Definitions

  • the present invention refers to a lifting device for the lower rack of a dishwasher.
  • Known dishwashers usually comprise two racks, an upper one and a lower one, for containing dishes and pans to be washed.
  • loading of the lower rack obliges the operator to continuous and sudden bending movements in order to take the dishes and the pans from the kitchen top and to position them between the grids of such rack, that is located at an extremely low position.
  • a solution to this problem consists in the realisation of a lifting device for the lower rack of the dishwasher that allows to bring it to a height equal to that of the upper rack.
  • the most recent known art exhibits a lifting device in which a lower rack of a dishwasher is placed on a base that is connected with the upper ends of two crossed levers that are hinged so to be able to slide on appropriate guides of the base.
  • the lower ends of the crossed levers are hinged on respective pistons that are capable to slide in two or more hydraulic cylinders that are positioned on the dishwasher door.
  • a hydraulic or pneumatic compressor feeds a fluid to a valve that distributes it through hydraulic circuits to two or more hydraulic cylinders. The latter, that are necessary to balance the rack on two sides, simultaneously transmit opposite movements to the crossed levers and thus cause lifting of the rack.
  • the aforesaid lifting device involves an increase in the thickness of the door of the dishwasher and an increase in the weight of the same.
  • object of the present invention is to realise a lifting device for the lower rack of a dishwasher that has a simpler structure and does not make the closing door of the dishwasher heavy, while assuring at the same time its water tightness.
  • a lifting device for the lower rack of a dishwasher comprising a washing tub with a bottom wall, a back wall and a front face provided with a closing door, characterized in that it comprises two pairs of crossed levers that are hinged to each other at a center line, said levers having upper ends for the support of the lower rack and lower ends that are controlled to be drawn near and apart from each other by at least one telescopic shaft that is carried by the lower rack and extends horizontally along the bottom wall of the washing tub and that is controlled by motor means that are positioned in proximity of the back wall of the tub.
  • FIGS 1 and 2 there is shown a lower rack 20 provided with a lifting device 1 according to the invention, that is placed above the closing door 30 of the dishwasher in open position.
  • the lower rack 20 is connected at the sides with two pairs of rectilinear levers 6-7 whose upper ends are turningly hinged in 9-10 on coupling boxes 11-12 that are capable to slide along bushes 13-14 that are fixed on a longitudinal bar 24 belonging to the lower rack 20 of the dishwasher.
  • the two pairs of rectilinear levers 6-7 cross at a center line in a fulcrum point 8 and they extend in height.
  • the lower ends of the levers 6-7 are in turn provided with wheels 25-26 that are capable to slide on horizontal guides 80, in proximity of the sides of the closing door 30 of the dishwasher, as shown in Figure 6.
  • the aforesaid lower ends of the levers 6-7 are in addition hinged in 18-19 on respective supports 16-17, internally threaded, that are controlled to be drawn horizontally near and apart from each other along the sides of the closing door 30 by means of their screw engagement with tubular parts 51-52, that are externally threaded.
  • These latter tubular parts 51-52 are identical but with threads opposite to each other and they are fixed to respective ends of a tubular part 53.
  • the tubular parts 51-52 and the tubular part 53 are made up of two identical pieces that are symmetrically mounted on and fixed to each other by means of flange connection 200.
  • Said tubular part 53 is the most external terminal part of a telescopic shaft 40 that extends along the bottom 50 of the washing tub 70 of the dishwasher and that is also made up of an intermediate tubular part 3, that is capable to slide inside the tubular part 53 and that is connected with it for the rotation by means of a coupling key 9 that is positioned at a first end, and by an internal rod 4 that is coaxial to the internal tubular part 3 and connected with it by means of a coupling key 91.
  • An external spring 33 is interposed between the second end of the intermediate tubular part 3 and a round projection 48 of the rod 4.
  • An internal spring 32 is in turn interposed between the external end of the tubular part 53 and the internal end of the rod 4.
  • the rod 4 terminates with a conic part 41 that is inserted in a corresponding cavity of a conic body 43 that is fixed to the back wall 44 of the washing tub 70 of the dishwasher.
  • a conic part 41 that is inserted in a corresponding cavity of a conic body 43 that is fixed to the back wall 44 of the washing tub 70 of the dishwasher.
  • one of the two telescopic shafts 40 that make up the lifting device 1, that is symmetrical in all the rest to a longitudinal median plane, is connected through the conic body 43 to an electric driving motor 42 that is in turn fixed to the back wall 44.
  • the rotation motion of the telescopic shaft 40 connected with the electric motor is transmitted to the other telescopic shaft 40 by means of a pair of pinions 2 that are engaged with respective worm screws 5 that are fixed to the ends of a propeller shaft not visible in the figures, that extends transversally of the washing tub 70.
  • the mutual slide of the tubular parts 53 and 3 and of the rod 4 and the extension of the springs 32 and 33 facilitates the extraction of the lower rack 20 from the washing tub of the dishwasher.
  • the rack 20 by means of the wheels 25-26, slides on the open door 30 of the dishwasher up to a position in which a round extension 22 of the tubular part 53 of a telescopic shaft 40 gets in abutment with a lock 29 of the door 30 of the dishwasher ( Figure 1).
  • the telescopic shafts 40 are in the position of maximum extension that is possible for them, with the tubular part 3 almost completely out of the tubular part 53 and the rod 4 also almost completely out of the tubular part 53 and of the tubular part 3 ( Figures 3-5).
  • a contact sensor 23 placed on the lock 29 of the door 30 gives then the consent or even automatically starts the electric motor 42 that provides to the rotation of the rod 4 connected with it.
  • the rotary motion is transmitted by the rod 4 through the key 91 to the tubular intermediate part 3 and from the latter to the external tubular part 53 by means of the key 9.
  • the transmission device made up of the pinions 2 and of the pair of screws without end 5 provides to the rotation of the other telescopic shaft 40.
  • the rotation of the tubular parts 53 allows the rotation of the parts 51, 52 that are fixedly mounted to it and, owing to the threaded engagement of the latter with the supports 16 and 17, the consequent movement of mutual approach of the supports 16-17 and likewise consequent greater inclination upward of the levers 6-7.
  • the upper ends of the levers 6-7 therefore get near to each other by sliding with their coupling boxes 11-12 along the respective bushes 13-14 and they move upward thus causing as a consequence the lifting of the rack 20, shown in Figure 2.
  • the maximum lifting that is fixed by an appropriate lock not shown in the drawings, corresponds to the positioning of the lower rack 20 at a height substantially equivalent to the height of an upper rack of the dishwasher so that the loading of dishes and of pans to be washed becomes easier.
  • the rack 20 gets pushed inside the washing tub of the dishwasher with consequent shortening of the telescopic shafts 40 and compression of the springs 32 and 33.
  • the load of pans and dishes in the rack 20 exceeds the load of the springs 32 and 33 in order to maintain the rack 20 inside the dishwasher.
  • a variation of the movement system of the telescopic shaft 40 connected with the electric driving motor 42 provides a connection of the telescopic shaft 40 to said electric motor by means of a flexible wire with appropriate connector, that can be partially extracted during the stage of the rack extraction.
