Definitions

  • the present invention refers to a door for front-loading washing machine.
  • Front-loading washing machines comprise a unit having a tub comprising a drum, normally with horizontal axis; the drum has an opening for loading the laundry to be washed which is aligned with the opening of the unit. Said opening is closed by an openable door hinged to the unit.
  • the door is generally shaped like a porthole and comprises a transparent glass part with a plastic frame.
  • the door has a ring-shaped seal which, once the door has been closed, presses up against the edge of the opening to prevent water and detergent coming out during washing.
  • the glass part of washing machine doors is a recess shaped so as to keep the laundry inside the washing drum and prevent the laundry being damaged during washing or spin-drying operations.
  • the object of the present invention is to provide a door for front-loading washing machines that upgrades the washing action of the washing machine itself.
  • the washing machine preferably a laundry washing machine
  • the washing machine has in a known way a unit 1 comprising a front panel 9 having an opening 2 for loading the laundry to be washed, a washing tub fitted inside the unit and containing a drum fitted inside the tub in a revolving way and the drum and the tub (not visible in the illustrations) have respective openings aligned the one with the other and with the opening of the unit.
  • the opening 2 of the unit 1 is closed by a door 3 hinged in 4 to the unit 1.
  • the door 3 is of the porthole type and comprises a circular frame 31 and an inner part 32, preferably in glass.
  • the inner part 32 comprises a central part 33 with a convex part 33 adjacent to two concave parts 34. More precisely, the inner part 32 of the door 3 is shaped so that the horizontal section passing through the centre C of the door ( figure 3 ) comprises the convex part 33 arranged at the centre of the inner part 32 and the concave parts 34 adjacent to the part 33; the concave parts 34 connect up on one side with the convex part 33 and on the other side with a circular peripheral part 35 of the door 3. Said shaping of the inner part 32 stretches vertically for at least half the height H of the door 3.
  • the convex part 33 has a lower horizontal extension than each concave part 34; the concave parts 34 preferably have the same horizontal extension.
  • the circular peripheral part 35 is adjacent to and integral with the frame 31.
  • the circular peripheral part 35 has a shape identical to that of the known doors; this way it is not necessary to change the joint of the opening of the washing machine that presses up against the door 3 and more precisely with the circular peripheral part 35 of the door 3. This way, the door 3 can be used for any type of front-loading washing machine.
  • the inner part 32 of the door is shaped symmetrically with respect to the vertical axis A passing through the centre C of the door 3.
  • the convex part 33 protrudes further from the inner profile P of the door than do the concave parts 34, i.e., it has a greater depth of the concave parts 34 with respect to the profile P on the side of the door which, with the door closed, is fitted inside the opening 2.
  • the profile P is a vertical axis passing through the inner part of the frame 31 of the door P, i.e., the part of the frame 31 that presses up against the front panel of the unit 1 when the door 3 is closed.
  • the convex part 33 stretches along the vertical axis A passing through the centre C of the door 3 while the concave parts 34 connect up with said convex part 33 and with the circular peripheral part 35 of the door.
  • the door therefore has a double involute symmetric with respect to the central axis A.
  • the door 3 allows a greater revolution action of the laundry load acting on the involute surface of the porthole door.
  • the result is a greater twisting of the laundry which wraps up in partial rotation and slips on the parts 34 of the door by means of a movement with direction shown by the arrows F in figure 5 ;
  • the rotary movement of the laundry is substantially crossways to the typical rotary movement of the washing-machine drum. Said rotary movement of the laundry according to the arrows F combined with the typical rotary movement of the drum helps ensure more effective laundry washing.
  • the inner part 32 of the door is furthermore shaped asymmetrically with respect to the horizontal axis B passing through the centre C of the door 3 ( figure 2 ).
  • the upper part 36 has a different shape with respect to the lower part 37.
  • the convex part 33 arranged centrally and adjacent to the two concave parts 34, connects up with the upper extremity 38 of the circular peripheral part 35 by means of a concave part 39.
  • the particular shape of the upper part 36 helps increase the effectiveness of the rotary movement according to the arrows F of the laundry load in the drum.
