Definitions

• the present invention generally relates to a vacuum nozzle with a hatch access to a motorized brush.
• vacuum suction nozzles such as that described in the document FR 1 1 5871 1, wherein the disclosed nozzle comprises a bottom flange which comprises at least one open suction channel towards the ground and which converges from an outer edge of the sole to a suction port connected to the vacuum cleaner.
• the disclosed nozzle is triangular and in a variant it may include a motorized brush.
• this system has the disadvantage of having no protection element of the motorized brush which is thus directly in contact with the ground. In this case, it is found that when the nozzle is used in particular configurations it may be that the motorized brush is damaged when an element comes into contact with the rotating shaft of the brush.
• the document GB2413942 has meanwhile a nozzle with a hatch access to a motorized brush.
• the motorized brush fits behind this hatch and when using the nozzle, the hatch allows to some extent to protect the motorized brush.
• the advantage of such a structure is that the shaft of this brush is protected by the hatch and the risk of degradation is limited.
• the disadvantage of such a system is that the suction qualities of the nozzle are degraded in favor of the safety of the motorized brush.
• the flange of the hatch is substantially flat which implies that all the air is sucked by the suction port integrated in the hatch. In this case, there is no control of the air velocities towards the inside of the nozzle.
• An object of the present invention is to meet the disadvantages of the documents of the prior art mentioned above and in particular, all firstly, to propose a suction nozzle in which a removable motorized brush is protected and accessible to a user and this without the suction qualities are degraded.
• a first aspect of the invention relates to a vacuum cleaner which comprises a sole.
• the soleplate has at least one suction channel open to the ground and the suction channel converges from an outer edge of the soleplate to a suction port in aeraulic connection with a vacuum cleaner.
• the sole comprises a removable hatch which comprises on the one hand the suction port and on the other hand at least one suction channel open towards the ground and arranged vis-à-vis said at least a suction channel of the sole.
• the vacuum nozzle comprises a cavity open towards the ground, and the hatch is arranged on the cavity, which means that the hatch can cover at least partially the cavity.
• a particularly interesting embodiment consists in that the trap completely covers said cavity. In this case, the area of the hatch is equal to the area of the cavity which is directed towards the ground.
• the hatch of the vacuum cleaner comprises a hooking device for holding said hatch on the soleplate.
• the hooked device of the hatch is a system of clips. This hanging device has the advantage of handling the hatch quickly. The user can quickly remove the hatch to access the cavity, or quickly put it back to isolate the cavity.
• the suction nozzle is substantially triangular with a point directed in the direction of displacement of the nozzle.
• a user manipulates the nozzle, it can move it in all the directions of the ground but there is a preferred direction of displacement which is in general that given by the architecture of the wheels.
• the preferred direction of movement is given by the bisector of the triangle formed by the nozzle. In this way, the tip of the nozzle is directed in the direction of movement of the nozzle.
• the longitudinal axis of the hatch is substantially perpendicular to the direction of movement of the nozzle.
• the vacuum nozzle comprises a removable motorized brush.
• This motorized brush can be removed by a user for maintenance purposes of brush change or even cleaning thereof.
• this brush may have different shapes and different means of rotation.
• the vacuum nozzle has wheels which define a ground clearance of the sole. In other words, the nozzle, and therefore the lower sole of the nozzle, is positioned at a predetermined height of the ground by the wheels. Casters are added under the nozzle at the sole.
• a second aspect of the invention is a vacuum cleaner comprising at least one nozzle according to the first aspect of the invention.
• FIG. 1 shows a nozzle according to the invention seen in perspective from above;
• FIG. 3 represents a view in perspective and from below of the suction nozzle
• FIG. 1 represents a suction nozzle 1 which comprises a sole 14 and wheels 2 whose profile of a tread 15 is barrel-shaped and which defines a ground clearance of the sole 14 when the nozzle 1 rests on a smooth floor. At least two rollers 3 are also arranged under the sole 14.
• the nozzle 1 is in the general shape of a triangle and a point 30 of the triangle is positioned in the direction of movement of the nozzle 1.
• a sealing lip or flap 4 there is disposed around the soleplate 14 a sealing lip or flap 4.
• This sealing flap 4 removes leaks between the smooth floor and the sole 14, and to have a good efficiency suction, the sealing strip 4 is perforated facing the channels 10 of the sole 14, so that the air sucked under the sole 14 can only enter directly into the channels 10 of the sole 14. It in This results in good suction of impurities from the ground because the air velocities in the channels 10 of the soleplate 14 are maximum, since all the air sucked there passes.
• the wheels 2 position in height the nozzle 1 relative to the ground.
• FIG. 2 shows the soleplate 14 on which there are a plurality of suction channels open towards the ground and the suction channels converging from an outer edge of the soleplate 14 to a suction orifice 9 in aeraulic connection with a vacuum cleaner (not shown).
• Aeraulic connection means that the air flow that converges in the orifice 9 suction is then sucked through a hose (not shown) connected to the suction and filtering system of the vacuum cleaner.
• at least one of the channels 10 opens into the tip 30 of the nozzle 1.
• the nozzle 1 comprises a hatch 13 which is substantially in the same plane as the sole 14.
• This hatch 13 comprises the suction port 9 and suction channels 20 open to the ground .
• These suction channels 20 are arranged vis-à-vis the suction channels of the sole 14 in order to maintain the suction flow.
• the channels 20 of the hatch 13 and the channels 10 of the sole 14 have their contiguous parts which have a substantially similar profile.
• the channels 20 of the hatch 13 and the channels 10 of the sole 14 have substantially the same diameter over their entire length. This is to create a regular passage channel that allows the flow of air through not to experience a sudden change in flow.
• the diameter variation does not vary by more than 5 percent. . Thanks to this device, the quality of the suction is maintained.
• this flap 13 is removable and can be removed from the flange 14.
• This flap 13 is substantially rectangular and comprises a hooking device.
• this hooking device consists of mechanical clips consisting on the one hand of pins 7 and on the other hand of grooves 6.
• Such a device allows a user to remove the hatch 13 without the aid of handling tools such as screwdrivers or Allen keys.
• Such a device therefore has the advantage of quickly removing the flap 13.
• the user performs a simple mechanical pressure at the lugs 7 which has the effect of releasing them from the grooves 6 and maintaining the power remove the hatch 13.
• the reverse operation is also fast since it is sufficient for the user to slide the lugs 7 in the grooves 6 provided for this purpose and then apply a low pressure on the hatch 13 at these lugs 7 so that the hatch 13 remains held by these clips.
• this cavity 21 has substantially the shape of a rectangular parallelepiped and has its longitudinal axis which is substantially perpendicular to the direction of movement of the nozzle 1.
• the longitudinal axis of the hatch 13 corresponds to the axis which runs from one end to the other of the hatch 13 and which extends in the direction of the length.
• the direction of movement of the nozzle 1 represents the direction in which a user uses the nozzle 1 in a normal mode of use on a floor.
• the tip 30 of the triangular nozzle 1 is oriented in the direction of movement of the nozzle 1 when used in a normal mode of use.
• a brush 8 is visible in Figure 4 and in the context of the invention, the brush 8 is motorized and is removable. This brush is inserted into the cavity 21 and is held therein by a hooking device.
• This hanging device can be of different types and in the context of the invention it consists on the one hand, and on a first side of the brush, a groove 12 and on the other hand, and the other side of the brush, a bayonet system 1 1. This bayonet system 1 1 makes it possible to rotate the brush 8 when the system for rotating the brush (not visible) is active.
• the vacuum cleaner creates a flow of air which is sucked into the channels 10 towards the suction orifice 9.
• the nozzle 1 comprises the motorized brush 8 protected by the hatch 13 as described above
• the flow of air first passes through the channels 10 and then the channels 20 to arrive in the orifice 9 d suction.
• the addition of a hatch 13 protecting the brush 8 allows through the channels 20 of the hatch 13 to maintain a constant suction flow and not to reduce the quality suction.
