Definitions

  • the invention relates to a waste collection tank for a so-called "bagless” vacuum cleaner, comprising a first separation of the waste by a device of cyclonic type, or inertial, or by a grid with large meshes, and a second consecutive separation at the first, by a fine filter.
  • polluted air enters tangentially into a separation chamber with a grid or primary separation to remove coarse particles before moving to secondary separation to remove fine particles residual.
  • Another vacuum cleaner having a primary separation removing the heavier and larger waste by a bagless device cyclonic type, said vacuum also comprising a secondary separation for fine debris and a waste container with two separate compartments is also described in the document US 2004/211025 .
  • the vacuum cleaner with inertia separation used in the context of the invention has an air inlet duct opening in a tangential direction in a primary separation chamber waste, said chamber being of generally cylindrical shape.
  • the central portion of this primary separation chamber terminates in a conduit in connection with the suction device, which conduit has a secondary filtration assembly to remove finer particles.
  • An evacuation channel makes it possible to recover the centrifuged waste during the primary separation in a sealed collecting tank.
  • This waste disposal channel is located at the same level as the air inlet and is placed substantially diametrically opposite position relative to the axis of the cylindrical separation chamber.
  • the airflow in the separation chamber due to its tangential arrival, and because of its evacuation in the central part of the separation chamber, describes a swirling path favorable to the separation of the waste.
  • the primary filtration device positioned in the separation chamber main, in the upper part of the filter assembly, is constituted by a cylindrical portion pierced with grid-shaped holes, said holes allow the passage of air flow towards the secondary filtration chamber.
  • the main separation chamber including its geometry, as well as the grid for the separation of large waste are configured for the most efficient centrifugal separation possible, in fact the majority of the waste collected by the nozzle assembly is discharged directly into the waste bin.
  • the fine part of the waste, especially low-particle dust, passes through the primary filtration grid. Secondary filtration is therefore necessary before the air is evacuated through the suction unit.
  • This secondary filtration is traditionally constituted by a folded paper filter of cylindrical shape arranged coaxially with the main separation chamber.
  • the waste transported by the air stream from the suction nozzle of the vacuum cleaner is thus eliminated in two stages, the coarse waste and the heavy particles are removed by the primary filtration and the fine particles by the secondary separation, in this case the fine filter.
  • Vacuum cleaners comprising a dust-stop filter are also known, automatic filter unclogging devices which can be connected for example to the rewinding of the power supply cord, as described in document FR 2027213 .
  • Such devices manual or automatic, thus allow to dislodge some of the dust embedded in the filter, said dust better joining the other waste collected.
  • the invention therefore aims to solve these major problems by providing a single waste tray but compartmentalized and adapted form to ensure a high compactness of the vacuum cleaner.
  • the present invention relates to a waste collection hopper for a vacuum cleaner comprising a primary separation removing the heavier and larger waste by a bagless device of cyclonic type, or by inertia, or by a grid with large mesh, said vacuum comprising also a secondary separation for fine debris and dust by a suitable filter, said filter comprising a declogging device for extracting from the filter part of the waste retained, characterized in that said waste collection tank comprises two separate compartments, a main compartment for the recovery of waste from primary separation, and a secondary compartment for the recovery of waste resulting from the operation of the unclogging device.
  • FIG. 1 illustrates a cyclonic vacuum cleaner comprising the invention, such a device is conventionally constituted by a frame 1 supported by wheels 2 and a front wheel 3 allowing the movement and orientation of the vacuum cleaner during its operation.
  • the cyclonic vacuum cleaner comprises a filtration assembly 9 formed by the main separation chamber 6 and a cylindrical chamber for the secondary filter located in an immediately lower part, the two chambers being in aeraulic relationship with each other.
  • the engine block 4 is placed on the front of the apparatus, the incoming air stream loaded with waste arrives in the inlet mouth 5 and enters tangentially into a main separation chamber 6.
  • Said main separation chamber 6 has an opening 20 for the discharge of waste to a waste collection tank 37.
  • a conduit 8 connects the waste collection tank and the main separation chamber.
  • the waste-laden air arrives through the inlet mouth 5 tangentially in the primary separation chamber 6, 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, coarse waste which is expelled to the tank 37 recovery.
  • the air flow then enters through the holes of the primary filter 17, then through the opening 164, in the secondary filtration chamber, between the body 15 and the pleated filter.
  • the air then passes through this filter and discharges residual dust and fine particles as it passes and rises in the central and upper tubular portion of said pleated filter 13.
  • the dome 162 forming the return elbow 16 of the filtered air which directs the flow to the pipe 11 and the motor 4 charged with suction.
  • the vacuum cleaner comprises a geared motor 10 placed on the frame 1 actuating the device 14 for unclogging the filter 13 constituting the secondary separation.
  • the unclogging device comprises mechanical biasing elements 23 positioned on the axis of the filter assembly, which filter assembly is of generally cylindrical shape.
  • the geared motor 10 actuates in rotation the mechanical biasing elements 23 via a transmission 19.
  • the unclogging device according to the invention is placed in the lower part of the filter assembly so as not to disturb the flow of air in the filter assembly and not to hinder the separation of the particles under the effect. centrifugal force.
  • the transmission 19, advantageously located under the filter 13, has the function of transmitting a rotation between the drive shaft of the geared motor 10 and an axis 22 supporting the mechanical biasing elements 23. Said drive shaft is deported by relative to the central axis of the overall cylindrical filtration assembly 9.
  • the transmission 19 may for example comprise gears 24 connected by a belt 21, or include any other device for transmitting a rotational movement between one point and another.
  • the mechanical biasing elements 23 may be for example in the form of fingers, which fingers scrape the folds of the filter 13 so as to drop the dust 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 filter.
  • the action of the unclogging device is not permanent during operation of the vacuum cleaner. Indeed, a continuous operation of the unclogging device is not necessary because of the low filter fouling rate on the one hand, and because of the wear generated by the friction on the material, on the other hand .
  • the unclogging device operates intermittently.
  • the geared motor is put into operation, preferably according to the invention, at each stop of the vacuum cleaner.
  • the vacuum removes larger and heavier waste during primary separation.
  • the finest debris consisting essentially of fine dust is stopped by the pleated filter 13.
  • the pleated filter releases a portion of the fine dust that also fall into the waste tank 37.
  • the main and secondary compartments are advantageously chosen parallelepipedal or cylindrical overall shape and are preferably shaped to fit better with the various components of the vacuum carried by the frame 1.
  • the main compartment 31 is larger than the secondary compartment 32, and located on the rear and in the lower part of the vacuum, in the extension of the conduit 8 and substantially positioned opposite the flow of polluted intake air, which flow arrives through the intake port 5.
  • the secondary compartment 32 is positioned below and substantially vertically to the secondary separation chamber, below the filter assembly 9.
  • the height of the secondary compartment is limited so as to avoid deterioration of the compactness of the cyclonic vacuum cleaner and excessive height of the apparatus.
  • the upper parts of the two compartments have cutouts for easy engagement of the recovery tank in a housing 35 in the vacuum cleaner. Said cuts are made according to inclined planes towards the front of the vacuum cleaner.
  • This pointed form of the waste container facilitates its insertion into the housing 35, the compartment 32 serving as a reference for the insertion of the tray 37 in its housing.
  • the shape of the collection pan as a whole is designed to fit optimally into the housing 35.
  • the waste collection tank 37 comprises at least one gripping device for handling said bin for maintenance operations.

  • gripping means different forms, the latter can be made in the same material as that of the compartment to which it is attached or in a different material. Said gripping means may be manufactured during the production of said compartment or be reported in a subsequent step.
  • said gripping means may, for example, be considered recessed handles on some of the walls of the main compartment 31 and different forms of handles, without departing from the scope of the invention.
  • the handle and the shape of the tray facilitates the disposal of waste contained in the compartments by the user, who can perform this maintenance operation without getting dirty.
  • this connection can be designed according to a beam positionable at different heights between the two compartments.
  • beams or connections can be used, the thickness and the structure of these elements can be very variable according to the mechanical constraints and the desired design for the recovery tank as a whole.
  • connection between the two compartments may, for example, be imagined to join the two compartments by a side without connecting beam and manufacture compartments of shapes and volumes various useful.
  • the recovery tank 37 once positioned in the vacuum cleaner, must not allow air intake which would reduce the suction power of the device, also a sealing device is provided between the upper parts of the two compartments 31, 32 and the fixed parts opposite disposed on the frame 1 of the vacuum cleaner.
  • the compartments can be sealed in different ways, for example by means of a plastic or rubber profile acting as a seal disposed in the housing 35.
  • the seal may be positioned at the upper perimeter 36 of each compartment opening 31 and 32, and thus carried by the collection container itself. It can also be imagined other sealing means without departing from the scope of the invention.
  • the Figures 5 to 8 show an alternative embodiment of the vacuum cleaner equipped with the present invention.
  • the separation device has a substantially horizontal waste inlet duct 405, said duct penetrating into the main separation chamber 408 closed by a lid 406.
