Description

[0001] The present invention relates to a mounting kit for a module on a buffer storage tank. A buffer storage tank serves to store warm heating water, usually in a temperature stratified system. Here, "heating water" refers to water that circulates in a closed loop and is sometimes treated with additives to minimize corrosion. To charge the buffer storage tank, warm heating water is typically introduced into the upper section of the tank in a first circuit. The thermal energy stored in the buffer storage tank is utilized by means of a second circuit, in which heating water is typically drawn from the highest point of the tank and fed to a heat sink. The cooled water is then returned to the buffer storage tank at the lower section, depending on the temperature.The cooled water is drawn off from the bottom of the buffer tank and used for heating, before being fed back into the top of the buffer tank. Such buffer tanks are commonly used in residential buildings.

[0002] The buffer storage tank for heating comprises a tank and surrounding thermal insulation, which has several openings, each providing access to a fitting attached to the tank. This fitting serves to connect to the inside of the tank. The fitting does not necessarily have to communicate with the inside of the tank. Rather, due to the various connection and application possibilities of the buffer storage tank, more fittings are typically provided than are required for its operation. These are at least sealed by a sealing plug.

[0003] The hot water stored in the heating buffer tank is sometimes also used in a fresh water station to heat the hot water drawn from the heating buffer tank with cold water supplied to the fresh water station. This heated water is then available for consumption. The fresh water station has inlet and outlet connections that are connected to corresponding inlet and outlet connections of the tank. The fresh water station typically has additional fresh water inlet and outlet connections for the potable water to be heated within it.

[0004] Such a fresh water station is an example of a module that is to be connected to the heating buffer storage tank in terms of flow and / or installation as part of the installation of a heating system.

[0005] Such an installation is problematic not only because of the insulation provided on the tank, which does not offer a secure attachment point for mounting another module. If the module incorporates a fresh water station, there is also a need to connect the tank's connections to the fresh water station's connections as economically as possible, ideally with the connections lying on the same plane. The connections on the tank are typically arranged strictly vertically, one above the other.

[0006] The present invention addresses the problem of simplifying and improving the mounting of a module on a heating buffer storage tank.

[0007] In this regard, the present invention proposes a mounting set comprising a mounting plate and a fastening element. The fastening element can be connected to the port of the buffer storage tank, in particular by screwing it in place. The port on the buffer storage tank can have an internal or external thread. The fastening element is designed to be preferably sealed when screwed to the port of the buffer storage tank. A fastening rod, preferably in the form of a threaded rod, projects from the fastening element and is to be connected to the mounting plate. The mounting plate also has functional surfaces selected for attachment to or with the module.

[0008] The mounting plate is preferably made of sheet metal. It preferably has at least one mounting hole through which the fastening rod or threaded rod can pass. In the case of a threaded rod, the rod carries a fastening nut and a lock nut, which clamp the mounting plate between them. The lock nut is located between the fastening nut and the fastening element. One end of the fastening rod is typically received in and connected to the fastening element. The fastening nut is located at the other end.

[0009] In addition to the mounting hole through which the mounting rod passes, the mounting plate can have several mounting holes, preferably designed as elongated slots. These mounting holes allow the mounting plate to be attached to a wall or other object, for example. Thus, the mounting kit is not only suitable for attaching the module to a buffer storage tank. Rather, the corresponding module can be attached to various objects or building components using the mounting kit. With regard to screwing the mounting plate to a wall, the mounting plate has at least two elongated mounting holes, one of which extends transversely (i.e., horizontally when the buffer storage tank is in place), and the other extending longitudinally along the mounting plate and then vertically. This allows for the compensation of certain inaccuracies in the wall-side attachment.For wall-side mounting, for example, holes are drilled in the wall for the screws that pass through the various mounting holes.

[0010] According to a preferred embodiment of the present invention, the functional surfaces are formed at a free, end-face end of the elongated mounting plate by retaining projections that are spaced transversely apart from one another. These retaining projections are usually identical and, particularly preferably to increase the rigidity of the mounting plate, are formed at the free ends of the legs of a U-shaped cross-sectional profile made of sheet metal. The retaining projections are located in line with the corresponding legs.

[0011] According to a preferred embodiment of the present invention, the mounting set has a mounting plate, which is generally associated with the module and preferably factory-attached to it. This mounting plate is designed to accommodate the functional surfaces, in particular the retaining projections. The mounting plate not only has a retaining opening, but also a receiving opening for receiving the free end of the mounting rod. This allows the mounting plate to be laid flat against the mounting plate, thereby facilitating a secure attachment of the module to the heating buffer tank.

[0012] According to a preferred embodiment of the present invention, the retaining opening has a significantly larger width in a direction transverse to the longitudinal direction of the mounting plate than the transverse spacing of the retaining projections. This makes it possible, during the assembly of the module, to displace the mounting plate transversely, i.e., horizontally, relative to the heating buffer tank, so that one, preferably two, nozzles formed on the module for guiding the water lie in a single vertical plane with corresponding nozzles of the heating buffer tank and thus "align" within the meaning of the present description.

[0013] Specifically for mounting the module on an object other than the heating buffer tank, the mounting plate features several receiving openings that align with the mounting holes provided on the base plate. This ensures a flush contact between the mounting plate and the base plate in every installation.

[0014] Particularly when mounting the module on the buffer storage tank, the position of at least one connection on the fresh water station and a corresponding connection on the buffer storage tank is fixed due to the design. With this in mind, a preferred embodiment of the present invention proposes providing the mounting plate with a retaining ridge. This ridge typically extends longitudinally along the mounting plate and preferably projects from one of the legs of the cross-sectional profile, i.e., from the end face of the corresponding leg. The mounting plate has a retaining slot that is adapted to receive the retaining ridge. With proper alignment of the respective connections of the module and the buffer storage tank, the retaining ridge engages in the retaining slot with minimal play.In other words, the positive locking mechanism between the retaining ridge and the retaining slot aligns the respective assigned nozzles of the heating buffer tank and module in the aforementioned vertical plane, thus simplifying the connection of the nozzles via piping in between.

[0015] According to its subsidiary aspect, the present invention proposes a heating buffer storage tank with a fresh water station arranged thereon, which is connected to the heating buffer storage tank via the previously presented mounting set.

[0016] Further details and advantages of the following invention will become apparent from the following description of an exemplary embodiment in conjunction with the drawing.

[0017] This shows: Figure 1 is a top view of a heating buffer storage tank; Figure 2 is a perspective exploded view of part of the heating buffer storage tank according to Figure 1with an embodiment of a mounting set and a module in the form of a fresh water station and Figure 3 a top view of the mounting plate of the module according to Figure 2 .

[0018] In the figures, reference numeral 10 denotes a heating buffer storage tank comprising a container 11 and thermal insulation 12. The thermal insulation 12 has several openings 13 that allow external access to nozzles 14, of which in Figure 1 Spigots 14a and 14b are used as inlet and outlet supports and are connected to piping, and from which in Figure 2 Another nozzle is marked with reference number 14c, which will be discussed further below. How Figure 2 To clarify, the nozzles 14 are each connected to the container 11. In the present case, the nozzles 14 are each in fluid contact with the interior of the container 11.

[0019] The nozzles 14 of the heating buffer storage tank 10, which do not serve to guide the flow, remain fluid-tight sealed with plugs that are usually provided by the factory.

[0020] Reference numeral 20 indicates in Figure 2 A module in the form of a fresh water station, which typically includes at least a heat exchanger, a pump, and a control unit. The fresh water station 20 is also surrounded by thermal insulation 21.

[0021] A mounting plate 22 is located on the rear of the fresh water station 20. At opposite ends, i.e., on the top of the fresh water station 20, the thermal insulation 21 is overlaid by the station inlet nozzle 23 and the fresh water outlet nozzle 24. Corresponding nozzles provided on the underside of the fresh water station are located in Figure 2 not recognizable.

[0022] Reference numeral 30 identifies a mounting set with a mounting plate 31, which is formed from a bent sheet metal with a U-shaped cross-sectional profile having opposing legs 310 and a base 311 connecting them. The base 311 has a central, usually round, mounting bore 312 and upper and lower mounting bores, each designed as an elongated hole 313.

[0023] The upper, end face of the U-profile is overlaid by functional surfaces 320, which are formed by retaining projections 321, which are arranged in extension of each individual leg 310 and which are recessed relative to a mounting surface 330 of the mounting plate 31 facing the heating buffer storage tank 10.

[0024] Functional surfaces 320a, extending parallel to the mounting surface, are therefore parallel to the plane containing the mounting surface 330, but set back from it. The free, upper ends of the legs 310 form functional surfaces 320b extending perpendicular to it. The retaining projections 321 have a transverse spacing that is determined by the width b of the mounting plate 31.

[0025] The mounting set 30 further comprises a fastening element designated by reference numeral 32, which in this case is designed as a plug with an external thread to which a hexagon is attached. The fastening element 32 is connected to a fastening rod in the form of a threaded rod 33, the free end of which can be screwed onto a fastening nut 34. Reference numeral 35 designates a lock nut that is screwed onto the threaded rod 33.

[0026] How Figure 3To illustrate, the mounting plate 22 has a retaining opening 220 in its upper area, the width of which B (see Figure 2 ), is significantly larger than the width b of the mounting plate 31. Below this retaining opening 220 is a receiving opening 221, which is designed to receive the free end of the threaded rod 33 and the fastening nut 34.

[0027] In Figure 2 or 3, there is another retaining opening 220 below it, and yet another retaining opening 220 at the lower end of the mounting plate 31. Between the two lower retaining openings 220 are vertically extending retaining slots 222. Each retaining opening 220 can also serve as a receiving opening 221.

[0028] Each of the legs 310 has a retaining ridge 340 projecting from the end face of these retaining slots 222. The retaining ridge 340 and the associated retaining slot 222 are dimensionally closely matched, both vertically and, in particular, horizontally.

[0029] The module 20 is mounted to the heating buffer storage tank 10 as follows: First, a factory-installed sealing plug is unscrewed from the additional port 14c. Then, the fastening element 32 is screwed into the additional port 14c with a seal. The threaded rod 33 is usually already inside the fastening element 32 and thus firmly connected.

[0030] Then the threaded rod 33 is inserted into the mounting bore 312, and the mounting plate 31 is screwed against the lock nut 35 via the fastening nut 34 and connected to the fastening element 32 in a rotationally secure manner.

[0031] The module 20 is then suspended. For this purpose, the retaining projections 321 are inserted from below into the upper retaining opening 220. The fresh water station 20 is then aligned by sliding it transversely to the longitudinal extent of the mounting plate 31, so that the station inlet nozzle 23 is flush with the upper outlet nozzle 14b. A further station outlet nozzle, also provided on the underside of the fresh water station 20 and aligned with the station inlet nozzle 23, is then aligned with the inlet nozzle 14a of the heating buffer storage tank 10. "Alignment" in this context means that at least the central longitudinal axes of the corresponding nozzles 23 and 14b intersect at a single point.

[0032] With this alignment, the retaining ridges 340 also engage in their corresponding retaining slots 222. Thus, the fresh water station 20 is mounted in the correct alignment relative to the heating buffer tank 10. No further measures are required to secure or mount the station 20 to the heating buffer tank 10. After the station 20 has been properly aligned with the heating buffer tank 10, the ports 14a and 14b can be connected to the corresponding ports 23 of the fresh water station, and the other ports 24 of the station 20 can also be connected to the rest of the installation.
