Abstract
Description
- This invention relates to a steam cleaning apparatus.
- As is known, 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.
- Another problem encountered with such solutions is that the boiler contains a pressurized liquid which, despite the presence of thermostats or maximum pressure relief valves, can create a source of serious danger owing to faulty operations.
- Another drawback of the above solutions is then that the apparatus is practically composed of two entities(i.e. the boiler and the delivery outlet) which.are separate from each other and connected by a flexible hose.
- Another drawback of the above solutions is due to the large thermal losses in the steam flow through the flexible hose connecting the boiler to the delivery outlet.
- Also a drawback of known solutions is that they are in general scarcely handy, do not permit to be differently located, and have large weights because of the particular construction of the boiler which must be capable of withstanding the pressures which are generated on its interior.
- 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.
- Within the above-specified aim it is a particular object of the invention to provide a cleaning apparatus wherein the starting time, i.e. the time required to bring the apparatus in the work condition, is extremely short and wherein it is not necessary to heat simultaneously the entire mass of water present in the tank.
- Also an object of this invention is to provide a clean- ing 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 above-mentioned aim, and the outlined and other objects to become apparent hereinafter, are achieved by a steam cleaning apparatus, according to the appended
claim 1. - The features and advantages of the invention will be clearly apparent from the description of a preferred, though not exclusive, embodiment of a steam cleaning apparatus, as shown by way of illustration and not of limitation in the accompanying drawings where:
- Figure 1 shows schematically the cleaning apparatus, according to the invention, in a possible utilization conformation thereof;
- Figure 2 shows the apparatus in a partly sectioned and exploded view;
- Figure 3 shows the apparatus, partly in section, in a possible position of utilization thereof;
- Figure shows the apparatus in a different utilization position partly in section to point out the position taken by the dipper in the water tank;
- Figures 5, 6, 7 and 8 show different conformations of delivery outlets;
- Figure 9 shows the wiring diagram of the apparatus;
- Figure 10 shows the apparatus with another exterior conformation substantially in the shape of a gun.
- With reference to the cited figures, the steam cleaning apparatus, according to the invention, comprises a body, generally designated at 1, which has handgrip means consisting of a gripping
member 2 and ahandle element 3, the latter being defined in a middle portion of the body itself. - To the gripping
member 2 there is connected anelectric cable 4, having aplug 5 and possibly provided with aswitch 6. The cited electric cable is further connected to apushbutton 7 for controlling the electric pump, preferably arranged in the grippingmember 2 and advantageously flanked by a'lightindicator 8. - The
gripping member 2 is advantageously provided with aring 9 for suspending the apparatus while thebody 1 defines two cable take-up hooks - The
body 1 defines atank 15, at which thegripping handle 3 is formed, said tank having a filler fitting 16 over which acap 17 provided with asmall vent valve 18 can be fitted. - The
tank 15 accommodates adip tube 20 which is connected to pumping means consisting of anelectric pump 21 driven by thepushbutton 7. - The
dip tube 20 is of the flexible type, and at its free end is provided with aweighing body 22 thereby the free end of thedip tube 20 is at all times submerged in the water irrespective of the position taken by thebody 1 during the apparatus utilization. - The
electric pump 21 is supported on aflange 25 through a threadedring nut 26 engaging with ajoint 27 for connection to thedip 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 de-fines a cylindrical chamber in the walls whereof there is inserted an embeddedresistance 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 theelectric 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 adelivery nozzle 35 attached to the generator 31 through amounting flange 36 which defines a coupling tang 37 for interchangeable application of outlets delivering the steam generated in the flash boiler chamber. - The 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 withbristles 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 then shows a gun-
shaped apparatus 50 which, with a reduced bulk, includes the elements describ- ed above. - The operation of the apparatus is quite simple, as is brought out by the wiring diagram of Figure 9, showing the
pushbutton 7 as interconnected between the leads defining theelectric cable 4 provided with theswitch 6; thepushbutton 7 controls the operation of theelectric pump 21, whereas theelectric resistance 32, in parallel with thelight indicator 8, is controlled by thethermostat 33. - In the practical utilization, it occurs that, after filling the
tank 15 with cold water and applying the filler fitting provided for the particular utilization of the apparatus, it will be sufficient to wait for the flash boiler chamber of the steam generator to reach the sought temperature; reaching the desired thermal level is displayed through thelight indicator 8, which goes off on thethermostat 33 opening the contact. - Once the desired thermal level is reached 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 theelectric punp 21, thus caus- ing injection, through thefitting 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.
- Furthermore thermal losses and waste are minimized, because the steam is generated in the close vicinity of the delivery outlet.
- The invention herein is susceptible to many modifications and changes within the scope of the inventive concept.
- Furthermore, all the details may be replaced with other technically equivalent elements.
- In practicing the invention the materials used, so long as compatible with the specific use, as well as the dimensions and contingent shapes may be any ones according to necessity.
