Definitions

  • the present invention relates to revolving sprinkling assemblies for dishwashers, and in particular to a sprinkling assembly capable of moving also with a reciprocating motion in the horizontal plane.
  • the revolving sprinklers of known kind essentially consist in a single revolving device pivoted on a vertical axis central shaft and provided with at least one propulsion nozzle at one end, as well as with other nozzles arranged along said device to sprinkle the dishes contained in the dishwasher rack. Since the rotation axis of said device is fixed, the resulting paths of the nozzles consist in circumferences centered on the rotation axis.
  • the above-mentioned device sprinkles always and only the surfaces of the dishes which are along said circular paths, with a limited washing effectiveness.
  • the area which can be reached by the water ejected from the nozzles approximately corresponds to the area of the square circumscribed about the circular path of the outermost nozzle.
  • the first aspect of the problem has already been dealt with and effectively solved by the applicant through a revolving sprinkling assembly of orbital type.
  • Said orbital sprinkler covers a much greater surface of the dishes thanks to the combination of the motion of a lower revolving sprinkler with that of at least another upper revolving sprinkler mounted in an eccentric position on the lower one, this assembly yet retaining the same overall dimension of a conventional sprinkler.
  • this effective solution does not allow to reach an area greater than the above-mentioned one, i.e. it can be usefully applied only in the case of a dishwasher whose washing space has a substantially square plan.
  • the object of the present invention is to provide a revolving sprinkling assembly which overcomes the above-mentioned limitations of prior art sprinklers.
  • the main advantage of the sprinkling assembly according to the present invention is its capacity of sprinkling also the outermost dishes whenever they are arranged in a rectangular washing space.
  • a further advantage of the present sprinkler is given by the greater surface directly sprinkled by the jets ejected from the nozzles, thanks to the combination of the revolving motion with the reciprocating motion. In this way, in fact, the nozzle paths have a much more complex development.
  • the present sprinkling assembly essentially consists of a vertical feed duct 1, secured to the rear wall of the washing space, at the top of which a support arm 2 is pivoted with a vertical axis and carries at its free end a vertical shaft 3, on which a sprinkler 5 is in turn centrally pivoted.
  • This sprinkler 5 has a reduced size with respect to the width of the upper rack 4 , i.e. of the dishwasher.
  • Said horizontal reciprocating motion is generated by sprinkler 5 itself due to the distance between the axis of shaft 3 on which it is pivoted and the pivot point of support arm 2 on duct 1.
  • the water under pressure passes through duct 1, arm 2 and shaft 3 and reaches sprinkler 5, which revolves due to the effect of at least one propulsion end nozzle 6.
  • the inclined jet of said nozzle 6 generates a reaction force which can be broken up into a first component along the X axis of sprinkler 5 and a second component along a direction perpendicular thereto. While this second component is the one which generates the revolution of sprinkler 5, the component along the X axis is discharged on shaft 3 located on the Y axis of the support arm 2.
  • sprinkler 5 also includes, in its upper portion 9, washing nozzles 7 which however do not give any contribution to the motion since their jets are substantially vertical.
  • the lower portion 10 also includes other propulsion jets 12 oriented as nozzle 6. It should be noted that said nozzles, though defined as propulsion nozzles, also have a washing function, since their jets also have a vertical component.
  • their characteristics define the revolving speed of sprinkler 5 and therefore also the frequency and reciprocating speed of the support arm 2, whereby said characteristics are fixed according to the needs so as to obtain a balanced sprinkling assembly provided with a uniform motion.
  • the illustrated embodiment concerning a sprinkling assembly secured to the rear wall of the washing space for sprinkling the upper rack has a merely exemplificative purpose, in that the same structure can be applied in several other ways.
  • the wall to which duct 1 is secured may be one of the side walls in case the washing space is more long than wide.
  • the reciprocating sprinkling assembly may be located also below the lower rack or above the upper one, by overturning it or not according to the desired position. In these cases, duct 1 can even come out directly from the floor or the ceiling of the washing space, arm 2 being consequently shorter.
  • sprinkler 5 can be of any kind, in particular also an orbital sprinkler as previously mentioned.
