Description

The present invention relates to a modular floor heating distributor.

Underfloor heating distributors usually consist of two parts, a flow and a return line, which are installed at a certain height distance from each other. These distributor strands are manufactured as one-piece pipe strands or in a segment design, in which the individual segments are connected via a thread or bayonet joint ( EP 0 993 584 A1 . DE 196 08 781 A1 . EP 2 075 496 A1 . DE 20 2015 106 992 U1 . DE 20 2015 106 987 U1 ) or via pull rods ( DE 30 43 422 A1 . EP 1 798 485 A1 ) are connected to each other.

Due to the offset height of the flow and return lines, these known distributors traditionally require more space, so that significantly larger distribution cabinets are required for installation. In addition, these distributors have the disadvantage that the relatively rigid pipes have to be guided behind the lower branch to the upper branch when installing the underfloor heating, which in turn is associated with a relatively high outlay due to the narrow installation space. The distributors are designed so that they are suitable for connection to horizontal supply lines. Special angle sets are required for connection to vertical supply lines, which results in additional costs.

In contrast, it is the object of the present invention to provide an underfloor heating distributor which has a compact and modular construction and therefore requires as little space as possible in the distribution cabinet.

This object is achieved according to the invention by a modular floor heating distributor with the features of claim 1.

Due to its small space requirement, the distributor according to the invention is ideally suited for installation in pre-assembled distribution cabinets, which are delivered to the construction site fully equipped (with distributor and control). Depending on the number of heating circuits, the distributor can be set up with a corresponding number of distributor modules. In the modules, the supply channels preferably run at the rear and the return channels at the front in order to form a rear supply line and a front return line.

A special space-saving arrangement is obtained if the flow connection and the flow shut-off spindle of each distributor module are staggered with respect to the return connection and the return shut-off valve of the distribution module in the longitudinal direction of the module, i.e. offset by about half the heating circuit distance.

In particularly preferred embodiments of the invention it is provided that the rear flow connections extend further down than the front return connections and the return connections are inclined in the direction of the respective flow connection. Due to the lowered flow connections, these are easily accessible during assembly. Due to the slightly backward inclined return connection, the pipe end of a heating circuit pipe laid in the floor can be optimally inserted due to the corner bend of the pipe end. Overall, the best possible installation comfort is thus achieved with the smallest space requirement.

The connection module can advantageously have a filling and emptying valve for filling and emptying the flow line and / or the end module can have a filling and emptying valve for filling and emptying the return line.

Connection tube pieces for a feed line are particularly preferably connected to the open and return channels of the connection module at the ends. By using a straight or angled connecting pipe section, the distributor can be connected to both vertical and horizontal supply lines without accessories. This makes it possible to produce a relatively short distributor with a variable connection.

To vent the flow and return lines, the end module can have a flow vent valve arranged in the flow channel and a return vent valve arranged in the flow channel.

The connection and end modules can particularly preferably be arranged by rotating through 180 ° on one or on the other end-side distributor module. Thanks to the modular design, the connection module can then be installed on the left and right by moving the connection and end modules without the need for additional components.

Preferably, the connection module and the end module can each be fastened to a horizontal leg of a holding bracket running transversely to the longitudinal axis of the module in positions of different depth to the other leg of the holding bracket. As a result, the wall distance (depth to the wall) of the distributor can be set variably, in particular as large as possible, so that there is greater ease of installation. For example, the connection module and the end module can each be slidably guided and ascertainable on the horizontal leg of the holding bracket between a front and a rear end position. The horizontal leg of the bracket can advantageously have a horizontal elongated hole, which is penetrated by a bolt of the connection module or the end module.

The feed channel, the return channel, the feed connection, the return connection and receiving openings for the feed shut-off spindle and the return shut-off valve are very particularly preferably formed or shaped on a module housing. The separation of the two channels, as well as a rectangular enclosure of the two channels, creates corresponding air chambers which have a certain thermal insulation effect. This can be particularly advantageous in cooling applications due to the possible formation of dripping water. The module housings are preferably plastic injection molded parts.

Further advantages and advantageous configurations of the subject matter of the invention can be found in the description, the drawing and the claims. Likewise, the features mentioned above and those listed further can be used individually or in combination in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

the underfloor heating distributor according to the invention mounted on a wall, each with a minimum and a maximum distance from the wall.

The in Fig. 1a, 1b Floor heating distributor shown (hereinafter called distributor) 1 is used for heat distribution of an underfloor heating. The individual heating circuits of the underfloor heating system are each connected with their flow to a rear flow line and with their return flow to a front return line of the underfloor heating distributor 1, the flow line and the return line running horizontally and parallel to one another.

The distributor 1 is modular of several (in Fig. 1 four) distributor modules 2, a connection module 3 and an end module 4 are formed, which are lined up closely in the longitudinal direction 5 of the module. The distributor modules 2 are arranged between the connection module 3 and the end module 4 and braced against one another by means of two threaded rods 6 which pass through the distributor modules 2.

As in Fig. 2a, 2b shown, the distributor modules 2 each have a rear flow channel 7 that is open on both sides in the longitudinal direction 5 of the module , a front return channel 8 that is open on both sides in the longitudinal direction 5 of the module, as well as a rear flow connection 9 that goes down from the flow channel 7 and one that goes downward from the return channel 8 Return connection 10 on the underside of the distribution module 2 and a flow shut-off spindle 11 for shutting off the flow connection 9 and a return shut-off valve 12 for shutting off the return connection 10 on the top of the distribution module 2. The flow connection 9 and the flow shut-off spindle 11 of each distributor module 2 are offset with respect to the return connection 10 and the return shut-off valve 12 of the distribution module 2 in the longitudinal direction 5 of the module.

The connection module 3 is connected to the in Fig. 1 extreme left distributor module 2 connected and, analogously to the distributor module 2, has a flow channel 7 that is open on both sides in the longitudinal direction 5 of the module, an angled return channel 8 that is open on both sides, and on the top of the connection module 3 a shut-off shut-off valve 13 attached to the flow channel 7 in the form of a KFE cock (boiler fill and drain valve) . The flow channel 7 has a connection in the form of a straight connection pipe section 14 and the return channel 8 has a connection connection in the form of an angled connection pipe section 15 , so that the distributor 1 can be connected to horizontal supply lines. The connecting pipe pieces 14, 15 are tightly inserted into the horizontally open, end-side opening 16 of the flow channel 7 and into the vertically open, end-side opening 17 of the return channel 8 and each secured by means of a securing clip 18 .

The end module 4 is connected to the in Fig. 1 Extremely right distributor module 2 is connected and has a flow channel 19 open on one side in the longitudinal direction 5 of the module, a return channel 20 open on one side in the longitudinal direction 5 of the module and on the bottom of the end module 4 a shut-off valve 21 in the form of a fill and drain valve that blocks the return channel 20 and on the top in the flow channel 19 arranged flow vent valve 22 and a return vent valve 23 arranged in the return duct 20.

The modules 2, 3, 4 form with their flow channels 7, 19 a continuous, rear flow line and with their return channels 8, 20 a continuous, front return line.

The distributor 1 can be modularly expanded as desired. For this purpose, the end module 4 is disassembled, and two threaded bolts are screwed onto the threaded rods 6 to extend them, so that a corresponding number of distributor modules 2 can also be installed.

In Fig. 3 a connection connection in the form of an angled connection pipe piece 15 is connected to the flow channel 7 of the connection module 3 and a connection connection in the form of a straight connection pipe piece 14 to the return channel 8, so that the distributor 1 can be connected to vertical supply lines.

At the in Fig. 4a, 4b Distributors 1 shown are the connection and end modules 3, 4 compared to Fig. 1 arranged reversed, the end module 4 is designed without a shut-off valve. Due to the modular structure, the connection module 3 can therefore be mounted both on the left and on the right, without additional components being required for this.

The flow channel 7, the return channel 8, the flow connection 9, the return connection 10 and receiving openings for the flow shut-off spindle 11 and the return shut-off valve 12 are formed by a module housing 24 made of plastic, the flow channel 7 and the return channel 8 being thermally insulated from one another by housing chambers.

As in Fig. 2b shown, the flow shut-off spindle 11 has a flow meter 25 and is designed such that no additional screw-in body is necessary as a connecting thread to the distributor 1. The flow shut-off spindle 11 is inserted into a housing opening of the module housing 24 and sealed therein by sealing rings and held on the module housing 24 by a securing clip 26 . In the event of service, the supply shut-off spindle 11 can be removed relatively easily by pulling the securing clip 26.

As especially in FIGS. 4a, 4b shown, the distributor 1 is fastened to a wall 28 by means of two brackets 27 . The brackets 27 are formed as a rectangular bracket with a vertical leg 27a for attachment to the wall and a horizontal leg 27b . A horizontal elongated hole 29 runs in the horizontal leg 27b and is penetrated by a threaded bolt 30 of the connection or end module 3, 4. The threaded bolt 30 can be moved in the elongated hole 29 between a front and a rear end position and screwed tight in the desired position, so that the distance from the wall of the distributor 1 can be variably adjusted.

The Fig. 5a, 5b show the manifold 1 mounted on the wall 28 with different wall clearances, namely in Fig. 5a with minimal wall clearance and in Fig. 5 with maximum wall distance.
