Definitions

  • This invention has for object an improved lance particularly for steam delivery, and apparatus for the cleaning of surfaces so obtained.
  • the innovation finds particular even if not exclusive application in the field of the electric domestic appliances as safety-device for operating the controlled delivery of a steam jet.
  • steam appliances that is those apparatuses, traditionally connectable to the mains, that being provided of a boiler delivery steam on control, to have it delivered on the surfaces by means of suitable extension piping or alternatively allowing the use of other accessories.
  • steam appliances that is those apparatuses, traditionally connectable to the mains, that being provided of a boiler delivery steam on control, to have it delivered on the surfaces by means of suitable extension piping or alternatively allowing the use of other accessories.
  • the attention of the field operators is focused on such apparatuses, quickening a daily search for solutions which are innovative and improving if compared to the ones already existing with the purpose of making the product suitable to the always increasing needs of the user.
  • a traditional electric domestic appliance for example, can consist essentially of a steam producing boiler, enclosed on the inside of a covering body, aesthetically pleasant, that contains also its operation controlling electric part, preferably provided with underlying means for facilitating the movement on the ground of the apparatus.
  • Said boiler on the outside, is additionally provided with a mouth for topping up the liquid, which projecting from said body provides a large closing screw plug.
  • Always on the surface of the body may be provided some pilot lights that, whether or not lighted, allow to check the condition of the boiler, and if necessary some ON/OFF controls for the activation.
  • said body provides a quick connector for allowing the connection of a flexible hose, of the known type, which ends with a pistol provided with handle, generally anatomical, which in its turn supports the delivery lance, practically made of a stiff extension tube having, on its end, a suitably shaped delivery drawhole.
  • a traditional control device may consist of a ON/OFF switch of the electric type, placed at the top along the pistol body. Said switch, is electrically connected to the boiler and specifically to a valve, by means of the wire embedded in the same flexible hose that lets the steam in.
  • the latter tube provides, respect to the opposite end of the engagement with the pistol and of the delivery drawhole, a plug which being enclosed into a box for the quick connection of the flexible hose to the apparatus, fits into a corresponding socket, provided on the body.
  • a first solution to the above-mentioned problems consisted in providing the use of low tension current regarding only the activation of the controls existing on the handle.
  • the aim of this invention is also that to obviate the above-mentioned drawbacks.
  • Figure 1 represents a sectional view of a half-shell of a handle for the delivery of steam jets, whose push button is in a static condition.
  • Figure 2. is again a section view of the same handle as in previous Figure, but whose push button is shown in a condition different from the previous one, in this case of a dynamical type.
  • Figure 3 is a total view referring to the connection of a flexible hose to the corresponding capillary coming from the handle, with the respective apparatus on the ground provided with boiler for steam generation.
  • Figure 4. represents in particular the connection of a capillary coming from the handle, with a pressure switch associated in the steam generating apparatus.
  • Figure 5. represents a view, partially in section, of the same connection as in Figure 4.
  • Figure 6. is an exploded view of the components that make up the connection of a connecting capillary coming from the handle, as in Figures 4. and 5., with the respective steam generating apparatus.
  • FIG. 7 represents a front view of the male connection, associated on the capillary end, on the part opposite to the handle.
  • an apparatus (A) for generating steam is provided essentially of a boiler (1) traditionally supplied by the mains, and of relative operating controls, placed on the body.
  • a valve (2) that regulates the steam inflow in the following flexible hose (3), which leads to a suitable pistol (4) downwards provided also of at least one delivery drawhole.
  • Typical characteristic of the flexible hose (3) is that of allowing the connection and viceversa to the apparatus (1) placed on the ground, whenever needed, by means of an end (3') provided with suitable quick connection means.
  • the pistol (4) is of the type consisting of two half-shells, of which at least one provides the making of a seat (6), essentially made up of retaining walls, and on whose inside is housed a membrane (7) preferably of the pneumatic type but not excluding the hydraulic alternative. Said membrane (7), rests firmly on a base surface (6'), and preferably consists of a hemispherical bubble in PVC, to which is connected the opposite end (5') of the capillary (5). Above the seat (6) and the corresponding membrane (7) is obtained in said pistol (4), an opening (10), able to house a push button (8) of the type supported by a lever arm (8') having as fulcrum a nearby pin (9).
  • the body, in the hypothesis a parallelepiped, of the push button (8) is rather large to provide on the upper part (8") a suitable surface on which to exert a slight pressure with the fingers.
  • a slider (11), with the knurled surface is provided on the upper part of the push button (8), for allowing a slide (12) to make a longitudinal movement, and in such a case to come out from the push button (8), where is obtained the corresponding seat.
  • Such condition appears particularly advantageous, wherever there is a need for a constant operation of the push button (8), in place of the traditional impulses. More in detail, in Figure 2.
  • the push button (8) determines a displacement of the fluid from this latter towards the capillary (5).
  • a pressure switch (14) is connected, by means of suitable quick connector, a pressure switch (14), said pressure switch being enclosed in the apparatus (1) that provides for the steam generation.
  • the pressure switch (14), measuring a pressure variation emits a signal to the valve (2) that regulates the emission of the steam flow from the boiler towards the flexible hose (3), viceversa said valve (2), not receiving any signal remains in closed position.
  • a particularity consists of the end (3') for the quick and complete connection, to the apparatus (1), both of the flexible hose (3) and of the capillary (5). More in detail said end (3') provides at least one leading end (15), made up of an essentially cylindrical body, which on one side (15') engages the end (5") of the capillary (5), on the other includes monolithically a male connection (16), suitable to be inserted on the inside of a reduction element (17) housed by joint coaxially to a cylindrical seat (14') obtained in the pressure switch (14).
  • the reduction element (17) thus being interposed, consists mainly of a cylindrical body, internally provided of a sealing gasket (17'), from which project two opposite tongues (17"), elastically yielding, and each provided on the end of a corresponding hook.
  • These tongues in joining the leading end (15) of the capillary (5), to the end (14') of the pressure switch (14), yield, in correspondence of openings (18'), respectively two diametrically opposite ones, obtained peripherally respect to a disc (18) integral with the male connection (16), until they pass over these same ones, therefore, once released, tending to diverge and therefore to be fixed.
