Description

Technical Field

[0001] Some embodiments of the present application relate to washing equipment technology, and more particularly to a washing machine. Background Art

[0002] A pulsator washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes.

[0003] A pulsator washing machine typically consists of a housing and a drum assembly. The drum assembly is located within the housing, forming a washing chamber for washing clothes. Pulsator washing machines also have multiple suspension rods. Multiple mounting brackets are welded to the top of the housing to mate with the suspension rods. The suspension rods are connected to the mounting brackets and the drum assembly, respectively, to suspend the drum assembly within the housing.

[0004] However, the corners are connected to the housing by welding, which results in high production costs for the pulsator washing machine. Utility Model Content

[0005] The purpose of this application is to at least solve the above-mentioned problems.

[0006] Some embodiments of the present application provide a washing machine, comprising:

[0007] A chassis, wherein the top of the chassis has a loading port; the chassis comprises:

[0008] Box;

[0009] A structural member is provided on the box body, and the structural member partially overlaps with the box body, and the box body and the structural member are respectively provided with connection holes at the overlapping portions;

[0010] a barrel assembly disposed in the housing, the barrel assembly having a washing chamber, a barrel opening of the barrel assembly facing the introduction port, and the barrel opening of the barrel assembly communicating with the washing chamber;

[0011] A door cover is rotatably connected to the top of the chassis;

[0012] The rivet has a penetration portion and a first clamping portion, at least a portion of the penetration portion is penetrated through the connecting holes of the box body and the structural member; the first clamping portion is arranged around the periphery of the penetration portion, at least a portion of the first clamping portion is abutted against a side of the structural member facing away from the box body; a second clamping portion is formed circumferentially around the penetration portion, at least a portion of the second clamping portion is abutted against a side wall of the box body facing away from the structural member.

[0013] The washing machine provided in the embodiment of the present application has a portion of the penetration portion of the rivet component penetrated into the connecting hole between the case and the structural member. By pulling the rivet component with a rivet gun, a second clamping portion can be formed around the circumference of the penetration portion, so that at least a portion of the first clamping portion can be abutted against the side of the structural member facing away from the case, and at least a portion of the second clamping portion can be abutted against the side wall of the case facing away from the structural member, so that the case and the structural member are connected by rivets. Compared with welding, the rivet connection does not require complex equipment, thereby reducing the production cost of the washing machine.

[0014] It should be noted that welding connection requires a welding machine, welding wire, gas supply system and protective equipment, etc. Riveting connection only requires a rivet gun.

[0015] In some embodiments of the present application, a force-applying member is further included, wherein the force-applying member includes a rod body and a rod head connected to each other, the penetration portion is a penetration tube, the rod body is partially located in the penetration tube, and the rod head is located at one end of the penetration tube away from the first clamping portion, and the rod head is configured to move toward the penetration tube and enter the penetration tube so that the penetration tube portion forms the second clamping portion.

[0016] The above technical solution has the following advantages or beneficial effects: when the box body and the structural member are connected, part of the penetration tube of the rivet member is penetrated through the connecting hole of the box body and the structural member, the first clamping part abuts against the structural member, part of the rod body of the force-applying member is located in the penetration tube, and the rod head is located at the end of the penetration tube away from the first clamping part. The rod body drives the rod head to move, so that the rod head can move toward the penetration tube and enter the penetration tube. Under the extrusion action of the rod head, the penetration tube partially forms the second clamping part, which can enable the box body and the structural member to be connected by rivets. Compared with the welding method, the rivet connection does not require complicated equipment, thereby reducing the production cost of the washing machine.

[0017] In some embodiments of the present application, the overlapping portion of the structural member and the box body is located on a side of the box body facing the first clamping portion.

[0018] The above technical solution has the following advantages or beneficial effects: the penetration portion of the rivet can penetrate the connection hole of the structural member and the connection hole of the box in sequence, and the first clamping portion abuts against the structural member.

[0019] In some embodiments of the present application, the difference between the diameter of the connection hole on the structural member and the diameter of the connection hole on the box body is greater than 0.5 mm and less than 1 mm.

[0020] The above technical solution has the following advantages or beneficial effects: if the difference between the diameter of the connection hole on the structural member and the diameter of the connection hole on the box is less than 0.5mm, due to the deviation between the axis of the connection hole on the structural member and the axis of the connection hole on the box, the penetration portion of the rivet is not easy to penetrate the connection hole of the structural member and the connection hole of the box, so the installation efficiency of the box and the structural member is reduced. If the difference between the diameter of the connection hole on the structural member and the diameter of the connection hole on the box is greater than 1mm, the first clamping portion of the rivet is located inside the connection hole on the structural member, which will cause the first clamping portion of the rivet to be unable to clamp the structural member, so that the box and the structural member cannot be connected together. Therefore, by making the difference between the diameter of the connection hole on the structural member and the diameter of the connection hole on the box greater than 0.5mm and less than 1mm, the penetration portion of the rivet can be easily penetrated into the connection hole of the structural member and the connection hole of the box, and at the same time, the first clamping portion of the rivet can clamp the structural member, so that the box and the structural member can be riveted together.

[0021] In some embodiments of the present application, the box body and the structural member are respectively provided with at least two connecting holes in the overlapping portion, and the rivet is correspondingly provided in each connecting hole.

[0022] The above technical solution has the following advantages or beneficial effects: the box body and the structural member are connected by at least two rivets, which can improve the connection strength between the box body and the structural member and improve the stability between the box body and the structural member.

[0023] In some embodiments of the present application, at least two of the connection holes of the structural member are arranged at intervals.

[0024] The above technical solution has the following advantages or beneficial effects: interference between at least two riveted parts corresponding to the structural part is avoided.

[0025] In some embodiments of the present application, the distance between two adjacent rivets is less than 28 mm.

[0026] The above technical solution has the following advantages or beneficial effects: If the spacing between two adjacent rivets is greater than 28 mm, the connection strength between the rivets and the housing and the structural components will be weak, which will make the rivets easily fall off the housing and the structural components when the washing machine is dropped or vibrated during transportation. By making the spacing between two adjacent rivets less than 28 mm, the connection strength between the rivets and the housing and the structural components can be increased, so that the rivets are less likely to fall off the housing and the structural components when the washing machine is dropped or vibrated during transportation.

[0027] In some embodiments of the present application, the structural member includes a corner, and the corner is located on the top of the box;

[0028] A suspension rod is provided in the box body, the top of the suspension rod is connected to the mounting angle, and the bottom of the suspension rod is connected to the cylinder assembly.

[0029] The above technical solution has the following advantages or beneficial effects: the corner and the flange at the top of the box are connected by riveting parts, so compared with the welding method, the corner and the box are connected by riveting, which does not require complicated equipment and can reduce the production cost of the washing machine.

[0030] In some embodiments of the present application, at least one water leakage hole is provided on the building angle, and the water leakage hole passes through the building angle in a direction from the top of the box body toward the bottom of the box body.

[0031] The above technical solution has the following advantages or beneficial effects: by setting a leakage hole on the corner, water on the corner can leak to the base of the chassis, preventing water from flowing to the electrical components around the corner, so that the washing machine can work normally.

[0032] In some embodiments of the present application, the chassis further includes an upper connecting plate and a lower connecting plate, wherein the upper connecting plate and the lower connecting plate are located in the housing, the upper connecting plate is connected to the housing on both sides in the width direction of the washing machine, and the lower connecting plate is connected to the housing on both sides in the width direction of the washing machine;

[0033] The structural member includes at least one of the upper connecting plate and the lower connecting plate.

[0034] The above technical solution has the following advantages or beneficial effects: The upper connecting plate is connected to the rear side of the housing by riveting. The lower connecting plate is also connected to the rear side of the housing by riveting. Compared to welding, this arrangement uses riveting to connect both the upper connecting plate and the housing, eliminating the need for complex equipment and reducing the production cost of the washing machine.

[0078] The following will be combined with the drawings in some embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only some of the embodiments of the present application, not all of them. All other embodiments obtained by ordinary technicians in this field based on some embodiments of the present application without making any creative efforts shall fall within the scope of protection of this application.

[0079] Some embodiments of the present application provide a washing machine, which may include a pulsator washing machine, a drum washing machine, and other washing equipment capable of washing clothes and objects. Figure 1 To the attached Figure 4 The washing machine is shown as a pulsator washing machine, and the structure of the washing machine is further explained.

[0080] The depth of the washing machine is the X-axis. The width of the washing machine is the Y-axis. The height of the washing machine is the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0081] The side of the washing machine in the +X-axis direction is the front side of the washing machine. The side of the washing machine in the -X-axis direction is the rear side of the washing machine. The side of the washing machine in the +Y-axis direction is the left side of the washing machine. The side of the washing machine in the -Y-axis direction is the right side of the washing machine. The side of the washing machine in the +Z-axis direction is the top side of the washing machine. The side of the washing machine in the -Z-axis direction is the bottom side of the washing machine.

[0082] The washing machine includes a cabinet 10 .

[0083] The chassis 10 includes a housing 11. The side of the housing 11 in the +Z axis direction is the top of the housing 11. The side of the housing 11 in the -Z axis direction is the bottom of the housing 11.

[0084] In some examples, along the width direction of the washing machine, that is, along the Y-axis direction, the housing 11 has two first walls 111 oppositely disposed (see Figures 11 to 14 shown).

[0085] Along the depth direction of the washing machine, that is, along the X-axis direction, the housing 11 has two second walls 112 that are opposite to each other.

[0086] Along the circumference of the washing machine, an arc-shaped corner 113 is connected between the second wall 112 and the first wall 111. Such an arrangement can make a smooth transition between the second wall 112 and the first wall 111.

[0087] Exemplarily, the material forming the box body 11 is bent by a bending machine, so that an arc angle 113 can be formed between the second wall 112 and the first wall 111 .

[0088] The cabinet 10 includes a frame 12. The frame 12 can be provided on the cabinet body 11. The frame 12 can have a loading port. The loading port is used to load clothes.

[0089] In some examples, the frame 12 is disposed around the top of the box body 11. For example, the frame 12 can be snap-fitted to the box body 11 and fixed by screws.

[0090] The chassis 10 includes a base 16. The base 16 is disposed at the bottom of the box body 11. The base 16 is used to support the box body 11.

[0091] Exemplarily, the base 16 and the box body 11 are fixed by screws.

[0092] In some embodiments, see Figure 5 As shown, the washing machine may further include a drum assembly 201. The drum assembly 201 is arranged in the housing 11. The drum assembly 201 has a washing chamber. The barrel opening of the drum assembly 201 is communicated with the washing chamber and faces the loading port so that the clothes loaded through the loading port can enter the washing chamber for washing.

[0093] The barrel assembly 201 may include an outer barrel 202. The outer barrel 202 is disposed in the box body 11, and the barrel opening of the outer barrel faces the injection port.

[0094] The drum assembly 201 may include an inner drum 200. The inner drum 200 is rotatably disposed within the outer drum 202, with the opening of the inner drum 200 also facing the loading port. The opening of the inner drum 200 communicates with the washing chamber, thereby connecting the opening of the drum assembly 201 with the washing chamber. The inner drum has a washing chamber. During the laundry washing process, the inner drum can rotate relative to the outer drum to clean the laundry in the washing chamber.

[0095] The inner tub 200 has a plurality of communication holes on its wall. The communication holes are used to connect the washing chamber with the interior of the outer tub 202 so that the liquid in the washing chamber can flow into the outer tub 202 through the communication holes and be discharged from the outer tub 202 after washing.

[0096] It should be noted that the height direction of the inner cylinder 200 is Figure 1 The Z direction is consistent.

[0097] In some embodiments, the washing machine may further include a door cover 40. The door cover 40 is rotatably connected to the chassis 10. The door cover 40 can open or close the loading port when rotating relative to the chassis 10.

[0098] For example, a door cover 40 is provided at the top of the cabinet 10 and can open or close the loading port. When the door cover 40 opens the loading port, it is convenient for the user to load clothes into the loading port. When the door cover 40 closes the loading port, it can cover the loading port to enhance the safety of the washing machine during operation.

[0099] In some examples, the chassis 10 may include a structural member. The structural member may be provided on the housing 11. The structural member may partially overlap with the housing 11, and the housing 11 and the structural member may each be provided with a connection hole in the overlapping portion.

[0100] The washing machine may include a rivet 400 (see 6 and 7). The rivet 400 may have a penetration portion 403 and a first clamping portion 401. Figure 6 A portion of the rivet 400 is shown in FIG.

[0101] At least a portion of the penetration portion 403 may be penetrated through the connection hole of the box body 11 and the connection hole of the structural member.

[0102] The first clamping portion 401 is disposed around the circumference of the penetration portion 403 and is located on the side of the structural member facing away from the box body 11. At least a portion of the first clamping portion 401 abuts against the side of the structural member facing away from the box body 11.

[0103] A second clamping portion 402 is formed around the circumference of the penetration portion 403. At least a portion of the second clamping portion 402 abuts against a side wall of the box body 11 facing away from the structural member.

[0104] For example, at least a portion of the penetration portion 403 is configured to undergo plastic deformation under an external force to form a second clamping portion 402, such that at least a portion of the second clamping portion 402 abuts against a side wall of the housing 11 facing away from the structural member, and at least a portion of the first clamping portion 401 abuts against a side of the structural member facing away from the housing 11. With this arrangement, when a rivet gun is used to pull the rivet, at least a portion of the penetration portion 403 undergoes plastic deformation to form the second clamping portion 402, enabling a riveted connection between the housing 11 and the structural member. Compared to welding, riveted connections do not require complex equipment, thereby reducing the production cost of the washing machine.

[0105] It should be noted that welding connection requires a welding machine, welding wire, gas supply system and protective equipment, etc. Riveting connection only requires a rivet gun.

[0106] In some examples, the first clamping portion 401 may be a first clamping plate, and the second clamping portion 402 may be a second clamping plate.

[0107] In some embodiments, the washing machine may further include a force applying member 500 (see Figure 8 The force applying member 500 includes a rod body 501 and a rod head 502 connected to each other.

[0108] The penetrating portion 403 may be a penetrating tube. The rod body 501 of the force-applying member 500 may be partially located within the penetrating tube and partially located outside the penetrating tube. The rod head 502 is located at the end of the penetrating tube facing away from the first clamping portion 401. The rod head 502 is configured to move toward the penetrating tube and enter the penetrating tube, causing the penetrating tube portion to form the second clamping portion 402. With such arrangement, when the housing 11 and the structural member are connected, part of the penetration tube of the rivet member 400 is penetrated through the connecting hole of the housing 11 and the structural member, the first clamping portion 401 abuts against the structural member, part of the rod body 501 of the force-applying member 500 is located in the penetration tube, and the rod head 502 is located at the end of the penetration tube away from the first clamping portion 401. The rod body 501 drives the rod head 502 to move, so that the rod head 502 can move toward the penetration tube and enter the penetration tube. Under the extrusion action of the rod head 502, the penetration tube is partially plastically deformed to form the second clamping portion 402, so that the housing 11 and the structural member can be connected by riveting. Compared with the welding method, the riveting connection does not require complicated equipment, thereby reducing the production cost of the washing machine.

[0109] For example, when connecting the box body 11 and the structural member, the portion of the penetration tube of the rivet member 400 is inserted into the connection hole between the box body 11 and the structural member, the portion of the rod body 501 of the force-applying member 500 is located within the penetration tube, and the rod head 502 is located at the end of the penetration tube away from the first clamping portion 401. The portion of the rod body 501 of the force-applying member 500 located outside the penetration tube is inserted into the chuck of the rivet gun, the rivet gun abuts the first clamping portion 401, and the first clamping portion 401 abuts the structural member. The rivet gun drives the rod body 501 of the force-applying member 500 to move, and the rod body 501 drives the rod head 502 to move, so that the rod head 502 can move toward the penetration tube and enter the penetration tube. Under the squeezing action of the rod head 502, the penetration tube is partially plastically deformed to form the second clamping portion 402. After the second clamping portion 402 is formed, the rivet gun can remove the portion of the rod body 501 located outside the penetration tube.

[0110] In other embodiments, the washing machine may not include the force-applying member 500. The penetration portion 403 may be a threaded tube. When the housing 11 and the structural member are connected, the threaded tube portion of the rivet member 400 is penetrated through the connection hole between the housing 11 and the structural member. The screw of the rivet nut gun is inserted into the threaded tube, the rivet nut gun abuts against the first clamping portion 401, and the first clamping portion 401 abuts against the structural member. The rivet nut gun rotates the screw, which generates tension on the threaded tube, and a portion of the threaded tube is squeezed and plastically deformed to form the second clamping portion 402.

[0111] In some embodiments, see Figure 5 As shown, the washing machine includes a mounting angle 600. The mounting angle 600 is located at the top of the housing 11. In the height direction of the washing machine, the mounting angle 600 is located below the surrounding frame 12.

[0112] Exemplarily, the structural member includes a corner 600. The top of the box body 11 is provided with a flange 114. The flange 114 is located inside the box body 11. The corner 600 partially overlaps with the flange 114 on the top of the box body 11.

[0113] See also Figures 6 to 8 As shown, the corner 600 and the flange 114 at the top of the box body 11 are connected by riveting through the rivet 400. Compared with the welding method, the corner 600 and the box body 11 are connected by riveting, which does not require complicated equipment and can reduce the production cost of the washing machine.

[0114] The washing machine includes a hanging rod. The top of the hanging rod is connected to the mounting angle 600, and the bottom of the hanging rod is connected to the drum assembly 201. Exemplarily, the washing machine includes multiple hanging rods and multiple mounting angles 600, and each hanging rod corresponds to a mounting angle 600.

[0115] See also Figure 9As shown, a mounting hole 601 is provided on the stand angle 600, and the top of the suspension rod is connected to the mounting hole 601 of the stand angle 600. A connecting seat is provided on the cylinder assembly 201, and the bottom of the suspension rod is connected to the connecting seat.

[0116] For some examples, see Figure 9 As shown, at least one water leakage hole 602 is provided on the corner 600 .

[0117] A water leakage hole 602 extends through the corner 600 from the top of the housing 11 toward the bottom of the housing 11, i.e., along the -Z axis. The water leakage hole 602 is provided on the corner 600 so that water on the corner 600 can leak onto the base 16 of the chassis 10, preventing water from flowing into the electrical components around the corner 600, thereby allowing the washing machine to operate normally.

[0118] For example, the diameter of the water leakage hole 602 gradually decreases from the top of the box body 11 to the bottom of the box body 11, that is, along the -Z axis. This configuration can help guide the water on the corner 600 so that the water on the corner 600 can flow into the water leakage hole 602.

[0119] In some examples, the shear strength of the corner 600 can be greater than or equal to 1728 MPa. For example, the shear strength of the corner 600 can be 1728 MPa, 1730 MPa, 1732 MPa, 1735 MPa, 1738 MPa, or 1740 MPa. Of course, the shear strength can also be other values, and those skilled in the art can choose according to their needs, and this embodiment does not limit this. If the shear strength of the corner 600 is less than 1728 MPa, it will cause the rivet 400 to easily fall off from the box 11 and the corner 600 when the washing machine is dropped, impacted by an oblique surface, or vibrated during transportation, and the corner 600 will tear. By ensuring that the shear strength of the corner 600 is greater than or equal to 1728 MPa, it can prevent the rivet 400 from falling off from the box 11 and the corner 600 when the washing machine is dropped, impacted by an oblique surface, or vibrated during transportation, and prevent the corner 600 from tearing.

[0120] The tensile strength of the corner 600 can be greater than or equal to 672 MPa. For example, the tensile strength of the corner 600 can be 672 MPa, 674 MPa, 676 MPa, 678 MPa, 680 MPa, 690 MPa, or 800 MPa. Of course, the tensile strength can also be other values, and those skilled in the art can select them according to their needs. This embodiment does not limit this. If the tensile strength of the corner 600 is less than 672 MPa, it will cause the rivet 400 to easily fall off from the box 11 and the corner 600 when the washing machine is dropped, impacted by an oblique surface, or vibrated during transportation, and the corner 600 will tear. By ensuring that the tensile strength of the corner 600 is greater than or equal to 672 MPa, it can be prevented from easily falling off from the box 11 and the corner 600 when the washing machine is dropped, impacted by an oblique surface, or vibrated during transportation, and the corner 600 can be prevented from tearing.

[0121] In some embodiments, the overlapping portion of the structural member and the box body 11 is located on the side of the box body 11 facing the first clamping portion 401. This arrangement allows the penetration portion 403 of the rivet 400 to penetrate the connection hole of the structural member and the connection hole of the box body 11 in sequence, and the first clamping portion 401 abuts against the structural member.

[0122] For example, see Figure 7 and Figure 8 As shown, the overlapping portion of the corner 600 and the box body 11 is located on the side of the box body 11 facing the first clamping portion 401 .

[0123] In some examples, the difference between the diameter of the connecting hole on the structural member and the diameter of the connecting hole on the box body 11 is greater than or equal to 0.5 mm and less than or equal to 1 mm. For example, the difference between the diameter of the connecting hole on the structural member and the diameter of the connecting hole on the box body 11 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 0.95 mm or 1 mm, etc. Of course, the difference can also be other values, and those skilled in the art can choose according to needs, and this embodiment is not limited to this. It should be understood that if the difference between the diameter of the connecting hole on the structural member and the diameter of the connecting hole on the box body 11 is less than 0.5 mm, due to the deviation between the axis of the connecting hole on the structural member and the axis of the connecting hole on the box body 11, the penetration portion 403 of the rivet 400 is not easy to penetrate the connecting hole of the structural member and the connecting hole of the box body 11, so that the installation efficiency of the box body 11 and the structural member is reduced. If the difference between the diameter of the connection hole on the structural member and the diameter of the connection hole on the box body 11 is greater than 1mm, the first clamping portion 401 of the rivet 400 will be located inside the connection hole on the structural member, resulting in the first clamping portion 401 of the rivet 400 being unable to clamp the structural member, and thus the box body 11 and the structural member cannot be connected together. Therefore, by ensuring that the difference between the diameter of the connection hole on the structural member and the diameter of the connection hole on the box body 11 is greater than or equal to 0.5mm and less than or equal to 1mm, the penetration portion 403 of the rivet 400 can easily penetrate the connection hole of the structural member and the connection hole of the box body 11. At the same time, the first clamping portion 401 of the rivet 400 can clamp the structural member, thereby allowing the box body 11 and the structural member to be connected by riveting.

[0124] For example, see Figure 9 and Figure 10 As shown, the connection hole on the overlapping portion of the mounting angle 600 and the flange 114 of the housing 11 can be a first connection hole 603. The connection hole on the overlapping portion of the flange 114 of the top of the housing 11 and the mounting angle 600 can be a second connection hole 1141. In the height direction of the washing machine, the mounting angle 600 is located on the side of the flange 114 of the top of the housing 11 facing away from the base 16. The diameter of the first connection hole 603 is larger than the diameter of the second connection hole 1141. The difference between the diameters of the first connection hole 603 and the second connection hole 1141 is greater than or equal to 0.5 mm and less than or equal to 1 mm.

[0125] In some embodiments, the housing 11 and the structural member are each provided with at least two connection holes in the overlapping portion. A corresponding rivet 400 is located in each connection hole. In other words, the housing 11 and the structural member are connected via at least two rivets 400. This arrangement can improve the connection strength and stability between the housing 11 and the structural member.

[0126] In some examples, at least two connection holes of a structural member are spaced apart to avoid interference between at least two rivet members 400 corresponding to the structural member.

[0127] For example, see Figure 9 and Figure 10 As shown, the corner 600 is provided with at least two first connection holes 603. The at least two first connection holes 603 are spaced apart. The flange 114 of the box body 11 is provided with at least two second connection holes 1141. The at least two second connection holes 1141 are spaced apart. Each first connection hole 603 and each second connection hole 1141 is correspondingly provided with a rivet 400 (see Figure 7 shown).

[0128] For example, the distance between two adjacent rivets 400 can be less than or equal to 28 mm. For example, the distance between two adjacent rivets 400 can be 23 mm, 24 mm, 25 mm, 26 mm, 27 mm or 28 mm, etc. Of course, the distance can also be other values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the distance between two adjacent rivets 400 is greater than 28 mm, the connection strength of the rivets 400 to the box 11 and the structural parts will be relatively small, which will make it easy for the rivets 400 to fall off from the box 11 and the structural parts when the washing machine falls or vibrates during transportation. By making the distance between two adjacent rivets 400 less than or equal to 28 mm, the connection strength of the rivets 400 to the box 11 and the structural parts can be relatively large, so that the rivets 400 will not easily fall off from the box 11 and the structural parts when the washing machine falls or vibrates during transportation.

[0129] In some embodiments, the chassis 10 further includes an upper connecting plate 18 and a lower connecting plate 19 (see Figure 4 (as shown). The upper connecting plate 18 and the lower connecting plate 19 are located inside the housing 11. The upper connecting plate 18 and the lower connecting plate 19 are connected to the housing 11 on both sides in the width direction of the washing machine, that is, the lower connecting plate 19 is connected to the housing 11 on both sides in the width direction of the washing machine.

[0130] The upper connecting plate 18 is located on the upper side of the lower connecting plate 19 , that is, the upper connecting plate 18 is located on one side of the lower connecting plate 19 in the +Z axis direction.

[0131] The upper connecting plate 18 and the lower connecting plate 19 are provided on the rear side of the box body 11 .

[0132] In some embodiments, the structural member includes at least one of an upper connecting plate 18 and a lower connecting plate 19 .

[0133] For example, the upper connecting plate 18 is connected to the rear side of the housing 11 by means of riveting members 400. The lower connecting plate 19 is also connected to the rear side of the housing 11 by means of riveting members 400. This arrangement, compared to welding, uses riveting to connect both the upper connecting plate 18 to the housing 11 and the lower connecting plate 19 to the housing 11. This eliminates the need for complex equipment and can reduce the production cost of the washing machine.

[0134] In some examples, the shear strength of the upper connecting plate 18 can be greater than or equal to 896 MPa. For example, the shear strength of the upper connecting plate 18 can be 896 MPa, 898 MPa, 900 MPa, 905 MPa, 910 MPa, or 920 MPa. Of course, the shear strength can also be other values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the shear strength of the upper connecting plate 18 is less than 896 MPa, it will cause the rivet 400 to easily fall off from the box body 11 and the upper connecting plate 18 when the washing machine is dropped, impacted by an inclined plane, vibrated, etc. during transportation, and the upper connecting plate 18 will tear. By ensuring that the shear strength of the upper connecting plate 18 is greater than or equal to 896 MPa, it is possible to prevent the rivet 400 from falling off from the box body 11 and the upper connecting plate 18 when the washing machine is dropped, impacted by an inclined plane, vibrated, etc. during transportation, and to prevent the upper connecting plate 18 from tearing.

[0135] The tensile strength of the upper connecting plate 18 can be greater than or equal to 520Mpa. For example, the tensile strength of the upper connecting plate 18 can be 520Mpa, 525Mpa, 530Mpa, 535Mpa, 540Mpa or 550Mpa, etc. Of course, the tensile strength can also be other values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the tensile strength of the upper connecting plate 18 is less than 520Mpa, it will cause the rivet 400 to easily fall off from the box body 11 and the upper connecting plate 18 when the washing machine is dropped, impacted by an inclined plane, vibrated, etc. during transportation, and the upper connecting plate 18 will tear. By ensuring that the tensile strength of the upper connecting plate 18 is greater than or equal to 520Mpa, it is possible to prevent the rivet 400 from falling off from the box body 11 and the upper connecting plate 18 when the washing machine is dropped, impacted by an inclined plane, vibrated, etc. during transportation, and to prevent the upper connecting plate 18 from tearing.

[0136] The shear strength of the lower connecting plate 19 can be greater than or equal to 896 MPa. For example, the shear strength of the lower connecting plate 19 can be 896 MPa, 898 MPa, 900 MPa, 905 MPa, 910 MPa, or 920 MPa, etc. Of course, the shear strength can also be other values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the shear strength of the lower connecting plate 19 is less than 896 MPa, it will cause the rivet 400 to easily fall off from the box body 11 and the lower connecting plate 19 when the washing machine is dropped, impacted by an inclined surface, vibrated, etc. during transportation, and the lower connecting plate 19 will be torn. By ensuring that the shear strength of the lower connecting plate 19 is greater than or equal to 896 MPa, it can be prevented that the rivet 400 falls off from the box body 11 and the lower connecting plate 19 when the washing machine is dropped, impacted by an inclined surface, vibrated, etc. during transportation, and the lower connecting plate 19 can be prevented from torn.

[0137] The tensile strength of the lower connecting plate 19 can be greater than or equal to 520 MPa. For example, the tensile strength of the lower connecting plate 19 can be 520 MPa, 525 MPa, 530 MPa, 535 MPa, 540 MPa or 550 MPa, etc. Of course, the tensile strength can also be other values, and those skilled in the art can choose according to needs, and this embodiment does not limit this. If the tensile strength of the lower connecting plate 19 is less than 520 MPa, it will cause the rivet 400 to easily fall off from the box body 11 and the lower connecting plate 19 when the washing machine is dropped, impacted by an inclined surface, vibrated, etc. during transportation, and the lower connecting plate 19 will be torn. By ensuring that the tensile strength of the lower connecting plate 19 is greater than or equal to 520 MPa, it can be prevented that the rivet 400 falls off from the box body 11 and the lower connecting plate 19 when the washing machine is dropped, impacted by an inclined surface, vibrated, etc. during transportation, and the lower connecting plate 19 can be prevented from torn.

[0138] For some examples, see Figures 11 to 14 As shown, a first concave-convex structure 1111 is provided on at least one first wall 111 at a position corresponding to the barrel assembly.

[0139] For example, see Figure 15 As shown, in the width direction of the washing machine, the two first walls 111 can be provided with first concave-convex structures 1111 at positions corresponding to the axis of the outer tub 202. The first concave-convex structures 1111 on the two first walls 111 are symmetrically arranged relative to the axis of the outer tub 202.

[0140] In some embodiments, the first wall 111 may be pressed to form a first concave-convex structure 1111 through a mold forming process.

[0141] Among them, see Figures 14 to 17As shown, the first concave-convex structure 1111 is a first concave structure 111a on the side of the first wall 111 facing the outer cylinder 202. The first concave structure 111a is used to avoid the cylinder assembly, that is, the first concave structure 111a can prevent the cylinder assembly from interfering with the box body 11.

[0142] The first concave-convex structure 1111 is formed as a first convex structure 111b on the side of the first wall 111 facing away from the outer drum 202. This arrangement increases the volume of the chassis 10 while maintaining the same size, thereby increasing the operating space of the inner drum assembly of the washing machine and preventing the drum assembly from colliding with the chassis 10. Furthermore, the volume of the drum assembly can be increased, thereby reducing the production cost of the washing machine.

[0143] Exemplarily, first concave-convex structures 1111 are respectively provided on the two first walls 111 at the positions of the corresponding drum assemblies. The first concave-convex structure 1111 is a first concave structure 111a on the side of the first wall 111 facing the outer drum 202, and the first concave-convex structure 1111 is a first convex structure 111b on the side of the first wall 111 away from the outer drum 202, which can increase the volume of the inner drum assembly of the washing machine to 105L and the maximum capacity of the inner drum assembly of the washing machine to 20kg.

[0144] By providing a first concave-convex structure 1111 on at least one first wall 111 of the box body 11, the rigidity of the box body 11 can be increased, the natural frequency of the box body 11 can be improved, the vibration noise of the washing machine can be improved, and the balance performance of the drum assembly and the transportation performance of the entire machine can be improved.

[0145] In some embodiments, the first concave-convex structure 1111 extends along the height direction of the washing machine. In this way, the first concave structure 111a extends along the height direction of the washing machine, so that the drum assembly does not contact the housing 11 in the height direction of the washing machine, thereby preventing the drum assembly from hitting the chassis 10.

[0146] In some examples, the housing 11 may have an upper edge 11a and a lower edge 11b in the height direction of the washing machine (see FIG. Figure 13 The edge at the top of the box body 11 may be an upper edge 11a. The edge at the bottom of the box body 11 may be a lower edge 11b.

[0147] In the height direction of the washing machine, the first concave-convex structure 1111 may be spaced apart from the upper edge 11a by a distance D1 (see Figure 13As shown). Wherein D1 is greater than or equal to 5mm. For example, the value of D1 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or 20mm, etc. Of course, the spacing can also be other numerical values, and those skilled in the art can choose according to their needs, and this embodiment does not limit this. If the spacing between the first concave-convex structure 1111 and the upper edge 11a is less than 5mm, it will lead to an increase in the difficulty of manufacturing the mold for forming the first concave-convex structure 1111, which will increase the production cost of the washing machine. By making the spacing between the first concave-convex structure 1111 and the upper edge 11a greater than or equal to 5mm, the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 can be reduced, thereby reducing the production cost of the washing machine.

[0148] In some examples, in the height direction of the washing machine, the first concave-convex structure 1111 may be spaced apart from the lower edge 11b by a distance D2 (see Figure 13 As shown). Wherein, D2 is greater than 5mm. For example, the value of D2 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or 20mm, etc. Of course, the spacing can also be other values, and those skilled in the art can choose according to needs, and this embodiment is not limited to this. If the spacing between the first concave-convex structure 1111 and the lower edge 11b is less than 5mm, it will lead to an increase in the difficulty of manufacturing the mold for forming the first concave-convex structure 1111, which will increase the production cost of the washing machine. By making the spacing between the first concave-convex structure 1111 and the lower edge 11b greater than or equal to 5mm, the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 can be reduced, thereby reducing the production cost of the washing machine.

[0149] In some embodiments, the first concave-convex structure 1111 is symmetrically arranged with respect to the axis of the outer drum 202 in the depth direction of the washing machine. With this arrangement, the projection of the outer drum 202 away from the axis of the outer drum 202 in the width direction of the washing machine falls within the projection area of ​​the first concave-convex structure 1111. That is, the projection of the outer drum 202 close to the first wall 111 in the width direction of the washing machine falls within the projection area of ​​the first concave-convex structure 1111.

[0150] In some examples, the first raised structure 111b may have a first edge 11c (see Figure 13 As shown). Exemplarily, the edge of the first protruding structure 111b on the side in the -X axis direction is the first edge 11c.

[0151] The first protruding structure 111b may have a second edge 11d. For example, the edge of the first protruding structure 111b on one side of the +X axis direction is the second edge 11d. Along the depth direction of the washing machine, the second edge 11d is arranged opposite to the first edge 11c.

[0152] In some examples, the surface of the first wall 111 facing away from the outer cylinder 202 and not provided with the first protruding structure 111b is a first surface 11e. The connection between the first edge 11c and the first surface 11e may have a first straight line segment. The connection between the second edge 11d and the first surface 11e may have a second straight line segment.

[0153] The first straight line segment may have a first center point 11c1. In the height direction of the washing machine, portions of the first straight line segment located on both sides of the first center point 11c1 are symmetrically arranged relative to the first center point 11c1.

[0154] The second straight line segment may have a second center point 11d1. In the height direction of the washing machine, portions of the second edge 11d located on both sides of the second center point 11d1 are symmetrically arranged relative to the second center point 11d1.

[0155] A line connecting the second center point 11d1 and the first center point 11c1 forms a center line C. The center line C extends along the depth direction of the washing machine.

[0156] The distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine is L2. For example, the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine can be the dimension of the center line C in the depth direction of the washing machine. In other words, the dimension of the center line C in the depth direction of the washing machine is L2.

[0157] In some examples, L2 is greater than or equal to 139 mm and less than or equal to 537 mm. For example, the value of L2 can be 139 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, or 537 mm. Of course, L2 can also be other values, and those skilled in the art can select them according to their needs. This embodiment does not limit this. If L2 is less than 139 mm, the strength of the housing 11 will be insufficient, which may cause the housing 11 to deform during operation of the washing machine. If L2 is greater than 537 mm, the first concave-convex structure 1111 will be too close to the edge of the first wall 111, which will increase the difficulty of manufacturing the mold for forming the first concave-convex structure 1111. By limiting the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine, deformation of the housing 11 during operation of the washing machine can be avoided, and the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 can be reduced.

[0158] In some examples, the dimension of the first wall 111 in the depth direction of the washing machine is L3. The ratio of L2 to L3 is greater than or equal to 0.26 and less than or equal to 0.55. For example, the ratio of L2 to L3 can be 0.26, 0.3, 0.35, 0.4, 0.45, or 0.55. Of course, the ratio of L2 to L3 can also be other values, and those skilled in the art can select it according to their needs, and this embodiment does not limit this. If the ratio of L2 to L3 is less than 0.26, the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine will be too small, which will result in insufficient strength of the housing 11 and deformation of the housing during operation. If the ratio of L2 to L3 is greater than 0.55, the distance between the first edge 11c and the second edge 11d in the depth direction of the washing machine will be too large, which will cause the first concave-convex structure 1111 to be too close to the edge of the first wall 111, increasing the difficulty of manufacturing the mold for forming the first concave-convex structure 1111. By limiting the ratio of L2 to L3, deformation of the cabinet during operation of the washing machine can be avoided, and the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 can be reduced.

[0159] See also Figure 15 and Figure 16 As shown, in the width direction of the washing machine, the distance between the side of the first wall 111 facing away from the outer drum 202 and the outer drum 202 may be D3. The distance between the first concave-convex structure 1111 and the outer drum 202 may be D4. The size of the first concave-convex structure 1111 may be L4.

[0160] Where D3 satisfies: D3 = D4 + L4. This arrangement allows the capacity of the chassis 10 to be increased while the dimensions of the chassis 10 remain unchanged, thanks to the first concave structure 111a of the first concave-convex structure 1111, preventing the outer cylinder 202 from striking the chassis 10 when its position is away from the axis of the outer cylinder 202. While the dimensions of the chassis 10 remain unchanged, the volume of the cylinder assembly can be increased by the space between the first concave-convex structure 1111 and the outer cylinder 202, as well as the space within the first concave structure 111a of the first concave-convex structure 1111.

[0161] In some embodiments, the cross-section of the first protrusion structure 111b can be trapezoidal. This configuration simplifies the mold for forming the first concave-convex structure 1111, reducing the difficulty of manufacturing the first concave-convex structure 1111. It also increases the strength of the first wall 111, effectively dispersing and transmitting externally applied forces, and reducing stress concentration.

[0162] For example, in a plane perpendicular to the height direction of the washing machine, that is, in a plane formed by the X-axis and the Y-axis, the cross section of the first protrusion structure 111b may be arranged in a trapezoidal shape. Figure 17As described above, the size of the cross section of the first protrusion structure 111 b in the X-axis direction gradually decreases along the −Y-axis direction.

[0163] In some embodiments, see Figure 17 As shown, in the width direction of the washing machine, the size of the first raised structure 111b is L1. Wherein, L1 is less than or equal to 5mm. For example, the value of L1 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm or 5mm, etc. Of course, the size of the first raised structure 111b can also be other values, and those skilled in the art can choose according to their needs. This is not limited in this embodiment. If the size of the first raised structure 111b is greater than 5mm, the size of the packaging of the washing machine will increase, which will increase the transportation cost of the washing machine. By making the size of the first raised structure 111b less than or equal to 5mm, the size of the packaging of the washing machine will not increase, thereby reducing the transportation cost of the washing machine.

[0164] In some embodiments, in the depth direction of the washing machine, the first concave-convex structure 1111 may be provided with a second concave-convex structure 1112 on both sides thereof (see FIG. Figures 11 to 14 ,as well as Figure 18 As shown). The second concave-convex structure 1112 is spaced apart from the first concave-convex structure 1111. By providing the first concave-convex structure 1111 and the second concave-convex structure 1112 on the first wall 111 of the housing 11, the rigidity of the housing 11 can be increased, the natural frequency of the housing 11 can be improved, the vibration noise of the washing machine can be reduced, and the balance performance of the drum assembly and the transport performance of the entire washing machine can be improved.

[0165] See also Figure 19 and Figure 20 As shown, the second concave-convex structure 1112 is a second concave structure 111c on the side of the first wall 111 facing the interior of the box body 11; and the second concave-convex structure 1112 is a second convex structure 111d on the side of the first wall 111 facing away from the interior of the box body 11. This arrangement can increase the volume of the box body 10 while keeping the size of the box body 10 unchanged.

[0166] For example, each of the two first walls 111 of the housing 11 may be provided with a first concave-convex structure 1111 and two second concave-convex structures 1112. In the depth direction of the washing machine, the two second concave-convex structures 1112 are symmetrically arranged relative to the first concave-convex structure 1111.

[0167] In some embodiments, in the depth direction of the washing machine, the distance between the second concave-convex structure 1112 and the first concave-convex structure 1111 is D5 (see Figure 13As shown). Wherein, D5 is greater than or equal to 5mm. For example, the value of D5 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or 20mm, etc. Of course, the spacing can also be other numerical values, and those skilled in the art can choose according to their needs, and this embodiment does not limit this. If the spacing between the second concave-convex structure 1112 and the first concave-convex structure 1111 is less than 5mm, it will lead to an increase in the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 and the second concave-convex structure 1112, which will increase the production cost of the washing machine. By making the spacing between the second concave-convex structure 1112 and the first concave-convex structure 1111 greater than or equal to 5mm, the difficulty of manufacturing the mold for forming the first concave-convex structure 1111 and the second concave-convex structure 1112 can be reduced, thereby reducing the production cost of the washing machine.

[0168] In some embodiments, in the depth direction of the washing machine, the distance between the second concave-convex structure 1112 and the arc corner 113 may be D6 (see Figure 13 As shown). Wherein, D6 is greater than or equal to 25 mm. For example, the value of D6 can be 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm or 40 mm, etc. Of course, the spacing can also be other values, and those skilled in the art can choose according to their needs, and this embodiment does not limit this. If the spacing between the second concave-convex structure 1112 and the arc angle 113 is less than 25 mm, the folding knife of the bending machine will have insufficient movement stroke during the bending process of the material forming the box body 11, so that the arc angle 113 cannot be formed between the second wall 112 and the first wall 111. By ensuring that the spacing between the second concave-convex structure 1112 and the arc angle 113 is greater than or equal to 25 mm, the folding knife of the bending machine can have sufficient movement stroke during the bending process of the material forming the box body 11, so that the arc angle 113 can be formed between the second wall 112 and the first wall 111.

[0169] In some embodiments, the chassis 10 further includes a buckle 17 (see Figures 11 to 13 As shown). The buckle 17 is provided on the housing 11. The buckle 17 is used to carry the washing machine.

[0170] For example, the handle 17 may be connected to the second concave-convex structure 1112 on the first wall 111 of the box body 11. The handle 17 may be embedded in the second convex structure 111d.

[0171] It should be noted that to meet people's demand for larger washing capacity, the size of the washing machine cabinet 10 and the drum assembly (including the inner drum 200 and the outer drum) has also increased accordingly. However, this increase in size can lead to eccentricity and vibration problems when the inner drum 200 rotates relative to the outer drum.

[0172] As the size of the washing machine's chassis 10 and drum assembly increases, the inner drum 200 is prone to eccentricity during rotation due to uneven distribution of clothing. Eccentricity refers to the misalignment of the inner drum 200's rotational center with its geometric center, resulting in unbalanced centrifugal forces during rotation. This centrifugal force can cause vibration in the washing machine, especially during the spin cycle, when the inner drum 200 spins at high speeds. This eccentricity can be significant.

[0173] To mitigate or eliminate vibrations caused by eccentricity, washing machine drum assemblies are typically equipped with a balancing unit 300. However, as washing machine size increases, the eccentricity and vibration of the inner drum 200 also increase, which can affect the performance and stability of the balancing unit 300. Once the connection stability is compromised, the balancing unit 300 may not maintain the expected synchronous rotation, leading to problems such as shaking, loosening, and even falling off. These problems not only reduce the washing machine's dehydration efficiency, but can also generate noise and even damage the washing machine's structure, shortening its service life.

[0174] To improve user experience, Figures 21 to 23 As shown, in some embodiments, a bearing portion 210 may be provided at the opening of the inner cylinder 200. The bearing portion 210 may be a flange provided at the opening of the inner cylinder 200. The bearing portion 210 extends away from the axis of the inner cylinder 200. The diameter of the end of the bearing portion 210 away from the axis of the inner cylinder 200 is greater than the diameter of the inner cylinder 200.

[0175] Combine Figure 24 As shown, the opening of the inner cylinder 200 may also be provided with a rivet portion 240. The bottom end of the rivet portion 240 may be connected to the end of the support portion 210 facing away from the opening of the inner cylinder 200. The rivet portion 240 extends along the height direction of the inner cylinder 200. The rivet portion 240 may be provided above the opening of the inner cylinder 200 to form a receiving area. The diameter of the receiving area is larger than the diameter of the inner cylinder 200.

[0176] For example, the balancing portion 300 may be a balancing ring. The balancing ring may be composed of an upper balancing portion and a lower balancing portion. The upper and lower balancing portions are connected by heat pressing to achieve a seal. The upper and lower balancing portions may enclose a cavity 320 for containing a balancing liquid.

[0177] Combine Figure 24 As shown, a protruding connector 310 may be provided on the circumference of the lower balancing portion. The connector 310 may be integrally formed with the lower balancing portion. The integrally formed lower balancing portion and connector 310 provide a high connection strength, capable of withstanding large external forces and pressures, and helping to improve the connection stability between the balancing portion 300 and the inner cylinder 200.

[0178] The connector 310 of the balancing part 300 can be connected to the rivet part 240. The balancing part 300 is fixed to the inner cylinder 200 through the connector 310, which can help balance the eccentric mass of the inner cylinder 200 and reduce vibration during rotation.

[0179] The inner diameter of the riveted portion 240 may be larger than the outer diameter of the connector 310 , so that the connector 310 can smoothly enter the accommodating area surrounded by the riveted portion 240 , thereby achieving connection between the connector 310 and the riveted portion 240 .

[0180] The rivet portion 240 can be connected to the connector 310 through a rotary riveting process. It should be noted that rotary riveting, also known as riveting or roll riveting, is a riveting process developed based on the principle of cold rolling. The rotary riveting process primarily involves the eccentric rotation of the riveting head on the riveting machine, which continuously compresses the circumference of the rivet portion 240, thereby pressing the rivet portion 240 against the connector 310. Because the rotary riveting method tightly connects the rivet portion 240 and the connector 310, the connection is very secure. Furthermore, the rotary riveting connection does not form a protrusion at the joint, resulting in an aesthetically pleasing appearance.

[0181] As will be appreciated, if the gap between the rivet portion 240 and the connector 310 is too large, it will hinder the tight connection between the rivet portion 240 and the connector 310 after riveting. If the gap between the rivet portion 240 and the connector 310 is too small, it will not be easy for the balancing portion 300 to enter the accommodation area enclosed by the rivet portion 240. For example, the inner diameter of the rivet portion 240 can be 0.1 mm to 0.3 mm larger than the outer diameter of the connector 310. This facilitates the balancing portion 300 to enter the rivet portion 240 during processing and facilitates the tight connection between the rivet portion 240 and the connector 310 after riveting.

[0182] Combine Figure 25 As shown, after a portion of the riveted portion 240 is subjected to a spin riveting process, a connecting portion 220 can be formed. The connecting portion 220 is connected to the bearing portion 210 along the bottom portion of the inner cylinder in the height direction. The connecting portion 220 is disposed around the circumference of the connecting member 310. The connecting portion 220 abuts against the side surface of the connecting member 310. The connecting portion 220 can limit the position of the connecting member 310 from the circumference of the connecting member 310, ensuring that the balancing portion 300 and the inner cylinder 200 remain coaxial.

[0183] After the riveted portion 240 is partially riveted, a reinforcement portion 230 can be formed. The reinforcement portion 230 is connected to the top of the connecting portion 220 along the height direction of the inner cylinder. The reinforcement portion 230 can be arranged perpendicular to the connecting portion 220. The reinforcement portion 230 abuts the top surface of the connecting member 310. The reinforcement portion 230, the supporting portion 210, and the connecting portion 220 can enclose a cavity capable of accommodating the connecting member 310. The reinforcement portion 230 and the supporting portion 210 are distributed on both sides of the connecting member 310 along the height direction of the inner cylinder 200, thereby supporting the balancing portion 300 in the height direction of the inner cylinder 200 and limiting its movement in the height direction of the inner cylinder 200.

[0184] In some embodiments, along the axial direction of the balancing portion, the connecting member 310 may be provided with a sixth limiting portion 311. The sixth limiting portion 311 may be provided on a side of the connecting member 310 facing the reinforcing portion 230.

[0185] As a riveting process, spin riveting also has the characteristics of strong adaptability and can adapt to the shape of the structure to be riveted, that is, the connecting member 310. Figure 25 As shown, during the riveting process, the position of the riveting portion 240 corresponding to the sixth limiting portion 311 can form the fifth limiting portion 231 .

[0186] The fifth stopper 231 is located on the side of the reinforcement portion 230 facing the connector 310. The bearing portion 210 and the fifth stopper 231 are located on both sides of the connector 310 along the height direction of the inner cylinder 200. The bearing portion 210 and the fifth stopper 231 respectively abut against both ends of the connector 310 along the height direction of the inner cylinder 200 to limit the movement of the balancing portion 300 along the height direction of the inner cylinder 200.

[0187] At least a portion of the fifth stopper 231 abuts against the sixth stopper 311. This locks the relative position of the reinforcement portion 230 and the connector 310. This not only limits the movement of the balancing portion 300 along the height direction of the inner cylinder 200, but also effectively limits the relative rotation of the reinforcement portion 230 and the connector 310. This, in turn, limits the relative rotation of the balancing portion 300 and the inner cylinder 200, achieving a stable connection between the balancing portion 300 and the inner cylinder 200.

[0188] The fifth limiting portion 231 and the sixth limiting portion 311 abut against each other along the axial direction of the balancing portion. The connection length between the fifth limiting portion 231 and the sixth limiting portion 311 can be set based on the actual height of the connecting member 310 along the height direction of the inner cylinder 200, so as to form an effective connection length between the fifth limiting portion 231 and the sixth limiting portion 311.

[0189] In some possible implementations, the balancing part 300 may be a plastic part comprising at least polypropylene. The plastic balancing part 300 is lightweight, flexible, and has good high and low temperature resistance and corrosion resistance, meeting the requirements of washing machines in various environments.

[0190] In some embodiments, the balancing part 300 can be a plastic component comprising polypropylene and calcium carbonate. Adding calcium carbonate to polypropylene significantly improves the material's rigidity, heat resistance, and dimensional stability. Furthermore, calcium carbonate is less expensive than polypropylene. The addition of calcium carbonate can also reduce the production cost of the balancing part 300, improving the product's cost-effectiveness.

[0191] For example, the plastic part can be made of polypropylene combined with at least 10% calcium carbonate. When the calcium carbonate content in polypropylene is at least 10%, the resulting plastic part maintains good strength and toughness to withstand the forces generated by high-speed rotation in a washing machine. Furthermore, the flexibility of polypropylene ensures that the plastic part is not easily broken or deformed by external forces.

[0192] Combine Figure 25 and Figure 26 As shown, in some possible embodiments, one of the fifth limiting portion 231 and the sixth limiting portion 311 can be a plug-in interface, and the other can be a protrusion. The protrusion is inserted into the plug-in interface. The combination of the plug-in interface and the protrusion provides a simple and effective mechanical connection. The combination of the plug-in interface and the protrusion enables a quick and reliable connection, ensuring the stability of the balancing portion 300 on the inner cylinder 200. The protrusion is inserted into the plug-in interface, providing a fixed connection point and realizing a self-locking function, limiting the rotation and movement of the balancing portion 300 along the axis of the inner cylinder 200.

[0193] Combine Figure 26 As shown, in some possible embodiments, the sixth limiting portion 311 can be configured as a protrusion. The protrusion can be integrally formed with the connector 310, for example, during injection molding or machining. The integrally formed protrusion and connector 310 provide a strong connection, allowing the protrusion to withstand large external forces, thereby improving connection effectiveness and effectively limiting relative rotation between the balancing portion 300 and the inner cylinder 200.

[0194] The fifth limiting portion 231 can be configured as an insertion port. During the riveting process, the position of the riveting portion 240 corresponding to the protrusion can be press-formed to form an insertion port with an opening toward the protrusion. The opening shape of the insertion port matches the edge profile of the protrusion.

[0195] The protrusion can protrude upward along the height direction of the inner cylinder 200. The protrusion is inserted into the insertion port. By inserting the protrusion into the insertion port, a stable mechanical connection is formed, effectively limiting the relative movement between the connecting member 310 and the fifth limiting portion 231, thereby limiting the rotation of the balancing portion 300 around the axis of the inner cylinder 200, and improving the connection stability between the balancing portion 300 and the inner cylinder 200.

[0196] Combine Figure 25 As shown, in some other possible embodiments, the sixth limiting portion 311 may be provided with an insertion port. The insertion port is provided on the surface of the connector 310 along the height direction of the inner cylinder 200 and extends along the height direction of the inner cylinder 200. The insertion port serves as a receiving structure capable of accommodating the fifth limiting portion 231, providing a fixing point so that the balancing portion 300 can be securely mounted on the inner cylinder 200.

[0197] The fifth limiting portion 231 can be configured as a protrusion. During the riveting process, the position of the riveted portion 240 corresponding to the plug interface is press-formed to form a protrusion that protrudes toward the plug interface. The edge profile of the protrusion matches the opening shape of the plug interface. The protrusion is formed in a simple manner, and after forming, the protrusion and the plug interface fit tightly together, which can improve the effectiveness of the connection. After the riveted portion 240 and the connector 310 are riveted together, the formed reinforcement portion 230 abuts the upper surface of the connector 310 along the height direction of the inner cylinder 200, thereby tightly abutting the connector 310.

[0198] The protrusion can protrude downward along the height direction of the inner cylinder 200. The protrusion is inserted into the insertion port. By inserting the protrusion into the insertion port, a stable mechanical connection is formed, effectively limiting the relative movement between the connecting member 310 and the fifth limiting portion 231, thereby limiting the rotation of the balancing portion 300 around the axis of the inner cylinder 200, and improving the connection stability between the balancing portion 300 and the inner cylinder 200.

[0199] Combine Figure 27 and Figure 28 As shown, in some possible embodiments, the number of the sixth limiting portion 311 can be multiple. The number of the fifth limiting portion 231 can be multiple. Among them, the fifth limiting portion 231 and the sixth limiting portion 311 are arranged correspondingly. After the multiple fifth limiting portions 231 and the sixth limiting portions 311 are correspondingly abutted, multiple connection points can be formed in the circumferential direction of the balancing portion 300. Multiple connection points can disperse the stress during rotation and reduce the load on a single connection point. Multiple connection points can provide stable support to prevent the balancing portion 300 from loosening and shifting. Especially under high-speed rotation and vibration conditions, the reliability of the connection can be effectively improved.

[0200] Multiple sixth stoppers 311 are spaced apart along the circumference of the balancing portion 300. These spaced-apart sixth stoppers 311 disperse the connection points along the axial direction of the balancing portion 300, providing omnidirectional support for the balancing portion 300. This design effectively offsets centrifugal and unbalanced forces generated during rotation, improving the stability of the washing machine.

[0201] In some embodiments, the plurality of sixth limiting portions 311 can be divided into a plurality of groups, and the sixth limiting portions 311 in each group can be arranged at equal intervals along the circumference of the balancing portion 300. The sixth limiting portions 311 in each group can be arranged at equal intervals. By grouping and arranging at equal intervals, each group and the limiting portions within each group can provide stable support.

[0202] In other embodiments, multiple sixth limiting portions 311 are arranged at equal intervals along the circumference of the balancing portion 300. This arrangement distributes the limiting portions around the balancing portion 300, providing support points in all directions. This provides both support and restraint, reduces the possibility of uneven force at each connection point, and achieves all-round support for the balancing portion 300. The equally spaced sixth limiting portions 311 standardize and simplify the design process, while also simplifying the manufacturing process, thereby improving production efficiency and reducing costs.

[0203] In some possible implementations, the number of the fifth limiting portions 231 and the number of the sixth limiting portions 311 may be equal to six.

[0204] It is understood that when the number of fifth limiting portions 231 and the number of sixth limiting portions 311 is less than six, the number of connection points provided after connection is small, resulting in a large impact force on the fifth limiting portion 231 and the sixth limiting portion 311 at each connection point, which can easily cause overload or wear of the fifth limiting portion 231 and the sixth limiting portion 311, shortening the service life of the washing machine. When the number of fifth limiting portions 231 and the number of sixth limiting portions 311 is set to six, a relatively large number of connection points can be provided, which can effectively disperse the forces generated by the balancing portion 300 and the inner drum 200 during operation, helping to reduce overload and wear.

[0205] In other embodiments, the number of fifth stoppers 231 and sixth stoppers 311 can be greater than six. The number of fifth stoppers 231 and sixth stoppers 311 can provide support points, helping to reduce vibration and imbalance caused by single-point support. Because the load is distributed, wear on each stopper is reduced, thereby extending the life of the washing machine.

[0206] In some possible implementations, along the circumference of the inner cylinder 200 , the length of the protrusion may be equal to 15 mm.

[0207] It is understandable that when the length of the protrusion is less than 15 mm, the contact area after the protrusion is connected to the plug interface is small, which can easily lead to low connection strength between the protrusion and the plug interface. Especially as the size of the washing machine increases, the eccentricity and vibration of the inner drum 200 also increase. The connection strength between the protrusion and the plug interface is insufficient, which can easily affect the performance and stability of the balancing part 300.

[0208] By setting the length of the protrusion to 15 mm, sufficient support force can be provided in the circumferential direction, reducing the impact of shear stress caused by rotation on the connection.

[0209] In some embodiments, the length of the protrusion along the circumference of the inner cylinder 200 can be greater than 15 mm. A longer protrusion is stronger, thereby enhancing the connection strength between the plug interface and the protrusion. This helps to resist circumferential shear forces during rotation.

[0210] Combine Figure 28 As shown, correspondingly, if the protrusion can be inserted into the plug interface, the length L5 of the plug interface can be greater than 15 mm. This length can ensure that the protrusion can be smoothly connected to the plug interface and provide an effective contact area.

[0211] In some possible implementations, along the radial direction of the inner cylinder 200 , the width of the protrusion may be equal to 5 mm.

[0212] It is understandable that when the width of the protrusion is less than 5 mm, after the protrusion is connected to the plug port, the contact area in the radial direction of the inner cylinder 200 is small, which will affect its radial rigidity and stability.

[0213] Increasing the contact area in mechanical connections is an effective way to improve joint strength. Increasing the width of the protrusion can increase this contact area. Setting the protrusion width to 5 mm ensures radial rigidity and stability, preventing bending or deformation during high-speed rotation.

[0214] In some embodiments, the width of the protrusion can be greater than 5 mm along the radial direction of the inner cylinder 200. The increase in width means that the protrusion has radial bending resistance, which helps maintain the stability of the connection during rotation and prevents deformation caused by centrifugal force.

[0215] In some possible implementations, along the height direction of the inner cylinder 200 , the height of the protrusion may be greater than or equal to 3 mm.

[0216] It is understandable that when the height of the protrusion is less than 3 mm, it is difficult to ensure that the protrusion is effectively inserted into the plug interface, which is not conducive to achieving a reliable mechanical connection and providing sufficient limiting effect.

[0217] The height setting must ensure that the protrusion can achieve a self-locking function within the plug-in interface, preventing loosening due to vibration or external forces. By setting the protrusion height equal to or greater than 3 mm, the protrusion can be effectively inserted into the plug-in interface, increasing the effective plug-in length, providing a restraining effect, and ensuring the stability of the balancing portion 300.

[0218] Combine Figure 24 As shown, in some possible implementations, along the height direction of the inner cylinder 200 , the height H1 of the connector 310 may be greater than or equal to 3 mm.

[0219] It is understood that both ends of the connecting member 310 in the height direction abut against the bearing portion 210 and the fifth limiting portion 231, respectively, to limit the movement of the balancing portion 300 in the height direction of the inner cylinder 200. If the height H1 of the connecting member 310 is less than 3 mm, the bending resistance of the connecting member 310 in the height direction of the inner cylinder 200 will be insufficient, and it will be prone to fracture and failure.

[0220] In mechanical connections, increasing height can improve structural rigidity and stability. A taller connector 310 provides vertical support to counteract the effects of the weight of the balancing unit 300 and other stresses generated by its rotation. Setting the height H1 of the connector 310 to greater than or equal to 3 mm provides support, thereby enhancing the stability and vibration resistance of the connection.

[0221] Combine Figure 29 As shown, when the sixth limiting portion 311 is configured as an insertion port, the depth of the insertion port can be equal to the height H1 of the connector 310, that is, the insertion port can penetrate the connector 310 along the height direction of the inner cylinder 200. This can increase the effective insertion length of the protrusion, provide a limiting effect, and ensure the stability of the balancing portion 300.

[0222] Combine Figure 24 As shown, in some possible implementations, along the radial direction of the inner cylinder 200 , the width L6 of the connecting member 310 may be greater than or equal to 5 mm.

[0223] As will be appreciated, the ends of the connector 310 in the height direction abut against the load-bearing portion 210 and the fifth stopper 231, respectively. When the width of the connector 310 is less than 5 mm, the contact area between the ends of the connector 310 in the height direction and the load-bearing portion 210 and the fifth stopper 231 is relatively small. This reduces the support and limiting effect of the load-bearing portion 210 and the fifth stopper 231 on the connector 310, making the connector 310 more susceptible to movement along the height of the inner cylinder 200. By setting the width L6 of the connector 310 to be greater than or equal to 5 mm, the contact area between the connector 310, the load-bearing portion 210, and the fifth stopper 231 can be effectively increased, thereby improving the connection stability between the balancing portion 300 and the inner cylinder 200.
