  • Object of the invention is to provide a method by which the energy consumption can be further reduced.
  • the inventive method for operating a dishwasher has at least the following steps: in a partial program step, a first amount of liquid is heated, the heated first amount of liquid is at least partially in heat-conducting contact with the interior of a washing container inside a Liquid storage stored in a further part program step, a second amount of liquid is heated, and
  • the method according to the invention allows the use of heat energy of liquids, in particular heated, to recover, which is otherwise lost with the pumping out in a house-side wastewater disposal system.
  • the circulated liquid quantity in the further part program step is at least temporarily heated, so that temperatures can be achieved, which can not be achieved alone by utilizing recovered heat energy.
  • it may also be provided to dispense with a heating in the further part program step, but only to heat up the recovery of heat energy liquid.
  • the circulated liquid quantity is heated only to a temperature equal to or below the temperature of the liquid stored in the liquid storage, so that no unnecessary energy for heating the liquid stored in the liquid storage must be applied.
  • liquid reservoir and the rinsing container are emptied simultaneously, while in a second, alternative embodiment it is provided that first the rinsing container and then the liquid reservoir are emptied.
  • the partial program steps preferably comprise at least one cleaning step and one final rinse step, wherein liquids are heated in each case during both partial program steps.
  • cleaning agent is added and the circulated liquid or rinsing liquor is heated to, for example, up to 65 ° C.
  • relaxation agents are added, which are in particular ensure a stain-free drying process of the dishes, with temperatures of, for example, 70 0 C are reached in this step.
  • At least one third partial program step without heating of liquid is provided between the two partial program steps.
  • This may preferably be an intermediate rinsing step, which serves in the rinsing container and the pump system To remove residues of detergent-added liquid or rinsing liquor remaining of the dishwasher, so as to ensure that detergent residues and added in the final rinse step relaxants do not affect each other in their negative effect.
  • a pre-rinsing step without heating of liquid is provided, in which liquid stored in the liquid store is used. Pre-rinsing serves to remove coarse dirt from items to be cleaned.

  • a spray arm 8 is provided in the washing container in the present embodiment.
  • a circulating pump 10 is provided, which is liquid-conducting with a arranged in the bottom region of the washing compartment 6 swamp, in which collects the rinsing of the wash ware to be cleaned rinse.
  • an engine 12 is provided, which is in communication with a control device 14 of the dishwasher 2.
  • a heating element for heating the circulated rinsing liquor, a heating element (not shown) may be provided.
  • a liquid reservoir 4 is provided, in which a quantity of liquid can be temporarily stored.
  • a drain line 24 is provided, which can be opened and closed by means of a drain valve 18, wherein the drain valve 18 is connected via a control line 16 to the control device 14.
  • a return line 26 is provided with which it is possible to reclaim rinse liquor from the washing container 6 in the liquid storage 4.
  • a return valve 20 is provided, which is also connected via a control line 18 to the control device 14.
  • further valves may be provided to block the supply line to the spray arm 8 in the washing container 6, if by means of the circulation pump 10 rinse liquor to be conveyed through the return line 26 into the liquid storage 4.
  • individual valves designed as a water diverter multi-way valve can be used, for example. Has a motor-adjustable disc.
  • a cleaning program comprising several program steps is run through, which may comprise, for example, the program steps of pre-wash, clean, intermediate rinse step and rinse-clean, and drying.
  • water or rinse liquor i. heated water with cleaning agents or rinse aid during at least two of these program steps, for example.
  • a rinsing liquor change of the circulated rinsing liquor takes place between the subprogram steps, that is, after completing a partial program step, the dishwasher is filled again with liquid or water.
  • a pre-rinse step may be performed, for example, after an amount of liquid has flowed into the rinse tank 6 through conduit means (not shown). Subsequently, the liquid quantity is circulated by the circulation pump 10 after appropriate activation of the motor 12 by the control device 14 and fed to the spray arm 8. After completion of the pre-rinse, the amount of liquid is passed after opening the return valve 20 through the return line 26 into the liquid reservoir 4, wherein a closed drain valve 18 prevents the rinse tank 4 emptied again.

  • the rinsing container 6 is filled again with an amount of liquid, and then the liquid is circulated by the circulating pump without being heated. Heating is effected solely by the heat transfer from the liquid reservoir 4 into the interior of the washing container 6, since the liquid stored in the liquid storage 6 has a higher temperature than prevails in the interior of the washing container 6. After completion of the Swiss Vietnamese archasars both the washing compartment 6 and the liquid storage 4 are emptied. This can be done sequentially, starting with the washing container 6 or at the same time.
  • the rinsing container 6 is filled again with an amount of liquid to carry out a rinsing step, and then the liquid is circulated by the circulating pump while it is further heated.
  • the rinse tank 6 can be emptied by means not shown, which allow to direct liquid into a household wastewater disposal system.
  • the amount of liquid present in the washing container 6, ie water added with relaxation agent or rinse aid, is subsequently passed into the empty liquid storage 4 through the return line 26.
  • the liquid quantity temporarily stored in the liquid storage 4 can be conducted into the rinsing container 6 by opening the drainage valve and used to carry out a pre-rinsing step.
  • the method according to the invention can also be used to achieve energy savings in the case of modifications of the program sequence in which heating of the liquid or rinsing liquor is also provided during the intermediate rinsing and / or pre-rinsing step, or in which the intermediate rinse and / or Pre-rinse step are hidden.
