[0002] Pulsator washing machines and other laundry processing equipment are household appliances that use electrical energy to generate mechanical action to dry clothes. As consumers' living standards improve, their requirements for laundry processing equipment are also getting higher and higher.

[0003] In related laundry processing devices, such as pulsator washing machines, the laundry processing device typically comprises a housing and an inner drum. The inner drum can be disposed within the housing. The inner drum can include a body and a bottom. The body and bottom can be fixedly connected together by bolts. The connection between the body and bottom forms a laundry processing chamber for placing laundry to be processed. During operation, the body and bottom rotate, thereby washing the laundry within the laundry processing chamber.

[0004] In existing laundry processing equipment, the use of screws to assemble the drum body and drum bottom makes the assembly process complicated, resulting in low installation efficiency and high labor costs. Furthermore, the use of screws to assemble the drum body and drum bottom causes significant vibration in the inner drum when the drum body and drum bottom rotate, resulting in loud operating noise.

[0005] The purpose of the present utility model is to provide a clothes processing device to optimize the structure of the clothes processing device in the related art to prevent misalignment between the drum body and the drum bottom, so as to improve the stability and accuracy of the connection between the drum body and the drum bottom.

[0006] The purpose of the present invention is not limited to the above-mentioned purpose, and those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] According to one aspect of the present invention, the present invention provides a clothing processing device, comprising: a casing, which is constructed as an outer shell of the clothing processing device; an inner drum, which is arranged in the casing; the inner drum includes a drum body and a drum bottom; the drum body is an annular cylindrical structure with openings at both ends, and the drum bottom is arranged at an opening at one end of the drum body; a first connecting rib extends outward from an edge of one side of the drum body close to the drum bottom; a second connecting rib extends outward around an edge of one side of the drum bottom close to the drum body; a limiting portion is convexly provided on the second connecting rib; the limiting portion is arranged on the outer side of the drum bottom; wherein the first connecting rib is connected to the second connecting rib, the first connecting rib is wrapped around the outer surface of the second connecting rib, the first connecting rib is wrapped around the outer surface of the limiting portion, and a limiting groove is formed at the limiting portion, and the limiting portion can be clamped in the limiting groove to prevent the first connecting rib and the second connecting rib from rotating relative to each other.

[0009] One of the above technical solutions has the following advantages or beneficial effects: when the first connecting rib is installed and connected to the second connecting rib, the first connecting rib can bend and deform and wrap around the outer surface of the second connecting rib. The first connecting rib can wrap around the outer surface of the limiting portion and form a limiting groove at the limiting portion. The limiting portion is engaged in the limiting groove to prevent the first and second connecting ribs from rotating relative to each other. Thus, the engagement and limiting of the limiting portion and the limiting groove can prevent the first and second connecting ribs from rotating relative to each other during subsequent docking. This can prevent misalignment between the cylinder body and the cylinder bottom, thereby improving the stability and accuracy of the connection between the cylinder body and the cylinder bottom.

[0011] One of the above technical solutions has the following advantages or beneficial effects: when the first connecting rib is bent and deformed and wrapped around the outer surface of the second connecting rib, a plurality of limiting grooves can be formed on the first connecting rib. The plurality of limiting grooves are arranged at intervals from each other. The plurality of limiting grooves and the plurality of limiting portions can be provided in a one-to-one correspondence. Thus, the plurality of limiting portions can be simultaneously positionally engaged in the plurality of limiting grooves. By engaging the plurality of limiting grooves with the plurality of limiting portions, the stability of the positional engagement between the first connecting rib and the second connecting rib can be improved, thereby preventing the first connecting rib and the second connecting rib from rotating relative to each other.

[0012] In some embodiments of the present application, the outward extending length of the first connecting rib is greater than the outward extending length of the second connecting rib.

[0013] One of the above technical solutions has the following advantages or beneficial effects: the length of the first connecting rib extending outward is greater than the length of the second connecting rib extending outward. Therefore, when the first connecting rib and the second connecting rib are connected to each other, the outer end of the first connecting rib can protrude from the outer end of the second connecting rib, and the part of the first connecting rib protruding from the second connecting rib can be bent and deformed and wrapped around the outer surface of the second connecting rib, thereby realizing a fixed connection between the cylinder body and the cylinder bottom.

[0014] In some embodiments of the present application, the limiting portion can protrude from the side wall surface of the second connecting rib away from the first connecting rib; the limiting groove can protrude from the side wall surface of the first connecting rib close to the second connecting rib.

The limiting groove can protrude from the side wall of the first connecting rib that is closer to the second connecting rib. Thus, when the first connecting rib and the second connecting rib are in contact, the limiting groove on the second connecting rib can be locked onto the first connecting rib, and the position between the limiting portion and the limiting groove can be more stable, preventing the first and second connecting ribs from rotating relative to each other.

[0016] In some embodiments of the present application, a groove is provided on the side wall of the second connecting rib away from the first connecting rib; the groove is annular and is arranged around the side wall of the second connecting rib away from the first connecting rib; the inner side of the groove is the outer peripheral side of the bottom of the cylinder, and the outer side of the groove is the peripheral edge of the second connecting rib; the limiting portion is formed by extending the bottom wall of the groove in the direction away from the first connecting rib; the limiting portion can protrude from the notch of the groove.

[0017] One of the above technical solutions has the following advantages or beneficial effects: the second connecting rib can be provided with a groove, which can be recessed on the side wall of the second connecting rib away from the second connecting rib. Thus, when the first connecting rib and the second connecting rib are in contact, the first connecting rib can bend and deform and wrap around the side wall of the groove. The position-limiting engagement between the first connecting rib and the groove can improve the connection stability between the first connecting rib and the second connecting rib, thereby improving the fixed connection between the cylinder body and the cylinder bottom.

[0023] One of the above technical solutions has the following advantages or beneficial effects: a connecting piece can be provided on the cylinder. The connecting piece can be protruded on the outer peripheral wall of the first connecting rib. Thus, when the first connecting rib and the second connecting rib are in contact with each other and the positioning protrusion is engaged in the positioning opening, the connecting piece can be arranged relative to the positioning notch, and then when the first connecting rib is bent and deformed and wrapped around the outer surface of the second connecting rib, the connecting piece can be embedded and engaged in the positioning notch, and then the first connecting rib and the second connecting rib can be positioned. In addition, by arranging the connecting piece relative to the positioning notch, when performing rotary riveting between the first connecting rib and the second connecting rib, the mutual rotation between the first connecting rib and the second connecting rib can be avoided, and thus the misalignment between the cylinder and the cylinder bottom can be prevented, thereby improving the stability and accuracy of the connection between the cylinder and the cylinder bottom.

[0025] One of the above technical solutions has the following advantages or beneficial effects: when the first connecting rib is wrapped around the outer surface of the second connecting rib, the embedded portion can be embedded in the positioning notch. Thus, by embedding the embedded portion in the positioning notch, the first and second connecting ribs can be positioned during docking. When riveting the first and second connecting ribs, the embedded portion can be pressed into the positioning notch and snapped into place, thereby preventing the first and second connecting ribs from rotating relative to each other.

[0026] In some embodiments of the present application, the connecting member is in the shape of an elongated strip, and the connecting member extends along the axial direction of the cylinder to the outer peripheral wall of the cylinder.

When the first connecting rib 211 is bent and deformed and wrapped around the outer surface of the second connecting rib 221, the clamping portion 2132 may be clamped in the clamping groove 224. By the mutual clamping between the clamping groove 224 and the clamping portion 2132, the first connecting rib 211 and the second connecting rib 221 can be prevented from rotating relative to each other, thereby preventing the cylinder body 21 and the cylinder bottom 22 from being misaligned during riveting, thereby improving the stability and accuracy of the connection between the cylinder body 21 and the cylinder bottom 22.

[0082] See also Figures 2 to 9As shown, in some embodiments, the second connecting rib 221 may be provided with a groove 226. The groove 226 may be recessed on the side wall of the second connecting rib 221 away from the second connecting rib 221. The groove 226 may be annular. The groove 226 may be arranged around the side wall of the second connecting rib 221 away from the first connecting rib 211. The inner side of the groove 226 may be the outer peripheral wall of the cylinder bottom 22. The outer side of the groove 226 may be the peripheral edge of the second connecting rib 221. The outer side of the groove 226 may be the inner peripheral wall of the convex rib 225. Thus, when the first connecting rib 211 and the second connecting rib 221 are in contact, the first connecting rib 211 can bend and deform and wrap around the groove side wall of the groove 226, thereby improving the connection stability between the first connecting rib 211 and the second connecting rib 221, and further improving the fixed connection between the cylinder body 21 and the cylinder bottom 22.

[0083] In some embodiments, a reinforcing rib 227 may be provided within the groove 226. One end of the reinforcing rib 227 may be connected to the inner sidewall of the groove 226, that is, one end of the reinforcing rib 227 may be connected to the outer periphery of the cylinder bottom 22. The other end of the reinforcing rib 227 may be connected to the outer sidewall of the groove 226, that is, the other end of the reinforcing rib may be connected to the peripheral edge of the second connecting rib 221. The reinforcing rib 227 can increase the strength of the groove 226 and prevent damage to the structure of the groove 226 during riveting between the cylinder body 21 and the cylinder bottom 22.

[0084] In some embodiments, multiple reinforcing ribs 227 may be provided. Multiple reinforcing ribs 227 may be spaced apart within the groove 226. Multiple reinforcing ribs 227 may be spaced apart and surround the groove 226. Multiple reinforcing ribs 227 can further enhance the strength of the groove 226, thereby preventing damage to the structure of the groove 226 during riveting of the barrel 21 and the barrel bottom 22.

[0086] See also Figures 2 to 10As shown, in some embodiments, a stopper 228 may be provided on the bottom 22. The stopper 228 may be located on the outside of the bottom 22. When the first connecting rib 211 and the second connecting rib 221 are in contact, the first connecting rib 211 may wrap around the outer surface of the second connecting rib 221. The first connecting rib 211 can wrap around the outer surface of the stopper 228. The first connecting rib 211 forms a stopper protrusion at the stopper 228. The stopper protrusion 214 can wrap around the outer surface of the stopper 228. A stopper groove is formed within the stopper protrusion 214. The stopper 228 can be engaged within the stopper groove, thereby preventing relative rotation between the first connecting rib 211 and the second connecting rib 221, and thereby preventing relative rotation between the body 21 and the bottom 22. This prevents misalignment between the body 21 and the bottom 22 during subsequent riveting between the first connecting rib 211 and the second connecting rib 221, thereby improving the stability and accuracy of the connection between the body 21 and the bottom 22.

[0087] In some embodiments, the limiting portion 228 can be protruded from the outer side wall of the second connecting rib 221 away from the cylinder body 21. Thus, when the first connecting rib 211 and the second connecting rib 221 are in contact with each other, the bottom edge of the first connecting rib 211 can be bent and deformed toward the inside of the cylinder bottom 22, so that the first connecting rib 211 can wrap around the outer surface of the second connecting rib 221, and the limiting protrusion can be locked with the limiting portion 228, thereby preventing the first connecting rib 211 and the second connecting rib 221 from rotating relative to each other.

[0088] It should be noted that, in some other embodiments, the limiting portion 228 may be protrudingly provided on the outer side wall of the second connecting rib 221 away from the center of the cylinder bottom 22 .

[0089] In some embodiments, multiple limiting portions 228 may be provided. Multiple limiting portions 228 may be spaced apart on the outer wall of the second connecting rib 221, away from the cylindrical body 21. When the first connecting rib 211 is bent and deformed and wrapped around the outer surface of the second connecting rib 221, multiple limiting protrusions 214 may be formed on the first connecting rib 211. The multiple limiting protrusions 214 are spaced apart from each other. Each of the multiple limiting protrusions 214 has a limiting groove formed therein. The multiple limiting grooves are spaced apart from each other. The multiple limiting protrusions 214 may correspond to the multiple limiting portions 228. The multiple limiting grooves may correspond to the multiple limiting portions 228. Thus, the multiple limiting portions 228 can be simultaneously locked in place within the multiple limiting grooves. The locking engagement of the multiple limiting portions 228 with the multiple limiting grooves improves the stability of the locking between the first connecting rib 211 and the second connecting rib 221, preventing relative rotation between the first and second connecting ribs 211 and 221.

[0090] In some embodiments, the limiting portion 228 and the positioning notch 223 can be spaced apart. The limiting portion 228 and the positioning notch 223 can be respectively provided at opposite ends of the cylinder bottom 22. The limiting portion 228 and the positioning notch 223 can be respectively provided at opposite ends of the second connecting rib 221, thereby improving the stability of the limiting between the first connecting rib 211 and the second connecting rib 221.

[0091] See also Figure 9 and Figure 10 As shown, in some embodiments, the limiting portion 228 can protrude from the side wall surface of the second connecting rib 221 away from the first connecting rib 211. The limiting groove can protrude from the side wall surface of the first connecting rib 211 close to the second connecting rib 221. Therefore, when the first connecting rib 211 and the second connecting rib 221 are in contact with each other, the limiting groove on the second connecting rib 211 can be locked on the first connecting rib 221, and the limiting between the limiting portion 228 and the limiting groove can be made more stable, preventing the first connecting rib 211 and the second connecting rib 221 from rotating relative to each other. In addition, when the first connecting rib 211 and the second connecting rib 221 are subsequently riveted, the cylinder body 21 and the cylinder bottom 22 can be prevented from being misaligned, thereby improving the stability and accuracy of the connection between the cylinder body 21 and the cylinder bottom 22.

[0092] In some embodiments, the limiting portion 228 can be formed by extending the bottom wall of the groove 226 in a direction away from the first connecting rib 211. The limiting portion 228 can protrude from the notch of the groove 226. The limiting portion 228 can protrude from the side of the rib 225 away from the second connecting rib 221, so that the limiting protrusion 214 can protrude from the side wall of the first connecting rib 211 near the second connecting rib 221. This further makes the limiting between the limiting portion 228 and the limiting protrusion 214 more stable, preventing the first connecting rib 211 and the second connecting rib 221 from rotating relative to each other. In addition, when the first connecting rib 211 and the second connecting rib 221 are subsequently riveted, the cylinder body 21 and the cylinder bottom 22 can be prevented from misalignment, thereby improving the stability and accuracy of the connection between the cylinder body 21 and the cylinder bottom 22.
