Definitions

  • the present invention relates to an ironing appliance having a base provided with a tank for the production of steam under pressure and relates more particularly to an ironing appliance in which the vessel is fitted with a filler hole closed by a removable cap, or plug.
  • Known ironing appliances include a tank for the production of steam under pressure with a filler hole closed by a removable cap that can be screwed into the filler hole.
  • a removable cap that can be screwed into the filler hole.
  • the user does not know where to place the cap when it has been removed from the hole to fill the tank.
  • the cap is thus most frequently placed on the base, with a significant risk of falling, exacerbated by the cylindrical shape of the cap, which tends to cause it to roll. Now, the cap may be damaged during the fall, with possible consequences on the safe use of the appliance.
  • a goal of this invention is to remedy these problems by offering an ironing appliance in which the risks of falling of the cap for closing the filler hole are eliminated.
  • the invention has for its object an ironing appliance including a base with a tank for the production of steam under pressure with a filler hole closed by a removable cap, wherein the appliance has connection means connecting the removable cap to the base when the cap is in an open position permitting access to the filler hole.
  • Such a characteristic allows the cap to be prevented from falling when it is removed from the filler hole.
  • connection means are constituted by an articulated arm connecting the cap to the base.
  • Such an arm has the advantage of ensuring proper and rapid placement of the cap against the filler hole during closing of the cap.
  • the cap is rotatably mounted on the articulated arm.
  • the base has a housing enclosing the tank for production of steam under pressure, the articulated arm being carried by the housing.
  • the removable cap is immobilized facing the filler hole by fastening means allowing the rapid opening and/or closing of the cap by rotating it through less than one turn.
  • Such a characteristic allows a great ergonomics of use of the appliance, particularly during periodic tank filling operations.
  • the cap is connected to the end of a pipe surrounding the filler hole by means of a bayonet type connection.
  • the cap includes a handle projecting radially from the cap.
  • the handle comes to operate a safety switch when the cap is properly closed.
  • Such a safety switch will enhance the safe use of the appliance by preventing operation of the appliance and more particularly heating of the tank when the cap is not properly closed.
  • the appliance includes guiding means raising the cap at the end of its opening travel, when the cap is not retained on the filler hole by the fastening means.
  • the appliance includes a safety body preventing the opening of the cap when the pressure in the tank exceeds a predetermined threshold.
  • FIGS. 1A to 1C are perspective views of a base of an ironing appliance according to a particular embodiment of the invention, the closure cap being shown in different positions in these figures;
  • FIG. 2 is an exploded perspective view of the closure cap coming to face the filler hole of the tank of the appliance of FIGS. 1A to 1C , the housing of the appliance not being shown in this figure;
  • FIG. 3 is another perspective view, partly exploded, of the closure cap of FIG. 2 ;
  • FIG. 4 is a top view of the appliance of FIG. 1C ;
  • FIG. 5 is a cross-sectional view along the line V-V of FIG. 4 ;
  • FIGS. 6 and 7 are cross-sectional views of the base of the appliance along line VI-VI of FIG. 4 , when the tank is respectively at atmospheric pressure and under pressure.
  • FIGS. 1A to 1C show an ironing appliance having a base 1 comprising a housing 10 containing a steam generating tank 2 , visible in FIG. 2 .
  • Tank 2 comprises conventionally heating means for the production of steam under a maximum pressure of about 4.5 bars and a solenoid valve designed to be connected to an iron by a cord, not shown in the figures.
  • Tank 2 is advantageously made of stainless steel material with a thickness of 1.2 mm and presents a filler hole 3 around which is welded or soldered a filler pipe 4 closed by a removable cap, or plug, 5.
  • the appliance includes connection means 6 connecting cap 5 to base 1 when cap 5 is open to allow access to the filler hole 3 .
  • these types of connection means are formed by an articulated arm 6 connecting cap 5 to housing 10 .
  • articulated arm 6 is returned by a return spring 60 , visible in FIG. 2 , into a substantially vertical position illustrated in FIG. 1A , in which arm 6 is immobilized by an end of travel abutment.
  • articulated arm 6 has an elongated body 61 , of substantially rectangular cross section, which is furnished at one end with an articulation axis 62 mounted to pivot at the edge of housing 10 , the other end supporting a circular ring 63 receiving cap 5 .
  • Cap 5 advantageously opens rapidly and is rotatably mounted on arm 6 in a manner to pivot by one-third of a turn between an unlocked position shown in FIG. 1B and a locked position shown in FIG. 1C .
  • Cap 5 has a cover 50 presenting a substantially circular body with a diameter of about 6 cm coming to cover ring 63 , the upper edge of the latter comprising a small diameter forming a shoulder 63 A under which a disc 51 comes to be engaged. Disk 51 pivots inside circular ring 63 and presents a peripheral edge whose upper surface comes close to shoulder 63 A of the circular ring.
  • Disc 63 and cover 50 are made of a polyamide material and are fixed to one another by assembly pieces 52 , carried by disc 51 , which are fitted in tubes 50 A carried by lid 50 .
  • the coupling of cap 5 on filler pipe 4 is provided by a jaw 53 of hardened stainless steel material having a thickness of 2.6 mm, which is disposed between cover 50 and disc 51 .
  • Jaw 53 has two symmetrical claws 53 A traversing two lateral notches 51 A of the disc and coming to engage under ramps 40 formed by a folded edge at the end of filler pipe 4 to form a bayonet type connection, the folded edge having locally two cutouts 41 for the passage of claws 53 A.
  • claws 53 A of the jaw and ramps 40 of the stainless steel tubing material are covered with Teflon or processed by immersion in a bath of tin, then possibly covered with a varnish to promote sliding during opening or closing of cap 5 .
  • Jaw 53 has two oblong holes 53 B in which are inserted two assembly pieces 52 so that the rotation of cover 50 entrains rotation of jaw 53 , oblong holes 53 B allowing a slight rotational deflection of jaw 53 with respect to lid 50 , return springs 54 being provided to bring jaw 53 in abutment against one end of oblong holes 53 B.
  • disc 51 has a central opening 51 B surrounded by a peripheral sleeve into which comes to be inserted central brass core 55 , the upper end of central core 55 being inserted into a central opening 53 C of jaw 53 .
  • Core 55 has a first shoulder 55 A coming to be supported against the edge of central opening 53 C of the jaw and presents a groove 55 B receiving an elastic ring 58 axially blocking jaw 53 on core 55 , core 55 however being able to turn freely relative to jaw 53 .
  • the lower part of core 55 receives a annular joint 56 , which is engaged elastically in a groove defined in its upper part by a second shoulder 55 C, the latter having an external diameter corresponding substantially to the outer diameter of joint 56 .
  • Such a shoulder 55 C allows pressing sealing joint 56 against the edge of filler hole 3 when jaw 53 of the cap is screwed on filler pipe 4 , as is illustrated in FIG. 5 , ramp 40 of the pipe extending helicoidally so that the rotation of jaw 53 is accompanied by an axial translation of core 55 toward filler hole 3 .
  • the free rotation of core 55 relative to jaw 53 has the advantage of applying the joint 56 axially on the edge of hole 3 without entraining the latter in rotation, which permits limiting considerably the wear of joint 56 due to friction.
  • Joint 56 is advantageously made of EPDM (ethylene propylene diene monomer) or silicone and has a minimum height of 4 mm and preferably of the order of 10 mm, so that it can be compressed, when the cap 5 is screwed on 4 filler pipe, to a minimum of 10% of its height and a maximum of 30%, depending on manufacturing tolerances.
  • EPDM ethylene propylene diene monomer
  • silicone silicone
  • Such a characteristic allows to ensure both a good watertightness and a significant lifetime of joint 56 by allowing it to maintain a good elasticity over time.
  • filler pipe 4 is equipped with an opening 42 , or a lateral notch, permitting evacuation of excess water possibly present in the filler pipe.
  • Filler opening 3 advantageously has a diameter of between 20 mm and 40 mm, and preferably of the order of 30 mm, so as to allow a rapid filling or emptying of tank 2 without however excessive force on ramps 40 of the filler pipe as a result of pressure exerted on cap 5 .
  • a diameter of 30 mm for the hole provides for a filling or emptying of 1 liter of water in 6 seconds.
  • cover 50 includes a radially extending handle 57 , the side face of handle 57 coming to operate a safety switch 7 preventing activation of the heating means of tank 2 when cap 5 is not completely closed.
  • This safety switch 7 shown in dotted lines in FIGS. 1A to 1C , is carried by housing 10 and is disposed at the end of travel of the trajectory swept by handle 57 during closing of cap 5 .
  • a signal light 70 is associated with this safety switch 7 so as to alert the user on the state of safety switch 7 and therefore on the correct closure of cap 5 .
  • handle 57 incorporates a pressure indicator formed by a lever 8 pivoting inside the body of the handle 57 about an axis 80 , this lever 8 having a rounded tip 81 coming opposite an opening 57 A formed in the lower wall of handle 57 and an indicator surface 82 moving next to a window 57 B provided in the upper surface of the handle.
  • This lever 8 is intended to cooperate with a safety body 9 , carried by tank 2 , having a finger 90 able to be moved vertically as a function of the pressure in the tank, finger 90 passing through housing 10 at the level of a hole 10 A facing opening 57 A of the handle when the latter is in the closed position illustrated in FIG. 1C .
  • FIG. 6 illustrates the position of safety body 9 when the pressure difference between tank 2 and atmospheric pressure does not exceed 0.02 bar.
  • safety body 9 is then in lowered position in which the end of finger 90 of the safety body is flush with the top surface of housing 10 .
  • Lever 8 in the handle then occupies a first position into which it is moved by gravity. In this position, lever 8 is in abutment against the underside of handle 57 , the rounded end 81 of the lever then being located inside hole 57 A so that a first zone 82 A of indicator surface 82 lies next to window 57 B.
  • this first part 82 A of indicator surface 82 is green in color to indicate that the user can open cap 5 .
  • handle 57 is not blocked against rotation by finger 90 and can be easily turned by the user.
  • finger 90 of the safety body When the pressure difference between tank 2 and atmospheric pressure is greater than 0.02 bar, for example following activation of the heating means, finger 90 of the safety body is moved upwardly as illustrated in FIG. 7 . In this position, finger 90 of the safety body is engaged in hole 57 A of handle 57 , preventing any rotational movement of cap 5 .
  • the insertion of finger 90 through hole 57 A is accompanied by pivoting of lever 8 into a position in which a second part 82 B of indicator surface 82 is next to window 57 B, this second part 82 B advantageously being red in color in order to alert the user of the impossibility of opening cap 5 because of excessive steam pressure prevailing in tank 2 .
  • the user is then obliged to wait until the pressure in tank 2 falls below the threshold of 0.02 bar to open the cap.
  • This drop in pressure occurs naturally when the temperature of the tank 2 drops and can be accelerated by the user by actuating, for example, the steam delivery trigger with which the steam iron is equipped.
  • a ramp 10 B disposed at the end of the rotational opening travel of cap 5 .
  • This ramp 10 B presents a height of about 3 mm, which assures the lifting and pivoting of handle 57 and thus of joint 56 during the rotation of cap 5 for its opening, creating exposure of tank 2 to the air.
  • Such an appliance has the advantage of providing a great ergonomics in use in holding the cap when the latter is removed from the filler hole, thus avoiding any dropping of the cap.
  • the articulated arm has the advantage of ensuring proper placement of the cap against the filler pipe during closing of the cap so that the risks of improper engagement of the cap are eliminated. This last characteristic is particularly important in the case of a mating of the cap on the pipe by a screw turn, because it eliminates the risk of deterioration of the threads and blocking of the cap, which could happen if the cap is not properly engaged.
  • the core is hollow and has a central cavity closed by a wall ensuring the watertightness of the cap.
  • the central cavity may receive, in a manner known per se, a safety valve subjected to the pressure in the tank through a hole formed in the wall.
  • the safety valve could for example be arranged to open beyond a pressure of 6 bars so as to prevent any defect in regulation of the heating means of the tank.
  • the coupling of the cap on the filler pipe may be effected conventionally by screwing the cap in several turns instead of a bayonet connection.
