Abstract
Description
Title of the invention: LAUNDRY WASHING AND DRYING DEVICE Technical field of the invention
[0001] 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. State of the art
[0002] Currently, to wash their clothes, a user can use an individual appliance or a shared laundromat. If the user owns an individual appliance, they may have a washing machine, a dryer, or a washing machine that also performs drying. However, individual machines are energy-intensive because they do not allow for optimized thermal operation.
[0003] 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 recovery.
[0004] Automated laundry systems exist as described in French patent application FR 2 824 339 AL. However, these systems are very bulky, as they require a significant operating space. Each drying or washing module is associated with an arm that retrieves a drum from a storage space. 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 base of the drum and the shaft to withstand the stresses exerted during washing or drying.
[0005] Similarly, French 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 implies additional space for positioning this shaft as well as a robust coupling means between the base of the drum and the shaft to withstand the stresses exerted during washing or drying.
[0006] These systems are therefore not compact, are energy-intensive and require highly complex means to position and then operate the drums. Summary of the invention
[0007] The present invention aims to remedy all or part of these drawbacks.
[0008] It proposes a modular automatic laundry system in which the drum axis is maintained in a substantially horizontal plane. The drum is moved from module to module and driven in rotation by a gearing system located on its periphery, which maximizes the compactness of the device. Brief description of the figures

Description of the implementation methods
[0010] The present description is given by way of non-limiting grammar, each feature of an embodiment being able to be advantageously combined with any other feature of any other embodiment.
[0011] The expression "and / or", as used in this document, shall 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" shall be interpreted in the same way, that is, "one or more" of the elements thus joined. Other elements may also be present, other than 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.
[0012] 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.
[0013] We call: - "access side", which is shown in the background of figures 1, 4 to 8 and 10 and in the foreground of [Fig.3], - “technical side” which is represented in the foreground of figures 1, 4 to 8 and 10 and in the background in [Fig.3], - "left" which is represented on the left of figures 1, 4 to 8 and 10, in the background of [Fig.2] and on the right of [Fig.3], - "right" which is represented on the right of figures 1, 4 to 8 and 10, in the foreground of [Fig.2] and on the left of [Fig.3].
[0014] 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.
[0015] Three orthogonal axes X, Y, and Z are defined here. The Z axis is vertical when the device of the present invention is in normal operating conditions. The X and Y axes are horizontal axes when the device of the present invention is in normal operating conditions. The Y axis extends from the access side to the technical side. The X axis extends along the access side.
[0016] We observe, in [Fig.1], a washing and drying device for laundry 100 which is the subject of the present invention.
[0017] Drum
[0018] The device 100 comprises at least two movable drums 109, shown in figures 2 and 3.
[0019] A movable drum 109 has a cylindrical shape 201 with a hollow circular base 202 and 203. The movable 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.
[0020] Preferably, the drum 109 has, at least in part, a coating of ferromagnetic material. For example, the cylinder 201 is made of ferromagnetic material, such as stainless steel.
[0021] 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 of laundry mixing, known to those skilled in the art, on the surface facing the inside of the cylinder 201.
[0022] The drum 109 is equipped with an external radial engagement means 205. 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 toothed wheel 205 defining an axis of rotation YT of the drum 109.
[0023] Preferably, the gear 205 is placed at a distance from the base 202 less than or equal to half the distance between the bases, 202 and 203, along the YT axis. Even more preferably, the gear 205 is placed at a distance from the base 202 less than or equal to one-quarter of the distance between the bases, 202 and 203, along the YT axis. Still more preferably, the gear 205 is attached to the base 202.
[0024] The gear 205 preferably has straight teeth to transmit the same torque, regardless of the direction of rotation imposed on the drum 109.
[0025] 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.
[0026] Preferably, the drum 109 has a tread 204 near the bottom 202 and a tread 206 near the base 203.
[0027] 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 can be at least one door (not shown) for example mounted on a hinge with axis of rotation in a plane normal to the YT axis.
[0028] In preferred embodiments shown in [Fig.3], the means of accessing the contents of a drum by a user includes a diaphragm actuated by a toothed wheel 207 positioned on the periphery of the drum 109, for example made in a similar manner to a camera diaphragm, but of different dimensions.
[0029] Such a diaphragm is shown in [Fig. 3] and comprises at least two blades 209 mounted for rotation about a gear 207. The gear 207 is mounted around the base 203, which rotates with the cylinder 201 of the drum 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.
[0030] 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 being fixed to 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.
[0031] 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.
[0032] Actuating the gear 207 causes the blades 209 to rotate, and the engagement of the lugs 208 in the respective grooves 211 results in the radial movement of the blades. As shown in [Fig. 3], counterclockwise rotation of the gear 207 about the axis YT causes the diaphragm to close. Conversely, clockwise rotation of the gear 207 about the axis YT causes the diaphragm to open.
[0033] In the embodiment shown in [Fig. 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.
[0034] 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 running from the access side to the technical side of the device, represented by the Y axis in [Fig. 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.
[0035] Preferably, each drum 109 of the device 100 includes a unique identification means. Such a unique identification means is, for example, an RFID chip bearing a unique identifier. Preferably, in order to avoid supplying electrical power to the drum 109, the RFID chip is passive.
[0036] Drying module
[0037] The device 100 comprises at least one drying module 111 shown in [Fig.6]. In the embodiment shown in [Fig.1], the device 100 comprises five drying modules.
[0038] Each drying module 111 comprises: - a drive means 408 for rotating said drum 109 configured to couple with the engagement means 204 of said drum 109; and - a means of drying 404 of the contents of the drum; 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.
[0039] Inside 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 comprises at least one infrared emitting lamp. Preferably, each infrared emitting lamp is positioned on an edge of the sealed enclosure 401 to limit the overall size of the drying module.
[0040] 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.

[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] Preferably, the door is mounted such that its movement is maintained in a plane perpendicular to the Y-axis. For example, the door is mounted to translate along an axis, for example the vertical Z-axis. The sliding connection is achieved by any means known to those skilled in the art. For example, a rack is fixed to the door and a toothed wheel is driven to cause the door to move along the axis defined by the rack.
[0048] In 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.
[0049] In embodiments, each sealed enclosure 401 is equipped with a moisture filtration means, preferably self-cleaning.
[0050] Washing module
[0051] The device 100 comprises at least one washing module 114 shown in figures 7 and 8. In the embodiment shown in [Fig.1], the device 100 comprises two washing modules 114.
[0052] Each washing module 114 comprises: - a means for rotating a drum 109 configured to couple with the engagement means 204 of said drum; - a means of washing, 505, 506, 507, the contents of the drum.
[0053] The means for rotating the washing module is similar to the means for rotating the drying module described above.
[0054] The washing module includes a structure 501 configured to support a washing tank 505. The structure 501 is, for example, made of metal profiles welded, 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 has 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.
[0055] 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 part 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.
[0056] Preferably, the fixed part 505 of the tank consists of half of the cylinder trunk between the opening plane and the ground, and the entirety of each base of the cylinder. The fixed part 505 of the tank is attached to the structure 501 in the opening plane.
[0057] The water inlet 506 preferably comprises a plurality of orifices uniformly distributed on 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 part of the tank.
[0058] 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.
[0059] The water inlet 506 is connected to a water supply pipe 511.
[0060] The dirty water outlet 507 preferably has a plurality of orifices uniformly distributed on the side with the plane of symmetry opposite to the side containing the water inlet 506. 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 washing tank. Such positioning makes it possible to simulate a water flow in the tank and to obtain better washing performance for the laundry.
[0061] Given the position of the plane of symmetry, the washing module includes the clean water inlet 506 and detergent, and the dirty water outlet 507 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.
[0062] The water inlet 506 is connected to a water drain pipe 512.
[0063] The water cycle is described below with reference to [Fig.9].
[0064] 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 form a sealed unit.
[0065] 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.
[0066] The leaves 503 are preferably formed of the same material as the fixed part 505.
[0067] Each reinforcement 502 is assembled by a pivot joint with 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.
[0068] 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.
[0069] 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.
[0070] 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.
[0071] Preferably, each flap 503 covers, at least partially, an opening positioned zenithally. In the embodiments shown in [Fig. 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] Preferably, each beater 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.
[0076] On the doors, the supports 509 are positioned opposite a reinforcement 502 with respect to the leaf 503. This allows the forces to be transmitted directly from the supports 509 to the reinforcements 502 along a radial axis.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] 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 rollers 510.
[0081] The means for driving the washing module corresponds to the embodiments of the means for driving described in relation to figures 5 and 6 concerning the drying module.
[0082] 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.
[0083] On [Fig.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.
[0084] Storage module
[0085] The device 100 may include at least one storage module 112 shown in [Fig. 1]. Preferably, the 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 within the framework of optimizing a user management flow. Each deposit or retrieval module has an opening on the access side. The device 100 must include one of the following modules: a deposit or retrieval module and may to also include 112 storage modules for clean and dry linen, without openings on the access side.
[0086] Each deposit or withdrawal module includes: - a means for receiving a drum 109; and - a means of actuating the access means, 208 to 211, to the contents of the drum 109.
[0087] In preferred embodiments, each deposit or withdrawal module further comprises a means of rotating said drum 109 configured to couple with the engagement means 204 of said drum 109.
[0088] 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.
[0089] The addition of a drum 109 drive means 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.
[0090] The drum receiving means has a fixed frame configured to be fixed on the structure 101. Preferably, the fixed frame has guide wheels 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.
[0091] Structure
[0092] The device 100 comprises a structure 101 defining a set of rectangular parallelepipeds, each parallelepiped being configured to receive a module from among a washing module 114, a drying module 111 and / or a storage module 112.
[0093] 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.
[0094] Preferably, each structural cell corresponding to a module configured to receive a drum 109, is a rectangular parallelepiped of which: - 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 - 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.
[0095] 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.
[0096] 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 be different from those defined above.
[0097] The device 100 therefore defines a matrix of modules represented schematically in [Fig. 10]. In [Fig. 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.
[0098] The row of modules along the Y axis furthest from the access side comprises a single line of modules closest to the ground comprising, from left to right, a detergent tank module 604, a washing module 114 and a heating module 115.
[0099] The row of modules along the Y axis closest to the access side comprises four rows of modules superimposed along the Z axis.

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.
[0124] 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.
[0125] Hot water 602 from the hot water tank 601 is conveyed to at least one washing module 114 in which the hot water is used to wash the laundry. The dirty water 603 is discharged to a dirty water treatment module 604.

[0138] It should be noted that, throughout the description, the term "automaton" means an automaton or a computer system or a set of automata and / or computer systems (for example, one automaton per function). In particular, the automaton 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 automaton 150.
[0139] Preferably, the automaton receives representative values of physical quantities captured from the device, in particular: - a water temperature in a washing module and / or in a preheated water tank, - a drying temperature, - a position of at least one drum 109 in a module, - a quantity and / or flow rate of water, detergent or air, - a position in an X, Y, Z coordinate system of a means of movement 300, - a rotational drive speed of a drum 109, - an image of a content of a drum 109.
[0140] Preferably, the control system is configured in particular to control: - the means of displacement of at least one drum 109, - the configuration of a washing cycle 151 of at least one washing module 114, - the configuration of a drying cycle 151 of at least one drying module 111, - the activation of an electromagnet, such activation attaching a drum 109 by means of an attachment 108, - the deactivation of an electromagnet, such deactivation detaching a drum 109 from the attachment means 108, - the activation of at least one water or air washing pump, - the activation of at least one heating module 115, - the opening and / or closing of a door of a washing module 114, - the opening and / or closing of a diaphragm of an access module 112, In preferred embodiments, the control unit 150 is configured to minimize the time required for washing and drying the laundry in each drum 109.
[0141] 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 relates to a water leak, overheating, or a loss of integrity of a drum 109 and / or vandalism. The alert issued may be visual and / or audible.
[0142] 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, reading a card, for example, equipped with a near-field communication (NFC) means, a barcode, a two-dimensional code, a near-field communication 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.
[0143] When the drum 109 assigned to the user is positioned in a retrieval module, the user re-authenticates in order to access the contents of the drum 109. The authentication is similar to the embodiments described above. As long as the user is not authenticated and / or identified, the access means remains closed.
[0144] Preferably, the control unit 150 is configured to verify the quality of a wash and / or dry 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 function parameters of a wash and / or dry module to improve quality.
[0145] For example: when the clothes are placed in the drum, a recording device, for example a camera, continuously captures a video stream representative of the clothes. The captured video stream is analyzed by a computer system embedded in the control unit 150 or decentralized. Such a computer system includes a machine learning program configured to detect and analyze at least one stain on at least one garment.
[0146] After the wash cycle, a representative video feed of the garments is again captured and analyzed 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.
[0147] If at least one task persists, at least partially, information to adapt the washing cycle is transmitted from the computer system to the control unit. For example, such information commands an increase in the duration of the washing cycle.
[0148] 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.
[0149] In 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 that the laundry is dry.
[0150] Preferably, the information recorded by the control unit 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.
[0151] 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.
[0152] 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 being in the drum 109.
[0153] For example, the machine learning program analyzes the image to detect whether an image of a living being (human or animal) is detected; 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.
[0154] 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 measures to prevent the problem from recurring. For example, in the event of premature wear of the means of transport, or wear of the tank, the speed of movement or rotation of the tank is reduced.
[0155] 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.
[0156] In some embodiments, the control automaton 150 of the device 100 includes a means of communication 156 with a server and / or another control automaton, the machine learning programs being fed with data from several control automata.
[0157] For example, 100 devices at different geographical locations are interconnected by an IP and data-sharing system for improvement. Preferably, the computer system is decentralized. The results from the machine learning program are shared with at least one other 100 device communicating with the computer system.
[0158] Automatic laundry detection
[0159] In embodiments, the device 100 includes a spectrometric analysis means 155 of 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.
[0160] The spectrometric analysis means 155 includes, for example, a spectrum sensor configured to detect an infrared signature for each article deposited 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 determine each textile in the drum 109. The comparison may implement machine learning.
[0161] The control unit is configured to assign a washing and / or drying program based on the textiles detected.
[0162] Benefits provided
[0163] According to a first aspect, the present invention relates to a laundry washing and drying device, which comprises: - at least two movable drums equipped with a radial external engagement means, - at least one washing module, comprising: - a means for rotating said drum configured to couple with the means for engaging said drum; - a means of washing the contents of the drum, - at least one drying module, comprising: - a means for rotating said drum configured to couple with the means for engaging said drum; and - a means of drying the contents of the drum; - at least one means of moving a drum comprising a means of attaching to the drum and configured to move the drum from one module to another and - a control automation system configured to control the means of moving at least one drum, at least one washing module and / or at least one drying module.
[0164] Thanks to these arrangements, the drum axis is maintained in a substantially horizontal position at all times, regardless of its orientation. Furthermore, since the drum is equipped with an external radial engagement means, and each module couples with the engagement means to drive the rotating drum, the compactness of the device increases.

[0181] In 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.
[0182] Thanks to these arrangements, the device does not require a door that opens by rotating around a hinge, thus further reducing the device's compactness.

These embodiments also prevent the loss of some of the drum's contents during its movement.
[0183] In 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.
