Definitions

  • the present invention relates to a machine for the washing and/or drying of laundry comprising:
  • front loading washing machines are supplied with a door, generally of a circular shape, through which the user can have access to the inside of the basket of the machine, for the normal laundry loading and unloading operations.
  • a door or port
  • Such door, or port is generally hinged to the cabinet of the machine by means of a hinge comprising a fixed part, internally secured to the body of the machine, and a mobile part, integral to the door; the fixed and mobile parts have mutual hinging means according to a substantially vertical axis.
  • the mobile part of the hinge has an arched portion, having a curvature axis substantially coinciding with the vertical axis mentioned above: such arched portion extends, and is mobile, through a substantially vertical slot, being part of the fixed part of the hinge, and through a corresponding slot obtained on the cabinet of the machine.
  • a first problem is due to the fact that, according to the cited known art, the hinge is internally fixed to the cabinet, which is not simple or fast, and determines a certain bulk within the cabinet itself.
  • laundry washing machine doors have a shaped glass front, that extends in a manner being considerably pronounced towards the interior of the cabinet: another problem is that the hinges of the described type do not allow for obtaining in machines with flush doors a level of opening that consents the complete release of the loading door: in such machines the bulk determined by the glass of the door can be a hindrance during the operations of loading/unloading laundry.
  • Still another problem with the machines according to the known art is that, when the door is opened, there is the risk that it may strike the cabinet of the machine, with the risk of damage.
  • the aim of the present invention is that of solving the aforementioned problems and in particular to indicate a machine for the washing and/or drying of laundry equipped with front loading door, substantially flush with the frontal part of the cabinet, which is hinged to the machine cabinet by means of a hinge being simple, functional, reliable, low-cost and of a good aesthetic appearance.
  • a machine for the washing and/or drying of laundry comprising:
  • an element of the fixed hinge which becomes secured in use to the exterior of the cabinet of a washing machine, for instance by way of a series of through screws inserted in holes 2; the hinge element 1 has a pair of forked supports 3 within which hinging pins 4 and 5 are inserted; such pins 4 and 5 are used for the hinging of three couplers or leverage arms.
  • pins 4 are used for pivoting in the two supports 3 the non oscillating extremities of the two external arms 6, also visible in figure 3, both being identical; pin 5 on the other hand is utilised for pivoting the non oscillating extremity of an internal arm 7, curved, which is arranged between the two supports 3, the oscillating extremity, being fork shaped, of such arm 7, such as that of the arms 6, is hinged to the door or circular port of the washing machine.
  • the seat 11 centrally has a hooking portion 14, equipped with a through hole 15, the overall size of which being such to be inserted between the two arms (7A) of the fork that constitutes the oscillating extremity of the arm 7; the hooking portion 14 is pivoted to the forked oscillating extremity of the arm 7 by way of a pin 16.
  • the frame 10, and therefore the door of the washing machine according to the invention are assembled as is seen in figure 4, in which the door is seen in the opened position; from such figure it is also possible to understand how the shaping of the seat 11 has been chosen of more or less a complementary form of the element 1 and of the arms 6 and 7, in such a way that, upon closing the door, the two forms join together, thus determining a greatly reduced encumbrance of the hinge.
  • the washing machine according to the present invention has a hinge constituted by a articulated quadrilateral comprising a fixed portion (hinge element) and a mobile portion (shaped seat 11 of the frame 10), the first being fixed to the cabinet of the machine and the second being part of the door, the two portions being connected and articulated by means of three couplers or arms 6 and 7.
  • the distance that takes place between pins 4 and 13 is lower than the distance that takes place between pins 5 and 16, as the arms are of different lengths, for which, in particular, the articulated quadrilateral is irregular; by way of such articulated quadrilateral it is therefore possible to obtain a movement, of the type in itself known, rotary and translational of the door, during the opening and closing phases of which.
  • the positions assumed by the hinge at the beginning and end of such rotary-translational movement are visible in figure 5 and, still cleared by comparing the figures 6 and 7.
  • 20 indicates the frontal wall of the cabinet of the machine according to the invention
  • 21 indicates a recess apt at containing the bulk of the hinge 10 and the hinging element 1
  • 22 indicates the glass of the door
  • 23 indicates a bellows type seal, normally present between the loading aperture of the washing machine and the central opening of its basket; with the letter A the loading aperture of the machine is indicated.
  • the hinging element 1 can be fixed from the outside to the frontal wall of the cabinet, inside the recess 21 and as the door is however substantially flush with the frontal wall 20 of the cabinet of the machine.
  • a further substantial advantage to be considered is that the contained dimensions of the fixed hinge element 1 and the corresponding shaping of the seat 11, that constitutes the mobile element of the hinge, allow for reducing to a minimum the overall dimensions of the hinge, which thus results in being simply housed within the recess present around the loading aperture of the washing machine.
  • the hinge represented in such figures is in fact supplied with only two arms, visible with 30 and 31; the non oscillating extremities of such arms 30 and 31 have their fulcrum at the fixed element of the hinge 1' by way of pins 33 and 34, whilst the oscillating extremities of the same are pivoted to the mobile element of the hinge (the seat 11' obtained within the frame 10') by way of pins 35 and 36.
  • figure 8 By comparing figure 8 (door closed) with figure 9 (door open) it is possible to notice the positions reached by the hinge at the beginning and at the end of its rotary-translational movement; in particular from figure 9 it is possible to notice how, according to the proposed variant, the stop of the angular opening of the hinge is directly obtained by way of two arms 30 and 31.
