[0001] The present invention belongs to the technical field of laundry equipment, and particularly relates to a lifting rib and a washing machine having the same. Background Art

[0002] With the continuous improvement of people's living standards, washing machines have become essential household appliances. The barrel body of the washing tub of the existing pulsator washing machine is set perpendicular to the ground. During the washing process, the pulsator arranged at the bottom of the washing tub rotates forward or backward to drive the water flow movement, and then drives the clothes to flip, so that friction is generated between the clothes and between the clothes and the barrel wall for washing; in addition, the lifting rib is one of the main components of the inner tub of the drum washing machine. Its main function is to generate a frictional rubbing effect on the clothes when the drum washing machine washes clothes, and on the other hand, drive the clothes to rotate together. The clothes are lifted out of the liquid level and sent to a certain height, and then fall back into the washing water under the action of gravity, thereby generating a rod-beating and falling effect to achieve the washing effect.

[0003] The lifting ribs of conventional washing machines are all of equal height or have a single-sided slope. In order to achieve a better beating effect, the height of the lifting ribs is generally relatively high, and the overall occupied volume is relatively large, which limits the volume of the inner tub, the overall dimensions of the machine, etc. Summary of the Invention

[0039] Preferably, the left side surface 213 and the right side surface 214 of the convex part 2 are integrally inclined towards the top surface 211 of the convex part 2, so that the width gradually decreases from the bottom surface of the convex part 2 to the top surface 211. On the one hand, it ensures the strength of the lifting rib itself, so that the amount of clothing lifted by the lifting rib increases. On the other hand, it ensures a reliable connection between the lifting rib and the inner wall of the washing tub 4.

[0040] Preferably, the left side surface 213 and the right side surface 214 of the convex part 2 are inclined surfaces and / or arc surfaces, and both are provided with first water flow holes 215; the first water flow holes 215 communicate with the inner cavity 11 of the lifting rib and are arranged along the trend of the surface where they are located; when washing clothes, a part of the washing water can enter the inner cavity 11 of the lifting rib through the first water flow holes 215 and enter the outer cylinder through the holes on the inner wall of the washing tub 4, and a part of the washing water can be guided by the left side surface 213 or the right side surface 214 to the concave part 3, increasing the flushing effect of the washing water.

[0041] Preferably, the convex part 2 includes a first convex part 21 and a second convex part 22. The first convex part 21 and the second convex part 22 both have a top surface 211, an end surface 212, a left side surface 213 and a right side surface 214, and are respectively arranged at the front and rear ends of the lifting rib. The height of the first convex part 21 is different from that of the second convex part 22; specifically, the first convex part 21 is arranged at the front end of the lifting rib, and the second convex part 22 is arranged at the rear end of the lifting rib; the height of the second convex part 22 is less than or equal to the height of the first convex part 21; when washing clothes, the amount of clothes lifted by the first convex part 21 is greater than the amount of clothes lifted by the second convex part 22. The washing water and clothes at the first convex part 21 can be guided to the second convex part 22. Since the second convex part 22 is close to the bottom of the washing tub 4, the washing water generates complex movements, further increasing the flushing effect on the clothes.

[0042] Preferably, the concave part 3 is arranged between the first convex part 21 and the second convex part 22. A first transition surface 31 is formed between the concave part 3 and the top surface of the first convex part 21, and a second transition surface 32 is formed between the concave part 3 and the top surface of the second convex part 22, so that the top surfaces of the first convex part 21 and the second convex part 22 can be smoothly transitioned to the concave part 3; the washing water at the first convex part 21 and the second convex part 22 can be guided to the concave part 3.

[0043] It should be noted that the number and positions of the convex parts and concave parts of the present invention are not limited. Multiple convex parts and concave parts can be provided according to needs. For example, two concave parts are respectively arranged on both sides of the lifting rib, and one convex part is arranged in the middle of the lifting rib. The convex part lifts the clothes, and the friction ribs of the concave part contact and rub the clothes for washing, increasing the washing effect of the lifting rib.

[0045] Preferably, the bottom surface of the concave part 3 is a plane or an arc surface concave towards the bottom of the lifting rib 1 or an arc surface convex towards the direction away from the bottom of the lifting rib 1.

Thus, for the lifting rib provided in this embodiment, on the one hand, the convex part 2 can be used to lift the clothes to a high place, and the friction ribs 341 of the concave part 3 contact and rub against the clothes, having a certain washing effect. On the other hand, the convex part 2 is used to guide the washing water to the concave part 3, making the washing water produce a greater flushing effect and increasing the washing effect.

[0048] Preferably, the inner cavity 11 of the lifting rib is provided with fixing columns 12, which cooperate with the mounting holes 41 on the washing tub 4 for fixing the lifting rib; the bottom 1 of the lifting rib is provided with buckles 13, which cooperate with the card slots 42 on the washing tub 4 for positioning the lifting rib.

[0049] Preferably, the inner cavity 11 of the lifting rib is further provided with reinforcing ribs 14, which extend along the left - right direction of the lifting rib and a plurality of them are arranged along the front - back direction of the lifting rib, for strengthening the strength of the lifting rib and ensuring that the lifting rib can lift a certain amount of clothes.

[0050] As Figure 2cAs shown in the figure, this embodiment provides a lifting rib, where the heights B of the first convex part 21 and the second convex part 22 are B≥15 mm, and the linear length A of the bottom surface 34 of the concave part needs to meet the condition: 1 / 3 of the length of the lifting rib ≤ A ≤ 4 / 5 of the length of the lifting rib; the inclination angles C of the first transition surface 31 and the second transition surface 32 meet the condition: 80° ≤ C ≤ 25°; the height of the friction rib 341 on the bottom surface of the concave part protruding from the bottom surface of the concave part is 0.5 mm - 4 mm.

[0053] The lifting rib realizes the functions of lifting and cleaning clothes in the following way: when the washing machine washes clothes, the first convex part 21 and the second convex part 22 lift the clothes, and a part of the washing water can enter the inner cavity 11 of the lifting rib from the first flow hole 215 and the second flow hole 33, and a part of the water flow can be guided to the concave part 3 to reduce the pressure of the lifting rib on lifting the clothes; the height of the second convex part 22 is less than or equal to the height of the first convex part 21, and a part of the washing water enters the bottom of the washing tub 4, so that the washing water increases the flushing effect on the clothes during the contact process with the convex part 2, the concave part 3 and the bottom of the washing tub 4 of the lifting rib; during the process of the clothes being lifted, they contact and rub against the friction rib 341 of the concave part 3, having a certain washing effect.
