Definitions

  • the present invention relates to the production of components for electrical household appliances and the like.
  • the invention concerns a two-stage hinge device for the door of electrical household appliances, particularly for washing machine, fit to allow a double joint between the door and the body of the related appliance so that to realize an opening-closing system in two phases.
  • hinge is positioned sideways with respect to the opening carried out in the electrical household appliance body and fit to be closed by the relative door, in such a way to allow a side rotation of the same door during the opening/closing operation.
  • the known hinge devices include a connection element constituted by a shaped plate extending longitudinally along a main axis, fixed to the appliance frame and having a support element fixed to the door hinged to a pivot parallel to the main axis.
  • the known hinges devices connected to the related door allow an opening condition with an angle of around 90-100 degrees in comparison with the closing position.
  • the main drawback of the known hinge devices is that with said opening angle the opened door is protruding from the washing machine body and generally is in the way, particularly when this electrical household appliance is put in narrow spaces.
  • the opened door limits the load operations of the laundry to be washed, hampering particularly the user movements.
  • the known hinge devices need a support element having dimensions particularly elongated and curved in such a way to guarantee the free opening of the door without interfering with the structure of the washing machine, particularly close to the hinge.
  • An adopted compromise is then to move forward the door in comparison with the washing machine wall, that is to install hinge devices such that the frontal wall of the door, in correspondence of the closing position, protrudes from the frontal wall of the washing machine body, in which the water tightness is guaranteed by a gasket having often large sizes.
  • Said solution has some drawbacks such as the increasing of the washing machine dimensions, sometimes with protrusions that can be easily hit, and the necessity of particularly large and expensive gaskets and of doors/portholes having a complex shape because of the concavities.
  • the main object of the present invention is to propose a hinge device, fit to carry out the articulated joint of the door with the body of a related electric household appliance, particularly a washing machine.
  • the hinge device has a two-stage opening system, which defines the smallest encumbrance for the door in correspondence of the opening and closing conditions.
  • Further object is to propose a hinge that guarantees the door opening of around 180 degrees, allowing therefore the maximum accessibility to the load opening of the washing machine.
  • Another object is to propose a hinge device of small dimensions, which guarantees that the door wall is, in the closing condition, on the same plane with the frontal wall of the electric household appliance.
  • numeral 1 indicates a hinge device, particularly for the door 3 of an electric household appliance 2, for instance a washing machine.
  • the device 1 is in a closing position C, in which the wall of the door 3 is practically lined up with the frontal wall 4 of the appliance 2 and closes the load opening 5 of this latter.
  • the device 1 includes a connection element 10, a shaped element 20, a support element 30, stopping means, first 14 and second 34, and friction means 32.
  • connection element 10 is essentially constituted by a flat shaped frontal wall 11, having a series of holes 15. An end 17 of said frontal wall 11 is refolded and supports a first pivot 12. Besides between the refolded end 17 and the frontal wall 11 there is a hollow part 13, slot-type, almost square shaped and having a stop 16 fit to define the maximum opening angle of the hinge 1.
  • the shaped element 20 is constituted by a suitable shaped surface whose ends are refolded toward the inside.
  • the shaped element 20, better shown in figure 9a is constituted by two ends, first 21 and second 23, between which a curvilinear part 20b, a plane part 20a and an end part 20c, almost perpendicular to the plane part 20a, are included.
  • the curvilinear part 20b has almost centrally a tongue 24 carried out in the same wall and protruding therefrom.
  • Said tongue 24 is positioned in correspondence of the first stop means 14 and has a concave housing at his end 26.
  • the first end 21 of the shaped element 20 is hinged to the connection element 10, by means of the first pivot 12, in such a way that the curvilinear part 20b of the shaped element is housed and free to rotate in the slot 13.
  • the support element 30 is rotatably hinged, by means of a second pivot 22, to the second end 23 of the shaped element 20.
  • Said support element 30 is essentially constituted by a fixing plate 31, to which the door 3 is fixed, said fixing plate having a slot 33 fit to be crossed by the second end 23 of the shaped element 20.
  • the second pivot 22 is integral with a refolded end 35 of the support element 30, while the friction means 32 are associated in correspondence of the central part of said second pivot 22, said means 32 essentially constituted by an insert 32a, locked in correspondence of the second end 23 of the shaped element 20.
  • the first stop means 14 are constituted essentially by an elastic plaque 14b, "U" shaped, at the back and almost centrally fixed to the frontal wall 11 of the connection element 10, which supports a sliding roller-type element 14a, rotatably connected to the free end of the elastic plaque 14b.
  • the second stop means 34 are constituted essentially by a stop 36 carried out in the external edge of the slot 33 of the fixing plate 31.
  • connection element 10 is fixed, by means of screws passing through the holes 15, to a side part of the frame 6 of the appliance 2, in correspondence of its opening 5.
  • the operation of the hinge device 1 is very simple and includes the complete opening of the door 3 in two following stages.
  • the hinge device effects a first rotation condition R1 between the shaped element 20 and the connection element 10, moving into the intermediate opening condition B, shown in the figures from 6a to 6c, in which the plane part 20a is almost perpendicular to the frontal wall 11.
  • the roller 14a slides with friction firstly on the external profile of the portion curvilinear 20b and then on the external profile of the tongue 24, which is the prolongation surface for the roller sliding. In this way, there is a friction force of almost constant intensity between the roller 14a and the shaped element 20.
  • the rotation R1 amplitude of the shaped element 20 is therefore delimited from one side by the frontal wall 11 and from the other side by the first stopping means 14.
  • the user acting on the door 3, realizes the second stage of the door opening, so involving the passage from the aforesaid intermediate opening condition B to an extreme opening condition A, shown in the figures 7 and 8, in which the door 3 is opened with an angle of around 180 degrees in comparison with the frontal wall 4 of the appliance 2, so that the door 3 is at the maximum distance from the opening 5.
  • a second rotation condition R2 between the support element 30 and the shaped element 20, is achieved.
  • the fixing plate 31 rotates around the end part 20c by means of the second pivot 22 up to bring the hinge device 1 from the intermediate opening condition B to the extreme opening condition A, shown in the figures from 9a to 9c in which the fixing plate 31 of the support element 30, to which the door 3 is fixed, is almost perpendicular to the plane part 20a.
  • the insert 32a exerts a friction force, of almost constant intensity, on the second pivot 22.
  • the presence of the insert 34 differentiates the values of the counter actions acting against the rotations, first R1 and second R2. More precisely, during the door opening, the friction force between the connection element 10 and the shaped element 20 is smaller than the friction force between the shaped element 20 and the support element 30.
  • the support element 30 firstly rotates around the shaped element 20, realizing the second rotation condition R2, while this latter remains motionless in comparison with the connection element 10, in consequence of the counter action exerted by the housing 26 on the roller 14a, which has bigger intensity than the friction force carried out by the insert 32a.
  • the door 3 reaches the intermediate opening condition B defined by the contact of the stop 36 of the slot 33 with the external profile of the end part 20c.
  • the support element 30 cannot rotate anymore and therefore the force, applied to the door 3 by the user, can release now the roller 14a from the housing 26, causing the first rotation condition R1 of the shaped element 20 around the connection element 10 up to the achievement of the closing condition C of the door 3.
  • the slide element 14a is constituted by a sliding block fit for sliding on the external profile of the shaped element 20. In this way, a friction force of preferred intensity can be achieved, in comparison with the force given_by the friction element 32.
  • a further variant provides that the friction means 32 are interposed also or only between the connection element 10 and the shaped element 20. Positioning an insert 32a also or only in correspondence of the first pivot 12, it is carried out a two-stage hinge device for closing/opening the door 3, in which the realization order of the rotations, first R1 and second R2, can be reversed in comparison with the realization order described in the preferred embodiment.
  • the friction means 32 act therefore as sequencers for the opening and closing phases of the door 3.
  • inserts 32a constituting said friction means 32, are carried out with plastic material or generally with material having such hardness features to achieve successfully the function for which they are designed.
  • the main advantage of the present invention is therefore to provide a hinge device, fit to carry out the articulated joint of the door with the body of a related electric household appliance, particularly a washing machine.
  • the hinge device has an opening system using two phases, which determines the smallest encumbrance for the door in correspondence of the extreme opening and closing condition.
