Definitions

  • the present invention relates to a washing machine with a tub made of synthetic material.
  • a washing machine usually comprises a tub which receives a laundry drum and supports systems for emptying the tub and for driving this drum in rotation.
  • the tank is often suspended from the washing machine body by one or more tension springs and / or elastic shock-absorbing feet.
  • tension springs frequently include ends bent in hooks or in open attachment loops, intended to be hung in suspension holes formed in the tank and in the bodywork, where these hooks can pivot freely.
  • the free space which separates the tank from the body is often small, which does not facilitate the installation of these springs in the body during a suspension of the tank, when these springs are present. in any position. Indeed, it is first necessary to put them respectively in the mounting position and then hang them in the corresponding holes in the body.
  • the aim of the present invention is to avoid these drawbacks and makes it possible to produce a washing machine with a tub of synthetic material, suspended in a bodywork, by one or more tension springs with ends curved in hooks or in open fastening loops, assembly is easily and quickly carried out both manually and mechanically.
  • the washing machine with plastic tub suspended in a bodywork by one or more tension springs whose ends are bent in hooks or open attachment loops is characterized in that the tub comprises suspension ears respectively provided with cells which fulfill two functions in the positioning of the tank in the bodywork: a function of holding the suspension springs in the mounting position and a function of suspending the tank, with freedom of oscillation, with the ends bent in hooks or open loops for attaching these springs.
  • a washing machine 1 produced according to the invention, partially and schematically illustrated in FIG. 1, comprises a body 2 whose front wall and top wall are removed and are not shown, and a tank 3 made of synthetic material intended for be introduced into the bodywork 2 and suspended therein by means of four tension springs, two front suspension springs 4 and two rear suspension springs 5.
  • the tension springs 4 and 5 have ends bent in hooks or in open attachment loops 6.
  • the curved lower ends of the front suspension springs 4 are hooked in cells 7 of the front suspension ears 8 of the tank 3, and the curved upper ends of these front springs 4 are engaged in holes 9 protruding front tabs 10 of the bodywork 2.
  • the curved lower ends of the rear suspension springs 5 are hooked in cells 11 of the rear suspension lugs 12 of the tank 3 and the curved upper ends of these rear springs are mounted in holes 13 of the rear lateral tabs 14 of the bodywork 2.
  • the front 8 and rear 12 suspension lugs are formed either on the body of the tank 3 or on the edges of a cover 15 of this tank 3.
  • the tank 3 comprises suspension lugs 8 and 12 respectively provided with cells 7, 11 which fulfill, in an installation of the tank 3 in the bodywork 2, two functions: a function for holding the suspension springs 4 and 5 in the ready-to-assemble position and a function for suspending the tank 3 with freedom of oscillation, at the ends bent in hooks or in open attachment loops 6 of these suspension springs 4 and 5.
  • the suspension springs 4 and 5 have ends bent in hooks 6 in an identical manner, and the suspension lugs 8 and 12 of the tank comprise cells 7 and 11 having an equally identical structure for receiving these identical ends of these springs.
  • these cells 7 and 11 have orientations which are determined respectively by those of these springs at the time of their mounting in the bodywork 2 during a suspension of the tank 3.
  • the suspension springs 5 must be vertically arranged and the cells 11 of the suspension lugs 12 then have a vertical orientation while the suspension springs 4 must have a predetermined inclined position with respect to the vertical (FIG. 1) cells 7 of the suspension lugs 8 then have an orientation also inclined in the same direction as that of these springs with respect to the vertical.
  • FIGS. 2 to 4 one end of a suspension spring 5 and one suspension lug 12 of the tank 3 made of synthetic material intended to receive this end of this suspension spring 5 are schematically illustrated in FIGS. 2 to 4 and described only below.
  • the end of the suspension spring 5 is bent into a flat hook 6, the two branches of unequal length, a short branch with free end 16 and a long branch 17 attached to the spring, are located in the same plane and are interconnected by a curved part or elbow 18.
  • the suspension lug 12 of the tank 3 is constituted by a tongue with substantially parallel faces 20, 21 on which is formed a cell 11.
  • the cell 11 comprises in its upper part a suspension hole 22 having a dimension greater than the cross section of the branches 16, 17 and elbow 18 of the hook 6 of the spring 5, and formed transversely in this ear, and in its lower part on the one hand a slot of support 23 having a dimension at least equal to or slightly greater than the cross section of the arms 16, 17 and elbow 18 of the hook 6 of the spring 5, extending the hole 22 downwards radially, and forming with this hole a p assage of a height at least equal to the height of the short bra nche with free end 16 of the hook 6 of the spring 5, and on the other hand a retaining appendage 24 perpendicular to the suspension lug, laterally extending the slot of holding 23 and its walls respectively by a groove open upwards 25 and by walls 27, 28, 29 of this groove, and an elastic clamping pin 30 formed, on one 27 of the side walls of this appendage 24 and projecting in the open groove 25 thereof, and provided with a retaining boss 31.
  • the suspension springs 4 and 5 are mounted by their lower ends on the tank 3, then the whole "tank 3 and springs 4, 5 "is introduced from the top of the washing machine into the bodywork 2, through the space occupied by the upper wall of this washing machine 1, until the upper ends of the suspension springs 4 and 5 are at the holes 9 and 13 of the tongues 10 and 14 of the body 2 in which these ends are to be hooked, then the hooks constituting the upper ends of these springs 4 and 5 are engaged in these holes 9 and 13, and finally the tank 3 is released and under the effect of its weight which is greater than the clamping force of the lugs 30 of the cells 7 and 11 on the hooks 6 of these suspension springs, the hooks 6 are released from these lugs tightening 30, leave the grooves 25 of the appendix 24 and the f entes 23 and enter the suspension holes 22 where the curved or bent parts 18 of these hooks shown in broken lines in Figure 4 are stopped by the
  • the lower ends of the springs 4 and 5 are placed in the cells 7 and 11 of the suspension lugs 8 and 12 of the tank 3 which simply consists in sliding the hooks 6 of these springs 4 and 5 in the cells 11 through the holes 22-slots 23 and grooves 25 until they are blocked by the clamping lugs elastic 30, can also be executed mechanically and simultaneously.
  • This advantage makes it possible to further reduce the time for setting up the tank 3 in the bodywork 2.
  • the appendages 24 formed on one of their faces are extended through the slots 23 on their other face 21 by complementary appendages 33 which are provided with a groove open at the end and at the top 34.
  • complementary appendages 33 increase in these cells 11 by the walls of their grooves 34, the surfaces for immobilizing or holding the hooks 6 of the springs 4 and 5 engaged in these cells.
  • the simple elastic clamping pin 30 is replaced by two elastic clamping pins 35, 36 symmetrical to the axis of the open groove 25 of the appendix 24 of this cell 11.
  • These symmetrical clamping lugs reinforce the retention of the hooks 6 of the springs 4 and 5 in the cells 7 and 11 of the suspension lugs 8, 12 of the tank 3.
  • a notch 38 is preferably formed in the part of the walls of the open groove 25 which separates these two symmetrical clamping lugs 35, 36 to increase the elasticity of these lugs.
  • the walls of the ears 12 and those 27, 28 of the grooves 25 can be hollowed out in a known manner to facilitate molding and in particular the cooling of the blades of the mold making the grooves 25. These recesses must not hinder or prevent setting in place. places suspension springs 4 and 5.
