Definitions
- the present invention relates to an improvement relating to vacuum cleaners, and more particularly to the flexible pipes fitted to said vacuum cleaners.
- FIG. 7 One of the configurations frequently encountered in recovery of vacuum cleaner type dust, as illustrated in FIG. 7, includes a suction nozzle 105 in connection with the surface to be cleaned and air-connected to an appliance body 100 comprising a frame inside which is housed a suction group, as well as generally a electric power cord reel of said device.
- a device for waste separation is commonly housed in this device body well that can be inserted further upstream in the ventilation circuit.
- the air connection connecting the squeegee to the frame of the vacuum cleaner often includes flexible tubing 102 allowing easier handling of the nozzle suction, said flexible tubing being generally connected to the nozzle 105 by a handle 103 and a rigid pipe 106.
- a first configuration of these pipes consists of a flexible pipe comprising an internal reinforcement generally made of plastic in the form of a bead arranged, either in the form of a helical spiral, or in a succession rings. This reinforcement makes it possible to prevent the flexible hose from closing on itself.
- a flexible plastic sheath is produced in providing a spirally wound cavity. Then we come and stay in this cavity a metal wire wound in a helicoid, like a spring. Sheath flexible is preferably produced by plastic injection, extrusion or blowing. The metal wire thus stiffens the tubing thus formed in particular by preventing the tubing from closing radially on itself, during the depression of the air duct by the group suction, while offering great flexibility, by the type structure spring from the core of said tube.
- plastic tubing is commonly known as "strech-hose”.
- these tubes have, at rest, a retracted position, the spring effect metallic wire making it possible to lengthen said tubing.
- these pipes not the flexibility of a hose and also have the disadvantage of the spring effect that must be overcome, either to keep them extended during a cleaning operation, either to keep them in a storage position where the hose is generally in transverse bending and tends to return in an upright position.
- Document DE 299 11 311 proposes a flexible hose comprising a flexible envelope whose walls are made of a highly flexible and thus create a space where a multitude of channels can be temporarily overpressure.
- the channels can be lateral and parallel to the pipe or else constitute tori surrounding the pipe and parallel between them. These toroids are connected to each other by lateral channels connected to the overpressure device.
- Such a device therefore presents a solution as to the reduction of the size of the suction duct.
- the use of a multitude small channels to stiffen the duct, as well as the outer casing reduce the expected effect of overall compactness of the device.
- such device is of rather complex design and therefore expensive.
- the object of the present invention is to overcome all the drawbacks mentioned, by proposing a flexible, collapsible flexible hose, while offering flexibility of use without recall effort and easy to transport.
- the present invention is achieved by means of a stiffening means of a watertight flexible duct constituting a portion of the aeraulic suction circuit an electrical vacuum cleaner type vacuum cleaner, said vacuum cleaner vacuum cleaner comprising in particular a suction group capable of creating a suction flow in said aunterlic suction circuit, said circuit ventilation comprising rigid parts upstream and downstream of the duct flexible, characterized in that this stiffening means comprises a tube flexible arranged either longitudinally on said flexible conduit, or as a helical around said flexible conduit, said tube being capable of being inflated by an overpressure fluid.
- the solution chosen is therefore to stiffen the duct by inflating a single tube by a fluid.
- This solution makes it possible to obtain at least the same effects and the same flexibility and handling characteristics as hoses conventional, while using a very flexible conduit, which can be contracted or folded up easily, just like the tube, once the inflation fluid has been emptied.
- the flexible tube can have different arrangements on the flexible conduit, either longitudinally on the flexible conduit, allowing easy deployment of the tube during inflation, either as a helical around the flexible duct.
- This structure facilitates the compaction of the tube when it is not inflated, while ensuring good mechanical strength as well that flexibility and isotropic handling of the conduit during operation of the vacuum cleaner.
- the flexible tube is made by a strip of plastic material or waterproof fabric folded and glued on itself.
- the flexible tube is made at least partially in one slightly stretchy material, which allows it to adapt to overpressure, while offering improved flexibility.
- the flexible tube is fixed to the conducted by welding or gluing, an operation which can be easily automated.
- the welding or the gluing of the tube to the duct is shaped in a helical strip, with the advantages as previously mentioned.
- a variant consists of a joining of the tube flexible on the flexible conduit via a tab, thus allowing to minimize the risk of the tube being torn from the duct during placing under pressure of said tube.
- the flexible tube is fixed on the rigid parts of the air circuit located upstream and downstream of the duct flexible, thereby forcing said rigid parts to move away from each other under the effect inflation of the tube, thereby extending the flexible conduit.
- the fluid used is advantageously air.
- a such a configuration makes it possible to use a fluid of low specific mass, avoiding to weigh down the assembly formed by the tube and the conduit, while avoiding having to have a fluid storage tank when the device is not in use.
- the present invention is not limited to the exclusive use of air as an inflation fluid, the use of a liquid such as water is entirely possible without departing from the scope of the present invention.
- an overpressure of said tube independent of suction group for example by a second motor group or by a hand pump.
- the material used for the realization of the flexible tube is advantageously a plastic material.
- the flexible tube is made of a waterproof fabric, which can be in the form of a synthetic material such as those used for spinnaker cloths or parachute cloths.
- a waterproof fabric in addition to its lightness, allows significantly more compacting than materials plastics, which further increases the compactness of the assembly.
- the tube flexible is concentric with the flexible conduit.
- Such a configuration simplifies the shaping of the flexible hose on the conduit, insofar as it suffices to thread the conduit in the tube, the two diameters being fairly close, then to realize, for example using a mandrel inside the duct, moving in rotation and translation, a welding or gluing strip. A manufacturing mass production at low cost can thus be envisaged.
- the present invention also relates to the production of a portion of a circuit air intake of an electrical dust recovery device vacuum cleaner type, said vacuum cleaner comprising in particular a group suction likely to create a suction flow in said aeraulic circuit suction, said circuit portion consisting of a flexible conduit around which is arranged a stiffening means according to one of the characteristics previously developed.
- the internal surface of the duct flexible and smooth, which reduces ventilation noise and turbulence generated by the passage of the suction current over the internal surface of the leads.
- a second stiffening means is arranged around the flexible suction duct, this second stiffening means being in accordance with one of the characteristics mentioned above and compatible with the first stiffening means disposed around said conduit.
- the second stiffening means is arranged alternately with said first stiffening means.
- the present invention also relates to a portion of the air circuit suction of an electrical type dust collection device vacuum cleaner, said vacuum cleaner comprising in particular a suction group likely to create a suction flow in said aeraulic circuit suction, said portion of the air circuit consisting of a duct flexible around which is concentrically arranged a flexible tube according to the characteristics mentioned previously on this arrangement, as well as the variants relating to this embodiment, the flexible tube and the flexible conduit both being pleated according to the same conformation.
- pleated encompasses both the production of accordion-type pleats, as making rings, or even a helical imprint.
- the inflation of the tube by the fluid allows then to lengthen at the same time the tube and the conduit, these two elements having a pleated common wall which then deploys under the effect of the overpressure.
- the present invention can also be adapted to a flexible duct of the type "strech-hose", consisting of a flexible wall reinforced by a metal wire or plastic formed in a spiral and having a spring effect and constituting a portion of the suction air circuit of an electrical recovery device dust type vacuum cleaner, said vacuum cleaner comprising in particular a suction group capable of creating a suction flow in said circuit suction air, a flexible tube being arranged concentrically around the flexible duct according to the characteristics mentioned previously on this arrangement, as well as the variants relating to this embodiment.
- a flexible duct of the type "strech-hose” consisting of a flexible wall reinforced by a metal wire or plastic formed in a spiral and having a spring effect and constituting a portion of the suction air circuit of an electrical recovery device dust type vacuum cleaner, said vacuum cleaner comprising in particular a suction group capable of creating a suction flow in said circuit suction air, a flexible tube being arranged concentrically around the flexible duct according to the characteristics mentioned previously on this arrangement, as
- This adaptation at least partially compensates for the restoring force metallic or plastic wire of the flexible conduit, and thus avoid annoyances related to the sudden and sudden approach of the device and the user in the event of significant depression in the air circuit.
- the flexible tube can be inflated by an overpressure likely to generate a force greater than the restoring force of the wire metallic or elongated plastic.
- the tube and the conduit are produced by extrusion or by blowing, which ensures the possibility of mass production at low cost.
- the present invention also relates to the production of an apparatus for recovery of vacuum cleaner type waste, including a group suction allowing the creation of a vacuum in an a Vogellic circuit connected to the surface to be cleaned, as well as a waste separation means, comprising a portion of the air circuit conforming to one of the characteristics previously mentioned.
- the waste recovery device comprises, in the inflation circuit of the flexible tube, a valve evacuation of the fluid used, to facilitate the emptying of the tube for a rapid re-folding of the flexible air duct portion.
- the waste recovery device comprises a means of adjustment of the overpressure in the flexible tube, in order to offer a rigidity adjustment of the flexible ventilation circuit portion.
- the flexible pipe constituting a portion of the circuit exhaust air from a waste collection device has a flexible duct inside which air and waste can circulate sucked in by the device's suction group.
- a flexible tube can be stiffened by inflation using a specific fluid is arranged around said conduit.
- the conduit 2 is surrounded, like a spring, by a flexible tube 8.
- the arrangement between the conduit and the tube can be mechanical, by a tape of adhesive or welding. Such an arrangement is necessary insofar as the conduit flexible does not have sufficient rigidity to prevent depression generated by the suction unit does not cause a collapse of the duct on himself.
- an alternative embodiment consists in not linking mechanically as the ends of the tube with the rigid parts of the conduit ventilation located upstream and downstream of the flexible pipe, such as parts 103 and 104 of FIG. 7.
- Figure 1a shows the tube 8 in the deflated state.
- the flexible duct 2 has not been shown in the folded state, although the present invention aims in particular to design a flexible duct which can be easily folded and very compact.
- the flexible tube can be produced by extrusion or by blowing, or alternatively folding and gluing a strip of plastic or waterproof fabric over itself such as the synthetic fabrics used to make parachute sails or spinnaker.
- the flexible tube In operation, when the suction unit of the appliance is switched on running, the flexible tube is inflated and then presents an overpressure capable of stiffen the flexible conduit, which nevertheless retains a certain flexibility.
- the thus stiffened conduit resists the vacuum generated by the suction unit, while being able to have a radius of curvature less than 10 cm.
- Overpressure values between 200 mbar and 1000 mbar allow obtain the desired effects and are compatible with their mode of implementation work by the suction unit of the device.
- Rigidity / flexibility performance depends mainly on the shape of the tube used (circular, oval section, ... as well as the surface of this section), its arrangement around the duct and in particular the way it is related to the conduit, as well as the value of the overpressure. These parameters can therefore be used to adjust the desired flexibility of the hose.
- Overpressure is achieved by air, although a fluid such as water can also be used.
- the air sent into the tube can come from a motor specific to this function, or even a more mechanical and less expensive means such as a hand pump, connected at the open end of the tube.
- a suction group of the appliance is used, the air outlet of the engine then being oriented, using valves, towards the open end of the tube.
- advantage can be provided air leakage, for example by a valve or means for adjusting the pressure in the tube in order to avoid an increase in the overpressure in said tube until the latter burst.
- the fluid is evacuated, either through the booster group, by path reverse, either through an air exhaust valve, allowing quickly fold the hose.
- An alternative embodiment consists in the use of a second tube arranged around the duct.
- This second tube is preferably parallel to the first tube, for example by being rolled up like a helicoid.
- each tube has its own means of overpressure. This independence allows to inflate only one of the two tubes or both, in order to offer a larger range of stiffness (flexibility) of the hose, and also allowing to obtain different lengths of said hose.
- the tube 38 is arranged concentrically around the conduit 30.
- a helical weld or bonding strip, as shown, or alternatively rings, the tube on the duct is made, so that the setting overpressure of the tube produces the expected effect previously explained.
- Such an embodiment is particularly advantageous insofar as where its implementation is possible on a large scale and at low cost.
- the conduit 40 and the tube 48 are both concentric and similarly shaped, in the form of folds 47, by example.
- Reinforcements or more rigid zones can be provided at the level of the folds to properly mark the folds and ensure the reproducibility of the unfolding and re-folding the hose. These reinforcement areas can also reduce the tendency of the duct 40 to close on itself under the effect of the depression.
- ends 42 and 44 of the tube are respectively fixed to the rigid parts 41 and 43 of the downstream and upstream ducts of the aeraulic circuit suction.
- the ends 42 are connected to the booster group of the tube, while the ends 44 are closed.
- a valve 45 allows air evacuation when the user wishes to fold the hose.
- These connections can take various forms, such as that already mentioned: a helicoid, rings, ... or even more random, in order to present an isotropic or anisotropic flexibility. In this idea, it can indeed be comfortable for the user to use a flexible having a fairly high rigidity in a particular direction, and less important in another direction.
- the present invention can also be implemented using a conduit of the "strech-hose" type as previously described.
- Figure 4 shows such configuration, the right part of said figure showing the elongated hose, while the left side represents it in the folded state.
- Such a conduit 50 therefore comprises a flexible envelope 51 inside of which is arranged a mechanical reinforcement in the form of a spring wire 55.
- the wire used can be a metal wire or a plastic wire.
- the tube is glued or welded to the flexible envelope 51 at the areas 59 of contact of the spring wire 55 with said flexible envelope 51.
- the flexible tube is a tube identical to tube 8 previously mentioned and wound in a helix, alternately and parallel to the metallic wire 55.
- the conduit 50 By sending overpressured air into the tube 58, the conduit 50 is forced to lengthen by spreading the turns of the metal wire 55.
- the interest, according to this configuration, is not to stiffen the hose, but rather to produce a force opposing the return force of the spring wire 55, which makes it possible to avoid the disadvantage of an unexpected return of the hose to the frame of the device, or Conversely.
- said flexible conduit 60 is connected to the rigid parts 63 and 61 located respectively upstream and downstream of said suction duct.
- a flexible tube 68 is arranged concentrically with said conduit while being held mechanically and tightly to the rigid parts 61 and 63.
- a channel 69 connects the flexible tube 68 to the vacuum group of said tube.
- the tube 68 In operation, when the tube 68 is inflated with air or any other fluid, it tends to lengthen and move away from one another the rigid parts 61 and 63; of this fact, the conduit 60 elongates.
- This configuration is preferably adapted to allow the realization of a particularly rigid duct.
- the diameter of the tube and / or the value of the overpressure can even be adjusted to obtain rigidity and behavior of the duct close to rigid metallic or plastic tubes.
- the present invention is not limited to the various variants proposed and particular to the proposed arrangements, but also covers mutually compatible combinations of said variants.
- the tube can be arranged longitudinally, being parallel to the conduit, as shown in section, Figure 6, where the conduit 70 is surrounded by three tubes 78.
- the present invention is not limited, in this configuration, when using three tubes arranged around the duct, the number of tubes used depending on the desired stiffness / flexibility characteristics.
