Description

Technical Field

[0001] The invention belongs to the technical field of washing equipment, and in particular relates to a suspension rod assembly of washing equipment and a washing equipment having the suspension rod assembly. Background Art

[0002] The structure of an existing fully automatic washing machine includes: a shell forming the appearance of the washing machine; an outer barrel suspended and fixed by a supporting member and used to contain washing water is provided inside the shell; an inner barrel rotatably installed inside the outer barrel and provided with an agitator at the bottom; a driving motor installed on the lower side of the outer barrel and used to generate driving force for the agitator and the inner barrel; a power transmission device for selectively providing the driving force of the driving motor to the agitator and the inner barrel; a drainage device installed at the lower part of the outer barrel and used to discharge the washing water contained in the outer barrel to the outside, and four hanging ears are provided on the outer barrel, which is suspended on the shell through a suspension rod assembly.

[0003] At present, the suspension rod assembly includes a suspension rod, a suspension rod seat, a ball seat, a spring and a spring seat. The suspension rod seat is arranged at the top of the suspension rod, and the spring seat, the spring and the ball seat are successively passed through the suspension rod from the bottom end of the suspension rod upward, and a friction plate is sleeved inside the ball seat; a spherical groove is arranged on the washing machine shell, and the convex spherical surface of the suspension rod seat cooperates with the spherical groove on the shell; the bottom end of the outer barrel also has a spherical groove, and the convex spherical surface of the ball seat cooperates with the spherical groove at the bottom end of the outer barrel, so that the outer barrel is suspended on the washing machine shell.

[0004] When the washing machine is working, the vibration generated by the outer drum will cause the ball seat to move up and down. The ball seat then generates damping force through the expansion and contraction of the spring and the reciprocating friction between the friction plate and the suspension rod, thereby suppressing the vibration and achieving the purpose of improving the vibration and noise level of the whole machine.

[0005] During dehydration, the vibration-damping component at the lower end of the suspension rod assembly can reduce vibration and noise for the washing machine. However, the vibration-damping and noise-reducing effect of this type of vibration-damping component is not very good. Especially since the capacity of current washing machines is relatively large, when clothes are washed in the inner barrel of the washing machine, the clothes are very likely to be eccentric. During dehydration operation, especially when the clothes in the inner barrel are eccentric, the outer barrel will swing during operation. When the eccentricity of the clothes is large, the swing amplitude of the outer barrel will increase. When it exceeds the self-correction ability of the washing machine, the washing machine will automatically collide with the stop switch to stop the dehydration operation, or collide with the cabinet, resulting in abnormal noise.

[0006] In addition, the required shock-absorbing capabilities are different in different washing programs or washing water levels, resulting in that during the use of the current suspension assembly, the shock-absorbing effect is better for individual loads, but not for other loads, resulting in the overall vibration and noise of the washing machine being relatively large.

[0007] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0008] In view of the above-mentioned problems in the prior art, the present invention proposes a suspension rod assembly for washing equipment, wherein partitions and springs are arranged at intervals. The number of springs required for shock absorption can be selected according to different washing parameters, which is conducive to using the appropriate number of springs to achieve the best shock absorption effect.

[0009] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: A suspension rod assembly for a washing device, comprising: boom; A sleeve, which is sleeved on the suspension rod, and the bottom of the sleeve is fixedly arranged on the suspension rod; A partition plate is disposed in the sleeve and divides the space in the sleeve into a plurality of upper and lower partition spaces; A plurality of springs, each of which is located in the plurality of separation spaces; A barrel support, which is movably mounted on the suspension rod and abuts against the upper end of the uppermost spring; A locking structure, which is used to achieve locking between the partition and the sleeve; When the washing device is washing, the number of the springs required for shock absorption is determined according to the washing parameters; then the partitions between the springs involved in shock absorption are unlocked from the locking structure.

[0010] In some embodiments of the present application, the elastic coefficients of the multiple springs are different, and the elastic coefficients of the multiple springs increase sequentially from top to bottom.

[0011] In some embodiments of the present application, the locking structure has a movably disposed locking block on the sleeve, a locking groove opened on the partition and matched with the locking block, and a driving motor for driving the locking block to move to achieve locking and unlocking.

[0012] In some embodiments of the present application, step S100 of determining the number of springs required for shock absorption includes: S110. The washing device is powered on, and a washing program and a washing water level are selected; S120. According to the washing program and the washing water level, the preset pressure value Fa is obtained, Fa=10*K*P, K represents the water level value, and P represents the coefficient value corresponding to the washing program; S130. Compare the preset pressure value Fa with the pressure range formed by the maximum pressure values ​​that the multiple springs can withstand, and obtain the number of the springs required for shock absorption.

[0013] In some embodiments of the present application, the Nth spring is a plurality of springs whose position order from top to bottom is N, N is a natural number and N≥1; the Nth maximum pressure value is the sum of the maximum pressure values ​​that the Nth spring and all springs above it can withstand; the Nth pressure interval is between the N-1th maximum pressure value and the Nth maximum pressure value; the preset pressure value Fa is less than the Nth maximum pressure value; In step S130, if the preset pressure value Fa is in the Nth pressure interval, the number of springs required for shock absorption is N.

[0014] In some embodiments of the present application, each of the partitions is provided with the locking structure, and a pressure sensor is provided on the locking structure; when the partition is in a locked state, the pressure sensor is used to detect the pressure applied to the partition.

[0015] In some embodiments of the present application, during the water intake process of the washing device, when the pressure value fed back by the pressure sensor is greater than the locking pressure value, the locking structure is controlled to release the lock on the partition, so that the spring adjacent to the lower side of the partition participates in shock absorption; The locking pressure value is the sum of the maximum pressure value that the spring adjacent to the upper side of the partition can withstand multiplied by the corresponding protection coefficient and the maximum pressure value that all springs located above the spring can withstand.

[0016] In some embodiments of the present application, there is also a step S200 of determining the number of springs involved in shock absorption, including: S210. Determine the pressure interval in which the preset pressure value Fa is located. If the pressure interval is the first pressure interval, the number of springs involved in shock absorption is 1; if the pressure interval is the Nth pressure interval, and N≥2, proceed to step S220; or in other words, step S200 is only required when N≥2.

[0017] S220. Determine the locking pressure value corresponding to the Nth pressure interval; the pressure locking value corresponding to the Nth pressure interval is the sum of the maximum pressure value that the N-1th spring can withstand multiplied by the corresponding protection coefficient and the maximum pressure value that all springs located above the N-1th spring can withstand; S230. Compare the pressure value fed back by the pressure sensor at the partition adjacent to the upper side of the Nth spring with the corresponding locking pressure value. If the pressure value fed back by the pressure sensor is greater than the corresponding locking pressure value, determine that the number of springs participating in shock absorption is N; if the pressure value fed back by the pressure sensor is less than or equal to the corresponding locking pressure value, proceed to step S240; S240. Then determine whether the coefficient value P corresponding to the washing program is greater than or equal to 1. If so, determine that the number of springs involved in shock absorption is N; if not, determine that the number of springs involved in shock absorption is N-1.

[0018] In some embodiments of the present application, in step S200, when it is determined that the number of springs involved in shock absorption is N, control is performed to release the locking structure at the partition adjacent to the upper side of the Nth spring.

[0019] In some embodiments of the present application, step S140 is further included after step S130: S141. Determine whether the locking structure needs to be released; the number of springs required for shock absorption is N, determine whether N is greater than 2, if so, proceed to step S142; if not, there is no need to release the locking structure; S142. Unlock the locking structures at all the partitions above the N-1th spring.

[0020] Based on the above-mentioned suspension rod assembly of the washing equipment, the present invention also provides a washing equipment with the above-mentioned suspension rod assembly. The partitions and springs are arranged at intervals. The number of the springs required for shock absorption can be selected according to different washing parameters, which is conducive to using a suitable number of springs to achieve the best shock absorption effect.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are: the partitions and springs arranged at intervals in the sleeve are used for shock absorption, and the number of springs required for shock absorption can be selected according to different washing parameters. An appropriate number of springs is used for shock absorption, so that the generated vibration matches the shock absorption capacity to achieve the best shock absorption effect.

[0031] See also Figure 1-Figure 3, is an embodiment of a suspension rod assembly of a washing device proposed by the present invention, a suspension rod assembly 100 of a washing device comprises: a suspension rod 10, a sleeve 20, a barrel support 30, a partition 40, a spring 50, and a locking structure 60, wherein the sleeve 20 is sleeved on the suspension rod 10, the sleeve 20 is an open-top cylindrical shape, the bottom of the sleeve 20 is fixedly arranged with the lower end of the suspension rod 10, the barrel support 30 is sleeved on the suspension rod 10 and can move up and down, and the washing barrel assembly is pressed on the barrel support 30. The partition 40 is arranged in the sleeve 20, and the partition 40 is used to divide the space in the sleeve 20 into a plurality of upper and lower separation spaces; a plurality of springs 50 are respectively located in the plurality of separation spaces; that is, the springs 50 and the partition 40 are arranged at intervals in the upper and lower directions in the sleeve 20, the upper end of the uppermost spring 50 abuts against the barrel support 30, the barrel support 30 can extend into the sleeve 20, and the lower end of the lowermost spring 50 abuts against the bottom of the sleeve 20. The locking structure 60 is used to achieve locking between the partition 40 and the sleeve 20. After the locking structure 60 locks the partition 40, the spring 50 located below the partition 40 does not participate in shock absorption; after the locking structure 60 is unlocked, the partition 40 can move up and down in the sleeve 20 with the spring 50.

[0032] When the washing machine is washing, the number of springs 50 required for shock absorption is determined according to different washing parameters; then the partitions 40 between the springs 50 involved in shock absorption are unlocked by the locking structure 60, that is, the partitions 40 between the springs 50 involved in shock absorption can be moved up and down. The partitions 40 and springs 50 arranged at intervals in the sleeve 20 are used for shock absorption. The number of springs 50 required for shock absorption can be selected according to different washing parameters. The appropriate number of springs 50 is used for shock absorption, so that the generated vibration matches the shock absorption capacity and achieves the best shock absorption effect.

[0033] In some embodiments of the present application, the elastic coefficients of the multiple springs 50 are different, and the elastic coefficients of the multiple springs 50 increase from top to bottom. The top spring must participate in shock absorption, and the springs below can participate in shock absorption in sequence; by setting different shock absorption coefficients, the shock absorption support capacity of the multiple springs 50 is gradually enhanced.

[0034] In some embodiments of the present application, the locking structure 60 has a movably provided locking block 61 on the sleeve 20, a locking groove 62 provided on the partition 40, the locking groove 62 is matched with the locking block 61, and also has a driving motor 63 for driving the locking block 61 to move to achieve locking and unlocking. Under normal conditions, the locking structure 60 is in a locked state, and the locking block 61 is located in the locking groove 62, so that the partition 40 and the sleeve 20 are fixed. When it is necessary to unlock the locking structure 60, the driving motor 63 is controlled to start, and the locking block 61 is driven to move outward, so that the locking block 61 is disengaged from the locking groove 62, so that the partition 40 can be moved in the sleeve 20, so that the spring 50 adjacent to the lower side of the partition 40 participates in shock absorption.

[0035] In some embodiments of the present application, step S100 of determining the number of springs 50 required for shock absorption includes: S110. Power on the washing device, select the washing program and washing water level; The selection of the program can be manual or automatic, such as by installing a camera to identify the type of clothes put in and automatically select the program; the washing water level can also be automatically selected, such as by the weight of the clothes put in, or it can be manually selected.

[0036] S120. According to the washing program and the washing water level, the preset pressure value Fa is obtained, Fa=10*K*P, K represents the water level value, and P represents the coefficient value corresponding to the washing program; Through the washing program and washing water level in the washing parameters, the system can calculate the preset pressure value Fa. The preset pressure value Fa is set to predict the pressure that the suspension rod 10 needs to withstand during washing.

[0037] S130. Compare the preset pressure value Fa with the pressure interval formed by the maximum pressure value that the multiple springs 50 can withstand, and obtain the number of springs 50 required for shock absorption; In the order of using the multiple springs 50, they are used from top to bottom, and the multiple springs from top to bottom are defined as the first spring, the second spring, ..., the Nth spring, so the boundary value of the pressure range is set to the maximum pressure value that the first spring can withstand, the sum of the maximum pressure values ​​that the first spring and the second spring can withstand, ..., the sum of the maximum pressure values ​​that the Nth spring and all the springs above it can withstand. The number of springs 50 required for shock absorption can be inferred from which range the pressure preset value Fa belongs to.

[0038] In some embodiments of the present application, the Nth spring is a plurality of springs whose position order from top to bottom is N, N is a natural number and N≥1; the Nth maximum pressure value is the sum of the maximum pressure values ​​that the Nth spring and all springs thereon can withstand; the Nth pressure interval is between the N-1th maximum pressure value and the Nth maximum pressure value; the preset pressure value Fa is less than the Nth maximum pressure value; In step S130, if the preset pressure value Fa is in the Nth pressure interval, the number of springs required for shock absorption is N. The number of springs required for shock absorption inferred at this time is a theoretical inferred value, which may have an error with the actual value and needs to be further judged for accuracy; the accuracy judgment mainly depends on whether the Nth spring needs to participate in shock absorption, and the upper N-1 springs 50 will participate in shock absorption; therefore, the locking structure 60 corresponding to the partition 40 between the upper N-1 springs 50 controls unlocking.

[0039] Specifically, after step S130, there is also step S140: S141. Determine whether the locking structure 60 needs to be released; the number of springs 50 required for shock absorption is N, and determine whether N is greater than 2. If so, proceed to step S142; if not, there is no need to release the locking structure 60; Specifically, if the number of springs 50 required for shock absorption is 1, during the washing process, only one spring 50 is required to participate in shock absorption, that is, only the first spring participates in shock absorption, and all the partitions 40 are in a locked state; at this time, there is definitely no need to unlock the locking structure 60. If the number of springs 50 required for shock absorption is 2, it is theoretically inferred that the first spring and the second spring need to participate in shock absorption, but accuracy verification is still required, so it is uncertain whether the second spring participates in shock absorption, so at this time, the first partition between the first spring and the second spring cannot perform shock absorption. Only when the inferred number of springs 50 required for shock absorption is greater than 2, it is necessary to perform the unlocking operation in step S140.

[0040] S142. Release the lock of the locking structure 60 at all the partitions 40 above the N-1 spring; Specifically, each partition 40 is provided with a corresponding locking structure 60. The N-1th spring and the spring 50 above it will definitely participate in shock absorption. Therefore, after inferring the number of springs 50 required for shock absorption, the partition 40 that needs to be unlocked will be unlocked; there is no need for subsequent judgment, which is conducive to simplifying the process and improving efficiency.

[0041] In some embodiments of the present application, a pressure sensor is provided on the locking structure 60, and the pressure sensor is arranged on the locking block 61; when the partition 40 is in a locked state, the locking block 61 is located in the locking groove 62, and the pressure sensor is used to detect the pressure on the partition 40. Of course, after the partition 40 is unlocked, the locking block 61 moves out of the locking groove 62.

[0042] In some embodiments of the present application, a locking structure 60 is provided at each partition 40. When the pressure value fed back by the pressure sensor is greater than the locking pressure value during the water inlet process of the washing device, the locking structure 60 is controlled to release the lock of the partition 40, so that the spring 50 adjacent to the lower side of the partition 40 participates in the shock absorption. The pressure value fed back by the pressure sensor is the actual pressure on the partition 40, and the locking pressure value is the sum of the maximum pressure value that the spring 50 adjacent to the upper side of the partition 40 can withstand multiplied by the corresponding protection coefficient and the maximum pressure value that all springs above the spring 50 can withstand. The protection coefficient corresponding to each spring is different, and the maximum pressure value of the Nth spring is multiplied by the corresponding protection coefficient. First, the vibration of the washing bucket module is small during the water inlet stage, and second, before the Nth spring is compacted, the locking structure 60 is driven to move, so that the locking block 61 can smoothly disengage from the locking groove 62, which is convenient for the disengagement operation. By setting a pressure sensor, it is possible to judge whether the spring 50 adjacent to the lower side of the partition 40 needs to participate in the shock absorption according to the actual pressure on the partition 40. In this embodiment, only the actual pressure exerted on the partition 40 adjacent to the upper side of the Nth spring is determined, which is beneficial to simplifying the process, reducing the control judgment time, and improving efficiency.

[0043] In some other embodiments of the present application, the unlocking of each partition 40 can be set to be determined by the pressure value fed back by the pressure sensor.

[0044] In some embodiments of the present application, there is also a step S200 of determining the number of springs involved in shock absorption, which determines whether all the springs 50 required for shock absorption determined in step S100 participate in shock absorption, mainly whether the bottom spring 50 participates in shock absorption, that is, whether the Nth spring participates in shock absorption, where N≥2.

[0045] Wherein, step S200 includes: S210. Determine the pressure interval in which the preset pressure value Fa is located. If the pressure interval is the first pressure interval, the number of springs involved in shock absorption is 1; if the pressure interval is the Nth pressure interval, and N≥2, proceed to step S220; Specifically, the first spring must participate in shock absorption. When the weight of the washing tub assembly and the clothes, washing water, etc. inside the washing tub assembly is small during washing, only the first spring is needed for shock absorption. When it is determined that the number of springs participating in shock absorption is 1, it is directly confirmed that the number of springs participating in shock absorption is 1. When it is determined that the number of springs participating in shock absorption is N, and N ≥ 2, it is necessary to determine whether the Nth spring participates in shock absorption.

[0046] S220. Determine the locking pressure value corresponding to the Nth pressure interval; the pressure locking value corresponding to the Nth pressure interval is the sum of the maximum pressure value that the N-1th spring can withstand multiplied by the corresponding protection coefficient and the maximum pressure value that all springs located above the N-1th spring can withstand.

[0047] S230. Compare the pressure value fed back by the pressure sensor at the partition 40 adjacent to the upper side of the Nth spring with the corresponding locking pressure value; if the pressure value fed back by the pressure sensor is greater than the corresponding locking pressure value, determine that the number of springs participating in shock absorption is N; if the pressure value fed back by the pressure sensor is less than or equal to the corresponding locking pressure value, proceed to step S240; S240. Then determine whether the coefficient value P corresponding to the washing program is greater than or equal to 1. If so, determine that the number of springs 50 involved in shock absorption is N; if not, determine that the number of springs involved in shock absorption is N-1.

[0048] During the washing process of the washing equipment, different programs have different corresponding timings and speeds, and thus generate different powers. By judging whether the program coefficient P is greater than 1, the phenomenon of using small springs for vibration reduction with high power can be avoided. This is to enable programs with high speed and high power to match the appropriate number of springs for shock reduction, better reduce the shaking of the washing tub module, reduce the amplitude, reduce noise, and improve user experience and satisfaction.

[0049] In some embodiments of the present application, in step S200, when it is determined that the number of springs 50 participating in shock absorption is N, the locking structure 60 at the partition 40 adjacent to the upper side of the Nth spring is controlled to be released.

[0050] See also Figure 4 Taking three springs 50 and two partitions 40 as an example, the control method of the above-mentioned suspension rod assembly 100 is explained. The three springs 50 are respectively a first spring 51, a second spring 52, and a third spring 53 from top to bottom, and the two partitions 40 are respectively a first partition 41 and a second partition 42 from top to bottom. Correspondingly, a limiting structure 60 is provided at the first partition 41, and a limiting structure 60 is provided at the second partition 42.

[0051] The control method of the above-mentioned boom assembly 100 comprises the following steps: S100 determines the number of springs 50 required for shock absorption; S110. Power on the washing device, select the washing program and washing water level; The selection of the program can be manual or automatic, such as by installing a camera to identify the type of clothes put in and automatically select the program; the washing water level can also be automatically selected, such as by the weight of the clothes put in, or it can be manually selected.

[0052] S120. According to the washing program and the washing water level, the preset pressure value Fa is obtained, Fa=10*K*P, K represents the water level value, and P represents the coefficient value corresponding to the washing program; Through the washing program and washing water level in the washing parameters, the system can calculate the preset pressure value Fa. The preset pressure value Fa is set to predict the pressure that the suspension rod 10 needs to withstand during washing.

[0053] S130. Compare the preset pressure value Fa with the pressure interval formed by the maximum pressure value that the multiple springs 50 can withstand, and obtain the number of springs 50 required for shock absorption; In this embodiment, the maximum pressure value that the first spring 51 can withstand is Fmax1, the maximum pressure value that the second spring 52 can withstand is Fmax2, and the maximum pressure value that the third spring 53 can withstand is Fmax3; therefore, the first maximum pressure value is Fmax1, the second maximum pressure value is Fmax1+Fmax2, and the third maximum pressure value is Fmax1+Fmax2+Fmax3. The first pressure interval is greater than zero and less than or equal to the first maximum pressure value Fmax1, the second pressure interval is greater than the first maximum pressure value Fmax1 and less than or equal to the second maximum pressure value Fmax1+Fmax2; the third pressure interval is greater than the second maximum pressure value Fmax1+Fmax2 and less than or equal to the third maximum pressure value Fmax1+Fmax2+Fmax3. In step S130, the preset pressure value Fa is compared with each pressure interval in sequence, and the pressure interval where the preset pressure value Fa is located is found, and then the number of springs required for shock absorption can be determined.

[0054] After step S130, there is also step S140: S141. Determine whether the locking structure 60 needs to be released; whether the number of springs 50 required for shock absorption is greater than 2, if so, proceed to step S142; if not, there is no need to release the locking structure 60; Specifically, if the number of springs 50 required for shock absorption is 1, during the washing process, only one spring 50 is required to participate in shock absorption, that is, only the first spring participates in shock absorption, and all the partitions 40 are in a locked state; at this time, there is definitely no need to unlock the locking structure 60. If the number of springs 50 required for shock absorption is 2, it is theoretically inferred that the first spring and the second spring need to participate in shock absorption, but accuracy verification is still required, so it is uncertain whether the second spring participates in shock absorption, so at this time, the first partition between the first spring and the second spring cannot perform shock absorption. Only when the inferred number of springs 50 required for shock absorption is greater than 2, it is necessary to perform the unlocking operation in step S140.

[0055] S142. Release the lock of the locking structure 60 at all the partitions 40 above the second spring; that is, release the lock of the locking structure 60 at the first partition 41.

[0056] Step S200 determines the number of springs involved in shock absorption, including the following steps: S210. Determine the pressure interval in which the preset pressure value Fa is located. If the pressure interval is the first pressure interval, the number of springs involved in shock absorption is 1; if the pressure interval is the Nth pressure interval, and N≥2, proceed to step S220.

[0057] S220.
