Description
Technical Field
The present invention relates to a steam iron, and more particularly to a steam iron equipped with a water droplet holding means.
Background
A steam iron comprises, in a known manner, a soleplate defining a steam distribution circuit and comprising an ironing plate equipped with an ironing surface and steam apertures opening into the ironing surface.
One problem that steam irons often have is related to the large number of water droplets being expelled through the steam vents at start-up or upon restart.
Document DE102004032361 discloses a steam iron comprising a steam distribution circuit which is equipped with a retaining device configured for retaining water droplets entrained by a flow of steam flowing along the steam distribution circuit and for evaporating the retained water droplets.
The retaining means comprise, in particular, an outer body defining a cyclonic chamber, a steam inlet opening into a lower portion of the cyclonic chamber and through which a steam flow enters into the cyclonic chamber, and a central duct provided at the centre of the cyclonic chamber and equipped with an upper steam outlet through which the steam flow exits from the cyclonic chamber.
Document GB330870 also discloses a steam iron comprising a steam distribution circuit equipped with retaining means configured for retaining water droplets entrained by a flow of steam flowing along the steam distribution circuit and for evaporating said retained water droplets.
The holding device comprises a conduit comprising a tubular peripheral wall closed at both ends by two side plates, one of which comprises an inlet opening and the other of which comprises an outlet opening.
Although such a holding means ensures that a large part of the water droplets entrained by the steam flow flowing in the steam distribution circuit is held and evaporated, a considerable amount of water droplets still reach the steam vents when such a steam iron is activated.
Disclosure of Invention
The present invention aims to overcome these disadvantages.
The technical problem on which the present invention is based therefore consists in providing a steam iron which satisfactorily limits the amount of water in liquid form which reaches the steam vents, in particular when the steam iron is started.
The present invention therefore relates to a steam iron comprising a steam distribution circuit in which a steam flow is intended to flow, and retaining means arranged along the steam distribution circuit, the retaining means being configured for retaining water droplets entrained by the steam flow and optionally for evaporating the retained water droplets, the retaining means comprising:
-a duct comprising a tubular peripheral wall having a longitudinal axis, said tubular peripheral wall comprising a lower inlet opening through which the steam flow enters the duct and an upper outlet opening through which the steam flow is discharged from the duct,
-a central body arranged at the centre of the catheter, and
-a plurality of connecting elements extending through the catheter, said plurality of connecting elements connecting together the tubular peripheral wall and the central body, said connecting elements each extending from the tubular peripheral wall up to the central body, said connecting elements and said central body covering, in a projection plane perpendicular to the longitudinal axis of the catheter, at least 60%, and preferably at least 90%, of the passage section of the catheter.
This configuration of the retaining means, and more specifically of the retaining member, forms a barrier that prevents the steam flow from carrying water droplets on a direct path arranged axially with respect to the duct, and thus ensures an effective separation of the water droplets from the water vapor, and thus a retention of a large number of water droplets entrained by the steam flow by the retaining means. Thus, at start-up of the steam iron according to the invention, only a small proportion of the liquid water reaches the steam vents of the steam iron.
The steam iron may also have one or more of the following features, which may be separate or combined.
According to an embodiment of the invention, the holding member is detachable.
According to an embodiment of the invention, the steam iron comprises an ironing plate comprising a substantially flat ironing surface, the longitudinal axis of the conduit extending perpendicular to the plane of the ironing surface.
This feature allows to have a steam flow which, when the iron is placed on its ironing board, flows vertically in the duct from bottom to top. Thus, when water droplets flow in the conduit, the water droplets carried by the steam flow are stopped by gravity and more effectively stopped by the connecting element.
According to an embodiment of the invention, the steam iron comprises a soleplate and the holding means comprises a support portion provided on said soleplate and on said soleplate said holding means is mounted, said holding means and said support portion defining an evaporation chamber, said evaporation chamber being provided upstream of said connecting element with respect to the flow direction of said steam flow, and said evaporation chamber preferably being below the connecting element when the steam iron is placed horizontally on its soleplate, so that water droplets separated from the steam flow by the connecting element fall by gravity into the evaporation chamber.
According to an embodiment of the invention, the holding means comprises a steam inlet opening into the evaporation chamber, and the steam flow opens into the evaporation chamber through the steam inlet.
According to an embodiment of the invention, the support portion comprises a bottom wall and a side wall extending from the bottom wall and on which the holding member is mounted. The steam inlet is arranged, for example, in the side wall.
According to an embodiment of the invention, the side wall of the support portion and the tubular peripheral wall of the duct are coaxial.
According to an embodiment of the invention, the steam inlet is defined in part by a tubular peripheral wall of the duct.
According to an embodiment of the invention, the steam iron comprises a cover portion at least partially defining the steam distribution circuit and covering the holding part.
According to an embodiment of the invention, the base plate comprises a covering part.
According to an embodiment of the invention, the soleplate comprises an ironing surface and at least one steam hole opening into the ironing surface.
According to an embodiment of the invention, the cover portion and the holding member at least partially define a vapor-return chamber in fluid connection with the at least one vapor aperture.
According to an embodiment of the invention, said connection element and said central body are arranged so that the smallest said passage section for the steam flow flowing through said duct is greater than 25mm2。
This feature allows to avoid excessive restrictions on the passage section, which leads to an accelerated steam flow, which may entrain water droplets in a more drastic manner in the direction of the steam hole or holes of the ironing plate.
According to an embodiment of the invention, said holding part is realized in a plastic material. These arrangements allow to avoid overheating the steam flow passing through the retaining means and thus to avoid that the steam flow exiting the steam iron is too dry. The retaining means according to such an embodiment thus allow to retain a substantial part of the water droplets entrained by the steam flow, while at the same time ensuring a jet of a humid steam flow at the outlet of the steam vents of the steam iron. However, the holding member may be realized by other materials, for example, by aluminum or copper.
According to an embodiment of the invention, said connecting element is constituted by a blade.
According to an embodiment of the invention, each connecting element is inclined with respect to the longitudinal axis of the catheter.
According to another embodiment of the invention, each connecting element is substantially perpendicular with respect to the longitudinal axis of the catheter.
According to an embodiment of the invention, the connection element is helically arranged in the catheter.
According to an embodiment of the invention, said retaining means comprise a first series of lower connecting elements extending substantially in a first plane of extension and a second series of upper connecting elements extending substantially in a second plane of extension longitudinally staggered with respect to the first plane of extension.
According to an embodiment of the invention, the lower connecting element is angularly offset with respect to the upper connecting element.
According to an embodiment of the invention, the lower connecting elements are regularly spaced from each other and the upper connecting elements are regularly spaced from each other.
According to an embodiment of the invention, the connecting elements each have two mutually opposite end edges and are connected respectively to the tubular peripheral wall and to the central body, the connecting elements each also having two mutually opposite side edges, the connecting elements each comprising at least one retaining rib extending downwards starting from the respective side edge. These arrangements allow stopping the flow of water droplets at the edge of each connecting element and thus further improving the retention of water droplets in the retaining device according to the invention.
According to an embodiment of the invention, each side of each connecting element may for example be straight or curved.
According to an embodiment of the invention, the connecting elements each have an L-shaped or U-shaped cross section.
According to an embodiment of the invention, the holding part is a single piece.
According to an embodiment of the invention, the retaining means comprise a first retaining portion defining the lower portion of the tubular peripheral wall of the duct and a second retaining portion defining the upper portion of the tubular peripheral wall of the duct, the first and second retaining portions being assembled to each other.
This feature allows for simplified manufacture of the retaining member by moulding to achieve more complex shapes.

According to an embodiment of the invention, said connecting elements each extend radially from the tubular peripheral wall of said catheter up to said central body.
According to an embodiment of the invention, the connecting elements are each substantially flat and extend parallel to the longitudinal axis of the catheter.
According to an embodiment of the invention, the retaining means comprise an annular retaining rib extending downwards from the lower surface of the connecting element.
Such ribs allow to form a barrier that provides for the water droplets that are kept under the connecting element, from flowing along the surface of the element towards the upper opening of the duct.
According to an embodiment of the invention, said annular retaining rib and the central body are coaxial.
According to an embodiment of the invention, said central body is elongated and extends substantially parallel to the longitudinal axis of the catheter.
According to an embodiment of the invention, the central body comprises a tubular side wall comprising a first open end positioned towards the downward access opening and a second end opposite the first open end, and a blocking wall blocking the respective second end.
According to an embodiment of the invention, the tubular peripheral wall comprises a lower end edge and an upper end edge, the central body projecting beyond the upper end edge of the tubular peripheral wall.

According to an embodiment of the invention, the steam distribution circuit further comprises a decompression chamber (chambrede retete) arranged upstream of the holding means and configured for reducing the flow speed of the steam flow before it reaches the holding means. These means allow to increase the duration of the passage of the steam flow in the soleplate of the steam iron and thus to favor, on the one hand, the evaporation of a greater part of the water droplets upstream of the retaining means and, on the other hand, the improvement of the effectiveness of the retaining means.
According to an embodiment of the invention, said decompression chamber is arranged so that the smallest said passage section for the steam flow flowing through said decompression chamber is greater than 25mm2。

Detailed Description
It is noted that in this document, the terms "horizontal", "vertical", "below", "above", "front", "rear", which are used to describe the steam iron, refer to the steam iron in a situation of use, when the ironing board is placed on a horizontal plane.
Fig. 1 shows an ironing device 2, said ironing device 2 comprising a base unit 3, a steam iron 4 and a steam delivery conduit 5, said steam delivery conduit 5 connecting said base unit 3 and said steam iron 4. The base unit 3 comprises inter alia a steam generator 6, a water container 7 and a pump 8, the pump 8 being configured for supplying the steam generator 6 with water from the water container 7, and the steam iron 4 comprises inter alia a grip portion 10 and a soleplate 9.
As shown in particular in fig. 6, the soleplate 9 comprises a main body 11, a covering portion 12 at least partially covering the main body 11 and an ironing plate 13 extending below said main body 11. The ironing board 13 comprises a substantially flat ironing surface 14 and steam vents 15 opening into the ironing surface 14. Advantageously, the main body 11 and the ironing plate 13 are realized by a material that is thermally conductive.
The body 11 and the cover portion 12 define a steam distribution circuit 16, said steam distribution circuit 16 being fluidly connected on the one hand with the steam generator 6 through the steam delivery conduit 5 and on the other hand with the steam vents 15. Said steam distribution circuit 16 comprises, in particular, a steam flow inlet 16.1 connected to said steam delivery conduit 5. Thus, a steam flow can flow into said steam distribution circuit 16 and up to the steam vents 15.
The steam iron 4 is equipped with heating means 17 integrated in the main body 11 of the soleplate 9, said heating means 17 being configured for heating the ironing plate 13 and said main body 11.
More specifically, as shown in fig. 4 to 11, the steam iron 4 further comprises retaining means 18 arranged along the steam distribution circuit 16, said retaining means 18 being configured for retaining water droplets entrained by said flow of steam flowing in said steam distribution circuit 16 and for evaporating said retained water droplets.
The holding means 18 comprise a holding part 19 covered by said cover part 12. According to the embodiment shown in fig. 4 to 11, the retaining part 19 is a single piece and may be realized, for example, by a plastic material.
The holding member 19 comprises a conduit 21, the conduit 21 comprising a tubular peripheral wall 22 and having a longitudinal axis a. The tubular peripheral wall 22 comprises a lower inlet opening 23 through which said flow enters said duct 21 and an upper outlet opening 24 through which said flow exits said duct 21 through said upper outlet opening 24. According to the embodiment shown in fig. 4 to 11, the tubular peripheral wall 22 is frustoconical, but may of course also be cylindrical.
The holding member 19 further comprises a central body 25 arranged at the centre of the conduit 21. According to the embodiment illustrated in fig. 4 to 11, the central body 25 extends along the longitudinal axis a of the duct 21 and has a substantially ogival shape. Said central body 25 more particularly comprises a tubular side wall 26, said tubular side wall 26 comprising a first open end 26.1 oriented towards the downward access opening 23, and a second end 26.2 opposite said first open end 26.1, and a blocking wall 30, said blocking wall 30 blocking the second end 26.2 of the tubular side wall 26. Notably, said central body 25 may optionally project beyond the upper end edge of the tubular peripheral wall 22.
The retaining member 19 further comprises a plurality of connecting elements 27 extending through the duct 21, said plurality of connecting elements 27 connecting the tubular peripheral wall 22 and the central body 25. Said connecting element 27 and central body 25 cover at least 60%, and preferably at least 90%, of the passage section of said duct 21 in a projection plane perpendicular to the longitudinal axis a of said duct 21. Advantageously, said connection element 27 and central body 25 are arranged so that the smallest said passage section for the steam flow flowing through said duct is greater than 25mm2. These different arrangements allow, on the one hand, a greater load (charge) loss to be generated inside the retaining device, which facilitates the separation of the water droplets from the water vapor, and, on the other hand, a blocking of the passage of the water droplets and thus ensure the retention of a greater amount of water droplets entrained by the steam flow.
According to the embodiment illustrated in fig. 4 to 11, each connecting element 27 is constituted by a blade which extends from the tubular peripheral wall 22 as far as the central body 25. Advantageously, the connecting element 27 is inclined with respect to the longitudinal axis a of the duct 21 and is helically arranged in said duct 21. Furthermore, the width of each connecting element 27 increases in the direction of the tubular peripheral wall 22.
Each connecting element 27 has two end edges 27.1 opposite each other and two side edges 27.2 opposite each other, said two end edges 27.1 being connected respectively to the tubular peripheral wall 22 and to the central body 25. According to the embodiment shown in fig. 4 to 11, each lateral edge 27.2 is curved and each connecting element 27 comprises a retaining rib 28 extending downwards from a respective one of the lateral edges. Each connecting element 27 thus has a cross-section in the shape of an L. These arrangements allow the flow of water droplets to be prevented at the edge of each connecting element 27 and thus the retention of the water droplets in the retaining device 18 according to the invention to be further improved.
The holding device 18 further comprises a support portion 29 arranged on the bottom plate 9, and the support portion 29 is more particularly arranged on the main body 11. The support portion 29 comprises a bottom wall 29.1 and a side wall 29.2, said side wall 29.2 extending from the bottom wall 29.1 and the holding member 19 being mounted on the side wall 29.2. The retaining member 19 may, for example, comprise an abutment flange 31, said abutment flange 31 extending around the lower edge of said tubular peripheral wall 22 and abutting against the side wall 29.2 of the support portion 29.
The holding member 19 and the support portion 29 delimit an evaporation chamber 32, said evaporation chamber 32 being arranged upstream of the connection element 27 with respect to the flow direction of the steam flow, and more specifically below the connection element 27. The water droplets separated from the steam flow by the connecting element 27 fall by gravity into the evaporation chamber 32.
The holding device 18 further comprises a steam inlet 33 (shown in fig. 4) arranged in the side wall 29.2, and the steam flow enters the evaporation chamber 32 through the steam inlet 33. According to the embodiment shown in fig. 4 to 11, the steam inlet 33 is partially defined by the duct 21.
Since the body 11 is realized by a heat-conducting material, a part of the heat generated by the heating means 17 is conducted to the evaporation chamber 32, so that water droplets falling by gravity into the evaporation chamber 32 are evaporated and can thus be carried to the outside of the evaporation chamber 29 and carried by the steam flow towards the steam vents 15.
As shown in fig. 4 and 5, the steam distribution circuit 16 comprises a decompression chamber 34 arranged upstream of the holding means 18, said decompression chamber 34 being configured for reducing the flow speed of the steam flow before it reaches said holding means 18 and more specifically the holding means 19. Advantageously, the decompression chamber 34 comprises a single deflecting baffle 34.1 extending between said steam flow inlet 16.1 and the retaining means 18.
The vapor distribution circuit 16 further comprises a vapor return chamber 35, said vapor return chamber 35 being defined by the cover portion 12 and the holding member 19. The vapor return chamber 35 is disposed downstream of the upper discharge opening 24 and is fluidly connected to the vapor vents 15.
Advantageously, the steam distribution circuit 16 further comprises a plurality of spikes 40 extending in the vicinity of the steam flow inlet 16.1. The presence of these spikes 40 allows to increase the interaction area between the steam flow and the steam distribution circuit 16 and therefore facilitates the separation of the steam flow and the water droplets flowing through the steam distribution circuit 16.
Fig. 12 to 19 show a holding device 18 according to a second embodiment of the invention, which differs from the first embodiment mainly in that the holding member 19 comprises a first holding portion 19.1 defining the lower part of the tubular peripheral wall 22 of the duct 21, and a second holding portion 19.2 defining the upper part of the tubular peripheral wall 22 of the duct 21, and in that said first and second holding portions 19.1 and 19.2 are assembled to each other.
The first retaining portion 19.1 comprises a first tubular peripheral portion 22.1, a first central body portion 25.1 arranged at the centre of the first retaining portion 19.1 and a plurality of connecting elements 27 connecting the first tubular peripheral portion 22.1 and the first central body portion 25.1, and said second retaining portion 19.2 comprises a second tubular peripheral portion 22.2, a second central body portion 25.2 arranged at the centre of the second retaining portion 19.2 and a plurality of connecting elements 27 connecting the second tubular peripheral portion 22.2 and the second central body portion 25.2.
The first central body portion 25.1 comprises a male assembly element 36, while the second central body portion 25.2 comprises a female assembly element 37 configured for cooperating with said male assembly element 36. The male assembly element 36 may for example comprise an assembly portion of truncated cone shape, while the female assembly element 37 may for example comprise an assembly receptacle configured for receiving the assembly portion of truncated cone shape. The male assembly element 36 and the female assembly element 37 can also be equipped with angular indexing elements (ment d' index angulare).
According to a second embodiment of the invention, each connecting element 27 is also constituted by a blade, but extends perpendicularly with respect to the longitudinal axis a of the duct 21. Furthermore, according to this embodiment, the retaining means 19 comprise a first series of lower connecting elements 27 and a second series of upper connecting elements 27, the lower connecting elements 27 of the first series extending in a first plane of extension and being regularly spaced from each other, the upper connecting elements 27 of the second series extending in a second plane of extension longitudinally offset with respect to the first plane of extension and being regularly spaced from each other, the lower connecting elements 27 being angularly offset with respect to the upper connecting elements 27.
Furthermore, according to the second embodiment of the invention, each connecting element 27 comprises two retaining ribs 28, said two retaining ribs 28 extending downwards starting from the respective side edge 27.2. Each connecting element 27 thus has a U-shaped cross section.
Fig. 20 to 25 show a retaining device 18 according to a third embodiment of the invention, which differs from the first embodiment mainly in that said central body 25 has a substantially dome shape and in that each connecting element 27 extends radially from the tubular peripheral wall 22 of the duct 21 up to the central body 25 and parallel to the longitudinal axis a of the duct 21.
According to the embodiment shown in fig. 20 to 25, the retaining part 19 further comprises an annular retaining rib 38 extending downwards from the lower surface of the connecting element 27.
The invention is of course in no way limited to the embodiments shown and described, which are given by way of example only. Changes may be made, especially in matters of construction of different elements or by substitution of technical equivalents, without exceeding the scope of the invention.
Thus, in a variant not shown, the evaporation chamber located upstream of the retaining element can be replaced by a water storage area in which a pump can draw in order to supply water to the spray nozzle of the atomizer carried by the iron.
