  • Patent number: 10619285
    Abstract: Provided is a control method of a washing machine. The control method of the washing machine including: an unbalanced position detection for detecting an unbalanced position; a balancer selection for determining a baffle plate which requires for water injection; a first water injection for injecting adjusted water to the baffle plate farthest away from the unbalanced position by a water supply valve when water needs to be injected to at least two baffle plates; an unbalance amount detection for detecting a transition of the unbalance amount of the washing tub; and a water injection switching for switching the water injection from the water supply valve to a water supply valve when the unbalance amount detected by the unbalance amount detection has turned to an increase.

  • Publication number: 20190010652
    Abstract: Provided is a washing machine. A baffle of the washing machine, which serves as a balancer, includes: a partition portion for suppressing a flow of adjusted water that is injected from a top end side by a water injection device toward a base end side so that the adjusted water retains at the top end side; and an outlet portion for discharging the injected adjusted water from the base end side of a washing drum.
