Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and in particular, relates to a dehydration control method for washing equipment and the washing equipment. Background Art

[0002] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other programs, such as washing machines, washer-dryers, etc.

[0003] The dehydration process refers to the process of removing water from the clothes by rotating the drum containing the clothes and using centrifugal force. The distribution of clothes in the drum during the dehydration process is difficult to control. Clothes will be unevenly distributed in the drum due to knots or entanglements during the flipping process, resulting in eccentricity. This will cause the clothes and water to hit the drum wall back and forth. Especially when the water in the drum cannot be drained away in time, the washing machine will dehydrate with water, and the noise generated is particularly obvious, affecting the user experience.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a dehydration control method for a washing machine, so as to timely discharge the washing water removed during the dehydration process, effectively correct the eccentricity of the barrel, and reduce the dehydration noise. Another purpose of the present invention is to provide a washing machine, so as to achieve the purpose of reducing the noise generated during the dehydration process of the washing machine.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A dehydration control method for a washing device, the washing device comprising a barrel body. During the dehydration process, if the barrel body is eccentric, the barrel body rotation speed is controlled to rise and fall to correct the eccentricity, the eccentricity value of the barrel body is obtained, and the barrel body rotation speed is controlled to rise and fall according to the number of rise and fall times corresponding to the obtained eccentricity value.

[0008] Furthermore, the lifting times are controlled to be positively correlated with the acquired eccentricity value.

[0009] Furthermore, during the process of raising and lowering the speed of the barrel, the raising and lowering amplitude is controlled to decrease as the number of raising and lowering times increases; and / or, during the process of raising and lowering, it is determined whether the eccentricity value of the barrel decreases, and if so, the raising and lowering amplitude of the speed is controlled to decrease.

[0010] Furthermore, the lifting process includes several speed-up stages and several speed-down stages, and the speed-up durations corresponding to the several speed-up stages and / or the speed-down durations corresponding to the several speed-down stages decrease as the number of lifting times increases.

[0011] Furthermore, the lifting process includes an alternating speed-up phase and a speed-down phase, and the acceleration corresponding to the speed-down phase and the speed-up phase executed after the speed-down phase is controlled to be the same.

[0012] Furthermore, the maximum spin speed V is preset. max , during the process of barrel speed rising and falling, control the speed to rise to V max Then lower it.

[0013] Furthermore, the preset spin speed V max-1 , and V max-1 <V max In the speed-up phase, obtain the barrel speed V and compare the obtained speed V with the preset dehydration speed V max-1 If V ≥ V max-1 , the control reduces the acceleration during the speed-up phase.

[0014] Furthermore, in the deceleration stage, the barrel speed is first controlled from V max Drop to V1, then increase the speed and then from V max Reduce to V2, where V1<V max-1 <V2.

[0015] Furthermore, the preset spin speed V is controlled max-1 It is negatively correlated with the acquired eccentricity value.

[0016] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0017] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0018] In the present invention, the number of times the barrel body speed is raised and lowered is reasonably controlled according to the size of the eccentricity value of the barrel body, so that the escaped washing water can be discharged in time during the barrel body deceleration process, and water flow is avoided in the barrel body, so as to reduce the noise generated by the washing water hitting the barrel body wall in the eccentric state; in the barrel body acceleration process, the washing water can be fully shaken off the clothes, ensuring a high dehydration efficiency; at the same time, in the process of the barrel body speed rising and falling, the clothes in the barrel body can be fully turned over, which helps to evenly distribute the clothes in the barrel body, and then correct the eccentricity. In particular, the number of rises and falls selected according to the eccentricity value can correct the eccentricity without making the number of rises and falls too frequent to cause damage to the equipment.

[0019] In the present invention, the larger the eccentricity value obtained, the more serious the eccentricity of the barrel body. At this time, the number of lifting and lowering to control the barrel body speed is also greater, so that the clothes in the barrel body can be fully turned over, which helps to evenly distribute the clothes in the barrel body, thereby effectively correcting the eccentricity. At the same time, in the case of serious eccentricity of the barrel body, by increasing the number of lifting and lowering, the washing water can be frequently drained during the dehydration process, and the probability of the washing water hitting the barrel body wall is reduced as much as possible, so that even if the barrel body is eccentric, the noise generated is still small.

[0020] In this scheme, the speed increase and decrease amplitude is reasonably controlled according to the obtained eccentricity value. Once the eccentricity value decreases, it indicates that the current eccentricity of the barrel has been effectively corrected. At this time, the control rise and fall amplitude is reduced to avoid excessive changes in the barrel speed causing damage to the washing equipment. At the same time, in this scheme, as the dehydration program proceeds, the barrel speed will gradually maintain at a higher level, ensuring that the washing equipment has a better dehydration effect on clothes and a higher dehydration efficiency.

[0021] The washing device of the present invention is controlled by the dehydration control method of the present invention, is not easy to generate noise during the dehydration process, and has high dehydration efficiency and good dehydration effect, thereby improving the user experience.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other procedures, such as washing machines, washer-dryers, etc.; the washing equipment includes a barrel for holding clothes. When the washing equipment dehydrates, the barrel is controlled to rotate and centrifugal force is used to separate water from the clothes.

[0034] like Figures 1 to 5 As shown, the present invention discloses a dehydration control method for a washing device.

[0035] A dehydration control method for washing equipment, during the dehydration process, if the barrel is eccentric, the barrel speed is controlled to rise and fall to correct the eccentricity, the eccentricity value of the barrel is obtained, and the barrel speed is controlled to rise and fall according to the number of rise and fall times corresponding to the obtained eccentricity value. The number of rise and fall times refers to the total number of times the speed is increased and decreased.

[0036] Specifically, Figure 1 As shown, the control steps include:

[0037] S1, start dehydration;

[0038] S2, determine whether the barrel is eccentric; if so, execute step S3; if not, execute step S6;

[0039] S3, obtaining the eccentricity value of the barrel;

[0040] S4, selecting the lifting and lowering times corresponding to the obtained eccentricity value;

[0041] S5, controlling the speed to rise and fall according to the selected number of rise and fall times;

[0042] S6, determine whether the dehydration is completed; if so, execute step S7; if not, return to step S2;

[0043] S7. End.

[0044] Wherein, judging whether the barrel is eccentric in step S2 includes:

[0045] A vibration sensor is provided in the barrel of the washing equipment to obtain the vibration amount of the barrel. If the obtained vibration amount is greater than the preset vibration amount, it is determined that the barrel is eccentric.

[0046] Alternatively, the washing device has a box body, and the barrel body is arranged in the box body; the barrel body is hung in the box body through a suspension rod, and the bottom of the box body is provided with a foot, and n pressure sensors for detecting load-bearing force values ​​are respectively provided at both ends of the suspension rod or at different positions on the foot.

[0047] The method for obtaining the eccentricity value of the barrel includes: detecting and recording the detection value G of n pressure sensors 11 , G 12 …G 1n ; Calculate G 11 , G 12 …G 1n The difference between the maximum and minimum values ​​ΔG is taken as the eccentricity value.

[0048] In the present invention, judging whether the dehydration is completed in step S6 includes:

[0049] S61, cumulative dehydration time T';

[0050] S62, comparing the accumulated dehydration time T' with the preset dehydration time T; wherein the preset dehydration time T is positively correlated with the eccentricity of the barrel, and the larger the eccentricity of the barrel, the longer the corresponding preset dehydration time;

[0051] S63. If T' ≥ T, it is determined that the dehydration is completed; otherwise, it is determined that the dehydration is not completed.

[0052] Alternatively, in step S6 of the present invention, determining whether dehydration is completed includes:

[0053] S61', obtaining the water discharge volume Q within the preset time; wherein the preset time may be a factory preset value, for example: 1 minute, 30 seconds; or, the preset time is related to the total dehydration time, for example: if the preset total dehydration time is 10 minutes, the preset time is 1 / 20 of the total water discharge time;

[0054] S62', compare the obtained water displacement Q with the preset water displacement Q0, wherein the preset water displacement Q0 is close to 0; if Q<Q0, it is determined that the dehydration is completed, otherwise, it is determined that the dehydration is not completed.

[0055] In the present invention, the number of times the barrel speed is raised and lowered is reasonably controlled according to the eccentricity value of the barrel, so that the washing water can be discharged in time during the barrel speed reduction process, and the water flow in the barrel is avoided to reduce the noise generated by the washing water hitting the barrel wall in the eccentric state. During the barrel speed increase process, the washing water can be fully thrown off the clothes, ensuring a high dehydration efficiency.

[0056] At the same time, in the present invention, during the process of the barrel speed rising and falling, the clothes in the barrel can be fully turned over, which helps to evenly distribute the clothes in the barrel and further correct the eccentricity. In particular, the number of rises and falls selected according to the eccentricity value can correct the eccentricity without causing damage to the equipment by making the number of rises and falls too frequent.

[0057] As an embodiment of the present invention, the lifting times are controlled to be positively correlated with the obtained eccentricity value. For example:

[0058] If the eccentricity value obtained is in the high area, the speed is controlled to rise and fall F1 times during the dehydration process;

[0059] If the eccentricity value obtained is in the middle area, the speed is controlled to rise and fall F2 times during the dehydration process;

[0060] If the eccentricity value obtained is in the low area, the speed is controlled to rise and fall F3 times during the dehydration process;

[0061] Among them, F1>F2>F3.

[0062] In this embodiment, the larger the eccentricity value obtained, the more serious the eccentricity of the barrel body. At this time, the number of times the barrel body speed is controlled to rise and fall is also greater, so that the clothes in the barrel body can be fully turned over, which helps to evenly distribute the clothes in the barrel body and effectively correct the eccentricity.

[0063] At the same time, when the barrel is seriously eccentric, the number of lifting and lowering times is increased so that the washing water can be frequently discharged during the dehydration process, minimizing the probability of the washing water hitting the barrel wall. In this way, even if the barrel is eccentric, the noise generated is still relatively small.

[0064] As another embodiment of the present invention, its purpose is to provide a solution for controlling the speed increase or decrease range:

[0065] Option 1:

[0066] In the process of raising and lowering the barrel speed, the raising and lowering amplitude is controlled to decrease with the increase of the raising and lowering times. More specifically, the raising and lowering of the barrel speed includes the raising speed stage and the lowering speed stage. The raising amplitude in the raising speed stage is controlled to decrease with the increase of the raising speed times; the lowering amplitude in the lowering speed stage is controlled to decrease with the increase of the lowering speed times;

[0067] For example: the number of lifting and lowering is 4 times, including 2 speed-up stages and 2 speed-down stages. After the speed of the barrel rises to the maximum speed, the speed lifting and lowering process is: drop-rise-drop-rise; among them, the speed drops by 7r / min the first time, and by 4r / min the second time; the speed increases by 7r / min the first time, and by 4r / min the second time.

[0068] In this scheme, as the number of lifting and lowering times increases, a large amount of washing water is discharged, and the eccentricity is further corrected during the lifting and lowering of the barrel speed. In this way, the lifting and lowering amplitude of the speed is controlled to be reduced, thereby avoiding damage to the washing equipment caused by excessive changes in the barrel speed. At the same time, in this scheme, as the dehydration program proceeds, the barrel speed will gradually maintain at a higher level, ensuring that the washing equipment has a better dehydration effect on clothes and a higher dehydration efficiency.

[0069] Option 2:

[0070] During the lifting process, it is determined whether the eccentricity of the barrel decreases. If so, the lifting amplitude is controlled to reduce the rotation speed; otherwise, the lifting amplitude is controlled to remain unchanged.

[0071] In this scheme, the speed increase and decrease amplitude is reasonably controlled according to the obtained eccentricity value. Once the eccentricity value decreases, it indicates that the current eccentricity of the barrel has been effectively corrected. At this time, the control rise and fall amplitude is reduced to avoid excessive changes in the barrel speed causing damage to the washing equipment. At the same time, in this scheme, as the dehydration program proceeds, the barrel speed will gradually maintain at a higher level, ensuring that the washing equipment has a better dehydration effect on clothes and a higher dehydration efficiency.

[0072] On the contrary, if the eccentricity value does not decrease, it indicates that the current eccentricity of the barrel is still relatively serious. At this time, the speed control rise and fall amplitude is relatively high to achieve continued correction of the eccentricity of the barrel and ensure better correction effect and higher correction efficiency.

[0073] In this embodiment, one of Scheme 1 and Scheme 2 can be selected and applied in the dehydration process of the washing machine, or Scheme 1 and Scheme 2 can be combined and applied in the dehydration process at the same time.

[0074] As an implementation method of this embodiment, the lifting and lowering process includes several speed-up stages and several speed-down stages, and the speed-up time corresponding to the several speed-up stages decreases with the increasing number of lifting and lowering times; or, the speed-down time corresponding to the several speed-down stages decreases with the increasing number of lifting and lowering times; or the speed-up time corresponding to the several speed-up stages and the speed-down time corresponding to the several speed-down stages both decrease with the increasing number of lifting and lowering times.

[0075] For example: the barrel body includes 5 lifting processes: the first rising is t0 minutes - the first falling is t1 minutes - the second rising is t2 minutes - the first falling is t3 minutes - the third rising is t4 minutes; among them, t0>t2>t4; t1>t3.

[0076] In this embodiment, as the number of lifts and lowering increases, a large amount of washing water will be discharged. Therefore, in the subsequent dehydration process, there is no need to reserve a long time to drain the spun washing water. At this time, the speed increase time or the speed decrease time is controlled to be shortened, so that the barrel body can reach the target speed in a shorter time, thereby improving the dehydration efficiency and correcting the eccentricity in time.

[0077] As an embodiment of the present invention, the process of increasing and decreasing the speed of the barrel body includes an alternating speed-up phase and a speed-down phase, and the acceleration corresponding to the speed-down phase and the speed-up phase executed after the speed-down phase is controlled to be the same. Specifically, the barrel body is controlled to decrease in speed at an acceleration a, and then increases in speed at an acceleration a after decreasing in speed to a target speed.

[0078] In this embodiment, by controlling the acceleration of the deceleration stage and the acceleration stage executed after the deceleration to be the same, the purpose of draining the washing water in the deceleration stage is achieved, and the loss of the washing equipment during the dehydration process is minimized.

[0079] As another embodiment of the present invention, the maximum spin speed V is preset. max , during the process of barrel speed rising and falling, control the speed to rise to V max Then lower it.

[0080] Specifically, Figure 2 As shown, the control steps include:

[0081] S1, start dehydration;

[0082] S2, preset maximum spin speed V max ;

[0083] S3, determine whether the barrel is eccentric; if so, execute step S4; if not, execute step S8;

[0084] S4, obtaining the eccentricity value of the barrel;

[0085] S5, selecting the lifting and lowering times corresponding to the obtained eccentricity value;

[0086] S6, controlling the speed to rise and fall according to the selected number of rise and fall times;

[0087] S7, control the speed to rise to V max Then reduce the speed;

[0088] S8, determine whether the dehydration is completed; if so, execute step S9; if not, return to step S3;

[0089] S9. End.

[0090] In step S2 of this embodiment, the maximum dehydration speed V corresponding to different washing equipment or different loads is max Different. Maximum spin speed V max It refers to the maximum speed of the barrel when the washing equipment can operate safely, eccentricity is unlikely to occur during the dehydration process, and the noise generated is minimal. This maximum speed can be verified through multiple tests.

[0091] In this embodiment, during the process of controlling the barrel body speed to rise and fall, the barrel body speed is controlled to rise to the preset maximum dehydration speed V max In this way, the barrel speed can be increased to the maximum within the range allowed by the washing equipment. On the one hand, it ensures that the washing equipment has a better dehydration effect and a higher dehydration efficiency. On the other hand, it makes the clothes in the barrel flip more strongly, which helps to flip the clothes that cause the barrel eccentricity evenly in the barrel, and then correct the barrel eccentricity in the shortest time, thereby reducing the noise generation.

[0092] As an implementation of this embodiment, the dehydration control method of the washing equipment includes:

[0093] Preset spin speed V max-1 , and V max-1 <V max In the speed-up phase, obtain the barrel speed V and compare the obtained speed V with the preset dehydration speed V max-1 If V ≥ V max-1 , the control reduces the acceleration in the acceleration phase; if V<V max-1 , the acceleration in the speed-up phase is controlled to be larger.

[0094] In this embodiment, if the obtained speed V is greater than or equal to V max-1 , it indicates that the current rotation speed of the barrel is relatively large. If the speed is increased continuously at a large acceleration, the washing water thrown off the clothes will hit the barrel wall violently, thereby generating a large noise. Therefore, the acceleration in the speed-up stage is controlled to be reduced to weaken the potential energy of the washing water hitting the barrel wall, thereby reducing the noise.

[0095] On the contrary, if V<Vmax-1 , it indicates that the current rotation speed of the barrel is low. Although the washing water swung off the clothes may hit the barrel wall, the impact is light and will not produce a lot of noise. At this time, the control continues to increase the speed at a larger acceleration to ensure a high dehydration efficiency.

[0096] As another implementation method of this embodiment, during the barrel body speed reduction stage, the barrel body speed is first controlled from V max Drop to V1, then increase the speed and then from V max Reduce to V2, where V1<V max-1 <V2.

[0097] Specifically, Figure 4 and Figure 5 As shown in the figure, dehydration begins, and the barrel starts to rotate at an increasing speed. During the speed increase process, when the speed reaches V max-1 When the speed is reduced, the corresponding acceleration is controlled, and the speed of the barrel is controlled to change from V max-1 Rising to V max , control the barrel to V max Continue to rotate for t time, then control the speed to drop to V1 within t1 time, and then increase from V1 to V within t2 time. max Continue to rotate for t time, control the speed to drop to V2 within t3 time, and then increase from V2 to V within t4 time. max The machine rotates continuously for t time, then slows down to 0, completing the dehydration process. Among them, t0>t2>t4; t1>t3.

[0098] The amount of washing water in the barrel body decreases continuously from the beginning of dehydration to the completion of dehydration until it reaches 0 or is close to 0. The noise generated during the dehydration process also shows a trend of continuous decrease from the beginning of dehydration to the completion of dehydration.

[0099] Furthermore, if Figure 3 As shown, this embodiment includes the following control steps:

[0100] S1, start dehydration;

[0101] S2, preset maximum spin speed V max , dehydration speed V max-1 , speed V1, V2;

[0102] S3, determine whether the barrel is eccentric; if so, execute step S4; if not, execute step S13;

[0103] S4, obtaining the eccentricity value of the barrel;

[0104] S5, selecting the lifting and lowering times corresponding to the obtained eccentricity value;

[0105] S6, controlling the speed to rise and fall according to the selected number of rise and fall times;

[0106] S7, control the speed to rise to V max Then reduce the speed;

[0107] S8, speed-up stage, obtaining the speed V of the barrel;

[0108] S9: Determine whether the obtained speed V is greater than or equal to V max-1 If yes, then execute step S10; if no, then execute step S11;

[0109] S10, controlling to reduce the acceleration in the speed-up phase, and executing step S11;

[0110] S11, control the speed to V max ;

[0111] S12, speed from V max Down to V1, and up from V1 to V max , and then from V max Down to V2;

[0112] S13, determine whether the dehydration is completed; if so, execute step S14; if not, return to step S3;

[0113] S14, end.

[0114] In this embodiment, the rotation speed is V max In the process of decreasing to V1, due to the early stage of dehydration, there is more free water in the barrel and the barrel has become eccentric. At this time, in order to minimize the noise, the speed is controlled to decrease to V1, which is lower than V2, so as to drain as much washing water as possible at a low speed. max During the process of decreasing to V1, part of the washing water has been drained away, so the load weight in the barrel is small. At this time, the speed is reduced to V max-1 The following will not only not produce unnecessary noise, but will also help drain water and correct eccentricity.

[0115] As another implementation of this embodiment, the preset spin speed V is controlled max-1 It is negatively correlated with the acquired eccentricity value.

[0116] In this embodiment, the larger the eccentricity value obtained, the more serious the eccentricity of the barrel body, the greater the noise generated, and the preset dehydration speed V needs to be reduced. max-1 value, so that during the dehydration process, the process of adjusting the barrel speed can be entered as soon as possible, and the eccentricity can be corrected early to reduce the subsequent noise.

[0117] The present invention also provides a washing device, which is controlled by any control method described in the above technical solution. The washing device includes a barrel for accommodating clothes. When the washing device is dehydrating, the barrel is controlled to rotate and the water in the clothes is separated by centrifugal force.

[0118] The washing device of the present invention is controlled by the dehydration control method of the present invention, is not easy to generate noise during the dehydration process, and has high dehydration efficiency and good dehydration effect, thereby improving the user experience.

Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention.
