Definitions

  • Machines for washing dishes and utensils of the known type, whether the basket is fixed or movable, are of a somewhat complex construction and, among other things, they do not meet present demands basically because they need a large amount of detergent and washing takes a considerable time.
  • the present invention relates to a machine for washing dishes and utensils and similar articles, of a simpler construction and with more efliciency, in which the volumetric capacity in relation to the total overall dimensions of the machine is raised to a point where for an average load of articles to be washed only one working cycle has to be carried out.
  • the machine according to the invention has the advantage that the basket(s) for holding the articles can be taken out completely and the relative operations of inserting and removing the basket(s) do not entail laborious procedures because the same closing door of the machine provides for the disengagement of the basket(s) when the machine has to be opened and for their automatic centring in the correct position when, on the other hand, the machine has to be closed to start a fresh working cycle.
  • This automatic action is achieved by the present invention by the fact that the basket(s) for holding the articles are disposed on a rotating plate appropriately supported so as to rotate freely and that the means for disengaging the basket(s) from this rotating plate are connected by an articulation with the closing door of the machine in such a manner that the opening of this door shall bring about the raising and hence the disengagement of the basket(s) from the machine, while the closing of the said door effects a lowering and consequently an automatic placing on and in the centre of said rotating plate, the above-mentioned means of placing and disengagement of the basket(s) consisting of strips, on an incline plane, Working bilaterally under the basket and by sliding on some fixed part of the machine.
  • the rotation of the basket(s) together with the abovementioned rotating plate takes place according to the invention by causing jets of water issuing under pressure from one or more ejector nozzles to play on the articles to be washed, from the front and at a certain angle, while Patented Mar. 4, 1969 other jets of water, coming from another ejector nozzle, or other ejector nozzles, differently disposed and angled in relation to the ones mentioned already, play on the same articles from the rear with a braking action, or vice versa so as to wash the articles vigorously on both sides, the angling and disposition of all these ejectors being preselected in such a way as to effect a relatively slow axial rotation of the said basket(s).
  • FIG. 1 represents a machine for washing dishes and utensils in accordance with the invention, provided with two baskets operating independently, in which for the sake of clarity of illustration the lower basket has been removed and the corresponding door opened.
  • FIG. 2 shows the same machine as in FIG. 1 but here the upper door is open and the basket for holding the articles and the relative rotating disc have been drawn in exploded position in solid lines, the working position of the latter having been drawn in broken lines.
  • FIG. 3 is a partial longitudinal section of the upper part of FIG. 1 or lower one of FIG. 2, reproduced with the various members in position detached from one another.
  • FIG. 4 is a longitudinal section of FIG. 2, completed by the baskets the lower of which is shown in the working position and the upper one in the removal position.
  • FIG. 5 is a plan view of FIG. 4 viewed along the transverse plane 5 5
  • FIG. 6 indicates a constructional variant of the machine under consideration in which the baskets are coupled to one another so as to operate jointly on a rotating plate for their common support.
  • FIG. 7 is the machine in FIG. 6 viewed from above on a different scale.
  • the machine comprises a case 1 with two closing doors, an upper door 2 and the other, lower door 3.
  • the supports 4 and 5 are disposed the supports 4 and 5, respectively, on which the rotating discs carrying the baskets 6 and 7, respectively, engaging with the pin 8 and the circular edge 9 of each support by their lower recesses 8a and 9a, are adequately located with free axial rotation.
  • the support 4 is held up by the cross member 10 and the support 5 by the baseplate 11 of the machine, while suitable ball bearingsnot shown-or some other equivalent permit a reduction in the friction involved.
  • the baskets for holding the articles to be washed 12 and 13 are simply inserted in the machine through the doors and automatically arranged on the corresponding rotating discs 6 and 7 as described above, by means of an edge 14 which projects sufficiently from the said discs and is adapted to receive, with an easy fit, a prominence 15 disposed at the bottom of each basket.
  • the ejectors of each pair are slightly out of phase in relation to one another, the sole purpose of this being to direct the washing water as much into the more projecting zone as into the zone of the dishes which is nearer the centre of rotation of the corresponding basket.
  • the present machine in a constructional variant, as is shown in FIG. 6, comprises two baskets 12a and 13a, superposed and adequately linked together simply by fitting in, both being held up by a single support 5a to carry the disc, disposed on the baseplate of the said machine.
  • This constructional solution confers the advantage of a further limitation of the overall dimensions of the machine and also of the manufacturing costs because, by comparison with the previously described machine, this one requires the use of only one rotating disc and only one closing door 2a, besides the installation of a single pair of strips 18a and 19a for guiding and disengaging the baskets.
  • the dishes and the utensils are placed one after the other and parallel to one another so that the jets of water coming from the ejector nozzles 27-28-29 and 30, striking said dishes and said utensils at different angles at first from the front and, after half a turn of the basket from the rear, cause the latter to rotate in one direction or the other according to the inclination which is given to the said ejector nozzles.
  • the dishes and the utensils can be placed in the baskets in other, different positions besides the radial arrangement and the parallel arrangement described above, without thereby changing the washing action which is obtained under the present invention with jets of water for moving and jets of water for braking the rotation of the baskets,
  • Machine for washing dishes, utensils and similar objects characterized by the fact that it comprises at least one supporting disc for at least one basket containing the articles to be washed, rotatably disposed on a coaxial support and a pair of strips for guiding and raising said basket, disposed bilaterally under the latter, connected by means of a hinge with the closing door of the machine and operating, on an inclined plane, against a fixed part of the machine, so as to efiect the raising of the said basket, disengaging it from the above-mentioned rotating disc when the door is opened after the washing operation and, conversely, effecting the lowering thereof, and hence its placing on the rotating disc, when the door has to be closed for putting the machine into action, also that it comprises a series of ejector nozzles emitting water under pressure, disposed on tangential opposition to the baskets, of which ejectors at least one directs the water frontally on to the articles to be washed, previously arranged upright in any way in the baskets,
  • Machine for washing dishes and utensils as claimed in claim 1 characterized by the fact that the rotating disc carrying the basket is engaged coaxially by its support with the interposition of ball bearings, or the like, said support being disposed under the rotating disc so as not to impede the removal and the placing of the basket holding the object for washing on the said disc.
  • Machine for washing dishes and utensils as claimed in claim 1 characterized by the fact that it comprises two or more baskets operating independently, disposed on the same number of discs rotating in the same direction or in opposite directions, and two or more doors located level with said baskets.
  • Machine for washing dishes and utensils as claimed in claim 1 characterized by the fact that it comprises two or more baskets linked coaxially one on the other so as to operate jointly and one rotating disc supporting said baskets, also a single frontal door located level with the said baskets.
