Definitions

  • This invention relates to a control linkage for water distribution in domestic washing machines, the linkage being of the type comprising: a lever system which takes its movement from a conventional motor means (such as the programmer) incorporated in the machine and transfers it to a member which directs the water towards predetermined points, and means provided in said lever system for adjusting or presetting the lever system itself.
  • the linkage In order for the water stream to be correctly directed towards the predetermined points, the linkage has to be preset.
  • the linkage comprises two mutually engaged toothed sectors provided at the ends of two levers. The wash requirements can be properly set by adjusting the position of engagement between the two toothed sectors.
  • this known method has the defect of being relatively complicated and bulky, and during the assembly stage requires the assistance of specialists.
  • FR-A-2 446 883 is disclosed a lever system where the adjusting and presetting means act directly on the fixed pivot of one lever.
  • the main object of the present invention is to provide a lever system of the indicated type which incorporates simple and compact adjustment and presetting means without this affecting its operability or its ease of adjustment, and which therefore requires no special experience by the personnel concerned.
  • the adjustment means are provided in correspondence with an articulated joint of the lever system at which two of its elements converge, and comprise an eccentric pin on which one of said elements is pivoted and which is carried by a toothed male member housed in a toothed female seat provided in the other element, so that any variation in the angular position of the toothed male member relative to the female seat, implemented by adjusting the pin, results in an adjustment to the lever system.
  • the female seat is diametrically slotted, so that the male member can be repositioned angularly in the seat without having to be extracted, and by simply rotating it in the seat, this being enabled by the presence of the slot, by the elastic characteristics of the material and by the geometrical shape of the seat.
  • the making of this adjustment causes a slight widening of the female seat followed by the elastic return of the seat into its locking position.
  • control linkage 1 for water distribution in domestic washing machines receives movement from a motor means, not shown but generally consisting of the programmer (timer) incorporated in the machine, and transfers it to amember 2 which directs a water stream towards predetermined points, such as the conventional detergent drawer incorporated in the machine.
  • This linkage comprises a first element or rod 3 of elastically deformable material (such as plastics) which is directly or indirectly connected at its non-visible end to said motor means, whereas at the end visible in Figure 1 it comprises a female seat or eyelet 4 which is diametrically slotted at 5, so that the eyelet is elastically deformable in the sense that its two sides (y) are able to diverge to a certain extent.
  • elastically deformable material such as plastics
  • the inner face (x) of the eyelet is densely toothed.
  • the eyelet 4 houses a male member 6 in the form of a peripherally cylindrical body correspondingly toothed at Z.
  • a discoidal part 7 is rigid with the male member and rests at its edge on a step 8 of the eyelet 4.
  • Thediscoidal part 7 carries an eccentric pin 9 which is lowerly cylindrical at 9A and upperly square at 9B. With the use of a tool, the male member 6 can be rotated by means of the square portion 9B so as to reposition the eccentric pin 9 in the desired direction relative to the eyelet 4.
  • lever 10 is pivoted on a fixed pin provided in the washing machine.
  • the lever 10 terminates with an elongated hole 12 into which a pin 13 of the controlled member 2 penetrates.

Claims (2)

  1. Raccord de commande pour la distribution de l'eau dans des machines à laver électroménagères, raccord comportant: un système de leviers qui emprunte son mouvement à des moyens moteurs conventionnels (tels que le programmateur) incorporés dans la machine et qui le transmet à un élément dirigeant l'eau vers des points prédéterminés, et des moyens prévus dans ledit système de leviers pour ajuster ou prérégler le système de leviers lui-même, caractérisé en ce que les moyens d'ajustement sont prévus en correspondance avec un joint articulé où deux éléments (3,10) du système de leviers convergent, et en ce qu'ils comportent une tige excentrique (9) sur laquelle peut pivoter l'un (10) desdits éléments (3,10) et qui est supportée par un élément mâle denté (6) logé dans un siège femelle denté (4) prévu dans l'autre élément (3), de sorte que toute variation de la position angulaire de l'élément mâle denté (6) par rapport au siège femelle (4), réalisée par ajustement de la tige (9) provoque un ajustement au système de leviers (3,10).
  2. Raccord selon la revendication 1, caractérisé en ce que le siège femelle (4) est constitué par un oeillet présentant une fente (en 5) et prévu dans l'un (10) desdits éléments (3, 10).
