  • the object according to the invention is achieved by a laundry care device with a laundry drum for receiving laundry, a drum drive for rotating the laundry drum, with a torque detection device for detecting a torque of the laundry drum and a controller for controlling the drum drive, the controller being designed To drive the drum drive during a rotation time interval in order to rotate the laundry drum at a first rotation speed when the detected torque falls below a torque threshold, wherein the controller is designed to drive the drum drive during the rotation time interval to rotate the laundry drum at a second rotation speed when the detected Torque exceeds the torque threshold, wherein the second rotation speed is less than the first rotation speed, and wherein the controller is configured, the second rotation ns speed depending on the detected torque of the laundry drum to avoid damage to the laundry in the laundry drum.
  • the torque increases when the laundry drum rotates and the laundry in the laundry drum can be damaged under certain circumstances. If the detected torque falls below the torque threshold value, the laundry drum can be rotated at a maximum first rotation speed during a rotation speed control of the control by the drum drive, in order to ensure an advantageous laundry care of the laundry during the laundry care process.
  • the control changes from the rotation speed control to the torque control, the laundry drum being rotated by the drum drive with a second rotation speed that is reduced compared to the maximum first rotation speed.
