- each rod 61 consists of a stainless steel wire and is elastically deformable. Since the manipulator 9 positions each drum 2 in the module 5 with a random angular orientation, the rotation of the drum 2 generally requires a prior rotation of the plate 58 relative to the drum 2, so as to engage the rods 61 with slits 25 of the drum 2.

- Each plug 230, 240 further comprises a peripheral rim 236, 246, whose frustoconical profile allows it to cooperate with that of a corresponding centering cone 229. Finally, the rim and the hub are connected by spokes 238 and 248, for example six in number.
- the removable cap 230 is fixed on the centering cone 229 opposite, by any appropriate means such as, for example, a ball bushing.
- a grid 211 which covers in particular the inner face of the plugs 230 and 240, as visible in Figures 18 and 19.
- the grid 211 closes the two end ends 202A and 202B of the drum 202.
- This grid 211 defines front orifices 213, intended for the passage of drying air, as will be seen in what follows.
- the transverse dimension of each of these orifices 213 is substantially greater than that of the wiping openings 209 mentioned above.
- these air passage holes have a transverse dimension of between 0.5 and 1 centimeter.
- a washing and drying module 205 which comprises a tank 250 for receiving one of the drums 202, for washing and drying the laundry it contains.
- This tank consists of a base 251, and a cover 252, movable relative to this base (see in particular Figures 14 to 17).
- this cover is provided in particular by two arms 255 and 256, pivotally mounted on the module frame. These arms 255 and 256, which are tubular, have free ends 255- ⁇ and 256i which are directed towards one another. In their middle part, next to the hubs 232 and 242, each arm supports an ogive 265, 266, adapted to penetrate into a corresponding housing 234, 244.
- Each warhead is integral with the arm which supports it, in translation, but is free to pivot relative to this arm about a geometric axis, substantially parallel to that of the drum.
- One 265 of the warheads is rotated by a geared motor 257 while, as will be seen in what follows, the other warhead 266 is adapted to be rotated under the effect of the actual movement of the drum.
- the mechanical axis of the arm carrying the geared motor drives the nose 265 by embedding, while the ogive 266 is secured to a guide axis, carried by the non-motorized arm.
- the cover 252 is secured to two longitudinal members 260 adapted to be driven by belts 262, mounted on the frame. These longitudinal members 260 define two pairs of stops, for guiding the arms 255 and 256 during their pivoting movement. 264 'denote the two adjacent abutments, called inner, and 264 "the two opposite stops, said outer.
- springs 270 are interposed between the frame and the walls facing the base 251. These springs first allow some movement of the base relative to the floor of the room. In addition, they allow a pressure of the base against the cover, for their mutual sealing, which corrects any manufacturing defects.
- the plug 230 rotated by the nose 265, in turn drives the casing of the drum, which is itself secured to the other plug 240.
- the latter finally causes the second warhead 266, which is integral with the axis of the non-motorized arm, as seen above.
- This axis can be equipped with a tachometer, to check the agreement with the drive gear motor. This makes it possible to detect a possible defect, such as the absence of the drum in the tank, or the blocking of the drum.
- the motor 257 is stopped. Then, the belts 262 induce an upward movement of the longitudinal members 260, as well as the cover 252, which is consequently disengaged with respect to the base 251. At a certain stage of this movement the inner stops 264 'push the free ends of the arms 255 and 256 away from each other.
- the user removes the removable cap, places his soiled laundry in the inner volume of the drum, then restores the aforementioned cap.
- the manipulator then disposes the drum against the base 251, the cover being in its raised position described above.
- the belts 262 then lower the longitudinal members 260 and the cover 252.
- the outer stops 264 "push the arms 265 and 266 towards each other. warheads in the direction of the drum, so that these warheads immobilize again in the housings 234 and 244, defined by the hubs of the caps.
- the drum drive is implemented particularly robustly, because of the "peak" of warheads and hubs.
- the arms 255, 256 are symmetrical and tubular in nature, which allows a particularly simple design and implementation.
- the respective drying and drying phases are processed separately at the drum.
- the water is discharged by centrifugal force according to the arrows F1, only through the openings 209 of small dimensions of the envelope 221.
- This small size is advantageous because it avoids the laundry , materialized by the reference L, to exceed perforations, which strongly reduces the risks of deterioration of the linen.
- the orifices 213 formed in this mesh are likely to have relatively large dimensions, which allows a satisfactory air passage from behind to the drum during the drying phase.
- the air path during this drying phase is indicated by the arrows F2.
- the arrangement of the modules and the manipulator inside the automaton may be different from those presented in the first and second embodiments.
- the storage module may be circular in shape, the circulation corridor of the manipulator then also being circular.
- each drum can have a different orientation in the loading module and inside the automaton, the cradle of the loading module then being provided to apply a rotation adapted to the drum.
- the automaton may comprise a separate loading module and a separate unloading module, so as to eliminate any risk of crossover between soiled laundry and the clean linen. Two separate storage shelves are also provided, one being reserved exclusively for storing drums containing soiled laundry, while the other is reserved exclusively for storing drums containing clean laundry.
- an automaton according to the invention can comprise several modules of each type described for the PLCs 1,
