HEATING COMPOSITION

The present invention relates to a heating assembly according to the preamble of the single main claim.

Such a heating assembly is known from publication EP 1 275 910, wherein the heating assembly 10 comprises a boiler unit and a distribution unit. The distribution unit is provided with conductors, which serve to guide the boiler unit during placement. The problem here is that the boiler unit still needs to be connected to the pipes when it is installed. To effect the connection of the boiler unit, a person is required who has experience in connecting such a heating assembly. If the connections are not good, they will leak and that will cause problems. The present invention has for its object to obviate or at least to reduce the disadvantages of the known art, by providing a heating assembly as defined in the appended claims, in particular the independent claims.

It is further noted that a boiler is deemed to be installed when a new building is delivered. In view of the time-consuming work of a fitter to install such a boiler, it often happens that a boiler was installed long before delivery. This gives thieves the opportunity to steal the boiler, which certainly represents a considerable value. A solution is thus desirable in order to keep the time between the installation of a boiler and the delivery of a new building as short as possible.

To this end, a heating assembly according to the invention is provided, with the known and moreover also the properties that differ from the known art according to the characterizing part of the single independent claim. An advantage hereof is that the active unit can easily be brought to the coupling position, wherein parts of the coupling elements are at least well aligned. When the active unit is in the coupling position, the connections between the pipes and the pipe connections can also preferably also be established, although this establishment of the connections is not required. An additional operation is thus not necessarily required to establish all connections, since these can be established simultaneously with the positioning of the active unit. This makes it easy to replace the entire active part, in the event of a defect and / or malfunction or when a new version is available. It is not necessary to have a specialist come, but the replacement can be done by any person. A business advantage of the invention is that after an operating time, eg of five years, the active part of the assembly can easily be exchanged for a cleaned unit, thus eliminating the necessarily expensive major maintenance of the active unit on site. The repair and / or maintenance of the removable active unit can then take place at a different location and time. The property "connectable" in this description implies that the active unit is also removable in the reverse way, or that the passive unit and the active unit are not permanently connected. The active part is an indication for an assembly of components or parts, optionally in one or more than one module, of a boiler, and preferably those parts and components that are susceptible to wear, replacement or at least regular maintenance.

Such an assembly can be exchanged without hindrance to users or residents of a building, so that repair or maintenance can be carried out at a remote workplace, for example. The passive part remains mounted (semipermanently on (a wall of) the building. It is precisely this passive part that can be mounted in advance or installed in new construction, so that the active part can only be mounted easily shortly before delivery, and the time between assembly of (the active part of) the boiler and delivery can be kept as short as possible.

The invention has various preferred embodiments which are defined in the dependent claims and / or appear from the following description of some such embodiments. The advantages and the inventive features of the invention in all its aspects, including the measures defined in the dependent claims, are by no means limited to the above and / or below mentioned considerations.

Preferably, the removable active unit is a heating unit with an integrated electronic module 25 for controlling the removable active unit. By designing the heating unit and the electronic module as a whole, it is relatively easy to replace the entire active unit in the event of a defect and / or malfunction. It is not necessary to search for which defect and / or malfunction has occurred.

More preferably, the heating unit and the electronic module can be connected separately. An advantage of this is that if it is known where a malfunction and / or malfunction has occurred, only that part will be replaced.

This saves costs by only replacing the necessary and not the entire removable active unit. Furthermore, an electronics module is easier to handle, so that it will be replaced more quickly.

In addition or as an alternative, the (or one) electronics module is integrated in the passive unit. One reason for mounting the electronics module there may be that the electronics module is a stable factor overall and has rare defects and / or malfunctions. By then integrating the module into the passive unit, it will be placed at the installation and require virtually no further attention.

In a further embodiment the heating unit comprises different modules, each of which can be removed separately. If a defect and / or malfunction now occurs, not the entire boiler will be replaced, but only the module with a malfunction and / or malfunction. It is possible that most sensitive components, such as heat exchanger, fan and pump, are arranged in the detachable active unit in this way.

It is advantageous here that the weight of the removable active unit is at most equal to the legally permitted weight that can be lifted by one person, without aids. At the time of submission, one person may lift a maximum of 25 kilograms without aids. By not allowing the weight of the removable active unit to exceed this limit, it is possible that the replacement of a removable active unit, which has a defect and / or malfunction, can be done by one person. As a result, either personnel costs can be saved or more than one removable active unit can be replaced at different locations. Furthermore, the person does not need specific knowledge to realize the exchange of the active unit.

Preferably, the passive unit comprises a panel 5 provided with an inner space, which serves as a discharge channel for flue and / or waste gases and / or as a supply channel for air. By implementing the passive unit in this way, space can be saved. After all, it is no longer necessary to arrange pipes and / or channels for the discharge of flue and / or waste gases and / or the supply of air separately in the heating assembly. A result can be that the whole can be made more compact, and can therefore be installed in, for example, smaller spaces. These parts of a heating assembly 15 are also among the most robust parts of the whole, and therefore there is virtually no risk of defects.

It is advantageous here that the interior space of the passive unit is of modular construction. There is a possibility that dust accumulates in the air supply and / or exhaust for flue and / or waste gases, and when this happens, such a supply and / or exhaust must be cleaned. By modularly building the interior space, it is relatively easy to open and clean it. Moreover, it is conceivable that cleaning is simpler and more thorough.

It is advantageous here that the lines of the passive unit are suitable for supply central heating, return central heating, cold water, hot water, gas or sewer discharge. In order for a heating unit to function fully, all the aforementioned pipes are required, and the greatest efficiency of the invention is achieved when all the necessary pipes are actually connected to the heating unit at the same time. Possible 6 connection elements for effecting this connection are shown in Figure 5/6.

Then it is furthermore also possible that the passive unit comprises more than one connection provision, which are suitable for a pressure vessel, a bypass, overflow safety or room thermostat and electricity / outdoor sensor. By including such connection arrangements in the passive unit, the connections can be made immediately when the removable active unit is positioned. The whole then works according to the "plug and play" principle, the removable active unit is positioned and the heating assembly can be put into operation immediately.

In a further embodiment, the coupling elements 15 are provided on the lines of the passive unit, the line connections of the active part, or between the lines of the passive unit and the line connections of the active part. By arranging the coupling elements in this way, it is simple to replace or adjust them if, for example, a coupling element is defective or if an improved embodiment is available.

Below follows a description of a few embodiments shown in the accompanying drawings, which are provided by way of example only, and in which identical or similar parts are designated components and elements with the same reference numbers, and in which:

Figure 3 shows the passive unit of a heating assembly according to the invention;

Figure 4 shows another embodiment of a heating assembly according to the invention, Figure 5 shows a cross-sectional view of a two-part coupling element that is suitable for use in an embodiment of a heating assembly according to the present invention, and

Figure 6 shows another embodiment of a two-part coupling element.

Figure 1 shows a heating assembly 1 according to the invention. The heating assembly 1 comprises a passive unit 2 and a removable active unit 3. The figure clearly shows that the passive unit 2 is provided with more than one line 5. The removable active unit 3 is provided with an integrated electronic module 4. In this embodiment, it is not possible to open the detachable active unit without special tools. When a defect and / or malfunction occurs, the entire active unit 3 will be replaced by another active unit, and will be repaired at a different time and location. The heating assembly 1 is briefly out of use in this way.

In the embodiment of Figure 1, an arm 16 is pivotally mounted on the passive unit 2. The arm 16 engages a pin 17 on the outside of the active unit 3, for example on the outside of a housing 18 around sensitive components and / or or parts in the active part 3. The arm 16 thus forms a lever or a press for forcefully bringing the passive part 2 and the active part 3 together when the arm is pivoted in the direction of arrow A, under engagement of the pin 17. In an embodiment not shown, the arm can be fixed and can then form a latch to also keep the active part 3 and the passive part 2 together. Although the arm is shown in view outside the housing 18, it is preferably arranged out of sight in the housing 18. It is also possible to arrange the arms in a different orientation.

Figure 2 shows the inside of a heating assembly 1, with the individual components visible. The main components that are visible here are the pump 7, the heat exchanger 6, an optional hot water tank or reservoir 15 and the burner 8. These components are arranged in a modular way and can also be replaced as such. In this figure, the electronic module 4 is integrated in the passive unit 2. The passive unit and the removable active unit are coupled at point 11. The air enters the heating assembly 1 at 9 and the flue and / or waste gases leave the heating assembly at 10.

Figure 3 shows a passive unit 2 of a heating assembly 1, wherein the passive unit 2 is in the form of a panel with interior space, which is accessible via opening 13 and is located on the top of the passive unit. In this embodiment of the invention, the inner space is used as a discharge channel for flue and / or waste gases that leave the heating assembly. The removable active unit is positioned on the passive unit by means of the U-shaped positioning means 12, provided with a profile 14, which serves as guide means. The active unit (not shown) has a profile at the rear that can be slid into the profiles of 14 from above. For this purpose, the active unit is placed against 2 with the profile just above the profiles 14. Subsequently, the active unit 3 is lowered into the profiles 14 to the end position, so that the pipe connections are simultaneously coupled to the corresponding pipes 5 and the assembly is ready for use. In this embodiment the active unit is applied with one vertical movement. It is therefore possible that the guide means and positioning means are embodied as one component. Think here of two profiles, which connect to each other and ultimately carries the removable passive part.

Figure 4 shows another embodiment of the invention. The heating assembly comprises a removable active unit 3, an electronic module 4 and a passive unit 2. The lines 5 of the passive unit are oriented in a different direction, so that the removable active unit can be arranged with a horizontal movement. The hollow space in the passive part 2 formed as panel 20 is also of a different shape, wherein 13 provides access to the inner space. The smoke and / or waste gases which end up in the inner space can leave the assembly via the outlet 10. The active unit is positioned on the positioning means 12.

Figure 5 shows in cross-section a two-part coupling element 20, which is suitable for use in an embodiment of a heating assembly according to the present invention. A pipe connection 19 of the active part 3 of the device 1 can hereby be connected to a pipe 5 of the passive part 2. The coupling element 20 comprises two parts, one part of which 21 with the pipe connection 19 and the other part 22 with the pipe 5 is connected. The part 21 comprises a chamber 23 in open communication with the pipe connection 19 with a passage 24 through which a pressure needle 25 extends. A head 26 of the pressure needle 25 can close the passage 24 to form a valve, under the action of a pressure P2 in the pipe connection 19. The part 22 comprises a chamber 27 in communication with pipe 5 with a non-return valve 28 therein. The non-return valve 28 in the chamber 27 forming a valve is oriented to a passage 29, and under the action of a pressure P1 in the conduit 5, the non-return valve is inclined to assume a closed position in the chamber shown in the figure for the passage 29 to close. The part 22 comprises on the outside thereof a locking means, such as screw thread 30, and the part 22 has a ring 31 with internal screw thread 32. In a coupled state of the parts 21, 22 it can be ensured with the threads that the parts 21 , 22 are held together. As a supplement or as an alternative, the pressing means shown in Figure 1 will suffice. When the parts 21 and 22 are not connected, liquid will be trapped in the pipe 5 of the active part 3 and if liquid is present in the pipe connection 19, it will remain in the pipe connection 19.

When the parts 21, 22 are subsequently brought together, the pressure needle 25 protrudes against the non-return valve 28, so that both passages 24, 29 of the two parts 21, 22 are arranged openly. If the parts are detached from each other, only a very minute amount of liquid will be released. In the embodiment thus designed, the coupling parts and the valves are integrated units.

Figure 6 shows a cross-section of another embodiment of a two-part coupling element 20. In this embodiment, one part 21 is also arranged on the active part and the other part 22 on the passive part 2. The part 21 on the active part 3 comprises a non-return valve 28 which closes the passage 24 in the uncoupled state by pressure P2 or by spring pressure. The part 21 further comprises a locking means 30 on the outside. The other part 2, 5, which is located on the passive part 22, is located at the end of pipe 5. Pipe 5 flows into chamber 27, which is closed in shut-off condition by valve 33. Furthermore, part 22 comprises a passage 29 , which is arranged to receive the first part 21. The passage 29 further comprises a pressure needle. When the two parts 21, 22 are coupled, the pressure needle 25 will push the non-return valve 28 to open the passage 24. The valve 33 will also open and then it is possible for a fluid, which is located in the pipe 5 and chamber 27, to flow to the active part.

After taking cognizance of the foregoing, many alternative and additional embodiments will occur to those skilled in the art, all of which are within the scope of the present invention, as defined in the appended claims. Only then, when an embodiment deviates in letter or spirit from the specific definitions of the scope of protection, in particular the independent claims, is there no longer an embodiment according to the invention.
