Definitions

  • the invention relates to a method for operating a washing machine and a washing machine.
  • Textiles are usually sorted for the washing process by color and suitable washing program or suitable treatment. Due to the different treatment of the laundry, there are several washings for "insensitive” to "very sensitive” textiles, which must be divided into cotton, easy-care, shirts, delicates etc., because the washing programs are tailored to the needs of the textiles. Thus, the temperatures, the washing rhythm, rinsing and washing levels and spin speeds in the individual washing programs are adapted to the sensitivity level of the textiles.
  • the lye temperature for the subsequent washing cycles must be brought several times to the selected temperature.
  • the invention thus presents the problem of providing a method for operating a washing machine and a washing machine with which the differently sensitive textiles can be washed in a single washing program.
  • the invention relates to a method for operating a washing machine with a tub for receiving washing liquid, a drum for receiving laundry, a loading opening for loading the drum with the laundry and a door for closing the loading port, comprising a washing phase comprising the steps of feeding the washing liquid into the tub to a first washing liquid level and washing the laundry in a first part washing phase with a first partial washing phase period, performing a first washing stop during which the door of the washing machine is unlocked for opening , which closes the loading opening during the first partial washing phase, and if a refilling of laundry in the drum during the first wash stop is activated, supplying washing liquid in the tub to a second washing liquid level, which is higher than the first washing liquid level and washing the laundry in a second partial wash phase with a second partial wash phase period.
  • the above steps are sequentially performed in the illustrated order.
  • the energy consumption of the washing machine can be reduced by using the already introduced energy of the first partial washing phase for the second partial washing phase.
  • water and time are saved, because for the Operawaschphasen not several rinsing and spinning processes are performed.
  • washing liquid is to be understood as meaning water which optionally has washing agent and / or care agent.
  • washing machine is to be understood as a washing machine such as a washing machine and a combination appliance such as a washer-dryer.
  • the washing machine can be a household used in a private household or a commercial washing machine.
  • the first partial wash step is continued with the second partial wash phase period if no replenishment of the wash into the drum is activated during the first wash stop.
  • the first partial washing step is preferably performed over the first and second partial washing phase periods, and then the first washing stop is performed. This ensures that the laundry in the first partial washing step is not washed for too short a period of time if no replenishment of laundry is provided.
  • the method comprises the steps of: performing a second wash stop after the second partial wash phase duration has elapsed, during which the door of the washing machine is unlocked for opening, and if refilling of laundry into the drum is activated during the second wash stop, supplying Washing liquid in the tub to a third washing liquid level higher than the first and second washing liquid levels, and washing the laundry in a third Operawaschphase with a third Operawaschphasenzeitdauer; or if no replenishment of the laundry into the drum during the second wash stop is activated, continuing the first or second partial wash phase with the third partial wash phase period.
  • This configuration allows a washing of laundry with two or three different degrees of sensitivity.
  • the washing phase may have one to three partial washing phases, depending on whether the user has set before or during the start of the washing program that he wants to refill laundry once or twice or how many partial washing phases the user has programmed.
  • Replenishment of the laundry into the drum during the first or second wash stop is activated if the user has entered or programmed this into the washing machine before or during the start of the washing program.
  • the user may indicate that he wants to wash two or three types of fabrics from the group of insensitive, delicate and very delicate textiles.
  • the user may indicate that two or three partial washing phases are to be performed at different washing temperatures, for example at 60 ° C, 40 ° C and 30 ° C, respectively.
  • a rotational speed during the first and second wash stops is preferably relatively low to 0 min -1 .
  • a duration of the first or second wash stop is preferably dependent on the guard temperatures of the first, second and third partial wash phase.
  • the washing machine is preferably in the waiting washing rhythm during first and second washing stops, respectively.
  • a rotational speed in rotational phases in which the drum is rotated during the first, second and / or third Operawaschphase decreases with increasing number of Operawaschphasen, takes a rotational phase time of the rotational phases with increasing number of Operawaschphasen and takes a rotation pause period of rotation breaks, the be carried out between the rotational phases, with increasing number of Operawaschphasen too.
  • the first, second and third partial wash phases are performed in the illustrated order, if they are activated respectively.
  • the first part wash phase is used for washing non-sensitive textiles and therefore preferably has a strong washing mechanics characterized by relatively high maximum speeds, relatively short rotational pauses and relatively long rotational phases
  • the second partial wash phase is used to wash delicate textiles and therefore preferably a normal one Washing mechanics, which is characterized by average rotational speeds, equal proportions of rotational breaks and rotational phases
  • the third sectionwaschphase used for washing very delicate textiles and therefore preferably has a low washing mechanics, characterized by relatively low speeds, relatively long rotational pauses and relatively short rotational phases is.
  • the Washing liquid level in the first partial washing phase preferably low, in the second partial washing phase medium and in the third partial washing phase high, relative to each other. This ensures that insensitive textiles are washed the longest and very delicate textiles the shortest and most gently.
  • a washing temperature during the first, second and / or third Operawaschphase decreases with increasing number of Operawaschphasen.
  • the maximum washing temperature in the second partial washing phase is preferably less than or equal to the maximum washing temperature in the first partial washing phase.
  • the washing temperature in the third partial washing phase is less than or equal to the maximum washing temperature in the second partial washing phase. This ensures that delicate or very delicate textiles that require a low wash temperature are not washed at elevated temperatures.
  • wash liquid is pumped out of the tub during the first and / or second wash stop.
  • the door is unlocked only after pumping. This ensures that no washing liquid flows from the tub through the loading opening in an area outside the washing machine, when the user opens the door of the washing machine in particular a front loader to refill laundry.
  • the washing liquid is pumped down to a washing liquid level p ist which is smaller than a washing liquid level p door - 10 mmWs, where p door is the washing liquid level which is in the tub at the lower level of the door, based on the operating set-up position of the washing machine. This ensures that no washing liquid escapes from the washing machine when the door is opened.
  • the first, second and / or third Halwaschphasenzeitdauer of one of the Operawaschphase associated pollution degree of the laundry depends.
  • the degree of soiling preferably changes the partial washing phase duration of the corresponding first, second and / or third partial washing phase by a factor in the range of 0.5 to 1.5.
  • selectable degrees of soiling such as "light”, "normal” and “strong” are stored in the washing machine, which the user can assign to the partial washing phases to be carried out during the washing phase.
  • At least one rinsing and / or spinning phase is carried out after the washing phase, wherein a washing liquid level in the tub during the at least one rinsing phase and a rotational speed of the drum during the at least one spin phase of the washing liquid level and the speed of the drum during the last carried out Operawaschphase depends.
  • the wash phase is preferably the only wash phase of the wash program.
  • the washing program preferably has an optional acquisition phase for detecting the laundry lot, the washing phase, at least one rinsing phase and a spinning phase. More preferably, the phases in the sequence shown represent the complete sequence of the washing program.
  • the washing phase has the first, second and / or third partial washing phase. Each partial washing phase has an optional detecting portion for detecting the laundry load, a washing liquid supplying portion for washing the washing liquid to the washing temperature required for the partial washing phase, and a washing portion for washing the laundry and an optional washing stop portion for unlocking the door ,
  • the invention further relates to a washing machine with a tub for receiving washing liquid, a drum for receiving laundry, a heating element for heating the washing liquid, a loading opening for loading the drum with laundry, a door for closing the loading opening and a control or regulating device, which is configured and / or configured to perform a method according to one or more of the embodiments described above.
  • Fig. 1 shows a flow diagram of a method according to the invention for operating a washing machine.
  • the washing machine has a washing tub (not shown) for holding washing liquid (not shown), a drum (not shown) for holding laundry 51, 52, 53, a loading opening (not shown) for loading the drum with the laundry 51, 52 , 53 and a door (not shown) for closing the loading opening.
  • step 0 marks the start of the washing program and is not part of the method according to the invention:
  • step 0 the user of the washing machine enters the following data into the washing machine: laundry 51 in the form of insensitive textiles with normal degree of soiling
  • laundry 52 should be washed in the form of sensitive textiles with a high degree of soiling at a washing temperature of 40 ° C.
  • laundry 53 should be in the form of very sensitive Textiles are washed with a slight degree of soiling at a washing temperature of 30 ° C, and starts a washing program with a washing phase, which has a first, second and third Operawaschphase.
  • the user has filled laundry 51 into the drum of the washing machine.
  • the washing liquid is fed into the tub until a first washing liquid level.
  • the washing liquid is heated to the washing temperature of 60 ° C and the laundry 51 is washed with a first Operawaschphasenzeitdauer and the first washing liquid level in the tub.
  • a first washing stop is carried out, during which the door of the washing machine is unlocked for opening, which closes the loading opening during the first partial washing phase 1.
  • the washing liquid is at least partially pumped out of the tub.
  • step 4 By entering the data in step 0, the user has activated replenishment of laundry 52 into the drum during the first wash stop 13. The user can now refill the laundry 52 during the first wash stop.
  • a controller or controller queries whether the second partial washing phase 2 has been activated by the user in step 0. If the controller determined in step 41 that no second sub-wash phase 2 had been activated by the user in step 0, which is not the case here, then step 42 would immediately follow step 41.
  • step 2 If, as in the present case, the second partial washing phase 2 has been activated by the user in step 0, the second partial washing phase 2 is started and the method continues with step 21, in which washing liquid is fed into the tub until a second washing liquid level is higher than the first washing liquid level.
  • step 22 the washing liquid is heated to the washing temperature of 40 ° C and the laundry 51, 52 washed within a second Operawaschphasenzeitdauer.
  • step 23 a second washing stop is carried out during which the door of the washing machine is unlocked for opening, which closes the loading opening during the second partial washing phase 2.
  • step 23 the washing liquid is at least partially pumped out of the tub.
  • the user can now refill the laundry 53.
  • the controller queries whether the third partial washing phase 3 is activated by the user. If the user has activated the third partial washing phase in step 0, as is the case in the present case, the third partial washing phase 3 is started and the method continues with step 31, in which washing liquid is fed into the tub until a third washing liquid level, which is higher than the second washing liquid level.
  • the washing liquid is heated to the washing temperature of 30 ° C and the laundry 51, 52, 53 washed within a third Operawaschphasenzeitdauer.
  • step 32 is followed by a step 6 in which at least one rinsing and spinning phase is carried out. If the controller had determined in step 42 that no third partial wash phase 3 had been activated by the user in step 0, which is not the case here, then step 6 would directly follow step 42.
  • step 6 In the at least one rinsing phase, first the washing liquid is pumped out of the tub, then washing liquid in the form of water is introduced into the tub and the laundry 51, 52, 53 is moved therein and finally the washing liquid is pumped out again, possibly being interspersed.
  • the drum is rotated at a speed at which the laundry 51, 52, 53 abut against a jacket of the drum, while washing liquid is pumped out of the tub.
