Description

• – einen Anschlussgrundkörper mit wenigstens je einem Anschluss für eine Wasserzulaufleitung und für eine Mischwasserleitung aufweist, welche Anschlüsse sich jeweils in einem Wasserführungskanal im Inneren des Anschlussgrundkörpers fortsetzen, der in einer Anschlussbohrung an einer Anschlussfläche zum Aufsetzen einer Sanitärarmatur austritt, und
• – ein durchströmbares Verbindungselement zur Verbindung von zwei Anschlussbohrungen.

The invention relates to a connecting and flushing unit for a flush-mounted sanitary fitting, which comprises at least:

• A connecting body having at least one respective connection for a water supply line and for a mixed water line, which connections each continue in a water guide channel in the interior of the connection body, which emerges in a connection bore on a connection surface for placing a sanitary fitting, and
• - A through-flow connection element for connecting two connection holes.

From the DE 10 2005 041 920 is known a connection body, on which an attachment element can be placed, which contains mixer and Umstelleinheiten and forms a sanitary fitting together with the connection body. The connection body is installed in a wall opening or niche and connected to connection lines for cold and hot water as well as for at least one mixed water outlet. For example, a mixed water outlet leads to a hand shower and to a bath spout. The pipe connections are installed in the shell phase of an installation and then plastered. There remains only a wall opening which is so large that later, when the wall is completely tiled, the fitting attachment element is inserted therein. From this then only protrudes a cover plate and at least one operating element beyond the wall surface.

In order to keep the necessary for the insertion of the attachment element opening during plastering and applying the tiles, the connection body is usually used in a protective element, which has at least one tubular section formed of a flexible material.

According to the current regulations, it is necessary to rinse thoroughly an installation intended for connection to the public drinking water supply and to check for pressure tightness.

A so-called rinse block is for example from the EP 1 0026 243 B1 known, which can be placed on the terminal body instead of the attachment element, which contains the mixing and Umstellelemente the sanitary fitting. Channels formed within the purge block allow the various port holes on the port main body to mutually interconnect to purge the conduits such that the water exits at one of the mixed water outlets. Also, a flow path can be blocked to determine whether there is a leak in one of the connections made to the terminal body at the upcoming line pressure.

The disadvantage is that the flushing block must be fastened in the depth of the wall opening on the connection base body. In addition, the flushing block for producing the various flow paths must also be repeatedly removed, rotated and fixed again, which is cumbersome especially for a narrow inner diameter of the protective element.

The object of the present invention is therefore to provide a cost-effective connection and flushing unit for a sanitary fitting, with which also an already installed and connected to the water pipes connection body can be tested.

This object is achieved by a connection and flushing unit with the features of claim 1.

Through the internal threads in the connection bores of the connection body first screw plug can be used as dummy plugs in the shell construction phase to prevent ingress of dirt in the water-carrying paths.

For this purpose, in particular, such screw plug can be used in which the head portion of the screw plug is formed as a cylindrical sleeve whose length is a multiple of the length of the threaded portion. Such protective plugs are known for the protection of water outlet openings at the pipe ends during plastering and other shell work and are available at low cost. They also already have a ring seal for sealing against the connection base.

For flushing then at least two of the screw plug are removed and instead, flushing tubes are screwed, the end each have a compatible with the internal thread of the connection bore male thread paragraph. Through the use of rigid pipes, screwing in is also possible with connection bodies installed deep in the wall. The connection to a water connection for flushing the line can then take place at the outer end. Likewise, two of the port bores may be connected together to pass water through the port main body to a port for a shower hose or tub inlet. For this purpose, a connecting hose for connecting two rinsing pipes with each other may be part of the unit.

Also, the purge tubes and the connecting tube can be integrally formed, wherein at least one of the external thread heels is formed on a relative to the end of the purge tube rotatable sleeve. Thus, a U-shaped water transfer from one of the connection holes to another connection hole can be created in a simple manner.

Even a rinse with only one rinse pipe is possible. In this case, the water can be added or removed through the flushing pipe and exits freely at the end of the pipe or it takes place discharge with a hose to a floor drain.

The invention will be explained in more detail using an exemplary embodiment and with reference to the drawing. The figures show each in perspective view:

1 a connection body with inserted screw plug in perspective view;

2 the connection body with screw plug and a flushing pipe in section and

3 the connection body with screw plug and a flushing pipe in perspective view.

1 shows a connection body 10 , which consists for example of cast brass. He has four connecting pieces 15 , Which are arranged offset by 90 ° to each other and point radially outward. They can be provided with an internal thread into which a water pipe or other connection part can be screwed. At the top of the connection body 10 is a smooth interface 11 formed having multiple connection holes 12 having. Between the connection holes 12 and the connecting piece 15 are water-bearing channels 14 educated. On the connection surface 11 can later the attachment element, so the actual sanitary fitting are placed, the controls and mixer elements, such as a thermostatic valve contains.

In 1 is an example of an open connection bore 12 shown. In a shell construction phase, in the beginning only the connection body 10 is inserted in a wall opening and at its connection piece 15 is connected to the water pipes, but are preferably all connection holes 12 through screw plug 20 closed to protect the inner channels 14 To provide pollution and to perform a pressure tightness test of the house installation can.

Like the sectional view in 2 shows have the screw plug 20 a threaded shoulder 22 and a broad head 21 that the connection holes 12 completely covered and can be equipped with a drive recess such as a hexagon socket. Under the head 21 is a sealing ring 23 inserted through which the environment of the connection bore 12 is sealed.

Instead of the screw plug 20 If necessary, a flushing pipe 30 be used, which is a covenant 32 that's upside down 21 of the screw plug 20 is comparable and also a threaded paragraph 31 which is in the internal thread 13 the connection hole 12 can be used.

The flushing pipe 30 can be inexpensively made of plastic. At the top, the flushing pipe is a cylindrical tube 34 It also has key surfaces on its outer circumference 36 can, as the perspective view in 3 shows.

The pipe 34 is designed so long that it protrudes in any case, even with large installation depths from a wall opening and possibly also from a sleeve-shaped protective element, in which the terminal body 10 is used to ensure that the connection body 10 when plastering and tiling remains undamaged and unpolluted.

At the upper end is a thread 35 provided, to which a test hose can be connected, which either leads to a test device in the pressure tightness test or is connected to a second flushing pipe. It creates a temporary connection between two connection holes, so as to be able to flush the water-conducting paths to the tapping point.
