Definitions

  • the present invention relates to an iron.
  • the present invention relates to an iron of the type suitable to be used in footwear and leatherware sectors.
  • the ironing operation is made by hand by qualified personnel, as it requires particular ability and attention; the application of a body heated at a high temperature may in fact damage leather irreversibly, forming burnings on the same. It is easy to understand that, especially in the presence of artefacts from precious leathers, for instance, reptilian skin, an unsatisfactory ironing intervention may cause a relevant economic loss.
  • the person that performs the ironing provides each time to humidify the part to be submitted to the ironing treatment with water or chemical substances; this avoids the formation of burnings on leather.
  • Object of this invention is to obviate the aforesaid drawback.
  • object of this invention is to realise an iron utilisable in footwear and leatherware sectors suitable to avoid the manual humidifying intervention by the operator.
  • a further object of the invention is to realise an iron as defined above, autonomously integrating means for an adequate humidifying of the artefacts, that can be activated, when necessary, in a simple, prompt and calibrated manner by the operator.
  • a not least object of the invention is to realise an iron capable of delivering constantly and quickly atomised liquid, avoiding, as a consequence, the distribution of hot fluid on the artefacts to be treated.
  • a further object of the invention is to provide users with an iron for footwear and leatherware products suitable to ensure a high level of resistance and reliability in the time, and also such as to be easily and economically realisable.
  • a fluid feeding system is associated that allows the calibrated administration of liquid to the heated tool of said iron.
  • the iron of the present invention which, being especially suitable to be used in footwear and leatherware sectors, comprises a tool, connected to a grip and handling body, made from metal and provided internally with a plurality of ducts and seats forming one or more chambers for the liquid to be atomised and an adjoining cavity for a heating body, at least one of said chambers having a partly or entirely irregular internal surface, communicating with the outside of the tool through a nozzle.
  • the iron of the present invention is basically constituted by a body 12 having an elongated shape, with a section, by way of example circular or ovoid, forming the support and the handle of the heating body, or tool 14, connected to the front end of said body 12 by means known in the art, such as screws 16.
  • Tool 14 whose shape is of a conventional type and is shown by way of example by the figures, is obtained from metal, from instance brass, by casting, and, according to the invention, is provided in its inside with a plurality of ducts and seats variously located and developed, to cause a controlled and calibrate steam delivery through an end nozzle.
  • tool 14 has, according to a preferred embodiment, a couple of tubular ducts communicating with one another which constitute as many chambers 18, 20 for the atomisation of the fluid, as well as a cavity 22 forming the seat housing a conventional heating body 24 and a hole 26 for a thermocouple 28 connected to said body 24.
  • Chambers 18, 20, preferably parallel to one another may be aligned on the same plane in the lower part of tool 14, as shown in Figure 3, or superposed, as shown in Figures 4 and 5.
  • the heating body 24 is advantageously constituted by an electric resistor or the like, fed through a conventional cable 30 which develops in body 12 forming the handle of iron 10 and comes out from the back of the same, to connect with the mains.
  • chambers 18, 20 The longitudinal development of chambers 18, 20 is such that at least one of them reaches the portion near to the front end of tool 14, in whose correspondence a small opening 32 is formed that constitutes the steam outlet nozzle. Chambers 18, 20, communicate radially between one another though one or more connecting openings 34; in the preferred embodiment, opening 34 is the only one, and is formed near the back front, opposite to nozzle 32, of chambers 18, 20.
  • the walls of said chambers 18, 20 have a rough surface 36, as shown in detail in Figure 4; the surface roughness, which is preferably formed by a continuous threading, may be alternatively obtained by broaching interventions or the like, or directly during the casting of tool 14.
  • This configuration of the walls of the chambers 18, 20 which markedly increases the contact surface between the fluid and the metal in the inside of tool 14, is particularly effective as it substantially limits the outlet from nozzle 32 of the non atomised fluid, contrasting its tendency to the known calefaction phenomenon.
  • tool 14 is heated by body 24 to a temperature higher than 100°C, which may exceed even 200°C; the drops of fluid, generally water, that are let in evaporation chambers 18, 20, would be immediately enveloped by a steam layer about the hot metal surface and would have the tendency to "skipping", without keeping in contact with said surface.
  • water droplets might come out, together with steam, with ensuing danger of deteriorating the artefact parts that are being ironed.
  • Said covering is formed, for instance, by a thin layer of inorganic salt, calcium chloride or the like, which is dissolved in the fluid and deposits spontaneously and homogeneously in the unevenness of the walls of chambers 18, 20, after a limited use of tool 14; obviously, the covering may be obtained before the use of tool 14 feeding chambers 18, 20, at suitably additivated water temperature.
  • said covering is schematised by 38 and constitutes a thin layer that covers, in a substantially homogeneous manner, the whole rough surface of atomising chambers 18, 20 of tool 14.
  • Said bush has preferably an inner diameter such as to allow the stabilisation by simple mechanical interference in the mouths of said chambers, without excluding however the possibility of realising the connection by means of glues or other systems.
  • the inner diameter of bush 42 conditions suitably the size of the tool to be inserted in chambers 18, 20, to carry out the cleaning; the tool, consequently, will have a diameter such as no to notch the tops of the rough surface of said chambers.
  • a feed system suitable to mix with air the fluid prior to its entering chambers 18, 20, through an atomising device.
  • Said atomising device indicated by 44 in Figures 5 and 7, is constituted by a tubular body 46, wherein two separate ducts 40, 50 are obtained, for delivering air and water, flowing into a mixing chamber 52.
  • Body 46 extends, before said chamber 52, into a tube 54 having a smaller diameter, whose front end 56 is fitted in and restrained, with known means, in the mouth of one of chambers 18, 20 of tool 14.
  • the front end 56 of tube 54 is fitted in chamber 18 which develops above chamber 20 in tool 12.
  • Ducts 48, 50 are connected through conventional connecting means to the feeding system, schematised as a whole by 60 in Figure 7.
  • Said system consists of a circuit fed with air, through a filter 64 and a pressure reducer 62, which is regulated as concerns both pressure and capacity.
  • the circuit develops into two distinct branches 66, 68, the first of which is connected, with the interposition of an electrovalve 70, to duct 48 of the atomising device 44.
  • the second branch 68 of the circuit enter a water-containing tank 72, exits from the same and connects, with the interposition of an electrovalve 74, to duct 50 of said atomising device 44.
  • a pressure control means such as for instance a pressure-gauge 76, allows the control of air pressure in the circuit, which is preferably comprised between 0.005 and 0.5 bar.
  • the feeding system is activated, for instance through button 12' protruding from the handle-body 12 of iron 10, the system is caused to operated thanks to the simultaneous opening of electrovalves 70, 74, respectively located near branches 66, 68, and the ensuing separate entering of a quantity of air and water in chamber 52 of the atomising device 44, wherein it mixes.
  • the pressured air-water mix passes then into tube 54 and, through its front end 56, into chamber 18 of tool 14.
  • the hole of tube 14 and the related front end 56 is suitably calibrated to realise the atomisation of the air-water mix.
  • electrovalve 74 of the water-delivering branch closes, while electrovalve 70 of the air-delivering branch remains advantageously open for a fraction of second, so as to eliminate water residues from device 44.
  • the iron of the present invention allows the substantially immediate delivery from nozzle 32 of tool 14 of steam to be locally distributed on the artefact to be ironed; no danger exists of delivering hot water drops, given the presence in tool 14 of labyrinth-like chambers 18, 20, their internal configuration and the related covering.
  • the operator who performs the ironing can work rapidly, being not obliged to humidify by hand the artefact before ironing the same with the heated tool 14.
  • the connection of iron 10 to mains 60, through the atomising device 44 allows to exactly dose minimum water quantities and to accelerate the atomisation in the inside of tool 14.
  • tool 14 may have a different number of evaporation chambers 18, 19, not necessarily having a rectilinear development, to form a more or less extended labyrinth, and the roughness of the internal walls of said chambers may be discontinuous and/or differentiated, to form more or less deep unevennesses 40.
  • the fluid feeding iron 10 may be obtained by any means, even though the connection to a system 60 of the above described type is preferred.
