Specifically, the rotating drum 4 is rotated at 45 rpm for 20 seconds, and the vibration detector 16 detects an average vertical acceleration for 20 seconds.

For example, if you put about 4kg of cotton clothes, double 8kg of washing water. For this reason, the rotation drum 4 is calculated to have 12 kg of cloth containing washing water.
  • the laundry in the rotating drum 4 depends on how the cloth is biased, a lump of cotton containing approximately 2 kg of water is lifted up to the top of the rotating drum 4 and dropped down toward the bottom of the rotating drum 4 Therefore, the rotating drum 4 easily sinks and uneven rotation occurs.
