In the scheme 3, in the first running state, the inner barrel and the impeller rotate in the same direction, the rotating speeds of the inner barrel and the impeller are different, and when the inner barrel and the impeller rotate in the same direction but at different speeds, rotating running water with high strength can be formed, so that the washing efficiency is guaranteed.
Further, the inner barrel and the impeller rotate in the same direction and at different speeds, and the difference value of the rotating speeds of the inner barrel and the impeller is a fixed value or a variable value; therefore, the water flow with certain strength can be preset, and a stable washing program is also facilitated to be formed.
In the first running state, the difference between the rotating speeds of the inner barrel and the impeller in the reverse rotation is not greater than the difference between the rotating speeds of the inner barrel and the impeller in the same rotation direction and at different speeds. So can form intensity comparatively suitable, comparatively stable rivers improve washing effect and clean rate.
