Description

The invention relates in particular to a connection device for a radiator at a distance from each other parallel manifolds and between them extending heating tubes or a plate heater according to the preamble of the claim 1.

Radiators of the type mentioned, which are also referred to as conductor radiators, are used often to be used on the one hand as a heating device and on the other hand also visually enrich the environment. In such a case, such radiators also marketed as optically differently demanding products. Such radiators are usually provided with supply and return connections, which connect directly to the header pipes and are introduced into the wall. Radiators with a more sophisticated appearance are often used as radiators with a central connection trained, in which case a panel is used that the connection area the radiator along with all components, such as one Heating element electronics, an infrared remote control receiver unit and the like, hides behind. For such a radiator, a completely different design must be used in the lower area of the radiator, usually a tubular radiator to meet the assembly requirements for a center connection can.

Accordingly, different types of radiators were used as design radiators in the prior art manufactured and marketed, on the one hand for the simpler Embodiment, i.e. the embodiment that has no center connection and had no more complex equipment. On the other hand, the same size and Performance specifications also produced as high-quality designer radiators become.

Also for panel radiators, which are installed vertically in the bathroom area, for example corresponding problems can occur.

As a result, there was not only a more expensive and extensive type in the prior art manufacturing, but also additional storage, variety of parts, etc.

It is therefore the object of the present invention to provide a connection device and propose a corresponding radiator with it that is suitable to to reduce the manufacturing costs as well as the storage costs. In particular, a only type of radiator variable by a connection device according to the invention can be used, i.e. preferably by a series of radiator types at the same time another series of radiator types can be realized.

The above object is achieved by a connection device with those listed in claim 1 Features resolved. A radiator according to the invention is characterized by the features of claim 16 defined.

Appropriate embodiments of the objects according to the invention are described in Subclaims defined.

The advantages that can be achieved according to the invention are based on a connection device, the manifolds or manifolds of a heating cable register of a plate heater has assignable connection sections which are connected to the header pipes or

Bus line connections are attachable, being between the connection sections a connecting section extends, which can be fixed on the connecting sections is. In this case, connecting lines extend from the connecting section to the Forward and return of the heating system can be connected.

This configuration of the connection device makes it possible to use a normal one Convert radiators so that there is a radiator with center connection.

It should be noted that the connection device is both angled connection sections may have, but the radiator in question simply an extension of Can have manifolds, so that the connection sections directly in openings have the header pipes inserted or, in principle, a lower heating pipe can simply be sawn off or removed with the appropriate connection piece, threaded piece or the like and the connecting portion of the invention Connection device can equally be used here according to the invention to be brought.

In other words, the connection sections for connecting the connection section to the manifolds can have a wide variety of configurations, if only the connection of the connecting section of the connection device according to the invention allow. This means that the connection sections are in accordance with the task the present invention is very important, but they can be different Way. The same applies to the connecting cables of the Connecting section. These can also be diversified. It is also depends on whether a panel radiator or a tubular radiator is connected should.

An advantageous embodiment with features according to the invention results if the connecting section has a tolerance compensation section which is between a connection section or a manifold or a manifold of a heating plate and can be inserted into the connecting section. I.e. the tolerance compensation section can be designed as a line section which extends in the axial direction of the Extend or shorten the connecting section, so that, for example can be designed telescopically, or in connection with a holding arrangement the connecting section can be extended or shortened in the axial direction.

Such tolerance compensation sections can also be on both sides of the connecting section be arranged.

Another advantageous embodiment results when the connecting section and / or a connection section has a receptacle for a valve or the like. I.e. can simultaneously with the assembly of the connection device according to the invention also a valve or a thermostatic valve or the like for controlling the to be connected Radiator to be installed with. Of course, this can also be a remotely controllable one Act valve or the like. Any drainage plugs or the like can also here via corresponding recording devices simultaneously with the invention Connection device can be provided on a radiator by a standard radiator to be converted into a high quality radiator. The Valve receptacle provided in the course of the connection device according to the invention be, a line section from the main axial direction of extension of the connecting section runs out. The valve seat can be transverse to the main direction of extension extend so that the valve receptacle connects the line section with the connecting section at the end of the opposite end of the line section Flow end connects. In this way, a valve seat that together with the valve can have a considerable length in relation to the radiator surface, which extends between the manifolds, usually to the rear back to the wall of a building. The valve in question, or its The control knob will not protrude particularly far from the radiator under these circumstances or only protrude as far from a cover panel to be installed later, that it can be gripped comfortably, but in no way unsightly or obstructive protrudes.

The connection device according to the invention is particularly advantageous if the connecting section in the area of the junction of the connection lines to the heating system is divided in the axial direction. In such an embodiment it is possible to use a single pipe, which is divided to realize two lines, such that, for example a sheet is inserted into a tube, or the connecting section by means of an injection molding manufacturing method immediately equipped with appropriate lines becomes. On the other hand, it is also possible to drill holes in a metal rod to be introduced or in gears provided in a workpiece produced by injection molding to extend, to close or by milling, drilling or the like the like to the necessary lines for flow guidance for a pre and a To divide the return for the radiator.

The subdivision advantageously ends on the side assigned to the recording this beyond the mouths of the connecting lines in the connecting section. Only a single line needs to be fed to the valve, since the flow or the flow through the radiator can already be optimally controlled in this way can.

The meaning and purpose of the subdivision can also be seen in both connecting lines to the heating system a connection possibility to the lines of the connecting section to provide. On the other hand, since there is only one collector pipe on each Side, there should of course only be one line at a time, i.e. either the Forward or the return line to one of the connection ends of the connecting section be performed.

Of course, it is also possible to have more than just one valve seat in the connecting section to use. This can e.g. become interesting if there is also underfloor heating to be connected to the connection device according to the invention. In In this case, the connection device according to the invention can, for example, two more Have connecting lines, with a further Underfloor heating circuit a heating medium regulated via the additional valve holder or the valve located therein, can be supplied and via the further additional Connection line can be disposed of again. In this case, would the panel of the radiator to be installed later through two openings two valve control knobs or thermostat knobs or the like protrude to enable regulation.

The subdivision of the connecting section ends on that facing away from the receptacle Side in front of the tolerance compensation section but beyond the junctions. Here can a line can be closed, for example, by means of a plug or the like. It is also possible to solder, weld, glue an end piece into one of the cables or the like

In the simplest case, it is of course also possible to between the connecting section simply insert a separating section in the connecting lines in order to force the flow to set up. It is also possible to simply use two pipes that from the connection lines to the manifolds or to these Lead connecting sections. A particularly favorable embodiment results if each of the mouths is assigned two openings starting from the connecting section are, each of the openings is closable. In this way each of the connecting lines can be connected to each of the two overlapping lines be connected within the connecting section, so that the front and the Return from the heating system can be almost arbitrary and the radiator to be connected can later be adapted to the conditions that arise when installing the relevant radiator can be found. Depending on where the lead from the heating system should be introduced into the radiator, one of the Openings, for example with a bolt, a plug, a screw or the like. be added. Usually the pre-run will be regulated, i.e. the valve seat will be assigned to the flow from the heating system so that the intended Accordingly, openings are left open or closed.

On the other hand, if the connecting section is only a continuous open tube, a suitable guide body can be placed in the pipe near the connection lines to the heating system be pushed. This guide body can, for example, be a plastic injection molded part, a sheet metal or the like that provides the desired conduits. Naturally it is also possible to use an injection tool to create the appropriate cable routing inject directly into a pipe, which is an inexpensive way of manufacturing should represent.

The same applies if connections are also provided for underfloor heating should be. These can also be inserted with the appropriate cartridge Insert cable guides into a suitably designed guide section or generate in this by a plastic injection technique.

Advantageously, on both sides, but at least on one side of the connecting section Fasten the adaptation sections. These can be welded on, for example, soldered, glued, screwed or nippled. The adaption line sections can be provided to be uniform for different Radiator sizes trained connecting section to different sized radiators adapt. That is, a connection section is for a minimum radiator width of for example, 40 cm and can be made by appropriately long adapter line sections can also be adapted to radiators that are slightly or significantly wider. The tolerance compensation section can also be designed as an adaptation line section his. This can mean that the one assigned to the tolerance compensation section Adaptation line section can then be screwed sealingly to the connecting section, but is usually not weldable or the like.

The invention extends of course to a radiator, the two Has manifolds, which are spaced from each other, between the Collector tubes extend heating tubes, this radiator with a connection section is provided according to the invention or according to one of the subclaims.

1 shows an advantageous embodiment of a connection device with features shown according to the invention.

A connecting section 10 is provided here between two connecting sections 12, with connecting lines 14a, 14b extending from the connecting section 10 for connecting the connection device according to the invention to the line network Heating system are determined.

The connection sections 12 are intended to be connected to a manifold of a radiator, in particular a ladder-shaped tubular radiator (not shown) with a threaded section 12b to be screwed on. Sealing takes place via a sealing ring 12e, which is supported on the body of the connection section 12. At the bottom of the Body of the connection section 12 is a plug 12c with a screw nut trained cover 12d provided with the body of the connecting portion 12 can be connected via a seal 12f. A connecting piece 12a extends from the body 12 and serves to connect the connecting section 10th

Again, it should be noted that the connection section in different ways can be realized. This makes it possible to use the bottom heating tube on a ladder radiator saw off and the remaining stubs extending from the manifold to be used as connections for the connecting section 10. Of course, the headers can also be formed laterally with screw connections, for example around one Screw the socket like the socket 12a directly onto a manifold of a guide radiator to be able to.

Extend between the connecting section 10 and the connecting sections 12 Adaptation line sections 16, 18 connecting the connecting section 10 to different adjust wide radiators. The one adapter line section 18 can be in one Line section 24 of the connecting section 10, for example welded, soldered become. In principle, each is mechanically stable, temperature-resistant and liquid-tight Connection technology can be used to the adapter line section 18 on the Specify connection section 10. On the opposite side is the adapter line section 16 by means of a union nut 16a and a screw thread section 16b on the connecting section 10 also realized as a tolerance compensation section. While on the side of the connection piece 12a, the adapter line section 16 is brought into a press seal system is on the opposite Side a space between the end of the connecting portion 10 facing Adaptation line section 16 and the connecting section 10 are provided, which is variable without the connection becoming leaky. That is, manufacturing tolerances of the Radiators to be connected can be in the axial direction of the connecting section 10 be compensated for by the freedom provided here.

In this advantageous embodiment, the connecting section 10 has two line sections 32, 34 which overlap in the area of the connecting lines 14a, 14b. During the one line section 34, the return of the radiator here is assigned to the return 14b to the heating system, is the connection line 14a, which is assigned to the flow of the heating system, connected to line 32. In order to implement this flow pattern, there are connection openings 28a, b and 30a, b of the connecting lines 14a, 14b each have one, for example Grub screws 26 can be closed, which in the openings 28b to be closed and 30a closed. The resulting flow control can be the black Remove arrows. The heating medium is then in via the connecting line 14a the connecting line 32 inserted and via a line section 20, which from the Axial direction of the connecting section 10 runs out, introduced into a valve seat 22, into which a valve of conventional type 40 is screwed in a sealing manner. From there the heating medium via the connection section 24 into the adaptation line section 18 initiated and via the connection section 12 into one of the manifolds of the to be connected Radiator introduced. The heating medium flows from this manifold through the heating tubes (not shown) into the opposite manifold and from there via the connection section 12 shown here on the right and the adapter line section 16, the tolerance compensation section 16a, 16b in the line 34 of the Connection section 10 and from there through the opening 30b into the connecting line 14b from which the cooled heating medium is introduced into the piping of the heating system becomes.

To the desired forced guidance for the heating medium through the line section 32 to be set up, a plug 37 is to be fitted at one end of this line section screwed, soldered, glued or the like and opposite is between the Outer wall of the connecting section 10 and a partition 33 between the lines 32, 34 also a closure part 36 arranged liquid-tight. The locking parts 36, 37 are to be arranged for production reasons in order to set up the necessary flow guidance to be able to.

According to FIG. 2, the connecting lines 14a, 14b are opposite the illustration according to FIG. 1 reversed supply and return connections of the heating system assigned. Accordingly here the opening 30b is sealed by a closure 26 and the used one Heating medium flows through the opening 28 b in the return to the heating system. Vice versa 2 is the opening 30a through and heating medium from the flow of Heating system flows via the connecting line 14b into the line 32 and from there into the radiator.

If it is desired to insert a heating element in the radiator to be connected, it is possible to remove the plug portion 12c, 12d from the connection portion and in its place the flange and power supply section of an electrical To flange the heating element.

In Fig. 3, a connecting portion 10 is partly in a sectional view and partly in one Played front view. The connecting lines 14a, 14b are designed such that for example by means of union nuts on the supply and return of the heating system can be applied. The connecting line 20a, which from the axial direction of the Connection section 10 runs out, the connection between the line 32 according to 1 and 2 and the valve receptacle 22 are available.

3a, the connecting section is easily recognizable as an oval tube, which is surrounded by a pipe sleeve 42. In the oval connecting section the connecting lines 32, 34 are formed, which connect the connecting line 14b via the openings 30a, 30b are connected. The openings 30a, 30b can be partially threaded be designed to screw a closure into one of the openings 30a, b to be able to. Section B-B according to FIG. 3b shows a cross section of the connecting line 14b and shows that this also relates to the openings 30a, b as an oval tube is trained.

The cross section C-C according to FIG. 3c shows the cross-sectional shape of the connecting section 10 in the region of the main axial direction of extension of the connecting section outgoing line 20 or 20a.

According to FIG. 4, it can again be clearly seen that the line 34, which is the return is assigned by the radiator, towards the end of which by a conversion region 10a Connection section 10 is completed. The receiving space 40a of the valve seat 22 is open here, i.e. shown without valve.

According to the invention, it is thus possible to use a correspondingly designed radiator screw in formed as T-pieces connecting pieces 12 to which the connecting portion 10 can be applied according to the invention. The T-pieces or Of course to place connection sections 12 with connection sockets pointing inwards, in order to be able to attach the connecting section 10. The adaption line sections must be selected and arranged according to the size or width of the radiator.

The embodiment of a connection device 10 ′ shown in FIG. 5 with features according to the invention largely corresponds to the embodiments described above.

A major change is that between the connectors 12 and the connection section 10 a modification with regard to the adaptation line sections 16 ', 18' and the tolerance compensation sections 16a 'assigned to them also in the form of union nuts, which have a soft sealing screw connection available for tolerance compensation, can be seen. So here are both Provided ends of the connecting section 10 'receiving areas 16c, 24, in the adaptation line sections 16 ', 18' welded, hard soldered, glued in or otherwise how liquid-tight are used. At the respective ends of the adapter line sections 16 ', 18' are tolerance compensation sections 16a 'which are attached by means of threaded connections 12a 'are attached to the connection sections in a liquid-tight manner.

Here, too, the tolerance compensation sections 16a 'are designed as union nuts, to enable a soft sealing screw connection, which is via a compression of the sealing area 16b 'comes into being. A tolerance range is purely schematic 17 in the threaded connector of the connection section 12 on the left side according to FIG. 5 shown.

5 can also be designed such that again only one adapter line section in the form of section 16 'is provided is to adapt the device according to the invention to different radiator dimensions or radiator types while the other adapter line section 18 'only, as in the embodiment according to FIGS. 1 and 2, for Connection of the radiator to the device 10 'according to the invention is used.
