Definitions

  • the present invention relates to an improved electric steam iron.
  • Known steam irons include a heating soleplate comprising an electrical heating resistor, a water tank, a vaporization chamber, and a device for supplying water to the vaporization chamber.
  • This assembly is capped by a protective bodywork in which is generally incorporated a handle for gripping the iron.
  • This cartridge is filled with an ion exchange resin which has the effect of removing from the water the elements such as limestone which are responsible for the scaling of the vaporization chamber and the steam outlet openings made. in the soleplate.
  • this cartridge poses a sealing problem between the reservoir and the conduit communicating with the device for supplying the vaporization chamber.
  • the object of the present invention is to provide improvements to the steam iron described in the aforementioned French patent application.
  • the invention thus relates to an electric steam iron comprising a heating soleplate, a vaporization chamber, a water tank, a device for supplying water to the vaporization chamber, a demineralizing cartridge placed in the circuit of water which connects the tank to the vaporization chamber, the assembly being capped by a protective bodywork.
  • this iron is characterized in that the demineralizing cartridge is removably disposed between a primary tank of raw water and a secondary tank of demineralized water which communicates with the water supply device, the cartridge communicating with the primary reservoir and the secondary reservoir by means of valves preventing the flow of water, when this cartridge is removed from the iron.
  • the cartridge physically separates two reservoirs which contain one of raw water and the other of demineralized water.
  • the valves allow the cartridge to be removed for replacement by a new cartridge, without water flowing from one of the tanks.
  • the rear part of the body of the iron is extended beyond the rear edge of the sole, the demineralizing cartridge being housed in said rear part, and located at a sufficient distance from the sole to avoid any heating of this cartridge.
  • the ion exchange resin contained in the demineralizing cartridge does not withstand a very high temperature and in particular not the heating caused by the heating soleplate and the wall of the vaporization chamber.
  • the cartridge in a rear part of the iron situated beyond the rear edge of the soleplate, it is sufficiently distant from the latter to avoid any heating which is likely to render the resin inactive.
  • the demineralizing cartridge is arranged so removable in a housing which is connected to the water tank.
  • the water tank extends substantially parallel to and at a certain distance above the heating soleplate, the bottom of the cartridge housing being located substantially in the bottom extension of the tank.
  • the arrangement of the cartridge does not affect the overall height of the iron.
  • the upper wall of the cartridge housing is adjacent to the interior of the water tank.
  • This wall of the housing thus forms part of the wall of the tank, so that the housing is integrated into the tank.
  • this wall allows, by heat exchange with the water in the tank, to keep the resin at low temperature.
  • said upper wall is inclined towards the front of the iron, said upper wall of the housing being connected to the bottom of the water tank by an inclined panel, the rear edge of the inclined panel being connected to the upper wall of the housing by a transverse partition forming with this wall a receptacle constituting a water reserve.
  • This inclined pan allows a supply of water to the cartridge by the "waves" of water formed during the back and forth movement of the iron.
  • the waves thus formed flow into the receptacle forming a reserve which communicates with the inlet of the cartridge.
  • the electric steam iron comprises a heating sole 1 containing an electrical resistance 2, a vaporization chamber 3 closed by a metal wall 4, a water tank 5, a device 6 d water supply "drop by drop” to the vaporization chamber 3, and a demineralizing cartridge 7 (see FIGS. 2, 3 and 4) placed in the water circuit which connects the reservoir 5 to the vaporization chamber 3.
  • the water tank 5 extends horizontally between the front and the rear of the iron, above the vaporization chamber 3.
  • the latter is separated from the upper wall of the vaporization chamber by a wall 9 in relatively thick plastic which thermally insulates the water tank 5 from the hot lower part of the iron.
  • the front part of the iron has a flap 10 which releases an opening 11 allowing water (generally tap water) to be introduced into the tank 5.
  • water generally tap water
  • the demineralizing cartridge 7 is removably disposed in a housing 12 located between a primary tank of raw water 5 and a secondary tank of demineralized water 25, which communicates with the water supply device 6. This cartridge 7 communicates with the primary reservoir 5 and the secondary reservoir 25 by means of valves 27a, 27b preventing the flow of water, when this cartridge is removed from the iron.
  • the secondary tank 25 is disposed inside the primary tank 5.
  • the secondary tank 25 consists of two capacities 25c and 25d located respectively at the outlet of the cartridge 7 and around the device. supply 6 to the vaporization chamber.
  • the volume of the secondary reservoir 25 makes it possible to supply the supply device 6 of the vaporization chamber when the latter is open at its maximum flow rate, for at least 30 seconds.
  • each of the reservoirs 5 and 25 has means for venting in order to prevent one or more depressions from being created during the flow towards the vaporization chamber.
  • One of these means consists of a tube 26a placed in the environment close to the supply device 6 of the vaporization chamber.
  • the secondary tank retaining valve 27 can be omitted in order to reduce the pressure drop towards the capacity 25, if it is provided, on the instructions for use, that the user will have to leave the iron flat on her sole. This position allows only little water to escape, taking into account the shape and the levels of the two capacities constituting the secondary tank 25.
  • the demineralizing cartridge 7 is removably placed in the housing 12 which is itself integrated into the rear part of the water tank 5.
  • FIG. 1 it can be seen in FIG. 1 that the bottom 13 of the housing 12 of the cartridge 7 is situated substantially at the same level as the bottom 5a of the reservoir 5.
  • the upper wall 14 of the housing 12 of the cartridge 7 is adjacent to the interior of the water tank 5.
  • this upper wall 14 is inclined towards the front of the iron and is connected to the bottom 5a of the water tank by an inclined panel 15.
  • the rear edge 15a or top of this inclined panel 15 is connected to the upper wall 14 of the housing 12 by a transverse partition 16 forming with this wall 14 a receptacle 17 constituting a water reserve.
  • the housing 12 of the cartridge 7 is molded in one piece with the bottom 5a of the reservoir 5.
  • this figure shows that the inclined face 15 extends over only part of the width of the water tank and its edge has a vertical border 18.
  • the housing 12 of the cartridge 7 has on its face opposite to its inlet face 19 which opens outwards, an inlet opening 20a and an outlet opening 20b connected so removable to an inlet nozzle 21a and water outlet 21b of the cartridge 7 (see Figure 4).
  • This cartridge 7 has a central partition 22. At the rear of the end pieces 21a and 21b extends a filtration grid 24 which retains the resin particles 23.
  • the outlet opening 20b of the housing 12 is connected to the water supply device 6 of the vaporization chamber 3 through the conduit 25 which extends inside the water tank 5.
  • the water inlet opening 20a in the cartridge 7 opens into a compartment 26 which is separated from the outlet opening 20b by a partition 27.
  • This compartment 26 is supplied with the water contained in the receptacle 17 forming a reserve and is supplied directly by the water from the reservoir 5 proper only when the iron is in the vertical position, as will be explained in more detail below.
  • Figure 5 shows on the other hand that a part 25a of the conduit 25 is molded in one piece with the bottom 5a of the tank.
  • the other part which covers the part 25a of the duct is designated by the reference 25b in FIG. 5.
  • This part 25a also comprises at its end opposite to the outlet 20b of the housing 12, a vertical duct 26a for venting free.
  • the upper part 5b of the tank is shown, which assembles on its part 5a forming the bottom of the tank 5.
  • the reservoir further comprises, opposite the inlet 21a and outlet 21b of the cartridge 7, valves 27a, 27b each urged by a spring 28 tending to push the cartridge 7 outwards.
  • These valves 27a, 27b are kept open by contact with stops 29 formed at the ends 21a and 21b of the cartridge when the latter is engaged in the housing 17.
  • These valves 27a, 27b close the inlet 20a and outlet 20b of the housing, by the action of the springs 28 which push these valves onto flexible seals 30 engaged on the end pieces 21a, 21b when the cartridge 7 is removed from the housing 12.
  • means are provided for locking and unlocking the cartridge relative to the housing 12. These means cooperate by snap-fastening to ensure locking and include a member accessible to the user for controlling the unlocking.
  • FIG. 6 for the sake of clarity, the different parts of the water supply circuit have been placed end to end.
  • the level N of the water contained in the tank 5 is lower than the top S of the ramp 15 located between the bottom 5a of the tank 5 and the receptacle 17 which communicates with the cartridge 7.
  • the movement of the iron When ironing, the movement of the iron generates waves in the water contained in the tank 5 such that the water can rise on the inclined face 15 and pour successively into the receptacle 17 and maintain therein a substantially constant water level.
  • the water from the reservoir 5 also fills the receptacle 17, the cartridge 7 and the conduit 26.
  • the receptacle 17 forming a reserve of water is filled with water, so that the iron is ready to operate.
  • the outer wall of the cartridge 7 is preferably made of transparent plastic in order to be able to examine the change in color of the product located inside, which allows the user to assess whether it is necessary to replace the cartridge.
  • the volume of the primary reservoir 5 is 220 cm3. That of the secondary tank is 7 cm3, which allows, in the event that the cartridge is unexpectedly blocked, to ensure 30 seconds of steam production, the maximum flow rate of this iron being 15g of steam per minute.
  • the volume of the secondary tank can be increased (in particular by increasing the section of the conduit 25) but without practical consequence, since the flow of vapor is not essentially dependent on the flow of water, but on the electrical power of the soleplate.
