    专利说明:

    [0001] The present invention relates to an ironing appliance comprising a housing containing a steam generator comprising a drain orifice for the removal of scale. and relates more particularly to an apparatus comprising a removable cap, accessible from the outside of the housing, closing the drain port, and comprising a cover hiding the cap.
    [0002] It is known, among the devices sold commercially, ironing appliances comprising a housing enclosing a tank for the generation of pressurized steam connected by a cord to an iron, the tank comprising a drain orifice, allowing the scale removal, closed by a removable cap, accessible from the outside of the case. In such devices, the cap is generally made of metal, to withstand the high temperatures prevailing in the tank, and is screwed on the drain hole. To prevent the user from getting rough by touching the metal part of the plug, the latter may be provided with a plastic part which is generally overmolded on the plug, such a plastic part may advantageously have a shape adapted to facilitate handling of the plug. plug. Such an overmolded cap, however, has the disadvantage of being relatively expensive to manufacture. In addition, with such a plug with a molded plastic part, the risk remains that the user is rude if he touches the plastic part of the cap during operation of the device because the latter is in direct contact with the party metal and its temperature rise gradually during the operation of the device. To overcome these disadvantages, it is known to cover the metal cap with a removable plastic cover which is fixed on the housing and no longer on the metal cap, such an independent plastic cover having the advantage of being inexpensive to produce and to ensure better thermal insulation.
    [0003] However, such a removable plastic cover has the disadvantage of being easily lost and uncomfortable to use so that the device is often used without the cover, with a risk of burn in case of contact with the plug.
    [0004] It is therefore an object of the present invention to overcome these disadvantages by providing an appliance having improved safety and usability. For this purpose, the subject of the invention is an ironing appliance comprising a housing containing a steam generator comprising a drain orifice 10 for the removal of scale, a removable plug which closes the drain orifice, accessible from the outside the housing, and a cover hiding the cap, characterized in that the cover is secured to the housing by a hinge, the cover can occupy a closed position in which it masks the cap and an open position in which it releases the access to the stopper. According to another characteristic of the invention, the cover is made of plastic material, advantageously polypropylene, the hinge being obtained directly from molding with the cover. Such a technical solution has the advantage of being very economical to implement. In addition, such a technical feature reduces the manufacturing cost of the device by reducing the number of assembly operations. According to yet another characteristic of the invention, at least part of the housing is obtained directly from molding with the cover and the hinge. According to yet another characteristic of the invention, the cover and the hinge are obtained directly from molding with a lower shell defining the base of the housing. According to yet another characteristic of the invention, the hinge is disposed under the drain orifice, the cover in open position extending under the outlet of the drain orifice and having a hollow shape which collects the liquid 30 '. flowing through the drain hole. Such a feature makes it possible to use the cover in the open position as a manifold of the liquid flowing from the drain orifice, which makes it possible to prevent the liquid from running anarchically along the housing, dirtying it, and does not enter the device. According to yet another characteristic of the invention, in the closed position, the cover 5 extends substantially vertically in front of the stopper and, in the open position, the cover comprises a free end, disposed opposite the hinge, which is inclined down. According to another characteristic of the invention, the cover comprises a cavity in which the stopper engages when the cover occupies the closed position, the cavity comprises a bottom wall bordered by a peripheral wall comprising a discharge opening, opening being advantageously raised with respect to the bottom wall. Such a feature allows the cache to be used as a pipe guiding the liquid from the drain port to a sink. In addition, such a cover also makes it possible to better visualize the quantity of tartar flowing through the drain orifice, the major part of the tartar being trapped in the cavity before flowing through the discharge opening. According to yet another characteristic of the invention, the hinge is bistable, the hinge being able to occupy a first stable position in which the cover 20 occupies the closed position and a second stable position in which the cover occupies the open position. Such a characteristic makes it possible to obtain very good ergonomics of use, the hinge ensuring automatic positioning of the cover in both positions.
    [0005] According to another characteristic of the invention, the hinge generates a return torque on the cover whose direction reverses when passing from an intermediate position between the closed position and the open position, the return torque tending to bring the hides to the closed position when the cover is in a first angular range between the intermediate position and the closed position and tending to bring the cover back to the open position when the cover is in a second angular range between the position 3035667 4 intermediate and open position. According to another characteristic of the invention, the hinge comprises a membrane disposed longitudinally between two rectilinear parts defining the axis of rotation of the hinge, the membrane having an almond shape, with two curvilinear edges joining at the end. rectilinear parts, the membrane deforming by seeing its curvature reverse when moving the cover between the open position and the closed position. According to another characteristic of the invention, when the cover occupies the open position, the membrane has a concave upper surface.
    [0006] Such a feature allows the hinge to channel water flowing from the drain port to the cover. According to another characteristic of the invention, the steam generator is constituted by a tank for generating steam under pressure which is connected by a cord to an iron.
    [0007] The aims, aspects and advantages of the present invention will be better understood from the following description of a particular embodiment of the invention given by way of non-limiting example with reference to the accompanying drawings. in which: - Figure 1 is a perspective view of an ironing apparatus according to a particular embodiment of the invention, with the cover of the drain orifice shown in the closed position; - Figure 2 is a perspective view, partially exploded, of the steam generating base equipping the apparatus of Figure 1, the cover being shown in the open position; Figure 3 is a perspective view of the base of Figure 2 when assembled, the cover being shown in an open position with the plug removed from the drain port of the vessel; FIG. 4 is a detail view, from below, of the cover equipping the apparatus of FIG. 1; Figure 5 is a sectional view along line V-V of Figure 4; - Figures 6 and 7 are detailed views, in perspective, of the cover 3035667 5 respectively in the open position and in the closed position. Only the elements necessary for the understanding of the invention have been represented. To facilitate the reading of the drawings, the same elements bear the same references from one figure to another. FIG. 1 represents an ironing apparatus, of the steam generator type, conventionally comprising an iron 1 and a steam generator base 2 connected to the iron 1 by a bead 3 allowing the transfer of steam from the base 2 to the iron iron 1, the base 2 being electrically powered by means of a cable, not shown in the figures. The base 2 generating steam comprises, in a manner known per se, a housing 20 enclosing a water tank 21 provided with a filling orifice 21A and a tank 4 for the generation of pressurized steam, shown in dashed lines in the figure 1. The tank 4 comprises a heating resistor 40 in the form of U, disposed under the bottom of the tank 4, which is regulated to allow the production of steam under a maximum pressure of the order of 4 to 6 bars, the tank 4 being supplied with water from the reservoir by a supply pipe 41 connected to a pump, not shown in the figures. The tank 4 also comprises a steam outlet orifice equipped with a solenoid valve 44 connected to the iron 1 by a steam duct integrated in the cord 3, the solenoid valve 44 being controlled at the opening by a knob 10 arranged under the handle of the iron 1. As can be seen in FIG. 2, the housing 20 is made by assembling plastic parts obtained by molding, and it comprises in particular a bottom shell 20A made of opaque polypropylene, which is surmounted by an intermediate shell 20B, also opaque polypropylene, and an upper shell 20C polypropylene transparent or translucent. The intermediate 20B and upper 20C shells are advantageously assembled to one another by overmolding a polypropylene seal, and they have complementary shapes forming between them a space defining the reservoir 21, the latter extending along 20. The lower shell 20A comprises a main body 22 which forms a base 3035667 6 supporting the tank 4, the latter comprising a lateral opening which communicates with a rigid conduit having an axial end provided with a drain hole 42 closed by a removable metal cap 43. As can be seen in FIGS. 2 and 3, the emptying orifice 42 opens on a lateral face of the casing 20 at an arch 23 formed in the intermediate shell 20B and in the upper shell 20C, the lower shell 20A comprising, facing this arch 23, a projecting support comprising a cradle 24 which is positioned under the conduit comprising the emptying orifice 42 and guarantee the correct positioning of the latter.
    [0008] The lower shell 20A also has a cover 5 which is connected to the main body 22 of the lower shell 20A by a hinge 6 obtained directly from the molding with the main body 22 and the cover 5, the hinge 6 being constituted by an area where the The thickness of the material is reduced. According to FIGS. 4 to 7, the hinge 6 is advantageously arranged at the lower end of the cover 5 so that the latter can occupy a closed position, illustrated in FIGS. 1 and 7, in which the cover 5 is arranged substantially vertically, by masking the plug 43 fixed on the emptying orifice 42, and occupy an open position, illustrated in particular in FIGS. 2, 3 and 6, in which the cover 5 is tilted downwards, forming an angle of the order of 45 ° relative to the horizontal, so as to release access to the closure cap 43, the cover 5 then extending under the outlet of the emptying orifice 42. As can be seen on 5, the hinge 6 comprises a rectilinear portion 60 at each of its longitudinal ends which defines the axis of rotation of the hinge 6, these straight portions 60 being advantageously constituted by a film of material having a thickness of the order e of 0.4mm. The hinge 6 also comprises a membrane 61 in the general shape of almond which is disposed between the two rectilinear parts 60, the membrane 61 comprising two curvilinear edges 62 joining at one end of the rectilinear parts 60. The membrane 61 is advantageously constituted by a film of material thickness of the order of 0.5 mm and has a curved shape deforming when the cover 5 moves from the open position to the closed position, the membrane 61 preferably having a concave shape when the cover 5 occupies the open position. The hinge 6 thus produced has the advantage of generating a return torque which, when the cover 5 is brought manually from the open position to the closed position, is opposed initially to the movement of the cover towards the closed position and tends to bring it back to the open position, this return torque to the open position corresponding to a first phase of deformation of the membrane 61. This first phase of deformation takes place until the cover 5 reaches a position intermediate where the curvature of the membrane 61 is reversed, and the return torque exerted by the latter, so that the cover 5 is then automatically returned to the closed position, the membrane 61 then having a convex shape. As can be seen in FIG. 6, the cover 5 has a hollow shape and comprises a cavity 50 comprising a bottom wall 51 having a shape complementary to that of the arch 23 and a peripheral wall 52 coming to engage on an edge 25 of the housing 20 delimiting the arch 23, the edge 25 comprising two symmetrical lateral bosses 26 engaging elastically in two grooves 53 formed on the peripheral wall 52 20 when the cover 5 occupies the closed position. The peripheral wall 52 comprises, at the free end of the cover 5 located opposite the hinge 6, a through opening 54 which allows the flow of any liquid present in the cavity 50 when the cover 5 occupies the position open, the housing 20 comprising a locking tab 27, 25 located at the top of the arch 23, which engages in the through opening 54 when the cover 5 occupies the closed position. The advantages of the cache thus realized will now be described. When the user wishes to use the apparatus, he places the cover 5 in the closed position, illustrated in FIG. 7, by lifting it and pressing on the cover 5 30 so that the lateral bosses 26 and the locking tab 27 carried by the housing 20 engage by elastic deformation respectively in the grooves 53 and the through opening 54 of the cover 5.
    [0009] The device can then be used without risk of burning the user, the metal cap 43 closing the emptying orifice 42 being then masked by the cover 5. In particular, in the closed position, the cover 5 presents the advantage of not being in thermal contact with the metal cap 43, but 5 is instead separated from the latter by a layer of air, so that the temperature of the cache 5 remains very low, even after a long period of time. use of the device. When the user wishes to perform a cleaning of the tank 4 to remove scale, or because it is invited by a light indicator on the device, or because he wants to ensure the status of cleanliness of the tank 4, it brings the device to the edge of a sink after ensuring that the device was stopped long enough for the tank 4 is at room temperature. The user then unlocks the cover 5 by pressing with the thumb on the locking tongue 27 inserted into the through opening 54 of the cover 5 and pulling laterally on the top of the cover 5 so that the lateral bosses 26 disengage grooves 53. Once the cover 5 has been unlocked, the user manually moves the cover 5 towards the open position, the membrane 61 of the hinge 6 then deforms 20 initially by generating a return torque which is opposes the movement of the cover 5 to the open position. When the cover 5 reaches the intermediate position where the curvature of the diaphragm 61 is reversed, the return torque generated by the diaphragm 61 changes direction and the cover 5 is then automatically brought into the open position, illustrated in FIGS. 6. The user then has access to the stopper 43 and can unscrew the latter by means of a screwdriver or a coin. When the plug 43 is extracted, the liquid contained in the tank 4 flows through the emptying orifice 42, taking with it any tartar particles present in the bottom of the tank 4. This liquid flows then by gravity in the cavity 50 of the cover 5, then in the sink through the opening 54 formed at the free end of the cache 5 5, the latter then playing the pouring spout function. During this emptying operation, the cover 5 has the advantage of channeling the liquid coming from the emptying orifice 42, thus preventing liquid from flowing anarchically along the housing 20 of the apparatus, with the risk of entering the interior of the latter. In addition, the cover 5 also has the advantage of allowing a better visualization of the scale particles exiting through the emptying orifice 42 so that the user can better appreciate the scaling state of the tank 4 and space in consequence the emptying operations. In particular, the opening 54 10 through the cover 5 may advantageously be located slightly back from the bottom wall 51 so that a step results in retaining any scale particles flowing with the water 4. The through aperture 54 may also be equipped with a filtering grid in order to retain the larger scale particles in the cavity 50 of the cover 5 and thus be able to establish more precisely the state of scaling. 4. After this emptying operation, the user can screw the cap 43 on the drain port 42 and manually bring the cover 5 in the closed position, the membrane 61 of the hinge 6 then deforming in a 20 first time by generating a return torque which opposes the displacement of the cover 5 to the closed position. When the cover 5 reaches the intermediate position where the curvature of the membrane 61 is reversed, the return torque generated by the diaphragm 61 changes direction and the cover 5 is then automatically brought into the closed position.
    [0010] An apparatus providing a great ergonomic use is thus obtained, the bistable character of the hinge 6 equipping the cover 5 having the advantage of facilitating the manipulations necessary for the emptying, by automatically bringing the cover 5 in the open position for accompany the flow of the liquid leaving the drain orifice 42, or in the closed position to avoid contact with the cap 43. Finally, the apparatus thus produced has the advantage of having a cap 5 which is captive, whose hinge 6 is of high mechanical strength and 3035667 which is directly integrated in the molding with a constituent element of the housing so that the operations necessary for the assembly of the apparatus are reduced. Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications remain 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. In an embodiment variant not shown, the cover may be devoid of an orifice for the flow of the liquid and include only a form of spout 10 edge of the cache.
