Definitions

  • This invention relates to a steam delivery plate for a steam iron comprising the features pointed out in the precharacterizing part of the claim.
  • a steam iron is for example described in FR-A-2490255.
  • the plates having their holes evenly distributed suit best the ironing of fabrics which are better served by a relatively slow penetration of the steam through their fibers, and no setting of the fibers at a high temperature.
  • plates having their holes concentrated toward the tip are characterized by a relatively high steam outflow velocity and higher fiber setting capability by those plate areas which are not apertured and are, therefore, hotter.
  • an iron in two different modes: a first mode of conventional ironing with the iron resting on and running across a fabric being ironed in order to flatten out any creases by the combined action of heat, steam, and the slight pressure exerted by the operator; a second mode in that of having the fabric fluffed by the sole action of steam.
  • the iron is held in a substantially upright position and moved nearer the fabric so as to direct the steam jets from the steam delivery holes onto it.
  • the plates which have their steam delivery holes gathered more toward the tip suit fabric flutting best because of the steam being delivered at a higher outflow velocity thereby.
  • such irons may not be the preferred ones for primary ironing requirements.
  • the problem underlying this invention is to provide a steam delivery plate for irons which affords an ability to select each time the steam delivery mode, either concentrated or distributed, which suit best the intended purpose.
  • a steam delivery plate 1 for steam irons comprises essentially a base element 2 and a cover 3.
  • the base element 2 has a substantially flat surface forming the ironing sole piece 4.
  • the sole piece 4 has a substantially triangular shape with arcuate oblique sides 4a, 4b, and a straight base 4c.
  • the element 2 is provided, on the opposite side from the sole piece 4, with a capping 6 standing proud of a base plane 7. From the plane 7, there extends a first upright rib 8 of continuous closed loop configuration having two sections 8a,b running at a short distance from the oblique sides 4a,b, and a third section 8c running parallel to the base 4c.
  • a second rib 9 connects to the section 8c which has an inverted "U" configuration; a third rib 10 extends between the sections 8a and 8b.
  • All the ribs 8, 9 and 10 rise from the base plane 7 to the same height level and are formed at their tops with a groove 11 for accommodating a sealing gasket 12 intervening to form a tight fit between the base element 2 and the cover 3.
  • a steam intake and superheating chamber 15 Defined between the ribs 8, 9 and 10 on the base element 2, are a steam intake and superheating chamber 15 and two steam delivery chambers, respectively indicated at 16 and 17.
  • the chamber 16 is located proximate the tip of the plate 1, whilst the chamber 17 extends around the steam intake chamber 15 horseshoe fashion. All of the above chambers, 15, 16 and 17, have their tops closed by the cover 3.
  • a plurality of elevations 20 are provided which are substantially frustoconical in shape and through-penetrated axially by a steam delivery hole 21.
  • the holes 21 extend through the base element 2 and open into the sole piece 4 with a flaring end.
  • the cover 3 has a first, essentially flat surface 23 whose outline mates with the upper edge of the rib 8, and is through-penetrated by four holes 24 intended for fastening said cover to the base element 2 by means of screw fasteners, not shown, threadably engaged in seats 25.
  • a steam intake conduit 28 is arranged to open through the cover 3.
  • the cover 3 On the remote side from the surface 23, the cover 3 has an electric resistance heater 30 embedded therein for heating the plate 1.
  • the resistance heater 30 By locating the resistance heater 30 on the cover 3 rather than the base element of the plate, a more uniform distribution of heat across the sole piece 4 can be obtained with no overheated spots on the latter.
  • a captive screw 31 Secured between the legs of the resistance heater 30 are a captive screw 31 and an abutment peg 32 for mounting a thermostat. Also provided are tangs 33 for anchoring the plate 1 on a body, not shown, of the iron.
  • a channel 35 which is closed at the top by a plate 36, with the interposition of a sealing gasket 37.
  • the channel 35 communicates, via passageways 38, with the steam intake chamber 15, and via two respective passageways 39 and 40, with the two delivery chambers 17 and 16. Said channel 35 forms therefore a steam supply conduit to the two delivery chambers 16 and 17.
  • a seat 41 Formed in the channel 35 at the passageway 39, is a seat 41 adapted to receive a small pillar 42 which extends at right angles from the plate 36.
  • a right-angle bore 43 is formed in that pillar.
  • the free edge of the bore 43 is flared to provide a detent for a ball shutter 44 which is freely movable in the channel 35 between the passageway 40 and the pillar 42.
  • the pillar 42 and ball 44 form a valving means for shutting off the supply of steam to the chamber 17.
  • the ironing appliance of this invention operates as follows.
  • the ball 44 With the plate 1 in a substantially vertical orientation, the ball 44 will abut the pillar 32 and settle on the free edge of the bore 43.
  • the ball 44 By returning the plate 1 to its horizontal orientation, the ball 44 will uncover the bore 43 if the supply of steam to the plate is interrupted. Otherwise, if the supply of steam is maintained, the steam pressure holds the ball 44 engaged with the free edge of the bore 43, and the steam, even with the plate horizontal, will be only supplied through the holes provided in the delivery chamber 16.
  • the plate of this invention affords several advantages over conventional plates. Firstly, the possibility has been significantly enhanced of using an ironing appliance equipped with this plate for steaming operations. Secondly, the sole piece of the plate according to the invention is at a uniformly distributed temperature as achieved by mounting the resistance heater on the cover.
  • this plate can deliver steam which is almost free of any suspended water droplets.
  • the steam delivery plate disclosed hereinabove is equally effective when supplied with steam from a separate boiler, and with water for in situ generation of steam.
