Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for operating a 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. 2. The method according to claim 1 , wherein the open-loop or closed-loop control device controls the pendulum rhythm depending on the type of laundry. 3. The method according to claim 1 , wherein the open-loop or closed-loop control device controls the pendulum rhythm using open-loop or closed-loop control in such a way that the pendulum rhythm varies depending on a time period. 4. The method according to claim 1 , wherein the open-loop or closed-loop control device controls the pendulum rhythm depending on a residual moisture in the laundry. 5. The method according to claim 2 , wherein the open-loop or closed-loop control device controls the pendulum rhythm using open-loop or closed-loop control in such a way that a pendulum deflection of the pendulum rhythm is greater the heavier the type of laundry and/or the longer a time period and/or the greater a residual moisture content. 6. The method according to claim 4 , wherein the open-loop or closed-loop control device determines the residual moisture as a function of time. 7. The method according to claim 1 , wherein the steam is conducted into the drum from below, based on an operational installation position of the washing machine. 8. The method according to claim 1 , wherein the open-loop or closed-loop control device controls a maximum pendulum deflection of the pendulum rhythm depending on a maximum rotational speed of the drum at which the drum is rotated at the maximum during the pre-ironing phase (Vb). 9. The method according to claim 1 , wherein a temperature of the steam is <50° C. 10. A 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 which is designed and configured to control a method using open-loop or closed-loop control according to claim 1 .
