Definitions

• the present invention relates to a vacuum cleaner nozzle having a soleplate, the rim of which has at least one angular zone, and more particularly a nozzle nozzle having a soleplate intended to move over the surface to be cleaned, having an upper face provided with a circuit for air circulation and a lower face provided with at least two removable pads allowing the nozzle to slide on the surface to be cleaned.
• a T-shaped connection removably mounted on the upper face of the sole, makes it possible to connect, via said air circulation circuit, a plurality of suction orifices to a removable tube for evacuating the aspirated waste.
• the invention also relates to a vacuum cleaner comprising such a nozzle.
• the suction nozzles for vacuum cleaners of the prior art generally have shapes and dimensions which make their use difficult, particularly for vacuuming waste located in narrow corners or passages or for vacuuming waste which is on surfaces congested with furniture. .
• the user is forced to change the nozzle of the vacuum cleaner to reach corners or narrow passages, while in the second case, the user is forced to move the furniture in order to position the sole of the squeegee above the waste.
• the object of the invention is to overcome the drawbacks mentioned above by means of a vacuum cleaner nozzle having a soleplate the rim of which has at least one angular zone connecting any two adjacent edges of the nozzle, characterized in that said zone angular comprises at least one orifice intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
• Such a nozzle allows to approach a suction opening as much as possible of the waste located in corners or narrow passages.
• the nozzle is capable of vacuuming the waste located in corners or narrow passages even if the sole of said nozzle is not positioned above this waste.

• FIG. 3 schematically shows a partially exploded perspective view of the upper face of a nozzle according to the invention without cover;
• FIG. 4 schematically shows a perspective view of the underside of a nozzle according to the invention
• 5 shows a side perspective view of the upper face of a nozzle shown in Figure 4

• FIG. 7 schematically shows a vertical sectional view of a sliding shoe fitted to a nozzle according to the invention
• - Figure 8 shows a suction opening of the nozzle according to an alternative embodiment.
• the vacuum cleaner nozzle 2 comprises a sole 4 intended to move parallel to the surface to be cleaned, the edge of said sole has an angular zone 6 connecting two sides of the nozzle and the end is rounded to avoid damaging walls and furniture during cleaning.
• This angular zone is advantageously highlighted in a triangular nozzle as described in the present application, by way of example of embodiment, but the invention can also be applied to a nozzle of any shape, circular with a point which forms said angular zone, but also for a rectangular nozzle then having four angular zones for connecting the edges, located at the four corners of the nozzle.
• said angular zone comprises a front orifice 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
• frontal opening it is meant an opening starting from the sole, where the suction channel is located and extending on the edge of the squeegee. The opening is thus substantially perpendicular to the surface to be cleaned.
• This opening is large enough to be able to vacuum small objects.
• the size of the opening is greater than 0.5 cm 2 .
• the opening is profiled by presenting a leak angle at the base so that the width of the opening at its base is at least twice as much important than its width at half height.
• FIG. 8 shows such an opening 72 having a leak angle 74.
• the width 11 at its base is at least twice as large as its width t2 at mid-height.
• the upper face of said sole 4 is provided with an air circulation circuit 8 while its lower face comprises three removable sliding pads 9 allowing the movement of the nozzle on the surface to be cleaned.
• a T-connection 10, removably mounted on the upper face of the sole 4, makes it possible to connect, via said air circulation circuit 8, a plurality of suction orifices 7, 11, 14 to a removable tube 16 for evacuating the aspirated waste.
• the sole 4 has a substantially triangular shape, the two adjacent sides 18 each of which have a lateral channel 19 open to the surface to be cleaned arranged along the edge of the sole 4.
• each of the lateral channels 19 is connected to a rear channel 20 arranged along the third side 21 forming the rear face of the sole 4, by means of an elbow 22 open towards the surface to be cleaned substantially perpendicular to said side 21 and comprising at least one lateral suction orifice 11.
• the lateral channels 19 communicate with a lower orifice 14 while the posterior channel 20 communicates with two lower orifices 14 situated symmetrically with respect to the middle of said rear side 21.
• These lower orifices 14 are intended to ensure suction of the waste in a direction perpendicular to the surface to be cleaned.
• the air circulation circuit 8 has an H shape having a central groove 32 in which is mounted the duct 34 constituting the horizontal bar of the T connection 10 and two lateral grooves 38 connecting each of the two lower orifices 14 located on the posterior channel 20 to one of the two lower orifices 14 located on one of the lateral channels 19 and to the conduit 34.
• first cover 40 of flat shape and in their middle by a second cover of i-cylindrical shape 42 extending the conduit 34 of the connection in
• each of the lateral grooves 38 of the H-shaped circuit includes a lateral deflector 50 located near the area where the incoming air flows meet through the lower suction orifices 14 located one opposite each other.
• the connection 10 also includes, as can be seen in FIGS. 4 and 6, two central deflectors 52 intended to avoid a frontal collision between the air flows circulating in the duct 34.
• the soleplate 4 In order to avoid impacts between the squeegee and the environment when using the vacuum cleaner, the soleplate 4, as illustrated in FIGS. 2 and 4, is covered on its upper face by a cover 54 made of flexible material also covering the outer edges of the sides 18 and 21 as well as the elbows 22 of said sole 4. Said flexible cover 54 has in its middle a hole allowing the passage of the connection 10 to secure the tube 16. Note that the cover 54 essentially has an anti-shock function insofar as the air circulation circuit 8 is completely covered by the covers 40, 42 and therefore the squeegee can suck up the waste even when this cover 54 is removed from the face upper of the sole.
• the removable pads 9, shown diagrammatically in FIGS. 4 and 7, have a lower surface 60, having a profiled leading edge 62, and are provided with a pad.
• central unit 64 ensuring contact with the surface to be treated when the device is moving.
• Said central pad 64 can be made of PTFE (polytetrafluoroethylene) or any other material having good abrasion resistance and a low coefficient of friction.
• the upper face 66 of said pads 9 is provided with a central ring 68 surrounded by an annular seal 70 intended to absorb vibrations when the nozzle moves on an uneven surface.
• the sliding pads are arranged in the sole so as to raise the nozzle from the surface to be cleaned.
• the distance separating the squeegee from the ground which can be compared to ground clearance, by analogy with the automotive field, makes it possible to establish a synergy between coarse suction through the opening (s) 7, 11 and fine suction through the sides of the squeegee.
