Patent document WO 2013167692 A1 describes an ironing station comprising a steam iron and a supply unit. The iron includes a soleplate provided with a plurality of steam outlet holes and a supplementary water tank. The supply unit includes a water boiler acting like an evaporation chamber. The steam is conducted through a steam conduit from the boiler to a steam distribution chamber located in the iron in communication with the steam outlet holes of the soleplate. The boiler is at atmospheric pressure so a pump for driving the steam from the boiler to the steam distribution chamber is not necessary, and the passage of steam is controlled by a valve located in the supply unit and controlled by means of a manual push button located in the iron. In the iron there is a first pump manually operated by means of a push button obtaining water from the supplementary water tank located in the iron and conducting it directly to the steam distribution chamber, where the water evaporates upon contact with an inner surface of the soleplate, providing an additional steam function. A second pump manually operated by means of a second push button obtains water from the supplementary water tank located in the iron and conducts it to a front spray nozzle from which the water is sprayed.
The invention proposes an alternative solution to those described which allows providing several steam flow rates in a controlled manner.

The supply unit includes a water tank. A pump drives water from the water tank to the first evaporation chamber through a main water conduit, all according to the conventional art.
According to the proposal of this invention, an electrically-operated valve is intercalated in a secondary water conduit from a diversion of the main water conduit, located downstream from the pump to a second evaporation chamber which is in communication with the one or more second steam outlet holes. Therefore, and depending on the opening and closing cycles of said electrically-operated valve, the water flow rate circulating through said secondary conduit towards the second evaporation chamber can be controlled.
In one embodiment, the pump is installed in the supply unit and the electrically-operated valve and the diversion are installed in the iron. Alternatively, the pump for driving the water in the receptacle and the electrically-operated valve could be installed in the supply unit or in the iron, and the diversion could be arranged in the supply unit or between the supply unit and the iron.
In one embodiment, mentioned pump and the electrically-operated valve are operated by respective first and second solenoids the operation of which is controlled by an electronic control unit through a pulse sequence, and the iron comprises one or more switches connected to the electronic control unit and actuated by one or more manual controls that allow selecting one steam mode from three or more pre-established steam modes providing different steam flow levels.
Preferably, the one or more switches comprise a first switch activating the operation of the first solenoid operating the pump according to a single pulse sequence for providing a continuous steam flow through the one or more first steam outlet holes, and an additional multi-position switch or a plurality of additional switches activating the operation of the second solenoid controlling the opening and closing cycles of the electrically-operated valve according to multiple pulse sequences for providing different multiple additional steam flows through the one or more second steam outlet holes.
The one or more manual controls can comprise, for example, a first manual control actuating the first switch, and one or more additional manual controls actuating the additional multi-position switch or the additional switches. The first manual control and the one or more additional manual controls are preferably located in a handle of the iron. In one embodiment, the iron includes a plastic shell fixed to the soleplate, and this shell defines the handle. In this case, the first manual control is a trigger, for example, located on a front lower side of the handle and the one or more manual controls are one or more push buttons or one or more capacitive or resistive touch sensors or one or more optical sensors located on a front upper side of the handle.
In another embodiment, the pump driving the water from the receptacle is operated by a solenoid or an electric motor the operation of which is controlled by an electronic control unit through frequency variation, and the iron comprises at least one variable frequency drive connected to the electronic control unit and actuated by a manual control that allows regulating a water flow rate towards the steam evaporation chambers between a minimum flow level and a maximum flow level in a continuous or step-wise manner.
In yet another embodiment, the pump driving the water from the receptacle is operated by an electric motor the operation of which is controlled by an electronic control unit through voltage variation, and the iron comprises at least one voltage variator connected to the electronic control unit and actuated by a manual control that allows regulating a steam flow between a minimum flow level and a maximum flow level in a continuous or step-wise manner.
In any of these last two embodiments, the manual control is a sliding mechanical control or a linear touch sensor or a linear optical sensor located in a handle of the iron. The linear touch sensor can be capacitive or resistive. Optionally, the iron includes a plastic shell fixed to the soleplate, the handle is defined by the shell, and the sliding mechanical control or the linear touch sensor or the linear optical sensor is located on a front upper side of the handle.
A linear touch sensor can be capacitive or resistive, and can comprise, for example, an elongated touch-sensitive surface provided with first and second opposite ends, and calibrated such that it gives a 0% response when the first end is touched, a 100% response when the second end is touched, and a 0%-100% response when an intermediate point is touched, this 0%-100% response being proportional to the distance from the point touched to the first end.
A linear optical sensor can comprise, for example, a plurality of optical sensors adjacent to and aligned with one another, protected by a transparent cover, and calibrated such that it gives a 0% response when light is allowed to reach all the optical sensors, a 100% response when light is prevented from reaching each and every one of the optical sensors, and a 0%-100% response when light is allowed to reach only some of the optical sensors, this 0%-100% response being proportional to the number of optical sensors prevented from receiving light.
In one embodiment, the first evaporation chamber is separated from the soleplate and the second evaporation chamber is partially formed by the soleplate. Preferably, the heating means comprise a first heating element heating the soleplate and a second heating element heating the first evaporation chamber.

Detailed Description of Embodiments

First in reference to Figure 1, there is shown an ironing station according to one embodiment of the present invention, which comprises a steam iron 40 and a supply unit 50 connected to one another by a supply cord 30.
The iron 40 comprises a metal soleplate 1 and a plastic shell 23 fixed to the soleplate 1. The shell 23 defines a handle 10 by means of which the iron 40 can be gripped and handled.
The soleplate 1, schematically shown in Figure 2, has a plurality of first steam outlet holes 2 located in a first region of the soleplate 1 and a second steam outlet hole 3 located in a second region of the soleplate 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 the soleplate 1 are within the scope of the present invention.
The shell 23 of the iron 40 houses a first evaporation chamber 4 comprising a body 26 and a cover 27. The body 26 is fixed to the soleplate 1 such that there is a gap 25 between the first evaporation chamber 4 and an inner surface of the soleplate 1. There is embedded in the soleplate 1 a first electrical resistance 5 constituting a first heating element which, when activated, heats the soleplate 1 for ironing, and there is embedded in the body 26 of the first evaporation chamber 4 a second electrical resistance 6 constituting a second heating element which, when activated, heats the first evaporation chamber 4 for generating steam.
The first evaporation chamber 4 has several compartments communicated with one another and with a steam distribution chamber 11 formed in the soleplate 1, and this steam distribution chamber 11 is in turn in communication with the first steam outlet holes 2 located in the first region of the soleplate 1. A second evaporation chamber 14 closed at the top by a cover 28 is formed in the soleplate 1. This second evaporation chamber 14 is in communication with the second steam outlet hole 3 located in the second region of the soleplate 1.
The supply unit 50 includes a water tank 7. A main water conduit 8 having a first end connected to the water tank 7 and a second end connected to the first evaporation chamber 4 is included in the mentioned supply cord 30. A pump 9, which is housed in the supply unit 50, is interposed in the main water conduit 8. Therefore, the water in the water tank 7 is supplied to the first evaporation chamber 4 through the main water conduit 8 driven by the pump 9, and the steam generated in the first evaporation chamber 4 is supplied to the steam distribution chamber 11, from where it is expelled through the first steam outlet holes 2 located in the first region of the soleplate 1.
Inside the shell 23 of the iron 40 there is a secondary water conduit 12 having a first end connected to a diversion 13 of the main water conduit 8, located downstream from the pump 9, and a second end connected to the second evaporation chamber 14. An electrically-operated valve 15, for example a two-way electrically-operated valve, which is housed in the shell 23 of the iron 40, is interposed in this secondary water conduit 12. Therefore, the water in the water tank 7 is supplied to the second evaporation chamber 14 through the secondary water conduit 12, and the water flow rate circulating through said secondary water conduit, and hence the steam generated in the second evaporation chamber 14, which is expelled through the second steam outlet hole 3 located in the second region of the soleplate 1, is controlled depending on the opening and closing cycles of said electrically-operated valve 15.
In one embodiment, the pump 9 as well as the electrically-operated valve 15 are operated by respective first and second solenoids (not shown). An electronic control unit 22, which is installed, for example, in a printed circuit board 25, to which the first and second solenoids are connected, is housed in the shell 23. This electronic control unit 22 controls the operation of the first and second solenoids through a pulse sequence. The iron 40 further comprises one or more switches connected to the electronic 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 the main conduit 8 and secondary conduit 12 towards the evaporation chambers 4 and 14, respectively.
In the embodiment illustrated in Figure 1, the one or more switches of the first, second and third switches 19, 20, 21 installed in the printed circuit board 25 and the one or more manual controls comprise a first manual control 16 actuating the first switch 19, a second manual control 17 actuating the second switch 20 and a third manual control 18 actuating the third switch 21. The first manual control 16 is a trigger located on a front lower side of the handle 10 and has a first end connected to the shell 23 by means of a connecting pin 24 and a second end adjacent to the first switch 19, which is a microswitch, for example. Therefore, when the trigger is pressed it pivots around the connecting pin 24 and actuates the first switch 19. The second and third manual controls 17, 18 are push buttons located on a front upper side of the handle 10.
The first switch 19 activates the operation of the first solenoid operating the pump 9 according to a single start/stop pulse sequence P (shown in Figure 3) for providing the continuous steam flow through the one or more first steam outlet holes 2 located in the first region of the soleplate 1 according to the "normal steam" mode.
The second switch 20 activates, through the mentioned electronic control unit 22, the operation of a second solenoid controlling the opening and closing cycles of the electrically-operated valve 15 according to a first pulse sequence PI (shown in Figure 4) for providing a first additional steam flow through the one or more second steam outlet holes 3 located in the second region of the soleplate 1 according to the "extra steam" mode.
The third switch 21 activates, also through the electronic control unit 22, the operation of the mentioned second solenoid controlling the opening and closing cycles of the electrically-operated valve 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 the soleplate 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 the soleplate 1. Given that the second evaporation chamber 14 is integrated in the soleplate 1 and is heated by the same first electrical resistance 5 heating the soleplate, in order to activate the "extra steam" and "super steam" modes, the soleplate 1 must be heated to a relatively high temperature to evaporate the water in the second evaporation chamber 14.
Preferably, temperature detectors (not shown) connected to the electronic control unit 22 are arranged in the first evaporation chamber 4 and in the soleplate 1 and/or in the second evaporation chamber 14, and the electronic control unit 22 only allows operating the pump 9 and/or the electrically-operated valve 15 if the temperatures detected in the first evaporation chamber 4 and in the soleplate 1 and/or in the second evaporation chamber 14 are above a predetermined threshold for assuring evaporation of the water.
Likewise, given that the diversion 13 of the main water conduit 8 from where the secondary water conduit 12 takes water to conduct it to the second evaporation chamber 14 is located downstream from the pump 9, in order to activate the "extra steam" and "super steam" modes provided by the electrically-operated valve 15, the "normal steam" mode provided by the pump 9 must also be activated.
A main power supply unit 29 connected to a power grid through an electric power supply cable 32 is installed in the supply unit 50. Inside the shell 23 of the iron 40 there is a secondary power supply unit 31 comprising, for example, a printed circuit board 34, from which electric current is supplied to the first and second electrical resistances 5, 6 and to the electronic control unit 22 from which the first and second electric operating devices of the pump 9 and electrically-operated valve 15 are powered and controlled. The main power supply unit 29 and the secondary power supply unit 31 are connected to one another by an electrical cable 33 included in the supply cord 30.
The supply cord 30 can be connected to and disconnected from the supply unit 50 by means of a connector 36 including a fluid connector for the main water conduit 8 and an electrical connector for the electrical 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 to Figure 1 except that a second electrically-operated valve 15a has been incorporated in the main conduit 8, downstream from the mentioned diversion 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-operated valves 15 and 15a, the water flows sent to each of the evaporation chambers 4 and 14, and hence the steam flows given off, as needed for the application, will be more precisely controlled.
In Figure 6, the manual control actuating the electrically-operated valves 15 and 15a is a linear touch sensor 35 located on a front upper side of the handle 10 of the iron 40 such that a user can regulate steam flow by sliding their thumb on the hand gripping the handle 10 along the linear touch sensor 35. The linear 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 the pump 9.
