Description

Technical Field

[0001] This application relates to the field of washing machine technology, and in particular to a washing machine spin-drying correction method and a washing machine. Background Technology

[0002] Washing machines require high-speed spin-drying. However, due to the structural limitations of drum washing machines, different clothes and washing conditions can lead to uneven water levels and clothing distribution inside the machine, making it difficult for drum washing machines to achieve high-speed spin-drying for different loads.

[0003] Many factors affect spin drying, including structure, electrical components, and program settings. To achieve fast and high-speed spin drying, proper alignment or smoothing of clothes is crucial. Alignment is more of a single action, but the load inside the drum can vary depending on the season, individual age, and even personal preferences, resulting in a variety of clothes and reduced spin drying efficiency. Summary of the Invention

[0004] This application provides a washing machine spin-drying correction method and a washing machine to solve the problem of low spin-drying efficiency.

[0005] Firstly, this application provides a method for correcting deviations during the spin-drying process of a washing machine, comprising:

[0006] Before responding to the spin-drying command received during the spin-drying process, a large eccentricity detection is performed on the washing machine to obtain the eccentricity value;

[0007] If the eccentricity value is less than or equal to the eccentricity value threshold, obtain the corresponding first loop count;

[0008] Determine whether the number of the first loop iterations is less than or equal to the iteration threshold;

[0009] If so, then according to the relationship between the first number of cycles and the preset number range, an eccentricity correction program corresponding to the first number of cycles is executed. The eccentricity correction program is used to control the washing machine's speed to drop to 0, and after adjusting the washing machine's speed to a first preset speed with a preset acceleration and maintaining it for a first preset time, the washing machine's speed is reduced to a second preset speed and maintained for a second preset time. Each time the eccentricity correction program is executed, the first number of cycles is incremented by 1.

[0010] Obtain the first loop count after the eccentricity correction procedure is executed; if the eccentricity correction procedure corresponding to the first loop count changes, re-execute the step of obtaining the eccentricity value until the eccentricity value is greater than the eccentricity value threshold.

[0011] In response to a dehydration command received during the dehydration process, the washing machine is instructed to execute a dehydration program.

[0012] In some feasible embodiments, the preset number interval is provided with a first constant and a second constant, and the eccentricity correction procedure includes a first eccentricity correction procedure and a second eccentricity correction procedure.

[0013] If the number of the first cycle is greater than twice the first constant, and the number of the first cycle is less than or equal to twice the second constant, a first eccentricity correction procedure is executed. The first eccentricity correction procedure includes reducing the rotation speed of the washing machine to 0, adjusting the rotation speed of the washing machine to a first rotation speed with a first acceleration and maintaining it for a first duration, and then reducing the rotation speed of the washing machine to a second rotation speed and maintaining it for a second duration.

[0014] If the first cycle count is less than or equal to twice the first constant, and the first cycle count is greater than twice the second constant, a second eccentricity correction procedure is executed. The second eccentricity correction procedure includes reducing the rotation speed of the washing machine to 0, adjusting the rotation speed of the washing machine to a third rotation speed with a second acceleration and maintaining it for a third duration, and then reducing the rotation speed of the washing machine to a fourth rotation speed and maintaining it for a fourth duration.

[0015] Wherein, the second constant is greater than the first constant, the second acceleration is greater than the first acceleration, the third rotational speed is greater than the first rotational speed, the fourth rotational speed is greater than the second rotational speed, the third duration is greater than the first duration, and the fourth duration is greater than the second duration.

[0016] In some feasible embodiments, the execution of the first eccentricity correction procedure includes:

[0017] Get the first attempt count;

[0018] If the first number of attempts is less than the first attempt threshold, execute the first eccentricity correction procedure;

[0019] If the first number of attempts is greater than or equal to the first number of attempts threshold, a large eccentricity test is performed on the washing machine to obtain the eccentricity value.

[0020] In some feasible embodiments, the second eccentricity correction procedure includes:

[0021] Get the second attempt;

[0022] If the second number of attempts is less than the second attempt threshold, execute the second eccentricity correction procedure;

[0023] If the second number of attempts is greater than or equal to the second number of attempts threshold, perform a large eccentricity test on the washing machine and obtain the eccentricity value.

[0024] In some feasible embodiments, the method further includes:

[0025] Get the number of first attempts and the number of second attempts;

[0026] If the first number of attempts is greater than or equal to the first number of attempts threshold, or if the second number of attempts is greater than or equal to the second number of attempts threshold;

[0027] Get the current loop count, which is the first loop count plus one.

[0028] In some feasible embodiments, the first constant is the set of even numbers consisting of 0, 2, 4, 6, and 8, and the second constant is the set of odd numbers consisting of 1, 3, 5, 7, and 9.

[0029] In some feasible embodiments, before obtaining the initial number of loops, the following steps are included:

[0030] If the eccentricity value is greater than the eccentricity value threshold, a stop command is sent to the washing machine to stop the washing machine from rotating.

[0031] In some feasible embodiments, before sending the stop command to the washing machine, the following steps are included:

[0032] If the eccentricity value is greater than the eccentricity value threshold;

[0033] The washing machine is subjected to eccentricity detection and weighing detection, and a spin-drying command is sent to the washing machine based on the detection results so that the washing machine can perform a spin-drying program;

[0034] If the spin-drying process is completed, a stop command is sent to the washing machine.

[0035] In some feasible embodiments, the method further includes:

[0036] If the number of the first cycle exceeds the threshold, a stop command is sent to the washing machine.

[0037] Secondly, this application provides a washing machine, the washing machine including a controller, the controller being configured to:

[0038] Before responding to the spin-drying command received during the spin-drying process, a large eccentricity detection is performed on the washing machine to obtain the eccentricity value;

[0039] If the eccentricity value is less than or equal to the eccentricity value threshold, obtain the corresponding first loop count;

[0040] Determine whether the number of the first loop iterations is less than or equal to the iteration threshold;

[0041] If so, then according to the relationship between the first cycle number and the preset number interval, an eccentricity correction program corresponding to the first cycle number is executed. The eccentricity correction program is used to control the washing machine speed to drop to 0, and after adjusting the washing machine speed to a first preset speed with a preset acceleration and maintaining it for a first preset time, the washing machine speed is reduced to a second preset speed and maintained for a second preset time. Each time the eccentricity correction program is executed, the first cycle number is incremented by 1.

[0042] Obtain the first loop count after the eccentricity correction procedure is executed; if the eccentricity correction procedure corresponding to the first loop count changes, then re-execute the step of obtaining the eccentricity value until the eccentricity value is greater than the eccentricity value threshold.

[0043] In response to a dehydration command received during the dehydration process, the washing machine is instructed to execute a dehydration program.

[0044] As can be seen from the above technical solutions, this application provides a washing machine spin-drying correction method and a washing machine. The method includes: before responding to a spin-drying command received during the spin-drying process, performing a large eccentricity detection on the washing machine to obtain an eccentricity value; if the eccentricity value is less than or equal to an eccentricity value threshold, obtaining the corresponding first cycle number; determining whether the first cycle number is less than or equal to a number threshold; if so, executing an eccentricity correction program corresponding to the first cycle number based on the relationship between the first cycle number and a preset number interval, the eccentricity correction program being used to control the washing machine's rotation speed to drop to 0, and after adjusting the washing machine's rotation speed to a first preset speed with a preset acceleration and maintaining it for a first preset time, the washing machine's rotation speed to a second preset speed and maintaining it for a second preset time; each time the eccentricity correction program is executed, the first cycle number is incremented by 1; obtaining the first cycle number after the eccentricity correction program is executed; if the eccentricity correction program corresponding to the first cycle number changes, re-executing the step of obtaining the eccentricity value until the eccentricity value is greater than the eccentricity value threshold; responding to a spin-drying command received during the spin-drying process to cause the washing machine to execute a spin-drying program. This application provides different correction procedures for different loads to solve the problem of low dehydration efficiency. Attached Figure Description

[0045] To more clearly illustrate the technical solution of this application, the drawings used in the embodiments will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0046] Figure 1 This is a schematic diagram of the washing machine spin-drying correction method shown in this embodiment;

[0047] Figure 2 This is a schematic diagram of a washing machine spin-drying correction method according to another embodiment. Detailed Implementation

[0048] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0049] See Figure 1 This application provides a method for correcting deviations during the spin-drying process of a washing machine, comprising:

[0050] S100: Before receiving a spin-drying command during the spin-drying process, perform large eccentricity detection on the washing machine to obtain the eccentricity value.

[0051] The spin-dry command instructs the washing machine to perform a spin-drying operation. In this embodiment, before performing the spin-drying operation, a large eccentricity detection is performed on the washing machine to determine the current eccentricity value UB. The eccentricity value UB indicates the degree to which the clothes deviate from the center during the spin-drying process.

[0052] Before performing large eccentricity detection, in order to ensure that the clothes are evenly distributed during the spin-drying process and reduce the eccentricity value, the clothes need to be normally leveled. The normal leveling process can be done manually or automatically by using the washing machine, for example, by rotating the contents of the washing machine within a certain range to level the clothes.

[0053] The eccentricity detection function in a washing machine is used to determine the balance of clothes during the spin-drying process. The eccentricity value indicates the degree to which the clothes deviate from the washing machine's axis of rotation. By detecting the eccentricity value, the washing machine can determine whether adjustments are needed to ensure the clothes are evenly distributed and achieve better spin-drying results.

[0054] When the washing machine detects significant eccentricity in the clothes (i.e., the clothes are unevenly distributed or severely unbalanced), it performs a large eccentricity detection. This detection allows the washing machine to take steps to correct the balance of the clothes before performing the spin cycle, reducing damage or accidents caused by imbalance.

[0055] Eccentricity detection is a routine balance test used to assess the balance of clothes and make corresponding adjustments. Large eccentricity detection, on the other hand, is an additional test performed under specific circumstances to address severe imbalances and take necessary corrective measures. In this embodiment, to solve the problem of low spin-drying efficiency, large eccentricity detection is used to test the washing machine.

[0056] S200: Determine whether the eccentricity value is less than or equal to the eccentricity value threshold.

[0057] In some embodiments, if the eccentricity value is greater than the eccentricity value threshold, a stop command is sent to the washing machine to stop the washing machine from rotating.

[0058] For example, the preset eccentricity threshold is K. If UB > K, a command to stop rotating is sent to the inner drum of the washing machine, and the inner drum of the washing machine changes from a rotating state to a non-rotating state.

[0059] See Figure 2 In some embodiments, if the eccentricity value exceeds an eccentricity threshold, eccentricity detection and load-bearing capacity detection of the clothes can be performed before sending a stop command to the washing machine. The machine then stops operating after the spin-drying cycle. Through eccentricity detection and load-bearing capacity detection, the washing machine can more accurately understand the state and distribution information of the clothes. Based on this state and distribution information, the washing machine can make appropriate adjustments, such as changing the rotation speed or adjusting the angle of the inner drum, to improve the spin-drying effect of the clothes.

[0060] S300: If the eccentricity value is less than or equal to the eccentricity value threshold, obtain the corresponding first loop count.

[0061] If UB≤K, enter the cyclic correction procedure and obtain the first loop count. The initial count of the first loop is 1. With each loop, the first loop count increases by 1. If the first loop count is set to N', then the current loop count N = N' + 1 for each loop. In this embodiment, N = (1, 2, 3, 4, ..., 20).

[0062] In some embodiments, if the eccentricity value is greater than the eccentricity value threshold, eccentricity detection and weighing detection are performed on the washing machine to send a spin-drying command to the washing machine based on the detection results, so that the washing machine can execute the spin-drying program. In response to the spin-drying command received during the spin-drying process, the washing machine can execute the spin-drying program. That is, when the eccentricity value is greater than the eccentricity value threshold, the spin-drying process of the washing machine is not corrected, and eccentricity detection and weighing detection are performed directly before the spin-drying operation is performed. In this embodiment, the spin-drying program may include pre-spinning and high-speed spin-drying.

[0063] S400: Determine whether the number of iterations in the first loop is less than or equal to the threshold number of iterations.

[0064] If not, that is, if the number of cycles N in the first cycle is greater than the threshold, the washing machine will be stopped directly.

[0065] The preset number of times threshold N0 is set. If N0 is 21, then in this embodiment, the correction program will be performed a maximum of twenty times. In this embodiment, if UB is still greater than K in the twentieth correction program, the washing machine will be controlled to perform eccentricity detection and weighing detection, and then the spin-drying program will be executed directly.

[0066] S500: If so, then execute the eccentricity correction procedure corresponding to the first cycle number based on the relationship between the first cycle number and the preset cycle number range.

[0067] In some embodiments, the preset frequency interval is provided with a first constant and a second constant. The first constant is the set of even numbers consisting of 0, 2, 4, 6, and 8, and the second constant is the set of odd numbers consisting of 1, 3, 5, 7, and 9. The second constant is greater than the first constant. For example, if the first constant is set as A and the second constant is set as B, then the preset frequency interval is (A, B], where A = (0, 2, 4, 6, 8) and B = (1, 3, 5, 7, 9).

[0068] The eccentricity correction program is used to control the washing machine's speed to drop to 0, and then adjust the washing machine's speed to a first preset speed with a preset acceleration and maintain it for a first preset time, and then reduce the washing machine's speed to a second preset speed and maintain it for a second preset time; each time the eccentricity correction program is executed, the first cycle count is incremented by 1.

[0069] In some embodiments, the eccentricity correction procedure includes a first eccentricity correction procedure and a second eccentricity correction procedure. It is understood that the preset acceleration includes different accelerations in the first eccentricity correction procedure and the second eccentricity correction procedure, the first preset rotational speed and the second preset rotational speed include different rotational speeds in the first eccentricity correction procedure and the second eccentricity correction procedure, and the first preset duration and the second preset duration include different durations in the first eccentricity correction procedure and the second eccentricity correction procedure.

[0070] The relationship between the number of first loops and the preset number range includes the following: the number of first loops is greater than twice the first constant, and the number of first loops is less than or equal to twice the second constant; and the number of first loops is less than or equal to twice the first constant, and the number of first loops is greater than twice the second constant.

[0071] If the number of the first cycle is greater than twice the first constant, and the number of the first cycle is less than or equal to twice the second constant, a first eccentricity correction procedure is executed. The first eccentricity correction procedure includes reducing the speed of the washing machine to 0, adjusting the speed of the washing machine to the first speed with a first acceleration and maintaining it for a first duration, and then reducing the speed of the washing machine to the second speed and maintaining it for a second duration.

[0072] For example, after large eccentricity detection, the inner drum of the washing machine is kept rotating. When 2A < N ≤ 2B, the rotation speed of the inner drum is reduced to 0, then increased to R1 rpm with a first acceleration a1 and maintained for t1. Then, the rotation speed of the inner drum is reduced from R1 rpm to R2 rpm and maintained for t2. In other words, different correction procedures are provided for different types and quantities of loads.

[0073] In some embodiments, after executing the first eccentricity correction procedure, the first number of attempts is obtained; if the first number of attempts is less than the first number of attempts threshold, the first eccentricity correction procedure is executed; if the first number of attempts is greater than or equal to the first number of attempts threshold, a large eccentricity test is performed on the washing machine to obtain the eccentricity value.

[0074] The first attempt count refers to the number of times the first eccentricity correction procedure is executed. The initial value of the first attempt count is 1. That is, when the first attempt count is obtained, the first eccentricity correction procedure is executed once, i.e., the initial value is 1. Similarly, the first attempt count is incremented by 1 each time the first eccentricity correction procedure is executed. That is, n = n' + 1.

[0075] Setting a first attempt threshold n1 can limit the number of times the first eccentricity correction procedure can be executed. Eccentricity can be corrected within the threshold number of attempts, thereby improving dehydration efficiency.

[0076] In some embodiments, if the number of first attempts is greater than or equal to the threshold number of first attempts, the current loop count is obtained, which is the number of the first loop plus one.

[0077] For example, when n < n1, the first eccentricity correction procedure is re-executed until n ≥ n1, then the large eccentricity detection is re-executed to obtain the eccentricity value again for the next cycle of eccentricity correction procedure. In this case, the current first cycle count is the first cycle count plus one.

[0078] If the number of the first cycle is less than or equal to twice the first constant, and the number of the first cycle is greater than twice the second constant, a second eccentricity correction procedure is executed. The second eccentricity correction procedure includes reducing the speed of the washing machine to 0, adjusting the speed of the washing machine to a third speed with a second acceleration and maintaining it for a third duration, and then reducing the speed of the washing machine to a fourth speed and maintaining it for a fourth duration.

[0079] For example, after a large eccentricity detection, the inner drum of the washing machine is kept rotating. When 2A ≥ N > 2B, the speed of the inner drum is reduced to 0, then increased to R3 rpm with a second acceleration a2 and maintained for t3. After that, the speed of the inner drum is reduced from R3 rpm to R4 rpm and maintained for t4. In other words, different correction procedures are provided for different types and quantities of loads.

[0080] In some embodiments, after executing the second eccentricity correction procedure, the second number of attempts is obtained; if the second number of attempts is less than the second number of attempts threshold, the second eccentricity correction procedure is executed; if the second number of attempts is greater than or equal to the second number of attempts threshold, a large eccentricity test is performed on the washing machine to obtain the eccentricity value.

[0081] The second attempt count refers to the number of times the second eccentricity correction procedure is executed. The initial value of the second attempt count is 1. That is, when the second attempt count is obtained, the second eccentricity correction procedure is executed once, i.e., the initial value is 1. Similar to the first loop count, the second attempt count is incremented by 1 each time the second eccentricity correction procedure is executed. That is, n2 = n2' + 1.

[0082] Setting a second attempt threshold n1 can limit the number of times the second eccentricity correction procedure can be executed. Eccentricity can be corrected within the threshold number of attempts, thereby improving dehydration efficiency.

[0083] In some embodiments, if the number of second attempts is greater than or equal to the threshold number of second attempts, the current loop count is obtained, which is the number of the first loop plus one.

[0084] For example, when n2 < n3, the second eccentricity correction procedure is re-executed until n2 ≥ n3. Then, the large eccentricity detection is re-executed to obtain the eccentricity value again for the next cycle of eccentricity correction procedure. In this case, the current first cycle count is the first cycle count plus one.

[0085] To enable the first and second eccentricity correction programs to correspond to different load types and different load quantities, in some embodiments, the first rotational speed is greater than the second rotational speed, the third rotational speed is greater than the fourth rotational speed, the third rotational speed is greater than the first rotational speed, and the fourth rotational speed is greater than the second rotational speed. The first duration is greater than the second duration, the third duration is greater than the fourth duration, the third duration is greater than the first duration, the fourth duration is greater than the second duration, and the second acceleration is greater than the first acceleration.

[0086] For example, when the third rotational speed is greater than the first rotational speed, the fourth rotational speed is greater than the second rotational speed, the third duration is greater than the first duration, the fourth duration is greater than the second duration, and the second acceleration is greater than the first acceleration, that is, when the rotational speed, duration, and acceleration of the second eccentricity correction program are all greater than those of the first eccentricity correction program, the load correction force of the second eccentricity correction program can be increased, thereby increasing the correction intensity.

[0087] S600: Get the first loop count after the eccentricity correction program is executed.

[0088] After one or more first and second eccentricity correction procedures, the number of the first cycle will change, and the number of the first cycle will be obtained again, which is the current number of the first cycle.

[0089] S700: If the eccentricity correction procedure corresponding to the first loop number changes, the step of obtaining the eccentricity value is re-executed until the eccentricity value is greater than the eccentricity value threshold.

[0090] Each time an eccentricity correction procedure is performed, that is, after the first and second eccentricity correction procedures are completed, a large eccentricity detection is performed again until the eccentricity value obtained from the large eccentricity detection is greater than the eccentricity value threshold, at which point the eccentricity procedure stops.

[0091] S800: In response to a spin-drying command received during the spin-drying process, the washing machine is instructed to execute the spin-drying program.

[0092] When the eccentricity value is greater than the eccentricity value threshold, a dehydration process is initiated.

[0093] Based on the above-described washing machine spin-drying correction method, some embodiments of this application also provide a washing machine, which includes a controller configured to:

[0094] Before responding to the spin-drying command received during the spin-drying process, a large eccentricity detection is performed on the washing machine to obtain the eccentricity value;

[0095] If the eccentricity value is less than or equal to the eccentricity value threshold, obtain the corresponding first loop count;

[0096] Determine if the number of iterations in the first loop is less than or equal to the threshold number of iterations;

[0097] If so, then based on the relationship between the first cycle count and the preset count interval, the eccentricity correction program corresponding to the first cycle count is executed. The eccentricity correction program is used to control the washing machine's speed to drop to 0, and after adjusting the washing machine's speed to the first preset speed with a preset acceleration and maintaining it for the first preset time, the washing machine's speed is reduced to the second preset speed and maintained for the second preset time. Each time the eccentricity correction program is executed, the first cycle count is incremented by 1.

[0098] Obtain the first loop count after the eccentricity correction procedure is executed; if the eccentricity correction procedure corresponding to the first loop count changes, re-execute the step of obtaining the eccentricity value until the eccentricity value is greater than the eccentricity value threshold.

[0099] In response to a spin-drying command received during the spin-drying process, the washing machine is instructed to execute the spin-drying program.

[0100] It is understood that the controller in this embodiment can be the controller of a washing machine or the controller of the spin-drying module in the washing machine.

The method includes: before responding to a spin-drying command received during the spin-drying process, performing a large eccentricity detection on the washing machine to obtain an eccentricity value; if the eccentricity value is less than or equal to an eccentricity value threshold, obtaining the corresponding first cycle count; determining whether the first cycle count is less than or equal to the count threshold; if so, executing an eccentricity correction program corresponding to the first cycle count based on the relationship between the first cycle count and a preset count interval, the eccentricity correction program being used to control the washing machine's rotation speed to drop to 0, and after adjusting the washing machine's rotation speed to a first preset speed with a preset acceleration and maintaining it for a first preset duration, the washing machine's rotation speed is reduced to a second preset speed and maintained for a second preset duration; each time the eccentricity correction program is executed, the first cycle count is incremented by 1; obtaining the first cycle count after the eccentricity correction program is executed; if the eccentricity correction program corresponding to the first cycle count changes, re-executing the step of obtaining the eccentricity value until the eccentricity value is greater than the eccentricity value threshold; responding to a spin-drying command received during the spin-drying process to cause the washing machine to execute a spin-drying program.
