  • the undesired water supply generates an excessive humidification of the fabric to be ironed, by altering the quality of the ironing process.
  • the auxiliary effect of the steam also in the steam cleaning machines or the steam brushes is heavily invalidated by the presence of water at the liquid state.

Said feeding "A” and return “R” pipes and the electric cable 11 are contained, starting from said attachment flanges 15, 20, within the grip 6, for then exiting coupled to each other and wound by the piping 3.
  • Said return pipe "R” is placed in fluid communication with the second chamber 14 and puts this latter into a fluid communication with the base body 2.
  • the dimension of the openings 5 is calibrated for generating, within the first chamber 13 and the second chamber 14, a predetermined steam counter-pressure (for example in the order of 0.3-0.5 bars) which pushes the condensate through the return pipe "R".
  • a predetermined steam counter-pressure for example in the order of 0.3-0.5 bars

  • the thermally actuated bistable element 23 is preferably a bimetallic strip 23.
  • the automatic valve 21 is advantageously associated with a portion of the return pipe R opposite to the work body 4, and is preferably arranged in the base body 2.
  • the automatic valve 21 is therefore a bimetal valve, which has an external body 22 on which the bimetallic strip 23 is placed, housed within a respective annular seat of the external body 22.
  • the external body 22 includes a cylindrical portion 22a which can be coupled at an end of the return pipe "R", and an enlarged portion 22b on which the bimetallic strip 23 is applied.

  • the automatic valve could be of a different type, for example the apparatus could include a temperature sensor and/or an electronic thermostat and an electromagnetic valve or pump controlled by the thermostat for opening and closing the passage in correspondence with condensate and steam, respectively.
  • the bimetallic strip 23 has the feature of carrying itself in the opening position ( figure 4 ) when into contact with the liquid condensate, then allowing the discharge of the same. On the contrary, the bimetallic strip 23 tends to close itself again ( figure 5 ) when the liquid condensate is discharged and, therefore, when the bimetallic strip 23 directly enters into contact with the steam, avoiding a penalizing undesired exit of the steam, which would further cause a loss of pressure in the apparatus 1.
  • the bimetal valve therefore constitutes an automatic valve 21 capable of opening and closing itself as a function, respectively, of the presence of liquid condensate in the return pipe "R" (and in particular close to the bimetal valve itself) and the absence of liquid condensate in the return pipe "R".
  • the presence of the spongy body 17 allows to hold the liquid condensate therewith, preventing that, following to the movement of the work body 4, condensate drops, if any, can reach the conduits 19 and be then supplied within the steam from the openings 5.
  • this harmful effect is further avoided by the protruding conformation of the conduits 19 within the first chamber 13, which makes the conduits 19 hardly accessible to the liquid condensate existing in the first chamber 13.
  • the combined action of the conduits 19 and the spongy body 17 defines an effective separation of the liquid condensate from the steam within the work body 4, with a consequent supply of the sole steam.
  • the liquid condensate discharged by the bimetal valve can be advantageously recovered within the base body 2, preferably in correspondence with a container for the condensate collection, which can be operably connected, directly or indirectly through a water tank, to the steam source or boiler for vaporize again the collected condensate.
  • the invention is applicable for example to a steam utilizing apparatus, such as a tumble-dryer with a steam cycle.
  • the use portion of the steam 5 can consist of a steam utilization chamber within the work body 4 and the collection portion 14 can consist of a steam collection chamber within the work body 4.
  • the structure of the separation means can be easier, consisting for example by the only first chamber 13 (whose lower portion can form the collection portion 14) and the conduits 19, without the need of a second chamber 14 and the spongy body 17.
  • the present invention attains the proposed aims, overcoming the drawbacks complained in the known art.
  • the apparatus according to the invention allows an effective separation of the condensate from the steam directly within the work body, thus allowing that also by shaking in a remarkable way the work body, a liquid exit from the steam supply openings never occurs.
  • the apparatus is therefore capable of supplying, under any working conditions, steam free of condensate.
  • the work body is very light and easy to handle, being formed by simple and light components.
  • the presence of the automatic (bimetal) valve allows a correct removal of the condensate from the work body, without the risk of a steam escape, with a consequent optimization of the effectiveness of the apparatus.
  • the invention also results of a simple and economic execution.
