Abstract
Description
- This patent relates to a steam cleaner for domestic use.
- Domestic appliances are known 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.
- Known domestic appliances absorb a power of the order of 1500-2000 W. They have serious operational limits deriving both from their bulk and from the lengthy connection between the boiler and the delivery structure, along which heat is lost and a considerable quantity of the generated steam is condensed. They are substantially of poor manageability and are totally unsuitable for cleaning small spaces such as cooker ovens, and corners, gaps and difficultly reachable surfaces because of the presence of the steam feed hose connected to the wheel-mounted base, which is bulky and difficult to handle.
- In addition as the water capacity of such devices cannot exceed 30-50 cm³/minute depending on the available power, the heat loss along the tube, even if modest, is highly penalizing.
- 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.
- This object is attained according to the invention by a cleaner comprising, 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 cm³/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.
- As will be seen hereinafter the casing dimensions are 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.
- The merits and operational and constructional characteristics of the invention will be more apparent from the detailed description of one embodiment thereof given hereinafter by way of non-limiting example with reference to the figures of the accompanying drawings.
- 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 aU-bent resistance element 2 of total length 300 mm and power 1500 W, its ends being connected to the electrical power line via amain switch 4 and a maximum-temperature thermostat 42. - In this manner, on closing the main switch the resistance element is powered until the boiler reaches maximum temperature.
- The boiler comprises at one end an
exit duct 5 in which anozzle 6 is directly mounted. - 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 cm³/min. - It draws water through the
duct 10 provided within ablock 11 securely fixed to theouter casing 13 by acircumferential groove 12. - The
block 11 extends to the outside of thecasing 13 as acylindrical stem 18 provided with a seat and respective annular gasket 14, and with an an annular projection 15. - It is therefore able to sealedly receive, by snap-fitting, a
container 16 containing a water softening filter of about 70 cm³ capacity. - The container comprises a
seat 17 to be mounted on thestem 18 and to remain locked thereon, ahole 19 being provided at the base of the seat in a position corresponding with theduct 10. - At its opposite end the
container 16 comprises a similarcylindrical seat 20 with its wall provided with a hole 21. - The axis of the
cylindrical seat 20 is substantially perpendicular to the axis of thecylindrical seat 17. - The cylindrical base of a profiled
vessel 24 of about 360 cm³ capacity is inserted into theseat 20 and sealed therein by virtue of theannular 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. - For this purpose the upper wall of the
vessel 24 is semi-cylindrical of horizontal axis and comprises twogrooves 25 to be mounted oncorresponding projections 26 on the casing (see Figure 2). - The
grooves 25 are parallel to the axis of thestem 18 so that the block formed by thecontainer 16 andvessel 24 can be withdrawn and separated from thecasing 13. - This latter is composed of two half-casings held together by screws, not shown.
- The
casing 13 is of gun shape, itshandgrip 131 containing theblock 11 and thepump 9. - It receives the
electric power cable 28 via thecable clamp 27, and comprises at its front aswitch 29 functioning as a trigger for operating thepump 9 of the appliance. - At the top of the
handgrip 131 there is thecylindrical part 132 of the casing, containing theboiler 1, the indicator lamp 3 and themain switch 4. - The block formed by the
container 16 andvessel 24 acts as a hand protector. - A
flow regulator 30 can be provided between the pump and theboiler 1. - An insulation covering 31 is preferably provided about the
boiler 1, and agasket 32 is provided between thenozzle 6 and the casing. - As can be seen in Figure 1, said
nozzle 6 is positioned at the end of atube 60 on which asleeve 61 comprising at least one smallradial 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 operation of the invention is clear from the electrical schematic of Figure 4.
- When the
switch 4 is closed theresistance element 2 is activated but the indicator lamp 3 remains extinguished until the boiler temperature reaches the minimum scheduled operating temperature. - When this temperature is reached, the minimum-
temperature thermostat 41 closes the circuit and the lamp 3 lights to inform the operator that the appliance is ready. - When the minimum operating temperature is reached, the minimum-
temperature thermostat 41 allows power to reach thetrigger switch 29 which, when operated by the operator, powers thepump 9 for the time during which it is pressed. - It is evident that the
pump 9 cannot operate if the boiler has not reached the minimum temperature, ie without enablement by thethermostat 41. - During the use of the invention the
sleeve 61 can be arranged in the two aforespecified positions. In the first position said at least onehole 62 is closed because it is covered by thetube 60, and the nozzle emits a jet of steam as generated by the boiler. - In the second position 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 combination/arrangement of the aforesaid parts can be varied within the gun-shaped casing, without leaving the inventive concept.
- For example the pump can be positioned in line with the boiler, and the vessel can be provided in the handle.
- Likewise the boiler can be positioned in the hand protector, instead of the
container 16 andvessel 24. - These latter can also be formed in a single block.
- All the aforesaid and further modifications lie within the scope of protection of the following claims.
