Definitions

  • the water jets are not directed in a sufficierit variety of directions to strike the dishes from every possible angle so as to perform a thorough cleaning.
  • a dishwasher of the type including an outer water tight housing and a series of dish holding racks, a spray device which essentially includes at least two coaxially and relatively rotatable elements that are provided with means which, by their relative motion, eject one or more movable water jets, issuing concurrently, in several directions and at several heights, said directions being cyclically variable, the inside element con stituting at least a chamber with a supply of water under pressure.
  • the spray device consists of two coaxial cylinders, vertically mounted and rotating at different angular velocities, this including opposite directions of rotation, and located at the center of the dishwasher.
  • Said groove connects the inner cylinder containing the water with the outside cylinder in which there is provided a helical slot of constant or variable pitch so that due to the relative motion of the two cylinders several jet issuing orifices are defined at continually varying heights and radial locations, said orifices constituting those portions of the groove and slot that, at any moment are in common, i.e., superimposed.
  • the dishes to be Washed (radially arranged in the dishwasher housing) are struck by the water jets as the latter are variously oriented and disposed at varying heights.
  • FIG. 1 shows the dishwasher in a vertical sectional view to a reduced scale
  • FIG. 2 shows on a larger scale an elevational view of the spray device only
  • FIG. 3 shows a sectional transverse view taken along the line 33 of FIG. 2;
  • FIG. 4 shows the spray device of FIG. 2 in a longitudinal sectional view, the same being taken along the line 4-4 of FIG. 2;
  • FIG. 5 shows a sectional transverse view taken along the line 55 of FIG. 4.
  • A indicates the dishwasher housing (FIG. 1).
  • B denotes the racks.
  • C is the spray device that issues the water jets in several directions.
  • a vertical shaft 1 constitutes a journal and supports the gears that transmit rotation of a motor 2 to an inner cylindrical element 3 and to an outer cylindrical element 4, both rotating but in opposite directions.
  • the shaft 1 also supports the outer cylindrical element 4 which latter consists of a hollow metal tube provided with a slot 5 connecting the interior to the exterior of the tube, said slot being in the shape of a circular helix of 360 length (FIG. 2).
  • the inner element 3 consists of a hollow cylinder ensheathed by and in rotatable contact with the outer element 4.
  • Said inner element is formed with two external longitudinally extending grooves 6 (passageways) on diametrically opposite sides of its external side surface, the grooves running for substantially the full height of the element 3.
  • the particular object of the pres: ent invention is to allow the distribution of the water under pressure successively at ditferentlocations through the orifices formed by the superimposition of the spiral slot 6 in the outerelement 4 over the grooves 6 in the inner element 3.
  • water under pressure is supplied to the two straight grooves 6 of the inner element 3.
  • the water enters through the annular orifice 7 of a chamber 8 into which it is fed through a pipe 8a.
  • the rotary motion is transmitted to the inner cylindrical element 3 by a pulley 9 keyed on a collar 10 of a sleeve 11 in one piece with the bottom end of the inner cylindrical element 3.
  • an epicyclic gear train consisting, for example, of three planet gears 12 rotatably supported on a disc 13.
  • the planet gears mesh with a pinion 14 which turns with the inner cylindrical element 3.
  • the planet gears also mesh with an internally toothed ring gear 15 that turns with the outer cylindrical element 4.
  • the chamber 8 is water tight with respect to the cylindrical elements 3 and 4, this being accomplished, for example, by sealing rings 16 and 17 received in grooves 18 and 19 formed in collars 20 and 21, respectively.
  • FIG. 1 there is shown in section a bottom casing D consisting of a shroud 22 and a bottom plate 23 through which passes the shaft 1 that supports the collar 10. Said collar is turned by the motor 2 through a belt 24 and pulleys 9 and 25.
  • FIG. 1 it also is possible to see the positions of the racks B constituted by the elements 26 located at different heights and conforming to the outline of the chamber 27 defined by the housing A in the center of which is disposed the spray device C that operates the movable water jets.
  • a spray device comprising:
  • (c) means continually turning the cylinder and tube at different angular velocities so that both the cylinder and the tube turn and experience relative angular motion
