The working time of the clothes machine improves the washing efficiency.

In addition, since the water leakage hole 104 is provided on the peripheral wall of the bottom of the washing tub 31, the dehydration effect of the washing machine 100 can be improved, that is, the problem of local dehydration can be improved.

In the traditional washing machine, there are many dehydration holes in the pattern of the inner barrel, and the number of dehydration holes is between 160 and 3000. Therefore, in the washing machine, the washing barrel with dehydration holes in the pattern area is washed, and the water level between the inner and outer barrels is Consistent. However, in the washing process, only the water in the washing tub is used for washing, and the water level in the inner and outer barrels is uniform, so that there is a large amount of washing water between the inner and outer barrels, which causes a large waste. In the present invention, since there are no dewatering holes in the pattern of the washing tub, and even in some embodiments of the present invention, there are water leakage holes 104, and the number of the water leakage holes 104 is between 24 and 40, preferably 28, far less than the dewatering hole in the center of the traditional washing tub, so when washing, the inner bucket water level is higher than the outer bucket water level, which plays a very good dynamic water saving effect.

Other configurations and operations of the washing machine in accordance with embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.
