- the cleaning robot according to the invention essentially comprises a head 1 movable in rotation about an axis 4 perpendicular to the ground
- a support 2 which has no functional organ involved in the propulsion of the robot or the suction of the waste, but serves as a support for movement and facilitates changes of direction of the robot.
- the support 2 comprises a support structure comprising for example a set of arms 21 arranged in a star and each carrying at their outer end a sliding member or bearing 22 such as a swivel caster.
- the steerable rollers 22 are arranged in a curve, such as a circle, located outside the curve delimiting the periphery of the head 1 mounted free to rotate about a central bearing defining the axis of rotation 4 of the head 1 relative to the support 2.
- the number of steerable rollers 22 (for example five) and the distance thereof from the axis of rotation 4 are determined so that straight segments connecting two neighboring rollers are located outside the curve defining the periphery of the head 1.
- the reference 23 designates a wheel flange 22.
- the support 2 is connected to the head 1 by a central bearing comprising rolling members 40, such as balls made for example of polyacetal, trapped between a cylindrical inner ring 14 secured to the head 1 and an outer ring 41 which may also have a cylindrical profile, which is integral with the support 2 ( Figure 2).
- rolling members 40 such as balls made for example of polyacetal
- the central bearing whose rings 14, 41 can also be made of a material such as polyacetal, can have a very simple shape, with a single row of balls 40, and defines an opening 13 of communication between the bottom 12 of the head 1 and a space located under a plate 15 secured to the lower portion of the inner ring 14 of the central bearing.
- a receptacle 7 can be removably attached to the plate 15 and can be fixed around the periphery thereof by removable fasteners 71 such as clips or latches.
- the height of the receptacle 7 is determined in such a way that a space is provided between the floor 100 and the bottom of the receptacle 7 when the robot rests on the floor 100 by means of its rollers 22.
- An opening 72 closed by a flexible valve 73 is formed in the central portion of the bottom of the receptacle 7, which may be slightly recessed relative to the periphery of the receptacle 7 ( Figure 2).
- the aspiration of the waste is effected by the opening 72 which is in the extension of the opening 13 of the bottom of the head 1, centered on the axis 4.
- a filter 70 is disposed at the upper part of the receptacle 7 and can be maintained by a frame 16 attached to the plate 15.
- the waste storage receptacle 7, removably mounted on the plate 15 to be easily emptied, is secured of the head 1 when the robot is operating in a pool of liquid, and thus rotates in the same way relative to the support 2 around the bearing centered on the axis 4 which is perpendicular to the ground 100 when the robot rests on its wheels 22.
- Figure 13 shows an example of a particular valve 73 that can be advantageously used in the context of the present invention.
- the shutter valve 73 of this opening 72 may comprise two parallel lateral arms 75, each having a free end fixed by an actuator member.
- the other ends of the arms 75 are attached to a central portion 76 whose surface is slightly greater than that of the opening 72 so as to cover this entire opening 72 in a sealed manner.
- central 76 attached to the arms 75 on the opposite side to the fixing points 74 is a cantilevered tongue whose free end is located between the anchoring points 74 of the lateral arms 75.
- the valve 75 of elastic material such as rubber is plated so as to close the opening 72.
- the valve In the presence of a depression created inside the receptacle 7, the valve is raised
- the central portion 76 cantilevered relative to the raised portions of the arms 75 opposite the hinge points 74 itself has a twist with respect to these raised parts of the arms. 75 and thus raises as a whole parallel to the bottom 77 of the receptacle 7, releasing the opening 72 on all sides and allowing the dirt sucked to come accumulate in the receptacle homogeneously on all sides around the opening 77.
- the head 1 of the robot of FIGS. 1 to 3 will now be described in more detail.
- the head 1 which may be made of molded plastic, comprises upper and lower plates 12 and a side wall 11. embodiment of Figures 1 to 3, the head 1 has a symmetrical shape and the side wall 11 defines a nozzle 18 with a convergent inlet 181 connected to a circular portion centered on the axis of rotation of the head 1, and an outlet 180 ( Figure 3).
- the nozzle 18 is thus perpendicular to the axis of rotation 4, but is not eccentric with respect to this axis of rotation.
- a balancing mass 17 constituted for example by a foam may be attached on either side of the nozzle 18 to the rear part of the head 1.
- a device 30 for injecting water under pressure is disposed in a plane containing the axis of the nozzle 18 and comprises a channel 31 extending along the axis of rotation 4, and connected by a nozzle 3 to a hose pressurized water supply which is provided with one or more rotating joints and one or more floats.
- the fact that the water supply pipe arrives in the axis of the nozzle ensures that the movements of the pipe do not disrupt the movement of the robot and in particular do not change the direction of the propulsion force. The traction exerted on the pipe is thus directly absorbed by the thrust and does not cause parasitic path deviation.
- the pressurized water injection device 30 advantageously comprises a vertical slot 33 placed in the axis of the nozzle 18 in front of the flared entry 181 of the latter to direct a jet of liquid rearwardly parallel to the nozzle. the axis of the nozzle 18 ( Figure 2).
- the vertical duct 31 of the injector 30 is advantageously closed at its lower part by a plug provided with a beveled portion 32 which penetrates inside the duct 31 and allows the jet exiting through the vertical slot 32 to orientate itself. more easily along the axis of the nozzle 18 with a uniform distribution of the flow in the injection slot 33.
- the injection device 30 may be made of a plastic material such as polyacetal for example. The injection device 30 can thus have an easy form to manufacture while producing at the inlet of the nozzle 18 a flat jet having a large driving surface which makes the suction phenomenon more efficient without impairing the propulsive force. .
- a free space is provided between the device 30 for injecting water and the flared inlet 181 of the nozzle 18 to create a venturi effect suction current to the head 1 through the opening 13 formed in the bottom 12 of this head 1.
- a flow of liquid loaded with dirt enters the robot through the central orifice 72 formed in the bottom of the receptacle 7, the flexible valve 73 being lifted under the effect of the suction created by the outlet flow of the injector 30 at the free space between the injector 30 and the inlet 181 of the nozzle 18.
- the flow of dirty liquid is sucked along the axis 4 towards the opening 13 of the head 1, but because of the presence of the filter 70, only the cleaned liquid waste that it transports is drawn into the head 1 towards the nozzle 18 by the depression created at the inlet thereof, to be ejected at the rear of the nozzle 18 together with the pressurized liquid injected by the slot 33 of the injection device 30.
- the waste and dirt are stopped by the filter 70 and accumulate in the peripheral part of the receptacle 7.
- the injector 30 and the nozzle 18 thus constitute both a propulsion device by reaction (by the reaction of the jet of water escaping from the nozzle parallel to the ground 100), which moves the robot in the bottom of the nozzle. the pool and a device for creating a depression in the head 1 allowing suction of the waste through the suction port 72, the suction produced by the ejector effect of the jet of water from the nozzle in slot shape 33 at the inlet of the nozzle 18 being particularly powerful.
- the injector 30 and the nozzle 18 also constitute a device for creating a static torque, in association with a curved plate 35 situated at the outlet 180 of the nozzle 18 and which constitutes a jet deflector (FIGS. 1 and 2). . Thanks to the presence of such a jet deflector 35, creating a static torque, the head 1 of the robot can easily rotate around the axis of rotation 4 when the support 2 with wheels 22 encounters an obstacle, so that the robot can easily change direction without getting stuck on the spot.
- the head 1 itself carries in the rear a vertically disposed rudder 6.
- This fin 6 may comprise for example a first triangular portion 61 secured to the head 1 and which may be essentially placed along the longitudinal axis of the head 1 and a rear portion 62 articulated on the triangular portion 61 and forming an adjustable angle with the triangular portion 61.
- the rear portion 62 can thus act as a rudder while the front portion of the fin 6 constitutes a fixed axial plane.
- drift 6 which may have other configurations or also be split, with two fins placed on either side of the axis of the nozzle 18, allows to generate a dynamic torque that opposes the couple static rotation produced by the This results in a balance that allows the robot to move substantially in a straight line on the bottom of the pool between two obstacles.
- Patent document FR 2 836 945 describes other embodiments of a device for creating a static torque and a device for creating a dynamic torque which make it possible to obtain for a cleaning robot these same stabilizing effects of the damping trajectory of rotational movements and automatic change of direction in case of stop of the robot support against an obstacle.
- the cleaning robot to ensure that the cleaning robot will eventually cover the entire bottom of a basin delimited by side walls, without favoring certain areas, such as peripheral areas, it is implemented an additional mechanism that allows intermittent rerouting of the robot randomly. This diversion is caused according to predetermined angular positions of the head 1 relative to the support 2.
- the additional mechanism acts on the static torque created within the robot to modify it in the direction of an increase, when predetermined relative angular positions of the head 1 and the support 2 are reached. Since the robot is required to change its orientation many times each time it comes into abutment against a wall of the basin, the diversions are frequent and therefore the robot can thus travel the whole of a pool to clean without confining oneself to privileged areas.
- the additional mechanism comprises a cam or roller 42 mounted on the support 2 near the outer ring 41 of the central bearing, and a cam lever 37 which is connected to the diverter plate of jet 35, itself mounted pivoting about an axis 36 parallel to the axis 4 of the main bearing of the robot ( Figures 1 and 2).
- FIG. 4 shows a particular example of a cam lever 37 mounted on the lower plate 12 of the head 1, being articulated as the jet deflector 35 about an axis 36 and having a profiled position 370 in the form of a cam located parallel to a horizontal upper plate of the support 2 in the vicinity of the circular outer ring 41 of the central bearing of the robot.
- a cam 42 for example circular, is mounted on the upper horizontal plate of the support 2, in the vicinity of the outer ring 41 and can rotate freely about an axis.
- the cam 42 comes into contact with the profiled surface 370 of the cam lever 37, the latter undergoes an angular displacement about the axis 36, for example of the order of 5 to 30 °, which causes at the same time a rotation the jet deflector 35 and consequently a change in the static torque and a change of direction of movement of the robot.
- a stop 38 fixed on the lever 37 and cooperating with the flange of the lower plate 212 of the head 201 limits the angular movement of the lever 37.
- FIG. 4 shows an example of a cam lever 37 with perforated portions 371, 372, 373.
- This cam lever 37 is shown in dashed lines in a position 37A produced when the cam 42 is in position 42A, also shown in dashed lines.
- the openings 371, 372, 373 are then in position 371A, 372A, 373A.
- the cam 42 arrives at the position 42B, it no longer exerts an action on the cam lever 37 which can return to its original position.
- the cleaning robot of Figures 5 to 8 is very similar to the robot of Figures 1 to 4 and also has a modular design with a head 201 rotatable about an axis 204 perpendicular to the ground, with respect to a support 202 resting on the 222.
- a waste storage compartment 207 is attached to a plate 215 secured to the head 201 and located under an upper plate of the support 202, as in the embodiment previously described.
- the various elements of the robot of FIGS. 5 to 8 having the same function as those of the robot of FIGS. 1 to 4 carry the same reference numbers in terms of units or tens, but also have a number of hundreds equal to 2.
- the head 201 and the top plate 210 of the head 201 of the robot of FIGS. 5 to 8 correspond to the head 1 and the upper plate 10 of the head 1 of the robot of FIGS. 1 to 4.
- the support 202 and the receptacle 207 may be exactly identical respectively to the support 2 and to the receptacle 7 of the robot of FIGS. 1 to 4 and these interchangeable elements will therefore not be described again. .
- the head 201 of FIGS. 5 to 7 presents variant embodiments with respect to the head 1 of FIGS. 1 to 3.
- the device 230 for injecting liquid under pressure which, moreover, may be identical to the device 30 described above, is offset, as the nozzle 203 for connection to a pressurized water supply pipe, relative to the axis 204 and the nozzle 218 is itself eccentric with respect to the axis 204.
- the side wall 211 of the head 201 may have a whistle shape with a portion 218 constituting the eccentric nozzle ( Figure 7).
- the head 201 may have an upper plate 210 symmetrical with respect to a plane containing the axis 204 and a lower plate 212 having a cutaway side without the nozzle 218.
- a steerable drift 206 is mounted on the head 201 by being articulated about an axis 236 parallel to the axis 204 of the main ball bearing 240.
- This drift 206 may be flat or may also include a curved rear portion or hinged as the portion 62 of the embodiment of Figure 1.
- nozzle 218 is made eccentrically with respect to the axis 204 of rotation of the head 201 relative to the support 202 defines a device for creating a static torque during the ejection of a jet d pressurized water through this nozzle 218, without even having to implement a jet deflector. This static torque then remains constant.
- drift 206 is articulated around an axis 236 makes it possible to modify the dynamic torque.
- an additional mechanism 237, 242 which may be similar to that previously described with reference to FIG. 4, is thus used with a cam 242 mounted on a horizontal plate of the support 202. in a zone located in the vicinity of the outer ring 241 of the bearing, and a cam lever 237 mounted on the lower plate 212 of the head 201 being articulated about an axis 236.
- the cam lever 237 cooperating with the cam 242 is however connected by a connecting rod 234 to the steerable drift 206 and can control the rotation thereof about the axis 236 (itself secured to the head 201), whereas in the case of the robot of FIGS.
- the cam lever 37 controls the rotation of the jet deflector 35 about an axis 36.
- the axis 236 can itself serve as connecting rod between the cam lever 237 and the derriere ve 206, so that the rod 234 can then be removed.
- the axis 236 is mounted on the head 201 by means of integral bearing rings of this head 201.
- the robot of the second embodiment thus acts by an additional mechanism 237, 241, 234 to change intermittently the dynamic torque as a function of predetermined angular positions of the support 202 relative to the head 201, while the static torque defined by the eccentricity of the nozzle 218 remains constant. However, there is intermittently randomly, as in the first embodiment in which it acts on the static torque, a break in the balance between static torque and dynamic torque.
- a stop 238 similar to the stop 38 of FIG. 4 can be used on the cam lever 237.
- a return spring 239 can be used. between a point 243, remote from the axis 236, the cam lever 237 and a point 244 of the head 201 located outside the passage of the cam 242 mounted on the support 202.
- the return spring 239 allows, after an interaction between the cam 242 and the profiled portion 270 of the cam lever 237, to return the lever 237 and the axis of the drift 206 in an equilibrium position of the drift 206 with a steering angle corresponding to a cruise regime with equilibrium of the static torque.
- a double-acting cam lever 237 having a symmetrical shape with respect to a vertical plane passing through the axis 236 and thus being able to act, irrespective of the direction of rotation of the head 201 relative to the support 202.
- the support 302 with arms 321 at the ends of which are fixed rollers 322 can be very similar to the supports 2 and 202 described above.
- the support 302 is, however, arranged at the bottom of the robot with a head 301 whose upper part 310 is constituted by a removable cover and which itself constitutes a waste storage compartment.
- the lid 310 of the head 301 has a nozzle 303 for connection to a pressurized water inlet pipe.
- the nozzle 303 is eccentric with respect to the axis 304 of rotation of the head 301 with respect to the support 302.
- the lid 310 carries at its rear part two stabilizing fins 306A, 306B which can be fixed.
- the head 301 is, when the lid 310 is removed, as a whistle-shaped casing (Figure 11) with a bottom 312 provided with a central opening surrounded by a cylindrical chimney 314A, a side wall 311 and an eccentric nozzle 308 whose convergent input
- a filter 307 separates a first compartment into which the stack 314A opens a second compartment comprising the injection device 330 and the nozzle 308.
- the water drawn through the opening 313 passes through the filter 307 in the second compartment to to be ejected by the nozzle 308 while the dirt remains in the first compartment of the head 301.
- the static torque is created by the jet of pressurized water supplied by the injection device 330 and ejected through the nozzle 308.
- additional device 335 jet deflection may optionally be mounted at the outlet of the nozzle 308.
- a dynamic torque is created during the movements of the robot by the stabilization drifts 306A, 306B and a vertical master plane 305 placed at the front of the head 301 of the robot and articulated thereon about a vertical axis 336 parallel to the axis 304 of rotation of the head 301.
- an additional mechanical device is provided for intermittently modifying the equilibrium between the static torque and the dynamic torque as a function of predetermined angular positions of the support 302 with respect to the head 301.
- the additional mechanism comprises a cam 341 surrounding the outer ring of the central bearing which is integral with the support 302, and a lever 337 parallel to the cam 341 and articulated around the axis 336 of rotation of the vertical master plane 305.
- a lever end 337 is made integral with the vertical front plane 305 while the other end of the lever 337 is provided with a wheel 342 which cooperates with the cam 341 for some relative angular positions of the support 302 and the head 301.
- the lever 337 is not actuated by the cam 341, the elongated portion of which is not opposite the wheel 342.
- the wheel 342 is shown in contact with the cam 341. and under the action of this cam 341, the lever 337 can temporarily modify the orientation of the master plane before 305 and thereby change the balance between static torque and dynamic torque so as to cause a trap of the robot.
- levers 37 or 237 of the first two embodiments could cooperate with a cam similar to the cam 341 and centered on the axis of rotation of the robot head relative to the support, rather than with a roller 42 or 242.
