[0046] Embodiment one

[0047] As Figures 1 to 5 shown, the utility model provides a kind of clothes processing cylinder, can simplify the processing procedure of clothes processing cylinder, improve the production efficiency of clothes processing cylinder, reduce production cost.

[0048] Referring to Figure 1 , Figure 2 and Figure 3 , clothes processing cylinder includes cylinder 1, multiple inner recess structures 2 are arranged on the circumference of cylinder 1 at intervals, and multiple inner recess structures 2 are integrally formed with cylinder 1. Each inner recess structure 2 forms inner convex lifting rib 20 on the inner side of cylinder 1, and each inner recess structure 2 is surrounded to form flush cavity 201 on the outer side of cylinder 1. The inner wall of flush cavity 201 is provided with multiple first flush holes 202 that communicate flush cavity 201 and the inner cavity of cylinder 1, the axis of at least part of first flush hole 202 extends along the first direction, the axis of at least part of first flush hole 202 extends along the second direction, and the first direction and the second direction form an angle.

[0049] The laundry processing drum provided by the embodiment is integrally formed with the drum body 1 and the inner recess structure 2, that is, the drum body 1 and the lifting ribs 20 are integrally formed and processed, so that the connection between the lifting ribs 20 and the drum body 1 can avoid the problem of uneven connection, thereby preventing the clothes from being scratched, and ensuring that the laundry processing drum is more neat and beautiful in appearance, has good product consistency, and the connection between the lifting ribs 20 and the drum body 1 is reliable. Moreover, the integral forming processing method is simpler and has low processing difficulty, and the step of assembling the drum body 1 and the lifting ribs 20 can be omitted, thereby simplifying the processing procedure of the laundry processing drum, improving the production efficiency of the laundry processing drum, and reducing the production cost.

[0050] In addition, when the laundry processing drum rotates, the washing water can enter the flushing cavity 201 and be sprayed out to flush the clothes in the drum body 1 through the plurality of first flushing holes 202. Since the axes of a part of the first flushing holes 202 of the flushing cavity 201 extend in the first direction and the axes of another part of the first flushing holes 202 extend in the second direction, the washing water can be sprayed out at least from the two directions of the first direction and the second direction, thereby increasing the spraying coverage area of the washing water, and improving the flushing and washing effect on the clothes and the clothes processing effect of the clothes processing equipment.

[0051] Optionally, referring to Figure 3 The inner recess structure 2 includes the first plate segment 21, the second plate segment 22, and the third plate segment 23 connected in sequence and bent. One end of the first plate segment 21 away from the second plate segment 22 is connected with the drum body 1, and one end of the third plate segment 23 away from the second plate segment 22 is connected with the drum body 1. The first plate segment 21, the second plate segment 22, and the third plate segment 23 are all provided with the plurality of first flushing holes 202. The washing water entering the flushing cavity 201 can be sprayed out from the first flushing holes 202 on the first plate segment 21, the first flushing holes 202 on the second plate segment 22, and the first flushing holes 202 on the third plate segment 23, respectively, that is, the washing water can be sprayed toward the clothes in the drum body 1 from at least three directions, thereby expanding the spraying coverage area of the washing water and further improving the spraying and flushing effect.

[0052] In the embodiment, the first direction can be a direction perpendicular to the first plate segment 21 or the second plate segment 22, and the second direction can be a direction perpendicular to the second plate segment 22 or the third plate segment 23.

[0053] For example, the multiple first flushing holes 202 on the first plate segment 21, the second plate segment 22, and the third plate segment 23 are all arranged in an array. Specifically, the first plate segment 21 and the third plate segment 23 are each processed with two rows of first flushing holes 202, and the second plate segment 22 is processed with one row of first flushing holes 202. Each row includes multiple first flushing holes 202 arranged at intervals along the axial direction of the cylinder 1. In other embodiments, the arrangement and number of the first flushing holes 202 can be adapted and are not limited to the arrangement methods listed above. The first flushing holes 202 can be processed before forming the concave structure 2 or after forming the concave structure 2.

[0054] Optionally, the cross-sectional shape of the concave structure 2 is arched. This design makes the top surface of the lifting rib 20 an arc surface, which can prevent it from scratching clothing.

[0055] Specifically, such as Figure 2 and Figure 3 As shown, the first plate segment 21 and the third plate segment 23 are both flat plate segments, while the second plate segment 22 is an arc-shaped plate segment. Designing the first plate segment 21 and the third plate segment 23 as flat plate segments ensures the contact area between the lifting ribs 20 and the clothes, making it easier to lift the clothes, increasing the tumbling height of the clothes, and effectively dispersing the clothes to prevent them from tangling, thereby improving the washing effect of the clothes.

[0056] In other embodiments, the cross-sectional shape of the concave structure 2 can also be designed as a polygon. For example, a triangle (V-shape), rectangle, trapezoid, hexagon, etc., can be designed adaptively according to actual needs, and are not limited to the shapes listed above.

[0057] Optionally, the first plate segment 21, the second plate segment 22, and the third plate segment 23 are integrally formed with the cylinder body 1. Specifically, they can be integrally formed by sheet metal processing or bending processes. For example, the first plate segment 21, the second plate segment 22, and the third plate segment 23 can be pre-bent at a predetermined position on the tubular material of the garment processing tube, that is, the concave structure 2 can be formed, and then the entire tube body 1 can be wound. Alternatively, the first plate segment 21, the second plate segment 22, and the third plate segment 23 can be sequentially bent at a predetermined position during the winding process of the tube body 1, ultimately forming an integral tube body 1 and lifting ribs 20.

[0058] See Figure 3The first plate segment 21 is connected to the cylinder 1 through a first arc-shaped transition segment 211, and the third plate segment 23 is connected to the cylinder 1 through a second arc-shaped transition segment 231. In this way, stress concentration at the connection between the first plate segment 21 and the cylinder 1 can be avoided, and stress concentration at the connection between the third plate segment 23 and the cylinder 1 can also be avoided, thereby ensuring reliable connection between the inner recess structure 2 and the cylinder 1 and improving the anti-deformation capability of the lifting rib 20. In addition, the first arc-shaped transition segment 211 and the second arc-shaped transition segment 231 can reduce the contact resistance between the cylinder 1 and the washing water when the cylinder 1 rotates, thereby reducing the overall energy consumption of the laundry treatment apparatus.

[0059] Referring to Figure 2 The inner recess structure 2 extends along the axial direction of the cylinder 1, and the first water injection holes 202 are uniformly arranged on the inner recess structure 2 along the extension direction thereof. That is, the lifting rib 20 covers the axial direction of the cylinder 1, and washing water is sprayed in the axial direction of the cylinder 1 when the cylinder 1 rotates, thereby improving the spraying coverage area and the spraying uniformity and thus improving the laundry washing effect.

[0060] Exemplarily, three inner recess structures 2, i.e., three lifting ribs 20, are arranged on the cylinder 1 at intervals in the circumferential direction. In other embodiments, two, four or any other number of inner recess structures 2 can be arranged, and the number is not limited to the above-mentioned number.

[0061] In some optional embodiments, the extension direction of the inner recess structure 2 can intersect the axial direction of the cylinder 1. That is, the inner recess structure 2, i.e., the lifting rib 20, is arranged obliquely on the cylinder 1, and the requirements of lifting the laundry and spraying the washing water can also be met.

[0062] In other optional embodiments, the inner recess structure 2 can extend along the axial direction of the cylinder 1 in a curved manner. That is, the inner recess structure 2, i.e., the lifting rib 20, is in a curved structure, which can increase the contact area with the laundry and improve the effect of lifting the laundry. Exemplarily, the inner recess structure 2 extends in an S-shaped curved manner.

[0063] Referring to Figure 1 and Figure 2 The cylinder 1 is provided with a plurality of second water injection holes 11 in a preset region, and the second water injection holes 11 penetrate the cylinder wall of the cylinder 1. When the cylinder 1 rotates to the position where the second water injection holes 11 are submerged in the washing water, the washing water can enter the cylinder 1 from the plurality of second water injection holes 11 to wet the laundry. When the laundry treatment apparatus performs a dehydration program, the water in the laundry can be thrown out from the plurality of second water injection holes 11 and the plurality of first water injection holes 202 on the inner recess structure 2.

[0064] As the lifting ribs 20 extend along the axial direction of the cylinder 1 and the first water flushing holes 202 are arranged along the axial direction, the second water flushing holes 11 only need to be arranged in partial regions of the cylinder 1, i.e., the water inlet and water draining requirements of the cylinder 1 can be ensured, and the processing procedure can be further simplified. For example, a plurality of second water flushing holes 11 are arranged in the regions between two adjacent lifting ribs 20. The second water flushing holes 11 can be processed before the cylinder 1 is wound or can be processed after the cylinder 1 is wound.

[0065] Of course, in some embodiments, the second water flushing holes 11 can also be arranged in all regions of the cylinder 1 except the regions where the inner recess structures 2 are arranged.

[0066] Optionally, referring to Figure 1 and Figure 4 the laundry treating cylinder further comprises a front flange cover 3, a plurality of first grooves 31 are arranged on the front flange cover 3 in a circumferential direction, and the plurality of first grooves 31 correspond to the plurality of inner recess structures 2 one by one; the front flange cover 3 is riveted, welded or crimped to the first end of the cylinder 1. The plurality of first grooves 31 can make the front flange cover 3 closely fit the cylinder 1, and ensure the overall appearance of the laundry treating cylinder.

[0067] Further, the laundry treating cylinder further comprises a rear flange cover 4, a plurality of second grooves (not shown in the figure) are arranged on the rear flange cover 4 in a circumferential direction, and the plurality of second grooves correspond to the plurality of inner recess structures 2 one by one; the rear flange cover 4 is riveted, welded or crimped to the second end of the cylinder 1. The plurality of second grooves can make the rear flange cover 4 closely fit the cylinder 1, and ensure the overall appearance of the laundry treating cylinder.

[0068] In this embodiment, referring to Figure 5 a first flange is arranged on the front flange cover 3 in a circumferential direction, a second flange 41 is arranged on the rear flange cover 4 in a circumferential direction, and a third flange 12 is arranged on each end of the cylinder 1; when the cylinder 1 is assembled with the front flange cover 3 and the rear flange cover 4, the first flange 32 and the third flange 12 on one end of the cylinder 1 are engaged and pressed, and the second flange 41 and the third flange 12 on the other end of the cylinder 1 are engaged and pressed, so that the assembly is simple and the connection is firm.

[0069] In other embodiments, the cylinder 1, the front flange cover 3 and the rear flange cover 4 can also be fixed by welding or riveting.

[0070] Embodiment Two

[0071] This embodiment provides a laundry treating cylinder, which is different from the laundry treating cylinder of Embodiment One in that:

[0072] Referring to Figure 6The inner recess structure 2 comprises a first plate segment 21, a second plate segment 22 and a third plate segment 23 connected in sequence. The first plate segment 21 is connected to the cylinder body 1 at an end away from the second plate segment 22. The third plate segment 23 is connected to the cylinder body 1 at an end away from the second plate segment 22. The first plate segment 21, the second plate segment 22 and the third plate segment 23 are each provided with a plurality of first water flushing holes 202. The washing water entering the water flushing cavity 201 can be sprayed out of the first water flushing holes 202 on the first plate segment 21, the second plate segment 22 and the third plate segment 23 respectively, i.e., the washing water can be sprayed to the clothes in the cylinder body 1 from at least three directions, which expands the spraying coverage area of the washing water and further improves the spraying and flushing effect.

[0073] Further, the first plate segment 21, the second plate segment 22 and the third plate segment 23 are each an arc-shaped plate segment. The arc-shaped convex surface of the first plate segment 21 is opposite to the arc-shaped convex surface of the third plate segment 23. The arc-shaped convex surface of the second plate segment 22 faces the inner side of the cylinder body 1. That is, the two sides of the lifting rib 20 are concave inward. On the one hand, this can increase the contact area between the lifting rib 20 and the clothes, improve the lifting effect of the clothes, and thus achieve better washing effect. On the other hand, the curved surface contact can reduce the abrasion and damage to the clothes, and avoid damage to the clothes. In addition, the design of the concave surfaces on the two sides of the lifting rib 20 can make the washing water sprayed out of the plurality of first water flushing holes 202 more fine and uniform, and thus improve the washing efficiency and washing quality.

[0074] Embodiment three

[0075] The embodiment provides a clothes treatment cylinder, which is different from the clothes treatment cylinder of the embodiment one in that:

[0076] Optionally, the inner recess structure 2 has a first end and a second end arranged oppositely. The first end is closer to the inlet of the cylinder body 1 than the second end. The width of the inner recess structure 2 gradually decreases from the first end to the second end. The inlet of the cylinder body 1 corresponds to the feeding port on the front side of the clothes treatment device. The inner recess structure 2 (i.e., the lifting rib 20) is designed to have a gradually changing width, and the width of the front end (the first end) is large. During the rotation of the cylinder body 1, the lifting rib 20 can move the clothes to the rear of the cylinder body 1, so as to prevent the clothes from being stacked at the front end of the cylinder body 1. Thus, the clothes can be turned more fully, the clothes are prevented from being entangled, and the clothes treatment effect is improved.

[0077] Embodiment four

[0078] The embodiment provides a clothes treatment cylinder, which is different from the clothes treatment cylinder of the embodiment one in that:

[0079] Optionally, the tub 1 is integrally formed with a protruding structure protruding towards the inner side of the tub 1. That is, the protruding structure protruding towards the inner side of the tub 1 is arranged in the region between two adjacent lifting ribs 20 of the tub 1, which can further increase the friction effect on the clothes and improve the washing cleanliness and washing efficiency of the clothes.

[0080] The protruding structure can extend along the axial direction of the tub 1 to increase the contact area with the clothes. Of course, in some embodiments, the protruding structure can also be designed to extend along the circumferential direction of the tub 1. Alternatively, the protruding structure is designed to extend obliquely on the inner wall of the tub 1.

[0081] In some other embodiments, the protruding structure can be designed to include a plurality of frictional convexities arranged at intervals on the inner wall of the tub 1. That is, a plurality of frictional convexities are arranged on the inner wall of the tub 1 to enhance the friction and washing effect on the clothes and improve the washing efficiency of the clothes.

[0082] Example Five

[0083] The present embodiment provides a method for forming a clothes treatment drum, which is used to form the clothes treatment drum as described in any of the above embodiments. The method for forming the clothes treatment drum specifically includes the following steps:

[0084] The inner recess structure 2 is integrally formed at a predetermined position of the tub sheet, and the tub sheet with the inner recess structure 2 is wound to form the tub 1.

[0085] In the process of winding the tub 1, one side of the inner recess structure 2 and the connection between the tub 1 are bent to form a first arc-shaped transition section 211, and the other side of the inner recess structure 2 and the connection between the tub 1 are bent to form a second arc-shaped transition section 231.

[0086] By integrally forming the inner recess structure 2 at a predetermined position of the tub sheet in advance, the winding difficulty of the tub 1 can be reduced. For example, the inner recess structure 2 can be formed by sheet metal processing or edge folding processing. Using the method for forming the clothes treatment drum can not only ensure the processing quality of the clothes treatment drum, the product appearance and good consistency, but also can save the steps of assembling the tub 1 and the lifting rib 20, and simplify the processing procedure of the clothes treatment drum. Moreover, the integrated processing mode has a simpler process and lower processing difficulty, thereby improving the production efficiency of the clothes treatment drum and reducing the production cost.
