    [0001] The present invention relates to an ironing appliance comprising a steam generator fed by a water reservoir separate from the steam generator and a steam generator comprising a steam generator fed by a water reservoir separate from the steam generator. relates more particularly to an apparatus comprising a device for the diffusion of an anti-scale agent in the water sent to the steam generator, the apparatus comprising a steam distribution circuit comprising at least one filter for retaining scale particles carried by the vapor stream. It is known from patent application US 6,427,366, an iron comprising an instantaneous vapor type steam generator fed by a water tank separate from the steam generator, the water tank comprising an antiscaling agent . In this document, the vapor produced by the steam generator is distributed to steam outlet holes by a circuit comprising a filter gate filtering the scale particles transported by the steam flow at the outlet of the vaporization chamber. Such an iron has the advantage of having an antiscaling agent which allows, to a large extent, to transform the scale produced by the evaporation of water in the vaporization chamber into fine powder that can be removed with the vapor diffused through the steam outlet holes and possess, in addition, a filter that retains the largest particles of scale, preventing them from being emitted by the steam outlet holes of the sole and not stain the laundry. However, such an iron has the disadvantage of having performance, including a steam flow at the outlet of the sole, which can decrease over time due to the progressive clogging of the filter and scaling of the chamber Spraying. This clogging is even faster than the degree of filtration is important, that is to say that the filter allows the retention of smaller scale particles.
    [0002] It is therefore an object of the present invention to provide an ironing apparatus which overcomes these disadvantages. For this purpose, the invention relates to an ironing apparatus comprising a steam generator, a tank, separate from the steam generator, supplying the steam generator with water, and a steam distribution circuit coming from the steam generator. vapor comprising at least one filter for retaining scale particles carried by the vapor stream, the apparatus comprising a device for diffusing an anti-scale agent into the water from the tank, before it is transferred to the steam generator characterized in that said filter 10 is removable from the apparatus for cleaning. The apparatus thus produced has the advantage of having a filter which can be easily extracted from the apparatus for its inspection and its possible cleaning in order to avoid a degradation of the performance of the ironing apparatus. By "removable" filter is meant a filter that can be removed from the apparatus without requiring disassembly of the apparatus by means of a tool. The term "scale" is intended to define deposits based essentially calcium carbonate CaCO3 and / or magnesium carbonate MgCO3, which form solid accumulations likely to reduce the performance and life of the device.
    [0003] By "anti-scale agent" is meant an agent for suppressing or at least reducing scale deposition in the vaporization chamber. In particular, the term "anti-scaling agents" is understood to mean inhibiting agents which prevent germination and / or growth of scale in the steam generator, in particular avoiding adherence of the scale to the walls of the steam generator, such as phosphonate crystals, or curative agents that help dissolve scale, such as citric acid. According to another characteristic of the invention, the filter is fixed on a support element removably mounted in the distribution circuit, sealing means being arranged at the interface between the support element and the distribution circuit. Such a characteristic makes it possible to avoid the passage of the vapor flow between the support element and the pipe so that the flow of vapor passes mainly through the filter. According to another characteristic of the invention, the apparatus comprises a scale discharge orifice which communicates with a portion of the distribution circuit 5 located upstream of the filter. Such a scale discharge orifice allows the evacuation of scale particles present in the steam distribution circuit and which are retained upstream of the filter. According to another characteristic of the invention, the filter is removable from the apparatus 10 by the scale discharge orifice. Such a characteristic makes it possible to have a single orifice making it possible at the same time to evacuate the scale particles and to extract the filter from the apparatus for its inspection. According to another characteristic of the invention, the scale discharge orifice is closed by a removable plug accessible from the outside of the apparatus. According to another characteristic of the invention, the filter is secured to the plug. Such a characteristic makes it possible to have a filter which is automatically removed from the apparatus when the plug is removed, allowing a systematic inspection of the state of the filter by the user when a scale removal operation is performed. Such a feature also reduces the number of manipulations that the user must perform to access the filter and to avoid that the user forgets to return the filter after cleaning. According to another characteristic of the invention, the filter comprises a scale-collecting container which is introduced through the scale discharge orifice into a scale recovery cavity provided upstream of the filter. Such a characteristic has the advantage of allowing the removal of scale by simply removing the tartar recovery container. According to another characteristic of the invention, the filter is constituted by a grid 30 with openings less than 0.6 mm side, and advantageously less than 0.4 mm, the grid advantageously having a surface greater than 5 cm 2 and preferably greater than 8 cm 2. The small size of the openings makes it possible to let only tartar particles that are little or not visible to the naked eye towards the steam outlet holes. The large surface area of the filter makes it possible to provide a cumulative passage section through the pores of the filter which is large enough to maintain an acceptable vapor flow rate despite partial clogging of the filter. In addition, such a filtration surface makes it possible to obtain charge losses compatible with the diffusion of a steam flow advantageously greater than 10 g / min, and preferably greater than 30 g / min, with a steam generator constituted by an instantaneous vaporization chamber fed conventionally by a drip. According to another characteristic of the invention, the filter is disposed downstream of a zone of the steam distribution circuit where the steam flow makes a sudden change of direction, preferably of at least 90 °. Such a feature has the advantage of limiting the clogging rate of the filter, the heavier particles being driven, due to their inertia, outside the filter, in a storage area. According to yet another characteristic of the invention, the steam outlet holes are formed in an ironing soleplate of an iron. According to yet another characteristic of the invention, the flow of vapor traveling in the steam distribution circuit flows upwardly through the filter when the iron rests horizontally on its sole. Such a characteristic has the advantage of blocking the particles against the underside of the filter so that these particles are released by gravity of the filter when stopping the flow of steam. According to another characteristic of the invention, the iron has a heel on which it can rest during the inactive ironing phases. According to another characteristic of the invention, the steam generator is a flash chamber. Such a feature has the advantage of providing a simple construction for producing steam. According to another characteristic of the invention, the anti-scale agent is a phosphonate compound, or a polyphosphate such as sodium hexametaphosphate or a biodegradable anti-scalant agent as described in the patent application filed in France by applicant under the application number FR1453381. According to another characteristic of the invention, the device for the diffusion of the anti-scale agent is placed in the water tank. Such a characteristic makes it possible to disperse the anti-scale agent directly into the water storage zone, where the latter has a tendency to stagnate, which makes it possible to have a better diffusion of the slow diffusion anti-scale agents. According to another characteristic of the invention, the filter has a convex shape. Such a characteristic has the advantage of causing a slippage of the water droplets along the curved shape of the filter, this flow of water droplets having the advantage of taking away some of the scale particles attached to the filter. , thus participating in its cleaning. According to another characteristic of the invention, the tartar recovery vessel has an open front end through which the vapor flow enters and a closed rear end, the container having a side window through which the vapor flow escapes in the direction steam outlet holes, the filter extending through the window. Such a characteristic makes it possible to benefit from the entrainment effect of the flow of vapor passing through the container in order to increase the quantity of scale recovered in the container, the particles being trapped inside the tartar recovery container by the filter. According to another characteristic of the invention, the tartar recovery container comprises at least a part, extending behind the filter, defining a storage volume.
    [0004] Such a feature has the advantage of allowing scale particles to be stored in an area away from the filter when the apparatus is arranged such that the container is oriented substantially vertically with the posterior end. closed down. Advantageously, the storage volume of the tartar recovery container is greater than 4 cm3.
    [0005] Such a characteristic makes it possible to collect the tartar particles accumulated between two interviews, as well as the non-vaporized water in the vaporization chamber, without contaminating the filter. According to another characteristic of the invention, the tartar recovery container comprises, on the wall opposite the window, a spoon comprising a hollow portion. According to another characteristic of the invention, the instantaneous vaporization chamber is connected to the scale recovery cavity through an opening at the rear end of the vaporization chamber, the vapor flow produced by the vaporization chamber. escaping through the steam distribution circuit through the opening at the rear of the vaporization chamber. According to another characteristic of the invention, the scale discharge orifice opens at the heel of the iron. Such a feature has the advantage of providing excellent access to the scale outlet 20 when the iron rests on its sole. According to another characteristic of the invention, the scale recovery cavity is cantilevered behind the sole when the iron rests on its sole. Such a characteristic makes it possible to move the cavity of the scale away from the soleplate and thus to limit the risk of burns during handling of the plug. According to another characteristic of the invention, the device for the diffusion of the antiscaling agent may be removable from the apparatus, for example presenting the form of a cassette.
    [0006] Such a feature makes it easy to exchange the device for a new one when the anti-scale agent is being depleted. The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention presented by way of non-limiting example, with reference to the appended drawings. in which: - Figure 1 is a perspective view of an iron according to a particular embodiment of the invention; - Figure 2 is a longitudinal sectional view of the heating body and the sole equipping the iron of Figure 1; Figure 3 is a perspective view of the heating body of Figure 2 without its closure cap; - Figure 4 is a top view of the heating body of Figure 2; FIGS. 5 and 6 are perspective views, partially broken away, of the heating body of FIG. 2 respectively with and without the tartar recovery container; - Figure 7 is a perspective view of the tartar recovery container fixed on the plug fitted to the iron of Figure 1. Only the elements necessary for the understanding of the invention have been shown. To facilitate the reading of the drawings, the same elements bear the same references from one figure to another. FIG. 1 illustrates a steam iron 1 comprising an ironing sole 10 provided with a set of steam outlet holes 10A, visible only in FIG. 2, the sole 10 being surmounted by a plastic housing comprising a handle 11 at its upper end and a heel 12 in its rear part on which the iron can rest substantially vertically during the inactive ironing phases. The heel 12 comprises two arms delimiting between them a space receiving a removable plug 13 giving access to a scale discharge orifice 50, visible in FIG. 2, the plug 13 being fixed on a rear surface of the case by a fastening bayonet type similar to that described more in detail in the patent application FR 2 981 371 filed by the applicant, the rear surface of the housing being slightly inclined forward to provide easier access when the iron rests horizontally on his sole 10.
    [0007] The box of the iron 1 comprises, in a manner known per se, a water tank 14, having walls advantageously transparent, containing water intended to feed a vaporization chamber 3, visible in FIG. Water tank 14 comprises a device 15 for the diffusion of an anti-scale agent. This device 15 may, for example, allow the progressive diffusion of a preventive agent for the germination and / or growth of scale in the vaporization chamber. As a preferred example, the device 15 will ensure the diffusion of polyphosphate, such an agent having the advantage of preventing scale from adhering to the walls of the vaporization chamber 3 and allowing the release of scale in the form particles of relatively large size, easily filterable. The device 15 may also comprise a microporous structure releasing sodium hexametaphosphate, as described in patent FR 2 757 364, and / or be constituted by a device allowing the diffusion of a phosphonate compound such that this is described in patent EP 0 610 997. The device 15 for the diffusion of anti-scale agent may also allow the diffusion of a biodegradable anti-scalant agent, as described in the patent application filed by the applicant under the application number FR 1 453 381, such an anti-scale agent having the advantage of not being pollutant. Of course, the device 15 may also combine the diffusion of these agents, such a combination having the advantage of allowing the dissolution kinetics different from the anti-scale agents to be obtained for an optimal effectiveness of the anti-scale action whatever the intensity. of use of the device.
    [0008] Thus, the device 15 may allow the diffusion of a slow diffusion antiscaling agent, such as polyphosphate, and a rapid diffusion antiscaling agent, such as sodium hexametaphosphate. The device may also allow the diffusion of an acidic scale inhibitor having a curative action on scale, rather than a preventive action. By way of example, this curative anti-scaling agent may be composed of a citric or sulphamic acid. This anti-scale acidic agent may be in the form of a liquid or a gel distributed in the water of the tank 15 by means of a metering pump, or by means of a porous membrane delivering the agent 10 by gravity or by osmotic pressure balance. The anti-scale acidic agent may also be in the form of a pellet of dehydrated acid salt. According to Figures 2 to 4, the soleplate 10 of the iron is thermally and mechanically bonded to a heating body 2 integrated in the lower part of the housing, the heating body 2 comprising an aluminum foundry 15 conventionally comprising a resistive element 20 bent into horseshoe and a boss 21, visible in Figure 3, for receiving a temperature control thermostat of the sole 10. The heating body 2 comprises a peripheral wall 22 which laterally delimits a space comprising a main vaporization chamber 3 20 and a vaporizer type evaporator chamber 4, having a bottom having a plurality of pyramidal pads for increasing the heat exchange surface. The vaporization chamber 3 is disposed at the center of the heating body 2 and is connected to the steam outlet holes of the soleplate 10 by a vapor distribution circuit comprising two lateral channels 30 extending on either side of the vaporization chamber 3 and joining at the front end and at the rear end of the heating body 2. The side channels 30 conventionally comprise orifices 31 passing through the heating body 2 to open on the lower face of the heating body, at the level of Vapor dispensing cavities 33, visible in Figure 2, disposed opposite the steam outlet holes 10A of the sole. According to FIGS. 2 and 5, the heating element 2 also comprises a closure plate 24 which rests on the upper edge of the peripheral wall 22, this closure plate 24 being surmounted by the water reservoir 14, visible on the 1, supplying water to the vaporization chamber 3 through an orifice 24A of the closure plate 24 receiving, in a manner known per se, a drip-shaped plug, not shown in the figures, allowing the production of a continuous steam flow of the order of 20 to 70 gr / min. The main vaporization chamber 3 is delimited laterally by a partition 23 going up to the closure plate 24, being sealed with the latter, so that the vapor produced in the vaporization chamber 3 can not be produced. escape only through an opening 23A formed in the partition 23 at the rear end of the vaporization chamber 3. As can be seen in Figure 2, the opening 23A of the partition opens on a conduit 25, section substantially oblong cross section, made in the foundry of the heating body 2, this duct 25 extending obliquely with respect to the plane of the sole 10, at an angle of the order of 20 °, and being extended by a collector 5 in plastic material, for example of the PPS (phenylene polysulfide) type, integrated into the casing of the iron 1. The collector 5 comprises a cavity 51 for the recovery of scale extending axially in the extension duct 25 and opening on the heel 12 of the iron at the scale discharge orifice 50 closed by the plug 13, the cavity 51 being cantilevered behind the sole 10 when the iron rests on its sole 10 and having an oblong cross section.
    [0009] As can be seen in FIGS. 2 and 6, the manifold 5 has an exhaust opening 53 in the upper part of the cavity 51 for recovering scale, this exhaust opening 53 opening into a return channel 54. extending above the conduit 25 and opening into a distribution chamber 26 disposed at the inlet of the two lateral channels 30.
    [0010] According to FIGS. 5 and 7, the tartar recovery cavity 51 receives a removable tartar collecting vessel 6 having a shape complementary to the tartar recovery cavity 51, the tartar recovery vessel being extractable or introduced into the tartar recovery cavity 51. the cavity 51 through the scale discharge orifice 50. The container 6 has an open front end 60 through which the flow of vapor emitted by the vaporization chamber 3 is admitted into the container 6 and a closed rear end 5 advantageously fixed at the plug 13, as is illustrated in FIG. 7. The container 6 comprises a lower part provided with a tartar retention spoon 64 having a hollow part in which the scale particles are stored, the front end of the spoon having a step 64A to prevent the scale recovered in the spoon 64 does not return by gravity in the ch amber vaporization when the iron 1 is disposed on its sole 10. The container 6 is preferably made of plastic material, polyamide type PA 6-6 reinforced with 30% glass fiber, and supports a first and a second seals 61, 62 of silicone coming into contact with the inner wall of the cavity 51 for the recovery of scale, the container 6 having, between the two seals 61, 62, an opening formed in the upper half of the container 6 forming a lateral window 63 coming opposite the exhaust opening 53 of the cavity 51 for the recovery of scale when the container 6 is integrally introduced into the cavity 51.
    [0011] According to FIG. 7, the tartar recovery vessel 6 comprises a filter 7 constituted by a convex filtering grid extending through the window 63, this filtering grid 7 being fixed at the edge of the window and advantageously being covered. a hydrophobic and / or non-stick coating such as PTFE (polytetrafluoroethylene). Preferably, the scale collecting container 6 is overmoulded at the edge of the filtration grid 7 so as to ensure a perfect attachment of the grid 7 to the container 6. The filtering grid 7 has calibrated openings for retaining the particles. Larger scale and has a size adapted to provide a passage section sufficient for the required steam flow. By way of example, the grid 7 may comprise square openings of less than 0.6 mm per side, and preferably between 0.1 mm and 0.4 mm, the surface of the grid being at least 8 cm 2 for square openings of 3033339 12 0.2 mm and a steam flow rate of the order of 40 to 50 gr / min. The grid 7 will advantageously be made of stainless steel wire of the order of 0.1 mm in diameter or a smaller diameter. Preferably, the window 63 receiving the grid 7 is disposed in withdrawal relative to the front end 60 open so that the gate 7 is sufficiently far from the vaporization chamber 3 for the boiling water in the vaporization chamber 3 does not come, by projection, soil the filtering grid 7. In addition, the arrangement of the grid 7 in height on the container 6, when the iron rests on its sole 10, 10 avoids its defilement by water that can reach the cavity 51 as a result of incomplete vaporization of the water injected into the vaporization chamber 3 during an ironing session. The distance of the filtration grid 7 from the vaporization chamber 3, as well as the use of plastic materials for the collector 5 and the container 6, also have the advantage of making it possible to obtain a temperature relatively low in the environment of the grid 7, around 100 ° C, thus avoiding a strong vaporization of water that can reach the area of the container 6 located under the gate 7. Preferably, the window 63 is also remote the rear end of the container 6 so that a storage volume of the order of 4 to 5 cm 3 results in the part of the container 6 situated between the bottom of the container 6 and the grid 7, in which the Tartar particles fall when the iron 1 is placed vertically on its heel 12. The flow of the steam stream in the iron 1 thus made will now be described. When the water from the drip-shaped box reaches the bottom of the vaporization chamber 3, it vaporizes instantly, which causes the release of a stream of vapor, illustrated by arrows in FIGS. 2 to 5, which escapes through the opening 23A of the partition 23 and then flows successively, through the outlet conduit 25, the container 6, the gate 7, the return channel 54 and the lateral channels 30, the flow steam then passing through the orifices 31 to open on the underside of the soleplate 10 and escape through the outlet holes 10A of the soleplate. Since the vaporized water is loaded with an anti-scale agent, following its residence in the tank 14 equipped with the device 15, the vaporization of the water is essentially accompanied by the formation of small scale particles, smaller than the size of the openings of the grid 7, so that these particles are transported by steam and gradually diffused by the steam outlet holes of the sole 10, without this being perceptible by the user. However, the evaporation of the water from the vaporization chamber 3 may, in the long term, following the exhaustion of the antiscaling agent, or because of its partial efficiency, create the formation of a layer of calcium in the bottom of the vaporization chamber 3 which will gradually disintegrate into larger scale particles, especially under the effect of the expansion of the heating body 2 during the cooling phases between two ironing sessions.
    [0012] The largest scale particles present in the vaporization chamber 3 are progressively carried away by the flow of steam in the conduit 25 and are partly sent, because of their inertia, into the bottom of the tarsal recovery container 6 where they are trapped so that they fall by gravity into the spoon 64 and partly sent to the grid 7. This inertial separation of the scale particles is effected in particular through the turn of the order of 90 ° that effected the flow of vapor at the inlet of the grid 7. The displacement of the largest scale particles to the container 6 is also performed by gravity each time the iron 1 is placed on its heel 12, the volume of storage formed in the bottom of the container 6 being adapted to receive the scale particles, accompanied by any drops of water, without the latter coming into contact with the grid 7, avoiding a In the stopping of the steam, most of the particles trapped by the grid 7 30 fall by gravity into the spoon 64 of the container 6, although some particles may remain stuck on the grid 7 and contribute the progressive clogging of the latter, the grid 7 also scaling due to evaporation of any droplets of water coming into contact with the grid 7. When cleaning the iron 1 is necessary, it that is, after several steam ironing sessions, or when an alert indicator is activated on the iron, the user can easily extract most of the tartar present in the iron by placing the iron 1 horizontally on its sole 10, so as to easily access the cap 13, and extracting the recovery container 6 of the cavity 51 by unlocking the cap 13 and moving it backwards e in such a way as to slide the container 6 axially through the scale discharge orifice 50. During this extraction from the container 6, the tartar is preserved in the spoon 64 thanks to the hollow shape of the latter and to the presence of the step 64A near the front end of the spoon.
    [0013] The contents of the container 6 can then be emptied and the container 6 can be passed under tap water for cleaning. During this scale removal operation, the user has direct visual access to the state of the filtering grid 7 so that he immediately realizes its state of cleanliness. If he deems it necessary, he may clean the grate 7 by rubbing it under the water with a brush or by immersing it in a descaling liquid. The iron thus produced has the advantage of permanently avoiding any visible rejection of scale particles on the laundry. Indeed, the presence of an anti-scale agent in the water of the tank allows both to delay the formation of scale particles but also to reduce the size of these particles so that the iron will be able to operate for a long time. period without requiring cleaning of the filter grid, most of the scale particles carried by the vapor having a size smaller than the openings of the grid and only the largest particles being retained upstream of the grid. Thus, such a combination can greatly increase the time interval between two cleaning operations of the filter grid. In addition, the iron thus produced allows easy removal of the scale particles recovered with the help of the tartar recovery container 3033339 so that it can be very easily maintained in a state of cleanliness conducive to optimal operation of the iron. In particular, the iron thus produced has the advantage of allowing the user to have a direct visual control of the state of fouling of the filtering grid 5 during the extraction of the tartar harvesting container. so that the user can judge immediately, when performing such an operation, if it is necessary to clean the filter grid. Of course, the invention is not limited to the embodiment previously described and illustrated which has been given by way of example. Modifications are possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention. Thus, in an embodiment variant not shown, the device for the diffusion of anti-scale agent may be arranged, not directly in the water tank, but in the supply circuit connecting the water tank to the vaporization chamber, preferably in a buffer zone dedicated for this purpose. In another alternative embodiment, the device for the diffusion of the anti-scale agent may also be placed at the inlet of the tank so that the agent is diffused in the water during filling of the tank. In another variant embodiment, the device for the diffusion of the antiscaling agent may be placed in an area of the iron which is supplied with water only during specific phases of use of the iron, for example when the iron is placed on its heel or the opposite is placed on the sole. Such a variant has the advantage of preserving the life of the device by limiting only to certain phases of use, the diffusion of the anti-scale agent. Thus, in an alternative embodiment of the invention not shown, the tartar recovery container may not be fixed on the cap but have, at its rear end, a handle allowing it to be entered manually by the user after the removal of the cap.
    [0014] Thus, in another variant embodiment not shown, the filter may be removable from the apparatus through an opening which is distinct from the scale discharge orifice, the filter being for example extractable on one side of the apparatus. . Thus, in another variant embodiment, not shown, the filtering grid may be removably mounted on the tartar recovery container so that the filtering grid can be changed if necessary. Thus, in an embodiment variant not shown, the iron may comprise different successive filters with more and finer filter mesh. At least a portion of these filters, and preferably the filters with the finer meshes, will be disposed on the tartar recovery vessel to allow easy cleaning of the filters clogging the fastest. However, the iron may also include additional, non-removable filters inside the iron, downstream of the removable filters. Thus, in an alternative embodiment not shown, the vaporization chamber may be thermally decoupled from the sole, the latter may include its own heating element.
