Description
Die Erfindung betrifft eine Anschlussarmatur, mit einem gegossenen Wasserführungskörper, mit einem Zuflussrohrstutzen mit Kragen, wobei der Zuflussrohrstutzen eine frei drehbare Überwurfmutter trägt, zum hydraulischen Verbinden einer wasserführenden Haushaltmaschine, insbesondere Wasch- oder Geschirrspülmaschine, mit einem Was-serhahn eines Hauswassernetzes.
Eine derartige Anschlussarmatur ist durch die DE 4 304 712 A1 bekannt. Bei dieser Anschlussarmatur ist der Zuflussrohrstutzen des Wasserführungskörpers für einen direkten Anschluss an den Wasserhahn eines Hauswassernetzes ausgebildet. Hierdurch ergeben sich Schwierigkeiten beim Anbringen der Überwurfmutter an dem Zuflussrohr-stutzen. Diese muss dadurch einen geteilten, gesondert einlegbaren Sicherungsring ha-ben, damit die Überwurfmutter auf dem Zuflussrohrstutzen hält und dennoch frei auf ihm drehbar ist. Da dieser Sicherungsring einen Hinterschnitt am Zuflussrohrstutzen hintergreift, muss dieser mehrteilig ausgebildet und nach dem Anbringen der Über-wurfmutter mit dem Zuflussrohrstutzen verbunden werden. Dies erfordert einen hohen Arbeitsaufwand.
Wegen der hohen, von der Überwurfmutter aufzunehmenden Kräfte muss die Verbindung der Halteelemente stabil genug ausgeführt werden, was abermals hohe Kosten verursacht.
Der Erfindung liegt die Aufgabe zu Grunde, eine Anschlussarmatur der eingangs be-schriebenen Art so weiterzubilden, dass sie wesentlich kostengünstiger hergestellt wer-den kann.
Die Lösung der gestellten Aufgabe gelingt nach der Erfindung gemäss dem kennzeichnenden Teil von Anspruch 1.
Durch die Verwendung eines gesonderten, an den Wasserführungskörper verbindbaren Zuflussrohrstutzens besteht die Möglichkeit, den Zuflussrohrstutzen und die Überwurf-mutter vor dem Verbinden mit dem Wasserführungskörper zu koppeln, ohne dass hier-für gesonderte Halteteile erforderlich wären.
Das Verbinden des Zuflussrohrstutzens mit dem Wasserführungskörper kann auf unter-schiedliche Weise erfolgen, so z.B. durch Umspritzen, Verschweissen, Verpressen oder auch durch Verschrauben.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend näher erläutert.
Zur Frischwasserzuführung zu einer nicht dargestellten Wasch- oder Geschirrspülma-schine und einem ebenfalls nicht dargestellten Wasserhahn eines Hauswassernetzes kann in bekannter Weise ein Sicherheitsschlauch dienen. Ein solcher Sicherheits-schlauch besteht aus einem Druckschlauch 1 und einem diesen mit radialem Abstand umgebenden Hüllschlauch 2. Mittels der Anschlussarmatur ist der Sicherheitsschlauch mit dem Wasserhahn verbindbar. Der Druckschlauch 1 ist dazu an den Abfluss-rohrstut-zen 3 eines Wasserführungskörpers 5 an der Anschlussarmatur angeschlossen, der durch ein Magnetventil 4 gegen Zustrom von Frischwasser verschliessbar ist.
Über eine Verbindung 6 ist der Zuflussrohrstutzen 7 an den Wasserführungskörper 5 angeschlossen. Der Zuflussrohrstutzen 7 trägt an seinem freien, mit dem Wasserhahn zu verbindenden Ende eine Überwurfmutter 8. Vor dem Verbinden des Zuflussrohr-stut-zens 7 mit dem Wasserführungskörper 5 wird der Zuflussrohrstutzen 7 mit seinem zu verbindenden Ende durch die Überwurfmutter 8 gesteckt, bis der Kragen 10 des Zu-flussrohrstutzens 7 von innen am Flansch 11 der Überwurfmutter zur Anlage kommt. Hierdurch ist eine hohen Kräften standhaltende Verbindung von Überwurfmutter 8 und Zuflussrohrstutzen 7 gegeben.
Nach dem Überziehen der Überwurfmutter 8 wird der Zuflussrohrstutzen 7 in geeigne-ter Weise im Bereich der Verbindung 6 mit dem Wasserführungskörper 5 verbunden. Dazu kann der Zuflussrohrstutzen 7 mit dem Wasserführungskörper 5 verschweisst oder verpresst werden. Der Zuflussrohrstutzen 7 kann auch durch Umspritzen mit Material des Wasserführungskörpers 5 oder mit zusätzlichem Material oder durch Verschrauben mit dem Wasserführungskörper 5 verbunden werden.
Durch die erfindungsgemässe Massnahme entfällt die Montage eines mehrteiligen Sicherungsringes. Die Überwurfmutter 8 ist unwiderruflich unverlierbar.
The invention relates to a connection fitting, with a cast water guide body, with an inflow pipe socket with a collar, the inflow pipe socket carrying a freely rotatable union nut, for hydraulically connecting a water-carrying household machine, in particular a washing machine or dishwasher, to a water tap in a domestic water network.
Such a connection fitting is known from DE 4 304 712 A1. In this connection fitting, the inlet pipe socket of the water guide body is designed for a direct connection to the tap of a domestic water network. This results in difficulties in attaching the union nut to the inlet pipe socket. This must have a split, separately insertable locking ring so that the union nut holds on the inlet pipe socket and can still be freely rotated on it. Since this retaining ring engages behind an undercut on the inflow pipe socket, it must be designed in several parts and connected to the inflow pipe socket after the union nut has been attached. This requires a lot of work.
Because of the high forces to be absorbed by the union nut, the connection of the holding elements must be stable enough, which again causes high costs.
The invention is based on the object of developing a connection fitting of the type described at the outset in such a way that it can be produced much more cost-effectively.
The object is achieved according to the invention according to the characterizing part of claim 1.
By using a separate inflow pipe socket that can be connected to the water guide body, it is possible to couple the inflow pipe socket and the union nut before connecting to the water guide body, without the need for separate holding parts.
The connection of the inlet pipe socket to the water guiding body can be done in different ways, e.g. by overmolding, welding, pressing or also by screwing.
Based on an embodiment shown in the drawing, the invention is explained in more detail below.
In a known manner, a safety hose can be used to supply fresh water to a washing machine or dishwasher, not shown, and to a faucet, also not shown, of a domestic water network. Such a safety hose consists of a pressure hose 1 and an enveloping hose 2 surrounding it at a radial distance. The safety hose can be connected to the tap by means of the connection fitting. For this purpose, the pressure hose 1 is connected to the drain pipe socket 3 of a water guide body 5 on the connection fitting, which can be closed by a solenoid valve 4 against the inflow of fresh water.
The inflow pipe socket 7 is connected to the water guide body 5 via a connection 6. The inflow pipe socket 7 carries at its free end to be connected to the tap a union nut 8. Before connecting the inflow pipe socket 7 to the water guide body 5, the inflow pipe socket 7 with its end to be connected is inserted through the union nut 8 until the collar 10 of the inlet pipe socket 7 comes into contact with the flange 11 of the union nut from the inside. This provides a high-strength connection between the union nut 8 and the inlet pipe socket 7.
After the union nut 8 has been pulled over, the inflow pipe socket 7 is connected in a suitable manner in the region of the connection 6 to the water guide body 5. For this purpose, the inflow pipe socket 7 can be welded or pressed to the water guide body 5. The inflow pipe socket 7 can also be connected to the material of the water guide body 5 by injection molding or with additional material or by screwing it to the water guide body 5.
Due to the measure according to the invention, the assembly of a multi-part locking ring is not necessary. The union nut 8 is irrevocably captive.
