Definitions

  • the present invention refers to a dishwasher with rack adjustable in height.
  • dishwashers in particular for household use, that have inside of a tank a rack that is extractable and selectively adjustable in height in order to support dishes having various sizes
  • a dishwasher of such type is known for instance from DE-A-4228954 in which a dishwasher rack is laterally provided with elastically biased levers, each one of which exhibits three grooves at different heights in which a tang belonging to a triangular plate sliding along a guide predisposed for the horizontal sliding of the rack is selectively engageable.
  • the adjustment of the height of the rack is carried out by horizontal pressure on the fore ends of the levers so as to take the tangs out of the grooves in which they are inserted, followed by lifting or lowering of the rack up to the desired position and by the insertion of the tangs into a new groove by release of the levers
  • the height adjustment of the rack is carried out by operating separately on each lever.
  • EP 0 848 930 discloses a dishwasher with height adjustable rack according to the preamble of claim 1.
  • scope of the present invention is to present a dishwasher with a device for the height adjustment of the rack that is simpler in use as compared to the known devices.
  • a dishwasher 1 provided with a washing tank 2 that houses at least one rack 3 extractable from the tank 2 and suitable to support the dishes to be washed.
  • the rack 3 is preferably made of plasticized metal rod and it is sliding horizontally along lateral guides 4 having substantially C-shape that are slidingly mounted on rollers 5 hinged on respective side walls of the tank 2.
  • the rack 3 is connected with guides 4 by means of rollers 101, 102 that engage inside the same guides.
  • Said rollers are connected with a flange 6 that is part of a device 7 that allows the lifting of the rack 3. Two devices 7 for the lifting of rack 3 are provided but only one device 7 will be described hereinafter.
  • Said device 7 comprises also a pair of walls 8 that are fixedly mounted to the rack 3 and sliding along appropriate guides 9 of the flange 6.
  • Said walls 8 are each provided with central projections 10 on the surface facing the flange 6 and with an elastic hook 11 that is placed on the bottom and better shown in Figure 7.
  • housings 12 are provided in which rollers 13 are revolvingly hinged that are placed each one in correspondence of each wall 8.
  • Said rollers 13 are each provided with a pair of L-shaped projections 14 that can act as a guide for the central projection 10 of each wall 8.
  • the rollers 13 are provided with teeth 15 on the lower surface that can singularly couple to an appropriate cavity 16 that is provided in the housings 12 of the flange 6 in such a way so as to allow the locking of the respective rollers 13 or the single counter-clockwise rotary movement by external operation, as better visible in Figures 5 and 6.
  • the housings 12 are provided with round guides 70 for the rollers 13 and with holes 71 in which the pins 72 of the rollers 13 are inserted.
  • the cavity 16 is made into an elastic tang 80 belonging to the same housing 12.
  • the device 7 allows the height adjustment of the rack 3 between an upper position and a lower position shown respectively in figures 3 and 1.
  • the upper edges of the walls 8 rest on the upper edge of the flange 6, the central projection 10 of the walls 8 is inserted between the pair of L-shaped projections 14 of each roller 13.
  • the dishwasher previously described can be subject to several modifications within the sphere of the present invention.
  • the walls 8 of the lifting device 7 can be provided with two central guides 10 and two elastic hooks 11 so as to allow the adjustment of the rack 3 in more than two different vertical positions.
