Definitions

  • the invention concerns a self-closing of the draining filter access apparatus for a top- loading rotating drum washing machine.
  • the most common of these filtering means consists of a cylindrical box laid out along the axis of the drain pump, which is attached to the base of the machine. This box with the filter, connected to the draining well by piping, is accessible through a quick-remove plug that allows the filter to be removed and cleaned, the said plug being hidden by a gate located, depending on the case, on the front or back of the machine frame.
  • the drain pump is attached to the tub in the extension of a draining well where the protection filter is placed.
  • this assembly requires access through the inside of the drum after placing it in the loading position, so an arm can be penetrated inside.
  • a lifter for the washing drivetrain and the gate mass compensation is then diametrically opposite to the drum access opening, virtually plumb with the basket where the filter is mounted. Therefore, it was deemed practical to arrange the access grid to the strainer under a lifter attachment surface, which is hollowed out and consequently open at its ends.
  • an access apparatus to the machine tub comprised primarily of a body, constituting the base of the lifter, with an opening designed to coincide with an opening of the same shape and dimensions previously made in the cylindrical wall of the drum, which overlaps the filter basket at a determined position of the drum.
  • the opening in the body of the apparatus is normally closed by a lid, thereby reconstituting the normal shape of a lifter, articulated towards one of the sides of the body and including at its end a means of locking by ratchet, which the user can deactivate with one of his fingers.
  • the mass of the assembly corresponds to the normal mass required for this lifter, located opposite the access door to the drum and helping maintain the drum static and dynamic balance. Since the opening made in the apparatus body reduces its mass, the lid must provide the additional mass required to maintain the aforementioned balancing. In addition, the stop when the lid is fully open must be determined so that the said lid remains in this position throughout the entire filter cleaning operation that, thanks to a removable filter basket, can be done outside the machine. This is all the more so in view of its mass, since an untimely fall of the lid would cause the lid to immediately self-lock in the body.
  • the purpose of the present invention is to provide a solution for this disadvantage.
  • This invention resolves the problem involving creating an apparatus that allows, on one hand, the apparatus lid to self-close under its own weight as soon as the drum is brought into the normal load position and, on the other hand, to indicate to the operator, by its vertically, the position of the drum corresponding to the super position of the filter basket by opening the access apparatus body.
  • FIG. 1 shows a front view of the closed apparatus
  • FIG. 3 shows a top view of the closed apparatus
  • - figure 4 shows a front view of the apparatus in an open position
  • - figure 5 shows a below view of the apparatus in an open position
  • FIG. 6 shows a back view of the apparatus in an open position
  • FIG. 7 shows a front longitudinal section view of a drum equipped with the apparatus in an open position
  • figure 8 shows a right side cross section view according to plan P1 of the drum according to figure 7,
  • figure 9 shows a left side perspective section view according to plan P2 of the drum according to figure 7.
  • the figures represent a draining filter access apparatus on a top-loading washing machine, integrated in one of the lifters equipping the washing machine drum 1 , diametrically opposite to the drum 1 access door 2;
  • the said apparatus 10 including a body 11 equipped with an opening 111 normally closed by a lid 12 reproducing the exterior shape of a drum lifter, interlocked to the body 11 by two studs 124 aligned according to an axis XX' inclined towards the back according to an alpha angle of approximately 15° towards the base of the body 11 of the apparatus 10, the lid 12 closing and normally stopping with a ratchet mechanism by its own weight, when the apparatus 10 is located plumb with the access door 2 to the drum, when it is in the loading position.
  • This ratchet is obtained via a flexible locking hook 14, interdependent with the body 11, located at the end of the opening 111 opposite to the articulation of the lid 12, whose beak 141 ratchets on the lower edge of a small window 121, forming a stop catch, made in the wall of a cavity 122 created in the free end of the lid 12 and open on the top to allow the said lid 12 to be released by removing the beak 141 of the flexible hook 14 under the action of a finger, accompanied by an action with the hand intended to bring the lid 12 to the opening stop corresponding more or less to its vertical position.
  • the opening 111 of the body 11 is lined at its base by a collar 112 intended to be fitted into a passageway of a corresponding shape and dimensions made in the drum 1, against the wall of which the apparatus 10 is attached by four screws entering the openings 101 to 104 provided for this purpose in the base of the body 11 as it is the case for the other lifters.
  • the opening 111 of the access apparatus 10 lines up with the sump of the draining well, where a basket containing the filter one wants to clean is placed.
  • figures 1 to 9 one notices: on figures 1 and 3, the access cavity 122 to the beak 141 of the locking hook 14 engaged on the edge of the small window 121, showing on figures 3, 8 and 9 and, on figure 2, the incline of approximately 15° given to the XX' articulation axis of the lid 12, so the lid remains in vertical balancing for a beta angular discrepancy corresponding to the drum 1, in order to facilitate access to the draining well to remove and reinstall the filter basket, as illustrated in figures 7 to 9.

Abstract

L'invention concerne un appareil (10) à fermeture automatique d'accès au filtre de vidange intégré à l'élévateur diamétralement opposé à la porte d'accès (2) du tambour (1), comprenant un corps (11) doté d'une ouverture (111) alignée à une ouverture de forme et dimensions identiques réalisée dans le corps du tambour (1), et un couvercle (12) s'articulant vers le corps (11) et se verrouillant sur le corps (11) grâce à un simple mécanisme à cliquet. L'axe d'articulation du couvercle (12) est incliné vers l'arrière selon un angle alpha correspondant approximativement à l'angle de rotation à conférer au tambour (1) afin de provoquer l'ouverture (111) du corps (11) de l'appareil (10), même lorsque le 'panier' du filtre est placé sur la conduite d'évacuation de la cuve de la machine, afin de fermer automatiquement l'appareil (10) lorsque le tambour (1) retourne en position de chargement.
