Definitions

  • the present invention concerns a dishwashing machine provided with a device for the division of the water flow between the upper and lower sprinkler, consisting in a nozzle of variable flow rate preferably achieved by the relative motion of two members of said nozzle so as to change the water flow cross-section.
  • the object of the present invention is to provide a dishwashing machine capable of carrying out the above-mentioned division of the flow by means of a variable section nozzle, wherein the adjustment of the flow is preferably carried out by means of the relative motion of two members of said nozzle so as to change the water flow cross-section.
  • the change of the flow rate of one nozzle involves an opposite change in the flow rate of the other nozzle, whereby it is possible to differentiate the flow and pressure of the water reaching the upper sprinkler and the lower one by acting on one nozzle only.
  • the dishwashing machine has the advantage that it is possible to direct a water stream of greater intensity towards the most soiled dishes, or a stream of lower intensity towards the less soiled ones or those requiring a less vigorous washing because they are more fragile and/or more delicate.
  • variable flow nozzle 1 on the roof of the washing space to feed the upper sprinkler 3; this position facilitates its adjustment by the user, but the same nozzle 1 could be alternatively positioned on the base of the space to feed the lower sprinkler 4.
  • the constant capacity pump 5 supplies the water feeding the upper sprinkler 3 and the lower one 4; the change in the cross-section of nozzle 1 causes a change in the feed flow to sprinkler 3 proportional to said cross-section change, and consequently an opposite change in the flow to sprinkler 4, not considering the flow resistance in the upper supply duct 6.
  • the use of the dishwashing machine is more flexible since, for example, it is possible to put the dishes soiled some hours before in the upper rack and those just soiled in the lower rack, and then increase the cross-section of nozzle 1 to make a stronger washing of the dishes on which dirt had time to stick more firmly, and this without any need to extend the washing cycle with greater water, power and detergent consumption.
  • variable section nozzle wherein a fixed nozzle 7, mounted at the outlet of the upper supply duct 6 in fig.1, is integral with a central body 8 connected thereto through one or more radial fins extending between said body 8 and nozzle 7; an adjustment nut 9 is mounted on said nozzle 7 so as to shift axially with respect thereto, for example by means of a threading, and is internally shaped so that the area of the flow cross-section included between said nut 9 and body 8 changes between a maximum value with the nut completely forward (fig.2) and a minimum value with the nut completely back (fig.3).
  • this minimum value could be nothing, as a limit, so as to direct the whole flow from the pump to the other sprinkler.
  • the coupling between nozzle 7 and nut 9 also includes a end stop for the limitation of the maximum flow rate, which depends, however, on the pump supply capacity.
  • connecting fins between body 8 and nozzle 7 are useful also for straightening the water flow so that it is less turbulent and therefore the least possible dispersion is achieved in the passage between nozzle 1 and collector 2 of the upper sprinkler 3 (fig.1).
