Definitions

  • the invention relates to a method for carrying out a washing program in a program-controlled dishwasher, in which rinsing liquid is circulated from a rinsing container to spray devices by means of a circulating pump during individual program sections and is removed from the rinsing container by means of an emptying device at least at the end of the rinsing program the program sequence takes place at least a partial replacement of the rinsing liquid in the washing container.
  • the EP 1 112 016 B1 discloses a method for operating a domestic dishwasher, in which at a partial replacement of the rinsing liquid, a drain pump and a circulation pump are operated, wherein the rinsing liquid to be pumped off and linenzu Jardinde is determined by the rotational speed of the circulation pump.
  • the drain pump is turned on until the circulation pump sucks in air, which is detected by measurable speed fluctuations. Then water is filled until the drain pump runs round again.
  • the level at which the circulating pump sucks air can be varied by different speeds of the circulating pump.
  • a low speed of the circulation pump causes a large amount of liquid to accumulate in the sump and consequently is pumped out, a high speed of the recirculation pump results in a low amount of drained flushing liquid.
  • a level sensor is proposed.
  • the invention raises the problem, in a method for carrying out a washing program of the type mentioned to determine the amount of water emptied from the washing container for the partial replacement as accurately as possible and by utilizing already existing technical aids.
  • the flushing liquid quantity emptied from the washing container for the partial replacement is determined on account of the signal change of a turbidity sensor arranged in a water path from the circulating pump to one of the spraying devices.
  • This can be used in many dishwashers already existing sensor and there are none additional components necessary. Due to the relatively significant signal change in a sinking of the liquid level below the level at which a stable running of the circulating pump is possible, the determination of the emptied amount is very accurately possible.
  • a drain pump can be used as an emptying device.
  • the rinsing liquid is freed of heavy impurities after the emptying process at the partial water change. It can then be rinsed with less rinsing fluid and lower pump pressure (reduced speed of the circulation pump). For this purpose, it is provided that the rinsing liquid quantity emptied for partial replacement is greater than the water quantity that has been filled again. It can be reduced to about half of the emptied amount of flushing fluid.
  • the replenished for partial replacement amount of water is determined by means of a flow sensor. As a result, the amount of water filled can be accurately determined and the consumption can be kept within narrow limits.
  • Dishwasher 1 shown has a designated 2 rinse tank, which opens into a collecting pot 3 in the lower area. From there, the accumulated liquid, usually cold or heated water with rinsing additives, fed via a suction nozzle 4 a circulating pump 5.
  • the washing container 2 two baskets 6 and 7 and a cutlery drawer 8 are arranged, which serve to hold the corresponding items to be washed.
  • the cutlery and crockery not shown in the drawings are irrigated by rotary spray arms 9 to 11, of which two baskets 6 and 7 and the drawer 8 each associated with a cleaning liquid.
  • the circulation pump 5 has three separate discharge nozzles 12 to 14, which are connected via Sprüharmzutechnisch 15 to 17 with the respective spray arm 9, 10 or 11 in combination.
  • the lower basket 6 associated spray arm 9 is supplied via the discharge nozzle 12 and the upper basket spray arm 10 via the discharge nozzle 13 with rinsing or cleaning liquid.
  • the upper installed on the Spipporaumdecke 2.1 spray arm 11 of the discharge nozzle 14 leads to liquid.
  • the spray arms can be operated together or alternately. To enable the latter, a water switch, not shown in the drawing would have to be integrated, for example, in the pump chamber of the circulation pump 5.
  • the drive of the pump impeller (not shown), through which the necessary pressure for supplying the spray arms 9 to 11 is established, is effected by a motor 18, turned on by the symbolized by the box 19 and the control line 20 electronic device control.
  • the device control 19 also influences the water supply to the washing container 2 by setting the duty cycle of a solenoid valve 21 and determines the run-in amount of water via an impeller 22.
  • the water supply is shown in the figure only symbolized by the two aforementioned components solenoid valve 21 and impeller 22, which is common in dishwashers water supply via a water bag and a softening device is not included, because it is irrelevant to the invention.
  • the collecting pot 3 is flanged by a further nozzle 23 to a drain pump 24.
  • the drain pump 24 is switched on and off via a further control line 25 of the device controller 19.
  • the washing program described consists of the steps of pre-rinsing, cleaning, intermediate rinsing, rinsing and drying, if necessary, the suppression or multiple repetition of individual program sections is possible.
  • an inlet of about 4 liters of water in the washing compartment 2 At the beginning of the pre-rinsing takes place an inlet of about 4 liters of water in the washing compartment 2, at the end of rinsing the complete emptying.
  • Complete water changes can take place between the individual program sections, in which the entire rinsing liquid is emptied and replaced by fresh water.
  • a partial replacement of the rinsing liquid can take place between individual program sections or within the program sections.
  • FIG. 2 shows qualitatively the signal of the turbidity sensor 26, the switch-on of the circulation pump 5, the switch-on of the drain pump 24 and the liquid level in the washing tank 2 in a time chart.
  • phase I the washing program is located in the Pre-wash section.
  • the washing container 2 In the washing container 2 are the aforementioned 4 liters of rinsing liquid, which are distributed by the circulating pump 5 at a constant speed n K on the spray arms.
  • the drain pump 24 is turned off, the signal of the turbidity sensor 26 is at a high level, which may increase even more depending on the respective contamination of the washing liquid.
  • phase II the partial replacement of the rinse liquid begins with a draining process.
  • the drain pump 24 is turned on, the circulation pump 5 is still operated at the speed n K.
  • the liquid level in the collection pot 3 drops below the upper edge of the intake manifold 4. In this situation, the transition to phase III begins.
  • the circulating pump 5 then sucks air, thereby reducing the pressure in the discharge nozzle 12 to 14. Finally, the circulation pump 5 no longer creates liquid to transport it to the level of the turbidity sensor 26. This lowers the signal of this sensor 26 from the high level to a low level.
  • the device control 19 detects this and turns off the drain pump. This completes the emptying process for the partial replacement.
  • the amount of liquid that is emptied during part replacement depends on the rotational speed of the circulating pump 5. The higher the speed, the more liquid circulates in the washing tank 2 and the lower the liquid level in the collecting pot 3. Therefore, at high speeds only a small amount is emptied until reaching the low level, at low speeds, a large amount.
  • the speed n K already used in the pre-wash cycle can be set so that the emptied partial amount is approximately one quarter of the contents of the washing container, which corresponds to one liter of liquid. This is an optimal value for a part exchange. For this reason, the circulation pump 5 can be operated continuously at the speed n K.
  • the device control 19 After emptying is also the partial exchange belonging filling the washing with fresh water (not shown).
  • the device control 19 now fills a half liter of fresh water in the washing.
  • the incoming quantity is then measured with the impeller counter 22.
  • the rinsing program is continued with the program section cleaning in which cleaning agent is added to the rinsing container 2 via a dosing device, not shown, and the rinsing liquid is heated to approximately 60.degree.
  • the specified temperature value corresponds to a normal program, with other programs lower or even higher final temperatures can be used.
