DESCRIPTION

Ironing system

The present invention aims at an ironing system. In particular, the present invention has as its object an ironing system intended for a domestic application (see GB-A-819577).

Ironing systems are known, comprising a boiler necessary for the production of water vapor and, in some cases, a tank for water containment.

The steam produced by the boiler is transported to a dispensing plate comprising a special chamber for collecting and dispensing the same steam. Known ironing systems further comprise a resistance associated with the plate in order to heat it according to a predetermined temperature.

The steam dispensing takes place through a plurality of through holes obtained through a bottom wall of the plate. In detail, the holes have a steam inlet section oriented to said chamber, and an outlet section obtained in an outer surface of the lower wall. Said outer surface defines an ironing surface.

The steam thus dispensed is characterized by a high speed and a high temperature, since, before escaping, it is exposed to the high temperatures induced by the resistance.

In detail, the expansion chamber causes the steam to be introduced into the plate to follow a long path that allows the steam to touch the hot walls of the plate for the time required to overheat the steam, thereby increasing the pressure and speed thereof, in addition to the temperature (see Figure 4).

The plate is additionally provided with a thermally insulated handle that allows the user to maneuver the same plate during ironing operations. There are suitable control elements associated with the plate that allow the user to select, for example, the plate temperature and / or the amount of steam dispensed.

By way of example, the control elements comprise a thermostat for adjusting the plate temperature, and a tap disposed upstream of said chamber to adjust the steam flow.

In known systems, the boiler and the tank are different from the plate, and are fixed. Additional systems are known in which the tank and the boiler are integrated with the plate.

Disadvantageously, when the fabrics are particularly strong for ironing, such as for example jeans, cotton fabrics or the like, known ironing systems do not guarantee that the suitable conditions for these fabrics are reached.

In fact, regardless of how much steam flow can be maximized, the steam dispensed is characterized by high temperature but low humidity. This feature reduces the energy that is transferred from the plate to the fabric and the ironing efficiency is also reduced.

In fact, when the fabric is particularly thick, it needs to be adequately moistened so that heat can be effectively transferred to the fabric in order to easily stretch the fibers thereof.

An example of a prior art plate is disclosed, for example, in GB 819577.

In this context, the technical task of the present invention is to propose an ironing system that is free of the aforementioned inconveniences.

In particular, it is the object of the present invention to propose an ironing system that also allows ironing particularly strong fabrics in an effective manner.

In accordance with the present invention, the technical task and the object described in this document are achieved by means of an ironing system according to claim 1.

The additional features and advantages of the present invention will be more clearly understood from the indicative, and therefore non-limiting, description of a preferred but not exclusive embodiment of an ironing system, as illustrated in the accompanying drawings, in the that:

With reference to the attached figures, the ironing system according to the present invention has been indicated in general with the number 1.

The ironing system 1 comprises a boiler 2, necessary to produce water vapor, which removes the necessary water from a tank (not shown) integrated in the boiler 2 and accessible through a plug 3.

The ironing system 1 additionally comprises an ironing plate 4 connected to the boiler 2 to dispense the produced steam.

In the described embodiment, the boiler 2 and the plate 4 are detached and are different. A special hose 5 connects the boiler 2 to the plate 4 to bring the steam produced to the latter.

However, it should be noted that the present invention finds an advantageous application also in relation to those ironing systems in which the boiler 2 is integrated with the plate 4.

The plate 4 comprises a main body 6 which is manufactured by means of, by way of example, fusion, and a cover 7 that can be placed on the main body 6.

The plate 4 further comprises a bottom wall 8 having an outer surface 8a defining an ironing surface 9 of the plate 4.

The lower wall 8 of the plate 4 has an essentially triangle-shaped isosceles design with the rounded and confluent major sides in a vertex 10 arranged in a front portion 4a of the plate 4.

A minor side is opposite in relation to the mentioned vertex 10 and is arranged in a rear portion 4b of the plate 4.

In addition, the plate 4 comprises two side walls 11 connected to the lower wall 8 and which, additionally, are convergent on the vertex 10 of the lower wall 8. A rear wall 12 is connected to the side walls 11 and the lower wall. 8 at the rear portion 4b of the plate 4.

The lower wall 8, the side walls 11 and the rear wall 12 are formed in the main body 6 of the plate 4.

The plate 4 additionally comprises a resistor 13 disposed within the plate 4. In particular, the resistor 13 is symmetrically arranged in the lower wall 8 with respect to an average plane "P" of the plate 4. Even more precisely, in the embodiment described, the resistance 13 extends over the bottom wall 8 of the plate 4 along an essentially "U" shaped path.

Suitable electrical connectors 14 allow the electrical supply of the resistor 13. In greater detail, the mentioned electrical connectors 14 are arranged at the free ends of the resistor 13 of the rear portion 4b of the plate 4.

The supply is carried to the plate 4 thanks to an electric cable 15 associated with the hose 5.

The resistor 13 heats the plate 4 according to a predetermined temperature selected by the user.

Suitable control means allow the selection and maintenance of said predetermined temperature. By way of example, the control means comprise a thermostat (not shown).

In the described embodiment, the plate 4 is provided with a handle 16 to allow the user to maneuver the plate 4, thereby allowing the ironing function.

The handle 16 is supported to the plate 4 by a support 17 rigidly connected to the same plate 4. A cover 18 made of heat-insulating material wraps the handle 16 in order to avoid burns in the user and to increase the safety conditions of the ironing system 1.

In addition, the plate 4 comprises a cover lining that is not illustrated in the attached figures.

The ironing system comprises an overheating chamber 19 connected to the boiler 2 to increase the temperature of the steam to be dispensed (see Figure 4).

More precisely, the overheating chamber 19 is obtained in the plate 4. In still more detail, the overheating chamber 19 is obtained in the main body 6 of the plate 4 and is defined in cooperation with the cover 7.

The overheating chamber 19 comprises an inlet connector 20 that allows connection to a supply conduit 21 that introduces the steam coming from the boiler 2 into the same overheating chamber 19. Specifically, the input connector 20 is obtained in the cover 7 of the plate 4.

The overheating chamber 19 comprises a plurality of dividing walls 22 that define a labyrinth-shaped path within the same overheating chamber 19. In this way, the steam introduced into the overheating chamber 19 travels a long path 25 before being dispensed.

The overheating chamber 19 is obtained in proximity to the resistor 13. In this way, during operation, the lower wall 8 of the plate 4 and the dividing walls 22 of the overheating chamber 19 are heated, and the steam, upon touching Very hot surfaces, increases its own temperature, as well as its own pressure and speed, overheating. Typically, under these conditions, the steam is at a temperature ranging from 200 ° C to 220 ° C.

Advantageously, the path of the labyrinth imposed by steam by the overheating chamber 19 makes such an overheating process quick and efficient.

The overheating chamber 19 comprises a dispensing end portion 19a. Said end portion 19a is arranged in proximity to the portion 4a of the faceplate 4.

A plurality of dispensing nozzles 23 are obtained through the bottom wall 8 of the plate 4 to allow the expulsion of the superheated steam. The dispensing nozzles 23 are in fluid communication with the overheating chamber 19. More specifically, the nozzles 23 are in fluid communication with the end portion 19a of the overheating chamber 19.

The aforementioned dispensing nozzles 23 have a diameter that is constant and ranges between 1.5 and 3 mm. Preferably, the diameter of the nozzles 23 ranges between 2 and 2.5 mm.

The dispensing nozzles 23 are arranged on the plate 4 in a "V" configuration with the vertex facing the front portion 4 of the plate 4. Correspondingly, the end portion 19a of the overheating chamber 19 is also essentially in the form of "V".

In alternative embodiments, the dispensing nozzles 23 are arranged according to different configurations, such as, for example, arcuate configurations.

The dispensing nozzles 23 have respective development axes that are mutually parallel and orthogonal to the ironing surface 9.

Alternatively, the development axes of the dispensing nozzles 23 have a slope such that it defines an acute angle with the ironing surface 9. In other words, in this embodiment, the development axis of the nozzles 23 is oriented so that the superheated steam escapes being directed towards the vertex 10 of the plate 4. Advantageously, in this configuration, the escaped steam interacts with a surface important of the fabric to be ironed, making the ironing operation more efficient.

The ironing system 1 further comprises an expansion chamber connected to the boiler 2, which is adapted to reduce at least the temperature and the pressure of the steam before it is dispensed.

The expansion chamber 24 is arranged in fluid communication with a dispensing chamber 25 to allow the passage and dispensing of the cooled steam in the expansion chamber 24.

To this end, a plurality of through holes 26 are formed in the plate 4 and arranged in direct fluid communication with the dispensing chamber 25 to allow the escape of the cooled steam. More specifically, the holes 26 are obtained in the bottom wall 8 of the plate 4.

The holes 26 have an increasing section from the dispensing chamber 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 will be noted that the expansion chamber 24 and the dispensing chamber 25 are different from the overheating chamber 19 described. Similarly, the holes 26 are different from the dispensing nozzles 23.

The dispensing chamber 25 is obtained integrally in the plate 4. More precisely, the dispensing chamber 25 is defined by its own definition walls 27 obtained in the main body 6 of the plate 4 and by the mentioned cover 7.

On the contrary, the expansion chamber 24 is arranged outside the plate 4. More specifically, the expansion chamber 24 is disposed above the plate 4. With still more concreteness, the expansion chamber 24 rests on the cover 7 of the plate 4 by means of a plurality of legs 28 adapted to keep the expansion chamber 24 raised from the cover 7 (see Figures 5 and 6).

Advantageously, the expansion chamber 24 is arranged outside the plate 4, the temperature thereof is lower than that of the rest of the plate 4. On the other hand, the legs 28 keep the expansion chamber 24 separate from the cover 7 of the plate 4, concurring to limit the heating of the expansion chamber 24.

Advantageously, the expansion chamber 24 overlaps the dispensing chamber 25 in order to allow a rapid transfer of the expansion chamber 24 to the dispensing chamber 25 without significant changes in the characteristics of the cooled vapor. For this purpose, the expansion chamber 24 is connected directly to the dispensing chamber 25 by a passage port 29.

In greater detail, the expansion chamber 24 comprises two mutually coupled shells 30.

The ironing system 1 also comprises a prechamber 31 obtained inside the plate 4. Such prechamber 31 is connected to the boiler 2 to receive steam from the latter, and is in fluid communication with the expansion chamber 24 with the In order to introduce steam into the latter.

As will be understood more clearly below, the aforementioned chamber 31 advantageously prevents the water in the liquid state from entering the expansion chamber 24.

The pre-chamber 31 is obtained in the rear portion 4b of the plate 4. In particular, the pre-chamber 31 is defined by the side walls 11 and the rear wall 12 of the plate 4, as well as by a diaphragm 32 of the developing division essentially parallel to the rear wall 12 of the plate 4.

Therefore, the previous chamber 31 is arranged in proximity to the resistor 13, but is not arranged in direct contact with the latter. In other words, the temperature of the previous chamber 31 is lower in relation to that of the zone that directly contacts the resistance 13.

The prechamber 31 comprises an inlet coupling 33 for connecting a steam supply tube 34 from the boiler 2 and an outlet coupling 35 for connecting the same prechamber 31 to the expansion chamber 24 by means of a suitable connecting tube 36 .

In use, the steam coming from the boiler 2 is introduced into the previous chamber 31. The latter, which is heated at least in part by the resistor 13, allows the steam to be kept at a minimum temperature in order to avoid condensation. desired during the transfer of the same steam from the previous chamber 31 to the expansion chamber 24.

In addition, the previous chamber 31 allows to intercept optional fractions of water - in a liquid state from the boiler 2. Such water fractions, remaining inside the previous chamber 31, can evaporate before being introduced into the expansion chamber 24.

When the steam enters the expansion chamber 24, the volume that can be taken by it increases; consequently, the steam undergoes an expansion. In addition, the expansion chamber 24 is at a relatively low temperature: the steam is also cooled. This reduces steam temperature and pressure. The vapor is then close to the condensation condition, due to its high humidity. Typically, the second steam is at a temperature ranging from 100 ° C to 110 ° C.

The expanded steam is then transferred to the dispensing chamber 25 through the passage port 29. In order to improve the expansion, in the described embodiment, a filter 37 occludes the passage port 29 so that an additional vapor diffusion is induced. A gasket 38 is disposed in the filter 37 between the expansion chamber 24 and the dispensing chamber 25.

Therefore, the expanded and cooled steam is expelled from the dispensing chamber 25 through the holes 26.

Advantageously, since the holes 26 have an increasing section, the steam expands further during dispensing.

The ironing system 1 further comprises first and second pluralities of dispensing conduits 39 arranged along two distinct rows in each side wall 11 of the plate 4 (see Figures 4 and 7).

More specifically, the dispensing conduits 39 are arranged in proximity to the front portion 4a of the plate 4.

The dispensing conduits 39 have an outlet section 39a arranged at a height higher than the ironing surface 9.

In addition, in the described embodiment, the dispensing conduits 39 have respective development "A" axes that are inclined towards the ironing surface 9, in order to dispense the steam towards the latter (see Figure 8). In this way, the steam dispensed by the dispensing ducts 39 touches the surface of the fabric to be ironed, without passing through it.

Each axis "A" of development turns out to be inclined with respect to the ironing surface. Such slope 9 can advantageously have an angle between 25 ° and 55 °, preferably between 35 ° and 45 °. Furthermore, the development axes "A" of the dispensing conduits 39 are preferably arranged in parallel with each other. In particular, the development "A" axes are parallel to a middle "P" plane of the plate 4.

In this way, the steam flow dispensed by the dispensing conduits 39 is always directed towards the direction of the vertex 10 of the plate 4, preventing the steam flow from hitting the user during the ironing operation.

In the described embodiment, the plate 4 has recesses 40 obtained respectively in the side walls 11 of the same plate 4 (see Figure 7). The dispensing conduits 39 are obtained in said recesses 40. More specifically, the outlet sections 39a of the dispensing conduits 39 are arranged in the recesses 40.

More specifically, each recess 40 has a surface portion 40a, for example, flat or with the appropriate shape, towards which the dispensing conduits 39 are oriented.

With particular reference to the described embodiment, the surface portions 40a of each recess 40 are arranged essentially parallel to the ironing surface 9, but could also be arranged inclined.

The ironing system 1 additionally comprises a pair of lateral steam chambers 41 for collecting the steam produced by the boiler 2 and for dispensing it through the dispensing ducts 39 described.

The side steam chambers 41 are obtained in the plate 4 in proximity to the side walls 11. The side steam chambers 41 are defined by a respective separation sheet 42 obtained in the main body 6 of the plate 4.

Each steam side chamber 41 comprises a collection portion 41a in which the steam from the boiler 2 enters, and a dispensing portion 41b connected to the collection portion 41a and directly in fluid communication with the dispensing conduits 39.

In particular, the collection portion 41a can be, for example, a single one for the two side steam chambers 41 and arranged on the pointed plate, or it can be double, and arranged on the sides of the plate, as in the example illustrated.

A partition 43 is arranged between each collection portion 41a and the respective dispensing portion 41b to partially divide said portions.

More specifically, the partition 43 is obtained in the main body 6 of the plate 4 from the lower wall 8. However, the partition 43 does not reach the cover 7 of the plate 4, thus leaving a louver of step that allows the passage of steam from the collection portion 41a to the dispensing portion 41b, while preventing the passage of an optional fraction of liquid water. In fact, it remains trapped by gravity in the collection portion 41a, until evaporation.

It will be noted that, in the described embodiment, each steam side chamber 41 has an internal conformation

essentially linear However, in an alternative embodiment (and not shown), the side steam chambers 41 are formed to define in them a labyrinth shaped path to exert a process of superheating in the steam contained therein, which is similar to described in relation to the overheating chamber 19.

Each side steam chamber 41 is connected to the boiler through a connection duct 44 connected to respective connectors 45 of the same side steam chambers 41.

The ironing system 1 further comprises a baffle adapted to selectively direct the steam produced from the boiler 2 at least to the dispensing ducts 39 and / or to the expansion chamber 24.

In the preferred embodiment, the deflector 46 is adapted to selectively direct the steam to the dispensing ducts 39 and / or the expansion chamber 24 and / or the superheat chamber 19.

Specifically, the deflector 46 is associated with the plate 4 in the support 17 described above.

The deflector 46 comprises an inlet conduit 47 to which the cited hose 5, coming from the boiler 2 and carrying the same steam produced there, is connected.

The baffle 46 further comprises a first outlet duct 48 to which the supply duct 21 is connected in order to bring steam to the superheat chamber 19, a second outlet duct 49 to which the supply tube 34 is connected to the in order to bring steam to the previous chamber 31 and, subsequently, to the expansion chamber 24, and a third outlet duct 50 to which the connecting duct 44 is connected in order to bring the steam to the steam side chamber 41 .

The deflector 46 also comprises a control handle 51 for selecting the steam dispensing mode.

The invention achieves the intended object and introduces important advantages.

Due to the expansion chamber 24, the steam produced from the boiler 2 expands and cools. Therefore, the steam thus obtained and dispensed through the dispensing chamber 25 has a low exit velocity and a markedly higher humidity. In fact, under these conditions, the steam is close to the condensation condition.

Therefore, the steam that is being dispensed from the holes 26 is capable of transferring heat to the fabric to be ironed in a much more efficient manner.

This feature applies particularly when the ironing fabrics are particularly strong and / or difficult to iron.

Again, in the ironing system 1 according to the present invention it is possible to select different steam dispensing modes. This makes the present ironing system 1 particularly flexible.
