- The foregoing and other features and advantages will be better understood from the following merely illustrative and non-limiting detailed description of several embodiments in reference to the attached drawings, in which:
-
Figure 1 is a schematic side view of an ironing station according to one embodiment of the present invention; -
Figure 2 is a schematic top view of a soleplate of a steam iron that is part of the ironing station ofFigure 1 ; -
Figure 3 is a voltage/time diagram of a pulse sequence according to which a pump included in the ironing station works; -
Figure 4 and 5 are voltage/time diagrams of first and second pulse sequences, respectively, according to which a second electrically-operated valve included in the ironing station can selectively work; and -
Figure 6 is a schematic side view of an ironing station according to another embodiment of the present invention. - First in reference to
Figure 1 , there is shown an ironing station according to one embodiment of the present invention, which comprises asteam iron 40 and asupply unit 50 connected to one another by asupply cord 30. - The
iron 40 comprises ametal soleplate 1 and aplastic shell 23 fixed to thesoleplate 1. Theshell 23 defines ahandle 10 by means of which theiron 40 can be gripped and handled. - The
soleplate 1, schematically shown inFigure 2 , has a plurality of first steam outlet holes 2 located in a first region of thesoleplate 1 and a secondsteam outlet hole 3 located in a second region of thesoleplate 1. Variations in the number and arrangement of the first steam outlet holes and second steam outlet holes 2, 3 and in the location and extent of the first and second regions of thesoleplate 1 are within the scope of the present invention. - The
shell 23 of theiron 40 houses afirst evaporation chamber 4 comprising abody 26 and acover 27. Thebody 26 is fixed to thesoleplate 1 such that there is agap 25 between thefirst evaporation chamber 4 and an inner surface of thesoleplate 1. There is embedded in the soleplate 1 a firstelectrical resistance 5 constituting a first heating element which, when activated, heats thesoleplate 1 for ironing, and there is embedded in thebody 26 of the first evaporation chamber 4 a secondelectrical resistance 6 constituting a second heating element which, when activated, heats thefirst evaporation chamber 4 for generating steam. - The
first evaporation chamber 4 has several compartments communicated with one another and with asteam distribution chamber 11 formed in thesoleplate 1, and thissteam distribution chamber 11 is in turn in communication with the first steam outlet holes 2 located in the first region of thesoleplate 1. Asecond evaporation chamber 14 closed at the top by acover 28 is formed in thesoleplate 1. Thissecond evaporation chamber 14 is in communication with the secondsteam outlet hole 3 located in the second region of thesoleplate 1. - The
supply unit 50 includes awater tank 7. Amain water conduit 8 having a first end connected to thewater tank 7 and a second end connected to thefirst evaporation chamber 4 is included in the mentionedsupply cord 30. Apump 9, which is housed in thesupply unit 50, is interposed in themain water conduit 8. Therefore, the water in thewater tank 7 is supplied to thefirst evaporation chamber 4 through themain water conduit 8 driven by thepump 9, and the steam generated in thefirst evaporation chamber 4 is supplied to thesteam distribution chamber 11, from where it is expelled through the first steam outlet holes 2 located in the first region of thesoleplate 1. - Inside the
shell 23 of theiron 40 there is asecondary water conduit 12 having a first end connected to adiversion 13 of themain water conduit 8, located downstream from thepump 9, and a second end connected to thesecond evaporation chamber 14. An electrically-operatedvalve 15, for example a two-way electrically-operated valve, which is housed in theshell 23 of theiron 40, is interposed in thissecondary water conduit 12. Therefore, the water in thewater tank 7 is supplied to thesecond evaporation chamber 14 through thesecondary water conduit 12, and the water flow rate circulating through said secondary water conduit, and hence the steam generated in thesecond evaporation chamber 14, which is expelled through the secondsteam outlet hole 3 located in the second region of thesoleplate 1, is controlled depending on the opening and closing cycles of said electrically-operatedvalve 15. - In one embodiment, the
pump 9 as well as the electrically-operatedvalve 15 are operated by respective first and second solenoids (not shown). Anelectronic control unit 22, which is installed, for example, in a printedcircuit board 25, to which the first and second solenoids are connected, is housed in theshell 23. Thiselectronic control unit 22 controls the operation of the first and second solenoids through a pulse sequence. Theiron 40 further comprises one or more switches connected to theelectronic control unit 22 and the switches are actuated by one or more manual controls whereby it is possible to select one steam mode from three steam modes providing different steam flow levels, namely: a "normal steam" mode providing a continuous steam flow, an "extra steam" mode providing an additional steam flow, and a "super steam" mode providing an enhanced additional steam flow, all this depending on the water flows supplied through themain conduit 8 andsecondary conduit 12 towards theevaporation chambers - In the embodiment illustrated in
Figure 1 , the one or more switches of the first, second andthird switches circuit board 25 and the one or more manual controls comprise a firstmanual control 16 actuating thefirst switch 19, a secondmanual control 17 actuating thesecond switch 20 and a thirdmanual control 18 actuating thethird switch 21. The firstmanual control 16 is a trigger located on a front lower side of thehandle 10 and has a first end connected to theshell 23 by means of a connectingpin 24 and a second end adjacent to thefirst switch 19, which is a microswitch, for example. Therefore, when the trigger is pressed it pivots around the connectingpin 24 and actuates thefirst switch 19. The second and third manual controls 17, 18 are push buttons located on a front upper side of thehandle 10. - The
first switch 19 activates the operation of the first solenoid operating thepump 9 according to a single start/stop pulse sequence P (shown inFigure 3 ) for providing the continuous steam flow through the one or more first steam outlet holes 2 located in the first region of thesoleplate 1 according to the "normal steam" mode. - The
second switch 20 activates, through the mentionedelectronic control unit 22, the operation of a second solenoid controlling the opening and closing cycles of the electrically-operatedvalve 15 according to a first pulse sequence P1 (shown inFigure 4 ) for providing a first additional steam flow through the one or more second steam outlet holes 3 located in the second region of thesoleplate 1 according to the "extra steam" mode. - The
third switch 21 activates, also through theelectronic control unit 22, the operation of the mentioned second solenoid controlling the opening and closing cycles of the electrically-operatedvalve 15, but in this case according to a second pulse sequence P2 for providing a second additional steam flow that is greater than the first one through the one or more second steam outlet holes 3 located in the second region of thesoleplate 1 according to the "super steam" mode. - This embodiment allows for multiple variants. For example, the operation of the mentioned second solenoid controlling the opening and closing cycles of the electrically-operated
valve 15 can be activated by means of more than two additional switches or by means of an additional multi-position switch, which allows selecting one pulse sequence from more than two pre-established pulse sequences for providing more than two different additional steam flows through the one or more second steam outlet holes 3. Accordingly, the manual controls can include more than two additional manual controls for actuating the more than two additional switches, or a single additional manual control for actuating the additional multi-position switch. The one or more additional manual controls can be, for example, one or more push buttons, or one or more capacitive or resistive touch sensors, or one or more optical sensors. - As is conventional, the iron includes a thermostat-based temperature control device, or an NTC with its TRIAC- or relay-type associated power electronics or the like (not shown) actuated by a manual control (not shown) that allows regulating the temperature of the first
electrical resistance 5 heating thesoleplate 1. Given that thesecond evaporation chamber 14 is integrated in thesoleplate 1 and is heated by the same firstelectrical resistance 5 heating the soleplate, in order to activate the "extra steam" and "super steam" modes, thesoleplate 1 must be heated to a relatively high temperature to evaporate the water in thesecond evaporation chamber 14. - Preferably, temperature detectors (not shown) connected to the
electronic control unit 22 are arranged in thefirst evaporation chamber 4 and in thesoleplate 1 and/or in thesecond evaporation chamber 14, and theelectronic control unit 22 only allows operating thepump 9 and/or the electrically-operatedvalve 15 if the temperatures detected in thefirst evaporation chamber 4 and in thesoleplate 1 and/or in thesecond evaporation chamber 14 are above a predetermined threshold for assuring evaporation of the water. - Likewise, given that the
diversion 13 of themain water conduit 8 from where thesecondary water conduit 12 takes water to conduct it to thesecond evaporation chamber 14 is located downstream from thepump 9, in order to activate the "extra steam" and "super steam" modes provided by the electrically-operatedvalve 15, the "normal steam" mode provided by thepump 9 must also be activated. - A main
power supply unit 29 connected to a power grid through an electricpower supply cable 32 is installed in thesupply unit 50. Inside theshell 23 of theiron 40 there is a secondarypower supply unit 31 comprising, for example, a printedcircuit board 34, from which electric current is supplied to the first and secondelectrical resistances electronic control unit 22 from which the first and second electric operating devices of thepump 9 and electrically-operatedvalve 15 are powered and controlled. The mainpower supply unit 29 and the secondarypower supply unit 31 are connected to one another by anelectrical cable 33 included in thesupply cord 30. - The
supply cord 30 can be connected to and disconnected from thesupply unit 50 by means of aconnector 36 including a fluid connector for themain water conduit 8 and an electrical connector for theelectrical cable 33. -
Figure 6 shows an ironing station according to another embodiment of the present invention, which is similar to the one described above in relation toFigure 1 except that a second electrically-operatedvalve 15a has been incorporated in themain conduit 8, downstream from the mentioneddiversion 13 and for the purpose of providing an additional control of the water flow rate provided towards the first evaporation chamber. By means of this embodiment and depending on the opening and closing cycles of the electrically-operatedvalves evaporation chambers - In
Figure 6 , the manual control actuating the electrically-operatedvalves linear touch sensor 35 located on a front upper side of thehandle 10 of theiron 40 such that a user can regulate steam flow by sliding their thumb on the hand gripping thehandle 10 along thelinear touch sensor 35. Thelinear touch sensor 35 can be capacitive or resistive, but alternatively this control can also be a sliding mechanical control or a linear optical sensor. Furthermore, said manual control also acts on the variable frequency drive feeding thepump 9.
