Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the degree of contamination of the washing liquid is determined in a program-controlled dishwasher in one of the washing steps, for example the pre-washing step, the cleaning step, the intermediate washing step or rinsing steps.
  • a pressure sensor is arranged in the flushing liquid path, which is supplied with flushing liquid by a circulating pump, by means of which, when the circulating pump is operating, the magnetic valve in the water supply is opened in at least one program step when the pressure drops below a predetermined minimum due to an increased degree of contamination of the flushing liquid.
  • the individual rinse cycles are initially operated with a minimum amount of rinsing liquid.
  • the invention has for its object to provide a method according to the preamble of claim 1, by which a further reduction of water and energy consumption is made possible with little contamination of the dishes to be washed.
  • the amount of water required for the proper functioning is let into the washing container of the dishwasher at the beginning of each washing cycle. If an actual degree of soiling that is below a predetermined degree of soiling assigned to the respective rinse occurs during the course of the rinse cycle to be processed, then the current rinse can either be interrupted and the rinse liquid pumped out prematurely or, in the case of very little soiling, can also be taken over into the immediately subsequent rinse.
  • the pre-rinse cycle and the subsequent cleaning cycle are particularly suitable for this. This either only shortens the program duration accordingly or saves the liquid required for one of the two rinse cycles. If partial emptying is provided within the cleaning process in which the washing liquid is heated up to remove particularly high levels of contamination, then this partial emptying and refilling to the original level can also be dispensed with if there is little contamination found in the cleaning process.
  • the number of subsequent rinse cycles can also be reduced, either rinsing with a liquid filling over the entire time of all intermediate rinsing cycles or skipping the intermediate rinsing cycle (s) to be hidden. This reduction in water changes also saves water.
  • the pressure lines (4, 5) branch off from a flow reversing device (6), for example a continuously rotating rotary valve, which is connected to the pressure port (7) of a circulation pump (8).
  • a flow reversing device (6) for example a continuously rotating rotary valve, which is connected to the pressure port (7) of a circulation pump (8).
  • an intake (9) leads into a drain pan (10) provided in the bottom (11) of the washware container (1) and through funnel-shaped fine sieve (12) towards the interior (13) of the washware container (1) is covered.
  • the fine sieve (12) is in the lower part in a cylindrical, vertically downward fine sieve cylinder (14) which opens into a drain shaft (15).
  • a drain connection (16) leads from the drain shaft (15) to an emptying pump, not shown.
  • a coarse sieve (17) is located within the fine sieve cylinder (14).
  • the washware container is filled with liquid via a water line (18) with the controllable valve (19) switched on, which is controlled by a program switching device (20) that also controls the circulation pump (8) and other electrical components.
  • At least one sensor (21) is arranged in the washing system which outputs a control signal dependent on the determined degree of contamination to the program switching device.
  • Different degrees of soiling can also be predetermined in different rinse cycles as a starting point for the determination of a lower or increased level of soiling.
  • the sensor (21) can be designed as a pressure sensor (21.1) which is connected to the pressure port of the circulation pump. However, pressure sensors (21.2 or 21.3) can also be connected to the pressure lines (4) or (5) to the spray arms (2) or (3). A pressure sensor (21.4) can also be assigned to the intake port (9) of the circulation pump (8). However, the sensor (21) can also be designed as an optical sensor and respond to the turbidity of the rinsing liquid. In addition, it is also possible to use the sensor (21) to record the weight of the washing liquid or the flow rate of the washing liquid. However, the speed of the spray arms (2 or 3) can also be scanned with a sensor (21.5).
  • the power-dependent speed of the circulation pump (8) or the current consumption of the drive motor for the circulation pump (8) can also be detected with a sensor (21.6).
  • a sensor (21.6).
  • a bypass path can be provided in the flushing liquid path, in particular in the pipe system, in which a filter screen is arranged, a pressure sensor measuring the pressure loss or dynamic pressure occurring on the filter screen. This filter screen must be rinsed free after each rinse cycle in order to avoid falsification of the measurement result from previous rinse cycles.
  • the rinsing liquid with a pollution degree of 0 is practically pumped around in the rinsing system. If, for example, the pressure sensor (21.1) is used to determine the degree of contamination, then the maximum achievable pressure in the flushing system is present. If this pressure falls below a predetermined value in the course of the respective rinse cycle to be processed, which can be different in the pre-rinse cycle than in the cleaning cycle, this means normal or increased contamination of the items to be rinsed. There is then no reason to change a normal basic washing program according to FIG. 2. Accordingly, after the inflow of water for the pre-rinse cycle, the complete pre-rinse cycle specified by the program switching device is carried out.
  • the remaining time of the pre-rinse cycle is faded out or run over in the program sequence from the time the pressure measurement is evaluated. If the degree of contamination is very low, the rinsing liquid from the pre-rinse cycle can be used immediately for the subsequent cleaning cycle. There is then no need to change the water from emptying and supplying. If the degree of soiling is higher but below the normal value, it is advisable to change the water. In any case, however, the duration of the program will be reduced by the hidden part of the pre-wash cycle.
  • the rotational speed of the spray arms driven by recoil also changes, so that their rotational speed can also be a measure of the degree of contamination.
  • the power requirement for the drive motor of the circulating pump changes with the density of the rinsing liquid, which is dependent on the degree of contamination, so that the degree of contamination can also be determined by appropriate sensors via its speed or current consumption.
  • the liquid level in the drain pan changes with different delivery volumes of the circulation pump, so that the level of contamination can be determined from this using a level sensor (21.7).
