Definitions

  • the present invention relates to a steam iron.
  • Ironing can currently be performed with steam irons which can have an internal boiler or a separate boiler which may be pressurized or not.
  • said boiler besides having resistors for heating the water and thermostats with automatic or manual resetting, comprise a safety plug, a pressure switch and an electric valve together with a duct for conveying the steam to the iron.
  • Said irons allow to deliver steam upon the activation of a preset button associated with said iron, and said steam can flow out instantaneously, abundantly and with a pressurized jet.
  • the disadvantage of said known irons consists of the fact that once the water of the boiler is depleted it is necessary to suspend ironing and wait several minutes before opening the plug for access to the tank arranged inside the iron.
  • said known irons have a limited endurance which cannot be immediately restored, though they have an excellent production of steam in large amounts and under pressure upon the activation of said button.
  • the steam generator has thermostats with manual or automatic resetting as well as a duct for conveying the steam to the iron.
  • Said irons having a separate boiler constituted by an instantaneous steam generator have the advantage of having a practically unlimited steam endurance, since the tank can be refilled continuously, but other disadvantages also arise: when the pump control is activated, steam is obtained with a certain delay (after several seconds), and less pressure and less abundance of steam are obtained with respect to the previously described method.
  • a steam iron as defined in the preamble of claim 1.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known irons by providing a steam iron having a boiler which is separate from the iron itself and allows the immediate delivery of steam in large amounts and under pressure upon the activation of a control arranged on the iron.
  • Another important object is to provide a steam iron which can have practically unlimited endurance, without compelling the user to perform continuous refilling operations and assiduous checks of the water level in a boiler.
  • Another important object is to provide a steam iron which associates with the preceding characteristics that of allowing the use of a boiler with low capacity.
  • Another object is to provide a steam iron which allows an energy saving.
  • a not least object is to provide a steam iron which associates with the preceding characteristics that of being reliable and safe in use and of having modest costs.
  • steam iron is used in the following description to refer to an iron of the type having a separate steam generator connected thereto.
  • the steam iron indicated by the reference numeral 2 is provided with a plate 3 and with a button 4 for activating an electric valve 5 connected to the iron 2 by means of an adapted first duct 6.
  • the electric valve 5 allows to deliver steam by being connected, by means of a second duct 7, to a boiler 8 which is separate and remote from the iron 2 itself.
  • a first resistor 9 is externally associated with the boiler 8 and has a pressure switch 10 and thermostats 11 with manual and automatic resetting.
  • the structure as generally indicated by the numeral 1 in drawing figure 1, is furthermore constituted by at least one tank 12, which is distinct from the boiler 8 and from the iron 2 and can be refilled by means of an adapted removable plug 13; water 14 can be introduced therein by means of a third duct 15 connected to a water supply, e.g. the water mains.
  • the tank 12 is connected to the boiler 8 by means of a fourth duct 16 on which a pump 17 and a non-return and/or self-triggering valve 18 are interposed.
  • the boiler 8 is furthermore internally provided with at least one second resistor 19 which has an L-shaped configuration, with a wing 20 adjacent to a lateral wall 21 of the boiler 8; the height of said wing 20 is approximately equal to that of the lateral wall 21.
  • At least one heat transducer 22 for a thermostat 23 arranged outside the lateral wall 21 is present inside said lateral wall at a preset height.
  • the water 14 is always available by virtue of the presence of the plug 13 or of the possible third duct 15.
  • the steam iron according to the invention also allows to iron optimally without having to waste time for carrying out continuous refilling operations and for waiting while the water reaches the appropriate temperature.
  • the first resistor 9 may be omitted and its functions may be performed by the second resistor 19.
  • the means suitable for actuating the pump 17 are constituted by a sensor for detecting the weight of the boiler 8: said sensor is in turn constituted by one or more springs 24 suitable for supporting said boiler 8 and by a microswitch 25 which activates the pump 17 every time the weight of the boiler 8 drops below a set value.
  • the microswitch 25 enables the pump 17, which by reintroducing water in the boiler increases its weight until the microswitch is deactivated.
  • the steam iron generally indicated by the reference numeral 200 has a plate 300 and a button 400 for actuating an electric valve 500 which is connected to the iron 200 by means of an adapted first duct 600.
  • the electric valve 500 allows the delivery of steam and is connected, by means of a second duct 700, to a boiler 800 which is separate and remote from the iron 200.
  • the boiler 800 is constituted by a resistor 900 and has a pressure switch 100 as well as thermostats 110 with manual and automatic resetting.
  • At least one tank 120 which is distinct from the boiler 800 and from the iron 200 and can be refilled by means of an adapted removable plug 130; the water 140 can be introduced therein by means of a third duct 150 which is connected to the water mains.
  • the tank 120 is connected to the boiler 800 by means of an adapted fourth duct 160 on which a pump 170 and a non-return and/or self-triggering valve 180 are interposed.
  • the boiler 800 furthermore has at least one level switch 190 which activates the actuation of the pump 170 and the opening of the third duct 150 if provided, if the water inside the boiler 800 drops below a certain level.
  • the use of the device is therefore as follows: every time the user acts on the button 400 of the iron 200, the electric valve 500 is enabled for the introduction of steam from the boiler 800, said steam being obtained as a consequence of the introduction of the water 140 in said boiler by means of the pressure pump 170.
  • Said pump is actuated by the level switch 190 whenever necessary.
  • the water 140 is always available by virtue of the presence of the plug 130 or of the possible third duct 150.
  • the invention has achieved the intended aim and objects, a device having been obtained which allows to iron and to immediately deliver steam upon the activation of the button arranged on the iron, the steam flowing out in a large amount and under pressure.
  • the device finally allows to iron optimally, without having to waste time in continuous refilling operations and in waiting for the water to reach the appropriate temperature.
