Definitions
- the present invention has as its object an ironing system. Particularly, the present invention has as its object an ironing system intended for a household application.
- Ironing systems comprising a boiler necessary for the production of water vapour and, in some cases, a tank for water containment.
- the vapour produced by the boiler is conveyed to a dispensing plate which comprises a special chamber to collect and dispense the same vapour.
- the known ironing systems further comprise a resistor associated to the plate in order to heat it according to a predetermined temperature.
- the dispensing of vapour occurs through a plurality of through-holes obtained through a bottom wall of the plate.
- the holes have a vapour inlet section facing said chamber, and an outlet section obtained on a outer surface of the bottom wall. Such outer surface defines an ironing surface.
- the thus-dispensed vapour is characterized by a high rate and a high temperature, since, before escaping, it is exposed to the high temperatures induced by the resistor.
- the plate is further provided with a thermally insulated handle to allow a user to manoeuvre the same plate during the ironing operations.
- Suitable control members are associated to the plate to allow the user to select, for example, the plate temperature and/or the dispensed amount of vapour.
- control members comprise a thermostat for the adjustment of the plate temperature, and a tap arranged upstream said chamber to adjust the vapour flow.
- boiler and tank are distinct from the plate, and are fixed.
- Systems are further known, in which tank and boiler are integrated to the plate.
- the ironing systems of the known type while they allow adjusting the plate temperature and the dispensed vapour flow, however they provide a single type of vapour, in terms of temperature, rate and humidity of the latter, as well as relative to the position and direction of vapour delivery.
- the known ironing systems ensure an extremely limited flexibility relative to the characteristics of the different fabrics to be ironed.
- the vapour dispensed by the known systems is directly determined by the temperature that is set on the thermostat of the ironing system, and therefore it is generally overheated vapour at high pressure, temperature and rate, and low humidity when the thermostat is set on the maximum temperature (about 210°C), whereas it is generally a very humid vapour (proximate to saturation) at a relatively low temperature and low pressure and rate when the thermostat is set on the minimum temperature (about 120°C).
- the known heating systems do not allow obtaining a type of vapour that is independent from the plate temperature as set on the ironing system thermostat.
- vapour which is dependent on the plate temperature, while being adapted for ironing many kinds of fabric, is however unsuitable to iron particularly delicate fabrics, such as synthetic or silk fabrics, or particularly resistant, such as cotton or linen.
- the technical task of the present invention is to propose an ironing system which is free from the cited drawback.

- the expansion chamber 24 is arranged outside the plate 4.
- the expansion chamber 24 is arranged above the plate 4.

- first "M1" and second “M2" vapour dispensing means are selectively operable to obtain the dispensing of the first and/or second vapour.
- the vapour coming from the boiler 2 is introduced in the pre-chamber 31.

- the vapour When the vapour enters the expansion chamber 24, the volume which can be taken up by the same increases, consequently the vapour undergoes an expansion. Furthermore, the expansion chamber 24 being at a relatively low temperature, the vapour is also cooled. This lowers the vapour temperature and pressure.
- the second vapour is characterized by low dispensing temperature and rate and high humidity.
- the second vapour is thus proximate to the condensation condition, due to the high humidity thereof.
- the second vapour is at a temperature ranging between 100 °C and 110 °C.
- the second vapour is then transferred to the dispensing chamber 25 through the passage port 29.
- a filter 37 occludes the passage port 29 so as to induce a further diffusion of the vapour.

- the dispensing ducts 39 have respective development axes "A" which are inclined towards the ironing surface 9, so as to dispense the vapour towards the latter ( Fig. 8 ).
- the third vapour dispensed by the dispensing ducts 39 licks the surface of a fabric to be ironed without passing through it.
- Each development axis "A” results to be inclined relative to the ironing surface 9. Such slope can advantageously be of an angle ranging between 25° and 55°, preferably between 35° and 45°.
- the dispensing ducts 39 development axes "A” are arranged preferably mutually parallel. Particularly, the development axes "A” are parallel to a middle plane “P" of the plate 4.
- the vapour flow dispensed by the dispensing ducts 39 is always directed to the direction of the plate 4 vertex 10, avoiding that the vapour flow may hit the user during the ironing operation.
- the plate 4 has recesses 40 respectively obtained on the side walls 11 of the same plate 4.
- the dispensing ducts 39 are obtained at said recesses 40.
- the dispensing ducts 39 outlet sections 39a are arranged at the recesses 40.
- each recess 40 has a surface portion 40a, for example, planar or suitably shaped, which the dispensing ducts 39 are facing.

- the collection portion 41a can be, for example, an individual one for the two side vapour chambers 41 and arranged at the tip plate, or can be double, and arranged on the plate sides, as in the illustrated example.
- a septum 43 is arranged between each collection portion 41 a and the respective dispensing portion 41 b to partially divide the said portions.
- the septum 43 is obtained in the plate 4 main body 6 starting from the bottom wall 8. However, the septum 43 does not reach the plate 4 lid 7, in this manner leaving a passage port that allows the vapour passage from the collection portion 41 a to the dispensing portion 41 b, while preventing the passage of an optional fraction of liquid water. In fact, it remains entrapped by gravity in the collection portion 41 a, until evaporation.

Description
- The present invention has as its object an ironing system. Particularly, the present invention has as its object an ironing system intended for a household application.
- Ironing systems are known, comprising a boiler necessary for the production of water vapour and, in some cases, a tank for water containment.
- The vapour produced by the boiler is conveyed to a dispensing plate which comprises a special chamber to collect and dispense the same vapour. The known ironing systems further comprise a resistor associated to the plate in order to heat it according to a predetermined temperature.
- The dispensing of vapour occurs through a plurality of through-holes obtained through a bottom wall of the plate. In detail, the holes have a vapour inlet section facing said chamber, and an outlet section obtained on a outer surface of the bottom wall. Such outer surface defines an ironing surface.
- The thus-dispensed vapour is characterized by a high rate and a high temperature, since, before escaping, it is exposed to the high temperatures induced by the resistor.
- The plate is further provided with a thermally insulated handle to allow a user to manoeuvre the same plate during the ironing operations. Suitable control members are associated to the plate to allow the user to select, for example, the plate temperature and/or the dispensed amount of vapour.
- By way of example, the control members comprise a thermostat for the adjustment of the plate temperature, and a tap arranged upstream said chamber to adjust the vapour flow.
- In the known systems, boiler and tank are distinct from the plate, and are fixed. Systems are further known, in which tank and boiler are integrated to the plate.
- Disadvantageously, the ironing systems of the known type, while they allow adjusting the plate temperature and the dispensed vapour flow, however they provide a single type of vapour, in terms of temperature, rate and humidity of the latter, as well as relative to the position and direction of vapour delivery.
- In other words, the known ironing systems ensure an extremely limited flexibility relative to the characteristics of the different fabrics to be ironed.
- In fact, the vapour dispensed by the known systems is directly determined by the temperature that is set on the thermostat of the ironing system, and therefore it is generally overheated vapour at high pressure, temperature and rate, and low humidity when the thermostat is set on the maximum temperature (about 210°C), whereas it is generally a very humid vapour (proximate to saturation) at a relatively low temperature and low pressure and rate when the thermostat is set on the minimum temperature (about 120°C).
- Accordingly, the known heating systems do not allow obtaining a type of vapour that is independent from the plate temperature as set on the ironing system thermostat.
- This type of vapour which is dependent on the plate temperature, while being adapted for ironing many kinds of fabric, is however unsuitable to iron particularly delicate fabrics, such as synthetic or silk fabrics, or particularly resistant, such as cotton or linen.
- In this context, the technical task of the present invention is to propose an ironing system which is free from the cited drawback.
- Particularly, it is the object of the present invention to propose an ironing system which is characterized by a greater flexibility relative to the type of fabric to be ironed.
-

nozzles 23 are arranged on theplate 4 in a "V"-configuration with the vertex facing theplate 4front portion 4. Correspondently, the overheatingchamber 19end portion 19a is as well essentially "V"-shaped. - In alternative embodiments, the dispensing
nozzles 23 are arranged according to different configurations, such as, for example, arched configurations. - The
nozzles 23 have respective development axes which are mutually parallel and orthogonal to the ironing surface 9. - Alternatively, the dispensing
nozzles 23 development axes have such a slope as to define an acute angle with the ironing surface 9. In other words, in this embodiment, thenozzles 23 development axis is oriented so that the overheated vapour escapes being directed towards theplate 4vertex 10. Advantageously, in this configuration, the escaped vapour interacts with a major surface of the fabric to be ironed, making the ironing operation more efficient. - The ironing system 1 further comprises second vapour dispensing means "M2" which are associated with the
plate 4 and connected to the boiler 2 to dispense a second vapour through the ironing surface 9. - The second vapour dispensing means "M2" comprise an expansion chamber connected to the boiler 2, which is adapted to reduce at least the vapour temperature and pressure before it is dispensed.
- The
expansion chamber 24 is arranged in fluidic communication with a dispensingchamber 25 to allow the passage and the dispensing of the cooled vapour in theexpansion chamber 24. - To such aim, a plurality of through-
holes 26 are obtained in theplate 4 and arranged in direct fluidic communication with the dispensingchamber 25 to allow the escape of the cooled vapour. In greater detail, theholes 26 are obtained in theplate 4bottom wall 8. - The
holes 26 have an increasing section from the dispensingchamber 25 towards the ironing surface 9.Such holes 26 have an average diameter ranging between 2 and 3,5 mm, preferably between 2,5 and 3 mm. - It shall be noticed that the
expansion chamber 24 and the dispensingchamber 25 are distinct from the describedoverheating chamber 19. Similarly, theholes 26 are distinct from the dispensingnozzles 23. - The dispensing
chamber 25 is integrally obtained in theplate 4. More precisely, the dispensingchamber 25 is defined by its owndefining walls 27 obtained in theplate 4main body 6 and by the cited lid 7. - On the contrary, the
expansion chamber 24 is arranged outside theplate 4. In greater detail, theexpansion chamber 24 is arranged above theplate 4. In still greater detail, theexpansion chamber 24 is rested to theplate 4 lid 7 by a plurality offeet 28 adapted to keep theexpansion chamber 24 lifted from the lid 7. - Advantageously, the
expansion chamber 24 being arranged outside theplate 4, the temperature thereof is below that of the rest of theplate 4. On the other hand, thefeet 28 keep theexpansion chamber 24 divided from theplate 4 lid 7, concurring to limit theexpansion chamber 24 heating. - Advantageously, the
expansion chamber 24 is overlaid to the dispensingchamber 25 so as to allow a quick transfer from theexpansion chamber 24 to the dispensingchamber 25 without the occurrence of significant changes in the characteristics of the cooled vapour. To this aim, theexpansion chamber 24 is directly connected to the dispensingchamber 25 by apassage port 29. - In greater detail, the
expansion chamber 24 comprises two mutually coupledshells 30. - The second dispensing means "M2" further comprise a pre-chamber 31 obtained inside the
plate 4.Such pre-chamber 31 is connected to the boiler 2 to receive the vapour from the latter, and is in fluidic communication with theexpansion chamber 24 in order to introduce the vapour in the latter. - As it shall be more clearly understood below, the cited pre-chamber 31 advantageously prevents that water in liquid state is introduced into the
expansion chamber 24. - The pre-chamber 31 is obtained at the
plate 4rear portion 4b. Particularly, the pre-chamber 31 is defined by theside walls 11 and therear wall 12 of theplate 4, as well as by a dividingdiaphragm 32 developing essentially parallel to theplate 4rear wall 12. - Therefore, the pre-chamber 31 is arranged in the vicinity of the
resistor 13, but is not arranged in direct contact with the latter. In other words, the pre-chamber 31 temperature is lower, relative to that of the zone which directly contacts theresistor 13. - The pre-chamber 31 comprises an
inlet coupling 33 to connect asupply tube 34 of the vapour coming from the boiler 2 and anoutlet coupling 35 to connect thesame pre-chamber 31 to theexpansion chamber 24 via asuitable connection tube 36 - As will be more clearly understood herein below, the first "M1" and second "M2" vapour dispensing means are selectively operable to obtain the dispensing of the first and/or second vapour.
- In use, when the second dispensing means "M2" are activated, the vapour coming from the boiler 2 is introduced in the pre-chamber 31. The latter, being heated at least in part by the
resistor 13, allows the vapour to keep a minimum temperature in order to avoid undesired condensations during the transfer of the same vapour from the pre-chamber 31 to theexpansion chamber 24. - Furthermore, the pre-chamber 31 allows intercepting optional water fractions in liquid state coming from the boiler 2 Such water fractions, remaining inside the pre-chamber 31, can evaporate before being brought into the
expansion chamber 24. - When the vapour enters the
expansion chamber 24, the volume which can be taken up by the same increases, consequently the vapour undergoes an expansion. Furthermore, theexpansion chamber 24 being at a relatively low temperature, the vapour is also cooled. This lowers the vapour temperature and pressure. - In this context, therefore, the second vapour is characterized by low dispensing temperature and rate and high humidity. The second vapour is thus proximate to the condensation condition, due to the high humidity thereof. Tipically, the second vapour is at a temperature ranging between 100 °C and 110 °C.
- The second vapour is then transferred to the dispensing
chamber 25 through thepassage port 29. In order to improve the expansion, in the described embodiment, afilter 37 occludes thepassage port 29 so as to induce a further diffusion of the vapour. Agasket 38 is arranged at thefilter 37 between theexpansion chamber 24 and the dispensingchamber 25. - Therefore, the vapour expanded and cooled is ejected from the dispensing
chamber 25 through theholes 26. - Advantageously, since the
holes 26 have an increasing section, the vapour is further expanded during the dispensing thereof. - The ironing system 1 further comprises third vapour dispensing means "M3" which are associated with the
plate 4 and connected to the boiler 2 to dispense a third vapour through the ironing surface 9. - The third dispensing means "M3" comprise first and second pluralities of dispensing
ducts 39 arranged along two distinct rows on eachside wall 11 of theplate 4 - In greater detail, the dispensing
ducts 39 are arranged in the proximity of theplate 4front portion 4a. - The dispensing
ducts 39 have anoutlet section 39a arranged at a higher height than the ironing surface 9. - Furthermore, in the described embodiment, the dispensing
ducts 39 have respective development axes "A" which are inclined towards the ironing surface 9, so as to dispense the vapour towards the latter (Fig. 8 ). In such a manner, the third vapour dispensed by the dispensingducts 39 licks the surface of a fabric to be ironed without passing through it. - Each development axis "A" results to be inclined relative to the ironing surface 9. Such slope can advantageously be of an angle ranging between 25° and 55°, preferably between 35° and 45°. Furthermore, the dispensing
ducts 39 development axes "A" are arranged preferably mutually parallel. Particularly, the development axes "A" are parallel to a middle plane "P" of theplate 4. - In this manner, the vapour flow dispensed by the dispensing
ducts 39 is always directed to the direction of theplate 4vertex 10, avoiding that the vapour flow may hit the user during the ironing operation. - In the described embodiment, the
plate 4 hasrecesses 40 respectively obtained on theside walls 11 of thesame plate 4. The dispensingducts 39 are obtained at said recesses 40. In greater detail, the dispensingducts 39outlet sections 39a are arranged at therecesses 40. - In still greater detail, each
recess 40 has asurface portion 40a, for example, planar or suitably shaped, which the dispensingducts 39 are facing. - With particular reference to the described embodiment, the
surface portions 40a of eachrecess 40 are arranged essentially parallel to the ironing surface 9, but they could also be arranged inclined. - The third vapour dispensing means "M3" further comprise a pair of
side vapour chambers 41 to collect the vapour produced by the boiler 2 and to dispense it through the described dispensingducts 39. - The
side vapour chambers 41 are preferably obtained in theplate 4 in the proximity of theside walls 11. Theside vapour chambers 41 are defined by arespective parting sheet 42 obtained in theplate 4main body 6. - Each
side vapour chamber 41 comprises acollection portion 41a in which the vapour coming from the boiler 2 enters, and a dispensingportion 41 b connected to thecollection portion 41 a and directly in fluidic communication with the dispensingducts 39. - Particularly, the
collection portion 41a can be, for example, an individual one for the twoside vapour chambers 41 and arranged at the tip plate, or can be double, and arranged on the plate sides, as in the illustrated example. - A
septum 43 is arranged between eachcollection portion 41 a and therespective dispensing portion 41 b to partially divide the said portions. - In greater detail, the
septum 43 is obtained in theplate 4main body 6 starting from thebottom wall 8. However, theseptum 43 does not reach theplate 4 lid 7, in this manner leaving a passage port that allows the vapour passage from thecollection portion 41 a to the dispensingportion 41 b, while preventing the passage of an optional fraction of liquid water. In fact, it remains entrapped by gravity in thecollection portion 41 a, until evaporation. - It shall be noticed that in the described embodiment, each
side vapour chamber 41 has an essentially linear inner shaping. However, in an alternative (and not shown) embodiment, theside vapour chambers 41 are so shaped as to define therein a labyrinth-shaped path to exert a overheating process on the vapour contained therein which is similar to that described in relation to theoverheating chamber 19. - Each
side vapour chamber 41 is connected to the boiler through aconnection duct 44 connected torespective connectors 45 of the sameside vapour chambers 41. - The ironing system 1 further comprises a
deflector 46 adapted to selectively direct at least the first "M1" and the second "M2" vapour dispensing means. - In the embodiment described herein, the
deflector 46 is adapted to selectively operate also the third "M3" vapour dispensing means. - In detail, the
deflector 46 is associated to theplate 4 at the above-describedbracket 17. - The
deflector 46 comprises aninlet duct 47 to which the citedhose 5, coming from the boiler 2 and carrying therewith the vapour produced, is connected. - The
deflector 46 further comprises afirst outlet duct 48 to which thesupply duct 21 is connected in order to bring vapour to theoverheating chamber 19, thereby operating the first "M1" vapour dispensing means. - The
deflector 46 further comprises asecond outlet duct 49 to which thesupply tube 34 is connected in order to bring the vapour to the pre-chamber 31 and, successively, to theexpansion chamber 24, to operate the second dispensing means "M2". - The
deflector 46 also comprises athird outlet duct 50 to which theconnection duct 44 is connected to bring vapour to theside vapour chambers 41, thereby operating the third dispensing means "M3". In other words, the operation of one of said dispensing means causes the complete deactivation of the other means. - However, in an alternative embodiment, the
deflector 46 allows partially and simultaneously operating at least two of said dispensing means. Thereby, one can obtain the combined dispensing of the first and/or second and/or third vapour. - The
deflector 46 also comprises acontrol handle 51 to select the vapour dispensing mode. - The invention achieves the intended object and accomplishes important advantages.
- In fact, the ironing system 1 according to the present invention allows a user not only to select the amount of vapour to be dispensed, but also the type thereof.
- In fact, the ironing system 1 provides to dispense the first vapour which is suitable for normal fabrics that do not require particular operating conditions or measures.
- When the user has to iron particularly resistant fabrics, he/she can operate the second dispensing means "M2" to obtain the second vapour to be dispensed in an extremely easy manner. The latter, being particularly humid, allows for an easier stretching of the resistant fabric fibers.
- On the other hand, when the user has to iron particularly delicate fabric, he/she will select the third dispensing means "M3" to obtain the third vapour which licks the fabric only at the surface thereof. Thereby, the fabric is not crossed by the vapour jet and there's no risk of damaging the latter.
- The ironing system 1 according to the present invention is generally capable of adapting the operating conditions thereof according to the type of fabric in an extremely easy manner.
