Abstract

The radiator (1) has pairs of vertical sections each comprising top and bottom chambers (4-4x,3-3x) connected by a vertical passage (5-5x). The chambers are connected so as to form top and bottom (7, 6) horizontal passages for the heating liquid. The inlet and discharge valves (8, 9) are fitted in opposite bottom chambers (3, 3x) open to the outside, and the regulator (10) and air vent (11) valves are similarly mounted in opposite top chambers (4, 4x). The two opposite bottom chambers are mirror-images of each other, as are the two top ones. The union (14) of the inlet valve is so designed that it shuts off the flow between its chamber (3) and the adjacent one (3'), so that all the heating liquid flows into the top passage (40 via the connecting passage (5), in which the regulator valve is mounted.

Description

The present invention relates to a radiator with built-in fittings, according to the preamble of claim 1.

The radiators or radiators of the type mentioned above are used in residential heating systems. In order to be able to perform their function optimally, they must be equipped with four valves. These are: the inflow and backflow valve, with which the access of the heating fluid into the body itself is opened and closed; the regulating valve, which is used immediately downhill from the inflow valve to regulate the flow of warm liquid through the radiator, which is adapted to the specific needs of the room to be heated and the outside temperature: this valve can be manufactured as a manually regulatable valve or with thermostatic or thermoelectric Regulation should be overlooked; the relief valve for the ventilation of the radiator, which must be installed in the top part of the radiator for its function; the drain valve for the heating liquid, for its functions, is located in the lowest part of the radiator.

The conventional types of radiators were supplied to the installer with connections on the building, generally threads to secure the valves, that is, without the actual valves. It was therefore the job of the installer to mount the valves in the correct place and to carry out the necessary checks for the tightness of the radiator and the flow regulation after connecting the radiator to the heating liquid flow and radiator filling. This assembly operation on the construction site was very time consuming and also had the disadvantage that the work was carried out in rooms with emergency equipment, so that the radiators were often not completely sealed and had to be checked again later. Attempts have therefore been made to overcome these disadvantages by producing radiators with partially built-in connections. In fact, steel plate radiators are known from practice - that is to say those where the radiator consists of two shaped, welded sheets which form an intermediate space for the passage of the warm water and which have outer fins which act as heat radiation fins. in which a lower inlet connection, which is suitable for a function of the radiator in both single-pipe and two-pipe operation (concepts which are explained in more detail below, although they are accessible to any professional), directly through a vertical pipe with the regulating valve, the is attached to the top of the same side of the radiator.

However, one cannot speak of radiators with built-in valves here, but only of radiators with built-in connecting pieces.

In fact, these radiators require the installation of an additional inlet valve, for example if you want to remove the radiator without draining the lines, a process that is necessary for the replacement or maintenance of the radiator, for painting the wall behind the radiator or even to give the installer the opportunity to run and test the system before connecting the radiator. Furthermore, the above-mentioned radiators with built-in connecting lines between the inlet connection and the regulating valve are asymmetrical, since they have this connection only on one side and therefore do not allow the radiator to be installed in reverse. One must therefore have radiators with right connections and radiators with left connections, which complicates both the manufacture and the logistics of such radiators.

• a) der Heizkörper soll dem Installateur auf dem Bau als wesentlich mit allen Funktionselementen komplett ausgerüstete Einheit abgeliefert werden, das heisst mit allen in der Fabrik montierten und geprüften Ventilen. Dies vermeidet, dass der Installateur die Montage und besonders die Dichtigkeitskontrolle auf dem Bau ausführen muss.
• b) der Heizkörper soll dem Installateur verpackt geliefert werden, sodass er während allen Montagephasen geschützt ist, womit irgendwelche Schäden an seinen Oberflächen sowie an den an ihn befestigten Ventilen vermieden werden.
• c) der Heizkörper soll so gefertigt sein, dass seine Montage gleichgültig auf der einen oder entgegengesetzter Seite erfolgen kann, das heisst, er soll im Vergleich zu einer senkrecht zum Körper selbst vertikalen Fläche spiegelbildlich sein.
• d) der Heizkörper soll von einfacher und nicht kostspieliger Herstellung sein.

The purpose of the present invention is therefore to propose a new type of radiator with the following main properties:

• a) The radiator should be delivered to the installer on site as a unit that is fully equipped with all functional elements, i.e. with all valves installed and tested in the factory. This prevents the installer from having to carry out the installation and especially the tightness check on the building.
• b) the radiator should be delivered to the installer in a packaged manner so that it is protected during all assembly phases, thus avoiding any damage to its surfaces and to the valves attached to it.
• c) the radiator should be manufactured in such a way that it can be assembled indifferently on one or the opposite side, that is, it should be a mirror image of a vertical surface perpendicular to the body itself.
• d) the radiator should be simple and not expensive to manufacture.

These purposes are achieved by a radiator which corresponds to the characteristics of claim 1. A radiator of the same type can be assembled and tested in the factory with considerable time savings and greater precision and can be dispatched ready for insertion in the heating system circuit. This will result in a significant reduction in time in the assembly on the building and a remarkable improvement in work care. In comparison to the above-mentioned radiators known in the prior art, it can be noted that the one according to the invention does not have a separate connecting tube between the lower inflow connection and the regulating valve, but that this vertical connection channel consists of the elements forming the radiator itself and can be indifferent the right or left side of the radiator. In fact, this choice only depends on the position in which the individual valves are installed in the body and does not require any adjustment from the body itself: this is machined in the factory with a few work steps (four threads in practice) and is mirror-inverted opposite a vertical plane intersecting it vertically.

Another series of additional advantages can be achieved using the characteristics that are the subject of some preferred embodiments of the invention.

Thus, according to a first preferred variant, the elements forming the radiator are made of die-cast aluminum and are welded to one another in accordance with the lower and upper chambers.

This type of manufacture of the elements, known per se and applied, is particularly suitable in the scope of the present invention, since it is thus easy to achieve the horizontal lower and upper flow channels connected by a series of vertical channels, the first of which - in the sense of the water inlet - serves as a vertical connecting channel between the inflow valve and the regulating valve. The production of the individual elements by die-casting aluminum is therefore a simple and inexpensive method of manufacturing the inventive Radiator. However, it is clear that this is not the only way of realizing a radiator of the same type, which, although less efficient, could also be carried out with welded tubes or curved and welded steel sheets. According to the preferred embodiment variant according to claim 3, the elements forming the body have a vertical, flat and continuous radiation wall at least on the side which is to be located on the outside. The advantage of this embodiment is above all of an aesthetic nature, since today the continuous and smooth shape of the visible wall of the radiator is sought.

The preferred variant according to claim 4, which provides that at least the inflow, outflow and blow-off valves, attached to three of the four corners of the radiator, are contained inside the rectangular border of the radiation wall of the actual body, is mainly of an aesthetic nature, even if thanks to this measure, better protection of the elements for transport and also after assembly is achieved, since these remain hidden behind the wall of the radiator.

Regarding the regulating valve, which is not necessarily intended to be hidden behind the bezel of the front plate or front wall of the radiator, it should be noted that the element in question also appears hidden in relation to the connection, but is in many cases it is useful if it emerges from the side of the border, either for manual control - and then it is useful if it can be easily recognized by the worker - or that it is a thermostat that keeps the ambient temperature in the most neutral way Way to display as possible.

The claim 5 provides that the inflow valve to its lower chamber by a threaded screw, the axis of which coincides substantially with the axis of the lower channel of the radiator. Thanks to this provision, it is therefore possible to tilt the radiator around the horizontal axis of its lower duct without having to disconnect the two connecting pipes (the one from the inflow and the other from the backflow), since the body of the inflow valve can remain firmly in the room. In addition to the previously mentioned advantage of being able to tip the radiator for maintenance and cleaning work, this also means that if a suitable inflow valve is used, the radiator can be disconnected from the hot water pipe without having to empty the circuit itself . For this purpose, however, the inflow valve must have some special properties that are the subject of claim 6 of the present invention. Without going into the details, it should be mentioned here that an inflow valve that meets the conditions for tilting the radiator about the horizontal axis its lower channel and thus mountable in the radiator of the present invention, satisfactorily fulfilled, is described in the parallel patent application of the same applicant No. 00301 / 94.5, deposited on the same day with the Federal Office for Intellectual Property in Bern. We therefore also refer to the aforementioned patent application, which describes a rotary slide valve which, in addition to separating and installing the radiator without draining the water circuit, allows a so-called single-pipe operation (in which only part of the circulating water flows into the individual radiator, while the rest against the subsequent radiator) or two-pipe operation (in which all the circulating water flows into the radiator) of the radiator.

These are concepts that are clear for every professional and are in any case described in more detail in the patent application mentioned, to which reference is made here. As far as the present patent application is concerned, it is sufficient to remember that the regulating valve is attached to the radiator in such a way that it is tilted about the horizontal axis of its lower channel and that the radiator can possibly be operated with a single-pipe or two-pipe function.

The claim 7 relates to an embodiment of the radiator with coaxial, upper connection threads and lower, also coaxial and mirror-image connection threads, the advantage of which on the one hand is the simplified manufacture of the radiator, since it is only drilled in the four corners and cut with two identical threads and on the other hand that the radiators are freely mounted in the right or left position.

In fact, this position is not determined in the course of the manufacture of the radiator - which always involves difficulties and costs - but only at the moment of valve assembly, that is, if you already know the exact use of the radiator.

The manufacturing process of the radiator according to the invention, which provides for the assembly of the valves installed in the radiator in the workshop, has practical advantages such as work rationalization and thus. Cost reduction and increased security, and which have already been mentioned several times as purposes of the invention and about which it is therefore no longer necessary to report in more detail.

The invention will now be illustrated with the aid of a preferred exemplary embodiment, its corresponding drawings and a number of those illustrated Variants, better described.

The heater 1, the basic nature of which is known in the prior art and does not form the subject of the present invention, consists of a plurality of paired, vertical elements, 2,2 ', 2'', ..., 2 ^x , each of which one lower chamber 3.3 ', 3'', ..., 3 ^x , an upper chamber 4.4', 4 '', ..., 4 ^x and a vertical connecting channel, 5.5 ', 5'', ..., 5 ^x , which connects the two chambers 2.2 ', 2'', ..., 2 ^x corresponding to the same element. The lower chambers 3,3 ', 3'', ..., 3 ^x are then mutually connected and form a lower horizontal channel 6, while the upper chambers 4,4', 4 '', ..., 4 ^x mutually are connected to form an upper, horizontal channel 7. The mutual connections of the lower chambers 3,3 ', 3'', ..., 3 ^x and or 4,4', 4 '', ..., 4 ^x can be in any suitable, not shown, such as by threaded bushings, by press mounting, etc. However, if the inventive radiator consists of die-cast aluminum elements, as provided in an advantageous form of the invention, the mutual connection should preferably be done by welding the contact surfaces of the individual chambers. In any case, this corresponds to the known prior art and need not be described further here.

• a) in einer der beiden unteren Kammern 3,3 ^x , in der Fig. 1 die mit 3 bezeichnete rechts, ist das Zuflussventil 8, in der Fig. 1 nur symbolisch mit gestrichelten Linien angegeben, eingebaut;
• b) in der anderen 3 ^x der beiden unteren gegen Aussen offenen Kammern (3,3 ^x), das heisst, der unteren Kammern der äusseren Elementen des Heizkörpers, jene links in Fig. 1, ist das Abflussventil 9 eingebaut, ebenfalls mit gestrichelten Linien angegeben.
• c) in der oberen, an der Aussenseite des Heizkörpers 1 geöffneten Kammer 4, in welchem sich das Zuflussventil 8 befindet, das heisst, an der rechten Seite, ist das Regulierventil 10 eingebaut, währenddem,
• d) in der obeneren Kammer 4^x der Heizkörperseite, wo sich das Abflussventil 9 befindet, ist das Luftabblaseventil 11 eingebaut, das zur Entlüftung des Heizkörpers im Moment seines Auffüllens mit Heizflüssigkeit, bzw. Wasser, dient.

The specific characteristics of the inventive radiator, however, are as follows:

• a) in one of the two lower chambers 3.3 ^x , in FIG. 1 the one labeled 3 on the right, the inflow valve 8, in FIG. 1 only symbolically indicated by dashed lines, is installed;
• b) in the other 3 ^{x of} the two lower chambers open to the outside (3.3 ^x ), that is, the lower chambers of the outer elements of the radiator, that on the left in Fig. 1, the drain valve 9 is installed, also with dashed lines specified.
• c) in the upper chamber 4, which is open on the outside of the radiator 1 and in which the inflow valve 8 is located, that is to say on the right-hand side, the regulating valve 10 is installed, while
• d) in the upper chamber 4 ^x the radiator side, where the drain valve 9 is located, the air relief valve 11 is installed, which serves to vent the radiator when it is filled with heating fluid or water.

Valves 8, 9, 10 and 11 are now inventively assembled and tested in the workshop, where it is then possible that practical Reasons for the head 12 of the control valve 10, which is normally removed from the casing 13 of the radiator 1 for reasons already mentioned for packaging and transport and put on the axle and is then fixed in the heating system only after the final assembly of the radiator.
The structural details of the individual valves, which, however, are not essential for the present invention, are described below with the aid of the following figures.

• e) die beiden unteren, gegen Aussen offene Kammern 3 und 3^x , das heisst an die beiden äusseren Elemente 2 und 2 ^x des Heizkörpers angebracht, sind spiegelbildlich , also eine im Vergleich zur anderen symmetrisch gefertigt, sowie dies auch die beiden oberen, gegen Aussen offenen Kammern 4 und 4 ^x sind Das bedeutet, dass die beiden unteren Kammern 3 und 3^x ,bzw. die beiden oberen Kammern 4 und 4^x die gleichen Elemente aufnehmen können, das heisst, sie sind austauschbar- in der Funktion. Dank dieser Tatsache kann das Zuflussventil 8 in der Kammer 3 sowie in jener 3^x montiert werden und entsprechenderweise das Regulierventil 10 in der Kammer 4 oder jener 4^x . Durch diese Tatsache kann somit ein Heizkörper mit rechter oder linker Flüssigkeitszuflussmontage verwirklicht werden, trotzdem immer die gleichen Elemente in Anwendung kommen, was sowohl die Herstellung sowie auch die logistike Organisation solcher Körper erheblich vereinfacht. Schlussendlich muss noch die Bedingung eingehalten werden
• f) die vorsieht, dass der Anschluss 14 des Zuflussventils 8 in einer solchen Weise gefertigt ist, dass der Durchgang seiner unteren Kammer 3 gegenüber der anliegenden Kammer 3' geschlossen wird, sodass die ganze Heizflüssigkeit in die obere Kammer 4, geführt wird, wo das Regulierventil 10 durch den die beiden Kammern 3 und 4 verbindenden, vertikalen Kanal 5 eingebaut ist. Natürlich ist das für die Kammern 3 und 4 oben erwähnte durch die symmetrische Spiegelbildlichkeit der Kammern 3 und 3^x ,bzw. 4 und 4^x , auch für die Kammern 3^x und 4^x gültig, falls das Zuflussventil links vom Heizkörper 1 und nicht rechts, wie in Fig. 1 gezeigt, montiert wird.
  Dank dieser Beschaffenheit des Heizkörpers 1, bildet der vertikale Verbindungskanal 5 zwischen den ersten unteren und oberen Kammern, im Sinne vom Flüssigkeitsdurchfluss im Heizkörper 1, automatisch die beschriebene Verbindung zwischen dem Zuflussventil 8 und dem Regulierventil 10, welche im Stand der Technik als solches bekannt ist und für die Regulierung des Heizkörpers 1 notwendig ist. Dies alles ohne eine zusätzliche Leitung vorsehen zu müssen, wie dies hingegen vom Stand der Technik verlangt wird.
  In der Fig. 1 sieht man auch, wie die Elemente, 2,2',...,2^x, aus denen der Heizkörper besteht, wenigstens auf der sich nach Aussen befindenden Seite eine vertikale Strahlungwand 15,15',...,15^x besitzen, was in Fig. schematisch durch gestrichelte Linien dargestellt ist. Es handelt sich um eine bevorzugte Form des Heizkörpers, welche einerseits erlaubt, eine flache durchlaufende Strahlungswand von angenehmen Aussehen und von hoher Leistung an Wärmestrahlung zu bilden. Andererseits erlaubt die Anwesenheit einer aus einer Gruppe von vertikalen Wänden 15,15',15'',...,15^x bestehenden Strahlungswand eine andere bevorzugte Variante des erfinderischen Gegenstandes zu verwirklichen, da es in diesem Falle möglich ist, vorzusehen, dass die an drei der vier Ecken des Heizkörpers (1) angebrachten Zufluss- 8, Abfluss-9 und Abblaseventile 11, im Innern der Einfassung 13 der aus einzelnen, vertikalen Wänden 15, 15',15'',..., 15^x bestehenden Strahlungswand eingeschlossen seien Dank dieser Vorkehrung bleiben die vorerwähnten Ventile geschützt und unsichtsbar, was ästhetisch vorteilhaft ist und auch die Verpackung und den Transport des Heizkörpers somit vereinfacht.
  Eventuell vorstehend bleibt hingegen, wie bereits gesagt und begründet, der Kopf 12 des Regulierventils 10.

In contrast, the inventive heater 1 has two further basic properties. These are:

• e) the two lower, open to the outside chambers 3 and 3 ^x , that is attached to the two outer elements 2 and 2 ^{x of} the radiator, are mirror images, so one is symmetrical compared to the other, and this also the two upper, against External chambers 4 and 4 ^x are. That means that the two lower chambers 3 and 3 ^x , respectively. the two upper chambers 4 and 4 ^x can accommodate the same elements, that is, they are interchangeable - in function. Thanks to this fact, the inflow valve 8 can be mounted in the chamber 3 as well as in that 3 ^x and accordingly the regulating valve 10 in the chamber 4 or that 4 ^x . Due to this fact, a radiator with right or left liquid inflow assembly can be realized, nevertheless the same elements are always used, which considerably simplifies both the manufacture and the logistical organization of such bodies. In the end, the condition has to be met
• f) which provides that the connection 14 of the inflow valve 8 in a is manufactured in such a way that the passage of its lower chamber 3 with respect to the adjacent chamber 3 'is closed, so that all the heating liquid is led into the upper chamber 4, where the regulating valve 10 through the vertical channel connecting the two chambers 3 and 4 5 is installed. Of course, this is for the chambers 3 and 4 mentioned above by the symmetrical mirror image of the chambers 3 and 3 ^x , or. 4 and 4 ^x , also valid for the chambers 3 ^x and 4 ^x , if the inflow valve is installed on the left of the radiator 1 and not on the right, as shown in Fig. 1.
  Thanks to this nature of the radiator 1, the vertical connecting channel 5 between the first lower and upper chambers, in the sense of the liquid flow in the radiator 1, automatically forms the described connection between the inflow valve 8 and the regulating valve 10, which is known as such in the prior art and is necessary for the regulation of the radiator 1. All of this without having to provide an additional line, as is required by the prior art.
  In Fig. 1 you can also see how the elements, 2,2 ', ..., 2 ^x , of which the radiator is made, at least on the outside, a vertical radiation wall 15, 15', ... , 15 ^x , which is shown schematically in Fig. By dashed lines. It is a preferred form of the radiator, which on the one hand allows to form a flat continuous radiation wall with a pleasant appearance and high heat radiation output. On the other hand, the presence of a radiation wall consisting of a group of vertical walls 15, 15 ', 15'', ..., 15 ^x allows another to implement a preferred variant of the inventive subject matter, since in this case it is possible to provide that the inflow 8, outflow 9 and blow-off valves 11 attached to three of the four corners of the radiator (1), inside the casing 13 or individually , vertical walls 15, 15 ', 15'', ..., 15 ^x existing radiation wall should be included Thanks to this provision, the aforementioned valves remain protected and invisible, which is aesthetically advantageous and also simplifies the packaging and transportation of the radiator.
  However, as already mentioned and justified, the head 12 of the regulating valve 10 may remain above.

According to a further advantageous embodiment of the invention, shown in FIG. 2, the inflow valve 8 is formed by a threaded screw 16, the axis xx of which essentially coincides with the axis yy (FIG. 1) of the horizontal, lower channel 6, around which the radiator 1 can thus be tilted without separating the connecting pipes 17 and 18 from the inflow valve 8 of the heating liquid, attached to its open, lower chamber (in the specific case that 3 on the right).

The construction of the valve 8, shown as an example in its main elements and in simplified form in Fig. 2, shows an inner tube 19 which is screwed into the thread 16 of the element 2. On the tube 19 there is a bushing 20 which is connected to the body of the element 2 in a sealing manner by a sealing ring 21. The socket 20 has a connection for the inflow line 18 of the heating liquid, which subsequently penetrates the path designated by arrow f 1 into the connecting channel 5 (comparison with FIG. 1). The liquid thus arrives at the regulating valves 10 (FIG. 1), where the flow depends on Heating needs is regulated, flows through the entire radiator 1 and flows through this by means of the lower, horizontal through-channel 6 and the return pipe 17. Thanks to the fact that the inflow valve, which is only shown schematically in Fig. 2, but is actually of a complicated nature, since it is provided, for example, with elements for closing the passages 17 and 18, is made in such a way that the radiator can be tilted or rotated about the axis xx of the valve 8, which corresponds to the axis yy of the radiator 1, the above-mentioned advantages are achieved.

Such a valve type, which is primarily used for a radiator according to this invention in order to achieve further advantages from it, is described in the applicant's parallel patent application, filed on the same day with application number CH 00 301 / 94-5.

Accordingly, reference is expressly made here to this patent application. It is sufficient here to note that, thanks to the properties of the inflow valve mentioned, the radiator 1 can be tipped over with respect to the axis y-y of its horizontal, lower chamber without the connecting pipes 17 and 18 having to be disconnected.

According to a further preferred embodiment of the invention, always shown in FIG. 1, the connections 14, 23 for the inflow 8 and the outflow valve 9, or those 24, 25 for the regulating 10 and relief valve 11, consist of threads which are coaxial with the horizontal passage channel of the lower liquid 6, or with the horizontal passage channel of the upper liquid 7. Furthermore, these coaxial connections 14, 23 and 24, 25 are mirror images of one another. This characteristic is essential for a free assembly of the inflow 8 and outflow valves 9, or regulating 10 and relief valves 11, to the right or left of Radiators 1. In addition, the mirror image of the radiators facilitates their manufacture, since they can be drilled and tapped efficiently using simple tools.

Another preferred embodiment of the invention provides that the inflow valve 8 is a rotary slide valve which is coaxial with the axis of its connection x-x and allows one-pipe and two-pipe operation of the radiator. A valve like the one mentioned here is described in detail in the applicant's parallel patent application. We therefore refer to this description, which is considered an integral part of the present invention, and we therefore refrain from discussing this valve here.

FIGS. 3, 4 and 5 show the corresponding structural details which are known to every professional and which are not essential for the purpose of the present invention, the regulating valve 10 with regulating head 12, the relief valve 11 and the drain valve 9. It is important to note that the regulating valve 10 and the one for the blow-off 11 are manufactured in such a way that they can be installed on the radiator on the right or left, since the connecting threads of the chambers 4 or 4 ^{x of} the elements 2 or 2 ^x are exactly the same, as is the nature of the whole chamber. On the other hand, as far as the type of valve used is concerned, this is of no importance in the scope of the present invention. 4 shows only as an example that a valve with an automatic opening and equipped with a float 26 has been used as a relief valve.

The same is repeated for the inflow valve 8 shown in FIG. 2 and the outflow valve 9 shown in FIG. 5: here too the only important one The fact that the two valves are manufactured in an interchangeable manner, that is, can be installed in chamber 3 or 3 ^x of elements 2 or 2 ^x , regardless of whether on the right or left. This interchangeability of the valves 8 and 10, or 9 and 11, which is derived from the mirror image of the lower and upper connecting parts of the radiator, is the only basic condition for the actual valves and what must be considered in order to achieve all of the advantages contained in the present invention .

Finally, claim 8 relates to a manufacturing and assembly method of the inventive radiator 1. It provides that the inflow 8, outflow 9 and the relief valves 11, as well as the connection piece 27 (FIG. 3) of the regulating valve 10 in the workshop the radiator 1 are assembled and calibrated.

In fact, this allows the radiator 1, complete with fittings, to be sent to the installer on the building, who has no other task than to unpack it and assemble it on the wall, and to connect the threaded connection piece to the inflow valve 8. It is clear here that this means a substantial reduction in the assembly work on the building and also allows defects and error sources, such as those associated with the hydraulic density or calibration errors, to be eliminated.
