摘要： The invention relates to a spin extractor for extracting liquid from wet laundry by rotating a drum with the laundry contained therein at high speed about a horizontal axis. In an inventive spin extractor, while an operation controller controls the speed of the drum so that the laundry is slightly pressed on the inner peripheral wall of the drum by centrifugal force and rotates with the drum, a position detector detects the position of an eccentric load due to the laundry as a first position. Then, the speed of the drum is raised to a second speed for weak extraction, which is lower than a predetermined maximum speed for extraction, and the position detector detects the position of the eccentric load as a second position. A quality determiner checks the displacement of the second position from the first position to determine the uniformity in extraction quality of the articles, where the extraction quality of an article represents how easily liquid is extracted therefrom. When the uniformity in the extraction quality is low, the weights of the articles decrease unevenly through the weak extraction, which causes a change in the position of the eccentric load. So, when, the displacement of the position is greater than a preset value, the operation controller sets an extraction speed lower than the maximum speed, and rotates the drum at the extraction speed during the extraction, whereby abnormal vibration is avoided.
