    FIELD OF THE INVENTION
    The present invention relates to a steam ironing device suitable for ironing different types of fabrics. HISTORIC
    It is well known that a temperature for ironing, that is, the temperature at which an item being ironed is heated during the ironing process, must be chosen depending on the type of fabric of the item in order to obtain ideal results when ironing. For example, if the item is made of cotton, the temperature for ironing it can be relatively high, for example, approximately 175 ° C, while when the item to be ironed is made of polyamide or elastane, the the temperature to pass it must be much lower, for example, approximately 95 ° C, to avoid burning the item.
    The approximate ironing temperature, which should be used to iron a particular type of fabric for optimal ironing results, can be found in a variety of publications, including encyclopedia or instruction websites, user manuals for the ironing device. ironing with manufacturers' recommendations and patent publications. An additional authorized category of publications referring to international standardization standards, including, for example, ISO 3758 ('Fabrics - Instruction label code using symbols') of the International Organization for European Standardization and Standard EN 60311 (' Electric irons for domestic or similar use - methods for measuring performance ') originated from the European Committee for Standardization and approved by the European Committee for Electrotechnical Standardization. The ISO standard provided instruction labels for maximum ironing temperatures. The ISO Standard instruction label is indicated by one, two or three dots located on an ironing symbol. The European Standard takes into account the recommendations of the ISO Standard, but for best results when ironing, temperatures have been adjusted as shown in the following table:

    Consequently, although the exact temperatures may differ, it is generally assumed that an item is best ironed at a temperature that corresponds to the type of fabric in which it was made.
    According to this criterion, practically all current domestic irons (steam) are equipped with an aluminum base that can be heated, whose temperature is manually adjustable in a range of 70 to 210 ° C. To properly iron a particular fabric with such an iron, the user is expected to be aware of its thermal properties, or at least the type of fabric and / or recommended temperature settings, and to adjust the temperature of the aluminum base iron, according to this, before it starts ironing the respective fabric. Disregarding the recommended setting adjustment of the aluminum base temperature can cause unsatisfactory results when ironing, and even thermal damage to the ironed material if the temperature of the aluminum base inadvertently exceeds the maximum recommended temperature.
    The need to be aware of the thermal properties of a fabric and to adjust the temperature of the iron base of the iron, by changing one type of fabric to another (if the current setting is not adequate), is considered laborious and not favorable to the user. However, there appears to be a need for inherently different thermal properties of different fabrics.
    In an attempt to provide a more user-friendly iron, WO 2008/034693-A1 discloses a steam iron including a heatable iron base, a heating device to heat the iron base and an integrated automatic temperature control device, which is coupled to the heating device and designed to maintain the temperature for ironing the iron base exclusively in a pre-configuration in a fixed way, manually not changeable, temperature range for constant ironing 180 ° C to 190 ° C when operating the steam iron. WO'693 shows that all fabrics, in particular clothing and fabrics for home use, which do not include special industrial fabrics, can be ironed in said temperature range with 'very good' results when ironing. Supposedly, 'good' results when ironing are still obtained when items are ironed dry, that is, without the application of steam. WO'693 also recommends that fabrics, which according to EN 60311 have a maximum ironing temperature of 160 ° C (ie, two-point fabrics, see Table 1), can be ironed with steam using 'good' results in the said temperature range of 180 to 190 ° C.
    Tests carried out by the applicant of the present application cannot confirm the claims made by WO'693. It is presumed that delicate items are checked with a temperature indication to iron clothes from one point on their instruction labels for a reason. For example, attempts to iron one-point acrylic clothes using an iron at an aluminum base temperature of 165 ° C (really still safely outside the range claimed by WO'693), both with and without the use of steam, resulted in damage to the clothes in the form of permanent hardening of the fabric. In fact, tests have shown that even two-point items, such as polyester or wool clothing, are preferably not ironed at this temperature, as this can cause irreversible damage during normal ironing. In the case of a partially polyester garment (65% polyester, 35% cotton) ironing resulted in hardening of the fabric, while in the case of a 100% polyester garment, the softness and adhesion of the aluminum-based material was observed the iron. In another test, when ironing a woolen clothes dry at an aluminum base temperature of 165 ° C there was a noticeable discoloration. It is assumed that the thermal damage observed in these tests would be more evident if the temperature of the aluminum base was raised to a range recommended by WO'693 from 180 to 190 ° C.
    The degree of damage caused by an iron with an overheated aluminum base can, presumably, be mitigated by continuously moving the iron through clothes at an exceptionally fast rate, thus avoiding mainly the transfer of large amounts of heat from the base of aluminum to a single area of the fabric. However, such ironing is somewhat tiring and would require the average / average user to adjust their ironing habits. In a practical way, the tests described above, in this way, seem to verify the strong belief that a temperature for ironing is better chosen depending on the type of fabric of the item, thus, avoiding damage and obtaining satisfactory results when ironing.
    Since the problem addressed by WO'693 has not yet been solved, it is an objective of the present invention to provide an ironing device with which different types of fabrics can be ironed with satisfactory results when ironing, without requiring that the user adapts any settings when ironing by changing one fabric to another. SUMMARY OF THE INVENTION
    The invention is defined by claim 1. The dependent claims define advantageous embodiments. One aspect of the present invention relates to a steam ironing device. The ironing device includes an iron, including an aluminum base that is provided with at least one steam outlet, and an aluminum base heating means configured to heat the aluminum base. The ironing device further includes a steam generator comprising a heatable steam generating chamber which is fluidly connectable or connected to at least one steam outlet in the aluminum base. The ironing device also includes a control means which is operably connected to the aluminum base heating means and the steam generator, and configured to control an aluminum base temperature and steam settings of the steam ironing device. The control medium is configured to (it has the aluminum base heating medium) to heat the aluminum base to a temperature not adjustable by the user in the range of 105 to 145 ° C, and to (it has the steam generator) to release steam in a temperature not adjustable by the user in the range of 100 to 150'C and in a variation of average time steam of at least 50 grams / minute.
    The ironing device according to the present invention is based on research that, surprisingly and contrary to popular belief, has revealed that satisfactory results by ironing various types of fabrics at a universal temperature and steam settings can be achieved. Thus, the ironing device, in accordance with the present invention, does not provide user control controls that allow the user to adjust the temperature of the aluminum base and / or selected steam settings, among which the temperature and the rate at that the steam is released from the steam outlet openings on the aluminum base, to certain desired values other than zero. Instead, the control medium is configured exclusively for automated / non-adjustable user control that combines a relatively low aluminum base temperature, not manually adjustable with a modest vapor temperature and a relatively high minimum vapor range.
    The lower limit of the temperature range of the aluminum base, 105 ° C, is chosen high enough to avoid condensation of vapor, since it is emitted from at least one steam outlet opening in the aluminum base. Condensation is preferably avoided, as it may result in temporary moist stains due to drops and / or splashing of water. The upper limit, 145 ° C, is selected from the perspective of fabric safety and is sufficiently low to prevent burns or other damage to delicate items. In particular, for items with a one-point temperature indication, the safety of the upper temperature limit, which can escape the temperature range of a point (see Table 1), is guaranteed by the constant emission of a substantial vapor flow of the aluminum base. The temperature range of (125 ± 20) ° C can be reduced to (125 ± 10) ° C to improve the above effects and make the iron work more resistant and safer in non-standard ironing conditions (for example , involving thick, cold and thermally conductive items that can temporarily lower the temperature of the aluminum base to approximately 100 ° C). The temperature of 125 ° C in the center of these ranges has been found to provide good results, as will be discussed in more detail below.
    The steam used by the steam ironing device has a dual function of heating and humidifying an item to be ironed. Studies have shown that steam is more effective when it heats an item than a hot aluminum base due to the involvement of mass transfer and latent heat. However, if the steam temperature is chosen too high, very little steam can condense on the material, both to transfer enough heat and to properly moisten the item's fabric. A good balance can be achieved by using steam at temperatures below 150 ° C, for example, temperatures of approximately 100 to 150 ° C. The steam pressure, both inside the steam generator and in the release of the aluminum base, is preferably maintained at an absolute pressure below approximately six bar.
    The rate of steam calculated over time has been found to consistently provide acceptable results when ironing is approximately 50 grams / minute. Higher steam rates may - at least for some fabrics - improve ironing results, but time-calculated steam rates above 70 grams / minute do not appear to significantly improve any additional ironing results.
    The term 'calculated by time', as used in relation to the ironing rate of the ironing device, serves to include both the achievements that characterize continuous or constant steam emission and the achievements that characterize non-continuous or time-varying steam emission through the scope of the invention. Typically, for the first category, the vapor rate calculated over time can be approximately the same according to the instantaneous vapor rate. To discount small variations in the instantaneous vapor rate, the vapor rate calculated over time can be calculated over a relatively long period of steam emission, for example, a period of sixty seconds. For realizations in the second category, the vapor rate calculated over time cannot be approximately the same as the instantaneous vapor rate at a certain point in time. A steam iron can, for example, be configured to intermittently release steam at peak rates well above 70 grams / minute, while its time-calculated steam rate may still fall in the range of 50 to 70 grams / minute. For example, an iron in the system can be configured to release steam according to a periodic steam release pattern composed of repeated 20-second cycles, each cycle including 5 (consecutive) steam releases at a rate of 240 grams / minute, followed by 15 seconds during which the steam is released. Such a periodic vapor release pattern presents the vapor rate calculated over time to ((5 * 240) + (15 * 0) / (5 + 15) =) 60 grams / minute. Consequently, for the purpose of determining the rate of steam calculated over the time of an iron, it can measure the rate of steam over a period of sixty seconds, unless the iron releases steam at a rate that varies with time based on in a periodic vapor release pattern, in the latter case, the vapor rate calculated over time can be calculated by measuring the vapor rate over the duration of a period of the periodic vapor release pattern in question.
    It is noted that the specified minimum steam rate is applicable only when the ironing device is used effectively for ironing. In other words: the control means can include a sensor to register at least one of the movement of the iron, a position / orientation of the iron and contact between the aluminum base and a fabric being ironed, and additionally be configured to adapt, mainly to interrupt or reduce, the release of steam below the minimum vapor rate when a signal from the sensor reflects that the aluminum base is not in contact with a fabric being ironed, that is, it is not being used effectively to iron clothes. A motion sensor can, for example, detect whether an iron is being suspended, a position / orientation sensor can detect whether the iron is in its resting position and a contact sensor can detect whether the aluminum base is out of contact with a fabric being ironed, all of these situations can occur during an ironing job, for example, during a period of exchanging an item ironed for another item to be ironed.
    Without wishing to be restricted to theories, the following explains the fact that a combination of a relatively low aluminum base temperature and steam released at a modest temperature and a relatively high vapor rate seems to provide good results when ironing.
    During the process of ironing, a fabric is typically heated to loosen intermolecular bonds between the long chain polymer molecules in the fibers of the fabric. In its loose condition, the weight of the iron can force the fibers into a wrinkle-free state. When the stress on the fibers is properly removed the wrinkle-free state of the fabric will be largely maintained after cooling. The removal of stress in the fibers of the fabric is significantly increased by heating the fabric above its glass transition temperature. For many fabrics (mostly natural), such as cotton, wool and linen, the glass transition temperature depends on a moisture content. The dependence is such that an increase in the moisture content or the humidity reduces to the transition temperature. Thus, a higher moisture content can improve the degree of relaxation from stress, and consequently the result of ironing at the same temperature. To ensure that a fabric can be properly moistened, the ironing temperature of the iron (which results from both the aluminum base temperature and the steam settings) should not be chosen too high; after all, the higher the temperature for ironing, the higher the temperature to which the fabric being ironed is heated, and the lower the rate of vapor condensation on the fabric.
    Once an item has been ironed, wrinkles that have been ironed may partially return as the fibers in the fabric cool. It is assumed that the return of wrinkles is due to the retraction of the fibers during the cooling period that naturally follows a heating period during the ironing process. In general, fibers heated to a lower temperature are observed to undergo less thermal expansion than fibers heated to a higher temperature. As a result, the degree of shrinkage to which the anterior fibers are subsequently subjected under cooling is also lower. Thus, heating an item to a lower temperature can contribute to reducing the appearance of wrinkles.
    The steam and temperatures of the aluminum base and the steam rate of the steam ironing device according to the present invention have been selected empirically. The respective values are considered to achieve a balance between the factors described above and, thus, allow sufficient humidification and consequent relaxation of the fabric fibers without causing their unnecessary heating and associated thermal expansion.
    As mentioned, the steam ironing device according to the present invention features an aluminum base and steam temperatures that are not adjustable by the user. In addition, in some embodiments of the ironing device, other steam settings, for example, the steam rate, may also not be adjustable by the user.
    Aluminum base temperature not adjustable by the user and steam settings allow the construction of a simpler ironing device, which is advantageous both from the point of view of ease of use and economy in manufacturing, since there is no need special user controls. It should be noted, however, that the term not adjustable by the user should not be interpreted as necessarily meaning that the parameter in question is fixed, constant or invariant. Rather, the word should be interpreted as meaning that the ironing device does not include a user control that allows a user to (intentionally) adjust the respective parameter when performing an action that extends beyond the natural operation of an iron. pass that (already) is adjusted to the temperature of the aluminum base and the desired steam characteristics. Such a natural operation may, for example, include ironing, ironing of clothes on a garment, ironing of the clothes, ironing the iron on its rest and releasing the iron. Consequently, a temperature of the aluminum base that is not adjustable by the user can, for example, be variable by the respective (automatic) control means depending on a signal from a hand or wrist sensor that registers when the iron is being held by a user, such that the temperature of the aluminum base is reduced or otherwise adjusted when the sensor signal reflects that the iron has not been held for a significant period of time, for example, fifteen minutes or half an hour. Thus, as mentioned above, a vapor rate not adjustable by the user can be varied by the respective control means (automatic) depending on a signal from a motion sensor, position / orientation or contact, such that the vapor release is interrupted or reduced when the signal from the sensor reflects that the iron is in its resting position, suspended in the air or lowered into an item to be ironed at the beginning of an interruption in the ironing process. It is understood, however, that in some embodiments of the ironing device, at least one of the temperature of the aluminum base and the rate of steam settings can be fixed and invariant - that is, it cannot be changed either by a user or by through a control means - to override the automated control functionality and to simplify the construction of the device while observing manufacturing costs.
    For comparison, it is noted here that WO 2006/000958 discloses a steam iron in which the temperature for ironing is primarily controlled by the temperature of the steam that is released from the iron. In the iron, the thermostatically controlled heating medium keeps the aluminum base at a predetermined temperature not set by the user, for example, at 110 ° C, while a temperature of the steam to be released from the iron is adjustable by the user through the input means, such as a rotatable disk or the like. Before ironing a particular item, the user must check the setting of the input medium, and adjust the input medium if the temperature setting is not representative of the temperature for the required ironing. Thus, although the steam iron, according to WO'958, features a control medium configured to heat the aluminum base to a temperature not adjustable by the user, the steam temperature must be adjusted, still, by a based on the number of items. Furthermore, WO'958 does not provide anything in particular about the steam rate of the steam iron. Thus, the steam iron of WO'958 does not solve the above mentioned problem addressed and solved by the present invention.
    These and other features and advantages of the invention will be understood more fully from the detailed description of certain embodiments of the invention, with the accompanying drawings, which are for illustration and not to limit the invention. BRIEF DESCRIPTION OF THE DRAWINGS

    Fig. 1 schematically illustrates an exemplary steam ironing device 1 according to the present invention. The steam ironing device 1, which is designed as a system iron, can include an iron 10 and a base unit 40 accommodating a steam generator 50.
    The iron 10 - that is, the portion of the ironing device 1 that can be manipulated - can include the handle 12 and an aluminum base that can be heated 18 with a plurality of steam outlet openings 20. The handle 12 can be arranged on an upper side of the iron 10 and be configured to allow a user to take the iron and move the aluminum base 18 provided on the lower side of it over an item to be ironed. The steam outlet openings 20 in the aluminum base 18 can be in fluid communication with an integrated steam chamber 16, which can be supplied with steam via the flexible combined steam hose / connection cable 14. For the purpose of heating the aluminum base 20, the heating medium of the aluminum base 22 can be
    provided. Such aluminum base heating means 22 can preferably comprise at least one flat resistant heating element arranged on a surface of the aluminum base 20, however alternative embodiments of the aluminum base heating means 22 are also possible. Such an alternative embodiment may, for example, include a conventional tubular heating element, which is arranged within the aluminum base (aluminum), or a CTP (Positive Temperature Coefficient) based on the heater in good thermal communication with the base aluminum.
    The term 'flat resistant heating element' refers to heating elements that are deposited as a thin layer on a surface by means of printing or another suitable technique, and which, under the influence of an electric current, is capable of generating heat. An example of such a heating element is a layer of synthetic resin, in which electrically conductive particles are integrated. In the event that a flat resistant heating element is arranged on a surface comprising an electrically conductive material, such as metal, it may be necessary that an electrically insulating layer is disposed between the surface and the heating element to prevent a short circuit.
    The heating means of the aluminum base 22 can be operably connected to the first control means 24, which can be in the form of a thermostat. In the event that the aluminum-based heating medium includes a CTP-based heater, a thermostat feature can be dispensed with. The first control means 24 can be configured to heat the aluminum base 18 to a temperature not adjustable by the user in the range of 105 to 145 ° C during use. In a preferred embodiment, the target temperature in this range, for which the first control means 24 is configured to heat the aluminum base 18, can be set, for example, at 125 ° C, as this allows for more construction simple and, therefore, the most economical of the first control medium 24.
    The base unit 40 can house a refillable water reservoir 44 to hold water, a steam generator or boiler 50 to generate and supply steam, a water channel 46 that fluidly interconnects the water reservoir 44 and a steam generation chamber 51 of the steam generator 50, and a pump 48, arranged in the water channel 46 and configured to force the flow of water from the water reservoir 44 in the steam generation chamber 51.
    For the purpose of heating the water contained in the steam generating chamber 51, the steam generator may comprise the heating means of the steam generator 52. Like the heating means of the aluminum base 22, the heating means of the steam generator steam 52 may preferably include at least one flat resistant heating element, but it is also possible that the heating means of the steam generator 52 is designed in another way, for example, as a conventional tubular heating element or a heater based on CTP that is thermally coupled to the steam generation chamber. The steam generating chamber 51 can be connected to the steam chamber 16 of the iron 10 by means of a steam hose / thermally insulated combined connection cable 14. The steam generator 50 may also include a controllable steam valve electrically 54 by means of which the steam generating chamber 51 is connectable to the steam hose 14 and the steam chamber 16.
    The pump 48, the steam valve 54 and the heating means of the steam generator 52 can be controlled by the second control means 56. In this way, this second control means 56 can be configured to control the steam settings of the ironing device 1, for example, the vapor rate, and the temperature and pressure of the vapor. Control medium 56, which may include a simple integrated circuit (CI), can control the steam settings autonomously, typically according to the preprogrammed vaporization instructions that can define a particular vaporization cycle / pattern. In some embodiments of the steam iron 1, the second control means 56 may include one or more sensors, for example, position / orientation, motion and contact sensors capable of detecting a condition for which the instruction on Preprogrammed vaporization provides an adjustment of steam settings. The second control means 56 may, for example, include an orientation sensor (disposed on the iron 10, not shown) which is capable of detecting a vertical orientation of the steam iron 10, while the second control means can still , be configured such that, by detecting a vertical orientation of the steam iron 10, the steam rate of the ironing device 1 is reduced and vice versa. The ironing device 1 can be connected to the mains by means of a connecting cable 42, through which all electrical components of the ironing device can be supplied with electricity, possibly by means of a suitable transformer.
    The construction of the ironing device 1 can be largely of a conventional design. From the perspective of a user as well as a construction, this can be mainly the lack of temperature of the aluminum base and manually operated steam controls that configure the construction of the ironing device 1, except for the irons ( conventional). Although Fig. 1 describes the realization of the exemplary ironing device 1, according to the present invention, as a 'steam iron' (having a water reservoir 44 and a steam generator 50 on the of the iron 10), it is contemplated that the ironing device can alternatively be implemented as a 'steam iron' (having a water reservoir and a steam generator incorporated in the iron body, the which should be moved in a fabric during the ironing process).
    Now that the construction of the ironing device according to the present invention has been described in some detail, attention must be paid to its operation and performance.
    From a user perspective, the operation of the ironing device 1 is extremely simple, in particular, compared to the operation of an iron in the conventional steam system. With such an iron from the conventional steam system, a user is required to check the settings of the iron inlet before starting ironing to see if they reflect the temperature of the aluminum base. and the proper steam settings for the item to be ironed. To be sure of the desired settings, he will need to refer to them, for example, on the instruction label or in the iron user manual. In case the selected settings do not correspond to the desired settings, the user will need to adjust the settings of the input medium. You may need to repeat these steps for each item to be ironed, which is obviously more labor intensive. On the other hand, the ironing device 1, according to the present invention, cannot include any aluminum base temperature or user adjustable steam settings.
    The preconfigured settings are suitable for ironing different types of fabric safely, including virtually all household fabrics, with satisfactory results when ironing.
    As an indication of these results of ironing and the performance of the ironing device, according to the present invention, Fig. 2 illustrates the results of ironing obtained from a test, in which the fabric samples with different temperatures (maximum ) recommended for ironing were ironed with a prototype of both an iron of the system according to the present invention and an iron of the conventional system with high quality reference. The tissue sample includes (see the graph in Fig. 2 from left to right):
    a T-shirt with a combination of 40% polyester and 60% cotton with a 1-point instruction label (ie, low temperature setting);
    a silk suit, having a 2-point instruction label (ie, medium temperature setting); jeans, made of 100% thick cotton, having a 3-point label (ie high temperature setting), and
    a linen tablecloth, with a maximum temperature instruction label.
    During the test, the system's iron, according to the present invention, was configured with a constant aluminum base temperature of approximately 125 ° C and a vapor rate calculated over time in the range of 100 to 140 grams / minute ; the steam was released from the aluminum base at a temperature in the range of 100 to 110 ° C. Consequently, all tissue samples ironed with the iron prototype system were ironed in the same conditions, regardless of their nature. On the other hand, tissue samples ironed with the reference system's iron were ironed at an aluminum base temperature according to their instruction label (usually in the range of 115 to 145 ° C; see. Table 1) , and at a time-calculated vapor rate of approximately 100 to 140 grams / minute. It is observed that the vapor rate calculated by the selected time is relatively large compared to the minimum vapor rate calculated by the time of 50 grams / minute declared above. This was done simply to help reduce ironing time; the research showed that the high rate of steam itself does not significantly influence the results of ironing.
    The results of ironing were evaluated four hours after ironing and categorized on a scale designed for this purpose by SLG Prüf- und Zertif izierungs GmbH, with ranges from 1 to 5 and are strictly divided as follows:

    As can be concluded in Fig. 2, the iron in the system according to the present invention produces results that are better than the iron in the reference system for fabrics that have a recommended low or medium temperature setting, while the results for fabrics with high temperatures recommended for ironing are comparable. On average, the iron of the system according to the present invention thus has a better result.
    Figs. 3A and 3B show test results obtained from two additional ironing tests performed on a 100% cotton shirt, that is, a fabric with a recommended high temperature setting. For the test, the results of which are reflected in Fig. 3A, the cotton shirt was ironed with a prototype of both a steam iron according to the present invention and a conventional steam iron. During the test, both steam irons were configured with a vapor rate calculated over time of just over 50 grams / minute; the temperature of the aluminum base of the prototype was approximately 125 ° C, while that of the reference iron was approximately 175 ° C. For the comparative test, the results of which are shown in Fig. 3B, the cotton shirt was ironed with a prototype of both a steam iron according to the present invention and a conventional steam iron, with high quality reference. Both steam irons in the steam system were configured with the vapor rate calculated over time in the range of 100 to 140 grams / minute, and an aluminum base temperature of approximately 125 ° C and 175 ° C, respectively. The test results were evaluated four hours after ironing, and rated on a scale designed for this purpose by the American Association of Textile Chemists and Colorists (AATCC). Unlike the SLG scoring system described above, the AATCC scoring system employs softness models, to which a sample of ironed fabric can be compared and a sample of ironed fabric can be compared to assess the result of ironing. On the AATCC scale, which ranges from 0 to 5, points 2.5 and above represent satisfactory results of ironing. As can be seen in Figs. 3A and 3B, the ironing device prototypes according to the present invention score better than their respective conventional counterparts.
    Based on the above, it can be concluded that the ironing device according to the present invention has a competitive performance and, in general, better than conventional irons that are used according to its instructions for use .
