The inner wall of the inner cylinder body is provided with lifting ribs, the lifting ribs are connected with the inner wall of the inner cylinder body and extend from front to back, and the area of the outer contour of the lifting ribs is gradually reduced along the direction from front to back.

In the process of rotating the inner cylinder body, the lifting rib can lift clothes to a high position, then the clothes fall under the action of gravity to form upper and lower beating, and the washing process of the clothes is completed. Under the action of centrifugal force, the clothes can approach the lifting ribs, and the area of the outer contour of the lifting ribs 10 is gradually reduced along the front-to-back direction, so that the clothes can move from front to back, and the effect of loading is achieved; the clothes not only can do circumferential movement along with the rotation of the inner cylinder body, but also can move along the axial direction of the inner cylinder body, so that the mutual entanglement of the clothes is avoided, and the clothes treatment effect is improved. If the clothes are accumulated at the front end of the inner cylinder, a pushing force is generated to the door body of the clothes treating apparatus, so that the door body is deformed, the washing effect is also affected, and the lifting ribs 10 are arranged, so that the clothes move backwards and are far away from the door body.

Specifically, can set up the card protruding on promoting the muscle, set up the draw-in groove on the interior barrel, when aligning card protruding and draw-in groove, make card protruding and draw-in groove joint through pressing the promotion muscle.

The outer surface of the lifting rib is provided with a front end face 101, a rear end face 102, a first side face 103 and a second side face 104 which are arranged between the front end face 101 and the rear end face 102, the area of the front end face 101 is larger than that of the rear end face 102, and the first side face 103 and the second side face 104 are smooth curved surfaces. It will be appreciated that the connection between the first side 103 and the front face 101, between the first side 103 and the rear face 102, between the second side 104 and the front face 101, and between the second side 104 and the rear face 102 is smooth.

Specifically, the front end face 101 has a height greater than that of the rear end face 102. It can be understood that the bottom of lifting rib is connected with the inner cylinder, and the direction of height of lifting rib is on a parallel with the radial direction of inner cylinder, and the height of preceding terminal surface 101 is greater than the height of rear end surface 102 for the clothing can be from preceding back removal, reaches the effect of receiving the load. In fig. 6, the height of the front end surface 101 is denoted by H1. In fig. 7, the height of the rear end surface 102 is denoted by H2.

In this embodiment, the height H1 of the front end face 101 is 40mm to 50mm.

The bottom width of the front end face 101 is larger than that of the rear end face 102, and the effect of load collection is further achieved. In fig. 4, the bottom width of the front end surface 101 is denoted by L1, and in this embodiment, L1 is 50mm to 80mm. In fig. 4, the bottom width of the rear end surface 102 is denoted by L2, and in this embodiment, the area ratio of the front end surface 101 to the rear end surface 102 is equal to or greaterEnsuring better load receiving effect.

In the present embodiment, the front end face 101 and the rear end face 102 are inclined faces, and the front end face 101 extends obliquely in a direction approaching the rear end face 102 along the bottom end to the top end of the front end face 101; along the bottom end to the top end of the rear end surface 102, the rear end surface 102 extends obliquely in a direction approaching the front end surface 101. That is, the tip end of the front end face 101 and the tip end of the rear end face 102 are close to each other as shown in fig. 6 and 7. The front end face 101 is obliquely arranged, so that the clothes can be guided, and the clothes can be moved backwards. The rear end face 102 is obliquely arranged, so that the rear end face 102 is matched with the front end face 101, clothes are folded towards the middle, the clothes are contacted with the lifting ribs, and the clothes are prevented from being stuck to the inner wall of the inner cylinder body.

Along from front to back direction, promote muscle tortuous extension, also can reach the effect of receipts load. Specifically, the extending shape of the lifting rib may be streamline, so that the washing water and the flow are smoother, and the sliding of the laundry is smoother.

Both the first side 103 and the second side 104 are water-facing surfaces, the other being water-facing surfaces, i.e. surfaces which are facing forward against the pressure of the water during rotation of the inner barrel. The inclination of the upstream surface is smaller than that of the downstream surface, that is, the gradient of the upstream surface is slower, the gradient of the downstream surface is steeper, and thus the area of the upstream surface is larger, and more water can be collected.

The inside cavity that promotes the muscle forms water storage chamber 106, is provided with a plurality of water hole 107 on the promotion muscle, and water hole 107 communicates with water storage chamber 106. In the process of rotation of the inner barrel, the lifting rib can rotate from the lower position to the higher position along with the inner barrel, water enters the water storage cavity 106 from the water passing hole 107, when the lifting rib reaches the higher position, the water flows down from the water passing hole 107, and water flow impacts clothes, so that the washing effect is improved.

At least a portion of the first side 103 and/or the second side 104 is a steepest descent curve surface that extends from front to back. The curve surface of the steepest descent line is arranged based on the steepest descent line principle, so that the fluid speed can be increased, the water flow is increased from front to back, and then clothes move from front to back along with the water flow, and the effect of collecting load is achieved. The area of the outer contour of the lifting rib is gradually reduced and matched with the fastest descent line curved surface, so that clothes can rapidly move from front to back, and the load collecting effect is improved.

The curve surface of the steepest descent line is a curve surface obtained by extending a contour line along a set path, and the contour line is the curve of the steepest descent line. According to the principle of the steepest descent, as shown in fig. 10, O, A is provided as two fixed points which are different in height and not on the same vertical line, and if friction and air resistance are not counted, a particle m falls from the point O to the point a (p, q) along a curve under the action of gravity, and the time required for sliding down along the steepest descent line is shortest, so that the curved surface of the steepest descent line has the fastest water flow speed.

The set path is a curve extending from the top end to the bottom end of the lifting rib. That is, while ensuring that the first side 103 and the second side 104 are curved surfaces, a portion of the first side 103 is a steepest descent line curved surface and a portion of the second side 104 is a steepest descent line curved surface in the front-to-rear direction.

Specifically, the front half portion of the first side 103 may be provided as a steepest descent line curved surface such that the laundry is gathered to the middle portion of the lifting rib. Similarly, the front half of the second side 104 is configured as a steepest descent line curved surface, so that the laundry is gathered toward the middle of the inner drum.

As shown in fig. 4, an intersection point between the bottom end of the first side 103 and the bottom end of the front end surface 101 is defined as a point C, an intersection point between the bottom end of the first side 103 and the bottom end of the rear end surface 102 is defined as a point D, and a line connecting the point C and the point D in the front-rear direction is a maximum-speed descent curve, that is, the point C is a vertex of the maximum-speed descent curve, and the point D is an end point of the maximum-speed descent curve.

In this embodiment, the outer surface of the lifting rib further has a top end surface 105, and the top end surface 105 extends between the front end surface 101 and the rear end surface 102, and along the direction from the top end surface 105 to the bottom end of the lifting rib, the area of the outer contour of the lifting rib gradually increases, so that the lifting rib has a structure with a small top and a large bottom. Therefore, the lifting rib can be guaranteed to have certain strength to lift clothes, and the connection between the lifting rib and the inner cylinder body is more reliable.

In this embodiment, the first side 103 is an upstream surface, and the second side 104 is a downstream surface. A plurality of water passing holes 107 are distributed on the first side surface 103 and the top end surface 105. In the process of rotation of the inner cylinder body, the lifting rib can rotate from the lower position to the higher position along with the inner cylinder body, water enters the water storage cavity 106 from the water passing holes 107, when the lifting rib reaches the higher position, the water flows down from the water passing holes 107 on the top end face 105, water flow impacts clothes, a spraying effect is achieved, and a washing effect is improved.

The water holes 107 distributed on the first side 103 are distributed into a plurality of rows, and the water holes 107 in two adjacent rows are arranged at intervals, that is, each water hole 107 in one row is opposite to the gap between two water holes 107 in the other row, so that the area is fully utilized.

The number of water passing holes 107 formed in the top end surface 105 is smaller than the number of water passing holes 107 formed in the first side surface 103. In the process that the inner cylinder rotates from low to high, more water passing holes 107 are convenient for water to rapidly fill the water storage cavity 106, when the lifting ribs reach the high, water flows down from the water passing holes 107 on the top end face 105, and the water passing holes 107 can improve the water flow speed, so that water can impact clothes with larger force, and the washing effect is improved.

The shape of the water passing hole 107 may be a circle, a polygon or an elongated shape, and different shapes have different spraying effects. The strip-shaped water passing holes 107 have larger water passing area, and the washing effect is improved.

A plurality of lifting ribs can be arranged in each inner cylinder at intervals, and the upstream surface is positioned at the front side of the back surface along the rotation direction of the inner cylinder. The inner cylinder body can rotate positively or reversely. Therefore, the first side 103 may be set as the water-facing surface, or the second side 104 may be set as the water-facing surface, so that the corresponding lifting ribs play a role in both clockwise rotation and counterclockwise rotation of the inner cylinder, thereby improving the washing efficiency and the washing effect. Specifically, M+N lifting ribs are arranged in the inner cylinder at intervals, when the inner cylinder rotates clockwise, the water facing surfaces of the M lifting ribs face water, and when the inner cylinder rotates anticlockwise, the water facing surfaces of the N lifting ribs face water.

In the embodiment, the lifting rib is of a split structure, so that the lifting rib is convenient to mount and dismount. Specifically, the lifting rib comprises a lifting rib body 11 and a cover plate 12, the top of the lifting rib body 11 is provided with a mounting opening 111, and the cover plate 12 is detachably connected with the mounting opening 111. The front end face 101, the rear end face 102, the first side face 103 and the second side face 104 are all located on the lifter body 11, and the top end face 105 is located on the cover plate 12.

The water passing holes 107 formed in the cover plate 12 and the water passing holes 107 formed in the lifting rib body 11 can be the same or different in shape. By replacing the cover plate 12, different shapes of water passing holes 107 can be used to achieve different spraying effects.

The bottom surface of the cover plate 12 is embedded in the mounting opening 111, and the top surface of the cover plate 12 is higher than the top surface of the lifting rib body 11. It will be appreciated that the top of the cover 12 is rounded to avoid scratching the clothing. Specifically, the top surface of the cover plate 12 may be about 1mm higher than the top surface of the lifter body 11.

The cover plate 12 and the lifting rib body 11 can be clamped. Specifically, a locking protrusion may be provided on the cover plate 12, and a locking groove may be provided on the lifting rib body 11, and the locking protrusion is locked with the locking groove when the cover plate 12 is pressed into the mounting opening 111.
