Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular, relates to a washing inner barrel and a washing machine. Background Art

[0002] The existing pulsator type washing machine and agitator type washing machine all install a barrel with a bottom and holes in a cylindrical container, and the same is true for the drum type washing machine.

[0003] A pulsator-type washing machine has a pulsator installed at the bottom of the barrel, and a stirring impeller is installed in the barrel of a stirring-type washing machine. The pulsator or the stirring impeller is used to stir the clothes to wash them, but the speed is slow and the clothes are easily tangled.

[0004] The inner drum of the drum washing machine is provided with lifting ribs, which are used to lift the clothes to a certain height and then drop them, so that the clothes are thrown onto the inner drum wall, and the clothes are washed by throwing them. The lifting ribs provided in the inner drum are provided with two lifting surfaces, which are respectively suitable for throwing the clothes when the inner drum rotates forward and reversely.

[0005] In the prior art, the structures of the two lifting surfaces of the lifting ribs are basically the same, and the beating force and friction degree of the clothes cannot be adjusted according to user needs, nor can the number of times the clothes are turned over be increased. In addition, the falling force of the clothes is small and the cleaning power is weak. For precious clothes, it is very easy to cause serious wear of the clothes during washing, and for clothes with serious dirtiness, there is a problem of poor washing effect. In addition, the rotation speed of the drum must be slow, otherwise the clothes will stick to the wall of the drum under the action of centrifugal force and cannot fall down, and the clothes cannot be stirred to achieve the purpose of cleaning.

[0006] The Chinese patent with publication number CN104313832A discloses an inner barrel of a washing machine, including an inner barrel body, characterized in that the inner barrel body includes an inner barrel interior and an inner barrel outer wall, washing particles are arranged between the inner barrel inner wall and the inner barrel outer wall, a plurality of mountain-shaped protrusions are evenly distributed around the inner barrel inner wall, a plurality of pearl-shaped protrusions are arranged on the inner barrel inner wall between the mountain protrusions, the bottom of the inner barrel inner wall is in a pulsator shape, a central column is arranged in the center, and an anti-corrosion film is arranged on the inner barrel inner wall. The inner barrel inner wall of the washing machine provided by this invention is provided with mountain-shaped protrusions around the inner wall, and pearl-shaped protrusions are arranged between the mountain protrusions. Although a better rubbing effect on clothes is achieved and the washing time is reduced, the mountain-shaped protrusions and pearl-shaped protrusions cannot drive the clothes to turn over. When washing, the clothes are easily attached to the inner wall of the inner barrel, which reduces the washing effect.

[0007] A Chinese patent with publication number CN110258077A discloses an inner drum of a drum washing machine, comprising an inner drum body, lifting ribs arranged on the inner wall of the inner drum body and having two lifting surfaces, one of the lifting surfaces being provided with a rolling assembly for reducing the friction coefficient of the lifting surface and being rotatable relative to the lifting ribs, the rolling assembly comprising a ball rotatably arranged in each rolling groove on one side of the lifting rib and forming a first lifting surface with the lifting rib, the ball in the rolling assembly being spherical with a smooth surface, reducing the friction coefficient with the clothes, but failing to effectively drive the clothes to flip, thereby reducing the washing effect.

[0008] In view of this, the present invention is proposed. Summary of the invention
