Definitions

  • the present invention relates to dishwashing machines, and in particular to a dishwasher provided with a device which allows the user to adjust the drying cycle.
  • the mixing with ambient air is necessary in order to reduce the humidity percentage of the air coming from the tank, so as to prevent the formation of condensate on the discharge outlet or on the adjacent areas.
  • the moist air taken out of the tank is replaced by dry ambient air, until a complete drying of the dishes in the tank is achieved.
  • the mixing is carried out with progressively decreasing proportions.
  • a lot of dry air is required to reduce the humidity percentage of the air taken from the tank, while as the cycle goes on said air is less and less moist and therefore the amount of dry air to be mixed therewith also decreases.
  • This automatic adjustment is performed by electromechanical mechanisms which progressively reduce the intake cross-section of the dry air and/or of the moist air.
  • the user has only an indirect control over the drying cycle, in that he can set a washing cycle with a temperature of the final rinsing which is more or less high. If the user selects a "saving" program with a temperature lower than usual this implies extending the drying time, since the amount of water at saturation contained in the air is obviously proportional to its temperature. As a consequence, in order to remove the same amount of humidity from the tank it is necessary to take out a greater volume of air and thus keep the fan running for a longer time.
  • the user can not select the intensity and/or duration of the drying cycle according to the need, i.e. he must stick to the average drying cycle set at the factory on the basis of standard tests.
  • the object of the present invention is to provide a dishwasher which overcomes the above-mentioned drawbacks:
  • the fundamental advantage of the dishwasher according to the invention is exactly the freedom of choice given to the user, who can decide to use a drying cycle which is more or less long and/or strong independently of the selected washing cycle.
  • a further advantage of this dishwasher comes from the structural simplicity of the above-mentioned devices which positively affects the ease of use and the manufacturing costs.
  • the dishwasher according to the invention includes a conventional centrifugal fan 1 which takes the moist air out of the tank (flow A) through a duct 2 and mixes it with dry air (flow C) coming from the space below the tank before discharging it through an outlet 3.
  • the intake of dry air takes place through an opening 4 arranged on the side of the fan motor 5, i.e. on the side opposite with respect to duct 2, and the mixing occurs within the fan itself.
  • the moist air removed from the tank is replaced by dry air coming from outside (flow B) through an opening opposite the removal opening.
  • the novel aspect of the present invention is a chokable grid arranged at the mouth 6 of the removal duct 2.
  • An example of such a grid is illustrated in detail in figures 2 and 3a-3c.
  • grid 7 has a central hub 8 on which there are rotatably mounted a plurality of opposite pairs of sectors 9, three in this case, which can be overlapped and are mutually connected so as to allow their dragging through a single control.
  • the outermost pair of sectors has a central knob 10 by rotating which in the clockwise direction it is possible to go from the configuration of maximum opening of fig.3a (the passage area corresponding to the hatched surface), to the intermediate configuration of fig.3b and then to the configuration of minimum opening of fig.3c.
  • the grid with the overlapping sectors 9 is just an example of a possible device for choking opening 6, said device being possibly made in several other equivalent ways such as with a horizontal or vertical shutter, or a radial diaphragm and the like.
  • An electromechanical adjustment can be achieved through the device illustrated in the second embodiment of fig.4.
  • opening 4 of fan 1 is choked by a gate 11 (in broken line in the open position) mobile under the action of a thermoactuator 12.
  • Thermoactuator 12 is particularly advantageous from an economical point of view, in that it is a cheap component and can be electrically connected in parallel with motor 5 without requiring an additional output on the timer.
  • gate 11 and thermoactuator 12 are just examples of a possible device for choking opening 4, whose passage area can also be adjusted with mechanisms using shutters, valves, cocks, etc.
  • a second gate could be provided on duct 2 to adjust the flow of moist air so as to achieve a more precise mixing of the discharged air, possibly in combination with the above-mentioned gate 11.
  • the adjustment device could also include a humidity sensor which detects the humidity percentage of the air discharged through outlet 3 (flow D) and transmits said information to the control unit.
  • a humidity sensor which detects the humidity percentage of the air discharged through outlet 3 (flow D) and transmits said information to the control unit.
  • the user can set a desired value of the humidity percentage of the discharged air and the opening of gate 11 will be automatically adjusted to keep said set value.
  • the drying cycle can end when the humidity sensor detects that the discharged air has reached a humidity percentage lower than a limit value, roughly corresponding to the percentage of the ambient air. In this way the duration of the cycle is always the minimum required to achieve a complete drying, regardless of the setting performed by the user.
