Description

TECHNICAL FIELD

[0001] The present invention relates to the field of heating devices. More specifically, the present invention is suitable for providing an electric heating device that uses the action of a constant power heating cable inserted into its structure and regulates its operation with a suitable power regulator. BACKGROUND

[0002] In the past, the installation of thermal conditioning systems such as radiators had only one reason: to ensure hot climates in order to better prepare for the coolest seasons. To prove this, a rather limited range of products appeared on the market; in fact, few variants appeared, which had different length and width standards, but also had almost identical forms and designs. They mainly met the use requirements, rather than enhancing the aesthetic appearance of the individual home, basically offering only one color choice, among others. In recent years, this equipment has been reevaluated and the radiator is now no longer just a heating element, but plays the role of an actual decorative element in the field of interior design. Its style can be unique and unusual, with original shapes, or it can have linear and basic forms.

[0003] Most radiator models are modular, with different sizes that can adapt to different spaces and factory requirements. In commercial use, both transverse and longitudinal arrangements can be found. The implementation of electric radiators on the market usually consists of powering a traditional hydraulic heater by inserting a liquid (water or glycol) inside it, which is suitable for forming a kind of "sealed container" with it, which can be heated by an enhanced cartridge heating element. The heating element, which has a rod-like shape, is inserted into the manifold of the towel dryer, its power being approximately close to the scattering capacity of the towel dryer relative to its size, and is always excessive in order to accelerate the heating of the liquid. The heating element heats the liquid it comes into contact with, while one thermostat or more inserted into the upper part of the cartridge rod regulates the heat intensity they generate (in high-quality manufacturer models, 30°-60°-80° are managed by small step controls placed at the bottom). However, there is a problem, since the liquid heated in the sealed container expands in proportion to the temperature, a pressure is generated in the heater as a function of the temperature in the room, which increases if towels are placed on it. In this context, the intervention of the thermostat is very important when using the radiator at maximum power, in fact, this provides a continuous closing and opening cycle for the cartridge, resulting in considerable delays in achieving the desired temperature and lower energy efficiency.

[0004] One example of a patent that attempts to solve several of the problems described above is the object of patent application IT MI20061579A1 by G. DE LONGHI. This invention describes a radiator for heating an environment, which comprises an electric heating device adapted to generate a natural circulation of a heat carrier fluid. The radiator has two manifolds and various diffusers connected thereto, in which the heat carrier fluid is located, which, when heated by the tubular heating elements inserted in the manifolds, transfers the heat to the entire device.

[0005] Another possibility for a dry electric radiator is to pass the heating elements inside the tubes, a solution that has the great advantage of ensuring a more direct and uniform heating of the entire radiator.

[0006] There are several patents that provide various types of solutions in this technical field.

[0007] One example is the object of patent application GB2212037A by K. PEARCE. This invention relates to an electric towel drying rack. The device comprises transverse and vertical tubular elements connected by hollow spherical connectors. Inside the tubular elements, a flexible heating cable is passed, which is contained inside a sheath of electrically insulating material. The cable comprises active heating zones arranged inside the tubular elements, in which a portion of the heating element is connected to a current line, so that there is a current path that passes through the element from one current conductor to the other. The portion of the cable arranged inside the vertical tube has passive zones, in which there is no current path through the corresponding portion of the heating element. The heating cable is powered by a hidden power cable, which extends through the end of the tubular portion, which is adapted to be mounted against the surface of a wall or floor.

[0008] Another example is the object of patent application EP3339764A1 by R. SPERANZON and S. VALENTE. This invention relates to a modular device for heating an environment, a method for the implementation of the device and a related installation kit. The device has a modular structure, which comprises at least one column and a plurality of modules, which can be assembled together and can be inserted slidingly on the column. Inside the column and the modules, a flexible heating cable is then passed.

[0009] The inventions reported so far, as non-limiting examples only, represent the state of the art available.

[0010] The reported inventions, while providing various types of solutions to the above-mentioned problems, also have a series of limitations and intrinsic problems. In fact, none of the above-mentioned inventions allow flexibility during assembly to ensure that the installer can install the device, orient it in any direction (rotating it on a plane parallel to the support on which the device is installed), nor to install the control unit in any position after said orientation. In fact, the above-mentioned inventions have suitable power cables located in specific areas, or even control units installed directly on the uprights of the device. The latter of the above-mentioned features has shown to be particularly problematic in heating devices in which heat spreads in a uniform manner, since the control unit and all the electrical / electronic components inside it are also subjected to the continuous variation of the heat of the device. Moreover, in the presence of suitable thermal insulation material, the outer surface in contact with the buttons and / or screen will still have the temperature of the heat sink, and in any case the insertion of thermal insulation material makes the installation more complex, slow, expensive and limited to specific positions. Furthermore, the above-mentioned inventions have the problem of controlling the temperature and therefore the power delivered by the flexible cable and / or by the cylindrical heating element by closing and opening the cycle, which not only reduces the energy efficiency of the device, but also involves a significant occupation of the availability of energy at home, for example, negatively affecting the possibility of simultaneously turning on multiple electrical appliances and the heating device. Despite the presence of the flexible heating cable, all the above-mentioned inventions have cold zones caused by the "coil" shape through which the cable passes inside the device.

[0011] Another important aspect is that most of the electric heating devices currently on the market are made with rigid structures consisting of tubes welded to manifolds. This "rigid" structure with the inlet of the heating element into the radiator generates annoying noises (clicks) during operation, caused by the thermal deformation of the metal (proportional elongation and shortening of the operating temperature equal to about 0.01 mm per degree Celsius per meter). The intensity of the noise, strong or weak, will depend on many factors such as the correct calibration of the heating element proportional to the size of the heater. In addition to the noise problem related to the thermal variation of the device, there are other problems and other limitations of the towel dryers and electric radiators currently on the market, listed as follows:

[0012] - they usually have a "closed structure", i.e. a structure that does not allow the expulsion of the hot air inside, generates high and dangerous internal pressures that, over time, cause the deterioration of the components of the device;

[0013] - having a "closed structure" also causes an inefficiency in the distribution of heat within the environment, since there is no introduction of hot air, but only heat propagation by the air outside the heating device;

[0014] - the structural type of these devices generally limits them to have an aesthetic appearance that is less "flexible", i.e. the tubes must be straight (as in the case of the patent application EP 3339764 A1 by R. SPERANZON and S. VALENTE, in which the uprights cannot be curved or wavy, because otherwise they would prevent the modules connected to the central tuning device from sliding into the appropriate rails inside them);

[0015] - moreover, these devices generally show signs of engagement between the various elements due to the structural need, thus having a limited aesthetic value, as in the case of the patent application GB 2451109 A by D. LENNON and M. BETZ. It is also important to emphasize that the cases of the above examples and all similar cases are characterized by the heat exchange that mainly occurs through convection inside the vertical uprights, therefore the vertical uprights are heated more slowly than the central tube. In fact, hiding the signs of engagement with the covering elements is an operation that negatively affects the outflow of air from the engagement points of the components and is also an operation that involves additional time and implementation costs.

[0016] The object of the present invention is to provide an electric heating device with open structure and power regulator that allows to overcome all the above problems and involves other advantages that will be apparent from the following description. SUMMARY

[0017] According to the present invention, an electric heating device with open structure and power regulator is implemented. In the absence of a heat transfer liquid (as a non-limiting example, water, water mixtures, ethylene glycol and / or others), the electric heating device according to the present invention uses a constant power heating cable (CPC) whose power is preferably in the range of 10 W / m to 80 W / m. The device is characterized by having a uniform heat distribution and a fast assembly at all its points, since the CPC is inserted following the shape of the core profile or profiles and / or covering elements that make up the device (i.e. along the extension in the direction of greater extension) with a continuous way throughout their length, avoiding the engagement of several portions of the cable. The CPC is then inserted into the structure of the device, which is defined as open structure, i.e. it allows the passage of hot air from the inside to the outside and the entry of cold air. The openness ensures the ability of the structure of the invention to adapt to expansions and contractions due to thermal variations. This open structure Alsoallowing the use of various different materials with different coefficients of thermal expansion, always and in any case ensuring the spacing between the elements, to prevent the obstruction of the slots through which the air passes, and the consequent mutual pushing of the components, which would generate deformations and / or cracks. Among the various materials used to make the structure, as a preferred but non-limiting or constraining example, it is made of stainless steel. The tolerances between the various components of the structure and therefore the space between them are also evaluated according to the final surface finish, so as to prevent the thickness of the surface itself (as a non-limiting or constraining example, the paint) from hindering the passage for the air and the slots with the characteristics just described.

[0018] The open structure thus comprises one or more core profiles, inside which one or more CPCs are placed, or several identical CPCs are placed, and one or more covering elements that cover the core profiles and the CPCs and implement the open structure. In various embodiments, the open structure has an aesthetic appearance that is flat, circular, rectangular and / or other shapes, obtained by applying to the structure of the core profiles a set of said covering elements, which are shaped "plates" (i.e. as a non-limiting or constraining example, the elements can be metal and pressed, cold-rolled, hot-rolled, etc.), designed to obtain a mutual approach in millimetric precision (dimensional error less than 1 mm), thus ensuring the coplanarity between all the elements. Between the core profiles and the covering elements, direct contact surfaces are generated that allow the exchange of heat by conduction. In particular, the heated CPCs in contact with the core profiles heat them by conduction, then the contact surfaces between the core profiles and the covering elements ensure the transfer of heat again by conduction to the elements that follow. In materials such as stainless steel, the conduction allows a faster and more efficient propagation (achieving higher temperatures) with respect to that obtained by convection (i.e. heating only the internal air, thus also heating the covering elements). The presence of the contact surfaces formed on the entire length of the core profiles and the covering elements therefore ensures a faster, more uniform distribution of heat and its perception outside the heating device.

[0019] In compliance with European and American laws, the CPCs inserted inside the device are directly wired to the electrical network and / or to the control unit that manages the switching thereof, without the need to use power cables. The wiring operations implemented between the CPCs and the electrical network or between the CPCs and the control unit are carried out by means of seals, tear-resistant sealing elements and / or torsion-resistant sealing elements, crimped sword-shaped terminals (i.e. pinched, narrowed and deformed to remain in a locked position) and / or electrical terminals on the wires and connectors, which are considered obvious and known to the person skilled in the art of the field of application of the present invention; therefore, a detailed description thereof will be omitted.

[0020] The open structure of the electric heating device has one or more fasteners (fixed to the wall and / or to any other support on which the device is installed) which have both a structural function, which bears the load of the device, and a function which provides a protected and hidden passage for the CPCs to reach the built-in wall and to be connected with the electrical network or with the control unit. Therefore, the CPCs placed inside the core profiles and / or covering elements are led out directly from the one or more fasteners of the device (without interruptions and / or intermediate connections), thus allowing the electrical connection at one or more socket points based on the installation requirements. In this way, the electrical connection with the electrical network or with the control unit remains hidden inside the built-in wall. Therefore, the open structure comprises a suitable empty area passing through the fastener, in which the end of the CPCs not used to form the electrical connection can be bent.

[0021] In the embodiment in which the open structure is of the "ladder" type (i.e. the most classic form of realization of the towel warmer, which is made up of two longer perimeter elements and various central elements connected with the first two, forming right angles), the device can have an even number of central elements (whether these are core profiles and / or covering elements), in such a way that the CPCs inserted with a coil arrangement have a starting point and an end point arranged along the same perimeter element (both connectable to the electrical network or to the control unit). However, when there is an odd number of central elements, the CPCs have a starting point and an end point on two different perimeter elements (both connectable to the electrical network or to the control unit). The presence of the starting point and end point of the CPCs on the same perimeter element allows two possible points of electrical connection of the device along the same vertical line, so that by rotating the device by 180° on a plane parallel to the support on which it is intended to be installed (for example, the wall), the connection can be made in the lower right and in the upper right, or in the lower left and in the upper left, in all four cases maintaining the aesthetic configuration of the device unchanged. Since the electrical connection with the control unit and / or with the electrical network is realized in situ (i.e. at the time of installation and at the installation site), the device can also be rotated by 90° or by 270° (for example, with a horizontal arrangement) or by any other angle based on the customer's preferences, parallel to the plane of the support. The possibility of connecting the CPCs at one of the two points along the perimeter element, and the possibility of keeping the control unit (coupled in situ) in a straight position in any case, instead of being connected to the device with rigid, unique parts (for example, a single press-formed profile), allows it to have maximum flexibility in the installation (i.e. the possibility of personalized positioning).

[0022] In several embodiments like the one described above, the device of the present application ("ladder" with two long perimeter elements to which various central elements are coupled) has central elements and perimeter elements whose internal dimensions allow the passage of a CPC several times / or of several CPCs. As a non-limiting or non-restrictive example, the passage of the CPCs is made in the form of a coil, starting first from one side and, on the second passage or with the second CPC, starting from the other side. Other possible arrangements of the single CPCs provide for the entry of the CPC into a central element, its extension within the entire element, the "U" bend at its end and, once it has passed twice in the tube, its return into the same element, in which the second passage takes place; the CPCs are arranged in the same way in all the central elements, noting - after the completion of one passage in the last central element - so as to then be able to extend the CPCs within the entire length of the perimeter elements that the CPCs have not yet crossed.

[0023] All the possible configurations (described and not described) have the purpose of avoiding the appearance of cold zones on the central elements and / or on the perimeter elements. The increased internal dimensions of the elements that make up the open structure are achieved, in compliance with the inductance limits of the CPCs between two adjacent CPCs (or between two adjacent branches of the same CPC), preventing the occurrence of electromagnetic interference problems.

[0024] The described features of the present application therefore allow the manufacture of a dry electric radiator with a structure that can easily adapt to various support and spatial geometries, with variable and personalizable shapes, without limitations related to operating efficiency, and allow the realization of a structure with considerable aesthetic value. The possibility of using the entire surface of the electrical device as a heat dissipation surface allows devices of various sizes (height and width preferably in the range between 25 cm and 210 cm, and minimum internal dimensions of the tubular elements preferably between 8 mm and 100 mm) and capable of performing the function of a towel dryer by providing a power preferably between 5 and 600 W, or of a radiator function capable of providing a power preferably between 600 W and 2500 W.

[0025] The high power provided allows the generation of high temperatures within the device, thus bearing high internal pressures. These pressures increase when clothes, towels or other elements that are usually still wet are placed on the central elements of the device.

[0026] To overcome this problem, the solution proposed by the present invention is to make a dry electrical device with an open structure that allows the instantaneous dissipation of the internal pressure and also has greater passage of hot air towards the outside. As already anticipated, this open structure is achieved through a core profile and a covering element. As a non-limiting or non-restrictive example, this core profile is a pressed sheet profile with an open section, which is "L" shaped, "C" shaped and / or has another form.

[0027] The core profile and the covering element are coupled together through various types of coupling systems, such as:

[0028] - through a system of pressing two pressed sheets;

[0029] - a "latch" system, in which a latch is used, i.e. an element with a geometric shape and section (preferably a thin sheet with an open section, such as "L" shaped), to be able to be inserted between the covering element and the core profile through manual pressure and / or using mechanical tools (as a non-limiting or non-restrictive example, a clamp), and which keeps the element and the profile in the desired position (the position achieved by the final configuration of the structure) through mechanical interference, i.e. via pressure, via traction, by triggering a push-pull mechanism, by triggering a lever mechanism and / or the like;

[0030] - a joining system with tabs and slots, in which a protrusion ("tab") on the core profile and / or the covering element is fitted inside a slot (a slit with a thickness and a geometric shape that allows the tab to be inserted and joined).

[0031] According to one embodiment of the present invention, the device and its open structure have the appearance of a single profile (as a non-limiting or non-restrictive example, its section can be rectangular, circular, semicircular and / or other shapes).

[0032] According to another embodiment of the present application, the covering elements are a coupling plate, a front plate and a perimeter covering element. In this embodiment, the coupling plate is a plate with various shapes, on which fasteners are connected that anchor it to the support. As an alternative, the front plate is an element with minimal aesthetic appearance, which, as a non-limiting or non-restrictive example, can include inserts made of precious materials, one or more mirrors and other items. In the part of the front plate opposite the coupling plate, a core profile is positioned, inside which the CPC is arranged. The perimeter covering element is finally an assembly of one or more elements that allows to obtain a frame, thus creating a distance cavity designed to create a chimney effect, in which hot air exits from the upper part and cold air enters from the lower part. In this embodiment, the assembly of the structure of the device provides for the installation of the core profile on the surface of the front plate facing the support, for the coupling of the perimeter covering element and the coupling plate together and, finally, for the coupling of the front plate to the coupling plate placed on the support.

[0033] In several embodiments, the various components of the open structure can be fixed together by riveting, where the size of each rivet is designed with tolerances to support the thermal deformation of the various elements.

[0034] As already mentioned, another innovative aspect of the present application includes the presence of a power regulator. The power regulator is connected to a suitable probe for measuring the temperature inside the device.

[0035] In one embodiment of the present application, the power regulator is also provided with one or more connections with a thermostat or any type of ambient temperature sensor.

[0036] The power regulator therefore involves the management of the energy flow using inverter technology up to the set energy level. In fact, the device provides for the division of the maximum power rating into various operating power levels associated with the same number of temperature levels (the number of which is variable and personalizable). The power regulator electronically cuts off the excess energy, preventing it from being dissipated to other points with energy waste. The power regulator and, as shown, the temperature regulator keep the energy flow constant, resulting in energy consumption. To reach the desired temperature, the electronic management avoids having to operate the electric heating device at maximum power in the switching time interval, thus allowing compliance with the availability of electrical energy while using multiple electrical appliances. The software of the power regulator therefore manages the electric power by means of a cut wave that throttles the absorbed electric power in order to significantly limit the electromagnetic interference, thus allowing more space in the hardware of the power regulator and control unit for the insertion of safety components required by European and American laws and / or other certifications (as a non-limiting or non-restrictive example, fuses in order to protect the electrical device from possible short circuits and overloads).

[0037] The advantages offered by the present application are evident from the description thus far and will become even more apparent thanks to the annexed drawings and the relatively detailed description. BRIEF DESCRIPTION OF DRAWINGS

[0047] The present application uses a dry electrical energizing process, which comprises the insertion of single heating elements (constant power cables CPC 10) distributed along the entire structure 200 of the electrical heating device 100, which can be a towel dryer and / or radiator, without the presence of heat transfer liquids inside.

[0048] The electrical system and structure 200 of the electrical heating device 100 allow to obtain various advantages and overcome many technical problems:

[0049] - ensure the speed with which the maximum temperature of the heating elements of the CPC 10 is reached, so that the heat can be perceived in a few minutes;

[0050] - ensure a uniform heat distribution along the entire radiating surface and prevent cold spots from remaining in products with large dimensions or specific shapes (for example, wavy, angular, etc.);

[0051] - prevent energy waste and allow the input electric power to be modulated by means of a suitable power regulator 111 and, consequently, the thermal regulation. In particular, the software 112 installed on the power regulator 111 allows to cut off the input electric power and the related waveforms, also allowing the use of the electrical heating device 100 at low temperatures, without changing its aesthetic and dimensional characteristics, and in any case fully complying with the current laws. The software 112 then throttles the electric power absorbed in order to limit the electromagnetic interference;

[0052] - eliminate the annoying noises related to the thermal expansion and contraction of the materials or materials that make up the structure 200 itself of the dry electrical heating device 100;

[0053] - prevent the generation of high and dangerous pressures inside the electrical heating device 100, which has an open structure 200, i.e. which allows the outflow of air;

[0054] - increase the efficiency of perceiving the heat in the vicinity of the electrical heating device 100, thanks to the chimney effect that can be generated by the open structure 200, by expelling hot air and sucking in cold air;

[0055] - have an aesthetically valuable electrical heating device 100, with the joint marks of the various components hidden thereon (thus pointing to the support 1 on which the electrical heating device is installed) or appropriately shown as a design choice (but not a structural requirement);

[0056] - with an electric heating device 100 having a structure 200 which can have various forms, not only straight, but also curved and / or wavy in all spatial directions (as non-limiting or non-restrictive examples, curved both in and out of the plane parallel to the support 1 to which the electric heating device 100 is connected);

[0057] - with an electric heating device 100 which can be quickly assembled, not necessarily requiring the execution of welding, but also allowing a simple manual assembly in which the CPC 10 is manually inserted into the various components and elements of the structure 200, which are then assembled together by means of an engagement system or "latching" system with slots and tabs (i.e. components that do not require the execution of welding operations, thus not requiring the execution of welding or the use of slow and / or complex tools);

[0058] - with an electric heating device 100 which allows the passage of the heating element CPC 10 within its structure 200 according to various paths and arrangements (as non-limiting or non-restrictive examples "coil" arrangements) and within the wall coupling 203 which extends to the built-in wall 104 in which the heating element CPC 10 can be wired. The possibility of passage of the heating element CPC 10 within the wall coupling 203 not only allows to have a more valuable appearance, preventing the display of electrical cables and / or other elements for hiding the same, but also allows to save economic costs by using the same element (wall coupling 203) both for the structural purpose of carrying the load of the electric heating device 100 and for hiding and protecting the heating element CPC 10.

[0059] In several embodiments of the present application, the CPC constant power heating cable 10 is a cable with double wire per meter with the same power. The two wires (one for the positive pole and one for the negative pole) are wound with two insulating sheaths interrupted at regular intervals to ensure that the heating spiral wire (as a non-limiting example of nickel-chromium alloy) wound on the sheaths can have contact points with the wires at regular intervals. The wires, the sheaths and the heating wire spiral are all wound with an insulating material such as silicone.

[0060] In several embodiments thereof, the CPC cable 10 can be equipped with an external metal mesh to ensure an increase in mechanical protection and earthing of the cable.

[0061] In other embodiments of the present application, the CPC cable 10 is self-regulating. A self-regulating CPC cable 10 is a cable with two conductors that feed an electrically conductive graphite inner core. The graphite particles make up a number of parallel connections between the two wires. When the heating cable cools down, the core microscopically shrinks and the graphite makes up a number of connections between the wires. The passage of current generates heat and at the hottest points it microscopically expands, thus breaking several electrical contacts. Increasing the electric heating element reduces energy dispersion until a thermal equilibrium is reached between the heat loss and the heat power generated by the cable. Very high temperatures ensure that the microscopic expansion of the core almost interrupts all the contacts. One such self-regulating CPC cable 10 is not overheated and does not burn, but is automatically protected by the mechanism just described. In this embodiment of the present application, the function of the power regulator is fully or partially performed by the same self-regulating CPC cable 10, according to what has just been described.

[0062] The structure of the electric heating device 100 and the nature of the connections, cables, heating elements and hardware used are waterproof, even when it has to enter said open structure.

[0063] The structure 200 is adapted to allow the passage of air to accommodate expansions and contractions due to thermal variations and comprises:

[0064] - one or more core profiles 201 through which one or more CPCs 10 pass inside and / or the CPCs 100 pass inside said core profiles 201 one or more times;

[0065] - one or more covering elements 202 adapted to cover several core profiles 201 and said CPCs 10 to achieve an open structure that allows the escape of hot air and the entry of cold air and which, when combined together, are coplanar to produce an aesthetic effect of surface continuity; said core profiles 201 and / or said covering elements 202 have straight, curved and / or wavy shapes both in and out of the plane parallel to the plane of the support 1 on which the electric heating device 100 is installed;

[0066] - one or more contact surfaces 205 between said core profiles 201 and said covering elements 202 that allow heat exchange by conduction, thus accelerating the distribution of heat and increasing the amount of heat that reaches said outer covering elements 202;

[0067] - one or more wall couplings 203 that have a load-bearing structure function adapted to couple the structure 200 to the support 1 and also a protection function such as hiding said CPCs 10 that pass inside it; said CPCs 10 pass inside said core profiles 201 and said wall couplings 203 in order to reach the built-in wall 104 in which the CPCs 10 are connected to the electrical network or control unit 110;

[0068] - from the inside of the structure 200, in front of the wall coupling 203, one or more folding spaces 210 for the unused end of the CPC 10 for electrical connection are folded in this folding space 210.

[0069] The open structure 200 is initially intended to meet the needs described above and is strictly dependent on the technical practice of inserting the CPC cable 10 inside it. The synergy between the open structure 200 and the practice of inserting the heating element CPC 10 inside it, as described above, allows to achieve the advantages described above, which would not be possible if one of the two elements (structure 200 or heating element CPC 10 inserted therein) were not present.

[0070] In several embodiments of the present application, the covering element 202 is a pressed profile with open section (for example, "C" section, "L" section, "IPE" type and / or other forms, i.e. with non-closed section). The pressed profile can be obtained with various types of materials, as a non-limiting or non-restrictive example, steel, aluminum, coated with plastic material and / or other materials and / or aluminum with different finishes.

[0071] In several embodiments of the present application, the covering element 202 can be assembled together and / or with the core profile 201 by crimping together, to create a continuous aesthetic effect.

[0072] In several embodiments of the present application, the covering element 202 can be assembled together and / or with the core profile 201 by "latch" joints, using an element called latch 207, consisting of a plate with a geometry and section to allow locking with the covering element 202 and / or with the core profile 201 by mechanical interference (i.e. by creating a mechanical constraint by compression, traction and / or creating a push-pull mechanism). The latch 207 is positioned by the pressure exerted by hand and / or mechanical tools.

[0073] In several embodiments of the present application, there are tabs 208 and slots 209 that cooperate with each other in order to keep the covering element 202 and / or the core profile 201 locked in the desired position (i.e. in the final position configured as designed, which ensures the immobility of the individual elements and the solidity of the structure 200).

[0074] The coupling of the tabs 208 and the slots 209 supports possible torsions and allows the device 1 to have flexibility in the process of installation on the support 1, even in the case of very irregular supports and not completely flat (as a non-limiting or non-restrictive example, rural brick walls, not perpendicular walls, etc.).

[0075] In various embodiments of the application, the core profile 201 and / or the covering element 202 have straight, curved and / or wavy shapes both in the plane parallel to the support 1 and out of the plane.

[0076] The power regulator 111 is a device that forms part of the control unit 110. The control unit 110 has an interface with buttons, screen, lights and, in several embodiments, also a microphone and a loudspeaker. In addition to including an electronic board with the power regulator 111, the control unit 110 also includes an electronic logic board 113 adapted to receive the inputs obtained through the interface, to provide outputs on the screen, lights and loudspeaker and to communicate with said power regulator 111, thus ensuring that the electric heating device 100 consumes the requested power and reaches the temperature indicated on the interface.

[0077] In several embodiments of the application, the power regulator 111 and the electronic logic board 113 are several meters or tens of meters apart. In these embodiments of the application, the power regulator 111 is connected to the electronic logic board 113 through an electrical connection with the cable (the electrical connection with the cable is considered a trivial and known implementation for those skilled in the art of the application field, therefore it is not described in detail here) and / or through a wireless connection, when each is equipped with wireless communication devices.

[0078] In several embodiments of the application, said electronic logic board 113, as a non-limiting or non-restrictive example, implemented through SMD (Surface Mount Device) technology, has a limited thickness, preferably less than 1 cm, and has electronic components that are not affected by the temperature of the electric heating device 100, thus being able to be installed on the electric heating device 100 itself (as a non-limiting or non-restrictive example, inside recessed slots and / or holes arranged in the core profile 201 and / or in the covering element 202).

[0079] Both the electronic logic board 113 and the power regulator 111 of the control unit 110 are covered with a protective box and / or insulating material to ensure fire and water protection.

[0080] The control unit 110 is housed in the built-in wall 104 and has an access through which the control unit 110 can be directly coupled to the wall coupling 203 of the electrical heating device 100 of the structure 200, allowing the electrical connection with the electrical wires of the CPC 10 that come out from said wall coupling 203. Said built-in wall 104 is a recessed slot in the wall that acts as a support 1 for the electrical heating device 100, in which an electrical box is located in which the connection with the electrical grid can be achieved. The wall coupling 203 comprises a hole, a thread and a threaded tube formed on the core profile 201 and / or on the covering element 202 of the structure 200 of the electrical heating device 100, the threaded tube being preferably a cylindrical element with internal thread, so as to be able to be screwed in and hide the CPC 10 that passes through it, in order to reach the built-in wall 104 and be directly connected with the control unit 110 or with the electrical grid. Said wall coupling 203 also has a structural support function, firmly connecting the electrical heating device 100 and said built-in wall 104. The power regulator 111 is connected to a probe for measuring the temperature inside the electrical heating device 100.

[0081] In one embodiment of the application, the power regulator 111 is provided with one or more connections with a thermostat, a timer thermostat or any type of ambient temperature sensor.

[0082] The power regulator 111 manages the energy flow with inverter technology until the set energy level is reached. The control unit 110 in fact allows the selection between various power levels (and temperature levels), the number of which is personalizable, for operating the electrical heating device 100. The power regulator 111 electronically cuts off the excess energy, preventing it from being dissipated to other points, thus causing energy waste. The electronic management operated by the power regulator 111, in order to reach the desired temperature, avoids the need to operate the electrical heating device 100 at maximum power in the switch-off interval, thus allowing compliance with the availability of electrical energy while using multiple electrical appliances. The power regulator 111 has a software 112 that manages the electrical power by cutting the wave.

[0083] In one embodiment of the application, the control unit 110, which communicates with a wireless protocol, can be accessed and managed by means of a mobile device, as a non-limiting or non-restrictive example, such as a smartphone, a tablet, a PC and / or other devices.

[0084] The absence of heat transfer liquid (as a non-limiting or non-restrictive example, a mixture of water and glycol) inside the electric heating device 100 allows its installation in any position and orientation (think of the device rotating in a plane parallel to the support on which it is intended to be installed) without performance limitations, even in large-size products. The electric heating device 100 according to the present application can be installed oriented in any direction (as a non-limiting or non-restrictive example, in a plane parallel to the support 1 on which the wall must be installed), the CPC 10 coming out of the two wall couplings 203, can be connected directly with the electrical network and / or with the control unit 110 from the desired side, and can be reinserted inside the structure 200 from the unused side.

[0085] Another advantage of the electric heating device 100 of the present application and of its electrification system is also the flexibility of possible applications in non-linear structures, which is generally not allowed by traditional methods. The power regulator 111 in the radiator for heating implements the principle of optimization of energy use, since it allows an efficient management of the power used by controlling the consumption and a higher energy efficiency.

[0086] Based on the power delivered by the CPC 10 and its size, the electric heating device 100 can have a towel dryer function by using a CPC 10 that delivers a power between 5 W and 600 W, and / or it can have a space heating function by using a CPC 10 that delivers a power greater than 600 W.

[0087] In several embodiments of the present application, the electric heating device 100 has a uniform heat distribution at all its points, the core profile 201 and / or the covering element 202 having internal dimensions that allow multiple passes of the CPC 10 and / or multiple CPCs 10, in compliance with the inductance limits of the CPC 10 preventing the occurrence of electromagnetic interference problems.

[0088] The present application will now be shown as a non-limiting or non-restrictive example with reference to the attached drawings, which show several embodiments related to the inventive concept.

[0089] With reference to Figure 1 , a perspective view of the electric heating device 100 is shown, as well as several connection operations with the control unit 110 according to the present application. In Figure 1 , as in the following description, an embodiment of the present application is shown, which is considered the best so far.

[0090] Said electric heating device 100 comprises said CPC constant power heating cable 10, the power of which ranges from 10 W / m to 80 W / m, inserted in its structure 200 in a continuous manner, following the shape of one or more core profiles 201 and / or covering elements 202 that make up the structure of this electric heating device, throughout its length and without the presence of a heat transfer liquid, i.e. along the extension in the direction of greater extension, preventing the joining of several portions of the cable. This electric heating device 100 has a quick assembly, said CPC 10 being directly wired connected (i.e. electrically connected) with the electrical grid and / or with the control unit 110 that manages its switching on and off, without the need to use a power cable. Said core profiles 201 and / or covering elements 202 can have a straight (as shown in Figure 1 Fig. 1), curved and / or wavy (as shown in Fig. 2) shape, both in the plane parallel to the support 1 on which the electric heating device 100 is installed and out of the plane. Said electric heating device 100 can be installed oriented in any direction, said CPC 10 protruding from two wall couplings 203 (as shown in Figure 1 Fig. 3, where the number of central core profiles 201 is even, the CPC 10 protruding from two wall couplings 203 on the same perimeter element made up of a plurality of covering elements 202), can be directly connected with the electrical grid and / or with said control unit 110 from the desired side (according to the space and electrical grid requirements of the user who installs the device) and can be reinserted in the structure 200 from the unused side.

[0091] Said control unit 110 has an electronic logic board 113 that manages the inputs and outputs on the user interface and has a power regulator 111 with software 112 suitable for controlling the electric power by means of a cut wave that throttles the absorbed electric power in order to keep the energy flow towards the CPC 10 constant according to the desired temperature, prevents the closing and opening cycles at maximum power and allows the simultaneous use of multiple electric appliances in compliance with the availability of the electrical power.

[0092] In the perspective view shown in Figure 1 Fig. 4, imagining the desired connection of the electric heating device 100 with the control unit 110 located on the left side, it is sufficient to rotate the electric heating device 100 by 180° on a plane parallel to the wall on which it is desired to install the device and on the left side two wall couplings 203 will be found available. If it is desired to arrange the electric heating device 100 according to a specific direction different from the vertical direction (as shown in Figure 1 Fig. 5), the same reasoning can be made, where it is sufficient to rotate the electric heating device 100 by the desired angle. In each of the cases described above, the operation of the device is not negatively affected in any way.

[0093] Figure 1Also shown is the possibility of connection through the wall coupling 203. The following is shown in circled details: the horizontal control unit 110 with display, the electrical box that can contain the connector 105 or the wireless acquisition and transmission unit 106, and the vertical control unit 110, all inserted into the built-in wall 104.

[0094] The central circled detail shows that when the control unit 110 is remote and therefore far from the electric heating device 100, the CPC 10 is connected directly to the connector 105 in the electrical box in the built-in wall 104, then through this connector 105, through the use of an electrical cable, wiring with the control unit 110, which can be horizontal or vertical, with or without display, and with another technology, as already discussed. The case shown in the central circled detail provides that, after any electrical connection, the built-in wall 104 with the relative electrical box is covered with a layer of paint, concrete and / or another material / element, allowing the threaded pin to protrude outward, into which the wall coupling 203 is inserted. In this way, the connection wall coupling 203 - built-in wall 104 has a load-bearing function for the electric heating device 100.

[0095] Furthermore, when the control unit 110 is remote and uses a wireless communication protocol, the CPC 10 is connected directly wired to the wireless signal acquisition and transmission unit 106 included within the built-in wall 104.

[0096] With reference to Figure 2 , a sectional perspective view of the control unit 110 is shown.

[0097] The control unit 110 is arranged with a series of connectors for electrical cables in order to allow connection to the electrical network and to the CPC 10. In the detail shown, the power regulator 111 and its software 112 and the electronic logic board 113 are observed. Figure 2

[0098] The electric heating device 100 has a power regulator 111, shown in detail in Figure 2 , which is installed inside the built-in wall 104. Behind the interface with the display and the buttons of the control unit 110, the electronic logic board 113 is positioned and connected with the power regulator 111 through an electrical cable. The power regulator 111 has software 112 suitable for controlling the electrical power through a cut wave that throttles the electrical power absorbed in order to keep constant the energy flow towards the CPC 10 according to the desired temperature maintenance, prevents the closing and opening cycles at maximum power, and allows the simultaneous use of multiple electrical appliances in compliance with the availability of electrical power.

[0099] With reference to Figure 3 ​, a front view and a cross-section of the electric heating device 100 are shown. Figure 3 The electric heating device 100 shown has both a core profile 201 and a covering element 202, whose shape presents various curvatures on a plane parallel to the support 1 as a brick wall. Figure 3 The "coil" arrangement of the CPC 10 within the electric heating device 100 is also shown by cross-section.

[0100] With reference to figure 4, an exploded view of the structure 200 of the electric heating device 100 according to the present application is shown Figure 4A , as well as various details Figure 4B , Figure 4C , Figure 4D , Figure 4E .

[0101] It is observed in figure 4 that the structure 200 implements an electric heating device 100 of the towel dryer type, in which the core profile 201 is of 12 bent tubes arranged parallel to each other, the "coil" positioning within the CPC 10 being as shown in Figure 4B , and two core profiles 201 are press-shaped into a "C" and are perforated so as to allow the insertion of the 12 bent tubes. On each of the two press-shaped "C" core profiles 201, two covering elements 202 are installed. Said covering elements 202 have tabs 208 and slots 209 which cooperate with each other so as to keep said covering elements 202 locked in the desired position, i.e. covering the core profile 201, and in the proper position so that the joint line between one covering element 202 and the other covering element 202 is oriented towards the support 1 and is thus hidden.

[0102] Figure 4A The presence of a closing cap 204 welded to the end of the covering element 202 is also shown. The welding of the closing cap allows the surface treatment to be carried out, as a non-limiting or non-restrictive example of galvanization.

[0104] Figure 4C The detail shown illustrates the bent tubular core profile 201 locked through said slots 209 on the tabs 208 of the press-shaped "C" core profile 201.

[0106] In summary, Figure 4EThe details shown illustrate the cross-sections of the cover element 202 and the pressed “C” shaped core profile 201 during and at the end of the installation process. Figure 4E The contact surface 205 (black dashed line) is also shown, which allows heat exchange through conduction between the pressed “C” core profile 201 and the cover element 202.

[0107] Referring to Figure 5, a rendering of the electric heating device 100 having the structure 200 is shown. Figure 5A ).

[0108] exist Figure 5A In the diagram, it can be observed that the structure 200 of the electric heating device 100 includes a rectangular covering element 202 and a control unit 110, which is directly connected to the structure 200 via the wall connector 203.

[0109] Figure 5B The details show the cross-section of the central cover element 202 of the structure 200. It is worth noting that this cross-section is achieved by crimping two cover elements 202 (performed at the point with the circular arrow), and this cross-section allows two internal spaces for the passage of two CPC 10 or for the passage of the same CPC 10 twice. Figure 5B The contact surface 205 between the CPC 10 and the cover element 202 is also shown.

[0110] Figure 5C The details show the bottom part of the central covering element 202 of the structure 200, on which four slots 209 can be seen.

[0111] Figure 5D The details show the slot 209 of the center tab 208 of the first core profile 201 inserted into the center cover element 202 of the structure 200 (as shown in the image). Figure 5C As shown in the figure, the other two protruding tabs 208 lock their central covering element 204 in place to prevent it from sliding along the lower tab 208.

[0112] In addition, the following Figure 5D A second core profile 201 is shown arranged above the first core profile 201 and the center cover element 202, wherein the slot 209 of the center cover element 202 (in) Figure 5C (As shown in the figure) accommodates the central protrusion 208. Figure 5D The lower details show that the second core profile 201 prevents the center cover element 202 from moving in the direction that causes the center tab 208 to exit the slot 209 (e.g., Figure 5CThe contact points between the central tab 208 and the slots 209 create contact surfaces 205 (not shown in the figures).

The structure 200 of the electrical heating device 100 comprises covering elements 202 with a square cross-section. In the detail shown in figure 6B, one observes a portion of a side covering element 202, where there are the following parts (starting from the inside to the outside): a first core profile 201 with a square section, a second core profile 201 with a "C" shape. Figure 6B shows a covering element 202 which is "U" shaped, separated and constrained from the second core profile 201 by means of a latch 207 (shown in figure 6B with darker filling). In figure 6B, one also observes that the latch 207 is inserted diagonally inside the "U" shaped covering element 202 and then bent (bending arrow) so as to enter completely therein. In order to cover the latch 207, another flat covering element 202 is inserted (the upper covering element 202 in figure 6B). Figure 6B also shows a third tubular core profile 201 connected inside the first square core profile 201 and its relative covering element 202. Figure 6B finally shows two contact surfaces 205 (with two black dashed lines) which are created between the core profiles 201 and between the covering elements 202, which facilitate the heat exchange by conduction.

[0115] With reference to figure 7, a rendering of an electrical heating device 100 with the structure 200 is shown (figure 7A). The electrical heating device 100 shown is aesthetically configured as a single tube with a semi-circular cross-section, with two wall couplings 203.
