- the laundry care appliance 100 comprises a door 103 for loading the laundry care appliance 100 with laundry.
- 2 shows a schematic view of a laundry care appliance with a controller for controlling a drum drive of the laundry care appliance.
- the laundry care device 100 comprises a suds container 105 for holding washing liquid and a laundry drum 107 arranged in the suds container 105 for receiving laundry 109.
- the tub 105 has a drain opening 1 1 1, which is arranged on an underside of the tub 105.
- the discharge opening 1 1 1 is connected to a line 1 13.
- a pump 1 15 for pumping washing liquid through the line 1 13 is arranged.
- the pump 1 15 is designed to pump washing liquid from the discharge port 1 1 1 from the tub 105 and pump out the pumped washing liquid through the line 1 13 and through a Ausnaturalö réelle 1 17 from the laundry care device 100.
- the pump 1 15 is connected by a pump connection 1 19 with a controller 121 of the laundry care device 100.
- the controller 121 is configured to control the pump 15.
- the laundry care device 100 further has a drum drive 123 for rotating the laundry drum 107, which is designed to rotate the laundry drum 107 at different rotational speeds.
- the drum drive 123 is connected to the controller 121 through a drum connection 125.
- the controller 121 is configured to control the drum drive 123.
- the laundry care apparatus 100 further comprises a torque detecting device 127 for detecting a torque of the laundry drum 107.
- the Torque detecting means 127 is connected to the controller 121 through a device connection 129 and is connected to the drum drive 123 through a drum drive connection 130.
- the laundry care apparatus 100 further comprises a program selector 131 for selecting a plurality of selectable laundry care programs.
- the program selector 131 is connected to the controller 121 through a selection link 133.
- the rotational speed of the laundry drum 107 is controlled in response to specific inputs.
- the most important inputs are, in particular, the type of textile of the laundry 109 and the type of the selected laundry care program.
- the laundry drum 107 is rotated during a laundry maintenance program at a maximum rotational speed.
- the maximum rotation speed can be either predetermined or dynamically regulated.
- the maximum rotational speed may depend on the weight of the laundry 109 in the laundry drum 107, the temperature of washing liquid in the tub 105, the humidity or a manual input by the user.
- the disadvantage of controlling the maximum rotational speed in conventional laundry care appliances 100 is that a reduction in the rotational speed of the laundry drum 107 does not necessarily mean that the laundry care process for the laundry 109 is performed gently. For example, if laundry 109 has been jammed in laundry drum 107, drum drive 123 will try to reach the maximum rotational speed, thereby increasing the torque of laundry drum 107 loaded with laundry 109 and possibly causing damage to laundry 109.
- the controller 121 is designed to control the drum drive 123 during a rotation time interval in the course of a rotational speed control in order to rotate the laundry drum 107 at a maximum first rotational speed, if that caused by the Torque detection means 127 detected torque of the laundry drum 107 loaded laundry drum 107 falls below a torque threshold.

However, if the detected torque should again exceed the torque threshold, the controller 121 reverts from the rotational speed control to the torque control, and the first rotational speed is again reduced to the second rotational speed.
- the controller 121 increases the second rotation speed only to the first rotation speed when the detected torque is less than the torque threshold value by a torque difference value, or the controller 121 reduces the first rotation speed only to the second rotation speed when the detected torque exceeds the torque threshold value by one Torque difference value exceeds. If the Torque difference value has a sufficient size, it can be prevented that too often between the rotational speed control and the torque control is changed.
- the torque threshold may include a predetermined or a dynamic torque threshold.
- the controller 121 may determine the torque threshold value, for example, in dependence on the weight of the laundry 109 detected by a weight detection device and / or in dependence on a temperature of the washing liquid detected by a temperature sensor.
- the controller 121 may further consider the laundry maintenance program selected by the user by means of a program selector 131.
- the torque threshold value may also change during a laundry care operation, and may have different values for dry and damp laundry 109 in the laundry drum 107, for example.
- the controller 121 may be configured to detect the rotational speed of the laundry drum 107 and to deactivate the drum drive 123 or to drive the drum drive 123 to drive the laundry drum 107 in an opposite rotational direction when the detected rotational speed is less than a rotational speed threshold. This ensures that, in the case of a sharp drop in the rotational speed below the rotational speed threshold, it is ensured that washing 109, possibly jammed on the laundry drum 107, can reliably be released again by deactivating the drum drive 123 or by changing the direction of rotation of the laundry drum 107, thereby damaging the Laundry 109 can be avoided.
- the advantage of the laundry care device 100 according to the invention is, in particular, that a corresponding control of the rotational speed of the laundry drum 107 enables a particularly effective and at the same time gentle laundry care process which avoids or at least reduces damage to sensitive laundry items.
- a slow change of the rotational speed of the laundry drum 107 can be ensured, whereby the laundry 109 can be turned particularly gently in the laundry drum 107.
- the torque detecting means 127 includes a power detecting element for detecting an electric power of the drum drive 123, a further sensor may be omitted.
- the torque-dependent control of the rotational speed can be activated or deactivated as required by the user of the laundry care device 100 in order to achieve particularly gentle laundry care of the laundry 109.

- the controller 121 changes from the Rotation speed control on the torque control.
- the controller 121 in this case controls the drum drive 123 to rotate the laundry drum 107 at a second rotational speed, which is less than the maximum, first rotational speed 155.
- the torque control is active and the controller 121 controls the second rotational speed in response to the detected torque of the laundry drum 107 loaded with laundry 109.

- the third curve 159 shows the course of the supply current of the drum drive 123. As shown in the third curve 159, the supply current of the drum drive 123 changes significantly during the wash cycle. The torque proportional to the supply current of the drum drive 123 of the laundry drum 107 loaded with laundry 109 thus also changes significantly.
