[0047] A washing machine is a household appliance used to wash clothes. Common washing machines include drum washing machines and pulsator washing machines. In order to reduce vibration, both drum washing machines and pulsator washing machines are provided with a balancing ring. For the convenience of description, the pulsator washing machine is used as an example for the following description.
[0048] Taking a pulsator washing machine as an example, the working principle of a pulsator washing machine is to rely on the forward and reverse rotation of the pulsator installed at the bottom of the washing drum, driving the clothes to flip up and down and left and right continuously, so that the clothes and the clothes and the drum wall are gently rubbed in the water, achieving the effect of decontamination and cleaning under the action of detergent.
[0049] In the prior art, in order to reduce the vibration caused by the eccentricity of the clothes, a balance ring is usually installed around the drum of the washing machine, and the balance ring is filled with a balance medium. When the drum rotates at high speed, the balance medium in the balance ring will automatically adjust its position under the action of centrifugal force to offset the eccentric force caused by the imbalance of the clothes, thereby reducing vibration. This can not only extend the service life of the washing machine, but also improve the operating stability and quietness of the washing machine.
[0050] At present, the balancing ring includes a shell, a partition and a balancing medium. The shell has an annular cavity. The partition is arranged in the annular cavity, and a liquid hole is formed between the partition and the shell, and the balancing medium flows in the annular cavity.
[0051] During the drying process of the washing machine, the speed of the drum is different in the early and middle stages of the drying process. In the low-speed dehydration stage of the washing machine, the water content of the clothes is large and the eccentricity is large. If the balance ring cannot work faster, the washing machine will vibrate more for a longer time; that is, in the low-speed dehydration stage of the washing machine, the balancing medium in the balance ring needs to move quickly. In the high-speed dehydration stage of the washing machine, the washing machine will shake periodically and generate noise due to the excessive size of the liquid hole. In other words, the flow rate requirements of the balancing medium in the balance ring are different in the early and middle stages of the drying process, and the balancing medium with different flow rates has different effects on reducing the vibration of the washing machine. At this stage, when the size of the partition is determined, the size of the liquid hole formed between the partition and the shell is determined. The liquid hole of fixed size cannot effectively adjust the flow rate of the balancing medium.
[0052] Therefore, the existing balancing ring has the problem of poor use effect.
[0053] In view of this, an embodiment of the present application provides a washing machine. The washing machine includes a body, a drum and a balancing ring. The body has a accommodating cavity. The drum is located in the accommodating cavity. The balancing ring is arranged at the barrel mouth of the drum. The balancing ring includes a shell, a shielding member and an adjusting assembly. The shell is connected to the barrel mouth of the drum. The shell has at least one annular cavity. The adjusting assembly and the shielding member are both located in the annular cavity. At least part of the shielding member is connected to the inner circumferential wall of the shell. There is a gap between at least part of the shielding member and the inner circumferential wall of the shell. The gap forms a liquid passage hole. The shielding member has a groove. The groove is connected to the liquid passage hole. When the drum rotates in a first speed range, the adjusting assembly is located in the groove. When the drum rotates in a second speed range, the adjusting assembly moves in a direction away from the groove and close to the liquid passage hole. The first speed range is smaller than the second speed range. The present application sets an adjustment component. When the washing machine rotates at different speeds, the adjustment component can move in the gap formed between the baffle and the inner wall of the shell, thereby adjusting the size of the liquid hole. In this way, the liquid hole can adjust the flow rate of the balancing medium located in the annular cavity of the balancing ring. Adjusting the flow rate of the balancing medium can change its distribution in the balancing ring. By controlling the flow rate of the balancing medium, balancing failure caused by excessive flow can be avoided, thereby improving the performance of the balancing ring and reducing the vibration of the washing machine.

[0061] Figure 1 The structural diagram of the washing machine provided in the embodiment of the present application is schematically shown. Figure 2 A schematic diagram schematically shows the structure of a balance ring 300 of a washing machine provided in an embodiment of the present application from a first perspective. Figure 3 The schematic diagram schematically shows the structure of the balance ring 300 of the washing machine provided in the embodiment of the present application from a second viewing angle. Figure 4 The schematic diagram schematically shows the structure of the balance ring 300 of the washing machine provided in the embodiment of the present application from a third viewing angle. Figure 5 The schematic diagram of the exploded structure of the balance ring 300 of the washing machine provided in the embodiment of the present application is schematically shown.
[0062] The present application embodiment provides a washing machine. Figures 1 to 5 As shown, the washing machine includes a body 100, a barrel 200 and a balance ring 300. The body 100 has a receiving cavity. The barrel 200 is located in the receiving cavity. The balance ring 300 is arranged at the barrel mouth of the barrel 200. The balance ring 300 includes a shell 310, a shielding member 320, and an adjustment assembly 330. The shell 310 is connected to the barrel mouth of the barrel 200. The shell 310 has at least one annular cavity. The adjustment assembly 330 and the shielding member 320 are both located in the annular cavity.
[0063] At least part of the shielding member 320 is connected to the inner peripheral wall of the housing 310. There is a gap between at least part of the shielding member 320 and the inner peripheral wall of the housing 310. The gap forms a liquid hole. The shielding member 320 has a groove. The groove is connected to the liquid hole.
[0064] When the cylinder 200 rotates in the first speed range, the adjustment component 330 is located in the groove. When the cylinder 200 rotates in the second speed range, the adjustment component 330 moves away from the groove and closer to the liquid passage hole. The first speed range is smaller than the second speed range.
[0065] In some embodiments, when the cylinder 200 rotates at a low speed (i.e., the first speed interval), the adjustment assembly 330 is located in the groove of the shielding member 320. At this time, the cross-sectional area of the liquid hole is the largest, which is conducive to the rapid flow of the balancing medium in the annular cavity, so that the balancing medium in the balancing ring 300 can quickly flow to the deviation correction position.
[0066] In other embodiments, when the drum 200 enters the high-speed rotation stage (i.e., the second speed interval), the centrifugal force on the balancing medium increases significantly. At this time, under the action of the centrifugal force, the adjustment component 330 moves away from the groove and toward the liquid hole. At this time, the cross-sectional area of the liquid hole decreases. When the drum 200 rotates at a high speed, the position of the balancing medium is basically in a stable state. By reducing the size of the liquid hole, the flow of the balancing medium can be suppressed, the stability of the balancing medium can be improved, and the vibration of the washing machine can be reduced.
[0067] The present application sets an adjustment component 330. When the drum 200 of the washing machine rotates in different speed ranges, the adjustment component 330 can move in the gap formed between the shielding member 320 and the inner wall of the shell 310, thereby adjusting the size of the liquid hole. In this way, the liquid hole can adjust the flow rate of the balancing medium located in the annular cavity of the balancing ring 300. Adjusting the flow rate of the balancing medium can change its distribution in the balancing ring 300. By controlling the flow rate of the balancing medium, balancing failure caused by excessive flow can be avoided, thereby improving the performance of the balancing ring and reducing the vibration of the washing machine.
[0068] Exemplarily, the equilibration medium may be saline or water.
[0069] Figure 6 The structure of the second housing 312 of the balance ring 300 of the washing machine provided in the embodiment of the present application is schematically shown. Figure 1 . Figure 7 The structure of the second housing 312 of the balance ring 300 of the washing machine provided in the embodiment of the present application is schematically shown. Figure 2 .
[0070] As a feasible implementation method, refer to Figures 5 to 7As shown, the housing 310 includes a first annular cavity 313 and a second annular cavity 314 which are not connected to each other. The first annular cavity 313 and the second annular cavity 314 are sequentially arranged along the direction from the center of the cylinder 200 to the outer periphery of the cylinder 200.
[0071] There are multiple adjustment components 330 , and the multiple adjustment components 330 are respectively located in the first annular cavity 313 and the second annular cavity 314 .
[0072] Exemplarily, the housing 310 includes a first housing 311 and a second housing 312. The first housing 311 has two annular grooves opening downward. The second housing 312 has two annular grooves opening upward. The first housing 311 and the second housing 312 are engaged with each other to form a first annular cavity 313 and a second annular cavity 314.
[0073] It can be understood that the first shell 311 is located on the top of the second shell 312 .
[0074] For example, by providing a first annular cavity 313 and a second annular cavity 314 that are not connected to each other, the first annular cavity 313 and the second annular cavity 314 are sequentially arranged from the center to the periphery of the drum 200, so that the area covered by the balance ring 300 of the drum 200 is increased, the balance ring 300 can be more comprehensively distributed in different areas of the drum 200, the balance ring 300 can effectively absorb and alleviate the vibration of the drum 200, provide a better vibration reduction effect, and improve the overall balance effect of the balance ring 300. Since the balance ring 300 covers a larger area of the drum 200 and the adjustment components 330 are distributed in different annular cavities, the balance ring 300 can effectively adjust the eccentricity of the clothes in the drum 200 and improve the overall balance effect of the balance ring. This helps to reduce the imbalance of the drum 200 when it rotates at high speed and improve the operating stability of the washing machine.
[0075] By setting a plurality of adjustment components 330 in the first annular cavity 313 and a plurality of adjustment components 330 in the second annular cavity 314, during the high-speed (i.e., second speed range) rotation of the drum 200, the adjustment components 330 in the first annular cavity 313 and the second annular cavity 314 work together, and the adjustment components 330 adjust the size of the liquid hole. In this way, the liquid hole can adjust the flow rate of the balancing medium located in the annular cavity of the balancing ring 300. Adjusting the flow rate of the balancing medium can change its distribution in the balancing ring 300. By controlling the flow rate of the balancing medium, balancing failure caused by excessive flow is avoided, thereby improving the performance of the balancing ring 300, improving the operating stability of the washing machine, and reducing vibration and noise.
[0076] For example, the size and position of the first annular cavity 313 and the second annular cavity 314 can be adjusted according to the specific requirements of the washing machine, as well as the number and type of the adjustment components 330. In this way, the balance ring 300 provided by the present application can be applied to washing machines of different models and specifications, and has strong adaptability.
[0077] Figure 8 The structural diagram of the adjustment component 330 of the balance ring 300 of the washing machine provided in an embodiment of the present application is schematically shown. Fig. 9 The structure of the housing 310 and the adjustment assembly 330 of the balancing ring 300 of the washing machine provided in the embodiment of the present application is schematically shown. Figure 1 . Fig.10 The structure of the housing 310 and the adjustment assembly 330 of the balancing ring 300 of the washing machine provided in the embodiment of the present application is schematically shown. Figure 2 .
[0078] As a feasible implementation method, refer to Figures 8 to 10 As shown, the adjustment assembly 330 includes an elastic member 331 and a moving member 332 connected to each other. The elastic member 331 is connected to the shielding member 320 .
[0079] When the cylinder 200 rotates in the first speed range, the moving member 332 is located in the groove. The moving member 332 abuts against the bottom wall of the groove. When the cylinder 200 rotates in the second speed range, the moving member 332 moves away from the groove and toward the liquid passage hole. At least part of the moving member 332 is located in the liquid passage hole.
[0080] In some embodiments, when the cylinder 200 rotates in the first speed range, the centrifugal force on the moving member 332 is small, and the moving member 332 is kept in the groove by its own gravity and the pulling force of the elastic member 331. At this time, the moving member 332 abuts against the bottom wall of the groove, and the balancing medium flows normally through the liquid hole.
[0081] In other embodiments, when the cylinder 200 rotates in the second speed range, the centrifugal force on the moving member 332 increases significantly, and the moving member 332 overcomes the elastic force of the elasticity under the action of the centrifugal force, moves out of the groove, and moves toward the direction close to the liquid hole. When the moving member 332 enters the liquid hole, it will block the liquid hole, reduce the cross-sectional area of the liquid hole, and hinder the flow of the balancing medium. By reducing the cross-sectional area of the liquid hole through the moving member 332, the balancing medium is closer to the inner wall of the shell 310, and the weight distribution of the balance ring 300 is more uniform, which helps to optimize the balance state of the cylinder 200.
[0082] Exemplarily, the elastic member 331 includes a spring.
[0083] As a feasible embodiment, the moving member 332 and the shielding member 320 are slidably connected. In this way, by arranging the moving member 332 and the shielding member 320 as a slidable connection, the moving member 332 moves smoothly when subjected to the centrifugal force. This smooth transition can reduce the impact and vibration of the moving member 332, and improve the running stability of the balance ring 300. At the same time, this sliding connection mode makes the position change of the moving member 332 in different speed intervals smoother, and optimizes the balance state of the cylinder 200.
[0084] As an achievable implementation, the adjustment assembly 330 further includes a fixing member 333 . A first end of the fixing member 333 is connected to the shielding member 320 . A second end of the fixing member 333 is connected to a first end of the elastic member 331 . A second end of the elastic member 331 is connected to the moving member 332 .
[0085] By setting the fixing member 333, the fixing member 333 connects the elastic member 331 and the shielding member 320, thereby improving the connection strength between the elastic member 331 and the shielding member 320, avoiding the elastic member 331 and the shielding member 320 from separating under the action of centrifugal force during the rapid rotation of the cylinder 200, and improving the service life of the balance ring 300.
[0086] Exemplarily, the fixing member 333 may be a fixing block.
[0087] As a feasible implementation, the moving member 332 includes a moving block 332a and a moving rod 332b.
[0088] The shielding member 320 has a cavity. The cavity is connected to the groove. The opening of the cavity is located on the bottom wall of the groove. At least part of the moving rod 332b is located in the cavity.
[0089] When the barrel 200 rotates in the first speed range, the moving rod 332b is located in the cavity. The moving block 332a is located in the groove. When the barrel 200 rotates in the second speed range, the moving block 332a moves away from the groove and toward the liquid passage hole. At least part of the moving block 332a is located in the liquid passage hole. The moving block 332a drives the moving rod 332b to move toward the opening direction of the cavity.
[0090] Exemplarily, the combined design of the moving block 332a and the moving rod 332b allows the moving member 332 to move smoothly when subjected to an external force (such as centrifugal force).
[0091] When the cylinder 200 rotates in the second speed range, the centrifugal force on the moving block 332a increases, and the moving block 332a overcomes the elastic force of the elastic member 331 under the action of the centrifugal force, slides out of the groove, and moves toward the direction close to the liquid hole. At least part of the moving block 332a is located in the liquid hole to change the size of the liquid hole, thereby changing the flow path and flow speed of the balancing medium.
[0092] For example, by setting a cavity in the shielding member 320, the moving block 332a drives the moving rod 332b to move toward the opening direction of the cavity. Since the moving rod 332b can only move along the extension direction of the cavity, this limits the moving direction of the moving block 332a, ensuring that it can only move on a predetermined path. The design of limiting the moving direction enables the moving block 332a to move smoothly when subjected to external forces (such as centrifugal force), reduces unnecessary swings and offsets, and further improves the accuracy of the balance adjustment.
[0093] As an achievable implementation, there is a gap between the first end of the shielding member 320 and the housing 310. There is a gap between the second end of the shielding member 320 and the housing 310.
[0094] The direction from the first end of the shielding member 320 to the second end of the shielding member 320 is parallel to the radial direction of the cylinder 200 .
[0095] The first end of the shielding member 320 and the inner circumferential wall of the housing 310 form a first liquid-passing hole 321, and the second end of the shielding member 320 and the inner circumferential wall of the housing 310 form a second liquid-passing hole 322. In this way, when the drum 200 rotates at different speeds, by arranging the first liquid-passing hole 321 and the second liquid-passing hole 322 at different positions, the flow path of the balancing medium can be optimized to reduce vibration for the washing machine.
[0096] Exemplarily, the shielding member 320 may be a shielding plate having a certain thickness.
[0097] As an achievable implementation, the groove is communicated with the second liquid passage hole 322 , and the notch of the groove faces the second liquid passage hole 322 .
[0098] When the cylinder 200 rotates in the first speed range, the moving member 332 is located in the groove. When the cylinder 200 rotates in the second speed range, the moving member 332 leaves the groove and moves toward the second liquid passage hole 322.
[0099] Exemplarily, the regulating assembly 330 is located in the second liquid passage hole 322 .
[0100] In some embodiments, when the cylinder 200 rotates in the first speed range, the adjustment component 330 is kept in the groove of the shielding member 320 due to gravity or a small centrifugal force. In this stage, the balancing medium flows in the annular cavity through the first liquid hole 321 and the second liquid hole 322, but because the position of the adjustment component 330 is relatively fixed, the liquid flows more smoothly and the vibration is small.
[0101] In other embodiments, when the drum 200 rotates in the second speed range, the centrifugal force on the adjustment component 330 increases significantly, and the adjustment component 330 moves from the groove under the action of the centrifugal force, and moves toward the second liquid-passing hole 322. Due to the movement of the adjustment component 330, the flow path of the balancing medium changes, and the flow amount of the balancing medium through the second liquid-passing hole 322 decreases. In this way, the liquid-passing hole can adjust the flow rate of the balancing medium in the annular cavity of the balancing ring 300. Adjusting the flow rate of the balancing medium can change its distribution in the balancing ring 300. By controlling the flow rate of the balancing medium, the balancing failure caused by too fast flow is avoided, thereby improving the use performance of the balancing ring 300 and reducing the vibration of the washing machine.
[0102] As a feasible implementation, along a direction perpendicular to the first end of the shielding member 320 to the second end of the shielding member 320 , the cross-sectional area of the first liquid passage hole 321 is greater than the cross-sectional area of the second liquid passage hole 322 .
[0103] In some embodiments, when the cylinder 200 rotates in the first speed range, the centrifugal force is small, and the balancing medium mainly flows through the first liquid hole 321. Since the cross-sectional area of the first liquid hole 321 is large, the balancing medium can flow through the first liquid hole 321 more freely, providing a moderate vibration reduction effect.
[0104] In other embodiments, when the drum 200 enters the second speed range and rotates, the centrifugal force increases significantly, and the moving block 332a overcomes the elastic force of the elastic member 331 under the action of the centrifugal force, slides out of the groove, and moves toward the direction close to the liquid passage hole. At least part of the moving block 332a enters the second liquid passage hole 322, changing the flow path of the liquid. Since the cross-sectional area of the second liquid passage hole 322 is small, the smaller size of the second liquid passage hole 322 can suppress the flow of the balancing medium and reduce the vibration of the washing machine.
[0105] For example, since the first liquid hole 321 is located close to the rotation center of the cylinder 200, the flow rate of the balancing medium at the first liquid hole 321 is relatively low. The larger cross-sectional area of the first liquid hole 321 can reduce the flow resistance of the balancing medium, allowing more balancing medium to pass through, thereby quickly responding to the eccentricity change of the cylinder. The second liquid hole 322 is located away from the rotation center of the cylinder 200, and the flow rate of the balancing medium at the second liquid hole 322 is relatively high. The smaller cross-sectional area of the second liquid hole 322 can increase the flow resistance of the balancing medium, control the flow speed of the balancing medium, and avoid balancing failure caused by excessive flow.
[0106] By providing liquid holes with different cross-sectional areas in the shielding member 320, an optimized liquid flow path and vibration reduction effect in different speed ranges are achieved. The larger first liquid hole 321 provides a moderate vibration reduction effect at low speed rotation, while the smaller second liquid hole 322 provides a stronger vibration reduction effect at high speed rotation, thereby achieving precise balance adjustment.
[0107] The embodiment of the present application provides a washing machine, comprising a machine body 100, a drum 200 and a balancing ring 300. The machine body 100 has a receiving cavity. The drum 200 is located in the receiving cavity. The balancing ring 300 is used to be arranged at the barrel mouth of the drum 200. The balancing ring 300 includes a shell 310, a shielding member 320, and an adjustment assembly 330. The shell 310 has at least one annular cavity. The adjustment assembly 330 and the shielding member 320 are both located in the annular cavity.
[0108] At least a portion of the shielding member 320 is connected to the inner peripheral wall of the housing 310. A gap is provided between at least a portion of the shielding member 320 and the inner peripheral wall of the housing 310. The gap forms a liquid passage hole.
[0109] When the cylinder 200 rotates in the first speed range, the adjustment component 330 is used to abut against the shielding member 320. When the cylinder 200 rotates in the second speed range, the adjustment component 330 is used to move away from the shielding member 320 and close to the liquid hole. The first speed range is smaller than the second speed range.
[0110] The present application sets an adjustment component 330. When the washing machine rotates at different speeds, the movable part 332 in the adjustment component 330 can move in the gap formed between the shielding part 320 and the inner wall of the shell 310, thereby adjusting the size of the liquid hole. In this way, the liquid hole can adjust the flow rate of the balancing medium located in the annular cavity of the balancing ring 300, control the flow rate of the balancing medium, avoid balancing failure caused by too fast flow, and thus improve the performance of the balancing ring 300 and reduce the vibration of the washing machine.
