Definitions

  • This invention relates to a steam cleaning apparatus.
  • apparatuses for steam cleaning generic surfaces such as floors, walls, and so forth, and normally employed for domestic use, are already present on the market, and comprise substantially a boiler which contains water to be heated by an electric resistance heater until steam is produced which, through a flexible hose, is brought to an outlet fitting or device for delivery of the steam over the surfaces to be cleaned.
  • Prior types have, in some embodiments, a solenoid valve which cuts off the steam flow, as controlled from a pushbutton or the like, or may simply have restrict- ed nozzles or other like elements which do not afford control of the steam delivery, which takes place as a continuous flow.
  • the steam production is effected by means of a pressurized boiler into which a certain amount of liquid is introduced which must be fully heated to effect the production of steam, resulting in consequence in a long time for operating the apparatus, with the need for providing heating of the liquid mass throughout, even in those cases where reduced amounts of steam are required.
  • a further drawback of theknown types is then that it is necessary to adopt precautions both in opening_the boiler and in introducing the water into the boiler, because it is necessary, in order to open the boiler, that the temperature and consequently the inside pressure have dropped to adequate levels to prevent steam jets at opening and hazardous thermal surges at the time of introducing the water with the likelihood of steam or hot water jets being ejected outwards.
  • the aim set forth for this invention is indeed that of eliminating the above drawbacks, by providing a steam cleaning apparatus generator which is extremely versatile and handy, and moreover, has no pressurized boiler, with consequent elimination of all the potential hazards.
  • an object of this invention is to provide a clean- i ng apparatus wherein thermal losses and waste are minimised, thereby increasing the efficiency of the apparatus.
  • a further object of this invention is to provide a cleaning apparatus which has an extremely compact and handy conformation as the only constraint is the electric cable and is fully reliable and safe to use.
  • the steam cleaning apparatus comprises a body, generally designated at 1, which has handgrip means consisting of a gripping member 2 and a handle element 3, the latter being defined in a middle portion of the body itself.
  • an electric cable 4 having a plug 5 and possibly provided with a switch 6.
  • the cited electric cable is further connected to a pushbutton 7 for controlling the electric pump, preferably arranged in the gripping member 2 and advantageously flanked by a'light indicator 8.
  • the gripping member 2 is advantageously provided with a ring 9 for suspending the apparatus while the body 1 defines two cable take-up hooks 10 and 11 projecting outwards.
  • the body 1 defines a tank 15, at which the gripping handle 3 is formed, said tank having a filler fitting 16 over which a cap 17 provided with a small vent valve 18 can be fitted.
  • the tank 15 accommodates a dip tube 20 which is connected to pumping means consisting of an electric pump 21 driven by the pushbutton 7.
  • the dip tube 20 is of the flexible type, and at its free end is provided with a weighing body 22 thereby the free end of the dip tube 20 is at all times submerged in the water irrespective of the position taken by the body 1 during the apparatus utilization.
  • the electric pump 21 is supported on a flange 25 through a threaded ring nut 26 engaging with a joint 27 for connection to the dip tube 20.
  • the electric pump 21 delivery is connected, through a thermally insulating fitting 30, to a flash steam generator 31, consisting of a cylindrical or prismatic body which d e-fines a cylindrical chamber in the walls whereof there is inserted an embedded resistance 32 controlled by a thermostat 33 (esemplified in Figure 9 by a switch) which maintains the desired thermal level for the generator 31, such that the water jet admitted through the electric pump 21 is flash steamed.
  • a flash steam generator 31 consisting of a cylindrical or prismatic body which d e-fines a cylindrical chamber in the walls whereof there is inserted an embedded resistance 32 controlled by a thermostat 33 (esemplified in Figure 9 by a switch) which maintains the desired thermal level for the generator 31, such that the water jet admitted through the electric pump 21 is flash steamed.
  • the steam generator 31 is externally insulated by an insulating sleeve 34 and is provided, at the end remote from the water inlet end, with a delivery nozzle 35 attached to the generator 31 through a mounting flange 36 which defines a coupling tang 37 for interchangeable application of outlets delivering the steam generated in the flash boiler chamber.
  • outlets may have varied conformations, according to their specific utilization; in the accompanying drawings some of the possible conformations for such outlets are shown.
  • Figure 5 shows an outlet 40 provided with bristles 41 encircling the steam delivery area, which is particularly suitable for floor cleaning.
  • Figure 6 shows a paddle-like outlet 42 of an extendible type which is advisable for wet cleaning and scraping; and Figure 7 shows a nozzle-like outlet 43 preferably applicable for cleaning hard-to-reach places.
  • Figure 8 furthermore shows a nozzle-like outlet 44 which enables delivery of concentrated steam jets.
  • Figure 10 shows a gun-shaped apparatus 50 which, with a reduced bulk, includes the elements descri b - ed above.
  • the user in order to obtain delivery of the steam, is to merely depress, for a more or less long time period, the pushbutton 7 controlling the electric punp 21, thus caus- i ng injection, through the fitting 30, of a predetermin- ed amount of water which is flash steamed by the flash steam generator 31.
  • the generated steam comes out of the calibrated hole of the nozzle 35 which ensures an appropriate outlet pressure and which is so conformed as not to let out any uncompletely steamed water.
  • the steam so produced is dispensed through the selected outlet over the surface to be cleaned, so as to dissolve the dirt swept by the steam.
  • the apparatus according to the invention has the great advantage of having in a single body both the tank and the steam generator which is connected directly to the delivery outlet, is usable at any positions, that is to clean horizontal orver- tical surfaces, while being always sure that the pump can dip the liquid contained in the tank, since the free end of the dip tube as weighed follows in practice the displacement of the water inside the tank, affording at all times proper operation of the apparatus, thanks also to the particular structure of the steam generator.
  • Another important aspect of the invention consists in the construction as a single compact body including all the component elements, that is the tank and steam generator, avoiding pressurized boilers which, as previously mentioned, are the source of potential hazards.
  • the materials used may be any ones according to necessity.
