    [0001] TECHNICAL FIELD The present invention relates to the field of pool equipment. It relates more particularly to a swimming pool cleaning device whose debris filter is extractable from a side face of the body of the device. STATE OF THE ART The invention relates to a surface cleaner device immersed in a liquid, such as a surface formed by the bottom and the side walls of a pool, in particular a swimming pool. More specifically, the invention refers to a mobile pool cleaning robot. Such a robot performs the cleaning of the pool by browsing and brushing the surface of said pool, and sucking any debris to a filter adapted to collect said debris. Debris means all the particles present in the basin, and having a surface or volume measurement within a certain range whose lower and upper limits are a function of the technical characteristics of the robot, so that, on the one hand, the upper limit allows the entry of said particles into the filter device, and on the other hand, the lower limit prevents the output of said particles from the filter device. It is, for example, pieces of leaves, microalgae, etc., these debris being normally deposited at the bottom of the basin or glued on the side walls thereof. Most commonly, the robot is powered by an electrical cable connecting said robot to an outdoor control and power unit. Currently, there are different immersed surface cleaners, including removable and removable filter device. Thus, EP 2,235,293 and EP 2,235,296 describe apparatuses conventionally comprising a body, drive members of said body on the submerged surface, a filtration chamber formed within the body and comprising a liquid inlet, an outlet of liquid, a hydraulic circuit for liquid circulation between the inlet and the outlet through a filtering device. In addition, in the cleaning apparatuses described in these documents, the filtering device is removable and extractable from the body of the apparatus by means of a hatch arranged on an upper wall of the body of said apparatus, so that the sheets and other debris can be emptied without having to return the cleaning device.
    [0002] These devices have automatic programs for cleaning the bottom of the basin and possibly the side walls thereof. Such a program determines a cleaning of the pool in a predetermined time. Generally, the robot is removed from the water by the user at the end of the cycle or at regular intervals, when the filter can no longer perform its functions due to too much debris (leaves, microparticles, etc.). ) and needs to be cleaned. In recent models, the robot's external control and power unit emits a light signal when this filter cleaning operation is to be performed. The action of cleaning the filter by the user requires the latter to take the robot out of the pool to extract the filter housed within his body, then to empty the filter and finally to wash it with large water, for example by means of a garden hose. These operations are potentially messy for the user insofar as the risk of contact with debris and filtration sludge is not negligible. These cleaning operations therefore constitute 20 for the user a source of inconvenience. In addition, the filtration performance of the apparatus also depends on the capacity of the hydraulic circuit and the geometry of the internal components to generate vortex movements of liquid within the filter device. In current models of cleaning apparatus, the configuration and position of the filtration device, with respect to the entire hydraulic circuit, does not optimize the appearance of such swirling movements. Indeed, when it enters the filtering device, the flow of liquid sees its movement stopped by various physical obstacles such as straight walls, thus preventing the liquid from continuing naturally its course and create swirling movements. Furthermore, in current cleaning devices, the arrangement of the filter device with respect to the hydraulic circuit requires the liquid to be conveyed either from the side or the top of said filtering device. Consequently, when it is in operation, the cleaning apparatus embeds a quantity of water that is very much greater than that actually contained in the filtering device. This excess of liquid mass has a direct effect on the weight of the cleaning robot making it difficult to extract the pool.
    [0003] SUMMARY OF THE INVENTION The object of the present invention is to remedy all or some of the disadvantages of the prior art, in particular those set out above, by proposing a solution which makes it possible to have swimming pool cleaning devices comprising a body whose filter is extractable by a lateral face of said body and shaped so as to encourage the creation of swirling movements, to be easily cleaned by a user, and arranged so that the total water weight embedded in said apparatus is optimized by so as to facilitate the extraction of the pool.
    [0004] To this end, the invention relates to an apparatus for cleaning a surface immersed in a liquid, in particular a pool cleaning robot, comprising a body, said body having lower, upper and side walls configured so that: said bottom wall is intended to be positioned facing the submerged surface on which the apparatus is moving, - said upper wall is opposite to said bottom wall, - said side walls connect said lower and upper walls, means for displacing the body on said immersed surface, a central chamber, located inside the body, and comprising a filtering basket, said filtering basket having a filtering wall, and an opening for extracting said filtering basket from the body . In addition, said opening is arranged on a side wall of the body. In particular embodiments, the cleaning apparatus 30 includes one or more of the following features, taken alone or in any technically possible combination. In a particular embodiment, said side walls comprise right and left side walls positioned respectively on the right and the left of the apparatus when said apparatus moves forward, said opening being of cylindrical shape and arranged on said right or left side wall. In a particular embodiment, the filtration basket comprises a lid mounted hermetically on said filter basket. In a particular embodiment, the lid is removable from said filter basket. In a particular embodiment, the lid comprises gripping means adapted to allow the extraction of the filter basket 10 from the body. In a particular embodiment, the lid comprises locking means with the body adapted to prevent the unwanted extraction of the filter basket. In a particular embodiment, the filtering wall of the filter basket (151) has a filtering side face (153) arranged facing the cover (17).

PRESENTATION OF THE FIGURES The characteristics and advantages of the invention will be better appreciated thanks to the description which follows, a description which sets out the characteristics of the invention through preferred embodiments, which are in no way limiting thereto. The description is based on the appended figures which represent: FIG. 1: a 3/4 front view of an exemplary embodiment of a pool cleaning robot. - Figure 2: a rear view of a 3/4 embodiment of a pool cleaning robot. FIG. 3 is a side view of an exemplary embodiment of a filtration basket adapted to the cleaning robot of FIGS. 1 and 2. In these figures, identical references from one figure to another designate elements. identical or similar. For the sake of clarity, the elements shown are not to scale unless otherwise stated. DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION The present invention finds its place in a swimming pool technical environment, for example a family-type buried pool. Such a pool includes in particular walls constituting a submerged surface. Fig. 1 and Fig. 2 show an exemplary embodiment of a pool cleaning robot (10), and correspond to front and rear views respectively of said robot (10). The pool cleaning robot (10) is intended to be supplied with current and controlled by a power supply and control box (not shown in Figures 1 and 2). Said power supply and control unit is positioned outside the pool, and comprises a power supply card 20 adapted to transform an alternating current, from the electrical mains, into direct current necessary for the operation of the cleaning robot (10). , and an electronic control board adapted to provide automated management of movements of the cleaning robot (10) on a submerged surface. In an alternative embodiment, the cleaning robot (10) embeds said electronic control board, the latter being arranged, for example, near an engine of said cleaning robot (10). In a particular embodiment, said power supply board of the power supply and control unit is adapted to convert a 230 volts (V) voltage AC current from the electrical mains to a DC current of less than 30 V. pool cleaning robot (10) is supplied with electrical energy by means of a sealed flexible cable (200) connecting the robot (10) to the power supply and control cabinet. The pool cleaning robot (10) comprises a body (11) as well as means for moving the body (11) on the immersed surface, said moving means being driven by a motor.
    [0006] In addition, said body displacement means (11) comprise driving and guiding means (12) of the body (11) on the submerged surface. In the nonlimiting example illustrated in FIGS. 1 and 2, the driving and guiding members (12) comprise four wheels (121) and tracks (122) arranged on either side of the body (11). . More particularly, said wheels (121) form two groups of two wheels arranged laterally with respect to the body (11). The axes of rotation of said four wheels (121) belong to a single plane, and each wheel of one of said two groups being positioned opposite a single wheel of the other of said two groups so that they have the same axis of rotation. In addition, the motor driving said driving and guiding members (12) is fed via an on-board electronic card as described above. Nothing precludes, according to other examples not detailed herein, having a different number of wheels (121) as well as other configurations for the driving and guiding members (12). For the remainder of the description, an axis Z relative to the cleaning robot (10) is defined. Said axis Z has a direction normal to the immersed surface on which the driving and guiding members (12) rest when the robot (10) is in operation, and is oriented from said immersed surface 25 towards the body (11). , it being understood that the direction of upward movement corresponds to the orientation direction of the Z axis. Said Z axis is represented, by way of non-limiting example, in FIGS. 1 and 2. In the following description the convention is adopted that a normal to the wall of any object is always oriented from the inside to the outside of said object. Moreover, we restrict the definition of the parallelism of two lines in the dimension space 3 in the case where there exists a single plane containing the two said lines, so that the two said lines are parallel, in the sense of the definition 3036126 7 of the definition usual parallelism in the dimension space 2, in the said plane. By induction, such a restriction also applies to any element of dimension 1 comparable to a half-line or a segment. For the rest of the description, two X and Y axes are also defined such that: the X axis is longitudinal, defined as the axis of movement of the cleaning robot (10) on the immersed surface, when the driving and guiding members (12) are controlled by the power supply and control box to move in the same direction, and oriented in the forward direction, i.e. here from right to left in relation to FIGS. 1 and 2, the Y axis is said to be transversal and defined so that the three-dimensional coordinate system XYZ is orthogonal direct. Therefore, the Y axis is parallel to the axis of rotation of the wheels. It is therefore understood that, because of its dependence on the position of the cleaning robot (10) on the immersed surface, said XYZ mark is a movable mark. The notions of front, back, left, right, up, down, up, down, etc. relating to the cleaning robot (10) are defined relative to the XYZ mark.
    [0007] Finally, a wall of any object is seen as a continuum of material points. Therefore, for the remainder of the description, the notion of minimum / maximum coordinate of a wall, according to any one of the directions X, Y or Z, is defined as the minimum / maximum coordinate, according to said any one of X, Y or Z directions, said material points 25 defining said wall. The body (11) of the cleaning robot (10) has lower, upper (111) and lateral walls configured so that: - said bottom wall is intended to be positioned facing the immersed surface on which said robot moves ( 10), said top wall is opposed to said bottom wall, said side walls connect said bottom and top walls. One of the side walls of the body (11) is called "front wall" (114).
    [0008] The said front wall (114) is configured such that none of its normals is parallel to the Y axis, and such that its minimum coordinate in the X direction is greater than the maximum coordinate in the X direction of the side walls. other than said front wall (114).
    [0009] In addition, one of said side walls of the robot (10) has an opening (113) adapted to allow the extraction of a filter basket (151) from the body (11). Said opening (113) comprises a peripheral edge delimiting its surface, said edge being a closed curve entirely comprised in said side wall.
    [0010] Said filter basket (151) will be described in more detail hereinafter. In the nonlimiting example illustrated in FIGS. 1 and 2, the body (11) has a generally parallelepiped shape so that the bottom and top walls are orthogonal to the axis Z. The assembly formed by the side walls comprises a single left side wall (112) orthogonal to the Y axis, and positioned on the left of the robot (10) when said robot (10) moves forward. In addition, the opening (113) is arranged on, and integral with, said side wall (112) and is circular in shape. The body (11) also comprises a front wall (114) of rounded shape and configured so that any normal vector of said front wall (114) is contained in a plane orthogonal to the Y axis. Nothing excludes, following other non-detailed examples, to have other forms for the opening (113), such as for example triangular, as well as for the front wall (114). Moreover, nothing also precludes the opening (113) from which the filter basket (151) is extractable from being arranged on a side wall positioned on the right side of the cleaning robot (10) as it moves. forward. The body (11) of the pool cleaning robot (10) comprises a cleaning brush (13) adapted to clean the immersed surface on which said robot (10) moves. By "cleaning the immersed surface" is meant here to transmit a movement to the debris encountered by the cleaning robot 30 (10) during its movements on said immersed surface. Said movement is effected in a direction opposite to that of the advancement of the robot (10), of said immersed surface towards the bottom of the cleaning robot (10), that is to say in the direction of the lower wall of said robot (10) where the debris is then sucked. In the nonlimiting example illustrated by FIGS. 1 and 2, the convex envelope of the cleaning brush is cylindrical in shape, of axis of rotation coincides with that of the front wheels of the robot (10), and of width equal to the distance, along the Y axis, between the front wheels of the robot (10). The cleaning brush (13) comprises a central tube of cylindrical shape, as well as brushes arranged radially and uniformly all along the surface of the tube. The brushes are flexible, generally parallelepipedic in shape, and adapted to rub the immersed surface so that the debris is driven toward the lower wall of the body (11). According to other non-detailed examples, nothing excludes having other geometries as well as other positions, relative to the body (11) of the cleaning robot (10), for the cleaning brush (13). as well as brooms. The pool cleaning robot (10) has a filter device adapted to filter debris entering the body (11) from below the robot (10). For this purpose, said filtration device comprises a hydraulic circuit comprising a plurality of inlets (not shown in FIGS. 1 and 2) and liquid outlets, and is adapted to allow the circulation of the liquid from at least one of said inlets. liquid to at least one of said liquid outlets. More particularly, said liquid inlets are positioned upstream of the hydraulic circuit and pass right through the bottom wall of the body (11). In other words, the debris, not yet filtered, enter the robot (10) passing through said liquid inlets.
    [0011] Said liquid outlets, for their part, are of different types. First, one of said liquid outlets is an upper opening (141) positioned downstream of the hydraulic circuit and passing right through the upper wall (111). Said upper opening (141) is adapted to discharge, outside the cleaning robot (10) in operation and in a direction substantially parallel to the Z axis, the liquid discharged from its debris because of its circulation within the filtration device. In a preferred embodiment, illustrated by FIGS. 1 and 2, but in no way limiting, the opening (141), circular in shape, is positioned on the top wall (111) at the rear of the robot. (10). In addition, fins (143) are disposed across said opening (141) all along its circumference. Such a configuration is advantageous insofar as the fins (143) make it possible to straighten the hydraulic flow in a purely vertical movement along the axis Z. Thus, when the cleaning robot (10) is in operation, the clean water , that is to say having been filtered in the filtration device, is sucked by means of a motor described below to said opening (141), the fins (143) having the role of straightening the flow of this clean water along the axis Z. In a secondary manner, said fins (143) also prevent, on the one hand, the entry of objects through the opening (141) of the upper wall (111), and on the other hand, the introduction of the hands of a user into the hydraulic circuit, thus preventing any risk of damage to the filtration device or even physical damage for said user.
    [0012] Moreover, said liquid outlets are also front openings (142) passing right through the front wall of the robot (10), and adapted to evacuate the clean water contained in the body (11), when the robot ( 10) is no longer in operation and is removed from the pool by a user. In the nonlimiting example illustrated in Figures 1 and 2, the hydraulic circuit 20 has two circular openings (142), each of said front openings (142) having a uniformly partitioned surface into four smaller openings. Nothing excludes, according to other non-detailed examples, other shapes and configurations for the front openings (142).
    [0013] In the remainder of the description, unless otherwise stated, the following applies in a nonlimiting manner in the case where the pool cleaning robot (10) comprises, when it is in operation, a single liquid inlet at its level. lower wall and a single liquid outlet (141) at its upper wall (111).
    [0014] The body (11) of the pool cleaning robot (10) also comprises a motor and a propeller, the assembly formed by said motor and said propeller constituting a pump adapted to suck, and to be moved, the liquid in the hydraulic circuit of the filtration device. Said pump 3036126 11 is positioned downstream of the filtration circuit, between the filter basket (151) and the liquid outlet (141), in the upper part of the body (11) of the robot (10). More particularly, said motor is adapted to drive the rotating propeller so that, on the one hand, the debris directed towards the underside of the cleaning robot (10), thanks to the cleaning brush (13), is sucked up. through the liquid inlet in the body (11), and secondly, the filtered liquid, that is to say free of its debris, is expelled to the outside of the robot (10) through the opening (141). The body (11) also comprises valves (115) positioned, from outside the robot (10), on the front wall (114) of said body (11), in the lower position of said wall (114). In addition, each of said valves (115) is located opposite a single front opening (142), so that when the valves (115) are pressed against the front wall (114), they completely cover said openings (142). , thus preventing the exit of the filtered liquid contained in the body (11).
    [0015] More specifically, the impeller of the pump is adapted to create, when rotating, a low pressure flow at the front wall (114), so that the valves (115) are sucked and plated towards said wall before (114), thereby obstructing the front openings (142) to which they face. In this way, when the robot (10) is in operation, the filtered liquid, therefore clean, which is contained in the body (11) can not escape through said front openings (142), and has the sole way of exit the opening (141). It is thus understood that the valves (115) are positioned so as to be in contact only with filtered liquid. Alternatively, when the robot is not running, the pump's propeller is stopped, so that the valves (115) are free from their movement and not pressed against the front wall (114) as this is the case. case when the robot (10) is in operation. In this way, when a user wishes to extract the robot (10) from the pool by pulling it preferably from the rear (which has the effect of tilting the front of said robot (10) towards the bottom of the pool ), thanks to gripping means adapted and integral with one of the walls of said robot (10), the liquid contained in the body (11), at the front wall (114), exerts a pressure, because of the gravity, on the valves (115) which separate from said wall (114), thus leaving the filtered liquid residual in the robot (10) to escape through the front openings (142). Such a configuration reduces the mass of liquid within the robot (10) so that its extraction from the pool is facilitated.
    [0016] In the nonlimiting example illustrated in FIGS. 1 and 2, the valves (115) are two in number and made of rubber. Each valve (115) is positioned opposite an opening (142), and comprises a disk, said disk being the base of a rod positioned along the axis of rotation of said disk. Each said rod is secured to each said disk, and radially crosses the front wall (114) at a hole drilled equidistant from the four small openings partitioning the front opening (142), to which each valve (115) makes face. In addition, the stem of each valve (115) comprises at its end located inside the body (11) a shoulder adapted to serve as a bearing surface of said end against the front wall (114), and than preventing the removal of said valve (115) from said drilled hole. In this way, each valve (115) is adapted to move radially through the front wall (114), at an amplitude corresponding to the distance separating its base from the shoulder of its stem, less the thickness of the wall before (114). Nothing excludes, according to other non-detailed examples, having other geometries for the flaps (115). The filtration device of the pool cleaning robot (10) comprises a central chamber (15) disposed within the body (11). Said central chamber (15) passes right through the body (11) of the cleaning robot (10) and has a transverse wall resting on two lateral faces. Each side face is an integral part of a side wall of the body (11), said side walls being distinct, non-contiguous and different from the front wall (114). One of said lateral faces is virtual, and coincides with the opening (113). The other side face, distinct from the opening (113), is covered by a closed surface (16) positioned on the left side wall (112), that is to say included in the body (11) of the robot (10), and configured so that the liquid, in which the robot (10) is immersed, can not penetrate within the body (11) by said closed surface (16).
    [0017] In the nonlimiting example illustrated in FIGS. 1 and 2, the central chamber (15) is of substantially cylindrical shape, of axis of revolution parallel to the Y axis. The transverse wall of the central chamber (FIG. 15) is based on two virtual disks arranged in facing relation and forming an integral part of two lateral walls orthogonal to the Y axis. One of the two said disks is the base of a porthole having the shape a spherical cap and curved shape facing outwardly of the body (11). Said porthole is said closed surface (16) and is attached by welding, gluing, or any other means to the body (11). In addition, said porthole is made of PMMA type transparent plastic (acronym for "Polymethyl Methacrylate"), so that a user of the pool cleaning robot (10) can acquire visually, by looking at in the body (11) along an axis parallel to the Y axis, a partial information as to the congestion state of the filtration device.
    [0018] The central chamber (15) is interposed on the hydraulic circuit between the liquid inlet and the liquid outlet (141). The central chamber (15) is supplied with liquid by means of at least one upstream channel connecting the liquid inlet to said central chamber (15). More particularly, said upstream channel opens into the central chamber (15) through a feed opening (152), said feed opening (152) being configured so that the liquid which has passed through it is directly conveyed to within the filter basket (151). It is thus understood that only unfiltered liquid passes through said feed opening, from the upstream channel to the filter basket (151), the arrangement of said feed opening (152) with respect to the feed basket. filtration (151) being described in more detail below. In a particular embodiment, the hydraulic circuit of the filtration device comprises a plurality of liquid inlets, and a plurality of upstream channels and feed openings adapted to supply liquid to the central chamber (15).
    [0019] In the remainder of the description, one places non-limitatively in the case where said central chamber (15) is fed by a single upstream channel. FIG. 3 represents an exemplary embodiment of a filter basket (151), said embodiment being adapted to the cleaning robot (10) of FIGS. 1 and 2. The central chamber (15) comprises said filter basket (151), the latter being adapted to filter the debris sucked into the filter circuit by the liquid inlet, and conveyed successively via the upstream channel and the feed opening (152) within said central chamber (15). For this purpose, the central chamber (15) is configured so that its internal volume is greater than that of the filter basket (151), the latter being substantially centered within said central chamber (15). In this way there is a residual space between the filter basket (151) and the central chamber (15), said residual space being intended to contain only liquid having initially passed through said filter basket (151), therefore clean liquid. The clean liquid contained in said residual space is intended to be discharged through the upper opening (141) and the front openings (142) when the robot (10) is respectively in operation and stopped. The filter basket (151) occupies most of the internal volume of the central chamber (15), and generally matches the shape. Thus, said filter basket passes right through the body (11) of the cleaning robot (10), and has a transverse wall supported on two distinct and non-contiguous side faces. In particular, one of the two said lateral faces, called "filtering side face" (153), is situated on the same side of the body (11) as the closed surface (16) of the body (11) of the robot (10), and is in addition directly facing said closed surface (16). The second lateral face (154) is virtual, contained in the opening (113) when the filter basket (151) is inserted into the central chamber (15), and located opposite said filtering lateral face ( 153). Said lateral face (154) comprises a peripheral edge delimiting its surface.
    [0020] Said filtration basket (151) comprises a filtering wall, also called "filter" in the following description, said filtering wall being the meeting of said transverse wall of said filter basket (151) and said filtering side face (153). ). Said filtering wall comprises a fine mesh surface forming the filter itself, and is attached by welding, gluing or any other means on a perforated rigid reinforcement (155). The mesh size of the filter wall is naturally adapted to the size of the particles that the cleaning robot (10) must retain when moving on the immersed surface. Furthermore, the filter basket (151) comprises a non-return valve (156) integrated in the transverse wall of said filter basket (151), so that when said filter basket (151) is inserted into the central chamber (15), said non-return valve (156) is positioned opposite the feed opening (152). Said nonreturn valve (156) is adapted to allow the entry of the liquid, having passed successively in the upstream channel as well as through the opening (152) of the central chamber (15), within the filter basket (151). ), while preventing the output of said liquid from said filter basket (151).
    [0021] The filter basket (151) also has a removable cover (17) hermetically mounted on said filter basket (151) to prevent leakage of debris-laden liquid. For this purpose, said cover (17) has a peripheral edge adapted to cooperate with the peripheral edge of the side face (154).
    [0022] In an alternative embodiment, the cover (17) comprises a peripheral seal (not shown in the figures) bearing on the edge of the lateral face (154). In the nonlimiting example illustrated in FIG. 3, the filter basket (151) is cylindrical in shape, with an axis of revolution parallel to the Y axis and coinciding with the axis of revolution of the central chamber (15). ). The transverse wall of the filtering basket (151) is based on two disks, placed facing each other, and forming an integral part of two lateral walls orthogonal to the Y axis. One of the two said disks is said filtering lateral face ( 153) located directly opposite the body porthole (11). The second disk is the virtual side face (154). Furthermore, said lateral face (154) is the base of a porthole, having the shape of a spherical cap and curved shape facing outwardly of the body (11), said porthole being the cover (17) of the filter basket (151). Said cover (17) is made of transparent solid material 3036126 16 (glass, plastic, etc.), so that a user of the pool cleaning robot (10) can visually acquire, looking within the body (11) along an axis parallel to the Y axis, a partial information as to the congestion state of the filtration device.
    [0023] The lid (17) of the filter basket is removable, thus allowing a user to access the contents of the filter basket (151), to clean the filter when necessary. For this purpose, the cover (17) comprises gripping means (18) for manipulating said cover (17) when it does not cooperate with the filter basket (151), as well as holding means in a fixed position with the filter basket (151). In the nonlimiting example illustrated in FIGS. 2 and 3, said gripping means (18) of the lid (17) are a fixed handle, and said means for holding the lid (17) with the filter basket (151) comprise a protrusion arranged on a restricted portion of the peripheral edge 15 of said cover (17). Said projection is adapted to fit in a groove cut on the transverse wall of the filter basket (151) at the side face (154). In this way, when said projection is embedded in said groove, the cover (17) is held integral with the filter basket (151). Furthermore, the cover (17) is removable from said filter basket (151) by means of a rotational movement for pulling said projection out of said groove. Said rotational movement is performed by a user, according to the axis of rotation of the filter basket (151), by means of said fixed handle (18), and its amplitude does not exceed a quarter of the total circumference of the peripheral edge the side face (154).
    [0024] Furthermore, in the nonlimiting example illustrated by FIGS. 2 and 3, the handle (18) of the lid (17) is a transparent plastic strip having two attachment points on said lid (17), and configured to so that the gap between said handle (18) and the cover (17) allows a user to grip said handle (18) fully. In addition, the two said attachment points are diametrically opposed relative to the lateral face (154) serving as a base for the cover (17). There is nothing to preclude, according to other non-detailed examples, other forms, other configurations, as well as other construction materials for the fixed handle (18).
    [0025] The filter basket (151) is extractable, that is to say it can be extracted from and introduced into the central chamber (15), the cover (17) forming a continuity with the wall lateral body (11) comprising the opening (113). The extraction, or introduction, of the filter basket (151), 5 when it is secured to the lid (17), is done through the gripping means (18) in a translational movement. Said translational movement substantially follows any line joining two points respectively belonging to the faces (153) and (154). In the nonlimiting example illustrated in FIG. 1, the filter basket 10 (151) can be extracted from the central chamber (15) along its axis of revolution, that is to say in a translational movement parallel to the Y axis. Said translational movement is, for example, initiated by a user pulling on the filter basket (151) by means of the handle (18) of the lid (17). In addition, the cover (17) has locking means (20) with the body (11) of the pool cleaning robot (10). Said locking means (20) are connected to the gripping means (18) by return means, and are adapted when the cover (17) is secured to the filter basket (151) by means of the holding means, prevent unwanted extraction of said filter basket (151).
    [0026] In the nonlimiting example illustrated in FIGS. 1, 2 and 3, said locking means (20) comprise a latch (21) positioned at one end of the handle (18) of the cover (17), and a notch (22) molded into the side wall (112) of the body (11). In particular, said latch (21) has a curved distal end adapted to fit into said notch (22) so as to prevent extraction of the filter basket (151) out of the central chamber (15). ). In addition, said return means connecting said latch (21) to the handle (18) is a torsion spring. The torsion spring is configured such that pressure on the proximal end of said latch (21) allows said latch (21) to pivot about the axis of rotation of said spring. In this way, a user can manually operate the latch (21) to extend its distal end of said notch (22), and thus unlock and extract the filter basket (151) from the body (11).
    [0027] In a particular embodiment, the notch (22) is not molded in the outer surface of the body (11), and consists of a part attached by welding, gluing, or any other means, to the side wall. comprising the opening (113).
    [0028] Said filter basket (151) also comprises gripping means (23) positioned on the filtering side face (153), outside the filter basket (151), and allowing the manipulation of said filter basket (151) when extracted from the central chamber (15). In the nonlimiting example illustrated in FIG. 3, said gripping means (23) are a fixed handle disposed on the part of the perforated rigid reinforcement (155) of the filtering lateral face (153) of the filter basket ( 151). Said handle (23) comprises two attachment points on said filtering side face (153), and is configured such that the gap between said handle (23) and said filtering side face (153) allows a user of grasping said handle (23) fully. In addition, the two said attachment points are diametrically opposed relative to the filtering side face (153). Nothing excludes, according to other non-detailed examples, other shapes and configurations for the fixed handle (23). More generally, it should be noted that the embodiments 20 considered above have been described by way of non-limiting examples, and that other variants are therefore possible. BENEFITS OF THE INVENTION The use of a central chamber (15) and a filter basket (151), both of cylindrical shape (as illustrated by Figures 1, 2 and 3), and configured so that said filter basket (151) is extractable from a side face of the robot (10), is advantageous in optimizing debris filtration. Indeed, such a configuration is adapted so that the circulation of the liquid, which enters the filter basket (151) via the upstream channel, in a movement from bottom to top relative to the XYZ mark linked to the robot (10), is cyclonic throughout the 3036126 19 cleaning the pool. Indeed, the relative positions of the supply opening (152) and the non-return valve (156) are adapted so that the liquid enters the filter basket (151) in a direction which follows the shape of the filtered. Such a configuration is advantageous because, because the flow of liquid 5 follows the rounded shape of the filter, it optimizes the formation of swirling movements within a region of the filter basket (151), said region being remote from the edges of said filter basket (151). Such swirling movements make it possible, on the one hand, to unclog debris that can stick to the filtering wall of the filter basket (151), and on the other hand, to keep the suspended debris away from the filtering walls, from so that the filter can not clog. Furthermore, in addition, the filter basket (151) is configured so that it occupies most of the internal volume of the central chamber (15). Such a configuration is advantageous because it makes it possible to limit the loss of space within the robot itself (10), so that the liquid that has not yet been filtered is conveyed directly into the filter basket (151) along a straight path, without traveling a distance on the sides of said central chamber (15). In this way, and on the one hand, the flow of liquid undergoes less pressure losses compared to what can be observed in a conventional robot, and on the other hand the robot (10) carries less liquid than traditional robot. Thus the weight of the robot (10) is optimized, which reduces the energy consumption of the cleaning device. Furthermore, the fact that the filter basket (151) is extractable from a side face of the robot (10), and has gripping means (18) and (23), makes it easy to empty, especially without having to handle the entire cleaning unit. More specifically, the gripping means (23) are configured so that the filter basket (151) is manipulable without having to come into contact with filtration sludge, located at the level of the filtering surface. The user can thus, after extracting the filter basket (151) from the body (11) by means of the gripping means (18), return said filter basket (151) using the gripping means ( 23), empty it, then wash it with large amounts of water still without coming into contact with the filtration sludge. In addition, the cylindrical shape of the filter basket (151) also contributes to easy cleaning of the latter. Indeed, the absence of nook of the internal volume of the filter basket (151) implies the absence of areas 5 difficult to access, and therefore difficult to clean.
