Abstract: 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.

Abstract: 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.

Abstract: A cleaning appliance and method for operating a cleaning appliance having a suds container and a rotatable drum, wherein the drum is arranged in the suds container, and wherein an inside of a drum casing of the drum is smooth, apart from a plurality of nubs, for causing the cleaning liquid in the drum to execute a wave motion during a cleaning process. The cleaning appliance has a feed unit and a drive. The method includes supplying a feed signal to the feed unit, wherein the feed signal causes a cleaning liquid to be fed into the suds container until a predetermined target fill level is reached. The target fill level causes the textiles to float inside the drum. The method includes supplying a motion signal to the drive when the target fill level is reached in order to cause a rotational motion of the drum.

Abstract: A washing machine and method for operating a washing machine having a suds container for holding water, 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. The method allows the execution of a washing program (Wp) having a washing phase (Wa) and/or at least one rinsing phase (Sp), and includes feeding water into the suds container in a first region of the drum in at least one of these phases (Wa, Sp) up to a predetermined water level (h) that is selected such that the laundry floats in the water, and rotating the drum at a predetermined rotational speed such that water is released from a second region of the drum and falls onto the laundry.

Abstract: A cleaning appliance and method for operating a cleaning appliance with a rotatable, non-ribbed drum for the pre-treatment and main treatment of textiles. The method comprises a step of supplying a feed signal for feeding a cleaning liquid into a suds container until a predetermined initial fill level is reached. A saturation action causes the textiles to be pre-treated to be saturated with the cleaning liquid. The method includes reading in a fill level signal that represents a fill level of the cleaning liquid, and supplying a further feed signal for feeding the cleaning liquid into the suds container until a target fill level is reached. A motion signal causes a rocking rhythm of the drum for pre-treating the textiles to be pre-treated. After the pre-treatment, an unlocking of a drum door takes place in order to allow additional textiles to be added for a main treatment of the textiles.

Abstract: 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.

Abstract: A flanged-shaft apparatus (1) is configured for rotatably supporting a drum (4) in a washing machine having such a flanged-shaft apparatus (1). The flanged-shaft apparatus (1) has a connecting flange (2) configured to be arranged against a drum base (41) of the drum (4) and attached to the drum (4), and a drive shaft (3) arranged in the center of the connecting flange (2) and connected thereto for connection to a drive motor. The connecting flange (2) has a main element (21) formed from a steel sheet and a supporting element (22) formed from a further steel sheet. The main element (21) and the supporting element (22) are arranged one on top of the other along a longitudinal axis (L) of the drive shaft (3).

Abstract: A suds container for a washing machine includes plastic and is disposed so as to vibrate inside the machine housing, and includes first and second joint pieces. The first joint piece has a first bore therethrough and the second joint piece has a second bore therethrough aligned with the first bore. The first and second joint pieces are configured to fasten a vibration absorber with a fastening eye of the vibration absorber disposed between the joint pieces. A fastening element is at least partially received in the first and second bores and configured to fasten the vibration absorber. An S-shaped molded part is disposed on the joint pieces and includes third and fourth aligned bores and a first and a second arched area. The first arched area has a U-shape and is disposed between the joint pieces. The second arched area extends so as to overlap a free end of the first joint piece at an outer portion thereof.
