Definitions

  • the present invention relates to the general technical field of apparatus designed to shape a textile article such as a garment, by subjecting it to the combined action of a heat treatment, a mechanical treatment and steam treatment.
  • the present invention relates to an electric iron comprising a soleplate having steam outlet holes connected to a vaporization brought to temperature via a heating circuit in thermal relationship with a device for regulating or controlling the temperature, said chamber communicating with a water tank by a orifice capable of being closed by a plug, said plug making it possible to check the admission of water from the tank into the vaporization chamber.
  • An iron with several spray positions is differentiating by the flow of water admitted into the vaporization chamber offers the advantage of allowing the user to regulate the quantity of vapor emitted, to adapt it for example to the crumpled or slightly crumpled state of the article or to the nature of the fabric to be ironed.
  • a provision presents the disadvantage of letting water flow through the holes in the soleplate when the temperature of the vaporization chamber is insufficient for spray all the water admitted into said chamber, for example during ironing a delicate item requiring low sole temperatures high, and for which the appliance thermostat has been set to a temperature low set point.
  • Such an arrangement also has the disadvantage to oblige the user to adjust according to the nature of the fabric to be ironed times the appliance thermostat and the quantity of water admitted into the spraying, to prevent drops of unvaporized water from coming out sole holes.
  • the document FR2358498 describes an iron comprising a vaporization chamber and a water tank communicating with each other at by means of a shut-off valve connected to thermostatic means which control the degree of openness.
  • a bimetallic strip acts through a bent gear on a cam support against which a shoulder of the bushel to vary the degree of opening.
  • the downside of this device is to require a referral whose effort is very offset compared to the point of action on a bushel. This offset leads to adding springs which must be properly calibrated, increase the cost of assembly and iron manufacturing and reduce reliability. Also if the bushel was extracted from the iron the balancing springs would no longer be subject to opposition and would would relax by raising the reference inadmissibly.
  • Document FR2558181 describes a valve for closing the passage between the water tank and the steam chamber of an iron in which the valve seat is movable in a bellows. But this device does not not allow for a removable bushel and is not sensitive to iron temperature.
  • the object of the present invention is to remedy the drawbacks mentioned above and to produce an iron, with extractable plug, in which the water contained in the tank is admitted into the vaporization chamber only when the temperature of said chamber is sufficient to allow the vaporization of all the water arriving in said chamber.
  • a steam iron according to the invention is shown in Figure 1.
  • the iron includes a sole 11 having holes 12 for steam outlet in communication with a vaporization chamber 14.
  • the sole 11 and the vaporization chamber 14 are in thermal relation with means of heater, not shown in the figures.
  • the vaporization chamber 14 communicates with a reservoir 15 through an orifice 16 capable of being closed off by a plug 17 arranged in a housing 22. As shown in the FIG. 1 the plug 17 closes the orifice 16.
  • the water in the tank 15 cannot flow into the vaporization chamber 14.
  • the plug 17 is removable from the housing 22 to facilitate cleaning of said plug, as well as that of the housing 22 and orifice 16.
  • the plug 17 comprises a rod 5 capable of closing the orifice 16, said rod comprising a shoulder 19 capable of resting on a support 3 secured to a bellows 4 forming at least part of a sealed conduit 31 between the reservoir 15 and the vaporization chamber 14, said support 3 being capable of being actuated by a bimetallic strip 1 mounted on a wall 20 in thermal relation with the chamber vaporization.
  • the bimetallic strip 1 is fixed on a boss 30 arranged on the wall 20.
  • the wall 20 and the boss 30 are produced made of a material that conducts heat well, such as aluminum, so that transmit the thermal image of the vaporization chamber 14 to the bimetallic strip 1.
  • the walls of the orifice 16 form a nozzle joint 7 and the rod 5 has a groove 6 provided for the flow of water when it is arranged opposite said seal 7, as shown in FIG. 2.
  • FIGS. 2 to 4 show exemplary embodiments of the conduit 31.
  • the nozzle seal 7 and the bellows 4 are two separate rooms.
  • the support 3 is integral with the bellows 4, the bellows 4 being advantageously made of silicone and overmolded on the support 3.
  • the support 3 comprises an external element 33 capable of being actuated by the bimetallic strip 1, as well as an inner element 34 on which the rod 5 can rest plug 17.
  • the inner element 34 leaves at least one passage for the flow of water inside the bellows 4 when the shoulder 19 rests on the support 3.
  • the bellows 4, the nozzle joint 7 and the support 3 are made in one piece, advantageously made of silicone.
  • the support 3 comprises a stiffening element 35 disposed at inside the bellows 4.
  • the plug 17 comprises a body 18 movably mounted on the rod 5.
  • the plug 17 includes a return spring 26 mounted between the body 18 and the rod 5.
  • the body 18 has a through recess 22 pierced with a light 23 and the rod 5 comprises a head 24, designed to slide in the recess 22, and on which is arranged a lug 25 provided for sliding in the lumen 23.
  • the body 18 disposed in the housing 22 is capable of occupying a first position in which the orifice 16 is closed by the rod 5 and a second position in which the bimetal 1 is likely to move in function of its temperature the rod 5 via the support 3.
  • Figures 5 and 6 show an iron in which the body 18 occupies a first position, called the vaporization position.
  • Figure 5 shows a iron in which the vaporization chamber 14 is at low temperature and is not not likely to vaporize the water which would be admitted in said room.
  • the bimetallic strip 1 occupies a position in which the rod 5 rests on the support 3 and obstructs the opening to the right of the nozzle gasket 7. So when the iron is in position vaporization water is not admitted into the vaporization chamber 14 when it is too cold to vaporize the water, and is not likely to drip through the holes 12.
  • Figure 6 shows an iron in which the vaporization 14 has reached the working temperature for which all the water admitted into said room is vaporized.
  • Bimetallic strip 1 occupies a position in which the rod 5 rests on the support 3 and the groove 6 is located at the right the nozzle joint 7, allowing the admission of water into the vaporization 14. So when the iron is in the vaporization position the water admitted in the vaporization chamber 14 is fully vaporized and does not drip through the holes 12.
  • the rod 5 movable relative to the body 18 follows the displacement of the support 3 actuated by the bimetallic strip 1.
  • FIG. 7 represents an iron in which the vaporization chamber 14 is at low temperature
  • FIG. 8 represents an iron in which the vaporization chamber 14 has reached the temperature of job.
  • the possible displacement of the support 3 by the bimetallic strip 1 leaves always a part 36 of the rod 5 in line with the nozzle joint 7.
  • the support 3 is held in place by the rod 5, by example by a slight tightening.
  • the support 3 rests on the bimetallic strip 1.
  • the rod 5 is held by means of stop such as the lug 25 resting on the end of the light 23, under the action return spring 26.
  • the iron comprises means 40 making it possible to maneuver the body 18 from the dry position to the spray position and vice versa, and also to extract the bushel 17.
  • the user thus has an improved device allowing you to choose between dry ironing and ironing with steam, with the added guarantee that water does not flow from the holes 12 when ironing in the spray position.
  • the steam iron thus produced has an anti-drip device, compatible with extracting the plug.
  • the section of the groove 6 increases with the distance from the free end 21 of the rod 5.
  • the higher the temperature prevailing in the vaporization 14 is high the more the water flow from the reservoir 15 is important, and the more the steam flow leaving through the holes 12 is important.
  • This arrangement is interesting because the most delicate items are ironed at low temperature and do not require a large flow of steam then than thicker and more resistant items, ironed to a higher temperature, require a large flow of steam. This provision allows you to make a steam iron with an anti-drip device whose flow rate vapor varies with the temperature of the vaporization chamber.
  • the body 18 is likely to occupy several positions in which the bimetal 1 is likely to move the rod 5 by its temperature through the support 3.
  • FIG. 10 shows an iron according to the invention in which the body 18 occupies an intermediate position between the dry position and the spray position. In a position such as this position intermediate, the temperature of the vaporization chamber 14 from which the bimetallic strip 1 moves the support 3 so as to bring the groove 6 of the rod 5 opposite the nozzle joint 7 is higher than the temperature of the vaporization chamber for which this arrangement occurs when the body occupies the vaporizing position.
  • the throat section 6 increases with the distance to the free end 21 of the rod 5, the amount of water allowed at identical temperature of the vaporization chamber is greater in the spray position than in the intermediate position. This arrangement allows a steam iron to be produced with a drip-proof device and several steam flows.
  • the invention also applies to irons comprising several heating means, for example a heating means provided for preferentially heat the sole 11, and a heating means provided for preferably heat the vaporization chamber 14.
  • the invention finds its application in the technical field of irons electric steam ironing.
