    专利说明:

    [0001] The present invention generally relates to a vacuum nozzle, and in particular to the sole plate of such a vacuum nozzle, whose function is to provide a vacuum cleaner, to be in contact with a soil to be cleaned. In the case where a carpet or carpet covers the floor, the cleaning function depends on the interaction of the sole with the carpet or carpet. In particular, it is important to keep enough airflow to always cause impurities. It is known in the prior art vacuum cleaner insoles, such as that disclosed in FR2965165. In return, this system has the particular disadvantage of not being adapted to effectively suck impurities housed in certain types of carpets. An object of the present invention is to meet the drawbacks mentioned above and in particular, first of all, to provide a sole sucker sucker which allows to suck effectively impurities housed in a carpet or carpet. For this purpose, a first aspect of the invention relates to a suction nozzle sole comprising: at least one suction channel of the floor, a front plate having, in a section along a plane normal to the suction channel, a length between 3.5mm and 4.5mm and arranged in front of said at least one suction channel, - a rear chamfer arranged behind the suction channel, characterized in that the rear chamfer has, in said section, a 25 length between 6 and 7 times the length of the front plate. Such a squeegee sole makes it possible to limit its penetration into the carpet or carpet, in order to guarantee a correct suction flow rate, while limiting the thrust and especially the traction forces to be exerted by the user on the nozzle (via suction tube of the vacuum cleaner). In particular, this profile for the sole of the squeegee is well suited for a vacuum cleaner whose suction flow rate is up to 30 liters per second, passing through an orifice diameter 5 of 40 millimeters on a standard box according to IEC 312. It is referred to a plane normal to the suction channel, one could also use a plane perpendicular to the ground sucked and oriented in the longitudinal direction of suction (that is to say, in the direction front-rear suction ).
    [0002] Advantageously, a rear plate is arranged between said at least one suction channel and the rear chamfer, the rear plate having, in said section, a length 4 to 6 times smaller than the length of the front plate. Such a rear plate limits the efforts to exert to push the nozzle forward, because the rear chamfer does not fall directly into the suction channel. Advantageously, the rear plate is connected to the rear chamfer by a radius of between 10mm and 15mm. This implementation limits the friction of the sole on the carpet or carpet. Advantageously, the front plate defines a base plane, and the rear chamfer is inclined, relative to the base plane, by an angle ranging from 10.5 ° to 14.5 °. This implementation makes it possible to guarantee limited friction during backward movements, while having a correct suction flow rate. Advantageously, the squeegee sole comprises a front chamfer, the front plate is arranged between said at least one suction channel and the front bevel, and the front bevel is inclined, relative to the base plane, by an angle ranging from 13 ° to 17 °. This implementation ensures a limited friction during forward movements, while having a correct suction flow. Advantageously, the squeegee sole comprises a connecting radius between the front chamfer and the front plate between 7mm and 13mm. This implementation limits the friction of the sole on the carpet or carpet.
    [0003] Advantageously, the front chamfer has, in said section, a length of between 3.5 mm and 7.5 mm. This implementation ensures a limited friction during forward movements, while having a correct suction flow. Advantageously, there is provided a radius of attack arranged in front of the squeegee sole and between 3.5mm and 8.5mm. A second aspect of the invention is a vacuum cleaner comprising a squeegee sole according to the first aspect. Advantageously, the vacuum cleaner comprises a suction tube connected to the nozzle by means of a connecting rod, and the connecting rod is embedded in one of the suction tube or the nozzle. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawing, in which: Figure 1 shows a section of a vacuum cleaner comprising a soleplate according to the present invention. Figure 1 shows a section of a vacuum cleaner, which shows a suction channel 10 which opens into the lower part of the vacuum nozzle, otherwise called sole (part of the vacuum cleaner nozzle called to be in contact with the soil to be cleaned). The section shown in Figure 1 is made in a plane normal to the suction channel 10, that is to say that it is a normal ground plane to be cleaned, and aligned with the front-rear direction of the vacuum cleaner (in other words, the cleaning direction). 3035583 - 4 - The sole comprises in front (that is to say on the left in Figure 1) of the suction channel 10 a front plate of a length L1, including 3.5 and 4.5 mm, and advantageously, included between 3.5mm and 4.4mm. Back of the suction channel 10, the sole comprises a rear chamfer of a length L2 which is 6 to 7 times longer than the length L1 of the front plate. As a result, the rear chamfer has a length L2 between 21mm and 31.5mm, and more preferably, the length of the rear chamfer is between 26mm and 30mm. Between the rear chamfer and the suction channel 10, there is a rear plate 10, of a length L 3 which is 6 to 7 times smaller than the length L 1 of the front plate. Accordingly, the rear plate has a length L3 between 0.6mm and 1.1mm, and more preferably, the length of the rear plate is between 0.7mm and 0.9mm. The front plate can serve as a basic plan for defining the inclination of the rear chamfer, and this inclination al is between 10.5 ° and 14.5 °. It is possible to provide a connection radius RI between the rear plate and the rear chamfer, and advantageously, this connection radius RI has a value of between 10 mm and 15 mm. At the front of the suction channel 10, the front plate is arranged between the suction channel 10 and a front chamfer with a length L4 of between 3.5 mm and 7.5 mm. The front chamfer is connected to the front plate by a connecting radius R2 with a value between 7mm and 13mm. Finally, a driving radius R3 of a value between 3.5 mm and 8.5 mm can be provided. Finally, the front chamfer is inclined, relative to the base plane, by an angle a2 ranging from 13 ° to 17 °. In other words, the portion of the squeegee sole has, in front of the suction channel 10, a length L5 which is between 1.7 and 2.1 times smaller than the length L6 of the part of the sole behind the Advantageously, the length L5 is between 13.9mm and 17.9mm, and the length L6 is between 27.7mm and 31.7mm. This arrangement of the sole (which is in contact with the ground to be cleaned, that is to say with the fibers of a carpet or carpet) allows the nozzle 5 to maintain a flow rate sufficient to suck effectively impurities that would be in the fibers of a carpet or carpet. In other words, the shape of the sole allows the suction nozzle not to sink too much into the carpet or carpet, which limits the pressure loss of the air flow that passes through the carpet fibers or carpet.
    [0004] It may also be noted that the vacuum nozzle in question is connected to a suction tube via a connecting rod, which is pivotable only with respect to the nozzle, being recessed on the suction tube. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment of the invention described herein without departing from the scope of the invention defined by the appended claims.
