduls auf. Das Wasserführungsmodul kann somit von einer Seite in das Gehäuse eingeschoben und form- oder kraftschlüssig mit diesem unter Verwendung von Dichtmitteln verbunden werden. Diese Art der Herstellung gewährt die größtmögliche Freiheit bei der Auswahl der Materialien für Gehäuse und Wasserführungsmodul, da die Armatur so hergestellt werden kann, dass das Wasser nicht mit dem Gehäuse in Berührung kommt.The housing has, in addition to the openings for the water connections and the water outlet on another opening for insertion of the water supply module. The water guide module can thus be inserted from one side into the housing and positively or non-positively connected with this using sealants. This type of manufacturing gives the utmost freedom in choosing the materials for housing and water supply module, since the fitting can be made so that the water does not come into contact with the housing.
Gemäß einer Ausgestaltung der Erfindung sind die Aufnahmen für ein Funktionsbauteil, insbesondere ein Thermostatelement, eine Mischkartusche oder ein Ventiloberteil im Wasserführungsmodul und nicht im Gehäuse vorgesehen. Dies vereinfacht den Aufwand beim Herstellen der Gehäuseinnenform.According to one embodiment of the invention, the receptacles for a functional component, in particular a thermostatic element, a mixing cartridge or a valve top are provided in the water supply module and not in the housing. This simplifies the effort in producing the housing's interior.
Eine weitere vorteilhafte Weiterbildung sieht vor, dass das Wasserführungsmodul zwei getrennte Wasserwege umfasst, wobei der eine Wasserweg den anderen wenigstens teilweise radial umgibt. Hierdurch kann eine sehr Platz sparende Bauweise erzielt werden.A further advantageous embodiment provides that the water supply module comprises two separate water paths, wherein the one waterway surrounds the other at least partially radially. As a result, a very space-saving design can be achieved.
Eine vorteilhafte Ausgestaltung sieht vor, dass das Wasserführungsmodul, beispielsweise die Mischwasserführung, aus einem Rohr besteht und Ein- und Auslass jeweils am Rohrende vorgesehen sind. Das Wasserführungsmodul wird mit O-Ringen versehen und in dafür vorgesehene Aufnahmen im Gehäuse eingeschoben. Die Fixierung erfolgt über den Reibschluss der Dichtmitttel.
Gemäß einer Weiterbildung der Erfindung sind die Einlässe für Kalt- und Heißwasser am Wasserführungsmodul in radialer Richtung vorgesehen. Dabei ist das Wasserführungsmodul bzw. das Hohlprofil so ausgeformt, dass dichte Übergänge zu den Anschlüssen für Kalt- und Heißwasser erzielt werden. Hierzu sind die Rohre oder zylindrischen Hohlprofile, aus denen das Wasserführungsmodul besteht, in diesem Bereich abgeflacht und beispielsweise mit einer Nut für einen O-Ring versehen.An advantageous embodiment provides that the water supply module, for example, the mixed water guide, consists of a tube and inlet and outlet are respectively provided at the pipe end. The water supply module is equipped with O-rings and inserted into the receptacles provided in the housing. The fixation takes place via the frictional engagement of the sealant.
According to one embodiment of the invention, the inlets for cold and hot water are provided on the water supply module in the radial direction. In this case, the water guide module or the hollow profile is formed so that tight transitions to the connections for cold and hot water can be achieved. For this purpose, the tubes or cylindrical hollow profiles, which make up the water supply module, flattened in this area and provided for example with a groove for an O-ring.
Bei einer Ausgestaltung der Sanitärarmatur ist ausschließlich der Einlass für Heißwasser am Wasserführungsmodul dichtend mit dem Anschluss für den Heißwasserzulauf am Gehäuse verbindbar. Dies bedeutet, dass das Kaltwasser am Anschluss für Kaltwasser in das Gehäuse gelangt und die Wasserführung und den Gehäuseinnenraum umströmt. Somit wird ein sogenannter "Cool-touch"-Effekt erzielt, da die Wasserwege, die heißes oder warmes Wasser führen, nicht mit der Oberfläche der Armatur in Verbindung stehen, sondern von kaltem Wasser umgeben sind. Verbrühungen des Nutzers durch Berühren beim Duschen oder Reinigen der Armatur sind damit ausgeschlossen. Hierbei ist die Einteiligkeit des Gehäuses von großem Vorteil, da die Dichtstellen auf die Anschlüsse und den Auslass reduziert werden. Die Einlässe für Kalt- und Heißwasser am Wasserführungsmodul sind dabei im Bereich der Aufnahme für ein Thermostatelement angeordnet. Dies bedeutet, dass der Thermostat auf der Seite des Heißwasseranschlusses angeordnet ist und das Heißwasser direkt vom Gehäuseanschluss in den Thermostatbereich geführt wird. Das Kaltwasser umspült das Gehäuseinnere und die Wasserführung von außen bis es an den Einlass im Thermostatbereich in die Wasserführung gelangt.In one embodiment of the sanitary fitting only the inlet for hot water on the water supply module is sealingly connected to the connection for the hot water supply to the housing. This means that the cold water enters the housing at the connection for cold water and flows around the water supply and the housing interior. Thus, a so-called "cool-touch" effect is achieved, since the waterways that carry hot or warm water are not connected to the surface of the fitting, but are surrounded by cold water. Scalding the user by touching while showering or cleaning the valve are excluded. Here, the one-piece design of the housing is of great advantage, since the sealing points are reduced to the connections and the outlet. The inlets for cold and hot water on the water supply module are arranged in the region of the receptacle for a thermostatic element. This means that the thermostat is located on the side of the hot water connection and the hot water is led directly from the housing connection into the thermostat area. The cold water flows around the inside of the housing and the water supply from the outside until it reaches the inlet in the thermostat area.
Bei einer weiteren Ausgestaltung ist das Wasserführungsmodul so ausgeformt, dass sowohl der Gehäuseanschluss für Kaltwasser mit einem Einlass für Kaltwasser am Wasserführungsmodul als auch der Gehäuseanschluss für Heißwasser mit einem Einlass am Wasserführungsmodul dichtend verbindbar ist.In a further embodiment, the water supply module is formed so that both the housing connection for cold water with an inlet for cold water at the water supply module and the housing connection for hot water with an inlet to the water supply module is sealingly connected.
Die Bauweise des Wasserführungsmoduls ermöglicht weiterhin, die Auslässe an unterschiedlichen Stellen zu positionieren, so dass sie mit dem Mischwasserauslass am Gehäuse korrespondieren. Dies ist jeweils davon abhängig, ob das Mischwasser, dessen Menge über ein Ventiloberteil gesteuert wird, im inneren oder äußeren Wasserweg geführt wird. Dementsprechend ist der Auslass des Wasserführungsmoduls nur am äußeren Wasserweg oder am inneren Wasserweg mit dem Mischwasserauslass des Gehäuses verbunden.The design of the water supply module further allows the outlets to be positioned at different locations so that they correspond to the mixed water outlet on the housing. This is in each case dependent on whether the mixed water, whose amount is controlled by a valve top, is guided in the inner or outer waterway. Accordingly, the outlet of the water supply module is only on the outside Waterway or at the inner waterway connected to the mixed water outlet of the housing.
Für das Gehäuse und/oder das Wasserführungsmodul sind sowohl Materialien aus Kunststoff als auch aus Metall verwendbar. Dadurch bieten sich gerade zur Formgebung der Hohlprofile für das Wasserführungsmodul eine Vielzahl von Verfahren an. Gerade zur Herstellung der Bereiche für die Aufnahme der Funktionsbauteile bieten sich bei Hohlprofilen aus Metall Verfahren wie "Heatforming" an, da hierbei dünne Wandstärken und somit eine leichte und Material sparende Konstruktion erzielt werden kann.Both plastic and metal materials can be used for the housing and / or the water-guiding module. As a result, a large number of methods are currently available for shaping the hollow profiles for the water guidance module. Especially for the production of the areas for receiving the functional components are offered in hollow profiles made of metal processes such as "heat forming", since in this case thin wall thicknesses and thus a lightweight and material-saving construction can be achieved.
Somit wird durch die Erfindung ein Verfahren zur Herstellung von Sanitärarmaturen bereitgestellt, bei dem zunächst ein einteiliges Gehäuses für eine Sanitärarmatur mit Anschlüssen für einen Kalt- und einen Warmwasserzulauf und einem Mischwasserauslass sowie ein Wasserführungsmodul getrennt voneinander gefertigt werden, wobei die Reihenfolge nicht von Belang ist. Anschließend wird das Wasserführungsmodul derart in das Gehäuse eingelegt, dass beim Einbauvorgang des Wasserführungsmoduls im Bereich einer Anschlussstelle und im Bereich des Mischwasserauslasses ein dichter Verbund von Gehäuse und Wasserführungsmodul entsteht. Dieser Verbund kann beispielsweise durch formschlüssige oder kraftschlüssige Verbindungen zwischen Gehäuse und Wasserführungsmodul erzielt werden, wobei jeweils geeignete Dichtmittel an den Verbindungsstellen zum Einsatz kommen.Thus, the invention provides a method for the production of sanitary fittings, in which initially a one-piece housing for a sanitary fitting with connections for a cold and a hot water inlet and a mixed water outlet and a water supply module are made separately, the order is not important. Subsequently, the water supply module is inserted into the housing in such a way that during the installation process of the water supply module in the region of a connection point and in the area of the mixed water outlet, a dense composite of housing and water supply module is formed. This composite can be achieved for example by positive or non-positive connections between the housing and water supply module, each suitable sealing means are used at the connection points.
