Definitions

  • the present invention relates to dishwashers, and in particular to a dishwasher with an improved drying system and a relevant operating cycle.
  • the operating cycle of a dishwasher usually includes a final drying step intended to make the dishes ready for use as soon as they are extracted from the dishwasher, and to this purpose the dishwasher is provided with a drying system that can be made in various more or less sophisticated ways.
  • the most advanced systems include members outside the wash tank, such as devices for capturing, condensing or discharging vapor, with possible heating of the air reintroduced into the tank.
  • the object of the present invention is to provide a dishwasher which overcomes the above-mentioned drawbacks.
  • the main advantage of the drying system of the present dishwasher is that of acting directly on the dishes, in particular those located in the bottom rack, by generating an air stream that "spreads" the water drops present on the dishes favoring their evaporation.
  • a second advantage stemming from this air stream is the creation of convective motions that take the vapor contained in the air more into contact with the tank walls favoring its condensation, since the tank walls provide a heat exchange greater than the dishes.
  • Still a further advantage of the present dishwasher stems from the fact that the auxiliary members of the drying system are few, simple and inexpensive, so as to improve the drying performance with a minimum increase in cost and without negatively affecting reliability.
  • a dishwasher according to the present invention conventionally includes a pair of revolving sprinklers S, S' respectively arranged on the bottom B of the wash tank and under the top rack R (the bottom rack is not shown).
  • the novel members arranged above the tank bottom B include a mobile arm A carrying a drive gear G suitable to engage a toothed wheel T integral with the bottom sprinkler S, which is provided with a pair of blade-shaped profiles P arranged along opposite sides of its two arms.
  • sprinkler S When arm A is in the rest position illustrated in Fig. 2 , and therefore gear G does not engage the toothed wheel T, sprinkler S operates in the conventional way revolving under the effect of the reaction to the water jets ejected through nozzles N, since it is mounted idle on the tube connecting it to the wash pump.
  • the other novel members of the drying system secured under the tank bottom B include a mounting support essentially consisting of a plate H with a cylinder J perpendicular thereto and whose top projects through the tank bottom B. Under plate H there are secured a mechanism for moving arm A, that will be better described further on, and an electric motor M whose drive shaft D projects at the top of the support through said cylinder J and carries an end gear E.
  • arm A rotates with respect to the mounting support thanks to a vertical cylindrical portion slidably inserted in cylinder J, i.e. arm A has a vertical cross-section that is substantially L-shaped.
  • Adequate sealing means such as O-rings or the like, are obviously located between arm A and cylinder J, as well as at the point where shaft D enters arm A.
  • the bottom sprinkler S acts in practice as the rotor of a fan generating a vertical air stream that significantly improves the drying performance of the dishwasher, as explained in the introductory portion.
  • gear G is disengaged from the toothed wheel T by returning arm A to the rest position, whereby sprinkler S is again free to revolve idle on its vertical axis.
  • the period of activation of the auxiliary members of the drying system must not necessarily coincide with the duration of the drying step, and it is also possible to provide more than one period of activation during said step.
  • FIG. 6 A possible mechanism for moving arm A between the rest position and the work position is illustrated in figures 6 and 7 , where there is seen a linear actuator X fixed under plate H, with the stem Y of said actuator X connected to a screw Z screwed into the vertical cylinder of arm A through a slot L formed in cylinder J. On the same screw Z there is also secured a first end of a return spring C whose second end is fixed under plate H.
  • actuator X when actuator X is powered its stem Y is extended and screw Z rotates arm A to the work position, whereby motor M can rotate sprinkler S, whereas when actuator X is switched off the return spring C causes the rotation of arm A to the rest position, disengaging the drive gear G, and the retraction of stem Y.
  • auxiliary members of the drying system could be changed according to specific manufacturing needs, e.g. by using a different type of actuator to move arm A or a different kinematic chain to connect motor M to sprinkler S (e.g. two pulleys and a belt).
  • sprinkler S could have members suitable to generate an air stream that are different from the above-illustrated profiles P and possibly integrated in the sprinkler itself, that could be shaped like a fan rotor.
