Definitions

  • the present invention relates to a detergent distributor for a laundry washing machine provided with an arrangement for the selective supply of water to each compartment of the detergent distributor.
  • IT-A-1 045 343 there is known a device of this type comprising a piston guided for rectilinear reciprocating movement and actuated by at least one cam of a program unit of the machine through an articulated lever system.
  • the above noted piston is provided with at least one internal throughbore the inlet opening of which is always open towards the water supply conduit of the machine from which it is separated by a per se known air break or the like, while the outlet opening of said bore is selectively communicable with various passages formed in a manifold element disposed above the various compartments of the detergent distributor, each of said passages being associated with one distributor compartment. At each position of the piston, water is thus supplied to a specific single distributor compartment.
  • the lever system is dimensioned such that the piston is always moved to accurately determined operative positions.
  • the detergent distributor is additionally provided with means for adjusting the play existing between the lever system and the piston, said means acting on the lever system in such a manner as to limit the free movement of the levers sufficiently for ensuring an accurately determined stroke of the piston.
  • said adjustment means comprises a support plate connected to one side of the detergent distributor and supporting the fulcrum of one of the levers of the lever system, said one lever acting directly on the above noted piston.
  • an adjustment knob cooperating with the support plate, the actuation of which results in limited displacement of said support plate and thus of the fulcrum of said lever, thus providing for a satisfactory and reliable adjustment of the piston play.
  • a laundry washing machine 4 of the top-loading type comprising a detergent distributor 5 having a plurality of compartments 6, 7, 8 and 9 accessible through respective top openings and adapted to contain the various detergents and/or additives required for carrying out the various washing cycles of the machine.
  • a manual adjustment knob 12 acting on the program unit of the machine for selecting any specific washing program.
  • the top portion of the machine is further provided with a protective cover 13 adapted to be raised to the position shown in Fig. 1 for giving access to the compartments of distributor 5.
  • a removable protective cover 14 having at least one through-opening for accommodating said adjustment knob 12 and/or any other controls that may be required.
  • the detergent distributor under discussion is further provided with a water supply conduit 15 connected in a per se known manner to the water supply mains, and containing a piston 16 guided therein for rectilinear reciprocating movement.
  • Piston 16 is adapted to assume various operative positions in each of which it communicates the water supply conduit with a selected one of the distributor compartments so as to selectively supply water to any one of the compartments.
  • piston 16 is formed to the shape of a fork having a rectilinear slot 17 for the engagement of a pin 18 formed integrally with a lever 19.
  • Lever 19 comprises two rectilinear portions 20 and 21 connected to one another by an arcuate portion 22, and is pivotally mounted on the frame 23 of the machine with its rectilinear portion 21.
  • the fulcrum of lever 19 is formed by a rotatable shaft 24 excentrically connected to lever 19 and mounted on the frame of the machine. At its top, shaft 24 is provided with at least one recess 25 accessible through a corresponding opening formed in the frame of the machine for rotating the shaft within a limited range by means of a suitable tool.
  • a slot 26 for the engagement of a pin 27 projecting from the free end of a further lever 28 disposed in a position below first lever 19.
  • Second lever 28 is pivotally mounted on frame 23 in proximity of the articulated connection between first lever 19 and piston 16, and is formed with a laterally projecting cam follower 29 cooperating with the peripheral profile of a control cam 30 fixedly mounted on a shaft 31 of the program unit 32 of the machine.
  • the described lever system is additionally provided with per se known resilient means (not shown) adapted to bias cam follower 29 into engagement with cam 30.
  • This system for actuating the piston in- avoidably involves some play between the various elements, whereby the stroke of the piston tends to become inaccurate, resulting in devia- 'tions from its correct operative positions.
  • the invention provides adjustment means constituted by the above described rotatable shaft 24.
  • Adjustment of the piston play is effected by rotating shaft 24 over a limited range by means of a suitable tool inserted into recess 25 thereof, whereby the fulcrum point of lever 19 is displaced due to the excentric connection between lever 19 and shaft 24.
  • cover 14 has exclusively aesthetic and protective functions and may be attached and detached by employing a snap mounting without the aid of any tools.
  • the described play adjustment means is of compact and simple construction and simple operation. It may be installed at any suitable position even in laundry washing machines of the front loading type without thereby exceeding the scope of the present invention.
