Abstract
Description
- The present invention relates to a turbulator component arranged to be inserted in a pipe for conveying combustion fumes of heating apparatuses, as well as a heating apparatus comprising one or more of these turbulator components.
- Some heating apparatuses, such as for example home heat generators and the like, supplied for example with pellets or other fuel, include, as it is known, heat exchanger, sometimes also known as a monobloc, which comprises a plurality of exhaust ducts or pipes, through which the combustion fumes are passed.
- The aforementioned exhaust pipes are housed inside a chamber, with a carrier fluid, usually water, being circulated therein.
- In known heating apparatuses, elements called turbulators are normally inserted inside the exhaust pipes, whose function is to transform the flow of combustion fumes from laminar to turbulent.
- The turbulators in fact slow down the flow of combustion fumes, improving the speed of heat transfer from these fumes to the carrier fluid and making heating by the exchanger more homogeneous.
- The turbulators of the type currently used are rigid and arranged along a respective substantially straight exhaust pipe.
- To clean the exhaust pipes with a respective tool, such as a brush, it is necessary to remove the turbulator and for this purpose one or more special technical inspection openings are required, which can be usually accessed by removing at least one cover panel arranged to conceal the technical opening.
- With the aim of removing the cover panel, which makes it possible to access to the technical opening, tools are generally required, especially in case the removal of the panel exposes electrical parts of the apparatus.
- Moreover, if one wants to reach the turbulators, tools for unscrewing/tightening are usually required for intervening on the technical openings. In this regard, the technical opening must be closed tightly once the respective panel has been repositioned, this requiring adequate tightening force/torque applied by a tool.
- An object of the present invention is to provide a new turbulator component for heating apparatuses.
- Another object of the present invention is to provide a turbulator component that can be easily and quickly inserted/removed into/from a pipe for conveying combustion fumes of any shape.
- Another object of the present invention is to provide a turbulator component simple and easy to be obtained.
- Another object of the present invention is to provide a new heating apparatus.
- Another object of the present invention is to provide a heating apparatus in which it is possible to clean the pipe or pipes for conveying combustion fumes easily and quickly.
- Another object of the present invention is to provide a heating apparatus in which it is possible to easily inspect respective zones of conveyance of combustion fumes.

turbulator component 1 has been illustrated which is designed to be inserted in a pipe for conveyingcombustion fumes 2 of a heat exchanger of a heating apparatus 3, such as a stove, a boiler or the like, if desired for home use. - This
turbulator component 1 comprises at least a folding or flexible element or switchable indifferent trims 4 on which a plurality, for example any number between three and ten or more, if desired six, seven or eight projecting elements or protuberances orflow deflector elements 5 are mounted, which designed to slow down and divert the flow of combustion fumes so as to transform the flow of the latter from laminar to turbulent, thereby improving the speed of heat transfer from these to a carrier fluid, such as water or air and making it more homogeneous heating by the respective exchanger. - The
protruding elements 5 are each mounted at a respective portion of the length of theflexible element 4, so that theprotruding elements 5 are distributed along the extension or, preferably, along the entire extension of the folding or flexible or switchable indifferent trims element 4. If desired, one or both of theend sections flexible element 4 can be free of protruding elements. Preferably, the projectingelements 5 are fixed on theflexible element 4, so as not to slide over the latter and therefore in a position substantially fixed with respect to the length of theflexible element 4. - More particularly, the foldable or flexible or
switchable element 4 can be bent or flexed or switched, elastically or not, between several trims so as to vary the arrangement of the projectingelements 5 one with respect to the other, thereby making it possible to insert or remove theturbulator component 1 into/from curved sections or mutually inclined sections of conveyingpipes 2 of heating apparatuses 3. - Preferably, the folding or flexible or
switchable element 4 can be folded or flexed or switched, elastically or not, at a plurality of portions thereof. - If desired, the folding or flexible or

flexible element 4 is not to be intended as side, considering for example that in the case of a chain no faces are provided with such meaning. - If desired, the projecting
elements 5 are mounted on theflexible element 4 so as to protrude from a first side of the same to a greater or equal extent with respect to a second side, if desired opposite to the first. - In this regard, some projecting

pipes 2 can have a straight configuration or even, as shown in the figures, a L-shape, with a lower mainvertical section 2a and an upperterminal section 2b inclined or orthogonal with respect to the mainvertical section 2a. Clearly, one or more of the conveyingpipes 2 can have a different configuration, if desired curved. In this case, in order to insert aturbulator component 1 into a conveying pipe, it is necessary to bend or flex or switch, for example at the joint sections of the links of a chain, the respective flexible element in order to make it to cross an elbow or bent section of a respective conveyingpipe 2. - The apparatus 3 or the
main side wall 9 further delimits at least oneopening 14 for inserting or removing theturbulator component 1 into/from the conveyingpipe 2. If desired, theupper end section 2b of one or each conveying pipe opens into one or a respective opening for inserting or removing 14. - Advantageously, the opening for inserting or removing 14 opens at the top of the
combustion chamber 6, thisopening 14 being also designed to allow the combustion fumes to entry into a respective conveyingpipe 2. If desired, a plurality, for example four of openings for inserting or removing 14 are provided, each for a respective conveyingpipe 2 and each delimited at a respective top section of the combustion chamber. - The conveying
pipes 2 can then open into acollector area 15, if desired below or above and/or on the side of thecontainment chamber 8 and a respectivefirst fan 16 is then provided, as well as adischarge opening 17 delimited by one of the walls delimiting thecollector area 15, for example from the intermediate orexternal wall 10, so that the combustion fumes can be suctioned from thecollector area 15 towards the outside of the latter or of the apparatus 3. Of course, thefirst fan 16 could not be present, this occurring for example in a fireplace equipped with a boiler. - According to the embodiment shown in the figures, the lower, in use, end of the conveying pipe(s) 2 is mounted on the
lower wall portion 11 and thelower collector area 15 is provided under thecontainment chamber 8 in which all the conveyingpipes 2 actually open. - The

lower collector area 15 can be delimited between alower part 9a of themain side wall 9, part of the intermediate orexternal wall 10, thelower wall section 11 and abottom wall section 19 of theframe 3a of the heating apparatus 3. - Clearly, the
containment chamber 8 and thelower collector area 15 are isolated and not in fluid communication with respect to each other. - Moreover, a
deflector 20 can be provided in thelower collector area 15, which deflector 20 is arranged in such a way as to divert the combustion fumes of the conveyingpipes 2 opening at thedischarge opening 17, so as to prevent the combustion fumes from immediately reaching thedischarge opening 17 once they have exited from these conveyingpipes 2 in thecollector area 15. - If desired, the
lower part 9a of themain side wall 9 delimiting thelower collector area 15 can be disassembled, by means of locking/unlocking means, for the inspection and possible cleaning of thisarea 15. - Thus, for example, the locking/unlocking means can comprise a
plate 21 integral with ablock 22 defining an opening or protuberance which can be engaged by means of a tool, such as an Allen key, whichplate 21 is mounted for rotation on thelower part 9a or on apanel 9b of thislower part 9a, so that theblock 22 opens into thecombustion chamber 6. - On the other hand, the
bottom wall portion 19 can have an L-shapedend 19a such as to interfere with theplate 21 in a first trim, for example vertical or with vertical length and so as not to interfere with it when it is in a second trim, for example horizontal or with horizontal length. - With such a structure, while the
plate 21 is in the first trim, if one pulls theblock 22 and therefore thepart 9a, theplate 21 hits the L-end 19a and the lower edge of theside wall 9 and it is not possible to dismount thepart 9a, while controlling the rotation of theplate 21 from the first to the second trim, by pulling theblock 22 it is possible to remove thelower part 9a and dismount it from theframe 3a for the inspection of thelower collector area 15. - In addition, the
lower part 9a can be composed ofseveral panels 9b which can be dismounted each separately from the other, for example by means of a mechanism as described above, so as to expose thelower collector area 15 for its entire extension. - Clearly, the
panels 9b are connected in a fluid sealing manner with one another, with the remaining portion of themain side wall 9 and with the L-shapedend 19a. - The heating apparatus 3 can be powered by biomass, if desired pellets or wood, but also by other fuels other than biomass, such as fossil fuels.
- In this regard, it can be equipped with a manual or automatic fuel loading system, which can open into the
combustion chamber 6 by means of asuitable loading duct 18. - The apparatus then has a
brazier 23, for example mounted on the bottom of thecombustion chamber 6. - This
brazier 23 can also delimit a plurality of small holes orslots 24, in fluid communication with a suitable source of supply of a comburent fluid, such as air. - Clearly, other arrangements may also be provided for feeding comburent fluid, for example air, into the
combustion chamber 6, such as suitable conduits opening into thecombustion chamber 6, as well as means for pushing or the like of the comburent fluid, for example one or more fans. - According to the non-limiting embodiment shown in the figures, the
brazier 23 can have a box-like shape and delimit acavity 25 opening outwards or better into thecombustion chamber 6 by means of thesmall holes 24 and then ansupply duct 26 is provided, on one side, opening into thecavity 25 and, on the other side, opening to the outside or the environment, if desired under or inside the apparatus 3. - In this regard, since the
fan 16 sucks the combustion fumes from thecombustion chamber 6, after passing through the conveying pipe(s) 2, a depression is generated in thecombustion chamber 6 which draws air into thebrazier 23 after passing in thesupply duct 26. - The
brazier 23 or at least a lower body of the same can also be removable from the drawer so that is can be easy cleaned. - The apparatus 3 can then comprise at least one component for coupling/release the
flexible element 4, if desired abracket component 27, for example a component for coupling/release the top of aflexible element 4. According to the non-limitative embodiment shown in the figures, thebracket component 27 can delimit a slot, if desired vertical 27a and open upwards, with an end portion of theflexible element 4 houseable therein, if desired a portion of alink 4d of arespective chain 4 for example at anend portion - The
bracket component 27 can be fixed, in a high or upper section, if desired an upperterminal section 2b of a conveyingpipe 2. - The coupling/release component of the
flexible element 4 can be close to or in any case accessible from one or a respective opening for inserting or removing 14. - The apparatus can also comprise a
conduit 28 for transporting a fluid, such as air, at the top of thecombustion chamber 6, whichconduit 28 can open on the front of the apparatus 3, is desired at anupper grid 29. In this regard, asecond fan 30 for sucking and pushing air within saidtransport duct 28 can be provided, so as to deliver hot air within the environment where the heating apparatus 3 is installed. - Of course, the apparatus also includes one or more motors for driving the various components, as well as a control unit.
- As will be understood, a
turbulator component 1 according to the present invention can be easily inserted and removed from a respective conveyingpipe 2, since it is possible to bend such aturbulator component 1 as desired, thus being it possible to insert it also through curved pipes and, with reference to the embodiment illustrated in the figures in an L-shaped conveyingpipe 2. - However, owing to the present invention, inspection openings are not necessary as according to the state of the art, so there is no need for tools for removing the cover panel thereof.
- It is understood that with such a solution, the maintenance of the exhaust conveying pipes can be carried out by means of a simple brush or other devices and for this purpose it would be sufficient to open the leaf or door of the apparatus, if desired to remove one or
more turbulator components 1, for example starting from theopening 14. - Amendments and variations of the invention are possible within the scope defined by the claims.
