  • the washing drum 4 comprises in the outer surface of its ferrule, as means allowing rapid alignment of its door 10 with the access door 7 of the machine 1, an implementation of a manual rotation of this drum in a preferred direction, one or more oriented recesses formed by longitudinal recesses 14, 15, with asymmetrical V-shaped cross sections with respect to respectively radial planes of symmetry 16, 17 passing through the axis of rotation 6 of this drum 4 and the tops of these hollows.
  • the longitudinal hollow oriented in an asymmetrical V cross section 15 creates in the drum 4 to the left of the radial plane of symmetry 17 for an observer placing himself in the axis of rotation 6 of this drum, a bearing surface or oriented manual grip 21 facilitating manual rotation of this drum 4 in a direction opposite to that of arrow F, and to the right of this plane radial of symmetry 17, a surface 23 which allows fingers to slide easily and discourages manual rotation of this drum in the direction of arrow F.
  • direction indicators are reported formed or marked on the drum 4 near the hollows with asymmetrical V-section 14, 15 to make the preferential direction represented by the oriented manual sockets created in these hollows clearer. in a manual rotation of this drum during rapid alignment of the door 10 with the door 7.
  • This asymmetrical V-shaped recess 14 facilitates by its manual orientation 18, a manual rotation of the drum 4 in a preferred direction, that of arrow F and a rapid alignment of the gate 10 with the access door 7 after a short angular path of the drum 4 of the order of 90 ° and discourages by its sliding surface for the fingers 20 a manual rotation of this drum 4 in a non-preferential direction, that opposite to the arrow F where an alignment of the gate 10 with the door access 7 is obtained only after a long angular path of the drum 4 of the order of 270 °.
  • a washing machine 25 comprises an access door 26, a tank 27 and a washing drum 28 provided in the exterior surface of its shell with one part gate 30 and a longitudinal rib of the stirring 31, and on the other hand as means allowing, in a rapid alignment of its gate 30 with the access door 26 of the machine, a manual rotation of this drum in a preferred direction, of one or more oriented ribs formed by longitudinal ribs 33, 34 with asymmetrical inverted V cross sections with respect respectively to the radial planes of symmetry 35, 36 passing through the axis of rotation 37 of this drum and the tops of these ribs.
  • the longitudinal rib oriented with an asymmetrical inverted V cross section 33 created in the drum 28 to the left of the radial plane of symmetry 35 for an observer placing in the axis of rotation 37 of this drum 28, a bearing surface or manual grip oriented 39 facilitating manual rotation of this drum 28 in the direction of arrow G and to the right of this radial plane of symmetry 35, a surface 40 which easily allows fingers to slide and discourages manual rotation of this drum in a direction opposite to that of arrow G.
  • the longitudinal rib oriented with an asymmetrical inverted V cross section 34 creates in the drum 28 to the right of the radial plane of symmetry 36 for an observer placing in the axis of rotation 37 of this drum, a bearing surface or manual grip oriented 42 facilitating manual rotation of this drum 28 in a direction opposite to that of arrow G, and to the left of this radial plane of symmetry 36 a surface 44 which allows fingers to slide easily and discourages manual rotation of this drum in the direction of the arrow G.
  • direction indicators in the form of an arrow, an arrowhead or a chevron, etc. are attached, formed or marked on the drum 28 near the ribs oriented at asymmetrical inverted V cross sections 33, 34 to make clear the preferred direction of the oriented manual sockets 39, 42 created in these ribs in a manual rotation of this drum, during rapid alignment of the gate 30 with the access door 26.
  • the oriented rib with an asymmetrical inverted V cross section 33 is visible and accessible when the access door 26 of the washing machine is opened 25.
  • This oriented rib 33 facilitates by its manual grip oriented 39 manual rotation of the drum 28 in a preferential direction that of arrow G and rapid alignment of the gate 30 with the access door 26 after a short angular path of the drum 28 of the order of 90 ° and discourages by its sliding surface for the fingers 40, a manual rotation of this drum in a non-preferential direction that opposite to the arrow G where an alignment of the gate 30 with the access door 26 is obtained only after a long angular path of the drum 28 on the order of 270 °.

  • Each of the longitudinal recesses 52 creates a non-oriented or neutral manual grip for manual rotation of the drum 47 and the associated direction indicator 53 signals the preferential direction of this rotation of this drum to obtain after a short angular path of this drum, a quick alignment of the gate 50 with the machine access door 45.
  • a washing machine 55 comprises a tub 56 and a laundry drum 57 rotating around an axis of rotation 58.
  • the laundry drum 57 is provided in the outer surface of the ferrule, on the one hand with a door 60 and on the other hand as means allowing, in a rapid alignment of its door 60 with an access door not shown of the machine 55, an implementation of a manual rotation of this drum in a preferred direction, of at least two longitudinal recesses with a U or V symmetrical cross section 63, 64 or two longitudinal ribs with a U or V cross section inverted symmetrical with respect to the radial planes passing through the axis of rotation 58 of this drum and the tops of these hollows or ribs, each located in one of the cylindrical halves of this drum and angularly offset one or the other by relative to each other on the cylindrical surface of the shell of this drum, and two preferred direction indicators such as chevrons 65, 66, associated respectively with these two recesses 63, 64 or ribs.
  • the manual sockets 63 and 64 are oriented and such that they facilitate rotation of the drum 4 in one direction and discourage it in an opposite direction. Preferential direction indicators may possibly be associated with these sockets.
  • the hollows and ribs formed in a washing machine washing drum and serving as manual sockets facilitating manual rotation of this drum in a preferred direction, and the direction indicators signaling this preferred direction which constitute means for implementing a rapid alignment of a door of this drum with an access door of this machine, described in the above paragraphs are easy to carry out, simple, solid and reliable in their operation, and therefore make this washing machine efficient in its use and economical in its manufacture.
