Definitions

  • the present invention refers to a clothes washing or dishwashing machine, in particular of the household type, which is provided with an appropriate electric circuit that, when associated with a timer means, enables a plurality of programmes to be set which differ from each other for their highest attainable temperature, wherein the rising phase of the temperature of the wash liquor can be interrupted selectively for a pre-determined time interval.
  • Clothes washing and dishwashing machines are known in the art the operation of which is controlled by wash cycle programming means, said cycle usually comprising at least a wash liquor heating-up phase, a wash liquor temperature holding phase, wherein said two phases are carried through when the washload holding drum is rotating regularly, and a final series of rinsing and spin-extraction phases.
  • Clothes washing or dishwashing machines are in particular known which are provided with a so-called "thermogradual" system for controlling the temperature of the wash liquor, such a system consisting in allowing one or more temperatures to be reached by energizing the heating element during one or more defined periods through appropriate configurations of the circuits and the programme sequence control switch.
  • washing programmes In view of making washing programmes to more strictly comply with the actual requirements of use, it is also a known technique, eg. from the patent specification FR 1.235.659, to enable the length of the washing time to be modified at will through the provision of additional timing means.
  • Such a solution gives only the possibility of modifying the washing time at constant temperature, but does not allow for any additional phases at pre-determined temperatures, differing from the nominal washing temperature, to be carried out within the same programme.
  • thermostop machines which are known in the art under the denomination of "thermostop” machines, share the characteristic that the ultimate, steady-state temperature of the washing liquor is reached with a single temperature-rise ramp.
  • water will be used in the following description to indifferently mean both washing liquor and rinse water. However, such a simplification will not affect the intelligibility of the exposure to any extent, owing to the context in which said term is actually used, as anyone skilled in the art will readily appreciate.
  • the present invention substantially relies on creating the possibility of introducing, both during the heating-up phase and the washing phase at the highest pre-set temperature, one or more time intervals which are caused to start when the temperature reaches a pre-determined value and during which the power supply to the heating element is cut off. According to such a mode of operation, the machine goes therefore on with the washing process, in particular keeping its washload-holding drum rotating regularly, while the power supply to the heating element is restored after each one of said time intervals, so that the washing programme can go on regularly until its end.
  • this enables washing phases at substantially constant temperature to be introduced in the programme, so as to be able to deal in a selective manner with the various types of soil in the washload during a pre-determined period of time, said phases being situated at temperature levels which are of course lower than the level of the highest pre-set temperature and are aimed at handling the type of soil in the washload that is more effectively removed at each one of said temperatures.
  • Figure 1 illustrates a graphical representation of the evolution of the washing liquor temperature in a 90°C washing programme.
  • Such a temperature evolution can be derived from said diagram for state-of-art machines by completely eliminating the time intervals indicated with the references t b , t c , t d on the abscissa, so that a single temperature rise phase would be obtained forming a single, straight temperature rise ramp from the initial value T 0 through to the final value at 90°C, without any dwelling time at the intermediate values of 40°C and 60°C.
  • a plurality of intervals of a pre-determined duration t b , t c , t d are planned to occur during the programme in an irregular succession, such intervals being in fact planned to start when the temperature of the washing liquor reaches respective values of 40°C, 60°C and 90°C.
  • the heating element provided to heat-up the washing liquor is de-energized, so that the programme, upon reaching said temperature values, undergoes a double effect: on the one hand there is a corresponding extension of the washing time, while this extension of the washing time is on the other hand is obtained by enabling the temperature to dwell exactly at the desired level which has been appropriately selected to cope with the type of soil which is particularly sensitive to and is best removable at precisely that temperature.
  • FIGs 2 and 3 illustrate on the contrary the evolution of the temperature of the washing liquor when a 60°C and 40°C washing programme according to the present invention is set, respectively.
  • Such graphical representations are quite readily and easily inferable and understandable by those who are skilled in the art, since they are the respective partializations of the diagram appearing in Figure 1, so that they do not need any further explanation.
  • a whole series of advantageous improvements of the present invention consists in providing the ability of defining, through appropriate control means adapted to be activated directly by the user, both the temperature or the temperatures at which said washing phases at substantially constant temperature are to occur and the duration thereof. Furthermore, the duration of each one of said intervals is adapted to be adjusted either individually for each temperature or in a common manner for all working temperatures reached in said intervals. Finally, in view of conferring the greatest possible extent of flexibility and, at the same time, simplicity to the machine, the duration of said intervals may be adapted to be adjusted either in a continuous manner or at fixed increments corresponding to discrete values.
  • the drum in order to further improve the washing performance of the machine, it is appropriate for the drum to be adapted to be driven at rotational speeds differing from the regular one during said washing phases at substantially constant temperature, so that the synergic effect of an intermediate washing action at a particular temperature for a pre-determined period of time, and at a rotating speed of the drum appropriately adjusted to suit that combination of programme, time and temperature, is actually able to ensure the best possible washing results.
