  • the washing machine additionally has a load sensor.
  • the load sensor is advantageously arranged in the tub and connected to the control device.
  • the load sensor is preferably used to determine the mass of laundry items in the laundry drum. This enables, in particular, a determination of the loading amount for operating programs, with a total water consumption for the loading amount being specified and stored in the control device. Then, in particular, an exact adaptation of the size of the first volume V start of aqueous liquid is also possible in the pretreatment phase. This has the advantage that if the loading amount is precisely known, the first, second and third volumes can be selected without exceeding the total amount of water predetermined for the loading amount. This further reduces the resources required for treating the laundry items.
  • the washing machine additionally has a heating device for heating the aqueous liquid in the tub and a temperature sensor for measuring the temperature of the aqueous liquid in the tub.
  • the heating device in particular in the form of a flow heater, can also be arranged in a circulation line.
  • the heating device and the temperature sensor can advantageously be controlled by the control device. In this way, both the temperature T Start of the aqueous liquid in the pretreatment phase and the temperature T Wash in the washing phase can be determined and thus precisely controlled by the control device.
  • washing mechanics that is generated periodically loosens the dirt in the textile fibers so well that the washing performance is further improved in the washing phase that follows the pretreatment phase.
  • the treatment agent used can be used more efficiently in the washing phase, so that there can also be savings in, for example, washing agents (detergents).
  • the washing machine 1 shown schematically contains a rotatably mounted drum 2 with items of laundry 8 in a tub 3.
  • the washing machine 1 also has a fresh water supply device, which consists of a valve 5 controllable by the control device 4, a flow sensor 15 and a fresh water supply line 6.
  • the fresh water supply line 6 is routed via the dosing device 7 for treatment agent, so that, if required, treatment agent can be flushed from the dosing device 7 into the tub 3 by means of fresh water supply via the fresh water supply line 6.
  • the drum 2 is driven by the drive motor 11.
  • the drive motor 11 is a brushless and therefore low-noise drive motor 11.
  • the washing machine 1 also has a pump circulation system consisting of a pump circulation line 9, a tub outlet 10, a tub inlet 14 and a tub 12.
  • a pump circulation system consisting of a pump circulation line 9, a tub outlet 10, a tub inlet 14 and a tub 12.
  • an aqueous liquid for example a pretreatment liquid in the pretreatment phase or a washing liquor in the washing phase, can be pumped out of the tub 3 by the drain pump 12 via the tub outlet 10 and via the pumping line 9 and the tub inlet 14 back in the tub 3 to be led back. In this way, circulation of the aqueous liquid is made possible.
  • the drain pump 12 is also connected to a sewer line 13.
  • a three-way valve not shown here, which can be controlled by the control device 4, enables the pumping operation to be switched from the pumping system 9, 10, 12, 14 to the sewage line 13. In this way, if necessary, aqueous liquid can be pumped out of the tub 3 and disposed of, in particular also the volume V rem .
  • a second drain pump can alternatively be used.
  • a volume V start of 17 L fresh water is introduced into the tub 3 via the fresh water supply line 6 at the beginning of the pretreatment phase.
  • the control device 4 controls the valve 5.
  • the fresh water supply line 6 has the flow sensor 15, which is connected to the control device 4.
  • the tub 12 is switched on so that the aqueous liquid is circulated through the tub outlet 10 via the pumping line 9 and the tub inlet 14.
  • the tub inlet 14 is arranged in such a way that the items of laundry 8 are exposed to the aqueous liquid from above. This enables a particularly efficient use of the aqueous liquid for wetting and finally for washing the laundry items 8.
  • the tub inlet connected to the circulation line can be at a loading opening of the The tub and the drum, in particular on a cuff arranged between the tub and the housing of the washing machine for sealing the loading opening.
  • the aqueous liquid returned to the tub can be brought directly into the drum and thus onto the items of laundry. It is advantageous if the drum is rotated at a speed greater than the application speed, since the returned liquid is then brought onto the items of laundry lying on the jacket of the drum and is pressed through the items of laundry due to the forces acting during the rotation of the drum . This promotes rapid wetting of the items of laundry, detachment and removal of dirt from the items of laundry.
  • the sequence ⁇ t 1 , D 1 and ⁇ t 2 , D 2 is repeated at least twice in this way, it being possible to change the direction of rotation, in particular also during the first time segment ⁇ t 1 .
  • a volume V rem 2L of the aqueous liquid and thus, in addition to dissolved impurities, in particular also insoluble dirt particles, is then pumped into the sewage line 13 with the aid of the drain pump 12.
  • a volume V add 2 L is supplied to the tub 3 via the fresh water supply line 6.
  • the fresh water is passed over the metering device 7 in such a way that the amount of treatment agent M TWash contained therein is also flushed into the tub 3. Then the washing phase starts.
