The best is as follows: H1/H is more than or equal to 0.55 and is less than or equal to 0.65, at the moment, even the water content is higher in the load, dehydration speed is very big, because delivery port 31 is located the darker distance in water receiving tank 2, and delivery port 31 also has sufficient distance with water receiving tank diapire 22, delivery port 31 goes out water and hardly sputters the water receiving tank 2 outside, simultaneously water storage in the water receiving tank 2 also hardly exceeds the position of delivery port 31, can avoid washing bucket 1 to rotate and drive water guide channel 3 and stir the water storage in the water receiving tank 2 and take place to the condition of outside, the influence of water storage to delivery port 31 water outlet speed has also been avoided.
