Background

With the continuous development of the washing machine technology, the washing machine tends to have large capacity, and the washing machine tends to have large capacity gradually, which inevitably results in the increase of the whole size of the washing machine, meanwhile, the water of the existing washing machine is distributed in the washing barrel and the outer barrel during washing, namely, water is distributed between the outer barrel and the washing barrel, the water consumption is large, and the waste of water resources is caused; dirt of an existing washing machine is easy to remain between an outer barrel and a washing barrel, bacteria are bred, water is distributed between the outer barrel and the washing barrel, the amount of detergent is large, resource waste of the detergent is caused, and cost saving is not facilitated.

Therefore, the related art proposes a washing machine using a washing tub as a water tub, and since the washing tub is used as a rotary tub, a drainage structure thereof is a key point of research and development, some manufacturers directly or indirectly drain water into an outer tub outside the washing tub by centrifugal water throwing; some manufacturers set a water outlet and a water discharge valve capable of controlling the opening and closing of the water outlet on the bottom wall of the washing tub, and discharge water to a water receiving device at the lower part by opening the water discharge valve, but the first centrifugal water throwing mode has higher requirements on the load of the motor, thereby greatly shortening the service life of the motor; the second type is stricter to the requirement of washing barrel stop rotating position, not only the production assembly precision is high, also high to the control accuracy requirement, the product qualification rate is lower.

Furthermore, since the washing tub is used as a rotary tub, the water in the washing tub cannot be directly heated, and the function of washing by heating the water is greatly limited, some manufacturers have made improvements to this drawback, and the water is heated and then introduced into the washing tub.

When the existing impeller type washing machine washes clothes, the space between an inner barrel (washing barrel) and an outer barrel (water barrel) is filled with water, the part of water between the inner barrel and the outer barrel is not used for washing, the water really used for washing is only the part in the inner barrel, so that the water resource waste is large, in addition, the excessive water between the inner barrel and the outer barrel can reduce the concentration of detergent/washing powder in washing liquid, many manufacturers improve the defects, and put forward a water-saving washing machine, namely, no small holes for water throwing are arranged on the barrel wall of the inner barrel, and the washing water and rinsing water are all concentrated in the inner barrel without holes, so that the inner barrel not only is a water-containing washing barrel, but also is a centrifugal dewatering barrel (also called as an inner barrel without holes). The outer barrel of the imporous water-saving washing machine is only a water receiving device which plays a role of collecting the imporous inner barrel and throwing water out during dehydration, the rotating speed of the inner barrel is improved during drainage, and water in the barrel rises along the wall of the inner barrel under the action of centrifugal force and is discharged from a water outlet below a balance ring at the upper part of the inner barrel; or the lower part of the inner barrel is provided with a controllable opening and closing water outlet, and most of water is discharged from the water outlet; during dehydration, the nonporous inner barrel rotates at high speed, residual water in clothes is upwards along the barrel wall of the nonporous inner barrel under the action of centrifugal force, is thrown out to an external outer barrel through a water outlet and is discharged through a water outlet and a water discharge pipe at the bottom of the outer barrel.
