Definitions

  • the present invention relates to a vacuum cleaner nozzle, and more particularly an improvement in dust removal performance carpet-like surfaces.
  • a vacuum cleaner nozzle is generally in the form of a housing usually made of plastic, in particular comprising a base plate which, associated or not with a cover, delimits a suction channel.
  • the base plate has at least one flow channel open towards the surface to be cleaned and ventilation communication with the suction channel.
  • Such a nozzle 100 includes a scraper rule made of rubber material, having two lips 139 and 140 articulated around a fastener 121. On either side of this rule are arranged openings connecting the flow channel 141 with the suction channel 120.
  • the lip 139 closes the opening 260. The air is then sucked under the front edge 132 of the nozzle.
  • the rule allows, not only to collect and scrape the dust on the surface to be cleaned, but also to close the half-channel located at the back of the ruler relative to the direction of travel.
  • a vacuum cleaner nozzle comprising a scraper rule arranged in a fixed manner in the median plane of the squeegee flow channel and allowing the carpet hairs to be spread in order to reach the encrusted dust. If such a nozzle is more suitable for carpet type surfaces, due to the rigidity of the rule used, it is not very effective because part of the suction flow does not use the effect of the rule to increase the dust release power. In addition, the effect of the rule is not entirely satisfactory.
  • the object of the present invention is to remedy the drawbacks of the prior art by offering a nozzle with improved performance, while remaining reliable at long term and reasonable cost.
  • the scraper blade capable of being in contact with the ground lying upstream, in other words in front of the channel with respect to the direction of movement, the hairs of the carpet is then spread by the passage of the blade, which allows the dust to end up in the flow channel just open to the channel suction.
  • the function of the blade is therefore no longer to collect dust under the flow channel whose effectiveness is questionable, but to solicit the soil fibers to dislodge dust, immediately taken in a air flow.
  • the squeegee is moved in the wrong direction, it is best to close this specific channel to defer power suction on other more suitable flow channels of the squeegee.
  • the sealing means could be based on a cylinder driven in rotation by the squeegee wheels, this cylinder being fitted with weights, the point of rotation would be located on the periphery and forming projections that in a direction of rotation, these projections acting on an interlocking mechanism, or release, a channel shutter. Such a mechanism could be quite complicated.
  • the blade is movable under the effect of friction against the surface to clean in one direction, respectively in another direction, depending on the direction of displacement of the squeegee, and is connected to sealing means, respectively opening, of the adjacent canal.
  • the blade may be integral with the end of a plate movable in translation in grooves arranged in the lower plane of the squeegee perpendicular to the flow channel, this plate having, next to the blade, an opening corresponding to the mouth of the flow channel followed by a closing flap.
  • This plate is then arranged so that the friction of the ground, when the nozzle is advanced, pushes the blade towards the channel so that the opening of the plate comes in correspondence, and that, when the nozzle is pulled back, the soil friction moves the blade away from the channel bringing the closing flap into position.
  • the blade can be pivotally mounted around its upper edge on an axis parallel to the surface to be cleaned, this axis carrying a pinion meshing with a toothed wheel, or with a gear, animating at the outlet a shutter of obturation at the intersection of the flow channel and the suction channel.
  • a plate is mounted movable in rotation around an axis parallel to the channel, this axis separating this plate into a blade lower scraping and an upper channel shutter, this axis being arranged on one side of the mouth of the flow channel, the flap part shutter being capable of coming to bear against two stops arranged respectively at the front and rear of the canal.
  • a reverse scraping-opening device has thus been produced very simply.
  • This mechanical action which does not fail to occur as soon as the squeegee is displaced, can be reinforced by the presence of a foam, a joint, or a felt at the upper end of the shutter or at the internal walls of the squeegee duct in relation to the flap, so that during of the blade pivoting, the foam, the seal or the felt are slightly tablets and ensure a good seal and therefore a good sealing of this part of the canal.
  • the axis of the plate is located between one tenth and one third of the plate height, leaving most of the plate in operation shutter.
  • the scraper blade protrudes from a height between a and five millimeters when the shutter is in abutment against a stop. Thanks to this scraper blade, we can better define the ground clearance of the squeegee at the level of the flow channel, therefore the air flow.
  • the axis of the plate is arranged in the plane center of the channel which it splits into two channels, the shutter part being capable of coming into abutment against two stops arranged respectively at the front and back of the canal.
  • two channels open side by side, and the axis of the plate being arranged between the two adjacent channels, the part of shutter being capable of coming to bear against two stops arranged respectively at the front of the front channel and at the rear of the rear channel.
  • the surfaces of the two parts of the flow channel and / or of the part of the suction channel immediately adjacent to the surface to be cleaned, located on either side of the blade are significantly different. A surface greater then induces a vertical force to keep the squeegee on the ground more important.
  • This structure then makes it possible to differentiate the passage of the nozzle in one direction or in the opposite direction, the squeegee undergoing a force of attraction towards the ground stronger when the squeegee is moved in one direction rather than in the direction opposite.
  • This difference in area can also be achieved by a position asymmetric of the plate or by the profile of the flow channel, or by patches on the plate.
  • the level of penetration of the blade into the carpet can be different depending on the direction of movement of the squeegee, in order to cause a displacement force of the squeegee by the user different according to the direction of displacement.
  • This level, or ground clearance can be obtained by an angle of different blade rotation depending on the direction of movement, or by an axis of rotation of the off-center plate relative to said plate.
  • the nozzle has a mechanism for adjusting the height of the blade in the flow duct.
  • this device adjust the blade height in the factory according to the type of carpet frequently encountered in various countries, and on the other hand, it allows the user to adapt his nozzle to the different types of carpet he may have in his possession, in order to get the most out of his device.
  • the latter comprises at least one sealing flap located at the front and / or rear of the canals.
  • FIGS 1a and 1b schematically illustrate the general principle of the invention.
  • Two walls 1a and 1b of a nozzle define a suction channel 2 opening into a flow channel 4 open towards the surface to be cleaned.
  • the direction of movement F1 can be considered as a usual movement of the squeegee forward, direction F2 as a displacement of the squeegee backwards.
  • the surface to be cleaned is of the carpet type and includes inlaid bristles. dust 12.
  • a generally vertical plate 6 and of length similar to that of channel 4 is rotatably mounted around an axis horizontal 8 close to the front internal face.
  • This plate 6 forms a blade lower scraping 9b below the axis 8 and a shutter 9a at above this same axis.
  • the lower edge of the scraper blade in contact with carpet pile can be bevelled if you want a whip effect important on the hairs, or rounded to protect the floor to be cleaned as much as possible.
  • the upper edge of flap 9a can be completed with a flexible linear joint sealing.
  • the height of the blade can be adjusted to such height according to the networks commercial and / or when using a vacuum cleaner fitted with such a nozzle, in such a way that the blade arrives at the top of the hairs (touch) or more depth, for example at mid-height of the hairs, choice also depending on the type of carpet.
  • the flap 9a is plate against the front internal face of channel 4 when the nozzle is pushed towards the front according to arrow F1.
  • the carpet pile is then agitated by the blade scraping which favors the extraction of dust behind this blade scraping.
  • This dust is immediately collected by suction. Yes now the squeegee is pulled back, distorting the relationship between the blade scraping and the flow channel, then the tilting of the plate 6 brings the shutter 9a in the closed position and the scraper blade is found slightly raised.
  • Figures 2a, 2b and 3 show, very schematically, the general principle of the invention in the case of a large flow channel.
  • Two internal walls 1a and 1b of a squeegee 20 define a suction channel 2 opening into a channel 4a, 4b, open towards the surface to be cleaned and extending preferably in a direction perpendicular to the plane of the figure.
  • channel 4a is called “front” channel
  • channel 4b channel "rear”, taking into account the orientation of the nozzle according to FIG. 3.
  • the squeegee 20, as shown in Figure 3, can be provided with another channel suction 18.
  • it can have one or more wheels 14 in order to facilitate its movement.
  • a plate 6 is disposed in the nozzle and extends at least partially in the flow channel along its largest dimension, but can also extend into the suction channel. This plate is mounted on an axis 8 oriented parallel to the general direction of the plate.
  • the axis 8 On either side of the axis 8 extend two arms 9a and 9b defining respectively the shutter and the scraper blade, and the ends of which define the edges of the plate 6.
  • the end of the flap 9a allows block the part of the suction channel located above the front channel 4a or of the rear channel 4b according to the orientation of the plate 6.
  • the arm 9a may have a complex shape in the form multiple arms, giving the blade a Y or T shape, for example.
  • the plate 6 can be thick or thin depending on the type of stress desired, and have a wider shape at its end capable of being in contact with the ground than at its axis of rotation.
  • the other arm 9b is generally shorter than the arm 9a and is largely located in the flow channel. This arm, in normal position of the squeegee, leaves the squeegee, so that the edge of the blade, defined by this arm, can be in contact with carpet-like surfaces, even when the blade is pivoted around the 'axis 8.
  • the plate 6 pivots around the axis 8, by friction on the pile 10 of the carpet. from then, the arm 9a can bear against one of the walls 1a or 1b, or against a stopper attached to one of the walls.
  • the plate 6 can therefore only pivot at an angle limited on either side of its vertical position, achieving a obturation of the adjoining canal.
  • this arm 9a can be bevelled and / or covered with a foam, a seal or felt to reinforce this filling. It is also possible to overmold a soft plastic part at the end of this arm or these arms when the arm 9a is made up of two parts.
  • the arm 9b does not touch the floor in order to find a more classic aspiration, without specific activity of the nozzle.
  • the rotation of the plate around its pivot point can be symmetrical or asymmetrical in order to differentiate two directions of movement of the squeegee.
  • This asymmetry can be achieved by a judicious positioning or sizing of the stops and / or a off-center of the plate in the suction and / or flow channel.
  • a first improvement consists in increasing the tightness and disadvantaging the passage of air under the opposite edge of the squeegee, either by increasing the surface contact, either by placing sealing flaps 16a, 16b, on the side and on the other side of the plate, as shown in Figure 3, and, in a more general, at the front and / or rear of the suction or flow channel when it exists.
  • FIGS 4a and 4b show a first alternative embodiment.
  • two plates 22a and 22b are used, each plate containing individually the previously mentioned functions and effects. So the plate 22a is located in a channel 23a, and the plate 22b in a channel 23b.
  • Each plate is pivotally mounted around an axis 28a, 28b. Under the effect of a displacement of the squeegee, the blades, in contact with the bristles 10, pivot in closing the front or rear of the channel, depending on the direction F1 or F2 of movement of the nozzle, via the guide pieces 26a and 26b, of the separation 27 and the longitudinal walls 25a, 25b of the nozzle.
  • Stops can be arranged at several guide pieces 25a, 25b, 26a, 26b, 27 in order to limit the rotation of the plates.
  • stops 29a and 29b have been provided by an appropriate shape of the parts 25a and 25b.
  • flaps 30a and 30b can be placed at the level of the front and rear edges of the squeegee.
  • FIGS. 5a and 5b According to a second alternative embodiment, presented in FIGS. 5a and 5b, two plates are used but only one suction channel is activated. So the channel front 33a is constantly closed, as is the rear channel 33b. Thus, when the squeegee moves along F1 (forwards), the channel 33b is inactive and channel 33a active, the situation being reversed when the squeegee is moved along F2 (backwards).
  • the guide parts are simplified. Indeed, the plates 32a, 32b, pivotally mounted around their axis 38a, 38b, are guided in major part by the internal part of the edges of the squeegee, advantageously having a profile adapted to the shape of the blade, so as to leave only a slight guide clearance during rotation of the plate.
  • the plate has a base at the shutter, the profile of which is in an arc of circle.
  • the guide surfaces of the edges 35a and 35b and of the workpiece separation 37 separating the two blades are also in an arc.
  • a first improvement can be brought by values appreciably different from the contact surfaces with the surface to be cleaned of the two parts of the flow and / or suction channel, located on either side of the blade scraping.
  • This structure makes it possible to have a suction force on the channel 33a different from that on channel 33b.
  • a second improvement consists in modifying the height between the end of the blade and the ground, which we could call ground clearance, by analogy with the automotive field. By creating a more or less significant air leak at the level of the air space, the suction force is also modified.
  • FIGS. 5a and 5b One of the means enabling this difference in ground clearance between the two scraper blades, and presented in FIGS. 5a and 5b consists in rendering asymmetrical the stops of the shutters of the two plates, and this for each plate, this asymmetry being reversed from one plate to another.
  • FIG. 5a during the displacement of the nozzle according to F2, the "active" blade of scraping of the plate 32b pivots by an angle ⁇ , while the blade of the plate 32a pivots by an angle ⁇ 'when the squeegee moves along F1.
  • ⁇ ' more important than ⁇ or vice versa, depending on the configuration of the nozzle, so to obtain this asymmetry of force according to the direction of movement of the nozzle.
  • the angle of rotation ⁇ of the "inactive" blade for scraping the plate 32a when the squeegee is moved in the direction F2, can be more important that ⁇ , causing a vertical rise of the end of the blade of the plate 32a more important than the vertical ascent of the end of the blade of plate 32b.
  • the ground clearance of the plate 32a blade is therefore more important.
  • the blade of the plate 32a only touches the hairs 10, so it doesn't cause extra force to deploy to move the squeegee.
  • the dust 12 is sucked into the channel 33a or into the channel 33b.
  • a main plate 46 rotatably mounted about a pivot axis 48 has air injection channels 47a, 47b. These channels are open to the surface to be treated.
  • channels 47a and 47b are determined, on the one hand by an internal structure 40 of the nozzle, and on the other hand using secondary blades 42a and 42b associated with the main plate 46. These secondary blades are arranged on either side of the main plate in each providing an injection pipe on either side of the plate main.
  • these channels are connected to the outside of the nozzle.
  • the squeegee has air inlet holes allowing air to be injected taken outside the squeegee in channels 47a and 47b, then in the surface to clean.
  • the injection pipe is connected to a container containing treatment products, either in their own right or in association with a outside air intake, as previously described.
  • the treatment products used can be in liquid, powdered form, or in the form aerosols, ... It is then possible to combine a mechanical supply action of air and a physicochemical action by the product treating the carpet.
  • the profile of the secondary blades is studied, in association or not with additional parts, so that the obturation of one of the front channels or rear, due to the rotation of the plate 46, causes, at the same time, closing the air inlet channel opposite the closed suction channel.
  • the blade rotation angle can be identical depending on the direction of movement of the squeegee, or else present a different value, as shown in the figures 6a and 6b, where the angle ⁇ is of absolute value different from the angle ⁇ , leading to a ground clearance of the blade different depending on the direction of movement of the nozzle.
  • the effectiveness of the nozzle having such an embodiment can be increased by the presence of sealing flaps 44a and 44b.
  • blower means which may include a specific heating circuit. It is interesting in this case of collecting air at the engine outlet. This air allows, for example, to dry a carpet.
  • the shape of the duct can be adapted so that the air leaves in the form of an air gap, as described in application FR 98 10227.
  • the internal structure 40 as well as the internal shape of the edges 45a and 45b of the squeegee allow the guiding of the plate 46 and of the blades 42a, 42b, and also constitute stops. These stops can be arranged so asymmetrical with respect to the axis of rotation, thus constituting another means to vary the ground clearance of the scraper blade, as already mentioned in this application.

  • This embodiment also has one of the abutment possibilities associated with the plate 56, constituted by an arm 57 from the internal structure 50 for guiding the nozzle.
