Definitions

  • the present invention relates to a flue cleaning device, for cleaning the interior cavity of a flue of the type used with a wood burning stove or the like, comprising scraping means and support-control means of said scraping means, said scraping means being adapted, thanks to a substantially reciprocating movement of said support-control means, and consequently of said scraping means, to cause a scraping action from the walls of combustion product debris, said reciprocating movement being adapted to be either axial along axis of said flue or rotary around said axis.
  • Flue cleaning operation was highly reduced by modern civilisation, but it was not solved, at contrary it was aggravated also due to a considerable diffusion of heating systems of any kind (wood, coal, gas oil, diesel oil, natural gas, etc.). Till some time ago, when heating problem was entrusted to wood burning kitchens or stoves, the so-called “chimney sweepers” took potity upon maintenance of flues. The operation was generally made with big metal brushes, connected to more or less long handles. Flues were cleaned starting from the top, with the consequence that people had to climb on the roofs, also when weather was not fine.
  • a problem, which the device according to the invention intends to solve is to propose a new solution, substantially simple and reliable, relating to the cleaning operation of a flue, avoiding risk to operate on a roof with any conditions of weather, but allowing an operator not to have his dress souled and not to have the room souled, too, where a fire place or a wood stove are working.
  • device which is characterized by closing and sealing means (29) of a throat (5) of said flue (1), said closing and sealing means (29) being adapted to allow said support-control means (13) of said scraping means (8) to pass through, driving means (17) of said support-control means (13) being provided, so that said support-control means (13) can pass and slide through at least one deflection (4) of said flue (1).
  • a flue cleaning process said flue being adapted to develop according at least a first substantially horizontal path (2) and a second substantially vertical path (3), is characterized by the fact that an insertion of scraping means (8) is provided along said first path (2) of the flue, as well as through a deflection (4) of scraping means (8) along a second path (3), whereas driving means (17) in correspondence of said deflection (4) allow an operator to control the deflection of support-control means (13) of said scraping means (8), starting from a throat (5) of said flue (1).
  • Fig.1 shows a traditional shape of a fire place or, better, of its flue 1, which presents a first substantially horizontal path 2 and a second substantially vertical path 3.
  • Paths 2 and 3 are connected each to other by means of a deflection 4.
  • the external bottom end of path 2 presents a throat 5, which can have a circular, square or rectangular shape.
  • throat 5 can have a circular, square or rectangular shape.
  • hose 6 is adapted to be inserted in the paths 2,3 (Figg.9,1O), to an upper end 7 of which a brush 8 is adapted to be fixed.
  • Hose 6 represents support-control means of device according to the invention, whereas brush 8 represents scraping means of said device.
  • Hose 8 is made of a steel wire 6a, which is spiral-wounded as a pre-loaded spring, so that each spiral adhere to the next one, practically making up a hose.
  • Brush 8 is fixed to the end 7 of the hose 6 by means of a screw 9, which is adapted to allow a plurality of scraping elements 1O a rest position, where said elements 1O are overlapped each to the other in order to simplify their transportation, or an operating position, where the elements 1O are offset, each with respect to others, in order to make up a shape adapted to operate as scraping means of fuel 1, as it will explained forwards.
  • Elements 10 are made of harmonic steel stripes, so that they can be elasticly deformated during reciprocating either axial or rotating movement of hoses 6, depending on the shape of fuel 1.
  • elements 10 are made of steel stripes, having the same lenght and a starwise shape, in operating position.
  • elements 10 are made of two steel stripes, which are vertical with respect to the walls of fuel and two steel stripes, which develop according to the diagonal direction.
  • additional stripes 11 can be provided, especially in correspondence of greater side of rectangle. Said stripes 11 are welded to the end of diagonal stripes. Also additional stripes 12 can be provided, which are operating according to a vertical direction with respect to stripes 10.
  • Hose 6, to which brush 8 is connected is adapted to be joined, in correspondence of side opposite to the end 7, to other hoses 13, each one of which is made of steel spiral wounded wire 13a, likewise wires 6a of hose 6, and is provided with a threaded fitting 14.
  • Said fitting 14 is adapted to be screwed in a corresponding seat of both hose 6 and hoses 13 (Fig,9b), so that they can reach a suitable height of fuel 1 for a cleaning operation of it, starting from bottom of fuel. It is well knokn, indeed, that the strongest debris are stored on the walls in correspondence of the lower part of fuel, but it necessary to proceed with cleaning operation till a suitable height of the fuel, at least 2/3 of this height.
  • Hose 6 and hoses 13 are adapted to pass, in correspondence of deflection 4, through at least tubolar elements 16a,16b,16c of a device 17 (Figg.5,6), which represents driving means of hoses 6,13. Said device 17 allows, as it will be apparent forwards, hoses 6,13 to follow deflection 4 between path 2 and path 3.
  • Device 17 presents, for each hose 16, a support 18a,18b,18c, all said supports being able to rotate around a pivot 19.
  • Element 16c is adapted to cooperate with element 16b by means of a screw 20, wich is provided with a head 21. Screw 20 is adapted to mesh with a threaded seat of a block 23, which is integral with support 18c.
  • angular opening of support 18c can be suitably adjusted with respect to support 18b.
  • support 18a is adapted to cooperate with support 18b by means of a screw 24, which si provided with a head 26.
  • Screw 24 is adapted to mesh with a threaded seat of a block, not represented in the drawings, which is integral with support 18a.
  • angular opening of support 18a with respect to support 18b can be suitably adjusted.
  • the other end of screw 24 is adapted to rotate in the seat, which is obtained on block 22, integral with support 18b.
  • a block 28 is adapted to cooperate with element 16a (Fig.8) and is adapted to cooperate also with other blocks 28, having the same or a different axial lenght.
  • Said blocks represent a connection between support 18a of device 17 and a flange 29, which represents closing and sealing means of device according to the invention (Fig.2).
  • Blocks 28 are made of a main body 31 and of a fitting 32 (Fig.8), which is adapted to be inserted into the main body 31 of next block.
  • a last block 33 is provided with a pin 34, which is adapted to engage a corresponding hole obtained in the flange 29.
  • a threaded portion 35 of block 33 is adapted to engage an interior thread of a coupling 36 (Fig.11), in correspondence of external part of flange 29.
  • the first block 28 is fixed to element 16a of device 17 by means of a screw 37, which is adapted to be engaged by a hole 38 of next block 18, and so the other blocks 18 are connected each to other in the same way, as well as block 33, which is connected to last block 28.
  • Said blocks 28 present a plurality of axial lenghts, which are different each from others, so that their total coupling is able to satisfy the entire lenght of path 2 as long as block 33 presents its threaded portion 35 outside throat 5.
  • a ring seal 39 is applied on the internal part of flange 29, and is adapted to adhere to the external edge of throat 5.
  • Flange 29 presents, on its part which is to be placed on throat 5, a couple of squares 41 (Fig.3), which represent locking means of flange 29 on throat 5.
  • a slide 43 is pivotally connected around an axis situated on an upper end 42, connected to each square 41.
  • an elastic element 44 is applied which has to cooperate with internal wall of throat 5 of path 2.
  • Each square 41 is provided with two pins 46, which are adapted to engage two corresponding seats of flange 29.
  • a block 47 is adapted to be crossed by a screw 48 in correspondence of external part of said flange 29.
  • Screw 48 is provided with a head 49, which is adapted to engage a thread obtained on the upper part of square 41. It will be explained forwards that, by turning screw 48, square 41 leans towars external part of flange 29 and stops against walls of path 2 and locks flange 29, which can, therefore, adhere, thanks to ring seal 39, to throat 5. Thread of a tube 52 (Fig.12) is adapted to cooperate with thread of block 33, by means of coupling 36.
  • the plurality of hoses 13, connected each to the other, as it was explained earlier, is adapted to slide inside tube 52, which represents external support means oh hoses 6,13.
  • Flange 29 presents, in correspondence of internal part of throat 5 a piece of tube 53, which is screwed on a threaded sleeve 54 (Fig.4,12) welded to flange 29.
  • a bent tube 56 is screwed on sleeve 54.
  • a flexible sleeve 57 is adapted to connect the end of tube 56 with an end of a curved tube 58, which crosses tube 52 (Fig.13).
  • Said tube 52 presents, inside curved tube 58, an opening 59, in correspondence of the part opposite to the part where sleeve 57 connects tube 56 with tube 58.
  • the other end of curved tube 58 is connected with a flexible tube 61 of an aspirator not represented in the drawings.
  • Tube 53, together with tube 56, flexible sleeve and tube 58 represents aspirating means of device according to the invention.
  • Scraping means 1O of Fig.1O can be substituted with other scraping means, as shown in Fig.11 by a inflatable device 62, which is made of a substantially elastic ball, externally covered by rough material, for instance marble or glass powder integrally attached on the external surface of ball.
  • Said ball is adapted to be connected, in a way known per sè, to the end of hose 6 (Fig.9a), whereas a flexible tube, for instance a rubber one, inserted inside hose 6, is adapted to be connected, on one side, with an end 63 of ball and, one the other end, with a compressor, in a way known per sè.
  • Said compressor is not represented in the drawings.
  • Inflatable ball 62 is adapted to be inserted inside flue 1, in the same way as scraping means 8, and is, at a certain point, inflated by compressor, as long as it reach an intermediate shape represented in Fig.11b with a continuous line. If inflation goes on, ball 62 is obliged by air pressure to adhere also in correspondence of corners of fuel, as long as it reaches a shape represented in Fig. 11b with a dashed line.
  • Flue cleaning device operates as follows. After operator visually and manually controls shape of throat 5 and in which way deflection 4 of path 2 develops (Fig.1), he manually inserts hose 6 into path 2, after fixing brush 8 on its end (Figg.9,1O). Selection of brush is made, as for dimensions and shape, according to what previously evaluated by operator, by using traditional or specific tools. Instead of brush 8, the ball 62 (Figg.11a,11b) can be fixed to hose 6, which is connected to rubber tube inserted inside hose 6. Depending on lenght of path 2, one or more hoses 13 are screwed to hose 6.
  • first path 2 is substantially horizontal and second path 3 is substantially vertical, but different shapes of paths 2,3 can be present.
  • device 17 is able to adjust hoses 6,13 according the same development which the flue 1 has, in correspondence of first and second paths 2,3.
  • Brush 8, as well as ball 62 can start scraping the walls of flue 1 thanks to elements 10,11 or to rough covering of ball 62 by means of an alternative axial or rotating movement of hoses 6,13 and, therefore, of brush 8 or ball 62.
  • stripes 1O present their ends slightly bent down, as long as brush 8 is pushed topwards, whereas they present their ends bent up, as long as brush 8 is pushed bottomwards. It is apparent that scraping action exerted by steel stripes 10, as well as by brush 62, will cause debris scraped from flue walls during cleaning operation, to fall down. Number of hoses 13 connected each to others depend on the lenght of flue, which is to be cleaned.
  • Scraping action of scraping means 8,62 should interest at least 2/3 of the entire flue lenght.
  • hoses 13 are made slide within all block 28 (Fig.8), which are necessary for obtaining, starting from element 16a of device 17, a run of path 2, where, by adding a block 33, the plane of external wall of throat 5 is reached.
  • sleeve 36 and, on the other end of said sleeve, tube 52 are screwed on threaded part 35 (Fig.7) of block 33, and holes 13 are made slide inside tube 52.
  • Previously tube 56 is screwed on sleeve 54 and is, in such a way, connected to flexible tube 57 in correspondence of an end of tube 58. Opening 59 of tube 52 should be on the opposite side with respect to connection with flexible tube 57.
  • the other end of curved tube 58 is now connected with aspirator, which starts up.
  • Hoses 6,13 are manually or by means of a motor non represented in the drawings, set in alternative, axial and/or rotatory motion together with brush 8 or ball 62.
  • hoses 6,13 are interest by run of debris, which are just sucked by the action of aspirator, allowing, in such a way, internal ambience not to be involved by debris, avoiding it to be got dirty, together with the operator. All debris are collected into a container and then eliminated outside. After cleaning operation is over, hoses 6,13 are quite quite clean inside and, therefore, they can be again used for further flue cleaning operations. Just an external cleaning operation of hoses 6,13 could be suitable.
