Description

Technical Field

[0001] Some embodiments of this application relate to the field of household appliance technology, and in particular to a pulsator washing machine. Background Technology

[0002] Top-loading washing machines rely on a balancing section on the inner drum to maintain eccentric balance during the spin-drying stage. When the inner drum rotates eccentrically, water or other liquids within the balancing section concentrate in the opposite direction of the eccentricity, thus balancing the eccentric mass of the inner drum.

[0003] The balancing unit and the inner tub are fixed together with screws or similar fasteners so that the balancing unit can rotate synchronously with the inner tub. However, connection failures can easily occur between the balancing unit and the inner tub, causing the balancing unit to wobble or become loose. Utility Model Content

[0004] Some embodiments of this application provide a pulsator washing machine that can solve the problem of connection failure between the balance section and the inner tub, which causes the balance section to wobble or become loose.

[0005] Some embodiments of this application provide a pulsator washing machine, including:

[0006] Box;

[0007] A frame is provided on the top of the box body, and the frame has a delivery port;

[0008] Cylinder assembly, including:

[0009] The outer cylinder is disposed inside the box;

[0010] The inner drum is rotatably disposed inside the outer drum; the inner drum has a washing chamber, the opening of the inner drum is connected to the washing chamber and faces the dispensing port; the opening of the inner drum is provided with a supporting part and a fifth limiting part connected to each other, the supporting part and the fifth limiting part are arranged along the height direction of the inner drum;

[0011] A balancing part is provided at the opening of the inner cylinder; the balancing part has a protruding connecting member on its periphery; the connecting member has a sixth limiting part on the side facing the dispensing port;

[0012] The bearing portion abuts against at least a portion of the lower end of the connector along the height direction of the inner cylinder, and the fifth limiting portion abuts against at least a portion of the upper end of the connector along the height direction of the inner cylinder, so as to restrict the relative movement of the balancing portion and the inner cylinder.

[0013] At least a portion of the fifth limiting part abuts against the sixth limiting part to restrict the rotation of the balancing part about the axis of the inner cylinder.

[0014] In some embodiments of the pulsator washing machine of this application, the supporting part and the fifth limiting part abut against the two ends of the connecting member along the height direction of the inner drum, respectively, which can support and restrict the movement of the balancing part in the height direction of the inner drum, ensuring that the balancing part remains in the correct position. The abutment between the sixth limiting part and the fifth limiting part restricts the rotation of the balancing part around the axis of the inner drum, ensuring that it does not deviate during high-speed rotation. The connection between the sixth limiting part and the fifth limiting part has high strength and can withstand large tensile forces, shear forces, and impacts. The abutment connection between the sixth limiting part and the fifth limiting part does not require additional connecting parts, and will not cause loosening or damage due to insufficient or excessive torque during installation. Under conditions of excessive vibration or frequent impact, the abutment connection remains stable and is not easily loosened. Therefore, the connection between the balancing part and the inner drum has strong stability and effectiveness, avoiding the problem of the balancing part shaking or loosening during high-speed rotation.

[0015] In some embodiments of this application, one of the fifth limiting portion and the sixth limiting portion is a plug-in interface and the other is a protrusion. The edge contour of the protrusion matches the opening shape of the plug-in interface, and the protrusion passes through the plug-in interface.

[0016] In this configuration, the plug-in interface, acting as a receiving structure, can accommodate the protruding part. The protruding part, as a protruding structure, can be inserted into the plug-in interface to achieve a mechanical connection. The protruding part, passing through the plug-in interface, provides a self-locking function, preventing relative rotation between the connector and the inner cylinder, thereby limiting the relative rotation between the balancing part and the inner cylinder. This plug-in connection utilizes the basic principles of mechanical connection, providing a stable connection effect through shape matching. It ensures the stability and reliability of the balancing part during high-speed rotation in a simple and effective connection method.

[0017] In some embodiments of this application, the fifth limiting portion is provided with an insertion interface;

[0018] The sixth limiting part is configured as a protrusion, which protrudes upward along the height direction of the inner cylinder. The edge contour of the protrusion matches the opening shape of the insertion interface, and the protrusion passes through the insertion interface.

[0019] With this configuration, the protrusion passes through the insertion interface from bottom to top, forming a stable mechanical connection. This effectively restricts the relative movement between the connector and the fifth limiting part, thereby limiting the rotation of the balancing part around the axis of the inner cylinder and improving the connection stability between the balancing part and the inner cylinder.

[0020] In some embodiments of this application, the sixth limiting part is provided with an insertion interface;

[0021] The fifth limiting part is configured as a protrusion, which protrudes downward along the height direction of the inner cylinder. The edge contour of the protrusion matches the opening shape of the insertion interface, and the protrusion passes through the insertion interface.

[0022] With this configuration, the protrusion passes through the insertion interface from top to bottom, forming a stable mechanical connection. This effectively restricts the relative movement between the connector and the fifth limiting part, thereby limiting the rotation of the balancing part around the axis of the inner cylinder and improving the connection stability between the balancing part and the inner cylinder.

[0023] In some embodiments of this application, the number of the sixth limiting portion is multiple, and the number of the fifth limiting portion is multiple;

[0024] The plurality of sixth limiting portions are arranged sequentially at intervals along the circumference of the balancing portion, and the plurality of sixth limiting portions are correspondingly provided with the plurality of fifth limiting portions.

[0025] With this configuration, multiple fifth and sixth limiting parts abut against each other, forming multiple connection points circumferentially on the balancing part. These multiple connection points disperse stress during rotation, reducing the load on individual connection points. They also provide more stable support, preventing loosening and displacement of the balancing part. Especially under high-speed rotation and vibration conditions, this effectively improves the reliability of the connection.

[0026] In some embodiments of this application, the number of the fifth limiting part and the number of the sixth limiting part are both greater than 6.

[0027] When the number of fifth and sixth limiting parts is less than six, the number of connection points available after connection is limited. This results in greater impact forces on the fifth and sixth limiting parts at each connection point, easily causing overload or wear on them, thus affecting the lifespan of the pulsator washing machine. With this arrangement, a relatively larger number of connection points can more effectively distribute the forces generated by the balance section and inner drum during operation, helping to reduce overload or wear.

[0028] In some embodiments of this application, the length of the protrusion is greater than 15 mm along the circumference of the inner cylinder.

[0029] When the length of the protrusion is less than 15 mm, the contact area between the protrusion and the connector is small, which can easily lead to weak connection strength. Especially as the size of the washing machine increases, the eccentricity and vibration of the inner drum also increase, further affecting the performance and stability of the balancing mechanism. This design, with a longer protrusion, provides a larger contact area, thereby enhancing the connection strength between the connector and the protrusion. It also provides sufficient circumferential support, reducing the impact of shear stress generated by rotation on the connection.

[0030] In some embodiments of this application, the width of the protrusion is greater than 5 mm along the radial direction of the inner cylinder.

[0031] When the width of the protrusion is less than 5 mm, the contact area in the radial direction of the inner cylinder is small after the protrusion is connected to the insertion interface, which will affect its radial rigidity and stability. With this design, the increased width of the protrusion means that the protrusion has higher radial rigidity and stability, which helps to maintain the stability of the connection during the rotation of the inner cylinder and prevents the protrusion from bending or deforming during high-speed rotation, thus preventing connection failure.

[0032] In some embodiments of this application, the height of the protrusion is greater than 3 mm along the height direction of the inner cylinder.

[0033] When the height of the protrusion is less than 3 mm, it is difficult to ensure that the protrusion can be effectively inserted into the connector, thus failing to achieve a reliable mechanical connection and provide sufficient restraint. This design increases the insertion length, ensuring that the protrusion can be effectively inserted into the connector to provide better restraint and ensure the stability of the balance section.

[0034] In some embodiments of this application, the opening of the inner cylinder is further provided with:

[0035] A connecting portion is arranged around the outside of the connector; in the height direction of the inner cylinder, the bottom of the connecting portion is connected to the bearing portion, and the top of the connecting portion is connected to the fifth limiting portion;

[0036] A reinforcing part is connected to the top of the connecting part; the reinforcing part is located on the side of the connecting member opposite to the bearing part, and the reinforcing part is connected to the fifth limiting part.

[0037] This design, with the connecting portion encircling the outside of the connector, provides an additional support structure, enhancing the connector's stability and vibration resistance. The reinforcing portion and connecting portion enclose the connector, allowing for a tight fit and forming a high-strength connection. This reduces the likelihood of loosening and ensures that the reinforcing portion, connecting portion, and connector are not easily separated under external forces, improving stability and reliability. The reinforcing portion, located on the side of the connector facing the inlet, restricts the connector's movement in that direction, thereby limiting the movement of the balancing portion along the height of the inner cylinder.

[0038] In some embodiments of this application, the height of the connector is greater than 3 mm along the height direction of the inner cylinder;

[0039] The two ends of the connector in the height direction abut against the bearing part and the fifth limiting part, respectively, to restrict the movement of the balancing part along the height direction of the inner cylinder. If the height of the connector is less than 3 mm, it will result in insufficient bending resistance along the height direction of the inner cylinder, making the connector prone to breakage and failure. With this design, a taller connector can provide greater support, thereby enhancing the stability and vibration resistance of the connection.

[0040] The width of the connector is greater than 5 mm along the radial direction of the inner cylinder.

[0041] The two ends of the connector in the height direction abut against the supporting part and the fifth limiting part, respectively. When the width of the connector is less than 5 mm, the contact area between the two ends of the connector in the height direction and the supporting part and the fifth limiting part is small. This reduces the supporting and limiting effect of the supporting part and the fifth limiting part on the connector, making the connector prone to movement along the height direction of the inner cylinder. This design effectively increases the contact area between the connector and the supporting part and the fifth limiting part, improving the connection stability between the balancing part and the inner cylinder.

[0042] In some embodiments of this application, the balancing part is a plastic component comprising at least polypropylene and calcium carbonate.

[0043] This configuration, involving the addition of calcium carbonate to polypropylene, significantly improves the material's rigidity, heat resistance, and dimensional stability. Furthermore, calcium carbonate is cheaper than polypropylene, and its addition can reduce production costs in the balance section, thereby enhancing the product's cost-effectiveness.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0073] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on some embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] As described in the background section, pulsator washing machines rely on a balancing mechanism on the inner drum to maintain eccentric balance during the spin-drying stage. When the inner drum rotates eccentrically, the balancing mechanism, through the liquid or other medium inside it, automatically flows in the opposite direction of the eccentricity of the inner drum under the action of centrifugal force, thereby balancing the eccentric mass of the inner drum and reducing vibration.

[0075] In related technologies, the balancing unit and the inner tub are fixed together by screws so that the balancing unit can rotate synchronously with the inner tub. However, under long-term use or specific conditions, such as excessive vibration or improper installation, the connection between the balancing unit and the inner tub may loosen or fail. If the connection between the balancing unit and the inner tub is not strong and effective, the balancing unit may wobble or become detached during high-speed rotation. This wobble or detachment will disrupt the balancing function of the balancing unit, causing the eccentric mass of the inner tub to be unbalanced, thus exacerbating the vibration of the washing machine. This vibration not only reduces the washing machine's spin-drying efficiency because it interferes with the normal rotation of the inner tub and the distribution of clothes, but it may also generate noise, affecting the user experience; in extreme cases, it may even damage the structure of the washing machine and shorten its lifespan.

[0076] Furthermore, as the dimensions of the casing and drum assembly of a top-loading washing machine increase, the uneven distribution of clothes during rotation makes it more prone to eccentricity. Eccentricity refers to the misalignment of the drum's rotation center with its geometric center, resulting in an unbalanced centrifugal force during rotation. This centrifugal force causes vibration in the washing machine, especially during the spin-drying stage, where the vibration caused by eccentricity becomes more pronounced when the drum rotates at high speed.

[0077] To mitigate or eliminate vibrations caused by eccentricity, top-loading washing machines typically feature a balancing mechanism in their drum assembly. However, as washing machine sizes increase, the eccentricity and vibration of the inner drum also increase, making the balancing mechanism more susceptible to affecting its performance and stability. If connection stability is compromised, the balancing mechanism may fail to maintain the expected synchronized rotation, leading to problems such as shaking, loosening, or even detachment. These issues not only reduce the washing machine's spin-drying efficiency but can also generate noise and potentially damage the washing machine's structure, affecting its lifespan.

[0078] In view of this, some embodiments of this application provide a pulsator washing machine, including an inner drum and a balancing part, wherein the inner drum is rotatably disposed within an outer drum. The inner drum opening is provided with a bearing part and a fifth limiting part. A protruding connecting member is provided on the periphery of the balancing part. The balancing part is fixed to the inner drum by the connecting member.

[0079] The supporting part abuts against at least a portion of the lower end of the connector along the height direction of the inner cylinder, and the fifth limiting part abuts against at least a portion of the upper end of the connector along the height direction of the inner cylinder. This supports the balancing part and restricts its movement along the height direction of the inner cylinder, ensuring that the balancing part remains in the correct position. The connector is provided with a sixth limiting part. By abutting against the fifth limiting part, the rotation of the balancing part around the axis of the inner cylinder can be restricted, reducing the possibility of the balancing part shifting during high-speed rotation.

[0080] Compared to the screw connection between the balance part and the inner tub in related technologies, the connection between the sixth limiting part and the fifth limiting part in some embodiments of this application has higher strength and can withstand greater tensile, shear, and impact forces. The abutting connection between the sixth and fifth limiting parts does not require additional connecting parts and will not loosen or be damaged due to insufficient or excessive torque during installation. Under conditions of excessive vibration or frequent impact, the abutting connection remains stable and is not easily loosened.

[0081] Therefore, in some embodiments of this application, the connection between the above-mentioned balancing part and the inner drum has strong stability and effectiveness, which can effectively reduce the vibration problem caused by the eccentricity of the inner drum, thereby improving the dehydration efficiency of the pulsator washing machine, reducing noise, and extending the service life of the pulsator washing machine.

[0082] Combination Figure 1 and Figure 2 As shown, some embodiments of this application provide a pulsator washing machine.

[0083] The pulsator washing machine includes a casing 10. The top of the casing 10 has a loading port 123 for loading clothes. The casing 10 includes a body 11 and a frame 12. The frame 12 surrounds the top of the body 11 and has the loading port 123 on it.

[0084] It should be noted that the chassis 10 has a left side wall 14 and a right side wall 15 arranged opposite to each other in the depth direction, and a front side and a rear side 13 arranged opposite to each other. The front side of the chassis 10 is the front side, which faces the Z direction in the figure. The rear side of the chassis 10 is the rear side 13, which faces away from the Z direction in the figure. The right side wall 15 of the chassis 10 faces the X direction in the figure, and the left side wall 14 of the chassis 10 faces away from the X direction in the figure.

[0085] Combination Figure 2As shown, in some embodiments, the pulsator washing machine also includes a door cover 40. The door cover 40 is located on the top of the casing 10 and can open or close the loading port 123. When the door cover 40 is open, it facilitates the user to load clothes into the loading port 123. When the door cover 40 is closed, it can cover the loading port 123 to enhance the safety of the pulsator washing machine during operation.

[0086] Combination Figure 2 As shown, in some embodiments, the pulsator washing machine also includes a drum assembly. The drum assembly is disposed inside the casing 10 and has a washing chamber 20. The drum opening of the drum assembly communicates with the washing chamber 20 and faces the loading port 123 so that clothes loaded through the loading port 123 can enter the washing chamber 20 for washing.

[0087] The cylinder assembly includes an outer cylinder. The outer cylinder is located inside the housing 11, and the opening of the outer cylinder faces the loading / unloading port.

[0088] The drum assembly includes an inner drum 200. The inner drum 200 is rotatably disposed inside the outer drum, and the opening of the inner drum 200 can also face the clothes loading / unloading opening. The opening of the inner drum 200 communicates with the washing chamber 20, so that the opening of the drum assembly communicates with the washing chamber 20. The inner drum 200 has a washing chamber 20. During the washing process, the inner drum 200 can rotate relative to the outer drum to wash the clothes in the washing chamber 20.

[0089] Multiple connecting holes can be provided on the wall of the inner cylinder 200. The connecting holes are used to connect the washing chamber 20 with the interior of the outer cylinder, so that the liquid in the washing chamber 20 can flow into the outer cylinder through the connecting holes and be discharged from the outer cylinder after washing.

[0090] It should be noted that the height direction of the inner cylinder 200 is in line with... Figure 1 The Y-axis is consistent.

[0091] To meet the demand for large-capacity washing in pulsator washing machines, the dimensions of the washing machine casing 10 and drum assembly (including the inner drum 200 and the outer drum) have been 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.

[0092] To improve user experience, combined with Figure 4 As shown, in some embodiments, a support portion 210 may be provided at the opening of the inner cylinder 200. The support portion 210 may be a flange provided at the opening of the inner cylinder 200. The support portion 210 extends away from the axis of the inner cylinder 200. The diameter of the end of the support portion 210 away from the axis of the inner cylinder 200 is larger than the diameter of the inner cylinder 200.

[0093] Combination Figure 5As shown, the opening of the inner cylinder 200 may also be provided with a riveting portion 240. The bottom end of the riveting portion 240 may be connected to the end of the supporting portion 210 opposite to the opening of the inner cylinder 200. The riveting portion 240 extends along the height direction of the inner cylinder 200. The riveting portion 240 may form a receiving area above the opening of the inner cylinder 200. The diameter of this receiving area is larger than the diameter of the inner cylinder 200.

[0094] For example, the balancing section 300 can be a balancing ring. The balancing ring can consist of an upper balancing section and a lower balancing section. The upper and lower balancing sections are connected by thermoforming to seal. The upper and lower balancing sections can be configured to form a cavity 320 for containing the balancing fluid.

[0095] Combination Figure 5 As shown, a protruding connector 310 may be provided on the periphery of the lower balancing part. The connector 310 may be integrally formed with the lower balancing part. The integrally formed lower balancing part and connector 310 have high connection strength, can withstand greater external forces and pressures, and help improve the connection stability between the balancing part 300 and the inner cylinder 200.

[0096] The connector 310 of the balancing part 300 can be connected to the riveting part 240. The balancing part 300 is fixed to the inner cylinder 200 by the connector 310, which can help balance the eccentric mass of the inner cylinder 200 and reduce vibration during rotation.

[0097] The inner diameter of the riveting part 240 can be larger than the outer diameter of the connector 310 so that the connector 310 can smoothly enter the receiving area enclosed by the riveting part 240 and realize the connection between the connector 310 and the riveting part 240.

[0098] The riveted part 240 can be connected to the connecting part 310 via a spin riveting process. It should be noted that spin riveting, also known as riveting or roll riveting, is a riveting process developed based on the principle of cold rolling. The spin riveting process mainly involves the eccentric rotation of the riveting head on a spin riveting machine, continuously rolling the circumference of the riveted part 240, thereby pressing the riveted part 240 onto the connecting part 310. Because spin riveting tightly connects the riveted part 240 and the connecting part 310 together through rolling, the connection is very strong. Furthermore, spin riveting does not create protrusions at the connection point, resulting in a more aesthetically pleasing appearance.

[0099] Understandably, if the gap between the riveting portion 240 and the connecting member 310 is too large, it will hinder the tight connection after riveting. If the gap between the riveting portion 240 and the connecting member 310 is too small, it will be difficult for the balancing portion 300 to enter the receiving area enclosed by the riveting portion 240. For example, the inner diameter of the riveting portion 240 can be 0.1 mm to 0.3 mm larger than the outer diameter of the connecting member 310. This facilitates the entry of the balancing portion 300 into the riveting portion 240 during processing and also facilitates the tight connection after riveting of the riveting portion 240 and the connecting member 310.

[0100] Combination Figure 6 As shown, the riveted portion 240 can form a connecting portion 220 after riveting. The connecting portion 220 is connected to the supporting portion 210 at its bottom along the height direction of the inner cylinder. The connecting portion 220 is disposed around the periphery of the connecting member 310. The connecting portion 220 abuts against the side of the connecting member 310. The connecting portion 220 can limit the connecting member 310 from its periphery, so that the balancing portion 300 and the inner cylinder 200 remain coaxial.

[0101] After riveting, a reinforcing portion 230 can be formed in part of the riveted portion 240. The reinforcing portion 230 is connected to the top of the connecting portion 220 along the height direction of the inner cylinder. The reinforcing portion 230 can be arranged perpendicularly to the connecting portion 220. The reinforcing portion 230 abuts against the top surface of the connector 310. The reinforcing portion 230, the bearing portion 210, and the connecting portion 220 can be configured to form a cavity that can accommodate the connector 310. The reinforcing portion 230 and the bearing portion 210 are distributed on both sides of the connector 310 along the height direction of the inner cylinder 200, which can support the balancing portion 300 in the height direction of the inner cylinder 200 and restrict the movement of the balancing portion 300 in the height direction of the inner cylinder 200.

[0102] In some embodiments, the connector 310 may be provided with a sixth limiting portion 311 along the axial direction of the balancing portion. The sixth limiting portion 311 may be provided on the side of the connector 310 facing the reinforcing portion 230.

[0103] As a riveting process, rotary riveting is highly adaptable, capable of accommodating the shape of the structure to be riveted, i.e., the connecting part 310. Combined with... Figure 6 As shown, during the riveting process, the fifth limiting part 231 can be formed at the position corresponding to the riveting part 240 and the sixth limiting part 311.

[0104] The fifth limiting part 231 is located on the side of the reinforcing part 230 facing the connector 310. The bearing part 210 and the fifth limiting part 231 are distributed on both sides of the connector 310 along the height direction of the inner cylinder 200. The bearing part 210 and the fifth limiting part 231 respectively abut against the two ends of the connector 310 along the height direction of the inner cylinder 200 to restrict the movement of the balancing part 300 along the height direction of the inner cylinder 200.

[0105] At least a portion of the fifth limiting part 231 abuts against the sixth limiting part 311. This locks the relative positions of the reinforcing part 230 and the connecting member 310. In addition to limiting the movement of the balancing part 300 along the height direction of the inner cylinder 200, the relative rotation of the reinforcing part 230 and the connecting member 310 is also effectively limited, thereby limiting the relative rotation of the balancing part 300 and the inner cylinder 200, achieving a stable connection between the balancing part 300 and the inner cylinder 200.

[0106] The fifth limiting part 231 and the sixth limiting part 311 abut against each other along the axial direction of the balancing part. The connection length between the fifth limiting part 231 and the sixth limiting part 311 can be set according to 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 part 231 and the sixth limiting part 311.

[0107] In some possible implementations, the balancing part 300 can be a plastic component comprising at least polypropylene. The plastic balancing part 300 is lightweight, flexible, and possesses good resistance to high and low temperatures and corrosion, meeting the usage requirements of pulsator washing machines in various environments.

[0108] In some embodiments, the balancing part 300 can be a plastic part comprising polypropylene and calcium carbonate. Adding calcium carbonate to polypropylene can significantly improve the material's rigidity, heat resistance, and dimensional stability. Furthermore, calcium carbonate is cheaper than polypropylene, and its addition can reduce the production cost of the balancing part 300, thus improving the product's cost-effectiveness.

[0109] For example, the plastic part can be made of polypropylene with more than 10% calcium carbonate. When the proportion of calcium carbonate in the polypropylene is more than 10%, the resulting plastic part can maintain good strength and toughness to withstand the forces generated by the washing machine during high-speed rotation. At the same time, the flexibility of polypropylene ensures that the plastic part is not easily broken or deformed when subjected to external forces.

[0110] Combination Figure 6 and Figure 7 As shown, in some possible embodiments, one of the fifth limiting part 231 and the sixth limiting part 311 can be a connector, and the other can be a protrusion. The protrusion passes through the connector. The combination of the connector and the protrusion is a simple and effective mechanical connection. The cooperation between the connector and the protrusion enables a quick and reliable connection, ensuring the stability of the balance part 300 on the inner cylinder 200. The protrusion, passing through the connector, provides a fixed connection point, enabling a self-locking function and restricting the rotation and movement of the balance part 300 along the axial direction of the inner cylinder 200.

[0111] Combination Figure 7As shown, in some possible embodiments, the sixth limiting part 311 can be configured as a protrusion. The protrusion can be integrally formed with the connector 310. For example, it can be integrally formed during injection molding or machining. The integrally formed protrusion and connector 310 have higher connection strength, the protrusion can withstand greater external forces, and the connection effectiveness can be improved, effectively limiting the relative rotation between the balancing part 300 and the inner cylinder 200.

[0112] The fifth limiting part 231 can be configured as a plug-in interface. During the riveting process, the position of the riveting part 240 corresponding to the protrusion can be press-formed to form a plug-in interface with an opening facing the protrusion. The opening shape of the plug-in interface matches the edge contour of the protrusion.

[0113] The protrusion can protrude upward along the height direction of the inner cylinder 200. The protrusion passes through the insertion interface. By inserting the protrusion into the insertion interface, a stable mechanical connection can be formed, effectively restricting the relative movement between the connector 310 and the fifth limiting part 231, thereby restricting the rotation of the balancing part 300 around the axis of the inner cylinder 200 and improving the connection stability between the balancing part 300 and the inner cylinder 200.

[0114] Combination Figure 6 As shown, in some other possible embodiments, the sixth limiting part 311 may be provided with a plug-in interface. The plug-in interface 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. As a receiving structure, the plug-in interface can accommodate the fifth limiting part 231 and provides a fixing point so that the balancing part 300 can be securely mounted on the inner cylinder 200.

[0115] The fifth limiting part 231 can be configured as a protrusion. During the riveting process, the riveting part 240 is pressed at the position corresponding to the insertion interface to form a protrusion facing the insertion interface. The edge contour of the protrusion matches the opening shape of the insertion interface. The protrusion is simple to form, and the fit between the protrusion and the insertion interface is tight after forming, which can improve the connection effectiveness. After the riveting part 240 and the connector 310 are riveted together, the formed reinforcing part 230 abuts against the upper surface of the connector 310 along the height direction of the inner cylinder 200, so as to tightly abut against the connector 310.

[0116] The protrusion can protrude downwards along the height direction of the inner cylinder 200. The protrusion passes through the insertion interface. By inserting the protrusion into the insertion interface, a stable mechanical connection can be formed, effectively limiting the relative movement between the connector 310 and the fifth limiting part 231, thereby limiting the rotation of the balancing part 300 around the axis of the inner cylinder 200 and improving the connection stability between the balancing part 300 and the inner cylinder 200.

[0117] Combination Figure 8 and Figure 9As shown, in some possible embodiments, the number of sixth limiting portions 311 can be multiple. The number of fifth limiting portions 231 can also be multiple. The fifth limiting portions 231 and the sixth limiting portions 311 are correspondingly arranged. After the multiple fifth limiting portions 231 and the sixth limiting portions 311 abut against each other, multiple connection points can be formed in the circumferential direction of the balancing portion 300. Multiple connection points can distribute the stress during rotation, reducing the load on individual connection points. Multiple connection points can provide more stable support, preventing loosening and displacement of the balancing portion 300. Especially under high-speed rotation and vibration conditions, the reliability of the connection can be effectively improved.

[0118] Multiple sixth limiting parts 311 are arranged sequentially at intervals along the circumference of the balancing part 300. The spaced-out arrangement of the sixth limiting parts 311 allows the connection points to be dispersed along the axial direction of the balancing part 300, thereby achieving all-round support for the balancing part 300. This design can effectively counteract the centrifugal force and unbalanced force generated during rotation, improving the stability of the washing machine.

[0119] In some embodiments, the plurality of sixth limiting portions 311 can be divided into multiple 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 in each group can provide more stable support.

[0120] In other embodiments, multiple sixth limiting portions 311 are arranged at equal intervals along the circumference of the balancing portion 300. This arrangement ensures that the limiting portions are distributed around the balancing portion 300, forming support points in various directions, thereby providing better support and restraint, reducing the possibility of uneven force distribution at various connection points, and achieving all-round support for the balancing portion 300. The equally spaced sixth limiting portions 311 make the design process more standardized and simplified, and also simplify the manufacturing process, thereby improving production efficiency and reducing costs.

[0121] In some possible implementations, the number of fifth limiting parts 231 and the number of sixth limiting parts 311 may be equal to 6.

[0122] Understandably, when the number of fifth limiting parts 231 and sixth limiting parts 311 is less than six, the number of connection points available after connection is limited. This results in greater impact forces on the fifth limiting parts 231 and sixth limiting parts 311 at each connection point, easily causing overload or wear on the fifth limiting parts 231 and sixth limiting parts 311, thus affecting the service life of the pulsator washing machine. When the number of fifth limiting parts 231 and sixth limiting parts 311 is set to six, a relatively larger number of connection points can be provided, which can more effectively distribute the forces generated by the balance part 300 and the inner drum 200 during operation, helping to reduce overload or wear.

[0123] In other embodiments, the number of fifth limiting portions 231 and the number of sixth limiting portions 311 may be greater than six. A greater number of fifth limiting portions 231 and sixth limiting portions 311 provides more support points, helping to reduce vibration and imbalance caused by single-point support. Because the load is distributed, the wear on each limiting portion is also reduced, thereby extending the service life of the pulsator washing machine.

[0124] In some possible implementations, the length of the protrusion along the circumference of the inner cylinder 200 may be equal to 15 millimeters.

[0125] Understandably, when the length of the protrusion is less than 15 mm, the contact area between the protrusion and the connector is small, which can easily lead to low connection strength between the protrusion and the connector. Especially as the size of the washing machine increases, the eccentricity and vibration of the inner drum 200 also increase. Insufficient connection strength between the protrusion and the connector can more easily affect the performance and stability of the balance part 300.

[0126] By setting the length of the protrusion to 15mm, sufficient support can be provided in the circumferential direction, reducing the impact of shear stress caused by rotation on the connection.

[0127] In some embodiments, the length of the protrusion along the circumference of the inner cylinder 200 may be greater than 15 mm. A longer protrusion results in greater strength, thereby enhancing the connection strength between the insertion interface and the protrusion. This helps to better resist circumferential shear forces during rotation.

[0128] Combination Figure 9 As shown, correspondingly, if the protrusion can be inserted into the connector, the length L1 of the connector opening can be greater than 15 mm. This length ensures that the protrusion can be smoothly connected to the connector and provides an effective contact area.

[0129] In some possible implementations, the width of the protrusion along the radial direction of the inner cylinder 200 may be equal to 5 mm.

[0130] Understandably, when the width of the protrusion is less than 5 mm, the contact area in the radial direction of the inner cylinder 200 is small after the protrusion is connected to the insertion interface, which will affect its rigidity and stability in the radial direction.

[0131] In mechanical connections, increasing the contact area is an effective way to improve connection strength. Increasing the width of the protrusion can increase its contact area. By setting the width of the protrusion to 5 mm, its radial rigidity and stability can be guaranteed, preventing bending or deformation during high-speed rotation.

[0132] In some embodiments, the width of the protrusion along the radial direction of the inner cylinder 200 may be greater than 5 mm. The increased width means that the protrusion has higher bending resistance in the radial direction, which helps to maintain the stability of the connection during rotation and prevents deformation due to centrifugal force.

[0133] In some possible implementations, the height of the protrusion along the height direction of the inner cylinder 200 may be greater than or equal to 3 mm.

[0134] Understandably, when the height of the protrusion is less than 3 mm, it is difficult to ensure that the protrusion can be effectively inserted into the interface, which is not conducive to achieving a reliable mechanical connection and providing sufficient restraint.

[0135] The height setting needs to ensure that the protrusion can achieve a self-locking function within the connector to prevent loosening under vibration or external force. By setting the height of the protrusion to be equal to or greater than 3 mm, it is possible to ensure that the protrusion can be effectively inserted into the connector, increasing the effective insertion length, providing better restraint, and ensuring the stability of the balance part 300.

[0136] Combination Figure 5 As shown, in some possible implementations, the height H of the connector 310 along the height direction of the inner cylinder 200 can be greater than or equal to 3 mm.

[0137] Understandably, the two ends of the connector 310 in the height direction abut against the bearing part 210 and the fifth limiting part 231, respectively, to restrict the movement of the balance part 300 along the height direction of the inner cylinder 200. If the height H of the connector 310 is less than 3 mm, the connector 310 will have insufficient bending resistance along the height direction of the inner cylinder 200, and is prone to breakage failure.

[0138] In mechanical connections, increasing the height can improve the rigidity and stability of the structure. A taller connector 310 can provide stronger support in the height direction to resist the effects of the gravity of the balancing part 300 and other stresses generated by the rotation of the balancing part 300 on the connection. By setting the height H of the connector 310 to be greater than or equal to 3 mm, greater support force can be provided, thereby enhancing the stability and vibration resistance of the connection.

[0139] Combination Figure 10 As shown, when the sixth limiting part 311 is configured as an insertion interface, the depth of the insertion interface can be equal to the height H of the connector 310, that is, the insertion interface 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 better limiting effect, and ensure the stability of the balance part 300.

[0140] Combination Figure 5As shown, in some possible embodiments, the width L2 of the connector 310 along the radial direction of the inner cylinder 200 can be greater than or equal to 5 mm.

[0141] Understandably, the two ends of the connector 310 in the height direction abut against the support portion 210 and the fifth limiting portion 231, respectively. When the width of the connector 310 is less than 5 mm, the contact area between the two ends of the connector 310 in the height direction and the support portion 210 and the fifth limiting portion 231 is small. This reduces the supporting and limiting effect of the support portion 210 and the fifth limiting portion 231 on the connector 310, making the connector 310 prone to movement along the height direction of the inner cylinder 200. By setting the width L2 of the connector 310 to be greater than or equal to 5 mm, the contact area between the connector 310 and the support portion 210 and the fifth limiting portion 231 can be effectively increased, improving the connection stability between the balance portion 300 and the inner cylinder 200.
