Definitions

  • This patent relates to a steam cleaner for domestic use.
  • Domestic appliances consisting of a base, generally mounted on wheels, in which there are positioned a water container, a pump and a small steam generator located downstream of the pump to feed a movable terminal connected to the base by a hose.
  • the terminal comprises a delivery structure from which there emerges a small quantity of steam, used either directly or in combination with a series of accessories.
  • Said structure is made to slide over the surfaces to be cleaned, these being subjected to the emollient action of the steam and possibly to the mechanical action of accessories.
  • the object of the invention is to provide a very small-dimension domestic cleaner which can be manoeuvred with one hand and contains all the means for its operation so as not to need a separate base, and requiring for its operation only an electrical connection cable.
  • a cleaner comprising the features of claim 1 and preferably having within a single casing, a small water container having a capacity of the order of 200-600 g, a pump having a capacity of 20-50 cm 3 /minute, a known boiler fed by said pump and consisting of a housing carrying in its wall an electrical resistance element of 800-2200 watt power, and a delivery nozzle positioned in proximity to and as exit from said boiler, and having a hole of between 1 and 2 mm diameter.
  • the casing contains the necessary control and safety means such as thermostats, and operating means such as switches.
  • the casing is preferably of gun shape or a shape equivalent thereto such as to comprise means for comfortably gripping the appliance.
  • the casing dimensions may be similar to those of a normal hairdryer so that the appliance can be easily operated in proximity to gaps, or inside small spaces such as domestic cooker ovens.
  • FR-A-1561817 discloses a steam cleaner having water reservoir, pump and electrically-heated steam boiler in a portable housing as do EP-A-0 586 762 and WO-A-94 24920, which are state of the art under Art. 54(3).
  • Figure 1 shows an arrangement of the operational parts contained within a gun-shaped casing.
  • Figure 2 is a view in the direction II of Figure 1.
  • Figure 3 is a section on the line III-III of Figure 1.
  • Figure 4 shows the electrical schematic of the appliance.
  • Said figures show a cast aluminium boiler 1 having embedded in its wall a U-bent resistance element 2 of total length 300 mm and power 1500 W, its ends being connected to the electrical power line via a main switch 4 and a maximum-temperature thermostat 42.
  • the boiler comprises at one end an exit duct 5 in which a nozzle 6 is directly mounted.
  • the boiler At its opposite end the boiler comprises an entry duct 7 connected by an elastomer tube 8 to a pump 9.
  • the pump 9 of commercially available type, has a capacity of 50 cm 3 /min.
  • the block 11 extends to the outside of the casing 13 as a cylindrical stem 18 provided with a seat and respective annular gasket 14, and with an an annular projection 15.
  • the container comprises a seat 17 to be mounted on the stem 18 and to remain locked thereon, a hole 19 being provided at the base of the seat in a position corresponding with the duct 10.
  • the container 16 At its opposite end the container 16 comprises a similar cylindrical seat 20 with its wall provided with a hole 21.
  • the axis of the cylindrical seat 20 is substantially perpendicular to the axis of the cylindrical seat 17.
  • the cylindrical base of a profiled vessel 24 of about 360 cm 3 capacity is inserted into the seat 20 and sealed therein by virtue of the annular gasket 22.
  • This vessel has a half-moon cross-section, as shown in Figure 3, and extends upperly to embrace the end of the casing 13.
  • the upper wall of the vessel 24 is semi-cylindrical of horizontal axis and comprises two grooves 25 to be mounted on corresponding projections 26 on the casing (see Figure 2).
  • the grooves 25 are parallel to the axis of the stem 18 so that the block formed by the container 16 and vessel 24 can be withdrawn and separated from the casing 13.
  • This latter is composed of two half-casings held together by screws, not shown.
  • the casing 13 is of gun shape, its handgrip 131 containing the block 11 and the pump 9.
  • the block formed by the container 16 and vessel 24 acts as a hand protector.
  • a flow regulator 30 can be provided between the pump and the boiler 1.
  • An insulation covering 31 is preferably provided about the boiler 1, and a gasket 32 is provided between the nozzle 6 and the casing.
  • said nozzle 6 is positioned at the end of a tube 60 on which a sleeve 61 comprising at least one small radial hole 62 is slidingly mounted.
  • the sleeve 61 can assume the two operating positions shown respectively by full lines and by dashed and dotted lines in Figure 1.
  • the minimum-temperature thermostat 41 closes the circuit and the lamp 3 lights to inform the operator that the appliance is ready.
  • the minimum-temperature thermostat 41 allows power to reach the trigger switch 29 which, when operated by the operator, powers the pump 9 for the time during which it is pressed.
  • the sleeve 61 can be arranged in the two aforespecified positions. In the first position said at least one hole 62 is closed because it is covered by the tube 60, and the nozzle emits a jet of steam as generated by the boiler.
  • said at least one hole 62 is open by being downstream of the nozzle, so that ambient air is drawn through said hole to mix with the steam and cause its rapid condensation, so increasing its emollient power.
  • the pump can be positioned in line with the boiler, and the vessel can be provided in the handle.
  • the boiler can be positioned in the hand protector, instead of the container 16 and vessel 24.
