Description

Technical Field

[0001] The present invention relates to the field of small household appliances, and more precisely to ironing devices. Background Art

[0002] In order to iron clothes, an iron is usually used. Due to the limitations of the use of irons (for example, an ironing board is required), portable ironing devices that do not require the aid of an ironing board and are convenient and quick to use have been developed. These devices are generally called "steam ironers" or "steam irons". When clothes are hung on a hanger, the ironing device irons by applying a hot ironing surface to the clothes, combined with the release of steam. The ironing device allows clothes to be ironed under the condition of correct use.

[0003] In practice, it has been noticed that the user does not stretch the garment sufficiently and does not press the ironing surface sufficiently against the garment, so that the action of the device is limited. As a result, the garment is not ironed as well as when the device is used correctly. Therefore, ironing devices have been proposed that, in addition to heating the garment and releasing steam, also extract the garment. However, sometimes the extraction leads to wrinkles, which is particularly undesirable. Moreover, in use, despite the extraction, the garment is not perfectly pressed against the treatment surface, which does not allow optimal ironing. Summary of the invention

[0048] According to another embodiment, the longitudinal axis P of the handle 4 is perpendicular to the outer surface 60 .

[0049] Preferably, the base 6 has a back side provided with a button allowing the device to be powered on.

[0050] Preferably, the base 6 also includes a power cord allowing it to be connected to the domestic electrical network. The cord may be detachable.

[0051] The electrical wire has a length preferably greater than 200 cm. When the user carries the device 1 to a height of about 1.5 meters above the ground, the mass of the electrical wire is preferably about 150 grams.

[0052] As mentioned above, the base 6 preferably comprises a steam generator 61 forming part of a steam circuit. The steam generator 61 is adapted to generate steam from a liquid from a reservoir 62. The steam generator 61 defines a cavity for receiving the liquid, and the steam generator 61 preferably comprises at least one shielded heating element 65 which allows the liquid from the reservoir 62 to be heated in the cavity. The steam generator 61 is preferably connected to a conduit 41 of the steam circuit, which is arranged to allow steam to flow from the steam generator 61 to the ironing head 2.

[0053] The steam generator 61 is usually made of a metal body, such as aluminum, and preferably has a mass of about 250 grams. This mass usually includes the mass of the aluminum structure, the shielding heating element 65, the electrical safety and thermal regulation elements, and the mass of the concentrator preferably included in the steam generator 61.

[0054] The reservoir 62 preferably forms part of a steam circuit, which is preferably comprised in the portable housing 10 and arranged in the base 6. According to an embodiment not shown, the reservoir 62 is removable.

[0055] according to Figure 2 In the illustrated embodiment, the reservoir 62 is disposed in the front portion of the portable housing 10 , or more specifically in the front portion of the base 6 .

[0056] The reservoir 62 preferably comprises a transparent envelope defining the outer wall of the reservoir 62, the transparent envelope being provided with a removable plug 620 allowing filling of the reservoir 62. The reservoir 62 is suitable for containing a liquid, typically water or a liquid solution diluted in water.

[0057] The reservoir 62 preferably has a capacity of about 100 mL. When empty, the reservoir preferably has a mass of about 50 grams. For example, when the reservoir 62 contains about 100 grams of water and is therefore 100% filled, it has a mass of about 150 grams.

[0058] It is also preferred that the steam circuit comprises a pump 63 arranged to cause the liquid to flow from the reservoir 62 to the steam generator 61 , and that the pump 63 is advantageously arranged in the base 6 .

[0059] The pump 63 preferably has a mass of approximately 50 grams.

[0060] The ironing head 2 is connected to the upper end of the handle 4, and the base 6 is connected to the lower end of the handle 4 opposite to the upper end. Figure 1 In the illustrated embodiment, the lower portion of the handle 4 has a flared shape, the cross section of which gradually increases as it approaches the base 6 .

[0061] The ironing head 2 comprises a front end provided with a processing surface 20 facing the fabric piece to be ironed. The ironing head 2 also comprises a rear end provided with a back surface opposite to the processing surface 20. Thus, the ironing head 2 is arranged between the processing surface 20 and the back surface along Figure 3 The longitudinal direction T shown extends.

[0062] The treatment surface 20 preferably comprises a treatment plate 200, preferably a metal treatment plate 200, for example made of aluminium.

[0063] The treatment plate 200 may be, for example, a heating plate 200 for improving ironing, as described below. Such a heating plate 200 may be heated by one or more heating elements 26 arranged in the ironing head close to the treatment surface 20.

[0064] The treatment surface 20 comprises at least one steam outlet hole 24 connected to the steam circuit and at least one suction hole 22 connected to the air suction circuit. Preferably, it comprises a plurality of steam outlet holes 24 and a plurality of suction holes 22.

[0065] The various steam outlet holes 24 and the suction holes 22 may be in the form of holes or slits. Figure 1 In the example shown, the steam outlet openings 24 are in the form of holes and the suction openings 22 are in the form of slots.

[0066] Preferably, the various steam outlet holes 24 and the suction holes 22 extend along at least one straight or curved path. Thus, if the holes have the form of slits, the slits can extend along a straight or curved path. In another conceivable case, each of a group of holes has the form of a hole and can be arranged to extend along a straight or curved path. Then, a plurality of holes of the group of holes are arranged close to each other, i.e., preferably, each hole is less than 5 mm away from the consecutive holes arranged on the path. Advantageously, the group of holes only includes holes of the same type, such as the suction holes 22, and it can be said that they extend along the suction path.

[0067] The treatment face 20 is preferably generally non-planar. For example, the treatment face 20 may have a curved profile. Preferably, the treatment face 20 has a concave profile. According to a particular embodiment, the treatment face 20 may be defined according to a plurality of planes, and its profile is not linear and has different successive segments, each segment defining an angle different from 0° and 180° with successive segments. As another example, the treatment face 20 may, for example, have a partially curved profile comprising one or more curved segments and one or more linear segments.

[0068] The processing plate 200 may be planar, as shown, or may be non-planar (eg, concave).

[0069] See also Figure 4, the distance between an outer plane P1 that is orthogonal to the longitudinal direction T and passes through the outermost point of the treatment surface 20 relative to the longitudinal direction T and an inner plane P2 that is parallel to the outer plane P1 and passes through at least one suction hole 22 of the treatment surface 20 is non-zero, preferably at least 1 mm. Preferably, the distance between the outer plane P1 and the inner plane P2 is at least 2 mm, more preferably at least 4 mm. The distance between the outer plane P1 and the inner plane P2 is preferably less than or equal to 10 mm, more preferably less than or equal to 6 mm. In other words, at least one suction hole 22 is set back relative to the plane P1. Therefore, when the treatment surface 20 approaches the fabric sheet, the at least one setback suction hole 22 will not be the first contact point between the treatment surface 20 and the fabric sheet. Therefore, the fact that at least one suction hole 22 is set back means that the treatment surface 20 is generally non-planar.

[0070] Advantageously, at least one steam outlet hole 24 is located in an outer plane P1 orthogonal to the longitudinal direction T. In other words, the steam outlet hole 24 is spaced apart from the suction hole 22 by a non-zero distance in the longitudinal direction T. Preferably, the steam outlet hole 24 is spaced apart from the suction hole 22 by a distance greater than or equal to 1 mm, more preferably greater than or equal to 2 mm, more preferably greater than or equal to 4 mm. Preferably, the steam outlet hole 24 is spaced apart from the suction hole 22 by a distance less than or equal to 10 mm, more preferably less than or equal to 6 mm.

[0071] Preferably, at least one steam outlet hole 24 is located on the treatment plate 200 .

[0072] Preferably, the suction hole 22 and the steam outlet hole 24 are spaced apart by a distance of at least 10 mm in a plane orthogonal to the longitudinal direction T. Preferably, the suction hole 22 and the steam outlet hole 24 are spaced apart by a distance of less than or equal to 50 mm in a plane orthogonal to the longitudinal direction T. It is also preferred that the suction hole 22 and the steam outlet hole 24 are spaced apart by a distance of between 15 mm and 35 mm in a plane orthogonal to the longitudinal direction T.

[0073] It should be noted that when referring to the distance between or relative to the holes, it should be understood to be between or relative to the centers of the holes.

[0074] Advantageously, at least one suction hole 22 is located at a peripheral point of the treatment surface 20. "Peripheral" means that the point is close to the edge of the treatment surface 20. Preferably, the peripheral point is spaced from the edge of the treatment surface 20 in a plane orthogonal to the longitudinal direction T by a distance of less than or equal to 10 mm, more preferably less than or equal to 7 mm, more preferably less than or equal to 5 mm. Preferably, the peripheral point is spaced from the edge of the treatment surface 20 in a plane orthogonal to the longitudinal direction T by a distance greater than or equal to 1 mm, more preferably greater than or equal to 3 mm, more preferably greater than or equal to 5 mm.

[0075] Preferably, the suction hole 22 is arranged in the upper part or the lower part of the treatment surface 20. The lower part of the treatment surface 20 is the end of the treatment surface 20 located on the side of the handle 4. The upper part of the treatment surface 20 is the end of the treatment surface 20 opposite to the lower part. In other words, when the device 1 is in its rest position, the upper part of the treatment surface 20 is higher (further from the ground) than the lower part.

[0076] In fact, it is preferred that the suction holes 22 are not arranged on the lateral part of the treatment surface. Therefore, it is preferred that the suction holes 22 are arranged in the upper part and / or the lower part of the treatment surface 20. In other words, the treatment surface 20 has no lateral suction holes, i.e. no suction holes placed laterally.

[0077] Preferably, the treatment surface 20 comprises at least two suction holes 22, which are located at two peripheral points of the treatment surface 20 opposite to each other. Advantageously, the first suction hole 22 is arranged at the upper part of the treatment surface 20, and the second suction hole 22 is arranged at the lower part of the treatment surface 20. Figure 1 In the illustrated embodiment, the treatment surface 20 includes first suction holes 22A in the form of slits arranged at the upper portion and second suction holes 22B in the form of slits arranged at the lower portion.

[0078] Preferably, the treatment surface 20 includes a plurality of suction holes 22 located at the periphery of the treatment surface 20 , and the suction holes 22 are grouped according to two peripheral areas of the treatment surface facing each other, usually the upper and lower parts of the treatment surface 20 .

[0079] according to Figure 1 In the illustrated embodiment, the suction holes 22A, 22B are arranged around the treatment plate 200. In other words, the suction holes 22 are not arranged on the treatment plate 200.

[0080] The treatment surface 20 can have different shapes, such as rectangular or triangular. According to a specific embodiment, the treatment surface 20 has a substantially rectangular shape and includes a plurality of suction holes 22 arranged along two long sides of the rectangular shape. "Long sides" refers to the two sides with the longest length among all sides of the rectangle.

[0081] According to another embodiment, the treatment face 20 has a substantially triangular shape and comprises a plurality of suction holes 22 arranged along one side of the triangle. Furthermore, it is preferred that at least one suction hole 22 is arranged at an angle opposite to the side of the triangle.

[0082] According to this embodiment, advantageously, when the device 1 is in its rest position, the treatment face 20 is arranged so that one side of the triangle (called the main side) is parallel to the ground. Preferably, the triangular shape is an isosceles triangle and the base of the isosceles triangle (the side having a length different from the two sides of equal length) is the main side. It is also advantageous that a plurality of suction holes 22 are arranged along the main side. It is further preferred that at least one suction hole 22 is arranged at an angle relative to the main side.

[0083] The structure of the treatment surface 20 shown allows better pressing of the fabric piece against the treatment surface 20 during ironing. In fact, the fabric piece is sucked by the suction holes 22 and, since these holes are arranged "backwards" as described above, the fabric piece is pressed against the treatment surface 20 more than according to the embodiment in which the treatment surface 20 is flat.

[0084] Advantageously, the suction aperture 22 comprises a filter.

[0085] Advantageously, the secondary steam generator 25 is arranged in the ironing head 2. The secondary steam generator 25 forms part of the steam circuit. The secondary steam generator 25 is preferably connected to the conduit 41. In fact, the secondary steam generator 25 allows the liquid from the steam generator 61 (called "primary steam generator") to evaporate again, which has flowed in the conduit 41. In fact, when the steam flows in the conduit 41, the steam can be cooled to the extent that a part of the steam condenses. Therefore, the steam condensate flows to the secondary steam generator 25. The secondary steam generator 25 preferably allows evaporation of these condensates so that no liquid is discharged via the steam outlet hole 24. It is particularly advantageous to avoid liquid discharge via the steam outlet hole 24, because this will wet the processed fabric piece and not allow it to be well ironed. In order to evaporate the condensate, the secondary steam generator 25 preferably includes at least one PTC thermistor type heating element 26 or a shielded heating element. The secondary steam generator 25 can also be called an "evaporator" because it allows the steam generated by the steam generator 61 to be heated again.

[0086] Preferably, the shielded heating element 26 of the secondary steam generator 25 is in thermal contact with the treatment surface 20. Thus, the treatment surface 20, preferably more precisely the heating plate 200, can be heated by one or more heating elements 26 of the secondary steam generator 25, which allows more effective ironing when the treatment surface 20 is arranged facing the fabric piece.

[0087] According to an embodiment not shown, the silicone component is placed between the heating element 26 of the secondary steam generator 25 and the treatment surface 20 so that the temperature of the treatment surface 20 does not exceed a certain temperature threshold, typically 150°C.

[0088] The secondary steam generator 25 is generally made of a metal body, such as aluminum.

[0089] The secondary steam generator 25 also preferably includes electrical safety and thermal regulation elements.

[0090] Thus, the assembly including the treatment surface 20 and the secondary steam generator 25 preferably has a mass of approximately 100 grams.

[0091] The ironing head 2 comprises a motor 23 forming part of the air suction circuit. Preferably, the motor 23 is arranged inside the ironing head 2 in the axial extension of the treatment surface 20. The motor 23 is arranged along Figure 3 A longitudinal axis M is shown extending.

[0092] according to Figure 3 The ironing head 2 has an elongated shape extending transversely to the handle 4, preferably forming an angle α of about 65° with respect to the longitudinal axis P of the handle. Preferably, the handle 4 extends along an axis passing through at least a part of the motor 23. The axes P and M advantageously intersect.

[0093] The motor 23 is adapted to drive the fan 21 to rotate. The fan 21 constituting a part of the air suction circuit allows air to be sucked from the air suction holes 22.

[0094] The assembly comprising the motor 23 and the fan 21 preferably has a mass of approximately 300 grams.

[0095] Preferably, the air suction circuit is configured to allow more than 10m 3 / h and less than 60m 3 The air suction flow rate is preferably greater than 20 m / h. 3 / h and less than 50m 3 / h air suction flow rate.

[0096] The operation of the device will now be described.

[0097] When the user wishes to use the device, he fills the reservoir 62 with liquid (preferably water) and then starts the device 1 by pressing a button to power it on. It is assumed that the device has previously been connected to the household power grid by electrical wires. The heating elements of the primary steam generator 61 and the secondary steam generator 25 are then powered to reach their operating temperature, which is advantageously regulated by a thermostat.

[0098] When the user wishes to use the device in the vertical ironing position, he orients the treatment surface 20 vertically towards the piece of fabric to be ironed and then presses the control device 8 (preferably a button here), which has the effect of running the pump 63 and allowing liquid to flow from the reservoir 62 to the primary steam generator 61.

[0099] The steam generated in the primary steam generator 61 then escapes through the duct 4 towards a possible secondary steam generator 25 and then through the steam outlet openings 24. The steam is then diffused onto the fabric piece, which in combination with the heating and drying action of the treatment plate 200 allows it to be ironed.

[0100] At the same time, the control device 8 can be designed to activate air suction combined with steam discharge. For example, pressing the control device 8 can allow the motor 23 to be powered, and the motor 23 starts running. Therefore, the fan 21 is driven to rotate and air is sucked in through the suction holes 22. Suction in particular allows the fabric piece to be pressed against the treatment surface 20. The structure of the treatment surface 20 also allows the fabric piece to be pressed against the treatment surface 20. Therefore, steam discharge combined with suction allows optimized ironing. In addition, air suction also allows to promote the drying of the fabric piece part that has just been subjected to steam. It has been found that this particular method allows to maintain a longer ironing effect over time after treating the fabric piece.

[0101] According to another embodiment, the control device 8 allows the user to control the puffing in a manner independent of the steam emission control. Thus, the user can control the steam emission alone or in combination with the puffing.

[0102] During treatment, the user may move the device 1 in a vertical direction, for example from top to bottom, to treat all or part of a piece of fabric.

[0103] The device 1 may also be used occasionally in a horizontal ironing position, for example to iron a piece of fabric lying horizontally on a table, by positioning the treatment surface 20 horizontally above the piece of fabric.

[0104] The invention is not limited to the embodiments described and shown in the drawings. Modifications are still possible without departing from the general teaching, in particular in the composition of the various technical features, or by replacement by technical equivalents.
