Definitions
- the present invention relates to a washing machine with a tank-body connection sleeve.
- a washing machine usually comprises a body in which is suspended a tub containing a washing drum. Between the opening of the machine and the opening of the tank is mounted a flexible cuff which provides both access to the tank and a liquid-tight separation between the interior of the bodywork and the interior of the tank.
- the suspended tank is subject to oscillations during the operation of the machine and the flexible cuff must be securely fixed to the body and to the tank so that it can follow the tank in its movements and resist any tearing caused by these oscillations.
- edges of the two ends of the flexible cuff are maintained either by clamps mounted around the opening of the machine and the opening of the tank, or by retention grooves formed around these openings into which these edges are forcibly inserted, either by screw and bar fastening systems or rigid frames.
- Document DE-A-3 220 577 gives an example of a flexible cuff, the edges of the two ends of which are held by retention grooves formed around the opening of the machine and the opening of the tank.
- the edges of the end of the cuff connected to the opening of the machine are partly sliding along the sections of the retention groove formed around this opening of the machine parallel to the direction of rotation of the drum.
- the aim of the present invention is to avoid these drawbacks and makes it possible to produce an economical washing machine in which the flexible body-tank connection cuff is securely fixed and ensures good liquid tightness between the interior of the body and the inside the tank, and between the inside of the tank and the outside of the machine, and the positioning of this flexible sleeve is easily mechanizable.
- a washing machine provided between the tank and the body of a connecting cuff whose edges of the two ends are held by grooves or grooves formed around the opening of the machine and the opening of the tank is characterized in that it comprises at least on the one hand in the periphery of the edge of the opening of the machine and / or of the opening of the tank, a groove provided with spaced mortises provided with members self-locking non-return, and on the other hand along the upper and / or lower end of the flexible cuff, a projecting rim intended to be mounted in this groove, and provided in the first place with spaced studs associated with these mortises and each comprising a receiving groove, flexible parallel longitudinal sealing lips in the spaces above and between two consecutive studs.
- the invention is applicable to washing machines provided with a rectangular or circular opening and with a tub with rectangular or circular opening.
- a washing machine 1 schematically illustrated in Figure 1 to 4 comprises a body 2 provided with a top wall of synthetic material 3, a rectangular opening 4 of the machine formed in this wall 3, a pivoting door 5 a plastic tank 6 suspended in the body 2 by springs 7 and provided with a rectangular opening 8, and, a flexible cuff 9 connecting the rectangular opening 4 of the machine and the 'rectangular opening 8 of the tank 6 to separate, in a liquid-tight manner on the one hand the interior of the body 2 and the interior of the tank and on the other hand the exterior of the machine and the inside of the tank 6.
- the tank 6 contains a laundry drum 10 which is rotated by an electric motor 11.
- the flexible cuff 9 in the form of a flexible tube provided with transverse folds comprises an upper end 12 fixed to the edge of the opening 4 of the machine and a lower end 13 attached to the edge of the opening 8 of the tank 6 .
- the washing machine 1 comprises at least on the one hand around the edge of the opening 4 of the machine and / or the opening 8 of the tank 6 of the machine, a groove with smooth walls provided with spaced mortises provided with self-locking non-return member and on the other hand along the upper and / or lower end of the flexible cuff 9 a protruding rim intended to be mounted in this groove, provided in the first place spaced studs associated with the mortises of the groove of the edge of the opening 4 of the machine and / or of the opening 8 of the tank 6 of the machine, and each comprising a groove for receiving this self-locking non-return member of these mortises and secondly, in the spaces above and between two consecutive tenons, of flexible parallel longitudinal sealing lips.
- the washing machine 1 comprises on the one hand in the inner periphery of the lower end of the flexible cuff 9, a skirt 15 intended to cover the inner wall of the edge of the opening 8 of the tank 6 for aesthetic purposes and elimination of any catching with linen introduced into the tank and of any retention of liquid or detergents, and in the inner periphery of the upper end of the flexible cuff 9, a lip d horizontally projecting seal 16 and on the other hand in the inner face of the pivoting door 5 of the machine, a sealing rib 17 framing the opening 4 of the machine and cooperating with this projecting lip 16 of the upper end of the flexible sleeve 9 to seal the liquid between the outside of the machine and the inside of the tank.
- the washing machine 1 comprises in the periphery of the edge of the rectangular opening 4 of the machine, a groove 19 with internal side walls 20 and external 21 smooth, provided with spaced mortises 22 which open through the bottom wall 23 and the external side wall 21 of the groove 19 and which are each provided with a self-locking non-return member constituted by an elastic tongue 24, inclined towards the inside of this groove 19 d 'an angle alpha with respect to the vertical, and forming an integral part of this external lateral wall 21 of the groove 19.
- the flexible cuff 9 comprises in the periphery of its upper end 12, a flexible projecting rim 25 intended to be mounted in the groove 19 of the edge of the opening 4 of the machine.
- This projecting rim 25 comprises along its length spaced tenons 26 associated with the mortises 22 of the groove 19 of the edge of the opening 4 of the machine and intended to retain this protruding rim 25 in this groove 19 and therefore the end upper of the flexible cuff 9, on the edge of this opening 4 of the machine.
- the spaced tenons 26 each comprise on the one hand a body with a cross section substantially in a rectangular trapezoid, having a face 27 cooperating with the elastic tongue 24, inclined in the same direction as that of the inclination of this tongue 24, and according to a angle beta with respect to the vertical, equal to the angle alpha that this tongue 24 makes with the vertical, and on the other hand at its free end a terminal bead 28 which defines with this inclined face 27 a groove 29 for receiving the 'end of this tongue 24 which constitutes the self-locking non-return member of the corresponding mortise.
- the elastic tongue 24 When a tenon 28 of the upper end 12 of the flexible cuff 9 is introduced into a mortise 22, the elastic tongue 24 is displaced, disappears, lets the bead 28 pass and allows its tenon 26 to be put in place. given that the angle beta of the inclined face 27 of the tenon 26 is equal to the angle alpha of the normal inclination of the elastic tongue 24, the tongue 24 follows this inclined face 27 when this tenon is put in place 26. The tongue 24 is then in place on the tenon 26 to hold it in the groove 19. During the oscillations of the suspended tank 6, the cuff 9 is subjected to pulls which tend to pull the tenons 26 out of mortises 22.
- the beads 28 and the grooves 29 hook the free ends of the tongues 24 and cause them to move so that the more the tenons 26 are pulled towards the outside of the mortises, the more these tongues 24 close at utomatically more mortises 22, at the same time increase their pressure on these tenons 26 and prevent them from coming out of these mortises.
- the upper end of the flexible cuff 9 is thus securely attached to the edge of the opening 4 of the machine.
- the flexible projecting rim 25 of the cuff 9 comprises flexible longitudinal sealing lips 31 which conform to the slightest surface irregularities of the groove 9 and thus increase the intimacy of contact between this protruding rim 25 clamped in the groove 19 and the wall of the latter and ensure there a good liquid tightness.
- the pins 26 comprise at their free ends, in their part diametrically opposite to their beads 28 of the longitudinal ribs 33 intended to be hung on the edges of the mortises 22 when the pins 26 are properly positioned in these mortises. These ribs 33 also help to prevent the studs from being easily removed from the mortises 22.
- the tank 6 comprises, around its rectangular opening 8, a groove 36 with an internal side wall 37 and extrene 38 smooth, provided with spaced mortises 39 which open through the bottom wall 40.
- the flexible cuff 9 comprises in the periphery of its lower end 13, a flexible projecting rim 41 intended to be fitted tightly in the groove 36 of the edge of the opening 8 of the tank 6.
- This projecting rim 41 includes tenons along its length spaced 42 associated with the mortises 39 of the groove 36 and intended to retain this protruding rim 41 in this groove and therefore the lower end of the flexible cuff 9 on the edge of the opening 8 of this tank 6.
- the spaced studs 42 each comprise on the one hand a body with a substantially rectangular cross section, and on the other hand at its free end, a peripheral bead projecting laterally 43.
- the beads 43 hang on the edge of the mortises 39 when the tenons 42 are placed in them, and prevent these tenons 42 from being removed from these mortises by simple and weak traction.
- the lower end of the flexible cuff 9 is thus securely attached to the edge of the opening 8 of the tank 6.
- the flexible projecting rim 41 includes flexible longitudinal sealing lips 45 which conform to the slightest surface irregularities of the groove 36 and thus reinforce the contact intimacy between this projecting rim 41 packed in this groove and the wall of the latter and ensure good liquid tightness.
- the washing machine 1 comprises, in the periphery of the edge of the opening 8 of the tank 6 and / or of the opening 4 of the machine, a groove 36 at internal 37 and external 38 smooth side walls, provided with spaced mortises 39 in which, the two spaced parallel vertical notches 46 found in the first example (FIGS.
- each of the mortises 39 in the face outside of the internal wall 37 of the groove 36 are respectively replaced by a vertical notch 48 formed at a first lateral side of each of the mortises 39, in the internal wall 37 of the groove 36, and open in this mortise 39, and by a transverse cutout 49 in this internal wall 37 of the groove 36 at the level of the second lateral side of this mortise 39.
- the cutout 49 and the notch 48 transform the has internal wall 37, at the mortise 39, in an elastic lug 52 which serves as a self-locking non-return member.
- the elastic lug 52 exerts pressure on the corresponding associated tenon 42 of the protruding rim 41 and firmly retains this rim in the groove, 36 by cohesion of this tenon 42 at the level of the protruding peripheral flange 43 of the latter.
- the notch 48 gives a good lateral tightness to the lug 52 and facilitates the mounting of the lug 42 of the cuff 9 in the mortise 39 without compromising the vertical rigidity of this lug 52 which is opposed to an unexpected withdrawal of the latter lug 42.
- the washing machine 1 comprises, in the periphery of the edge of the opening 8 of the tank 6 and / or of the opening 4 of the machine, a groove 36 provided with spaced mortises 39 in which the two spaced parallel vertical notches 46 formed at the lateral sides of each of the mortises 39 in the outer face of the internal wall 37 of the groove 36, found in the first example ( Figures 3 and 4) are respectively replaced on the one hand by two spaced parallel vertical notches 50 open in the mortise 39, formed in the internal wall 37 of the groove 36 at the two lateral sides of this mortise, and on the other hand by a transverse cut 51 in the internal side wall 37 at the central zone of the mortise 39, that situated between these two parallel vertical notches 50.
- the cutout 51 transforms the has internal wall 37 of the groove, at the level of the mortise 39, in two elastic lugs 52, 54 which serve as self-locking non-return member. These lugs exert pressure on the corresponding tenon 42 of the protruding rim 41 and firmly retains this rim in the groove 36 by wedging this tenon 42 at its protruding bead 43.
- the notches 50 give good lateral elasticity to the lugs 53, 54 and facilitate the mounting of the tenon 42 of the cuff 9 in the mortise 39 without reducing the vertical stiffness of these lugs 53, 54 which oppose an unexpected withdrawal of these tenons 42.
