Problems solved by technology

However, during the dehydration process, the inner barrel rotates at a high speed, and the water flow cannot all flow upward along the vertical grooves arranged on the side wall of the barrel body, and the drainage efficiency is not high.

Embodiment 1

[0040] As shown in the figure, the convex and concave pressure type 2 of the side wall of the inner bucket body described in this embodiment extends in an arc shape from the lowermost end 8 to the uppermost end 7 to one side. The convex and concave pressure type 2 extends rightward and upward from the lowermost end 8 to the uppermost end 7, and the center of the arc-shaped bend is located at the obliquely lower or obliquely upper portion of the arc-shaped bend. Or it can also extend to the uppermost end 7 upwards to the left.

[0041] One of the convex peaks 3 and the valley 4 adjacent to it on one side extend gradually from the lowermost end 8 with a distance until they intersect at one point at the uppermost end, and the convex peak 3 and the valley 4 adjacent to it on the other side There is a distance from the lowermost end to the intersection point, and there is a distance to the uppermost end. At the uppermost end, the concave valley 4 intersects with the convex peak 3 a...

Embodiment 2

[0044] As shown in the figure, the convex and concave pressure type 2 of the side wall of the inner barrel body 1 of the present invention extends in an arc shape from the lowermost end 8 to the uppermost end 7 to one side. The convex and concave pressure type 2 extends rightward and upward from the lowermost end 8 to the uppermost end 7, and the center of the arc-shaped bend is located at the obliquely lower or obliquely upper portion of the arc-shaped bend. Or it can also extend to the uppermost end 7 upwards to the left.

[0045] One of the convex peaks 3 and the valley 4 adjacent to it on one side extend gradually from the lowermost end 8 with a certain distance, until the uppermost end 7 intersects at one point, the convex peak 3 and the valley adjacent to it on the other side 4. From the lowermost end, the point of intersection extends gradually away from each other, and there is a distance to the uppermost end, and to the uppermost end 7, the concave valley intersects w...

Embodiment 3

[0048] As shown in the figure, the convex and concave pressure type of the side wall of the inner barrel body 1 of the present invention extend in an arc from the lowermost end 8 to the middle part 9 to one side, and the convex and concave pressure types extend from the middle part 9 to the uppermost end. 7 is curved and extended to the other side, and the two arcs are smoothly transitioned in the middle. The centers of the two sections of arc-shaped bending are respectively located on different sides of the arc-shaped bending.

[0049] The convex peaks 3 of the convex and concave pressure type 2 are convex ribs with a smooth transition, and the two sides of the convex ribs respectively extend smoothly and gradually to the valleys 4 .

[0050] One of the convex peaks 3 and the valley 4 adjacent to it on one side extend gradually from the lowermost end 8 with a certain distance, until the uppermost end 7 intersects at one point, the convex peak 3 and the valley adjacent to it o...

Abstract

The invention relates to a washing machine inner drum and a washing machine. The sidewall of a drum body of the inner drum is provided with multiple convex and concave profiling parts. The concave and convex profiling parts bend and extend in an axial direction. The surface of each concave and convex profiling part is smooth and gradually changes. The concave and convex profiling parts are sequentially arranged to cross each other in a circumferential direction. Smooth transition is conducted in a connecting place of every two adjacent concave and convex profiling parts. During spinning and draining, water bends and extends along concave pits of the concave and convex profiling parts on the sidewall of the drum body of the inner drum so as to be drained quickly. In this way, the draining speed is increased and the washing time is saved. During washing, the concave and convex profiling parts on the sidewall of the drum body of the inner drum enable the water to flow in many directions, and the clothes cleaning efficiency is improved when water and clothes bump and strike each other. Meanwhile, the concave and convex surfaces rub against the clothes in many directions, so the clothes cleaning efficiency is increased. During washing, the clothes come into contact with the concave and convex profiling parts, and the concave and convex profiling parts guide the clothes to make the clothes roll over to a greater extent, so the clothes cleaning efficiency is further increased.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to an inner tub of a washing machine and a washing machine. Background technique [0002] Due to the existing pulsator-type washing machine, when doing laundry, the space between the inner tub and the side wall of the outer tub needs to be filled with water, and this part of water between the inner and outer tubs does not participate in washing, and the water that really participates in washing is only the water in the inner tub. Partly, this causes a large waste of water resources. In addition, too much water between the inner and outer tubs will also reduce the concentration of detergent / washing powder in the washing liquid. [0003] Many manufacturers have made improvements to the above-mentioned defects and introduced a water-saving washing machine, that is, there is no small hole for water leakage on the side wall of the inner tub, and all the washing and rinsing water is concen...
