Description

[0001] DESCRIPTION

[0002] LAUNDRY WASHING AND DRYING DEVICE

[0003] TECHNICAL FIELD OF THE INVENTION

[0004] The present invention relates to a device and a method for washing and drying laundry. In particular, the present invention relates to the field of self-service laundromats, especially public laundromats.

[0005] STATE OF THE ART

[0006] Currently, to do laundry, a user can use an individual appliance or a shared laundromat. If using an individual appliance, the user may have a washing machine, a dryer, or a combination washing machine and dryer. However, individual machines are energy-intensive because they do not optimize thermal efficiency.

[0007] In traditional shared laundromats, several high-capacity washing or drying machines are placed side by side. Managing the usage time of these machines, as well as the loading and unloading times, is inefficient. Furthermore, the hot air generated by the machines is often released into the ambient air, thus preventing any heat recovery.

[0008] Automated laundry systems exist, such as those described in French patent application FR 2 824 339 A1. However, these systems are very bulky, requiring a significant operating space. Each drying or washing module is associated with an arm that retrieves a drum from a storage area. The drum is then positioned around a drive shaft, which necessitates additional space for this shaft as well as a robust coupling mechanism between the drum base and the shaft to withstand the stresses exerted during the washing or drying process.

[0009] Similarly, patent application FR 2 914 654 A1 describes a drum storage system and its successive movement to a module that simultaneously washes and dries laundry. The drum is also positioned around a drive shaft, which necessitates additional space for this shaft and a robust coupling mechanism between the drum base and the shaft to withstand the stresses exerted during washing or drying.

[0010] These systems are therefore not compact, are energy-intensive, and require highly complex means to position and then operate the drums. In particular, a drive system using a shaft passing through the center of the drum's base means that other means must be implemented to secure the shaft to the drum. Indeed, the forces exerted by wet laundry, which can average up to 25 kg, and which can generate a significant centrifugal force once the laundry is distributed around the drum's perimeter during the spin cycle, are too great for the small diameter of a drive shaft.

[0011] SUMMARY OF THE INVENTION

[0012] The present invention aims to remedy all or part of these drawbacks.

[0013] It offers a modular automatic laundry system in which the drum axis is maintained in a nearly horizontal plane. The drum is moved from module to module and driven in rotation by a gear system located on its periphery, which improves the compactness of the device.

[0014] BENEFITS PROVIDED

[0015] According to a first aspect, the present invention relates to a laundry washing and drying device, which comprises:

[0016] - at least two movable drums equipped with an external radial engagement means positioned at the periphery of the drum,

[0017] - at least one washing module, comprising:

[0018] - a means for rotating said drum configured to couple with the means for engaging said drum;

[0019] - a means of washing the contents of the drum,

[0020] - at least one drying module, comprising:

[0021] - a means for rotating said drum configured to couple with the means for engaging said drum; and

[0022] - a means of drying the contents of the drum;

[0023] - at least one means for moving a drum comprising a means for attaching to the drum and configured to move the drum from one module to another and

[0024] - a control system configured to control the means of movement of at least one drum, at least one washing module and / or at least one drying module.

[0025] Thanks to these arrangements, the drum axis is maintained in a substantially horizontal position at all times, regardless of its orientation. Furthermore, the drum is equipped with an external radial engagement means positioned around its periphery, and each module couples with this engagement means to drive the drum's rotation, increasing the device's compactness. The drive means can therefore be positioned radially relative to the drum. Consequently, the space required to position this drive means is reduced.

[0026] In some embodiments, the device includes a support structure for each module, the support structure having at least two superimposed and / or juxtaposed locations, each location being configured to support one module.

[0027] Thanks to these arrangements, the device's structure takes the form of a matrix in which the module locations are positioned, with the drum moving from one point in the matrix to another. The recoil required to move the module is therefore very small and roughly equal to the drum's dimension along its axis.

[0028] In some embodiments, the means of transport includes:

[0029] - at least one first guide rail for the translation of the attachment means along a first direction,

[0030] - at least one second guide rail for the translation of the attachment means along a second direction perpendicular to the first direction, moving along said first guide rail, and

[0031] - at least one third translational guide rail of the attachment means along a third direction perpendicular to the first and second directions, moving along said second guide rail.

[0032] Thanks to these arrangements, the means of transport is attached to the structure and is very compact. Since the drum's axis is only offset, there is no need to provide space for the drum's rotation. The device's compactness is therefore further improved.

[0033] In some embodiments, each drum comprises, at least in part, a coating of ferromagnetic material, the hooking means comprising an electromagnet controlled by the control system.

[0034] Thanks to these features, the drum can be attached to the transport device by its circumference, thus limiting the stress on the attachment. With the stress reduced, it is therefore possible to decrease the amount of material required. Furthermore, the system is more energy-efficient because the weight of the components to be transported is reduced.

[0035] In some embodiments, the washing module includes a washing tank configured to receive a drum, the washing tank having at least one door operated by the control unit.

[0036] Thanks to these features, only the drum is moved, which limits the energy required for the device to operate. The tub closes around the drum to create a watertight seal.

[0037] In some embodiments, an opening covered by a door is positioned zenithally.

[0038] Thanks to these arrangements, it is possible to load the washing module tub from the top without having to change the orientation of the drum.

[0039] In some embodiments, the washing module includes a clean water and detergent inlet and a dirty water outlet, positioned on either side of the tub along an axis corresponding to the axis of rotation of a drum when the drum is positioned in the tub.

[0040] Thanks to these arrangements, the water flow is directed along the line, thus simulating a river current. Combined with the drum's rotation, these embodiments allow for greater contact between the laundry and the water while respecting the fabric fibers. Washing time and energy consumption are therefore reduced. In some embodiments, the engagement means comprises at least one set of teeth formed radially on the drum's periphery, the set of teeth forming a toothed wheel that defines an axis of rotation for the drum.

[0041] Thanks to these provisions, the complexity of manufacturing drums is reduced and the compactness of the drums is improved.

[0042] In embodiments, each at least one drying and / or washing module includes at least two guide wheels configured to form support points for a drum on its periphery.

[0043] In some embodiments, the drive means includes a pinion configured to form a gear with the toothed wheel of said drum, and a motor controlled by the control system to actuate the pinion.

[0044] Thanks to these arrangements, the drum is held in position and vibrations are limited by the guide wheels, while the drive is provided by a pinion driven by a motor and positioned tangentially to the drum.

[0045] In some embodiments, at least one washing and / or drying module includes a motor controlled by the control unit, the motor having an axis of rotation parallel to and different from an axis of rotation of the drum.

[0046] Thanks to these arrangements, it is possible to place the motor next to the drum to drive it in rotation by means of a toothed wheel, for example.

[0047] In some embodiments, each module and each drum defines a volume, the motor being placed in the volume of the module, the axis of rotation of the motor passing through the volume of the module and being external to the volume of the drum when the drum is placed in the module.

[0048] Thanks to these arrangements, the motor is contained within the module's volume without interfering with the drum module. In other words, the motor can be placed next to the drum, within the module's defined space. This increases the compactness of each module.

[0049] In alternative embodiments, each module and each drum defines a volume, with the motor placed in the volume of the module, the axis of rotation of the motor passing through the volume of the module and the volume of the drum when the drum is placed in the module.

[0050] Thanks to these arrangements, the motor can mesh with a toothed wheel fixed to one of the drum's bases, which has a diameter smaller than the drum's diameter. This increases the device's compactness.

[0051] In some embodiments, each drum includes a means of access to the contents of a drum by a user comprising a diaphragm actuated by a toothed wheel positioned on the periphery of the drum.

[0052] Thanks to these features, the device eliminates the need for a hinged door, further reducing its overall size. Moreover, since the control unit can operate the diaphragm, access is restricted to authorized users. These embodiments also prevent the loss of any of the drum's contents during transport.

[0053] In some embodiments, each drum includes a drum identification means and each module includes a means for reading the identification means configured to detect the presence of a drum in said module and identify said drum.

[0054] Thanks to these arrangements, the contents of each drum can be washed and dried according to the user's wishes to respect the laundry contained in that drum.

[0055] In some embodiments, the device also includes a means for analyzing the contents of a drum, and the control system includes a means for communicating with a machine learning means configured to adapt the operating mode of a drying and / or washing module according to the result of the analysis performed.

[0056] Thanks to these features, the contents of each drum, including the materials composing the laundry, can be detected automatically and the washing and / or drying cycle can be adapted according to the detected elements.

[0057] In some embodiments, the analysis means includes at least one sensor from among:

[0058] - a mass measurement sensor,

[0059] - a means of spectrometric analysis and / or

[0060] - a means of capturing at least one image.

[0061] Thanks to these features, the contents of each drum, including the materials composing the laundry and the type of stain, can be automatically detected, and the washing and / or drying cycle can be adapted according to the detected elements.

[0062] In embodiments, wherein the analysis means includes a means for detecting a living being in the drum.

[0063] These embodiments make it possible to avoid bodily injury by stopping the operation of the device.

[0064] According to a second aspect, the present invention relates to a system comprising at least two devices of the present invention, which includes a machine learning means, a means of communication with each device of the system and a means of sending instructions to at least one control automaton according to the learning carried out.

[0065] Since the goals, advantages and special characteristics of the system that is the subject of the present invention are similar to those of the device that is the subject of the present invention, they are not recalled here.

[0081] DESCRIPTION OF IMPLEMENTATION METHODS

[0082] The present description is given by way of non-limiting attribution, each feature of an embodiment being able to be advantageously combined with any other feature of any other embodiment.

[0083] The expression "and / or," as used in this document, should be understood as meaning "either or both" of the elements thus joined, that is, elements that are present conjunctively in some cases and disjunctively in others. Multiple elements listed with "and / or" should be interpreted in the same way, that is, "one or more" of the elements thus joined. Other elements may also be present, besides those specifically identified by the "and / or" clause, whether or not they are related to those specifically identified elements.Thus, by way of non-limiting example, a reference to "A and / or B", when used in conjunction with an open language such as "including", may refer, in one embodiment, to A only (possibly including elements other than B); in another embodiment, to B only (possibly including elements other than A); in yet another embodiment, to A and B (possibly including other elements); etc.

[0084] Figures 1 to 8 and 10 each present an orthogonal coordinate system; the X, Y and Z axes correspond to the same directions in space; only the angle of view of figures 1 to 8 and 10 changes, thus modifying the representation of these directions in space.

[0085] We call:

[0086] - “access side”, which is shown in the background of figures 1, 4 to 8 and 10 and in the foreground of figure 3,

[0087] - “Technical side” which is represented in the foreground of figures 1, 4 to 8 and 10 and in the background in figure 3,

[0088] - “left” refers to what is represented on the left side of figures 1, 4 to 8 and 10, 13 and 14, in the background of figure 2 and on the right side of figure 3,

[0089] - "right" which is represented on the right of figures 1, 4 to 8 and 10, 13 and 14, in the foreground of figure 2 and on the left of figure 3.

[0090] The access side corresponds to the surface visible to the user, while the technical side corresponds to the laundry processing equipment, hidden from the user, in which at least one drum moves.

[0091] Three orthogonal axes, X, Y, and Z, are defined here. The Z axis is vertical when the device of the present invention is under normal operating conditions. The X and Y axes are horizontal when the device of the present invention is under normal operating conditions. The Y axis extends from the access side to the technical side. The X axis extends along the access side.

[0092] Figure 1 shows a washing and drying device for laundry 100, which is the subject of the present invention.

[0093] Drum

[0094] The device 100 comprises at least two movable drums 109, shown in figures 2 and 3.

[0095] A rotating drum 109 has a cylindrical shape 201 with a hollow circular base 202 and 203. The rotating drum 109 has a rotation axis YT. The cylinder 201 is preferably made of a material, such as sheet metal, perforated to allow water to pass through during washing and moisture during drying. Preferably, the drum 109 has, at least in part, a coating of a ferromagnetic material. For example, the cylinder 201 is made of a ferromagnetic material, such as stainless steel.

[0096] The drum 109 has a base 202, called the "bottom," which is blind and made of a solid or perforated material such as sheet metal. In some embodiments, the base 202 is a flat surface. In other embodiments, the base 202 may have at least one pattern indicating the mixing of the laundry, a characteristic known to those skilled in the art, on the surface facing the inside of the cylinder 201.

[0097] The drum 109 is equipped with an external radial engagement means positioned on the periphery of the drum 205. It is recalled that "peripheral" means: located on the periphery of a circular or oval object and that "radial" means "which is arranged, directed or which is exerted, is carried out along a radius, that is to say perpendicular to an axis".

[0098] Thus, an external engagement means that the engagement means is not contained within the volume of the truncated cylinder defining the drum. The fact that this engagement means is located on the periphery of a drum element means that it is positioned on the portion of the truncated cylinder between the two bases or attached to one of the bases. The fact that the engagement means is radial means that the engagement follows the radii of the circle defining the truncated cylinder.

[0099] For example, such an engagement means 205 comprises at least one set of teeth formed radially on the periphery 201 of the drum 109, the set of teeth forming a gear 205 defining an axis of rotation YT of the drum 109.

[0100] Preferably, gear 205 is positioned at a distance from base 202 less than or equal to half the distance between bases 202 and 203 along the YT axis. Even more preferably, gear 205 is positioned at a distance from base 202 less than or equal to one-quarter of the distance between bases 202 and 203 along the YT axis. Even more preferably, gear 205 is positioned adjacent to base 202.

[0101] In some embodiments (not shown), a gear is a gear with a diameter smaller than the diameter of the base 202 attached to the base 202. Preferably, the diameter of said gear is greater than or equal to half the diameter of the base 202.

[0102] The gear 205 preferentially has straight teeth to transmit the same torque, regardless of the direction of rotation imposed on the drum 109.

[0103] In preferred embodiments, the drum 109 has, on the cylinder 201, at least one tread, 206 and / or 204, configured to be in contact with a guide wheel, 406 or 510. The tread is made of a material having a coefficient of friction greater than 0.2. Such a material is preferably polyurethane.

[0104] Preferably, the drum 109 has a tread 204 near the bottom 202 and a tread 206 near the base 203.

[0105] The drum 109 has a base 203 called the "access face," which is hollow and includes a means of access to the contents of the drum 109 by a user. The access means may be at least one door (not shown), for example, mounted on a hinge with an axis of rotation in a plane normal to the axis YT.

[0106] In some embodiments, the means of accessing the contents of a drum by a user includes a diaphragm actuated by a toothed wheel positioned on the periphery of the drum 109, for example made in a similar manner to the diaphragm of a camera, but of different dimensions.

[0107] Such a diaphragm is shown in Figure 3 and comprises at least two blades 209 mounted for rotation about a toothed wheel. The toothed wheel is mounted around the base 203, which rotates with the drum cylinder 201 about the axis YT. In other words, the blades 209 are mounted for rotation about axes parallel to the axis YT, said axes following a circular arc whose center is the axis YT.

[0108] The lugs 208 are mounted on an actuating plate 210 perpendicular to the axis YT. The actuating plate 210 is mounted on the access face 203, by interlocking with the cylinder 201 of the drum 109. The actuating plate 210 has a circular ring shape defining an "outer" circle, furthest radially from the axis YT, and an "inner" circle, closest radially to the axis YT. Preferably, the diameter of the inner circle is greater than or equal to half the diameter of the outer circle.

[0109] Each blade 209 has a groove 211 for guiding a lug 208. The shape of each blade 209 is constrained such that: when the diaphragm is closed, the access face 203 is covered by the blades, the blades do not protrude radially from the actuating plate 210 and when the diaphragm is open, the inner circle is completely uncovered.

[0110] Actuating the gear causes the blades 209 to rotate, and the engagement of the lugs 208 in their respective grooves 211 results in the radial movement of the blades. As shown in Figure 3, counterclockwise rotation of the gear around the YT axis causes the diaphragm to close. Conversely, clockwise rotation of the gear around the YT axis causes the diaphragm to open.

[0111] In preferred embodiments shown in Figures 2 and 3, the toothed wheel is replaced by a plate with holes, the axes of which are parallel to the axis of rotation of the drum YT and regularly spaced. The plate with holes and the actuating plate 210 are then fixed relative to each other and can be rotated about the axis of rotation YT of the drum 109 at the access face of the drum 109. The lugs 208, the grooves 211, and the blades 209 are similar to those described above.

[0112] In these embodiments, the opening of the diaphragm is operated by blocking the plate with orifices 207, for example by inserting a retractable pin into one of the orifices of said plate, and then by rotating the drum by means of the toothed wheel 205.

[0113] In the embodiment shown in Figure 1, only one drum 109 is visible. Preferably, the device 100 of the present invention has at least as many drums 109 as the sum of the number of drying modules and the number of washing modules. Preferably, the device 100 of the present invention has at least as many drums 109 as the sum of the number of drying modules, the number of washing modules, and the number of storage modules minus one.

[0114] The device 100 is such that, regardless of the position of each drum 109 in the device 100, the rotation axis YT of the drum is parallel to an axis going from the access side to the technical side of the device represented by the Y axis in Figure 1. In other words, the access face is oriented towards the access side and the bottom is oriented towards the technical side, regardless of the position of the drum 109 in the device 100.

[0115] Preferably, each drum 109 of the device 100 has a unique identification means. Such a unique identification means is, for example, an RFID chip with a unique identifier. Preferably, to avoid supplying electrical power to the drum 109, the RFID chip is passive.

[0116] Drying module

[0117] Device 100 includes at least one drying module 111 shown in Figure 6. In the embodiment shown in Figure 1, device 100 includes five drying modules.

[0118] Each drying module 111 includes:

[0119] - a drive means 408 for rotating said drum 109 configured to couple with the engagement means 204 of said drum 109; and

[0120] - a means of drying 404 of the contents of the drum;

[0121] Preferably, the drying module 111 includes a sealed enclosure 401. The sealed enclosure 401 may have a rectangular parallelepiped shape with dimensions corresponding to the dimensions of the drum 109.

[0122] Within the sealed enclosure 401, that is, between the walls defined by the sealed enclosure 401, there is at least one drying means 404. The drying means 404 includes at least one infrared emitting lamp. Preferably, each infrared emitting lamp is positioned on an edge of the sealed enclosure 401 to minimize the overall size of the drying module.

[0123] In some embodiments, the drying means includes a means for circulating hot air.

[0124] The drive means 408 includes a pinion configured to form a gear with the toothed wheel 204 of said drum 109, and a motor (not shown) controlled by a control system to actuate the pinion 408. In other embodiments, the drive means 408 is a worm screw or any other means of power transmission known to those skilled in the art.

[0125] Preferably, the motor has a rotation axis parallel to and different from a rotation axis YT of the drum. Even more preferably, the motor is located within the volume of module 111, and the motor's rotation axis passes through the module's volume and is external to the volume of drum 109 when drum 109 is placed within the module. This facilitates drum positioning and prevents collisions between the drum and gear 408 or the motor.

[0126] Even more preferably, the motor is placed in the axis of rotation of the pinion 408 and in a plane normal to the axis of rotation of the pinion 408, the volume of the motor is less than the diameter of the pinion 408.

[0127] In alternative embodiments where the gear is attached to the base 202 of the drum, the motor is located within the module volume, with the motor's axis of rotation passing through both the module volume and the volume of the drum 109 when the drum 109 is placed within the module. In alternative embodiments where the gear is attached to the base 202 of the drum, the motor can also be located within the module volume 111, and the motor's axis of rotation passes through the module volume and is external to the volume of the drum 109 when the drum 109 is placed within the module; in this case, the diameter of the pinion 408 is chosen to mesh with the gear.

[0128] In embodiments, at least two guide wheels 406 are configured to form support points for a drum 109 on its periphery 201. The guide wheels 406 are positioned on supports 405 so that at least two guide wheels 406 are in contact with the cylinder 201 of the drum.

[0129] Preferably, each support 405 has three wheels 406 positioned on an arc of a circle such that an arc of a circle tangent to each wheel 406 of a support corresponds to the outside diameter of the cylinder 201 of a drum 109.

[0130] Preferably, the sealed enclosure 401 comprises two supports 405 such that an arc of a circle tangent to each wheel 406 of said two supports 405 corresponds to the outside diameter of the cylinder 201 of a drum 109.

[0131] Each support 405 is positioned in the sealed enclosure 401 such that a drum 109 can be circumscribed by the sealed enclosure 401 and at least one support 405 is positioned opposite a tread, 206 and / or 204 of a drum 109 when a drum 109 is inserted into the sealed enclosure 401.

[0132] Even more preferably, two pairs of supports 405 are positioned in the sealed enclosure 401 opposite each tread, 206 and 204, of a drum 109 when a drum 109 is inserted into the sealed enclosure 401.

[0133] The sealed enclosure 401 preferably includes a motorized door operated by the control unit. The door is configured to be opened to insert or remove a drum 109 from the sealed enclosure.

[0134] Preferably, the door is mounted so that its movement is maintained in a plane perpendicular to the Y-axis. For example, the door is mounted to move along an axis, such as the vertical Z-axis. The sliding connection is achieved by any means known to those skilled in the art. For example, a rack or a belt is fixed to the door, and a toothed wheel is driven to cause the door to move along the axis defined by the rack or belt.

[0135] In some embodiments, each drying module 111 includes a ventilation means comprising an air inlet 402 and an air outlet 403. In order to share the energy consumption associated with the ventilation of the drying modules 111, the air inlet 402 of a drying module 111 is preferably connected directly to the air outlet 403 of an adjacent drying module.

[0136] In some embodiments, each sealed enclosure 401 is equipped with a moisture filtration means, preferably self-cleaning.

[0137] Washing module

[0138] The device 100 includes at least one washing module 114 shown in figures 7 and 8. In the embodiment shown in figure 1, the device 100 includes two washing modules 114.

[0139] Each 114 washing module includes:

[0140] - a means for rotating a drum 109 configured to couple with the engagement means 204 of said drum;

[0141] - a means of washing, 505, 506, 507, of a drum contents.

[0142] The means of rotating the washing module is similar to the means of rotating the drying module described above.

[0143] The washing module includes a structure 501 configured to support a washing tank 505. The structure 501 is, for example, made of welded metal profiles, for example, with a square or rectangular cross-section. The washing tank, 502, 503, and 505, has the shape of a hollow, truncated right cylinder with a polygonal or circular base. The washing tank 502, 503, and 505 is watertight and includes at least one water inlet 506, one detergent inlet, and one dirty water outlet 507. In some embodiments, the water inlet and detergent inlet are combined, the water and detergent being mixed upstream of the introduction of the water into the washing tank.

[0144] In the embodiments shown, the washing tank, 502, 503, and 505, has a plane of symmetry passing through the center of gravity of the washing tank, 502, 503, and 505, and parallel to a plane containing the Y and Z axes. A plane called the "opening plane" delimiting a fixed and a movable part of the tank is defined. The opening plane is parallel to a plane containing the X and Y axes and passing through the center of gravity of the washing tank, 502, 503, and 505.

[0145] Preferably, the fixed portion 505 of the tank consists of half of the truncated cylinder between the opening plane and the ground, and the entirety of each base of the cylinder. The fixed portion 505 of the tank is attached to the structure 501 in the opening plane. The water inlet 506 preferably comprises a plurality of orifices uniformly distributed along one side of a plane of symmetry. Preferably, the plurality of orifices is aligned on a straight line parallel to the Y-axis. The plurality of orifices is positioned on the fixed portion of the tank.

[0146] In embodiments (not shown) in which the detergent inlet is separate from the water inlet, the detergent inlet preferably comprises a plurality of orifices uniformly distributed on the side of the plane of symmetry containing the water inlet. Preferably, the plurality of orifices is aligned on a line parallel to the Y-axis. The plurality of orifices is positioned on the fixed part 505 of the washing tank.

[0147] Water inlet 506 is connected to a water supply pipe 511.

[0148] The dirty water outlet 507 preferably has a plurality of orifices uniformly distributed on the side opposite the water inlet 506 to the plane of symmetry. Preferably, the plurality of orifices is aligned on a straight line parallel to the Y-axis. The plurality of orifices is positioned on the fixed part 505 of the wash tub. This positioning simulates a water flow within the tub and results in improved laundry washing performance.

[0149] Given the position of the plane of symmetry, the washing module includes the inlet 506 for clean water and detergent, and the outlet for dirty water 507. The inlet and outlet are positioned on either side of the tub, 502, 503 and 505, along an axis corresponding to the axis of rotation of a drum when the drum is positioned in the tub.

[0150] Water inlet 506 is connected to a water drain pipe 512.

[0151] The water cycle is described below in relation to figure 9.

[0152] The washing tank, 502, 503 and 505, includes at least one door, 502 and 503, operated by the control unit. The set of doors, 502 and 503, forms the moving part of the washing tank, 502, 503 and 505. Each door is assembled to the fixed part and configured so that the washing tank, 502, 503 and 505, forms a sealed unit.

[0153] Preferably, the drive means is positioned on one of the doors 503. Such positioning avoids contact between water and the drive means and therefore simplifies the sealing to be implemented.

[0154] Preferably, the 503 doors are equipped with a locking mechanism. For example, the door locking mechanism includes at least one latch mounted in a groove and equipped with a spring to automatically engage the latch in a strike plate positioned on the other 503 door.

[0155] Preferably, the latching arm comprises an element made of ferromagnetic material, the latching arm being retracted by means of an electromagnet activated only when retraction of the latching arm is necessary, for example to open the doors 503. In some embodiments, the locking means may include a sensor for the position of the latching arm, the values ​​measured by said sensor being transmitted to the control unit 150. In the embodiments shown in Figures 7 and 8, the tank has two doors, 502 and 503, on either side of the plane of symmetry of the washing tank, 502, 503 and 505. Each door has an actuating frame 502 and a leaf 503. In the closed position, the leaves 503 and the fixed part 505 form the washing tank.

[0156] The leaves 503 are preferably formed of the same material as the fixed part 505.

[0157] Each reinforcement 502 is assembled by a pivot joint with an axis parallel to the Y axis to the reinforcement 501. Preferably, each pivot joint is positioned in the opening plane outside the fixed part 505.

[0158] For each frame, an actuator 504 is attached on one side to the structure 501 and on the other side to the frame 502. The actuator 504 is preferably a cylinder. When the control unit commands the cylinder rod to retract, the leaf 503 associated with the frame 502 opens. When the control unit commands the cylinder rod to extend, the leaf 503 associated with the frame 502 closes. Preferably, each frame 502 is associated with two cylinders 504 having parallel axes of rod movement.

[0159] In other embodiments, the actuator is a motor whose rotational actuation in one direction is configured to open the leaf 503 associated with the frame 502, the rotation in the opposite direction being configured to close said leaf 503.

[0160] The embodiments shown in figures 7 and 8 make it possible to limit the size of the washing module 114 when the doors, 502 and 503, are open.

[0161] Preferably, each flap 503 covers, at least partially, an opening positioned zenithally. In the embodiments shown in Figures 7 and 8, the opening represents half of the radial wall of the cylinder trunk of the washing tank positioned on the side of the opening plane furthest from the ground.

[0162] In embodiments, at least two guide wheels 510 are configured to form support points of a drum 109 on its periphery 201. The guide wheels 510 are positioned on supports, 508 and 509, so that at least two guide wheels 510 are in contact with the cylinder 201 of the drum.

[0163] Preferably, each support, 508 and 509, has three wheels 510 positioned on an arc of a circle such that an arc of a circle tangent to each wheel 510 of a support corresponds to the outside diameter of the cylinder 201 of a drum 109.

[0164] Preferably, the fixed part 505 of the washing tank comprises two supports 508 such that an arc of a circle tangent to each wheel 510 of said two supports 508 corresponds to the outside diameter of the cylinder 201 of a drum 109.

[0165] Preferably, each flap 503 of the washing tank has at least one support 509 such that an arc of a circle tangent to each wheel 510 of said support 509 corresponds to the outside diameter of the cylinder 201 of a drum 109. On the doors, the supports 509 are positioned opposite a frame 502 with respect to the flap 503. This allows the forces to be transmitted directly from the supports 509 to the frames 502 along a radial axis.

[0166] In the embodiments shown in figures 7 and 8, each leaf 503 has a support 509 and the fixed part 505 has two supports 508.

[0167] Each support, 508 and 509, is positioned in the tub such that a drum 109 can be circumscribed by the tub and at least one support, 508 or 509 is positioned opposite a tread, 206 and / or 204 of a drum 109 when a drum 109 is inserted into the washing tub.

[0168] Even more preferably, two sets of four supports, 508 and 509, are positioned in the tank opposite each tread, 206 and 204, of a drum 109 when a drum 109 is inserted into the sealed enclosure 401.

[0169] The dimensions along the X and Z axes are equal to the sum of the dimension of the drum along the same axis and the dimension of a support, 508 or 509, equipped with casters 510.

[0170] The means of driving the washing module corresponds to the embodiments of the means of driving described in relation to figures 5 and 6 concerning the drying module.

[0171] Figure 8 shows an embodiment of the washing module in which a drum 109 has been inserted into the tub, 502, 503 and 505, and the doors, 502 and 503, are closed.

[0172] In figure 8, the doors, 502 and 503, are open and the tank is inserted or removed by translation along an axis parallel to the Z axis by a means of displacement 300.

[0173] Storage module

[0174] Device 100 may include at least one storage module 112 shown in Figure 1. Preferably, device 100 includes two storage modules 112: one, called a "deposit" module, configured for a user to deposit soiled laundry into a drum 109, and the other, called a "retrieval" module, configured for a user to retrieve clean laundry from a drum 109. The deposit and retrieval modules are identical; only their function differs for the purpose of optimizing user workflow. Each deposit or retrieval module has an opening on the access side. Device 100 must include one of the following modules: a deposit or retrieval module, and it may also include storage modules 112 for clean, dry laundry, without an opening on the access side.

[0175] Each deposit or withdrawal module includes:

[0176] - a means for receiving a drum 109; and

[0177] - a means of actuating the access means, 208 to 211, to the contents of the drum 109.

[0178] In preferred embodiments, each deposit or retrieval module further comprises a means for rotating a drum 109 configured to engage with the engagement means 204 of said drum 109. For example, the actuating means for the access means may be a retractable pin that translates along an axis parallel to the rotation axis YT of the drum 109 and is positioned to fit into one of the orifices in the plate 207. Preferably, the retractable pin may include a spring configured to engage the pin with an orifice. When the pin is not immediately opposite an orifice, the drum is rotated, and the spring pushes the pin into the orifice once they are aligned.

[0179] Preferably, the stop comprises an element made of ferromagnetic material, the stop being retracted by means of an electromagnet activated only when retraction is necessary, for example, to keep the diaphragm closed. In some embodiments, the actuation means may include a sensor for the position of the stop, the values ​​measured by said sensor being transmitted to the control unit 150.

[0180] Each storage module 112 for clean and dry linen, without an opening on the access side, includes only a means for receiving a drum 109. In embodiments, each storage module 112 for clean and dry linen, without an opening on the access side, also includes a means for driving a rotation of said drum 109 configured to couple with the engagement means 204 of said drum 109.

[0181] Adding a drum drive means for rotating the drum 109 allows the drum 109 to rotate intermittently or continuously to prevent wrinkling of the laundry and the accumulation of moisture. The drive means corresponds to the embodiments of the drive means described opposite Figures 5 and 6 concerning the drying module.

[0182] The drum receiving means has a fixed frame configured to be fixed to the structure 101. Preferably, the fixed frame has guide wheels which are positioned on supports corresponding to the embodiments described opposite Figures 5 and 6 concerning the drying module, the supports being fixed to the fixed frame rather than in the sealed enclosure 401.

[0183] In particular embodiments comprising the mechanism shown in Figure 13, at least one storage, deposit and / or retrieval module includes a means for positioning the drum as shown in Figure 14. Such a positioning means can be fixed to a rail 901 along the X axis of the structure 101 delimiting said module.

[0184] A bracket 902, or a U-shaped support structure with dimensions corresponding to the dimension of the gear 205 along the axis of rotation of the drum YT, is mounted on the rail 901 by means of a pivot joint 903.

[0185] As shown on the left of Figure 14, when the drum 109 is moved by the shuttle into the storage, deposit and / or retrieval module, the rod of the cylinder 806 is retracted into the cylinder body, and the gear 205 lowers to come into contact with the bracket 902 or the U-shaped support structure. As shown on the right of Figure 14, under the weight of the drum 109, the bracket is rotated counterclockwise in the direction of Figure 14 so that the arms of the bracket or the U-shaped support structure find a vertical and horizontal position respectively.

[0186] The 902 bracket or the U-shaped support structure therefore guides the toothed wheel 205 on the guide supports to ensure its correct positioning on these guide supports.

[0187] In some embodiments, the positioning means is equipped with a sensor, for example a contactor, configured to detect when the drum 109 is in a position substantially aligned with the Y axis. In other words, the contactor is activated when the bracket 902 or the U-shaped support structure is lowered.

[0188] In the specific cases of the deposit or retrieval module, the rail of the structure 101 along the X axis opposite to that containing the positioning means is equipped with a roller in contact with the access face 203 of the drum 109. These embodiments make it possible to ensure the correct position of the drum in these modules, in particular to cooperate with the diaphragm.

[0189] In particular embodiments, a shock absorber, for example a spring, can be placed between the pivot joint 903 and the bracket 902 or the U-shaped support structure, to absorb the shock due to the contact of the toothed wheel 205 of the drum 109 with the bracket 902 or the U-shaped support structure.

[0190] To remove the drum 109, the rod of the cylinder 806 is extended. The attachment means 108 furthest from the positioning means 900 then engages with the drum 109, lifting it. The drum 109 is then inclined and rests on the positioning means as shown on the left of Figure 14. The other attachment means 108 is then attached to the drum. The cylinder rod is then retracted so that the drum returns to a rotation axis YT parallel to the Y-axis. Of course, such a positioning means can be positioned in any other module of the device of the present invention configured to receive a drum 109.

[0191] Structure

[0192] Device 100 includes a structure 101 defining a set of rectangular parallelepipeds, each parallelepiped being configured to receive one module from among a washing module 114, a drying module 111 and / or a storage module 112.

[0193] Structure 101 is formed by metal beams and columns. Preferably, each rectangular parallelepiped forms an autonomous structural cell. An autonomous structural cell is a self-supporting cell having attachment elements to at least one other cell and comprising one module from among a washing module 114, a drying module 111, a storage module 112; a heating module 115, a water treatment module 604, a detergent tank module 620, a pumping module 125 and / or a water tank module 601.

[0194] Preferably, each structural cell corresponding to a module configured to receive a drum 109 is a rectangular parallelepiped of which:

[0195] - The dimension along the Y-axis is between the dimension of drum 109 along the YT axis multiplied by 1.05 and the dimension of drum 109 along the YT axis multiplied by 1.75, - The dimension along the X-axis is between the dimension of drum 109 along the XT axis multiplied by 1.05 and the dimension of drum 109 along the XT axis multiplied by 3.50

[0196] - the dimension along the Z axis is between the dimension of drum 109 along the ZT axis multiplied by 1.05 and the dimension of drum 109 along the ZT axis multiplied by 4.50.

[0197] The dimensions of each structural cell corresponding to a module configured to receive a drum 109 are the same in order to allow modularity of the device 100.

[0198] The dimensions of the heating module 115, water treatment module 604, detergent tank 620, pumping module 113 and / or water tank 601 correspond to the dimensions of the modules configured to receive a drum 109, along the X and Y axes. The dimension along the Z axis may differ from those defined above.

[0199] Device 100 therefore defines a matrix of modules represented schematically in Figure 10. In Figure 10, we observe four rows of modules along the Z axis, three columns of modules along the X axis and two rows of modules along the Y axis.

[0200] The row of modules along the Y axis furthest from the access side comprises a single line of modules closest to the ground, consisting, from left to right, of a detergent tank module 604, a washing module 114 and a heating module 115.

[0201] The row of modules along the Y axis closest to the access side has four rows of modules superimposed along the Z axis.

[0202] Starting from the ground and moving from left to right:

[0203] - the first line of modules includes a water treatment module 604, a washing module 114 and a water tank module 601,

[0204] - the second row of modules includes a storage module 112, for example a deposit module, an empty module 125, a storage module 112, for example a withdrawal module,

[0205] - the third row of modules includes a drying module 111, a pumping module 113 and a drying module 111 and

[0206] - the fourth line of modules comprises three 111 drying modules.

[0207] The compactness of device 100 is defined by the number of modules.

[0208] The support structure 101 of each module, 111, 112, 113, 114, 115, 601, 604, 606, therefore comprises at least two superimposed and / or juxtaposed locations, each location being configured to support a module.

[0209] Means of transportation

[0210] The device 100 includes at least one means 300 for moving a drum 109, which has a means for attaching to the drum and is configured to move the drum from one module, 111, 112, or 114, to another. Preferably, the means 300 is configured to move each drum 109 only in translation. In the embodiments shown in Figures 1 to 11, the attachment means 108 includes at least one electromagnet, for example two, controlled by the control unit. For example, the electromagnet is configured to provide a pulling force on the drum 109 greater than or equal to the sum of the weight of the drum and a maximum weight of laundry that the drum 109 can hold. Preferably, the electromagnet is active. It should be noted that an active electromagnet produces a magnetic field when it is not supplied with an electric current.It consists of a winding and a pole piece made of a soft ferromagnetic material called a magnetic core, which channels the magnetic field lines. These embodiments allow the drum to be attached regardless of its angle of rotation around the YT axis. Furthermore, the drum is attached while maximizing the compactness of the device, since the size of such an electromagnet is limited and does not require the movement of mechanical parts to form a fixed connection with the drum.

[0211] Preferably, each electromagnet is mounted in an oblong hole and can therefore rotate about said oblong hole along an axis normal to the plane of the oblong hole. Furthermore, translation about the axis of the oblong hole can also be implemented. This ensures, in particular, good contact between the electromagnet and the body of the drum 109's truncated cylinder. In some embodiments (not shown), the attachment means is a clamp configured to grip the drum 109 around the cylinder 201. In other embodiments (not shown), the attachment means comprises a part configured to fit into a corresponding relief on the drum 109.

[0212] Preferably, means of transport 300 includes:

[0213] - at least one first rail, 102 and 103, for guiding the translation of the attachment means 108 along a first direction X,

[0214] - at least one second guide rail, 104 and 105, translating the attachment means 108 along a second direction Z perpendicular to the first direction X, moving along said first guide rail, 102 and 103, and

[0215] - at least one third guide rail 107 in translation of the attachment means 108 along a third direction Y perpendicular to the first direction X and the second direction Z, moving along said second guide rail, 104 and 105.

[0216] In the embodiment shown in figures 1, 3 and 10, the structure 101 comprises two rails, 102 and 103, parallel and parallel to the X axis. The rails, 102 and 103, are fixed to the structure on structural elements between the two rows along the Y axis. The rails, 102 and 103 are straight. Preferably, a rail 102 has a rack or a belt configured to receive a toothed wheel rotated by a motor controlled by the control unit 150. The other rail 103 may have a rack or a belt or have a square or circular profile to contribute to the translational guidance of the attachment means 108. In some embodiments, at least one rail, 102 and / or 103, has a groove configured to receive a wheel, the wheel being rotated by a motor controlled by the control unit 150.

[0217] The means of movement 300 includes at least one guide relief, 301 or 303, of profile 302 or 304, corresponding to the rail, 102 or 103, configured to form a sliding connection along an axis parallel to the X axis with the rail, 102 or 103. The parts, 301 to 304, 104 and 105 form a mobile gantry in translation along the X axis relative to the structure.

[0218] Each guide rail, 301 and 303, is fixed to at least one other rail, 104 or 105, to form a gantry. In the embodiment shown in Figures 1, 3, and 10, the other rails, 104 and 105, are parallel to the Z-axis. The rails, 104 and 105, are straight. Preferably, one rail 104 has a rack or a belt 313 configured to receive a toothed wheel rotated by a motor 305 controlled by the control unit 150. The other rail 105 may have a rack or a belt, or a square or circular profile, to assist in the translational guidance of the attachment means 108.

[0219] In some embodiments, at least one rail, 104 and / or 105, has a groove configured to receive a wheel, the wheel being rotated by a motor controlled by the control unit 150.

[0220] The movement means 300 includes at least one guide relief, 306 and 307, corresponding to the rail, 104 or 105, configured to form a sliding connection along an axis parallel to the Z axis with the rail, 104 or 105. The movement means includes a connecting profile 106 between the guide reliefs 306 and 307. The parts, 306, 307 and 107 form a carriage that moves in translation along the Z axis relative to the gantry.

[0221] In the embodiment shown in Figures 1, 3, and 10, the third rails, 310 and 311, are parallel to the Y-axis. Rails 310 and 311 are straight. Preferably, one rail 310 has a rack or a belt configured to receive a toothed wheel rotated by a motor 309 controlled by the control unit 150. The other rail 310 may have a rack or a belt, or a square or circular profile, to assist in the translational guidance of the attachment means 108.

[0222] In some embodiments, at least one rail, 310 and / or 311, has a groove configured to receive a wheel, the wheel being rotated by a motor controlled by the control unit 150.

[0223] The third rails, 310 and 311, are fixed to junction 106 of the mobile carriage.

[0224] In preferred embodiments shown in Figure 13, the rails 310 or 311 are attached to the rail 106 by a pivot joint. The rail 106 also forms a pivot joint with the guide ribs, 306 or 307. To form a swiveling bracket, a jack 806 is fixed between the end of the rails, 310 or 311, independent of the rail 106, and the end of the guide ribs, 306 or 307, independent of the rail. As shown in Figure 13, the jack 806 is a hydraulic jack.

[0225] Preferably, the body of the cylinder 806 can be fixed by a pivot connection to one of the elements among the end of the rails, 310 or 311, independent of the rail 106 and the end of the guide reliefs, 306 or 307, independent of the rail, the rod of the cylinder 806 being fixed to the other element.

[0226] Rails 310 or 311 support the shuttle and in particular the two profiles 312 supporting the attachment means 108.

[0227] Given the pivot joints implemented at the three vertices of the bracket, when the rod extends from the cylinder 806, the gripping means 108 undergo a counterclockwise rotation about the plane of Figure 13. When the rod of the cylinder 806 is retracted into the body of the cylinder 806, the gripping means 108 undergo a clockwise rotation about the plane of Figure 13.

[0228] This allows, in particular, for the separation of two attachment points and for fixing one of them first, then the other. This ensures better positioning of the attachment points.

[0229] Each attachment means 108 is fixed to a movable shuttle that translates along the Y-axis relative to the carriage. For example, the shuttle includes a plate and / or a profile 312 with a relief corresponding to the third rail, 310 and 311, to form a sliding connection along the Y-axis, the position of the shuttle relative to the third rails, 310 and 311 being controlled by the control unit 150.

[0230] To summarize, in the embodiments shown in Figures 1, 3 and 10:

[0231] - a mobile gantry, 104, 105, 302 and 303, forms a sliding link with an axis parallel to the X axis relative to the structure 101, whose position relative to the structure 101 is controlled relative to the control unit 150,

[0232] - a mobile carriage, 106, 306, 307, 310 and 311, forms a sliding joint with an axis parallel to the Z axis relative to the mobile gantry 104, 105, 302 and 303, whose position relative to the mobile gantry 104, 105, 302 and 303, is controlled relative to the control unit 150,

[0233] - a mobile shuttle 312 comprising the attachment means 108 forms a sliding link with axis parallel to the Y axis relative to the mobile carriage 106, 306, 307, 310 and 311, whose position relative to the mobile carriage 106, 306, 307, 310 and 311 is controlled relative to the control automaton 150.

[0234] In other embodiments, the X, Y and Z axes defining the sliding joints can be interchanged.

[0235] In some embodiments (not shown), the means of movement is a mobile articulated arm comprising the attachment means.

[0236] Water treatment module

[0237] Figure 9 schematically illustrates the treatments applied to the water and air used in device 100.11

[0238] Clean water, 605 and 607, is supplied either from a water network or from a dirty water treatment module 604. The clean water can be stored at ambient temperature in a so-called "cold" water tank 606 or in a so-called "hot" water tank 601. The water in the tank 601 is transferred 610 to a heat pump 115 by heat exchange with hot air 612 from at least one drying module 111 or from ambient air. The heated water 609 exiting the heat pump is returned to the hot water tank 601.

[0239] More generally, the heat pump 115 can be any means of heat exchange between a hot source and a cold source known to a person skilled in the art.

[0240] Hot water 602 from the hot water tank 601 is conveyed to at least one washing module 114 where the hot water is used to wash the laundry. Dirty water 603 is discharged to a dirty water treatment module 604. In this module, residues and waste 608 are filtered and / or treated and discharged, while clean water 605 and 607 is reused in the cycle described above.

[0241] Figure 9 also shows that outside air 618 is extracted and conveyed to a heating means 617. For example, such a heating means 617 is a resistor, a heat pump, and / or an infrared wave emitting heater. The heating means 617 can be any air heating means known to a person skilled in the art.

[0242] The hot air 616 from the heating means 617 is conveyed to a drying module 111 where it contributes to drying the laundry. The warm, humid air 614 is extracted from the drying module 111 by any means known to those skilled in the art. In some embodiments, the hot air 616 passes through several drying modules 111 before being extracted.

[0243] Between each drying module, the hot, humid air 614 is conveyed to a dehumidification means 613, for example a dehumidification membrane. The dehumidified hot air 612 is conveyed to the heat pump 115 to provide its thermal energy to heat the water in the hot water tank 601.

[0244] The dehumidified and cooled air 611 is then released into the atmosphere.

[0245] Additional modules

[0246] Device 100 may include at least one of the additional modules described below.

[0247] The device 100, which is the subject of the present invention, comprises a heating module 115, for example a heat pump. The heat pump is configured to use the thermal energy present in the air exiting the ventilation system of the dryer modules 111 to preheat the water before it enters a washing module 114.

[0248] Device 100 further includes a pumping module 113 configured to pump water from a preheated water tank to the washing module 114. Preferably, the pump is controlled by the control unit, which regulates the flow rate of the pumped water. Device 100 also includes an empty module 125, configured to allow the movement of a drum 109 towards a module. An empty module 125 is delimited by the structure 101.

[0249] The device 100 further includes a module 620 containing a detergent reservoir. Preferably, the module 620 includes a detergent level sensor that provides a representative value of the detergent level to the control unit 150. The module 620 may include a detergent pump configured to supply each washing module 114 with detergent. Preferably, the detergent pump is controlled by the control unit, which regulates the flow rate of the pumped detergent.

[0250] Control system and process

[0251] The device 100 includes a control unit 150 configured to control the mean movement 300 of at least one drum 109, at least one washing module 114 and / or at least one drying module 111.

[0252] It should be noted that, throughout this description, the term "automaton" means an automated system or a computer system or a set of automated systems and / or computer systems (for example, one automated system per function). In particular, the automated system 115 may include a human-machine interface 154, for example, a keyboard or a touchscreen, through which a user can give instructions to the control system 150.

[0253] Preferably, the automaton receives representative values ​​of physical quantities captured from the device, including:

[0254] - a water temperature in a washing module and / or in a preheated water tank,

[0255] - a drying temperature,

[0256] - a position of at least one drum 109 in a module,

[0257] - a quantity and / or flow rate of water, detergent or air,

[0258] - a position in an X, Y, Z coordinate system of a means of transport 300,

[0259] - a rotational drive speed of a drum 109,

[0260] - an image of the contents of a drum 109.

[0261] Preferably, the control system is configured to control:

[0262] - the means of displacement of at least one drum 109,

[0263] - the configuration of a 151 washing cycle of at least one 114 washing module,

[0264] - the configuration of a drying cycle 151 of at least one drying module 111,

[0265] - the activation of an electromagnet, such activation attaching a drum 109 by means of a hook 108,

[0266] - the deactivation of an electromagnet, such deactivation detaching a drum 109 from the attachment means 108,

[0267] - the commissioning of at least one water or air-driven washing pump, - the commissioning of at least one heating module 115,

[0268] - the opening and / or closing of a door of a washing module 114,

[0269] - the opening and / or closing of a diaphragm of an access module 112.

[0270] In preferred embodiments, the control unit 150 is configured to minimize the time required for washing and drying laundry in each drum 109.

[0271] In preferred embodiments, the control unit 150 includes a means for detecting an anomaly and a means for issuing an alert 152. For example, the anomaly may concern a water leak, overheating, loss of integrity of a drum 109, and / or vandalism. The alert issued may be visual and / or audible.

[0272] In preferred embodiments, the control unit is configured to associate the contents of a drum 109 with a user. For example, a user can identify themselves to the control unit using the human-machine interface 154. Such identification may involve reading at least one biometric data point of the user, defining a strong authentication method, or reading a card, for example, one equipped with a Near Field Communication (NFC) chip, a barcode, a two-dimensional code, a NFC chip, or an electronic chip assigned to the user. The unique identifier of the drum 109, then present in the withdrawal module 112, is then associated with the user's identification.

[0273] When the user-assigned drum 109 is placed in a retrieval module, the user must re-authenticate to access the drum 109's contents. The authentication process is similar to the embodiments described above. The access mechanism remains closed until the user is authenticated and / or identified.

[0274] Preferably, the 150 control unit is configured to verify the quality of a wash and / or dry cycle based on representative values ​​of measured physical quantities. In case of insufficient quality, a control unit is configured to implement a machine learning program to adjust the operating parameters of a wash and / or dry module to improve quality.

[0275] For example, when clothes are placed in the drum, a recording device, such as a camera, continuously captures a video stream representative of the clothes. This captured video stream is analyzed by a computer system embedded in the control unit (150) or a decentralized system. Such a computer system includes a machine learning program configured to detect and analyze at least one stain on at least one garment.

[0276] After the wash cycle, a representative video feed of the garments is captured and analyzed again by the computer system. For example, this step occurs when the garments are removed from the drum. The computer system analyzes the garments again to verify that each stain has been completely removed. The computer system then records the wash cycle configuration. If at least one stain remains, even partially, information to adapt the wash cycle is transmitted from the computer system to the control unit. For example, such information may command an increase in the wash cycle duration.

[0277] Preferably, at least one washing module 114 includes a water acidity sensor and / or a redox potential sensor (also called a "Redox sensor"). The water acidity and / or redox potential are preferably measured before detergent injection and during rinsing. Based on the water acidity, the computer system, equipped with a machine learning program, can determine whether the clothes are sufficiently washed and adapt the cycle accordingly.

[0278] In some embodiments, at least one removal module and at least one drying module each include a means for measuring the mass of the laundry. Preferably, when the laundry is placed in the drum 109, the mass of the laundry is recorded by the control unit 150. The control unit 150 compares the mass of dry laundry initially recorded to the mass of laundry measured by the measuring means in the drying module to determine whether the laundry is dry.

[0279] Preferably, the information recorded by the automated control system is shared with the computer system. The machine learning program is configured to learn and adapt the spin speed and drying time for subsequent cycles with similar garment material.

[0280] In some embodiments, the control unit 150 includes a means 156 for communicating at least one piece of information representative of the laundry in the drum 109 and / or the cycle applied to the laundry to the user. Such means are known to those skilled in the art and may involve the need to download an application onto the user's mobile phone as well as communication with a remote server. In some embodiments, each drum 109 includes at least one infrared sensor, for example, a multipoint infrared sensor.

[0281] Preferably, the computer system is configured to receive signals representative of the elements captured by the image capture device and / or the infrared sensor. The computer learning program is configured to analyze at least one signal and detect the presence of a living organism in drum 109.

[0282] For example, the machine learning program analyzes the image to detect if it contains an image of a living being (human or animal). If so, the image is compared with the infrared system to detect a thermal signature. If there is no thermal signature, the system deduces that it is an image on clothing.

[0283] In some embodiments, when the control system detects a malfunction resulting in degraded operation or a shutdown of at least one module, the machine learning program analyzes the problem and implements corrective actions to prevent recurrence. For example, in the event of premature wear of the transport mechanism or wear of the tank, the speed of movement or the rotation of the tank is reduced.

[0284] In these embodiments, the device 100 includes at least one wear sensor. Thanks to the sensors present on the device 100, a self-monitoring is performed periodically to check the overall wear condition of the device 100.

[0285] In some embodiments, the control unit 150 of the device 100 includes a means of communication 156 with a server and / or another control unit, the machine learning programs being fed with data from several control units.

[0286] For example, 100 devices in different geographical locations are interconnected via an IP and data-sharing system for improvement. Preferably, the computing system is decentralized. The results from the machine learning program are shared with at least one other 100 device communicating with the computing system.

[0287] Automatic laundry detection

[0288] In some embodiments, the device 100 includes a spectrometric analysis means 155 for the contents of the drum 109, the control unit 150 being configured to adapt an operating mode of a washing and / or drying module according to the result of the analysis carried out.

[0289] The spectrometric analysis means 155 includes, for example, a spectrum sensor configured to detect an infrared signature for each item placed in a drum 109. The spectrometric analysis means 155 is configured to compare the detected signature with a database associating an infrared signature with each textile in order to identify each textile in the drum 109. The comparison may implement machine learning.

[0290] The control system is configured to assign a washing and / or drying program based on the textiles detected.
