Definitions
- the present invention relates to the field of vacuum cleaners using a waste separation step by a pleated type filter.
- the most commonly used vacuum cleaners to date use paper filters interposed between a motor-fan unit and an air supply tube for the separation of dust and waste. Air pollution control takes place through said paper or non-woven material filter which mechanically traps particles above the pores of the filter medium.
- bagless vacuum cleaners employing a cyclonic or inertial separation, to eliminate waste.
- the polluted air enters tangentially into a separation chamber provided with a grid or a primary separation allowing remove coarse particles before going into a secondary separation to remove residual fine particles.
- a separation chamber provided with a grid or a primary separation allowing remove coarse particles before going into a secondary separation to remove residual fine particles.
- the inertia separation vacuum cleaner described in document EP 1 535 562 has an air inlet duct opening in a tangential direction into a primary waste separation chamber, said chamber being of generally cylindrical shape. The central part of this chamber opens onto a duct in connection with the suction device, which duct has a secondary filtration assembly in order to remove the finer particles.
- An evacuation channel allows the recovery of centrifuged waste in a sealed collecting tank.
- This waste evacuation channel is located at the same level as the air inlet and is placed in a substantially diametrically opposite position relative to the axis of the cylindrical separation chamber.
- the filtration assembly housed in the central part of the vacuum cleaner comprises a primary filtration device and a secondary fine filtration of the waste conveyed by the air flow.
- the air flow in the separation chamber due to its tangential arrival, and due to its evacuation in the central part of the separation chamber, describes a vortex path favorable for the separation of waste.
- the primary filtration device positioned in the main separation chamber, in the upper part of the filtration assembly, is constituted by a cylindrical portion pierced with grid-shaped holes, said holes allow the flow of air flow towards of the secondary filtration chamber.
- the main separation chamber in particular its geometry, as well as the grid for the separation of large waste are configured for the most efficient centrifugal separation possible.
- the majority of the waste collected by the squeegee assembly is discharged directly into the waste recovery tank.
- This secondary filtration is traditionally constituted by a pleated paper filter of cylindrical shape arranged coaxially with the main separation chamber.
- a vacuum cleaner comprising a first filtration by a cyclone, the air then being conveyed to the motor through a filter.
- This filter is preferably a fine metal filter that can be cleaned using a small brush supplied with the device.
- a filter unclogging device requires, on the one hand, the intervention of the user, and on the other hand generates significant contact with the fine dust embedded in the pores of the filter.
- this operation must take place after partial disassembly of the vacuum cleaner, which does not facilitate the operation.
- Such a vacuum cleaner therefore already makes it possible to automate the unclogging operation of the filter, but this operation may not be carried out or only partially if the user does not rewind his cord or if he unwinds only a short length of cord. .
- a device can be complex to implement if the reel is removed from the filter to be unclogged.
- the present invention therefore aims to bring about an improvement to vacuum cleaners having a primary separation of the waste (by centrifugation, inertia, but also by water filtration or by a large mesh filter) as well as a secondary separation of the finer waste, by proposing a device for unclogging the secondary fine filter which reduces the intervention of the user for maintenance as much as possible, while being simple to implement.
- the present invention relates to a waste separation device for a vacuum cleaner comprising a filtration system, said device comprising a pleated filter as well as a device for unclogging said filter, said unclogging device having at least one mechanical biasing element resting on the wall of the filter, one of the parts among the filter or the mechanical stressing elements being movable relative to the other part, characterized in that the separation device is a secondary separation device disposed downstream of 'a primary filtration system, and in that a gear motor automatically performs a relative mechanical movement between the mechanical biasing elements and the filter.
- the primary filtration is carried out by a cyclonic phenomenon or by inertia in a separation chamber connected to a waste recovery tank, which makes it possible to separate a large quantity of waste.
- the pleated filter is tubular and the relative movement between the mechanical biasing elements and the filter is a circular movement.
- the tubular characteristic of the secondary filter saves space while providing a large developed filtration area.
- the main advantage of the unclogging device according to the invention is therefore to reduce the maintenance operations on the filtration unit and to reduce the cost of replacing the filters. Said device also limits the loss of power linked to clogging of the filter, the performance of the vacuum cleaner thus remaining permanently constant.

- FIG. 4 shows more precisely the various constituent elements of the filtration assembly 9 and in particular:
- the body 15 defining the secondary filtration chamber 12 and housing the filtration means
- the main separation chamber 6 positioned in the upper part of the body 15 comprising the opening 20 in the direction of the connecting duct 8 towards the container 37 for recovering waste
- this return elbow 16 directing the air coming from the pleated filter 13 towards a pipe 11 then towards the suction motor, and located under the main separation chamber, this return elbow being formed by a dome 162 in connection with the central part of the tubular filter, this dome 162 being bordered in part by an opening 164 connecting the internal part of the primary filter 17 to the external part of the pleated filter,
- a pleated tubular filter 13 positioned vertically in the lower and central part of the body 15, which lower part forming the secondary separation chamber,

- the waste-laden air arrives via the inlet mouth 5 tangentially into the primary separation chamber 6, in the direction F, the high-speed air flow rotates around the ring formed between the primary filter 17 and the walls of the chamber 6 and discharges, through the opening 20 (arrow F 1 ), coarse waste which is expelled to the recovery tank 37.
- the air flow then enters through the holes of the primary filter 17, then through the opening 164 in the secondary filtration chamber (arrow F 2 ), between the body 15 and the pleated filter.
- the air then passes through this filter from the outside to the inside, discharging residual dust and fine particles as it passes, and rises in the central and upper tubular part of said pleated filter 13 (arrow F 3 ).
- the dome 162 In the upper part of the filtration assembly is located the dome 162 forming the return elbow 16 of the filtered air which then directs the flow towards the duct 11 and the motor responsible for the suction (arrow F 4 ).
- the unclogging device according to the invention is placed in a sealed manner in the lower part of the filtration assembly so as not to disturb the air circulation in the filtration assembly and not to hinder the separation of the particles under the effect of centrifugal force.
- the drive mechanism of the moving part or parts is positioned under the tubular filter 13 and the mechanical biasing elements inside the tubular filter 13.
- the mechanical biasing elements can be located outside the tubular filter 13.
- the unclogging device comprises a geared motor 10 which actuates in rotation mechanical loading elements 23 via a transmission 19.
- the transmission 19, advantageously located under the filter 13, has the function of transmitting a rotation between the drive shaft of the gear motor 10 and an axis 22 supporting the mechanical biasing elements 23.
- Said drive shaft is offset relative to the central axis of the overall cylindrical filtration unit 9.
- the mechanical stressing elements are mobile and the filter 13 is fixed.
- the transmission 19 can for example comprise gears 24 connected by a belt 21, or comprise any other device making it possible to transmit a rotational movement between one point and another.
- the mechanical biasing elements 23 may for example be in the form of fingers, which fingers scrape the folds of the filter 13 so as to cause the dust to fall when they are rotated. These fingers can be positioned in the middle part, substantially halfway up the pleated tubular filter, or at other levels, depending on their shape and the configuration of the filtered.
- At least two mechanical biasing elements 23 are arranged at the end or on the axis 22 serving as a support, advantageously a greater number of said elements, typically six, will also be disposed on the interior or exterior perimeter of the tubular filter, and possibly distributed over the height of the filter, being arranged at different levels on the axis 22.
- Said mechanical biasing elements 23 can also be metal wires bent in arcs and fixed on one side to the lower part of the axis 22 and on the other side to the upper part of said axis at the upper level of the pleated filter. According to this variant, the convex outer portion of the metal arc presses on the filter and the friction generated during rotation causes the dust to fall and unclog the filter.
- the mechanical biasing elements animated in rotation to shake the pleated filter can also consist of fins or blades.
- Various other rigid or flexible means can be envisaged for mechanically shaking the filter and causing the fall by gravity of the dust, without departing from the scope of the invention.

- FIGS. 1 to 6 An advantageous example of embodiment of the invention is illustrated in FIGS. 1 to 6, however, there are multiple variants for the design of a vacuum cleaner of the aforementioned type comprising the device for unclogging the secondary filter according to the invention.
- the vacuum cleaner evacuates the largest and most heavy during primary separation.
- the finest debris essentially consisting of fine dust, is stopped by the pleated filter 13.
- the pleated filter releases a part of the fine dust which also falls into the waste collection tank 37.
- said waste recovery tank 37 shown in FIG. 6, is arranged in two parts and comprises:
- a secondary compartment 32 accommodating fine debris and dust coming from the secondary separation and the fine filter, after the unclogging operation
- the main and secondary compartments are advantageously chosen to have an overall parallelepiped or cylindrical shape and are preferably shaped to best fit with the various components of the vacuum cleaner carried by the frame 1.
- the main compartment 31 is of larger capacity than the secondary compartment 32, and located on the rear and in the lower part of the vacuum cleaner, in the extension of the duct 8 and substantially positioned opposite the flow of polluted intake air, which flow arriving through the intake port 5.
- the secondary compartment 32 is positioned below and substantially vertical to the secondary separation chamber, under the filtration assembly 9.
- the height of the secondary compartment is limited so as to avoid deterioration of the compactness of the cyclonic vacuum cleaner and a height excessive.
- the upper parts of the two compartments have cutouts allowing easy engagement of the recovery tank in a reception housing 7 in the vacuum cleaner. Said cuts are made according to planes inclined towards the front of the vacuum cleaner.
- This pointed shape of the waste container facilitates its insertion into the housing 7, the compartment 32 serving as a reference for the insertion of the container 37 in its housing. Therefore, the shape of the recovery tank as a whole is designed to fit optimally in the housing 7.
- the waste recovery container 37 comprises at least one gripping device allowing the handling of said container for maintenance operations.
- This gripping device is preferably a handle 34 oriented vertically housed on the rear of the container, approximately halfway up and in the center of the external face of the main compartment 31, as illustrated in FIG. 6.
- a main variant of the embodiment which has just been presented consists in making the filter mobile, the mechanical biasing elements then being fixed.
- the transmission of movement between the geared motor and the filter could, for example, be obtained by an assembly of gears as will be described later.
- FIGS 7 to 13 show another embodiment of the present invention where the main difference compared to the embodiment illustrated in Figures 1 to 6 relates to the pleated tubular filter 130 which, on the one hand is positioned horizontally in the chamber 120 of the separation device 90, and on the other hand is movable relative to the mechanical biasing elements which are fixed.
- the main waste separation device is in accordance with what has been described above.
- the primary filter 170 advantageously carries two arches 172 diametrically opposite and intended to limit the movement of the tubular filter in the chamber 120. These two arches are supported on recesses 152 formed in the body 150.
- a compartment 310 for recovering the waste separated by the main device is removably mounted on the upper part of the device 90 for separation by cooperation between lugs and hooks 312, coming from the tank, with corresponding housings 92, produced in the body 150. This compartment is in accordance with that described in application EP 1 535 562.
- FIG. 8 shows a partial exploding view of the separation device 90.
- This figure also shows Ie geared motor 100, as well as part of the unclogging mechanism.
- the gear motor 100 is arranged on the body 150 opposite the air outlet opening 158, by means of a housing 104.
- the drive mechanism of the filter 130 comprises two toothed wheels 106, 108, one of the wheels, in this case the wheel 106 being linked to the filter 130, l the axis of this wheel corresponding to the axis of rotation of the filter 130.
- the other wheel 108, meshing with the previous one, is rotated by the drive shaft 102 of the gear motor 100.
- the wheel 108 is larger than the wheel 106 in order to reduce the speed of rotation of the filter relative to the speed of the shaft 102 of the gear motor.
- the number of wheels can be higher depending on the characteristics of the geared motor used and the desired speeds.
- the wheel 106 is disposed outside the body 150, while the wheel 108 is disposed inside, in the chamber 120.
- the body 150 thus comprises an openwork part 153 allowing the mechanical connection between the wheels 106 and 108.
- the housing 104 will be sealed on the body 150.
- the wheel 108 is linked to a flange 132 constituting, with another flange 134, the mechanical supports of the filter envelope 136 of the pleated filter 130.
- the unclogging means also comprise a cleaning assembly 140 of the pleated filter 130 comprising six elements for mechanically biasing the pleats of the filter 130.
- This assembly 140 is detailed in FIGS. 10 and 11.
- the cleaning assembly comprises biasing elements 146 , 148 in the shape of bent fingers and connected to a central axis 143. One end of this axis has a cylindrical cap 144, while the other end comprises in particular a retaining lug 142.
- the six mechanical stressing elements arranged inside the filter, in contact with the wall of said filter, comprise two groups of three fingers, arranged at two levels along the length of the filter, said fingers of each group being angularly distributed around axis 143.
- each finger 146, 148 has a portion swollen radially outward, respectively 1460 and 1480.
- the fingers 146 are not strictly located in the extension of the fingers 148.
- the two groups of fingers are offset by an angle ⁇ , which, according to the example proposed, is of the order of 30 °.
- Figure 12 is a top view of the filtration device 90, without the cover 6, the filter 170, or the tank 310.
- Figure 13 is an enlarged view of a detail of Figure 12.
- the assembly 140 is kept stationary in the body 150, in particular by the retaining lug 142 arranged in the bottom 156 of a groove 154, elements also visible in FIGS. 7 and 8.
- the end 144 of the axis 143 is held in an opening 135 of the flange 134.
- the gear motor drives the tubular filter 130 in rotation about the fixed axis 143 of the cleaning assembly 140.
- the air flow is the same as that described above.
- the bulged parts 1460 and 1480 of the fingers 146, 148 come to stress the folds of the envelope 136 of the rotary pleated filter. Part of the dust retained by the filter is then released and falls into compartment 320.
- a tubular filter arranged horizontally that is to say one whose axis of symmetry is horizontal, it indeed seems advantageous to put the filter in rotation with respect to the biasing elements. In fact, the reverse would not unclog the folds located in the upper part with good efficiency since the dust thus suspended in the air, by gravity, would redeposit on substantially the same folds.
- FIG. 11 shows an angular positioning of the cleaning assembly 140 in the chamber 120 which gives good results.
- Figures 14 to 16 show an alternative embodiment, where the inlet pipe 405 for waste into the main separation chamber 408 closed by a cover 406 is substantially horizontal.
- the waste container 410 is more in accordance with the example illustrating the first embodiment of the invention, by presenting a vertical grip handle 412 as well as a double waste tank composed of a compartment 414 for waste separated by the main separation device and a compartment 416 for waste from unclogging. The waste is conveyed to the compartments 414, 416 respectively by conduits 415, 417 integrated into the container 410.
- the compartments 414, 416 are removably mounted by a hinge 418, a latch 419 enabling the compartments to be kept in tight connection with the conduits 415, 417 of the tank, by means of seals sealing.
- Figure 15 shows, like Figure 9, an exploded view of the secondary filter 430 located under the separation chamber, as well as the unclogging device.
- the device also comprises a gear comprising a wheel 437 of large size linked to the flange 432 and meshing with a wheel 438 whose axis is connected to the axis 452 of the geared motor 450.
- the scraper blade 440 is fixed and the cylinder is rotated around said blade.
- the scraper blade 440 is illustrated in more detail in FIG. 16. It includes a retaining lug 442, as well as an axis 443 on which are attached two mechanical biasing elements 444, 446 of the pleated envelope 436.
- the ends of the elements 444, 446 of mechanical stress advantageously comprise a bulged part, respectively 445, 447, being in the form of small cylinders which allow a gentle interaction with the pleated envelope, in order to damage the surface as little as possible. of the unclogging operation.
- these cylinders 445, 447 are covered with a lubricating material or having a very low coefficient of friction, such as PTFE for example.
- the mechanical biasing elements are oriented downwards so that unclogging is more effective.
- Figure 15 shows these elements oriented upwards only for better visualization.
- the scraper blade can be either integrated in the filter (for example by gluing), or removable from this filter and assembled by a reversible connection of the clipping type.
- the unclogging device can be positioned in the secondary filtration chamber outside the filtering device.
- Another conceivable variant consists in modifying the air flow in order to force the polluted flow to pass through a flat secondary filter, from the bottom upwards, said flat filter being preferably positioned on an inclined support, the mechanical stressing elements pressing said filter by the air discharge face so as to facilitate unclogging by scraping, according to relative rectilinear or back-and-forth movements between the biasing elements and the surface of the filter.
- the dust, coming from unclogging under the action of the device of the invention is recovered by gravity in the lower part of the vacuum cleaner in a compartment provided for this purpose, which compartment being hermetically closed so as to avoid pressure drops during the operation of the vacuum cleaner.
- the action of the unclogging device is not permanent during the operation of the vacuum cleaner. Indeed, a continuous operation of the unclogging device is not necessary because of the low fouling speed of the filter on the one hand, and because of the wear caused by friction on the material, on the other hand .
- the gear motor operates intermittently.
- the gear motor starts up, preferably according to the invention, each time the vacuum cleaner is stopped.
- a delay of one or a few seconds of waiting after the engine stops will allow the unclogging efficiency not to be too disturbed by the vacuum generated by the operation of the engine.
- the filter may be flat or tubular, made up of various materials and the circulation of air in the filter assembly designed in different ways, without going beyond the ambit of the invention.
