Technical Field

[0001] This invention relates to the field of garment processing technology, and in particular to a garment processing tube, a garment processing tube forming method, and garment processing equipment. Background Technology

[0002] Washing machines, washer-dryer combos, and other garment processing equipment typically include an outer drum and an inner drum that rotates inside the outer drum. The inner drum is equipped with lifting ribs, which lift the clothes when the inner drum rotates, causing the clothes to fall from a height and be tumble to wash the clothes, ensuring a clean washing effect.

[0003] In existing technology, the inner drum of a washing machine and the lifting ribs are usually machined separately. The drum is formed by winding a sheet of tubing, and connecting holes are drilled at appropriate locations on the drum. Fasteners such as screws or bolts are passed through the connecting holes and connected to the lifting ribs to install the lifting ribs into the drum. This assembly method has two drawbacks. First, it can easily lead to unsightly joints, and uneven joints can easily scratch clothes. Second, the assembly process is cumbersome, time-consuming, labor-intensive, and inefficient.

In addition, because the concave structure forms a flushing cavity on the outside of the drum body corresponding to the position of the lifting rib, and a first water-blocking structure is provided on the first side of the flushing cavity and a second water-blocking structure is provided on the second side, when the garment processing drum rotates, the first water-blocking structure guides the washing water, which can force more washing water to gather into the flushing cavity, thereby causing more washing water to be sprayed out from the first flushing hole of the flushing cavity to wash the clothes in the drum body, improving the washing effect of the clothes. Meanwhile, the second water-blocking structure can prevent some of the washing water from temporarily remaining in the flushing chamber, allowing the washing water in the flushing chamber to rotate upwards with the drum. The washing water is then sprayed downwards onto the clothes inside the drum, improving the uniformity of the washing water spray. This ensures that the clothes inside the drum are thoroughly rinsed and soaked, further improving the washing effect of the clothes. In turn, this improves the clothes processing effect of the clothes processing equipment and enhances the user experience.

[0033] The garment processing tube forming method provided by this invention integrates the tube body with the concave structure, the first water-blocking structure and the second water-blocking structure through integral bending and forming. This method not only ensures the processing quality of the garment processing tube, resulting in an aesthetically pleasing and consistent product, but also eliminates the need for assembling the tube body and lifting ribs, simplifying the processing steps. Furthermore, the integral forming process is simpler and less difficult, thereby improving the production efficiency of the garment processing tube and reducing production costs.

[0055] Example 1

[0056] like Figures 1 to 7 As shown, this embodiment provides a garment processing tube that simplifies the processing steps and improves product production efficiency.

[0057] See Figure 1 , Figure 2 and Figure 3The garment processing drum includes a drum body 1. Multiple concave structures 2 are spaced circumferentially on the drum body 1, and are integrally formed with the drum body 1. Each concave structure 2 has an inwardly protruding lifting rib 20 on its inner side and forms a flushing cavity 201 on its outer side. Multiple first flushing holes 202 are provided on the concave structures 2, connecting the flushing cavity 201 and the inner cavity of the drum body 1. The water inlet of the flushing cavity 201 has a first side and a second side arranged opposite each other circumferentially on the drum body 1. A first water-blocking structure 3 is provided on the first side of the flushing cavity 201, guiding washing water into the flushing cavity 201. A second water-blocking structure 4 is provided on the second side of the flushing cavity 201, preventing at least a portion of the washing water from temporarily remaining inside the flushing cavity 201.

[0058] The garment processing tube provided in this embodiment, because the tube body 1 and the concave structure 2 are integrally formed, that is, the tube body 1 and the lifting rib 20 are integrally formed, avoid the problem of uneven connection at the connection between the lifting rib 20 and the tube body 1, thereby preventing scratches on the clothes. At the same time, it also ensures that the garment processing tube is neater and more aesthetically pleasing overall, and the connection between the lifting rib 20 and the tube body 1 is reliable. The integral forming process not only ensures the processing quality of the garment processing tube, but also eliminates the step of assembling the tube body 1 and the lifting rib 20, simplifying the processing procedure, improving the production efficiency of the garment processing tube, and reducing production costs.

[0059] Furthermore, since the concave structure 2 forms a flushing cavity 201 on the outside of the drum 1 corresponding to the position of the lifting rib 20, and a first water-blocking structure 3 is provided on the first side of the flushing cavity 201 and a second water-blocking structure 4 is provided on the second side, when the clothes handling drum rotates, the first water-blocking structure 3 guides the washing water, forcing more washing water to gather into the flushing cavity 201. Figure 4 The dotted arrow in the diagram indicates the direction of water collection, allowing more water to be sprayed out from the first flushing hole 202 of the flushing chamber 201 to rinse the clothes inside the drum 1, improving the washing effect. Simultaneously, the second water-blocking structure 4 prevents some washing water from temporarily remaining in the flushing chamber 201, causing the water in the flushing chamber 201 to rotate upwards with the drum 1. The water then sprays downwards onto the clothes inside the drum 1, improving the uniformity of water spray and ensuring the clothes inside the drum are thoroughly rinsed and soaked, further enhancing the washing effect. This, in turn, improves the overall garment processing efficiency of the garment processing equipment and enhances the user experience.

[0060] Optionally, see Figure 2 , Figure 3 and Figure 6The first water-blocking structure 3 extends away from the flushing chamber 201, and the plane containing the first water-blocking structure 3 is flush with the wall of the first side of the flushing chamber 201. The second water-blocking structure 4 extends along the tangent direction of the cylinder 1 towards the first water-blocking structure 3. Specifically, in conjunction with Figure 4 When the clothes handling drum rotates, the first water-blocking structure 3 prevents the washing water from flowing circumferentially along the drum body 1. Instead, it squeezes the washing water, forcing it into the flushing chamber 201. As the clothes handling drum rotates, the washing water that has entered the flushing chamber 201 is sprayed out from multiple first flushing holes 202 under inertia, and then sprayed onto the clothes inside the drum body 1. At the same time, some of the washing water that has entered the flushing chamber 201 can be blocked and temporarily stored in the flushing chamber 201 by the second water-blocking structure 4. When the flushing chamber 201 rotates with the drum body 1 to the area above the highest liquid level inside the drum body 1, the washing water is sprayed onto the clothes from the area above the highest liquid level, rinsing the clothes from all directions.

[0061] Designing the first water-blocking structure 3 flush with the wall of the first side of the flushing chamber 201 increases the contact area between the first water-blocking structure 3 and the washing water, forcing more washing water to gather into the flushing chamber 201, and also facilitates manufacturing. Designing the second water-blocking structure 4 to extend along the tangential direction of the drum 1 increases the space enclosed by the second water-blocking structure 4 within the flushing chamber 201, thereby preventing a sufficient amount of washing water from temporarily remaining within the flushing chamber 201, increasing the amount of washing water sprayed when the flushing chamber 201 rotates above the drum 1, and ensuring the washing effect on clothes.

[0062] In other embodiments, the first water-blocking structure 3 can be designed to be inclined toward the second water-blocking structure 4, or the first water-blocking structure 3 can be designed to extend radially along the cylinder 1, and the second water-blocking structure 4 can be inclined toward the interior of the flushing chamber 201. In this way, the first water-blocking structure 3 can guide the washing water into the flushing chamber 201, and the second water-blocking structure 4 can block some of the washing water and temporarily store it in the flushing chamber 201.

[0063] Optionally, the first water-blocking structure 3 is integrally formed with the cylinder 1 and the concave structure 2, and the second water-blocking structure 4 is integrally formed with the cylinder 1 and the concave structure 2. Integrating the cylinder 1 with the concave structure 2, the first water-blocking structure 3, and the second water-blocking structure 4 through integral bending and forming not only ensures the processing quality of the garment processing cylinder, resulting in an aesthetically pleasing and consistent product, but also eliminates the need to assemble the cylinder 1 and the lifting ribs 20, simplifying the processing steps, reducing processing difficulty, thereby improving the production efficiency of the garment processing cylinder and reducing production costs.

[0064] In this embodiment, the clothes processing drum can be used as the inner drum of a clothes processing device such as a washing machine or washer-dryer. The extension length of the first water-blocking structure 3 is less than the distance between the inner and outer drums of the clothes processing drum, and the extension length of the second water-blocking structure 4 is less than the width of the flushing chamber 201.

[0065] See Figure 4 The first water-blocking structure 3 includes a first extension section 31, a first bending section 32, and a second extension section 33 connected in sequence. The end of the first extension section 31 away from the first bending section 32 is connected to the concave structure 2, and the end of the second extension section 33 away from the first bending section 32 is connected to the cylinder 1. Both the first extension section 31 and the second extension section 33 extend in a direction away from the flushing chamber 201. That is, the first water-blocking structure 3 is bent and stacked between the cylinder 1 and the concave structure 2. While playing a water-blocking role, the first water-blocking structure 3 can also strengthen the connection strength between the cylinder 1 and the concave structure 2, prevent the concave structure 2 from deforming, and improve the deformation resistance of the lifting rib 20.

[0066] Continue reading Figure 4 The second water-blocking structure 4 includes a third extension section 41, a second bending section 42, and a fourth extension section 43 connected in sequence. The end of the third extension section 41 away from the second bending section 42 is connected to the concave structure 2, and the end of the fourth extension section 43 away from the second bending section 42 is connected to the cylinder 1. Both the third extension section 41 and the fourth extension section 43 extend towards the direction closer to the first water-blocking structure 3. The second water-blocking structure 4 is bent and stacked between the cylinder 1 and the concave structure 2. While serving as a water-blocking function, the second water-blocking structure 4 also strengthens the connection between the cylinder 1 and the concave structure 2, prevents deformation of the concave structure 2, and improves the deformation resistance of the lifting rib 20.

[0067] In this embodiment, the concave structure 2, the first extension section 31, the first bending section 32, the second extension section 33, and the cylinder 1 are integrally bent into shape. The concave structure 2, the third extension section 41, the second bending section 42, the fourth extension section 43, and the cylinder 1 are integrally bent into shape.

[0068] For example, the first water-blocking structure 3 and the second water-blocking structure 4 can be integrally bent using sheet metal processing or folding processes. Specifically, the inner concave structure 2 can be pre-bent at a predetermined position on the tubular material of the garment processing tube. Then, on the first side of the inner concave structure 2, a first extension segment 31, a first bent segment 32, and a second extension segment 33 are sequentially bent; on the second side of the inner concave structure 2, a third extension segment 41, a second bent segment 42, and a fourth extension segment 43 are sequentially bent. Finally, the tubular body 1 is wound to form the final product.

[0069] In other embodiments, after the cylinder 1 and the concave structure 2 are integrally formed, a first water-blocking structure 3 and a second water-blocking structure 4 can be separately provided on the first and second sides of the concave structure 2, respectively.

[0070] Optionally, see Figure 5 and Figure 6The first water-blocking structure 3 has a first arc-shaped chamfer 34 at its end, and the second water-blocking structure 4 has a second arc-shaped chamfer 44 at its end. The first arc-shaped chamfer 34 can reduce the contact resistance between the first water-blocking structure 3 and the washing water, and the second arc-shaped chamfer 44 can reduce the contact resistance between the second water-blocking structure 4 and the washing water, thereby reducing the rotational resistance of the drum 1 and reducing the overall energy consumption of the clothing processing equipment.

[0071] For example, the first arc-shaped chamfer 34 is processed at the connection between the first extension 31 and the first bending section 32 of the first water-blocking structure 3, and at the connection between the second extension 33 and the first bending section 32. The second arc-shaped chamfer 44 is processed at the connection between the third extension 41 and the second bending section 42 of the second water-blocking structure 4, and at the connection between the fourth extension 43 and the second bending section 42.

[0072] Optionally, the connection between the first water-blocking structure 3 and the cylinder 1 and / or the concave structure 2 is smoothly transitioned. Similarly, the connection between the second water-blocking structure 4 and the cylinder 1 and / or the concave structure 2 is also smoothly transitioned. This arrangement avoids stress concentration at the connection between the first water-blocking structure 3 and the cylinder 1 and / or the concave structure 2, as well as stress concentration at the connection between the second water-blocking structure 4 and the cylinder 1 and / or the concave structure 2, ensuring a reliable connection between the concave structure 2 and the cylinder 1.

[0073] 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.

[0074] Specifically, such as Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the concave structure 2 includes a first flat plate 21, an arc-shaped plate 22, and a second flat plate 23 connected in sequence. The end of the first flat plate 21 away from the arc-shaped plate 22 is connected to the cylinder 1 through a first water-blocking structure 3, and the end of the second flat plate 23 away from the arc-shaped plate 22 is connected to the cylinder 1 through a second water-blocking structure 4. Multiple first flushing holes 202 are provided on the first flat plate 21, the arc-shaped plate 22, and the second flat plate 23, and these holes are arranged in an array. When washing water enters the flushing chamber 201, the washing water can be sprayed out from the first flushing holes 202 on the first flat plate 21, the arc-shaped plate 22, and the second flat plate 23, respectively. That is, the washing water can be sprayed onto the clothes inside the cylinder 1 from at least three directions, expanding the coverage area of ​​the washing water spray and further improving the spray rinsing effect.

[0075] For example, both the first plate 21 and the second plate 23 are machined with two rows of first flushing holes 202, and the arc-shaped plate 22 is machined with one row of first flushing holes 202. Each row includes a plurality of first flushing holes 202 spaced apart 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 machined before forming the concave structure 2 or after forming the concave structure 2.

[0076] In other embodiments, the cross-sectional shape of the concave structure 2 can also be designed as a polygon. For example, a triangle, a trapezoid, etc., can be designed adaptively according to actual needs, and are not limited to the shapes listed above.

[0077] See Figure 2 The concave structure 2 extends along the axial direction of the drum body 1, and the concave structure 2 is provided with first flushing holes 202 along its extension direction. That is, the lifting ribs 20 cover the drum body 1 in the axial direction. When the drum body 1 rotates, washing water is sprayed out in the axial direction of the drum body 1, which improves the spray coverage area and spray uniformity, thereby improving the washing effect of clothes.

[0078] Furthermore, three concave structures 2 are provided at circumferential intervals on the cylinder 1, that is, three lifting ribs 20 are provided. In other embodiments, two, four or other equal numbers of concave structures 2 may also be provided, and the number is not limited to those listed above.

[0079] In some alternative implementations, the concave structure 2 can be designed such that its extension direction intersects the axial direction of the drum 1. That is, the concave structure 2 (i.e., the lifting rib 20) is inclinedly arranged on the drum 1, which can also meet the needs of lifting clothes and spraying washing water.

[0080] In some alternative embodiments, the concave structure 2 can be designed to extend in a curved manner along the axial direction of the cylinder 1. That is, the concave structure 2 (i.e., the lifting rib 20) is a curved structure, which can increase the contact area with clothing and improve the lifting effect of clothing. For example, the concave structure 2 extends in an S-shape.

[0081] See Figure 1 and Figure 2 The drum body 1 has multiple second flushing holes 11 within a preset area, and the second flushing holes 11 penetrate the drum wall of the drum body 1. When the drum body 1 rotates until the second flushing holes 11 are submerged in washing water, washing water can enter the drum body 1 through the multiple second flushing holes 11 to wet the clothes. When the clothes processing equipment performs the spin-drying program, the water in the clothes can be ejected from the multiple second flushing holes 11 and the multiple first flushing holes 202 on the concave structure 2.

[0082] Since the lifting ribs 20 extend along the axial direction of the cylinder 1 and the first flushing holes 202 are arranged along the entire length, the cylinder 1 only needs to have second flushing holes 11 in a local area to ensure the water inlet and dewatering requirements of the cylinder 1, which can further simplify the processing technology. For example, multiple second flushing holes 11 can be processed in a part of the area between two adjacent lifting ribs 20. The second flushing holes 11 can be processed before winding the cylinder 1 or after the cylinder 1 is wound and formed.

[0083] Of course, in some embodiments, the second flushing hole 11 can also be machined in all areas of the cylinder 1 except for the area where the concave structure 2 is located.

[0084] Optionally, see Figure 1 and Figure 7 The garment processing cylinder also includes a front flange cover 5, which has multiple first grooves 51 spaced circumferentially along its upper edge. Each of the first grooves 51 corresponds to a single concave structure 2. The front flange cover 5 is riveted, welded, or flanged and pressed to the first end of the cylinder body 1. The multiple first grooves 51 allow the front flange cover 5 to fit tightly with the cylinder body 1, ensuring the overall aesthetics of the garment processing cylinder.

[0085] Furthermore, the garment processing tube also includes a rear flange cover 6, which has multiple second grooves (not shown) spaced circumferentially along its upper edge. These second grooves correspond one-to-one with multiple recessed structures 2. The rear flange cover 6 is riveted, welded, or flanged and pressed to the second end of the tube body 1. The multiple second grooves ensure a tight fit between the rear flange cover 6 and the tube body 1, maintaining the overall aesthetic appeal of the garment processing tube.

[0086] In this embodiment, both the front flange cover 5 and the rear flange cover 6 are provided with flanges along the circumference. When assembling the cylinder 1 with the front flange cover 5 and the rear flange cover 6, it is only necessary to press and engage the flanges with the cylinder 1. The assembly is simple and the connection is reliable.

[0087] In other embodiments, the cylinder 1 can also be fixed to the front flange cover 5 and the rear flange cover 6 by welding or riveting.

[0088] Example 2

[0089] This embodiment provides a garment processing tube, which is a further improvement on the first embodiment. The main difference is:

[0090] Optionally, the drum body 1 is integrally formed with a protruding structure that protrudes towards the inside of the drum body 1. That is, by setting a protruding structure that protrudes towards the inside of the drum body 1 in the area between two adjacent lifting ribs 20, the friction on the clothes can be further increased, thereby improving the washing cleanliness and washing efficiency of the clothes.

[0091] The raised structure can extend axially along the tube body 1 to increase the contact area with clothing. Of course, in some embodiments, the raised structure can also be designed to extend circumferentially along the tube body 1. Alternatively, the raised structure can be designed to extend obliquely along the inner wall of the tube body 1.

[0092] Example 3

[0093] like Figure 8 As shown, this embodiment provides a method for forming a garment processing tube, used to form a garment processing tube as described in any of the above embodiments. The garment processing tube forming method includes the following steps:

[0094] The inner concave structure 2 is integrally bent at a predetermined position on the cylindrical sheet, and the cylindrical sheet with the inner concave structure 2 is wound into a cylindrical body 1.

[0095] During the winding and forming of the cylinder 1, the first water-blocking structure 3 is integrally bent on the first side of the concave structure 2, and the second water-blocking structure 4 is integrally bent on the second side of the concave structure 2.

[0096] By pre-forming the concave structure 2 at a predetermined position on the tubular material, the winding difficulty of the tubular body 1 can be reduced. For example, the concave structure 2 can be formed through sheet metal processing or folding processes. Using this method to process the garment processing tubing ensures high processing quality, aesthetic appeal, and good consistency. It also eliminates the need to assemble the tubular body 1 and the lifting ribs 20, simplifying the processing steps. Furthermore, the one-piece molding process is simpler and less difficult, thereby improving production efficiency and reducing production costs.

[0097] Example 4

[0098] This embodiment provides a method for forming a garment processing tube, which differs from Embodiment 3 in that:

[0099] like Figure 9 As shown, the garment processing tube forming method includes the following steps:

[0100] The tubular material is wound into a cylindrical body 1, and during the process of forming the cylindrical body 1, it is integrally bent at a preset position to form an inner concave structure 2.

[0101] During the winding and forming of the cylinder 1, the first water-blocking structure 3 is integrally bent on the first side of the concave structure 2, and the second water-blocking structure 4 is integrally bent on the second side of the concave structure 2.

[0102] By forming the concave structure 2 during the winding process of the cylinder 1, the forming quality of the concave structure 2 can be guaranteed, and deformation of the concave structure 2 can be avoided. Using this garment processing cylinder forming method ensures the processing quality of the garment processing cylinder, resulting in an aesthetically pleasing and consistent product. It also eliminates the need for assembling the cylinder 1 and the lifting ribs 20, simplifying the processing steps. Furthermore, the one-piece molding process is simpler and less difficult to manufacture, thereby improving the production efficiency of garment processing cylinders and reducing production costs.

[0103] Example 5

[0104] This embodiment provides a clothing processing device, including a device housing and a clothing processing drum as described in any of the above embodiments, the clothing processing drum being disposed within the device housing. The clothing processing device can be a washing machine, dryer, washer-dryer combo, etc. Taking a washing machine as an example, the clothing processing drum is the inner drum of the washing machine. The washing machine also includes an outer drum, and the clothing processing drum is rotatably arranged within the outer drum. Figure 1 As shown, a clothes processing chamber 10 is defined inside the clothes processing drum, and the clothes to be washed are placed inside the clothes processing chamber 10.

[0105] The garment processing device provided in this embodiment has a first water-blocking structure 3 on the first side and a second water-blocking structure 4 on the second side of the drum 1 in the flushing chamber 201. When the garment processing drum rotates, the first water-blocking structure 3 forces more washing water to converge into the flushing chamber 201, allowing more washing water to be sprayed out from the first flushing hole 202 to rinse the clothes inside the drum 1, thus improving the rinsing and washing effect. Simultaneously, the second water-blocking structure 4 allows the washing water in the flushing chamber 201 to rotate with the drum 1 to the area above the highest liquid level, spraying the clothes from top to bottom, improving the spray uniformity, further enhancing the washing effect, and ultimately improving the garment processing efficiency of the garment processing device, thus improving the user experience.

[0106] Furthermore, since the cylinder 1 is integrally bent and formed with the concave structure 2, the first water-blocking structure 3 and the second water-blocking structure 4, it can not only ensure the processing quality of the garment processing cylinder, resulting in a beautiful and consistent product, but also eliminate the need to assemble the cylinder 1 and the lifting rib 20, simplifying the processing procedures of the garment processing cylinder, reducing processing difficulty, improving the production efficiency of the garment processing cylinder, and reducing production costs.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
