Further, the water guide surface is a plane.

Further, the water guide surface is a curved surface; the curved water guide surface is connected with the outer wall of the inner barrel main body, so that the opening forms a drain hole.

Furthermore, the projection of the water guide surface on the outer wall of the inner barrel main body is in a semi-elliptical shape, a triangular shape or a rectangular shape.

Further, the shape of the drainage hole is arc-shaped or polygonal.

Furthermore, the inner side of the edge of the water guide surface is subjected to fillet treatment.

A washing machine is provided, which comprises the washing machine inner barrel.

Compared with the prior art, the application has the advantages and positive effects that: in the washing machine inner barrel and the washing machine, the inclined water guide surface is arranged on the lateral side of the dewatering hole of the outer wall of the washing machine inner barrel body and is positioned above the dewatering hole, the opening formed between the inclined water guide surface and the inner barrel body faces the back of the dewatering rotation direction of the inner barrel body, when the washing machine inner barrel rotates to dewater, water in washing matters is thrown out through the dewatering hole of the inner barrel body under the action of centrifugal force, the flow direction is changed under the guide of the inclined water guide surface, and the water is sprayed out from the opening of the guide surface, so that the outer wall of the inner barrel body is washed, the residual dirt on the outer wall of the inner barrel is avoided, the technical problem that the residual dirt on the outer wall of the inner barrel of the existing washing machine is easy is solved, and the possibility of bacterial; simultaneously, because the slope of water guide surface sets up, its opening is towards the dorsad of interior bucket main part dehydration direction of rotation for interior bucket main part is at rotatory in-process, and the guide surface outside also plays the reposition of redundant personnel effect to the air, can reduce the striking in air and dehydration hole, reduces the air noise, and reduces air resistance, promotes the work efficiency who improves the motor.

Other features and advantages of the present application will become more apparent from the detailed description of the embodiments of the present application when taken in conjunction with the accompanying drawings.

Detailed Description

The following describes embodiments of the present application in further detail with reference to the accompanying drawings.

As shown in fig. 2 (partially schematic in the drawing), the inner tub of the washing machine provided by the present application includes an inner tub main body 21, a dewatering hole 22 is formed on the inner tub main body 21, an inclined water guide surface 23 is provided on an outer wall of the inner tub main body 21 at the side of the dewatering hole 22, the water guide surface 23 is located above the dewatering hole 22, and an opening (a shown in fig. 3) formed between the water guide surface 22 and the inner tub main body 21 faces away from a dewatering rotation direction (arrow x shown in fig. 2 and 3) of the inner tub main body 21.

As shown in fig. 3, when the inner tub of the washing machine is rotated to perform dewatering, water in the laundry is thrown out through the dewatering holes 22 of the inner tub body 21 by centrifugal force, changes the flow direction by the guidance of the inclined water guide surface 23, and is sprayed out from the opening a of the guide surface 23, so that the outer wall of the inner tub body 21 is washed, the residual dirt on the outer wall 21 of the inner tub is avoided, and the problem that the residual dirt on the outer wall of the inner tub of the existing washing machine is easy is solved, and the possibility of bacterial growth is reduced.

Meanwhile, because the water guide surface 23 is obliquely arranged, the opening a of the water guide surface faces the back of the dehydration rotation direction of the inner barrel main body, the outer side of the guide surface 23 also has a shunting effect on air in the rotation process of the inner barrel main body 21, the impact of the air and the dehydration holes 22 can be reduced, the air noise is reduced, and the noise in dehydration is reduced; meanwhile, the air resistance is reduced, and the working efficiency of the motor is improved.

As shown in fig. 4, the water guiding surface 23 is a curved surface, and the curved water guiding surface 23 is connected with the outer wall of the inner barrel body 21 so that the opening forms a water discharging hole 24; the curved water guide surface is connected with the outer wall of the inner barrel body, so that a semi-closed water guide channel is formed between the water guide surface and the inner barrel body, and water thrown out from the dewatering holes is sprayed to the outer wall of the inner barrel body from the water discharge holes 24 through the guide of the semi-closed water guide channel, namely the guide of the inclined inner wall of the water guide surface, so that the outer wall of the inner barrel body is washed. The specific curved surface form of the water guide surface is not limited in the application, the projection of the water guide surface on the outer wall of the inner barrel main body can be in a semi-elliptical shape, a triangular shape or a rectangular shape, the projection of the curved surface on the outer wall of the inner barrel main body shown in fig. 4 is in a triangular shape, the projection of the curved surface on the outer wall of the inner barrel main body shown in fig. 5 is in a semi-elliptical shape or the like, the shape of the water drain hole formed between the water guide surface and the inner barrel main body can be in an arc shape or a polygonal.
