Definitions

  • the invention relates to a water delivery nozzle for domestic washing machines (for laundry or dishes), provided with a programmer (timer) comprising a nozzle which is angularly mobile under the control of the timer, is connectable to a water supply, and can be directed towards one of a series of utilization inlets.
  • German utility model 66 07188 describes a device of this kind.
  • the utilization inlets pertain to the various compartments of the container into which the washing machine user places the various substances (detergents, bleaches, softeners, etc.) which are used during the washing machine operating cycle.
  • the water directed towards a given compartment removes the relative substance and transfers it into the machine tub.
  • machining inaccuracies due to the fact that the components of the device are constructed of moulded and/or blown thermoplastic material
  • assembly inaccuracies and wear lead to errors in the aiming of the nozzle which, even if modest, at least lead to inadequate water feed to the compartment, and thus incomplete removal of the contained substance. If the aiming error is greater, it is possible for the water not even to reach the compartment.
  • the main object of the present invention is to provide a device of the aforesaid type, which allows exact directioning of the nozzle independently of assembly and/or machining errors or wear of the moving parts.
  • a device of the aforesaid type characterized essentially in that the nozzle is traversed by an elbow channel, is mobile along its axis of rotation, and is provided with engagement means arranged to engage with fixed counter-means when the nozzle moves along said axis under the thrust of the water.
  • the reference numeral 1 indicates a stationary conduit which is connected in known manner to a water supply, for example to the water main, by way of a solenoid valve, not shown, controlled by the programmer (timer) provided in the washing machine in which the device according to the invention is mounted.
  • a nozzle 3 On the end of the conduit 1 there is mounted a nozzle 3 in such a manner that it can rotate about the axis of said conduit and move axially along said axis.
  • the nozzle is traversed by an elbow channel 5 which tapers at its free end, at 6, and which at its other end has a cross-section which corresponds to that of the conduit 1 (to enable it to be mounted thereon, rotated and slid), and is bounded by an annular shoulder 4 which by abutting against the upper contour of the conduit 1 limits the axial movement of the nozzle.
  • the nozzle upperly comprises a support ring 7, a pin 8 surrounded by said ring, and a tooth 9 of substantially triangular or trapezoidal cross-section (see Figure 3).
  • the pin 8 traverses a corresponding bore 10 provided in a stationary wall 11 which defines the compartment, not shown, which houses a normal extractable drawer into which the user places the wash substances.
  • the reduced end part 12 of the pin 8 is of square or polygonal section, and on it there is mounted the end of a lever 13 having a correspondingly configured hole 14, so that the part 12 can slide along said hole 14 but at the same time be torsionally coupled thereto.
  • the lever 13 traverses a guide slot 15 provided in the wall 11, and is hinged at 16 to one end of a rod 17, the other end of which is hinged at 18 to a lever 19.
  • the lever 19 is hinged at 20 to a fixed point, and is loaded by a spring 21, the purpose of which is to keep it in contact with a cam 22 mounted on an output shaft 23 of the conventional programmer (timer) 2.
  • the levers 13 and 19 and the rod 17 constitute an articulared parallelogram.
  • said wall 11 at predetermined angular distances from each other and directed along the radii of a circle having its centre coinciding with the axis of the conduit 1, there are provided grooves or notches 24 in positions corresponding with the projection 9, and having substantially the same configuration as this latter.
  • the conduits 25 lead for example to the compartments of a normal container for receiving the wash substances which the inlet water provided by the nozzle 3 discharges into the washing machine tub.
  • the invention also covers a design in which a set of teeth replaces the grooves 24, and a groove replaced the tooth on the nozzle.
