Description

The invention relates to a connection block for sanitary fittings.

It is known that one uses for the assembly of sanitary fittings, especially of complicated sanitary fittings, terminal blocks. The connection blocks are connected to the pipes of the domestic installation, both with the supply lines and with the discharges. The connection blocks themselves have channels that open out in, for example, a flat surface. The sanitary fitting is then connected to the terminal block in such a way that the mouths of the channels communicate with the inlets in the sanitary fitting and the outlets from the sanitary fitting. This division has the advantage that the sanitary fittings need to be mounted only after completion of the pipeline network. In addition, it is possible with appropriate design to connect different sanitary fittings with always the same terminal blocks.

In a known terminal block of this type ( DE 19856157 ), the pipes of the domestic installation and leading to a water outlet pipes are screwed to screw connections, each to 90 ° offset on the outer sides of the terminal block are arranged. The installation of the sanitary fitting happens from the front of the wall, ie perpendicular to the plane of the wall.

In a similar arrangement, the sanitary fitting is attached to the front of the terminal block using spacer tubes. DE 19525358 ).

There is already known an installation device with a terminal block, which is attached to a wall. On its front side facing away from the wall, it has a socket into which a plug-in nipple of a valve can be inserted ( DE 3807844 A1 ). The socket is only connected to a supply line.

Also known are fittings that contain electronic components for controlling the valves and / or for monitoring the function of the valves. These electronic components are often housed in a separate box, which also contains the electrical components, such as drives.

The invention is based on the object to provide a way to make connections between a domestic installation and even complicated fittings without operator error and without additional work.

To solve this problem, the invention proposes a terminal block for sanitary fittings with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.

After completion of the installation using the terminal block, the sanitary fitting can be parallel to the surface of the wall with the terminal block be connected by plugging. This makes it possible to achieve a low height.

For connection between the terminal block and the sanitary fitting serve plug-in connection means, which cause a simple mechanical insertion and a hydraulic connection between the two parts and include on the side of the terminal block sockets.

The connections for the lines are arranged on the side facing away from the sanitary fitting of the terminal block.

In particular, the invention is applicable to a terminal block with which the sanitary fitting is connected in a direction parallel to the wall surface.

Such terminal blocks are often formed in such a way that the axis of the connections to the terminal block is parallel to the wall surface.

In a further development of the invention can be provided that the connector means have plug-in nipple as part of the sanitary fitting for insertion into the sockets.

It may be provided in a development that the plug-in nipple in its end region have a seal, in particular a circumferential seal in the form of an O-ring, which cooperates with the wall of the socket for sealing. Thus, the point at which is sealed, arranged at a distance from the outside of the terminal block or the sanitary fitting.

After the connection has been made, a mechanical protection against the release of the plug-in connection must be carried out. This can be done, for example, by securing means acting transversely to the direction of insertion.

For example, for this purpose, bolts or pins are used, which are inserted transversely to the direction of insertion between the sanitary fitting and the terminal block in this and set at least one of the nipple form-fitting manner in the terminal block. This attachment between the bolt and the plug-in nipple can also advantageously take place in the region between the outside of the connection block and the sealing region of the plug-in nipple.

In particular, the bolt may be a partially threaded bolt, which is thus screwed into the terminal block and fixed by a threaded portion. Also, this bolt can be screwed from the front into the terminal block and removed from it.

The mains networks of a domestic installation must be flushed out before commissioning in order to flush out any dirt or chips generated during the laying of the cables from the pipes. This is preferably done before the complicated sanitary fittings are installed.

For this purpose, it has been proposed to attach to a completely installed terminal block instead of the sanitary fitting a flushing block that can connect the connected to the terminal block lines through internal channels. After successful rinsing, this rinse block is removed again. The flushing block, as well as later the sanitary fitting from the front, so perpendicular to the surface The wall in front of which the fitting is attached to the terminal block created and fixed there.

To solve this further problem can be provided in a further development of the invention that the terminal block has a purge line, which is formed in the terminal block as a channel and connects the input terminals to the output terminals. This purge line is inventively designed such that in the production of the connector between the terminal block and the sanitary fitting, the purge line is disabled.

The fitter does not need to deal with it after he has connected the lines to the terminal block, subsequently attach a flushing block, but he can use the purge line contained in the terminal block for flushing the lines. An elaborate flushing block is no longer necessary. The fitting-side openings can be closed by simple plugs. This design makes it possible to perform a flushing and later a check for leaks of the pipe network even if there is no space for the attachment of a flushing block, for example, because the sanitary fitting is not connected from the front to the terminal block.

It can be provided in a development that the flushing line is in communication with the sockets in the area between the outside of the terminal block and the sealing area. By making the connector so that the purge line is put out of action, without their mouth is sealed directly into the socket.

In a further development of the invention can be provided that the flushing line passes through the sockets eccentrically. It is possible that the purge line is formed as a single bore.

In a further development of the invention can be provided that the terminal block for each of the two inlets has a Vorabsperrung, which can be operated in particular also from the front.

It can also be provided that the connection block has a sieve for each of the two inlets, and this sieve can also be used with advantage transversely to the direction of connection between the sanitary fitting and the connection block.

It has proven to be particularly useful to accommodate this sieve in the Vorabsperrung itself, so that it can always be removed and cleaned when the Vorabsperrung is turned on.

The FIG. 1 shows in a plan view of an open box in which a sanitary fitting 1 is housed. This box with the sanitary fitting 1 is attached to a wall, so that the viewing direction of FIG. 1 directed to the wall. The sanitary fitting contains drives and controls, which are not discussed in detail. The sanitary fitting 1 includes a mixing valve 2, in which a quantity control is housed. The side of the mixing valve 2, a plurality of exhaust valves 3 is flanged, which are supplied with mixed water from the mixing valve 2. The exhaust valves 3 are electrically controlled. The required electronics are housed in components within the box.

From the box protrude at the in FIG. 1 bottom side several nipple 4 out. These nipple 4 serve to connect the sanitary fitting with water pipes of the house installation. All plug nipple 4, in the illustrated embodiment, the same size and are otherwise identical. They protrude from the flat bottom of the box vertically and all end in the same plane.

The FIG. 2 shows a connection block, with the help of the pipes of the domestic installation to be connected to the sanitary fitting 1 in the box. The FIG. 2 shows a view from the same direction as the FIG. 1 , Each plug nipple 4 of the sanitary fitting is associated with a socket 5, which in the state in FIG. 2 is shown closed with a plug 6. At the in FIG. 2 left end, the terminal block has a broadening. There two Vorabsperrungen 7 are arranged, which can be rotated with a key. The two left in FIG. 2 see through the terminal block leading passages are intended for the supply, while the other passages are determined by the terminal block for the lines leading to the consumers. This is indicated by the arrow marks on the top of the terminal block.

The FIG. 3 now shows a section through the terminal block in a plane parallel to the plane of the drawing FIG. 2 runs. For the supply of hot and cold water, there are on the side facing away from the sanitary fitting two connections 8, which are each connected to a passage through the terminal block. The passage ends in each case in a socket 5. Also in the representation of FIG. 3 the passages on the sanitary fitting facing side are closed by a plug 6.

The same connections 9 gives this for the leading of the plumbing faucet lines, whereby these terminals 9 are connected rectilinearly with the sockets 5.

Through the connection block performs a purge line 10 in the form of a channel. This channel is designed as a bore, by the one Front side passes to the other end side and is completed at both ends with a stopper 11. It is also conceivable to form this channel as a blind hole, so that only one side of a plug 11 is required.

How to cut the FIG. 3 can remove, the purge line 10 is connected to all sockets.

The terminal block proposed by the invention is used as follows. First, at the point where the sanitary fitting is to be attached, the terminal block in the state as the FIGS. 2 and 3 show connected with the pipes of the house installation. To the terminals 8 so the hot or cold water approaching line is connected, and at the terminals 9, the leading to the consumers lines are connected, so for example, the line to a shower, to a tub inlet or the like.

If, for example, then the line for the cold water is provided with water, this water can pass through the purge line 10 through the terminal block to all outlets. This makes it possible to flush the lines. Similarly, it is also possible to perform a pressure test of pipes.

When this action has been taken, the plugs 6 are removed and the box with the sanitary fitting in a direction parallel to the wall with the connection nipples 4 advances toward the terminal block, so that the nipple 4 engage in the sockets 5.

The FIG. 4 shows in enlarged scale a plan view of the left end portion of the terminal block. At this point is access to the already mentioned Vorabsperrung 7 possible. This access takes place from the front side of the connection block, ie from a direction perpendicular to the wall surface and thus also perpendicular to the connection direction between the sanitary fitting and the connection block.

The FIG. 5 shows a cross section through the terminal block in the amount of a socket for a plug nipple of an outlet valve 3. The socket 5 is still closed with the plug 6. Trained as a bore purge line 10 extends at the edge of the socket 5 in a region of the socket 5, where the diameter is slightly larger than in the end of the socket. The point where the purge line 10 passes through the sockets 5, lies in the axial direction of the socket 5 approximately in the middle, between the part where the thread for the plug 6 is present, and the smaller diameter end portion.

The state of the connection between the sanitary fitting and the terminal block at this point shows the FIG. 8 to which reference is now made. The plug nipple 4 is now plugged into the socket 5 until its free end 12 comes to bear against the transition between the socket 5 and the terminal 9. The plug-in nipple 4 has in its end region one or two circumferential seals 13, which serve for sealing engagement with the end region of the wall of the socket 5. The seal between the socket 5 and the nipple 4 thus takes place in the end region of the plug nipple 4. The point where the purge line 10 is in communication with the sockets 5, is closer to the sanitary fitting 1 facing outside 14 of the terminal block. As a result, the flushing line 10 is disabled as soon as the nipple 4 are inserted into the sockets 5. The mouth of the purge line 10 in each of the sockets 5 need not be self-sealed.

How to cut the FIG. 8 can also be seen, the plug-in nipple 4 at exactly the point where the purge line 10 opens into the socket 5, a circumferential groove 15. This circumferential groove 15 is also in the view of FIG. 1 but its meaning is only clear here. To explain this in more detail, is now on the FIG. 6 Referenced a section through the in FIG. 4 shown end of the terminal block shows. To lock the terminal block relative to the sanitary fitting are pins 17, which in turn are screwed from the top of the terminal block, ie perpendicular to the wall surface, in the terminal block. This pin engages in the aforementioned groove 15 of the nipple 4 a. The pin 17 has in the region below its head 18 on a threaded portion 19, with which it is screwed. The front portion of the pin 17 may be formed smooth surface. He is in the aforementioned groove 15 at. In this way, by using one or two pins 17, a lock between the sanitary fitting and the terminal block. This lock is form-fitting.

Now to the FIG. 7 , Here is the section through the terminal block in the amount of a passage for a supply line laid. Again, the plug nipple 4 is plugged into the socket 5. The connection between the connection 8 for a supply line and the socket 5 passes through a channel 20 in the form of a smooth-surfaced bore, which is penetrated by the Vorabsperrung 7. The Vorabsperrung includes a hub 21 to which a cylindrical sleeve 22 is rotatably connected. The cylindrical sleeve 22 has a closed bottom 23. The cylindrical sleeve contains in its wall two openings 24 which coincide with the contour of the channel 20. In the in FIG. 7 illustrated position, these openings 24 are aligned with the channel 20, so that the flow from the port 8 in the nipple 4 is unhindered. On the other hand, if the preliminary shut-off 7 is turned around the axle by means of the hub 21 the sleeve 22 by 90 °, the two openings 24 are transverse to the axis of the channel 20 and block the passage.

In the sleeve 22, a mounted in the hub 21 insert is arranged, which has a sealed head 25. At the head 25, a screen 26 is attached, which extends to the bottom 23. This trained as Leporello sieve 26 is folded and thus offers large flow areas and plenty of space for dirt deposition. It is therefore repeatedly flowed through by the water. If the Vorabsperrung actuated, that is, the passage closed by the channel 20 by turning the Vorabsperrung, the screen 26 can be removed and cleaned.

Also in the section of the FIG. 7 is the groove 15 of the plug 4 can be seen.

How to get the top view of the FIG. 2 can take, there are three such pin 17, each with a head 18th
