  • the third curve shows 163 different fill levels of washing liquid 129 in the lye container 105 during the two expulsion time periods 157-1 and 157-2.
  • the fill level of the washing liquid 129 reaches a fill level threshold value of 165 during the first bud break period 157-1, whereas the fill level of the washing liquid 129 does not reach the fill level threshold value of 165 during the second bud break period 157-2, but only reaches a reduced fill level value of 165-1.
  • the target level threshold value 165 depends on a variety of parameters, in particular on the amount of laundry, the type of laundry, the dry weight of the laundry, the total amount of washing liquid 129 in the tub 105, the amount of washing liquid 129 spun free from the laundry 127, the level of the spin speed 159, the geometry of the washing drum 107 and the geometry of the tub 105.
  • the reason for the different fill levels of washing liquid 129 during the first and second discharge time periods 157-1, 157-2 at the same discharge speed 159 is due to the unpredictable movement behavior of the laundry 127 in the rotating washing drum 107, which results in different quantities of washing liquid 129 being discharged from the laundry 127 in the first and second discharge time periods 157-1, 157-2.
  • the control unit 119 changes the flow rate during the process.
  • Fig. 5B In the fourth discharge period 157-4 shown, the rotational speed of the washing drum 107 depends on the fill level of washing liquid 129 detected by the fill level sensor 123.
  • the controller 119 increases the flow rate during the cycle.
  • Fig. 5B In the fourth discharge period 157-4 shown, the rotational speed of the washing drum 107 is increased to a higher discharge speed 159-1, thereby driving more washing liquid 129 out of the laundry 127, and the level of washing liquid 129 detected by the level sensor 123 in the tub 105 reaches the level threshold 165.
  • the difference between the increased output speed 159-1 and the output speed 159 is specifically set at a value of less than or equal to 50 rpm.
  • the fill level sensor 123 is activated for fill level measurement, in particular when the respective discharge time period 157 begins, i.e., when the rotational speed of the washing drum 107 reaches the discharge speed 159, or when a predetermined time period stored in the laundry care program has elapsed, which correlates with the start of the discharge time period 157.
  • the monitoring function of the fill level sensor 123 is correlated with the start of the discharge time period 157 in this case.
  • the fourth flushing period 157-4 ends when the measured fill level of the washing liquid 129 reaches the fill level threshold 165 within a predetermined time interval. As in Fig. 5B As shown, the control unit 119 terminates the fourth exit period 157-4 immediately when the detected fill level reaches the fill level threshold 165.
  • control unit 119 In order for the control unit 119 to be able to increase the output speed 159 to the increased output speed 159-1 during the corresponding output time period 157, there must be no imbalance in the rotating washing drum 107 to prevent damage to the washing drum 107. Such an imbalance can occur, for example, due to clumping of laundry 127 in the rotating washing drum 127.
  • the laundry care appliance 100 includes, in particular, an imbalance sensor designed to detect an imbalance of the rotating washing drum 107.
  • the imbalance sensor comprises, in particular, a power sensing element for detecting an electrical power value of the drum drive 109 of the washing drum 107, a device for detecting a deflection or acceleration of a vibrating system of the washing drum 107, and/or a 3D sensor for detecting a deflection of the washing drum 107 in all three spatial directions.
  • the control unit 119 is specifically designed to increase the rotational speed of the washing drum 107 to the increased rotational speed 159-1 only during the discharge period 157 if the imbalance sensor does not detect any imbalance of the rotating washing drum 107.
  • Fig. 6 shows a schematic view of a laundry care process according to a second embodiment.
  • the imbalance sensor detects during the Fig. 6 In the fifth output phase 157-5 shown, an imbalance of the rotating washing drum 107 occurs, so that in the subsequent sixth output phase 157-6 the control 119 reduces the output speed 159 to a reduced output speed 159-2 in order to avoid damage to the laundry care device 100.
  • the duration of the sixth removal period 157-6 is extended by a further time interval.
  • the fill level of the removed washing liquid 129 in the lye container 105 reaches the fill level threshold 165 after the sixth removal period 157-6.
  • the sixth budding period 157-6 ends when the further time interval of the sixth budding period 157-6 has elapsed. is, or when the recorded fill level of the washing liquid 129 reaches the fill level threshold value 165 during the sixth extrusion period 157-6.
  • Fig. 7 shows a schematic representation of a procedure for caring for laundry in a laundry care device.
  • the process 200 comprises, as a first process step, the activation 201 of the drum drive 109 to rotate the washing drum 107 with an ejection speed 159 by the control 119 during an ejection time period 157 in order to apply the laundry 127 received in the washing drum 107 to the washing drum 107 and to at least partially expel the washing liquid 129 bound to the laundry 127 from the laundry 127.
  • the second step of the process 200 includes the activation 203 of the level sensor 123 by the control unit 119 during the expulsion period 157 in order to detect a level of washing liquid 129 in the lye container 105 during the expulsion period 157.
  • the process 200 comprises, as a third process step, the activation 205 of the drum drive 109 by the control 119 during a further ejection period 157 following the ejection period 157, in order to change the ejection speed 159 of the rotating washing drum 107 depending on the detected fill level of washing liquid 129 in the tub 105.
