Definitions

  • the present invention relates to a top-loading washing machine having a drum with a peripheral wall formed with an opening for the passage of the laundry, said opening being provided with a door adapted to close such opening.
  • the drum of the majority of top-loading washing machines has a door made by two flaps adapted to partially overlap one another and hingedly mounted on opposite rims of the drum opening by means of springs adapted to bias them towards their open position.
  • Such door flaps are provided respectively with hooks and engagement openings cooperating with one another for locking the flaps in their closed position.
  • a top-loading washing machine having a door in a single piece is disclosed in EP-A-869212 in which the door is pivotally mounted to the spin drum so as to pivot about the centre axis of rotation of the drum. Even if this solution does simplify the way in which the door is opened by the user, nevertheless this system is quite complex, expensive and needs a proper balancing of the door.
  • EP-A-0959169 and EP-A-0681050 disclose a top-loading machine where the simple piece door is hinged to the drum.
  • GB 134659 A and DE 1815020 U disclose simple piece doors for top loading machines in which the door is provided with spring loaded latches.
  • US-A-3226961 discloses a washing machine according to the preamble of claim 1. According to the present invention, the above disadvantages are overcome thanks to the features listed in the appended claims.
  • the door of the drum comprises a single flap having a first end hingedly mounted on a first rim of the opening. Snap-engagement means for locking and unlocking the door are provided between a second end of the flap, opposite to its first end, and a second rim of the opening. In this way the user has to handle only one flap.
  • the snap-engagement means comprise a latch element slidable on the second end of the flap and hook elements on the corresponding second rim.
  • a top-loading clothes washing machine comprises a tub 10 that is adapted to be suspended in a frame (not shown).
  • a drum 12 having a horizontal axis is rotatably mounted and it is provided, on its peripheral cylindrical wall 12a, with an opening 14 for loading and unloading clothes items.
  • the drum 12 comprises also two opposing end walls 12b, and the opening 14 has two opposite rectilinear rims 14a and 14b respectively.
  • a door 16 made by a single curved flap is hinged to a first rim 14a of the opening 14, and springs 18 are coaxially mounted on the hinge in order to bias the door 16 towards its open position shown in figure 1.
  • the second rim 14b of the opening 14 is provided with a plurality of mushroom-shaped pins 20 projecting outside the drum.
  • Each pin 20 has a base portion 20a fixed to the drum, and an enlarged tapered end portion 20b, adapted to cooperate with corresponding holes 22a provided in a sliding latch 22 carried by an edge 16a of the door 16.
  • the latch 22 is slidably mounted in a seat 24 defined by the wall of the door and by a cover 26 fixed in 28 to the door (figure 3).
  • the cover 26 is not shown in figures 1 and 4.
  • the cover 26 present a plurality of dome portion 26a in correspondence to the position of the holes 22a, and it has the main function to avoid any entanglement of laundry items with the pins 20 during loading and unloading of the drum 12.
  • an axial spring 30 which urges the latch toward a side end position, as shown in figure 4.
  • the latch 22 is also provided with a trigger 32 sliding in a corresponding slot of the cover 26 in order to allow the user to slide the latch 22 against the action of the spring 30.
  • the closure of the door 16 is very easy for the user. He has only to urge the door 16 against the actions of the springs 18 up to a position shown in figures 4 and 5, where the latch 22 is in contact with the tapered end portions 20b of the pins 20. A further small rotation of the door 16 urged by the user causes a snap-engagement of the pin 20 in the corresponding holes 22a of the latch 22 (as shown in figure 6). In this configuration the washing machine can start its washing program. For opening the door 16 the user needs only to act on the trigger 32 so that the latch 22 is disengaged from the pins 20. The springs 18 do the rest.
  • the latch 22 is provided with an end E which can be driven automatically by a device (not shown) in order to open automatically the door once the user open the lid of the washing machine.
  • a device can be mechanical (for instance driven by the opening movement of the lid) or electromechanical (for instance driven by a switch that senses when the lid is opened by the user).
