Definitions

  • Laundry irons of the so-called steam-spray type are well-known nowadays. In irons of this type water contained in a reservoir is converted by adequate means into steam emerging through holes formed in the lower surface of the ironing or base plate.
  • This device consists of a small pump housed as a rule in the iron handle and capable of drawing water from the reservoir and spray it in the form of a fine atomized jet ahead of the iron.
  • atomizers consist as a rule of a conventional pump body connected to a rigid pipe welded to a spray nozzle.
  • a first -valve is disposed at the lower portion of the pump body for drawing water from the reservoir, and another valve is disposed before the spray nozzle for forcing the water therethrough.
  • the piston consists of a simple cylindrical rod having at one end a seal member or packing engaging the pump body, said rod being adapted to be actuated by means of a push-button emerging from the top of the iron handle.
  • an iron of this general type comprising a device adapted to spray water from a water suction duct communicating with a reservoir housed in the iron and a pump comprising a piston reciprocally movable in a cylinder to form therein a chamber of Variable cubic capacity, a first water-retaining valve opening under suction conditions and preventing the return of water to said reser-voir during the atomization strokes, a second valve opening as the water forced out from the pump is atomized by a nozzle-forming element disposed for example ahead of the iron, said last-named valve preventing the Suction of external air when water is being drawn from the reservoir.
  • a laundry iron constructed according to this invention is remarkable notably 1n that a blind hole is provided in said piston and that a flexible duct of reduced cross-sectional section connects said blind hole in the vicinity of its closed end to said nozzle fixedly mounted in the handle of the iron.
  • the piston and flexible duct are moulded integrally from flexible synthetic material.
  • said cylinder consists of an orifice formed in a fixed portion of the iron handle and connected through a duct to said reservoir; resilient piston-return means are provided and the piston consists of a solid rod formed with the aforesaid blind hole coaxially thereto.
  • the upper portion of the piston is solid.

Of course, all the conventional component elements of a laundry iron are enclosed in the cover 3. Within this cover a reservoir 5 adapted to contain an adequate reserve of water is disposed.
  • This iron is for example of the steam spray type, that is, comprising a suitable watervaporization device (not shown) together with duct means directing the water steam to suitable locations of the underface of the ironing or base plate 2.
  • a water atomizing device 5' constituting the subject matter of the present invention is housed in the handle 4.
  • This device comprises essentially a piston 6 reciprocally and slidably movable in a cylinder 7 consisting of a bore formed in one portion of said handle 4, a push-button 8 for actuating the piston 6 a flexible duct 9 rigid with said piston 6 and connecting a blind hole 6a formed in the piston 6 (FIGURE 2) to an outflaring endv portion 10 having suitably mounted therein the nozzle 11 for spraying water in front of the iron.
  • a Suction duct 12 connects the chamber 13 formed between the piston 6 and cylinder 7 to the water reservoir 5.
  • the piston 6 has formed therein a substantially axial bore 6a; forming a blind hole therein its upper end being spaced from that of piston 6.
  • the bore 9a of duct 9 opens at one end into the -bore 6:2 formed in piston 6 in the vicinity of the closed end of said hole and at its opposite end into a slot or duct 14 communicating in turn With the inner lbore 11a of-*nozzle 11.
  • cylinder 7 constitutes a frusto-conical valve seat -15 en-L gabeable by a ball valve 16 to prevent the water from being forced back through the suction passage 12 into the reservoir 5.
  • the push-button 8 is rigid with the upper end of piston:
  • this button 8 is shown in its fully depressed position in which its peripheral portion 811 abuts against suitable projections 17 of handle 4.
  • This pushbutton 8 is normally urged to its uppermost or inoperative position by a return spring 18 engaging on the one hand a cavity 19 of handle 4 and on the other hand a recess 20 of push-button 8.
  • the duct 12 providing the communication betweencomponent elements suitably assembled with one another for example by gluing or cementing.
  • the nozzle 11 comprises in succession a main cylindrical body 25, a grid 26 through which the atomized water is dispensed, and a socket 27 for mounting this grid on the body 25.
  • a disk 28 mounted in this body and bearing against the grid 26 is a disk 28 engaged by one end of a coil compression spring 29 constantly urging a ball valve 30 against a frusto-concial seat 31 to seal the access to the bore 1111.
  • the body 25 further comprises a flange 32 whereby, when the nozzle 11 is screwed in said portion 10, said nozzle and said portion 10 can be rigidly Secured to the handle 4 about the orifice 33 provided for the passage of the screw-threaded end of the nozzle.
  • the piston 6, p-ipe 9 and portion 10 form an integral moulded unit of suitable relatively flexible synthetic material.
  • the cylinder-forming orifice or bore 7 provided in the handle 4 is suitably bored in this handle or formed by moulding, the handle 4 consis-ting as a rule of a material such as thermosetting resin, for example the one known under the trade name of 'Bakelite.”
  • valve 16 reclosing -to -prevent the ingress of air into the reservoir 5 while valve 30 opens (by overcoming the resistance of spring 29).
