- the present invention also relates to the association of such a vacuum cleaner with a waterproof waste recovery bag intended to be housed in said vacuum cleaner.
- Document GB-A-2 141 635 describes a tank type vacuum cleaner in which a waterproof bag is used positioned on a specific support resting on the bottom of the tank.
- the vacuum produced in the vacuum cleaner makes it possible to aspirate the waste inside said waterproof bag and to expel filtered air using a combination of a motor, a fan and a filtered.
- the structure of the vacuum cleaner is designed so as to provide a free space around the waterproof bag placed in the tank and to produce an air circulation around this waterproof bag. This circulation of air inside the tank makes it possible to balance the pressures prevailing inside and outside the waterproof bag.
- Such vacuum cleaners have a number of drawbacks.
- Document DE-G-90 17 798.3 describes a vacuum cleaner of the tank type in which an interchangeable dust tank is used consisting of a sealed dust bag and a filtering part held together by an annular carrying part, which is provided for lean on an annular rim made in the tank of the appliance.
- the device also includes a pressure tap between the tank, outside the waterproof bag, and the suction pipe of the device, thus establishing a stronger vacuum outside the waterproof bag than inside thereof, the air in this case must pass successively through the additional filtration means and the engine filter.
- the presence of an additional filtration means integral with the dust bag prevents the user from having to handle a full dust bag, the contents of which are in the open air.
- vacuum cleaners have the drawback of an awkward installation of the dust bag in the tank of the appliance.
- the object of the present invention aims to remedy the drawbacks of the prior art and to produce a vacuum cleaner having increased simplicity of use.
- the object of the present invention also aims to achieve a suction assembly whose operation is improved on the one hand, and whose maintenance operations are very limited.
- the object of the present invention also consists in making waterproof bags whose installation in the vacuum cleaner is simplified and whose use provides the user with more cleanliness and less frequent clogging of the filter associated with the system. aspiration.
- the objects assigned to the present invention are achieved by means of a vacuum cleaner comprising a suction system, a compartment placed above a tank intended to contain an impermeable waste recovery bag, a pipe opening into the impermeable bag.
- an additional filtration means intended for use in a vacuum cleaner, characterized in that it consists of at least two layers permeable to the flow of aspirated air.
- a waterproof bag associated with a complementary filtration means in a vacuum cleaner comprising a tank and a filter for sanitizing a flow of aspirated air, consisting of:
- FIG. 1 represents a general sectional view of a vacuum cleaner provided with a waterproof bag according to the invention
- FIG. 2 represents a general diagram in section of the vacuum cleaner and a waterproof bag according to the invention
- - Figure 3 shows an exploded diagram, partial and in section of a vacuum cleaner provided with a waterproof bag according to the invention
- Figure 4 shows an exploded diagram, partial and in section of an alternative embodiment of a vacuum cleaner provided with a waterproof bag according to the invention
- - Figure 5 shows a partial diagram in section of an alternative embodiment of a vacuum cleaner provided with a waterproof bag according to the invention
- FIG. 6 represents a partial diagram in section of another alternative embodiment of a vacuum cleaner provided with a waterproof bag according to the invention
- FIG. 7 represents a perspective view of an example of embodiment of a bag waterproof according to the invention.
- the vacuum cleaner represented for example in FIG. 1 consists of a tank 3 arranged below a compartment 1 containing a suction system 2.
- the tank 3 is intended to receive a waterproof bag 20 for collecting waste.
- a pipe 4 opens into the waterproof bag 20 so as to circulate a flow of aspirated air 12 through the pipe 4, into an internal volume 21 of the waterproof bag 20 and through the suction system 2.
- the latter is composed an electric motor 2c associated with a turbine 2b generating a vacuum inside the vacuum cleaner.
- a filter 2a for expelling filtered air is also provided in the suction system 2.
- FIG. 2 schematically shows the circulation of the different air flows in a simplified manner.
- a flow of aspirated air 12 crosses the pipe 4 to enter the vacuum cleaner and is expelled from the latter by means of the turbine 2b in the form of a filtered air flow 13.
- a flow of cooling air 10, 11 is also used to cool the engine 2c during its operation. It is It is obvious that the end of the pipe 4 situated outside the vacuum cleaner ends in a hose of the flexible type and in a cleaning device of the nozzle or brush type or by other known cleaning means.
- the vacuum cleaner according to the invention also comprises means making it possible to produce a vacuum around the waterproof bag 20 and this inside the tank 3. Such means are essential for obtaining the inflation of the waterproof bag 20, when is placed inside the tank and when the vacuum cleaner is started.
- the waterproof bag 20 is thus associated with a complementary filtration means 25 covering at least partially the internal volume 21 of said waterproof bag 20 and making it possible to create a pressure drop in the flow of aspirated air 12.
- the complementary filtration means 25 also makes it possible to transmit into the tank 3 outside the waterproof bag 20 a vacuum greater than that prevailing inside said waterproof bag 20.
- the vacuum cleaner according to the invention therefore comprises on the way of the suction air flow 12, respectively the pipe 4, the internal volume 21 of the waterproof bag 20, the additional filtration means 25 and the filter 2a associated with the suction system 2.
- the means making it possible to produce a vacuum in the tank 3 and around the waterproof bag 20 is a pressure tap 5 communicating on the one hand with the tank 3 and on the other hand with a space 6 extending at least partially. between the filter 2a and the complementary filtration means 25.
- the space 6 preferably extends in the vicinity of the interface between the compartment 1 and the tank 3. In the embodiment of the vacuum cleaner according to invention shown in Figures 1 and 2, this space 6 extends mainly above and opposite the complementary filtration means 25, which thus achieves a separation, obviously permeable to the flow of aspirated air 12, between the internal volume 21 and the suction system 2.
- the pressure tap 5 is, for example, produced with one or more portions of pipes leading to the space 6 as well as to a free volume 3a extending around the waterproof bag 20.
- the assembly or assembly of the compartment 1 on the tank 3 is carried out in a known manner with known fixing means in order to obtain a perfect seal and therefore a partitioning of the free volume 3a.
- Such a design makes it possible to avoid a random or accidental air intake not compensated by the pressure intake 5.
- Such accidental operation would have the consequence of sucking the waterproof bag 20 towards the complementary filtration means 25 and of obstructing the path of the aspirated air flow 12.
- the complementary filtration means 25 therefore makes it possible, in accordance with the invention, to obtain a pressure differential between the internal volume 21 and the space 6.
- a pressure differential of the order of a few millibars and preferably 10 millibars upstream and downstream of the complementary filtration means 25 thus makes it possible to obtain inflation and / or unfolding of the waterproof bag 20.
- the vacuum cleaner according to the invention is, according to an exemplary embodiment, consisting of compartment 1, of the additional filtration means 25, of the waterproof bag 20 and of the tank 3 thus producing a set of parts that can be easily dismantled relative to the other.
- the compartment 1 is preferably removably and tightly mounted on the tank 3.
- the complementary filtration means 25 is advantageously made with one or more rigid material (s), permeable (s) to the flow of aspirated air 12 and having an opening 26, which is traversed by one end 4a of the pipe 4 when said additional filtration means 25 is put in place in the vacuum cleaner.
- the constituent materials of the complementary filtration means 25 are for example paper or cardboard sheets or any other synthetic material having filtration properties adapted on the one hand to the quality of filtration desired with this complementary filtration means and on the other hand to the desired pressure differential upstream and downstream of the additional filtration means.
- the opening 26 is advantageously provided with elastic tongues closing this same opening 26 when the end 4a is released from the filtration means 25.
- the tank 3 advantageously has in its upper part a peripheral edge 3b extending for example along a horizontal plane towards the inside of said tank 3, so as to produce a support for the compartment 1, when the latter is assembled with the tank 3.
- the waterproof bag 20 has for example a configuration similar to a garbage bag, preferably with dimensions adapted to the size of the vacuum cleaner. Once placed in the tank 3, the waterproof bag 20 rests with its upper end 22 on the peripheral edge 3b. It is the same for the complementary filtration means. The latter, while providing a filter medium, can also be provided with a foldable portion on the opening 26.
- the pressure tap 5 as shown in FIG. 1 is advantageously secured to compartment 1 or else makes an integral part of the latter.
- the peripheral edge 3b is also provided with an orifice 3c which is crossed by a portion of the pressure tap 5 when the compartment 1 is put in place on the tank 3. It is obvious that the pressure tap 5 is made so to protrude out of a support zone 1a presented by the compartment 1 in order to come to bear or rest on the peripheral edge 3b.
- the pressure tap 5 then makes it possible to pierce the upper end 22 of the waterproof bag 20.
- the passage of the pressure tap 5 in the orifice 3c can be done using known means in combination with a seal. for example.
- the end 4a of the pipe 4 also has dimensions adapted to its passage through the opening 26.
- one or more pressure taps 5 are produced directly on the peripheral edge 3b as shown for example in FIG. 2. It is thus up to the user who sets up the waterproof bag 20 in the tank 3, to correctly position and / or pierce the upper end 22 of the bag and possibly the additional filtration means 25, so as to allow the pressure tap 5 to fulfill the function assigned to it.
- the periphery of the complementary filtration means 25 preferably extends above the peripheral edge 3b, and is compressed between said peripheral edge 3b and the support zone of the compartment 1.
- the complementary filtration means 25 consists of at least two layers 30, 31 of nonwoven fibrous synthetic material, as shown in FIG. 3.
- the layer 30 traversed by the flow of aspirated air 12 before the layer 31 is thicker than said layer 31 then passed through.
- the thickness of the layer 30 makes it possible to obtain a volume filtration which has the aim of delaying the clogging of the layer 31 by small particles.
- Layer 31 acts as a dust filtration. It prevents fine particles from passing through the complementary filtration means.
- the complementary filtration means 25 is preferably composed of hydrophobic materials which do not retain water, or even repel it, in the case where the apparatus is used with liquid or wet waste.
- the layer 30 may for example be made of a polyester fiber material, and the layer 31, of a polypropylene microfiber material, either of these materials being capable of being electrically charged.
- the filtration means 25 has an adhesive portion 25a for making the assembly or the connection with the part of the waterproof bag 20 covering the peripheral ring 3c.
- the adhesive portion 25a can be provided on the waterproof bag 20.
- FIG. 3 also shows the pressure tap 5 formed in the peripheral edge 3b, outside the peripheral ring 3c, thus putting in communication , space 6 and free volume 3a.
- the compartment 1 is advantageously attached to the tank 3 in a sealed manner, for example by means of an annular seal 34, as shown in FIG. 3.
- the waterproof bag 20 is provided around its end 22 with a rigid band 22a, by inextensible and / or adhesive example, provided for placement purposes around the rim of the tank.
- the waterproof bag 20 is therefore slid onto a support of the peripheral ring type 3c secured to the peripheral edge 3b.
- the waterproof bag 20 is mounted like a hat or threaded onto the tank 3, using this rigid strip 22a, before being turned over to allow it to be housed inside the tank 3, with the rigid strip 22a remaining fixed on the peripheral ring 3c.
- the filtration means 25 is then attached to the tank 3 and more specifically to the peripheral ring 3c.
- an adhesive portion may be provided on the rigid strip 22a.
- the waterproof bag 20 comprises closure links arranged at its end 22. These links make it possible to maintain the end 22 of the bag 20 around the peripheral ring 3c of the tank 3 , before the installation of the additional filtration means 25. These links also make it possible to easily close the bag 20 after use by enclosing the complementary filtration means 25 inside said bag. The user can thus extract a completely sealed bag from his vacuum cleaner.
- the additional filtration means 25 is fixed to the waterproof bag 20, the latter being intended for use in a vacuum cleaner and associated with the additional filtration means 25 covering the access to the internal volume 21 of said waterproof bag 20 on the one hand and having an opening 26 capable of being traversed by the end 4a of the pipe 4 when the additional filtration means 25 is mounted in the vacuum cleaner.
- the waterproof bag 20 is preferably fixed inseparably to the filtration means 25.
- An embodiment of the waterproof bag 20 according to the invention is thus shown in Figure 7.
- the general configuration of the bag extending inside of the tank 3 is arbitrary and preferably adapts to the general configuration of the tank 3 so as to provide the user with a means for recovering waste from maximum capacity.
- the waterproof bag 20 shown in FIG. 7 takes on a generally cylindrical shape when it is unfolded and has in its upper part the complementary filtration means 25.
- the latter is welded, glued or fixed by any known means to the waterproof bag 20.
- the waterproof bag 20 preferably has a rigid ring 27 ensuring mechanical cohesion with the filtration means 25 complementary on the one hand and facilitating the positioning of the bag in the vacuum cleaner on the other hand.
- the rigid ring 27 is for example used as an interface between the upper end 22 of the waterproof bag 20 and the complementary filtration means 25.
- Such a design makes it possible to facilitate the process of assembling the waterproof bag 20, knowing that the constituent material said waterproof bag 20 is a thin and flexible plastic film.
- the rigid ring 27 may also have one or more holes of dimensions adapted to the passage of the pressure tap 5 and / or to the positioning of the waterproof bag 20 in the tank 3 of the vacuum cleaner by cooperating with positioning pads, not shown. in the figures, distributed over the peripheral edge 3b.
- the rigid ring 27 can also be made of a compressible material thus giving it a sealing role when the compartment 1 is put in place, or fixed on the tank 3. Any material of the cardboard or rubber or plastic type or a combination said materials can be envisaged to produce such a rigid ring 27. The latter nevertheless has sufficient flexibility so as not to hinder the sealing obtained between compartment 1 and tank 3.
- Such an assembly can also be obtained, according to another alternative embodiment of the vacuum cleaner according to the invention, with a tight seal over an entire outer periphery 28 of the rigid ring 27, therefore on the peripheral edge 3b.
- Holes 29 distributed on the same rigid ring 27 but inside this external periphery 28 are then used to communicate with the pressure tap 5 or to be crossed by said pressure tap 5.
- the latter will advantageously be made with a peripheral groove formed in the portion of the support zone 1a of the compartment 1 which comes to bear on the peripheral edge 3b so as to cover at least one of the holes 29. It is obvious that such a peripheral groove not shown in the figures will have to communicate freely with the space 6 or there will be a depression which one wishes to transmit around the waterproof bag 20.
- the vacuum cleaner comprises a deflector 32 arranged on the natural path of the flow of aspirated air 12 between the complementary filtration means 25 and the filter 2a.
- the deflector 32 is preferably provided with studs 32a, which press on the complementary filtration means 25, thus leaving a space between the wall of the deflector 32 facing the filtration means 25 and said filtration means 25.
- This deflector allows to distribute the air flow 12 more evenly over the entire surface of the complementary filtration means 25.
- the deflector 32 is advantageously fixed to the compartment 1, for example at the level of the filter 2a.
- the vacuum cleaner comprises a plate 33 in which is inserted the complementary filtration means 25.
- the plate 33 is advantageously provided with an annular rim 35 and lugs 36 arranged on the internal wall of the upright 37, designed to retain the additional filtration means 25, as well as with a portion of tube 34 intended to extend the end 4b of the pipe 4 provided for insertion into the opening 26 of the filtration means 25.
- the plate 33 is provided with centering means 38 in order to ensure correct positioning on the tank 3.
- FIG. 6 shows the centering means 38 provided for insertion into the orifices provided in the wall of the tank 3 to produce a pressure tap 5, said centering means 38 being themselves traversed by an orifice 38a.
- the user thus benefits from easier positioning of the filtration means 25 complementary thanks in particular to the rigidity provided by the plate 33.
- the plate 33 also allows the user to more easily extract the sealed bag 20 filled.
- the deflector 32 can be fixed to the plate 33.
- the additional filtration means 25 is washable and reusable.
- This means can then consist for example of one or more layers of synthetic material, or a fabric stretched over the plate 33. It is thus possible to have filtration means suitable for the work to be carried out.
- the additional filtration means 25 consist of more than two layers 30, 31, for example that the additional filtration means 25 consist of a very coarse first layer stopping large but light particles such as hair, hair , etc. a second layer ensuring a filtration in thickness of the fine particles and a third layer ensuring the stopping of these particles.
- the present invention is therefore implemented using the complementary filtration means 25 in a vacuum cleaner already provided with a filter 2a associated with the suction system 2 to sanitize the flow of aspirated air 12.
- Such use of the means 25 additional filtration improves the filtration of the air flow sucked 12 and create a vacuum around the waterproof bag 20, waste collector, disposed in the vacuum cleaner.
- a person wants to use a vacuum cleaner in accordance with the invention it suffices for him to have a waterproof bag 20 in the tank 3, to add to the assembly thus formed the additional filtration means 25 possibly inserted in the plate 33, and then close compartment 1 on tank 3. The vacuum cleaner is then ready for use.
- An advantage of a vacuum cleaner according to the present invention lies in the simplicity of use of such a vacuum cleaner. In fact, it suffices to separate the compartment 1 from the tank 3, to put in place the waterproof bag 20 inside the tank 3, to put in place the complementary filtration means 25, which can optionally be inserted in the plate 33, and then close compartment 1 on the tank 3. The vacuum cleaner is thus ready for use.
- An additional advantage of a vacuum cleaner according to the present invention resides in the installation of the waterproof bag 20 in the tank 3.
- the user places the bag 20 in the tank 3 and begins to deploy it against the walls.
- the major drawback of seeing the bag 20 driven against the complementary filtration means 25 by the air flow 12 before it is deployed under the effect of the vacuum created by the air flow 12 passing through the additional filtration means 25 is avoided.
- a considerable advantage of a vacuum cleaner according to the present invention lies in the very low manufacturing cost of the waterproof bag 20 and the additional filtration means 25, since there is no particular handling to be done on the bag, nor cost of assembly.
- Another advantage of a vacuum cleaner according to the present invention lies in the possibility of using any waterproof bag 20 of any capacity in relation to that of the tank 3, without being obliged to obtain a bag specifically designed for this vacuum cleaner .
- Another advantage of the invention and in particular of the waterproof bag 20 according to the invention lies in the first filtration which is obtained with the aid of the complementary filtration means 25 and consequently in the increase in the duration of life of the filter 2a associated with the suction system 2. This also has the effect of accentuating the purification of the flow of expelled air 13.
- Another advantage in the use of the waterproof bag 20 according to the invention lies in the confinement of the sucked-in waste, which it provides to the user. The waterproof bag 20 can be easily disengaged from the tank 3 without the risk of spreading outside a more or less large amount of dust sucked.
- Another advantage of the vacuum cleaner according to the present invention lies in its safety in use, in fact if by accident the waterproof bag 20 has a tear inside the tank 3, the waste sucked out of said tank 3 to through the pressure tap 5, will be stopped by the filter 2a and will not be able to penetrate directly into the housing of the engine 2c and damage the latter.
- Another advantage of the vacuum cleaner according to the present invention lies in the use of an additional filtration means 25 comprising at least two layers 30, 31.
- Another additional advantage of the vacuum cleaner according to the invention lies in the positioning of the complementary filtration means. This positioning in the upper part of the tank 3 is advantageous insofar as any vibration transmitted to the vacuum cleaner, for example during its movement, is transmitted by additional filtration means which can thus get rid of clogged dust on its communicating wall with internal volume 21.
- An additional advantage of the present invention lies in obtaining a clean tank 3 despite the suction of waste such as water or oil or any other liquid spilled on a surface to be cleaned. All this waste remains confined in the waterproof bag 20.
- Another advantage of the vacuum cleaner according to the present invention lies in the use of the apparatus with the complementary filtration means 25 without putting a bag in the tank 3, to suck up a large amount of water.
- Another advantage of the vacuum cleaner according to the present invention lies in the use of a plate 33 in which is inserted the complementary filtration means 25, thus making the positioning of the complementary filtration means 25 on the tank 3 easier.
- Another advantage of the present invention lies in the use of a washable and reusable complementary filtration means, with or without a waste collection bag.
