Definitions

  • the present invention relates to a steam iron.
  • Steam irons are known which are commonly used to perform ironing operations intended to remove creases and wrinkles from items of clothing and from fabrics in general.
  • Known irons are provided with a heated sole plate, which can be made to glide over the clothes placed on an ordinary ironing board; in order to improve ironing and prevent the heat released by the sole plate from spoiling certain kinds of fabric, conventional irons are provided with heated tanks suitable to generate steam, which is used to moisten the clothes to be ironed; these heated tanks, in particular, can be provided either inside the sole plate or can be external and connected to the sole plate by means of flexible hoses.
  • the steam is released through particular openings formed essentially on the sole plate, the distribution of which is particularly important for improving the performance of the iron, especially as regards the possibility to release a jet of steam capable of reaching even the most difficult points of the items of clothing, such as for example the cuffs of shirts.
  • some conventional irons are provided with openings arranged on the lower face of the iron, the one designed to be placed in contact with the item to be ironed, and with lateral openings, which allow to reach the adjacent portions of fabric without necessarily lifting the iron.
  • the outflow of steam from irons is controlled directly by the user by operating one or more control buttons for opening/closing one or more valves, which are possibly also suitable to adjust in quantitative terms the flow-rate of steam in output.
  • the aim of the present invention is to eliminate the above-mentioned drawbacks of the background art, by providing an improved steam iron that allows, other parameters being equal, to increase the flow-rate of steam at times of greater need, facilitating the task of the user in addition to improving the ironing and making it faster.
  • an object of the present invention is to provide a steam iron that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the present steam iron which comprises at least one handle that is associated in an upper region with at least one sole plate, the lower face of which is suitable to glide over fabrics, at least one heated tank, which comprises a water reservoir and means for generating steam from said water, which are connected to at least one first opening for the outflow of said steam, which is formed on said lower face and is connected to first valve means for flow management, characterized in that it comprises at least one chamber for accumulating said water and/or said steam that arrive from said heated tank, said chamber being connected to at least one second opening connected to second valve means for flow management, said accumulation chamber being suitable to store said water and/or said steam during the closure of said second valve means in order to increase the output flow-rate of the steam when said second valve means are opened.
  • the reference numeral 1 generally designates an improved steam iron.
  • the iron 1 comprises a handle, not shown in the figures because it is of a conventional type, which is associated in an upper region with a metallic and internally hollow sole plate 2, a lower face 3 of which is suitable to be kept in contact with the fabrics to be ironed, gliding thereon.
  • the profile of the lower face 3 is of the conventional type and has a pointed shape at one end and a rounded and wider shape at the opposite end; said ends form respectively the front side 4a and the rear side 4b of the iron 1.
  • a conventional electric resistor 5 which is constituted by a U-shaped rod which, during use, is suitable to be supplied with voltage in order to dissipate energy by way of the Joule effect, heating said plate.
  • the iron 1 is provided with a heated tank, not shown since it is known, which comprises a reservoir for containing water A and means for generating steam V obtained by evaporating said water.
  • the heated tank is of the external type, but applications of the present invention in which it is rigidly applied to the sole plate 2 and can move with it are not excluded.
  • the means for generating steam V are connected to at least one and preferably a plurality of first openings 6a, formed on the lower face 3, at which the steam V can be expelled from the sole plate 2.
  • the iron 1 has interposed first valve means 7a for managing the flow of the steam in output, which can be controlled from outside.
  • the iron 1 according to the invention is provided with a chamber 8 for accumulating the steam V that arrives from the tube 20, which is connected to at least one and preferably a plurality of second openings 6b connected to second valve means 7b for flow management, which can also be controlled from outside.
  • the chamber 8, during use, is suitable to accumulate internally a certain amount of steam V during the closure of the second valve means 7b; this accumulated amount is made available when said second valve means are opened in order to increase the flow-rate of steam V in output.
  • the second openings 6b are formed by a plurality of first holes 9a, which are formed through the lower face 3, and by a second hole 9b, which is arranged externally with respect to said sole plate.
  • Both the first holes 9a and the second hole 9b are arranged on the front side 4a of the iron 1; the first holes 9a, in particular, are formed at the pointed portion of the sole plate 2, while the second hole 9b is arranged above the first holes 9a and is formed by a nozzle that is orientated substantially obliquely with respect to the lower face 3 and does not intersect the sole plate 2, so as to direct the associated outflowing stream of steam V toward the portion of fabric arranged in front of said pointed portion.
  • the sole plate 2 internally comprises walls 10, which are substantially perpendicular to the lower face 3 and delimit internally a first compartment 11a and a second compartment 11b, onto which the first openings 6a and the first holes 9a open.
  • the second compartment 11b in particular, has a substantially triangular cross-section so as to reproduce the orientation of the pointed end of the sole plate 2.
  • the walls 10 that delimit the first compartment 11 a instead form a conventional labyrinth-like structure 12, which is arranged at the central portion of the sole plate 2; this structure forces the steam V to flow along a winding path through particular slots 13, formed in the walls 10, so as to facilitate the transfer of heat from the electric resistor 5 to the steam V and avoid any condensation of said steam inside the first compartment 11 a.
  • the chamber 8 which is recessed between the walls 10 of the first and second compartments 11a and 11b; in particular, it is formed in the space delimited between the blind ducts 14.
  • the chamber 8 has substantially limited dimensions and does not require condensation-preventing devices such as the structure 12; however, alternative embodiments are not excluded in which it is larger and contains a labyrinth-like structure or the like that is suitable to keep the steam V in the gaseous state.
  • first and second valve means 7a and 7b are separate and distinct.
  • the second valve means 7b in particular, comprise a first valve 15 a and a second valve 15b for adjusting the flow of steam V, which are interposed respectively between the chamber 8 and the first compartment 11a and between the chamber 8 and the second compartment 11b, while the first valve means 7a are constituted by a third valve 15c, which is independent of the others and can be associated with the boiler proximate to the means for generating the steam V, or can be arranged in the vicinity of the sole plate 2 and be rigidly coupled thereto.
  • first and second valve means 7a and 7b are instead formed by a single multifunction valve 16, which is connected to the tube 20 in order to receive said steam and send it to the first compartment 11a and/or to the chamber 8, and is connected to the chamber 8 in order to receive the steam V accumulated therein and control its delivery to the first holes 9a and/or to the second hole 9b.
  • the iron 1 is further provided with means for actuating the first and second valve means 7a and 7b, which advantageously can be of the electrical, mechanical or electromechanical type.
  • the actuation means can comprise one or more buttons arranged on the handle, which are not shown since they are of a conventional type and which, by providing one or more operating positions, are such as to control the outflow of steam V from the first openings 6a, from the first holes 9a and/or from the second hole 9b, optionally simultaneously depending on the different operating requirements.
  • the iron 1 is provided with a single tube 20, which is interposed between the means for generating the steam V and the sole plate 2 and is provided with a bifurcation 21, which in Figure 4 is formed inside the multifunction valve 16 and by means of which the tube 20 is connected both to the chamber 8 and to the first openings 6a; as an alternative, it is possible to provide two separate tubes, which are suitable to transfer the steam V separately and independently to the chamber 8 and to the first openings 6a, respectively.
  • the present invention may provide a further embodiment, shown in Figure 5, in which instead of one or more tubes 20 designed to transfer steam V there are two separate ducts 22, which are interposed between the heated tank and the sole plate 2: a first duct 22a, which is designed to transfer the steam V from the steam generation means to the first openings 6a, and a second duct 22b, which is designed to transfer to the chamber 8 part of the water A contained in the reservoir.
  • the chamber 8 is suitable to be heated by means of the electric resistor 5 in order to cause the evaporation of the water A that has reached its interior: the steam V generated by the iron 1, therefore, is partly generated inside the heated tank and sent to the first openings through the first duct 22a and partly formed directly in the chamber 8, where it is accumulated until the second valve means 7b open.
  • the improved iron according to the invention allows to make the task of the user easier and faster, since the user is not forced to dwell on prolonged operations for dispensing steam, which are instead necessary when using conventional irons.
