Definitions

  • This invention relates to a driving device for a basket, particularly applicable to dishwashers and is intended to solve in a simple manner a few problems inherent in said applications without resorting to more or less complicated electrical and mechanical devices.
  • the drive is transferred by means of a roller which adheres to an outer rim or another suitable surface formed on said basket.
  • said baskets due to their particular constructional arrangement, are never perfectly circular and thus a certain oscillation of the driving roller is necessary during operation.
  • the rotary basket is nearly always removable and thus mounted on appropriate guideways.
  • the present invention which consists in causing the driving roller to adhere to the basket by utilizing the hydraulic pressure which obtains in the washing circuit or in the feeding main of the dishwasher. By so doing, once the basket has been loaded and introduced, the roller is caused to adhere thereto by virtue of the hydraulic pressure.
  • FIG. 1 shows in particular the device of the invention
  • FIG. 2 is a schematic view of a dishwasher including the device of FIG. 1;
  • FIG. 3 is a detailed view in enlarged scale of the device of FIG. 1 and FIG. 4 is a detailed view on an enlarged scale of a further embodiment of the invention.
  • a dishwasher cabinet diagrammatically denoted at 1, comprises a pump 2, a sprinkler 3 of the type which is driven to rotation by reaction and carries a small sheave 4, with the latter transferring the drive, through a resilient belt 5, to a larger sheave 6 keyed to a mainshaft 7.
  • the mainshaft 7 carries in its bottom end a knurled roller 8 (see also FIG. 3) which adheres to a ring 9 of a resilient material mounted on a rotary basket 10.
  • the lower end of the mainshaft 7 is in the shape of a bush 11 into which a pin 12 is slipped, the latter is a part of a plunger 13.
  • the plunger 13 is slid- United States Patent O" 3,460,550 Patented Aug. 12, 1969 able within a cylinder 14, and the cylinder communicates via a fitting 15 and piping 17 with delivery side 1-6 of the circulation pump 2.
  • the pump has a suction side 18 which opens into a washing chamber or compartment 19.
  • the plunger 13 slides, with a certain clearance, with-in the cylinder 14 which is open at the side away from the fitting 15 since no absolute tightness is required as any possible liquid spillage can be collected in the washing chamber 19. A slight leakage could even be desirable so as to avoid any possible friction or jamming.
  • the top portion (see FIG. 2) of the mainshaft 7 is housed in a coupling 20, which holds a resilient ring 21 to retain a bushing 22 into which the end of the shaft 7 is slipped, so that the shaft can be easily rotated while being allowed slightly to swing in the direction of the arrows 23, with the oscillations being such as to allow for a certain play of the driving roller 8 so as to follow, undisturbed, the displacements of the plunger 13.
  • the delivery side 16 becomes pressurized and the rotary sprinkler 3 rapidly rotates and transfers its rotary drive, properly reduced, from the sheave 4 to the sheave 6 immediately.
  • the pressure of the delivery side 16 acts, with a slight time lag, upon the plunger 13, and the latter causes the mainshaft 7 to be shifted in the direction of the arrow 24 (FIG. 3), so as to approach the driving roller 8 to the resilient ring 9, whereby rotations imparted to the basket 10.
  • FIG. 4 there is disclosed a modification of the invention in which an elastically extensible body is employed in lieu of the plunger 13. More specifically, it will be seen that an elastically extensible body 113 is mounted or guided in a cylindrical casing 114 and a hydraulic connection 115 is provided for the interior of the body 113.
  • the mainshaft 7, knurled roller 8, ring 9,. basket 10, bush 11 and pin 12 are similar to the elements illustrated in FIG. 3.
  • a dishwashing machine having a rotary basket and a drive for the basket, the drive comprising a driving rollers means adherent to the basket, means for exerting hydraulic pressure to obtain adherence of the roller means to the basket, and said hydraulic pressure on the roller means being exerted with a certain time lag with respect to the start of the rotary motion of the roller means.
