A detergent activation method for a cleaning appliance having a rotatable non-ribbed drum for holding the textiles) and includes a step of supplying a feed signal to a feed unit of the cleaning appliance. The feed signal causes the cleaning liquid to be fed into a suds container until a predetermined target fill level in the drum is reached. In the supplying step, a motion signal may be supplied to a drive of the cleaning appliance when the target fill level is reached, wherein the motion signal causes a rocking rhythm of the drum. The rocking rhythm defines successive rotational motions of the drum at increasing rotational speeds without a complete revolution of the drum. In the supplying step, a stop signal may be supplied to the drive when a final rotational speed of the rocking rhythm has been reached, to cause the rotational motions of the drum to stop.

A method for executing a spin program for a cleaning appliance having a rotatable, non-ribbed drum. A first motion signal is supplied which causes a first rotational motion of the drum in a first direction until the drum has reached a first target rotational speed. A second motion signal is supplied that represents a second rotational motion in a second direction until the drum has reached a second target rotational speed greater than the first target rotational speed. Further first and second motion signals are supplied which causes a further first and second rotational motions in the first and second directions until the drum has reached a further first and second target rotational speeds greater than the second and first target rotational speeds, respectively. A third motion signal causes a third rotation of the drum at the predetermined maximum rotational speed in the direction of the preceding rotational motion.

A washing machine and method for operating a washing machine having a suds container and a non-ribbed drum. During rotation of the drum in a subcritical rotational speed range, the method includes determining an average value, a minimum, and a maximum of an oscillation of a physical variable relating to the drum or the motor, forming an overall average value from the determined average values, subtracting the overall average value formed from the corresponding minimum determined per oscillation and the corresponding maximum determined per oscillation to calculate a maximum value and a minimum value per oscillation, respectively. In each case an amount is formed from the respective calculated maximum value and an amount is formed from the respective calculated minimum value, a standard deviation from the amounts is determined, and a loading situation where laundry is rolling in the drum is determined based on the determined standard deviation.

A washing machine and a method for operating the washing machine having a suds container for receiving water, a rib-free drum, which is rotatably mounted in the suds container, for receiving laundry, a motor for driving the drum, and an open-loop or closed-loop control device, wherein the method has a pre-ironing phase (Vb) for pre-ironing of the laundry located in the drum, during which phase steam is conducted into the drum and the drum is moved by means of the motor into a right-left pendulum motion, the pendulum rhythm of which is controlled using open-loop or closed-loop control by means of the open-loop or closed-loop control device in such a way that the drum is at least intermittently untouched by the laundry.

A washing machine and method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum provided with stamped portions rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device. During rotation of the drum in a subcritical rotational speed range, the method includes sampling a variable related to the drum or the motor over a predetermined period of time to determine time signals of the variable, executing a frequency analysis of the time signal of the variable to determine frequency components of the variable in a predetermined frequency range, summing the frequency components at predetermined frequencies of the predetermined frequency range, and detecting, depending on the sum of the summed up frequency components, whether a loading situation where laundry is sliding in the drum is present.

Method for operating a washing machine, and washing machine

A washing machine and method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device, wherein the method has a step for rearranging the laundry in the drum. The drum is caused to execute a right-left motion by means of the motor so as to cause a rocking motion of the laundry at a rocking frequency, the predetermined rocking amplitude of which is adjusted such that a laundry fall is implemented in which the laundry falls from a first region of the drum into a second region of the drum.
