  • Patent number: 8938835
    Abstract: A washing machine and a method of controlling a washing machine are provided. The washing machine may include a drum in which laundry is provided and is rotated. The drum may operate at a first speed such that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum. An unbalance amount or a first speed operation time of the drum, which is detected when the drum operates at the first speed, may be determined. When an abnormality occurs, rotation of the drum may stop or decelerate. Accordingly, at the time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

  • Patent number: 8365334
    Abstract: A washing machine and a method of controlling the washing machine are provided. According to the washing machine and method of controlling the washing machine, the drum is operated at a first speed so that part of laundry within the drum tumbles and another part of the laundry adheres to the drum. When an unbalance amount of the drum operating at the first speed is a first specific value or less, the speed of the drum is increased to a second speed so that all of the laundry adheres to the drum. When an unbalance amount of the drum detected during the increasing to the second speed is a second specific value or more, the rotation of the drum is decelerated. Accordingly, at a time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

  • Patent number: 8302232
    Abstract: The present invention relates to a washing machine and a method of controlling the washing machine. According to a washing machine and a method of controlling the washing machine in accordance with the present invention, a drum operates at a first speed so that part of the laundry tumbles within the drum and another part of the laundry adheres within the drum. The drum operates at a second speed lower than the first speed so that an amount of the tumbling laundry is more increased than at the first speed. Accordingly, at the time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.
