[0022] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0023] Figure 1 The flowchart of the dehydration control method provided by some embodiments of the present application is shown. Although the logical order is shown in the flowchart, in some cases, the operations shown or described may be performed in an order different from that shown in the drawings. The specific process of the dehydration control method may be as follows:
[0024] S101. Determine a plurality of eccentricity limit values.
[0025] The eccentricity limit value can be used to determine whether the eccentricity value of the clothes (load) in the washing machine is within a reasonable range. The eccentricity value of the clothes can measure the degree to which the clothes deviate from the rotation axis of the washing machine during the dehydration process.
[0026] If the washing machine is dehydrated at a high speed, the time required for dehydration can be reduced, but the eccentricity value of the clothes is also required to be small, so as to avoid large vibration, noise, and even drum collision in the washing machine. If the washing machine is dehydrated at a low speed, although the above problems can be avoided as much as possible, the dehydration efficiency is low. Therefore, it is necessary to determine the dehydration speed that matches the eccentricity value of the clothes to ensure the dehydration efficiency while reducing vibration and noise problems. To this end, the present embodiment can perform multiple rounds of attempts before formal dehydration.
[0027] Among them, multiple eccentricity limit values correspond to different trial round ranges. Different trial round ranges can correspond to different preset dehydration speeds. Among them, the preset dehydration speed can be used for the subsequent formal dehydration program. In the early trial rounds, a smaller eccentricity limit value can be used, that is, a more stringent judgment condition is used, so that the washing machine can use a higher speed for dehydration. When the eccentricity value does not meet the eccentricity limit condition in the early trial rounds, it is necessary to enter the later trial rounds. At this time, a larger eccentricity limit value can be used, that is, the judgment condition is appropriately relaxed. In order to avoid vibration, noise or drum collision problems, a lower speed is used for dehydration. Among them, different trial round ranges can be divided according to a preset method.
[0028] In some embodiments, the multiple eccentricity limits can be queried in a pre-established lookup table. In other embodiments, the multiple eccentricity limits can be calculated based on a mapping relationship between trial rounds and eccentricity limits.
[0029] In some embodiments, multiple eccentricity limits can be determined based on the range of trial rounds and the load weight. Under the same other conditions, the larger the load weight, the greater the problem caused by load eccentricity, so it is necessary to more strictly control the eccentricity value. For the same trial rounds, when the load weight is larger, the corresponding eccentricity limit is smaller.
[0030] S102. Determine a current eccentricity limit value corresponding to a current trial round according to multiple eccentricity limit values.
[0031] As mentioned above, multiple eccentricity limits may correspond to different trial round ranges, and different eccentricity limits are used for different trial round ranges. Therefore, the current eccentricity limit corresponding to the current trial round may be determined from the multiple eccentricity limits.
[0032] Among them, the current eccentricity limit is greater than or equal to the eccentricity limit in the previous trial round. As the trial rounds proceed, when the eccentricity value cannot meet the more stringent (smaller) eccentricity limit condition, the eccentricity limit requirement will be relaxed (increased) in the later trial rounds.
[0033] S103: Perform eccentricity detection, and determine the target operation based on the comparison between the eccentricity detection result and the current eccentricity limit value and the current trial round.
[0034] Among them, the eccentricity detection can be used to determine the eccentricity value of the clothes during the dehydration process. One trial round can include one eccentricity detection or multiple eccentricity detections. In one trial round, the test speed of the washing machine corresponding to multiple eccentricity detections gradually increases. Multiple eccentricity detections can improve the accuracy of judging the eccentricity of the load.
[0035] In some embodiments, the current eccentricity limit may include a low speed eccentricity limit and a resonant speed eccentricity limit. The speed at which the low speed eccentricity limit corresponds to the eccentricity detection is less than the speed at which the resonant speed eccentricity limit corresponds to the eccentricity detection. The low speed eccentricity limit is the eccentricity limit corresponding to the eccentricity detection when the test speed is low (less than the resonant speed) in the current attempt round. The resonant speed eccentricity limit is the eccentricity limit corresponding to the eccentricity detection when the test speed is high (near the resonant speed) in the current attempt round. There may be one or more low speed eccentricity limits, and there may also be one or more resonant speed eccentricity limits.
[0036] The target operation may include dehydrating at a preset speed corresponding to the current trial round, ending the trial process, or shaking the clothes before the next trial round. Specifically, how to determine the target operation based on the comparison of the eccentricity detection result with the current eccentricity limit value and the current trial round will be described in detail later.
[0037] Some embodiments of the present application provide a dehydration control method including determining a plurality of eccentricity limits, wherein the plurality of eccentricity limits correspond to different trial round ranges; determining a current eccentricity limit corresponding to a current trial round according to the plurality of eccentricity limits; and performing eccentricity detection, and determining a target operation based on a comparison between a result of the eccentricity detection and the current eccentricity limit and the current trial round. Some embodiments of the present application provide a dehydration control method capable of adjusting the current eccentricity limit according to the trial rounds of dehydration, thereby determining a target operation.
[0038] Figure 2 Schematic flow charts of dehydration control methods provided by other embodiments of the present application are shown. Although a logical order is shown in the flow chart, in some cases, the operations shown or described may be performed in an order different from that shown in the drawings. The specific flow chart of the dehydration control method may be as follows:
[0039] S201. Determine a plurality of eccentricity limit values.
[0040] S202. Determine a current eccentricity limit value corresponding to a current trial round according to multiple eccentricity limits.
[0041] S203, performing eccentricity detection.
[0042] Each round of eccentricity detection may include one or more attempts.
[0043] S204: Determine whether the result of the eccentricity detection is less than the current eccentricity limit value.
[0044] When the result of the eccentricity detection is less than the current eccentricity limit, the target operation is determined to be dehydration according to the preset speed corresponding to the current trial round, and operation S206 is performed. The preset speed corresponding to the current trial round is less than or equal to the preset speed corresponding to the previous trial round.
[0045] In a case where the result of the eccentricity detection is not less than the current eccentricity limit value, operation S205 is performed.
[0046] S205: Determine whether the current attempt round is less than the maximum number of attempts.
[0047] Wherein, the maximum number of attempts may be a value preset in advance. When the result of the eccentricity detection is greater than or equal to the eccentricity limit value, and the current round of attempts is less than the maximum number of attempts, the target operation is determined to be a shaking operation, and the next round of attempts is performed, and operation S207 is executed; otherwise, the attempt process is terminated.
[0048] In some embodiments, the determination of operation S205 may be performed before operation S204, and the present application does not limit the order of determination.
[0049] S206, dehydrating according to the preset rotation speed corresponding to the current trial round.
[0050] S207: Perform a shaking operation and proceed to the next round of attempts.
[0051] The shaking operation can make the clothes as evenly distributed as possible to reduce the eccentricity value, so that in subsequent rounds of attempts, the reduced eccentricity value can have a greater probability of meeting the eccentricity limit condition.
[0052] The dehydration control method provided by some embodiments of the present application can determine the target operation based on the result of the eccentricity detection and the current round of attempts. The eccentricity detection of each round of attempts may include one or more times, and the judgment accuracy can be improved by multiple eccentricity detections. When the eccentricity detection result is not less than the current eccentricity limit value and the current round of attempts is less than the maximum number of attempts, a shaking operation is performed and the next round of attempts is performed. The shaking operation can make the clothes as evenly distributed as possible to reduce the eccentricity value, so that in subsequent rounds of attempts, the reduced eccentricity value can have a greater probability of meeting the eccentricity limit condition.
[0053] Figure 3 An exemplary diagram of a dehydration control method provided by some embodiments of the present application is shown. Figure 3The maximum number of attempts shown is K, where K is a positive integer; the range of attempt rounds includes three ranges: 0 to (N1 - 1), N1 to (N2 - 1), and N2 to (K - 1), where N1 and N2 are positive integers, and N1 < N2 < K. The preset rotational speeds corresponding to the three attempt round ranges are the first rotational speed, the second rotational speed, and the third rotational speed respectively, where the first rotational speed is greater than the second rotational speed, and the second rotational speed is greater than the third rotational speed. The eccentricity detection corresponding to each attempt round is three times, including the first eccentricity detection, the second eccentricity detection, and the third eccentricity detection. The test rotational speed during the first eccentricity detection is less than the test rotational speed during the second eccentricity detection, and the test rotational speed during the second eccentricity detection is less than the test rotational speed during the third eccentricity detection. The process of this embodiment is introduced below:
[0054] First, determine the load weight.
[0055] Next, based on the attempt round range and the load weight, determine multiple eccentricity limits A, B, C, D, E, F, G, H, J. Among them, A < B < C, D < E < F, G < H < J. The above multiple eccentricity limits can be determined by looking them up in a lookup table.
[0056] Judge whether the current number of attempts is less than the maximum number of attempts K. When the judgment result is no, end the attempt process. When the judgment result is yes, continue to judge which range the current number of attempts falls into, and then determine the corresponding eccentricity limit.
[0057] If the current attempt round is within the range of 0 to (N1 - 1), the eccentricity limits for the three eccentricity detections are A, D, G respectively. If the current attempt round is within the range of N1 to (N2 - 1), the eccentricity limits for the three eccentricity detections are B, E, H respectively. If the current attempt round is within the range of N2 to (K - 1), the eccentricity limits for the three eccentricity detections are C, F, J respectively.
[0058] During the process of eccentricity detection in each attempt round, if the results of the three eccentricity detections all satisfy being less than the corresponding eccentricity limits, dehydrate at the preset rotational speed corresponding to the current attempt round, otherwise, perform a shaking and loosening operation and proceed to the next attempt round.
