Description
- This invention concerns a suction cleaning device as set forth in the main claim.
- The invention refers particularly to cleaning devices comprising a suction assembly associated with an accumulation tank, inside which the dirt sucked in is deposited, able to be connected to pick-up accessories of various types, such as tubes, lances, brushes, or similar.
- The cleaning device according to the invention is advantageously, but not exclusively, of the liquid bath type, that is, provided with an accumulation tank containing a liquid, generally water, able to retain the dirt sucked in.
- The state of the art includes cleaning devices comprising a suction assembly associated with an accumulation tank inside which the dirt picked up is deposited.
- The suction assembly, which may be associated with pick-up accessories of various types, normally comprises an electric motor able to make a fan rotate, the fan being able to generate the suction depression of the cleaning device.
- One of the main disadvantages of such devices is that it is necessary to periodically remove the dirt from the accumulation tank, since to carry out this operation it is necessary to dis-associate the latter from the suction assembly.
- This normally involves manipulating and removing various pieces and/or attachment or clamping elements of the cleaning device, which is a long and complex procedure which may lead to the user getting dirty.
- This disadvantage is even more considerable in the case of cleaning devices of the liquid bath type in which the accumulation tank contains a liquid substance able to retain the dirt sucked in.
- In this type of cleaning device, in fact, the accumulation tank has to be manipulated extremely carefully and cannot be inclined too much, so that the liquid inside, and therefore the dirt, is prevented from leaking.
- It is therefore even more complex and laborious to disassociate the accumulation tank from the suction assembly, and creates considerable inconvenience for the person who has to do it.
- EP-A-0 119 423 discloses a vacuum cleaner wherein a cylindrical suction assembly is arranged in fixed manner on a base support provided with rollers, and wherein a container for the dirt is able to be mounted on the base support in a removable manner. The dirt container is provided with a cylindrical cavity, opening towards the bottom, inside which the suction assembly is housed, with accuracy and in an air-tight manner, when the dirt container is mounted on the base support. This cleaner has the disadvantage that in order to access the suction assembly the dirt container has to be removed first.
- The present Applicant has devised and embodied this invention to overcome these shortcomings and to obtain other advantages.
- The invention is set forth and characterised in the main claim, while the dependent claims describe other characteristics of the invention.

- In a preferential embodiment, the accumulation tank is provided with two lateral chambers, substantially vertical, between which the housing seating for the suction assembly is made.
- According to one characteristic of the invention, the housing seating, in turn, comprises a substantially cylindrical central compartment, opening upwards and two lateral compartments which put the central compartment into communication with the outside from opposite sides.
- The suction assembly is made in a single piece and can be removed from its housing seating simply by being extracted from above.
- In a preferential embodiment, the suction assembly is able to be constrained inside the relative housing seating due to having the same shape.
- In this way, it is easy and quick to dis-associate the suction assembly and the accumulation tank, and then to empty the latter.
- In a preferential embodiment, the suction assembly is solidly associated with a closing cover of the accumulation tank; when the cover is removed the suction assembly is removed from the relative housing seating.
- According to a variant, the cover is provided with gripping means able to allow the cover to be removed more easily.
- According to another variant, the accumulation tank is also provided with relative gripping means, by means of which it can be lifted and manipulated so as to be emptied.
- In a preferential form of embodiment, the suction cleaning device according to the invention is of the liquid bath type.
- In this embodiment, the accumulation tank is able to contain liquids in its lower compartment and the housing seating of the suction assembly is of the air-tight sealed type, so as to prevent any contact between the motor and the liquid contained in the accumulation tank.
- In this case the suction assembly is very easy to extract, which is extremely advantageous because it does not require any movement of the accumulation tank, thus preventing the risk of any leakage of the liquid and of the dirt contained therein.
- In accordance with another variant, the cleaning device according to the invention also has the following characteristics:
- in the lateral chamber of the accumulation tank a conduit to feed the air sucked in is able to be inserted, which is provided with assembly means which allow it to be easily inserted and removed;
- once inserted into the tank, the feed conduit has its lower end arranged below the minimum level of the liquid contained in the tank;

- With reference to Figs. 1-4, a suction cleaning device according to the
invention 10 comprises asuction assembly 11 associated with anaccumulation tank 12, open at the upper part and able to contain the dirt collected. - The
suction assembly 11 is made in a single piece and comprises an outer containing structure, inside which anelectric motor 13 is mounted able to make afan 14 rotate; thefan 14 in this case is mounted coaxial and suitable to generate the suction depression of thecleaning device 10. - The
suction assembly 11 has a substantially cylindrical shape, and is provided with twolateral extensions 16, diametrically opposite each other and provided withapertures 32, by means of which the air taken in is expelled and filtered. - The
suction assembly 11 can be extracted from theaccumulation tank 12 from above, to be selectively dis-associated. - According to one characteristic of the invention, in fact, inside the volume of the
accumulation tank 12, and in a substantially central position, there is ahousing seating 15 inside which thesuction assembly 11 is able to be inserted in a removable manner. - The
housing seating 15 is open at the upper part and is defined by ashell 115 which separates it from theaccumulation tank 12. - In the embodiments shown here, the
housing seating 15 comprises acentral zone 15a inside which themotor 13 and thefan 14 are arranged, and twoslits 15b, open towards the outside, inside which the twolateral extensions 16 are inserted. - The
accumulation tank 12 is associated at the lower part with abase plate 17, by means of which it rests on the floor, and is provided with a handle orgrip 29, pinned at the sides, which allows it to be lifted. - The
accumulation tank 12 comprises a first and a second chamber, respectively 18 and 19, open at the upper part and substantially opposite thehousing seating 15. - The
chambers accumulation tank 12, by aconnection compartment 20 which develops below thehousing seating 15. - The
second chamber 19 is in communication with thesuction assembly 11 and contains afilter 21 inside which is able to prevent the dirt collected inside theaccumulation tank 12 from passing towards thefan 14 and themotor 13. - According to a variant which is not shown here, the communication zone, or
connection compartment 20, can be made on one side of theaccumulation tank 12. - The
accumulation tank 12 is able to be closed at the upper part by means of acover 22 which is solid with thesuction assembly 11 and which can be clamped in the closed position. - In a first embodiment, the
cover 22 and theaccumulation tank 12 are constrained together in a snug-fit connection. - According to a variant, they are constrained together by rapid attachment/detachment means.
- Two
caps cover 22; they communicate with each other and are raised with respect to thecover 22 itself, able to couple respectively with thesuction assembly 11 and thefilter 21. - The
cover 22 is also provided with a handle orgrip 28 and anattachment socket 25, which communicates with thefirst chamber 18; the accessories 30 for picking up dirt are able to be connected to theattachment socket 25. - In the case shown in Fig. 3, the accessories 30 consist of a
flexible tube 26, able to be attached to theattachment socket 25, and alance 27 connected thereto. - When the
cleaning device 10 is functioning, thefan 14 is made to rotate by themotor 13 and creates a depression inside theaccumulation tank 12, with the air circulating from thefirst chamber 18 towards thesecond chamber 19 through the connection compartment 20 (Fig. 3). - Due to this circulation of air, the dirt is then sucked in through the accessories 30 and deposited inside the
accumulation tank 12, while the air sucked in by thesuction assembly 11, after being filtered by thefilter 21, is made to flow outside through the apertures made on thelateral extensions 16. - To dis-associate the
accumulation tank 12 from thesuction assembly 11 and allow it to be emptied, or to carry out maintenance operations on thecleaning device 10, it is sufficient to release thecover 22 from theaccumulation tank 12 and lift it using thehandle 28, so as to remove thesuction assembly 11 from therelative housing seating 15 from above (Figs. 1 and 2). - When these operations are finished, it is easy to re-assemble the
cleaning device 10 thanks to the fact that thesuction assembly 11 and therelative housing seating 15 are associated by having the same form and also to the fact that thecover 22 and theaccumulation tank 12 are constrained together either by rapid attachment means or by a snug-fit connection. - The
cleaning device 10 according to the invention, due to its structure and conformation, is advantageously used with a liquid bath. - The
accumulation tank 12, in fact, can be filled withwater 31 up to a level below the housing seating 15 (Fig. 3), so that the dirt sucked in, substantially forced to pass through theconnection compartment 20, is deposited on the water and remains held therein. - In this embodiment, the
housing seating 15 of thesuction assembly 11 is of the air-tight seal type, to prevent themotor 13 from being exposed to humidity or splashes of water. - Moreover, in combination with the
filter 21, or to substitute it, separation means of a conventional type are provided, able to separate the air sucked in from the particles of dirt agglomerated with the drops of water. - In accordance with a second form of embodiment (Figs. 5-10), a
conduit 40 is removably inserted into the firstlateral chamber 18 of thetank 12; theconduit 40 can be connected to theflexible tube 26 which feeds the air sucked in. Theupper part 41 of theconduit 40 is provided with anassembly flange 42 which cooperates with a correspondingseating 43 made on the upper part of thetank 12. In this way, theconduit 40 can easily be inserted and removed by the user. - The inner
terminal part 44 of theconduit 40 is arranged below the minimum level l1 of the liquid contained in thetank 12, so that the dirty air sucked in from outside is always in contact with the liquid. - In the lower part of the
connection compartment 20 of thetank 12 there are vertical curved bulkheads 45 (Figs. 7 and 9), able to prevent a wave effect of the liquid contained therein, even when thecleaning device 10 is moved. - In the second
lateral chamber 19 of the tank 12 (Figs. 5 and 6), a verticaltubular element 46 is inserted, provided with afilter panel 47 on the periphery. Inside the tubular element 46 a float 48 is able to slide, automatically closing theoutlet aperture 49 of the air from thetank 12, whenever the liquid contained inside the latter exceeds a set safety level. - The
tubular element 46 is also provided with an upper flange 50 able to be mounted on a correspondingseating 51 of thetank 12, to allow it to be easily inserted and removed by the user. - In this second embodiment the
handle 29 of thetank 12 is arranged inside thehousing seating 15 able to house thesuction assembly 11. To be more exact, twohelical springs 52, arranged on opposite sides, constantly thrust thehandle 29 upwards against two fixed stops 53. - When the device is operative (Fig. 6), with the
suction assembly 11 inserted into thehousing seating 15, thehandle 29 is thrust towards the bottom of thehousing seating 15 by thesuction assembly 11 itself. When, on the contrary, thesuction assembly 11 is removed by the user, thehandle 29 automatically returns upwards, against the fixed stops 53 (Fig. 7), ready to be gripped. - At least one of the two
lateral apertures 32 through which the filtered air exits is provided with attachment teeth 54 (Fig. 10) able to cooperate with a corresponding groove 55 of atubular blower element 56, by means of which the filtered air can be conveyed far from thecleaning device 10. - In correspondence with each of the lateral apertures 32 a container of perfumed substances is able to be inserted, of a conventional type and not shown in the drawings, which is able to perfume the air exiting from the
device 10 through theapertures 32. - The
base plate 17 is provided at the bottom with a pair ofwheels 57 which facilitate the movement of theentire device 10 with respect to the floor. - It is obvious, however, that modifications and/or additions may be made to the
suction cleaning device 10 as described heretofore, but these shall remain within the field and scope of the invention. - For example, the
attachment socket 25 for the accessories 30 may be provided on theaccumulation tank 12 or on theconduit 40 instead of on thecover 22, and thefilter 21 may be associated directly with therelative cap 24. - It is also obvious that, although the invention has been described with reference to two specific examples, a person of skill shall certainly be able to achieve many other equivalent forms, all of which shall come within the field and scope of the invention.
