Definitions

  • the present invention relates to dishwashing machines, and in particular to a dishwasher cycle suitable to achieve better washing results and to reduce the water consumption.
  • the user wishes to delay the start of the washing cycle even if the machine is fully loaded. This may be useful to prevent overlapping of operation with other domestic appliances, or to use the machine during a low fare period in case there are different fares for low and high consumption periods.
  • the cycle start delay is set through a timer which will start the machine at the desired time.
  • a first drawback is a greater water consumption since when the washing is carried out the cycle starts from the beginning regardless of the soaking cycle having been previously carried out or not. Therefore all the water consumption during the soaking cycle is an additional consumption.
  • a second drawback stems from the fact that the soaking cycle must be programmed by the user separately from the complete washing cycle, the latter being delayed or not. In other words, if the user forgets to set the soaking cycle after loading the machine, the washing result will not be completely satisfactory.
  • the object of the present invention is to provide an operation cycle and a dishwasher which overcome the above-mentioned drawbacks.
  • the first advantage of the present cycle is to prevent any additional water consumption when the soaking cycle is carried out.
  • the second advantage of this operation cycle is that it does not require a separate setting of the soaking cycle when the user sets a start delay for a delayed cycle. This assures a good washing result and saves the user the effort to remember the need for a double setting.
  • a device of the dishwasher includes a timer T, a programmer P, a washing pump L and a draining pump S.
  • the programmer P controls as usual the pumps L and S in order to carry out the various steps of the washing cycle, and the timer T in turn controls the activation of the programmer P when a start delay is set.
  • the timer T also directly controls the pumps L and S. In this way, when the timer T is activated to delay the cycle start, not only does it provide the deactivation of the programmer P until the desired time is reached but also immediately intervenes on the pumps. In particular, the washing pump L is run for some minutes in order to load the water in the tank and carry out the soaking, whereas the draining pump S is kept deactivated.
  • the machine stops with the water in the tank, ready for the complete washing cycle at the preset time.
  • the tank is already filled with water, when the complete cycle is started there is no additional water loading but the soaking water is re-used. In this way there is achieved the object of reducing the water consumption, and the soaking is automatically carried out by the machine when a start delay is set through the timer T.
