Definitions

  • the present invention relates to the general technical field of devices designed to ensure the shaping of a textile article such as a garment, by subjecting it to the combined action of a heat treatment, a mechanical ironing treatment. and steam treatment.
  • the present invention relates to an electric iron comprising a hot part consisting of a soleplate and a vaporization chamber for which the temperature is ensured by means of a heating circuit in thermal relation with a device for temperature regulation or control.
  • the present invention also relates to a method for regulating an electric steam iron.
  • Steam irons known from the prior art generally comprise a heating element in thermal relation with a vaporization chamber, for example a tubular heating element molded in the foundry of said chamber, said heating element being associated with regulation means, which are most often attached to the foundry.
  • This traditional construction has several drawbacks.
  • the setpoint temperature of the regulating means is fixed at a low value, in order to obtain a low soleplate temperature, with the aim for example of ironing delicate fabric articles, not tolerating high temperatures, the prevailing temperature in the vaporization chamber is insufficient to vaporize the water introduced into said chamber. This situation is troublesome since it does not allow the production of steam when ironing delicate items.
  • the setpoint temperature of the regulating means is fixed at a high value, in order to obtain a high soleplate temperature and preferably a high vapor flow rate, in order for example to iron resistant articles, it is known and put demonstrated by thermography that the part of the sole located under the vaporization chamber is significantly cooler than the rest of the surface of the sole, in particular during the vaporization operation. This situation is troublesome since it is generally desired that the surface of the soleplate of the iron reaches its optimum temperature at the time when the steam is emitted.
  • This embodiment has the drawback of comprising two separate heating means each associated with its own regulation means. It follows that this construction is expensive, and bulky, since there are two means of regulation and that these must be arranged in the appropriate places.
  • a steam iron comprising a hot part comprising a soleplate and a vaporization chamber, the hot part being divided into at least two thermal zones, each of which is provided with a heating element, a first zone comprising at least one surface corresponding substantially to the vaporization chamber, a second zone corresponding to at least one surface corresponding substantially to the sole portion located under the chamber, the heating element of the first zone being associated with a regulating member disposed in said zone, the heating element of the second zone being associated with a regulating member disposed in said zone, the first zone and the second zone being in thermal relation to each other, the associated heating element the first zone being provided to partially heat the second zone.
  • the heating element in the second zone prevents the formation of a cold zone in the soleplate under the vaporization chamber. Ironing is therefore more efficient.
  • This embodiment also has the drawback of comprising two separate heating means each associated with its own regulation means. This realization is therefore expensive.
  • controlling the heat transfer between the soleplate and the foundry of the vaporization chamber requires a reduction in the exchange surface between the soleplate and the foundry. , which makes sealing and mechanical resistance of the sole difficult.
  • the object of the invention is therefore to produce a steam iron which makes it possible to iron thick or resistant fabrics effectively requiring a high steam flow rate, and which makes it possible to iron delicate fabrics by producing steam without risking them. deteriorate, while presenting a simple and economical construction.
  • the invention also applies to irons comprising an integrated reservoir, such as to irons comprising a separate external reservoir.
  • an electric steam iron comprising a hot part comprising a soleplate and a vaporization chamber, the hot part of the iron being divided into two thermal zones, a first zone corresponding substantially to the chamber.
  • vaporizer being provided with first heating means
  • second zone corresponding substantially to a portion of the sole disposed under the vaporization chamber being provided with second heating means
  • the first heating means being associated with a regulating member disposed in said first zone
  • the first heating means being provided for partially heating the second zone, characterized in that the second heating means are associated with the regulating member of the first zone.
  • the iron thus obtained is of a simplified design since it comprises only one regulating member.
  • the power of the second heating means must of course be chosen so as not to damage the article to be ironed.
  • powers of the second heating means chosen so as to compensate more than the drop in temperature of the soleplate due to the vaporization of the water in the vaporization chamber this arrangement makes it possible to obtain higher soleplate temperatures when water is introduced into the vaporization chamber and thus better drying items that are difficult to iron requiring a lot of steam.
  • the present invention makes it possible to obtain, with an inexpensive construction, a control of the heating means particularly suitable for ironing the various categories of articles.
  • the second heating means are formed by a flat heating element.
  • the size of the iron is thus significantly reduced, thanks to the small thickness of the flat heating element.
  • the heating of the sole is more homogeneous, the flat heating element providing heating on a surface.
  • a control method for an electric steam iron comprising a hot part comprising a soleplate and a vaporization chamber, the hot part of the iron being divided into two thermal zones, a first zone corresponding substantially to the vaporization chamber being provided with first heating means, a second zone corresponding substantially to a portion of the sole disposed under the vaporization chamber being provided with second heating means, the first heating means being associated with a regulating member disposed in said first zone, the first heating means being provided to partially heat the second zone, characterized in that the first heating means and the second heating means are regulated by the regulating member disposed in the first zone.
  • FIG. 1 shows in a longitudinal section a partial view of an embodiment of an iron according to the invention.
  • FIG. 2a shows a schematic top view in a longitudinal section of an embodiment of an iron according to the invention.
  • FIG. 2b shows a schematic top view in a longitudinal section of a variant of an embodiment of an iron according to the invention.
  • FIG. 2c shows a schematic top view in a longitudinal section of another variant of an embodiment of an iron according to the invention.
  • FIG. 3 shows a schematic view of another embodiment of an iron according to the invention.
  • FIG. 1 An embodiment of an electric steam iron according to the invention is shown in FIG. 1.
  • the iron according to the invention comprises a hot part comprising a soleplate 1 and a vaporization chamber 2.
  • the hot part of the iron is divided into two thermal zones.
  • the first thermal zone corresponds substantially to the vaporization chamber 2, and is provided with first heating means 3.
  • the second thermal zone corresponds substantially to a portion of the sole 1 disposed under the vaporization chamber 2, and is provided with second means 4.
  • the first heating means 3 are associated with a regulating member 5 disposed in said first zone and are provided for partially heating the second zone.
  • the vaporization chamber includes a metal body 22 of good heat conductive material, attached to the sole 1, on which is attached a cover 23.
  • the body 22 is fixed in known manner to the sole 1 so as to achieve a good thermal connection between said sole and said chamber.
  • the regulating member 5 is mounted on the cover 23.
  • the heating means 4 of the second zone are associated with the regulating member 5 of the first zone.
  • This arrangement is made possible by choosing second heating means 4 of an appropriate power and advantageously less than that of the first heating means 3.
  • the regulator 5 closes the electrical supply to the first heating means 3 when the temperature of the first thermal zone, substantially corresponding to the vaporization chamber 2, decreases. This condition occurs infrequently when the iron is used dry. It suffices to adjust the power of the first and second heating means 3; 4 and the calibration of the regulating member 5 so that the temperature of the sole 1 is adapted to the tissue corresponding to a given position of the regulating member.
  • the water introduced into the vaporization chamber 2 contributes to cooling the said chamber.
  • the installation of second heating means 4 under the vaporization chamber 2 makes it possible to combat the aforementioned drop in temperature. As the second heating means 4 are supplied during the aforementioned drop in temperature, the risk of burning the ironed fabrics is limited and even avoided by choosing an appropriate power for said second heating means 4, for example from 70 to 200 W.
  • the regulating member 5 When the user wants more steam, he increases the admission of water into the vaporization chamber 2.
  • the regulating member 5 is stressed by the temperature decrease following the admission of water, and acts as expected on the power supply of the first heating means 3 associated with the vaporization chamber 2.
  • the stress on the regulating member 5 acts less expected on the second heating means 4 associated with the sole 1.
  • the second heating means 4 regulated by the member 5 are in fact more supplied with energy when water is admitted into the vaporization chamber 2. It follows that if the second heating means 4 have sufficient power, for example greater than 70 W, their power supply compensates for the drop in temperature occurring on the soleplate, following the admission of water into the vaporization chamber 2.
  • the temperature control mode p specific heating means makes it possible to obtain higher sole temperatures than during dry operation for the same adjustment of the regulating member 5, when water is admitted into the vaporization chamber 2, and all the higher that a lot of water is admitted into said room.
  • This arrangement is advantageous because when an article is difficult to iron and requires a lot of steam, the higher temperature of the sole 1 will allow said article to be better dried.
  • the power of the second heating means 4 must be chosen so as not to damage the article to be ironed. A value of 200 W makes it possible to stay within an acceptable limit.
  • the second heating means 4 are formed by a flat heating element 6, as shown in Figures 1, 2a, 2b and 2c.
  • a heating element has a lower thermal inertia than tubular or shielded heating elements. This characteristic makes it possible to simplify the regulation because the temperature peak in the second zone is reached soon after or even when the power supply is cut off by the regulating member 5.
  • the flat heating element 6 heats a surface of substantially homogeneously, if such a configuration is desired, or can be easily drawn so as to bring the calories into the area most affected by the drop in temperature.
  • This element preferably occupies a relative surface of 1/6 th to 2/5 th of the total surface of the sole.
  • several flat heating elements 6 can be connected together in series or in parallel or according to any combination of these two modes so as to produce the desired thermal map, without going beyond the ambit of the invention.
  • the first heating means 3 are formed by a tubular heating element 7, molded in the foundry forming the body 22 of the vaporization chamber 2, as shown in FIG. 1.
  • the power of this element is preferably between 1000 and 2000 W.
  • the tubular heating element 7, forming the first heating means 3 comprises two branches 8, 9 substantially parallel, connected by an elbow 10, and between which extends substantially the flat heating element 6.
  • the geometry of the flat heating element 6 is in no way limited to the rectangular shape shown in FIG. 2a, but can take other forms.
  • FIG. 2b shows a flat heating element of geometry following at least in part the shape of the branches 8, 9 of the tubular heating element 7.
  • FIG. 2c shows a flat heating element whose geometry at least partially follows the shape of the bottom of the vaporization chamber.
  • FIG. 2a shows the first heating means 3 and the second heating means 4 mounted in parallel and associated with the regulating member 5 disposed in the first thermal zone.
  • FIG. 2b also shows the first heating means 3 and the second heating means 4 mounted in parallel and associated with the regulating member 5 disposed in the first thermal zone.
  • First control means 11 make it possible to deactivate the second heating means 4. Such an arrangement is advantageous in particular for ironing very delicate textiles because it allows better control of the temperature of the sole.
  • FIG. 2c also shows the first heating means 3 and the second heating means 4 mounted in parallel and associated with the regulating member 5 disposed in the first thermal zone.
  • Second control means 12 make it possible to short-circuit the regulating member 5 for the second heating means 4.
  • An electrical connection 13 mounted between the second heating means 4 and the regulating member 5 allows the control of the second means 4 by the regulating member 5 when the second control means are not in the active position forcing the supply of the second heating means 4.
  • first control means 11 (not shown in FIG. 2c) on the electrical connection 13 or on a main electrical connection 15 connecting the second heating means 4 to a point 16 on which are connected connection 13 and second control means 12.
  • first control means 11 (not shown in FIG. 2c) on the electrical connection 13 or on a main electrical connection 15 connecting the second heating means 4 to a point 16 on which are connected connection 13 and second control means 12.
  • Either of these electrical diagrams can be used in the iron shown in FIG. 3.
  • the first heating means 3 and the second heating means 4 shown in Figures 2a and 2b are mounted in parallel.
  • the mounting of the control means 11 of the second heating means 4 must in this case be modified in order to short-circuit said means 4 instead of switching them off.
  • the first control means 11 provided for switching off the second heating means 4 and the second control means 12 provided for forcing the supply of the second heating means 4 can be controlled by the user directly or indirectly.
  • the iron shown schematically in Figure 3 has a spray button 22 intended to be actuated by the user.
  • the vaporization button 22 controls a rod 20 making it possible to open an orifice 19 provided for placing a water tank 18 in communication with the vaporization chamber 2.
  • the iron shown diagrammatically in FIG. 3 also includes an ironing selector 21 designed to be actuated by the user and cooperating with the first control means 11.
  • the selector 21 is capable of occupying a dry ironing position in which the first control means 11 deactivate the second heating means 4, and at least one steam ironing position, in which the second heating means 4 can be supplied.
  • the selector 21 is capable of occupying a high steam position, in which the spray button 22 is capable of controlling the second control means 12 forcing the supply of the second heating means 4, and a delicate steam position, in which the spray button 22 cannot control the second control means 12 for supplying the second heating means 4.
  • the first position is intended for ironing difficult textiles with steam, while the second position is intended for ironing with textile vapor delicate.
  • the selector 21 in the delicate steam position limits the travel of the spray button 22. This arrangement makes it possible on the one hand to limit the opening of the orifice 19 and thereby the quantity of water admitted into the vaporization 2, and on the other hand to prevent the actuation of the second control means 12.
  • the selector 21 in the dry ironing position blocks the rod 20, directly or by means of the vaporization key 22, to prevent water from entering the vaporization chamber 2.
  • the invention also relates to a control method for an electric steam iron, comprising a hot part comprising a soleplate 1 and a vaporization chamber 2, the hot part of the iron being divided into two thermal zones, a first zone corresponding substantially to the vaporization chamber 2 being provided with first heating means 3, a second zone corresponding substantially to a portion of the sole 1 disposed under the vaporization chamber 2 being provided with second heating means 4, the first heating means 3 being associated with a regulating member 5 disposed in said first zone, the first heating means 3 being provided for partially heating the second zone, a regulation method in which the first heating means 3 and the second heating means 4 are regulated by the regulating member 5 disposed in the first zone.
  • the invention finds its application in the technical field of electric steam irons.
